Description

[Technical Field]

[0001] This application claims priority to Chinese patent application No. 201910875287.5, filed on September 17, 2019, with the Patent Office of the People's Republic of China, entitled "Liquid Treatment Apparatus and Heat Exchange Apparatus," and to Chinese patent applications Nos. 201911187642.6 and 201911187634.1, filed on November 28, 2019, with the Patent Office of the People's Republic of China, entitled "Heat Exchange Box and Liquid Heating Apparatus" and "Liquid Heating Apparatus and Control Method, Control Device, and Readable Storage Medium Therefor," the entire contents of which are incorporated herein by reference.

[0002] This application relates to the household appliances field, specifically ,liquid Body heating device, method for controlling liquid heating device, and control of liquid heating device assembly and a computer-readable storage medium. [Background technology]

[0003] While instant-heat electric kettle-type liquid treatment devices can provide water at multiple temperatures, conventional instant-heat electric kettles simply heat water to a specific temperature in the non-boiling stage and then dispense the water directly. In this case, since the water is not boiled, it is difficult to kill bacteria and microorganisms in the water. As a result, the cleanliness and hygiene of the hot water provided by instant-heat electric kettles in the non-boiling stage cannot be ensured.

[0004] Therefore, how to propose a liquid treatment device that can ensure the cleanliness and hygiene of the hot water provided at the hot water stage is an issue that needs to be resolved as soon as possible. Summary of the Invention [Problem to be solved by the invention]

[0005] The present application aims to solve at least one of the above technical problems.

[0006] It is therefore an object of a first aspect of the present application to provide a liquid treatment device.

[0007] An object of a second aspect of the present application is to provide a heat exchange device.

[0008] An object of a third aspect of the present application is to provide a heat exchange box.

[0009] An object of a fourth aspect of the present application is to provide a liquid heating appliance having the heat exchange box of the third aspect.

[0010] An object of a fifth aspect of the present application is to provide a liquid heating appliance.

[0011] An object of a sixth aspect of the present application is to provide a method for controlling a liquid heating appliance.

[0012] An object of a seventh aspect of the present application is to provide a control device for a liquid heating appliance.

[0013] An object of an eighth aspect of the present application is to provide a computer-readable storage medium. [Means for solving the problem]

[0014] To achieve the above object, the technical means of a first aspect of the present application provides a liquid treatment device including a liquid supply passage, a liquid discharge passage, a heat exchange device, and a heating assembly. The heat exchange device is in communication with the liquid supply passage and the liquid discharge passage, and can transport liquid that has entered the heat exchange device to the liquid discharge passage after heat exchange, and the heating assembly is provided corresponding to the liquid supply assembly and / or the heat exchange device, or a heating passage connected between the liquid supply passage and the heat exchange device is provided within the heating assembly.

[0015] The liquid treatment device according to the present application includes a liquid supply channel, a heating assembly, a liquid discharge channel, and a heat exchanger. The liquid supply channel may be directly connected to an external water source, such as a user's home water pipe, to supply water via the user's home water pipe. Of course, the liquid supply channel may also be connected to an internal or external liquid supply tank to supply water via a liquid supply tank. On the other hand, the liquid supply channel may be a channel within a member independent of the heat exchanger and heating assembly, or may be a single internal channel within the heat exchanger. The heating assembly is for heating. Specifically, the heating assembly may be provided within or outside the liquid supply channel corresponding to the liquid supply channel to heat the water in the liquid supply channel, or the heating assembly may be provided within or outside the heat exchanger corresponding to the heat exchanger to heat the water in the heat exchanger. Of course, the heating assembly may be provided as a structure including a heating flow path, and the heating assembly may be connected between the liquid supply flow path and the heat exchanger so that the heat exchanger can communicate with the liquid supply flow path via the heating flow path. In this case, water entering from the liquid supply flow path first enters the heating flow path, is heated in the heating flow path, enters the heat exchanger, and is heat exchanged through the heat exchanger before flowing out from the liquid discharge flow path. In this embodiment, the liquid supply flow path may be a flow path within a member provided independently of the heating assembly and the heat exchanger, or it may be an internal flow path that communicates with the heating flow path within the heating assembly. On the one hand, the heat exchanger is provided corresponding to the liquid discharge flow path and can cool the liquid in the liquid discharge flow path so that the liquid in the liquid discharge flow path can be cooled to an appropriate temperature before being discharged. On the other hand, a heat exchanger may be provided between the heating assembly and the liquid discharge flow path and communicated with the heating flow path and the liquid discharge flow path. In this way, hot water heated by the heating device can be cooled through the heat exchanger before being transported into the liquid discharge flow path and discharged from the liquid discharge flow path. The liquid discharge flow path here may be a flow path provided independently within the external member of the heat exchange device, or, of course, may be a single built-in flow path within the heat exchange device.With this structure, when hot water below boiling temperature (e.g., 25°C-70°C) needs to be provided, the water can be heated to a relatively high temperature using the heating assembly, up to the boiling temperature. After the water is heated to the relatively high temperature, it can be transported to the liquid outlet channel and cooled using a heat exchanger in the liquid outlet channel, or the water can be heated using the heating assembly and then directly transported to the heat exchanger, cooled through the heat exchanger, transported to the liquid outlet channel, and discharged through the liquid outlet channel for drinking by the user. With this structure, the relatively high-temperature water can be cooled through the heat exchanger to a relatively low temperature, such as a temperature specified by the user or a temperature that is easy for the user to drink, and then the cooled water can be discharged through the water outlet of the liquid outlet channel. In this way, when providing relatively low-temperature water, high-temperature sterilization or disinfection can be achieved by first heating the water to a relatively high temperature using the heating assembly, thereby killing bacteria and microorganisms in the water. This allows bacteria and other contaminants to be removed in advance when providing water at the specified temperature, thereby ensuring cleanliness and hygiene when the product provides relatively low-temperature hot water.

[0016] The liquid treatment device according to one possible design of the present application may also have the following additional technical features:

[0017] In one possible design, the liquid treatment device further includes a liquid supply assembly and a liquid discharge assembly, the liquid supply passage being disposed in the liquid supply assembly and the liquid discharge passage being disposed in the liquid discharge assembly.

[0018] In this design, the liquid treatment device further includes a liquid supply assembly and a liquid discharge assembly. The liquid supply assembly is connected to a water source and is used to supply water to the heat exchange device or heating channel, and the liquid discharge assembly is used to discharge water from the heat exchange device outlet. Such a liquid treatment device includes a separate liquid supply assembly, heat exchange device, and liquid discharge assembly, which allows the overall product to be relatively simple in terms of components, making the product easier to process. Of course, in another embodiment, the liquid supply assembly and liquid discharge assembly do not need to be separate. In this case, the liquid supply channel, liquid discharge channel, heating assembly, and heat exchange device may be integrated into an integrated component that provides water supply, heating, heat exchange, and hot water supply. Of course, in yet another embodiment, the heat exchange device, liquid discharge channel, and liquid supply channel may be integrated, but the heating assembly may be provided as a separate component. Of course, the heating assembly and liquid supply channel may be integrated, in which case the heat exchange device and liquid discharge channel may be integrated or each may be a separate component.

[0019] In one possible design, a heating flow path is provided within the heating assembly, and if the heating flow path is connected between the liquid supply flow path and the heat exchange device, the heating assembly and the liquid supply assembly are separate structures, and if the heating assembly is provided corresponding to the liquid supply assembly, the heating assembly is provided within the liquid supply flow path, and if the heating assembly is provided corresponding to the heat exchange device, the heating assembly is provided within the heat exchange device.

[0020] In this design, the heating assembly may be provided as a structure including a heating flow path, and the heat exchanger may be connected between the liquid supply flow path and the heat exchanger so that the heat exchanger can communicate with the liquid supply flow path through the heating flow path. In this case, water entering from the liquid supply flow path first enters the heating flow path, is heated in the heating flow path, enters the heat exchanger, and is heat exchanged through the heat exchanger before flowing out from the liquid discharge flow path. In this case, the heating assembly, the heat exchanger, and the liquid supply device may be separate structures, i.e., the heating assembly may be a structure independent of the heat exchanger and the liquid supply device. Of course, in another embodiment, the heating assembly, the heat exchanger, and the liquid supply device may be an integral structure, for example, an integrally assembled structure or an integrally molded structure. In yet another embodiment, the heating assembly may be directly provided in the heat exchanger, in which case the liquid can be directly heated in the heat exchanger. Of course, the heating assembly may also be directly provided in the liquid supply flow path so that the liquid can be directly heated in the liquid supply flow path. When the heating assembly is provided in the heat exchange device or the liquid supply passage, the heating assembly and the heat exchange device or the liquid supply passage may be of an integral structure or of a separate structure.

[0021] A heat exchange passage may be provided within the heat exchange device so that the liquid that has entered the heat exchange passage can be transported to the liquid discharge passage after heat exchange, or a non-heat exchange passage may be provided within the heat exchange device, in which case the liquid that has entered the non-heat exchange passage can be transported directly to the liquid discharge passage without being cooled. That is, although the heat exchange device has a heat exchange function for cooling water, it does not necessarily mean that the liquid that has entered the heat exchange device must be transported to the liquid discharge passage after being subjected to heat exchange. In other words, the liquid that has passed through the heat exchange device can directly flow out without being subjected to heat exchange.

[0022] In one possible design, the heat exchange device includes a first heat exchange passage and a second heat exchange passage, the second heat exchange passage communicating with the liquid supply passage and the liquid discharge passage, and the first heat exchange passage capable of exchanging heat with the second heat exchange passage to cool the liquid in the second heat exchange passage.

[0023] In this design, the heat exchange device may include a first heat exchange passage and a second heat exchange passage, and the second heat exchange passage may be connected to the liquid supply passage and the liquid discharge passage. In this way, the liquid, such as water, heated by the heating assembly can be cooled by heat exchange with the first heat exchange passage in the second heat exchange passage and then discharged through the liquid discharge assembly. The temperature of the high-temperature liquid heated by the heating assembly when flowing through the second heat exchange passage is higher than the temperature of the cooling liquid in the first heat exchange passage. Therefore, the first heat exchange passage can continuously absorb heat from the liquid, such as water, in the second heat exchange passage to realize heat exchange between the first and second heat exchange passages. Therefore, the liquid, such as water, in the second heat exchange passage can be cooled by heat exchange between the first and second heat exchange passages. This structure utilizes the principle of heat exchange to cool the liquid, such as water, heated by the heating device. This cooling method is simple and easy to implement, thereby simplifying the structure of the product and reducing the cost of the product. Of course, other cooling methods may be used, such as air cooling using a fan, in which case the heat exchange device may be an air-cooling device.

[0024] In one possible design, if a heating flow path is provided within the heating assembly, the second heat exchange flow path communicates with the liquid supply flow path via the heating flow path, and if a heating assembly is provided within the heat exchange flow path, the heating assembly is provided within the second heat exchange flow path.

[0025] In this design, if a heating flow path is provided within the heating assembly, the second heat exchange flow path can be connected to the liquid supply flow path via the heating flow path, thereby allowing a liquid such as water to pass sequentially through the liquid supply flow path and the heating flow path and enter the second heat exchange flow path; on the other hand, if a heating assembly is provided within the heat exchange device, the heating assembly can be provided within the second heat exchange flow path so as to directly heat the water in the second heat exchange flow path, in which case the first half of the second heat exchange flow path can be used for heating and the second half can be used for heat exchange cooling of the liquid such as water.

[0026] In one possible design, the inlet of the first heat exchange passage communicates with the liquid supply passage, and if the second heat exchange passage communicates with the liquid supply passage via the heating passage, the outlet of the first heat exchange passage communicates with the inlet of the heating passage or with the liquid supply passage.

[0027] In this design, the first heat exchange channel can communicate with the liquid supply channel and the inlet of the heating channel, while the outlet of the heating channel is connected to the second heat exchange channel. Therefore, in this application, the liquid supply channel, the first heat exchange channel, the heating channel, and the second heat exchange channel are connected end-to-end. This allows liquid, such as water, entering through the liquid supply channel to first pass through the first heat exchange channel of the heat exchange device, then enter the heating channel from the first heat exchange channel, and then enter the second heat exchange channel from the heating channel. After heat exchange between the second heat exchange channel and the first heat exchange channel, the liquid flows out through the outlet of the liquid discharge channel. This configuration allows the low-temperature liquid (i.e., unheated liquid) entering the liquid supply channel to cool the liquid entering the second heat exchange channel after heating. This eliminates the need for a separate cooling fluid or a separate cooling circuit. Simply by rationally configuring the liquid flow path structure within the product, cooling costs can be reduced. After heat exchange between the first and second heat exchange paths, the liquid in the first heat exchange path absorbs heat from the liquid, such as water, in the second heat exchange path, causing it to rise in temperature. However, the heated cooling liquid can then enter the heating path directly and be heated. This reduces the amount of heat required to boil the liquid in the heating path. This structure allows water before heating to be used to cool the liquid, such as water after heating, and the cooling liquid that has absorbed the heat can be directly transported into the heating path to heat the water to the desired temperature. This allows the excess heat in the heated water to be fully utilized, improving the heat utilization rate of the product.

[0028] In another design, the inlet of the first heat exchange passage may be connected to the liquid supply passage, and then the outlet of the first heat exchange passage may be connected directly to the liquid supply passage rather than to the inlet of the heating passage. In this way, the liquid entering the first heat exchange passage from the liquid supply passage can be heat exchanged with the second heat exchange passage to heat the liquid in the liquid supply passage, and then returned to the liquid supply passage via the first heat exchange passage, thereby increasing the temperature of the liquid entering the heating passage and realizing the recovery and utilization of heat in the first heat exchange passage. In one possible design, a liquid storage tank may be connected to the liquid supply passage so that the liquid in the liquid supply passage can first enter the liquid storage tank, and the inlet and outlet of the first heat exchange passage may be connected to the liquid storage tank, and the inlet of the heating passage may also be connected to the liquid storage tank. In this way, on the one hand, the liquid storage tank can form a cooling circulation circuit together with the first heat exchange passage to realize cooling of the second heat exchange passage, and on the other hand, the liquid storage tank can heat the liquid entering the heating passage using hot water that has absorbed heat in the first heat exchange passage to realize heat reuse.

[0029] In one possible design, the heat exchange device further comprises a reservoir tank connected to the inlet of the first heat exchange channel and to the outlet of the first heat exchange channel to form a refrigeration circulation circuit.

[0030] In this design, a liquid storage tank may be additionally provided to form a circuit with the first heat exchange flow path via the liquid storage tank, thereby constantly providing cooling power to cool the liquid, such as water, in the liquid discharge flow path. This structure allows the cooling circuit to be independent of the liquid flow path consisting of the liquid supply assembly, heating assembly, and liquid discharge assembly, thereby allowing the cooling circuit and the liquid flow path to operate independently, thereby allowing the cooling circuit to be turned on or off independently. In this way, whether to turn on the cooling circuit can be determined according to actual demand when the liquid treatment device is operating. When the cooling circuit is not turned on, heated water can be directly discharged at a corresponding temperature, such as boiling water. When the cooling circuit is turned on, water can first be heated to a relatively high temperature, such as boiling, and then cooled to a relatively low temperature before being discharged. This structure allows the product to directly heat water and discharge it, or to first heat and cool water before discharging it, thereby expanding product functionality and achieving product diversification, thereby enabling the product to better meet various user needs.

[0031] In one possible design, when a heating flow path is provided in the heating assembly, the reservoir tank is in communication with the liquid supply flow path, and the heating flow path is directly connected to the liquid supply flow path, or the inlet of the heating flow path is connected to the reservoir tank so that it is connected to the liquid supply flow path via the reservoir tank.

[0032] In this design, a heating flow path is provided in the heating assembly and is connected between the liquid supply flow path and the heat exchange device, and when the heat exchange device is in communication with the liquid supply flow path through the heating flow path, a liquid storage tank can be connected between the inlet of the heating flow path and the liquid supply flow path, so that on the one hand, coolant can be added to the liquid storage tank through the liquid supply assembly, and on the other hand, the heat after heat exchange between the first heat exchange path and the second heat exchange path can be returned to the liquid storage tank through the first heat exchange path and heat the liquid in the liquid storage tank. Considering that the heating flow path is also connected to the liquid storage tank, the heat after cooling heat exchange in the liquid storage tank can be used to preheat the liquid such as water entering the heating flow path, thereby making full use of the heat from the heat exchange. In another aspect, both the heating flow path and the liquid storage tank can be directly connected to the liquid supply flow path so that water can be simultaneously supplied to the liquid storage tank and the heating flow path through the liquid supply flow path. In this case, the liquid can be cooled by the cryogenic liquid that has entered the liquid supply flow path, but the heat from the heat exchange in the first heat exchange path cannot be reused. However, in either embodiment, the cooling circulation channel can be independent of the liquid channel, and therefore can be turned on or off independently without being affected by the liquid channel.

[0033] In one possible design, the reservoir tank is in communication with the liquid supply channel, and the inlet of the heating channel is connected to the reservoir tank so as to be connected to the liquid supply channel via the reservoir tank, a first pumping device is provided between the reservoir tank and the liquid supply channel, and / or a second pumping device is provided between the inlet of the heating channel and the reservoir tank, and / or a third pumping device is provided between the first heat exchange channel and the reservoir tank.

[0034] In this design, a liquid storage tank can be connected between the inlet of the heating flow path and the liquid supply flow path; thus, on the one hand, cooling liquid can be added to the liquid storage tank through the liquid supply flow path of the liquid supply assembly; and on the other hand, the heat after heat exchange between the first heat exchange flow path and the second heat exchange flow path can be returned to the liquid storage tank through the first heat exchange flow path and used to heat the liquid in the liquid storage tank. Considering that the heating flow path is also connected to the liquid storage tank, this allows the heat after cooling heat exchange in the liquid storage tank to be used to preheat the liquid, such as water, that enters the heating flow path, thereby making full use of the heat from the heat exchange. In this embodiment, a first pumping device may be provided between the storage tank and the liquid supply channel to pump the liquid in the liquid supply channel into the storage tank by the first pumping device, a second pumping device may be provided between the inlet of the heating channel and the storage tank to pump the liquid in the storage tank into the heating channel by the second pumping device, and a third pumping device may be provided between the first heat exchange channel and the storage tank to pump the liquid in the storage tank into the first heat exchange channel by the third pumping device. This arrangement allows for control of the flow rate in the first heat exchange channel via the third pumping device, thereby controlling the cooling effect of the heat exchange device. Note that the third pumping device may be turned off to turn the first heat exchange channel on or off, thereby controlling the on or off of the cooling function via the third pumping device. Note that providing these three pumping devices allows for greater liquid flow pressure and faster flow rate. At the same time, the effect of controlling the liquid flow rate can be achieved by adjusting the flow rate through each pumping device.

[0035] In one possible design, the liquid treatment device further includes a temperature collection element disposed within the reservoir tank for collecting the temperature of the liquid within the reservoir tank.

[0036] In this design, a temperature collection element is used to collect the temperature of the liquid in the reservoir tank so that the flow rate of the cooling liquid in the first heat exchange flow path can be controlled based on the temperature of the liquid in the reservoir tank and further the cooling intensity can be controlled.

[0037] In one possible design, when a heating flow path is provided in the heating assembly and a second heat exchange flow path is in communication with the liquid supply flow path through the heating flow path, the liquid treatment device further includes a three-way valve, the inlet of which is connected to the outlet of the heating flow path and the first outlet of which is connected to the second heat exchange flow path, and the liquid discharge assembly further includes a branch flow path, one end of which is connected to the second outlet of the three-way valve and the other end of which is connected to the liquid discharge flow path.

[0038] In this design, a heating flow path is provided in the heating assembly, and the heating flow path is connected between the liquid supply flow path and the heat exchange device. When the heat exchange device is connected to the liquid supply flow path through the heating flow path, the outlet of the heating flow path can be connected to the inlet of the three-way valve. A first outlet of the three-way valve can be connected to the inlet of the first heat exchange flow path, and a second outlet of the three-way valve can be connected to the liquid discharge flow path through a branch flow path. In this way, water heated by the heating flow path can enter the heat exchange flow path through the first outlet and be discharged from the liquid discharge flow path after heat exchange cooling, or can be directly discharged from the liquid discharge flow path through the second outlet and the branch flow path without passing through the heat exchange device. In this way, on the one hand, the water heated by the heating flow path can be directly discharged from the liquid discharge flow path through the branch flow path. On the other hand, the inlet and second outlet of the three-way valve can be disconnected and the inlet of the three-way valve can be connected to the first outlet. In this way, the water heated by the heating flow path can directly enter the heat exchange device and be discharged after heat exchange with the first heat exchange flow path. By providing a three-way valve, water heated by the heating flow path can be directly discharged without cooling to provide relatively high temperature water, such as hot water, and at the same time, water heated by the heating flow path can be cooled and then discharged to provide low temperature liquid at a temperature desired by the user. The installation of a three-way valve enables switching between the hot water provision function and the hot water provision function, thereby making switching between the hot water stage and the hot water stage more convenient.

[0039] The branch flow path here may be incorporated into a heat exchange device so as to become part of the heat exchange device, in which case heat exchange cooling of a liquid such as water can be performed through a heat exchange device having three flow paths.

[0040] The liquid dispensing assembly further includes a liquid dispensing nozzle connected to the outlet of the liquid dispensing channel. The provision of the liquid dispensing nozzle allows the hot water dispensing position, hot water dispensing height, etc. of the product to be adjusted, thereby making it more convenient for the user to receive liquids such as water.

[0041] In one possible design, the first heat exchange flow path is a tortuous flow path with reciprocating bends and / or the second heat exchange flow path is a tortuous flow path with reciprocating bends.

[0042] In this design, the first heat exchange passage and / or the second heat exchange passage may be configured to be a curved passage with a reciprocating bend, thereby extending the length of the first heat exchange passage and / or the second heat exchange passage and improving the heat exchange effect of the heat exchange device. In one possible design, the curved passage is a serpentine passage, or the curved passage is made up of a plurality of S-shaped passages connected to each other end to end, or the curved passage is made up of a plurality of N-shaped passages connected to each other end to end.

[0043] In one possible design, the inlet of the first heat exchange passage and the inlet of the second heat exchange passage are located on the same side of the heat exchange device, and the outlet of the first heat exchange passage and the outlet of the second heat exchange passage are located on the same side of the heat exchange device.

[0044] In this design, the temperature at the inlet of the first heat exchange passage is lower than the temperature at the outlet of the first heat exchange passage, i.e., the temperature gradually increases from the inlet to the outlet of the first heat exchange passage, so the heat exchange efficiency gradually decreases, and the temperature at the inlet of the second heat exchange passage is higher than the temperature at the outlet of the second heat exchange passage. Therefore, the inlet of the first heat exchange passage and the inlet of the second heat exchange passage may be located on the same side of the heat exchange device, for example, both on the right side. At the same time, the outlet of the first heat exchange passage and the outlet of the second heat exchange passage may be located on the same side of the heat exchange device, for example, both on the left side. This allows the flow directions of the liquid in the first heat exchange passage and the second heat exchange passage to be aligned, i.e., the inlet direction of the cooling liquid and the inlet direction of the hot water in the second heat exchange passage to be aligned, and the outlet direction of the cooling liquid and the outlet direction of the hot water in the second heat exchange passage to be aligned. With this arrangement, the coldest cooling liquid can exchange heat with the hottest hot water, thereby increasing the heat exchange rate and cooling speed and therefore improving the heat exchange cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage and the second heat exchange passage do not coincide, the liquid at the inlet of the second heat exchange passage will exchange heat with the liquid at the outlet of the first heat exchange passage, and the liquid at the outlet of the second heat exchange passage will exchange heat with the liquid at the inlet of the first heat exchange passage.With this installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0045] In one possible design, the heat exchange device includes an outer casing and a heat conductive partition wall disposed within the outer casing, with a first heat exchange passage and a second heat exchange passage disposed on either side of the heat conductive partition wall, the outer casing having a first inlet corresponding to the first heat exchange passage and communicating with the first heat exchange passage, and a first outlet corresponding to the first heat exchange passage, and the outer casing having a second inlet corresponding to the second heat exchange passage and communicating with the second heat exchange passage, and a second outlet corresponding to the second heat exchange passage.

[0046] In this design, the heat exchange device includes an outer casing and a thermally conductive partition wall. The outer casing is used to form a sealed space, and the thermally conductive partition wall is used to divide the interior space of the outer casing into two parts, thereby forming two independent flow paths within the outer casing. Specifically, one of the two flow paths divided by the thermally conductive partition wall can be used as the first heat exchange path and the other as the second heat exchange path. The first and second heat exchange paths in the heat exchange device are separated by the thermally conductive partition wall, thereby making heat transfer between the two paths more convenient and efficient. The structure of the heat exchange device is also relatively simple and easy to process, thereby reducing production costs. The outer casing may have an inlet / outlet corresponding to the first heat exchange path, and another inlet / outlet corresponding to the second heat exchange path. Thus, liquid outside the heat exchange device can enter the first and second heat exchange paths through the corresponding inlets / outlets.

[0047] In one possible design, the outer casing includes a first casing, a second casing attached to the first casing, a thermally conductive partition attached to the connection between the first casing and the second casing, a first sealing ring provided between the thermally conductive partition and the first casing for sealing between the thermally conductive partition and the first casing, and a second sealing ring provided between the thermally conductive partition and the second casing for sealing between the thermally conductive partition and the second casing.

[0048] In this design, a sealed space may be formed between the first and second housings, and two flow paths may be partitioned within the space via a thermally conductive partition. This configuration allows the outer housing of the heat exchanger to be divided into multiple components, thereby simplifying the components and reducing processing difficulty and costs. When installed, the thermally conductive partition may be attached to the connection between the first and second housings, i.e., one portion of the thermally conductive partition may be attached within the first housing, and another portion of the thermally conductive partition may be attached within the second housing. In one possible design, a first sealing ring may be provided between the first housing and the thermally conductive partition to seal the first housing and the thermally conductive partition, and a second sealing ring may be provided between the second housing and the thermally conductive partition to seal the second housing and the thermally conductive partition. By providing the first sealing ring and the second sealing ring, it is possible to prevent water leakage at the connection between the first housing and the second housing.

[0049] In another specific technical means, the outer casing includes a first casing, a second casing attached to the first casing, and a third sealing ring attached to the connection between the first casing and the second casing for sealingly connecting the first casing and the second casing, and the thermally conductive partition is attached within the first casing or the second casing.

[0050] In this design, a sealed space is formed between the first and second housings, and two flow paths may be partitioned within the space by a thermally conductive partition wall. During installation, the thermally conductive partition wall may be installed within either the first or second housing to achieve a seal between the first and second housings, and a third sealing ring may be installed at the connection between the first and second housings. This configuration allows the outer housing of the heat exchanger to be divided into multiple components, thereby simplifying each component and reducing processing difficulty and costs. The installation of the third sealing ring provides a seal between the first and second housings, thereby preventing water leakage at the connection between the first and second housings.

[0051] In one possible design, the first inlet and the second inlet are located on the same side of the housing, and the first outlet and the second outlet are located on the same side of the housing.

[0052] In this design, the first inlet and second inlet are located on the same side of the outer casing, and the first outlet and second outlet are located on the same side of the outer casing, which ensures that the liquid flow directions in the first and second heat exchange channels are aligned, i.e., the inlet direction of the coolant is aligned with the inlet direction of the hot water in the second heat exchange channel, and the outlet direction of the coolant is aligned with the outlet direction of the hot water in the second heat exchange channel. This allows the coldest coolant to exchange heat with the hottest hot water, which increases the cooling speed and therefore improves the cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage and the second heat exchange passage do not coincide, the liquid at the inlet of the second heat exchange passage will exchange heat with the liquid at the outlet of the first heat exchange passage, and the liquid at the outlet of the second heat exchange passage will exchange heat with the liquid at the inlet of the first heat exchange passage.With this installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0053] In one possible design, the outer surface of the first housing and / or the second housing is provided with heat dissipation fins.

[0054] In this design, heat can be dissipated through the heat dissipation fins, thereby improving the heat dissipation efficiency of the heat exchange device. The heat dissipation fins can be provided on the first housing, the second housing, or both the first housing and the second housing.

[0055] In one possible design, a plurality of first barrier ribs are provided on an inner surface of the first housing, the plurality of first barrier ribs defining a flow path between the first housing and the thermally conductive partition wall in a tortuous flow path of reciprocating bends.

[0056] In this design, first barrier ribs may be provided on the inner surface of the first housing so that the first or second heat exchange passage can be defined as a curved passage that bends back and forth using the first barrier ribs, thereby extending the length of the first or second heat exchange passage and slowing the flow speed of the liquid in the first or second heat exchange passage, thereby improving the heat exchange efficiency and cooling effect. The first barrier ribs are provided along the transverse direction of the first heat exchange passage, and multiple first barrier ribs are arranged at intervals along the axial direction so that the first heat exchange passage can be divided into multiple sections along the axial direction. Gaps may be provided in the first barrier ribs, or at the connection between the first barrier rib and the thermally conductive partition wall, or at the connection between the first barrier rib and the first housing, so that spaces before and after each first barrier rib can communicate with each other.

[0057] In one possible design, a plurality of second barrier ribs are provided on the inner surface of the second housing, and the plurality of second barrier ribs define a flow path between the second housing and the thermally conductive partition wall into a tortuous flow path of reciprocating bends.

[0058] In this design, second barrier ribs may be provided on the inner surface of the second housing to define the first or second heat exchange passage as a curved passage that bends back and forth using the second barrier ribs, thereby extending the length of the first or second heat exchange passage and slowing the flow speed of the liquid in the first or second heat exchange passage, thereby improving the heat exchange efficiency and cooling effect. The second barrier ribs are provided along the transverse direction of the first heat exchange passage, and multiple second barrier ribs are arranged at intervals along the axial direction, thereby dividing the first heat exchange passage into multiple sections along the axial direction. Gaps may be provided in the second barrier ribs, or at the connection between the second barrier rib and the thermally conductive partition wall, or at the connection between the second barrier rib and the second housing, to allow communication between the spaces before and after each second barrier rib.

[0059] In one possible design, the liquid treatment device further includes a liquid supply tank connected to the liquid supply line and a fourth pumping device disposed in the liquid supply line or the heating line.

[0060] In this design, the liquid supply passage may be connected to the user's home water pipe, allowing water to be supplied directly through the user's home water pipe, but in one possible design, a liquid supply tank may be provided to supply water to the liquid supply passage, allowing water storage and therefore the product to be located far from the water pipe, making the product's usage and installation location more flexible and convenient. At the same time, a fourth pumping device may be provided in the liquid supply passage or the heating passage to control the water flow rate into the heating passage via the fourth pumping device, thereby enabling control of the hot water temperature.

[0061] In one possible design, the heat exchange device includes a cooling device, the cooling device including a cooling box and a cooling liquid provided in the cooling box, and at least a portion of the liquid discharge flow path is installed in the cooling liquid, or the heat exchange device is an air cooling device provided corresponding to the liquid discharge flow path.

[0062] In this design, a cooling device may be provided, a cooling liquid may be provided in the cooling device, and a part or all of the liquid discharge passage may be installed in the cooling liquid, so that the liquid in the liquid discharge passage can be cooled through the cooling liquid, where the cooling liquid may be water, or of course, the cooling liquid may be made of another liquid with good heat absorption. In another design, the heat exchange device may be provided as an air cooling device, so that the liquid discharge passage can be cooled through the air cooling device.

[0063] To achieve multiple cooling, the liquid in the liquid discharge flow path may be cooled by using a cooling device consisting of the above-mentioned heat exchanger, air cooling device, and cooling box with cooling liquid in combination, or, of course, cooling may be performed by adopting only one of the above-mentioned cooling methods.

[0064] In one possible design, the liquid treatment device further includes a circuit board assembly, which may include a power board for providing electrical power and a control board for controlling operation of the product.

[0065] Furthermore, the liquid treatment device includes a housing case, a heating assembly mounted within the housing case, a circuit board assembly, a liquid supply assembly, a liquid supply tank, etc., and the housing case may specifically consist of a base and a case lid.

[0066] In one possible design, the liquid treatment device may specifically be a product such as a quick-heating electric kettle, coffee pot, soy milk maker, juicer, etc. Of course, the liquid treatment device may also be other products than a quick-heating electric kettle, coffee pot, soy milk maker, juicer, such as a mixer, health pot, etc.

[0067] A technical solution of a second aspect of the present application provides a heat exchange device for use in a liquid treatment device, the heat exchange device including a first heat exchange passage and a second heat exchange passage, the first heat exchange passage being capable of exchanging heat with the second heat exchange passage to cool a liquid in the second heat exchange passage.

[0068] The heat exchange device according to the present application can be used in a liquid treatment device, and specifically, the heat exchange device incorporates a first heat exchange flow path and a second heat exchange flow path, the second heat exchange flow path being connected between a heating assembly and a liquid discharge assembly, and the first heat exchange flow path may specifically be used to exchange heat with the second heat exchange flow path so as to heat-cool the liquid in the second heat exchange flow path.

[0069] In this design, the liquid treatment device includes a liquid supply assembly, a liquid discharge assembly, and a heating assembly connected between the liquid supply assembly and the liquid discharge assembly, and a second heat exchange flow path is connected between the heating assembly and the liquid discharge assembly.

[0070] This structure allows liquid, such as water, heated by the heating assembly to be cooled by heat exchange with the first heat exchange path in the second heat exchange path before being discharged through the liquid discharge assembly. The temperature of the high-temperature liquid heated by the heating assembly when it flows through the second heat exchange path is higher than the temperature of the coolant in the first heat exchange path. This allows the first heat exchange path to continuously absorb heat from the liquid, such as water, in the second heat exchange path to achieve heat exchange between the first and second heat exchange paths. This allows the liquid, such as water, in the second heat exchange path to be cooled through heat exchange between the first and second heat exchange paths. This structure allows the liquid, such as water, heated by the heating device to be cooled using heat exchange principles. This cooling method is simple and easy to implement, thereby simplifying the product structure and reducing product costs. Of course, other cooling methods may also be used, such as air cooling using an electric fan. In this case, the heat exchange device may be an air-cooling device.

[0071] In one possible design, the heat exchange device further comprises a reservoir tank connected to the inlet of the first heat exchange channel and to the outlet of the first heat exchange channel to form a refrigeration circulation circuit.

[0072] In this design, a liquid storage tank may be additionally provided to form a circuit with the first heat exchange flow path via the liquid storage tank, thereby constantly providing cooling power to cool the liquid, such as water, in the liquid discharge flow path. This structure allows the cooling circuit to be independent of the liquid flow path consisting of the liquid supply assembly, heating assembly, and liquid discharge assembly, thereby allowing the cooling circuit and the liquid flow path to operate independently, thereby allowing the cooling circuit to be turned on or off independently. In this way, whether to turn on the cooling circuit can be determined according to actual demand when the liquid treatment device is operating. When the cooling circuit is not turned on, heated water can be directly discharged at a corresponding temperature, such as boiling water. When the cooling circuit is turned on, water can first be heated to a relatively high temperature, such as boiling, and then cooled to a relatively low temperature before being discharged. This structure allows the product to directly heat water and discharge it, or to first heat and cool water before discharging it, thereby expanding product functions and realizing product diversification, thereby enabling the product to better meet various user needs.

[0073] Additionally, the liquid treatment device further includes a temperature collection element disposed within the reservoir tank for collecting the temperature of the liquid within the reservoir tank.

[0074] In this design, a temperature collection element is used to collect the temperature of the liquid in the reservoir tank so that the flow rate of the cooling liquid in the first heat exchange flow path can be controlled based on the temperature of the liquid in the reservoir tank and further the cooling intensity can be controlled.

[0075] In one possible design, the inlet of the first heat exchange passage and the inlet of the second heat exchange passage are located on the same side of the heat exchange device, and the outlet of the first heat exchange passage and the outlet of the second heat exchange passage are located on the same side of the heat exchange device.

[0076] In this design, the temperature at the inlet of the first heat exchange passage is lower than the temperature at the outlet of the first heat exchange passage, i.e., the temperature gradually increases from the inlet to the outlet of the first heat exchange passage, so the heat exchange efficiency gradually decreases, and the temperature at the inlet of the second heat exchange passage is higher than the temperature at the outlet of the second heat exchange passage. Therefore, the inlet of the first heat exchange passage and the inlet of the second heat exchange passage may be located on the same side of the heat exchange device, for example, both on the right side. At the same time, the outlet of the first heat exchange passage and the outlet of the second heat exchange passage may be located on the same side of the heat exchange device, for example, both on the left side. In this way, the flow directions of the liquid in the first heat exchange passage and the second heat exchange passage are aligned, i.e., the inlet direction of the cooling liquid is aligned with the inlet direction of the hot water in the second heat exchange passage, and the outlet direction of the cooling liquid is also aligned with the outlet direction of the hot water in the second heat exchange passage. With this arrangement, the coldest cooling liquid can exchange heat with the hottest hot water, thereby increasing the heat exchange rate and cooling speed and thereby improving the heat exchange cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage and the second heat exchange passage do not coincide, the liquid at the inlet of the second heat exchange passage will exchange heat with the liquid at the outlet of the first heat exchange passage, and the liquid at the outlet of the second heat exchange passage will exchange heat with the liquid at the inlet of the first heat exchange passage.With this installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0077] In one possible design, the heat exchange device includes an outer casing and a heat conductive partition wall disposed within the outer casing, with a first heat exchange passage and a second heat exchange passage disposed on either side of the heat conductive partition wall, the outer casing having a first inlet corresponding to the first heat exchange passage and communicating with the first heat exchange passage, and a first outlet corresponding to the first heat exchange passage, and the outer casing having a second inlet corresponding to the second heat exchange passage and communicating with the second heat exchange passage, and a second outlet corresponding to the second heat exchange passage.

[0078] In this design, the heat exchange device includes an outer casing and a thermally conductive partition wall. The outer casing is used to form a sealed space, and the thermally conductive partition wall is used to divide the interior space of the outer casing into two parts, thereby forming two independent flow paths within the outer casing. Specifically, one of the two flow paths divided by the thermally conductive partition wall can be used as the first heat exchange path and the other as the second heat exchange path. The first and second heat exchange paths in the heat exchange device are separated by the thermally conductive partition wall, thereby making heat transfer between the two paths more convenient and efficient. The structure of the heat exchange device is also relatively simple and easy to process, thereby reducing production costs. The outer casing may have an inlet / outlet corresponding to the first heat exchange path, and another inlet / outlet corresponding to the second heat exchange path, allowing liquid outside the heat exchange device to enter the first and second heat exchange paths through the corresponding inlets / outlets.

[0079] In one possible design, the outer casing includes a first casing, a second casing attached to the first casing, a thermally conductive partition attached to the connection between the first casing and the second casing, a first sealing ring provided between the thermally conductive partition and the first casing for sealing between the thermally conductive partition and the first casing, and a second sealing ring provided between the thermally conductive partition and the second casing for sealing between the thermally conductive partition and the second casing.

[0080] In this design, a sealed space may be formed between the first and second housings, and two flow paths may be partitioned within the space via a thermally conductive partition. This configuration allows the outer housing of the heat exchanger to be divided into multiple components, thereby simplifying the components and reducing processing difficulty and costs. When installed, the thermally conductive partition may be attached to the connection between the first and second housings, i.e., one portion of the thermally conductive partition may be attached within the first housing, and another portion of the thermally conductive partition may be attached within the second housing. In one possible design, a first sealing ring may be provided between the first housing and the thermally conductive partition to seal the first housing and the thermally conductive partition, and a second sealing ring may be provided between the second housing and the thermally conductive partition to seal the second housing and the thermally conductive partition. By providing the first sealing ring and the second sealing ring, it is possible to prevent water leakage at the connection between the first housing and the second housing.

[0081] In another specific technical means, the outer casing includes a first casing, a second casing attached to the first casing, and a third sealing ring attached to the connection between the first casing and the second casing for sealingly connecting the first casing and the second casing, and the thermally conductive partition is attached within the first casing or the second casing.

[0082] In this design, a sealed space is formed between the first and second housings, and two flow paths can be partitioned within the space using a thermally conductive partition wall. During installation, the thermally conductive partition wall can be installed within either the first or second housing to achieve a seal between the first and second housings, and a third sealing ring can be installed at the connection between the first and second housings. This configuration allows the outer housing of the heat exchanger to be divided into multiple components, thereby simplifying each component and reducing processing difficulty and costs. The installation of the third sealing ring provides a seal between the first and second housings, thereby preventing water leakage at the connection between the first and second housings.

[0083] In one possible design, the first inlet and the second inlet are located on the same side of the housing, and the first outlet and the second outlet are located on the same side of the housing.

[0084] In this design, the first inlet and second inlet are located on the same side of the outer casing, and the first outlet and second outlet are located on the same side of the outer casing, which ensures that the liquid flow directions in the first and second heat exchange channels are aligned, i.e., the inlet direction of the coolant is aligned with the inlet direction of the hot water in the second heat exchange channel, and the outlet direction of the coolant is aligned with the outlet direction of the hot water in the second heat exchange channel. This allows the coldest coolant to exchange heat with the hottest hot water, which increases the cooling speed and therefore improves the cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage and the second heat exchange passage do not coincide, the liquid at the inlet of the second heat exchange passage will exchange heat with the liquid at the outlet of the first heat exchange passage, and the liquid at the outlet of the second heat exchange passage will exchange heat with the liquid at the inlet of the first heat exchange passage.With this installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0085] In one possible design, the outer surface of the first housing and / or the second housing is provided with heat dissipation fins.

[0086] In this design, heat can be dissipated through the heat dissipation fins, thereby improving the heat dissipation efficiency of the heat exchange device. The heat dissipation fins can be provided on the first housing, the second housing, or both the first housing and the second housing.

[0087] In one possible design, a plurality of first barrier ribs are provided on an inner surface of the first housing, the plurality of first barrier ribs defining a flow path between the first housing and the thermally conductive partition wall in a tortuous flow path of reciprocating bends.

[0088] In this design, first barrier ribs may be provided on the inner surface of the first housing to define the first or second heat exchange passage as a curved passage that bends back and forth using the first barrier ribs, thereby extending the length of the first or second heat exchange passage and slowing the flow speed of the liquid in the first or second heat exchange passage, thereby improving the heat exchange efficiency and cooling effect. The first barrier ribs are provided along the transverse direction of the first heat exchange passage, and multiple first barrier ribs are arranged at intervals along the axial direction. In this way, the first heat exchange passage can be divided into multiple sections along the axial direction, and gaps may be provided in the first barrier ribs, or at the connection between the first barrier rib and the thermally conductive partition wall, or at the connection between the first barrier rib and the first housing, to allow communication between the spaces before and after each first barrier rib.

[0089] In one possible design, a plurality of second barrier ribs are provided on the inner surface of the second housing, and the plurality of second barrier ribs define a flow path between the second housing and the thermally conductive partition wall into a tortuous flow path of reciprocating bends.

[0090] In this design, second barrier ribs may be provided on the inner surface of the second housing to define the first or second heat exchange passage as a curved passage that bends back and forth using the second barrier ribs, thereby extending the length of the first or second heat exchange passage and slowing the flow speed of the liquid in the first or second heat exchange passage, thereby improving the heat exchange efficiency and cooling effect. The second barrier ribs are provided along the transverse direction of the first heat exchange passage, and multiple second barrier ribs are arranged at intervals along the axial direction. In this way, the first heat exchange passage can be divided into multiple sections along the axial direction, and gaps may be provided in the second barrier ribs, or at the connection between the second barrier rib and the thermally conductive partition wall, or at the connection between the second barrier rib and the second housing, to allow communication between the spaces before and after each second barrier rib.

[0091] A technical solution of a third aspect of the present application provides a heat exchange box for use in a liquid heating appliance, the heat exchange box having a box portion and a heat conductive partition wall, a first heat exchange flow path and a second heat exchange flow path surrounded by the box portion and the heat conductive partition wall, the first heat exchange flow path and the second heat exchange flow path separated by the heat conductive partition wall, and configured to provide heat conduction between a medium in the second heat exchange flow path and a medium in the first heat exchange flow path.

[0092] The heat exchange box according to the present invention has a first heat exchange passage and a second heat exchange passage surrounded by a box part and a heat conductive partition wall, and the first heat exchange passage and the second heat exchange passage are separated by the heat conductive partition wall. As such, the structure of the heat exchange box is simple, the layout is reasonable, and the product is more integrated. Heat exchange between the cold and hot fluids is performed through the heat conductive partition wall, so that the hot fluid can be quickly cooled to an appropriate temperature and the cold fluid can be preheated, thereby reducing the energy required to heat the cold fluid to boiling when heating it. This reduces energy consumption, and the high thermal conductivity of the thermal conductive partition can be used to accelerate the heat transfer rate between the hot and cold fluids, shorten the heat exchange time, and improve the heat exchange effect of the heat exchange box. At the same time, the first heat exchange passage and the second heat exchange passage are separated by the thermal conductive partition, forming a partition-type heat exchange between the hot and cold fluids, thereby realizing heat exchange between the medium in the second heat exchange passage and the medium in the first heat exchange passage, without mixing, ensuring that the hot fluid is not contaminated by the cold fluid, and improving the safety of the hot fluid.

[0093] In addition, the heat exchange box in the above embodiment of the present application may have the following additional technical features.

[0094] In one possible design, the box portion includes a box lid that is placed over the thermally conductive partition wall and hermetically connected to the thermally conductive partition wall, and the first heat exchange flow path or the second heat exchange flow path is surrounded by the box lid and the thermally conductive partition wall.

[0095] In this design, the box lid is placed over the thermal conductive partition wall and hermetically connected to the thermal conductive partition wall. First, the box lid is placed over the thermal conductive partition wall to form the first heat exchange flow path or the second heat exchange flow path. In this way, under the same dimensional specifications, it is advantageous to increase the heat conduction area and improve the heat exchange effect of the heat exchange box. In addition, when the box lid is hermetically connected to the thermal conductive partition wall, it prevents liquid leakage from the first heat exchange flow path or the second heat exchange flow path and mixing between the medium in the first heat exchange flow path and the medium in the second heat exchange flow path, thereby ensuring that the hot fluid is not contaminated by the cold fluid and improving the safety and hygiene of the hot fluid.

[0096] In one possible design, the box lid has a pocket, which is a chamber body with an opening at one end, with flow-guiding ribs distributed within the pocket, and a heat-conducting partition covering the opening of the pocket.

[0097] In this design, the box lid has a pocket, which is advantageous for increasing the volume of the first or second heat exchange passage and improving the heat exchange efficiency. In addition, flow guide ribs are distributed within the pocket, which guide the fluid, thereby extending the fluid flow path within the first or second heat exchange passage, reducing the fluid flow speed, and making the heat exchange between the hot and cold fluids more efficient.

[0098] In one possible design, the box part includes two box lids, between which a thermally conductive partition is distributed, and the two box lids are connected and gripped by the thermally conductive partition, or at least one of the two box lids is connected to the thermally conductive partition.

[0099] As can be seen, in this design, the two box lids are connected and gripped by the thermal conductive partition, or at least one of the two box lids is connected to the thermal conductive partition, so that the first heat exchange passage is surrounded by one of the two box lids and the thermal conductive partition, and the second heat exchange passage is surrounded by the other of the two box lids and the thermal conductive partition, and the two box lids are connected, which also realizes the installation and fixing of the thermal conductive partition, making the product structure simple and easy to assemble, which is beneficial to improving the assembly speed and shortening the installation time.

[0100] In one possible design, one of the two box lids is provided with a fitting portion and the other is provided with a receiving portion, the fitting portion being fitted into the receiving portion to position the two box lids, and / or one of the two box lids is provided with a locking device and the other is provided with a locking groove, the locking device being locked into the locking groove, and / or one of the two box lids is provided with a protrusion, the protrusion is provided with a first hole, the other one of the two box lids is provided with a second hole, the second hole is provided corresponding to the first hole, and connecting members are drilled into the first hole and the second hole to lock the two box lids together.

[0101] In this design, the fitting portion is fitted into the accommodating portion, which has the advantage of facilitating assembly operations and facilitating quick and easy positioning and pre-fixing between the two box lids, improving the ease of assembly of the product. Furthermore, the fitting portion is fitted into the accommodating portion for positioning, which increases the connection accuracy between the two box lids and is advantageous for improving the sealing of the second heat exchange passage and the first heat exchange passage.

[0102] One of the two box lids is provided with a locking device, and the other is provided with a locking groove, and the locking device is locked into the locking groove. This has the advantages of simple structure and convenient installation, which can improve the assembly efficiency of the product and at the same time effectively ensure the connection reliability of the two box lids.

[0103] The connecting member is drilled into the first hole and the second hole to lock the two box lids together, which has a simple structure, is convenient to install, ensures the connection reliability of the two box lids, and reduces the cost of the product.

[0104] In one possible design, the box section includes a box body, the heat exchange box having a plurality of thermally conductive partition walls distributed at intervals, the box body being sealedly connected to each of two adjacent thermally conductive partition walls, and together with the two adjacent thermally conductive partition walls being surrounded by the first heat exchange flow path or the second heat exchange flow path.

[0105] In this design, the box body is respectively sealed and connected to two adjacent heat conduction partitions, and is surrounded by the first heat exchange passage or the second heat exchange passage together with the two adjacent heat conduction partitions. The structure is relatively simple, the assembly is relatively convenient, and it is advantageous for reducing production costs. Furthermore, the two heat conduction partitions transfer heat from both sides, which further improves the heat exchange effect of the medium in the first heat exchange passage or the medium in the second heat exchange passage.

[0106] In one possible design, the box body is a ring-shaped body with open ends, the ring-shaped body is provided with flow guide ribs, and the flow guide ribs on the ring-shaped body are distributed in the area surrounded by the ring-shaped body, and heat conductive partitions are respectively arranged on both sides of the ring-shaped body, and the heat conductive partitions on both sides cover the openings at both ends of the ring-shaped body.

[0107] In this design, the box body is an annular body with both ends penetrated, which is advantageous for obtaining a larger volume with the same dimensions, and the annular body is provided with flow guide ribs. By guiding the fluid through the flow guide ribs, the flow path of the fluid in the first heat exchange passage or the second heat exchange passage is extended, the fluid flow speed is reduced, and the heat exchange effect is improved.

[0108] In one possible design, the box part includes two box lids and at least one box body, with a thermally conductive partition and a box body distributed between the two box lids, and the two box lids are connected and gripped to the thermally conductive partition and the box body, or at least one of the two box lids is connected to the thermally conductive partition and the box body.

[0109] In this design, the two box lids are connected and gripped to the thermal conductive partition and the box body, or at least one of the two box lids is connected to the thermal conductive partition and the box body, which increases the volume of the first heat exchange passage or the second heat exchange passage through the box body and uses more cold fluid to exchange heat with the hot fluid, thereby ensuring that the hot fluid is sufficiently heat exchanged and further improving the heat exchange efficiency.

[0110] In one possible design, an insert coupling positioning is formed between adjacent box lids and box bodies or between adjacent box bodies, and / or the box bodies are provided with through holes for the passage of connecting members.

[0111] In this design, an insert-fit joint positioning is formed between adjacent box lids and box bodies, or between adjacent box bodies and box bodies, which has the advantage of facilitating assembly operations and facilitating quick and easy positioning and pre-fixing between the two box lids, improving the ease of assembly of the product, and positioning is achieved by inserting the fitting portion into the receiving portion, which improves the joint precision between the two box lids and box bodies and is advantageous to improving the sealing of the first heat exchange channel and the second heat exchange channel.

[0112] The provision of a through hole in the box body for the connection member to pass through allows the two box lids to be connected and attached, while also connecting and fixing the box body, thereby enhancing the connection stability and assembly accuracy of the three components (the two box lids and the box body), reducing the risk of liquid leakage, and further improving the reliability and sealing performance of the product.

[0113] In one possible design, the heat exchanger box has a sealing ring, which is abutted against the box part and the thermal conductive partition wall and is hermetically connected to the box part and the thermal conductive partition wall, or a sealing layer is formed between the box part and the thermal conductive partition wall, and the sealing layer adhesively fixes the box part and the thermal conductive partition wall.

[0114] In this design, the sealing ring abuts against the box part and the heat conductive partition wall and is sealed and connected to the box part and the heat conductive partition wall, which further ensures sealing between the box part and the heat conductive partition wall, makes it less likely for leakage to occur between the box part and the heat conductive partition wall, and effectively prevents turbulence between the medium in the first heat exchange passage and the medium in the second heat exchange passage.

[0115] The sealing layer formed between the box part and the thermal conductive partition ensures the sealing between the box part and the thermal conductive partition, and also serves to adhesively fix the box part and the thermal conductive partition, thereby preventing misalignment between the box part and the thermal conductive partition and improving the reliability of the connection between the box part and the thermal conductive partition.

[0116] In one possible design, a recessed groove is provided in at least one of the box portion and the thermally conductive partition, and at least a portion of the sealing ring or sealing layer is fitted into the recessed groove, and / or the sealing ring or sealing layer is arranged around the edge of the thermally conductive partition.

[0117] In this design, at least a portion of the sealing ring or sealing layer is fitted into the recessed groove, and the recessed groove provides an attachment portion for the sealing ring or sealing layer, thereby preventing the sealing ring or sealing layer from moving and avoiding the problem of poor sealing caused by misalignment of the sealing ring or sealing layer. This improves the positional accuracy of the sealing ring or sealing layer, thereby improving the accuracy of the sealing connection between the sealing ring or sealing layer and the box part and the thermal conduction partition, and further improving the reliability of the sealing.

[0118] The sealing ring or sealing layer is arranged around the edge of the thermal conduction partition wall, which ensures the reliability of the seal and prevents the sealing ring or sealing layer from contaminating the medium in the first heat exchange flow path or the medium in the second heat exchange flow path, thereby improving safety and hygiene.

[0119] In one possible design, a turbulent flow structure is configured in at least one of the box section of the heat exchange box and the heat conduction partition.

[0120] In this design, the turbulent structure increases the turbulence of the fluid and slows down the fluid velocity, thereby increasing the convective heat exchange coefficient between the fluid and the heat conducting partition and increasing the heat exchange amount. The turbulent structure can also disturb the medium, making the temperature inside the first heat exchange channel and the second heat exchange channel more uniform and ensuring a better heat exchange effect.

[0121] In one possible design, the thermally conductive barrier is configured with protruding and / or recessed structures, which are formed as turbulent structures on the thermally conductive barrier.

[0122] In this design, the heat conduction partition wall has a convex structure and / or a concave structure, which simplifies the structure of the heat conduction partition wall, facilitates processing, and is advantageous in reducing costs. Furthermore, the convex structure and / or the concave structure increase the surface area of ​​the heat conduction partition wall, thereby further increasing the heat conduction area of ​​the two medium flow paths and improving heat exchange.

[0123] In one possible design, the heat exchange box is divided into multiple spaces via thermally conductive partitions, and flow guide ribs are distributed within the spaces, and the flow guide ribs define curved flow paths within the spaces.

[0124] In this design, the flow guide ribs divide a curved flow path within the space, which extends the flow path of the fluid in the first heat exchange flow path or the second heat exchange flow path, reduces the fluid flow speed, makes the heat exchange between the medium in the first heat exchange flow path and the medium in the second heat exchange flow path more complete, and improves the heat exchange effect.

[0125] In one possible design, the flow guide rib is provided with one or more first turbulence ribs, and the first turbulence ribs protrude into the flow path, and / or there is a gap between the flow guide rib and the heat conduction partition, and / or the box portion of the heat exchanger box has a sealing barrier, the space is surrounded by the sealing barrier and the heat conduction partition, and one or more second turbulence ribs are provided on the sealing barrier, and the second turbulence ribs protrude into the flow path, and / or the flow guide ribs define a serpentine flow path within the space.

[0126] In this design, the provision of one or more first turbulence ribs on the flow guide ribs further reduces the flow velocity of the fluid while guiding the flow, thereby improving the heat exchange effect.

[0127] Providing one or more second turbulence ribs on the sealing barrier not only guides the flow but also further reduces the flow velocity of the fluid, improving the heat exchange effect.

[0128] The flow guide ribs divide the serpentine flow path within the space, further extending the flow path of the fluid in the first heat exchange flow path or the second heat exchange flow path, making the heat exchange between the medium in the first heat exchange flow path and the medium in the second heat exchange flow path more complete and improving the heat exchange effect.

[0129] In one possible design, the first heat exchange passage and the second heat exchange passage on both sides of the heat conduction partition are arranged opposite to each other, or the first heat exchange passage and the second heat exchange passage on both sides of the heat conduction partition are arranged in a mixed flow distribution.

[0130] In this design, the fact that the first heat exchange passage and the second heat exchange passage on both sides of the heat conduction partition are arranged in opposite positions can also be understood as the first heat exchange passage and the second heat exchange passage corresponding to each other in the projection direction, which makes the structural layout inside the heat exchange box more reasonable and is advantageous for making full use of the first heat exchange passage and the second heat exchange passage, and the heat conduction area between the first heat exchange passage and the second heat exchange passage is larger, making the heat exchange more efficient.

[0131] The mixed flow distribution between the first heat exchange passage and the second heat exchange passage increases the heat exchange efficiency between the first heat exchange passage and the second heat exchange passage.

[0132] In another embodiment, parallel flow heat exchange may be provided between the first and second heat exchange passages.

[0133] In any one of the above technical means, the heat exchange box has a first communication port, a second communication port, a third communication port, and a fourth communication port, the second heat exchange flow path connects the first communication port and the second communication port, the first heat exchange flow path connects the third communication port and the fourth communication port, the first communication port and the third communication port are positioned opposite each other, and / or the second communication port and the fourth communication port are positioned opposite each other.

[0134] In any one of the above technical solutions, the heat-conducting partition is a metal member, and / or the box part of the heat exchanger box is a heat-conducting member, and / or fins are provided on the surface of the box part of the heat exchanger box.

[0135] In this embodiment, the thermally conductive partition wall is a metal member, for example, an aluminum plate or a stainless steel plate. Thus, the thermally conductive partition wall has the advantages of good thermal conductivity and low cost.

[0136] The box part of the heat exchange box is a heat-conducting member, which allows the heat exchange box to exchange heat with the outside and is advantageous in further reducing the temperature of the heat exchange box, thereby allowing the thermal fluid to dissipate heat more quickly and improving the heat exchange efficiency.

[0137] By providing fins on the surface of the box portion of the heat exchange box, the heat exchange capacity between the heat exchange box and the outside is further improved.

[0138] A fourth aspect of the technical means of the present application provides a liquid heating appliance including a liquid discharge nozzle, a liquid supply tank, and a water channel system connected to the liquid discharge nozzle and the liquid supply tank, and the heat exchange box in any one of the above technical means is formed as part of the water channel system.

[0139] The liquid heating appliance according to the above-mentioned embodiment of the present application has all of the above-mentioned beneficial technical effects by providing a heat exchange box in any one of the above-mentioned technical means, and therefore further explanation will be omitted here.

[0140] In one possible design, the waterway system has one heat exchange box or a plurality of heat exchange boxes, with first heat exchange passages of the plurality of heat exchange boxes connected in series and second heat exchange passages of the plurality of heat exchange boxes connected in series.

[0141] In this design, the waterway system has one heat exchange box, which not only ensures the reliability of heat exchange of the thermal fluid, but also simplifies the structure of the waterway system, which is advantageous for reducing the difficulty of product assembly and realizing a more compact product.

[0142] The first heat exchange flow paths of multiple heat exchange boxes are connected in series, and the second heat exchange flow paths of multiple heat exchange boxes are connected in series, so that by adding heat exchange boxes, the fluid flow path is extended and the cold and hot fluids are efficiently heat exchanged.

[0143] In one possible design, the position of at least a part of the waterway system is higher than the maximum water level of the supply tank.

[0144] In this design, the position of at least a part of the waterway system is higher than the highest water level position of the liquid supply tank, which effectively prevents water from directly flowing out of the liquid discharge nozzle due to the connector principle, and improves the reliability of the product.

[0145] In one possible design, the position of at least one of the first communication port, the second communication port, the third communication port and the fourth communication port of the heat exchange box is higher than the highest water level position of the supply liquid tank, and / or the heat exchange box is arranged vertically, horizontally or diagonally.

[0146] In this design, by controlling the positions of the first communication port, the second communication port, the third communication port and / or the fourth communication port of the heat exchange box, it is easy to ensure that they are higher than the highest water level position of the liquid supply tank, making assembly easier and reducing the assembly difficulty, and effectively preventing water from directly flowing out of the liquid discharge nozzle due to the connector principle, thereby improving product reliability.

[0147] In one possible design, the water channel system further includes a heating assembly and a water distribution box, the water distribution box being connected to the liquid supply tank and the second heat exchange flow path of the heat exchange box, and the liquid supply tank supplying water to the second heat exchange flow path via the water distribution box, the water distribution box being connected to the second heat exchange flow path and the heating assembly, and the second heat exchange flow path supplying water to the heating assembly via the water distribution box, and the first heat exchange flow path being connected to the heating assembly and the liquid discharge nozzle.

[0148] In this embodiment, the water distribution box is connected to the liquid supply tank and the second heat exchange passage of the heat exchange box, and the cold water in the liquid supply tank is discharged into the second heat exchange passage through the water distribution box, and the cold water is sufficiently heat-exchanged with the hot water in the first heat exchange passage in the second heat exchange passage, thereby cooling the hot water to an appropriate temperature and preheating the cold water. The water distribution box is connected to the second heat exchange passage and the heating assembly, that is, the water distribution box and the second heat exchange passage form a circulation circuit, and the cold water after heat exchange in the second heat exchange passage flows through the water distribution box to the heating assembly, and the preheated cold water is then fed to the heating assembly. The heating assembly is heated by an assembly, which is advantageous in reducing the power and heating time of the heating assembly and reducing the energy consumption of the heating assembly, making the product more energy-efficient. The first heat exchange flow path is connected to the heating assembly and the liquid discharge nozzle, and the hot water heated by the heating assembly is discharged through the first heat exchange flow path and the liquid discharge nozzle, and simultaneously supplies water to the second heat exchange flow path and the heating assembly through the water distribution box, which receives the circulating water of the second heat exchange flow path. In this way, the piping connection between each component in the water channel system is made easier, and the connecting piping inside the product is made simpler and less messy.

[0149] In one possible design, the water conduit system has a first pump that drives liquid from the water distribution box to the second heat exchange flow path, and / or the water conduit system has a second pump that drives liquid from the water distribution box to the heating assembly, and / or at least a portion of one or more of the water distribution box, heating assembly, first pump, and second pump in the water conduit system is located higher than the maximum water level position of the liquid supply tank.

[0150] In this design, the provision of a first pump to drive the liquid from the water distribution box to the second heat exchange flow path can improve the efficiency and reliability of the fluid flow, avoid the problem of fluid clogging, and ensure the high heat exchange efficiency of the heat exchange box.

[0151] Providing a second pump to drive the liquid from the water box to the heating assembly can improve the efficiency and reliability of the fluid flow, avoiding the risk of fluid clogging and the heating assembly running dry, and improving product safety.

[0152] A fifth aspect of the present application provides a liquid heating appliance, including a waterway system having a liquid discharge nozzle, a heat exchange box, a flow parameter adjusting member, and a heating assembly, a temperature measurement system connected to the waterway system and measuring a temperature relative to the waterway system, and a control assembly connected to the temperature measurement system, the heating assembly, and the flow parameter adjusting member and controlling heating power of the heating assembly and / or liquid flow parameters in the waterway system based on temperature information fed back by the temperature measurement system. The heat exchange box has a first heat exchange passage and a second heat exchange passage, the first heat exchange passage heat exchanges with the second heat exchange passage, the heating assembly has a water inlet and a water outlet, the water inlet is in communication with the first heat exchange passage and the second heat exchange passage is connected to the water outlet and the liquid discharge nozzle, and the flow parameter adjusting member is suitable for adjusting the liquid flow parameters in the waterway system.

[0153] The liquid heating appliance of the present application can have the water heated by the heating assembly and then discharged through a heat exchange process in a heat exchange box, after which it can be discharged from the liquid heating appliance along a liquid discharge nozzle for user use. Through the heat exchange process in the heat exchange box, the liquid heating appliance can provide water at different temperature stages to meet the user's hot water needs of different temperatures. Compared to related technologies that heat water to a specified temperature in a non-boiling stage to provide hot water at multiple temperatures, this design adopts a heat exchange cooling structure after heating, which has a better sterilization effect and can balance the user's hot water temperature needs and food safety needs. Furthermore, the water that has been heat exchanged and heated in the first heat exchange flow path of the heat exchange box can be supplied to the heating assembly, realizing heat recovery of the product and improving the operating energy efficiency of the product. In addition, this structure provides a temperature measurement system for measuring the temperature of the waterway system, and the control assembly timely adjusts the heating power of the heating assembly and / or the liquid flow parameters in the waterway system based on the temperature information of the waterway system, thereby forming a temperature control adjustment for the waterway system. This can improve the stability and accuracy of the hot water temperature of the product, ensure that the actual hot water temperature of the product better meets the hot water temperature demand, and improve the user experience of the product.

[0154] The liquid heating device according to the present application may also have the following additional technical features.

[0155] In one possible design, the temperature measurement system includes a first temperature measurement element that collects the temperature of the water inlet and responds by emitting a corresponding signal based on the collected results, and a control assembly connected to the first temperature measurement element, and the control assembly controls the heating power of the heating assembly and / or the liquid flow parameters of the water inlet based on the signal from at least the first temperature measurement element.

[0156] In this design, the heating assembly may absorb heat-exchanged water from the first heat exchange flow path, so the temperature is relatively high and changes in real time. A first temperature measuring element is provided to collect the water temperature at the water inlet of the heating assembly and control the heating power of the heating assembly and / or the liquid flow parameters of the water inlet (e.g., flow rate, flow velocity, etc.) accordingly. In this way, the compatibility between the heat supply amount of the heating assembly and the heat energy demand can be improved, the sterilization effect of the heating assembly on the liquid can be better guaranteed, for example, the water in the heating assembly can be better heated to boiling, improving food safety, and the heat exchange efficiency in the heat exchange box can be more accurate, thereby realizing the accuracy and stability of the hot water temperature at the liquid discharge nozzle.

[0157] In one possible design, the temperature measurement system includes a second temperature measurement element that collects the temperature of the water outlet and responds by emitting a corresponding signal based on the collected results, and a control assembly connected to the second temperature measurement element that controls the heating power of the heating assembly and / or the liquid flow parameters of the water inlet based on at least the signal from the second temperature measurement element.

[0158] In this design, the heating assembly may absorb heat-exchanged water from the first heat exchange flow path, so the temperature is relatively high and changes in real time. A second temperature measuring element is provided to collect the water temperature at the water outlet of the heating assembly and control the heating power of the heating assembly and / or the liquid flow parameters (e.g., flow rate, flow speed, etc.) of the water inlet accordingly. In this way, the compatibility between the heat supply amount of the heating assembly and the heat energy demand can be improved, the sterilization effect of the heating assembly on the liquid can be better guaranteed, for example, the water in the heating assembly can be better heated to boiling, improving food safety, and the heat exchange efficiency in the heat exchange box can be more accurate, thereby realizing the accuracy and stability of the hot water temperature at the liquid discharge nozzle.

[0159] In one possible design, the control assembly is provided with a first comparator, one input end of which is connected to the output end of the second temperature measuring element to obtain the temperature of the water outlet, the other input end of which is accessed a preset temperature threshold, and when the temperature of the water outlet does not exceed the preset temperature threshold, an output signal of the first comparator is configured to increase the heating power of the heating assembly and / or reduce the flow rate of the water inlet; and / or the control assembly is provided with a second comparator, one input end of which is connected to the output end of the second temperature measuring element to obtain the temperature of the water outlet, the other input end of which is accessed a boiling temperature, and when the temperature of the water outlet is at least the boiling temperature, an output signal of the second comparator is configured to reduce the heating power of the heating assembly and / or increase the flow rate of the water inlet.

[0160] It can be understood that a comparator has two input terminals, and is used to compare signals from the two input terminals and output the comparison result.

[0161] In this design, the first comparator compares the temperature from the water outlet of the second temperature measuring element with a preset temperature threshold, and if the temperature of the water outlet is equal to or lower than the preset temperature threshold, the first comparator issues a signal to trigger an increase in the heating power of the heating assembly and / or triggers the flow parameter adjusting member to reduce the flow rate of the water inlet, so as to correspondingly increase the temperature of the liquid discharged from the heating assembly to better meet the sterilization demand and improve food safety. If the temperature of the water outlet is higher than the preset temperature threshold, the first comparator does not output a signal to maintain the heating power of the heating assembly and / or maintain the flow rate of the water inlet. Of course, if the temperature of the water outlet is higher than the preset temperature threshold, the output signal of the first comparator may be designed to trigger a decrease in the heating power of the heating assembly and / or trigger the flow parameter adjusting member to increase the flow rate of the water inlet.

[0162] The second comparator compares the temperature from the water outlet of the second temperature measuring element with the boiling temperature, and if the temperature of the water outlet is above the boiling temperature for a long time, the second comparator will emit a signal to trigger a reduction in the heating power of the heating assembly and / or trigger the flow parameter adjusting member to increase the flow rate of the water inlet, so as to meet the sterilization demand and achieve energy-saving and emission reduction of the product; if the temperature of the water outlet is lower than the boiling temperature, the second comparator will not output a signal to maintain the heating power of the heating assembly and / or maintain the flow rate of the water inlet; of course, if the temperature of the water outlet is lower than the boiling temperature, the output signal of the second comparator may be designed to trigger an increase in the heating power of the heating assembly and / or trigger the flow parameter adjusting member to reduce the flow rate of the water inlet.

[0163] In one possible design, the preset temperature threshold is between 90°C and 100°C and / or the boiling temperature is between 90°C and 100°C.

[0164] In this design, the preset temperature threshold is set to 90-100°C, which can maintain the water temperature in the heating assembly at substantially 90-100°C, which has a good sterilization effect and improves food safety.

[0165] Setting the boiling temperature at 90℃~100℃ can meet the needs of use at various altitudes, allowing for more accurate control of the product in relation to the product's use environment, meeting sterilization demands, and better achieving energy conservation and emission reduction for the product.

[0166] In one possible design, the temperature measurement system includes a third temperature measurement element that collects the temperature of the liquid discharge nozzle and responds by issuing a corresponding signal based on the collected results, and a control assembly connected to the third temperature measurement element, and the control assembly controls liquid flow parameters in the first heat exchange flow path based on the signal from at least the third temperature measurement element.

[0167] In this design, the liquid discharge nozzle temperature is collected and parameters such as the liquid flow rate and flow velocity in the first heat exchange channel are adjusted accordingly. This feedback adjustment has a more timely response and can quickly adjust the water temperature of the liquid discharge nozzle to the target value, more accurately stabilizing the hot water temperature of the product. At the same time, this structure ensures that the hot water flow rate of the liquid discharge nozzle meets demand and makes the hot water flow rate more stable.

[0168] In one possible design, the liquid heating appliance further includes a command receiving element configured to obtain a target temperature command or a target level command, and a control assembly connected to the command receiving element, and the control assembly controls the flow rate in the first heat exchange flow path based on the temperature from the liquid discharge nozzle of at least the third temperature measuring element and the target temperature command or the target level command from the command receiving element.

[0169] In this design, the control assembly controls the flow rate in the first heat exchange passage based on the temperature of the liquid discharge nozzle and the target water temperature command or the target level command. For example, if the temperature of the liquid discharge nozzle is lower than the target water temperature command or the target level command, the flow rate in the first heat exchange passage is reduced, thereby correspondingly reducing the cooling rate in the second heat exchange passage, allowing the temperature of the liquid discharge nozzle to quickly rise to the target water temperature command or the target level command. If the temperature of the liquid discharge nozzle is higher than the target water temperature command or the target level command, the flow rate in the first heat exchange passage is increased, thereby correspondingly increasing the cooling rate in the second heat exchange passage, allowing the temperature of the liquid discharge nozzle to quickly cool to the target water temperature command or the target level command. This feedback adjustment has higher response timeliness and accuracy, allowing the water temperature of the liquid discharge nozzle to be quickly adjusted to the target value and more accurately stabilizing the hot water temperature of the product.

[0170] In one possible design, the temperature measurement system includes a fourth temperature measurement element, which collects the feedwater temperature of the first heat exchange flow path and responds by issuing a corresponding signal based on the collected results, and a control assembly connected to the fourth temperature measurement element, which controls liquid flow parameters in the first heat exchange flow path based on the signal from at least the fourth temperature measurement element.

[0171] In this design, the water temperature in the first heat exchange passage may affect the hot water temperature of the liquid discharge nozzle. By collecting the water temperature of the first heat exchange passage and invoking a different first heat exchange passage water flow control program accordingly, the stability of the hot water temperature of the liquid discharge nozzle can be better ensured.

[0172] In one possible design, the liquid heating appliance further includes a fifth temperature measuring element connected to the control assembly, the fifth temperature measuring element collecting the ambient temperature and feeding the collected ambient temperature back to the control assembly.

[0173] In this design, a fifth temperature measuring element is provided to collect the ambient temperature and feed it back to the control assembly. This allows the control assembly to predict the heat transferred to the air based on the ambient temperature, and more accurately determine and calibrate the measurement accuracy of each temperature measuring point in the water channel system according to the ambient heat dissipation rate. This allows for more accurate temperature control adjustment of the water channel system and more accurate prediction of the hot water temperature at the liquid discharge nozzle, so that the actual hot water temperature can better meet the user's desired target temperature.

[0174] In one possible design, the flow parameter adjustment member includes a first pump connected to the first heat exchange flow path and electrically connected to a control assembly, and / or a second pump connected to the water inlet and electrically connected to a control assembly, the control assembly adjusting operating parameters of the first pump to control liquid flow parameters in the first heat exchange flow path and adjusting operating parameters of the second pump to control liquid flow parameters at the water inlet.

[0175] In this design, the provision of the first pump and / or the second pump provides drive for the liquid in the waterway system and meets the driving force demand of the waterway system. The control assembly controls the first pump and / or the second pump to better control the liquid flow parameters such as the water supply rate and flow velocity of the first heat exchange passage and / or the water supply rate and flow velocity of the heating assembly, thereby more accurately controlling the heat exchange efficiency in the heat exchange box and thereby more accurately controlling the hot water temperature of the liquid discharge nozzle. The water supply rate and flow velocity of the heating assembly can be better matched to the heating efficiency of the heating assembly, thereby better ensuring the sterilization effect and more accurately adjusting and controlling the hot water temperature of the liquid discharge nozzle, while realizing energy conservation and reduced product emissions.

[0176] In one possible design, the waterway system further comprises a water distribution box, and a first pump of the flow parameter adjusting member is connected to the water distribution box and suitable for driving the liquid to flow between the first heat exchange flow path and the water distribution box, and / or a second pump of the flow parameter adjusting member is connected to the water distribution box and suitable for driving the liquid to flow from the water distribution box to the water inlet.

[0177] In this design, the installation of a water distribution box to relay and allocate the water flow can achieve better allocation of the water flow within the waterway system, more rational and sequential adjustment and control of cold and hot water, better realize the allocation of water temperature and flow rate adjustment control at each position within the waterway system, ensure more accurate hot water temperature at the liquid discharge nozzle, improve heat recovery of the product, and make the product more energy-efficient.

[0178] A technical solution of a sixth aspect of the present application provides a method for controlling a liquid heating appliance used in the liquid heating appliance of any one of the above technical solutions, the method for controlling a liquid heating appliance comprising the steps of measuring a temperature of a waterway system, and controlling the heating power of a heating assembly and / or liquid flow parameters in the waterway system based on the collected temperature of the waterway system.

[0179] The control method for a liquid heating appliance according to the present application measures the temperature of a water channel system, and allows the control assembly to timely adjust the heating power of the heating assembly and / or the liquid flow parameters in the water channel system according to the temperature conditions of the water channel system, thereby forming a water channel system temperature regulation control, which can improve the stability and accuracy of the hot water temperature of the product, ensure that the actual hot water temperature of the product better meets the hot water temperature demand, improve the product usage experience, and have the advantages of fast response speed and high control accuracy, which is beneficial to the improvement of instant-heat liquid heating products.

[0180] In one possible design, measuring the temperature of the waterway system specifically includes collecting the temperature of a water inlet of a heating assembly in the waterway system, and controlling the heating power of the heating assembly and / or a liquid flow parameter within the waterway system based on the collected waterway system temperature specifically includes generating a power parameter and a first flow parameter based on at least the water inlet temperature, controlling the heating power of the heating assembly to the power parameter, and controlling the flow rate of the water inlet to the first flow parameter.

[0181] In this design, the water inlet temperature of the heating assembly is collected, and based on the water temperature of the heating assembly in accordance with the law of conservation of energy, the heating power of the heating assembly and the liquid flow parameters in the water channel system can be substantially estimated based on the water temperature of the heating assembly in relation to the hot water temperature demand and / or sterilization temperature demand of the liquid discharge nozzle. This allows the heating load of the heating assembly to be substantially matched with the energy output, thereby ensuring high operating efficiency of the heating assembly and better sterilization effect of the heating assembly on the liquid. For example, this can better ensure that the water in the heating assembly is heated to boiling, improving food safety, and the liquid discharge nozzle temperature can be quickly reached before and after the hot water temperature demand of the liquid discharge nozzle, thereby improving the hot water supply time and temperature stability of the liquid discharge nozzle, and improving the heat exchange efficiency of the heat exchange box of the product, thereby achieving the accuracy and stability of the hot water temperature of the liquid discharge nozzle.

[0182] In one possible design, measuring the temperature of the water channel system specifically includes collecting the temperature of a water outlet of a heating assembly in the water channel system, and controlling the heating power of the heating assembly and / or liquid flow parameters within the water channel system based on the collected water channel system temperature specifically includes adjusting the heating power of the heating assembly and / or the water inlet flow rate if the water outlet temperature is outside a target hot water temperature range so that the water outlet temperature meets the target hot water temperature range.

[0183] In this design, collecting the water outlet temperature and feedback adjusting the heating power of the heating assembly and / or the liquid flow parameters in the water channel system based on the water outlet temperature allows the water outlet temperature to be more accurately adjusted within the target hot water temperature range, thus making the hot water temperature at the liquid discharge nozzle more accurate, better ensuring the sterilization effect of the product, and more advantageously ensuring high efficiency and accuracy of heat exchange in the heat exchange box.

[0184] For example, if the temperature of the water outlet is lower than the target hot water temperature range, the heating power of the heating assembly may be appropriately increased and / or the flow rate (or speed) of the water inlet of the heating assembly may be decreased so that the temperature of the water outlet can be increased to some extent to fall within the target hot water temperature range. Alternatively, for example, if the temperature of the water outlet is higher than the target hot water temperature range, the heating power of the heating assembly may be appropriately decreased and / or the flow rate (or speed) of the water inlet of the heating assembly may be increased so that the temperature of the water outlet can be decreased to some extent to fall within the target hot water temperature range.

[0185] In one possible design, measuring the temperature of the water channel system specifically includes collecting the temperature of a water outlet of a heating assembly in the water channel system, and controlling the heating power of the heating assembly and / or liquid flow parameters within the water channel system based on the collected water channel system temperature specifically includes increasing the heating power of the heating assembly and / or decreasing the flow rate of the water inlet if the temperature of the water outlet does not exceed a predetermined temperature threshold.

[0186] In this design, if the temperature of the water outlet is below a preset temperature threshold, the heating power of the heating assembly is increased and / or the flow rate or volume of the water inlet is controlled to be reduced, so that the temperature of the liquid discharged from the heating assembly increases accordingly, thereby better meeting the sterilization demand and improving food safety. If the temperature of the water outlet is higher than the preset temperature threshold, the heating power of the heating assembly and / or the flow rate of the water inlet can be maintained as they are; of course, if the temperature of the water outlet is higher than the preset temperature threshold, the heating power of the heating assembly can be reduced and / or the flow parameter adjusting member can be triggered to increase the flow rate of the water inlet.

[0187] In one possible design, measuring the temperature of the waterway system specifically includes collecting the temperature of a water outlet of a heating assembly in the waterway system, and controlling the heating power of the heating assembly and / or liquid flow parameters within the waterway system based on the collected waterway system temperature specifically includes reducing the heating power of the heating assembly and / or increasing the flow rate of the water inlet if the temperature of the water outlet within a first predetermined length of time is at least the boiling temperature.

[0188] In this design, if the temperature of the water outlet collected within the first preset time range is at least the boiling temperature, the heating power of the heating assembly can be controlled to decrease and / or the flow rate of the water inlet can be controlled to increase, so as to meet the sterilization demand and achieve energy-saving and emission reduction. If the temperature of the water outlet is lower than the boiling temperature, the heating power of the heating assembly can be maintained and / or the flow rate of the water inlet can be maintained. Of course, if the temperature of the water outlet is lower than the boiling temperature, the heating power of the heating assembly can be increased and / or the flow rate of the water inlet can be decreased.

[0189] In one possible design, the preset temperature threshold is between 90°C and 100°C and / or the boiling temperature is between 90°C and 100°C.

[0190] In this design, the preset temperature threshold is set to 90-100°C, which can maintain the water temperature in the heating assembly at substantially 90-100°C, which has a good sterilization effect and improves food safety.

[0191] Setting the boiling temperature at 90℃~100℃ can meet the needs of use at various altitudes, allowing for more accurate control of the product in relation to the product's use environment, meeting sterilization demands, and better achieving energy conservation and emission reduction for the product.

[0192] In one possible design, measuring the temperature of the waterway system specifically includes collecting the temperature of a water inlet of a heating assembly in the waterway system, and controlling the heating power of the heating assembly and / or liquid flow parameters within the waterway system based on the collected waterway system temperature specifically includes reducing the heating power of the heating assembly and / or increasing the water inlet flow rate if the water inlet temperature within a second predetermined length of time trends upward.

[0193] In this design, if the collected water inlet temperature shows an upward trend or continues to rise within the time range of the second preset length of time, the heating power of the heating assembly is reduced and / or the water inlet flow rate is increased, thereby more timely controlling the stability of the hot water temperature of the heating assembly and preventing the problem of large fluctuations in the hot water temperature of the heating assembly. This makes the liquid discharge nozzle temperature correspondingly more stable and accurate, preventing the problem of product temperature control adjustment distortion and more favorable to accurate adjustment of the liquid discharge nozzle temperature. This also reduces the heat exchange load and temperature fluctuation of the heat exchange box, which is more favorable to maintaining high-efficiency and stable operation of the heat exchange box.

[0194] In one possible design, measuring the temperature of the water channel system specifically includes collecting the temperature of a liquid discharge nozzle in the water channel system, and controlling the heating power of the heating assembly and / or liquid flow parameters in the water channel system based on the collected water channel system temperature specifically includes increasing the flow rate in a first heat exchange flow path of the water channel system if the temperature of the liquid discharge nozzle is higher than a target hot water temperature corresponding to a target temperature command or a target level command, and decreasing the flow rate in the first heat exchange flow path if the temperature of the liquid discharge nozzle is lower than a target hot water temperature corresponding to a target temperature command or a target level command.

[0195] In this design, the liquid discharge nozzle temperature is collected and parameters such as the liquid flow rate and flow velocity in the first heat exchange channel are adjusted accordingly. This feedback adjustment has a more timely response and can quickly adjust the water temperature of the liquid discharge nozzle to the target value, more accurately stabilizing the hot water temperature of the product. At the same time, this structure ensures that the hot water flow rate of the liquid discharge nozzle meets demand and makes the hot water flow rate more stable.

[0196] In one possible design, the control method for a liquid heating appliance further includes the steps of collecting a water supply temperature of a first heat exchange flow path of the water channel system, generating a second flow parameter based on a target hot water temperature corresponding to a target temperature command or a target level command and the water supply temperature of the first heat exchange flow path, and controlling the flow rate of the first heat exchange flow path to the second flow parameter.

[0197] In this design, by collecting the water supply temperature of the first heat exchange passage and adjusting the flow rate of the first heat exchange passage accordingly, the water flow rate load of the first heat exchange passage can be more accurately estimated through the water supply temperature of the first heat exchange passage. In this way, by controlling the water flow rate of the first heat exchange passage based on the water supply temperature of the first heat exchange passage, the consistency between the heat input and output of the heat exchange box can be improved. In this way, a relatively high accuracy of the water supply temperature can be obtained at the beginning of hot water supply of the product, the effect of instant hot water supply is better, and the temperature fluctuations of the liquid discharge nozzle are also effectively controlled, and the water temperature of the liquid discharge nozzle is more stable.

[0198] In one possible design, the method for controlling a liquid heating appliance further includes collecting an ambient temperature, generating a first correction parameter and / or a second correction parameter based on the ambient temperature, and controlling the heating power of the heating assembly to increase or decrease the first correction parameter, and / or controlling the liquid flow parameter in the waterway system to increase or decrease the second correction parameter.

[0199] In this design, the ambient temperature is collected and the heating power and / or liquid flow parameters of the water channel system are corrected based on the ambient temperature, thereby reducing the hot water temperature error caused by the ambient temperature and improving the accuracy of the hot water temperature.

[0207] In order to better understand the above-mentioned objects, features and advantages of the present application, the present application will now be described in more detail in conjunction with the drawings and specific embodiments. It should be noted that, unless there is a contradiction, the embodiments and features of the embodiments of the present application can be combined with each other.

[0208] Although numerous details are set forth in the following description for a thorough understanding of the present application, the present application may be embodied in forms different from those described herein, and the scope of protection of the present application is not limited to the specific examples disclosed below.

[0209] Next, with reference to Figures 1 to 90, a liquid treatment device, a heat exchange device, a heat exchange box, a liquid heating appliance, a method for controlling a liquid heating appliance, a control device for a liquid heating appliance, and a computer-readable storage medium according to several embodiments of the present application will be described.

[0210] As shown in Figures 1 to 7, a liquid treatment device according to some embodiments of the first aspect of the present application includes a liquid supply passage, a heating assembly 2, a liquid discharge passage 32, and a heat exchanger 4. Specifically, the heat exchanger 4 is in communication with the liquid supply passage and the liquid discharge passage 32, and can transport the liquid that has entered the heat exchanger 4 to the liquid discharge passage 32 after heat exchange. The heating assembly 2 is provided corresponding to the liquid supply passage and / or the heat exchanger 4, or a heating passage connected between the liquid supply passage and the heat exchanger 4 is provided within the heating assembly 2.

[0211] The liquid treatment device according to the embodiment of the present application includes a liquid supply channel, a heating assembly 2, a liquid discharge channel 32, and a heat exchanger 4. The liquid supply channel may be directly connected to an external water source, such as a water pipe in a user's home, so that water can be supplied via the water pipe in the user's home. The liquid supply channel may be a channel within an external member, or may be a built-in channel within the heat exchanger 4. The liquid supply channel may also be connected to an internal or external liquid supply tank 5 so that water is supplied via the liquid supply tank 5. The heating assembly 2 is for heating. Specifically, the heating assembly 2 may be provided inside or outside the liquid supply channel corresponding to the liquid supply channel to heat the water in the liquid supply channel, or the heating assembly 2 may be provided inside or outside the heat exchanger 4 corresponding to the heat exchanger 4 to heat the water in the heat exchanger 4. Of course, the heating assembly 2 may be provided as a structure including a heating flow path, and the heating assembly 2 may be connected between the liquid supply flow path and the heat exchanger 4 so that the heat exchanger 4 can communicate with the liquid supply flow path via the heating flow path. In this case, water entering from the liquid supply flow path first enters the heating flow path, is heated in the heating flow path, enters the heat exchanger 4, and is heat exchanged through the heat exchanger 4 before flowing out from the liquid discharge flow path 32. In such an embodiment, the liquid supply flow path may be a flow path within a member provided independently from the heating assembly 2 and the heat exchanger 4, or, of course, may be an internal flow path that communicates with the heating flow path within the heating assembly 2. On the one hand, the heat exchanger 4 is provided corresponding to the liquid discharge flow path 32 and can cool the liquid in the liquid discharge flow path 32 so that the liquid in the liquid discharge flow path 32 can be discharged after being cooled to an appropriate temperature, and on the other hand, the heat exchanger 4 can be provided between the heating assembly 2 and the liquid discharge flow path 32 and the heat exchanger 4 can be connected to the heating flow path and the liquid discharge flow path 32, and in this way, the hot water heated by the heating device can be cooled through the heat exchanger 4 before being transported into the liquid discharge flow path 32 and discharged from the liquid discharge flow path 32. The liquid discharge flow path 32 here may be a flow path independently provided in an external member of the heat exchanger 4, or, of course, it may be a single built-in flow path inside the heat exchanger 4.With this structure, when it is necessary to provide hot water below boiling temperature (e.g., water at 25°C-70°C), the water can be heated to a relatively high temperature by the heating assembly 2, and then heated to the boiling temperature. After the water is heated to a relatively high temperature, the relatively high temperature water is transported to the liquid discharge flow path 32 and cooled within the liquid discharge flow path 32 using the heat exchanger 4; alternatively, the water is heated by the heating assembly 2, and then the heated water is transported directly to the heat exchanger 4, cooled through the heat exchanger 4, transported to the liquid discharge flow path 32, and discharged through the liquid discharge flow path 32 so that the user can drink it. With this structure, relatively high-temperature water can be cooled through the heat exchanger 4 to a relatively low temperature, such as a temperature specified by the user or a temperature that is easy for the user to drink directly, and the water cooled to a relatively low temperature can then be discharged through the water outlet of the liquid discharge flow path 32. In this manner, when providing relatively low-temperature water, high-temperature sterilization or disinfection can be achieved by first heating the water to a relatively high temperature through the heating assembly 2, thereby killing bacteria and microorganisms in the water through heating. As a result, when providing water at a specified temperature, bacteria and the like in the water can be removed in advance, thereby ensuring the cleanliness and hygiene of the relatively low-temperature hot water provided by the product.

[0212] In some embodiments, as shown in Figures 1 to 18, the liquid treatment device further includes a liquid supply assembly 1 and a liquid discharge assembly 3, wherein the liquid supply flow path is provided in the liquid supply assembly 1 and the liquid discharge flow path 32 is provided in the liquid discharge assembly 3.

[0213] In these embodiments, the liquid treatment device further includes a liquid supply assembly 1 and a liquid discharge assembly 3. The liquid supply assembly 1 is connected to a water source and is used to supply water to the heat exchange device 4 or the heating channel, and the liquid discharge assembly 3 is used to discharge water from the outlet of the heat exchange device 4. In such a liquid treatment device, the liquid supply assembly 1, the heat exchange device 4, and the liquid discharge assembly 3 are provided independently, thus making the overall product relatively simple and facilitating its processing. Of course, in another embodiment, the liquid supply assembly 1 and the liquid discharge assembly 3 do not need to be provided independently. In this case, the liquid supply channel, the liquid discharge channel 32, the heating assembly 2, and the heat exchange device 4 may be integrated into a single component that provides water supply, heating, heat exchange, and hot water supply. Of course, in yet another embodiment, the heat exchange device 4, the liquid discharge channel 32, and the liquid supply channel may be integrated, but the heating assembly 2 may be provided as a separate component. Of course, the heating assembly 2 and the liquid supply passage may be provided integrally, in which case the heat exchanger 4 and the liquid discharge passage 32 may be integrated or may be separate components.

[0214] In some embodiments, when a heating flow path is provided within the heating assembly 2 and the heating flow path is connected between the liquid supply flow path and the heat exchange device 4, the heating assembly 2 and the liquid supply assembly 1 are separate structures, and when the heating assembly 2 is provided corresponding to the liquid supply assembly 1, the heating assembly 2 is provided within the liquid supply flow path, and when the heating assembly 2 is provided corresponding to the heat exchange device 4, the heating assembly 2 is provided within the heat exchange device 4.

[0215] In these embodiments, the heating assembly 2 may be provided in a structure including a heating flow path, and the heating assembly 2 may be connected between the liquid supply flow path and the heat exchanger 4 so that the heat exchanger 4 can communicate with the liquid supply flow path through the heating flow path. In this case, water entering from the liquid supply flow path first enters the heating flow path, is heated in the heating flow path, enters the heat exchanger 4, and exchanges heat through the heat exchanger 4 before flowing out from the liquid discharge flow path 32. In this case, the heating assembly 2, the heat exchanger 4, and the liquid supply device may be separate structures, i.e., the heating assembly 2 may be a structure independent of the heat exchanger 4 and the liquid supply device. Of course, in another embodiment, the heating assembly 2, the heat exchanger 4, and the liquid supply device may be an integral structure, for example, an integrally assembled structure or an integrally molded structure. Furthermore, in yet another embodiment, the heating assembly 2 may be directly provided in the heat exchanger 4, in which case the liquid can be directly heated in the heat exchanger 4. Of course, the heating assembly 2 may also be directly provided in the liquid supply flow path, in which case the liquid can be directly heated in the liquid supply flow path. When the heating assembly 2 is provided in the heat exchange device 4 or the liquid supply passage, the heating assembly 2 and the heat exchange device 4 or the liquid supply passage may be an integral structure or separate structures.

[0216] A heat exchange passage may be provided within the heat exchange device 4 so that the liquid that has entered the heat exchange passage can be transported to the liquid discharge passage 32 after heat exchange. Of course, a non-heat exchange passage may also be provided within the heat exchange device 4, in which case the liquid that has entered the non-heat exchange passage can be transported directly to the liquid discharge passage 32 without being cooled. That is, although the heat exchange device 4 has a heat exchange function for cooling water, it is not meant to imply that the liquid that has entered the heat exchange device 4 must be transported to the liquid discharge passage 32 after undergoing heat exchange. In other words, the liquid that has passed through the heat exchange device 4 can directly flow out without undergoing heat exchange.

[0217] In some embodiments, as shown in Figures 8 and 9, the heat exchange device 4 includes a first heat exchange passage 40 and a second heat exchange passage 42, the second heat exchange passage 42 being in communication with the liquid supply passage and the liquid discharge passage 32, and the first heat exchange passage 40 being capable of exchanging heat with the second heat exchange passage 42 to cool the liquid in the second heat exchange passage 42.

[0218] In these embodiments, the heat exchange device 4 includes a first heat exchange passage 40 and a second heat exchange passage 42, and the second heat exchange passage 42 may be connected to the liquid supply passage and the liquid discharge passage 32. In this way, the liquid, such as water, heated by the heating assembly 2 can be cooled by heat exchange with the first heat exchange passage 40 in the second heat exchange passage 42 and then discharged through the liquid discharge assembly 3. The temperature of the high-temperature liquid heated by the heating assembly 2 when flowing through the second heat exchange passage 42 is higher than the temperature of the cooling liquid in the first heat exchange passage 40. In this way, the first heat exchange passage 40 can continuously absorb heat from the liquid, such as water, in the second heat exchange passage 42 to realize heat exchange between the first heat exchange passage 40 and the second heat exchange passage 42. As a result, the liquid, such as water, in the second heat exchange passage 42 can be cooled by heat exchange between the first heat exchange passage 40 and the second heat exchange passage 42. This structure utilizes the principle of heat exchange to cool the liquid, such as water, heated by the heating device. This cooling method is simple and easy to implement, thereby simplifying the product structure and reducing the cost of the product. Of course, other cooling methods may be used, such as air cooling using an electric fan, in which case the heat exchanger 4 may be an air-cooling device.

[0219] Furthermore, when a heating flow path is provided in the heating assembly 2, the second heat exchange flow path 42 is connected to the liquid supply flow path via the heating flow path, and when the heating assembly 2 is provided in the heat exchange flow path, the heating assembly 2 is provided in the second heat exchange flow path 42.

[0220] In these embodiments, when a heating flow path is provided in the heating assembly 2, the second heat exchange flow path 42 can be connected to the liquid supply flow path via the heating flow path, and in this way, a liquid such as water can pass through the liquid supply flow path and the heating flow path sequentially and enter the second heat exchange flow path 42; on the other hand, when the heating assembly 2 is provided in the heat exchange device 4, the heating assembly 2 can be provided in the second heat exchange flow path 42 so as to directly heat the water in the second heat exchange flow path 42, and in this case, the first half of the second heat exchange flow path 42 can be used for heating, and the second half can be used for heat exchange cooling of a liquid such as water.

[0221] In some embodiments, the inlet of the first heat exchange passage 40 is connected to the liquid supply passage, and when the second heat exchange passage 42 is connected to the liquid supply passage via the heating passage, the outlet of the first heat exchange passage 40 is connected to the inlet of the heating passage or to the liquid supply passage.

[0222] In these embodiments, the first heat exchange passage 40 can, on the one hand, connect the liquid supply passage and the inlet of the heating passage, while the outlet of the heating passage is connected to the second heat exchange passage 42; therefore, in the present application, the liquid supply passage-first heat exchange passage 40-heating passage and the second heat exchange passage 42 are connected end to end in sequence; in this way, a liquid such as water entering from the liquid supply passage first passes through the first heat exchange passage 40 of the heat exchange device 4, then enters the heating passage from the first heat exchange passage 40, and then enters the second heat exchange passage 42 from the heating passage, and after heat exchange with the first heat exchange passage 40 in the second heat exchange passage 42, is discharged from the outlet of the liquid discharge passage 32. This configuration allows the low-temperature liquid (i.e., unheated liquid) entering the liquid supply channel to be used to cool the liquid entering the second heat exchange channel 42 after heating. This eliminates the need for a separate cooling liquid or a separate cooling circulation circuit. Simply by rationally configuring the liquid channel structure within the product, cooling costs can be reduced. After heat exchange between the first heat exchange channel 40 and the second heat exchange channel 42, the liquid in the first heat exchange channel 40 absorbs heat from the liquid, such as water, in the second heat exchange channel 42, causing it to rise in temperature. The heated cooling liquid can then enter the heating channel directly for heating, thereby reducing the heat required to boil the liquid in the heating channel. This configuration allows water before heating to be used to cool the liquid after heating, and the cooling liquid that has absorbed the heat can be directly transported into the heating channel to heat the water to the desired temperature. This allows the excess heat in the heated water to be fully utilized, thereby improving the heat utilization rate of the product.

[0223] In another embodiment, the inlet of the first heat exchange passage 40 may be connected to the liquid supply passage, and then the outlet of the first heat exchange passage 40 may be connected directly to the liquid supply passage rather than to the inlet of the heating passage.In this way, the liquid that enters the first heat exchange passage 40 from the liquid supply passage is heat exchanged with the second heat exchange passage 42 so as to heat the liquid in the liquid supply passage, and then returned to the liquid supply passage via the first heat exchange passage 40, thereby increasing the temperature of the liquid that has entered the heating passage and realizing the recovery and utilization of heat in the first heat exchange passage 40. In one possible embodiment, a reservoir tank 44 may be connected to the liquid supply flow path so that the liquid in the liquid supply flow path can first enter the reservoir tank 44, and the inlet and outlet of the first heat exchange flow path 40 may be connected to the reservoir tank 44, and the inlet of the heating flow path may also be connected to the reservoir tank 44.In this way, on the one hand, the reservoir tank 44 can form a cooling circulation circuit together with the first heat exchange flow path 40 to realize cooling of the second heat exchange flow path 42, and on the other hand, the reservoir tank 44 can heat the liquid entering the heating flow path using hot water that has absorbed heat in the first heat exchange flow path 40 to realize heat reuse.

[0224] In some embodiments, as shown in Figures 6 and 7, the heat exchange device 4 further includes a reservoir tank 44 connected to the inlet of the first heat exchange flow path 40 and the outlet of the first heat exchange flow path 40 to form a cooling circulation circuit.

[0225] In these embodiments, a liquid storage tank 44 may be additionally provided to form a circuit with the first heat exchange flow path 40 via the liquid storage tank 44, thereby constantly providing cooling power to cool the liquid, such as water, in the liquid discharge flow path 32. This structure allows the cooling circuit to be independent of the liquid flow path consisting of the liquid supply assembly 1, the heating assembly 2, and the liquid discharge assembly 3. Thus, the cooling circuit and the liquid flow path can be operated independently, allowing the cooling circuit to be turned on or off independently. Whether to turn on the cooling circuit can be determined according to actual demand during operation of the liquid treatment device. When the cooling circuit is not turned on, heated water can be directly discharged at a corresponding temperature, e.g., boiling water. When the cooling circuit is turned on, water can be first heated to a relatively high temperature, e.g., boiling, and then cooled to a relatively low temperature before being discharged. This structure allows the product to directly heat water and then discharge it, or to first heat and cool water before discharging it, thereby expanding product functionality and realizing product diversification, thereby enabling the product to better meet various user needs.

[0226] In some embodiments, when a heating flow path is provided in the heating assembly 2, as shown in Figures 6 and 7, the reservoir tank 44 is in communication with the liquid supply flow path, and the heating flow path is directly connected to the liquid supply flow path, or the inlet of the heating flow path is connected to the reservoir tank 44 so that it is connected to the liquid supply flow path via the reservoir tank 44.

[0227] In these embodiments, a heating flow path is provided in the heating assembly 2, and the heating flow path is connected between the liquid supply flow path and the heat exchange device 4. When the heat exchange device 4 is in communication with the liquid supply flow path through the heating flow path, the liquid storage tank 44 can be connected between the inlet of the heating flow path and the liquid supply flow path. In this way, on the one hand, cooling liquid can be added to the liquid storage tank 44 through the liquid supply assembly 1, and on the other hand, the heat after heat exchange between the first heat exchange flow path 40 and the second heat exchange flow path 42 can be returned to the liquid storage tank 44 through the first heat exchange flow path 40 and the liquid in the liquid storage tank 44 can be heated. Considering that the heating flow path is also connected to the liquid storage tank 44, the heat after cooling heat exchange in the liquid storage tank 44 can be used to preheat liquid such as water that enters the heating flow path, thereby making full use of the heat generated by the heat exchange. In another embodiment, the heating flow path and the liquid storage tank 44 may be directly connected to the liquid supply flow path at the same time so that water can be supplied to the liquid storage tank 44 and the heating flow path simultaneously via the liquid supply flow path. In this case, cooling can be achieved with the cryogenic liquid that has entered the liquid supply flow path, but it is not possible to reuse the heat generated by the heat exchange in the first heat exchange flow path 40. However, in either embodiment, the cooling circulation flow path can be made independent of the liquid flow path, and therefore the cooling circulation flow path can be turned on or off independently without being affected by the liquid flow path.

[0228] 6 and 7, the reservoir tank 44 is in communication with the liquid supply passage, and the inlet of the heating passage is connected to the reservoir tank 44 so as to be connected to the liquid supply passage via the reservoir tank 44. A first pumping device is provided between the reservoir tank 44 and the liquid supply passage, and / or a second pumping device is provided between the inlet of the heating passage and the reservoir tank 44, and / or a third pumping device is provided between the first heat exchange passage 40 and the reservoir tank 44.

[0229] In these embodiments, the liquid storage tank 44 can be connected between the inlet of the heating flow path and the liquid supply flow path; thus, on the one hand, cooling liquid can be added to the liquid storage tank 44 through the liquid supply flow path of the liquid supply assembly 1; and on the other hand, the heat after heat exchange between the first heat exchange flow path 40 and the second heat exchange flow path 42 can be returned to the liquid storage tank 44 through the first heat exchange flow path 40 and heat the liquid in the liquid storage tank 44. Considering that the heating flow path is also connected to the liquid storage tank 44, this allows the heat after cooling heat exchange in the liquid storage tank 44 to be used to preheat liquid such as water entering the heating flow path, thereby making full use of the heat from the heat exchange. In this embodiment, a first pumping device may be provided between the storage tank 44 and the liquid supply passage so that the liquid in the liquid supply passage is pumped into the storage tank 44 by the first pumping device, a second pumping device may be provided between the inlet of the heating passage and the storage tank 44 so that the liquid in the storage tank 44 is pumped into the heating passage by the second pumping device, and a third pumping device may be provided between the first heat exchange passage 40 and the storage tank 44 so that the liquid in the storage tank 44 is pumped into the first heat exchange passage 40 by the third pumping device. This installation, on the one hand, can control the flow rate in the first heat exchange passage 40 via the third pumping device, and thereby control the cooling effect of the heat exchange device 4. Note that the third pumping device may be turned off to turn the first heat exchange passage 40 on or off, thereby controlling the on or off of the cooling function via the third pumping device. By providing three pumping devices, the liquid flow pressure can be increased and the flow rate can be increased, and at the same time, the flow rate can be controlled by adjusting the flow rate through each pumping device.

[0230] In some embodiments, the liquid treatment device further includes a temperature collection element disposed within the reservoir tank 44 for collecting the temperature of the liquid within the reservoir tank 44 .

[0231] In these embodiments, the temperature collection element is used to collect the temperature of the liquid in the reservoir tank 44 so that the flow rate of the cooling liquid in the first heat exchange flow path 40 can be controlled based on the temperature of the liquid in the reservoir tank 44 and further the cooling intensity can be controlled.

[0232] In some embodiments, when a heating flow path is provided in the heating assembly 2 and the second heat exchange flow path 42 communicates with the liquid supply flow path via the heating flow path, the liquid treatment device further includes a three-way valve, an inlet of which is connected to the outlet of the heating flow path and a first outlet of which is connected to the second heat exchange flow path 42. The liquid discharge assembly 3 further includes a branch flow path, one end of which is connected to the second outlet of the three-way valve and the other end of which is connected to the liquid discharge flow path 32.

[0233] In these embodiments, a heating flow path is provided in the heating assembly 2, and the heating flow path is connected between the liquid supply flow path and the heat exchange device 4, so that when the heat exchange device 4 is connected to the liquid supply flow path through the heating flow path, the outlet of the heating flow path can be connected to the inlet of the three-way valve, and the first outlet of the three-way valve can be connected to the inlet of the first heat exchange flow path 40, and the second outlet of the three-way valve can be connected to the liquid discharge flow path 32 via a branch flow path.In this way, water heated by the heating flow path enters the heat exchange flow path through the first outlet and performs heat exchange cooling before being discharged from the liquid discharge flow path 32, or is directly discharged from the liquid discharge flow path 32 via the second outlet and the branch flow path without passing through the heat exchange device 4. In this way, on the one hand, water heated by the heating flow path can be directly discharged from the liquid discharge flow path 32 via the branch flow path. On the other hand, the inlet and second outlet of the three-way valve can be blocked and the inlet of the three-way valve can be connected to the first outlet. In this way, water heated by the heating flow path can directly enter the heat exchanger 4, exchange heat with the first heat exchange flow path 40, and then be discharged. By providing a three-way valve, water heated by the heating flow path can be directly discharged without cooling to provide relatively high-temperature water, such as hot water. At the same time, water heated by the heating flow path can be cooled and then discharged to provide low-temperature liquid at the user's desired temperature. The installation of a three-way valve enables switching between the hot water and hot water functions, thereby making switching between the hot water and hot water stages more convenient.

[0234] The branch flow path here may be incorporated into the heat exchange device 4 so as to become part of the heat exchange device 4, in which case heat exchange cooling of a liquid such as water can be performed via the heat exchange device 4 having three flow paths.

[0235] In one possible embodiment, the liquid discharging assembly 3 further includes a liquid discharging nozzle 34 connected to the outlet of the liquid discharging channel 32. By providing the liquid discharging nozzle 34, the hot water dispensing position, hot water dispensing height, etc. of the product can be adjusted, thus making it more convenient for the user to receive liquids such as water.

[0236] In some embodiments, as shown in Figures 15 and 16, the first heat exchange passage 40 is a tortuous passage with a reciprocating bend and / or the second heat exchange passage 42 is a tortuous passage with a reciprocating bend.

[0237] In these embodiments, the first heat exchange passage 40 and / or the second heat exchange passage 42 may be configured to be a curved passage with a reciprocating bend, thereby extending the length of the first heat exchange passage 40 and / or the second heat exchange passage 42 and improving the heat exchange effect of the heat exchange device 4. In one possible embodiment, the curved passage is a serpentine passage, or the curved passage is made up of a plurality of S-shaped passages connected to each other end to end, or the curved passage is made up of a plurality of N-shaped passages connected to each other end to end.

[0238] In some embodiments, the inlet of the first heat exchange flow path 40 and the inlet of the second heat exchange flow path 42 are located on the same side of the heat exchange device 4, and the outlet of the first heat exchange flow path 40 and the outlet of the second heat exchange flow path 42 are located on the same side of the heat exchange device 4.

[0239] In these embodiments, since the temperature at the inlet of the first heat exchange flow path 40 is lower than the temperature at the outlet of the first heat exchange flow path 40, i.e., the temperature gradually increases from the inlet to the outlet of the first heat exchange flow path 40, the heat exchange efficiency gradually decreases and the temperature at the inlet of the second heat exchange flow path 42 becomes higher than the temperature at the outlet of the second heat exchange flow path 42. Therefore, the inlet of the first heat exchange channel 40 and the inlet of the second heat exchange channel 42 may be located on the same side of the heat exchanger 4, for example, both on the right side. At the same time, the outlet of the first heat exchange channel 40 and the outlet of the second heat exchange channel 42 may be located on the same side of the heat exchanger 4, for example, both on the left side. In this way, the flow directions of the liquid in the first heat exchange channel 40 and the second heat exchange channel 42 are aligned, i.e., the inlet direction of the cooling liquid is aligned with the inlet direction of the hot water in the second heat exchange channel 42, and the outlet direction of the cooling liquid is also aligned with the outlet direction of the hot water in the second heat exchange channel 42. With this arrangement, the coldest cooling liquid can exchange heat with the hottest hot water, thereby increasing the heat exchange rate and cooling speed and thereby improving the heat exchange cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage 40 and the second heat exchange passage 42 do not coincide, the liquid at the inlet of the second heat exchange passage 42 will exchange heat with the liquid at the outlet of the first heat exchange passage 40, and the liquid at the outlet of the second heat exchange passage 42 will exchange heat with the liquid at the inlet of the first heat exchange passage 40.With such an installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0240] 8 to 14 , in some embodiments, the heat exchange device 4 includes an outer casing 46 and a heat conductive partition wall 48 provided in the outer casing 46, and the first heat exchange passage 40 and the second heat exchange passage 42 are provided on either side of the heat conductive partition wall 48. The outer casing 46 is provided with a first inlet corresponding to the first heat exchange passage 40 and communicating with the first heat exchange passage 40, and a first outlet communicating with the first heat exchange passage 40. The outer casing 46 is provided with a second inlet corresponding to the second heat exchange passage 42 and communicating with the second heat exchange passage 42, and a second outlet communicating with the second heat exchange passage 42.

[0241] In these embodiments, the heat exchange device 4 includes an outer casing 46 and a thermally conductive partition wall 48. The outer casing 46 is used to form an enclosed space, and the thermally conductive partition wall 48 is used to divide the interior space of the outer casing 46 into two parts, thereby forming two independent flow paths within the outer casing 46. In a specific example, one of the two flow paths divided by the thermally conductive partition wall 48 can be used as the first heat exchange flow path 40, and the other can be used as the second heat exchange flow path 42. The first heat exchange flow path 40 and the second heat exchange flow path 42 in the heat exchange device 4 having such a structure are divided by the thermally conductive partition wall 48, thereby making heat transfer between the two flow paths more convenient and efficient. Furthermore, the structure of the heat exchange device 4 having such a structure is relatively simple and easy to process, thereby reducing production costs. In addition, an inlet / outlet may be provided in the outer casing 46 corresponding to the first heat exchange flow path 40, and an inlet / outlet may be provided in the outer casing 46 corresponding to the second heat exchange flow path 42, so that liquid outside the heat exchange device 4 can enter the first heat exchange flow path 40 and the second heat exchange flow path 42 through the corresponding inlets / outlets.

[0242] In some embodiments, as shown in Figures 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 and 18 , the outer casing 46 includes a first casing 462 shown in Figures 15 to 18 , a second casing 464 attached to the first casing 462, a thermally conductive partition wall 48 attached to the connection between the first casing 462 and the second casing 464, a first sealing ring 466 provided between the thermally conductive partition wall 48 and the first casing 462 to seal between the thermally conductive partition wall 48 and the first casing 462, and a second sealing ring 468 provided between the thermally conductive partition wall 48 and the second casing 464 to seal between the thermally conductive partition wall 48 and the second casing 464.

[0243] In these embodiments, a sealed space may be formed between the first housing 462 and the second housing 464, and two flow paths may be partitioned therein by the thermally conductive partition 48. This configuration allows the outer housing 46 of the heat exchanger 4 to be divided into multiple members, thereby making each member relatively simple and reducing the processing difficulty and cost. When installed, the thermally conductive partition 48 may be attached to the connecting portion between the first housing 462 and the second housing 464, i.e., one portion of the thermally conductive partition 48 is attached within the first housing 462, and the other portion of the thermally conductive partition 48 is attached within the second housing 464. In one possible embodiment, a first sealing ring 466 may be provided between the first housing 462 and the thermally conductive partition wall 48 to achieve sealing between the first housing 462 and the thermally conductive partition wall 48 via the first sealing ring 466, and at the same time, a second sealing ring 468 may be provided between the second housing 464 and the thermally conductive partition wall 48 to achieve sealing between the second housing 464 and the thermally conductive partition wall 48 via the second sealing ring 468. The provision of the first sealing ring 466 and the second sealing ring 468 can prevent water leakage at the connection between the first housing 462 and the second housing 464.

[0244] In another possible embodiment as shown in Figures 10 to 18, the outer casing 46 includes a first casing 462 as shown in Figures 15 to 18, a second casing 464 attached to the first casing 462, and a third sealing ring (not shown) attached to the connection between the first casing 462 and the second casing 464 for sealingly connecting the first casing 462 and the second casing 464, and the thermally conductive partition 48 is attached within the first casing 462 or the second casing 464 (not shown in this embodiment).

[0245] In these embodiments, a sealed space may be formed between the first housing 462 and the second housing 464, and two flow paths may be partitioned therein via the thermally conductive partition 48. This arrangement allows the outer housing 46 of the heat exchanger 4 to be divided into multiple members, thereby making each member relatively simple and reducing the difficulty and cost of processing. The installation of a third sealing ring can seal the first housing 462 and the second housing 464, thereby preventing water leakage at the connection between the first housing 462 and the second housing 464.

[0246] In some embodiments, the first inlet and the second inlet are located on the same side of the outer housing 46, and the first outlet and the second outlet are located on the same side of the outer housing 46.

[0247] In these embodiments, the first inlet and the second inlet are located on the same side of the outer casing 46, and the first outlet and the second outlet are located on the same side of the outer casing 46, which aligns the liquid flow directions in the first heat exchange channel 40 and the second heat exchange channel 42, i.e., the inlet direction of the cooling liquid is aligned with the inlet direction of the hot water in the second heat exchange channel 42, and the outlet direction of the cooling liquid is aligned with the outlet direction of the hot water in the second heat exchange channel 42. With this arrangement, the coldest cooling liquid can exchange heat with the hottest hot water, which can speed up the cooling speed and therefore improve the cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage 40 and the second heat exchange passage 42 do not coincide, the liquid at the inlet of the second heat exchange passage 42 will exchange heat with the liquid at the outlet of the first heat exchange passage 40, and the liquid at the outlet of the second heat exchange passage 42 will exchange heat with the liquid at the inlet of the first heat exchange passage 40.With such an installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0248] In some embodiments, the outer surfaces of first housing 462 and / or second housing 464 are provided with heat dissipation fins.

[0249] In these embodiments, heat can be dissipated through the heat dissipation fins, thereby improving the heat dissipation efficiency of the heat exchange device 4. The heat dissipation fins may be provided on the first housing 462 or on the second housing 464, or, of course, the heat dissipation fins may be provided on both the first housing 462 and the second housing 464 at the same time.

[0250] In some embodiments, as shown in Figures 15 and 16, a plurality of first barrier ribs 4622 are provided on the inner surface of the first housing 462, and the plurality of first barrier ribs 4622 define a flow path between the first housing 462 and the thermally conductive partition 48 into a tortuous flow path with a reciprocating bend.

[0251] In these embodiments, a first barrier rib 4622 may be provided on the inner surface of the first housing 462 so that the first heat exchange passage 40 or the second heat exchange passage 42 can be defined as a curved passage with a reciprocating bend using the first barrier rib 4622, thereby extending the length of the first heat exchange passage 40 or the second heat exchange passage 42 and slowing down the flow speed of the liquid in the first heat exchange passage 40 or the second heat exchange passage 42, thereby improving the heat exchange efficiency and improving the cooling effect. The first barrier rib 4622 is arranged along the lateral direction of the first heat exchange flow path 40, and multiple first barrier ribs 4622 are arranged at intervals along the axial direction.In this way, the first heat exchange flow path 40 can be divided into multiple parts along the axial direction, and gaps may be provided in the first barrier rib 4622, or in the connection between the first barrier rib 4622 and the thermal conductive partition 48, or in the connection between the first barrier rib 4622 and the first housing 462 so that the spaces before and after each first barrier rib 4622 can be connected.

[0252] In some embodiments, as shown in FIG. 8 , a plurality of second barrier ribs 4642 are provided on the inner surface of the second housing 464, and the plurality of second barrier ribs 4642 define a flow path between the second housing 464 and the thermally conductive partition 48 into a tortuous flow path with a reciprocating bend.

[0253] In these embodiments, a second barrier rib 4642 may be provided on the inner surface of the second housing 464 so that the first heat exchange passage 40 or the second heat exchange passage 42 can be defined as a curved passage with a reciprocating bend using the second barrier rib 4642, thereby extending the length of the first heat exchange passage 40 or the second heat exchange passage 42 and slowing down the flow speed of the liquid in the first heat exchange passage 40 or the second heat exchange passage 42, thereby improving the heat exchange efficiency and improving the cooling effect. The second barrier rib 4642 is arranged along the lateral direction of the first heat exchange flow path 40, and multiple second barrier ribs 4642 are arranged at intervals along the axial direction.In this way, the first heat exchange flow path 40 can be divided into multiple parts along the axial direction, and gaps may be provided in the second barrier rib 4642, or in the connection between the second barrier rib 4642 and the thermal conductive partition 48, or in the connection between the second barrier rib 4642 and the second housing 464 so that the spaces before and after each second barrier rib 4642 can be connected.

[0254] In some embodiments, as shown in Figures 1, 2, 3, 4, 5 and 6, the liquid treatment device further includes a liquid supply tank 5 connected to the liquid supply flow path and a fourth pumping device 6 disposed in the liquid supply flow path or the heating flow path.

[0255] In these embodiments, the liquid supply flow path may be connected to the user's home water pipe, and water may be supplied directly through the user's home water pipe, but in one possible embodiment, a liquid supply tank 5 may be provided to supply water to the liquid supply flow path via the liquid supply tank 5. By providing the liquid supply tank 5, water can be stored, and the product can be installed far away from the water pipe, making the use and installation location of the product more flexible and convenient. At the same time, a fourth pumping device 6 may be provided in the liquid supply flow path or the heating flow path so that the flow rate of water into the heating flow path via the fourth pumping device 6 can be controlled, thereby enabling control of the hot water temperature.

[0256] In some embodiments, the heat exchange device 4 includes a cooling device, the cooling device including a cooling box and a cooling liquid provided in the cooling box, and at least a portion of the liquid discharge flow path 32 is installed in the cooling liquid, or the heat exchange device 4 is an air-cooling device provided corresponding to the liquid discharge flow path 32.

[0257] In these embodiments, a cooling device may be provided, a cooling liquid may be provided in the cooling device, and a part or all of the liquid discharge passage 32 may be installed in the cooling liquid, thereby cooling the liquid in the liquid discharge passage 32 through the cooling liquid, where the cooling liquid may be water, or of course, the cooling liquid may be made of another liquid with good heat absorption. In another embodiment, the heat exchange device 4 may be provided as an air-cooling device, thereby cooling the liquid discharge passage 32 through the air-cooling device.

[0258] To achieve multiple cooling, the liquid in the liquid discharge flow path 32 may be cooled by using a cooling device consisting of the heat exchanger 4, an air cooling device, and a cooling box with cooling liquid in combination, or, of course, only one of the above cooling methods may be used for cooling.

[0259] In one possible embodiment, as shown in Figures 1 to 6, the liquid treatment device further includes a circuit board assembly 7, which may include a power board for supplying power and a control board for controlling the operation of the product.

[0260] Furthermore, as shown in Figures 1 to 6, the liquid treatment device includes a housing case 8, a heating assembly 2 mounted in the housing case 8, a circuit board assembly 7, a liquid supply assembly 1, and a liquid supply tank 5, and the housing case 8 may specifically consist of a base and a case lid.

[0261] In one possible embodiment, the liquid treatment device may specifically be a product such as an instant-heating electric kettle, a coffee pot, a soy milk maker, a juicer, etc. Of course, the liquid treatment device may also be other products than an instant-heating electric kettle, a coffee pot, a soy milk maker, or a juicer, such as a mixer, a health pot, etc.

[0262] As shown in Figures 8 to 18, an embodiment of the second aspect of the present application provides a heat exchange device 4 for use in the liquid treatment device shown in Figures 1 to 7, and as shown in Figures 1 to 7, the liquid treatment device includes a liquid supply assembly 1, a liquid discharge assembly 3, and a heating assembly 2 connected between the liquid supply assembly 1 and the liquid discharge assembly 3, and as shown in Figures 8 to 18, the heat exchange device 4 includes a first heat exchange passage 40 and a second heat exchange passage 42, and the second heat exchange passage 42 is connected between the heating assembly 2 and the liquid discharge assembly 3, and the first heat exchange passage 40 can exchange heat with the second heat exchange passage 42 to cool the liquid in the second heat exchange passage 42.

[0263] The heat exchange device 4 according to the embodiment of the present application can be used in a liquid treatment device, and specifically, the heat exchange device 4 incorporates a first heat exchange passage 40 and a second heat exchange passage 42. The second heat exchange passage 42 is connected between the heating assembly 2 and the liquid discharge assembly 3, and the first heat exchange passage 40 may be used to exchange heat with the second heat exchange passage 42 so as to cool the liquid in the second heat exchange passage 42. With this structure, liquid such as water heated by the heating assembly 2 can be cooled by heat exchange with the first heat exchange passage 40 in the second heat exchange passage 42 before being discharged via the liquid discharge assembly 3. The temperature of the high-temperature liquid heated by the heating assembly 2 when it flows through the second heat exchange passage 42 is higher than the temperature of the coolant in the first heat exchange passage 40. Thus, the first heat exchange passage 40 can continuously absorb heat from the liquid, such as water, in the second heat exchange passage 42 to realize heat exchange between the first heat exchange passage 40 and the second heat exchange passage 42. This allows the liquid, such as water, in the second heat exchange passage 42 to be cooled through heat exchange between the first heat exchange passage 40 and the second heat exchange passage 42. This structure utilizes the principle of heat exchange to cool the liquid, such as water, heated by the heating device. This cooling method is simple and easy to implement, thereby simplifying the product structure and reducing product costs. Of course, other cooling methods may also be used, such as air cooling using an electric fan. In this case, the heat exchanger 4 may be an air-cooling device.

[0264] In some embodiments, as shown in Figures 6 and 7, the heat exchange device 4 further includes a reservoir tank 44 connected to the inlet of the first heat exchange flow path 40 and the outlet of the first heat exchange flow path 40 to form a cooling circulation circuit.

[0265] In these embodiments, a liquid storage tank 44 may be additionally provided to form a circuit with the first heat exchange flow path 40 via the liquid storage tank 44, thereby constantly providing cooling power to cool the liquid, such as water, in the liquid discharge flow path 32. This structure allows the cooling circuit to be independent of the liquid flow path consisting of the liquid supply assembly 1, the heating assembly 2, and the liquid discharge assembly 3. Thus, the cooling circuit and the liquid flow path can be operated independently, allowing the cooling circuit to be turned on or off independently. Whether to turn on the cooling circuit can be determined according to actual demand during operation of the liquid treatment device. When the cooling circuit is not turned on, heated water can be directly discharged at a corresponding temperature, e.g., boiling water. When the cooling circuit is turned on, water can be first heated to a relatively high temperature, e.g., boiling, and then cooled to a relatively low temperature before being discharged. This structure allows the product to directly heat water and then discharge it, or to first heat and cool water before discharging it, thereby expanding product functionality and realizing product diversification, thereby enabling the product to better meet various user needs.

[0266] Additionally, the liquid treatment device further includes a temperature collection element disposed within the reservoir tank 44 for collecting the temperature of the liquid within the reservoir tank 44 .

[0267] In these embodiments, the temperature collection element is used to collect the temperature of the liquid in the reservoir tank 44 so that the flow rate of the cooling liquid in the first heat exchange flow path 40 can be controlled based on the temperature of the liquid in the reservoir tank 44 and further the cooling intensity can be controlled.

[0268] In some embodiments, as shown in Figures 15 and 16, the first heat exchange passage 40 is a tortuous passage with a reciprocating bend and / or the second heat exchange passage 42 is a tortuous passage with a reciprocating bend.

[0269] In these embodiments, the first heat exchange passage 40 and / or the second heat exchange passage 42 may be configured to be a curved passage with a reciprocating bend, thereby extending the length of the first heat exchange passage 40 and / or the second heat exchange passage 42 and improving the heat exchange effect of the heat exchange device 4. In one possible embodiment, the curved passage is a serpentine passage, or the curved passage is made up of a plurality of S-shaped passages connected to each other end to end, or the curved passage is made up of a plurality of N-shaped passages connected to each other end to end.

[0270] In some embodiments, the inlet of the first heat exchange flow path 40 and the inlet of the second heat exchange flow path 42 are located on the same side of the heat exchange device 4, and the outlet of the first heat exchange flow path 40 and the outlet of the second heat exchange flow path 42 are located on the same side of the heat exchange device 4.

[0271] In these embodiments, the temperature at the inlet of the first heat exchange flow path 40 is lower than the temperature at the outlet of the first heat exchange flow path 40, i.e., the temperature gradually increases from the inlet to the outlet of the first heat exchange flow path 40, so the heat exchange efficiency gradually decreases and the temperature at the inlet of the second heat exchange flow path 42 becomes higher than the temperature at the outlet of the second heat exchange flow path 42. Therefore, the inlet of the first heat exchange channel 40 and the inlet of the second heat exchange channel 42 may be located on the same side of the heat exchanger 4, for example, both on the right side. At the same time, the outlet of the first heat exchange channel 40 and the outlet of the second heat exchange channel 42 may be located on the same side of the heat exchanger 4, for example, both on the left side. In this way, the flow directions of the liquid in the first heat exchange channel 40 and the second heat exchange channel 42 are aligned, i.e., the inlet direction of the cooling liquid is aligned with the inlet direction of the hot water in the second heat exchange channel 42, and the outlet direction of the cooling liquid is also aligned with the outlet direction of the hot water in the second heat exchange channel 42. With this arrangement, the coldest cooling liquid can exchange heat with the hottest hot water, thereby increasing the heat exchange rate and cooling speed and thereby improving the heat exchange cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage 40 and the second heat exchange passage 42 do not coincide, the liquid at the inlet of the second heat exchange passage 42 will exchange heat with the liquid at the outlet of the first heat exchange passage 40, and the liquid at the outlet of the second heat exchange passage 42 will exchange heat with the liquid at the inlet of the first heat exchange passage 40.With such an installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0272] 8 to 14 , in some embodiments, the heat exchange device 4 includes an outer casing 46 and a heat conductive partition wall 48 provided in the outer casing 46, and the first heat exchange passage 40 and the second heat exchange passage 42 are provided on either side of the heat conductive partition wall 48. The outer casing 46 is provided with a first inlet corresponding to the first heat exchange passage 40 and communicating with the first heat exchange passage 40, and a first outlet communicating with the first heat exchange passage 40. The outer casing 46 is provided with a second inlet corresponding to the second heat exchange passage 42 and communicating with the second heat exchange passage 42, and a second outlet communicating with the second heat exchange passage 42.

[0273] In these embodiments, the heat exchange device 4 includes an outer casing 46 and a thermally conductive partition wall 48. The outer casing 46 is used to form an enclosed space, and the thermally conductive partition wall 48 is used to divide the interior space of the outer casing 46 into two parts, thereby forming two independent flow paths within the outer casing 46. In a specific example, one of the two flow paths divided by the thermally conductive partition wall 48 can be used as the first heat exchange flow path 40, and the other can be used as the second heat exchange flow path 42. The first heat exchange flow path 40 and the second heat exchange flow path 42 in the heat exchange device 4 having such a structure are divided by the thermally conductive partition wall 48, thereby making heat transfer between the two flow paths more convenient and efficient. Furthermore, the structure of the heat exchange device 4 having such a structure is relatively simple and easy to process, thereby reducing production costs. In addition, an inlet / outlet may be provided in the outer casing 46 corresponding to the first heat exchange flow path 40, and an inlet / outlet may be provided in the outer casing 46 corresponding to the second heat exchange flow path 42, so that liquid outside the heat exchange device 4 can enter the first heat exchange flow path 40 and the second heat exchange flow path 42 through the corresponding inlets / outlets.

[0274] In some embodiments, as shown in Figures 10 to 18, the outer casing 46 includes a first casing 462 shown in Figures 15 to 18, a second casing 464 attached to the first casing 462, a thermally conductive partition 48 attached to the connection between the first casing 462 and the second casing 464, a first sealing ring 466 provided between the thermally conductive partition 48 and the first casing 462 to seal between the thermally conductive partition 48 and the first casing 462, and a second sealing ring 468 provided between the thermally conductive partition 48 and the second casing 464 to seal between the thermally conductive partition 48 and the second casing 464.

[0275] In these embodiments, a sealed space may be formed between the first housing 462 and the second housing 464, and two flow paths may be partitioned therein by the thermally conductive partition 48. This configuration allows the outer housing 46 of the heat exchanger 4 to be divided into multiple members, thereby making each member relatively simple and reducing the processing difficulty and cost. When installed, the thermally conductive partition 48 may be attached to the connecting portion between the first housing 462 and the second housing 464, i.e., one portion of the thermally conductive partition 48 is attached within the first housing 462, and the other portion of the thermally conductive partition 48 is attached within the second housing 464. In one possible embodiment, a first sealing ring 466 may be provided between the first housing 462 and the thermally conductive partition wall 48 to achieve sealing between the first housing 462 and the thermally conductive partition wall 48 via the first sealing ring 466, and at the same time, a second sealing ring 468 may be provided between the second housing 464 and the thermally conductive partition wall 48 to achieve sealing between the second housing 464 and the thermally conductive partition wall 48 via the second sealing ring 468. The provision of the first sealing ring 466 and the second sealing ring 468 can prevent water leakage at the connection between the first housing 462 and the second housing 464.

[0276] In another possible embodiment as shown in Figures 10 to 18, the outer casing 46 includes a first casing 462 as shown in Figures 15 to 18, a second casing 464 attached to the first casing 462, and a third sealing ring (not shown) attached to the connection between the first casing 462 and the second casing 464 for sealingly connecting the first casing 462 and the second casing 464, and the thermally conductive partition 48 is attached within the first casing 462 or the second casing 464 (not shown in this embodiment).

[0277] In these embodiments, a sealed space may be formed between the first housing 462 and the second housing 464, and two flow paths may be partitioned therein via the thermally conductive partition 48. This arrangement allows the outer housing 46 of the heat exchanger 4 to be divided into multiple members, thereby making each member relatively simple and reducing the difficulty and cost of processing. The installation of a third sealing ring can seal the first housing 462 and the second housing 464, thereby preventing water leakage at the connection between the first housing 462 and the second housing 464.

[0278] In some embodiments, the first inlet and the second inlet are located on the same side of the outer housing 46, and the first outlet and the second outlet are located on the same side of the outer housing 46.

[0279] In these embodiments, the first inlet and the second inlet are located on the same side of the outer casing 46, and the first outlet and the second outlet are located on the same side of the outer casing 46, which aligns the liquid flow directions in the first heat exchange channel 40 and the second heat exchange channel 42, i.e., the inlet direction of the cooling liquid is aligned with the inlet direction of the hot water in the second heat exchange channel 42, and the outlet direction of the cooling liquid is aligned with the outlet direction of the hot water in the second heat exchange channel 42. With this arrangement, the coldest cooling liquid can exchange heat with the hottest hot water, which can speed up the cooling speed and therefore improve the cooling efficiency of the product. Conversely, if the inlet and outlet directions of the first heat exchange passage 40 and the second heat exchange passage 42 do not coincide, the liquid at the inlet of the second heat exchange passage 42 will exchange heat with the liquid at the outlet of the first heat exchange passage 40, and the liquid at the outlet of the second heat exchange passage 42 will exchange heat with the liquid at the inlet of the first heat exchange passage 40.With such an installation, the temperatures of the liquids exchanging heat with each other will be relatively close, resulting in poor heat exchange efficiency and a reduced product cooling effect.

[0280] In some embodiments, the outer surfaces of first housing 462 and / or second housing 464 are provided with heat dissipation fins.

[0281] In these embodiments, heat can be dissipated through the heat dissipation fins, thereby improving the heat dissipation efficiency of the heat exchange device 4. The heat dissipation fins may be provided on the first housing 462 or the second housing 464, or of course, the heat dissipation fins may be provided on both the first housing 462 and the second housing 464.

[0282] In some embodiments, as shown in Figures 15 and 16, a plurality of first barrier ribs 4622 are provided on the inner surface of the first housing 462, and the plurality of first barrier ribs 4622 define a flow path between the first housing 462 and the thermally conductive partition 48 into a tortuous flow path with a reciprocating bend.

[0283] In these embodiments, a first barrier rib 4622 may be provided on the inner surface of the first housing 462 so that the first heat exchange passage 40 or the second heat exchange passage 42 can be defined as a curved passage with a reciprocating bend using the first barrier rib 4622, thereby extending the length of the first heat exchange passage 40 or the second heat exchange passage 42 and slowing down the flow speed of the liquid in the first heat exchange passage 40 or the second heat exchange passage 42, thereby improving the heat exchange efficiency and improving the cooling effect. The first barrier rib 4622 is arranged along the lateral direction of the first heat exchange flow path 40, and multiple first barrier ribs 4622 are arranged at intervals along the axial direction.In this way, the first heat exchange flow path 40 can be divided into multiple parts along the axial direction, and gaps may be provided in the first barrier rib 4622, or in the connection between the first barrier rib 4622 and the thermal conductive partition 48, or in the connection between the first barrier rib 4622 and the first housing 462 so that the spaces before and after each first barrier rib 4622 can be connected.

[0284] In some embodiments, as shown in FIG. 8 , a plurality of second barrier ribs 4642 are provided on the inner surface of the second housing 464, and the plurality of second barrier ribs 4642 define a flow path between the second housing 464 and the thermally conductive partition 48 into a tortuous flow path with a reciprocating bend.

[0285] In these embodiments, a second barrier rib 4642 may be provided on the inner surface of the second housing 464 so that the first heat exchange passage 40 or the second heat exchange passage 42 can be defined as a curved passage with a reciprocating bend using the second barrier rib 4642, thereby extending the length of the first heat exchange passage 40 or the second heat exchange passage 42 and slowing down the flow speed of the liquid in the first heat exchange passage 40 or the second heat exchange passage 42, thereby improving the heat exchange efficiency and improving the cooling effect. The second barrier rib 4642 is arranged along the lateral direction of the first heat exchange flow path 40, and multiple second barrier ribs 4642 are arranged at intervals along the axial direction.In this way, the first heat exchange flow path 40 can be divided into multiple parts along the axial direction, and gaps may be provided in the second barrier rib 4642, or in the connection between the second barrier rib 4642 and the thermal conductive partition 48, or in the connection between the second barrier rib 4642 and the second housing 464 so that the spaces before and after each second barrier rib 4642 can be connected.

[0286] As shown in Figures 19, 20 and 22, a heat exchange box 10 according to an embodiment of the third aspect of the present application is used in a liquid heating appliance 20, and examples of the liquid heating appliance 20 include a kettle (electric kettle) and a water server. The heat exchange box 10 has a box portion 110 and a heat conductive partition wall 48, and can be understood by referring to the second heat exchange flow path 42 (specifically, the second heat exchange flow path 42 and / or the first flow path 42a and / or the second flow path 42b in the drawings; for ease of explanation, 42a and 42b will not be distinguished from each other in the description). In the following sections, either may be understood as the second heat exchange flow path 42. However, as will be understood, with regard to further definition of the second heat exchange flow path 42 (which may apply to the first flow path 42a and / or the second flow path 42b unless inconsistent), the first heat exchange flow path 40 is surrounded by the box portion 110 and the thermally conductive partition wall 48, and the second heat exchange flow path 42 and the first heat exchange flow path 40 are separated by the thermally conductive partition wall 48 and are configured to provide heat transfer between the medium in the second heat exchange flow path 42 and the medium in the first heat exchange flow path 40.

[0287] In the heat exchange box 10 according to the above embodiment of the present application, the second heat exchange passage 42 and the first heat exchange passage 40 are surrounded by the box part 110 and the thermally conductive partition 48, and the second heat exchange passage 42 and the first heat exchange passage 40 are separated by the thermally conductive partition 48. As such, the structure of the heat exchange box 10 is simple, the layout is reasonable, and the product is more integrated. Heat exchange between the cold and hot fluids is performed through the thermally conductive partition 48, so that the hot fluid can be quickly cooled to an appropriate temperature, the cold fluid can be preheated, and when heating the cold fluid, the energy required to heat it to boiling can be reduced. The high thermal conductivity of the thermal conductive partition 48 can be used to accelerate the heat transfer rate between the hot and cold fluids, shorten the heat exchange time, and improve the heat exchange effect of the heat exchange box 10. At the same time, the second heat exchange passage 42 and the first heat exchange passage 40 are separated by the thermal conductive partition, forming a partition-type heat exchange between the hot and cold fluids. This achieves heat exchange between the medium in the second heat exchange passage 42 and the medium in the first heat exchange passage 40, and ensures that they do not mix, that the hot fluid is not contaminated by the cold fluid, and improves the safety of the hot fluid.

[0288] In one embodiment of the present application, as shown in Figures 26, 27 and 28, the box portion 110 includes a box lid (specifically, please understand by referring to the second housing 464 and / or the first housing 462 in the drawings), the box lid is placed over the thermally conductive partition 48 and is hermetically connected to the thermally conductive partition 48, and the second heat exchange flow path 42 or the first heat exchange flow path 40 is surrounded by the box lid and the thermally conductive partition 48. First, the box lid is placed on the heat conductive partition 48 to form the second heat exchange passage 42 or the first heat exchange passage 40. In this way, under the same dimensional specifications, it is advantageous to increase the heat conduction area, and the heat exchange effect of the heat exchange box 10 is higher. Furthermore, the box lid is sealed and connected to the heat conductive partition 48 to prevent liquid leakage from the second heat exchange passage 42 or the first heat exchange passage 40 and mixing between the medium in the second heat exchange passage 42 and the medium in the first heat exchange passage 40, thereby ensuring that the hot fluid is not contaminated by the cold fluid and improving the safety and hygiene of the hot fluid.

[0289] As shown in FIG. 29, the second housing 464 and / or the first housing 462 has a pocket portion 1111, which is a chamber body having an opening at one end, in which flow guide ribs 170 are distributed, and a thermal conductive partition 48 covers the opening of the pocket portion 1111.

[0290] The second housing 464 and / or the first housing 462 have a pocket portion 1111, which is advantageous for increasing the volume of the second heat exchange passage 42 or the first heat exchange passage 40 and improving the heat exchange efficiency. In addition, flow guide ribs 170 are distributed within the pocket portion 1111, and by guiding the fluid through the flow guide ribs 170, the flow path of the fluid within the second heat exchange passage 42 or the first heat exchange passage 40 is extended, the fluid flow speed is reduced, and the heat exchange between the cold and hot fluids is more complete.

[0291] For example, as shown in FIG. 30, the second housing 464 and / or the first housing 462 have side walls and a bottom wall, which surround and define a chamber body having an opening, and a plurality of flow guide ribs 170 are distributed on the bottom wall, and the fluid flows along the flow guide ribs 170 within the pocket portion 1111, thereby extending the flow path of the fluid and allowing the fluid to stay in the heat exchange box 10 for a longer time, thereby making the heat exchange more complete and improving the heat exchange effect.

[0292] 20 , 38 , 39 , and 40 , the box unit 110 includes two box lids. For example, a second housing 464 and / or a first housing 462 are provided. A thermally conductive barrier 48 is disposed between the second housing 464 and the first housing 462. The second housing 464 and the first housing 462 are connected to and gripped by the thermally conductive barrier 48. As can be seen, the second heat exchange passage 42 is surrounded by one of the second housing 464 and the first housing 462 and the thermally conductive barrier 48, and the first heat exchange passage 40 is surrounded by the other of the second housing 464 and the first housing 462 and the thermally conductive barrier 48. The second housing 464 is connected to the first housing 462, and the thermally conductive barrier 48 is attached and fixed. This simplifies the product structure, facilitates assembly, and improves the assembly speed, thereby shortening the installation time.

[0293] For example, as shown in Figures 22, 23 and 24, the opening of the pocket portion 1111 of the second housing 464 faces the opening of the pocket portion 1111 of the first housing 462, and as shown in Figure 25, the thermal conductive partition 48 is located between the second housing 464 and the first housing 462 and is gripped by the second housing 464 and the first housing 462, and as can be seen, the thermal conductive partition 48 has two opposing side walls, the second heat exchange flow path 42 is surrounded by one side wall of the thermal conductive partition 48 and the second housing 464, and the first heat exchange flow path 40 is surrounded by the other side wall of the thermal conductive partition 48 and the first housing 462.

[0294] Of course, in another embodiment, at least one of the second housing 464 and the first housing 462 may be designed to be connected to the thermally conductive partition 48, so that the fixing effect of the thermally conductive partition 48 is better and the thermally conductive partition 48 is less likely to be displaced during the installation process.

[0295] 29, one of the second housing 464 and the first housing 462 is provided with a fitting portion 1112a, and the other is provided with a receiving portion 1112b, and the fitting portion 1112a is fitted into the receiving portion 1112b to position the second housing 464 and the first housing 462. For example, as shown in FIGS. 26, 27, and 28, the fitting portion 1112a includes lugs formed on the periphery of the second housing 464 and / or the first housing 462, and the receiving portion 1112b includes receiving recesses that fit the lugs, and the lugs are inserted into the receiving recesses to pre-position the second housing 464 and the first housing 462.

[0296] The fitting portion 1112a being fitted into the accommodating portion 1112b has the advantage of making the assembly operation convenient, and is convenient for quick and convenient positioning and pre-fixing between the second housing 464 and the first housing 462, improving the assembly convenience of the product. Furthermore, the fitting portion 1112a being fitted into the accommodating portion 1112b positions the second housing 464 and the first housing 462, improving the connection accuracy between the second heat exchange passage 42 and the first heat exchange passage 40, which is advantageous for improving the sealing performance of the second heat exchange passage 42 and the first heat exchange passage 40.

[0297] 42, 43, and 44, one of the second housing 464 and the first housing 462 is provided with a locking element 1113a, and the other is provided with a locking groove 1113b, and the locking element 1113a is locked into the locking groove 1113b. Specifically, the locking element 1113a is provided on the periphery of the second housing 464 and / or the first housing 462 and extends toward the opening of the second housing 464 and / or the first housing 462, and the locking element 1113a protrudes into the locking groove 1113b so that the second housing 464 is connected and fixed to the first housing 462. The locking between the locking element 1113a and the locking groove 1113b has the advantages of a simple structure and convenient installation, which can improve the assembly efficiency of the product and effectively ensure the connection reliability of the two box lids.

[0298] For example, the second housing 464 (first housing 462) has a bottom wall and a side wall, the bottom wall is transitionally connected to the side wall, the locking member 1113a has a connecting arm, the connecting arm is provided on the side wall of the second housing 464, a portion of the connecting arm abuts against the side wall of the second housing 464, and the second housing 464 and the first housing 462 are covered so that another portion of the connecting arm abuts against the side wall of the first housing 462, and in this way, the connecting arm abuts and stops the side wall of the second housing 464 and the side wall of the first housing 462 simultaneously, thereby avoiding misalignment of the second housing 464 and the first housing 462.

[0299] 42, 43, and 44, one of the second housing 464 and the first housing 462 has a protrusion, and a first hole 1114a is formed in the protrusion, and another of the second housing 464 and the first housing 462 has a second hole 1114b, which corresponds to the first hole 1114a, and connecting members (e.g., screws or bolts) are drilled into the first hole 1114a and the second hole 1114b to lock the second housing 464 and the first housing 462 together. This has a simple structure, is convenient to install, ensures connection reliability between the second housing 464 and the first housing 462, and reduces product costs.

[0300] In one specific example, as shown in FIG. 29, a second housing 464 has a protruding portion around its periphery, a protruding fitting portion 1112a is formed in the protruding portion, and a first hole 1114a is formed in the fitting portion 1112a; a first housing 462 has a protruding portion around its periphery, a storage portion 1112b (e.g., a storage tank) is formed in the protruding portion, and a second hole 1114b is formed in the bottom wall of the storage portion 1112b; the fitting portion 1112a is inserted into the storage portion 1112b, and the first hole 1114a and the second hole 1114b are docked together; and the first hole 1114a and the second hole 1114b are drilled sequentially by a connecting member, thereby connecting and fixing the second housing 464 and the first housing 462.

[0301] 31 and 32 , the box part 110 includes a box body 112, and the heat exchange box 10 has a plurality of thermally conductive partition walls 48 spaced apart. The box body 112 is hermetically connected to each of two adjacent thermally conductive partition walls 48, and together with the two adjacent thermally conductive partition walls 48, surrounds the second heat exchange passage 42 or the first heat exchange passage 40. The structure is relatively simple, assembly is relatively convenient, and manufacturing costs can be reduced. The two thermally conductive partition walls 48 transfer heat from both sides, further improving the heat exchange effect of the medium in the second heat exchange passage 42 or the medium in the first heat exchange passage 40.

[0302] 34, 35, and 36, the box body 112 is a double-open annular body 1121, and the annular body 1121 is provided with flow guide ribs 170, which are distributed throughout the area surrounded by the annular body 1121. Thermal conductive partition walls 48 are disposed on both sides of the annular body 1121, and the thermal conductive partition walls 48 on both sides cover the openings at both ends of the annular body 1121. The fact that the box body 112 is a double-open annular body 1121 is advantageous for achieving a larger volume with the same dimensions. The annular body 1121 is provided with flow guide ribs 170, which guide the fluid, thereby extending the fluid flow path in the second heat exchange channel 42 or the first heat exchange channel 40, slowing down the fluid flow speed, and improving the heat exchange effect.

[0303] In one embodiment of the present application, as shown in Figures 31, 32 and 33, the box part 110 includes two box lids and at least one box body 112, and the thermal conductive barrier 48 and the box body 112 are distributed between the two box lids, and the two box lids are connected to and gripped by the thermal conductive barrier 48 and the box body 112.

[0304] For example, the box part 110 includes a second housing 464, a first housing 462, and one box body 112, the opening of the second housing 464 faces the opening of the first housing 462, the box body 112 is located between the second housing 464 and the first housing 462, and the heat exchange box 10 has two heat conduction partition walls 48, one of which is located between the second housing 464 and the box body 112, and another heat conduction partition wall 48 is located between the first housing 462 and the box body 112, and thus the first flow path 42a is , the second housing 464 and the heat conductive partition 48 are surrounded by the second housing 462 and the heat conductive partition 48, the second flow path 42b is surrounded by the first housing 462 and the heat conductive partition 48, the first heat exchange flow path 40 is surrounded by the two heat conductive partitions 48 and the box body 112, and is provided within the first flow path 42a and the second flow path 42b to provide for the circulation of a cold fluid, and the first heat exchange flow path 40 provides for the circulation of a hot fluid. In this way, the first flow path 42a and the second flow path 42b simultaneously exchange heat with the first heat exchange flow path 40, further improving the cooling rate of the first heat exchange flow path 40.

[0305] Furthermore, as shown in Figures 34, 35 and 36, the second housing 464 is provided with a first inlet 11a and a third inlet 12a, and the first flow path 42a connects the first inlet 11a and the third inlet 12a, the first housing 462 is provided with a second inlet 11b and a fourth inlet 12b, and the second flow path 42b connects the second inlet 11b and the fourth inlet 12b, and the box body 112 is provided with a third communication port 13 and a fourth communication port 14. The first heat exchange passage 40 connects the third communication port 13 and the fourth communication port 14, the first inlet 11a and the third inlet 12a are provided in the bottom wall of the second housing 464, the second inlet 11b and the fourth inlet 12b are provided in the bottom wall of the first housing 462, and the third communication port 13 and the fourth communication port 14 are provided in the side wall of the box body 112, thus facilitating the piping connection of each communication port.

[0306] Alternatively, the box section 110 may include a second housing 464, a first housing 462, and one box body 112, the opening of the second housing 464 faces the opening of the first housing 462, the box body 112 is located between the second housing 464 and the first housing 462, the heat exchange box 10 has one heat conductive partition wall 48 located between the second housing 464 and the box body 112, the box body 112 is in communication with the first housing 462, and the second heat exchange flow path 42 is formed by the second housing 464 and the heat conductive partition wall 48. The first heat exchange passage 40 is surrounded by the heat conduction partition 48, the first housing 462 and the box body 112, and is located within the second heat exchange passage 42 to allow the hot fluid to circulate, while the first heat exchange passage 40 is used to allow the cold fluid to circulate. Since the volume of the first heat exchange passage 40 is larger than the volume of the second heat exchange passage 42, i.e., the content of the cold fluid in the heat exchange box 10 is greater than the content of the hot fluid, more cold fluid is exchanged with the hot fluid, ensuring sufficient heat exchange of the hot fluid.

[0307] Of course, in another embodiment, at least one of the second housing 464 and the first housing 462 may be designed to be connected to the thermally conductive partition 48 and the box body 112, in which case the fixing effect of the thermally conductive partition 48 and the box body 112 is better, and the thermally conductive partition 48 and the box body 112 are less likely to be displaced during the installation process.

[0308] Furthermore, an insert-fit coupling positioning is formed between adjacent box lids and the box body 112, or between adjacent box bodies 112 and the box body 112. This has the advantage of facilitating assembly operations, facilitating quick and convenient positioning and pre-fixing between the two box lids, improving the ease of assembly of the product, and positioning is achieved by inserting the fitting portion 1112a into the receiving portion 1112b, which improves the coupling precision between the two box lids and the box body 112 and is advantageous for improving the sealing of the second heat exchange channel 42 and the first heat exchange channel 40.

[0309] For example, as shown in FIGS. 34 and 35, the second housing 464 has a protrusion on its periphery, and a protruding fitting portion 1112a (e.g., a lug) is formed on the protrusion; the first housing 462 has a protrusion on its periphery, and a receiving portion 1112b (e.g., a receiving tank) is formed on the protrusion; the box body 112 has a protrusion on its periphery, and the protrusion has opposing sides, and one side of the protrusion facing the second housing 464 is formed with a receiving portion 1112b that fits the fitting portion 1112a, and one side of the protrusion facing the first housing 462 is formed with a receiving portion 1112b. In this way, when the second housing 464 is connected to the box body 112, the fitting portion 1112a of the second housing 464 is inserted into and positioned in the receiving portion 1112b of the box body 112, and when the first housing 462 is connected to the box body 112, the receiving portion 1112b of the first housing 462 is inserted into and positioned in the fitting portion 1112a of the box body 112, thereby realizing the positioning of the second housing 464, the first housing 462 and the box body 112.

[0310] Furthermore, the box body 112 is provided with a through-hole 1122 through which a connecting member passes. In this way, the two box lids are connected and attached, and the box body 112 is also connected and fixed, which enhances the connection stability and assembly precision of the three components, i.e., the two box lids and the box body 112, reduces the risk of liquid leakage, and further improves the reliability and sealing performance of the product.

[0311] For example, as shown in Figures 34 and 35, the second housing 464 has a protrusion on its periphery, and a protruding fitting 1112a (e.g., a lug) is formed on the protrusion, and a first hole 1114a is formed in the fitting 1112a; the first housing 462 has a protrusion on its periphery, and a receiving portion 1112b (e.g., a receiving tank) is formed on the protrusion, and a second hole 1114b is formed in the bottom wall of the receiving portion 1112b; the box body 112 has a protrusion on its periphery, and the protrusion has opposite sides, and one side of the protrusion facing the second housing 464 is formed with the receiving portion 1112b that fits with the fitting 1112a; and the box body A through-hole 1122 is formed in the protruding portion of the body 112. Thus, when the second housing 464 is connected to the box body 112, the fitting portion 1112a of the second housing 464 is inserted into and positioned in the accommodating portion 1112b of the box body 112. When the first housing 462 is connected to the box body 112, the accommodating portion 1112b of the first housing 462 is inserted into and positioned in the fitting portion 1112a of the box body 112. At the same time, the first hole 1114a, the second hole 1114b and the through-hole 1122 are docked, and the first hole 1114a, the second hole 1114b and the through-hole 1122 are drilled sequentially by the connecting member, thereby connecting and fixing the second housing 464, the first housing 462 and the box body 112.

[0312] In one embodiment of the present application, as shown in Figures 25 and 36, the heat exchanger box 10 has a sealing ring 120 (e.g., a rubber ring or a silicone ring), which abuts against the box portion 110 and the thermal conductive partition 48 and is hermetically connected to the box portion 110 and the thermal conductive partition 48, thereby further achieving sealing between the box portion 110 and the thermal conductive partition 48, making it less likely that leakage will occur between the box portion 110 and the thermal conductive partition 48, and effectively preventing turbulence between the medium in the second heat exchange flow path 42 and the medium in the first heat exchange flow path 40.

[0313] 30 , a sealing layer 130 (e.g., silicone ketone rubber) is formed between the box portion 110 and the thermally conductive partition wall 48, and the sealing layer 130 bonds and fixes the box portion 110 and the thermally conductive partition wall 48. In this way, the sealing between the box portion 110 and the thermally conductive partition wall 48 is ensured, and the sealing layer 130 bonds and fixes the box portion 110 and the thermally conductive partition wall 48. This further prevents misalignment between the box portion 110 and the thermally conductive partition wall 48 and improves the reliability of the connection between the box portion 110 and the thermally conductive partition wall 48.

[0314] 29 , at least one of the box part 110 and the thermally conductive partition 48 is provided with a groove 140, and at least a portion of the sealing ring 120 or the sealing layer 130 is fitted into the groove 140. The groove 140 provides a mounting portion for the sealing ring 120 or the sealing layer 130, thereby preventing the sealing ring 120 or the sealing layer 130 from moving and avoiding sealing problems caused by misalignment of the sealing ring 120 or the sealing layer 130. This improves the positional accuracy of the sealing ring 120 or the sealing layer 130, thereby improving the accuracy of the sealing connection between the sealing ring 120 or the sealing layer 130 and the box part 110 and the thermally conductive partition 48, and further improving the sealing reliability.

[0315] In some embodiments, the sealing ring 120 or the sealing layer 130 is disposed around the edge of the thermally conductive partition 48. In this way, the reliability of the seal is ensured and the sealing ring 120 or the sealing layer 130 is prevented from contaminating the medium in the second heat exchange passage 42 or the medium in the first heat exchange passage 40, thereby improving safety and hygiene.

[0316] In one embodiment of the present application, as shown in Figures 37, 38 and 41, a turbulent flow structure 150 is configured in at least one of the box part 110 of the heat exchanger box 10 and the thermally conductive partition wall 48. The turbulent flow structure 150 can slow down the flow rate of the medium, allowing for more efficient heat exchange between the medium in the second heat exchange passage 42 and the medium in the first heat exchange passage 40, improving the heat exchange effect, and the turbulent flow structure 150 can disturb the medium, thereby making the temperatures inside the second heat exchange passage 42 and the first heat exchange passage 40 more uniform and ensuring a better heat exchange effect.

[0317] It is worth mentioning that, as shown in FIG. 30, the turbulence structures 150 may be designed to be arranged along the fluid flow direction, or may be designed to be mutually inclined to the fluid flow direction; in one embodiment, as shown in FIG. 46, the turbulence structures 150 are designed to be perpendicular to the fluid flow direction, thus the turbulence effect is better.

[0318] In some embodiments, as shown in Figures 47, 51, 52 and 53, the thermally conductive barrier 48 is configured with a protrusion structure 151a and / or a recess structure 151b, and the protrusion structure 151a and / or the recess structure 151b are formed as a turbulent flow structure 150 on the thermally conductive barrier 48. The structure of the thermally conductive barrier 48 is simple, easy to process, and advantageous for reducing costs. In addition, the protrusion structure 151a and / or the recess structure 151b increase the surface area of ​​the thermally conductive barrier 48, thereby further increasing the heat transfer area between the two medium flow paths and improving heat exchange.

[0319] For example, as shown in Figures 54 and 55, some local regions on the thermally conductive partition 48 protrude outward to form multiple convex structures 151a, while other local regions are recessed inward to form multiple concave structures 151b. Concave structures 151b are formed between adjacent convex structures 151a, or the convex structures 151a and the concave structures 151b are alternately distributed, thereby giving the thermally conductive partition 48 a generally wavy or serpentine shape.

[0320] In another embodiment, as shown in Figures 56 and 57, the thermal conductive barrier 48 is provided with a plurality of protruding ribs formed as a turbulence structure 150, which not only plays a turbulent role but also strengthens the strength and rigidity of the thermal conductive barrier 48 using the ribs; furthermore, ribs are provided on two opposite sides of the thermal conductive barrier 48, so that the fluids on both sides of the thermal conductive barrier 48 can be disturbed by the ribs, improving the heat exchange effect; furthermore, as shown in Figure 40, the ribs are shaped like elongated rods, and a plurality of ribs are distributed in a row and spaced apart on the thermal conductive barrier 48, so that the ribs also have a certain flow-guiding effect, further enhancing the function of the thermal conductive barrier 48.

[0321] 45 and 46, the heat exchange box 10 is divided into a plurality of spaces via heat-conducting partitions 48, where the number of spaces is two or more, and flow guide ribs 170 are distributed within the spaces, and the flow guide ribs 170 define curved flow paths 160 within the spaces. In this way, the flow path of the fluid in the second heat exchange path 42 or the first heat exchange path 40 is extended, the flow speed of the fluid is reduced, and the heat exchange between the medium in the second heat exchange path 42 and the medium in the first heat exchange path 40 is more complete, thereby improving the heat exchange effect.

[0322] In some embodiments, as shown in Figures 51 and 52, the flow guide rib 170 is provided with one or more first turbulence ribs 152, and the first turbulence ribs 152 protrude into the flow path 160. In this way, the flow guide rib 170 guides the flow and further slows down the flow velocity of the fluid, improving the heat exchange effect.

[0323] In some embodiments, there is a gap between the flow guide rib 170 and the thermally conductive partition wall 48, thus providing a larger heat exchange area and improving the heat exchange efficiency.

[0324] For example, the flow guide ribs 170 are provided in the box portion 110. Specifically, the flow guide ribs 170 are provided in the second housing 464 and / or the first housing 462. The second housing 464 and / or the first housing 462 have a bottom wall and a side wall. The thermally conductive partition walls 48 are spaced apart from the bottom wall and abut against the side wall so that the second heat exchange passage 42 or the first heat exchange passage 40 is surrounded by the thermally conductive partition walls 48, the bottom wall, and the side wall. A plurality of flow guide ribs 170 are provided on the bottom wall. The height of the flow guide ribs 170 is lower than the height of the side wall. This allows fluid to flow through gaps between the flow guide ribs 170 and the thermally conductive partition walls 48, thereby obtaining a larger heat transfer area and allowing the fluid to more fully contact the thermally conductive partition walls 48 for heat exchange.

[0325] In some embodiments, as shown in FIG. 30, the box portion 110 of the heat exchanger box 10 has a sealing barrier 113, and the space is surrounded by the sealing barrier 113 and the thermally conductive partition wall 48. The sealing barrier 113 is provided with one or more second turbulence ribs 153, and the second turbulence ribs 153 protrude into the flow path 160, which, while guiding the flow, further slows down the flow speed of the fluid and improves the heat exchange effect.

[0326] 26 and 29, the flow guide ribs 170 define a serpentine flow path 160 within the space, which further extends the flow path of the fluid in the second heat exchange flow path 42 or the first heat exchange flow path 40, thereby allowing for more efficient heat exchange between the medium in the second heat exchange flow path 42 and the medium in the first heat exchange flow path 40 and improving the heat exchange effect.

[0327] In one embodiment of the present application, as shown in Figures 22 and 23, the second heat exchange passage 42 and the first heat exchange passage 40 on both sides of the thermal conduction partition 48 are positioned opposite each other, which can be understood as the second heat exchange passage 42 and the first heat exchange passage 40 corresponding to each other in the projection direction. In this way, the structural layout inside the heat exchange box 10 is more reasonable, which is advantageous for making full use of the second heat exchange passage 42 and the first heat exchange passage 40, and the heat conduction area between the second heat exchange passage 42 and the first heat exchange passage 40 is larger, making the heat exchange more efficient.

[0328] A mixed flow distribution is formed between the second heat exchange passage 42 and the first heat exchange passage 40 on both sides of the heat conduction partition 48, thus increasing the heat exchange efficiency between the second heat exchange passage 42 and the first heat exchange passage 40.

[0329] Of course, in other embodiments, the second heat exchange passage 42 and the first heat exchange passage 40 may be designed to form a parallel flow heat exchange, depending on specific needs.

[0330] In one embodiment of the present application, as shown in Figures 48, 49 and 50, the heat exchange box 10 has a first communication port 11, a second communication port 12, a third communication port 13 and a fourth communication port 14, and as shown in Figures 51 and 52, the second heat exchange flow path 42 connects the first communication port 11 and the second communication port 12, the first heat exchange flow path 40 connects the third communication port 13 and the fourth communication port 14, and the first communication port 11 and the third communication port 13 are positioned opposite each other, and / or the second communication port 12 and the fourth communication port 14 are positioned opposite each other.

[0331] In one embodiment of the present application, the thermally conductive barrier 48 is a metal member, for example, an aluminum plate or a stainless steel plate, and thus the thermally conductive barrier 48 has the advantages of good thermal conductivity and low cost.

[0332] In one embodiment of the present application, the box part 110 of the heat exchanger box 10 is a heat-conducting member, for example, the box part 110 is made of a material having a heat conduction function, for example, the box part 110 is made of an aluminum plate or a stainless steel plate, which enables the heat exchanger box 10 to exchange heat with the outside and is advantageous in further reducing the temperature of the heat exchanger box 10, thereby allowing the thermal fluid to dissipate heat more quickly and improving the heat exchange efficiency.

[0333] In one embodiment of the present application, as shown in FIG. 34, fins 180 are provided on the surface of the box portion 110 of the heat exchange box 10, thereby further improving the ability of heat exchange between the heat exchange box 10 and the outside.

[0334] An embodiment of the fourth aspect of the present application provides a liquid heating appliance 20, as shown in Figures 59, 60 and 63, which includes a liquid discharge nozzle 34, a liquid supply tank 5, and a waterway system connected to the liquid discharge nozzle 34 and the liquid supply tank 5, and the heat exchange box 10 in any one of the above technical means is formed as part of the waterway system.

[0335] The liquid heating appliance 20 according to the above embodiment of the present application has all of the above beneficial technical effects by providing the heat exchange box 10 in any one of the above technical means, and therefore further explanation will be omitted here.

[0336] In detail, as shown in Figures 61, 62 and 63, the liquid heating appliance 20 further includes a housing case 8, a circuit board assembly, a water vapor isolation box assembly 230, etc. The housing case 8 is used to house the liquid supply tank 5 and the water channel system, the circuit board assembly includes a power supply assembly 221 and a control assembly 222, and the water vapor isolation box assembly 230 is used to isolate water vapor generated during the heating process.

[0337] In one embodiment of the present application, as shown in FIG. 64 , the waterway system has one heat exchange box 10. Specifically, the heat exchange box 10 has a first medium flow path and a second medium flow path. The first medium flow path is used for cold water circulation, and the second medium flow path is used for hot water circulation. The heat exchange box 10 has a first communication port 11, a second communication port 12, a third communication port 13, and a fourth communication port 14. The second heat exchange flow path 42 is connected to the first communication port 11 and the second communication port 12. is connected to the first communication port 11, cold water flows into the second heat exchange flow path 42 from the first communication port 11 and flows out along the second communication port 12, the first heat exchange flow path 40 connects the third communication port 13 and the fourth communication port 14, hot water flows into the first heat exchange flow path 40 from the fourth communication port 14 and flows out along the third communication port 13, the liquid supply tank 5 communicates with the first communication port 11 to supply cold water, and the liquid discharge nozzle 34 communicates with the third communication port 13 to allow the cooled hot water to flow out.

[0338] The difference from the above embodiment is that the waterway system of this embodiment has multiple heat exchange boxes 10, the second heat exchange flow paths 42 of the multiple heat exchange boxes 10 are connected in series, and the first heat exchange flow paths 40 of the multiple heat exchange boxes 10 are connected in series. By increasing the number of heat exchange boxes 10, the fluid flow path can be extended, allowing for sufficient heat exchange between the hot and cold fluids.

[0339] In one embodiment of the present application, the position of at least a part of the waterway system is higher than the highest water level position of the liquid supply tank 5, which effectively prevents the liquid from directly flowing out of the liquid discharge nozzle 34 due to the connector principle, thereby improving the reliability of the product.

[0340] Furthermore, the position of at least one of the first communication port 11, the second communication port 12, the third communication port 13 and the fourth communication port 14 of the heat exchanger box 10 is higher than the highest water level position of the liquid supply tank 5, and by controlling the positions of the first communication port 11, the second communication port 12, the third communication port 13 and / or the fourth communication port 14 of the heat exchanger box 10, it is easy to ensure that they are higher than the highest water level position of the liquid supply tank 5, making assembly simpler and reducing the assembly difficulty, effectively preventing water from directly flowing out of the liquid discharge nozzle due to the connector principle, and improving the reliability of the product.

[0341] In some embodiments, the heat exchange box 10 is vertically oriented, as shown in FIGS.

[0342] In some embodiments, the heat exchange box 10 is positioned horizontally, as shown in FIG.

[0343] In some embodiments, the heat exchange box 10 is disposed at an angle.

[0344] In one embodiment of the present application, the water channel system further includes a heating assembly 2 and a water distribution box 212, the water distribution box 212 is connected to the liquid supply tank 5 and the second heat exchange flow path 42 of the heat exchange box 10, and the liquid supply tank 5 supplies water to the second heat exchange flow path 42 through the water distribution box 212, the water distribution box 212 is connected to the second heat exchange flow path 42 and the heating assembly 2, and the second heat exchange flow path 42 supplies water to the heating assembly 2 through the water distribution box 212, and the first heat exchange flow path 40 is connected to the heating assembly 2 and the liquid discharge nozzle 34.

[0345] 67, the water supply box 212 has a first storage chamber and a second storage chamber, and the first storage chamber communicates with the liquid supply tank 5 and the second heat exchange passage 42 so that the liquid supply tank 5 and the second heat exchange passage 42 communicate with each other through the water supply box 212, thereby realizing that the cold water in the liquid supply tank 5 is discharged into the first storage chamber and then discharged into the second heat exchange passage 42 through the first storage chamber, and the cold water from the liquid supply tank 5 is fully heat-exchanged with the hot water in the first heat exchange passage 40 in the second heat exchange passage 42, thereby realizing that the hot water in the first heat exchange passage 40 is cooled to an appropriate temperature, and the cold water in the second heat exchange passage 42 is preheated, and the second heat exchange passage 42 is The passage 42 communicates with the first storage chamber and the second storage chamber, i.e., the first storage chamber, the second storage chamber and the second heat exchange passage 42 form a circulation circuit, and the water in the second heat exchange passage 42 is returned to the second storage chamber after sufficient heat exchange. The heating assembly 2 communicates with the second storage chamber, and the heating assembly 2 sufficiently heats the cold water to boiling. Since the cold water has been pre-heated, the heating time and heating power of the heating assembly 2 are reduced, which is advantageous to reducing the energy consumption of the product and making the product more energy-efficient. The first heat exchange passage 40 communicates with the liquid discharge nozzle 34, so that the hot water after sufficient heat exchange is finally discharged through the liquid discharge nozzle 34.

[0346] Furthermore, the first storage chamber and the second storage chamber are interconnected, and thus the first storage chamber can replenish water to the second storage chamber, avoiding a shortage of water from the second heat exchange passage 42, ensuring that the second storage chamber has enough water to provide to the heating assembly 2, avoiding the heating assembly 2 from heating up empty, and improving the stability of the product.

[0347] Furthermore, the flow between the first and second storage chambers is controlled so that it is conducted from the first storage chamber to the second storage chamber and blocked from the second storage chamber to the first storage chamber. In this way, it is possible to prevent the preheated cold water from returning to the first storage chamber and exchanging heat with the cold water in the first storage chamber, which on the one hand prevents the preheated cold water from cooling rapidly and causing heat loss, and on the other hand prevents the cold water in the first storage chamber from rising in temperature. After the cold water in the first storage chamber flows into the second heat exchange passage 42, a sufficient temperature difference is maintained between the cold water in the second heat exchange passage 42 and the hot water in the first heat exchange passage 40, ensuring the heat exchange amount and improving the heat exchange effect.

[0348] In some embodiments, the water channel system includes a first pump 213 (e.g., a water pump) for driving the liquid from the water distribution box 212 to the second heat exchange passage 42. Specifically, the first pump 213 is connected to the first chamber of the water distribution box 212 and the second heat exchange passage 42, and is configured to drive the cold water from the first chamber to the second heat exchange passage 42. In this way, the efficiency and reliability of the fluid flow can be improved, the problem of fluid clogging can be avoided, and the high heat exchange efficiency of the heat exchange box 10 can be ensured.

[0349] In some embodiments, the waterway system includes a second pump 214 (e.g., a water pump) that drives the liquid from the water distribution box 212 to the heating assembly 2. Specifically, the second pump 214 is in communication with the second chamber of the water distribution box 212 and the second heat exchange passage 42, and is configured to drive cold water from the second heat exchange passage 42 to the second chamber. In this way, the efficiency and reliability of the fluid flow can be improved, the risk of fluid clogging and the heating assembly 2 running dry can be avoided, and product safety can be improved.

[0350] At least a portion of one or more of the water distribution box 212, the heating assembly 2, the first pump 213, and the second pump 214 of the water conduit system is located higher than the highest water level position of the liquid supply tank 5. In this way, the water conduit system, the liquid discharge nozzle 34, and the liquid supply tank 5 are prevented from forming a communicator, preventing water from directly flowing out of the liquid discharge nozzle 34, and improving product reliability.

[0351] In one embodiment of the present application, as shown in Figures 19 to 67, the heat exchange box 10 has a box lid (specifically including a second housing 464 and / or a first housing 462), a box body 112 and a thermally conductive partition 48.

The second heat exchange passage 42 is surrounded by the box lid and the thermally conductive partition wall 48, and the first heat exchange passage 40 is surrounded by two thermally conductive partition walls 48 and the box body 112. The second heat exchange passage 42 is distributed on both sides of the first heat exchange passage 40. The second heat exchange passage 42 is used to circulate cold water, and the first heat exchange passage 40 is used to circulate hot water. Heat is exchanged between the cold water in the second heat exchange passage 42 and the hot water in the first heat exchange passage 40 via the thermally conductive partition wall 48. In this way, the cold water and the hot water are separated by the thermally conductive partition wall 48 and heat exchanged between them via the thermally conductive partition wall 48. This allows the hot water to be quickly cooled to a temperature desired by the user and reduces the energy required to heat the cold water until it boils when it enters the heating assembly 2.

[0353] The second heat exchange passage 42 and the first heat exchange passage 40 correspond to each other in the projection direction, thereby making full use of the second heat exchange passage 42 and the first heat exchange passage 40 and increasing the heat exchange area.

[0354] The inlet direction of the second heat exchange passage 42 is the same as the outlet direction of the first heat exchange passage 40, i.e., the second heat exchange passage 42 and the first heat exchange passage 40 are distributed in a counterflow manner. In this way, a lower hot water temperature can be obtained using the counterflow heat exchange method.

[0355] Furthermore, the box lid and the thermal conduction partition 48, and the box body 112 and the thermal conduction partition 48 are sealed together, respectively, to avoid leakage between the cold and hot water streams and the heat exchange box 10, and improve the safety and hygiene of hot water for drinking.

[0357] In another embodiment, the heat exchanger box 10 has a sealing layer 130, which is located between the box lid and the thermally conductive partition 48 and adhesively fixes the box lid and the thermally conductive partition 48, and the sealing layer 130 is located between the box body 112 and the thermally conductive partition 48 and adhesively fixes the box body 112 and the thermally conductive partition 48.

[0358] Furthermore, a ring-shaped recessed groove 140 is provided on the box lid, and at least a portion of the sealing ring 120 and / or sealing layer 130 is fitted into the recessed groove 140 to avoid misalignment of the sealing ring 120 and / or sealing layer 130 and ensure the reliability of the seal.

[0359] Furthermore, the inside of the heat exchange box 10 is divided into multiple spaces via heat-conducting partitions 48, and flow-guiding ribs 170 are distributed within the spaces, and the flow-guiding ribs 170 divide curved water flow paths 160 within the spaces to extend the flow distance of the water flow.

[0360] In some embodiments, the flow guide ribs 170 are provided on the box lid. Specifically, the box lid has a pocket portion 1111, which is a chamber body having an opening at one end, the flow guide ribs 170 are distributed within the pocket portion 1111, and the thermal conductive partition 48 covers the opening of the pocket portion 1111. Furthermore, the flow guide ribs 170 are provided on the box lid and have a certain gap between them and the thermal conductive partition 48, which facilitates assembly of the box lid and the thermal conductive partition 48 and increases the heat exchange area.

[0361] In some embodiments, the flow guide ribs 170 are provided on the box body 112. Specifically, the box body 112 is a ring-shaped body 1121 that is open at both ends. The flow guide ribs 170 are provided on the ring-shaped body 1121, and the flow guide ribs 170 on the ring-shaped body 1121 are distributed in the area surrounded by the ring-shaped body 1121. Thermal conductive partitions 48 are arranged on both sides of the ring-shaped body 1121, and the thermal conductive partitions 48 on both sides cover the openings at both ends of the ring-shaped body 1121. Furthermore, the flow guide ribs 170 are provided on the box body 112, and there is a certain gap between them and the thermal conductive partitions 48, which facilitates assembly of the box body 112 and the thermal conductive partitions 48 and increases the heat exchange area.

[0362] In some embodiments, the flow guide ribs 170 are provided on the thermally conductive partition wall 48. Specifically, the thermally conductive partition wall 48 has two opposing sides, and a plurality of flow guide ribs 170 are distributed on each side.

[0363] Furthermore, a turbulent structure 150 is provided in the water flow path 160, which increases the turbulence of the water, thereby increasing the convective heat exchange coefficient between the water and the thermally conductive partition wall 48 and increasing the amount of heat exchange.

[0364] The turbulence structures 150 may be designed along the water flow direction or may be mutually inclined to the water flow direction, and in yet another embodiment, the turbulence structures 150 are designed to be perpendicular to the water flow direction, thus achieving a better turbulence effect.

[0365] In some embodiments, the turbulence structure 150 includes turbulence ribs that are provided on the box lid and / or box body 112 and protrude into the second heat exchange flow path 42 and / or the first heat exchange flow path 40.

[0366] In some embodiments, a turbulence structure 150 is provided in the thermally conductive partition 48, which can increase turbulence, increase the surface area of ​​the thermally conductive partition 48, and further increase the heat exchange area between the second heat exchange passage 42 and the first heat exchange passage 40.

[0367] Specifically, the thermally conductive partition wall 48 is configured with a convex structure 151a and / or a concave structure 151b, and the convex structure 151a and / or the concave structure 151b are formed as the turbulent flow structure 150 on the thermally conductive partition wall 48. Alternatively, the thermally conductive partition wall 48 may be designed to have a plurality of rib plate structures, and the rib plate structures are formed as the turbulent flow structure 150 on the thermally conductive partition wall 48.

[0368] In any one of the above embodiments, the thermally conductive barrier 48 includes an aluminum plate or a stainless steel plate.

[0369] In any one of the above embodiments, the box cover and the box body 112 are made of a highly heat-conductive material, and further, fins 180 are provided on the outside of the box cover to increase heat exchange with the outside through the fins 180.

[0370] The present application further provides a liquid heating appliance 20 having the heat exchange box 10. Exemplary liquid heating appliances 20 include a pot, a kettle, a water server, a water purifier, and the like.

[0371] In the following, the liquid heating appliance 20 will be taken as an example of an instant-heat electric kettle. The liquid heating appliance 20 includes a liquid discharge nozzle 34, a liquid supply tank 5, and a waterway system connected to the liquid discharge nozzle 34 and the liquid supply tank 5, and the heat exchange box 10 is formed as part of the waterway system.

[0372] In detail, the waterway system includes a heating assembly 2 capable of rapidly heating water, a water pump, a circuit board assembly (exemplarily, the circuit board assembly includes a power supply assembly 221 and a control assembly 222), and a water distribution box 212. A heat exchange box 10 is connected in series to the hot water supply piping. Furthermore, the heat exchange box 10 is a plate-type heat exchange box 10.

[0373] In the instant heating electric kettle of the present application, the heat exchange box 10 includes a second heat exchange passage 42 and a first heat exchange passage 40. More specifically, the water distribution box 212 has a first storage chamber and a second storage chamber. The first storage chamber communicates with the liquid supply tank 5 and the second heat exchange passage 42 so that the liquid supply tank 5 and the second heat exchange passage 42 communicate with each other via the water distribution box 212. This allows the cold water in the liquid supply tank 5 to be discharged into the first storage chamber and then discharged to the second heat exchange passage 42 via the first storage chamber. The cold water from the liquid supply tank 5 is sufficiently heat exchanged with the hot water in the first heat exchange passage 40 in the second heat exchange passage 42, thereby cooling the hot water in the first heat exchange passage 40 to an appropriate temperature. The second heat exchange passage 42 The cold water in the second heat exchange passage 42 is preheated, and the second heat exchange passage 42 communicates with the first and second storage chambers, i.e., the first storage chamber, the second storage chamber and the second heat exchange passage 42 form a circulation circuit, and the water in the second heat exchange passage 42 is returned to the second storage chamber after sufficient heat exchange. The heating assembly 2 communicates with the second storage chamber, and the heating assembly 2 sufficiently heats the cold water to boiling. Since the cold water has been preheated, the heating time and heating power of the heating assembly 2 are reduced, which is advantageous to reducing the energy consumption of the product and making the product more energy-efficient. The first heat exchange passage 40 communicates with the liquid discharge nozzle 34, so that the hot water after sufficient heat exchange is finally discharged through the liquid discharge nozzle 34.

[0374] In summary, in this embodiment, the liquid supply tank 5 - the first storage chamber of the water distribution box 212 - the second heat exchange passage 42 - the second storage chamber of the water distribution box 212 form the water supply pipeline of the water channel system, and the second storage chamber of the water distribution box 212 - the heating assembly 2 - the first heat exchange passage 40 - the liquid discharge nozzle 34 form the hot water supply pipeline of the water channel system, which simultaneously supplies water to the second heat exchange passage 42 and the heating assembly 2 through the water distribution box 212 and receives circulating water from the second heat exchange passage 42, thereby making it easier to connect the piping between each component in the water channel system and making the connecting piping inside the product simpler and less messy.

[0375] Furthermore, at least a part of the heat exchange box 10 is higher than the highest water level position of the liquid supply tank 5, specifically, the hot water supply connection port of the heat exchange box 10 is higher than the highest water level of the liquid supply tank 5, ensuring that the water in the liquid supply tank 5 does not flow out directly from the hot water supply connection port of the heat exchange box 10 due to the connector principle.

[0376] In some embodiments, when the position of the heat exchange box 10 is lower than the maximum water level of the liquid supply tank 5, a portion of the piping connected to the communication port of the heat exchange box 10 is designed to be higher than the maximum water level of the liquid supply tank 5.

[0377] In some embodiments, the heat exchange box 10 is positioned vertically within the product, and in further embodiments, the heat exchange box 10 is positioned horizontally within the product.

[0378] The water pump includes a first pump 213 that drives liquid from the water distribution box 212 to the second heat exchange flow path 42 and a second pump 214 that drives liquid from the water distribution box 212 to the heating assembly 2, the first pump 213 being a non-return pump that can return water in the water distribution box 212.

[0379] In the heat exchange box and the liquid heating appliance according to the above-mentioned embodiment of the present application, a first medium flow path and a second medium flow path are formed in the heat exchange box, and the first medium flow path and the second medium flow path are separated by a heat conduction plate. Thus, the structure of the heat exchange box is simple, the layout is reasonable, and the product is more integrated. Heat exchange between the cold and hot fluids is performed through the heat conduction plate, so that the hot fluid can be quickly cooled to an appropriate temperature, and the cold fluid can be preheated. When heating the cold fluid, the energy required to heat it to boiling can be reduced. The high thermal conductivity of the heat conduction plate can be used to accelerate the heat transfer rate between the hot and cold fluids, shorten the heat exchange time, and improve the heat exchange effect of the heat exchange box. At the same time, the first and second medium flow paths are separated by the heat conduction plate, forming a partition-type heat exchange between the hot and cold fluids. This achieves heat exchange between the medium in the first medium flow path and the medium in the second medium flow path, and ensures that they do not mix and the hot fluid is not contaminated by the cold fluid, thereby improving the safety of the hot fluid.

[0380] As shown in FIG. 72, an embodiment of the fifth aspect of the present application provides a liquid heating appliance including a water channel system 30, a temperature measurement system 70, and a control assembly 222.

[0381] Specifically, as shown in FIG. 72 , the waterway system 30 includes a liquid discharge nozzle 34, a heat exchange box 10, a flow parameter adjusting member 320, and a heating assembly 2, wherein the heat exchange box 10 has a first heat exchange passage 40 and a second heat exchange passage 42, the first heat exchange passage 40 exchanges heat with the second heat exchange passage 42, the heating assembly 2 has a water inlet 331 and a water outlet 332, the water inlet 331 communicates with the first heat exchange passage 40, and the second heat exchange passage 42 is connected to the water outlet 332 and the liquid discharge nozzle 34, and the flow parameter adjusting member 320 is suitable for adjusting the liquid flow parameters in the waterway system 30.

[0382] In one operating state of the waterway system 30, the heating assembly 2 heats water. The heated water is discharged through the water outlet 332 into the second heat exchange passage 42, flows through the second heat exchange passage 42, and is then discharged along the liquid outlet nozzle 34 for consumption by the user. Because the first heat exchange passage 40 exchanges heat with the second heat exchange passage 42, the water heated by the heating assembly 2 and discharged can exchange heat with materials in the first heat exchange passage 40 as it flows through the second heat exchange passage 42. This allows the water heated by the heating assembly 2 to be effectively cooled before being discharged along the liquid outlet nozzle 34, allowing the liquid heating appliance to provide water at different temperatures and meet the user's hot water needs. This structure also allows the heating assembly 2 to heat water to a specific temperature to remove most bacteria and ensure food safety. Compared to related technologies that heat water to a specified temperature in a non-boiling stage to provide hot water at multiple temperatures, this design meets the user's water temperature needs at different temperature stages while ensuring sterilization effects, balancing the user's hot water temperature needs with food safety needs. Furthermore, the water that has been heat-exchanged and heated in the first heat exchange flow path 40 of the heat exchange box 10 can be supplied to the heating assembly 2, realizing heat recovery for the product and improving the operating energy efficiency of the product.

[0383] 72, the temperature measurement system 70 is connected to the water channel system 30 and measures the temperature of the water channel system 30. The control assembly 222 may be a chip, a circuit board, etc., and may specifically be a microprocessor. The control assembly 222 is connected to the temperature measurement system 70, the heating assembly 2, and the flow parameter adjusting member 320, and is adapted to control the heating power of the heating assembly 2 and / or the liquid flow parameters in the water channel system 30 based on the temperature information fed back by the temperature measurement system 70. In this way, the water channel system temperature adjustment control is achieved, which can improve the stability and accuracy of the hot water temperature of the product, so that the actual hot water temperature of the product can better meet the hot water temperature demand, and improve the user experience of the product.

[0384] In some embodiments, as shown in FIG. 73 , the temperature measurement system 70 includes a first temperature measurement element 710 that collects the temperature of the water inlet 331 and responds by emitting a corresponding signal based on the collected results, and a control assembly 222 that is connected to the first temperature measurement element 710 and controls the heating power of the heating assembly 2 and / or the liquid flow parameters (e.g., flow rate, flow velocity, etc.) of the water inlet 331 based on at least the signal from the first temperature measurement element 710. Since the water absorbed by the heating assembly 2 may be heat-exchanged water from the first heat exchange flow path 40, the temperature may be relatively high and change in real time. A first temperature measuring element 710 is provided to collect the water temperature of the water inlet 331 of the heating assembly 2, and the heating power of the heating assembly 2 and / or the liquid flow parameters of the water inlet 331 (e.g., flow rate, flow velocity, etc.) may be controlled accordingly. In this way, the compatibility between the heat supply amount and the heat energy demand of the heating assembly 2 may be improved, the sterilization effect of the heating assembly 2 on the liquid may be better ensured, for example, the water in the heating assembly 2 may be better heated to boiling, improving food safety, and the heat exchange efficiency in the heat exchange box 10 may be more accurate, thereby realizing the accuracy and stability of the hot water temperature supplied by the liquid discharge nozzle 34.

[0385] For example, the first temperature measuring element 710 is disposed at the water inlet 331 of the heating assembly 2, and a portion of the first temperature measuring element 710 is inserted into the water inlet 331 to collect the water temperature in the water inlet 331, or is disposed outside the water inlet 331 to collect the pipe temperature of the water inlet 331 to reflect the water temperature in the water inlet 331 based on the pipe temperature of the water inlet 331. In this way, by controlling the heating power of the heating assembly 2 and / or the liquid flow parameters of the water inlet 331 based on the water temperature of the water inlet 331, more accurate temperature control can be achieved, thereby improving the accuracy and stability of the hot water temperature supplied from the liquid discharge nozzle 34.

[0386] For example, a pump (specifically, this can be understood by referring to the second pump 214 in FIG. 77) or a valve may be provided upstream of the heating assembly 2 in the waterway system 30. Specifically, for example, a pump or valve may be provided connected to the water inlet 331, or the pump or valve may be centrally connected to the water inlet 331 via a pipe. The control assembly 222 controls liquid flow parameters such as the flow rate and flow velocity of the water inlet 331 by adjusting the operating parameters of the pump (e.g., flow rate, rotation speed, frequency, etc.) or the opening degree of the valve. By providing the pump or valve upstream of the water inlet 331, the high-temperature water heated by the heating assembly 2 does not pass through the pump or valve, thereby better ensuring the service life of the pump or valve. Of course, in another embodiment, a pump or valve may be provided downstream of the heating assembly 2 in the waterway system 30 as needed, which can similarly achieve the purpose of adjusting liquid flow parameters such as the flow rate and flow velocity of the water inlet 331.

[0387] In some embodiments, as shown in FIG. 73 , the temperature measurement system 70 includes a second temperature measurement element 720 that collects the temperature of the water outlet 332 and responds by emitting a corresponding signal based on the collected result, and the control assembly 222 is connected to the second temperature measurement element 720, and the control assembly 222 controls the heating power of the heating assembly 2 and / or the liquid flow parameters (e.g., flow rate, flow velocity, etc.) of the water inlet 331 based on at least the signal from the second temperature measurement element 720. Since the water absorbed by the heating assembly 2 may be heat-exchanged water from the first heat exchange flow path 40, the temperature may be relatively high and change in real time. A second temperature measuring element 720 is provided to collect the water temperature of the water outlet 332 of the heating assembly 2, and the heating power of the heating assembly 2 and / or the liquid flow parameters (e.g., flow rate, flow velocity, etc.) of the water inlet 331 may be controlled accordingly. In this way, the heat supply amount of the heating assembly 2 can be better matched with the heat energy demand received, and the sterilization effect of the heating assembly 2 on the liquid can be better guaranteed, for example, the water in the heating assembly 2 can be better heated to boiling, improving food safety, and the heat exchange efficiency in the heat exchange box 10 can be more accurate, thereby realizing the accuracy and stability of the hot water temperature supplied by the liquid discharge nozzle 34.

[0388] For example, the second temperature measuring element 720 is provided at the water outlet 332 of the heating assembly 2, and a portion of the second temperature measuring element 720 is inserted into the water outlet 332 to collect the water temperature in the water outlet 332, or is located outside the water outlet 332 to collect the pipe temperature of the water outlet 332 to reflect the water temperature in the water outlet 332 based on the pipe temperature of the water outlet 332. In this way, by controlling the heating power of the heating assembly 2 and / or the liquid flow parameters of the water inlet 331 based on the water temperature of the water outlet 332, more accurate temperature control can be achieved, thereby improving the accuracy and stability of the hot water temperature supplied from the liquid discharge nozzle 34.

[0389] Further, as shown in FIG. 74, the control assembly 222 is provided with a first comparator 510, one input end of which is connected to the output end of the second temperature measuring element 720 to obtain the temperature of the water outlet 332, and the other input end of the first comparator 510 is accessed to a preset temperature threshold, and when the temperature of the water outlet 332 does not exceed the preset temperature threshold, the output signal of the first comparator 510 is configured to increase the heating power of the heating assembly 2 and / or reduce the flow rate of the water inlet 331.

[0390] Specifically, for example, if the temperature of the water outlet 332 is equal to or lower than a preset temperature threshold, the first comparator 510 issues a signal to trigger an increase in the heating power of the heating assembly 2 and / or trigger the flow parameter adjusting member 320 to reduce the flow rate of the water inlet 331, so as to correspondingly increase the temperature of the liquid discharged from the heating assembly 2 to better meet the sterilization demand and improve food safety. If the temperature of the water outlet 332 is higher than the preset temperature threshold, the first comparator 510 does not output a signal to maintain the current heating power of the heating assembly 2 and / or the current flow rate of the water inlet 331. Of course, if the temperature of the water outlet 332 is higher than the preset temperature threshold, the output signal of the first comparator 510 may be designed to trigger a decrease in the heating power of the heating assembly 2 and / or trigger the flow parameter adjusting member 320 to increase the flow rate of the water inlet 331.

[0391] The preset temperature threshold is 90°C to 100°C, and for products suitable for use at altitudes of less than 1000m, the preset temperature threshold is further set to 95°C to 100°C. In this way, the sterilization effect of the product is more guaranteed.

[0392] As can be understood, the preset temperature threshold may be the boiling temperature of the liquid to be heated (e.g., water), or a temperature substantially lower than the boiling temperature. The specific values ​​of the preset temperature threshold in this embodiment are not limited to 90°C to 100°C and 95°C to 100°C described in the above examples. In fact, a person skilled in the art can flexibly adjust the specific values ​​of the preset temperature threshold according to specific sterilization needs. Although no examples will be given here, it should be understood that any of these values ​​falls within the scope of protection of this embodiment without departing from the concept of this design.

[0393] Further, as shown in FIG. 75, the control assembly 222 is provided with a second comparator 520, one input end of which is connected to the output end of the second temperature measuring element 720 to obtain the temperature of the water outlet 332, and the other input end of the second comparator 520 is accessed for the boiling temperature, and when the temperature of the water outlet 332 is at least the boiling temperature, the output signal of the second comparator 520 is configured to reduce the heating power of the heating assembly 2 and / or increase the flow rate of the water inlet 331.

[0394] Specifically, for example, if the temperature of the water outlet 332 is above the boiling temperature (e.g., 100°C) for a long period of time, the second comparator 520 will emit a signal to trigger a reduction in the heating power of the heating assembly 2 and / or trigger the flow parameter adjusting member 320 to increase the flow rate of the water inlet 331, so as to meet the sterilization demand and reduce the energy consumption of the product; if the temperature of the water outlet 332 is lower than the boiling temperature, the second comparator 520 will not output a signal to maintain the current heating power of the heating assembly 2 and / or the current flow rate of the water inlet 331; of course, if the temperature of the water outlet 332 is lower than the boiling temperature, the output signal of the second comparator 520 may be designed to trigger an increase in the heating power of the heating assembly 2 and / or trigger the flow parameter adjusting member 320 to reduce the flow rate of the water inlet.

[0395] For example, the boiling temperature is 90°C to 100°C, thus ensuring a better sterilization effect of the product. The specific value of the boiling temperature in this embodiment is not limited to 90°C to 100°C as described in the above examples. In fact, a person skilled in the art can flexibly adjust the specific value of the boiling temperature according to the environmental pressure and the specific boiling temperature requirements. Although no examples are given here, it should be understood that any of these are within the scope of protection of this embodiment without departing from the concept of this design.

[0396] 73 , the temperature measurement system 70 includes a third temperature measuring element 730, which collects the temperature of the liquid discharge nozzle 34 and responds by issuing a corresponding signal based on the collected temperature, and the control assembly 222 is connected to the third temperature measuring element 730, which controls the liquid flow parameters (e.g., flow rate, flow velocity, etc.) in the first heat exchange channel 40 based on at least the signal from the third temperature measuring element 730. This feedback adjustment has a higher response timeliness, allowing the water temperature of the liquid discharge nozzle 34 to be quickly adjusted to the target value, and more accurately stabilizing the hot water temperature of the product.

[0397] For example, the third temperature measuring element 730 is provided in the liquid discharge nozzle 34, and a portion of the third temperature measuring element 730 is inserted into the liquid discharge nozzle 34 to collect the water temperature inside the liquid discharge nozzle 34, or is located outside the liquid discharge nozzle 34 to collect the pipe temperature of the liquid discharge nozzle 34 to reflect the water temperature inside the liquid discharge nozzle 34 based on the pipe temperature of the liquid discharge nozzle 34. In this way, by controlling the liquid flow parameters in the first heat exchange passage 40 based on the water temperature of the liquid discharge nozzle 34, more accurate temperature control can be achieved, thereby improving the accuracy and stability of the hot water temperature supplied by the liquid discharge nozzle 34.

[0398] Furthermore, the liquid heating apparatus further includes a command receiving element configured to obtain a target temperature command or a target level command, and the control assembly 222 is connected to the command receiving element, and the control assembly 222 controls the flow rate in the first heat exchange flow path 40 based on the temperature from the liquid discharge nozzle 34 of at least the third temperature measuring element 730 and the target temperature command or the target level command from the command receiving element.

[0399] Specifically, for example, if the temperature of the liquid discharge nozzle 34 is lower than the temperature specified by the target water temperature command or the target level command, the flow rate in the first heat exchange passage 40 is reduced, thereby correspondingly reducing the cooling rate in the second heat exchange passage 42, allowing the temperature of the liquid discharge nozzle 34 to quickly rise to the temperature specified by the target water temperature command or the target level command. If the temperature of the liquid discharge nozzle 34 is higher than the temperature specified by the target water temperature command or the target level command, the flow rate in the first heat exchange passage 40 is increased, thereby correspondingly reducing the cooling rate in the second heat exchange passage 42, allowing the temperature of the liquid discharge nozzle 34 to quickly cool to the temperature specified by the target water temperature command or the target level command. This feedback adjustment provides more timely and accurate response, allowing the water temperature of the liquid discharge nozzle 34 to be quickly adjusted to the target value, and more accurately stabilizing the hot water temperature of the product.

[0400] More specifically, the command receiving element is, for example, a signal interface, suitable for receiving a target temperature command or a target level command from a liquid heating appliance operation panel or a terminal device.

[0401] More specifically, a pump (specifically, this can be understood by referring to the first pump 213 in FIG. 77) or a valve may be provided upstream or downstream of the first heat exchange passage 40 in the waterway system 30. For example, a pump or a valve may be provided connected to the first heat exchange passage 40, or the pump or valve may be centrally connected to the first heat exchange passage 40 via a pipe. Specifically, for example, the pump or valve may be connected in series with the first heat exchange passage 40, or the valve may be connected in parallel with the first heat exchange passage 40 to form a bypass adjustment of the flow rate or flow velocity of the first heat exchange passage 40. In this way, the control assembly 222 can control the flow rate of the first heat exchange passage 40 by adjusting the operating parameters of the pump (e.g., flow rate, rotation speed, frequency, etc.) or the opening degree of the valve, thereby achieving the purpose of adjusting the flow rate of the first heat exchange passage 40 by the control assembly 222.

[0402] In some embodiments, the temperature measurement system 70 includes a fourth temperature measurement element 740, which collects the supply water temperature of the first heat exchange flow path 40 and responds by issuing a corresponding signal based on the collected results, and the control assembly 222 is connected to the fourth temperature measurement element 740, and the control assembly 222 controls the flow parameters of the first heat exchange flow path 40 based on at least the signal from the fourth temperature measurement element 740.

[0403] For example, the fourth temperature measuring element 740 is provided at the water supply end of the first heat exchange passage 40, and a portion of the fourth temperature measuring element 740 is inserted into the first heat exchange passage 40 to collect the water temperature in the first heat exchange passage 40, or the fourth temperature measuring element 740 is located outside the first heat exchange passage 40 to collect the pipe temperature of the first heat exchange passage 40 to reflect the water temperature in the first heat exchange passage 40 based on the pipe temperature of the first heat exchange passage 40. In this way, by controlling the liquid flow parameters (e.g., flow rate, flow velocity, fluid temperature, etc.) in the first heat exchange passage 40 based on the water temperature of the first heat exchange passage 40, more accurate temperature control can be achieved, thereby improving the accuracy and stability of the hot water temperature of the liquid discharge nozzle 34.

[0404] For example, the heat exchange load of the heat exchange box 10 can be calculated based on the temperature of the water outlet 332 of the heating assembly 2 and the target water temperature command or the target level command. In this embodiment, the water supply temperature of the first heat exchange flow path 40 is collected, and parameters such as the flow rate, flow velocity, and fluid temperature in the first heat exchange flow path 40 are adjusted based on the water supply temperature of the first heat exchange flow path 40, thereby correspondingly controlling the heat exchange capacity of the heat exchange box 10 to reach the required heat exchange load. This enables the temperature of the liquid discharge nozzle 34 to be controlled to meet the target water temperature command or the target level command requirements, and the temperature of the liquid discharge nozzle 34 to be maintained at a good stability. This is also beneficial to maintaining high energy-efficient operation of the heat exchange box 10, thereby improving the energy efficiency of the product.

[0405] For example, a pump (specifically, see the first pump 213 in FIG. 77) or a valve may be provided upstream or downstream of the first heat exchange passage 40 in the waterway system 30. The flow rate and flow rate in the first heat exchange passage 40 can be controlled by controlling the pump's operating parameters (e.g., flow rate, rotation speed, frequency, etc.) or the valve's opening degree, thereby achieving the purpose of adjusting the flow rate and flow rate in the first heat exchange passage 40 via the control assembly 222. For example, if the supply water temperature of the first heat exchange passage 40 is low under a certain heat exchange load, the flow rate or flow rate in the first heat exchange passage 40 may be controlled to decrease, thereby improving the compatibility between the heat exchange supply conditions and the heat exchange load, and controlling the temperature of the liquid discharge nozzle 34 to meet the user's demand and stabilizing the temperature of the liquid discharge nozzle 34. When the water supply temperature of the first heat exchange channel 40 is high under a certain heat exchange load, the flow rate or speed within the first heat exchange channel 40 can be increased or the water supply source of the first heat exchange channel 40 can be switched to reduce the water supply temperature of the first heat exchange channel 40, thereby improving the compatibility between the heat exchange supply rate and the heat exchange load, and controlling the temperature of the liquid discharge nozzle 34 to meet the user's needs and stabilizing the temperature of the liquid discharge nozzle 34. This design improves the compatibility between the water supply temperature, flow rate, flow speed, etc. of the first heat exchange channel 40 and the heat exchange load, maintaining efficient heat exchange between the first heat exchange channel 40 and the second heat exchange channel 42. This can reduce the driving force demand of the product to a certain extent and achieve energy conservation and reduced emissions of the product. It can also reduce the heat exchange area demand between the first heat exchange channel 40 and the second heat exchange channel 42 to a certain extent, which is advantageous for product compactness.

[0406] In some embodiments, as shown in FIG. 76 , the liquid heating appliance further includes a fifth temperature measuring element 80 connected to the control assembly 222, which collects the ambient temperature and feeds the collected ambient temperature back to the control assembly 222. In this way, the control assembly 222 can predict the heat transferred to the air based on the ambient temperature, and can more accurately determine and calibrate the measurement accuracy of each temperature measuring point in the water channel system 30 to match the ambient heat dissipation rate, thereby making the temperature control adjustment of the water channel system 30 more accurate and more accurately predicting the hot water temperature at the liquid discharge nozzle 34, so that the actual hot water temperature can more accurately meet the user's desired target temperature.

[0407] For example, when the target hot water temperature is higher than the ambient temperature and the temperature difference is relatively large, the hot water temperature may be increased by taking into account the effect of the temperature difference on the accuracy of the hot water temperature, for example, by increasing the hot water temperature by 0.1°C to 1°C to reduce the temperature difference between the temperature of the hot water actually received by the user and the target hot water temperature.

[0408] Furthermore, for example, when the ambient temperature is relatively low, the amount of heat dissipated in the process from the water outlet 332 of the heating assembly 2 to the liquid discharge nozzle 34 can be predicted based on the ambient temperature, thereby more accurately predicting the heat exchange load of the heat exchange box 10 and achieving more accurate heat dissipation cooling for the hot water in the heat exchange box 10.

[0409] 77 , the flow parameter adjusting member 320 includes a first pump 213. The first pump 213 is connected to the first heat exchange flow path 40 and is electrically connected, wirelessly or by wire, to a control assembly 222. The control assembly 222 adjusts the operating parameters of the first pump 213 to control the liquid flow parameters in the first heat exchange flow path 40. Using the first pump 213 to adjust the liquid flow parameters in the first heat exchange flow path 40 can more accurately control the heat exchange efficiency in the heat exchange box 10, thereby more accurately controlling the hot water temperature at the liquid discharge nozzle 34. The water flow rate and flow velocity of the heating assembly 2 can be better matched to the heating efficiency of the heating assembly 2, thereby ensuring a more reliable sterilization effect and more accurately adjusting and controlling the hot water temperature at the liquid discharge nozzle 34, while also achieving energy-saving and reduced product emissions.

[0410] In some embodiments, as shown in FIG. 77 , the flow parameter adjusting member 320 includes a second pump 214. The second pump 214 is connected to the water inlet 331 and is electrically connected, wirelessly or by wire, to the control assembly 222, which adjusts the operating parameters of the second pump 214 to control the liquid flow parameters of the water inlet 331. Using the second pump 214 to adjust the liquid flow parameters of the water inlet 331 allows for more accurate control of the heat exchange efficiency in the heat exchange box 10, thereby more accurately controlling the hot water temperature of the liquid outlet nozzle 34 and better matching the water flow rate and speed of the heating assembly 2 to the heating efficiency of the heating assembly 2, thereby ensuring a more reliable sterilization effect and more accurately adjusting and controlling the hot water temperature of the liquid outlet nozzle 34, while also achieving energy conservation and reduced product emissions.

[0411] In some embodiments, as shown in FIG. 77, the water channel system further includes a water distribution box 212, and the first pump 213 of the flow parameter adjusting member 320 is connected to the water distribution box 212 and is suitable for driving the liquid to flow between the first heat exchange passage 40 and the water distribution box 212. In this way, the first pump 213 can provide a driving force for the liquid to flow between the water distribution box 212 and the first heat exchange passage 40, thereby forming forced heat exchange between the first heat exchange passage 40 and the second heat exchange passage 42, which has higher heat exchange efficiency and better controllability of the heat exchange amount. Thus, the water temperature and temperature stability of the liquid discharge nozzle 34 can be more accurately controlled.

[0412] 77, the water channel system further includes a water distribution box 212, and a second pump 214 of the flow parameter adjusting member 320 is connected to the water distribution box 212 and is adapted to drive the liquid to flow from the water distribution box 212 to the water inlet 331. In this way, the second pump 214 can provide the driving force for the liquid to flow between the water distribution box 212 and the water inlet 331 of the heating assembly 2, so that the water flow rate and flow velocity of the heating assembly 2 can be better adapted to the heating efficiency of the heating assembly 2 and the sterilization effect can be more assured. Furthermore, the hydraulic driving action can be used to meet the driving force demand and flow rate regulation demand of the water channel system 30, and the flow rate and flow velocity in the second heat exchange channel 42 can be controlled, thereby better ensuring the hot water supply efficiency demand of the liquid discharge nozzle 34 and more accurately controlling the water temperature and temperature stability of the liquid discharge nozzle 34.

[0413] The water channel system 30 uses the water distribution box 212 to relay and allocate the water flow, which can achieve better allocation of the water flow within the water channel system 30, more rational and sequential adjustment and control of cold and hot water, better achieve the allocation of water temperature and flow rate adjustment control at each position within the water channel system 30, ensure more accurate hot water temperature at the liquid discharge nozzle 34, improve heat recovery for the product, and make the product more energy-efficient.

[0414] In some embodiments, as shown in FIG. 77 , the water channel system 30 includes a water distribution box 212 and a liquid supply tank 5. The water distribution box 212 functions to connect the connections and allocate water flow. For example, the water distribution box 212 has a first connection port, a second connection port, a third connection port, and a fourth connection port, where the first connection port is connected to a first pump 213, the second connection port is connected to a second pump 214, the third connection port is connected to the liquid supply tank 5, and the fourth connection port is connected to the first heat exchange flow path 40. A first chamber and a second chamber are formed inside the water distribution box 212, and the first chamber connects the first pump 213 and the liquid supply tank 5, and the second chamber connects the second pump 214 and the first heat exchange flow path 40. A conduit may be formed between the first chamber and the second chamber from the first chamber to the second chamber, for example, by a check valve or a conduit / channel with a certain height. This not only allows water to be supplied from the liquid supply tank 5 to the heating assembly 2, but also provides a connection between the first heat exchange channel 40 and the heating assembly 2 (i.e., a central connection between the first heat exchange channel 40 and the heating assembly 2 via the water distribution box 212). Water discharged from the first heat exchange channel 40 enters the heating assembly 2 and is heated, thereby achieving heat recovery and improving energy conservation. Furthermore, a conduit is provided between the first chamber and the second chamber from the second chamber to the first chamber. This prevents the hot water in the second chamber from returning to the first chamber, reducing heat loss and improving energy conservation.

[0415] In one operating condition of the product, water supplied from the liquid supply tank 5 enters the first chamber, and the first pump 213 drives the water in the first chamber into the first heat exchange flow path 40 and, after being discharged from the first heat exchange flow path 40, returns to the second chamber of the water distribution box 212. The second pump 214 drives the water in the second chamber into the heating assembly 2.
