Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, and in particular to a water dispenser and its control method. Background Technology

[0002] An instant hot water dispenser is a device that provides hot water instantly without requiring the user to wait. Unlike traditional preheated hot water dispensers, instant hot water dispensers provide fresh hot water immediately, avoiding repeated boiling and eliminating energy waste caused by the hot water tank's heat preservation stage.

[0003] In practical applications, although instant water dispensers can use electricity to heat room temperature water to a specified temperature, they are difficult to provide high-temperature clean water that meets user needs. Furthermore, the water flow rate of instant water dispensers is usually determined by the power of the heating module and the temperature difference between the inlet and outlet. Due to the power limitations of the household power supply system, the water flow rate of instant water dispensers at the high-temperature water setting is generally small, especially in winter when the water temperature is low, which makes it take longer for users to get water. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in related technologies.

[0069] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0074] The following is combined Figures 1-10 The water dispenser and its control method provided in this invention will be described in detail through specific embodiments and application scenarios.

[0075] In the first aspect, such as Figure 1 As shown, an embodiment of the present invention provides a water dispenser, including: a water purification module 10, a heat storage module 1, a heating module 2, a pumping component 4, and a control module;

[0076] The inlet of the water purification module 10 is connected to the water supply system 5; the inlet of the heat storage module 1 is connected to the outlet of the water purification module 10; the inlet of the heating module 2 is connected to the outlet of the heat storage module 1, and the outlet of the heating module 2 can be selectively connected to the outlet 6 of the heat storage module 1 or the water dispenser via the valve control 3; the pumping component 4 is used to drive the water flow from the heat storage module 1 to the heating module 2; the control module is connected to the water purification module 10, the valve control 3, the heating module 2 and the pumping component 4 respectively.

[0077] The control module is used to acquire water intake signals and target water intake parameters. Based on the water intake signals, it controls the water purification module 10 to start operation and controls the valve control 3 to connect the heating module 2 and the water outlet 6. Based on the target water intake parameters, it controls the working state of the heating module 2 and the pumping component 4 so that the water output parameters of the water outlet 6 are adapted to the target water intake parameters.

[0078] Understandably, the water supply system 5 can be a tap water system or a water tank, capable of stably supplying water to the inlet of the water purification module 10.

[0079] The water purification module 10 can use a water treatment filter cartridge to filter impurities in the raw water supplied by the water supply system 5. The water treatment filter cartridge includes at least one of the following: polypropylene melt-blown filter cartridge (PP cotton), activated carbon filter cartridge, ceramic filter cartridge, ultrafiltration (UF) filter cartridge, and reverse osmosis (RO) membrane.

[0080] The heat storage module 1 typically includes a heat exchanger and a heat storage material. A heat exchange channel is formed on the inner side of the heat exchanger, and the heat storage material is in contact with the outer side of the heat exchanger. The heat storage material can be a solid-liquid phase change material, cast aluminum, water, etc. The water purification module 10 is connected to the heating module 2 through the heat exchange channel. The heat storage module 1 can be equipped with a heater, which can use electric heating to heat the heat storage material, thereby energizing it. After energizing, the temperature of the heat storage material rises, maintaining the temperature within the heat exchange channel within a preset range for a certain period, thus preheating the cold water passing through the heat exchange channel.

[0081] The heating module 2 can be an electric heating element or a plate heat exchanger. The heating module 2 is constructed with a heating channel to heat the water flowing through the heating channel. The heating module 2 can adaptively adjust the heating power according to the water temperature at the outlet 6.

[0082] The pumping component 4 is a hot water pump with a flow control function to control the flow rate of the pumped water. When the water dispenser is in the water dispensing mode, the pumping component 4 controls the water supplied by the water supply system 5 to pass through the water purification module 10, the heat storage module 1, and the heating module 2 in sequence, and then flow out from the water outlet 6. Among them, the pumping component 4 controls the flow rate of the pumped water, the heat storage module 1 ensures the preheating temperature of the water, and the heating module 2 further controls the heating power of the water. These three components work together to ensure the flow rate and temperature of the water output from the water outlet 6.

[0083] The control module can be a PLC controller or a microcontroller. Since the heat storage module 1 includes a heat exchanger and a heat storage material, a heat exchange channel is formed on the inner side of the heat exchanger, and the heat storage material is in contact with the outer side of the heat exchanger. The water outlet of the heating module 2 can be connected to the water inlet of the heat exchange channel or the middle of the heat exchange channel, so as to supply the hot water output by the heating module 2 to the heat exchange channel of the heat storage module 1. Then, based on the heat exchange of the wall of the heat exchange channel, the heat energy of the hot water is stored in the heat storage material.

[0084] Specifically, before the user takes water, or during the user's free time (when there is no water taking operation), the water outlet of the heating module 2 can be connected to the heat exchange channel of the heat storage module 1 through the valve control 3, so as to use hot water to store and charge the heat storage module 1.

[0085] By setting the outlet of the heating module 2 to be selectively connected to the heat storage module 1 or the water outlet 6 via the valve control 3, the water dispenser can operate in either heat storage mode or water dispensing mode. In heat storage mode, the water dispenser can use the hot water output from the heating module 2 to store heat in the heat storage module 1, without the need for additional equipment to provide the heat energy required for heat storage in the heat storage module 1. This not only reduces costs but also provides good energy-saving and environmental protection effects. In water dispensing mode, since the heat storage module 1 has already completed heat storage, the heat storage module 1 can be used to preheat the clean water output from the water purification module 10, and then the heating module 2 can be used to heat the preheated clean water, ensuring that the water outlet 6 outputs a large flow of high-temperature clean water.

[0086] Furthermore, the valve control 3 has a first state and a second state; when the valve control 3 is in the first state, the water outlet of the heating module 2 is connected to the water outlet 6 through the valve control 3; when the valve control 3 is in the second state, the water outlet of the heating module 2 is connected to the heat storage module 1 through the valve control 3, so as to form a circulating water path based on the heat storage module 1 and the heating module 2.

[0087] Understandably, valve control 3 can be configured as a two-position three-way solenoid directional valve, and the water dispenser can be configured with a water dispensing button, an operation panel, and other human-machine interaction modules. The human-machine interaction module and the control module are electrically connected, and the control module and valve control 3 are electrically connected.

[0088] The human-machine interface module receives the user's first operation command, such as a water intake signal and target water intake parameters. The control module responds to the first operation command by starting the water purification module 10 and controlling the valve control 3 to be in a first state. This allows the heating module 2 to connect to the water outlet 6 via the valve control 3. At this time, the water dispenser operates in water dispensing mode. The water supplied by the water supply system 5 passes sequentially through the water purification module 10, the heat storage module 1, the heating module 2, and the valve control 3 before being output from the water outlet 6. During this process, the control module controls the operating state of the heating module 2 and the pumping component 4 according to the target water intake parameters, ensuring that the water output parameters at the water outlet 6 match the target water intake parameters. Because the water is preheated to a certain temperature before entering the heating module 2, the difference between the inlet temperature and the target temperature of the heating module 2 is reduced, allowing the heating module 2 to heat a larger flow of water to a higher temperature. Clearly, this design of the present invention can provide users with a large flow of high-temperature clean water in a customized manner, meeting the user's immediate need for hot water and ensuring drinking water health.

[0089] Meanwhile, the operation panel is used to receive the user's second operation command, which can be a power-on command or a heat storage command. The control module responds to the second operation command, and the control valve control 3 is in the second state, so that the water outlet of the heating module 2 is connected to the heat storage module 1 through the valve control 3, and the water purification module 10 is stopped. At this time, the water dispenser is running in heat storage mode, and the heat storage module 1, the heating module 2 and the valve control 3 are connected in sequence to form a circulating water circuit.

[0090] During the heat storage process of heat storage module 1, heating module 2 starts to operate. When the hot water output by heating module 2 flows through heat storage module 1, some of the heat of the hot water is transferred to the heat storage material in heat storage module 1. After the water temperature drops, it flows into heating module 2 for heating. This cycle continues until the water is heated to the target heating temperature.

[0091] The target heating temperature is greater than the phase change temperature of the heat storage material in the heat storage module 1, so as to ensure the effect of using hot water to store and charge the heat storage module 1.

[0092] It should be noted that, since the water dispenser in this embodiment is equipped with a water purification module 10, a heat storage module 1, and a heating module 2, it can efficiently provide a large flow of high-temperature clean hot water. This type of water dispenser can also be called an instant hot water dispenser.

[0093] In some embodiments, the water dispenser further includes an operation panel connected to a control module; the operation panel is used to receive user input of target water dispensing parameters, including target water temperature and target water dispensing volume.

[0094] Understandably, the control panel can be a touch screen. When the control panel receives the target water intake parameters, the control module controls the water dispenser to operate in the water dispensing mode. It controls the pumping flow rate of the pumping component 4 and the heating power of the heating module 2 with the target water intake parameters as the control target, so that the water temperature at the outlet 6 reaches the target water intake temperature and the water output of the outlet 6 meets the target water intake.

[0095] In some embodiments, such as Figure 1 As shown, the water dispenser also includes: a first temperature sensor 7 and a second temperature sensor 8, which are respectively connected to the control module; the first temperature sensor 7 is used to collect the outlet water temperature of the heating module 2, and the second temperature sensor 8 is used to collect the inlet water temperature of the heating module 2.

[0096] The target water intake parameters include the target water intake temperature. The control module is used to adjust the pumping flow rate of the pumping component 4 and the heating power of the heating module 2 according to the target water intake temperature, inlet water temperature and outlet water temperature, until the outlet water temperature reaches the target water intake temperature.

[0097] Specifically, the inlet water temperature of heating module 2 is set to T1, the outlet water temperature to T2, the outlet water flow rate of outlet 6 (equivalent to the pumping flow rate of pumping component 4) to m, the specific heat capacity of water to C, and the heating power of heating module 2 to P = mC(T2-T1). The heating power of heating module 2 is set to remain constant, and the difference between the outlet water temperature T2 and the inlet water temperature T1 is inversely correlated with the pumping flow rate of pumping component 4. Thus, the target water intake temperature Tt can be used as the control target, and the pumping flow rate of pumping component 4 and the heating power of heating module 2 can be adaptively adjusted so that the outlet water temperature T2 of heating module 2 can reach the target water intake temperature Tt as soon as possible, thus meeting the user's immediate drinking needs for hot water at the set temperature.

[0098] The heating module 2 includes a heating tube 21 and a jet assembly 22. By increasing the current of the heating tube 21, the heating temperature of the heating tube 21 can be increased, which means increasing the heating power of the heating module 2. This ensures that the outlet water temperature of the heating module 2 is T2 = Tt when the user takes water.

[0099] At the same time, the heating power of the heating module 2 is kept constant. The preheating of the heat storage module 1 is used to increase the inlet water temperature T1 of the heating module 2, which means that the outlet water flow rate m will be increased, thereby improving the user experience.

[0100] In some embodiments, such as Figure 1 As shown, the water dispenser also includes a third temperature sensor 9; the third temperature sensor 9 is embedded in the heat storage material and is used to collect the temperature of the heat storage material.

[0101] The third temperature sensor 9 is connected to the control module, which is connected to the water purification module 10, the pumping component 4, the heating module 2, and the valve control 3. When the temperature of the heat storage material collected by the third temperature sensor 9 is lower than the phase change temperature of the heat storage material (e.g., 70°C), the control module controls the valve control 3 to connect the water outlet and the water outlet 6 of the heating module 2, controls the water purification module 10 to stop operating, and controls the pumping component 4 and the heating module 2 to start operating, so that the water dispenser enters the heat storage mode and uses the hot water output by the heating module 2 to store heat in the heat storage module 1.

[0102] Of course, such as Figure 1 As shown, when the temperature of the heat storage material in the heat storage module 1 is lower than the phase change temperature of the heat storage material (e.g., 70°C), the control module can also control the heater to start operation, ensuring that the water dispenser, while operating in water dispensing mode, also uses the heater to store heat in the heat storage material in the heat storage module 1. In this case, the raw water supplied by the water supply system 5 passes through the water purification module 10, the heat storage module 1, the heating module 2, and the valve control 3 in sequence before being discharged from the water outlet 6.

[0103] In some embodiments, in order to accurately control the water output of the outlet 6, the water dispenser further includes a flow meter 200 and a timing module. The flow meter 200 and the timing module are respectively connected to the control module. The flow meter 200 is used to collect the pumping flow rate of the pumping component 4; the timing module is used to collect the pumping duration of the pumping component 4.

[0104] The target water intake parameters include the target water intake volume. The control module is used to calculate the water output of the outlet 6 based on the pumping flow rate and pumping time of the pumping component 4 when the outlet water temperature reaches the target water intake temperature; and to control the heating module 2 and the pumping component 4 to stop operating when the water output of the outlet 6 reaches the target water intake volume.

[0105] In some examples, the flow meter 200 can be located at the water inlet of the heat storage module 1 or the water inlet of the heating module 2. The flow meter 200 is also used to detect whether water flows through the heating module 2. The flow meter 200 is connected to the control module, and the control module is connected to the heating module 2. The control module is used to control the working state of the heating module 2 according to the flow signal fed back by the flow meter 200.

[0106] Understandably, the control module is used to start the heating module 2 when the flow signal fed back by the flow meter 200 is greater than the preset value, that is, only when water flows through the heating module 2, to prevent the heating module 2 from "dry burning" during operation, thus achieving safety protection for the heating module 2.

[0107] The preset value can be 180-220 mL / min, for example, the preset value is 180 mL / min, 200 mL / min or 220 mL / min.

[0108] In some embodiments, such as Figure 1 As shown, the water purification module 10 includes a water purification component 101 and a water distributor 102; the inlet end of the water purification component 101 is used to connect to the water supply system 5, and the outlet end of the water purification component 101 is connected to the inlet end of the heat storage module 1 through the water distributor 102; the water distributor 102 is also connected to the inlet end of the water purification component 101 to divert a portion of the water output from the water purification component 101 to the inlet end of the water purification component 101.

[0109] Understandably, the water purification component 101 includes a booster pump and a water purifier, which are arranged sequentially along the water flow direction; the water purifier uses the water treatment filter element shown in the above embodiment.

[0110] The water distributor 102 has a first port, a second port and a third port, which are connected to each other. The first port is connected to the water outlet of the water purification component 101, the second port is connected to the water inlet of the heat storage module 1, and the third port is connected to the water inlet of the water purification component 101.

[0111] Because the clean water output from the outlet of the water purification component 101 has a certain water pressure under the action of the booster pump, when the water flow rate (water pressure) of the water purification component 101 is too large, the water distributor 102 diverts a portion of the water flow output from the water purification component 101 to the water inlet of the water purification component 101. Thus, the water distributor 102 ensures that the water flow rate of the water purification component 101 and the water flow rate of the heat storage module 1 are kept in balance, preventing the pipeline between the water purification component 101 and the heat storage module 1 from experiencing "pressure buildup".

[0112] In some embodiments, such as Figure 1 As shown, the water purification module 10 also includes a valve control component, which is located between the water outlet of the water purification module 101 and the water inlet of the heat storage module 1. The valve control component is used to control the water outlet state of the water purification module 101.

[0113] Understandably, the valve control assembly includes a switching valve 103 and a zero-pressure valve 104, which are arranged sequentially along the water flow direction.

[0114] Since the water dispenser is equipped with a water dispensing button, an operation panel, and other human-machine interaction modules, when the human-machine interaction module receives a water dispensing signal, it controls the water purification module 10 to start operation. Specifically, the human-machine interaction module controls the booster pump corresponding to the water purification component 101 to start operation and controls the opening of the switch valve 103 corresponding to the valve control component, ensuring that the water purification module 10 can purify the raw water from the water supply system 5 and output clean water to the heat storage module 1. Among them, when the water purification module 10 supplies clean water to the heat storage module 1, the zero-pressure valve 104 is used to maintain the stability of the water outlet pressure of the water purification module 10.

[0115] Accordingly, when the human-machine interaction module receives a heat storage signal or a stop water intake signal, the human-machine interaction module controls the water purification module 10 to stop operating; specifically, the human-machine interaction module controls the booster pump corresponding to the water purification component 101 to stop operating, and controls the switch valve 103 corresponding to the valve control component to close, ensuring that the water purification module 10 no longer purifies the raw water from the water supply system 5, and cannot output water.

[0116] In some embodiments, such as Figure 1 As shown, an exhaust port 100 is provided on the pipeline between the water purification module 10 and the valve control 3.

[0117] Understandably, the vent 100 can be installed on the pipeline between the valve control 3 and the heat storage module 1. As the water temperature rises, the dissolved oxygen in the water will decrease. During the heat storage process of the heat storage module 1, the oxygen released from the water can be discharged through the vent 100 to prevent "pressure buildup" in the circulating water circuit composed of the heat storage module 1, the heating module 2, and the valve control 3.

[0118] In some embodiments, such as Figures 2 to 4 As shown, the heat storage module 1 includes a shell 11, a heat exchanger 12, and heat storage material; the shell 11 has a receiving cavity, the heat exchanger 12 is disposed in the receiving cavity, and the heat storage material is filled in the receiving cavity between the heat exchanger 12 and the shell 11; the water outlet of the heating module 2 is connected to the first end of the heat exchanger 12 and the water outlet 6 through a valve control 3; the first end of the heat exchanger 12 is connected to the water outlet of the water purification module 10, and the second end of the heat exchanger 12 is connected to the water inlet of the heating module 2.

[0119] Understandably, the shell 11 can be configured as a cube, and specifically made of heat-resistant plastic or stainless steel; the heat exchanger 12 can be in the form of stainless steel bent tube, tube-fin heat exchanger, plate heat exchanger, etc.; the heat storage material can be single-phase heat storage material such as water or cast aluminum, to provide heat by utilizing the sensible heat of the temperature difference between the heat storage material and the inlet water in the heat exchanger 12, or it can be phase change material such as hydrated salt heat storage material or paraffin wax, to provide heat by utilizing the heat energy generated during phase change.

[0120] In some examples, such as Figure 2 As shown, the heat exchanger 12 uses a coil 121, for example, the coil 121 is a stainless steel tube, and the coil 121 is arranged in a single layer inside the shell 11.

[0121] In some examples, such as Figure 3 As shown, the heat exchanger 12 includes a coil 121 and a fin assembly 122, with at least a portion of the coil 121 passing through the fin assembly 122. Optionally, the fin assembly 122 includes a plurality of fins arranged in a stacked manner, with the coil 121 passing between the stacked fins.

[0122] In some examples, such as Figure 4 As shown, the heat exchanger 12 includes a coil 121 and a fin assembly 122, which are stacked together. Optionally, the fin assembly 122 has upper and lower layers, with the coil 121 sandwiched between the upper and lower layers of the fin assembly 122. Each layer of the fin assembly 122 includes multiple fins stacked together.

[0123] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the heating module 2 includes a heating tube 21 and a jet assembly 22; the water inlet of the heating tube 21 is connected to the water outlet of the heat storage module, and the water outlet of the heating tube 21 can be selectively connected to the heat storage module and the water outlet through a valve control; the jet assembly 22 is disposed inside the heating tube 21, and the jet assembly 22 has a jet cavity 222 and a water inlet and a jet hole 2220 connected to the jet cavity 222, and the jet direction of the jet hole 2220 is towards the inner wall of the heating tube 21.

[0124] Understandably, the heating module 2 also includes: a water inlet and a water outlet; the water inlet is located at one end of the heating pipe 21 and is connected to the water outlet of the heat storage module; the water outlet is located at the other end of the heating pipe 21 and is connected to the water outlet; wherein, the jet assembly 22 is installed between the water inlet and the water outlet.

[0125] Meanwhile, the heating tube 21, as a functional element capable of heating fluids, can employ electric heating methods such as thick-film heating, quartz tube heating, nanofilm heating, cast aluminum heating, and stainless steel wire heating. Alternatively, it can use heat exchange methods such as steam heating or combustion heating to heat the fluid. The inner wall of the heating tube 21 serves as the heating wall surface. Through convective heat exchange between the jet fluid triggered by the jet assembly 22 and the heating wall surface, high heat exchange efficiency is ensured, improving the heating effect on the water.

[0126] In some embodiments, such as Figure 6 and Figure 7 As shown, the jet assembly 22 includes a central column 221 and multiple jet chambers 222; the multiple jet chambers 222 are arranged sequentially along the axial direction of the central column 221, and a water passage gap d is formed between the side wall of the jet chamber 222 and the inner wall of the heating tube 21; wherein, the water inlet is located on the side of the jet chamber 222 facing the heat storage module, and the jet hole 2220 is located on the side wall of the jet chamber 222.

[0127] Understandably, in actual operation, most of the fluid is ejected from the jet holes 2220 on the jet cavity 222, generating a jet fluid with a velocity perpendicular to the heated wall surface, which has a high heat exchange efficiency. Since there is a water passage gap d between the jet cavity 222 and the inner wall of the heating tube 21, a small amount of fluid flows out directly from the water passage gap d, forming a velocity component parallel to the heated wall surface. This part of the fluid merges with the jet fluid, guiding the jet fluid toward the water outlet of the heating module 2 while also enhancing the heat exchange efficiency with the heated wall surface.

[0128] After the fluid passes through the previous jet chamber 222 and exchanges heat with the heated wall, it enters the next jet chamber 222 along the mainstream direction and exchanges heat with the heated wall again. This process is repeated. After multiple jet heat exchanges, the temperature of the fluid continues to rise until it reaches the target temperature set for the process, and then flows out from the outlet.

[0129] In some embodiments, the jet cavity 222 is a cylindrical cavity, and the peripheral wall of the jet cavity 222 is provided with a water-blocking wing. The water-blocking wing extends along the circumference of the jet cavity 222, and the edge of the water-blocking wing is in contact with the inner wall of the heating pipe 21, or a water passage gap is formed between the edge of the water-blocking wing and the inner wall of the heating pipe 21, and the width of the water passage gap is smaller than the width of the water passage gap d.

[0130] The jet cavity 222 and the heating tube 21 are configured with compatible shapes. For example, the jet cavity 222 is a cylindrical cavity and the heating tube 21 is cylindrical. The jet cavity 222 and the heating tube 21 are coaxially arranged.

[0131] Optionally, the baffle can be located at one end of the jet cavity 222 facing the water inlet of the heating pipe 21. This design reduces the flow rate of the fluid passing through the water gap d and increases the flow rate of the jet fluid ejected from the jet hole 2220, which is beneficial to enhancing the jet heat exchange effect. Of course, the baffle can also be located axially in the middle of the jet cavity 222.

[0132] In some embodiments, such as Figure 6 As shown, the distance L between any two adjacent jet cavities 222 along the length of the heating tube 21 is 2 to 12 mm, that is, the distance L is greater than or equal to 2 mm and less than or equal to 12 mm; optionally, the distance L is 4 to 10 mm, that is, the distance L is greater than or equal to 4 mm and less than or equal to 10 mm.

[0133] In some embodiments, the heating module 2 further includes a water inlet connector 23 and a water outlet connector 24. The water inlet connector 23 is disposed at the water inlet end of the heating tube 21, and the water outlet connector 24 is disposed at the water outlet end of the heating tube 21.

[0134] In some examples, such as Figure 6 and Figure 7As shown, the water inlet connector 23 can guide external fluid into the heating tube 21. The water inlet connector 23 may include: a water inlet body, which is provided with a water supply port and a water inlet chamber. The water supply port is connected to the interior of the heating tube 21 through the water inlet chamber.

[0135] Optionally, the water inlet body can be made of metal material, such as stainless steel. The first end of the water inlet body is provided with a water supply port, which is connected to the water inlet chamber. The second end of the water inlet body is connected to the heating pipe 21.

[0136] In some examples, such as Figure 6 and Figure 7 As shown, the water outlet connector 24 can guide the fluid in the heating tube 21 to the outside. The water outlet connector 24 may include: a water outlet body, which is provided with a water inlet and a water outlet chamber. The water inlet is connected to the heating tube 21 through the water outlet chamber.

[0137] Similarly, the water outlet body can be made of metal material, such as stainless steel. The first end of the water outlet body is provided with a water inlet that is connected to the water outlet chamber. The second end of the water outlet body can be connected to the heating tube 21, and the water outlet chamber is connected to the heating tube 21.

[0138] In some embodiments, such as Figure 6 and Figure 7 As shown, the heating module 2 also includes a first sealing element 26 and a second sealing element 29. The water inlet connector 23 is sealed to the water inlet end of the heating tube 21 through the first sealing element 26, and the water outlet connector 24 is connected to the water outlet end of the heating tube 21 through the second sealing element 29.

[0139] It should be noted that the first sealing element 26 is sleeved on the end of the water inlet body facing the heating pipe 21, and the first sealing element 26 can form a seal between the water inlet body and the heating pipe 21.

[0140] For example, the first seal 26 may be made of high-temperature resistant rubber material, the second end of the water inlet body may be partially inserted into the heating tube 21, the first seal 26 is sleeved on the second end of the water inlet body, and the first seal 26 is provided with a radially outwardly extending annular abutment flange on the side of the first seal 26 near the water supply port.

[0141] During installation, the first sealing element 26 can be partially inserted into the heating tube 21 along with the second end of the water inlet body. The first sealing element 26 can simultaneously abut against the second end of the water inlet body and the inner wall of the heating tube 21. At the same time, the annular abutment flange of the first sealing element 26 can also simultaneously abut against the ends of the water inlet body and the heating tube 21. After the water inlet body is fixed to the end of the heating tube 21, the first sealing element 26 can be used to achieve a seal between the water inlet body and the heating tube 21.

[0142] Furthermore, in order to improve the sealing effect, multiple annular sealing flanges can be provided on the outer periphery of the first sealing member 26. These multiple annular sealing flanges are spaced apart along the axial direction of the heating tube 21, and each of these multiple annular sealing flanges can abut against the inner wall of the heating tube 21.

[0143] Therefore, by providing multiple annular sealing flanges on the outer periphery of the first sealing member 26, the sealing effect between the heating tube 21 and the first sealing member 26 can be further improved. In addition, the second sealing member 29 is sleeved on the end of the water outlet body facing the heating tube 21, and the second sealing member 29 can form a seal between the water outlet body and the heating tube 21.

[0144] Similarly, the second seal 29 can be made of high-temperature resistant rubber material, and the second end of the water outlet body can be partially inserted into the heating tube 21. The second seal 29 is sleeved on the second end of the water outlet body, and the side of the second seal 29 near the water inlet is provided with a radially outwardly extending annular abutment flange.

[0145] During installation, the second seal 29 can be partially inserted into the heating tube 21 along with the second end of the water outlet body. The second seal 29 can simultaneously abut against the second end of the water outlet body and the inner wall of the heating tube 21. At the same time, the annular abutment flange of the second seal 29 can also simultaneously abut against the ends of the water outlet body and the heating tube 21. After the water outlet body is fixed to the end of the heating tube 21, the second seal 29 can be used to achieve a seal between the water outlet body and the heating tube 21.

[0146] Furthermore, in order to improve the sealing effect, multiple annular sealing flanges can be provided on the outer periphery of the second sealing member 29. These multiple annular sealing flanges are spaced apart along the axial direction of the heating tube 21, and each of these multiple annular sealing flanges can abut against the inner wall of the heating tube 21.

[0147] Therefore, by providing multiple annular sealing flanges on the outer periphery of the second seal 29, the sealing effect between the heating tube 21 and the second seal 29 can be further improved.

[0148] In some embodiments, such as Figure 6 As shown, the heating module 2 also includes an inlet water temperature sensor 25 and an outlet water temperature sensor 30. The inlet water temperature sensor 25 is disposed at the inlet water connector 23, and the outlet water temperature sensor 30 is disposed at the outlet water connector 24. The heating module 2 is configured to control the heating temperature of the heating tube 21 according to the inlet water temperature of the inlet water temperature sensor 25 and the outlet water temperature of the outlet water temperature sensor 30.

[0149] In some embodiments, such as Figure 6 and Figure 7As shown, the heating module 2 also includes a first positioning member 27 and a second positioning member 28. Both the first positioning member 27 and the second positioning member 28 include a positioning disk 271 and a plurality of flow holes 272 arranged around the center of the positioning disk 271. The positioning disk 271 of the first positioning member 27 is clamped between the water inlet connector 23 and the first end of the central column 221, and the positioning disk 271 of the second positioning member 28 is clamped between the water outlet connector 24 and the second end of the central column 221.

[0150] In this configuration, the positioning disk 271 of the first positioning member 27 and the first end of the central column 221 are connected by a protrusion and a groove for positioning, and the positioning disk 271 of the second positioning member 28 and the second end of the central column 221 are connected by a protrusion and a groove for positioning.

[0151] In some embodiments, the heating tube 21 includes a heating tube body and a heating element, the heating element being disposed on the heating tube body and configured to heat the heating tube body.

[0152] In some embodiments, at least some of the heating elements and the jet cavity 222 are arranged opposite to each other. Specifically, when multiple jet cavities 222 are provided, the heating elements have multiple heating regions formed on the heating tube body. The multiple heating regions and multiple jet cavities 222 are arranged opposite to each other along the radial direction of the heating tube. This design is beneficial to enhance the jet strengthening effect and minimize the heat loss of the heating elements.

[0153] In some embodiments, the coverage of the heating area of ​​the jet cavity 222 and the heating tube 21 along the axial direction of the heating tube is not less than K, and the value of K ranges from 85% to 95%, that is, K is greater than or equal to 85% and less than or equal to 95%. For example, K can specifically be 85%, 90% or 95%.

[0154] It should be noted that, in order to maximize heat exchange efficiency within the limited length of the heating tube 21, the coverage of the heating area of ​​the jet cavity 222 and the heating tube 21 along the axial direction is not less than 85% to 95%.

[0155] That is, the sum of the lengths of the multiple jet chambers 222 is 85% to 95% of the total length of the heating area on the heating tube 21. For example, the sum of the lengths of the four jet chambers 221 is 90% of the total length of the heating area on the heating tube 21.

[0156] In some embodiments, the heating element includes one of the following: a thick film resistance heater, a nano-electronic film heater, a stainless steel heater, or a gas heating device.

[0157] In one embodiment, when the heating element is an electric heating element, the heating tube body can be made of a metal material, such as stainless steel or cast aluminum. A thick-film resistance heater, a nano-electronic film heater, or a stainless steel heater is attached to the outside of the heating tube body. When it is necessary to heat the fluid inside the heating tube body, these heaters can be energized. These heaters then generate high temperatures, causing the heating tube body to heat up. When the fluid flows through the heating tube body, the fluid can be heated.

[0158] In one embodiment, when the heating element is a heat exchange assembly, the heating tube body can be made of a metal material, such as stainless steel, and a gas heating device is provided on the outside of the heating tube body. When it is necessary to heat the fluid inside the heating tube body, gas can be supplied to the gas heating device. After obtaining the gas, the gas heating device can ignite the gas to make it burn, thereby heating the heating tube body to raise its temperature. When the fluid flows in the heating tube body, the fluid can also be heated.

[0159] In some embodiments, a parallel branch is provided between the inlet and outlet of the heat storage module 1; the inlet of the heating module 2 is connected to the outlet of the heat storage module 1, and the outlet of the heating module 2 is connected to the outlet 6; wherein, a control valve is provided on the parallel branch, so that the parallel branch can be selectively turned on or off.

[0160] Understandably, users can control the opening and closing of the parallel branch according to actual needs, switching between high-temperature and low-temperature water output modes. In high-temperature water output mode, the parallel branch is closed, allowing the water supplied by the water supply system to pass through the purification module, the preheating module, and the heating module in sequence before being output from the outlet, ensuring efficient supply of high-temperature hot water at a large flow rate. In low-temperature water output mode, the parallel branch is open, allowing the water supplied by the water supply system to flow directly through the parallel branch to the heating module after purification by the water purification module, and then be output from the outlet after being heated by the heating module, ensuring that the outlet outputs hot water at a relatively low temperature.

[0161] In the second aspect, such as Figure 8 As shown, this embodiment of the invention also provides a control method for the water dispenser described above, comprising the following steps:

[0162] Step 810: Obtain the water intake signal and target water intake parameters;

[0163] Understandably, water dispensers can be equipped with an operation panel and a water dispensing button. Users input a water dispensing signal via the water dispensing button and input target water dispensing parameters via the operation panel; users can also input both the water dispensing signal and target water dispensing parameters simultaneously via the operation panel. Target water dispensing parameters include the target water temperature and the target water volume.

[0164] Step 820: Based on the water intake signal, control the water purification module to start operation and control the valve control to connect the heating module and the water outlet;

[0165] Understandably, when the control panel feeds back the received water intake signal to the control module, the control module controls the booster pump corresponding to the water purification component to start running, and controls the opening and closing of the switch valve corresponding to the valve control component, so as to control the water purification module to start running, and the water purification module to purify the raw water from the water supply system.

[0166] At the same time, the control module controls the valve to connect the heating module and the water outlet, ensuring that the raw water supplied by the water supply system can pass through the water purification module, heat storage module, heating module and valve control in sequence before being discharged from the water outlet.

[0167] Step 830: Control the working state of the heating module and pumping components according to the target water intake parameters so that the water output parameters at the outlet are adapted to the target water intake parameters.

[0168] Understandably, when the control panel feeds back the received target water intake parameters to the control module, the control module uses the target water intake parameters as the control target and controls the heating power of the heating module and the pumping flow rate of the pumping components to make the water output parameters at the outlet match the target water intake parameters. This design can provide users with a large flow of high-temperature clean water in a customized manner, meeting users' immediate drinking needs for hot water and ensuring drinking water health.

[0169] In some embodiments, such as Figure 9 As shown, the target water intake parameters include the target water intake temperature. This embodiment demonstrates controlling the operating state of the heating module and pumping components based on the target water intake parameters, including the following steps:

[0170] Step 910: Obtain the target water intake temperature and the inlet and outlet water temperatures of the heating module;

[0171] Understandably, the user sets the target water temperature through the control panel, collects the outlet water temperature of the heating module through the first temperature sensor, and collects the inlet water temperature of the heating module through the second temperature sensor.

[0172] Step 920: Adjust the pumping flow rate of the pumping component and the heating power of the heating module according to the target water intake temperature, inlet water temperature and outlet water temperature until the outlet water temperature reaches the target water intake temperature.

[0173] Understandably, the inlet water temperature of the heating module is set to T1, the outlet water temperature to T2, the outlet water flow rate (equivalent to the pumping flow rate of the pumping component) to m, the specific heat capacity of water to C, and the heating power of the heating module to P = mC(T2-T1). The heating power of the heating module is kept constant, and the difference between the outlet water temperature T2 and the inlet water temperature T1 is inversely correlated with the pumping flow rate of the pumping component. Therefore, the target water intake temperature Tt can be used as the control target, and the pumping flow rate of the pumping component and the heating power of the heating module can be adaptively adjusted so that the outlet water temperature T2 of the heating module reaches the target water intake temperature Tt as quickly as possible, meeting the user's immediate drinking needs for hot water at the set temperature.

[0174] In some embodiments, such as Figure 10 As shown, the target water intake parameters also include the target water intake volume. This embodiment demonstrates controlling the operating status of the heating module and pumping components based on the target water intake parameters, including the following steps:

[0175] Step 110: Determine that the outlet water temperature has reached the target water intake temperature, and obtain the target water intake volume, the pumping flow rate of the pumping component, and the pumping time.

[0176] Understandably, when the outlet water temperature of the heating module reaches the target water intake temperature, the target water intake can be set through the operation panel, the pumping flow rate of the pumping component can be collected through the flow meter, and the pumping duration of the pumping component can be collected through the timing module.

[0177] Step 120: Calculate the outflow rate of the outlet based on the pumping flow rate and pumping duration of the pumping component.

[0178] Understandably, given a fixed outlet area, the pumping flow rate of the pumping component is multiplied by the outlet area, and the total flow rate is calculated cumulatively based on the pumping time to obtain the outlet flow rate.

[0179] Step 130: Determine that the water output from the outlet has reached the target water intake, and control the heating module and pumping components to stop operating.

[0180] Understandably, when the water flow from the outlet reaches the target water intake, the water purification module, heating module, and pumping components can be controlled to stop operating. At this time, the water in the user's water intake container is clean hot water with the target water intake temperature and the target water intake volume.

[0181] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
