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, the water flow rate 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 household power systems, the water flow rate of instant water dispensers at the high-temperature setting is generally low, especially in winter when the water temperature is low, resulting in longer water dispensing times for users.

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.

[0031] The following is combined with 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.

[0032] like Figure 1 As shown, an embodiment of the present invention provides a water dispenser, including: a heat storage module 1, a heating module 2, a pumping component 4, and a control module; The inlet of the heat storage module 1 is used to connect to the water supply system 5; 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 through 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 electrically connected to the heating module 2, the pumping component 4 and the valve control 3 respectively. The control module is used to acquire water intake signals and target water intake parameters. Based on the water intake signals, the control valve control 3 connects the heating module 2 and the water outlet 6. Based on the target water intake parameters, the control module 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.

[0033] Understandably, the water supply system 5 can be either a water tank or a water purification system, which can stably supply water to the inlet of the heat storage module 1.

[0034] 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 supply system 5 is connected to the heating module 2 through the heat exchange channel.

[0035] The outlet of the heating module 2 can be connected to the inlet of the heat exchange channel or the middle of the heat exchange channel 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 phase change material. After the phase change material is fully charged, its temperature rises and it can maintain the temperature in the heat exchange channel within a preset range for a certain period of time, thereby preheating the cold water passing through the heat exchange channel.

[0036] In practical applications, the outlet of the heating module 2 can be connected to the heat storage module 1 before the user takes water, or during the user's free time (when there is no water taking operation), so that hot water can be used to charge the heat storage module 1.

[0037] 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.

[0038] Pumping component 4 is a hot water pump with flow control function to control the flow rate of pumped water. When the water dispenser is in water dispensing mode, pumping component 4 controls the water supplied by water supply system 5 to pass through heat storage module 1 and heating module 2 in sequence, and then flow out from water outlet 6. Among them, pumping component 4 controls the flow rate of pumped water, heat storage module 1 ensures the preheating temperature of water, and heating module 2 further controls the heating power of water. These three work together to ensure the flow rate and temperature of water output from water outlet 6.

[0039] 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.

[0040] 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.

[0041] 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 by 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, it can first be used to preheat the raw water supplied by the water supply system, and then the heating module 2 can be used to heat the preheated water, ensuring that the water outlet 6 outputs a large flow of high-temperature hot water.

[0042] Furthermore, the valve control 3 has a first state and a second state; the control module is used to control the valve control 3 to switch between the first state and the 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.

[0043] 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.

[0044] The human-computer interaction 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 controlling valve control 3 in a first state, allowing heating module 2 to connect to water outlet 6 via valve control 3. At this time, the water dispenser operates in water dispensing mode. Water supplied by the water supply system 5 passes sequentially through heat storage module 1, heating module 2, and valve control 3 before being output from water outlet 6. During this process, the control module controls the operating states of heating module 2 and pumping component 4 according to the target water intake parameters, ensuring that the water output parameters at water outlet 6 match the target water intake parameters. Because the water is preheated to a certain temperature before entering heating module 2, the difference between the inlet temperature and the target temperature of heating module 2 is reduced, enabling 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 hot water in a customized manner, meeting users' immediate drinking needs for hot water and ensuring drinking water health.

[0045] Meanwhile, the control 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 controls the valve control 3 to be 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. 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 path.

[0046] 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.

[0047] 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.

[0048] It should be noted that, since the water dispenser in this embodiment is equipped with a heat storage module 1 and a heating module 2, it can efficiently provide a large flow of high-temperature hot water. This type of water dispenser can also be called an instant hot water dispenser.

[0049] 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, which include target water temperature and target water dispensing volume.

[0050] 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 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.

[0051] 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. 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.

[0052] 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 reaches the target water intake temperature Tt as soon as possible, thereby meeting the user's immediate drinking needs for hot water at the set temperature.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] The third temperature sensor 9 is connected to the control module, which is connected to 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, and controls the pumping component 4 and the heating module 2 to start running, 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.

[0057] 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 heat storage module 1, the heating module 2, and the valve control 3 in sequence before being discharged from the water outlet 6.

[0058] In some embodiments, in order to accurately control the water output of the outlet 6, the water dispenser further includes a flow meter and a timing module, which are respectively connected to the control module. The flow meter is used to collect the pumping flow rate of the pumping component 4, and the timing module is used to collect the pumping duration of the pumping component 4. 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.

[0059] In some examples, the flow meter 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 is also used to detect whether water flows through the heating module 2. The flow meter 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.

[0060] Understandably, the control module is used to start the heating module 2 when the flow signal fed back by the flow meter 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.

[0061] 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.

[0062] In some embodiments, the water dispenser further includes a first trigger, which is connected to a control module; the first trigger is used to receive a water dispensing command signal, and the control module is used to control the valve control 3 to be in a first state according to the information fed back by the first trigger.

[0063] Understandably, since the first trigger and the control module are electrically connected, and the control module and the valve control 3 are electrically connected, the control module can control the working state of the valve control 3 according to the trigger command fed back by the first trigger, so that the water dispenser enters the water dispensing mode.

[0064] Optionally, the first trigger can be a water dispensing button, which can be located on the control panel and is used to receive the user's pressing command.

[0065] Optionally, the first trigger can be a trigger switch, which is located on the water intake valve at the water outlet 6 and will be triggered when the user opens the water intake valve.

[0066] In some embodiments, the water dispenser further includes a second trigger, which is connected to the control module; the second trigger is used to receive a power-on command signal or a heat storage command signal, and the control module is used to control the valve control 3 to be in a second state according to the information fed back by the second trigger.

[0067] Understandably, since the second trigger and the control module are electrically connected, and the control module and the valve control 3 are electrically connected, the control module can control the working state of the valve control 3 according to the trigger command fed back by the second trigger, so that the water dispenser enters the heat storage mode.

[0068] Optionally, the second trigger can be a power switch, which can be located on the operation panel. When the user presses the power switch to power on the water dispenser, the control module can respond to the power-on command signal from the power switch and control the water dispenser to enter the heat storage mode.

[0069] Optionally, the second trigger can be a heat storage button, which can be located on the operation panel. When the user presses the heat storage button, the control module can respond to the heat storage command signal fed back by the heat storage button and control the water dispenser to enter the heat storage mode.

[0070] 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 a 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 fills the receiving cavity between the heat exchanger 12 and the shell 11; The outlet of the heating module 2 is connected to the first end of the heat exchanger 12 and the outlet 6 via the valve control 3. The first end of the heat exchanger 12 is connected to the water supply system 5, and the second end of the heat exchanger 12 is connected to the inlet of the heating module 2.

[0071] 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.

[0072] 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.

[0073] In some examples, such as Figure 3As 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.

[0074] 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.

[0075] In some embodiments, such as Figure 1 As shown, the heat storage module 1 also includes a heater for heating the heat storage material.

[0076] Understandably, the heater can be installed either inside the housing 11 of the heat storage module 1 or on the outer surface of the housing 11; the heater can be an electric heating element such as a heating wire, a heating tube, or a constant temperature PTC heater.

[0077] Thus, in addition to using the hot water output from the heating module 2 to store heat in the heat storage material of the heat storage module 1, this embodiment can also directly use a heater to heat the heat storage material to achieve heat storage.

[0078] In this embodiment, while the water dispenser is operating in water dispensing mode, a heater is used to heat the heat storage material, ensuring that the water dispenser can operate in water dispensing mode for a long time.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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-passing 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-passing gap is smaller than the width of the water-passing gap d.

[0086] 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.

[0087] 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.

[0088] 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 2~12mm, that is, the distance L is greater than or equal to 2mm and less than or equal to 12mm; optionally, the distance L is 4~10mm, that is, the distance L is greater than or equal to 4mm and less than or equal to 10mm.

[0089] 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.

[0090] In some examples, such as Figure 6 and Figure 7 As 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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 near the water supply port.

[0097] 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.

[0098] 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.

[0099] Therefore, by providing multiple annular sealing flanges on the outer periphery of the first sealing element 26, the sealing effect between the heating tube 21 and the first sealing element 26 can be further improved.

[0100] In addition, the second seal 29 is fitted on the end of the water outlet body facing the heating pipe 21, and the second seal 29 can form a seal between the water outlet body and the heating pipe 21.

[0101] 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 second seal 29 is provided with a radially outwardly extending annular abutment flange on the side near the water inlet.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] In some embodiments, such as Figure 6 and Figure 7 As 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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 is in the range of 85% to 95%, that is, K is greater than or equal to 85% and less than or equal to 95%, for example, K can be 85%, 90% or 95%.

[0111] 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%~95%.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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: Step 810: Obtain the water intake signal and target water intake parameters; 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.

[0117] Step 820: Based on the water intake signal, the control valve connects the heating module and the water outlet; Understandably, when the control panel sends the received water intake signal back to the control module, 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 heat storage module, the heating module and the valve in sequence before being discharged from the water outlet.

[0118] 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.

[0119] 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 hot water in a customized manner, meet users' immediate drinking needs for hot water, and ensure drinking water health.

[0120] 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: Step 910: Obtain the target water intake temperature and the inlet and outlet water temperatures of the heating module; 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.

[0121] 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.

[0122] 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.

[0123] 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: 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. 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.

[0124] Step 120: Calculate the outflow rate of the outlet based on the pumping flow rate and pumping duration of the pumping component. 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.

[0125] 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.

[0126] Understandably, when the water flow from the outlet reaches the target water intake, the heating module and pumping components can be controlled to stop operating. At this time, the water in the user's water intake container is hot water with the target water intake temperature and the target water intake volume.

[0127] In some embodiments, the control method shown in this embodiment further includes the following steps: The temperature of the heat storage material in the heat storage module is obtained; when the temperature of the heat storage material is lower than the preset temperature, the water dispenser is controlled to operate in heat storage mode. At this time, the control valve connects the heating module and the heat storage module, and controls the heating module and the pump to start running. Alternatively, it can receive user input commands and control the water dispenser to operate in either water dispensing mode or heat storage mode based on those commands.

[0128] Understandably, when the water dispenser is powered on, it operates directly in heat storage mode, using the hot water output from the heating module to store heat in the heat storage module. After heating the heat storage material in the heat storage module to the set temperature, the water dispenser stops the heat storage mode and enters standby mode.

[0129] When a user performs a water dispensing operation, they input a first operation command into the control panel, and the control module controls the water dispenser to operate in water dispensing mode according to the first operation command.

[0130] If the user does not input the first operation command to the operation panel, but detects that the temperature of the heat storage material is lower than the preset temperature (e.g., 70°C) within a preset time (e.g., 10 seconds), the control module controls the water dispenser to work in heat storage mode. If the temperature of the heat storage material is higher than the preset temperature, the water dispenser remains in standby mode.

[0131] While the water dispenser is operating in heat storage mode, the user can click the water dispensing button or input the first operation command into the control panel, and the control module will control the water dispenser to switch from heat storage mode to water dispensing mode.

[0132] Of course, when the water dispenser is working in water dispensing mode, the user can input a second operation command into the control panel, and the control module can also control the water dispenser to switch from water dispensing mode to heat storage mode.

[0133] 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.
