Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, and in particular to a boiled water component and drinking water equipment. Background Technology

[0002] As people's living standards improve, consumers are paying more and more attention to drinking water health. Boiled water purifiers are becoming increasingly popular. As an upgraded version of regular water purifiers, they not only meet the needs of ordinary water purifiers but also rapidly cool purified water to a set temperature via a heat exchanger, unlike ordinary water purifiers which directly heat purified water to the set temperature. Compared to other types of water purifiers, boiled water purifiers better meet the Chinese people's need for cooled boiled water.

[0003] Currently, traditional boiled water purifiers mainly use high-power heating elements to heat the water flow instantaneously. However, this method has high power requirements and is only suitable for small flow rates, such as when making tea or coffee, where a small amount of boiled water needs to be obtained quickly. When users need to obtain a large amount of boiled water, the water dispensing will be slow. Utility Model Content

[0004] Therefore, it is necessary to provide a hot water component and drinking water device to address the problem of slow water dispensing when a large amount of hot water is used in a hot water purifier.

[0014] In one embodiment, the boiled water assembly includes a water circuit adapter, which is connected to the first switching valve, the outlet of the second flow channel, and the second switching valve respectively.

[0015] The second switching valve can controllably select one of the water storage component and the water storage component to be connected to the water circuit adapter, and the first switching valve can controllably select one of the water circuit adapter and the second flow channel to be connected to the heating component.

[0016] In one embodiment, the water circuit adapter includes a first water circuit, a second water circuit, and a third water circuit. The first water circuit, the second water circuit, and the third water circuit are all connected. The first water circuit is connected to the second flow channel, the second water circuit is connected to the first switching valve, and the third water circuit is connected to the second switching valve.

[0017] The water circuit adapter further includes a first temperature sensing element, which is disposed in the third water circuit.

[0018] In one embodiment, the boiled water assembly further includes a water replenishment switch valve, which is connected to the pure water pipeline and the water storage device respectively.

[0019] In one embodiment, a liquid level sensor is provided inside the water storage device. The liquid level sensor is communicatively connected to the water replenishment switch valve, and the water replenishment switch valve connects or disconnects the pure water pipeline and the water storage device according to the liquid level data of the liquid level sensor.

[0020] In one embodiment, the boiled water assembly further includes a room temperature switch valve, which is connected to the pure water pipeline and the water outlet respectively.

[0021] In one embodiment, the boiled water assembly further includes a flow regulating valve, which is connected to the pure water pipeline and the heat exchanger respectively, and can controllably regulate the water flow rate of the pure water pipeline entering the heat exchanger.

[0022] In one embodiment, the pure water structure includes a raw water pipeline and a filter element assembly. Both the raw water pipeline and the pure water pipeline are connected to the filter element assembly. The raw water input from the raw water pipeline to the filter element assembly is filtered by the filter element assembly and then output as pure water through the pure water pipeline.

[0023] In one embodiment, the filter assembly includes a first filter, a second filter, and a third filter. The first filter is connected to the raw water pipeline, and the first filter, the second filter, and the third filter are connected in sequence. The third filter is connected to the pure water pipeline.

[0024] The pure water structure also includes a concentrate pipeline, which is connected to the second filter element, and a concentrate switch valve is installed on the concentrate pipeline to control its own on / off state.

[0025] In one embodiment, the filter assembly includes a first connecting pipe and a return pipe. The first connecting pipe connects the first filter element and the second filter element, and the return pipe connects the pure water pipe and the first connecting pipe. The return pipe is provided with a return switch valve for controlling its own on / off state.

[0026] A drinking water device, comprising a boiling water component as described in any of the preceding claims.

[0027] In one embodiment, the drinking water device includes a housing with an indicator light that displays different colors depending on the operating status of the boiling water component.

[0028] In one embodiment, the drinking water device has a circulating heating mode and a boiled water dispensing mode;

[0029] When the drinking water equipment is in the circulating heating mode, the first switching valve connects the heating element and the second switching valve, and the second switching valve connects the first switching valve and the water storage element;

[0030] When the drinking water device is in the boiled water dispensing mode, the first switching valve connects the second flow channel and the heating element, and the second switching valve connects the second flow channel and the water outlet element.

[0031] The aforementioned boiled water assembly, on the one hand, after heat exchange, the temperature of the boiling water in the second flow channel drops, causing the boiling water to be cooled to a temperature suitable for direct drinking by the user. The boiled water flows from the outlet of the second flow channel into the water outlet, which can be a faucet or a pipe connected to an external faucet, thereby delivering the boiled water to the outside for the user to drink.

[0032] On the other hand, after passing through the first flow channel, the temperature of the pure water increases after exchanging heat with the boiling water. This results in the pure water flowing into the water storage unit at a higher temperature, which slows down the temperature drop in the water storage unit. Furthermore, the pure water in the water storage unit is already heated to near boiling temperature under the circulating heating mode. Thus, even if the user needs to take out a large amount of boiled water, the pure water can be heated to boiling quickly, ensuring the water dispensing speed and improving the user experience.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0054] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0059] See Figure 1 , Figure 2 and Figure 3This application provides a drinking water device, which can be a pipeline water dispenser, water dispenser, or other device used to output hot water or boiled water. The drinking water device includes a pure water structure 100, a heat exchanger 200, a water storage component 210, a heating component 220, a first switching valve 230, a second switching valve 240, and a water storage component 210. The pure water structure 100, heat exchanger 200, water storage component 210, heating component 220, first switching valve 230, and second switching valve 240 are interconnected and together form the boiled water component of the drinking water device. The boiled water component heats the pure water to boiling and then cools it to form boiled water, thereby meeting the user's need for boiled water.

[0060] The pure water structure 100 has a pure water pipeline 110 for outputting pure water. In actual use, the pure water structure 100 can be used to filter unfiltered water such as tap water to form pure water, or it can directly extract water from bottled water to form pure water. That is, pure water can be filtered tap water or bottled water or other purified water.

[0061] The heat exchange assembly includes a first flow channel and a second flow channel that can exchange heat with each other. The first and second flow channels are nested together so that the water flow in the first flow channel can exchange heat with the water flow in the second flow channel. The inlet of the first flow channel is connected to the pure water pipeline 110, and the outlet of the first flow channel is connected to the water storage device 210. That is, the pure water output from the pure water structure 100 through the pure water pipeline 110 passes through the first flow channel and enters the water storage device 210.

[0062] Furthermore, the water storage component 210 is connected to the heating component 220, the first switching valve 230 is connected to both the heating component 220 and the inlet of the second flow channel, the second switching valve 240 is connected to both the first switching valve 230, the outlet of the second flow channel and the water storage component 210, and the water outlet component 250 is connected to the second switching valve 240.

[0063] The first switching valve 230 can controllably select one of the second flow channel and the second switching valve 240 to connect to the heating element 220, the second switching valve 240 can controllably connect or disconnect the second flow channel and the water outlet 250, and the second switching valve 240 can controllably connect or disconnect the first switching valve 230 and the water storage element 210.

[0064] In actual use, the water dispenser has a circulating heating mode and a water dispensing mode. When the water dispenser is in the circulating heating mode, the first switching valve 230 connects to the heating element 220 and the second switching valve 240, and the second switching valve 240 connects to the first switching valve 230 and the water storage element 210. A schematic diagram of the water flow can be found here. Figure 4 , Figure 4The middle arrow indicates the direction of water flow. During the circulating heating mode of the drinking water equipment, the pure water structure 100 stops outputting pure water. The pure water in the water storage unit 210 first passes through the heating element 220, and the water temperature rises under the action of the heating element 220. After the temperature rises, the pure water flows through the first switching valve 230 to the second switching valve 240, and then flows back to the water storage unit 210 under the action of the second switching valve 240.

[0065] Thus, during the circulating heating mode of the water dispenser, the water storage unit 210 stops outputting pure water to itself due to the pure water structure 100. Therefore, the pure water in the storage unit 210 circulates between the heating element 220, the first switching valve 230, and the second switching valve 240, thereby continuously heating the pure water in the storage unit 210 until the water temperature reaches above 70°C, at which point the heating element 220 stops heating. The storage unit 210 is equipped with an insulation element, either externally or internally, which can insulate foam, etc., to maintain the temperature of the pure water inside the storage unit 210, facilitating subsequent water dispensing by the user.

[0066] When the drinking water equipment is in the boiled water dispensing mode, the first switching valve 230 connects the second flow channel and the heating element 220, and the second switching valve 240 connects the second flow channel and the water outlet 250. A schematic diagram of the water flow in the boiled water dispensing mode can be found in [reference needed]. Figure 5 In the boiled water intake mode, the pure water inside the water storage unit 210 first passes through the heating unit 220. Since the pure water in the water storage unit 210 has been heated to above 70°C during the circulation heating mode, when the high-temperature pure water passes through the heating unit 220 again, it will be heated to boiling by the heating unit 220. After boiling, the pure water will enter the second flow channel through the first switching valve 230.

[0067] After boiling, the pure water enters the second flow channel, and at the same time, the pure water pipe 110 of the pure water structure 100 also begins to output pure water. The pure water output from the pure water pipe 110 enters the first flow channel. Since the temperature of the pure water output from the pure water pipe 110 is mostly room temperature, the temperature of the pure water in the first flow channel is relatively low. The low-temperature pure water in the first flow channel will exchange heat with the boiling water in the second flow channel.

[0068] In this way, on the one hand, the boiling water in the second channel drops in temperature after heat exchange, so that the boiling water is cooled to a temperature that can be directly supplied to users for drinking. The boiled water flows from the outlet of the second channel to the water outlet 250. The water outlet 250 can be a faucet or a pipe connected to an external faucet, thereby delivering the boiled water to the outside for users to drink.

[0069] On the other hand, after passing through the first flow channel, the temperature of the pure water increases after exchanging heat with the boiling water. This results in a higher temperature of the pure water flowing into the water storage unit 210 from the first flow channel, which in turn causes the water temperature in the water storage unit 210 to drop more slowly. Furthermore, the pure water in the water storage unit 210 has already been raised to a near-boiling temperature under the circulating heating mode. Thus, even if the user needs to take out a large amount of boiled water, it can be ensured that the pure water can be heated to boiling quickly, ensuring the water dispensing speed and improving the user experience.

[0070] In some embodiments of this application, the hot water assembly further includes a water circuit adapter 300, which is interconnected with a first switching valve 230, the outlet of the second flow channel, and a second switching valve 240. The second switching valve 240 can controllably select one of the water storage component 210 and the water circuit adapter 300 to be connected to the water circuit adapter 300, and the first switching valve 230 can controllably select one of the water circuit adapter 300 and the second flow channel to be connected to the heating component 220.

[0071] Specifically, when the drinking water equipment is in the circulating heating mode, the first switching valve 230 connects the heating element 220 and the water circuit adapter 300, and the second switching valve 240 connects the water circuit adapter 300 and the water storage unit 210. At this time, the pure water in the water storage unit 210 passes through the heating element 220, the first switching valve 230, the water circuit adapter 300, and the second switching valve 240 in sequence and returns to the water storage unit 210, achieving the circulating heating effect.

[0072] When the drinking water equipment is in the boiled water dispensing mode, the first switching valve 230 connects the heating element 220 and the second flow channel, and the second switching valve 240 connects the water circuit adapter 300 and the water outlet 250. At this time, the pure water from the water outlet 250 passes through the heating element 220, the second flow channel, the water circuit adapter 300, the second switching valve 240, and the water outlet 250 in sequence, thereby outputting boiled water.

[0073] Furthermore, the drinking water equipment also includes a boiling water dispensing mode. In the boiling water dispensing mode, the first connecting valve connects the heating element 220 and the water circuit adapter 300, and the second switching valve 240 connects the water circuit adapter 300 and the water outlet 250. At this time, the water in the storage unit 210 passes through the heating element 220 to the first switching valve 230, the water circuit adapter 300 and the second switching valve 240, and finally enters the water outlet 250, thereby directly outputting boiling water heated by the heating element 220 to the user.

[0074] In some embodiments, the water circuit adapter 300 includes a first water circuit, a second water circuit, and a third water circuit. The first water circuit, the second water circuit, and the third water circuit are all connected. The first water circuit is connected to the second flow channel, the second water circuit is connected to the first switching valve 230, and the third water circuit is connected to the second switching valve 240. That is, the water circuit adapter 300 is a three-way structure.

[0075] The water circuit adapter 300 also includes a first temperature sensor 310, which is located in the third water circuit. As mentioned above, when the water dispenser is in any of the following modes—circulating heating mode, boiled water dispensing mode, or boiling water dispensing mode—the water flow must pass through the third water circuit to enter the second switching valve 240. Therefore, the first temperature sensor 310 located in the third water circuit can detect the water temperature in each mode. In particular, in the boiled water dispensing mode and the boiling water dispensing mode, the water temperature passing through the first temperature sensor 310 is close to the water temperature output from the outlet 250, thus allowing the corresponding water temperature information to be displayed to the user.

[0076] In some specific embodiments, the drinking water device also includes a controller module and a display panel 411. The controller module is communicatively connected to the first temperature sensing element 310 and is used to receive data from the first temperature sensing element 310, convert the data into a corresponding signal and output it to the display panel 411. Finally, the display panel 411 displays the water temperature to inform the user of the current water temperature.

[0077] In some embodiments of this application, the boiled water assembly further includes a water replenishment valve 211, which is connected to both the pure water pipeline 110 and the water storage unit 210. In actual use, if a user consumes a large amount of boiling water or cooked water, the water level in the water storage unit 210 will drop, requiring replenishment. At this time, the water replenishment valve 211 can be opened to directly connect the pure water pipeline 110 to the water storage unit 210, thereby directly replenishing the water storage unit 210 through the pure water pipeline 110.

[0078] Furthermore, a liquid level sensor 212 is installed inside the water storage unit 210. The liquid level sensor 212 is communicatively connected to the water replenishment switch valve 211, and the water replenishment switch valve 211 connects or disconnects the pure water pipeline 110 and the water storage unit 210 based on the liquid level data from the liquid level sensor 212. Specifically, both the liquid level sensor 212 and the water replenishment switch valve 211 are communicatively connected to the control module 460. When the control module 460 detects that the value of the liquid level sensor 212 is lower than or equal to a preset value, the control module 460 controls the water replenishment switch valve 211 to open, thereby replenishing water to the water storage unit 210.

[0079] In some embodiments of this application, the boiled water assembly further includes a flow regulating valve 214, which is connected to the pure water pipeline 110 and the heat exchanger 200 respectively, and can controllably regulate the flow rate of water entering the heat exchanger 200 from the pure water pipeline 110. In actual use, the heat exchange between the water flow in the first channel and the water flow in the second channel varies depending on the flow rate flowing into the first channel of the heat exchanger 200. Specifically, the greater the flow rate into the first channel, the more heat the water in the first channel can absorb from the water in the second channel, resulting in a lower temperature drop in the boiling water in the second channel and a lower temperature of boiled water obtained by the user. Conversely, the smaller the flow rate in the first channel, the higher the temperature of boiled water obtained by the user.

[0080] Furthermore, a first flow meter 215 is provided between the flow regulating valve 214 and the heat exchanger 200 to detect the flow rate of water entering the first flow channel and feed the detection data back to the control module 460. The control module 460 controls the opening and closing degree of the flow regulating valve 214 based on the detected flow data and the user's required boiled water temperature, thereby controlling the flow rate of water entering the pure water pipeline 110 and entering the heat exchanger 200.

[0081] In actual use, since there is a certain water pressure of 0.2-0.8MPa when the pure water pipeline 110 is discharged, the flow rate regulating valve 214 can adjust the water flow entering the heat exchanger 200 simply by adjusting the opening and closing angle of its own valve plate driven by the motor of the flow rate regulating valve 214.

[0082] In some embodiments of this application, the boiled water assembly also includes a room temperature switch valve 213, which is connected to the pure water pipeline 110 and the water outlet 250 respectively. The room temperature switch valve 213 is communicatively connected to the control module 460. When a user wants to drink room temperature water, he / she can open the room temperature switch valve 213 to allow pure water to be directly input into the water outlet 250, thereby outputting room temperature pure water for the user to drink or use.

[0083] Furthermore, the water outlet component 250 can be a main water outlet pipe installed on the outer casing 400. The water outlet component 250 can also include a pure water outlet pipe 405 and a hot water outlet pipe 406 respectively. The pure water outlet pipe 405 is directly connected to the pure water pipeline 110, while the hot water outlet pipe 406 is connected to the second switch valve.

[0084] In some embodiments of this application, in order to enable the pure water in the water storage unit 210 to be input to the heating unit 220, the hot water assembly also includes a water pump 260. The water pump 260 is connected to the heating unit 220 and the water storage unit 210 respectively, so as to draw pure water in the water storage unit 210 into the heating unit 220. Furthermore, a second flow meter 216 is provided between the water pump 260 and the water storage unit 210, so as to detect the flow rate of the water entering the water pump 260 according to the second flow meter 216. The user can control the water pump 260 to output the required amount of water according to the data of the second flow meter 216.

[0085] In some embodiments of this application, the pure water structure 100 includes a raw water pipeline 120 and a filter element assembly 130. The raw water pipeline 120 is connected to the raw water inlet 402 on the outer casing 400 of the drinking water device, and both the raw water pipeline 120 and the pure water pipeline 110 are connected to the filter element assembly 130. The raw water input from the raw water pipeline 120 to the filter element assembly 130 is filtered by the filter element assembly 130 and then output as pure water through the pure water pipeline 110. The raw water can be tap water or bottled water, etc. After being filtered by the filter element assembly 130, it is boiled to form cooked water for users to drink, which can effectively improve water quality and is beneficial to improving drinking water health.

[0086] Specifically, the filter element assembly 130 includes a first filter element 131, a second filter element 132, and a third filter element 133. The first filter element 131 is connected to the raw water pipeline 120, and the first filter element 131, the second filter element 132, and the third filter element 133 are connected sequentially. The third filter element 133 is connected to the pure water pipeline 110. The pure water structure 100 also includes a concentrated water pipeline 140. One end of the concentrated water pipeline 140 is connected to the second filter element 132, and the other end is connected to the concentrated water outlet 404 on the drinking water equipment housing 400. A concentrated water on / off valve 141 is installed on the concentrated water pipeline 140 to control its own on / off state. Thus, after filtration by the first filter element 131 and the second filter element 132, the resulting concentrated water is discharged from the concentrated water pipeline 140 and the concentrated water outlet 404. The filtered water is then filtered again by the third filter element 133, thereby achieving the output of pure water.

[0087] The filter assembly 130 includes a first connecting pipe 150 and a return pipe 151. The first connecting pipe 150 connects the first filter element 131 and the second filter element 132, and the return pipe 151 connects the pure water pipe 110 and the first connecting pipe 150. A return switch valve 152 is installed on the return pipe 151 to control its own on / off state. Thus, when the water quality is poor, the return pipe 151 can be opened, allowing water filtered by the first filter element 131, the second filter element 132, and the third filter element 133 to re-enter the second filter element 132 and undergo repeated filtration through the second filter element 132 and the third filter element 133 until the water quality meets the requirements. A check valve 153 is also installed on the return pipe 151 to prevent water from the first connecting pipe 150 from flowing into the return pipe 151.

[0088] Furthermore, to detect water quality, a first water quality detection element 161, an inlet valve 163, a filter flow meter 164, and a pressure stabilizing pump 160 are sequentially installed along the water flow direction in the first connecting pipe 150. A second water quality detection element 162 is installed on the pipe connecting the second filter element 132 and the third filter element 133. The water quality is detected by the first water quality detection element 161 and the second water quality detection element 162. Both the first water quality detection element 161 and the second water quality detection element 162 are communicatively connected to the control module 460, and the control module 460 displays the data detected by the first water quality detection element 161 and the second water quality detection element 162 on the display panel 411 so that the user can intuitively understand the current water quality.

[0089] Optionally, the first filter element 131 is a pre-filter PAC filter element, the second filter element 132 is an RO membrane filter element, and the third filter element 133 is a post-activated carbon filter element. The pre-filter PAC filter element and the post-activated carbon filter element can be arranged in the same filter element housing 400 so that the pre-filter PAC filter element and the post-activated carbon filter element are combined to form a composite filter element 134 for easy installation.

[0090] In some embodiments of this application, see [reference] Figure 6 , Figure 7 and Figure 8 The water dispenser includes a housing 400, on which an indicator light 401 is installed. The indicator light 401 displays different colors according to the working status of the hot water component to remind the user of the working status of the water dispenser. Specifically, the user can determine the current working condition of the water dispenser by observing the color or flashing frequency of the indicator light 401.

[0091] Optionally, when indicator light 401 displays a gradient blue, the water dispenser is in normal operation, meaning it can produce and dispense water normally. When indicator light 401 displays a gradient yellow, the water dispenser is in standby mode. When indicator light 401 displays a gradient red, the water dispenser is in water production / replenishment or internal circulation heating mode; in this case, you need to wait 2-3 minutes before you can dispense boiled or cooked water. If indicator light 401 displays a gradient red and flashes, it indicates a malfunction in the entire unit; the type of malfunction needs to be determined based on the flashing frequency / number of flashes / flash duration. If indicator light 401 displays a gradient blue and flashes, it indicates that filter element 130 has reached the end of its lifespan and needs to be replaced.

[0092] In some embodiments of this application, the drinking water equipment further includes a bracket 410, and a control module 460, a water storage component 210, a pressure stabilizing pump 160, a display panel 411, an RO membrane filter element, a composite filter element 134, a power adapter 420, a flow regulating valve 214, a filter element water circuit board module 430, a heat exchanger module 440, and an internal circulation heating and reflux module 450 are all mounted on the bracket 410. The control module 460 is located at the top of the bracket 410, thereby achieving separation of strong and weak currents and separation of water and electricity, better meeting the electrical safety requirements of the entire machine and improving its overall safety performance.

[0093] Furthermore, in order to drain the residual water inside the water passage of the water storage component 210, the water storage component 210 is placed at the top and front of the bracket 410, such as... Figure 7 In order to prevent water leakage due to the failure of the seal of the water storage component 210, which could cause damage to the display panel 411 and prevent it from working properly or displaying, the display panel 411 and the water storage component 210 are placed side by side on the top of the bracket 410 and located at the front end of the bracket 410.

[0094] In some embodiments, see Figure 9 The heat exchange module includes a heat exchanger 200, a heating element 220, a water pump 260, a first flow meter 215, and a second flow meter 216. The heat exchange module integrates a water circuit board, which connects the heat exchanger 200, heating element 220, water pump 260, and water storage unit 210. Furthermore, both the inlet 402 and outlet of the heating element 220 are equipped with temperature sensing elements to monitor the water temperature entering and exiting the heating element 220 in real time, thereby better regulating the heating power of the drinking water equipment.

[0095] In some embodiments, the water storage component 210 is a stainless steel tank with a liquid level sensor 212 installed on the top. The liquid level sensor 212 can be a liquid level probe, which is installed by tightening a nut. A sealing gasket is provided at the contact position between the probe and the water storage component 210. The outside of the water storage component 210 is covered with heat-insulating foam. The upper right side of the water storage component 210 has a water inlet pipe and a vent pipe, which are respectively connected to the water inlet 402 and the vent 403 provided on the outer casing 400. The bottom of the water storage component 210 has a water outlet pipe, which is connected to the water circuit board in the heat exchange module.

[0096] In some embodiments, see 10 and Figure 11 The filter element water circuit board assembly includes an inlet switch valve 163, a normal temperature switch valve 213, a reflux switch valve 152, a water supply switch valve 211, a wastewater switch valve, and a check valve 153. Two filter element fixing brackets 431 are provided at the bottom of the filter element water circuit board assembly for connecting the filter element water circuit board structure to the composite filter element 134 and the RO membrane filter element, respectively. A water circuit board is also formed inside the internal circulation heating reflux template, and it has a first switching valve 230, a second switching valve 240, a water circuit adapter 300, and a first temperature sensing element 310. The first switching valve 230 and the second switching valve 240 are fixed together in series using two integrally injection-molded water circuit board openings. Optionally, any of the above-mentioned switching valves are solenoid valves.

[0097] The above-mentioned hot water system has at least the following advantages:

[0098] During the circulating heating mode of the water dispenser, the pure water structure 100 stops outputting pure water to the water storage unit 210. Therefore, the pure water in the water storage unit 210 circulates between the heating element 220, the first switching valve 230, and the second switching valve 240, thus continuously heating the pure water in the water storage unit 210 until the water temperature in the water storage unit 210 reaches above 70℃, at which point the heating element 220 stops heating. The water storage unit 210 is equipped with an insulation element, either externally or internally, which can insulate foam, etc., to maintain the temperature of the pure water inside the water storage unit 210, facilitating subsequent water dispensing operations by the user.

[0099] When the drinking water equipment is in the boiled water dispensing mode, the first switching valve 230 connects the second flow channel and the heating element 220, and the second switching valve 240 connects the second flow channel and the water outlet 250. A schematic diagram of the water flow in the boiled water dispensing mode can be found in [reference needed]. Figure 5In the boiled water intake mode, the pure water inside the water storage unit 210 first passes through the heating unit 220. Since the pure water in the water storage unit 210 has been heated to above 70°C during the circulation heating mode, when the high-temperature pure water passes through the heating unit 220 again, it will be heated to boiling by the heating unit 220. After boiling, the pure water will enter the second flow channel through the first switching valve 230.

[0100] After boiling, the pure water enters the second flow channel, and at the same time, the pure water pipe 110 of the pure water structure 100 also begins to output pure water. The pure water output from the pure water pipe 110 enters the first flow channel. Since the temperature of the pure water output from the pure water pipe 110 is mostly room temperature, the temperature of the pure water in the first flow channel is relatively low. The low-temperature pure water in the first flow channel will exchange heat with the boiling water in the second flow channel.

[0101] In this way, on the one hand, the boiling water in the second channel drops in temperature after heat exchange, so that the boiling water is cooled to a temperature that can be directly supplied to users for drinking. The boiled water flows from the outlet of the second channel to the water outlet 250. The water outlet 250 can be a faucet or a pipe connected to an external faucet, thereby delivering the boiled water to the outside for users to drink.

[0102] On the other hand, after passing through the first flow channel, the temperature of the pure water increases after exchanging heat with the boiling water. This results in a higher temperature of the pure water flowing into the water storage unit 210 from the first flow channel, which in turn causes the water temperature in the water storage unit 210 to drop more slowly. Furthermore, the pure water in the water storage unit 210 has already been raised to a near-boiling temperature under the circulating heating mode. Thus, even if the user needs to take out a large amount of boiled water, it can be ensured that the pure water can be heated to boiling quickly, ensuring the water dispensing speed and improving the user experience.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
