Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a water circuit board assembly and a water dispenser. Background Technology

[0002] Water dispensers with heating functions typically include a heating module, a temperature sensing module, a water circuit system, and a release structure. The heating module heats the water, and the heated water is output through the water circuit system and the release structure. However, because the heating module needs to adjust the heating power based on the detection results of the temperature sensing module, some water is taken away before the temperature reaches the user's required temperature before the temperature control is stable, resulting in substandard water temperature.

[0003] In related technologies, some water dispensers have a water circuit switching element installed downstream of the temperature sensing module in the heating module. The water circuit switching element can return water to the water tank of the water dispenser when the water temperature does not meet the standard. However, this results in a large number of pipes in the water dispenser, a complicated connection process, and a risk of water leakage. Utility Model Content

[0004] In view of this, the present invention provides a water circuit board assembly and a water dispenser to solve the problems in the related technology that the water dispenser has many pipes, a complicated connection process, and a risk of water leakage.

[0005] In a first aspect, this utility model provides a water channel board assembly, comprising: The first water circuit board is provided with a first inlet, a water inlet circuit and a first outlet connected in sequence. The first inlet is used to connect with the heating module of the water dispenser. The waterway switching element has its input terminal connected to the first outlet. The second water circuit board is provided with a second inlet, an outlet water circuit, a second outlet, a third inlet, a return water circuit, and a third outlet. The second inlet is connected to the first output terminal of the water circuit switching element, the outlet water circuit is connected between the second inlet and the second outlet, and the second outlet can be connected to the water outlet of the water dispenser. The third inlet is connected to the second output terminal of the water circuit switching element, the return water circuit is connected between the third inlet and the third outlet, and the third outlet can be connected to the water tank of the water dispenser. The water circuit switching element has a first state of connecting the inlet water circuit and the outlet water circuit, and a second state of connecting the inlet water circuit and the return water circuit.

[0006] Beneficial effects: In the first aspect of this utility model, during use, the first water circuit board can be connected to the input end of the water circuit switching element, and the second water circuit board can be connected to the first and second output ends of the water circuit switching element. When the water temperature reaches the standard, the water circuit switching element can be switched to the first state, thereby allowing the qualified water to flow out through the water outlet of the water dispenser; when the water temperature does not reach the standard, the water circuit switching element can be switched to the second state, so that the water with the unqualified temperature flows back into the water tank of the water dispenser and is reheated, thereby preventing the unqualified water from flowing into the user's water cup before the water temperature stabilizes, and realizing the function of zero cold water in the first cup.

[0007] Based on this, the water circuit board assembly of this application embodiment includes a first water circuit board and a second water circuit board that are separately arranged. The first outlet for connecting the input end of the water circuit switching element is provided on the first water circuit board, and the second inlet and the third inlet for connecting the first output end and the second output end of the water circuit switching element are provided on the second water circuit board. Thus, the first water circuit board and the second water circuit board can be connected to the water circuit switching element from different directions, avoiding the problem that the water circuit switching element is difficult to assemble onto a rigid water circuit board because the directions of the input end and the output end of the water circuit switching element are different. Furthermore, since the water circuit board assembly in this application integrates the water circuit into the first water circuit board and the second water circuit board, it avoids the problems of having many pipes inside the water dispenser, complicated connection process, and risk of water leakage caused by connecting the water circuit assembly inside the water dispenser through pipes.

[0008] In one alternative implementation, the first water channel plate and the second water channel plate are detachably connected in a specified direction, and the first outlet, the second inlet and the third inlet extend in the specified direction.

[0009] Beneficial effects: With this setup, the operator can simultaneously complete the docking operation of the water circuit switching element with the first outlet, the second inlet and the third inlet when the first water circuit board and the second water circuit board are plugged in, which can further simplify the assembly process of the water circuit board assembly.

[0010] Based on this, the connection between the first water circuit board and the second water circuit board can further enhance the connection strength between the water circuit switching element and the first and second water circuit boards, thereby improving the connection stability of the entire water circuit board assembly, making the water circuit connection within the water circuit board assembly of this application more reliable and reducing the risk of leakage.

[0011] In one alternative embodiment, the second water circuit board has a receiving groove on one side for connecting to the first water circuit board, the water circuit switching element is disposed in the receiving groove, and the first outlet extends at least partially into the receiving groove.

[0012] Beneficial effects: With this configuration, the receiving slot can be used to accommodate the water circuit switching element and limit the water circuit switching element when the first water circuit plate is connected to the second water circuit plate, and make the structure of the water circuit plate assembly more compact.

[0013] In one optional embodiment, one of the first water channel plate and the second water channel plate is provided with a buckle, and the other of the first water channel plate and the second water channel plate is provided with a slot, the buckle being able to engage with the slot in a specified direction; and / or, The first water circuit board has a first connection hole, the second water circuit board has a second connection hole, and the water circuit board assembly also includes fasteners that can pass through the first connection hole and the second connection hole.

[0014] Beneficial effects: This setup allows operators to quickly connect the first and second water circuit boards, simplifying the assembly process of the water circuit board components.

[0015] In one alternative implementation, the first water channel plate and the second water channel plate are connected by a guide structure.

[0016] Beneficial effects: The guiding structure can guide the first water circuit board and the second water circuit board before they cooperate with each other, thereby ensuring that the first water circuit board and the second water circuit board can be accurately connected, and that the water circuit switching element can be accurately connected to the first outlet, the second inlet and the third inlet.

[0017] In one alternative embodiment, the second water channel plate further includes: The fourth inlet is used to connect to the purified water outlet of the water dispenser's filter cartridge; The purified water circuit connects the fourth inlet and the return water circuit.

[0018] Beneficial effects: With this configuration, the purified water filtered by the filter cartridge can flow into the water tank of the water dispenser sequentially through the fourth inlet of the second water circuit board, the purified water path, and the return water path. Thus, the function of simultaneously inputting purified water filtered by the filter cartridge and warm water that has not reached the required temperature into the water tank can be achieved by using the same water path on the second water circuit board. This simplifies the structure of the water circuit board assembly and reduces the number of openings on the water tank.

[0019] In one alternative implementation, the second water channel plate further includes: The fifth inlet is used to connect to the water tank vent of the water dispenser; The fifth outlet is used to connect to the water outlet of the water dispenser; The exhaust pipe connects the fifth inlet and the fifth outlet.

[0020] Beneficial effects: With this design, when the water tank is refilled, the airflow inside the tank can pass through the exhaust port, the fifth outlet, and the sixth outlet in sequence, and finally be discharged through the water outlet of the water dispenser. In addition, when the water dispenser malfunctions and the water tank is continuously refilled, the overflowing water can flow out through the exhaust port, which can prevent the continuous refilling of the water tank in the event of a malfunction from causing the whole machine to leak and causing a safety accident.

[0021] Secondly, this application achieves venting through a complete venting path, preventing external dust and bacteria from entering the water tank through the vent.

[0022] In one alternative embodiment, the water channel board assembly further includes: The temperature sensing module is located in the water inlet circuit and is used to detect the water temperature in the water inlet circuit; The control module communicates with the temperature sensing module and the water circuit switching element, and can control the water circuit switching element to switch between the first state and the second state according to the water temperature detected by the temperature sensing module.

[0023] Beneficial effects: With this setting, the control module can control the water circuit switching element to switch to the first state when the temperature detected by the temperature sensing module reaches the temperature required by the user, and control the water circuit switching element to switch to the second state when the water temperature detected by the temperature sensing module does not reach the temperature required by the user.

[0024] Meanwhile, the control module can control the power of the heating module based on the detection results of the temperature sensing module. For example, when the water temperature detected by the temperature sensing module is higher than the temperature required by the user, the heating module can be controlled to reduce its power. When the water temperature detected by the temperature sensing module is lower than the temperature required by the user, the heating module can be controlled to increase its power. Thus, the water temperature can be accurately controlled with just one temperature sensing module to meet the user's water needs.

[0025] In one alternative embodiment, the first water channel plate further includes: The mounting slot is connected to the first water channel, and the temperature sensing module is located inside the mounting slot.

[0026] Beneficial effects: With this configuration, the temperature sensing module can be placed inside the mounting slot, which not only allows it to directly contact the first water circuit to ensure the accuracy of water circuit temperature detection, but also helps to improve the structural compactness of the first water circuit board. After the temperature sensing module is placed inside the mounting slot, it can also seal the mounting slot, thereby ensuring the water circuit's airtightness and reducing the risk of water leakage.

[0027] In one optional embodiment, the water inlet channel includes a first section, a second section, and a third section connected in sequence. The first section extends in a specified direction, and the water channel switching element is spaced apart from the first section along the thickness direction of the first water channel plate. The third section is located above the first section and extends in a specified direction. The second section is connected between the first section and the third section.

[0028] Beneficial effects: With this configuration, the outlet of the heating module can be connected to the first section. The first section and the water circuit switching element are spaced apart along the thickness direction of the first water circuit plate. This can minimize the area of ​​the first water circuit plate and shorten the length of the inlet water circuit while ensuring that the first section does not interfere with the water circuit switching element. The third section is located on the upper side of the first section and can be connected to the input end of the water circuit switching element.

[0029] In one optional embodiment, the input end of the water circuit switching element is provided with a first connector, which is plugged into a first outlet; the water circuit board assembly further includes a first sealing ring, which is sandwiched between the first connector and the first outlet; and / or, The first output terminal of the water circuit switching element is provided with a second connector, which is inserted into the second inlet. The water circuit board assembly also includes a second sealing ring, which is sandwiched between the second connector and the second inlet; and / or, The second output end of the water circuit switching element is provided with a third connector, which is plugged into the third inlet. The water circuit board assembly also includes a third sealing ring, which is sandwiched between the third connector and the third inlet.

[0030] Secondly, this utility model also provides a water dispenser, comprising: Heating module; The water circuit board assembly of the second aspect of this utility model has a first inlet that is connected to the heating module. The third outlet of the water circuit board assembly connects to the water tank.

[0031] Beneficial effects: The water dispenser of the second aspect of this utility model includes or uses the water circuit board assembly of the first aspect of this utility model, and therefore has its beneficial effects, namely, it can prevent water that has not reached the standard temperature from flowing into the user's water cup before the water temperature stabilizes, thus achieving the function of zero cold water in the first cup.

[0032] Based on this, the water circuit board assembly of the water dispenser in this application embodiment includes a first water circuit board and a second water circuit board that are separately arranged. The first outlet for connecting the input end of the water circuit switching element is located on the first water circuit board, and the second inlet and the third inlet for connecting the first output end and the second output end of the water circuit switching element are located on the second water circuit board. Thus, the first water circuit board and the second water circuit board can be connected to the water circuit switching element from different directions, avoiding the problem that the water circuit switching element is difficult to assemble onto a rigid water circuit board because the input end and the output end of the water circuit switching element are in different directions. Furthermore, since the water circuit board assembly of the water dispenser in this embodiment integrates the water circuit into the first water circuit board and the second water circuit board, it avoids the problems of having many pipes inside the water dispenser, complicated connection process, and risk of water leakage caused by connecting the water circuit assembly inside the water dispenser through pipes.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined with Figures 1 to 14 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a water circuit board assembly is provided, including a first water circuit board 1, a water circuit switching element 2, and a second water circuit board 3.

[0039] The first water circuit board 1 is provided with a first inlet 1011, a water inlet circuit 1012, and a first outlet 1013 connected in sequence. The first inlet 1011 is used to connect with the heating module 6 of the water dispenser. The input terminal 201 of the water circuit switching element 2 is connected to the first outlet 1013. The second water circuit board 3 is provided with a second inlet 3011, an outlet water circuit 3012, a second outlet 3013, a third inlet 3014, a return water circuit 3015, and a third outlet 3016. The second inlet 3011 is connected to the first output terminal 202 of the water circuit switching element 2, the outlet water circuit 3012 is connected between the second inlet 3011 and the second outlet 3013, and the second outlet 3013 can be connected to the water outlet of the water dispenser. The third inlet 3014 is connected to the second output terminal 203 of the water circuit switching element 2, the return water circuit 3015 is connected between the third inlet 3014 and the third outlet 3016, and the third outlet 3016 can be connected to the water tank 7 of the water dispenser. The water circuit switching element 2 has a first state of connecting the inlet water circuit 1012 and the outlet water circuit 3012, and a second state of connecting the inlet water circuit 1012 and the return water circuit 3015.

[0040] In the first aspect of this utility model, during use, the first water circuit board 1 can be connected to the input terminal 201 of the water circuit switching element 2, and the second water circuit board 3 can be connected to the first output terminal 202 and the second output terminal 203 of the water circuit switching element 2. When the water temperature meets the standard, the water circuit switching element 2 can be switched to the first state, thereby allowing the qualified water to flow out through the water outlet of the water dispenser. When the water temperature does not meet the standard, the water circuit switching element 2 can be switched to the second state, so that the water with the unqualified temperature flows back to the water tank 7 of the water dispenser and is reheated, thereby preventing the unqualified water from flowing into the user's water cup before the water temperature stabilizes, and realizing the function of zero cold water in the first cup.

[0041] Based on this, the water circuit board assembly of this application embodiment includes a first water circuit board 1 and a second water circuit board 3 that are separately arranged. The first outlet 1013 for connecting the input end 201 of the water circuit switching element 2 is provided on the first water circuit board 1, and the second inlet 3011 and the third inlet 3014 for connecting the first output end 202 and the second output end 203 of the water circuit switching element 2 are provided on the second water circuit board 3. Thus, the first water circuit board 1 and the second water circuit board 3 can be connected to the water circuit switching element 2 from different directions, avoiding the water circuit switching element 2 being difficult to assemble onto a rigid water circuit board due to the different directions of the input end 201 and the output end of the water circuit switching element 2. Furthermore, since the water circuit board assembly of this application integrates the water circuit on the first water circuit board 1 and the second water circuit board 3, it avoids the problems of having many pipes inside the water dispenser, complicated connection process, and risk of water leakage caused by connecting the water circuit assembly inside the water dispenser through pipes.

[0042] In one embodiment, such as Figure 1 As shown, the first water channel plate 1 and the second water channel plate 3 are detachably connected in a specified direction, and the first outlet 1013, the second inlet 3011 and the third inlet 3014 extend in a specified direction.

[0043] With this setup, the operator can simultaneously complete the docking operation between the water circuit switching element 2 and the first outlet 1013, the second inlet 3011, and the third inlet 3014 when the first water circuit board 1 and the second water circuit board 3 are plugged in, which can further simplify the assembly process of the water circuit board assembly.

[0044] Based on this, the connection between the first water circuit board 1 and the second water circuit board 3 can further enhance the connection strength between the water circuit switching element 2 and the first water circuit board 1 and the second water circuit board 3, thereby improving the connection stability of the entire water circuit board assembly, making the water circuit connection in the water circuit board assembly of this application more reliable and reducing the risk of water leakage.

[0045] Among them, the water circuit switching element 2 is preferably, but not limited to, a three-way valve.

[0046] In one embodiment, such as Figure 5 As shown, the second water circuit board 3 is provided with a receiving groove 1014 on one side for connecting the first water circuit board 1, and the water circuit switching element 2 is located in the receiving groove 1014.

[0047] With this configuration, the receiving slot 1014 can be used to receive the water circuit switching element 2 and limit the water circuit switching element 2 when the first water circuit plate 1 is connected to the second water circuit plate 3, and make the structure of the water circuit plate assembly more compact.

[0048] In one embodiment, the first outlet 1013 extends at least partially into the receiving tank 1014, which can more reliably confine the water circuit switching element 2 within the receiving tank 1014.

[0049] In one embodiment, a buckle 3017 is provided on one of the first water channel plate 1 and the second water channel plate 3, and a slot 1015 is provided on the other of the first water channel plate 1 and the second water channel plate 3. The buckle 3017 can engage with the slot 1015 in a specified direction.

[0050] This configuration allows operators to quickly connect the first water circuit board 1 and the second water circuit board 3, simplifying the assembly process of the water circuit board components.

[0051] The first water circuit board 1 is provided with a first connection hole 1018, the second water circuit board 3 is provided with a second connection hole 303, and the water circuit board assembly also includes a fastener that can pass through the first connection hole 1018 and the second connection hole 303.

[0052] With this setup, the operator can reliably connect the first water channel plate 1 and the second water channel plate 3 together using fasteners.

[0053] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the connection between the first water channel plate 1 and the second water channel plate 3 may also be selected as adhesive bonding or magnetic connection, etc.

[0054] In one embodiment, such as Figure 7 and Figure 9 As shown, the first water channel plate 1 and the second water channel plate 3 are connected by the guide structure 4.

[0055] The guide structure 4 guides the first water circuit board 1 and the second water circuit board 3 before they cooperate with each other, thereby ensuring that the first water circuit board 1 and the second water circuit board 3 can be accurately connected, and ensuring that the water circuit switching element 2 can be accurately connected to the first outlet 1013, the second inlet 3011 and the third inlet 3014.

[0056] In one embodiment, the guide structure 4 includes a guide post 401 disposed on one of the first water channel plate 1 and the second water channel plate 3, and a guide groove 402 disposed on the other of the first water channel plate 1 and the second water channel plate 3. The guide post 401 extends in a specified direction and can be inserted into the guide groove 402.

[0057] In one embodiment, the water dispenser is an under-sink water purifier. The under-sink water purifier has a larger water flow rate. In this embodiment, the water dispenser connects the water circuit board assembly into one unit through the buckle 3017, the slot 1015, the first connecting hole 1018, and the second connecting hole 303, which can effectively improve the impact resistance of the water circuit board assembly.

[0058] In one embodiment, such as Figure 10 As shown, the second water circuit plate 3 is also equipped with a fourth inlet 3018 and a purified water circuit 3019.

[0059] The fourth inlet 3018 is used to connect to the purified water outlet of the water dispenser's filter cartridge. The purified water path 3019 connects the fourth inlet 3018 and the return water path 3015.

[0060] With this configuration, the purified water filtered by the filter element can flow into the water tank 7 of the water dispenser through the fourth inlet 3018, the purified water path 3019, and the return water path 3015 of the second water circuit board 3 in sequence. Thus, the function of simultaneously inputting purified water filtered by the filter element and warm water that has not reached the required temperature into the water tank 7 can be achieved by using the same water path on the second water circuit board 3. This simplifies the structure of the water circuit board assembly and reduces the number of openings on the water tank 7.

[0061] In one embodiment, such as Figure 14As shown, the second water circuit plate 3 also includes a fifth inlet 30110, a fifth outlet 30111, and an exhaust pipe 30112.

[0062] The fifth inlet 30110 is used to connect to the vent 701 of the water tank 7 of the water dispenser. The fifth outlet 30111 is used to connect to the water outlet of the water dispenser. The vent pipe 30112 connects the fifth inlet 30110 and the fifth outlet 30111.

[0063] With this configuration, when the water tank 7 is replenished, the airflow inside the water tank 7 can pass through the exhaust port 701, the fifth outlet 30111, and the sixth outlet in sequence, and finally be discharged through the water outlet of the water dispenser. In addition, when the water dispenser malfunctions and the water tank 7 is continuously replenished, the overflowing water can flow out from the faucet exhaust hole through the exhaust port 701, which can prevent the continuous replenishment of the water tank 7 in the event of a malfunction from causing the whole machine to leak and causing a safety accident.

[0064] Secondly, this application achieves exhaust through a complete exhaust path, preventing external dust and bacteria from entering the water tank 7 through the exhaust port 701.

[0065] In one embodiment, the vent 701 is located at the top of the water tank 7, above the highest water inlet height in the water tank 7, to ensure that the air in the water tank 7 can be discharged normally when water is introduced.

[0066] In one embodiment, the fifth outlet 30111 is connected to the water outlet of the water dispenser via a water pipe.

[0067] In one embodiment, the water dispenser includes a faucet with a water outlet located on it.

[0068] In one embodiment, the faucet is a display faucet.

[0069] In one embodiment, the water circuit board assembly further includes a temperature sensing module 5 and a control module.

[0070] The temperature sensing module 5 is located in the water inlet channel 1012 and is used to detect the water temperature in the water inlet channel 1012. The control module is communicatively connected to the temperature sensing module 5 and the water channel switching element 2, and can control the water channel switching element 2 to switch between the first state and the second state according to the water temperature detected by the temperature sensing module 5.

[0071] With this configuration, the control module can control the water circuit switching element 2 to switch to the first state when the temperature detected by the temperature sensing module 5 reaches the temperature required by the user, and control the water circuit switching element 2 to switch to the second state when the water temperature detected by the temperature sensing module 5 does not reach the temperature required by the user.

[0072] Meanwhile, the control module can control the power of the heating module 6 based on the detection results of the temperature sensing module 5. For example, when the water temperature detected by the temperature sensing module 5 is higher than the temperature required by the user, the heating module 6 is controlled to reduce its power; when the water temperature detected by the temperature sensing module 5 is lower than the temperature required by the user, the heating module 6 is controlled to increase its power. Thus, the water temperature can be accurately controlled with just one temperature sensing module 5 to meet the user's water intake needs.

[0073] Secondly, the temperature sensing module 5 is connected to the water inlet channel 1012, and there is no stagnant water in the installation location, which can improve the reliability of water temperature detection.

[0074] The control module may include programmable logic control components (such as PLC or CPU), memory, and electronic components connected to the programmable logic control components, which are well known to those skilled in the art and will not be described in detail here.

[0075] In one embodiment, the water dispenser may be equipped with multiple water temperature settings. For example, in one optional embodiment, the water temperature stored in the water tank 7 is about 45°C. The water dispenser is equipped with five settings: room temperature, 45°C, 65°C, 85°C, and boiling water. When a user takes hot water, water is drawn from the water tank 7 to the heating module assembly for heating, which saves the problems of long heating time and low flow rate when taking hot water.

[0076] In one embodiment, such as Figure 1 As shown, the first water circuit board 1 is also provided with a mounting groove 1016. The mounting groove 1016 is connected to the first water circuit, and the temperature sensing module 5 is located in the mounting groove 1016.

[0077] With this configuration, the temperature sensing module 5 can be placed inside the mounting slot 1016, which not only allows it to directly contact the first water circuit to ensure the accuracy of water circuit temperature detection, but also helps to improve the structural compactness of the first water circuit board 1. Furthermore, the temperature sensing module 5 can seal the mounting slot 1016 after being placed inside it, thereby ensuring the water circuit's airtightness and reducing the risk of leakage.

[0078] In one embodiment, the water inlet channel 1012 includes a first segment, a second segment, and a third segment connected in sequence.

The first section and the water circuit switching element 2 are spaced apart along the thickness direction of the first water circuit plate 1. Under the premise of ensuring that the first section does not interfere with the water circuit switching element 2, the area of ​​the first water circuit plate 1 can be minimized as much as possible, and the length of the inlet water circuit 1012 can be shortened. The third section is located on the upper side of the first section and can be connected to the input end 201 of the water circuit switching element 2.

[0080] In one embodiment, the second segment is tilted.

[0081] In one embodiment, the input terminal 201 of the water circuit switching element 2 is provided with a first connector, which is inserted into the first outlet 1013. The water circuit board assembly also includes a first sealing ring, which is sandwiched between the first connector and the first outlet 1013.

[0082] The first sealing ring can seal the gap between the first connector and the first outlet 1013, further reducing the risk of water leakage between the input end 201 and the first inlet 1011 of the water circuit switching element 2, so as to make the water circuit connection in the water circuit board assembly more reliable.

[0083] The first output terminal 202 of the water circuit switching element 2 is provided with a second connector, which is inserted into the second inlet 3011. The water circuit board assembly also includes a second sealing ring, which is sandwiched between the second connector and the second inlet 3011.

[0084] The second sealing ring can seal the gap between the second connector and the second inlet 3011, further reducing the risk of water leakage between the first output end 202 and the second inlet 3011 of the water circuit switching element 2, so as to make the water circuit connection in the water circuit board assembly more reliable.

[0085] The second output terminal 203 of the water circuit switching element 2 is provided with a third connector, which is plugged into the third inlet 3014. The water circuit board assembly also includes a third sealing ring, which is sandwiched between the third connector and the third inlet 3014.

With this arrangement, the operator can connect the first water channel plate 1 and the second water channel plate 3 to the bracket structure while using fasteners to connect the first water channel plate 1 and the second water channel plate 3 through the first connection hole 1018 and the second connection hole 303.

[0095] In one embodiment, the water dispenser includes a self-priming pump, the outlet of the water tank 7 is connected to the self-priming pump, and the self-priming pump can drive the water in the water tank 7 to flow to the heating module 6.

[0096] In one embodiment, when the user is not drawing water, the water in water tank 7 is circulated and heated. Specifically, the water in water tank 7 flows back to water tank 7 via a self-priming pump, heating module 6, first water circuit board 1, temperature sensing module 5, water circuit switching element 2, and second water circuit module. The temperature detected by the temperature sensing module 5 at the water inlet of heating module 6 is the temperature of the water in water tank 7. When the user draws water, especially at very low temperatures, water from water tank 7 is supplied first. Only when water tank 7 is empty will the water be directly heated using the filter cartridge and supplied to the user.

[0097] In one embodiment, the water dispenser is an under-sink water purifier, but the water dispenser in this application embodiment is not limited to this. For example, in the most recent optional embodiments, the water dispenser can also be a countertop water purifier, etc.

[0098] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
