Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a water dispenser. Background Technology

[0002] Plain boiled water, also known as cooled boiled water or chilled boiled water, plays a vital role in regulating the body's physiological functions. Drinking a glass of warm boiled water on an empty stomach in the morning can dilute the blood, reduce blood viscosity, promote blood circulation, reduce the risk of blood clots, prevent cardiovascular and cerebrovascular diseases, and quench thirst and promote urination as the body loses water during sleep. It can also make the skin smooth and delicate. However, different people have different preferences for the temperature of cooled boiled water, which means that users must first boil the water and then wait for it to cool down, which takes a relatively long time.

[0003] To address this technical problem, the applicant designed a water dispenser, including a water supply system comprising: a water supply device; a heating device, with its inlet connected to the outlet; a controller electrically connected to the heating device to control the heating of the supplied water to a target temperature; a heat exchange device, with its hot fluid inlet connected to the outlet of the heating device and its hot fluid outlet connected to the outlet of the water supply system; and its cooling water inlet connected to the outlet of the water supply device and its cooling water outlet connected to the inlet of the heating device. The heated water is cooled to the target outlet temperature via the heat exchange device. However, while this water dispenser can output cooled boiled water at a suitable temperature, it has numerous internal components and a complex water system. These components typically require multiple screws for fixing, increasing the overall cost and significantly reducing the ease of disassembly, thus affecting assembly efficiency.

[0081] As can be seen from the above technical solution, the water dispenser in this embodiment is provided with a support 1, and the support 1 includes a base plate 11 and a vertical wall 12. The base plate 11 and the vertical wall 12 can not only provide installation positions for the components inside the water dispenser, but also reasonably divide the space inside the water dispenser, making the internal structure of the water dispenser more neat and orderly. The water circuit is at least partially integrated into the first water circuit module 20, which reduces the number of internal parts and simplifies the structure of the water dispenser. The first water circuit module 20 also has a certain load-bearing and support function, which helps to increase the storage space inside the water dispenser. When installing the water dispenser, the operator only needs to install the first water circuit module 20 on the base plate 11, install the heating module 3 and the heat exchange module 4 on the vertical wall 12, and then install the water pump 21 and the regulating valve 22 on the first water circuit module 20 to complete the assembly of the water dispenser.

After passing through the water pump 21, the regulating valve 22 is in a fully open state. Due to the water pressure, the water flows into the third water flow channel 2008. There is no flow in the fourth water flow channel 2009. Then the water flows into the heating module 3 and is heated to the boiling state and flows out from the water outlet of the water dispenser for the user to drink.

[0092] When the "cooled boiled water" setting is selected, water pump 21 is activated. Water pump 21 causes water from the purified water tank to flow into the second water flow channel 2007 through the first end of the second water flow channel 2007. After passing through water pump 21, the regulating valve 22 is not fully open. By adjusting the opening of the regulating valve 22, water flows through the third water flow channel 2008 and the fourth water flow channel 2009 at a certain ratio. Part of the water flows directly into the heating module through the third water flow channel 2008 for heating, while part of the water flows through the fourth water flow channel 2009 from the heat exchange inlet 2004 and the cooling water inlet 401 into the heat exchange module to cool the hot water. The cooled water, after being heated by heat exchange, flows into the fifth water flow channel 2010 through the cooling water outlet 402 and the heat exchange outlet 2005. After merging with the water in the third water flow channel 2008, it enters the heating module to be heated to boiling water. Then, it enters the heat exchange module 4 for cooling. After cooling, it flows out from the water dispenser's spout for the user to drink.

[0093] In a preferred embodiment, the water pump 21 is a self-priming pump. The heating module 3 is preferably, but not limited to, an electric heating wire, an infrared heater, or a PTC heating element.

[0094] In this embodiment, the first water circuit module 20 can be disposed on one side of the base plate 11. Preferably, the first water circuit module 20 is located on the lower side of the base plate 11, which allows the first water circuit module 20 to fit closely with the base plate 11, reducing the area occupied by the first water circuit module 20. It also allows the first water circuit module 20 to be plugged into the water circuit and water tank disposed on the bracket 1, which helps to shorten the length of the water circuit in the water dispenser and simplifies the water circuit installation process.

[0095] like Figure 5 As shown, a first engaging assembly is provided between the top surface of the first water channel module 20 and the bottom surface of the base plate 11. A first positioning protrusion 111 is provided on one of the top surface of the first water channel module 20 and the base plate 11, and a first positioning groove suitable for engaging with the positioning protrusion is provided on the other. A first fixing hole 112 and a second fixing hole are respectively formed on the first water channel module 20 and the base plate 11 for fasteners to pass through sequentially.

[0096] During the installation of the first water channel module 20 under the base plate 11, the first positioning protrusion and the first positioning recess cooperate to pre-position the first water channel module 20 and the base plate 11, and engage the first engaging component. This partially replaces fasteners in connecting the first water channel module 20 and the base plate 11. Finally, fasteners pass through the first fixing hole 112 and the second fixing hole to reliably connect the top surface of the first water channel module 20 and the base plate 11, making it completely fixed under the base plate 11. This solution uses positioning protrusions and positioning recesses, as well as the first engaging structure, to replace at least three fasteners, reducing the amount of screws used. This allows three or even two fasteners to fix the first water channel module 20 to the base plate 11, improving the assembly efficiency of the water dispenser and reducing its manufacturing cost. The fasteners are preferably, but not limited to, bolts or rivets. In this embodiment, preferably, a screw post is formed on the base plate 11, and the first fixing hole 112 is formed on the screw post. The screw post can make surface contact with the screw, thereby preventing the screw from tilting and further improving the reliability of the connection between the first water channel module 20 and the base plate 11.

[0097] like Figure 6 As shown, in this embodiment, a heat exchange module slot 126 suitable for accommodating the heat exchange module 4 is formed on the vertical wall 12. A second engaging component is provided between the vertical wall 12 and the heat exchange module 4. The heat exchange module slot 126 can limit the heat exchange module 4 in an accommodating manner, and the second engaging component can quickly assemble the heat exchange module 4 into the heat exchange module slot 126 in a snap-fit ​​manner, which can prevent the heat exchange module 4 from moving relative to the vertical wall 12.

[0098] In this embodiment, the water dispenser also includes a circuit board 8. The circuit board 8 is communicatively connected to the heating module 3, the water pump 21, and the regulating valve 22. The circuit board 8 is detachably connected to the vertical wall 12. Figure 7 As shown, a wiring groove 122 surrounding the heat exchange module slot 126 is formed on the vertical wall 12. A partial anti-detachment protrusion 123 is formed on the side of the vertical wall 12 near the heat exchange module 4, partially obscuring the wiring groove 122. Wiring holes 131 are provided on the wiring groove 122 at positions corresponding to the water pump 21 and the regulating valve 22. This allows the vertical wall 12 to not only provide installation positions for the internal structure of the water dispenser but also to be used for wiring. The wiring holes 131 on the wiring groove 122 at positions corresponding to the water pump 21 and the regulating valve 22 facilitate the passage of wires through the wiring holes 131 and their connection to the water pump 21 and the regulating valve 22. The wiring groove 122 ensures the neat and orderly wiring layout of the internal components, making it easy to distinguish the power lines or data transmission lines of each component, and also facilitates disassembly and assembly. Furthermore, the anti-detachment protrusion 123 in the wiring groove 122 can restrain the wires within the wiring groove 122, reducing the need for cable ties.

[0099] Preferably, in this embodiment, the water dispenser also includes a power adapter connected to the power cord of the water dispenser. The base plate 11 also has a power adapter mounting groove, with limiting steps and positioning ribs on the left and right sides of the groove walls. Slots are provided at positions corresponding to the two ends of the power adapter to prevent movement. Limiting ribs are also provided on the left and right sides of the mounting groove to make the installation of the power adapter more stable and less prone to shaking. To prevent the power adapter from falling off, screw posts are provided at the top of the mounting groove, allowing for reliable securing of the power adapter with screws and preventing vertical movement. For easy wiring and disassembly of the power cord, the base plate 11 also has a slot structure suitable for fixing the power cord.

[0100] In this embodiment, as Figure 8 , 9 As shown in Figure 10, the water dispenser also includes a second water circuit module 10 and a solenoid valve 2. The second water circuit module 10 is detachably connected to the vertical wall 12. The second water circuit module 10 is also detachably connected to the upper side of the heat exchange module 4. The second water circuit module 10 has a first inlet 101, a second inlet 102, a first outlet 103, a second outlet 104, a heat exchange outlet 105, a heat exchange inlet 106, a first channel 107 connecting the first inlet 101 and the first outlet 103, a second channel 108 connecting the second inlet 102 and the heat exchange outlet 105, and a third channel 109 connecting the heat exchange inlet 106 and the second outlet 104. The heat exchange module 4 is located between the first water circuit module 20 and the second water circuit module 10.

[0101] The solenoid valve 2 is detachably connected to the second water circuit module 10 and has an inlet end 201, a first outlet end 202, and a second outlet end 203. The first outlet end 202 is connected to the first inlet 101, and the second outlet end 203 is connected to the second inlet 102. The solenoid valve 2 has a first state in which the inlet end 201 is connected to the first outlet end 202 and a second state in which the inlet end 201 is connected to the second outlet end 203.

[0102] In this embodiment, the heating module 3 heats the water to boiling point, and the boiling water flows from the heating outlet of the heating module 3 into the inlet 201 of the solenoid valve 2. When the user needs to drink the boiling water, the solenoid valve 2 is switched to the first state, and the boiling water flows from the first outlet 202 of the solenoid valve 2 into the first inlet 101, and then flows out from the first outlet 103 along the first channel 107 for the user's use. When the user needs to use cooled boiled water, the solenoid valve 2 is switched to the second state, and the boiling water flows from the second outlet 203 of the solenoid valve 2 into the second inlet 102, and then flows from the heat exchange outlet 105 along the second channel 108 into the hot water channel of the heat exchange module 4. Cooling water enters the cooling water channel through the cooling water inlet 401 of the heat exchange module 4, and cools the boiling water in the hot water channel, cooling it into cooled boiled water or warm water, and then flows into the heat exchange inlet 106 through the hot water outlet 404, and flows out from the second outlet 104 along the third channel 109 for the user's use. Therefore, this water circuit component can meet the user's needs for both boiled and cooled boiled water. By integrating the first channel 107, the second channel 108, and the third channel 109 into the second water circuit module 10, complex water pipe connections are avoided, resulting in a high degree of integration. At the same time, it facilitates connection with the solenoid valve 2 and the heat exchange module 4, which can significantly reduce the overall size of the unit.

[0103] The detachable connection between the second water channel module 10 and the vertical wall 12 can be implemented by a snap-fit ​​assembly, bolts, or rivets. Preferably, in this embodiment, the second water channel module 10 and the vertical wall 12 are threaded together. Furthermore, since the heat exchange module 4 is connected to the second water channel module 10, the second water channel module 10 can enhance the connection strength between the heat exchange module 4 and the vertical wall 12.

[0104] In this embodiment, as Figure 10 As shown, a first adapter 405 is provided between the second water circuit module 10 and the heating module 3. In this embodiment, a second adapter 110 is provided between the heating module 3 and the solenoid valve 2. The solenoid valve 2 is located above the heating module 3. This allows the solenoid valve 2, the heating module 3, the second water circuit module 10, and the heat exchange module 4 to be integrated together. The solenoid valve 2, the second water circuit module 10, the heat exchange module 4, and the heating module 3 can be simultaneously fixed to the vertical wall 12 by the first bolt, greatly reducing the cumbersome assembly operation and improving the assembly efficiency.

[0105] The water dispenser can be configured to include a raw water inlet suitable for connection to a tap water pipe and a filter cartridge connected to the raw water inlet. The purified water outlet of the filter cartridge is connected to a purified water tank, suitable for filtering tap water and feeding the filtered purified water into the purified water tank. Alternatively, the water dispenser can be configured to include only a purified water tank suitable for holding purified water, allowing users to fill the tank and the dispenser to instantly prepare cooled boiled water at a suitable temperature.

[0106] In this embodiment, as Figure 11 and Figure 12 As shown, the water dispenser also includes a filter element. The filter element is detachably connected to the base plate 11. The filter element has a filter inlet, a clean water outlet, and a wastewater outlet. The filter inlet is adapted to be connected to the outlet of the raw water tank. The first water circuit module 20 also includes a fifth water flow channel 2010. The first end of the fifth water flow channel 2010 is connected to the clean water outlet of the filter element, and the second end of the fifth water flow channel 2010 is connected to the clean water tank. The wastewater outlet of the filter element is adapted to be connected to the wastewater inlet of the wastewater tank.

[0107] Users can put tap water or drinking water into the raw water tank. The filter cartridge can filter the water in the raw water tank and input the filtered clean water into the clean water tank, and input the filtered wastewater back into the raw water tank.

[0108] In this embodiment, an upwardly extending fixing cylinder 113 is formed on the base plate 11. The fixing cylinder 113 is located on one side of the vertical wall 12, and the filter element is adapted to be inserted into the fixing cylinder 113. The bottom of the fixing cylinder 113 can limit the filter element in the height direction.

[0109] The connection between the filter cartridge inlet and the raw water tank, the connection between the filter cartridge's purified water outlet and the first end of the fifth water flow channel 2010 of the purified water tank, and the connection between the filter cartridge's wastewater outlet and the raw water inlet of the raw water tank can be implemented via silicone tubing. Preferably, in this embodiment, the water dispenser further includes a third water path module 7, which is detachably connected to the filter cartridge. The third water path module 7 has a sixth water flow channel 701, a seventh water flow channel 702, and an eighth water flow channel 703. The first end of the sixth water flow channel 701 is connected to the raw water outlet of the raw water tank, and the second end of the sixth water flow channel 701 is adapted to connect to the filter cartridge inlet. The first end of the seventh water flow channel 702 is connected to the purified water outlet of the filter cartridge, and the second end of the seventh water flow channel 702 is connected to the first end of the fifth water flow channel 2010. The first end of the eighth water flow channel 703 is connected to the wastewater outlet, and the second end of the eighth water flow channel 703 is connected to the raw water inlet of the raw water tank.

[0110] Preferably, in this embodiment, a fifth fixing hole 1131 and a sixth fixing hole 704 are formed on the outer peripheral wall of the fixed cylinder 113 and the third water channel module 7, respectively, for fasteners to pass through sequentially. This allows the third water channel module 7 to be fixedly connected to the fixed cylinder 113, thereby making the connection between the filter element and the third water channel module 7 more reliable.

[0111] Preferably, in this embodiment, a filter cartridge interface is formed on the third water channel module 7. The second end of the sixth water flow channel 701 is connected to the filter cartridge interface, and the water dispenser further includes a first sealing structure suitable for sealing the gap between the filter cartridge interface and the filter cartridge inlet; and / or,

[0112] The third water circuit module 7 has a purified water interface, and the first end of the seventh water flow channel 702 is connected to the purified water interface. The water dispenser also includes a second sealing structure suitable for sealing the gap between the purified water interface and the purified water outlet of the filter element; and / or,

[0113] The third water circuit module 7 has a wastewater interface, and the first end of the eighth water flow channel 703 is connected to the wastewater interface. The water dispenser also includes a third sealing structure suitable for sealing the gap between the wastewater interface and the wastewater outlet of the filter element.

[0114] The first, second, and third sealing structures not only improve the sealing performance between the filter element and the third water circuit module 7, but also enhance the connection strength between the filter element and the third water circuit module 7, enabling the filter element and the third water circuit module 7 to form a whole. Through the bolt connection between the third water circuit module 7 and the fixed cylinder 113, the filter element and the third water circuit module 7 can be reliably fixed to the fixed cylinder 113 at the same time.

[0115] In this embodiment, as Figure 13-16 As shown, a ninth water flow channel is formed on the base plate 11. The first end of the ninth water flow channel is adapted to connect with the first end of the sixth water flow channel 701. The water dispenser also includes a first check valve 91. The first check valve 91 is located below the raw water tank and its first end is connected to the second end of the ninth water flow channel. The second end of the first check valve 91 is connected to the raw water outlet of the raw water tank. The first check valve 91 can be switched to the open state when the raw water tank is placed on the bracket 1, and switched to the closed state when the raw water tank is not placed on the bracket 1.

[0116] A tenth water flow channel is formed on the base plate 11. The second end of the tenth water flow channel is adapted to connect with the second end of the eighth water flow channel 703. The water dispenser also includes a second check valve 92. The second check valve 92 is located below the raw water tank and connected to the raw water inlet of the raw water tank. It can switch to the open state when the raw water tank is placed on the bracket 1, and switch to the closed state when the raw water tank is not placed on the bracket 1.

[0117] The ninth and tenth water flow channels are provided on the base plate 11, which allows the raw water tank to be inserted into the ninth and tenth water flow channels when it is placed on the base plate 11, thereby making it easier for users to pick up and put down the raw water tank and improving the user experience.

[0118] The first check valve 91 and the second check valve 92 can open the water path when the raw water tank is placed on the base plate 11, thereby allowing the water production process to proceed smoothly. They can also cut off the water path when the raw water tank is removed from the base plate 11, preventing leakage at the ninth and tenth water flow channels. A first engaging member 911 is formed on the outer wall of the first check valve 91. A first receiving cavity 114 is formed on the base plate 11, which is connected to the second end of the ninth water flow channel. The first receiving cavity 114 is adapted to accommodate the first check valve 91. A first guide groove 115 is formed inside the first receiving cavity 114, which spirally surrounds the cavity wall of the first receiving cavity 114. The first guide groove 115 allows the first engaging member 911 to pass through. A first engaging groove 116 is provided at the end of the first receiving cavity 114, which is adapted to engage with the first engaging member 911.

[0119] A second engaging member 921 is formed on the outer wall of the second check valve 92. A second receiving cavity 117 is formed on the bottom plate 11, which is connected to the second end of the tenth water flow channel. The second receiving cavity 117 is adapted to accommodate the second check valve 92. A second guide groove 118 is formed inside the second receiving cavity 117, which spirally surrounds the cavity wall of the second receiving cavity 117. The second guide groove 118 allows the second engaging member 921 to pass through. A second engaging groove 119 is provided at the end of the second receiving cavity 117, which is adapted to engage with the second engaging member.

[0120] In this embodiment, as Figure 17 and Figure 18 As shown, the water dispenser also includes a pressure-stabilizing pump 93 disposed between the sixth water flow channel 701 and the ninth water flow channel. A third receiving cavity 120 protrudes upward from the base plate 11. The third receiving cavity 120 and the fixed cylinder 113 are located on the same side of the vertical wall 12. The pressure-stabilizing pump 93 is adapted to be placed inside the third receiving cavity 120. A ninth fixing hole 130 and a tenth fixing hole, respectively, are formed on the cavity wall of the third receiving cavity 120 and the pump cover of the pressure-stabilizing pump 93, allowing fasteners to pass through sequentially. The pressure-stabilizing pump 93 drives water from the raw water tank into the filter cartridge inlet, without filtering it into purified water.

[0121] This allows the pressure-stabilizing pump 93 to be inserted into the third receiving cavity 120 from below the base plate 11. Fasteners passing through the ninth and tenth fixing holes reliably secure the pressure-stabilizing pump 93 within the third receiving cavity 120. Positioning the third receiving cavity 120 and the fixing cylinder 113 on the same side of the vertical wall 12 allows for a more organized and compact internal structure by optimizing the space within the water dispenser. Preferably, raised ribs are present at the top of the third receiving cavity 120 to enhance structural strength.

[0122] In this embodiment, a wiring hole 131 is formed on the base plate 11, which passes through the cavity wall at the bottom of the third receiving cavity 120. This allows wires connected to the pressure stabilizing pump to pass through and be restrained, making the wiring inside the water dispenser neater.

[0123] In this embodiment, as Figure 19 and 20 As shown, the water dispenser also includes a water level detection device 94 suitable for detecting the water level in the raw water tank. Preferably, the water level detection device 94 includes a proximity switch and a float disposed in the raw water tank. The base plate 11 has a receiving groove 132 suitable for accommodating the proximity switch. The receiving groove 132 is disposed between the fixed cylinder 113 and the third receiving cavity 120, and is located on the side of the fixed cylinder 113 and the third receiving cavity 120 facing the raw water tank. A hook is formed on the groove wall of the receiving groove 132. A guide slope 1321 and an abutment surface 1322 are formed on the hook. From top to bottom, the guide slope 1321 is inclined in a direction away from the raw water tank, and the abutment surface 1322 is connected to the lower end of the guide slope 1321, suitable for abutting against the upper wall of the proximity switch.

[0124] This allows the guide slope 1321 to elastically deform when the proximity switch is pressed into the receiving groove 132, simultaneously guiding the proximity switch. After the proximity switch is placed into the receiving groove 132, the abutment surface 1322 can abut against the upper wall of the proximity switch, thereby preventing the proximity switch from disengaging from the limiting groove. Preferably, the end of the hook extends 1mm downward as a draft pivot, with the lower end drafting downward at 3° and the upper end drafting upward at 1°. This slight slope design achieves an interference fit with the proximity switch, restricting the front and rear degrees of freedom during assembly. Simultaneously, due to the two draft sections in different directions, this structure also has a certain effect of restricting upward movement. The corresponding upper end pressing buckle with a 1° draft restricts the vertical degrees of freedom.

[0125] In this embodiment, as Figure 21 and 22 As shown, the water dispenser also includes a purified water tank connector 95 detachably connected to the bracket 1. The first end of the purified water tank connector 95 is connected to the first end of the fifth water flow channel 2010. The second end of the purified water tank connector 95 is adapted to connect to the purified water tank. The purified water tank connector 95 can both inject purified water from the fifth water flow channel 2010 into the purified water tank and allow water from the purified water tank to flow out into the first water flow channel 2006 under the action of the water pump 21.

[0126] In this embodiment, a support protrusion is preferably formed on the outer wall of the fixing cylinder 113. A second positioning protrusion 951 is formed on one of the support protrusion and the water tank connector 95. A second positioning groove 134 adapted to the second positioning protrusion 951 is formed on the other of the support protrusion and the water tank connector 95. An eleventh fixing hole 135 and a twelfth fixing hole 952 for fasteners to pass through are respectively formed on the support protrusion and the water tank connector 95. The support protrusion can both improve the structural strength of the fixing cylinder 113 and fix the water tank connector 95. Through the cooperation of the second positioning protrusion 951, the second positioning groove 134, and the fasteners, the number of fasteners can be reduced, the installation of the water tank connector 95 can be accelerated, and reliable fixation of the water tank connector 95 can be ensured.

[0127] In this embodiment, the water dispenser also includes a micro switch connected to the water tank connector 95 and the base plate 11, with a micro switch wiring groove formed on the supporting protrusion. The micro switch can be used to determine whether the water tank is in place, ensuring good contact between the water tank and the water tank connector 95. The micro switch wiring groove facilitates the routing of the micro switch wiring.

[0128] In this embodiment, a top cover is detachably provided on the top of the bracket 1. A first fixing groove 124 suitable for accommodating a first magnetic element is formed on the top of the bracket 1. A second magnetic element suitable for attracting the first magnetic element is fixedly provided on the top cover.

[0129] The water dispenser also includes a side door assembly detachably connected to one side of the bracket 1. A second fixing groove 125 suitable for fixing a third magnetic element is formed on one side of the bracket 1, and a fourth magnetic element suitable for attracting the third magnetic element is provided on the side door assembly.

[0130] The top cover and side door can conceal the bracket 1 and water tank inside the water dispenser, thus preventing dust accumulation and improving the dispenser's aesthetics. The first fixing slot 124 and the second fixing slot 125 are designed with a certain angle to achieve a slight interference fit between the magnet and the bracket 1, thereby completing the installation and fixation of the magnet.

[0131] In summary, the water dispenser of this embodiment overcomes the shortcomings of existing water dispensers with the function of preparing cooled boiled water, such as low installation efficiency, inconvenience in disassembly, high scrap rate, and difficulty in promotion and application. Its structure is relatively simple, easy to disassemble, has high installation efficiency, low scrap rate, and can prepare cooled boiled water at a suitable temperature, making it easy to promote and apply.

[0132] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
