[0045] A water purifier is a device used to purify tap water or other water sources, removing impurities, harmful substances, and odors to provide safer drinking water. Water purifiers can be used in various settings such as under the sink and in offices.

[0046] In related technologies, tabletop water purifiers are mostly instant-heating machines that can provide hot and room-temperature water. They are equipped with a water tank to store water, and when the water in the tank is low, users can add water to the tank using other water-holding or diversion tools. However, such tabletop water purifiers can cause inconvenience for users.

[0047] To address the issue of inconvenience for users of tabletop water purifiers in related technologies, referring to... Figure 1 and Figure 2 One embodiment of this application provides a benchtop water chiller, including a housing 100, a middle frame assembly 200, a filter element assembly 400, a refrigeration assembly 500, and a water outlet assembly 600. One end of the bottom of the housing 100 is provided with a water inlet 110 for connecting to an external water pipe. The middle frame assembly 200 is disposed inside the housing 100 and divides the inner cavity of the housing 100 into a filter element area 120 and a refrigeration area 130. The filter element area 120 is located away from the water outlet of the middle frame assembly 200. On one side of the water inlet 110, the cooling zone 130 is located on the side of the filter element zone 120 near the water inlet 110; the filter element assembly 400 is disposed in the filter element zone 120 and is used to filter and purify the water source from the external water pipe to obtain clean water; the cooling assembly 500 is disposed in the cooling zone 130 and is connected to the filter element assembly 400. The cooling assembly 500 is used to cool the purified water to obtain cold water; the water outlet assembly 600 is connected to the cooling assembly 500 and is used to outlet water.

[0048] The housing 100 includes a sealing plate 140, a bottom shell 150, a top shell 160, a top plate 170, and peripheral side plates 180. The bottom shell 150 has an opening at one end away from the inlet 110. A raised edge 152 extends upward from the peripheral edge of the bottom shell 150, but the side of the bottom shell 150 with the opening does not have the raised edge 152. The inlet 110 is located through the side wall of the raised edge 152 at the end of the bottom shell 150 away from the opening. The sealing plate 140 is located on the side of the bottom shell 150 with the opening, and its cross-section is semi-circular. The open end of the sealing plate 140 is connected to the middle frame assembly 200. Two peripheral side plates 180 surround the periphery of the bottom shell 150 with the raised edge 152. The overall cross-section of the two peripheral side plates 180 after splicing is U-shaped. One end of the top shell 160 is located above the sealing plate 140, and the other end of the top shell 160 is located above the middle frame assembly 200. The cross-section of the end of the top shell 160 above the sealing plate 140 is semi-circular, and the cross-section of the end of the top shell 160 above the middle frame assembly 200 is U-shaped. The corner of the top shell 160 near the water inlet 110 is chamfered. The top plate 170 is placed on top of the top shell 160 to close the opening of the top shell 160.

[0049] The middle frame assembly 200 provides stable support for the filter element assembly 400 and the refrigeration assembly 500, and can divide the internal space of the housing 100 to improve the compactness of the overall structure of the chiller.

[0050] Specifically, the external water pipe is used to connect to the municipal water supply. After the water source enters the chiller from the inlet 110, it first flows into the filter element assembly 400 for filtration and purification to obtain potable clean water. Then, through the cooperation of the refrigeration assembly 500 and the water outlet assembly 600, cold water that can be drunk directly is obtained.

[0051] The benchtop water chiller in this embodiment can be directly connected to municipal water supply via an external water pipe, thus achieving uninterrupted water supply. This eliminates the need for users to manually add water during use, improving user convenience. Furthermore, after the water source is filtered and purified by the filter element assembly 400, it becomes directly drinkable clean water. This purified water can also be further purified into directly drinkable cold water through the cooperation of the cooling assembly 500 and the water outlet assembly 600, further enhancing user convenience. In addition, the space within the housing 100 is rationally allocated by the middle frame assembly 200, placing the filter element assembly 400 in the filter area 120 and the cooling assembly 500 in the cooling area 130. This improves the compactness of the chiller's structure, reducing its overall footprint and facilitating user transport and relocation.

[0052] Reference Figure 2 and Figure 3 In some embodiments, the middle frame assembly 200 includes a first support portion 210, a second support portion 220, and a receiving portion 230. The second support portion 220 is disposed above the first support portion 210 and encloses a receiving area 240, in which a cooling area 130 is located. The receiving portion 230 is disposed on the side of the second support portion 220 away from the water inlet 110 and is located within the filter element area 120. The first support portion 210 and the receiving portion 230, facing the inner bottom wall of the housing 100, enclose the inner sidewall of the bottom of the housing 100 to form a holding area 250.

[0053] The first support section 210 includes four support columns. The second support section 220 includes a base plate 222, an end plate 224, and two side plates 226. The base plate 222 is horizontally arranged. The top wall of the support column is fixedly connected to the bottom wall of the base plate 222 and the bottom wall of the support column is fixedly connected to the inner bottom wall of the bottom shell 150. The end plate 224 is located at the end of the base plate 222 near the filter element assembly 400, and the bottom of the end plate 224 extends toward the inner bottom of the shell 100. The end of the side plate 226 away from the water inlet 110 is vertically connected to the end plate 224. The end plate 224 and the side plate 226 are both perpendicular to the base plate 222, that is, arranged in the vertical direction. The end plate 224, the base plate 222, and the side plate 226 can be integrally formed, and the end plate 224 protrudes from the side plate 226. A reinforcing rib 2262 is also fixed on the outer wall of the side plate 226 in the vertical direction to improve the support strength of the middle frame assembly 200. The bottom plate 222, end plate 224, side plate 226 and the inner wall of the shell 100 located on the side of the inlet 110 enclose the receiving area 240.

[0054] The receiving part 230 has an L-shaped longitudinal section and includes a horizontal plate 232 and a vertical plate 234. The vertical plate 234 is connected to the end plate 224, and its cross-section is similar to the letter M. The horizontal plate 232 is fixedly connected to the side wall at the bottom of the vertical plate 234. The horizontal plate 232 is fixedly disposed on the side of the vertical plate 234 away from the cooling zone 130. The horizontal plate 232 has a circular cross-section. The upper surface of the horizontal plate 232 and the side wall of the vertical plate 234 away from the end plate 224 enclose the filter element area 120. The bottom wall of the horizontal plate 232, the bottom wall of the bottom plate 222, and the inner wall at the bottom of the housing 100 enclose the holding area 250, which is located above the receiving area 240. The filter element area 120 is located on the side of the holding area 250 away from the inlet 110, and the cooling area 130 is located on the side of the holding area 250 close to the filter element area 120.

[0055] In this embodiment, the first support part 210, the second support part 220 and the receiving part 230 cooperate to reasonably distribute the inner cavity of the housing 100, dividing it into a filter element area 120, a holding area 250 and a receiving area 240, so as to neatly place the corresponding water purifier components and inlet and outlet water pipes 430; in addition, it can also provide good support for the cooling component 500 and the filter element component 400.

[0056] Reference Figures 2 to 4 In some embodiments, a pipe outlet 2320 is provided through the receiving part 230, the bottom of the filter element assembly 400 is connected to the water inlet 110 through the water inlet pipe, and the bottom of the filter element assembly 400 is also connected to the cooling component 500 through the water outlet 430. The water inlet pipe and the water outlet pipe 430 are both installed in the pipe outlet 2320, and the water outlet ends of the water inlet pipe and the water outlet pipe 430 are both located in the holding area 250.

[0057] Specifically, the pipe outlet 2320 is installed through the horizontal plate 232. Through the pipe outlet 2320, it is convenient to connect the water inlet pipe between the filter element assembly 400 and the water inlet 110, and connect the water outlet pipe 430 between the filter element assembly 400 and the cooling assembly 500. At the same time, it helps to ensure the neatness of the water inlet pipe and the water outlet pipe 430 in the housing 100.

[0058] Reference Figures 2 to 4 In some embodiments, the filter element assembly 400 includes a mounting bracket 410 and a filter element module 420. The mounting bracket 410 is disposed on a horizontal plate 232; the filter element module 420 is disposed on the mounting bracket 410 via a mounting member. The filter element assembly 400 also includes a sealing plate 440, which surrounds the filter element module 420 and is connected to the sidewall of the end plate 224.

[0059] Specifically, the height of the lower surface of the horizontal plate 232 is not lower than the height of the upper surface of the base plate 222. Two limiting grooves are provided on the top wall of the horizontal plate 232 along the horizontal direction, and the end of the limiting groove away from the refrigeration component 500 passes through the side wall of the horizontal plate 232. The mounting bracket 410 is sleeved with the filter module 420. Four limiting posts are connected to the four corners of the bottom wall of the mounting bracket 410. Two limiting posts located on the same side of the length direction of the limiting groove are slidably connected to one of the limiting grooves, and the other two limiting posts are slidably connected to the other limiting groove. The limiting posts are fixed to the horizontal part by screws.

[0060] The bottom of the filter module 420 is also provided with a water inlet 422 and a water outlet 424. The water inlet 422 is connected to the water inlet pipe so as to collect water from the water inlet 110; the water outlet 424 is connected to the water outlet pipe 430 so as to deliver the purified water filtered by the filter module 420 to the refrigeration unit 500. The bottom end of the sealing plate 440 is connected to the side wall of the horizontal plate 232 away from the middle frame assembly 200 by screws. The filter area 120 is formed by the sealing plate 440 and the receiving part 230.

[0061] In this embodiment, the cooperation of the sealing plate 440, the receiving part 230 and the mounting bracket 410 helps to install the filter module 420 and helps to ensure the compactness of the overall structure.

[0062] Reference Figures 2 to 5In some embodiments, the refrigeration assembly 500 includes a cooling tank 510 and a cooling water pipe. The cooling tank 510 is located within the refrigeration zone 130. The cooling tank 510 includes a connected cooling inlet 514 and a cooling outlet 512. The cooling outlet 512 is connected to the water outlet assembly 600, and both the cooling inlet 514 and the cooling outlet 512 are located above the cooling tank 510. The inlet end of the cooling water pipe is connected to the water outlet pipe 430, and the outlet end of the cooling water pipe is connected to the cooling inlet 514.

[0063] Since there is a certain space between the upper surface of the cooling tank 510 and the top plate 170, the refrigeration inlet 514 and the refrigeration outlet 512 are both opened on the top wall of the cooling tank 510 in order to accommodate the water pipes connected to the refrigeration inlet 514 and the refrigeration outlet 512, thereby ensuring the compactness of the chiller structure.

[0064] Specifically, the purified water, after being filtered and purified by the filter module 420, enters the cooling inlet 514 of the cooling tank 510 through the water outlet pipe 430, and after being cooled by the cooling tank 510, flows from the cooling outlet 512 to the water outlet assembly 600 for the user to drink.

[0065] Reference Figure 2 and Figure 3 In some embodiments, the benchtop chiller also includes a normal temperature water pipe, the inlet end of which is connected to the outlet pipe 430, and the outlet end of which is connected to the outlet assembly 600. The outlet assembly 600 is also used to control the on / off state of the normal temperature water pipe. The inlet ends of both the chilled water pipe and the normal temperature water pipe are located within the holding area 250.

[0066] Specifically, the water outlet pipe 430 has two outlet ends, one connected to the chilled water pipe and the other connected to the ambient temperature water pipe. Placing both the inlet ends of the chilled water pipe and the ambient temperature water pipe within the holding area 250 helps ensure the overall structure's regularity and compactness.

[0067] In this embodiment, by setting two outlet ends on the water outlet pipe 430, the water flow is divided into two paths to enter the cooling component 500. Under the control of the water outlet component 600, cold water and room temperature water can be discharged separately, thereby better meeting the user's water needs.

[0068] Reference Figure 2 and Figure 3 In some embodiments, the second support 220 is provided with two through grooves 2260 in the vertical direction on the side walls on both sides of the cold tank 510. One through groove 2260 is used to accommodate the pipe for chilled water, and the other through groove 2260 is used to accommodate the pipe for room temperature water.

[0069] The side plate 226 has two vertical grooves 2260 on the side wall away from the cooling zone 130. Both ends of the grooves 2260 penetrate the side wall of the side plate 226. One groove 2260 is used to accommodate a cooling water pipe, and the other groove 2260 is used to accommodate a room temperature water pipe. The outlet ends of both the cooling water pipe and the room temperature water pipe are located above the side plate 226.

[0070] Specifically, the through groove 2260 serves to limit and guide the chilled water pipes and the ambient temperature water pipes, ensuring the regularity of their layout. In addition, by opening the through groove 2260 on the side wall of the side plate 226, the internal space of the housing 100 occupied by the chilled water pipes and the ambient temperature water pipes can be reduced, thereby helping to further improve the structural compactness of the chiller.

[0071] Reference Figure 3 , Figure 5 and Figure 6 In some embodiments, the benchtop chiller also includes a solenoid valve flow meter module 800 disposed in the holding area 250. Both the chilled water pipe and the ambient temperature water pipe are connected to the solenoid valve flow meter module 800, which is used to monitor the inlet flow rate of the chilled water pipe and the ambient temperature water pipe.

[0072] The water outlet pipe 430 includes a first water outlet pipe 431 and a second water outlet pipe 432. The first water outlet pipe 431 is connected to the bottom of the filter element assembly 400. The solenoid valve flow meter module 800 includes a support frame 810, a flow monitoring element 820, and a solenoid valve 830. The support frame 810 is located in the holding area 250 and is connected to the second support part 220. The flow monitoring element 820 is located on the support frame 810. The inlet end of the flow monitoring element 820 is connected to the first water outlet pipe 431, and the outlet end of the flow monitoring element 820 is connected to the inlet end of the second water outlet pipe 432. The flow monitoring element 820 is used to monitor the inlet flow rate of the chilled water pipe and the inlet flow rate of the ambient temperature water pipe. The solenoid valve 830 has one inlet and two outlets. The inlet of the solenoid valve 830 is connected to the outlet end of the second water outlet pipe 432, one outlet of the solenoid valve 830 is connected to the chilled water pipe, and the other outlet of the solenoid valve 830 is connected to the ambient temperature water pipe.

[0073] Specifically, when the user controls the solenoid valve 830 connected to the ambient temperature water pipe to close and the solenoid valve 830 connected to the chilled water pipe to open via the water outlet component 600, the benchtop chiller can supply chilled water; when the user controls the solenoid valve 830 connected to the ambient temperature water pipe to open and the solenoid valve 830 connected to the chilled water pipe to close via the water outlet component 600, the benchtop chiller can supply ambient temperature water. The flow monitoring component 820 can monitor the inlet flow rates of both the chilled water pipe and the ambient temperature water pipe in real time to avoid excessive or insufficient water pressure. The flow rate can also be adjusted according to usage needs to ensure a moderate water volume during filtration, preventing incomplete filtration due to excessively fast flow or inefficient filtration due to excessively slow flow, thus ensuring user convenience when drinking water. Furthermore, to improve the installation efficiency of the chiller, the solenoid valve flow meter module 800 in this embodiment can be pre-integrated as a complete functional module and then fixed inside the housing 100 with screws.

[0074] Reference Figures 1 to 3 In some embodiments, the water outlet assembly 600 includes a tee connector 610, an outlet pipe, and a control component 620. The first interface end of the tee connector 610 is connected to the refrigeration outlet 512, and the second interface end of the tee connector 610 is connected to the outlet end of the ambient temperature water pipe. The inlet end of the outlet pipe is connected to the third interface end of the tee connector 610. The control component 620 is disposed on the housing 100 and is connected to the solenoid valve flow meter module 800. The control component 620 is used to control the solenoid valve flow meter module 800 to perform on / off operations on the refrigeration water pipe and the ambient temperature water pipe.

[0075] Due to the limited internal space of the housing 100, the chiller also includes a bent pipe connector 650 connected to the water outlet pipe to accommodate the filter module 420 with its smooth curved sides, thus optimizing the water outlet path. Additionally, the water outlet assembly 600 includes a water outlet base 630 and a water receiving platform 640. The water outlet base 630 is connected to the outer wall of the top housing 160 and has a flow guide channel that connects to the outlet end of the water outlet pipe; the outlet of the flow guide channel is the drinking water outlet. The water receiving platform 640 is connected to the outer wall of the bottom of the sealing plate 140 and has a water receiving trough inside. A perforated water receiving plate is located above the water receiving trough to hold water cups and other water-receiving tools, and the trough can collect excess water.

[0076] Specifically, the tee connector 610 is located above the cooling zone 130. The control unit 620 includes a connected control circuit board and control buttons. The control circuit board is installed inside the water outlet seat 630 and is connected to the solenoid valve 830. The control buttons include a cold water button and a room temperature water button. When the user presses the cold water button, the first interface of the tee connector 610 is connected, and only cold water flows out of the outlet pipe. When the user presses the room temperature water button, the second interface of the tee connector 610 is connected, and only room temperature water flows out of the outlet pipe.

[0077] In this embodiment, the combination of the three-way connector 610, the water outlet pipe, the control component 620, and the solenoid valve 830 facilitates the output of cold water or room temperature water according to user needs, thereby ensuring a good user experience for the chiller.

[0078] Reference Figures 3 to 5 In some embodiments, a drain outlet 112 is provided through the bottom wall of the housing 100. The benchtop chiller also includes a drain pipe 518. One end of the drain pipe 518 is connected to the condensate drain outlet 519 of the chiller, and the other end of the drain pipe 518 is connected to the drain outlet 112. A sealing member 190 for opening and closing the drain outlet 112 is provided on the bottom wall of the housing 100.

[0079] Since the chilled water produced by the refrigeration component 500 may not be consumed in time, and may deteriorate if stored in the refrigeration component 500 for a long time, affecting the user's health, it is necessary to release the unused chilled water periodically. The solenoid valve flow meter module 800 also includes a connecting plate 840, which is fixedly connected to the support frame 810 on the side near the filter module 420. The drain pipe 518 is fixed to the support frame 810 via the connecting plate 840, thus helping to ensure stability during drainage.

[0080] Specifically, the sealing component 190 includes a flexible sealing plug, which can be made of medical-grade silicone. During the use of this chiller, the flexible sealing plug is used to seal the drain outlet 112. After the chiller has been used for a period of time, the user can move the entire unit to the water tank, remove the flexible sealing plug, and drain the chilled water that has not been consumed for a long time from the refrigeration unit 500.

[0081] In this embodiment, the cooperation of the drain pipe 518 and the sealing component 190 allows users to promptly drain the prepared cold water from the water chiller if it has not been consumed for a long time, thus ensuring the health and safety of the cold water consumed by the user.

[0082] Reference Figure 7 In some embodiments, the chiller further includes a flow limiting and pressure limiting component 900, the inlet end of which is connected to the water inlet 110, and the outlet end of which is connected to the water inlet pipe.

[0083] Specifically, because the water pressure in municipal water supply is unstable, excessive water pressure may damage the filter element. Therefore, a flow-limiting and pressure-limiting component 900 is installed. The flow-limiting and pressure-limiting component 900 is a flow-limiting and pressure-limiting valve.

[0084] Reference Figure 2 and Figure 7 In some embodiments, the benchtop chiller also includes a power supply assembly 300 and a heat dissipation assembly 700. The filter assembly 400, the cooling assembly 500, the water outlet assembly 600, and the heat dissipation assembly 700 are all connected to the power supply assembly 300. The power supply assembly 300 is used to supply power to the filter assembly 400, the cooling assembly 500, the water outlet assembly 600, and the heat dissipation assembly 700 to ensure the normal operation of the chiller.

[0085] The power supply assembly 300 is positioned on top of the mid-frame assembly 200, above the receiving area 240, and on the side of the cooling area 130 near the water inlet 110. The heat dissipation assembly 700 is positioned on the side of the mid-frame assembly 200 near the water inlet 110, i.e., on the side of the receiving area 240 near the water inlet 110. The heat dissipation assembly 700 is positioned opposite the cooling assembly 500 to assist the cooling assembly 500 in dissipating heat.

[0086] Specifically, the heat dissipation assembly 700 includes a bracket 710 and a cooling fan 720. The bracket 710 is disposed between the inner sidewalls of the two side plates 226, and the cooling fan 720 is fixed by the bracket 710 and is disposed opposite to the cooling tank 510. Several air duct baffles 182 are provided through the sidewall of the peripheral side plate 180 opposite to the cooling fan 720, and an air inlet 154 is provided through the bottom wall of the bottom shell 150 near the water inlet 110. A heat-conducting element is provided on the sidewall of the cooling tank 510 near the cooling fan 720. The heat-conducting element includes several heat-conducting fins arranged in a horizontal array and vertically connected to the sidewall of the cooling tank 510. An air inlet notch 2220 is provided through the end of the bottom plate 222 away from the end plate 224.

[0087] Since the refrigeration component 500 generates a certain amount of heat when it is working, in order to ensure the normal operation of the chiller, the cooling fan 720 draws the cold air from the bottom of the chiller into the housing 100 through the air inlet 154 into the refrigeration zone 130. With the cooperation of the heat-conducting component 516, the heat generated by the cooling tank 510 is discharged through the air duct baffle 182, thereby achieving heat dissipation of the cooling tank and helping to ensure the normal operation of the chiller.

[0088] The benchtop chiller described in this application can be directly connected to the municipal water supply without frequent refilling, thus improving user convenience; and its compact layout helps reduce the space occupied by the whole unit, making it easy for users to move or transport.
