[0034] Referring to Figures 1 - 9 , a refrigeration structure of a water purifier, including a body 1, in which a filter element assembly 2 for filtering tap water, a pure water tank 3 for storing pure water, a cold water tank 4 for providing chilled water, and a thermoelectric cooler 5 are installed. The thermoelectric cooler 5 is a well-known technology in the industry and is a standard component that refrigerates through electric energy. The thermoelectric cooler 5 can both refrigerate and heat, and determines whether to refrigerate or heat on the same thermoelectric cooler 5 by changing the polarity of the direct current. This effect is generated through the thermoelectric principle. The pure water outlet of the filter element assembly 2 is communicated with the pure water tank 3, the pure water tank 3 is communicated with the cold water tank 4, the first surface of the thermoelectric cooler 5 is closely attached to the outer wall of the cold water tank 4, the second surface of the thermoelectric cooler 5 is closely attached to the outer wall of the first heat dissipation pipe fitting 6, the waste water outlet of the filter element assembly 2 is communicated with the water inlet of the first heat dissipation pipe fitting 6, the water outlet of the first heat dissipation pipe fitting 6 is communicated with the water inlet of the second heat dissipation pipe fitting 7, a heat dissipation fan 8 is installed on the outer wall of the second heat dissipation pipe fitting 7, and a plurality of sequentially communicated water flow channels 400 are provided on the cold water tank 4, the first heat dissipation pipe fitting 6 and the second heat dissipation pipe fitting 7 to increase the heat exchange area and make the water always flow from one end to the other end.

[0035] The filter element assembly 2 can be a composite filter element with multiple filter elements connected as a whole, or can be composed of multiple independent filter elements connected. The filter element assembly 2 at least includes a pre-filter 200, a reverse osmosis membrane filter element 201, and a post-filter 202. The pre-filter 200 is used to remove chlorine and organic impurities, reduce or remove scale, and can also absorb the peculiar smell, color, and odor generated by organic compounds in water. The reverse osmosis membrane filter element 201 is used to remove substances such as bacteria, viruses, and spores in water. The post-filter 202 is used to further improve the taste and remove peculiar smell. According to needs, more filter elements can be added to improve water quality. The purified water produced by the last-stage filter element in the filter element assembly 2 will flow into the pure water tank 3, and then flow into the cold water tank 4. The cooling surfaces of multiple thermoelectric coolers 5 are closely attached to the outer wall of the cold water tank 4 to cool the purified water in the cold water tank 4. The cold water in the cold water tank 4 flows out from the water outlet faucet 9 of the water purifier through a water pipe for users to use. The first heat dissipation pipe 6 is closely attached to the heating surfaces of multiple thermoelectric coolers 5, and the heat will be conducted to the first heat dissipation pipe 6. The waste water generated by the reverse osmosis membrane filter element 201 in the filter element assembly 2 enters the first heat dissipation pipe 6 and then flows into the second heat dissipation pipe 7. The waste water will take away the heat during the flowing process, and the cooling fan 8 blows the heat out of the machine. And the waste water is the water filtered by the pre-filter 200 and will not or rarely produce scale. The structure of the present application is relatively simple, the production cost is relatively low, the volume is small, the occupied space is small, the refrigeration and heat dissipation effects are good, it is convenient to use, the waste water generated by the reverse osmosis membrane filter element 201 is recycled or reused twice, which is energy-saving and environmentally friendly and is not easy to produce scale in the heat dissipation pipes, and can improve the service life and heat dissipation performance of the product.

This detachable structure is convenient for mold opening production and maintenance; a plurality of mounting holes 403 are correspondingly opened on the inner walls of the hollow box body 401 and the cover bodies 402, and fasteners are placed in each mounting hole 403 to connect and fix the cover bodies 402 and the hollow box body 401. The plurality of mounting holes 403 are located inside to avoid or reduce the probability of water leakage; a plurality of partition plates 404 are sequentially installed in the hollow box body 401, and the plurality of partition plates 404 form a plurality of sequentially connected water flow channels 400 in the hollow box body 401. In this way, the temperature is gradually reduced, and the phenomenon of temperature mixing caused by injecting normal temperature water can be avoided. Its refrigeration effect is good and the speed is fast. The structure of the first heat dissipation pipe 6 is basically the same as that of the cold water tank 4.

[0037] In some embodiments, a cold water outlet pipe 405 is provided on the cold water tank 4, which can be connected to the water outlet faucet 9 for users to drink; a drain pipe 406 is provided at the bottom of the cold water tank 4. When not in use for a long time, the water in the cold water tank 4 can be emptied, which is clean and hygienic.

[0038] In some embodiments, the filter element assembly 2 includes a pre-filter element 200, a reverse osmosis filter element, and a post-filter element 202. It further includes a first three-way valve 10 and a second three-way valve 11, both of which can be electric valves, solenoid valves, etc. The first three-way valve 10 has one water outlet and two water inlets. The second three-way valve 11 has one water inlet and two water outlets. The water inlet of the pre-filter element 200 is connected to the water outlet of the first three-way valve 10. One of the water inlets of the first three-way valve 10 is connected to the incoming tap water pipe, and the other water inlet is communicated with one of the water outlets of the second three-way valve 11. The other water outlet of the second three-way valve 11 is used to discharge the waste water outside the water purifier. The waste water outlet of the reverse osmosis filter element is connected to the water inlet of the first heat dissipation pipe fitting 6 through a water pump 12. The second heat dissipation pipe fitting 7 is connected to one of the water inlets of the first three-way valve 10 through the second three-way valve 11. The heated waste water flowing out of the second heat dissipation pipe fitting 7 can be discharged outside the water purifier through one of the water outlets of the second three-way valve 11, or can flow into the pre-filter element 200 through the first three-way valve 10 for reuse because the water temperature of the waste water has been reduced after heat dissipation. During the circulation of the waste water, the heat generated by the thermoelectric cooler 5 will be carried away.

[0039] In some embodiments, a sealing ring 407 is installed between the hollow box body 401 and the cover body 402 to improve the sealing and leak-proof performance.

[0040] In some embodiments, both the thermoelectric cooler 5 and the first heat dissipation pipe fitting 6 are flat bodies, and their fitting degree is good, increasing the refrigeration and heat conduction areas. The thermoelectric cooler 5 is tightly fixed face to face with the hollow box body 401 and the first heat dissipation pipe fitting 6 to increase the contact surface. The hollow box body 401, the first heat dissipation pipe fitting 6, and the second heat dissipation pipe fitting 7 are made of copper or aluminum alloy, and their heat conduction and refrigeration effects are good.
