[0054] like Fig.11 As shown, the water purifier body 100 includes a raw water tank 102, a filter component 101, a boost pump 103 and a flushing solenoid valve 104. The boost pump 103 is connected between the raw water tank 102 and the filter component 101. The water outlet of the filter component 101 is connected to the clean water tank 200. The concentrated water outlet of the filter component 101 is connected to the raw water tank 102 through the flushing solenoid valve 104.

[0055] like Fig.11As shown, the filter component 101 includes a polypropylene activated carbon composite filter element 105, a reverse osmosis membrane filter element 106 and an activated carbon water purification composite filter element 107. The raw water in the raw water tank 102 is filtered in turn through the polypropylene activated carbon composite filter element 105, the reverse osmosis membrane filter element 106 and the activated carbon water purification composite filter element 107 under the action of the booster pump 103, and the filtered clean water is transported to the clean water tank 200.

[0056] like Figure 3 As shown, the clean water tank 200 and the ice water tank 300 are both arranged on the water purifier body 100 and the ice water tank 300 is arranged corresponding to the clean water tank 200 in the height direction.

[0057] The water purifier further includes a fixing frame 900 disposed on the water purifier body 100, a first pump 400, a first switching valve 500, a heating pipe 600, a second switching valve 700, and a second pump 800 are integrated and arranged inside the fixing frame 900, and a clean water tank 200 and an ice water tank 300 are radially arranged above the fixing frame 900. The water purifier is highly integrated, and has a compact structure, a small volume, and is easy to assemble.

[0058] Specifically, the first pump 400 is arranged below the clean water tank 200, the second pump 800 is located below the ice water tank 300, and the first pump 400 is arranged corresponding to the second pump 800 in the height direction.

In addition, the first switching valve 500 and the second switching valve 700 are located between the first pump 400 and the second pump 800.

[0059] like Fig.11 In the present embodiment, the water purifier includes a first water circuit, which includes a water supply circuit and a cooling circuit connected to each other, wherein the water purification tank 200, the first pump 400, and the first switching valve 500 constitute the water supply circuit, the ice water tank 300, the second pump 800, and the water outlet 705 constitute the cooling circuit, and the ice water tank 300 is connected to the second drain outlet 503 of the first switching valve 500. When the ice water tank 300 turns on the cooling function, the first water circuit can discharge ice water, and the ice water temperature is 6-12 degrees; when the ice water tank 300 does not turn on the cooling function, the first water circuit can discharge normal temperature water. Since people generally need ice water in the hot summer, the role of the ice water tank in other seasons is not so prominent, so when the ice water tank 300 does not turn on the ice water making state, the ice water tank 300 can also be used as a normal temperature water intake, which not only ensures that the water inside the ice water tank can flow when it is not used for a long time, but also increases the capacity of the water purification tank 200.

[0060] In addition, the refrigeration water circuit is composed only of the ice water tank 300, the second pump 800 and the water outlet 705. The ice water comes out of the ice water tank 300 and directly enters the water outlet 705 through the second pump 800. In this state, the ice water will not pass through other water circuits of the entire machine. The path from the ice water to the water outlet 705 is simple, avoiding energy loss and the influence of other components on the ice water.

[0061] In this embodiment, the water purifier also includes a second water circuit, and the water tank 200, the first pump 400, the first switching valve 500, the heating pipe 600, the second switching valve 700 and the tea outlet 704 constitute the second water circuit. The water purifier also includes a tea cup 910. The tea cup 910 is fixedly arranged on the outside of the water purifier body 100 and is located on the left side of the water outlet 705. There is also a space reserved below the tea cup 910 for water collection. A tea outlet 911 is arranged on the tea cup 910, wherein the tea outlet 704 is connected to the tea cup 910. Under the action of the heating pipe 600, the tea outlet 704 of the second water circuit can discharge hot water of a set temperature, and the hot water directly enters the tea cup 910. Tea materials such as tea leaves can be placed in the tea cup 910, and the user can directly release the brewed and / or boiled tea at the tea outlet 911.

[0062] In this embodiment, the water purifier further includes a display screen 12. The display screen 12 is fixedly arranged above the water outlet 705 and is used to display operation prompts related to the water dispenser.

[0063] In this embodiment, the water purifier further includes a third water path, and the water tank 200, the first pump 400, the first switching valve 500, the heating pipe 600, the second switching valve 700 and the water outlet 705 constitute the third water path. When the heating pipe 600 turns on the heating function, the third water path can discharge hot water, and the hot water temperature can be set; when the heating pipe 600 does not turn on the heating function, the third water path can discharge water at room temperature.

[0064] In this embodiment, the water purifier further includes a fourth water circuit, which is composed of the refrigeration water circuit in the first water circuit and the third water circuit, so that the ice water in the ice water tank 300 is mixed with the water in the clean water tank 200 to form cold water. In this embodiment, the cold water temperature is 12-18 degrees. In this embodiment, temperature sensors are provided in the clean water tank 200 and the ice water tank 300, and the cold water of the temperature required by the user, the current water temperature in the clean water tank 200, and the water temperature in the ice water tank 30 are mixed and discharged.

[0065] In order to prevent bacteria problems caused by the machine not being used for a long time and the water inside the machine not being able to flow for a long time, this machine has added a "three-day non-use prompt for drainage operation". This action allows the user to switch the first switching valve 500 to the second drain port 503 to discharge water, so that the water in the clean water tank 200 is discharged into the ice water tank 300 in turn, and then turn on the second pump 800 to discharge the water in the first water circuit; after there is no residual water in the ice water tank 300 and the clean water tank 200, switch the first switching valve 500 to the first drain port 502 to discharge water, and finally switch the second switching valve 700 to the first discharge port 702 and / or the second discharge port 703 in turn to discharge water, and discharge the remaining water in the pipes in the second water circuit and / or the third water circuit. This process can realize the self-cleaning function of the entire water circuit, and basically discharge the water that has not flowed for a long time in the entire machine.

[0066] In this embodiment, the water purifier further includes a first exhaust pipeline 950, a second exhaust pipeline 951 and a third exhaust pipeline 952.

Since water vapor is easily generated during the heating or cooling process, multiple exhaust pipelines are added to discharge the water vapor to avoid excessive pressure in the pipeline.

[0067] In this embodiment, the water purifier also includes a shell 1, and the clean water tank 200, the ice water tank 300, the first pump 400, the first switching valve 500, the heating pipe 600, the second switching valve 700, the second pump 800 and the fixing bracket 900 are all arranged inside the shell 1.

[0068] The water purifier further includes a refrigeration component, which provides a refrigeration function for the ice water tank 300 .

[0069] like Figure 5 As shown, the refrigeration assembly includes a refrigeration element 2, which can refrigerate the water in the ice water tank 300 to ensure that the water in the ice water tank 300 is always kept at a relatively stable temperature value or temperature range. The refrigeration element 2 can be a semiconductor refrigeration sheet with a compact structure and small space occupation, and can ensure continuous and reliable refrigeration effect. When the water temperature in the ice water tank 300 reaches the set temperature, the refrigeration element 2 can change from high-power refrigeration to low-power heat preservation refrigeration.

[0070] The refrigeration assembly also includes a refrigeration block 301, which is integrally formed and includes a main body 302 and a fin part 303 connected to the main body 302. A mounting groove 305 is provided on the side wall 304 of the ice water tank 300, and a mounting hole 306 is provided on the bottom wall forming the mounting groove 305. The main body 302 is installed in the mounting groove 305 and connected to the refrigeration element 2 through thermal conductive silicone grease, and the fin part 303 passes through the mounting hole 306 and is located inside the ice water tank 300. The cold end of the refrigeration element 2 contacts the refrigeration block 301 so that the low temperature generated by the cold end of the refrigeration element 2 is transferred to the inside of the ice water tank 300 through the refrigeration block 301.

[0071] The water purifier further includes a heat sink 3 and a fan 4. The cooling element 2, the heat sink 3 and the fan 4 are all arranged in the housing 1, wherein the heat sink 3 is arranged between the cooling element 2 and the fan 4. Specifically, the heat sink 3 is in contact with the hot end of the cooling element 2, so that the high temperature generated by the hot end of the cooling element 2 is transferred to the heat sink 3, and the fan 4 is used to discharge the heat on the heat sink 3 out of the housing 1, thereby improving the heat dissipation efficiency.

[0072] like Fig.10 As shown, a groove 30 is formed on the heat sink 3, and the fan 4 is installed in the groove 30 by screws. Specifically, the heat sink 3 includes a plurality of heat sinks 31 arranged at intervals, and at least some of the heat sinks 31 are provided with a cutout 33 for installing the fan 4. The groove 30 is formed by the cutouts 33 on the plurality of heat sinks 31.

[0073] Air guide grooves 32 are formed between adjacent heat sinks 31 , and the cold air entering the housing 1 flows along the direction of the air guide grooves 32 .

[0074] like Figure 2 As shown, at least one air inlet 10 and an air outlet 11 are provided on the housing 1. The air inlet 10 and the air outlet 11 are located on the same side of the fan 4, and the air outlet 11 is arranged corresponding to the position of the fan 4, and the air inlet 10 is arranged corresponding to the position of the heat sink 3. In this embodiment, the at least one air inlet 10 includes a pair of air inlets 10, and the pair of air inlets 10 are arranged along the direction of the air guide groove 32 and are located on both sides of the air outlet 11. During the rotation process, the fan 4 can suck the cold air outside the housing 1 into the housing 1 through the air inlet 10 and reach the heat sink 3. The cold air flows along the direction of the air guide groove 32 of the heat sink 3 and takes away the heat on the heat sink 3 to form hot air. The multiple heat sinks 31 with fractures 33 on the heat sink 3 are "C-shaped" and completely wrap the fan 4. The fan 4 directly discharges the generated hot air outside the housing 1 through the air outlet 11. Compared with the solution of setting the air inlet 10 corresponding to the position of the fan 4, this solution can further ensure the heat dissipation effect and avoid the heat generated by the refrigeration plate from accumulating inside the machine and affecting the operation of other internal components.

[0075] like Figure 3As shown, the water purifier also includes a first air guide plate 5 and a second air guide plate 6, which are respectively located at the two ends of the air guide groove 32. By arranging the first air guide plate 5 and the second air guide plate 6, the cold air at the two air inlets 10 can be guided directly into the air guide groove 32 of the heat sink 31.

[0076] like Figure 5 and Fig. 9 As shown, the water purifier further includes a protective pad 7 , which is circumferentially arranged on the outer side of the refrigeration component 2 .

[0077] like Figure 5 and Fig. 9 As shown, the water purifier further includes a heat preservation member 8 , which is wrapped around the outside of the ice water tank 300 , and a through hole 80 is opened at a position of the heat preservation member 8 corresponding to the refrigeration block 301 , and the protective pad 7 is arranged in the through hole 80 .

[0078] like Figure 5 and Fig. 9 As shown, the water purifier further includes a seal 9 , which is disposed between the refrigeration block 201 and the housing 1 .

The float 20 is disposed in the ice water tank 300 . The low water level sensor 21 and the high water level sensor 22 are both disposed on the ice water tank 300 for detecting the position of the float 20 .

[0080] A slide rail 307 is provided in the ice water tank 300 , and a slide groove 308 is provided on the slide rail 307 . The float 20 is accommodated in the slide groove 308 and can move up and down along the direction of the slide groove 308 .
