Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-8 This utility model provides a water distribution structure and a water purifier technical solution.

[0020] A water separation structure, comprising: Water distribution body 1, water distribution body 1 is provided with water distribution cavity 2, water distribution body 1 is provided with water distribution inlet 3, water distribution normal temperature outlet 4 and water distribution hot water outlet 5 connected to water distribution cavity 2, and water distribution hot water outlet 5 is lower than water distribution normal temperature outlet 4. The main water pump 6 includes a main water inlet 7 and a main water outlet 8, and the main water outlet 8 is connected to the branch water inlet 3. Hot water pump 9 includes a hot water pump inlet 10 and a hot water pump outlet 11. The hot water pump inlet 10 is connected to the hot water outlet 5.

[0021] The water distribution structure also includes a heating device 12, which includes a heating inlet 13 and a heating outlet 14. The heating inlet 13 is connected to the hot water pump outlet 11.

[0022] When hot water is needed, both the main water pump 6 and the hot water pump 9 are activated. The main water pump 6 draws outside water into the distribution chamber 2, while the hot water pump 9 draws water from the distribution chamber 2 through the hot water outlet 5 into the heating device 12. The heating device 12 heats the water and outputs it from the heating outlet 14. When room temperature water is needed, the hot water pump 9 is turned off, and the main water pump 6 is activated. When the water level in the distribution chamber 2 submerges the room temperature outlet 4, room temperature water can be output from the room temperature outlet 4. The room temperature water circuit does not require an additional water pump, resulting in a simple structure and low cost.

[0023] The water distribution structure also includes: The ice tank body 15 has an ice tank cavity 16 inside. The top of the ice tank body 15 has an ice tank inlet 17 that communicates with the ice tank cavity 16. The water distribution body 1 has a water distribution ice tank outlet 18 that communicates with the water distribution cavity 2. The water distribution ice tank outlet 18 is higher than the water distribution hot water outlet 5 and lower than the water distribution normal temperature outlet 4. The water distribution ice tank outlet 18 is connected to the ice tank inlet 17.

[0024] When water needs to be injected into the ice chamber 16, the hot water pump 9 is turned off, and the main pump 6 is started. When the water level in the distribution chamber 2 submerges the ice chamber outlet 18, water will enter the ice chamber 16 from the ice chamber inlet 17, thus filling the ice chamber 16 with water. Once the ice chamber 16 is full, the main pump 6 continues to work, and the water level in the distribution chamber 2 submerges the ambient temperature outlet 4, allowing ambient temperature water to flow from the ambient temperature outlet 4, thereby achieving the function of filling the ice chamber without the need for an additional pump.

[0025] like Figure 4 As shown, the water distribution structure also includes a water level sensor 19, which is electrically connected to the main water pump 6. When the water level in the water distribution chamber 2 is higher than the outlet 18 of the water distribution ice chamber, the water level sensor 19 receives an electrical signal. If room temperature water is required, the main water pump 6 continues to operate to output room temperature water when the water level sensor 19 receives an electrical signal.

[0026] like Figure 4 As shown, the water distribution body 1 also includes an ice bladder inlet chamber 20, which is connected to the water distribution chamber 2 via the water distribution ice bladder outlet 18. The ice bladder inlet 17 is located at the bottom of the ice bladder inlet chamber 20. A water level sensor 19 is installed inside the ice bladder inlet chamber 20. Water from the water distribution chamber 2 enters the ice bladder inlet chamber 20 through the water distribution ice bladder outlet 18, and then enters the ice bladder chamber 16 through the ice bladder inlet 17.

[0027] The water distribution structure also includes a refrigeration device 24 and a circulation pump 25. The side wall of the water distribution body 1 is provided with a circulation pumping channel 26 and a circulation conveying channel 27.

The ice chamber body 15 is provided with a circulation water outlet 32 ​​and a circulation water inlet 33 that communicate with the ice chamber cavity 16. The refrigeration device 24 is fixed on the side wall of the ice chamber cavity 16. The refrigeration plate 34 of the refrigeration device 24 is located inside the ice chamber cavity 16. The circulation water outlet 32 ​​is located away from the refrigeration plate 34, and the circulation water inlet 33 is located close to the refrigeration plate 34. The circulation pump 25 includes a circulation pump inlet 35 and a circulation pump outlet 36. The circulation pump inlet 35 communicates with the circulation water outlet 32, the circulation pump outlet 36 communicates with the circulation pumping inlet 28, the circulation pumping outlet 29 communicates with the circulation conveying inlet 30, and the circulation conveying outlet 31 communicates with the circulation water inlet 33.

[0028] The cooling element 34 of the refrigeration device 24 can cool the water in the ice chamber 16. Since the water temperature is higher at the location far from the cooling element 34 than at the location near the cooling element 34, the circulation pump 25 draws the water away from the cooling element 34 through the circulation water outlet 32 ​​and then pumps it back into the ice chamber 16 through the circulation water inlet 33, thus ensuring the uniformity of the water temperature in the ice chamber 16.

[0029] The water distribution structure also includes a three-way valve 40, which includes a first three-way connection port 37, a second three-way connection port 38, and a third three-way connection port 39. The first three-way connection port 37 is connected to the circulating water outlet 29, and the second three-way connection port 38 is connected to the circulating water inlet 30. When cold water needs to be output, the second three-way connection port 38 is closed, and the third three-way connection port 39 is opened, allowing the circulating pump 25 to draw cold water from the third three-way connection port 39. During normal circulation, the third three-way connection port 39 is closed, and the first three-way connection port 37 and the second three-way connection port 38 are open.

[0030] The circulating water inlet 33 is higher than the cooling element 34, and the water discharged from the circulating water inlet 33 is above the cooling element 34. The circulating water outlet 32 ​​is lower than the cooling element 34. In this way, the cooling element 34 can cool the water discharged from the circulating water outlet 32, resulting in better cooling effect.

[0031] A water purifier is also disclosed, including the aforementioned water distribution structure and a filter element 21. The filter element 21 includes a filter inlet 22 and a filter outlet 23. The main water outlet 8 is connected to the filter inlet 22, and the filter outlet 23 is connected to the water distribution inlet 3.

[0032] In addition, this water purifier is not limited to dispensing hot water, room temperature water, and ice water. The hot water output from the heating device 12 in the water purifier can also be connected to the coffee maker to provide hot water to the coffee maker, thereby realizing the coffee function.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
