Description

Technical Field

[0001] This utility model relates to the technical field of water purifiers that can both make ice and cool water, specifically a water purifier that can both make ice and cool water. Background Technology

[0002] CN115451627A discloses an ice-making device that can continuously extrude ice blocks. However, this machine can only produce ice blocks. Its principle is that water is frozen in the ice-making tube and then extruded by a spiral cutter. During the extrusion process, the water passes through an ice guide plate and is extruded into ice blocks of a specific shape.

[0003] Since it lacks a cooling function, customers often have to use ice cubes to cool the water before drinking it, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a water purifier that can both make ice and cool water, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water purifier capable of both making ice and cooling water, comprising a pure water cup, an upper water tank, and an ice maker. Water from the pure water cup is pumped into the upper water tank via a water replenishment pump. The upper water tank is equipped with an overflow port. The purifier further comprises a cold water tank and a reversing valve. The upper water tank is also equipped with an outlet. The reversing valve has ports A, B, and C. The outlet on the water tank is connected to port A. Port B is connected to the outlet of the impeller pump. Port C is connected to the bottom inlet of the ice maker. The inlet of the impeller pump is connected to the outlet of the cold water tank. The cold water tank is connected to the cold water outlet of the ice maker. Water in the cold water tank is pumped to the faucet via a cold water pump. During the ice-making process, the water replenishment pump pumps pure water into the upper water tank. The reversing valve (in a de-energized state) is open at its AC end, allowing water to flow naturally from the upper water tank into the ice maker. After being made into ice, the water enters the ice chamber until the ice chamber is full. In the cooling process, the cold water tank is replenished to the high water level through the overflow port of the upper water tank. The reversing valve is then energized, switching the water circuit to the BC terminal for conduction. The impeller pump continuously draws cold water from the cold water tank to supply the ice maker. After being cooled by ice cubes in the ice maker, the cold water becomes ice water and enters the cold water tank, lowering the water temperature there. This process repeats until the water temperature in the cold water tank reaches the set value. At this point, the cold water pump is activated, drawing water from the cold water tank and delivering it to the tap, thus obtaining ice water.

[0006] Compared with existing technologies, the advantages of this invention are as follows: During the ice-making process, the water pump delivers pure water to the upper water tank. The reversing valve (in a de-energized state) is activated at its AC end, allowing water to naturally flow from the upper tank into the ice maker. After ice is formed, it enters the ice chamber until the ice chamber is full. During the cooling water process, the cold water tank is replenished to a high water level through the overflow port of the upper water tank. The reversing valve is energized, and the water circuit switches to the BC end, causing the impeller pump to continuously draw cold water from the cold water tank and supply it to the ice maker. After being cooled by the ice cubes in the ice maker, the cold water becomes ice water and enters the cold water tank, lowering the water temperature there. This process repeats until the water temperature in the cold water tank reaches the set value. At this point, the cold water pump is activated, drawing water from the cold water tank and delivering it to the faucet, thus obtaining ice water. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] See Figures 1 to 7 This utility model embodiment provides a water purifier that can both make ice and cool water, including a pure water cup 1, a water replenishment pump 2, an upper water tank 3, a reversing valve 4, an impeller pump 5, an ice maker 6, a cold water tank 7, a cold water pump 8, and a faucet 9.

[0016] The pure water cup 1 stores purified water. The water replenishment pump 2 is responsible for transporting the water in the pure water cup 1 to the upper water tank 3. The upper water tank 3 has an overflow port 31 and a water outlet 32. The overflow port 31 is connected to the cold water tank 7, and the water outlet 32 ​​is connected to the reversing valve 4.

[0017] The reversing valve 4 has three ports, namely port A, port B and port C. The water outlet 32 ​​is connected to port A, port B is connected to the outlet of the impeller pump 5, and port C is connected to the ice maker 6.

[0018] The inlet of the impeller pump 5 is connected to the cold water tank 7.

[0019] The ice maker 6 includes an ice-making tube 61, a spiral cutter 62, and an ice chamber 63. An evaporator sleeve 64 is fitted over the ice-making tube 61. The evaporator sleeve 64 has a coolant inlet and an outlet. Liquid coolant enters through the inlet, turns into gas, and exits through the outlet, carrying away heat from the evaporator and ice-making tube in the process. A water inlet is located at the bottom of the ice-making tube 61 and is connected to the reversing valve C port.

[0020] The spiral reamer 62 is driven to rotate by a motor. The spiral reamer 62 is provided with a water passage hole 621, the inlet of which is located inside the ice-making tube 61, and the outlet of which is located at the top of the spiral reamer 62.

[0021] The bottom of the ice chamber 63 is higher in the middle and lower around the perimeter. A first through hole 631 is provided at the middle position of the bottom of the ice chamber 63, and an ice guide plate 65 is provided on the first through hole 631.

[0022] The top of the ice-making tube 61 is connected to the first through hole 631.

[0023] It also includes an isolation plate 66, which is disposed at the bottom of the ice chamber 63. A flow guide 661 is disposed in the middle of the isolation plate 66. The flow guide 661 is located at the opening of the first through hole 631. An overflow port 662 is provided between the flow guide 661 and the bottom of the ice chamber 63.

[0024] The ice chamber 63 is provided with a second through hole 632 around its perimeter, and the second through hole 632 communicates with the cold water tank 7.

[0025] A stirrer 622 is mounted on the top of the spiral auger 62, and rotates together with the spiral auger 62. A stirring rod 623 is arranged around the periphery of the stirrer 622, extending towards the partition plate 66. A water passage 624 is provided inside the stirrer. After water flows out from the top of the spiral auger, the water passage 624 guides the water to the side of the stirrer for exit. The portion of the side of the stirrer 622 above the ice guide plate 65 is conical. When ice blocks extruded from the molding hole contact the conical surface, they can be broken. In use, the spiral auger rotates, driving the stirring rod to rotate. As the stirring rod rotates, it conveys the ice blocks in the ice chamber to the outlet. Water flowing out from the outlet at the top of the spiral auger passes through the water passage inside the stirrer and exits from the outlet on the side of the stirrer.

[0026] The agitator 622 is equipped with a guide pipe 62a, and the top of the spiral auger 62 communicates with the guide pipe 62a. The guide pipe 62a has outlets 62b on both its top and side. The presence of outlets on both the top and side prevents clogging.

[0027] The ice guide plate 65 is provided with multiple shaping holes 651. The shape of the shaping holes directly determines the shape of the ice block.

[0028] The isolation plate 66 is provided with ribs 662. When the stirring rod moves the ice block, it can lift the bottom of the ice block when passing the ribs, thus preventing the bottom of the ice block from sticking to the isolation plate.

[0029] The cold water tank 7 is connected to the cold water pump 8, and the cold water pump 8 is connected to the faucet 9.

[0030] During ice making, the water pump delivers pure water to the upper water tank, and the AC end of the reversing valve (in the off-power state) is turned on, so that the water level in the upper water tank is the same as that in the evaporator and is at a high water level. The compressor works, and after the ice outlet of the ice making tube passes through the ice guide plate, ice of a specific shape is squeezed out until the ice chamber is full of ice.

[0031] When cooling water is being supplied, the cold water tank is replenished to the high water level through the overflow port of the upper water tank. The water circuit on the reversing valve is switched to the BC terminal for conduction, and the impeller pump continues to work to supply water to the evaporator. At the same time, the compressor works, and the water in the cold water tank is flushed from the ice-making pipe into the drainage shroud. The water flows out from the bottom of the drainage shroud to wash away the ice in the ice outlet and melt it. Before the ice melts, the excess water flows out from under the ice-water separation plate and returns to the cold water tank. After the ice in the ice outlet melts, the water flows out from the second through hole, and the cycle continues to achieve the purpose of cooling water.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
