[0002] At present, in order to improve the transparency and uniformity of the ice cubes made by an ice maker, a water stirring mechanism is generally arranged in an ice making box. However, most of the current water stirring mechanisms agitate water by driving a stirring rod with a motor, so that the water in the ice making box has a certain fluidity, so as to achieve the above effects. The existing water stirring mechanism has a relatively complex structure and requires a separate motor drive. Summary of the Utility Model

[0003] In view of the technical problems in the prior art, the utility model provides a water circulation water stirring mechanism of an ice maker, which includes a water box and an ice making evaporator. The ice making evaporator is installed in the water box, and further includes a water circulation mechanism. The water circulation mechanism includes a water inlet waterway and a circulation waterway. The water inlet waterway communicates with a water inlet pipe and the water box, and conveys the water in the water inlet pipe to the water box through a water pump. The circulation waterway communicates with the water inlet waterway and the water box, and conveys the water in the water box back to the water box through the water inlet waterway through a water pump. When in the water inlet working state, the water inlet waterway is opened, and the circulation waterway is closed. When in the ice making and water stirring working state, the circulation waterway is opened, and the water inlet waterway is closed.

[0004] Further, the water inlet waterway includes a water inlet pipe, and the circulation waterway includes a return pipe. The water inlet pipe and the return pipe are both installed in the water box. One ends of the water inlet pipe and the return pipe extend out of the water box and are mutually communicated with the water inlet pipe through a three-way valve. The water pump is installed outside the water box and is located between the water inlet pipe and the three-way valve.

[0005] Further, a plurality of small holes are spaced along the length direction on both the water inlet pipe and the return pipe. The water inlet pipe is installed at the bottom of the water box, and the return pipe is installed at one end of the water box close to the top. The water inlet pipe and the return pipe both realize water exchange with the water box through the small holes.

[0006] Further, the small holes on the water inlet pipe are opened at one end of the water inlet pipe close to the bottom of the water box, and the small holes on the return pipe are opened at one end of the return pipe close to the top of the water box.

[0007] Further, one end of the water inlet pipe is installed in the water box, and the other end of the return pipe is installed in the water box. The water inlet pipe and the return pipe both realize water exchange with the water box through the ends.
