Abstract
An ice maker (100) includes an ice-making water tank (10), a water storage tank (20), a pipe assembly, a reversing member (40), and a driving member (50). The pipe assembly comprises a first branch pipe (310), a second branch pipe (320), and a third branch pipe (330). The first branch pipe (310) is connected to the water storage tank (20). The second branch pipe (320) and the third branch pipe (330) are separately connected to the ice-making water tank (10). The reversing member (40) is separately connected to the three branch pipes to control two of the branch pipes to be communicated and the rest one of the branch pipes to disconnected. The driving member (50) is connected to the third branch pipe in series. During ice making, the reversing member (40) controls the second branch pipe (320) and the third branch pipe (330) to be communicated and controls the first branch pipe (310) to be disconnected. The driving member (50) operates to drive the water to circulate among the ice-making water tank (10), the second branch pipe (320) and the third branch pipe (330).
