Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to an ice making machine with an ice tank having a circulating water return function. Background Art

[0002] The existing Chinese patent with announcement number CN 210532775U discloses an ice-making module and an ice-making machine, wherein the ice-making module comprises: an inner tank, a partition and an ice-discharging screw, wherein the inner tank is installed in the inner tank, the partition divides the inner tank into an ice storage chamber and a water storage chamber, the water storage chamber is located below the ice storage chamber, and an ice-discharging outlet is arranged on one side of the ice storage chamber; the ice-discharging screw is rotatably installed in the ice storage chamber, and when the ice-discharging screw rotates, the ice-discharging screw is used to bring the ice cubes in the ice storage chamber out of the ice-discharging outlet; an air-avoiding portion is arranged at one end of the partition away from the ice-discharging outlet or at the inner side surface of the inner tank away from the ice-discharging outlet, and the upper surface of the air-avoiding portion comprises an air-avoiding surface, and the air-avoiding surface is inclined from bottom to top toward a direction away from the ice-discharging outlet.

[0003] However, the above-mentioned ice maker has the following disadvantages: the melted water in the ice storage chamber of the ice maker will fall vertically into the water storage chamber located below, but the accumulated water in the water storage chamber is used to prepare hot water. However, when the hot water is not consumed for a long time, since the water storage chamber does not have a water circulation function, the liquid level in the water storage chamber will continue to rise until it overflows. At this time, the accumulated water in the water storage chamber can only be poured out, but the long-term accumulation of water in the water storage chamber is prone to breed bacteria, so it is urgent to develop an ice maker with a circulating water return function. Utility Model Content
