The edge of the insertion part 311 fits with the groove wall of the ice-making groove, so that each ice-making groove is divided into multiple ice-making grids to produce granular ice cubes. The ice cubes in each ice-making groove are only separated by the insertion part 311, which makes full use of the space in the ice-making groove, which is conducive to making a large number of ice cubes.

[0046] It is understandable that in the related art ice making machine, only the bottom wall of the ice making grid is in contact with the evaporation pipe, and the heat transfer area is small, resulting in low ice making efficiency. In this embodiment, by providing the bottom plate flow section and the ridge flow section 351, the bottom wall and both side walls of the ice making grid can flow refrigerant, the heat transfer area is large, and the ice making efficiency is high.

[0047] In some embodiments of the present invention, the main shell 300 is an aluminum profile, the bottom plate flow section and the ridge flow section 351 both penetrate the main shell 300 in the transverse direction, and the main shell 300 is provided with two end covers 320, which are respectively provided at the left and right ends of all the bottom plate flow sections and all the ridge flow sections 351.

Among them, the two end plates can be fixedly connected to the main shell 300, and block the ends of all ice-making grids to prevent water leakage. At this time, all intermediate plates can be taken out upward from the main shell 300; of course, two additional covers 330 can be provided to block the two ends of the ice-making trough, so that the two end plates and all intermediate plates can be taken out upward from the main shell 300. At this time, the two end plates can also be provided with a connecting notch 312, and the end plates and the intermediate plates can be consistent.

[0050] In some embodiments of the present invention, the surface of the insertion portion 311 of the middle plate is provided with anti-skid protrusions.

After the water in the heat pump ice-making module is frozen into ice, it can be switched to the heating mode, so that the ice cubes are partially melted at the contact point with the main shell 300, which makes it easier to separate the ice cubes from the main shell 300.
