Technical Field

The invention relates to the field of refrigeration equipment, in particular to an ice making box for a refrigerator and the refrigerator.

Background

At present, a refrigerator in a home uses an ice making housing combined by a plurality of small molds when making ice cubes. Such ice making boxes suffer from the following disadvantages: due to the relatively small space of the refrigerator, the ice making box occupies relatively valuable space of the freezing chamber of the refrigerator in use. Because of the relatively small once ice making amount, when more ice blocks need to be frozen, the refrigerator needs to be opened for many times, so that a plurality of repeated operations and high energy loss are caused; moreover, water is easy to spill during water injection. In addition, a complicated manual ice maker is available in the market, and because the ice maker needs to be provided with a torsion spring at one end of an ice tray to realize ice removal, the ice tray and the torsion spring are required to be fixed at one end of a shell, and the other end of the ice tray is required to realize rotary ice removal.

Each water injection pipe 72 has an upper end connected to one water injection port 75 and a lower end facing one ice tray structure 30 to inject water into the ice tray structure 30. The water injection pressing block 73 is provided at an upper end of the water injection cavity 71. The water injection pressing block 73 has a plurality of flow passages 74 on a circumferential wall thereof, and each flow passage 74 is provided corresponding to one water injection port 75, so that when the water injection pressing block 73 moves downward to press the water in the water injection cavity 71, the water in the water injection cavity 71 enters the corresponding water injection port 75 through each flow passage 74, and further enters each ice tray structure 30 through the corresponding water injection pipe 72. That is, when the water injection pressing block 73 is pressed downward, the water in the water injection cavity 71 flows upward to each water injection port 75 along each flow passage 74 by the water injection pressing block 73, and further flows into each layer of ice tray. Because the water injection pressing block 73 is adopted, the pressing pressure is consistent, the water quantity entering each water injection port 75 can be ensured to be uniform, and then multiple layers of ice grids can be filled at the same time.

The embodiment of the invention also provides a refrigerator which comprises a refrigerator body, a door body and the ice-making box in any embodiment. The ice making box is arranged or placed in the box body or the inner side of the door body.
