In the prior art, since ice making machines such as refrigerators and ice making machines on the market generally appear in the catering industry, but the household rate of the refrigerators is far higher than that of the ice making machines, a user can not spend money to purchase an ice making machine on the premise of buying the refrigerators, and generally, the user can put an ice mold of plastic, soft rubber or other materials into a freezing cavity of the refrigerators, and inject water into the ice mold to make ice cubes by using static ice making. Similarly, some ice machines make ice using a similar static water ice making principle, i.e., an ice mold is filled with water and placed in a freezer for direct freezing. However, more bubbles are generated in ice cubes made by the ice maker or the refrigerator applying the static ice making method, so that the permeability of the made ice cubes is poor, the freezing time of the ice cubes and the freezing effect of the ice cubes are greatly reduced, and the experience of users is greatly reduced. In addition, most ice makers make ice by using the principle of making ice by using flowing water in order to ensure the permeability of ice cubes, but the ice making efficiency of the ice maker is low, and the experience of users is also reduced.

It can be understood that when the water body in the ice making mold 100 is the water body degassed by the degassing mechanism 300, and the ice cubes prepared by the ice making device have better permeability, the mold turning mechanism 500 is configured to turn to one side, so that the ice cubes with better permeability drop into one of the ice storage cavities 610 after being separated from the ice making mold 100 through the ice making port 111, and at this time, if a user needs high-quality ice cubes, the high-quality ice cubes can be taken out from the ice storage cavity 610; when the water body in the ice making mold 100 is not deaerated by the deaeration mechanism 300, and thus the ice making device may make ice cubes having poor permeability, the mold turning mechanism 500 is configured to turn over to the other side, so that the ice cubes having poor quality may drop out of the ice making mold 100 through the ice making port 111 to the other ice storage cavity 610, and at this time, if a user needs the ice cubes, the ice cubes may be taken out of the ice storage cavity 610. Above, bring very big facility for the user, greatly promoted user's use experience.

In this embodiment, the ice making device may make both normal ice and transparent ice, and may store ice independently. And the working process of the ice making device can be as follows:

when transparent ice is required to be made, the water supply unit is communicated with the water injection pipe 210 by the three-way valve 410, water is firstly subjected to degassing treatment by the degassing mechanism 300, then enters the ice making cavity 110 of the ice making mold 100 through the water injection nozzle 230 to make ice cubes, and the ice making mold 100 can rotate clockwise after ice making is completed, so that ice removing is completed. When water enters the degassing mechanism 300, the vacuum pump 331 starts to operate, bubbles overflow from the degassing membrane 310 under the action of negative pressure environment along with the water flowing, and when the pressure in the water passing cavity 321 reaches a first set pressure value, the pump stops. When the pressure in the water through cavity 321 is detected to be greater than the second set pressure value, wherein the second set pressure value is greater than the first set pressure value, the vacuum pump 331 is restarted until the pressure in the water through cavity 321 returns to the first set pressure value again. After repeating the preset times, the valve provided on the water injection nozzle 230 is opened to perform the water injection and ice making task. In contrast, when it is desired to make normal ice cubes, the three-way valve 410 communicates the water supply unit with the water supply pipe 220, and performs an ice making task.
