Embodiment Construction
[0036] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0037] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a food freezing device, a refrigerator and a food freezing control method. The food freezing device comprises a freezing box, a pressurization mechanism, a refrigeration mechanism and a depressurization mechanism. A freezing chamber is formed in the freezing box. The pressurization mechanism is used for pressurizing the freezing chamber to the pressure higher than or equalto first preset air pressure. The refrigeration mechanism is used for lowering the temperature of the freezing chamber to be lower than or equal to the first preset temperature. The depressurizationmechanism is used for lowering the pressure of the freezing chamber to be lower than or equal to the second preset air pressure. The first preset air pressure is higher than the standard atmospheric pressure. The second preset air pressure is lower than the first preset air pressure and is higher than or equal to the standard atmospheric pressure. The first preset temperature is lower than or equal to the freezing point of water under the standard atmospheric pressure. Simultaneous freezing of the surface and interior of food can be ensured, freezing uniformity of the food is ensured, the freezing speed of the food can be increased significantly, and thus ice crystals formed after food freezing are small in size, low in hardness and mellow and full in shape.
Description
technical field [0001] The invention relates to the technical field of freezing, in particular to a food freezing device, a refrigerator and a food freezing control method. Background technique [0002] With the development of the economy and the progress of the society, people are more and more pursuing the quality of life. Refrigeration equipment such as refrigerators are widely used in people's daily life and become an indispensable tool in people's life. Refrigerators generally have a freezing compartment for freezing food so that the food can be stored for a long time. [0003] According to the principle of freezing, the faster the freezing speed of the liquid during the freezing process, the smaller the ice crystals formed, the lower the hardness and the rounder the shape, and the ice crystals with smaller volume and lower hardness can achieve thawing without thawing. Processing can be realized under certain conditions, and the rounder ice crystals will cause less dam...
