Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific examples are only used to explain the present invention, but not to limit the present invention.

[0024] Ordinary refrigerators generally include a refrigerator and a freezer. Foods that need to be preserved, especially high-protein foods such as meat and fish, should be frozen and stored in the freezer. During freezing, the food cools from the surface until the center of the food is completely frozen. Due to the uneven temperature of this freezing process, large needle-shaped ice crystals are easy to form from the surface of the food to the center, and the large needle-shaped ice crystals will destroy the structure of the food itself, resulting in the reduction or loss of the nutritional content of the f...

Abstract

The invention discloses a refrigerator and an instant freezing and refrigerating control method thereof. The control method comprises the steps that when a refrigerator controller detects that the temperature of food placed in an instant freezing chamber is larger than a set temperature T, an instant freezing program is controlled to be started, the instant freezing program controls the temperature in the instant freezing chamber in a staged mode, and the food is made to reach the frozen state through a pre-cooling temperature reduction stage, a stepped temperature reduction stage and a supercooling relieving stage and then returns to a partial freezing stage for freezing storage. According to the control method, the intelligent operation problem of the instant freezing chamber of the refrigerator is well solved, and the nutrition of frozen meat is kept to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator and a method for controlling a freezer chamber thereof. Background technique [0002] In order to keep food fresh, it is common practice to store food in a lower-temperature freezer compartment of the refrigerator so that its temperature gradually reaches the frozen storage temperature. This kind of freezing method takes a long time. The food is first frozen from the outside and then gradually frozen inward. The freezing temperature of the food is uneven, which will cause the food to stay in the area of ​​​​the largest ice crystal formation zone for a long time. This situation is easy to destroy the nutrition of the food. In order to better keep the nutrition of frozen food, there are also people who propose the method of quick freezing and then preserving food. Chinese patent CN105043009A has proposed a kind of frozen preservation method of refrigerator, an...
