Description
Technical Field
The invention relates to the field of refrigeration equipment, in particular to a quick-freezing disc for a refrigerator, the refrigerator and a control method of the refrigerator.
Background
It is known that when food is frozen or thawed, cell damage and nutrient loss on the surface of the food can be greatly reduced, and the freshness of the food can be maintained. At present, in a direct-cooling refrigerator, when food is refrigerated and frozen in the refrigerator, cold energy is transferred mainly by natural flow of air, the process is quite slow, and the effects of quick cooling and quick freezing cannot be achieved, so that the fresh-keeping time of the frozen or refrigerated food is short, and the moisture and nutrition loss is serious. In an air-cooled refrigerator, the contents of a quick-freezing tray are usually frozen quickly by using cold air. However, the direct cooling by cold wind easily takes away a large amount of water on the surface or inside of the article, so that water and nutrition are lost, and the taste is reduced. Due to the obstruction of the articles, the cold air circulation is not smooth, and the cold quantity transmission quantity is reduced and slowed down. Therefore, the problems of low local refrigeration speed and uneven temperature can occur, so that the frost cracking of cell walls, the loss of nutrients in the food and the reduction of mouthfeel of the food can be caused in the freezing process, and the requirement of a user on quick freezing of real objects can not be met. Moreover, after the quick-freezing tray is placed in the freezing chamber, the airflow flow can affect the temperature distribution in the freezing chamber, can affect the storage of other articles, and can affect the quality of other articles.
In addition, sometimes a user needs to quickly freeze the whole piece of rare deep-sea fish so as to ensure the taste of the fish, and a quick-freezing disc in the existing refrigerator is small and cannot be opened; and the fish meat is placed on the existing freezing tray, the freezing speed is low, and ice crystals easily pierce the cell walls of the fish meat to influence the taste in later-stage production. In addition, in the existing quick-freezing tray technology, the body is an aluminum tray with a certain thickness, a heat pipe is arranged in the aluminum tray, and the quick-freezing function is realized through the heat pipe, or a metal tray with a large volume is utilized, and the characteristic of high heat conduction rate of metal is utilized to realize the quick-freezing function. However, the existing quick-freezing tray scheme has the defects that the tray cannot be made too large, and if the tray is made too large, a whole aluminum block is too high in cost and too heavy, and is inconvenient to take; the scheme of the existing metal plate is mostly formed by stamping a stainless steel plate and is placed at the bottom of the drawer, and the defects that the plastic drawer is separated when the large surface of the metal plate and cold air exchange, so that the heat exchange rate is reduced.
