Problems solved by technology

[0006] In the usual fresh-keeping methods, for the fresh-keeping of meat products, whether it is frozen fresh-keeping at about -18°C or soft-freezing fresh-keeping at about -7°C, meat foods are preserved in a frozen state; vegetables and fruits The fresh-keeping method is usually carried out in an environment of about 5°C. The purpose of this is to ensure that the vegetables and fruits will not freeze, otherwise it will affect their appearance and taste, and sometimes even deteriorate and fail to achieve Fresh-keeping effect, but the fresh-keeping time of this fresh-keeping method is relatively short

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0031] The invention provides a refrigerator, which includes a freezer compartment, a refrigerator compartment and a supercooled fresh-keeping compartment. The freezer, refrigerated and supercooled fresh-keeping rooms are all provided with doors, wherein the freezer and refrigerated room realize conventional fresh-keeping functions, and the supercooled fresh-keeping room realizes the preservation of food in a supercooled state. The position of the supercooled fresh-keeping room Located between the freezer and refrigerator.

[0032] The freezer and refrigerator of the present invention are the same in structure and control as conventional refrigerators. The supercooled fresh-keeping room adopts a sandwich structure above the structure, the outer part is an insulating layer, and the cavity formed by the inner layer is used to store food that need...

Abstract

A novel electric refrigerator, comprises: an air cooling system, as well as a super-cooling fresh-keeping chamber connected with the air cooling system through an induced duct and a backwind tube, and further comprises a cooling chamber and a refrigeration chamber; wherein the super-cooling fresh-keeping chamber is arranged under the cooling chamber and on the refrigeration chamber and comprises an internal chamber and external chamber with certain space therebetween. The control method of the novel electric refrigerator comprises: sensing the temperature of the super-cooling fresh-keeping chamber by a temperature sensor; sending out an instruction by a microcontroller according to the temperature to control the operation of a driving circuit; and controlling a fan to work by the driving circuit to introduce cold airflow until the super-cooling fresh-keeping chamber is maintained in a super-cooling state. The invention is characterized in that foods are kept fresh in a normal refrigeration temperature without freezing.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and relates to a refrigerator, in particular to a refrigerator with a function of supercooling and freshness preservation and a control method thereof. Background technique [0002] The fresh-keeping methods of traditional refrigerators can be roughly divided into three types: 1. Meat products that need to be kept fresh for a long time are placed in the freezer at a temperature of about -18°C for frozen storage; 2. Meat products that are kept fresh for a short time are usually placed Soft-frozen storage is carried out at a temperature of about -7°C in a variable temperature room; 3. Vegetables and fruits are stored in a refrigerator at a temperature of about 5°C. [0003] Modern scientific research shows that animal and plant foods are composed of cells. Among them, fruit and vegetable plants are composed of soft cell groups surrounded by cellulose and pectin, and there are gas gaps betwee...
