Fresh-keeping device with good fresh-keeping effect and control method for fresh-keeping device

Abstract

The invention provides a fresh-keeping device with a good fresh-keeping effect and a control method for the fresh-keeping device. The fresh-keeping device comprises a refrigerating device, a fresh-keeping box, and a heat exchange accelerating mechanism which is arranged in an inner container and used for accelerating the gas flow rate in the inner container. According to the fresh-keeping device with the good fresh-keeping effect and the control method for the fresh-keeping device, a secondary refrigerant is arranged between a shell and the inner container, the influence caused by environmenttemperature fluctuation is avoided through the buffering effect of the secondary refrigerant, then the temperature fluctuation in the inner container is controlled within the range of +/-0.2 DEG C, sothat food spoilage is avoided, the eating quality of food is guaranteed, the storage period of food is prolonged, meanwhile, the gas flow rate in the inner container is increased through the heat exchange accelerating mechanism, thus the heat transfer rate in the inner container is increased, in addition, the heat transfer rate and the heat transfer area are increased through corrugated plates made of metal, the heat transfer rate is further increased, so that the pre-cooling time is greatly shortened, and the fresh-keeping effect of the fresh-keeping device is improved.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping equipment, in particular to a fresh-keeping device with high fresh-keeping effect and a control method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the freshness of food quality are getting higher and higher. The existing fresh-keeping storage methods all use refrigerators for refrigeration or freezing for storage, but the ice crystals formed under freezing conditions will Puncture the cells, resulting in the loss of juice and the reduction of nutrient content. However, when the traditional refrigerator refrigerates the food, it cannot be stored for a long time due to the fluctuation of the ambient temperature, and it is prone to spoilage. Both methods have the problem of declining food quality. Contents of the invention [0003] In order to solve the technical problem of the quality reduction of the screen in the way of foo...
