Refrigerator preservation box, refrigerator and food fresh keeping control method

Abstract

The invention discloses a refrigerator preservation box, a refrigerator and a food fresh keeping control method, belongs to the technical field of refrigerators and control method thereof, and aims to solve the problems that the existing refrigerator is poor in fresh keeping effect during refrigeration and short in storage cycle during cold storage. The refrigerator preservation box comprises a preservation box body, a heating device in the preservation box body, a cool air adjustment structure arranged at the rear of the preservation box body and a temperature detection element, wherein the cool air adjustment structure is used for enabling foods in the preservation box body to enter and be kept in an excessive cooling state; the temperature detection element is used for detecting temperature in the preservation box body; and the heating device is used for heating the foods in the preservation box body to a preset temperature. The refrigerator disclosed by the invention comprises a chill compartment and the refrigerator preservation box and is excellent in fresh keeping effect and user experience. The invention further provides the food fresh keeping control method based on the refrigerator, and with adoption of the method, the foods are kept fresh within at least one week.

Description

technical field [0001] The invention relates to the technical field of refrigerators and control methods thereof, in particular to a fresh-keeping box for a refrigerator, a refrigerator with the fresh-keeping box, and a food preservation control method based on the refrigerator. Background technique [0002] With the improvement of residents' living standards, residents have higher and higher requirements for keeping food stored in refrigerators. Usually, foods such as fish and meat need to be stored in a freezer (temperature ≤ -18°C), and foods such as vegetables and fruits need to be stored in a freezer (temperature is about 5°C). [0003] When freezing, the food starts to freeze from the surface, and the surface temperature has quickly passed through the maximum ice crystal formation temperature zone, but the internal temperature of the food has not yet passed through or is still in this maximum ice crystal formation temperature zone, and the formed ice crystals are large...

Problems solved by technology

In addition, there are also some problems in thawing food, such as the thawed food must be used up at one time, the thawing is uneven when thawing in the microwave oven, it takes a long time to thaw once it is frozen, and the taste of the thawed food becomes poor, etc.

When refrigerated, due to factors such as bacterial reproduction and oxidation, the storage time can only be guaranteed for about 2-3 days, and the storage period is short
