Air circulation intelligent defrosting refrigerator

Abstract

The invention discloses an air circulation intelligent thawing refrigerator, which relates to the field of household appliances. In existing household refrigerators, rapid thawing of food affects the taste and causes loss of nutrients, and manual operations are required to thaw food in the refrigerator. The air circulation intelligent thawing refrigerator uses single-chip microcomputer control technology and air circulation technology to realize scheduled thawing. It includes multiple insulated and independently temperature-controlled freezers and refrigerators. The refrigerators and freezers are connected by air inlet pipes and return air pipes. The solenoid valve and air pump are installed on the air inlet pipe and the air return pipe. The single-chip microcomputer system controls the solenoid valve and air pump. The circulating air carries the heat of the refrigerator room and slowly flows into the freezer room. The frozen food is slowly and automatically thawed at the user's appointment time. The nutrition and taste of the food are preserved to the greatest extent. At the same time, due to the design of multiple independently insulated freezer compartments and the slow flow of cold capacity from the freezer compartments into the freezer compartment, it saves electricity compared to existing refrigerators.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a household refrigerator. Background technique [0002] The temperature change curve of the frozen food in the existing refrigerator is as follows: figure 2 As shown, in stage 1, the food is cooled and frozen; in stage 2, the food is in frozen storage; in stage 3, the food is taken out of the refrigerator and placed on the thawing plate to thaw naturally; Thaw in warm water or in the microwave. At the dinner table, the fast-thawed meat tastes like wood, and some of the food is left over and thrown away. [0003] For experienced users, when the frozen food is transferred from the freezer to the refrigerator, the temperature of the food changes as follows: image 3 As shown in the temperature change diagram of thawing frozen food in the refrigerator, stage 1, the food is cooled and frozen; stage 2, the food is in the freezer; stage 3, the food is slowly thawed in the refri...

AI Technical Summary

Problems solved by technology

In the end, there was only quick thawing, because the taste was too bad, some of the food was still thrown away

Thawing is inconvenient, users are either unwilling to use the freezer, or the freezer is full and there is no time to defrost and cook
