Improved refrigerator with temperature-variable room

Abstract

An improved refrigerator with a cool select zone comprises a refrigerating room, a cold room, the cool select zone and a control part. The cool select zone is arranged in the cold room and provided with an air inlet and an air outlet. The refrigerator also comprises an induced duct, one end of which is connected with the refrigerating room and the other end of which is connected with the air inlet of the cool select zone; as well as an air quantity control structure connected with the induced duct. The control method for the refrigerator comprises: when T is more than Ts-0.5, a controller opens an electric air door to lead cooling air and the on-state of an evaporator fan is retained, if the fan stops, the fan is forcedly started to speed up the flow of cooling air and lower the temperature; when T is less than Ts-0.5, the controller closes the electric air door, the fan recovers to the normal operating state for heat preservation. The refrigerator can conveniently set the temperature to satisfy the fresh-keeping requirements of most daily food; moreover, the refrigerator has the advantages of simple structure, high speed of temperature change, wide regulation range, no remaining frost formation, etc..

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, and relates to a refrigerator, in particular to a refrigerator with a temperature changing function. Background technique [0002] Existing refrigerators on the market, such as side-by-side refrigerators, mostly include independent freezing chambers and refrigerating chambers, which are respectively located on the left and right sides of the refrigerator cabinet. The refrigerating room is located on the right side of the cabinet and takes up a lot of space, but its storage temperature can only be adjusted within a very limited range above 0°C, which contradicts the diverse temperature needs of users for preserving food. Existing temperature-changing greenhouses on the market use the method of digging holes on the side of the freezer to introduce cold air and conduct heat transfer in the form of natural convection. Since the temperature-changing greenhouses in this way are directly c...

AI Technical Summary

Problems solved by technology

Existing temperature-changing greenhouses on the market use the method of digging holes on the side of the freezer to introduce cold air and conduct heat transfer in the form of natural convection. Since the temperature-changing greenhouses in this way are directly connected to the freezing chamber, the humid gas in the temperature-changing will enter the freezer and form residual frost on the side of the freezer

At the same time, natural convection is used for heat transfer, so the cooling rate is relatively slow

In short, the existing temperature-changing greenhouses usually have many disadvantages such as small temperature adjustment range, slow temperature change speed, and frosting on the side of the freezer due to improper structure and control methods.
