Refrigerator

Abstract

The invention relates to a refrigerator and provides a refrigerator capable of preventing vegetables or fruits from being frozen due to the freezing temperature of the freezer of the refrigerator and preventing the air door device of the refrigerator used for providing cold air to a vegetable chamber from being frozen. The refrigerator comprises a vegetable chamber and containers arranged inside the vegetable chamber. The refrigerator is characterized in that a vegetable chamber cold air outlet is arranged on the rear part of the upper surface of the vegetable chamber. An air door device arranged at the vegetable chamber cold air outlet for controlling the cold air amount supplied to the vegetable chamber comprises an air door housing and an air door housing cover. The air door housing is equipped with a baffle for opening and closing a cold air channel. The air door housing cover covers the air door housing with a gap therebetween. One side of the insulation baffle inside the vegetable chamber is equipped with a cold air return channel and a heating mechanism for heating the cold air return channel and the vegetable chamber through the cold air return channel.

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] As the background technology in this technical field, there are Japanese Patent Laid-Open Publication No. 8-303931 (Patent Document 1: Japanese Patent Laid-Open Publication No. 8-303931), Japanese Patent Publication No. 6-18177 (Patent Document 2: Japanese Patent Publication 6- 18177) and JP-A-2010-60187 (Patent Document 3: JP-A-2010-60187). [0003] Patent Document 1 describes the following refrigerated refrigerator: In a refrigerator that is divided into a refrigerator compartment, a freezer compartment, and a vegetable compartment from above by an insulated box and a partition wall, and cool air is circulated by a cooler and an air blower, The air channel for conveying cold air in the above-mentioned freezer compartment is connected to the above-mentioned vegetable compartment. In addition, a damper device is provided on the partition wall portion of the air passage lead...

AI Technical Summary

Problems solved by technology

Therefore, when the vegetable compartment door is opened, a large amount of dew condensation will be generated on the vegetable compartment damper due to the temperature difference of the heating air flowing into the vegetable compartment, and as a result, it may freeze.

In addition, a large current flows through the drive motor and is applied to the motor coil or the mechanical drive unit, which may cause damage

[0008] In addition, in Patent Document 3, there is no description that the cold air return passage for the vegetable compartment formed on the heat-insulating partition wall is cooled by the freezing temperature of the freezer compartment, and there is a possibility that food such as vegetables or fruits stored in the vegetable compartment may freeze.
