Abstract

The invention provides a refrigerator in which the situation that a baffle plate is not frozen and cannot be opened because of frost and cooling air cannot be induced into a refrigerating chamber. A single-evaporator type refrigerator (1) is characterized in that an opening (15) communicating with the refrigerating chamber (4) is opened on a part of a cooling air passage; a baffle plate (17), a baffle plate drive electric motor (30) and an electric motor control device (25) are arranged on the opening. The electric motor control device (25) has a first control mode which uses the baffle plate to keep the opening in a close state or an open state by rotating the baffle plate drive electric motor and a second control mode which electrifies an coil of the baffle plate drive electric motor to heat the coil without making the baffle plate have open and close actions.

Description

technical field [0001] The present invention relates to a single evaporator type refrigerator having a function of opening and closing a damper mechanism for introducing cold air passing through a cold air passage into a side of a refrigerator compartment. Background technique [0002] Conventionally, as a single evaporator type refrigerator characterized by the control of the baffle mechanism for cooling the freezer compartment and cooling the refrigerator compartment / vegetable compartment with cold air cooled in one evaporator, we know JP-A 10- Refrigerator described in Publication No. 89833 (Patent Document 1). This conventional refrigerator is characterized in that the motor-driven shutter is miniaturized, and the shutter driving motor is periodically energized to open the shutter in a state where the opening is blocked so that cold air does not leak from the cold air passage to the refrigerator compartment. action. [0003] Such refrigerators of the prior art are cont...
