変化又は大きさを前記制御回路部によって検出して、電動機５５の回転を停止する。 In the damper device 50, the electric mechanism 51 is operated by the control circuit unit based on the temperature detection of the sensor that detects the temperature of the refrigerator compartment 3, and the operation plate 52 opens and closes the opening 54. Specifically, when the temperature of the refrigerator compartment 3 is cooled to a predetermined set lower limit temperature, the motor 55 is controlled by the control circuit unit.
When a pulse signal in the forward rotation direction is supplied to the motor 55, the electric motor 55 rotates forward and the operating plate 52 is opened.
4 is rotated in the closing direction. When the operation plate 53 closes the opening 54 by this forward rotation,
Both elastic members 72 and 73 are pressed against each other, and the cold air passage is closed around the entire periphery of the opening 54. Since the operating plate 52 closes the opening 54 in this manner, the load on the electric motor 55 increases rapidly, so the load current of the electric motor 55 increases rapidly. The change or magnitude of the load current is detected by the control circuit unit, and the rotation of the electric motor 55 is stopped.

Move. When the operation plate 53 opens the opening 54 to a predetermined position by the reverse rotation, the operation plate 52 collides with the stopper portion of the damper case 53 and stops. Due to this stop, the load of the electric motor 55 increases rapidly, and the load current of the electric motor 55 increases rapidly. The change or magnitude of the load current is detected by the control circuit unit, and the rotation of the electric motor 55 is stopped.

Further, the rotation stop control of the electric motor 55 may be a method in which the position of the operation plate 52 is detected and controlled by an optical switch or a mechanical switch. Further, a switch that detects a position where the operation plate 52 is closed or an open position may be provided, and the opening and closing of the operation plate 52 may be controlled by the number of pulse signals supplied from the detection position to the electric motor 55.

In the heat insulating partition wall 28, a passage wall constituting a part of the cold air supply passage 36 is formed with a quadrilateral flange 710 protruding inward, and the opening 550 is surrounded by the flange 710. ing. On the upper surface of the flange 710, a protrusion 720 protruding upward is formed in a quadrilateral shape that follows the quadrilateral flange 710.

なり大きい。 In addition, an elastic member 730 is attached to the lower surface of the operation plate 520 by adhesion. When the operation plate 520 is closed, a quadrangular protrusion 720 bites into the elastic member 730 so that the opening 550 is formed. It is a configuration that is blocked. In addition, the electric mechanism 510 of the damper device 500 has a configuration in which a DC motor and a plurality of reduction gear mechanisms are housed in a vertically long rectangular casing portion 540 formed integrally with one side of the damper case 530. . The housing portion 540 is disclosed in Patent Document 1 described above.
Is substantially similar to the casing described in JP-A-10-160322, and is considerably large.

る虞も考えられる。 In such a configuration, when the operating plate 520 closes the opening 550 by the electric mechanism 510, the quadrangular protrusion 720 bites into the elastic member 730, so that the operating plate 520 is opened in the use of the refrigerator for a long time. Sometimes this biting shape remains in the elastic member 730, and this gradually becomes a factor of reducing the sealing effect in this portion. This is the operating plate 5
In the system in which a switch for detecting the closed position or the open position of 20 is provided, and the opening and closing of the operation plate 520 is controlled by the number of pulse signals supplied from this detection position to the DC motor, control is performed to compensate for a decrease in the sealing effect. Adjustment such as changing the number of pulses is necessary, but this is difficult for the user of the refrigerator, and when a problem occurs in the temperature control, there is a possibility that it may be regarded as a failure of the refrigerator.

As a result, the structure of the portion in which the damper device 500 is incorporated into the refrigerator is limited, the flexibility of the refrigerator design is reduced, and the damper device 500 is incorporated into the refrigerator. The volume of the part increases, and the refrigerator compartment 3
There arises a problem that the effective use volume of the battery is reduced.

2 and the elastic member 73 of the operating plate 53 are pressed against each other when the operating plate 53 is closed, and the cold air passage is closed around the entire opening 54, so that a small-output motor 55 can be adopted and the size can be reduced. Even with the damper device 50 of the electric mechanism 51, the cool air can be sufficiently shut off in the damper device 50, and inaccurate temperature control in the refrigerator due to cold air leakage can be prevented. The elastic member 72 and the elastic member 73 can be made of a foam heat insulating material such as urethane synthetic resin in a relatively flexible state.

Flexibility is increased and it can be applied to refrigerators having various structures. In addition, the volume occupied by the damper device 50 in the refrigerator can be reduced by downsizing, and the article storage volume in the refrigerator can be increased as much as possible.
