Problems solved by technology

[0017] However, first, there is the following problem in the existing structure shown in above-mentioned Fig. 18~Fig. In the state, it is also in the state of applying load to each gear. In addition, when the rotation angle of the motor 108 deviates due to control fluctuations or noise, etc., the flapper 104 cannot be completely closed, and the flexible belt 105 and the opening There will be a gap between the protrusions 103 of 102, and as a result, cold air will leak, or the baffle 104 will not be fully opened, and enough cold air will not flow into the refrigerator compartment, and reliable opening and closing operations will not be performed.
[0018] In addition, there is the following problem in the above-mentioned conventional structure: the driving part 106 needs the casing 107, the pinion 109, the reduction gear set 110 composed of three gears, the driving gear 111, the driven gear 113, etc., and the number of parts is large, making it difficult to Further miniaturization requires additional time for assembly, etc.
[0020] Second, in the conventional structures shown in FIGS. 18 to 21, the frame 101 has an opening forming portion 101a and a protruding portion 103 at one end of the side wall 101b, and the cross-section has an angular U-shape. Therefore, when resin molding The cooling balance is poor, and the cooling is slow compared with the side that does not have the opening forming portion 101a and the protruding portion 103. Due to the delay in cooling, the frame 101 as a whole has a structure that is easy to bend as shown by the dotted line (see FIG. 20 ).
In this case, there is a problem that poor contact may occur due to floating or falling off of the mating connector, which may hinder the operation of the damper device.

Abstract

The invention provides an adjustable damper device with reliable action, high reliability, simple structure, good assembleability and low cost. For this reason, the driving part (4) includes: a casing (12) forming an outer shape; a motor (13) as a drive source capable of forward and reverse rotation; a drive gear (15) that transmits the rotation of the motor (13); The gear (15) is a driven gear (16) for driven rotation, and the driving gear (15) includes: meshing with the driven gear (16) only when opening and closing, and meshing with the driven gear (16) when opening and closing. ) is disengaged, whereby the gear part (15b) meshes with the driven gear (16) only for a specified period; and the holding part (15c) that holds the position of the driven gear (16) when it is opened and closed .

Description

technical field [0001] The present invention relates to a damper device for opening and closing an opening with a damper, and more particularly to a damper device for controlling temperature by opening and closing a cold air passage in a storage room such as a refrigerator. Background technique [0002] Conventionally, as a unit for controlling the temperature of a plurality of refrigerated compartments in a refrigerator, a damper is used to open and close the air passage of cold air from the cooler to each refrigerated compartment, thereby controlling the temperature of the cold air flowing into each refrigerated compartment. These damper devices are roughly classified into a system in which one damper is operated by one driving source and a system in which two dampers are operated by one driving source. [0003] In the method of operating one damper with one driving source, the rotation control of a motor is used to open and close one opening. As a representative damper de...
