Embodiment Construction

[0081] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0082] figure 1 It is a front external view of the refrigerator of this embodiment. figure 2 It represents the internal structure of the refrigerator figure 1 X-X longitudinal section view. image 3 It is a front view showing the internal structure of the refrigerator. Figure 4 Yes figure 2 An enlarged explanatory diagram of the main part of is a diagram showing the arrangement of the cold air duct and the air outlet. Such as figure 1 As shown, the refrigerator 1 of the present embodiment has a refrigerating compartment 2, an ice making compartment 3, an upper freezing compartment 4, a lower freezing compartment 5, and a vegetable compartment 6 in this order from the top to the bottom. As an example, the refrigerator compartment 2 and the vegetable compartment 6 are storage compartments in a refrigerating temperature zone with a temperature of about 3-5°C. In ...

Abstract

The present invention provides a damper device and refrigerator with damper device. The problem the invention object to resolve is that the switching body has elastic deformation due to the driving force (driving torque T) of the damper (the switching body) is closed, as the elastic deformation generate a gap partly between the switching body and the low abutting part arranged at the opening of the frame, The damper of the invention has: a frame (63) having a horizontal broad opening (62); a tabular switching body (64) of the switching opening (62); a driving mechanism (60) driving the switching body around the driving shaft in the length direction of the switching body; a first protuberance (81) provided near the driving shaft central of the switching body and extending in opposite direction of the driving shaft; and a second protuberance (82) provided on a frame on the opposite side of the opening relative to the driving shaft, when the switching body is closed, the first protuberance (81) is contacted to the second protuberance (82) so that the switching body is contacted to the opening edge.

Description

Technical field [0001] The present invention relates to a baffle device and a refrigerator with the baffle device. Background technique [0002] Conventionally, refrigerators have a storage room in a refrigerating temperature zone and a storage room in a freezing temperature zone, and the cold air, which has been heat-exchanged by the cooler, is sent to each storage room by an air blowing mechanism. In such a refrigerator of the so-called forced circulation of cold air, it is known to have an open-close type baffle device in order to control the flow of cold air delivered to each storage compartment, and to control the opening and closing of the baffle device. [0003] As the prior art related to the baffle device, the techniques described in Patent Document 1 (Japanese Patent Publication No. 2008-528923) and Patent Document 2 (Japanese Patent No. 3047160) are known. [0004] The structure disclosed in Patent Document 1 is as follows: A restriction is provided to mechanically restri...
