Damper Apparatus and Refrigerator having the same

Abstract

The invention relates to a damper apparatus and a refrigerator having the same. The invention aims to conduct temperature control of high reliability through reliably closing the opening of an electric damper and obtain a refrigerator with high energy-saving performance. The refrigerator comprises a chilling temperature zone chamber disposed on a refrigerator body, a cooler chamber which is disposed behind the chilling temperature zone chamber and is provided with a cooler, a blower which transports cooling air from the cooler chamber to the chilling temperature zone chamber, a separating plate which separates the cooler chamber and the chilling temperature zone chamber, and makes the cooling air transported by the blower blow out from the blowout mouth of the chilling temperature zone chamber, and a chilling chamber damper which controls the air output to the chilling temperature zone chamber. The chilling chamber damper comprises a frame communicating the cooler chamber and the opening of the blowout mouth, an opening/closing body used for opening or closing the opening, and a drive mechanism driving the opening/closing body. The opening of the chilling chamber damper is larger than the blowout mouth in area.

Description

technical field [0001] The present invention relates to a baffle device and a refrigerator provided with the baffle device. Background technique [0002] In a refrigerator of the cold air forced circulation method that uses a common cooler to cool the refrigerator and freezer, the temperature of the refrigerator is controlled at approximately 3 to 5°C, and the temperature of the freezer is controlled at approximately -18°C. The temperature zone is different. Therefore, when distributing cold air from the cooling room to each of the refrigerator room and the freezer room through the cold air passage, it is necessary to switch the flow rate of the cold air. [0003] As conventional technologies related to an electric damper as a mechanism for switching the flow rate of cold air, the technologies of Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-180719 ) and Patent Document 2 (Japanese Patent Laid-Open No. 2002-31466 ) are known. [0004] Patent Document 1 ...

AI Technical Summary

Problems solved by technology

However, if the opening area of ​​the baffle device is enlarged, each part becomes larger, so there is a problem that the rigidity of the parts is lowered, elastic deformation is easy, and a gap is likely to be generated during locking, making it difficult to seal.

[0012] In Patent Document 1 and Patent Document 2, there is no description of the size relationship between the opening area of ​​the baffle plate for the freezer and the air outlet leading to the freezer.

In addition, there is no description on the closure of the partition as the opening and closing body and the appropriate aspect ratio of the partition shape.

In other words, there is no description of the ideal size relationship between the opening of the partition and the blowing nozzle and fan size of the freezer, or the appropriate ratio of the vertical and horizontal dimensions of the partition.
