Air quantity regulation mechanism, air channel device and refrigeration equipment

Abstract

The invention relates to an air quantity regulation mechanism, which comprises an air door, a gear and a driving lever. The air door is provided with an air door shaft and an air door blade installed at one end of the air door shaft; the gear is installed at the other end of the air door shaft; and the driving lever is provided with a rack which is meshed with the gear so as to convert the linear motion of the driving lever into the rotary motion of the gear. The air quantity is easy to control by the air quantity regulation mechanism of the invention, air quantity control and reasonable distribution can be realized and the air quantity regulation mechanism has reasonable appearance design and compact and beautiful appearance. The invention also relates to an air channel device with the air quantity regulation mechanism and a refrigerator with the air channel device.

Description

technical field [0001] The invention relates to the field of home appliance manufacturing, in particular to an air volume adjustment mechanism, an air duct device with the air volume adjustment mechanism, and a refrigeration device with the air duct device. Background technique [0002] In recent years, air-cooled refrigerators have gradually entered people's lives due to their advantages such as automatic defrosting, clean and dry, accurate temperature, and uniform cooling. Air cooling refers to such a cooling method, that is, a fan is used to blow the cold air generated by the evaporator into the storage room of the refrigerator to achieve the effect of cooling. A plurality of air outlets, thereby enabling cold wind to blow to various positions in the storage room of the refrigerator. [0003] The air-cooled refrigerator controls the temperature of the refrigerator's refrigerator or freezer by controlling the amount of air blown into the refrigerator or freezer. In the d...

Problems solved by technology

[0004] The control method of the push-pull damper is to open a part of the through hole on the push-pull lever, and the lever passes through the air duct. When the lever is adjusted, the through hole enters or leaves the air duct, thereby achieving the purpose of controlling the air volume, but the push-pull damper occupies The space is large, which is not conducive to the rational design of the product. At the same time, it also has the disadvantage of not being precise enough to control the air volume; the control method of the rotary damper is to open some through holes on the circumference of the rotary damper, and when the damper is rotated, the through holes enter or leave the air duct. To control the air volume, the rotary damper has a large protruding structure on the outside, which is not conducive to the smooth and beautiful surface of the product, and also has the disadvantage of not being precise enough to control the air volume
