Folding driving mechanism for air conditioner air intake grid

Abstract

The invention discloses a drive for opening / closing an air-intake grid of an air conditioner, which comprises a casing of the air conditioner, an air-intake grid that can open / close on the casing, and a drive to open / close the air-intake grid. The drive is a fully integrated gear rack drive that can make the air-intake grid open / close. The output part of the fully integrated gear rack drive, namely the rack, is connected with the air-intake grid. The structure of the drive comprises a main driving mechanism at one end of the casing of the air conditioner and a driven mechanism at another end of the casing of the air conditioner, and the main driving mechanism and the driven mechanism are respectively arranged in a left and a right half closed box. By a step motor and a pinion on the shaft of the motor, a bull gear is driven, a first gear that is coaxial with the bull gear drives a first rack at the left side. A second gear that is coaxial with the bull gear drives first driving gears at the two ends of a long shaft, and a second driving gear drives a second rack at the right side. The synchronous and same-directional movement of the first rack and the second rack realize the synchronous movement of the air-intake grid at left and right side, so that the grid will open when the air conditioner is on, and close when the air conditioner is off.

Description

technical field [0001] The invention relates to a split type air conditioner, in particular to an opening and closing driving device for an air intake grill of an air conditioner with an indoor unit. Background technique [0002] In the existing split-type air conditioner, the indoor unit is usually hung on the wall, and the air inlet grill is arranged on the casing. The air inlet grill of the air conditioner has two types, one is fixed, and the air inlet grill is installed There are several air intake grilles. The other is the overall flat type, which has no air intake grille on it. This form is determined by the appearance requirements. The air intake grille set on the front of the indoor unit is an integral flat type, compared with the fixed type. , not only is more beautiful, but also overcomes the unhygienic problem existing in the fixed upper air intake grille. Because the air enters through the gaps or openings of the fixed air intake grille, and the use of the air ...

AI Technical Summary

Problems solved by technology

Because the air enters through the gaps or openings of the fixed air intake grille, and the use of the air conditioner changes with the seasons. When not in use, dust will enter the interior of the air conditioner through the gaps, which is inconvenient to clean and wipe. It is not beautiful, these problems can be easily solved by the overall flat air intake grille
