Wind-guiding structure for wall type air-conditioner indoor set

Abstract

The invention relates to an air guide structure for indoor unit of wall-mounted air-conditioner , comprising a motor (1) and a plurality of shutters (7); wherein, an output shaft of the motor (1) is connected with a connecting rod (2) of the motor. The both ends of the motor connecting rod (2) are connected with the connecting rod of the front shutter (A) and the connecting rod of the back shutter (B), respectively. A plurality of shutters (7) are connected with the connecting rod of the front shutter (A) and the connecting rod of the back shutter (B) by rotating shafts, respectively. The connecting rods of the front shutter (A) are composed of a right-front shutter connecting nod (4) and a left-front connecting nod (6); the connecting rods of the back shutter (B) are composed of a right-back shutter connecting nod (5) and a left-back shutter connecting nod (8). The left-front connecting nod (6) and the left-back shutter connecting nod (8) are connected with the right-front shutter connecting nod (4) and the right-back shutter connecting nod (5), respectively. A plurality of shutters (7) are connected with the left-front connecting nod (6), the left-back shutter connecting nod (8), the right-front shutter connecting nod (4) and theright-back shutter connecting nod (5) by rotating shafts, respectively, and are connected into two groups. The invention has the advantages of simple manufacture technology, quick-assembly, reliable performance and low maintenance costs, even left-right adjustment of air flow in horizontal direction of air conditioner.

Description

Technical field: [0001] The invention relates to an air guide structure for a wall-mounted air conditioner indoor unit, which belongs to the transformation technology of the air guide structure used in the wall-mounted air conditioner indoor unit. Background technique: [0002] In the existing split wall-mounted air conditioner indoor unit, the airflow in the horizontal direction is adjusted by driving the louvers to swing left and right. The split wall-mounted air conditioner indoor units currently on the market can be roughly divided into manual drive and automatic drive according to the drive mode of the louvers, and the automatic drive is completed by the drive of a stepping motor or a synchronous motor. [0003] In the prior art, the air guide structure for adjusting the horizontal direction can be roughly divided into the following five forms: the first form is to design the lower plate on which the louvers are installed and the main body of the air outlet frame, and t...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the air guide structure for adjusting the horizontal direction can be roughly divided into the following five forms: the first form is to design the lower plate on which the louvers are installed and the main body of the air outlet frame, and the louvers are directly installed on the On the air outlet frame, this form increases the difficulty and cost of mold manufacturing for the air outlet frame due to the integrated design of the lower plate where the louvers are installed and the main body of the air outlet frame. Rod) is more inconvenient and increases maintenance costs

Since the louvers are directly installed on the lower plate of the air outlet frame, it is extremely inconvenient to assemble the louvers

The second form is to divide the louvers into two groups, and each group is connected by a connecting rod and driven by a stepping motor. In this form, when the air conditioner is running, the running directions of the two groups are opposite, and they often occur at the same time. The phenomenon of blowing air to both sides or the middle separately; when blowing air to both sides separately, a dead zone of air supply is formed in the middle; when blowing air to the middle separately, the air supply is too concentrated and the air supply range is small

The third main problem is that when the louvers are blowing air, the jitter is relatively large

The third form is to divide the louvers into ordinary louvers and driven louvers. Each louver has two rotating shafts. The louvers are divided into two groups, left and right. The louvers are connected to the lower plate of the air outlet frame through the large rotating shafts of the louvers. The small rotating shafts of the two groups of louvers are respectively connected by the left and right connecting rods, and the left and right connecting rods are connected by buckles, and the louvers are driven by a stepping motor to realize the synchronous movement of the left and right groups of louvers. The main defect of this form Because when the louvers are blowing air, the jitter is relatively large

The fourth form is as described in the patent document (ZL 200520017206.1), connecting all the wind guide vanes with a connecting rod and controlled by a motor. Due to the large stroke and resistance torque of the stepping motor, this form is not suitable for long-term use. In the running mode, the probability of damage is too high

The fifth form is to design the louver and the air outlet frame as a whole. Due to the softness of the louver itself, the angle change is achieved by pulling the motor. The main defect of this form is that the mold is quite complicated and the motor resistance torque is too large
