Description

Swing blade assembly for air conditioner and air conditioner with same

Technical Field

The invention relates to the technical field of air conditioners, in particular to a swing blade assembly for an air conditioner and the air conditioner with the same.

Background

Existing air conditioners or indoor units thereof (hereinafter, simply referred to as "air conditioners") disposed in a conditioned room are generally provided with an air intake opening and an air outlet opening. An air extracting or blowing device (such as a centrifugal fan or an axial flow fan) in the air conditioner sucks air in a conditioned room (which is generally called "return air") or fresh air outside the room into the air conditioner through an air inlet. The air is cooled or heated in the air conditioner by flowing over a heat exchanger arranged in the air conditioner. The cooled or heated air is then delivered into the room through the outlet. Accordingly, the intake vent is generally disposed at the top of the air-conditioning case, and the outtake vent is generally disposed at a lower portion of a front side (which may be referred to as a "front panel") of the air-conditioning case.

The air guide plate and the swing blade mechanism are usually arranged at the air outlet of the air conditioner to adjust the air outlet direction, so that the efficiency of the air conditioner for adjusting the temperature and humidity in a room is improved, and discomfort caused by directly blowing cooled or heated air to a user can be prevented. The air deflector can swing up and down under the driving of the driving mechanism so as to adjust the air outlet of the air outlet in the vertical direction; the swing blade mechanism generally includes a horizontal link and a plurality of swing blades fixed to the link at spaced intervals. The plurality of swing blades can be driven by the connecting rod to rotate left and right simultaneously, so that air outlet channels with different angles are limited, and air outlet in the horizontal direction of the air outlet is adjusted.

Due to the limitation of the shape and the space of the air outlet, the structure of the swing blade mechanism is complex, and the assembly efficiency of the swing blade mechanism is low. In order to solve the above technical problems, a wind swinging device has been developed in the prior art. For example, chinese utility model CN207065841U discloses a pendulum wind device, an air duct device and an air conditioner. The wind swinging device comprises a volute tongue component, a swinging blade component and a connecting rod. The volute tongue component comprises a volute tongue clamped on the framework shell, and at least one mounting groove is formed in the volute tongue; the swing blade assembly comprises a support and a plurality of blade assemblies fixedly arranged on the support, and the support is detachably fixed in the mounting groove; the connecting rod is provided with a plurality of clamping holes, and each blade assembly is detachably clamped in one clamping hole. This pendulum wind device realizes detachably assembly through the joint structure of snail tongue subassembly, pendulum leaf subassembly and connecting rod, and then promotes assembly efficiency. However, in the wind turbine generator, since the swing rib of the blade assembly is fixed to the bracket, the blade assembly needs to be twisted by 90 ° when being assembled to the link, and thus the blade is easily damaged. When the blade subassembly rotated under the drive of connecting rod, the blade also can twist reverse around the pendulum muscle, leads to there being mechanical fatigue in the blade, greatly reduced the life of blade subassembly. In addition, when one or more blades are damaged, the whole bracket must be replaced, and the service life of the wind swinging device is further influenced. Therefore, the wind swinging device has the possibility of improvement.

Accordingly, there is a need in the art for a new solution to the above problems.
