Air conditioner air outlet device

Abstract

The air conditioner air outlet device comprises a plurality of blades, a transmission mechanism, an air pipe barrel, a motor and a decoration ring, the air pipe barrel is of a hollow tubular structure and is provided with an inlet end and an outlet end, the blades are arranged in the air pipe barrel, and the roots of the blades are installed on a transmission shaft of the transmission mechanism; the decorative ring is arranged outside the air pipe barrel and connected with the outlet end, and the decorative ring is opened outwards in a splayed mode in the direction away from the air pipe barrel. During application, the motor drives at least part of the blades to rotate around the transmission shaft through the transmission mechanism, and the relative positions of at least part of the blades can be adjusted, so that the air supply distance can be changed and adjusted to adapt to different application sites, particularly meet the air supply requirement of a high and large space. Particularly, when the acute angle formed by the blade and the blade rotating plane is gradually reduced from the inlet end to the outlet end, the resistance coefficient of the air outlet can be reduced, and the energy consumption of the air conditioner is reduced; in addition, when the front edges of the blades are sawtooth-shaped, the vortex intensity can be weakened, and noise reduction is achieved.

Description

technical field [0001] The invention relates to the field of air-conditioning outlets, in particular to an air-conditioning outlet device. Background technique [0002] With the continuous development of China's economy, large-scale commercial buildings such as convention and exhibition centers, hotel lobbies, cinemas, shopping centers, etc., as well as large-scale public transportation buildings such as airports, high-speed railway stations, etc. have gradually increased. These buildings are characterized by high ceilings and internal structures. There are many kinds of people, and the flow of people is large. In order to achieve the demand for long-distance air supply in a large space, the air conditioning system generally adopts the air supply mode of swirl or jet according to the existing technology. The air outlet of such an air conditioning system mainly adopts a swirl air outlet or a jet air outlet. In practical applications, these two air outlets have some technical ...

AI Technical Summary

Problems solved by technology

The air conditioner outlets in the prior art are difficult to meet this design specification. Therefore, in order to ensure the fairness of the game, some arenas even directly shut down the air conditioner above the athletes during the game, causing indoor personnel, especially the athletes, to feel stuffy and uncomfortable. Low

[0005] Not only that, the existing air-conditioning air supply methods, such as simple swirling air outlets or jet nozzles, are difficult to accurately control the air supply speed at a given distance when applied to air-conditioning places with a floor height of 10 to 30 meters
