Vertical-type air conditioner air supply device with flow deflectors

Abstract

The invention discloses a vertical-type air conditioner air supply device with flow deflectors. The air supply device comprises an annular cover body, wherein a through air course is formed in the annular cover body, a mixed air outlet is formed at the front end of the through air course, an annular opening is formed on the wall of the annular cover body, the annular opening is provided with a plurality of annular flow deflectors for dividing the annular opening into a plurality of annular air outlets, the annular flow deflectors are obliquely arranged so as to enable the heat exchanging air inside an air course inside an air conditioner to be guided to the mixed air outlet from the annular air outlets, a minimal angle between each annular flow deflector and the axis of the annular cover body is greater than 0 degree, and a maximal angle is formed by overlapping an intersection point between an extension line of the tail end flow deflector and the axis of the annular cover body with an intersection point between the end surface of the mixed air outlet and the axis of the annular cover body. When the air supply device is used in the air conditioner, not only can the indoor air flow be accelerated and the outlet air softness of the air conditioner be improved, but also an appropriate air outlet direction can be obtained without the operation of a user, and the comfort experience effect of the user can be improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to a vertical air-conditioning air supply device, more specifically relates to a vertical air-conditioning air supply device with deflectors. Background technique [0002] The vertical air-conditioning duct structure in the existing market is generally all made up of air inlet, centrifugal fan, evaporator and air outlet. Indoor air enters the interior of the air conditioner from the air inlet, and after being centrifugally accelerated by the centrifugal fan, the air passes through the evaporator for heat exchange, and the air after heat exchange is blown into the room through the air outlet. [0003] At present, most of the air outlets are designed in a rectangular shape. A grill or fan blade is added to the air outlet to form an air supply device for the air conditioner. The grill or fan blade is used to balance the air volume at the air outlet and control the dire...

AI Technical Summary

Problems solved by technology

Such an air supply device can only send out the air after the heat exchange of the evaporator, and the air sent out is not soft enough, especially in the cooling mode, the cool air blown directly to the user, making the user feel uncomfortable

Moreover, the wind force blown out from the air outlet depends entirely on the air intake volume of the air conditioner and the power of the centrifugal fan. It cannot increase the air intake volume by itself, so it does not significantly enhance the flow of indoor air.

Moreover, the angle of the grille or fan blade at the air outlet of the existing air conditioner is controlled by the user, that is, the user needs to adjust the direction of the air outlet.

This method of adjusting the air outlet direction is not only cumbersome to operate, but also for the elderly, children and other users who do not understand the control method or are inconvenient to operate the remote control and control panel, it is easy to affect the experience of using the air conditioner due to the inability to adjust the air outlet direction
