Centrifugal volute fan of ultra-thin air conditioner

Abstract

The invention discloses a centrifugal volute fan of an ultra-thin air conditioner. The centrifugal volute fan of the ultra-thin air conditioner comprises an air conditioner shell, volutes and centrifugal fans. Each volute is composed of an inner volute body, an outer volute body, an air outlet and a fixing chassis, wherein a filling cavity is formed between the inner volute body and the outer volute body; the inner volute body and the outer volute body are installed on the fixing chassis through sunk screws; and the air outlet is formed in the outermost end of the volute. Each centrifugal fan is composed of a drive motor and an impeller, wherein the drive motor is installed in the center of the corresponding fixing chassis through a screw, and the impeller is connected with a rotary shaft on the drive motor in a matched mode. The air conditioner shell is provided with an air inlet. By means of the centrifugal volute fan of the ultra-thin air conditioner, the problem that as an existing centrifugal volute fan of the ultra-thin air conditioner is large in size, an air conditioner body is large and noise is high is solved; and meanwhile, through air channels formed in the fixing chassis, the turbulent ratio of fluid is effectively reduced, and fluid output is better facilitated.

Description

technical field [0001] The invention relates to the related technical field of air conditioners, in particular to a centrifugal volute fan of an ultra-thin air conditioner. Background technique [0002] With the improvement of people's living standards, comfort and applicability have gradually become the primary conditions for people to choose air conditioners. Now there are relatively short floors, and the installation of air conditioners requires a relatively large hanging space, resulting in a smaller use space for residents. , so this kind of resident users need to choose an appropriate thinner air conditioner in combination with the use of the floor space; in addition, the built-in fan of the relatively thin air conditioner is due to the limitation of the air conditioner shell, resulting in insufficient pressure of the air fluid flowing out, resulting in output At the same time, the centrifugal fan used will cause relatively large noise. After the centrifugal fan is thi...

Problems solved by technology

[0002] With the improvement of people's living standards, comfort and applicability have gradually become the primary conditions for people to choose air conditioners. Now there are relatively short floors, and the installation of air conditioners needs to reserve a relatively large hanging space, resulting in a smaller use space for residents. , so this type of resident users need to choose an appropriate thinner air conditioner in combination with the use of the floor space; in addition, the built-in fan of the relatively thin air conditioner is due to the limitation of the air conditioner shell, resulting in insufficient pressure of the air fluid flowing out, resulting in output At the same time, the centrifugal fan used will cause relatively large noise. After the centrifugal fan is thinned due to the thinning of the shell of the air conditioner, the internal air fluid will be reduced due to the thinning of the space in the volute. It causes disorder, affects the working efficiency of the centrifugal fan, causes increased consumption and higher cost, and does not conform to the concept of green environmental protection and low-carbon energy saving
