Air conditioner outdoor unit with inclined centrifugal fan and air conditioner

Abstract

The invention discloses an air conditioner outdoor unit with an inclined centrifugal fan and an air conditioner and relates to the air conditioner technical field. The air-in and air-out directions of the air conditioner outdoor unit can be changed; the influence on outdoor environment is reduced; and air-in and air-out angles are made to be wider; the heat exchange performance of the air conditioner outdoor unit is improved. The problems of the big influence on the outdoor environment, the small air supply volume and the low efficiency of an air conditioner outdoor unit in the prior art are solved. The inclined centrifugal fan comprises an upper hub, a lower hub and vanes arranged between the upper hub and the lower hub. The tops of the vanes are connected with the upper hub, and the root portions of the vanes are connected with the lower hub. The edges, close to the circle centers of the upper hub and the lower hub, of the vanes are the air-in edges of the vanes, and the edges, far away from the circle centers of the upper hub and the lower hub, of the vanes are the air-out edges of the vanes. The side, close to the lower hub, of the inclined centrifugal fan is the air-in side; the side, close to the upper hub, of the inclined centrifugal fan and the outer sides of the air-out edges are air-out sides. The diameter of the lower hub is bigger than the diameter of the upper hub.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor air conditioner with an oblique centrifugal fan and an air conditioner. Background technique [0002] At present, the air conditioners sold on the market are mainly split-type air conditioners. The split-type air conditioners are divided into two parts: an indoor unit and an outdoor unit. The noisy components such as compressors and fans are placed in the outdoor unit. It has the advantages of beautiful appearance, many styles, small footprint, low indoor noise, convenient installation and maintenance, economical and practical. [0003] The fan is an important part of the outdoor unit of the air conditioner, which has an important impact on the performance of the outdoor unit of the air conditioner and the impact on the outdoor environment. [0004] In the prior art, the fan of the outdoor unit of the air conditioner generally adopts an axial flow fan, such a...

AI Technical Summary

Problems solved by technology

[0005] During installation, the air outlet of the outdoor unit of the air conditioner is generally set outward. If the installation height is low, it is easy to blow directly to people or other objects in the direction of the air outlet, which will affect the outdoor environment and cause uncoordinated living environment; Installed in the designated air conditioner installation places of the building. Decorative grilles are mostly used in these installation locations, and the decorative grilles will block the air outlet of the outdoor unit of the air conditioner, causing great wind resistance and reducing the air volume of the fan, which is not conducive to ventilation, making The performance of the air conditioner decreases, which in turn reduces the energy efficiency ratio of the air conditioner, making the user feel that the cooling and heating effect of the air conditioner is worse
