Abstract

The invention discloses a centrifugal fan volute. The centrifugal fan volute is arranged in a shell of an indoor machine; an air inlet and an air outlet are formed in the shell; a heat exchanger is arranged in the shell and between the volute and the air outlet; an air outlet extending structure is arranged at the air outlet position of the volute; and the air outlet extending structure is positioned on an extended line of a volute shaped line. According to the centrifugal fan volute and the indoor machine, provided by the invention, reflux area is small, fan efficiency is high and noise is low; and the fact that wind can blow to an effective area of the heat exchanger accurately is guaranteed, dispersion of the wind is reduced and the heat exchange efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention belongs to the technical field of volutes, and in particular relates to a centrifugal fan volute and an indoor unit designed using the volute. Background technique [0002] With the design of the traditional centrifugal fan volute, the air flow from the volute outlet is relatively large, resulting in a decrease in the air volume blown to the heat exchanger and reducing the heat exchange efficiency of the heat exchanger. Contents of the invention [0003] The invention provides a centrifugal fan volute, which reduces the dispersion of wind. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions to achieve: [0005] A centrifugal fan volute, installed in the casing of the indoor unit, an air inlet and an air outlet are arranged on the casing, a heat exchanger is arranged in the casing, between the volute and the air outlet, and the volute The air outlet is provid...
