Indoor unit of air conditioner

Abstract

The invention provides an indoor unit of an air conditioner. The indoor unit of the air conditioner comprises a case, an air supply assembly, a first air guide component, a second air guide componentand an indoor heat exchanger. The case is provided with a heat exchange air inlet, a natural air inlet, a first air outlet and a second air outlet. The air supply assembly comprises a shell with a volute formed, an impeller arranged in the volute, a motor in drive connection with the impeller and a motor support used for fixing the motor to the volute. At least one annular air outlet extending inthe front-and-back direction is formed by the first air guide component, the annular air outlets are configured to blow air flow forwards so as to promote environment air surrounding the natural air inlet to flow forwards to be mixed with heat exchange air blown out by the annular air outlets. The air supply assembly further comprises a drive device used for driving the shell to rotate and enabling an air outlet of the volute to be in butt joint with an air inlet of the first air guide component or the second air guide component. Flexibility is high, indoor temperature can be uniform rapidly,and the production cost is low.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning indoor unit. Background technique [0002] In the prior art, the cabinet-type air-conditioning indoor unit with a single air outlet usually sets the air outlet on the top of the cabinet, and there is a problem that the hot air flows upward during heating, and the indoor temperature is uneven; the cabinet-type air conditioner with multiple air outlets indoors Each air outlet corresponds to an independent air supply fan. By controlling the start and stop of multiple air supply fans separately, the indoor temperature can be quickly and uniformly achieved. However, it also brings high production costs. When the upper and lower asynchronous air supply The problem of low heat exchange efficiency of the heat exchanger. Considering comprehensively, an air conditioner indoor unit with uniform cooling / heating and low production cost is required in design. Contents of ...
