Abstract

The invention discloses an indoor unit of an air conditioner. The indoor unit of the air conditioner comprises a shell, a heat exchanger and a cross-flow fan, the heat exchanger and the cross-flow fan are mounted in the shell, and the cross-flow fan comprises a cross-flow wind wheel and a volute which are matched with each other; the volute comprises a front volute tongue which is formed into the first lateral surface of a diffusion part of the cross-flow fan and a rear volute which is formed into the second lateral surface of the diffusion part, wherein the second lateral surface is opposite to the first lateral surface, the diffusion part is downward, an air outlet is formed in the lower lateral surface of the shell, and a return air inlet is formed in each of the rear lateral surface and / or upper lateral surface of the shell; the first lateral surface is a curved surface which bends towards the heat exchanger, a bus of the first lateral surface comprises at least two segments, and each segment is a straight line or a curved line. According to the indoor unit of the air conditioner, the air outlet is formed in the lower lateral surface, the return air inlet is formed in each of the rear lateral surface and / or upper lateral surface, so that a room can be partially ceiled, and air currents are easier to arrive at the middle and lower parts of the room to improve the air flow circulation of the whole room. The front volute tongue is optimized to enable the first lateral surface to form in curved surface mode, and accordingly the machine set noise is lowered.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner indoor unit. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the decoration of the room, and the concealed room air-conditioning unit is gradually welcomed by people because of its concealment advantages. At present, there are mainly two types of air inlet and outlet types of hidden air conditioner indoor units with one-way air outlet on the market. The first type is the bottom-inlet and side-outlet concealed air-conditioner indoor unit, that is, the return air outlet 11 is set on the lower bottom surface of the air-conditioner indoor unit. The air outlet 12 is arranged on the rear side of the air conditioner indoor unit. figure 1 This is a schematic diagram of the airflow cross-section of the bottom-in and side-out concealed air conditioner indoor unit after installation. The bottom-in and ...
