Abstract

An indoor air-conditioning unit, comprising a shell (1) and a heat exchanger (3) and a cross-flow fan (2) that are disposed in the shell (1). The cross-flow fan (2) comprises a cross-flow wind wheel (22) and a volute that are mutually matched. The volute comprises a top cover (21) and a volute tongue (23). A diffusion portion of the cross-flow fan (2) is formed between the top cover (21) and the volute tongue (23). The diffusion portion is downward and an air outlet is formed in a lower side surface of the shell (1). A rear side surface and / or an upper side surface of the shell (1) is provided with an air return port. An included angle λ of the connection lines of two end points of a molded line of the top cover (21) and the center of the cross-flow wind wheel (22) ranges from 185° to 225°.

Description

technical field [0001] The invention relates to the refrigeration field, 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. Due to the concealment of the concealed room air-conditioning unit, the concealed room air-conditioning unit often uses a partial ceiling method to save ceiling space; at the same time, the air-conditioning unit uses a side Back to the airflow circulation mode, the airflow can reach the middle and lower part of the room relatively easily. However, the noise problem of the existing hidden room air conditioners is more prominent when the air volume is increased, and the noise cannot be controlled within a reasonable range while further increasing the air volume. Contents of the invention [0003] In view of the status quo of the prior art, the purpose of the present invention is to provide an air conditioner i...
