Problems solved by technology

[0003] 1. The purpose of the present invention is to provide an air-conditioning indoor unit, which solves the problems of the existing air-conditioning indoor units that the wind is not soft enough and the air supply volume is small, that is, fully achieves the purpose of the D patent invention, and solves the problems caused by the D patent. Poor air induction effect of wind components and additional air inlets bring serious backflow problems

Abstract

The invention discloses an indoor unit of an air conditioner. The indoor unit comprises an air outlet air flue of a through-flow impeller, and an air outlet air flue wall of the through-flow impeller, wherein an air opening is formed in the air outlet air flue wall of the through-flow impeller; the upper side end and the lower side end of the air opening are perpendicular to a shaft axis of the through-flow impeller of the indoor unit; an air outlet of the indoor unit is positioned in a projection plane at the left lower side; and a clockwise included angle between a connecting line from the upper side end to the lower side end and a tangent line positive direction section of the air outlet air flue wall which takes the upper side end as a point of tangency is greater than or equal to 10 degrees but smaller than or equal to 200 degrees. The indoor unit has the advantages that air quantity of outlet air is great and outlet air is mixed air, which is cool but not cold, formed by exchange air and indoor air.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and only relates to an air conditioning indoor unit. Background technique [0002] When the existing air-conditioning indoor unit is working, the indoor air is sucked into the indoor unit under the action of the cross-flow impeller, becomes heat-exchanged air after exchanging heat with the heat exchanger, and is blown out by the air outlet duct of the indoor unit. The air outlet air duct of the existing air conditioner indoor unit is a closed air duct, and the heat exchange air is isolated from the indoor air outside the air outlet air duct before being blown out. Therefore, all the air outlet air duct blows out is heat exchange. wind. Especially in the cooling mode, the temperature difference between the air inlet and outlet of the indoor unit of the air conditioner reaches about 14 degrees, which is a large temperature difference compared with the original indoor air temperature. When...
