Problems solved by technology

[0003] The purpose of the present invention is to provide a mixed air-conditioning indoor unit to solve the problems of the existing air-conditioning indoor unit that the air is not soft enough, the temperature difference between the air and the indoor air is large, the human body feels uncomfortable, and it is easy to get "air-conditioning disease". At the same time, the invention also has the functions of accelerating the indoor air conditioning cycle, reducing the time required to reach the set temperature, and saving time and electricity.

Abstract

The invention discloses a hybrid air conditioner indoor unit, which comprises an indoor unit casing, a cross-flow impeller air outlet duct, and a cross-flow impeller air outlet duct wall, and is characterized in that: the cross-flow impeller air outlet duct wall is set There is an air inlet, the air inlet is perpendicular to the axis line of the cross-flow impeller of the indoor unit, and the projection line on the projection plane where the air outlet of the indoor unit is located on the lower left side, the point where it intersects with the wall of the air outlet duct is the upper tangent point of the outlet air The clockwise included angle of the positive direction section of the tangent line of the channel wall is greater than or equal to 12° to less than or equal to 198°, and an induction fan is installed on the outside of the air outlet wall of the cross-flow impeller, and the air outlet of the induction fan is connected to the induction air duct. The air outlet communicates with the air induction opening provided on the wall of the air outlet duct of the cross-flow impeller. The invention has the advantages of large air volume and speed, long shooting range, and the heat exchange air and indoor air form cool but not cold mixed 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, exchanges heat with the heat exchanger to become heat-exchanged air, and is discharged from the air outlet duct of the indoor unit. Existing air-conditioning indoor unit outlet air duct is closed type, and the heat exchange air is isolated from the indoor air outside the air outlet duct before being discharged. Therefore, all the air outlet air duct discharges is heat exchange air, In the cooling mode, the temperature difference between the air inlet and outlet of the air conditioner indoor unit reaches about 16 degrees, which is a large temperature difference compared with the original indoor air temperature. When the air conditioner reaches the set temperat...
