air conditioner indoor unit

Abstract

The invention provides an air conditioner indoor unit. The air conditioner indoor unit comprises a shell, a centrifugal fan, a heat exchanger and a draining air guiding device, wherein the shell is provided with a first air inlet, a second air inlet and an air outlet; the first air inlet is formed in the upper portion of the shell; the air outlet and the second air inlet are formed in the front side and the rear side of the lower portion of the shell respectively; the centrifugal fan is arranged in a containing space inside the shell and arranged to suck environmental air from the environment around the first air inlet and urge the air to flow to the lower portion of the shell; the heat exchanger is arranged on an air inlet channel between the centrifugal fan and the first air inlet in the shell; the draining air guiding device is arranged on the lower portion of the containing space inside the shell and arranged to mix airflow from the centrifugal fan and airflow from the second air inlet and blow out the mixed airflow through the air outlet. A middle air guiding ring of the draining air guiding device is formed in a mode that the connecting line of the circle center of the projection line of the rounded top contour of the middle air guiding ring and the midpoint of the projection line of the front end edge of the middle air guiding ring forms a first included angle with the projection line of the front end edge of the middle air guiding ring. The air conditioner indoor unit is capable of increasing the air supplying amount of an air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner indoor unit. Background technique [0002] The indoor units of the existing wall-mounted air conditioners are all strip-shaped, and use a cross-flow fan and a bent evaporator for air supply. The air after heat exchange of the bent evaporator is directly blown out from the air outlet under the action of the internal cross-flow fan, and all the air blown out is heat exchange air. One disadvantage of this kind of air supply is that the air sent out is all heat exchange air, the air volume is small, and the indoor air circulation speed is slow; another disadvantage is that the air sent out is not soft enough, especially in the cooling mode, the cool air blown out The wind blows directly on the user, and the user feels uncomfortable. [0003] In addition, because the indoor units of the existing wall-mounted air conditioners are elongated, they are not on...

Problems solved by technology

One disadvantage of this kind of air supply is that the air sent out is all heat exchange air, the air volume is small, and the indoor air circulation speed is slow; another disadvantage is that the air sent out is not soft enough, especially in the cooling mode, the cool air blown out The wind blows directly on the user, and the user feels uncomfortable

[0003] In addition, because the indoor units of the existing wall-mounted air conditioners are long strips, they are not only bulky and occupy a large installation space, but also not beautiful enough to meet the diverse needs of the market.
