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, a drainage air guide device, a baffle plate and a horizontal moving mechanism, wherein the shell is provided with a first air inlet, a second air inlet and an air outlet; the centrifugal fan is arranged in the shell, and the rotary axis or the extension line of the rotating axis of the centrifugal fan passes through the first air inlet; at least part of a heat exchange section of the heat exchanger is in a flat plate shape, and the heat exchanger is located between the centrifugal fan and the first air inlet; the drainage air guide device is arranged in the shell and used for guiding airflow from the centrifugal fan and airflow from the second air inlet into the drainage air guide device to be mixed, and the mixed airflow is blown out of the air outlet in a velocity component mode in the direction parallel to the rotating axis of the centrifugal fan; the horizontal moving mechanism is used for driving the baffle plate to move in the direction parallel to the rotating axis of the centrifugal fan so as to open or close the first air inlet. The air conditioner indoor unit is large in air supply volume and capable of blowing out gentle mixed air with a moderate temperature.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular to an air conditioning 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 indoor unit of the wall-mounted air conditioner is not only prone to appearance visual aesthetic fatigue, but also the wind after heat exchange of the bending evaporator is directly blown out from the air outlet under the action of the internal cross-flow fan, and all the blown air 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.

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.
