A wall-mounted air conditioner indoor unit and air conditioner

technical field

The invention relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner indoor unit and an air conditioner.

Background technique

At present, among various types of air conditioners, the wall-mounted air conditioner has been widely used because it is not restricted by the installation location and is easy to match with interior decoration. The existing wall-mounted air conditioners generally include indoor The indoor unit of the wall-mounted air conditioner usually includes a casing and a cross-flow fan and an evaporator in the casing. The upper surface of the casing is provided with an air inlet, and the front surface of the casing is provided with an air outlet. The rear surface of the casing is used to be attached to the wall and fixedly connected. During operation, the external air enters the casing from the air inlet under the action of the cross-flow fan, flows through the evaporator and the cross-flow fan in turn, and is sent out from the air outlet.

In the prior art, the airflow enters the impeller of the crossflow fan along the axial direction perpendicular to the crossflow fan, and passes through the impeller twice. The impeller acts on the airflow twice, and inside the impeller, the airflow is forced to bend, so that the airflow The pressure loss is relatively large, and the air volume is low. At the same time, the static pressure of the air duct system in the air-conditioning indoor unit of the existing cross-flow fan is low, and the resistance performance is poor, so that the heat exchange efficiency of the evaporator is low. At the same time, due to The upper surface of the existing casing is relatively small, so that the size of the air inlet is small, which is not conducive to increasing the air volume. If the air volume is too small, the heat exchange efficiency will be too low and the user's comfort level will be reduced.
