Wall-mounted air conditioner indoor unit and air conditioner

Abstract

The invention provides a wall-mounted air conditioner indoor unit and an air conditioner and relates to the technical field of air conditioners. According to the wall-mounted air conditioner indoor unit and the air conditioner, the air amount can be increased and the heat exchange efficiency can be improved. The wall-mounted air conditioner indoor unit comprises a machine shell and an evaporator arranged in the machine shell. Air inlets and air outlets are formed in the machine shell. The wall-mounted air conditioner indoor unit further comprises an axial fan. The axial fan is located in the machine shell. The machine shell comprises a front surface and a rear surface. The air outlets are formed in the front surface. The air inlets are formed in the rear surface. The machine shell is further provided with an installation base. The installation base is used for being fixedly connected with a wall. After the installation base is fixedly connected with the wall, gaps are formed between the air inlets and the wall. The wall-mounted air conditioner indoor unit provided by the invention is used for the air conditioner.

Description

technical field [0001] 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 [0002] 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...

AI Technical Summary

Problems solved by technology

[0003] 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 small, so 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 comfort of the user will be reduced.
