Wall-mounted air conditioner indoor unit

Abstract

The invention relates to a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit comprises a shell, and at least one cross-flow fan and evaporators arranged in the shell. The shell is provided with an air inlet and a strip-type air outlet which blows air indoors, wherein two independent air guide plates are arranged at the air outlet; each air guide plate is configured to pivot around the extension direction, parallel to the air outlet, of the air guide plate in a controlled manner, and the rotary shafts of the two air guide plates are collinear or parallel; the evaporator is arranged on the at least one cross-flow fan in a covering manner and comprises a first heat exchange section, a second exchange section and a third heat exchange section which are successively connected from back to front. The third heat exchange section is a V-shaped heat exchange section, which extends obliquely, deviated from the outer side direction of the at least one cross-flow fan gradually toward the middle of the shell from two transverse ends of the shell or is a curved surface heat exchange section, which protrudes out of the shell and extends in a bent manner, deviated from the outer side direction of the at least one cross-flow fan gradually toward the middle of the shell from two transverse ends of the shell. Dual zone air blowing of multiple modes is achieved, the effective heat exchange area of the evaporator is increased, the heat exchange efficiency is improved, the air supplementing capacity is increased, and the operating noise is reduced.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a wall-mounted air conditioner indoor unit. Background technique [0002] In order to save space, household appliances such as air conditioners are increasingly miniaturized, but users have higher and higher requirements for air supply performance, cooling and heating performance, and aesthetic appearance. The traditional wall-mounted air conditioner indoor unit has a single appearance, and the limitation of shape change limits the improvement of air conditioner performance to a certain extent. [0003] The air conditioner indoor unit achieves the purpose of cooling or heating through the heat exchange between the evaporator and the air. Generally speaking, the larger the area of ​​the evaporator, the higher the efficiency of heat exchange. The traditional wall-mounted air conditioner indoor unit uses a cross-flow fan to drive air flow, and the evaporator is half-wrapped outside the cross-f...

AI Technical Summary

Problems solved by technology

However, a single axial flow fan or centrifugal fan cannot meet the normal air supply demand, and multiple axial flow fans or centrifugal fans need to be installed, and the axial flow fan has strict requirements on the position of the air inlet, and the air duct of the centrifugal fan The structure is relatively complex and takes up space, which leads to the structure of this type of wall-mounted air conditioner indoor unit is very complicated, the volume is relatively large, and the operating noise is relatively loud
