Wall-mounted air conditioner indoor unit

Abstract

The invention discloses a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit comprises a shell, a cross-flow fan and an evaporator; the shell is provided with an air inlet and an air outlet, and an air guide plate which is used for adjusting the opening and closing states and / or the air outlet direction of the air outlet is formed in the air outlet; the cross-flow fan and the evaporator are arranged in the machine shell; the evaporator is arranged on the cross-flow fan in a covered mode, and comprises a first heat exchange section, a second heat exchange section and a third heat exchange section which are sequentially connected with one another from the back to the front, and the third heat exchange section is located on the front side of the cross-flowfan; and the third heat exchange section is a V-shaped heat exchange section which is gradually inclined forwards and extends from the transverse two ends of the machine shell to the middle of the machine shell so as to form a triangular space between the third heat exchange section and the cross-flow fan, or, the third heat exchange section is a curved surface heat exchange section which gradually protrudes, is curved and extends from the transverse two ends of the machine shell to the middle of the machine shell so as to form an arch space between the third heat exchange section and the cross-flow fan. According to the wall-mounted air conditioner indoor unit, the effective heat exchange area of an evaporator is expanded, the heat exchange efficiency is improved, the air supplement amount is increased, and the operation 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. [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-flow fan. It is generally believed in the prior art that the area of ​​the evaporator of such an indoor unit using a cross-flow fan is not large enough, and the heat exchange efficiency is not ...

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
