wall mounted air conditioner indoor unit

Abstract

The invention provides an indoor unit of a wall-mounted air conditioner. The indoor unit of the wall-mounted air conditioner includes: a housing, which defines a cavity inside, and the housing includes a front panel, and the front panel is provided with an air inlet; the first air duct and the second air duct define a first outlet facing forward respectively The air outlet and the second air outlet; the evaporator is arranged inside the cavity corresponding to the air inlet, and is configured to exchange heat for the air entering the cavity through the air inlet; the laminar flow fan is arranged inside the cavity and behind the evaporator On the side, it is configured to use the viscous effect to make the air exchanged by the evaporator form a laminar flow, and blow out from the first air outlet through the first air channel and / or blow out from the second air outlet through the second air channel. The indoor unit of the wall-mounted air conditioner of the present invention realizes the up-and-down air outlet through only one laminar flow fan, which reduces the occupied area of ​​the laminar flow fan and the overall cost while reducing the loss of air volume; the laminar flow fan realizes laminar air supply through the viscous effect , the air supply process has low noise and high air volume.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an indoor unit of a wall-mounted air conditioner. Background technique [0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical equipment in people's daily life. Various air conditioning devices can help people reach an adaptable temperature when the ambient temperature is too high or too low. [0003] The current air conditioner control devices mainly include various types of air conditioners and fans. Since the indoor unit of the wall-mounted air conditioner is generally hung on the wall of the room and does not need to occupy the space at the bottom of the room, it is more and more widely used. However, the current indoor units of wall-mounted air conditioners mainly use cross-flow fans to supply air, and cross-flow fans often have the fol...

AI Technical Summary

Problems solved by technology

However, the current indoor units of wall-mounted air conditioners mainly use cross-flow fans to supply air, and cross-flow fans often have the following problems: the air outlet direction is directly in front, although there are swing leaves to guide the flow left and right, and the air deflector plate guides the flow up and down, but it is affected by Limited to the volute structure, the left and right air supply angle is less than 80°, and the up and down air supply angle is less than 100°, so the air supply range is very limited; due to the long strip air outlet, the air volume is concentrated and the wind speed is high, so the air output is very small. It is difficult to avoid people, resulting in a serious phenomenon of direct wind blowing people; the current cross-flow fans are mainly forward blades, the blades periodically impact the passing airflow, resulting in obvious rotating noise, and the volute cooperates with the cross-flow fan to achieve the air supply effect , the airflow will also be impacted at the front and rear volute tongues, resulting in strong turbulent noise. Under the limitation of performance indicators, the noise value is close to the limit
