Indoor unit of wall-mounted air conditioner

Abstract

The invention provides an indoor unit of a wall-mounted air conditioner. The indoor unit of the wall-mounted air conditioner comprises a shell, an evaporator and two laminar flow fans, wherein a cavity is defined in the shell, the shell comprises a front panel and a rear shell, the rear shell is provided with an air inlet, and the front panel is defined with two air outlets; the evaporator is arranged at the position, corresponding to the air inlet, inside the cavity and is configured to exchange heat with air entering the cavity through the air inlet, the evaporator is provided with a peripheral wall and a bottom wall, the bottom wall is parallel to the front panel, and the peripheral wall is positioned on one side close to the front panel; and the two laminar flow fans are arranged on the front side of the evaporator and are configured to enable air subjected to heat exchange of the evaporator to form laminar flow air by utilizing a viscosity effect and enable the laminar flow air tobe blown out from the air outlets. According to the indoor unit of the wall-mounted air conditioner, laminar air supply is realized through the viscosity effect, the noise is low, and the air quantity is high; the two laminar flow fans can respectively and independently control air supply; and the cover buckle type evaporator greatly increases the heat exchange area and effectively improves the overall working efficiency of the indoor unit of the wall-mounted air conditioner.

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
