Wall hanging machine with upper and lower air outlets and air outlet control method thereof and air conditioner

Abstract

The invention provides a wall hanging machine with upper and lower air outlets and an air outlet control method thereof and an air conditioner. The wall hanging machine comprises a shell (1), whereinthe shell (1) comprises an upper air port (11) which is located in the upper end of the shell (1) and a lower air port (12) which is located in the lower end of the shell (1), a first fan (21) is arranged in a position, which is close to the upper air port (11), in the shell (1), a second fan (22) is arranged in a position, which is close to the lower air port (12), in the shell (1), air can be sucked from the lower air port (12) by the second fan (22) when air is discharged from the upper air port (11) by the first fan (21), and air can be sucked from the upper air port (11) by the first fanwhen air is discharged from the lower air port (12) by the second fan. According to the wall hanging machine, different air ports can be used for discharging air and sucking air according to the actual demand, so that different requirements of users are met, the indoor comfort degree is increased, the air input can be increased, the heat exchange efficiency is improved, and quick cooling and heating are realized.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a wall-mounted machine with up and down air outlets, a method for controlling the air outlet, and an air conditioner. Background technique [0002] At present, most air-conditioning indoor wall-mounted units on the market use cross-flow fans. Since domestic wall-mounted units are mostly used in bedrooms with small spaces, and the characteristics of high-pressure airflow generated by cross-flow fan blades, it is easy to cause a hard wind feeling and a strong blowing feeling on the human body. . At the same time, the small flow rate of cross-flow fan blades will lead to low heat exchange efficiency. [0003] In the prior art, some wall-mounted air conditioners have used axial flow fans, but the existing wall-mounted air conditioners often have only one air outlet, and their air supply range and performance are limited, which cannot meet the various living need...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the fixed air outlet of the wall-mounted machine in the prior art, which makes it impossible to select different locations for air outlet according to the needs of the human body, resulting in poor cooling and heating effects in the room. As well as the small amount of air intake, the heat exchange efficiency cannot be further improved, and the comfort of the air conditioner is low, thereby providing a wall-mounted machine with upper and lower air outlets, an air outlet control method thereof, and an air conditioner
