Window air conditioner

Abstract

The invention discloses a window air conditioner which comprises an indoor panel, a case, an evaporator, an indoor fan, a condenser, an outdoor fan, a compressor and a chassis, wherein a noise filtering device is arranged at the exhaust port of the air conditioner, and comprises an exhaust plate and a choke plate; multiple round vent holes are arranged on the exhaust plate in order, and the choke plate is arranged at the inner side of the exhaust plate; the choke plate is formed by mutually connecting multiple round choke pieces the diameters of which are larger than those of the round vent holes on the exhaust plate, and the positions of the choke pieces are in one-to-one correspondence with the positions of the vent holes; and the included angle of the choke plate and the exhaust plate is adjustable, i.e. the included angle of each choke piece and the air-out direction of the corresponding vent hole can be changed at the same time, thus the flow characteristic of air which is discharged along the indoor direction is changed, thereby changing the sound quality of the noise formed when the air rubs with the exhaust plate. Users can set the open angles of the choke pieces according to the judgment on the noise, so that products can obtain sound characteristics adaptive to different requirements of the users.

Description

technical field [0001] The present invention relates to the technical field of window-type air conditioners, in particular to an air outlet equipped with an exhaust plate and a choke plate, by changing the angle between each choke plate on the choke plate , so as to improve the sound quality of the wind from the outside part of the window air conditioner. Background technique [0002] Generally, an air conditioner is a device that cools or heats an indoor environment to create a comfortable indoor environment, and is roughly classified into an integrated type air conditioner and a split type air conditioner. [0003] Although the integrated air conditioner and the split air conditioner have the same function, the integrated air conditioner is equipped with cooling and heat dissipation components in the same casing, and is installed on the wall or on the window through the wall. The window air conditioner is the most common. The integrated air conditioner, while the split ty...

Problems solved by technology

[0007] In the window-type air conditioner of the above prior art, when the indoor fan is running, the air flowing through the evaporator is discharged to the room through the exhaust port. Due to the fast air flow speed, friction occurs between the air and the exhaust port to generate noise, and the wind speed The faster the noise, the more obvious the noise, and due to the physical differences of the users, each person's ears have different judgment abilities and standards for noise, resulting in the same exhaust sound having different feelings to different people, and some people sound relatively The calm sound may be very noisy compared to others, so it is difficult to set a fixed exhaust vent to meet the noise requirements of each user
