Problems solved by technology

[0003] With the improvement of people's quality of life, the requirements for air conditioners closely related to daily life are getting higher and higher. Noise and sound quality are an important indicator of wall-mounted air conditioners. There is a phenomenon of uneven air outlet, and there will be discontinuous air outlet noise, that is, there will be vibration

Embodiment Construction

[0016] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0017] Such as figure 1 and figure 2 shown. The low-noise wall-mounted air conditioner of the present invention includes an air outlet 1 and a bottom case 2. A baffle 3 is installed on both sides of the air outlet 1 in the axial direction, and the baffle 3 is fixed on the bottom case 2. The baffle plate 3 can effectively prevent the hot air outside the air conditioner from recirculating, and avoid wind noise caused by uneven air outlet.

[0018] The baffle plate 3 is provided with four ventilation holes 4, the ventilation holes 4 are arranged longitudinally, and are preferably located in the middle of the baffle plate 3, and the cold wind can pass through the ventilation holes 4 to reduce the temperature difference between the two sides of the baffle plate 3, thereby reducing Condensation.

[0019] Preferably, the baffle 3 has a length of 20-50 mm, a widt...

Abstract

The invention discloses a low-noise wall-mounted air conditioner which comprises an air outlet and a bottom shell, wherein baffle plates are arranged on two sides of the air outlet in the axial direction; and the baffle plates are fixed to the bottom shell and can prevent hot air outside the wall-mounted air conditioner from being returned, therefore, a phenomenon of non-uniform air exhaust caused by hot air return is avoided, thus the noise of the air conditioner is reduced.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to a low-noise wall-mounted air conditioner capable of reducing the noise caused by the vibration phenomenon. Background technique [0002] The left half of the performance curve of the axial flow fan has a saddle-shaped area. Sometimes there will be large fluctuations in the flow rate, pressure head and power of the fan when operating in this area, and the fan and pipeline will produce strong vibrations, and the noise will increase significantly. Abnormal working conditions are generally called "surge", and this unstable working condition area is called the surge area. In fact, surge is only a phenomenon that may be encountered in the unstable working condition area, and what must appear in this area is the phenomenon of rotating shedding or rotating stall. These two working conditions are different, but they have a certain relationship. [0003] With the improvement o...
