Embodiment Construction

[0024] see figure 1 , figure 2 , image 3 and Figure 4 A groove 3 is provided on the base 7 of the indoor unit, where the base 7 of the indoor unit is located in the air duct of the cross-flow fan 4 and is located below the side of the cross-flow fan 4 . The shape of the indoor unit base 7 here is a concave arc-shaped plate. A cleaning brush 1 is installed in the groove 3 , and the length, width and thickness of the groove 3 are adapted to the length, width and thickness of the cleaning brush 1 . When not cleaning, the cleaning brush 1 is retracted in the groove 3 . Depend on figure 2 It can be seen that the cleaning brush 1 is a row-type cleaning brush, and the length of the cleaning brush 1 matches the length of the fan 4 . This can clean the cross-flow fan 4 as a whole. The cleaning brush driving motor 8 that drives the cleaning brush 1 to rotate is connected with the cleaning brush shaft hole 6 of the cleaning brush 1 through the motor shaft. The driving motor 8...

Abstract

The invention provides an air conditioner which has the function of automatically cleaning an indoor unit fan and is capable of solving problems caused by dust accumulation of a fan in the prior art. The air conditioner comprises an indoor unit, an indoor unit base and a fan and is characterized in that the indoor unit base is provided with a cleaning brush for cleaning the fan and a driving motor for driving the cleaning brush, and the cleaning brush is connected with the driving motor. When the tangential fan needs cleaning, a transverse air plate is closed, a fresh air exchanging fan is started, and the air conditioner operates in an air supply mode. When cleaning brush contact with the fan, the dust on the fan is cleared by the cleaning bush operating for a certain time.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, in particular to an air conditioner with an indoor fan automatic cleaning function. Background technique [0002] During the year-round operation of the air conditioner, a large amount of dust will be absorbed into the indoor unit of the air conditioner. Dust adheres to the heat exchanger of the indoor unit, which will affect the heat exchange performance of the heat exchanger and reduce the energy efficiency ratio and other performance coefficients. Dust is adsorbed on the indoor fan, which increases the load of the fan, reduces the air volume, increases the power consumption of the fan motor, affects the quality of the indoor air, and reduces the service life of the fan motor. Therefore, the indoor unit must be provided with a filter. However, if the filter is too thick, the fine dust cannot be filtered out, and if the filter is too fine, the air volume and cooling and heating capabil...
