The air conditioner comprises an air conditioner indoor unit and an air conditioner outdoor unit. When the cleaning mechanism 100 of a fan in an air conditioner is used for an air conditioner indoor unit, cleaning liquid is usually placed in a cleaning liquid tank outside the air conditioner indoor unit, one end of a liquid inlet pipe 110 extends to the outside of the air conditioner indoor unit through an air inlet of an air inlet grid of the air conditioner indoor unit and extends into the cleaning liquid tank so as to convey the cleaning liquid in the cleaning liquid tank into a containing cavity 142 through a liquid adding port 141. It will be appreciated that a liquid pump may be provided in the cleaning liquid tank to facilitate delivery of cleaning liquid into the receiving chamber 142. The liquid inlet pipe 110 may be a silicone tube, a rubber tube or a plastic tube, and specifically may be adaptively set according to the components of the cleaning liquid and the actual requirements, which is not limited herein.

In some embodiments, the cleaning mechanism 100 of a fan in an air conditioner is used for an outdoor unit of the air conditioner, and one end of the liquid inlet pipe 110 extends out of the outdoor unit of the air conditioner through a housing of the outdoor unit of the air conditioner and extends into the cleaning liquid to convey the cleaning liquid into the accommodating cavity 142 through the liquid inlet 141.

The cleaning liquid may be water or a cleaning agent. When the cleaning liquid is water, the dust and foreign matter on the fan 200 are cleaned by spraying the water onto the fan 200 to dissolve the dust and foreign matter on the fan 200 into the water. It will be appreciated that the cleaning agent may remove not only dust and foreign matters from the fan 200, but also bacteria in the air conditioner indoor unit, and remove odor of the air conditioner indoor unit.

In particular, the liquid inlet pipe 110 delivers the cleaning liquid into the accommodating chamber 142, and the cleaning liquid in the accommodating chamber 142 contacts the liquid spraying holes 143 and is sprayed onto the fan 200 in the indoor unit of the air conditioner through the liquid spraying holes 143.

Referring to fig. 1, in some embodiments, spray aperture 143 is a conical aperture with the small diameter end of spray aperture 143 being configured to face fan 200.

The pressure of the cleaning liquid sprayed from the conical hole is larger after the cleaning agent is pressurized by the conical hole, and the small diameter end of the liquid spraying hole 143 faces the fan 200, so that the distance of the liquid spraying hole 143 spraying the cleaning liquid towards the fan 200 is longer, and the spraying range is larger.

Referring to FIG. 1, in a specific implementation, spray apertures 143 have diameters of 2.5mm-3.5mm, and spray apertures 143 have tapers of 9-15.

It is understood that when the diameter of the liquid spraying hole 143 is smaller than 2.5mm, the efficiency of spraying the cleaning liquid by the liquid spraying hole 143 is low; when the diameter of the spray hole 143 is greater than 3.5mm, the displacement of the cleaning liquid sprayed from the spray hole 143 in the horizontal direction is relatively close, which may result in that a part of the cleaning liquid cannot be sprayed onto the fan 200, and thus the diameter of the spray hole 143 is 2.5mm to 3.5mm. If the taper of the liquid spraying hole 143 is larger than 15 degrees, the area of the small-diameter end of the liquid spraying hole 143 is smaller, and the efficiency of spraying the cleaning liquid by the liquid spraying hole 143 is lower; if the taper of the spray hole 143 is less than 9 °, the pressure of the cleaning liquid in the spray hole 143 is small, and the distance of the cleaning liquid sprayed from the spray hole 143 is short, so that the taper of the spray hole 143 is 9 ° -15 °.

Illustratively, spray apertures 143 have a diameter of 3mm, and spray apertures 143 have a taper of 10 degrees.

In some embodiments, the side of the accommodating cavity 142 facing the fan 200 is rectangular, and the spray holes 143 are arranged in a rectangular array, so that the number of the spray holes 143 is large, and the efficiency of spraying the cleaning liquid to the fan 200 by the spray member 120 is high. The number of the liquid spraying holes 143 may be adaptively set according to the area of the side of the receiving chamber 142 facing the fan 200 and the diameter of the liquid spraying holes 143, which is not limited herein.

The liquid inlet tube 110 is usually a hose, and if the fluid pressure in the liquid inlet tube 110 is high, the liquid inlet tube 110 is easily separated from the liquid filling port 141, so that the cleaning liquid leaks. Therefore, the fixing portion 133 is provided on the mounting portion 130, and the fixing portion 133 is located above the filling opening 141 and communicates with the filling opening 141 to fix the liquid inlet tube 110 at the front end of the filling opening 141, thereby preventing the liquid inlet tube 110 from being separated from the filling opening 141.

It can be appreciated that the profile of the fixing portion 133 is matched with the profile of the liquid inlet tube 110, and the cross-sectional area of the fixing portion 133 is slightly larger than that of the liquid inlet tube 110, so that the liquid inlet tube 110 is conveniently communicated with the liquid filling port 141 through the fixing portion 133, and meanwhile, the liquid inlet tube 110 is relatively fixed in the fixing portion 133.

Referring to fig. 1, 7 and 8, in some embodiments, the mounting portion 130 has at least one positioning rib 134 on an outer side surface thereof, the positioning rib 134 being used to position the attachment position of the mounting portion 130 to the duct housing 300.
