When the float switch detects that the water level rises to the set water level, the electromagnetic valve is closed to block the tap water pipe.
One of the dust removing mechanisms, the mounting frame 18 is provided with a second motor 21, and the second motor 21 is in transmission connection with the dust removing roller 17 through a synchronous belt 6 and a synchronous wheel 7. Because the dust removal roller 17 and the roller shutter 8 are in sliding friction dust removal, only one part of the dust removal roller 17 is in contact with the roller shutter 8, and after the current contact part is wiped, the dust removal roller 17 is driven by the second motor 21 to rotate for a certain angle, so that the other part of the dust removal roller 17 is continuously wiped on the roller shutter 8. The process is circulated, so that the whole dust removing roller 17 is fully utilized, and the dust removing effect of the roller shutter 8 is improved.
The second motor 21, the water pump and the telescopic motor 19 are respectively electrically connected with the controller, the controller controls the work of the controller, and the working time of the dust removing mechanism and the spraying mechanism is set through a remote controller of the air conditioner. For example, once every 15 days, once every 30 days, or once every 40 days, and the user is set according to the current environment.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
