SUMMARY OF THE INVENTION In order to solve this problem, the present invention relates to a cleaning apparatus for an indoor unit of an air conditioner mounted on a wall in a room, and the remaining surface except for the back surface of the indoor unit of the air conditioner. It consists of a frame made of metal wires etc. that can be hung on the air conditioner indoor unit while guarding it, and a synthetic resin cover that hangs over the frame and covers the remaining surface except the back of the air conditioner indoor unit, The gist of the invention is that a water reservoir is formed at a lower end of the cover. Further, in the present invention, the front cover portion and the rear cover portion of the cover are welded to each other by heat sealing at appropriate intervals between both left and right end portions at the upper position of the lower water sump portion of the cover, and between the adjacent welding portions. The invention is characterized in that a narrow passage for guiding the dirty cleaning liquid to the lower water reservoir is formed. Further, the present invention is characterized in that a tray having an upper end engaged with an engaging portion formed at a lower end of the frame to receive a lower end water reservoir of the cover is provided.

With this configuration, it is not necessary to extend the waste discharge pipe near the floor as in the conventional example and to prepare a bucket or the like for receiving a dirty cleaning liquid at the lower end of the waste discharge pipe. Dirty cleaning liquid can be received in the lower end water reservoir of the cover, and workability can be improved. In addition, the front cover portion and the rear cover portion of the cover are welded to each other by heat sealing at appropriate intervals between the left and right end portions, and a narrow passage that guides the dirty cleaning liquid to the lower sump portion between the adjacent welding portions. Because it is formed, even if the cover falls on the floor when removing the cover from the frame, for example, all of the dirty cleaning liquid in the lower water reservoir does not instantaneously spill on the floor,
Since the amount of the cleaning liquid leaks from the narrow passage, the amount of the cleaning liquid that spills on the floor is small, so that it does not take much time for the subsequent cleaning. Further, by engaging the tray with the engaging portion formed at the lower end of the frame and receiving the lower water reservoir of the cover with the tray, the weight of the dirty cleaning liquid accumulated in the lower water reservoir can be supported by the tray. And work safety can be improved.
