DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for cleaning an air conditioner, and more particularly to a cover for a business such as a bank, a hotel, a hospital, a pachinko hall, etc., which is simple and easy to use. The present invention relates to a cover for cleaning an air conditioner, which can be cleaned at a high speed.

[0002]

2. Description of the Related Art In recent years, the demand for air conditioners, coolers and heaters (hereinafter referred to as "air conditioners") mounted on ceilings and wall surfaces has been increasing rapidly, not only for business use and home use, but has been well received. . This air conditioner has a filter inside the air intake and exhaust ports of the air conditioner for adhering dust and tobacco smoke contained in the air taken in.The filter is periodically cleaned. I have. However, if the air conditioner is used for a long time, dirt that cannot be removed by the filter alone adheres to the air conditioner, and molds and ticks generated from dust naturally propagate in the air conditioner. Therefore, the inside of the air conditioner is regularly cleaned by a cleaning worker so that cleaning water is rushed into the air conditioner from a nozzle of the washing machine by a pump or the like to remove dirt in the air conditioner.

When performing this cleaning operation, a cleaning cover is always used so that dirty cleaning water does not fly into the room. However, the conventional ceiling-mounted and ceiling-hanging type air conditioner cleaning covers are made of highly transparent and durable film. Since black sewage is transmitted from inside to the inside of the cover main body and flows down, the inside of the cover main body becomes dirty, and the state of the inside of the air conditioner cannot be seen by the operator at all from the outside.

[0004] For this reason, for example, Japanese Patent No. 2840596
As in the case of No. 1, the opening and windows with adhesive tape are provided on the cover body, from which various ideas are aimed at improving the function of the cleaning cover so that the operator can see inside the air conditioner while working. Something has been devised. However, on the other hand, the structure of the above patented invention is inevitably complicated, so that the cleaning operation is very complicated, and the operator is difficult and inconvenient to perform the cleaning operation, and it is difficult to perform the cleaning operation efficiently. there were.

[0005] In particular, ropes are set on four sides to attach the cleaning cover to the air conditioner body, but the air conditioner body has various sizes, and clips and laundry clips are used to correct bending and position. . In addition, since the cleaning cover itself is very expensive at 15,000 to 30,000 yen per sheet, the contractor often uses the dirty cleaning cover many times, so hospitals, coffee shops, pachinko parlors, etc. Complaints about unsanitary extremes are constantly being made. Therefore, a comfortable environment cannot be expected. Furthermore, the blind spot of conventional cleaning covers is that they use thick sheets that are too durable and long lasting, assuming that water is too heavy. As a result, the price is inevitably high and complicated processing is performed. However, ultimately, the cleaning cover is not intended to contain water in the cover body itself, but only to flush the cleaning water inside the cover body. Therefore, although it is not necessary to consider the weight ratio of water, it is very wasteful and uneconomical to actually provide a cleaning cover using a film made of expensive materials. was there.

[0006]

Accordingly, there has been a strong demand from cleaning contractors for the emergence of a cleaning cover that can perform the cleaning operation easily and easily and at a low cost and efficiently.

[0007]

SUMMARY OF THE INVENTION In view of the above, the present invention has been made, and the gist of the present invention is that an upper edge portion of a substantially inverted strawberry-shaped cover body made of a polyethylene-made dioxin film is provided. An opening which can be freely extended and retracted is provided with an elastic cord interposed therebetween, and a flange portion of a plastic cap having a T-shaped cross section is polymerized with a film at the bottom opening of the cover body, and the cover is formed by three-piece welding. A cap is integrally formed at the bottom opening of the main body, and a drainage tube made of polyethylene film is detachably clamped and fixed to the lower part of the cap with a fixed cylinder, making it easy and easy to clean the air conditioner regularly. An air-conditioning cleaning cover and a cap are provided with a non-slip protruding portion at a central outer peripheral portion thereof to provide a comfortable environment. Regarding air conditioner cleaning cover according to claim 1 with improved fastness maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an air conditioner cleaning cover according to the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a cover body having a so-called inverted strawberry shape, which is formed in a downwardly tapered shape made of a polyethylene-made dioxin film. The upper edge of the cover body 1 is bent with an elastic cord 2 interposed therebetween. Thereafter, the bent portion is welded 4 to provide an opening 3 that can be freely expanded and contracted. Reference numeral 5 denotes a bottom side opening of the cover body 1, and reference numeral 6 denotes a hollow T-shaped plastic cap having a flange portion 7 at an upper portion and non-slip projections 8 and 8 'at a central outer peripheral portion. Then, the cap 6 is inserted into the bottom opening 5 of the cover body 1 from the cylindrical portion of the cap 6 by using the expansion and contraction force of a polyethylene-removed dioxin film, and the flange 7 is pressed onto the bottom of the cover body 1. If you do
A polyethylene film 9 made of the same material as the cover body 1 is fitted upward from the lower part of the cap 6 and is brought into close contact with the bottom lower surface of the cover body 1. At this time, the lower surface of the film 9 is provided with the non-slip projection 8 above the cap 6.
Are in opposition.

When the flange 7 of the cap 6 is superimposed on the upper surface of the bottom of the cover body 1 and the film 9 is superimposed on the lower surface of the bottom of the cover body 1, the three members are welded to form a cap. 6 is formed integrally with the bottom opening 5 of the cover body 1. Reference numeral 10 denotes a drainage tube made of a polyethylene film. After fitting the upper part of the drainage tube 10 into the lower part of the cap 6, the fixing tube 11 is inserted and the drainage tube 10 is detachably clamped and fixed to the cap 6. . At this time, as shown in FIG. 3, the upper end of the drainage tube 10 hangs down, and the curved portion of the drainage tube 10 comes into contact with the anti-slip projection 8 ′ at the lower portion of the cap 6.
