Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to cleaning apparatus, and more particularly to an automate glass surface cleaning machine which is adapted for cleaning a glass surface while residual cleaning water is sucked into the cleaning machine so as to prevent water stain remaining on the glass surface.

2. Description of Related Arts

Conventionally, in order to clean a glass surface, a wiper is commonly used. Moreover, a detergent, such as soap water, is first applied on the glass surface for removing dirt thereon. Sometimes, clean water is further used to wash off the soap water on the glass surface. Then, the wiper is used to wipe off the residual cleaning water on the glass surface so as to prevent water stain remaining on the cleaned glass surface.

However, the wiper has a relative small size with respect to the glass surface such that water may still leave on the glass surface along two side ends of the wiper while wiping the glass surface. So, a cleaner must dry or clean the wiper every time after each wiping and keep repeatedly wiping the glass surface until all water is removed from the glass surface. If any water is not removed on the glass surface, watermarks will remain on the glass surface. Practically, it is more difficult to clean the watermarks later. Thus, it not only is a hassle for drying the water on the wiper but also takes more time to clean the glass surface.

Especially when the cleaner needs to clean the glass surfaces of a tower building, he or she must be hung over the tower for a period of time. When the glass wall surfaces are very dirty, the cleaner must take time to mop up the dirt on the glass wall surfaces. The longer the cleaner stay over the tower, the more the dangerous he or she is.

During wiping operation, water normally stays on two side ends of the wiper blade 20′. So, the two fluid suction nozzles 31′ are adapted for removing the water at two side ends of the wiper blade 20′ so as to prevent the water stained on the glass surface S.
For home usage, the user may be a housewife who may not need a powered cleaning machine such that the automate glass surface cleaning machine preferably comprises a [0043] handle frame 70 rearwardly extended from the rear portion of the supporting frame 10. It is worth to mention that the automate glass surface cleaning machine can be simply constructed without the motor 32 for household usage so as to reduce the overall weight of the automate glass surface cleaning machine such that the cleaner can easily operate the present invention manually, as shown in FIG. 6.
Accordingly, the user may press the mopping [0044] element 412 of the mop roller 41 against the glass surface S and rub the mop roller 41 up and down to clean the glass surface S. The resilient elements 423 of the coupling joints 42 will provide a resistant force to ensure the mop roller 41 pressing against the glass surface. In order to achieve better cleaning effect, the user may also operate the fluid spray device 50 to supply fluid detergent from the fluid detergent supply bin 51 onto the glass surface S through the spray head 52 by controlling the operation trigger 53.
FIG. 3 illustrates the automate glass cleaning machine working on a vertical glass surface S. Since [0045] wiper blade 20 and the suction opening 311 is positioned right above the mop roller 41, when the mop roller 41 rolls downwardly to rub and clean the glass surface S, cleaning water may remain on the rubbed glass surface and the automate glass cleaning machine can substantially clean such cleaning water remained on the glass surface S at the same time during the downwardly continuous wiping motion of the automate glass cleaning machine. Practically, when the mop roller 41 rolls and rubs from an upper portion to a lower portion of the glass surface S to clean it, the wiper blade 21 will be positioned right at that upper portion of the glass surface S to wipe over that upper portion of the glass surface S so as to wipe off the residual fluid detergent or cleaning water remained thereon to a rear side of the wiper blade, and then the suction opening 311 which is positioned just adjacent to the rear side of the wiper blade 20 will suck up such residual fluid detergent or any cleaning water to store in the fluid receiving chamber 101. In other words, the cleaning of the glass surface and the removal of the cleaning fluid can be completed at the same time simply by a single action of rubbing the automate glass cleaning machine downwardly against the glass surface. lots of whereins; not for sure whether to p1 or not
