Detailed Description of the Invention
Referring now in detail to the drawings for the purpose of illustrating the present invention, the cleaning apparatus 1 as shown in FIGS. 1 and 3 comprises wheels 3 having coaxial gears 3, and a shaft 10, and a conveyor belt 4 connected to first conveyor guiding rollers 6' secured to driving gear 8 which gears with the coaxial gears 3'. A wiping belt 5 operatively contacts the conveyor belt 4 at a location in front of second conveyor guiding rollers 6 of the conveyor belt 4. The conveyor belt 4 includes a plurality of conveying members 4' disposed thereon for conveying the trash from the floor to the trash containing corner 2. The wiping belt 5 engages first wiping guiding rollers 7' and the second wiping guiding rollers 7. The conveyor belt 4 and wiping belt 5 rotates, respectively, in the opposing direction to each other for effectively storing the trash in a plurality of chambers between the plurality of conveying members 4' while the apparatus 1 are operated by the user.
Brushes 9 are associated with the conveyor belt 4 and wiping belt 5, respectively, for cleaning off the dust, dirt, trash, or the like from the belts 4 and 5.
A sponge container 12 is associated with a wet sponge 12' for supplying liquid to the wiping belt 5. The trash recovered by the cleaning apparatus 1 collects in the corner of the trash containing corner 2. The cleaning apparatus 1 is also provided with a handle 13.
As shown in FIG. 1, a front cover or dustpan 11 which is attached by hinges 14 and extends over a second guiding rollers 7 of the wiping belt 5. A cover 15, to which the handle 13 is secured, extends over the shaft 10 of the wheels 3. The rear cover 16 connects to a base member 17 to form the trash containing corner 2 disposed at the corner portion between the rear cover 15 and the base member 17. The rear cover 16 is connected to the cover 15 through hinges 18.
The sponge container 12 attached to the interior surface of the cover 15 in vicinity of the portion of the wiping belt 5 is provided with a wet sponge 12' disposed therein for supplying moisture to the wiping belt 5 through sliding contact with each other. The conveyor belt 4 includes the plurality of conveying members 4' for distribution the dust, dirt and trash 19 from a floor 20 to the corner container 2. While the cleaning apparatus of the present invention is operated, the trash is transferred to a plurality of chambers disposed between the conveying members 4' and simultaneously, the wiping belt 5 covers the chamber for effectively protecting the trash from dropping from the cleaning apparatus 1. The coaxial gears 3' gear with driving gears 8 which include the first conveyor rollers 6' as a coaxis for rotating the conveyor belt 4 operatively associated with the second conveyor roller 6.
Referring in detail to FIG. 3, there is illustrated another embodiment of a cleaning apparatus 1 in accordance with the present invention. If there is demand to clean a large amount of the trash on the floor 20, the cleaning apparatus 1 can comprise an auxiliary belt 5a having a plurality of conveying members 5a' which engage with the second guiding rollers 7 of the auxiliary belt 5a. Also, coaxial gear wheels 13' can be rotated on the floor 20 for easily operating the auxiliary belt 5. Therefore, the conveyor and auxiliary belts 4 and 5a having both plurality of conveying members 4' and 5a', respectively, are operated in cooperation for the transportation of the trash 19 from the floor 20 to the trash containing corner 2.
According to the present invention, the cleaning apparatus operates as follows: Water or a cleaning oil is supplied to the sponge container 12 predetermined by the cleaning purpose of the floor 20. At this time, when the user pushes the cleaning apparatus 1 using the handle 13, the wheels 3 rotate, the coaxial gears 3' rotate which in turn rotate the driving gears 8. The gears 3' make the driving gears 8 rotate which correspondingly rotate the first conveyor guiding rollers 6'. The second conveyor guiding rollers 6 are rotated through the conveyor belt 4. Also, the second wiping guiding rollers 7 are rotated by the pushing force of the operator. The dust and/or trash 19 is collected by the conveyors and wiping belts 4 and 5 and separated from the belt 4 to the trash containing corner 2 by cleaning the belt 4 with the brush 9'. At that time, as shown in FIG. 1, the wiping belt 5 rotates, and the belt 5 coated by the water or cleaning oil slidably contacts with the floor 20 for wiping and cleaning the floor 10. Accordingly, the floor 19 is wiped by the belt portion disposed at the second wiping guiding rollers 7 (FIGS. 1 and 2).
Also, according to another embodiment of the present invention, the floor 19 may be cleaned by the conveyor and auxiliary belts 4 and 5a having the plurality of conveying members 4' and 5a' (FIG. 3).
Because the cleaning apparatus of the present invention includes both a sweeping system and a wiping system disposed therein for simultaneously cleaning up the floor, it is very convenient for cleaning and is inexpensive to purchase. Also, it takes only a short time to clean a surface by utilizing the cleaning apparatus of the present invention when compared with conventional cleaning devices. Furthermore, the cleaning apparatus having the conveyor belt 4 which is operatively associated with the wiping belt 5 or the auxiliary belt 5a for effectively transporting the dust, dirt, trash or the like 19 to the trash containing corner 2 since the belts 4 and 5 or 5a tightly contact to store the trash 19 in the chambers formed therebetween even though the apparatus 1 is suddenly jolted.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included in the scope of the following claims.
