[20] Technical objects achieved by the present invention and embodiments of the present invention will become apparent through preferred embodiments of the present invention described below. The following embodiments are only exemplarily provided to describe the present invention, and do not limit the scope of the present invention.
[21] A detailed description of the present invention will be provided below with reference to the attached diagrams.
[22] To describe an automatic washing device for a building that automatically washes the outer walls or windows, etc. of a building, with reference to FIG. 1, the automatic washing device 1 is formed largely of a winch 10, a housing 20, a rotating brush 30, and height controlling blocks 40, where the rotating brush 30 installed in the housing 20 moves along the height controlling blocks 40 to clean the outer walls of a building, and the housing 20 in which the rotating brush 30 is mounted is supported by the winch 10 on the roof of the building.
[23] Specifically, the winch 10 is fixedly installed on the roof of the building and connected to the housing 20 by wires 11, an air tank 12 and a water tank 13 are installed to the left and right, respectively, on the winch 10, an air hose 12a is connected to the air tank 12 to supply air to the outer walls of the building, and a water hose 13a is connected to the water tank 13 to supply water to the outer walls of the building.
[24] Also, the housing 20 connected to the winch 10 through the wires 11 has a plurality of rotating brushes 30 fixed therein, which are raised or lowered along the outer wall of the building through pulling or releasing of the wires 11, such that the rotating brushes 30 directly contact the outer wall of the building to wash the outer wall of the building through rotating. A driving gear 31 is respectively installed at each end of each rotating brush 30, and the driving gears 31 are rotated along the height controlling blocks 40 so that the rotating brushes 30 can freely be raised or lowered along the outer wall of the building.
[25] Thus, the automatic washing device 1 for a building transfers air and water to the housing 20 through the winch 10, washes the outer wall of the building by rotating the rotating brushes 30 after discharging air and water onto the outer wall of the building from the housing 20, and performs automatic washing sequentially of the entire outer wall of the building through raising or lowering the rotating brushes 30 along the height controlling blocks 40.
[26] Here, to describe the automatic washing device 1 configured with the housing 20 and the rotating brushes 30, with reference to FIGS. 2 and 3, inside the housing 20, a plurality of rotating brushes 30 constitutes 2-4 rows, and the brushes are disposed apart a predetermined distance from one another in mutually intersecting directions. Also, a plurality of air discharging pipes 21 and water discharging pipes 22 are installed at predetermined intervals from one another inside the housing 20 to sequentially discharge air and water onto the outer wall of the building. An air line 23 that supplies air to the air discharging pipe 21 in an intersecting direction, a water supply line 24 that supplies water to the water discharging pipe 22, and a hydraulic line 25 for driving the device, are respectively installed at the central portion of the housing 20.
[27] That is, by discharging air onto the outer wall of the building through the air discharging pipe 21 installed in the housing 20, dust or impurities are removed, and then by discharging water through the water discharging pipe 22 onto the outer wall of the building, and through rotation of the rotating brushes 30, the outer wall of the building is washed automatically.
[28] In addition, the air discharging pipe 21 receives air from the air line 23 so that it may discharge air onto and dry the outer wall of the building after the latter is washed.
[29] To describe the height controlling blocks 40 that fix both left and right ends of the rotating brushes 30, with reference to FIG. 4, the height controlling blocks 40 receive and fixedly install the ends of the rotating brushes 30 to the left and right sides, respectively, of the building in vertical directions, and height controlling rack gears 41, to which the driving gears 31 of the rotating brushes 30 are engaged, are assembled to and installed in the height controlling blocks 40.
[30] Here, the height controlling blocks 40 are formed in a 'C shape and are configured with the height controlling rack gears 41 formed of rubber plates fixedly installed therein by means of a plurality of bolts, and the driving gears 31 of the rotating brushes engaged to the height controlling rack gears 41 are rotated to raise or lower the rotating brushes 30 along the height controlling blocks 40.
[31] Also, to describe rotating rods 50 that rotate the rotating brushes 30, with reference to
FIG. 5, the rotating rods 50 are installed within the rotating brushes 30 and rotate to rotate the rotating brushes 30. A bearing housing 52 receiving a plurality of bearings 51 is installed at either end of the rotating rod 50, and a constant velocity joint 53 and a sub bearing 54 are respectively installed at one side of the bearing housing 52 to control the rotating speed of the rotating rod 50, so that the rotating rod 50 rotates at a constant speed to operate the rotating brush 30.
[32] Further, with respect to the rotating brush 30 rotating together with the rotating rod
50, as shown in FIG. 6, the rotating brush 30 has a bearing 51 installed at either end thereof, with a wheel 32 assembled to the outer periphery of the bearing 51, and a tire 33 assembled and installed to the outer periphery of the wheel 32 to contact the outer wall of a building.
[33] Specifically, the rotating brush 30 contacts the outer wall of the building such that the tire 33 contacts and is fixed against the outer wall of the building during washing, thereby securely operating the rotating brush 30, and the tire 33 elastically contacts the outer wall of the building so that it rises or descends through rotation and moves together with the rotating brush 30 and aids in washing the outer wall of the building.
[34] Moreover, the rotating brush 30 is formed of a special coating cloth of an approximate length of 50 cm in order to rotate while contacting the outer wall or windows of the building and clean those surfaces, and the housing 20 or the rotating rods 50, etc. forming the automatic washing device 1 for a building may be made of lightweight and strong Duranium to more effectively operate the device.
[35] To describe the driving gears 31 used to rotate the rotating brushes 30, with reference to FIG. 7, the driving gears 31 of the rotating brushes 30 are engaged to an operating gear 34 operated by a hydraulic motor, and a main bearing 35 and a sub bearing 54 are installed respectively to the inside of the driving gear 31, so that when the operating gear 34 is rotated through operation of the hydraulic motor, the driving gear 31 engaged thereto is rotated to rotate the rotating rod 50 and the rotating brush 30, whereupon the rotation of the rotating rod 50 is performed smoothly due to operation of the main bearing 35 and the sub bearing 54.
[36] Accordingly, because the above-described automatic washing device 1 for a building has a simple configuration to be effectively used, efficiency for washing the outer wall of a building can be increased, and because washing of the building is fully automated, safety can be provided for workers, and maintenance and repair of the device can also be made more convenient.
[37] While an embodiment of the present invention has been exemplarily described above, it will be apparent to those having ordinary skill in the art that various modi- fications and other similar embodiments can be derived.
