[DESCRIPTION]

[invention Title]

Automatic cleaning apparatus for glass window [Technical Field] The present invention relates to an automatic cleaning apparatus for a glass window, and more particular, to an automatic cleaning apparatus for a glass window which can tidily wipe a glass window using a brush in places such as high-rise buildings, apartments, and the like where people cannot directly wipe glass windows at the outsides while moving by itself through a repulsive force by a magnet of an outdoor unit and an electromagnet of an indoor unit in accordance with a radio control or an inputted instruction, so that the cleaning apparatus with light weight can be effectively operated.

[Background Art]

Conventionally, since it has been a difficult task for a worker especially to clean the exterior of glass windows due to a risk of accidents such as falling to the ground and the like in high-rise apartments or relative high buildings, this cleaning operation is achieved by a hired skilled worker who can wipe the glass windows on the outsides of the buildings while being suspended from a rope or a roof car, etc. However, there still exist dangers of safety accidents, etc, and it also causes economic burden for labor costs. Further, there occur problems in that below stairs may be suffered during a cleaning operation with water and in that glass windows are remained dirty for most of the year because frequent cleaning operation is impossible.

In addition, apparatuses for cleaning the exterior of glass windows in a room have been proposed and used, in which an outdoor unit and an indoor unit are respectively adsorbed on the outer and inner surfaces of a glass window by a magnet and the like with the glass window interposed therebetween so that a cleaning operation can be obtained by the outdoor unit moved based on the movements of the indoor unit. Nevertheless, there still occur problems in that the outdoor unit is detached from the exterior of the glass window and dropped to the ground due to excessive movements of the indoor unit, which results in inflicting damages on passerbys as well as causing breakdown of the outdoor unit and the like.

To solve the above problems, a Korean Patent application No. 10-1999-15374 entitled "window cleaning apparatus by automatic vertical and lateral movement" has been suggested, in which the exterior of a glass window having difficulty in wiping a glass window of high-rise apartments or buildings can be automatically wiped without relying on a skilled worker by allowing a user to readily install a rail moving member on the frame of the glass window and insert a cleaning implement for the glass window into the rail moving member while the cleaning implement is laterally moved along a rail, to thereby allow the window to be safely and easily cleaned frequently as well as prevent the cleaning implement or cleaning water from being dropped to the ground.

However, such a conventional window cleaning apparatus by automatic vertical and lateral movement as described above has shortcomings in that there cause troublesome tasks in which the rail moving member has to be installed at the window frame and in which the rail to which the cleaning

implement is inserted has to be moved along the rail moving member. [Disclosure] [Technical problem] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an automatic cleaning apparatus for a glass window which can tidily wipe a glass window using a brush in places such as high-rise buildings, apartments, and the like where people cannot directly wipe glass windows at the outside, while moving by itself through a repulsive force by a magnet of an outdoor unit and an electromagnet of an indoor unit in accordance with a radio control or an inputted instruction, so that the cleaning apparatus with light weight can be effectively operated.

In order to accomplish the above objects, according to the present invention, there is provided an automatic cleaning apparatus for a glass window, comprising an outdoor unit which includes a relatively large and strong annular S- pole magnet mounted on the center of a surface confronting the glass window (hereinafter refers as "a front surface") thereof, an annular cloth member formed around the outer circumference of the strong S-pole magnet, an annular brush formed around the outer circumference of the annular cloth member, and a plurality of N-pole magnets and S-pole magnets mounted inside of the outdoor unit in such a manner as to be alternately arranged around the outer circumference of the strong S-pole magnet; and an indoor unit which includes a relatively large and strong annular N-pole magnet

mounted on the center of a surface confronting the glass window (hereinafter refers as "a front surface") thereof, an annular rubber ring mounted around the outer circumference of the strong N-pole magnet, an annular cloth member formed around the outer circumference of the rubber ring, an annular brush formed around the outer circumference of the annular cloth member, and a plurality of electromagnets mounted inside of the indoor unit in such a manner as to be arranged around the outer circumference of the N-pole magnet at small intervals, wherein the indoor unit further includes a printed circuit board mounted inside thereof so that the polarity of the plural electromagnets can be changed based on manipulation of a key matrix switch positioned on the printed circuit board or a setting received by radio, to thereby allow the indoor unit to be rotated on the spot and to be moved, and wherein a user's setting based on the state where a key matrix switch of a remote controller is manipulated is transmitted by radio signals to the indoor unit so that a remote control operation can be performed, thereby reducing the weight of the outdoor unit, and hence facilitating the movement or operation of the outdoor unit, as well as being without any fear of an accident even when the outdoor unit is fallen down to the ground due to the failure of the magnetism of the outdoor unit.

The indoor unit 20 further includes a shielding plate 28 mounted between a light emitting element 26 and a light receiving element 27, which are formed in a rear surface of the indoor unit 20 in such a manner as to be coupled to a center axis 28a so as to be rotated about the center axis 28a and adapted

for recognizing the rotation state thereof, and a printed circuit board 29 coupled to the light emitting element 26 and the light receiving element 27 so as to control the internal operation of the indoor unit 20, and coupled to an antenna 30 so as to transmit or receive radio signals to or from a remote controller 40 via the circuit configuration as in FIG. 5.

FIGs. 3 and 4 are views a state where a glass window is cleaned by means of the outdoor unit and the indoor unit according to an embodiment of the present invention.

The relatively large and strong annular S-pole magnet 11 is mounted on the center of the front surface of the outdoor unit 10 and abuts against the exterior surface of the glass window 100, and the annular N-pole magnet 21 is mounted on the center of the front surface of the indoor unit 20 and abuts against the interior surface of the glass window 100, so that a stable adhesion can be achieved.

The annular brush 13 having a relatively small width ranging from the inner circumference to the outer circumference thereof is formed around the outer circumference of the annular cloth member 23 of the outdoor unit 10 and adapted for removing foreign substances adhering to a surface of a glass window.

The annular cloth member 12 having a relatively large width ranging from the inner circumference to the outer circumference thereof is formed around the outer circumference of the annular S-pole magnet 11 of the outdoor unit 10 and adapted for wiping foreign substances adhering to a surface of a glass window. The annular brush 24 is formed around the outer

circumference of the annular cloth member 23 of the indoor unit 20 and adapted for wiping foreign substances adhering to a surface of a glass window.

The annular cloth member 23 having a relatively large width ranging from the inner circumference to the outer circumference thereof is formed around the outer circumference of the brush 24 and adapted for wiping foreign substances removed from a surface of a glass window 100.

The plurality of N-pole magnets 14, 14a, and S-pole magnets 15, 15a are mounted inside of the outdoor unit 10 in such a manner as to be alternately arranged around the outer circumference of the large and strong S-pole magnet 11 mounted in the center of the outdoor unit 10, and a plurality of electromagnets 25 are mounted inside of the indoor unit 20 in such a manner as to be, at small intervals, arranged around the outer circumference of the large and strong N-pole magnet 21 mounted in the center of the indoor unit 20, so that the polarity of the plural electromagnets 25 can be changed to each other based on the control through the printed circuit board built-in the indoor unit 20. At this time, both of the outdoor unit 10 and the indoor unit 20 are rotated in a predetermined direction by means of a push/pull force generated between the plural electromagnets 25 of the indoor unit 20 and the plural N-pole magnets 14, 14a and S- pole magnets 15, 15a of the outdoor unit 10.

In this regard, a removing operation for removing the foreign substance by the brush 13, 24 and a wiping operation for wiping the foreign substances removed from the annular cloth member 12, 23 are effectively carried out through the rotation force.

Meanwhile, a rubber ring 22 is mounted around the outer circumference of the strong N-pole magnet 21 mounted on the center of the front surface of the indoor unit 20, so that when the rubber ring 22 abuts against a surface of a glass window 100 by an eccentric force generated while the indoor unit 20 is rotated on the spot, it can be laterally moved in some degree by a force apt to rotate, and thus the surface of the glass window 100 can be wiped in its entirety by the movement of the rubber ring 22. FIG. 5 is a block diagram showing a schematic configuration for operation of the present invention.

When a user inputs options for cleaning the glass window through a key matrix switch 41 of the remote controller 40, a micro processor 43 to which an electric power is supplied from a battery 42 controls a liquid crystal display 44 to numerically display information based on the operations or options thereon.

Here, the micro processor 43 has a program for operation stored in a FLASH ROM 46 as a nonvolatile memory while temporarily storing information based on the operations in a SDRAM 45 so as to allow electromagnet driving signals and the like for cleaning the glass window to be transmitted or received as radio signals through an antenna 48 via a transmitting and receiving IC 47. The transmitting and receiving IC 31 of the indoor unit 20 receives or transmits information for cleaning the glass window from or to the remote controller 40 through the antenna 48, and transmits the information to a micro processor 32. Further, the micro processor 32, to which the options for cleaning the glass window inputted by a user

through the key matrix switch 33 is transmitted and an electric power is supplied from a battery 34, generates a control signal for driving the plural electromagnets 25.

Further, the micro processor 32, which controls the internal operation of the automatic cleaning apparatus in a state where a program for operation is stored in an EEPROM 37 and a FLASH ROM 36 as nonvolatile memories while temporarily storing information based on the operations stored in a SDRAM 35, generates the electromagnet driving signal for cleaning the glass window after recognizing the current orientation of the outdoor unit 10 and the indoor unit 20, as a light of the light emitting element 26 is prevented from being incident to the light receiving element 27 by the shielding plate 28 only when the shielding plate 28 is oriented downwardly by the weight itself of the shielding plate 28.
