In this case, the rubber blade 30 is fixedly attached to the outer surface of the windshield. 6 (b), when the outer slider 22 is positioned at the lower portion of the outer guide 110, the upper end of the outer slider 22 is engaged with the upper end of the sliding rail 120 The rubber blade 30 is fixed in a state of being spaced apart from the outer surface of the windshield.

7 is a vertical cross-sectional view showing an operation example of the window cleaning device of the present invention. 1 to 7, the operation of the window cleaning apparatus according to the present invention will be described. The outer cleaner 10 and the inner cleaner 70 are attached to the outer and inner surfaces of the windshield by the combination of the magnetic forces of the inner stationary magnets 80a and 80b facing the outer stationary magnets 20a and 20b, . 7 (a), when the handle connecting plate 84 is pulled up by holding the upper end of the inner cleaner 70, the handle connecting plate 84 is moved in the inner body 72 (The direction of arrow 1), and the inner slide 82 coupled to the handle connecting plate 84 moves in the downward direction (the direction of arrow 2) as described in FIG. In addition, since the inner slider 82 and the outer slider 22 are coupled by the magnetic force, the outer slide 22 is also moved downward (in the direction of arrow 3) along the sliding rail 120 of the outer guide 110 The lever drive arm 38 coupled to the outer slider 22 pulls down one end of the lever 34 and the rubber blade 30 rotates in the counterclockwise direction It is separated. At the same time, the upper end of the outer slider 22 is engaged with the upper slider 122 formed on the upper end of the sliding rail 120 by the attraction force with the inner slider 82 The state of progress of the operation is limited.

When the handle 60 of the inner cleaner 70 is pushed upwards in the upward direction while the rubber blade 30 is separated from the glass surface, the inner cleaner 70 moves the wash cloth 76 to the upper part of the window, And at the same time, the outer cleaner 10 is also moved upwards along the inner cleaner 70 while being cleaned by the cleaning cloth 14 to the upper part of the windshield. The inner slider 82 of the inner cleaner 70 is moved in the opposite direction to the inner slider 82 of the inner cleaner 70 because the upward movement of the outer slider 22 of the outer cleaner 10 is stopped by the upper stopper 122 of the sliding rail 120, The outer slider 22 of the outer vacuum cleaner 10 can not ascend and the rubber blade 30 of the outer vacuum cleaner 10 can not be lifted even though the outer slider 22 moves at a position slightly higher than the outer slider 22 of the outer vacuum cleaner 10. [ Is not brought into close contact with the glass surface. At the same time, in the magnet built in the outer slide 22, a rising thrust is generated which follows the magnet embedded in the inner slide 22, which moves in a slightly higher position in the opposite state, 12, so that the synchro rate at which the external cleaner 10 moves upward along the internal cleaner 70 is improved.

Thus, the glass window cleaning mechanism performs the primary cleaning while moving the rubber blade 30 from the glass window to the upper portion of the window, and then, as shown in FIG. 7 - (b) When the handle 60 is pulled downward (in the direction of arrow 1) for the purpose of secondary washing and water removal, the handle connecting plate 84 is moved in the inner body 72 And at the same time, the inner slider 82 is also quickly moved upward (in the direction of arrow 2). The inner slider 82 and the outer slide 22 are moved in the ascending process when the upper end point of the outer slider 22 of the outer cleaner 10 facing the lower end of the inner slider 82 passes, A repulsive force is generated between the magnets installed inside. The upper end of the outer slider 22 is moved away from the upper stopper 122 in the direction of an arrow ③ and moves to the upper end of the slide rail 120 along the upward movement of the inner slider 82 (In the direction of arrow 4) so as to face the inner slider 82. At this time, the lower end of the outer slider 22 is caught by the lower engaging jaw 124 formed at the lower portion of the sliding rail 120 (refer to FIG. 7C) 38 push up one end of the lever 34 and the lever 34 and the rubber blade 30 rotate clockwise (in the direction of arrow 5) to bring the rubber blade 30 into close contact with the windshield. In this state, as shown in FIG. 7C, the handle 60 of the internal cleaner 70 is continuously pulled downward to lower the internal cleaner 70 (in the direction of arrow 1) The external cleaners 10 and 70 are lowered together with the second washing and the water removal by the rubber blades 30 on the outer surface of the window is performed. At this time, the internal cleaner 70 moves downward ahead of the external cleaner 10. Even though the position of the internal slider 82 is lower than the position of the external slider 22, the external slider 22 The outer rubber blade 30 interlocked with the outer slider 22 tightly adheres firmly to the outer surface of the glass so that the removal of the perfect water . The coupling force between the magnet in the outer slide 22 and the magnet in the inner slide 82 which is lowered in opposition to the magnet in the outer slide 22 helps the lowering of the outer vacuum cleaner 10, The synchro rate for moving down along the slider 70 is improved.

As shown in FIGS. 7 (d) and 7 (d), after the cleaner is moved to the left or right in order to perform the continuous cleaning after cleaning by the vertical reciprocating operation of the window glass cleaning device, The inner slider 82 interlocked with the handle connecting plate 84 is moved upward in the upward direction (in the direction of arrow 1) as in the operation of Fig. 7 (a) By the repulsive force generated between the magnets at the time when the lower end point of the outer slider 22 of the outer cleaner 10 facing the upper end of the inner slider 82 is passed, The lower end of the outer slider 22 of the outer cleaner 10 moves away from the lower stopper 124 (in the direction of arrow ③) to the lower end of the sliding rail 120 along the inner slider 82 ) Inner slider 82 as shown in Fig. At this time, the upper end of the outer slider 22 is caught by the upper stopping protrusion 122 formed on the upper portion of the sliding rail 120 (refer to FIG. 7A) The outer rubber blade 30 interlocked with the outer rubber blade 30 is rotated counterclockwise (in the direction of arrow 5) to be spaced apart from the outer surface of the glass. Subsequently, when the handle 60 of the internal cleaner 70 is pushed up, the cleaning operation is performed while the blade 30 is lifted from the glass surface with the cleaning cloth as shown in Fig. 7 - (a).
