Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a cleaning device for cleaning an exterior wall surface of a building, and more particularly, to a cleaning device for cleaning the exterior wall surface of a building by spraying and wiping a cleaning liquid on a building exterior wall surface such as a window or an exterior wall surface of a building, It is possible to effectively reduce the amount of cleaning liquid used for cleaning the exterior wall surface of the building by scattering the cleaning liquid on the exterior wall surface of the building, thereby omitting or reducing the configuration for collecting the waste cleaning liquid, The present invention also relates to an apparatus for cleaning an exterior wall of a building, which is provided with a wiper member that can reduce the overall weight of the apparatus and the like.

FIG. 7 is a schematic perspective view of a conventional cleaning apparatus disclosed in Korean Patent No. 10-1276068, which is a cleaning apparatus for cleaning exterior walls such as glass and exterior surfaces in a building including a high-rise building. In this manner, it is very important to reduce the amount of the cleaning liquid used in cleaning the cleaning liquid by spraying the cleaning liquid onto the exterior wall of the building and scraping the cleaning liquid with the wiper member. The cleaning liquid is provided in the main body of the cleaning device in a container. The larger the cleaning liquid required for cleaning, the larger the cleaning liquid container becomes, and the body of the cleaning liquid container becomes larger. As the main body becomes larger, the influence of the wind and the like becomes greater. When the weight of the main body is increased, the possibility that the glass breaks or the outer wall surface of the building is damaged when the cleaning device is shaken due to the wind, The risk increases. The cleaning device is provided with a waste cleaning solution collection structure to recover the waste cleaning solution so that the waste cleaning solution sprayed on the outer wall surface of the building is not dropped by the wiper member. If the amount of the cleaning solution sprayed on the outer wall surface of the building is large for cleaning, The amount of the waste liquid washing liquid is increased and the size of the waste liquid washing liquid collecting structure is also increased. This increases the installation cost as well as the weight of the main body, which increases the risk of the cleaning work . Therefore, it is necessary to develop a new technology that can reduce the amount of cleaning solution while improving cleaning efficiency.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby. In particular, the term "exterior wall surface" is used herein to refer to the exterior wall surface of a building, but to include the windows of a building.

FIG. 1 is a schematic perspective view showing a configuration of a washing liquid distributing apparatus 1 according to an embodiment of the present invention. In FIG. 2, a rotating body 20 is formed as a pin- FIG. 2 is a schematic perspective view corresponding to FIG. 1 showing a cleaning liquid dispensing apparatus according to another embodiment of the present invention. Referring to FIG.

1 and 2, the cleaning liquid distributing apparatus 1 according to the present invention is arranged such that the cleaning liquid distributing apparatus 1 is disposed so as to cross the direction in which the cleaning liquid distributing apparatus 1 moves vertically, A vertical drop nozzle 11 for vertically dropping the cleaning liquid in the rotary body 10 and a vertical drop nozzle 11 for containing the cleaning liquid, And a cleaning liquid container 12 for supplying a cleaning liquid.

Specifically, the rotating body 10 is a disc-shaped member, and is a member that is horizontally arranged to rotate and is disposed orthogonally to the outer wall surface of the building in front of the outer wall surface of the vertical building. In this case, the rotary shaft (not shown) of the rotary body 10 is positioned in the vertical direction in parallel with the outer wall surface of the building. For the sake of explanation, in the present specification, it is described that the rotating body 10 is arranged horizontally so as to be orthogonal to the outer wall surface of the building, it does not mean that the rotating body 10 is orthogonal at an angle of exactly 90 degrees, The whole body 10 is disposed so as to cross the direction in which the washing liquid distributing apparatus 1 is vertically moved, and the portion of the rotating body 10 facing the outer wall surface of the body is vertically upwardly or slightly inclined downward And the like.

Although not shown in the drawing, the rotating body 10 is rotated by a rotation driving device such as a motor. In the embodiment shown in FIG. 1, the rotator 10 may be in the form of a brush, not a disc. In other words, the rotating body 10 may be constituted by a rotating brush extending in the radial direction from the rotating shaft of the brush. However, as in the embodiment shown in FIG. 2, one or a plurality of rotating blades (pins) The rotating body 10 may be formed.

When the cleaning liquid drops vertically from the vertical drop nozzle 11 onto the upper surface of the rotating body 10 as described later, the rotating body 10 collides with the rotating body 10 rotating, By the rotation of the whole body (10), the washing liquid is scattered in the direction toward the outer wall surface of the building. That is, the cleaning liquid collides with the rotating body 10 rotating while being vertically dropped, and is scattered toward the outer wall surface of the building.

The vertical falling nozzle 11 is a member for supplying the cleaning liquid contained in the cleaning liquid container 12 in a state of vertically falling onto the upper surface of the rotating body 10. The supply amount of the cleaning liquid supplied to the vertical drop nozzle 11 is adjusted between the vertical drop nozzle 11 and the cleaning liquid container 12 so that the amount and shape of the cleaning liquid fall down from the vertical drop nozzle 11 A control valve 13 may be provided. In order to clean the outer wall surface of the building, it may suffice to drop in the form of a droplet, that is, a drop when the cleaning liquid drops onto the upper surface of the rotator 10. The control valve 13 controls the cleaning liquid so that the cleaning liquid drops from the vertical dropping nozzle 11 as necessary. Of course, it is also possible to adjust the size of the nozzle hole of the vertical drop nozzle 11 without adjusting the valve 13 so that the cleaning liquid drops from the vertical drop nozzle 11 into the droplet shape.

3 is a schematic perspective view of a building exterior wall cleaning apparatus 100 (abbreviated as "cleaning apparatus 100" throughout the present specification) according to the present invention, and FIG. 4 is a schematic perspective view of the present invention Sectional side view taken along the line AA of FIG. 3 showing a state in which the cleaning apparatus 100 of the present invention is installed and cleaned against the exterior wall surface of the building. 1 and 2, the cleaning liquid dispensing apparatus 1 according to the present invention may be provided in the cleaning apparatus 100 for cleaning while descending along the outer wall surface of the building in a state of facing the outer wall surface of the building. The cleaning apparatus 100 is provided with a main body 101 on which various components such as a member for collecting a waste washing liquid and a motor for driving the wiper member 102 are installed. 1 is provided in the main body 101. The vertical drop nozzle 11 is provided in a state protruding from the front surface of the main body 101 (the surface facing the outer wall surface of the building) 10 is rotatably provided in an opening formed in the front surface of the main body 101 at a position vertically below the vertical falling nozzle 11.

Therefore, although not shown, a rotation shaft and a rotation driving device for rotating the rotating body 10 are installed in the main body 101. In particular, the cleaning device 100 may include two rotating bodies 100 as illustrated in FIG. 3, but may include a plurality of three or more rotating bodies 100, 100 may be provided. A wiper member 102 for scraping the cleaning liquid and cleaning the exterior wall surface of the building exists above the vertical drop nozzle 11. As shown in the figure, the wiper member 102 may be provided on the body 101, (Not shown). Although not shown in the drawing, the main body 101 may be further provided with a structure capable of collecting the waste washing liquid at a position lower than the rotating body 10.

As described above, the cleaning apparatus 100 equipped with the cleaning liquid distributing apparatus 1 according to the present invention is cleaned by moving downward along the outer wall surface of the building by a cable hanging down from the roof of the building. As described above, when the cleaning liquid supplied from the cleaning liquid container 12 is vertically dropped onto the upper surface of the rotating body 10 through the vertical drop nozzle 11, the cleaning fluid collides with the rotating body 10, 10 are in a rotating state, the cleaning liquid impinging on the rotating body 10 is scattered in the direction toward the outer wall surface of the building. When the cleaning liquid is scattered on the outer wall surface of the building by the rotating body 10, the cleaning device 1 descends and the wiper member 102 scratches the cleaning liquid to clean foreign materials on the exterior wall surface of the building. In the case of a spray nozzle used in a conventional cleaning apparatus, since a cleaning liquid must be injected toward the outer wall surface of the building by applying pressure, a member for forming a pressure is required, and a considerable amount of the cleaning liquid is used. In other words, when the cleaning liquid is very small, it is not sprayed onto the outer wall surface of the building, and even if it is sprayed, the area where the cleaning liquid is sprayed is very narrow.

However, in the present invention, since the cleaning liquid is scattered by the collision with the rotating body 10, a very small amount of the cleaning liquid falling into the rotating body 10 in the form of water droplets is sufficient. That is, even a small amount of cleaning liquid, such as a water droplet, collides with the rotating body 10 and is scattered widely on the outer surface of the building due to the impact. Therefore, according to the present invention, it is possible to wet the exterior wall surface of the building and to easily clean the exterior wall surface even when only a much smaller amount of cleaning liquid is used than in the case of using the conventional pressurizing spray nozzle.

As described above, according to the present invention, the cleaning liquid for cleaning the outer wall surface of the building can be effectively scattered on the outer wall surface of the building even in a small amount, and the amount of the cleaning liquid used for cleaning can be remarkably reduced. The amount of the cleaning liquid required for cleaning can be reduced so that the configuration for collecting the waste liquid cleaning liquid can be omitted or reduced and the size of the cleaning liquid container can be reduced as well as the weight of the cleaning liquid to be loaded on the cleaning device 100 is reduced, It is possible to effectively prevent the cleaning device from shaking greatly or hitting against the outer wall surface of the building when the cleaning operation is performed.

5 and 6 are views corresponding to Fig. 4, respectively, showing an embodiment (Fig. 5) in which the front portion of the rotating body 10 facing the outer wall surface of the building is inclined upward, And the front portion facing the surface is inclined downward. As described above, when the rotating body 10 is described in the present specification including the claims, it is arranged horizontally so as to be orthogonal to the outer wall surface of the building ", but it means only horizontally at an angle of exactly 90 degrees And the rotating body 10 may be inclined vertically upward so that a portion of the rotating body 10 facing the outer wall surface of the building is lifted up as shown in FIG. 5, and as shown in FIG. 6, The term "horizontal" in the description of the arrangement of the rotating body 10 is not limited to the state as shown in Fig. 4, And the state shown in Fig. 6. [0064] When the rotating body 10 is inclined as described above, the effect that the area in which the washing liquid is scattered is increased, The.
