Description

Technology Field

[0001] More specifically, the present invention uses steam to easily clean stubborn stains on windows.

[0002] This relates to a steam-type window cleaning device capable of removing dust. Background Technology

[0004] Due to the trend of increasing apartment height, it is impossible to clean the exterior surfaces of windows on the upper floors of newly constructed buildings. In some cases, apartment management offices conduct water cleaning of the entire building's exterior walls through a bidding process, which includes cleaning the window exteriors; however, this is not frequently carried out due to budgetary constraints.

[0005] Among the prior art for cleaning windows, etc., Patent Registration No. 10-1059695, a 'steam-type window cleaning device' is disclosed.

[0006] In the case of the aforementioned prior art, although it has a steam generating unit for generating steam, it has the limitation of mainly cleaning only the inner surface of windows inside a building, and therefore cannot resolve the problem raised in the present invention.

[0007] In contrast, Korean Patent Registration No. 10-1188424, a ‘window cleaning device,’ is also disclosed and presents a configuration for simultaneously cleaning the inner and outer surfaces of a window by providing an inner cleaner and an outer cleaner.

[0008] However, even in the case of these prior art documents, when cleaning apartment living room windows, the size of most apartment living room windows is inevitably substantial. Furthermore, when operating inner and outer cleaning units that move simultaneously along the inner and outer surfaces of the window from within the living room, complete cleaning is difficult due to the limitations of the connecting hose. Moreover, if the attachment of the inner and outer cleaning units is compromised due to external conditions, there is a risk that the outer cleaning unit may fall out of the window, causing unforeseen damage to the floor below.

[0009] In addition, Korean Utility Model Registration No. 20-283646, 'Window cleaner of a steam cleaner set,' is disclosed, but it has limitations in mainly cleaning the inner surface of the window, so it cannot solve the problem raised in the present invention. Prior art literature

[0026] According to the present invention, the stubborn dirt on the outer surface of windows of high-rise buildings, such as apartments, can be easily removed by steam cleaning.

[0027] In addition, since the present invention cleans the exterior surface of the window using steam, there is no need for a separate cleaning process by spraying water. This eliminates the need for a separate process to remove cleaning solution or moisture remaining on the window surface after spraying, as was the case with conventional methods, allowing the cleaning process to be performed very easily and conveniently.

[0034] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] As shown in the attached drawings, the present invention provides a steam cleaning device for the exterior of a building window, such as an apartment, configured to enable cleaning by operation from inside, thereby ensuring operational safety.

[0037] To this end, the present invention, as shown in FIG. 1,

[0038] It may be composed of a rail (100), a rack (200) provided along the rail (100), a first motor (300), a moving frame (400), a second motor (500), a nozzle arm (600), a nozzle (610), and a steam generator (700).

[0040] The above rail (100) is provided on the outer side of a building such as an apartment and is provided so as to be detachably attached to the upper surface of an outer frame (20) to prevent safety accidents such as a resident falling outside after the window (10) is opened.

[0041] The above rail (100) is provided on the upper side of the aforementioned outer frame (20) and is fixed by a band (110) or the like so as to be detachable. At this time, it is preferable that the band (110) connects and fixes the outer frame (20) at both ends of the rail (100).

[0042] It is preferable that the rail (100) be configured to be fixed between the two ends of the rail (100) and the outer frame (20) by a band (110) for easy attachment and detachment from the outer frame (20), and it is also possible to configure it so that it can be fixed and separated by substituting other components other than the band (110).

[0043] Meanwhile, a rack (200) fixed along the front side of the above rail (100) is provided.

[0044] As shown in the drawing, the above rack (200) is configured to be formed with a length corresponding to the length of the rail (100).

[0045] A first motor (300) equipped with a pinion (310) that is geared with the rack (200) is fixed to one side of a movable frame (400).

[0046] As shown in the drawing, the above-mentioned moving frame (400) has an L-shape extending from the upper surface of the rail (100) to the side of the rail (100).

[0047] In such a moving frame (400), the part located on the upper side of the rail (100) is called the horizontal moving frame (410), and the part that is bent vertically and connected from thereis is called the vertical moving frame (420).

[0048] The first motor (300) is fixed to the outer surface of the vertical moving frame (420), and the pinion (310) is positioned on the inner surface of the vertical moving frame (420) and connected to the shaft (not shown in the drawing) of the first motor (300).

[0049] Meanwhile, in order to facilitate the movement of the above-mentioned moving frame (400) along the rail (100), it is preferable to configure a moving guide (411) on the bottom side of the horizontal moving frame (410) of the moving frame (400).

[0050] With the configuration of the moving frame (400) and the first motor (300) as described above, when the first motor (300) is driven, it becomes possible to move back and forth along the rack (200) which is geared with the pinion (310) by the rotation of the pinion (310).

[0051] Meanwhile, a second motor (500) is provided on the upper side of the above-mentioned moving frame (400).

[0052] As shown in the drawing, the second motor (500) has a configuration in which it is fixed to the outer surface of a vertical frame (510) that is vertically connected from a horizontal moving frame (410) of a moving frame (400).

[0053] Meanwhile, the nozzle arm (600) that rotates left and right according to the driving of the second motor (500) is connected, and the nozzle (610) is configured on the upper side of the nozzle arm (600).

[0054] It is configured so that steam is sprayed through the nozzle (610), and steam generated from a separately provided steam generator (700) is configured to be sprayed toward the nozzle (610) through the nozzle arm (600).

[0055] In addition, the nozzle arm (600) comprises an inlet / outlet nozzle arm (620) that extends from the nozzle arm (600) to ensure length adjustment variability, and is equipped with a screw shaft (630) connected to the inlet / outlet nozzle arm (620), and is equipped with a third motor (800) on the outside of the nozzle arm (600) to rotate the screw shaft (630).

[0056] Meanwhile, it goes without saying that the nozzle (610) described above must be provided at the end of the nozzle arm (620) that is extended and pulled in and out by the nozzle arm (600).

[0057] The steam generated from the steam generator (700) is configured to be supplied to the nozzle (610) through the hose (611).

[0059] Meanwhile, steam supplied through the nozzle (610) provided at the end of the inlet / outlet nozzle arm (620) of the nozzle arm (600) must be supplied over the entire surface area of ​​the window (10).

[0060] That is, the nozzle (610) must be positioned evenly across the entire area from the corner area (A) of the window (10) to the horizontal side area (B) of the moving frame (400), and steam must be supplied.

[0061] To this end, in the present invention, it is preferable to configure the inlet / outlet nozzle arm (620) of the nozzle arm (600) to be extended or retracted according to the driving of the third motor (800) as described above, so that steam injection supply is provided while the position of the nozzle (610) is variable.

[0062] The steam injection position setting is configured such that the maximum distance point is set to the corner area (A) by zeroing the nozzle (610). In this way, the position setting value of the edge area (B), which is the shortest distance point from the corner area (A), which is the maximum distance point, is initially input, and the position setting value of the lower corner area (C), which corresponds to the left and right corner parts of the window area on the lower side of the rail (100), is also initially input. It is preferable to have a control unit (900) for controlling the inflow / outflow distance of the nozzle arm (620) from the nozzle arm (600) according to the movement of the moving frame (400).

[0064] According to the configuration of the present invention, the operator fixes and installs the rail (100) constituting the present invention on the upper surface of the outer frame (20) forming the railing of the apartment living room using a band (110), etc., then drives the first motor (300) to the center of the rail (100) to position it in the center, drives the second motor (500) so that the position of the nozzle arm (600) is directed toward the corner area (A) of the window (10), and then drives the third motor (800) so that the inlet / outlet nozzle arm (620) is pulled out, thereby positioning the nozzle (610) provided at the end of the inlet / outlet nozzle arm (620) in the corner area (A).

[0065] As the nozzle (610) is positioned in the corner area (A) in this manner, the withdrawal length of the inlet / outlet nozzle arm (620) is zeroed and input to the control unit (900).

[0066] In addition, the withdrawal length of the inlet / outlet nozzle arm (620) at the point where the nozzle (610) is positioned from the center of the rail (100) toward the side of the variation area (B) is also checked and input to the control unit (900), and likewise, the withdrawal length of the inlet / outlet nozzle arm (620) at the point where it is positioned toward the lower corner area (C) is also checked and input to the control unit (900).

[0067] In this way, after the position values ​​of the corner area (A) and bottom corner area (C) corresponding to the longest distance point from the center of the rail (100) and the side area (B) corresponding to the shortest distance point are set and input to the control unit (900), the second motor (500) and the third motor (800) are driven so that the position of the nozzle (610) is positioned at the corner area (A) corresponding to the longest distance point.

[0068] From the point when the nozzle (610) is positioned in the corner area (A), steam is supplied through the hose (611) connected to the nozzle (610) according to the operation of the steam generator (700) under the control of the control unit (900), and the process of cleaning the outer surface of the window (10) through the nozzle (610) is performed.

[0069] In this way, steam is supplied through the nozzle (610) starting from the corner area (A), and the outer surface of the window (10) is cleaned by the nozzle arm (600) rotating according to the drive of the second motor (500) and displacing the position of the nozzle (610) as it passes through the corner area (A) and extends to the change area (B) and the bottom corner area (C).

[0070] As the nozzle arm (600) rotates up and down according to the operation of the second motor (500), the moving frame (400) moves back and forth along the rail (100) by the operation of the first motor (300) mentioned above, and additionally, as the position of the nozzle (610) is adjusted by the position variation of the inlet / outlet nozzle arm (620) by the operation of the third motor (800), the steam sprayed through the nozzle (610) is evenly sprayed over the entire surface of the outer side of the window (10), making cleaning possible.

[0071] High-temperature steam sprayed by the nozzle (610) is sprayed at high pressure onto the surface of the window (10), and since it removes all dust and foreign substances attached to the surface and dries it at the same time, the process of spraying a cleaning solution or wiping off the cleaning solution again, as in the past, becomes unnecessary, making it possible to clean the outer surface of the apartment window with a simple configuration.

[0072] In addition, it would be desirable to install a safety net (40) at the bottom of the outer frame (20) to prevent safety accidents that may occur when unexpected falling objects fall downward.

[0074] As described above, although the present invention has been explained by limited embodiments and drawings, the present invention is not limited to the above embodiments, and it is obvious that various modifications and variations from the description above may be possible by those skilled in the art to which the present invention belongs.

[0075] Therefore, the technical concept of the present invention should be understood by the claims set forth below, but it is obvious that all equivalent or equivalent variations thereof fall within the scope of the technical concept of the present invention. Explanation of the symbols
