Description

[Technical Field]

[0001] The present invention relates to a device that cleans the surfaces of walls, roofs, roads, solar panels, and other objects that require cleaning by brushing with a rotating brush and spraying ultra-fine bubble water onto the surface of the object. [Background technology]

[0002] In all kinds of structures, such as ordinary homes, industrial facilities, and monuments, there is a need to clean the surfaces of these structures and keep them clean. However, if cleaning agents such as surfactants are used to clean the surfaces of these objects, they can provide sufficient cleaning power, but they place a heavy burden on the natural environment. On the other hand, if a liquid agent with low cleaning effectiveness is used in order to prioritize environmental friendliness, there is also the problem that sufficient cleaning power cannot be achieved.

[0003] Therefore, a method using a liquid containing fine bubbles has been proposed as a method that can thoroughly clean the surface of an object while being considerate of the natural environment. Japanese Patent Publication No. 6780172 (see Patent Document 1) proposes a cleaning method using an aqueous detergent characterized by containing (a) diethylene glycol monoalkyl ether, (b) tertiary amine, (c) lactic acid ester, (d) hydroxycarboxylic acid, and (e) water. This aqueous detergent exhibits high cleaning performance despite being substantially free of surfactants, and can effectively remove various types of dirt without causing adverse effects due to residual surfactants. Furthermore, this aqueous detergent uses lactic acid ester, which has a relatively low impact on the human body, and therefore has the advantage of being easy to handle and dispose of.

[0004] As examples of cleaning water containing ultrafine bubbles and a method for cleaning the surface of an object using said cleaning water, Japanese Patent Application Laid-Open No. 2021-049490 (see Patent Document 2) proposes a cleaning water manufacturing method and cleaning water spraying system, which include a first step of bubbling soft water Ws to produce soft water Wp containing fine bubbles, and a second step of electrolyzing the soft water to obtain cleaning water Wm containing a mixture of ozone bubbles and fine bubbles having a concentration of 1 ppm or more in the soft water.

[0005] However, even with these technologies, it is still difficult to achieve both environmental friendliness and sufficient cleaning of object surfaces, and there is a demand for cleaning devices with even higher cleaning capabilities while still being environmentally friendly.

[0007] The problem that the present invention aims to solve is to provide an object surface cleaning device that has high cleaning capabilities by using ultra-fine bubbles and a rotating brush, without using cleaning agents that have a high environmental impact. [Means for solving the problem]

[0008] As a means for solving the above-mentioned problems, the object surface cleaning device of the present invention is an object surface cleaning device comprising a long rod section incorporating a flow path for cleaning water, an oscillating section provided at one end of the long rod section, a rotating brush section detachably attached to the oscillating section, a connection section provided at the other end of the long rod section, a water flow adjustment switch attached at a predetermined position on the long rod section, an ultrafine bubble generator attached at a predetermined position on the long rod section, and a water pressure adjustment valve attached to the rotating brush section, wherein the object surface cleaning device is connected via the connection section to tap water, a river pump, a water storage tank, or other cleaning water supply means, and the cleaning water supplied to the long rod section from the cleaning water supply means has ultrafine bubbles added to it via the ultrafine bubble generator as it passes through the flow path, and is then sprayed onto the object surface from the rotating brush section.

[0009] In the object surface cleaning device of the present invention, the rotating brush unit is characterized by comprising one or more disk-shaped brushes.

[0010] In the object surface cleaning device of the present invention, the rotating brush unit is characterized by comprising one or more cylindrical brushes.

[0011] In the object surface cleaning device of the present invention, the brush has bristles at the tips thereof which are thinner than the bristles themselves.

[0012] In the object surface cleaning device of the present invention, the bristles constituting the brush are arranged such that hard bristles and soft bristles are alternately arranged at predetermined intervals.

[0013] The effects of the object surface cleaning device of the present invention include the following. (1) By using ultra-fine bubble water, which is made up of ultra-fine bubbles, sufficient cleaning power can be achieved due to the effect of the ultra-fine bubbles. (2) By using ultra-fine bubble water, which is made up of ultra-fine bubbles, there is no physical burden on the object being cleaned, and there is no need to use cleaning agents that have a large environmental impact, such as surfactants and snow-melting agents, making it environmentally friendly and not damaging to the natural environment. (3) When the cleaning water is sprayed onto the surface of an object from the rotating brush unit, the force of the spray onto the object surface can be adjusted using the water pressure adjustment valve. By spraying cleaning water at high water pressure onto a heavily soiled object surface, ultrafine bubbles are generated when the cleaning water collides with the surface of the object, so even heavily soiled objects can be thoroughly cleaned. (4) By forming ultra-fine bristles at the tip of the rotating brush, the brush can penetrate into minute irregularities and gaps on the surface of objects, providing greater cleaning performance. (5) By arranging the bristles of the rotating brush part alternately between hard and soft bristles at a predetermined interval, it is possible to remove dirt from the surface of an object regardless of the type of dirt, and it is possible to demonstrate a higher cleaning ability.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The object surface cleaning device of the present invention will be described in detail with reference to the drawings. 1 and 2 show a first embodiment of the object surface cleaning device of the present invention, in which an object surface cleaning device 11 is used to spray ultra-fine bubble water 12 onto the surface of an object to perform cleaning. At this time, the high cleaning ability of the ultra-fine bubbles contained in the ultra-fine bubble water 12 allows the surface of the object to be cleaned easily and thoroughly. In addition, the object surface cleaning device 11 has a rotating brush unit 31 at the tip of its long rod unit 21, and the cleaning by spraying the ultra-fine bubble water 12 and the cleaning by brushing with the rotating brush unit 31 create a synergistic effect, allowing it to demonstrate extremely high cleaning ability.

[0016] Taking into consideration the physical load on the surface of the object to be sprayed and the environmental load due to the outdoor environment, the ultra-fine bubble water 12 is preferably obtained by adding ultra-fine bubbles with extremely small diameters to pure water, which is highly pure water that contains almost no or no impurities. The pure water may be distilled water, deionized water, or the like, from which impurities have been sufficiently removed, and even tap water may be used as pure water after being filtered. The diameter of the ultrafine bubbles contained in the pure water is preferably less than 100 μm, and in particular, ultrafine bubbles having a diameter of less than 1 μm (so-called ultrafine bubbles) can be suitably used. In addition, by appropriately selecting the most effective diameter of the ultrafine bubbles according to the shape, structure, material, etc. of the object to be cleaned, high cleaning performance can be always achieved regardless of the nature of the object to be cleaned.

[0017] As shown in Figures 1 and 2, the object surface cleaning device 11 of the present invention comprises a long rod portion 21 incorporating a flow path (not shown) for cleaning water, a swivel portion 22 provided at one end of the long rod portion 21, a rotating brush portion 31 detachably attached to the swivel portion 22, a connection portion 23 provided at the other end of the long rod portion 21, a water flow adjustment switch 41 attached at a predetermined position on the long rod portion 21, an ultrafine bubble generator 51 attached at a predetermined position on the long rod portion 21, and a water pressure adjustment valve 32 attached to the rotating brush portion 31.

[0018] The object surface cleaning device 11 is connected to tap water, a river pump, a water tank, or other cleaning water supply means (not shown) via the connection part 23, and the cleaning water supplied from the cleaning water supply means to the long rod part 21 has ultrafine bubbles added to it via the ultrafine bubble generator 51 as it passes through the flow path, and is then sprayed onto the object surface from the rotating brush part 31.

[0019] In this way, regardless of the means for supplying cleaning water, in any environment, by connecting the means for supplying cleaning water to the connection part 23 of the object surface cleaning device 11 via, for example, a hose, cleaning water can be sprayed from the water pressure adjustment valve 32 of the rotating brush part 31, and the combination of cleaning by brushing with the rotating brush part 31, cleaning by spraying the cleaning water, and the cleaning power of the ultra-fine bubbles added to the cleaning water can demonstrate extremely high cleaning ability.

[0020] The long rod portion 21 has a built-in flow path for cleaning water (not shown) inside, and is provided with a swinging portion 22 at one end and a connection portion 23 at the other end. Also, attached to predetermined positions on the long rod portion 21 are a water flow adjustment switch 41 for the cleaning water flowing in the flow path, and an ultrafine bubble generator 51 for adding ultrafine bubbles to the cleaning water. Furthermore, the long rod portion 21 may have an extension and contraction function (not shown) that allows it to be extended and contracted as needed.

[0021] The rotary brush unit 31 includes the water pressure adjusting valve 32 and is detachably attached to the oscillating unit 22 . By swinging the rotary brush unit 31 via the swing unit 22, cleaning work can be performed regardless of the positional relationship between the worker and the surface of the object. In addition, cleaning water is sprayed onto the surface of the object from the water pressure regulating valve 32 of the rotating brush unit 31, and by adjusting the water pressure regulating valve 32, the water pressure at the time of spraying the cleaning water can be adjusted according to the degree of dirt on the surface of the object.

[0022] With this configuration, if the object surface is heavily soiled, the water pressure regulating valve 32 can be adjusted to increase the water pressure when the wash water is sprayed, and when the wash water collides with the object surface, the force of the water pressure and the ultra-fine pores that are further created by the collision with the object surface allow the wash water itself to provide a high cleaning effect. Also, if the object surface is only lightly soiled or if the condition of the object surface makes it undesirable to spray wash water at high water pressure, the water pressure regulating valve 32 can be adjusted to lower the water pressure when the wash water is sprayed, and the water pressure regulating valve 32 allows for efficient cleaning work.

[0023] The water flow adjustment switch 41 is a switch that changes the strength of the water flow of the wash water flowing through the flow path, and by using it in combination with the water pressure adjustment valve 32, it is possible to finely adjust the force and water pressure of the wash water sprayed from the water pressure adjustment valve 32. In addition, the water flow adjustment switch 41 may be provided with a switch that adjusts the rotation speed of the brush of the rotating brush unit 31.

[0024] The ultrafine bubble generator 51 is a device that adds ultrafine bubbles to the cleaning water as it passes through the ultrafine bubble generator 51, and its internal structure (not shown) may include, for example, a plurality of protrusions and small holes.

[0025] In this embodiment, the rotating brush section is two disk-shaped brushes 31a, but it goes without saying that one or more brushes may be selected and applied as appropriate depending on the site conditions and the object to be cleaned. 3 and 4, the rotating brush unit 71 equipped with a cylindrical brush can be used in place of the rotating brush unit 31. The rotating brush unit 71 is also equipped with the water pressure adjustment valve 32. Although the rotating brush unit 71 is shown equipped with one cylindrical brush in FIGS. 3 and 4, it goes without saying that one or more brushes can be selected and applied as appropriate depending on the conditions of the site where cleaning is performed and the object to be cleaned.

[0026] 5 is a schematic enlarged view of the tip portion of the bristles 81 that constitute the brush of the rotating brush unit 31, 71. As shown in the figure, the bristles 81 may have a plurality of ultra-fine bristles 82 formed at the tip thereof, the bristles 82 being thinner than the bristles 81 themselves. By configuring it in this way, the bristles can penetrate into minute recesses on the surface of the object, thereby achieving a sufficient cleaning effect.

[0027] As shown in FIGS. 6 and 7, the bristles 81 constituting the brush of the rotary brush unit 31, 71 may be arranged such that hard bristles 91 and soft bristles 92 are alternately arranged at predetermined intervals. With this configuration, a single rotating brush unit can provide sufficient cleaning performance regardless of the degree of soiling of the object surface, without the need to replace the rotating brush unit.

[0028] A camera unit (not shown) capable of photographing the surface condition of the target object may be attached to the rotary brush unit 31, 71. By constantly checking the shape of the target object surface and the cleaning status through the camera unit, work can be performed accurately and efficiently.

[0029] In this way, with the object surface cleaning device of the present invention, even when a worker performs the cleaning work, sufficient cleaning power can be exerted by combining cleaning by brushing with the rotating brush unit, cleaning by spraying cleaning water, the cleaning ability of the ultrafine bubbles added to the cleaning water via the ultrafine bubble generator, and the cleaning ability of the ultrafine bubbles further generated when the cleaning water collides with the object surface.In addition, by using ultrafine bubble water made of pure water and ultrafine bubbles, there is no physical burden on the object to be cleaned, and it is possible to eliminate the need for cleaning agents that have a large environmental impact, such as surfactants and snow-melting agents, making it environmentally friendly and not damaging the natural environment. [Industrial Applicability]

[0030] The object surface cleaning device of the present invention can be applied to cleaning all kinds of object surfaces, and since it does not require the use of detergents such as surfactants that place a heavy physical burden on the equipment and a heavy burden on the surrounding natural environment, it can be used with any equipment and does not harm the surrounding natural environment.
