Description

Technical Field

[0001] The present invention relates to an apparatus for cleaning the surfaces of walls, roofs, road surfaces, solar panels, and other objects that require cleaning, by brushing with a rotary brush and spraying ultrafine air bubbles onto the object surfaces.

Background Art

[0002] In all structures such as ordinary houses, industrial facilities, monuments, etc., it is required to clean the surfaces of the objects including the structures and keep them in a clean state. However, when cleaning the surface of the object using a cleaning agent such as a surfactant, although sufficient cleaning ability can be exhibited, the load on the natural environment is high. On the other hand, when giving priority to consideration for the natural environment and using a liquid agent with low cleaning effect, there is also a problem that sufficient cleaning ability cannot be exhibited.

[0003] Therefore, as a method capable of sufficiently cleaning the object surface while considering the natural environment, a method using a liquid containing fine bubbles has been proposed. In Japanese Patent No. 6780172 (see Patent Document 1), as an aqueous cleaning agent, it is characterized by containing (a) diethylene glycol monoalkyl ether, (b) a tertiary amine, (c) a lactate ester, (d) a hydroxycarboxylic acid, and (e) water. Although such an aqueous cleaning agent substantially does not contain a surfactant, it can exhibit high cleaning performance. Therefore, various stains can be suitably removed without causing an adverse effect due to the residue of the surfactant. Further, since this aqueous cleaning agent uses a lactate ester that has relatively little influence on the human body, a cleaning method using an aqueous cleaning agent characterized by also having the advantage of being easy to handle and dispose of has been proposed.

[0004] As a method for producing cleaning water containing ultrafine bubbles and a method for cleaning the surface of an object using the cleaning water, Japanese Patent Publication No. 2021-049490 (see Patent Document 2) proposes a method for producing cleaning water Wm that is sprayed onto equipment T in a toilet and used for cleaning therein. This method includes 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 in which ozone bubbles and fine bubbles with a concentration of 1 ppm or more are mixed in the soft water.

[0005] However, even with these technologies, it remains difficult to achieve both environmental considerations and thorough cleaning of object surfaces. There is a need for cleaning equipment with even higher cleaning capabilities while still prioritizing environmental considerations. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Patent No. 6780172 [Patent Document 2] Japanese Patent Publication No. 2021-049490 [Patent Document 3] Japanese Patent Publication No. 2013-139958 [Overview of the project] [Problems that the invention aims to solve]

[0007] Therefore, the problem that this invention aims to solve is to provide an object surface cleaning device that does not use environmentally harmful cleaning agents and has high cleaning capacity by using ultrafine bubbles and a rotating brush. [Means for solving the problem]

[0008] As a means to solve the above-mentioned problems, the object surface cleaning apparatus of the present invention comprises a long rod section containing a flow path for cleaning water, a swivel section provided at one end of the long rod section, a rotating brush section detachably attached to the swivel section, a connecting 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 generating device 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 apparatus is connected via the connecting section to tap water, a river pump, a water storage tank, or other means of supplying cleaning water, and the cleaning water supplied from the cleaning water supply means to the long rod section has ultrafine bubbles added to it via the ultrafine bubble generating device as it passes through the flow path, and is sprayed onto the object surface from the rotating brush section.

[0009] Furthermore, the object surface cleaning apparatus of the present invention is characterized in that the rotating brush section consists of one or more disc-shaped brushes.

[0010] Furthermore, the object surface cleaning apparatus of the present invention is characterized in that the rotating brush section consists of one or more cylindrical brushes.

[0011] Furthermore, the object surface cleaning apparatus of the present invention is characterized in that ultrafine bristles, thinner than the thickness of the bristles, are formed at the tips of the bristles constituting the brush.

[0012] Furthermore, the object surface cleaning apparatus of the present invention is characterized in that the bristles constituting the brush are arranged alternately with hard bristles and soft bristles at predetermined intervals.

[0013] The effects and benefits of the object surface cleaning apparatus of the present invention include the following: (1) By using ultrafine bubble water, which consists of ultrafine bubbles, sufficient cleaning power can be achieved through the effect of the ultrafine bubbles. (2) By using ultrafine bubble water, which consists of ultrafine bubbles, there is no physical burden on the object being cleaned, and it does not require the use of environmentally harmful cleaning agents such as surfactants and de-icing agents, making it environmentally friendly and not damaging to the natural environment. (3) When spraying cleaning water from the rotating brush section onto the object surface, the force of the spray of cleaning water onto the object surface can be adjusted by the water pressure adjustment valve. By spraying cleaning water at a high water pressure onto heavily soiled object surfaces, ultrafine bubbles are generated as the cleaning water collides with the object surface, allowing even heavily soiled surfaces to be thoroughly cleaned. (4) By forming ultra-fine bristles at the tips of the brushes in the rotating brush section, the brush can get into even the smallest irregularities and gaps on the surface of an object, thereby achieving higher cleaning performance. (5) By arranging hard and soft bristles alternately at predetermined intervals in the rotating brush section, dirt of any type can be removed from the surface of the object, resulting in higher cleaning performance.

Embodiments for Carrying Out the Invention

[0015] The object surface cleaning device of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 2 show a first embodiment of the object surface cleaning device of the present invention. Using the object surface cleaning device 11, ultrafine air bubbles 12 can be injected onto the object surface for cleaning. At this time, due to the high cleaning ability of the ultrafine air bubbles contained in the ultrafine air bubbles 12, the surface of the object surface can be easily and sufficiently cleaned. Furthermore, the object surface cleaning device 11 is equipped with a rotating brush section 31 at the tip of its long rod section 21, and the cleaning by spraying the ultrafine bubble water 12 and the cleaning by brushing with the rotating brush section 31 work in synergy to achieve extremely high cleaning performance.

[0016] The ultrafine bubble water 12 is preferably obtained by incorporating ultrafine bubbles with extremely small diameters into pure water, which is water of high purity that contains little to no impurities, taking into consideration the physical load on the surface of the object to be sprayed and the environmental load due to it being basically an outdoor environment. The aforementioned pure water can be any water from which impurities have been sufficiently removed, such as distilled water or deionized water, and even tap water can 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 ultrafine bubbles of less than 1 μm (so-called ultra-ultrafine bubbles) can be used particularly favorably. Furthermore, by appropriately selecting and using the most effective diameter of the ultrafine bubbles according to the shape, structure, and material of the object to be cleaned, it is possible to consistently achieve high cleaning performance regardless of the properties of the object being cleaned.

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

[0018] The object surface cleaning device 11 is connected via the connection part 23 to tap water, a river pump, a water storage tank, or other means of supplying cleaning water (not shown). 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 generating device 51 as it passes through the flow path, and is then sprayed onto the object surface from the rotating brush part 31.

[0019] Thus, regardless of the means by which the cleaning water is supplied, in any environment, by connecting the means by which the cleaning water is supplied to the connection part 23 of the object surface cleaning device 11, for example via a hose, the cleaning water can be sprayed from the water pressure regulating valve 32 of the rotating brush part 31. The cleaning by brushing of the rotating brush part 31, the cleaning by spraying the cleaning water, and the cleaning power of the ultrafine bubbles added to the cleaning water combine to exhibit extremely high cleaning ability.

[0020] The long rod section 21 has a built-in flow path (not shown) for cleaning water, with a swivel section 22 at one end and a connection section 23 at the other end. A water flow adjustment switch 41 for the cleaning water flowing through the flow path and an ultrafine bubble generator 51 for adding ultrafine bubbles to the cleaning water are attached to predetermined positions on the long rod section 21. Furthermore, the long rod portion 21 may be equipped with an extendable / retractable function (not shown) that allows it to extend or retract as appropriate.

[0021] The rotating brush section 31 is equipped with the water pressure regulating valve 32 and is detachably attached to the oscillating section 22. By pivoting the rotating brush section 31 via the pivoting section 22, cleaning can be performed regardless of the relative positions of the operator and the object surface. Furthermore, the water pressure adjustment valve 32 of the rotating brush section 31 is configured to spray cleaning water onto the object's surface, and by adjusting the water pressure adjustment valve 32, the water pressure during the spraying of cleaning water can be adjusted according to the degree of soiling on the object's surface.

[0022] With this configuration, if the dirt on the surface of an object is stubborn, the water pressure adjustment valve 32 can be adjusted to increase the water pressure when the cleaning water is sprayed. When the cleaning water hits the surface of the object, the force of the water pressure and the ultrafine pores further generated by the impact with the surface of the object allow the cleaning water itself to exhibit a high cleaning effect. Furthermore, if the dirt on the surface of an object is minor, or if it is undesirable to spray cleaning water at high water pressure depending on the condition of the surface of the object, the water pressure adjustment valve 32 can be adjusted to lower the water pressure when the cleaning water is sprayed. Thus, the water pressure adjustment valve 32 enables efficient cleaning work.

[0023] The water flow adjustment switch 41 is a switch that switches the strength of the water flow of the cleaning water flowing through the channel, and when used in combination with the water pressure adjustment valve 32, it is possible to finely adjust the force and water pressure of the cleaning water sprayed from the water pressure adjustment valve 32. In addition, a switch for adjusting the rotation speed of the brush of the rotating brush section 31 may be provided in addition to the water flow adjustment switch 41.

[0024] The ultrafine bubble generating device 51 is a device in which ultrafine bubbles are added as the washing water passes through the ultrafine bubble generating device 51, and its internal structure (not shown) may include, for example, a plurality of protrusions or small holes.

[0025] In this embodiment, the rotating brush section consists of two disc-shaped brushes 31a, but it goes without saying that one or more brushes may be appropriately selected and applied depending on the site conditions and the conditions of the object to be cleaned. Furthermore, as shown in Figures 3 and 4, for example, the rotating brush section 71, which is equipped with a cylindrical brush, can be replaced with the rotating brush section 31. The rotating brush section 71 is also equipped with the water pressure regulating valve 32. In Figures 3 and 4, the rotating brush section 71 is shown as having one cylindrical brush, but of course, depending on the site conditions and the conditions of the object to be cleaned, one or more brushes can be appropriately selected and applied.

[0026] Figure 5 is a schematic enlarged view of the tip portion of the bristles 81 that constitute the brush of the rotating brush section 31, 71. As shown in the figure, the bristles 81 may have multiple ultrafine bristles 82 that are thinner than the thickness of the bristles 81 formed at their tips. This configuration allows the bristles to reach even the smallest recesses on the surface of an object, resulting in a sufficient cleaning effect.

[0027] Furthermore, as shown in Figures 6 and 7, the bristles 81 constituting the brush of the rotating brush section 31, 71 may be arranged so that hard bristles 91 and soft bristles 92 are alternately arranged at predetermined intervals. By configuring it in this way, regardless of the degree of soiling on the object's surface, the rotating brush unit can provide sufficient cleaning power without having to replace the rotating brush unit.

[0028] Furthermore, a camera unit (not shown) capable of photographing the surface condition of the target object may be attached to the rotating brush units 31 and 71. By continuously checking the shape and cleaning status of the target object's surface via the camera unit, the work can be performed accurately and efficiently.

[0029] Figures 8 to 9 show a third embodiment of the object surface cleaning apparatus of the present invention, in which the object surface cleaning apparatus 11 can be used to clean the object surface by spraying ultrafine bubble water 12 onto it. At this time, the high cleaning ability of the ultrafine bubbles contained in the ultrafine bubble water 12 allows the surface of the object to be easily and thoroughly cleaned. Furthermore, the object surface cleaning device 11 is equipped with a rotating brush section 31 at the tip of its long rod section 21, and the cleaning by spraying the ultrafine bubble water 12 and the cleaning by brushing with the rotating brush section 31 work in synergy to achieve extremely high cleaning performance.

[0030] The ultrafine bubble water 12 is preferably obtained by incorporating ultrafine bubbles with extremely small diameters into pure water, which is water of high purity that contains little to no impurities, taking into consideration the physical load on the surface of the object to be sprayed and the environmental load due to it being basically an outdoor environment. The aforementioned pure water can be any water from which impurities have been sufficiently removed, such as distilled water or deionized water, and even tap water can 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 ultrafine bubbles of less than 1 μm (so-called ultra-ultrafine bubbles) can be used particularly favorably. Furthermore, by appropriately selecting and using the most effective diameter of the ultrafine bubbles according to the shape, structure, and material of the object to be cleaned, it is possible to consistently achieve high cleaning performance regardless of the properties of the object being cleaned.

[0031] As shown in Figures 8 to 9, the object surface cleaning device 11 of the present invention comprises a long rod section 21 with a built-in cleaning water flow path (not shown), a swivel section 22 provided at one end of the long rod section 21, a rotating brush section 31 detachably attached to the swivel section 22, a connecting section 23 provided at the other end of the long rod section 21, a water flow adjustment switch 41 attached at a predetermined position on the long rod section 21, an ultrafine bubble generating device 51 attached at a predetermined position on the long rod section 21, a chlorine removal device 111 attached at a predetermined position on the long rod section 21, and a water pressure adjustment valve 32 attached to the rotating brush section 31.

[0032] The object surface cleaning device 11 is connected via the connection part 23 to tap water, a river pump, a water storage tank, or other means of supplying cleaning water (not shown). 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, chlorine is removed via the chlorine removal device 111, and the cleaning water is then sprayed onto the object surface from the rotating brush part 31.

[0033] Thus, regardless of the means by which the cleaning water is supplied, in any environment, by connecting the means of supplying the cleaning water to the connection part 23 of the object surface cleaning device 11, for example via a hose, the cleaning water can be sprayed from the water pressure adjustment valve 32 of the rotating brush part 31. The cleaning by brushing of the rotating brush part 31, the cleaning by spraying the cleaning water, and the cleaning power of the ultrafine bubbles added to the cleaning water combine to achieve a very high cleaning capacity. In addition, by removing chlorine from the cleaning water via the chlorine removal device 111, even if some of the cleaning water remains on the object surface, it is possible to prevent the formation of stains such as limescale.

[0034] The long rod section 21 has a built-in flow path (not shown) for cleaning water, with a swivel section 22 at one end and a connection section 23 at the other end. A water flow adjustment switch 41 for the cleaning water flowing through the flow path, an ultrafine bubble generator 51 for adding ultrafine bubbles to the cleaning water, and a chlorine removal device 111 are attached to predetermined positions on the long rod section 21. Furthermore, the long rod portion 21 may be equipped with an extendable / retractable function (not shown) that allows it to extend or retract as appropriate.

[0035] The rotating brush section 31 is equipped with the water pressure regulating valve 32 and is detachably attached to the oscillating section 22. By pivoting the rotating brush section 31 via the pivoting section 22, cleaning can be performed regardless of the relative positions of the operator and the object surface. Furthermore, the water pressure adjustment valve 32 of the rotating brush section 31 is configured to spray cleaning water onto the object's surface, and by adjusting the water pressure adjustment valve 32, the water pressure during the spraying of cleaning water can be adjusted according to the degree of soiling on the object's surface.

[0036] With this configuration, if the dirt on the surface of an object is stubborn, the water pressure adjustment valve 32 can be adjusted to increase the water pressure when the cleaning water is sprayed. When the cleaning water hits the surface of the object, the force of the water pressure and the ultrafine pores further generated by the impact with the surface of the object allow the cleaning water itself to exhibit a high cleaning effect. Furthermore, if the dirt on the surface of an object is minor, or if it is undesirable to spray cleaning water at high water pressure depending on the condition of the surface of the object, the water pressure adjustment valve 32 can be adjusted to lower the water pressure when the cleaning water is sprayed. Thus, the water pressure adjustment valve 32 enables efficient cleaning work.

[0037] The water flow adjustment switch 41 is a switch that switches the strength of the water flow of the cleaning water flowing through the channel, and when used in combination with the water pressure adjustment valve 32, it is possible to finely adjust the force and water pressure of the cleaning water sprayed from the water pressure adjustment valve 32. In addition, a switch for adjusting the rotation speed of the brush of the rotating brush section 31 may be provided in addition to the water flow adjustment switch 41.

[0038] The ultrafine bubble generating device 51 is a device in which ultrafine bubbles are added as the washing water passes through the ultrafine bubble generating device 51, and its internal structure (not shown) may include, for example, a plurality of protrusions or small holes.

[0039] The chlorine removal device 111 is a device that removes chlorine from the washing water as the washing water passes through the device. Its internal structure (not shown) may include, for example, a device in which activated carbon is filled into the flow path of the washing water. Of course, the device is not limited to chlorine removal using activated carbon, and may also be a chlorine removal device using other methods.

[0040] In this embodiment, the rotating brush section consists of two disc-shaped brushes 31a, but it goes without saying that one or more brushes may be appropriately selected and applied depending on the site conditions and the conditions of the object to be cleaned. Furthermore, as shown in Figures 10 and 11, for example, the rotating brush section 71, which is equipped with a cylindrical brush, can be replaced with the rotating brush section 31. The rotating brush section 71 is also equipped with the water pressure regulating valve 32. In Figures 10 and 11, the rotating brush section 71 is shown as having one cylindrical brush, but of course, depending on the site conditions and the conditions of the object to be cleaned, one or more brushes can be appropriately selected and applied.

[0041] Figure 12 is a schematic enlarged view of the tip portion of the bristles 81 that constitute the brush of the rotating brush section 31, 71. As shown in the figure, the bristles 81 may have multiple ultrafine bristles 82 that are thinner than the thickness of the bristles 81 formed at their tips. This configuration allows the bristles to reach even the smallest recesses on the surface of an object, resulting in a sufficient cleaning effect.

[0042] Furthermore, as shown in Figures 13 and 14, the bristles 81 constituting the brush of the rotating brush section 31, 71 may be arranged so that hard bristles 91 and soft bristles 92 are alternately arranged at predetermined intervals. By configuring it in this way, regardless of the degree of soiling on the object's surface, the rotating brush unit can provide sufficient cleaning power without having to replace the rotating brush unit.

[0043] Furthermore, a camera unit (not shown) capable of photographing the surface condition of the target object may be attached to the rotating brush units 31 and 71. By continuously checking the shape and cleaning status of the target object's surface via the camera unit, the work can be performed accurately and efficiently.

[0044] Thus, in the object surface cleaning apparatus of the present invention, even when an operator performs the cleaning work, sufficient cleaning power can be achieved through the combined effects of cleaning by brushing with the rotating brush, cleaning by spraying cleaning water, the cleaning ability of the ultrafine bubbles added to the cleaning water via the ultrafine bubble generation device, and the cleaning ability of the ultrafine bubbles further generated by the collision of the cleaning water with the object surface. Furthermore, by using ultrafine bubble water consisting of pure water and ultrafine bubbles, there is no physical load on the object being cleaned, and if necessary, a chlorine removal device can be used to avoid using environmentally harmful cleaning agents such as surfactants and de-icing agents, making it environmentally friendly and not damaging to the natural environment. [Industrial applicability]

[0045] Needless to say, the object surface cleaning apparatus of the present invention can be applied to cleaning the surfaces of all kinds of objects. Furthermore, since it does not require the use of cleaning agents that place a heavy physical burden on the equipment or a heavy burden on the surrounding natural environment, it can be used with all kinds of equipment and does not harm the surrounding natural environment.
