Description

  The present invention relates to a wall surface cleaning device, and more particularly to a wall surface cleaning device suitable for cleaning an outer wall or an inner wall of a building or the like.

  Conventionally, when cleaning the outer wall of a building, for example, a cleaning device having the following configuration has been used. In other words, it is connected to the recovery tank for storing the recovered garbage together with water, a suction pump for bringing the inside of the recovery tank into a negative pressure state, an exhaust hose for sending an exhaust flow discharged from the pump, and the recovery tank And a recovery hose that sucks dust together with water. In this apparatus, as the exhaust flow of the suction pump is ejected from the front end of the exhaust hose, the cleaning liquid is discharged and sprayed from a cleaning liquid tank provided near the front end of the exhaust hose (see, for example, Patent Document 1).

  In addition, as another cleaning device, granular water containing tourmaline, monazite, zinc oxide and borax is filled in a water activation tank, and the activated water obtained by passing water through the water activation tank is used as the cleaning object. There is one that sprays on the surface, cleans the surface, and forms a coating (for example, see Patent Document 2).

JP-A-10-66669 JP 2004-50043 A

  However, the former cleaning apparatus has a complicated structure even though it does not have a configuration for forming a coating on the outer wall.

  In the latter cleaning apparatus, the active water is sprayed on the surface of the object to be cleaned, and cannot be used for cleaning the wall surface of the building, particularly the high part of the outer wall or the inner wall.

  Therefore, an object of the present invention is to provide a wall surface cleaning device that can form a coating on a wall surface even from tap water and can be reliably recovered despite its simple and inexpensive structure.

  As a means for solving the above-mentioned problems, the present invention provides a wall surface cleaning device, a treated water generating unit for generating treated water for forming a coating on the wall surface, and treated water generated by the treated water generating unit. A configuration comprising a pressurizing unit for pressurizing, a cleaning unit for spraying treated water pressurized by the pressurizing unit on the wall surface, and a recovery unit for recovering water after sprayed on the wall surface by the cleaning unit It is what.

  With this configuration, the treated water is generated in the treated water generating unit, the treated water obtained in the pressurizing unit is pressurized and supplied to the cleaning unit, and the treated water is sprayed on the wall surface in the cleaning unit to form a coating on the wall surface. Then, the water obtained after spraying on the wall surface by the recovery unit can be recovered.

  When the treated water generating unit and the pressurizing unit are integrated, it is preferable in that the entire configuration can be made compact.

  If the said pressurization part is comprised with the heating and pressurization part which has a heating function for heating process water, it is preferable at the point which can form a film on a wall surface more appropriately.

  The cleaning part is substantially box-shaped, and a pipe part is mounted in a cleaning casing having an open front surface so that a rotating shaft formed at the center part can be rotated. The pipe part has nozzles at both ends. The nozzle is preferably formed so as to be inclined in the same circumferential direction around the rotation axis.

  With this configuration, the treated water can be sprayed toward the wall surface without requiring a special drive mechanism in the cleaning unit. For this reason, it becomes possible to make a washing | cleaning part light and to produce cheaply. Further, the pressurizing capacity of the pressurizing unit is not so required. In addition, since the treated water is sprayed circularly from the nozzle onto the wall surface, the coating can be uniformly formed over a wide range simply by moving the cleaning unit along the wall surface.

  The recovery unit recovers the treated water sprayed from the nozzle to the wall surface by setting a negative pressure in the cleaning space formed by confronting the front opening of the cleaning casing to the wall surface. A brush portion is provided at the opening edge portion, and the brush portion is ejected from the nozzle while maintaining a predetermined interval between the wall surface and the opening edge portion when the front opening of the cleaning casing faces the wall surface. It is preferable to prevent the treated water from splashing around the cleaning casing and to allow ambient air to be taken in.

  With this configuration, when the front opening of the cleaning casing faces the wall surface, the brush portion is interposed between the opening edge portion and the wall surface, so that the wall surface is not damaged. And since the washing space becomes negative pressure by the recovery part, the surrounding air is sucked in through the brush part, and the treated water after spraying on the wall surface is surely prevented while preventing the treated water from splashing around. Can be recovered.

  It is preferable to further include a filter unit that removes the contained solid matter from the treated water collected in the collecting unit in that not only the coating on the wall surface but also the wall surface can be washed.

  It is preferable that the water recovered in the recovery unit is returned to the treated water generation unit in that the amount of water to be discarded can be eliminated and resources can be used effectively.

  According to the present invention, since the treated water generating section is provided, it is possible to easily form a coating on the wall surface simply by supplying tap water. And since the water after forming a film can be reliably collect | recovered in a collection | recovery part, it does not scatter around. Therefore, it is possible to reliably form a coating not only on the outer wall of the building but also on the inner wall or the like where water is scattered.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a wall surface cleaning apparatus according to this embodiment. The wall cleaning apparatus is generally composed of a treated water generating unit 1, a heating / pressurizing unit 2, a cleaning unit 3, a filter unit 4, and a recovery unit 5.

  The treated water generation unit 1 is for making tap water into treated water suitable for cleaning wall surfaces, and a water activation tank 6 is filled with ceramics 7 containing tourmaline, mozzanite, zinc oxide and borax. (For details, see JP 2004-50043 A, etc.). Thereby, a trace amount of contents are eluted from the ceramics 7 into the tap water injected into the water activation tank 6 to promote water activation and obtain treated water. The treated water is sprayed onto the wall surface, thereby forming a film on the surface and having excellent gloss.

  The heating / pressurizing unit 2 has a configuration in which a storage tank 10 including a heater 9 and a pressurizing pump 11 are incorporated in a pressurizing casing 8. In the heating / pressurizing unit 2, the processing pump heated by the heater 9 in the storage tank 10 is supplied to the cleaning unit 3 in a pressurized state by driving the pressurizing pump 11. The heating temperature by the heater 9 and the pressurizing pressure by the pressurizing pump 11 are preferably adjustable.

  What is necessary is just to comprise so that an operator may determine heating temperature by selecting means, such as a switch, based on the material of the wall surface used as object. For example, if the wall surface is made of resin or wood, increasing the heating temperature may damage the wall surface. However, by setting the heating temperature appropriately, the temperature should be the most suitable for cleaning and film formation. Can do.

  Moreover, what is necessary is just to comprise a pressurization pressure so that an operator may determine with selection means, such as a switch, according to the use environment of the washing | cleaning part 3 mentioned later. For example, the higher the position of the cleaning unit 3 relative to the position of the storage tank 10 is, the higher the pressure applied by the pressure pump 11 is adjusted, so that the treated water can always be sprayed onto the wall surface with the same ejection pressure. .

  Various selection means such as a dial type and a digital type can be used. If the heating temperature, the temperature and material, the pressure from the heating / pressurizing unit 2 to the cleaning position, etc. The selection can be made from various selection items. About the heating temperature and the pressurizing pressure, the conditions that are normally used may be set as default values. Further, the selection means can be provided not only in the heating / pressurizing unit 2 but also in the cleaning unit 3 so that the selection unit can be adjusted while performing a cleaning operation. Furthermore, the pressurizing pressure may be automatically adjusted by detecting the drive current of the pressurizing pump 11 for the change in the load acting on the pressurizing pump 11.

  As shown in FIG. 2, the washing | cleaning part 3 is a substantially box-shaped shape, and is the structure which attached the pipe part 13 rotatably in the washing | cleaning casing 12 which a front surface opens.

  As shown in FIG. 3, an inflow portion 15 to which a hose H <b> 1 extending from the heating / pressurizing portion 2 is connected via a trigger portion 14 is formed on the rear wall of the cleaning casing 12. The trigger part 14 includes a gripping part 16 to which the hose H1 is directly connected. A flow path is formed in the gripping part 16, and the treated water supplied from the hose H1 is guided to the pipe part 13. An opening / closing valve (not shown) is provided in the middle of the flow path, and is normally closed. The trigger part 14 is provided with a trigger 17 on the inner side which has a rectangular shape. When the trigger 17 is pulled with a hand holding the gripping part 16, the on-off valve is interlocked so that the flow path in the gripping part 16 is closed. Switch to open state.

  Further, an outflow portion 18 to which a hose H2 for collecting the treated water in the cleaning casing 12 and flowing it down to the collecting portion 5 is formed on the side wall of the cleaning casing 12 (a wall positioned below when used). Has been.

  Furthermore, as shown in FIGS. 2 and 3, the opening edge of the cleaning casing 12 is provided with a brush portion 19 provided with a plurality of bristles made of heat-resistant nylon, for example. The brush portion 19 functions as a so-called cushion when the opening edge side of the cleaning casing 12 is pressed against the wall surface (outer wall or inner wall) of the building, and prevents the wall surface from being damaged. Moreover, the brush part 19 is provided densely and prevents the treated water in the cleaning space formed by the cleaning casing 12 and the wall surface from splashing around. Furthermore, ambient air can be sucked into the cleaning space. In this case, by maintaining an appropriate negative pressure state with the brush portion 19, the cleaning portion 3 may be attracted to the wall surface, and the force for the operator to hold the cleaning portion 3 may be reduced. Since the brush part 19 is easily elastically deformed, the cleaning part 3 can be smoothly moved along the wall surface.

  In the pipe portion 13, a rotating shaft 20 provided at the central portion is rotatably supported by a central portion of the rear wall of the cleaning casing 12 (a portion continuing to the inflow portion 15). For the support structure, for example, a waterproof ball bearing or the like can be used. The rotating shaft 20 is hollow, and treated water is supplied from the heating / pressurizing unit 2 through the circulation unit 21 formed in the cleaning casing 12 and flows to both ends of the pipe unit 13. Nozzles 22 are respectively formed at both ends of the pipe portion 13.

  The nozzles 22 are formed so that the blowing direction is inclined in the same circumferential direction around the rotation shaft 20. Thereby, if treated water is ejected from the nozzle 22, the pipe portion 13 is configured to rotate around the rotation shaft 20 by the reaction force. In addition, since the nozzles 22 are formed only in two places, even if an inexpensive one having a discharge capacity that is not so high is used for the pressurizing pump 11, the discharge pressure of the treated water is not reduced. In addition, the ejection pressure of the treated water from the nozzle 22 is suppressed compared with the case of washing | cleaning so that a more suitable film can be formed with a wall surface with treated water.

  The filter unit 4 removes contained solids such as soil and pebbles from the washing water collected from the washing unit 3. However, the filter part 4 is not necessarily required as long as the treated water is sprayed on the cleaned wall surface to form a coating on the surface.

  The recovery unit 5 accommodates a recovery pump 24 in the recovery casing 23 and is connected to the outflow part 18 of the cleaning casing 12 via a hose H4. Then, by driving the recovery pump 24, the cleaning space of the cleaning unit 3 is set to a negative pressure, and the treated water sprayed on the wall surface is recovered.

  Next, the operation of the wall surface cleaning apparatus having the above configuration will be described.

  The tap water is led from the tap to the water activation tank 6 of the treated water generating unit 1 through the hose H3, and the components contained in the ceramic 7 are eluted in the tap water to obtain the treated water. The heater 9 is energized by the heating / pressurizing unit 2 and the pressure pump 11 is driven. As a result, the treated water obtained in the water activation tank 6 flows into the storage tank 10 in the pressurized casing 8 and is heated by the heater 9 to become high-temperature treated water. Pressurized and ready to be supplied from the cleaning unit 3.

  In this state, the grip portion 16 is gripped and the brush portion 19 provided at the opening edge of the cleaning casing 12 is pressed against the wall surface to be cleaned. The presence of the brush portion 19 can prevent the wall surface from being damaged. When the trigger 17 is pulled, the high-temperature treated water from the heating / pressurizing unit 2 is supplied to the pipe unit 13 in a pressurized state. Thereby, treated water is sprayed toward the wall surface from the nozzles 22 respectively formed at both ends of the pipe portion 13. Since the ejection direction from the nozzle 22 is as described above, the pipe portion 13 is rotated by the reaction force caused by the ejection. Therefore, the treated water ejected from the nozzle 22 is sprayed on the same circumference with respect to the wall surface. Therefore, when the cleaning unit 3 is moved while sliding the brush along the wall surface, the treated water can be uniformly sprayed on the wall surface within a predetermined range (a range in which the water moves while being covered with the cleaning casing 12). . At this time, a film is formed on the wall surface.

  Further, the recovery pump 24 is driven by the recovery unit 5, and the cleaning space formed by the cleaning casing 12 and the pressed wall surface is set to a negative pressure. Thereby, after the treated water is sprayed on the wall surface, it is recovered to the recovery part 5 via the filter part 4. In addition, ambient air is sucked into the cleaning space through the brush portion 19. In addition, the brush portion 19 is closely arranged with bristles. Therefore, treated water does not scatter around.

  The water collected in the collection unit 5 is drained into sewage or the like after the solids such as soil are removed by the filter unit 4. This water is water having substantially the same components as the original tap water obtained after the treated water obtained in the water activation tank 6 is adhered to the wall surface. Moreover, the soil and the like are removed by the filter unit 4. Therefore, the natural environment is not destroyed even if it flows down into sewage or the like as it is.

  In addition, in the said embodiment, although the treated-water production | generation part 1 and the heating / pressurization part 2 were provided separately, it is also possible to set it as the integral structure which has both functions. That is, the treated water generation unit 1 may be separately provided with a heater 9 and a pump 11 so that the obtained treated water is immediately heated and pressurized. Thereby, an extra apparatus becomes unnecessary and it becomes possible to simplify the structure of a wall surface washing apparatus. Furthermore, if the collection part 5 is also integrated (accommodated in one casing), the configuration can be further simplified.

  Moreover, although the said embodiment demonstrated the case where the filter part 4 was provided and a film was formed in the wall surface by treated water, it was made to wash | clean by enlarging the water pressure sprayed on a wall surface from the nozzle 22 before formation of a film. do it. In this case, what is necessary is just to replace | exchange to the washing | cleaning part 3 provided with the nozzle 22 of a different internal diameter by washing | cleaning and film formation. And in the case of washing | cleaning, the treated water production | generation part 1 becomes unnecessary and what is necessary is just to let tap water flow in into the storage tank 10 of a heating and pressurization part directly.

  In the above embodiment, the treated water is sprayed onto the wall surface and then collected, and then discarded. However, the treated water (tap water in the case of cleaning) may be circulated to be reusable. That is, the water discarded from the collection unit 5 may be returned to the water activation tank 6 to compensate for the shortage with tap water. Thereby, it becomes possible to greatly suppress the amount of water to be used.

  In this case, if the capacity of the water activation tank 6 is set to a value sufficient for cleaning or forming a coating for the target wall surface, the hose H3 for guiding tap water and the hose H5 for discarding are unnecessary. Become. And if the treated water production | generation part 1, the heating / pressurization part 2, and the collection | recovery part 5 are provided in a casing and it is set as integral structure, hose H3 other than the two hoses H1 and H2 which connect a casing and the washing | cleaning part 3 will be demonstrated. ˜H5 is not necessary, and a very simplified configuration can be obtained. In addition, if a caster or the like is provided on the lower surface of the casing, it becomes easy to carry and the degree of freedom of the carrying place is expanded, so that it is very easy to use. Further, if the two hoses have a double structure and a flow path for guiding the treated water to the cleaning unit 3 is formed on the inner side, the treated water after sprayed on the wall surface on the outer side is refluxed. It becomes possible to make the structure cleaner.
