Embodiments for Carrying Out the Invention

[0018] Referring to the drawings, a cleaning device according to an embodiment of the present invention will be described in detail.

[0019] FIG. 1 is a diagram schematically showing the configuration of a cleaning device 1 according to an embodiment of the present invention. An operator can clean a cleaning target surface SC with high work efficiency using the cleaning device 1. The cleaning target surface SC is, for example, a flat surface, such as a window, a tile, a wall, a floor, or the like.

[0020] As shown in FIG. 1, the cleaning device 1 includes a housing 10 that supports each part. The housing 10 is made of, for example, resin. The housing 10 supports a tank 12, a pump 14, an injection nozzle 16, a rotary brush 18, a brush drive unit 20, a wiper 22, a suction nozzle 24, a sewage recovery path 26, a filter 28, a suction drive unit 30, and a battery 32.

[0021] FIG. 2 is a diagram showing the configuration of the cleaning device 1 in detail. FIGS. 3A and 3B and FIGS. 4A and 4B are diagrams showing the configuration of the pump 14. FIG. 5 is a view of the internal structure of the cleaning device 1 as seen from above, mainly showing the configuration of the sewage recovery path 26.

[0022] The operator uses the cleaning device 1 in the posture shown in FIG. 1, for example. Specifically, the operator holds the cleaning device 1 in a posture where the wiper 22 is located above the rotary brush 18, presses the rotary brush 18 containing the cleaning liquid CL against the cleaning target surface SC, and while pressing the wiper 22 against the cleaning target surface SC, pulls the cleaning device 1 downward along the cleaning target surface SC (see arrow A in FIG. 1).

[0023] The housing 10 supports the rotary brush 18 and the wiper 22 in a positional relationship such that when the rotary brush 18 presses against the cleaning target surface SC, the wiper 22 also presses against the cleaning target surface SC. Therefore, the operator can press both the rotary brush 18 and the wiper 22 against the cleaning target surface SC at once.

[0024] As the operator presses the rotating brush 18 and wiper 22 against the surface SC to be cleaned and pulls the cleaning device 1 downward along the surface SC, the rotating brush 18 applies the cleaning solution CL to the surface SC, causing the loosened dirt to be scrubbed away by the rotating brush 18, while any remaining deposits on the surface SC (specifically, dirty water SW mixed with the cleaning solution CL) are wiped away by the wiper 22.

[0025] In the cleaning device 1, dirt removal by the rotating brush 18 and wastewater wiping by the wiper 22 are performed simultaneously. Therefore, the operator can clean the surface SC with high work efficiency.

[0026] Furthermore, the cleaning device 1 can be used to clean the target surface SC by simply pulling it downward along the surface SC. Therefore, for example, the cleaning device 1 may be attached to a robot arm to perform the cleaning work. In this case, the robot arm automatically moves the cleaning device 1 up and down along the target surface SC. This reduces the burden on the operator.

[0027] The operator can perform cleaning work while gripping the cleaning device 1 with the gripping portion 10A formed on the housing 10. A battery 32 is detachably housed inside the gripping portion 10A. The operator can charge the battery 32 removed from the gripping portion 10A with a charger (not shown), and can also install the charged battery 32 back into the gripping portion 10A.

[0028] The battery 32 is the power source for the brush drive unit 20 and the suction drive unit 30. When the hand switch 10B, located on the gripping unit 10A, is turned on, power is supplied to the brush drive unit 20 and the suction drive unit 30. When the hand switch 10B is turned off, the power supply to the brush drive unit 20 and the suction drive unit 30 is cut off.

[0029] Tank 12 is an example of a storage unit for containing the cleaning solution CL. The cleaning solution CL is, for example, a cleaning solution for the surface to be cleaned (e.g., for windows), water, or a mixture of detergent and water.

[0030] The tank 12 is detachable from the housing 10. The operator can clean the tank 12 after removing it from the housing 10 and also replenish the tank 12 with cleaning solution CL.

[0031] Pump 14 is an example of a pumping unit that pumps the cleaning liquid CL from the tank 12. In this embodiment, pump 14 is a hand pump that sucks up and pushes out the cleaning liquid CL from the tank 12 by manual operation by an operator. In another embodiment, pump 14 may be an electric pump that sucks up and pushes out the cleaning liquid CL from the tank 12 using an electric motor.

[0032] The pump 14 includes a lever 14A, a spring 14B, a plunger 14C, a staging 14D, and a cover 14E. One end of the lever 14A is connected to the spring 14B, and the other end is connected to the plunger 14C. One end of the spring 14B is connected to the lever 14A, and the other end is connected to the gripping part 10A.

[0033] Figures 3A and 3B show the state of the pump 14 when the lever 14A is not pulled (in other words, when the spring 14B is at its natural length). Figures 4A and 4B show the state of the pump 14 when the lever 14A is pulled by an operator. Figures 3A and 4A are side views of the inside of the staging 14D. Figures 3B and 4B are top views of the inside of the staging 14D. In Figures 3B and 4B, the lever 14A and spring 14B, which are components of the pump 14, are not shown.

[0034] Water inlets 14Da and drain outlets 14Db are formed on the bottom and top surfaces of the staging 14D, respectively. The cover 14E is fixed integrally with the plunger 14C. An opening 14Ea is formed in the cover 14E.

[0035] The cleaning fluid CL in the tank 12 is filled into the staging area 14D via the water inlet 14Da. ​​The cleaning fluid CL filled into the staging area 14D is discharged to the spray nozzle 16 via the drain port 14Db and the opening 14Ea.

[0036] When the operator pulls lever 14A, the plunger 14C connected to lever 14A slides inside the staging 14D in the direction of arrow B (see Figures 4A and 4B) and closes the water inlet 14Da. ​​At the same time, the opening 14Ea of the cover 14E, which moves integrally with the plunger 14C, communicates with the drain port 14Db of the staging 14D. The communication between the drain port 14Db and the opening 14Ea connects the staging 14D and the hose 34.

[0037] One end of the hose 34 is connected to the staging 14D via the drain port 14Db and opening 14Ea, and the other end is connected to the spray nozzle 16.

[0038] When the operator releases their finger from lever 14A, the plunger 14C slides inside the staging 14D in the direction of arrow C (see Figures 3A and 3B) in conjunction with the spring 14B returning to its natural length, and retracts from the water inlet 14Da. ​​At the same time, the cover 14E, which moved integrally with the plunger 14C, closes the drain port 14Db. As the plunger 14C retracts from the water inlet 14Da, the staging 14D and the hose 36 are connected.

[0039] One end of the hose 36 is connected to the staging 14D via the water inlet 14Da, and the other end is placed inside the tank 12.

[0040] When the operator releases their finger from lever 14A, the plunger 14C slides in the direction of arrow C, causing the air pressure inside the staging area 14D to decrease. This draws up the cleaning fluid CL from tank 12 and fills the staging area 14D through hose 36 and water inlet 14Da (see arrow D in Figure 3A).

[0041] When the operator pulls lever 14A, the plunger 14C slides in the direction of arrow B, and the cleaning fluid CL in the staging 14D is pumped to the spray nozzle 16 via the drain port 14Db, opening 14Ea, and hose 34 (see arrow E in Figure 4A).

[0042] The spray nozzle 16 is an example of a discharge unit that sprays (discharges) the cleaning fluid CL, which is pumped by the pump 14, toward the rotating brush 18. Multiple spray nozzles 16 are arranged at predetermined intervals in the direction of the rotation axis AX of the rotating brush 18 (the direction perpendicular to the plane of the paper in Figure 2, and also parallel to the surface SC to be cleaned).

[0043] Thus, the tank 12, pump 14, and spray nozzle 16 function as a supply unit that supplies cleaning fluid CL to the rotating brush 18.

[0044] The rotating brush 18 is an example of a cleaning fluid applicator that applies cleaning fluid CL to the surface SC to be cleaned, and is rotatably supported by the housing 10. The rotating brush 18 includes a brush member 18A that is pressed against the surface SC to be cleaned. The brush member 18A carries the cleaning fluid CL sprayed from the spray nozzle 16.

[0045] The cleaning fluid CL is sprayed onto the brush member 18A from each of the multiple spray nozzles 16 arranged in the direction of the rotation axis AX. As a result, the rotating brush 18 becomes wet with the cleaning fluid CL evenly distributed along its entire length.

[0046] When the brush member 18A is pressed against the surface SC to be cleaned, it applies the supported cleaning solution CL to the surface SC. The brush member 18A is made of bristles made of, for example, plant, animal, metallic, or synthetic fibers.

[0047] The rotating brush 18 is removably supported by the housing 10. Here, the required function of the rotating brush 18 changes depending on the material of the surface SC to be cleaned (e.g., window, tile, wall, floor material, etc.). The operator can replace the rotating brush 18 with one that has the optimal cleaning member, taking into account the material of the surface SC to be cleaned. Examples of cleaning members other than the brush member 18A include cloth members and sponge-like elastic members.

[0048] The brush drive unit 20 includes a rotary motor 20A and a transmission member 20B. The transmission member 20B is, for example, a chain that transmits the driving force of the rotary motor 20A to the shaft 18B of the rotary brush 18.

[0049] When the hand switch 10B is turned on, the rotary motor 20A rotates, and its driving force is transmitted to the shaft 18B via the transmission member 20B. As a result, the rotary brush 18 rotates around the rotation axis AX (with the shaft 18B as the axis of rotation).

[0050] When the rotating brush 18 is pressed against the surface to be cleaned SC and a driving force is transmitted to it, it rotates on the surface to be cleaned SC in a rubbing motion. In other words, the brush drive unit 20 is an example of a rotational drive unit that causes the rotating brush 18, which is pressed against the surface to be cleaned SC, to rotate on the surface to be cleaned SC.

[0051] By applying the cleaning solution CL, the loosened dirt is scrubbed away by the rotating brush 18. Therefore, not only relatively easy-to-remove dust and dirt such as sand and pollen, but also solid substances such as bird droppings and long-standing oil stains can be removed from the surface SC being cleaned.

[0052] The wiper 22 wipes away the wastewater SW, which is a deposit remaining on the surface SC to be cleaned to which the cleaning solution CL has been applied, from the surface SC to be cleaned.

[0053] More specifically, the wiper 22 includes a pair of wiper rubbers 22A and 22B. The upper wiper rubber 22A is more flexible (has a lower modulus of elasticity) than the lower wiper rubber 22B, and is more easily conforms to the cleaning surface SC when pressed against it. The wiper rubber 22A, which has high adhesion to the cleaning surface SC, wipes away the dirty water SW, while the less flexible and relatively hard wiper rubber 22B receives the dirty water SW wiped away by the wiper rubber 22A and guides it to the suction nozzle 24.

[0054] The wiper 22 is removably supported by the housing 10. Therefore, the operator can replace a deteriorated wiper 22 with a new one.

[0055] Furthermore, the operator can replace the wiper 22 with one of a different size depending on the area of ​​wastewater SW they want to wipe. In this embodiment, as shown in Figure 5, the wiper 22 has a length approximately equal to the width of the housing 10. By replacing the wiper 22 with one that is longer than the width of the housing 10, the operator can wipe a wider area of ​​wastewater SW at once.

[0056] The suction nozzle 24 is formed at the tip of the housing 10 and sucks up the wastewater SW wiped away by the wiper 22. Thus, the suction nozzle 24 is an example of an intake port that draws in the wastewater SW wiped away by the wiper 22.

[0057] As shown in Figure 5, the suction nozzle 24 has a width approximately the same as that of the housing 10. The wiper rubber 22A is attached to the upper side of the suction nozzle 24, and the wiper rubber 22B is attached to the lower side of the suction nozzle 24. Therefore, most of the wastewater SW that is wiped by the wiper rubber 22A and received by the wiper rubber 22B is sucked into the suction nozzle 24.

[0058] The wastewater recovery channel 26 is an example of a fluid channel connecting the suction nozzle 24 and the tank 12. In Figures 2 and 5, the wastewater recovery channel 26 is hatched for convenience. As shown in Figure 2, the wastewater recovery channel 26 is formed inside the housing 10 so as to follow the top surface and sides of the housing 10. Also, as shown in Figure 5, the wastewater recovery channel 26 is formed so as to gradually narrow in width.

[0059] A filter 28 is installed in the middle of the narrowed wastewater collection channel 26. The filter 28 removes waste contained in the wastewater SW. That is, the wastewater SW sucked into the suction nozzle 24 flows through the wastewater collection channel 26 and is filtered by the filter 28. The cleaning solution CL separated from the wastewater SW by filtration by the filter 28 is collected in the tank 12.

[0060] The filter 28 is detachable from the housing 10. The operator can clean and reattach the filter 28 after removing it from the housing 10, or replace it with a new filter 28.

[0061] The suction drive unit 30 includes a suction motor 30A and a suction fan 30B. When the hand switch 10B is turned on, the suction motor 30A is driven, and the suction fan 30B, which is supported by the shaft 30Aa of the suction motor 30A, rotates. This generates an airflow that draws air from the suction nozzle 24 into the tank 12. As a result, the wastewater SW wiped off by the wiper 22 is sucked from the suction nozzle 24 into the wastewater recovery path 26, filtered by the filter 28 to become cleaning liquid CL, and collected in the tank 12.

[0062] In this manner, the suction drive unit 30 sucks the wastewater SW, which has been wiped away by the wiper 22, from the suction nozzle 24 towards the tank 12.

[0063] Furthermore, the suction nozzle 24, wastewater recovery path 26, filter 28, and suction drive unit 30 form a recovery unit that recovers the cleaning solution CL contained in the wastewater SW remaining on the surface SC to be cleaned into the tank 12. In the cleaning device 1, the cleaning solution CL used to clean the surface SC can be recovered by the recovery unit and reused. Therefore, the amount of cleaning solution CL used can be kept to a minimum.

[0064] For example, if the cleaning solution CL runs out while cleaning windows on the upper floors of a building, the gondola carrying the worker must be lowered to the ground to replenish the cleaning solution CL. In the cleaning device 1 according to this embodiment, a small amount of cleaning solution CL is required for cleaning, so the cleaning solution CL is less likely to run out. Therefore, for example, the cleaning of building windows can be completed without lowering the gondola to the ground to replenish the cleaning solution CL.

[0065] Furthermore, in cleaning device 1, the amount of wastewater SW discharged outside cleaning device 1 is reduced by recovering and reusing the cleaning solution CL. Therefore, the workload for wastewater disposal is reduced.

[0066] The housing 10 includes a wall portion 10E that covers the top and rear of the rotating brush 18. Here, "rear of the rotating brush 18" refers to the position that faces the surface to be cleaned SC when the rotating brush 18 is pressed against the surface to be cleaned SC, with the rotating brush 18 in between.

[0067] The wall section 10E receives the cleaning liquid CL that is splashed from the rotating brush 18. This prevents the cleaning liquid CL from splashing into the surrounding area.

[0068] Thus, the wall portion 10E is an example of a guard portion that receives the cleaning liquid CL scattered from the rotating brush 18.

[0069] U-shaped grooves 10F are formed on the surface of the wall portion 10E. In Figure 2, hatching is applied to the U-shaped grooves 10F for convenience. The U-shaped grooves 10F are formed extending from the upper end to the lower end of the wall portion 10E. Multiple U-shaped grooves 10F are formed, for example, at predetermined intervals in the direction of the rotation axis AX.

[0070] The cleaning liquid CL that is scattered from the rotating brush 18 and adheres to the U-shaped channel 10F flows downward within the U-shaped channel 10F. A receiving port 10G is provided at the lower end of the U-shaped channel 10F to receive the cleaning liquid CL that has flowed down within the U-shaped channel 10F.

[0071] The receiving port 10G is connected to the tank 12. Therefore, the cleaning solution CL received at the receiving port 10G is dripped into the tank 12.

[0072] Thus, the U-shaped channel 10F is a groove formed in the wall portion 10E, and is an example of a groove that guides the cleaning liquid CL that has been scattered and adhered from the rotating brush 18 into the tank 12, and also serves as a recovery section that collects the cleaning liquid CL into the tank 12.

[0073] A hand switch 10C is provided on the gripping part 10A. Each time the operator presses the hand switch 10C, the rotation direction of the rotating brush 18 switches between clockwise and counterclockwise.

[0074] When the rotating brush 18 is rotated clockwise, the direction of movement of the rotating brush 18 relative to the surface SC to be cleaned (direction of arrow A in Figure 1) and the direction of rotation become aligned, increasing the force with which the rotating brush 18 rubs against the surface SC. As a result, the cleaning ability is improved.

[0075] When the rotating brush 18 is rotated counterclockwise, the wastewater SW adhering to the surface SC to be cleaned tends to splash upwards from the rotating brush 18 (in other words, towards the suction nozzle 24). As a result, the recovery rate of the cleaning solution CL is improved.

[0076] The gripping section 10A is provided with an operating knob 10D. The rotation speed of the rotating brush 18 changes according to the amount of operation performed on the operating knob 10D by the operator. When the rotation speed of the rotating brush 18 increases, for example, the cleaning ability improves. When the rotation speed of the rotating brush 18 decreases, for example, the power consumption of the rotating motor 20A decreases.

[0077] The above is a description of exemplary embodiments of the present invention. Embodiments of the present invention are not limited to those described above, and various modifications are possible within the scope of the technical idea of ​​the present invention. For example, embodiments of the present invention also include combinations of embodiments explicitly shown in the specification or obvious embodiments as appropriate. [Explanation of Symbols]
