Summary of the Invention

Problems to be Solved by the Invention

[0005] In the boot washing device disclosed in Patent Document 1, since sludge and the like clog the dust trap, the cleaning liquid accumulates, so it is necessary to remove the sludge accumulated in the dust trap. As a result, there is a problem that the cleaning liquid containing sludge cannot be efficiently discharged.

[0006] The present invention has been made to solve the above problems, and one object of the present invention is to provide a boot washing device capable of efficiently discharging the cleaning liquid containing sludge.

Means for Solving the Problems

[0007] To achieve the above objective, a boot cleaning device in one aspect of this invention comprises a housing with an opening for introducing boots to be cleaned, a brush disposed inside the housing and driven by a motor to clean the boots, a cleaning liquid supply unit that supplies cleaning liquid to the inside of the housing during cleaning, and an outlet provided at the bottom of the housing for discharging the cleaning liquid used to clean the boots, wherein the lower part of the inside of the housing has a tapered inclined surface that narrows towards the outlet and slopes downward, and the motor is located on the opposite side from the outlet. And, on the opposite side of the tapered inclined surface It is further equipped with a cover member that is mounted inside the casing and covers the motor.

[0008] In a boot cleaning device according to one aspect of this invention, as described above, the lower part of the inside of the housing has a tapered inclined surface that narrows towards the discharge port and slopes downward. This allows the cleaning liquid containing sludge to be collected and discharged from the discharge port without the need for a dust trap. As a result, there is no need to remove the sludge accumulated in the dust trap, and the cleaning liquid containing sludge can be discharged efficiently.

[0009] In the boot washing device according to the first aspect described above, preferably, the housing is configured to widen towards the discharge port and sandwich the tapered inclined surface from both sides, and has a pair of wide inclined surfaces that slope downward toward the tapered inclined surface. With this configuration, even when the washing liquid is supplied to a wide area inside the housing, the washing liquid containing sludge can be effectively collected toward the tapered inclined surface via the wide inclined surfaces, so that the washing liquid containing sludge can be discharged more efficiently.

[0010] In the boot washing device according to the first aspect described above, preferably, the motor is located at the bottom of the housing opposite the discharge port and is attached to the bottom of the housing opposite the tapered inclined surface. ru. This configuration allows the motor to be placed inside the housing, making the boot cleaning device more compact compared to when the motor is located outside the housing. Furthermore, the presence of a cover prevents cleaning fluid from adhering to the motor located inside the housing.

[0011] In this case, preferably, the cover member has an inclined upper surface portion that slopes downward toward the tapered inclined surface, and a step portion is provided between the inclined upper surface portion of the cover member and the tapered inclined surface. With this configuration, the cleaning liquid containing sludge can flow from the cover member to the tapered inclined surface by the inclined upper surface portion and the step portion, thereby preventing the cleaning liquid containing sludge from accumulating on the upper surface of the cover member.

[0012] In the boot cleaning device according to the first aspect described above, preferably, the brush is mounted in the upper part of the inside of the housing and includes a rotating shaft having an end that protrudes outward from the housing, and the housing is provided with a water receiving section configured to receive water that flows downward along the outer surface of the housing via the rotating shaft and to return the water to the inside of the housing, and the water receiving section is provided at a position corresponding to the end of the rotating shaft and below the end. With this configuration, the water receiving section can return water (cleaning solution) that has leaked to the outside of the housing back to the inside of the housing and discharge it from the outlet, thereby suppressing water leakage to the outside (outer surface) of the housing. Furthermore, by suppressing water leakage to the outside (outer surface) of the housing, the user is saved the trouble of removing water that has adhered to the outside of the housing.

[0013] In this case, preferably, the water receiving portion is provided at a position corresponding to the end of the rotating shaft and below the end, and is a cut-out hole that protrudes outward from the housing. With this configuration, the water receiving portion can be integrally formed with the housing, eliminating the need to provide it as a separate component, thereby reducing the number of parts and the assembly time.

[0014] In the boot cleaning device according to the first aspect described above, preferably, the amount of protrusion of the cut-out hole from the outer surface of the housing is less than or equal to the amount of protrusion of the end of the rotating shaft from the outer surface of the housing. With this configuration, the cut-out hole can be made relatively small, thereby suppressing an increase in the distance between the two outer surfaces (between the two outer ends) in the axial direction of the rotating shaft of the housing. As a result, even if a cut-out hole is provided, an increase in size can be suppressed. In addition, because the cut-out hole can be made relatively small, it is possible to suppress the spraying of cleaning liquid from the inside of the housing to the outside through the cut-out hole.

[0015] In the boot washing device according to the first aspect described above, preferably, the horizontal length of the water receiving portion along the outer surface of the housing is greater than or equal to the diameter of the rotating shaft. With this configuration, the horizontal end of the water receiving portion is located outside the outer circumference of the rotating shaft, so that water leaking to the outside along the outer circumference of the rotating shaft can be reliably received by the water receiving portion, and the water that leaks to the outside can be returned to the inside of the housing.

[0016] In the boot cleaning device according to the first aspect described above, preferably, the brush is mounted in the upper part of the interior of the housing and includes a rotating shaft having an end that protrudes outward from the housing, and comprises a bearing portion mounted on the outer surface of the housing to support the rotating shaft and protruding outward from the housing, and a protective cap attached to the bearing portion and configured to cover the end of the rotating shaft. With this configuration, since the end of the rotating shaft is covered by the protective cap, it is possible to suppress water from leaking out to the outside along the rotating shaft.

[0017] In the boot washing device according to the above first aspect, preferably, the housing is composed of a thin stainless steel plate joined by rivets, and a water stop material is filled in the joining portion. With this configuration, the joining strength can be increased by rivet joining. In addition, by forming it from a thin stainless steel plate, while increasing the strength of the boot washing device, the boot washing device can be made lighter, and a plurality of boot washing devices can be stacked and stored. Further, since the water stop material is filled, it is possible to suppress the leakage of the cleaning liquid to the outside from the joining portion.

Effect of the Invention

[0018] According to the present invention, as described above, it is possible to provide a boot washing device capable of efficiently discharging the cleaning liquid containing sludge.

Mode for Carrying Out the Invention

[0020] Hereinafter, the first embodiment will be described based on the drawings.

[0021] [First Embodiment] (Configuration of the boot washing device) The boot cleaning device 100 of the first embodiment will be described with reference to Figures 1 to 8. As shown in Figure 1, the boot cleaning device 100 comprises a housing 1, a brush 2, a cleaning liquid supply unit 3, and a discharge port 4. In the first embodiment, the vertical direction is the Z direction, the horizontal direction is the X direction, and the depth direction is the Y direction.

[0022] A user wearing boots 50 stands on the Y1 side of the boot cleaning device 100, and the boots 50, as worn by the user, are inserted into the boot cleaning device 100 through the opening 1a. Then, the sludge attached to the boots 50 is removed and the boots are cleaned. In this specification, "sludge" is used as a general term for mud and dirt attached to the boots 50.

[0023] The housing 1 has a rectangular or cubic shape. The housing 1 is made of thin stainless steel sheets joined together by rivets. A waterproofing material is filled into the joints of the stainless steel sheets. The waterproofing material is, for example, silicone sealant or adhesive. The housing 1 is fitted with a handle 11 for carrying the boot washing device 100 and wheels 12. The handle 11 is configured to be rotatable. The handle 11 can be fixed in a position rotated to a predetermined angle. Furthermore, by rotating the handle 11 so that it extends in the Y direction, the boot washing devices 100 can be stacked.

[0024] As shown in Figure 2, an opening 1a for introducing the boots 50 is provided on the top and front sides of the housing 1. A brush 2 and a cleaning fluid supply unit 3 are also provided inside the housing 1. Note that in Figure 2, the part of the brush 2 that contacts the boots 50 is omitted, and only the rotating shaft 21 is shown.

[0025] As shown in Figure 3, the housing 1 is provided with a mounting section 13 on which the boots 50 can be placed from above. The mounting section 13 is positioned in the vertical direction (Z direction) between a pair of brushes 2 that clean the sides of the boots 50 and a brush 2 that cleans the bottom surface of the boots 50. The mounting section 13 is also positioned below (towards Z2) the cleaning liquid supply section 3. The mounting section 13 is provided with multiple grids, and the cleaning liquid containing sludge falls downward through the gaps in the grids.

[0026] As shown in Figure 4, a tapered inclined surface 1b and a pair of wide inclined surfaces 1c are provided on the lower (Z2 side) side of the interior of the housing 1. The tapered inclined surface 1b has a shape that tapers toward the outlet 4. In plan view, the tapered inclined surface 1b is a triangle or trapezoid that narrows toward the X1 direction. The pair of wide inclined surfaces 1c have an inverse taper shape, with their width (length in the Y direction) increasing toward the outlet 4. The pair of wide inclined surfaces 1c are configured to sandwich the tapered inclined surface 1b from both sides in the Y direction and are inclined downward toward the tapered inclined surface 1b. The wide inclined surfaces 1c are, for example, triangles oriented in the opposite direction to the tapered inclined surface 1b. The tapered inclined surface 1b and the wide inclined surfaces 1c are flat surfaces. The tapered inclined surface 1b is formed from the X2 side to the X1 side, with reference to the center line Y that extends in the Y direction passing through the center of the housing 1.

[0027] As shown in Figure 5, the tapered inclined surface 1b is inclined toward the outlet 4. The inclination angle is not particularly limited, but for example, it is 10 degrees or less. Therefore, as shown in Figures 6 and 7, as you move toward the outlet 4, the position of the tapered inclined surface 1b moves downward and the length in the Y direction of the cross-section decreases. Also, as you move toward the outlet 4, the length in the Y direction of the cross-section of the wide inclined surface 1c increases. Furthermore, in the cross-sectional view cut along the Y direction, the pair of wide inclined surfaces 1c are at the same height, straddling the center line X that extends in the X direction through the center of the housing 1. Also, in the cross-sectional view cut along the Y direction, the tapered inclined surface 1b is located below the center line X. Note that in Figures 6 and 7, the center line X is represented by a circle.

[0028] As shown in Figure 4, the motor 5 is located at the bottom of the housing 1, on the side opposite the discharge port 4 (X2 side). The motor 5 is located on the X2 side of the center line Y and on the Y2 side of the center line X. The motor 5 is covered by a cover member 6.

[0029] As shown in Figure 5, the cover member 6 has an inclined upper surface portion 6a that slopes downward (towards Z2) toward the tapered inclined surface 1b. A step portion 6b is also provided between the inclined upper surface portion 6a of the cover member 6 and the tapered inclined surface 1b. The cover member 6 is made of a water-resistant material, such as stainless steel.

[0030] The brush 2 is mounted in the upper part of the interior of the housing 1 and has a rotating shaft 21 with an end portion 2a (see Figure 2) that protrudes outward from the housing 1. The brush 2 is detachably attached to the housing 1 via the rotating shaft 21. The rotating shaft 21 is supported by a bearing portion 2b and fixed to the housing 1. The bearing portion 2b protrudes outward from the housing 1.

[0031] As shown in Figure 3, the brush 2 is connected to the motor 5 via a drive mechanism 51. The brush 2 is rotated by the motor 5. The brush 2 also includes a pair of brushes 2 for cleaning the sides of the boots 50 and a brush 2 for cleaning the bottom of the boots 50, and the boots 50 are cleaned by the rotation of these brushes 2.

[0032] The cleaning fluid supply unit 3 supplies cleaning fluid to the inside of the housing 1. The cleaning fluid supply unit 3 is connected to an external water supply device, such as a tap water supply (not shown), via piping 31. The cleaning fluid supply unit 3 is a pipe extending in the same direction as the rotation axis 21 of the brush 2, and has multiple holes for supplying cleaning fluid. The cleaning fluid flows down from the holes in a parabolic arc. The cleaning fluid supply unit 3 is positioned so as to sandwich the brush 2 from both ends in the Y direction. The cleaning fluid supply unit 3 is located above the brush 2 (towards the Z1 side). The cleaning fluid may be water or detergent. After being supplied into the housing 1, the cleaning fluid becomes a cleaning fluid containing sludge (dirt) attached to the boots 50, and flows downward through the gaps in the grid of the mounting section 13. The cleaning fluid containing sludge is then collected on the tapered inclined surface 1b by a pair of wide inclined surfaces 1c and an inclined upper surface 6a, and discharged from the discharge port 4.

[0033] As shown in Figure 4, the outlet 4 is located at the bottom of the side surface of the housing 1. The outlet 4 is a through-hole provided for discharging the cleaning fluid to the outside. A drain pipe P (see Figure 1) is attached to the outlet 4. The cleaning fluid supplied into the housing 1 flows from the inclined upper surface 6a and the wide inclined surface 1c of the cover member 6 to the tapered inclined surface 1b.

[0034] As shown in Figure 1, the housing 1 is provided with a water receiving section 1d that receives water flowing to the outer surface of the housing 1 via the rotating shaft 21 and returns the water to the inside of the housing 1. Multiple water receiving sections 1d are provided corresponding to the rotating shaft 21 of the brush 2. The water receiving section 1d is formed by cutting and raising the outer surface of the housing 1 and is a cut-out hole that protrudes outward from the housing 1. Water that flows to the outside along the rotating shaft 21 flows from the rotating shaft 21 along the bearing section 2b or directly to the water receiving section 1d. Then, it is returned to the inside of the housing 1 via the water receiving section 1d. The water receiving section 1d is provided at a position corresponding to the end 2a of the rotating shaft 21, and below the end 2a (towards Z2).

[0035] As shown in Figure 8, the amount of protrusion w1 of the water receiving portion 1d from the outer surface of the housing 1 is less than or equal to the amount of protrusion w2 of the end 2a of the rotating shaft 21 from the outer surface of the housing 1. Also, as shown in Figure 1, the horizontal length w3 of the water receiving portion 1d is greater than or equal to the diameter r of the rotating shaft 21. That is, in the X direction, the area where the water receiving portion 1d is provided overlaps with the entire area where the rotating shaft 21 is provided. The area where the water receiving portion 1d is provided includes both ends of the rotating shaft 21 in the X direction.

[0036] (Effects of the first embodiment) In the first embodiment, the following effects can be obtained.

[0037] In the first embodiment, as described above, the device comprises a housing 1 having an opening 1a for introducing the boots 50 to be cleaned, a brush 2 positioned inside the housing 1 and driven by a motor 5 to clean the boots 50, a cleaning liquid supply unit 3 that supplies cleaning liquid to the inside of the housing 1 during cleaning, and a discharge port 4 located at the bottom of the housing 1 for discharging the cleaning liquid used to clean the boots 50. The lower inside of the housing 1 has a tapered inclined surface 1b that narrows towards the discharge port 4 and slopes downward. This allows the cleaning liquid containing sludge to be collected and discharged from the discharge port 4 without the need for a dust trap. As a result, there is no need to remove sludge accumulated in a dust trap, and the cleaning liquid containing sludge can be efficiently discharged.

[0038] In the first embodiment, as described above, the housing 1 widens towards the discharge port 4 and is configured to sandwich the tapered inclined surface 1b from both sides, and has a pair of wide inclined surfaces 1c that slope downward toward the tapered inclined surface 1b. As a result, even when cleaning liquid is supplied to a wide area inside the housing 1, the cleaning liquid containing sludge can be effectively collected on the tapered inclined surface 1b via the wide inclined surfaces 1c, thereby enabling more efficient discharge of the cleaning liquid containing sludge.

[0039] In the first embodiment, as described above, the motor 5 is positioned at the bottom of the housing 1 opposite to the discharge port 4 and attached to the bottom of the housing 1 opposite to the tapered inclined surface 1b, and is further provided with a cover member 6 that covers the motor 5. This allows the motor 5 to be positioned inside the housing 1, making the boot washing device 100 more compact compared to the case where the motor 5 is located outside the boot washing device 100. In addition, by providing the cover member 6, it is possible to suppress the adhesion of washing liquid to the motor 5 which is positioned inside the housing 1.

[0040] In the first embodiment, as described above, the cover member 6 has an inclined upper surface portion 6a that slopes downward toward the tapered inclined surface 1b, and a stepped portion 6b is provided between the inclined upper surface portion 6a of the cover member 6 and the tapered inclined surface 1b. As a result, the cleaning liquid containing sludge can flow from the cover member 6 to the tapered inclined surface 1b by the inclined upper surface portion 6a and the stepped portion 6b, thereby preventing the cleaning liquid containing sludge from accumulating on the upper surface of the cover member 6.

[0041] In the first embodiment, as described above, the brush 2 is mounted in the upper part of the interior of the housing 1 and includes a rotating shaft 21 having an end portion 2a that protrudes outward from the housing 1. The housing 1 is provided with a water receiving portion 1d that receives water flowing downward along the outer surface of the housing 1 via the rotating shaft 21 and returns the water to the interior of the housing 1. As a result, the water receiving portion 1d can return water (cleaning fluid) that has leaked to the outside of the housing 1 back to the interior of the housing 1 and discharge it from the outlet 4, thereby preventing water from leaking to the outside (outer surface) of the housing 1. Furthermore, by preventing water from leaking to the outside (outer surface) of the housing 1, the user is saved the trouble of removing water that has adhered to the outside of the housing 1.

[0042] In the first embodiment, as described above, the water receiving portion 1d is provided at a position corresponding to the end of the rotating shaft 21 and below the end, and is a cut-out hole that protrudes outward from the housing 1. As a result, the water receiving portion 1d can be formed integrally with the housing 1, eliminating the need to provide it as a separate component, thereby reducing the number of parts and the assembly time.

[0043] In the first embodiment, as described above, the amount of the cut-out hole protruding from the outer surface of the housing 1 is less than or equal to the amount of the end 2a of the rotating shaft 21 protruding from the outer surface of the housing 1. This makes the cut-out hole relatively small, thereby suppressing an increase in the distance between the two outer surfaces (between the two outer ends) in the axial direction of the rotating shaft 21 of the housing 1. This prevents the housing from becoming larger even if a cut-out hole is provided. Furthermore, because the cut-out hole can be made relatively small, it is possible to suppress the spraying of cleaning fluid from the inside of the housing 1 to the outside through the cut-out hole.

[0044] In the first embodiment, as described above, the horizontal length of the water receiving portion 1d along the outer surface of the housing 1 is greater than or equal to the diameter of the rotating shaft 21. As a result, the horizontal end of the water receiving portion 1d is located outside the outer circumference of the rotating shaft 21, so that water leaking to the outside along the outer circumference of the rotating shaft 21 can be reliably received by the water receiving portion 1d, and the water that leaks to the outside can be returned to the inside of the housing 1.

[0045] In the first embodiment, as described above, the housing 1 is made of thin stainless steel sheets joined by rivets, and a waterproofing material is filled into the joints. This allows for increased joint strength through rivet joining. Furthermore, by being made of thin stainless steel sheets, the strength of the boot washing device 100 can be increased while reducing its weight, and multiple boot washing devices 100 can be stacked and stored. In addition, because a waterproofing material is filled into the joints, leakage of cleaning fluid to the outside from the joints can be suppressed.

[0046] [Second Embodiment] Next, with reference to Figure 9, a boot cleaning device 200 according to a second embodiment of the present invention will be described. In this second embodiment, unlike the first embodiment described above, a protective cap 22 is provided at the end 2a of the rotating shaft 21. Components identical to those in the first embodiment are shown in the figure with the same reference numerals, and their descriptions are omitted.

[0047] As shown in Figure 9, in the boot washing device 200 of the second embodiment, a protective cap 22 is attached to the bearing portion 2b that supports the rotating shaft 21. The protective cap 22 covers the end portion 2a of the rotating shaft 21. The shape of the protective cap 22 is not particularly limited.

[0048] The other configurations of the second embodiment are the same as those of the first embodiment described above.

[0049] (Effects of the second embodiment) In the second embodiment, the following effects can be obtained.

[0050] In the second embodiment, as described above, the device comprises a housing 1 having an opening 1a for introducing the boots 50 to be cleaned, a brush 2 positioned inside the housing 1 and driven by a motor 5 to clean the boots 50, a cleaning liquid supply unit 3 that supplies cleaning liquid to the inside of the housing 1 during cleaning, and a discharge port 4 located at the bottom of the housing 1 for discharging the cleaning liquid used to clean the boots 50. The lower inside of the housing 1 has a tapered inclined surface 1b that narrows towards the discharge port 4 and slopes downward. This allows the cleaning liquid containing sludge to be collected and discharged from the discharge port 4 without the need for a dust trap. As a result, there is no need to remove sludge accumulated in a dust trap, and the cleaning liquid containing sludge can be efficiently discharged.

[0051] Furthermore, in the second embodiment, as described above, the brush 2 is mounted in the upper part of the interior of the housing 1 and includes a rotating shaft 21 having an end portion 2a that protrudes outward from the housing 1, and includes a bearing portion 2b that is attached to the outer surface of the housing 1 to support the rotating shaft 21 and protrudes outward from the housing 1, and a protective cap 22 that is attached to the bearing portion 2b and is configured to cover the end portion 2a of the rotating shaft 21. As a result, since the end portion 2a of the rotating shaft 21 is covered by the protective cap 22, it is possible to suppress water from flowing outward along the rotating shaft 21.

[0052] Other effects of the second embodiment are the same as those of the first embodiment described above.

[0053] (modified version) It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects.
