It is equipped with a conveyance roller 8 that rolls in the front-back direction. These conveyance rollers 8 are spaced apart from the floor surface F when the toilet cleaning device 1 is in an upright position as shown in FIG. 2(a).

The frame portion 6 has a U-shape that opens forward in plan view, and the rod portions 7, 7 have moving rollers 9, 9, which are moving means that roll in the left and right lateral directions, at the lower ends thereof. Each is provided. In the standing state of the toilet cleaning device 1 as shown in FIG. It is possible to move horizontally on the top. As shown in FIG. 1, a second cleaning mechanism section 10, which will be described in detail later, is attached to the frame section 6.

As shown in FIGS. 1 and 2, an upright frame (erected section) 11 is fixed to the base 5 of the truck section 4 and stands upright. The standing frame 11 includes a lower frame 12 fixed to the base 5 and an upper frame 13 connected to the upper end of the lower frame 12 via a joint 14.

As shown in FIG. 4(b), the lower frame 12 is a metal frame that is curved so that both ends 12a serve as upper ends, forming a substantially U-shape. It is provided with moving auxiliary rollers 15, 15. These auxiliary rollers 15 are spaced apart from the floor surface when the toilet cleaning device 1 is in an upright position, and are located above the conveyance rollers 8 (see FIG. 2(b)). These conveying rollers 8 and auxiliary rollers 15 constitute a conveying means.

The joint portion 14 can rotate within a range where the lower frame 12 and the upper frame 13 form a right angle, that is, 90 degrees at maximum. Further, although not described in detail here, the joint portion 14 has a built-in braking means such as a rotary damper, so that the relative rotation of the lower frame 12 and the upper frame 13, that is, the bending of the standing frame 11, is moderated. In addition, the bending angle of the lower frame 12 and the upper frame 13 can be adjusted steplessly.

The cover body 2 is connected at its upper side to the upper end 13a of the upper frame 13 via shaft portions 16, and is supported by the upright frame 11. Further, although not described in detail here, the shaft portion 16 includes an angle maintenance mechanism that maintains the relative angle between the cover body 2 and the upper frame 13. Note that the angle maintaining mechanism may be one that maintains the horizontal state of the cover body 2.

Further, an operating handle 17 is fixed to the joint portion 14, and by rotating the operating handle 17 upward as shown in FIG. 2(b), the upper frame 13 is rotated downward. The cover body 2 is moved forward and diagonally downward.

As shown in FIG. 3, the cover body 2 is made of translucent synthetic resin, and has an opening 20 (see FIG. 1) that opens continuously at the front and the bottom. Further, the cover body 2 includes a cover body 18 connected to the upper frame 13, and a lid body 19 rotatably connected above the cover body 18 by a hinge portion 21.

The cover main body 18 has left and right side parts 18a, 18a and a back part 18b and is open to the front, upward and downward, and the lid body 19 has left and right side parts 19a, 19a and a top part 19b. The opening 20 formed by the cover body 18 and the cover body 19 can be expanded by rotating the cover body 19 at the hinge portion 21 .

In addition, translucent synthetic resin wings 22 are attached to the inner side of the facing portions of the side surfaces 18a of the cover body 18 and the side surfaces 19a of the lid body 19. Regardless of the degree of opening of the opening 20 formed by the side surface portions 18a and 19a, the area separated from each other by the side surface portions 18a and 19a can be shielded.

As shown in FIG. 4(a), a motorized device 25 is attached to the cover body 2. As shown in FIG. The electric device 25 includes an operation panel (not shown) exposed on the outer surface of the cover body 2, and also includes a battery and a control board (both not shown), and is further connected to the battery and control board and arranged inside the cover body 2. The first cleaning mechanism section 3 is equipped with a first cleaning mechanism section 3.

As shown in FIG. 1, the first cleaning mechanism section 3 includes a brush 31 that is dimensioned to fit inside the cover body 2 in the vertical direction and has a longitudinal length in the vertical direction, and drives this brush 31 in forward and reverse rotation in the horizontal direction. It includes a motor (driving means) not shown, and a lifting arm 32 that moves the brush 31 and the motor up and down. The motor and the lifting arm 32 receive power from a battery (not shown), and their operations are controlled by a control board.

Although not detailed in the figure, the brush 31 has bristles extending in the radial direction from the rotating shaft, and has bristles that extend upwardly at the upper end and bristles that extend downwardly at the lower end. . As shown in FIG. 7, the lower end of the brush 31 is detachable as a hemispherical lower end brush 33, and the bristle material attached to this lower end brush 33 covers the bristle material at the lower end of the brush 31. It consists of

As shown in FIG. 1, the second cleaning mechanism section 10 includes a rotating brush 35 having a rotating shaft in the front-rear direction, a motor (driving means) 37 (see FIG. 2) that drives the rotating brush 35 in forward and reverse rotation, and It includes a lifting mechanism 36 that lifts and lowers the rotating shaft. The motor 37 and the lifting mechanism 36 of the second cleaning mechanism section 10 are powered by a battery (not shown), and their operations are controlled by a control board.

Although not shown in detail in the drawings, the elevating mechanism 36 includes a holder that pivotally supports a rotating shaft that can be guided along a rail that extends in the vertical direction, and a belt and a pulley that extend parallel to the rail. By having a holder attached to the belt, the rotary brush 35 and motor 37 are moved up and down via the holder by forward and reverse driving of the belt drive motor.

Further, the elevating mechanism 36 is attached to the center portion of the rear end portion 6a of the frame portion 6 in the left-right direction. The rotating brushes 35, 35 are arranged so as to be inclined in a V-shape in a plan view so that the rear ends on the motor 37 side are close to each other and the free ends are spaced apart from each other. The elevating mechanism 36 is disposed slightly forward of the cover body 2 that has been lowered to the lower end position, and is located inside the cover body 2 that has been lowered to the lower end position.

Next, the cleaning work performed by the toilet cleaning device 1 will be explained using FIG. 4. The urinal U in this embodiment is supported by a wall W, and its lower end is spaced apart from the floor F, and there is a space below the urinal U.

As shown in FIG. 4(a), first, the cleaning worker grasps the operation handle 17 of the toilet cleaning device 1 and tilts the toilet cleaning device 1 backward. As a result, the moving roller 9 moves away from the floor surface F, and the conveyance roller 8 and the auxiliary roller 15 come into contact with the ground. In this state, the cleaning worker moves the toilet cleaning device 1 forward toward the urinal U. At this time, the toilet cleaning device 1 is moved until the front ends of the rod parts 7, 7 of the frame part 6 come into contact with or come close to the wall surface W.

Next, by raising the toilet cleaning apparatus 1 forward from the state in which the toilet cleaning apparatus 1 is brought close to the urinal U, as shown in FIG. The moving roller 9 is moved away and the moving roller 9 touches the ground instead, and the toilet cleaning device 1 is placed in an upright position.

After the toilet cleaning device 1 is in the standing position, the cleaning worker rotates the operating handle 17 upward and moves the cover body 2 forward and diagonally downward. The cover body 2 covers the urinal U from diagonally above, and the cleaning worker can check the urinal U when the opening edge 18c of the cover body 18 comes into contact with the wall W (FIGS. 2(b) and 3(a), b)) to stop the rotation of the operating handle 17 (see Fig. 4(c)).

At this time, since the cover main body 18 is opened downward, it can cover up to the lower end of the urinal (covering operation) without interfering with the drip receptacle U2 of the urinal. Further, as shown in FIG. 2(b) and FIGS. 3(a) and (b), the lid body 19 constituting the cover body 2 comes into contact with the upper end of the urinal U while the cover body 2 is moving, The lid body 19 rotates about the hinge portion 21 relative to the cover body 18, and the opening 20 of the cover body 2 is expanded. In this way, the opening 20 of the cover body 2 is adjusted within the rotatable range of the cover body 19, so that the upper and lower portions of the urinal differ depending on the specifications, as shown in FIGS. By adjusting the opening 20 (see FIG. 1) of the cover body 2 according to the dimensions, it is possible to effectively prevent water from splashing around the urinal during cleaning work.

As shown in FIG. 4(c), after the urinal is completely covered with the cover body 2, the cleaning worker presses a toilet cleaning start button (not shown) provided on the operation panel. A control board (not shown) of the electric device 25 starts the toilet cleaning operation by the first cleaning mechanism section 3 in response to the depression of the toilet cleaning start button. In the first cleaning mechanism section 3, a brush 31 is disposed inside the urinal U in a state where the covering of the cover body 2 is completed, and the rotational drive of the brush 31 and the vertical movement of the vertical arm 32 are controlled. , the inner wall surface U1 of the urinal U is cleaned. Further, the bottom part (not shown) of the drip receiver U2 is also cleaned by the lower end brush 33 of the brush 31.

During this cleaning, water is supplied into the urinal U by covering the water discharge sensor US of the urinal U with the cover body 2, so this water is used to clean the inside of the urinal U. It can be carried out. Note that cleaning liquid can be appropriately supplied to the brush 31 from the cleaning liquid tank 5b.

Further, upon receiving the depression of the toilet bowl cleaning start button, the control board causes the first cleaning mechanism section 3 to start the toilet bowl cleaning operation, and at the same time, starts the toilet bowl cleaning operation by the second cleaning mechanism section 10. As shown in FIG. 6, in the toilet cleaning operation, the second cleaning mechanism section 10 rotates the rotary brushes 35, 35 and drives the rotary brushes 35, 35 and motors 37, 37 up and down by the lifting mechanism 36, 36. . The rotating brushes 35, 35 are moved up and down about 80 cm above, with the inner side of the rod parts 7, 7 of the frame part 6 as the lowest end, that is, the upper end U3 of the drip catcher U2 of the urinal U as the uppermost end.

The rotating brushes 35, 35 are arranged at an angle so as to have a V-shape when viewed from above, so that they can protect the outside edge of the drip receptacle U2 of the urinal, which is tapered toward the front side when viewed from above, and the dripping brushes. Since the rotary brushes 35, 35 have their longitudinal ends along the outer surface U4 of the lower end of the urinal U along the outer shape of the receiver U2 and come into wide contact, cleaning can be carried out efficiently. Further, although not explained in detail in the drawings, since the rotating brushes 35, 35 of the second cleaning mechanism section 10 have long bristles, the upper surface of the edge, which is the upper end U3 of the drip receiver U2, can also be cleaned at the same time. During this cleaning, water is appropriately supplied from the water tank 5c and cleaning liquid from the cleaning liquid tank 5b to the rotating brushes 35, 35, respectively.

When the toilet bowl cleaning operation by the first cleaning mechanism section 3 and the second cleaning mechanism section 10 is completed, the control board notifies the user of the completion by displaying a predetermined display on the operation panel, for example. After confirming the completion notification, the cleaning worker rotates the operating handle 17 backward and downward, as shown in FIG. 5(b). As a result, the cover body 2 is moved rearward and diagonally upward and retreated from the urinal U (cover release operation).

After the cover body 2 has been completely retracted, the cleaning worker presses a floor cleaning button (not shown) provided on the operation panel. A control board (not shown) of the electric device 25 starts the floor cleaning operation by the second cleaning mechanism section 10 in response to the pressing of the floor cleaning button.

During the floor cleaning operation, the control board does not operate the lifting mechanism 36 of the second cleaning mechanism section, and during the toilet cleaning operation, the rotating brushes 35, 35 are moved inside the rod sections 7, 7 of the frame section 6 at the lowest end. While maintaining their respective positions, the control board rotates the rotating brushes 35, 35. A cleaning worker moves the toilet cleaning device 1 laterally during floor cleaning operation. Specifically, the cleaning worker moves the toilet cleaning device 1 laterally using the moving rollers 9 while the front ends of the rod portions 7, 7 of the frame portion 6 of the trolley portion 4 are in contact with or close to the wall surface W.

As described above, the floor cleaning operation is performed after the cover body 2 has been completely retracted. As shown in FIG. 2(a), the cover body 2 is located at the front end U6 of the side wall above the drip tray U2 of the urinal U and above the drip tray U2 of the urinal U (see FIG. 2(a)). It is retracted further back than the urinal U, so that it does not interfere with the urinal U when the toilet cleaning device 1 moves laterally.

In the floor cleaning operation, the floor surface F is cleaned by the rotating brushes 35, 35 of the second cleaning mechanism section. In addition, the rotating shafts of the rotating brushes 35, 35 are moved laterally at approximately the center in the vertical direction between the lower end surface U7 of the urinal U (see FIG. 2(a)) and the floor surface F, and At the same time as cleaning the floor surface F between the urinal U' and the urinal U', cleaning of the lower end surface U7 of the urinal U and the lower end surface U7 of the adjacent urinal U' can also be completed.

The cleaning worker is in a state where the frame part 6 of the trolley part 4 is located below the neighboring urinal U', that is, the horizontal movement direction side of the rod parts 7, 7 forming the frame part 6 is the neighboring urinal U'. When the toilet cleaning device 1 is completely exposed in the lateral movement direction beyond the lower end surface U7, it is determined that the lateral movement of the toilet cleaning device 1 to the initial position relative to the adjacent urinal U' is completed, and the floor cleaning button provided on the operation panel is pressed. (not shown) is pressed again to stop the floor cleaning operation.

Then, after completing the horizontal movement of the toilet cleaning device 1, the cleaning worker rotates the operating handle 17 upward to cover the adjacent urinal U' with the cover body 2, and presses the toilet cleaning start button. do. For the second and subsequent urinals, the toilet cleaning device 1 is moved laterally while performing the floor cleaning operation, thereby cleaning the underside of the urinal and the floor below the urinal before starting the toilet cleaning operation. has been completed, and when the toilet cleaning device 1 is laterally moved to the initial position relative to the next urinal, the floor cleaning operation is continued until the second cleaning mechanism 10 comes out from the bottom of the urinal on the near side. It is not necessary to do this.

In this way, cleaning work for a plurality of urinals attached to the same wall surface W can be performed continuously by moving the toilet cleaning device 1 laterally.

As explained above, since the cover body 2 of the toilet cleaning device 1 in this embodiment is movable in the rear direction relative to the trolley part 4, only the cover body 2 is moved toward the urinal U, leaving the trolley part 4. After the cover body 2 is evacuated from the urinal U side, the toilet cleaning device 1 is moved by the moving means to the front of the next urinal U'. It can be moved laterally, and the urinal U' can be covered by moving the cover body 2 forward again with respect to the trolley part 4. In this way, the toilet cleaning device 1 can continuously and efficiently perform the cleaning work of a plurality of urinals lined up side by side.

Further, the upright frame (erected part) 11 that supports the cover body 2 can be bent back and forth at a joint part 14 arranged at the center in the vertical direction, and this bending allows the cover body 2 to be made smaller. By retreating diagonally upward from the toilet bowl U, the drip tray U2 of the urinal U that protrudes forward can be avoided upward, and the amount of backward movement of the cover body 2 can be reduced to facilitate the uncovering operation and covering. Operations can be performed quickly. Furthermore, since the cover body 2 is attached from above toward the urinal U toward the front and obliquely downward, sliding contact between the wall surface W and the cover body 2 can be prevented, and the workability of height adjustment is excellent.

The elevating mechanism 36 of the second cleaning mechanism section is attached to the rear end 6a of the frame section 6 of the truck section 4, which is U-shaped and opens forward in plan view. The front end thereof is in contact with the wall surface W and is located behind the drip receptacle U2 of a general urinal so as not to interfere with the toilet cleaning device 1 when it moves laterally.

Furthermore, since the brush 31 of the first cleaning mechanism section 3 has a longitudinal length in the vertical direction, the inner wall surface U1 of the urinal U can be efficiently cleaned. Further, since the brush 31 has bristles extending upward at the upper end, it can simultaneously clean the ceiling surface and water spouting part (not shown) inside the urinal U.

Since the cover body 2 is connected to the trolley part 4 so as to be movable up and down, the height of the cover body 2 can be adjusted according to the height position of the drip tray U2 of the urinal U, and the height of the cover body 2 can be adjusted to match the height of the drip tray U2 of the urinal U. Prevents water from splashing. Further, the height of the cover body 2 can be easily adjusted by operating the operating handle 17 attached to the joint portion 14 of the upright frame 11.

Since the vertical dimensions of the urinal U vary depending on the specifications, it is necessary to prepare a large cover body to accommodate many urinals. However, as the cover becomes larger, there is a problem that when cleaning a small urinal, water may splash inside the cover onto the walls and floor around the urinal. By rotating the lid body 19 of the toilet cleaning device 1 in the example with respect to the cover body 18, the opening @20 formed by the cover body 18 and the lid body 19 can be opened according to the specifications and vertical dimensions of the urinal. can be expanded and can effectively prevent water from scattering.

In addition, since the hemispherical lower end brush 33 constituting the lower end of the brush 31 of the first cleaning mechanism section 3 is removable, the lower end brush is pressed against the bottom surface of the drip tray U2 of the urinal U and is subject to heavy wear and tear. Only 33 can be replaced.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any changes or additions that do not depart from the gist of the present invention are included in the present invention. It will be done.

For example, by installing a water receiving means on the frame part 6 of the trolley part 4 or the lower end of the cover body 2, it is possible to collect water especially when cleaning the outer wall part of the urinal U and prevent the floor surface from getting wet.

Further, the first cleaning mechanism section 3 may simultaneously drive a brush that cleans the outer wall portion, in addition to the brush 31 that cleans the inner wall surface U1 during the toilet cleaning operation.

Further, the elevating mechanism 36 of the second cleaning mechanism section 10 may be configured to be able to move up and down to the upper end of the outer wall of the urinal U with the rotating brush 35 at the uppermost position.

Furthermore, since the elevating mechanism 36 of the second cleaning mechanism section 10 can move the rotary brush 35 in the vertical direction, the elevating mechanism 36 slightly reciprocates the rotary brush 35 in the vertical direction during floor cleaning operation. It is also possible to effectively clean the lower end surface U7 of the toilet bowl U.

Alternatively, the outer wall of the urinal U may be cleaned by omitting the elevating mechanism 36 of the second cleaning mechanism section 10 and moving a rotating brush different from the rotating brush 35 up and down within the cover body 2. good.

Further, in the above embodiment, the cover body 2 is movable diagonally upward and rearward with respect to the trolley portion 4, but the cover body 2 is not limited to this, and the cover body 2 is movable at least backwardly with respect to the trolley portion 4. It is fine as long as it is.

Further, the cover body 2 is not limited to being divided into two parts, the cover body 18 and the lid body 19, but the cover body 18 and the lid body 19 may be integrated, or on the contrary, it may be divided into three or more parts. .

In addition, the first cleaning mechanism section 3 is not limited to the brush 31 having a rotating shaft in the vertical direction, but may also be a brush having a rotating shaft in the front-back direction, or may be configured using another cleaning technique such as high-pressure washing. You can.

Further, by detecting the height position of the lower end surface U7 of the urinal U using a sensor, for example, and adjusting the height position of the rotating brush 35 of the second cleaning mechanism section 10 during floor cleaning operation, The lower end surface of the urinal may be reliably cleaned regardless of the height at which the urinal is installed.
