[Industrial applications]

 The present invention relates to a floor surface processing device for cleaning a floor surface and other processing by a processing means such as a rotating brush.

[0002]

[Prior Art and Problems to be Solved]

 As a floor surface treatment device for cleaning a relatively large floor surface such as a building or a factory by driving a processing means such as a rotating brush with an electric motor, it is possible to freely move on the floor surface by, for example, wheels. It is known that a relatively large and therefore relatively heavy storage battery, cleaning solution tank, sewage suction tank, sewage tank, electric motor, etc. are mounted on a trolley as compactly as possible, and the whole is covered with a cover. Since the storage battery in this case is heavy, it is installed almost at the bottom. If a storage battery is used, the workability of the power cord is not reduced and the labor of replacing the power cord is not required, so the efficiency of floor surface treatment work can be increased. On the other hand, the storage battery requires maintenance such as recharging and checking / replenishing the battery fluid each time it is used for a predetermined time, and must be replaced when it reaches the end of its life.

In a conventional floor surface treatment apparatus, when frequently performing necessary maintenance or replacement of a storage battery, the weight of the storage battery is heavy. In addition, those tanks and the like had to be lifted together with the cover to carry out the work, which was extremely complicated. Especially in the case of replacement, the heavy storage battery mounted inside the device had to be lifted and taken out, and a new storage battery had to be mounted, making the work even more difficult. The present invention has been made in view of the above problems existing in the prior art. The purpose of the present invention is to perform work such as maintenance and replacement of the voltage source, which is performed outside the device. It is to provide a floor surface treatment device that can be easily pulled out to perform efficiently.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a floor surface processing apparatus of the present invention is a processing means for processing a floor surface, a road surface, etc., an electric motor for driving the processing means, and a motor for driving the electric motor. A floor surface processing device that has a voltage source and a moving part that is equipped with the voltage source and can move freely on the floor surface, road surface, etc., and can be extended in a substantially horizontal direction. In this state, the base part is supported by the moving part in the projecting state to support the voltage source drawn from the moving part, and one end is on the end side of the voltage source supporting member. It has two support leg members rotatably supported and a connecting means capable of connecting the both support leg members. The both support leg members and the connecting means are housed in the moving part together with the voltage source support member, and are projected. At least the end side of the voltage source support member in the state By both supporting Jiashi member distance between the support leg members each other tint direction downward are connected by the connecting means in a state in which flared at the end, it is assumed that can support against the floor surface, road surface or the like. Further, the voltage source support member may be supported at the base portion so as to be rotatable with respect to the moving portion at least between a protruding state in a substantially horizontal direction and a vertically stored state.

[0005]

[Action]

 According to the first aspect of the present invention, the voltage source supporting member is projected in a substantially horizontal direction, and both supporting leg members are rotated by necessary amounts, respectively. The base side of the voltage source support member is supported by the moving part by connecting both support leg members with the connecting means, and the end side of the voltage source support member is connected by both support leg members. It can be reliably supported. In this way, the voltage source can be pulled out from the moving portion onto the voltage source supporting member that is supported in a state of being projected from the apparatus, and thus, it is possible to prepare for the work such as maintenance and replacement of the voltage source.

After the voltage source drawn out on the voltage source supporting member or the voltage source newly placed by the replacement is mounted on the moving part, the coupling by the coupling means is released and the both supporting leg members are respectively separated. By rotating as much as necessary and accommodating in the moving part together with both supporting leg members and the connecting means, it is possible to prepare for the processing work of the floor surface and the like.

According to the second aspect of the invention, the voltage source support member in the vertically stored state can be made to project substantially horizontally by rotating it by about 90 degrees, and the voltage source supporting member can be rotated about 90 degrees in the opposite direction to turn on the electric power. By setting the pressure source support member in the vertical state, the pressure source support member can be housed in the moving part together with both the supporting leg members and the connecting means.

【Example】

 Embodiments of the present invention will be described with reference to the drawings. In each of the drawings, as one embodiment of the present invention, a detergent is sprinkled on the central portion of the rotary pad in the front part to clean the floor surface by the rotary pad, and a desorber arranged behind the main body of the apparatus. This is a floor cleaner that absorbs used detergents. Among them, FIG. 1 is a schematic front view of the entire apparatus, FIG. 2 is a schematic plan view thereof, FIG. 3 is a schematic side view of the right side thereof, and FIGS.

The movable support base 10 (an example of a moving unit) is supported by wheels 12 and free wheels 14 so as to be movable on the floor, that is, can be moved back and forth and can be turned by the free wheels 14. Posts 16 are erected on both sides of the front of the movable support base 10, and a horizontal support shaft 18 is rotatably supported at the upper end of the posts 16. The base of the operation lever 19 is fixed to one end (the upper end in FIG. 2) of the horizontal support shaft 18. Reference numeral 20 is a handle located at the end of the operation lever 19. The horizontal support shaft 18 is rotated by moving the handle 20 up and down. Reference numeral 21 is a column that is erected on the movable support base 10, and reference numerals 22 and 23 are holding members for holding the operation lever 19 at the upper position and the lower position, respectively.

Reference numeral 24 is a support frame. The support frame 24 is formed by connecting columns 26 standing upright on both sides of the rear end, and a bearing unit 28 whose ends are fixed to the connecting columns 26 and whose base is rotatably supported by the horizontal support shaft 18. It is supported on the movable support base 10 so as to be vertically swingable. Reference numeral 30 is a guide pillar that is erected on the support frame 24, and 32 is a connecting member that connects the upper ends of both guide pillars 30. The tip of the operating lever 34 is inserted below the connecting member 32 between the two guide columns 30. The base of the operating lever 34 is fixed to the horizontal support shaft 18 and swings up and down as the horizontal support shaft 18 rotates.

Reference numeral 36 is a compression coil spring fitted onto both guide columns 30. The lower end of the compression coil spring 36 is in contact with the upper surface of the support frame 24, and the upper end of the compression coil spring 36 is located below the tip of the operating lever 34. Reference numeral 38 denotes a drive motor (electric motor) supported on the support frame 24. A drive pulley (not shown) is fixed to an output shaft (not shown) of the drive motor 38, and a drive belt 41 is stretched over the drive pulley and the driven pulley 40. . The rotation and stop of the drive motor 38 are performed by various well-known ordinary switches 37, and the circuit is closed only when the switch is normally open and when the switch is pressed. For example, a spring or an electronic means is used by releasing the press. It is also performed by the inching switch 39 which immediately opens the circuit. As another example of the inching means, there is one in which a timer circuit or the like is used so that when the switch is pressed once, the circuit is closed for a certain short time.

Reference numeral 42 denotes a rotary pad (an example of a processing unit) for cleaning the floor, which has a circular plane shape. A rotary driving force transmission portion (described later) coupled to the driven pulley 40 is coupled to a coupling portion 44 fixed to an upper center of the rotation pad 42, so that the rotation pad 42 is rotationally driven. As the processing means, various things such as a rotating brush can be applied in addition to the rotating pad. Reference numeral 46 is a support member hanging from the support frame 24, 48 is a swing member supported swingably with respect to the support member 46, and 50 is a swing shaft thereof. A wheel 52 (contact means having low friction) is rotatably provided at an intermediate portion of the swinging member 48, and a weight 54 is fixed to an end of the swinging member 48. 55 is a rotating shaft of the wheel 52. The weight 54 presses the wheel 52 against the upper surface of the rotating pad 42, and a substantially downward load is applied to the rotating pad 42 at its contact point. Reference numeral 56 is a receiving member for receiving the weight 54 at the lower end portion 56a bent into a hook shape when the rotary pad 42 is replaced.

The direction of the rotation axis of the rotation pad 42 is movable as described later. That is, it can be tilted in any direction to some extent. Therefore, the wheel 52 applies a downward load from the weight 54 or the like to the rotating pad 42 at a substantially constant position with respect to the support frame 24, so that the rotation axis of the rotating pad 42 is moved to the loading position with respect to the floor surface. The rotary pad 42 can be rotated while maintaining a slight inclined state toward the front. Then, due to the imbalance of the frictional force between the floor surface and the rotary pad 42, in the illustrated example, a driving force forward is generated. Therefore, for example, even when the weight of the device is heavy, it is easy to move the device in the predetermined direction while performing processing on the floor surface or the like. Further, since the movable rotation axis of the rotation pad 42 is slightly inclined due to the loading of a load, the slight inclination of the rotation axis can be maintained to some extent even on a floor surface or the like that has irregularities or changes in inclination. Can be maintained. Therefore, the ease of movement is not greatly hindered by such changes in the floor surface.

It should be noted that the position where the downward load is applied can be made variable with respect to the entire device by moving the position where the load is applied to the rotary pad 42 or by providing a plurality of loading means and making an appropriate selection. Then, the device can be easily moved in the required direction. Further, the inclination of the rotation axis can be realized, for example, by maintaining the rotation axis itself in an inclined state. Also in this case, the driving force in the predetermined direction can be obtained. Reference numeral 58 is a rubber plate for preventing the cleaning water and the like from being scattered backward by the rotary pad 42, and 60 is a movable cover attached to the support frame 24 to cover the rotary pad 42 and its drive system. . When the handle 20 and the operating lever 19 are in the intermediate position shown by the solid line in FIG. 1, the rotary pad 42 is pressed against the floor surface by the weight of the rotary pad 42, the drive system connected thereabove, and the movable cover 60. To do.

When the handle 20 is lifted and the operation lever 19 is held by the holding member 22, the operation lever 34 swings downward and presses the compression coil spring 36 downward, as shown in FIG. Due to the elastic force generated by the compression of the compression coil spring 36, the rotary pad 42 is elastically pressed against the floor surface via the support frame 24 and the like. Then, the reaction force is supported on the movable support base 10 via the horizontal support shaft 18 and the holding member 22. Therefore, depending on the treatment mode and the material of the floor surface, for example, it is possible to improve the treatment efficiency such as dirt removal by overpressure contact, or to perform the appropriate treatment so as to protect the floor surface without applying overpressure. is there. In addition, since the rotary pad 42 can move up and down while maintaining the pressure contact state by adapting to the inclination and unevenness on the floor surface, it can also exhibit the effect of preventing uneven processing.

It should be noted that, for example, by providing a plurality of steps at a position where the operation lever 19 is held upward, the magnitude of the pressing force that causes the rotary pad 42 to pressurize the floor surface via the compression coil spring 36 is determined by the compression coil spring. By changing the degree of deformation of 36 so that it can be changed in a plurality of stages, the magnitude of the overpressure contact force can be appropriately selected according to the mode of treatment, and the treatment can be performed more effectively. Next, when the handle 20 is pushed down and the operation lever 19 is held by the holding member 23, the operation lever 34 swings upward as shown in FIG. 5, and the support frame 24 via the connecting member 32 and the guide pillar 30. The state where the rotary pad 42, the movable cover 60, and the like are lifted is maintained. In this state, the rotating pad 42 can be easily replaced.

An upper end of a vertical portion of the connecting member 62 is connected to the movable support base 10 via a rotating shaft 64, and a suction device 68 is connected to a rear end of a horizontal portion of the connecting member 62 via a rotating shaft 66. Has been done. A tension coil spring 72 is mounted between the front portion of the lower end of the vertical portion of the connecting member 62 and the projection 70 that hangs from the movable support base 10 in front of the vertical portion. The pulling force causes the clockwise moment in FIG. 1 to act on the connecting member 62 to enhance the followability of the sucker 68 to the floor surface. FIG. 6 is a bottom view of the main part of the suction device 68, and FIGS. 7 and 8 are schematic cross-sectional views of the suction device 68. 74 is a top plate, and 76 is a suction port member fixed to the lower surface of the top plate 74.

The support plates 84 and 88 have a vertical length shorter than that of the front blade 86, and their lower ends are located above the floor surface 92. The support plates 84 and 88 are in contact with the front and rear surfaces of the front blade 86 to prevent the front blade 86 from excessively bending, and thus generate a supporting force for supporting the sucker 68 on the floor surface 92. The lower ends of the support plates 84 and 88 are positioned above the floor surface 92 because the lower end of the front blade 86 moves back and forth while being in contact with the floor surface 92, so that the lower portion of the front blade 86 is easily bent. is there. A rear blade 94, a support plate 96, and a pressing plate 98 are provided on the rear surface of the rear hanging portion 76a so as to be stacked rearward in this order.

Reference numeral 115 shown in FIG. 3 denotes a weight 117, which is a circular cup-shaped cushioning member that covers the weight 115, and is supported by a bolt 127 so as to be rotatable with respect to the top plate 74. The cushioning member 117 extends forward and backward and outward at both ends of the top plate 74, thereby exerting a cushioning action between the wall surface and the sucker 68. If a hard material is used for the front blade 86 and the rear blade 94 to suppress wear, there is a risk that sufficient bending may not be obtained or the floor surface 92 may not be contacted over the entire length. By preventing it. In addition, 128 is a notch provided at intervals at the lower edge of the support plate 96, and the notches are also provided in the support plate 84 and the support plate 88. Further, the connecting member 62 can be configured to be swingable in a horizontal plane about its vertical portion so that the position of the suction device 68 can be adapted to the surrounding conditions.

As shown in FIG. 7, by moving the sucker 68 forward, the front blade 86 bends backward due to the friction with the floor surface 92, and the groove 105 between the front blade 86 and the floor surface 92. Form a void in the. By sucking through the suction hole 82, the substance to be sucked such as detergent on the floor 92 and / or the outside air is sucked toward the suction port 78 through the gap. Therefore, when moving forward, the used detergent on the floor surface 92 is sucked through the gap formed by the concave groove 105 of the front blade 86. The object to be sucked is not limited to fluid such as liquid or gas. It also includes solids such as granules. The rear blade 94 bends rearward due to friction with the floor surface 92, and the base portion 107 of the blade 94 and the floor surface 92 are brought into close contact with each other. Therefore, during the forward movement, the used detergent taken between the rear blade 94 and the front blade 86 through the gap formed by the concave groove 105 of the front blade 86 is prevented from escaping between the rear blade 94 and the floor surface 92. , It is possible to prevent the material to be sucked from being left behind.

As shown in FIG. 8, when the suction device 68 is moved rearward, the rear blade 94 is bent forward due to the friction with the floor surface 92, and the recessed groove 111 has a space between it and the floor surface 92. To form. By sucking through the suction hole 82, the substance to be sucked such as detergent on the floor 92 and / or the external air is sucked toward the suction port 78 through the gap. Therefore, when moving backward, the used detergent on the floor surface 92 is sucked through the space formed by the concave groove 111 in the rear blade portion. Further, the front blade 86 bends forward due to the friction with the floor surface 92, and the substrate portion 101 of the front blade 86 and the floor surface 92 are brought into a close contact state. Therefore, at the time of moving backward, it is possible to prevent the sucked matter taken between the rear blade 94 and the front blade 86 from escaping from between the front blade 86 and the floor surface 92.

As shown in FIG. 3, the operator cannot see the lower part of the support frame 24 from the rear, but the center of rotation of the rotary pad 42 is eccentric to the right from the midpoint of the width of the main body of the device. Since the position of the protruding portion of the rotary pad 42 to the right side of the main body of the apparatus can be visually recognized, the operator of the apparatus can easily grasp the processing situation by the rotary pad 42, and the processing work can be smoothly and reliably performed. Moreover, since the protruding portion of the rotary pad 42 from the main body of the device is not on both sides but on one side, the rotary pad 42 is prevented from being upsized, the torque required for the drive motor 38 is suppressed, and the rotary pad 42 also protrudes to the front of the main body. It is also adaptable for use in complicated places and on the walls.

FIG. 10 is a fragmentary cross-sectional view of the rotating pad 42 and its peripheral portion. Reference numeral 163 is a mortar-shaped recess provided in the support frame 24. A hollow fixed shaft 165 is connected to the lower part of the central portion of the mortar-shaped recess 163, a detergent introducing pipe 167 is inserted into the hollow fixed shaft 165 from the central bottom of the mortar-shaped recess 163, and the detergent supply pipe 153 is connected. The upper end portion of the detergent introducing pipe 167 is protruded upward from the central bottom portion of the mortar-shaped recess 163. Therefore, the detergent introduced from the detergent supply pipe 153 into the hollow fixed shaft 165 through the detergent introduction pipe 167 is sprinkled on the floor surface at the central portion of the rotary pad 42 from the lower opening 165a. Reference numeral 169 is a rotary drive force transmission portion rotatably supported on the outer peripheral side of the hollow fixed shaft 165 via ball bearings 171 and 173.

The driven pulley 40 has a tray shape with an open central bottom, and a drive belt 41 is wound around the outer peripheral surface thereof. When the drive belt 41 is circularly driven by the drive motor 38, the rotary drive force transmission unit 169 rotates around the hollow fixed shaft 165 integrally with the driven pulley 40.

FIG. 11 is a plan view of the rotational driving force transmitting portion 169, FIG. 12 is a side view thereof, and FIG. 13 is a sectional view taken along line XIII-O-XIII in FIG. The rotational driving force transmitting portion 169 has a cup shape with an open bottom, and the lower outer peripheral surface is formed as a convexly curved surface 175 having a rotationally symmetrical shape that is obliquely downwardly convex. Reference numeral 177 is a protrusion having an elliptical cross-section that protrudes radially outward from the outer peripheral surfaces of the upper and lower intermediate portions. The protrusion 177 is provided in a two-fold rotational symmetry. It should be noted that the protrusion of the protrusion 177 may have a component other than the outward radial direction, for example, a component in the vertical direction. The connecting portion 44 includes an inner shell portion 179 and an outer shell portion 181. 14 is a plan view of the inner shell portion 179, FIG. 15 is a side view thereof, FIG. 16 is a rear view thereof, and FIG. 17 is a sectional view taken along line XVII-XVII in FIG.

The inner shell part 179 made of a soft resin material such as synthetic resin has a bowl shape in which the inner peripheral surface of the peripheral wall 180 is formed by a rotationally symmetric concave curved surface 183 that is convex downward. Is open. Reference numeral 185 is a receiving projection that is provided outwardly in a two-fold rotationally symmetrical manner, and 187 is a receiving surface that receives the circumferential forward rotation direction side of the protruding portion 177. On the back side of the receiving surface 187 of the receiving protrusion 185, a plurality of concave grooves 189 are provided in the vertical direction. 18 is a plan view of the outer shell portion 181, FIG. 19 is a side view thereof, FIG. 20 is a sectional view taken along line XX-XX in FIG. 18, and FIG. 21 is a sectional view taken along line XXI-XXI in FIG. FIG. 19 is a sectional view taken along the line XXII-O-XXII in FIG. 18. The aluminum die-cast outer shell portion 181 has a cylindrical portion 193 having a flange portion 191 on the outer peripheral side, and a bowl-shaped portion 195 having a bottom opening located inside at a radial distance from the cylindrical portion 193. An inner peripheral surface of the lower portion of the bowl-shaped portion 195 is formed by a rotationally symmetrical concave curved surface 197 that is convex downward. Reference numeral 199 is a drop-out preventing portion that extends inward from a part of the upper end portion of the cylindrical portion 193, and is provided in a two-fold rotationally symmetrical shape. The accommodating portion 200 is below the respective fall prevention portions 199. The circumferential direction reverse rotation direction side 200a and the radial direction inner direction 200b of the accommodation portion 200 are opened, and the circumferential direction normal rotation direction side 200c is closed. Reference numeral 202 denotes a spiral sloped surface provided from the upper surface of each drop prevention portion 199 toward the accommodation portion 200 on the forward rotation direction side. Reference numeral 204 is a fitting groove for fitting the outer side portion of the receiving projection 185.

FIG. 23 is a plan view of the connecting portion 44 in which the inner shell portion 179 is fitted inside the outer shell portion 181, and FIG. 24 is a sectional view taken along line XXIV-XXIV in FIG. The connecting portion 44 opens upward, and the peripheral wall 180 of the inner shell portion 179 is fitted inside the bowl-shaped portion 195 of the outer shell portion 181. In addition, the receiving projection 185 is fitted to the circumferential normal rotation direction side 200c of the housing portion 200, and the outer side portion of the receiving projection 185 is fitted to 204. The receiving projection 185, the drop-out preventing portion 199, and the housing portion 200 constitute a holding portion. In this state, the distance between the upper surface of the inner shell portion 179 and the lower surface of the dropout prevention portion 199 is set to be longer than the vertical length of the protruding portion 177.

The handle 20 is pushed down to hold the operation lever 19 on the holding member 23, thereby raising the rotary drive force transmission portion 169, and the connecting portion 44 of the rotary pad 42 is positioned below the rotary driving force transmitting portion 169. When the driving force transmitting portion 169 is fitted from above, the fitting is performed with the connecting portion 44 and the center of the rotational driving force transmitting portion 169 and the axial direction aligned or close to each other, and the inching switch 39 is slightly moved. When the rotational driving force transmitting portion 169 is rotated with respect to the connecting portion 44 in the forward direction for a short time by pressing the connecting portion 44 for a short time, the two protruding portions 177 provided in a two-fold rotational symmetry form two The convex curved surface 175 is held by a holding portion including the receiving projection 185, the fall prevention portion 199, and the accommodating portion 200, which are provided in a rotationally symmetrical manner, and the convex curved surface 175 has a concave curved surface 18 as shown in FIG. Supported by 3. In this way, the rotary driving force transmitting portion 169 and the rotary pad 42 are connected. Of course, the rotation driving force transmission unit 169 can be connected even if it is continuously rotated in the forward direction.

The protrusion 177 is received from the opened circumferential direction reverse rotation direction side 200 a of the accommodation unit 200, the circumferential direction normal rotation direction side of the protrusion 177 is received by the receiving surface 187, and the upper side of the storage unit 200 is received. Since the drop-out prevention portion 199 is provided on the shaft, the rotation driving force transmission portion 169 rotates in the forward rotation direction (counterclockwise in FIG. 23) about the axis of the rotation driving force transmission portion 169 to transmit the rotation driving force. The connection between the portion 169 and the connecting portion 44 is maintained, and the rotary pad 42 is driven in the normal direction. The convex curved surface 175 and the concave curved surface 183 are rotationally symmetrical, and since the accommodating portion 200 accommodates the protruding portion 177 with a margin in the vertical direction, the connecting portion 44 and the rotation driving force transmitting portion 169 are included. Even when the axial directions of the two do not completely coincide with each other and the other is inclined in an arbitrary direction to some extent, the convex curved surface 175 can be supported by the concave curved surface 183, and the protrusion 177 is held by the holding portion to rotate. It does not affect the connection between the driving force transmission part 169 and the connection part 44 and the normal rotation drive of the rotary pad 42. Therefore, the connection can be easily performed, and it is highly adaptable to changes in the slope or unevenness of the floor surface.

Since the spiral inclined surface 202 is provided from the upper surface of each drop prevention portion 199 in the connecting portion 44 toward the accommodation portion 200 on the forward rotation direction side, the rotational driving force transmitting portion 169 is provided above the connecting portion 44. When the rotation driving force transmitting portion 169 is rotated in the forward rotation direction relative to the connecting portion 44 to connect the rotational driving force transmitting portion 169 and the connecting portion 44, the protrusion 177 has a spiral shape. It is guided to the accommodating portion 200 along the slope 202. Therefore, the connection can be performed more smoothly. By pushing down the handle 20 and holding the operation lever 19 by the holding member 23, the rotary drive force transmission portion 169 is lifted so that the rotary pad 42 is located above the floor surface, road surface, etc., and the inching switch 39 is turned on for a short time. When the rotational driving force transmitting portion 169 is rotated in the forward direction for a short time by pressing only, the deceleration of the rotational driving force transmitting portion 169 which is stopped causes an inertial force acting on the rotating pad 42 that has started to rotate. As a result, the two holding portions of the rotary pad 42 fall in the forward rotation direction from the two protrusions 177 of the rotary drive force transmitting portion 169, and the rotary pad 42 can be easily removed from the rotary drive force transmitting portion 169. it can.

It should be noted that the rotation driving force transmitting portion 169 can be rotated in the forward direction for a short time by using the ordinary switch 37, depending on the mode of the switch. In addition, the wheel 52 applies a downward load due to the weight 54 and the like to the rotary pad 42 at a substantially constant position with respect to the support frame 24, so that the rotation axis of the rotary pad 42 is rotated. When the inching switch 39 is pressed for a short time while the tilting axis is maintained slightly inclined with respect to the rotation axis, and the rotation driving force transmitting section 169 is rotated in the forward direction for a short time, the rotation axis shifts. It becomes easier to drop the holder from the protrusion 177 and to remove the rotary pad 42 from the rotary drive force transmitter 169.

The rotary pad 42 is rotatably supported by a hollow fixed shaft 165 fixed to the support frame 24 via ball bearings 171 and 173 (and a rotary driving force transmission part 169 and a connection part 44). Therefore, the drive motor 38, the drive belt 41, the driven pulley 40, and the like drive the support frame 24 to rotate. Then, while rotating the rotation pad 42, the detergent from the detergent tank 151 is supplied with the detergent from the detergent tank 151 through the upper opening of the hollow fixed shaft 165 which is kept relatively stationary with respect to the support frame 24. It can be supplied via 167, and can be sprayed from the lower opening 165a onto the floor surface of the central portion of the rotary pad 42 and washed by the rotary pad 42. Since the periphery of the detergent introducing pipe 167 for introducing the detergent into the hollow fixed shaft 165 is surrounded by the mortar-shaped recess 163, the detergent leaking from the detergent introducing pipe 167 or its peripheral portion is stored in the mortar-shaped recess 163. As a result, it is possible to more reliably prevent the detergent from being inadvertently spattered and contaminating the peripheral portion other than the device, and adversely affecting the mechanism of the device.

Needless to say, other than the above-described embodiments, various applications and modifications can be made without departing from the gist of the present invention.
