The overflow path 30 is a hose of a predetermined length. In the overflow passage 30, the inlet 30A constituting one end thereof penetrates the base 20 from the lower side Z2, and is connected to a predetermined position closer to the upper side Z1 than the bottom wall 35 on the circumferential wall 34 of the water tank 21, from the radially outer side R1 and The inside of the water tank 21 is connected (refer to FIG. 7). In the overflow path 30, the outlet 30B constituting the other end thereof is connected to a portion closer to the outlet 28B side than the unit side drain valve 29 in the unit side drain path 28.

The portion other than the front cover 24 of the extraction portion 4 as described above is inserted into the opening portion 10 of the main body portion 3 from the front side X1, and is housed in the internal space 3A of the main body portion 3. The front cover 24 closes the opening 10 from the front side X1, and the position of the extraction portion 4 when the portion other than the front cover 24 is completely housed in the internal space 3A in the extraction portion 4 is referred to as a storage position (see FIG. 1).

In the drawing portion 4 of the storage position, the left and right slide rails 31 are in a state in which the main body portion 3 is fitted between the upper end portion 12A and the lower end portion 12B (see FIG. 2) of the guide rail 12 on the same side in the left-right direction Y. In the extraction portion 4 of the storage position, the hose protector 32 in a state in which the intermediate portion 28C of the unit side drain passage 28 is covered from the lower side Z2 is in the pressing member 13 (see FIG. 2) of the main body portion 3; The state of the lower side Z2. Therefore, the intermediate portion 28C of the unit side drain path 28 is housed between the hose protector 32 and the pressing member 13.

Further, in the drawing portion 4 of the storage position, the inlet 38A (see FIG. 3) of the water supply pipe 38 is located directly below the water supply joint 14 (see FIG. 2) of the main body portion 3, and the bottom wall of the water supply joint 14 from the lower side Z2. All of the through holes 14C on the 14B are opposed to each other. Thereby, the water supply hose 15, the internal space of the water supply joint 14, and the internal space of the water supply pipe 38 are connected, and the collection of these constitutes the unit side water supply path 52 of the shoe washing unit 1 (see also FIG. 7).

When the user grasps the handle 40 of the front cover 24 of the drawing portion 4 of the storage position to the front side X1, each of the slide rails 31 is guided to the front-rear direction X by the guide rails 12, and the casters 41 of the drawing portion 4 are in the main body. The upper surface of the lower wall 6 of the portion 3 rolls, and the extraction portion 4 is drawn toward the front side X1. When the extraction portion 4 slides until the lid 23 is located closer to the front side X1 than the opening portion 10 of the main body portion 3, the extraction of the extraction portion 4 toward the front side X1 is stopped, and the position of the extraction portion 4 at this time is set to be extracted. Position (refer to FIG. 8 mentioned later).

In the extraction portion 4 at the extraction position, the inlet 38A of the water supply pipe 38 is displaced from the water supply joint 14 of the main body portion 3 toward the front side X1, and is not opposed to the through hole 14C of the water supply joint 14 from the lower side Z2, so the unit side The water supply path 52 is in a state of being cut in the middle.

As the extraction unit 4 is extracted from the storage position to the extraction position, the midway portion 28C that is in the bent state is extended linearly in the unit side drainage path 28 . However, the length of the unit-side drainage path 28 has a margin to some extent that the unit-side drainage path 28 does not become tight when the extraction portion 4 reaches the extraction position.

While the extraction portion 4 is being withdrawn from the storage position to the extraction position, the hose protector 32 of the extraction portion 4 is exposed from the pressing member 13 of the main body portion 3 toward the front side X1, but the hose protector 32 is continued from the lower side Z2. The state of the unit side drain path 28 is covered. Therefore, it is possible to prevent the unit side drain path 28 from being entangled with the main body portion 3 during the movement of the drawing portion 4, or the unit side drain path 28 is drooping to come into contact with the floor.

When the user mainly grasps the handle 40 of the drawing portion 4 at the drawing position and pushes it to the rear side X2, the drawing portion 4 can be returned from the drawing position to the storage position. When the extraction unit 4 returns to the storage position, the unit-side water supply path 52 is eliminated in the middle, and the entire unit-side water supply path 52 is in the ON state.

Fig. 7 is a schematic longitudinal sectional right side view of the washing machine 2 to which the shoe washing unit 1 is attached. Next, an outline of the washing machine 2 will be described with reference to Fig. 7 .

The washing machine 2 is, for example, a drum type washing machine, and includes a casing 60, a housing groove 61, a water supply path 62, a drain path 63, and a main body side drive unit 64.

The housing 60 is formed in a box shape. The lower side region 60B which constitutes a substantially lower half portion on the front surface 60A of the casing 60 extends in the up-and-down direction Z, and the upper side region 60C which constitutes the substantially upper portion on the front surface 60A goes further toward the upper side Z. The side X2 extends in such a manner as to be inclined with respect to the vertical direction Z. The lower side region 60B is formed with an insertion port 75 inserted into the shoe washing unit 1 attached to the washing machine 2. The upper side region 60C is formed with an opening 65 that communicates inside and outside the casing 60. The upper side region 60C is provided with a door opening the opening 65 66.

The accommodating groove 61 is disposed in a region of the upper half of the casing 60 that faces the substantially upper half of the opening from the rear side X2. Therefore, there is a space 60D in the inner space of the casing 60, the space 60D having a size that is placed at the lower side Z2 of the accommodation groove 61.

The accommodating groove 61 includes a bottomed cylindrical outer groove 67 and a bottomed cylindrical drum 68 that is coaxially housed in the outer groove 67 and that is smaller than the outer groove 67.

In the outer groove 67, the end portion of the front side X1 is provided with an inlet and outlet 67A for exposing the inner space of the outer groove 67 to the front side X1, and the end portion of the rear side X2 is provided with a disk-shaped bottom wall constituting the bottom of the outer groove 67. 67B. The doorway 67A faces the opening 65 of the casing 60 from the rear side X2. Since the entrance and exit 67A is disposed at a position shifted from the upper side Z1 of the bottom wall 67B, the outer groove 67 is disposed obliquely with respect to the horizontal direction H. Water such as tap water, bath water, and a liquid in which a lotion is dissolved is stored in the outer tank 67.

In the drum 68, an end portion 68A for exposing the inner space of the drum 68 to the front side X1 is provided at the end portion of the front side X1, and a disc-shaped bottom wall 68B constituting the bottom of the drum 68 is provided at the end portion of the rear side X2. The doorway 68A faces the outlet port 67A and the opening 65 of the casing 60 from the rear side X2, respectively. Since the inlet and outlet 68A is disposed at a position shifted from the upper side Z1 of the bottom wall 68B, the drum 68 is disposed obliquely with respect to the horizontal direction H as the outer groove 67. The drum 68 is formed with a plurality of through holes (not shown) through which water in the outer tank 67 can pass between the outer tank 67 and the drum 68. Therefore, the water level in the outer tank 67 coincides with the water level in the drum 68.

When the user opens the door 66, the opening 65 of the casing 60, the entrance and exit 67A of the outer tub 67, and the entrance and exit 68A of the drum 68 are simultaneously opened, and are exposed to the front side X1 of the washing machine 2. The user can take the laundry 69 out of the inlet 68A into the drum 68. When the user closes the door 66, as shown in Fig. 7, the opening 65, the inlet and outlet 67A, and the inlet and outlet 68A are closed together.

The water supply path 62 is a pipe having one end connected to a tap of tap water as a water supply device, and the other end 62A of the water supply path 62 is connected to the outer tank 67 from the upper side Z1 in the casing 60. The water supply path 62 supplies tap water flowing from the faucet into the outer tank 67 as indicated by the hollow arrow and the dotted arrow. In the middle of the water supply path 62, a main body side water supply valve 70 that opens to start or stop the water supply is provided.

The drain path 63 is a hose disposed in the casing 60, and has an inlet 63A that is connected to the lowermost portion of the outer tank 67 as one end thereof, and an outlet 63B that is the other end of the side opposite to the inlet 63A. The outlet 63B is connected to a drainage device other than the washing machine such as a drain pipe (not shown) of the building. The water in the outer tank 67 is discharged from the drain path 63 to the outside of the washing machine as indicated by a hollow black arrow. In the middle of the drainage path 63 A main body side drain valve 71 that opens to start or stop the drain is provided.

The main body side drive portion 64 is an electric motor provided on the rear side X2 of the bottom wall 67B of the outer tub 67. The main body side drive unit 64 includes an output shaft 64A that rotates to output a driving force. The output shaft 64A penetrates the center portion of the bottom wall 67B of the outer groove 67 from the rear side X2, and connects the center portion of the bottom wall 68B of the drum 68 from the rear side X2. When the main body side driving portion 64 is driven, the rotation of the output shaft 64A is transmitted to the drum 68, and the drum 68 is rotated about the output shaft 64A. The washing and cleaning of the laundry 69 accommodated in the drum 68 is performed by the rotation of the drum 68. Further, in the drum 68, a washing blade 69 (not shown) of the laundry 69 in the agitating drum 68 may be provided to be rotated by the rotation of the receiving output shaft 64A.

The washing machine 2 includes a wire 72 for supplying electric power from an external power source (not shown) to an electric component in the washing machine 2 including the main body side drive unit 64. In FIG. 7, the wiring 72 is shown by a one-dot chain line in the casing 60, and the electric wire 72A which has the plug 73 connected to the top of the casing 60 is shown in figure. When the user inserts the plug 73 into a socket (not shown), the wiring 72 is connected to the power source to supply power to the electrical components in the washing machine 2.

Such a washing machine 2 is equipped with a shoe washing unit 1. The shoe washing unit 1 is inserted into the insertion port 75 formed in the lower side region 60B of the front surface 60A of the casing 60 of the washing machine 2 from the front side X1, and is disposed in the space 60D on the lower side of the accommodation groove 61 in the internal space of the casing 60. Therefore, since the shoe washing unit 1 is built in the washing machine 2, the installation place of the washing machine 2 can be shared for the setting of the shoe washing unit 1, and the shoe washing unit 1 can be disposed not to be exposed from the washing machine 2, so that the shoe washing unit can be eliminated 1 set the location related issues. Further, the casing 60 is provided with a rectangular parallelepiped frame (not shown) for supporting the shoe washing unit 1 disposed in the space 60D. In addition, in FIG. 7, for convenience of description, the base 20 of the shoe washing unit 1 and the water tank 21 are shown integrally, and the illustration of the gear case 55 etc. mentioned above is abbreviate|omitted.

In the shoe washing unit 1 attached to the washing machine 2, in the water supply hose 15 constituting the unit side water supply path 52, the other end portion 15B on the opposite side to the one end portion 15A is connected via a connecting member (not shown). The water supply path 62 of the washing machine 2 is coupled. The other end portion 15B is connected to a portion of the water supply path 62 that is closer to the upstream side of the faucet than the main body side water supply valve 70. Further, in the shoe washing unit 1, the outlet 28B of the unit side drain path 28 penetrates, for example, the rear wall 9 of the main body portion 3, and the main body side drain valve 71 and the outlet of the drain path 63 of the washing machine 2 via a connecting member (not shown). The middle part of the connection between 63B is connected.

Further, the shoe washing unit 1 includes a unit side wiring 80 for supplying electric power from an external power source to an electric component (not shown) in the shoe washing unit 1 including the unit side driving unit 27. In Figure 7, the unit side wiring 80 is indicated by a two-dot chain line. In the shoe washing unit 1 attached to the washing machine 2, the unit side wiring 80 is connected to the wiring 72 of the washing machine 2 via a connector (not shown). Therefore, as long as the user inserts the plug 73 of the washing machine 2 into the socket (not shown), the unit side wiring 80 can supply power from the wiring 72 connected to the power source to the electric components in the shoe washing unit 1. In addition, when the extraction unit 4 is moved from the storage position to the extraction position, the length of the portion is set such that the portion connected to the unit-side drive unit 27 on the side of the extraction unit 4 in the unit-side wiring 80 is not tight. It is determined to have a certain margin (see Figure 8).

In the shoe washing unit 1 of Fig. 7, the drawing portion 4 is located at the storage position, and the front cover 24 of the drawing portion 4 closes the opening portion 10 of the main body portion 3 from the front side X1, and is located along the casing 60 of the washing machine 2 from the front side X1. The state of the lower side region 60B of the front surface 60A. In the shoe washing unit 1 attached to the washing machine 2, the state in which the drawing unit 4 is moved to the drawing position is illustrated in Fig. 8 .

In the drawing portion 4 at the drawing position, the lid 23 is located on the front side X1 of the lower side region 60B of the front surface 60A of the washing machine 2. Therefore, as shown in FIG. 8, the lid 23 can be opened from the closed position to the open position toward the upper rear side, and the inlet and outlet 36 of the water tank 21 is exposed to the upper side Z1, and as indicated by the dotted arrow, from the upper side Z1 via the inlet and outlet 36. The shoe 77 is taken out and put into the water tank 21. In addition, although FIG. 8 illustrates the case where the pair of shoes 77 are accommodated in the water tank 21, the number of shoes 77 which can be accommodated can be arbitrarily changed according to the space in the water tank 21.

When the input shoe 77 is taken out into the water tank 21, the drawing portion 4 at the drawing position is pushed into the storage position of the rear side X2. When the extraction portion 4 at the extraction position is pushed, the lid 23 at the open position so far can be closed to a predetermined closed position, but the lid can be maintained at the open position. When the drawing portion 4 of the drawing position is pushed in while the lid 23 is maintained in the open position, the lower side region 60B of the front surface 60A of the washing machine 2 and the front end portion of the upper wall 5 of the main body portion 3 are from this period. Since the rear side X2 abuts against the lid 23, the lid 23 is rotated about the hinge 39 and is arbitrarily closed to the closed position.

Further, when the extraction portion 4 is at the storage position, the lid 23 is in a state of being pressed by the upper wall 5 of the main body portion 3 from the upper side Z1, and therefore, the lid 23 is not arbitrarily opened and maintained at the closed position (see Fig. 7). Further, since the lid 23 located at the closed position and the periphery of the inlet and outlet 36 of the water tank 21 are sealed by a gasket (not shown), the water in the water tank 21 does not leak from the inlet and outlet 36 while the lid 23 is in the closed position.

Referring to Fig. 9, the shoe washing unit 1 includes a control unit 81 composed of, for example, a memory such as a CPU, a ROM, and a RAM.

The unit side water supply valve 16, the unit side drain valve 29, and the unit side drive unit 27 described above are respectively controlled The part 81 is electrically connected. The control unit 81 controls the opening of each of the unit side water supply valve 16 and the unit side drain valve 29 or the operation of the control unit side drive unit 27.

The control unit 81 is attached to the extraction unit 4 as a sliding side (see FIG. 5). The unit side water supply valve 16 and the control unit 81 provided on the main body portion 3 as the fixed side are connected to a signal line (not shown) of the unit side water supply valve 16 by a control signal sent from the control unit 81. The length of the signal line is set to have a certain margin so that the signal line does not become tight when the extraction portion 4 is moved from the storage position to the extraction position.

The shoe washing unit 1 further includes an operation unit 82 electrically connected to the control unit 81, a position sensor 83, a water level sensor 84, and a timer 85.

The operation unit 82 is operated by the user to start the operation or stop of the shoe washing unit 1 or to set the operating conditions of the shoe washing unit 1. The operation unit 82 is provided on the front surface of the front cover 24 of the extraction unit 4 (see FIG. 1). Further, the operation unit 82 may be an operation panel for the washing machine 2 provided on the front surface 60A of the casing 60 of the washing machine 2. In this case, the control unit 81 and the operation unit 82 are electrically connected via a predetermined interface. In either case, the operation content of the operation unit 82 issued by the user is input to the control unit 81. Further, in the operation unit 82, the operation state and the operation condition of the shoe washing unit 1 may be displayed as visually readable or provided with a buzzer.

The position sensor 83 is a sensor that detects whether the extraction unit 4 is located at the storage position or the extraction position, and the detection result of the position sensor 83 is input to the control unit 81. The water level sensor 84 is a sensor that detects the water level of the water tank 21, and the detection result of the water level sensor 84 is input to the control unit 81. The timer 85 is a time measuring unit, and the measurement content generated by the timer is input to the control unit 81.

Next, the flow of the washing operation of the shoe 77 performed in the shoe washing unit 1 will be specifically described with reference to the flowchart of Fig. 10 .

When the extraction unit 4 is located at the storage position (step S1: YES), when the operation of the operation unit 82 by the user instructs the start of the cleaning operation (step S2: YES), the control unit 81 starts water supply to the water tank 21 (step S3). Further, a lock mechanism (not shown) that locks the position of the extraction portion 4 may be provided in the shoe washing unit 1, and the extraction portion 4 is first locked at the storage position before the start of water supply.

Specifically, the control unit 81 opens the unit-side water supply valve 16 in a state where the unit-side drain valve 29 is closed, as the water supply in the step S3 is started. Thereby, the water from the faucet flows into the other end portion 15B of the water supply hose 15 from the water supply path 62 of the washing machine 2, and is guided to the water tank 21 through the unit side water supply path 52. In the unit-side water supply path 52, water flows into the water supply joint 14 from the one end portion 15A of the water supply hose 15, and after falling from the respective through holes 14C of the bottom wall 14B of the water supply joint 14 to the inlet 38A of the water supply pipe 38, The inside of the water tank 21 is injected from the outlet 38B of the water supply pipe 38 (refer to the solid arrow in Fig. 7). The lotion is previously placed in the water tank 21, and the water stored in the water tank 21 is the washing water in which the lotion is dissolved.

When it is detected by the water level sensor 84 that the water supply to the water tank 21 has been completed to a predetermined water level, and the water tank 21 is filled with water (step SS4: YES), the control unit 81 closes the unit side water supply valve 16 to stop the water supply, and drives the unit side drive unit. 27. The start timer 85 starts the time measurement (step S5). In addition, even if the water level in the water tank 21 rises to the above-described predetermined water level, water of a predetermined water level or more overflows from the inlet 30A of the overflow water path 30 into the overflow water path 30, and drains through the unit side drainage path 28 and the washing machine 2 The path 63 is discharged to the outside of the washing machine (refer to the arrow of the alternate long and short dash line in Fig. 7).

When the unit side drive unit 27 is driven in step S5, the rotating body 25 in the water tank 21 is rotated. Thereby, the shoe 77 provided between the circumferential wall 34 and the protruding portion 43 of the rotating body 25 in the water tank 21 is cleaned by being brushed by the first brush 46 and the second brush 47 of the rotating rotating body 25. In other words, the stain can be removed from the shoe 77 by the first brush 46 and the second brush 47.

Further, although the shoe 77 is changed in posture or moved by the brushing here, at this time, the movement of the shoe 77 in the water tank 21 is guided by the third brush 48 of the circumferential wall 34 to be, for example, a rotation-down rotation. Therefore, since the posture of the shoe 77 in the cleaning can be changed by the guidance by the third brush 48, the first brush 46 and the second brush 47 can brush off the stain throughout the shoe 77 in a wide range. Since the shoe 77 is not only washed by the first brush 46 and the second brush 47 but also by the third brush 48 by brushing, the shoe 77 can be washed more efficiently.

Here, as described above, since the third brush 48 is inclined and extended in the horizontal direction H, it is easy to apply force to the shoe 77 as compared with the case of extending in the horizontal direction H, so that it can be efficiently brushed off from the shoe 77. Stains (see Figure 5).

However, since the third brush 48 which is inclined and extended in the horizontal direction H is compared with the case where it extends in the vertical direction (up and down direction Z), the resistance of the shoe 77 from the third brush 48 can be made small, so that the sink can be prevented. The smooth movement of the shoe 77 in 21 is hindered by the third brush 48 and the damage of the shoe 77 caused by the third brush 48. Further, as compared with the case where the third brush 48 extends in the vertical direction, the size of the third brush 48 in the vertical direction can be suppressed, and the size of the water tank 21 and the shoe washing unit 1 in the vertical direction can be suppressed from being reduced. The water in the water tank 21 can be prevented from jumping in the longitudinal direction from the third brush 48.

Moreover, by extending the third brush 48 in a spiral shape, the structure in which the third brush 48 is inclined and extended in the horizontal direction H can be easily realized.

In step S5, after a predetermined cleaning time has elapsed after the timer 85 is started (step S6: YES), The control unit 81 stops the unit side drive unit 27, opens the unit side drain valve 29 to start draining of the water tank 21, and starts the timer 85 to start the new timer (step S7). Thereby, the water in the water tank 21 flows into the unit side drain path 28 from the inlet 28A of the unit side drain path 28, is guided to the drain path 63 of the washing machine 2 through the unit side drain path 28, and is discharged to the outside of the washing machine via the drain path 63 (refer to The arrow of the two-dot chain line in Fig. 7).

The stains such as mud and stones adhering to the shoe 77 are washed by the brushes 46 to 48 and the washing water is removed from the shoe 77, and most of the stains are discharged together with the water to the outside of the washing machine. Although it is conceivable that a part of the stain is not discharged outside the washing machine and remains on the bottom wall 35 of the water tank 21, the stain may be widely distributed between the peripheral portion 35B of the bottom wall 35 and the outer periphery 42A of the bottom portion 42 of the rotating body 25. The secured gap 44 is marginally accepted (see Figure 7). Therefore, it is possible to prevent the stain from being deposited between the peripheral portion 35B of the bottom wall 35 and the bottom portion 42 of the rotating body 25, thereby preventing the smooth rotation of the rotating body 25.

In step S7, after a predetermined drain time has elapsed after the timer 85 is started (step S8: YES), the control unit 81 closes the unit side drain valve 29 to stop draining (step S9). At this time, the inside of the water tank 21 is in a state of being substantially drained.

Next, the control unit 81 starts the same water supply as the step S3 for the shoe 77 in the rinsing water tank 21 (step S10). When the water tank 21 is full of water (step S11: YES), the control unit 81 closes the unit-side water supply valve 16 to stop the water supply, and drives the unit-side driving unit 27 to start the timer 85 to start the new timer (step S12).

In step S12, the rotary body 25 is rotated together with the first brush 46 and the second brush 47 in the water tank 21 by the drive unit side drive unit 27. Thereby, the shoe 77 in the water tank 21 is rinsed by the first brush 46 and the second brush 47 as it is immersed in water, or is brushed by the third brush 48.

In step S12, after a predetermined rinsing time has elapsed after the timer 85 is started (step S13: YES), the control unit 81 stops the unit-side driving unit 27, opens the unit-side drain valve 29, starts draining of the water tank 21, and starts the timer 85. The newly set timing is started (step S14).

In step S14, after a predetermined drain time has elapsed after the start of the timer 85 (step S15: YES), the control unit 81 drives the unit side drive unit 27 to start the timer 85 while continuing to open the unit side drain valve 29. The newly set timing is started (step S16). By the driving of the unit-side driving portion 27 here, the rotating body 25 rotates together with the first brush 46 and the second brush 47 in the water tank 21. Thereby, the shoe 77 in the water tank 21 is rotated together with the first brush 46 and the second brush 47 to be dehydrated. Further, at this time, the first brush 46 and the second brush 47 themselves are also dehydrated.

In step S16, after a predetermined dehydration time has elapsed after the timer 85 is started (step S17: YES), The control unit 81 stops the unit-side driving unit 27, opens the unit-side drain valve 29, and discharges the drain of the water tank 21 for a predetermined period of time, and displays the meaning of the cleaning of the shoe 77 by displaying it on the operation unit 82, a buzzer or the like (step S18).

As described above, the shoe washing unit 1 attached to the washing machine 2 independently includes the water tank 21 that stores the shoe 77 and stores the water, and since the shoe 77 can be washed in the water tank 21, the shoe 77 is washed in the storage groove 61 of the washing machine 2. It is healthier than it is.

The shoe washing unit 1 can guide the water from the water supply path 62 of the washing machine 2 to the water tank 21 through the unit side water supply path 52, and can guide the water of the water tank 21 to the drainage path 63 of the washing machine 2 through the unit side drainage path 28. Therefore, since the water supply and drainage apparatus of the washing machine 2 can be shared for the water supply and drainage in the shoe washing unit 1, the additional water supply and drainage equipment which is not newly provided as the shoe washing unit 1 can be completed.

In the shoe washing unit 1, when the rotating body 25 provided in the water tank 21 is rotated by the unit side driving portion 27, the first brush 46, the second brush, and the third brush 48 provided in the rotating body 25 are brushed. Stubborn stains such as mud can also be removed from the shoe 77 in the water tank 21, and the shoe 77 can be efficiently cleaned.

In the shoe washing unit 1, since the unit side driving portion 27 can be supplied from the wiring 72 of the washing machine 2 through the unit side wiring 80, the power supply to the washing machine 2 is shared by the power supply to the unit side driving portion 27.

Thus, the shoe washing unit 1 and the washing machine 2 to which the shoe washing unit 1 is attached can eliminate the problems associated with the setting of the shoe washing unit 1 in the installation place, the water supply and drainage device, the power source, and the sanitary side, and efficiently clean the shoe 77.
