  The shoe cleaning unit 1 also includes unit side wiring 80 for supplying electric power from an external power source (not shown) to the electrical components in the shoe cleaning unit 1 including the unit side drive unit 27. In FIG. 7, the unit side wiring 80 is illustrated 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, when the user inserts the plug 73 of the washing machine 2 into an outlet (not shown), the unit-side wiring 80 can supply power from the wiring 72 connected to the power source to the electrical components in the shoe cleaning unit 1. become. Note that the length of this portion is such that the portion connected to the unit side drive portion 27 on the drawer portion 4 side in the unit side wiring 80 does not stretch when the drawer portion 4 moves from the housing position to the drawer position. It is set with some margin (see FIG. 8).

  In the shoe washing unit 1 of FIG. 7, the drawer 4 is in the storage position, and the front cover 24 of the drawer 4 closes the opening 10 of the main body 3 from the front side X1 and also the front surface of the housing 60 of the washing machine 2. The lower region 60B of 60A is in a state along the front side X1. FIG. 8 shows a state in which the drawer unit 4 is moved to the drawer position in the shoe washing unit 1 attached to the washing machine 2.

  In the drawer portion 4 at the drawer position, the lid 23 is located on the front side X1 with respect to the lower region 60B of the front surface 60A of the washing machine 2. Therefore, as shown in FIG. 8, the lid 23 is opened from the closed position to the open position with the rear upper side exposed to expose the inlet / outlet port 36 of the water tank 21 to the upper side Z1, and as indicated by the dotted arrow, the upper side Z1 is passed through the inlet / outlet port 36. The shoes 77 can be taken in and out of the water tank 21. In FIG. 8, a state in which a pair of shoes 77 is stored in the water tank 21 is illustrated, but the number of shoes 77 that can be stored can be arbitrarily changed according to the space in the water tank 21.

  When the taking-in / out of the shoe 77 into / from the water tank 21 is completed, the drawer portion 4 at the drawer position is pushed into the storage position of the rear side X2. When pushing in the drawer portion 4 at the drawer position, the lid 23 that has been in the open position so far may be closed in the closed position in advance, but may remain in the open position. When the drawer portion 4 in the drawer position is pushed in with the lid 23 in the open position, the lower 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 3 are placed on the lid 23 on the rear side X2. Therefore, the lid 23 rotates about the hinge 39 and closes to the closed position without permission.

  When the drawer portion 4 is in the storage position, the lid 23 is pressed from the upper side Z1 by the upper wall 5 of the main body portion 3, so that the lid 23 is maintained in the closed position without being opened without permission (see FIG. 7). Further, since the gap between the lid 23 in the closed position and the periphery of the inlet / outlet 36 of the water tank 21 is sealed by a packing (not shown), the water in the water tank 21 leaks out of the inlet / outlet 36 with the lid 23 in the closed position. There is nothing.

FIG. 9 is a block diagram showing an electrical configuration of the shoe cleaning unit 1.
Referring to FIG. 9, shoe cleaning unit 1 includes a control unit 81 configured with, for example, a CPU and a memory such as a ROM or a RAM.
The control unit 81 is electrically connected to each of the unit-side water supply valve 16, the unit-side drain valve 29, and the unit-side drive unit 27 described above. The controller 81 controls the opening and closing of the unit-side water supply valve 16 and the unit-side drain valve 29, and controls the operation of the unit-side drive unit 27.

  The control part 81 is attached to the drawer part 4 which is a slide side (refer FIG. 5). The unit-side water supply valve 16 and the control unit 81 provided in the main body 3 that is the fixed side are connected by a signal line (not shown) that transmits a control signal from the control unit 81 to the unit-side water supply valve 16. The length of the signal line is set with a certain margin so that the signal line does not become tight when the drawing portion 4 moves from the housing position to the drawing position.

  Shoe cleaning unit 1 further includes an operation unit 82, a position sensor 83, a water level sensor 84, and a timer 85 that are electrically connected to control unit 81.

  The operation unit 82 is operated by the user in order to start or stop the operation of the shoe cleaning unit 1 or to set the operation conditions of the shoe cleaning unit 1. The operation part 82 is provided on the front surface of the front cover 24 of the drawer part 4 (see FIG. 1). Alternatively, the operation unit 82 may be an operation panel for the washing machine 2 provided on the front surface 60 </ b> A of the casing 60 of the washing machine 2. In that case, the control unit 81 and the operation unit 82 are electrically connected via a predetermined interface. In any case, the operation content of the operation unit 82 by the user is input to the control unit 81. In addition, the operation part 82 may be provided with a function of displaying a driving condition and driving conditions of the shoe washing unit 1 so as to be visible or sounding a buzzer.

  The position sensor 83 is a sensor that detects whether the drawer 4 is in the storage position or the drawer position, and the detection result of the position sensor 83 is input to the controller 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 measures time, and the content measured by the timer is input to the control unit 81.

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

  When the drawer unit 4 is in the storage position (YES in step S1) and the start of the cleaning operation is instructed by the operation of the operation unit 82 by the user (YES in step S2), the control unit 81 supplies water to the water tank 21. Is started (step S3). Note that a lock mechanism (not shown) for locking the position of the drawer 4 may be provided in the shoe cleaning unit 1 and the drawer 4 may be locked at the storage position prior to the start of water supply.

  Specifically, as the water supply start in step S <b> 3, the control unit 81 opens the unit-side water supply valve 16 with the unit-side drain valve 29 closed. Thereby, the water from the faucet flows from the water supply path 62 of the washing machine 2 into the other end portion 15B of the water supply hose 15 and is guided to the water tank 21 by the unit side water supply path 52. In the unit-side water supply channel 52, water flows into the water supply joint 14 from one end 15 </ b> A of the water supply hose 15, falls from each through hole 14 </ b> C of the bottom wall 14 </ b> B of the water supply joint 14 to the inlet 38 </ b> A of the water supply duct 38, It is poured into the water tank 21 from the outlet 38B of the duct 38 (see the solid line arrow in FIG. 7). A detergent is put in the water tank 21 in advance, and the water stored in the water tank 21 becomes washing water in which the detergent is dissolved.

  When the water level sensor 84 detects that water has been supplied to the predetermined water level in the water tank 21 and the water tank 21 is full (YES in step SS4), the control unit 81 closes the unit-side water supply valve 16 and supplies water. Is stopped, the unit side drive unit 27 is driven, the timer 85 is started, and time measurement is started (step S5). Incidentally, even if the water level in the water tank 21 exceeds the above-mentioned predetermined water level, the water above the predetermined water level overflows into the overflow channel 30 from the inlet 30A of the overflow channel 30, and the unit side drainage channel 28 and the washing machine 2 It is discharged out of the machine through the drainage channel 63 (refer to the one-dot chain line arrow in FIG. 7).

  When the unit side drive unit 27 is driven in step S <b> 5, the rotating body 25 rotates in the water tank 21. Thereby, the shoe 77 set between the circumferential wall 34 and the protrusion 43 of the rotating body 25 in the water tank 21 is brushed by the first brush 46 and the second brush 47 of the rotating rotating body 25. It is washed by. That is, the first brush 46 and the second brush 47 can scrape dirt from the shoe 77.

  Further, the shoe 77 tries to change its posture or move by brushing here. At this time, the third brush 48 of the circumferential wall 34 causes the movement of the shoe 77 in the aquarium 21 to be, for example, a cone. It is guided so that it may become a shape rotation. Therefore, since the posture of the shoe 77 being washed can be changed by the guidance by the third brush 48, the first brush 46 and the second brush 47 scrape dirt over a wide range of the shoe 77. Can do. Since the shoe 77 is cleaned not only by the first brush 46 and the second brush 47 but also by the third brush 48 by brushing, the shoe 77 can be cleaned more effectively.

  Here, as described above, since the third brush 48 extends while being inclined in the horizontal direction H, the third brush 48 is more easily caught by the shoe 77 than in the case of extending along the horizontal direction H. It can be effectively scraped off (see FIG. 5).

  However, the third brush 48 that extends while being inclined in the horizontal direction H can reduce the resistance that the shoe 77 receives from the third brush 48 as compared with the case where the third brush 48 extends along the vertical direction (vertical direction Z). It is possible to prevent the smooth movement of the shoe 77 in the area 21 from being inhibited by the third brush 48 and to prevent the shoe 77 from being damaged by the third brush 48. Moreover, compared with the case where the 3rd brush 48 is extended along a perpendicular direction, the dimension of the 3rd brush 48 in a perpendicular direction, and also the dimension of the water tank 21 and the shoe washing unit 1 in a perpendicular direction can be restrained small. In addition, the water in the water tank 21 can be prevented from splashing vertically from the third brush 48.

  Then, by making the third brush 48 extend spirally, a configuration in which the third brush 48 extends while being inclined in the horizontal direction H can be easily realized.

  When a predetermined cleaning time has elapsed after the timer 85 is started in step S5 (YES in step S6), the control unit 81 stops the unit-side drive unit 27, opens the unit-side drain valve 29, and drains the water tank 21. Is started and the timer 85 is activated to start a new time measurement (step S7). Thereby, the water in the water tank 21 flows into the unit side drainage channel 28 from the inlet 28 </ b> A of the unit side drainage channel 28, and is led to the drainage channel 63 of the washing machine 2 by the unit side drainage channel 28. It is discharged out of the machine (see the two-dot chain arrow in FIG. 7).

  Dirt such as mud and stone adhering to the shoe 77 is removed from the shoe 77 by brushing by the brushes 46 to 48 and the washing water washing effect, and most of the dirt is discharged out of the machine together with water. It is conceivable that some dirt remains on the bottom wall 35 of the water tank 21 without being discharged out of the machine. This dirt is caused by the peripheral edge 35B of the bottom wall 35 and the outer peripheral edge 42A of the bottom 42 of the rotating body 25. Is received with a margin in the gap 44 that is relatively wide (see FIG. 7). Therefore, it is possible to prevent the dirt from clogging between the peripheral edge portion 35B of the bottom wall 35 and the bottom portion 42 of the rotating body 25 and hindering the smooth rotation of the rotating body 25.

  When a predetermined drainage time has elapsed after the timer 85 is started in step S7 (YES in step S8), the control unit 81 closes the unit-side drain valve 29 and stops draining (step S9). At this time, the inside of the water tank 21 is almost drained.

  Next, the controller 81 starts water supply in the same manner as Step S3 in order to rinse the shoes 77 in the water tank 21 (Step S10). When the water tank 21 is full (YES in step S11), the control unit 81 closes the unit-side water supply valve 16 to stop water supply, drives the unit-side drive unit 27, starts the timer 85, and starts a new time. Measurement is started (step S12).

  By driving the unit side drive unit 27 in step S <b> 12, the rotating body 25 rotates with the first brush 46 and the second brush 47 in the water tank 21. Thereby, the shoes 77 in the water tank 21 are rinsed by being brushed by the first brush 46 and the second brush 47 or brushed by the third brush 48 while being immersed in water.

  When the predetermined rinsing time has elapsed after the timer 85 is started in step S12 (YES in step S13), the control unit 81 stops the unit side drive unit 27, opens the unit side drain valve 29, and drains the water tank 21. And start the timer 85 to start a new time measurement (step S14).

  When the predetermined drainage time has elapsed after the timer 85 is started in step S14 (YES in step S15), the control unit 81 continues to drive the unit side drain valve 29 while driving the unit side drain valve 29, The timer 85 is activated to start a new time measurement (step S16). By driving the unit-side drive unit 27 here, the rotating body 25 rotates with the first brush 46 and the second brush 47 in the water tank 21. As a result, the shoes 77 in the water tank 21 rotate with the first brush 46 and the second brush 47 and are dehydrated. At this time, the first brush 46 and the second brush 47 themselves are also dehydrated.

  When a predetermined dehydration time has elapsed after the timer 85 is started in step S16 (YES in step S17), the control unit 81 stops the unit side drive unit 27, opens the unit side drain valve 29, and drains the water tank 21. Is performed for a predetermined time, and a notification that the cleaning of the shoe 77 has ended is given by a display 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 houses the shoes 77 and includes the water tank 21 in which water is stored, and can wash the shoes 77 in the water tank 21. This is sanitary compared to the case where the shoe 77 is washed in the tank 61.
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 by the unit side water supply path 52, and the water of the water tank 21 can be drained by the unit side drainage path 28. 63. Therefore, since the water supply / drainage facility of the washing machine 2 can be shared for the water supply / drainage in the shoe cleaning unit 1, it is not necessary to newly install an additional water supply / drainage facility for the shoe cleaning unit 1.

In the shoe cleaning unit 1, when the rotating body 25 provided in the water tank 21 is rotated by the unit-side drive unit 27, the first brush 46, the second brush, and the third brush provided on the rotating body 25. By brushing with 48, persistent dirt such as mud is also removed from the shoes 77 in the water tank 21, and the shoes 77 can be effectively washed.
In the shoe cleaning unit 1, power can be supplied from the wiring 72 of the washing machine 2 to the unit-side drive unit 27 by the unit-side wiring 80, so that the power supply of the washing machine 2 is shared for power supply to the unit-side drive unit 27. it can.

  Thus, in the washing machine 2 to which the shoe washing unit 1 and the shoe washing unit 1 are attached, the problems relating to the installation of the shoe washing unit 1 such as the installation location, water supply / drainage facilities, power supply and hygiene are eliminated and the shoe 77 is effectively used.

Further, the main body 3 of the shoe washing unit 1 may be a part of the housing 60 of the washing machine 2.

Further, the shoe washing unit 1 is built in the housing 60 of the washing machine 2 so as to be disposed in the space 60D on the lower side Z2 of the drum 68. However, the shoe washing unit 1 is not limited to this layout and is mounted on the housing 60 from the upper side Z1. It may be attached to the washing machine 2 so as to be placed.
In the washing machine 2, the drum 68 is disposed so as to be inclined with respect to the horizontal direction H, but may be disposed along the horizontal direction H or may be disposed along the vertical direction Z.
