It should be noted that the water supply passage 24 may be branched from the water supply passage of the washing machine (not shown) disposed on the upper side Z1 of the shoe washing apparatus 1 and connected to the duct 22 without being directly connected to the valve plug (not shown). . A water supply valve 39 (see FIG. 5A) including a solenoid valve or the like is attached to the middle of the water supply passage 24. It should be noted that the water supply passage 24 and the drain passage 37 are set to be somewhat longer to some extent based on the fact that the main body 3 can slide.

The main body 3 is provided with a control unit 40 (see Fig. 1) composed of a microcomputer or the like. The control unit 40 is electrically connected to the operation unit 4C, the heater 18, the blower unit 23, the pump 29, and the water supply valve 39 via wires (not shown). Therefore, the control unit 40 can accept the operation of the operation unit 4C by the user or control the operation of the heater 18, the blower unit 23, and the pump 29, and the opening and closing of the water supply valve 39.

Next, the washing operation of the shoe S by the shoe washing apparatus 1 will be described. The washing operation includes: a washing process of washing the shoe S by the washing liquid; a rinsing process of rinsing the shoe S by the washing liquid after the washing process; and a de-liquidizing process of removing moisture from the shoe S after the rinsing process. It should be noted that the cleaning liquid in the cleaning process is tap water in which the detergent is dissolved, and the cleaning liquid in the rinsing process is tap water containing no detergent component. It should be noted that bath water can also be used instead of tap water during the cleaning process.

Before the start of the washing operation, the user pulls the main body 3 of the shoe washing apparatus 1 to the pull-out position (not shown) to open the input and take-out port 13 of the washing tub 5, and stores a pair of shoes S from the input and take-out port 13 to the storage room. 11 upper space 11A. At this time, the user inserts the distal end portion 16B of each holding portion 16 into the shoe opening SH of the shoe S from the lower side Z2, and then inserts the internal space SN of the shoe S toward the toe ST side. Thereby, in the upper space 11A, the pair of shoes S are arranged in the left-right direction X, and the shoes S are respectively held by the holding portion 16 in a vertically inverted posture in the front-rear direction Y. The shoe S in the reverse posture is in a state in which the toe ST faces the front side Y1, the sole SZ faces the upper side Z1, and the upper portion SU and the shoe opening SH covering the instep face toward the lower side Z2. Further, when the user stores the shoe S in the storage chamber 11, the detergent is put into the storage chamber 11. Thereafter, the user returns the main body 3 to the storage position shown in FIGS. 2 to 4. Thereby, preparation for the washing operation is completed.

In the shoe washing apparatus 1 that completes the cleaning operation, in the storage chamber 11, the tower nozzle 30 of the rotary nozzle 26 is disposed between the pair of shoes S held in the reverse posture. The upper end portion 30A of the tower nozzle 30 is disposed to protrude toward the upper side Z1 of the sole SZ of these shoes S. Thereby, at least one of the plurality of injection ports 20A provided in the upper end portion 30A is disposed at a position higher than the sole SZ. The horizontal nozzles 31 of the rotary nozzle 26 are disposed at positions lower than the shoes S, and the ejection openings 20A of the horizontal nozzles 31 are disposed to face the upper portion SU and the shoe opening SH of the shoes S from the lower side Z2.

The pair of side nozzles 27 are disposed on both sides of a pair of shoes S in the storage chamber 11, that is, both outer sides in the left-right direction X. The side injection ports 20B of the side nozzles 27L are arranged sideways in the longitudinal direction of the shoe S substantially along the left side X1, and face the side portions SS of the left side X1 of the shoe S from the left side X1. The side ejection opening 20B of the side nozzle 27R is arranged in a state of being aligned along the longitudinal direction of the shoe S of the right side X2, and faces the side portion SS of the right side X2 of the shoe S from the right side X2. When viewed from the side, the side injection port 20B of the row L1 of the upper side Z1 of each of the side nozzles 27 is disposed to overlap with the portion of the side portion SS close to the sole SZ. In particular, the side injection port 20B of the front end in the column L1 is disposed to overlap with the portion of the side portion SS near the toe ST, and the side injection port 20B of the rear end in the column L1 is disposed to be close to the heel portion SK at the side portion SS. Partial overlap. When viewed from the side, the side injection port 20B of the row L2 of the lower side Z2 is disposed to overlap the portion of the side portion SS that is biased toward the shoe opening SH side.

A pair of heel nozzles 28 are disposed on the rear side Y2 of a pair of shoes S. The heel ejection opening 20C of the heel nozzle 28L faces the heel portion SK of the shoe S of the left side X1 from the rear side Y2, and the heel ejection opening 20C of the heel nozzle 28R faces the shoe S of the right side X2 from the rear side Y2 Followed by SK. The front end portion of the positioning portion 38 on the left side X1 contacts the heel portion SK of the shoe S on the left side X1 from the rear side Y2, and the front end portion of the positioning portion 38 on the right side X2 contacts the shoe S of the right side X2 from the rear side Y2. Followed by SK. Thereby, the heel portion SK of the shoe S on the left side X1 is positioned by the positioning portion 38 so as to be spaced apart from the heel ejection opening 20C of the left side X1 by a fixed gap 41 in the front-rear direction Y. The heel portion SK of the shoe S on the right side X2 is also positioned by the positioning portion 38 so as to be spaced apart from the heel ejection opening 20C of the right side X2 by the gap 41.

After the preparation for the cleaning operation is completed, the user operates the operation unit 4C (see FIG. 1) to instruct the shoe washing apparatus 1 to start the cleaning operation. Then, the control unit 40 starts the washing process, and first, the water supply valve 39 is opened to supply water into the storage chamber 11. As a result, the water from the valve plug (not shown) flows into the duct 22 through the water supply passage 24 by the water pressure, flows from the outlet 22A to the storage chamber 11, and is stored in the lower space 11b of the storage chamber 11. Such a conduit 22 doubles as at least a portion of the water supply passage 24. Further, the tap water flowing into the lower space 11b from the outlet 22A of the duct 22 passes through the outflow port 12E, the opening 12G, and the first flow path 32 and reaches the pump 29 (refer to the thick solid arrow in FIGS. 5B and 5C), and the control unit 40 passes The pump 29 is stopped so that the water of the first flow path 32 does not flow at least into the drainage path 37. Therefore, the water level of the water in the lower space 11b rises with the water supply.

When the water surface W in the lower space 11b rises below the predetermined water level of the horizontal nozzle 31 of the rotary nozzle 26, the control unit 40 closes the water supply valve 39 to stop the water supply. As described above, since the detergent is put in the storage chamber 11 in advance, the cleaning liquid generated by dissolving the detergent in water is accumulated in the lower space 11b. A part of the cleaning liquid in the lower space 11b also spreads over the first flow path 32. In addition, the detergent storage chamber (not shown) connected to the water supply passage 24 is provided in the shoe washing apparatus 1, and the detergent contained in the detergent storage chamber can be put into the storage chamber 11 with the tap water at the time of water supply.

Then, the control unit 40 maintains the first flow path 32 and the drain path 37 in a state of being continuously cut in the pump 29, and sucks the cleaning liquid in the lower space 11b of the storage chamber 11 from the first flow path 32 to the second flow. The pump 29 is driven in such a manner that the road 33 and the third flow path 34 are discharged. Then, the cleaning liquid discharged from the first flow path 32 to the second flow path 33 (see the thick one-dot chain line arrow in FIG. 5B) flows into the tower nozzle 30 of the rotary nozzle 26 and rises in the tower nozzle 30, and also throughout Inside each horizontal nozzle 31.

Then, the cleaning liquid is ejected from the ejection port 20A' (see Fig. 4) of the plurality of ejection ports 20A arranged in a row in each of the horizontal nozzles 31 toward the circumferential direction T. Thereby, since each horizontal nozzle 31 receives the thrust of the circumferential direction T, the entire rotary nozzle 26 rotates about the longitudinal axis J. Incidentally, the injection port 20A' for generating the thrust for rotating the rotary nozzle 26 may not be one injection port 20A at one end of the horizontal nozzle 31 at the radially outer side R1, and may be another injection port 20A. During the rotation of the rotary nozzle 26, the left and right holding portions 16 of the holding shoe S are disposed at substantially equal intervals from the tower nozzle 30 in the left-right direction X. Therefore, the shoes S are not in contact with the rotating tower nozzle 30. The extent is far from the tower nozzle 30 (see Fig. 3).

Each of the horizontal nozzles 31 of the rotary nozzle 26 in rotation is indicated by a solid solid arrow from the ejection opening 20A other than the ejection opening 20A', and from the lower side Z2 toward the upper portion SU of each shoe S in the upper space 11A, Wear the shoe opening SH to spray the cleaning solution. Further, the cleaning liquid that rises in the tower nozzle 30 of the rotating rotary nozzle 26 is directed from the upper side Z1 toward the respective shoes S from the respective injection ports 20A of the upper end portion 30A of the tower nozzle 30 as indicated by the thick broken line arrow. The sole SZ and the side SS are sprayed.

Further, the cleaning liquid that has flowed into the third flow path 34 from the first flow path 32 (see the thick broken line arrow in FIGS. 5B and 5D) passes through the inlet pipe portion 36A and the first outlet pipe portion 36B of the joint pipe 36 (refer to FIG. 4). And Figure 5D) extends through the side nozzle 27L and throughout the heel nozzle 28L. The cleaning liquid flowing through the third flow path 34 flows into the fourth flow path 35 (see FIG. 5A) via the inlet pipe portion 36A and the second outlet pipe portion 36C of the joint pipe 36, and then passes through the side nozzle 27R and over the heel. Inside the nozzle 28R.

Then, referring to Fig. 4, in the side nozzle 27L, as indicated by a thick dashed-dotted arrow, the cleaning liquid is ejected from the side ejection opening 20B to the side portion SS of the left side X1 of the shoe S on the left side X1. In the heel nozzle 28L, as indicated by a thick broken line arrow in Fig. 4, the cleaning liquid is ejected from the heel ejection opening 20C to the heel portion SK of the shoe S on the left side X1. In the side nozzle 27R, as indicated by a thick dashed-dotted arrow, the cleaning liquid is ejected from the side ejection opening 20B to the side portion SS of the right side X2 of the shoe S of the right side X2. At the heel nozzle 28R, as indicated by a thick broken line arrow, the washing liquid is ejected from the heel ejection opening 20C to the heel portion SK of the shoe S of the right side X2.

In addition, the cleaning liquid which flows in the third flow path 34 and flows into the inlet pipe portion 36A of the joint pipe 36 is changed in the first outlet pipe portion 36B at a substantially right angle and flows into the side nozzle 27L. The second outlet pipe portion 36C flows in the third flow path 34 and flows into the side nozzle 27R with almost no change in orientation. In this case, the momentum of the cleaning liquid in the inflow-side nozzle 27L can be made weaker than the momentum of the cleaning liquid in the inflow-side nozzle 27R.

Therefore, the inner diameter of the first outlet pipe portion 36B is set larger than the inner diameter of the second outlet pipe portion 36C. Further, the internal space of the first outlet pipe portion 36B is directly connected to the internal space of the side nozzle 27L from the rear side Y2. These internal spaces are arranged along the longitudinal direction of the side nozzle 27 and are superposed from the front-rear direction Y, and therefore, It is possible to reduce the water pressure resistance in these internal spaces. Thereby, the flow rate of the cleaning liquid in the first outlet pipe portion 36B can be increased, and the cleaning liquid of the first outlet pipe portion 36B can be made to extend into the side nozzle 27L without weakening the momentum as indicated by the solid arrow in FIG. Front end. Therefore, the cleaning liquid having substantially the same momentum is ejected from the side ejection openings 20B of the left and right side nozzles 27 to the left and right shoes S.

The shoe S which is sprayed with the cleaning liquid at a high pressure or the dirt of the cleaning liquid removes dirt such as mud or gravel, or the cement is chemically decomposed by the cleaning liquid to perform cleaning. In particular, the cleaning liquid sprayed from each of the injection ports 20A of the horizontal nozzle 31 of the rotating rotary nozzle 26 is continuously leaked in each corner of the outer surface portion on the surface side of each shoe S in the reverse posture, that is, the toe ST , the upper part SU, the wearing shoe SH and the heel part SK. Thereby, therefore, even in various shoes S having different shapes of the surface portions, it is of course possible to wash the entire area of the surface portion of the shoe S by the cleaning liquid entering the internal space SN from the shoe opening SH, and also to clean The internal space SN is the entire area in the shoe S.

Further, the respective side injection ports 20B of the pair of side nozzles 27 spray the cleaning liquid from the left and right direction X toward the side portions SS of the respective shoes S, and the heel ejection openings 20C of the pair of heel nozzles 28 are directed from the rear side Y2 to the respective shoes S. The heel part SK sprays the cleaning solution. Thereby, the side portion SS and the heel portion SK are cleaned by the cleaning liquid on the outer surface portion of the surface side of the shoe S, and the cleaning liquid pair that flows down to the upper portion SU along the side portion SS and the heel portion SK The upper SU and the shoe opening SH are cleaned.

Further, referring to Fig. 2, after the ejection from the respective ejection openings 20A of the horizontal nozzle 31, there is a sole SZ in the place where the cleaning liquid that collides with the cover 14 which is the top of the storage chamber 11 and falls, that is, the outer side of the shoe S Surface part. Further, each of the injection ports 20A of the upper end portion of the tower nozzle 30 of the rotary nozzle 26 rotates integrally with the tower nozzle 30, so that the cleaning liquid can be ejected from the upper side Z1 to a wide range of the sole SZ of each shoe S. The entire area of the sole SZ can be effectively cleaned by these cleaning liquids.

As described above, even if the shoe S is brushed without using a brush or the like, the high-pressure cleaning liquid that is ejected from the respective ejection ports 20 to the shoe S in the storage chamber 11 can maintain the same cleaning power as the case where the shoe S is scrubbed with a brush or the like. And the inside and outside of the entire shoe S are cleaned without any damage. Therefore, it is possible to improve the cleaning power so as not to damage the shoe S.

In particular, the cleaning liquid can be reliably ejected to the side of the shoe S regardless of whether it is the low-cut shoe S1 or the high-top shoe S2 by the plurality of side ejection openings 20B arranged side by side on the respective side nozzles 27. SS. Therefore, regardless of which shoe S is different in the position of the shoe opening SH, the cleaning force can be improved without causing damage.

The heel ejection opening 20C also ejects the cleaning liquid to the heel portion SK of the shoe S, in addition to the side ejection opening 20B ejecting the cleaning liquid to the side portion SS of the shoe S, so that the entire outer surface portion of the shoe S can be further cleaned without fail. . Moreover, the heel portion SK is positioned relative to the heel ejection opening 20C by the positioning portion 38. Thus, regardless of which shoe S of the shape of the heel portion SK is different, the positional relationship between the heel ejection opening 20C and the heel portion SK is made to be ejected from the heel in such a manner as to secure the fixed gap 41. The mouth 20C sprays the optimum positional relationship of the cleaning liquid to the heel portion SK. Thereby, the heel ejection opening 20C can efficiently eject the cleaning liquid to the heel portion SK of the shoe S in the storage chamber 11, so that the cleaning force can be further improved.

In addition, since the holding portion 16 of the internal space SN inserted into the shoe S has a frame shape having a large number of gaps, the cleaning liquid from the respective ejection openings 20A of the horizontal nozzle 31 toward the shoe opening SH is not blocked by the holding portion 16. The flow can smoothly flow into the internal space SN from the shoe opening SH, and can smoothly flow out of the shoe S from the shoe opening SH after flowing in. As in the low-cut shoe S1, if the sole S is tilted from the toe ST side toward the heel SK side toward the lower side Z2, the cleaning liquid in the internal space SN can be worn from the shoes. The mouth SH further smoothly flows out of the shoe S.

Further, during the cleaning process, the control unit 40 may turn on the heater 18 to heat the cleaning liquid in the lower space 11b. In this case, since the washing power can be increased by the warm washing liquid which is poured from the respective injection ports 20 on the shoe S, the shoe S can be further effectively cleaned.

Further, in the storage chamber 11, a partition member 15 is provided between the shoe S and the horizontal nozzle 31 of the rotary nozzle 26. With this configuration, it is possible to prevent the shoe S that has fallen from the holding portion 16 and the shoelace (not shown) of the shoe S from coming into contact with the horizontal nozzle 31, thereby preventing the rotation of the rotary nozzle 26 and the injection from the horizontal nozzle 31. The injection of the cleaning liquid of the port 20. Further, since the partition member 15 has a lattice shape, the washing liquid sprayed from each of the injection ports 20 can reliably reach the shoe S by passing through the lattice eye of the partition member 15. Therefore, even if the partition member 15 is present, the shoe S can be reliably washed by the washing liquid sprayed from the respective injection ports 20 of the horizontal nozzle 31.

The detergent for the cleaning liquid is preferably a low-foaming detergent for washing shoes containing a surfactant as a soap component in a ratio of usually 10% by mass or less. In this case, abnormal foaming of the washing liquid is suppressed, and clogging of each of the injection ports 20 due to foaming of the washing liquid can be prevented, and a decrease in the number of revolutions of the rotary nozzle 26 due to the resistance of the foam can be prevented.

In the cleaning process, after the shoes S in the upper space 11A of the storage chamber 11 are ejected from the respective ejection ports 20, the cleaning liquid overflowing from the shoes S is ejected from the ejection ports 20 into the upper space 11A but is not applied to the shoes S. The cleaning liquid passes through the lattice eye of the partition member 15 and falls into the lower space 11B and is accumulated in the bottom surface portion 12. The pump 29 is continuously driven during the cleaning process. Therefore, the cleaning liquid in the lower space 11B flows into the first flow path 32 through the outflow port 12E and the opening 12G of the bottom surface portion 12, flows through the second flow path 33, the third flow path 34, and the fourth flow path 35 from the rotary nozzle 26 The side nozzles 27 and the respective injection ports 20 of the heel nozzles 28 are ejected into the upper space 11A. Thereby, the cleaning liquid circulates between the upper space 11A and the lower space 11B. Therefore, even if a small amount of the cleaning liquid can be used repeatedly to wash the shoe S, it is possible to improve the water-saving performance.

Foreign matter such as grit that is removed from the shoe S by the ejection of the cleaning liquid follows the cleaning liquid that will flow out from the outflow port 12E to the outside of the storage chamber 11. When the cleaning liquid passes through the outflow port 12E, the filter 25 of the filter unit 17 traps foreign matter from the cleaning liquid. Thereby, it is possible to prevent the foreign matter from clogging the pump 29 and the injection port 20 as the cleaning liquid circulates. The shoe washing apparatus 1 may further include a sheet-shaped second filter 42 composed of a mesh or the like having a mesh smaller than the filter 25. The second filter 42 is disposed in the middle of the cleaning liquid that has passed through the filter 25 before reaching the opening 12G, and is disposed, for example, directly below the filter 25. The second filter 42 captures fine foreign matter contained in the cleaning liquid that has passed through the filter 25. The cleaning liquid that has flowed out of the storage chamber 11 through the filter 25 and the second filter 42 is sent to the respective injection ports 20 by the pump 29 and ejected from the respective injection ports 20 into the storage chamber 11, thereby Ground cycle.

After the circulation of the cleaning liquid continues for a predetermined period of time, the control unit 40 switches the operation of the pump 29 to cause the cleaning liquid of the first flow path 32 to flow to the drainage path 37. Thereby, the cleaning liquid of the lower space 11b passes through the first flow path 32 and the drainage path 37, and is forcibly discharged to the outside of the machine. After such drainage, the control unit 40 stops the pump 29. Thereby, the cleaning process ends. In addition, a drain valve (not shown) that is opened and closed by the control unit 40 and opened during draining may be provided in the middle of the drain passage 37.

When the washing process is completed, the control section 40 starts the rinsing process, executes the water supply again, and accumulates the tap water in the lower space 11b. When the water surface W in the lower space 11b by the water supply reaches a predetermined water level lower than the horizontal nozzle 31 of the rotary nozzle 26, the control unit 40 circulates the tap water as the rinsing water between the upper space 11A and the lower space 11B by the drive pump 29. Thereby, since the rinsing water from the respective ejection ports 20 of the rotary nozzle 26, the side nozzle 27, and the heel nozzle 28 is ejected to the shoe S in the upper space 11A at a high pressure, the shoe S is rinsed by the rinsing water. At this time, the control unit 40 may turn on the heater 18 to heat the rinsing water of the lower space 11B. In this case, the shoe S can be effectively rinsed by pouring warm rinsing water from the respective injection ports 20 onto the shoe S.

After the circulation of the rinsing water continues for a predetermined period of time, the control unit 40 switches the operation of the pump 29 to cause the water in the first flow path 32 to flow to the drain passage 37. Thereby, the rinsing water of the lower space 11B passes through the first flow path 32 and the drain path 37 and is discharged to the outside of the machine. Thereafter, the control unit 40 stops the pump 29. Thus, the rinsing process ends, that is, the entire cleaning process ends.

After the washing process, the control unit 40 starts the liquid removal process by driving the blower unit 23. Thereby, the air outside the machine passes through the suction port 23A and the discharge port 23B of the air blowing portion 23 and is sucked into the duct 22. The air sucked into the duct 22 forms a wind and is directed toward the outlet 22A, and is sent from the outlet 22A into the storage chamber 11. Such a duct 22 also serves as at least a part of the air supply path for feeding the air to the outlet 22A, and also serves as the entire air supply path in this embodiment.

The air sent into the storage chamber 11 is sprayed on the outer surface portion of each shoe S in the upper space 11A or in the shoe S from the shoe opening SH in a state of high pressure after being pressurized by the air blowing portion 23. The internal space SN causes moisture such as a cleaning liquid to leak out from the shoe S. The oozing water is spilled from the shoe S. Therefore, by spraying the air from the duct 22 to each of the shoes S, the shoes S after washing can be effectively deliquoied. The air sent into the storage chamber 11 is finally discharged to the outside of the machine from the exhaust port 4A (see FIG. 1) of the door 4 of the main body 3. In addition, in the liquid removal process, the control unit 40 may turn on the heater 18 to generate hot air in the storage chamber 11. In this case, the shoe S can be further effectively dehydrated by hot air.

When a predetermined time has elapsed after the start of driving of the blower unit 23, the control unit 40 stops the blower unit 23 and ends the de-liquidizing process. Thereby, the washing operation is completed. It should be noted that the control unit 40 may drive the pump 29 at the end of the deliquoring process to discharge the moisture spilled from the shoe S during the deliquoring process out of the machine. After the cleaning operation is completed, the user pulls the main body 3 to the pull-out position (not shown) to open the input and take-out port 13 of the washing tub 5, and takes out the shoe S in the storage chamber 11 from the input and take-out port 13.

As described above, in the shoe washing apparatus 1, when the shoe S is first stored in the storage chamber 11 and held by the holding portion 16, even if the shoe S is not moved in the storage chamber 11, the series of cleaning can be performed. Running. Further, in the shoe washing apparatus 1, since the shoe S in the storage chamber 11 is held by the holding portion 16 in the reverse posture, the storage chamber 11 can be compared with the case where the shoe S is held in the vertical posture. Since the height dimension is suppressed to be small, the entire shoe washing apparatus 1 can be made compact.

Next, the details of the holding unit 16 will be described. FIG. 6 is a perspective view of the holding portion 16. FIG. 7 is a plan view of the holding portion 16. FIG. 8 is a right side view of the holding portion 16. In FIGS. 6 to 8 , the boundary between the root portion 16A and the intermediate portion 16C and the boundary between the distal end portion 16B and the intermediate portion 16C are illustrated by solid lines in the respective holding portions 16 . Referring mainly to Fig. 6, the root portion 16A has an upper root frame 16D and a lower root frame 16E. The distal end portion 16B has a distal end frame 16F. The intermediate portion 16C has an upper intermediate frame 16G, a lower intermediate frame 16H, and a coupling frame 16I.

Each of the upper root frame 16D and the lower root frame 16E is formed of a linear wire extending horizontally in the front-rear direction Y, and a pair is arranged side by side. The pair of right and left upper root frames 16D are arranged in parallel at the same height position. The pair of right and left lower root frames 16E are arranged in parallel at the same position. The lower root frame 16E is disposed at a position slightly lower than the upper root frame 16D. The left and right intervals of the pair of upper root frame 16D are the same as the left and right intervals of the pair of lower root frames 16E. Therefore, the lower root frame 16E of the left side X1 is located immediately below the upper root frame 16D of the left side X1, and the lower root frame 16E of the right side X2 is located directly below the upper root frame 16D of the right side X2. It should be noted that the upper root frame 16D and the lower root frame 16E which are on the same side in the left-right direction X may not be disposed at the same position in the left-right direction X. The space sandwiched by the upper root frame 16D of the left side X1 and the lower root frame 16E and the upper root frame 16D of the right side X2 and the lower root frame 16E from the left-right direction X is the fitting portion 16J provided in the root portion 16A. The fitting portion 16J is in a state of being open to both sides in the vertical direction Z.

The disk-shaped mounting base 45 having the thickness direction in the front-rear direction Y is connected to the rear end portion of the upper root frame 16D and the lower root frame 16E. The mounting table 45 is a part of the holding portion 16 or a part of the rear wall 7 (refer to FIG. 2) of the washing tub 5, and is fixed to the washing tub 5. The pair of upper root frame 16D is disposed symmetrically with respect to the virtual reference axis K extending through the center of the circle of the mounting table 45 in the front-rear direction Y, and the pair of lower root frames 16E are also symmetrical with respect to the reference axis K. Ground configuration (see Figure 7).

The distal end frame 16F is formed of a linear wire extending horizontally in the front-rear direction Y, and a pair is arranged side by side. The pair of left and right distal end frames 16F are arranged bilaterally symmetrically with reference to the reference axis K so as to be parallel to the same height position (see FIG. 7). The left-right interval D1 of the pair of distal frames 16F is narrower than the left-right interval D2 of the pair of upper root frames 16D (see FIG. 7). The interval D1 is set such that the end portion 16B is narrower than the inner space SN of the shoe S which is the narrowest in the internal space SN to be cleaned. The top frame 16F is disposed at a position higher than the upper root frame 16D. The difference H1 between the height positions of the upper root frame 16D and the top frame 16F is set to be substantially the same as the height S2 of the shoe S S from the sole S2 of the high-top shoe S2 which is assumed to be the cleaning target to the shoe opening SH. (Refer to Figure 8).

Each of the upper intermediate frame 16G and the lower intermediate frame 16H is formed of a wire that extends obliquely toward the lower rear side, and a pair of left and right sides are arranged. The pair of right and left intermediate frames 16G are arranged bilaterally symmetrically with respect to the reference axis K (see FIG. 7), and are completely overlapped when viewed from the side (see FIG. 8). The pair of left and right lower intermediate frames 16H are also arranged bilaterally symmetrically with respect to the reference axis K, and are completely overlapped when viewed from the side (see FIG. 8).

Each of the upper intermediate frames 16G integrally has a lower portion 16K, an upper portion 16L, and a midway portion 16M. In FIGS. 6 to 8, the boundary between the lower portion 16K and the intermediate portion 16M and the boundary between the upper portion 16L and the intermediate portion 16M are illustrated by broken lines.

The lower portion 16K is formed in a linear shape that extends obliquely toward the lower rear side without changing the position of the left-right direction X. The lower end portion of the lower portion 16K of the upper intermediate frame 16G on the left side X1 is bently connected to the front end of the upper root frame 16D of the left side X1 toward the rear side Y2. The lower end portion of the lower portion 16K of the upper intermediate frame 16G on the right side X2 is curvedly connected to the front end of the upper root frame 16D of the right side X2 toward the rear side Y2. The interval D3 between the pair of left and right lower portions 16K is the same as the interval D2 between the pair of right and left upper root frames 16D (see FIG. 7).

The upper portion 16L is formed in a linear shape that extends obliquely toward the lower rear side without changing the position of the left-right direction X. The upper end portion of the upper portion 16L of the upper middle half frame 16G of the left side X1 is bently connected to the rear end of the top end frame 16F of the left side X1 toward the front side Y1. The upper end portion of the upper portion 16L of the upper middle half frame 16G of the right side X2 is bently connected to the rear end of the top end frame 16F of the right side X2 toward the front side Y1. The interval D4 between the pair of right and left upper portions 16L is the same as the interval D1 between the pair of left and right distal end frames 16F (see FIG. 7).

The intermediate portion 16M is formed in a linear shape that extends away from the reference axis K toward the outside in the left-right direction X and obliquely toward the lower rear side. In each of the upper intermediate frames 16G, the lower end of the intermediate portion 16M is connected to the upper end of the lower portion 16K, and the upper end of the intermediate portion 16M is connected to the lower end of the upper portion 16L. The interval D5 between the pair of left and right intermediate portions 16M is set to gradually increase toward the lower rear side (see FIG. 7).

The pair of left and right lower intermediate frames 16H are disposed one by one directly below the pair of right and left intermediate frames 16G, and the upper intermediate frame 16G and the lower intermediate frame 16H are completely overlapped in plan view, but may be slightly offset. Each of the lower intermediate frames 16H integrally has a lower portion 16N, an upper portion 16P, and a midway portion 16Q. In FIGS. 6 to 8, the boundary between the lower portion 16N and the intermediate portion 16Q and the boundary between the upper portion 16P and the intermediate portion 16Q are illustrated by broken lines.

The lower portion 16N is formed in an arc shape that gradually bends and extends toward the lower rear side without changing the position of the left-right direction X. The rear end of the lower portion 16N of the lower middle half frame 16H of the left side X1 is connected to the front end of the lower root frame 16E of the left side X1. The rear end of the lower portion 16N of the lower half intermediate frame 16H of the right side X2 is connected to the front end of the lower root frame 16E of the right side X2. The lower portion 16N of each of the lower intermediate frames 16H may be located directly below the lower portion 16K of the upper intermediate frame 16G on the same side in the left-right direction X. The front ends of the lower portion 16N and the lower portion 16K may be at the same position in the front-rear direction Y, and the rear ends of the lower portion 16N and the lower portion 16K may be at the same position in the front-rear direction Y (refer to FIG. 8). The upper and lower intervals D6 of the lower portion 16N and the lower portion 16K are set to be wider as they are toward the front side Y1 (refer to FIG. 8).

The upper portion 16P is formed in a linear shape that extends obliquely toward the lower rear side without changing the position of the left-right direction X. The upper end portion of the upper portion 16P of the lower intermediate frame 16H on the left side X1 is bent in an arc shape to the front end of the distal end frame 16F of the left side X1. The upper end portion of the upper portion 16P of the lower intermediate frame 16H on the right side X2 is bent in an arc shape to the front end of the distal end frame 16F of the right side X2. The upper portion 16P of each of the lower intermediate frames 16H may be located directly below the upper portion 16L of the upper intermediate frame 16G on the same side in the left-right direction X and extend in parallel with the upper portion 16L. The rear ends of the upper portion 16P and the upper portion 16L may be at the same position in the front-rear direction Y (refer to FIG. 8).

The intermediate portion 16Q is formed in a linear shape that extends away from the reference axis K toward the outside in the left-right direction X and obliquely toward the lower rear side. In each of the lower intermediate frames 16H, the lower end of the intermediate portion 16Q is connected to the upper end of the lower portion 16N, and the upper end of the intermediate portion 16Q is connected to the lower end of the upper portion 16P. The intermediate portion 16Q of each of the lower intermediate frames 16H may be located immediately below the intermediate portion 16M of the upper intermediate frame 16G on the same side in the left-right direction X and extend substantially parallel to the intermediate portion 16M. The intermediate portion 16Q and the intermediate portion 16M can be at the same position in the front-rear direction Y, and the intermediate portion 16Q and the intermediate portion 16M can be at the same position in the front-rear direction Y (see FIG. 8).

The intermediate portion 16M of the right and left intermediate frame 16G and the intermediate portion 16Q of the left and right lower intermediate frames 16H are the fitting portions 16R provided in the intermediate portion 16C. The fitting portion 16R is configured such that the root portion 16A toward the lower rear side gradually widens to the left and right. The minimum width of the fitting portion 16R, specifically, the minimum width D7 of the front end portion of the fitting portion 16R (see FIG. 7) is set to be the same as the shoe S of the shoe S which is the narrowest as the shoe opening SH of the cleaning target. The width of the SH is narrower. The maximum width of the fitting portion 16R, specifically, the maximum width D8 of the rear end portion of the fitting portion 16R (refer to FIG. 7) is set to be the same as the shoe S which is the widest the shoe opening SH of the cleaning target. The width of the port SH is wider.

The connecting frame 16I is composed of, for example, a wire extending in a substantially C-shaped arc shape. As an example, the connection frame 16I is bridged between the upper portion 16L of each of the upper intermediate frames 16G and the upper portion 16P of each of the lower intermediate frames 16H, and is bridged between the pair of upper intermediate frames 16G, and is bridged between the pair of lower intermediate frames. Between 16H. Thereby, the entire holding portion 16 is reinforced, so that it is difficult to be deformed in the up, down, left, and right directions.

As described above, before the start of the washing operation, the user stores the shoe S in the storage chamber 11, and at this time, after the distal end portion 16B of the holding portion 16 is inserted from the lower side Z2 to the shoe opening SH of the shoe S, The internal space SN of the shoe S is inserted (refer to FIG. 2). Since the distal end portion 16B is set to be narrower than the internal space SN, it is easy to insert the internal space SN. As shown in Fig. 8, the distal end portion 16B is inserted into the holding portion 16 after the internal space SN of the shoe S, and the distal end frame 16F of the distal end portion 16B supports the sole SZ from the lower side Z2 in a state of being parallel or substantially parallel to the sole SZ. The fitting portion 16R is fitted into the shoe opening SH, and the heel portion SK is fitted into the fitting portion 16J from the upper side Z1. Thereby, the height direction of the shoe S in the accommodation chamber 11, that is, the position of the up-down direction Z remains stable. In particular, since the distal end portion 16B of the internal space SN is disposed closer to the back side of the toe ST than the center of gravity SG of the shoe S, the shoe S held by the holding portion 16 is less likely to be shaken.

Further, the heel portion SK of the shoe S is fitted into the fitting portion 16J and sandwiched by at least a pair of right and left upper root frames 16D. In addition, the pair of left and right intermediate portions 16Q and/or the intermediate portion 16M of the fitting portion 16R that is widened toward the root portion 16A in the intermediate portion 16C of the holding portion 16 are fitted into the shoe opening SH of the shoe S, so that the shoes are worn. The port SH is widened left and right (see Fig. 7). Thereby, the shoe S becomes difficult to tilt to the left and right, and the position of the shoe S in the lateral direction in the storage chamber 11, that is, the position in the left-right direction X remains stable.

As described above, in the shoe washing apparatus 1, the shoe S in the storage chamber 11 can be cleaned by the holding portion 16 while being held at a stable position. Such a holding portion 16 can be simply constructed of a wire.

Further, in the holding portion 16, the root portion 16A is disposed at a position lower than the distal end portion 16B, and the intermediate portion 16C is configured to be inclined from the distal end portion 16B toward the root portion 16A toward the lower side Z2. Thus, regardless of whether it is the low-cut shoe S1 or the high-top shoe S2, the heel portion SK of the shoe S is fitted into the fitting portion 16J of the root portion 16A, and the tip end portion 16B supports the sole SZ from the lower side Z2, and the midway portion 16C is embedded. The hinge 16R is fitted into the shoe opening SH of the shoe S. Therefore, regardless of which shoe S having a different height of the shoe opening SH, the shoe S can be cleaned while being held in a stable position by the holding portion 16.

The low-cut shoe S1 is held by the holding portion 16 such that the sole SZ is inclined rearward and downward, and the high-top shoe S2 is held by the holding portion 16 so that the sole SZ is substantially horizontal, but passes through the middle portion of the holding portion 16. The inclination of the 16C, the difference in the height of the shoe opening SH is absorbed, whereby the respective postures of the shoe S1 and the shoe S2 are substantially the same. Further, the distal end portion 16B of the holding portion 16 and the side injection port 20B of the side nozzle 27, in particular, the side injection port 20B of the row L1 of the upper side Z1 are substantially at the same position in the vertical direction Z. Therefore, in each of the shoe S1 and the shoe S2 that support the sole SZ by the distal end portion 16B, the position of the washing liquid sprayed from the side ejection opening 20B does not change greatly, so whether it is the shoe S1 or the shoe S2, It ensures even cleaning performance.

Further, referring to Fig. 3, when the rotary nozzle 26 is rotated during the cleaning operation, the cleaning liquid sprayed from the injection port 20 provided in the rotary nozzle 26 is continuously held by the holding portions 16 as indicated by a thick broken line arrow. The shoe S is in a stable position, so that the entire shoe S can be cleaned without fail. The protective portion 21 disposed between the shoe S held by each of the holding portions 16 and the rotary nozzle 26 protects the rotary nozzle 26 from the shoe S. Further, since the shoe S can be prevented from being tilted toward the rotary nozzle 26 by the protection portion 21, the shoe washing device 1 can perform cleaning while holding the shoe S in the storage chamber 11 at a further stable position. The protection portion 21 may be integrated with the holding portion 16. In addition, in order to protect the rotating nozzle 26 from the shoe S, and to prevent the flow of the cleaning liquid from the injection port 20A of the upper end portion 30A of the tower nozzle 30 of the rotary nozzle 26, the upper end of the protection portion 21 is set. The injection port 20A lower than the lower end of the upper end portion 30A has substantially the same height position as the sole SZ. Further, the upper portion of the shoe S sandwiched between the left and right sides of the protective portion 21 is formed to be tapered toward the upper side Z1 so as to be along the side shape of the shoe nozzle 30 side of each shoe S. Thereby, when the shoe S is detached from the holding portion 16, the shoe S can be prevented from hanging on the upper portion of the protecting portion 21.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims.

For example, in the above embodiment, the shoe washing apparatus 1 is incorporated in a base (not shown) of the washing machine for use, but may be incorporated in the washing machine itself. In these cases, the control unit 40 of the shoe washing apparatus 1 may also pass. The cleaning operation is performed by receiving an instruction from the control unit of the washing machine. Of course, the shoe washing apparatus 1 may be separately provided without being assembled in the base of the washing machine or the washing machine. In this case, the frame 2 may be omitted, so that the main body 3 cannot slide.

Further, the present invention is not limited to the shoe washing apparatus 1 that washes the shoe S by the washing liquid sprayed from the injection port 20, and can be applied to a shoe washing apparatus of another configuration in which the shoe S is scrubbed by a brush or the like.
