The present invention has been made in view of the above circumstances, and an object thereof is to provide a shoe washing apparatus capable of improving maintainability.

Solution to solve the problem

The present invention relates to a shoe washing apparatus comprising: a storage compartment for storing a shoe; and a holding portion in which the shoe is held in an inverted posture in which the sole is oriented upward; and a rotating nozzle for the storage The hollow rotary nozzle extending from the bottom surface portion of the storage chamber to the upper side and rotating around the vertical axis can be separated into an upper end of the injection port of the shoe in which the cleaning liquid in the rotary nozzle is sprayed into the storage chamber. And a main body portion that is rotatably supported by the bottom surface portion on the lower side of the upper end portion; and a sealing member that closes a gap between the upper end portion and the main body portion.

Further, the present invention is characterized in that the upper end portion includes a first divided body and a second divided body joined together with the longitudinal axis, and the ejection opening is in the first divided body and the second divided portion The manner in which the bodies are asymmetrically arranged is provided in the first divided body and the second divided body, respectively.

Further, the present invention is characterized in that the injection port includes a first injection port, the upper end portion is disposed at a position higher than a sole of the shoe in the storage chamber, and sprays the cleaning liquid obliquely downward; and the second injection The port is disposed at a position lower than the first injection port at the upper end portion and sprays the cleaning liquid toward the horizontal direction or obliquely downward.

Further, the present invention is characterized in that a support portion is provided on a bottom surface portion of the storage chamber, and the support portion has an insertion hole into which a lower end portion of the main body portion is inserted, and rotatably supports the main body portion. The lower end portion of the main body portion is provided with a sliding portion having a polygonal contour that surrounds the axis and protrudes from the outer peripheral surface of the lower end portion in a plan view angle, as the rotating nozzle rotates The inner peripheral portion of the insertion hole is wiped.

Effect of the invention

According to the invention, in the shoe washing apparatus, the holding portion holds the shoe in the storage chamber in a reverse posture in which the sole is turned toward the upper side. When the rotary nozzle extending upward from the bottom surface portion of the storage chamber is rotated about the vertical axis, the cleaning liquid in the rotary nozzle ejected from the ejection port at the upper end portion of the rotary nozzle is continuously leaked on the shoe held by the holding portion. Therefore, the shoes can be cleaned without fail. The rotating nozzle is in a state in which the upper end portion provided with the injection port and the main body portion rotatably supported by the bottom surface portion of the storage chamber are connected via the sealing member, and the rotary nozzle can be separated into the upper end portion and the main body portion. . Therefore, when it is desired to maintain the upper end portion of the rotary nozzle, the upper end portion or even the inside thereof can be maintained without removing the entire rotary nozzle from the storage chamber and removing only the upper end portion. Therefore, it is possible to improve maintenance.

Further, according to the present invention, the upper end portion of the rotary nozzle is configured by joining the first divided body and the second divided body respectively provided with the injection ports by sandwiching the vertical axis which is the center of rotation of the rotary nozzle. The injection port provided in the first divided body is disposed asymmetrically with the injection port provided in the second divided body. With this configuration, the momentum of the cleaning liquid ejected from the ejection opening of the first divided body and the momentum of the cleaning liquid ejected from the ejection opening of the second divided body can be unbalanced. Therefore, when the rotating nozzle during the rotation is inclined, The posture of the rotary nozzle can be corrected by the difference in momentum of these cleaning liquids in order to eliminate the inclination of the rotary nozzle.

Further, according to the present invention, when the first injection port disposed at a position higher than the sole of the shoe in the storage chamber among the injection ports provided at the upper end portion of the rotary nozzle sprays the cleaning liquid obliquely downward, the cleaning liquid is dripped The sole is so able to clean the sole with a cleaning solution. Further, when the second injection port disposed at a position lower than the first injection port at the upper end portion of the rotary nozzle sprays the cleaning liquid toward the horizontal direction or obliquely downward, the cleaning liquid is dripped on the side of the shoe, so that it can be washed The liquid is washed to the side.

Further, according to the present invention, in the rotary nozzle, the lower end portion of the main body portion is supported by the support portion so as to be rotatable about the vertical axis in a state of being inserted into the insertion hole of the support portion of the bottom surface portion of the storage chamber, in the rotary nozzle At the time of rotation, the sliding portion provided at the lower end portion of the main body portion slides the inner peripheral portion of the insertion hole. The wiper portion has a polygonal outline that surrounds the longitudinal axis and protrudes from the outer peripheral surface of the lower end portion of the main body portion in a plan view, and thus the inner peripheral portion of the insertion hole is swept at a corner portion in the polygon. Thereby, the portion of the sliding portion that slides the inner peripheral portion of the insertion hole can be suppressed to be small. Therefore, the abrasion of the sliding portion is reduced and the life of the sliding portion is extended, so that the frequency of the maintenance sliding portion is lowered. Therefore, it is possible to improve maintenance.

The protection portion 21 is placed on the partition member 15 and disposed in the upper space 11A of the storage chamber 11, and surrounds a part of the tower nozzle 30 of the rotary nozzle 26. Specifically, the protection portion 21 surrounds and protects the lower portion 30B by being disposed between the lower portion 30B of the lower side Z2 of the upper end portion 30A of the injection port 20A and the pair of holding portions 16 disposed in the tower nozzle 30 (also Refer to Figure 3). The protection portion 21 may be a member separate from the partition member 15 or may be integrated with the partition member 15.

The duct 22 is formed in a tubular shape extending in the up-and-down direction Z, and is fixed to the rear wall 7 of the washing tub 5 from the rear side Y2. An outlet 22A is formed at a lower end portion of the duct 22. The outlet 22A is disposed in a lower portion of the front surface portion of the rear wall 7 as an example of the inner wall portion of the storage chamber 11, and is in a state of being communicated with the lower space 11B in the storage chamber 11 from the rear side Y2.

The blower unit 23 is a so-called fan, and is disposed outside the washing tub 5, and is fixed to the upper end portion of the duct 22 from the upper side Z1. A suction port 23A is formed on the rear surface of the air blowing portion 23, and a discharge port 23B facing the inner space of the duct 22 from the upper side Z1 is formed on the lower surface of the air blowing portion 23 (see FIG. 5A).

The water supply passage 24 is a pipe extending from a valve plug (not shown) such as a faucet, and is connected to a portion of the pipe 22 that is connected to the lower side Z2 of the portion of the discharge port 23B of the blower portion 23 from the left side X1 (refer to FIG. 5A). ). In addition, the water supply passage 24 may be directly connected to 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 coupled 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 above-described drain passage 37 are slidable based on the main body 3, and are set to be somewhat longer to some extent.

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 air blowing 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 liquid removing 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. The upper space 11A of the chamber 11. At this time, the user inserts the distal end portion 16B of each holding portion 16 from the lower side Z2 to the shoe opening SH of the shoe S, and then inserts it into the internal space SN of the shoe S so as to face 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 substantially horizontal 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, the preparation for the washing operation is completed.

In the shoe washing apparatus 1 in which the preparation for the washing operation is completed, 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. Each of the horizontal nozzles 31 of the rotary nozzle 26 is disposed at a position lower than the shoes S, and the ejection openings 20A of the horizontal nozzles 31 are disposed from the lower side Z2 toward the upper portion SU and the shoe opening SH of the shoes S.

The pair of side nozzles 27 are disposed on both sides of the pair of shoes S in the storage chamber 11, that is, on 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 on 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 openings 20B of the side nozzles 27R are arranged in a direction substantially along the longitudinal direction of the shoe S of the right side X2, and face the side portion SS of the right side X2 of the shoe S from the right side X2. The side injection port 20B of the row L1 of the upper side Z1 of each side nozzle 27 is disposed to overlap the portion of the side portion SS on the sole SZ in a side view. In particular, the side injection port 20B of the front end in the row L1 is disposed to overlap the portion of the side portion SS on the toe ST, and the side injection port 20B at the rear end in the row L1 overlaps with the portion of the side portion SS that is adjacent to the heel portion SK. Ground configuration. 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 from a side view.

A pair of heel nozzles 28 are disposed on the rear side Y2 of the 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 is in contact with 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 is from the rear side Y2 and the shoe S of the right side X2. The heel is in contact with 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 the fixed gap 41 in the front-rear direction Y. The heel portion SK of the shoe S of 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 of the washing operation is completed, the user operates the operation unit 4C (see FIG. 1) to instruct the shoe washing apparatus 1 to start the washing 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. Thereby, water from the valve plug (not shown) passes through the water supply passage 24 through the water pressure, flows into the duct 22, flows down 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 to a predetermined water level lower than 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 into the storage chamber 11 in advance, a cleaning liquid generated by dissolving the detergent in water is stored 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 compartment 11 with the tap water at the time of water supply. Inside.

Next, the control unit 40 maintains the first flow path 32 and the drain path 37 in the pump 29 in a state of being continuously cut, and drives the pump 29 so that the washing liquid in the lower space 11B of the storage chamber 11 is sucked from the first flow path 32 and discharged to the same. The second flow path 33 and the third flow path 34. 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 horizontal nozzle 31 toward the side in the circumferential direction T. Thereby, each horizontal nozzle 31 receives the thrust of the circumferential direction T, and therefore 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, so that the respective shoes S are not in contact with the rotating tower nozzle 30, It is disposed away from the tower nozzle 30 (refer to 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 rising 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 a 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 (see FIG. 4 and Figure 5D) extends through the side nozzles 27L and throughout the heel nozzles 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 nozzle 28R. Inside.

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.

It should be noted that the cleaning liquid flowing in the third flow path 34 and flowing into the inlet pipe portion 36A of the joint pipe 36 is oriented at a substantially right angle in the first outlet pipe portion 36B and flows into the side nozzle 27L, and at the second outlet. The tube 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 to be 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 in the longitudinal direction of the side nozzle 27 and are arranged to overlap from the front-rear direction Y. The reduction in water pressure resistance in these internal spaces. Thereby, the flow rate of the cleaning liquid in the first outlet pipe portion 36B is increased, and the cleaning liquid of the first outlet pipe portion 36B can extend over the front end portion in the side nozzle 27L as indicated by the solid arrow in FIG. Reduce momentum. 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 after the cleaning liquid is sprayed at a high pressure removes dirt such as mud or gravel by the momentum of the cleaning liquid, or chemically decomposes the dirt by the cleaning liquid to perform cleaning. In particular, the cleaning liquid sprayed from each of the injection ports 20A of the horizontal nozzles 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 if the shoes S having different shapes of the surface portions are different, 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 inside. The 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 to the side portions SS of the respective shoes S, and the heel ejection openings 20C of the pair of heel nozzles 28 eject the cleaning liquid from the rear side Y2. To the heel portion SK of each shoe S. Thus, the outer surface portion on the surface side of the shoe S is cleaned by the cleaning liquid to clean the side portion SS and the heel portion SK, and also to the cleaning liquid flowing down to the upper portion SU along the side portion SS and the heel portion SK. To clean the upper SU and wear the shoe SH.

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 destination of the cleaning liquid that collides with the cover 14 which is the top of the storage chamber 11, that is, the back of the shoe S The outer surface of the side. Further, each of the injection ports 20A of the upper end portion of the tower nozzle 30 of the rotary nozzle 26 is rotated 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. With these cleaning liquids, the entire area of the sole SZ can be effectively cleaned.

By the above, even if the shoe S is not wiped by 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 cleaning power equivalent to 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, by the plurality of side ejection openings 20B arranged side by side on the respective side nozzles 27, the cleaning liquid can be reliably ejected to the side of the shoe S regardless of the low-cut shoe S1 or the high-top shoe S2. Department 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, except that the side ejection opening 20B sprays the cleaning liquid to the side portion SS of the shoe S, so that the entire outer surface of the shoe S can be further cleaned without fail unit. Moreover, the heel portion SK is positioned with respect to the heel ejection opening 20C by the positioning portion 38. Therefore, 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 the shoe from the manner of securing the fixed gap 41 as described above. The positional relationship is optimal with the injection port 20C injecting 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.

It is to be noted that the holding portion 16 inserted into the internal space SN of the shoe S has a frame shape having a large number of gaps, so that the cleaning liquid from the respective ejection openings 20A of the horizontal nozzle 31 toward the shoe opening SH can be directed from the shoe opening SH The inside of the internal space SN smoothly flows in, and can smoothly flow out from the shoe opening SH to the outside of the shoe S after the inflow, without being blocked by the holding portion 16. 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 port SH flows out smoothly to the outside 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, the cleaning power can be increased by the hot cleaning liquid which is poured from the respective injection ports 20 on the shoe S, so that 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. Thereby, it is possible to prevent the shoe S that has fallen due to accidental detachment 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 used 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 cleaning liquid is suppressed, and clogging of each of the injection ports 20 due to the foam of the cleaning 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, the cleaning liquid that has been ejected from the respective ejection openings 20 to the shoe S in the upper space 11A of the storage chamber 11 and then ejected from the ejection openings 20 into the upper space 11A but not applied to the shoe S is cleaned. The 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 continues to be 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 the amount of the cleaning liquid is small, the shoe S can be washed and reused by circulation, so that the water-saving performance can be improved.

The foreign matter such as grit that has been 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 circulating together with the cleaning liquid to block the malfunction of the pump 29 and the injection port 20. The shoe washing apparatus 1 may further include a sheet-shaped second filter 42 composed of a mesh or the like whose mesh is thinner 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 passed through the filter 25 and the second filter 42 and flows out to the outside of the storage chamber 11 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, as described above. Loop like that.

The control unit 40 switches the operation of the pump 29 so that the cleaning liquid of the first flow path 32 flows to the drain path 37 after the circulation of the cleaning liquid continues for a predetermined period of time. 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 unit 40 starts the rinsing process, and executes the water supply again to accumulate the tap water in the lower space 11B. When the water surface W in the lower space 11B reaches the predetermined water level lower than the horizontal nozzle 31 of the rotary nozzle 26 by the water supply, the control unit 40 drives the pump 29 to circulate the tap water between the upper space 11A and the lower space 11B as the rinsing water. Thereby, the rinsing water from the respective injection ports 20 of the rotary nozzle 26, the side nozzle 27, and the heel nozzle 28 is sprayed at a high pressure to the shoe S in the upper space 11A, and thus 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, by pouring hot rinsing water onto the shoe S from each of the ejection openings 20, the shoe S can be effectively rinsed.

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 so that the water of the first flow path 32 flows to the drain path 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. Thereby, the rinsing process, that is to say 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 introduced into the duct 22. The air introduced into the duct 22 becomes air and is directed toward the outlet 22A, and is sent into the storage chamber 11 from the outlet 22A. 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 ejected into the outer surface portion of each shoe S in the upper space 11A by the high pressure state pressurized by the air blowing portion 23, or flows into the inner space SN of the shoe S from the shoe opening SH. The water such as the cleaning liquid is oozing out from the shoe S. The oozing water is spilled from the shoe S. Therefore, by spraying air from the duct 22 to each shoe S, the shoe S after washing can be effectively deliquored. 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 desorbed 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 to end 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 to the outside of the machine. After the completion of the washing operation, 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 in 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, the shoe S in the storage chamber 11 is held in the inverted posture by the holding portion 16, and therefore the height dimension of the storage chamber 11 can be suppressed as compared with the case where the shoe S is held in the vertical posture. Since it is small, the entire shoe washing apparatus 1 can be made compact.

Next, the details of the rotary nozzle 26 will be described. FIG. 6 is a perspective view of the rotary nozzle 26, and FIGS. 7A and 7B are exploded perspective views of the rotary nozzle 26 when viewed from opposite sides. The rotary nozzle 26 is a hollow body having the tower nozzle 30 and the two horizontal nozzles 31 as described above. The upper end portion 30A in which the injection port 20A is provided in the tower nozzle 30 is also the upper end portion 26A of the rotary nozzle 26. Hereinafter, a portion other than the upper end portion 26A of the rotary nozzle 26, that is, the lower portion 30B of the tower nozzle 30 and the two horizontal nozzles 31 will be referred to as a main body portion 26B. The main body portion 26B is located on the lower side Z2 of the upper end portion 26A. As for the rotary nozzle 26, as shown in Figs. 7A and 7B, the upper end portion 26A and the main body portion 26B can be separated, instead of being an integral member.

Fig. 8 is a cross-sectional view taken along line E-E of Fig. 1; The upper end portion 26A is a tubular hollow body extending in the longitudinal direction, and the upper end of the upper end portion 26A is closed. At the lower end of the upper end portion 26A, an opening 26C is formed in which the inner space of the upper end portion 26A is opened to the lower side Z2. In the upper end portion 26A, the root portion 26D in which the opening 26C is formed is formed thicker than the portion 26E on the upper side Z1 of the root portion 26D (see Figs. 7A and 7B).

Fig. 9 is a plan view of the upper end portion 26A. The longitudinal axis J passes through the center of the upper end portion 26A in a plan view. The upper end portion 26A has a two-divided structure composed of the first divided body 26F and the second divided body 26G. The first divided body 26F and the second divided body 26G are groove-like shapes that are raised in the radial direction outward R1 and extend in the longitudinal direction, and have substantially the same size and shape as each other (see FIGS. 7A and 7B). The first divided body 26F opposed to the vertical direction axis J and the second divided body 26G are joined by welding or the like to form the upper end portion 26A. The joint portion 26H of the first divided body 26F and the second divided body 26G is formed in a flange shape that protrudes outward in the radial direction R1, and has a substantially U-shaped whole in the vertical direction in FIGS. 6 , 7A, and 7B. shape.

In the outer peripheral surface of the upper end portion 26A, an injection port 20A is provided in a portion corresponding to the first divided body 26F and the second divided body 26G, respectively. The injection port 20A provided in the first divided body 26F and the injection port 20A provided in the second divided body 26G are arranged asymmetrically with respect to the vertical axis J. As an example, in this embodiment, the number of the ejection openings 20A and the height position are different between the first divided body 26F and the second divided body 26G. Needless to say, the same number of injection ports 20A may be provided in the first divided body 26F and the second divided body 26G, respectively. In this case, even if the ejection openings 20A are staggered in the respective first divided body 26F and second divided body 26G, The height position also allows the injection port 20A to be asymmetrically arranged in the first divided body 26F and the second divided body 26G. In this embodiment, referring to FIG. 6 and FIG. 7A, in the region where the first divided body 26F avoids the joint portion 26H and is located on the upper side Z1 of the root portion 26D, two injection ports 20A are arranged side by side. Referring to Fig. 7B and Fig. 8, in the region where the second divided body 26G avoids the joint portion 26H and is located on the upper side Z1 of the root portion 26D, the height of the second divided body 26G is shifted from the respective injection ports 20A of the first divided body 26F. One injection port 20A.

The upper two injection ports 20A of the three injection ports 20A of the second divided body 26G are collectively disposed on the upper end side of the upper end portion 26A, and the remaining one injection port 20A is disposed away from the root portion 26D side. The injection port 20A of the upper side Z1 of the two injection ports 20A of the first divided body 26F is disposed at a height position between the upper two injection ports 20A of the second divided body 26G, and the injection port 20A of the lower side Z2 is disposed at A position slightly higher than the ejection opening 20A of the lower end of the second divided body 26G. The injection port 20A of the upper side Z1 of the first divided body 26F and the upper two injection ports 20A of the second divided body 26G are referred to as a first injection port 20D, and the first divided body 26F and the second divided body 26G are respectively The lowermost injection port 20A is referred to as a second injection port 20E.

Referring to Fig. 7A and Fig. 7B, in the main body portion 26B, the end portion of the radially inner side R2 of each horizontal nozzle 31 is connected to the upper portion Z1 of the lower end portion 30C of the lower portion 30B in the lower portion 30B of the tower nozzle 30. The pair of horizontal nozzles 31 are integrated by the ends of the radially inner side R2 of the pair of horizontal nozzles 31 being connected to each other. An opening 30D that opens the inner space of the lower portion 30B to the upper side Z1 is formed on the upper end surface of the lower portion 30B. On the outer peripheral surface of the upper end portion of the lower portion 30B, a groove 30E extending in the circumferential direction T is formed at a position on the lower side Z2 of the opening 30D. Although there is only one groove 30E in this embodiment, a plurality of grooves 30E may be formed in a row. On the outer peripheral surface of the lower portion 30B, a region of the lower side Z2 of the groove 30E is provided with a rib 30F that protrudes toward the radially outer side R1 and extends in the vertical direction Z. A plurality of ribs 30F are present, and are arranged at equal intervals in the circumferential direction T. The lower end of each rib 30F is connected to the upper surface of the horizontal nozzle 31. Thereby, the main body portion 26B is reinforced, so that the deflection of the tower nozzle 30 and the horizontal nozzle 31 is suppressed.

The rotary nozzle 26 also includes a sealing member 47. The sealing member 47 is an annular body formed of an elastic body such as rubber, and examples thereof include a so-called O-ring and an annular oil seal as an example of the sealing member 47. The sealing member 47 has the same number as the groove 30E of the upper end portion of the lower portion 30B, and is fitted into the groove 30E and surrounds the upper end portion of the lower portion 30B (refer to Fig. 8). In the rotary nozzle 26 completed as shown in Fig. 6, the root portion 26D of the upper end portion 26A covers the upper end portion of the lower portion 30B of the main body portion 26B, and the upper end portion of the lower portion 30B is opened at the opening from the lower side Z2 to the upper end portion 26A. The state of 26C (refer to Figure 8). The upper end portion of the rib 30F is contacted from the upper side Z1 by the root portion 26D, and the upper end portion 26A is positioned in the vertical direction Z with respect to the main body portion 26B. The sealing member 47 is compressed between the upper end portion of the lower portion 30B and the inner peripheral surface of the root portion 26D, and closes the gap between the lower portion 30B, that is, the main body portion 26B and the upper end portion 26A (see Fig. 8). The sealing member 47 in a state of being compressed in this manner connects the upper end portion 26A and the main body portion 26B so as not to accidentally disengage the upper end portion 26A from the main body portion 26B during the rotation of the rotary nozzle 26.

The lower end portion 30C of the lower portion 30B is also the lower end portion 26I of the main body portion 26B. A sliding portion 26J is integrally provided at a position at the lower end of the outer peripheral surface of the cylindrical lower end portion 26I. Referring also to Fig. 10 which is a cross-sectional view of the FF of Fig. 8, the sliding portion 26J is formed in an annular shape surrounding the longitudinal axis J, and the contour 26K of the sliding portion 26J in a plan view is formed to surround the longitudinal axis J and from the lower end portion. The outer circumference of the 26I faces the polygon extending radially outward R1 (here, a regular octagon).

Referring to Fig. 8, a support portion 48 is provided in the second bottom surface portion 12B of the bottom surface portion 12 of the storage chamber 11. The support portion 48 is formed in a bottomed cylindrical shape having a central axis that coincides with the vertical axis J, is fixed to the second bottom surface portion 12B, and is disposed to protrude from the second bottom surface portion 12B toward the upper side Z1. The insertion hole 48A as the inner space of the support portion 48 is open to the upper side Z1. A through hole 48C that is continuous with the second flow path 33 extending from the pump 29 is formed at the bottom portion 48B of the support portion 48.

The lower end portion 26I of the main body portion 26B is inserted into the insertion hole 48A of the support portion 48 from the upper side Z1. Thereby, the entire rotary nozzle 26 including the main body portion 26B is rotatably supported by the support portion 48 of the bottom surface portion 12 about the vertical axis J. In this state, the upper end of the support portion 48 is in contact with the end portion of the horizontal inner side R2 of each horizontal nozzle 31 of the main body portion 26B from the lower side Z2, and the lower end portion 26I is in contact with the bottom portion 48B of the support portion 48 from the upper side Z1. The entire rotary nozzle 26 is positioned in the up and down direction Z. The internal space of the lower end portion 26I is in a state of being in contact with the through hole 48C of the bottom portion 48B of the support portion 48 from the upper side Z1 and communicating with the inside of the second flow path 33 via the through hole 48C. The sliding portion 26J having the polygonal contour 26K provided at the lower end portion 26I is in contact with the inner peripheral surface 48D of the insertion hole 48A, that is, the inner peripheral surface of the support portion 48 at a plurality of corner portions thereof (see FIG. 10).

As described above, when the shoe S is held in the reversing posture by the holding portion 16 in the storage chamber 11, the first ejection openings 20D disposed above the upper end portion 26A of the rotary nozzle 26 are disposed on the sole SZ of the shoe S. High position. Each of the second injection ports 20E disposed at a position lower than the first injection port 20D at the upper end portion 26A may be disposed at a position higher than the sole SZ, may be disposed at the same height position as the sole SZ, or may be disposed at a sole SZ low position. In FIG. 8, the second injection port 20E is disposed at a position lower than the sole SZ.

Each of the first injection ports 20D is set to face the obliquely lower side, and each of the second injection ports 20E is set to face the horizontal direction or the obliquely lower side. Therefore, in the cleaning operation, the cleaning liquid that has flowed into the tower nozzle 30 of the rotary nozzle 26 and reaches the upper end portion 26A is ejected obliquely downward from the first injection port 20D and is poured on the sole SZ (refer to the thick broken arrow), from the second The injection port 20E is sprayed in the horizontal direction or obliquely downward and is deposited on the side portion SS (the side portion SS on the tower nozzle 30 side) of the shoe S (refer to the thick solid arrow). That is, the first injection port 20D of the plurality of injection ports 20A provided at the upper end portion 26A on the upper side Z1 of the sole SZ is for the sole SZ, and the second injection port 20E at the lower side Z2 of the sole SZ is the side portion. Used by SS. The shoe sole SZ can be cleaned by the washing liquid sprayed from the first injection port 20D, and the side portion SS can be washed by the washing liquid sprayed from the second injection port 20E.

Further, in the washing operation, the rotary nozzle 26 is rotated. Then, in the sliding portion 26J having the polygonal contour 26K in a plan view, only the corner portion is wiped with the rotation of the rotary nozzle 26 to the inner peripheral portion 48D of the insertion hole 48A, specifically, in the circumferential direction T and The inner peripheral portion 48D is in line contact (see Fig. 10). Thereby, the portion of the sliding portion 26J that slides the inner peripheral portion 48D of the insertion hole 48A can be suppressed to be small. Therefore, since the abrasion of the sliding portion 26J is reduced and the life of the sliding portion 26J is extended, the frequency of the maintenance sliding portion 26J is lowered. Therefore, it is possible to improve maintenance.

In the upper end portion 26A of the rotary nozzle 26, the injection port 20A provided in the first divided body 26F is disposed asymmetrically with the injection port 20A provided in the second divided body 26G. With this configuration, the momentum of the cleaning liquid injected from the injection port 20A of the first divided body 26F and the momentum of the cleaning liquid injected from the injection port 20A of the second divided body 26G can be unbalanced, so that the rotary nozzle 26 is rotating. In the case of tilting, the posture of the rotary nozzle 26 can be naturally corrected by the difference in momentum of these cleaning liquids, so that the inclination of the rotary nozzle 26 can be eliminated. Therefore, it is possible to prevent the rotation of the rotary nozzle 26 from being stagnant due to the inclination of the rotary nozzle 26.

The rotary nozzle 26 can be separated into an upper end portion 26A and a main body portion 26B. Therefore, when the upper end portion 26A is clogging a foreign object or the like, and the upper end portion 26A is to be maintained, even if the entire rotary nozzle 26 is not detached from the storage chamber 11, as shown in FIGS. 7A and 7B, only the unloading is performed. The upper end portion 26A can also maintain the upper end portion 26A up to the inside thereof and remove the foreign matter in the upper end portion 26A. Therefore, it is possible to improve maintenance.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the claims.

For example, in the above-described embodiment, the shoe washing apparatus 1 is used in a base (not shown) of the washing machine, but may be embedded in the washing machine itself. In these cases, the control unit 40 of the shoe washing apparatus 1 may also pass The control unit of the washing machine receives an instruction to perform a washing operation. Of course, the shoe washing apparatus 1 can be separately present without being embedded in the base of the washing machine or the washing machine. In this case, the frame 2 can also be omitted, so that the main body 3 cannot slide.
