Description

  The present invention relates to a washing apparatus for washing shoes such as leather shoes, and in particular, a stationary laundry tub having a non-rotating non-oscillating structure and water in a stationary laundry tub having a non-rotating non-oscillating structure. The surface of the shoe is brazed by providing a jet-type water flow generating device that induces the flow of turbulent mixing and stirring, etc. to generate mixing and stirring of detergent and water, and the relative flow of washing water and washing shoes. The present invention relates to a shoe washing apparatus that performs washing without any problems.

[Background of the invention]
Washing and cleaning footwear has always been done as a domestic task. However, since entering the modern consumer society, it is doubtful how much interest urban residents have had in cleaning shoes (especially washing ), and traditional households that wash school shoes for children and students. In addition to internal work, intensive work at workplaces (for example, washing many rubber boots at civil engineering workshops, fishery processing factories, etc., washing team members' sports shoes (sneakers) at the same time, etc.) ) It seems that it was just enough to see similar examples. In addition, these are thought to be limited to manual work with a used toothbrush or the like, or dark cloud washing using a normal automatic washing machine and a normal detergent.
Regarding the cleaning / regeneration of leather shoes, conventionally, it has been limited to small-scale work such as street shoe polishing or wiping treatment by a shoe repair company, and the cleaning work itself has not been a business.
Entering the 2000s, on the one hand, the flow of environmental philosophy that emphasizes recycling orientation, and on the other hand, the number of high-class leather shoe holders has gradually increased as part of the upsizing of individuality, and the necessity and interest in the maintenance and care of leather shoes has increased. With the trend of the times, the momentum that can establish a business that integrates cleaning and maintenance work for leather shoes has been fostered.

[Emerging approach to washing leather shoes]
As mentioned above, washing shoes has traditionally been done as a common housework for cloth (canvas) (athletic shoes, sneakers), but for leather shoes, It is said that the washing of leather shoes is intensively carried out as a business by the degree of mud pollution or by the hands of a trader who specializes in leather shoes repair at the stage of shoe repair, which was sometimes done individually and on a small scale There was no idea. The reason for this is that the idea of washing the personal property of leather shoes, including luxury goods, in daily use, even if requested by the owner, was harshly affected. This may be attributed to the fact that there was no simple tool (hardware or hardware) that was equivalent to an automatic washing machine for clothing and linens, including the fact that the technology was not generalized. As mentioned above, the shoe washing machine of this application was backed by the gradual increase in the number of high-class leather shoe holders as part of the individualized upscaling practice, as well as the practice of cleaning and care that comes from the recycling-oriented concept in line with the trend of the times. The rise in interest in the maintenance and care of leather shoes stems from the increased interest in hardware for the consolidation and commercialization of leather shoe cleaning and recycling work.

<< Fig. 7 and Fig. 8: Concept of conventional washing machine for general use (Part 2): (Drum rotation type) >>
Among the conventional machines, there is a track record for business use for many years, and in recent years, a general form is shown in FIG. This system is characterized in that the laundry is dropped from above by the rotation of a drum that rotates about a horizontal axis, and the so-called washing effect is exhibited with a small amount of water. It is said that this method, which can be done with as little water as possible from the land pattern in Europe where warm water must be used for washing because it is hard water, was developed mainly in Europe. The rotation axis of the drum is not necessarily horizontal (FIG. 7) but may have a slight inclination angle (FIG. 8).

<< FIG. 9 and FIG. 10: Water turning state in the tank of the conventional machine by agitator stirring >>
A swirling state of water in a conventional washing tub by agitator agitation is shown in FIGS. FIG. 9 exemplifies agitation and mixing in water, which may be performed for the purpose of sufficiently dissolving the detergent put into the washing tub in advance. In the figure, 301 is the detergent dissolution tank, and 302 is the detergent mixing.

FIG. 10 shows the situation in the tub when shoes are washed with a conventional machine. In the figure, 401 is a washing tub that can rotate around a vertical rotation axis as an example, and 402 is agitating and flowing into the water in the tub. , 403 is the surface of the water in the tank, and 404 is a shoe to be washed. Explain that there is always the fear of wrinkles on the leather surface due to intense rubbing between shoes in a strong swirling flow, collision with metal fittings, etc., so this usage is not possible It is.

By the way, a conventional method used in a mechanical device called a washing machine (for the sake of simplicity, abbreviated as “conventional machine” in the following text) and a difficulty considered when it is used for washing leather shoes, the purpose of the present invention. Is as follows.
a) Conventional machines use mechanical agitators (stirring blades) or rotation of the tank itself to agitate the washing water in the tank, and are not suitable for washing delicate leather products that may cause surface flaws. (Even for general clothing, this method is used for washing delicate objects such as mechanical agitators (stirring blades) and the tank itself, and washing solids and semi-solids that may cause surface flaws) It is already well known that is unsuitable.)
b) In general, it is not possible to achieve the purpose of sufficient dissolution and diffusion of detergent in water by simply putting detergent into rotating water. In particular, in the washing tub, there may be a situation where the shoe is rotating with the undissolved detergent in the toe portion of the shoe, but this does not lead to an increase in cleaning efficiency. (As an example of a general laundry washing tub, washing machines are widely used in the world where granular undissolved detergent is attached to the finished laundry after dehydration due to insufficient dissolution of the detergent in the tub. Even very common now, very often.)
c) Through the above a) and b), a mechanical agitator (stirring blade) or rotation of the tank itself is used to generate the flow in the tank. There is no one that is attached to the leather, and it is easy to give wrinkles to delicate leather products, and it was unsuitable for the purpose of averaging the spots such as detergent dissolution and cleaning effects.

  In view of the above-mentioned problems, the present invention was devised to solve the problems. The object of the present invention is to wash the surface of the shoe without scuffing and to provide a cleaning power and a cleaning effect. Providing a shoe washing machine that can eliminate the restriction of the shape of the washing tank, eliminate the need for complicated structures and mechanisms such as a rotating device, and make the washing tank more compact and lower in cost. There is to do.

  In order to achieve the above object, the device of claim 1 is a washing apparatus used for washing shoes using water and a detergent, and is a non-rotating non-oscillating type equipped with a water supply pipe and a drain pipe. A fixed washing tub composed of a structure, and a mixture of detergent and water mixed with stirring and washing water by inducing a flow such as turbulent mixing and stirring in the water in the fixed washing tub composed of a non-rotating and non-oscillating structure. The apparatus comprises at least a jet-type water flow generator that generates a relative flow with the laundry shoe.

  Further, the invention of claim 2 is a washing apparatus used for washing shoes using water and a detergent, and is a fixed type washing having a non-rotating non-oscillating structure equipped with a water supply pipe and a drain pipe. Inducing the flow of turbulent mixing / stirring etc. in the water in the tank and the stationary washing tub with a non-rotating non-oscillating structure to induce mixing / stirring of detergent and water, and relative flow of washing water and washing shoes A pre-treatment tank for removing coarse dust attached to shoes before washing in the washing tub, a rinsing tank for rinsing shoes after washing in the washing tub, and a rinsing tank It comprises means in which a finishing tub for allowing the finishing agent to permeate the shoes after being rinsed in the tub.

  Here, as a preferable aspect, in the shoe washing apparatus according to claim 2, the pretreatment tub, the washing tub, the rinsing tub, and the finishing tub are arranged in a linear direction.

  Here, as a preferable aspect, in the shoe washing apparatus according to claim 2, the pretreatment tub, the washing tub, the rinsing tub, and the finishing tub are arranged in the circumferential direction.

  Here, as a preferred embodiment, the shoe washing apparatus according to any one of claims 1 to 4 includes an ultrasonic vibrator that generates high-frequency vibrations for the purpose of enhancing the dirt exudation and washing effect. Located on the wall.

  Here, as a preferable aspect, the shoe washing apparatus according to any one of claims 1 to 5 is provided with a shoe dryer.

Here, as a preferred embodiment, the shoe washing apparatus according to claim 2 or 3 is provided with a second finishing tub for finishing the surface of the leather shoes by performing a treatment with a leather retaining agent on the surface of the shoe next to the finishing tub. It has been.

As is apparent from the above description, the shoe washing apparatus according to the first and second aspects of the present invention has the following practically beneficial effects.
a) Do not use a mechanical agitator (stirring blade) or the method of rotating the tank itself to agitate the washing water in the tank. Instead, a turbulent mixing circulation flow by suction and discharge is generated in a fixed water tank using the principle of high-speed jet turbulent mixing and fluid stirring, and this is used for stirring in the washing tank. Thereby, the effect of washing water stirring can be maximized within a relatively small volume range. In other words, instead of moving the washing shoes relatively rapidly in the tub, that is, stirring them, by promoting the replacement and circulation of water, it is possible to stop the water mass from remaining undissolved in the shoes. Retention can be eliminated. That is, the effect of washing water agitation can be maximized without using an in-tank agitation blade (mechanical rotation agitator) that causes wrinkles to be applied to washing shoes.
b) Simply putting the detergent into the rotating water will not achieve the objective of sufficient dissolution and diffusion of the detergent in the water. Instead, suction is performed using the principle of high-speed jet turbulent mixing and fluidized stirring.・ Generates a turbulent mixing circulating flow by discharge, thereby maximizing the dissolution of the detergent in water and spreading it uniformly in the tank to achieve sufficient diffusion of the detergent in the water and enhancing the cleaning effect. Can be achieved.
c) Exudation of contaminants using mechanical agitators (stirring blades) in tanks in conventional washing machines that occupy the mainstream, rotation and rotation mechanisms of the tanks themselves, and ultrasonic waves added as necessary The promotion of divergence is closely related to the shape and dimensions of the washing tub, and was associated with restrictions such as the cylindrical shape of the tub. The restriction on the shape of the tank is largely eliminated, and a cleaning tank having a desired size and shape can be realized as necessary. As a result, the cleaning power and the cleaning effect can be made uniform in the tank and the function can be improved. That is, the restriction of the shape of the cleaning tank is largely eliminated, a complicated structure / mechanism such as a rotating device can be eliminated, and the cleaning tank can be made compact and low in cost.

  As described above, the present invention is contrary to the fact that a general washing machine and a washing machine use a movable mechanism such as a stirring blade and a rotating drum and a movable tank to flow and circulate the washing water in the tank. No moving mechanism is used. Instead, jet flow promotion is used here to promote mixing and dissolution of water and detergent, and contact and agitation between the melted detergent and laundry based on the principle of turbulent mixing. This eliminates the need for wear, eliminates worn parts, and greatly improves durability. As a result, compared to conventional washing methods, the efficiency of detergent use is improved, and the washing efficiency suitable for high-quality leather products (shoes) can be improved, so that the overall efficiency of a washing machine suitable for the same is significantly improved. Has increased. In addition, it constitutes a single equipment that can demonstrate the above series of actions and effects in a form that does not cause any fear of wrinkling high-grade leather products (local turbulent mixing and gentle overall flow stirring). Is.

  Moreover, according to the shoe washing apparatus according to the invention of claim 2, in addition to the above-described effect, the pretreatment tank can remove the coarse dust attached to the shoes before washing in the washing tub. It is possible to prevent the washing tub from becoming dirty. In addition, the detergent attached to the shoe in the washing tub can be reliably rinsed and removed by the rinsing tub. Furthermore, the finishing agent can be infiltrated into the shoes washed by the finishing tub so that the shoes after washing can be restored to the original state or improved to a higher state.

  Moreover, when the pretreatment tank, the washing tank, the rinsing tank, and the finishing tank are arranged in a linear direction as in claim 3, the movement is made in accordance with the shoe washing process by moving along the linear direction. Can be washed.

  Further, when the pretreatment tub, the washing tub, the rinsing tub, and the finishing tub are arranged in the circumferential direction as in claim 4, the shoe is moved along the circumferential direction to follow the shoe washing process. It can definitely be washed.

  Further, in the case where an ultrasonic vibrator that generates high-frequency vibration is provided on the washing tub wall for the purpose of enhancing the dirt exudation and cleaning effect, the water in the washing tub is disturbed. The flow performance of the jet-type water flow generator that induces the flow of mixing, stirring, etc. to induce the mixing and stirring of detergent and water, and the relative flow of washing water and washing shoes, synergistically improves The cleaning effect can be further enhanced.

  Further, when a shoe dryer is provided as in claim 6, wet shoes after washing can be dried earlier than natural drying, and the washing time of shoes can be shortened. be able to.

Moreover, when the 2nd finishing tank for finishing by processing leather preservation fats and oils etc. on the surface of leather shoes is provided next to a finishing tank like Claim 7, the fats and oils after washing are removed It is possible to restore the gloss of the surface of the leather shoes by re-penetrating the leather retaining oil or the like into the surface of the leather shoes that has been reduced or decreased.

  Hereinafter, the present invention will be described more specifically based on the best mode for carrying out the invention described in the drawings.

[Best Mode-1]
Here, FIG. 1A is a schematic overall front view of a shoe washing apparatus, FIG. 1B is a schematic side sectional view of a washing tub of the shoe washing apparatus, and FIG. 2 is a sectional view of a jet-type water flow generator.

  In FIG. 1, the shoe washing apparatus includes a pretreatment tank 1, a washing tub 2 with a jet-type water flow generator 8, a rinsing tub 3, and a finishing tub 4, and can be washed without scratching the surface of the shoe. Features that can enhance the cleaning power and cleaning effect, greatly eliminate restrictions on the shape of the cleaning tank, eliminate the need for complicated structures and mechanisms such as a rotating device, and achieve a compact cleaning tank and low cost. Have.

  As shown in FIG. 1A, the pretreatment tank 1, the washing tank 2, the rinsing tank 3 and the finishing tank 4 constituting the shoe washing apparatus are arranged in this order in a linear direction. That is, in FIG. 1A, the pretreatment tank 1 is straight on the right end, the washing tank 2 is on the left side of the washing tank, the rinsing tank 3 is on the left side of the washing tub 2, and the finishing tank 4 is on the left side of the rinsing tank 3 on the left side. Arranged in the direction. Each aquarium is completely partitioned so that water and liquid in each aquarium do not mix. Each water tank has a square shape when viewed from above.

  The pretreatment tank 1 is a water tank provided to remove coarse dust attached to the shoes before washing in the washing tank 2, and the coarsely attached to the shoes in this water tank before being washed in the washing tank 2. Garbage is washed away. Thereby, it can prevent that the inside of the washing tub 2 of the next process gets dirty with the coarse dust adhering to shoes.

  The washing tub 2 uses a jet-type water flow generator 8 arranged in the tub to induce a flow such as turbulent mixing / stirring in the water in the tub, thereby mixing and stirring the detergent and water, and washing water. This is a tank for washing shoes by generating a relative flow between the shoes and the washing shoes. The jet-type water flow generator 8 is disposed on the lower side of the washing tub 2.

  Since the washing tub 2 is washed using the jet-type water flow generator 8, it has a fixed structure rather than a movable mechanism such as a rotating tub or a rocking tub as in the conventional apparatus. The washing tub 2 can eliminate the need for a rotating tub, a stirring wing or a rotating oscillating mechanism for the oscillating tub as in the conventional apparatus, and thus has an advantage of increasing the degree of freedom and compactness in its shape and structure. .

  The jet-type water flow generator 8 is a device that induces a flow such as turbulent mixing / stirring in water in a stationary washing tub to generate a mixed stirring of detergent and water, and a relative flow of cleaning water and washing shoes. It is. Unlike the conventional apparatus, the washing tub 2 equipped with the jet-type water flow generator 8 does not use a movable mechanism such as a stirring blade or a rotating drum, or a movable tub, and therefore does not wear shoes during washing.

  The jet-type water flow generator 8 generates a turbulent mixing circulating flow by suction and discharge using the principle of high-speed jet turbulent mixing and fluidized stirring, thereby maximizing the dissolution of detergent in water. The purpose is to allow the detergent to sufficiently dissolve and disperse in water and enhance the cleaning effect so as to be evenly distributed in the tank. On the other hand, it was not possible to achieve the purpose of sufficient dissolution and diffusion of the detergent in the water only by introducing the detergent into the water rotated by the rotary stirring blade of the conventional apparatus. It is up to you to achieve this.

  As shown in the figure, the jet-type water flow generator 8 includes an outer cylinder 8c having an upstream end 8a and a downstream end 8b opened in the washing tub 2, and an inlet 8d and an outlet 8e opened at both ends, respectively. A cylindrical body comprising a cylindrical body 8f mounted in the outer cylinder 8c toward the upstream end 8a and the downstream end 8b, and a jet nozzle 8g opened in the outlet 8e direction and mounted in the cylindrical body 8f. A jet pump is formed by 8f and the jet nozzle 8g.

  The jet-type water flow generator 8 generates a jet pump water flow that flows in from the inlet 8d and flows out to the outlet 8e by the water of the driving fluid supplied from the outside to the jet nozzle 8g through the supply pipe 8h. A water flow in the outer cylinder 8c that flows in from the flow 8a and flows out to the downstream end 8b is generated and sucked and discharged into the washing tub 2 by the water flow in the outer cylinder 8c using the principle of high-speed jet turbulent mixing and fluidized stirring. The generated turbulent mixing circulatory flow generates a water flow.

  The rinsing tank 3 is a water tank provided for rinsing the shoes after washing in the washing tank 2 to completely remove the detergent, and the detergent attached to the shoes in the water tank during washing in the washing tank 2 is washed. To be removed. Thereby, while being able to prevent a part of detergent from adhering to the shoes after washing, it can prevent that a part of detergent is mixed in the finishing tank 4 of the next process.

  For this reason, the water spray pipe device 9 which produces | generates an upward one way flow with the water which blows off from a hole is arrange | positioned at the bottom part in the rinsing tank 3. FIG. The detergent adhering to the shoes in the washing tub 2 during washing is washed away by the water blown out from the water spray device 9.

  The finishing tank 4 is a water tank provided to allow the finishing agent to permeate into the shoes after being rinsed in the rinsing tank 3, and the finished shoes are infiltrated into the original state by allowing the finishing agent to permeate the washed shoes. It can be raised to a revival or better. As the finishing agent that penetrates into the shoes in the finishing tank 4, a chemical effective for protecting and preserving leather is used.

  By allowing the finishing agent to permeate the shoe in the finishing tank 4, the surface state of the leather shoe can be maintained well and the hygiene can be improved.

  The water supply pipe 5 is a pipeline that supplies cleaning water to the water tanks of the pretreatment tank 1, the washing tank 2, the rinsing tank 3, and the finishing tank 4 as necessary, and is extended to the upper side of each water tank. Yes. In the middle of the water supply pipe 5 extending to the upper side of each water tank, a water supply faucet 6 attached upward and having a tip downward is attached.

  The water supply faucet 6 is attached to the boundary between the pretreatment tub 1 and the washing tub 2 and the boundary between the rinsing tub 3 and the finishing tub 4, and the water supply faucet 6 is located on both sides of the boundary. The structure of the faucet can be changed freely. Each water supply faucet 6 is provided with a stop cock 7 that can discharge or stop the washing water.

  The drainage drain pipes 10 are pipes for discharging water from the water tanks of the pretreatment tank 1, the washing tank 2, the rinsing tank 3, and the finishing tank 4, and are respectively attached downward to the lower side of each water tank. Each drainage drain pipe 10 has an upper end connected to the bottom of each water tank, and a lower end connected to a drain main pipe 14 disposed below each water tank in a straight line direction of each water tank. ing. The water in each water tank is drained into a common drain main pipe 14 through each drain drain pipe 10.

  The drive water pipe 11a is a pipe for sending pressurized water from the drive water pump 11 to the jet-type water flow generator 8 arranged in the washing tub 2 and the water spray pipe device 9 arranged in the rinse tub 3, respectively. The upstream end of the supply pipe 8h of the water flow generator 8 is connected, and the upstream end of the water spray apparatus 9 is connected. The pressurized water supplied through the drive water pipe 11a is branched and sent to the jet-type water flow generator 8 and the sprinkler pipe device 9 respectively.

  The overflow water tray 12 is a bowl provided so that water overflowing from each water tank of the shoe washing apparatus of the present invention, in particular, the washing tank 2 and the rinsing tank 3 does not spread on the floor surface. The overflow water tray 12 is provided on the lower outer side of each of the pretreatment tank 1, the washing tank 2, the rinse tank 3 and the finishing tank 4. The upper end side of the pipe 13 is connected in communication. The overflow drain pipe 13 is a conduit for joining the overflow water receiving water to the drain main pipe 14, and the lower end side thereof is connected to the drain main pipe 14.

  The external drain pipe 15 is a pipe line for draining the waste water joined to the drain main pipe 14 to the outside. After the water in each water tank of the pretreatment tank 1, the washing tank 2, the rinsing tank 3 and the finishing tank 4 joins the drain main pipe 14 through the drain drain pipes 10 and the overflow water trays 12, It is discharged outside by the external drain pipe 15.

Next, a working method based on the configuration of the best mode-1 for carrying out the above device will be described below.
First, before washing various shoes such as leather shoes and work shoes in the washing tub 2, coarse dust adhering to the shoes is removed in the pretreatment tub 1. The stop cock 7 of the water supply faucet 6 is opened, and water is supplied from the water supply faucet 6 into the pretreatment tank 1. Also inject detergent as needed. In this way, water or detergent water for dropping the coarse dust adhering to the shoe surface is put into the pretreatment tank 1, and then the coarse dust adhering to the shoe surface is removed using a scrub brush or a brush. remove. In particular, dirt or the like may be attached to the shoe sole, which is removed with a brush or the like. After removing the coarse dust adhering to the shoes, it is put in the washing tub 2.

  The water supply faucet 6 is rotated toward the washing tub 2, the stop cock 7 is opened, water is poured into the washing tub 2 from the water supply faucet 6, and a necessary amount of detergent is mixed. At the same time, a shoe in which coarse dust has been removed in the pretreatment tank 1 is placed in the washing tub 2. Moreover, the jet-type water flow generator 8 arrange | positioned in the lower part in the washing tub 2 is driven. The jet-type water flow generator 8 is driven by feeding pump pressurized water into the supply pipe 8h through the drive water pipe 11a.

  When pump pressurized water is fed into the supply pipe 8h of the jet-type water flow generator 8, the pump pressurized water is pumped through the supply pipe 8h and supplied to the jet nozzle 8g, and is injected from the jet nozzle 8g toward the outlet 8e of the cylinder 8f. As a result, a jet pump water flow that flows in from the inlet 8d of the cylindrical body 8f and flows out to the outlet 8e is generated. This jet pump water flow generates a water flow in the outer cylinder 8c that flows in from the upstream end 8a and flows out to the downstream end 8b, and the water flow in the outer cylinder 8c causes high-speed jet turbulent mixing and fluid agitation acceleration in the washing tub 2. Using the principle, generate a turbulent mixed circulation flow by suction and discharge.

  In this way, the jet-type water flow generator 8 induces a flow such as turbulent mixing / stirring in the water in the washing tub 2 to mix and stir the detergent and water, and the relative flow between the washing water and the washing shoes. This causes the shoe to be washed.

  In the conventional system shown in FIGS. 6 and 7, the mechanical water agitator (stirring blade) or the rotation of the tank itself is used for stirring the washing water in the tank. Of course, even if the number of clothes (shoes) is reduced, it is obvious that it is not suitable for washing delicate leather products that may cause surface wrinkles. In addition, in the proposed method, a cleaning function can be realized by applying a water flow relative to the shoes.

  Furthermore, it is generally not possible to achieve the purpose of sufficient dissolution and diffusion of the detergent in the water by simply putting the detergent into the rotating water. However, in this proposal, sufficient detergent can be obtained by turbulent mixing of water and detergent in the washing tub 2. By dissolving and diffusing the leather, washing and rinsing effects of leather shoes can be performed more appropriately and with higher functions than conventional machines. In conventional machines, there may be a situation where shoes with a particularly rich detergent are kept rotating in the washing tub 2 as they are. However, in the proposed method, such a situation does not occur, and such difficulties are easily prevented. The

  After washing shoes in the washing tub 2 for a certain period of time using the jet-type water flow generator 8, the shoes are taken out from the washing tub 2 and placed in the adjacent rinsing tub 3. Water is injected into the rinsing tank 3 from the water supply faucet 6 by opening the stop cock 7 of the water supply faucet 6 in advance. In the rinsing tank 3, pump pressurized water pumped through the drive water pipe 11a is spouted upward from the water sprinkling pipe device 9 disposed at the bottom of the rinsing tank 3, and an upward flow is generated. Rinsing with the detergent water adhering to the shoes during washing in the washing tub 2 is performed using this upward flow.

  After sufficiently rinsing in the rinsing tank 3 to remove the detergent water adhering to the shoes, the shoes are taken out from the rinsing tank 3 and placed in the adjacent finishing tank 4. The water stop faucet 6 of the water supply faucet 6 is previously opened in the finishing tank 4 and water is injected from the water supply faucet 6, and the finishing tank 4 is finished with a pigment rejuvenating agent or an antibacterial agent. The agent is mixed.

  By putting the washed shoes in the finishing tank 4 mixed with the finishing agent and allowing the finishing agent to permeate the shoes, the shoe after washing can be restored to its original state or higher. For example, the discoloration of the shoe after washing can be revived by allowing the dye rejuvenating agent to penetrate into the shoe in the finishing tank 4. Further, by allowing the antibacterial agent to permeate, the antibacterial property of the shoe after washing can be enhanced, it is difficult for bacteria to adhere, the generation of a strange odor is prevented, and the hygiene of the shoe can be improved.

Then, after the finish is infiltrated into the shoes, the shoes are taken out from the finishing tank 4 and dried, whereby the washing of the shoes using the shoe washing apparatus of the present invention is completed.

[Best Mode-2]
Here, FIG. 3 is a schematic overall perspective view of the shoe washing apparatus.

  In the best mode-1, the pretreatment tank 1, the washing tank 2, the rinsing tank 3, and the finishing tank 4 constituting the shoe washing apparatus are arranged in a linear direction, but the best mode-2 is different from this. The pretreatment tank 1, the washing tank 2, the rinsing tank 3, and the finishing tank 4 are arranged in the circumferential direction. For this reason, each water tank has a fan shape or a trapezoidal shape when seen from the plane. Correspondingly, the drainage main pipe 14 is also arranged in the circumferential direction. Furthermore, a shoe dryer 17 is newly provided at the upper center of the shoe washing apparatus arranged in the circumferential direction. Since the other configuration is substantially the same as the best mode-1, substantially the same structure is denoted by the same reference numeral, and description of the structure is omitted.

  An annular work table is provided along the circumferential direction on the surrounding floor surface in which the pretreatment tank 1, the washing tank 2, the rinsing tank 3 and the finishing tank 4 constituting the shoe washing apparatus are arranged in the circumferential direction. 16 is provided. The work table 16 is a table on which a standing worker rides. The annular work table 16 may be structured to rotate at a low speed around the central axis of a shoe washing apparatus arranged in the circumferential direction. In addition, it is possible to reduce work labor and improve work efficiency by providing a small number of work seats on the work table 16.

  The shoe dryer 17 is a device for draining a shoe that has been washed and drying it, and is provided at the upper center of the shoe washing device arranged in the circumferential direction.
