Abstract

PROBLEM TO BE SOLVED: To provide a shoe drying device which can readily dry skiing shoes and the like. SOLUTION: In a shoe drying device 112 which is inserted in a skiing shoe, an air passage which allows a toe portion 126 to communicate with a shin portion 130 is formed. Upon driving a motor mounted in a main body 114, an air sucked from an outside is heated by an electric heater 182. This heated air is blown off through apertures 200, 202, 230 which are formed in the toe portion 126, a bottom portion 127 and a heel portion 128 respectively to the inside of the shoe. The air of high humidity generated after such a heating operation is flows through a gap defined between an outer face of a leg portion and a shin portion 130 and an inner face of the shoe and is discharged from the opening of the shoe. In this manner, an air flow can be generated in the skiing shoe so that the high humidity air in the shoe is prevented from dwelling inside of the shoe thus enhancing the drying operation. Furthermore, the air flow which flows along the inside surface of the shoe can be generated with a relatively small amount of air.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe dryer for drying ski boots, boots, boots, etc., and more particularly to facilitating a drying operation.

[0002]

2. Description of the Related Art Shoe dryers for drying shoes when they become wet are already known. Typical of these are those used to dry ski shoes at ski resort hotels and ski equipment rental shops. For example, as shown in FIG. 15, a main body portion 400 connected to a blower (not shown)
A large number of blowing hoses 402 are extended from the
The tip end of each blowing hose 402 is inserted into the ski boot 404 for use. When the blower connected to the main body 400 is operated, the blowout hose 402 passes through the main body 400.
The air is blown into the ski boot 404 from the air, and the inside of the ski boot 404 is dried.

As a simple one, as shown in FIG. 16, one in which ski shoes are dried one by one is also known. An outlet pipe 502 is projected upward from the main body portion 500, and the ski shoe 50 is attached to the outlet pipe 502.
4 is used upside down. A blower is arranged in the main body 500, and an electric heater may be arranged as necessary.

[0004]

Although the shoes can be dried by any of the above-described shoe dryers, there is a problem that the drying operation is troublesome. Since the one shown in FIG. 15 has a large-sized main body portion 400, it is necessary to carry the ski shoe 404 to a place having a shoe dryer and dry it, and to replace it with another ski shoe when drying is completed. . Also,
16 has a relatively small body portion 500, it is relatively easy to carry the shoe dryer itself to a desired place for use, but nevertheless, the body portion 500 is still small.
Ski boots 504 on the outlet pipe 502 protruding upward from the
Since it is upside down, it is still large and difficult to carry and store, and it is not possible to dry ski shoes while they are stored in the shelves. In the above, the explanation was given by taking the case of drying ski shoes as an example, but it is not only ski shoes that need to be dried, but not only skating shoes, snow boots and other shoes that are particularly easily wet, but also general boots and short shoes are wet and dry. It may be necessary to let In particular, it is necessary to use a shoe drying tool because a shoe having a cloth for cold protection or felt attached to the inside of the shoe does not easily dry naturally once it gets wet.

The present invention has been made in view of the above circumstances, and an object of a first invention according to claim 1 is to facilitate the handling of the shoe dryer itself and facilitate the drying operation. . A second object of the present invention according to claim 2 is to obtain a shoe dryer having low noise during use.
A third object of the present invention is to provide a shoe dryer that can efficiently dry the inside of a shoe. An object of a fourth invention according to claim 4 is to obtain a shoe dryer which can dry shoes in a short time, and an object of the fifth invention according to claim 5 is to dry not only boots but also short shoes. In addition, it is to obtain a shoe dryer which does not require a large space when drying or storing short shoes.

Means for Solving the Problems, Functions and Effects of the Invention
In the first aspect of the present invention, in the first invention, one end portion having an opening is inserted into a shoe, and the other end portion having another opening is provided in a tubular main body protruding outward from the shoe. The solution is to provide an electric blower that blows air from one of the openings to the other.

The electric blower can blow air from the end protruding outward from the shoe toward the end inserted into the shoe, or can blow air in the opposite direction. In the former case, the air sucked from the outside is blown out through the main body of the shoe dryer at the back of the shoe and is discharged from the opening of the shoe to the outside, thereby causing the air flow inside the shoe. In the latter case, the air inside the shoe is sucked in by the shoe dryer and is discharged to the outside through the inside of the main body. Instead, the outside air is sucked in through the opening of the shoe, so that the air flows inside the shoe. Is caused. In this way, when the air flow is generated inside the shoe, high-humidity air does not stay inside the shoe, and the drying is promoted. However, in general, blowing the air from the end inserted into the shoe makes it easier to create a flow of air along the entire inner surface of the shoe than inhaling the air, so the former is desirable,
The former is also desirable in that an electric heater and a filter, which will be described later, can be provided.

The shoe drying tool is a small one in which an electric blower is incorporated in a tubular body, and since it can be used by inserting it into one shoe one by one, it can be easily handled and stored in a shelf. It is also possible to insert it into the shoe as it is and use it.
Further, as compared with a conventional shoe dryer having a main body and an outlet pipe, it is simpler because it does not have a main body, and can be manufactured at low cost. Furthermore, if only one gets wet, it is possible to dry only the wet one,
In addition, one shoe can be dried with one shoe dryer by sequentially inserting and using each pair of shoes.

In the second aspect of the invention, the above problem is solved by disposing the electric blower in the portion of the main body to be inserted into the shoe. The electric blower emits noise during operation, but if it is located inside the shoe, the shoe can function as a sound insulation member and reduce noise.

In a third aspect of the present invention, the above object is to provide a foot portion having a shape substantially similar to the internal space from the toe portion of the shoe to the heel portion at one end portion of the main body to be inserted into the shoe, and the foot portion thereof. This is solved by providing a plurality of openings in the. When the foot portion is provided and the opening is provided in the foot portion, the air blown from the opening or the air sucked into the opening flows through the gap between the outer surface of the foot portion and the inner surface of the shoe. Therefore, an air flow along the inner surface of the shoe can be effectively generated with a relatively small amount of air, and energy can be saved. Further, by providing a plurality of openings in the foot portion, it becomes easy to generate a substantially uniform air flow in the gap between the outer surface of the foot portion and the inner surface of the shoe, and from this point also, the efficiency of drying is improved. be able to.

In a fourth aspect of the present invention, the problem is that the electric blower extends from an intake port, which is an end-side opening that projects to the outside of the shoe, to an outlet port, which is an end-side opening that is inserted into the shoe. The problem is solved by providing an inner cylinder extending along the air passage in at least a part of the air passage in the main body and providing an electric heater in the inner cylinder. The air taken in by the electric blower from the end portion protruding to the outside of the shoe is heated by the electric heater and then blown out into the shoe. When air also flows in the inner cylinder, part of the heat generated by the electric heater is directly transferred to the air, and the rest is transferred to the inner cylinder as radiant heat, and is diffused to a wide portion of the inner cylinder by conduction. Then, it is transmitted from the large surface of the inner cylinder to the air by conduction. When air does not flow in the inner cylinder, all heat is once transferred to the inner cylinder,
Then it is transmitted to the air. In any case, since the air flow is in contact with the inner cylinder for a long time, it is heated well. When the air is heated, the temperature rises and the humidity decreases, so that the inner surface of the shoe can be dried quickly.

In the fifth invention, the above problem is solved by making the length of the main body adjustable. As will be described in detail later, the body can be adjusted in length by attaching and detaching auxiliary members such as extension pipes and by expanding and contracting the tubular portion. Since it can be shortened for use during drying, it does not need a large space unnecessarily. Therefore, it is possible to dry the boots and boots while they are stored in the appropriate shelves. If the body is shortened, the shoe dryer itself can be stored easily.

For example, when the inner layer portion 104 of the ski shoe 100 is thin or has little wetting, the heater control switch 194 is turned off and the motor control switch 192 is turned on.
When turned on, it can be sufficiently dried only by blowing air. Further, in a ski shoe rental shop, when it is sufficient to dry the shoes within about 12 hours until the next day, when the indoor air temperature is high and the humidity is low, the electric heater 182 is turned off to dry the shoes. It is sufficient to use the tool 112.

When the ski shoes 100 get wet very badly, the motor control switch 192 can be strongly switched to increase the air flow rate. At the same time, by adjusting the strength of the heater control switch 194, the drying speed of the ski shoe 100 can be adjusted. In this way, the motor 140 and the electric heater 182 can be adjusted according to how the shoes get wet, so that when one of the ski shoes 100 gets extremely wet, or when a large number of shoes 100 are dried at the same time. In some cases, for example, all shoes can be dried at about the same time.

The lids 204, 206 and 238 are the ski shoes 1
00 is opened and closed depending on which part of the inner layer portion 104 of 00 is wet. When the opening 200 of the toe portion 126 is opened, air can be blown to the innermost portion of the inner layer portion 104, so that an air flow can be generated in the entire internal space of the ski shoe 100. Also, ski shoes 10
It is easy for moisture that has dropped due to its own weight to collect on the bottom portion 107 of 0, but if the opening 202 of the bottom portion 127 is opened,
This part can be dried intensively. further,
Since the heel 108 of the ski shoe 100 is bent and retracted, air is likely to stay therein.
When 30 is opened, air flow can be positively generated in the heel portion 108. In this way, the lids 204, 2
By changing the open / closed state of 06 and 238, the flow of air can be changed, and efficient drying can be performed.

The air whose humidity has become high by drying the inner layer portion 104 is discharged to the outside through the space formed between the inner layer portion 104 and the shoe dryer 112. Since the upper end portion of the auxiliary member 116 having the suction port projects outward from the upper end portion of the ski shoe 100, it is possible to prevent the moist air from being sucked into the shoe dryer 112 again. In this way, the air sucked from the outside is the shoe dryer 1
An opening 200 as an outlet through an air passage in 12.
From 202 and 230, the inner layer portion 10 is formed at the back of the ski shoe 100.
4 is blown out toward the outside of the ski shoe 100 and is flowed out through the opening of the ski shoe 100.
Because there is a flow of air inside the ski,
High-humidity air does not stay inside 00, and drying is promoted.

Further, since the air blown out from the openings 200, 202 and 230 flows through the gap between the foot portion 129 and the shin portion 130 and the inner layer portion 104, the inner surface of the ski shoe 100 is relatively small amount of air. It is possible to effectively generate an air flow along the path and save energy. Further, since the toe portion 126, the bottom portion 127, and the heel portion 128 are provided with openings, respectively, the foot portion 12
It becomes easy to generate a substantially uniform air flow in the gap between the outer surface of 9 and the inner surface of the ski shoe 100, and the efficiency of drying can be improved.

In this embodiment, since the motor 140, the electric heater 182 and the filter 252 can be incorporated in the shoe dryer 112, the entire dryer can be downsized and can be manufactured at low cost. Moreover, since one ski shoe 100 can be inserted and used one by one,
Easy to handle. Furthermore, if only one shoe gets wet, it is possible to dry only that wet one,
In addition, one shoe can be dried with one drying tool by sequentially inserting and using each pair of shoes. Moreover, since the motor 140 is arranged in the main body of the shoe dryer 112 and the main body is inserted into the ski shoe 100, the main body and the ski shoe 100 function as a sound insulation member, and noise generated when the motor 140 is operated. Can be reduced.

In the present embodiment, the motor 140 is a DC motor, and the DC motor can be easily made smaller than the AC motor. Many small electric blowers using the DC motor are commercially available. Therefore, it is possible to select and use an appropriate one from them. Further, the DC motor can easily control the rotation speed, and can easily control the air flow rate. In particular, many commercially available small electric blowers use a DC motor having a rating of 24 V or less as in the present embodiment, and a DC of 24 V or less is safe even in the event of an electrical leakage, and a DC power source for an automobile. It is also possible to use to allow the shoes to dry.

In this embodiment, the inner cylinder 180 is connected to the main body 114 at a portion near one end farthest from the portion where the electric heater 182 is arranged. Wherever the electric heater 182 is arranged in the inner cylinder, there is one end farthest from the electric heater 182. Since the temperature near the one end is the lowest, the amount of heat conducted to the main body of the shoe dryer 112 via the connecting portion 188 can be minimized, and the temperature of the main body can be prevented from increasing. A low temperature is desirable because the body of the shoe dryer 112 may directly contact the inner surface of the ski shoe 100.
Further, since the temperature rise of the main body is small, it becomes possible to manufacture the main body from a synthetic resin having low heat resistance, and the shoe dryer 11
2 can reduce the manufacturing cost.

In this embodiment, the length of the shoe dryer 112 can be adjusted by attaching and detaching the auxiliary member 116 to and from the main member 114. When the boots are dried, the auxiliary member 116 is attached to lengthen the shoe dryer 112, and when the boots are dried, the auxiliary member 116 is removed to remove the shoe dryer 112.
Since it can be shortened, it does not need a large space unnecessarily. Therefore, it is possible to dry the boots and boots while they are stored in the respective shelves.
Also, if the body of the shoe dryer 112 is shortened, the shoe dryer 11
The storage of 2 itself becomes easy.

In this embodiment, the taper fitting portion 260 of the main member 114 is fitted to the taper fitting portion 26 of the auxiliary member 116.
Although the length of the shoe drying tool 112 can be adjusted by tightening and fitting No. 4, the auxiliary screw and the main member are formed with a female screw on one side and a male screw on the other side, and these screws are screwed together. It is also possible to detachably connect the auxiliary member to the main member. Further, as shown in FIG. 12, each of the main member 268 and the auxiliary members 270, 272 can be telescopically fitted in a telescopic manner.
With this configuration, since the auxiliary members 270 and 272 are always attached to the main member 268, there is no fear of loss and easy storage. A tight fit between the main member and one of the auxiliary members,
It is also possible to connect the auxiliary members with each other by screwing or the like so that the auxiliary members can expand and contract.

In the above embodiment, the openings 200, 2
02 and 230 are the toe part 126, the bottom part 127, and the heel part 128.
It was formed in 3 places, but any of them 2
It is also possible to form the openings at one place or only one place. It is also possible to form the openings at three or more locations. The shape and number of openings can be changed arbitrarily,
It is not essential to be able to open and close the opening.

Inner cylinder 180 provided with electric heater 182
A projection for heat dissipation on at least one of the inner and outer peripheral surfaces of
For example, a radiation fin extending in the axial direction may be provided. By doing so, the contact area between the inner cylinder and the air flow is increased, and the heat transfer efficiency can be improved. Further, in the above-described embodiment, the passage through which air flows is formed between the inner cylinder 180 and the electric heater 182, but it is also possible to adopt a structure in which air does not flow inside the inner cylinder. In this case, all the heat generated by the electric heater is once transferred to the inner cylinder and then to the air.

In the present embodiment, the motor control switch 192 and the heater control switch 194 can be switched between two levels of strength, but the strength can be continuously adjusted by enabling switching in two or more levels. You can also do it.

It is not essential to use a DC motor for the electric blower, and it is also possible to use an AC motor. Electric heaters are not always necessary, and if the shoes can be dried sufficiently by blowing air, or if you need to dry the shoes within about 12 hours until the next day at a ski or skate rental shop, the indoor air In the case where the temperature is high and the humidity is low, it is possible to use a shoe dryer having only an electric blower and no electric heater.

In the present embodiment, the toe portion 126 and the bottom portion 127 are formed on the first member 118, and the second member 12 is formed.
0 has a heel portion 128 formed therein, and a toe portion 129 is formed by the toe portion 126, the bottom portion 127 and the heel portion 128. However, as shown in FIG.
