DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a shoe dryer, and more particularly to a shoe dryer.
The present invention relates to a shoe dryer that removes water droplets, dust and the like adhering to a shoe surface with pressurized air.

[0002]

2. Description of the Related Art Conventionally, shoe dryers for removing water droplets adhering to the outside of shoes and water seeping into the inside of shoes have been disclosed in JP-A-5-49587 and JP-A-6-181878.
JP-A-7-218127 or JP-A-6-2540
The one disclosed in Japanese Patent Publication No. 33 is known.

[0003] Regarding the shoe dryer disclosed in Japanese Patent Application Laid-Open No. 5-49587, an air (warm air) outlet is inserted into the inside of the shoe to remove water permeated into the inside of the shoe. This configuration is intended to dry the outside of the shoe while removing it.

A shoe dryer disclosed in Japanese Patent Application Laid-Open No. 6-254033 is for drying shoes from the outside of shoes by the heat of a panel heater.

On the other hand, for example, in the case of boots in a food factory, after washing with water from the viewpoint of hygiene, etc., work is carried out from the outside into the factory as it is without changing shoes.

At this time, it is preferable to remove water droplets adhering to the surface of the boots by washing with water in consideration of the environment such as slipperiness and dirt in the factory.

In such a case, since water droplets need to be removed instantaneously, they are generally sucked into a mat or the like near a water washing station. Since it is necessary to remove the attached water droplets, it is necessary to frequently replace the mat, which requires time and effort.

In addition to the above-mentioned food factory, even in the case of safety shoes in a machine factory or the like, when entering the factory from the outside or the like, if dust and the like attached to the surface of the shoes can be removed. It is convenient because it can be moved without changing shoes.

However, in such a shoe dryer, since the shoe is dried from inside or outside the shoe over time, it is necessary to remove and dry water droplets attached to the surface of boots in a food factory. It could not be used for removing dust and the like adhering to the surface of safety shoes in a machine factory.

Therefore, the present applicant has already proposed a shoe dryer that can instantly remove water droplets and the like adhering to the shoe surface and does not give the user any discomfort due to the pressurized air ( Japanese Patent Application No. 2000-336320).

[0011]

Incidentally, in the shoe dryer proposed in Japanese Patent Application No. 2000-336320, a nozzle unit having an outlet for injecting compressed air toward the shoe bottom surface and the shoe side surface is disclosed. Because one is, after drying the surface of one shoe, it is replaced with the other shoe and the surface of the shoe is dried again, so when one shoe is removed from the nozzle unit, the nozzle Water droplets and dust etc. attached to the shoes before drying may remain on the floor around the unit, so depending on the installation environment of the shoe dryer, water droplets and dust etc. may adhere to the shoe bottom again. There was a problem that it would.

In the above configuration, when removing the shoes S, in particular, water droplets and dust adhered to the bottom surface thereof, first, the shoes S are put on the footrests 3 and 4 while wearing the shoes S. At this time, one of the shoes S (left foot with reference to FIG. 5) is the nozzle unit 2
0 is located between the first and third nozzles 21 and 23 (to the extent that the toe is located above the outlet 22d), and the other shoe S (the right foot based on FIG. 5) is one shoe S , That is, it is preferable to place it near each position indicated by the dashed line in FIG.

In this state, the electric blower 12 is driven so that the shoes S are discharged from the outlets 21d to 23d of the nozzle unit 20.
Pressure air is blown toward the bottom and side surfaces on the tip side of the shoe, and one shoe S is moved in parallel while slightly floating from the footrest 3 so that the pressure air blown out from the outlet 22d creates A part of the water droplets or dust is blown off, and the other part of the water droplets travels along the floor surface of the shoe S and is driven into the heel side of the shoe S. Drops of water, dust, etc. attached to the surface are blown away. Then, the shoe S is dried by repeating such a parallel moving operation several times as the case may be.

It is to be noted that, of the pressure air blown out from the outlet 22d, the pressure air flowing upward from a portion deviating from the bottom surface of the shoe S as well as being reflected and bent at the bottom surface (especially a corner portion) of the shoe S. The pressure air going upward (diagonally upward)
The pressure air blown out from each of the outlets 21d and 23d blocks the air without further upward and discomfort and malfunction such that the pressure air is blown on the user's body or water droplets and dust that are blown off adhere to the user's body. Has been resolved.

Further, after the one shoe S is stepped on, the other shoe S is also stepped on. At this time, one shoe S is located between the first and third nozzles 21 and 23 of the nozzle unit 20 (to the extent that the heel comes off from above the outlet 22d).
, And the other shoe S is positioned in front of the first and third nozzles 21 and 23 of the nozzle unit 30 so that the other shoe S is aligned with the one shoe S (to the extent that the toe is positioned above the outlet 22d), that is, It is preferable to place it near each position indicated by the two-dot chain line in FIG. At this time, a footrest 4 on which one shoe S is placed
, That is, water droplets and dust do not adhere to the footrest 3 in front of the nozzle unit 20, so that water droplets adhere again to one shoe S dried by the nozzle unit 20. Has been prevented.

In this state, the electric blower 12 is driven so that the shoes S are discharged from the outlets 21d to 23d of the nozzle unit 30.
Pressure air is blown out toward the bottom and side surfaces on the tip side of the shoe, and the other shoe S is moved in parallel while slightly floating from the footrest 4 so that the shoe air is blown out from the outlet 22d so that the shoe S A part of the water droplets or dust is blown off, and the other part of the water droplets travels along the floor surface of the shoe S and is driven into the heel side of the shoe S. Drops of water, dust, etc. attached to the surface are blown away. Then, the shoe S is dried by repeating such a parallel moving operation several times as the case may be.

In the above embodiment, compressed air is simultaneously blown out from the nozzle units 20 and 30. However, in actual drying, since one shoe S is dried, one It is better to concentrate the output on one of them.

Therefore, for example, as shown in FIG. 6, when drying one shoe S, the one shoe S is placed on the footrest 3.
Since the other shoe S is in a state of being in contact with the footrest 4, a pressure sensor 5 for detecting the other shoe S is provided on the footrest 4. When there is an output, the pressure fluid is blown out only from the nozzle unit 20 side. When the other shoe S is dried, the other shoe S is placed on the footrest 4.
Since one shoe S is in contact with the footrest 3, a pressure sensor 6 for detecting the one shoe S is provided on the footrest 3. The pressure fluid can be blown out only from the nozzle unit 30 side when there is an output. The switching of the blowing of the compressed air from each of the units 20 and 30 can be performed by providing a switching valve or the like.

In the above-described modification, the opposite side of the shoe S to be actually dried is detected. However, as shown in FIG. 7, the light emitting sensors 7a and 7a are provided in the nozzle units 20 and 30.
8a and light-receiving sensors 7b and 8b,
It is also possible to control the switching electromagnetic valves 7c, 8c provided in the middle of the pipe so that the pressure air is blown out only from the nozzle units 20, 30 on the detection side of the sensors 7, 8.

When these detecting means are provided, the shoes S can be dried only by a series of walking operations, in combination with the fact that the compressed air is not reduced by half in units. .

[0037]

As described above, the shoe dryer according to the first aspect includes two sets of nozzle units for blowing out the air supplied from the air supply / exhaust device from the outlet, and the two sets of nozzle units. By disposing the nozzle units in the front-rear direction, it is possible to prevent water droplets and the like from adhering again after removing the water droplets and the like from the shoe surface.

A shoe dryer according to a second aspect of the present invention is provided with a detecting means for detecting that a shoe or a leg is located in each of the two sets of nozzle units. Since the air is wiped only from the outlet of the nozzle unit that has detected the air, the output of the compressed air supplied from one air supply / exhaust device can be effectively used.
