[0015]

[Embodiment] Hereinafter, a first embodiment of the present invention will be described with reference to FIG. The first embodiment shows the case of shoes, and the shoe main body 1 which is the footwear main body is an inner boot 1B which is excellent in heat retention and flexibility inside the plastic outer boot 1A, such as ski shoes and mountain climbing shoes. In addition, a heat storage material 3 such as sodium acetate, a planar self-temperature control type electric heater 4 and a heat insulating material 5 such as urethane foam are provided on the bottom 2 of the outer boot 1A from above. In addition, on the heel of the bottom part 2, an adapter terminal 7 as a connecting part which is detachably connectable to an outlet adapter 6 for supplying a commercial power source as an external power source is connected to the electric heater 4. There is. The planar self-temperature control type electric heater 4 is arranged substantially horizontally so as to face the sole of the foot.

Next, the operation of the above configuration will be described. Before use, when the outlet adapter 6 connected to the commercial power source is connected to the adapter terminal 7, the electric heater 4 heats up, warms the shoe body 1 and at the same time the heat storage material 3 stores heat. At this time, since the electric heater 4 is a self-temperature control type, for example, when the temperature is 40 degrees Celsius or more, the resistance automatically increases and the amount of heat generation decreases, while when it becomes 35 degrees Celsius or less, the resistance automatically changes. The calorific value increases with a decrease. Due to the heat generated by the electric heater 4 as described above, the shoe body 1 is warmed, and at the same time, a large amount of heat is stored in the heat storage material 3.

Next, when using, the outlet adapter 6 is removed from the adapter terminal 7 and shoes are used. At this time, the heat stored in the heat storage material 3 is dissipated and the shoe body 1 is warmed, so that it is possible to operate without the foot cooling.

As described above, according to the embodiment of the present invention, the shoe body 1 is provided with the electric heater 4 and the heat storage material 3 is provided in the vicinity of the electric heater 4 according to claim 1. When not in use, the electric heater 2 generates heat to store heat in the heat storage material 3, and in use, the heat stored in the heat storage material 3 is radiated to warm the shoe body 1, so that the user can freely act. In addition, since the shoe body 1 itself is warmed, energy can be saved, and dust is less likely to be generated due to the heating such as air conditioning equipment without air flow.

In addition, in the embodiment of the present invention, according to claim 2, the heat storage material 3 and the electric heater 4 are disposed on the bottom portion 2 of the shoe body 1, and the heat storage material 3 and the electric heater 4 are provided. Since the heat insulating material 5 is provided on the lower side, the foot can be warmed from the bottom portion 2 side of the shoe body 1, and the heat insulating material 5 does not wastefully transfer the heat to the ground side. It is possible to warm the shoe body 1 for a long time without waste.

Further, according to an embodiment of the present invention, in accordance with claim 3, the shoe body 1 is an adapter as a connecting portion which is detachably connectable to the outlet adapter 6 which is an external power source and is connected to the electric heater 4. By providing the terminal 7, a commercial power source can be easily connected to the electric heater 4.

In addition, in the embodiment of the present invention, according to claim 4, since the electric heater 4 is of a self-temperature control type, temperature control can be performed without using a temperature sensor, thereby achieving compactness. be able to. Further, since the electric heater 4 has a planar shape, it is possible to prevent local heat generation and the like and heat it uniformly.

FIG. 2 shows a second embodiment of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. A magnetic material 12 such as iron powder is provided in a sheet shape inside the shoe body 11, while a high-frequency current generator 13 for irradiating the magnetic material 12 of the shoe body 11 with a high-frequency current (microwave) W is provided. It is installed on the wall and ceiling of the work room.

Therefore, when the shoe body 11 is used in a refrigerating or freezing warehouse, and the high frequency current generating device 13 is operated to irradiate the high frequency current W, the magnetic material 12 generates heat by electromagnetic induction and the shoe body 11 Can be maintained at an appropriate temperature.

As described above, in the above embodiment, the shoe body 11 having the magnetic material 12 according to the fifth aspect and the high frequency current generator 13 for irradiating the shoe body 11 with the high frequency current W are provided. This makes it possible to provide shoes that allow free work without being restricted by electric cords. Moreover, since only the shoe main body 11 can be heated without heating the work space, energy can be saved, and dust is less likely to be generated because the heating does not involve an air flow like air conditioning equipment.

The present invention is not limited to the above-mentioned embodiment, but various modifications such as footwear such as slippers, sandals and the like other than shoes are possible.

[Effect of device]

 According to the first aspect of the present invention, the footwear body is provided with the electric heater, and the heat storage material is provided in the vicinity of the electric heater, whereby the heating footwear can be provided which can be freely activated without being restricted by the electric cord or the like. In addition, since the footwear body itself is heated, energy saving is achieved, and there is no fear that dust or the like will be generated due to the heating air flow such as air conditioning equipment.

According to a second aspect of the present invention, the electric heater and the heat storage material are provided at the bottom of the footwear body, and the heat insulating material is provided below the planar heater and the heat storage material. The heat storage material can heat the foot from the bottom side of the footwear, and the heat insulation material can provide the heating footwear that can be used for a long time without the heat of the heat storage material being transferred to the ground side or the like.

According to a third aspect of the present invention, the footwear body is provided with a connecting portion which is connected to the electric heater and can be detachably connected to an external power source, so that the external power source can be easily connected to the electric heater. You can

According to a fourth aspect of the present invention, since the electric heater is a planar self-temperature control type, a temperature sensor or the like is not required, and it is possible to achieve compactness and uniform heating. .

According to a fifth aspect of the present invention, there is provided a footwear for heating, comprising: a footwear body having a magnetic material; and a high-frequency current generator for irradiating the footwear body with a high-frequency current. The warmth is maintained even when used for a long time, and since the footwear body is heated, it is possible to save energy. In addition, the work can be performed without being caught by the electric cord, and dust and the like due to the air flow of heating such as air conditioning equipment are not easily generated.
