Abstract

PROBLEM TO BE SOLVED: To warm one's feet setting in an assistant driver's seat whose movement is less by providing a heat radiating plate, an exothermic body and a heat insulating material, sandwiching the exothermic body between the heat radiating plate and the heat insulating material, and supplying power from a cigarette lighter. SOLUTION: An electric heating means has an exothermic body 3 stuck on the back of a heat radiating plate 2 with a pressure sensitive adhesive double coated tape 4 and an aluminum foil 5 and is composed of a heat insulating material 6 and protection plate 7. The heating means is contrived to have power supplied through a plug 8, which is inserted into an automobile cigarette lighter socket, and a power source cord 9, and to have power supply automatically stopped when an engine key is switched off so that a battery is not charged with excessive load. By incorporating an excessive temperature rising prevention device 10 in an electrical circuit, the temperature of the heat radiating plate may not make an abnormal rise, and by incorporating an automatic temperature adjuster 11, the surface temperature of the heating radiating plate 2 can be freely adjusted to a desired degree and a preferable temperature can be automatically maintained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric heating device using a battery of an automobile as a power source.

[0002]

2. Description of the Related Art Conventional vehicle heating is to warm the inside of a vehicle with warm air heated by a heat exchanger using hot water from a radiator of an automobile. An air conditioner system blows warm air to the feet. , Cold wind is blown from the front panel to prevent the windshield and side windows from becoming frosted.

[0003]

However, in the conventional structure as described above, even if the moving driver is provided with comfortable heating, the person sitting in the passenger seat, which does not move much, has a warm upper body. , I had a problem with my lower body, especially my feet.

As described above, it is possible to comfortably heat the feet of the person sitting in the passenger seat with the conventional structure, and at the same time, to reduce stress in the comfortable environment for the driver so that the driver can drive safely. It was difficult.

The present invention solves the above-mentioned conventional problems by assuring the driver a satisfactory environment with the conventional system, and the person sitting in the passenger seat extends his / her legs by removing his / her lower legs, The object of the present invention is to provide comfortable heating by radiating far-infrared rays from the electric heating equipment attached to the.

[0006]

In order to solve the above problems, an electric heating tool of the present invention comprises a surface material 1, a heat radiating plate 2, a heating element 3 and a heat insulating material 6, and the heating element 3 is , Is sandwiched between the surface material 1 and the heat dissipation plate 2 and the heat insulating material 6,

The radiation of the heat is made uniform by subjecting the material of the heat radiation plate 2 to a ceramic having a good radiation efficiency of far infrared rays, a enamel finish, or a black body coating treatment.

Electricity is supplied from a cigarette lighter socket of an automobile, and electricity is supplied only when the engine is operating and the generator is generating electricity, so that an unnecessary load is not applied to the battery.

The shoe case, which can be opened and closed, is incorporated into the footrest so that the lower foot can be stored.

[0010]

According to the present invention, the heat insulating material 6 for insulating the heat inside the shoe case from the heating element 3 has the above-mentioned structure.
Far-infrared radiation from the heat dissipation plate 2 is uniformly and efficiently performed, and a comfortable heating effect can be obtained at the feet.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, in the electric heating tool of the present invention, the heating element 3 is adhered to the back surface of the heat dissipation plate 2 with the double-sided adhesive tape 4 and the aluminum foil 5, and the heat insulating material 6 and the protection plate 7 are provided. It is composed of.

A large amount of radiant heat is emitted by enamel finishing the surface of the heat dissipation plate 2 of the above-mentioned constituent material with a good radiation efficiency of far infrared rays, improving the circulation of blood on the soles and feet,
It is designed to contribute to health as well as heat collection.

FIGS. 3 and 4 show that the electric warming tool shown in FIG. 1 is incorporated into the foot rest of the openable shoe case so that the lower legs can be taken off and stored in the shoe case.
By placing it on the footrest part in a state close to bare feet, blood circulation can be enhanced and comfortable heating can be obtained due to the far-infrared ray effect.

Electricity is automatically supplied from a plug 8 to be inserted into a cigarette lighter socket of an automobile and a power cord 9, so that the electric power is automatically stopped when the engine key is turned off so as not to overload the battery. I did it.

The electric warming tool having the above-mentioned structure does not require a troublesome electric wiring work due to the dedicated plug 8 and the power cord 9 and is easily attached.

Since the heat dissipation plate 2 is prevented from abnormally increasing in temperature by incorporating the overheat prevention device 10 in the electric circuit, burns, fires, etc. are prevented and safety is ensured.

In this embodiment, the surface of the heat radiating plate 2 is enamel finish, but the material of the heat radiating plate 2 may be ceramic material, or the surface of the heat radiating plate 2 may be painted finish having a far infrared effect.

By incorporating an automatic temperature controller in the electric circuit of the electric heating tool of the present invention, the surface temperature of the heat radiating plate 2 can be freely adjusted to a desired temperature, and a desired temperature can be automatically maintained.

[0019]

As is apparent from the above embodiments, according to the electric warming tool of the present invention, the surface material 1, the heat radiation plate 2, the heating element 3, the heat insulating material 6 on the back side, and the protection plate. 7, the heat generating element 3 is constructed by being sandwiched between the heat radiating plate 2 and the heat insulating material 6, and is incorporated in a shoe case that can be opened and closed, so that the following effects can be obtained.

Since the radiator plate 2 is incorporated in the footrest part of the shoe case capable of opening and closing the electric warming tool, which is made of a material having a good radiation efficiency of far infrared rays, it is installed in the front passenger seat even if the heating of the automobile is stopped for the convenience of the driver. Comfortable heating is ensured at the feet of people sitting on the floor, which promises a relaxing and comfortable drive.
