Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a foot heater that is used by appropriately placing it under a desk, etc., and in particular, the floor surface is made of concrete or cold-sensing material. This invention relates to an energy-saving foot warmer that is suitable for offices and workplaces.

(Prior art and its problems) Conventionally, kerosene stoves, electric fan heaters, and the like have been used in most cases as heating equipment in general homes and offices.

However, it is a fact that everyone knows from experience that when a room is heated, the heat rises, creating a temperature difference between the upper and lower parts of the room.

Moreover, in this case, even if you want to warm your feet in particular, it will only warm your upper face, shoulders, etc.
It is impossible to heat a desired area without overheating the entire room, which is inefficient and wastes a lot of energy.

In addition, in order to be able to respond immediately to the above situation, recently,
Electric carpets have been developed and are widely used, but they are wasteful when used in places with few people, and are unsuitable for use with shoes on, especially in offices with concrete floors. in,
Another drawback was that it could not be used to warm the feet while sitting at a desk.

(Purpose of the invention) This invention was made in view of the above-mentioned problems, and can be used in offices and workshops where the floor is made of concrete or cold-sensing materials by simply placing it under a desk, etc. The purpose of this invention is to provide a foot warmer that has a compact design and an energy-saving effect that can efficiently heat the body.

(Structure of the invention) That is, the foot warmer of the invention includes a frame body in which a pair of gate-shaped rods are arranged facing each other, and a pair of connecting rods are installed in parallel between both sides of each upper end; An exterior material that can continuously cover the rear surface, upper and lower surfaces, and both side surfaces of the frame, and an exterior material that is inserted into the interior of at least one surface of the exterior material, and a finely powdered ceramic is applied to the entire area of the exterior surface, and the exterior surface of the ceramic is It consists of a grafted carbon ceramic radiant heat mat that is coated with fine powder carbon over the entire area and can conduct electricity.
It is characterized in that the heat generated from each radiant heat mat is reflected to the front opening side through an exterior material covering the frame body.

Hereinafter, the foot warmer of the present invention will be described in detail based on an embodiment shown in the drawings.

(Example 1) In the drawings, reference numeral 1 indicates an embodiment of the foot warmer of the present invention, and the foot warmer 1 includes:
A frame body 2 having a framework structure as shown in FIG.
As shown in FIG. 2, it is composed of an exterior material 5 that can continuously cover the frame 2, and a radiant heat mat 9 installed inside at least one surface of each surface of the exterior material 5. By disposing the heater under the desk or the like and supplying power to the radiant heat mat 9, the feet B of the user A can be heated to an appropriate temperature without waste, as shown in Fig. 5. It is something.

As shown in FIG. 1, the frame 2 is a gate-shaped rod 3 made by bending a bar or pipe material into a gate shape.
A pair of rods are arranged facing each other, and a pair of connecting rods 4 are installed in parallel between both sides of each upper end, and the height and width of the rods are determined as appropriate depending on the place of use. It is something that

In addition, as shown in FIG. 2, the exterior material 5 has a rear surface 6a and a double-sewn cloth material made of urethane, polyester, cotton, etc., to be attached to each surface of the frame 2 other than the front surface. It is constructed so that the upper and lower surfaces 6b, 6c and both side surfaces 6d, 6e can be continuously covered.

In addition, 7 in the figure is a rod insertion part provided in the exterior material 5 in order to insert the foot part 3a of the portal-shaped rod 3 of the frame 2 and integrate it, and 8 is a rod insertion part provided in the exterior material 5. This is a wiring housing portion provided in the exterior material 5 to house wiring 12, which will be described later, that supplies power to the radiant heat mat 9.

Furthermore, the radiant heat mat 9 is shown in FIGS. 3 and 4.
As shown in the figure, it is inserted into the interior of at least one surface of the exterior material 5 (in FIGS. 3 and 4, the inside of the rear surface 6a, the upper and lower surfaces 6b, 6c, and both sides 6d, 6e of the exterior material 5). For example, the outer periphery is covered with a nonwoven fabric (not shown) made of chemical fiber such as nylon, and a heat-resistant vinyl coated with silicone or the like on the outer surface of the nonwoven fabric. A heat-resistant heater wire (not shown) is installed inside the wire, and a finely powdered ceramic is applied to the entire outer surface of the wire, and finely powdered carbon 11 is applied to the entire outer surface of the ceramic. The heat generated from each radiant heat mat 9 passes through the exterior material 5 covering the frame body 2 and is transferred to the front opening side. It is designed to reflect light.

In addition, 12 in the drawing is this radiant heat mat 9.
This wiring is connected to the radiant heat mat 9 so that the power supplied from the power source is passed through this wiring to the radiant heat mat 9.

Further, the radiant heat mat 9 may be constructed by coating the entire outer surface with a grafted carbon/ceramic agent prepared by mixing finely powdered ceramic powder with grafted carbon in advance, and the effect will be the same.

Further, the fine powder carbon 11 of the radiant heat mat 9 is a heat generating material made of a conductive resin (carbon black graft polymer) based on carbon black, which is a black body, and the radiation area from this mat 9 is increased. It plays a role in Incidentally, the infrared rays emitted from this heat-generating material exhibit a radiation efficiency close to that of a buried black body, and the center of the radiation wavelength is in the 7-8 μm region at a heater temperature of 100°C, with a radiant energy of 1.1 KW/m ² It is something that has a quantity.

(Function of the invention) The foot warmer 1 of the invention is constructed as shown in the above embodiment. As shown in FIG. starts generating heat immediately and reflects the heat toward the front opening side of the frame body 2, making it possible to efficiently warm the foot portion B.

(Effect of the invention) As shown in the above embodiment, the foot warmer of the invention has a pair of gate-shaped rods facing each other, and a pair of connecting rods installed in parallel between both sides of each upper end. a frame body formed of a frame body; an exterior material capable of continuously covering the rear surface, upper and lower surfaces, and both side surfaces of the frame body; It consists of a grafted carbon ceramic radiant heat mat that can be electrically conductive, with finely powdered carbon applied over the entire outer surface of the ceramic, and the heat generated from each radiant heat mat is passed through the exterior material that covers the frame. This foot heater has a compact design that reflects heat toward the front opening, so unlike conventional heating equipment, it can be used in offices where the floor is made of concrete or cool material. It is possible to efficiently warm the feet even in the workplace, and there is almost no heat leaking to the outside, allowing radiant heat to be concentrated on the important parts.In addition, the radiant area is reduced by applying the grafted carbon/ceramic agent of the radiant heat mat. In addition to being large in size, far infrared rays are emitted from the radiant heat mat due to heater heat, which improves thermal efficiency and reduces power costs, making it highly valuable as it also has an energy-saving effect.
