Description

  The present invention relates to an electric warming tool such as an electric carpet.

  Conventionally, in order to save energy, this type of electric warming tool insulates the floor surface with an airtight air layer (see, for example, Patent Document 1). FIG. 4 is an external perspective view of a conventional electric warming tool described in Patent Document 1, and FIG. 5 is a cross-sectional configuration diagram thereof (however, the cover is not shown). As shown in FIG. The heating element 1 as a heat source is bonded and fixed to the front cloth 2, and a felt 4 having a heat insulating function is sandwiched between the backing 3 and the front cloth 2. The upper surface is covered with a cover 5 with good design.

As shown in FIG. 5 (however, the cover 5 is omitted), the backing 3 is composed of a sheet 6 and a sheet 7, and the sheet 7 has hemispherical projections on the entire surface, and A hemispherical air layer 8 is formed with the sheet 6. The hemispherical tip of the air layer 8 is in contact with the floor surface 9. Thus, by providing the air layer 8 between the heating element 1 and the floor surface 9, heat radiated to the floor surface 9 is suppressed and energy saving is achieved.

  Recently, there is a concern about the depletion of earth resources, while further energy saving is demanded. However, the conventional configuration described above cannot be said to satisfy the demand sufficiently. An object of this invention is to provide the electric warming tool which can respond to the energy saving which is the request | requirement of the said society.

  In order to solve the above-mentioned conventional problems, instead of the air layer, a space layer having a reduced pressure or a near-vacuum pressure state in which the heat insulation effect is far superior to the air layer is provided between the heating element and the floor surface. Formed.

  Thereby, useless heat radiation from the heating element to the floor surface can be suppressed by a space layer having a pressure state close to reduced pressure or vacuum.

  The electric warming tool of the present invention can further save energy by suppressing wasteful heat radiation from the heating element to the floor surface.

  1st invention is equipped with the heat generating body and the main body which consists of a base material which covers the said heat generating body, and when the said main body is laid in the floor, between the said heat generating body and a floor surface, pressure | pressure close | similar to pressure reduction or a vacuum By providing the space layer having the state, more energy saving can be achieved by suppressing wasteful heat radiation from the heating element to the floor surface.

  In the second invention, in particular, since the space layer of the first invention is composed of a container having a reduced pressure or a pressure state close to vacuum, a heavy object is dropped on an electric warming tool or a carriage is passed. Will not be crushed.

  In the third invention, in particular, when the base material of the first and second inventions is a soft foam and the main body is laid on the floor, a pressure state close to reduced pressure or vacuum is formed inside the surface in contact with the floor surface. By providing the container (space layer) having the container, the container does not protrude to the outside of the main body, so that the back surface of the main body and the floor surface can be brought into full contact with each other, thereby preventing displacement of the main body in use with respect to the floor surface.

  In the fourth aspect of the invention, in particular, the space layer (container) is provided at a position facing the heating element, so that the space layer (container) is provided between the heating element having the highest temperature and the floor surface. Therefore, the heat radiated to the floor can be effectively cut off, and further energy saving can be achieved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional configuration diagram of an electric warming tool according to Embodiment 1 of the present invention. In FIG. 1, the same reference numerals as those described in the background art are assumed to have the same structure. In the figure, a container A11 (spatial layer) having a pressure state close to reduced pressure or vacuum is disposed on the backing 10 at appropriate intervals over the entire surface of the backing 10.

  About the electric warming tool comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The heat dissipated from the heating element 1 to the floor surface 9 can be insulated by the container A11 having a pressure-reducing or near-vacuum state that has a much more heat-insulating effect than the air layer. As described above, in the form of the present embodiment, further energy saving can be achieved by performing heat insulation with the container A11 having a heat insulation effect much more than the air layer.

  In the present embodiment, when a hard felt is used, a gap may be formed between the outer cloth 2 and the felt 4 depending on the thickness of the heating element 1, as shown in FIG. There is no influence on the configuration and effect of the present invention.

  In the present embodiment, the container A11 (spatial layer) is arranged at an appropriate interval over the entire surface of the backing 10. However, the container A11 is used as a small capsule and the interior of the substrate 4 is used. Even if it arrange | positions in, the same effect is acquired.

(Embodiment 2)
FIG. 2 is a cross-sectional configuration diagram of the electric warming tool according to Embodiment 2 of the present invention. In FIG. 2, components having the same reference numerals as those described in the background art and the first embodiment have the same structure and will not be described. In the figure, the container A11 is located inside the backing 10 (inside the main body). This is because the soft foam 12 can be filled with a chemical reaction by mixing two liquids, so that the gap between the front cloth 2 and the backing material 10 can be filled without any gaps. It can be configured as follows.

  About the electric warming tool comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the container A11 is inside the main body, the backing material 10 can be in contact with the entire surface 9 while saving energy by the heat insulating effect of the container A11.

  As described above, in the present embodiment, since the container A11 is configured inside the main body, the backing 10 comes into contact with the entire floor surface 9, and the main body in use can be prevented from being displaced with respect to the floor surface 9. . Further, since the container A11 is configured inside the main body, the amount of the flexible foam 12 corresponding to the volume of the container A11 can be reduced, and resource saving can be achieved.

(Embodiment 3)
FIG. 3 is an external perspective view of the electric warmer according to the third embodiment of the present invention. In FIG. 3, the same reference numerals as those described in the background art and Embodiments 1 and 2 are assumed to have the same structure. In the figure, the backing 10 is provided with a container B13 having a reduced pressure or a pressure close to a vacuum in a shape facing the heating element 1 along the heating element 1.

  About the electric warming tool comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, since the temperature of the heating element 1 is the highest, the temperature gradient from the heating element 1 toward the floor surface 9 is large, and the heat dissipation in this part is large. Therefore, by providing the container B13 without a gap between the heating element 1 and the floor surface 9, heat radiation can be further suppressed.

  As described above, in the present embodiment, the container B13 is provided between the heating element 1 and the floor surface 9 without a gap, thereby insulating the entire portion where the temperature gradient from the heating element 1 toward the floor surface 9 is large. Energy saving can be achieved by providing an effective container B13.

  As described above, the electric warming tool according to the present invention combines energy saving by heat insulation of the space layer and prevention of displacement due to the size of the contact surface, so that it is a warming tool laid on a surface such as a floor surface. Useful.
