Description

  The present invention relates to a floor heating seat that can be folded.

  2. Description of the Related Art Conventionally, as a heating device that has been adopted in a house or the like, a convection heating type heating device and a radiant heating type heating device using electricity, gas, and oil as fuels are mainly used.

  However, heating by a radiant heating type heater represented by a ceramic heater and a convective heating type heater represented by an oil stove, the temperature of the air in the upper space of the room is higher than that of the lower space, and when you sit in a chair I feel cold from the knee to the knee.

  In addition, air pollution due to combustion of gas or oil is inevitable and has a problem in safety.

Furthermore, since the above-mentioned heating device is large and heavy, there are problems such as being difficult to carry and restricting the place of use, and requiring a large storage space during the off season.
Various types of foldable electric heaters have been developed. There are some panels with notches for connecting wires so that the connection wires do not get in the way even if a panel with several electric heaters is folded. However, since the conventional product is an electric heater using a resistance wire, it has a thickness and does not emit far infrared rays and cannot be said to be suitable for floor heating.
JP 2000-205585 A

The problem to be solved by the present invention is whether the floor heating can be made light and compact and personal.
The conventional heating device has a problem in that it cannot perform efficient and maneuverable heating for personal individual heating.
That is, even in the heating for each room, even if the heating temperature is the same, depending on the person, the temperature may be insufficient or excessive.
Especially in office work, since it takes a long time to work around the desk, personal heating in the activity area becomes a problem.

In order to solve the above-mentioned problems, the present invention focuses on the lower space of the chair or sofa when seated and has a minimum seating area (the active range area when the user is seated or with the legs extended forward). A suitable heating means for floor heating is devised.
Specifically, we focus on utilizing the space from the chair stool to the floor (dead space), and even when performing individual floor heating, it is not necessary except during the winter, so floor heating equipment is A light and compact design has been devised to facilitate carrying and storage.

Here, the floor heating sheet according to the present invention is energized with a 100 V power supply, has a connection terminal on the left and right ends, and covers the surface of the sheet heating sheet that emits far infrared rays when energized with a tile carpet or the like, and the back surface with a heat insulating cover. The floor heating sheet is characterized in that the covered panels are connected in a refractive manner.
In the lower space of the chair stool, it is laid and laid out in use and dissipates heat by the far-infrared effect as partial floor heating, thereby heating the upper area of the chair, the surrounding area, and the cooling of the feet.

The floor heating seat is provided with energization means (switch, temperature controller, lead wire cord, etc.) for energizing from the wall outlet power supply.
By the way, the heat generating sheet has various functions that are adopted for electric heating if only looking at the shape (Class A Electrical Appliance Certification No. 81-20610 Japan / America / British A / etc.). Then, what emits far infrared rays is indispensable.
This is because the floor heating in the activity area around the desk and the seating area is basic, not just the heat transfer heating by contact.

The heating element emits far-infrared rays upward from the space below the chair, and the main body itself generates heat by electric heat, thereby warming the seating activity area.
The heating element is compact enough to be laid in the lower space of the chair, needs to be lightweight, and the present invention requires a structure that can be folded.
The floor heating seat adopts a configuration capable of a storage configuration that can be folded compactly during storage and carrying, and a deployment configuration that can expand the area during use.

A sheet heating sheet was used as the heating element.
The sheet heating sheet is a thin sheet heater. Silicon fiber or Teflon (registered trademark) is used as a binder, carbon is baked onto a glass fiber cloth, and copper foil is sewn in the longitudinal direction at the left and right ends. In this case, + and − electricity flows through the copper foils at both ends of the sheet, thereby generating heat from the entire surface.
From the raw material carbon, far infrared rays are efficiently emitted at a wavelength of 8 to 15 microns. In general, those having a wavelength of 5 to 100 microns are called far infrared rays. Among them, the wavelength band of 6 to 14 microns is called “growth light” and “health light”. It emits a wavelength band.

In addition to carbon, an appropriate ceramic may be mixed, kneaded into a non-combustible synthetic resin, molded into a sheet shape, and the wavelength band in the healthy light region can be selected.
Far-infrared radiation keeps the room temperature constant from floor to ceiling, and warm air does not collect only near the ceiling.
Since far-infrared rays directly warms the body, even in a high ceiling or a wide space, sufficient warming can be achieved at room temperature of 18 ° C. to 21 ° C., and heating efficiency is excellent.
Also, since it does not presuppose the use of a boiler or the like and there are no mechanical moving parts, maintenance such as periodic inspections and repairs is not necessary, and it can be said that the running cost is extremely economical.
Compared to floor heating that uses hot water pipes or heat wires, the sheet heating sheet of the present invention has a large area even at low temperatures, so the resistance value of the entire surface is large. The temperature was uniform and there was little temperature unevenness, and the temperature did not rise partly, and the electricity bill was reduced to about 1/3, and it was confirmed that the loss was low and efficient.

This planar heat generating sheet can be used other than the above as long as it is a flat heat generating sheet capable of generating heat uniformly, emitting far-infrared rays and heating and heating by energizing the terminals. .
By the way, it is not limited to those of the above manufacturing method, it is a configuration in which a mixed liquid such as carbon or ceramic is applied to a glass fiber cloth and molded into an extremely thin sheet shape, and terminals such as copper foil are bonded and extended to the left and right edges.

The sheet heating sheet used in the present invention is specially devised in the carbon and Teflon (registered trademark) coating and baking method, and the copper foil part through which electricity flows is sewn with a sewing machine, making it durable and durable Yes, but it can also have some effect if it is bent or scratched with a foreign object.
In the present invention, a guard cover is provided on the front surface so as to protect it with a tile carpet or the like, and a heat insulating cover such as a heat insulating plate is provided on the back surface so as to be effectively used.

The guard cover is made of an insulating material such as wood, synthetic resin tile carpet, vinyl chloride, or acrylic material.
If FRP (glass cloth / urethane base material) is used for the guard cover, not only a planar shape but also a curved surface can be formed. Colors and patterns are also free.
The guard cover can be made of a strong aluminum alloy panel. The aluminum alloy panel is a flat panel of a panel developed for OA floors, can sufficiently meet the demands on strength, has excellent heat conductivity, and has electromagnetic wave protection and far infrared radiation effect.
In the case of an aluminum alloy panel, the copper foil may be insulated by an insulating layer, and a cloth carpet may be stretched on the surface.
The guard cover may be made of stone such as marble or terracotta. Since the heat generation part is uniform at a low temperature, it does not give much stress to floor materials such as stones.
The sandwich panel is supplied with power of about 100 V and 40 W to 60 W to generate a heat generation function.

As described above, according to the above-described configuration of the floor heating seat according to the present invention, it is possible to create a personal environment in an arbitrary space that has been lacking in the conventional heating device, and sufficient heating effect and convenience and mobility. It is possible to provide a floor heating sheet having the characteristics.
That is, for example, it can be used by simply laying under a chair, and individual floor heating can be performed, such as cooling the feeling of feet or knees when sitting on the seating area and the chair.
It is efficient and reasonable because it can be done partially and individually.
Since the floor heating seat itself is lightweight and compact, it is easy to carry and is very convenient in that it does not choose a place and storage space.
Since it is a floor heating sheet having the above effects, it can contribute to a healthier, safer and more comfortable heating life simply.
In the office space, each person can personally adjust the environmental temperature.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing the configuration of Embodiment 1 of a floor heating sheet 1 of the present invention.
As shown in FIG. 1, the floor heating seat 1 of the present invention is configured by connecting four heating panels 1 a to 1 d.
The outer dimensions of one panel of the heating panels 1a to 1d are 30 cm in length and 25 cm in width.
One sheet has a total length of 30 cm in length and 110 cm in width including the panel length and the connecting portion.
The number of the heating panels 1a to 1a can be appropriately designed and the total length can be appropriately designed. However, it is preferable that the length of the two to six surfaces is one sheet and the total length is about 150 cm.
The panels 1a to 1d are electrically connected by connecting connection terminals 51 such as copper foil strips extending to the left and right ends of the heat generating sheet 5 to the panels 1a to 1d.
Only the left and right connecting terminals 51 of the heat generating sheet 5 are present as the refracting portion for connection, and the connecting terminal 51 is thin so that it can be refracted.

As shown in the cut-away perspective view of FIG. 9, the panels 1a to 1d are formed by attaching copper foil strips as connection terminals 51 to the left and right ends of the sheet body in which carbon is adhered to a glass fiber cloth and energizing the copper strips. The surface of the sheet-like heat generating sheet 5 that radiates far infrared rays is covered with a guard cover 4 and the back surface is covered with a heat insulating cover 6.
For the connection of the panels 1a to 1d, refracting portions 8, 9, and 10 are provided so as to be refractably connected so that they can be folded.
The refraction parts 8, 9, and 10 may have any configuration as long as they are refracted.
For example, the configuration in which at least two or more panels are refracted and electrically connected covers two or more of either the guard cover 4 that covers the surface of the substantially rectangular planar heating sheet 5 or the heat insulating cover 6 that covers the back surface. It is assumed that the lengths are connected at a slight interval, and the interval portion can be a refracting portion.
Although an extremely thin gap is formed between the guard cover 4 and the heat insulating cover 6, the panels 1a to 1d that are electrically adjacent to each other can be connected by connection lines using the gap.
In addition, a refractive member such as a minute hinge may be used.

The sheet-like heat generating sheet 5 is made by baking silicon on a glass fiber cloth using silicon rubber or Teflon (registered trademark) as a binder, and a copper foil band as a connection terminal 51 is sewn and extended in the longitudinal direction on the left and right ends thereof. It generates heat when it flows through the copper foil at both ends of the sheet when energized, emits radiant heat, and emits far-infrared rays.
The guard cover 4 that covers the surface of the sheet heating sheet 5 is an insulating material such as a tile carpet, vinyl chloride, or an acrylic material.
The guard cover 4 may be a highly stretchable cloth material, or may be a secondary material such as a water repellent material, or may be a laminated material.
There is no problem as a flooring material, and the material is not questioned as long as it has an insulated structure.
The heat insulating cover 6 is the same, and the material is not limited as long as the insulating structure does not waste heat.
The connection of the panels 1a, that is, the connection of the sheet-like heat generating sheet 5 is a structure in which at least two or more sheets are bent and electrically connected.
Further, the heat generating sheet 5 as a heat generating element is connected to an outlet via the electric cord 3, and the temperature is adjusted by the ON / OFF control and the controller by the manual power switch 2.

Next, the structure of the panels 1a to 1d will be described.
2 is a central sectional view of the heating panels 1a to 1d constituting the floor heating sheet 1 of the first embodiment of the present invention. As shown in FIG. 2, the heating panels 1a to 1d are tile carpets on the upper surface of the heating sheet 5. A guard cover 4 such as the above is pasted and a heat insulating cover 6 is stacked on the back surface to form a sandwich.
The thicknesses of the guard cover 4, the heat generating sheet 5, and the heat insulating cover 6 are each preferably 1 cm or less, and the total thickness of the heating panels 1a to 1d is preferably 3 cm or less.
The heat generating sheet 5 is made by kneading carbon, ceramic or the like into a glass fiber or a synthetic resin sheet and forming it into a very thin sheet, and extending connection terminals 51 on the left and right edges.
The present embodiment is an example in which a tile carpet is used as the guard cover 4, but a waterproofed vinyl chloride, acrylic material, or aluminum panel may be used.
The power required for heat generation of the heat generating sheet 5 is preferably 100 V and 40 to 60 W.

3 and 4 are perspective views for explaining how to fold the floor heating seat 1 according to an embodiment of the present invention.
As shown in FIG. 3, the tile carpet 4 of the floor heating sheet 1 of the present invention has refracting portions 8 to 10 and can be folded into an L shape.
In addition, an angle adjustment component can also be provided so that it can fix at arbitrary angles.
This embodiment can be fully folded as shown in FIG.
Although not shown, the folded panel 1a and the panel 1b can be configured so that the energization can be cut off at the refracting portion 10 as a boundary.
By this operation, a location requiring heating can be selected.

5 and 6 are perspective views when the floor heating seat 1 is developed in the lower space of the seat portion of the chair 7 when the embodiment is used.
As shown in FIGS. 5 and 6, the guard cover 4 of the floor heating seat 1 is positioned and deployed when in use.
As a result, the heat generation surface faces the upper side of the chair and expands to the front side, so far infrared rays converge from the feet of the sitting person to the knees to heat.
Furthermore, as shown in FIG. 6, by folding the floor heating sheet 1 and fixing it at an arbitrary angle, it is possible to radiate far-infrared rays intensively from the instep to the shin to further enhance the heating effect. is there.
Incidentally, by developing this embodiment, it is possible to propose a configuration in which the floor heating seat 1 can be stored in the lower part of the chair and pulled out and laid on the floor in relation to the chair.

FIG. 7 is a diagram illustrating a process when the floor heating sheet 1 is folded from the unfolded state when the embodiment is used.
As shown in FIG. 7, the floor heating sheet 1 can be provided with refracting portions 8 to 10 and can be folded, and can be fixed at an arbitrary angle.
When folding, first, the panels 1a and 1d are lifted upward with the refraction portions 8 and 9 as axes, and the panel 1a is folded so as to overlap the panel 1b and the panel 1d. Subsequently, the panel 1c and the panel 1d that are folded first with the refracting portion 10 as an axis are folded so as to overlap the panels 1a and 1b.
The thickness of the folded floor heating sheet 1 is preferably about 12 cm, and can be stored in a space-saving manner.
FIG. 8 is a perspective view of the folded state.

FIG. 10 is a perspective view of a structure in which four panels 1a to 1d are connected with the heat insulating cover 6 being long.
FIG. 11 shows a single panel with a built-in heat generating sheet.
The guard cover 4 and the heat insulating cover 6 are made of the same elastic material so that the front and back can be used reversibly.
Inside, there are four panels 1a to 1d, which are arranged at intervals.
Since the guard cover 4 and the heat insulating cover 6 are made of a stretchable material, it can be folded from this state.
The floor heating sheet 1 having this configuration can be attached to the lower side of the bed and used as a bed warmer. Compared to heating the entire room, this method only requires heating the bed, so the electricity bill is about 1/7, and the energy saving effect is great.

As described above, the floor heating seat of the present invention has the characteristics listed below.
(1) The floor heating can be partially performed, and due to the lightweight and compact design, it is portable and the use place and the storage place are not limited. This feature is presumed to be very convenient and in high demand in the housing situation in Japan where there are many small houses.
(2) The point that the individual floor heating by the very little power consumption of 100V and 60W or less is possible compared with the conventional heating apparatus. This feature is a natural consequence of adopting energy-saving designs that are becoming mainstream in response to recent global warming issues.
(3) The far-infrared heating that is easily absorbed by the body efficiently eliminates cold feet and achieves cold head heat. This feature takes advantage of the health, safety and clean nature of far-infrared rays and does not emit light, hot air, or sound, so it can be used in ordinary homes and medical facilities where there are children and the elderly.

  Various heating devices have been developed in the past, but the floor heating seat of the present invention is epoch-making in that it is a heating device that combines convenience, efficiency, health and safety with the above three features at the center. It can be used from ordinary households to elderly housing, medical nursing facilities, offices and schools that require large-scale heating devices, and it is assumed that there is a large market.
