Description

  The present invention relates to a chair with a heating function.

Air temperature / humidity adjustment in large spaces such as offices where many office desks are lined up, especially when heating in the winter, has traditionally been done by installing a heating device such as an air conditioner or blowing hot air from the floor or wall. There was one by floor heating laid on the whole floor.
However, in these methods, heating is performed even in a space where no people are present, which is wasteful and inefficient. Furthermore, there is an indication that cooling from the floor cannot be eliminated because warm air moves upward in the room.
Therefore, as a method of individually warming up, such as when working on a computer at each office desk while sitting on a chair, or when sitting on a sofa in a conference room, a foot heating / heating mat is placed or laid on the floor. It was common to install an electric stove in the room.
However, commercial fabric foot temperature heating mats are severely damaged when stepped on with shoes and are not suitable for office floors. In addition, there is a problem that the electric stove placed at the foot is not suitable in an office where paper or the like is scattered because there is a risk of ignition.

Uniform air conditioning in a large space is performed regardless of the personal temperature sensation of the person in the room, and the problems caused by air conditioning based on the provisions of average temperature and average humidity (too cold or too hot by people) Or the problem of providing a bad environment for people who are dry or unwell.

The problem to be solved is that, in consideration of the conventional heating method on the office floor, a personal seating activity area such as a personal computer desk (the floor area in the range where office activities such as personal computer operation and office work and office work are performed) It is a problem whether heating of the floor in a state where the foot is stretched or in a state where the legs are extended forward) can be efficiently and safely performed at low cost.
As a result, it is a problem whether personal heating in the office can be efficiently and economically performed and the entire floor can also be economically heated.
Of course, the idea of warming the seat surface of the chair can be seen in some ways, but the present invention is not the idea of warming the seat surface itself.
JP-A-10-43002 JP-A-8-140778

In order to solve the above problems, the present invention focuses on the lower space of a chair or sofa when seated and has a minimum seating area (a range of activity in a seated state or a state where a leg is stretched forward). A suitable heating means for floor heating is devised.
Here, the chair with a floor heating function according to the present invention has a sheet heating sheet that is energized with a 100 V power source and radiates far infrared rays, arranged in a drawer shape, a roll shape, or a folded shape in the lower space of the chair or sofa seat. A structure that can be pulled down and laid down on the floor or deployed and laid down on the floor when in use, dissipates heat by the far-infrared effect, and heats the upper area of the chair, the surrounding area, and the cooling of the feet Propose.
Therefore, it is completely different from a conventional chair such as a chair with a built-in heater in a seat or a sofa with a built-in heater in a backrest.
A major feature of the present invention is that it is a personal floor heating from below rather than a chair or sofa itself.

Specifically, a panel containing a sheet-like heat generating sheet is mounted and disposed in the lower space of a stool such as a chair, and when used, the panel is deployed and laid directly below or in front of the chair to cool the feet. Provided is a chair with a heating function characterized by heating and heating together with a far-infrared effect.
This chair with a floor heating function has a configuration in which a panel containing a sheet heating sheet is installed in the lower space of a stool such as a chair or a sofa. The cover is refracted or suspended or cabinetd in the space below the stool, and when used, the panel is spread on the floor, energized, and the seating area such as a chair or sofa is heated. To do.
The sheet heating sheet is provided with energizing means (switch, temperature controller, lead wire cord, etc.) for energizing from the office power source.
The sheet-like heat generating sheet has various functions that are employed in electric heating (Class A Electrical Appliance Certification No. 81-20610 Japan, USA UL, UK BBA, etc.). Those that emit infrared light are selected.
This is because floor heating in the seating area is basic, not just heat transfer heating by contact.
The sheet heating sheet radiates far infrared rays upward from the lower space of the chair or sofa and heats the body itself by electric heat, thereby warming the seating activity area.
If the form which can be stored compactly under a chair or a sofa can be adopted for the sheet heating sheet, its structure and material are not limited. In the present invention, the sheet can be folded, and the roll can be wound into a thin form. A form that can be pulled out and used can be proposed.
In any case, the sheet heating sheet adopts a configuration in which a storage form that can be folded compactly during storage and a deployment form that can expand the area during use is adopted.

The sheet heating sheet is made of silicon rubber or Teflon (registered trademark) as a binder, and carbon fiber is baked on a carbon fiber cloth, and copper foil is sewn and extended in the longitudinal direction as connection terminals on the left and right ends thereof. The + and-electricity flows through the copper foils at both ends of the sheet, thereby generating heat from the entire surface.
As the sheet heat generating sheet, a sheet heat generating sheet of Flexel (trademark) manufactured by FLEXEL in the UK, which has acquired safety standards, can be used.
In addition, the sheet heating sheet is made by attaching carbon or ceramic to glass fiber cloth or kneading it, forming it into a very thin sheet shape, and extending the connection terminals on the left and right edges, and energizing the connection terminals Therefore, it is a flat heating sheet that generates heat uniformly, emits far infrared rays, and can heat and heat.
When the sheet-like heat generating sheet is used on the floor in the present invention, a guard cover is provided on the front surface so as to protect it with a tile carpet and the like, and a heat insulating plate such as a heat insulating plate is used so as to insulate and effectively use the back surface. Panels are provided with materials.
For the guard cover, an insulating material such as wood, synthetic resin tile carpet, vinyl chloride, or acrylic material can be used.
If FRP (glass cloth / urethane base material) is used for the guard cover, not only a flat shape but also a curved surface can be formed, and 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.
When an aluminum alloy panel is used as the guard cover, it may be insulated from the copper foil with an insulating layer and a cloth carpet may be stretched on the mounting 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 a power of about 100 V and about 60 W to generate heat.
A chair with a heating function equipped with a panel according to this configuration is for heating a personal minimum seating activity area around and in the front area (the range where the user is seated and stretched) with far-infrared radiation. It is an economical electricity usage fee, and can be used for efficient personal heating because it does not emit excessive radiation in the minimum range.

By performing the minimum air conditioning in a large office space and personal heating at the individual level, it is possible to economically realize an optimal heating environment for each individual.

The effect which does is obtained.
(1) By using the chair with the heating function of the present plan, personal heating can be performed, the setting of the existing heating temperature can be kept low, and the energy saving effect is great. Moreover, since the electric power required for the heat generation of the planar heat generating sheet is 100 V, 50 W to 70 W and the electricity cost is extremely low, it leads to a significant reduction in heating cost.
(2) The temperature can be set individually, and comfortable heating can be realized by maintaining the optimum temperature for each person.
(3) In addition to the above effects, it is possible to achieve cold head heat by eliminating the coldness of the feet, improving the office environment and improving the office efficiency.

The sheet heating sheet 14 is a thin sheet heater, which is made of silicon rubber or Teflon (registered trademark) as a binder and carbon is baked on a glass fiber cloth. This is a stretched sewing, and has the effect of generating heat from the entire surface when + and-electricity flows through the copper foil at both ends of the sheet.
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 in the 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.

As shown in FIGS. 20 and 21, the sheet heating sheet 14 has a triple structure, that is, a tile carpet 13, a heating element 14, and a heat insulating body 15.
Further, the plurality of sheet heating sheets 14 can be connected by lead wires.

  Some of the tile carpets include aluminum alloy panels. The aluminum alloy panel is made of a flat panel developed for the OA floor.

Thus, far infrared rays directly give heat energy to the human body, so that even in an office floor with a large area, it is possible to efficiently warm a person's feet and achieve head cold foot heat.
In addition, since the sheet heating sheet 14 is extremely thin or can be refracted and folded, it is disposed in the space below the stool 1 so that no special space is required.

In recent years, global warming is regarded as a problem, and countermeasures are becoming urgently needed.
In any era, cost reduction is a reasonable issue.
Among them, office utilities account for a large percentage, and many managers are very interested in reducing it.
The present invention can not only significantly reduce heating costs by personalizing or improving the efficiency of the entire heating system on the office floor, but can also achieve a healthy and comfortable office environment by achieving cold head heat.
Conventionally, office heating has been developed in various ways, but the chair with floor heating function of the present invention can withstand use on the office floor where mobility and safety are required and has a large market. It is guessed.
The chair with a floor heating function in which the sheet heating sheet according to the present invention is arranged achieves energy saving management by protecting the current global environment or reducing costs as described above, and above all, providing a healthy and comfortable office environment. It can be said that it is groundbreaking in that it leads to building and improving work efficiency.
