DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair and a far-infrared radiation panel having a heating function.

[0002]

2. Description of the Related Art Conventionally, hyperthermia has been used to treat stiffness or pain in body parts such as the hips, shoulders, and neck. In the hyperthermia treatment, for example, the affected part is heated by irradiating the affected part with infrared rays using an infrared lamp. Thereby, blood circulation of the affected area is improved, and stiffness or pain is removed or alleviated.

In order to easily carry out thermal treatment, for example, as shown in FIG. 18, an electric cushion 53 is placed on a seat 51 of a chair and the user sits thereon, and the back and the back of the chair (back). For example, a waist rest heater or a thermal cushion 54 having a built-in nichrome wire heater is sandwiched between the heater 52 and the heater 52. Thereby, the electric cushion 53 and the warm cushion 54
, Heat is directly conducted to the human body, and the conduction heat warms the affected part.

[0004]

However, FIG.
In the conventional thermal treatment method shown in (1), since the affected part is warmed by the conduction heat method, a thermal effect cannot be obtained unless the affected part is always in contact with the heating part of the electric cushion 53 or the heating cushion 54. Therefore, you cannot move during treatment, and you have to feel tight. Further, if the affected part is in contact with the heat generating part for a long time, the affected part may be stuffy due to sweat or the like.

Further, since it is difficult to uniformly apply pressure to the heat generating surface due to unevenness of the human body, the thermal effect becomes uneven between a high pressure portion and a low pressure portion. Further, in the case of the conduction heat method, the electric cushion 53 or the thermal cushion 54 is used.
Since heat is conducted from the heater incorporated in the device to the human body through the cushioning material, the surface material, and the like, it takes time from when the power is turned on to when the human body is warmed, and there is a problem that a response time in temperature adjustment is long.

An object of the present invention is to provide a chair having a heating function for warming a human body comfortably, uniformly and quickly. Another object of the present invention is to provide a far-infrared radiation panel having a thermal function of warming a human body comfortably, uniformly and quickly.

[0007]

According to a first aspect of the present invention, in a chair having a seat and a back, a recess is formed in the seat or the back, and a planar heating element is attached to the bottom in the recess. Mesh member, lattice member, multiple rods in the opening of
Member, a sheet-like member having a plurality of holes, or a plurality of sheets.
A sheet-like member having a lit is attached, and an energizing means for energizing the planar heating element is provided.

The seat and the back are a core material and a cushion material.
Made of core material and cushion material for the seat or back
A concave portion may be formed . In particular, it is preferable that the sheet heating element is made of carbon fiber mixed paper.

A far-infrared radiation panel according to a second aspect of the present invention comprises:
A planar heating element that radiates far-infrared rays is attached to the bottom of the panel with a concave cross section, a ventilation cover member is attached to the opening of the panel, and an energizing means for supplying electricity to the planar heating element is provided. is there.

As the cover member, any of a mesh member, a lattice member, a plurality of rod members, a sheet member having a plurality of members, and a sheet member having a plurality of slits may be used. In particular, it is preferable that the sheet heating element is made of carbon fiber mixed paper.

[0011]

In the chair according to the first aspect of the present invention, when a sheet heating element is energized by energizing means while a person is sitting on the chair,
Far infrared rays are radiated forward from the heating surface of the sheet heating element. The far-infrared radiant energy reaches the human body through an air layer between the sheet heating element and the cover member and the cover member, and activates the molecular motion inside the human body. As a result, the body part is effectively warmed.

In this chair, since the human body is warmed by the far-infrared radiant heat method, a thermal effect can be obtained without the human body coming into contact with the heat generating portion. Therefore, even if the body is moved, a uniform heating effect can be obtained due to the linearity of the radiant energy. In addition, since an air layer having good air permeability exists between the human body and the heat generating portion, the human body is not stuffy due to sweat or the like. Furthermore, because it uses radiant heat,
Irrespective of the non-uniformity of the pressure on the chair due to the unevenness of the human body, the human body can be heated uniformly.

Further, since far-infrared rays radiated from the planar heating element directly apply heat energy to the human body without passing through the air, the time from when the power is turned on to when the human body warms is greatly reduced. Furthermore, since there is no cushioning material or surface material between the planar heating element and the human body, the heat capacity of the heating element is reduced, and the response time for temperature adjustment is greatly reduced.

In the far-infrared ray radiating panel according to the second aspect of the present invention, when current is supplied to the sheet heating element by the energizing means, far infrared rays are radiated forward from the heating surface of the sheet heating element.
The radiant energy of the far-infrared rays travels straight and reaches the human body, activating molecular motion inside the human body. as a result,
Parts of the human body are effectively warmed.

In this far-infrared radiation panel, an air layer is formed between the planar heating element and the cover member. Thereby, the heating effect and the heating effect are uniformly given to the part of the human body by the far-infrared radiation heating method without the human body coming into contact with the heat generating part. In addition, since heat energy is given to the human body by the radiant heat method, the time from when the power is turned on to when the human body is warmed is greatly reduced, and the response time in temperature adjustment is also significantly reduced.
