Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air-conditioned chair, more specifically a chair suitable for use as a chair in a vehicle such as an automobile or an airplane, or as a chair in a theater or a hall. This relates to an air-conditioned chair that is equipped with an air-conditioning device and can warm or cool the person sitting on it.

[Prior Art] Many chairs have conventionally been used inside a vehicle or in a theater.

Places where such chairs are installed are usually equipped with indoor heating and cooling equipment to prevent the person sitting on the chair from getting too hot or cold.

[Problem that the invention attempts to solve] However, conventional cooling and heating like this.

In order to integrally cool and heat the inside of the car or the interior of the car,
Even if the interior of the vehicle was cooled or heated, the interior of the vehicle or the chairs provided inside the vehicle did not become warm or cold.

For example, even though the inside of a car or the room is cooled by air conditioning, the chairs that people actually sit on do not get cold, and when people sit on those chairs, they sometimes sweat on the parts that are in contact with the chairs. In particular, in the case of chairs installed in vehicles such as cars, and in the case of cars parked in Entian Ding, the chairs become hot due to the sunlight. It was becoming difficult for the occupants to feel that they were getting cold. Furthermore, when riding for an extended period of time, even if the room was air-conditioned, the cold air did not circulate between the chair and the person sitting, and only the parts that were in contact with the chair would sweat. .

Conversely, even when the inside of a car or the room is heated, the warm air flows only into the inside of the car or the upper part of the room, making the person sitting in the chair feel cold. Particularly in the case of a chair installed inside a car, if the car is parked in a cold place, even if the heater is turned on, the interior of the car does not warm up quickly, making the chair you sit on feel cold.

Therefore, the purpose of this project is to create a chair that allows people to sit comfortably by making it possible to freely adjust the surface temperature of the chair f, and by making the chair at an appropriate temperature regardless of the temperature in the city or room. The purpose is to provide.

For this reason, the ungenerated IJJ uses a thermoelectric element as a heating/cooling device for the chair T.

Here, the heat element is an element that causes energy conversion between heat and electricity, and cools one side by passing a current, and heats the other side with the same amount of absolute value. be. Furthermore, in this mature element, the cooling surface and heating surface can be changed simply by reversing the direction of current.

[Means for solving problems] One aspect of the present invention is to solve the above-mentioned problems.

A heat transfer element with high thermal conductivity is placed near the seat of the chair,
The heat transfer body is thermally connected to one heat generating surface of the thermoelectric element, and the other heat generating surface of the thermoelectric element is thermally connected to a radiator.

[Example] Hereinafter, an example in which the present invention is applied to a car chair will be described with reference to illustrated examples.

The chair according to this embodiment is formed of a seat cushion lO as a seat, a seat back 11 erected upward from the rear upper part of the seat, and a headrest 12 provided on the seventh part of the seat back 11. There is. Further, an upper rail 14 serving as one of the seat slide rails is fixed to the lower part of the seat cushion 10 via a spacer 13.

The surface of such a seat cushion 10 is 1 (s 1
Although the cloth 15 is covered with cloth 15, +/+3 of the cloth 15 is provided with a flexible heat transfer body 21. Further, a thermoelectric element 20 is provided on the lower surface of this heat transfer body 21, and a heat radiator 22 is provided on the side of the opposite body heating body 21 of this thermoelectric element 20.

Similarly, a flexible heat transfer body 21 is disposed on the inner surface of the cloth 15 in the portion of the seat back 11 that comes into contact with the back, and a thermoelectric element 20 is disposed on the back surface of the heat transfer body 21. There are 11 heat sinks 22 in sequence.

The heat transfer body 21 is formed to be flexible so as to efficiently transmit the heat from the thermoelectric element 20 to the person sitting on the chair and not to make the seat uncomfortable. A: As an integral shape, for example, a net made of copper or aluminum can be considered.

Also, of the heat radiator 22, the seat cushion l.

By protruding from the lower part of the seat cushion 10, efficient heat exchange can be performed. Further, the heat sink 22 provided in the seat pack 11 is connected to the seat back 1.
It may be possible to make it protrude backward by 1, but the heat released by it will be multiplied by 1.
1 (Since this will affect the person sitting, in such a case, the heat radiator 22 may be installed inside the seat back 11.

Next, a description will be given of the use of the wood radiator 1 to cool the seat and back surface of a chair.

First, a switch (not shown) is turned on to cool the heat transfer body 21 side of the thermoelectric element 20 installed in the seat cushion 10.

Then, the heat cooled by the thermoelectric element 20 is transferred to the flexible heat transfer body 21, and as a result, the person sitting on the seat feels cold through the cloth 15 on the surface.

At the same time, the anti-body heating element 21 side of the thermoelectric element 20 is heated, but the heat generated on the anti-body heating element 21 side of the thermoelectric element 20 is radiated into the vehicle by the radiator 22.

Furthermore, at this time, if the thermoelectric element 20 of the seat back 11 is also energized, it will pass through the heat transfer body 21 and the cloth 15.

It can cool the back of the person sitting on it.

Conversely, when using the present invention to heat a chair, simply reverse the heating side and cooling side of the thermoelectric element 20.
That is, it is sufficient to simply reverse the current direction.

In the following description, the heat transfer body 21 is assumed to be a net-shaped body made of copper or aluminum, but it can also be formed into another shape, such as a plate-shape. Furthermore, other materials can also be used as long as they have good thermal conductivity. Furthermore, if it has the required rigidity and thermal conductivity, the heat transfer body 21 can be formed directly as a seat surface without providing the cloth 15.

In addition, in the embodiment, the radiator 22 provided on the seat cushion 10 was explained as being installed at the bottom of the seat cushion 10, and the radiator 22 provided on the seat back 11 was explained as being installed inside the seat back 11. It is also possible to provide the radiator 22 outside the vehicle and thermally connect the thermoelectric element 20 and the radiator 22 with a heat pipe (not shown).

Further, the shape of the heat radiator 22 is not limited to the illustrated example, and if necessary, a fan may be provided to improve the heat radiation effect from the heat radiator 22.

Further, although detailed illustration is omitted, a temperature sensor may be attached to the heat transfer body 21 located at the lower part of the seat surface, and the temperature of the chair may be controlled by this temperature sensor.

In the embodiment, the case where the thermoelectric element 20 is attached to the seat cushion 10 and the seat back 11 is explained as an example, but it may be attached only to the seat cushion 10.
Alternatively, it may be attached to the headrest 12 together with the seat cushion 10 and the seat back 11.

In this way, when the present invention is applied to a chair used in a car,
It keeps you cool in the hot summer and warm in the cold winter, allowing you to ride comfortably.

Furthermore, the present invention can be applied not only to chairs for automobiles, but also to chairs for airplanes, theaters, and halls.

When applied to chairs other than automobiles, especially in theaters or halls with high ceilings, warm air accumulates near the ceiling during heating in winter, making people inside feel cold. It is preventable.

Further, the shape of the chair does not necessarily have to be formed from a seat and a backrest as in the embodiment, but it can be formed from only a seat, or armrests can be attached.

[Effects of the Invention] As explained above, the present invention enables the surface temperature of the chair to be freely adjusted and maintains the chair where a person sits at an appropriate temperature regardless of the temperature inside the car or the room.
It is something you can sit on comfortably.
