Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair having an air outlet for cooling and heating.

[0002]

2. Description of the Related Art Conventional chairs are rarely provided with a heating / cooling means in the chair itself, and an example in which an electric heater is provided under the chair for heating is found only in a railroad vehicle. Very few examples have the means.

[0003]

As described above, since the conventional chair is not provided with the cooling means, when the cooling air blown out from the outlet of the vehicle or the like hits the body, that portion feels comfortable. The part where the body and the chair are in close contact,
That is, since there is no ventilation on the back and legs and the body temperature cannot be dissipated, it is hot and there is a strong discomfort due to an increase in humidity due to sweating. Occupants of automobiles are obliged to wear seat belts, and their body remains in close contact with the chair for a long time, and the discomfort during the summer is unbearable. Also, it is not pleasant to be restrained with a seat belt on a cold chair at the start of winter.

An object of the present invention is to provide a chair that solves the above problems and provides a comfortable environment with a high air conditioning effect.

[0005]

The object is to have a plate-like lower plate member located at the lower part, a plurality of coil springs arranged on the lower plate member, and an opening portion arranged on the plurality of coil springs. A plate-shaped upper plate member, a film that encloses the upper plate member, the coil spring, and the lower plate member, has an opening at the same position as the opening of the upper plate member, and is airtight and stretchable, and is arranged on the film. Then, a cushioning material made of an elastic material having an opening at the same position as the opening of the membrane, a skin having air permeability arranged on the cushioning material, and air for cooling and heating provided on the side surface of the membrane. It is achieved by providing a ventilation pipe for sucking the supply or atmosphere.

[0006]

According to the above construction, since the air for heating and cooling blows out from the outlet provided in the chair, it reaches the portion where the air for cooling and heating did not reach, so that the cooling and heating is sufficiently performed and the atmosphere is sucked. By doing so, dehumidification is also performed, and a comfortable living environment with a high air conditioning effect can be obtained.

[0007]

Embodiments of the present invention will be described with reference to the drawings.

First, the overall structure of the chair of this embodiment will be described.

FIG. 1 is a partial vertical cross-sectional view of a chair provided with air outlets for cooling and heating air according to this embodiment. FIG. 2 shows a plan view of the cushioning material of FIG. 1 as seen from above.

An upper plate member 3 having a plate-like lower plate member 1 on which a leg member of a chair is illustrated, a plurality of coil springs 2 are arranged on the lower plate member 1, and openings are formed on the plurality of coil springs 2. , And the membrane 4 having an opening at the same position as the opening of the upper plate 3 and having airtightness and elasticity surrounds the lower plate 1, the coil spring 2, and the upper plate 3 as a whole. A cushioning material 5 made of an elastic material having an opening at the same position as the opening of the membrane 4 is arranged on the membrane 4.
Is usually used for chairs and is made of elastic and breathable material such as urethane foam and fiber.

Further, a skin 6 is arranged on the cushioning material 5, and the skin 6 can be made of breathable twill fiber, mesh plastic, or cowhide or vinyl leather with small holes. A ventilation pipe 7 is provided on the side surface of the membrane 4 for supplying air for cooling and heating to the interior of the membrane 4 or sucking the atmosphere. These structures are suitable for the bottom part of the chair because of the structure using the coil spring 2, but the same effect can be obtained even if they are provided on the back part and the lateral part.

Next, the operation of this embodiment will be described.

A pipe from a supply source of cooling / heating air is connected to a ventilation pipe 7 provided on the side surface of the membrane 4 to supply cooling / heating air having a pressure that overcomes the pressure loss of the blowing system. In the case of heating, a heater is provided between the blower and the ventilation pipe 7 to supply pressurized heating air to the ventilation pipe 7. Further, when a heating element is incorporated inside the membrane 4, only air is supplied from the blower to heat the heating element. In the case of cooling, a cooler is provided between the blower and the ventilation pipe 7, and pressurized cooling air is supplied to the ventilation pipe 7.
Supply to. Further, the air may be sucked and pressurized by a blower from the cool air outlet of the cooler and supplied to the ventilation pipe 7. In the case of a vehicle such as an automobile, since the air outlet of the air conditioner is arranged near the chair, the air for cooling is taken in from the air outlet, and if necessary, sucked and pressurized by a blower and supplied to the ventilation pipe 7. Depending on the type of vehicle, the air outlet of the air conditioner is arranged not only in the dashboard of the front seat but also in the rear seat, so it is possible to provide a branch for supplying the ventilation pipe 7 in the middle of the duct. . If a damper is provided at the outlet of the air conditioner that takes in the cooling air, the cooling air from the outlet of the cooling and heating air can be controlled. Since the air conditioner may not be used in some cases, it is desirable to provide another cooling air source.

The cooling air supplied to the ventilation pipe 7 is dispersed in the membrane 4 and blows out through the upper plate 3, the opening of the cushioning material 5, and the skin 6, so that a comfortable temperature and humidity can be obtained around the chair. Maintain and enhance the air conditioning effect. Further, not only the cooling air is blown out from the blowout port but also the atmosphere is sucked in, whereby the humidity due to perspiration or the like can be removed and the humidity can be lowered.

As described above, according to this embodiment, it is possible to maintain a comfortable temperature by blowing cold air or warm air from the air outlet for cooling and heating air provided at the bottom, back and side of the chair. . In addition, by inhaling the atmosphere from the air outlet, it is possible to create a comfortable state by removing environmental humidity due to perspiration and the like. The chair of this embodiment has a remarkable effect in a vehicle in which the body is restrained for a long time, such as an automobile, a railroad, or an aircraft.

[0016]

According to the present invention, it is possible to enhance the air conditioning effect by blowing out cool air and warm air from the air outlet for cooling and heating provided in the chair, and to provide a comfortable living environment for the chair user. I can. Further, the effect of preventing the rise of humidity due to perspiration or the like can be obtained by inhaling the atmosphere containing moisture from the outlet.
