Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation sheet which is mainly attached to the surface of an automobile seat or seat or a mattress or a cushion, and is particularly used for a ventilation seat. The present invention relates to a temperature adjusting sheet device suitable for controlling the temperature during use by blowing cold air or warm air from the inside to the surface of a seat.

[0002]

2. Description of the Related Art When using a car seat or a chair in close contact with the back or waist, even if the seat or chair is in contact with the back or waist even in a room where an air conditioner or cooler is used. Part may sweat. This is because materials such as seats and chairs are warmed by body temperature, and this temperature is accumulated in the seats and the like to raise the temperature of the close contact portion. Therefore, conventionally, the surface of a seat or a chair is covered with a material having the best breathability so that the body temperature is not trapped in the seat.

[0003]

However, even if a material having good air permeability is used for the surface of a sheet or the like, there is a limit to the air permeability depending on the material, and when the temperature or humidity of the operating environment is particularly high, However, when the user's body temperature is high, there is still the inconvenience of sweating.

In addition, even when a seat or the like is used in cold weather, it is desired that the seat be as warm as possible rather than sitting on the surface of a cold seat.

Therefore, the present invention was created in order to solve the above-mentioned problems, and from the inside of the sheet to the surface of the sheet,
It is an object of the present invention to provide a temperature adjustment sheet device capable of forcibly blowing cold air or hot air to control the operating temperature.

[0006]

In order to achieve the above object, the first means of the present invention is a bag-like member having a front surface portion 1A and a back surface portion 1B, and the front surface portion 1A is partially or entirely covered. A cover body 1 provided with a ventilation hole 1a and a back surface portion 1B of the cover body 1 which is mounted inside the cover body 1 and a front surface portion 1A
Ventilation core body 2 having a large number of ventilation holes 2A penetrating in the direction
And a blower 3 that blows air inside the cover body 1, and forms a gap between the back surface portion 1B of the cover body 1 and the ventilation core body 2 for blowing the wind of the blower 3. This is because a plurality of ventilation protrusions 2B are provided.

Further, the ventilation core 2 according to the second means is made of a flexible sheet, and the ventilation holes 2A are opened between the ventilation protrusions 2B projecting from the back surface of the ventilation core 2 for ventilation. The surface portion of the core body 2 is provided with a support protrusion 2C for supporting the surface portion 1A.

Further, the blower 3 of the third means has a surface portion 1
A means for solving the problem is to detachably attach to the blower port 4 provided at the joining portion of A and the back surface portion 1.

[0009]

According to the first means of the present invention, the wind blown from the blower 3 passes through the ventilation hole 2A of the ventilation core 2 from between the back surface portion 1B of the cover body 1 and the ventilation core 2 to cover the air. It is forcibly discharged from the vent hole 1a of the surface portion 1A of the body 1.

In the second means, the wind that has passed through the air holes 2A from the gap between the ventilation projections 2B passes through the periphery of the support projections 2C and is then discharged.

Further, in the third means, the blower 3 is detachably attached to the blower port 4.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings. The main structure of the seat device of the present invention comprises a cover body 1, a ventilation core body 2 and a blower 3.

The cover body 1 has a bag shape having a front surface portion 1A and a back surface portion 1B. Then, the surface portion 1A is provided with a ventilation hole 1a in a part or the whole surface (see FIG. 1).
The surface portion 1A in the illustrated example is formed in a mesh shape and the ventilation holes 1a are provided on the entire surface of the surface portion 1A. Also, the back surface part 1
B is preferably made of a material having a high sealing property as much as possible, and is mounted so that the ventilation core 2 is wrapped between the front surface portion 1A and the rear surface portion 1B.

The ventilation core body 2 is mounted inside the cover body 1 and has a large number of ventilation holes 2A which penetrate the back surface portion 1B of the cover body 1 in the direction of the front surface portion 1A. The back surface 1B of the ventilation core 2 is provided with a plurality of ventilation projections 2B on the crocodile, and a gap is formed between the back surface 1B of the cover body 1 and the ventilation core 2 so that the air from the blower 3 can be blown. . At this time, the ventilation core body 2 has a flexible sheet shape, and the ventilation holes 2A are opened between the ventilation protrusions 2B that are projected at equal intervals, and the surface portion of the ventilation core body 2 is formed into a crocodile surface. A support protrusion 2C for supporting 1A is provided (see FIGS. 1 and 2). The ventilation protrusion 2B is formed higher than the support protrusion 2C. This is because the ventilation protrusions 2B blow the air from the alligator blower 3 to every corner. Further, the support protrusion 2C is mainly for preventing the vent hole 2A from being blocked by the body of the user, and the air is blown to the entire surface portion 1A from the gap formed by the support protrusion 2C. The material of the ventilation core 2 is planned to be made of soft PVC, but other materials may be used, and a hard material may be used instead of the flexible material. It is also possible to form the ventilation projections 2B of the ventilation core 2 on the cover body 1 by the crocodile. By providing a plurality of magnets 5 on the support protrusion 2C, it can be used as a health device that stimulates the independent nervous system of each part of the body to promote blood circulation.

The blower 3 blows air into the inside of the cover body 1, and the blower 3 is detachably attached to a blower port 4 provided at a joint portion between the front surface portion 1A and the rear surface portion 1. The blower 3 may use an AC power supply or a DC power supply in addition to using a battery, and when used for a vehicle seat, it is possible to use a cigarette lighter as a power source.
The blower 3 shown comprises a fan 3A and a ventilation port 3B, and blows the outside air of the blower 3 into the inside of the cover body 1. According to this type of blower 3, for example,
It is possible to blow cold air cooled by a cooler or an air conditioner or warm air heated by a heater to the inside of the cover body 1. Although not shown, the blower 3 may be provided with a heater or the like.

[0016]

The present invention achieves the original object by being configured as described above.

That is, according to claim 1, it becomes possible to control the operating temperature by forcibly blowing cold air or warm air from the inside of the sheet to the surface of the sheet. As a result, comfortable use is possible even when the temperature and humidity of the environment of use are particularly high or the body temperature of the user is high. Moreover, even in use in cold weather, warm air is blown out instantly, so that a warm sheet or the like can be used from the beginning.

Further, according to the second and third aspects, since the structure of the seat device of the present invention can be simplified, the seat device has a high durability and can be provided at a low cost.

As described above, according to the present invention, cold air or warm air can be forcibly blown from the inside of the sheet to the surface of the sheet to control the operating temperature, which enables always comfortable use. It has various beneficial effects.
