[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The seat ventilation device according to the present invention relates to a seat back and seat ventilation device. In the seat of the seat, a urethane home is placed on a spring and covered with a seat made of vinyl resin, woven fabric, etc., so it will be cold until the surface is warmed by heating, and the seat does not breathe easily Therefore, it is a seat ventilation device that was devised in order to blow warm air or indoor air to the seat so that the user can sit comfortably.

Since the sheet ventilation device has a low air permeability on the surface of the sheet, it easily gets damp especially in summer and is cold in winter, so that it can be blown to a wet sheet to be dried. , The purpose is to blow warm air with a fan to warm a cold seat or to sit comfortably on that seat.

[Prior art]

 In the past, an indirect rug was placed between the seat and backrest of the seat and the human body to prevent the human body from directly touching the seat and prevent the seat from becoming stuffy. Placing a rug on the sheet does not completely prevent stuffiness. If the seat is cold, the rug does nothing to warm the seat.

The present invention is a seat ventilation device according to an improvement of 1993 Utility Model Registration Application No. 46839 (filed on Aug. 4, 1993) whose name was devised as “car seat intake / exhaust device”. Is. The car seat intake / exhaust device is provided with a forward / reverse rotatable motor, blower fan, and nichrome wire in the mounting frame provided in the mounting hole provided in the backrest, and the backrest and seat are arranged appropriately. A foot hose is provided in the fitting recess, and a large number of ventilation holes are opened in the surface, and one end where the foot hose is opened is provided in its mounting frame to allow warm air or cold air in the room to lie on the plane of the car seat. It is designed to blow off or suck cold air.

[0005]

[Problems to be Solved by the Invention] The problem to be solved by the present invention is to send the flow of cold air in the room to the cavity provided inside the seat by the rotation of the blower fan, which passes through the cavity. It is to make it blow out to the whole seat. In addition, the blower fan sends warm air to the flat surface of the cold seat to warm the seat, and when the seat gets wet due to sweat, the humidified seat is dried by the fan to make the seat comfortable. Is what you are trying to do.

[0006]

[Means for Solving the Problems] Hot or cold air blown by connecting a blower fan provided on a mounting frame provided on a backrest, a motor, and a nichrome wire, and electrically connecting to a power source with a power cord. Of the bellows tube is connected to the inner cavity of the hollow membrane provided in the mounting frame inside the seat backrest of the seat and the other outlet of the bellows tube is connected to the inner cavity of the seat to ventilate the air vent of the seat. The cavity and the seat through the cavity are provided with a plurality of ventilation holes for blowing warm air or cold air in the seat and the backrest, respectively, and the outlet of each ventilation hole is provided in the plane of the seat and the backrest. It is a venting device for the seat that is designed to be touched.

The seat and backrest of the seat are provided with a plurality of vents which communicate with their respective planes. A mounting frame is provided behind the backrest, and a blower fan, a forward / reverse rotatable motor that rotates the fan, and a nichrome wire that warms the air are provided inside the frame, and wired to each of the parts. To electrically connect to battery power. Attached to the backrest, the mounting frame has a hole in the front of the backrest that allows ventilation. A guard net should be provided behind the mounting frame. A cavity membrane is attached to the inside of the seat, and the inside of the seat and the inside of the seat are provided with a cavity formed by connecting one inlet of the bellows tube below the inside cavity of the cavity membrane and connecting the other outlet to the seat cavity. It is designed to be installed according to

[0008]

[Function] By connecting a power cord to the power source of the battery, the motor rotates the blower fan to blow warm air by the heat of the nichrome wire or cool air in the room into the cavity. Hot air or cold air was blown out from the vent of the sheet through the cavity. The motor allows the fan to rotate forward and backward, and can blow out hot air or cold air in the seat and the backrest of the seat as well as suck it in, so that the heat trapped in the seat is absorbed. , So that it can be put out behind the seat through the cavity. Nichrome wire is a heater that heats the air blown by a fan to make it warm. By circulating warm air or cold air in the room to the seat, the seat can be made comfortable and comfortable to sit in.
