Description

Voltage variable heating device {Apparatus for heating using voltage variable}

The present invention relates to a voltage variable heating device, and more particularly, to a voltage variable heating device configured to output a variable output voltage of output power input from a battery device.

In winter, electric mats and electric cushions are widely used for quick and easy heating. In general, in a conventional mat or cushion using electricity, a resistance wire such as a copper wire or a nichrome wire is arranged in a zigzag as a heating element, and it is common to produce heat by supplying an electric current thereto.

However, in the conventional electric mat or cushion, the copper wire or nichrome wire is easily cut off when used for a long time, and there is a risk of burns or fire due to overheating. In addition, since electromagnetic waves are generated, it may adversely affect the user.

In addition, since 220V or 110V is used, there is a problem in that it is not suitable to carry current because it cannot receive current in a place without an outlet.

It has been devised to solve the above problems, and a mat or cushion using carbon fiber as a heating element is used. A heating element using carbon fiber has advantages in that it has a small heat capacity, excellent rise and fall temperature characteristics, and does not emit electromagnetic waves, as compared to a heating element using copper wire or nichrome wire.

The carbon constituting the carbon fiber mainly has an inorganic or organic graphite structure, and there are carbon fibers made of yarn, powder made of powder, carbon felt made like cotton, and solidified carbon rods.

However, in the case of using a portable battery device as a power source, the heating cushion of the prior art cannot vary the output voltage of the output power output from the portable battery device, so that the heating can be performed using a voltage capable of achieving maximum thermal efficiency. There is a problem that it cannot.
