Description

Heating chair with air layer {Heating chair}

The present invention relates to a warm chair having an air layer, and more particularly, to an air chamber formed by a plurality of rows inside a heating plate to reduce the total weight and increase the cross-sectional area of the heating plate, At the same time, it is possible to reduce the temperature drop of the heating element even in a low-temperature external environment, thereby saving the electric consumption (W) in preparation for the use time, and by embedding the carbon fiber heating element inside the heating plate, The present invention also relates to a heating chair having a heating plate having a carbon fiber heating body and an air layer excellent in dustproofness and moisture-proof property.

Generally, conventional electric heaters use 220V or 110V in the home, and resistive wires such as copper wire or nichrome wire are arranged and fixed in a zigzag as a heating element, and heat generated by flowing electric current is used.

However, the electric heater according to the above-described prior art can be manufactured only in the form of a long plate because of a structural problem, and it is difficult to manufacture the electric heater in a specific form for special use. In addition, in the conventional electric heater, resistance wire such as copper wire or nichrome wire is liable to be broken when used for a long period of time. To repair the electric heater, it is inconvenient to disassemble the product and reconnect or replace the disconnected part.

In addition, an electric heater using a resistance wire such as a copper wire or a nichrome wire according to the related art may cause a fire or an image problem due to overheating, and also has a problem that a human body is adversely affected by the generation of electromagnetic waves.

On the other hand, a heater using carbon fiber has been developed and used to solve the problems of the prior art. Since the heater using such a carbon fiber has a smaller heat capacity than that of a heater using a metal heating element and has excellent rising and falling temperature characteristics and also has excellent durability at high temperature in a non-oxidizing atmosphere, And so on.

The carbon (carbon) constituting the above-mentioned carbon fiber is mainly composed of an inorganic or organic graphite structure. Examples of the carbon fiber include a carbon fiber made of yarn, a powder made of powder, a carbon felt made of cotton and a solidified carbon rod It can be divided into two. Such carbon is stronger than iron and lighter than aluminum because of its high elasticity and strength.

The carbon fiber, which is one type of carbon as described above, is classified into a polyacrylonitrile (PAN), a pitch and a rayon based on the raw materials, and most of the PAN and rayon are included.

Among the above-mentioned carbon fibers, PAN-based carbon fibers are produced by firing PAN at a temperature of 1,000 to 2,000 DEG C or higher under inert gas. On the other hand, in the case of the pitch system, the pitch from the coal is converted to fibrous material, and then the process is completed through almost the same process as that of the PAN system. However, since it is low in comparison with the PAN system, it is widely used as a thermal insulation material or a reinforcing material.

On the other hand, the conventional surface heating element using carbon fiber has a problem that since the carbon fiber heating wire is directly woven on the fabric, there is a problem that the heat generating effect is not largely exhibited, and there is a risk of fire.

In addition, there is a problem that disconnection of the carbon fiber can easily occur in the planar heating element using the carbon fiber according to the related art as described above.

In addition, the heating element using the carbon fiber as described above has many difficulties in applying to a chair such as a stoppage or a park.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide an air layer formed in a plurality of rows inside a heat generating plate to reduce the total weight, And also to reduce the temperature drop of the heating element even in an external environment of a low temperature, thereby saving the electric consumption (W) in preparation for the use time.
