FOLDABLE ELECTRIC HEATER (FOLDABLE ELECTRIC HEATER)

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding type heater which is portable and easy to store, and more particularly, to a folding type heating device which is foldable in a longitudinal direction, The present invention relates to a folding type heater which is easy to carry and store and which is easy to carry and store.

Generally, a heating heater used for protecting the body from the cold by raising the indoor temperature in the winter is an electric heater, a mixed heater, a steam heater, or the like depending on the purpose and configuration.

Among them, the electric heater radiates heat generated by the supplied power source directly, so the heating effect can be obtained in a short time, and it is possible to miniaturize the electric heater, so that it is light in weight and easy to move, easy to install and use, Because it is low, it is widely used for factories, small offices or households.

In recent years, the amount of nano carbon heater using carbon fiber as a heating element is increasing. The nano carbon heater is a heater using a carbon heating element made by twisting about 20,000 strands of carbon fibers and performing heat treatment at a temperature of about 1,800 ° C, It retains the chemical superiority of carbon, and is excellent in acid resistance and alkali resistance, so that there is little worry about corrosion even when used for a long time, and electrical stability is the most important as a heat conductor. Especially, it is known that it is very good for health and skin as well as the effect of heating due to the charcoal component emitting a large amount of far-infrared rays which is well-known in the well-being age. The nano carbon heater is heated after about 3 seconds after the operation, It has high emissivity and thermal efficiency, it has energy saving effect up to 36% compared to ordinary nichrome hot wire. It does not emit electromagnetic waves and has less glare unlike halogen lamp.

The nano-carbon heater heats air through the heating element to form hot air after flowing outside cool air, and discharges the generated hot air to the outside. However, in the conventional nano-carbon heater, the heating element is disposed outside the heater There is a problem that the heating effect can not be obtained due to a short time for the cold air introduced by the heating element to be heated by the heating element and the temperature of the hot air discharged to the outside is low.

On the other hand, small heaters are divided into electric heaters, oil heaters and gas heaters depending on the fuel used.

The electric heater increases the temperature of the room in a short time using electricity, has no odor, and has no harmful gas component compared to an oil or gas heater. However, in the case of an electric hot air fan, It has to be replaced and the air becomes dry.

The oil heater has a high thermal efficiency and is effective for heating a large area. However, since the fuel cost is high and the oxygen consumption is larger than that of the electric heater, the oil heater must be frequently ventilated, the harmful component gas is generated, and the risk of fire is high. have.

The gas heater has a high thermal efficiency and low fuel cost. However, since the gas heater is less convenient to use than the electric heater and consumes more oxygen than the electric heater, the gas heater must be frequently ventilated and the harmful component gas is generated. have.

As shown in FIG. 1, the utility model No. 455553 (Registered on May 5, 2011.) of the Republic of Korea has a body 10, a fan 60, a center tube 80, a heat transfer member 30, (20).

The upper portion of the heat transfer member 30 is installed to penetrate the inside of the reflector and the center tube to heat air temporarily stored in the center tube It comprises a heating element consisting of carbon (20).

As described above, according to the related art, the external air flows into the upper part by the fan, and the moved air is heated through the carbon heating element and then discharged to the outside. At the same time, the heat of the carbon heating element is radiated through the reflection plate, Warm the surroundings.

However, the conventional central tube and the reflection plate are separately formed and then installed. In particular, the reflection plate is coupled adjacently so that a plurality of plates face each other, and a surface facing each direction is curved concavely, And a plurality of metal plates are curvedly formed and integrally formed by welding or the like, so that the manufacturing process is complicated and the manufacturing defect rate is high.

In addition, there is a problem that the direction of the heat discharged through the reflection plate is discharged in multiple directions and the heat is discharged even in a direction in which the heat is not required to be discharged. In other words, when the heater of the prior art is disposed close to the wall surface, There is a risk of fire by heat.

In addition, the shape of the reflector is formed such that the shape of the flat end face is triangular, and the carbon heating element is coupled to both sides of the carbon heating body so as to protrude forward, so that the heat is discharged only toward the front side, thereby reducing the risk of fire. There is a problem that the range of heating becomes narrow because there is no heat.

On the other hand, as described in the related art, the conventional heat-generating heater is typically formed into a regular shape having a predetermined size in the mouth shape, which is difficult to store. That is, a heating heater or a portable or small-sized radiator is used for heating the interior when the internal temperature falls below a predetermined temperature as in winter, and is not necessary when the temperature exceeds a certain temperature such as summer. do. In this case, since the conventional heat-generating heater is formed in a regular volume, there is a problem that a storage space is required.

Recently, there is a case where a heater heater is picked up because it enjoys leisure such as an auto camping even in the winter. In this case, there is a problem that the space occupied by the vehicle is occupied by the standardized volume. That is, the conventional heating heater or the small heater has a problem that the portability and storage property are poor and the competitiveness of the product is weak.
