The present invention relates to a heat generating block including a heat generating portion therein.

In the winter, when the snow comes, the snow is frozen and melted. In the course of repeating the ice sheet, the risk of safety accidents increases. Especially, children, people with disabilities and the elderly are at high risk of accidents when walking. Conventionally, in order to dissolve snow, a hot line is laid, and concrete is poured thereon to provide a snow removal apparatus.

However, the construction cost is high, and only the place where the cable is placed is heated, so that the snow removal performance is not good and the trouble can not be repaired.

In order to solve such a problem, a snow block as disclosed in Japanese Patent Registration No. 10-1101624 has been proposed.

However, the heat transfer efficiency is not excellent due to being surrounded by thick rubber, and there is a risk of fire due to overheating or short circuit. In addition, environmental pollution may occur in the production of rubber products, and odor is generated, which is not environmentally friendly.

On the other hand, for the heating of the floor in winter, a heating block using hot water or electricity is used. When a block or the like installed in a floor heating uses electricity, generally a heating cable is built in, and the material is surrounded by a material having low heat conduction efficiency. Therefore, it has limitations in that even heat and heating are difficult, and there is a risk of fire when an overcurrent is applied or a short circuit occurs.

In order to solve the above problems, it is an object of the present invention to provide a heat generating block which is heated evenly over the entire bottom surface to increase the heating efficiency.

It is another object of the present invention to provide a heat generating block capable of preventing a fire from occurring inside.

According to an aspect of the present invention, there is provided a heat generating block including: a housing including at least a part of a metal; A heating unit positioned inside the housing; And a filler filling the inside of the housing, wherein the heat generating portion is heatable by electricity.

The filler may be a urethane foam and may be provided to block the inflow of air into the heat generating portion.

Wherein the heating unit includes: a planar heating element including carbon and generating heat; And an insulating and waterproof sheet surrounding the outside of the planar heating element.

The housing includes a heating plate for transmitting heat of the heat generating unit to the outside; A side plate positioned at an edge of the heating plate; An edge plate extending inward from an end of the side plate opposite to the heating plate and having an opening formed at the center thereof; And a back plate covering the edge plate and the opening.

The heating plate, the side plate, and the edge plate may be integrally formed, and the white plate may be coupled to the opposite side of the heating plate so as to cover the edge plate and the white plate.

When the heat-generating block according to the present invention is installed outdoors, it is possible to secure the safety of the pedestrian because the snow is not automatically melted and accumulated.

In addition, safety is further enhanced when a means capable of preventing slippage of a pedestrian is provided and means capable of preventing the heat generating heat generating block itself from slipping on the floor are provided.

In addition, even if heat is generated using electricity, the possibility of a fire occurring due to a short circuit or the like is blocked from the source, and the stability is further enhanced.

Therefore, either the upper end or the lower end of the side plate contacts the heating plate 11, and the other side contacts the edge plate 13. [ An opening 14 is formed at the center of the edge plate 13. [

Therefore, the heat generating plate 11, the side plate 12 and the edge plate 13 can be integrally formed. After one metal plate is cut into a predetermined shape, the heat generating plate 11, the side plates 12 And an edge plate 13, as shown in Fig.

The white board 15 is located on the opposite side of the heating plate 11 so as to cover the edge plate 13 and the opening 14. [ Therefore, it has a larger size and shape than the opening portion 14. More specifically, the back plate 15 has substantially the same shape and size as the heating plate 11, and has a thin thickness. The back plate 15 may be made of metal. However, the present invention is not limited thereto, and there are no restrictions on the material.

Therefore, in the housing 10, the heating face and the side face are shielded by the heating plate 11 and the side plate 12, respectively. In the state where only the edge is shielded by the edge plate 13 on the opposite side of the heating face, And the opening 14 is shielded by the cover 15.
