Description

A heating element of having a part to heat-gathering}

The present invention relates to a planar heating element having a heat collecting part, and more particularly to prevent the temperature set in the control unit and the temperature generated in the heating element due to the heat collection phenomenon generated by placing a predetermined object on the upper surface of the planar heating element. It relates to a planar heating element having a heat collecting portion that can be.

In general, the surface heating element is hygienic and noiseless because it is easy to control the temperature and does not pollute the air, it is widely used in residential heating devices such as heating mats, heating pads, bed mattresses, thermal blankets, apartments and general houses.

In addition, heating devices in commercial buildings such as offices and shops, industrial heating devices in workshops, warehouses, barracks, agricultural equipment such as agricultural product drying systems in plastic houses, and various kinds of materials that can melt snow or prevent freezing of roads and parking lots. In addition to freeze protection devices, it is also used for leisure, winter, home appliances, anti-fog of mirrors and glass, health supplements, and livestock.

As described above, the basic configuration of the planar heating element used in various forms is as follows.

First, at least one pair of electrode members are formed in a longitudinal direction or a lateral direction of a heating element made of nichrome or carbon fiber, and a heating part having a structure in which an insulating member is laminated on upper and lower surfaces of the heating element, and the electrode member is electrically It is usually equipped with a separate control unit that supplies heat to generate heat and controls temperature.

1 is a perspective view showing a planar heating element conventionally used, Figure 2 is a cross-sectional view showing the main part of the planar heating element of FIG.

As shown in FIG. 1 and FIG. 2, the conventional planar heating element has a heating element 12 having a pair of electrode members 11 formed in a longitudinal direction or a horizontal direction, and an insulating member on upper and lower surfaces of the heating element 12. The heat generating unit 10 is laminated with a 13 and a control unit 20 for supplying power to the electrode member 11 of the heat generating unit 10 and controlling the temperature of the heat generating unit 10.

In addition, although the insulating layer 50 is formed on the bottom surface of the heat generating unit 10 for use as a mat, the insulating layer 50 may be omitted if necessary, and the surface heating element It can be changed in various ways depending on the intended use of.

When the planar heating element having such a configuration is set to a predetermined temperature in the control unit 20 and then supplied with power, the planar heating element has electrode members 11 formed on both sides of the heating unit 10 in accordance with the temperature, respectively. The current is sent, and the current of the electrode member 11 moves along the heating element to generate heat.

However, in the case of a planar heating element used for other purposes including the planar heating element for the mat having the above configuration, when a predetermined object is placed on a part of the upper surface of the heating element, the heating element portion that comes into contact with the object cannot emit heat to the outside. The heat collection phenomenon that maintains a temperature higher than the temperature set by the controller for a long time occurs.

This heat collection phenomenon keeps the heating element in a high temperature state, which causes the damage of the heating element and the risk of fire.For this reason, the damaged surface heating element cannot be reused, so all the heating elements must be replaced. It will cause damage.

In particular, when the surface heating element is used to dry crops such as rice, barley, wheat, corn, millet, buckwheat and cereals or red pepper, the temperature set by the control unit and the temperature of the grain placed on the upper surface of the heating element are different. The problem was that the quality of cereals or crops could be degraded because they could not maintain the proper temperature.

Therefore, in order to solve the above problems, there is a method of controlling the overall temperature of the heating element by evenly installing the bimetal on the planar heating element, but in this case, the cost of the overall product increases because the expensive bimetal is installed, and the manufacturing process The problem of complexity has arisen.

Therefore, the present invention is configured to solve the problems as described above, by preventing the heat collection phenomenon occurs in the planar heating element in a simple configuration without evenly installed expensive bimetal inside the planar heating element, the temperature and heating element set in the control unit It is an object of the present invention to provide a planar heating element having a heat collecting part capable of identifying the temperature of an object placed on the upper surface, and thus reducing the risk of damage and fire of the heating element as well as improving durability of the heating element.
