Description

ELECTRICAL HEATING PANEL

The present invention relates to a wood heat transfer panel, and more particularly, to a wood heat transfer panel which is capable of maintaining a stable assembled state without deforming the entire outer shape even if distortion of the wood occurs due to shrinkage and expansion phenomenon, To a wood heat transfer panel that maximizes the fomenting effect while emitting.

Generally, a heat transfer panel used for a dry half-bath, a sauna or an electrothermal bed in which air is heated is used for heating the electric heating line. Since most of the heating panel performs a heating operation only by the heat generated from the heating line, There is a problem that the energy consumption efficiency is extremely low due to the excessive consumption of electric power.

Recently, as the improvement of the residential culture and the interest in the so-called well-being products have been increased, it is also possible to add far-infrared rays and anions, which are beneficial to the human body through the use of loess, Heat transfer panels that combine functionalities such as heat, pressure, and effects have been proposed and received.

On the other hand, evergreen arborescent trees such as unshiu woods and cedar trees have terpenes which have a beneficial effect on human bodies such as sterilization, antibacterial, soothing, deodorization, relieving stress, increasing immune function of allergy and skin diseases, (Phytoncide), which is a main component of the organic compound of the present invention, is contained in a large amount, and a heat transfer panel using the same has been proposed.

For example, as shown in FIG. 1, the 'environment-friendly unbleached wood warm fomentation mat' disclosed in Korean Patent Registration No. 10-1225835 includes a square frame 1 having a concave (not shown) (Not shown) of an outer frame to be inserted into the grooves of the square frame 1 and a lower plate 3 which is provided between the upper plate 2 and the lower plate 3 and is connected to a controller 7 formed on the bottom surfaces of the copper sheet 6 and the heat generating sheet 5 provided on the upper surface of the heat generating sheet 5 and the heat insulating sheet 4 ).

In the process of shrinking the inside of the square frame 1, the upper and lower plates 2 and 3 due to the drying process, or absorbing the external moisture to swell, This causes a problem in that the shape of the frame 1 and the assembly of the upper and lower plates 2 and 3 is distorted and deformed.

In addition, since it takes a time of about 2 to 3 years to ideally dry the wood, it is inevitable that a minute shrinkage phenomenon occurs while the moisture escapes mostly after the processing. However, in the conventional heat transfer panel, It is possible to effectively prevent the occurrence of a gap between the upper plate 2 and the lower plate 3 or the deformation of the entire shape of the rectangular frame 1 by merely fitting and fixing the lower plate 2 and the lower plate 3 into the groove of the rectangular frame 1. [ There are considerable limitations due to its structural characteristics.

In addition, since the heat generating sheet 5 of the conventional heat transfer panel is made of a heat ray film such as a surface heating element, it is very vulnerable to the risk of short-circuiting or short-circuiting with each other due to external force. Therefore, in order to maintain a constant temperature, it is necessary to continuously supply electricity. As a result, the power consumption is excessively high, resulting in an extremely low energy consumption efficiency.

In addition, the heat-generating sheet 5 generates harmful electromagnetic waves to the human body during the heat generation process, and thus there is a high possibility that the health of the user may be adversely affected. This is because of the pattern and consumption tendency of modern people who prefer well- Which is a cause of avoiding the use of the heat transfer panel, and adversely affects the merchantability of the article adopting the heat transfer panel.
