Embodiment Construction

[0032] The manufacture method of small electric heating plate of the present invention, it comprises:

[0033] Cutting the antirust-treated metal plate into a square metal plate of a certain size, piercing at least two ventilation holes 11 on the metal plate cut into a square shape, and forming a junction box 12 and a channel 13 on one side of the metal plate, The four sides of the bending processing metal plate form the metal plate processing step 100 of the box-shaped plate 10; on the surface of the box-shaped plate 10, the paint containing the radiation material that can emit negative ions and far-infrared rays is coated to form the box of the far-infrared radiation layer 50. Template coating stage 200: a non-woven fabric 22 for preventing dust is arranged on the inner side of the box-shaped panel 10, and two sets of heating circuits C1 and C2 with at least two ceramic heating elements 20a-20f connected in series are formed, and then The ceramic heating element wiring stage...

Abstract

The present invention relates to a small size electric heating board and the manufacturing method. The small size electric heating board of the present invention is composed of a box shaped board being equipped with at least two air vents, a connecting box and a channel and coated with a far infrared ray emission coating; a natural carbon bed, which is formed in the box shaped board through compressing and is imbedded with at least two ceramic heating elements; an outer layer material stuck on the lower part laminated with the natural carbon bed without fabric fiber layer. The present invention makes the ceramic heating elements cast in an functional natural carbon bed, and provides an environment protective warming environment, a comfortable indoor living space and a sleeping environment through the environment protective positive function (the production of the far infrared ray and the anion, the antibiotic action, humidity adjusting, air purified, and the generating controlling of electromagnetic wave) of the natural charcoal, thus enhancing health. In particular, the present invention utilizes the natural carbon hot coal with a semi-permanent environmental protection positive function, and lengthens the service life of the electric heating board for twice.

Description

technical field [0001] The invention relates to a small electric heating plate and a manufacturing method thereof, in particular to a small electric heating plate using natural charcoal as a heat medium and a manufacturing method thereof. Background technique [0002] Common heating panels (panels) are generally formed by arranging the heating wires (2) in a U-shape on the heat insulating material (1) and then stacking them with functional backing plates, as shown in Figure 1. In order to maintain the resistance of the heating wire (2), it is necessary to make the heating plate almost the same as the size of the plywood, that is, at least one side in the length and width of the heating plate will be greater than 1 meter. If a small electric heating plate is manufactured, in order to maintain a certain amount of resistance of the small electric heating plate, it is necessary to reduce the spacing between the heating wires arranged in a U shape, so as to lengthen the length of...
