Closet seat having electric heating means

Abstract

The invention relates to an electric heating toilet sea, which comprises main body and power element. Wherein, there are two layers of plastic films under the main body; the upper surface of upper plastic film is adhered with lower surface of main body; the lower surface of upper plastic film or the upper surface of lower plastic film is printed with print circuit connected to the power element; the wire width of printed circuit is 3-10mm; the printed circuit is bended into maze; the total length of wire is 3-10 times of the edge total length of main body; two layers of plastic film have no blank between them; the lower surface of upper plastic film and the upper surface of lower plastic film are adhered. The invention has large electric metal layer, and uniform radiated heat, with low cost.

Description

technical field [0001] The invention belongs to a toilet seat, in particular to a toilet seat with electric heating function. Background technique [0002] During the use of the toilet, its seat is in direct contact with the skin of the human body, which can cause discomfort to the human body in the cold winter. For this reason, people have set up electric heating elements on the toilet seat ring, and these electric heating elements mainly contain electric heating wire, coating formula electric heating film, adhesive formula electric heating film. [0003] There are three deficiencies in the toilet seat using the electric heating wire: first, the horizontal projected area of ​​the electric heating wire is small, which causes the heat generated by the electric heating wire to be highly concentrated in a small area, and the temperature unevenness of various parts of the seat ring is relatively serious. The temperature of the part of the heating wire is too high and the temper...

Problems solved by technology

[0003] There are three deficiencies in the toilet seat using the electric heating wire: first, the horizontal projected area of ​​the electric heating wire is small, which causes the heat generated by the electric heating wire to be highly concentrated in a small area, and the temperature unevenness of various parts of the seat ring is relatively serious. The temperature of the part of the heating wire is too high and the temperature of other parts is too low; the second is that the area of ​​the heating wire is small and the heat transfer is slow, and people usually turn on the power of the heating element when they start using the toilet, so when they first use it For a period of time, the heating degree of the seat ring is insufficient; the third is that the structure of fixing the heating wire to the seat ring body is relatively complicated, the installation is troublesome, and the waterproof and moisture-proof performance is poor. In the Chinese patent CN200420009580. wire fixed installation

[0004] However, the existing toilet seat using electrothermal film has a large area, thin thickness, and uniform heat distribution, but the production cost of the electrothermal film is high; in addition, the coating type electrothermal film has the following disadvantages: because the electrothermal film adopts a coating method or Electroplating is coated on the seat ring, so the manufacturing process is complicated, and the material requirements for the electric heating film are high, and the electric heating film is easy to fall off due to poor adhesion; as for the adhesive electric heating film, when the material of the metal electric heating layer is bonded to other materials, Its adhesion is poor, and the metal electric heating layer is connected together in a large area, and the electric heating film is in a state of frequent changes in cold and heat for a long time, so it is easy to cause the metal electric heating layer to peel off from the attachment part in pieces, affecting the normal operation of the electric heating film. use, or even cause the electric heating film to be scrapped
