Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat heating device mounted on a toilet of a Western-style toilet.

[0002]

2. Description of the Related Art As a conventional heating device of this kind, for example, as shown in FIG. 20 is provided with an elastic cloth cover 21 on the surface thereof, and the cloth cover 21 is placed on the toilet seat 22 so that the heat generating knitted fabric 20 faces down (Japanese Utility Model Laid-Open No. 1-97800).
Also, as shown in FIG. 5, a heating element 2 formed by kneading curable silicone rubber and carbon powder inside the toilet seat cover 23.
4 and the outer periphery thereof is sealed with an electrical insulator (Japanese Utility Model Laid-Open No. 1-155900). In addition to the above, as shown in FIG. 6, there is a type in which a carbon surface heating element 26 is placed in a toilet seat cover 25, the periphery thereof is covered with a cushion material 27, and the outside thereof is covered with a PVC sheet 28.

[0003]

However, the structure shown in FIG. 4 described above has a disadvantage that the heat-resistant knitted fabric 20 is an extremely fine single wire, so that the bending resistance is low and the wire is easily broken. Further, since the heating knitted fabric 20 and the cloth cover 21 are integrated, when the cloth seat cover 21 is soiled by the toilet, the cleaning is performed with the heating knitted fabric 20 held. Disadvantageous in that it has large practical stress and lacks practical cleaning properties.

FIG. 5 shows a self-saturated temperature control based on the positive temperature coefficient of the resistance of the carbon powder, and has the disadvantage that the temperature control performance cannot be maintained, such as a change in the resistance value due to a repeated load. is there.

[0005] Further, since none of these devices shown in FIGS. 4 and 5 has a temperature controller for the heating element, the switches and the like are not properly disposed in practical use, and electrical and mechanical stresses are excessive. In addition, it relies on the self-control function of the heating element itself to control the temperature of the heating element, and it is unprotected against everyday abnormal use such as changes in the outside world, loads, bending, and overlapping, and is concerned about electric shock, fire, etc. There is a major drawback.

FIG. 6 shows that the electrical and mechanical stress on the carbon surface heating element 26 is buffered by the cushion material 27 and the PVC sheet 28. Is not performed, the surface heating element 26 is bent at the time of attaching / detaching operation of the surface heating element 26 at the time of washing the PVC sheet 28 or at the time of being left, so that there is a disadvantage that anxiety such as electric shock and fire cannot be eliminated. .

[0007]

Reference numeral 4 denotes a metal foil having good heat conductivity. A heat-fusible resin layer 3 is provided, and an adhesive layer 5 is provided on the back surface. The shape is generally the shape of the upper surface of the toilet seat, and is U-shaped with the front part cut. The cord-shaped heating element 2 is arranged in a meandering manner on the surface of the metal foil 4, and the resin layer 1 and the resin layer 3 are fused and fixed by hot pressing from the metal foil 4 side. The heat of the hot press is applied from the side of the metal foil 4, but the metal foil 4 is made of a metal such as aluminum and has a thickness of 20 mm.
If the thickness is about 80 microns, it is thin and the heat conduction is good, so there is little variation in the resin part to be heat-sealed and it is transmitted accurately, so only the necessary outer part is welded without damaging the inside of the cord heater. , Can be fixed securely. At this time, the temperature of the hot press is 180 to 230 ° C.
A good range is about 6 seconds.

When these are adhered to a hard and flexible resin sheet 6 having a certain thickness of about 0.3 to 1.5 mm, the resin sheet 6 has a certain bending inhibiting strength. In addition, local bending of the cord-like heating element 2 is suppressed.

[0021]

The present invention is configured as described above and has the following effects.

(1) Heat fusion to a thick base material is a difficult operation such as softening and damaging the entire cord-shaped heating element.
By using a thin metal foil of 80 microns, the heat conduction was good, and the cord-like heating element could be fixed accurately and firmly without damaging the inside. Further, in terms of performance, the metal foil made the entire heat distribution uniform as a surface heater. Also, in terms of performance, even if the cord-shaped heating elements should overlap, the metal foil is attached, so local overheating is unlikely to occur.
Safety against fire has improved.

(2) By bonding to a resin sheet having a certain thickness, local bending of the cord-like heating element can be suppressed, and mechanical load resistance and electrical safety have been improved.

(3) Due to the adhesion of the felt, the feeling of unevenness when a person is seated is eliminated, the feeling becomes soft, and the performance such as the heat retention of the heating element is improved.

(4) By covering with a heater case,
The infiltration of sewage and water was prevented, and the safety against electric shock etc. was improved.

(5) The detachability of the outer cover improves the cleanability such that the outer cover can be removed and washed when it becomes dirty with dirty water.

(6) By attaching the expandable band and the hook to the outer cover, the seat can be firmly fixed without being displaced to an existing toilet seat having a somewhat different shape, and the mechanical safety is improved.

(7) Since a detection line is provided on the cord-shaped heating element via the heat-sensitive resin layer, and the temperature is controlled by this signal, even if a temperature abnormality such as overheating occurs in any section of the heating line, the heat is generated. The quantity was controlled immediately and the electrical safety improved.
