Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heated toilet seat that is mounted and fixed on a Western-style toilet, or a heated toilet seat that is used in combination with a washing and drying device.

[0002]

2. Description of the Related Art A conventional heating toilet seat of this type has a structure shown in FIGS. First, the heating toilet seat
As shown in FIG. 3, it is composed of a main body 5 mounted on the toilet bowl 1 and having a control unit 4 and the like, a toilet lid 2 and a toilet seat portion 3. The toilet lid 2 and the toilet seat portion 3 have a rotating shaft 6 Is connected to the mounting hole 7 of the main body 5 so as to be pivotally attached rotatably.

The detailed structure of the toilet seat 3 is shown in FIG. The heater wire 8 is welded to a flat horseshoe-shaped or substantially O-shaped film 9, and a temperature fuse or thermostat overheat protector 10 is connected with an electric wire 11 such as a lead wire, and then covered with a vinyl chloride tube 12 to cover both ends. To form a heater unit 14 in which a temperature detection sensor 13 such as a thermistor is arranged and fixed. Then, the film 9 is formed on the back surface of the body 15 forming the surface of the toilet seat 3 formed of synthetic resin.
An adhesive (not shown) is attached to the back surface of the sticker, the electric wire 11 is passed through the rotary shaft 6, and the back plate 16 forming the back surface of the toilet seat portion 3 formed of synthetic resin is joined to the body 15. Welding by ultrasonic welding or heat welding.
Is bonded to the back plate 16.

Next, as shown in FIG. 5, the internal structure of the rotary shaft 6 is a through hole, through which an electric wire 11 is passed and connected to the control section 4 of the body 15.

In the above structure, the signal from the control section 4 in the body 15 is transmitted through the through hole in the rotating shaft 6 to the electric wire 11
Since it is transmitted to the toilet seat part 3 through the upper and lower sides of the toilet seat part 3 without any hindrance, the electric wire 11 for electrically connecting the body 15 and the toilet seat part 3 is passed through the through hole in the rotating shaft 6, The electric wire 11 is not exposed to the outside at all, the appearance is neat, and it is easy to clean.
(For example, JP-A-58-157420)

[0006]

However, in the conventional structure as described above, since the rotary shaft 6 is cylindrical, urine, sewage and detergent enter through the rotary shaft 6 and the heater wire 8 in the toilet seat portion 3 is invaded. And the temperature rise sensor 10 and the electric wire 11 and the temperature detection sensor 13 may be attached to cause a malfunction due to corrosion and the like. Since it has a cylindrical shape, there is a problem in strength, and the rotating shaft 6 may be broken.

The present invention solves the above-mentioned conventional problems. The electric wire 11 connected to the heater wire 8 in the toilet seat portion 3, the overheat protector 10 and the temperature detection sensor 13 is provided in the rotary shaft 6. It is intended to prevent malfunction of the heated toilet seat and to improve the strength of the rotating shaft 6 of the toilet seat portion 3 even if they are arranged through.

[0008]

In order to achieve the above object, a heating toilet seat according to the present invention has a toilet seat portion having a rotary shaft on a rear side surface thereof and a heater unit incorporated therein, and facing the rotary shaft of the toilet seat portion. A main body having a mounting hole and a control section, and an electric wire for electrically connecting the heater unit and the control section, and connecting the rotating shaft of the toilet seat section and the mounting hole of the main body to each other. The toilet seat portion is rotatably pivotally mounted, the electric wire is passed through the rotating shaft of the toilet seat portion, and the rotating shaft of the toilet seat portion is filled with resin.

[0009]

According to the present invention, with the above-described structure, the rotary shaft through which the electric wire is passed is sealed to prevent invasion of urine, sewage and detergent, and further improve the strength of the rotary shaft.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a heated toilet seat according to the present invention will be described below with reference to the drawings of FIGS. The same components as those of the conventional example are designated by the same reference numerals.

First, as shown in FIG. 3, the heated toilet seat comprises a main body 5 which is placed on the toilet 1 and has a control section 4 and the like, a toilet lid 2 and a toilet seat section 3. The toilet seat 3 is configured so as to be pivotally attached by connecting the rotating shaft 6 to the mounting hole 7 of the main body 5.

Next, as shown in FIG. 1, the internal structure of the rotary shaft 6 is insert-molded through the electric wire 11 so that the inside thereof is filled with the synthetic resin.

Next, a detailed structure of the toilet seat 3 is shown in FIG. The heater wire 8 is welded to a flat horseshoe-shaped or substantially O-shaped film 9, and a temperature fuse or thermostat overheat protector 10 is connected with an electric wire 11 such as a lead wire, and then covered with a vinyl chloride tube 12 to cover both ends. To form a heater unit 14 in which a temperature detection sensor 13 such as a thermistor is arranged and fixed. Then, the electric wire 11 connected from the heater unit 14 is preliminarily passed through, and the rotary shaft 6 insert-molded is set between the molds to perform molding.
The back surface of the heater unit 14 is attached to the back surface of the body 15, and the back plate 16 forming the back surface of the toilet seat portion 3 formed of synthetic resin is joined to the body 15 and welded by ultrasonic welding or heat welding, The leg rubber 17 is configured to be bonded to the back plate 16.

Next, the operation of the structure of this embodiment will be described. A signal from the control section 4 in the body 15 is transmitted to the toilet seat section 3 through the electric wire 11 passing through the rotating shaft 6.

As described above, according to the heating toilet seat of the embodiment of the present invention, since the rotating shaft 6 through which the electric wire 11 is inserted is filled with the synthetic resin, urine, sewage and detergent enter the toilet seat 3. Therefore, there is no possibility that the heater shaft 8 in the toilet seat 3, the overheat protector 10, the electric wire 11 and the temperature detection sensor 13 may be attached to cause a malfunction such as corrosion, and the rotating shaft 6 itself. The strength of is improved and there is no fear of breaking.

The electric wire 11 extending to the outside of the rotating shaft 6 has a sufficient length so that it is sufficiently durable even when the toilet seat 3 is rotated.

Alternatively, a method may be used in which the outer circumference of the rotary shaft 6 is a metal pipe, and a synthetic resin is inserted through a cord through the pipe.

[0018]

As described above, according to the heated toilet seat of the present invention, the following effects can be obtained.

(1) By preliminarily filling the synthetic resin through the rotating shaft of the toilet seat portion with electric wires, it is possible to prevent urine, sewage and detergent from entering the toilet seat portion, and to cause malfunction due to corrosion in the toilet seat portion. Disappear.

(2) By filling the rotary shaft of the toilet seat with synthetic resin, the strength of the rotary shaft is improved and there is no fear of breaking.
