DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a toilet seat unit used in a toilet.

[0002]

2. Description of the Related Art FIG. 4 is a sectional view of a conventional heating toilet seat.
The overall configuration of the heating toilet seat had a structure as shown in FIG.

That is, a toilet seat 2 having a heater 5 therein.
And a main body 1 containing a control device 4 for controlling the temperature of the toilet lid 3 and the heater 5. The toilet seat 2 and the toilet lid 3 are rotatably attached to the main body 1. The toilet seat 2 includes a toilet seat body 2a, a heater 5, and a toilet seat bottom plate 2b, and the heater 5 welded to the aluminum foil 6 is made of a double-sided adhesive material.
Is pasted on.

Further, the toilet seat body 2a and the toilet seat bottom plate 2b are hermetically sealed in a hollow shape by means of welding such as ultrasonic welding or vibration welding, or by means of an adhesive or a screw.

[0005] The signal line of the heater 5 is electrically connected to the control device 4, and the control device 4 calculates the detected temperature of the temperature detecting section in the toilet seat and controls the output to the heater 5. A temperature fuse is connected to the heater 5 in series. If the temperature of the heater 5 rises abnormally, the temperature fuse is blown by the heat of the heater 5 and the power supply to the heater 5 is stopped.

[0006]

The welding by ultrasonic waves or vibration, which has been performed on a conventional toilet seat, may adversely affect the built-in electronic components and the like. In addition, in the case of bonding with an adhesive, it took a long time to fix, and there was an adverse effect on the appearance due to the protrusion of the adhesive. In addition, since a solvent or the like is used, there is a possibility that the health of the worker is adversely affected. Further, in the case of welding by ultrasonic waves, vibrations, or adhesives, it is difficult to disassemble once welded.

[0007] Further, in the case of fixing by a method other than bonding, for example, by screwing, a packing or a sealing material is required at the joint in order to prevent water from entering. When packing is used, the packing must be punched in accordance with the shape of the toilet seat, and waste of material occurs. In addition, the packing must be manually inserted into the groove, and the efficiency of the assembling operation becomes very poor.

When a liquid sealing material is used, it is necessary to apply the sealing material over the entire circumference of the toilet seat, so that a large amount of material is required. Also, in the case of a heating toilet seat in which a heater is housed in the space between the toilet seat body and the toilet seat bottom plate, the tightness between the toilet seat body and the toilet seat bottom plate is increased, and the heat conductivity is improved, so that wasteful heat conduction to the toilet seat bottom plate is large. And wasteful power is consumed.

[0009]

According to the present invention, a liquid caulking agent is mounted as a sealant in a concave groove provided in a toilet seat body or a toilet seat bottom plate, and a liquid seat is fitted and assembled. The caulking agent is a toilet seat unit made of a foam molded article. According to the above invention, since the density of the liquid caulking agent can be lowered, a liquid caulking agent having a light weight and elasticity can be obtained.

[0010] Further, by foaming the liquid caulking agent, the same watertightness as the conventional one can be obtained with a small amount of use. By setting the expansion ratio to 5 times or less, preferably 2 to 3.5 times, a suitable elasticity is obtained and open cells are reduced, so that good watertightness is obtained.

In the case of a heating toilet seat in which a heater is housed in a space formed by a toilet seat body and a toilet seat bottom plate, a heat insulating effect can be obtained by having an air layer inside an elastic packing or a liquid caulking agent. There is little wasted heat conduction to the bottom plate, and energy saving is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on embodiments shown in the accompanying drawings. FIG. 1 shows a toilet seat unit according to an embodiment of the present invention.

The toilet seat unit includes a pair of a toilet seat body 2a and a toilet seat bottom plate 2b, each of which is formed of a thermoplastic resin (for example, polypropylene). A concave groove 8 is provided in the inner peripheral portion and the outer peripheral portion of the toilet seat body 2a, and a convex portion 9 forming a fitting portion is provided in the toilet seat bottom plate 2b in opposition to the concave groove 8. In FIG. 1, a concave groove 8 is provided in the toilet seat body 2a and a convex portion 9 is provided in the toilet seat bottom plate 2b. However, even if a convex portion is provided in the toilet seat body 2a and a concave groove is provided in the toilet seat bottom plate 2b, there is no problem. Absent.

Inside the toilet seat body 2a, a heater 5 welded to an aluminum foil 6 is attached to the toilet seat body 2a with a double-sided adhesive (not shown). By energizing the heater 5 when using the toilet seat, the user can comfortably use the toilet seat.

The liquid caulking agent 7 is automatically discharged and mounted along the concave groove 8 of the toilet seat body 2a by a robot equipped with a discharge gun. When the liquid caulking agent 7 is discharged and mounted, if nitrogen gas or air is mixed in the middle of the flow path, the liquid caulking agent 7 is discharged as a foam.
The expansion ratio can be easily controlled by changing the ratio of the gas to be mixed. In this example, since urethane was used as the liquid caulking material, the expansion ratio of the foam was set to 3.0 times because of the viscosity of the urethane stock solution.

After the liquid caulking agent 7 is mounted, the toilet seat body 2a and the toilet seat bottom plate 2b are fitted with the concave grooves 8 and the convex portions 9 and fixed by screws or the like, so that a toilet seat unit having excellent watertightness can be obtained. Be completed. Thereby, it is possible to prevent water or detergent from entering from the outside. When the bubbles inside the liquid caulking agent 7 are independent, it is possible to prevent water from entering from outside due to capillary action.

When the heater 5 is energized to make the use of the toilet seat comfortable in winter, since the foamed liquid caulking agent 7 has an insulating effect, wasteful heat conduction from the toilet seat main body 2a to the toilet seat bottom plate 2b. And the power consumption of the heater 5 is reduced.

Although the present embodiment has been described in terms of a configuration having only the heating toilet seat function, the same effect can be obtained with a device having functions other than the heating toilet seat, such as a hot water washing toilet seat device for performing local washing with hot water. However, the present invention is not limited to this.
