Preferred embodiments of the present invention will be described below in order to further clarify the structure and operation of the present invention described above.

FIG. 1 is a perspective view showing a Western-style toilet 20 equipped with a heated toilet seat according to an embodiment of the present invention. As shown in FIG. 1, the western-style toilet 20 includes a toilet body 22 and a toilet body 2.
2, a heating toilet seat 40 and a toilet lid 26 pivotally supported at one end, a sanitary washing device 30 equipped with a washing nozzle, and a washing water tank 28.

The heated toilet seat 40 includes a horseshoe-shaped toilet seat body 50 shown in FIG. 2 and a support base 60 shown in FIG. 3 insert-molded in the toilet seat body 50. 2 is a plan view of the toilet seat body 50, FIG. 3 is a plan view of the support base 60,
FIG. 4 is a sectional view taken along the line BB of FIG. On the upper surface 62 of the supporting base material 60 shown in FIG. 3, a heater mounting groove 64 is formed in a shape along the broken line. Further, an adhered surface 66 is formed on the upper surface 62 between the heater mounting grooves 64 and the peripheral portion thereof.

The toilet seat body 50 is made of AB having a melting point of 200.degree.
It is made of S resin or PP resin having a melting point of 180 ° C., and the supporting base material 60 is also made of the same resin. Therefore, the resin melted to form the toilet seat body 50 is supported by the support base material 6.
The surface of the supporting base material 60 is melted by coming into contact with 0, and is melted with the injected resin to be firmly fixed. Although the molten resin comes into contact with the supporting base material 60 and the surface of the supporting base material 60 melts, the temperature of the molten resin decreases due to the contact, so that the inside of the supporting base material 60 also melts. There is no. Also,
By using the ABS resin or the PP resin, it is possible to manufacture it with good appearance and at low cost.

Further, as shown in FIG. 5, the heater unit 7 is provided between the upper surface 62 of the supporting base material 60 and the toilet seat body 50.
0 is provided. The heater unit 70 includes a heater 72 inserted in the heater mounting groove 64, a heat transfer sheet 74 made of aluminum foil, and an adhesive sheet 76 made of a double-sided tape or the like bonded to the heat transfer sheet 74. The heat transfer sheet 74 and the adhesive sheet 76 cover the substantially entire surface of the upper surface 62 to hold the heater 72 in the heater mounting groove 64 and have a substantially smooth surface.

Next, a method of manufacturing the heated toilet seat 40 will be described. First, the supporting base material 60 shown in FIG. 3 is manufactured by injection molding. In addition, as shown in FIG.
Adhere one first adhesive surface 77 of the adhesive sheet 76 on the
Further, the heater 72 is bonded to the other second bonding surface 78.
This work is performed using the support base 100. The support base 100 has a positioning pin 10 that moves up and down by a spring force.
Many 2 are attached. The positioning pin 102 is arranged so as to follow the shape of the heater mounting groove 64 of the supporting base material 60. Next, the heater 7 is placed between the positioning pins 102.
2 is provided, and the adhesive sheet 76 adhered to the heat transfer sheet 74 is pressed against the heater 72 side. This allows
The positioning pin 102 is pushed down, and the adhesive sheet 76
The heater 72 is adhered to. By raising the heat transfer sheet 74 and the adhesive sheet 76, the heater 72 is bonded and integrated with the heat transfer sheet 74 via the adhesive sheet 76.
The upper end surface of the positioning pin 102 is coated with Teflon or the like, and can be easily peeled off from the second adhesive surface 78 of the adhesive sheet 76.

Next, as shown in FIG. 7, the heater 7 of the heater unit 70 is placed in the heater mounting groove 64 of the support base 60.
2 is inserted and the second adhesive surface 78 of the adhesive sheet 76 is adhered to the adhered surface 66 of the supporting base material 60. After that, as shown in FIG. 8, an upper mold 112 constituting a mold 110 of the injection molding machine.
The support base material 60 on which the heater unit 70 and the like are mounted is set between the lower mold 114 and the lower mold 114. At this time, the heat transfer sheet 74
A cavity 115 is formed between the upper mold 112 and the upper mold 112. Subsequently, as shown in FIG. 9, the molten resin R is filled into the cavity 115 through the gate 116. Then, after cooling and solidifying, the mold is released and the resin molded body is taken out.
As a result, the heated toilet seat 40 is completed.

In the above embodiment, the heater 72 is inserted into the heater mounting groove 64 of the support base 60 and covered with the heat transfer sheet 74 from above, so that the heat transfer sheet 74 has the unevenness of the heater 72. The surface is concealed to form a smooth surface and firmly adhered to the upper surface 62 of the supporting substrate 60 via the adhesive sheet 76. Therefore, at the time of injection molding, the molten resin R flows on the smooth surface of the heat transfer sheet 74, so that the heater 72 is not displaced or biased even at a high injection pressure. As a result, there is no partial thin-walled portion of the toilet seat body 50 due to the deviation of the heater 72, and the reduction in strength due to the thin-walled portion does not occur.

Further, since the heat transfer sheet 74 for holding the heater 72 is made of aluminum foil, the heat of the heater 72 is efficiently transferred to the toilet seat surface 52 and the heat loss is small.

Further, when the heater 72 is attached to the heat transfer sheet 74, the heater 72 is positioned between the positioning pins 102 on the support base 100, and the heat transfer sheet 74 and the adhesive sheet 76 are pressed against the heater 72. For example, the heater 72 is bonded on the heat transfer sheet 74 in the arrangement along the heater mounting groove 64. Therefore, the troublesome work such as pushing the heater 72 into the narrow groove is unnecessary, and the work of mounting the heater 72 is easy. In addition, even if the heater mounting groove 64 has a larger sectional shape than the heater 72,
Since it is pressed by the heat transfer sheet 74, it does not shift during injection molding. As a result, the heater mounting groove 64 having a large cross-sectional shape can simplify the work of inserting the heater 72.

Further, the toilet seat body 50 is realized by insert molding in order to be integrated with the supporting base material 60, and since there is no gap at the joint, cleaning is easy and the shape of the heating toilet seat 40 itself is also. The shape of the supporting base material 60 can be varied without being restricted, and the supporting base material 60 can be easily manufactured into a shape excellent in sitting comfort and design.

Next, another embodiment according to the present invention will be described. In the above-described embodiment, as the heater unit 70, the adhesive sheet 76 is provided on one surface of the heat transfer sheet 74.
Although the heater 72 is attached and the heater 72 is adhered to the adhesive sheet 76, the heater 72 may be interposed between the heat transfer sheet 74B and the adhesive sheet 76B as shown in FIG. . In this case, as shown in FIG. 11, the second adhesive surface 78B of the adhesive sheet 76B is formed in the heater mounting groove 6
Since it also adheres to the inside of No. 4, the adhesive strength is increased, and since the heater 72 is in direct contact with the heat transfer sheet 74B, the heat transfer efficiency is increased. As shown in FIG. 12, the adhered surface 66B between the heater mounting grooves 64B may be slightly lower than the upper surface 62 to facilitate the work of inserting the heater 72 into the heater mounting groove 64B.

Further, as shown in FIGS. 13 and 14, a heat insulating sheet 79 made of polyester or the like may be interposed between the heat transfer sheet 74C and the adhesive sheet 76C. As a result, the heat to the supporting base material 60 side is cut off, and the heater 7
There is an effect that the thermal efficiency to the toilet seat surface side of No. 2 is further improved. In this case, it is desirable to cut out a part of the heat insulating sheet 79 and directly adhere the adhesive sheet 76C to the heat transfer sheet 74 to strengthen the three-layer laminated structure.

FIG. 15 shows a hollow structure of the supporting base material 60E inserted into the toilet seat body 50E. In this embodiment, since the heated toilet seat 40E itself can be formed to have a light weight and a large volume even with the same material amount, it is possible to provide a high-class feeling with a sense of mass. Further, if the cushion portion 150 is provided on the bottom surface portion 69 of the support base material 60E, the cushion portion 150 can be made lower than that formed on the upper surface portion 62E. As a result, the cushion portion 150 can be easily cleaned. As shown in FIG. 16, the toilet seat body 50F
May be formed over the entire circumference including the bottom surface portion 69 of the supporting base material 60F. In this case, the designability can be further enhanced.

FIG. 17 is a sectional view showing an end portion of another heating toilet seat 40G. If the heat transfer sheet 74G is interposed between the supporting base material 60G and the toilet seat body 50G, the joint strength is likely to decrease, but in order to prevent this, the following various configurations are adopted. A window portion 75 is formed by cutting out a part of the heat transfer sheet 74G, and the toilet seat body 50G and the supporting base material 60G are integrally welded through the window portion 75. The window 75 is formed on the heat transfer sheet 74G, and the upper surface 62 of the support base 60G is aligned with the position of the window 75.
A recess 63 is formed in the. Then, when the toilet seat body 50G is injection-molded, the molten resin enters the recess 63 through the window 75 to form the protrusion 53. As a result, the toilet seat body 5
The bonding area between 0G and the supporting base material 60G increases. The through hole 67 is formed at the end of the supporting base material 60G. Then, when the toilet seat body 50G is injection-molded, the molten resin passes through the holes 6

At the time of injection molding, the cavity 115H is filled with the molten resin R, and when the molten resin R reaches the slide die 118, the slide die 118 receives the resin pressure at the initial stage of injection. Then, the slide mold 118 is slid downward. Cavity 11 with slide mold 118 removed
5H is gradually filled with the molten resin R. That is, the molten resin R applied to the portion of the joint 60h of the supporting base material 60H is received by the slide die 118 when the resin pressure is high at the initial stage of injection, and the slide die 118 is removed when the resin pressure becomes low. It is directly received by the seam 60h and is filled in the cavity 115H. Therefore, the supporting substrate 60
The molten resin R is not filled with a high injection pressure at the portion that becomes the joint 60h between H and the toilet seat body, and burrs do not occur at the joint 60h between the support base 60H and the toilet seat body.
