A concave portion that accommodates the head portion of the screw 317 is integrally formed on the lower surface portion of the coupling hole 325.

As shown in FIG. 5, in a state where the toilet seat heater 330 is attached to the upper toilet seat casing 310 and the heat insulating material 340 is inserted, the cylindrical protrusion 342 of the heat insulating material 340 is inserted into the coupling boss 316 of the upper toilet seat casing 310. The heat insulating material 340 is installed at a predetermined position. The heat insulating material 340 covers the entire surface of both sides of the toilet seat heater 330, and the rear portion of the toilet seat heater 330 is open. The toilet seat heater 330 is provided with a cord heater 332 so as to increase the amount of heat generated on both sides of the seated user's thigh, and the heat insulating material 340 insulates the main part of the toilet seat heater 330.

Since it can suppress, the heat insulation effect of the whole toilet seat can be heightened.

<3> Toilet Seat Operation and Action In the toilet seat device 100 according to the present embodiment including the toilet seat 300 having the above-described configuration, when the toilet seat device 100 is in an energized state, the toilet seat 300 maintains a state of being kept at a set temperature. . The set temperature can be changed according to the user's preference using the operation switch 212, and can be adjusted in the range of 35 ° C to 40 ° C. Energization of the toilet seat heater 330 is controlled by detection data of a thermistor (not shown) installed on the surface of the soaking plate 331 of the toilet seat heater 330 corresponding to the set temperature.

  The heat generated by the code heater 332 is transmitted to the soaking plate 331, diffused to the entire surface of the soaking plate 331 by heat conduction, and transferred from the entire surface of the soaking plate 331 to the upper toilet seat casing 310 to set the seating surface 313 at the set temperature. Keep warm.

  The heat released downward from the toilet seat heater 330 by radiation and convection is suppressed by the heat insulating material 340 from moving downward.

  In addition, the heat released to the rear cavity 306 of the toilet seat 300 where the heat insulating material 340 is not disposed is transmitted to the lower toilet seat casing 320, but the side and front portions of the heat insulating material 340 are separated by the rear end rib 345. By preventing movement to the heat insulating space 305, it is possible to suppress the release of a minimum amount of heat.

  In addition, the rear part of the toilet seat 300 has a small contact area with the human body seated, and the contact pressure is low. Therefore, the amount of heat generated per unit area of the toilet seat heater 330 is set to be small, and is discharged from the rear part of the toilet seat 300 wastefully. The heat is small with respect to the amount of heat generated by the entire toilet seat heater.

  As described above, the toilet seat device according to the present embodiment has the toilet seat heater attached to the lower surface of the upper toilet seat casing of the toilet seat, and the heat insulating material is disposed below the toilet seat, so that the heat of the toilet seat heater is transmitted to the lower side. Thus, a toilet seat device with high energy saving can be realized.

  Moreover, energy efficiency can be improved more by forming a rear-end rib in both the rear-end parts of a heat insulating material, and suppressing the movement of the air inside a toilet seat.

  Further, since the insulation coating of the cord heater of the toilet seat heater and the heat insulating material are not in direct contact with each other, the deterioration of the insulation coating of the cord heater can be suppressed, and safety and durability can be increased.

  As described above, the toilet seat device according to the present invention has high energy savings and can suppress the deterioration of the cord heater, and thus can be applied to other uses such as a heating appliance.
