Further, by making this heat insulating layer detachable, it is easy to clean and the like, so that it can always be kept clean.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a partially cutaway sectional view of a toilet seat device according to an embodiment of the present invention. A toilet seat 2 is placed on a toilet bowl 1 and the toilet seat 2 is further covered with a toilet lid 3 from above to constitute a toilet seat device. The toilet seat 2 includes an inverted U-shaped toilet seat main body 5 and a bottom plate 6, and a heating device 4 such as a heater is disposed on the inner upper surface of the toilet seat 2 in close contact therewith. A flange 9 is formed on the toilet lid 3 to a position covering the outer surface 10 of the toilet seat 2, and there is some gap 7 between the flange 9 and the outer surface 10. A space 8 is formed between the upper surface 11 of the toilet seat 2 and the toilet lid 3,
It is connected to the gap 7. Reference numeral 12 denotes a toilet lid support,
And a function of placing the toilet lid 3 on the toilet seat 2 while keeping the space 8. A toilet seat support 13 has a function of supporting the toilet seat 2 on the toilet 1. Reference numeral 14 denotes a support shaft for rotatably supporting the toilet seat 2 and the toilet lid 3, and reference numeral 15 denotes a storage box containing a control unit for various components placed on the back of the toilet 1.

Next, the operation and operation will be described. When the toilet seat heating switch is operated, the heating device 4 is operated, and the toilet seat 2 is maintained at the set temperature (for example, 40 ° C.). The air around the toilet seat 2 is heated, and convection occurs around the toilet seat 2 so that heat is likely to be transferred upward. In this embodiment, the upper surface 11 and the outer side surface 10 of the toilet seat 2 are covered with the toilet lid 3 and the flange portion 9. , A convection (air flow) is formed in the upper space 8.
And will not escape to the outside. Thus, convective heat loss is greatly reduced. The radiant heat from the toilet seat 2 is
And is absorbed by the toilet lid 3 and thus somewhat reduced. Since the smaller the space, the smaller the convection flow rate, the gap is preferably 20 mm or less, more preferably 10 mm or less. The narrower the effect, the greater the effect. However, if the width is too small, the play of the rotating parts of the toilet seat 2 and the toilet lid 3 cannot be increased, and the manufacturing becomes difficult. From this point, the lower limit is about 3 mm. With this configuration, energy saving of 20 to 30% is achieved.

In the present embodiment, air hardly passes through this portion. As described above, the surface is provided with the elastic layer 51 having strength and compressibility. In this way, the inflow of air from the outside can be prevented, so that convection from the toilet seat can be suppressed and energy can be saved.

Even with radiant heat transfer, heat is transmitted to the toilet lid 3 and heat loss occurs. However, unlike the conventional case, the heated air does not flow out of the space 8, so that the convective heat loss is not so large.

Therefore, a heat insulating layer 23 is provided on the toilet lid 3. Even if the inside is heated by convective heat transfer and radiant heat transfer, the heat is hardly transmitted to the outside of the toilet lid 3, so that heat radiation from the toilet lid 3 is prevented. That is, the heat loss of about 5 to 10% can be reduced.
