2. Description of the Related Art Various heating toilet seats having improved energy saving effects have been proposed. For example, JP-A-11
Japanese Patent No. 309089 discloses a toilet seat device including a heating toilet seat having a heat storage material arranged on the upper surface or the lower surface of a heater unit installed in the toilet seat, and a toilet lid having a hollow portion inside. This toilet seat device stores heat in the nighttime zone, which requires a small amount of electric power and is inexpensive, and heats the toilet seat by radiating heat from a heat storage material during the daytime. Further, since the toilet lid is provided with the hollow body, the heat radiation effect from the toilet lid is small, and energy can be saved.

However, although the heat insulation effect of the toilet lid is recognized to some extent, the air layer between the toilet lid and the toilet seat also communicates with the toilet bowl side, and heat diffusion from the toilet seat surface due to convection cannot be sufficiently prevented, resulting in energy loss. Was occurring.

On the other hand, Japanese Unexamined Patent Publication No. 11-89753 discloses a toilet seat device having a toilet seat sealing portion formed in a shape that forms a closed space together with the upper surface of the toilet seat. In this toilet seat device, since the closed space is formed on the upper surface of the toilet seat when not in use, heat diffusion from the surface of the toilet seat is reduced, the heat dissipation effect when not in use is reduced, and energy can be saved.

However, in any of these toilet seat devices, little consideration is given to heat dissipation from the surface of the toilet seat, resulting in large energy loss due to forgetting to close the toilet lid.
