[Problems to be solved by the invention] A heated toilet seat cannot heat the entire toilet room. Further, although a heat pump type air conditioner can heat the entire toilet room, there is a problem in that the upper part of the toilet room is warmed and it is difficult to warm the feet.

In order to prevent a fire, the electric heater must be turned off when the tray is not used, and it is not suitable for raising the overall temperature of the toilet room. In addition, with an electric fly, the clothes may be burnt when brought close to the toilet user, and the warmth rapidly becomes poor when the clothes are moved away. Moreover,
If the toilet room is small, it cannot be moved far away, and it is often necessary to reduce the output of the heater to use it, and it may be difficult to perform sufficient heating.

[Means for Solving the Problems] A Western-style toilet bowl of the present invention is a Western-style toilet bowl having a toilet bowl on the front side and a toilet seat pivotably attached to the toilet bowl in which a warm air passage is provided to the front side of the toilet bowl. It is extended integrally with or separately from the toilet, the front end of the warm air passage is opened at the front side of the toilet, a warm air generator for the warm air passage is attached, and the seat is seated on the toilet seat. A seating switch that is turned on during all the time is provided, the warm air generator is capable of at least two-level output control, and a timer is attached to the warm air generator. Is on, the warm air generator is operated at high output, and while the timer is on and the seating switch is off, the warm air generator is operated at low output. To do.

[Operation] In the Western-style toilet bowl of the present invention, warm air is blown out from the front portion of the toilet bowl, so that it can be warmed from the user's feet. Also,
There is no risk of burning clothes because it is heated by hot air.

In the present invention, the warm air generator operates at a low output while the timer is on, and the warm air having a relatively low temperature is blown out.

On the other hand, when the human body is seated on the toilet seat, the seating switch is turned on, the warm air generator operates at a high output, and hot air having a relatively high temperature is blown out during the sitting time. Since the mima actuation system is also adopted in this way, it is possible to raise the overall temperature in the toilet room by blowing hot air even when the tray is not used.

In this way, the hot air generator 31 is operated continuously (and at low output when there is no seated person) only during times when the tray is frequently used, so that the entire toilet room is saved while saving electricity bills. Can be heated and both comfort and economy requirements are met.

Since the electric heater 81 is a ceramic heater and the temperature is raised immediately after energization, warm air is blown out immediately after sitting.

In the above embodiment, the output of the electric heater is switched in two stages, but it may be switched in three or more stages.

The above embodiment relates to a wall-mounted western-style toilet, but in the present invention, the floor-standing type where the western-style toilet is simply placed on the floor of the toilet room, or the floor while the rear end face of the western-style toilet is in close contact with the wall surface It can be applied to various Western-style toilets such as floor-wall type installed on the surface.

All of the above embodiments are examples of the present invention, and it is obvious that the number of outlets, the installation position of the hot air passage, the blowing direction of the hot air, and the like may be other than those shown in the present invention. Further, a warm air volume switching mechanism may be provided.

[Effect] As described above, in the Western-style toilet bowl of the present invention, warm air can be blown from the toilet bowl to perform heating, and the user can be warmed from their feet. In addition, since it is a heating system using warm air, it is excellent in safety such that there is no risk of burning clothes. Furthermore, it is possible to heat the entire toilet room. Therefore, according to the present invention, it becomes possible to use the toilet very comfortable especially in winter when the temperature is low.

Further, in the present invention, it is also possible to prevent the dew condensation by warming the toilet bowl by blowing warm air in the high humidity period such as rainy season.

In the present invention, when the human body is seated, warm air having a relatively high temperature is blown out, so that the power consumption is extremely low and it is extremely economical.

In the present invention, since the warm air is blown out during the time set by the timer, the entire toilet room can be heated. Also in this case, if the human body sits down, hot air of a higher temperature will be blown out, and the feet of the toilet user can be surely warmed.
