JP 2003-153826 A

  The conventional toilet seat heater keeps the toilet seat warm even when not in use, so the heater power is on. For this reason, electricity is wasted because electricity is always used. In addition, toilet seats that turn off when not in use consume a lot of electricity because the toilet seat is heated quickly with a heater when in use, and because the room temperature is low in cold regions and in winter, the toilet seat cannot be heated quickly. In order to keep the toilet seat at a predetermined temperature, the electric heater is turned on and power saving needs to be improved.

  In view of the circumstances as described above, an object of the present invention is to provide a Western-style toilet seat that can solve the conventional problems and realize power saving.

  In order to solve the above-described problems, in the invention described in claim 1, a fluid passage 7 that is hollow and formed in a flat shape inside the toilet seat is laid over the entire circumference of the toilet seat. The gist of the invention is that the heated fluid is circulated through the fluid passage 7 so that the temperature rises uniformly and the toilet seat temperature can be warmed up.

  According to a second aspect of the present invention, in the first aspect, there is a possibility that the fluid passage 7 formed in a hollow and flat shape is deformed when a weight applied by a human body is pressurized, and there is a possibility that the circulation of the fluid may be hindered. Therefore, the gist is that a column 11 for preventing deformation is installed in the fluid passage 7 formed in a hollow shape.

  According to the invention of claim 3, the fluid passage 7 is laid around the entire circumference in claim 1 and the heating fluid is continuously circulated without any trouble. However, when the heating fluid remains in the fluid passage, the heating fluid is changed over time. Since the heating fluid and the cooled fluid are mixed when the cooling fluid is cooled in the passage and has a heating time, the fluid passage 7 is formed on the upper side of the heating fluid intake port 8 and is heated. The fluid discharge port 9 is inclined in a spiral manner, and the drain pipe 5 is also inclined toward the sealed boiling heat-retaining hot water storage tank 2 so that the heating fluid naturally flows even if the circulation pump stops. The gist is that it is formed so as not to be discharged from 7 and remain.

  The invention according to claim 4 is that when the toilet seat is warmed with the heated fluid, the toilet seat temperature gradually decreases as the usage time becomes longer, so when the user falls to a predetermined temperature while sitting on the toilet seat, The main point is that the electric heater is turned on and heated.

  It can provide a Western-style toilet seat that saves power by eliminating wasted toilet heating time when not in use and in cold regions and shortening the toilet seat heating time.
