Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of a heated toilet seat.

[Prior Art and Problems] Conventionally, a heated toilet seat 1 has a base portion 2 having a seating surface 2b formed on an upper surface 2a, as shown in FIGS. 6 and 7.
and an electric heater 3 arranged on the back side of the base part 2.
A toilet seat main body 5, which is composed of a bottom plate 4 that covers the bottom surface of the base part 2, is swingably supported on a support box 6, or the toilet seat main body 5 is connected to the toilet main body 7 via a pivot (not shown). It was supported by 2 in the diagram
0 is the valve lid. By the way, the toilet seat main body 5 uses a built-in electric heater 3 to heat the seating surface 2b of the base part 2, and in order to prevent dew condensation from forming on the surface near the rim water passage 7a of the toilet main body 7 It does not have the function of heating the surface. Therefore, conventionally, in order to prevent harmful effects such as frost damage due to dew condensation generated on the surface near the rim water passage 7a,
It was necessary to provide an electric heater 8 near the rim passageway 7a of the toilet main body 7. Therefore, the conventional method has the following drawbacks.

B. In order to attach the electric heater 8 to the toilet body 7, consideration must be given to embedding the electric heater 8 in the recess 7b provided in the toilet body 7 to make it waterproof. Therefore, the structure of the toilet bowl body 7 becomes complicated and the toilet bowl body 7 becomes expensive.

○B Since the electric heater 3 of the toilet seat body 5 and the electric heater 8 of the toilet bowl body 7 are provided separately, separate controllers are required for each electric heater, which complicates electrical wiring and requires maintenance and inspection. becomes complicated.

[Purpose of the invention] In order to solve the above-mentioned drawbacks, the present invention aims to provide a heated toilet seat that can prevent dew condensation without providing an electric heater in the toilet body.

[Structure of the invention] The gist of the invention is that the toilet seat body is composed of a base part on which a seating surface is formed, an electric heater arranged on the back side of the base part, and a bottom plate that covers the bottom surface of the base part. In the heated toilet seat, a ventilation space surrounded by the base portion and the bottom plate is formed inside the toilet seat main body, a blower is provided outside the toilet seat main body, and the blower and the ventilation space are connected to each other by a ventilation passage. A nozzle connected to the ventilation space is opened at a proper position on the bottom plate.

[Description of Embodiments] The present invention will be described below based on embodiments shown in the drawings. 1 to 3 show a first embodiment of a heated toilet seat according to the present invention. Heated toilet seat 9
a support box 11 arranged on the toilet main body 10;
Pivot supports 13, 13 (first
It consists of a toilet seat main body 12 (only one side of which is shown in the figure). The toilet seat main body 12 has a seating surface 2 on the upper surface 2a.
It consists of a base part 2 formed with a shape b, an electric heater 3 arranged on the back side of the base part 2, and a bottom plate 14 that covers the bottom surface of the base part 2. A ventilation space 15 is formed. The bottom plate 14 has a plurality of nozzles 16, 16, . being done. A blower 1 is installed in the support box 11.
7 is built in, and the blower 17 is configured to blow outside air taken in from outside the support box 11 to the ducts 18, 18. In each duct 18, a bellows-shaped flexible portion 18a formed on the outflow end side is inserted into the through hole 11a of the support box 11 and the through hole 12a of the toilet seat body 12, and the air is sent from the ventilator 15. Air is supplied into the ventilation space 15. Note that the blower 17 is attached to the support box 1.
Although it is not limited to this structure and is not shown in the drawings, it is possible to attach the toilet seat main body 12 to the toilet main body via an appropriate pivot without providing the support box 11, and to install the blower 17. Of course, it is also possible to provide it with or without being built into the protective box as appropriate.

FIG. 4 shows the main parts of the second embodiment, and the difference from the first embodiment is that the toilet seat body 12
Nozzles 16, 16, . After the hot air is divided into the inner and outer sides, it flows downstream along the inner and outer surfaces 10c and 10d due to the Coanda effect.

FIG. 5 shows the main part of the third embodiment,
The difference from the first embodiment is that the suction port of the blower 17 built into the airtight support box 11 is aligned with the outside air intake port 11b opened in the support box 11, and one blower is installed at a predetermined location of the support box 11. Alternatively, by opening a plurality of discharge ports 11c and opening an intake port 12c at a predetermined location of the toilet seat main body 12, the toilet seat main body 1
The outlet 11c and the intake 12c are configured to be in communication with each other through the packing 19 when the support box 11 is laid down in a seated state, and the inside of the support box 11 is effectively used as a ventilation path, thereby reducing the The point is that it has a simple structure.

[Function] Next, the function of the heated toilet seat according to the present invention will be explained based on the first embodiment shown in FIGS. 1 to 3.
The outside air blown from the blower 17 into the ventilation space 15 of the toilet main body 12 is heated by the electric heater 3 while passing through the ventilation space 15 and is heated to a temperature raised by the nozzle 1.
6, 16... to the rim water passage 10a of the toilet main body 10
It ejects toward nearby surfaces 10b, 10c, and 10d. The ejected hot air heats the surfaces 10b, 10c, and 10d of the toilet main body 10 near the rim passageway 10a to prevent dew condensation.

[Effects of the Present Invention] As detailed above, the heated toilet seat according to the present invention has the following practical effects because it is not necessary to attach an electric heater for preventing condensation to the toilet body.

It becomes possible to use a simple and inexpensive toilet bowl body without an electric heater, and furthermore, since wiring work for the electric heater of the toilet bowl body is unnecessary, it is possible to reduce toilet construction costs.

Maintenance and inspection become easier because the number of electric heaters subject to maintenance and inspection is reduced.
