The present invention has been made in consideration of the above circumstances, and provides a sanitary toilet seat device for a Western-style toilet that can always keep the surface of the toilet seat that can directly contact the skin of the seated person clean and hygienic. The purpose is.

[Structure of Invention]

The sanitary toilet seat device for a Western-style toilet according to the present invention, between the toilet seat and the toilet lid, which are respectively provided on the Western-style toilet so as to be undulating,
A sterilizable metal plate is movably arranged between a closed position in which the toilet seat is in close contact with the upper surface and an open position in which the toilet seat is separated from the toilet seat, so that the toilet seat itself can always be kept hygienic. It is characterized by having done.

[Embodiment 1] The following will describe one embodiment of the present invention with reference to FIGS. 1 to 3.

As shown in FIG. 1, a toilet seat main body 1 is attached to the western-style toilet 7 near the rear end of the upper surface so that the toilet seat main body 1 can be raised and lowered. In the vicinity of the rear end portion of the toilet seat body 1, a metal plate 3 having substantially the same shape as the toilet seat body 1 and having bactericidal properties is similarly provided so as to be capable of undulating so as to cover the toilet seat body 1 from above. Further, a toilet lid 2 is provided so as to be able to rise and fall so as to cover the metal plate 3 from above. The toilet seat body 1 is made of a commonly used synthetic resin. The metal plate 3 is made of copper or a copper alloy material, and as the copper alloy material, for example, brass, phosphor bronze, aluminum bronze, nickel copper, nickel silver, white copper and the like are suitable. Also, the metal plate 3
Is formed of a single material in this embodiment, but may have a structure in which a metal film such as a copper foil is formed on the entire outer surface of the resin plate. As shown in FIGS. 2 and 3, such a metal plate 3 has a shape that follows the shape of the upper surface of the toilet seat body 1, and the inner and outer peripheral edges of the metal plate 3 are touched by the user. It is chamfered or curled so that it will not be damaged.

The toilet lid 2 is leaned against the low tank 4 side and seated on the sterilizing metal plate 3 on the toilet seat body 1 lying on the toilet 7, or the toilet lid 2 and the metal are used. The plate 3 is leaned against the low tank 4 side, and is directly seated on the sterilizing metal plate 3 and the toilet seat body 1 which has been in a close contact with the metal plate 3 before use.

As described above, the sterilizing metal plate 3 and the toilet seat body 1 are in close contact with each other depending on the usage mode other than when the toilet 7 is used, or even when the toilet 7 is used. The sterilizing effect can be obtained not only on the plate 3 but also on the toilet seat body 1 in close contact with the metal plate 3.

That is, it was confirmed that the copper or copper alloy-based material forming the metal plate 3 has a remarkable bactericidal function as a result of the following experiment.

The sterilizer used in the experiment is Staphylococcus which causes skin diseases such as skipping and coughing. Then, each of the six glass containers with a lid contains 10 ml of the culture solution, 0.1 ml of the above-mentioned staphylococcal stock solution, and a copper or copper alloy-based metal piece as a test object, and is placed inside a thermostatic box. The change in the number of bacterial cells after keeping at 37 ° C. for 18 hours was investigated. The results are shown in Tables 2 and 3.

In addition, "control" in the table means the above glass container with a lid,
This is the case where only the culture solution and the staphylococcal stock solution are contained, and the metal piece as the test object is not included.

As is clear from Tables 1 and 2 above, in the toilet seat formed only of the conventionally used synthetic resin material (ABS resin), the toilet seat itself has no bactericidal power. On the other hand, a remarkable bactericidal effect was recognized for copper or copper alloy materials. In particular, aluminum bronze was completely aseptic, and other copper alloy materials and pure copper were almost aseptic.

[Embodiment 2] This embodiment is an example applied to a heated toilet seat, and as shown in FIG. 4, it has a hollow structure having an electric heater 5 inside a toilet seat body 1 made of synthetic resin. A metallic plate 3 having a sterilizing property is arranged between a toilet seat, a so-called heated toilet seat 6 and the toilet lid 2. The rest of the configuration and usage of this embodiment are the same as those of the first embodiment,
Corresponding members having the same function are designated by the same reference numerals and the description thereof will be omitted. This also applies to the following examples.
