Description

  The present invention relates to a toilet seat sterilizer.

A Western-style toilet is used by an unspecified number of people, and since the user's skin directly touches the toilet seat, the toilet seat is likely to be violated by various germs and unsanitary.
A dirty toilet seat may be cleaned with a sanitizing napkin, but it is troublesome to perform a cleaning operation every time it is used.

  In order to eliminate such a burden in cleaning work, for example, Patent Document 1 discloses a toilet bowl that sterilizes toilet seats using ultraviolet rays.

  In the toilet bowl disclosed in Patent Document 1, a recess is provided on the bottom surface of the upper lid located on the toilet seat, and an ultraviolet lamp is provided in the recess. The recess is mirror-finished, and a covering material for protecting the ultraviolet lamp is attached to the recess.

Japanese Utility Model Publication No. 63-138200

  However, in the toilet bowl disclosed in Patent Document 1, since the ultraviolet lamp is provided at substantially the center of the upper lid, the toilet seat cannot be directly irradiated with ultraviolet rays.

  Moreover, although it is a scale, even if it is provided on the upper lid so that the ultraviolet lamp is located on the toilet seat when the upper lid is closed so as to cover the toilet seat, the bases located at both ends of the ultraviolet lamp, that is, the base When the electrical contact pin and the contact of the socket connected to the electrical contact pin are located on the toilet seat, the toilet seat region facing the base and the socket is not sterilized.

  Further, when the ultraviolet lamp is installed on the upper lid so as to extend along the toilet seat, it is necessary to support the ultraviolet lamp at several places, but the lamp is supported from below as in a conventional home fluorescent lamp. If a flexible metal clip is used, the toilet seat area facing the clip will not be sterilized.

  Accordingly, the present invention has been invented to solve the above-described problems, and an object of the present invention is to provide a toilet seat sterilizer that reduces the area of the toilet seat that is not sterilized.

  To achieve the above object, a toilet seat sterilizer according to the present invention is attached to a toilet body, a toilet seat attached to the toilet body, and the toilet body so that the toilet seat can be covered from above. A toilet bowl having a toilet seat lid and a toilet seat sterilizer for sterilizing the toilet seat, wherein the toilet seat sterilizer rotates the toilet seat lid to a toilet seat closed position where the toilet seat cover covers the toilet seat Sometimes the electrical connector attached to the toilet seat lid so as not to be positioned vertically above the toilet seat, and the toilet seat closed position of the toilet seat lid connected to the electrical connector and extending along the shape of the toilet seat A pair of circular cross-sectional sterilizing lamps for sterilizing the toilet seat, the pair of sterilizing lamps being spaced apart from each other, and in the toilet seat closed position of the toilet seat lid, A first holder that is mounted in parallel with each other in the vertical direction and for attaching the pair of sterilizing lamps to the toilet seat lid, the mounting means being disposed between the pair of sterilizing lamps And a second holder extending from the first holder and adapted to be attached to the toilet seat lid, wherein the first holder contacts a part of the outer surface of each sterilizing lamp. And a connecting portion extending between the arc-shaped support surfaces, and the distance between the arc-shaped support surfaces is such that the arc-shaped support surfaces are in contact with the outer surfaces of the sterilizing lamps. When the first holder is disposed between the pair of sterilizing lamps, the first holder is dimensioned so as to be sandwiched between the pair of sterilizing lamps 7.

  In this configuration, when the toilet seat cover is rotated to the toilet seat closed position, the sterilization lamp on the lower surface of the toilet seat cover faces the toilet seat as a whole, so that the toilet seat can be sterilized by the sterilization light from the sterilization lamp.

  In particular, when the toilet seat lid is in the toilet seat closed position, the electrical connector is not positioned vertically above the toilet seat, so the electrical connector does not prevent the disinfection lamp from being placed all around the toilet seat, Can be sterilized.

  Further, since the first holder is sandwiched between the pair of sterilizing lamps and this first holder is attached to the toilet seat lid via the second holder, the first holder emits sterilizing light emitted from the sterilizing lamp toward the toilet seat. The amount to be blocked can be reduced.

  In this invention, it is preferable to have a reflecting plate that is attached to the lower surface of the toilet seat lid and reflects sterilization light from the sterilization lamp toward the toilet seat at the toilet seat closed position of the toilet seat lid. In this configuration, the sterilizing light from the sterilizing lamp can be efficiently applied to the toilet seat.

  Moreover, it is preferable to have a sterilization lamp cover that is attached to the lower surface of the toilet seat cover and covers the sterilization lamp. In this configuration, the sterilizing lamp can be protected by the sterilizing lamp cover.

Furthermore, the sterilizing lamp emits sterilizing light when the toilet seat lid is moved to the toilet seat closed position, and stops sterilizing light emission after 10 to 13 seconds have passed since the sterilizing light was emitted. Is preferred. With this configuration, it is possible to eliminate the waste of constantly emitting germicidal light.
Furthermore, it is preferable that an indicator lamp indicating the operating state of the sterilizing lamp is provided on the toilet seat lid.

  ADVANTAGE OF THE INVENTION According to this invention, the toilet seat sterilizer which can sterilize a toilet seat without anyone's hand can be provided.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 schematically shows a Western-style toilet 30 equipped with a toilet seat sterilizer according to the present invention.

  The Western-style toilet 30 is attached to the toilet body B so as to be rotatable around the rotation axis P so that the toilet seat 2 can be covered from above the toilet body B, the toilet seat 2 attached to the toilet body B, and so on. The toilet seat lid 1 is provided. The toilet seat 2 includes a collar support surface 2A that is generally annular, and a central opening 2B is formed inward of the collar support surface 2A.

  The toilet seat sterilization apparatus has a pair of sterilization lamps 7 provided on the lower surface 1A of the toilet seat lid 1. As shown in FIG. 2, the pair of sterilizing lamps 7 are located vertically above the buttocks support surface 2 </ b> A of the toilet seat 2 when the toilet seat lid 1 is rotated to the “toilet seat closed position” where the toilet seat cover 1 covers the toilet seat 2. It is attached to the lower surface 1A of the toilet seat lid 1 so as to be positioned.

  The pair of sterilizing lamps 7 includes an inner sterilizing lamp 7A and an outer sterilizing lamp 7B disposed outside the inner sterilizing lamp 7A. Each of the sterilizing lamps 7A and 7B is constituted by a rod-shaped lamp having a circular cross section. ing.

  Both ends of each sterilizing lamp 7A, 7B are electrically connected to a male connector 14A, and this male connector 14A is electrically connected to a female connector 14B attached to the toilet seat lid 1, The electrical connector 14 is constituted by the male connector 14A and the female connector 14B. An electrical cord 14C extends from the female connector 14B, and power is supplied to the sterilizing lamps 7A and 7B from an external power source (not shown) via the electrical cord 14C.

The electrical connector 14 is positioned adjacent to the rotation axis P of the toilet seat lid 1 so that it is not positioned vertically above the buttocks support surface 2A of the toilet seat 2 when the toilet seat lid 1 is in the “toilet seat closed position”. Yes. With this arrangement structure, it is possible to prevent the electrical connector 14 from hindering the irradiation of the ultraviolet light from the sterilizing lamp 7 onto the buttocks support surface 2A of the toilet seat 2.
The electrical connector 14 is covered by a connector cover 14D from below.

  As can be seen from FIG. 3C and FIG. 6, the inner sterilizing lamp 7A and the outer sterilizing lamp 7B are spaced apart from each other over the entire length, and when the toilet seat lid 1 is in the “toilet seat closed position”, The toilet seat 2 is juxtaposed in the lateral direction above the buttocks support surface 2A.

  Both ends of the lamps 7A and 7B extend linearly from the male connector 14A to form extended end portions ES1 and ES2, and the central portions of the lamps 7A and 7B extending between the extended end portions ES1 and ES2 are It extends along the buttocks support surface 2A of the toilet seat 2 and constitutes an annular portion AS.

  The toilet seat sterilizer also has attachment means for attaching the lamps 7A, 7B, in particular the annular part AS, to the toilet seat lid 1.

  As shown in FIGS. 4, 7 and 8, the mounting means is disposed between the annular portion AS of the lamp 7A and the annular portion AS of the lamp 7B, and is sandwiched between these annular portions AS. In particular, it has an H-shaped first holder 15 and a second holder 16 attached to the first holder 15. In this embodiment, three pairs of the first holder 15 and the second holder 16 are used, and the three pairs of the first holder 15 and the second holder 16 are arranged at equal intervals in the annular portion AS of the lamp 7. .

  Each first holder 15 has a pair of arcuate support surfaces 15A that abut on part of the outer surfaces of adjacent sterilizing lamps 7A and 7B, and a connecting portion 15B extending between these arcuate support surfaces 15A. The distance 15D between the pair of arc-shaped support surfaces 15A of each first holder 15 is such that the pair of arc-shaped support surfaces 15A are adjacent to the outer surface of the adjacent sterilizing lamp. When arranged between the sterilizing lamps 7A and 7B, the first holder 15 is determined to be held by the adjacent sterilizing lamps 7A and 7B. Accordingly, the distance 15D between the arcuate support surfaces 15A of the first holder 15 is slightly larger than the distance between the sterilizing lamps 7.

  The length of the arc of each arcuate support surface 15A of the first holder 15 is sized to be about 1/3 of the (inner) half of the circumference of each sterilizing lamp 7A, 7B. Even if the arc length of each arc-shaped support surface 15A is so short, the first holder 15 is sandwiched between the sterilizing lamps 7A and 7B themselves, so that the first holder 15 does not fall off from the sterilizing lamps 7A and 7B. On the other hand, as can be seen from FIG. 7, these arc-shaped support surfaces 15A abut against the sterilizing lamps 7A and 7B from the side, and also have a small area of abutment, so that they are irradiated from the sterilizing lamps 7A and 7B. The amount of blocking the ultraviolet rays toward the buttocks support surface 2A can be reduced as compared with the case of using a flexible metal clip in a conventional home fluorescent lamp.

  The arcuate support surface 15A of the first holder 15 and the sterilizing lamp 7 may be fixed with an adhesive. In this case, it is possible to prevent the first holder 15 from moving between the sterilizing lamps 7 by opening and closing the toilet seat lid 1. Alternatively, instead of the adhesive, the movement of the first holder 15 may be prevented by providing a material having a high friction coefficient, for example, a rubber sheet on the arc-shaped support surface 15A of the first holder 15.

The toilet seat cover mounting portion 16A includes a horizontal mounting portion 16a formed by one end portion of a metal plate, and the horizontal mounting portion 16a is mounted on a reflection plate 13 to be described later using, for example, an adhesive (FIG. 4). . Instead of the adhesive, a screw that penetrates the horizontal mounting portion 16a and the reflection plate 13 and engages with the toilet seat lid 1 may be used.

  The first holder accommodating portion 16B is shaped so as to support the connecting portion 15B of the first holder 15 from below, and is elastically deformed so that the other end portion 16b of the metal plate is away from the horizontal mounting portion 16a. Fifteen connecting portions 15B are shaped to be received.

  The entire width of the second holder 16 is substantially equal to the width of the connecting portion 15B. Accordingly, the second holder 16 is irradiated from the sterilizing lamps 7A and 7B and sterilized lamps 7A and 7B sandwiching the first holder 15 and thus the first holder 15 without blocking the ultraviolet rays directed toward the buttocks support surface 2A of the toilet seat 2. Can be fixed to the lower surface 1 </ b> A of the toilet seat lid 1.

  The lower surface of the toilet seat lid 1 is also provided with a reflecting plate 13 for reflecting the sterilizing light from the sterilizing lamp 7 toward the toilet seat 2 when the toilet seat lid 1 is rotated to the “toilet seat closed position”. The reflector 13 has a generally elliptical annular shape so as to cover the entire sterilizing lamps 7A and 7B, as can be seen well in FIG. 3b, and a semicircular arc shape that opens downward as can be clearly seen from FIG. It has a cross section.
