Description

  The present invention relates to a toilet seat unit such as a heated toilet seat or a washing toilet seat used in a toilet.

Technical background

Compared with conventional medium pressure and high pressure mercury lamps, UV-C output efficiency is remarkably high at low pressure, and the lamp life is 8000 hours, long life due to far-ultraviolet rays that provides sufficient bactericidal power when irradiated for about 10 seconds. A germicidal lamp was commercialized.
"Nippon Philips Co., Ltd. UV Low Pressure Mercury Lamp Catalog"

  In the toilet seat unit, I want to clean the toilet seat that is in direct contact with human skin and that is susceptible to germs. A sterilizer that anyone can use easily and repeatedly in a short time.

  First of all, UV-C lamps with a wavelength of 253.7, which has a particularly high bactericidal ability, are manufactured according to the shape of the toilet seat from the 180 to 280 nm deep ultraviolet region in the background of “0002”. It was found that a “toilet seat-type far-ultraviolet germicidal lamp unit” combined with the sterilizing effect of the above was devised and sufficient sterilizing power could be obtained by directly irradiating the toilet seat.

  Secondly, from the closest distance of about 10 cm from the toilet seat surface, a “sterile seat type far ultraviolet ray” of a sterilizing apparatus that irradiates the far ultraviolet light wave as close as possible on average for as long as possible for a certain time of about 15 seconds. The idea was to devise the place where the “sterilizing lamp unit” was installed, but this was solved by calling for “utilization of the back side” of the toilet lid located just above the toilet seat.

  By combining "0004" and "0005", the ability of deep ultraviolet germicidal lamps can be brought out on the toilet seat, and E. coli, S. aureus, Salmonella, etc. including O-157 can be killed in a very short time. Can do.

  Smooth wiping with a disinfectant solution on a conventional napkin, no need for disposable sheets, and the fact that the toilet seat itself is made antibacterial. As long as it has a function to operate, it can be applied to a conventional toilet seat unit and is highly versatile.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is an overall perspective view of a “toilet seat type deep ultraviolet germicidal lamp unit” in a state in which the toilet lid of the toilet seat unit is opened. On the back side of the toilet lid, a “toilet seat-type far ultraviolet germicidal lamp unit” covered with a germicidal lamp cover 3 that can be said to be the heart of the present invention is mounted. If it is excellent, does not impede the transmittance of deep ultraviolet light, and does not give a sense of incongruity when it is attached, it will stick to the cover with numerous punch holes in a thin metal plate as shown in the figure. It is not a thing. This cover is manufactured with the L-shaped thin collars shown in 4 and 6, but one of its purposes is to increase the strength of the cover, and the other is to cover the entire unit as a toilet lid. This will fulfill the two roles of providing a small bulge in the place where the screw hole fixedly mounted on the back side is opened. A total of 7 screw holes 5 and 7 are installed, and are screwed and attached to 7 nuts embedded in the back of the toilet lid at the time of molding. The shape of the cover is designed and shaped to be close to the shape of the toilet seat, so that when the toilet lid closes, it will inevitably stand by from a position directly above where the deep UV germicidal lamp can be irradiated. When the lid is closed, the sterilization lamp is turned on when it reaches an area where the sterilization light can be irradiated accurately and accurately on the toilet seat. When the sterilization is finished, a device is automatically turned off. As a result, it was possible to save unnecessary power waste. The impact absorbing pad 9 is used in the conventional toilet seat unit. The toilet seat-type germicidal lamp unit as a sterilizer is securely attached to the back of the toilet lid with a total of seven screws as described above, so that the germicidal lamp unit can be easily detached and inconvenient for maintenance. Can be omitted.

  Reference numerals 11 and 12 in FIG. 2 are a sterilizing indicator lamp and a sterilized indicator lamp attached to the toilet lid surface. This is color-coded, for example, by displaying red during sterilization, blue when sterilized, etc., so that the user can easily check whether it can be used. Further, regarding the disposition of the germicidal lamps, 13 is an external germicidal lamp, 14 is a state in which the inner germicidal lamp is mounted, and the internal state is seen through from the surface side of the toilet lid.

  FIG. 3 is a cross-sectional view for explaining a deep ultraviolet germicidal lamp unit forming the core for realizing the “sterilizing toilet seat” which is the object of the present invention. It is also a unique form that specifically realizes how the performance of deep ultraviolet germicidal lamps can be demonstrated on the toilet seat, and how it is possible to safely use lamps using mercury. This "toilet seat type far ultraviolet germicidal lamp unit" holds 3 germicidal lamp covers, 15 reflectors with unique shapes, 13 and 14 two germicidal lamps having the highest sterilizing effect, and 16 germicidal lamps. The lamp holder is integrated with four lamps, and is fixed to seven screw retaining nuts embedded in the toilet lid with seven screw screws. This unit has its own form, but the description has already been described in “0009”. In addition, the height of the mounting positions of the outer lamp 13 and the inner lamp 14 is shifted, and the reflector 15 having the shape shown in the figure is further mounted to devise a more sterilizing effect. The most effective bactericidal effect can be obtained. The power supply for the germicidal lamp is also required to be attached / detached with the unit. However, since the power plugs 17 and 18 inserted into the germicidal lamp are located inside the reflector plate, the power supply can be easily detached and attached at the same time when the unit is replaced. In order to solve this problem, the two power supply lines drawn out from the reflector plate were provided with two connectors, and if they were inserted and removed, the unit and the power supply were easily detachable at the same time. As a result, anyone can easily and easily maintain the unit with a single screwdriver. This unit is specially manufactured so that the most effective sterilization effect can be fully demonstrated when it is attached and fixed to the back of the toilet lid. This is the “toilet seat-type far-ultraviolet germicidal lamp unit” that is the object of the present invention. It is.

  FIG. 4 is an explanatory view of the installation form of the dual-type lamp and why the double-type is used. First of all, the explanation of the need for the dual system is that the plug receiving portion of the insertion portion of the germicidal lamp 17 does not emit light with respect to the light irradiation of the germicidal lamp, and further, the radiation light is hindered at the lamp holder mounting portion. In order to solve this problem, the lamps are purposely doubled, the height positions of the inner and outer lamps are shifted, and the positions of the power introduction portions of the outer and inner lamps are shifted to the left and right as shown in the figure. The position of the outer lamp holder is also shifted as shown in the figure so that the desired bactericidal effect can be obtained. However, since the power supply of each lamp was removed, the power supply of each lamp was removed by attaching / detaching the power source by inserting / removing 17a and 17b, without removing the plug to the germicidal lamp. The problem was solved by allowing the power supply to be inserted / removed at 18a and 18b, and the entire unit to be easily detached.

  In the toilet seat unit, I want to clean the toilet seat that is in direct contact with human skin and that is susceptible to germs. A sterilizer that anyone can use easily and repeatedly in a short time.

  First, a UV-C lamp having a wavelength of 253.7, which has a particularly high bactericidal ability, is manufactured according to the shape of the toilet seat from the ultraviolet range of 180 to 400 nm, which is the technical background of “0002”. We have devised a “toilet seat type deep ultraviolet germicidal lamp unit” that combines the functions of each individual, and it has been found that sufficient sterilizing power can be obtained by directly irradiating the toilet seat.

  Secondly, the “toilet seat type far ultraviolet ray” of a sterilizing apparatus that irradiates the ultraviolet light wave from the closest distance of about 10 cm from the toilet seat surface for a certain period of time of about 15 seconds as much as possible, and from the immediate vicinity where the sterilizing effect is easily exhibited. The idea was to devise the place where the “sterilizing lamp unit” was installed, but this was solved by asking for the “use of the back side” of the toilet lid located just above the toilet seat when the toilet lid closed.

  By combining "0004" and "0005", the ability of deep ultraviolet germicidal lamps can be brought out on the toilet seat, and E. coli, S. aureus, Salmonella, etc. including O-157 can be killed in a very short time. Can do.

  Smooth wiping with a disinfectant solution on a conventional napkin, no need for disposable sheets, and the fact that the toilet seat itself is made antibacterial. As long as it has a function to operate, it can be applied to a conventional toilet seat unit and is highly versatile.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is an overall perspective view of a toilet seat-type far ultraviolet germicidal lamp unit mounted with the toilet lid of the toilet seat unit opened. “Toilet seat type far-outer line germicidal lamp unit” covered with 3 germicidal lamp cover which can be said to be the heart of the present invention is mounted on the back side of 2 toilet lid, but the material of this cover is excellent in strength. If it is suitable for the cover, which does not impede the transmittance of deep ultraviolet rays, or does not give a sense of incongruity when it is installed, it is particularly sticking to the cover shown in the figure with numerous punch holes in it. is not. This cover is made with the thin L-shaped flanges shown in 4 and 6, but one of its purposes is to increase the strength of the cover and toilet lid, and the other is the whole unit. When opening a screw hole for fixing and attaching to the back of the toilet lid, it is necessary to provide a small bulge portion. A total of 7 screw holes 5 and 7 are installed, and are screwed and attached to 7 nuts embedded in the back of the toilet lid at the time of molding. The shape of the cover is designed and shaped to be close to the shape of the toilet seat, so that when the toilet lid closes, it will inevitably stand by from a position directly above where the deep UV germicidal lamp can be irradiated. When the lid is closed, the sterilization lamp is turned on when it reaches an area where the sterilization light can be irradiated accurately and accurately on the toilet seat. When the sterilization is finished, a device is automatically turned off. As a result, it was possible to save unnecessary power waste. The impact absorbing pad 9 is used in a conventional toilet seat unit. The toilet seat type germicidal lamp unit as a sterilizing device is attached and detached on the back side of the toilet lid with a total of seven screws as described above, so that the germicidal lamp unit can be easily attached and detached, and inconvenience in maintenance is eliminated. It became possible.

  Reference numerals 11 and 12 in FIG. 2 are a sterilizing indicator lamp and a sterilized indicator lamp attached to the toilet lid surface. This is color-coded, for example, by displaying red during sterilization, blue when sterilized, etc., so that the user can easily check whether it can be used. Further, regarding the disposition of the germicidal lamps, 13 is an external germicidal lamp, 14 is a state in which the inner germicidal lamp is mounted, and the internal state is seen through from the surface side of the toilet lid.

  FIG. 3 is a cross-sectional view for explaining a deep ultraviolet germicidal lamp unit forming the core for realizing the “sterilizing toilet seat” which is the object of the present invention. It is also a unique form that specifically realizes how the performance of this germicidal lamp can be demonstrated on the toilet seat and how to safely use a lamp using mercury. This "toilet seat type far ultraviolet germicidal lamp unit" holds 3 germicidal lamp covers, 15 reflectors with unique shapes, 13 and 14 two germicidal lamps having the highest sterilizing effect, and 16 germicidal lamps. The lamp holder is integrated with four lamps, and is fixed to seven screw retaining nuts embedded in the toilet lid with seven screw screws. This unit has its own form, but the description has already been described in “0009”. Further, by shifting the height of the mounting position of the outer germicidal lamp 13 and the inner germicidal lamp 14, and by mounting the reflector 15 having the shape shown in the figure, it has been devised so that a further sterilizing effect can be exhibited. The combination made it possible to obtain the most effective bactericidal effect. In addition, the power source of the germicidal lamp is required to be attached and detached together with the unit. However, since the power plugs 17 and 18 inserted into the germicidal lamp are located inside the reflector, the power source can be easily detached and attached at the same time when the unit is replaced. In order to solve this problem, the two power supply lines drawn out from the reflector plate were provided with two connectors, and if they were inserted and removed, the unit and the power supply were easily detachable at the same time. As a result, anyone can easily and easily maintain the unit with a single screwdriver. This unit is specially manufactured so that the most effective sterilization effect can be fully demonstrated when it is attached and fixed to the back of the toilet lid. This is the “toilet seat-type far-ultraviolet germicidal lamp unit” that is the object of the present invention. It is.

  FIG. 4 shows the relationship between the dual-type lamp, the lamp holder, the power connector and the like. The connector is as described in “0011” as a device for detaching the germicidal lamp unit. One sterilizing lamp has sufficient sterilizing power if it is direct light, but it is a double type for the following reason. First, the 16 lamp holders and the power plug part are portions that do not emit light or are prevented from irradiating. Therefore, the problem is solved by dipolarizing the light source and shifting the positions as shown in the figure. be able to. Secondly, when a transparent material is used for the lamp cover of the germicidal lamp unit, the transmittance may be reduced due to the material. To compensate for this, a punch hole may be made in the metal plate, Combined with the double pole of the light source, the difference in height between the inner and outer lamps, and the synergistic effect of the reflector, compared to the blind spot that occurs when using a mesh or the like, various incident angles, reflection angles, By diversifying the irradiation conditions such as causing irregular reflection, it is possible to reduce the bactericidal effect and complement the blind spot. It is a figure which shows those relations.
