The technique using antibacterial treatment is not a fundamental solution, since it only restricts the growth of bacteria. In the technique of incorporating a germicidal lamp in the doorknob body, it is impossible to irradiate the entire portion of the doorknob that comes into contact with the hand, including the back side of the doorknob, and only a portion of the germicidal effect is possible. Regarding installation, there was also the problem of having work to install. Also, there is a limitation in its shape,
There is a problem that the places to be used are limited in each shape. The present invention has been made to solve the above problems.

[0004]

[Means for Solving the Problems] The doorknob of an arbitrary door is mounted so as to surround the doorknob, and an opening for operation is provided on the front surface of the cover body. It kills bacteria. Inside the cover, a reflector has already been obtained so that the entire door knob is illuminated with this illumination light. Further, an irradiation control means for controlling the irradiation operation of the sterilization lamp is provided, and control according to the situation is possible. The present invention has the above configuration.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The present invention is a sterilizer for a door knob, which is attached around a door knob of a door and sterilizes bacteria on the surface of the door knob by irradiation with a sterilizing lamp. The basic configuration of the sterilizer will be described with reference to FIG. A board opening (3) is provided in the center of the board (1) having an adhesive means such as a double-sided tape or an adhesive on the back surface. The base opening (3) is sized and shaped to allow any doorknob to pass through. The sterilizing lamp (2) is detachably attached to the sterilizing lamp mounting portion (8) above the substrate opening (3) on the substrate. As a germicidal lamp,
Although various germicidal lamps that have been conventionally used can be used, it is preferable to use one that does not cause harm even when the skin is irradiated. The sterilizing lamp mounting portion (8) has a structure for causing the sterilizing lamp (2) to emit light by the electric power from the power source. Above the germicidal lamp (2),
A reflector (4) is provided. This reflects the irradiation light to the upper side of the germicidal lamp (2) downward. It should be noted that although this upper reflector is described as having reflectivity in this example, it does not matter if it does not have reflectivity. A lower reflector (4) is also provided on the substrate below the base opening (3). This receives the irradiation light from the germicidal lamp (2) side and reflects it upward. In the figure, the shape is along the front side to the top. However, the lower reflection plate is not limited to this shape, and may have any shape as long as it receives the irradiation light and reflects the irradiation light evenly on the lower surface side of the door knob protruding from the base opening. A battery box (7) and a control box (15) are provided above the germicidal lamp (2). The battery box uses a battery as a power source and corresponds to a shape that can be used according to the shape of the battery. Also, the control box (15)
Includes a circuit for controlling irradiation of the germicidal lamp (2). In the figure, a switch (12) and an LED that lights up during operation are provided on the surface. Various controls can be performed by pressing this switch (12). In the figure, the wiring from the battery box (7) is not shown, but it is provided in the board (1) and in each component or partition so that power is supplied to each. . A cover (5) is detachably attached to the base (1) so as to cover these various components. The switch of this cover (12)
An operation window (6) is provided at a position where the LED (11) is exposed. A cover opening (10) is also provided for operating the door knob. The cover opening (10) has a size and shape so that a hand or an arm does not touch it in a range where the door knob is manually operated. In addition, Figure 4
As shown in (3), the irradiation from the germicidal lamp (2) is also shielded so as not to hit the user's eyes. The present invention has the above configuration. When using it, fix the doorknob to the door through the base opening in the base. Then attach the cover to the base. When the sterilizing lamp emits light in the attached state, the light illuminates the upper surface of the door knob, and the bacteria at the position disappear. Irradiation light that reaches the lower reflector from the germicidal lamp is reflected by this reflector and is irradiated to the lower surface of the door knob, and the bacteria on the surface where the irradiation light from the germicidal lamp does not reach disappear. Various control mechanisms for controlling these irradiation timings can be considered. For household use, it is used less frequently than in public places, so
Irradiation is carried out automatically every 2 to 4 hours for an arbitrary period of time showing a bactericidal effect. In addition, when the frequency of use is high such as morning and night, it is possible to separately irradiate by pressing the switch. In a public place, it is desirable to shorten the irradiation setting time and sterilize frequently. As a control method other than the above, there may be considered a method in which a sensor for detecting the hand inserted into the opening is provided, and when the hand is removed, the sensor is irradiated to immediately sterilize. Also,
In the use of the sensor, it is possible to add a function of interrupting irradiation when a hand is inserted.

As a form of the cover, as shown in FIGS. 5 to 6, it is also possible to separately provide an upper cover (16) and a lower cover (17). At this time, it is important that the shape and the mounting position be such that the reflected light from the germicidal lamp and the reflector does not reach the eyes of the user. In the case of FIG. 6, it corresponds to a rod-shaped door knob. As described above, by changing the shape of the base opening portion (3) according to the shape of the door knob, it is possible to deal with various door knobs.

Another embodiment of the present invention will be described. 7 to 8, a shield plate (9) is provided on the lower side of the cover opening (10) in order to shield the reflected light from the lower reflector (4) to the eyes more efficiently. this is,
By bending the lower side of the cover opening inward, it is possible to further prevent the diffusion of the irradiation light. Further, in order to narrow down the irradiation angle of the irradiation light, the sterilizing lamp and the reflected light are enclosed in a box to limit the winner angle, which is the invention of FIGS. 9 to 10. This is provided with a bottom surface on the upper cover, and an irradiation port (18) for irradiating the door knob is provided on this bottom surface.
Further, the cover (17) has a box-like shape with an upper surface surrounding the lower reflection plate (4). The upper surface is provided with an irradiation port (18) for allowing the irradiation light from the germicidal lamp (2) to enter the inside and reflecting the reflected light to the door knob. At this time, the irradiation angle is narrowed so that the sterilizing light is applied to the entire surface of the door knob and the sterilizing light does not reach the eyes of the user. In the above, in each of the embodiments, a rod-shaped sterilization lamp has been illustrated and described, but a curved sterilization lamp may be used as long as it has a shielding function for irradiating the front surface of the door knob and for preventing sterilization light from reaching the eyes. It does not matter even if it used.

Other embodiments will be described below with reference to FIG.
It will be described with reference to FIGS. In the present embodiment, a ring-shaped germicidal lamp (2) is used. A sterilizing lamp housing portion (20) having a function of holding this in a hollow portion and irradiating a sterilizing lamp is fixedly provided around the base opening (3) of the base (1). A reflection function is provided in the sterilization lamp storage portion (20) so that the sterilization lamp storage portion (20) can be reflected on the inner wall one after another. Further, there is provided an upper cover in which the power source, each control unit, the switch, and the like are integrated together. Further, an irradiation port (18) for irradiating the irradiation light of the germicidal lamp in the direction of the door knob is provided inside the germicidal lamp accommodating portion (20) in a slit type. The irradiation light that has passed through this slit is applied to the entire surface of the door knob. Further, the irradiation in the front direction is adjusted by this irradiation opening (18) so that it does not reach the eyes of the user. The control method is the same as that in each of the above embodiments.

Next, an embodiment using the solar cell system will be described. As shown in FIG. 13, the door (19) is provided with a solar panel (21).
This collects light from an indoor lamp in the room.
The solar panel is wired inside the door, and power is supplied to the germicidal lamp (2) through a battery, an inverter and a control unit built in the base or the door. As for the solar panel (21), it is possible to wire the solar panel (21) provided from the outside in order to further enhance the light collecting power. In this case, it can be considered that the battery, the inverter, and the control unit are external systems. This power supply system is incorporated into a configuration other than the power supply means of each of the above-described embodiments for implementation.

Next, an embodiment using an AC outlet power supply will be described. As shown in FIG. 14, wire the cord with the plug (23) to the door. This code is wired inside the door to supply power to the germicidal lamp (2) via the controller. The control unit at this time may be a known one that supplies AC power.
When using it, plug the plug (23) into the outlet (22) to operate the system using AC power.

Next, an embodiment for the door knob (13) fixedly attached to the door (19) will be described.

It is designed to be attached to the upper part of 3). The cover (5) is configured such that two members are opened left and right by an opening / closing part (26) by a hinge. As a fixing means at the time of attachment, as shown in the figure, a fixing tool (24) is arranged so as to straddle the left and right members, and is fixed with a screw (25) in accordance with a screw hole provided in the cover. The power supply and operating part are attached to the door (19). Power cord (2
In 7), power is supplied to the germicidal lamp (2) mounted in the cover (5). In the figure, the cord (27) is fixed by a belt (28) so that the cord (27) does not hang. As shown in FIG. 16, the cover (5) is provided with an arc-shaped germicidal lamp (2) so as to surround the door knob (13). At this time, since the cover (5) is divided into right and left, it is preferable that the covers (5) are provided on the left and right covers (5), respectively, and have a substantially ring shape in a closed state so as to surround the door knob (13). The lower part of the cover (5) surrounds the germicidal lamp (2) so that the irradiation light of the germicidal lamp (2) does not reach the eyes of the user. It is also possible to provide a reflection plate inside the cover (5), whereby the irradiation light of the germicidal lamp can be more efficiently applied to the door knob. The control means and the power supply means may be those used in the above-mentioned respective embodiments.

Although the respective embodiments have been described above, the use of a photocatalyst or a charge transfer catalyst can be cited as an application example that can be commonly used for these embodiments. This is to provide a catalyst layer made of a photocatalyst, a charge transfer catalyst or the like on the surface of the door knob that receives the irradiation light. The charge transfer catalyst mentioned here refers to the technology and the like described in JP-A-2002-001121.
