  Temporary toilets are mainly used outdoors by an unspecified number of people and are not easily cleaned, so they are relatively more likely to be contaminated with harmful bacteria and viruses than toilets in general households and toilets in buildings. Strong odor. On the other hand, as described in Patent Document 1, by installing an ozone generator in the upper part of the box and releasing ozone into the box, a deodorizing effect can be obtained, and harmful effects floating in the air The effect of sterilization (including sterilization) of bacteria and viruses can be expected to some extent.

  However, in the method of Patent Document 1, the door knob outside the box (the handle for opening and closing the door) cannot be sterilized, and there is almost no sterilizing effect on the door knob inside the box. The same applies to the methods disclosed in Patent Documents 2 to 4. Moreover, although the doorknob is made of an antibacterial resin or an antibacterial paint is applied, it has no sterilizing effect and no deodorizing effect. When spraying a disinfectant or deodorant, a temporary effect can be obtained, but there is a problem of lack of continuity.

  In the temporary toilet, the door knob inside and outside the box is constantly touched by the hands of an unspecified number of people and is one of the most susceptible to contamination by harmful bacteria and viruses. On the other hand, if the door knob is sterilized, it is possible to prevent or minimize the adhesion of harmful bacteria and viruses to humans due to the opening and closing of the door, and the hypothetical toilet without touching anywhere other than the door Can be used, so that a temporary toilet can be used in a sanitary manner. Under such circumstances, there is a demand for effective sterilizing means for the door knob inside and outside the temporary toilet box.

  Therefore, an object of this invention is to provide the effective sterilization means of the door knob of a temporary toilet, and the effective deodorizing means in a box.

  The present invention (Claim 1) relates to a temporary toilet with a sterilizing / deodorizing function, having a hollow double-walled door panel made of a plastic blow molded body as a part of a box of the temporary toilet, and inside the hollow interior of the door panel An ozone generator, a ventilation path for guiding ozone generated by the ozone generator into and out of the toilet box, and a fan for sending ozone generated by the ozone generator through the ventilation path are installed inside and outside the toilet box. It is connected to an emission opening that opens near the installed knob, and ozone is emitted from the emission opening toward the knob. In the present invention, the knob of the door means all the handles attached to the door for opening and closing the door.

  The present invention (Claims 2 and 3) relates to a temporary toilet with a sterilizing / deodorizing function utilizing natural circulation (wind) of the outside air, wherein an ozone generator is installed in the hollow interior of the door panel, A discharge opening is opened in the vicinity of the knob installed on the outside, and an air inflow opening leading to the hollow interior is opened outside the toilet box, and ozone is released together with air flowing into the hollow interior from the air inflow opening. It is discharged from the opening toward the knob. It is desirable that a ventilation path for guiding ozone generated by the ozone generator to the inside and outside of the toilet box is formed in the hollow interior of the door panel. The ventilation path communicates with the discharge opening and the air inflow opening.

According to the present invention, ozone is released toward the doorknob so that harmful bacteria and viruses attached to the doorknob can be effectively sterilized. Can be prevented from adhering. And since a temporary toilet can also be utilized without touching anywhere other than a doorknob, the contamination and spread by harmful bacteria, such as O-157, influenza virus, etc. can be prevented or suppressed.
In addition, the ozone released toward the knob inside the toilet box diffuses into the toilet box, sterilizes harmful bacteria and viruses floating in the air in the toilet box, and brings about a deodorizing effect in the toilet box. .

In the present invention, the ozone generator, the fan, and the ventilation path are installed inside the hollow double-walled door panel. For this reason, it is not necessary to take the space for installing these devices in the space in the toilet box, and the space in the door panel, which has not been used so far, can be used as the installation space. Moreover, since it is hidden in the door panel, it is possible to prevent the device from being damaged due to mischievous mischief. Furthermore, if these devices are installed in the vicinity of the door knob (near the discharge opening), the ventilation path can be shortened, the ozone sterilization effect is high, and the cost of the device can be suppressed.
When natural circulation (wind) of outside air is used, the number of equipment used is reduced and the energy used is also reduced, so that the initial cost and running cost of sterilization and deodorization can be reduced.
