BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary pest repellent device for repelling sanitary pests such as cockroaches appearing around electronic appliances such as refrigerators, system kitchens, cupboards and the like.

[0002]

2. Description of the Related Art Unusual hygiene pests such as cockroaches have appeared in the living spaces of ordinary households since the beginning of early summer.
In particular, kitchens, dining rooms, and living rooms frequently appear due to food and water for sanitary pests, and sanitary pests tend to nest because they prefer moderate temperature and humidity. Due to the recent change in the form of dwelling to a highly airtight dwelling, it is unlikely that it will appear during new construction, but once it has invaded and nested, it may rapidly breed and increase in number. There have also been regional changes, and it was previously said that there were no cockroaches in Hokkaido,
Recently, breeding has been confirmed mainly in well-heated urban areas.

Among them, cockroaches have pathogenic bacteria such as Salmonella in their limbs and feces, and breeding in the living space is unsanitary and gives discomfort to consumers. We have devised measures to cope with such problems as sprays, insect traps, and stationary repellents that use boric acid, but once they occur, such insecticidal methods cannot keep up with the number of breeding and the total number does not decrease. . Cockroaches also invade from the outside through the gap around the drainage pipe, nest in the back of system kitchens, furniture, etc. and breed.

Further, there is an electric pest controller of a type to be attached to a system kitchen as disclosed in Japanese Patent Application Laid-Open No. 172510/61. However, since the wiring structure is complicated, the product cost is high and the electric stimulation upon contact is generated. Since it has a repellent effect, it suppresses the entry into the cabinet, but it does not lead to a decrease in the breeding number of the entire space.

The present invention prevents the invasion of sanitary pests such as cockroaches from the outside and the nesting and breeding in the rear surface of the hygienic pest repellent body, in the lower part where it is difficult to clean. An object is to obtain a sanitary pest repellent device having.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a drug diffusion stand located at the bottom of electrical appliances such as refrigerators, system kitchens and sanitary pest repellents such as cupboards. And a space for diffusing the sanitary pest repellent agent inside the pedestal part.

According to the present invention, by spraying and diffusing the sanitary pest repellent agent on the medicine diffusion stand located below the sanitary pest repellent such as electric appliances such as refrigerators, system kitchens, and cupboards, It is possible to prevent invasion of sanitary pests such as cockroaches from the outside, prevent nesting of sanitary pests in the room, and prevent breeding.
