Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to storage furniture having a device for preventing the invasion of cockroaches, which are sanitary pests that live in kitchens, kitchens, and other residences.

Conventional Structure and Problems Since cockroaches generally have sticky substances attached to the backs of their legs, it is relatively easy to give an electric shock by applying a voltage between the two legs. Utilizing these characteristics of cockroaches, it is effective 2.

Electric insect repellent devices that can effectively repel insects have been considered. This electric shock type insect repellent device is constructed as shown in FIG. 1, in which numeral 1 denotes an insect repellent device, and it is used by being attached to a vertical surface of a wall surface 2 with an adhesive or the like. This insect repellent device 1 consists of an insulating base material 3 made of phenolic resin or the like, and band-shaped electrodes 5 and 6 made of stainless steel, aluminum, etc., arranged in parallel on the upper surface of the insulating base material 3 with a minute insulation interval 4 interposed therebetween. , 6, a voltage is applied by a dry cell battery 7.

Now, the cockroach 8 is made to walk toward the insect control device 1 from below, and when the cockroach 8 straddles one limb between the electrodes 6, 6, the voltage of the dry battery 7 is applied to the cockroach 8.

Experiments have shown that black cockroaches and German cockroaches begin to feel an electric shock when the voltage of the dry battery 7 is around 6 volts. When the voltage of the dry battery 7 is further increased in the trench, the cockroach 8 passes through the insect control device 1.
I felt a strong electric shock and jumped and fell downward.

Therefore, by using such a device, it is possible to prevent cockroaches from entering.

FIG. 2 shows an example in which such an insect repellent device 1 is installed on the protruding end surface around the opening of a storage 10 having a door 9 that can be opened and closed. The purpose is to prevent the cockroaches 8 from entering by giving an electric shock to them.

However, all of them had the following problems. In other words, in FIG. 3, the door 9 is currently in an open state, and the cockroach 8 is trying to enter the chamber from below the floor surface 11. When the cockroach 8 walks, it receives an electric shock and normally falls downwards as shown by arrow 12, unable to enter the refrigerator, but when cockroach 8 walks fast, the momentum of its walking sometimes overcomes the electric shock. As shown by arrow 13, it may reach the inside of the refrigerator and be thrown away.

1.As shown in Figure 4, when door 9 is closed, -
This is a case where the cockroach 8 tries to enter the cabinet from the opposite direction through the gap between the cabinet 1o and the door 9. Normally, the cockroach 8 receives an electric shock when the electrodes 5 and 6 are sliced with one of its limbs. , the cockroach 8 then tries to escape outside the cabinet as shown by the arrow 14, but when the cockroach 8 receives the electric shock, it inserts many parts of its body between the cabinet 10 and the door 9. As a result, they sometimes fell downward as shown by arrow 16 and entered the refrigerator.

OBJECTS OF THE INVENTION The present invention aims to solve the above-mentioned problems and to provide storage furniture equipped with an insect repellent device that more reliably exhibits its insect repellent effect.

Structure of the Invention The present invention provides an insect repellent device disposed on the protruding end surface around the opening of a containment box body to achieve the above-mentioned object, in which the width dimension of the strip electrode located on the inside toward the opening is set at an insulating interval. By making the width wider than the width of the band-shaped electrode located outside the opening, the electric shock is applied to the cockroaches as far outside the opening as possible, thereby reliably preventing cockroaches from entering the chamber.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIGS. 5 to 7, reference numeral 16 is a storage with a door that can be opened and closed, and an insect repellent device 1 is attached to the protruding end surface around the opening.
8 are arranged.

The insect repellent device 18 includes an insulating base material 19 and band-shaped electrodes 21 and 22 disposed on its upper surface with a minute insulation gap 2o between them, and a voltage of about 2o volts is applied between the electrodes 21 and 22 by a dry battery 23. is being applied.

Here, the width of the electrode 21 located on the inside toward the opening is made wider than the width of the electrode 22 located on the outside.

The effects of the above configuration will be explained below.

In FIG. 6, the door 17 is in an open state, and the cockroaches 24 are trying to enter the refrigerator from below the floor surface 25. Therefore, when the cockroach 24 straddles between the electrodes 21 and 22 with one limb, it receives an electric shock due to the voltage applied by the dry cell battery 23, but the width of the electrode 21 must be set wider than the width of the electrode 220. Therefore, the electric shock can be given to the cockroach 24 at a lower position than in the conventional example shown in FIG.

Therefore, the cockroach 24 has not yet gained sufficient walking momentum at the position where it received the electric shock, so it will not be able to overcome the electric shock and invade the refrigerator with its walking momentum as in the conventional case. It falls downward as shown by arrow 26.

Further, in FIG. 7, the door 17 is in a closed state, and the cockroaches 24 are trying to enter the storage from above through the space between the storage 16 and the door 17.

Here again, as long as the width of the electrode 210 is made wider than the width of the electrode 220, the electric shock can be applied to the cockroach 24 at a higher position than in the conventional example shown in FIG. Therefore, at this point, the body of the cockroach 24 is
The degree of intrusion into the space between the door 17 and the door 17 is small, and it is easy to escape from the electric shock to the outside of the refrigerator as shown by the arrow 27, and there is almost no intrusion into the interior of the refrigerator.

Well, the above describes the case of invasion from above, but
A similar effect can be obtained against the invasion of cockroaches from the side between the storage 16 and the door 17.

In addition, in order to give the electric shock to the cockroach as far outside the opening as possible, as shown in Figure 8, even if the width dimensions of the electrodes 28 and 29 are equal, It is possible to narrow both. However, in this case, some cockroaches have a long walking distance, and in this case, they may pass the electrode 28 by one step, and the cockroach may not be given an electric shock. Since the protruding end surface 31 of the opening of the shrunk storage 30 is not completely covered with the insect repellent device 32, the appearance is not good either.

As shown in FIG. 9, a cockroach has six limbs, of which the distance 33 between the forelimbs and the middle limbs is generally wider than the distance 34 between the hind limbs and the middle limbs. In FIG. 9, a indicates the German cockroach, b indicates the black cockroach, C indicates the Japanese cockroach, and d indicates the American cockroach.

Therefore, according to the insect repellent device of the present invention, the inner electrode 21, which has a wide width, reliably captures the forelimb with a wide step d], and the outer electrode 22, which has a narrow width, can capture the distance 34 between the middle leg and the hind leg. Also narrow, it is possible to capture either of these limbs, ensuring that one limb of the cockroach 24 is connected to the electrode 21.22.
By touching between them, you can give an electric shock to Gokip1no.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, when cockroaches enter through the opening of a storage cabinet, an electric shock is reliably applied to the cockroaches and the cockroaches are expelled from the cabinet. ,
You can obtain an electric insect repellent device with very high insect repellent effect 1.
