Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to storage furniture installed in kitchens, dining rooms, food storage rooms, etc., and storage furniture such as sink cabinets.

Conventional Structures and Problems In general, this type of furniture is easily invaded by cockroaches, so insect traps are used or gaskets are used to prevent insects from contacting the opening and the door.

Although the insect trap has some effect because it is placed in the path of cockroaches, it cannot prevent cockroaches from invading into the storage furniture. Well, page 2. Those that use packing may have slight gaps due to aging, whereas cockroaches have only 1 mm.
It cannot be said to be a complete pest control measure because insects can invade even if there are gaps.

By the way, cockroaches secrete sticky substances on the backs of their legs, so if you apply a voltage between the cockroach's seven legs,
Very sensitive to electric shocks.

In the experiment shown below, different voltages were applied between each of the cockroach's seven limbs, and the degree of electric shock felt by the cockroach was determined through experimentation.

In the experimental apparatus shown in FIG. 1, numerals 1 and 2 are extended band-shaped electrodes made of aluminum plates or the like, and are arranged in parallel on an insulating plate 3 with an insulating interval 4 in between.

A DC voltage is applied between the trench electrodes 1 and 2 by a dry battery 5.

Now, let the cockroach 6 walk on the insulating board 3,
When the cockroach 6 contacts the electrodes 1 and 2 with all seven limbs in contact, a direct current Ichikawa from the dry battery 5 is applied to the bending of the two limbs of the cockroach 6.

Here, the voltage value of the dry battery 6 was varied variously, and the degree of electric shock reaction of cockroaches at each applied m-voltage value was investigated, as shown in Table 1 below.

Table 1 From the above results, it can be seen that cockroaches begin to feel electric shock at a DC voltage of about 6 volts.

Furthermore, when the resistance value between the seven legs of a cockroach was experimentally measured, it was about 2 and Q for the black cockroach, and about 1 MΩ for the German cockroach.

From the above experiment, since cockroaches begin to react at a voltage of about 6 volts, the current value for black cockroaches is 3 μA.
It can be seen that a single-chambered cockroach begins to feel an electric shock from a minute current of about θμA.

The cockroach electric shock test described above revealed that cockroaches are sensitive to electric shocks, but the next experiment...
In the experimental apparatus shown in Fig. 1, which is arranged on a vertical plane with the electrodes 1 and 2 lines facing laterally, cockroaches are released below the electrodes 1 and 2 on the insulating plate 3, and the cockroaches are released across the insulation gap 4. ,
An experiment was conducted at each voltage to determine whether a cockroach could pass across electrodes 1 and 2 when the cockroach was walked above the electrodes 1 and 2.

The results are listed in Table 2 below. ○ Table 2 on page 5 In this way, cockroaches can be made to fall downward by giving them an appropriate electric shock. For black cockroaches, by applying a voltage of about 20 volts or more between the electrodes, it is possible to prevent the cockroaches from moving across the electrodes on the vertical plane.

After the cockroaches are given several electric shocks as described above, they will eventually stand up on the electrode's hand, try to move back in the opposite direction, and eventually stop trying to get near the electrodes.

This is because by experiencing several electric shocks, the cockroaches acquire a kind of learning effect, visually sensing that something dangerous is present and trying to defend themselves.

This can be seen from the fact that it reacts similarly to other materials made of the same material as the electrodes to which no voltage is applied. Therefore, with such a device, in addition to simply giving an electric shock to cockroaches, it is also possible to obtain the effect of repelling cockroaches by preventing them from approaching the cockroaches.

OBJECTS OF THE INVENTION The present invention takes into account the above-mentioned problems and experiments, and aims to provide storage furniture that is not infested with cockroaches.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a small gap between any part of the main body of the storage furniture, and arranges at least one pair of electrode strips substantially parallel to each other, and the electrode strips of the pair have six electrode strips. ~3
The structure of storage furniture with an insect repellent device having a means for applying a low voltage of 0 volts is shown in Figure 7.

Description of examples An example of the present invention will be explained below based on FIG. 2.

In the figure, the main body of the storage furniture has an opening 8 at the front and a door 9 for opening and closing the opening 8. A pair of electrode bands 11 and 12 are attached to the broken part 10 of the opening 8 so as to surround the opening 8, with a small gap between them.
Further, they are arranged in parallel, and a low voltage of about 10 volts is applied to these electrode strips 11 and 12 by a dry battery 13.

In the above configuration, cockroaches that try to enter the opening 8 of the storage furniture main body 7 are exposed to the paired electrode strips 11 and 12.
Touches it, receives an electric shock, and falls outward as if flying.

Therefore, cockroaches do not invade the storage furniture main body T, and the storage furniture can always be kept sanitary. Since the insect repellent device is an electric shock type, it is semi-permanent and can effectively perform its insect repellent function at all times.

In the above embodiment, the pair of electrode bands 11° 12 was provided at the 11th peak of the opening 8, but the back side of the door corresponding to the opening slope, It may be provided at the Sendai ring, etc., and there will be no difference in its function and effect.Advantages of the Invention As is clear from the description of the above embodiments, according to the present invention, cockroaches that try to invade storage furniture can be removed by electric shock. It can be reliably removed and the storage furniture can always be hygienic.Moreover, the voltage applied to the electrode band is a low voltage of 6 to 30 volts, so there is no risk of electric shock even if a worker touches it. , is of great value.
