Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage furniture, a sink cabinet, an underfloor storage, or an electric shock attached to a housing such as a bathroom or a storage, which is installed in a kitchen, a dining room, a food storage room, or the like. The present invention relates to an insect repellent device.

2. Description of the Related Art Generally, in this kind of furniture, cockroaches are easily penetrated, and insect traps are used or packing for insect repelling is provided at a contact portion between an opening and a door. Since the insect trap is arranged in the cockroach passage, although there is a slight effect, those using packing may cause a slight gap due to aging, while the cockroach has a gap of only about 1 mm. Because they can invade, they are not an effective insect repellent.

By the way, since cockroaches secrete an adhesive substance on the back of their limbs, they are very sensitive to electric shock when a voltage is applied between their two limbs.

Under such circumstances, an electric shock type insect repelling device as shown in FIG. 5 has been developed. That is, two electrode strips 32, 32 'are disposed on an insulating plate 31 with an insulating gap 33 interposed therebetween, and a low voltage, for example, a voltage of 6 to 20 volts is applied to the electrode strips 32, 32' by a power supply 34. It is supposed to.

Now, it has been confirmed that when the cockroach 35 moves and comes into contact with the electrode bands 32 and 32 ', the cockroach receives a large electric shock and escapes.

In view of the above, the present inventors have considered a means for preventing the cockroaches from entering the cabinet 36 by attaching an electrode assembly 37 to the opening edge of the cabinet 36 as shown in FIG. .

Problems to be Solved by the Invention By the way, in the electrode structure 37, an insulating band 38 is provided at an intermediate portion, and electrode members 39 and 39 'are arranged in two lines on both sides thereof.
Are bent at 90 ° by V-cut at the end of the electrode assembly 37.
Together, 41 constitutes a framework. A voltage is applied to the electrode bands 39, 39 'from the power supply 43 via the lead wires 42, 42', and an electric shock is applied to the cockroach 35 which is going to pass therethrough to prevent the cockroach 35 from entering. is there.

However, the end 41 of the electrode assembly 37 may slightly shift during the butting operation. In this case, the outer electrode band 39 (the positive pole in FIG. 6) and the inner electrode band 39 ′ (the (Negative pole in FIG. 6) contacted to cause a short-circuit, and the insect repellent effect could not be exhibited.

Further, if a dimensional error occurs between the frame dimensions of the electrode assembly 37 and the frame dimensions of the opening edge of the cabinet 36, a gap may occur at the joint of the end portions 41 or the frame of the electrode assembly 37 may be located outside the cabinet 36. In some cases, it protruded, and there were problems in appearance and performance.

The present invention has been made in view of the above problems, and provides an electric shock type insect repellent device having good quality stability and appearance.

Means for Solving the Problems In order to achieve the above object, the present invention has an elastically deformable insulating member interposed between butted portions of electrode strips.

In this way, even if the abutting portion of the electrode band is misaligned, the insulating member prevents the positive and negative electrodes of the electrode assembly from coming into contact with each other, thereby preventing a short circuit. Even if a dimensional error occurs between the electrode strip and the container, the insulating member can be buried without a gap due to its elastic deformation characteristics, so that cockroaches do not enter through the gap and the appearance is improved.

Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

In the figure, 1 is a cabinet for storing articles, 2 is an electrode assembly disposed around the opening 1a of the cabinet 1, 3 is a door for opening and closing the opening of the cabinet 1, and 4 is a power supply composed of a dry battery or the like. The electrode assembly 2 has a band shape having an insulating band 5 at an intermediate portion and two electrode bands 6, 6 'on both sides thereof. For example, an insulating resin is used as the insulating band 5, and an electrode band 6, 6 'may be a composite integrally extruded and formed using a conductive resin containing carbon particles.

The electrode assembly 2 forms a rectangular frame by cutting the corner 7 into a V-shape and bending it by 90 °. Here, a flexible insulating member 8 made of foamed rubber or the like is fitted into the butting portion A at the end of the electrode assembly 2 and attached to the cabinet 1 with an adhesive or the like.

The voltage of the power supply 4 is applied to the electrode strips 6, 6 'through the lead wires 9, 9'.

Here, when the cockroach 10 comes into contact with the electrode strips 6 and 6 'in an attempt to enter the cabinet of the cabinet 1, the voltage of the power supply 4 is applied to the cockroach 10, and the cockroach 11 receives an intense electric shock, and is dissipated. Intrusion into the storage can be prevented.

In the above-described configuration, even when the butting portion A is displaced when the front pole assembly 2 is mounted, the insulating member 8
Are interposed between the butting portions A, so that the outer electrode band 6 (positive pole in the figure of the embodiment) and the inner electrode band 6 ′.
Can be maintained without contact and short circuit, and the performance can be maintained. In addition, the frame dimensions of the electrode assembly 2 and the frame dimensions of the opening edge of the cabinet 1 may have dimensional errors due to variations in processing dimensions and the like. In particular, when a resin material is used for the electrode assembly 2, the gap C of the butted portion A of the electrode assembly 2 opens or closes due to expansion and contraction of the material due to a temperature difference, contraction of the material due to aging, and the like. May change.

At this time, the insulating member 8 interposed in the butt portion
Since the insulating member 8 is made of an elastic soft insulating material, the insulating member 8 expands and contracts in response to the dimensional change of the gap C as described above, so that the insulating member 8 always fills the gap C, Cockroaches can be prevented from entering, and the appearance is extremely good.

In the figure, the thickness of the insulating member 8 is formed higher than the surface of the electrode assembly 2 by the dimension h. This is because when the door 3 is closed, the dimension h becomes the cushion allowance and the door 3
This is because the sealing member 8 is in close contact with the back surface and has a sealing property, whereby a gap is formed between the insulating member 8 and the door 3 and the cockroach 10 can be prevented from entering from this portion.

3 and 4 show another embodiment of the present invention, in which the cabinet 1 has an L-shaped opening 1a, and the left and right electrode structures 2 are provided at the corners of the L-shaped opening 1a. Are mounted at right angles to each other via an insulating member 8 having cushioning properties. The insulating member 8 is set higher than the surface of the electrode assembly 2 by the dimension h.

Also in this case, the butted portion A of the electrode structure 2 has the same effect as described above.

Effect of the Invention As is clear from the description of the embodiment, when the present invention is used to butt an electrode band for insect control around an opening of a cabinet or the like, an insulating member is interposed between butt portions of electrode band ends. Since the electrical insulation is reliable, and the insulating member is elastically deformable, even if a dimensional error occurs between the electrode band and the housing, the insulating member absorbs the dimensional error and absorbs the dimensional error. There is no gap between the end portions, the insect repellency can be further improved, and the appearance is good.
