Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric insect repellent device for preventing the invasion of pests such as cockroaches that gather in a kitchen, two dining rooms, and a food storage room.

Structures of conventional examples and their problems Most conventional electric shock type insect repellent devices are constructed as shown in FIG. The insect repellent device 1 includes an insulating base material 3 and electrodes 5 and 6 of different polarities for electric shock, which are arranged substantially parallel to each other on the upper surface of the insulating base material 3 with a gap 4 in between. In addition, this electrode 5,
A voltage of about 10 volts is applied to the battery 6 by a dry battery 7.

It is known that insects such as cockroaches receive severe electric shocks when a voltage of about 10 volts is applied between their legs. Now, when the insect 8 tries to climb the wall 2 and its legs cross over the interval 4 and touch the surface of the electric current IfMs,e, a voltage is applied to the insect 8 and a current flows inside its body.
He receives a severe electric shock and falls downwards.

Therefore, if this insect repellent device 1 is placed around the vertical end face of the opening of the storage compartment 9 as shown in FIG. 2, it will give an electric shock to the insects 1o that try to enter the storage compartment and prevent them from falling. , can prevent intrusion. However, rooms such as the kitchen 2 and dining room where such an insect repellent device is installed are often humid, and especially in winter, dew condensation 11 may form on the surface of the insect repellent device 1 as shown in FIG. At this time, a voltage is applied to the electrodes 6, 6, and the attached dew 11
As a result, the voltage between the electrodes may drop and the dry cell battery 7 may become exhausted, resulting in the insect repellent function not being fully exerted.

OBJECTS OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks, and aims to provide a reliable insect repellent function even when used under adverse conditions.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes electrodes of different polarities for electric shock to which a low voltage is applied, which are arranged substantially parallel to each other with a gap between them, and an electrode of different polarity between the electrodes of different polarities. It has a configuration in which heater wires are arranged approximately in parallel with the above, and the above effect is obtained by evaporating the above condensed dew.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 4 to 7.

In FIG. 4, reference numeral 1-2 is an insect repellent device, which includes an insulating base material 13 made of synthetic resin material, etc., and a stainless steel strip material etc. arranged approximately parallel to the upper surface of the insulating base material 13 with a gap 14 in between. It extends from electrodes 15.16 of different polarities for electric shock and a heater wire 17 disposed between the electrodes 15.16.

A low voltage of about 10 volts is applied between the electrodes 15 and 16 by a dry battery 18 or the like, and a power source such as a dry battery 19 is connected to the heater wire 17.

Here, 20 is Nuinochi.

FIG. 6 shows an example of use in which the insect repellent device 1-2 is disposed around the vertical end face of the opening of the storage 21.

In the above configuration, assume that dew condensation has occurred on the surface of the insect repellent device 1-2 in a humid usage situation. At this time, when the heater wire 17 is turned on, the heater wire 17 generates heat, and this heat evaporates the dew that has adhered to the vicinity of the interval 14.
It is possible to stop current from leaking between the terminals 4', 15, and 16 through this dew.

As a result, the voltage drop between the electrodes J5 and 16 and the dry battery 18
This eliminates the wear and tear of the insects and allows them to perform their normal insect repellent function. In particular, since the heater wire 17 is arranged between the electrodes 16 and 16 in parallel with the electrodes, the dew deposited on the gap 14, which causes current leakage, can be quickly evaporated with a small amount of heat generation. be able to.

In the embodiment described above, if the switch 20 is always turned on, no condensation will occur near the electrodes 15 and 16, but since the battery 19 is consumed rapidly, when condensation occurs, the switch 2o is turned ON and the condensation is prevented. It is preferable to turn it off when it runs out.

Therefore, in the embodiment shown in FIG. 6, the insect repellent device 2 includes an insulating substrate 13, electrodes 15 and 16 of different polarities, and
The heater wire 17 and the dry battery 18 are similar, but the electrode 1
A dew condensation sensor 23 is disposed on a part of the surface between 5 and 16, and this dew condensation sensor 23 and a heater power supply device 24 are interlocked.

Now, if dew condensation occurs on the surface of the insect repellent device 2-2, the dew condensation sensor 23 detects the dew, and the heater power supply device 2-2 detects the dew.
ONL and evaporate the attached dew.

Further, when the dew evaporates and disappears, the heater power supply device 24 is turned off by a signal from the dew condensation sensor 23.

In the embodiment shown in FIG. 7, "2" is an insect repellent device, and the heater wire 17 is connected between the electrodes 15 and 16 of different polarities to the insulating substrate 1.
This is an example provided at the bottom of No. 3. In this case, heater wire 17
Although the efficiency with which the heat is transferred to the condensed dew and evaporated is a little lower than in the above embodiment, there is no fear that the heater wire will corrode or break due to external force.

Effects of the Invention As is clear from the above description of the embodiments, even when the electric insect repellent device according to the present invention is installed in a humid place, the function of the insect repellent device is not hindered by condensation, and dew condensation is efficiently removed. can be removed and exert sufficient insect repellent function.
