Abstract

PROBLEM TO BE SOLVED: To provide a termite-proofing device applicable to a construction such as an existing house, with little power consumption. SOLUTION: This termite-proofing device is provided with an electrode 1 laid at a foundation part 2 of a construction which is an entry path of termites T, and a voltage applying means for applying only voltage to the electrode 1. Surge voltage of about 30 V having no influence on a human body or the like is applied to the electrode 1 by the voltage applying means. Since surge voltage includes high frequency, weak high frequency is radiated from the electrode 1, and the termites T approaching the electrode 1 are beaten off by the high frequency. The termites getting through high frequency to approach the electrode 1 receive an electric shock to die or take evading action. Since only the surge voltage is applied to the electrode 1, there is no anxiety about an electric leakage, and power consumption is little.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a termite control apparatus for preventing termites from entering buildings such as houses.

[0002]

2. Description of the Related Art Since various woods are used for outer walls and pillars of houses and the like, they are greatly damaged by termites. In order to prevent termites from invading, there is a method to improve the ventilation and ventilation under the floor to make it difficult to inhabit and nest the termites. Methods of making nesting difficult, methods of disinfecting the soil under the floor with chemicals, impregnating the wood with the chemicals, and performing repellent behavior or killing the drugs are being carried out.

[0003] Each of these methods is considered to be an effective termite-controlling treatment, but the fact is that the chemicals have an adverse effect on the human body and the measures are cumbersome, so that the practice has not been perfected. On the other hand, termites in Japan have a habit of invading houses from underground, so it is particularly effective to take measures to prevent them from entering the passage.

[0004] As a conventional measure for preventing termite invasion, for example, there is a termite prevention method disclosed in Japanese Patent Application Laid-Open No. 60-168334. The termite mitigation method is applied to a house having a steel frame composed of a steel frame such as a base, a column, a beam, a braced structure, or the like, which is harmless to a human body.
By passing a weak DC current of about 50 mA or less, termite inhabitation and nesting are prevented.

[0005]

However, the termite control method described in Japanese Patent Application Laid-Open No. Sho 60-168334 requires a house to be a steel frame as a prerequisite. And it is difficult to construct an existing house.

The termite control method is a method in which termite control is performed in a state where a weak DC current is applied. Therefore, even when a weak DC current of about 150 mA or less is applied, a considerable amount of power is always supplied. You are consuming.

In view of the above, the present invention provides an ant-control apparatus which can be applied to a building such as an existing house and consumes less power.

[0008]

The termite control device of the present invention comprises: an electrode laid on a foundation of a building which is a path through which termites enter;
A voltage applying means for applying only a voltage to the electrode. If termites come into contact with the electrodes to which only voltage is applied, they will receive an electric shock and will die or shock, and will be prevented from approaching or invading the structure, preventing the termites from nesting and nesting. This can be prevented. In addition, the electrodes are insulated by a transformer or the like and only the voltage is applied, so there is no fear of electric leakage, and in the normal state, there is almost no power consumption because no current flows.

The electrode laid on the base portion is preferably a strip-shaped conductor provided with one surface exposed on a strip-shaped insulator. The band-shaped insulator insulates the base of the building from the electrodes, and exposes one side of the conductor that is the entry path side of the termites. Electric shock can be caused. In addition, since the electrodes are strip-shaped, termites cannot cross over the electrodes, so that approaching or intrusion of termites into a building can be more reliably prevented.

Electrodes can be formed by baking a conductor on bakelite or the like used as a substrate of an electronic device. However, since no special skills are required for construction and maintenance, electric wires and the like are required. It is preferable that one surface of the conductor is exposed, and a strip-shaped combination formed in several stages is adhered to the base portion without gaps.

As the insulator, a material such as bakelite or vinyl can be used, but it is desirable to use vinyl particularly in consideration of cost, construction and the like.

The electrode is preferably wound around the inner wall of the foundation at the outer edge of the building and the peripheral wall of another foundation. The outer wall side of the foundation portion of the outer edge of the building has a lower year-round humidity than the inner wall side, so that it is difficult for the termites to enter the route. Therefore, by wrapping electrodes around the peripheral wall of the foundation, the path of entry of termites is cut off, and it is possible to reliably prevent the approach and invasion of termites into the building Become.

The voltage applying means may be a means for directly applying a voltage of several volts with a transformer or applying a pulse, but it is particularly preferable to apply a surge voltage. The surge voltage has the same properties as the voltage generated when the motor or the electromagnetic device is started, and has features such as a narrow pulse width, low power, and high voltage. In addition, since the electrode contains a high frequency, a weak high frequency is radiated from the electrode. Therefore, termites approaching the electrode are firstly repelled by the high frequency, and termites approaching by dipping under the high frequency can be repelled by being electrocuted by the surge voltage.
