Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for exterminating pests using an electric carpet used for floor heating.

[Conventional technology] In general, tatami mats, carpets, rugs, etc. laid indoors are prone to infestation with pests such as dust mites and dust mites, and one way to exterminate such pests is to expose them to sunlight and exterminate them. However, it is said that sun-drying is a tedious extermination process and does not have sufficient insecticidal effects, and that it causes environmental pollution in kitchens, living rooms, etc. There was a problem.

Therefore, as a method for easily exterminating pests without causing environmental pollution, a method of exterminating pests using an electric carpet has been proposed.

For example, in JP-A No. 61-274642, by setting the temperature of an electric carpet whose temperature is controlled by a thermostat to a high temperature that can exterminate pests,
There was a pest extermination method that exterminated pests (mites) that lived on the parts to be exterminated (folding, carpets, rugs, etc.) under electric carpets.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, the temperature of the electric carpet is set near the maximum temperature, and the electric carpet is continuously energized for a suitable period of time to exterminate pests. Since the materials and heat retention properties of the parts to be exterminated under the electric carpet vary, simply setting the temperature of the electric carpet to a predetermined temperature does not know how much the parts to be exterminated will be heated. There has been a problem in that the temperature of the extermination member may become too high, causing it to discolor or change in quality.

Although it is sufficient to adjust the set temperature of the electric carpet by taking into account the material and heat retention of the parts to be exterminated, the user can adjust the temperature of the electric carpet by taking into account the material and heat retention of the parts to be exterminated. It was difficult to set up.

The present invention has been made in view of the above points, and its purpose is to easily and reliably exterminate pests using the heating element of the electric carpet body, and to
To provide a pest extermination method using an electric carpet and a device therefor, which can prevent discoloration and change of purchase due to overripe of exterminated members.

[Means for Solving the Problems] In the pest extermination method using an electric carpet of the present invention, an electric carpet equipped with a heating element is placed over a member to be exterminated, the temperature of the member to be exterminated is detected, and a temperature controller is installed. In addition, the apparatus according to claim 2 is configured to control the heat generation by the heating element so that the temperature of the member to be exterminated becomes the pest extermination temperature. It consists of a temperature detector that detects the temperature of the object to be exterminated below, and a temperature controller that controls the heat generated by the heating element so that the detected temperature of the object to be exterminated reaches the pest extermination temperature.

Furthermore, according to a third aspect of the present invention, the temperature controller is provided with a timer means that can variably set the operating time depending on the pest extermination temperature.

Furthermore, according to a fourth aspect of the present invention, a temperature sensor is detachably attached to a temperature controller provided in an electric carpet via a connector.

Furthermore, according to a fifth aspect of the present invention, the temperature controller is provided with an operation display section that displays a pest extermination operation display, a set operation time, and a remaining operation time.

Furthermore, if a timer means is provided which can variably set the operating time depending on the pest extermination temperature as in claim 3, pests can be reliably exterminated.

Furthermore, as in claim 4, if the temperature sensor is detachably attached to the temperature controller section of the electric carpet via the connector, the temperature sensor can be prevented from getting in the way during normal use. If the temperature controller section is provided with an operation display section that displays the pest extermination operation display, the set operation time, and the remaining operation time, the pest extermination operation status can be accurately grasped and usability can be improved.
