Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention sets a heating tool itself in which a heating element such as a hot water pipe or an electric heater is arranged on a panel, carpet, rug or tatami mat to a high temperature level for a set time. The present invention relates to a heat collecting tool with a pest control device for controlling harmful insects generated in the heat collecting tool.

[Prior Art] As a warming tool which has been used in recent years, there is a warming tool in which a heating element such as a hot water pipe or an electric heater is arranged on a panel, carpet, rug or tatami mat. .

However, pests are likely to occur around, above, or inside the heat collecting equipment that is laid and used mainly indoors on the floor surface, etc., and pests in the indoor dust breed due to moderate humidity and temperature, causing a problem. ing.

For example, mites are commonly inhabited as arthropods of the arachnids, and many mites such as Dermatophagoides farinae, Plutella xylostella mites, and Wicked mites are alive during the use of the heat collecting equipment.

Therefore, as a means for chemically controlling these mites, conventionally, linden, daeldrin, ferrtrotin, or
Drugs such as DDT are used.

Further, as a means for physically exterminating, there is a dielectric heating extermination method using microwave or high frequency, and as another means for exterminating harmful insects, a means for breeding or exposing the treated body to the sun is used.

However, the chemical pest control means has a drawback in that it has a slow-acting effect and that it is selective for the type of mites. However, there is a problem in that the secondary 8th position cannot be prevented, and that any of the above exterminating means requires a large-scale work.

Furthermore, with the means for exterminating insect pests by sun-drying, there are cases in which the sun-drying is impossible due to the time and effort required to breed or habitat the outdoors or the objects to be treated or the building environment, and there is the problem that simple means for exterminating insects cannot be obtained. .

Therefore, although the conventional means for controlling pests has a temporary effect of controlling insects, the insects immediately propagate, which leaves many problems causing human dermatitis and diseases.

[Problems to be Solved by the Invention]

The present invention has been made to solve the above-mentioned conventional problems, and can easily exterminate harmful insects generated in a heating tool itself provided with a heating element on a carpet or a rug by heat of the heating element. The problem to be solved is to provide a warming tool with a pest control device that can be used.

[Means for Solving the Problems]

As a means for solving the above problems, the heat collecting tool with a pest control device of the present invention is a heating element and a heating tool provided with a temperature control circuit for controlling the heating element to a constant temperature. By providing a timer circuit that operates for several seconds to several tens of minutes during disinfection and a high temperature level setting circuit that sets the control temperature of the temperature control circuit to a value selected from 35 ° C to 60 ° C by the output of the timer circuit Is configured,
The heat collecting tool itself is set to a high temperature level for exterminating pests for a predetermined time to exterminate pests.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 shows a circuit configuration diagram of one embodiment of a warming tool with a pest control device of the present invention. In the warming tool with the extermination device, the heating element 2 and the triac 3 are connected in series to the commercial AC power source 1, and the gate of the triac 3 is connected to the drive circuit 4. The output end of the drive circuit 4 is connected to the temperature control circuit 5, and one end of the temperature control circuit 5 is connected to one end of the heating element 2 via the silicon rectifier 6 and the resistor 7. A timer circuit 9 is connected to the commercial AC power source 1 in parallel with the heating element 2 and the triac 3.

On the other hand, the heating element 2 is a panel as an object to be processed (not shown),
It is placed on a carpet, a rug, or a warming tool such as a tatami mat. The thermistor 10 has a built-in thermistor 10 for detecting the upper surface or internal temperature.
Is connected to the temperature control circuit 5. In addition, the temperature control circuit 5 uses a timer circuit 9 to change the temperature of the heating element 2.
It is connected to the.

That is, in this embodiment, a heating tool having a heating element 2 and a temperature control circuit 5 for controlling the heating element 2 to a constant temperature is used, and a timer circuit 9 that operates for several seconds to several tens of minutes and an output of the timer circuit 9 are provided. Thus, a pest control device comprising a high temperature level setting circuit for setting the temperature control of the temperature control circuit 5 of the heating element 2 to a value selected from 35 ° C to 60 ° C is provided.

Next, the operation of the heat collecting tool with a pest control device having the above structure will be described. First, when the commercial AC power supply 1 is turned on by a switch or the like not shown, the supplied current causes the silicon rectifier to supply current. 6 through resistor 7,
The temperature control circuit 5 is activated, and a signal is input to the drive circuit 4 to activate the triac 3.

At the same time, the current from the commercial AC power supply 1 is applied to the heating element 2
Is also supplied to the heating device, the heating device is in a heating state, and in this state, a signal from the thermistor 10 turns on the triac 3.
When the heating element 2 is turned on and off by being turned off, the temperature is controlled to a constant temperature level A shown in FIG.

After that, at the time of exterminating pests such as ticks, by turning on the timer circuit 9 and a switch for exterminating pests (not shown),
When turned on, the heating element 2 is controlled to the high temperature level B by the operation of the temperature control circuit 5.

The timer circuit 9 is turned off at a set time selected from several seconds to several tens of minutes, and the heating element 2 is again operated at a constant temperature level C for heating by the operation of the temperature control circuit 5. Controlled.

This will be explained by a concrete example. Normally, when the timer circuit 9 is turned on while the surface temperature of the heating tool is kept close to 30 ° C., the surface temperature of the heating tool is set to 35 ° C. Electricity is applied for a few seconds or tens of minutes at a constant set temperature for exterminating insect pests selected from about 60 ° C.

For example, when controlling ticks, if the ON time of the timer circuit 9 is set to 1.4 seconds and the surface temperature is set to 50 ° C., the ticks will be in a lethal state.

Then, the timer circuit 9 is turned off after the elapse of the set time, and the heating element 2 is controlled at the normal temperature for heating.

The heat generating element 2 for the pest control device may be combined with the heat collecting tool as in the embodiment shown in FIG. 2, but it can also be incorporated into the heat collecting tool solely for driving pests.

For example, in the heating element 2 and the thermistor 10 which are independently incorporated in a tatami mat, a carpet, a rug, a panel, or the like, the timer circuit 9 is operated in the ON state when the ticks are removed. At that time, as shown in the other embodiment of FIG. 3, the warming tool is independently set to a high temperature level B, unlike a constant temperature level A due to the heat generated by the separately arranged heating element 2.

Needless to say, if a temperature sensor such as a ceramic semiconductor is connected to the temperature control circuit 5, the temperature can be controlled by detecting the humidity.

In addition, the humidity sensor is provided in the vicinity of the object to be exterminated or the object to be treated. In this way, when the heating element 2 reaches the high temperature level A, it heats the harmful insects, so that the harmful insects are in a lethal state. Further, it goes without saying that the warming tool does not perform warming in a high humidity condition such as summer, and even if it is a facility, it is possible to perform only pest control at a high temperature level.

〔The invention's effect〕

As described using the above examples, according to the warming tool with a pest control device of the present invention, since the heating element is energized at the high temperature level for a set time by operating the timer circuit, the safety is higher than that of the chemical treatment. It is expensive and easy to operate, and further has the effect of saving the trouble of carrying in processing equipment such as chemicals and extermination devices.

Further, the pests can be exterminated regularly and easily without carrying or moving the object to be treated such as tatami mat, carpet, rug or panel.

Therefore, the object to be processed can be used indoors even in seasons other than when heating is required.

Further, in the present invention, since the pests generated in the heat collecting tool itself can be exterminated by using the heating element provided in the heat collecting tool itself, it is necessary to provide another heat generating means for exterminating pests. There is also no effect, so there is also an effect that the cost of exterminating pests will be low.
