The solenoid 32 which moves the said shielding plate 29 is provided in the said electrical chamber 11.

The solenoid 32 is a single-acting linear solenoid having a plunger 33.

A spring 34 is provided for returning the plunger 33 when the solenoid 32 is not energized. In this embodiment, a compression coil spring is illustrated as the spring 34. This spring 34 is provided between the shielding plate 29 and the bottom face 7. Specifically, it is provided between the guide rail 30 and the shielding plate 29 attached to the bottom surface 7.

As shown in Figs. 4 and 5, the shielding plate 29 is made of stainless steel plate formed in a substantially square shape in plan view. The shielding plate 29 has a plurality of openings 35 arranged in the same pitch and in the same shape as the slit-shaped exhaust port 28 of the bottom face 7. As the shielding plate 29 moves in the P and Q directions (front and rear directions) of FIG. 4, the exhaust port 28 of the bottom surface 7 and the opening 35 of the shielding plate 29 coincide or disagree. The exhaust port 28 is opened and closed freely.

Position adjustment of the guide rail 30 is carried out by attaching the bolt 46 for attaching the guide rail 30 to the bottom face through the long hole 47 (refer FIG. 2) provided in the bottom face, As much position as possible.

By adjusting the position of the guide rail 30, the strength which the said spring 34 adds to the said shielding plate 29 is made to adjust freely.

In addition, the structure which adjusts the strength of the said spring 34 is not limited to what is shown to the said embodiment.

Next, operation | movement of the pest control apparatus of the said structure is demonstrated.

First, the lid 22 attached to the rear surface 3 of the casing 1 is dismantled, and the cartridge 25 of the chemical agent is stored in the chemical container 24 provided in the lid 22, and then the rear surface ( The lid 22 is attached to the opening 21 of 3) and locked by the key 23.

In this pest control device, in the daytime non-operational time, the exhaust port 28 is closed by the shielding plate 29, and the electrical equipment, such as the fan 12, is also turned off by the timer. The exhaust port closed state of the shielding plate 29 is held by the spring 34.

Since the exhaust port 28 of the bottom face 7 of the lower part of the chemical | medical agent chamber 10 is closed, convection does not generate | occur | produce in the chemical | medical agent chamber 10, and the chemical | medical agent vaporized from the plate 26 accommodated in the said chemical | medical agent chamber 10. Does not leak out of the casing 1.

When the night operating time is reached, a timer is activated to energize the solenoid 32, the plunger 33 is attracted to the electromagnet 36, and moves, and the shielding plate 29 engaged with the plunger 33 is moved. The opening 35 of the shielding plate 29 and the exhaust port 28 of the bottom face 7 coincide with each other, and the closed exhaust port 28 is opened to communicate the inside and the outside of the chemical chamber 10.

Electric appliances, such as the fan 12, the heater 19, and the temperature sensor 20, operate | move by a timer.

By the operation of the fan 12, outside air is received from the inlet port 27 into the electrical equipment chamber 11, and the air reaches the chemical chamber 10 while cooling the electrical equipment in the electrical equipment chamber 11. The air in the chemical chamber 10 sent by the fan 12 passes between the plates 26 of the cartridge 25 and is discharged from the exhaust port 28 to the outside including the pesticidal component vaporized from the plate 26. do.

At this time, the magnitude of the output of the heater 19 is adjusted based on the air temperature in the vicinity of the exhaust port measured by the temperature sensor 20 by the temperature controller of the electrical component, and an appropriate temperature. Here, an appropriate temperature means the temperature of a range which the concentration of the pesticide component in the air can become an effective value for pest control.

In this state, pests are controlled by spreading the insecticide component into the kitchen for a predetermined time. When the operation time elapses, the timer operates to stop the energization of the electrical equipment. When the energization to the solenoid 32 is stopped, the shielding plate 29 is added to the spring 34 to move to the position which closes the exhaust port 28, and closes the exhaust port 28. As shown in FIG.

In addition, in the said embodiment, although the intensity | strength of the spring 34 was adjusted freely, the suction force of the said solenoid 32 can also be electrically adjusted freely.

That is, the drive force adjustment device which adjusts the strength of the solenoid 32 can be provided in the said electric chamber 11.

Although not shown, this driving force adjusting device rectifies and charges the alternating current supplied from an external power source into direct current, charges it, and applies a DC voltage to the solenoid to convert a commercial external power source into a low voltage, a rectifier charging circuit, and an output. A constant voltage circuit in which the voltage to be adjusted is adjustable, a time limit circuit for synchronizing with fan driving, and a driver for driving the solenoid are provided.

The rectifier charging circuit includes, for example, a rectifier for rectifying and converting an alternating current voltage converted by a transformer into a direct current, a capacitor for charging and smoothing the direct current, and a three-terminal IC provided with a radiator.

The constant voltage circuit includes a three-terminal regulator having a zener diode, a transistor, a fixed resistor, a variable resistor, a protection circuit, and the like, a radiator provided in the regulator, and a stabilizing capacitor. A sufficiently accumulated charge flows through the zener diode due to voltage breakdown, and the voltage outputted according to the divided voltage of the fixed resistor and the variable resistor can be adjusted.

The time circuit constitutes a part of a timer mounted on the electric equipment, and synchronizes with the operation of the solenoid and the operation of the fan, in conjunction with the time circuit for driving the fan mounted on the electric equipment. That is, if the time circuit detects the output current from the constant voltage circuit at the start of operation of the pest control device by the timer, a drive signal is sent to the time circuit for driving the fan, and the solenoid drive and the fan drive are simultaneously executed. Can be.

The driver applies a predetermined voltage to the solenoid. As a result, a voltage having a predetermined magnitude is applied to the solenoid.

In the above configuration, the alternating current of the external commercial power source is converted into a predetermined voltage in the transformer, and the DC is charged and charged in the rectifying charging circuit, so that the constant voltage circuit is maintained at a relatively large voltage of, for example, about 48V. In this case, for example, when the solenoid has a rated voltage of 24 V, a resistance of 200 Ω and a rated current of 120 mm A, if a voltage of 48 V is applied to the solenoid by a driver, a current of about 240 mm A flows in the solenoid, The driving force is almost doubled. However, such voltage application is performed for a short time in order to avoid burnout.

Here, by adjusting the voltage in the constant voltage circuit, the magnitude of the voltage applied to the solenoid is changed, so that the driving force of the solenoid can be made variable.

According to the said embodiment, the inside of the casing 1 is partitioned back and forth by the partition 9, one is made into the chemical | medical agent chamber 10, the other is made into the electrical equipment chamber 11, and the outside air is said Since the fan 12 is introduced into the casing 1 and discharged outward from the electrical equipment chamber 11 to the outside via the chemical chamber 10, the height of the device is higher than that of the conventional electrical equipment chamber. It can be suppressed low and the compactness can be aimed at.
