FIG. 3 shows a case in which the cleaning brush 23 is moved in a direction for sweeping the insects dropped on the receiving tray 6, that is, in a direction toward the opening 12 side. The stopper 26a moves the entire cleaning brush mechanism 17 toward the opening 12 while pressing the inclined surface of the L-shaped cleaning brush 23 against the pan 6 from the outside.

After the cleaning brush 23 is moved toward the opening 12, the motor 14 is rotated in the reverse direction so that the stopper 26b of the wire 16 is moved (as shown by the phantom line in FIG. 1).
The entire cleaning brush mechanism 17 is moved in the direction opposite to the opening 12 while pushing up the inclined surface from the inside. At this time, since the cleaning brush 23 is lifted upward, it does not sweep the inner surface of the tray 6.

Further, in order to facilitate the drop of the insects into the insect trap bag 13, suction is performed by a suction blower 27 provided on the side of the insect trap room 10. The suction by the suction blower 27 is performed, for example, as shown by an arrow in FIG.
This is done via a ventilation channel that passes below the sides of the ten.

Further, below the tray 6, a high-voltage power supply section E, a counting means F and a control means G, which will be described in detail later, are provided (see FIG. 6). The frame 1 is covered so as to cover other parts except for the induction lamp 3 and the electrodes 4a and 4b.
33 are provided. The cover 33 is formed with air insertion ports 34. As shown in FIGS. 1 and 4, the cover 33 is provided with a control panel 35 connected to the high-voltage power supply E, the counting means F, and the control means G.

Thus, the automatic insect trap according to the present invention has the structure shown in FIG.
As shown in FIGS. 4 and 6, the inducing lamp 3 being turned on is temporarily turned off and turned on again to increase the stimulus to insects. More specifically, the control means G activates the collecting means 7 at each set cleaning time and sets the inducing light 3
May be turned off, and the attracting light 3 may be turned on again after the collection means 7 is stopped, or the attracting light 3 may be temporarily turned off at a fixed cycle regardless of the cleaning set time. . The high-voltage power supply E is turned on for the induction lamp 3
-You may make it ON / OFF in synchronization with OFF.

In this automatic insect trapping apparatus, the counting means F
Detects and counts the number of discharges of the electrodes 4a and 4b, and the detection signal from the counting means F is input to the control means G. The high-voltage power supply unit E is configured to be turned off. Further, the electrodes 4a, 4b are
Is variable, and the luminous intensity of the induction lamp 3 is adjustable. The voltage can be adjusted at the knob 37 on the control panel 35, for example, 2300V (low), 2500V (medium), 2700V
V (high) can be switched to three stages. The luminous intensity of the induction lamp 3 can be adjusted within a predetermined luminous intensity range by a knob 38 of the control panel 35.

More specifically, in the high voltage power supply section E,
After the output of the inverter circuit 41 connected to the AC commercial power supply is boosted by the pulse transformer 42, the output of the rectifier circuit 43
And is supplied to the electrodes 4a and 4b. That is, DC current is supplied from the high voltage power supply unit E to the electrodes 4a,
4b. Inverter circuit 41 includes control means G
And the safety circuit 45 is connected, and the input end of the safety circuit 45 is connected to the guard 11. The safety circuit 45 sends a stop signal to the inverter circuit 41 when a person touches the guard 11 and the limit switch is operated. The inverter circuit 41 stops operating in response to the stop signal.

The counting means F is configured as follows. A Rogowski coil is connected to the ground end 44 of the rectifier circuit 43.
An output is sent to a counter circuit 53 via a current detection circuit 52. The counter value of the counter circuit 53 is displayed on the counter display section 36 of the control panel 35. The current detection circuit 52 is connected to the control means G and outputs a detection signal to the control means G by detecting a discharge between the electrodes 4a and 4b.

The control means G determines how often the collection means 7 should be operated to clean the drive when the power switch 46 of the control panel 35 is turned on (cleaning set time).
And a knob 40 of the timer can be set in accordance with a desired set time. In the present embodiment, a case where the timer can be set in units of 10 minutes up to 60 minutes is illustrated. If the knob 40 is set to the position of the indication "cleaning", the collecting means 7 can be operated at any time.

The knob 39 of the control panel 35
This is for adjusting how many seconds the high-voltage power supply unit E is turned off immediately after the discharge between the electrodes 4a and 4b. For example, the count intervals can be set to 1.5 seconds, 5 seconds, 20 seconds, and 45 seconds. The control means G controls the high-voltage power supply unit E so that the high-voltage power supply unit E is turned off for a set period (count interval) immediately after the discharge between the electrodes 4a and 4b. That is, after the count interval, the high-voltage power supply unit E is turned on again.

FIG. 5 is a time chart of the collecting means 7, the induction lamp 3 and the high-voltage power supply section E when the automatic insect trap is driven. The operation of the automatic insect trapping apparatus will be described with reference to FIGS. 1 to 5. Turning on the power switch 46 of the control panel 35 to start driving causes the induction lamp 3 and the high-voltage power supply unit E to be in the ON state. Becomes That is, the induction lamp 3 is turned on, and a high voltage is applied to the electrodes 4a and 4b from the high-voltage power supply unit E to perform insect trapping.

When a cleaning set time has elapsed (for example, 60 minutes have elapsed) from the start of driving, the motor 14 is driven by the control means G, and the cleaning brush mechanism 17 is reciprocated in the receiving tray 6 a preset number of times. The insect corpse is moved to the opening 12 by the operation 23, and the suction blower 27 is operated at the same time, so that the insect corpse is effectively collected in the insect trapping bag 13. During this cleaning time, even if the control means G synchronizes so that the induction lamp 3 is turned off and turned off and the high-voltage power supply unit E is turned off and the output to the electrodes 4a and 4b is stopped. good. Further, the attraction lamp 3 may be set to be turned off once and a plurality of times and turned on again before the cleaning time. For example, after the light is turned on for 10 minutes, the light is turned off for 1 minute, and this is repeated.

By the way, during the insect catching time from the start of driving to the start of cleaning, insects attracted by the induction lamp 3 and gathered around the insects come close to or come into contact with the electrodes 4a and 4b and receive an electric shock. Fall to 6. The discharge at this time is usually a current that hardly flows, but is instantaneous, but from 10 mA to 1 mA.
Reaches 00 mA. Then, immediately after the discharge, the high-voltage power supply unit E is instantly turned off, and then turned on again after a set count interval (for example, 20 seconds). In other words, a state is obtained in which the electric shock is effectively applied but no continuous discharge occurs.

As described above, during the insect catching time, when a plurality of insects approach or contact the electrodes 4a and 4b, the high-voltage power supply unit E is turned off and turned on again for each of a plurality of discharges.
However, since a strong electric shock is applied to the insect without generating a continuous discharge, the insect falls between the electrodes 4a and 4b without scorching, thereby preventing the insect from adhering to the electrodes 4a and 4b. At this time, when a relatively small insect (for example, a mosquito or a small fly) is targeted, the counting interval is increased to 20 seconds or 40 seconds. If you are targeting relatively large insects (such as fly or beetle) that do not scorch and are unlikely to adhere to them, shorten the counting interval to 1.5 seconds or 5 seconds. The count interval can be switched according to.

The attracting light 3 is set to have a high luminous intensity for insects with poor running properties (for example, large fly), and the luminous intensity is set for insects with good running properties (for example, file mosquitoes). The luminous intensity (brightness / darkness) is adjusted according to the nature of the insects, such as setting it low, or according to the brightness of the installation location.

Further, by adjusting the electric shock voltage applied to the electrodes 4a and 4b to an appropriate intensity, it is possible to prevent the insect wings and legs having a soft skeleton from scattering due to the electric shock. In this way, it is possible to prevent the insect wings and legs from being scattered by electric shock and entering the food stored in the installation place (for example, a food processing plant), and to prevent the insect wings and legs from being scattered. It is possible to prevent the secondary pollution that other insects gather and multiply for eating.

The discharge current between the electrodes 4a and 4b is detected by the Rogowski coil 51 and the current detection circuit 52, and the number of times is counted by the counter circuit 53. The count number of the counter circuit 53 substantially corresponds to the dead body of the insect.

As described above, the automatic insect trapping device of the present invention temporarily turns off the lit induction lamp 3 to increase the stimulus to the insect, thereby effectively attracting the insect and sparking while keeping the electric shock force strong. A high voltage is applied between the electrodes 4a and 4b while setting a predetermined count interval for each discharge so as to prevent the discharge from being continued, thereby killing the insects by electric shock and operating the collecting means 7 at every set cleaning time. The insects that fell into the saucer 6
Can be collected inside.

As shown in FIG. 7, the automatic insect trapping apparatus of the present invention may be arranged such that a plurality of electrode groups 29 are independently controllable and arranged near the induction lamp 3. That is,
For example, three electrode groups 29, 29, 29 are arranged above, in front of, and below the induction lamp 3, with a plurality of pairs of electrodes 4 a, 4 b as one group. Openings 30 for taking in insects are provided on the upper wall, the front wall, and the lower wall of the cover 33. Although FIGS. 1 to 6 show a case in which control is performed while supplying a direct current to one electrode group, such a circuit configuration is applied to a plurality of electrode groups.
29 ... so that they can be controlled independently.

According to this automatic insect trapping device, for example, when an insect approaches or touches the electrodes 4a and 4b of the upper electrode group 29 and a discharge occurs, the discharge at the electrode group 29 is counted.
In addition, the current supply is stopped at the predetermined count interval (as described above), but the current supply is continued for the other front and lower electrode groups 29, 29 for independent control. Therefore, by recording the position where the discharged electrode group 29 is disposed and the number of times the current supply is stopped, the flying direction and the number of insects are detected, thereby detecting the direction from which the insect comes. You can know if there are many. At the same time, it is possible to obtain low power consumption and an effective electric killing effect. The arrow B indicates the flight direction of the insect.

The present invention is not limited to the above-described embodiment. For example, in the present embodiment, the case where the cleaning set time can be set in units of 10 minutes up to 60 minutes has been described. It may be configured such that a long set time that can be set up to the time is also possible. The setting of the count interval can be freely changed.

[0036]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first aspect of the present invention, the inducing lamp 3 being turned on is temporarily turned off and then turned on again, so that the stimulus to the insect (attracting effect) is enhanced, and more insects are attracted. Can be killed by electric shock. Temporarily turning off the light also reduces power consumption.

(According to claim 2) Insect electrodes 4a,
Immediately after the 4b discharge, there is no continuous discharge, so that the scorched carcasses of the insects adhere to the electrodes 4a and 4b as in the related art, eliminating the problem of causing a charge failure and the problem of the bad smell when scorching. Can be greatly improved in reliability.

According to the third aspect of the present invention, the electric shock voltage applied to the electrodes 4a and 4b can be adjusted to an appropriate intensity, so that the wings and legs of the soft insect skeleton do not fly around due to the electric shock. Can be That is, the beautification / sanitary state around the device can be favorably maintained. Therefore, it is possible to prevent the insect wings and legs from being scattered by the electric shock and being mixed into the food stored in the installation place (for example, a food processing plant), and to prevent the scattered insect legs from being eaten by other foods. It is possible to prevent secondary pollution in which insects gather and multiply.

According to the fourth aspect, the luminous intensity of the induction lamp 3 depends on the nature of the insects, such as insects having poor running performance (sensitivity to light) and good insects, or the brightness of the installation place. High and low (light and dark) can be adjusted.

(In accordance with claim 5) In order to independently control the plurality of electrode groups 29, even if one electrode group 29 discharges and the supply of electricity is stopped for a predetermined count interval, the other electrode groups 29 remain electrically controlled. Supply is continued, and low power consumption and an effective electric killing effect can be obtained. Further, the flying direction of the insects can be known from the discharged electrode group 29, and measures such as an electric shock can be made with emphasis on the direction where many insects come. (According to claim 6), an electric shock insect killing effect can be obtained efficiently with low power consumption compared to the alternating current.
