In the present embodiment, the chamber portion 15 is directly extended to the upper side of the water (that is, a pipe material such as a vinyl chloride pipe constituting the chamber portion 15 is extended to the upper side of the water as it is). It is used as
A filter 31 is also provided in the middle of the duct 30, and insects captured in the chamber portion 15 are not captured by the filter 31 and are not re-released through the suction blower 12.
Further, the suction blower 12 is provided with a control device 32 for controlling its operation / stop. In addition to being able to perform any manual operation, the control device 32 in the present embodiment can operate the suction blower 12 intermittently, for example, only in a desired time zone by a preset desired timer control or program control. Thus, it is possible to perform control such that the automatic operation is performed in conjunction with the opening / closing operation of the shutter 3 (that is, the suction blower 12 is always operated when the shutter 3 is opened). Of course, if necessary, the suction blower 12 can be operated continuously at all times, and when other insect intrusion prevention devices are arranged side by side, control is performed so as to operate in conjunction therewith. Is also possible.

  Furthermore, the insect intrusion prevention apparatus A according to the present embodiment is provided with a cleaning mechanism 40 for supplying the cleaning mechanism 11 with chemicals such as cleaning water and disinfecting liquid and cleaning it. The cleaning mechanism 40 in the present embodiment is configured to spray cleaning water from a cleaning water tank 41 through a supply pipe 42 to the middle of the duct 30 by a nozzle 43, and the cleaning water is discharged from the duct 30 into the chamber 15 and the drain pipe 20. It is supposed that the inner surface is washed away and cleaned. In addition, what is necessary is just to mix the chemical | medical solutions 44, such as disinfection liquid, with cleaning water as needed. The washing water supplied by the washing mechanism 40 is led from the drain pipe 20 to the drain pit 22 and led from the drain pit 22 to the treatment apparatus by the discharge pipe 23, and finally, an appropriate drainage treatment is performed as necessary. It will be released later.

  According to the insect intrusion prevention apparatus A of the present embodiment configured as described above, when the suction blower 12 is operated, the suction blower 12 serves as an upper opening of the slit portion 14 through the chamber portion 15 and the slit portion 14. Air near the floor surface 2 is sucked from the suction port 13 to form a suction air flow 18, so that insects in the vicinity of the suction port 13 can be sucked by the suction air flow 18 and captured in the chamber portion 15. . Therefore, as long as the suction blower 12 is operated, insects cannot pass through the suction port 13 and cannot reach the entrance 1, so that entry from there can be reliably prevented. Of course, it is impossible for the captured insects to escape from the slit portion 14 until the suction air flow 18 is resisted, and filters 26 and 31 are provided before and after the chamber portion 15, respectively. Therefore, it cannot escape to the drain pit 22 or the suction blower 12 side, and will eventually die in the chamber portion 15 eventually.

  In particular, in the insect intrusion prevention apparatus A of the present embodiment, the upper opening of the slit portion 14 as the suction port 13 is processed into a bell mouth shape, so that the suction air flow 18 necessary for sucking insects is surely and reliably. Since the folded portion 17 is formed on both sides of the suction port 13 so that the hook portion 16 is folded back as a smooth curved surface, it is possible to prevent the insects from clinging to it, thereby making the insects more It can be surely inhaled.

In addition, since the suction port 13 is open to the floor surface 2, for example, inflow of rainwater or inflow of cleaning water at the time of floor cleaning is assumed, but the insect intrusion prevention apparatus A of the present embodiment has a chamber. A water gradient is secured in the portion 15 and a water drain pipe 20 is provided under the water and connected to the drain pit 22 via a water sealing mechanism 21, so that water can be drained without any trouble and water washing. Cleaning with can also be performed easily.
Moreover, since the cleaning mechanism 40 for supplying cleaning water or chemicals to the capture mechanism 11 for cleaning is provided, the cleaning mechanism 40 can perform cleaning operations periodically or as needed, The inside of the capture mechanism 11 can be easily and reliably cleaned and can always be maintained in a sanitary manner, and can be prevented from being clogged with dust and foreign matter.

  As described above, according to the insect intrusion prevention device A of the present embodiment, it is possible to surely prevent the invasion of insects traveling along the floor surface 2, and this is, for example, described in Patent Document 1 and Patent By installing it outside the doorway 1 in combination with other insect invasion prevention devices such as conventional air curtains and air showers as shown in Document 2, the floor surface 2 which was a weak point of these conventional devices can be obtained. It is possible to sufficiently supplement the prevention of invasion of transmitted insects and to realize the perfect prevention of invasion.

It is good to comprise so that it can connect with the inspection port 27 with the flange 45, and can disassemble suitably.

  In the above embodiment, a water gradient is secured in the chamber portion 15 for draining water, and the drainage pipe 20 and the drainage pit 22 are provided on the lower side of the chamber. However, there is absolutely no concern that water such as rainwater flows into the chamber portion 15. In addition, when there is no need to consider washing with washing water or chemicals, that is, when there is no particular need to consider draining, the draining pipe 20 and the drain pit 22 may be omitted.

  In the above embodiment, the filters 26 and 31 for capturing the captured insects are provided at the front and rear, and maintenance is performed in the drainage pit 22 or by disassembling the duct 30, but not necessarily The necessity of the filters 26 and 31, the installation position, the configuration for maintenance thereof, and the like can be changed as appropriate. In addition, it is conceivable to provide a trap mechanism such as various insect collectors in place of a simple filter. Further, a mechanism for attracting insects to be captured or killing captured insects is added. It doesn't prevent that either.

  In the above embodiment, the cleaning mechanism 40 is provided, and the cleaning mechanism 40 is configured to spray cleaning water and chemicals into the duct 30 from the nozzle 43 provided on the water side of the chamber portion 15. Alternatively, in addition to this, it is also conceivable that the cleaning mechanism is configured to spray or wash the cleaning water or the chemical solution on the entire capture mechanism 11 including the slit portion 14 and the drain pipe 20. However, in the case where it is assumed that the cleaning operation is performed by other means or other methods, it is not always indispensable to have the cleaning mechanism 40 as in the above embodiment, and may be omitted. Is possible.

Insects entering the route must be prevented by other means. Therefore, as described above, the insect intrusion prevention device of the present invention complements other devices such as air curtains and air showers. It is realistic to use with and should usually be like that.
However, there is no need to consider intrusion from other routes at all, and in the case where only intrusion from the floor surface needs to be considered, it does not preclude the use of the device of the present invention alone. Conversely, if necessary, the apparatus of the present invention may be provided not only on the floor surface but also on the wall surface and ceiling surface. In such a case, insects entering not only the floor surface but also the wall surface and ceiling surface may enter. Can also be effectively prevented.

Moreover, considering the combination with other devices such as an air curtain and an air shower, it is preferable to install outside the entrance as in the above embodiment, but instead, it can be installed inside the entrance, or even It is also possible to install double on both the outside and inside of the entrance / exit. In that case, even if it can pass through the entrance / exit, it will be captured immediately after that, and it will not be possible to enter the compartment that should be kept clean.
Furthermore, the apparatus of the present invention is not only installed at the entrance to the building from the outside, but also in the building where the interior of the building is partitioned and an area to be kept clean such as a clean room is provided. Needless to say, it can also be provided in the same way with respect to the entrance to the provided compartment.
