By the way, in insect invasion prevention devices such as air curtains and air showers as shown in Patent Document 1 and Patent Document 2, they adhere to insects that jump into the doorway and people and articles that pass through the doorway. Invasion of insects can be almost prevented, but invasion of insects traveling on the floor cannot always be sufficiently prevented.
In other words, this type of device prevents insects from invading by blowing away insects with a sufficient flow rate and airflow, but it is inevitable that the flow rate is usually greatly reduced near the floor surface. In particular, dead zones that do not reach the airflow may occur at the corners where the floor and the wall intersect, so insects (eg, rubber bugs, snails, black ants, The invasion of German cockroaches, black cockroaches, etc.) cannot always be sufficiently prevented.

  Therefore, the device shown in Patent Document 3 has been proposed, and it can be almost surely prevented from invading insects traveling on the floor surface by using it together with the air curtain and air shower as described above. Even in the case where insects are transmitted along the wall surface or along the corner between the floor and the wall, the prevention of intrusion is not necessarily perfect, and further improvement is desired.

  In view of the above circumstances, an object of the present invention is to provide an effective and appropriate device that can surely prevent the invasion of insects that try to invade through not only the floor surface but also the wall surface.

  The invention described in claim 1 is an insect intrusion prevention device for capturing and preventing insects entering the compartment to prevent insects from entering the floor or wall surface. In addition, a trapping mechanism configured to suck insects to be trapped through the slit and capture them in the chamber is installed over the entire width of the entrance at the outside or inside of the compartment, or both, and a suction blower is connected to the chamber The chamber in the capture mechanism is a floor chamber part installed under the floor across the entire width of the entrance and exit, and is connected to the floor chamber part and stands outside or in the wall part on both sides of the entrance and exit. The slit in the capture mechanism is integrally connected to the upper portion of the floor chamber portion, and the upper end portion thereof is connected to the floor suction port. The floor slit portion that is open to the floor surface and the wall chamber portion that is integrally connected to the side portion on the entrance / exit side and that is continuous with the floor slit portion, the tip of the wall chamber portion opens to the wall surface facing the entrance / exit The suction air flow is obtained by sucking air near the floor surface and the wall surface through the floor chamber portion and the wall chamber portion from both the floor slit portion and the wall slit portion by the suction blower. Insects traveling on the floor surface and the wall surface are sucked into the floor suction port and the wall suction port and captured.

  Invention of Claim 2 is an insect invasion prevention apparatus of invention of Claim 1, Comprising: The hook part extended to both sides at the front-end | tip part of the said floor slit part and the said wall slit part in the said capture mechanism, respectively And the cross-sectional shape of the floor suction port and the wall suction port becomes a bell mouth shape by forming the folded portion as a smooth curved surface.

Insects can be reliably prevented from entering the compartment that should be kept clean. Therefore, by using the insect intrusion prevention device of the present invention in combination with other insect invasion prevention devices such as an air curtain and an air shower, for example, the invasion prevention from the floor surface and wall surface, which has been a weak point of those conventional devices, In particular, the invasion prevention of insects traveling along the corners between the floor and the wall can be sufficiently complemented to realize the perfect invasion prevention.

In addition, by making the cross-sectional shape of the suction port a bell mouth shape, a sufficient and preferable suction air flow necessary for sucking insects can be reliably formed, and smooth ridges are formed as curved surfaces on both sides of the suction port. It is more effective because it can prevent insects from clinging there.
In addition, the floor chamber can be installed with a water gradient, and a drain pipe and drainage pit can be provided on the lower side of the floor, so that water can be drained from the capture mechanism without any trouble. By connecting to the drainage pit via the filter, it is possible to perform maintenance of the filter provided for catching insects from within the drainage pit without sanitary problems.
Further, if a cleaning mechanism for supplying a chemical solution such as cleaning water or a disinfecting solution is provided for cleaning, the collection mechanism can always be maintained in a sanitary manner.

An embodiment of the present invention will be described with reference to FIGS. The insect intrusion prevention apparatus according to the present embodiment is installed outside the entrance of a building (the inside of which is a clean section to prevent insects from entering). It is intended to prevent the entry of insects that are going to enter the building through the entrance and exit in front of the entrance.
This embodiment is based on the premise that other insect intrusion prevention devices such as air curtains and air showers are used in combination, so that the invasion of insects along the upper surface of the wall and the ceiling surface can be prevented naturally. Therefore, the main purpose of the apparatus itself of this embodiment is to prevent the intrusion through the floor surface and the lower part of the wall surface, and in particular, it is possible to reliably prevent the intrusion from the corner between the floor and the wall. Yes.

  1 to 3, reference numeral 1 denotes an outer wall of a building, 2 denotes an entrance / exit thereof, 3 denotes a shutter provided at the entrance / exit 1, and 4 denotes sleeve walls (wall portions) provided on both sides outside the entrance / exit 1. The insect invasion preventing device of the embodiment is installed at the position of the tip of the sleeve wall 4.

The insect intrusion prevention device of this embodiment is mainly configured by a capture mechanism 5 for capturing insects and a suction blower 6 (see FIG. 2) connected to the capture mechanism 5.
As shown in FIG. 3, the capture mechanism 5 is configured to suck insects to be captured from the suction port 7 through the slit 8 and capture them in the chamber 9, and in particular, the suction port 7 is used as the floor suction port. 7a and the wall suction port 7b, the slit 8 is composed of the floor slit portion 8a having the floor suction port 7a and the wall slit portion 8b having the wall suction port 7b, and the chamber 9 is made of the floor chamber portion 9a and the wall. It is comprised by the chamber part 9b.
That is, the capture mechanism 5 in the present embodiment has a wall chamber portion at each end portion of the floor chamber portion 9a which is longer than the distance between the sleeve walls 4 (that is, the width of the entrance / exit 1) and is installed below the floor surface. 9b is configured to be raised at a position outside the sleeve wall 4, a floor slit portion 8a is integrally connected to the upper portion of the floor chamber portion 9a, and the upper end thereof is opened as a floor suction port 7a on the floor surface. A wall slit portion 8b is integrally connected to a side portion of the chamber portion 9b on the side of the entrance / exit 1 and is connected to the floor slit portion 8a, and the end of the sleeve wall 4 facing the entrance / exit 1 is formed as a wall suction port 7b. The wall is open.
As described above, in the present embodiment, since the purpose is to prevent intrusion particularly from the corner between the floor and the wall, the wall suction port 7b is located on the lower part of the wall surface (for example, up to a height of about 20 to 30 cm above the floor surface). Therefore, the rising dimension of the wall chamber portion 9b from the floor chamber portion 9a may be set so that the wall suction port 7b can be formed in such a range. .

The floor chamber portion 9a is made of, for example, a pipe material such as a vinyl chloride pipe. As shown in FIG. 4, the upper portion of the floor chamber portion 9a is cut into a slit shape and the lower portion of the floor slit portion 8a is slightly inserted therein. They are connected together so as to be airtight.
The floor slit portion 8a is a flat and horizontally long cylindrical body made of a metal plate such as stainless steel or aluminum plate or a resin molded plate, and its upper end opens on the floor as a floor suction port 7a. However, the upper end portion of the floor slit portion 8a serving as the floor suction port 7a is folded back so as to extend to both sides, and a flange portion 10 is formed there, and is folded back to form the flange portion 10. The folded portion 11 has a smooth curved surface, whereby the cross-sectional shape of the floor suction port 7a is a smooth bell mouth shape, so that a sufficient and preferable suction air flow is naturally formed, and Insects are difficult to cling to the periphery of the floor suction port 7a.

Similarly, the wall chamber portion 9b is made of a tube material such as a vinyl chloride pipe, for example, like the floor chamber portion 9a, and one side portion thereof is cut into a slit shape as shown in FIG. The base end portion of the portion 8b is integrally connected so as to be able to be kept airtight in a state where it is inserted slightly.
The wall slit portion 8b is also a flat cylindrical body made of a metal plate such as stainless steel or aluminum plate or a resin molded plate, like the floor slit portion 8a, and the tip thereof is the same as the floor suction port 7a. The bell mouth-shaped wall suction port 7b is opened at the lower portion of the wall surface of the sleeve wall 4.

In addition, the shape and size of each part in said capture mechanism 5, especially the wind speed and volume of the suction air flow which should be ensured in suction port 7 (floor suction port 7a and wall suction port 7b), suction air pressure (maintained in capture mechanism 5) The specifications such as negative pressure should be set optimally in consideration of the type and size of the insects that are assumed to be captured, but it is assumed to be damselfly, kingworm, black ants, German cockroaches, black cockroaches, etc. If a suitable example is given, the width of the suction port 7 is preferably 0.5 cm or more and 5 cm or less, and the flow velocity of the suction air flow at the suction port 7 is preferably 5 m / sec or more.
The depth of the slit 8 (floor slit portion 8a and wall slit portion 8b) (distance from the suction port 7 to the chamber 9) is 5 cm or more, and the width dimension of the flange portion 10 provided on both sides of the suction port 7 is 2 cm. As described above, it is preferable that the radius of curvature of the folded portion 11 for making the suction port 7 into a bell mouth shape is 5 cm or less, and the diameter of the chamber 9 (the floor chamber portion 9a and the wall chamber portion 9b) is 5 cm or more.

In the present embodiment, assuming that water enters the capture mechanism 5 from the suction port 7, a water gradient of about 1/100 is provided in the floor chamber portion 9a as shown in FIG. A drain pipe 20 is connected to the lower side (right end side in FIG. 2), and the tip of the drain pipe 20 is connected to a drain pit 22 via a water sealing mechanism 21. Reference numeral 23 is a discharge pipe from the drain pit 22, and 24 is an inspection port that also serves as a lid for the drain pit 22.
In the example shown in the figure, the drainage pit 22 is shaped like a trap bowl, a sealed water reservoir 25 is secured at the bottom, and the tip of the drain pipe 20 is directed downward to be submerged in the sealed water reservoir 25 to form the water seal mechanism 21. Therefore, as shown in FIG. 2, the water level in the trap rises slightly from the surroundings as the trapping mechanism 5 is made to have a negative pressure by the suction blower 6.
Further, in the present embodiment, the floor chamber portion 9a is directly extended to the underwater side (that is, a pipe material such as a vinyl chloride pipe constituting the floor chamber portion 9a is extended to the underwater side as it is) The extension portion is used as the drain pipe 20 as it is, and a filter 26 is provided on the inner side of the distal end portion at a position above the sealed water reservoir 25. The filter 26 captures the insects captured in the floor chamber portion 9a to prevent the insects from flowing into the drain pit 22, and prevents the insects from entering the catch mechanism 5 from the drain pit 22. Cleaning and maintenance inspection can be performed in the drain pit 22, and an inspection port 27 for that purpose is also provided in the upper part of the drain pipe 20.

On the other hand, a duct 30 is connected to the water upper side (the left end side in FIG. 2) of the floor chamber portion 9a, the duct 30 is raised on the floor surface at a desired position, and the suction blower 6 is connected to the tip thereof. Has been. In this embodiment, the floor chamber portion 9a is directly extended to the water side (that is, the pipe material such as a vinyl chloride pipe constituting the floor chamber portion 9a is directly extended to the water side), and the extension portion is left as it is. Used as a duct 30.
A filter 31 is also provided in the middle of the duct 30, and insects captured in the floor chamber portion 9 a are not captured by the filter 31 and are not re-released through the suction blower 6. .
The suction blower 6 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 6 intermittently only in a desired time zone, for example, 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 6 is always operated when the shutter 3 is opened). Of course, if necessary, the suction blower 6 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 of the present embodiment is provided with a cleaning mechanism 40 for supplying chemical liquid such as cleaning water and disinfecting liquid to the capturing mechanism 5 and cleaning it. The cleaning mechanism 40 in the present embodiment is configured to spray cleaning water from the cleaning water tank 41 through the supply pipe 42 to the middle of the duct 30 by the nozzle 43, and the cleaning water is discharged from the duct 30 to the floor chamber portion 9 a and the drain pipe 20. The inner surface is washed down to clean the inner surface. 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 device of the present embodiment configured as described above, when the suction blower 6 is operated, the air near the floor and the bottom of the wall surface is sucked into the suction port 7 by the suction force, and the suction is performed. Insects in the vicinity can be sucked into the suction port 7 by the air flow and captured in the chamber 9 through the slit 8. Therefore, as long as the suction blower 6 is operated, insects cannot pass across the suction port 7 and can prevent intrusion into the building from the doorway 1 inside thereof. It is possible to reliably prevent the invasion of insects that have passed through the corners between the floor and the wall, which was a weak point.
Of course, it is impossible for the captured insects to escape back in the slit 8 until it resists the suction air flow, and since the filters 26 and 31 are provided before and after the chamber 9 respectively, the drainage is performed. It cannot escape to the pit 22 or the suction blower 6 side, and will eventually die in the floor chamber portion 9a.

  In particular, in the insect intrusion prevention apparatus according to the present embodiment, the suction port 7 is processed into a bell mouth shape, so that a suction air flow necessary for sucking insects is formed reliably and sufficiently, and the suction port 7 On both sides, a folded portion 11 is formed by folding the heel portion 10 as a smooth curved surface, so that insects can be prevented from clinging to it, and thereby insects can be sucked more reliably. Yes.

In addition, since the suction port 7 is open to the floor surface and the wall surface, for example, inflow of rainwater or inflow of cleaning water during floor surface cleaning is assumed. In the insect intrusion prevention device of this embodiment, the floor chamber A water gradient is secured in the portion 9a, and a drain pipe 20 is provided on the lower side of the section 9a. Since the drain 9 is connected to the drain pit 22 through the sealing mechanism 21, the water can be drained without any trouble. Cleaning with can also be performed easily.
Moreover, since the cleaning mechanism 40 for supplying cleaning water and chemicals to the capture mechanism 5 for cleaning is provided, the cleaning mechanism 40 performs cleaning operations periodically or as necessary, The inside of the capture mechanism 5 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 of the present embodiment, it is possible to reliably prevent the invasion of insects traveling on the floor surface and the wall surface. 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, floors and walls that were weak points of these conventional devices It is possible to sufficiently prevent the invasion of insects through the wall, particularly the invasion prevention of insects that travel along the corners between the floor and the wall, thereby realizing a complete invasion prevention.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various design changes and applications such as those listed below are possible.
The specific shape, dimensions, and specifications of each part of the insect intrusion prevention device of the present invention are determined in consideration of the type of insects to be captured, their sizes, habits, etc. What is necessary is just to design optimally considering the finishing and design of the floor.
For example, in the above embodiment, the wall chamber portion 9b is installed outside the sleeve wall 4, but if necessary, it may be concealed with an appropriate cover or finishing material, or embedded in the sleeve wall 4 as shown in FIG. May be. Of course, the sleeve wall 4 is not necessarily formed as a concrete structure or the like, and various panels and exterior materials can be used instead of the sleeve wall as long as it can function as a wall portion that can prevent insects from entering. It may be provided as a wall.

  In the above embodiment, the suction port 7 has a bell mouth shape, but it is only necessary to open the suction port 7 on the floor so that a sufficient and preferable suction air flow necessary for sucking insects to be captured can be formed. Yes, as long as the shape and size of the suction port 7 is arbitrary, the shape is not necessarily a bell mouth shape, and the hook portion 10 for forming the folded portion 11 that is easy to slide is not necessarily provided on both sides thereof. .

In the above embodiment, the suction blower 6 is connected to the water upper side of the collection mechanism 5 via the duct 30. However, the suction blower 6 maintains the entire inside of the chamber 9 at a desired negative pressure and is close to the suction port 7. As long as a suction air flow having a desired flow rate and a desired flow rate can be formed, the suction blower 6 may be connected to the lower side of the chamber 9 or an arbitrary position.
Further, in the above embodiment, a water gradient is secured in the floor chamber portion 9a for draining water, and the drain pipe 20 and the drain pit 22 are provided below the water, but there is a concern that water such as rainwater flows into the chamber 9. If there is no need to consider washing with washing water or a chemical solution, that is, if there is no need to consider draining in particular, 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, 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 or chemicals into the duct 30 from the nozzle 43 provided on the water upper side of the floor chamber portion 9a. Alternatively, in addition to this, a cleaning mechanism configured to spray or wash the cleaning water or the chemical solution on the entire capture mechanism 5 including the slit 8, the drain pipe 20, and the drain pit 22 may be considered. 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.

In the embodiment described above, the floor suction port 7a extends over the entire width of the entrance / exit 1 for the main purpose of preventing intrusion from the floor surface over the entire width of the entrance / exit 1 and the lower portion of the sleeve wall 4 (entrance to the floor surface). And the wall suction port 7b is provided at the lower portion of the sleeve wall 4, but the wall suction port 7b is provided so as to cover the entire height of the sleeve wall 4 in order to prevent intrusion from the entire wall surface (in this case, the wall chamber Of course, the portion 9b may be raised to the height of the ceiling surface.
In any case, the insect intrusion prevention device according to the present invention prevents the invasion through the floor and the intrusion through the wall surface (at least the lower part of the wall surface), so it flies and jumps into the entrance / exit. Invasion of insects and insects that travel along other routes needs to be prevented by other means. Therefore, as described above, the insect intrusion prevention device of the present invention is another device such as an air curtain or an air shower. It is realistic to use them together as a supplement, and usually should be so.
However, intrusion from other routes need not be considered at all, and in the case where only intrusion from the floor and wall surface should be considered, it does not preclude the use of the device of the present invention alone. On the contrary, if necessary, the apparatus of the present invention may be provided not only on the floor and wall surfaces but also on the ceiling surface (that is, the suction port 7 is provided without gaps over the entire circumference of the entrance / exit 1). Invasion of insects not only on the surface and wall surface but also on the ceiling surface can be effectively prevented.

In consideration of combinations with other devices such as air curtains and air showers, the device of the present invention is preferably installed outside the entrance and exit as in the above embodiment, but instead installed inside the entrance and exit. It is also conceivable to install double on both the outside and inside of the entrance / exit. In that case, even if insects can pass through the doorway, they are caught immediately after that and cannot 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.
