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 suction type device shown in Patent Document 3 has been proposed, and by using it together with the air curtain and air shower as described above, the invasion of insects traveling on the floor surface can be almost surely prevented. it can.
However, such a suction-type device sucks not only insects to be captured but also foreign matters such as dust and fallen leaves. Therefore, frequent maintenance cleaning and maintenance are indispensable in order to maintain the capturing effect.

  In view of the above circumstances, an object of the present invention is to provide an effective and appropriate device capable of reliably preventing insects entering the floor.

  The invention described in claim 1 is an insect intrusion prevention device for preventing insects from entering the compartment to be kept clean through the floor surface, and is pressurized and supplied from the blower to the chamber. An injection mechanism configured to inject air onto the floor surface through the slit is installed across the entire width of the inlet / outlet below the floor outside the inlet / outlet into the compartment, and the jet air flow is directed to the outside of the inlet / outlet at the upper end of the slit An injection port for jetting is provided, and the injection port is opened on the floor surface.

  The invention described in claim 2 is the insect invasion preventing device according to claim 1, wherein a water gradient is provided in the injection mechanism, and a water drain pipe is connected to the underwater side of the spray mechanism, and the water drain pipe is provided. It is characterized by connecting the front-end | tip part of this to a drainage pit through a sealing mechanism.

  The invention described in claim 3 is the insect invasion prevention device of the invention described in claim 1 or 2, wherein a cleaning mechanism is provided for cleaning by supplying a chemical solution such as cleaning water or disinfecting solution to the spray mechanism. It is characterized by comprising.

  According to the insect invasion preventing apparatus of the present invention, insects approaching the entrance / exit along the floor surface can be blown off by the jet air flow from the injection port or prevented from approaching the entrance / exit, thereby preventing the insect from entering. It is possible to prevent the kind from reaching the doorway and reliably prevent the intrusion from there. Therefore, when the device of the present invention is used in combination with other insect invasion prevention devices such as air curtains and air showers, it is sufficient to prevent the invasion of insects traveling on the floor, which was a weak point of these conventional devices. It can be complemented and complete prevention of intrusion can be realized.

In particular, by providing a water gradient in the injection mechanism and providing a drain pipe and drainage pit on the lower side of the injection mechanism, even if water enters the injection mechanism from the injection port that is open on the floor, it will hinder draining from there. It can be carried out without any problems, and there is no sanitary problem by connecting the drain pipe to the drain pit via a sealing mechanism.
In addition, by providing a cleaning mechanism for supplying a chemical solution such as cleaning water or a disinfecting solution to the injection mechanism, even if insects enter the injection mechanism, it can always be kept clean.

  An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the insect intrusion prevention apparatus according to the present embodiment is installed outside the entrance 1 of a building (the inside of which is a clean compartment to prevent insects from entering). Insects trying to invade along the floor 2 are blown outwardly before the doorway 1 to reliably prevent the invasion.

  In FIG. 1, reference numeral 3 is a shutter provided at the entrance 1, 4 is an outer wall, 5 is a pillar, and 6 is a sleeve wall provided outside the pillar 5. The main part is composed of an injection mechanism 11 embedded in the floor 2 outside the shutter 3 across the ends of the sleeve walls 6 and a blower 12 (see FIG. 2) connected to the injection mechanism 11.

As shown in FIG. 3, the injection mechanism 11 includes a slit 14 whose upper end is opened as an injection port 13 in the floor surface 2 and a chamber 15 integrally connected to the lower portion thereof, as shown in FIG. .
The slit 14 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 the upper end of the slit 14 is folded back on both sides to make a bell mouth shape. Although functioning as the injection port 13, the adjustment piece 14a for adjusting the width | variety and injecting the injection airflow 18 toward the building exterior side is attached to the injection port 13. As shown in FIG. It should be noted that it is preferable to finish the surface of the folded-back portion and the adjustment piece 14a in which the injection port 13 is formed in a bell mouth shape sufficiently smooth so that insects cannot cling thereto.
The chamber 15 is made of, for example, a pipe material such as a vinyl chloride pipe, and is integrally connected so as to be kept airtight in a state where the upper portion thereof is cut into a slit shape and the lower portion of the slit 14 is slightly inserted therein. Yes.

The specifications such as the size and shape of the slit 14 and the chamber 15 in the injection mechanism 11, the material, the wind speed and the air volume of the injection air flow 18 to be ensured at the injection port 13, etc. It may be optimally set in consideration of the type and size thereof. However, if a suitable example is assumed assuming a rubber dipper, a common bug, a black cockroach, a black cockroach, the width of the slit 14 is about 5 to 50 mm. The height of the slit 14 (the distance between the injection port 13 and the chamber 15) is preferably about 50 to 300 mm.
Further, the width of the injection port 13 is preferably about 5 to 30 mm, and the flow velocity of the injection air flow 18 at the injection port 13 is preferably 2 m / sec or more, and the injection direction from the injection port 13 is the floor surface as shown in FIG. It is preferable that adjustment is possible in a range from a direction parallel to 2 (usually horizontal) to a direction perpendicular to floor 2 (usually vertical). Such adjustment can be performed freely and easily by setting the opening shape of the upper end of the adjustment piece 14 a and the slit 14.

As shown in FIG. 1, the injection mechanism 11 is embedded in the floor surface 2 outside the entrance 1 over the entire length between the sleeve walls 6 without a gap, but water enters the injection mechanism 11 from the injection port 13. Assuming that, the injection mechanism 11 is provided with a water gradient of about 1/100 as shown in FIG. 2, and a drain pipe 20 is connected to the water side (the right end side in FIG. 2). The distal end portion of the drain pipe 20 is connected to the drain pit 22 via the 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 is slightly lower than the surroundings by the amount of positive pressure in the injection mechanism 11 by the blower 12.
Further, in the present embodiment, the chamber 15 is directly extended to the underwater side (that is, a pipe material such as a vinyl chloride pipe constituting the chamber 15 is extended to the underwater side as it is), and the extension portion is left as it is. A drain pipe 20 is provided, and a filter 26 is provided inside the tip of the drain pipe 20 at a position above the sealed water reservoir 25. The filter 26 prevents insects from entering the injection mechanism 15 from the drainage pit 22, and catches insects when they enter the chamber 15 from the injection port 13 and escapes to the drainage pit 22. Therefore, the filter 26 can be cleaned and maintained in the drain pit 22, and an inspection port 27 for this 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 injection mechanism 11, the duct 30 is raised on the floor surface at a desired position, and the blower 12 is connected to the tip thereof. Yes. In this embodiment, the chamber 15 is directly extended to the water side (that is, a pipe material such as a vinyl chloride pipe constituting the chamber 15 is directly extended to the water side), and the extended portion is used as the duct 30 as it is. Has been.
A filter 31 is also provided in the middle of the duct 30 so that insects that have entered the chamber 15 are captured by the filter 31 and cannot escape through the blower 12.
The 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 blower 12 intermittently only in a desired time zone, for example, by a preset desired timer control or program control. Control that automatically operates in conjunction with the opening / closing operation of the shutter 3 (that is, the blower 12 is always operated when the shutter 3 is opened) is possible. Of course, if necessary, the blower 12 can be operated continuously at all times, and when other insect intrusion prevention devices are arranged in parallel, the blower 12 can be controlled to operate in conjunction therewith. Conceivable.

  Furthermore, the insect intrusion prevention apparatus of the present embodiment is provided with a cleaning mechanism 40 for supplying a cleaning solution, a disinfecting solution, and other chemicals to the spray mechanism 11 to clean 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 to be 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 device of the present embodiment configured as described above, when the blower 12 is operated, the blower 12 passes the chamber 15 and the slit 14 through the injection port 13 as the upper opening to the vicinity of the floor surface 2. The jet air stream 18 is jetted, so that insects in the vicinity of the jet port 13 can be blown away by the jet air stream 18 in the direction opposite to the entrance / exit 1. Therefore, as long as the blower 12 is operated, insects cannot enter the inside of the injection port 13 beyond the injection port 13, thereby reliably preventing the entry from the doorway 1.
If insects enter the injection mechanism 11 against the injection air flow 18, the filters 26 and 31 are provided before and after the chamber 15, respectively, so that the drain pit 22 and the blower 12 side are provided. They cannot escape and eventually die in the chamber 15.

In addition, since the injection port 13 is open to the floor surface 2, it is assumed that, for example, inflow of rainwater or washing water for floor cleaning flows into the injection mechanism 11, but the insects of this embodiment In the intrusion prevention device, a water gradient is secured in the chamber 15 and a water drain pipe 20 is provided on the lower side of the chamber 15 and connected to the drain pit 22 via the water sealing mechanism 21, so that water can be drained without any trouble. In addition, cleaning by water washing can be easily performed.
In addition, since the cleaning mechanism 40 for supplying cleaning water and chemicals to the injection mechanism 11 for cleaning is provided, the cleaning mechanism 40 can perform cleaning operations periodically or as needed, The inside of the injection 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 of the present embodiment, it is possible to reliably prevent the invasion of insects trying to invade from the entrance / exit 1 through the floor surface 2. It is a weak point of these conventional devices by installing them outside the doorway 1 in combination with other insect intrusion prevention devices such as conventional air curtains and air showers as shown in Patent Document 1 and Patent Document 2. Therefore, it is possible to sufficiently prevent the invasion of insects through the floor 2 and to achieve the complete prevention of invasion.
In addition, unlike the suction-type device shown in Patent Document 3, foreign matter other than insects is not sucked in. Therefore, frequent maintenance is required and the intrusion prevention effect is reduced. Therefore, it is advantageous in terms of maintainability and reliability as compared with the suction type.

  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 according to the present invention take into account the type, size, and habits of insects that are to be prevented from entering, and the entrance / exit where this should be installed. What is necessary is just to design optimally considering the size and the finishing and design of the floor.
For example, it is preferable that the adjustment piece 14a is attached to the upper opening of the slit 14 serving as the injection port 13 as in the above embodiment so that the width and the injection direction of the injection port 13 can be adjusted. Not a thing.

  In the above embodiment, a water gradient is secured in the injection mechanism 11 for draining water, and the drain pipe 20 and the drain pit 22 are provided on the lower side of the water. However, there is absolutely no concern that water such as rainwater will flow into the injection mechanism 11. 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 are provided before and after the injection mechanism 11, and maintenance is performed in the drainage pit 22 or by disassembling the duct 30, but there is no concern that insects may enter. For example, the configuration is not necessarily required, and the necessity of the filters 26 and 31, the installation position, the configuration for maintenance, and the like can be appropriately changed. On the other hand, when it is assumed that insects frequently enter, a trap mechanism such as various insect collectors is provided instead of a simple filter, or the captured insects are killed. It does not prevent the addition of a mechanism for making it happen.

  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 side of the injection mechanism 11, but instead, Alternatively, in addition to the above, it is conceivable that the cleaning mechanism is configured to spray or wash the cleaning water or the chemical solution on the entire injection mechanism 11 including the slit 14 and also on the drain pipe 20 and the drain pit 22. 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.

The insect invasion preventing device of the present invention is intended to prevent the invasion of insects that attempt to invade through the floor surface, so that insects that fly and jump into the entrance and other routes It is necessary to prevent the invasion of insects traveling along the path by other means. Therefore, as described above, the insect intrusion prevention apparatus according to the present invention complements other apparatuses such as an air curtain and an air shower with them. It is realistic to use it together 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 to inject the air flow from the entire periphery of the entrance / exit to the outside. Invasion of insects not only on the surface but also on the wall surface and ceiling surface can be effectively prevented.

  In addition, the apparatus of the present invention is not only installed at the entrance to the building from the outside, but in the case where the interior of the building is partitioned to provide an area to be kept clean such as a clean room, for example, Needless to say, it can also be provided in the same way with respect to the entrance to the provided compartment.

It is a plane sectional view showing the state where the insect invasion prevention device which is one embodiment of the present invention was installed outside the doorway. FIG. 2 is an elevational sectional view (a view taken along line II-II in FIG. 1). FIG. 3 is an enlarged cross-sectional view of the injection mechanism (a view taken along line III-III in FIG. 2).
