It is preferable that a blowout side chamber that extends and communicates with the entire length of the blower port is disposed, and the blower port and the blower blowout port of the blower communicate with each other through the blowout side chamber. .
Thereby, when the blower is operated, the inside of the blowout side chamber becomes a positive pressure, and air is blown out from the blower opening extending over the entire width of the inlet / outlet by the positive pressure. At this time, the wind pressure of the air blown out from the air blowing port becomes substantially uniform over the entire length of the air blowing port.

Further, in the insect invasion preventing device according to the present invention, the air inlet extends over the entire width of the inlet / outlet, and below the floor under the air inlet, along the length direction of the air inlet. It is preferable that an intake side chamber that extends and communicates with the entire length of the intake port is disposed, and the intake port and the suction port of the blower communicate with each other through the intake side chamber. .
Thereby, when the blower is operated, the inside of the intake side chamber becomes negative pressure, and the air on the floor surface is sucked from the intake port extending over the entire width of the inlet / outlet by this negative pressure. At this time, the wind pressure (suction force) of the air sucked from the intake port becomes substantially uniform over the entire length of the intake port.

  According to the insect invasion preventing apparatus according to the present invention, it is possible to prevent the invasion of walking insects by air blown out from the air blowing port or suction from the air intake port. Moreover, since the air inlet and the air outlet are formed on the floor surface and the air blower is disposed under the floor, it is possible to improve the fit near the entrance / exit.

In addition, the air inlet 2 extends in a band shape over the entire width of the entrance / exit 10, that is, from the inner surface of one wall 13A to the inner surface of the other wall 13B.

  If it demonstrates in detail, the above-mentioned inlet 2 and the ventilation port 3 consist of the flat and horizontally long cylindrical bodies 23 and 33 standingly arranged along the perpendicular direction. These cylindrical bodies 23 and 33 are members made of metal such as stainless steel or aluminum or resin, and are buried under the floor, respectively, and each upper end opening is opened from the floor surface toward the passage 11. Further, flange portions 20 and 30 (folded portions) projecting outward (target region X side or external region Y side) are formed at the longitudinal edges of the upper ends of the cylindrical bodies 23 and 33. Each is provided. In other words, the upper end openings of the cylindrical bodies 23 and 33 are folded back on both sides to form a bell mouth shape in sectional view. Moreover, the adjustment piece 31 for adjusting the slit opening width and injecting the injection airflow A toward the external region Y side is attached to the air outlet 3. The upper surfaces of the flange portions 20 and 30 and the adjustment piece 31 are preferably formed flush with the floor surface so as not to be stepped, and sufficient to prevent insects from clinging to the floor surface. It is preferable to finish it smoothly.

  The blowout side chamber 6 is a blower passage that sends air blown from the blowout port 41 of the blower 4 to the blower port 3. The blowout port 41 and the blower port 3 are communicated with each other through the blowout side chamber 6. Yes. The blow-out side chamber 6 is buried under the floor directly below the blower port 3 and is disposed at a position outside (external region Y side) from the blower 4 (floor pit 14). In addition, the blowout side chamber 6 extends along the length direction of the air blowing port 3 and extends longer than at least the air blowing port 3, and is communicated with the air blowing port 3 over the entire length. Yes.

  The intake side chamber 5 is an intake passage that sends the air sucked from the intake port 2 to the intake port 40 of the blower 4. The intake port 40 and the intake port 2 are communicated with each other through the intake side chamber 5. Yes. The intake side chamber 5 is buried under the floor directly below the intake port 2 and is disposed at a position on the inner side (target region X side) than the blower 4 (underfloor pit 14). The intake side chamber 5 extends along the length direction of the intake port 2 and extends at least longer than the intake port 2, and communicates with the intake port 2 over the entire length. Yes.

  More specifically, the intake side chamber 5 and the blowout side chamber 6 described above are formed of a cylindrical tubular body extending along the width direction of the passage 11 (the length direction of the intake port 2 and the blower port 3). For example, it is a member made of a vinyl chloride pipe. The intake side chamber 5 and the blowout side chamber 6 have upper portions cut out in a slit shape along the length direction, and lower portions of the cylindrical bodies 23 and 33 described above are inserted into the cut portions. The members 23 and 33 are airtightly connected. Further, a joint pipe that is orthogonal to the intake side chamber 5 and the blowout side chamber 6 and communicates with the intake side chamber 5 and the blowout side chamber 6 is provided at an intermediate portion in the length direction of the intake side chamber 5 and the blowout side chamber 6. 50 and 60 are projected. The front ends of these joint pipes 50 and 60 are protruded toward the inside of the underground pit 14, and the front ends of the joint pipes 50 of the intake side chamber 5 are connected to the suction port 40 of the blower 4. 6 is connected to the outlet 41 of the blower 4. Further, a filter 51 that removes unnecessary substances such as dust, dust, and insects sucked from the intake port 2 is installed inside the joint pipe 50 of the intake side chamber 5.

  It should be noted that the dimensions and shapes of the intake port 2, the blower port 3, the intake side chamber 5, and the blowout side chamber 6, the material, or the wind speed of the intake air at the intake port 2 and the blown air (injection airflow A) Each specification such as air volume should be optimally set in consideration of the type and size of insects that are supposed to be intrusion prevention targets, but when assuming rubber bugs, rotifers, black ants, German cockroaches, black cockroaches, etc. If a suitable example is given, the slit width D1 of the ventilation port 3 will be about 5-50 mm, and the height H of the ventilation port 3 (dimension from the upper end opening of the ventilation port 3 to the upper end of the blowing side chamber 6) will be about 50-300 mm. It is good to do.

  Moreover, it is preferable that the slit opening width D2 (width of the injection port 32) of the blower port 3 is about 5 to 30 mm, and the flow velocity of the jet air flow A from the blower port 3 is 2 m / sec or more. As shown in FIG. 2, the jet direction of the jet air flow A is adjusted in a range (injection direction adjustment range B) from a direction parallel to the floor surface (usually horizontal direction) to a direction perpendicular to the floor surface (usually vertical direction). It should be possible. Such adjustment can be performed freely and easily by setting the opening shapes of the adjustment piece 31 and the air blowing port 3.

  Next, the operation of the insect intrusion prevention device 1 having the above-described configuration will be described.

  When the blower 4 described above is operated by operating a control device (not shown), air is sucked in from the suction port 40 of the blower 4 and air is blown out from the blowout port 41, and air is sucked in from the suction port 2 and the blower port. Air blows from 3 As a result, walking insects that try to enter the target region X along the floor surface of the passage 11 are eliminated by air blown from the air blowing port 3 or suction from the air intake port 2. More specifically, since the air blowing port 3 is disposed on the external region Y side of the air intake port 2 described above, first, the air blown from the air blowing port 3 travels along the floor surface of the passage 11 to the target region X. Many of the walking insects that try to invade are eliminated by being blown away or not being close. Even if some walking insects try to enter the target region X through the air blowing port 3, they are sucked into the air intake port 2 and reliably excluded when passing through the air intake port 2.

  Further, when a person or a vehicle enters the target area X from the external area Y through the entrance 10, there is a possibility that the clean environment of the target area X is contaminated if mud or dust adheres to shoes or tires. However, dust and mud adhering to these shoes and tires are removed by air blown out from the air blowing port 3 or suction from the air intake port 2. More specifically, since the air blowing port 3 is disposed on the outer region Y side of the air intake port 2 described above, first, a lot of dust, mud, etc. attached to shoes and tires by the air blown out from the air blowing port 3. Blowed away. Even if dust, mud, or the like cannot be completely removed, the dust is sucked into the intake port 2 and reliably removed when passing through the intake port 2.

  In addition, since the intake port 2 and the blower port 3 described above extend in a band shape over the entire width of the entrance 10, when the walking insects enter the target region X along the floor surface, When the vehicle enters the target area X, it always passes through the air inlet 2 and the air outlet 3. For this reason, the walking type insects that try to enter the target region X through the floor surface of the passage 11 are surely removed, and dust, mud, and the like attached to shoes and tires are surely removed.

  In addition, the intake port 2 and the suction port 40 of the blower 4 are communicated with each other via an intake side chamber 5 extending along the length direction of the intake port 2, and along the length direction of the blower port 3. Since the blower port 3 and the blower port 41 of the blower 4 are in communication with each other through the extended blower side chamber 6, when the blower 4 is operated, the intake side chamber 5 becomes negative pressure and the blowout side chamber 6. The inside becomes a positive pressure, air on the floor surface is sucked from the intake port 2 by the negative pressure in the intake side chamber 5, and air is blown out from the blower port 3 by the positive pressure in the blowout side chamber 6. Thereby, the wind pressure (suction force) of the air sucked from the intake port 2 and the wind pressure of the air blown from the blower port 3 become substantially uniform over the entire length.

  In addition, the above-described blower 4 can be controlled by a desired timer control or program control set in advance in addition to any manual operation. For example, it is a control that intermittently operates only in a desired time zone, or automatically operates in conjunction with the opening / closing operation of the shutter 12 (that is, the blower 4 operates when the shutter 12 is opened). Also good. Of course, if necessary, the blower 4 can be operated continuously at all times, and when other insect intrusion prevention devices are arranged side by side, it can be controlled to operate in conjunction with them. Conceivable.

According to the insect invasion preventing apparatus 1 described above, walking insects can be eliminated by air blown from the air blowing port 3 or suction from the air intake port 2, and the walking type insects can be prevented from entering the target region X. can do.
Further, dust adhering to a person's shoes or a car tire passing through the passage 11 can be removed by air blown out from the air blowing port 3 or suction from the air intake port 2.
Furthermore, since the air inlet 2 and the air outlet 3 are formed on the floor and the air blower 4 is disposed under the floor, and no duct or the like is disposed in the passage 11, it is possible to improve the fit near the entrance 10. it can.

  In addition, in the insect intrusion prevention device 1 described above, a lot of dust and the like adhering to walking type insects and shoes is blown out by blowing air from the air blowing port 3, and the walking type insects pass through the air blowing port 3 temporarily. In this case, when dust or the like of shoes or the like does not completely fall out, they are sucked by the air inlet 2, so that insects and dust sucked into the air inlet 2 become small. For this reason, the problem that the intake port 2 is clogged with insects or dust or the inside of the intake side chamber 5 is less likely to occur, and the filter 51 of the intake side chamber 5 is also difficult to get dirty. Therefore, it is possible to reduce the maintenance work of cleaning the intake port 2 and the intake side chamber 5 and cleaning and replacing the filter 51.

  Further, in the insect invasion preventing device 1 described above, the blowout port 41 and the blower port 3 of the blower 4 are communicated with each other via the blowout side chamber 6 extending along the blower port 3, and blown out from the blower port 3. Since the wind pressure of the air is substantially uniform over the entire length of the air blowing port 3 (the entire width of the entrance / exit 10), there are no places where the wind pressure is weak, and it is possible to reliably eliminate walking insects that are about to enter the target region X. In addition, dust, mud and the like attached to shoes and tires can be reliably removed.

  Further, in the insect invasion preventing device 1 described above, the suction port 40 and the suction port 2 of the blower 4 are communicated with each other via the suction side chamber 5 extending along the suction port 2. Since the suction force is substantially uniform over the entire length of the air inlet 2 (the entire width of the inlet / outlet port 10), there are no places where the suction force is weak, and it is possible to reliably eliminate the walking insects that try to enter the target region X. In addition, dust, mud and the like attached to shoes and tires can be reliably removed.
