    By the way, in the building provided with the windbreak room as described above, a door is provided at an entrance between the entrance room and the windbreak room so that the entrance can be closed.

    However, normally, even when the door is closed, a slight gap is formed between the door and the frame for receiving the door. Therefore, by closing the door, it is possible to prevent the outdoor wind from blowing into the windbreak room and the entrance room, but insects that have entered the windbreak room when the door is opened There was a risk of entering the entrance chamber through a slight gap between the door and the frame.

    The present invention has been made in view of such a point, and an object of the present invention is to more reliably prevent the invasion of insects in a building insect control system that prevents the invasion of insects from the outside into the entrance room of the building. is there.

    1st invention has the entrance room (13) used as the entrance / exit space of a building, and the wind chamber (11) provided in the outdoor side of this entrance room (13), and the said entrance room (13 ) An insect repellent system for a building that prevents the invasion of insects into the first door (16) on the outdoor side of the windbreak room (11) and the second door on the entrance room (13) side ( In the state where both of 17) are closed, each chamber pressure is adjusted so that the chamber pressure on the entrance chamber (13) side of the second door (17) is higher than the chamber pressure of the windbreak chamber (11). A chamber pressure adjusting device (20) for adjusting is provided.

    In the first invention, the chamber pressure adjusting device (20) is configured such that the first door (16) and the second door (17) are closed and the windbreak chamber (11) is closed. The chamber pressure of each chamber is adjusted so that the chamber pressure on the entrance chamber (13) side of the door (17) is higher than the chamber pressure of the wind vent chamber (11). Thus, when the two doors of the windbreak chamber (11) are closed, the entrance chamber (13) is formed in the gap between the second door (17) and the frame due to the difference in the chamber pressure on both sides of the second door (17). ) Air flows from the side toward the windbreak chamber (11). Therefore, even if insects invade the windbreak chamber (11) from the outside when the first door (16) is opened, the bugs in the windbreak chamber (11) remain in the gap between the second door (17) and the frame. The air flow blows into the windbreak chamber (11) from scratch, so that the gap cannot be penetrated to enter the entrance chamber (13).

    According to a second aspect, in the first aspect, the floor surface of the windbreak chamber (11) has a stepped portion (30 where the second door (17) side is higher than the first door (16) side. )have.

    In the second invention, when the ground worm (X) crawling on the ground enters the windbreak chamber (11) when the first door (16) is opened, the stepped portion (30) on the floor surface becomes the barrier. Thus, the earthworm (X) cannot enter the second door (17) side from the stepped portion (30). That is, even if the earthworm (X) enters the building, it is stopped in the windbreak room (11).

    According to a third aspect, in the second aspect, the stepped portion (30) has an upper floor surface so that insects scooping up the kick may not reach the upper floor surface (32) of the stepped portion (30). A return member (33) that prevents entry into (32) is provided.

    In the third invention, even if there is an insect that can scoop up the stepped portion (30) in the earthworm (X) that has entered the windbreak chamber (11), the return member (33) As a barrier, insects cannot reach the upper floor (32) of the step (30).

According to a first aspect of the present invention, in the above configuration , the chamber pressure adjusting device (20) includes a first door (16) on the outdoor side of the windbreak chamber (11) and a second door on the entrance chamber (13) side. In a state where both the doors (17) are closed, the chamber pressure of the windbreak chamber (11) is adjusted to be higher than the outdoor atmospheric pressure.

In the first invention, the chamber pressure adjusting device (20) is arranged in a state where the first door (16) and the second door (17) are closed and the wind chamber (11) is closed. The chamber pressure in the windbreak chamber (11) is adjusted so that the chamber pressure in the chamber (11) is higher than the atmospheric pressure outside. Thereby, when the two doors of the windbreak chamber (11) are closed, the outdoor atmospheric pressure and the windbreak chamber (with the first door (16) sandwiched between the first door (16) and the frame are closed. Due to the pressure difference from the room pressure of 11), air flows from the windbreak room (11) toward the outside. For this reason, outdoor insects penetrate the clearance chamber (11) through the clearance between the first door (16) and the frame through the clearance between the first door (16) and the frame. become unable.

Is provided with an inner wind vent chamber (12) provided with a third door (18) between the entrance chamber (13) and the chamber pressure adjusting device (20). In the state where both the second door (17) on the outdoor side of the chamber (12) and the third door (18) on the entrance chamber (13) side are closed, the inner wind vent (12) The chamber pressure is adjusted to be higher than the chamber pressure of the windbreak chamber (11) and lower than the chamber pressure of the entrance chamber (13).

In the first aspect of the invention, an inner wind vent chamber (12) is further provided between the wind vent chamber (11) and the entrance chamber (13). Therefore, when the first door (16) opens, even if an insect enters the windbreak chamber (11), it must exceed two doors to reach the entrance chamber (13). Insect entry into the entrance room (13) becomes very difficult.

In the first invention, the chamber pressure adjusting device (20) is configured such that the second door (17) and the third door (18) are closed and the inner wind vent chamber (12) is closed. The chamber pressure in the inner wind chamber (12) is adjusted to be higher than the outdoor wind chamber (11) and lower than the chamber pressure in the entrance chamber (13). Therefore, when the two doors of the inner wind vent chamber (12) are closed, the gap between the second door (17) and the frame is caused by the difference in the chamber pressure between the wind vent chamber (11) and the inner wind vent chamber (12). , Air flows from the inner wind vent chamber (12) to the wind vent chamber (11), and this air flow prevents insects that have entered the wind vent chamber (11) from entering the inner wind vent chamber (12). Similarly, when the two doors of the inner wind chamber (12) are closed, the third door (18) and the frame are separated by the difference in the room pressure between the inner wind chamber (12) and the entrance chamber (13). In this gap, air flows from the entrance chamber (13) to the inner wind vent chamber (12), and this air flow prevents insects that have entered the inner wind vent chamber (12) from entering the entrance chamber (13).

According to a first aspect of the present invention, in the above configuration , the first door (16) and the second door (17) are not opened at the same time. When one door is opened, the other door is not opened. The second door (17) and the third door (18) are configured to be locked so that the other door is not opened when one door is opened so that the other door is not opened simultaneously. It is comprised so that.

Each chamber pressure is adjusted to be higher than the chamber pressure of the windbreak chamber (11). Therefore, when the two doors of the windbreak chamber (11) are closed, the gap between the second door (17) on the entrance chamber (13) side of the windbreak chamber (11) Air flows from the entrance chamber (13) to the windbreak chamber (11) due to the difference in the chamber pressure on both sides. Thus, even if insects enter the windbreak chamber (11) from the outside, the insects in the windbreak chamber (11) blow to the windbreak chamber (11) from the gap between the second door (17) and the frame. Due to the air flow, the gap cannot be penetrated into the entrance chamber (13). Therefore, according to the first invention, insects can be reliably prevented from entering the entrance chamber (13) from the outside.

    Moreover, according to 2nd invention, the level | step-difference part (30) from which the 2nd door (17) side is higher than the 1st door (16) side is formed in the floor surface of a windbreak chamber (11). Therefore, when the earthworm (X) crawling on the ground invades the windbreak chamber (11), the step (30) on the floor becomes a barrier, and the insect is second from the step (30). Cannot enter the door (17) side. That is, even if the earthworm (X) enters the building, it is stopped in the windbreak room (11). Therefore, according to the second invention, it is possible to more reliably prevent insects from entering the entrance room (13) from the outside.

    Further, according to the third aspect of the invention, since the return member (33) is provided in the step portion (30) of the floor surface of the windbreak chamber (11), the earthworm (X) that has entered the windbreak chamber (11) Even if there is an insect that can scoop up the step (30), the return member (33) acts as a barrier, and the insect reaches the upper floor (32) of the step (30). become unable. Therefore, according to the third invention, it is possible to more reliably prevent insects from entering the entrance chamber (13) from the outside.

Further, according to the first invention, when the two doors of the windbreak chamber (11) are closed, the chamber pressure adjusting device (20) is configured such that the chamber pressure of the windbreak chamber (11) is higher than the outdoor atmospheric pressure. The chamber pressure of the windbreak chamber (11) is adjusted so as to increase. Therefore, in the clearance between the first door (16) on the outdoor side of the windbreak chamber (11), the pressure difference between the atmospheric pressure outside the first door (16) and the chamber pressure of the windbreak chamber (11). As a result, air flows from the windbreak chamber (11) toward the outside. As a result, the insects in the outdoors scavenge from the windbreak chamber (11) through the gap between the first door (16) and the frame to the windbreak room (11). It becomes impossible to invade. Therefore, according to the first invention, insects can be more reliably prevented from entering the entrance chamber (13) from the outside.

Moreover, according to 1st invention, it was decided to further provide an inner side wind chamber (12) between the wind chamber (11) and the entrance chamber (13). Therefore, when the first door (16) opens, even if an insect enters the windbreak chamber (11), it must exceed two doors to reach the entrance chamber (13). Therefore, it is possible to more reliably prevent insects from entering the entrance chamber (13). In particular, since a further wind vent room (inner wind vent chamber) was provided on the back side of the wind vent chamber (11) where the step (30) that hinders the invasion of earthworms (X) on the floor surface, It is possible to effectively prevent worms (X) from entering the entrance chamber (13).

According to the first invention, the chamber pressure adjusting device (20) is configured such that when the two doors of the inner wind vent chamber (12) are closed, the chamber pressure of the inner wind vent chamber (12) The configuration is such that it is adjusted to be higher than the windbreak chamber (11) and lower than the chamber pressure of the entrance chamber (13). Therefore, when the two doors of the inner wind vent chamber (12) are closed, the gap between the second door (17) and the frame is caused by the difference in the chamber pressure between the wind vent chamber (11) and the inner wind vent chamber (12). , Air flows from the inner wind vent chamber (12) to the wind vent chamber (11), and this air flow prevents insects that have entered the wind vent chamber (11) from entering the inner wind vent chamber (12). Similarly, when the two doors of the inner wind chamber (12) are closed, the third door (18) and the frame are separated by the difference in the room pressure between the inner wind chamber (12) and the entrance chamber (13). In this gap, air flows from the entrance chamber (13) to the inner wind vent chamber (12), and this air flow prevents insects that have entered the inner wind vent chamber (12) from entering the entrance chamber (13). Therefore, according to the first invention, insects can be more reliably prevented from entering the entrance chamber (13) from the outside.

According to the first invention, the first to third doors (16 to 18) are configured to be locked so that the other door is not opened when one of the adjacent doors is opened. With this configuration, the two doors provided at the front and rear in each windbreak chamber (11, 12) do not open simultaneously. Therefore, there is no communication between the outdoor windbreak chamber (12) and the windbreak chamber (11), and the windbreak chamber (11) and the entrance chamber (13) connect the inner windbreak chamber (12). There is no communication through. Therefore, according to the first invention, insects can be more reliably prevented from entering the entrance chamber (13) from the outside. Fly insects such as flies may invade from the windbreak chamber (11) into the entrance chamber (13) at once when the first to third doors (16-18) are opened simultaneously. Therefore, the first to third door (16-18) of the first invention is not to be opened all at the same time, in particular, among the insects attempting to break into the building, flying insect entrance chamber, such as flies Effective in preventing entry into (13).

In the present embodiment, as the external light (50), low insect attracting illumination in which light in the ultraviolet region (wavelength of 400 nm or less) that is likely to react with insects is reduced. Insects tend to collect in the lighting equipment that emits light at night, but using such outdoor lights (50) makes it difficult for insects to collect near the entrance door (16).

    In addition, the outer wall of the first windbreak room (11) where the entrance door (16) and the entrance door (16) are provided for the same purpose as using the low worm lighting as the outside light (50) near the entrance door (16) If at least a part of the glass is made of a material that leaks light from the inside, such as glass, an ultraviolet cut film that does not transmit light in the ultraviolet region (wavelength 400 nm or less) is pasted on the glass surface. It is preferable to attach. This makes it difficult for insects to gather near the entrance door (16) even if the light in the building leaks outside at night.

-Operation and action-
Next, the operation and action of the insect control system (10) will be described.

    A chamber pressure adjusting device (20) adjusts the chamber pressures of the first wind chamber (11), the second wind chamber (12), and the entrance chamber (13). Specifically, the air supply fan (23b) and the exhaust fan (24) of the outside air processor (23) are operated, and the controller (28) adjusts the opening degree of the first to third exhaust dampers (27a to 27c). Adjust and adjust all three doors (entrance door (16), outer inner door (17), inner inner door (18)) and the pressure in the first wind chamber (11) is outdoor. 10 Pa higher than the atmospheric pressure of the first wind vent chamber (12), 10 Pa higher than the first wind vent chamber (11), and the pressure in the entrance chamber (13) is the second wind vent. Each chamber pressure is adjusted to be 10 Pa higher than the chamber pressure of the chamber (12).

    As a result, air flows from the entrance chamber (13) to the outside in the gaps between the entrance door (16), the outer inner door (17), and the inner inner door (18) and the frame for receiving them. . Specifically, air flows outward from the first wind chamber (11) in the gap of the entrance door (16), and from the second wind chamber (12) in the gap of the outer inner door (17). Air flows toward the first wind chamber (11), and in the gap between the inner inner doors (18), air flows from the entrance chamber (13) toward the second wind chamber (12). In this way, an air flow with a wind speed of about 4 m / s is formed in the gaps between the doors. Therefore, insects on the outdoor side of each door cannot penetrate into the room on the entrance chamber (13) side by scavenging through the gap due to the air flow blown from the gap between each door and the frame. That is, outdoor insects cannot enter the entrance room (13) through the gaps between the doors.

    In this state, when a person approaches the entrance door (16) to enter the building, the human sensor detects the approach of the person and sends a signal to the air curtain device (40). (40) forms an air curtain. As people enter the building, insects attached to clothes and shoes are swept away as they pass through the air curtain. Further, when the entrance door (16) is opened in order for a person to enter the first wind vent room (11), the air curtain serves as a barrier to prevent the entry of flying insects. At this time, insects attached to the front door (16) are also swept away by the air curtain.

    When the person enters the first wind chamber (11), the outer inner door (17) is locked by the interlock control so that it cannot be opened unless the entrance door (16) is closed. Therefore, since the entrance door (16) is open, even if a flying insect enters the first windbreak chamber (11), the outer inner door (17) is closed, so the flying insect Is not put into the second wind chamber (12), but is stopped together with the person in the first wind chamber (11).

    On the other hand, a step portion (30) is provided in the first windbreak chamber (11). Here, the person takes off his shoes and changes to his upper ones. As a result, even if the ground worm (X) intrudes into the first windbreak chamber (11) together with the shoes, by removing the shoes on the floor (31) below the step (30) The earthworm (X) is also stopped by the lower floor (31). Further, since the stepped portion (30) is provided with the return member (33), the earthworm (X) that has entered the first windbreak chamber (11) scooped up the stepped portion (30). Even so, it only crawls the inner surface of the return member (33) and does not reach the floor surface (32) above the stepped portion (30). That is, the earthworm (X) that has entered the first windbreak chamber (11) reaches the floor surface (32) above the stepped portion (30) by the stepped portion (30) and the return member (33). It cannot be done and is stopped on the lower floor (31).

    Thereafter, in the first wind chamber (11), the outer inner door (17) is opened after the entrance door (16) is closed. Thereby, the person who took off the shoes on the floor surface (31) below the stepped portion (30) can enter the second wind vent room (12).

    When a person enters the second wind vent room (12), the inner inner door (18) is locked by the interlock control so that the inner inner door (18) cannot be opened unless the outer inner door (17) is closed. . Therefore, since the outer inner door (17) is open, even if an insect enters the second wind chamber (12) from the first wind chamber (11), the inner door (18) ) Is closed, the insect is not allowed to enter the entrance room (13), but is stopped with the person in the second windbreak room (12).

    Thereafter, in the second wind chamber (12), the inner inner door (18) is opened after the outer inner door (17) is closed. Thereby, a person in the second windbreak room (12) can enter the entrance room (13).

    With the action of the insect repellent system (10) as described above, not only when the three doors (entrance door (16), outer inner door (17), inner inner door (18)) are closed, Insects are less likely to enter the entrance room (13). Also, near the entrance door (16) at night by an outdoor light (50) composed of low moth-lighting and UV cut film attached to the glass part of the exterior wall of the entrance door (16) and the first windbreak room (11) Even if is illuminated by light, nocturnal insects are difficult to get close to. This also makes it difficult for outdoor insects to enter the entrance room (13).

-Effect of Embodiment 1-
According to this insect repellent system (10), a room pressure adjusting device (20) is provided, and when the two doors (entrance door (16) and outer inner door (17)) of the first wind chamber (11) are closed. The chamber pressure on the entrance chamber (13) side of the outer inner door (17) (the chamber pressure of the second wind chamber (12)) is higher than the chamber pressure of the first wind chamber (11). The pressure is to be adjusted. Therefore, in the clearance of the outer inner door (17) on the entrance chamber (13) side of the first wind removal chamber (11), the second pressure on the entrance chamber (13) side is caused by the difference in the chamber pressure on both sides of the outer inner door (17). Air will circulate from the wind draft chamber (12) toward the first wind draft chamber (11). As a result, even if insects enter the first wind chamber (11) from the outside, the insects in the first wind chamber (11) remain in the first wind chamber from the gap between the outer inner door (17) and the frame. Due to the air flow blown to (11), it is impossible to enter the second wind removal chamber (12) on the entrance chamber (13) side through the gap. Therefore, according to this insect repellent system (10), insects can be reliably prevented from entering the entrance room (13) from the outside.

    Moreover, according to this insect-control system (10), the level | step-difference part (30) from which the outer side inner door (17) side is higher than the entrance door (16) side is formed in the floor surface of a 1st wind removal chamber (11). As a result, when a terrestrial insect (X) crawling on the ground invades the first windbreak chamber (11), the step (30) on the floor becomes a barrier, and the insect from the step (30) It becomes impossible to enter the outer inner door (17) side. That is, even if the earthworm (X) enters the building, it is stopped in the first wind chamber (11). Therefore, according to this insect repellent system (10), it is possible to more reliably prevent insects from entering the entrance room (13) from outside.

    Moreover, according to this insect-control system (10), since the return member (33) was provided in the level | step-difference part (30) of the floor surface of the 1st wind removal chamber (11), it invaded the 1st wind removal chamber (11). Even if there is an insect in the earthworm (X) that can crawl up the step (30), the return member (33) acts as a barrier, and the insect is on the upper floor of the step (30). Face (32) can no longer be reached. Therefore, according to this insect repellent system (10), it is possible to more reliably prevent insects from entering the entrance room (13) from outside.

    Moreover, according to this insect repellent system (10), when the two doors of the first wind vent chamber (11) are closed, the chamber pressure adjusting device (20) The chamber pressure of the first wind removal chamber (11) is adjusted to be higher than the outdoor atmospheric pressure. Therefore, in the gap between the front door (16) on the outdoor side of the first wind chamber (11), the pressure difference between the atmospheric pressure outside the door (16) and the room pressure of the first wind chamber (11). As a result, air flows from the first wind removal chamber (11) toward the outside. As a result, the insects in the outdoors scoop through the gap from the first wind chamber (11) through the gap between the entrance door (16) and the frame to the outside, and then sink into the first wind chamber (11). ) Can not enter. Therefore, according to this insect repellent system (10), it is possible to more reliably prevent insects from entering the entrance room (13) from outside.

    In addition, according to the insect repellent system (10), the second wind vent chamber (12) is further provided between the first wind vent chamber (11) and the entrance chamber (13). Therefore, when the entrance door (16) opens, even if an insect enters the first windbreak room (11), it must exceed two doors to reach the entrance room (13). Therefore, it is possible to more reliably prevent insects from entering the entrance chamber (13). In particular, a further wind chamber (second wind chamber (12) on the back side of the first wind chamber (11) provided with a step (30) that inhibits the invasion of earthworms (X) on the floor surface. ) Is effectively prevented from entering the entrance chamber (13) of the earthworm (X).

    Moreover, according to this insect repellent system (10), when the two doors of the second wind removal chamber (12) are closed, the room pressure adjusting device (20) In addition, it is configured to be adjusted so as to be higher than the outdoor first wind vent chamber (11) and lower than the chamber pressure of the entrance chamber (13). Therefore, when the two doors of the second wind vent chamber (12) are closed, the outer inner door (17) and the frame are caused by the difference in the chamber pressure between the first wind vent chamber (11) and the second wind vent chamber (12). The air flows from the second wind vent chamber (12) to the first wind vent chamber (11) in the space between the first wind vent chamber (11) and the insects that have entered the first wind vent chamber (11) due to this air flow. 12) Cannot enter. Similarly, when the two doors of the second wind vent chamber (12) are closed, the inner inner door (18) and the frame are caused by the difference in the chamber pressure between the second wind vent chamber (12) and the entrance chamber (13). Air flows from the entrance chamber (13) to the second wind vent chamber (12) in the gap between the insect and the insect that has entered the second wind vent chamber (12) cannot enter the entrance chamber (13). . Therefore, according to this insect repellent system (10), it is possible to more reliably prevent insects from entering the entrance room (13) from outside.

    In addition, according to the present insect repellent system (10), the three doors (16 to 18) are configured to be locked by the interlock control so that when one of the adjacent doors is opened, the other door is not opened. did. With this configuration, the two doors provided at the front and rear in each windbreak chamber (11, 12) do not open simultaneously. Therefore, there is no communication between the outside and the second wind chamber (12) via the first wind chamber (11), and the first wind chamber (11) and the entrance chamber (13) are the second wind chamber. There is no communication through the chamber (12). Therefore, according to this insect repellent system (10), it is possible to more reliably prevent insects from entering the entrance room (13) from outside. Fly insects such as flies may intrude into the entrance room (13) from the first windbreak room (11) at once when the three doors (16 to 18) are opened simultaneously. For this reason, the insect-control system (10) in which all the three doors (16 to 18) are not opened at the same time is particularly suitable for the entrance room (13) of flying insects such as flies among insects entering the building. ) Is effective in preventing intrusion.
