JP 2002-303447 A JP 2002-295878 A

  Normally, in this type of ventilator, the degree of ventilation through the passage is controlled by determining the opening degree of the passage by the rotation of a closing member rotatably arranged in a frame defining the passage. Yes.

  In the ventilator, if a strong wind is generated outside the building (outdoors) when the passage is open, the strong wind may blow out into the room through the passage. The balloon based on the strong wind gives unpleasant feeling to the residents in the room and also causes dust and, if necessary, sand dust accompanying the balloon to soar into the room. Therefore, in such a ventilator, it is preferable to open and close the passage by rotating the closing member in response to the strength of the wind so that strong winds blown outside the building are not blown into the room. When a wind pressure sensor that electrically detects the wind pressure due to the wind is provided outside the building and the closing member is rotated by a detection electrical signal from this wind pressure sensor, it responds immediately to the strength of the wind. If the closing member is not rotated, it is difficult to completely prevent strong wind blowing from outside the building into the room.

  In order to improve the speed responsiveness of the rotation of the closing member, a drive device such as a large-sized electric motor with high response and high output is required. It becomes difficult to install in a ventilation port compactly.

  Therefore, as described in Patent Document 1, the applicant of the present invention is provided with a passage opening / closing means that is constantly urged to rotate so as to open the passage, and when an air flow at a certain speed or more is generated in the passage. And the ventilation apparatus provided with the air flow generation | occurrence | production means which rotates a channel | path opening / closing means so that a channel | path may be closed with this air flow was proposed.

  According to the proposed ventilator, it is possible to quickly open and close the passage in response to the wind blowing outside the building without the need for an electrical sensor, and it can be configured in a small size that does not require much space. A special effect can be obtained satisfactorily.

  Furthermore, recent single-family houses or apartment houses have improved airtightness. Therefore, if the ventilation is not performed properly, the room temperature rises easily and mites are easily generated. There is a risk of causing harmful effects on the human body due to an increase in the concentration of. From this point of view, when a ventilating opening is provided in the upper part of the outer wall of each room or in the window sash, and a ventilation mechanism comprising a shutter and a fan composed of a plurality of opening and closing plates is provided in this ventilation opening, for forced ventilation If the fan is rotated with the shutter open, and natural ventilation is performed, the fan is stopped with the shutter open, and if neither forced ventilation nor natural ventilation is performed, the shutter is It has been proposed to stop the rotation of the fan in the closed state.

  By the way, in the shutter of such a ventilation mechanism, the airtightness (sealing property) of the overlapping portions of the opening and closing plates cannot be so high in the closed state, and either natural ventilation or forced ventilation in the open state is possible. It is an obstacle to the air flow and does not efficiently generate the air flow.

  Therefore, a ventilator as described in Patent Document 2 has been proposed. According to such a ventilator, the airtightness can be improved, and the airflow can be efficiently performed in both cases of natural ventilation and forced ventilation. However, in the ventilator as long as it is explicitly described in the publication, it is difficult to perform effective natural ventilation due to the impediment of the blade means. There is a case where the means must be rotated, and it is not always satisfactory for the energy saving requirement.

  The present invention has been made in view of the above-mentioned points, and the object of the present invention is that natural ventilation and forced ventilation can be performed as necessary, and when natural ventilation is mainly performed. Ventilation that can respond quickly to the wind blown outside the building and can open and close the passage, and can use natural ventilation even when forced ventilation is mainly performed, thus satisfying energy saving requirements sufficiently To provide an apparatus.

  The ventilator according to the first aspect of the present invention has a first frame means having a pair of openings and defining a first passage communicating between the inside and outside of the building, and is rotatably arranged in the first passage. And a first passage opening and closing means for opening and closing the first passage, and an air flow that causes the first passage opening and closing means to generate a rotational moment based on lift in a direction to close the first passage. An air flow generating means for generating around the first passage opening and closing means based on the air flow, a second frame means having a pair of openings and defining a second passage communicating with the inside and outside of the building; In the open state of the second passage, the second passage is partitioned into two branch passages for natural air flow and forced air flow. A second passage opening / closing means having a partition member; The blade means that is trapped and rotatably disposed in one of the branch passages, and the first passage opening / closing means are rotated to forcefully close the first passage, and the second passage is opened and closed. Rotating means for opening and closing the passage for rotating the partition member to perform, and rotating means for generating forced air flow for rotating the blade means to generate a forced air flow in one branch passage.

  According to the ventilator of the first aspect, the first passage opening / closing means rotated by the passage opening / closing rotation means to be able to forcibly close the first passage is rotatable to the first passage. A partition member rotated by a passage opening / closing rotating means to open and close the second passage is arranged in the second passage, and is rotated by a rotating means for generating forced air flow to Since the rotary vane means for generating the air is arranged in one branch passage of the second passage, it can be naturally awakened through the first passage as needed, and also through the one branch passage. In the case where forced aspiration can be performed and natural ventilation is mainly performed in the first passage, air that causes the first passage opening / closing means to generate a rotational moment based on lift in a direction to close the first passage. The flow around the first passage opening and closing means based on the air flow in the first passage The first passage can be opened and closed in response to the wind blowing outside the building without the need for an electrical sensor to be generated by the air flow generation means, and forced ventilation is mainly performed. Even in this case, natural ventilation can be used via the other branch passage, and thus the energy saving requirement can be fully satisfied.

  The ventilator of the present invention may further comprise a control means for controlling the operation of the rotating means for opening and closing the passage and the rotating means for generating the forced air flow, like the ventilator of the second aspect. In this case, like the ventilator of the third aspect, it further comprises a manual operation panel for instructing the control means to operate the rotating means for opening and closing the passage and the rotating means for generating forced airflow, Thus, the manual operation panel opens and closes the first passage through rotation of the first opening and closing means by the rotation means for opening and closing the passage, and opens and closes the second passage through rotation of the partition member by the rotation means for opening and closing the passage. And the control means may be manually instructed to generate the forced air flow in one branch passage through the rotation of the blade means by the rotating means for generating the forced air flow. Like the ventilator of the first aspect, Detection means for detecting the velocity of the airflow of the airflow, and in this case, the control means may rotate the rotation means for opening and closing the passage and the rotation for generating the forced airflow based on the speed detection signal from the detection means. The operation of the means may be controlled.

  In the case of the ventilator according to the fourth aspect, as in the ventilator according to the fifth aspect of the present invention, the control means has a constant air flow speed in the first passage based on the speed detection signal from the detection means. If it is less than the value, for example, when there is substantially no wind outside the building and no wind-based airflow is generated in the first passage, the passage is opened and closed so that the partition member is rotated to open the second passage. The rotating means for generating forced air flow is operated so as to generate a forced air flow in one branch passage by operating the rotating means for rotating the blade means, and the air in the first passage. When the flow velocity exceeds a certain value, for example, when an air flow based on the wind outside the building is generated in the first passage, rotation means for opening and closing the passage is provided so as to close the second passage by rotating the partition member. Operate and stop the rotation of the blade means It is preferable that the rotating means for generating the forced air flow is operated so as to stop the generation of the forced air flow in one of the branch passages. According to such a ventilator, the speed detection signal from the detecting means is used. On the other hand, if the velocity of the air flow in the first passage is below a certain value, such as when there is no wind, forced ventilation can be performed by the operation of the rotating means for generating forced air flow. When the velocity of the air flow in the first passage exceeds a certain value, appropriate natural ventilation can be performed through the first passage, resulting in a more energy saving effect.

  The ventilator according to the second aspect, like the ventilator according to the sixth aspect of the present invention, commands the control means to operate between the manual operation and the automatic operation, and rotates and opens and closes the passage in manual operation. It may further comprise a manual operation panel for commanding the control means to operate the rotating means for generating forced air flow, and a detection means for detecting the speed of the air flow in the first passage. When the operation mode of manual operation is commanded to the control means, the panel opens and closes the first passage through the rotation of the first passage opening and closing means by the rotation means for opening and closing the passage, and is defined by the rotation means for opening and closing the passage. The control means can be manually commanded to open and close the second passage through the rotation of the member and to generate the forced air flow in one branch passage through the rotation of the blade means by the rotation means for generating the forced air flow. And control hand When the operation mode of the automatic operation is instructed from the manual operation panel, when the speed of the air flow in the first passage is below a certain value based on the speed detection signal from the detection means, the partition member Rotating means for generating a forced air flow so as to actuate the rotating means for opening and closing the passage so as to open the second passage and to rotate the blade means to generate a forced air flow in one branch passage When the air flow velocity in the first passage exceeds a certain value, the rotation means for opening and closing the passage is operated so as to close the second passage by rotating the partition member. At the same time, the rotation of the blade means is stopped so that the forced air flow generating rotation means is operated so as to stop the generation of the forced air flow in one of the branch passages.

  According to the ventilator of the sixth aspect, it is possible to perform both manual operation and automatic operation of the ventilator by manual operation with a manual operation panel, and in manual operation, the first passage is provided. Natural ventilation and forced ventilation through the second passage can be set as appropriate, and in automatic operation, natural ventilation through the first passage and forced ventilation through the second passage based on the speed detection signal from the detection means. Can be automatically selected to eliminate energy consumption for unnecessary forced ventilation.

  In the ventilator of the second or sixth aspect, as in the ventilator of the seventh aspect of the present invention, the control means is the case where the operation mode of the automatic operation is instructed from the manual operation panel, and When the speed of the air flow in the passage is below a certain value, the rotation means for opening and closing the passage is operated so that the first passage is forcibly closed by the first passage opening and closing means. When the operation mode of the automatic operation is instructed and the velocity of the air flow in the first passage exceeds a certain value, the forced closing of the first passage by the first passage opening / closing means is released. Accordingly, it is preferable to operate the rotating means for opening and closing the passage.

  The air flow generating means is preferably provided in the first passage opening / closing means so as to project over the first passage and change the air flow in the first passage, as in the ventilator according to the eighth aspect of the present invention. At least one current plate to be flowed is provided. If the current plate is too large, the first passage opening / closing means rotates and closes the first passage even if the air flow is slow in the first passage, while the width of the current plate is too high. The first passage opening / closing means does not rotate even in the air flow of the first passage, so the first passage cannot be closed, and the first passage opening / closing means is rotated by the air flow in the first passage at a flow rate of about 3 m / sec to 4 m / sec. In order to close the first passage, when the current plates are provided at both axial ends of the first passage opening / closing means, each of the current plates has an axial width of the first passage opening / closing means. Preferably, it has a width of 3% to 15%, more preferably 7% to 13%, and even more preferably about 10%, and one current plate is arranged at substantially the center in the axial direction of the first passage opening / closing means. When provided in the section, the current plate is preferably 7% to 25% of the axial width of the first passage opening / closing means, Ri preferably 10-20%, and even more preferably has a width of approximately 15%.

  The current transformer plate, like the ventilator according to the ninth aspect of the present invention, also causes the first passage opening / closing means to generate a rotational moment in the direction of opening the first passage by its own weight. If provided in the opening / closing means, the first passage opening / closing means does not rotate at a position eccentric from the center of gravity, or the first passage opening / closing means itself is generated at a position eccentric from the rotation center. It does not have to be formed. The current plate is preferably a curved plate that is curved so that a so-called lift is effectively generated in the first passage opening / closing means on the downstream side of the current plate, but it may be a simple flat plate.

  In a preferred example, the first passage opening / closing means includes a rotatable shaft and a closing member fixed to the rotatable shaft, as in the ventilation device of the tenth aspect of the present invention. The closing member may be fixed to the rotatable shaft so that its center of gravity is eccentric from the axis of the rotatable shaft so that the closing member is always urged to open the first passage by its own weight.

  In order to constantly bias the first passage opening / closing means so as to open the first passage, the first passage opening / closing means may be configured as described above. A weight is attached to the rotatable shaft or an elastic means such as a coil spring is connected to the rotatable shaft so that the first passage opening / closing means is always urged to rotate so as to open the first passage. May be.

Can be effectively prevented. As an example of the rotating force generating means for opening and closing the passage, an electric motor can be given as an example, but instead of this, a mechanism that can be manually operated such as an operation lever may be used.

  In one preferred example, the air flow generating means is a direction from the outside of the building to the inside of the building that causes a rotational moment to be generated in the first passage opening / closing means, as in the ventilation device of the twelfth aspect of the present invention. Is generated based on the air flow in the first passage.

  The second frame means may have a pair of side walls and a pair of horizontally long members bridging the pair of side walls, like the ventilation device of the thirteenth aspect of the present invention. Thus, each of the pair of horizontally long members is provided with a horizontally long seal member, and the partition member includes a protrusion that abuts each of the horizontally long seal members when the second passage is closed, and an open state of the second passage. The second passage may have a curved portion that divides the second passage into two branched passages, and a pair of closed portions that close both end faces of the curved portion.

  According to the ventilator of the thirteenth aspect, the closed state of the second passage having higher airtightness can be obtained by the contact between the horizontally long sealing member and the protrusion, and thus the ventilator It is possible to reliably prevent unintentional outside air from entering the room side to the room side from the outside of the building where the air conditioner is installed, dust intrusion, and unintentional discharge of air at the appropriate temperature from the unintended room side to the outside of the room.

  Like the ventilator according to the fourteenth aspect of the present invention, the curved portion is arranged between one opening and the blade means or between the other opening and the blade means in the closing of the second passage. It is good to be.

A so-called lift is generated in the closing member 42 as a rotational moment for rotating the closing member 42 in the A direction, and a rotational moment based on the lift is generated in the passage opening / closing means 9. When the passage 6 is closed by the closing member 42 and the air flow C is not generated in the passage 6, the closing member 42 is moved to the open position of the passage 6 by the rotational moment in the B direction due to the weight of the current change plate 49. (Fully open position) It is dynamic.

  The rotation means 21 rotates the shaft member 73 via the speed reducer 88 by the rotation of the output rotation shaft by the operation of the electric motor 85, and thus the passage opening / closing means 18 is rotated in the A and B directions around the rotation center 71. And the passage 13 is opened and closed by the partition member 17.

  The rotating means 21 rotates the shaft member 73 so that the partition member 17 closes the passage 13 when the disk 91 is rotated so that the closing member 42 can be rotated to the open position (full open position) of the passage 6. Conversely, when the disc 91 is rotated so as to close the passage 6 by the closing member 42, the shaft member 73 is rotated so as to open the passage 13.

  The rotating means 22 for generating the forced air flow includes an electric motor 81 having an output rotating shaft for rotating the shaft member 79 of the blade means 19 in the B direction. Is coupled to the shaft member 78 via a coupling (not shown), and the electric motor 81 is supported by the side wall portion 52 via a bracket 98.

  The rotating means 22 rotates the blade means 19 in the B direction by the operation of the electric motor 81, and generates a forced air flow from the opening 12 to the opening 11 in the branch passage 16 by the rotation of the blade means 19 in the B direction. It has become.

  The ventilation device 1 is mounted and held in a ventilation port 107 between a pair of lateral members 105 and 106 on an upper sash 104 of a building window 103 in which glass shoji 101 and 102 are fitted in the outer wall 7 of the building. Used. In the ventilator 1, a cover 108 for preventing rainwater from entering the openings 2 and 11 is attached to the lateral members 105 and 106 by welding or the like, and a dust-proof and bird-proof wire mesh is provided on the lower surface of the cover 108. 109 is attached via a screw or the like.

  In the ventilation device 1, each of the frame means 8 and 14 opens to the outside of the building 4 through the openings 2 and 11 that are one ends of the passages 6 and 13 and the other end of each of the passages 6 and 13. Are attached to the building outer wall 7 so as to open into the building 5 through the openings 3 and 12.

  In addition to the above configuration, the ventilation device 1 includes a control unit 23 that controls the operation of the rotation units 21 and 22, a manual operation panel 24 that instructs the control unit 23 to operate the rotation units 21 and 22, and the air in the passage 6. It further comprises detection means 125 for detecting the flow velocity, and restriction means (not shown) for restricting the passage opening / closing means 9 and the partition member 17 from rotating more than a certain amount in the A and B directions.

  The manual operation panel 24 is attached to a part of the building 5 that can be manually operated. The manual operation panel 24 commands the control means 23 to operate the manual operation and the automatic operation of the ventilator 1, and in the manual operation, the rotation means 21 and The control means 23 can be commanded to actuate 22, and in manual operation, the passage 6 is opened / closed via the rotation of the passage opening / closing means 9 by the rotation means 21 and the partition member 17 is rotated by the rotation means 21. The control means 23 can be manually commanded to open and close and to generate a forced air flow in the branch passage 16 through rotation of the blade means 19 by the rotating means 22.

  The control unit 23 controls the operation of the rotation units 21 and 22 based on the speed detection signal from the detection unit 125. Specifically, the control unit 23 controls the path based on the speed detection signal from the detection unit 125. When the air flow velocity of 6 is below a certain value, for example, there is substantially no wind outside the building 4 and no air flow based on the wind is generated in the passage 6, so that the air flow velocity in the passage 6 is substantially lower. If zero, the rotating means 21 is operated to rotate the partition member 17 to open the passage 13, and the blade means 19 is rotated to generate a forced air flow in the branch passage 16. When the velocity of the air flow in the passage 6 exceeds a certain value (including the case where the passage 6 is closed by the passage opening / closing means 9 due to strong wind), the partition member 17 is rotated. Passage 13 And it is adapted to operate the rotating means 22 so as to stop the forced occurrence of air flow in the branch passage 16 to stop the rotation of the blade means 19 actuates the rotation means 21 so as to close.

  Further, when the control member 23 rotates the partition member 17 to open the passage 13 and to generate a forced air flow in the branch passage 16, the blade means 19 periodically, for example, every hour. Is stopped, the generation of forced air flow in the branch passage 16 is stopped, and the rotation means 21 is operated to rotate the partition member 17 and the disk 91 to close the passage 13, while the closing member 42 is the passage. 6 so that the air flow can be generated in the passage 6 so that the air flow speed in the passage 6 is less than a certain value based on the speed detection signal from the detection means 125 at this time. It is judged whether or not, and if the air flow velocity in the passage 6 is not more than a certain value after a certain time, for example, 5 minutes, the partition member 17 is rotated again to open the passage 13. Rotating hand In the case where the speed of the air flow in the passage 6 exceeds a certain value while the rotation means 22 is operated so as to generate the forced air flow in the branch passage 16 by rotating the blade means 19 and the blade means 19, for example, outside the building 4 When the air flow based on the wind is generated in the passage 6 and the air flow speed in the passage 6 can ventilate the building 5, the forced air flow in the branch passage 16 is stopped and the closing member The state where 42 can be rotated to the open position of the passage 6 is maintained.

  When the closing member 42 can be rotated to the open position of the passage 6 so that an air flow can be generated in the passage 6, the passage 6 is closed by the closing member 42 due to strong wind and no air flow is generated in the passage 6. However, the closing of the passage 6 in such a strong wind is instantaneous and does not occur continuously for more than 5 minutes, for example, and the control means 23 keeps the speed of the air flow in the passage 6 constant within a certain time. When a speed detection signal indicating that the value is exceeded is received at least once from the detection means 125, it indicates that the speed of the air flow in the passage 6 is below a certain value even if the passage 6 is instantaneously closed by a strong wind. Even if the speed detection signal is received from the detection means 125 at least once, it is ignored.

  In the ventilator 1 described above, when manual operation, opening of the passage 6 and closing of the passage 13 and stopping of the forced air flow are manually set in the manual operation panel 24, the control means 23 for receiving such a command is: The electric motor 85 is operated so as to bring the disc 91 to the rotation position shown in FIG. 4 and the partition member 17 to the rotation position shown in FIG. 5, while the operation of the electric motor 81 is stopped so that the blade means 19 does not rotate. Let In this state, communication between the exterior 4 and the interior 5 via the passage 13 via the passage 13 is blocked by the partition member 17, while the exterior 4 and the interior 5 are communicated via the passage 6, The inside 5 of the building is naturally ventilated by the inflow of the air flow from the outside 4 to the inside 5 of the building 6 through the passage 6 or the outflow of the air flow, and vice versa. When this occurs, the closing member 42 is rotated in the direction A, and the passage 6 is automatically closed by the closing member 42. When manual operation, closing of the passage 6 and opening of the passage 13 and generation of the forced air flow are manually set in the manual operation panel 24, the control means 23 for receiving such a command causes the disk 91 to be placed in FIG. The electric motor 85 is operated so as to bring the partition member 17 to the rotation position shown in FIG. 13 at the rotation position shown, while the electric motor 81 is operated so that the blade means 19 rotates. In this state, communication between the building exterior 4 and the building interior 5 via the passage 6 is blocked by the passage opening / closing means 9, while the building exterior 4 and the building interior 5 are communicated via the passage 13, and the blade means 19 Due to the rotation, the air in the building 5 flows out of the building 4 through the branch passage 16 and the building 5 is forcibly ventilated. During forced ventilation, the interior 5 of the building can be naturally ventilated by the inflow of airflow from outside the building 4 to the interior 5 of the building via the branch passage 15 or vice versa.

  Further, in the ventilator 1, when the automatic operation is manually set on the manual operation panel 24, the control means 23 that receives such a command is supplied from the detection means 125 whose air flow velocity in the passage 6 is equal to or less than a certain value. When the speed detection signal is received, the electric motor 85 is operated and the blade means 19 is rotated so as to bring the disk 91 to the rotational position shown in FIG. 12 and the partition member 17 to the rotational position shown in FIG. The electric motor 81 is actuated so that a forced air flow is generated in the motor 16. In this state, communication between the building exterior 4 and the building interior 5 via the passage 6 is blocked by the passage opening / closing means 9, while the building exterior 4 and the building interior 5 are communicated via the passage 13, and the blade means 19 By rotation, the air in the building 5 flows out of the building 4 through the passage 13 and the building 5 is forcibly ventilated. Further, when the control means 23 receives a speed detection signal from the detection means 125 in which the speed of the air flow in the passage 6 exceeds a certain value, the disk 91 is at the rotational position shown in FIG. 4 and the partition member 17 is shown in FIG. The electric motor 85 is operated so as to bring it to the rotational position, and the operation of the electric motor 81 is stopped so that the rotation of the blade means 19 is stopped and no forced air flow is generated. In this state, communication between the building exterior 4 and the building interior 5 through the passage 13 is blocked by the partition member 17, while the building exterior 4 and the building interior 5 communicate with each other through the passage 6, When the inside of the building 5 is naturally ventilated by the inflow of the air flow through the passage 6 into the inside 5 or the outflow of the air flow in the opposite direction, and an air flow C of a certain speed or more, for example, 4 m / sec or more occurs When the closing member 42 is rotated in the A direction, the passage 6 is automatically closed by the closing member 42.

  The control means 23 does not need to operate the electric motor 85 so that the passage 13 is fully opened (the state shown in FIGS. 1 and 13) or fully closed (the state shown in FIG. 5). (Closed state) may be operated, and forced ventilation may be performed by rotating the blade means 19 in the half-open state of the passage 13. In this case, natural ventilation of the inside 5 of the building can be performed by the inflow of the air flow from the outside 4 to the inside 5 of the building via the branch passage 15 or the outflow of the air flow opposite thereto.

  As described above, according to the ventilation device 1, the frame means 8 that defines the passage 6 and the frame means 14 that defines the passage 13 are provided, and the passage 6 is closed to the passage opening / closing means 9 by the air flow generation means 10. In order to generate an air flow C in the direction and based on the air flow C of the passage 6 around the passage opening / closing means 9, which generates a rotational moment based on lift, the outside of the building without requiring an electrical sensor. The passage 6 can be opened and closed quickly in response to the wind blown at 4, and the passage 13 is divided into two branch passages 15 and 16 for natural air flow and forced air flow by the partition member 17, and one branch passage Since the vane means 19 is disposed on the partition 16, the partition member 17 does not get in the way, and in the case of forced ventilation when the vane means 19 is rotated, an air flow can be efficiently generated in the passage 13. Yes, one branch As a result of the air flow being generated in the passage 13 through the other branch passage 15 in addition to the passage 16, the ventilation can be performed more efficiently, and thus the energy saving requirement is sufficiently satisfied. Can do.

  In addition, in the ventilation apparatus 1, the passage opening / closing means 9 and the partition member 17 can be rotated to the positions where the passages 6 and 13 are in the half-opened state, the fully-opened state, and the fully-closed state by the rotating means 21. In addition to being able to open and close the opening (opening) and not to let the air in the room at an appropriate temperature escape, the air is blown into the building 5 based on the strong wind in the half-open state and the fully-open state of the passage 6, for example, into the room. Can also be prevented.

  Further, since the ventilation device 1 includes the transmission means 86 that allows the passage opening / closing means 9 to freely rotate toward the passage closing position, air is blown out into the building 5 based on strong winds in the half-open state and the fully-open state. Can be effectively prevented.

  Furthermore, in the ventilator 1, the passage 13 can be closed with a high degree of water tightness and air tightness, and it is possible to reliably prevent the entry of wind and rain into the building 5 when the passage 13 is closed, and the air conditioning is adjusted to an appropriate temperature. It is possible to effectively prevent leakage of air to the outside 4 of the building.

  In the ventilator 1, the passage opening / closing means 9 that is rotated by the rotation means 21 to forcefully close the passage 6 is rotatably disposed in the passage 6, and the rotation means 21 is provided to open and close the passage 13. This is necessary because the partition member 17 that is rotated by the rotation means 22 is disposed in the passage 13, and the rotary blade means 19 that is rotated by the rotation means 22 to generate a forced air flow is disposed in one branch passage 16 of the passage 13. Depending on the situation, the natural arousal can be performed through the passage 6 and the forced aspiration can be performed through the branch passage 16. When the natural ventilation is performed mainly in the passage 6, the passage 6 is closed. In order to generate an air flow that causes a rotational moment based on lift in the passage opening / closing means 9 to be generated by the air flow generation means 10 around the passage opening / closing means 9 based on the air flow C in the passage 6, an electrical sensor is provided. Need It is possible to quickly open and close the passage 6 in response to the wind blown outside the building 4 and to use natural ventilation through the other branch passage 15 even when forced ventilation is mainly performed. Can be fully satisfied with the energy-saving requirements.

  In the ventilator 1 described above, the pair of current transformation plates 49 are provided on both ends in the axial direction of the closing member 42 of the passage opening / closing means 9 by projecting from the convex surface 48 which is the surface of the passage opening / closing means 9 to the passage 6. Instead of or together with this, the current transformation plate 49 may be provided on the substantially central portion in the axial direction of the closing member 42 of the passage opening / closing means 9 by projecting from the convex surface 48 which is the surface of the passage opening / closing means 9 to the passage 6. In this case, the current plate 49 has a width d of 7% to 25%, more preferably 10% to 20%, and even more preferably about 15% of the axial width D of the closing member 42 of the passage opening / closing means 9. And projecting from the convex surface 48 to the passage 13.

  In the ventilator 1, the closing member 42 is always urged to rotate in the direction B by the weight of the pair of current transformer plates 49, but the center of gravity of the closing member 42 itself is decentered from the axis 46 of the rotatable shaft 41 and closed. The member 42 may be fixed to the rotatable shaft 41 so that the closing member 42 is always urged to rotate in the B direction.

  Further, according to the ventilation device 1, the contact state between the horizontally long seal members 55 and 56 and the projections 61 and 62 can provide a closed state of the passage 13 with higher airtightness, thus, It is possible to reliably prevent unintentional outside air, dust from entering the building 5 through the dust passage 13 and the similarly controlled air from being discharged from the unintended building 5 to the building outside 4.

  In the above, the openings 2 and 11 are arranged on the outside 4 side of the building, the openings 3 and 12 are arranged on the inside 5 side of the building, and the ventilation device 1 is provided on the upper part of the window 103. 11 may be arranged on the inside 5 side of the building, and the openings 3 and 12 may be arranged on the outside 4 side of the building, and the ventilation device 1 may be provided on the upper part of the window 103.
