  On the other hand, conventionally, this type of vent is roughly divided into a manual vent that is manually opened and closed and an electric vent that is electrically operated. For example, when the outside air temperature is detected by a sensor, and the introduction of the outside air is desirable from the viewpoint of energy saving, the motorized ventilation port opens the ventilation port (ventilation path), and is not so. In this case, the opening / closing control is performed so as to be “closed”.

  However, since the electric vents as described above are electrically controlled for opening and closing, wiring for power supply and wiring for opening and closing control are necessary, which necessitates the cost of the vents and the cost of facility construction. There was a drawback of becoming expensive. By the way, the manual vent is low-cost, but it is cumbersome to open and close, and the energy-saving effect is lost due to forgetting to close it.

  Moreover, in the ventilating apparatus of this invention, it is desirable to provide the external air flow rate adjustment mechanism which opens and closes the said ventilation path according to the wind pressure of the external air which distribute | circulates the said ventilation path.

  In the vent hole device of the present invention, the bimetal is deformed according to the temperature of the outside air, so that the opening / closing member can be automatically driven to open and close according to the temperature of the outside air. Therefore, it is possible to automatically open and close the open / close member according to the desired outside air temperature without providing power supply wiring or drive control wiring as in the past, and it is inexpensive and reliably saves energy.

A filter 7 to be removed is provided. Furthermore, when the outside air G flows through the ventilation path R introduced from the outside air introduction port 4 into the ventilation path R (R2) from the bent portion R1 of the ventilation path R to the vicinity of the outside air supply port 5, A sound absorbing material 8 is provided for absorbing sound generated by the change in the flow direction of the outside air G at the bent portion R1 and suppressing the generation of abnormal noise. The sound absorbing material 8 is formed using, for example, stainless fiber or ceramic fiber.

  Further, the casing 1 of the present embodiment is formed with an opening / closing mechanism accommodation space H above a portion R3 extending from the outside air inlet 4 of the ventilation path R to the bent portion R1 inside the lateral direction S1. The opening / closing mechanism housing space H is formed by being surrounded by a side wall 1a along the wall of the building, a top plate 1b in which the outside air supply port 5 is formed, and an inner wall 1c that forms the ventilation path R. ing. The side wall 1a that forms the opening / closing mechanism housing space H is formed with a slit 1d that allows the opening / closing mechanism housing space H to communicate with the outside T1. Furthermore, an opening / closing plate advancing / retreating port 9 penetrating from the opening / closing mechanism housing space H to the ventilation path R is provided in a portion of the ventilation path R3 extending inward in the lateral direction S1 from the outside air inlet 4 of the inner wall portion 1c forming the opening / closing mechanism housing space H. Is formed.

  The opening / closing mechanism 2 opens and closes the ventilation path R by advancing / retreating from the opening / closing mechanism housing space H to the ventilation path R through the opening / closing plate opening / closing port 9, and opens / closes the opening / closing plate (opening / closing member). 10 and a drive mechanism 11 for driving the opening / closing plate 10 forward and backward. The drive mechanism 11 of the opening / closing mechanism 2 of the present embodiment is formed by bonding metal plates having different coefficients of thermal expansion, and includes a bimetal 12 formed in a spiral shape. The bimetal 12 is provided in such a manner that one end on the center side of the spiral is connected to the support member 13 fixed to the casing 1 and the other end is connected to the opening / closing plate 10 and accommodated in the opening / closing mechanism accommodation space H. It has been. At this time, the bimetal 12 is disposed on the side wall 1a side of the casing 1 (near the slit 1d formed in the side wall 1a).

  On the other hand, the flow rate adjusting mechanism 3 is provided in the ventilation path R, and includes a shaft portion 16 extending in the lateral direction S2 substantially perpendicular to the flow direction P of the outside air G flowing through the ventilation path R, and a substantially center in the vertical direction S3. One end of the flow rate adjusting plate 14 that is supported by the shaft portion 16 so as to be rotatable around the shaft portion and the inner wall portion 1c of the casing 1, and the shaft portion 16 of the flow rate adjusting plate 14 is on the upper end side. And an elastic body 15 such as a spring provided by connecting the other ends. Further, the flow rate adjusting plate 14 extends from the bent portion R1 of the ventilation path R to the portion R2 on the outside air supply port 5 side from the upper end side and from the outside air introduction port 4 of the ventilation path R to the inside of the lateral direction S1. It is provided in each of the portions R3 so that the one surface 14a on the lower end side faces the outside air inlet 4 side.

  In the vent hole device A of the present embodiment having the above-described configuration, the side wall 1a of the casing 1 is provided with the slit 1d, so that the temperature of the outside air G is accommodated in the opening / closing mechanism accommodation space H through the slit 1d. It is transmitted to the bimetal 12 of the mechanism 2. When the temperature of the outside air G is within a set temperature range such as 10 ° C. or more and 22 ° C. or less, for example, the bimetal 12 is shrunk so as to make its spiral into multiple windings according to the temperature of the outside air G. Following this, the opening / closing plate 10 connected to the other end of the bimetal 12 is pulled up from the ventilation path R into the opening / closing mechanism housing space H through the opening / closing plate opening 9. As a result, the ventilation path R is opened, the outside air G is introduced from the outside air introduction port 4 and flows through the ventilation path R, and is supplied to the room T2 from the outside air supply port 5 to perform ventilation.

  At this time, if the wind of the outside T1 is strong and the outside air G flows into the ventilation path R from the outside air introduction port 4 at a large flow velocity (large wind pressure), the strong wind outside air G is flow rate adjusting plate of the flow rate adjusting mechanism 3. 14, the flow rate adjusting plate 14 rotates in one direction around the shaft portion 16 so as to close the ventilation path R while elastically deforming the elastic body 15 by the wind pressure of the outside air G. Thereby, the flow path area of the ventilation path R becomes small automatically. Further, when the flow rate of the outside air G is reduced, the flow rate adjusting plate 14 is rotated in the other direction around the shaft portion 16 so as to open the ventilation path R by the elastic force of the elastic body 15, thereby the flow path of the ventilation path R. The area automatically increases. As described above, the flow rate adjusting plate 14 rotates according to the flow rate (wind pressure, and hence flow rate) of the outside air G introduced from the outside T1 into the ventilation path R, and the flow passage area of the ventilation path R changes in size. Therefore, during strong winds, the air flow path R is blocked by the flow rate adjusting plate 14, or the flow passage area is reduced, and the small amount of the outside air G is automatically adjusted from the outside air supply port 5 into the room T2. The

  Furthermore, in the ventilation opening device A of the present embodiment, even when sound is generated by the outside air G flowing through the ventilation path R, the sound is absorbed and attenuated by the sound absorbing material 8. Thereby, it is suppressed that abnormal noise is generated with the introduction of the outside air G into the room T2, and ventilation can be suitably performed without disturbing the living environment.

  In addition, since the outside air G flowing through the ventilation path R passes through the filter 7 before being supplied from the outside air supply port 5 to the room T2, the outside air G contains foreign matters such as insects, pollen, and dust. Even in this case, these foreign substances are captured by the filter 7 and removed. Therefore, also from this point, ventilation can be suitably performed without disturbing the living environment.

  On the other hand, when the temperature of the outside air G exceeds, for example, 22 ° C. and deviates from the setting range of the appropriate temperature, for example, the bimetal 12 is deformed so that the spiral of the bimetal 12 extends with a deformation amount corresponding to the temperature of the outside air G. And if the bimetal 12 deform | transforms, it will follow according to the deformation amount, the opening-and-closing plate 10 will advance into the ventilation path R from the opening-and-closing plate opening-and-retreat opening 9, and the ventilation path R will be closed. Further, when the temperature of the outside air G again falls within a set temperature range, the bimetal 12 returns to a contracted state so that the spiral of the bimetal 12 becomes multiple windings according to the temperature of the outside air G, and the ventilation path R is opened to open the outside air inlet 4. The outside air G is introduced from the outside air supply port 5 and is supplied from the outside air supply port 5 into the room T2.

  That is, in the vent hole device A of the present embodiment, the bimetal 12 senses the temperature of the outside air G, and the bimetal 12 is deformed according to the temperature of the outside air G, whereby the opening and closing drive of the ventilation path R by the opening and closing plate 10 is performed. Done automatically.

  Therefore, according to the ventilating apparatus A of the present embodiment, the bimetal 12 is deformed according to the temperature of the outside air G, so that the opening / closing plate 10 can be automatically opened and closed according to the temperature of the outside air G. Therefore, the opening / closing plate 10 can be automatically opened and closed according to the desired temperature of the outside air G without providing wiring for power supply and wiring for driving control as in the prior art. It is possible to provide the ventilating apparatus A capable of obtaining an energy saving effect.

  Moreover, in the ventilation opening device A of this embodiment, since the sound generated when the outside air G flows through the ventilation path R can be absorbed and attenuated by the sound absorbing material 8, the outside air G is taken into the room T2. Therefore, it is possible to suppress the generation of abnormal noise and to perform ventilation appropriately without disturbing the living environment.

  Furthermore, in the ventilating device A of the present embodiment, since the outside air G flowing through the ventilation path R passes through the filter 7 before being supplied from the outside air inlet 5 to the room T2, insects and Even when foreign matters such as pollen and dust are contained, these foreign matters can be captured and removed by the filter 7. Therefore, also from this point, ventilation can be suitably performed without disturbing the living environment.
