Description

  The present invention relates to a ventilating device that is installed on a wall of a building or the like and introduces outside air into a room for ventilation.

  Conventionally, buildings such as condominiums, office buildings, and houses are provided with ventilation openings (ventilation apparatus) in openings formed in walls and the like, and ventilation is performed by introducing outside air into the room through the ventilation openings. (For example, refer to Patent Document 1 and Patent Document 2).

JP 2000-121130 A JP 2003-161500 A

  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 to open and close, power supply wiring and open / close control wiring are required, which necessitates the cost of the vents and the cost of facility construction. There was a drawback of being 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.

  In view of the above circumstances, an object of the present invention is to provide an air vent device that can be automatically opened and closed according to the temperature of the outside air without requiring wiring for power supply or open / close control. To do.

  In order to achieve the above object, the present invention provides the following means.

  The ventilating device of the present invention is a ventilating device for introducing outside air from the outside to the inside of the building, and is introduced from the outside through the outside air introducing port, and supplies the outside air circulated through the ventilating passage to the inside. The external air supply port is formed as a plurality of slit holes, is provided with a plurality of slit-shaped communication holes, and is disposed to overlap the slit hole of the external air supply port. The open / close member that slides back and forth and opens / closes the slit hole to communicate / block the outside and the inside, and deforms according to the temperature of the outside air, and transmits the force generated by the deformation to the open / close member. And a bimetal for slidingly moving the opening and closing member.

  In this invention, when the bimetal detects the temperature of the outside air and expands and contracts according to the temperature of the outside air, the force generated by this deformation is transmitted to the opening and closing member, and the opening and closing member can be slid back and forth. . And since the plurality of slit-shaped communication holes are formed in the opening and closing member, for example, when the outside temperature is such that an energy saving effect is obtained by taking outside air into the building, the opening and closing member slides and the communication hole and When the outside air temperature is high or low, and the outside air temperature is increased by taking in outside air, the opening / closing member slides between the adjacent communication holes. The plate portion and the slit hole are overlapped so that the slit hole is closed, and the slit hole of the outside air supply port and the ventilation path can be automatically opened and closed according to the temperature of the outside air.

  The ventilating device of the present invention is a ventilating device for introducing outside air from the outside to the inside of a building, and is provided integrally with a shaft portion rotatably supported around an axis, and the outside air is circulated. And an opening / closing member that opens and closes the ventilation path with rotation of the shaft portion to communicate / block the outside and the inside, and deforms according to the temperature of the outside air, and the force generated by the deformation And a bimetal that rotates the shaft portion by transmitting the shaft to the shaft portion.

  In this invention, when the bimetal detects the temperature of the outside air and expands and contracts according to the temperature of the outside air, the force generated by this deformation is transmitted to the shaft portion, and the shaft portion can be rotated around the axis. The opening / closing member provided integrally with the shaft portion can be rotated together with the shaft portion. And, for example, when the outside air temperature is such that an energy saving effect can be obtained by taking outside air into the building, the opening / closing member is rotated and the ventilation path is opened, and the outside air temperature is high or low, and the outside air is taken in by taking in outside air. When the ambient temperature is such that the cooling load increases, the opening / closing member rotates and the ventilation path is closed, so that the ventilation path can be automatically opened and closed according to the temperature of the outside air.

  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. It is possible to provide a ventilating device that can obtain an effect.

Are formed as a plurality of slit holes penetrating from the surface to the lower surface.

  Furthermore, in the ventilation opening device A of the present embodiment, an opening / closing mechanism accommodating portion (opening / closing mechanism accommodating chamber) 6 adjacent to the ventilation path R and partitioned from the ventilation path R is formed by the casing 1. The opening / closing mechanism accommodating portion 6 is provided with an outside air temperature detection opening 7 in the front wall 1c on the outdoor T1 side, and the outside air temperature G is introduced into the inside through the outside air temperature detection opening 7, and the internal temperature is substantially equal to the temperature of the outside air G.

Here, the opening / closing mechanism accommodating portion 6 has the side wall portions 1d, 1e, the rear wall portion 1f, and the top plate portion so that the internal temperature is substantially equal to the temperature of the outside air G introduced from the outside air temperature detection opening 7. Desirably, a heat insulating material (not shown) is installed on the inner surface of 1 g.

  On the other hand, as shown in FIGS. 1 to 4, the opening / closing mechanism 2 of the present embodiment is slidably moved in the lateral front-rear direction S <b> 1 along the wall surface 3 of the building below the top plate portion 1 b of the casing 1. The plate-shaped opening / closing plate (opening / closing member) 10 and the bimetal 11 for slidingly moving the opening / closing plate 10 in the front-rear direction S1 are provided.

  The opening / closing plate 10 includes a plurality of slit-shaped communication holes 12 penetrating from the upper surface to the lower surface. The opening / closing plate 10 is slid in the front-rear direction S1, and the communication hole 12 overlaps the slit hole 5 of the top plate portion 1b in the up-down direction S2 in accordance with the sliding movement amount. It is formed so that the path R communicates with the room T2, and the plate portion 13 between the communication holes 12 adjacent to the slit hole 5 of the top plate portion 1b can be overlapped in the vertical direction S2 to close the slit hole 5. ing.

  Further, the opening / closing plate 10 has a front-rear direction S1 one end portion 10a side (front end portion side) arranged in the ventilation path R and overlapped with the top plate portion 1b of the casing 1, and the other end portion 10b side (rear end portion side). Extends from the side wall 1d of the casing 1 into the opening / closing mechanism housing 6. Further, as shown in FIG. 4, the opening / closing plate 10 is integrally provided with a regulating member 14 that reaches a predetermined sliding movement amount and abuts against one side wall portion 1 d of the casing 1 to restrict the sliding movement of the opening / closing plate 10. It has been.

  Next, as shown in FIGS. 1 to 4, the bimetal 11 of this embodiment is formed in a substantially U shape by bonding metal plates having different thermal expansion coefficients. The U-shaped bimetal 11 has one end 11 a fixed to the side wall 1 e of the casing 1 and the other end 11 b fixed to the other end 10 b of the opening / closing plate 10. It is arranged in the inside. At this time, it is desirable that the one end 11 a side and the other end 11 b side connected to the casing 1 and the opening / closing plate 10 are processed so as not to be affected by temperature as much as possible by covering them with a heat insulating material.

  In the ventilating device A of the present embodiment having the above-described configuration, the opening / closing mechanism housing portion 6 is provided with the outside air temperature sensing opening 7, so that the temperature of the outside air G is accommodated through the outside air temperature sensing opening 7. It is transmitted to the U-shaped bimetal 11 accommodated in the part 6. For example, as shown in FIG. 4A, when the temperature of the outside air G is equal to or lower than a certain low set temperature such as 10 ° C. or less, the bimetal 11 contracts, and the force generated by the deformation of the bimetal 11 is transmitted. Then, the opening / closing plate 10 slides backward so that the other end portion 10b side is drawn into the opening / closing mechanism housing portion 6, and the slit hole (outside air supply port) 5 of the top plate portion 1 b of the casing 1 and the plate of the opening / closing plate 10. The part 13 overlaps with the up-down direction S2. Thereby, when the temperature of the outside air G is equal to or lower than a low set temperature, the slit hole 5 of the outside air supply port is closed by the plate portion 13 of the opening / closing plate 10, and the ventilation path is automatically opened by the opening / closing plate 10. R enters a closed state, and the supply of the outside air G from the outdoor T1 to the indoor T2 stops.

  Next, when the temperature of the outside air G gradually rises from a certain low set temperature, the bimetal 11 begins to grow accordingly, as shown in FIGS. 4A and 4B, and the force generated by the deformation of the bimetal 11 And the opening / closing plate 10 slides forward, and the slit hole 5 of the top plate portion 1b of the casing 1 and the communication hole 12 of the opening / closing plate 10 gradually overlap. As a result, the slit hole 5 of the outside air supply port and the communication hole 12 of the opening / closing plate 10 communicate with each other, and the ventilation path R is opened, and the sliding movement amount of the opening / closing plate 10 and consequently the opening of the slit hole 5 and the ventilation path R are opened. An amount of outside air G corresponding to the degree 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 slit hole 5 of the outside air supply port. At this time, the amount of deformation of the bimetal 11 and thus the opening of the slit hole 5 of the outside air supply port are automatically adjusted according to the temperature of the outside air G. For this reason, the flow rate of the outside air G flowing through the ventilation path R and introduced into the room T2 is also adjusted according to the temperature of the outside air G. When the temperature of the outside air G reaches a certain intermediate temperature, all the slit holes 5 are overlapped with the communication holes 12 of the opening / closing plate 10 to open as shown in FIG. 5, the outside air G having a flow rate corresponding thereto is supplied to the room T2.

  Next, when the temperature of the outside air G becomes equal to or higher than a certain high set temperature such as 22 ° C. or more, as shown in FIG. 4C, the bimetal 11 is further extended, and the force generated by the deformation of the bimetal 11 is transmitted. Thus, the opening / closing plate 10 slides further forward. Accordingly, the slit hole 5 of the top plate portion 1b of the casing 1 and the plate portion 13 of the opening / closing plate 10 overlap in the vertical direction S2, and the slit hole 5 is closed. Thereby, when the temperature of the outside air G becomes a certain high temperature or higher, the ventilation path R is automatically closed by the opening / closing plate 10, and the supply of the outside air G from the outdoor T1 to the indoor T2 is stopped.

  When the temperature of the outside air G decreases, the ventilation path R is opened and closed by the reverse operation to the above, and the amount of air supplied to the outside air G is automatically adjusted.

  As described above, in the vent hole device A of the present embodiment, the bimetal 11 senses the temperature of the outside air G, and the bimetal 11 is deformed according to the temperature of the outside air G. The opening / closing drive is automatically performed, and the supply amount of the outside air G is automatically adjusted.

  Therefore, in the vent hole device A of the present embodiment, when the bimetal 11 detects the temperature of the outside air G and expands and contracts according to the temperature of the outside air G, the force generated by the deformation is an opening / closing plate (opening / closing member). 10 and the opening / closing plate 10 can be slid back and forth. Since a plurality of slit-shaped communication holes 12 are formed in the opening / closing plate 10, the opening / closing plate 10 slides and moves at an outside temperature at which an energy saving effect can be obtained by taking outside air G into the interior T2 of the building. The opening / closing plate 10 slides and moves when the outside air temperature is high or low and the outside air G takes in the outside air G and the heating or cooling load increases by overlapping the communication hole 12 to open the slit hole 5 of the outside air supply port. In addition, the slit hole 5 is overlapped with the plate portion 13 between the adjacent communication holes 12 so that the slit hole 5 is automatically closed according to the temperature of the outside air G, and the air passage R is automatically opened and closed. Can do.

  Therefore, according to the vent hole device A of the present embodiment, the bimetal 11 is deformed according to the temperature of the outside air G, so that the opening / closing plate 10 can be automatically driven to open and close according to the temperature of the outside air G. Thereby, the opening / closing plate 10 can be automatically opened and closed according to the temperature of the desired 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 that can surely obtain an energy saving effect.

Chamber 6, and the other end 16 b side is rotatably supported by a bearing 21. In addition, as in the first embodiment, the opening / closing mechanism accommodating portion 6 is provided with an outdoor temperature sensing opening 7 for communicating the outdoor T1 and the interior T2 in the front wall portion 1c on the outdoor T1 side. The opening 7 is formed so that the internal temperature becomes a temperature corresponding to the outside air temperature.

  In addition, as shown in FIGS. 6 and 8, the opening / closing mechanism 15 of the present embodiment includes two types of bimetals 19 and 20 formed by bonding metal plates having different coefficients of thermal expansion. Further, each of these two bimetals 19 and 20 is formed in a spiral shape, and one end 19a or 20a is fixed to the casing 1 or the bearing 21 or the like.

It is wound so as to enclose one of the bimetal 19 and the shaft portion 16 (as an inner surface).

  Further, as shown in FIG. 9, one end is connected to the outer peripheral surface of the shaft portion 16 on the other end portion 16 b side of the shaft portion 16 disposed in the opening / closing mechanism accommodating portion 6, and A flat plate-like pressing plate (pressing member) 22 that protrudes radially outward is integrally provided. The pressing plate 22 is provided with the plate surface directed in the circumferential direction of the shaft portion 16. The other bimetal 19 and the other bimetal 20 have the other ends 19b and 20b arranged at substantially the same position in the direction of the axis O1 of the shaft portion 16, and the center of the axis surface O1 of the shaft plate 16 and the axis portion 16 of the shaft portion 16. It arrange | positions so that it may oppose in the circumferential direction.

  In addition, as shown in FIG. 7, the outside air G flowing through the ventilation path R passes through the ventilation path R of the casing 1 as necessary, and foreign matter such as insects, pollen, and dust contained in the outside air G. A filter 23 that captures and removes is provided. Further, sound generated by the outside air G flowing through the ventilation path R introduced from the outside air introduction port 4 in the ventilation path R, or by the change of the circulation direction of the outside air G in the ventilation path R, etc. A sound absorbing material 24 is provided for absorbing noise and suppressing the generation of abnormal noise. The sound absorbing material 24 is formed using, for example, a stainless fiber or a ceramic fiber.

  In the vent hole device B of the present embodiment having the above-described configuration, the opening / closing mechanism housing portion 6 is provided with the outside air temperature sensing opening 7, so that the temperature of the outside air G is accommodated through the outside air temperature sensing opening 7. It is transmitted to the two bimetals 19 and 20 of the opening / closing mechanism 15 accommodated in the part 6. When the temperature of the outside air G is equal to or lower than a certain low set temperature such as 10 ° C. or less, for example, as shown in FIG. 9A, one bimetal 19 is contracted and rotated, and the other bimetal 20 is extended. The other end 20b of the other bimetal 20 contacts the plate surface of the pressing plate 22 and presses the pressing plate 22.

  Thereby, below a certain low set temperature, as shown in FIG. 7B and FIG. 9A, the pressing plate 22 is pressed by the other bimetal 20, and the shaft portion 16 is in one direction centered on the axis O1. Together with this, the opening / closing plate 17 rotates in one direction P1 about the axis O1 and closes the ventilation path R. Therefore, when the temperature of the outside air G is equal to or lower than a low set temperature, the bimetals 19 and 20 are deformed according to the temperature of the outside air G, and the shaft portion 16 is generated by the force generated by the deformation of the bimetals 19 and 20. The air passage R is automatically closed by the opening / closing plate 17 rotated with the rotation of the shaft portion 16, and the supply of the outdoor air G from the outdoor T1 to the indoor T2 is stopped.

  Next, as shown in FIGS. 7A and 9B, when the temperature of the outside air G gradually rises from a certain low temperature, the other bimetal 20 starts to shrink accordingly, and the elastic body 18 The opening / closing plate 17 is rotated in the other direction P2 about the axis O1 by the urging force, and the ventilation path R is gradually opened. As a result, the amount of outside air G corresponding to the amount of rotation of the opening / closing plate 17 and thus the opening of the ventilation path R is introduced from the outside air introduction port 4 and circulates through the ventilation path R, and from the outside air supply port 5 to the room T2. It is aired.

  As described above, when the temperature of the outside air G gradually rises from a certain low temperature, one of the bimetals 19 starts to grow accordingly. When the temperature of the outside air G reaches a certain set temperature, the other bimetal 20 contracts and the opening / closing plate 17 rotates in the other direction P2 by the urging force of the elastic body 18, as shown in FIG. 9C. And the ventilation path R will be in a fully open state. In addition, in this way, in a state where the temperature of the outside air G has reached a certain intermediate temperature setting temperature, one of the bimetals 19 extends, and the other end 19b contacts the plate surface of the pressing plate 22. That is, when the opening / closing plate 17 is rotated in the other direction P2 and the ventilation path R is fully opened, the other ends 19b, 20b of the one bimetal 19 and the other bimetal 20 are on the plate surface of the pressing plate 22. Both bimetals 19 and 20 are formed so as to contact each other.

  Next, as shown in FIGS. 7A and 9D, when the temperature of the outside air G further rises from a certain set temperature of the intermediate temperature, the other bimetal 20 further shrinks accordingly, and the other bimetal 19 extend. Thereby, this time, the pressing plate 22 is pressed by one of the bimetals 19, the shaft portion 16 starts to rotate in one direction P1 centered on the axis O1, and the opening / closing plate 17 rotates in one direction P1 centered on the axis O1. The ventilation path R is gradually closed, and the amount of supply of the outside air G decreases.

  Then, as shown in FIGS. 7B and 9E, when the temperature of the outside air G becomes equal to or higher than a predetermined high temperature such as 22 ° C. or higher, the other end 19b of one bimetal 19 comes into contact. The pressing plate 22 is pressed, and the opening / closing plate 17 is held in a state rotated in one direction P1 about the axis O1, and the ventilation path R is closed by the opening / closing plate 17. Therefore, when the temperature of the outside air G is equal to or higher than a high set temperature, the ventilation path R is automatically closed by the opening / closing plate 17, and the supply of the outside air G from the outdoor T1 to the indoor T2 is stopped. .

  Similarly to the first embodiment, when the temperature of the outside air G falls from a certain high temperature, the ventilation path R is opened and closed by the reverse operation to adjust the supply amount of the outside air G automatically. Is done.

  Thus, also in the ventilating apparatus B of the present embodiment, the bimetal 19 and 20 senses the temperature of the outside air G, and the bimetal 19 and 20 is deformed according to the temperature of the outside air G. The opening and closing drive of the ventilation path R is automatically performed, and the supply amount of the outside air G is automatically adjusted accordingly.

  Therefore, in the vent hole device B of the present embodiment, when the bimetals 19 and 20 detect the temperature of the outside air G and expand and contract according to the temperature of the outside air G, the force generated by the deformation is applied to the shaft portion 16. The shaft portion 16 can be rotated around the axis O <b> 1, and the opening / closing plate (opening / closing member) 17 provided integrally with the shaft portion 16 can be rotated together with the shaft portion 16. When the outside air temperature is such that an energy saving effect can be obtained by taking the outside air G into the interior T2 of the building, the open / close plate 17 is rotated and the ventilation path R is opened so that the outside air is high or low and the outside air G is taken in. Thus, at the outside air temperature at which heating or cooling load increases, the opening / closing plate 17 rotates and the ventilation path R is closed, so that the ventilation path R can be automatically opened and closed according to the temperature of the outside air G.

  Therefore, also in the ventilating apparatus B of the present embodiment, the opening and closing plate 17 can be automatically driven to open and close according to the temperature of the outside air G by deforming the bimetals 19 and 20 according to the temperature of the outside air G. . This makes it possible to automatically open and close the open / close plate 17 according to the desired outside air temperature without providing power supply wiring or drive control wiring as in the prior art. It is possible to provide the ventilating apparatus B capable of obtaining an energy saving effect.

  Further, in the ventilation opening device B of the present embodiment, the open / close plate 17 is disposed in the ventilation path R and is urged by the elastic body 18, so that strong wind and high pressure outside air G is generated from the outside air introduction port 4. When introduced, the open / close plate 17 is automatically rotated by the pressure of the outside air G, and the ventilation path R is closed. Thus, the ventilation path R can be automatically opened and closed not only by the temperature of the outside air G but also by the pressure of the outside air G, and it is possible to supply and ventilate the outside air G to the room T2 more suitably. Become.

  Further, a sound absorbing material 24 is provided in the casing 1, and the sound generated when the outside air G flows through the ventilation path R is absorbed by the sound absorbing material 24 and attenuated. Thereby, by taking the outside air G into the room T2, it is possible to suppress the generation of abnormal noise, and ventilation can be suitably performed without disturbing the living environment.

  Further, a filter 23 is provided in the casing 1 so that the outside air G flowing through the ventilation path R passes through the filter 23 before being supplied from the outside air supply port 5 to the room T2. Thereby, even if foreign matter such as insects, pollen, and dust is included in the outside air G, these foreign matters can be captured and removed by the filter 23 and can be suitably used without disturbing the living environment. Ventilation can be performed.

  The first and second embodiments of the ventilating apparatus according to the present invention have been described above. However, the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

  For example, as shown in FIG. 10, an exhaust fan 25 may be provided on the indoor T2 side, and the exhaust fan 25 may be operated when it is determined that the outside air condition is suitable for introducing outside air. In this case, in addition to automatically adjusting the supply amount of the outside air G by opening and closing the opening and closing plate 10 according to the temperature of the outside air G, the supply amount of the outside air G (in the room T2 by the operation of the exhaust fan 25). Uptake). Thereby, it becomes possible to take in outside air G more efficiently.

  Further, in the second embodiment, the opening / closing mechanism 15 includes two bimetals 19 and 20 formed in a spiral shape, and is arranged so as to wind these bimetals 19 and 20 around the shaft portion 16, and the temperature of the outside air G Accordingly, the bimetals 19 and 20 are expanded and contracted to automatically rotate the shaft portion 16 and thus the opening / closing plate 17 to open and close the ventilation path R.

  On the other hand, as shown in FIGS. 11 and 12, for example, two bimetals 26 and 27 formed in a U-shape are provided, one end is connected to the shaft portion 16, and the outer side in the direction orthogonal to the axis O1 (outside in the circumferential direction). The opening / closing mechanism 29 may be configured by including a pressing rod (pressing member) 28 projecting from the above. At this time, one of the bimetals 26 is installed with only one end 26a fixed to the casing 1 (side wall portion 1d), and the straight bar portion 26b on the one end 26a side where the pressing rod 28 extends parallel to each other. And a straight rod portion 26d on the other end 26c side, and a predetermined gap between the straight rod portion 26d on the other end 26c side. The other bimetal 27 is installed with only one end 27a fixed to the casing 1 (side wall portion 1d), and the pressing rod 28 is outside the straight rod portion 27d on the other end 27c side (on the other end 27c side). The straight rod portion 17d is placed between the straight rod portion 27b on the one end 27a side and the straight rod portion 27d on the other end 27c side, with a predetermined gap therebetween. The

  When the opening / closing mechanism 29 is configured in this way, the bimetals 26 and 27 are installed with the other ends 26c and 27c as free ends. For example, when the temperature of the outside air decreases, When the space 27 is contracted and the distance between the straight rod portions 26b, 27b on one end side and the straight rod portions 26d, 27d on the other end side is narrowed and the temperature of the outside air rises, each bimetal 26, 27 expands, The distance between the straight rod portions 26b and 27b and the straight rod portions 26d and 27d on the other end side is increased. As a result, when the temperature of the outside air decreases, the straight rod portion 26d on the other end side of one bimetal 26 abuts against the pressing rod 28 to press the pressing rod 28, and the shaft portion 16 is unidirectional P1 around the axis O1. Rotate to. Further, when the temperature of the outside air rises, the straight rod portion 27d on the other end side of the other bimetal 27 comes into contact with the pressing rod 28 to press the pressing rod 28, and the shaft portion 16 moves in the other direction P2 around the axis O1. Rotate. Therefore, these U-shaped bimetals 26 and 27 press the pressing rod 28, and the urging force of the elastic body 18 acts on the opening and closing plate 17, so that the temperature of the outside air G is increased as in the second embodiment. Accordingly, the air passage R can be opened and closed by rotating the shaft portion 16 and thus the opening / closing plate 17 in the forward and reverse directions, and the supply amount of the outside air G can be automatically adjusted. That is, even when the opening / closing mechanism 29 is configured as described above, it is possible to obtain the same operational effects as those of the second embodiment.
