There were also problems in the structure in which the passage could not be closed, and it was not possible to simply adopt the structure as a ventilation device.
- the opening and closing direction of the lid provided at the ventilation opening is switched as necessary, that is, two different specifications. It is desired to take measures to change the direction of operation in the opposite direction, such as when the lid is opened or closed, or when the closing force is opened. In particular, what is needed in the ventilator is to be able to switch the opening and closing direction of the lid without the need to add or change new parts.
- the present invention has been made in view of such circumstances, and the switching of the opening and closing direction of the lid can be easily set by a simple switching operation without using an extra new part. It is possible to adjust the amount of rotation of the lid with arbitrary characteristics, as well as the on-lift function and anti-lift function.
- a ventilator with a thermoactuator includes a lid body that is pivotally supported so as to open and close a ventilation port, A thermoactuator that operates as the temperature changes, a retainer member that forms a link mechanism for opening and closing the lid when the thermoactuator operates, and the lid is rotatable And a holder member that holds the retainer member so that the retainer member can be moved forward and backward.
- the engagement end provided on the lid member is engaged with the engaged portion of the retainer member to open and close the lid member.
- a ventilator with a thermoactuator according to the present invention is the ventilator with a thermoactuator according to claim 1, wherein the lid is changed from a closed state to an open state.
- the direction and position of installation of the thermoactuator, even when a deviation operation is selected between the first ventilation operation to be performed and the second ventilation operation to be changed to the open state force closed state Is not changed, and the support shaft portion of the lid body is commonly used.

- the closing operation is performed as the temperature rises such as the outside air temperature.
- the movement of the lid body causes the lid body or the retainer member to move to the lock portion. While being locked and locked to maintain the closed state, the pushing force of the piston may cause the engagement end of the lid body to be disengaged from the engaged portion of the retainer member, or may be in a disengaged state. Alternatively, the engaging end of the lid is engaged, and the retainer member having the engaged portion moves against the elastic supporting force to be absorbed! /.
- the ventilation opening can be opened when the outside air temperature or the room temperature is low and the temperature is cold, and can be closed when the temperature is hot. Furthermore, conversely, it may be required to configure the vent to close when the outside air temperature or room temperature is low and it is cold, and open when it is hot. In such a case, the operating direction and the installation position of the thermoactuator are not changed, that is, the lid is removed from the holder member while the thermoactuator is left as it is, and the mounting direction of the lid on the holder member is reversed. Further, it can be coped with by changing the urging direction by the coil spring.
- the lid is normally in a state of closing the ventilation opening, and is operated to gradually open the ventilation opening by the action of the thermo element as the temperature rises. At this time, the movement of the piston above the predetermined temperature is transmitted to the retainer member. The opening operation of the lid is locked by the retainer member being locked by the lock portion provided on the fixed portion side. It is like this.

It is unnecessary and can be assembled easily with force if the cost can be reduced, and the position of the rotating shaft of the lid is the same as the force, so there is no risk of increasing the size of the device and the shape is simple. There are advantages such as.

- a ventilation opening provided with such a ventilation device is sometimes opened in the summer or warm weather. If an air conditioner or the like is operated for cooling in this state, extra power will be consumed.
- the ventilator with a thermoactuator since it has a structure in which a closed state and an open state can be appropriately selected when it is cold, the installation position of the ventilation port provided with such a ventilator is arbitrary. Can be selected. For example, even if a ventilator that is open when it is cold is provided on the side of a ventilation fan in a kitchen or the like, the outside air can be exhausted in the shortest distance, so that the room temperature can be kept constant. Further, since the above vent can be closed in summer, an energy saving effect can be achieved.

- thermoactuator when a heating element such as a PTC heater is provided in a portion close to the temperature sensing portion of the thermoelement 23 provided as a thermoactuator, the above figure As in the case of 13, the opening / closing control of the lid 30 can be performed arbitrarily in combination with the case of ambient temperature. In other words, if this heating element can be controlled by using a controller provided near the ventilation device 10 or a controller remotely operated from the inside of the room, the opening and closing control of the ventilation port can be controlled according to the ambient temperature. It can be done arbitrarily in combination.
- the heating element may be an electric heater, for example, a chrome wire wrapped around it, or a PTC heater may be attached at an appropriate position, or A shape memory alloy that self-heats when an electric current is passed may be used.
- thermoactuator-equipped ventilator 10 according to the present invention is used for a home facility.
- the present invention is not limited to this, and the ventilator is used in various fields. Needless to say, it can be used as.
- FIG. 1 shows a first embodiment of a ventilator with a thermoactuator according to the present invention, (a) is a schematic cross-sectional view, and (b) is a schematic front view.
- FIG. 2 is a schematic exploded perspective view of the ventilator with a thermoactuator in FIG. 1.
- FIG. 3 (a), (b), (c), and (d) are enlarged views of the main part for explaining the opening and closing operation of the lid which is the main part in the ventilator of FIG.
- FIG. 4 (a), (b), (c), and (d) are diagrams for explaining the relationship between the movable shaft and the cam surface of the cam portion that characterize the present invention.
- FIG. 5 shows a case where the opening and closing direction of the lid in the ventilator with a thermoactuator in FIG. 1 is reversed, (a) is a schematic sectional view, and (b) is a schematic front view.
- FIG. 6 (a), (b), (c), and (d) are enlarged views of the main part for explaining the opening and closing operation of the lid, which is the main part in the ventilator of Fig. 5.
- FIG. 7 shows a second embodiment of a ventilator with a thermoactuator according to the present invention, in which (a) is a schematic sectional view and (b) is a schematic front view.
- FIG. 8 is a schematic exploded perspective view of the ventilator with the thermoactuator of FIG.
- FIG. 9 (a), (b), (c), and (d) are enlarged views of the main part for explaining the opening and closing operation of the lid, which is the main part in the ventilator of FIG.
- FIG. 10 (a), (b), and (c) are diagrams for explaining the relationship between the movable shaft and the cam surface of the cam portion that characterize the present invention.
- FIG. 11 shows a case where the opening and closing direction of the lid in the ventilator with a thermoactuator in FIG. 7 is reversed, (a) is a schematic sectional view, and (b) is a schematic front view.
- FIG. 12 (a), (b), (c), and (d) are enlarged views of the main part for explaining the opening / closing operation of the lid which is the main part in the ventilation device of FIG.
- FIG. 13 is a schematic view showing a modification of the ventilator with a thermoactuator according to the present invention.
