DETAILED DESCRIPTION OF THE INVENTION
Hot hot air from now indoor, the heat-sensitive material of the mounting cylinder body portion of the vent that opens to the outer wall surface to reach 72 ° C. of the reference and sensing, solder portion subjected to the outside surface of the auxiliary heat sensitive plates are first dissolved Begin. Then, both the sub-heat plate and the heat-sensitive plate detect and heat the abnormal hot air, so that the soldered part between the sub-heat plate and the heat-sensitive plate bonded together can not maintain the adhesive force and dissolve. To scatter. As a result, the restraining and holding of the damper on the left and right semicircular plates by the respective claw portions opposed to the left and right are lost, so that both semicircular plates are instantaneously opened around the support shafts to open the inner surface of the mounting cylinder. It comes into contact with the bent part of the part and completely closes the opening. This prevents leakage of high-temperature hot air to the outside .
[0007]
Since the heat-sensitive material comprising the heat-sensitive plate and the sub-heat-sensitive plate that restrains and holds the two semicircular plates of the damper together can no longer be used, the new heat-sensitive plate and the sub-heat-sensitive plate are used.
[0008]
That is, the worker loosens the screw that can be seen at the center of the lower end of the ventilation plate inside the hood that is on the outer wall surface outside the building. Then, since the central portion of the upper end portion of the peripheral flange portion of the mounting cylinder is removed from the latch piece at the center of the upper end portion of the ventilation plate, the ventilation plate provided with the hood body can be removed.
[0009]
Thus, with the inside of the mounting cylinder completely visible from the outside, the operator puts the semicircular plates of the damper in the closed state inside the mounting cylinder back to the parallel state again, and matches both the semicircular plates. At the center of the outer edge, the four opposite left and right claws of the new heat-sensitive plates are in contact with each other and restrained and attached.
[0010]
After installation, the center of the upper end of the bent portion provided on the peripheral flange of the mounting cylinder is again hooked to the hook at the center of the upper end of the vent plate having the hood body, and the through hole in the center of the lower end of the vent plate If the screw is screwed together with the through hole at the center of the lower end of the peripheral flange of the inner mounting cylinder , the replacement operation is completed.
