Abstract

PURPOSE:To prevent an air current from being curved with the aid of sutter blades, to enable reducing of the occurrence of a pressure loss and a circulating air, and to enable to perform an efficient ventilation with a low noise, by constituting a device such that a tilt angle of a shutter blade in an opening state parallels a direction in which air flows. CONSTITUTION:Openable shutter blades 6 are attached to the inside of a mounting frame so that they open at a time when an impeller turns. A pin 7 rotatably supports the shutter blades. With a driving motor 2 run, an impeller 4 turns, and the flow of air passes through between the opened shutter blades 6. In which case, a rotary shaft 3 is held at the same angle of inclination as that of the shutter blade 6 in an opening condition, and thereby an air current produced as a result of the rotation of the impeller 4 passes between the shutter blades 6 as shown by stream lines 8 without being curved. Simultaneously, a back pressure is low, and this reduces the production of a circulating current 9. The example is in the case of a ventilating device with shutter blades which performs a ventilation of both indoor and outdoor air, but the other ventilating device with blades or a blower with blades may produce the same effect that which is described above.

なる。Next, the operation of the ventilation system with shutter blades configured as described above will be explained. By rotating the drive motor (2), the impeller (4) rotates and a flow of air is generated that passes between the shutter blades (6) opened by its pressure or by other auxiliary means. Air flows out. If the shutter plate (6) is opened horizontally, there is a possibility that rainwater etc. may enter from the outside, and to prevent this, the shutter plate (6) is generally opened at an angle of inclination with respect to the horizontal. Therefore, the direction of air flowing horizontally due to the rotation of the impeller (4) is changed by the shutter blade (6), resulting in a flow similar to streamlines (8).

同時に流線（９）のような循環流を発生する。At the same time, a circulating flow like streamlines (9) is generated.

This is why 9) often occurs.

とを目的としている。This invention was made to eliminate the drawbacks of the conventional shutters as described above, and by arranging the impeller so that the air flow is parallel to the shutter blade when it is open, it reduces ventilation resistance. An object of the present invention is to provide a ventilation device with shatter blades that can prevent a decrease in ventilation efficiency and an increase in noise.

流（９）の発生は少なくなる。In the ventilation system with a shutter blade configured as described above, by rotating the drive motor (2), the impeller (4) is rotated and the air flow generated by the shutter blade (6) is opened. It flows out through the space. Here, since the rotation axis (3) is kept at the same inclination as the shutter blade (6) in the open state, the airflow generated by the rotation of the impeller (4) is not bent and is not bent into a streamline ( Shutter blade (6) like
). At the same time, due to the lower back pressure, less circulation flow (9) occurs.
