A ventilation port 21a as a ventilation opening is provided in the ceiling portion of the panel body 11, and a ceiling ventilation device VA is provided in the ventilation port 21a as a ventilation opening. The ceiling ventilation device VA includes a ventilation shade mount 21, a ventilation shade 31, and a ventilation filter 41. Between the ventilation shade mounting base 21 and the ventilation shade 31, a clearance (working dimension) for ventilation and work is provided, and the ventilation filter 41 can be freely attached to and detached from the inside upper portion of the ventilation shade mounting base 21. It is locked by the locking member.

FIG. 2 is a perspective view of the ventilation shade mounting base. In the figure, the ventilation shade mounting base 21 is provided with a ventilation opening 21 a, a ventilation shade attachment hole 21 b, and a locking member 51.
The ventilation shade mounting base 21 has a structure in which the four sides of the plate are bent upward, and a ventilation port 21a having a size necessary for ventilation is formed in four or more parts on the bottom surface. A ventilation filter 41 is provided so as to cover the ventilation port 21 a, and the ventilation filter 41 is attached to the ventilation shade mounting base 21 by a detachable locking member 51. The locking member 51 is formed of a plastic molded surface fastener or the like known as Magilock (registered trademark), and is fixed to the outer periphery of the bottom surface of the ventilation shade mounting base 21.

Next, the operation will be described.
When the ventilation filter 41 is removed, the ventilation filter 41 can be easily removed by placing a hand in the gap between the ventilation shade mounting base 21 and the ventilation shade 31 and picking and pulling the ventilation filter 41 with a finger. When the ventilation filter 41 is attached, the ventilation filter 41 can be easily attached by inserting the ventilation filter 41 through the gap between the ventilation shade mounting base 21 and the ventilation shade 31 and pressing the four sides of the ventilation filter 41 against the locking member 51 with fingers.

In this Embodiment 1, since the ceiling ventilation apparatus is attached to the outer side of the panel main body 11, the internal mounting space of the panel main body 11 can be utilized effectively. When replacing the ventilation filter 41, the work can be performed from the outside of the panel body 11, so that safety can be ensured, and since the work of removing screws and parts is unnecessary, the replacement work can be easily performed in a short time.
Further, the ventilation shade mounting base 21, the ventilation shade 31 and the ventilation filter 41 constituting the ceiling ventilation device have a simple component structure, and since the number of components is small, an economically superior device can be obtained.

  According to the first embodiment of the present invention, a cap-shaped member comprising a ventilation cap 31 covering the ventilation port 21 a as a ventilation opening provided in the ceiling portion of the panel main body 11, provided on the ceiling portion of the panel main body 11. Provided with a ventilation shade mounting base 21 for attaching a shade-shaped member made of the ventilation shade 31 with a gap for ventilation and work provided, and a ventilation opening as an opening for ventilation in the ceiling portion of the panel body 11 Since the ventilation filter 41 provided in 21a is attached to the ventilation shade mounting base 21 via a locking member 51 composed of a detachable plastic molded surface fastener or the like, the mounting efficiency in the panel can be improved, A ceiling ventilation device capable of easily and safely performing maintenance work can be obtained.

Embodiment 2. FIG.
A second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a front view showing the configuration of the draft shade mount in the second embodiment. FIG. 4 is a front view showing a state where the ventilation shade is attached to the ventilation shade mounting base in the second embodiment.
