And the extension 11 of the Further, the mounting portion 9 and the extension portion 11 have the same length as the horizontally long exhaust port 7.

  As shown in FIG. 5, the extension portion 11 has a width projecting from the exhaust port 7 in a side view, and guides the warm air exhausted downward from the horizontally long exhaust port 7 obliquely upward. It is

  The mounting portion 9 includes a spacer 13 for forming a gap for passing rain water between the mounting portion 9 and the drive body 3, and is mounted via the existing fastener 17 mounted on the drive body 3, A plurality of horizontally elongated holes 15 are provided at the top, bottom, left, and right. The spacer 13 is formed in a rectangular plate shape.

  The spacer 13 is formed by a projection 13A (see FIGS. 15, 16, 17, 19, and 24 described later) provided on the back of the attachment 13 by drawing from the surface of the attachment 9. May be

  In the example shown in FIG. 1, the exhaust port cover 1 attached under the upper exhaust port 7 is driven using the hole 15 on which the existing fastener 17 such as a bolt is located on the upper side of the mounting portion 9.

The small diameter shaft portion 22A and the large diameter head portion 22B are provided in series.

  When the front end side of the exhaust gas discharge plate 20 is fixed to the upper surface of the extension 11, as shown in FIG. 23A, the small diameter shaft 22A of the rivet 22 is engaged with the engagement hole of the exhaust gas discharge plate 20. The small diameter shaft portion 22A of the rivet 22 is inserted into the insertion hole 21A, which is 21. Then, as shown in FIG. The distal end side of the exhaust gas discharge plate 20 is fixed to the upper surface of the extending portion 11 by sliding to the 21 B side.

  In addition to the above description, the methods according to the above-described embodiments may be appropriately combined and used.

  Besides the above, although not illustrated one by one, the present invention is to be implemented with various modifications added thereto without departing from the scope of the invention.

  The exhaust port cover according to the present invention is widely used not only for mounting on the lower part of the horizontally long exhaust port provided in the power conditioner drive but also for the exhaust port provided in the drive of various devices. It is

  Further, in the exhaust port cover according to the present invention, it is possible not only to attach it to the power conditioner installed in the closed space by the concrete block, but also to provide the drive of the devices installed in various closed spaces. It is also widely used as an exhaust port.
