The conventional ventilation fan as described above is a ventilation fan for general household use and is relatively small, and since the guard 6 is made of resin, it is lightweight and the wind tunnel 7 etc. will not be deformed. however,
For example, in the case of large industrial ventilation fans, the above structure has a problem in that it is weak in strength and deforms.
この考案は、かかる問題点を解決するためにな
されたもので、大形の換気扇であつても変形する
ことなく、また、製造が容易な換気扇を得ること
を目的とする。 This invention was made in order to solve such problems, and the purpose is to obtain a ventilation fan that does not deform even if it is large in size and is easy to manufacture.

1 to 3 show an embodiment of this invention. In the figures, 1 to 4 indicate parts that are the same as or equivalent to the above conventional example, and 10 is a sheet metal plate that is detachably provided on the front surface of the main body 1. The frame body is formed into an L-shaped cross section, and notches 10a are provided at the four corners to prevent wrinkles from occurring during processing and to facilitate bending. 11 is the above notch 10
A reinforcing member formed slightly larger than a and spot welded to the frame 10, and an attachment portion 11a consisting of a hole.
is provided. Reference numeral 12 denotes a guard formed in a lattice shape using a wire rod, and the end portion thereof is provided with a threaded portion 12a that passes through the attachment portion 11a and is screwed.

成される。 In the ventilation fan configured as described above, the guard 12 is screwed to the frame 10 at the attachment portion 11a and attached to the main body 1. By driving the electric motor 2, the blades rotate, and indoor air is sucked in and exhausted from the guard side. Incidentally, since the frame body 10 is formed in an L-shape and has a notch 10a, wrinkles do not occur during bending, and the process is easy. Furthermore, by spot welding a reinforcing member having a hole 11a to this notch 10a, the strength is increased and a guard attachment portion is formed at the same time.

As explained above, in this invention, the frame is formed with a notch at the corner, and a reinforcing member with a guard attachment part formed in the notch is provided, thereby making it easier to process the frame. Further, there is an effect that the strength is increased and at the same time, the attachment part of the guard can be formed.
