Description

[Detailed Description of the Invention] This invention relates to a blower that can be attached to either the ceiling or the wall.

Conventionally, ceiling-mounted fans were designed for ceiling-mounting only, and wall-mounted fans were designed for wall-mounting only.In the past, the blower body was rotatably mounted on a base that could be mounted on the ceiling or wall. Therefore, the air blowing range was widened.
For this reason, the balance of the blower body becomes a problem,
If the balance is poor, turning will not be smooth. In addition, because the mounting locations were limited, it was necessary to manufacture separate models for each.

This invention was developed in view of the above-mentioned drawbacks, and the object is to provide a blower that can be mounted on either a ceiling or a wall and has a wide air blowing range.

0 are formed at an angle of 7.5° with respect to the bottom surface, and are formed to face each other at an angle of approximately 90°.
Further, a screw hole 42 corresponding to the screw of the fixing piece 34 is bored in the side wall. 44 is a switch operation string.

This device is constructed as described above, and is assembled as follows. first. The electric motor 35 is screwed to the motor mounting foot 29a of the holder 29, and by positioning and rotating the electric motor 35 on the stepped portion 14a of the rear casing 4, the engaging foot 30 is engaged with the engaging portion 14 and the screw is screwed. screw hole 14b, through hole 30a, boss 4
5 and screwed into the screw boss 46,
The front casing 3, the rear casing 4, and the fixture 29 are fixed at the same time. A changeover switch 16 and a terminal block 18 are screwed to a boss 17 in the rear casing 4. In addition, a roller 20 is attached to the electric motor 23 for rotating the grill.
, attach this electric motor 23 for rotating the grill to the mounting plate 22 , further screw one side of this mounting plate so that it can rotate, and slidably engage the elongated hole of the other side with the boss 17 , and then install the spring 21 . . A blade 36 is fixed to the electric motor 35 by a fixing knob 37. In this way, the front casing 3 is fitted into the engagement groove 14 on the side plate 28.
By engaging the switch panel 9 with the recess 10 and joining it with the rear casing 4,
The engaging claw 11 is engaged with the engaging hole 6 and attached, and the grill attachment foot 24 is positioned on the attachment piece 8 and fixed by being screwed into the thread of the screw member 12 through the screw. Finally, the grille is fitted onto the shaft portion 25, the grille knob 43 is engaged, and the guard 38 is attached, thereby completing the assembly of the main body. Next, I will explain how to install this main unit on the ceiling or wall.
First, attach the fixing tool 39 to the ceiling or wall and insert the screw into the hole 41.
It sticks through. At this time, pay attention to the angle of the engaging collar 40. The engaging flange 40 and the engaging piece 32 of the fixed fixture 39 are positioned at a difference of 90 degrees, and the inclined surface 31 and the engaging flange 40 are brought into contact with each other. At this time,
The convex portion 31a is fitted and guided by the fixture 39, and the main body is rotated 90 degrees until it comes into contact with the engagement collar 40, so that the screw of the fixing piece 34 and the screw hole 42 are aligned,
By screwing, the main body is fixed to the ceiling or wall so that the shaft of the motor 35 is horizontal (as shown in FIGS. 5 and 7). On the other hand, if the fixture 39 is mounted on the wall at a position 180° different from the above, the main body will be tilted by 15° due to the 7.5° inclination angle of the fixture 39 and the 7.5° inclination angle of the holder 29. (as shown in Figures 6 and 8). In this way, when the electric motor 35 is driven by turning on the changeover switch 16, the blades 36 rotate to blow air, and the grill 2
The air is blown at a predetermined angle by the fins 27 of No. 6, and by driving the electric motor 23 for rotating the grill, the grill 26 is rotated around the shaft portion 25 via the roller 20, and the fins 27 blow the air. The direction is diffused and the air blowing range becomes wide. In this way, since the holder 29 engages with the engaging part 14, the blower body attached to the ceiling or wall is held by the engaging part and the entire engaging leg 30 of the holder 29, giving it strength. will be of high value. Furthermore, since the engaging portion 14 and the engaging foot 30 are formed with a predetermined curvature, they are difficult to come off and are not further rotated by the screw. Note that the holder 29 and the fixture 3
By setting the angle 9 arbitrarily, a mounting angle suitable for the installation location can be obtained.

As explained above, this invention allows the main body to be attached to a wall or ceiling at a predetermined angle by tilting either or both of the attachment parts of the holder and fixture at a predetermined angle. Since the grill can be rotated, the air can be blown in a wide range.
