Next, the operation will be explained. (The blower motor is omitted) and the grill of the push button switch 10.
When you press the ON button, the grill rotation motor 21
rotates, and at the same time, the rotational speed reduced by a speed reduction mechanism (not shown) built into this motor is transmitted to the grill rotation motor shaft 23, and the rubber pulley 1 on the outer periphery of the roller 18 attached to this shaft is transmitted to the grill rotation motor shaft 23.
The part 9 slides on the circumferential side 8 of the wind direction changing grille 7 to rotate the wind direction changing grille, thereby diffusing the wind sent out by the blades to the surrounding area. At this time, the wind direction change grill 7
Even if the peripheral side 8 is not necessarily concentric and is slightly deformed, the pulley is connected to the grill rotation motor 21.
Since the mounting plate 22 is pulled by a spring 29 and pressed against the wind direction changing grille circumferential side 8 with a constant force, it can rotate using the bearing boss part 14 of the front casing 2 as a bearing without slipping. Furthermore, since the mounting plate 22 has an elongated hole 30 so that the mounting plate 22 on the movable side B can freely slide around the fulcrum part A, the roller 18 may move slightly back and forth if the wind direction changing grille is deformed. It is now able to fully follow changes even if the robot moves rapidly. In this case, both the fulcrum part A and the movable part B are fastened to the boss 28 with a slight gap so that they can rotate freely.

In the past, the motor 21 for rotating the airflow direction changing grill was screwed directly to the mounting plate 22, and this mounting plate 22 was sandwiched between a seat 25 and a flat washer 26 and screwed to a boss 28 integrally molded with the casing 1. As a result, the vibration of the motor 21 for rotating the airflow direction changing grill was transmitted directly to the casing 1, and since the mounting plate 22 was screwed to the casing 1 via the seat 25, the small gap here would vibrate, producing noise and other drawbacks that deteriorated the quality of the product.

An embodiment of this invention will be described below with reference to FIGS. 4 to 9. In the figure, the roller 18 that rotates the wind direction changing grille 7 is comprised of a pulley 19 and a rim 20 made of a cushion material such as rubber, as shown in FIG.
It is composed of. The wind direction changing grill rotation motor 21 is attached to the first attachment plate at two locations with attachment screws 24 with a rubber cushion 33 in between. This first mounting plate 34 has three parts on the outer circumference.
The details will be explained later. There is a hole 38 for inserting the vibration isolating seat 32, and a slit 40 facing outward.
This is to make it easier to attach the vibration isolating seat 32. Further, the second mounting plate 35 is attached to the first mounting plate 3.
A hole 39 larger than the hole 38 of No. 4 is bored at a position opposite to the hole 38. These two mounting plates 34 and 35 have a hollow recess 32a formed at the center of their upper ends to make it easier to push in with the tip of a screwdriver, etc., and the tips are tapered so that they can be easily inserted into the second mounting plate 35. Hole 3 of mounting plate 34 of 1
8. Groove 3 with approximately the same diameter as the hole 39 of the second mounting plate 35
It is integrated with a vibration isolating seat 32 made of a cushion material such as rubber having 2b and 32c. Bushes 36 and 37 are integrally molded with self-lubricating resin (polyacetal, polyamide, etc.) at both ends of the second mounting plate 35 at the fulcrum A and movable side B in order to reduce sliding resistance there. has been done. The fulcrum part A is rotatably fastened to the boss 28 of the front casing 2 by a tightening screw 27 via a flat washer 26, and the movable part B is rotatably fastened to the boss 28 of the front casing 2 by a bushing as shown in FIG. 36 is flat washer 37
and the boss 28 so that it can slide between the coil spring 31 and the boss 28, and is attached with a tightening screw 27. Further, the second mounting plate 35 is pulled by a spring 29 so that the circumferential side 8 of the wind direction changing grille can always be pressed with a constant force even if the concentric circles of the wind direction changing grille 7 are not correct.

Next, the operation will be explained. First, when the grill ON button of the pushbutton switch 10 is pressed, the grill rotation motor 21 rotates, and at the same time, the rotation is decelerated by a speed reduction mechanism (not shown) built into this motor and is applied to the grill rotation motor shaft 23. As a result, the roller 18 attached to this shaft rotates, and the pulley 19 on the outer periphery of the roller rotates the circumferential side 8 of the wind direction changing grille 7, and the wind direction changing grille 7 diffuses the wind sent out from the blades 6 to the surrounding area. . The magnetic vibration of the grill drive motor 23 generated at this time is transmitted from the output shaft 23 of the grill drive motor 21 to the pulley 19, but the roller 18
Since the outer periphery of the wind direction changing grille 7 is made of a cushion material such as rubber, vibrations transmitted to the wind direction changing grille 7 are absorbed here. Also, since the cushion 33 is sandwiched and screwed between the grill drive motor 21 and the first mounting plate 34, most of the motor magnetic vibration is absorbed here. 3
4 and the second mounting plate 35 are connected to each other by a vibration isolating seat 32 made of a cushion material such as rubber, so even if the first mounting plate 34 vibrates, the vibration will not be transmitted to the next second mounting plate 35. In addition, the vibration noise generated from the slightest gap between the fulcrum part A and the movable part B is eliminated because the bushes 36 and 37 are integrally molded with the second mounting plate 35, and the vibration noise generated from the slightest gap between the fulcrum part A and the movable part B is eliminated. Since it is pressed against the boss 28 by the coil spring 31, vibration noise of the grill drive motor 21 can also be prevented. Also, wind direction change grill 7
Even if the circumferential side 8 is not concentric or is slightly deformed, the grille driving part is always pressed with a constant force by the spring 29, so the bearing boss 14 of the front casing 2 rotates as a bearing without slipping. It is possible. Pulley 19 of the roller 18, vibration isolating seat 3
It is even more advantageous to make the cushion 2 and the cushion 33 of the same material and the same hardness for vibration prevention.

In the above embodiment, the contact portion between the wind direction changing grille and the rubber roller is provided above the horizontal line passing through the center of rotation of the wind direction changing grille, but the contact portion is not limited to this, and may be provided below the horizontal line. I don't mind.

As described above, according to this invention, the magnetic vibration of the motor for rotating the wind direction changing grille is floated on the casing by the vibration isolating seat made of cushion material such as rubber, so a product with low noise can be manufactured, and even lower noise is desired. We are able to provide better electric fans in this environment.
