Description

[Detailed description of the invention] Industrial applications The present invention relates to an electric fan having oscillating means.

Conventional configuration and its problems As shown in Figures 1 and 2, conventional electric fans of this type automatically oscillate only in the left and right directions, and oscillate vertically by manually tilting the neck piece. As a result, there was a problem in that the wind could only reach a portion in the vertical direction.

In addition, a fan has been proposed in which horizontal oscillation is performed by a oscillating motor housed in a neck piece, and vertical oscillation is performed by decelerating the rotation of the main shaft of the main motor using a speed reducer. According to the above, since the vertical swing is performed by the rotation of the main shaft of the traction motor, there is a problem that when the rotation of the main shaft of the traction motor changes due to speed adjustment, the swing period also changes accordingly. The vertical swinging mechanism is constructed with a mechanical clutch machine, and the horizontal swinging mechanism is constructed with an electric switch, which also has the problem of requiring a complicated assembly process to configure the operating mechanism. Ta.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
The purpose of the present invention is to provide a high-value-added and inexpensive electric fan by making the vertical and horizontal vibrations of the fan part a constant-period vibration operation regardless of the rotation of the main shaft of the main motor, and by creating a mechanism that is easy to assemble. do.

Structure of the Invention In order to achieve the above object, the electric fan oscillation device of the present invention includes a main motor, a vertical oscillation motor and a horizontal oscillation motor located behind the main motor,
A support arm that rotatably supports the main motor in the vertical direction, a mounting plate with a core rod attached below, and a neck piece that supports the core rod rotatably in the left and right direction by inserting the core rod. , the vertical oscillation motor and the lateral oscillation motor are mounted on the mounting plate so as to be located behind the main motor, and the vertical oscillation rod is connected to the main motor and the vertical direction. The oscillating motors are connected, and the left-right oscillating rod connects the lateral oscillating motor and the neck piece, and the electric fan is configured to have means for supplying electricity to the vertical oscillating motor and the left-right oscillating motor. This makes it possible to oscillate the head at the same time or independently.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 6. 1 is a main electric motor, and a propeller-type blade 2 is attached to its rotating shaft. A support stand 3 is attached to the front surface of the main electric motor 1, and this support stand 3 is attached to a support arm 4 so as to be rotatable in the vertical direction. A vertical swing motor 6 and a horizontal swing motor 7, which are held by a mounting plate 5 integrated with a support arm 4, are arranged behind the main motor 1. An upper part of a core rod 6 is fixed to a mounting plate 5 at the lower part of the main electric motor 1. And the core rod 8 is the neck piece 9
It is rotatably supported in the left-right direction by a bearing portion 10 of the present invention. Note that the neck piece 9 is connected to the upper part of the base 11. A crank A12 is fixed to the rotating shaft of the vertical oscillation motor 6, and the crank A12
is connected to the main motor 1 by a rod A13. In addition, a crank B14 is fixed to the rotating shaft of the left and right oscillating motor 7, and this crank B14 is attached to the rod B.
15 to one end of the neck piece 9. As shown in FIG. 5, a main switch 16 controls the speed of the main motor 1 and opens and closes the power supply for the lateral oscillation motor 7 and the vertical oscillation motor 6. Further, switching between the vertical oscillation motor 6 and the lateral oscillation motor 7 is performed by a changeover switch 17, and the vertical oscillation motor 6 and the lateral oscillation motor 7 can be rotated independently or both can be rotated simultaneously. The circuit is configured like this.

In the above configuration, when the main switch 16 is turned on and the changeover switch 17 is set to rotate the vertical oscillation motor 6, the rotation shaft of the vertical oscillation motor 6 rotates, the rotation is transmitted to the crank A12, and the rotor is rotated. The main electric motor 1 connected to A13 is vibrated once per revolution of the crank A12 in the vertical direction.

Similarly, when the main switch 16 is turned on and the changeover switch 17 is set to rotate the left-right swing motor 7, the rotation of the rotation shaft of the left-right swing motor 7 is transmitted to the crank B14, and the rod B15 is connected to the neck piece 9. By making the mounting plate 5 oscillate in the left and right directions around the core rod 10 because of the connection, the traction motor 1 attached to the support stand 3 supported by the support arm 4 can oscillate vertically. One neck vibration operation is performed for one rotation of the motor 6.

When the changeover switch 17 is set to rotate both head oscillation motors 6, 7, the above-mentioned vertical and lateral neck vibration operations are performed simultaneously.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, it is possible to obtain vibrations with a constant period that is not affected by the rotational speed of the main motor, and moreover, in vertical, horizontal, and both vertical and horizontal directions. wide range of reach,
This has the effect that a high value-added electric fan can be supplied through a simple assembly process.
