Abstract

PURPOSE:To make the shape of a package small, enable installation close to a wall surface, and reduce a housing space by providing an oscillating motor under a supporting body on which a head part having a vane motor is supported and eliminating the rearward projection of said head part. CONSTITUTION:An oscillating device is formed in such a way that a head part 6 having a vane motor 5 is supported on the upper part of a nearly L- shaped supporting body 7, whose lower part is rotatably installed on a lower member 13, and that an oscillating motor 22 is provided in a case 14 located on the lower part of the supporting body 7 to transmit an oscillating motion to the supporting body 7. Thus, since the oscillating motor 22 is provided in the case 14 positioned under the supporting body 7 on which the head part 6 having the vane motor 5 is supported, the head part 6 will not be projected rearward. Accordingly, the shape of a package can be made small, enabling installation close to a wall surface as well as housing in a small space.

is a blade electric motor housed in the head cover (61).
A vane (not shown) is coupled to the shaft (62a). (63) is 1 for feathers! The spindle is fixed to the motive (62) and extends downward, and is supported on the column (not shown) through the neckpiece (not shown), and (64) is the rear part and rear cover of the 11 moving rock (62) for the blade. A substrate fixed to (61b).

(65) is a 'gl rock for swinging that is fixed to the base plate (64), and its shaft (65a) protrudes downward. (66) is a crank fixed to the shaft C6'fi1, (6C is a oscillating iron pivotally supported by the crank (66)).

The conventional electric fan oscillating device is constructed as described above, and the oscillating J#3 tortoise motor 5) is arranged at the rear of the nine-blade electric motor (62), and its rotation is caused by the shaft (65a) and the crank (66).
and is transmitted to the swinging rod (67), forming a well-known swinging mechanism.

[Problem that the invention seeks to solve]

In the conventional fan oscillating device as described above, the oscillating movable machine (65) is arranged at the rear of the single-blade oscillating machine (62), so the fan part protrudes rearward. However, it is unavoidable that the packaging size becomes larger. Cannot be installed close to a wall.

Take up space for storage. There are other problems.

This invention was made to solve the above-mentioned problems.Since one head protrudes backward, the packaging shape can be made smaller, it can be installed close to a wall, and it can be stored in a narrow space. [The purpose of the present invention is to provide a swinging device for an electric fan.]

[Means for solving problems]

The swinging device for a fan according to the present invention supports a head having a blade motor on the upper part of a support formed in an L-shape, the lower part is pivotally connected to a lower member, and the support is A swinging motor is installed at the bottom of the swinging motor to transmit the swinging motion to the support.

[Effect]

In this invention, since the oscillating motor is provided at the lower part of the support supporting the ilt and I5j parts, the two heads do not protrude rearward.
