Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swinging device for a fan.

2. Description of the Related Art In recent years, the interior design of fans has been emphasized, and there is a remarkable trend toward compactness and thinness.

A conventional swinging device for a fan will be described below. FIG. 3 is a side cross-sectional view of a conventional swinging device for an electric fan. A frame 2 is fixed to the side of a main motor 1, and the frame 2 is supported by a receiving member 3 and a lifting shaft 2a so that it can be raised and lowered. ing. A fixed plate 7 that supports a swing motor is attached to the rear of the main motor 1, and a crank 5 attached to the output shaft of the swing motor 4 and the receiving object 3 are rods 6.
Thus, the respective joint points are rotatably connected to each other.

The operation of the swinging device for a fan configured as described above will be described below.

First, when the swinging electric motor 4 rotates, the crank 5 fixed to the output shaft rotates to displace the rod 6 into a fan-shaped reciprocating motion about the shaft 3a. The main electric motor 1 configured as described above reciprocates as a relative movement with respect to the receiving object 3 about the elevation shaft 2a.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described conventional configuration, since the swinging electric motor is mounted in the longitudinal direction at the rear of the main electric motor, the rear portion of the electric motor protrudes abnormally, impairing the appearance as an interior. There was a problem that the packaging talent would be large.

In addition, as shown in Japanese Utility Model Laid-Open No. 60-185092, in the case where a main shaft is extended to the rear of the main motor and a swing mechanism combined with a rotating plate is attached, this swing mechanism is located behind or behind the main motor. It had a problem that it greatly protruded to the surrounding area.

The present invention is to solve the above conventional problems,
An object of the present invention is to provide a swinging device for an electric fan, which has a thin design with a good-looking appearance and which has a short front-rear length and which can reduce the packaging talent.

Means for Solving the Problems In order to achieve this object, a swinging device of a fan according to the present invention supports a main electric motor rotatably on both sides by a receiving member, and attaches a cam retainer to the rear of the main electric motor. The oscillating motor is fixed to the cam retainer, and the output shaft of the oscillating motor is provided horizontally in the central direction of the main motor, and an eccentric cam is attached to the output shaft of the oscillating motor. A slide cam for sandwiching the action surface is provided, and the slide cam is sandwiched between the rear end surface of the main motor and the cam retainer, and reciprocates in one direction by the rotation of the eccentric cam, and the slide cam and the receiving cam. It has a structure in which a swing rod rotatably connected at both ends to a hardware is provided.

Action In the above configuration, the output shaft of the swinging electric motor is fixed to the rear of the main electric motor in the central direction of the main electric motor and horizontally fixed, and a slide cam for sandwiching the action surface of the eccentric cam to which the output shaft is attached is provided. By reciprocating the slide cam in one direction between the rear end surface of the main electric motor and the cam retainer, the rearward projecting dimension of the main electric motor is determined by the bending height of the cam retainer and the thickness of the swinging electric motor. Since the size is just added and the protruding range is also within the rear range of the main motor, the swing motor and the swing mechanism can be stored in the space behind the main motor in a small space.

Example An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view of a swinging device for a fan according to an embodiment of the present invention, and FIG. 2 is a rear view of a main part of the swinging device for a fan according to the same embodiment. The main motor 1, the frame 2 and the receiving object 3 have the same structure as the conventional example.

In FIG. 1 and FIG. 2, a swinging electric motor 4 is attached to the rear of the main electric motor 1 so that its output shaft is oriented toward the center of the main electric motor 1 and horizontally, and is mounted on a cam retainer 10. The presser foot 10 is fixed to the electric motor 1. An eccentric cam 11 is fixed to the output shaft of the swinging electric motor 4, and a slide cam 12 vertically slides between a rear end surface 1a of the main electric motor 1 and a cam retainer 10 by sandwiching an action surface 11a of the eccentric cam 11. It is movably supported in a floating manner. Guide pin 14 is slide cam 12
Is regulated so that it slides only in the vertical direction. The slide cam 12 and the receiving object 3 are connected by a swing rod 13 in such a manner that their joint points are rotatable.

The operation of the swinging device for the electric fan of the present embodiment configured as described above will be described below.

First, an eccentric cam attached to the output shaft of the swinging motor 4.
When 11 rotates, the slide cam 12 reciprocates in the direction regulated by the guide pin 14, that is, in the up-down direction by being sandwiched between the rear end surface 1a of the electric motor 1 and the cam retainer 10. The swing rod 13 reciprocates in a fan shape around the shaft 3a of the receiving object 3 according to the vertical movement of the slide cam 12.

The oscillating motor 4 and the traction motor 1 are formed substantially integrally, and the traction motor 1 is supported by the elevation shaft 2a of the frame 2 so that it can be elevated and lowered with respect to the receiving object 3, so that the oscillating rod 13 has a fan shape. Performs a swing motion in the elevation direction by reciprocating motion.

As described above, according to the present embodiment, the swinging electric motor having a small thickness is fixed to the rear of the main electric motor and the output shaft thereof is oriented in the central direction of the main electric motor and horizontally. The rearward projecting dimension of the electric motor is reduced, and a swing mechanism such as a slide cam can be housed so as not to project around the rear of the main electric motor.

Also, attach an eccentric cam to the output shaft of the swing motor,
Since the slide cam for sandwiching the working surface of the eccentric cam is provided, the output shaft and the eccentric cam can be housed within the thickness dimension of the slide cam to reduce the thickness dimension of the connected parts. Since it is sandwiched between the rear end surface of the motor and the cam retainer and reciprocates in only one direction, there is no wasted space before and after the slide cam, and the thickness dimension of the swing mechanism part is combined with the dimension compression of the parts to be connected as described above. Can be shortened.

Therefore, since the swing motor and swing mechanism can be installed in a small space, the amount of rear protrusion of the main motor can be reduced, the interior can be made thinner, and the front and rear length of the fan motor portion can be shortened. Since it becomes harder, the number of packaging people can be reduced.

In the present embodiment, the swinging direction is the elevation direction, but the sliding direction of the slide cam may be left and right, and the swinging direction may be the left and right direction.

According to the present invention, a cam retainer is attached to the rear of a main electric motor, a swinging electric motor is fixed to the cam retainer, and the output shaft is oriented horizontally toward the center of the main electric motor. An eccentric cam is attached to the output shaft of the vibration electric motor, and a slide cam for sandwiching the working surface of the eccentric cam is provided. The slide cam is sandwiched between the rear end surface of the main electric motor and the cam retainer, and Since the reciprocating motion is performed in one direction by the rotation, the size of the storage portion of the swing mechanism of the swing motor can be shortened, so that the amount of rear protrusion of the main motor can be reduced and the thickness can be reduced. As a result, it is possible to realize an excellent fan swinging device that improves the appearance as an interior and reduces the number of packing talents.
