Abstract

PURPOSE:To make the shape of a package small, enable installation close to a wall surface, and reduce a housing space by fixing an oscillating motor in a case positioned in a place other than the rear of a vane motor and eliminating the rearward projection of a head part having said vane motor. CONSTITUTION:An oscillating motor 22 is fixed in a case 14 with a screw 24 and via a supporting plate 23, in a place other than the rear part of a vane motor 5. And, the lower part of an L-shaped supporting body 7 which is oscillated by the oscillating motor 22, is supported by a lower member 13, while the vane motor 5 is supported by its upper part. Thus, since the oscillating motor 22 is provided in a place other than the rear part of the vane motor 22, a head part 6 having the vane motor 5 will not be projected out 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.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a support structure VC for a blade motor in a single fan, t#.
It is related to

[Conventional technology]

FIG. 7 is a longitudinal sectional view of the head of a fan disclosed in, for example, Japanese Patent Publication No. 57-34477.

In the figure, (61) is a head cover composed of a front cover (61a) and a rear cover (61b), (62)
is a blade electric motor housed inside the head cover (61).
The vanes (not shown) are connected to and stacked on the shaft (62a).

Nubindle (65) is fixed to the blade electric motor (62) and supported on a column (not shown) via an intervening net (not shown) below; (64) is the blade electric motor (62); base fixed to the rear and rear cover (61b).

Reference numeral (65) denotes a neck accelerator fixed to the base plate (64), the shaft (65a) of which protrudes downward. (66) is a crank fixed to the shaft (65a), (6C is a swinging rod pivotally supported by the crank).

One conventional electric fan is configured like an upper dpi, and a oscillating type TM machine (65) is arranged at the rear of a nine-blade electric motor (62).

The rotation is transmitted to the shaft (6"A), the crank (66), and the swinging rod (6") to form a well-known swinging mechanism.

[The problem that the invention attempts to solve 1] In the conventional electric fan like the one mentioned above, the one-blade fan is oscillating (62).
Since the neck-mounted '(iTc! I machine (65)) is placed at the rear of the aircraft, the head of the Koro 1 fighter is shaped to protrude backwards.

It is inevitable that the packaging shape is too large. Close to wall
cannot be installed. Take up space for storage. There are other problems.

This invention was made to solve the above problems, and the head does not protrude backwards, 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 is to provide electric fans.

[Means for solving problems]

The electric fan according to the present invention is provided with a swinging motor at a location other than the rear part of the two-blade electric motor, and an L-shaped support that swings by the swinging motor.

The lower part of this support body is supported by a lower member, and the blade movable machine is supported by the upper part.

[Effect]

In this invention, since the oscillating motor is provided at a location other than the rear of the two-blade motor, the nine heads do not protrude rearward.

U is a shaft cylinder O9 that is fitted into the case 64 and pivotally supports the spindle a3.

The E II song ■, which is inserted into the tip of the O3 and restricts the upward movement of the spindle θ2, is inserted into the spindle α and is connected to the spindle through the clutch stand CIl+ by a mechanical force, and the arm (A) is the support. The oscillating motor is fixed in the case a4 with a screw @ through the plate (c), and the O5 is the bottle (
A crank (G) is fixed to the shaft of the electric motor for oscillation; one end of the rod is pivotally attached to the tip of the crank (C) via a washer (■) with a screw, and the other end is pivotally attached to the tip of the arm (■). , 31 is a time switch, OD is a knob for setting up the turn, and α2. Turns a to (to) are stored in the control box aJ. And one head (6) and the above (71~O1

In the electric fan configured as described above, when power is supplied to the 0-blade electric motor (5), the 9 blades (41) are rotated and air is blown through the front guard.

On the other hand, when power is supplied to the oscillating motor.

The crank (c) rotates and causes the rod @ to reciprocate.

This movement is transmitted to the arm ■. As a result, the arm (2) swings around its axis, and the support body (71

) is covered.

In other words, the operation of the 1-head shaker is almost the same as that described above, and the 9-head shaker'f! The rotation of the L motor causes the crank (G).
rotates [1. As the rod @ reciprocates, the support body (71) swings around the spindle H. In this way, it is possible to obtain the same function as in the previously described embodiments.

〔Effect of the invention〕

As explained above, in this invention, a swinging motor is provided at a location other than the rear of the single-blade motor. An L-shaped support body is provided which is movably moved, and the lower part of this support body is supported by a lower member.

Since the blade electric motor is supported on the upper part, the two heads do not protrude backwards, and the package shape can be made smaller, and it can be installed close to a wall and can be stored in a narrow space.
