Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an improvement of a blower mounted on a wall, a so-called wall fan.

(b) Prior art As a technology prior to the present invention, there is Japanese Utility Model Application Publication No. 53-58860. The electric fan described in this publication has a rear guard made of plastic that is divided into front and rear parts, a motor mounting part is integrally formed in the center of the rear guard, and the motor and fan attached to this part are placed inside the guard. In addition to storing the rear guard, a recess is formed at the lower end of the rear guard and a neck piece is inserted into the recess. Therefore, although the direction of the blower can be changed manually, it does not swing automatically, and there is no means to swing the blower horizontally, so it is not possible to change the air flow in the left-right direction. Ta.

In addition, there is a fan described in Japanese Patent Publication No. 57-36435 that uses an oscillating motor device to change the direction of air blowing, but the prior art engineer housed the oscillating motor device in the rear part of the fan head. , the head of the electric fan becomes larger.

(c) Problems to be solved by the invention The purpose of this invention is to provide a blower that is made thin and can automatically change the blowing direction.

(d) Means for Solving the Problems The blower of the present invention includes a stand that is attached to a wall, a neck piece whose lower end is pivoted to the stand so that the angle of elevation can be adjusted, and a neck piece that is pivoted to the neck piece so that it can swing freely. a guard body having a motor mounting portion formed in its center; a blower blade attached to a motor fixed to the motor mounting portion of the guard body; a blower body attached to a front surface of the guard body; an oscillating motor device for oscillating the guard body, a mounting portion of the oscillating motor device being formed at a lower rear part of the guard body, and an output shaft of the oscillating motor device and a neck piece for oscillating the neck piece. It is characterized by being connected by a link.

(E) Effect With the above configuration, the main body of the blower can be made thinner by attaching the swing motor device that swings the guard body to the lower rear part of the guard body, and the protruding parts of the entire blower can be reduced to achieve a thinner profile. Can be done.

(F) Embodiment The blower 1 includes a stand 2 that is mounted on a wall W and has a switch, etc. installed therein, and a neck piece 3 that is pivoted to the two prongs at the end of the stand 2 so as to be able to adjust the angle of elevation and elevation.
and a blower main body 4 which is pivotably supported on the neck piece 3. The stand 2 is molded from synthetic resin, and its opening is closed with a back plate made of sheet metal. The neck piece 3 is attached to the stand 2
It is held at an appropriate rotational operation position while being pivotally supported by, and its structure uses a conventionally known elevation angle adjustment device. A shaft support hole extending vertically is formed in the neck piece 3, and a bearing body 6 having a flange 5 formed thereon that covers the upper surface of the neck piece 3 is inserted into the shaft support hole. The bearing body 6 can rotate and is held at an appropriate rotational position by a locking body 7 consisting of a spring and a locking body. A pivot pin 8 is provided protruding from the upper peripheral edge of the flange 5.

The blower main body 4 has a guard body 9 made of synthetic resin.
and a motor 12 fixed with a screw 11 to a motor mounting portion 10 formed in the center of the guard body 9.
, a blower blade 13 attached to the rotating shaft of the electric motor 12 , a pivot shaft 15 fixed to the lower front part of the guard body 9 with a screw 14 , and a pivot shaft body 15 formed at the lower rear part of the guard body 9 . The swing motor device 18 is fixed to the mounting portion 16 with a screw 17, and the blower body 19 is attached to the front surface of the guard body 9. The pivot shaft body 15 includes a shaft portion 15a that is inserted into and pivotally supported by the bearing body 6, and a mounting plate portion 15b that is fixed to the upper end portion of the shaft portion 15a. The mounting plate portion 15b is formed of a sheet metal and is located close to the tip of the pivot pin 8 of the collar portion 5. The guard body 9 includes a ring portion 9a surrounding the blower blade 13, and the ring portion 9a.
A guard portion 9b formed in a dome shape on the rear edge of the
The motor mounting part 10 is formed in the center of the guard part 9b and opens toward the front; the mounting part 16 is formed in the lower part of the guard part 9b so as to open downward; and the front edge of the ring part 9a. the mounting portion 9c of the blower body 19 formed in the ring portion 9;
It consists of a fixing part 9d of the pivot shaft body 15 formed on the outside of the lower part of a. A groove 20 that opens on the inner surface of the guard body 9 is formed in the crosspiece of the guard part 9b that extends downward from the motor mounting part 10, reaches the mounting part 16, and extends to the lower rear edge of the ring part 9a. There is. An electric cord 21 to the electric motor 12 and the oscillating motor device 18 is wired to the groove portion 20 . The oscillating motor device 1 is attached to the mounting portion 16.
8, its output shaft protrudes downward. A cam body 22 is attached to the output shaft, and the cam body 22
One end of the swing link 23 is pivotally supported. The other end of the swing link 23 is pivotally supported by the pivot pin 8.
The mounting portion 16 and the swing link 23 are covered with a cover 24.

When the oscillating motor device 18 is operated, the blower main body 4 oscillates from side to side about the shaft portion 15a.

Although the blower body 19 is formed of a guard body having a large number of crosspieces and having low blowing resistance, the blower body 19 is not particularly limited thereto. For example, the blowing body may be a wind direction changing body rotationally driven by wind pressure or a motor, or a large number of wind direction changing plates may be arranged vertically or horizontally so that the blowing direction can be changed manually or automatically. You may also do so.

Further, the electric motor 12 may be attached to the guard body 9 from the outside in a mounting portion opened to the outside, and the rear surface may be covered with a cover. Furthermore, the oscillating motor device 18 may be attached to the guard body 9 such that the output shaft protrudes from inside the guard body.
Although the embodiment is a wall-mounted blower, the stand may be of a floor-standing type.

(f) Effects of the invention This invention supports the lower part of the guard body so that it can swing freely, and by installing electric motors and swing motor devices vertically in the center and lower rear parts of the guard body, the amount of front and rear protrusion can be reduced. By making it smaller, it can be made thinner, and the wind direction can be changed smoothly from side to side. In addition, since the swing motor device is located at the bottom rear of the guard body,
Even when the guard body is facing down, the center of gravity can be well balanced, and the durability of the neck piece can be improved.
