[Conventional technology]

Conventionally, as this device, as described in JP-A-59-68597, helical blades are arranged in a cylindrical stand, and the air flowing from the lower surface of the cylindrical stand is transferred to the cylindrical stand. It has been known for its structure that blows out from the entire circumference of the stand.

[Problems to be solved by the invention]

The above-mentioned conventional apparatus has a drawback that air is always blown from the entire circumference of the cylindrical stand and air cannot be sent only within a predetermined angle range. Also, in order to blow air from the entire circumference of the cylindrical stand,
It has the disadvantage that the fan needs to have a special spiral shape.

An object of the present invention is to send air (wind) only to a predetermined angle range without using a special spiral fan,
Another object is to provide a blower that can send air (wind) to the entire range of 360 degrees.

[Means for solving the problem]

The present invention is characterized in that a pedestal, a main body rotatably mounted on the pedestal, an air inlet provided on a peripheral surface of the main body, an air blowing port provided on a peripheral surface of the main body, And a fan motor that rotates the fan and a fan that causes air to flow into the main body from the air suction port and flows out of the main body from the air blowing port, and the main body to the pedestal. An automatic oscillating means including a oscillating motor disposed between the main body and the pedestal for rotating the main body and the pedestal forward and backward within a predetermined rotation angle range; and A blower comprising: automatic rotation means provided with a rotation motor disposed between the main body and the pedestal for rotating by at least ° C; and a slip ring power supply means provided on the pedestal for supplying power to each motor. In the device .

[Action]

When only the fan is rotated, the air flowing out of the air blowing port is sent within a predetermined angle range and in a certain direction.

When the main body is rotated 360 degrees with respect to the pedestal while rotating the fan, the air blow port rotates 360 degrees, so that the air (wind) is sent over the entire range of 360 degrees.

When the main body is rotated forward and reverse with respect to the pedestal within a predetermined rotation angle while rotating the fan, air (wind) is sent within a predetermined angle range.

While rotating the fan, the main body is rotated by 360 degrees or more by the automatic rotation means, and the main body is rotated forward and reverse within a predetermined rotation angle range by the automatic oscillating means. When the direction in which the main body is rotated by the means coincides, the main body rotates strongly (fast), and the direction in which the main body is rotated by the automatic rotation means does not coincide with the direction in which the main body is rotated by the automatic oscillating means. In this case, the main body rotates weakly (slowly), the main body stops rotating, or the main body rotates reversely, indicating a rich air (wind) flow. Can be

The electrical connection with 58 is as shown in FIG.

The function selection button 18 changes the number of rotations of the fan driving motor 10 by changing the number of rotations of the fan driving motor 10 to a first button for selecting the operation time of the fan driving motor 10 from 30 minutes, 1 hour, 2 hours and 4 hours. A second button capable of selecting three types of light wind, a weak wind and a strong wind, a third button for rotating a main body including the front frame 1 and the rear frame 23 with respect to the base 48, and a second button capable of selecting a rhythm style. It has a fourth button and a fifth button for turning off all electric components electrically connected to the power cord 100.

By operating the third button, an automatic swing operation in which only the first small synchronous motor 38 is rotated to swing the main body at a rotation angle of 70 degrees, and a case in which only the second small synchronous motor 44 is rotated to rotate the main body. Automatic operation that rotates 360 degrees or more, the first
An automatic intermittent operation in which the small synchronous motor 38 and the second small synchronous motor 44 are simultaneously rotated to rotate the main body intermittently by 360 degrees or more can be selected.

In this embodiment, the maximum diameter of the pedestal 48 is 210φ, and
The outer diameter of the main body composed of the front frame body 1 and the rear frame body 23 is set to 165φ, and the height from the upper surface of the main body to the bottom surface of the pedestal 48 is set to about 600 mm. .

As the automatic intermittent operation selected by the third button, various modes such as strong rotation-stop-strong rotation, strong rotation-weak rotation-strong rotation, strong forward rotation-strong reverse rotation-strong forward rotation can be considered.
These modes can be realized by changing the rotation speed of the first small synchronous motor 38 and the second small synchronous motor 44.

The automatic rotation operation selected by the third button employs a method in which the main body is continuously rotated in one direction only in this embodiment. However, a timer function is incorporated, and if the main body is continuously rotated in one direction for a predetermined time, the automatic rotation operation is performed. For example, a method of stopping the rotation or a method of rotating the main body 360 degrees forward and then rotating the main body 360 degrees reversely may be adopted.

In the above configuration, when the blower of the present embodiment is placed on a desk and the wind is to be blown all around, the third button of the function selection button 18 is operated to rotate the second small synchronous motor 44. The first gear 45 rotates around the second gear 47, and the motor case 43, the support plate 33A, and the main body rotate 360 degrees together with the first gear 45.

Next, in order to send the wind only to a predetermined range, the third button of the function selection button 18 is operated to rotate the first small synchronous motor 38, and the crank 39, the swing rod 35, etc. The support plate 33A and the main body fixed to the support plate 33A swing.

Next, when sending wind to the entire circumference, if you want to change the wind, operate the third button of the function selection button 18 to
If the first small synchronous motor 38 and the second small synchronous motor 44 are simultaneously rotated, the direction in which the main body is rotated by the first small synchronous motor 38 and the direction in which the main body is rotated by the second small synchronous motor 44 match. When the main body rotates strongly (fast) and the direction in which the main body is rotated by the first small synchronous motor 38 and the direction in which the main body is rotated by the second small synchronous motor 44 do not match, the main body is weak. One of the states of (slow) rotation, stop of the main body, and reverse rotation of the main body can be obtained, so that the air volume or the like given to the user changes.

Next, when the wind from the air blowing port 5 is sent only in a certain direction without rotating the main body at all, when the sending direction is desired to be changed, the main body is lifted and the direction of the main body is not changed. When the body is strongly rotated in the circumferential direction by hand, the pin 50 descends against the elastic force of the coil spring 49, and the locked state between the second gear 47 and the pedestal 48 is released. It can be directed in the direction desired by the user. In this state, if the rib 2 or the variable wing 4 is rotated, the flow direction of the air in the air blow port 5 can be changed.

When the blower of the present embodiment is used as a fan, the fan 6 is rotated in a state where the second filter 25 is moved in a direction away from the air suction port 28,
The air that has flowed into the air suction port 28 through the first filter 27 is caused to flow out of the main body through the air blowing port 5.

When the blower of the present embodiment is used as an air purifier, the first filter is rotated by rotating the fan 6 in a state where the second filter 25 is moved so as to completely cover the outer surface side of the air suction port 28. The air filtered by the filter 27 and the second filter 25 is caused to flow into the main body through the air suction port 28 and flow out of the main body through the air blowing port 5.

When increasing or decreasing the air purifying function of the air blower of the present embodiment, the second filter 25 is moved so that the outer surface of the air suction port 28 has a portion covered by the second filter 25 and a portion not covered. State. In other words, the amount of air flowing into the air suction port 28 only through the first filter 27 and the amount of air flowing into the air suction port 28 through both the first filter 27 and the second filter 25 are different. By changing the ratio, the air cleaning ability can be adjusted.

When the neon tube 58 is turned on, the lower end flange portion 60 of the reflector 59 shines like an edge light and the uneven portion 48 of the pedestal 48.
C gives you a subtle reflection of light,
Can produce fluorescent images.
