Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air blower, and particularly to an air blower suitable for use by being installed on a tabletop.

[Conventional technology]

Conventionally, as described in Japanese Patent Application Laid-Open No. 59-68597, a spiral blade is disposed inside a cylindrical stand, and air flowing from the bottom of the cylindrical stand is directed into the cylinder. It was known for its configuration in which air was blown out from around the entire circumference of the stand.

[Problem to be solved by the invention]

The conventional device described above has the disadvantage that air is always blown out from the entire circumference of the cylindrical stand, and air cannot be sent only within a predetermined angular range. Another drawback is that the fan needs to have a special spiral shape in order to blow air out from the entire circumference of the cylindrical stand.

The object of the present invention is to be able to send air (wind) only to a predetermined angular range or to send air (wind) to the entire 360 degree range without using a special spiral fan. To provide air blowing equipment.

[Means to solve the problem]

The above object includes a pedestal, a main body rotatably attached to the pedestal, an air suction port provided on the main body, an air blowing port provided on the main body, and a main body disposed within the main body, and A fan that causes air flowing into the main body from the air suction port to flow out of the main body from the air blowing port, a motor that rotates the fan, and an automatic rotation that rotates the main body by 360 degrees or more with respect to the pedestal. This is achieved by an air blowing device comprising a means for rotating the main body forward and backward within a predetermined rotational angle range with respect to the base.

[Effect]

When only the fan is rotated, the air flowing out from the air outlet is sent within a predetermined angle range and in a fixed direction.

If the main unit is rotated 360 degrees with respect to the base while rotating the fan, the air outlet will rotate 360 degrees, so air (wind) will be sent over the entire 360 degree range.

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

While rotating the fan, the automatic rotation means rotates the main body 360 degrees or more, and the automatic swing means rotates the main body forward and backward within a predetermined rotation angle range. One main body rotates strongly (fast) when the direction in which the main body is rotated by the means matches, and the direction in which the main body is rotated by the automatic rotation means and the direction in which the main body is rotated by the automatic swinging means do not match. If the body is weak (
The main body rotates slowly), the main body stops rotating, or the main body rotates in the opposite direction, and the flow of air (wind) is changed in a variety of ways.

Next, if you want to change the line when blowing air around the entire circumference, operate the third button of the function selection button 18 to simultaneously rotate the first small synchronous motor 38 and the second small synchronous motor 44. Then, when 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, the first main body rotates strongly (fastly), and the first main body rotates strongly (fastly). Small synchronous motor 3
When the direction in which the main body is rotated by the motor 8 and the direction in which the main body is rotated by the second small synchronous motor 44 do not match, the main body rotates weakly (slowly), the main body stops, or the main body rotates in the opposite direction. Since either state can be changed, the amount of air given to the user changes.

Next, if you want to send the air from the air outlet 5 only in a certain direction without rotating the main body at all, and you want to change the sending direction, you can do so without having to lift the main body and change the direction of the main body. When the main 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 second gear 47
Since the locking state between the and the pedestal 48 is released, the air outlet 5
It can be directed in the direction desired by the user. In this system, by rotating the ribs 2 or the variable blades 4, the flow direction of the air at the air outlet 5 can be changed.

When the blower device of this embodiment is used as an electric fan, by rotating the fan 6 with the second filter 25 moved in a direction away from the air suction port 28, the air passes through the first filter 27 and enters the air suction port 28. The air that has flowed into the body is made to flow out of the main body from the air blowing port 5.

When the blower device of this embodiment is used as an air cleaner, the first filter is removed by rotating the fan 6 while moving the second filter 25 so as to completely cover the outer surface of the air suction port 28. 27 and second filter 2
5 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 blower of this embodiment, move the second filter 25 so that the outer surface of the air suction port 28 is covered with some parts and parts not covered with the second filter 25. state. In other words, the air inlet 2 passes only through the first filter 27.
8, the amount of air flowing into the first filter 27 and the second filter
By changing the ratio of the amount of air flowing into the air intake port 28 through both filters 25, the air cleaning capacity can be adjusted.

When the neon tube 58 is turned on, the lower end flange part 60 of the reflector 59 shines like an edge light, and the uneven part 48C of the pedestal 48 produces a faint light reflection effect, so that a large-scale image can be produced.
