[Problems to be Solved by the Invention] In the above-described conventional technology, it is necessary to attach or remove a filter to or from the air suction port each time to switch between the air cleaner and the fan, which is unsanitary. Also, it is inconvenient.

An object of the present invention is to provide a sanitary and convenient blower device that can be easily switched between an air cleaner and a fan without installing or removing a filter one by one.

[Means for Solving the Problems] The purpose is to provide a pedestal, a main body attached to the pedestal, and
The air suction port provided in the main body, the air blowing port provided in the main body, the air provided in the main body, and the air flowing into the main body from the air suction port is supplied from the air blowing port. A fan that flows out of the main body, a motor that rotates the fan, a coarse first filter that covers the outer peripheral surface of the air suction port, and an eye that is disposed between the first filter and the air suction port. And a second filter having a fine second filter, the second filter being installed in the main body so that the amount of air flowing into the main body through both the first filter and the second filter changes substantially. This is achieved by movably providing it.

[Operation] When it is desired to use for the air purifier, the second filter should be placed so that the first filter and the second filter are completely overlapped.
Move the filter. As a result, the dust in the air is removed by the first filter and the second filter, and only clean air flows into the main body from the air suction port.

When it is desired to use the fan, the second filter is not moved so that the first filter and the second filter do not become heavy at all. As a result, the dust in the air passes through the inside of the main body from the air suction port and is discharged from the air blowing port with almost no filtration, and functions as a normal fan.

When it is desired to set the air purifying function of the user's preference, the movement of the second filter is adjusted to change the degree of overlap between the first filter and the second filter. As a result, the degree of removal of dust in the air by the fine second filter is increased or decreased, so that it is possible to set the state as desired by the user.

The function selection button 18 is a first button that can select four kinds of operation time of the fan drive motor 10, 30 minutes, 1 hour, 2 hours, and 4 hours, and the rotation speed of the fan drive motor 10 is changed. A pedestal with a main body consisting of a front frame body and a rear frame body 23, and a second button for selecting three types of light wind, weak wind and strong wind
It is equipped with a third button that rotates with respect to 48, a fourth button that can select the rhythm style, and a fifth button that puts all the electrical parts electrically connected to the power cord 100 in the "off" state. ing.

By operating the third button, only the second small synchronous motor 44 is rotated to automatically swing the main body at a rotation angle of about 70%, and only the first small synchronous motor 38 is rotated to rotate the main body. With automatic rotation operation to rotate 360 degrees or more,
It is possible to select an automatic intermittent operation in which the first small synchronous motor 38 and the second small synchronous motor 44 are simultaneously rotated to intermittently rotate the main body by 360 degrees or more.

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

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-weak 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.

In the present embodiment, the automatic rotation operation selected by the third button employs a system in which the main body is continuously rotated in only one direction, but a timer function is combined to continuously rotate the main body in one direction for a predetermined time. In that case, a method of automatically stopping the rotation or a method of rotating the 360-degree main body in the forward direction and then rotating the 360-degree main body in the reverse direction may be adopted.

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

Next, when it is desired to send the wind only within 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, and the like cause the support plate to move. The main body fixed to 33A and the support plate 33A swings.

Next, when sending the wind to the complete collection, if you want to change the wind, operate the third button of the function selection button 18,
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 (faster), 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. Either (slow) rotation, the main body stops, or the main body rotates in the reverse direction, so that the amount of air supplied to the user changes.

Next, when the air from the air blowing port 5 is sent only in a certain direction without rotating the main body at all, and when the user wants to change the sending direction, the main body is lifted and the direction of the main body is not changed. 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 locked state between the second gear 47 and the pedestal 48 is released, so that the air blower port 5 is used by the user. You can turn to the direction you want. In this state, if the ribs 2 or the variable vanes 4 are rotated, the flow direction of the air in the air blowing port 5 can be changed.

When the blower of this embodiment is used as a fan, the second filter 25 is attached to the air suction port 28 as shown in FIG.
By rotating the fan 6 while moving it in a direction away from the air, the air that has passed through the first filter 27 and into the suction port 28 is discharged from the air blower port 5 to the outside of the main body.

When the air blower of this embodiment is used as an air cleaner, the fan 6 is rotated while the second filter is moved so as to completely cover the outer surface side of the air suction port 28 as shown in FIG. By doing so, the air filtered by the first filter 27 and the second filter 25 is supplied to the air suction port.
It is made to flow in from 28 into the main body, and is made to flow out of the main body from the air blowing port 5.

When increasing or decreasing the air cleaning function of the air blower of this embodiment, the outer surface of the air suction port 28 should be covered with the second filter 25 and not covered with the second filter 25 as shown in FIG. , The second filter 25 is moved. In other words, the amount of air flowing into the air suction port 28 through only the first filter 27 and the first filter 27
By changing the ratio with the amount of air flowing into the air suction port 28 through both the 27 and the second filter 25, the air cleaning capacity can be adjusted.

When the main body is rotated in the state shown in FIG. 2, the blower of this embodiment can be used as a 360-degree rotating fan or a swinging fan.

When the main body is rotated in the state shown in FIG. 3, the air blower of this embodiment can be used as an air purifier that rotates 360 degrees or as an air purifier that swings.

When the blower of this embodiment is used as a fan, the first filter 27 may be removed from the filter holder 26 in the state shown in FIG.

As described above, according to the present invention, the air suction port is provided with the coarse first filter and the fine second filter,
Since the second filter is provided movably with respect to the main body so that the amount of air flowing into the main body through both the first filter and the second filter is changed, the second filter is used. Easy to switch between and
And it can be done hygienically. A blower with excellent usability can be obtained.
