DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as examples. 1 is a cross-sectional view of an air purifier according to the present invention (and a conventional example), FIG. 2 is an explanatory view of an air purifier according to the present invention, (A) is a plan view of a main part, and (B) is a cross-sectional view of a main part. FIG. 3 is an explanatory view of a main part of an air purifier according to the present invention. FIG. 3 (A) is a sectional view showing a first example, FIG. 3 (B) is a sectional view showing a second example, and FIG. Sectional drawing which shows an example, (D) is sectional drawing which shows a 4th example.

An air purifier having a swing function according to the present invention, as shown in the drawing, has a stand 1 configured such that its bottom surface is opened and can be freely opened and closed by a bottom cover 1a.
And a lower part of a main body case 4 having a suction port 2 on a front surface and a discharge port 3 on an upper surface, and a drive motor 5 provided inside the stand 1 is linked to be provided at an upper part of the stand 1. The base 6 is supported by the support plate a provided so as to be swingable in the horizontal direction via a plurality of rollers b.

An air passage connecting the suction port 2 and the discharge port 3 is provided with an air cleaning filter 7 and a blower including a blower fan 8 and a fan motor 9.

A power cord 10 connected to the drive motor 5 and the fan motor 9 is provided from the stand 1
It is to be introduced into the main body case 4 which is swingably supported by the support plate a.

An introduction section 11 for introducing the power cord 10 from the stand 1 into the main body case 4 is shown in FIG.
As shown in FIG. 2B and FIG. 2B, the center of the stand 1 and the support plate a
Thus, a configuration is provided in which the center position of the base 6 that is swingably supported via the plurality of rollers b is communicated.

As a result, when the base 6 is swung, the introduction portion 11 does not move from the center position of the stand 1 and the base 6, as in the above-described problem in the prior art. However, the power cord 10 is rubbed and damaged by the periphery of the introduction portion 11, is twisted, the length is difficult to adjust, and a large torque is required to swing the base 6. You don't have to.

Further, by forming the opening of the introduction portion 11 in an arc shape, the power cord 10 has a structure further enhanced in safety so as not to be damaged.

Here, the first to fourth embodiments of the introduction section 11 will be sequentially described with reference to FIGS. 3A to 3D.

As shown in FIG. 3A as a first embodiment, the introduction portion 11 is provided at a center position of the base 6 and has a cylindrical shape provided with a center hole 12 through which the power cord 10 is inserted. It comprises a rotating shaft 13 and a support hole 1b provided on a support plate a above the stand 1 and provided with a flange 14 for rotatably supporting the tip of the rotating shaft 13.

The provision of the flange 14 enhances the strength of the support hole 1b and allows the tip of the rotating shaft 13 to be smoothly supported.

As a result, the power cord 10 remains inserted through the center hole 12, and the base 6 forming the lower part of the main body case 4 swings regardless of whether or not it swings. Is accurately and safely protected without moving the position.

As shown in FIG. 3B as a second embodiment, a locking portion 15 is provided on the flange 14, and the locking portion 15 is provided.
In addition, the power supply cord 10 is inserted and the insertion tube 16 is inserted into the center hole 12 in a state where the bushing 18 provided with the locking claw 17 corresponding to the locking portion 15 is locked. I have.

Thus, even when the base 6 forming the lower part of the main body case 4 is swung, the bushing 18 is locked by the support plate a provided on the upper part of the stand 1. Therefore, since the power cord 10 does not swing together, the power cord 10 is not rubbed by the bushing 18, so that the power cord 10 is protected more accurately and safely.

As a third embodiment, as shown in FIG. 3C, a supporter for detachably supporting a clamper 19 for clamping the power cord 10 is provided on the bottom cover 1a facing the center hole 12. It is configured with 20 standing.

As a result, the power cord 10 is inserted into the center hole 12 after being clamped at the lower portion of the center hole 12, so that the power cord 10 is no longer damaged and the base 6 can be removed. You can swing without resistance.

Further, as shown in FIG. 3D as a fourth embodiment, the introduction portion 11 is provided at a rotation hole 21 provided at a center position of the base 6 and at an upper portion of the stand 1. The power cord is provided at a center position of the support plate a.
A cylindrical support shaft 22 is inserted through the support hole 10 to rotatably support the rotary hole 21. A flange 23 along the support shaft 22 hangs down the periphery of the rotary hole 21.

This allows the power cord 10 to pass through the support shaft 22 provided on the support plate a, which is not swinging, on the stand 1 side.
The bushing is no longer rubbed at 22 and compared to the case of the second embodiment described above with reference to FIG.
Accurate and safe protection is achieved by a simple configuration without using 18.

The provision of the flange 23 enhances the strength of the rotary hole 21 and allows the distal end of the support shaft 22 to be smoothly supported.
