Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cyclone type vacuum cleaner. More specifically, the present invention relates to a cyclone type upright type electric vacuum cleaner capable of improving dust collecting performance.

[0002]

2. Description of the Related Art A conventional cyclone type vacuum cleaner cannot obtain a strong swirling flow that produces a strong cyclone effect.
A mesh-shaped main filter is provided in the exhaust part before the swirl flow motor to prevent fine dust from going to the motor of the main body.

[0003]

However, as shown in FIG. 5, since the cross-sectional shape of the conventional main filter 51 is spread radially, the air flow is disturbed in front of the filter 51, and the swirling flow is generated. The flow velocity of is reduced. For this reason, the amount of dust removed by the cyclone method is reduced, and instead, the filter 51 is clogged with dust, and problems such as an overspeed state of the motor are likely to occur. Therefore, in order to extend the life of the filter 51, it is desired to generate a stronger swirling flow (high speed) by which fine dust is distributed by the cyclone effect.

In view of the above circumstances, it is an object of the present invention to provide a cyclone type upright type electric vacuum cleaner which can improve the dust collecting performance.

[0005]

The electric vacuum cleaner of the present invention comprises:
A cyclone-type vacuum cleaner comprising: a suction tool body, a cleaner body that is swingably supported with respect to the suction tool body, and a dust collecting section that is detachably attached to the cleaner body, It is characterized in that it is provided with a radial filter arranged in the dust collecting portion, and the filter is inclined.

BEST MODE FOR CARRYING OUT THE INVENTION A cyclone type vacuum cleaner according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, an electric vacuum cleaner according to an embodiment of the present invention is a dry cyclone type up apparatus composed of a suction tool body 1, a cleaner body 2 and a dust collecting portion 3. It is a light type vacuum cleaner.

The suction tool body 1 is provided with a pair of wheels 4a and 4b at front and rear portions thereof so as to be movable, and at the same time, a rotary brush (not shown) which faces an opening 5 formed on the bottom surface. No)) is built in. The rotating brush is rotated via a belt (not shown) wound around a support shaft and a rotating shaft of an electric blower (not shown) housed between the wheels 4b at the rear portion. The cleaner body 2 is swingably supported with respect to the suction tool body 1.

The dust collecting portion 3 is mounted on a main body receiving portion 6 at a front portion of the cleaner main body 1, and is detachably attached to the cleaner main body 2 by a mounting mechanism 7 with respect to the cleaner main body 2. It is installed. The dust collector 3 is used on the upper portion of the dust collector 3 when the dust collector 3 is attached to or detached from the cleaner body 2, and when the dust collector 3 is attached to the cleaner body 2. A handle 8 for carrying the dust collecting part 3 and the cleaner body 2 is formed. Further, in the dust collecting chamber 9 of the dust collecting unit 3, the prefilter 11a and the inside of the prefilter 11a are arranged in the exhaust unit 10 before the air flowing into the dust collecting chamber 9 goes to the electric blower. A cyclone type dust removing filter 11 including a radial main filter 11b such as a HEPA filter is disposed.

The dust-containing air sucked from the suction tool body 1 is connected to the suction tool body 1 by the connecting pipe 1.
2 and the hose 13 connected to the connecting pipe 12 to enter the dust collecting chamber 9 from the pipe connecting portion 14 to the dust collecting portion 3. Then, the dust-containing air that has entered the dust collection chamber 9 flows in from the tangential direction of its side surface shape so that a swirling flow is generated in the dust collection chamber 9. Then, due to the swirling flow, the dust contained in the air is separated from the air by the centrifugal force, and is pushed out to be deposited on the lower portion of the dust collection chamber 9. On the other hand, the air passes through the pre-filter 11a and the main filter 11b and is sucked into the exhaust unit 10, and in the process, fine dust is captured by the filter.

In the present embodiment, as shown in FIG. 4, the left and right portions 15 of each peak of the main filter 11b are provided.
Of the lengths (slope lengths) of a and 15b, by changing the length of the left part 15a more than the length of the right part 15b, F
It is inclined toward the swirling flow in the direction so as not to resist the flow of air. As a result, the cyclone effect can be sufficiently exerted and a strong swirling airflow can be obtained.
The inclination angle of the filter is not particularly limited, but is usually about 15 to 60 °, preferably 30 to 4
It is about 5 °.

Therefore, in the present embodiment, the swirling flow is sped up to reduce the amount of dust that goes to the main filter and prevent clogging of the main filter, so that the dust collection performance is maintained for a long time. be able to.

The vacuum cleaner according to the present embodiment is provided with a dust removing filter composed of a pre-filter and a main filter.
The present invention is not limited to this, and the present invention can be applied to an electric vacuum cleaner provided with a dust removing filter that is a radial filter without a prefilter.

[0014]

As described above, according to the present invention,
With a simple configuration that the shape of the filter is inclined so as not to resist the swirl flow, the swirl flow can be sped up, so that the filter is less likely to be clogged and the filter function maintenance time can be extended. .
