The suction unit 5 is formed in a duct form provided with a suction port 5a at an end adjacent to the floor of the indoor space, and the flow path associated with the suction unit 5 is not shown but through a conventional pipe or hose. It is connected to the air inlet 11 (see FIGS. 2 and 3) of the cyclone device 10 to be described later to allow the air and foreign matter to be guided toward the air inlet 11.

Although not specifically shown in the drawing, the blowing unit 4 is composed of a blowing fan for generating a suction force and a motor for driving the blowing fan. The blower unit 4 is connected to a discharge guide tube 13 extending downward from the air outlet 12 (see FIGS. 2 and 3) of the cyclone apparatus 10. Therefore, the clean air filtered out of the foreign matter while passing through the cyclone device 10 is sucked toward the blower unit 4 through the discharge guide tube 13 to be discharged back to the indoor space.

The cyclone apparatus 10 installed at the upper portion of the blowing unit 4 is detachably mounted to the body 1 by a binding device (not shown), and the structure of the cyclone apparatus 10 is shown in FIGS. 2 to 4. Reference will be made in detail below.

As shown in FIG. 2 and FIG. 3, the cyclone apparatus 10 according to the exemplary embodiment of the present invention has an outer container 21 formed in a substantially cylindrical shape and an inner container 22 disposed inside the outer container 21. It is installed in the main body 20 and the inner container 22 including the primary cyclone 30 and the outer container 21 to filter out large dust and foreign matter contained in the suction air primary primary cyclone ( And a secondary cyclone 40 to secondaryly filter small dust and the like contained in the air discharged from 30).

The outer container 21 and the inner container 22 are separated from each other by the upper plate 23 covering the upper portion thereof, while the plurality of communication holes 24 arranged at regular intervals to form concentric circles on the upper plate 23. Is communicated by.

The air inlet 11 of the cyclone device 10 is provided on the side of the main body 20 to communicate with the primary cyclone 30, the air outlet 12 of the cyclone device 10 is located on the upper portion of the main body 20 It is provided to communicate with the secondary cyclone (40).

The primary cyclone 30 is installed at the upper center of the inner container 33 and is provided at the lower portion of the primary cyclone chamber 31 and the inner container 33 having a substantially cylindrical shape. And a first collecting part 32 which collects dust and foreign matter which are separated from each other.

The secondary cyclone 40 is provided in the lower portion of the plurality of second cyclone chamber 41 and the outer container 21 having the same shape and size disposed along the circumferential direction from the upper portion of the outer container 21. A plurality of guides for guiding air passing through the second collecting portion 42 and the primary cyclone chamber 31 to collect dust and foreign matter secondary separated by the first to each secondary cyclone chamber 41 A guide member 43 is provided.

In addition, the main body 20 can be separated into an upper portion and a lower portion by a connection portion 25 provided at an intermediate point thereof so as to empty dust and foreign matter accumulated in the first and second collection portions 32 and 42.

The air inlet 11 is disposed above the main body 20 to communicate with the primary cyclone 30 and a plurality of through-holes 33 are formed on the circumferential surface of the primary cyclone chamber 31 with the upper portion open. Air flowing into the primary cyclone 30 through the inlet 11 is pivoted between the outer circumferential surface of the primary cyclone chamber 31 and the inner circumferential surface of the inner container 33 while the dust and foreign matter contained in the air are moved by centrifugal force. Separated and accumulated in the first collecting portion 32 and the primary filtered by the primary cyclone 30 is introduced into the interior of the primary cyclone chamber 31 through a plurality of through-holes 33 to move upwards. .

The plurality of secondary cyclone chambers 41 have a conical shape in which the cross-sectional area decreases from the top to the bottom thereof, and the secondary cyclone chamber 41 is formed in the upper center of the secondary cyclone chamber 41 through the guide member 43. An outlet 41a is formed to allow the introduced air to escape.

The guide member 43 is positioned in the communication hole 24 of the upper plate 23 so as to guide the air that has passed through the primary cyclone chamber 31 to the secondary cyclone chamber 41, and thus the primary cyclone chamber 31. It has an inlet 44 in communication with the outlet 45 and the outlet 45 in communication with the secondary cyclone chamber 41 is formed in a substantially spiral shape.

The outlet portion 45 is disposed along the inner circumferential surface of the secondary cyclone chamber 41 so that air flowing along the helical guide member 43 is guided to the inner circumferential surface of the secondary cyclone chamber 41 so that the secondary cyclone chamber 41 In this case, turn air is generated.

The dust and foreign matter contained in the air that pivots downward along the inner circumferential surface of the secondary cyclone chamber 41 fall downward and accumulate in the second collecting part 42, and the secondary filtered air moves upward to the secondary cyclone. It is discharged through the discharge port 41a of the 40.

Fine dust in the air from which dust and foreign substances are removed to some extent through the primary and secondary cyclones 30 and 40 between the outlet 41a of the secondary cyclone 40 and the air outlet 12 of the cyclone apparatus 10. The filter 50 for finally filtering is provided.

In order to fix the filter 50, a filter grill 51 is provided between the outlet 41a and the outlet 12. The filter grill 51 is crossed with each other to support the fixing unit 52 for fixing the filter and the filter 50 which is upwardly driven by the air discharged from the outlet 41a of the secondary cyclone 40. A plurality of ribs 53 are provided. As the plurality of ribs 53 cross each other to form the plurality of openings 54, air discharged from the outlet 41a of the secondary cyclone 40 can escape to the air outlet 12.

Each rib 53 of the filter grill 51 does not act as a resistor of the air discharged through the outlet 41a of the secondary cyclone 40. It is disposed radially so as to pass between the secondary cyclone 40 outlet 41a passing through the center and neighboring each other.

As such, the openings 54 between the ribs 53 are formed to correspond to the positions of the outlets 41a of the plurality of secondary cyclones 40, so that the ribs 53 of the filter grill 51 are secondary cyclones ( It does not act as a resistor of the air discharged through the discharge port 41a of 40). Therefore, the air discharged through the outlet 41a of the secondary cyclone 40 may hit the rib 53 of the filter grill 51 to reduce noise.

In the above embodiment, the rib 53 is radially disposed to form the opening 54 of the filter grill 51 so as to correspond to the position of the outlet 41a of the secondary cyclone 40, but the rib is necessarily radial. It does not need to be arranged, and it is natural to fall within the scope of the present invention as long as the openings are formed between the ribs so as to correspond to the positions of the outlets of the plurality of secondary cyclones. Accordingly, those skilled in the art to which the present invention pertains, as well as the above embodiments, may implement embodiments of other forms within the scope equivalent to the technical idea of the present invention only by the description according to the embodiment of the present invention. It should be understood that the present invention should not be construed as being limited to the above embodiments.

As described above in detail, according to the present invention, an opening of the filter grill is formed to fix the filter to correspond to the position of the outlet of the secondary cyclone, and the rib of the filter grill is a resistor of air discharged through the outlet of the secondary cyclone. Since this does not work, it is possible to reduce the noise generated by the cyclone device.
