There is an effect that the separation performance is reduced.

In addition, as one or more guide ribs for guiding the flow of air is formed in the air discharge portion through which the air discharged from the cyclone unit flows, the vortex of the air in the air discharge portion is reduced, thereby minimizing air flow noise. There is this.

In addition, a plurality of bodies are combined to form a complete cyclone unit. Therefore, since the respective bodies are combined after the production of the respective bodies, the number of molds for manufacturing the respective bodies is reduced, thereby reducing the cost and easily manufacturing the cyclone unit.

In addition, as the first cyclone body is rotatably coupled to the second cyclone body, the inside of the cyclone unit and the filter member may be easily cleaned while the first cyclone body is rotated, and the filter member may be cleaned. It can be replaced easily.

In addition, the second cyclone body 120 includes a left body 121 and a right body 122 formed in a shape corresponding to the left body 121 and coupled to the left body 121. .

That is, in the present embodiment, the cyclone unit 110 forms a complete shape by combining three bodies 112, 121, and 122. The left body 121 is coupled to the right body 122 in the cyclone axial direction. Here, the cyclone axis means the central axis of cyclone flow.

Thus, as the three bodies 112, 121, and 122 are combined to complete the cyclone unit 110, the cyclone unit 110 may be easily manufactured.

That is, the number of molds for forming the bodies 112, 121, 122 can be reduced when the bodies 112, 121, and 122 are manufactured, respectively, rather than when manufacturing one complete cyclone unit. Since the structure is simplified, the production of each of the body (112, 121, 122) is easy, and the manufacturing cost of the cyclone unit 110 can be reduced.

The first cyclone body 112 is provided with a dust discharge portion 114 for discharging dust separated from the air. The dust discharge part 114 is formed at the center of the first cyclone body 112. In addition, the first cyclone body 112 is provided with a coupling lever 113 to be coupled with the second cyclone body 120.

In addition, the first cyclone body 112 is provided with a pair of hinges 115 to be rotatably coupled to the second cyclone body 120. As the first cyclone body 112 is rotatably coupled to the second cyclone body 120, the inside of the cyclone unit 110 is rotated while the first cyclone body 112 is rotated. Cleaning can be facilitated.

Meanwhile, suction parts 123 and 124 are formed in the left body 121 and the right body 122, respectively. The suction parts 123 and 124 are formed in the tangential direction of the bodies 121 and 122 so that cyclone flow is generated. That is, the cyclone unit 110 includes two suction parts 123 and 124. Each of the suction parts 123 and 124 is located at both sides of the dust discharge part 114.

In addition, hinge bodies 125 and 126 to which the hinges 115 of the first cyclone body 112 are coupled are formed in the bodies 121 and 122. In addition, discharge holes 137 and 138 for discharging air from which dust is separated are formed in the bodies 121 and 122, respectively. The filter members 127 and 128 are coupled around the discharge holes 137 and 138. That is, the discharge holes 137 and 138 are formed on the surfaces in which the filter members 127 and 128 are coupled to the bodies 121 and 122.

In addition, air discharge parts 129 and 130 are formed at both sides of each of the bodies 121 and 122 to allow air passing through the discharge holes 137 and 138 to be moved to the filter unit 150. The air outlets 129 and 130 surround outer portions of the bodies 121 and 122.

In addition, the air discharge parts 129 and 130 are provided with a plurality of flow path guides 133 that divide the flow path inside the air discharge part into a plurality of flow paths 130a and guide the flow of air. Herein, the structures of the air outlet parts 129 and 130 formed on the left body 121 and the right body 122 are the same, and therefore, only the structure of the air outlet parts formed on the right body 122 will be described below. do.

In detail, referring to FIG. 9, the air flowing through the discharge hole 138 is changed by the air discharge part. In addition, referring to FIG. 10, the width B of the air discharge part may be greater than the diameter of the discharge hole 138. In such a structure, a vortex of air is formed while the air passing through the discharge hole flows through the air discharge part, and thus a noise of air flow may occur.

Therefore, in the present exemplary embodiment, one or more flow path guides 133 are formed in the air discharge part 130 to divide the internal space of the air discharge part into a plurality of flow paths 130a to guide the flow of air. In this embodiment, a plurality of flow path guides are formed by way of example.

The plurality of flow path guides 133 extend in a direction parallel to the flow direction A of air. The plurality of flow path guides 133 are formed to be spaced apart at regular intervals in a direction crossing the air flow direction, substantially in a vertical direction (B).

At this time, the interval between each flow path guide 133 is formed smaller than the diameter of the discharge hole (138). In this case, the upper and lower widths of the passages 130a of the air discharge unit 130 are smaller than the diameter of the discharge hole 138.

Accordingly, the flow of air introduced into the air discharge unit 130 through the discharge hole 138 is guided by the plurality of flow path guides 133, and the respective flow paths 130a are larger than the flow path cross-sectional area of the discharge hole. Since the cross-sectional area of the flow path is small, the flow rate of air is increased, so that air vortices in the air discharge unit 130 are reduced, thereby minimizing the flow noise of air in the process of passing through the air discharge unit 130.

On the other hand, each of the bodies (121, 122) is provided with a coupling portion 133, 134 to be coupled to each other by a screw and a fastening boss 132 for coupling to the filter unit 150.

The operation of the cyclone unit will be described.

Air containing dust is sucked into the cyclone unit 110 through the pair of suction units 123 and 124. Therefore, as the air is sucked through each of the suction parts 123 and 124, a pair of cyclone flows corresponding to each other are formed in the cyclone unit 110.

As a result of the pair of cyclone flows in a single space, the flow path area of the air is increased, thereby reducing the flow path loss of the air, thereby increasing the separation performance.

In addition, as a pair of cyclone flows are generated in a single space, the size of the cyclone unit may be smaller than a structure in which one cyclone flow is generated as in the related art.

The pair of cyclone flows are generated at both sides of the cyclone unit 110 to move to the center portion, and the cyclone flows meet at the center portion. Accordingly, a stronger cyclone flow is generated in the central portion of the cyclone unit 110 than the cyclone flow generated at each of the suction parts 123 and 124.

Therefore, when a pair of cyclone flows are collected at the center portion of the cyclone unit 110, the flow strength is greater than when a single cyclone flow occurs in the same space, so that dust separation performance can be further improved. do.

In addition, the dust moved to the center portion of the cyclone unit 110 may be discharged to the outside through the dust discharge portion 114 by a strong cyclone flow, thereby improving the dust discharge performance. .

In particular, foreign matter such as hair can be easily attached to the inlet side or the inside of the dust discharge unit 114 by static electricity, and as the cyclone flow is generated on the dust discharge unit 114 side as described above, Foreign matter such as hair does not adhere to the dust discharge unit 114, and can be smoothly discharged to the outside.

Air sucked into the cyclone unit 110 as described above is moved along the inner circumferential surface of the cyclone unit 110 is moved to the center portion of the cyclone unit 110 is collected, in this process air and dust Due to the difference in weight, they are separated from each other under different centrifugal forces.

The separated dust is discharged from the central portion of the cyclone unit 110 to the dust discharge unit 114, and the discharged dust is moved along the dust discharge unit 114 to the inside of the dust collector 200. Inflow.

On the other hand, the air from which dust is separated is moved to the air discharge parts 129 and 130 through the discharge holes 137 and 138 after passing through the filter members 127 and 128. The air discharged to the air discharge parts 129 and 130 is moved by the plurality of flow path guides 133 and moved to the filter unit 150.

In addition, a hinge coupler 155 is formed at a lower side of the first case 152 to couple a pair of hinges 164 of the second case 160 to each other. In addition, a coupling protrusion 156 is formed on the first case 152 to selectively engage the coupling lever 162 of the second case 160.

Therefore, in the state in which the second case 160 is rotated, the user can replace the filter 170 or clean the filter 170.

In addition, a plurality of fastening holes 157 to which screws are fastened are formed in the first case 152. Therefore, when the screw is fastened to the plurality of fastening holes 157, the screw is fastened to the fastening boss 132 of the cyclone unit 110, the filter unit 150 and the cyclone unit 110 Is combined. In addition, the second case 160 has a discharge port 161 through which the air passing through the filter 170 is discharged.
