The air flowing into the primary cyclone portion 214 is not directly introduced into the outlet portion 217 by the first suction port 214a and the guide rib 218, but the primary cyclone portion ( The inner wall of the 214 is tangentially guided to form a spiral flow.

Accordingly, the dust having a relatively heavy weight and large dusts are separated and lowered by the cyclone principle, and are stored in the primary dust storage unit 212, and the dust stored in the primary dust storage unit is scattering prevention member 219. And scattering are prevented by the curved boundary wall 216.

In addition, the air from which the relatively large dusts are separated is discharged to the first exhaust port 214b communicating with the plurality of holes formed on the side of the outlet portion 217 and then to the plurality of secondary cyclone portions 215. It enters and goes through the dust separation process again.

Air from which relatively small dusts are separated from the secondary cyclone portion 215 is introduced into the upper cover 230 through the second exhaust mechanism 215b.

After the air flowing into the upper cover 230 is filtered by the filter, the air is discharged backward through the third exhaust port 233, and the air discharged from the third exhaust port 233 is rear part of the cleaner body. Is discharged to the outside of the cleaner body through a predetermined flow path formed in the

Referring to Figure 5, the structure of the upper cover and the dust container cover will be described in detail.

The dust collecting container 210 is configured to include a dust separating unit for separating foreign matters from the incoming air and a dust storage unit for storing the separated dust, and the dust collecting container cover 220 for opening and closing the dust collecting container on the upper part of the dust collecting container. Is installed. In addition, the upper cover 230 is detachably coupled to the upper portion of the dust container cover 220. In addition, the upper cover and the dust collecting container cover are provided with alignment indicators 228 and 238 which indicate the direction in which the upper cover and the dust collecting container cover are coupled.

The dust collecting container is provided with a first suction opening 214a through which air containing foreign matter is sucked, and a lower panel 211 forming a bottom of the dust collecting container is formed. In addition, an opening and closing device 213 for opening and closing the lower panel 211 is installed at the side portion of the dust collecting container.

A protrusion 222 having a predetermined shape is formed on an outer circumferential surface of the dust container cover, and a coupling groove 232 corresponding to the protrusion 222 is formed on an inner circumferential surface of the upper cover. Of course, the protrusion is formed in the upper cover, the coupling groove may be formed in the dust container cover. In addition, a first alignment indicator 228 protruding downwardly is formed at one side of the outer circumferential surface of the dust collecting container cover to indicate a position where the dust collecting container cover 220 and the upper cover 230 are coupled.

The protrusion 222 may include a first protrusion 222a formed to have a predetermined length in the circumferential direction of the dust collecting container cover, a second protrusion 222b formed to have a predetermined angle with the first protrusion, and an upper cover. It is configured to include a locking projection (222c) for limiting the rotation.

At least one protrusion 222 is formed, and at least one of the gaps between the protrusions has a different distance. More specifically, the protrusion 222 is formed three, it is preferable to be formed at intervals of 110 °, 110 °, 140 ° along the circumferential direction of the dust container cover. Of course, the interval between the protrusions may have any interval. In this embodiment, by varying one of the intervals between the projections it can be installed in the correct position when the top cover is combined with the dust collector cover.

In addition, a locking protrusion 222c is formed in a space formed by the first protrusion 222a and the second protrusion 222b, and the first protrusion 222a and the second protrusion 222b are vertically formed. desirable. In addition, the shape of the locking protrusion 222c preferably has a predetermined inclination angle in one side direction. This is because the protrusion 222 is inserted into the coupling groove 232 to facilitate insertion of the locking protrusion when moving in the circumferential direction of the upper cover.

The filter exhaust part 236c is inclined to have a predetermined inclination angle. More specifically, the inclination angle of the filter exhaust part 236c is inclined downward in the direction of the third exhaust port housing 233a. . This is because, when the filter 237 is installed in the filter housing 236, the filtering efficiency can be increased while occupying a minimum space.

An inner circumferential surface of the filter housing is formed with a coupling groove 232 having a predetermined shape and a molding groove 239 for maintaining a constant strength of the filter housing. In addition, a second alignment indicator 238 is provided on the outer circumferential surface of the filter housing to indicate a direction in which the upper cover 230 and the dust container cover 220 are coupled to each other. The second alignment indicating unit 238 corresponds to the first alignment indicating unit 228 formed on the dust container cover, and preferably at least one second alignment indicating unit 238 is formed.

The coupling groove 232 corresponds to the protrusion 222 formed on the outer circumferential surface of the dust collecting container cover 220, so that the upper cover 230 is detachably coupled to the dust collecting container cover 220.

Next, by pressing the upper cover 230, the protrusion 222 formed on the dust collecting container cover is inserted into the coupling groove formed in the upper cover. Thereafter, the protrusion relatively rotates the protrusion and the coupling groove so as to be rotatable inside the coupling groove. That is, to allow the protrusion to be coupled to the coupling groove, the upper cover 230 and the dust collecting container 210 is grasped and rotated in opposite directions. Then, the protrusion 222 is moved along the circumferential direction of the dust collecting container cover inside the rotary groove 232b which is a part of the coupling groove. Then, when the locking projections come to the position where the locking projection is formed while relatively rotating the engaging portion, by applying a force in the rotational direction so that the locking projection is seated on the locking groove.
