A vacuum cleaner 10 according to an embodiment of the present invention includes a vacuum cleaner main body 11, a suction brush 13, and a dust collecting device 100.

The cleaner main body 11 has a suction motor (not shown) as a vacuum source on the inside thereof, and has an intake pipe (not shown) and an exhaust pipe (not shown), each of which is detachably connected to the dust collector 100. In addition, the cleaner main body 11 is provided with a handle 15 at an upper portion thereof so that the user can easily move the cleaner main body 11 on the surface to be cleaned.

The rear end of the suction brush 13 is hinged to the lower end of the cleaner main body 11 and sucks dirt present on the surface to be cleaned through the suction port (not shown) on the bottom surface of the suction brush 13.

The dust collecting apparatus 100 includes a cyclone unit 110, a dust receptacle 120, a lever unit 130, a coupling unit 140 (see FIG. 2), a guide unit 150 ).

The cyclone part 110 is sucked from the surface to be cleaned through the suction brush 13 and separates the dirt from the inflow air guided through the suction tube (not shown). Further, the cyclone part 110 discharges the air separated from the dirt to a discharge pipe (not shown). The cyclone unit 110 is detachably disposed in the receiving portion 12a of the cleaner main body 11 by a separate fixing device (not shown).

The dirt receptacle 120 is disposed below the cyclone part 110 so as to communicate with the upper part of the dirt receptacle 120 and collects the freely falling dirt separated from the air from the cyclone part 110.

The lever 130 functions to move the dirt receptacle 120 up and down and to bind the dirt receptacle 120 to the lower end of the cyclone unit 110 in a compressed state. Airtightness is maintained between the cyclone part 110 and the dirt receptacle 120 according to the operation of the lever part 130. This prevents the suction force inside the dust collecting apparatus 100 from being lowered and prevents leakage of air or dirt from the dust collecting apparatus 100 to prevent the leakage of dust or dirt from the receiving groove 12a of the cleaner main body 11 or the vicinity of the vacuum cleaner 10 Can be prevented from being contaminated by the leaking dirt.

A structure for lifting or lowering the dirt receptacle 120 according to the operation of the lever 130 will be described. 4, the dust receptacle 120 has a central groove 124 which is recessed inward at the center of the bottom, a first cylindrical projection 125 at the center of the central groove 124, The outer periphery of the projection 125 has a pair of first slant projections 126a and 126b. A restriction groove 123 (see FIG. 4) for limiting the turning angle of the handle 133 (see FIG. 2) of the lever portion 133 is formed on one side of the central groove 124. 2, the lever portion 130 is inserted in such a manner that the rotation portion 131 is rotatable in the central groove 124. As shown in Fig. A second cylindrical protrusion 135 is formed at the center of the rotation part 131. A pair of first slant protrusions 126a and 126b (see FIG. 4) Two oblique projections 137a and 137b (see Fig. 2) are formed. The second slant projections 137a and 137b pivoting together with the lever portion 130 are engaged with the first slant projections 126a and 126b So that the dirt receptacle 120 is lifted or lowered by a height corresponding to the turning angle of the handle 133.

2, the coupling unit 140 includes a coupling groove 141 formed in the receiving portion 12a of the cleaner main body 11 and a coupling protrusion 145 snap-engaged with the coupling groove 141 . In this case, it is preferable that the coupling protrusion 145 is made of a synthetic resin having a certain elastic force so as to be elastically coupled to the coupling groove 141. Further, both sides of the engaging groove 141 and the engaging projection 145 that are in contact with each other are concavo-convex. That is, as shown in FIGS. 3A and 3B, the coupling groove 141 is formed with concave portions 143a and 143b along the vertical direction on both sides. The protrusions 146a and 146b are formed on the front edge of the coupling protrusion 145 so that the coupling protrusions 145 are respectively inserted into the recesses 143a and 143b on both sides when snap- These projecting portions 146a and 146b are formed in the vertical direction so as to correspond to the concave portions 143a and 143b, respectively. The protrusions 146a and 146b are formed to be slightly larger than the volumes of the concave portions 143a and 143b to induce a strong coupling when they are coupled to the concave portions 143a and 143b.

7b, the coupling groove 141 and the coupling protrusion 145 are formed so that the upper end of the coupling groove 141 and the coupling protrusion 145 are coupled to the lower end of the cyclone unit 110, When the engaging projection 145 is engaged with the engaging projection 145, a predetermined clearance G is formed between the inner upper surface 143c of the engaging groove 141 and the upper surface 146c of the engaging projection 145 . 6, the height H1 of the coupling groove 141 is formed to be larger than the height H2 of the coupling projection 145, and the reason why the clearance G has such a clearance G is that the coupling unit 140 The dirt receptacle 120 moves up and down to a horizontal position without being inclined to the fixed side by the coupling unit 140 so that the cyclone unit 110 can move up and down, It can be joined at the bottom to maintain airtightness. As a result, the dirt receptacle 120 is naturally lifted and lowered in a state in which the dirt receptacle 120 is stably fixed in the accommodating portion 12a by the turning operation of the lever portion 130. [

The guide unit 150 includes a pair of guide grooves 153a and 153b (see FIG. 4) formed below the dust receptacle 120 in parallel in the longitudinal direction and a dust receptacle 120 And a pair of guide protrusions 151a and 151b (refer to FIG. 3A) formed on the seating surface 12b (see FIG. 3A) of the cleaner main body 11 on which the lower ends of the guide protrusions 151 are seated. When the dust collecting apparatus 100 is inserted into the accommodating portion 12a of the cleaner main body 11, the guide unit 150 is rotated such that the engaging protrusions 145 of the engaging unit 140 are correctly engaged with the engaging grooves 141 So that the user can easily engage the engaging groove 141 and the engaging projection 145 with each other.

Accordingly, the embodiment of the present invention restricts the left-right rotation of the dust receptacle 120 through the guide unit 150 and constrains the back-and-forth movement of the dust receptacle 120 through the coupling unit 140, The dirt receptacle 120 can be fixed in three dimensions at one side and the bottom of the body 120.
