The vacuum cleaner includes a dust collecting unit detachably assembled in an accommodating part of a cleaner body to collect dust or dirt drawn in from the cleaner body. The dust collecting unit includes a dust bin to collect the dust or dirt, a handle provided on an side of the dust bin, a cover to open and close the dust bin, and a locking member having one end fixed on an upper surface of the cover and the other end projected outside from the cover while being elastically supported. The dust collecting unit is configured, so that when the dust collecting unit is assembled in the accommodating part, the dust collecting unit is inserted into the accommodating part in a state where the handle is gripped and thus the locking member is elastically fixed to an inner side of the accommodating part, and when the dust collecting unit is separated from the accommodating part, the handle is pulled to draw out the dust collecting unit from the accommodating part in a state where the other end of the locking member is pushed down.
Description
- The present invention relates to a cleaner, and more particularly, to a dust collecting unit of a vacuum cleaner, which is mounted in a cleaner body to collect dust or dirt drawn in along with air from the outside of the cleaner body and to discharge the dust-removed air.
- Generally, a vacuum cleaner generates a suction force by using a suction motor installed in a cleaner body, and draws in dust or dirt along with air from a surface to be cleaned by using the suction force. The drawn-in air laden with the dust or dirt is deprived of the dust or dirt while passing through a dust collecting unit, and thus only the purified air is discharged to the outside of the cleaner body.
- Such a conventional vacuum cleaner has a locking unit, which locks a dust bin detachably mounted in the cleaner body, as disclosed in
Korean patent publication No. 1991-10792 - On the other hand, in the conventional vacuum cleaner, if the dust bin is to be mounted in the cleaner body, a user grips a handle of the locking unit with one hand and at the same time, pulls the handle in an outward direction of the cleaner body to allow the handle to have a certain elastic force. In such a state, the user inserts the dust bin into the cleaner body with the other hand, and then releases the handle of the locking unit to restore it to an original position. Also, if the dust bin is to be separated from the cleaner body, the user also separates the dust bin by an operation of three steps like as in the operation of mounting the dust bin. Accordingly, there is troublesome in that in mounting and separating the dust bin, the user should not only go through the operation of several steps, but also use both hands.
- In addition, since the dust bin is maintained in a state where it is seated in the cleaner body only by its own weight, there is a problem that if an external impact is imposed on the cleaner body or the dust bin, the cleaner body and the dust bin are not stably sealed to each other.
- On the other hand, in
Korean patent publication No. 2001-499225 - However, in this case, since a construction for locking the dust bin in the cleaner body is complicated, there is a problem that it is inconvenient to maintain and repair the product. Also, in mounting the dust bin, the user should insert the dust bin in the cleaner body in a state where she or he grips the dust bin, and then rotate the lever, and in separating the dust bin, rotate the lever and then draw out the dust bin from the cleaner body. Accordingly, to mount or separate the dust bin, the user should go through the operation of at least two steps.
- The present invention has been developed in order to solve the above problems in the related art. Accordingly, an aspect of the present invention is to provide a vacuum cleaner capable of assembling and separating a dust collecting unit by an operation of single step.
- Another aspect of the present invention is to provide a vacuum cleaner capable of simplifying a locking structure between a dust collecting unit and cleaner body while superiorly sealing therebetween.
- The above aspects are achieved by providing a vacuum cleaner including a dust collecting unit detachably assembled in an accommodating part of a cleaner body to collect dust or dirt drawn in from the cleaner body, and having a dust bin to collect the dust or dirt, a handle provided on an side of the dust bin, a cover to open and close the dust bin, and a locking member having one end fixed on an upper surface of the cover and the other end projected outside from the cover while being elastically supported. The dust collecting unit is configured, so that when the dust collecting unit is assembled in the accommodating part, the dust collecting unit is inserted into the accommodating part in a state where the handle is gripped and thus the locking member is elastically fixed to an inner side of the accommodating part, and when the dust collecting unit is separated from the accommodating part, the handle is pulled to draw out the dust collecting unit from the accommodating part in a state where the other end of the locking member is pushed down. Accordingly, the dust collecting unit can be assembled into or separated from the cleaner body by an operation of single step of using one hand.
- The locking member may have a hanging projection formed on an upper surface thereof adjacent to the other end thereof, and the accommodation part may have a hanging groove formed in an upper side surface thereof to accommodate the hanging projection. Accordingly, the dust collecting unit can be assembled and fixed in the accommodation part without being freely moved. Moreover, the hanging projection may have an inclined surface downwardly inclined in a direction of assembling the dust collecting unit into the accommodating part, and a vertical surface formed in a direction of drawing out the dust collecting unit from the accommodating part. As the dust collecting unit is assembled into the accommodating part through the inclined surface as described above, it can be stably assembled in the accommodating part only by the operation of inserting the dust collecting unit into the accommodating part.
- The cover may have a projecting part formed on a side of a circumference thereof to accommodate the other end of the locking member, and the projecting part may have a return spring disposed on an inner side thereof to elastically support the other end of the locking member. With such a return spring, an undersurface of the dust collecting unit is strongly pressed and placed on a seating surface of the accommodating part, and thus the dust collecting unit is superiorly sealed to the cleaner body.
- Preferably, but not necessarily, the locking member is configured, so that the other end is spaced apart from the upper surface of the cover to allow a pushing part formed thereon to move un and down.
- To facilitate the operation of inserting or separating the dust collecting unit into or from the accommodating part, the dust collecting unit may be inclinedly disposed in the direction, which is assembled into the accommodating part of the cleaner body.
- The above aspects and other advantages of the present invention will be more apparent by describing an exemplary embodiment of the present invention with reference to the accompanying drawing figures, in which:
-

hose 7 is detachably coupled to thecleaner body 10 to connect the suction nozzle 1 to ahose connecting part 11 in front of thecleaner body 10 and thus to guide the dust or dirt drawn in from the surface to be cleaned into thecleaner body 10. Also, anaccommodating part 12 is projected and formed in front of thecleaner body 10 to assemble the dust collectingunit 100 therein. In this case, theaccommodating part 12 is formed, so that aseating surface 14 on which the dust collectingunit 100 is seated and anupper side surface 16 with which an upper surface (seeFIG. 3 ) of acover 130 of thedust collecting unit 100 is in contact are downwardly inclined in a direction of assembling the dust collectingunit 100. According to this, when the dust collectingunit 100 assembled in the inclined state in theaccommodating part 12 is drawn out from the cleaner body, which is usually placed and seated on the surface to be cleaned in use, a user, which is in a position higher than thecleaner body 10, comes to easy to draw out thedust collecting unit 100. On the other hand, thecleaner body 10 has a suction motor (not illustrated) disposed in the inside of the rear thereof, and wheels 20 mounted on both sides of the rear thereof to allow the vacuum cleaner to smoothly move onto the surface to be cleaned. - Although the dust collecting
unit 100, which will be described below with reference toFIGS. 3 through 8 , is explained by way of showing an example as having a cyclone structure for centrifugally separating the dust or dirt from air and a space for collecting the dust or dirt together therein, the present invention is not limited thereto.

In this case, acoupling groove 130a (seeFIG. 6 ) is formed on an undersurface of thecover 130 along an outer edge of thecover 130 to accommodate a top of the upper part of thebody 110 and couple therewith, and apacking 131 is inserted in thecoupling groove 130a to prevent a suction force from being reduced in thedust collecting unit 100. In addition, thecover 130 has acountercurrent prevention prominence 133 projected inside, that is, downward, from an undersurface thereof to have a diameter larger than thecylindrical part 123. Accordingly, the dust or dirt discharged into thedust collecting space 129 through adust discharging space 134 by the centrifugal force is prevented from being flowed backward again into thecylindrical part 123 through thedust discharging space 134. Also, thecover 130 has arecessed part 132 gently recessed downward from the middle of the upper surface thereof. Therecessed part 132 prevents afixing part 171 to be described below from highly projecting beyond the upper surface of thecover 130. Accordingly, when thedust collecting unit 100 is assembled in or separated from theaccommodating part 12 of thecleaner body 10, the fixingpart 171 is prevented from hanging on a front end 19 (seeFIG. 7 ) of theaccommodating part 12, thereby allowing thedust collecting unit 100 to smoothly assemble or separate. - Referring to
FIGS. 4 and7 , thecover 130 has a projectingpart 135 with anaccommodating groove 135a formed on one side of a circumference thereof. A pushingpart 175 to be described later is disposed to be move up and down in theaccommodating groove 135a, and areturn spring 160 is disposed in theaccommodating groove 135a to elastically support a lower end of the pushingpart 175. Thereturn spring 160 at both ends thereof is fixed by afirst fixing projection 161 of theaccommodating groove 135a and asecond fixing projection 162 of an undersurface of the pushingpart 175. - Referring to
FIG. 5 , thehandle 150 has agripping part 151 disposed in a longitudinal direction of thebody 110. Thegripping part 151 at upper and lower ends thereof is connected to upper side and lowerside connecting parts body 110, so that it is maintained in a spaced-apart from thebody 110. The upperside connecting part 153 at an upper surface thereof has aseating groove 153a in which the projectingpart 135 of thecover 130 is seated. In this case, the upperside connecting part 153 is disposed to be exposed outside of theaccommodating part 12, so that when thedust collecting unit 100 is assembled in theaccommodating part 12, the user enables the pushingpart 175 accommodated in the projectingpart 135 to easily operate. - Referring to
FIGS. 3 and5 through 8 , the lockingmember 170 includes a fixingpart 171 and anextended bar 173. The fixingpart 171 acts as a knob, which can be gripped by the user thus to easily open or close thecover 130. Such a fixingpart 171 is fixed by a fixingscrew 165 in the recessedpart 132 of thecover 130, so that it is not highly projected beyond the upper surface of thecover 130. Theextended bar 173 is extended in a certain length from one side of the fixingpart 171. Such anextended bar 173 at an approximate middle thereof has abent part 174 placed on a portion of anedge 132a of the recessedpart 132. In this case, theextended bar 173 is formed, so that a portion toward the pushingpart 175 is stepped to be higher than a portion toward the fixingpat 171 centering on thebent part 174. Accordingly, the portion of theextended bar 173 toward the pushingpart 175 is spaced apart from the upper surface of the cover 120. Therefore, the pushingpart 175 can secure a space, which is movable up and down as much as a distance spaced apart from the upper surface of the cover 120. - Also, the
extended bar 173 has a hangingprojection 177 projected upward from an upper surface thereof adjacent to the pushingpart 175. Referring toFIG. 8 , the hangingprojection 177 at one side surface thereof has aninclined surface 177a downwardly inclined in a direction of assembling the dust collecting unit100 into theaccommodating part 12 of thecleaner body 10, and at the other side surface has avertical surface 177b formed in a direction of drawing out thedust collecting unit 100 from theaccommodating part 12 of thecleaner body 10. In this case, a hanginggroove 18 in which the hangingprojection 177 is detachably inserted and fixed is formed on a front end side of theupper side surface 16 of theaccommodating part 12. - An operation of assembling the
dust collecting unit 100 in and separating from theaccommodating part 12 of thecleaner body 10 in the vacuum cleaner according to the exemplary embodiment of constructed as described above will be explained as follows. - First, as illustrated in
FIG.1 , if thedust collecting unit 100, which is in a state where it is separated from thecleaner body 10, is to be assembled in theaccommodating part 12, the user grips thegripping part 151 of thehandle 150 and then slides thedust collecting unit 100 into theaccommodating part 12 along an inclined direction corresponding to theaccommodating part 12. At this time, the hangingprojection 177 of the lockingmember 170 is slid while theinclined surface 177a comes in contact with thefront end 19 of theaccommodating part 12. According to this, theextended bar 173 of the lockingmember 170 is deformed, so that the portion toward pushingpart 175 is moved downward in a certain angle about thebent part 174 placed on theedge 132a of the recessedpart 132. At this time, thereturn spring 160 is compressed, so that an elastic supporting force of thereturn spring 160 to the portion of theextended bar 173 toward pushingpart 175 is increased. Subsequently, when thedust collecting unit 100 is completely inserted into theaccommodating part 12, the hangingprojection 177 is elastically inserted and locked in the hanginggroove 18, as illustrated inFIG. 7 . - Under such a state, even if the user pulls the
gripping part 151, the hangingprojection 177 is not released from the hanginggroove 18 due to thevertical surface 177b thereof. Since in the state where thedust collecting unit 100 is completely inserted into theaccommodating part 12 as described above, thereturn spring 160 elastically urges the upper surface of the lockingmember 170 against a portion of theupper side surface 16 of theaccommodating part 12, anundersurface 110a of thedust collecting unit 100 comes in strong contact with the seating surface 14 (seeFIG. 2 ). According to this, theinflow hole 111 and the discharginghole 113 illustrated inFIG. 4 can be maintained in a superiorly sealed state with a corresponding inflow hole (not illustrated) and a corresponding discharging hole (not illustrated) formed in theseating surface 14 to communicate therewith. Thus, thedust collecting unit 100 can be simply assembled in theaccommodating part 12 only by the operation of inserting thedust collecting unit 100 into theaccommodating part 12. - To the contrary, if the
dust collecting unit 100 is to be separated from theaccommodating part 12, the user grips the drippingpart 151 of thehandle 150 and at the same time, pulls thehandle 150 in a drawing-out direction while pushing down the pushingpart 175 with her or his thumb to completely separate the hangingprojection 177 from the hanginggroove 18. According to this, thedust collecting unit 100 is separated from theaccommodating part 12. Thus, the operation of separating thedust collecting unit 100 from theaccommodating part 12 can be also simply carried out, particularly, only by using one hand. - As apparent from the foregoing description, according to the exemplary embodiment of the present invention, the vacuum cleaner is advantageous in that the dust collecting unit can be assembled in or separated from the cleaner body by the operation of single step.
- Further, the vacuum cleaner according to the exemplary embodiment of the present invention has the simple locking structure, which fixedly locks the dust collecting unit in the accommodating part of the cleaner body. Accordingly, the vacuum cleaner according to the exemplary embodiment of the present invention is easy to maintain and repair.
- Also, the vacuum cleaner according to the exemplary embodiment of the present invention is configured, so that the dust collecting unit assembled in the accommodating part of the cleaner body is maintained in the superiorly sealed state with the cleaner body, thereby improving the reliability of product.
