The present invention relates to a vacuum cleaner. More particularly, the present invention relates to a vacuum cleaner capable of separating a dust bin and a main body from each other.

Description of the Related Art

FIG. 1 is an exploded perspective view exemplifying a conventional vacuum cleaner in a state in which a dust bin 2 is separated from a main body 3. Referring to FIG. 1, the vacuum cleaner includes a dust bin 2 to separate contaminant, such as dust or dirt, from drawn-in air and to store it therein, and a main body 3 having a driving motor (not illustrated) mounted therein to produce a suction force.
The dust bin 2 and the main body 3 are provided with two passages connected to each other, one of which is an air inflow passage 5 to draw in air laden with contaminant and the other of which is an air outflow passage 6 to discharge contaminant-removed air. With this construction, the drawn-in air first purified by the dust bin is discharged outside the main body 3 via a filter (not illustrated) for removing fine dust by the suction force of the driving motor.
To mount the dust bin 2 in the main body 3, the conventional vacuum cleaner includes a transverse member 4. The transverse member 4 is disposed in a radial direction on an upper part of the dust bin 2 and has a convex part 4a formed on a top thereof and a button 4b formed at one end thereof. A concave part 8 is formed corresponding to the convex part 4a of the dust bin 2 in the main body 3.
However, such a conventional vacuum cleaner is inconvenient in that to mount the dust bin 2, a user should undergo trial and error, which requires rotating or moving the dust bin 2 here and there to lock the convex part 4a in the concave part 8, after pushing the dust bin 2 into the main body 3.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT

Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIGS. 2A and 2B are perspective views exemplifying a dust bin 20 and a main body 30 of a vacuum cleaner according to an exemplary embodiment of the present invention, which are separated from each other, respectively, and FIG. 3 is a cross-sectional view exemplifying the vacuum cleaner according to the exemplary embodiment of the present invention in which the dust bin 20 and the main body 30 are combined with each other.
Referring to the drawings, the vacuum cleaner according to the exemplary embodiment of the present invention includes a dust bin 20 having a handle 26 attached thereto, and a main body 30 having a mounting chamber in which the dust bin 20 is mounted. The dust bin 20 is slid into and mounted in the main body 30. For this, a sliding part 21 is formed on an upper part of the dust bin 20, and a guide part 31 is formed inside an upper part of the main body 30 to guide the sliding part 21 of the dust bin 20 when the dust bin 20 is slid and inserted into the main body 30. The sliding part 21 is formed of a bar-shaped elongated member extended in an inserting direction thereof, and the guide part 31 is formed of a groove corresponding to the bar-shaped elongated member.
The dust bin 20 and the main body 30 are provided with a locking unit. The locking unit has a swing member 23, a spring 25, and a pressing member 22. The swing member 23 is configured, so that the convex part 23a is formed on one end thereof and a hinge axis 24 is formed on the middle thereof. The spring 25 as an elastic member is located on one end of the swing member 23. The pressing member 22 is disposed on the other end of the swing member 23 so as to be pressed by a user. A concave part 32 is formed at a position corresponding to the convex part 23a of the dust bin 20 in the main body 30.
In the exemplary embodiment of the present invention, the pressing member 22 is located in a vertical part of the handle 26. A releasing button 22a is projected outside the handle 26 from a top of the pressing member 22, so that it can be pressed by the user. The swing member 23 is horizontally disposed in a lower part of the handle 26, and has a hinge axis 24 at the middle thereof, so that it can swing. The convex part 23 a formed on the one end of the swing member 23 is formed in a shape inclined in sympathy with a main body (30) direction, and has a sill raised against an opposite direction to the main body (30) direction. The spring 25 is mounted on an opposite side to a side of the one end of the swing member 23 on which the convex part 23a is formed, so that it pushes down the swing member 23. According to this, the convex part 23a is locked in the concave part 32 of the main body 30.
A reference numeral 35 represents a passage to draw in air laden with contaminant, such as dust or dirt, a reference numeral 36 represents a motor and blade part to produce a suction force, and a reference numeral 37 represents a filter and discharge part to remove the contaminant from the air and discharge it.
A method of mounting the dust bin 20 in the vacuum cleaner constructed as described above is as follows. First, a user grips the handle 26 and then aligns the sliding part 21 of the dust bin 20 with the guide part 31 of the main body 30. And then, the dust bin 20 is pushed in a main body (20) direction. As a result, the sliding part 21 of the dust bin 20 is guided by the guide part 31 and thus the dust bin 20 is mounted into the main body 30 without seceding from the inside of the main body 30. At this time, since the convex part 23a is inclined in an inserting direction thereof, it does not disturb the sliding motion of the dust bin 20.
After that, when the dust bin 20 is continuously pushed and thus completely inserted into the main body 30, the convex part 23a is locked in the concave part 32. At this time, the swing member 23 clicks while impacting the main body 30. As a result, the dust bin 20 is mounted in and fixed to the main body 30.
In a condition as described above, the dust bin 20 is maintained in a stably mounted state because a rocking thereof from side to side is prevented by the sliding part 21 and the guide part 31 and a shaking thereof in front and in the rear is prevented by the concave part 32 and the convex part 23a.
Next, a method of dismounting the dust bin 20 will be explained as follows. When the user pushes the releasing button 22a formed on the handle 26 of the dust bin 20 with her or his thumb, the pressing member 22 moves downward and presses the swing member 23. The pressed swing member 22 is swung about the hinge axis 24. According to this, the convex part 23a of the swing member 23 is moved upward and left from the concave part 32 to release a locking state to the dust bin 20.
When the locking state of the dust bin 20 is released, the dust bin 20 can be easily dismounted from the main body 30 by pulling the dust bin 20 in an opposite direction to the main body (30) direction. Preferably, but not necessarily, the dust bin 20 as described above is configured to include a cyclone dust-separating apparatus, which separates dust or dirt from air by a centrifugal force.
As apparent from the foregoing description, according to the exemplary embodiment of the present invention, the vacuum cleaner is capable of easily mounting the dust bin in the main body, and maintaining the dust bin in the stable state even though it is rocked from side to side and shaken in front and in the rear.
Although a representative embodiment of the present invention has been shown and described in order to exemplify the principle of the present invention, the present invention is not limited to the specific embodiment. It will be understood that various modifications and changes can be made by one skilled in the art without departing from the scope of the invention as defined by the appended claims. Therefore, it shall be considered that such modifications, changes and equivalents thereof are all included within the scope of the present invention.
