Abstract

A vacuum cleaner, in which a dust bag or a cyclone dust collecting apparatus can be selectively mounted, includes a body case having a dust collecting chamber and a connecting hole formed at a side surface of the dust collecting chamber so that outside air enters through the connecting hole, a pair of securing brackets formed on an inner surface of the dust collecting chamber of the body case at both sides of the connecting hole in parallel with each other so that the cyclone dust collecting apparatus or the dust bag is selectively secured to the pair of securing brackets, and a body cover disposed at the body case and being opened and closed in order to open and close the dust collecting chamber.

Claims

1. A vacuum cleaner in which a dust bag or a cyclone dust collecting apparatus can be selectively mounted, the vacuum cleaner comprising:

a body case having a dust collecting chamber and a connecting hole formed at a side surface of the dust collecting chamber so that outside air enters through the connecting hole;

a pair of securing brackets formed on an inner surface of the dust collecting chamber of the body case at both sides of the connecting hole in parallel with each other so that the cyclone dust collecting apparatus or the dust bag can be selectively secured to the pair of securing brackets; and

a body cover disposed at the body case, the body cover being opened and closed in order to open and close the dust collecting chamber,

wherein the cyclone dust collecting apparatus comprises a pair of hooking members which are configured to be hooked on the pair of securing brackets disposed on the dust collecting chamber when the cyclone dust collecting apparatus is inserted in the dust collecting chamber,

if the cyclone dust collecting apparatus is used, the cyclone dust collecting apparatus is secured with the pair of securing brackets, and

if the dust bag is used, the dust bag is secured with the pair of securing brackets.

2. The vacuum cleaner of claim 1, wherein the body case comprises a sealing member disposed at the connecting hole of the dust collecting chamber;

wherein when the cyclone dust collecting apparatus is mounted in the dust collecting chamber, the sealing member contacts an air entering pipe of the cyclone dust collecting apparatus, and when the dust bag is mounted in the dust collecting chamber, the sealing member contacts a securing plate of the dust bag.

3. The vacuum cleaner of claim 2, wherein the sealing member comprises a front surface configured to form an obtuse angle with respect to a bottom surface of the dust collecting chamber.

4. The vacuum cleaner of claim 1, wherein the body cover comprises an accessory chamber.

5. The vacuum cleaner of claim 4, wherein the body cover further comprises an accessory chamber cover to cover the accessory chamber.

6. A vacuum cleaner comprising:

a dust bag;

a cyclone dust collecting apparatus;

a body case having a dust collecting chamber and a connecting hole formed at a side surface of the dust collecting chamber so that outside air enters through the connecting hole;

a pair of securing brackets formed on an inner surface of the dust collecting chamber at sides of the connecting hole so that either a cyclone dust collecting apparatus or a dust bag can be selectively secured to the pair of securing brackets; and

a body cover disposed at the body case, the body cover being opened and closed in order to open and close the dust collecting chamber,

wherein if the cyclone dust collecting apparatus is used, the cyclone dust collecting apparatus is secured with the pair of securing brackets, and

if the dust bag is used, the dust bag is secured with the pair of securing brackets.

7. The vacuum cleaner of claim 6, wherein the cyclone dust collecting apparatus comprises a pair of hooking members, and when the cyclone dust collecting apparatus is inserted in the dust collecting chamber, the pair of hooking members is configured to be hooked on the pair of securing brackets disposed on the dust collecting chamber.

8. The vacuum cleaner of claim 7, wherein the cyclone dust collecting apparatus is adapted to draw in and discharge the outside air via a lower portion thereof.

9. The vacuum cleaner of claim 8, wherein the cyclone dust collecting apparatus comprises:

a cyclone body configured so that the outside air upwardly whirls and dust is separated from the outside air;

a dust collecting container around the cyclone body to collect the dust separated by the cyclone body;

an air entering pipe connected with the lower portion of the cyclone body through the dust collecting container, the air entering pipe to guide the outside air entering through the connecting hole to the lower portion of the cyclone body; and

an air-discharging pipe disposed at a center of the cyclone body, the air-discharging pipe to discharge the outside air having the dust removed.

10. The vacuum cleaner of claim 9, wherein the air entering pipe has an end formed with an angle corresponding to a front surface of the sealing member.

11. The vacuum cleaner of claim 10, wherein the cyclone dust collecting apparatus further comprises a filter member disposed at a side of the dust collecting container, and the filter member is in fluid communication with the air-discharging pipe.

12. The vacuum cleaner of claim 10, wherein the cyclone dust collecting apparatus further comprises a cyclone cover that is detachably disposed at an upper portion of the dust collecting container.

13. The vacuum cleaner of claim 12, wherein the cyclone cover comprises a cover handle disposed on a top surface of the cyclone cover.

14. The vacuum cleaner of claim 12, wherein the cyclone cover is formed of a transparent material.

15. The vacuum cleaner of claim 6, wherein the cyclone dust collecting apparatus is configured so that the dust separated in the cyclone body is discharged into the dust collecting container over a top end of the cyclone body.

16. The vacuum cleaner of claim 6, wherein the dust bag comprises a securing plate being hooked on the pair of securing brackets.
