Abstract

Disclosed related to a vacuum cleaner comprising a cleaner body in which a dust collector mount part is formed; a dust collector attached and removed at the dust collector mount part, and having a dust storage part in the inside; at least one of the compressing member reducing the volume of the dust stored in the dust storage part as arranged in the dust storage part movably; a power transfer unit transferring the driving force to the compressing members from outside as connected with the compressing members; and a control unit deciding the amount of the dust stored in the dust storage unit.

Claims

1. A vacuum cleaner, comprising:

a main body including a suction motor that generates a suction power and a mounting part;

a dust separator that communicates with the suction motor and separates dust and dirt from air;

a dust collector body configured to store dust separated from the dust separator, the dust collector body being detachably mounted on the mounting part of the main body;

at least one plate provided within the dust collector body and configured to compress dust stored in the dust collector body; and

a transfer device comprising at least one gear provided outside of the dust collector body, the transfer device being configured to transfer a driving force to the at least one plate, wherein the mounting part of the main body includes a receptacle that receives at least a portion of the transfer device in a state in which the dust collector body is mounted on the mounting part of the main body.

2. The vacuum cleaner according to claim 1, wherein the dust collector body includes a cover that covers at least a portion of the transfer device, and wherein the cover is received in the receptacle in a state in which the dust collector body is mounted on the mounting part of the main body.

3. The vacuum cleaner according to claim 1, further comprising a first guide configured to guide mounting of the dust collector body on the mounting part of the main body and formed on the dust collector body, and a second guide configured to interact with the first guide and formed on the dust collector body.

4. The vacuum cleaner according to claim 3, wherein the first guide comprises at least one protrusion that protrudes from the dust collector body, and the second guide comprises an insertion groove in which the at least one protrusion is inserted formed on the mounting part of the main body.

5. The vacuum cleaner according to claim 3, wherein the first guide comprises a set groove formed on a lower side of the dust collector body, and the second guide comprises a set protrusion inserted into the set groove formed on the mounting part of the main body.

6. The vacuum cleaner according to claim 1, further comprising a drive device that generates the driving force to move the at least one plate and a driving gear connected to the drive device, wherein the at least one gear of the transfer device includes a driven gear engaged with the driving gear.

7. The vacuum cleaner according to claim 6, wherein the drive device and the driving gear are each provided on the main body.

8. The vacuum cleaner according to claim 7, wherein at least a portion of the driving gear is located in the receptacle.

9. The vacuum cleaner according to claim 1, wherein the transfer device is provided at a lower side of the collector body.

10. The vacuum cleaner according to claim 1, wherein the receptacle comprises a recess formed in the mounting part of the main body.

11. The vacuum cleaner according to claim 1, wherein the at least one plate comprises a plurality of protrusions disposed on a surface thereof.

12. A vacuum cleaner, comprising:

a main body including a suction motor that generates a suction power and a mounting part;

a dust separator that communicates with the suction motor and that separates dust and dirt from air;

a dust collector body configured to store dust separated from the dust separator, the dust collector body being detachably mounted on the mounting part of the main body;

at least one plate provided within the dust collector body and configured to compress dust stored in the dust collector body;

a drive device configured to generate a driving force to move the at least one plate;

a first guide provided on the dust collector body and configured to guide mounting of the dust collector body on the mounting part of the main body; and

a second guide provided on the mounting part of the main body and configured to interact with the first guide, wherein at least a portion of the drive device is located at the mounting part when the dust collector body is mounted on the mounting part, and wherein the first guide comprises at least one protrusion that protrudes from the dust collector body, and the second guide comprises an insertion groove in which the at least one protrusion is inserted formed on the mounting part of the main body.

13. A vacuum cleaner, comprising:

a main body including a suction motor that generates a suction power and a mounting part;

a dust separator that communicates with the suction motor and separates dust and dirt from air;

a dust collector body configured to store dust separated from the dust separator, the dust collector body being detachably mounted on the mounting part of the main body;

at least one plate provided within the dust collector body and configured to compress dust stored in the dust collector body;

a drive device configured to generate a driving force to move the at least one plate;

a first guide provided on the dust collector body and configured to guide mounting of the dust collector body on the mounting part of the main body; and

a second guide provided on the mounting part of the main body and configured to interact with the first guide, wherein at least a portion of the drive device is located at the mounting part when the dust collector body is mounted on the mounting part, and wherein the first guide comprises a set groove formed at a lower side of the dust collector body, and the second guide comprises a set protrusion inserted into the set groove formed on the mounting part of the main body.

14. The vacuum cleaner according to claim 13, further comprising a transfer device comprising at least one gear configured to transfer the driving force from the drive device to the at least one plate, wherein the at least one gear comprises a plurality of gears, and wherein at least one of the plurality of gears is connected to the at least one plate.

15. The vacuum cleaner according to claim 14, wherein the at least one of the plurality of gears is provided under the dust collector body.

16. The vacuum cleaner according to claim 15, wherein the first guide covers at least a portion of the at least one of the plurality of gears.
