Abstract

There is provided a vacuum cleaner. The vacuum cleaner includes a dust separation part separating dust contained in air; a dust storing part storing dust separated by the dust separation part; a compression unit dividing the dust separation part and dust storing part, for compressing dust stored in the dust storing part; a motor connection passage communicated with a motor generating a negative pressure; a compression passage communicated with the dust storing part; a dust collection passage communicated with the dust separation part; and a flow passage control unit selectively opening and closing the compression passage and the dust collection passage.

Claims

1. A vacuum cleaner, comprising;

a dust separation part separating dust contained in air;

a dust storing part storing dust separated by the dust separation part;

a compression unit dividing the dust separation part and dust storing part, for compressing dust stored in the dust storing part;

a motor connection passage communicated with a motor generating a negative pressure;

a compression passage communicated with the dust storing part;

a dust collection passage communicated with the dust separation part; and

a flow passage control unit selectively opening and closing the compression passage and the dust collection passage.

2. The vacuum cleaner according to claim 1, wherein the dust collection passage and the compression passage are selectively communicated with the motor connection passage.

3. The vacuum cleaner according to claim 1, further comprising a main passage communicated with the motor connection passage and selectively communicated with the dust collection passage and the compression passage.

4. The vacuum cleaner according to claim 1, wherein the flow passage control unit includes a first control part selectively closing one of the dust collection passage and the compression passage, and a second control part selectively opening the other of the collection passage and the compression passage.

5. The vacuum cleaner according to claim 1, wherein the dust compression unit compresses dust stored in the dust storing part when the compression passage is opened.

6. The vacuum cleaner according to claim 1, wherein the flow passage control unit has a flow passage guiding airflow.

7. A vacuum cleaner, comprising;

a dust separation part separating dust contained in air;

a dust storing part storing dust separated by the dust separation part;

a motor connection passage communicated with a motor generating a negative pressure;

a compression passage selectively communicating the motor connection passage with the dust storing part;

a dust collection passage selectively communicating the motor connection passage with the dust separation part;

a first control part selectively closing one of the compression passage and the dust collection passage; and

a second control part selectively opening the other of the compression passage and the dust collection passage.

8. The vacuum cleaner according to claim 7, wherein the first control part is integrally formed with the second control part.

9. The vacuum cleaner according to claim 7, wherein the second control part has a flow passage guiding airflow.

10. The vacuum cleaner according to claim 7, wherein the first control part and the second control part are operated in a rotational manner.

11. The vacuum cleaner according to claim 7, further comprising a driving unit driving the first control part and the second control part.

12. The vacuum cleaner according to claim 7, further comprising a compression unit compressing the dust stored in the dust storing part when the motor connection passage is communicated with the compression passage.
