Abstract

Disclosed herein is a vacuum cleaner with an integrated handheld vacuum cleaner unit that includes a dust container detachably mounted on a body of the vacuum cleaner and configured to perform vacuum cleaning via air suction in a detached state. The dust container of the vacuum cleaner permits vacuum cleaning not only in a state of being mounted in the body, but also in a state of being detached therefrom. Accordingly, the vacuum cleaner of the present invention can eliminate needs of separately buying a larger vacuum cleaner and a smaller vacuum cleaner, thereby being more economical for consumers.

Claims

1. A vacuum cleaner with an integrated handheld vacuum cleaner unit, comprising:

a body having a hose attaching part and an accommodation part opened partially;

a dust container detachably mounted on the accommodation part and including a filter disposed in the dust container to collect foreign matter, the dust container having an inlet port formed at one side of the dust container and an exhaust port formed at the other side;

a motor assembly disposed in the body to generate suction force;

a power supply device to supply power to drive the motor assembly; and

a separate assistant driving unit coupled to the dust container to generate suction force when the dust container is detached from the body.

2. The vacuum cleaner according to claim 1, further comprising:

an assistant hose coupled to the inlet port of the dust container to allow exterior air and foreign matter to be drawn into the dust container through the assistant hose.

3. The vacuum cleaner according to claim 1, wherein the assistant driving unit comprises:

an assistant case having a suction hole formed at one side of the assistant case;

an assistant motor assembly disposed in the assistant case to generate suction force; and

an assistant power supply device to supply power to drive the assistant motor assembly.

4. The vacuum cleaner according to claim 3, wherein the suction hole is formed in the assistant case to be located near the exhaust port of the dust container when the assistant driving unit is coupled to the dust container.

5. The vacuum cleaner according to claim 3, wherein the assistant power supply device is a power cable to be plugged into a wall socket.

6. The vacuum cleaner according to claim 3, wherein the assistant power supply device is a rechargeable battery.

7. The vacuum cleaner according to claim 1, wherein the filter is disposed near the inlet port of the dust container.

8. The vacuum cleaner according to claim 1, wherein the filter is disposed near the exhaust port of the dust container.

9. The vacuum cleaner according to claim 1, wherein the dust container further includes a knob formed at an upper side of the dust container.

10. A vacuum cleaner with an integrated handheld vacuum cleaner unit, comprising:

a body having a hose attaching part and an accommodation part opened partially;

a dust container detachably mounted on the accommodation part and including a filter disposed in the dust container to collect foreign matter, the dust container having an inlet port formed at one side of the dust container and an exhaust port formed at the other side;

a motor assembly disposed in the body to generate suction force;

a power supply device to supply power to drive the motor assembly; and

a separate assistant driving unit coupled to the dust container to generate suction force when the dust container is detached from the body,

wherein, when the dust container is mounted on the accommodation part of the body, the assistant driving unit is seated in a space between a bottom surface of the accommodation part and a lower surface of the dust container.

11. The vacuum cleaner according to claim 10, further comprising:

an assistant hose coupled to the inlet port of the dust container to allow exterior air and foreign matter to be drawn into the dust container through the assistant hose.

12. The vacuum cleaner according to claim 10, wherein the assistant driving unit comprises:

an assistant case having a suction hole formed at one side of the assistant case;

an assistant motor assembly disposed in the assistant case to generate suction force; and

an assistant power supply device to supply power to drive the assistant motor assembly.

13. The vacuum cleaner according to claim 12, wherein, when inserted and mounted on the accommodation part of the body, the assistant driving unit and the dust container are in a state of being coupled by a coupling member.

14. The vacuum cleaner according to claim 13, wherein the coupling member is a hinge allowing rotation of the assistant driving unit and the dust container with respect to each other around the hinge.

15. The vacuum cleaner according to claim 12, wherein the suction hole is formed in the assistant case to be located near the exhaust port of the dust container when the assistant driving unit is coupled to the dust container.

16. The vacuum cleaner according to claim 12, wherein the assistant power supply device is a power cable to be plugged into a wall socket.

17. The vacuum cleaner according to claim 12, wherein the assistant power supply device is a rechargeable battery.

18. The vacuum cleaner according to claim 17, wherein the rechargeable battery is disposed in the assistant case and charged by the power supply device connected to the battery.

19. The vacuum cleaner according to claim 10, wherein the filter is disposed near the inlet port of the dust container.

20. The vacuum cleaner according to claim 10, wherein the filter is disposed near the exhaust port of the dust container.

21. The vacuum cleaner according to claim 10, wherein the dust container further includes a knob formed at an upper side of the dust container.
