Abstract

A complex type cleaner is provided. The complex type cleaner includes a body having either a dust collecting container that stores dust or a water collecting container that stores contaminated water, a fan motor installed in the body that generates a suction force, a suction head arranged at a lower side of the body, that sucks dust at a time of performing a vacuum cleaning operation, a water tank mounted adjacent the suction head, that stores cleaning water to be sprayed onto a region to be cleaned at a time of performing a water cleaning operation, and a suction nozzle integrally formed with the water tank, that sucks water contaminated after completing the water cleaning operation. The complex type cleaner so configured reduces a number of components, reduces a fabrication cost, and has a large capacity water tank.

Claims

1. A complex type cleaner;

comprising;

a body having either a dust collecting container that stores dust or a water collecting container that stores contaminated water;

a fan motor installed in the body that generates a suction force;

a suction head arranged on a lower side of the body, that sucks dust into the body at a time of performing a vacuum cleaning;

a water tank mounted adjacent the suction head, that stores cleaning water to be sprayed onto a region to be cleaned at a time of performing a water cleaning; and

a suction nozzle integrally formed with the water tank, that sucks into the body water contaminated at the time of performing the water cleaning.

2. The complex type cleaner of claim 1, wherein the body comprises a container mounting portion that receives either the dust collecting container or the water collecting container mounted therein and a handgrip at an upper side thereof, wherein a vacuum cleaning switch adjusted at the time of a vacuum cleaning mode and a water cleaning switch adjusted at the time of a water cleaning mode are installed on the handgrip.

3. The complex type cleaner of claim 1, further comprising:

a dust suction opening through which dust is sucked into the body formed on a lower surface of the suction head; and

a suction hose configured to be connected to a rear side of the suction head, the suction hose guiding dust that has been sucked into the dust suction opening to the dust collecting container when the suction hose is connected to the rear side of the suction head.

4. The complex type cleaner of claim 1, further comprising a brush that brushes up dust and foreign materials on the region to be cleaned at the time of a vacuum cleaning mode and that rubs the region to be cleaned onto which cleaning water is sprayed at the time of a water cleaning mode installed in the suction head.

5. The complex type cleaner of claim 1, wherein the water tank is installed on an upper surface of the suction head, and is connected to a cleaning water supplying device that supplies water stored in the water tank to the region to be cleaned.

6. The complex type cleaner of claim 5, wherein the cleaning water supplying device comprises:

a cleaning water supplying hose connected to the water tank, that supplies cleaning water stored in the water tank to the region to be cleaned;

a pump installed on the cleaning water supplying hose, that pumps the cleaning water stored in the water tank; and

a spray nozzle mounted at an end of the cleaning water supplying hose, that sprays the cleaning water pumped by the pump to the region to be cleaned.

7. The complex type cleaner of claim 1, wherein the suction nozzle is integrally formed with an upper surface of the water tank, and a hose connection portion, to which a suction hose that guides contaminated water sucked into the suction nozzle into the water collecting container is connected, is formed at an upper side of the suction nozzle.

8. The complex type cleaner of claim 7, wherein the suction nozzle comprises:

a nozzle portion arranged at a front side of a dust sucking opening, that sucks water therethrough; and

a guide passage portion integrally formed with the nozzle portion, that guides contaminated water sucked into the nozzle portion to the suction hose.

9. The complex type cleaner of claim 1, wherein the complex type cleaner is an upright type vacuum cleaner.

10. A vacuum cleaner, comprising:

a body having one of a dust collecting container or a water collecting container mounted thereon;

a fan motor installed in the body that generates a suction force;

a suction head provided on a lower portion of the body that sucks dust into the body during a vacuum cleaning operation;

a water tank mounted adjacent to the suction head; and

a suction nozzle integrally formed with the water tank, that sucks into the body water contaminated during a water cleaning operation.

11. The vacuum cleaner of claim 10, wherein the body comprises a container mounting portion that receives either the dust collecting container or the water collecting container mounted therein.

12. The vacuum cleaner of claim 10, further comprising a suction hose configured to selectively extend between the container mounting portion in which one of the dust collecting container or the water collecting container is mounted and one of a hose connecting portion of the suction nozzle and a hose connecting portion of the suction nozzle.

13. The vacuum cleaner of claim 10, wherein the body comprises a handgrip at an upper end portion thereof wherein a vacuum cleaning switch for selecting the vacuum cleaning operation and a water cleaning switch for selecting the water cleaning operation are provided on the handgrip.

14. The vacuum cleaner of claim 10, further comprising:

a dust suction opening through which dust is sucked into the body formed on a lower surface of the suction head; and

a suction hose configured to be connected to a rear portion of the suction head, the suction hose being configured to guide dust that has been sucked through the dust suction opening to the dust collecting container.

15. The vacuum cleaner of claim 10, further comprising a brush installed in the suction head that brushes up dust and foreign materials on a region to be cleaned during the vacuum cleaning operation and that rubs the region to be cleaned onto which cleaning water is sprayed during the water cleaning operation.

16. The vacuum cleaner of claim 10, wherein the water tank is installed on an upper surface of the suction head, and is connected to a cleaning water supplying device that supplies water stored in the water tank to the region to be cleaned.

17. The vacuum cleaner of claim 16, wherein the cleaning water supplying device comprises:

a cleaning water supplying hose connected to the water tank, that supplies cleaning water stored in the water tank to the region to be cleaned;

a pump installed on the cleaning water supplying hose, that pumps the cleaning water stored in the water tank; and

a spray nozzle mounted at an end of the cleaning water supplying hose, that sprays the cleaning water pumped by the pump to the region to be cleaned.

18. The vacuum cleaner of claim 10, wherein the suction nozzle is integrally formed with an upper surface of the water tank, and a hose connection portion, to which a suction hose is configured to be connected, that guides contaminated water sucked into the suction nozzle into the water collecting container, is formed at an upper side of the suction nozzle.

19. The vacuum cleaner of claim 18, wherein the suction nozzle comprises:

a nozzle portion arranged at a front side of a dust sucking opening, that sucks water therethrough; and

a guide passage portion integrally formed with the nozzle portion, that guides contaminated water sucked into the nozzle portion to the suction hose.

20. The vacuum cleaner of claim 10, wherein the vacuum cleaner is an upright type vacuum cleaner.
