Abstract

A vacuum cleaner includes a cleaner body capable of standing and inclining, an electric blower accommodated in the cleaner body, a floor nozzle capable of cleaning a surface while the cleaner body inclines, a mode detector detecting whether the cleaner body stands or inclines, and a controller controlling a power supplied to the electric blower. The controller is operable to supply a first power the electric blower if the mode detector detects that the cleaner body inclines, and to supply a second power lower than the first power to the electric blower if the mode detector detects that the cleaner body stands. This vacuum cleaner prevents the electric blower from overheating.

Claims

1. A vacuum cleaner comprising:

a cleaner body;

an electric blower accommodated in the cleaner body;

a floor nozzle provided on a bottom of the cleaner body;

a hose detachably attached to the floor nozzle, the hose allowing the cleaner body to communicate with the floor nozzle;

a hose detector detecting whether or not the hose is attached to the floor nozzle; and

a controller operable to

supply a first power to the electric blower if the hose detector detects that the hose is attached to the floor nozzle, and

supply a second power higher than the first power if the hose detector detects that the hose is detached from the floor nozzle and the mode detector detects that the cleaner body stands.

2. The vacuum cleaner according to claim 1, further comprising a suction-power setting section capable of setting the second power.

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

an attachment adapted to be detachably attached to the cleaner body and additionally detachably attached to a tip of the hose; and

an attachment detector detecting whether or not the attachment is attached to the cleaner body,

wherein the controller changes a power supplied to the electric blower according to a detection result of the attachment detector.

4. A vacuum cleaner comprising:

a cleaner body;

an electric blower accommodated in the cleaner body;

a hose connected to the cleaner body, the hose having a tip;

a plurality of attachments adapted to be detachably attached to the cleaner body and detachably attached to the tip of the hose;

an attachment discriminator determining an attachment detached from the cleaner body out of the plurality of attachments; and

a controller operable to supply a power to the electric blower corresponding to the determined attachment.

5. The vacuum cleaner according to claim 4, wherein the attachment discriminator includes a plurality of attachment detectors detecting whether or not the plurality of attachments are attached to the cleaner body, respectively.

6. The vacuum cleaner according to claim 4, further comprising:

a floor nozzle pivotably attached to a bottom of the cleaner body, the floor nozzle adapted to detachably connected with the tip of the hose;

a hose detector provided at the floor nozzle, the hose detector detecting whether or not the hose is connected with the floor nozzle,

wherein the controller operable to

supply the power to the electric blower corresponding to the determined attachment if the hose detector detects that the hose is detached from the floor nozzle, and

supply the power to the electric blower regardless of a detection result of the attachment discriminator.

7. The vacuum cleaner according to claim 4, wherein

the plurality of attachments include an extension pipe, and

the controller is operable to

supply a first power to the electric blower if the determined attachment is not the extension pipe, and

supply a second power higher than the first power if the determined attachment is the extension pipe.

8. The vacuum cleaner according to claim 4, wherein

the plurality of attachments include a crevice nozzle, and

the controller is operable to

supply a first power to the electric blower if the determined attachment is not the crevice nozzle, and

supply a second power lower than the first power if the determined attachment is the crevice nozzle.

9. The vacuum cleaner according to claim 4, further comprising

a suction-power setting section allowing a user to set the power supplied to the electric blower,

wherein the controller operable to

supply the set power to the electric blower if the hose detector detects that the hose is detached from the floor nozzle, and

supply the power regardless of the set power if the hose detector detects that the hose is attached to the floor nozzle.

10. The vacuum cleaner according to claim 9, further comprising an input indicator indicating an indication corresponding to the set power.

11. The vacuum cleaner according to claim 4, further comprising an attachment indicator indicating an indication corresponding to the determined attachment.

12. A vacuum cleaner comprising:

a cleaner body;

an electric blower accommodated in the cleaner body;

a hose connected the cleaner body, the hose having a tip;

a first attachment adapted to be detachably attached to the cleaner body and detachably attached to the tip of the hose;

a first attachment detector detecting whether or not the first attachment is attached to the cleaner body; and

a controller operable to supply a power to the electric blower according to a detection result of the first attachment detector.

13. The vacuum cleaner according to claim 12, further comprising:

a floor nozzle pivotably attached to a bottom of the cleaner body, the floor nozzle being adapted to detachably connected with the tip of the hose; and

a hose detector provided at the floor nozzle, the hose detector detecting whether or not the hose is connected to the floor nozzle,

wherein the controller operable to

supply a power to electric blower according to the detection result of the first attachment detector if the hose detector detects that the hose is detached from the floor nozzle, and

supply a power regardless of the detection result of the first attachment detector if the hose detector detects that the hose is attached from the floor nozzle.

14. The vacuum cleaner according to claim 12,

wherein the first attachment is an extension pipe, and

wherein the controller operable to

supply a first power to the electric blower if the first attachment detector detects that the extension pipe is attached to the cleaner body, and

supply a second power higher than the first power to the electric blower if the first attachment detector detects that the extension pipe is detached from the cleaner body.

15. The vacuum cleaner according to claim 12,

wherein the first attachment is a crevice nozzle, and

wherein the controller operable to

supply a first power to the electric blower if the first attachment detector detects that the crevice nozzle is attached to the cleaner body, and

supply a second power lower than the first power if the first attachment detector detects that the crevice nozzle is detached from the cleaner body.

16. The vacuum cleaner according to claim 12, further comprising

a suction-power setting section allowing a user sets the power supplied to the electric blower,

wherein the controller operable to

supply the set power to the electric blower if the hose detector detects that the hose is detached from the floor nozzle, and
