First Claim
Patent Images
1. A vacuum cleaner comprising:
- a cleaner body;
a mode detector for detecting whether the cleaner body is inclined or standing;
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 tosupply a first power to the electric blower if the hose detector detects that the hose is attached to the floor nozzle and the mode detector detects that the cleaner body is inclined, andsupply a second power to the electric blower lower than the first power if the mode detector detects that the cleaner body is standing and the hose detector detects that the hose is attached to the floor nozzle;
supply a third power higher than the second power and lower 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 is standing.

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.

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 the detached attachments are each attachable to the tip of the hose; an attachment discriminator determining which one of the plurality of attachments is the attachment detached from the cleaner body; and a controller operable to supply a respectively different power amount to the electric blower corresponding to which one of the attachments is detached from the cleaner body. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

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 the detached first attachment is attachable to the tip of the hose; a first attachment detector detecting whether or not the first attachment is attached to the cleaner body, the first attachment detector is provided inside the cleaner body; and a controller operable to supply a respectively different power amount to the electric blower according to a detection result of the first attachment detector whether or not the first attachment is detached from the cleaner body. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
