Abstract

A tilt detectable automatically-operating cleaner includes a tilt detecting unit detecting a tilting state of a main body of the cleaner, a control unit calculating a tilting angle using a detected signal from the tilt detecting unit and determining if the main body tilts by comparing the tilting angle with a reference angle, a driving unit stopping driving of the cleaner when it is determined by the control unit that the main body tilts, and a suction unit controlling suction operation when it is determined by the control unit that the main body tilts

Claims

1. A tilt detectable automatically-operating cleaner comprising:

a tilt detecting unit detecting a tilting state of a main body of the cleaner;

a control unit calculating a tilting angle using a detected signal from the tilt detecting unit and determining if the main body tilts by comparing the tilting angle with a reference angle;

a driving unit stopping driving of the cleaner when it is determined by the control unit that the main body tilts; and

a suction unit controlling suction operation when it is determined by the control unit that the main body tilts.

2. The tilt detectable automatically-operating cleaner of claim 1, further comprising an alarming unit outputting alarm when it is determined by the control unit that the main body tilts.

3. The tilt detectable automatically-operating cleaner of claim 1, further comprising an obstacle detecting unit performing obstacle detection in accordance with the control of the control unit and stopping the obstacle detection when it is determined that the main body tilts.

4. The tilt detectable automatically-operating cleaner of claim 1, further comprising a manipulation unit for selecting operation starting/stopping of the cleaner.

5. The tilt detectable automatically-operating cleaner of claim 4, wherein, during an operation stopping control by determination of the tilt of the main body, the control unit controls operation starting when an operation start command is input from the manipulation unit.

6. A method of controlling a tilt detectable automatically-operating cleaner, comprising:

starting operation of the cleaner;

detecting primarily a tilting angle of a main body of the cleaner;

comparing the detected tilting angle with a reference angle;

performing again the detection of the tilting angle when the detected tilting angle is less than the reference angle and stopping operation of the cleaner when the detected tilting angle is greater than the reference angle; and

detecting secondly a tilting angle of the main body of the cleaner after the cleaner stops operating;

comparing the secondly detected tilting angle with the reference angle; and

maintaining a stopping state of the cleaner when the secondly detected tilting angle is greater than the reference angle and restarting the operation of the cleaner when the secondly detected tilting angle is less than the reference angle.

7. The method of claim 6, further comprising outputting alarm when it is determined that the main body of the cleaner tilts.

8. The method of claim 6, further comprising, after restarting the operation of the cleaner, determining if there is an operation ending command of the cleaner, performing the primary detection of the tilting angle when there is no operation ending command, and ending the operation of the cleaner when there is the operation ending command.

9. The method of claim 6, further comprising, after stopping the operation of the cleaner, determining if there is a forced operation start command, restarting the operation of the cleaner when there is the forced operation start command, and performing the second detection of the tilting angle where there is no forced operation start command.
