Robotic vacuum cleaner comprising a sensing handle
View Patent ↗A robotic vacuum cleaner comprising sensor means for detecting physical contact with stationary objects in the environment of the vacuum cleaner. The vacuum cleaner comprises a handle ( 1 ) for carrying the vacuum cleaner by hand ( 3 ). The handle ( 1 ) can be in a second position whereby the handle ( 1 ) is located close to the body ( 4 ) of the vacuum cleaner, whereby the sensor means detect forces exerted on the handle ( 1 ) during operation of the vacuum cleaner.
1. A robotic vacuum cleaner comprising sensor means for detecting physical contact with stationary objects in the environment of the vacuum cleaner, characterized in that the vacuum cleaner comprises a handle ( 1 ) for carrying the vacuum cleaner by hand ( 3 ), which handle ( 1 ) can pivot between a first position whereby the handle ( 1 ) is in a substantial upright position in order to carry the vacuum cleaner, and a second position whereby the handle ( 1 ) is located close to the body ( 4 ) of the vacuum cleaner, whereby said sensor means can detect forces exerted on the handle ( 1 ) when the handle ( 1 ) is in said second position.
2. A robotic vacuum cleaner as claimed in claim 1 , characterized in that the sensor means can detect movements of the handle ( 1 ) when the handle ( 1 ) is in said second position.
3. A robotic vacuum cleaner as claimed in claim 2 , characterized in that the sensor means comprise micro switches ( 16 , 18 ) for detecting movements of the handle ( 1 ).
4. A robotic vacuum cleaner as claimed in claim 3 , characterized in that the micro switches ( 16 , 18 ) are arranged at locations where different movements of the handle ( 1 ) can be measured.
5. A robotic vacuum cleaner as claimed in claim 1 , characterized in that in top view of the vacuum cleaner at least a part of the handle ( 1 ) extends outside the remainder portion ( 4 ) of the vacuum cleaner.
6. A robotic vacuum cleaner as claimed in claim 1 , characterized in that in side view of the vacuum cleaner a part of the handle ( 1 ) forms the highest part of the vacuum cleaner when the handle ( 1 ) is in its second position.
7. A method for controlling the travelling path of a robotic vacuum cleaner, whereby a control signal is generated by sensor means when physical contact between the vacuum cleaner and a stationary object in the environment of the vacuum cleaner is detected by said sensor means, characterized in that the vacuum cleaner comprises a handle ( 1 ) for carrying the vacuum cleaner by hand ( 3 ), which handle ( 1 ) can pivot between a first position whereby the handle ( 1 ) is in a substantial upright position in order to carry the vacuum cleaner, and a second position whereby the handle ( 1 ) is located close to the body ( 4 ) of the vacuum cleaner, whereby said sensor means detect forces exerted on the handle ( 1 ) when the handle ( 1 ) is in said second position.
