Abstract:
A cleaning robot (1) is provided with: a main body housing (2) that moves along a floor in a self-propelled manner with a suction port (6) and an exhaust port (7) open; a motor fan (22) positioned inside the main body housing (2); a dust collection part (30) driven by the motor fan (22) so as to collect airflow dust that has been suctioned from the suction port (6); an infrared remote controller (60) that specifies an arbitrarily-defined location in space for setting up the main body housing (2) by emitting infrared rays; and an infrared sensor (18) that detects the specified location specified by the infrared remote controller (60). The cleaning robot moves to the specified location detected by the infrared sensor (18) and then carries out a cleaning operation, or carries out a cleaning operation while moving to the specified location.

PROBLEM TO BE SOLVED: To provide a self-propelled ion generator that can efficiently spray ions to a location requiring ions.SOLUTION: A cleaning robot 1 of a self-propelled ion generator includes: a main housing that is self-propelled over a floor surface with an opened suction port and an opened exhaust port; an electric blower 22 disposed inside the main housing; an ion generating device 25 for discharging ions in a second exhaust path between the electric blower 22 and the exhaust port; and an environment detection device (an odor sensor 52, a humidity sensor 53, a human sensor 54 and a travel map 18a) for detecting the environment surrounding the main housing. On the basis of the environment surrounding the main housing detected by the environment detection device, the cleaning robot remains at a determined specific location for a fixed time and sends an airflow containing ions from the exhaust port by driving the ion generating device 25 and the electric blower 22.

PROBLEM TO BE SOLVED: To provide a cleaning path guidance method combined with a dirt detection mechanism.SOLUTION: The cleaning path guidance method combined with a dirt detection mechanism is performed in an automatic cleaning device to generate a cleaning path, so as to guide the automatic cleaning device to clean a non-cleaned area, in which plural grids are defined in the non-cleaned area. The method includes: moving the automatic cleaning device in the non-cleaned area to clean dirt away, and continuously detecting a flow of the dirt cleared away to obtain a dirt level of a current gird; if the dirt level of the current gird exceeds a threshold, marking the grid as a dirty grid; performing an algorithm and finding a shortest path passing through all dirty grids as a cleaning path according to the marked dirty grids; and moving the automatic cleaning device to pass through each dirty grid according to the clean path, so as to clean each dirty gird sequentially.
Abstract:
PROBLEM TO BE SOLVED: To provide a cleaning robot to prevent a suction member from moving upwards when the suction member is rotated during a collision with an obstacle, to completely unfold the suction member when the suction member travels on an uneven surface such as a carpet, and further to automatically fold and unfold the suction member. SOLUTION: A torsion spring for connecting an elevating member 44 and a suction member 50 rotates the suction member 50 within a range of elastic deformation, when a suction arm 51 collides with the obstacle, the suction arm is folded toward the body side, and after passing the obstacle, the suction arm 51 is unfolded by elasticity of the torsion spring. A coil spring 49 allows the suction member 50 to move upwards and downwards depending on a change of a height of the surface to be cleaned while the cleaning robot 49 travels on the uneven surface. At this time, a guide knob 45 move upwards together with the elevating member 44, thereby separating from the rotation guide face, and the suction arm 51 can be maintained in a completely unfolded state.
