Robot for cleaning swimming pool includes suction head and unstable valve causing intermittent action to move robot through pool

摘要

The robot for automatic swimming pool cleaning comprises a body (1) terminated by a suction head (2). An unstable valve (3) is mounted in the body, and a suction tube (4) has one end (41) connected to the suction head via the unstable valve. The second end (42) of the suction tube includes a section (40) which is subject to depression. The unstable valve is moved by the depression and puts the suction head discontinuously in contact with the depression source (5). The depression may be created by a Venturi device includes a nozzle (52) connected to a pressurized water source (7). The upper end of the suction tube (42) is connected to a recovery filter (6) which comprises a balloon shape attached to the tube. The intermittent action of the unstable valve in response to the depression causes the robot to move across along the swimming pool.
