WASHING MACHINE OF DRUM TYPE Russian patent published in 2011 - IPC D06F37/26 

FIELD: textile, paper.

SUBSTANCE: washing machine of drum type is patented, in which nozzles are located in tank of washing machine, which act at washed object with a jet of detergent solution via joined holes of drum and nozzle heads. Washing machine is equipped with 2…8 nozzles arranged in a row parallel to axis of drum rotation, working fluid to which is supplied by hydraulic pump fixed on cylindrical surface of tank at two sides symmetrically relative to vertical plane, passing through axis of rotation, at the height equal to 0.5…0.9 of drum diametre. Besides, output holes of nozzles are aligned downwards at the angle of 10°…90° to horizontal line, and some holes on drum, near base of combs, are arranged as oval and located in a row parallel to tops of combs at the distance equal to gap between nozzles so that when drum rotates, heads of drum nozzles and holes in drum are matched for an instance. At the same time washing machine is equipped with sensors of matching of nozzles holes and working holes of perforated drum, output signal from which is sent into control system, which opens heads of nozzles for an instance with account of drum rotation direction.

EFFECT: increased efficiency of washing.
