WATER-BEARING HOUSEHOLD UNIT WITH ELECTRIC DRIVE Russian patent published in 2012 - IPC A47L15/42 

FIELD: personal use articles.

SUBSTANCE: invention relates to an electric drive for water-bearing household appliances. Electric drive for liquid pumps of water-bearing household appliance comprises a controlled converter (2) of AC to obtain power voltage at a multiphase network (6), as well as at least one electric motor (17), which is designed as a synchronous motor with permanent magnet excitation and can be connected to a multiphase network (6) to drive the liquid pump (7). The control unit (10, 11) is used to control the converter (2) of AC to provide the work of the electric motor (17) from three-phase network (6). There is another one electrical device (8, 9), which can be connected to the intermediate circuit (3-1) powered in front of the converter (2), on which the load current passes, and the electrical device comprises at least one electric motor for another liquid pump (8) and/or air-blowing device (20) and/or at least one valve (9).

EFFECT: electric drive is designed, which enables to implement a technically more simple electronic control of drive motor of liquid pump.
