A clothes washing machine including a washing tub containing a drum and a door for closing the drum provided with a door interlock arrangement. The door interlock arrangement includes an electromagnet (1), a main sliding element (4), a door catch (5), a spring (6) forcing said main sliding element back to its resting position, an inclined plane (9) of the door catch, a switch (2) actuated by the main sliding element (4), a device (10) that is electrically energized during spin-extraction phases only, a peg (11) projecting from the device (10) when the latter is not energized, and a recess (12) for accommodating the projecting peg (11) in the main sliding element (4). The main sliding element (4) also includes a recess (8) for accommodating the door catch (5). A secondary sliding element (3) is provided so as to be able to slide transversely with respect to the main sliding element (4). A spring (7) acts upon the secondary sliding element (3), and an upper edge (13) of the main sliding element (4) is capable of cooperating by interference with a downward projection (14) of the secondary sliding element (3).

Door interlock arrangement for washing machines

A controlling device controls the operation of a clothes washing machine having a tub, a washing liquid collector, a heating element and two thermostats within the collector, and an electric pump for circulating the washing liquid from the collector to the tub. Three pressostats or pressure switches allow washing liquid to be filled to two different levels in the machine and for controlling the working condition of a filtering element within the collector. The controlling device allows both 'intensive' washing programs with only a low level of liquid in the collector and 'delicate' washing programs with normal levels of liquid in the tub. Different types of laundry can be washed under the best conditions with low consumption of water, detergents and electric power.
