A machine for washing comprises:
- a supply line (AC), which includes a first conductor (N) and a second conductor (L);
- a plurality of electrical loads, which include a heating element (R) and a motor (P) of a pump; and
- a control circuit, which includes:
- a control unit (CU);
- first switching means (DS'), which can be driven by the control unit (CU) for supplying the heating element (R) by connecting it between the first and second conductors (L, N); and
- second switching means (TR), which can be driven by the control unit (CU) for supplying the motor (P) by connecting it between the first and second conductors (L, N).
The control unit (CU) is configured for driving the first switching means (DS') and the second switching means (TR) for supplying the heating element (R) during periods of operation of the machine different from those in which the motor (P) is supplied. The first switching means are constituted by a monostable switch (DS') that can be switched between:
- a first position, in which the motor (P) is connected between the first and second conductors (L, N) through the monostable switch (DS') in said first position and said second switching means (TR); and
- a second position, in which the heating element (R) is connected between the first and second conductors (L, N) through the monostable switch (DS') in said second position. The stable position of the monostable switch (DS') is said first position. |
