摘要： An electric appliance (100) is proposed. The electric appliance (100) comprises:
at least one electromechanical device (210 1 ,210 2 ) switchable between activated and deactivated states thereby allowing energization and de-energization, respectively, of at least one electric load (205 1 ,205 2 ) of the electric appliance (100), the electromechanical device (210 1 ,210 2 ) being responsive to a first driving voltage above which it is switched into an activated state, and to a second driving voltage, lower than the first driving voltage, above which the electromechanical device (210 1 ,210 2 ) is held in the activated state,
a switching arrangement (215,220,225 1 ,225 2 ) for switching the electromechanical device (210 1 ,210 2 ) according to a combination between a command signal ( S COMM1 ,S COMM2 ) and a PWM signal, the duty cycle of the PWM signal being such that:
- at a first level of the command signal ( S COMM1 ,S COMM2 ), the PWM signal combined with the command signal ( S COMM1 ,S COMM2 ) results in a driving voltage at the electromechanical device (210 1 ,210 2 ) at least equal to said first driving voltage, and
- at a second level of the command signal ( S COMM1 ,S COMM2 ), the PWM signal combined with the command signal ( S COMM1 ,S COMM2 ) results in a driving voltage at the electromechanical device (210 1 ,210 2 ) between said first and second driving voltages.

摘要： A method ( 300 ) for diagnosing an electric appliance ( 100 ) is proposed. The electric appliance ( 100 ) comprises at least one electromechanical component (205 1 ,205 2 ) each one being switchable between deactivated and activated states. For each selected electromechanical component (205 1 ,205 2 ) the method comprises:
applying ( 310,345 ) to the selected electromechanical component (205 1 ,205 2 ) a PWM signal having a duty cycle whose value is at a reference duty cycle value,
varying ( 315,350 ) the value of duty cycle of the PWM signal from the reference duty cycle value,
sensing ( 320,355 ) the switching of the selected electromechanical component (205 1 ,205 2 ), the value of duty cycle at which the switching of the selected electromechanical component (205 1 ,205 2 ) has been sensed corresponding to an actual minimum driving signal to which the selected electromechanical component (205 1 ,205 2 ) is responsive,
comparing ( 335,370 ) the actual minimum driving signal of the selected electromechanical component (205 1 ,205 2 ) to a respective expected minimum driving signal to which the selected electromechanical component (205 1 ,205 2 ) is expected, by design, to be responsive, and
signaling ( 340,375 ) an error of the selected electro-mechanical component (205 1 ,205 2 ) if ( 335,370 ) the actual minimum driving signal is higher than the respective expected minimum driving signal.

摘要： A laundry treatment appliance (100) is provided. The laundry treatment appliance (100) comprises a cabinet (110) and a drum (107) rotatably accommodated within said cabinet for housing laundry to be treated. The laundry treatment appliance (100) further comprises a permanent split capacitor motor (160) selectively operable to rotate the drum clockwise and counterclockwise. The permanent split capacitor motor is configured to be supplied by a supply voltage provided across a first supply terminal (250) and a second supply terminal (255) of an AC power supply. The permanent split capacitor motor comprises a main terminal (235), a first control terminal (240), and a second control terminal (245). The main terminal is coupled with the first supply terminal. The laundry treatment appliance (100) further comprises a switching apparatus (262, 264, 266, 268) configured to selectively couple:
- the first control terminal with the second supply terminal, while decoupling the second control terminal from the second supply terminal, for rotating the drum clockwise, or
- the second control terminal with the second supply terminal, while decoupling the first control terminal from the second supply terminal, for rotating the drum counterclockwise.
The laundry treatment appliance (100) further comprises a voltage sensing unit (270, 272) configured to sense the voltage at the first control terminal to produce a corresponding first sensed voltage and to sense the voltage at the second control terminal to produce a corresponding second sensed voltage. The laundry treatment appliance (100) further comprises a control unit (280) configured to assess an overload condition of the drum based on:
a) the first sensed voltage when the second control terminal is coupled with the second supply terminal, and
b) the second sensed voltage when the first control terminal is coupled with the second supply terminal.
