Publication number: 20210212176Abstract: The present invention relates to a method for controlling a cooking zone (16) of an induction cooking hob, wherein said cooking zone (16) comprises at least one induction coil (16) and is supplied by a generator (14) including a power switch. The method is performed by controlling the power switch by a gate driving signal (18) including a deactivation pulse length (Toff) and an activation pulse length (Ton). A switching period (T) of the gate driving signal (18) is given by the sum of the activation pulse length (Ton) and deactivation pulse length (Toff). A driving frequency (f) of the power switch is the reciprocal value of said switching period (T). The deactivation pulse length (Toff) depends on the resistance (28) and the inductance (30) of the induction coil (16). The activation pulse length (Ton) is varied according to a requested power for the cooking zone (16). A series of constant activation pulse length (Ton) is activated in order to determine the optimal deactivation pulse length (Toff).Type: ApplicationFiled: June 3, 2019Publication date: July 8, 2021Inventors: Frederico BALEST, Laurent JEANNETEAU, Alex VIROLI, Massimo NOSTRO

Patent number: 10584708Abstract: A method for checking functions of fans includes starting a normal operation mode, evaluating a fan monitoring signal depending on the fans' speeds, and starting a dynamic fan checking routine. If the monitoring signal is smaller than a lock threshold value, normal operation proceeds. If the monitoring signal is bigger than the lock threshold value, a multiple-fan checking routine is started. During each fan test the corresponding fan is activated for a predetermined time period, while the other fans are deactivated during the time period, and the monitoring signal is compared with the lock threshold value and a disconnecting threshold value. If the monitoring signal is bigger than the lock threshold value, the corresponding fan is locked and an error is detected. If the monitoring signal is smaller than the disconnecting threshold value, the corresponding fan is disconnected and an error is detected.Type: GrantFiled: February 1, 2016Date of Patent: March 10, 2020Assignee: Electrolux Appliances AktiebolagInventors: Laurent Jeanneteau, Massimo Nostro, Massimo Zangoli, Alex Viroli, Nicola Terracciano

Patent number: 10573476Abstract: Contacts of a relay may glue together during operation. This state may be measured and a controller may issue a pulse width-modulated signal at a certain duty cycle and frequency in order to vibrate the relay contacts to make them open again. Once this is the case, the process is stopped. This process may be repeated a certain number of times, and if successfully degluing is not possible, a notification may be generated. Also after a certain number of degluing cycles, a signal may be generated to indicate replacement of the relay.Type: GrantFiled: July 23, 2015Date of Patent: February 25, 2020Assignee: Electrolux Appliances AktiebolagInventors: Laurent Jeanneteau, Alex Viroli, Massimo Nostro, Fabio Angeli
