A method for controlling evaporator defrost in a refrigeration appliance having a cooling circuit with a variable cooling capacity compressor is disclosed. The method includes assessing the cooling capacity of the cooling circuit and calculating the defrost time on the basis of such cooling capacity. Defrost time is preferably assessed on the basis of the inverter frequency driving the compressor and/or the percentage of insertion of the compressor.

A method for controlling power supply to the liquid contents of a cooking vessel or the like, particularly for controlling the electrical power supply in an induction heating system, wherein a predetermined thermodynamic state is detected and the user is alerted, comprises maintaining a predetermined high power condition after reaching the predetermined thermodynamic state for a predetermined time and then reducing the power supply to a predetermined level.

Method for controlling power supply to the liquid contents of a cooking vessel

A method for controlling an inductive heating system of a cooking hob provided with an induction coil is disclosed. The method controls it in connection with a predetermined working condition, comprises assessing the value of power absorbed by the system, measuring a temperature indicative of the thermal status of at least one element of the heating system, feeding the assessed power value to a computing model capable of providing an estimated value of temperature, comparing the measured temperature with the estimated temperature and tuning the computing model on the basis of such comparison.

A method for controlling an induction heating system of a cooking appliance provided with an induction coil, particularly for controlling it in connection with a predetermined working condition, comprises measuring the value of one electrical parameter of the induction heating system, feeding a computing model with actual switching frequency signals in order to estimate a temperature indicative of the thermal status of the heating system and to provide an estimated value of the electrical parameter, and comparing the measured electrical parameter with the estimated one and tuning the computing model on the basis of such comparison.

Method for controlling an induction heating system of a cooking appliance

A method for detecting and compensating the effects of disturbances in controlling induction heating systems by monitoring the temperature of the cooking vessel or its content on the basis of at least one electrical measurement correlated to said temperature. An analysis in time and/or frequency domain of said electrical measurement is carried out in order to detect and compensate the effect of cooking vessel movements and/or mains line voltage fluctuation or similar electrical noises.

Method for detecting and compensating noises in induction heating systems for domestic and professional kitchen and induction heating system using such method

A method for automatically controlling the heating/cooking of a food item in a cooking oven having a door, heaters and an oven temperature acquisition system, comprising the steps of measuring the total electrical power (P) absorbed by the oven, measuring the oven temperature, and assessing the actual power (P) transferred to the food item by automatically compensating disturbance factors. A cooking oven is also disclosed.
