Abstract: A refrigerator-freezer of the combined type comprises a first and a second refrigerating units and a single cooling circuit for both units, which are fluid-dynamically and reciprocally connected by an air passage conduit; the temperature inside the first unit is controlled by a device comprising motorised interception means of the passage conduit; electronic control means of the motorised interception means, directly carried aboard a supporting body adapted in use to be arranged along the passage conduit; an electronic temperature sensor operatively and directly connected to the electronic control means, carried aboard the supporting body; and ventilator means, carried aboard the supporting body, operated by the electronic control means of the motorised interception means for selectively ensuring circulation of air by forced convection between the first and second refrigerating units along the passage conduit.

Abstract: In an electric refrigeration appliance having at least one refrigeration compartment, a refrigerating arrangement having an evaporator, and a control device that controls the refrigeration compartment temperature and that has a temperature sensor; the temperature sensor is located away from the evaporator and in a portion of a refrigeration compartment volume selected with the exclusion of a first top portion of the refrigeration compartment having a volume equal to roughly 8-10% of the total internal volume of the refrigeration compartment, and with the exclusion of a second front portion of a depth equal to at least 10% of the total inside depth of the refrigeration compartment.

Abstract: A thermostat, in particular for electric household appliances, including a mechanical switch and an analog regulating circuit having a variable-ratio reference divider. The reference divider includes a reference resistor and a variable-resistance resistive element; and the mechanical switch connects the variable-resistance resistive element to the reference resistor.
