An improvement in the forced air flow system for refrigerators, comprising: at least two refrigeration environments ( ); and a refrigeration air impelling means ( ) forcing the passage of an air flow from a refrigeration environment ( ) through a respective evaporator portion ( ) and comprising only one fan ( ) associated with at least two suction chambers ( ), which are each opened to a respective refrigeration environment ( ) and to at least two discharge chambers ( ), which are each opened to an inlet side ( ) of a respective evaporator portion ( ).

Forced air flow system for refrigerators

A vacuum-breaking valve for refrigeration appliances, comprising: a tubular body ( ) made of a thermally conductive material and mounted through one of the walls of a cabinet (G) of the refrigeration appliance; a valve seat ( ) mounted to the tubular body ( ); a sealing means ( ) constantly biased towards a closed position, in which it is seated on said valve seat ( ), and movable towards an open position when the pressure inside cabinet (G) is lower than the pressure outside said cabinet (G); and a heat collector ( ) provided with a thermal radiation collecting surface ( ) mounted to the tubular body ( ) and facing a heat source external to cabinet (G).

Vacuum-breaking valve for refrigeration appliances

An automatic defrost system for a refrigerating device, comprising, in a cabinet, an evaporator and a condenser, and a defrost air circuit having: a first circuit portion; a second circuit portion receiving a certain defrost airflow from the first circuit portion and positioned adjacent to the condenser, in order to be heated by the latter; a third circuit portion, which is positioned adjacent to the evaporator, so as to selectively heat it when the heated defrost airflow passes through the second circuit portion and to conduct the defrost airflow to the first circuit portion; and a valve means, which selectively permits the passage of the defrost airflow from the second circuit portion to the third circuit portion.
