1. A vacuum-breaking valve for refrigeration appliances having a cabinet (G) closed by a respective door and refrigerated by a refrigeration system provided with a compressor (C), characterized in that it comprises: a tubular body (10) made of a thermally conductive material and mounted through one of the walls of the cabinet (G), in order to present an inner end (11), which is open to the inside of cabinet (G), and an outer end, (12), which is open to the outside of cabinet (G); a valve seat (30) mounted to the tubular body (10), in order to define a fluid communication between the inside and the outside of cabinet (G); a sealing means (40) mounted to the tubular body (10) and constantly biased towards a closed position, in which it is seated on said valve seat (30), blocking the fluid communication between the inside and the outside of cabinet (G), and movable towards an open position, spaced from the valve seat (30) and which is achieved when the pressure inside cabinet (G) is lower than the pressure outside said cabinet (G); and a heat collector (20) provided with a thermal radiation collecting surface (21) and mounted around the tubular body (10) adjacent to its outer end (12), so that said surface faces a heat source external to the cabinet (G). 2. Valve, according to claim 1, characterized in that the heat collector (20) has its thermal radiation collecting surface (21) facing the compressor (C). 3. Valve, according to claim 2, characterized in that the heat collector (20) has its thermal radiation collecting surface (21) defined by one of the flat or concave surfaces. 4. Valve, according to claim 3, characterized in that the heat collector (20) has the shape of a flange extending from the outer end (12) of the tubular body (10). 5. Valve, according to claim 4, characterized in that the heat collector (20) has the shape of an annular flange mounted around the tubular body (10). 6. Valve, according to claim 5, characterized in that the annular flange is concentric with the tubular body (10). 7. Valve, according to claim 1, characterized in that the heat collector (20) has a surface to be seated against said cabinet wall, opposite to its thermal radiation collecting surface (21). 8. Valve, according to claim 1, characterized in that the tubular body (10) carries a front portion (50) inferiorly defining the valve seat (20) and inside which the sealing means (40) is mounted. 9. Valve, according to claim 8, characterized in that the tubular body (10) is metallic and incorporates the front portion (50). 10. Valve, according to claim 1, characterized in that the thermal radiation collecting surface (21) is provided with a thermally absorbent layer. 11. Valve, according to claim 1, characterized in that the sealing means (40) is a body floating inside the front portion (50) and being constantly and gravitationally biased towards its closed position. 12. Valve, according to claim 11, characterized in that the sealing means (40) is a substantially spherical body, with the valve seat (30) being defined by a narrowing of a lower end (51) of the front portion (50).
