Beschreibung
Zusammenfassung:	A cooling appliance includes a cabinet, first and second doors connected to the cabinet and a door-opening detection device having a magnetic element disposed on the first door and a magnetic sensitive element disposed on the cabinet. A first magnetic conductive element on the second door can be magnetized by the magnetic element. The magnetic sensitive element can produce a door-opening signal based on a magnetic field of the first magnetic conductive element. The magnetic sensitive element produces the door-opening signal when at least one of the doors is open. In this way it can be detected, by using one suite of door-opening detection devices, if any door among multiple doors is in an open state. The structure is simple, and the number of components can be reduced. Moreover, wires are reduced, which lowers manufacturing costs and difficulty.
