Abstract

A HEATING APPARATUS SUCH AS MICROWAVE OVENS INCLUDES A HEATING CHAMBER HAVING AN OPENING, A DOOR (22) FOR CLOSING AND OPENING THE OPENING OF THE HEATING CHAMBER, AT LEAST TWO SAFETY SWITCHES (24,25) CONNECTED TO POWER SUPPLY LINES (31, 32) TO BE CAPABLE OF CUTTING OFF BOTH POLES THEREOF RESPECTIVELY, EACH SAFETY SWITCH (24; 25) INCLUDING A PLURALITY OF CONTACTS AND PERFORMING A SWITCHING OPERATION IN RESPONSE TO OPENING AND CLOSING OF THE DOOR (22), A FIRST CONTROL CIRCUIT (35) CONNECTED TO DOOR OPENING CONTACTS FURTHER CONNECTED TO COMMON CONTACTS OF THE SAFETY SWITCHES (24, 25), A DOOR SWITCH (29) FOR DETECTING OPENING AND CLOSING OF THE DOOR (22), AND A SECOND CONTROL CIRCUIT (35) FOR CONTROLLING THE FIRST CONTROL CIRCUIT (35) SO THAT THE FIRST CONTROL CIRCUIT (35) DETECTS FAILURE OF THE SAFETY SWITCHES (24, 25) WHEN THE DOOR (22) IS OPENED. WHETHER AT LEAST ONE OF THE SAFETY SWITCHES (24, 25) HAS FAILED CAN BE DETERMINED ON THE CONDUCTIVE STATE OF THE DOOR OPENING CONTACTS OF THE SAFETY SWITCHES (24, 25).(FIG.1)
