PROBLEM TO BE SOLVED: To provide a vehicle-mounted refrigerator-freezer having the structure which can certainly remove the frost attached to the surface of a cooler and is inexpensive.SOLUTION: A vehicle-mounted refrigerator-freezer includes: a freezing chamber 2; a refrigerating chamber 3 which communicates with the freezing chamber 2 through a communication passage 4; a cooler 5 which cools the inside of the freezing chamber 2; a refrigerating chamber fan 7 which blows cold air in the freezing chamber 2 into the refrigerating chamber 3 through the communication passage 4; a heater 8 which removes the frost attached to the surface of the cooler 5; a control unit 15 which controls the energized state of the heater 8; and a temporary defrosting operation unit 22 which is connected to the control unit 15 and performs the operation to energize the heater 8. The control unit 15 includes: a fixed time defrosting timer 17 which stores fixed energizing time for which the heater 8 is energized at a fixed time; and a temporary defrosting timer 18 which stores energizing duration for which the heater 8 is energized by the operation of the temporary defrosting operation unit 22.SELECTED DRAWING: Figure 1
