  That is, the failure detector 2c detects whether or not the first heater 6a and the second heater 6b are operable, and outputs each detection result to the control unit 2A.

  Based on the temperature data input from the food temperature detector 2a, the operation availability data input from the failure detector 2c, and the data and program stored in its own memory, the control unit 2A 6a, the second heater 6b, the first switch 7a, the second switch 7b, and the power switch 8 are driven.

  That is, when one of the operation availability data of the first heater 6a and the second heater 6b input from the failure detector 2c is inoperable when the PET bottle beverage A is heated, for example, the second heater 6b fails. When the control unit 2 closes the first switch 7a, power is supplied from the power storage unit 5 to the first heater 6a. Thereby, when one of the first heater 6a and the second heater 6b is inoperable, the plastic bottle beverage A is heated by the other, so that both the first heater 6a and the second heater 6b operate. Unless it becomes impossible, the plastic bottle drink A is heated.

  Thus, according to the food heating apparatus of this embodiment, since the plastic bottle drink A can be simultaneously heated by both the first heater 6a and the second heater 6b, the capacity of the commercial AC power source 3 is increased. Without increasing the heating capacity, the plastic bottle beverage A can be heated in a short time, and the plastic bottle beverage A can be used unless both the first heater 6a and the second heater 6b become inoperable. Therefore, it is possible to prevent the operating rate from being lowered due to the inoperability of the heating means.

Based on this, the first heater 6a, the second heater 6b, the first selection switch 9a, the second selection switch 9b, and the power source switch 8 are driven.

  That is, when heating the plastic bottle beverage A, after storing the plastic bottle beverage A in the cylinder 6c and setting the lid 6f, the control unit 2B sets the power switch 8 to the upper side as shown by a two-dot chain line in FIG. For example, the first selection switch 9a is connected to the power storage unit 5 side (left side) as shown by the one-dot chain line in FIG. 6, and the second selection switch 9b is commercialized as shown by the two-dot chain line in FIG. By connecting to the AC power source 3 side (right side), power is supplied from the power storage unit 5 to the first heater 6a, and power is supplied from the commercial AC power source 3 to the second heater 6b. Thereby, since the electric power stored in the electric storage unit 5 is supplied to the first heater 6a and the electric power of the commercial AC power supply 3 is supplied to the second heater 6b, the first heater 6a and the second heater In both cases 6b, the plastic bottle drink A is heated at the same time.

  When one of the operation availability data of the first heater 6a and the second heater 6b input from the failure detector 2c is inoperable when the plastic bottle beverage A is heated, for example, the first heater 6a fails. When the control unit 2B compares the power of the power storage unit 5 and the power of the commercial AC power supply 3 stored in a memory or the like in advance, for example, if the power of the power storage unit 5 is large, the second selection switch 9b is displayed. By connecting to the power storage unit 5 side (left side) as indicated by a one-dot chain line 6, the power stored in the power storage unit 5 is supplied to the second heater 6 b. Thereby, when one of the first heater 6a and the second heater 6b is inoperable, power is supplied to the other from the larger power, so both the first heater 6a and the second heater 6b Unless the bottle becomes inoperable, the plastic bottle beverage A is heated and the heating capacity can be further increased.

  Thus, according to the food heating apparatus of this embodiment, since the plastic bottle drink A can be simultaneously heated by both the first heater 6a and the second heater 6b, the capacity of the commercial AC power source 3 is increased. Without increasing the heating capacity, the plastic bottle beverage A can be heated in a short time, and the plastic bottle beverage A can be used unless both the first heater 6a and the second heater 6b become inoperable. Since the heating capacity can be increased, it is possible to prevent a reduction in the operating rate due to the inoperability of the heating means, and even when some of the inoperability is not possible, the PET bottle beverage can be shortened in a shorter time.
