  Reference numeral 30 denotes a power supply circuit that generates an operating voltage of a predetermined level and supplies power to each circuit. When power is supplied from 49, the power supply selection circuit is a power supply selection circuit that supplies power from the power supply circuit 49 to the power supply circuit 30 in preference to the dry cell power supply. As the power supply selection circuit 31, a switching circuit using a transistor, a relay, or the like is used to shut off the circuit on the dry cell side when the power supply voltage from the power supply circuit 49 is detected, or from the power supply circuit 49 Various configurations such as switching the switch provided inside by connecting the connection terminals can be adopted.

  On the other hand, the oven 3 includes an oven control circuit 40 including a CPU, a memory, a timer, and the like, and inputs a detection signal from a temperature detection thermistor (TH) provided in the heating chamber 13 to the oven control circuit 40.

In addition, when the operating voltage falls below a predetermined level, the operation of the oven control circuit 40 is stopped, the reset IC circuit 44 that initializes the oven control circuit 40, and the flame of the frame rod (FR) provided in each burner. A flame detection circuit 45 for inputting a current to the oven control circuit 40 and an electromagnetic valve circuit 46 for controlling energization to an electromagnetic valve (MV) provided in a gas supply path to each burner are provided.

  Reference numeral 47 denotes a power supply circuit that generates an operating voltage of a predetermined level from a commercial power supply obtained by the plug 48 and supplies power to each circuit. Between the power supply circuit 47 and the plug 48, the power supply selection circuit 31 of the stove 2 Power supply as a power supply means that is connected and has a well-known transformer, rectifier, etc. on the wiring, converts the commercial power source into a DC power source (e.g., DC 3V) corresponding to a dry cell and supplies it to the power source selection circuit 31 A circuit 49 and a changeover switch 50 capable of manually turning on / off the supply of commercial power to the power supply circuit 49 are provided. The changeover switch 50 is provided, for example, on the operation panel 12 on the built-in stove 2 side or the operation panel 14 on the oven 3 side.

The operation relating to power supply in the built-in stove 1 configured as described above will be described based on the flowchart of FIG.
First, in S1, it is determined whether or not the changeover switch 50 is ON. If the changeover switch 50 is ON, the operation is performed by the oven power supply in S2. That is, since the power supply circuit 49 generates a power source equivalent to a dry cell created from a commercial power source and flows to the power source selection circuit 31 of the built-in stove 2, this power source is supplied to the power circuit 30 and used as the power source of the built-in stove 2. Become.

  On the other hand, if the changeover switch 50 is OFF in the determination in S1, it is determined in S3 whether or not the dry battery 32 is set. If the set of the dry battery 32 is confirmed here, it operates with a dry battery power supply in S4. That is, since there is no power supply from the power supply circuit 49, the power supply selection circuit 31 supplies power from the dry battery 32 to the power supply circuit 30. This process is the same when the plug 48 is not inserted into the outlet on the oven 3 side or when a power failure occurs. Note that the setting of the dry battery 32 in this flow means that the dry battery power supply is confirmed to be equal to or higher than a predetermined voltage (for example, 3 V), and when the voltage is lower than the predetermined voltage, it is determined that the dry battery 32 is not set.

During the operation with the dry battery power source, ON confirmation of the changeover switch 50 in S1 and confirmation of setting of the dry battery 32 in S3 are performed. Therefore, if the changeover switch 50 is ON in the determination of S1, the operation is performed by the oven power supply in S2.
If the dry battery 32 is not set in the determination of S3, the built-in stove 1 is not supplied with power, and thus does not operate (S5). However, if the changeover switch 50 is confirmed to be ON in the subsequent determination of S1, it operates with the oven power supply (S2), and if the set of the dry batteries 32 is confirmed in the determination of S3, it operates with the dry battery power supply (S4). .

  Thus, according to the power supply system of the built-in stove 2 of the said form, the power supply circuit which produces | generates the power supply equivalent to a dry cell from the commercial power supply by the side of the oven 3 which operate | moves with a commercial power supply, and supplies it to the built-in stove 2 as a power supply By providing 49, it is possible to save the trouble of replacing the dry battery, and it is excellent in usability.

In particular, here, the built-in stove 2 is preferentially supplied to the built-in stove 2 with the power from the dry battery 32 and the power supply circuit 49, and when power is not supplied from the power supply circuit 49 to the built-in stove 2. By providing the power source selection circuit 31 for supplying power, the built-in stove 2 can be operated with a dry battery power source when commercial power is not supplied due to a power failure or the like.
Further, by providing the changeover switch 50 for turning on / off the supply of power from the power supply circuit 49 to the built-in stove 2, any power supply can be selected as necessary, and convenience is improved.

In addition, in the said form, although the power supply circuit is provided in the oven side, you may provide in the built-in stove side. Further, without providing a separate power supply circuit, as shown in FIG. 4, the power equivalent to the dry cell created by the power circuit 47 of the oven 3 is supplied to the power selection circuit 31 of the built-in stove 2 via the changeover switch 50. You may do it.
Further, the changeover switch may be omitted in the form of FIGS. 2 and 4 so that the power equivalent to the dry cell is always supplied to the power selection circuit of the built-in stove at the same time when the oven is turned on. In this case, there is no need to operate the changeover switch.
In addition, the Billton stove can be operated only with the power supply from the oven side, omitting the dry cell itself.

  In addition, the electric equipment is not limited to an oven, but can be any other type as long as it operates on a commercial power source such as a range, a combination range, a dishwasher, etc. The cooking device is not limited to a built-in stove, A table stove or the like can be used as long as it operates.
