Abstract

PROBLEM TO BE SOLVED: To reduce power dissipation by providing a switching means for driving a controller for controlling a heating means by a back-up power source to intermittently supply power to a connecting route of the back-up power source to a material-to-be-heated sensing means. SOLUTION: In the case of presence of supply of power from an AC power source 3 to a controller 2, a power source 5 for driving the controller 2 is connected to the controller 2. On the other hand, in the case of no supply of power from the power source 3 to the controller 2, a back-up power source 6 for driving the controller 2 is connected. Further, a temperature sensing means 7 and a material-to-be-heated sensing means 8 is connected to the controller 2, and a switching means 9 for turning ON, OFF according to a signal from the controller 2 is connected to a connecting route of the means 8 to the power source 6. Only at the time of needing the means 9, the means 9 is turned ON to intermittently supply the power from the power source 6 of the means 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking appliance, and more particularly to a cooking appliance having a backup power supply.

[0002]

2. Description of the Related Art In a conventional cooking device of this type, as shown in FIG. 2, a switching means 4 for turning on / off the supply of electric power from an AC power supply 3 by a signal from a control unit 2 is connected to a heating means 1. Have been. The control unit 2 includes an AC power supply 3.
A power supply unit 5 that drives the control unit 2 when power is supplied from the power supply unit is connected to the power supply unit 5. Further, a backup power supply 6 that drives the control unit 2 when power is not supplied from the AC power supply 3 is connected to the control unit 2. It is connected. Further, a temperature detecting means 7 is connected to the control unit 2. Further, a heated object detection means 8 is connected to the control unit 2. The backup power supply 6 is also connected to the heated object detection means 8.

[0003]

However, in the conventional cooking device, even when power is not supplied from the AC power supply, the power is always supplied to the object-to-be-heated detecting means, and the power consumption increases. There is a problem that the capacity of the backup power supply is increased.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a heating unit for heating food, a control unit for controlling the heating unit, a power supply unit for driving the control unit, When power is not supplied to the power supply unit, a backup power supply that drives the control unit, a temperature detection unit connected to the control unit, and a heated object detection unit for determining the presence or absence of a heated object, The heating target detecting means is provided in a connection path with the backup power supply, and is provided with a switching means for intermittently supplying power.

[0005] According to the invention, power is supplied to the heated object detection means only intermittently by the switching means, so that power consumption is reduced and the capacity of the backup power supply can be reduced.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a heating means for heating food, a control section for controlling the heating means, a power supply section for driving the control section, and a case where power is not supplied to the power supply section. A backup power supply that drives the control unit, a temperature detection unit connected to the control unit, a heated object detection unit for determining the presence or absence of a heated object, the heated object detection unit, A switching unit that is provided on a connection path with the backup power supply and supplies power intermittently.

Since the power is supplied only intermittently to the heated object detection means by the switching means, the power consumption is reduced and the capacity of the backup power supply can be reduced.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a cooking device according to this embodiment. In the figure, a switching unit 4 for turning on / off the supply of electric power from an AC power supply 3 by a signal from a control unit 2 is connected to a heating unit 1. Control unit 2
Control unit 2 when power is supplied from AC power supply 3
And a backup power supply 6 for driving the control unit 2 when power is not supplied from the AC power supply 3 to the control unit 2. Further, a temperature detecting means 7 is connected to the control unit 2. Further, a heated object detection means 8 is connected to the control unit 2. A switching unit 9 that is turned on / off by a signal from the control unit 2 is connected to a connection path between the object-to-be-heated detecting unit 8 and the backup power supply 6.

Next, the operation and function will be described. When no power is supplied from the AC power supply 3, the control unit 2 turns on the switching means 9 only when necessary, Since power is intermittently supplied, power consumption can be reduced.

[0011]

As described above, according to the present invention, even when power is not supplied from an AC power supply, power is supplied only intermittently to the object-to-be-heated detecting means, so that power consumption is reduced. It has a great effect.

Further, since the power consumption is reduced, the capacity of the backup power supply can be further reduced if the same amount of time is backed up.
