Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic cooker in which high frequency power is supplied to a heating coil by an inverter, and the pan on the heating coil is induction-heated by the high frequency power.

[0002]

2. Description of the Related Art There is no known cooking device provided with data communication means for exchanging data between an external device such as a personal computer and an Internet terminal and an electromagnetic cooking device.
Conventionally, operations such as operation and stop of the cooking appliance, display of operation values during operation of the cooking appliance, and the like have been performed by an operation incorporated in the electromagnetic cooking appliance, a display panel, and the like.

[0003]

The electromagnetic cooker is installed in a home kitchen because it is safe because there is no high temperature part such as a flame or a heater, and there is no air contamination due to combustion such as gas heating. Is getting more and more.

[0004] In addition, the spread of personal computers in recent years, an increase in the number of Internet users, such as connection to the Internet via the personal computers, and connection to the Internet through mobile phones,
Due to changes in the housewife's life rhythm, it is desired that each device has a function of operating a personal computer at home or a device installed in the home from a distance.

[0005]

According to a first aspect of the present invention, there is provided an electromagnetic cooker in which high frequency power is supplied to a heating coil by an inverter, and the pan on the heating coil is induction-heated by the high frequency power. Data communication means for exchanging desired data with the electromagnetic cooker is provided.

According to a second aspect of the present invention, in the electromagnetic cooker according to the first aspect, data from the external device to the electromagnetic cooker includes an operation command, an operation time, a stop command, or a command for the electromagnetic cooker. It is characterized by being at least one of the operation start time, the operation stop time, and the heating power or heating power pattern for the pan.

Further, a third invention is the electromagnetic cooker according to the first invention, wherein the data from the electromagnetic cooker to an external device includes an operation value during operation of the electromagnetic cooker or an internal value of the cooker. It is characterized by at least one of a set value, an operation value immediately before the stop of the cooking device, a failure history of the cooking device, and an integrated operation time of the cooking device.

According to the present invention, since the electromagnetic cooker is provided with the data communication means, it is possible to operate and monitor the electromagnetic cooker from outside or from a distance.

1 is a circuit diagram of an electromagnetic cooker according to an embodiment of the present invention.
Is a pot induction-heated by the electromagnetic cooker 1, and 3 is a personal computer connected to the Internet or a simple personal computer.

The electromagnetic cooker 1 has a DC power supply 11 such as a rectified power supply, and a voltage of the DC power supply 1 as an input voltage.
An inverter 12 having an antiparallel circuit of a T and a diode as an upper and lower arm, a heating coil 13 having one end connected to an AC output point of the inverter 12, and a power supply unit including resonance capacitors 14 and 15; Control circuit 21
An operation for displaying the operation of the power supply unit and the operation state of the power supply unit via the control circuit 21; a display panel 22; an internal set value of the electromagnetic cooker 1, an operation value immediately before stop of the failure, a failure history, A storage circuit 23 for storing the accumulated operation time and the like;
A data communication unit 24 for exchanging desired data between the electromagnetic cooker 1 and the external device 3 is provided.

Since the power supply, the control circuit 21, the data communication means 24, and the like shown in FIG. 1 are constructed by a known technique, detailed description of the detailed operation and circuit configuration will be omitted.

According to the electromagnetic cooker 1 shown in FIG. 1, the conventional electromagnetic cooker can be operated by a built-in operation, a command from a display panel 22 and a set value, and has a data communication means 24. Thereby, the operation of the electromagnetic cooker 1 according to the command and the set value from the external device 3 becomes possible. For example, the operation of the electromagnetic cooker 1 becomes possible from a mobile phone while going out.

Also, since the heating time, heating power value, heating power pattern, and the like by the cooking method obtained via the personal computer and the Internet can be directly set from the personal computer, a memo is taken and the operation is set from the display panel 22. Work can be omitted.

Further, the operation value during operation of the electromagnetic cooker 1 can be displayed as an external device 3 on, for example, a screen of a personal computer.
Since the storage circuit 23 stores the current failure and the past failure history, these are stored in the control circuit 21 and the data communication unit 2.
By displaying on the personal computer screen through 4 and
The cause of the current failure can be easily determined, and the maintenance company can confirm the operating value immediately before the failure stop, the current and past failure histories, and the cumulative operation time of the electromagnetic cooker via the Internet, a telephone line, or the like. In addition, it is possible to confirm the replacement time of the replacement part or the finite life part due to the failure.

[0015]

The electromagnetic cooker of the present invention can meet the needs of society in recent years, and is particularly safe and pollution-free. Can be expected.
