Abstract

A composite cooking machine includes a plurality of switches which are connected in series with a plurality of component cooking machines, between a circuit breaker in a home and the component cooking machines, respectively, to selectively supply power to the component cooking machines. A control unit of the composite cooking machine controls the switches so as to supply the power to only one of the component cooking machines, without responding to a key signal for another one of the component cooking machines, where a cooking operation performed by the one component cooking machine has not been completed. Therefore, the composite cooking machine does not allow simultaneous operations of the component cooking machines, and prevents unnecessary operations of the circuit breaker. Accordingly, the reliability of the composite cooking machine is improved.

Claims

1. A composite cooking machine for use in a cooking area, comprising:

component cooking machines which use a common power source of the cooking area;

a power supply unit which individually supplies power to the component cooking machines;

an input unit which receives cooking information; and

a control unit which controls the power supply unit to operate only one of the component cooking machines in response to the cooking information input through the input unit.

2. The composite cooking machine as set forth in claim 1, wherein:

the power supply unit comprises switches which are connected in series with the component cooking machines between the power source and the component cooking machines, respectively, and

the power is supplied through one of the switches corresponding to the one of component cooking machines being operated.

3. The composite cooking machine as set forth in claim 1, further comprising a circuit breaker which shuts off the power in response to a flow of a current greater than an allowable current through the circuit breaker, wherein the power supply unit supplies the power supplied through the circuit breaker to the corresponding one of the component cooking machines.

4. The composite cooking machine as set forth in claim 1, wherein the component cooking machines are cooking machines which perform different cooking functions.

5. The composite cooking machine as set forth in claim 4, wherein the component cooking machines are implemented as one group of a microwave oven and a coffee maker, a microwave oven and a toaster, a microwave oven and an electric range, and a microwave oven and an air cleaner.

6. The composite cooking machine as set forth in claim 1, wherein the control unit does not respond to a key signal corresponding to a cooking instruction of the cooking information to operate another one of the component cooking machines in response to a cooking operation performed by the one of the component cooking machines not being completed.

7. The composite cooking machine as set forth in claim 1, wherein the composite cooking machine is a wall-mountable composite cooking machine.

8. The composite cooking machine as set forth in claim 2, further comprising a circuit breaker which shuts off the power in response to a flow of a current greater than an allowable current through the circuit breaker, wherein the power supply unit supplies the power supplied through the circuit breaker to the corresponding one of the component cooking machines.

9. The composite cooking machine as set forth in claim 2, wherein the control unit turns on only the one of the switches corresponding to the component cooking machine being operated at a time so as to prevent the other component cooking machines from operating.

10. A composite cooking machine comprising:

a single power supply unit which supplies power to operate the composite cooking machine;

component cooking machines which share the single power supply unit; and

a control unit which controls the single power supply unit and prevents a simultaneous operation of the component cooking machines by not responding to a signal to operate the other component cooking machines in response to an operation of one of the component cooking machines not being completed.

11. The composite cooking machine as set forth in claim 10, further comprising:

an input unit which receives an operating information to operate the composite cooking machine; and

a circuit breaker which shuts off the power in response to a flow of a current greater than an allowable current of the circuit breaker, wherein the single power supply unit supplies the power supplied through the circuit breaker to the corresponding one of the component cooking machines.

12. The composite cooking machine as set forth in claim 10, wherein:

the single power supply unit comprises switches which are connected in series with the component cooking machines between an external power source and the component cooking machines, respectively, and

the control unit turns on only one of the switches corresponding to the component cooking machine being operated so as to prevent the other component cooking machines from operating.

13. The composite cooking machine as set forth in claim 10, wherein the component cooking machines are cooking machines which perform different cooking functions.

14. The composite cooking machine as set forth in claim 10, wherein the composite cooking machine is a wall-mountable composite cooking machine.

15. A method of controlling a composite cooking machine having a single power supply unit which supplies power to operate the composite cooking machine, component cooking machines which share the single power supply unit, and a control unit which controls the single power supply unit and prevents a simultaneous operation of the component cooking machines, the method comprising:

receiving cooking information to operate the composite cooking machine; and

controlling the single power supply unit to operate only one of the component cooking machines in response to an operation of the one of the component cooking machines not being completed.

16. The method as set forth in claim 15, wherein the controlling of the single power supply unit comprises not responding to a signal to operate another one of the component cooking machines in response to the operation of the one of the component cooking machines not being completed.

17. The method as set forth in claim 15, wherein the controlling of the single power supply unit comprises:

determining the one of the component cooking machines to operate in response to the received cooking information;

supplying the power to the one of the component cooking machines while preventing the remaining component cooking machines from receiving the power;

determining whether a signal to operate another one of the component cooking machines is received; and

operating the another one of the component cooking machines after completing the operation of the one of the component cooking machines.

18. The method as set forth in claim 17, wherein the operating the another one of the component cooking machines includes supplying the power to the another one of the component cooking machines while preventing the remaining component cooking machines from receiving the power until an operation corresponding to the another one of the component cooking machines is completed.
