1 is a block diagram illustrating a cooking apparatus according to an embodiment of the present invention.

1, a cooking apparatus according to an embodiment of the present invention includes a master control unit 11, a slave control unit 13, a switching unit 15, a salt sensing unit 19, And may include a support portion 21.

The salt sensing unit 19 is disposed adjacent to the heat source 17 to sense a flame generated from the heat source 17. [

The heat source 17 may be a source of ignition where heat is generated by gas or electricity.

The salt sensing signal sensed by the salt sensing unit 19 may be provided to the master control unit 11 and the slave control unit 13.

For example, the salt sensing signal sensed by the salt sensing unit 19 may be provided to the master control unit 11 and the slave control unit 13 at the same time.

For example, the salt sensing signal sensed by the salt sensing unit 19 may be selectively provided according to the operation states of the master control unit 11 and the slave control unit 13, respectively.

That is, when the master control unit 11 is normally operated, the salt sensing signal sensed by the salt sensing unit 19 is provided to the master control unit 11, but may not be provided to the slave control unit 13.

When the master control unit 11 is abnormally driven, that is, when the master control unit 11 is inoperable, the salt detection signal sensed by the salt sensing unit 19 is supplied to the slave control unit 13, May not be provided.

The output block sensor 21 can sense an output signal output from the master control unit 11, which is disposed between the master control unit 11 and the switching unit 15, that is, at the output end.

The output sensed signal sensed by the output sensor 21 may be provided to the master control unit 11 and the slave control unit.

For example, an output sensed signal sensed by the output sensor section 21 may be provided to the master control section 11 and the slave control section 13 at the same time.

For example, the output sensed signal sensed by the output sensor section 21 may be selectively provided according to the operation states of the master control section 11 and the slave control section 13, respectively.

That is, when the master control unit 11 is normally driven, the output detection signal sensed by the output edge detection unit 21 is provided to the master control unit 11 but not to the slave control unit 13. [

When the master control unit 11 is abnormally driven, that is, when the master control unit 11 is inoperable, the output detection signal sensed by the output stroke detection unit 21 is supplied to the slave control unit 13, May not be provided.

The switching unit 15 is disposed between the master control unit 11 and the heat source 17 and may be switched in response to an output signal output from the master control unit 11 to supply or block gas or electricity to the heat source 17 .

For example, the switching unit 15 may be turned off in response to an output signal from the master control unit 11 to block gas or electricity supplied to the heat source 17.

For example, the switching unit 15 may be turned on in response to an output signal output from the master control unit 11, and gas or electricity may be supplied to the heat source 17.

In summary, the switching unit 15 can be turned on or off between the heat source 17 and a supply source for supplying gas or electricity.

The master control unit 11 can control the entire heat source 17 as a whole.

For example, the master control unit 11 can detect the state of the heat source 17 and control the supply or cutoff of gas or electricity to the heat source 17 based on the detected state of the heat source 17. [

For example, the master control unit 11 can control the heat source 17 to be operated for a specific time by the timer function.

The slave control unit 13 can perform a control operation similar to the master control unit 11 in cooperation with the master control unit 11. [

Here, the term " interlocking " may mean that it is driven together with the slave controller 13. [ That is, when power is input to the cooking apparatus and the master control unit 11 is driven, the slave control unit 13 can be driven at the same time.

For example, the slave controller 13 can detect the state of the heat source 17 and control the gas source or the electricity to be supplied or blocked to the heat source 17 based on the detected state of the heat source 17.

The slave controller 13 can sense the operation state and the control state of the master controller 11. [ To this end, communication lines are connected between the slave control unit and the master control unit 11, and data or information can be exchanged with each other through the communication line.

For example, the master control unit 11 may periodically provide the slave control unit 13 with status information on the operation state and the control state of the master control unit 11. [

The slave control unit 13 can determine whether the master control unit 11 is operating normally or abnormally based on status information about the operation state or the control state provided from the master control unit 11. [

The status information on the abnormal operation of the master control unit 11 includes malfunction, reset, runaway or partial runaway.

Congestion may mean that it can not escape from all of the many routines being operated for normal control operations.

Partial congestion may mean that the routine can not escape from a particular routine among a plurality of routines being operated for normal control operations.

If congestion or partial congestion occurs as described above, the master control unit 11 becomes inoperable, and both the sensing function, the determination function, the control function, and the output function may become inoperable.

The slave control unit 13 may consider a salt detection signal provided from the salt detection unit 19 or an output detection signal provided from the output edge detection unit 21 when the abnormal operation of the master control unit 11 is determined.

For example, even though the output signal for turning on the switching unit 15 is not outputted from the master control unit 11 but the salt is detected from the heat source 17 or the output signal is outputted from the master control unit 11 If no salt is detected from the heat source 17, it can be determined that the master control unit 11 is abnormal.

When the master control unit 11 normally operates, the slave control unit 13 may not be involved in the control of the heat source 17. [ At this time, the slave control unit 13 can be operated in the standby mode.

In the standby mode, the control operation of the master control unit 11 is performed, but the control operation of the slave control unit 13 is not performed and can be maintained in the standby state.

When the master control unit 11 is abnormally operated, the slave control unit 13 can enter the operation mode. Accordingly, the slave control unit 13 can control the heat source 17 instead of the master control unit 11.

The control operation of the master control unit 11 can be performed by the slave control unit 13 in the operation mode.

For example, the slave controller 13 may control the switching unit 15 to supply gas or electricity to the heat source 17.

The slave control unit 13 can control the master control unit 11 to be initialized when the master control unit 11 is abnormally operated.

For example, when the master control unit 11 is abnormally operated, the slave control unit 13 can output an initialization control signal to the master control unit 11. [ The master control unit 11 can be initialized in response to this initialization control signal.

In addition, the master control unit 11 can provide initialization result information to the slave control unit 13.

When the master control unit 11 is initialized through the initialization result information, the slave control unit 13 can pass the control function of the heat source 17 to the master control unit 11. [

For example, when the master control unit 11 is initialized through the initialization result information, the slave control unit 13 can enter the standby mode. Accordingly, the slave control unit 13 can not only output the output signal for controlling the switching unit 15, but also can provide the control function release signal to the master control unit 11.

In this case, the master control unit 11 may be driven in response to the control function release signal to perform the control function of the heat source 17. Here, the control function of the heat source 17 includes all of the sensing function, the determination function, the control function, and the output function, and may be any function that the master control unit 11 can perform.

Alternatively, when the master control unit 11 is initialized regardless of whether the master control unit 11 receives the control function release signal from the slave control unit 13, the master control unit 11 is automatically driven to control the heat source 17 Function may be performed.

In the standby mode, the control operation of the slave control unit 13 may be canceled, but the control operation of the master control unit 11 may be performed.

The slave control unit 13 informs the master control unit 11 of the failure through the display unit (not shown) so that the failure of the master control unit 11 is corrected The master control unit 11 can be replaced.

2 is a flowchart illustrating a method of controlling a cooking device according to an embodiment of the present invention.

1 and 2, the master control unit 11 and / or the slave control unit 13 may receive a salt detection signal (S111).

The salt detection signal can be detected by the salt detection unit 19. [

The salt detection signal may be provided to the master control unit 11 and the slave control unit 13 simultaneously or selectively.

The master control unit 11 and / or the slave control unit 13 may receive the output detection signal (S113).

An output signal for controlling the switching unit 15 may be output to the output terminal of the master control unit 11 connected to the switching unit 15. [

For example, the output signal may have a low level (00) or a high level (11).

The switching unit 15 is turned off by the low level output signal and the switching unit 15 can be turned on by the high level output signal.

This output signal can be sensed by the output end sensor 21. Fig. That is, the output edge detection unit 21 can output the output depression signal based on the output signal output to the output terminal of the master control unit 11. [

The output sense signal may or may not be the same as the output signal.

The output detection signal may be provided to the master control unit 11 and the slave control unit 13 simultaneously or selectively.

The slave control unit 13 can communicate with the master control unit 11 and receive the status information of the master control unit 11 (S115).

The master control unit 11 may check its state at any time and provide state information on the presence or absence of the abnormality to the slave control unit 13. [

The order of S111, S113, and S115 may be changed. For example, it may be operated in the order of S115, S113, and S111, or may be operated in the order of S113, S115, and S111.

Or S111, S113, and S115 may be operated simultaneously in parallel.

In the present invention, when the master control unit 11 is driven, the slave control unit 13 may not be driven.

In addition, when an error occurs in the master control unit 11, the slave control unit 13 can be driven.

Therefore, even if the salt sensing signal from the salt sensing unit 19 and the output sensing signal from the output sensing unit 21 are supplied to the slave control unit 13, the slave control unit 13 is not driven, The control operation is not performed.

The salt sensing signal and the output sensing signal can be received and the communication function of the master control unit 11 can be activated even if the slave control unit 13 is not driven.

The master control unit 11 may determine whether the heat source 17 is abnormal based on the salt detection signal and the output detection signal and may control the heat source 17 through the switching unit 15 according to the determination result. That is, when there is an abnormality in the heat source 17, the switching unit 15 is controlled to be turned off so that the supply of gas or electricity to the heat source 17 can be interrupted.

On the other hand, the slave controller 13 may determine whether the master control unit 11 is in the abnormal state based on the salt detection signal, the output detection signal, and / or the state information of the master control unit 11 (S117).

If the control state of the master control unit 11 is normal, the master control unit 11 continuously controls the heat source 17 as it is, and the slave control unit 13 performs any operation for controlling the heat source 17 (S119).

The slave control unit 13 can control the heat source 17 instead of the master control unit 11 when the control state of the master control unit 11 is abnormal or the master control unit 11 is inoperable ).

When the control state of the master control unit 11 is abnormal, the state information of the master control unit 11 provided from the master control unit 11 indicates that the salt from the heat source 17 When the output signal is outputted to the output terminal of the master control unit 11 or the output signal is outputted from the output terminal of the master control unit 11 but the salt is not detected from the heat source 17 have.

If the control state of the master control unit 11 is abnormal, the slave control unit 13 can provide an output signal to the switching unit 15 through its output terminal. By switching off the switching unit 15 by this output signal, the supply of gas or electricity supplied from the supply source to the heat source 17 can be cut off.

The slave control unit can initialize the master control unit 11 (S123).

The slave control unit 13 may generate an initialization signal for disabling the operation of the master control unit 11 and provide the initialization signal to the master control unit 11. [

The master control unit 11 can be initialized in response to the initialization signal provided from the slave control unit 13. [

The master control unit 11 can provide the slave control unit 13 with the result information on the initialization.

The slave control unit 13 can confirm whether the initialization of the master control unit 11 is successful based on the initialization result information (S125).

If the initialization of the master control unit 11 is successful, the control operation of the master control unit 11 can be normally performed (S127). In this case, the slave control unit 13 enters the standby mode and does not participate in the control of the heat source 17.

If the initialization of the master control unit 11 is not successful, the state of the master control unit 11 can be informed to the user through the display unit (not shown) (S129).

The state of the master control unit 11 may be an operation disabled state of the master control unit 11. [

For example, the current master control unit 11 is inoperable on the display unit and can not be initialized. Therefore, the message 'the master control unit 11 seems to be replaced' may be displayed.

Although the master controller 11 and the slave controller 13 are referred to as the master controller 11 and the slave controller 13, the master controller 11 may be referred to as a first controller and the slave controller 13 may be referred to as a second controller.

According to the present invention, even if the master control unit 11 fails, the slave control unit 13 can replace the role of the master control unit 11 by monitoring the state of the master control unit 11, thereby improving the product reliability of the cooking device Be able to

According to the present invention, when the master control unit 11 fails, the slave control unit 13 can control the heat source 17 in place of the master control unit 11, so that the ignition or the like caused by the operation failure of the master control unit 11 So that the stability of the cooking device can be secured.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
