The present invention relates to a heating cooker configured to perform heating cooking by selecting and setting a desired cooking menu from a plurality of preset cooking menus.

For example, in the microwave oven which can be automatically cooked, heating cooking is automatically executed by selecting a desired cooking menu from a plurality of cooking menus. In this case, a selection key is provided on the operation panel corresponding to each cooking menu and a desired cooking menu is selected by pressing any of the selection keys.

However, in the above-described configuration, there is an unreasonable effect of increasing the size of the operation panel since the number of cooking menus is accompanied by an increase in the number of cooking menus. On the other hand, there have been methods of selecting a desired cooking menu while reducing the number of operation keys and sequentially shifting the cooking menu displayed by the repeated pressing operation, which also makes the selection operation of the cooking menu cumbersome and inconvenient to use. There was irrationality.

Therefore, in recent years, miniaturization has been made by reducing the number of operation keys and improving the method of use thereof.

That is, for example, a plurality of cooking menus are displayed in advance by dividing them into a plurality of pairs of cooking menu groups, and when one operation dial is rotated in one direction, the cooking menu group can be selected and the displayed operation is rotated in another direction. The cooking menu in the menu group can be selected, and pressing and operating this operation dial allows the heating of the selected cooking menu to be started.

According to this method, the user can select a desired cooking menu with a simple operation by simply rotating the operation dial without any complicated operation of pressing the operation key several times, and pressing the operation dial. It is excellent to use because heating cooking can be started just by operating.

However, in the above cases, heating must be started after the selection operation of the cooking menu is finished, for example, by rotating the operation dial, so that when the operation dial is pressed, the rotation may be made by mistake. In this case, since the cooking menu is selected and set according to the rotation operation, the cooking menu to be set is different from the one desired. In this state, if the operation dial is pressed without the user's realization, the heating cooking is executed in the wrong setting state. There is.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the object thereof is that the set operation dial is not changed and set even when the displacement operation is made by mistake during the pressing operation of the operating member, and the heating is performed while the desired cooking menu is surely set. It is to provide a heating cooker capable of performing cooking.

The heating cooker according to the present invention made as described above has a display means for displaying a plurality of cooking menus, and one cooking menu is selectably installed from the plurality of cooking menus according to the displacement operation in a predetermined direction. The operating member and the cooking menu selected by the displacement operation of the operating member are set, and when there is an input by a pressing operation after a stop period of the displacement operation of the operating member continues for a predetermined time, it is accepted and entered into the set cooking menu. And a control means for executing heating cooking according to the present invention, wherein the control means is configured to perform the cooking menu selection operation when the displacement operation of the operation member is greater than or equal to a predetermined amount in a state of accepting the pressing operation by the operation member. It features.

According to the heating cooker of the present invention having the above-described configuration, one cooking menu can be selected from a plurality of cooking menus as the operation member is displaced in a predetermined direction, and the selected cooking menu is set to be heated by the control means. do. The control means receives this only when the operation member is displaced by a predetermined amount or more when the operation member is in a state of accepting the input of the opening by pressing the operation member after the operation that the operation member is not displaced for a predetermined time continues. Since the selection operation of the cooking menu is indented, even if the operation member is accidentally displaced during the pressing operation, if the amount of displacement is less than or equal to the predetermined amount, the set cooking menu is not changed.

On the contrary, in the case where the cooking menu is changed and set in the above state, if the operation member is displaced by a predetermined amount or more, the selection operation can be performed again. Therefore, since the selection operation and the operation at the start of the operation by the displacement operation and the pressing operation of the operation member are easy, the method of use is improved.

Hereinafter, an embodiment in which the present invention is applied to a microwave oven having an automatic cooking function will be described with reference to the drawings.

2 shows the appearance of the entire configuration. In the outer box 1 of the microwave oven, a heating cooking chamber 2 and a machine room (not shown) are installed to the left and right. Oscillation operation (see FIG. 1) to heat cook the heated object in the heating cooking chamber 2. In oven cooking or grill cooking, the heated object in the heating cooking chamber 2 is heated and heated by energizing the oven heater 4 and the grill heater 5 to generate heat.

On the other hand, a door 6 for opening and closing the heating cooking chamber 2 is provided on the front surface of the outer box 1, and an operation panel 7 is provided on the front surface of the machine room. As shown in FIG. 3, the operation panel 7 is provided with a display unit 8 for displaying time, cooking setting state, etc., and a menu display unit 9 for displaying a plurality of cooking menus as display means.

The menu display unit 9 is divided into a plurality of pairs of cooking menu groups 9a, 9b, and 9c, and a plurality of cooking menus are displayed on each of them. As described later, when the display output is given, the selected one of the cooking menu groups 9a to 9c is lit and displayed, and the corresponding cooking menu thereof is lit and displayed.

The operation dial 10 serving as an operation member provided below the menu display unit 9 is configured to be displaced in the clockwise and counterclockwise directions in the predetermined direction and at the same time capable of pressing. The operation dial 10 outputs a signal corresponding to the rotation operation direction and the rotation angle to the control circuit 11 (see FIG. 1), whereby a plurality of displays displayed in the cooking menu groups 9a, 9b, 9c. It is possible to select one desired cooking menu from the cooking menu. On the other hand, when the operation dial 10 is pressed, a signal for starting heating cooking is input to the control circuit 11.

In the lower part of the operation dial 10, an operation key 12 for selecting a cooking menu by manual operation is provided. This operation key 12 consists of key switches 12a, 12b, 12c, etc., for example, and it can also select a desired cooking menu by this.

The control circuit 11 has a function as a control means. The control circuit 11 includes a microcomputer, a memory, and the like, and a program for performing heating cooking is stored in advance. As shown in FIG. 1, the magnetron 3 is connected to the control circuit 11 via the driving circuit 3a, and the oven heater 4 and the grill heater 5 are the driving circuits 4a and 5a, respectively. Is connected via The control circuit 11 is also connected with a sensor unit 13 provided with various sensors for detecting a cooking state.

Then, the control circuit 11 drives the drive signal through the drive circuits 3a, 4a, and 5a to the magnetron 3, the oven heater 4, and the grill heater 5, corresponding to the set heating cooking conditions. Heating is performed by giving.

Next, the operation of this embodiment will be described with reference to FIGS. 4 to 6.

First, the case of selecting a cooking menu of automatic cooking will be briefly described. That is, when the operation dial 10 is rotated in the right direction, for example, the number of pulses corresponding to the rotation angle which is changed by the rotation is input to the control circuit 11.

The control circuit 11 detects the rotational direction and the rotational displacement amount due to a signal from the operation dial 10 by executing a program (not shown). Display signals are sequentially given to 9a) to (9c). Accordingly, the cooking menu groups 9a to 9c given the display signal are in display state in turn, and the cooking menu groups 9a, 9b and 9c according to the rotational operation in the right direction of the operation dial 10 by the user are displayed. ) Is selected.

Next, when the operation dial 10 is rotated in the left direction, as described above, the control circuit 11 detects the angle rotated in the left direction and selects the selected display from the cooking menu groups 9a to 9c according to the value. We display cooking menu sequentially from state.

In this way, the user selects and sets one of the cooking menu groups 9a to 9c according to the rotation operation of the right direction of the operation dial 10 and rotates to the left direction. Since one of a plurality of cooking menus in (9c) can be selected, as a result, one desired cooking menu can be selected and set from a plurality of cooking menus by a simple operation.

When the cooking menu is selected and set as described above, the control circuit 11 reads out and sets the heating conditions of the cooking menu corresponding to the set state from the memory. When the state in which the operation of selecting the cooking menu by the rotation operation of the operation dial 10 is not performed elapses for a predetermined time T, the input at the start of the operation by the pressing operation of the operation dial 10 becomes acceptable. .

Therefore, after the operation dial 10 is pressed, the control circuit 11 accepts an input at the start of cooking and performs heating cooking corresponding to the set cooking menu.

On the other hand, when the user performs the rotation operation of the operation dial 10 for selecting the cooking menu again before a predetermined time T elapses, the control circuit 11 according to the rotation operation of the operation dial 10 The above-described selection operation of the cooking menu is performed again.

Then, for example, when the user selects and sets a desired cooking menu, and when the operation dial 10 is pressed in a state where a predetermined time T has elapsed, or when the operation is accidentally rotated, or the selected set cooking, An operation in the case of changing the menu will be described with reference to the flowchart of the program shown in FIG.

That is, FIG. 4 shows a part of the program step executed when the control circuit 11 executes a program including the operation of selecting the cooking menu as described above. The control circuit 11 first determines whether the acceptance state at the start of the stop is performed in step S1, and is not in an acceptable state when the cooking menu selection operation is still performed by the rotation operation of the operation dial 10. No ", and the flow proceeds to step S2.

Next, when the operation dial 10 is rotated, the control circuit 11 determines "YES" in step S2, shifts to step S3, performs a selection operation of the cooking menu, and ROMs the heating cooking conditions of the selected cooking menu. Read from and set. Thereafter, the control circuit 11 starts the timer function in step S4 and starts counting the time t until the operation dial 10 is rotated.

Thereafter, the control circuit 11 executes a program (not shown), and when it reaches step S1 again, when the count time t by the timer function has not yet reached a predetermined time T, it is determined as "No". If there is no rotation operation of the operation dial 10, it is determined as "No", and the flow proceeds to Step S5. If the count time t does not reach a fixed time T here, it is determined as "No". Move to a program not shown.

When the control circuit 11 determines "YES" in step S5 while repeating the above program, that is, when the count time t becomes longer than the predetermined time T, the control circuit 11 proceeds to step S6 to accept the start of the stop. It becomes a starting state. That is, in this state, when there is an input at the start of the operation by pressing the operation dial 10 as described above, the control circuit 11 is in a state of accepting this.

Accordingly, when the control circuit 11 reaches step S1 again, the control circuit 11 judges "YES" and proceeds to step S7 to determine whether or not the push operation input of the operation dial 10 has been made. At this time, when the operation dial 10 is pressed, the control circuit 11 proceeds to step S8 to perform heating cooking under heating cooking conditions corresponding to the set cooking menu. In addition, the state of the signal output corresponding to the rotation operation of this operation dial 10 is shown in FIG.

Then, when the control circuit 11 judges "YES" in step S1 and does not press the operation dial 10 when it moves to step S7, it determines with "No" here, and moves to step S9. In step S9, the control circuit 11 judges "No" when the operation dial 10 is not rotated, and moves to a step not shown in the figure. When the control operation is performed, the control circuit 11 determines "YES" and moves to step S10.

By the way, in step S10, the control circuit 11 determines whether the operation dial 10 has been rotated more than a predetermined angle. For example, at this time, when the operation dial 10 is rotated by a predetermined angle or more, the control circuit 11 determines that the rotation operation is performed to change the cooking menu selected by the user, that is, it is determined as "YES", and the flow proceeds to step S11. In step S11, the acceptance of the input at the start of the diaphragm by the pressing operation of the operation dial 10 is made into a prohibited state. 6 shows the state of the signal output according to the rotation operation of the operation dial 10 as described above.

On the other hand, when the user rotates the operation dial 10 to select a desired cooking menu and then starts heating cooking, for example, when the operation is slightly rotated by mistake, the rotation operation amount is usually set to a predetermined angle. Since it does not arrive, the control circuit 11 determines "No" and moves to the step not shown as it is.

Therefore, when the user presses the operation dial 10 afterwards, the control circuit 11 judges that it is "YES" and starts heating cooking when it reaches step S7 again through step S1 (step S8).

According to the present embodiment as described above, after a predetermined time T has elapsed after the cooking menu is selected by the rotating operation of the operation dial 10, the control circuit 11 is input to the control circuit 11 in a state in which the input at the start of the opening is enabled. Since the operation dial 10 accepts the change and selection operation of the cooking menu only when the operation dial 10 is rotated by a predetermined angle or more, the operation dial is input to input the start of the cooking after a predetermined time (T) has elapsed after the selection operation of the cooking menu has ended. Even when the operation dial 10 is rotated a little by mistake when pressing (10), the set cooking menu is not changed and the user's efficiency is improved.

In the above embodiment, the operation dial 10 for selecting the cooking menu is provided by the rotational operation. However, the configuration is not limited thereto, and for example, an operation member that is displaced in a linear direction may be used. have.

In the above embodiment, a plurality of cooking menus are selected by dividing them into cooking menu groups 9a, 9b, and 9c, but not limited thereto. You may.

In the above embodiment, a plurality of cooking menus are selected by dividing them into cooking menu groups 9a, 9b, and 9c, but not limited thereto. For example, the rotation operation of the operation dial 10 without dividing the groups. The plurality of cooking menus may be displayed in order according to rotation in order to select.

As described above, according to the heating cooker of the present invention, since the control means accepts the pressing operation by the operation member, the cooking menu selection operation is performed only when the displacement operation of the operation member is performed by a predetermined amount or more. When the desired cooking menu is selected and set by the displacement operation of the operating member, and heating cooking is performed by pressing operation after a certain time has elapsed, for example, even if only a small amount of displacement operation is made by mistake, the amount of displacement exceeds a predetermined amount. If it is not reached, the operation of selecting a cooking menu is not performed, so that the user can execute heating cooking without the trouble of resetting, and has an excellent effect of improving the method of use.
