The present invention relates to a heating cooker for heating cooking by selecting and setting a desired cooking menu among a plurality of cooking menus already set.

In a microwave oven capable of automatic cooking, 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 and operating something of the selection key.

However, the above-described configuration is inconvenient to increase the size of the operation panel because the number of the selection keys increases excessively with the increase of the number of cooking menus. On the other hand, the method of selecting a desired cooking menu while reducing the number of operation keys and sequentially shifting the cooking menu by the repetition of the operation has the inconvenience of making the selection of the cooking menu cumbersome and worsening the usage.

Therefore, in recent years, it has been devised to reduce the number of operation keys, improve their usage, and reduce their size.

For example, several cooking menus are displayed in advance in a plurality of sets of cooking menu groups and rotated in one direction by one operation dial to select an operation menu. The cooking menu from the displayed cooking menu group can be selected. When the operation dial is operated again, heating cooking of the selected cooking menu is executed. As a result, the user can select a desired cooking menu without performing the complicated operation that causes the operation of pressing the operation key many times, and the heating cooking can be started only by pressing the operation dial.

However, in the above-described manner, for example, if the cooking operation is incorrectly pressed when the cooking menu is selected by the rotation operation of the control dial, heating cooking is started in a state in which the desired cooking menu cannot be selected yet. There is a fear that cooking different from the intended cooking may be performed.

In addition, even if the user finds it, when changing the setting to the desired cooking menu, the setting operation is performed after the reset operation once. Therefore, it is necessary to perform the operation at the start of the aperture again, which makes the operation cumbersome and easy to use. There is discomfort that worsens.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a heating cooker capable of executing appropriate heating cooking by simply changing the setting to a desired cooking menu even when a pressing operation is performed during the displacement operation of the operating member.

The heating cooker according to the present invention includes display means for displaying a plurality of cooking menus, an operation member operable to press and simultaneously operate one cooking menu from among the plurality of cooking menus by displacing in a predetermined direction; A control means for setting a cooking menu selected by the displacement operation of the operating member and pressing the control member for a predetermined time and performing heating cooking according to the set cooking menu, and pressing the control means. In the operated state, when the displacement operation is performed before a predetermined time has elapsed, the cooking operation is selected, and the heating cooking is started when a predetermined response time has elapsed when the menu selection operation is completed. Characterized by the point.

According to the heating cooker of the present invention, 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 only by heating cooking by the control means. The control means executes heating cooking corresponding to the set cooking menu when the operation member is pressed for a predetermined time or longer.

At this time, the control means changes and sets the set cooking menu according to the selection operation if the displacement operation is performed while the operation member is pushed and operated until a predetermined time elapses. When the response time elapses, the heating cooking corresponding to the changed and set cooking menu is started.

Therefore, even if the user presses the wrong operation during the operation of displacing the operating member, the response time until the start of the operation is extended when the operating member is displaced again until a certain time elapses in that state, so the operation is embarrassed. It is possible to execute heating cooking simply by selecting and setting the desired cooking menu.

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

FIG. 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, and the microwave oven (3) is installed in this machine room during the heating of the microwave oven. Oscillation operation (see FIG. 1), and heating the heated object in the heating cooking chamber (2). At the time of oven cooking or grill cooking, the heated object in the heating cooking chamber 2 is heated and cooked by energizing the oven heater 4 and the grill heater 5.

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

The menu display unit 9 is divided into a plurality of sets of cooking menu groups 9a, 9b, and 9c, and a plurality of cooking menus are displayed on each of them. When a display output is provided as described later, these display the selected one of the cooking menu groups 9a to 9c on and display the cooking menu corresponding thereto.

At the bottom 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 above-described control circuit 11 has a function as a control means, and includes a microcomputer, a memory, and the like, and a program for heating and cooking is stored in advance. As shown in FIG. 1, the above-described magnetron 3 is connected to the control circuit 11 through the drive circuit 3a, and the oven heater 4 and the grill heater 5 are respectively driven circuit 4a. It is connected via (5a).

The control circuit 11 is also connected with a sensor unit 13 provided with various sensors for detecting a cooking state.

The control circuit 11 supplies driving signals to the magnetron 3, the oven heater 4, and the grill heater 5 through the respective driving circuits 3a, 4a and 5a in response 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. In the present embodiment, a description will be given mainly on the case of changing the case where the start of the stop is performed by a wrong pressing operation during the rotation operation by the operation dial 10.

First, the case of selecting a cooking menu of automatic cooking will be briefly described. That is, when the operation dial 10 is rotated to the right direction, for example, the signal according to the resistance value changed by the rotation is input into the control circuit 11.

As the control circuit 11 executes a program (not shown), the control circuit 11 detects the rotation direction and the rotation displacement amount based on the signal from the operation dial 10, and in this case, the cooking menu group ( Display signals are sequentially given to 9a) to (9c). Accordingly, the cooking menu groups 9a to 9c to which the display signal is applied are sequentially displayed, and the cooking menu group is selected as the user rotates the operation dial 10 in the right direction.

Next, when the operation dial 10 is rotated in the left direction, the control circuit 11 similarly detects the angle rotated in the right direction, and according to the value, the control circuit 11 returns to the selected display state in the cooking menu groups 9a to 9c. The cooking menu is displayed sequentially.

In this way, the user selects and sets one of the cooking menu groups 9a to 9c according to the rotation operation of the operation dial 20 in the right foot direction, and rotates to the left, thereby selecting the selected cooking menu group 9a. Since one of the plurality of cooking menus can be selected from (9c), as a result, one desired cooking menu can be selected and set from the plurality of cooking menus by simple operation.

When the cooking menu is selected and set as described above, the control circuit 11 reads and sets the heating conditions of the cooking menu according to the setting state from the memory. Then, when the operation dial 10 is pressed and operated, the control circuit 11 starts the aperture start timer 11a, and when the pressing operation time has elapsed for a predetermined time T, the control circuit 11 accepts this and executes heating cooking.

The control circuit 11 accepts the selection setting operation as follows even when the user presses the wrong operation dial 10 while the user selects and sets the desired cooking menu.

4 shows a part of the steps performed when the control circuit 11 executes the program as described above, and the control circuit 11 determines in step S1 whether the operation dial 10 has been pressed or not. It is supposed to be done.

When the operation dial 10 is pressed, the control circuit 11 judges "YES" and moves to step S2, starts the time measurement operation by the aperture start timer 11a, and then proceeds to step S3. . When the control circuit 11 judges "NO" in step S1, the control circuit 11 shifts to step S4, stops the time measurement operation by the aperture start timer 11A, and simultaneously clears the counter value. It is supposed to move to.

The control circuit 11 judges whether or not the operation dial 10 is rotated at step S3, and if it is rotated, judges " YES " and proceeds to step S5, and the counter value of the aperture start timer 11a. After clearing to start counting again at zero, the process proceeds to step S6. When the control circuit 11 determines "NO" in step S3, the control circuit 11 proceeds to step S6 without passing through step S5.

In step S6, the control circuit 11 determines whether or not the count value by the aperture start timer 11a has reached a predetermined time T. If not, the control circuit 11 judges "NO" and proceeds to the next program step. If "YES" is determined at this point in time, the flow advances to step S7 to start heating cooking and proceed to the subsequent program step.

In this case, immediately after the operation dial 10 is pressed down, after passing through steps S1, S2 and S3, step S7 is executed because the count value of the aperture start timer 11a has not yet reached a predetermined time T in step S6. The process then proceeds to the next program step.

When the operation dial 10 is in the pressed operation state, the count value of the diaphragm start timer 11a is added while the program shown in FIG. 4 is repeatedly executed, but the count value is a fixed time T. If the pressing operation of the operation dial 10 is cleared and turned off before reaching (see also FIG. 5A), the control circuit 11 stops the aperture start timer 11a and clears the count value at step S4. The processing at the start of aperture stops.

When the operation state of the operation dial 10 is pushed continues and the aperture timer 11a count value reaches a predetermined time T (see also FIG. 5B), the control circuit 11 determines "YES" in step S6. In step S7, the aperture start processing is executed.

In other words, when the operation dial 10 is pressed for the start of the aperture, when the time does not continue for a predetermined time T, the user does not want to start the aperture so that the process of starting the aperture is not executed.

As described above, when the operation dial 10 is pressed and continues, when the operation dial 10 is rotated, that is, the user presses the operation dial 10, for example, the cooking menu is selected. Since the desired cooking menu is not yet selected because the wrong operation was performed during the operation, the control circuit 11 operates as follows when the rotation operation is performed while the operation dial 10 is pressed.

That is, the control circuit 11 judges "YES" at step S3, and moves to step S5, where the count value of the aperture start timer 11a is cleared, and the count value is started again at zero. As a result, the control circuit 11 judges "NO" in step S6, jumps to step S7, shifts to the program step of connection, and executes the operation of selecting the cooking menu by the rotation operation of the operation dial 10.

And while the operation of selecting the cooking menu by the rotation operation of the operation dial 10 is performed, the control circuit 11 counts in step S5 soon after starting the time measurement operation by the start timer 11a in step S2. Since the value is cleared, in step S6, it is determined as "NO" and the cooking menu selection operation is executed.

When the operation of selecting the cooking menu by the rotation operation of the operation dial 10 is completed, the control circuit 11 judges "NO" in step S3 and jumps to step S5, so that the count value of the aperture start timer 11a is changed. Therefore, when the predetermined time T as the response time has elapsed, the control circuit 11 determines "YES" in step S6 and proceeds to step S7 to execute the process at the start of aperture. See also 6).

Therefore, the control circuit 11 then executes the heating cooking corresponding to the desired cooking menu changed and set in the subsequent program step.

According to this embodiment as described above, the control circuit 11 outputs the signal at the start of a certain time even when an incorrect pressing operation is performed during the setting operation of the selection of the cooking menu by the rotation operation of the operation dial 10. If the rotation operation is performed between the elapsed branches of T, the setting can be changed. At this time, since the aperture start timer 11a is cleared during the rotation operation and the time until the aperture is extended, there is no panic even in the push operation state. In addition, the user can select a desired cooking menu with a simple operation, and can perform heating cooking, thereby improving usage for the user.

In the above embodiment, heating cooking is performed by determining that the input of the stop when the operation of the operation dial 10 is pressed by the control circuit 11 for a predetermined time T is programmed, but the present invention is not limited thereto. For example, a delay circuit for inputting to the control circuit 11 after a predetermined time T has elapsed is provided on the operation dial 10 side, and the control circuit 11 is heated by the input. It is good also as a structure which performs cooking.

In the above embodiment, a plurality of cooking menus are selected by dividing them into cooking menu groups 9a, 9b, and 9c, but the present invention is not limited thereto. For example, the operation dial 10 is not divided into groups. It is also possible to select and display a plurality of cooking menus sequentially by the rotation operation.

In the above embodiment, the response time is set at the same time as the constant time T, but is not limited thereto.

And instead of the operation dial 10, it can also be set as the structure using the operation member displaced in the linear direction.

As described above, according to the heating cooker of the present invention, when the displacement operation is performed before a predetermined time has elapsed in the state in which the operation member is pressed, the operation of selecting the operation menu is performed and at the time when the menu selection operation is finished, The heating cooking is started when the response time has elapsed. Even when the user presses the wrong member during the displacement operation of the operation member, the operation member is displaced again until a certain time elapses. When the response time until the iris is delayed, it is possible to execute heating cooking by selecting and setting the desired cooking menu by simple operation without being embarrassed even in the pressing operation state. It has a poor effect.
