Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker capable of performing cooking by selectively setting a desired cooking menu from a plurality of preset cooking menus.

[0002]

2. Description of the Related Art For example, some microwave ovens capable of automatically cooking automatically select a desired cooking menu from a plurality of cooking menus to automatically perform heating and cooking. In this device, a selection key is provided on the operation panel corresponding to each cooking menu, and a desired cooking menu is selected by pressing any one of the selection keys.

However, in the above-mentioned configuration, the number of selection keys increases excessively as the number of cooking menus increases, which causes a problem that the operation panel becomes large. On the other hand, in the method of reducing the number of operation keys and selecting the desired cooking menu while sequentially moving the cooking menu by repeating the pressing operation, the selection operation of the cooking menu becomes troublesome and the usability becomes poor. There was a problem.

Therefore, recently, there has been considered a device in which the number of operation keys is reduced and the usability thereof is improved to reduce the size thereof.

That is, for example, a large number of cooking menus are divided into a plurality of cooking menu groups and displayed in advance.
With the individual operation dial, you can select the cooking menu group by rotating it in one direction, and you can select the cooking menu in the displayed cooking menu group by rotating it in the other direction. Further, when the operation dial is pressed, heating cooking of the selected cooking menu can be executed.

As a result, the user can select a desired cooking menu without performing a troublesome operation such as repeatedly pressing the operation key.
Further, since heating and cooking can be started only by pressing the operation dial, it is excellent in usability.

[0007]

However, in the above-mentioned one, for example, if the pressing operation is accidentally performed while the selection operation of the cooking menu is being performed by the rotation operation of the operation dial, the desired operation is still desired. The heating cooking will be started in a state where the cooking menu cannot be selected, and there is a possibility that cooking different from the cooking intended by the user will be performed.

Even if the user notices it, when he / she wants to change and set a desired cooking menu, it is necessary to perform the setting operation after performing the reset operation once, and then the cooking start operation. There is a problem that the operation becomes troublesome and the usability becomes poor.

The present invention has been made in view of the above circumstances, and an object thereof is to easily change a setting to a desired cooking menu even if a pressing operation is accidentally performed during a displacement operation of an operation member. It is to provide a heating cooker capable of performing appropriate heating cooking.

[0010]

The cooking device of the present invention comprises:
Display means for displaying a plurality of cooking menus, an operating member which is provided so that one cooking menu can be selected from the plurality of cooking menus by displacement operation in a predetermined direction, and which can be pressed, and an operating member of the operating member. And a control means for setting the cooking menu selected by the displacement operation and performing heating and cooking according to the cooking menu set when the operating member is pressed for a certain time or more, and the control means, When the displacement operation is performed before the elapse of a certain time while the operation member is being pressed, the selection operation of the cooking menu is performed and a predetermined response time has elapsed from the time when the menu selection operation is completed. It is characterized in that it is configured to start the above-mentioned cooking sometimes.

[0011]

According to the heating cooker of the present invention, one cooking menu can be selected from a plurality of cooking menus by displacing the operating member in a predetermined direction, and the selected cooking menu is It is set to be cooked by the control means. Then, the control means executes the heating cooking corresponding to the set cooking menu when the operation member is pressed for a certain time or more.

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

Therefore, even if the user erroneously performs the pressing operation during the displacement operation of the operating member, cooking is started every time the operating member is displaced again until a certain period of time elapses in that state. Since the response time up to is extended, it is possible to execute the heating cooking after the desired cooking menu is selected and set easily without urgent operation.

FIG. 2 shows the external appearance of the entire structure. A heating and cooking room 2 and a machine room (not shown) are arranged on the left and right inside an outer box 1 of the microwave oven. The provided magnetron 3 (see FIG. 1) is oscillated to heat and heat the object to be heated in the cooking chamber 2. Further, during oven cooking or grill cooking, an object to be heated in the cooking chamber 2 is cooked by energizing the oven heater 4 and the grill heater 5 to generate heat.

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

The menu display section 9 is divided into a plurality of sets of cooking menu groups 9a, 9b, 9c, and a plurality of cooking menus are displayed in each of them. As will be described later, these are adapted to, when a display output is given, illuminate and display a selected one of the cooking menu groups 9a to 9c and illuminate and display the corresponding cooking menu among them. ..

The operation dial 10, which is an operation member disposed below the menu display portion 9, can be displaced in predetermined clockwise and counterclockwise directions and can be pressed. ing. 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), and thereby the plurality of cooking menus displayed in the cooking menu groups 9a, 9b, 9c are displayed. One of the cooking menus you want can be selected. On the other hand, this operation dial 10
When is pressed, a signal for starting heating and cooking is input to the control circuit 11.

Below the operation dial 10, an operation key 12 for manually selecting a cooking menu is provided. The operation key 12 is composed of, for example, key switches 12a, 12b, 12c and the like, which also enables selection of a desired cooking menu.

The above-mentioned control circuit 11 has a function as a control means and is constituted by including a microcomputer, a memory and the like, and a program for heating and cooking is stored and set in advance. As shown in FIG. 1, in the control circuit 11, the magnetron 3 described above is connected to the drive circuit 3.
The oven heater 4 and the grill heater 5 are connected via drive circuits 4a and 5a, respectively. Further, the control circuit 11 is connected to a sensor unit 13 provided with various sensors for detecting a cooking state.

Then, the control circuit 11 heats the magnetron 3, the oven heater 4 and the grill heater 5 by supplying drive signals via the drive circuits 3a, 4a and 5a in accordance with the set cooking conditions. It is designed to carry out cooking.

Next, the operation of this embodiment will be described with reference to FIGS. It should be noted that in the present embodiment, the description will be made focusing on the case where a change is made in the case where cooking is started by mistakenly pressing when rotating the operation dial 10.

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

The control circuit 11 detects the rotational direction and the rotational displacement amount based on the signal from the operation dial 10 by executing a program (not shown). In this case, the angle rotated to the right is detected. Depending on the cooking menu group 9
Display signals are sequentially applied to a to 9c. Accordingly, the cooking menu groups 9a to 9 to which the display signal is given
c is sequentially displayed, and the user selects the cooking menu group in accordance with the operation of rotating the operation dial 10 to the right.

Next, when the operation dial 10 is rotated to the left, the control circuit 11 similarly detects the angle rotated to the right and selects the cooking menu group 9a to 9c according to the detected angle. The cooking menus are sequentially displayed from the displayed ones.

As described above, the user operates the operation dial 10
By rotating the rightward of the cooking menu group 9a
To 9c, one of them is selected and set, and the cooking menu group 9a of the selected cooking menu
9c can select one of a plurality of cooking menus, and as a result, a desired one 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 in this way, the control circuit 11 reads the heating condition of the cooking menu according to the setting state from the memory and sets it. After that, when the operation dial 10 is pressed,
The control circuit 11 starts the cooking start timer, and when the time during which the pressing operation is performed has passed the predetermined time T, the control circuit 11 accepts this and executes the heating and cooking.

However, even if the user accidentally presses the operation dial 10 while the user is selecting and setting a desired cooking menu, the control circuit 11 makes the selection as follows. It accepts setting operations.

That is, FIG. 4 shows a part of the steps performed when the control circuit 11 is executing the above-mentioned program, and the control circuit 11 determines whether or not the operation dial 10 has been pressed. Is determined in step S1.

When the operation dial 10 is being pressed, the control circuit 11 determines "YES" and proceeds to step S2 to start the time counting operation by the cooking start timer, and then proceeds to step S3. Further, when the control circuit 11 determines “NO” in step S1,
At step S4, the time counting operation by the cooking start timer is stopped, the count value is cleared, and then step S3 is started.

In step S3, the control circuit 11 determines whether or not the operation dial 10 is being rotated. If it is, the control circuit 11 determines "YES" and proceeds to step S5. After clearing the count value of the cooking start timer and starting counting from zero again, step S
Proceed to 6. In addition, the control circuit 11 determines "N" in step S3.
When it is determined to be "O", the process proceeds to step S6 without passing through step S5.

The control circuit 11 judges in step S6 whether or not the count value by the cooking start timer has reached the predetermined time T. If not, it judges "NO" and proceeds to the subsequent program step. If "YES" is determined at this point, the process proceeds to step S7, the heating and cooking start process is performed, and the process proceeds to the subsequent program step.

In this case, immediately after the operation dial 10 is pressed, after the steps S1, S2 and S3, the count value of the cooking start timer has not reached the predetermined time T in step S6. Move to the next program step without executing.

Then, when the operation dial 10 is in the depressed state, the count value of the cooking start timer is added while the program shown in FIG. 4 is repeatedly executed. When the pressing operation of the operation dial 10 is released and turned off before reaching T (see FIG. 5 (a)), the control circuit 11 causes the control circuit 11 to perform the step S4.
Since the cooking start timer is stopped and the count value is cleared, the cooking start process is not executed.

When the state where the operation dial 10 is pressed is continued and the count value of the cooking start timer reaches a certain time T (see FIG. 5A), the control circuit 11
Determines "YES" in step S6 and determines in step S7
Will start the process of starting cooking.

That is, the operation dial 1 for starting cooking
In the case of pressing 0, when the ON time is not continued for the fixed time T, the cooking start process is not executed because the user does not have the intention to start the cooking.

Now, the operation dial 10 is operated as described above.
While pressing the button, the operation dial 10
When, for example, the user presses the operation dial 10, but the user presses the operation dial 10 by mistake during the selection operation of the cooking menu, the desired cooking menu is not yet selected. When the rotating operation is performed while the operation dial 10 is being pressed, the control circuit 11 operates as follows.

That is, the control circuit 11 judges "YES" in the step S3 and shifts to the step S5.
The count value of the cooking start timer is cleared and the count operation starts again from zero. As a result, the control circuit 11 determines “NO” in step S6, jumps to step S7, moves to the subsequent program step, and executes the selection operation of the cooking menu by rotating the operation dial 10. Become.

While the cooking menu selection operation is being performed by the turning operation of the operation dial 10, the control circuit 11 immediately starts the time counting operation by the cooking start timer in step S2 in step S5. In order to clear the count value, it is determined to be "NO" in step S6, and the cooking menu selection operation is executed.

When the cooking menu selection operation by rotating the operation dial 10 is completed, the control circuit 11 determines "NO" in step S3 and jumps to step S5, so that the count value of the cooking start timer is cleared. Therefore, when the fixed time T as the response time has elapsed after that, the control circuit 11 returns “YES” in step S6.
Then, the process proceeds to step S7, and the cooking start process is executed (see FIG. 6).

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

According to the present embodiment as described above, even when a cooking start signal is erroneously pressed and a cooking start signal is output when the cooking menu selection is set by rotating the operation dial 10, the control circuit 11 causes It can be changed and set by performing a rotating operation before the elapse of a certain time T. At this time, the cooking start timer is cleared every time the rotating operation is performed, and the time until the start of cooking is extended. The desired cooking menu can be selected and the cooking can be performed by a simple operation without touching even in the pressing operation state, and the usability for the user is improved.

In the above embodiment, the control circuit 11 inputs the start of cooking by pressing the operation dial 10.
By the program, the heating and cooking are executed by determining that a certain time T has passed, but the present invention is not limited to this. For example, the control circuit may be provided after a certain time T has been input to start cooking on the operation dial 10 side. It is also possible to provide a delay circuit or the like for inputting to 11 and to cause the control circuit 11 to perform heating and cooking by the input thereof.

In the above embodiment, a plurality of cooking menus are divided into cooking menu groups 9a, 9b, 9c for selection, but the present invention is not limited to this and, for example, the cooking dial groups of the operation dial 10 are not divided. A method may be used in which a plurality of cooking menus are sequentially displayed and selected by a rotating operation.

Further, in the above embodiment, the response time is set to the same time as the fixed time T, but the time is not limited to this and may be set to a different time.

Further, instead of the operation dial 10, an operation member which is operated to be displaced in a linear direction may be used.

[0047]

As described above, according to the heating cooker of the present invention, when the operating member is pressed,
When the displacement operation is performed before the elapse of a certain time, the cooking menu selection operation is performed, and the heating cooking is started when a predetermined response time elapses from the time when the menu selection operation ends. Therefore, even if the user accidentally presses during the displacement operation of the operating member, until the certain time elapses in that state, the operation member is again displaced until the cooking starts. The response time is extended, and it is possible to select and set a desired cooking menu and execute heating cooking with a simple operation without touching the pressing operation state. Therefore, it is convenient for the user. It has an excellent effect of improving.
