DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker in which a desired cooking menu is selected and set from a plurality of preset cooking menus to perform heating cooking.

[0002]

2. Description of the Related Art For example, in a microwave oven capable of automatic cooking, there is a microwave oven in which a desired cooking menu is selected from a plurality of cooking menus and heating cooking is automatically executed. In this apparatus, a selection key is provided on the operation panel corresponding to each cooking menu, and a desired cooking menu is selected by pressing one of the selection keys.

[0003] However, in the above-described configuration, the number of the selection keys is excessively increased with the increase in the number of cooking menus, so that there is a problem that the operation panel becomes large. On the other hand, in a system in which a desired cooking menu is selected while sequentially shifting the displayed cooking menu by repeating the pressing operation by reducing the number of operation keys, the selection operation of the cooking menu becomes cumbersome, and the usability is increased. There was a problem that became worse.

[0004] Therefore, recently, there has been considered an apparatus which is reduced in size by reducing the number of operation keys and improving the usability 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 operation dials, it is possible to select a cooking menu group by rotating in one direction, and to select a cooking menu in the displayed cooking menu group by rotating in another direction, Further, when the operation dial is pressed, heating cooking of the selected cooking menu can be executed.

Thus, the user can select a desired cooking menu by a simple operation of simply turning the operation dial without performing a troublesome operation of repeatedly pressing the operation key. In addition, heating and cooking can be started only by pressing the operation dial, so that the operability is excellent.

[0007]

However, in the above-described apparatus, for example, after the selection operation of the cooking menu is completed by rotating the operation dial, the operation dial is pressed to start heating cooking. In some cases, it may accidentally rotate slightly, in which case,
When the selection operation of the cooking menu is performed in response to the rotation operation, the cooking menu to be set is different from a desired cooking menu, and in this state, the operation dial is pressed without the user noticing. Then, there is a problem that the heating cooking is executed in an incorrect setting state.

The present invention has been made in view of the above circumstances, and has as its object that a set cooking menu can be changed and set even if a displacement operation is mistakenly performed at the time of pressing operation of an operation member. Another object of the present invention is to provide a heating cooker that can surely execute heating cooking in a desired cooking menu setting state.

[0009]

Means for Solving the Problems A cooking device according to the present invention comprises:
A display means for displaying a plurality of cooking menus; an operating member which is provided so as to be able to select one of the cooking menus from the plurality of cooking menus by performing a displacement operation in a predetermined direction and which can be pressed; The cooking menu selected by the displacement operation is set, and when the input operation by the pressing operation is performed after the stop period of the displacement operation of the operation member has continued for a certain period of time or more, heating is performed according to the set cooking menu by receiving the input. Control means for executing cooking, wherein the control means performs the cooking menu selection operation when a displacement operation of the operation member is equal to or more than a predetermined amount in a state of receiving a pressing operation by the operation member. It has features in its configuration.

[0010]

According to the cooking device of the present invention, one cooking menu can be selected from a plurality of cooking menus by displacing the operation member in a predetermined direction. The setting is made by the control means for heating and cooking. Then, when the state in which the operating member is not displaced for a certain period of time or more continues, the control means is in a state of receiving an input of cooking start by a pressing operation of the operating member.
In this state, when the operation member is pressed, the control unit executes the heating cooking of the set cooking menu.

At this time, when the control means is in a state of receiving the input of the start of cooking by the pressing operation of the operation member, the control means receives the input only when the operation member is displaced by a predetermined amount or more and selects the cooking menu. Since the operation is performed, even when the operation member is erroneously displaced when the operation member is pressed, if the amount of displacement is small and equal to or less than the predetermined amount, the set cooking menu is not changed.

Conversely, when the cooking menu is changed and set in the above-described state, the selection operation can be performed again by displacing the operation member by a predetermined amount or more. Therefore, the selection operation by the displacement operation and the pressing operation of the operation member and the operation of starting the cooking become easy, and the usability is improved.

The provided magnetron 3 (see FIG. 1) is oscillated to heat and cook an object to be heated in the cooking chamber 2. Further, at the time of oven cooking or grill cooking, an object to be heated in the heating cooking chamber 2 is heated and cooked 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 cooking chamber 2 is provided on the front of the outer box 1, and an operation panel 7 is provided on the front of the machine room. This operation panel 7
As shown in FIG. 3, a display unit 8 for displaying time, a cooking setting state, and the like, and a menu display unit 9 for displaying a large number of cooking menus are provided as display means.

The menu display section 9 is divided into a plurality of cooking menu groups 9a, 9b, 9c, each of which displays a plurality of cooking menus. As will be described later, when a display output is given, one of the cooking menu groups 9a to 9c is lit and displayed, and the corresponding cooking menu is lit and displayed. .

An operation dial 10 as an operation member disposed below the menu display section 9 is configured to be capable of being displaced in a predetermined direction, clockwise and counterclockwise, and capable of being 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), whereby the plurality of cooking menus displayed in the cooking menu groups 9a, 9b, 9c are displayed. One of the desired cooking menus can be selected. On the other hand, this operation dial 10
Is pressed, a signal for starting heating and cooking is input to the control circuit 11.

An operation key 12 for selecting a cooking menu by manual operation is provided below the operation dial 10. The operation keys 12 include, for example, key switches 12a, 12b, 12c, etc., so that a desired cooking menu can be selected.

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

The control circuit 11 supplies the magnetron 3, the oven heater 4 and the grill heater 5 with a drive signal via the respective drive circuits 3a, 4a and 5a in accordance with the set heating and cooking conditions so as to perform heating. Cooking is to be performed.

Next, the operation of the present embodiment will be described with reference to FIGS.

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

The control circuit 11 detects a rotation direction and a rotation displacement amount based on a signal from the operation dial 10 by executing a program (not shown). In this case, the control circuit 11 adjusts the rotation angle to the right. Cooking menu group 9 according to
Display signals are sequentially applied to a to 9c. Thereby, the cooking menu groups 9a to 9 to which the display signal is given are provided.
c are sequentially displayed, and the cooking menu groups 9a and 9 corresponding to the user's rightward rotation of the operation dial 10 are displayed.
b and 9c are selected.

Next, when the operation dial 10 is rotated leftward, the control circuit 11 similarly detects the leftward rotation angle and selects one of the cooking menu groups 9a to 9c according to the value. The cooking menu is sequentially displayed from the items in the displayed state.

As described above, the user operates the operation dial 10
Menu menu 9a by rotating the menu item to the right.
One of the plurality of cooking menus in the selected cooking menu group 9a to 9c can be selected by selecting and setting one of the cooking menus from among the cooking menus 9a to 9c. As a result, one desired cooking menu can be selected and set from a plurality of cooking menus with a simple operation.

When the cooking menu is selected and set as described above, the control circuit 11 reads out the heating condition of the cooking menu according to the setting state from the memory and sets it. Then, when a state in which the selection operation of the cooking menu is not performed by the rotation operation of the operation dial 10 has elapsed for a predetermined time T, the input of the cooking start by the pressing operation of the operation dial 10 can be accepted.

Accordingly, when the operation dial 10 is pressed thereafter, the control circuit 11 receives the input of the start of cooking and executes the heating cooking corresponding to the set cooking menu.

When the operation of rotating the operation dial 10 for selecting a cooking menu is performed again before the predetermined time T has elapsed, the control circuit 11 controls the operation of the operation dial 10 according to the operation of rotating the operation dial 10. The operation of selecting a cooking menu is performed.

Next, for example, after the user selects and sets a desired cooking menu, when the operation dial 10 is pressed while the predetermined time T has elapsed, the user turns the operation dial 10 by mistake. With reference to the flowchart of the program shown in FIG. 4, an operation in the case of changing the cooking menu selected or set will be described.

FIG. 4 shows a part of the program steps performed when the control circuit 11 executes a program including the above-described cooking menu selection operation. The control circuit 11 first determines in step S1 whether or not it is in the state of accepting the start of cooking.
When the selection operation of the cooking menu is performed by the rotation operation of the operation dial 10, the state is not in the acceptable state, so “NO” is determined and the process proceeds to step S 2.

Next, the control circuit 11 controls the operation dial 10
Is operated in step S2, "YE
In step S3, the cooking menu selection operation is performed, and the heating cooking conditions of the selected cooking menu are read from the ROM and set. Thereafter, the control circuit 11 starts a timer function in step S4, and starts a time counting operation for a time t until the operation dial 10 is rotated next time.

Thereafter, the control circuit 11 executes a program (not shown) and then returns to step S1. If the time t measured by the timer function has not reached the predetermined time T, the control circuit 11 determines "NO" and proceeds to step S2. When there is no rotation operation of the operation dial 10, "N
If the determination is "O", the process proceeds to step S5. Here, since the clock time t has not reached the predetermined time T, the determination is "NO" and the process proceeds to a program (not shown).

Then, while repeating the above-described program, the control circuit 11 determines "YES" in step S5, that is, when the time t becomes equal to or longer than the predetermined time T,
The process proceeds to step S6 to enter a cooking start acceptance state. That is, in this state, as described above, when there is an input of cooking start by pressing the operation dial 10, the control circuit 11 is in a state of receiving the input.

Thus, when the control circuit 11 returns to step S1, it determines "YES" and shifts to step S7, where it determines whether or not a pressing operation input of the operation dial 10 has been performed. At this time, when the operation dial 10 is pressed, the control circuit 11 executes step S
Then, the process proceeds to step S8 to execute the heating cooking under the heating cooking condition corresponding to the set cooking menu. FIG. 5 shows the state of the signal output corresponding to the turning operation of the operation dial 10.

Thus, the control circuit 11 determines in step S1
If it is determined “YES” and the process proceeds to step S7, and if the operation dial 10 is not pressed, “NO” is determined here and the process proceeds to step S9. The control circuit 11 determines in step S9 that the operation dial 1
If 0 has not been rotated, it is determined to be "NO" and the process proceeds to a step not shown. If it has been rotated, it is determined to be "YES" and the process proceeds to step S10.

Now, in step S10, the control circuit 11
Determines whether the operation dial 10 has been turned by a predetermined angle or more. For example, at this time, the operation dial 10
Is rotated by a predetermined angle or more, the control circuit 11
Determines that the user has performed a rotation operation to change the selected cooking menu, determines “YES”, and shifts to step S11 where the input of the start of cooking by pressing the operation dial 10 is prohibited. State. FIG. 6 shows a state of signal output according to the turning operation of the operation dial 10 as described above.

On the other hand, when the user selects the desired cooking menu and then turns the operation dial 10 to execute heating cooking, for example, when the user turns the operation dial 10 slightly by mistake, or the like. Since the rotation operation amount does not normally reach the predetermined angle, the control circuit 11 determines “NO” and proceeds directly to a step not shown.

Therefore, after this, the user operates the operation dial 1
0, the control circuit 11 returns to step S
When step S7 is reached after step 1, it is determined to be "YES" and heating cooking is executed (step S8).

According to the present embodiment, when the cooking menu is selected by rotating the operation dial 10 and the predetermined time T elapses and the input of the cooking start by the pressing operation becomes possible, The control circuit 11 accepts the selection operation of the cooking menu only when the operation dial 10 is rotated by a predetermined angle or more, so that the cooking starts after a certain time T has elapsed after the selection operation of the cooking menu is completed. When the operation dial 10 is pressed to input "!", Even if the operation dial 10 is slightly rotated by mistake, the set cooking menu is not changed, and the usability is improved for the user. Become like

In the above embodiment, the operation dial 10 for selecting the cooking menu by the rotation operation is provided. However, the present invention is not limited to this. For example, an operation member that is operated to be displaced in a linear direction is used. It can also be.

In the above embodiment, a plurality of cooking menus are selected and divided into the cooking menu groups 9a, 9b and 9c. However, the present invention is not limited to this. A plurality of cooking menus may be sequentially displayed and selected according to the rotation by a rotation operation.

[0042]

As described above, according to the heating cooker of the present invention, when a displacement operation of the operating member is performed by a predetermined amount or more in a state where the pressing operation by the operating member is received by the control means. Since the configuration is such that the cooking menu selection operation is performed, when a desired cooking menu is selected and set by the displacement operation of the operation member and a predetermined time has elapsed, and then the heating cooking is executed by the pressing operation, for example, a small error may occur. Even if only the displacement operation has been performed, the selection operation of the cooking menu is not performed unless the displacement amount has reached a predetermined amount or more, so the user does not have to perform the setting again,
Heat cooking can be executed, and an excellent effect that usability is improved is exhibited.
