Abstract

PURPOSE:To provide a stable finished state of cooking irrespective of a duration of interruption time by a method wherein there are provided an interruption key, a start key and a control device. CONSTITUTION:A user operates an interruption key 5c and instructs an interruption of heating operation and then the heating operation is stopped while a remaining time is stored. Then, when a restarting of the heating operation is instructed in response to an operation of a start key 5a, the heating operation corresponding to the remained heating time is executed and at this time the interruption time of the heating operation is counted and the remaining time is corrected in response to the interruption time. Accordingly, the user can easily interrupt the heating operation and at the same time an instruction of restarting can be satisfactory only with an operation of the start key 5a, resulting in that its operation can be simplified. Then, since the correction of the remained heating time corresponding to the interruption time is carried out when the heating operation is restarted, it is possible to make a stable finished state of cooking for both of long interruption time and short interruption time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker such as a microwave oven for performing a heating operation on a food item in a predetermined cooking mode including a heating time.

[0002]

2. Description of the Related Art For example, in a microwave oven, a magnetron, a heater, etc. are controlled by a control device in a predetermined cooking mode according to a cooking menu based on a user's selection operation of the cooking menu on an operation panel. The heating operation for the food is automatically performed. In this case, the heating operation is executed in the heating time according to the setting of the user or by the automatic setting.

By the way, some cooking menus, such as stewed foods and stewed foods, have a long heating time of about 2 hours. For example, while cooking for a long time like this,
When the user wants to cook for another short time, conventionally, after the user operates the cancel key to stop the stew cooking on the way and perform another short time of cooking. However, a troublesome operation such as resetting the cooking mode for the stewed cooking and executing the heating operation for the remaining time was required.

[0004]

Therefore, in recent years, as shown in Japanese Patent Laid-Open No. 63-231120, a cooking interruption key is provided in addition to the cancel key, and the user presses the cooking interruption key during cooking. When turned on, cooking is interrupted at that point to allow other cooking to be interrupted, and the state at the time of interruption (heating output, remaining time, etc.) is stored, and then based on the stored state. A configuration is being considered in which the rest of the cooking is restarted.

However, in such a configuration, since the heating operation of the fixed predetermined heating time is simply executed in a plurality of times with the interruption, the interruption operation may be long or short. There was a problem that the quality of cooking changed.

The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to easily suspend and restart cooking, and to show the cooking condition regardless of the length of the suspension time. It is to provide a heating cooker that can stabilize the satisfactorily.

[0007]

The cooking device according to the present invention comprises:
An interruption instruction means for instructing interruption of the heating operation, a heating operation interruption means for stopping the heating operation in a state in which the remaining heating time is stored based on the operation of the interruption instruction means, and a cook for which the heating operation is interrupted Resuming instruction means for instructing restart of the heating operation, time measuring means for measuring the heating interruption time for the cooked food whose heating operation is interrupted, and correction of the remaining heating time according to the interruption time measured by this time measuring means And a heating operation restarting means for executing a heating operation for the remaining heating time corrected based on the operation of the restart instruction means.

Further, in this case, when the interruption time is within a predetermined time, the heating time correction means performs a correction for adding a correction time having a length corresponding to the length of the interruption time to the remaining heating time, When the interruption time exceeds a predetermined time, it is possible to perform correction by adding a correction time of a fixed length to the remaining heating time.

[0009]

According to the above means, when the user operates the interruption instruction means to instruct the interruption of the heating operation, the heating operation interruption instruction means stops the heating operation while the remaining heating time is stored. It Then, when the restarting of the heating operation is instructed based on the operation of the restart instruction means, the heating operation restarting means executes the heating operation for the remaining heating time. The time is measured, and the heating time correction means corrects the remaining heating time according to the interruption time.

Therefore, the user can easily interrupt the heating operation, and the operation of resuming the heating operation can be made extremely simple because the restart instruction only needs to be operated by the restart instruction means.
When the heating operation is restarted, the remaining heating time is corrected according to the interruption time instead of simply performing the cooking operation for the remaining time, so cooking can be performed depending on whether the interruption time is long or short. It is possible to stabilize the condition.

Further, in this case, if the correction time of the length corresponding to the length of the interruption time is corrected to be added to the remaining heating time, the cooking quality can be stabilized. However, if the discontinuation time becomes longer than a certain amount, the food will be completely cooled, and the correction time for stabilizing the cooking condition is considered to be almost constant regardless of the discontinuation time. If the correction time is extended indefinitely, on the contrary, the quality of cooking will deteriorate and the time will be wasted. Therefore, when the interruption time exceeds the predetermined time, it is sufficient to stabilize the cooking condition by adding the correction time of a certain length to the remaining heating time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a microwave oven will be described below with reference to the drawings. First, the configuration of the microwave oven will be briefly described with reference to FIGS. 2 and 3. FIG. 2 shows an appearance of a main body 1 of a microwave oven which is a heating cooker. The main body 1 has a rectangular box shape, and a front surface of a cooking chamber accommodating an unillustrated food item can be seen through. A cover 2 is provided so as to be openable and closable, and an operation panel 3 is provided on the right side thereof.

As shown in FIG. 3, the operation panel 3 is provided with a display portion 4 at the upper portion and various operation keys 5 at the lower portion for selecting and instructing a cooking mode. There is. Although not shown in detail, the display unit 4 digitally displays the heating time (remaining time required for cooking), and character display of the heating mode (raw thawing, strong / weak range, oven, etc.). It is like this.

Although not shown in detail, the operation keys 5 include an automatic cooking key for selecting an automatic cooking menu, a manual cooking key for the user to select a heating mode, and a manual cooking. A time setting knob for the user to set the heating time, a start key 5a for starting heating and cooking, a cancel key 5b, an interruption key 5c for interrupting the heating and cooking operation, etc. are provided at times. Of these, the interruption key 5c is for interrupting the heating operation during heating and cooking, and functions as interruption instruction means in the present invention. Further, the start key 5a also functions as a restart instruction means according to the present invention for instructing restart of the interrupted cooking.

On the other hand, although not shown in detail, in the machine room provided in the main body 1, a magnetron or the like for supplying microwaves to the cooking room to perform range cooking is provided.
Further, a heater and the like for performing oven cooking are provided in the cooking chamber. These heating sources such as magnetrons and heaters are driven by the heating circuit 6.

As shown in FIG. 3, the main body 1 is provided with a control device 7 mainly composed of a microcomputer. The control device 7 is configured to have a timer function as a memory and a time measuring means,
Based on the operation of each operation key 5 of the operation panel 3, the heating circuit 6 and the like are controlled in accordance with a built-in cooking program, so that the heating operation of the cooked food contained in the cooking chamber is executed. It has become.

In this case, when automatic cooking is selected by the automatic cooking key of the operation panel 3, the control device 7
The heating mode is automatically set according to a pre-stored automatic cooking program, and the heating time is automatically set based on the detection of a weight sensor (not shown) or the like, and the automatic cooking is executed. On the other hand, when the user operates the manual cooking key, the heating operation according to the selected heating mode is executed based on the heating time set by the user operating the time setting knob.
Further, the control device 7 is configured to display the heating mode and the heating time (remaining heating time) on the display unit 4 of the operation panel 3.

By the software configuration of the controller 7, when the interrupt key 5c is operated during the heating operation, the heating operation is performed while the remaining heating time T1 at that time and the heating mode are stored in the memory. It is stopped and the interruption execution of other cooking is allowed. When the restart key 5a is instructed to resume cooking,
The stored heating mode or the like is read and the heating operation for the remaining heating time is executed. This makes it easy to interrupt the heating operation without the user having to reset the settings.
It can be restarted.

Then, as will be apparent from the description of the flow chart below, the control device 7 measures the interruption time t from when the interruption key 5c is operated to when cooking is restarted, and restarts cooking. At this time, the remaining heating time is corrected according to the interruption time t. Therefore,
The control device 7 functions as a heating operation interrupting means, a clocking means, a heating time correcting means, and a heating operation restarting means according to the present invention.

Further, in the present embodiment, the heating time is corrected by adding the correction time Th corresponding to the interruption time t to the stored remaining heating time T1. At this time, As shown in FIG. 4, when the interruption time t is within a predetermined time of 30 minutes, the interruption time t
The correction time Th (Th = t × 1/3) proportional to is added to the remaining heating time T1, and when the interruption time t exceeds 30 minutes, the correction time Th (Th = 10 minutes) of a constant length is added. A correction for adding to the remaining heating time T1 is performed.

Next, the operation of the above configuration will be described with reference to FIG. In the flowchart of FIG. 1, for example, while stew cooking of stew or the like having a long heating time (referred to as first cooking) is being performed, the first cooking is interrupted and other cooking having a relatively short heating time is performed. The processing procedure of the control apparatus 7 in the case of interrupting (referred to as second cooking) and then restarting the first cooking is shown.

That is, when the food to be cooked for the first cooking is accommodated in the cooking chamber and the cooking mode (heating time, heating mode, output, etc.) is set, and the start key 5a is operated (Yes in step S1). ), The heating operation is started in the cooking mode (step S2). During the execution of this heating operation, the countdown of the set heating time is performed,
The remaining heating time is displayed on the display unit 4.

If the user wants to interrupt the second cooking during the execution of the first cooking, the interruption key 5c is pressed.
Is operated (Yes in step S3). Then, the heating operation is stopped (step S4), and the remaining heating time T1 regarding the first cooking, the heating mode and the output, etc. are stored in the memory (step S5). Further, the timer starts counting operation from this point (step S6).

Here, when the user cancels the execution of the second cooking for some reason, he or she operates the cancel key 5b (Yes in step S7), and the heating operation after step S13 is restarted. . When the user wants to perform the second cooking, the user stores the food in the cooking chamber, selects the cooking mode, and operates the start key 5a (Yes in step S8). Then, the heating operation of a predetermined heating mode is performed (step S9), and unless the cancel key 5b is operated (N at step S10).
o) When the heating operation for the set heating time is continued and the heating operation for the heating time is completed (step S
11, the heating operation is stopped (step S).
12).

When the heating operation for the second cooking is completed in this way, in step S13, the remaining heating time T1 relating to the first cooking and the heating mode and output stored in the memory are read out and displayed on the display unit. 4 is displayed.
Then, the correction time Th is obtained from the timed interruption time t (step S14), and the remaining heating time is corrected (step S15). As described above, the correction time Th is obtained according to FIG. 4, and the heating time T is
It is corrected and set by adding the correction time Th to the stored remaining heating time T1.

Thereafter, by operating the start key 5a (Yes in step S16), the heating operation for the first cooking is restarted (step S17). Also in this case, unless the cancel key 5b is operated (No in step S18), the heating operation for the set heating time T is continued, and when the heating operation for the heating time T ends (Yes in step S19). The heating operation is stopped (step S20). In this way, the heating cooking for the first cooking which has been once interrupted is completed.

As described above, according to this embodiment, the user
The heating operation of the first cooking can be easily interrupted by operating the suspend key 5c, and the restart instruction can be given only by operating the start key 5a, and it is not necessary to set the cooking mode again when restarting. , Its work becomes extremely easy. Then, when the heating operation is restarted, the remaining heating time is corrected (heating time T) according to the interruption time t, instead of simply performing the cooking for the remaining heating time T1, so that the interruption time t is long. And when the length is short, it is possible to stabilize the quality of cooking in a good condition.

By the way, the interruption time t is a predetermined time, for example, 3
When the time exceeds 0 minutes, the food is completely cooled, and it is considered that the correction time Th for stabilizing the cooking condition is almost constant regardless of the interruption time t, and the correction time Th is unlimited. On the other hand, if the length is made too long, the cooking quality will be poor and the time will be wasted. On the other hand, in the present embodiment, when the interruption time t is within 30 minutes, the correction time Th proportional to the interruption time t is added to the remaining heating time T1, and when the interruption time t exceeds 30 minutes, it is constant. Since the correction time Th (10 minutes) of the length is added to the remaining heating time T1, the correction is performed.
It is enough to stabilize the cooking quality.

In the above embodiment, the remaining heating time is corrected by the relationship between the interruption time t and the correction time Th shown in FIG. 4, but the relationship shown in FIG. The remaining heating time may be corrected based on that, and the correction is not limited to the method of adding the correction time Th, and the remaining heating time is multiplied by a coefficient according to the interruption time. A method is also possible.

In addition, a cooking restart key as a restart instruction means may be separately provided on the operation panel.
The present invention can be appropriately modified and implemented within the scope of the gist.

[0031]

As is apparent from the above description, according to the heating cooker of the present invention, when an instruction to interrupt the heating operation is given, the heating operation is stopped while the remaining heating time is stored and the heating operation is stopped. When the operation is restarted, the remaining heating time is corrected according to the interruption time, and the remaining heating operation is executed, so that the cooking operation can be interrupted and restarted easily. Regardless of the size, it has an excellent practical effect that the cooking quality can be well stabilized.
