Abstract

PURPOSE:To make it possible to restart cooking at a suspended portion, if an attempt is made to restart cooking operation within a specified time, even when cancellation is made by mistake by providing a cooking returns acceptance means which is capable of suspending cooking and restarting said cooking at the suspended portion within a specified time. CONSTITUTION:When a cancel switch 8c is manipulated during cooking, a microcomputer 22 judges whether or not present cooking a cooking based on several processes, say, bread making or bread dough making, and if the checked cooking is found different from bread making and bread dough making, the microcomputer 12 cancels the cooking at that detected time. In case of bread making or bread dough making, a microcomputer 20 once suspends the cooking, and stores execution process and execution time spent up to that time and sounds a buzzer 26 as an annunciator. The computer 22 counts the lapse of time T since the cancel key switch 8c is manipulated, and judges whether or not the time T exceeds cooking return allowable time t0.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention consists of a plurality of strokes controlled by a control device. 2! The present invention relates to a cooking device that automatically performs J-processing, and particularly relates to control for canceling automatic cooking consisting of multiple steps.

(Prior Art) Some cooking appliances, such as microwave ovens, are equipped with a bread-making program as one of the automatic cooking programs. In this device, when bread production is selected by operating a key switch, multiple steps from kneading dough to baking are automatically performed, and bread is automatically produced.

On the other hand, in a microwave oven, a canceling key switch is provided in the operating section, and by operating this canceling key switch, it is possible to stop cooking in progress.

(Problems to be Solved by the Invention) In the above-mentioned conventional microwave oven, if the cancel key switch is accidentally operated during cooking, the cooking will be stopped midway. In this case, for example, if the cooking involves simple heating, such as boiling side dishes or warming rice, even if the cooking is stopped midway due to an error, you can manually set the appropriate cooking time and restart it. That's all you need to do.

However, if the cancel key switch is accidentally operated during bread making, delicious bread cannot be made and the dough is wasted. That is, if the cancel key switch is operated by mistake during bread production, the bread production will be stopped. Therefore, if you realize that you have made a mistake and restart the operation, bread production will start from the first step, that is, the dough kneading step. For example, if you cancel during the kneading step, the kneading will start again from the beginning. As a result, the dough is kneaded too much, making it impossible to make delicious bread, and, for example, if the baking process is stopped during the baking process, it will be kneaded again, resulting in the dough itself being wasted.

Therefore, if the user accidentally cancels the operation during bread making, the bread dough must be taken out and kneaded by hand, and the rest of the bread making must be done manually.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a cooking device that does not cause the possibility of accidentally stopping cooking consisting of a plurality of steps.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object 1, the cooking appliance of the present invention automatically executes cooking consisting of multiple steps under the control of a control means. , when a cancellation operation is performed during the execution of cooking consisting of a plurality of steps, the cooking is interrupted, and then the cooking 1 starts from the interrupted part within a predetermined period of time.
(2) A cooking return permitting means is provided to enable opening.

Further, when cooking is interrupted due to a cancellation operation, it is preferable that the notification means is operated within a predetermined period of time until cooking is restarted.

(Function) According to the above means, even if a cancellation operation is performed by mistake during execution of automatic cooking consisting of multiple steps, if the cooking restart operation is performed within a predetermined time thereafter, cooking will be resumed from the interrupted part. .

Moreover, since the notification means performs a notification operation when a cancellation operation is performed, in the event of an erroneous operation, it is possible to immediately perform an operation to restart cooking.

(Embodiment fF1) An embodiment in which the present invention is applied to a microwave oven will be described below with reference to the drawings.

The overall configuration of the microwave oven is as shown in Figure 2, and inside the main body 1! A heating chamber 3 is formed which is opened and closed by i12,
A high frequency wave emitted from a magnetron 4 shown in FIG. 4 is supplied into the heating chamber 3.

Further, a bread making container 5 is removably attached to the bottom of the heating chamber 3.

Although not shown, a kneading blade is provided inside this container 5, and this kneading blade is rotationally driven by a motor 6 shown in FIG. 4 disposed inside the main body l.

On the other hand, a key switch group 8 is provided in the drying section 7 at the front of the main body 1, and as shown in FIG. Bread key switch 8a, bread dough key switch 8b for selecting automatic cooking for bread dough production, canceling selected cooking or changing cooking mode 11. Cancellation key switch 8c.

, 7! There is a start key switch 8d for starting J-processing.

The main electric circuit configuration of the microwave oven configured as described above is as shown in FIG.
a is connected to a commercial power source 14 via a relay switch 10, two door switches 11 and 12 that are opened when the door 2 is opened, and a fuse 13. Further, a monitor switch 15 that is closed when the door 2 is opened is connected between the door switches 11 and 12 connected to one bus bar of the commercial power source 14 and the other bus bar of the commercial power source 14. Further, a relay switch 16 and the motor 6 for driving the cross-conducting blade are connected in series between the I switch 11 and the relay switch 10 and the other bus bar of the commercial power supply 14. An electric oven heater 17 and a relay switch 18 are connected in series. on the other hand,
A voltage doubler rectifier circuit consisting of a high voltage capacitor 19 and a high voltage rectifier 20 is constructed on the secondary winding 9b side of the high voltage transformer 9, and its DC output is connected to the anode of the magnetron 4.
It is designed to be applied between the cathodes. Note that the anode of the magnetron 4 is grounded, and the heater is connected to the heater winding 9C of the high voltage transformer 9.

Next, the control circuit 21 for controlling the entire microwave oven will be described. This includes a microcomputer 22 as a control means, receives signals from the key switch group 8, etc., and receives signals from the relay switch 10.
．． 16. Relay coil 23 for opening and closing operation of 18
~ 25 is de-energized. That is, when the user operates a key switch to select a desired cooking and then operates the start key switch 8d, the relay coils 23 to 25 are energized depending on the content of the selected cooking, and the magnetron 4, The motor 6 and electric heater 17 are energized, and a so-called electronic buzzer 26 is driven when necessary. Incidentally, the microcomputer 22 also functions as a cooking return permitting means, as will be clear from the explanation of its function below.

Among the cooking controlled by the microcomputer 22, bread production, bread dough production, etc. are controlled by the microcomputer 22 according to programs stored in the memory. Here, when na cooking of bread is produced, three well-known steps shown in the process chart of FIG. 5 are automatically proceeded in order. this house,"
The "kneading" process is performed by rotating the kneading blades in the container 5 using the motor 6, and the "fermenting" and "baking" processes are performed by energizing the electric heater 17 to make the inside of the heating chamber 3 suitable for fermenting and baking the dough. This is done by maintaining the temperature. In addition, when bread dough production is selected, everything from kneading to fermentation is automatically proceeded.

Next, in the above configuration, the operation of the cancellation key switch 8C during cooking will be explained with reference to the flowchart of FIG.

This explanation of the operation should make clear the function of the microcomputer 22 as a cooking return permitting means.

First, the user sets the desired cooking content by operating the key switch, and then operates the start key switch 8C. Then, the set cooking is executed.

Now, when the cancel key switch 8C is operated during the execution of this cooking, the microcomputer 22 first determines whether the set cooking is multi-step cooking, that is, bread making and bread dough making in this embodiment. Decide (step a). For cooking other than bread making and bread dough making,
The microcomputer 22 stops cooking at that point and returns to the initial state, that is, a state in which a new cooking to be performed can be set (step b).

In addition, when the cooking being executed is bread making or bread dough making, the microcomputer 20 temporarily interrupts the cooking and updates the content of the execution at the time of interruption, specifically, the execution process and up to that point. and the execution time (step C). The microcomputer 22 then drives the buzzer 26 as a notification means to make it sound (step d). Next, the microcomputer 22 counts the elapsed time T since the cancellation key switch 8c was operated, and this elapsed time T becomes the preset cooking return allowable time t. (for example, 10 seconds) (step e).

Here, if the cancel key switch 8c is operated by mistake, the user notices the erroneous operation and immediately operates the start key switch 8d. At this time, since the buzzer 26 is sounding, it is possible to reliably notify that the user has made an erroneous operation. Then, the allowable cooking return time t. When the start key switch 8d is operated, the microcomputer 22 stops the buzzer 26 and resumes cooking from the memorized execution contents at the time of interruption (step f). Further, the elapsed time T from the time when the cancellation key switch 8c is operated is the allowable cooking return time t. If the microcomputer 22 exceeds the buzzer 26, the microcomputer 22
At the same time, the cooking is stopped and the initial state is restored (step g).

As described above, according to this embodiment, if a cancellation operation is performed while bread manufacturing or bread dough kneading is being performed, the cooking is interrupted at that point, but the process is continued for a predetermined period of time t.
If the start key switch 8d is operated within 0, the cooking will resume from the interrupted part, so there will be no problem such as stopping halfway due to an erroneous operation and wasting bread dough.

Incidentally, in the above embodiment, bread making and bread dough kneading were exemplified as cooking consisting of a plurality of steps, but the application of the present invention is not limited to this, and various other methods can be considered. For example, when thawing frozen perishables, we run multiple processes with different heating conditions, specifically multiple processes in which the output of the magnetron decreases in order. It may also be applied to automatic thawing cooking. Furthermore, the notification means may be one that lights up a lamp. In addition, the present invention is not limited to microwave ovens, but can be widely applied to cooking appliances that automatically perform cooking consisting of multiple steps.

[Effects of the Invention] As is clear from the above description, the invention provides the following excellent effects.

According to the invention described in claim 1, when a cancel operation is performed during execution of cooking consisting of a plurality of steps, the cooking is interrupted and the cooking 11 start + 'iJ function is then restarted from the interrupted part within a predetermined time. By providing a means for allowing cooking to return to cooking, if the cooking is interrupted due to an erroneous operation during cooking,
There is no risk of letting it happen.

Further, according to the invention as claimed in claim 2, by providing a notification means that performs notification operation within a predetermined time after a cancellation operation is performed until cooking is resumed, it is possible to notify that cooking has been interrupted, thereby preventing erroneous operation. In such a case, the user can be prompted to restart cooking.
