Abstract

PURPOSE:To eliminate uneven thawing by providing a signalling means of desired number of times of processing food. CONSTITUTION:Buzzer signalling is performed while being thawed and cooked as many times (n) as optimum for the weight information at moments responsive to afore-said times (n). When a cook hears the buzzer signalling, he or she opens the door 2 to do whatever necessary processing such as turning over the food for the second time, for example. When the door 2 is closed and the start key is operated, the thawing and cooking are resumed in accordance with the program. When the reading of the interruption interval counter reaches to the reading of the interruption interval register PT thereafter, the thawing and cooking process is terminated. Then, key information for the following cooking can be inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION B) Industrial Application Field The present invention relates to an electronically controlled cooking device, and can be used in, for example, a microwave oven.

(B) Prior Art In recent years, many microwave ovens equipped with a control unit consisting of a microprocessor or the like have been commercialized, and such microwave ovens are capable of performing complex cooking. For example, thawing cooking as shown in Japanese Patent Application Laid-Open No. 57-80693 can be carried out. During such defrosting cooking, the microwave output is changed in order to prevent uneven defrosting as much as possible.

(c) Problems to be Solved by the Invention The present invention solves the problem that uneven thawing occurs by a method other than such output control or by a method that can be combined with such output control. The aim is to significantly suppress the
This method allows the cook to perform desired processing such as changing the position of the food, turning the food over, etc. during cooking, such as defrosting. Therefore, in such a case, measures should be taken to notify the cook of the time when the above-mentioned process is to be performed. Furthermore, the number of times the desired treatment is applied should be determined by the weight of the food product.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a heating energy generating means for generating heating energy for heating food, and controlling the drive of the generating means for cooking. In the electronically controlled cooking appliance, a number processing section is provided in the control section for processing information regarding the number of times to perform the desired processing on the food during the cooking, and the processing section performs the desired processing. A notification means for notifying the time and a weight setting section for setting weight information of the food are provided, the control section is configured to operate, and the number processing section is configured to set the number of times based on the weight information from the weight setting section. The apparatus is characterized in that an appropriate point in the cooking process is determined based on the number of times the cooking process is performed, and that the notification means is activated when the cooking process reaches such a point.

(e) Effect: According to such a configuration, it is possible to automatically notify the cook when to perform desired processing such as changing the position of the food or turning the food over in order to eliminate uneven thawing. . Furthermore, the number of times the desired treatment is performed can be automatically and optimally determined based on the weight of the food.

(v) Example A microwave oven according to an example of the present invention will be described below with reference to the drawings.

Figure 2 shows the appearance of the microwave oven.
) has a heating chamber (3) whose front opening is opened and closed by a door (2) and which stores food, and is located incorrectly within the main body (1).
) is provided with a panel section (4) on the front right side.

FIG. 3 shows the details of the panel section (4), which has a fluorescent display (5) for displaying cooking time, etc.
) and a keyboard (6) for setting weight, cooking time, output, etc.

FIG. 4 shows the circuit of the microwave oven, and the microwave oven is equipped with a microprocessor (7) as its control unit, and the processor controls the display (5) based on information from the keyboard (6>). In addition to controlling the display, the output of the heating signal HEAT and the buzzer signal BZ is also controlled.
The switching circuit (8) consisting of a bidirectional cyrisk is turned on, and then power is supplied from the commercial power supply (9) to the high voltage circuit (10>), thereby driving the magnetron (11) as a means for generating heating energy, and the above-mentioned heating Microwaves for heating food are supplied to the chamber (3). Also, when the buzzer signal BZ is output, the buzzer drive circuit (12)
is activated, and a buzzer (13) as a notification means sounds.

FIG. 5 shows the flow of the program of the processor (7), and the operation of the microwave oven will be explained below in accordance with this flow. Prior to that, an outline of the operation will be first described in accordance with FIG.

The figure relates to thawing cooking. Once the food weight information has been set by the cook, the thawing time t is determined by referring to a predetermined weight chart as seen in Japanese Patent Application No. 53-1589 (No. 52). 1. The thawing cooking can be divided into a first stage of time tz (= t 60%
The power output is 0W, and the second stage is 300W, which is 50%. Furthermore, the optimal number of times n based on the above weight information is solved at the time corresponding to the number of times n! A buzzer will sound while cooking.

That is, the buzzer is notified 0 times at Pl, P2, . . . Pn every P t [-t'/(n + 1) time.

In this case, as the optimal number of times n, the weight information is 1 to 2-
When it is bond, it is 1.3 to 5 bond, and when it is 2.6 bond or more, it is 3. Then, the cook can easily check the timing of performing desired processing, such as changing the position of the food or turning the food over, by such notification, and can carry out such processing. In this way, defrosting cooking can be carried out while minimizing the occurrence of uneven defrosting. In this case, the thawing cooking is interrupted every time the above-mentioned points are reached.

Now, the operation of the microwave oven will be explained according to FIG.

When the microwave oven is powered on, the program normally cycles through steps S2 and S3 via step S1.

In the S1 step, the writable area in the processor (7) is cleared, and in the S2 step, the keyboard (6>
In step S3, key information that allows new key operations to be completed is input, and in step S3, it is determined whether or not the key operations have been completed based on the key information in step S2.

For example, when defrosting and cooking 3-bond meat,
The key operations on the keyboard (6) are as follows.

First, when you operate the decompression key, the program will proceed to step S2 above.
The cycle exits from the S3 step and reaches the S4 step. In this step, it is determined whether the key information in step S2 is related to decompression. The present case concerns decompression, and the program then cycles through steps S5 to S8. If decompression is not involved, the program proceeds to the appropriate step.

Then, in step S5, the weight information of the food is displayed on the display (5) by referring to the contents of the weight register QTT in the processor (7>). Therefore, '1.OJ' is displayed on the display (5).The S6 step is the same as the above S2 step, and in the S7 and S8 steps, the key information in the S6 step is the numeric key and the start key. It is determined whether the information is information or not.

Next, when you operate the number key 3 corresponding to the weight 3 bond, the program cycles through steps 85 to S8 above to 87.
Exit the step and proceed to step 87-1. In this step, the weight register QTT is set to 3, and then the program cycles through steps 85 to S8 again, during which time the display (5) shows '3. OJ is displayed.

When the start key is operated, the program advances to step S9. In this step, the RO in the processor (7)
Patent application No. 53-158962 stored in the M area in advance
With reference to Char 1. on weight as seen in No.
The decompression time is determined and set in the decompression time counter DT in the processor (7). That is, in this example, the standard thawing time of 5 minutes corresponding to the standard amount of 1 bond is multiplied by the weight of the contents of the weight register QTT, which in this case is 12 minutes and 30 seconds, which is the result of multiplying the coefficient 2.5 corresponding to 3 bonds. is set in the defrosting time counter DT.

In the next 310 steps, the time obtained by multiplying the contents of the defrosting time counters D and T by 0.3 (in this case, 0.3 x 12 minutes 30 seconds = 3 minutes 45 seconds) is calculated as the first stage counter in the processor (7). Can be set to DTI.

The program continues to step 311. In this step, it is checked whether the contents of the weight register QTT are 2 bonds or less. Here, the answer is no, so the program then proceeds to step 911-1. In this step, it is further checked whether the contents of the weight register QTT are less than or equal to 5 bonds. Here, since the following is true, the program proceeds to step S11-3. In this step, 2 is set in the processing number register PCNT, which is a processing number processing section. If the number of bonds is less than 2 in step 311, the program reaches step S11-2, the processing count register PCNT is set to 1, and
If no in step 11-2, the program goes to step S11.
-4 step is reached, and 3 is set in the processing count register PCNT.

In the continuation<811-5 step, the defrosting time counter DT is
divided by the contents of the processing count register PCNT plus 1 (in this case 2+1 is set in the interval register FT).The program then cycles through steps 312-315.

At step 812, the remaining defrosting time is displayed on the display (5) based on the contents of the defrosting time counter DT. In step S13, the output of the heating signal HEAT is controlled and thawing cooking is started at the desired microwave output. In this case, the microwave output is automatically controlled to 600W at 100%. That is, the heating signal HEAT is continuously output. In step S14, the second counter SEC in the processor (7) starts counting seconds, and in step S15
In this step, it is possible to determine whether or not the second counter SEC has counted one second.

Then, when the 1 second count is done, the program returns to 31.
The cycle of steps 2 to S15 is exited at step 815.
Proceed to step 16. In this step, the seconds counter SEC
The counting operation of is stopped and its contents are cleared.

In the next step 317, the content of the defrosting time counter DT is subtracted by 1 second. In the following step 818, it is determined whether the contents of the counter DT have become 0 or not. Now not 0, the program then reaches step 319. In this step, the content of the first stage counter DTI is subtracted by one second, and in the next step 820, it is determined whether the content of the counter DT1 is greater than zero. Now the content of such counter DTI is greater than 0, and the program is S21
Reaching the steps. In this step, the contents of the interruption interval counter PTa in the processor (7) are incremented by one, and in the following step S22, it is determined whether the contents of the counter PTa have reached the contents of the interruption interval register PT. .

Since the state has not yet been reached, the program returns to step 812, and thereafter cycles through steps 812 to 815, repeating the state through steps 816 to S22 every second (hereinafter referred to as the A state).

Therefore, as described above, the first stage counter DT1 and interruption interval register FT initially contain 3 minutes 45 seconds and 4 minutes 10 seconds, respectively.
If seconds are counted, the interrupt interval counter P
The content of the first stage counter DTI becomes O before the content of Ta reaches the content of the interruption interval register FT. When the content of the counter DTI becomes 0, the program exits the A state from step 320 and returns to step S20-1.
Reach step □. In this step, S
When the 13th step is reached, the microwave output is 50% and 30%.
Its output is set to 50% so that it becomes 0W. That is, when reaching the S13 stencil, the heating signal HEAT is controlled to be output for 10 seconds at a cycle of 20 seconds. The program then returns to step S12 through steps S21 and S22, and then cycles through steps 312 to S15, and every second passes steps S16 to S20, S20-1, S21,
The state through step S22 is repeated (hereinafter referred to as B state).

The output in this case is <300W as described above.

Thereafter, the contents of the interruption interval counter PTa reach the contents of the interruption interval register FT (at the time PL). Therefore, when it reaches such a point, the program returns to 32 of the above B state.
2 steps to 823 steps. In this step, the output control of the heating signal HEAT started in step 813 is stopped, and the thawing cooking is interrupted. next 82
In step 4, the buzzer signal BZ is output for a certain period of time to provide buzzer notification.

The program then cycles through steps 825-S27. At step S25, 'TURN' is displayed on the display <5), step 326 is the same as step S2, and at step 327 it can be determined from the key information at step S26 whether or not the start key has been operated.

Now, the cook should use the above buzzer notification, and also the above 'T U
The cook confirms on the RNu display that the food must be turned over to eliminate uneven thawing, and then opens the door (2) to turn over the food for the first time. After that, close the door (2) and operate the start key.
The program repeats the above steps S25 to S27 32 times.
It leaves the 7th step and reaches the 328th step. In this step, the contents of the interruption interval counter PTa are cleared.

The program then enters the above B state and thawing and cooking can be restarted, and when the contents of the interrupt interval counter PTa reach the contents of the interrupt interval register PT again (at time P2), the program starts from step 822 in the B state to 323 and S2.
After 4 steps (suspension of defrosting/cooking), steps S25 to S27 are cycled.

Then, the buzzer notification and rT U R Nu display are confirmed by the cook again, and the cook then performs the process of flipping the food for the second time when opening the door (2>). When closing 2) and operating the start key in the same manner, the program passes through step 828 and enters the old state B, where thawing and cooking are started three times.

Thereafter, when the contents of the interruption interval counter PTa reach the contents of the interruption interval lister PT-, the thawing time counter DT becomes 0 in such thawing cooking, and the program repeats step 318 similar to step S23 above. -1 step is reached and thawing cooking is completed. And the program is the above S
After going through step S2 and step S3, a state is reached in which key information for the next cooking can be input.

Although the above embodiment is for eliminating uneven defrosting, it goes without saying that it can also be applied to eliminating uneven cooking times.

Furthermore, in the above embodiment, there is only one weight chart stored in advance in the ROM area, and in all defrosting cooking, such charts are referred to to determine the defrosting time. There is.

In contrast, a specific optimum chart is provided for each type of food to be thawed, for example, meat and fish, and the keyboard (6)
In this case, for example, a meat thawing key and a fish thawing key are provided in place of the above thawing key, so that when thawing meat, the meat thawing key must be operated, and when it comes to referring to the chart, it is most suitable for thawing meat. specific charts can be referenced. The same goes for defrosting fish.

Then, thawing and cooking can be performed more preferably.

(G) Effects of the Invention According to the present invention, the control section that controls the driving of the heating energy generating means to execute cooking causes the number processing section to process the number of times based on the weight information of the food, and The system determines an appropriate time based on the above information, and also activates the notification means when the time to refuse cooking is reached, so the cook can be automatically notified of the time to perform the desired process, and the number of times the process is to be performed is automatically notified. It can be adjusted according to the weight of the food, and if desired processing is performed based on the above notification, occurrence of uneven thawing, etc. can be significantly suppressed.
