Abstract

PURPOSE:To achieve cookings in a constant finish and in the best finish according to the preference of a user by correcting a cooking data memorized with workmanship information inputted by the user at the end of a cooking. CONSTITUTION:A CPU3 controls a high frequency output or a heater output according to outputs of various sensors 1 and a cooking data from an RAM6. When a user opens a door of a heating chamber after the end of a series of automatic cooking, the CPU3 demands the user to input workmanship information using a display for a control panel. On the other hand, the user takes out a cooked food from the heating chamber to judge the workmanship of the foods and then, inputs the workmanship information with a workmanship input unit 7. The CPU3 corrects (rewrites) the cooking data in the RAM6 according to the workmanship information inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cooking appliance that automatically cooks food according to the output of a sensor that detects the state of food to be cooked and cooking data.

[Technical background of the invention and its problems]

Conventionally, this type of cooking appliance, such as a microwave oven, has been equipped with a control circuit as shown in FIG. 1st
In the figure, 1 is various sensors (such as an infrared sensor for temperature detection), f4. tJ-ta is memorized. 3 is a CPU (central processing control value ri\), which performs daytime output control, heating and output control, etc. according to the outputs of various sensors l and cooking data read from ROMz'f:1°j
It is now. Reference numeral 4 denotes a control block, which is composed of a frequency generator such as a magnetron and an electric heater for heating the oven, and is adapted to respond to commands from the CPU 3.

That is, as shown in Figure 2, when automatic cooking is first selected and a cooking start operation is performed, cooking using high frequency waves or cooking using heat generated by electricity/heater is started. At this time, the state of the food to be cooked is detected by various sensors l. Thus, the CPU 3 performs high frequency output control or heater output control according to the outputs of the various sensors 1 and the cooking data read from the ROM 2.

By the way, in such a microwave oven, cooking data'
is fixed, and the characteristics of the sensor and other parts vary due to changes over time, making it difficult to always cook with a constant finish. Furthermore, it has been difficult to obtain a finish that meets the user's preference.

To deal with this, as shown in Fig. 3, the high frequency output or the heater output can be switched between strong and weak by operating the strength changeover switch 5f connected to the CPU 3, thereby adjusting the finish state. However, it was difficult to meet the detailed requirements regarding the finished state with this method alone. This invention was made in view of the above circumstances, and its purpose is to It is an excellent product that can always cook to a constant finish without being affected by variations in the characteristics of sensors or other parts, and can also cook to the best finish according to the user's preference. Our goal is to provide cooking utensils.

[Summary of the invention]

This invention is a cooking appliance that automatically cooks food according to the output of a sensor and cooking data, in which the stored cooking data is corrected based on doneness information input by the user at the end of cooking. .

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. However, the same parts as in Figure 1 are given the same symbols.
0 As shown in FIG. 4, the detailed explanation is omitted.
The cooking data in Mz is transferred to RAM 6 and can be stored there. This cooking data transfer is performed when the power is turned on. And RAM6 is CPU? The cooking data can be read from the RAM 6 to the C'PU 3, and the cooking data in the R A II/I 6 can be rewritten by the CPU 3. And C
A workmanship information input device 7 is connected to the PU3. This doneness information input device 7 is used by the user to input doneness information upon completion of cooking, and does not include a keyboard or the like.

Next, the operation of the above configuration will be explained with reference to FIG. .

%J: When the power switch is turned on, the cooking data in IROM z is transferred to RAM 6 and stored there. However, when you select automatic cooking and start cooking,
The state of the food to be cooked is detected by the type sensor l, and the cooking data in the RAM'6 is read out to the CPU3.

The CPU 3 performs high frequency output control or heater output control according to the outputs of the various sensors 1 and the cooking data from the RAM 6.

In this way, when the series of automatic cooking is completed and the user opens the door of the heating chamber, the CPU... requests the user to input performance information using the display on the operation panel. Meanwhile, the user takes out the food to be cooked from the heating chamber and determines the doneness of the food to be cooked. However, the user can check the performance information using the performance information input device 7. , 4, the CPU 3 executes R according to the input workmanship information.
Correct (rewrite) the cooking data in AM6.

Therefore, if you continue to perform similar automatic cooking with the power switch on, the cooking will be performed based on the corrected cooking data, which will result in variations due to changes in the characteristics of various sensors over time. Even in the afternoon, it is possible to cook with a certain finish that is the opposite of hunting. especially,
The best finish according to the user's preference can be achieved by reverse cooking. Here, FIG. 6 shows how the finished product improves as the number of cooking operations increases.

By the way, when the user inputs the finished product information, he or she may make a mistake. It has become.

Further, depending on the input performance information 4, the cooking data in the RAMG may become abnormal, and in this case, correction of the cooking data is stopped.

In the above embodiment, since the cooking take is corrected in RAM6, the power switch is set to -H.
If you turn it off, the improved cooking data will be lost. Therefore, R
If the AM6 is connected to the power source and the operating voltage is always stored in the RAM 15, the improved cooking data in the RAM 6 will not be lost, which is convenient.

However, if the power plug is unplugged from the outlet for transportation or the like, or if the power supply itself is cut off due to a power outage, the improved cooking data in the RAM 6 will eventually disappear. To deal with this, R.A.
A rewritable ROM, so-called programmable ROM (FROM) may be used instead of the M6, and then there is no need to provide a backup function as described above.

Further, in the embodiment described above, the request for inputting technical information to the user is notified using the display on the operation panel, but the request may be notified by voice using a voice synthesizer. In addition, by adding a weight sensor as a sensor and adding weight-related information to the cooking data, detailed cooking that fully satisfies the cook's preferences is possible.

In addition, the present invention is not limited to the above-mentioned embodiments, and various modified embodiments can be made without changing the gist of the invention. This is an excellent cooking device that can always cook with a constant finish without being affected by variations, and can also cook with the best finish according to the user's preference. Can be provided.
