Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to equipment such as microwave ovens and electric ovens, which are operated by setting the output and time, and after the operation is completed, are operated again with the same output and time.

Conventional configuration and its problems As an example of a microwave oven with a memory, a conventional microwave oven has a configuration in which the heating output and heating time are set in advance and the contents are stored repeatedly by pressing the memory key. It is.

According to this method, for example, if you want to repeatedly heat for 50 seconds at "high", you can use the heating output setting means to
"High" and 50 seconds using the heating time setting means, press the memory key to repeatedly store this content in the memory, and then press the recall key to heat with the memorized content to save the content. Call and then input the heating start oyster key to start heating.

However, in the middle of heating, you can open the door and check the condition of the object to be heated, and if it is satisfactory, end the heating, or add another 10 seconds to the preset 50 seconds and set it to 60 seconds for the best condition. Add up to.

In this case, the internally memorized heating time is 50 seconds, so in order to make the same heated object again in the same heated state, the stored heating time of 50 seconds must be changed to the actual heating time. There was the inconvenience of having to change the time to the best time, for example 60 seconds.

That is, in the conventional example, if one wants to repeat the same heating operation for the same food five times, for example, there is a problem in that the best heating time must be determined before heating and stored as the repetition details. Ta.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and calculates and integrates the heating output during execution and the execution time while performing the heating operation at the output, and then inputs the memory key or presses the stop key. By integrating the above-mentioned counts until a predetermined input is received, such as an input or the end of a pre-memorized time, the heating output and heating time that were performed just before are stored, and the above-mentioned memorization is performed by repeatedly inputting the operation key. The purpose of the present invention is to provide a cooker that starts heating again depending on the contents of the cooking device.

Structure of the Invention In order to achieve the above object, the cooking device of the present invention has a memory function (1), a heating output switching means, a heating output setting means, a heating time setting means, a heating start input key 1, a heating chamber door, and a heating chamber door. It is equipped with a switch that indicates opening/closing, a stop key that stops heating, a memory key that memorizes the contents of heating, and a repeat key that repeatedly executes the memorized contents, and a book that stores the heat output during heating operation. With,
Equipped with an internal calculation memory that counts and accumulates hydraulic operation time.
The actual heating output and time are memorized from the start of heating until the memory key is activated, and if the key is repeatedly input, the contents stored in the #l number are displayed and can be executed. During cooking, the heating output and
Even if the heating time is changed, all of these are automatically stored internally, so that the same repeated heating operation can be automatically repeated. Another advantage is that heating can be repeated for the heating output and time determined or found while making adjustments.

In other words, as shown in the disadvantages of the conventional example, when heating the same object five times in the same way, the heating power should be set as appropriate, for example, high, for the first time, and the heating time should be set as desired. For example, enter 50 seconds to start heating, open the door midway through to check how well the object is being heated, and if it is insufficient, reset the heating time to a longer time and restart heating. In this way, when you press the memory key at the best point, the heating output and total heating time up to that point are automatically memorized, so all you have to do is press the key repeatedly for the remaining 41 times. This has the effect that heating can be repeated using the optimal heating time and output that has just been performed, and the operator does not have to calculate the total amount of time added in between, which is convenient.

To remember the remaining time while setting the output or during actual operation,
It has a display memory, a numerical display area, an output display, etc., and includes a time vane counter to measure the time every second, and a flag called 5eel to indicate one second.

The functions of these configurations will be explained.

First, when the stop key 17 is pressed or the power is turned on, the display shows one zero. Here, first press the switch 11 of the operation section 2 to set the heating output as "High", then operate the number keys 7, 8, 9, and 10 to display "12 minutes 20 seconds" on the display section 3. . Next, close the heating chamber door and press the 16 start key to start heating, and the heating will start at a high output (600W).
12 minutes and 20 seconds (continuous oscillation), heating starts when the device attempts to open, and the displayed 12 minutes and 20 seconds counts down every second.

For example, if you open the door with 10 seconds left,
Since the switch 52 linked to the door is opened and this is input to 25, the heating operation is interrupted.

Check the condition of the heated object and if it is insufficiently heated,
Assuming that the heating time is 0 seconds, the heating time setting units 10 and 9 are operated to change the display to 30 seconds. Then, close the door and press the start key 16 again to start heating again, leaving 10
When the door was opened again at the second mark, the heating was at just the right level, so the memory key 14 was pressed to memorize the heating contents up until now. Next, when the key 15 is pressed repeatedly, the total heating time of the heating up to now, that is, (12 minutes')
20 seconds - 10 seconds) + (30 seconds - 10 seconds) = 12 minutes and 30 seconds is displayed, resulting in the display shown in FIG.

At this point, if the door is closed and the start key 16 is pressed again, the optimal heating that was just performed can be performed.

Therefore, if the operator changes the time midway, the Tota
A great effect is obtained in that there is no need to perform the above calculation of the heating time of 1 at all.

This is because control is performed according to the flowcharts shown in FIGS. 5(a), (1,), and (C).

In other words, the heating output and the heating time are stored while the reinforcement is actually being applied, and when the repeat key 15 is pressed, the heating time and the heating output are called up at that time. It is.

In the above example, it was explained that only one type of heating output is memorized, but this was done to simplify the explanation, and it is obvious that it would be more convenient to be able to memorize several types of heating output. .

In addition, in the explanation, it was explained that the heating time and heating power to be repeated are memorized by pressing the memory key 14, but this may also be stored by pressing the stop key 17, for example. An example is shown in FIG. 5(b).

In any case, the present example can be configured if the execution time during heating is counted and integrated depending on a certain predetermined input.

Effect of the invention According to the present invention, the following effects are obtained.

(1) It is convenient because the contents can be carried out again after heating is finished.

(2) Since there is no need to accurately determine the heating time prior to heating, the optimal time can be adjusted in various ways.

(3) Since the cumulative heating operation time is stored in the internal memory, it is automatically stored after heating is completed, so there is no need for troublesome repeated operations.
