Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a high frequency heating device using a microcomputer.

Conventional high-frequency heating equipment controlled by a microcomputer (hereinafter referred to as microcomputer) has keys for selecting multiple heating output methods and several numeric keys for arbitrarily setting the cooking time.
It is common for the user to set the desired cooking using the .

Problems to be Solved by the Invention As mentioned above, in the conventional high-frequency heating apparatus, even if cooking is frequently performed, settings must be made once at a time, which requires time and effort to operate.

The present invention solves these conventional problems and provides a high-frequency heating device that has a simple configuration and does not require troublesome key operations.

Means to Solve the Problems The high-frequency heating device of the present invention has a plurality of cooking times that are used most often for each cooking power, a storage means for storing the cooking times, and a cooking output selection key (hereinafter referred to as cooking power). (referred to as key)
When is pressed, there is an addressing means for fetching the cooking time from the storage means according to the type or number of keys pressed. Furthermore, in preparation for changing the cooking time prepared in advance, the cooking time changing key is provided, and cooking time changing means is provided for writing a new cooking time set into the storage means.

Function According to the present invention, the cooking time can be set simply by pressing the power key, so the operation is very simple. It is also possible to freely set the cooking output and time.
It can be flexibly adapted to your preferences and frequency of use.

Example Hereinafter, an explanation will be given based on one embodiment of the present invention.

FIG. 2 is a perspective view of the main body of the high-frequency heating device of the present invention.

A door 202, a display tube 8, and a key operation section 204 are provided on the front surface of the main body 201.

203 is a heating chamber in which food is placed.

FIG. 1 shows a configuration diagram of an embodiment. The microcomputer 1
Address setting means 4 in 2 outputs a signal for accessing storage means 6 depending on the type and number of times the key is pressed. The storage means 6 is provided with a plurality of cooking time cents for each power in advance, and according to the signal from the address setting means 4,
The contents of the storage means 6 are sent to the cooking setting means 6.

Also, at this time, the cooking time change key 2 in the key operation section 204
If there is an output signal from the cooking setting means 6, the setting of the cooking time is changed in the cooking time changing means 9 together with the contents of the cooking setting means 6, and the result is sent to the cooking setting means 6. Next, depending on the output from the cooking start instruction key 3 (hereinafter referred to as the start key) that instructs the start of cooking and the output from the cooking setting means 6, the control means 7 connects and connects the relay that is the load control means 10. The heating means 11, ie, the magnetron, oscillates and cooking starts.

The control means 7 also controls the display means 8 at the same time, so that appropriate information such as setting time and output is displayed.

Further, the cooking information changed by the cooking time changing means 9 can be stored in the storage means 6 using these signals and the signals from the cooking time changing means 9 by operating the power key 1 in a specific procedure. Once the information has been rewritten, you can make cooking settings with the new content next time.

FIG. 3 is an enlarged front view of the display tube which is the display means 8 of this embodiment and the key operation section 204. The display tube has numeric display sections 301 to 306 that display cooking time, etc., and 306 to 3 that display the cooking set selected by power key 1.
There are ten output displays. In addition, the key operation section includes three power keys 1, 311 to 313, for selecting different outputs and cooking times, two time change keys 314, 315 for increasing/decreasing the set time, and a cooking start instruction means 3. A start key and a cancel key 316 for canceling cooking are provided.

FIG. 4 shows the operation of the power key 1 and the display shown on the display tube 8 in this embodiment. Two frequently used cooking times are pre-assigned to each power.
ing. For example, Mad Power comes in 10-minute and 25-minute cooking times. Then, when the power key 312 is pressed once, a display representing 10 minutes appears on the numerical display sections 301 to 306. Since the cooking output is Mad, 307 is attached, and 309 indicating that it is the first cooking is attached (FIG. 4 (IL)). When the key 312 is further pressed, the next setting is 26 minutes, and the display section 310 indicating the second cooking is also displayed instead of 309 (see Fig. 3).
b)). In this state, it is possible to start cooking by pressing the start key 3. If 25 minutes is too short or too long, you can change it using the cooking time change key 2. For example, to shorten the cooking time, press the key 314 to shorten the cooking time by 1 minute (Fig. 4 (0), (+11
). Similarly, two cooking times can be selected and changed using the other two keys. Here, if 26
If you want to always set the cooking time to 23 minutes instead of the cooking time of minutes, do the following to memorize 23 minutes. Figure 4 (In the state shown in (1), press the power key 3 before pressing the start key 3.
When you press 12 once, the display section 309 lights up (see Fig. 4(e)
)). If you want to be number 1 in Mad Power, then'!
If you want the second person to memorize the power key 312
When you press again, the display section 310 lights up (Fig. 4 (f)
)). If the start key 3 is pressed here, a new cooking time is entered into 1 or 2, and cooking is also started at the same time.

Next, the program of the microcomputer 12 for realizing the operation explained in FIG. 4 will be explained using a flowchart. First, in step 61, key input is read and its type is determined. Next, in step 52, it is determined whether the key is the power key or not, and if Yes, the process proceeds to step 57. If NO, it is determined in step 53 whether it is a time change key, and then the process proceeds to step 64. If it is a start key, the process proceeds to 5f. In step 67, a flag is checked to see if the cooking time has already been changed. When the power key is pressed for the first time, the flag is not 1, so in step 58 the cooking setting flag is set to 1, and in step 69 addressm is calculated in order to access the memory in which the cooking time is stored. In step 6a, the calculated address is set in the memory MO, and then in step 6b, the contents of the memory corresponding to the address are transferred to the memory MW. In this way, a cooking setting means for accessing a stored cooking time can be achieved depending on the type of power key and the number of times the power key is pressed. Further, in step 64, a flag indicating that cooking is being set is determined, and the process proceeds to step 65. Here is the memo I that corresponds to the cooking time.
The program increments or decrements JMW in accordance with the pressed key, sets the flag indicating that the cooking time has been changed to 1 in step 56, and exits. Step 6c is a process for re-memorizing the changed cooking, and each time the power key is pressed, the value of memory M is incremented, and in step 5d, the value of memory M is
Transfer the value of the program to the memory Mo. At step 60, the memory change flag is set to 1. If the pressed key is the start key, the process advances to 6f, where it is determined whether cooking settings are currently in progress, and the memory change flag is checked at 5g. If 6C
If the subsequent processing has been performed, the flag will naturally be 1, so it will be 6h.
Set the contents of memory MO to register H at 6.
At j, transfer the contents of memory MY (time after change) to the memory corresponding to the address indicated by register R, and then at 6
Proceed to h, set the cooking flag to 1, and exit. Also,
If the memory has not been changed in step 6g, there is no need to change the memory contents, and the process directly advances to step 6. In this way, programs for setting cooking, changing cooking time, and re-outputting to the storage means can be realized (see FIG. 5(a)). Next, the program of the control means is shown. First, in step 51, the cooking setting flag is determined,
If it is 1, the contents of the memo IJMW are displayed and output in step 5r so that the setting is displayed. If it is not 1, it is determined in step 51 whether or not cooking is in progress, and if cooking is in progress, a memo containing the cooking time IJMW is entered in step 6m.
Decrement the contents of. Next, in step 5n, the output signal to IJ l/-, which is the load control means, is intermittent, and the process proceeds to step 5r to display the cooking status. The above is the program of the control means.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the following effects can be obtained.

(1) When the power key is pressed, the cooking times are displayed in order of frequency of use, and there is no need to enter the cooking time, so the operation is simple and hassle-free.

Import) It is possible to memorize the time according to the user's request.

(3) Since it can be implemented with a small number of keys, it can be used even if the microcomputer used has a small number of ports, and costs can be reduced.
