Later, the buzzer alert 15 generally alerts the user about "Pee, Pee, Pee" about three times before reaching the end 17.

[0003]

However, the above configuration has a problem in that when the end buzzer is heard, it is not possible to know when the end is completed. Especially for business use, it is used while performing other cooking work in a large space, so it is often heard, especially when freezing raw raw fish such as frozen sashimi fish, finish thawing Subsequent leaving had a serious problem that thawing proceeded more than necessary, making it unsuitable for sashimi and leading to the propagation of various bacteria in foods.

In order to solve the above problem, there is a method of making the end buzzer sound a continuous sound until the object to be heated is taken out. It is noisy for users because it is noisy.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to make it possible to reliably recognize the end notification after the completion of cooking.

[0006]

In order to achieve the above object, the high-frequency heating apparatus of the present invention periodically notifies the end of the cooking until the door is opened (the operation of equipment required to take out the food) after the completion of the cooking. When there is no door opening operation after the buzzer notification, the control device has a time counting means for counting a predetermined time, and repeats the buzzer notification again after the predetermined time elapses, and elapses after the completion of cooking. Time cow
And means for displaying on a display device.

If there is no door opening operation after the buzzer notification, the control device counts the number of buzzer notifications, the buzzer volume setting means increases the buzzer volume stepwise according to the number, and the same time as described above. Counting means.

[0008]

Further, the buzzer is replaced with a voice.

[0010]

According to the present invention, after cooking is completed,
The door opening operation required to take out the food is detected, and if the door is left closed, the cooking end notification buzzer is notified periodically, or the buzzer sound is raised in a stepwise manner, or the buzzer is notified. In addition, it is possible to display the elapsed time after the completion of cooking on a display device, or to notify the user with a different sense by using an audio notification instead of the above-described notification buzzer, thereby completing the cooking completely. Come.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a basic circuit diagram of a high-frequency heating apparatus according to an embodiment, and FIGS. 2 to 4 show an operation sequence of the embodiment. In FIG. 1, 1 is a high-frequency oscillator, and 2 is its control device. A cooking mode, a cooking time, and the like set by the input device 3 including a keyboard or the like for setting a cooking mode and a cooking time are displayed on the display device 4 such as a fluorescent display tube, and a start key provided on the input device 3 The relay 6 is turned on by the operation, and the high-frequency oscillator 1 is operated. When the door is open during operation, the door switch 7 that operates in conjunction with the opening and closing of the door is turned off, and the operation of the high-frequency oscillator 1 is stopped. , Door switch 7 and door signal switch 8
Is also turned off, and the relay 6 is also turned off to stop the operation.

With the high-frequency heating device having such a circuit configuration,
An embodiment according to the present invention will be described with reference to FIG. Set 9 with the input device 3 and accept start 11 with the door closed 10
After a lapse of a predetermined time, the cooking ends 12 and a buzzer alert 13 is issued,
After the buzzer notification 13, the controller 2 determines whether the door has been opened to take out the object to be heated based on the operation state of the door signal switch 8. If YES, the process is ended 15; The time 18 is counted and the buzzer is notified again after a predetermined time has passed.
The buzzer is periodically notified by repeating steps 13, 14, and 18 until the door is opened.

In the above configuration, the buzzer notification is repeated periodically until the door opening operation for taking out the food is performed. It has the effect of noticing home,
At least the danger of being left for a long time after completion is extremely small.

Next, another embodiment of the present invention will be described with reference to FIG. 3 is different from the embodiment in that the rear door is opened after the buzzer notification 13, and when NO, the controller 2 counts the number of buzzer notifications 19 when NO, and raises the buzzer volume stepwise according to the number of notifications. Has a buzzer volume setting 20 for counting, and then counts a predetermined time 18 as in the above-described embodiment. According to this configuration, the buzzer notification is periodically repeated after the completion of cooking,
Since the buzzer volume is gradually increased, it is possible to thoroughly confirm that the user has finished cooking more effectively than in the embodiment.
This has the effect.

Another embodiment of the present invention will be described with reference to FIG. In FIG. 4, the point different from the above embodiment is that the buzzer notification 13 and the door opening NO 14
The point that the buzzer notification is periodically repeated is the same, but the elapsed time after the completion is counted together with the buzzer notification 13 from the cooking end 12, and the elapsed time is displayed on the display device 4. Up is finished 22
The elapsed time until the object to be heated is taken out is displayed as it is. The time display is erased 24 by a cancel key 23 provided on the input device 3. According to this configuration, the end buzzer is notified periodically as described above, but when it happens to be absent in the cooking chamber due to another task, the elapsed time after the end is known, so that the thawing progress state of the heated object is determined. There is an effect that it can be used for judgment.

The above-mentioned elapsed time display is canceled.
Needless to say, it can be automatically deleted after a predetermined time elapses after the completion of cooking without being deleted.

In the embodiment of FIG. 4, the buzzer is notified periodically by the buzzer notification 13, the door opening 14, and the time count 18, but the buzzer sound volume in the embodiment of FIG. 3 is increased stepwise. It may be combined with the method.

Further, the buzzer 5 in FIG. 1 is replaced by a speaker, and the buzzer notification 13 in FIGS. 2, 3 and 4 is used as a voice notification. Please give it out. "Has the effect of enhancing the product image as well as the effect of being able to appeal to humans more effectively than the mechanical buzzer sound.

[0020]

As described above, according to the high-frequency heating device of the present invention, the following effects can be obtained.

(1) After the cooking is completed, a buzzer for notifying the end of the cooking is periodically notified until the door is opened. Therefore, even if the user hears another cooking operation, the buzzer can be finished in a relatively short time. It has the effect of noticing, and it solves the problem of becoming unsanitary, as in the past, especially after the thawing of the organism, listening for a long time and notifying the food or leaving it in the breeding state of germs This has the very important effect of being performed.

(2) Further, by notifying the end buzzer periodically and increasing the buzzer volume step by step, the user can more thoroughly finish cooking, so that the above effect can be further enhanced.

(3) The end buzzer is periodically notified,
In addition, by gradually increasing the buzzer volume and displaying the elapsed time left after the end on the display device, if the user happens to be absent in the cooking room for another business, it becomes slow to take out the food, Since the elapsed time after the completion is known, there is an effect that the thawing progress state of the cooked food can be achieved.

(4) Further, by using voice notification instead of buzzer notification, there is an effect that the product can be appealed more gently and effectively to humans than a mechanical buzzer sound, and also the product image can be enhanced.

As described above, all of the above effects can be achieved by the program of the microcomputer in the control device, and can provide convenience to the user at very low cost without increasing the cost. It is.
