An automatic heating control system that drives a heater to perform heating is adopted.

Recently, as one of the automatic cooking menus, foods such as croquette, pork cutlet, fried shrimp, and fried fish which are generally bread crumbs adhered to the surface (hereinafter, these are collectively referred to as fried foods) are output as heaters. A high-frequency heating device having a fly menu function of automatically heating is provided.

[0004]

According to the one having the automatic heating function of the fly menu, the clothes (rollers) on the surface can be finished by heating with the heater, and the heating state can be realized by warming the same as when frying. You can
For example, raw frozen fried foods can be finished without frying.

However, since the heating by the heater is radiant heating from the surface of the food, it is difficult for the heat to permeate into the inside of the food, and even if the heating is performed in consideration of the weight, the central portion It often happens that the temperature remains as warm as 50 ° C. Moreover, the heating time is generally long. Such a problem becomes more remarkable in the case of the frozen food because the temperature of the food itself is low.

On the other hand, if the heating output (output duty) of the heater is increased in order to solve the problem, the inside can be heated in a relatively short time, but the surface is burnt this time. .

The present invention has been made in view of such circumstances, and by combining the range heating prior to the heater heating, the surface finished state (baked) as well as the internal finished state (heated) can be obtained. An object of the present invention is to provide a high-quality high-frequency heating device with an automatic heating function of a fly menu that can be favorably performed.

[0008]

The present invention comprises the following problem solving means in order to surely solve the problems of the above-mentioned conventional high-frequency heating apparatus and effectively achieve the object. There is.

That is, the high frequency heating apparatus of the present invention is

More specifically, the weight determining means further includes a weight sensor, and the weight sensor directly detects and determines the weight of the fried food on the turntable, or includes a temperature sensor. It is configured to indirectly detect and determine the weight of the fried food based on the difference in the temperature rise rate in the refrigerator at the start of heating the heater, which is calculated based on the output of the sensor.

[0012]

As described above, in the high frequency heating apparatus of the present invention, the range heating is first performed on the basis of the fly menu selecting means and the predetermined heating control parameter provided that the fly menu is selected by the fly menu selecting means. Heating to heat the whole fried food evenly much faster than the heater, and then perform heater heating for a relatively short time to perform appropriate baking and heating only on the surface of the fried food. When the fly menu selection means such as the fly menu key is operated, heating control parameters such as range heating time, heater heating duty, and heater heating time are set, and the control means is used as a basis. In addition, the heating control means performs range heating and heater heating in a predetermined pattern to automatically fry foods. Baking heating suitable warm heating the surface of the central portion is carried out.

Further, in the high frequency heating apparatus of the present invention, the fly menu selecting means and the weight determining means for determining the weight of the fried food on the turntable on condition that the fly menu is selected by the fly menu selecting means. Heating control parameter setting means for setting heating control parameters such as range heating time, heater heating duty, heater heating time, etc. in accordance with the determination result of the weight determining means, and the heating control parameter set by the heating control parameter setting means Based on the above, a range heating is first performed to heat and heat the whole fried food evenly much faster than the heater, and then a heating for a relatively short time is performed to heat only the surface of the fried food. A heating control means for performing appropriate baking heating is provided, and a fly menu key or the like is provided. When the menu selection means is operated, the weight of the fried food is determined by the weight determination means, and heating control such as range heating time, heater heating duty and heater heating time is performed by the heating control parameter setting means according to the determined weight. Set the parameters. And
The heating control means performs range heating and heater heating on the basis of the heating control parameters to automatically perform appropriate heating of the center of the fried food, heating of the surface and baking of the surface.

In this case, when the weight determining means is provided with a weight sensor, the weight sensor directly detects and determines the weight of the fried food directly, and an appropriate range heating time, heater heating duty, and heater corresponding thereto are determined. Since the heating is controlled by the heating time, it is possible to realize the optimum finished state without causing the fried food to burst due to overheating of the range or the sticking due to overheating of the heater.

Further, when the weight judging means is provided with a temperature sensor and judges the weight based on the difference in the rate of increase of the temperature inside the chamber at the time of starting the heating of the heater, the weight is indirectly judged by the fly.

A configuration that reflects the setting of the heating control parameter is also adopted. By doing so, the set value of the heating amount becomes more accurate, and the finishing system is further improved.

Furthermore, in each of the above cases, the range heating is switched to the heater heating by detecting the completion of the range heating to a desired level based on the detection value of the humidity sensor, and then switching to the heater heating. Good. By doing so, it becomes possible to set the range heating time substantially appropriately without the weight sensor.

To turn off the heater heating, for example, a temperature sensor is used, and the temperature inside the refrigerator is set to 1 by the temperature sensor.
It may be turned off only when it is detected within a predetermined time that a constant temperature of around 80 ° C. is detected. Alternatively, the pre-heated range heating and the heater heating may be patterned and set.
