[0005]

SUMMARY OF THE INVENTION The present invention is provided with the following means for solving the above problems in order to surely solve the problems of the conventional high frequency heating apparatus and to effectively achieve the object. I have.

That is, the high-frequency heating device of the present invention comprises:
A fry menu selecting means, and heating control means for sequentially performing heating from range heating to heater heating on condition that the fry menu is selected by the fry menu selecting means and baking and cooking unfried food without using oil. It is configured.

Further, the high-frequency heating apparatus according to the present invention comprises a fry menu selecting means and a weight judging means for judging the weight of the unfried food on the turntable on condition that the fry menu is selected by the fry menu selecting means. Heating control parameter setting means for setting heating control parameters such as a range heating time, a heater heating duty, and a heater heating time according to the determination result of the weight determination means; and heating control set by the heating control parameter setting means. And heating control means for sequentially performing heating from range heating to heater heating based on the parameters and baking the unfried food without using oil.

[0008] More specifically, the weight determination means further includes a weight sensor, and the weight sensor directly detects and determines the weight of the unfried food on the turntable, or includes a temperature sensor. The weight of the non-fried food is detected and determined indirectly based on the difference in the internal temperature rise rate at the start of the heater heating calculated based on the output of the temperature sensor.

[0009]

As described above, in the high-frequency heating apparatus of the present invention, first, range heating is performed based on the fly menu selection means and predetermined heating control parameters on condition that the fly menu is selected by the fly menu selection means. Perform heating and heating the whole non-fried food evenly and much faster than the heater, and then perform heating for a relatively short time to bake and cook the surface of the non-fried food. And heating control means for performing heating and baking without using oil, respectively, and when a fly menu selection means such as a fly menu key is operated, for example, a range heating time, a heater heating duty, a heater heating time, etc. Heating control parameters are set, and range heating and heating are performed by the heating control means based on the heating control parameters. It is performed without using a proper warm suitable baking heating and oil each heating the surface of the central portion of the automatically non-fried foods running and motor heating in a predetermined pattern.

In the high frequency heating apparatus according to the present invention, the fly menu selecting means and the weight determining means for determining the weight of the unfried 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 a range heating time, a heater heating duty, and a heater heating time according to the determination result of the weight determination means; and heating control set by the heating control parameter setting means. First, range heating is performed based on the parameters to uniformly heat and heat the whole non-fried food much faster than the heater, and then heating the heater for a relatively short time is performed to perform the heating of the non-fried food. There is a heating control means that performs appropriate baking heating only on the surface without using oil. The weight of the unfried food is determined by the weight determination means when the fly menu selection means such as the fly menu key is operated, and the heating control parameter setting means determines the range heating time, heater heating duty, and heater according to the determined weight. Set heating control parameters such as heating time. The heating control means performs range heating and heater heating based on the same heating control parameters, and automatically heats the center portion of the non-fried food and heats the surface portion using oil, respectively. Done without.

In this case, when the weight determining means includes a weight sensor, the weight sensor directly detects and determines the weight of the non-fried food directly, and an appropriate range heating time, heater heating duty, Since the heating control is performed during the heater heating time, an optimum finished state can be realized without causing rupture of the unfried food due to overheating of the range or scorching due to overheating of the heater.

When the weight determining means includes a temperature sensor and determines the weight based on the difference in the rate of increase in the internal temperature at the start of the heater heating, the weight is indirectly determined. The weight of the fried food is accurately detected and determined,
Precise range heating time corresponding to the determination value, heater heating duty, heating control in the heater heating time is performed, without causing such as rupture of unfried food due to range overheating or scorching due to heater overheating, Similarly, an optimal finished state can be realized.

An internal temperature sensor is provided as required, and the initial heating and the continuous heating are distinguished based on the internal temperature detected by the internal temperature sensor. 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 accuracy is further improved.

Further, the switching from the range heating to the heater heating in each of the above cases is performed by detecting the completion of the range heating to the desired level based on the detection value of the humidity sensor, and then switching to the heater heating. Is also good. This makes it possible to set a substantially appropriate range heating time without a weight sensor.

[0015] The heater heating is turned off by using, for example, a temperature sensor.
It may be turned off only when it is detected within a predetermined time that a constant temperature of about 80 ° C. has been reached. Alternatively, the range heating and the heater heating may be set and set in advance.

[0016]

As a result, according to the high-frequency heating apparatus of the present invention, unlike the conventional apparatus, it is possible to extremely quickly and uniformly heat the whole non-fried food including the central part and bake an appropriate surface part, unlike the conventional one. This can be realized without using oil, the heating efficiency is improved, and the finished state of the fried food itself is the same as that obtained by fried food.
Also, because it does not use oil, there is no need to wait for the oil temperature to rise like a fryer, and it is easy to clean up,
Cooking time is short.
