[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is provided so that a first metal cooking utensil is placed in a refrigerator with a second metal cooking utensil mounted thereon, and heater heating is performed following high-frequency heating. It relates to a heating cooking device to be executed.

[0002]

2. Description of the Related Art Conventionally, a microwave oven with a grill cooking function has been used to defrost and warm cooked frozen foods such as frozen hamburgers and frozen croquettes. In this case, as shown in FIG. 11, a metal oven dish 2 is placed on a metal rotating net 1 provided as an accessory of the microwave oven, and the cooked frozen food 3 is placed on the oven dish 2. It is arranged in a microwave oven in a state where it is placed. When the heater heating is performed by energizing the upper and lower heaters disposed on the upper surface and the lower surface in the oven storage, the frozen food 3 placed on the oven plate 2 becomes
The upper surface is directly heated by the upper heater, and the lower surface is heated by the oven plate heated by the upper heater and the lower heater, so that the whole food can be heated and finished smoothly.

However, in the above-mentioned cooking method, since the surface of the frozen food is heated, it takes a relatively long time to heat the whole frozen food, and the cooking time varies depending on the type of food. It was difficult to carry out automatic cooking by means of the method.

In order to realize automatic cooking, frozen foods are heated by high frequency heating.
According to such high-frequency heating, the whole frozen food can be uniformly heated, so that the cooking time can be shortened, and gas is generated from the food with the progress of the cooking, so that the amount of gas generated , Automatic cooking becomes possible. In this case, as shown in FIG. 12, high-frequency heating is performed with the glass dish 4 placed on the rotating net 1 of the accessory and the cooked frozen food stored in the glass container 5. . As a result, gas is generated from the frozen food with the progress of heating and cooking, so that heating and cooking can be performed based on the amount of gas generated.

[0005] However, the high frequency heating directly heats the moisture contained in the frozen food, so that when the frozen frozen food such as fries is heated by high frequency, it cannot be finished as quickly as the heater.

[0006] As a method of solving the above-mentioned problem, it has been considered to perform heater heating after high-frequency heating for a set time. That is, since gas is generated from the cooked frozen food by high-frequency heating, the capacity of the frozen food is determined based on the gas amount, and the heater heating is performed for a heating time according to the capacity. in this case,
As an accessory for performing the heating cooking, an oven dish 2 is placed on a rotating net 1 as shown in FIG. Thereby, the cooked frozen foods such as fries placed on the oven plate 2 can be finished by heating with the heater.

[0007]

However, in the case of the above-mentioned conventional configuration, since the metal oven dish 2 is directly mounted on the metal rotating net 1, when the high-frequency heating is performed, the oven dish 2 is placed on the metal oven dish 2. There is no problem if the capacity of the placed frozen food is a load enough to absorb the energy by high-frequency heating, but if the capacity of the food is small, for example, one or two croquettes, it is absorbed by the food. There is a problem that a spark is generated between the rotating net 1 and the oven dish 2 due to the surplus high frequency that was not present.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a combination of metal cooking utensils in a storage in a state where the cooking utensils are combined, and to heat a heater following high-frequency heating. Another object of the present invention is to provide a heating cooking device that can prevent sparks from being generated between metal cooking utensils.

[0009]

According to the present invention, a first metal cooking utensil is provided in a state where a second metal cooking utensil is placed in a refrigerator and placed on a first metal cooking utensil. In a heating cooking apparatus for performing heating, an insulating cooking utensil provided between the metal cooking utensils is provided.

[0010]

The second metal cooking utensil is placed on the first metal cooking utensil with the insulating cooking utensil interposed therebetween, and the object to be cooked is placed on the second metal cooking utensil. And store it in the refrigerator. Then, when heating and cooking are started, first, high-frequency heating is performed. At this time, since the cooking utensils made of insulating material are interposed between the metal cooking utensils, no spark is generated between the metal cooking utensils even when high-frequency irradiation is performed. Further, since the object to be cooked is heated by heating the heater, it can be finished quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. FIG. 2 is a perspective view of the microwave oven main body. In FIG. 2, the inside of an oven 12 provided in the main body 11 is closed by a door 13. A rotating shaft 14 protrudes from the bottom of the oven chamber 12 and is rotated by a motor, and a turntable (neither is shown) is mounted on the rotating shaft 14.

An upper heater 15 is provided behind the upper surface of the oven chamber 12, and a lower heater 16 is provided behind the bottom surface. The temperature sensor 1 is provided in the oven chamber 12.
7 and a gas sensor 1 in the exhaust passage.
8 are provided. A magnetron 19 and a cooling fan 20 are provided in the machine room (see FIG. 6).

An operation panel 2 is provided on the front of the main body 11.
1, various switches 24 including a display unit 22 and a convenience store 23 (see FIG. 1) are provided therein. The convenience store 23 is an operation key used when heating a prepared frozen food such as hamburger or croquette.

FIG. 6 is a schematic configuration diagram of an electric circuit of a microwave oven. In FIG. 6, the temperature sensor 17 outputs a temperature signal according to the internal temperature to the control device 25. Further, the gas sensor 18 outputs a gas detection signal corresponding to the gas amount to the control device 25.

The control device 25 executes high-frequency heating for driving the magnetron 19 based on the operation states of the various switches 24, and also performs heater heating for driving the upper heater 15 and the lower heater 16. At this time, the control device 25 outputs the cooking course or the heating condition set by the various switches 24 to the display unit 22 and executes the heating cooking based on the signals from the temperature sensor 17 and the gas sensor 18. It has become.

Here, when the convenience store 23 is operated, the control device 25 performs high-frequency heating for driving the magnetron 19 for a set time, and then executes the upper heater 15 based on the gas detection signal from the gas sensor 18. In addition, heater heating for energizing the lower heater 16 is executed for a predetermined time.

On the other hand, the microwave oven of this embodiment has a rotating net 26 as a first metal cooking utensil shown in FIG.
And an oven dish 2 as a second metal cooking utensil shown in FIG.
In addition to 7, a heat-resistant glass dish 28 as an insulating cooking utensil shown in FIG. 5 is provided.

The operation of heating the prepared frozen food by the convenience store 23 will now be described. FIG. 7 is a flowchart showing the operation of the control device 25, showing only the operation when the convenience store 23 is operated, and other operations are omitted for simplification of description.

First, as shown in FIG. 1, an oven dish 27 is placed on a rotating net 26 with a glass dish 28 interposed therebetween, and a cooked frozen food 29 is placed on the oven dish 27 in the oven cabinet. 12 is mounted on a turntable (not shown).

When the convenience store 23 is operated, the controller 25 drives the magnetron (step S1). Thereby, high frequency is radiated from the magnetron 19 to the inside of the oven chamber 12, so that the oven dish 27
, The temperature of the frozen food 29 placed thereon is increased by high-frequency heating. Then, since gas is generated from the frozen food 29, when the set time has elapsed (step S2), the controller 25 stops driving the magnetron (step S3) and inputs a gas detection signal from the gas sensor. (Step S4), the capacity of the frozen food 29 is determined to determine the heating time (step S5). At this time, when the capacity of the frozen food 29 is large, the amount of generated gas is large, so the control device 25 extends the heating time.

Subsequently, the controller 25 energizes the upper heater 15 and the lower heater 16 for the heating time determined as described above (step S6). Thus, the frozen food 29 placed on the oven dish 27 is directly heated by the upper heater 15 on the upper surface, and is heated by the oven dish 27 receiving heat from the upper heater 15 and the lower heater 16 while the upper surface thereof is heated. Therefore, the frozen food 29 is finished crisply when its surface is heated.

Then, when the control device 25 energizes the upper heater 15 and the lower heater 16 for the heating time obtained as described above (step S7), it stops the energization (step S8).

By the way, at the time of the above-described high-frequency heating, high-frequency waves are radiated from the magnetron 19 to the inside of the oven chamber 12, so that the rotating net 26 and the oven plate 27 housed in the oven chamber 12 are made of metal. Sparks may occur between them. However, according to the above configuration, the metal dish 26 is attached to the metal rotating net 26.
8, the oven dish 27 is placed on the rotating net 26. Unlike the conventional example in which the oven dish is directly placed on the rotating net, the rotating net 26 and the oven are Spark does not occur between the plate 27 and the plate 27.

In the case of the present embodiment, as shown in FIG. 8, high-frequency heating is performed prior to heating the heater, so that the upper heater 15 and the lower heater 16 are supplied to the upper heater 15 and the lower heater 16 based on the amount of gas emitted from the cooked frozen food. The energization time of the frozen food 2 is determined by heating the heater as described above.
The automatic cooking of the frozen food 29 can be appropriately executed while finishing the food 9 smoothly.

FIGS. 9 and 10 show the timing of cooking in the second embodiment of the present invention. The difference of the second embodiment from the first embodiment is that in the first embodiment, both the upper heater 15 and the lower heater 16 are energized at the time of heating the heater following the high-frequency heating. FIG.
As shown in FIG. 7, only the upper heater 15 is energized.

According to the second embodiment, the glass plate 28 interposed between the rotating net 26 and the oven plate 27 does not receive heat from the lower heater 16 and the heat from the upper heater 15 is Even if the cooking by the convenience store 23 is repeatedly performed, the situation where the temperature of the glass dish 28 becomes excessively high as shown in FIG. 10 can be prevented. Thereby, while exerting the same effect as in the first embodiment, it is possible to avoid the risk of inadvertently touching the glass plate 28 and getting a burn, and to store the frozen food in a container, or In the case where the frozen food is wrapped in a wrap and cooked, it is possible to prevent a problem that the container or the wrap is deformed.

[0027]

As is apparent from the above description, according to the heating cooking apparatus of the present invention, since the cooking utensils made of insulating material interposed between the metal cooking utensils are provided, the metal cooking utensils are combined. The heater is provided so as to be housed in a refrigerator in a state where the heater is heated following the high-frequency heating, and has an excellent effect that a spark can be prevented from being generated between metal cooking utensils.
