Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven and its heating container.

[0002]

2. Description of the Related Art In recent years, microwave ovens have not been widely used, and their heating applications have been expanded, and a large number of specialized containers have been provided according to the purpose of heating and cooking.

[0003]

However, the containers provided hitherto have not been suitable for cooking cooked or steamed foods for a long time.

That is, in the case of performing radio wave heating in a conventional container, it is necessary to heat for a long time in order to prevent the temperature of cooked food from lowering due to heat radiation even after boiling in order to sufficiently simmer or soak the taste. Therefore, when the above-mentioned cooking is performed, the cooking device is occupied for the cooking and other cooking cannot be performed, and it is necessary to continuously perform radio wave heating in order to maintain a constant temperature. There were challenges.

The present invention solves the above problems and provides a heating container for a microwave oven capable of efficiently cooking cooked and steamed foods with a simple structure in a short time, and using the container. It is intended to provide a microwave oven capable of heating and cooking.

[0006]

The present invention has the structure described below in order to achieve the above object.

That is, it is composed of a pan body having a double wall structure having a hollow space in the bottom and side walls and a lid for closing the pan body, and at least one of the pan body and the lid is radio wave permeable. The container was made of the above materials.

The hollow space of the container has a vacuum structure. Further, the microwave oven of the present invention includes a heating chamber for heating an object to be heated, a magnetron for supplying an electric wave to the heating chamber, a power source for driving the magnetron, and a hollow space at the bottom and side walls placed in the heating chamber. Of a double-walled pan body having a void and a lid closing the pan body, and at least one of the pan body and the lid heats an object to be heated made of a radio wave transmitting material. For this purpose, a heating container to be housed, a sensor for detecting the boiling state of the heating container, and a controller for controlling the power supply by the signal of the sensor are used.

[0009]

According to the present invention, the cooked food once heated does not decrease in temperature for a long time because the heating container is insulated. In addition, since the heating container is housed in the microwave oven and a sensor for detecting the boiling state of the heating container is provided, it is possible to control the cooking quality by controlling the power supply by the signal of this sensor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows a state in which the heating container of the present invention is placed in the heating chamber of a microwave oven. The radio wave generated from the magnetron 1 is supplied to the heating chamber 3 via the radio wave opening 2. A heating container composed of a pan body 5 and a lid 6 is placed on the tabletop 4, and food 7 is stored in the container. The pan body 5 has a double-walled 9 structure having a cavity 8 in both the side wall and the bottom.

The lid cross section 10 of the pan body 5 is made of a plastic that is radio wave permeable and has a better heat insulating property than a metal plate or the like. The microwave oven is equipped with a humidity sensor 11 for detecting the boiling of food, and a controller 12
Is configured to control the power supply 13 for the magnetron.

The operation of the above configuration will be described. When the heating container having the above-mentioned configuration is subjected to radio wave heating in the heating chamber 3 of the microwave oven, the moisture contained in the food 7 is dielectrically heated by the radio wave transmitted through the lid 6 and the pan body 5 made of a radio wave permeable material to raise the temperature. To generate water vapor. The generated water vapor partially condenses inside the lid 6, collects as water droplets around the joint between the lid 6 and the pan body 5, and acts as a kind of airtight seal body.

As a result, in the heating container containing the food 7,
Since the amount of heat conduction to the external space can be reduced, an extremely uniform heating space can be formed. Further, the weight of the lid 3 can realize a high-temperature steam space in an overheated state, and the food can be sufficiently heated.

Cooking is completed by stopping the radio wave heating after heating and boiling and leaving it for a certain period of time.

By cooking in this manner, the following effects can be realized. (1) Does not boil over. (2) Do not miss the taste and scent. (3) Resource saving is realized because it is heated only for a short time. Further, according to the present invention, since the radio wave heating is used, the heating container does not need a heat conducting portion for heating, so that the food can be eaten at a high temperature food that has a high heat retaining effect and is forever. In addition, in order to perform radio wave heating in a conventional normal container, it requires a long cooking time after boiling to sufficiently simmer or to soak the taste, but if the heating container of the present invention is used, it takes a short time until boiling. After heating for a period of time, the heating container is taken out of the heating chamber 3 and is sufficiently insulated so that cooking can proceed without lowering the temperature. It can also be heated, and it is expected that the microwave oven can be used effectively and frequently. If the void 8 is degassed and brought into a vacuum state, the heat retaining effect can be further improved.

In the above embodiment, the pan body 5 is placed at the bottom and the lid 6 is placed at the top, but a configuration in which the vertical relationship is reversed is also possible. Further, in the embodiment, the pan body 5
Although both the lid 6 and the lid 6 are made of radio wave permeable plastic, either one may be made of a metallic double wall structure. Further, the present invention also includes the contents that the lid 6 has a double wall structure to enhance the heat insulation effect and that the pan body 5 is made of an optically transparent resin material so that the cooking process can be easily confirmed. Sensor 11 for boiling detection
Is not limited to the humidity sensor, but may be another detection means such as a weight sensor.

[0017]

As described above, according to the heating container of the present invention and the microwave oven using the same, the following effects can be obtained. (1) Since the heating container of the present invention uses the pan body which is heat-insulated by the double-walled structure having not only the side wall but also the bottom portion with the void portion, it has excellent heat insulating performance, and even if the cooked food is left to stand for a long time after being heated. There is almost no decrease in temperature. Therefore,
It can be cooked, such as steamed or stewed cooked foods, in which the temperature must be maintained after heating, or can be cooked by taking it out of the cooking device after heating. That is, since heating for a short time is sufficient, energy can be saved. Moreover, the utilization efficiency of the cooking device can be improved. (2) The airtight state between the main body of the pan and the lid that closes the pan is improved, so that the taste and aroma do not escape. (3) In the configuration of (1), there is little repetition of heating and boiling, heat radiation, and heating and boiling. (4) Since the microwave oven containing the heating container of the present invention is provided with a sensor for detecting the boiling state, the signal of this sensor can be used to detect the completion of cooking and the controller can easily control the heating source. it can.
