DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave heating apparatus for cooking food stored in a cooking chamber with a microwave generator.

[0002]

2. Description of the Related Art Conventionally, this type of microwave heating apparatus has
The food stored in the cooking chamber was cooked with a microwave generator.

[0003]

However, in the above-described structure, the food is simply cooked by heating with microwaves, and no other action such as corrosion inhibition can be added to the food.

Accordingly, it is a first object of the present invention to provide a food with an effect of suppressing corrosion as an effect other than the heating and cooking.

A second object of the present invention is to provide an operation control device which selectively uses only the heating cooking operation and the combination of the heating cooking operation and the corrosion inhibiting operation depending on the type of food.

[0006]

In order to achieve the first object, a microwave heating apparatus according to the present invention has a first electrode provided on a certain surface in a cooking chamber, and the first electrode is provided on the surface. A second electrode is provided on a surface opposite to the surface provided, and an electric field power supply for applying an electric field to the first electrode and the second electrode is provided.

[0007] To achieve the second object, the present invention is the isolated operation of the microwave generating device, have either the combined operation of the microwave generator and electric power supply provided with operation control device capable of selecting switching Things.

[0008]

In the microwave heating apparatus according to the present invention, an electric field is applied between the first electrode and the second electrode by the electric field power supply device. The food becomes harder to rot and lasts longer.

Further, the operation control device is selectively switched.
Thus, both the functions of heating and corrosion inhibition, the heating function alone, and the type of food can be used properly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, reference numeral 1 denotes a cooking chamber, and 2 denotes a microwave generator, which is provided to generate microwaves in the cooking chamber 1. Reference numeral 3 denotes a first electrode provided on the upper surface of the cooking chamber 1, and reference numeral 4 denotes a second electrode provided on the lower surface of the cooking chamber 1. Reference numeral 5 denotes an insulating member that insulates the cooking chamber 1 from the first electrode 3 and the second electrode 4. Reference numeral 6 denotes an electric field power supply for applying an electric field to the first electrode 3 and the second electrode 4. An operation control device 7 controls the operation of the microwave generator 2 and the electric field power supply 6.

In the above configuration, when the operation control device 7 operates the microwave generator 2, the food can be heated as in the conventional case. On the other hand, when the operation control device 7 causes the electric field power supply device 6 to operate, an electric field is applied between the first electrode 3 and the second electrode 4, so that an electric field is applied to the food placed therebetween, and the electric field is applied. This has the effect of making the food less likely to perish and lasting longer. FIG. 2 is a comparison diagram of a melon to which an electric field is applied and a melon to which no electric field is applied after 30 days. 8 is a melon to which no electric field is applied. Reference numeral 9 denotes a melon to which an electric field has been applied.
mm, the lower end was placed in contact with the second electrode 4, and an electric field was applied at an alternating current of 15 KV for 5 minutes. The melon 8 to which the electric field is not applied has its upper part depressed and mold is generated on the entire surface. However, the melon 9 to which the electric field is applied has a normal appearance, does not generate mold, and does not change. In this way, it can be clearly seen that the cooked food is less likely to rot due to the action of the electric field, and that it will last longer.

[0013] Next described selection switching operation in accordance with the type of the food by the operation control device 7. When the rice or the like is switched by the operation control device 7 and operated by both the heating action by the microwave generator 2 and the corrosion suppression action by the electric field power supply 6, warm rice can be obtained and the remaining food can be stored even if it occurs. . In the case of a food that only requires heating, the operation control device 7 is switched, and the operation may be performed only by the heating action of the microwave generation device 2.
In this way, the selection switching operation can be performed according to the type of the food.

[0014]

As described above, according to the present invention, not only the cooking object is heated and cooked by microwaves but also the electric field is applied between the first electrode and the second electrode. When an electric field is applied to the food, the effect of the electric field is that the cooked food is less likely to be spoiled and has a longer shelf life.

[0015] In addition, if the operation control device heats the cooking according to the type of the food, but the remaining food is left, the operation is performed by both the heating cooking action and the corrosion inhibiting action. It is possible to perform a selective switching operation in which the heating operation and the corrosion inhibiting operation are selectively used, such as the operation of only the operation.
