JPH1085130A - Cooking vessel for microwave oven - Google Patents

Abstract

PROBLEM TO BE SOLVED: To cook by a microwave oven in the case of cooking which necessitates a large amount of water by forming a microwave absorbing heat generator layer across a necessary width at the external surface of a vessel main body freely transmitting microwaves. SOLUTION: The vessel consists of a vessel main body 1 in the state of a deep bottom freely transmitting microwaves and an external cap 6 reflecting microwaves, and a microwave absorbing heat generating layer 4 is formed across the necessary width on the external surface of the main body 1. At the time of putting the vessel in the microwave oven and originating microwaves, the cap 6 reflects microwaves to prevent the excessive irradiation of microwaves from an upper surface, the layer 4 is made to generate heat, and a proper quantity of microwaves is allowed to irradiate the inside of the main body 1 through a non-microwave absorbing heat generating part 5. Then, while the evaporation of moisture at an early stage is properly suppressed, a matter to be cooked is properly heated and cooked by the heating operation of the layer 4 and a proper amount of microwave irradiation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking container for a microwave oven which is particularly suitable for cooking and steaming an object to be cooked.

[0002]

2. Description of the Related Art A microwave oven, which is a high-frequency heating device, guides microwaves radiated from a magnetron into an oven and irradiates the objects to be cooked with the microwaves. Is cooked by heating. Such a microwave oven has very excellent characteristics such as a high heating speed, no waste due to heating only the object to be cooked, little loss of nutritional value, high sterilizing effect, simple operation, and the like. Which are generally and widely used as very convenient cooking utensils.

[0003] By the way, such a microwave oven is not limited to a cooking method in which it is cooked with a small amount of water,
In the case of cooking methods such as boiling and steaming that require a large amount of water, a sufficient cooking effect cannot be exhibited. This is because, when microwaves are directly applied to the object to be cooked, the water in the object to be cooked is preferentially heated. It seems to cause.

The present invention solves such a conventional problem,
An object of the present invention is to provide a cooking container for a microwave oven that can reliably cook with a microwave oven even in the case of boiling and the like requiring a large amount of water.

[0005]

That is, the present invention comprises a deep-bottomed container main body through which microwaves can be transmitted, and a lid for reflecting microwaves. A cooking vessel for a microwave oven, wherein a microwave absorption heating element layer is formed over a required width.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The container body according to the present invention is formed in a relatively deep bottom which is convenient for cooking and the like, and is capable of transmitting microwaves and effectively exhibiting a far-infrared effect. -It is formed of a known ceramic material such as porcelain. The inner and outer surfaces of the container body are preferably glazed to prevent water absorption and uneven heating due to water absorption, and to facilitate removal of scorch and the like. The shape of the container body may be a known shape such as a round shape or an elliptical shape.

The microwave absorbing and heating element layer is formed so as to cover the outer surface of the container body in a range of 60 to 100%, and preferably, a non-microwave absorbing and heating element having a required space is provided on the bottom and side surfaces of the container body. It is preferable to form a part to transmit an appropriate amount of microwaves and irradiate the object to be cooked to assist heating.
As a main component of the microwave absorbing and heating element layer, a known microwave absorbing and heating material such as ferrite, silicon carbide, and barium titanate is used. The microwave-absorbing heating element layer is prepared by dispersing a powdered microwave-absorbing heating material in an aqueous or oily solvent to prepare a slurry or paste, and then spraying the slurry.
It may be formed by attaching to the outer surface of the container body by a known method such as spraying, dipping, or screen printing, followed by heat treatment and baking. Further, glass, ceramics, heat-resistant resin or the like may be coated as a protective film on the outer surface of the microwave absorbing and heating element layer.

Further, the lid may be made of a metal such as iron, aluminum, stainless steel, copper, or an alloy, or a plastic,
It is formed of a material obtained by laminating a metal plate or a metal foil on a microwave transmitting material such as glass or ceramics so as to reflect microwaves. Such a lid may be configured as a single lid, or may be configured as a double lid structure of an outer lid and an inner lid. Should be configured to reflect light. Further, the lid may be configured to have a large weight or to be locked to the container body in order to prevent rattling or spillage caused by boiling of the content during heating and cooking.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a deep-bottom ceramic round container main body through which microwaves can be transmitted, 2 is a flange portion integrally formed outwardly on the upper end edge of the container main body 1, and 3 is an outer peripheral edge of the flange portion 2 And a pair of locking notches formed opposite to each other. Reference numeral 4 denotes a microwave absorbing and heating element layer formed on the outer surface and the outer bottom surface of the container body 1, respectively, and reference numeral 5 denotes a non-microwave absorbing and heating unit formed annularly on the upper end and the outer bottom surface of the container body 1. Reference numeral 6 denotes an outer lid for reflecting microwaves which can be fitted to the container body 1, reference numeral 7 denotes a required number of air holes formed in the outer lid 6, and reference numeral 8 denotes a notch 3 of the container main body 1. It is a locking piece protruding from the outer peripheral edge of the outer lid 6 as much as possible. Reference numeral 9 denotes an inner lid which can be freely attached to the container main body 1. The inner lid 9 is a pair of circular inner lid members 11a having air holes 10.
11b is configured to be pivotally mounted on the pivot 12 and to rotate appropriately to open and close the air hole 10 properly.

In the embodiment constructed as described above, the object to be cooked is poured into the container body 1 together with a required amount of water such as broth, the inner lid 9 and the outer lid 6 are fitted, and the locking piece 8 is attached.
To the notch 3 to fix the outer lid 6 to the container body 1. Then, it is placed in a required microwave oven and irradiated with microwaves. Then, the microwave is reflected by the outer lid 6 to prevent excessive microwave irradiation from the upper surface, while the microwave absorbing and heating element layer 4 is heated, and an appropriate amount of microwave is passed through the non-microwave absorbing and heating part 5. By irradiating the inside of the container body 1 to appropriately suppress the early evaporation of water, the object to be cooked is appropriately heated and cooked by the heating action of the microwave absorbing and heating element layer 4 and the appropriate amount of microwave irradiation.

[0011]

According to the present invention, as described above, a deep-bottomed container main body through which microwaves can freely pass, and a lid for reflecting microwaves are provided. Since the microwave absorbing and heating element layer is formed over the required width, the microwave is reflected by the outer lid to prevent excessive microwave irradiation from the upper surface,
The microwave-absorbing heat-generating layer can be heated, and an appropriate amount of microwave can be radiated into the container body through the non-microwave-absorbing heat-generating portion as needed to heat and cook. Heating such as boiling and steaming can be suitably cooked in a microwave oven without causing excessive evaporation of water.
