JP2002034786A - Metal hood of egg boiler for microwave oven - Google Patents

Abstract

PROBLEM TO BE SOLVED: To boil foods with shell or rind, such as an egg with a simple utensil by a microwave oven. SOLUTION: A metal hood (1) is provided with a plurality of slits (2), equidistantly spaced on the periphery of the metal hood, and notches (3) between the slits. The egg is put into a container for a microwave oven (5), water is poured into it, and then the egg is covered with the metal hood (1). When heating the egg in this state by the microwave oven, the water outside the metal hood (1) is heated faster than the water inside the metal hood. As a result, convection between the notches (3) and the slits (2) is generated to increase the inside temperature.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal container of a boiled egg device for a microwave oven, which is used for making boiled eggs directly in a microwave oven.

[0002]

2. Description of the Related Art Heating from a microwave oven generates heat from the inside of an article to be heated. Therefore, when something with a shell on the outside, such as a chicken egg, is directly heated, the inside will first become hot, generating steam and exploding. Conventionally, when making boiled eggs in a microwave oven, a method has been adopted in which water is once vaporized and steamed with the steam to produce boiled eggs. Therefore, the shape of the device is limited, and the range of use is also limited.

[0003]

(I) It was not possible to directly boil hard-shelled foods such as chicken eggs and chestnuts or husks. (B) As with quail eggs and chicken eggs, it was not easy to adapt to large and small shapes. The present invention has been made to solve the above drawbacks.

[0004]

Means for Solving the Problems A plurality of slits (2) are provided at equal intervals around a metal container (1), and an area larger than the area of the slit (2) is provided between each slit (2). Is provided in the edge (4) of the metal container (1). The present invention is a metal container for a boiled egg device for a microwave oven having the above configuration.

[0005]

When using the present invention, a container (5) with a lid for a microwave oven is used. Place the eggs (8) in the microwave container (5) and water (6) until the eggs (8) are hidden. The egg (8) is covered with the metal container (1). Then, it is placed in a microwave oven and heated. Most of the radio waves of the magnetron (7) are shielded by the metal part of the metal container (1), and the radio waves passing through the slit (2) are extremely small. Most radio waves are used to warm water (6). as a result,
A temperature difference occurs between the water (6) outside the metal container (1) and the water (9) inside, and the water (9) inside flows out of the notch (3) as shown by the arrow. The warm outer water (6) flows into the metal container (1) through the slit (2). This convection continues and the egg (8) is boiled up without bursting.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below. (A) A bowl-shaped metal container (1) is made of a durable metal such as stainless steel. The bowl shape has a larger effective internal volume than a spherical shape such as an egg. (B) Four slits (2) are provided at equal intervals in the metal container (1). (C) The width of the slit (2) is 5-6, which is the sum of the widths of the four slits (2) with respect to the midpoint of the height of the metal container (1) and the length of the circumference on AB. %. In the embodiment shown in the drawing, the circumference of 360 mm on AB and the total width of the four slits (2) is 20 mm. (D) The upper and lower lengths of the slit (2) are such that the lower end is the same as the upper part of the notch (3) and the upper end is just before the uppermost part of the metal container (1). In the embodiment, the length is 40 mm. (E) Notches (3) at equal intervals on the edge (4) of the metal container (1)
Are provided at four locations. In the embodiment, it is 10 mm in length and 50 mm in width from the edge (4). The present invention has the above configuration. When the present invention is used, a microwave oven container (5) with a lid is used. Heat loss due to evaporation of water (6) is reduced, and it is also useful for preventing discharge in the microwave oven. Microwave oven container (5)
Is slightly larger than the maximum diameter of the edge (4) of the metal container (1). Microwave ovens that are now widely used in ordinary households are:
A turntable type having a radio wave oscillator by a magnetron in a diagonally upper part in a refrigerator is generally used. The intensity of the radio wave emitted to the egg (8) in the metal container (1) depends on the ratio of the width of the metal part of the metal container (1) to the width of the slit (2). It is thought to be less than one tenth. Further, since the microwave container (5) containing the metal container (1) rotates in the same manner as the turntable, the radio wave applied to the egg (8) is intermittent. The same applies to the water (9) inside the metal container (1).
Therefore, compared to the water (6) outside the metal container (1) that continuously receives the irradiation of all radio waves, the radio waves of the eggs (8) and the water (9) around the eggs (8) are used. The calorific value is extremely small. The egg (8) does not burst because the temperature inside the egg (8) rises more slowly than the temperature inside the water (9) due to convection caused by the temperature difference between the water inside and outside the metal container (1). .

[0007]

[Effect of the present invention] By using the present invention, it is easy to boil foods such as eggs and chestnuts, which have been said to be difficult in a microwave oven, as in the case of direct gas fire. You can use a microwave oven. Microwave ovens can easily set the heating time with a timer compared to gas, and have the great advantage that boiled eggs can be made even if left unattended. Boiled eggs such as quail eggs can be made as easily as chicken eggs by changing the amount of water and heating time.
