Microwave Oven

(Utility model)

An egg cooker (utility model) for a microwave oven is a cooking device.

Known egg cooker, consisting of two different-sized metal pots. A large pot is filled with water to a predetermined level and the water is heated to a boil, for example, on a gas stove. The eggs to be cooked are placed in a smaller saucepan, scoop up boiling water from a large saucepan, and then the small saucepan is placed inside the large saucepan. Lids for pots are not provided. After the set time has elapsed, the egg cooking process is automatically interrupted by a special mechanism acting as a timer 1.

The use of this device for cooking eggs in a microwave oven is unacceptable due to the fact that microwave radiation does not penetrate the walls of metal utensils. Cooking eggs due to microwave radiation penetrating into an open metal pan from above is impossible due to the fact that during the interaction of microwave radiation with products in the shell or in the shell, the latter explode. (The instructions for microwave ovens contain a special warning in this regard).

A microwave oven is known, consisting of a microwave-transparent glass container for water, for example, installed inside this container of an egg tray made of metal, a material opaque to microwave radiation, the water tank being provided with a metal lid, which is completely covered from the top closes microwave path to product and water to be heated. A separate cell of a cup-shaped shape is provided in the metal tray for placing each egg, and there are no holes in the walls of these cells through which heated water or steam could directly con Leon Leonid Fedorovich

Tact with eggs to be cooked. Water in a glass container is located under the tray and is heated only by reflected lateral microwave radiation, and the tray and the eggs themselves are heated by the steam generated during boiling water. At the end of cooking, remove the lid from the glass container and then use the two forks to remove the egg tray 2.

The disadvantage of the above egg cooker is that in it the water to be heated is largely shielded from the effects of microwave radiation by the metal elements of the device. Another disadvantage of the known egg cooker we see in the low efficiency mediated through steam heating and cooking eggs.

An egg cooker for microwave oven 2 is considered as a prototype for our utility model.

The objective of our proposal is to simplify the design and increase the efficiency of the process.

When realizing the task, a positive technical result is achieved due to the fact that in the well-known egg cooker consisting of a main container for water transparent for microwave radiation, another container for the product is installed inside this container, which is protected from the microwave by a lid on top, and the container for the product and the lid is made of a material opaque to microwave radiation, for example, metal, the walls and the bottom of the product container are perforated, and the cross-sectional area The value of the main capacity in its widest part exceeds the area of this section covered by the lid by a given value.

The essence of the utility model is illustrated by drawings, where: in Fig.1 shows the 1st embodiment of the egg cooker, in section; in FIG. 2-2nd embodiment of the egg cooker, in the context; in FIG. 3 - a tool for installing and removing the egg container from the main vessel, general view; in FIG. 4 - the same, bottom view.

The egg cooker, made according to the first embodiment, consists of a cylindrical glass cup 1, transparent for microwave radiation, in the center of which a metal cylindrical container 2 for eggs 3 is installed. Numerous perforations 4 with a diameter of not more than 3 mm are made in the walls and bottom of the metal container through which during cooking, interchange of different temperature flows of water between containers 7 and 2. (Made in the container body 2 numerous holes with a diameter not exceeding 3 mm, almost completely eliminate penetrate through them microwave radiation, the frequency of which in microwave ovens is 2450 MHz 2, 3). The tank 2 is equipped with legs 5 and a metal cover 6. The holes for the release of steam (with a diameter of less than 3 mm) are made in the cover 6 or in the walls of the inner container 2 directly under the edge of the cover. Glass and metal containers in cross section can be not only round, but also have, for example, a square shape.

The inner container 2 can also be made of a fine-mesh metal mesh impervious to microwave radiation from the furnace.

Eggs 3 are laid in the inner container 2, after which it is placed in the outer container 1. The required volume of water of room temperature is poured into the egg cooker through the container 2, which also enters the outer container through the numerous openings in the walls and bottom of the inner container. The metal container 2 is covered with a lid b, the egg cooker is placed in the microwave and the desired cooking mode is set. The primary heating of the water filling the space between the walls of the outer and inner containers is carried out by microwave radiation emanating both from above, directly from the waveguide of the furnace, and radiation previously reflected once or several times from the inner walls of the furnace chamber. Due to convection through numerous openings in the walls and bottom of the inner tank 2, the water temperature in it after a while reaches the required values. At the end of cooking, remove the lid from the egg cooker

6 and the metal container 2 is removed from the glass container 1. At the same time, hot water is allowed to completely drain from the container 2. After that, the boiled eggs 3 are cooled with cold water.

In FIG. 2 shows a second embodiment of an egg cooker. A widespread glass container 7 with a glass lid 8 and handles 9, specially designed for use in microwave ovens, was taken as the main container. a groove 14, and on top the container is closed with a metal cover 15 with an opening in the center for the rack 13. Two handles are fastened on the cover 16. Between the rack 13 and the walls of the central hole in the cover 75 there is a gap for steam to escape. Numerous perforations 17 with a diameter of not more than 3 mm were made in the walls and bottom of the container 10, through which during the cooking process interchange of different temperature flows of water between the containers 7 and 10. At the bottom of the metal container 10, separate cup-shaped recesses can be made for each egg.

To install and remove the tank 70 from the main tank 7, a hoist equipped with a handle 78 is provided (Fig. 3, 4), on the plate working element 79 of which a longitudinal open slot 20 is made, the width of which is 0.2-0.6 mm larger than the diameter of the rack 73 at the level of the groove 14, but significantly less than the diameter of the rack above the groove. The free end of the working element 79 is bent at a given angle towards the handle.

When using the lift, its working element 79 is brought into the groove 14 of the rack 73. After that, with the help of the lift, you can easily and conveniently manipulate the tank 10 (raise, lower and move horizontally).

Microwave the eggs using the egg cooker shown in FIG. 2 are carried out as follows. In the main container 7, a metal container 10 with eggs 3 laid in it and closed with a metal cover 75 is placed. Then, a predetermined amount of water is poured into the egg cooker, closed with a glass cover 8, placed in a microwave oven and the desired cooking mode is set. Due to the convection of heated water, from the very first minutes after turning on the microwave oven, eggs 3 begin to be exposed to heat. At the end of cooking, the egg cooker is removed from the oven and the lid is removed 8. Using an elevator (Figs. 3, 4), the inner vessel 10 is removed from the main vessel 7, allowing the water filling it to completely drain. After that, the lid 15 is removed and then the cooked eggs are cooled with cold water.

In an egg cooker of the above construction, we cook hard-boiled eggs at a microwave output of 450 W for 11-12 minutes. Initially, room temperature water is poured into the egg cooker.

In the proposed egg cooker for the microwave oven, in contrast to the known egg cooker 2, the egg is cooked more efficiently, because the water is heated not only due to reflected lateral microwave radiation, but also due to radiation directed from above. In a well-known egg cooker, heating and cooking of eggs is carried out due to steam, for the formation of which in sufficient quantities a certain time is required. In the proposed egg cooker, the eggs are placed directly in the water, which is heated by microwave radiation and, therefore, the cooking process begins from the first minutes after turning on the oven.

The proposed device can also be used for cooking products in the shell, such as sausages.
