Description

Microwave Dispersion Device and Method of Microwave Oven

The present invention relates to a microwave dispersion apparatus and method for a microwave oven, and more particularly, to efficiently disperse microwaves in a microwave oven so that food can always be cooked in a uniform state.

In general, the microwave oven refers to a home cooking appliance that cooks food using microwaves emitted from a magnetron to which a high voltage is applied, and such a general microwave oven is illustrated in FIG. 1.

According to FIG. 1, such a conventional microwave oven is placed in a cabinet 1 having a magnetron (not shown) inside thereof, and a container in which food is contained by being partitioned by a separate partition inside the cabinet 1. The cooking chamber 2 is coupled to one end of the cabinet 1 so as to be openable and comprises a door 43 for selectively opening and closing the front surface of the cooking chamber 2.

On the other hand, in the conventional microwave oven, the rotary dish 37 to rotate the food container in order to prevent the microwaves emitted from the magnetron and irradiated to the food in the food container inside the cooking chamber 2 concentrated only on a specific portion of the food. It is generally provided further.

2 and 3 illustrate a conventional rotary dish 37 for a microwave oven. The conventional rotary dish 37 is configured to include a dish main body 38 and a motor 4a. The plate body 38 is connected to the motor 4a by a coupler 35 which is coupled to the rotating shaft 44 of the motor 4a.

In more detail, three locking projections 39 are formed at a center of the lower surface of the dish main body 38 at intervals of 120 °, and the upper surface of the coupler 35 is sandwiched between the locking projections 39 and the motor. Three locking projections 36 for transmitting the rotational force of 4a to the dish main body 38 are also formed at 120 ° intervals.

A plurality of rollers 40 are interposed between the dish body 38 and the bottom surface 3 of the cooking chamber 2 to stably support rotation of the dish body 38 with respect to the bottom surface of the cooking chamber 2. The plurality of rollers 40 are rotatably coupled to the annular roller support 41.

In addition, the plurality of rollers 40 are configured such that the rotational movement of the plurality of rollers 40 is guided by two rows of guide parts 42 protruding from the lower surface of the plate body 38.

In order to cook food using a microwave oven equipped with a conventional rotary dish 37 for a microwave oven configured as described above, a container containing food is placed in a dish main body 38 installed in the bottom surface 3 of the cooking chamber 2. When the microwave oven is placed and the door 43 is closed, the food is cooked by the microwaves emitted from the magnetron installed inside the cabinet 1.

At the same time, as the motor 4a installed under the bottom 3 of the cooking chamber 2 is operated to rotate the coupler 35 coupled to the rotating shaft 44 of the motor 4a, the dish main body 38 is rotated. As the food container rotated and placed thereon, the microwaves emitted from the magnetron are prevented from being concentrated on only a specific portion of the food.

However, such a conventional microwave oven is difficult to evenly distribute the microwaves due to the dispersion of the microwaves only by the rotation of the rotary dish 37 when cooking food, so that the difference in the degree of cooking inside and outside the food There was a problem in that the inside and outside of the cooking can not always be uniformly cooked, causing partial overcooking during cooking.

The present invention is to solve the above-mentioned problems, it is possible to effectively prevent the partial over-cooking phenomenon during cooking by dispersing microwaves efficiently in a microwave oven so that food is always cooked in a uniform state. It is an object of the present invention to provide a microwave dispersion apparatus and method for a microwave oven.

In the present invention configured as described above, as shown in FIGS. 4 to 6, in order to cook food using a microwave oven, a container containing food is placed on a plate main body 38 installed on the bottom surface 3 of the cooking chamber 2. When the microwave oven is operated after closing the door 43, food is cooked by microwaves emitted from the magnetron installed inside the cabinet 1.

At the same time, the motor 4 installed under the bottom 3 of the cooking chamber 2 is operated to receive the driving force of the motor 4 so that the supporting member 7 is centered in the housing 5 of the motor 4. As the drive shaft 8 installed to penetrate rotates, the drive gear 9 installed on the drive shaft 8 rotates, and at the same time, the rotational force of the drive gear 9 meshes with the drive gear 9, so that the housing 5 As it is transmitted to the first interlocking gear 11 installed on the first interlocking shaft 10 on the supporting member 7, the rotational force is transmitted to the interlocking gears installed so as to sequentially engage each other.
