Description

Supporting device of cooking tray for microwave oven}

The present invention relates to a microwave oven, and more particularly, to a cooking plate support apparatus for a microwave oven.

In general, a microwave oven is a mechanism in which food is cooked by frictional heat between molecules by translating water molecules contained in food by radiating a high frequency of 2650 MHz in a magnetron into a cooking chamber.

Such a microwave is provided with a cooking chamber in which cooking is performed, and in the cooking chamber, a cooking plate 1 on which food is placed is provided, as shown in FIG. 1, and a coupling part 2 is provided in the cooking plate 1. ) Is provided is coupled to the transmission shaft 3 for transmitting the rotational force to the cooking dish (1).

In order to operate the cooking dish 1 smoothly, the lower portion of the cooking dish 1 is provided with a cooking dish 1 support device. The supporting device of the cooking dish 1 has three rollers supporting the cooking dish 1. And a guide ring (5) for maintaining a constant distance between the roller (4), the roller 4 is rotated while drawing a constant trajectory about the transmission shaft (3) on the lower surface of the cooking chamber. The guide groove 6 is provided so that it may be made.

The supporting device of such a structure is that when the load of the food acts on the cooking dish 1, the load of the food is distributed and supported by the transmission shaft 3 and the three rollers 4, and the cooking dish 1 is stably It will work.

However, if the food is placed on a portion which is not supported by the roller 4, such as the 'A' part, due to a user's mistake or need, the load P is not dispersed and is inclined outwardly. Accordingly, there is a problem that foods placed on the cooking plate 1 may be slid out from the cooking plate 1.

The present invention is to solve such a problem, the object of the cooking dish support device to prevent the cooking plate from being inclined severely even if the food is placed to one side in the cooking dish to prevent the load is not dispersed by the roller It is to provide a microwave having a.

The present invention for achieving the above object, the main body having a cooking chamber having one side open inside, a cooking plate rotatably installed in the cooking chamber, a plurality of rollers for supporting the cooking plate, ring shape and the In the microwave oven provided with a guide ring provided at regular intervals,

The guide ring is provided with a support jaw for preventing tilting of the cooking dish.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

As shown in FIG. 2, the microwave oven according to the present invention is provided with a cooking chamber 20 and an electrical equipment compartment 30 inside the main body 10, wherein the cooking chamber 20 is opened so that the front surface of the main body 10 is opened. A turntable type cooking dish 21 is provided to raise the food therein and to make uniform cooking. And the door 40 is hinged to the opening of the cooking chamber 20 to open and close the cooking chamber 20.

The electrical equipment room 30 is formed to be partitioned on one side of the cooking chamber 20, which includes a magnetron 31 emitting high frequency radiation to the cooking chamber 20 and a high voltage transformer 32 applying a high voltage to the magnetron 31. The cooling fan 33 etc. which cool an electric component are provided. In addition, a control panel 34 configured with a plurality of operation buttons is mounted on the front part of the main body 10 facing the front side of the electronic equipment room 30 to control all functions of the microwave oven.

In such a microwave oven, as shown in Figure 3, the cooking plate 21 is provided with a coupling portion 22 is connected to the transmission shaft 23 for transmitting the rotational force, when the cooking plate 21 is rotated It is equipped with a supporting device at the bottom so as not to tilt to one side.

The cooking plate 21 supporting device is provided under the cooking plate 21 in the cooking chamber 20. The guide ring keeps the distance between the roller 24 and the roller 21 supporting the cooking plate 21 constant. 25, the roller 24 and the guide ring 25 are composed of a guide groove 26 provided on the lower surface of the cooking chamber so as to rotate by a constant trajectory.

The roller 24 is provided at least one equidistant from the center of the cooking plate 21 to prevent the cooking plate 20 is tilted by the eccentric to support the lower side of the cooking plate 21.

Such a roller 24 must be provided so as to be able to always maintain a constant distance from each other to support the cooking plate 21, which enables this is the guide ring 25.

The guide ring 25 is provided in a ring shape and the rollers 24 are installed at regular intervals so that the distance between the rollers 24 is kept constant even when the cooking dish 21 rotates.

In addition, the roller 24 and the guide ring 25 coupled as described above should always maintain a constant distance with the transmission shaft 23. For this purpose, by providing a circular guide groove 26 in the lower part of the cooking chamber 20, The roller 24 and the guide ring 25 can always rotate while drawing a constant trajectory.

In addition, according to the present invention, the guide ring 25 is provided with support jaw 27 extending up and down from the guide ring 25 in the center of the two adjacent rollers 24, respectively.

In this case, the support jaw 27 may prevent the inclination of the cooking dish 21 to some extent even if only one of the upper and lower sides is provided, but the roller 24 and the guide ring 25 may rotate along the guide groove 26. At this time, it is advantageous for the purpose of preventing the inclination to extend as long as the support jaw 27 does not contact the cooking plate 21 and the lower surface of the cooking chamber 20.

Therefore, it is preferable that the support jaw 27 extends both up and down from the guide ring 25, and the height of the support jaw 27 is slightly different from the height of the roller 24 as shown in FIG. 4. It is preferable to provide as low as t).

Support jaw 27 may be provided over the entire guide ring 25, but it is preferable for the purpose of the present invention to have a predetermined length in the central portion of the roller 24 that is not supported by the roller 24 Do.

The following describes the operation of the microwave oven provided with the support jaw 27 as described above.

As shown in FIG. 4, when food is placed in the 'B' portion of the cooking plate 21 that is not supported by the roller 24, the cooking plate 21 is inclined to one side. When the degree is inclined, the cooking plate 21 comes into contact with the supporting jaw 27 protruding upward from the guide ring 25, and thus the guide ring 25 is inclined together with the cooking plate 21.

When the guide ring 25 is inclined, the support jaw 27 extending downward of the guide ring 25 comes into contact with the bottom surface of the cooking chamber 20, and thus the cooking plate 21 stops from tilting.

Thus, the occurrence of a problem such as the slipped food on the cooking plate 21 slips from the cooking plate.

As described above in detail, according to the present invention, the support jaw extending up and down from the guide ring is provided at the center of the roller of the guide ring, so that food is placed on the support jaw even when the food is placed on the cooking plate of the portion which cannot be supported by the roller. It prevents it from being inclined so much that it can be cooked stably without damaging food spills.
