The present invention relates to a cooking chamber structure of a microwave oven in which a cooking apparatus for induction heating food by a high frequency electric field is improved.

In a microwave oven, a sealed spherical cooking chamber is constituted, the high frequency generated from the magnetron is supplied through the waveguide, and the food in the room is cooked.

However, in order to cook food evenly in cooking, high frequency should be irradiated evenly over the whole food. At present, the method of investigation is divided into two types, which are generally divided into two types. The method of heating and distributing the rotating fan and distributing the high frequency from the waveguide into the room is distributed and heated. Another method is to install a turntable on which the food is mounted on the bottom of the cooking chamber and rotated. The high frequency of the food rotates to be irradiated evenly.

However, when the high frequency is irradiated to the heated object, that is, the food in both the above and after described above, the high frequency is irradiated downward from the ceiling of the cooking chamber.

Therefore, the high frequency is irradiated to the upper portion of the food, but not reach the bottom of the food is immature occurs, there was a problem to cook the food uniformly as a whole.

In addition, since a spray fan or a turntable is installed to evenly irradiate high frequency food, the structure of the cooking chamber becomes complicated, and thus, manufacturing is not easy and manufacturing costs are increased.

The present invention has been made in view of the above problems, and its object is to simplify the structure of the cooking chamber and to provide a cooking chamber structure that allows food to be cooked uniformly by uniformly dispersing high frequency in the cooking chamber.

That is, the present invention consists of an elliptical shape having a predetermined radius of curvature inside the cooking chamber and directly installing a magnetron at a predetermined inclination angle on one side of the center line of the cooking chamber.

In particular, the present invention separates the body of the cooking chamber into an upper and lower body on a circular arc surface having a predetermined radius of curvature, and welds the upper and lower bodies to each other to form an elliptical cooking chamber, and a magnetron is provided on one side of the cooking chamber. Since the high frequency generated in the magnetron is diffusely reflected by the inner surface of the curvature radius of the cooking chamber, the high frequency dispersion efficiency is excellent and the food is uniformly cooked by irradiating the high frequency uniformly.

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

The figure shows a microwave oven for heating food by a high frequency electric field. In FIG. 3, 1 is a microwave oven main body.

The microwave oven main body 1 is configured such that the cooking chamber 2 is sealed in the inside thereof, and the front surface of the cooking chamber 2 is opened and closed by the door 3.

In addition, the cooking chamber 2 is divided into upper and lower bodies 2A and 2B on an arc surface having a predetermined radius of curvature in which high-frequency inferior reflection is smoothly formed as shown in FIGS. 2 and 3. , The ends of each of the above-described lower bodies 2A and 2B extend their ends to integrally form the joining frames 2A-1 and 2B-1, and the joining frames 2A-1, (2B-1) are welded to each other to form the cooking chamber 2.

As described above, when the upper and lower bodies 2A and 2B are joined to each other, the body of the cooking chamber 2 is formed in an elliptical shape, and the upper and lower bodies 2A, ( The end of 2B is bent outward to form joining frames 2A-1 and 2B-2, and the rear wall 4 is welded to the joining frames 2A-2 and 2B-2. .

In addition, the front end of the cooking chamber 2 is bent outward to the front end portions of the upper and lower bodies 2A and 2B to form the joining frames 2A-3 and 2B-3, and the joining frames 2A-3 The front body 5 is welded to (2B-3).

Then, as shown in FIG. 4, the magnetron 6 is installed in one side wall on the horizontal center line of the cooking chamber 2 so as to penetrate directly into the cooking chamber 2, and the magnetron 6 is graded at a predetermined inclination angle on the horizontal centerline of the magnetron. The high frequency oscillated in the magnetron 6 is installed at a predetermined inclination on the gradient inner surface of the cooking chamber 2, and the high frequency incident on the inner surface is reflected back to the other wall surface and is diffusely reflected in the cooking chamber to distribute the high frequency evenly in the room. Since the high frequency is uniformly irradiated to the food (6) is to disperse the food evenly as a whole.

In addition, in the cooking chamber 2 as described above, since the structure thereof is very simple, a microwave oven can be obtained easily and easily and inexpensively.

Meanwhile, FIG. 5 shows another embodiment of the present invention. The wall surface of the cooking chamber 22 is formed of a polygonal surface 22A close to a predetermined radius of curvature, and the magnetron 6 is installed at the polygonal surface at a predetermined position. Like the effect, high frequency diffuse reflection can be achieved to obtain a uniform high frequency dispersion effect.

As described above, according to the cooking chamber structure of the microwave oven according to the present invention, the cooking chamber is configured in an elliptical shape having a predetermined radius of curvature and the magnetron is directly installed in the elliptical cooking chamber so that the high frequency oscillated from the magnetron is diffusely reflected in the cooking chamber. In addition to excellent dispersion effect of high frequency, there is an effect of excellent heating efficiency, such as to cook foods uniformly as a whole.
