The present invention relates to a microwave uniform heating apparatus, and more particularly, to a uniform heating apparatus for cooking food evenly when heating food using a microwave oven.

In a conventional microwave oven, when microwave radiation emitted from a magnetron enters a cavity through a waveguide in order to cook food, there is one inlet through which the microwave wave can enter, so that the stir pan reflecting this microwave wave is Even if the function is performed in perfect summer, the microwaves are concentrated in one place and the food is not evenly cooked.

The present invention has been made in view of the above-mentioned point, and installs 2-3 waveguides for transmitting microwave waves radiated from the magnetron, and delivers them into the cavity, and uniformly distributes the microwave waves that enter the cavity with a strut formed in the cavity. It is an object of the present invention to provide a uniform heating device capable of uniformly distributing food.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

Example 1

As shown in Figs. 1 and 2, (1) is a cavity, in which the waveguides 2, 2 'are integrally formed on the upper and side surfaces between the cavity 1 and the magnetron 4; Form and install.

At this time, the length b of the waveguide 2 'formed on the side surface is formed so as to be b 길 2a by calculating the limit wavelength length a of the microwave wave generated by the magnetron 4.

In this way, there is no loss when microwaves are transmitted.

As shown in FIGS. 1 and 2, one or several long holes 7 and 7 ′ are formed on the surface of the cavity 1, so that the inside of the cavity 1 and the waveguide 2 are formed. , (2 ') is always connected.

In addition, a normal strut fan 3 is provided inside the cavity 1.

The operation of the present embodiment was as follows.

First, the microwave wave generated in the magnetron 4 is introduced into two places of the top and side surfaces of the cavity 1 along the waveguides 2 and 2 'and through the long holes 7 and 7'. It is distributed evenly in the cavity 1 by the strut pan 3, so that the food 5 is cooked evenly.

Example 2

As shown in FIG. 4 and FIG. 5, the same code | symbol was attached | subjected to the member which has a function similar to Example 1 except the waveguide similarly to the structure of Example 1. FIG.

The waveguides 22 and 22 'are integrally installed on the top, side, and back of the cavity 21, and the waveguides 22, 22' and the inside of the cavity 21 are always connected to each other. Long holes 27 and 27 'are formed in the cavity 21 surface.

The operation of this embodiment is almost the same as in Example 1.

Example 3

As shown in FIG. 7 and FIG. 8, except for the waveguide and the strut pan, the members having the same functions as those of the first embodiment and the second embodiment are almost similar to those of the first and second embodiments. Signed.

The waveguides 32 and 32 'are integrally installed on the top and bottom surfaces of the cavity 31, and long to connect the waveguides 32 and 32' to the inside of the cavity 31 at all times. Holes 37 and 37 'are formed in the cavity 31 surface.

In this way, there is no loss when microwaves are transmitted.

In addition, the strut pans 33 and 33 'are provided on the top and bottom surfaces of the cavity 31, respectively, and the food 35 is placed in the cavity 31 to transmit microwave waves. The base plate 36 which can be made is installed so that it may be located in the upper part of the strut pan 33 'installed in the bottom surface.

Referring to the operation of the present embodiment is as follows.

First, the microwave wave generated from the magnetron 34 is introduced into the top, side, and rear surfaces of the cavity 31 along the waveguides 32 and 32 'and through the long holes 37 and 37'. After being introduced into the inner surface of the cavity 31, it is evenly distributed in the cavity 31 by the strut pans 33 and 33 ', so that the food 35 is cooked evenly.

As described above, according to the present invention, the microwaves generated in the magnetron not only enter the cavity through the waveguides on the top, the side, or the back, but are evenly distributed by the strut pan, so that the food can be cooked uniformly.

Claims (2)
