Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high frequency heating device for heating an object to be heated with microwaves.

[0002]

2. Description of the Related Art FIG. 3 is a sectional view of a conventional high-frequency heating device. The heating chamber 1 is provided with magnetrons 2a and 2b which are high frequency generating means on the upper and lower surfaces. Further, the steam containers 5a and 5b, which are formed of a low dielectric loss material and are provided with water absorbers 3a and 3b that absorb water for generating steam inside, are provided with lids 4a and 4b having the same outer shape width in the vertical direction. , The magnetron 2a is configured to be detachably housed at the upper and lower positions of a shelf plate 7 made of a low dielectric loss material on which the object to be heated 6 is placed, the bottom surface of which is in contact with a rail 8 made of the low dielectric loss material.
With the microwave from 2b, the water in the steam containers 5a, 5b boils to generate steam, and the object 6 to be heated is heated by the steam and the microwave directly irradiated.

[0003]

However, such a configuration has the following problems.

(1) It is constructed so that the bottom surface is in contact with the rail 8, and strong microwaves radiated from the lower magnetron 2b are applied to the portion (A portion) in contact with the lower steam container 5b and the rail 8. There is a risk of direct contact, melting of that part, or sparking if food debris adheres, and in the worst case, ignition of the steam container.

(2) The upper steam container 5a appropriately supplies steam to the object to be heated 6 located below, and the lower steam container 5b appropriately supplies steam to the object to be heated 6 located above. Therefore, if the top and bottom are misused, the cooking performance will be adversely affected, but the top and bottom steam containers 5a, 5b
Since both are housed in the rail 8, the outer width is the same and there is a high possibility of misuse. It is an object of the present invention to provide a high-frequency heating device equipped with a steam generator that is safe, can produce uniform cooking results, and is easy to maintain.

[0006]

In order to achieve the above object, the present invention generates steam inside between two high frequency generating means provided on the upper and lower surfaces of a heating chamber and an object to be heated. The steam container with a lid provided with a water absorber for absorbing water is detachably housed in the upper steam container on the rails that are detachably installed on the left and right wall surfaces of the heating chamber, and the lower steam container is It is not housed, but is positioned directly on the partition plate that is locked directly above the lower high-frequency generating means, and the lower steam container has a smaller width dimension than the upper steam container. It is configured to be provided.

[0007]

According to the present invention, by arranging the lower steam container directly on the partition plate, the lower steam container and the rail are not in contact with each other on the bottom surface, and the contact surface of both is radiated from the lower magnetron. There is no danger that the generated strong microwaves will not hit directly, and that part will melt or sparks when food residue adheres, and in the worst case, ignition of the container will occur. Moreover, since the lower steam container is not configured to be housed in the rail, the outer width can be made smaller than that of the upper steam container, and the vertical misuse can be prevented.

With such a configuration, the upper magnetron 12
The microwaves generated from the a and the lower magnetron 12b heat the water in the upper steam container 15a and the water in the lower steam container 15b, respectively. As a result, the water is heated and released as steam, and the inside of the heating chamber 11 is brought into a high-humidity state, and the steam hits the food 16 from above and below to uniformly heat the entire food with steam. Upper and lower steam containers 15a and 1
The microwave that has passed through the water in 5b is evenly applied to the food 16 from above and below to heat the food 16 by microwaves.

At this time, the lower steam container 15b and the rail 18 are not in contact with each other on the bottom surface side, and the strong microwave radiated from the lower magnetron 12b does not directly hit the contact surfaces of both, so that the lower steam container 15b. Since the water hits the inside after absorbing the energy, there is no risk of ignition because the part melts or sparks when food residue adheres.

Since the lower steam container 15b is not configured to be housed in the rail 18, the outer width of the upper steam container 15a is smaller than that of the upper steam container 15a.
Since it can be made smaller, there is no fear of mistakenly using the upper steam container 15a and the lower steam container 15b, and uniform cooking results can be obtained.
