DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided electric cooker for baking fish and the like.

[0002]

2. Description of the Related Art Conventionally, an electric cooker of this type generally has a configuration as shown in FIG. That is, an upper container 4 having an upper heating element 1 inside and a catalyst body 2 on the top surface and an exhaust fitting 3 covering it, a lower container 6 having a tray container 5, and an upper portion of the tray container 5. A lower heating element 8 is located between the grill 7 and the saucer container 5 and the grill 7, and the upper container 4 can be opened and closed by a hinge (not shown) provided at the rear.

[0003] In the above configuration, cooking is performed by placing fish 9 or the like on the grill 7 and energizing the upper heating element 1 and the lower heating element 8.

[0004]

When baking fish in such a conventional electric cooker, since the temperature of the saucer container 5 is also increased by the lower heating element 8, the fish oil flowing out of the fish 9 is consumed by the lower heating element 8. When dropped on the top or the tray container 5, oily smoke is generated and rises naturally and passes through the catalyst body 2. However, if the smoke is concentrated in one place or a large amount of oil smoke is generated at one time, the surface of the catalyst 2 and the oil smoke cannot all contact with each other, and the catalyst 2 cannot completely purify and oxidize and purify the oil smoke. Some were discharged outside the cooking cabinet without purification. In addition, when the generated oil smoke does not flow smoothly toward the catalyst body 2 and accumulates in the cooking chamber, the pressure loss increases, so that the oil smoke leaks from the periphery of the upper container 4 and the speed increases even when passing through the catalyst body 2. Because of its speed, it was discharged outside the cooking cabinet without purification.

The temperature of the catalyst body 2 is increased by the upper heating element 1, but since the shapes of the catalyst body 2 and the upper heating element 1 do not match, the temperature of the catalyst body 2 rises uniformly and sufficiently. However, the oil smoke that passed through the place where the temperature of the catalyst body 2 was low was discharged to the outside without being purified. In addition, when water is put into the saucer container 5 for cooking, the temperature of the water rises and a large amount of steam is generated, which deteriorates the performance of the catalyst 2 with respect to the catalyst 2 or is discharged out of the cooking chamber as smoke. There was a problem that would. In addition, when such a state is repeated, there is a problem that the upper container 4 is immediately contaminated with oily smoke and smell is attached.
