Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of drain pans in a roaster that receives meat juice generated during grilled meat cooking.

[0002]

2. Description of the Related Art Conventionally, a heating method using charcoal or ceramic charcoal has been put into practical use for heating meat placed on a net or a roast, and a roaster of this heating method has a burner arranged in the lower part and an intermediate part. In addition to the charcoal or the ceramic charcoal, the combusted material and the radiant material were arranged. As a method of arranging the burned material and the radiant material, the pot body is locked to the annular stepped portion provided at the upper end of the inner box, the pot body is opened at the center lower part, and the peripheral portion has a low descending curvature and gradually descends. It has a funnel shape with a reduced diameter, and a placing portion for the combustion products and radiant products is provided below the reduced diameter portion. Then, a supporting tool is provided on the placing part to place the charcoal combustion product, and a burner for ignition is provided at the lower part thereof, or the radiant material such as ceramic charcoal, lava, and rock is placed on the supporting tool, and at the bottom part. There was a burner for heating the radiation. The burner was formed into a ring shape and the crater of the gas flame was placed outside the vase to prevent the fallen gravy from adhering.

[0003]

In the above roaster, there is a heated product in the center and a pot with a relatively low heating amount is present in the peripheral part, and especially when cooking meat, a large amount of oil and fat is added. When the contained meat was heated, the gravy dropped on the central heating material and the peripheral portion of the pot. The gravy that falls in the central part adheres to the heated product, or passes between heated products and drops into the lower drain pan, while the gravy that drops in the peripheral part adheres to the peripheral part of the pot and part of it It flows down along the reduced diameter inclined surface of the jar. When the amount of fallen gravy around the jar with a low descent curve becomes large, the gravy adhering to the periphery ignites or the fire continues for a short time because some of the gravy flowing down may come into contact with the heated material. There was a risk of

In summary, according to the present invention, the lower drain pan 16 is arranged in the lower part of the inner box 6, the upper drain pan 11 having a ring shape in plan view is provided inside the upper part of the inner box 6, and the inner peripheral upper end of the upper drain pan 11 is provided. Since the pot body 60 is provided in the pot body 60, and the heating substance (ceramic charcoal 61, 61a ... or charcoal charcoal 64, 64a ...) is stored in the pot body 60, the burner 18 is arranged below the pot body 60.
The oil-and-fat-containing gravy generated from meat around the Lostor 15 is a ring-shaped upper drain pan 11 provided around the periphery.
It is possible to prevent the meat juice from accumulating in the peripheral portion, which has been generated conventionally, by falling into the stored water of the water tank portion 24, and safely continue the grilled meat cooking.

The water tank portion 24 of the upper drain pan 11 is an outer peripheral wall 23,
The bottom wall 23a and the inner peripheral wall 23b are formed in a U-shaped cross section, and the bottom wall 23a
The second bottom wall 25a is provided in the lower part of the above, and the second inner circumferential wall 25b is provided on the inner circumferential side of the inner circumferential wall 23b to insulate between the bottom wall 23a and the second bottom wall 25a and between the inner circumferential wall 23b and the second inner circumferential wall 25b. Because it was part 26,
The space layer of the heat insulating portion 26 can prevent the hot air of the burner 18 from heating and evaporating the stored water in the water tank portion 24 of the upper drain pan 11 by the heat insulating and blocking action, and also the upper drain pan 11
Even if an overflow occurs when water is poured into the water tank portion 24, the heat insulating portion 26 on the inner circumference of the water tank portion 24 catches it and prevents it from falling into the burner 18.

Since the pot body 60 serves as the radiant portion and the heating material to be housed in the radiant portion 27 is made of the radiant ceramic charcoal 28, the radiant portion 27 and the ceramic charcoal 28 are heated by the burner 18, and the ceramic char 28 Far infrared rays generated from the radiation and radiant heat generated from the radiant part 27 and the ceramic charcoal 28, and the cooking gas heats the meat on the roaster 15 to heat the meat from the inside with the far infrared rays and the meat from the outside with the radiant heat. The inside and outside can be cooked in a well-balanced and juicy manner, and its practical effect is enormous.
