Title: Grill pan structure

Description:
BACKGROUND OF THE INVENTION 
     Field of Invention 
     The present invention relates to a grill pan, and more particularly, but not exclusively to a grill pan structure, suitable for kinds of foods, to prevent to turn over the foods during roasting and easy to clean. 
     Related Art 
     In general, when baking foods, if placed on a flat pan, it often produces uneven heating of the upper and lower sides. Since the flat pan dose not have openings, which the heat could not pass through, the surface of the foods, attached to the pan, is over/poor heating. Also, the oils generated from foods during heating will remain in the pan. The food may be spoiled after prolonged heating. And if baking a variety of foods at the same time, the generated oils will contaminate other foods. It is not only unhealthy but also affect food flavor. 
     If the grill grid is used to support the foods, the foods can be heated more evenly. However, the generated oils will drip into the baking device. It is dangerous and not easy to clean. Moreover, when uneven heating, it may have to extend the baking time or turn over the foods repeatedly. It wastes of resources and is not convenient to use. 
     For the conventional pan, it is usually plat and dish-shaped. The heat generated form the below heat source is not easy to reach the foods, because the heat cannot pass through the pan. Therefore, the heat efficiency is very low. It needs more time to finish baking. The time and the energy are wasted. Therefore, there is a need to improve the pan of the oven. 
     SUMMARY OF THE INVENTION 
     The present invention overcomes the above-described and other problems and disadvantages in the conventional grill pan by providing a grill pan structure to heat foods uniformly within the oven. 
     Accordingly, the present invention provides a grill pan structure, includes a heat flow layer and at least one support plate. The heat flow layer includes at least one hole for a heat source to pass through to make uniformly heating and eliminate from turning over the foods. Also, the heat flow layer includes at least one recess to receive the dropped oils of the foods during roasting to keep the oven clean.

However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

     DETAILED DESCRIPTION OF THE INVENTION 
     Please refer to  FIG. 1A , a schematic view of a first embodiment of the grill pan structure of the present invention is shown. 
     The grill pan structure of the present invention is adapted to support an item for roasting. The grill pan includes a heat flow layer  10  and a first support plate  20 . The heat flow layer  10  further includes at least one hand grip  13  and at least one protruding portion  15  disposed on a suitable location of the side thereof. The heat flow layer  10  also includes at least one hole  11  for a heat source to pass through and at least one recess  12  to receive a dropped oil of the item during roasting. The first support plate  20  is disposed on the heat flow layer  10  to support the item. The first support plate  20  also has at least one hand grip  22  disposed on a suitable location of the side thereof. The first support plate  20  includes at least one inclined guiding surface  21  corresponding to the recess  12  and guiding the dropped oil to the recess  12 .  FIG. 1B  is an exploded view of a first embodiment of the grill pan structure of the present invention. 
       FIG. 2  is a cross-sectional view of a first embodiment of the grill pan structure of the present invention. 
     As shown in  FIG. 2 , the grill pan structure of the present invention includes the heat flow layer  10  and the first support plate  20 . The item is supported by the first support plate  20 . The above heat source may heat the item directly. And the below heat source may pass through the hole  11  of the heat flow layer  10  to heat the item. The dropped oil of the item during roasting would be guided by the inclined guiding surface  21  to the recess  12 . 
     Please refer to  FIG. 3 , a schematic view of a second embodiment of the grill pan structure of the present invention is shown. As shown, the grill pan structure of the present invention includes the heat flow layer  10  and the first support plate  20 . The heat flow layer  10  includes at least one hole  11  for a heat source to pass through and at least one recess  12  to receive a dropped oil of the item during roasting. The bottom of the first support plate  20  is flat to easy to place. The first support plate  20  is disposed on the heat flow layer  10  to support the item. The first support plate  20  also has at least one hand grip disposed on a suitable location. The first support plate  20  includes at least one cone-shaped inclined guiding surface  21  corresponding to the recess  12  and guiding the dropped oil to the recess  12 . 
     Please refer to  FIG. 4 , a schematic view of a third embodiment of the grill pan structure of the present invention is shown. The grill pan structure of this embodiment is integrated and includes the heat flow layer  10 . The heat flow layer  10  includes at least one hole  11  for a heat source to pass through and at least one recess  12  to receive a dropped oil of the item during roasting. Moreover, the heat flow layer  10  includes a plurality of supporting ridges  14  to support the item. The inclined guiding surface  21  is extended from the supporting ridges  14  and integrated with the recess  12  to guide the dropped oil to the recess  12 . 
     Please refer to  FIG. 5A , a schematic view of another example of the first embodiment of the grill pan structure of the present invention is shown. The structure of this example is the same with the structure shown in  FIG. 1A . The grill pan includes a heat flow layer  10  and a first support plate  20 . The heat flow layer  10  further includes at least one hand grip  13  and at least one protruding portion  15  disposed on a suitable location of the side thereof. The heat flow layer  10  also includes at least one hole  11  for a heat source to pass through and at least one recess  12  to receive a dropped oil of the item during roasting. The first support plate  20  is disposed on the heat flow layer  10  to support the item. The first support plate  20  also has at least one hand grip  22  disposed on a suitable location of the side thereof. A second support plate  30  is disposed on the first support plate  20 . As shown, the second support plate  30  has fine grids, which is suitable for small size foods.  FIG. 5B  is an exploded view of another example of the first embodiment of the grill pan structure of the present invention. 
       FIG. 6A  is a schematic view of the grill pan structure of the present invention when combined with an oven. The protruding portion  15  of the heat flow layer  10  can be placed on the rack  41  of the oven  40  for normal use. Please see  FIG. 6B , in case of the size of the heat flow layer  10  does not match the oven  40 . The protruding portion  15  cannot be placed on the rack  41 . The grill pan structure may be placed on the grid  42  of the oven  40  directly. 
     Accordingly, the present invention provides a grill pan structure to make the heat source pass through the grill pan for roasting uniform. Also, the oils may fully separate from the foods so that users would handle different foods at the same time without influencing with each other. The convenience of cooking is improved due to the convection heating to eliminate from turning over the foods and waiting aside. Also, seasonings may be add in the recess to smoke the foods during roasting. 
     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
