Title: Dual burner grill

Description:
BACKGROUND OF THE INVENTION  
      The present invention relates to a dual burner grill. More particularly, this invention relates to a dual burner grill that has two burners in one case.  
      Usually the different types of dish or food material require appropriate grills. A tough and wide grill is needed to barbeque a big chunk or slice of meat while a light and small one is enough to cook some mushroom. Also, in order to working on a large cauldron, we need large burner, and small one for a tiny pot.  
      A kitchen crowded with many equipments, food materials, cookers, and even cooks is not a good place to waste any surface for extra grill. Grills strewn all over the places of the kitchen are dangerous, too. Still, the cooks need many kinds and sizes of fiery surfaces to cook on.  
      Is there any way to harmonize the two colliding requirements of the above? 
      The present invention is to provide a solution to that problem.  
      Accordingly, a need for a dual burner grill has been present for a long time considering the necessity of them in our everyday life. This invention is directed to solve these problems and satisfy the long-felt need.  
     SUMMARY OF THE INVENTION  
      The present invention contrives to solve the disadvantages of the prior art.  
      An object of the invention is to provide a dual burner grill.  
      Another object of the invention is to provide a dual burner grill which accommodates two different shapes of burners.  
      Still another object of the invention is to provide a dual burner grill which is convenient to discard the waste oil.  
      A dual burner grill for cookers or foods on a tabletop includes a first burner prop including a first top-open receptacle, a second burner prop including a second top-open receptacle, a first burner fitted into the first top-open receptacle of the first burner prop, and a second burner fitted into the second top-open receptacle of the second burner prop. The first burner prop surrounds the second burner prop.  
      The first burner prop is adapted to support the cookers. The first top-open receptacle includes a groove of the shape of the first burner.  
      The second burner prop is adapted to support the cookers. The second top-open receptacle includes a groove of the shape of the second burner.  
      The first burner includes a gas burner, and the gas burner includes a pipe, holes along the pipe, and a connecting part. The second burner includes a gas burner, and the gas burner includes a pipe, holes along the pipe, and a connecting part.  
      The first burner prop and the second burner prop are disposed below the plane defined by the tabletop.  
      The first burner is rectangular, and the second burner is circular.  
      The dual burner grill further includes a first grill top over the first burner prop, a second grill top over the second burner prop, a lid for covering the first and second burners, and a waste oil sump below the first and second burner prop.  
      The first grill top is detachable. The first grill top includes a grid of holes. The first grill top is made of metal. The metal includes cast iron. The second grill top is detachable. The second grill top includes a tripod.  
      The waste oil sump is extractable from under the first and second burner prop.  
      The first and second grill tops are made of cast aluminum. The first grill top is adapted to support the cookers or food.  
      The dual burner grill further includes a case, and one or more main gas pipes. The case encloses the first and second burners, the first and second burner props, the first and second grill tops, and the waste oil sump. The case includes a front plate, a rear plate, two side plates, and a bottom plate. The main gas pipes provides fuel gas to the burners.  
      The case is covered on the top by the first grill top.  
      The front, rear, side plates of the case include a grid of holes. Each of the grid of holes has a shape of rectangle, and the size of the rectangle is approximately three (3) to five (5) by a quarter (0.25) to three quarters (0.75) inches.  
      The waste oil sump is inserted into a hole, from the front side of the case, provided on the bottom plate of the case. The length of the waste oil sump along the front plate is approximately from fourteen (14) to sixteen (16) inches. The width of the waste oil sump along the side plate is approximately from ten (10) to twelve (12) inches. The height of the waste oil sump is approximately a half (0.5) to one (1) inches. The waste oil sump includes a handle.  
      The side plate includes one or two holes for the main gas pipes that lead to the first and second burners. The size of the holes is approximately a half (0.5) to one point five (1.5) inches in diameter. The case further includes a pipe support plate for supporting the main gas pipes, and the pipe support plate is placed inside the case.  
      The first burner prop and the second burner prop are integrated into one.  
      The case includes a top flange along the top of the plates. The flange is bent downward by approximately five (5) to fifteen (15) degrees.  
      The dual burner grill further includes a burner selector for selecting the first or second burner to operate.  
      The burner selector includes a first valve to the first burner and a second valve to the second burner, and the first valve and the second valve are separate.  
      The dual burner grill further includes a separate lid for covering the burner selector. The burner selector is disposed in the vicinity of the first grill top.  
      The advantages of the present invention are: (1) the dual burner grill is convenient to choose and use one out of two different type of burners; (2) the dual burner grill is easy to discard the waste oil due to the front loading of the waste oil sump; and (3) the dual burner grill enables to dispose two burners in one case by using the space efficiently.  
      Although the present invention is briefly summarized, the fuller understanding of the invention can be obtained by the following drawings, detailed description and appended claims.
