Charcoal roaster

Abstract

A. charcoal roaster has a stand having a top and an ash bin, a bottommost layer detachably mounted on the top of the stand, at least one containing layer detachably mounted on the bottommost layer and a grill assembly detachably mounted on the at least one containing layer. The bottommost layer and the at least one containing layer individually have multiple ventilating holes so fresh air is drawn into each layer to make charcoal burn efficiently without having to be stirred even when charcoal is stacked thickly. Each containing layer and the bottommost layer directs fresh air into deep places inside the charcoal roaster. Moreover, by adding or removing containing layers, the quantity of charcoal is adjustable.

1 . A charcoal roaster comprising: 
 a stand ( 10 ) having 
 a top; and  
 an ash bin ( 12 ) mounted in the stand ( 10 ) near the top;  
   a bottommost layer ( 20 ) mounted on the top of the stand ( 10 ), being a shallow bowl and having 
 a bottom ( 22 );  
 a grating ( 222 ) formed on the bottom ( 22 ); and  
 an upper inclined wall ( 24 ) extending inward and having multiple ventilating holes ( 242 );  
   at least one containing layer ( 30 ) mounted concentrically on the bottommost layer ( 20 ), and each one of the at least one containing layer ( 30 ) being an annular ring and having an upper inclined wall ( 32 ) and a lower inclined wall ( 34 ), both walls extending inward, wherein the at least one containing layer ( 30 ) individually has multiple ventilating holes ( 322 ) defined in the upper inclined wall ( 32 ) of the at least one containing layer ( 30 ); and    a grill assembly ( 40 ) detachably mounted on the at least one containing layer ( 30 ).    
   
   
       2 . The charcoal roaster as claimed in  claim 1 , wherein the charcoal roaster has at least two containing layers ( 30 ) and each one of the at least two containing layers ( 30 ) is larger than an adjacent one below; 
 the upper inclined wall ( 32 ) extends inward and upward and has a top opening and a diameter defined at the top opening;    the lower inclined wall ( 34 ) extends inward and downward and has a bottom opening and a diameter defined at the bottom opening;    wherein, the diameter of the lower inclined wall ( 34 ) is smaller than the diameter of the upper inclined wall ( 32 ) on an adjacent containing layer ( 30 ) below so that part of the lower inclined wall ( 34 ) of each containing layer ( 30 ) extends into an inner space within the adjacent containing layer ( 30 ) below to guide air between two adjacent containing layers ( 30 ).    
   
   
       3 . The charcoal roaster as claimed in  claim 1 , wherein the stand ( 10 ) has 
 a pedestal ( 102 ); and    a conical body ( 104 ) mounted on the pedestal ( 102 ) and having an open top and multiple ventilating holes ( 106 ) defined through the conical body ( 104 ).    
   
   
       4 . The charcoal roaster as claimed in  claim 2 , wherein the stand ( 10 ) has 
 a pedestal ( 102 ); and    a conical body ( 104 ) mounted on the pedestal ( 102 ) and having an open top and multiple ventilating holes ( 106 ) defined through the conical body ( 104 ).    
   
   
       5 . The charcoal roaster as claimed in  claim 4 , wherein the grill assembly ( 40 ) comprises: 
 a base ( 41 ) having a lower inclined wall extending into a topmost one of the at least one containing layer ( 30 );    a grill ( 42 ) detachably mounted on the base ( 41 ) and having a handle; and    a cover ( 44 ) detachably mounted on the grill ( 42 ).
