Abstract
A barbecue grill has a grill burner and a cooking grate disposed within a housing with an upper portion pivotally mounted on a lower portion. Means is provided for supporting the housing upper portion in a partial open pivotal position. A smoke incinerator is mounted on the housing upper portion, and has a burner for generating a flame. Smoke is converted to invisible exhaust gases by heating the smoke with the flame. A grill burner locking means is provided, which will prevent unignited fuel from accumulating in the housing in the event that the incinerator burner fails to ignite.
Claims20
A barbecue grill, comprising:
- (a) a cooking unit, the cooking unit including a housing defining a housing chamber, the housing having an upper portion and a lower portion, the cooking unit including a grill burner disposed within the housing, and a cooking grate disposed within the housing and above the grill burner;
- (b) mounting means for mounting the housing upper portion on the housing lower portion;
- and
- (c) a smoke incinerator mounted on the housing upper portion, the smoke incinerator having an incinerator burner for generating a flame, so as to convert smoke to invisible exhaust gases by heating the smoke with the flame.
A barbecue grill, comprising:
- (a) a cooking unit, the cooking unit including a housing defining a housing chamber, the housing having an upper portion and a lower portion, the cooking unit including a grill burner disposed within the housing, and a cooking grate disposed within the housing and above the grill burner;
- (b) a smoke incinerator mounted on the housing upper portion, the smoke incinerator having an incinerator burner for generating a flame, so as to convert smoke to invisible exhaust gases by heating the smoke with the flame, the smoke incinerator having a combustion chamber communicating with the burner, the combustion chamber having a wall, the wall having an inlet opening communicating the combustion chamber with the housing chamber, the inlet opening being juxtaposed with the burner flame so as to create a venturi effect to draw smoke from the housing upper portion, through the inlet opening, and into the combustion chamber, the smoke incinerator having a flue communicating with the combustion chamber, for venting the exhaust gases to the atmosphere;
- (c) a fuel supply;
- (d) a grill burner control connecting the grill burner with the fuel supply, to regulate the flow of fuel to the grill burner;
- (e) an incinerator burner control connecting the incinerator burner with the fuel supply, to regulate the flow of fuel to the incinerator burner;
- (f) a hinge having a pair of hinge elements, including an upper hinge element attached to the housing upper portion, and a lower hinge element attached to the housing lower portion, wherein one hinge element of the pair of hinge elements is juxtaposed opposite one other hinge element of the pair of hinge elements, the hinge having a hinge pin with a longitudinal axis, the hinge pin pivotally connecting the upper hinge element to the lower hinge element for pivotal movement of the housing upper portion from a closed pivotal position to an open pivotal position;
- and
- (g) supporting means for supporting the housing upper portion in a partially open pivotal position wherein the housing chamber is visible and the housing upper portion will collect the smoke.
A method of eliminating smoke from a barbecue grill having a cooking unit, the cooking unit including a housing defining a housing chamber, the housing having an upper portion and a lower portion, the cooking unit including a grill burner disposed within the housing, and a cooking grate disposed within the housing and above the grill burner, the method comprising the steps of:
- (a) mounting a smoke incinerator on the housing upper portion;
- (b) generating a flame with an incinerator burner;
- (c) communicating the burner with a combustion chamber;
- (d) communicating the combustion chamber and the housing chamber with an inlet opening therebetween;
- (e) juxtaposing the inlet opening with the burner flame so as to create a venturi effect;
- (f) drawing smoke from the housing upper portion, through the inlet opening, and into the combustion chamber, by the venturi effect;
- (g) heating the smoke with the flame, within the combustion chamber;
- (h) converting the smoke to invisible exhaust gases with the heating;
- (i) communicating the combustion chamber to atmosphere with a flue;
- and
- (j) venting the exhaust gases to the atmosphere through the flue.
