Abstract
A gas burner has a gas distribution section, an inlet to the gas distribution section connected to a supply of combustible gas, a plurality of outlets, and a gas diffuser. The gas distribution section includes at least one tubular member having a substantially flat first side and formed into a closed loop-shape. In one embodiment, the burner outlets are slots arranged along the first side and oriented substantially transverse to the axial direction of the tubular members whereby a locally uniform flame front is provided at each outlet. The gas diffuser is disposed adjacent the burner inlet to facilitate a uniform flame front along the entire gas distribution section by smoothing out fluctuations or variations in the incoming gas flow.
Claims21
A burner, comprising:
- a gas distribution section, including at least one tubular member formed into a closed loop shape and having a first side, at least a portion of said first side being flat;
- an inlet to said gas distribution section, said inlet in communication with a supply of combustible gas;
- a plurality of outlets formed into said first side of said gas distribution section;
- a gas diffuser proximate said inlet;
- and
- a blower disposed between said inlet and the supply of combustible gas.
A cooking appliance, comprising:
- a cooking surface;
- and
- a burner disposed beneath said cooking surface, said burner comprising:
- a gas distribution section, including at least one tubular member formed into a closed loop shape and having a first side,
- an inlet to said gas distribution section, said inlet in communication with a supply of combustible gas,
- a plurality of slots formed into said first side of said gas distribution section,
- a gas diffuser proximate said inlet, and
- a blower operatively coupled to said inlet and in communication with the supply of combustible gas.
A burner, comprising:
- a closed loop gas distribution section of generally rectangular shape, including at least one tubular member having a generally rectangular cross-sectional shape and having a substantially flat first side;
- an inlet to said gas distribution section, said inlet in communication with a supply of combustible gas;
- a blower disposed between said inlet and the supply of combustible gas;
- a plurality of slots formed into said first side of said gas distribution section, wherein said slots are arranged to have an orientation which is substantially transverse to an axial direction of said tubular member;
- and
- a gas diffuser disposed within said gas distribution section and proximate said inlet, said diffuser smoothing out any non-uniformities in incoming gas flows at said inlet and providing a uniform distribution of gas to said gas distribution section.
A burner, comprising:
- a gas distribution section, including at least one tubular member formed into a closed loop shape and having a first side;
- an inlet to said gas distribution section, said inlet in communication with a supply of combustible gas;
- a plurality of outlets formed into said first side of said gas distribution section;
- and
- a gas diffuser proximate said inlet;
- wherein said diffuser comprises a plate formed into a shape which defines a bounded volume proximate said inlet, said plate having a plurality of apertures formed therethrough.
A burner for uniformly heating a cooking surface, the burner comprising:
- a gas distribution section, including at least one tubular member formed into a closed loop shape and having a first side, at least a portion of said first side being flat;
- an inlet to said gas distribution section, said inlet in communication with a supply of combustible gas;
- a plurality of outlets formed into said first side of said gas distribution section;
- a gas diffuser proximate said inlet;
- and
- a blower disposed between said inlet and the supply of combustible gas;
- whereby when combustible gas from the supply of combustible gas flows through said burner and is ignited, said burner provides a uniform flame front of short, stable flames for disposition in close proximity to the cooking surface for uniform heating thereof.
A cooking appliance, comprising:
- a cooking surface;
- and
- a burner disposed beneath said cooking surface, said burner comprising:
- a gas distribution section, including at least one tubular member formed into a closed loop shape and having a first side,
- an inlet to said gas distribution section, said inlet in communication with a supply of combustible gas,
- a plurality of slots formed into said first side of said gas distribution section,
- a gas diffuser proximate said inlet, and
- a blower operatively coupled to said inlet and in communication with the supply of combustible gas;
- said first side of said gas distribution section disposed proximate said cooking surface whereby, when combustible gas from the supply of combustible gas flows through said burner and is ignited, said burner provides a uniform flame front of short, stable flames in close proximity to said cooking surface for uniformly heating said cooking surface.
