  • Patent number: 6622715
    Abstract: A barbecue has a hollow body with a front wall, a rear wall, two sidewalls and a bottom. The body has a pair of support edges formed at a top thereof and a first cooking grill placed on the support edges. A U-like seat is provided in the body and has two opposite ends secured to the body and two opposite sidewalls spaced apart from the body. Two pairs of steps are formed at the sidewalls of the seat, wherein the first pair of steps is below the second pair of steps. A charcoal grill is placed on the first pair of steps, and a second cooking grill is placed on the second pair of steps. Whereby, the heat generated by burning charcoal does not directly transmit to the body spaced apart from the seat, and the body will not be prematurely corroded and has a long use life.

  • Patent number: 6553986
    Abstract: A burner has a mixing tube, a side tube, an auxiliary tube and a fire bridge. The auxiliary tube with a diameter smaller than that of the mixing tube is mounted above the mixing tube and is connected to the control valve connected to the mixing tube. Multiple orifices are defined in the top of the auxiliary tube. The fire bridge is connected between the mixing tube and the auxiliary. Multiple orifices are defined in the top of the fire bridge. Accordingly, the flames can be switched between the side tube and the auxiliary tube. With a diameter of the auxiliary tube being small relative to the mixing tube, the flame on the auxiliary tube will not go out even when a small quantity of gas is led into the auxiliary tube. Consequently, the burner can provide a reliable low level heat function.
