BURNER FOR A GAS BARBECUE GRILL
1. Field of the Invention
The present invention relates to a burner, and more particularly to a burner for a gas barbecue grill and that has a reliable low level heat function and a wide range heat output performance.
2. Description of Related Art
With reference to Fig. 6, a burner (40) for a gas barbecue grill in accordance with the prior art comprises a mixing tube (42) and a side tube (44).
The burner (40) is secured in the housing of the gas barbecue grill and is connected to a gas source with a control valve (50), such that the burner (40) can heat or cook food with a flame from burning gas. The mixing tube (42) is connected with the control valve (50) at one end of the mixing tube (42). The side tube (44) is U-shaped and is connected to the other end of the mixing tube (42) at the middle portion of the side tube (44). The side tube (44) communicates with the mixing tube (42) and has multiple orifices (442) defined in the top ofthe side tube (44). Accordingly, the gas can be led into the side tube (44) through a hose, the control valve (50) and the mixing tube (42) and is emitted from the orifices (442) in the side tube (44). After igniting the gas, flames will occur on the side tube (44) to heat or to cook the food.
In addition, an adjusting knob (52) is mounted on the control valve (40) to adjust the passage in the control valve (50) for the gas passing therethrough so as to control the flames on the burner (40). The user can control the flames to cook the food or keep warm to the food by means of turning the adjusting knob (52). However, when user only wants to keep warm to the food and the user lowers the intensity of the flames, the quantity of gas emitted from the control valve (50) and into the mixing tube (42) is not enough to evenly spread in the mixing tube (42) and the side tube (44) with large diameters. Therefore, the flames on the conventional burner easily go out because that the gas cannot be continuously applied for burning. The gas keeps emitting from the orifices (442) in the side tube (44) when the flames go out, thereby causing an extremely dangerous condition. The conventional burner (40) has not a good performance in a low level heat function, and the use of the conventional burner (40) is not versatile.
The main objective of the invention is to provide a burner for a gas barbecue grill and having a reliable low level heat function and a wide range heat output performance. The burner has a mixing tube, a side tube, an auxiliary tube and a fire bridge. The side tube is secured to one end of the mixing tube and communicates with the mixing tube. Multiple orifices are defined in the top of the side tube. 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 which is connected to the mixing tube. Multiple orifices are defined in the top of the auxiliary tube. Consequently, the gas can be controlled to be led into the mixing tube or the auxiliary tube with the control valve. The fire bridge is connected between the mixing tube and the auxiliary tube. Multiple orifices are defined in the top of the fire bridge. With such a burner, the flames can be switched between the side tube and the auxiliary tube. With a diameter of the auxiliary tube being smaller than that of the mixing tube, the small quantity of gas can evenly spread in the auxiliary tube and the flame on the auxiliary tube will not go out even when the gas pressure is low. Therefore, the burner can provide a reliable low level heat function and a wide range heat output performance 1 THF nRAWTN(.S Fig. 1 is a perspective view of a gas barbecue grill with burners in accordance with the present invention; Fig. 2 is a perspective view of the burner in Fig. 1; Fig. 3 is an operational perspective view of the burner in Fig. 1 showing that a large flame is on the side tube; Fig. 4 is an operational perspective view of the burner in Fig. 1 showing that both side tube and auxiliary tube has flames thereon; Fig. 5 is an operational perspective view of the burner in Fig. 1 showing that a small flame is on the auxiliary tube; and Fig. 6 is a perspective view of a conventional burner in accordance with
the prior art.
With reference to Figs. I and 2, a burner ( 10) for a gas barbecue grill (20) in accordance with the present invention comprises a mixing tube (12) , a side tube ( 14), an auxiliary tube ( 1 6) and a fire bridge ( 18). The burner ( 1 0) is secured in a housing (22) of the barbecue grill (20) for heating or cooking food. The mixing tube (12) is secured in the housing (22) and connected to a control valve (24) at one end of the mixing tube ( 12). Wherein the control valve (24) is connected to a gas source with a hose (not shown), such that the gas can be led into the mixing tube ( 12) through the hose and the control valve (24). The control valve (24) can be a mechanism valve or an electrical valve. An adjusting knob (26) is attached to the control valve (24) to adjust the passage in the control valve (24) communicating with the mixing tube (12). A vent (not numbered) is defined in the mixing tube (12) near the control valve (24), such that the air can enter the mixing tube (12) to mix with the gas for assisting the burning of the gas.
The side tube (14) is U-shaped and is connected to the other end of the mixing tube (12) at a middle portion of the side tube (14). The side tube (14) communicates with the mixing tube (12) and has multiple orifices (142) defined in the top of the side tube (14). Consequently, the gas can be led into the mixing tube (12) and the side tube (14) and is emitted from the orifices (142) in the side tube (14).
The auxiliary tube (16) is mounted above the mixing tube (12) and is connected to the control valve (24), such that the gas can be led into the mixing tube (12) or the auxiliary tube (16) by the control valve (24). The auxiliary tube (16) has a diameter smaller than that of the mixing tube (12). Multiple orifices (162) are defined in the top ofthe auxiliary tube (16). A vent (not numbered) is defined in the auxiliary tube (16) near the control valve (24), such that the air can enter the auxiliary tube (16) to mix with the gas for assisting the burning of the gas.
The fire bridge (18) is communicated between the side tube (14) and the auxiliary tube (16). Multiple orifices (182) are defined in the top of the fire bridge (18).
When the user wants to heat or to cook food, with reference to Fig.3, the user turns the adjusting knob (26) to control a large quantity of gas to be entirely led into the mixing tube (12) with the control valve (24). After igniting, the gas sprayed from the orifices (142) in the side tube (14) will burn and flames will occur on the side tube (14). The flames will be controlled by turning the adjusting knob (26) to adjust the size of the passage in the control valve (24) for the gas passing therethrough.
When the user just wants to keep warm to the food, with reference to Figs. 4 and 5, the adjusting knob (26) is turned to reduce the passage in the control valve (24) communicating to the mixing tube (12) and to open the passage in the control valve (24) communicating to the auxiliary tube ( 16).
Consequently, the gas will be led into the auxiliary tube (16). Before the gas is entirely led into the auxiliary tube, (16) the gas will be simultaneously led into the mixing tube (12) and the auxiliary tube (16) so that the flames on the side tube (14) will keep burning. Therefore, the gas will spread into the fire bridge (18) and is emitted from the orifices (182) in the fire bridge (18). The flame on the side tube ( 14) will ignite the gas emitted from the orifices ( 182) in the fire bridge (18), and flame on the fire bridge (18) will ignite the gas emitted from the orifices (162) in the auxiliary tube (16). Consequently, when the control valve (24)is switched to lead the entire gas into the auxiliary tube ( 16), flames will occur on the auxiliary tube (16) for the user to keep the food warm. Because the diameter ofthe auxiliary tube (16) is smaller than that ofthe mixing tube (12), a small quantity of gas can also evenly spread in the auxiliary tube ( 16). Therefore, the flame on the auxiliary tube ( 16) will not go out even when a small quantity of gas is led into the auxiliary tube (16). An excellent low level warmth effect is provided, this can enlarge of the range of heat output performance of the burner (10). In addition, the safety of using the burner ( l O) is improved.
