A lateral burner includes a case attached to a wall of a barbecue stove and connected to a pipe of the barbecue stove. A conduit is attached to the case for sending gas therein from the pipe and made with apertures through which the gas is sent. A heat-transferring plate is placed before the conduit and made with apertures through which the gas is sent. A ceramic plate is placed before the heat-transferring plate for protection against wind. The ceramic plate defines apertures through which the gas is sent. An igniter is placed before the ceramic plate for igniting the gas sent through the apertures of the ceramic plate. A front fender is placed before the igniter for protection against wind.

Description

BACKGROUND OF INVENTION

1. Field of Invention
The present invention relates to a burner of a barbecue stove and, more particularly, to a barbecue stove including an underside burner for roasting food from the bottom and a lateral burner for roasting the food from the back.
2. Related Prior Art
A barbecue party is an activity in which many people can take part and enjoy themselves. People are having barbecue parties not only for food but also for fun. A barbecue stove is the most important utility in a barbecue party. There are various barbecue stoves ranging from simple disposable barbecue grids to complicated movable barbecue stoves. Many types of food can be barbecued. Meat, corn and seafood are popular among other things.
To roast a large chunk of food such as a large chunk of beef, an entire piglet and an entire chicken, there is devised a barbecue stove including a burner and a skewer. The skewer is inserted through the large chunk of food and placed above the burner. The burner heats the food from the bottom. To have the large chunk of food evenly roasted, the skewer is rotated. However, it is exhausting to keep the skewer rotated. Hence, it is not surprising that food is often not evenly roasted by a barbecue stove including only one burner.
To overcome the above-mentioned problem with the barbecue stove including only one burner, there is an attempt to provide a barbecue stove including an underside burner for heating food from the bottom and a lateral burner for heating the food from the back. However, the blaze generated by the lateral burner is often put out by strong wind. This might entail uneven roasting of the food and might even cause danger to users. Hence, the attempt is so far not successful.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.

SUMMARY OF INVENTION

It is the primary objective of the present invention to provide a barbecue stove with an underside burner and a lateral burner that is stably operable against wind.
According to the present invention, a lateral burner includes a case attached to a wall of a barbecue stove and connected to a pipe of the barbecue stove. A conduit is attached to the case for sending gas therein from the pipe and made with apertures through which the gas is sent. A heat-transferring plate is placed before the conduit and made with apertures through which the gas is sent. A ceramic plate is placed before the heat-transferring plate for protection against wind. The ceramic plate defines apertures through which the gas is sent. An igniter is placed before the ceramic plate for igniting the gas sent through the apertures of the ceramic plate. A front fender is placed before the igniter for protection against wind.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to FIG. 5, there is shown a barbecue stove equipped with a lateral burner according to the preferred embodiment of the present invention. The barbecue stove includes an underside burner 55 for burning food from the bottom and a lateral burner 57 for heating food from the back. The barbecue stove includes a wall 50 extended around the underside burner 55. The wall 50 includes a rear portion 56 for supporting the lateral burner 57.
Referring to FIGS. 1 through 4, the lateral burner 57 includes a case 10, a conduit 15, a heat-transferring plate 18, a ceramic plate 35, a frame 30, an igniter 31, a rear fender 12 and a front fender 32.
The case 10 is open in the front and includes a first lateral wall 21 and a second lateral wall 22 opposite to the first lateral wall 21. The back of the case 10 is attached to the rear portion 56 of the wall 50.
A pipe 20 includes a first end connected to a gas source and a second end connected to the first lateral wall 21 of the case 10 by a connector 11.
The conduit 15 is placed in the case 10. The conduit 15 defines a plurality of apertures 16. The conduit 15 is placed in the case 10 by a mount 13. The conduit 15 includes a first end in communication with the second end of the pipe 20 and a second end to which a net 17 is attached. Gas is sent to the conduit 15 from the pipe 20. A major portion of the gas is sent from the conduit 15 through the apertures 16. A minor portion of the gas is released, from the conduit 15 through the net 17 so that the minor portion of the gas is spread in a portion of the case 10 near the second lateral wall 22.
The heat-transferring plate 18 is placed in the case 10. The heat-transferring plate 18 defines a series of apertures 19 near and along a lower edge thereof and another series of apertures 19 near and along a lateral edge thereof. The heat-transferring plate 18 is placed between the conduit 15 and the ceramic plate 35.
The ceramic plate 35 is placed in the case 10. The ceramic plate 35 defines a plurality of apertures 36. The ceramic plate 35 is attached to the case 10 by the frame 30. The major portion of the gas is sent through the apertures 36 of the ceramic plate 35. The minor portion of the gas is also sent through the apertures 36 of the ceramic plate 35.
The frame 30 is used to keep the conduit 15, the heat-transferring plate 18 and the ceramic plate 35 in the case 10. More particularly, the ceramic plate 35 is framed by the frame 30.
The igniter 31 is attached to the case 10 in the vicinity of the second lateral wall 22 and in front of the ceramic plate 35.
Referring to FIG. 3, the minor portion of the gas is ignited by the igniter 31 when the igniter 31 is actuated by turning a switch or knob. Hence, a primary blaze is generated.
Referring to FIG. 4, the major portion of the gas is burnt by the original blaze so that a secondary blaze is generated. The secondary blaze remains when the primary blaze stops as the igniter 31 is turned off by releasing the switch.
The rear fender 12 is attached to the case 10 in the vicinity of the first lateral wall 21.
The front fender 32 is attached to the case 10 near the second lateral wall 22 and before the igniter 31. The front fender 32 protects the igniter 31 against wind so that the primary blaze can smoothly be generated. The ceramic plate 35 protects the heat-transferring plate 18 against wind so that the secondary blaze can be retained. The ceramic plate 35 however allows the transfer of heat and the gas. Should the secondary blaze be put out by strong wind, another primary blaze could easily be generated so that another secondary blaze could be generated.
Equipped with the underside burner 55 and the lateral burner 57, the barbecue stove roasts the food from the bottom and from the back. It is hence easier to evenly roast the food with the barbecue stove according to the present invention than with a barbecue stove equipped with only an underside burner.
The present invention has been described through the illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
