BURNER AND COOKING APPLIANCE THEREWITH BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burner and a cooking appliance having the same, and more particularly, to a burner and a cooking appliance having the burner, which are provided to provide heat for heating a food in a cooking chamber such as an oven.

A cooking device is one of household appliances for cooking food, and is installed in a kitchen space to cook food according to a user's intention. Such cooking devices can be classified into various types according to the heat source or type used and the type of fuel.

Cooking equipment can be classified into open type and closed type cooking equipment depending on the type of space where food is placed. The closed cooking devices include an oven and a microwave oven, and open cooking devices include a cooktop and a hop.

A closed type cooking device is a cooking device that shields a space where food is placed and cooks food by heating a shielded space. The closed type cooking apparatus is provided with a cooking chamber, which is a space that is shielded when the food is placed and food is to be cooked. Such a cooking chamber becomes a space where food is substantially cooked. In the interior or exterior space of the cooking chamber, a heat source is provided to heat the cooking chamber.

The closed cooking device may be classified into a gas oven and an electric oven depending on the type of the heat source.

Among these closed-type cooking apparatuses, the gas oven is a cooking apparatus having a heat source for burning a mixed gas. The gas oven is provided with a plurality of burners for cooking food in the cooking chamber. For example, a gas oven is provided with a broil burner provided at an upper portion of a cooking chamber, a bake burner provided at a lower portion of the cooking chamber, and the like.

Each of the burners is provided with a salt hole through which the mixed gas supplied into the burner is discharged. The gas mixture discharged from the flue gas is ignited by the ignition device to form a flame, and the gas oven can cook the food by heating the food inside the cooking chamber using the flame generated in this manner.

The blower burner is installed to heat the food inside the cooking chamber at an upper portion of the cooking chamber. Such a broiler burner includes a burner body formed with a salt hole to generate a flame, a nozzle for supplying a gas to be burned in the burner body, and a mixed gas formed by mixing gas supplied from the nozzle with air, A mixing tube, and a reflector installed on an upper portion of the burner main body to reflect and reflect flames and heat generated from the burner main body.

An air shutter is provided at an inlet side of the mixing tube connected to the nozzle to form a passage for introducing air into the mixing tube. The nozzle is installed at an inlet side of the mixing tube provided with the air shutter.

The nozzle is fixed to the inside of the cooking chamber by being coupled with a nozzle holder fixed to the inside of the cooking chamber and is connected to the inlet of the mixing tube so that the spray hole for injecting gas from the nozzle is coupled to the inside of the mixing tube. .

The gas injected from the nozzles thus installed flows into the mixing tube through the portion provided with the air shutter and the air introduced through the air shutter is sucked into the mixing tube along with the gas flowing into the mixing tube, Lt; / RTI > In this way, a gas mixture of gas and air is supplied to the burner body, and the mixture gas is ejected through the air holes to burn the burner.

At this time, in order for the burner to be completely burned, the air must be sufficiently supplied. In order to sufficiently supply the air, it is very important that the alignment of the nozzles is highly accurate.

That is, in order to completely burn the burner, the nozzles must be aligned so that the gas injection direction of the nozzles is accurately directed to the inlet of the mixing chamber. If such nozzles are not properly aligned, the amount of air sucked along with the gas is reduced, The air is not sufficiently supplied to the inside.

If the supply of air to the mixing chamber is not sufficiently performed, the burner is not completely burned. As a result, the thermal efficiency of the burner is lowered and the amount of generated gas such as carbon monoxide is increased.

It is a matter of course that the jet flow path inside the nozzle 130 and the mixing tube flow path 121 inside the mixing tube 120 are located on a straight line.

The nozzles 130 aligned in this way can be fixedly coupled to the mixing tube 120 through engagement with the fixture 150 fixedly coupled to the mixing tube 120.

That is, the nozzle 130 is fixedly coupled to the mixing tube 120 via the fixing body 150, so that the nozzle 130 is not moved relative to the mixing tube 120, Even if the installation state of the burner main body 110 to which the mixing tube 120 is connected or the installation state of the nozzle holder 140 to which the nozzle 130 is connected is changed, it is possible to maintain the stable state on the mixing tube 120 So that the correct alignment of the nozzle 130 can be maintained unchanged.

The gas injected through the nozzle 130 can be supplied to the inlet of the mixing tube 120 (as shown in FIG. 7) 122 to be accurately directed and supplied to the mixing tube channel 121 inside the mixing tube 120. [

Since the gas flowing into the mixing tube channel 121 can pass through the mixing tube channel 121 while minimizing the collision with the inner wall of the mixing tube 120 in which the mixing tube channel 121 is formed, 122 can be efficiently increased.

A sufficient pressure drop is formed around the inlet 122 and the mixing tube 120 so that air can be smoothly introduced into the mixing tube 121 through the inlet 122. As a result, 121 can be supplied with a sufficient amount of air.

According to the burner 100 and the cooking apparatus having the burner 100 of the present embodiment as described above, the nozzle 130 can be positioned and fixed by using the fixture 150 installed between the mixing tube 120 and the nozzle 130. [ So that the alignment of the nozzles 130 can be performed with high accuracy so that a sufficient amount of air can be supplied to the mixing tube channel 121 and the effect that the complete burning of the burner can be effected effectively .

According to the burner 100 of the present embodiment and the cooking apparatus having the same, it is possible to stably maintain the state where the nozzle 130 aligned in the fixed position is fixedly coupled to the mixing tube 120, Even if the state of the burner main body 110 to which the nozzle 130 is connected or the state of the nozzle holder 140 to which the nozzle 130 is connected is changed, the nozzle 130 can be stably positioned.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
