The present invention ensures that the burner body and the nozzle body constituting the burner in the gas oven are firmly bound, thereby preventing burner defects and preventing burner and nozzle body of the gas oven designed to prevent release during transportation and movement. It's about structure.

In general, a gas oven has a burner on which gas is burned, and the burner includes a nozzle body to which a gas supply pipe is connected and a nozzle is installed, and a burner body and a burner head and a burner that receive gas from the nozzle body. The cap is combined to form a structure.

In addition, the nozzle body has a structure that is fixed to the burner support fixed to the stove body, the burner body is to be installed in a structure that is assembled in a state that is only mounted on the nozzle body.

Therefore, there is a concern that the burner body is separated from the nozzle body by vibration during transportation, and the burner body and the nozzle body are completely in close contact with each other after the installation of the transport even if the burner body is not completely detached from the nozzle body. In some cases, it will be used when it is not fixed.

As described above, when the burner is used in a state where the burner body and the nozzle body are not in close contact with each other, the burner caps of the burner body and the burner head assembled to the burner body are not in the correct position, resulting in unstable combustion or flame abnormality. This is followed by a problem that results in lowered combustion performance.

The present invention has been devised to solve the conventional problems as described above, so that the burner body is bound to the nozzle body fixed to the burner support to prevent assembly defects in advance, while the burner body and the nozzle body are in close contact with each other. The purpose is to improve the combustion performance by being fixed.

In order to achieve the above object, the present invention provides a plurality of binding grooves having insertion grooves and circumferential grooves at equal intervals at the top outer periphery of the standing pipe part of the nozzle body, and at the bottom outer periphery of the venturi pipe part of the burner body. By providing a binding projection to be fitted in the binding groove, the binding protrusion is inserted into the binding groove to be fixed.

And a safety sensor installed in the burner body, while having an elongated protrusion for allowing the binding protrusion to be tightly engaged in the process of allowing the binding protrusion inserted into the binding groove to be inserted laterally. In order to have a directionality for the spark plug to be in place, the width of the binding groove and the binding protrusion are configured differently to be formed in a relative position.

Therefore, the present invention is characterized by having a large and small binding protrusions and binding grooves that can be mutually coupled to the burner and the nozzle body, respectively, and having a constriction protrusion on the upper surface of the circumferential groove of the binding groove. On the basis of the accompanying drawings, preferred embodiments will be described in more detail as follows.

The nozzle body 10 constituting the burner in the gas oven is connected to the primary air inlet 14 through the connection part 11 connected to the gas supply pipe 1 and the nozzle 13 fastened to the nozzle hole 12. The upright pipe part 15 and the burner support 2 to which gas is guided up with the air which flows in are provided with the fixing piece part 16 for fixing the nozzle body 10 to it.

The burner body 20 is provided with a venturi tube 22 which allows gas and primary air to be sucked under the body 21 on which the spark plug 3 and the safety sensor 4 are installed. The nozzle body 10 is configured to be inserted into and connected to the standing pipe part 15.

Therefore, the present invention forms an insertion groove portion 17a which is formed in the vertical direction at the upper periphery of the standing pipe portion 15 of the nozzle body 10, and a circumferential groove portion formed in the circumferential direction from the lower end of the insertion groove portion 17a. A pair of fastening grooves 17 and 17 'including 17b is provided in a relative direction, and the insertion grooves 17a of the fastening grooves 17 and 17' are respectively large and small size (S). It is to achieve (Sa).

In addition, on the upper side of the upper surface of the circumferential groove portion 17b of the binding grooves 17 and 17 ', the contraction protrusions 18 and 18' which protrude slightly are formed.

On the other hand, a pair of binding protrusions 23 and 23 'coupled to the binding grooves 17 and 17' of the nozzle body 10 are opposite to the outer peripheral edge of the venturi tube portion 22 of the burner body 20. Protruding to form, but the binding protrusions 23, 23 'also can be inserted in accordance with the narrow, small size (S) (Sa) of the insertion groove (17a) of the binding grooves (17) (17'). The large size S '(S'a) is achieved.

Referring to the present invention configured as described with reference to Figures 3 and 4 as follows.

The burner body 20 is attached to the nozzle body 20 according to the present invention while the fixing piece 16 is fixed to the burner support 2 by the fixing screw 5.

When the burner body 20 is attached, the binding protrusions 23 and 23 ′ provided at the lower end of the venturi tube portion 22 are inserted into the insertion grooves 17a and 17 'of the nozzle body 10. In this case, the small size (S, S ') (Sa, S'a) is to be inserted between each other.

If, when the binder projection 23 of the wide size (S ') is to be inserted into the insertion groove (17a) of the binding groove (17') of the narrow size (Sa), the binding projection to the insertion groove 17a by the size difference. Since the 23 is not inserted, the nozzle body 10 and the burner body 20 are not bound at all.

Therefore, the present invention is that the nozzle body 10 and the burner body 20 is always coupled with a constant direction, so that the spark plug 3 and the safety sensor 4 is necessarily in the set position.

Therefore, when the same large and narrow sizes S, S '(Sa, S'a) are matched with each other, the binding protrusions 23, 23' are inserted into the insertion grooves 17a of the binding grooves 17, 17 '. After being inserted, the binding projections 23 and 23 'are rotated in the circumferential direction by rotating the burner body 20 so as to be inserted into the circumferential groove 17b. At this time, since the constriction protrusions 18 and 18 'are located on the upper side line side of the circumferential groove 17b, when the binding protrusions 23 and 23' are rotated and inserted, they are inserted tightly and a click sound is heard. Will be.

On the other hand, when the burner body 20 is separated, the burner body 20 is rotated in the insertion groove 17a direction so that the binding protrusions 23, 23 'are separated from the circumferential groove 17b, and then the burner is moved upward. When the body 20 is lifted up, the binding protrusions 23 and 23 'are separated through the insertion groove 17a, thereby being separated.

According to the above description, since the burner body 20 can be fixed to the nozzle body 10 fixed to the burner support 2 by the present invention, there is no flow of the burner body 20. There is no fear of burner body 20 due to vibration during transport.

In addition, the burner body 20 is fixed to the nozzle body 10 at the right position with the directivity, and the assembly is tightly fixed so that combustion performance is improved and assembly failure is not caused. Will be provided.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that the present invention may be modified or changed within the spirit and scope of the present invention, and belongs to the utility model registration claims to which such a change or modification is attached. will be.
