Description

[Detailed Description of the Invention] This invention relates to an assembly type gas burner in which a plurality of gas burners are arranged side by side at equal intervals, and is particularly aimed at simplifying the assembly work.

In order to eliminate rattling of the gas burner, a conventional assembly-type gas burner has been proposed in which the gas burner is held between a front plate into which the mixing pipe of the gas burner is fitted and held, and a rear plate having engagement grooves on the top and bottom. (For example, Utility Model Application No. 53-52443) requires work to simultaneously fit the gas burner into the upper and lower engagement grooves of the rear plate, which is extremely difficult and requires a lot of effort. There was a drawback that it was time consuming.

This invention corrects these conventional drawbacks, and will be explained below with reference to the drawings.

In the drawings, A has an opening 2 for the mixing tube 1 approximately in the middle of the front edge, an engagement protrusion 8 on the upper front edge, and engagement protrusions 3 and 4 on the upper rear edge and the rear of the lower edge, respectively. The lower edge front portion of the gas burner A serves as a receiving portion 9.

Reference numeral B denotes a front plate having a plurality of short tube portions 5 arranged in parallel at equal intervals, into which the opening 2 of the mixing tube 1 of the gas burner A can be fitted without play;
Multiple engagement grooves 10 that can be engaged without rattling
are bored at the same interval as the short pipe portion 5, and a mounting seat plate 11 is provided at the lower end for attaching it to the bottom body C, which will be described later. C is front, rear, left and right wall plates 12;
13, 16, 16' are the bottom body fixed to the framework, and the rear wall plate 13 has a plurality of engaging grooves 6, which are the same as the short pipe portions 5, in which the engaging protrusions 4 can be engaged without play. If the receiving part 9 of the gas burner A is placed on the front wall plate 12 and the engaging convex part 4 is fitted into the engaging groove 6 of the rear wall plate 13, the gas burner A will be installed. It is designed to be held substantially horizontally on the bottom body C. Further, D is a rear plate, and on its upper inner surface, a plurality of vertical engagement grooves 7, in which the engagement convex portion 3 can be engaged without play, are provided at the same spacing as the short tube portion 5. A mounting seat plate 14 for attaching this to the bottom body C is provided at the lower end. E and E' are side plates attached to the left and right sides of the bottom body C, and mounting seat plates 17 and 17' are provided at the bottom of the side plates. The front plate B and the rear plate D are fixed by bolts passed through the bottom body C and the mounting seats 11 and 14 by nuts. (The bolt insertion points are shown in Figure 1 a and d, respectively.) Similarly, in this embodiment, the side plates E and E' are tightened and fixed to the bottom body C via the mounting seats 17 and 17'. (The locations are shown in FIG. 1b.) The front parts of the side plates E and E' are fastened to the side ends of the front plate B, and the rear parts are fastened to the side ends of the rear plate D. (The bolt insertion points are shown in Fig. 1 c and e, respectively.) Reference numeral 15 denotes a spring piece bulging into an arc shape to match the installation interval of each gas burner. The gas burners A are individually pressed and held elastically to absorb thermal expansion in the longitudinal direction of the burners. In addition, 18 connects the burner nozzle to the short pipe portion 5.
This is a nozzle tube installed protrudingly with the same spacing as that of the nozzle tube.

In the above configuration, the assembly order will be explained below. First, the front plate B is attached to the front surface of the bottom body C. That is, the mounting seat plate 11 of the front plate B is tightened and fixed to the front wall plate 12 of the bottom body C with bolts, nuts, etc. (the bolt insertion points are shown as a in FIG. 1), and the left and right side plates E, E' are attached to the side wall plates 16, 16' of the bottom body C by the same means (the bolt insertion points are shown in b in Figure 1), and the front parts of the left and right side plates E, E' are attached to both ends of the front plate B. Fix it using the same method. (The bolt insertion points are shown in FIG. 1c.) Here, the front plate B is firmly assembled and connected to the bottom body C as one body via the side plates E and E'.

After that, the gas burner A is connected to the bottom plate C which is connected to the gas burner A.
is placed on the front and rear wall plates 12 and 13, and the engaging protrusion 4 at the rear of the lower edge is fitted into the engaging groove 6 of the rear wall plate 13, and then moved forward to open the opening 2 of the mixing tube 1 at the center of the front edge.
is inserted into the short tube part 5 of the combined front plate B, the engagement convex part 8 on the upper part of the front edge also fits into the engagement groove 10 of the front plate B.
The gas burner is positioned except for the rear upper part. After that, the engagement convex portion 3 on the upper rear edge of the gas burner A is fitted into the vertical engagement groove 7 of the rear plate D, and the mounting seat plate 14 is attached and fixed to the rear wall plate 13 of the bottom plate C with bolts, nuts, etc. (The bolt insertion point is shown as d in Fig. 1.) Then, the gas burner A is positioned so that there is no play in the vertical and horizontal directions, and is pressed and held in the longitudinal direction by the spring pieces 15 to be completely positioned and fixed. . Furthermore, if the rear parts of the side plates E and E' are fixed to the side edges of the rear plate D by the same means (the bolt insertion points are shown at e in Figure 1), the front plate B, the rear plate D, and the bottom body C can be fixed. The assembly becomes strong, and the assembly of the gas burner A is now completed. The nozzle pipe 18 is attached to the front plate B by the same means (the bolt insertion point is indicated by f in FIG. 1).

In the embodiment, the side plates E and E' are fastened to the front plate B, the rear plate D, and the bottom body C using bolts, nuts, etc., but the side plates E and E' do not necessarily have to be used.

As explained above, this idea holds the gas burner by fitting the gas burner into the combined body of the front plate and the bottom body at the top of the leading edge and the mixing pipe, and then attaching the rear plate, which is separate from the bottom body, to the gas burner. Since the structure is such that the engaging convex portion is fitted, there is an advantage that the assembly work can be performed extremely easily and efficiently, and since the gas burners can be individually removed, maintenance and inspection are also convenient. Furthermore, it is an extremely effective assembly type gas burner that is positioned and fixed so that there is no play in the vertical, horizontal, and longitudinal directions.
