Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a burner device for a gas water heater of the type in which a plurality of line-shaped gas burners are arranged parallel to each other and housed in a frame casing.

(Prior Art) The applicant has previously developed a device of this type, for example,
As shown in Utility Model Application No. 60-147942 (Utility Model Application No. 62-56923), a generally rectangular line-shaped burner consisting of a burner body and a pair of left and right flanges extending on both sides of the burner body is arranged in the front and rear directions. A burner group consisting of a plurality of parallel burners is inserted into a substantially rectangular frame housing having a pair of left and right side plates through an opening on the lower surface thereof, and is supported by a support member provided on the lower side thereof. ,
Each burner is positioned by being locked from below into a pair of left and right locking grooves formed in the pair of side plates with a pair of left and right locking pieces protruding near the lower ends of both side edges. I proposed the following formula.

(Problem to be solved by the invention) However, in this case, each locking groove is generally prepared in the form of a relatively narrow slit;
In such a device, it is inevitable that the work of inserting and locking each locking piece therein, and therefore the work of inserting and assembling each burner, is relatively troublesome.

(Means for Solving the Problems) The purpose of the present invention is to obtain a device that does not have such inconveniences, that is, a device that makes it easy to insert and assemble each burner. A burner group consisting of a plurality of generally rectangular line-shaped burners, each consisting of a pair of left and right flanges extending outwardly from the burner, arranged in parallel in the front and back direction, has a pair of left and right side plates. A pair of left and right locking pieces that are inserted into a rectangular frame casing through an opening on the lower surface thereof and supported by a support member provided on the lower side, and each burner is protruded from near the lower end of both side edges thereof.
In a type in which positioning is performed by locking from the lower side into a pair of left and right locking grooves formed in the pair of side plates, the locking grooves are positioned relatively at the lower ends thereof. It is wide and enlarged.

(Example) Embodiments of the present invention will be explained with reference to attached drawings.

Figures 1 and 2 show one example.
1 shows a generally rectangular line-shaped burner consisting of a burner body 1a and a pair of left and right flanges 1b, 1b extending on both sides of the burner body 1a. The flame opening 1c is attached to the upper edge of the flame opening 1c and extends longitudinally in the lateral direction.

A burner group is prepared in which a plurality of burners 1 are arranged side by side in the front and back direction, and this burner group is arranged between a pair of left and right side plates 2,
An opening 4 on the lower surface of the substantially rectangular frame casing 3 having a
The burner 1 is inserted through the frame casing 3 and fixed in the frame 3 by being supported by a support member 5 provided on the lower side thereof, and furthermore, each burner 1 is fitted with a pair of left and right locking pieces 6, which protrude near the lower end of both side edges of the burner 1. 6, the pair of side plates 2,
The positioning is performed by being locked in a pair of left and right locking grooves 7, 7 formed in 2.

In the illustrated example, the inside of the frame housing 3 is divided into left and right halves by an intermediate member 8 located at the lower side of the frame, and the burner group described above is divided into one half and the other half. In this case, the intermediate member 8 is provided with the above-mentioned locking grooves 7 on each of its left and right side surfaces 2a, and has an inner side facing each outer side plate 2. The supporting member 5 is configured to act as a side plate, and the supporting member 5 is made up of a lid member provided on the lower surface of the frame casing 1, and the upper surface plate of the frame casing 1 is configured to serve as a burner port opposite to the flame port 1c of each burner 1. 9 and a secondary air port 10 adjacent thereto, the entire structure acts as a flame-holding plate. In the drawing, reference numeral 11 indicates a gas manifold provided below the frame casing 3, and the manifold 11 is provided with each gas nozzle 12 on the lower side facing each burner 1.

Although the above is not particularly different from the conventional one, according to the present invention, the aforementioned locking grooves 7 on each side are enlarged to a relatively wide width at the lower end portions 7a.

To explain this in detail, the locking groove 7 has a vertical slit shape as a whole, and the lower end 7a is connected to the relatively narrow upper end through the intermediate tapered part 7b. I tried to connect it to 7c. Further, in the illustrated example, the side plate 2 has a step portion 2c that slopes upward on the lower edge 2b, and has a shape that bulges outward, and the locking groove 7 is formed on the step portion 2c. It extends above and below the portion 2c. Furthermore, the lower edge 2b
The bulge makes insertion of the burner 1 easier.

Fig. 3 shows a modification example, in which case,
Each side plate 2 is formed with an outwardly bent protrusion at the lower edge 2b, and the locking groove 7 extends over the protrusion at the lower end 7a.

FIG. 4 shows another modification, in which case,
The frame casing 3 is of a type that does not have the above-mentioned flame-holding plate on the upper surface, and the support member 5 is made of a rod inserted into each locking piece 6 in place of the above-mentioned lid member.

(Function) To explain its function, each burner 1 is inserted into the frame casing 3 through the opening 4 on the lower surface and supported by the support member 5, and is engaged with the locking pieces 6 on each side. It is positioned by being locked into the stop groove 7,
During such assembly, the lower end 7a of the locking groove 7 is enlarged to a relatively wide width, so that the locking piece 6 can be inserted through the lower end 7a. The insertion work can be made simple and easy by being guided by the upper end 7c.

(Effect of the invention) According to the invention, each of the locking grooves formed in the side plates on each side is enlarged to a relatively wide width at the lower end, and the engaging piece is attached to the lower end of the locking groove. It can be easily guided from the side, and thus the assembly work of each burner can be made simple and highly efficient, and its structure is simple and can be obtained at low cost.
