Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an ignition mechanism mounting structure for a gas burner in gas combustion equipment such as a gas water heater or a bathtub.

<Prior art> In the ignition mechanism of a gas burner, an ignition plug and a flame rod for ignition detection are inserted and fixed into the burner body in parallel. I have to. As a structure for attaching the ignition mechanism to the side surface, as shown in FIG. Insert the spark plug 06 and flame rod 07 through the gasket 08, and then attach the holding plate 0 from above.
9 and was fixed to the burner body 01 with screws 011.

<Problem to be solved by the invention> In the above gas combustion equipment, the burner body 01 is arranged in a casing (not shown), and therefore the ignition mechanism attached to the side surface 1b of the burner body 01 and the casing There may be cases where sufficient space is not secured between the two. When initially assembling gas combustion equipment, the ignition mechanism is attached to the burner body 1 in advance, and then the casing is attached, so no problems occur during assembly, but spark plugs 06 and flame rods 07 break down after assembly and need to be replaced. When maintaining the ignition mechanism, it may become difficult to operate the screw 011 for fixing the holding plate 09, and in some cases, the casing must be removed, which requires time and effort to maintain the device. There were problems such as.

<Means for Solving the Problems> The present invention has been made in view of the above circumstances, and is a gas burner with a side-mounted ignition mechanism, in which the ignition mechanism can be easily attached and detached from the front. This is to improve maintainability.

Therefore, the present invention adopts the following configuration in an ignition mechanism mounting structure for a gas burner in which a spark plug and a flame rod are inserted and fixed through an opening formed in the side surface of the burner body.

That is, in the present invention, the spark plug and the flame rod are attached and fixed to the mounting plate, and a locking member is provided along the lateral side of the burner body and engages with the tip of the mounting plate to position and fix the same. is provided on the lateral side of the burner body, and a connecting piece connected to the front surface of the burner body by a screw mounted from the front is provided at the rear end of the mounting plate.

<Function> In the above configuration, the spark plug and flame rod are attached and fixed to the mounting plate in advance, and then the spark plug and flame rod are inserted while inserting the mounting plate from the front of the burner body along the side surface of the burner body. Insert diagonally into the opening of the burner body, and after engaging and supporting the tip of the mounting plate with the locking member of the burner body, fix the connecting piece at the rear end of the mounting plate to the burner body by screwing from the front. This completes the installation of the ignition mechanism.

Also, for removal, the above operation can be reversed.

<Example> FIG. 1 is an exploded perspective view of the ignition mechanism mounting structure portion of a gas burner according to the present invention.

The burner body 1 is installed so that its front surface 1a faces outward with respect to a building, and an ignition mechanism 2 is attached to one side surface 1b. A longitudinally long opening 3 for inserting the ignition mechanism is formed in the lateral side surface 1b, and a locking member 4 formed by bending a plate material is screwed to the back side of the opening 3.

As shown in FIG. 2, the ignition mechanism 2 includes a longitudinally long mounting plate 5, a spark plug 6, a flame rod 7,
Consists of a packing 8 and a holding plate 9, and a mounting plate 5
After inserting the spark plug 6 and flame rod 7 into the mounting holes 10 formed at the front and rear of the mounting plate 5 with the gaskets 8 interposed, a retaining plate 9 that covers them from the outside and prevents them from coming off is attached to the mounting plate 5 using screws 11. By being fixed to the ignition mechanism 2, the ignition mechanism 2 can be handled as a single unit.

At the tip of the mounting plate 5, an engagement recess 12 is formed with a widening shape, and by engaging the engagement recess 12 with the free end bent portion 4a of the locking member 4 from the front, The tip of the mounting plate 5 is prevented from moving up and down and from rising from the side surface 1b of the burner body. In addition, between the side surface 1b and the ignition mechanism 2,
Another seal 13 is interposed. Also, the mounting plate 5
At the rear end, a connecting piece 5a is formed which is bent toward the front side of the burner body 1, and by abutting the connecting piece 5a against the front side of the burner body 1 and tightening the screw 14 from the front, the mounting plate is attached. The rear end of 5 is fixed.

Since the ignition mechanism mounting structure of the present invention is constructed as described above, the packing 13 is attached to the unitized ignition mechanism 2, and then the ignition mechanism 2 is attached to the burner main body as shown in FIG. The spark plug 6 and flame rod 7 are inserted from the front along the side surface 1b while being inclined with respect to the side surface 1b, and the tips of the spark plug 6 and flame rod 7 are inserted into the burner body 1 through the opening 3. Then, after positioning and engaging the tip of the mounting plate 5 with the locking member 4 and aligning the entire mounting plate 5 with the burner body 1, the connecting piece 5a is fixed to the front of the burner body 1 with the screw 14 to complete the installation. do.

The ignition mechanism 2 can be removed by performing the above operation in reverse order.

<Effects of the invention> According to the invention, although the ignition mechanism is attached to the side surface of the burner body, it can be installed and removed from the front of the burner body, and the ignition mechanism can be attached to the burner body and casing of gas combustion equipment. Even if there is not much space between the side ignition mechanism and the side ignition mechanism, maintenance of the side ignition mechanism can be performed easily and easily. In particular, in the case of the ignition mechanism, the mounting plate is treated as a unit with the spark plug and flame rod assembled and set in advance. Parts will not come off from the burner body,
It has excellent handling properties.
