CONSTITUTION:A combustion plate 3 is provided at an outer periphery with a gas seal member 4 and is contained in a burner body 1 and supported to a plate holder 5. The combustion plate is securely nipped between the burner body 1 and a burner securing plate 6. An electrode 7 is positioned between the combustion plate 3 and the burner body 1, the one end thereof is extended through a through-hole 8 of the combustion plate 3, and the other end has a flange part 9 larger than the through-hole. A leaf spring 10 is located between the burner body 1 and a space, and is securely and forcedly adhered to the combustion plate 3. An ignition electrode 11 is disposed to the electrode 7 extended through the combustion plate 3, and through spark discharge, combustion air-fuel mixture injected against a combustion plate 3 surface is ignited and fired for combustion. This constitution prevents the occurrence of defective ignition.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a burner device for combustion equipment used in general households. BACKGROUND OF THE INVENTION In a conventional burner device having multiple flame holes, the ignition means is provided on the front side of the combustion plate, as in the burner device shown in FIG. 3, for example. negative! As shown in Fig. 4, discharge ignition is performed by a burner device in which a protrusion connected from the burner body serves as a negative pole. Furthermore, in the case of a burner device (not shown) in which the combustion plate is horizontally placed with a ceramic oven plate, it is known that the burner device is ignited by an ignition flame by resetting the ignition device.

I18 to be Solved by the Invention However, in the conventional burner device described above, the cost is high if the positive and negative electrodes are made to face, and when the negative electrode is made to face from the burner body, the negative electrode part partially covers the combustion plate. At the same time, it is exposed to high-temperature combustion exhaust gas,
Ignition failure occurs due to incomplete combustion and thermal deterioration of the negative electrode.
Ignition using a pilot flame found in burner devices using ceramic plates requires an ignition device and a gas control device to form the pilot flame, making it significantly more expensive than directly igniting the burner by electric discharge. Means for Solving the Problems In order to solve the above-mentioned problems, the burner device of the present invention has a structure including an ignition negative electrode that penetrates the combustion plate, has its other end pressed against the burner body, and has its other end exposed to the surface of the combustion plate. At the same time, the hole in the combustion plate through which the negative electrode for ignition passes is used as the flame hole in the combustion plate. Effect: Due to the above structure, the burner device of the present invention makes it possible to provide a negative electrode for ignition in the combustion plate, which simplifies the ignition process, and in the case of a ceramic plate, the combustion plate is an electrical insulator. Even if there is, it becomes possible to easily place the negative electrode for ignition.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. As shown in FIG. 1, the combustion plate 3 is housed in the burner body 1 with a gas seal member 4 applied to its outer periphery, supported by a plate holder 5, and fixed by being sandwiched between the burner body 1 and the burner fixing plate 6 by tightening them. It will be done. FIG. 2 shows details of the vicinity of the ignition electrode (hereinafter referred to as electrode) 7. The electrode 7 is located between the combustion plate 3 and the burner body 1, one end passes through the through hole 8 of the combustion plate 3, and the other end A flange portion 9 larger than the through hole is formed, a leaf spring 10 is interposed in the space between the burner body 1, and the combustion plate 3 is crimped and fixed.

By disposing an ignition electrode 11 on the electrode 7 that penetrates the combustion plate 3 and causing a spark discharge, the combustion mixture ejected onto the surface of the combustion plate 3 is ignited, ignited, and combusted. The electrode 7 does not cover the combustion plate 3, and by using a heat-resistant material only for the electrode 7, ignition failure due to deterioration can be prevented. Further, even if the combustion plate 3 is made of an insulator such as ceramic, a negative station can be easily provided and the combustion plate 3
By using the flame hole 8', it is possible to set it at any position regardless of the combustion plate 3.

Effects of the Invention As is clear from the description of the embodiments above, the burner installation of the present invention has the following effects. (1) By providing a simple discharge part on the surface of the combustion plate, it is possible to minimize deterioration due to heating without affecting combustion, and to obtain more reliable ignition. (2) Even if the combustion plate is an insulator, a negative electrode for spark discharge can be easily provided, making it possible to ignite the burner at low cost. (3) Since the flame hole of the combustion plate is a through hole (i!! hole), it is possible to position the negative electrode regardless of the combustion plate, which facilitates the processing of the combustion plate and enables common use. ．．
