Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the configuration of a pilot burner that can be applied to various gas types, and aims to make it possible to handle any gas type with a single touch.

There is no conventional pilot burner that can be used universally for all types of gas, and it is necessary to change the diameter of the pilot burner nozzle depending on the type of gas.
It was necessary to adjust the opening degree of the damper, and it took time and effort to remove and adjust screws for each part. In addition, the combustion state of the pilot burner itself differs depending on the type of gas, and the time for flame transfer between flame holes also varies, resulting in many problems such as performance issues, difficulty in adjustment work, and parts cost. It was hot.

The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the drawings.

In Fig. 1, 1 is the pilot burner body, 2
is an ignition plug, which is designed to ignite by discharging electricity between it and an electrode 3 protruding from the flame hole of the pilot burner. Reference numeral 4 denotes a flame transfer hole, in front of which a standing plate 5 is provided at right angles to the jetting direction of the pilot nozzle, and auxiliary flame holes 6 are provided on both sides of the flame transfer hole. Further, on the opposite side of the pilot burner from the spark plug, there is an element flame hole 7 and a thermocouple element 8 facing adjacent thereto. 9 is a base plate to which each of the above-mentioned parts is attached. A primary air conditioner 14 is provided with a primary air port 10 on the gas inlet side of the pilot burner 1 and slits 11 on both sides, and further has a primary air port 12 corresponding to each gas type and a slit 13 corresponding to the slit. and a pilot nozzle 16 having slits 15 corresponding to the slits are fitted together and fixed by inserting a pin 17 into the three slits. FIG. 2 shows a sectional view of the pilot nozzle 16 in a fitted state. Reference numeral 18 denotes an end face of the pilot burner, which fits into a notch 19 of the primary air regulator 14 to stop rotation.

In the above configuration, the gas ejected from the pilot nozzle 16 obtains primary air through the primary air holes 12 of the primary air regulator 14, becomes a mixed gas, and reaches each flame hole. It is discharged and ignited between the electrode 3 and the spark plug 2, and the interaction between the auxiliary flame hole 6, the flame transfer flame hole 4, and the standing plate 5 reliably ignites the element flame hole 7 and heats the thermocouple element 18. It becomes like this. The primary air port 10 of the pilot burner 1 is preset to the largest fire diameter among all gases, and primary air ports 12 of different diameters are provided on the front and back of the primary air regulator 14 for each gas type. There is, and the primary air is adjusted by this diameter. Pilot burner 1, primary air regulator 14, pilot nozzle 16
The pin 17 is fixed with one touch, and is particularly easy to attach and detach.

As described above, according to the present invention, the following effects can be obtained.

(1) Pilot burner 1, primary air regulator 14,
The pilot nozzle 16 and pin 17 are fixed in a one-touch manner, and are detachable and easy to attach, making gas calorie conversion, repair, and adjustment easy.

(2) The parts cost is extremely low because three parts are fixed at the same time using inexpensive pins.

(3) Since the primary air regulator 14 discharges the mixed gas with the amount of primary air appropriately adjusted, the ignition rate is high and production costs can be reduced without the need for conventional pilot burners for air purge. did it.

(4) Any gas can instantly ignite from the electrode 3 to the element flame hole 7, and the flame stability is excellent even in windy conditions. by standing plate 5 and a suitable gas mixture).

(5) Spark plug on one side for pilot burner,
By providing a thermocouple element on the other side and by using the one-touch assembly method described above, the overall height of the parts can be kept low, and a compact pilot burner device with high performance can be provided.

(6) Gas conversion can be performed simply by removing the pin, making it convenient to attach and detach by hand without tools, even in tight spaces inside gas appliances.
