Ignition or kindling device coaxial with furnace end combustion chamber

Abstract

The invention relates to the technical field of commercial gas stove fittings, in particular to an ignition or kindling device coaxial with a furnace end combustion chamber. The ignition or kindling device comprises a kindling tube, a kindling head, an umbrella cover, an umbrella cover pillar, an ignition needle, a gas transmission tee and locking nuts. By adopting the ignition or kindling deviceprovided by the invention, as the diameter of the umbrella cover is larger than the diameter of the kindling head, oil-water sundries which fall down in the use process of a furnace end can be thoroughly sheltered from falling into the kindling head, damages caused on baffle plate fire holes, an ignition needle and a ceramic can be thoroughly avoided, benefits can be brought to a kindling functionand the use stability of the ignition needle and prolonging of the service life; and meanwhile, the kindling tube is coaxial with the ignition needle, the circumference of a cavity in a mixed gas chamber can be guaranteed to be consistent, so that gas circulation of a premixed gas chamber can be avoided from generating resistance change, the benefit is bought to promotion of the uniformity of thecombustion energy and a flame of the furnace end, the adverse effect of the oil-water sundries to the kindling and the ignition needle can be effectively prevented, and the adverse effect on the uniformities of an air pressure and a flow rate caused when the furnace end organizes gas to combust can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of commercial gas appliance accessories, in particular to an ignition and kindling device coaxial with a burner combustion chamber. Background technique [0002] At present, the structure of the ignition needle and the kindling of the commercial gas burner is roughly divided into two types: the internal installation of the stove and the external installation. Among them, the ignition needle and the kindling device installed inside the stove are all installed side by side, and the ignition needle and the kindling are both independent. The structure, one left and one right are respectively placed inside the combustion chamber of the burner head. In order to ensure that the ignition gas is evenly distributed in the combustion chamber after flowing out, the head of the fire structure will be placed in the center of the burner combustion chamber, and the ignition needle will be placed in the ignition head.

[0002] At present, the structure of the ignition needle and the kindling of the commercial gas burner is roughly divided into two types: the internal installation of the stove and the external installation. Among them, the ignition needle and the kindling device installed inside the stove are all installed side by side, and the ignition needle and the kindling are both independent. The structure, one left and one right are respectively placed inside the combustion chamber of the burner head. In order to ensure that the ignition gas is evenly distributed in the combustion chamber after flowing out, the head of the fire structure will be placed in the center of the burner combustion chamber, and the ignition needle will be placed in the ignition head. The external periphery is located off the center, and the disadvantage of the above-mentioned structural features is that the ignition needle is placed on the side of the ignition head, and the canopy on the top of the ignition head cannot cover the ignition needle coaxially, so that the ignition needle can only be exposed in a relatively open area. In the combustion chamber, the oil and water debris dropped by the chef when cooking will directly fall on the ignition needle, so it is very easy to cause short circuit of the electrode of the ignition needle, and damage to the ignition needle magnet due to rapid cooling and rapid heating; at the same time, the ignition needle is placed on the fire The structure of the side of the head, the part where the ignition needle and the fire seed are located in the mixed gas chamber of the burner will change the gas channel in the mixed gas chamber and the consistency of the positions of each point in the axial direction, and it is very easy to change the resistance of the gas flow in it. , resulting in uneven distribution of gas pressure or flow, which in turn affects the balance of the combustion flame and heat of the burner head, and has a negative impact on the improvement of the overall quality of the burner head
