Combustion assembly with improved structure

Abstract

The invention relates to a combustion assembly with an improved structure. The combustion assembly comprises a gas dividing disc, an outer ring burner cap and an inner ring burner cap, wherein the gasdividing disc comprises a round hub part, a cone-shaped guide part is formed on the outer wall of the hub part; a plurality of fan-shaped air inlet holes penetrating through the bottom surface of theguide disc are formed in the top surface of the guide disc; a countersink is formed in the bottom surface of the hub part; a round boss is formed in the bottom surface of the countersink; a step holepenetrating through the top surface of the hub part is formed in the boss; a gas dividing slot which is obliquely formed is formed in the guide disc between adjacent air inlet holes; one end of the gas dividing slot penetrates through the outer wall of the guide disc while the other end communicates to the countersink in the hub part; and a seal ring extending downward and communicating to the countersink is formed in the bottom surface of the hub part. The gas dividing disc is casted integrally, and a corresponding structure is additionally arranged, so that the combustion assembly is hermetically connected to a furnace head to achieve effective sealing; the combustion assembly is convenient to detach and neaten and clean the cooking stove board in daily life.

Description

Technical field: [0001] The invention relates to the technical field of gas stoves, and more specifically relates to a combustion assembly with improved structure. Background technique: [0002] Gas stoves refer to kitchen utensils that are heated directly by gaseous fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas. It mainly consists of a burner (burner head, inner and outer fire cover), valve body, etc. At present, the existing burners are composed of a burner head, a gas distribution plate and an inner and outer ring fire cover. The existing gas distribution plate and the burner head It adopts radial or end face fit, and relies on screw locking to ensure airtightness. This kind of processing method and matching method cannot meet the needs of users for easy cleaning and disassembly. Moreover, since the processing of the end face requires very high precision, once there are some foreign objects or casting defects on the end face, it will le...

Problems solved by technology

This kind of processing method and matching method cannot meet the needs of users for easy cleaning and easy disassembly

And because the processing of the end face requires very high precision, once there is a little foreign matter or casting defect on the end face, it will lead to poor sealing and air leakage

Moreover, most of the existing burner head and gas distribution plate adopt a screw locking structure, and the user cannot disassemble it normally during the daily maintenance and cleaning of the stove top; the gas distribution plate of the existing burner needs to use an upper cover and a base Divide the die-casting process, and divide it into two separate parts for die-casting; this process has the risk of leakage at the fit, and requires very high machining accuracy
