Description
Technical Field
The invention relates to a burner fire cover.
Background
All combustors on the existing market are central fire, outer ring fire split type structure, the structure of design like this mainly is that the required secondary air of central fire burning needs to supplement through the clearance between central fire lid and the outer ring fire lid, and this structure must cause the combustor diameter grow to make combustor power big more, and the diameter of fire lid and combustor is big more, and its efficiency just is difficult to improve more. Therefore, the power of the combustor on the current market is generally about 3.8kW to 4.2 kW.
And the flame of the central fire cover of the existing burner extends outwards for burning, so that the center of the pot bottom is in a heating state without open fire, the energy efficiency is difficult to improve, and the central fire cover is not suitable for the cooking requirement of a small-bottom pot. In the prior art, although some burners are provided with the fire holes of the burners in the central fire inner ring, the combustion power is generally very low due to the structure, and the effect on improving the energy efficiency and the actual use requirement is very small.
Especially 100 diameter high feet and 120 diameter high feet on the existing market, in order to provide secondary air to central fire, it is inside intercommunication with the gas-cooker drain pan to provide secondary air to the furnace end by the combustor bottom between central fire lid and the outer loop fire lid, firstly secondary air can not effectively provide when the cupboard seals, secondly the hot water that produces easily directly flows into the cooking utensils inside its use, easily corrodes and corrodes gas-cooker internal fittings, has very big influence to gas-cooker's life.
In summary, with the improvement of energy saving and environmental protection requirements and the improvement of the consumption level of people, how to solve the problems of design, processing, manufacturing and the like of the furnace end by using a new process and a new structure is a major problem in the industry at present, and the design and creation of a new technology is also a development trend of the industry and the country.
