Description

Be used in the infrared metal honeycomb burner on the gas appliance

Technical field:

The utility model relates to the gas appliance technical field, refers in particular to a kind of infrared metal honeycomb burner that is used on the gas appliance (natural gas, oil liquefied gas, artificial coal gas, biogas).

Background technology:

As everyone knows, existing by the auxiliary air aftercombustion, the atmospheric gas kitchen range of Convective Heating exist that the thermal efficiency is low, incomplete combustion, NXO compound and the higher many defectives of CO content discharging, people are in order to improve the thermal efficiency of kitchen range in recent years, reduce discharge of harmful gases and to the pollution of environment, and utility model has been created the gas kitchen ranges of fully premixed infrared radiation heating.The gas kitchen ranges that facts have proved fully premixed flameless combustion infrared radiation heating can overcome the above problems fully; it is the complex manufacturing technology of infrared ceramic plate that but there is common problem for a long time in the infrared ceramic radiation heating board on the infrared gas stove tool burner; the host material poor stability of ceramic wafer; the process standardization difficulty is very big; poor sealing performance when potsherd combines with metal shell; the infrared ceramic plate is after making kitchen range simultaneously; kitchen range bursting and weathering of infrared ceramic plate usually can occur in the process of using; and in a single day the infrared ceramic plate occurs bursting with this table cooker tool of weathering and tempering phenomenon will occur; and in a single day a table cooker tool occurs that tempering will cause will whole table cooker tool burning out may, in a single day kitchen range burn out and will cause bigger danger.Therefore, though the every technical indicator of infrared gas stove tool is generally acknowledged all good, above problem can not be solved for a long time at all, is restricting the development and the popularization of infrared gas stove tool product.

Summary of the invention:

The purpose of this utility model is to overcome the weak point of the technology that has infrared burner now, provide a kind of manufacture craft simple, standardization level height, percent opening height, can weathering, the infrared metal honeycomb burner of the gas appliance that infrared radiation panel can not burst.

The technical scheme that provides of the utility model is for achieving the above object: include induction tunnel and burner and mix the gas air chamber.The gas outlet of induction tunnel is stretched into from the sidewall that mixes the gas air chamber or bottom and is mixed in the gas air chamber, will be with the be superimposed with each other welding or twine infrared metal honeycomb that the gas appliance of making of welding uses and adopt the sidewall of inlaying ways of connecting and the gas outlet internal diameter of the mixed gas air chamber of burner to be connected to become the infrared ray honeycomb burner of bilayer or multilayer metal foil.

The gas outlet that described burner mixes the gas air chamber can be a gas outlet independently, the combustion front that the infrared metal honeycomb of this gas outlet constitutes can be a horizontal firing face, matrix combustion front, convex combustion front or convex-concave combustion front, described alone in one plane or form infrared metal honeycomb burner on the concave surface, also can make by a plurality of infrared metal honeycombs combinations; The gas outlet of mixing the gas air chamber also can be independently plural or relatively independent gas outlet, on the madial wall of each gas outlet, inlay be fixed with one independently or relatively independent infrared metal honeycomb constitute independently or relatively independent combustion front, these independently or relatively independent combustion front form a complete burning group.

In addition, also can be provided with air communication channel in the centre that burner mixes the gas air chamber and between the madial wall of the lateral wall of air communication channel and mixed gas air chamber gas outlet, inlay the ring-like infrared metal honeycomb that is fixed with center drilling.

The utility model has been done overall technology improvement and technological break-through at the deficiency of existing infrared burner, replaced the ceramic radiation plate of prior art with infrared metal honeycomb, has thoroughly solved the infrared ceramic plate and has been easy to burst defective with weathering.The utility model has adopted bilayer or multilayer metal foil to make and porous infrared ceramic plate identical function porous infrared metal honeycomb, and mode direct and that burner mixes the outlet internal diameter position welding of gas air chamber, it is simple to have reached manufacture craft, the standardization level height, the percent opening height, effect that can weathering has been stopped heat radiation plate and has been burst generation with phenomenons such as poor sealings, more tempering phenomenon can not occur.The burner heat made from the utility model technology is negative big, and heat is imitated high, and the noxious gas emission of NXOization thing and CO is extremely low.The utility model has adopted fully premixed flameless combustion and infrared radiation heating technique simultaneously, can not produce free carbon sooting cooker, and every the key technical indexes and discharge of harmful gases are well below national standard and international standard.The utility model technology can reach more than 20% comparing energy savings with normal domestic use atmospheric gas kitchen range, be used in that fractional energy savings can reach more than 20% equally on baking oven, baking box, gas heater, the gas fired-boiler, as to compare energy savings more considerable with air suspended type Chinese meal cooking gas kitchen ranges, fractional energy savings can be up to more than 40%.It is extensive that the utility model adapts to source of the gas, more in large-scale production, sale and popularization, is being badly in need of under the energy savings form simultaneously, for country saves a large amount of energy, also brings new life to the gas kitchen ranges industry.
