Abstract
A burner with back-fire control function for the domestic gas stove features that a temp sensor connected electrically with pulse ignition controller is closely attached to the gas inject tube of a burner. When back-fire takes place, the temp of said gas injection tube is increased and a signal is sent to the said pulse ignition controller to cut off the electromagnetic valve of gas, so extinguishing the fire.
Description
Affiliated technical field
The present invention relates to the improvement of household gas utensils buner system, especially to the improvement of household gas utensils burner safeguard protection.
Background technology
Along with the progress of society, the extensive utilization of the energy, household gas utensils have spread to huge numbers of families, and people are also more and more higher to household gas utensils instructions for use and security of products requirement, and people can require also more and more higher to security of products.Household gas utensils are the products that the tight security requirement is arranged, and the relatively large leakage of combustion gas and improper burning can cause the loss of product self and family's property, and severe patient entail dangers to people's safety is a problem that is worth people to pay much attention to.For example, when family expenses gas kitchen ranges during because of a variety of causes generation tempering, if can not in time close the supply of burnt gas valve or cut-out combustion gas, can or burn out kitchen range product scaling loss, if after not closing burnt gas valve for a long time or cutting off the supply of combustion gas, then may cause fire incident, severe patient can cause jeopardizing people's life security.And present on the market household gas utensils product; though some has ion detection type or two kinds of protector of accident extinguishing of electrothermic type (being temperature mode) product as safeguard protection; but these products also do not have the tempering safety protection function; can't carry out security control to tempering when tempering appears in cooker burner, there is following aspect defective in they:
(1) adopt ion detection type protector of accident extinguishing to make the kitchen range product of safeguard protection; the combustion position that it detected is the flame situation of just interior ring fire all; the flame situation of ring fire simultaneously externally detects; can burner be burnt because of the tempering of ring fire outside can't detecting when tempering appears in outer ring fire, accident appears in severe patient.
(2) for adopting ion detection type protector of accident extinguishing to make the kitchen range product of safeguard protection, because detecting, its flame is the flare up fire on the burner fire hole, when tempering appears in burner, even tempering appears in the interior ring fire of dicyclo ignition combustor, it detects inductive needle is to be installed on the flame situation that detects interior ring fire, but because flame still is present in the induction tunnel of burner, on cavity and the quirk, protector of accident extinguishing still can detect combustion flame, the flame that still can regard normal combustion as, the pulse firing controller still can be kept and hold the valve air feed normally, can not the improper burning of tempering situation be judged, cut off the source of the gas supply; Safeguard protection effect in the time of can not reaching tempering.This can burning or security incident occurs burner.Burner backfire situation security control to monocycle ignition combustor kitchen range also is like this.
(3) adopt the electrothermic type protector of accident extinguishing to make the kitchen range product of safeguard protection; because no electronic control system; it is to carry out safety protection control by the mode of the induction temperature difference; no matter be outer ring fire tempering or interior ring fire tempering; on its thermocouple induction head, all still sense temperature; still can regard normal combustion as, can not detect the situation of burner backfire, cut off the control of source of the gas in the time of more can not tempering occurring cooker burner.
Summary of the invention
The objective of the invention is, adopt electronically controlled way, by improvement cooker burner tempering security control mode, increase tempering safe temperature checkout gear, detect the tempering situation of cooker burner exactly, and cut off the control of gas supply, to reach purpose safe in utilization.
The present invention realizes by following technical solution: a kind of household gas utensils burner with tempering control function, by furnace chamber (1), induction tunnel (2), fire hole burner plate (3), pulse firing controller (4) is formed, there are temperature inductor (5) and pulse firing controller (4) to link, temperature inductor (5) is positioned over trunnion or anemostat outside (6) that induction tunnel (2) exposes to furnace chamber (1), or be positioned on furnace chamber (1) outside of induction tunnel (2) port of export, and make temperature inductor (5) and trunnion or anemostat outside (6), or close proximity can directly be conducted heat outside the furnace chamber (1) of induction tunnel (2) port of export, and the operating temperature of temperature inductor (5) is for being not less than 200 ℃; When tempering appears in gas burner; back fire flame can cause that induction tunnel (2) exposes to the trunnion of furnace chamber (1) or anemostat outside (6) or is positioned over the rapid rising of furnace chamber (1) temperature outside of induction tunnel (2) port of export; when its temperature reaches the operating temperature of temperature inductor (5); just can judge the generation of tempering situation by responding to its variation of temperature; pulse firing controller (4) obtains the tempering signal that tempering appears in gas burner; promptly sending instruction makes combustion gas control magnetic valve close valve; cut off the supply of combustion gas, thereby reach the purpose of safeguard protection.The household gas utensils burner that the present invention is suitable for, comprise atmospheric burner and infrared burner two big classes, it can be single induction tunnel burner of monocycle fire, can be two induction tunnel burners of the independent control of dicyclo fire, can be the three induction tunnel burners that three ring fires are independently controlled.For single induction tunnel burner of monocycle fire, only need a temperature inductor to get final product.Two induction tunnel burners for the independent control of dicyclo fire, need two temperature inductors to be close to trunnion or the induction tunnel outside that is placed on two induction tunnels that expose to furnace chamber (1) respectively, or the temperature inductor (5) of outer ring fire tempering control can be positioned on furnace chamber (1) outside of outer ring fire induction tunnel (2) port of export, respond to the temperature variations of inside and outside ring fire induction tunnel trunnion respectively, tempering situation with ring fire inside and outside the judgement burner, no matter be that the tempering situation appears in interior ring fire or the tempering situation appears in outer ring fire, can both correctly detect, and command pulse ignition controller (4) is closed combustion gas control electromagnetic valve, cut-out gas supply.The three induction tunnel burners of independently controlling for three ring fires, the temperature inductor (5) of trunnion that then needs three temperature inductors to be close to respectively to be placed on three induction tunnels that expose to furnace chamber (1) or induction tunnel outside or outer ring fire tempering control can be positioned on furnace chamber (1) outside of outer ring fire induction tunnel (2) port of export, respectively in the induction,, the temperature variations of outer three ring fire induction tunnel trunnions, no matter be that the tempering situation appears in which ring fire, can both correctly detect, and command pulse ignition controller (4) is closed combustion gas control electromagnetic valve, cut-out gas supply.
The invention has the advantages that, can realize accurate detection, and can in time cut off the supply of gas source, effective safeguard protection is carried out in the tempering of gas burner gas burner tempering situation.
