Abstract
The utility model discloses a gas heater combustor with return fire control system function, including combustor cavity 2, ejector 1, fire hole 3 and firing level 4, one end and the ejector 1 of combustor cavity 2 link to each other, the other end links to each other with fire hole 3, 3 upper portions in the fiery hole connect firing level 4, its characterized in that: the main part outer wall of combustor on be equipped with temperature -sensing ware 6, temperature -sensing ware 6 and controller 5 link to each other. The utility model discloses a combustor can accurately detect the tempering situation of cooking utensils, cuts off the supply of gas, avoids owing to draw a temper the incident that arouses.
Description
Technical field
This utility model relates to a kind of water heater combustor, particularly relates to a kind of gas heater burner with back-fire controlling function.
Background technology
Extensively utilizing and effectively utilizing along with the energy, the raising of people's living standard, gas heater is widely used in a variety of applications.For improving safety, gas heater product the most on the market is generally equipped with protector of accident extinguishing.But, this device can only detect the combustion conditions at combustion front, and i.e. it can only provide for safeguard protection during water heater accident extinguishing, and can not detect other abnormal combustion situation of burner.When tempering occurs in burning, owing to the combustion flame of combustion front is normal, protector of accident extinguishing still can detect combustion flame, controller can maintain normal valve opening to supply, it is impossible to judges improper combustion case, cuts off source of the gas supply.Tempering burned flame can burn at injector or burner outer surface, is easily burnt by burner, causes the most serious security incident.
Utility model content
Technical problem to be solved in the utility model, it is simply that provide a kind of gas heater burner with back-fire controlling function, it can accurately detect the tempering situation of kitchen range, cut off the supply of combustion gas, it is to avoid the security incident caused due to tempering.
Solving above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
A kind of gas heater burner with back-fire controlling function, including burner cavity 2, injector 1, fire hole 3 and combustion front 4, one end of described burner cavity 2 is connected with injector 1, the other end is connected with fire hole 3, described fire hole 3 top connects combustion front 4, it is characterized in that: the body outer wall of described burner is provided with temperature inductor 6, described temperature inductor 6 is connected with controller 5.
When gas heater burner occurs tempering, back fire flame can cause the temperature of burner body outer wall to raise rapidly, and when its temperature reaches the operating temperature of temperature inductor 6, temperature inductor 6 sends tempering signal.When controller obtains tempering signal, i.e. issue an instruction to close gas electromagnetic valve, cut off the supply of combustion gas.The operating temperature of temperature inductor is not less than 200 DEG C.
Preferably, described temperature inductor 6 is located on the outer wall of described injector 1 or burner head.
Beneficial effect: this utility model simple in construction, it is possible to be accurately detected the tempering situation of kitchen range, improves the safety of gas heater.
