Detailed description of the invention
Close injector below in conjunction with the drawings and specific embodiments to a kind of gas premixing for infrared cooker burner of the present utility model to be described in detail.
As shown in Figure 1, close injector according to the gas premixing for infrared cooker burner of the present utility model and comprise collapsible tube 11, mixing tube 12, spacer 13 and nozzle 14.One end of collapsible tube 11 connects mixing tube 12, and the other end of collapsible tube 11 connects spacer 13.Nozzle 14 is inserted in collapsible tube 11 by the center hole part that is formed centrally in spacer 13.Collapsible tube 11, mixing tube 12 and spacer 13 are the integrated design, and mixing tube 12 is detachably connected to burner drain pan 23 by diffuser pipe 22, thus can realize the part that burner drain pan and gas premixing close injector and be separated.
Particularly, according to an embodiment, collapsible tube 11 can be hollow taper pipe, and the wide mouth place of collapsible tube is air inlet, and described air inlet connects spacer 13.The slot place of collapsible tube is gas outlet, and described gas outlet connects mixing tube 12.Preferably, the air inlet diameter of collapsible tube 11 is 29mm, and the gas outlet diameter of collapsible tube 11 is 20mm, and the length of collapsible tube 11 is 50mm.But above-mentioned size is only illustrative at this, and does not mean the size of collapsible tube to be limited to this.
Mixing tube 12 can be hollow circular cylinder, and the tube wall of mixing tube 12 is provided with instrument connection 121, and this instrument connection is used for matching with testing arrangement in testing.Preferably, the length of mixing tube 12 is 52mm, and the diameter of instrument connection 121 is 8mm, and the distance of the center of instrument connection 121 and the terminal edge of mixing tube 12 is 15mm.
Alternatively, spacer 13 can be cylinder, and the inwall of the centre bore of spacer arranges metric fine internal thread.Spacer 13 such as can pass through corrosion resistant plate or galvanized sheet punch forming.Preferably, the thickness of spacer can be 1mm, and the diameter of centre bore is 9mm.
Nozzle 14 can be hollow circular cylinder alternatively.The air inlet end of nozzle arranges nozzle fixed screw 141, the tube wall arranged outside metric fine external screw thread of the gas outlet end of nozzle, the gas outlet end 20mm of described metric fine external screw thread distance nozzle 14.Nozzle 14 to be engaged with metric fine internal thread by metric fine external screw thread and is inserted in collapsible tube 11, and is threadedly engaged nozzle 14 can be regulated to insert length in collapsible tube 11 by this, thus can the distance of accurately Control Nozzle and mixing tube entrance.
In test environment as shown in Figure 2, air compressor 33 connects nozzle 14, and air compressor 33 and nozzle 14 junction arrange flowmeter 32.One end slot inlet end 21 of diffuser pipe 22 connects mixing tube 12, and other end Kuan Kou gas outlet connects burner drain pan 23.The slot inlet end 21 of diffuser pipe does not hide the instrument connection 121 on mixing tube 12, instrument connection 121 Bonding pressure meter 31.Regulate the charge flow rate of nozzle 14 to reach rated value, pressure gauge 31 reading that rotating shrinking pipe 11 makes instrument connection 121 connect is minimum, and outside stationary positioned sheet 13 and nozzle 14 tube wall on fine thread.
It is relevant that the gas premixing of infrared cooker burner closes the shape of the diameter of performance with mixing tube of injector, collapsible tube and pressure inlet, latus rectum and the factors such as relevant position and bleed pressure size thereof.The minimum mark being injector and being in optimum Working is reached at mixing tube internal face static pressure.
Existing burner drain pan and gas premixing close in injector integrated design, and diameter accuracy, the injector inwall fineness of mixing tube improve the restriction being subject to cost.The distance of nozzle distance mixing tube entrance is subject to kitchen range bottom shell, valve body, the foozle of burner, the restriction of alignment error, is difficult to reach optimum value.Therefore existing infrared kitchen range is made to be difficult to reach optimum Working.
According to the utility model, burner drain pan and gas premixing close injector part and are separated, the collapsible tube of gas premixing conjunction injector, mixing tube and nozzle integrated design.When burner overall structure is constant, can the distance of accurately Control Nozzle and mixing tube entrance, make full use of fuel gas injection kinetic energy, introduce more air, make infrared kitchen range reach the effect of optimum Working.
As shown in Figure 3, during kitchen range assembling, instrument connection 121 is hidden by the slot inlet end 21 of diffuser pipe, and nozzle 14 connects gas valve body 41.In actual use, nozzle calculates than according to 1.08 with the distance of mixing tube entrance and the diameter of mixing tube, the theoretical value of the distance of nozzle and mixing tube entrance is 22.56mm, and can control actual value in the distance of nozzle and mixing tube entrance by regulating the nozzle length inserted in mixing tube is between 22.3mm to 22.8mm.The distance of nozzle and mixing tube entrance and the diameter ratio of mixing tube, between 1.07 to 1.09, are no more than 1% to the impact of induction efficiency.Therefore, gas premixing of the present utility model closes injector under the condition significantly reducing far infrared kitchen range manufacturing cost, makes infrared kitchen range easily reach optimum Working, improves the efficiency of combustion of infrared kitchen range.
Finally it should be noted that, above embodiment is only in order to describe the technical solution of the utility model instead of to be limited, the utility model can extend in application other amendment, change, application and embodiment, and therefore think that all such amendments, change, application, embodiment are all in spirit of the present utility model and teachings.
