Abstract
The utility model relates to a gas oven which is used for making food. A control part of the utility model is composed of a main control valve and a temperature control valve. The main control valve is composed of an ignition protector, an extinction protector and a two-way valve. The temperature control valve is composed of a temperature controller and an electromagnetic valve. Main gas is sent to an ignition tube and a gas burner to be ignited and burnt after passing through the two-way valve and the electromagnetic valve. The utility model has the functions of constant temperature, reignition after accidental extinction or air supply closing. The utility model is characterized in that the structure is simple; the utility model is practical and reliable; the accuracy and the sensitivity are high; the baking effect is good; the utility model is provided with a safety protecting device for the accidental extinction; the cost is low; the installation and the maintenance are convenient, etc.
Description
The utility model is a kind of fuel gas oven that food is used of making.
At present, domestic food oven all is to adopt infrared ray electric heating baking oven, and weak point is: the thermal efficiency is low, and cured effect is not good, and cost of manufacture is high.External fuel gas oven, control section is that igniting, temperature control and valve body are constituted an integral body, and adopt piezoelectric ceramic ignitor and mechanical temperature controller to utilize lever principle to make the control valve conducting or close by air-flow, thereby reach the purpose of baked goods, its weak point is: structure, part processing complexity, the pore of temperature controller are stopped up easily and are caused temperature control malfunctioning, the not ideal enough deflagration phenomenon that is prone to of igniting effect, the cost height, maintenance, installation difficulty etc.
The purpose of this utility model is exactly that a kind of rational in infrastructure, practical and respond well fuel gas oven is provided in order to overcome above-mentioned weak point.
Control section of the present utility model is made up of main control valve 1 and temperature control valve 2, and main control valve 1 is to be made of igniting and blowout protection device and two-port valve 3, and temperature control valve 2 is to be made of temperature controller 4 and magnetic valve 5.Igniting and blowout protection device are to be made of igniting and blowout protection IC 1 and inducing probes 10, are connected in series between the coil L of IC 1 and temperature controller 4 and magnetic valve 5.The main gas outlet 6 of two-port valve 3 is connected with the air inlet 7 of magnetic valve 5, and the gas outlet 8 of magnetic valve 5 then is connected with the Gas Pipe 9 of burner and igniter.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a contour structures schematic diagram of the present utility model.
Fig. 2 is main control valve of the present utility model and temperature control valve connection diagram.
Fig. 3 is the utility model electrical schematic diagram.
Fig. 4 is burner of the present utility model and igniter structural representation.
Referring to Fig. 1～Fig. 4, main control valve 1 of the present utility model and temperature control valve 2 are two independent valve respectively, and main control valve 1 is one one step valve, and temperature control valve 2 is secondary valves.Magnetic valve 5 in the temperature control valve 2 for discharging closed condition, is the adhesive opening during energising when outage.Igniting and blowout protection device are to adopt the pulse firing mode, the good reliability of igniting, and when the kindling material accident was extinguished, igniting and blowout protection were thought highly of newly and are lighted a fire, and make kindling material keep fired state; When continuous igniting still can not make kindling material keep fired state about 11 seconds; inducing probes 10 will be exported a signal quits work igniting and blowout protection device; cut off the power supply of magnetic valve 5 simultaneously; make magnetic valve 5 be in the outage closed condition; thereby close source of the gas, reach the purpose of safe handling.The utility model has four infrared gas burners 11, in the inside of shell and door the heat-insulation and heat-preservation material is arranged all.
When using the utility model, press main control valve 1 and half-twist angle left earlier, at this moment igniting of main control valve 1 and blowout protection device are lighted kindling material, and then just can open main control valve 1 to anticlockwise, make magnetic valve 5 be in the energising opening simultaneously, make the combustion gas body be transported to burner 11 and igniter 12 by Gas Pipe 9 from the gas outlet 8 of magnetic valve 5, by igniter 12 burner 11 is lighted and burnt by kindling material, the utility model is started working, cavity temperature raises in making, when temperature reaches the indicated temperature of temperature control valve 2, temperature controller 4 will make magnetic valve 5 be in the outage closed condition automatically, stop to make burner 11 burn-outs to burner 11 and igniter 12 air feed, kindling material then continues to keep lighting state; Drop to when the temperature of inner chamber in 3～5 ℃ of temperature controller 4 designated values, temperature controller 4 will make magnetic valve 5 be in energising adhesive opening again, burner 13 is rekindled and heat up, make inner chamber keep temperature constant state, thereby reach effect at the inner chamber baked goods.When the kindling material accident was extinguished, the utility model then can be lighted a fire again, made kindling material keep fired state; When continuous igniting still can not make kindling material keep fired state about 11 seconds; igniting of the present utility model and blowout protection device will stop igniting, cut off the power supply of magnetic valve 5 simultaneously, make magnetic valve 5 be in the outage closed condition; thereby close source of the gas, thereby reach the purpose of safe handling.When stopping using the utility model,, just can cut off source of the gas burner 11 and kindling material are extinguished as long as main control valve 1 is closed.
Characteristics of the present utility model are: 1, simple and reasonable, practical reliable; 2, The accuracy of temperature control and highly sensitive, cured effect is good; 3, has accident extinguishing Safety guard; 4, cost is low, and installation, maintenance is convenient etc.
