The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As 1 to shown in Figure 6, the refrigerator that heat energy drove 2, magnetic valve 4, pulse ignition device, battery 5, power switch 6 and control module 7 that the automaton of this combustion gas refrigerator comprises the burner 3 that is arranged on refrigerator body 1 rear, produced by burner 3 burnings.The gas valve 9 that wherein said magnetic valve 4 connections and control are connected with source of the gas is with the switching of control gas source, and present embodiment adopts normally closed solenoid valve.Described pulse ignition device comprises battery, high-tension coil 18 and igniting inductive needle 10, and battery described in the present embodiment and battery unite two into one.The output of one end link control module 7 of described high-tension coil 18, an end connect igniting inductive needle 10; Described igniting inductive needle 10 is positioned at the air inlet place of burner 3, one end of thermocouple 11 connects the temperature of igniting inductive needle 10 with real-time inductive ignition inductive needle 10, the input of the other end link control module 7 of thermocouple 11 is delivered to control module 7 in real time with the temperature of its igniting inductive needle of sensing.The effect of described thermocouple is to detect the temperature in the burner 3 and temperature signal passed to control module, whether is in fired state to judge burner 3.Described power switch 6 is used for the switching of manual control circuit.The IC integrated circuit of described control module 7 for adopting routine techniques, designing according to the required function that has.
Be provided with the hurricane globe 12 of heat resistant glass material around the outside of burner 3, be installed with optical energy power plate 13 on the outer wall of hurricane globe 12, the light generating that utilizes burning to be produced, optical energy power plate 13 reaches its indicator lamp that connects 14 with the electric weight one road that is produced, and described indicator lamp 14 is arranged on the place ahead of refrigerator body; Another road then reaches battery 5 and stores.What be connected with battery 5 is arranged on illuminating lamp 8 and gate controlled switch 15 in the refrigerator in addition.
During initialization, manually close energize switch 6, the integrated circuit in the control module 7 gets electric, supplies power to igniting inductive needle 10 continuously at the time inner high voltage coil of setting 18, and while opens solenoid valve 4 air feed, igniting inductive needle 10 discharge electric spark and light burner 3.After burner 3 burnings, 10 heatings of igniting inductive needle, temperature signal reaches control module 7 through thermocouple 11, and control module 7 is cut off the electricity supply automatically, stops the power supply of high-tension coil 18.After burner 3 burnings, the electric weight one tunnel that optical energy power plate 13 is produced makes indicator lamp 14 luminous, so can observe the working condition of burner and refrigerator easily from the place ahead of refrigerator, the refrigerator that again need not overturn inspection flame-observing hole judges whether refrigerator has worked; Another road reaches battery 5 and stores, for future use.When burner 3 is put out by wind or other reason when extinguishing unusually, igniting inductive needle 10 temperature decreases, thermocouple 11 reaches control module 7 in real time with temperature signal, control module 7 is closed logical IC integrated circuit (required electric weight is provided by battery) immediately, make high-tension coil 18 supply power to igniting inductive needle 10 continuously, light combustion gas; If do not lighted yet at inner burner 3 at certain hour, then control module 7 will be closed high-tension coil 18 and magnetic valve 24 at once, cut off air feed.After carrying out the maintenance of circuit, gas circuit and finishing, manually to close energize switch 6, restart work again.The automaton of combustion gas refrigerator provided by the utility model has control and the defencive function that postpones outage and cut off source of the gas immediately concurrently, also is the efficient apparatus that prevents that combustion gas from leaking outside.
The refrigerator operate as normal makes, and whether the work of burner and refrigerator is to be controlled by the real time temperature in the refrigerator.When the cold degree in the refrigerator does not reach desired temperature, burner and refrigerator operate as normal; When the cold degree in the refrigerator had reached setting value, the temperature sensor in the refrigerator reached control module 7 with temperature signal, and control module 7 control magnetic valves 4 cut out, and stop air feed, and burner and refrigerator quit work; At this moment, the optical energy power plate no longer produces electric weight, and indicator lamp 14 extinguishes.The temperature that reaches control module when temperature sensor is during greater than setting value, and the automatic opens solenoid valve of control module is also closed circuit passband, lights combustion gas, and burner and refrigerator restart work.
During burner operation, the unnecessary electrical power storage that the optical energy power plate is produced is in battery.When opening refrigerator doors, gate controlled switch 9 closes logical automatically, and illuminating lamp 8 gets electroluminescence, the illumination refrigerator; When refrigerator doors is closed, the gate controlled switch automatic disconnection.
As shown in Figure 3, this combustion gas refrigerator also can install the power line 15 and the electrothermal tube 16 that become parallel connection to concern with burner at the rear of refrigerator body additional and drive refrigerator work.Like this, this refrigerator can use fuel gas buring to drive, but also electrification drives, and allows the many one decks of consumer select, and any energy is convenient, just with any, exchanges at any time.
