Abstract
The utility model relates to a gas range, comprising a range plate, a switch body, an igniter, a gas supply pipe nozzle and a flame igniting nozzle. An electromagnetic valve is arranged in the switch body, and a thermocouple is arranged close to the range plate, so the gas source can be closed when the flame is extinguished in a fortuitous event. The utility model has simple structure, high safety and low cost.
Description
The utility model relates to a kind of gas kitchen ranges.
At present, the domestic gas-cooker that generally uses has electronic striking formula kitchen range and piezoelectricity sparking formula kitchen range, they all do not have automatic detection, kitchen range are normal use in because of fortuitous event when flame-out suddenly, automatically close the device of air supply source, make combustion gas after flame-out, still leak in a large number, thereby cause unnecessary loss.Abroad, Electronic Control is installed on gas kitchen ranges detects shutoff device automatically, complex structure is arranged, cost height, the problem of no battery cisco unity malfunction though have.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of cost low, and is simple in structure, reliable working performance, safe in utilization, the gas stove of solar term.
The purpose of this utility model can be reached by following measure: this gas stove comprises kitchen range dish, switch main body, ignition device, air supply pipe nozzle and ignition flame nozzle.Switch main body comprises air cavity, garden dial switch dish, return spring, sparking cam and air supply valve main shaft, has air supply opening, air inlet and sparking gas outlet on the air cavity, and air supply pipe nozzle and ignition flame nozzle are located at respectively on air supply opening and the sparking gas outlet.Installing one dividing plate is divided into epicoele and cavity of resorption with air cavity in air cavity, and air supply opening and sparking gas outlet are positioned at epicoele, and garden dial switch dish and air inlet are positioned at cavity of resorption.Have a passage relative with the air supply valve main shaft on the dividing plate, installing one magnetic valve makes the switchboard on the magnetic valve corresponding with the passage on the dividing plate in air cavity.Front end at the ignition flame nozzle is provided with a thermocouple I, is provided with a thermocouple II at kitchen range Pan Chu, and thermocouple I and thermocouple II are connected with solenoid in the magnetic valve.Be provided with a time-delay releasing device at ignition flame nozzle place, fore-set in the time-delay releasing device is matched with the ignition flame nozzle, on the air supply valve main shaft, be with an igniting cam, link together by mechanical drive mode between the fore-set of ignition cam and time-delay releasing device.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the circuit diagram of thermocouple of the present utility model and magnetic valve.
Fig. 2 is a switch main body cutaway view of the present utility model.
Fig. 3 is the structure chart of ignition flame nozzle of the present utility model and time-delay releasing device.
By Fig. 1, Fig. 2, Fig. 3 as can be known this utility model gas kitchen ranges by ignition flame nozzle (16), switch main body, existing kitchen range dish, existing ignition device.Existing air supply pipe nozzle (17) is formed, switch main body comprises air cavity (1), garden dial switch dish (2), return spring (3), sparking cam (4) and air supply valve main shaft (5), having air supply opening (6), air inlet (7) and sparking gas outlet (8), air supply pipe nozzle (17) and ignition flame nozzle (16) on the air cavity is located at respectively on air supply opening (6) and the sparking gas outlet (8), installing one dividing plate (9) in air cavity (1), it is divided into epicoele (10) and cavity of resorption (11) with air cavity.Air supply opening (6) and sparking gas outlet (8) are positioned on the epicoele wall, garden dial switch dish (2) is positioned at cavity of resorption, air inlet (7) is positioned on the cavity of resorption wall, and air supply valve main shaft (5) is with sparking cam (4), ignition cam (12), return spring (3) and garden dial switch dish (2) successively respectively.With the corresponding dividing plate of air supply valve main shaft (9) on have a passage (13), a magnetic valve (14) is installed on the wall of the epicoele (10) of air cavity, make the switchboard (15) on the magnetic valve corresponding with the passage (13) on the dividing plate (9), front end at ignition flame nozzle (16) is provided with a thermocouple I (P1), be provided with a thermocouple II (P2) in kitchen range dish vicinity, be connected with the lead that is surrounded by heat proof material between the solenoid (ZT) in thermocouple I (P1) and thermocouple II (P2) and the magnetic valve (14).Locate to be provided with a time-delay releasing device (18) (this time-delay releasing device (18) can be the mechanical damping formula or Hydrautic damping or the oil damping formula) at ignition flame nozzle (16).Fore-set (19) in the time-delay releasing device is matched with ignition flame nozzle (16).Link together by mechanical drive mode between the fore-set (19) of ignition cam (12) and time-delay releasing device.
Its operation principle is: when pushing with hand and rotating the air supply valve main shaft, the switchboard of the inside roof pressure magnetic valve of air supply valve main shaft, make gas circuit open-minded, magnetic valve armature is pressed on the electromagnet, make air supply valve main shaft return immediately by the time-delay releasing device, ignition device is lighted the igniting flame-thrower nozzle simultaneously, flame is also lighted the kitchen range dish subsequently, the thermocouple I in ignition flame nozzle the place ahead is heated immediately, and the fore-set of time-delay releasing device makes ignition flame can continue flame just to close gas circuit in nearly about 1 second, the low-voltage, high-current that the thermocouple I produces makes electromagnet produce magnetic force, hold armature, make the air feed road maintain open state, after ignition flame extinguishes, kitchen range dish flame makes near the thermocouple II it be warmed up to duty, the voltage of its generation just replaces the thermocouple I, make magnetic valve have normal voltage to keep gas circuit all the time and be in open state, when any factor causes unexpected stopping working, the thermocouple II loses thermal source, thereby make magnetic valve can not hold armature, make switchboard close passage under spring action, it is flame-out to finish automatic detection, automatically close the function of air feed.
The utility model has following advantage with respect to prior art: cheap, economize on gas, and use safety, simple in structure.
