Abstract
The utility model belongs to a thermoelectric type automatic closing safety gas range when flameout occurs, which is mainly composed of a central flame cover, an outer ring flame cover, an igniting device and a thermoelectric type flameout and protection device. The utility model is characterized in that the thermoelectric type flameout and protection device comprises a thermocouple temperature sensor, an electromagnetic safety valve and a plug valve; the safety valve and the plug valve are installed in the same valve body; a valve port I which can be communicated with a gas inlet and a valve port II which can be communicated with the safety valve are arranged in the plug valve. Particularly, during the using process of a range, when combusting flames are extinguished by accident because of blowing, rice overflow, sudden temporary gas cut, etc., gas sources can be automatically cut off in a short time.
Description
The utility model belongs to a kind of gas kitchen ranges, particularly in the flame-out automatic closed safe kitchen range of a kind of thermoelectric (al) type.
Along with the universal use of gas appliance, its security performance is also paid close attention to by the people day by day, the gas kitchen ranges of Chu Shouing mostly is common eyes kitchen range in the market, and great majority do not have extinguish protection function.And in daily use owing to wind, overflow meal or suddenly provisional reason such as stop the supple of gas or steam, when burning and flame are extinguished simultaneously, can in very short time, combustion gas continue to leak, cause poisoning, meet fiery accident such as fried and take place, create greater casualties and accident for user's lives and properties.
The purpose of this utility model is the generation that will prevent above-mentioned casualty accident in the existing kitchen range, proposes the flame-out automatic closed safe gas kitchen range of a kind of thermoelectric (al) type, and it sets up the flame-out igniter of closing automatically of thermoelectric (al) type in general gas kitchen ranges.
The technical scheme of the flame-out automatic closed safe gas kitchen range of thermoelectric (al) type of the present utility model is: it is mainly by shell; leg; drip pan; pot supporter; middle internal heat lid; external ring fire cover; igniter and thermoelectric (al) type flame-out protection device constitute; it is characterized in that the thermoelectric (al) type flame-out protection device comprises thermocouple temperature sensor; electromagnetic valve and plug valve; safety valve and plug valve are contained in the same valve body; be provided with valve port I that can connect with air inlet and the valve port II that is communicated with safety valve in the plug valve; the igniting gas circuit that also has valve port to be connected with piezoelectric ignition device connects; the other end of electromagnetic valve is connected with temperature sensor, and is provided with the gas outlet on its valve body.Near internal heat was covered during thermocouple temperature sensor in the described thermoelectric (al) type flame-out protection device was installed in; it has pipeline to be communicated with electromagnetic valve; produce electromotive force by middle internal heat lid burned flame heating sensor, the iron core in the excitation electromagnetic valve holds armature, and safety valve is opened.One end of described plug valve is provided with knob, by pushing and rotation the valve port II between safety valve and the plug valve is opened.Internal heat lid 2-4mm in the tip distance of temperature sensor, the operating temperature of sensor is 500 ℃～650 ℃.
These kitchen range have switch and light the function of combustion gas, regulation and control gas flow.Particularly when burner in use owing to wind, meal are overflow, when suddenly provisional reason such as stop the supple of gas or steam is extinguished the burned flame accident, can be closed source of the gas automatically in very short time.Prevent the poisoning that continues to leak and cause because of combustion gas, meet the generation of fiery accident such as fried.
These kitchen range mainly contain compositions such as flame-out protection device, plug valve, piezoelectric ignition device.Formed the blast tube of bivalve mouth by the safety valve in plug valve and the flame-out protection device, closed when arbitrary valve port wherein and can cut off source of the gas.
Flame-out protection device is made up of flame sensor and safety valve, will produce electromotive force when main burner flame heat sensor tip end, can encourage safety valve work to make circuit be in opening though this electromotive force is faint.When the flame accident was extinguished, the sensor tip end region temperature descended.Electromotive force reduces gradually, the valve port of safety valve automatic self-closing gas passage under its spring action.Stoped combustion gas to leak.
When opening the switching point firearm, should at first push and promote the knob plug valve counterclockwise, safety valve all is in opening, and combustion gas flows to the main burner gas circuit of meanwhile lighting a fire and also opens, wait to hear " " during sound, piezoelectric ignition device is lighted flame automatically.Under this state knob is compressed, keep the several seconds, the flame of main burner just is heated to operating temperature with sensor.Too early, safety valve does not also enter normal operating conditions if loose one's grip, and safety valve cuts out blast tube under its spring action.Should repeat above-mentioned opening process this moment.
Turning knob adjustable fuel gas stream changes flame size.
Clockwise rotate when closing combustion gas knob to hear " " sound.
The key technical indexes:
1, flame-out protection device, interior energy operate as normal back 5-8 second of lighting a fire automatically; Fire extinguishing back 4-6 closes source of the gas automatically in second.
2, air-tightness, lighting rate meet the requirement of CJ4-83 standard.
In order to further specify structure of the present utility model, reach embodiment with reference to the accompanying drawings and specifically describe.Its accompanying drawing has:
Fig. 1 kitchen range outside drawing;
Fig. 2 flame-out protection device structure chart.
In Fig. 1-2: 1 shell, 2 drip pans, 3 pot supporters, 4 temperature sensors, internal heat lid in 5,6 external ring fire covers, 7 knobs, 8 legs, 9 piezoelectrics, 10 igniting gas circuits, 11 air inlets, 12 gas outlets, 13 safety valves, 14 valve bodies, 15 valve port II, 16 valve port I, 17 plug valves.
Embodiment:
Safety fuel gas kitchen range shown in Fig. 1-2, it is by shell 1, leg 8, drip pan 2, pot supporter 3, middle internal heat lid 5, external ring fire cover 6, knob 7, piezoelectricity pottery magnetic igniter 9, igniting gas circuit 10 constitutes, safety valve 13 and plug valve 17 are contained in the same valve body 14, and the place is provided with the gas outlet at safety valve body, are provided with air inlet and valve port I in faucet valve, be provided with valve port II at safety valve 13 and 17 of plug valves, press knob 7 to make plug valve 17 and safety valve 13 all be in opening.
