Description
Technical field
The utility model relates to a kind of gas kitchen ranges UTILIZATION OF VESIDUAL HEAT IN generating and air-fuel ratio built-in stabilizers.
Background technology
Along with the raising of living standards of the people, gas kitchen ranges has been come into huge numbers of families, and owing to comprehensive startup of China's West-East National Gas Transmission Project, the popularity rate of gas kitchen ranges product also constantly raises simultaneously.At present the primary structure of the gas kitchen ranges that uses is to be provided with burner on stove, connects the wireway of burner and fuel gas source, and using electricity system such as the solid-state ignition system safety system of unifying, the solid-state ignition system safety system of unifying is mainly used dry cell power supply.But at present there is following point in the gas kitchen ranges of China: 1, the solid-state ignition system safety system of unifying is mainly used dry cell power supply; its electric weight of dry cell power supply is limited; service life is short; must regularly replace; not only use trouble, more seriously discarded dry cell can cause huge environmental pollution.2, traditional gas kitchen ranges in the course of the work, because actual gas supply amount constant (user opens the size of finely tuning gas valve behind the gas kitchen ranges seldom again), and the fresh air that enters burner expands because of the heat effect of air intake duct, the ratio of fresh air and combustion gas is reduced, cause incomplete combustion, produce exhaust emission and waste of fuel.3, fuel heat utilization on average has only 55%, and low fuel heat utilization has caused the pollution of severe energy waste and environment.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, provide a kind of waste heat that utilizes gas kitchen ranges to generate electricity and the ratio of automatic stabilisation combustion gas and air, make the solid-state ignition system of gas kitchen ranges " passive " system that safety system becomes does not need the external world that electric energy is provided that unifies; And reduce gas kitchen ranges can not automatic stabilisation because of air-fuel ratio, cause incomplete combustion and the exhaust emission that produces and the gas kitchen ranges waste heat heat energy power-generating and the air-fuel ratio built-in stabilizers of waste of fuel.
In order to solve the problems of the technologies described above, gas kitchen ranges waste heat heat energy power-generating that the utility model provides and air-fuel ratio built-in stabilizers, the wireway that comprises burner, connection burner and fuel gas source, and gas-cooker using electricity system, heat collection piece one end closely contact with the shell of described burner, the other end closely links to each other with the hot junction of semiconductor generator, and the cold junction of described semiconductor generator closely links to each other with radiator; Described semiconductor generator is provided with electric storage device and is electrically connected with the gas-cooker using electricity system.
As a kind of improvement of the present utility model, between the cold junction of described semiconductor generator and described radiator, be provided with the combustion heater that closely links to each other, the air inlet pipe of described combustion heater is connected with fuel gas source, and the escape pipe of described combustion heater is connected with described burner by wireway.
Adopt the gas kitchen ranges waste heat heat energy power-generating and the air-fuel ratio built-in stabilizers of technique scheme, its operation principle is:
1, waste heat heat energy power-generating principle:
A heat collection piece is installed in the burner bottom, the heat energy that is produced when absorbing burner combustion, and with the hot junction of this thermal energy transfer to semiconductor generator.The cold junction of semiconductor generator then treat combustion gas by combustion heater heating and by radiator to the atmosphere distribute heat; treat that combustion gas and atmosphere absorb the heat energy that the hot junction of semiconductor generator passes over fully; make the hot junction of semiconductor generator and the temperature difference of cold junction become big; thereby make semiconductor generator externally produce electric energy; this electric energy is by the battery charge of current-limiting circuit to gas-cooker, makes the solid-state ignition system of gas kitchen ranges " passive " system that safety system becomes does not need the external world that electric energy is provided that unifies.
2, air-fuel ratio automatic stabilisation principle:
The heat energy that absorbs the semiconductor generator cold junction when treating combustion gas by heater expands; Meanwhile, also absorbing heat energy during the kitchen range air flue of fresh air by gas kitchen ranges expands, as long as appropriate design is treated the heat tunnel and the temperature of combustion gas, its coefficient of thermal expansion that adds is equated with the coefficient of thermal expansion that adds of fresh air, just can make the air-fuel ratio automatic stabilisation of burner.
Because the energy of above-mentioned generating and stable air-fuel ratio is from the waste heat of gas stove fire head, after taking the waste heat of gas stove fire head away, the temperature of gas stove fire head is reduced,, further improve the thermal efficiency of gas-cooker so system also has the inlet function of relative raising fresh air.
In sum, the utility model is the gas kitchen ranges waste heat heat energy power-generating and the air-fuel ratio built-in stabilizers of a kind of energy-conserving and environment-protective, easy to use and simple in structure, dependable performance.
