Description of drawings
Fig. 1 is the embodiment schematic diagram of energy-saving gas cooker of the present invention.
The specific embodiment
Its better specific embodiment comprises pan 1, body of heater 2, heat-storage type burner 3A and 3B, regenerator 4A and 4B, gas flow control valve 5A and 5B, reversing control valve 6, temperature- control adjustment device 7A and 7B, air-introduced machine 11, smokejack 12 as shown in Figure 1.
The normal temperature combustion air enters the high temperature air of regenerator 4A absorbing heat generation more than 600 ℃ through reversal valve 6 and Cryogenic air entrance 8, the combustion chamber that is sent in the kitchen range body of heater 2 as combustion air participates in burning, combustion gas enters through gas control valve 5A, light and in the combustion chamber internal combustion through burner 3A, a pot body 1 is heated.Pot body heating-up temperature can be by temperature-control adjustment device 7A control.At this moment, burner 3B and gas control valve 5B close.Produce the high-temperature flue gas more than 900 ℃ after the burning, enter into regenerator 4B through the high-temperature flue gas outlet again, after absorbing through heat absorption and heat storage chamber 4B, produce the low-temperature flue gas of 150-200 ℃ of temperature, low-temperature flue gas enters smokejack 12 discharges through low-temperature flue gas outlet 9 and reversal valve 6 under the effect of air-introduced machine 11.Through the commutation effect of reversal valve 6, low-temperature flue gas outlet 9 this moment is as the Cryogenic air entrance, and Cryogenic air entrance 8 is as the low-temperature flue gas outlet, and burner 3A and gas control valve 5A close, and burner 3B and gas control valve 5B open.The normal temperature combustion air enters into through reversal valve 6 and enter combustion chamber preparation participation burning after regenerator 4B absorbs heat in regenerator 4B, combustion gas enters through gas control valve 5B, light and in the combustion chamber internal combustion through burner 3B, pot body heating-up temperature can be by temperature-control adjustment device 7B control.Temperature was down to 150-200 ℃ after the high-temperature flue gas that burning produces entered regenerator 3A heat release, was exporting discharge through low-temperature flue gas.Afterwards, under the control of reversing arrangement, repeat above process.
Described pan and body of heater directly are connected and are integral, and make whole kitchen range become totally enclosed type.
The inside of described body of heater consists of the combustion chamber, at the wall of body of heater burner is housed, and body of heater is equipped with a pair of burner at least, can be provided with many to burner.
