Specific implementation mode

Below in conjunction with the accompanying drawings and specific embodiment is further elaborated the utility model.

As shown in Figure 1, a kind of energy-saving gas cooker of the present embodiment, including shell 1, the upper surface of shell 1 offer a pot hole, For placing cooker pan, the circumference in pot hole is equipped with a circle pot holder 11 in pot hole, 11 surface of pot holder and the bottom of a pan middle and lower part outside wall surface it Between form gas-tight contact, prevent gas-cooker flare and flue gas stream outside alter.

Burner 2, mixing chamber 3, guide shell 4, the first coil pipe 5 and the second coil pipe 6 are equipped in shell 1, burner 2 is located at pot Below hole, guide shell 4 is set to 2 periphery of burner, and the upper end of guide shell 4 is connected with shell 1, lower end and the shell 1 of guide shell 4 It is pipe or square tube that bottom, which has gap, guide shell 4,.

Mixing chamber 3 is separately connected burner 2 and natural gas tube 7, and natural gas tube 7 is equipped with valve.First coil pipe 5, which is located at, leads It in flow cartridge 4, is looped around outside mixing chamber 3, the both ends of the first coil pipe 5 are separately connected wind turbine 8 and mixing chamber 3.Wind turbine 8 is used for combustion gas Surrounding air outside stove is drawn into the first coil pipe 5, and the first coil pipe 5 is for recycling gas-cooker flue gas stream waste heat and heating the first disk Combustion air in pipe 5.

Second coil pipe 6 is located between 1 side wall of guide shell 4 and shell, and the both ends of the second coil pipe 6 are separately connected 9 He of water inlet pipe Outlet pipe 10, the second coil pipe 6 are used to recycle gas-cooker flue gas stream waste heat and heat the water in the second coil pipe 6.

In order to increase heat exchange efficiency, the first coil pipe 5 and the second coil pipe 6 are corrugated stainless steel tubing.

1 top of shell is connected with exhaust emission tube 12, and exhaust emission tube 12 is used for excluding the cigarette after backheat utilizes Gas exhaust gas.

The heat transfer process of above-mentioned energy-saving gas cooker is：

The natural gas entered from natural gas tube 7 with from the air that the first coil pipe 5 enters mixing chamber 3 is interior mix after burning The flue gas stream of 2 combustion heating cooker pan of device, generation of burning enters mixing chamber 3 from the annular gap of burner 2 and guide shell 4 and leads The space that 4 inner wall of flow cartridge surrounds, flue gas stream and the first coil pipe 5 carry out heat exchange, heat the air in the first coil pipe 5, then cigarette Air-flow enters the space that 4 outer wall of guide shell is surrounded with 1 side wall of shell, flue gas stream from the gap of 4 lower end of guide shell and 1 bottom of shell Heat exchange is carried out with the second coil pipe 6, heats the recirculated water in the second coil pipe 6, the flue gas stream after finally cooling down is discharged by exhaust gas Pipe 12 is discharged.

11 inner hollow of pot holder, 11 inner space of pot holder are connected to 1 inside of shell, and connectivity part is located at guide shell 4 and shell 1 Between side wall, the arrival end of exhaust emission tube 12 is connected with pot holder 11.Enter pot holder after 6 heat exchange of flue gas stream and the second coil pipe 11, pot holder 11 can transfer heat to cooker pan, further recycle heat.

As shown in Fig. 2, burner 2 includes hollow load bearing board 201, load bearing board 201 is arc, is opened up on load bearing board 201 There is spray orifice 202.It after natural gas enters load bearing board 201 by mixing chamber 3, sprays and burns from spray orifice 202, flame is by load bearing board 201 are heated to red heat, and at this moment load bearing board 201 is just provided with significant heat radiation effect, thus to the heat effect at cooker pan bottom In addition to thering is the direct effect of flame, also very strong radiant heating effect, two kinds of effects to keep cooker pan absorption heat with better function, It is more to absorb heat, firepower is also more violent.
