Technical field

The present invention relates to gas-cooker technical field, specifically a kind of internal combustion type waste heat recycles gas-cooker.

Background technique

At present there is problem following prominent in gas-cooker during use:

1, it burns insufficient, causing burning supplement the main reason for dividing is that the air inflow of air inlet can not provide combustion gas and fill Oxygen required for divided combustion；

2, a large amount of heat that burning generates is lost from stove mouth position, causes a large amount of thermal loss, reduce the benefit of combustion gas With rate, the waste of the energy is caused；

3, lower with the air themperature of combustion gas mixing, it is insufficient to can result in fuel gas buring；

4, after fuel gas buring, a large amount of heat is discharged to outside gas-cooker with exhaust gas, causes the waste of heat.

Summary of the invention

The purpose of the present invention is to provide a kind of internal combustion type waste heats to recycle gas-cooker, can make full use of in exhaust gases after combustion Heat improves heat utilization ratio, improves combustion gas utilization rate.

The present invention to achieve the above object, is achieved through the following technical solutions:

A kind of internal combustion type waste heat recycling gas-cooker, including outer cooking stove, the outer cooking stove inside are equipped with inner cooking stove, the interior stove Quirk is equipped between body and outer cooking stove, the outer cooking stove top is equipped with premixer, and the premixer side is equipped with gas inlet pipe, The premixer other side is equipped with air intake duct, and described air intake duct a part is located in quirk；

The premixer end is equipped with discharge pipe, and the discharge pipe passes through inner cooking stove；

Flue is equipped with outside the outer cooking stove, the flue side is equipped with exhaust outlet, sets between the flue and outer cooking stove There are exhaust gases passes, the air intake duct passes through exhaust gases passes and is connected with the external world.

The premixer is equipped with protruding portion, and the protruding portion and outer cooking stove are adapted.

The part that the air intake duct is located in flue is parallel with flue inner wall.

The air intake duct is located at the portions end in flue equipped with blower.

The outer cooking stove top is 5-8cm higher than inner cooking stove top.

The air intake duct is two or more pieces, and the air intake duct is parallel.

Fire-resistant ring is equipped with inside the inner cooking stove, the discharge tube end is equipped with arc gaseous mixture spout, and the arc is mixed Gas blowout mouth is closed to match with fire-resistant ring.

The prior art is compared, the beneficial effects of the present invention are:

1, by premixer then air and combustion gas mixing are drained into inside inner cooking stove by discharge pipe again, realize burning, The exhaust gas generated after burning can be entered in flue, in exhaust gas from being expelled in quirk and sinking in inner cooking stove by exhaust gases passes During discharge, the air in air intake duct constantly absorbs the heat in exhaust gas during entering to premixer, with The temperature of air is improved, realization can make full use of heat in exhaust gases after combustion, improve heat utilization ratio, improves combustion gas and utilizes Rate.

2, the premixer is equipped with protruding portion, and the protruding portion and outer cooking stove are adapted, and can prevent premixer from making Occurs rotation phenomenon during, while the combustion gas entered can be mixed well with air in protruding portion, can guarantee combustion gas It being capable of full combustion.

3, the part that the air intake duct is located in flue is parallel with flue inner wall, air intake duct can be made in cigarette It is in an intermediate position in road, so that the air in air intake duct is further fully absorbed the heat in exhaust gas.

4, the air intake duct is located at the portions end in flue equipped with blower, and the blower can constantly press air Enter in air intake duct, prevents combustion gas from leaking out by air intake duct, ensure that there are enough air in premixer to guarantee Combustion gas full combustion further improves combustion gas utilization rate.

5, the outer cooking stove top is 5-8cm higher than inner cooking stove top, can guarantee during the cooking process, to prevent the bottom of a pan internal Stove, which is formed, to be squeezed, and the exhaust gas that generates cannot be discharged in time after avoiding burning, ensure that gas-cooker in use steady It is qualitative.

6, the air intake duct is two or more pieces, and the air inlet pipe is parallel, and the air intake duct can guarantee The heat in exhaust gas is fully absorbed, while can also ensure that and provide enough air for premixer.

7, fire-resistant ring is equipped with inside the inner cooking stove, the discharge tube end is equipped with arc gaseous mixture spout, the arc Gaseous mixture spout is matched with fire-resistant ring, and the mixed combustion gas being discharged from premixer is entered to interior by arc gaseous mixture spout It burns in stove, the fire-resistant ring forms barrier effect to mixed combustion gas to be made to produce so that it be made to scatter along fire-resistant ring Raw flame disperses along fire-resistant ring, to guarantee that the bottom of a pan is heated evenly.
