Description
Technical field
The utility model belongs to power-saving technology and equipment field, is related to a kind of auxiliary energy-saving cover of gas appliance.
Background technology
Existing kitchen gas kitchen range use open Nonpremixed flames mostly, and flame is heating pot and stove simultaneously, also with higher
Temperature the heat energy of preciousness is radiated into air, therefore cause the thermal efficiency of gas appliance very low（Generally below 30%）, while
So that operating environment is deteriorated.Also some patented technologies improve conventional kitchen range, but also there is problems with：1）Institute
The improved method structure of use is partially complicated, is unfavorable for manufacturing, and influences to promote the use of.2）Energy-saving effect is general, is far from reaching reason
The degree thought.3）Manufacturing cost is high, is unfavorable for promoting.To solve problem above, the utility model proposes a kind of new folder
Laminar aids in eddy flow energy-saving hood for gas stove.
Utility model content
The purpose of this utility model is to provide a kind of sandwich-type auxiliary eddy flow energy-saving hood for gas stove, can use simpler structure
And lower cost, the waste heat of flue gas is as much as possible recycled, and burnt by rotating torch type, enhance fuel and sky
The mixing of gas, the efficiency of combustion of gas range is greatly improved, and then improves gas utilization rate, and improve the operation ring in kitchen
Border, so as to solve problems of the prior art.
Technical scheme is used by the utility model：
A kind of sandwich-type aids in eddy flow energy-saving hood for gas stove, is made up of outer cover and inner cover, and the outer cover is hollow cylinder, its
External diameter is equal with inner cover outer most edge diameter, and indentation is opened up at the top of outer cover, and interior cage is covered outside, forms some air intakes
Hole；Inner cover is curved-surface structure of the up big and down small section for circle, and along the circumferential direction uniform some bossings are formed at its top
Support feet, the part beyond support feet contacts with pan form exhanst gas outlet.
Further, the equidistant uniform some swirl vanes in the inner cover circumferential direction inside direction.
Further, the swirl vane arrangement 3-10 pieces.
The beneficial effects of the utility model are：
The utility model is using cover top intake method（Refer to air）, cold air is inside and outside the fresh air inlet entrance on energy-saving cover top
Flow in the interlayer of cover and from top to bottom, while heated and heated up so as to reduce air/gas mixture by the inner cover of high temperature
Ignition heat, be advantageous to catching fire and burning for fresh fuel；Air after heating is in cover bottom and combustion gas combination after-combustion, caused cigarette
Gas, which rises to inner cover porch and produced through swirl vane water conservancy diversion, rotates and then strengthens combustion gas and the mixing of air and disturbance, so as to strong
Combustion process is changed so that burning is rapid and complete, and the efficiency of combustion of cooking stove is greatly improved.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Sandwich-type auxiliary eddy flow energy-saving hood for gas stove of the present utility model is made up of outer cover 1 and inner cover 2, and outer cover 1 is certain thick
The hollow cylinder of degree, its external diameter is equal with inner cover outer most edge diameter, and a number of indentation is opened up at the top of outer cover
1.1, in use, the frame of inner cover 2 on outer cover 1, can form some square holes, this square hole is fresh air inlet.Inner cover 2 is up big and down small
Section be circular curved-surface structure, along the circumferential direction uniform some bossings form support feets 2.1 at its top, can typically set
Only, to support pan, and the part in addition to support feet contacts with pan then forms slit to 4-12, and the slit is flue gas
Outlet.The equidistant uniform some swirl vanes 2.2 in inner cover circumferential direction inside direction, can typically arrange 3-10 pieces.
After air enters the annular air passage 3 in inside and outside cover gap by fresh air inlet, top-down flowing is simultaneously high
The inner cover 2 of temperature is heated into the hot-air with certain temperature, and this will reduce the ignition heat of air-gas mixture, so as to favourable
In catching fire and burn；Air after heating rises to inner cover entrance in inner cover bottom and combustion gas combination after-combustion, caused flue gas
Produced by the water conservancy diversion of swirl vane 2.2 and rotate and then strengthen combustion gas and the mixing of air and disturbance, so as to enhance combustion process,
So that burning is rapid and complete, the efficiency of combustion of cooking stove is greatly improved.Flue gas with pan and by inner cover surface and
Cold air reduces temperature after carrying out heat exchange, is then discharged into ring by gap caused by non-contact part at the top of pan and inner cover
In border.
