In view of the above, referring to fig. 1-3, the pot rack 10 includes a pot rack body 11 and a power device 124.

The pot holder body 11 is annularly arranged and enclosed to form a combustion chamber 11a, and the pot holder body 11 is also provided with a jet flow channel 11c and an air supplementing channel 11d.

The jet port 11c3 of the jet channel 11c is located on the upper surface 111a or the outer circumferential surface of the pot holder 10, and is used for providing air flow in a direction approaching to the cooker, so that flue gas between the pot holder body 11 and the cooker can be gathered in a direction approaching to the cooker, and the contact time between the flue gas and the bottom of the cooker can be increased, so that heat of the flue gas is conducted to the bottom of the cooker more, and the heat efficiency of the gas stove 1 is improved.

The air supplementing port 11d3 of the air supplementing channel 11d is communicated with the combustion chamber 11a, so that secondary air can be supplemented to the combustion chamber 11a through the air supplementing port 11d3, the air content in the combustion chamber 11a can be improved, additional oxygen can be provided for combustion, more complete combustion of fuel is promoted, and the thermal efficiency of the fuel is further improved, so that the overall thermal efficiency of the gas stove 1 is further improved.

And because the fuel can be fully combusted, the generation of incomplete combustion products such as carbon monoxide, hydrocarbon and the like can be reduced, so that the generation of residues such as unburnt carbon particles (black smoke) and tar and the like can be reduced, the PM2.5/PM10 emission can be reduced, and the air quality can be improved. Further, the generation of unburned carbon particles (black smoke), tar and other residues can be reduced, so that the probability of blocking the burner 20, the flue and other parts by the residues can be reduced, the equipment maintenance period is prolonged, the maintenance cost of a user is reduced, and the use experience of the user is improved.

The power device 124 is in communication with both the jet channel 11c and the air supplementing channel 11d, and is configured to provide air flow to the jet channel 11c and the air supplementing channel 11 d. It is appreciated that the power plant 124 includes at least one of an air pump, a fan, and a jet generator 1242. In other embodiments, the power device 124 may take other forms. In the embodiment of the present application, the specific form of the power unit 124 is not limited.

In the embodiment of the application, the power device 124 provides air flow to the jet flow channel 11c and the air supplementing channel 11d, and provides air flow to the direction close to the cooker through the jet port 11c3 of the jet flow channel 11c, so that flue gas between the pot rack body 11 and the cooker can be gathered to the direction close to the cooker, the contact time between the flue gas and the bottom of the cooker can be increased, so that the heat of the flue gas is conducted to the bottom of the cooker more, the heat efficiency of the gas cooker 1 is improved, further, the air supplementing port 11d3 of the air supplementing channel 11d is communicated with the combustion chamber 11a, secondary air can be supplemented to the combustion chamber 11a through the air supplementing port 11d3, the air content in the combustion chamber 11a can be improved, additional oxygen can be provided for combustion, the fuel can be more fully combusted is promoted, the heat efficiency of the fuel is further improved, and the heat efficiency of the whole gas cooker 1 is further improved.

Referring to fig. 1-3, in an embodiment, a side of the pot rack body 11 facing away from the cavity of the combustion chamber 11a is an outer side, and a central axis of the jet port 11c3 is inclined from bottom to top to the outer side, so that an air flow ejected from the jet port 11c3 can impact a flue gas between the pot rack body 11 and a cooker at a specific angle. The inclined jet flow mode can guide the flue gas to diffuse upwards and outwards in a fan shape, so that the bottom of the cooker is covered more comprehensively and uniformly, the contact area between the flue gas and the bottom of the cooker is greatly increased, the heat conduction efficiency is remarkably improved, and the heat efficiency of the gas stove 1 is further improved.

Referring to fig. 1-3, in one embodiment, the included angle α between the central axis of the jet 11c3 and the axial direction of the combustion chamber 11a is 0≤α≤60 °.

Referring to fig. 3, if α=0°, at this time, the central axis of the jet 11c3 is axially parallel to the combustion chamber 11a, and the air flow ejected from the jet 11c3 vertically impacts the bottom of the cooker, so as to precisely act on the smoke under the cooker, and promote the smoke to directly contact with the bottom of the cooker, thereby increasing the contact time between the smoke and the bottom of the cooker and improving the heat conduction efficiency. The gas stove is particularly suitable for cookers with flat bottoms and diameters matched with the combustion cavity 11a, heat can be uniformly and rapidly transferred to the cookers, heat dissipation to the surrounding environment is reduced, and the heat efficiency of the gas stove 1 is improved.

And because the air flow sprayed out of the jet port 11c3 vertically impacts the bottom of the cooker, the air flow in the combustion chamber 11a is less disturbed, and the stability of the air flow in the combustion chamber 11a can be maintained. The stable air flow environment provides favorable conditions for full combustion of fuel, reduces incomplete combustion caused by air flow disturbance, reduces emission of pollutants such as carbon monoxide and the like, simultaneously keeps stable flame, and ensures safety and high efficiency of the cooking process.

If 0 ° < α <60 °, along with the increase of α, the airflow ejected from the jet 11c3 impacts the smoke between the pot frame body 11 and the cooker at an inclined angle, so as to guide the smoke to spread outward in a fan shape, thereby greatly increasing the contact area between the smoke and the bottom of the cooker, and further improving the thermal efficiency of the gas stove 1. In addition, the inclined jet flow forms a specific aerodynamic field above the combustion chamber 11a, so that fresh air outside the combustion chamber 11a is driven to be involved in, and the fresh air is more fully mixed with high-temperature flue gas and fuel in the combustion chamber 11a, so that the combustion efficiency is improved, and the pollutant emission is reduced.

And the above angle range can be better adapted to cookware of different shapes and sizes.

It is understood that the upper surface 111a of the upper cover 111 has the jet port 11c3. In other embodiments, the outer sidewall of the middle layer cover 112 has jet ports 11c3.

It is understood that the outer side wall of the lower cover 113 has the jet port 11c3. In other embodiments, jet port 11c3 can also be defined by the outer edge of middle layer cover 112 and the top edge of lower layer cover 113.
