[0031] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-8 , the present invention provides a cooking appliance for improving gas utilization efficiency, including a cooking appliance body 1. A blowing device 2 and a premixing component 3 are arranged in the cooking appliance body 1. A rotating ring assembly 4 is arranged in the premixing component 3. A plurality of booster valve cavity assemblies 5 are arranged on the rotating ring assembly 4. A gas input end 6 and a mixed gas output end 7 are respectively arranged on the left and right sides of the premixing component 3. An outer communication component 8 for connecting the gas input end 6 or the mixed gas output end 7 is arranged outside the booster valve cavity assembly 5. An air input component 9 is fixedly arranged in the middle of the rotating ring assembly 4. An inner communication component 10 capable of connecting the air input component 9 is arranged inside the booster valve cavity assembly 5. A mixing and stirring device 11 is arranged in the booster valve cavity assembly 5. An automatic rotation transmission component 12 for driving the mixing and stirring device 11 to rotate automatically during the rotation of the rotating ring assembly 4 is arranged between the mixing and stirring device 11 and the premixing component 3. The mixed gas output end 7 is connected to the cooking appliance body 1;

[0033] The outer communication component 8 is communicatively connected to a corresponding one of the booster valve cavity assemblies 5;

[0034] The inner communication component 10 is communicatively connected to one corresponding supercharging valve cavity component 5;

[0035] Rotating ring assembly 4: The drive motor 405 is installed on the motor mounting base 404, and the output end of the motor is fixedly connected to the lower end surface of the rotating ring body 402. When the drive motor 405 is started, it drives the rotating ring body 402 to perform a circular motion within the circular slot 401 of the premixing component 3. The rotation of the rotating ring body 402 enables each supercharging valve cavity component 5 to be sequentially communicated with the gas input end 6, the air input end 903, and the mixed gas output end 7, realizing periodic gas input, mixing, and output.

[0036] Gas and air input process

[0037] Gas input: When the rotating ring body 402 rotates continuously, one of the outer arc slots 801 covers the gas input end 6. At this time, the gas input end 6 is communicated with the premixing chamber 501 through the corresponding gas transmission communication hole 802, and the external gas enters the premixing chamber 501 through the gas input end 6 and the gas transmission communication hole 802 under the action of pressure. The outer partition 803 ensures that the gas between adjacent outer arc slots 801 does not interfere with each other, ensuring the accuracy of gas input;

[0038] Air input: The rotation of the rotating ring body 402 causes the air input end 903 to be communicated with the premixing chamber 501 through the air connection hole 102, and air also enters the premixing chamber 501. The inner partition 103 plays a similar role to the outer partition 803, ensuring the orderliness of air input.

[0039] At this time, the same premixing chamber 501 is simultaneously connected to the air input end 903 and the gas input end 6, causing internal inflation and pressurization;

[0040] Supercharging valve cavity component 5: The premixing chamber 501 is a place where gas and air are mixed. The elastic shrinkable airbag 503 at its bottom is connected to the premixing chamber 501 through the airbag connection opening 502. The elastic shrinkable airbag 503 is made of fluororubber material combined with carbon fiber material, having good elasticity and durability. When gas enters the premixing chamber 501, the airbag can contract or expand according to the pressure change in the chamber, and the expansion process can increase the pressure between air and gas molecules, helping to enhance the mixing effect of the gas.

[0041] When one of the premixing chambers 501 is simultaneously docked at the positions of the air input end 903 and the gas input end 6, gas and air simultaneously enter the premixing chamber 501. At this time, the elastic shrinkable airbag 503 gradually expands to increase the space and raise the internal pressure;

[0042] When one of the pre-mixing chambers 501 is connected to the position of the mixed gas output end 7, at this time, the air input end 903 and the gas input end 6 are in a closed state. Under the action of the elastic contraction airbag 503's rebound pressure, the space decreases and contracts, causing the internal mixed gas to be discharged from the mixed gas output end 7 into the cooker for combustion.

[0043] Mixing and stirring device 11 and self-rotation transmission component 12: The stirring rotating shaft 112 is installed in the rotating shaft hole 111 on the upper end surface of the pre-mixing chamber 501, and the disk turbine type stirring paddle assembly 113 at the lower end is located inside the pre-mixing chamber 501. The transmission gear 122 at the upper end of the stirring rotating shaft 112 meshes with the fixed internal gear 121 on the pre-mixing component 3. When the rotating ring body 402 rotates, it drives the stirring rotating shaft 112 to revolve around the center of the rotating ring body 402. At the same time, due to the meshing of the transmission gear 122 and the fixed internal gear 121, the stirring rotating shaft 112 will rotate self, thereby enabling the disk turbine type stirring paddle assembly 113 to stir the gas and air inside the pre-mixing chamber 501 and promoting their full mixing.

[0044] Mixed gas output: During the continuous rotation of the rotating ring body 402, when the outer arc slot 801 corresponding to a certain pre-mixing chamber 501 covers the mixed gas output end 7, the mixed gas flows out from the mixed gas output end 7 through the gas transmission communication hole 802 and the outer arc slot 801 and enters the cooker body 1 for combustion. Since the mixed gas has been fully mixed inside the pre-mixing chamber 501, it can burn more fully after entering the cooker body, thereby improving the utilization rate of the gas.

[0045] A plurality of inner arc slots 101 and a plurality of outer arc slots 801 are arranged closely, basically covering the inner and outer walls of the circumference of the rotating ring body 402, improving its continuous connection with the corresponding mixed gas output end 7, air input end 903 and the gas input end 6, and further ensuring the stability of gas combustion.

[0046] The rotating ring assembly 4 of the present invention includes a circular slot 401 provided on the pre-mixing component 3. A rotating ring body 402 is rotatably arranged in the circular slot 401. An airbag protection frame 403 is provided at the lower end of the pre-mixing component 3. A motor mounting seat 404 is provided on the airbag protection frame 403. A driving motor 405 is provided in the motor mounting seat 404. The output end of the driving motor 405 is fixedly connected to the lower end surface of the rotating ring body 402.

[0055] During the continuous rotation of the rotating ring body 402 of the present invention, one of the outer arc slots 801 will cover the gas input end 6, so that the gas input end 6 is communicated with a corresponding air transmission connection hole 802, and external gas enters into a corresponding premixing chamber 501;
