The energy collecting ring 200 is disposed around the combustion portion 100, and after the gas in the combustion portion 100 is combusted to form flame in the combustion portion 100, the energy collecting ring 200 disposed around the combustion portion 100 can be heated, so that the energy collecting ring 200 is heated. The energy collecting ring 200 is provided with a preheating hole 210 and a preheating channel 220, the preheating channel 220 of the energy collecting ring 200 is communicated with the preheating hole 210 and the air channel of the combustion part 100, and external air can enter the preheating channel 220 of the energy collecting ring 200 through the preheating hole 210 of the energy collecting ring 200 and then enter the air channel of the combustion part 100, so that the aim of supplementing secondary air to the combustion part 100 is fulfilled. Specifically, the preheating passage 220 of the energy accumulating ring 200 communicates through the air port of the combustion section 100, thereby causing the preheating passage 220 to communicate with the air passage of the combustion section 100.

The energy collecting ring 200 can be heated to raise the temperature of the energy collecting ring 200, and correspondingly, the air entering the preheating channel 220 of the energy collecting ring 200 can exchange heat with the energy collecting ring 200, so that the secondary air is heated, and the heated secondary air is supplemented to the combustion part 100 to enable the temperature of the gas in the gas mixing cavity of the combustion part 100 to be higher after being combusted, so that the combustion effect of the gas stove is better.

When the secondary air enters the preheating passage 220 of the energy accumulating ring 200, the energy accumulating ring 200 can serve the purpose of protecting the secondary air, specifically, the secondary air can be not influenced by the air flow outside the energy accumulating ring 200 after the secondary air enters the preheating passage 220 of the energy accumulating ring 200, so that the flow rate and the flow velocity of the secondary air in the preheating passage 220 of the energy accumulating ring 200 can be kept stable. The air passage of the combustion portion 100 is also located in the combustion portion 100, so that after the secondary air enters the air passage of the combustion portion 100 from the preheating passage 220 of the energy collecting ring 200, the secondary air can be protected by the combustion portion 100, so that the flow rate and the flow velocity of the secondary air can be kept stable, and thus the flow rate and the flow velocity of the secondary air supplemented by the fuel gas output to the gas mixing chamber of the combustion portion 100 are stable, and finally the combustion effect of the fuel gas output from the gas mixing chamber of the combustion portion 100 can be kept stable.

In the gas stove disclosed in the embodiment of the application, the air channel that sets up in the combustion part 100 communicates with the air mixing chamber, and the air channel still communicates with the preheating channel 220 of gathering the ability ring 200, and the outside air of gas stove accessible gathers the preheating hole 210 of ability ring 200 and gets into preheating channel, in the air channel and the air mixing chamber in proper order to the gas of air mixing chamber output supplements oxygen, and then promotes the secondary air of the gas stove of this application and supplements efficiency. The energy gathering ring 200 encloses and locates the combustion portion, can heat the energy gathering ring 200 after the gas combustion in the combustion portion and make the energy gathering ring 200 temperature rise, therefore can be heated through the air in the preheating channel 220 of energy gathering ring 200, can reach the purpose of preheating the secondary air like this for the secondary air can make the temperature of gas combustion higher after supplementary combustion portion, thereby makes the heating effect of the gas-cooker of this application better.

In some embodiments, in order to make the energy-collecting ring 200 of the present application have a better energy-collecting and heat-insulating effect, the energy-collecting ring 200 may further be provided with a heat-insulating cavity 230, and the heat-insulating cavity 230 may also serve to insulate heat and reduce the heat emitted from the energy-collecting ring 200, so that the energy-collecting ring 200 may have a multi-layer cavity structure to have a better energy-collecting effect.

In some embodiments, in order to make the air outside the gas range supplement the secondary air to the combustion part 100 more efficiently, the gas range of the present application may further be provided with a blower 300, and the blower 300 may input the air outside the gas range into the first sub-channel 113 and the second sub-channel 114 through the first air holes 1131 and the second air holes 1141 of the combustion part 100.

The first sub-channel 113 in the combustion portion 100 may be disposed between the first cavity 111 and the second cavity 112, and thus, the second cavity 112 may be disposed around the first cavity 111 at a distance, so that a space is provided between the first cavity 111 and the second cavity 112 to dispose the first sub-channel 113. After the first sub-channel 113 is disposed between the first cavity 111 and the second cavity 112, the first sub-channel 113 can be disposed adjacent to the first cavity 111 and the second cavity 112 at the same time, so that the space between the first sub-channel 113 and the first cavity 111 and the space between the first sub-channel 113 and the second cavity 112 are relatively smaller, and air in the first sub-channel 113 can reach the first cavity 111 after flowing through a shorter stroke, so that the secondary air supply efficiency of the gas stove is higher.

In the case that the first sub-channel 113 of the combustion portion 100 is enclosed in the first cavity 111 and is enclosed by the second cavity 112, in order to make the air in the first sub-channel 113 be more efficiently input into the first cavity 111 and the second cavity 112, the first air outlet 1132 and the second air outlet 1133 of the first sub-channel 113 may be provided in a plurality, and the plurality of first air outlets 1132 and the plurality of second air outlets 1133 are all distributed along the circumference of the first sub-channel 113, so that the air in the first sub-channel 113 may be input into the first cavity 111 and the second cavity 112 from a plurality of directions.

Of course, it should be understood that, in other embodiments, the first air guiding cover 140 and the side walls of the burner 110 and the outer fire cover 130 of the present application may be arranged to form the first sub-channel 113 together, and specifically, the side of the first air guiding cover 140 facing the outer fire cover 130 does not need to be additionally provided with a cover structure, so that the inner side wall of the outer fire cover 130 may be used as the inner wall of the first sub-channel 113, thereby achieving the purpose of saving the material of the first air guiding cover 140. Of course, it should be noted that, in the above-mentioned arrangement structure of the first induced draft cover 140, the outer fire hole 131 of the outer fire cover 130 may be disposed on the sidewall of the outer fire cover 130 facing away from the first induced draft cover 140, so that when the inner sidewall of the outer fire cover 130 is used as the inner wall of the first sub-channel 113, the first induced draft cover 140 does not enclose the outer fire hole 131 of the outer fire cover 130 therein, so that the mixed gas exhausted from the outer fire hole 131 of the outer fire cover 130 can be combusted smoothly.

In addition, in other embodiments, the first air guiding cover 140 of the present application may be further configured as a cover plate that is erected between the outer fire cover 130 and the inner fire cover 120, so that the first air guiding cover 140, the outer side wall of the inner fire cover 120, the inner side wall of the outer fire cover 130 and the burner 110 together enclose to form the first sub-channel 113, which can save the materials of the first air guiding cover 140 to the greatest extent.

In some embodiments, in order to enable the first sub-channel 113 in the combustion portion 100 of the present application to communicate with the first cavity 111, the first induced draft cover 140 of the present application may be configured to cover at least a portion of the inner fire cover 120, specifically, an inner top wall of the first induced draft cover 140 is disposed opposite to a top of the inner fire cover 120, and the inner top wall of the first induced draft cover 140 and the top of the inner fire cover 120 have a certain gap, which may form the first air outlet 1132, air located in the first induced draft channel 410 may be exhausted out of the first induced draft channel 410 through the first air outlet 1132, and since an opening of the first air outlet 1132 faces to one side of the inner fire cover 120, air exhausted through the first air outlet 1132 of the first induced draft channel 410 may act on the inner fire cover 120 to supplement secondary air for flame burned at the inner fire cover 120.

By disposing the first air outlet 1132 at the portion of the first induced-draft cover 140 covered by the inner fire cover 120 and positioning the first air outlet 1132 between the first induced-draft cover 140 and the inner fire cover 120, the first induced-draft cover 140 does not need to be additionally and separately provided with the first air outlet 1132. The air exhausted through the first air outlet 1132 may flow along the outer sidewall of the inner fire cover 120 under the effect of the coanda effect, and since the inner fire hole 121 of the inner fire cover 120 is opened at the surface of the inner fire cover 120, the air flowing along the outer wall of the inner fire cover 120 may more easily flow to the position of the inner fire hole 121 of the inner fire cover 120, so that the air exhausted through the first air outlet 1132 may be better supplemented to the inner fire cover 120, so that the fire power of the flame generated at the inner fire cover 120 may be more sufficient.

In addition, it should be understood that, after the gap between the first induced-draft cover 140 and the inner fire cover 120 forms the first air outlet 1132, in order to make the opening of the first air outlet 1132 larger, the circumferential bottom wall of the first induced-draft cover 140 and the circumferential top wall of the inner fire cover 120 may be provided with gaps, and the intervals of the gaps remain consistent, so that the first air outlet 1132 may be distributed along the circumferential direction of the first induced-draft cover 140, and the openings of each part of the first air outlet 1132 in the circumferential direction of the first induced-draft cover 140 are consistent in size, thereby achieving the purpose of uniformly supplementing secondary air to each part of the circumferential direction of the inner fire cover 120.

In some embodiments, in order to make the first sub-channel 113 of the present application communicable with the second cavity 112, the second air outlet 1133 may be opened on a side wall of the first induced draft cover 140 facing the outer fire cover 130 under the condition that the first induced draft cover 140 encloses the inner fire cover 120 and the first induced draft cover 140 is enclosed by the outer fire cover 130, so that an opening of the second air outlet 1133 may face the outer fire cover 130, and since the outer fire cover 130 encloses the first induced draft cover 140 at intervals, secondary air in the first sub-channel 113 of the combustion portion 100 may flow to the outer fire cover 130 through the second air outlet 1133 on the first induced draft cover 140. Since the outer fire cover 130 is provided with the outer fire holes 131, the secondary air flowing to the outer fire cover 130 through the first sub-channel 113 of the combustion part 100 can supplement air to the flame generated by the outer fire cover 130, so that the flame force of the flame at the outer fire cover 130 is stronger.

It should be understood that the mixed gas in the second cavity 112 of the combustion part 100 of the present application may be injected through the fire hole of the outer fire cover 130, so when the secondary air in the first sub-passage 113 may directly supplement the secondary air to the outer fire hole 131 of the outer fire cover 130, the gas in the second cavity 112 of the combustion part 100 may be combusted more fully. Specifically, the outer fire hole 131 of the outer fire cover 130 may be disposed on the side wall of the outer fire cover 130 facing the first induced air cover 140, so that the second air outlet 1133 of the first induced air cover 140 and the outer fire hole 131 of the outer fire cover 130 are disposed opposite to each other, thereby achieving the purpose of reducing the distance between the second air outlet 1133 of the first induced air cover 140 and the outer fire hole 131 of the outer fire cover 130, and further enabling the secondary air discharged through the second air outlet 1133 of the first induced air cover 140 to reach the outer fire hole 131 of the outer fire cover 130 more rapidly. The number of the second air outlets 1133 on the first induced-draft cover 140 may be plural, and the plurality of second air outlets 1133 may be disposed to be spaced along the circumferential direction of the first induced-draft cover 140.

In addition, it should be noted that the fuel gas in the second cavity 112 of the combustion part 100 is ignited after being discharged through the outer flame holes 131 of the outer flame cover 130, so that in order to make the combustion-supporting effect of the secondary air on the flames at the outer flame cover 130 better, it can be achieved by supplementing the secondary air to the root of the flames at the outer flame cover 130, the position of the outer flame holes 131 of the outer flame cover 130 is the root position of the flames at the outer flame cover 130.

In this application, the second air outlet 1133 of the first induced cover 140 may be set to a height not higher than the outer flame hole 131 of the outer flame cover 130, so that secondary air discharged through the second air outlet 1133 of the first induced cover 140 may be supplemented to the outer flame hole 131 of the outer flame cover 130, and further the secondary air may be supplemented to the flame root at the outer flame cover 130.

Specifically, the second air outlet 1133 of the first induced draft cover 140 of the present application may form a projection area on the outer fire cover 130 in a direction towards the outer fire cover 130, and the projection area of the outer fire cover 130 is more adjacent to the burner 110 relative to the outer fire hole 131 on the outer fire cover 130, so that the height of the second air outlet 1133 of the first induced draft cover 140 is lower than the outer fire hole 131 of the outer fire cover 130. When the secondary air is discharged from the second air outlet 1133 of the first induced cover 140, the initial position of the secondary air flow is lower than the outer fire hole 131 of the outer fire cover 130, and the temperature of the secondary air is increased due to the high temperature during operation of the gas range, so that the secondary air flow can naturally rise. In addition, since the air outlet of the first induced draft cover 140 faces the outer flame cover 130, the secondary air discharged through the second air outlet 1133 of the first induced draft cover 140 has a velocity flowing toward the outer flame cover 130 and a naturally rising velocity, so that the secondary air discharged through the second air outlet 1133 of the first induced draft cover 140 can flow toward the outer flame holes 131 of the outer flame cover 130, thereby supplementing the root of the flame generated by the outer flame cover 130 with the secondary air.

In some embodiments, the combustion portion 100 of the present application may further include a second air induction cover 150, where the second air induction cover 150 is also disposed on the burner 110, and the second air induction cover 150 and the burner 110 enclose to form the second sub-channel 114. Specifically, the second induced draft cover 150 may be configured to enclose the outer fire cover 130, such that the second sub-channel 114 is located outside the second cavity 112.

The second sub-channel 114 is communicated with the second cavity 112, and the fan 300 can also introduce air outside the gas stove into the second sub-channel 114 and supplement the air to the second cavity 112, so that the gas in the second cavity 112 can be further combusted sufficiently.

In addition, in order to reduce the preparation difficulty of the second induced draft cover 150 and save the material of the second induced draft cover 150, after the second induced draft cover 150 is disposed on the burner 110, the second induced draft cover 150, the burner 110 and the side wall of the outer fire cover 130 are enclosed together to form the second sub-channel 114, specifically, the side of the second induced draft cover 150 facing the outer fire cover 130 does not need to be additionally provided with a cover structure, so that the outer side wall of the outer fire cover 130 can be used as the inner wall of the second sub-channel 114, thereby achieving the purpose of saving the material of the second induced draft cover 150. Of course, it should be noted that, in the above-mentioned arrangement structure of the second induced draft cover 150, the outer fire hole 131 of the outer fire cover 130 should be disposed outside the second sub-channel 114, so that when the outer sidewall of the outer fire cover 130 is used as the inner wall of the second sub-channel 114, the second induced draft cover 150 does not enclose the outer fire hole 131 of the outer fire cover 130 inside, so that the mixed gas exhausted from the outer fire hole 131 of the outer fire cover 130 can be burned smoothly. Specifically, the outer fire hole 131 may be disposed on a side wall of the outer fire cover 130 facing away from the second induced draft cover 150.

By disposing the third air outlet 1142 at the portion of the second air guiding cover 150 covering the outer fire cover 130, and positioning the third air outlet 1142 between the second air guiding cover 150 and the outer fire cover 130, it is unnecessary to separately provide the third air outlet 1142 on the second air guiding cover 150. The air discharged through the third air outlet 1142 may flow along the outer sidewall of the outer fire cover 130 under the effect of the coanda effect, and since the outer fire hole 131 of the outer fire cover 130 is opened on the surface of the outer fire cover 130, the air flowing along the outer wall of the outer fire cover 130 may more easily flow to the position of the outer fire hole 131 of the outer fire cover 130, so that the air discharged through the third air outlet 1142 may be better supplemented to the outer fire cover 130, so that the fire power of the flame generated at the outer fire cover 130 may be more sufficient.

In addition, it should be understood that, after the gap between the second induced-draft cover 150 and the outer fire cover 130 forms the third air outlet 1142, in order to make the opening of the third air outlet 1142 larger, the circumferential bottom wall of the second induced-draft cover 150 and the circumferential top wall of the outer fire cover 130 may be provided with gaps, and the intervals of the gaps remain consistent, so that the third air outlet 1142 may be distributed along the circumferential direction of the second induced-draft cover 150, and the openings of each portion of the third air outlet 1142 in the circumferential direction of the second induced-draft cover 150 are consistent, so as to achieve the purpose of uniformly supplementing secondary air to each portion of the circumferential direction of the outer fire cover 130.

In this application, since the second induced air cover 150 encloses the outer fire cover 130, a certain gap is formed between the second induced air cover 150 and the outer fire cover 130, the second air hole 1141 may be disposed on one side of the bottom of the second induced air cover 150, the second air hole 1141 is communicated with the second sub-channel 140 of the combustion portion 100, and the second air hole 1141 is further communicated with the preheating channel 220 of the energy collecting ring 200, so that secondary air in the preset channel 220 may be supplemented to the second sub-channel 114 through the second air hole 1141, and further supplemented into the second cavity 112.

In some embodiments, in order to further make the gas injected from the inner fire hole 121 of the inner fire cover 120 burn fully, the inner fire cover 120 of the present application may be configured as a hollow structural member, so that the third sub-channel 115 may be formed on the inner side of the inner fire cover 120, and the blower 300 may be configured to input air into the third sub-channel 115, so that secondary air may be supplemented into the third sub-channel 115, thereby achieving the purpose of supplementing secondary air to the inner fire hole 121 of the inner fire cover 120, and finally making the gas injected from the inner fire hole 121 burn fully.

Accordingly, the third air hole 1151 of the third sub-channel 115 may also be disposed on the burner 110, and located on a side of the burner 110 facing away from the second air guiding cover 150.
