[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Embodiment 1

[0036] Please refer to Figure 1 to Figure 6 The embodiment of the present application discloses a combustion device, including a panel 100, a combustion part 200, an injection part 300 and a blast part 400. The combustion device can be applied to kitchen heating equipment such as a gas stove.

[0037] It should be understood that a combustion device is a device that generates flames by burning fuel gas. The fuel gas is introduced into the combustion device, and the fuel gas is mixed with air to form a mixed gas. When the mixed gas is ignited, a flame can be formed. Therefore, the combustion device needs to be connected to a gas pipeline to input fuel gas into the combustion device, and the combustion device also needs to have an air port for allowing air to enter, so that the air can be mixed with the fuel gas to form a mixed gas.

[0038] Among them, the panel 100 is the basic component of the combustion device of the present application. The panel 100 can provide an installation basis for at least some other components of the combustion device. The combustion part 200, the injection part 300 and the blowing part 400 are all arranged on the panel 100. The various components of the combustion device can be fixedly connected to the panel 100, so that the structure of the combustion device of the present application is stable.

[0039] The combustion part 200 is provided with a gas path, and the mixed gas formed by the mixture of fuel gas and air can enter the combustion part 200 and be distributed in the gas path of the combustion part 200. The mixed gas in the gas path of the combustion part 200 is ignited to form a flame. Of course, the fuel gas can also be directly injected into the combustion part 200, so that the fuel gas is mixed with the air during the process of being distributed in the gas path of the combustion part 200, so that the purpose of mixing the fuel gas with the air can also be achieved.

[0040] The ejector 300 is a gas supply mechanism of the combustion device. The ejector 300 can be arranged to be connected to a gas pipeline, and the gas pipeline can input the fuel gas into the ejector 300. The ejector 300 is connected to the combustion part 200. After the fuel gas enters the ejector 300, it can finally enter the combustion part 200. The ejector 300 is provided with a primary air port 310. The air outside the combustion device can enter the ejector 300 through the primary air port 310, so that the fuel gas and air in the ejector 300 are mixed to form a mixed gas. The air in the mixed gas allows the fuel gas to be in an oxygen-rich environment. After the mixed gas is input into the combustion part 200, the mixed gas in the combustion part 200 is ignited by the ignition mechanism of the combustion device to form a flame.

[0041] Specifically, the ejection part 300 has a gas channel, and the two ends of the gas channel are connected to the gas pipeline and the combustion part 200 respectively. The fuel gas input into the ejection part 300 by the gas pipeline is located in the gas channel, and the primary air port 310 of the ejection part 300 is connected to the gas channel in the ejection part 300. The fuel gas input into the ejection part 300 by the gas pipeline has a faster flow rate in the process of passing through the gas channel, so this part of the fuel gas can eject the external air into the gas channel of the ejection part 300 through the primary air port 310, so that the fuel air is mixed with the external air. The mixed gas can still maintain a faster flow rate in the process of passing through the gas channel of the ejection part 300, so that the mixed gas can enter the combustion part 200 and be distributed in the gas path of the combustion part 200, so that the mixed gas is evenly diffused in the combustion part 200.

[0042] The panel 100 described above has a first side 110 and a second side 120 opposite to each other, the combustion part 200 is arranged on the first side 110 of the panel 100, and the primary air port 310 of the ejection part 300 is also arranged on the first side 110 of the panel 100. Specifically, the panel 100 is arranged on the side of the combustion part 200 facing away from the combustion side of the combustion part 200, the flame formed by the mixed gas in the combustion part 200 after ignition is located on the combustion side of the combustion part 200, and the heated part, such as a pot, is mounted on the combustion side of the combustion part 200. During the use of the combustion device, the oily impurities such as soup overflowed from the pot placed on the combustion side of the combustion part 200 can fall onto the panel 100, so the panel 100 can collect the soup oily impurities to prevent the soup oily impurities from spreading everywhere, and the soup oily impurities are concentrated on the panel 100 and are easier to clean.

[0043] The primary air port 310 of the ejection part 300 is also arranged on the first side 110 of the panel 100. The primary air port 310 and the combustion part 200 are located on the same side of the panel 100. This makes the combustion device of the present application an upper air intake structure. The external air located on the first side 110 of the panel 100 can enter the ejection part 300 through the primary air port 310, so that the fuel gas and air in the ejection part 300 are mixed more fully, and the oxygen content of the formed mixed gas is more sufficient, which is conducive to the full combustion of the mixed gas. Compared with the traditional structure in which the primary air port 310 is arranged on the second side 120 of the panel 100, the primary air port 310 in the present application can eject a larger amount of air, so that the oxygen content of the mixed gas is higher, and finally the flame force of the flame formed after the mixed gas in the combustion part 200 is ignited can be stronger and more stable.

[0044] After the blowing section 400 is disposed on the panel 100, the blowing section 400 can accelerate the air located on the first side 110 of the panel 100 to enter the injection section 300 through the primary air port 310, thereby making the amount of air entering the injection section 300 through the primary air port 310 more sufficient, thereby making the oxygen content of the mixed gas input from the injection section 300 to the combustion section 200 higher.

[0045] Specifically, the air outlet 410 of the ejection part 300 may be arranged to face the primary air port 310 , and the blowing part 400 may introduce air outside the combustion device into the ejection part 300 through the primary air port 310 .

[0046] In the combustion device proposed in the embodiment of the present application, the primary air port 310 provided in the ejection part 300 allows air outside the combustion device to enter the ejection part 300 through the primary air port 310, and the air is mixed with the fuel gas entering the ejection part 300 to form a mixed gas. The ejection part 300 is connected with the combustion part 200, so that the mixed gas in the ejection part 300 can be input into the combustion part 200 and ignited to form a flame. The primary air port 310 of the ejection part 300 and the combustion part 200 are both arranged on the first side 110 of the panel 100, so that the combustion device has an upper air inlet structure, and the air located on the first side 110 of the panel 100 can fully enter the ejection part 300, so that the mixed gas in the ejection part 300 has sufficient oxygen content and burns more fully. The blowing section 400 can accelerate the air on the first side 110 of the panel 100 and introduce it into the ejection section 300, which can further increase the oxygen content of the mixed gas in the ejection section 300, so that the mixed gas input from the ejection section 300 to the combustion section 200 can burn more completely.

[0047] In some embodiments, since the injection section 300 and the combustion section 200 are connected, an air outlet 320 is provided on the injection section 300, and an air inlet 210 is provided on the combustion section 200. The air outlet 320 of the injection section 300 and the air inlet 210 of the combustion section 200 are arranged correspondingly so that the mixed gas in the injection section 300 can be input into the combustion section 200. The air outlet 320 of the injection section 300 and the air inlet 210 of the combustion section 200 can be arranged at intervals, and the air outlet 320 of the injection section 300 and the air inlet 210 of the combustion section 200 are arranged relative to each other, so that the gap between the air outlet 320 of the injection section 300 and the air inlet 210 of the combustion section 200 can constitute a primary air port 310, and the air located around the above-mentioned gap can be injected into the injection section 300, so that the opening of the primary air port 310 is arranged around the connection between the injection section 300 and the combustion section 200, the opening of the primary air port 310 is larger, and the amount of air injected into the injection section 300 through the primary air port 310 is larger. Correspondingly, the oxygen content of the mixed gas input from the injection section 300 to the combustion section 200 is higher, and it can be burned more fully.

[0048] The air outlet 320 of the injection section 300 and the air inlet 210 of the combustion section 200 are arranged relative to each other, so that the air outlet 320 of the injection section 300 is directed toward the air inlet 210 of the combustion section 200. In this way, the flow direction of the fuel gas output from the air outlet 320 of the injection section 300 can be directed toward the combustion section 200, so that the fuel gas can be directly input into the combustion section 200, thereby preventing the fuel gas from leaking between the injection section 300 and the combustion section 200.

[0049] It should also be noted that in order to further prevent the fuel gas from leaking in the gap between the air outlet 320 of the injection section 300 and the air inlet 210 of the combustion section 200, the diameter of the opening of the air inlet 210 of the combustion section 200 can be set to be larger than the diameter of the opening of the air outlet 320 of the injection section 300. In this way, even if the fuel gas output from the air outlet 320 of the injection section 300 undergoes a certain degree of natural diffusion, the diffused fuel gas can still be encompassed by the air inlet 210 of the combustion section 200, thereby preventing the fuel gas from leaking.

[0050] Specifically, an outward-expanding umbrella-shaped structure may be provided at the air inlet 210 of the combustion section 200 , so that the air inlet 210 of the combustion section 200 may also guide the fuel gas into the combustion section 200 .

[0051] In addition, in other embodiments, the ejection part 300 may be provided with a plurality of primary air ports 310 , and the plurality of primary air ports 310 may be distributed in various parts of the ejection part 300 , so that external air may enter the ejection part 300 more fully.

[0052] In some embodiments, in order to make the structure of the combustion device of the present application more compact, the blasting part 400 can be arranged in the ejection part 300. Specifically, the ejection part 300 can be provided with an air inlet 340, and the air inlet 340 is connected to the gas channel in the ejection part 300. The blasting part 400 can input the air outside the combustion device into the ejection part 300 through the air inlet 340. The ejection part 300 is provided with an air outlet 410. The air outlet 410 of the ejection part 300 and the air inlet of the ejection part 300 are connected. The air outlet 410 of the ejection section 300 is arranged to face the air inlet 210 of the combustion section 200, so that the blast section 400 introduces the air outside the combustion device into the ejection section 300 through the air inlet 340 of the ejection section 300 and then outputs the air into the combustion section 200 through the air outlet 410 of the ejection section 300, so that the air input into the combustion section 200 through the blast section 400 can be mixed again with the mixed gas input into the combustion section 200 through the ejection section 300.

[0053] In addition, when the blowing section 400 inputs external air into the combustion section 200 through the air outlet 410 of the injection section 300, the airflow formed by the blowing section 400 can also drive the air around the primary air port 310 of the injection section 300 to enter the combustion section 200 more quickly, so as to improve the efficiency of the air on the first side 110 of the panel 100 entering the injection section 300.

[0054] It should be understood that the air inlet 340 of the injection section 300 and the air outlet 410 of the injection section 300 can be set to be separately connected, so that there is a pipeline in the injection section 300 that connects the air inlet 340 of the injection section 300 and the air outlet 410 of the injection section 300. The blowing section 400 can introduce external air into the injection section 300, and then directly input it into the combustion section 200 through the air outlet 410 of the injection section 300, so that the air introduced by the blowing section 400 is mixed again with the mixed gas entering the combustion section 200 to increase the oxygen content of the mixed gas in the combustion section 200.

[0055] Of course, the air inlet 340 of the ejection part 300 can also be arranged to communicate with the gas channel in the ejection part 300, so that the blast part 400 can eject the air outside the combustion device into the ejection part 300 through the air inlet 340 of the ejection part 300, and part of the air ejected by the blast part 400 can be directly mixed with the fuel gas in the combustion channel of the ejection part 300, so that the fuel gas can be mixed with the air in the gas channel in the ejection part 300 to form a mixed gas, and then the mixed gas in the ejection part 300 can be mixed again with the air ejected by the primary air port 310 of the ejection part 300 in the process of entering the combustion part 200, so as to further increase the oxygen content of the mixed gas. The air outlet 410 provided on the ejection part 300 can increase the gas outlet flow rate of the ejection part 300, so that the air ejected into the ejection part 300 by the blast part 400 can be fully output from the ejection part 300 to the combustion part 200.

[0056] In some embodiments, the ejection unit 300 of the present application may be provided with a plurality of air outlets 410, and the plurality of air outlets 410 are all opposite to the air inlet 210 of the combustion unit 200, so that the air introduced into the ejection unit 300 by the blast unit 400 can be discharged through the plurality of air outlets 410, so that the air introduced into the ejection unit 300 by the blast unit 400 can be fully input into the combustion unit 200. The plurality of air outlets 410 of the ejection unit 300 may be arranged around the air outlet 320 of the ejection unit 300, so that the plurality of air streams outputted by the air outlets 410 of the ejection unit 300 can be arranged around the fuel gas stream outputted from the air outlet 320 of the ejection unit 300 in the middle, so that the plurality of air streams can be mixed more fully with the fuel gas stream, thereby making the oxygen content of the mixed gas input into the combustion unit 200 sufficient.

[0057] Of course, in other embodiments, the ejection unit 300 of the present application may also be provided with a plurality of gas outlets 320, each gas outlet 320 being opposite to the gas inlet 210 of the combustion unit 200, so that the fuel gas in the ejection unit 300 can be input into the combustion unit 200 through the plurality of gas outlets 320, so that the fuel gas in the combustion unit 200 is sufficiently inlet. The gas outlets 320 of the plurality of ejection units 300 may be arranged around the air outlet 410 of the ejection unit 300, so that the plurality of gas streams outputted by the gas outlets 320 of the plurality of ejection units 300 may be arranged around the air stream outputted by the air outlet 410 of the ejection unit 300 in the middle, so that the plurality of gas streams and the air stream are mixed more fully, and thus the oxygen content of the mixed gas inputted into the combustion unit 200 is sufficient.

[0058] In some embodiments, the air inlet 340 of the injection portion 300 of the present application can be set on the second side 120 of the panel 100, so that the blowing portion 400 can introduce the air located on the second side 120 of the panel 100 into the injection portion 300 through the air inlet 340 of the injection portion 300, thereby making full use of the air on both sides of the panel 100 and avoiding the blowing portion 400 and the primary air port 310 of the injection portion 300 set on the first side 110 of the panel 100 from competing for air.

[0059] Specifically, the induction portion 300 can be configured to penetrate the panel 100, with a portion of the induction portion 300 located on the first side 110 of the panel 100, and another portion of the induction portion 300 located on the second side 120 of the panel 100. The distribution of the induction portion 300 on the first side 110 and the second side 120 of the panel 100 can make the combustion device structure of the present application more compact. The air inlet 340 of the injection portion 300 can be arranged on the portion of the injection portion 300 located on the second side 120 of the panel 100. Accordingly, the air located on the second side 120 of the panel 100 can be introduced into the injection portion 300 by the blowing portion 400. The blowing portion 400 can be specifically arranged in the injection portion 300 and adjacent to the air inlet 340 of the blowing portion 400. Of course, the blowing portion 400 can also be arranged outside the injection portion 300 and opposite to the air inlet 340 of the injection portion 300. In this way, the blowing portion 400 can introduce the air on the second side 120 of the panel 100 into the injection portion 300.

[0060] Since the ejection part 300 passes through the panel 100, an opening is provided on the panel 100 for the ejection part 300 to pass through. The shape of the opening on the panel 100 can be set to match the outer shape of the ejection part 300. This arrangement allows the panel 100 to fix the ejection part 300, so that the ejection part 300 can remain stable after being installed on the panel 100.

[0061] At the same time, a gas port 330 connected to the gas pipeline can be provided on the first gas supply part, and the gas port 330 can also be arranged on the part of the ejection part 300 located on the second side 120 of the panel 100, so that the gas pipe can extend to the second side 120 of the panel 100 and communicate with the ejection part 300, so that the first side 110 of the panel 100 has a larger space for installing other components of the combustion device. In addition, the gas pipeline extends to the second side 120 of the panel 100 and communicates with the ejection part 300, and the panel 100 can also separate the combustion part 200 from the gas pipe. After the mixed gas in the gas part is ignited, a large amount of heat will be generated. The panel 100 can isolate part of the heat generated by the combustion part 200, so that the temperature of the gas pipeline located on the side of the panel 100 will not be too high, thereby making the safety of the combustion device of the present application more reliable.

[0062] When the combustion port and the air inlet 340 of the injection section 300 of the present application are both arranged on the portion of the injection section 300 located on the second side 120 of the panel 100, the gas port 330 and the air inlet 340 of the injection section 300 can be arranged on opposite sides of the injection section 300, so that the gas port 330 and the air inlet 340 of the injection section 300 will not be concentrated on a certain side wall of the injection section 300, so that the opening size of the gas port 330 and the air inlet 340 of the injection section 300 can be set relatively larger, so that the fuel gas flow rate input into the injection section 300 and the air flow rate introduced into the injection section 300 through the blowing section 400 are both relatively larger, and finally the flow rate of the mixed gas input into the combustion section 200 can be sufficient.

[0063] The combustion portion 200 of the present application can be configured to include an inner combustion air duct 220 and an outer combustion air duct 230. After the mixed gas enters the combustion portion 200, it can enter the inner combustion air duct 220 and the outer combustion air duct 230 respectively. The outer combustion air duct 230 is arranged around the inner combustion air duct 220, so that the flame formed after the mixed gas in the outer combustion air duct 230 is ignited can surround the flame formed after the mixed gas in the inner combustion air duct 220 is ignited, so that the flame formed by the combustion device has an inner flame and an outer flame. The inner flame and the outer flame can evenly heat the bottom center and the surrounding area of ​​the cookware, and the cookware can be heated evenly.

[0064] The inner combustion air passage 220 and the outer combustion air passage 230 can both be communicated with the air inlet 210 of the combustion part 200, so that the mixed gas output by the ejection part 300 can enter the inner combustion air passage 220 and the outer combustion air passage 230 of the combustion part 200 through the air inlet 210 of the combustion part 200. Of course, the combustion part 200 can also be provided with two air inlets 210, and the two air inlets 210 can correspond to the inner combustion air passage 220 and the outer combustion air passage 230 of the combustion part 200 respectively, and the mixed gas output by the ejection part 300 can be respectively input into the inner combustion air passage 220 and the outer combustion air passage 230 through the two air inlets 210 of the combustion part 200, so that the mixed gas in the inner combustion air passage 220 and the outer combustion air passage 230 is sufficient.

[0065] In some embodiments, the number of the ejection parts 300 of the present application can be set to two, and the two ejection parts 300 can be respectively arranged corresponding to the two air inlets 210 of the combustion part 200, so that the two ejection parts 300 can respectively input the mixed gas into the inner combustion gas passage 220 and the outer combustion gas passage 230. Specifically, the two ejection parts 300 are both arranged on the panel 100, and the parts of the two ejection parts 300 located on the first side 110 of the panel 100 both have an air outlet 320, and the two ejection parts 300 are also both provided with a primary air port 310, and the two primary air ports 310 can respectively introduce external air into the two ejection parts 300.

[0066] Specifically, the air outlets 320 of the two injection parts 300 can be arranged opposite to the two air inlets 210 of the combustion part 200, so that the gaps between the air outlets 320 of the two injection parts 300 and the two air inlets 210 of the combustion part 200 constitute two primary air ports 310, so that the oxygen content of the mixed gas input into the inner combustion air duct 220 and the outer combustion air duct 230 is sufficient.

[0067] Of course, the number of the blowing parts 400 can also be set to two, and the two blowing parts 400 can respectively accelerate the external air to enter the two injection parts 300 through the two primary air ports 310 to ensure that the air volume in the two injection parts 300 is sufficient.

[0068] The combustion device provided in the embodiment of the present application may also be provided with a partition 240, which may be provided between the primary air ports 310 of the two injection parts 300, and the partition 240 may separate the two primary air ports 310. Since the air introduced by the two primary air ports 310 may enter the inner combustion air passage 220 and the outer combustion air passage 230 respectively, after the partition 240 is provided, the two primary air ports 310 may respectively introduce the air on the opposite sides of the partition 240 into the injection part 300, thereby preventing the two primary air ports 310 from competing for air with each other, so as to ensure that the amount of air entering the two injection parts 300 through the two primary air ports 310 is sufficient, thereby preventing the inner combustion air passage 220 and the outer combustion air passage 230 from competing for air with each other, so that the amount of air entering the outer combustion air passage 230 and the amount of air entering the inner combustion air passage 220 are balanced and sufficient, and the flames formed by the inner combustion air passage 220 and the outer combustion air passage 230 are also more stable.

[0069] Specifically, the partition 240 can be fixed on the side of the combustion section 200 facing the panel 100, and the partition 240 is located between the two air inlets 210 of the combustion section 200, one end of the partition 240 is connected to the combustion section 200, and the other end of the partition 240 extends toward the injection section 300 to between the two air outlets 320 of the injection section 300, so that the two primary air ports 310 can be separated.

[0070] In the combustion device provided in the embodiment of the present application, a gap may be provided between the inner combustion air passage 220 and the outer combustion air passage 230, and the gap forms a secondary air port 250. Specifically, an inner ring air outlet 221 communicating with the inner combustion air passage 220 and an outer ring air outlet 231 communicating with the outer combustion air passage 230 may be provided on the combustion portion 200, and the mixed gas in the inner combustion air passage 220 may be discharged through the inner ring air outlet 221, and the mixed gas in the outer combustion air passage 230 may be discharged through the outer ring air outlet 231. The inner ring air outlet 221 may be provided on the outer wall of the inner combustion air passage 220 facing the outer combustion air passage 230, so that the external air can also enter the secondary air port 250 between the inner combustion air passage 220 and the outer combustion air passage 230, and mix with the mixed gas discharged from the inner combustion air passage 220, thereby further improving the oxygen content of the mixed gas discharged from the inner combustion air passage 220, so that the mixed gas can be fully burned.

[0071] The outer ring air outlet 231 can be set on the outer wall of the outer combustion air duct 230 facing away from the inner combustion air duct 220. Specifically, the outer ring air outlet 231 is located on the outer wall of the outer combustion air duct 230. The air located outside the combustion part 200 can be further mixed with the mixed gas discharged from the outer combustion air duct 230 to increase the oxygen content of the mixed gas.
