Description

Technical Field

[0002] In the related art, most gas stoves adopt an upward air intake burner, and this kind of burner generally uses an external flame combustion method. In this combustion method, the flame holes of the inner ring and the outer ring of the burner are all facing outward, that is to say, the flame burns towards the outside of the gas stove. However, when the cook needs to use the high-power mode of the gas stove, if the entrainment effect of the primary air of the burner is not good, it is difficult to supplement the secondary air of the inner ring fire cover, resulting in too fast a flow rate of the gas of the burner, and frequent occurrence of the flame leaving the combustion zone. This leads to a serious phenomenon of flame drifting outward, that is, the flame will deviate from the gas stove and drift towards the cook. Therefore, during use, the cook is easily scalded by this phenomenon, which seriously affects the cook's experience. Summary of the Invention

[0058] In the related art, most gas stoves adopt an upward air inlet burner, and such a burner generally uses an external flame combustion method. In this combustion method, the flame holes of the inner and outer rings of the burner are all facing outward, that is to say, the flame burns towards the outside of the gas stove. However, when the cook needs to use the high-power mode of the gas stove, if the entrainment effect of the primary air of the burner is not good, it is difficult to supplement the secondary air of the inner ring fire cap, resulting in too fast a flow rate of the gas in the burner, and frequent occurrence of the flame leaving the combustion zone. This leads to a serious phenomenon of the flame floating outward, that is, the flame will deviate from the gas stove and float towards the cook. Therefore, during use, the cook is easily scalded by this phenomenon, which seriously affects the cook's experience.

[0059] The following is based on Figures 1 to 10 to introduce the gas distribution plate 100 provided by the embodiments of the present application.

[0060] As Figures 3 to 5 shown, a gas distribution plate 100 provided by an embodiment of the present application includes a plate main body 110, a first injection pipe 120, a second injection pipe 130, a first intake partition 140, and a second intake partition 150. It should be noted that the gas distribution plate 100 provided by the present application is placed in the burner 10 to split the gas input from the gas pipeline so that the gas can be evenly sprayed onto each flame hole of the burner 10.

[0061] Specifically, a first air supplement channel 111 penetrating in the thickness direction is provided on the disk body 110, and a first air outlet 112 and a second air outlet 113 are provided on one side of the disk body 110. Both the first ejector tube 120 and the second ejector tube 130 are located on the other side of the disk body 110. The second ejector tube 130 is disposed opposite to the first ejector tube 120. The first air outlet 112 is connected and communicated with the first ejector tube 120, and the second air outlet 113 is connected and communicated with the second ejector tube 130.

[0062] Wherein, one of the first air outlet 112 and the second air outlet 113 is an inner ring air outlet, and the other is an outer ring air outlet. The inner ring air outlet can supply gas to the inner ring fire tray of the burner 10, and the outer ring air outlet can supply gas to the outer ring fire tray of the burner 10. Correspondingly, when the first air outlet 112 is the inner ring air outlet, the first ejector tube 120 is the inner ring ejector tube; when the first air outlet 112 is the outer ring air outlet, the first ejector tube 120 is the outer ring ejector tube. When the second air outlet 113 is the inner ring air outlet, the second ejector tube 130 is the inner ring ejector tube; when the second air outlet 113 is the outer ring air outlet, the second ejector tube 130 is the outer ring ejector tube.

[0063] In the embodiment provided by the application, the first air outlet 112 is the outer ring air outlet, and the second air outlet 113 is the inner ring air outlet.

[0064] As Figure 3 shown, the first air inlet partition 140 is connected to the side of the first ejector tube 120 facing the second ejector tube 130, the second air inlet partition 150 is connected to the side of the second ejector tube 130 facing the first ejector tube 120. The second air inlet partition 150 is opposite to the first air inlet partition 140 and defines a second air supplement channel 160, and the second air supplement channel 160 is communicated with the first air supplement channel 111. In this way, since the two air inlet partitions separate the first ejector tube 120 and the second ejector tube 130, when the burner 10 performs secondary air supplement, the supplemented air is not easily sucked by the airflow generated by the ejector tube. Furthermore, sufficient air can be supplemented to the burner 10. Ensure that the burner 10 obtains necessary air during the combustion process, making the combustion process more complete and efficient, avoiding the pollution caused by incomplete combustion, and at the same time improving the energy utilization rate. And, since the air supplement is sufficient, the flame can remain stable in the combustion zone, reducing the possibility of the flame floating outwards and improving the user experience.

[0065] Wherein, as Figure 3 and Figure 5As shown, on the side of the first intake partition 140 facing away from the second intake partition 150, there is a guiding inclined surface 141, and the guiding inclined surface 141 can guide the entrained air flow into the first entrainment pipe 120. Of course, the setting manner of the guiding inclined surface 141 is not limited to this. In some examples of the present application, on the side of the second intake partition 150 facing away from the first intake partition 140, there is a guiding inclined surface 141, and the guiding inclined surface 141 can guide the entrained air flow into the second entrainment pipe 130. Or, in some other examples of the present application, on the side of the first intake partition 140 facing away from the second intake partition 150, there is a guiding inclined surface 141, and on the side of the second intake partition 150 facing away from the first intake partition 140, there is also a guiding inclined surface 141. In this way, it can make the entrained air flow have a certain directionality before entering the entrainment pipe, so as to better ensure the direction of the entrained air flow, minimize the energy loss of the air flow during the transmission process to the greatest extent, thereby improving the entrainment effect, and improving the stability and combustion effect of the burner 10.

[0066] According to the air distribution plate 100 provided by the present application, by arranging the first intake partition 140 on the side of the first entrainment pipe 120 facing the second entrainment pipe 130, and arranging the second intake partition 150 on the side of the second entrainment pipe 130 facing the first entrainment pipe 120, the second intake partition 150 is opposite to the first intake partition 140 and defines a second air supplement channel 160, and the second air supplement channel 160 communicates with the first air supplement channel 111. And on the side of the first intake partition 140 facing away from the second intake partition 150, there is a guiding inclined surface 141, and on the side of the second intake partition 150 facing away from the first intake partition 140, there is also a guiding inclined surface 141. Among them, the first air supplement channel 111 and the second air supplement channel 160 are secondary air intake areas, and the first entrainment pipe 120 and the second entrainment pipe 130 are primary air intake areas. In this way, not only can the primary air intake area and the secondary air intake area of the air distribution plate 100 be separated to avoid the primary and secondary air competing for air, supplement sufficient air for the burner 10, ensure that the burner 10 obtains the necessary air during the combustion process, and make the combustion process more complete and efficient, but also the entrainment effect of the burner 10 during the primary air entrainment can be improved, and the energy loss of the air flow during the transmission process can be reduced, thereby improving the stability and combustion effect of the burner 10.

[0067] As Figure 3As shown, in some embodiments of the present application, the guiding inclined surface 141 includes a first wall surface 142 and a second wall surface 143 connected to each other, and the second wall surface 143 and the first wall surface 142 are arranged at an obtuse angle. In this way, when the air flow entering the burner 10 passes through the guiding inclined surface 141, it can not only be smoothly guided to the air supplement channel, but also be dispersed to a certain extent to form a more extensive and uniform air flow distribution. The obtuse angle arrangement between the first wall surface 142 and the second wall surface 143 enables the entering air flow to spread over a wider range after passing through the guiding inclined surface 141, which can not only sufficiently supply the combustion area, but also prevent some air flows from being too concentrated and affecting the combustion effect. Therefore, this obtuse angle setting not only improves the combustion efficiency, but also helps to optimize the overall combustion effect.

[0068] As Figure 3 shown, in some embodiments of the present application, the first wall surface 142 is parallel to the side wall surface of the first air inlet partition 140 facing the second air supplement channel 160. In this way, when the air flow passes through the guiding inclined surface 141, it will be smoothly guided to the air supplement channel, which is beneficial to ensuring that the air flow can smoothly enter the combustion area. This design is crucial for the working efficiency of the burner 10 because it can ensure that the burner 10 can effectively obtain sufficient oxygen-rich air flow during operation. Such an air flow will make the combustion process of the gas more complete and efficient, further improving the energy use efficiency of the entire combustion system.

[0069] As Figure 5 shown, in some embodiments of the present application, a third ejector tube 170 is provided on one side of the air distribution plate 100, and the third ejector tube 170 and the first ejector tube 120 are arranged at intervals to form a segmented ejector tube. The segmented ejector tube design has extremely high flexibility and can select appropriate segment numbers and layouts according to specific operating requirements and environmental conditions to meet the optimization requirements of the burner 10 in various working environments. The design of the segmented ejector tube can also enable the air flows in different segments to be more effectively blended and mixed after entering the ejector tube, thereby greatly improving the combustion efficiency, reducing energy waste, and enhancing the environmental protection effect. At the same time, this design is also beneficial to improving the adaptability and adjustability of the burner 10, and can better meet the specific requirements of different users or working environments.

[0070] Of course, the setting method of the segmented ejector tube is not limited to this. In some other embodiments of the present application, the third ejector tube 170 can also be arranged at intervals with the second ejector tube 130 to construct a segmented ejector tube. Or in some other embodiments of the present application, a fourth ejector tube can also be arranged on the gas distribution plate 100, so that the fourth ejector tube is arranged at intervals with the second ejector tube 130 to construct a segmented ejector tube, and the third ejector tube 170 is arranged at intervals with the first ejector tube 120 to construct a segmented ejector tube, further improving the ejector efficiency of the burner 10.

[0071] As Figure 1 and Figure 2 shown, the present application also provides a burner 10, including a gas distribution plate 100, an inner ring burner cap 200 and an outer ring burner cap 300. Wherein the gas distribution plate 100 is the above-mentioned gas distribution plate 100, the inner ring burner cap 200 covers the second gas outlet 113, the inner ring burner cap 200 is provided with inner ring fire holes 201, the second gas outlet 113 provides gas for the inner ring burner cap 200, and the first air supplement channel 111 and the second air supplement channel 160 can supplement air for the inner ring burner cap 200, improving the combustion efficiency of the burner 10. The outer ring burner cap 300 covers the first gas outlet 112, the first gas outlet 112 can provide gas for the outer ring burner cap 300, and the outer circumference of the outer ring burner cap 300 is provided with outer ring fire holes 301.

[0072] As Figure 7 and Figure 8 shown, in some embodiments of the present application, a thickening boss 202 is provided on the side of the inner ring burner cap 200 facing the gas distribution plate 100. Wherein, the thickness of the thickening boss 202 is H1, and the thickness of the remaining positions on the side of the inner ring burner cap 200 facing the gas distribution plate 100 is H2, and H1 > H2. And the depth of the inner ring fire holes 201 located on the thickening boss 202 is greater than the depth of the inner ring fire holes 201 at the remaining positions. In this way, it is beneficial to adjust the flow rate of the air flow, so that the gas flow rate at the inner ring fire holes 201 on the thickening boss 202 is slowed down, thereby further avoiding the flame detachment phenomenon caused by too fast flow rate at the inner ring fire holes 201. The flame detachment phenomenon will lead to poor combustion effect and safety hazards. Therefore, by reducing the gas flow rate at the inner ring fire holes 201, the combustion of the burner 10 can be made more effective, and the safety during use is also increased. In addition, this setting also facilitates more precise regulation of the air flow, optimizes the combustion effect, gives full play to the maximum efficiency of the burner 10, and increases the combustion efficiency and safety of the burner 10.

[0073] As Figure 9 and Figure 10As shown, in some embodiments of the present application, the outer ring burner cap 300 includes a first outer ring 302, a second outer ring 303, and a connecting portion 304. The connecting portion 304 is connected between the first outer ring 302 and the second outer ring 303. The first outer ring 302 is sleeved on the inner ring burner cap 200, and the second outer ring 303 is sleeved on the first outer ring 302. In the radially outward direction of the second outer ring 303, the first outer ring 302 is spaced apart from the second outer ring 303. In the circumferential direction of the second outer ring 303, the thickness H3 of a partial structure of the second outer ring 303 is greater than the thickness H4 of the remaining partial structure, and the flame hole depth on the partial structure of the second outer ring 303 is greater than the flame hole depth of the remaining partial structure of the second outer ring 303. In this way, it is beneficial to adjust the flow rate of the gas flow, so that the gas flow rate at the outer ring flame holes 301 on the second outer ring 303 is slowed down, thereby avoiding the flame lift phenomenon caused by too fast flow rate at the inner ring flame holes 201, and further increasing the combustion efficiency and safety of the burner 10.

[0074] As shown in Figures 6 to 8 As shown, in some embodiments of the present application, a slope 203 is provided on the side of the inner ring burner cap 200 facing away from the gas distribution plate 100. In the radially outward direction of the inner ring burner cap 200, the slope 203 gradually moves away from the gas distribution plate 100, and the inner ring flame holes 201 are provided on the slope 203. In this way, the design of the slope 203 helps to disperse the gas flow, so that it is distributed at a wider angle when the gas enters the flame holes, thereby improving the combustion efficiency. And the design of the slope 203 enables the heat to be better dispersed, provides better protection for the flame holes, reduces the thermal stress of the flame holes, and thus can extend the service life of the equipment.

[0075] During cooking, since the cookware will be directly placed on the burner cap, therefore, the design of the slope 203 of the inner ring burner cap 200 also enables the heat to be more evenly distributed on the item to be heated, improving the cooking effect.

[0076] As shown in Figure 6 As shown, in some embodiments of the present application, a circumferential wall surface 204 is provided below the slope 203, and an ignition hole 205 and a thermocouple flame protection hole 206 are provided on the circumferential wall surface 204. The main function of the ignition hole 205 is to draw fire from the ignition source to ignite the gas. The main function of the thermocouple flame protection hole 206 is to rely on the thermocouple. When the fire source goes out or is abnormal, the thermocouple will sense the temperature change, and then disconnect the gas valve to stop the gas supply, achieving the purpose of safety protection.

[0077] As shown in Figure 6As shown, in some embodiments of the present application, a flange 207 is provided at the intersection of the circumferential wall surface 204 and the inclined surface 203. The flange 207 extends towards the radially inner side of the inner ring burner cap 200, and the flange 207 shields the circumferential wall surface 204. The flange 207 can provide an additional protection function during cooking. Specifically, if the food or soup in the pot boils over during cooking and flows above the burner 10, the flange 207 can effectively block the overflowing soup from flowing to the thermocouple fire protection hole 206. Without the blockage of the flange 207, the overflowing soup may flow into the thermocouple fire protection hole 206, causing the flame of the burner 10 to go out. With the presence of the flange 207, the occurrence of this situation can be significantly reduced, ensuring the smooth progress of the cooking process and avoiding potential safety hazards caused by the extinguishing of the burner 10.

[0078] As Figures 1 to 3 shown, in some embodiments of the present application, the burner 10 further includes a bottom cup 400 and a support frame 500. The bottom cup 400 is connected to the gas distribution plate 100. The support frame 500 is provided on the bottom cup 400. A positioning boss 501 is provided on the support frame 500, and a positioning hole 101 is provided on the gas distribution plate 100. The positioning boss 501 cooperates with the positioning hole 101 to fix the gas distribution plate 100 to the bottom cup 400. In this way, with the cooperation of the positioning boss 501 and the positioning hole 101, the gas distribution plate 100 can be easily fixed to the bottom cup 400, ensuring that the gas distribution plate 100 does not move during use, thereby effectively maintaining the stability of the burner 10 and avoiding accidental detachment of the gas distribution plate 100 during use, thus ensuring the safe use of the burner 10. It also simplifies the assembly process of the burner 10 without the need for a complex assembly process.

[0079] As Figure 1 and Figure 2 shown, in some embodiments of the present application, fixing columns 401 are further provided on the bottom cup 400. The fixing columns 401 can cooperate with one of the first air inlet partition 140 and the second air inlet partition 150 to fix the gas distribution plate 100 to the bottom cup 400. In this embodiment, there are two fixing columns 401. When fixing the gas distribution plate 100 to the bottom cup 400, the first air inlet partition 140 can be aligned with one of the fixing columns 401, and the second air inlet partition 150 can be aligned with the other fixing column 401, and the air inlet partition is engaged with the fixing column 401 through the guiding inclined surface 141. When the user needs to clean the gas distribution plate 100, the gas distribution plate 100 can also be conveniently taken out for cleaning. The design of the guiding inclined surface 141 facilitates the user to place the gas distribution plate 100 in place more easily after taking it out for cleaning.

[0080] The gas distribution plate 100 provided by the embodiment of the present application can effectively split the gas, enabling the gas to be evenly sprayed onto each flame hole of the burner 10, thereby improving the combustion efficiency. By providing the first injection pipe 120, the second injection pipe 130, the inner ring gas outlet, and the outer ring gas outlet, the distribution of the gas on the inner ring burner cap 200 and the outer ring burner cap 300 of the burner 10 can be conveniently carried out to meet the gas requirements of different burner caps. By providing the intake partition plate and the air supplement channel, when the burner 10 performs secondary air supplementation, the supplemented air is not easily sucked in by the airflow generated by the injection pipe, ensuring that the burner 10 obtains the necessary air during the combustion process. In addition, for the gas distribution plate 100 of the present application, by means of the guiding inclined surface 141, the injection airflow can have a certain directionality before entering the injection pipe, effectively reducing the energy loss during the transmission of the airflow, and improving the stability and combustion effect of the burner 10. By providing a segmented injection pipe, the number of segments and the layout can be adjusted according to specific working requirements and conditions to achieve the optimization of the performance of the burner 10.

[0081] According to the gas distribution plate 100 provided by the present application, not only can the combustion efficiency of the burner 10 be improved, but also the stability and combustion effect of the burner 10 under different working conditions can be improved, enhancing the energy utilization rate and the user experience.

[0082] The burner 10 provided by the present application includes the above-mentioned gas distribution plate 100, so it also has the beneficial effects of the above-mentioned gas distribution plate 100.

[0083] In addition, for the burner 10 provided by the present application, by providing thickened parts on both the inner ring burner cap 200 and the outer ring burner cap 300, the depth of the inner ring flame holes 201 on the thickened boss 202 of the inner ring burner cap 200 is greater than the depth of the remaining inner ring flame holes 201, and the depth of the outer ring flame holes 301 on the thickened part of the outer ring burner cap 300 is greater than the depth of the remaining outer ring flame holes 301. In this way, the flow rate of the airflow can be effectively adjusted to prevent the flame lift phenomenon caused by too fast gas flow rate, thereby improving the combustion efficiency and safety. Also, through the design of the inclined surface 203 on the inner ring burner cap 200, the heat can be better dispersed, providing better protection for the inner ring flame holes 201, reducing the thermal stress of the inner ring flame holes 201, and thus the service life of the overall device of the burner 10 can be extended. At the same time, the design of the inclined surface 203 also enables the heat to be more evenly distributed on the food to be heated, improving the cooking effect.

[0084] By providing a flange 207 on the inner ring pot lid 200, an additional protection function can be provided during cooking, such as blocking the overflowing soup from flowing to the thermocouple fire protection hole 206, ensuring the smooth progress of the cooking process, and at the same time avoiding potential safety hazards caused by the flame extinction of the burner 10.

[0085] Through the cooperation of the positioning boss 501 and the positioning hole 101, the air distribution plate 100 can be easily fixed on the bottom cup 400, simplifying the assembly process and eliminating the need for complex assembly. By providing the fixing post 401, it is convenient to remove the air distribution plate 100 for cleaning when cleaning the air distribution plate 100, while ensuring the accuracy and stability during reassembly.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than limiting the present application. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered within the scope of the claims of the present application.
