[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0043] In the related art, the gas stove includes a valve body. After the valve body is opened, the gas of bottled liquefied gas or pipeline natural gas is transmitted along the pipeline, and the gas passes through the valve body and is sprayed out through the nozzle. The gas sprayed from the nozzle is sprayed into the interior of the burner. In the process of gas spraying into the interior of the burner, air is simultaneously introduced. For the introduction of air, please refer to the related art. It is generally based on the Venturi principle. In the process of gas spraying into the interior of the burner, a negative pressure is formed on the surrounding environment, so that the air of the surrounding environment is synchronously introduced into the interior of the burner with the injection of gas (this part of the air entering the interior of the burner through the introduction effect is called introduction air, and the introduction air is primary air). The introduction air is mixed with the gas in the interior of the burner and then sprayed out from the interior of the burner, and then ignited to form a flame. In the process of gas combustion, through buoyancy and suction, the surrounding environment will supplement air to the flame (this air is called secondary air), thereby assisting the combustion of the gas. It can be seen that the amount of primary air and the amount of secondary air are the core factors to ensure the complete combustion of the ejected gas, but the amount of primary air is affected by the structure and working conditions, and the supplement of secondary air relies on buoyancy and suction, which is a passive supplement and has high requirements on the size of components. Therefore, the gas is mostly in a state of low oxygen combustion when it is burned only by induced air and suction of air from the surrounding environment, and the combustion is incomplete. To address this problem, the present application improves the burner to at least improve the combustion degree of the gas to a certain extent, thereby helping to improve the thermal efficiency of the gas stove.

[0044] The first aspect of the present application discloses a burner 100, Figure 1 and Figure 2 As shown, in some embodiments, the burner 100 includes a first surface 1001, which is a plane. The first surface 1001 is provided with a first burner 1210 and a second burner 1220. The first burner 1210 is used for spraying blast air and gas, and the second burner 1220 is used for spraying induced air and gas.

[0045] The first burner 1210 in the present technical solution is used for gas and blast air to be ejected, and the blast air provides sufficient oxygen to enable the gas ejected from the first burner 1210 to be fully burned, and the blast air can produce excess oxygen to assist the combustion of the gas ejected from the second burner 1220, so that the gas ejected from the second burner 1220 can also be fully burned under the action of the induced air and the excess oxygen provided by the blast air. Through such an arrangement, the gas ejected from the first burner 1210 and the second burner 1220 can eventually be fully burned with high combustion efficiency, which is beneficial to the improvement of the thermal efficiency of the gas stove, and the first burner 1210 and the second burner 1220 are arranged on the first surface 1001, and the first surface 1001 is a plane, which is convenient for cleaning the fire cover 1000 and avoiding blockage of the first burner 1210 and the second burner 1220.

[0046] The burner 100 is described below in conjunction with a gas stove. It can be understood that the burner 100 can be applied to other devices that work by burning gas in addition to the gas stove.

[0047] Specifically, the second burner 1220 is used for ejecting induced air and gas, that is, the induced air and gas enter the interior of the burner 100, and then eject from the interior of the burner 100 through the second burner 1220, and are ignited to form a flame. The gas supply can come from bottled liquefied gas or pipeline natural gas. The gas stove includes a valve body. After the valve body is opened, the gas is transmitted along the gas pipeline, the gas flows through the valve body and is ejected through the nozzle. The gas ejected from the nozzle is ejected into the interior of the burner 100. In the process of the gas being ejected into the interior of the burner 100, the air is ejected synchronously, so that the induced air follows the gas into the interior of the burner 100, and then the induced air and gas are ejected from the second burner 1220.

[0048] The first burner 1210 is used for supplying blast air and gas to be ejected, that is, blast air and gas enter the interior of the burner 100, and then eject from the interior of the burner 100 through the first burner 1210, and are ignited to form a flame. The gas supply can come from bottled liquefied gas or pipeline natural gas. The gas stove includes a valve body. After the valve body is opened, the gas is transmitted along the gas pipeline, flows through the valve body and is ejected through a nozzle. The gas ejected from the nozzle is injected into the interior of the burner 100. In this process, blast air is provided. The blast air is generated by a fluid machine, for example, by forced blowing of the fan 4000 to provide blast air. The blast air enters the interior of the burner 100 and mixes with the gas (the blast air is primary air), and then is ejected from the first burner 1210 with the gas. Compared with the induced air, the blast air can provide enough oxygen, so that the gas ejected from the first burner 1210 can be in an oxygen-rich combustion state, thereby fully burning the gas ejected from the first burner 1210 (the flame generated by the first burner 1210 can still draw in secondary air from the surrounding environment to participate in combustion).

[0049] The gas ejected from the second burner 1220 is not sufficient to be fully burned if it is only ejected air and sucked in the surrounding air. Since the first burner 1210 ejects blast air, it can provide enough oxygen, so that in addition to participating in the combustion of the gas ejected from the first burner 1210, the excess oxygen in the blast air can also be added to the gas ejected from the second burner 1220 to assist in the combustion of the gas ejected from the second burner 1220. Compared with the secondary air supplemented from the surrounding environment by the suction effect, the excess oxygen provided by the blast air ejected from the first burner 1210 is more actively added to the gas ejected from the second burner 1220, so that the gas ejected from the second burner 1220 is fully burned (the flame generated by the second burner 1220 can still suck in the secondary air from the surrounding environment to participate in the combustion). It can be seen that through the above scheme, the gas ejected from the first burner 1210 and the second burner 1220 can be fully burned, the combustion efficiency is high, and it is beneficial to improve the thermal efficiency of the gas stove. It is understandable that the full combustion mentioned herein is relative to the combustion state of only induced air and entrained air from the surrounding environment (i.e., relatively more full). In addition, in this embodiment, the first burner 1210 and the second burner 1220 are opened on the first surface 1001, and the first surface 1001 is a plane. The first surface 1001 set in a plane is easier to clean, avoiding clogging of the first burner 1210 and the second burner 1220.

[0050] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in some embodiments, the first surface 1001 is a horizontal surface. It is understandable that the gas stove is in a substantially horizontal installation state when in the installation environment, so that the cooker can be placed on the gas stove stably. When the first surface 1001 is a horizontal surface, the first burner 1210 and the second burner 1220 are at the same height, and the first burner 1210 and the second burner 1220 are at the same distance from the cooker, respectively, to ensure efficient heating of the cooker, which is conducive to improving the energy efficiency of the gas stove.

[0051] For example, the burner 100 includes a burner head 2000 and a fire cover 1000. The fire cover 1000 is arranged on the burner head 2000. The fire cover 1000 is provided with the aforementioned first surface 1001. Blast air and gas are introduced into the burner head 2000 and ejected from the fire cover 1000 through the first burner port 1210, and then ignited to form a flame. The induced air and gas are introduced into the burner head 2000 and ejected from the fire cover 1000 through the second burner port 1220, and then ignited to form a flame. When the cooker is placed above the burner 100, the first surface 1001 is opposite to the cooker, thereby directly heating the cooker. At this time, the top surface of the fire cover 1000 constitutes the first surface 1001, which is a horizontal plane.

[0052] Combination Figures 1 to 7 As shown, in some embodiments, the fire cover 1000 includes a first fire cover 1110 and a second fire cover 1120, the first fire cover 1110 surrounds the second fire cover 1120, one of the first fire port 1210 and the second fire port 1220 is arranged between the first fire cover 1110 and the second fire cover 1120, and the second fire cover 1120 is arranged with the other of the first fire port 1210 and the second fire port 1220.

[0053] For example, see Figure 5 As shown, a first fire port 1210 is arranged between the first fire cover 1110 and the second fire cover 1120, and a second fire port 1220 is arranged on the second fire cover 1120. At this time, the first fire port 1210 is formed between the top surface 1111 of the first fire cover and the top surface 1121 of the second fire cover, and the second fire port 1220 is formed on the top surface 1121 of the second fire cover. The top surface 1111 of the first fire cover and the top surface 1121 of the second fire cover constitute at least a part of the first surface 1001, so that the first fire port 1210 and the second fire port 1220 directly face the cooker.

[0054] As another example (not shown in the figure), a second flame port 1220 is provided between the first fire cover 1110 and the second fire cover 1120, and the second fire cover 1120 is provided with the first flame port 1210. At this time, the second flame port 1220 is formed between the top surface 1111 of the first fire cover and the top surface 1121 of the second fire cover, and the first flame port 1210 is formed on the top surface 1121 of the second fire cover. The top surface 1111 of the first fire cover and the top surface 1121 of the second fire cover constitute at least a part of the first surface 1001, so that the first flame port 1210 and the second flame port 1220 directly face the cooker.

[0055] Combination Figures 4 to 8 As shown, in some embodiments, the fire cover 1000 is provided with an air outlet channel 1300, and the air outlet channel 1300 is provided with a corner 1350, and the corner 1350 is arranged upstream of the first burner 1210, so that the blast air and the gas flow along the air outlet channel 1300 and flow through the corner 1350, so that the blast air and the gas are reversed, which is conducive to further mixing and reducing the speed of the blast air and the gas, and improving the uniformity and stability of the blast air and the gas ejected from the first burner 1210

[0056] Combination Fig. 9 As shown, in some embodiments, the fire cover 1000 is provided with an air outlet channel 1300, and the air outlet channel 1300 includes a second flow segment 1320 and a third flow segment 1330, the third flow segment 1330 is arranged downstream of the second flow segment 1320, and a step surface 1340 is arranged between the third flow segment 1330 and the second flow segment 1320, and the end of the third flow segment 1330 constitutes a first fire port 1210.

[0057] Specifically, the blast air and the gas enter the burner 100, and then flow through the gas outlet channel 1300 from the burner 100, and finally the blast air and the gas are ejected from the first burner 1210, ignited and form a flame. The inventor found that although the blast air can achieve full combustion of the gas, the blast air causes the gas flow rate ejected from the first burner 1210 to be relatively large, and the speed at which the gas leaves the first burner 1210 is greater than the combustion speed of the gas, which easily causes the flame-lifting phenomenon. Therefore, in this embodiment, the flame-lifting phenomenon of the first burner 1210 is suppressed by improving the gas outlet channel 1300. Specifically, the gas outlet channel 1300 includes a second flow segment 1320 and a third flow segment 1330. The third flow segment 1330 is arranged downstream of the second flow segment 1320. That is, when the gas flows along the gas outlet channel 1300, the gas flows through the second flow segment 1320 and the third flow segment 1330 in sequence. The end of the third flow segment 1330 constitutes the first flame port 1210, and finally ejects from the first flame port 1210. A step surface 1340 is arranged between the second flow segment 1320 and the third flow segment 1330. The setting of the step surface 1340 forms an angle space between the step surface 1340 and the second flow segment 1320 or the third flow segment 1330. When the gas flows through the step surface 1340, a vortex is formed at the corresponding position (angle space) of the step surface 1340. The vortex pulls the fast-flowing gas and decelerates the gas, thereby suppressing the flame separation phenomenon of the first burner 1210 and achieving a good flame stabilization effect. Through such a setting, the gas ejected from the first burner 1210 can be in oxygen-rich combustion and the flame separation phenomenon can be suppressed, which is beneficial to improving combustion efficiency.

[0058] Combination Fig. 9 As shown, in some embodiments, the step surface 1340 is perpendicular to the inner wall of the second flow segment 1320 and the inner wall of the third flow segment 1330. By such a setting, the angle space formed is a right-angle space, thereby strengthening the pulling effect of the formed vortex and further improving the flame stabilization effect.

[0059] Combination Fig. 9 As shown, in some embodiments, the cross-sectional area of ​​the second flow segment 1320 is smaller than the cross-sectional area of ​​the third flow segment 1330. It can be understood that the cross-sectional area refers to the area of ​​the through-flow cross section, which is perpendicular to the flow direction of the gas. The cross-sectional area of ​​the third flow segment 1330 is designed to be larger, and when the gas flows from the second flow segment 1320 to the third flow segment 1330 along the gas outlet channel 1300, the gas flow rate is further slowed down, and the flame stabilization effect is further improved with the effect of the vortex.

[0060] Combination Fig. 9As shown, in some embodiments, the gas outlet channel 1300 further includes a first flow segment 1310, which is disposed upstream of the second flow segment 1320, and the first flow segment 1310 and the second flow segment 1320 intersect to form a corner 1350. The first flow segment 1310 is disposed upstream of the second flow segment 1320, and along the direction of gas flow, the first flow segment 1310, the second flow segment 1320, and the third flow segment 1330 are arranged in sequence, that is, the gas flows through the first flow segment 1310, the second flow segment 1320, and the third flow segment 1330 in sequence, and is ejected from the first burner 1210. The corner 1350 is formed by the intersection between the first flow segment 1310 and the second flow segment 1320. When the gas flows from the first flow segment 1310 to the second flow segment 1320, it needs to pass through the corner 1350, that is, when the gas flows from the first flow segment 1310 to the second flow segment 1320, it needs to turn, which is conducive to further mixing and reducing the speed of the gas, and improving the uniformity and stability of the gas ejected from the first burner 12101231. Fig. 9 As shown, the first flow segment 1310 extends in the horizontal direction, the second flow segment 1320 extends in the vertical direction, a step surface 1340 is provided between the third flow segment 1330 and the second flow segment 1320, and the third flow segment 1330 extends in the vertical direction from the second flow segment 1320. It can be understood that since the end of the gas outlet channel 1300 (the end of the third flow segment 1330) forms the first burner 1210, and the first burner 1210 is provided on the fire cover 1000, the gas outlet channel 1300 is also provided on the fire cover 1000.

[0061] In some embodiments, the flame generated by the second burner 1220 is suitable for stabilizing the flame of the first burner 1210. Specifically, since the second burner 1220 ejects induced air and gas, the induced air is naturally induced by spraying gas from a nozzle, and does not need to be generated based on fluid machinery, the speed at which the gas leaves the second burner 1220 is not much different from the combustion speed of the gas, and stable combustion can be achieved, that is, the flame state formed by the second burner 1220 is stable, and since the flame formed by the second burner 1220 is more stable, the flame generated by the second burner 1220 can be used to stabilize the flame of the first burner 1210.

[0062] That is to say, in addition to heating the cookware, the flame formed by the second burner 1220 also serves as a flame stabilizing hole / flame stabilizing groove. In summary, since the second burner 1220 is used to inject air and gas, the gas ejected from the second burner 1220 has a more stable combustion state. By adjusting the position, angle or distance of the second burner 1220 and the first burner 1210, the flame formed by the second burner 1220 ignites the gas ejected from the first burner 1210 (such as the flame formed by the second burner 1220 heats the root of the gas ejected from the first burner 1210 and thus ignites the gas ejected from the first burner 1210). When the gas quickly leaves the first burner 1210, it is ignited by the flame formed by the second burner 1220. In this way, the gas that quickly leaves the first burner 1210 burns at the first burner 1210, thereby suppressing the occurrence of flame separation in the first burner 1210, stabilizing the flame for the first burner 1210, and further improving the combustion efficiency.

[0063] In some embodiments, the burner 100 includes a plurality of first burners 1210, where a plurality means two or more, i.e., the number of the first burners 1210 is at least two, and the plurality of first burners 1210 are arranged alternately in a ring shape, for example, the plurality of first burners 1210 are arranged alternately in a ring shape along the circumference of the burner 100, where the circumference can be understood as the direction surrounding the center of the burner 100, and the plurality of first burners 1210 eject gas to generate flames, which can achieve large-scale heating of the cooker. In addition to the above, it can also be combined with Figure 1 and Figure 2 As shown, in some embodiments, the first burner 1210 is in the shape of an annular seam, and the annular seam-shaped first burner 1210 can also achieve large-scale heating of the cooker, and when the first burner 1210 is designed to be in the shape of an annular seam, the first burner 1210 is continuous along the circumference of the burner 100, so that the excess oxygen in the gas ejected from the first burner 1210 can increase the contact with the fuel gas ejected from the second burner 1220, thereby further improving the oxygen supplement effect on the gas ejected from the second burner 1220.

[0064] Combination Figure 1 and Figure 2As shown, in some embodiments, the burner 100 includes a plurality of second burners 1220, and a plurality means two or more, that is, the number of the second burners 1220 is at least two, and the plurality of second burners 1220 are arranged alternately in an annular manner, for example, the plurality of second burners 1220 are arranged alternately in an annular manner along the circumference of the burner 100, and the circumference can be understood as the direction surrounding the center of the burner 100, and the plurality of second burners 1220 eject gas to generate flames, which can achieve large-scale heating of the cooker. In addition to the above situation, in some embodiments, the second burner 1220 is in the shape of an annular seam, and the annular seam-shaped second burner 1220 can also achieve large-scale heating of the cooker.

[0065] The first burner 1210 may be designed to be away from the center of the burner 100 relative to the second burner 1220 (see Figure 1 and Figure 2 ), the second burner 1220 can also be designed to be away from the center of the burner 100 relative to the first burner 1210 (not shown in the figure), the center of the burner 100 refers to the center of the firing range of the burner 100, when the first burner 1210 is further away from the center of the burner 100, observed from top to bottom, the first burner 1210 is closer to the outside and the second burner 1220 is closer to the inside, when the second burner 1220 is further away from the center of the burner 100, observed from top to bottom, the first burner 1210 is closer to the inside and the second burner 1220 is closer to the outside.

[0066] When the first burner 1210 is further away from the center of the burner 100, and when the first burner 1210 includes multiple and is arranged in an annular shape, the multiple first burners 1210 surround the second burner 1220 (the second burner 1220 may be multiple or in an annular shape), and when the first burner 1210 is in an annular shape, the annular first burner 1210 surrounds the second burner 1220 (the second burner 1220 may be multiple or in an annular shape). When the second burner 1220 is further away from the center of the burner 100, and when the second burner 1220 includes multiple and is arranged in an annular shape, the multiple second burners 1220 surround the first burner 1210 (the first burner 1210 may be multiple or in an annular shape), and when the second burner 1220 is in an annular shape, the annular second burner 1220 surrounds the first burner 1210 (the first burner 1210 may be multiple or in an annular shape).

[0067] The first burner 1210 and the second burner 1220 eject corresponding gases by the following scheme: Figures 1 to 5 as well as Fig.10As shown, in some embodiments, the burner head 2000 is provided with a first cavity 2110 and a second cavity 2120, the first cavity 2110 is communicated with the first burner 1210, the second cavity 2120 is communicated with the second burner 1220, the first cavity 2110 is used to receive blast air and gas, and the second cavity 2120 is used to receive ejection air and gas. The burner 100 includes a first ejection tube 3100 and a second ejection tube 3200, the first ejection tube 3100 is connected to the burner head 2000 so as to communicate with the first cavity 2110, the second ejection tube 3200 is connected to the burner head 2000 so as to communicate with the second cavity 2120, the air inlet end 3110 of the first ejection tube 3100 cooperates with the nozzle and is used to receive blast air, and the air inlet end 3210 of the second ejection tube 3200 cooperates with the nozzle.

[0068] The first ejector tube 3100 has a Venturi structure, and the air inlet end 3110 of the first ejector tube 3100 cooperates with the nozzle, that is, the nozzle sprays the gas at the air inlet end 3110 of the first ejector tube 3100, and at the same time, the blast air enters through the air inlet end 3110 of the first ejector tube 3100, for example, by forced blasting by the fan 4000, and the blast air and the gas are transported to the first cavity 2110, and finally ejected from the first burner 1210. It can be understood that the fan 4000 can be connected and fixed to the first ejector tube 3100, which is more convenient for the fan 4000 to cooperate with the air inlet end 3110 of the first ejector tube 3100. The second ejector tube 3200 has a Venturi structure, and the air inlet end 3210 of the second ejector tube 3200 cooperates with the nozzle, that is, the nozzle is aimed at the air inlet end 3210 of the second ejector tube 3200 to spray the fuel gas. At the same time, a negative pressure is formed on the surrounding environment to eject the air. The ejected air and the fuel gas are transported to the second cavity 2120 for mixing and finally ejected from the second burner 1220.

[0069] The second aspect of the present application discloses a gas stove, Figures 1 to 10As shown, the gas stove includes the above-mentioned burner 100, and the burner 100 includes a first surface 1001, the first surface 1001 is a plane, and the first surface 1001 is provided with a first burner 1210 and a second burner 1220, the first burner 1210 is used for supplying blast air and gas to be sprayed, and the second burner 1220 is used for supplying induced air and gas to be sprayed. The first burner 1210 in the present technical solution is used for gas and blast air to be ejected, and the blast air provides sufficient oxygen to enable the gas ejected from the first burner 1210 to be fully burned, and the blast air can produce excess oxygen to assist the combustion of the gas ejected from the second burner 1220, so that the gas ejected from the second burner 1220 can also be fully burned under the action of the induced air and the excess oxygen provided by the blast air. Through such an arrangement, the gas ejected from the first burner 1210 and the second burner 1220 can eventually be fully burned with high combustion efficiency, which is beneficial to the improvement of the thermal efficiency of the gas stove, and the first burner 1210 and the second burner 1220 are arranged on the first surface 1001, and the first surface 1001 is a plane, which is convenient for cleaning the fire cover 1000 and avoiding blockage of the first burner 1210 and the second burner 1220.

[0070] In some embodiments, the gas stove includes a valve body (not shown in the figure), which is used to adjust the amount of gas. When the valve body interrupts the gas supply to the first burner 1210, the valve body can maintain the gas supply to the second burner 1220, and at this time the fan 4000 is still in working condition.

[0071] Specifically, the valve body is a device for adjusting the gas flow rate. The inlet of the valve body is connected to the gas pipeline, and the outlet of the valve body is connected to the nozzle. The amount of gas that eventually leads to the first burner 1210 and the second burner 1220 is adjusted through the regulating function of the valve body. The specific structure of the valve body can be found in the relevant technology and will not be described in detail here. When the valve body is adjusted until the gas supply to the first burner 1210 is interrupted, the gas to the second burner 1220 can still be maintained, and the fan 4000 is also in working state at this time. In this way, the air (blast air) forcibly transported by the fan 4000 is ejected through the first burner 1210 and supplemented to the gas ejected from the second burner 1220, ensuring that the gas ejected from the second burner 1220 can also be fully burned when the gas is not ejected through the first burner 1210. It is understandable that the fan 4000 can be started synchronously when the gas stove is ignited. No matter how the valve body is adjusted, the fan 4000 remains in operation until the gas stove is turned off. Of course, other control logics can also be used, which will not be elaborated here.

[0072] The third aspect of the present application discloses an integrated appliance, which includes the gas stove of the above embodiment. The so-called integrated appliance is a device that integrates the gas stove and another traditional electrical function. For example, at least one of a microwave oven, an oven, a steamer, and a range hood can be integrated with the gas stove to form an integrated appliance. Of course, the integrated appliance is not limited to the aforementioned appliances. As long as it can achieve more functions than a single gas stove when integrated with the gas stove, it can be regarded as an integrated appliance. It can be understood that the gas stove of the integrated appliance of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0073] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
