[0046] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the drawings).

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0049] In addition, in the present application, descriptions such as "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0050] In the related art, a 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. The gas passes through the valve body and is ejected through a nozzle. The gas ejected from the nozzle is sprayed into the interior of the burner. During the process of the gas being sprayed into the interior of the burner, the entrainment of air is synchronously achieved. For the entrainment of air, reference can be made to the related art, which is generally based on the Venturi principle. During the process of the gas being sprayed into the interior of the burner, a negative pressure is formed on the surrounding environment, so that the air in the surrounding environment is synchronously entrained into the interior of the burner along with the ejection of the gas (the air that enters the interior of the burner through the entrainment action is called entrained air, and the entrained air is primary air). After the entrained air and the gas are mixed in the interior of the burner, they are ejected from the interior of the burner and then ignited to form a flame. During the combustion of the gas, through the buoyancy and entrainment effects, the surrounding environment will supply 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 full combustion of the ejected gas. However, the amount of primary air is affected by the structure and working conditions, and the supplement of secondary air depends on the buoyancy and entrainment effects, which is a passive supplement and has high requirements for the dimensions of the components. Therefore, the gas mostly burns in a state of lean oxygen combustion and is not fully burned only by entrained air and entraining the air in the surrounding environment. To solve this problem, the present application improves the burner to at least to some extent enhance the combustion degree of the gas, thereby being beneficial to the improvement of the thermal efficiency of the gas stove.

[0051] Combined with Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in

[0052] The burner 100 will be described below in combination with the gas stove. It can be understood that in addition to being applied to the gas stove, the burner 100 can also be applied to other devices that work through gas combustion.

[0053] Specifically, the second burner orifice 1141 is used for ejecting induced air and gas, that is, the induced air and gas enter the interior of the burner 100, and then are ejected from the interior of the burner 100 through the second burner orifice 1141 and are ignited to form a flame. Similar to the description above, 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 sprayed into the interior of the burner 100. During the process of the gas being sprayed into the interior of the burner 100, the induction of air is synchronously achieved, so that the induced air follows the gas into the interior of the burner 100, and then the induced air and the gas are ejected from the second burner orifice 1141.

[0054] The first burner orifice 1131 is used for ejecting blast air and gas, that is, the blast air and gas enter the interior of the burner 100, and then are ejected from the interior of the burner 100 through the first burner orifice 1131 and are ignited to form a flame. Similar to the description above, 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 sprayed into the interior of the burner 100. During this process, blast air is provided. The blast air is generated by a fluid machine, for example, the blast air is provided by the forced blast of the blower 4000. 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 orifice 1131 with the gas. Compared with the induced air, the blast air can provide enough oxygen, so that the gas ejected from the first burner orifice 1131 is in a state of rich-oxygen combustion, thereby enabling the gas ejected from the first burner orifice 1131 to burn sufficiently (the flame generated by the first burner orifice 1131 can still entrain the secondary air in the surrounding environment to participate in combustion).

[0055] If the gas ejected from the second burner orifice 1141 depends only on the induced air and the entrained air in the surrounding environment, it is not sufficient to burn sufficiently. Since the blast air is ejected from the first burner orifice 1131, it can provide enough oxygen. In addition to participating in the combustion of the gas ejected from the first burner orifice 1131, the excess oxygen in the blast air can also be supplemented into the gas ejected from the second burner orifice 1141 to assist the combustion of the gas ejected from the second burner orifice 1141. Compared with supplementing the secondary air from the surrounding environment by the entrainment effect, the excess oxygen provided by the blast air ejected from the first burner orifice 1131 is more actively supplemented into the gas ejected from the second burner orifice 1141, enabling the gas ejected from the second burner orifice 1141 to burn sufficiently (the flame generated by the second burner orifice 1141 can still entrain the secondary air in the surrounding environment to participate in combustion).

[0056] Through the above solution, the gas ejected from the first burner port 1131 and the second burner port 1141 burns sufficiently, with high combustion efficiency, which is beneficial to improving the thermal efficiency of the gas stove. It can be understood that the sufficient combustion mentioned in this article refers to the combustion state relative to the state where only the entrained air and the air in the surrounding environment are relied on (that is, relatively more sufficient).

[0057] In addition, the inventor found that although sufficient combustion of the gas can be achieved by blowing air, due to the action of blowing air, the gas flow velocity of the gas ejected from the first burner port 1131 is relatively large, and the velocity of the gas leaving the first burner port 1131 is greater than the combustion velocity of the gas, which is prone to the phenomenon of flame lift. Since the gas ejected from the second burner port 1141 is the entrained air and the gas, and the entrained air is naturally entrained by ejecting the gas through the nozzle and does not need to be generated based on a fluid machine, the velocity of the gas leaving the second burner port 1141 is not much different from the combustion velocity of the gas, and stable combustion can be achieved, that is, the flame state formed by the second burner port 1141 is stable. Since the flame formed by the second burner port 1141 is more stable, the flame generated by the second burner port 1141 can be used to stabilize the flame of the first burner port 1131.

[0058] That is to say, in addition to heating the cooking utensil, the flame formed by the second burner port 1141 also acts as a flame stabilizing hole / flame stabilizing groove. Generally speaking, since the second burner port 1141 ejects the entrained air and the gas, the gas ejected from the second burner port 1141 has a more stable combustion state. By adjusting the position, angle or distance between the second burner port 1141 and the first burner port 1131, etc., the flame formed by the second burner port 1141 ignites the gas ejected from the first burner port 1131 (for example, the flame formed by the second burner port 1141 heats the root of the gas ejected from the first burner port 1131 to ignite the gas ejected from the first burner port 1131). When the gas quickly leaves the first burner port 1131, it is ignited by the flame formed by the second burner port 1141, so that the gas that quickly leaves the first burner port 1131 burns at the first burner port 1131, thereby suppressing the occurrence of the flame lift phenomenon of the first burner port 1131 and playing a role in stabilizing the flame of the first burner port 1131, and further improving the combustion efficiency. In this embodiment, the deflector 1200 is arranged on the gas outlet path of the second burner port 1141, and the flame formed by the ejection of the entrained air and the gas from the second burner port 1141 is blocked by the deflector 1200 and then deformed along the deflector 1200. The deflector 1200 guides the flame generated by the second burner port 1141 to the first burner port 1131, which is beneficial to burning the root of the gas ejected from the first burner port 1131, so that the gas that quickly leaves the first burner port 1131 can be efficiently ignited, and the occurrence of the flame lift phenomenon of the first burner port 1131 is suppressed.

[0059] Combined with Figures 14 to 17As shown, in some embodiments, the flow deflector 1200 is further disposed on the gas outlet path of the first burner port 1131. As can be known from the above, the first burner port 1131 is used for the blast air and the gas to be ejected. By providing the flow deflector 1200, when the blast air and the gas are ejected from the first burner port 1131, they will encounter the obstruction of the flow deflector 1200. The flow deflector 1200 plays a buffering role for the excess oxygen in the blast air, and the excess oxygen in the blast air will also diverge when encountering the obstruction of the flow deflector 1200, so that it is easier to supplement the gas ejected from the second burner port 1141 and participate in combustion, achieving efficient mixing and further improving the combustion efficiency.

[0060] Combined with Figures 7 to 10 and Figures 14 to 17 As shown, in some embodiments, the second burner port 1141 is disposed below the first burner port 1131. The orientation in this text is referenced with the gas stove in the installation environment. The side close to the ground is the lower (bottom), and the side away from the ground is the upper (top). That is, the second burner port 1141 is relatively lower than the first burner port 1131. The flame formed by the first burner port 1131 and the second burner port 1141 will be generated upward. When the position of the first burner port 1131 is higher, in cooperation with the flow deflector 1200, the flame generated by the second burner port 1141 is more likely to contact the root of the gas (gas) ejected from the first burner port 1131.

[0061] Combined with Figures 7 to 11 and Figures 14 to 17 As shown, in some embodiments, the burner cap 1100 includes an annular wall surface 1150. The annular wall surface 1150 surrounds the center of the burner 100. The center of the burner 100 refers to the center of the fire outlet range of the burner 100. The first burner port 1131 and the second burner port 1141 are disposed on the annular wall surface 1150. One of the flow deflector 1200 and the annular wall surface 1150 surrounds the other, so that a combustion chamber 1300 is defined between the flow deflector 1200 and the annular wall surface 1150, and the top of the combustion chamber 1300 is open.

[0062] Specifically, there are various ways of the cooperation between the burner cap 1100 and the flow deflector 1200. For example, the flow deflector 1200 is annular, and the burner cap 1100 surrounds the flow deflector 1200. The inner wall of the burner cap 1100 constitutes the annular wall surface 1150, so that the annular wall surface 1150 surrounds the flow deflector 1200, and a combustion chamber 1300 is defined between the annular wall surface 1150 and the flow deflector 1200, and the combustion chamber 1300 is also annular. It can also be that the flow deflector 1200 surrounds the burner cap 1100, and the outer wall of the burner cap 1100 constitutes the annular wall surface 1150, so that the flow deflector 1200 surrounds the annular wall surface 1150, and a combustion chamber 1300 is defined between the flow deflector 1200 and the annular wall surface 1150, and the burner 100 is also annular.

[0063] When the second burner port 1141 is disposed below the first burner port 1131, the deflector 1200 may correspond only to the second burner port 1141, that is, the second burner port 1141 ejects gas toward the combustion chamber 1300 and is ignited, while the first burner port 1131 does not need to eject gas toward the combustion chamber 1300. In this case, the deflector 1200 guides the flame generated by the second burner port 1141 to the first burner port 1131. Of course, the deflector 1200 may correspond to both the second burner port 1141 and the first burner port 1131, that is, the second burner port 1141 ejects gas toward the burner 100 and is ignited, and the first burner port 1131 also ejects gas toward the combustion chamber 1300 and is ignited. On the premise of ensuring that the deflector 1200 guides the flame generated by the second burner port 1141 to the first burner port 1131, the excess oxygen ejected by the first burner port 1131 is more efficiently mixed with the gas ejected by the second burner port 1141 in the combustion chamber 1300. It can be understood that the top of the combustion chamber 1300 is open, so that the flame in the combustion chamber 1300 penetrates from the top of the combustion chamber 1300, thereby heating the cooking utensil.

[0064] Combined with Figures 7 to 10 As shown, in some embodiments, the annular wall surface 1150 surrounds the deflector 1200, and the annular wall surface 1150 is designed to be gradually expanding from bottom to top. Specifically, the first burner port 1131 and the second burner port 1141 are disposed on the annular wall surface 1150, and the annular wall surface 1150 is designed to be gradually expanding from bottom to top. In this way, it is beneficial for heat to radiate upward (toward the cooking utensil), improving the heating effect on the cooking utensil. In particular, in order to match the shape of the annular wall surface 1150, the deflector 1200 is also designed to be gradually expanding from bottom to top to ensure that the flame of the second burner port 1141 is guided to the first burner port 1131.

[0065] Combined with Figure 3 、 Figure 4 and Figure 11 As shown, in some embodiments, along the axial direction of the burner 100, the minimum distance between the second burner port 1141 and the first burner port 1131 is not greater than 15 mm, and along the radial direction of the burner 100, the minimum distance between the second burner port 1141 and the first burner port 1131 is not greater than 10 mm.

[0066] Specifically, taking the example that the first burner port 1131 is higher than the second burner port 1141, the axial direction of the burner 100 is the up-and-down direction (the gas stove is in a horizontal installation state), and the radial direction is the direction passing through the center of the burner 100 and perpendicular to the axial direction. In this embodiment, along the axial direction of the burner 100, the minimum distance between the second burner port 1141 and the first burner port 1131 is L1, and L1 is not greater than 15 mm. For example, L1 is 15 mm, 12 mm, 9 mm, 5 mm, 2 mm or 1 mm. Along the radial direction of the burner 100, the minimum distance between the second burner port 1141 and the first burner port 1131 is L2, and L2 is not greater than 10 mm. For example, L2 is 10 mm, 8 mm, 6 mm, 4 mm, 2 mm or 1 mm. After a large number of tests by the inventor, when L1 and L2 meet the above conditions, the flame stabilizing effect of the second burner port 1141 on the first burner port 1131 is better, reducing the influence of the shapes and sizes of the second burner port 1141 and the first burner port 1131, and meeting more styling designs of the burner 100.

[0067] Combined with Figure 1 , Figure 2 and Figures 7 to 10 As shown, in some embodiments, the burner 100 is further provided with an annular groove 1160, and the annular groove 1160 extends along the annular wall surface 1150, that is, the annular groove 1160 surrounds the center of the burner 100, and the annular groove 1160 is arranged between the first burner port 1131 and the second burner port 1141. The annular groove 1160 is connected and communicated with the first burner port 1131, and the excess oxygen ejected from the first burner port 1131 enters the annular groove 1160. Since the annular groove 1160 surrounds the center of the burner 100, the mixing of the excess oxygen ejected from the first burner port 1131 and the gas ejected from the second burner port 1141 can be enhanced in this way, further improving the oxygen supply effect on the gas ejected from the second burner port 1141. For example, the first burner port 1131 is located above the annular groove 1160, the second burner port 1141 is located below the annular groove 1160, and the first burner port 1131 includes a plurality of them and is arranged in a surrounding manner, and the annular groove 1160 is continuous along the circumferential direction of the burner 100, so that the oxygen supply to the second burner port 1141 can be enhanced.

[0068] Combined with Figures 7 to 11As shown, in some embodiments, the burner cap 1100 includes a first burner cap 1110 and a second burner cap 1120. For example, the burner 100 includes a burner head 2000, and the burner cap 1100 is disposed on the burner head 2000. The burner head 2000 can be integrally formed or assembled by connecting split components through connection means. The cooperation between the burner cap 1100 and the burner head 2000 can be such that the first burner cap 1110 is placed on the burner head 2000 under the action of gravity, the second burner cap 1120 is placed on the burner head 2000 under the action of gravity, and the first burner cap 1110 surrounds the second burner cap 1120, thus realizing the mutual cooperation between the first burner cap 1110 and the second burner cap 1120.

[0069] Continuing in conjunction with Figures 7 to 11 As shown, a first fire port 1131 is provided between the first burner cap 1110 and the second burner cap 1120, and the second burner cap 1120 is provided with a second fire port 1141. Similarly, the annular groove 1160 can also be formed by the cooperation between the first burner cap 1110 and the second burner cap 1120.

[0070] In conjunction with Figure 1 and Figure 2 As shown, in some embodiments, the burner 100 includes a plurality of first fire ports 1131. The term "plurality" means two or more, that is, the number of the first fire ports 1131 is at least two. The plurality of first fire ports 1131 are arranged in an annular and alternating manner. For example, the plurality of first fire ports 1131 are arranged in an annular and alternating manner along the circumferential direction of the burner 100. The circumferential direction can be understood as the direction surrounding the center of the burner 100. The plurality of first fire ports 1131 eject gas to generate flames, which can realize large-range heating of the cooking utensils. In addition to the above situation, in some embodiments, the first fire port 1131 is in the shape of an annular slit. The annular-slit-shaped first fire port 1131 can also realize large-range heating of the cooking utensils. And when the first fire port 1131 is designed in the shape of an annular slit, the first fire port 1131 is continuous along the circumferential direction of the burner 100. Thus, the excess oxygen in the gas ejected from the first fire port 1131 can increase the contact with the gas ejected from the second fire port 1141, improving the oxygen supply effect on the gas ejected from the second fire port 1141.

[0071] In conjunction with Figure 1 and Figure 2As shown, in some embodiments, the burner 100 includes a plurality of second burner ports 1141. The term "plurality" means two or more, that is, the number of the second burner ports 1141 is at least two. The plurality of second burner ports 1141 are arranged in an annular and alternating pattern. For example, the plurality of second burner ports 1141 are arranged in an annular and alternating pattern along the circumferential direction of the burner 100. The circumferential direction can be understood as the direction around the center of the burner 100. The plurality of second burner ports 1141 eject gas to generate flames, which can achieve large-range heating of the cooking utensil. In addition to the above situation, it can also be that, in some embodiments, the second burner port 1141 is in the shape of an annular slit, and the annular-slit-shaped second burner port 1141 can also achieve large-range heating of the cooking utensil.

[0072] The first burner port 1131 is designed to be farther from the center of the burner 100 than the second burner port 1141, that is, when observing the burner 100 from top to bottom, the first burner port 1131 is more outward relative to the second burner port 1141, and the second burner port 1141 is more inward relative to the first burner port 1131 (the minimum distance between the first burner port 1131 and the center of the burner 100 is greater than the minimum distance between the second burner port 1141 and the center of the burner 100). When there are multiple first burner ports 1131, the multiple first burner ports 1131 surround the second burner port 1141 (at this time, the second burner port 1141 can be multiple or in the shape of an annular slit). When the first burner port 1131 is in the shape of an annular slit, the first burner port 1131 surrounds the second burner port 1141 (at this time, the second burner port 1141 can be multiple or in the shape of an annular slit).

[0073] On the premise that the number of the first burner ports 1131 is multiple and the number of the second burner ports 1141 is multiple, in combination with Figure 6 , Figure 9 , Figure 10 , Figure 12 and Figure 13 As shown, the burner 100 includes a first channel 1130 and a second channel 1140. The end of the first channel 1130 forms the first burner port 1131, and the end of the second channel 1140 forms the second burner port 1141. Since the number of the first burner ports 1131 and the number of the second burner ports 1141 are multiple, it means that the number of the first channels 1130 and the number of the second channels 1140 are also multiple. For example, the burner 100 includes a burner cap 1100. The burner cap 1100 is provided with the first channel 1130 and the second channel 1140, thereby forming the first burner port 1131 and the second burner port 1141. The blast air and the gas are transmitted along the first channel 1130 and finally ejected from the first burner port 1131, and the entrained air and the gas are transmitted along the second channel 1140 and finally ejected from the second burner port 1141.

[0074] In this embodiment, the multiple first channels 1130 are arranged in a rotational pattern in a first direction, and the multiple second channels 1140 are arranged in a rotational pattern in a second direction, and the first direction is opposite to the second direction. For exampleFigure 12 and Figure 13 For the burner 100 shown, a plurality of first channels 1130 are arranged in a clockwise rotation. The so-called clockwise rotation arrangement means that the gas ejected from the plurality of first burner ports 1131 instantaneously flows clockwise as a whole. A plurality of second channels 1140 are arranged in a counterclockwise rotation. The so-called counterclockwise rotation arrangement means that the gas ejected from the plurality of second burner ports 1141 instantaneously flows counterclockwise as a whole. Due to the different rotation arrangement directions of the plurality of first channels 1130 and the plurality of second channels 1140, the directions of the gas ejected from the first burner ports 1131 and the gas ejected from the second burner ports 1141 are different, which is beneficial to the mixing of the gas and then enhances the effect of complete combustion.

[0075] Combined with Figure 5 and Figure 7 As shown, in some embodiments, the burner head 2000 is provided with a first cavity 2100 and a second cavity 2200. For example, the first cavity 2100 surrounds the second cavity 2200. The burner cap 1100 is disposed on the burner head 2000 to cover the first cavity 2100 and the second cavity 2200. The first burner ports 1131 communicate with the first cavity 2100, and the second burner ports 1141 communicate with the second cavity 2200. The first cavity 2100 is used to receive blast air and gas, and the second cavity 2200 is used to receive induced air and gas. The blast air and gas are introduced into the first cavity 2100 for mixing and then ejected from the first burner ports 1131 and ignited to form a flame. The induced air and gas are introduced into the second cavity 2200 for mixing and then ejected from the second burner ports 1141 and ignited to form a flame.

[0076] The first cavity 2100 and the second cavity 2200 receive the corresponding gases through the cooperation of the first ejector tube 3100 and the second ejector tube 3200. Combined with Figure 1 As shown, in some embodiments, the burner 100 includes a first ejector tube 3100 and a second ejector tube 3200. The first ejector tube 3100 is connected to the burner head 2000 so as to communicate with the first cavity 2100. The second ejector tube 3200 is connected to the burner head 2000 so as to communicate with the second cavity 2200. The intake end 3110 of the first ejector tube 3100 cooperates with the nozzle and is used to receive blast air. The intake end 3210 of the second ejector tube 3200 cooperates with the nozzle.

[0077] Specifically, the first ejector tube 3100 has a Venturi structure. The air inlet end 3110 of the first ejector tube 3100 is matched with the nozzle, that is, the nozzle is aligned with the air inlet end 3110 of the first ejector tube 3100 to inject fuel gas. At the same time, the blast air enters through the air inlet end 3110 of the first ejector tube 3100, for example, realized by forced blast through the blower 4000. The blast air and the fuel gas are transported to the first cavity 2100 for mixing and finally ejected from the first burner port 1131. It can be understood that the blower 4000 can be fixedly connected to the first ejector tube 3100, which is more convenient for the cooperation between the blower 4000 and the air inlet end 3110 of the first ejector tube 3100. The second ejector tube 3200 has a Venturi structure. The air inlet end 3210 of the second ejector tube 3200 is matched with the nozzle, that is, the nozzle is aligned with the air inlet end 3210 of the second ejector tube 3200 to inject fuel gas. At the same time, a negative pressure is formed on the surrounding environment to eject air. The ejected air and the fuel gas are transported to the second cavity 2200 for mixing and finally ejected from the second burner port 1141.

[0078] The second aspect of the present application discloses a gas stove, which combines Figures 1 to 17 As shown, the gas stove includes the above-mentioned burner 100. The burner 100 includes a burner cap 1100 and a baffle 1200. The burner cap 1100 is provided with a first burner port 1131 and a second burner port 1141. The first burner port 1131 is used for the blast air and the fuel gas to be ejected, and the second burner port 1141 is used for the ejected air and the fuel gas to be ejected. The baffle 1200 is arranged on the gas outlet path of the second burner port 1141, and the baffle 1200 is used to direct the flame generated by the second burner port 1141 to the first burner port 1131. It can be understood that the burner 100 of the gas stove in this embodiment adopts the technical solution of the above embodiment, and thus has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0079] In some embodiments, the gas stove includes a valve body (not shown in the figure). The valve body is used to adjust the fuel gas volume. When the fuel gas supply to the first burner port 1131 is interrupted in the valve body, the valve body can maintain the fuel gas supply to the second burner port 1141, and at this time, the blower 4000 is still in the working state.

[0080] Specifically, the valve body is a device for regulating the gas flow. The inlet of the valve body is connected to the gas pipeline, and the outlet of the valve body is connected to the nozzle. By adjusting the valve body, the gas volume finally leading to the first burner port 1131 and the second burner port 1141 can be adjusted. For the specific structure of the valve body, reference can be made to the related art and will not be elaborated here in detail. When the valve body is adjusted until the gas supply to the first burner port 1131 is interrupted, the gas supply to the second burner port 1141 can still be maintained. And at this time, the blower 4000 is also in the working state. Thus, the air (blast air) forcibly conveyed by the blower 4000 is ejected through the first burner port 1131 and supplemented into the gas ejected from the second burner port 1141, ensuring that the gas ejected from the second burner port 1141 can also burn fully when no gas is ejected through the first burner port 1131.

[0081] It can be understood that the blower 4000 can be started synchronously when the gas stove is ignited. No matter how the valve body is adjusted, the blower 4000 still remains in the running state until the gas stove is extinguished when the blower 4000 is turned off. Of course, other control logics can also be adopted and will not be elaborated one by one here.

[0082] The third aspect of the present application discloses an integrated appliance. The integrated appliance includes the gas stove of the above embodiment. The so-called integrated appliance is a device that integrates the functions of a gas stove and another traditional appliance. 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 appliances listed above. As long as it can achieve more functions when integrated with the gas stove compared to a single gas stove, it can be regarded as an integrated appliance. It can be understood that the gas stove of the integrated appliance in this embodiment adopts the technical solution of the above embodiment. Therefore, it has at least the beneficial effects brought by the technical solution of the above embodiment and will not be repeated here.

[0083] The above are only the preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structural transformation made under the concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
