[0030] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0031] Reference will be made below to Figures 1-4Describe a burner device 10 according to an embodiment of the present application. The burner device 10 includes a main body portion 11, a gas distribution plate assembly 12, and a mixing flow assembly 13. A combustion cavity 111 is formed inside the main body portion 11. The gas distribution plate assembly 12 has a gas distribution plate body 121 and a connecting pipe 122. The gas distribution plate body 121 is connected to the main body portion 11. The connecting pipe 122 is disposed on a side of the gas distribution plate body 121 facing away from the main body portion 11 and extends in a direction away from the gas distribution plate body 121. A mixing flow cavity 133 is formed inside the mixing flow assembly 13. The mixing flow cavity 133 communicates with the combustion cavity 111 through the gas distribution plate assembly 12. The mixing flow assembly 13 is connected to the free end of the connecting pipe 122; wherein the gas distribution plate body 121 and the connecting pipe 122 are configured as an integrally formed part.

[0032] Currently, burners usually adopt a fully premixed combustion mode. Fully premixed combustion means that before combustion, fuel and air are fully premixed. After forming a uniform mixture gas, combustion is carried out. In order to achieve uniform gas mixing, a gas mixing tank is required for mixing the gas. Subsequently, the gas in the gas mixing tank is introduced into the burner. Existing burners use a hose or a combined structure to transport the mixed gas, with low structural strength and short service life.

[0033] As Figure 1 shown, specifically, the burner device 10 includes a main body portion 11, a gas distribution plate assembly 12, and a mixing flow assembly 13. A combustion cavity 111 can be formed inside the main body portion 11. Fuel can be transported into the combustion cavity 111 and burned to generate heat and flue gas. Among them, the fuel can be a gas such as gas. The gas referred to here can be a mixed gas of gas and air. The gas distribution plate assembly 12 has a gas distribution plate body 121 and a connecting pipe 122. The gas distribution plate body 121 can be connected to the main body portion 11. Optionally, the gas distribution plate and the main body portion 11 can form a detachable connection through screws, bolts, or the gas distribution plate and the main body portion 11 can form a detachable connection through snap connection or plug connection, or the gas distribution plate and the main body portion 11 are directly welded and fixed through the contact surface.

[0034] The connecting pipe 122 can be arranged on the side of the gas distribution plate body 121 away from the main body portion 11, and the connecting pipe 122 can extend in a direction away from the gas distribution plate body 121. A mixing cavity 133 can be formed in the mixing component 13, and the mixing cavity 133 can communicate with the combustion cavity 111 through the gas distribution plate component 12. Specifically, the mixing component 13 can be connected to the free end of the connecting pipe 122, and the free end of the connecting pipe 122 can be the end of the connecting pipe 122 away from the gas distribution plate body 121. Further, the gas distribution plate body 121 and the connecting pipe 122 can be constructed as an integrally formed part. Adopting the above structure can improve the overall structural strength of the gas distribution plate component 12, prevent gas leakage during transportation, facilitate the processing of the gas distribution plate component 12, reduce the mold cost, and improve the service life of the burner device 10.

[0035] In short, the burner device 10 of the embodiment of the present application is provided with a main body portion 11 and a mixing component 13. A combustion cavity 111 for gas combustion is formed in the main body portion 11, and a mixing cavity 133 for mixing gas and air is formed in the mixing component 13. The combustion cavity 111 and the mixing cavity 133 can communicate through the gas distribution plate body 121 and the connecting pipe 122. The gas distribution plate body 121 and the connecting pipe 122 can be constructed as an integrally formed part. By constructing the gas distribution plate body 121 and the connecting pipe 122 as an integrally formed part, the internal stress distribution can be made more balanced, the overall structural strength and service life can be improved, the assembly difficulty can be reduced, the mold cost can be reduced, and the production efficiency can be improved.

[0036] As Figure 1 and Figure 2 shown, in some embodiments of the present application, the gas distribution plate component 12 further includes a cover body 123. The cover body 123 can be arranged at the free end of the connecting pipe 122, and the cover body 123 can be connected to the mixing component 13. Optionally, the cover body 123 and the mixing component 13 can be arranged opposite to each other and sealed, so as to close the mixing cavity 133, ensure the sealing of the mixing cavity 133, prevent the mixed gas from leaking from the connection between the cover body 123 and the mixing component 13, and improve the safety performance of the burner device 10.

[0037] Further, the cover body 123 and the connecting pipe 122 can be constructed as an integrally formed part. Similarly, adopting the above structure can improve the overall structural strength of the gas distribution plate component 12, facilitate the processing of the gas distribution plate component 12, and reduce the mold cost. It should be noted that on the basis that the gas distribution plate body 121 and the connecting pipe 122 are constructed as an integrally formed part, the cover body 123 and the connecting pipe 122 being constructed as an integrally formed part can be understood as the gas distribution plate body 121, the connecting pipe 122 and the cover body 123 being constructed as an integrally formed part, that is, the gas distribution plate component 12 is integrally constructed as an integrally formed part.

[0038] AsFigure 3 As shown, in some embodiments of the present application, the mixing component 13 includes a mixing housing 131 and a fan 132. A mixing cavity 133 can be formed inside the mixing housing 131, and the mixing housing 131 can have a connection end facing the main body portion 11 open. The cover body 123 can be connected to the connection end to close the connection end. Here, the locked closure is the connection between the cover body 123 and the connection end, ensuring that the gas after mixing inside the mixing cavity 133 can flow into the combustion cavity 111, and preventing gas leakage from the connection between the cover body 123 and the mixing housing 131. A gas inlet 134 and an air inlet 135 are also formed in the mixing housing 131. The gas inlet 134 and the air inlet 135 can communicate with the mixing cavity 133. It can be understood that the gas inlet 134 can be used to transport gas, and the air inlet 135 can be used to input air. After the air and gas enter the mixing cavity 133, they can be mixed.

[0039] As Figure 3 shown, in some embodiments, the gas inlet 134 and the air inlet 135 can be arranged facing each other. When the gas and air pass through the gas inlet 134 and the air inlet 135 respectively, they can directly contact and mix, thereby improving the mixing efficiency of the gas and air. The fan 132 can be arranged on the mixing housing 131. The fan 132 can introduce air into the air inlet 135 and enter the mixing cavity to mix with the gas. It should be noted that after the gas is mixed with the oxygen in the air, combustion can occur. By optimizing the mixing ratio of the gas and air, the sufficiency and efficiency of the combustion process can be ensured. It can be understood that an appropriate mixing ratio of the gas and air can maximize the energy released during the combustion process. Therefore, the use of the mixing component 13 can improve the combustion efficiency of the gas.

[0040] As Figure 2 and Figure 3 shown, in some embodiments of the present application, a first ear 1231 extending in the first direction can be formed on the cover body 123, and a second ear 1311 extending in the first direction is formed on the mixing housing 131. The second ear 1311 can be arranged facing the first ear 1231, and the second ear 1311 can be connected to the first ear 1231. Optionally, a detachable connection can be formed between the first ear 1231 and the second ear 1311 by screws or bolts. Alternatively, a detachable connection can be formed between the first ear 1231 and the second ear 1311 by snap connection or plug connection. Or the first ear 1231 and the second ear 1311 are directly welded and fixed through the contact surface.

[0041] In a specific embodiment, a first mounting hole penetrating in the thickness direction may be formed on the first ear 1231, and a second mounting hole penetrating in the thickness direction may be formed on the second ear 1311. The first mounting hole and the second mounting hole may be disposed opposite to each other in the thickness direction. The gas distribution plate assembly 12 may further include a fastener, and the fastener may pass through the first mounting hole and the second mounting hole to fixedly connect the first ear 1231 and the second ear 1311. The first ears 1231 may be configured as multiple ones spaced apart on the cover body 123, and the second ears 1311 may be configured as multiple ones and are disposed in one-to-one correspondence with the multiple first ears 1231. Using the multiple first ears 1231 and second ears 1311 can improve the fitting strength between the cover body 123 and the mixed-flow housing 131.

[0042] As Figure 2 and Figure 4 shown, in some embodiments of the present application, the burner device 10 further includes a flow equalizing plate 14. The flow equalizing plate 14 may be located inside the gas distribution plate body 121. A plurality of gas distribution holes 141 may be formed on the flow equalizing plate 14. Using the gas distribution holes 141 can make the flow of the fuel gas more uniform, thereby ensuring that the fuel gas can burn evenly after being ignited and the heating temperature uniformity is good. A first gas distribution area 142 and a second gas distribution area 143 may be formed on the flow equalizing plate 14. The first gas distribution area 142 and the second gas distribution area 143 are spaced apart from each other, and the first gas distribution area 142 is disposed opposite to the second communication hole. Among them, the diameter of the gas distribution holes 141 in the first gas distribution area 142 is smaller than the diameter of the gas distribution holes 141 in the second gas distribution area 143. Since the first gas distribution area 142 is disposed opposite to the second communication hole, the flow rate of the fuel gas at the first gas distribution area 142 is greater than the flow rate of the fuel gas at the second gas distribution area 143. Therefore, under the condition that the flow velocity of the fuel gas at the first gas distribution area 142 is greater than the flow velocity of the fuel gas at the second gas distribution area 143, by making the diameter of the gas distribution holes 141 in the first gas distribution area 142 smaller than the diameter of the gas distribution holes 141 in the second gas distribution area 143, it can be ensured that the gas throughput at each part of the flow equalizing plate 14 is uniform, so that the flame after the fuel gas is ignited can be evenly distributed. Further, the inner diameter of the gas distribution holes 141 in the second gas distribution area 143 gradually decreases in the direction away from the first gas distribution area 142, so as to ensure that the flow of the fuel gas at the flow equalizing plate 14 is more uniform.

[0043] As Figure 2 and Figure 3As shown, in some embodiments of the present application, a flow dividing rib 1211 is further formed on one side of the gas dividing plate body 121 facing the main body portion 11. The flow dividing rib 1211 can extend in a direction away from the mixing flow housing 131, and the free end of the flow dividing rib 1211 can abut against the flow equalizing plate 14. The flow dividing ribs 1211 can be non-uniformly arranged. The flow dividing ribs 1211 can play a role in dividing and guiding the gas, ensuring that the gas can flow through the corresponding gas distribution holes 141 between two adjacent flow dividing ribs 1211, and ensuring that the gas can burn more fully and evenly.

[0044] It should be noted that the non-uniform arrangement of the above-mentioned flow dividing ribs 1211 can be understood as that the arrangement positions of the flow dividing ribs 1211 are correspondingly set with the first gas distribution area 142 and the second gas distribution area 143. The gas flow rate in the first gas distribution area 142 is large. Therefore, the flow dividing ribs 1211 corresponding to the first gas distribution area 142 are relatively dispersed, ensuring that the mixed gas can flow from the first gas distribution area 142 to the second gas distribution areas 143 on both sides. The gas flow rate in the second gas distribution area 143 is small, and the flow dividing ribs 1211 corresponding to the second gas distribution area 143 are relatively compact, ensuring that the mixed gas can flow to the gas distribution holes 141 in the second gas distribution area 143 and preventing the gas from flowing to the first gas distribution area 142. The arrangement positions of the flow dividing ribs 1211 can be set according to the first gas distribution area 142 and the second gas distribution area 143.

[0045] In some embodiments of the present application, the connecting pipe 122 is configured such that the cross-sectional area gradually increases in the direction from the mixing flow assembly 13 to the gas dividing plate body 121. When the gas and air are mixed and pass through the connecting pipe 122, as the cross-sectional area of the connecting pipe 122 increases, the mixed gas diffuses more evenly into the inside of the flow dividing plate body, which is beneficial to the uniform distribution of the concentration field. And the flow rate of the mixed gas will also decrease when flowing through the connecting pipe 122, thereby reducing the frictional loss and energy loss between the mixed gas and the inner wall of the connecting pipe 122. Since gas is likely to generate vibration and noise when flowing through a pipe with a small inner diameter, therefore, adopting the above-mentioned connecting pipe 122 can also reduce the noise and vibration of the mixed gas when passing through the connecting pipe 122, thereby improving the stability and reliability of the connecting pipe 122.

Since the cooking system according to the embodiments of the present application is provided with the burner device 10 of the above embodiments, therefore, by forming the gas dividing plate body 121 and the connecting pipe 122 into an integrally formed part, the internal stress distribution of the burner device 10 in the cooking system can be made more balanced, improving the overall structural strength and service life, while reducing the assembly difficulty, reducing the mold cost, and improving the production efficiency.
