Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cooking device, especially a kind of burner assembly and cooking device for cooking device. BACKGROUND

[0002] Gas burner generally uses the way of ignition needle to generate electric arc to ignite. The ignition system includes a target side, which is equipped with a side wall, and its specific structure is designed to not hinder the normal injection of gas on one side of the burner flame opening. The design of the side wall also takes advantage of the flow rate reduction effect caused by it to optimize the ignition conditions.

[0003] However, the existing side wall design needs to maintain a certain wall width to ensure that the gas will not be excessively diffused due to too fast flow rate, affecting the ignition effect, which often leads to the size of the side wall being too large, and the increase of wall width makes the electric arc generated by the ignition needle more likely to contact the gas mixture of sufficient concentration, although it improves the ignition reliability to some extent, but at the same time, it also causes a series of new problems.

[0004] In related technologies, the increased size of the side wall easily hinders the smooth contact of secondary air, and insufficient secondary air supply may lead to incomplete combustion, which not only reduces the combustion efficiency, but also may produce harmful gas emissions, affecting environmental quality and equipment performance.

[0037] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

In addition, the features defined as "first" and "second" can be explicitly or implicitly included one or more features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0039] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] In the related art, the increased side wall size easily hinders the smooth contact of the secondary air, and the insufficient supply of secondary air can cause incomplete combustion, not only reducing the combustion efficiency, but also possibly producing harmful gas emissions, affecting the environmental quality and equipment performance. In addition, the excessive side wall can also cause the phenomenon of local non-combustion of the flame, further aggravating the combustion instability and safety hazards.

[0041] Reference is made below to Figures 1-4 The burner assembly 10 according to the embodiments of the present application is described.

[0042] As Figures 1-3 shown, the burner assembly 10 according to the present application is used in a cooking device 1, and the burner assembly 10 includes a burner 101 provided with a fire hole 1011 adapted to flow through gas, the fire hole 1011 being used to flow through gas to generate a flame.

[0043] The burner assembly 10 further comprises a pilot plate 103 arranged at a side of the burner 101, and the pilot plate 103 extends in a direction away from the fire hole 1011. When the gas flows out of the fire hole 1011, it will naturally flow along the direction in which the pilot plate 103 extends. An end of the pilot plate 103 is formed with a flow resistance portion 1031 which is at least partially opposite to the fire hole 1011 in the gas flow direction. When the gas flows to the flow resistance portion 1031, it will be hindered, and the Coanda effect is generated. That is, when the gas encounters the protruding flow resistance portion 1031, it will tend to adhere to the surface of the flow resistance portion 1031 and flow along it, so that the speed of the gas flowing in the direction in which the pilot plate 103 extends is slowed down, the ignition flame is kept in place, and the ignition performance is improved.

[0044] By arranging the flow resistance portion 1031 at the end of the pilot plate 103, the wall width of the pilot plate 103 is reduced, so that the combustion process is optimized and the overall performance is improved. The presence of the flow resistance portion 1031 can make up for the problem of weakened resistance reduction effect due to the reduced wall width of the pilot plate 103. Although the increased side wall size may hinder the smooth contact of the secondary air, the arrangement of the flow resistance portion 1031 effectively improves the combustion process by optimizing the gas flow path and speed and enhancing the stability of the electric arc, so that the secondary air can more fully participate in the combustion, thereby avoiding the problems of insufficient combustion and harmful gas emission.

[0045] Therefore, according to the burner assembly 10 of the utility model, the flow resistance portion 1031 at the end of the pilot plate 103 optimizes the gas flow path and the ignition performance, realizes an efficient and stable combustion process, reduces harmful gas emission, and improves the overall performance.

[0046] According to some embodiments of the utility model, as shown in Figure 4 The burner assembly further comprises an electrode 102 arranged at one side of the burner 101, and the electrode 102 is provided with a discharge end 1021 which is arranged in a spaced manner with the fire hole 1011 to ensure that an electric arc can be generated during ignition, so that the gas is ignited. The flow resistance portion 1031 is adapted to form an electric arc with the discharge end 1021. When the discharge end 1021 releases an electric arc, a stable electric arc can be formed between the flow resistance portion 1031 and the discharge end 1021. The high temperature of the electric arc can quickly ignite the decelerated gas, thereby starting the combustion process and generating a flame. Due to the Coanda effect, the ignited flame will be stably kept near the flow resistance portion 1031, rather than being blown away by the high-speed flowing gas.

[0047] According to some embodiments of the utility model, as shown in Figure 4As shown, the fire board 103 and the electrode 102 are arranged on both sides of the burner 101 in the width direction, which helps the electrode 102 to effectively interact with the flow resistance part 1031 at the end of the fire board 103 to generate an arc during ignition, thereby completing the ignition process and realizing the ignition of the gas between the electrode 102 and the fire board 103.

[0048] According to some embodiments of the present application, as shown in Figures 1-3 As shown, the fire board 103 includes a fixed support 1032 and a flow guide part 1033. The fixed support 1032 is used to stably mount the fire board 103 on the burner 101. The fixed support 1032 is fixedly connected with the burner 101, thereby ensuring that the fire board 103 will not fall off or shift during use, and ensuring the reliability of ignition. The flow guide part 1033 is connected with the fixed support 1032 and at least partially attached to the side wall of the burner 101, which helps to enhance the stability of the fire board 103 and enables it to more effectively guide the flow of gas. The flow guide part 1033 protrudes from the side of the burner 101 where the fire hole 1011 is arranged in the direction of gas flow, so that when the gas flows out of the fire hole 1011, it will first encounter the flow guide part 1033 and flow according to the shape and direction of the flow guide part 1033. The free end of the flow guide part 1033 is formed with a flow resistance part 1031, so that the gas flowing out of the fire hole 1011 is hindered when flowing along the flow guide part 1033 to the flow resistance part 1031, thereby triggering the Coanda effect and slowing down the flow of gas, which is conducive to ignition and flame stability.

[0049] According to some embodiments of the present application, as shown in Figure 1 and Figure 2 As shown, the end face of the burner 101 is formed with a fire hole 1011. The fire hole 1011 is a passage for the gas to flow out and generate a flame, and the gas can uniformly and stably flow out of the fire hole 1011 and form a flame under the action of an arc. The flow guide part 1033 is configured as a flow guide plate orthogonal to the end face. The flow guide plate is used to guide and regulate the flow of gas. By the flow guide plate, the flow direction and speed of the gas can be optimized before it flows out of the fire hole 1011, thereby further improving the combustion efficiency. The surface of the flow guide plate is formed with a flow guide surface orthogonal to the end face, so that the gas flowing out of the end face of the burner 101 can flow under the guidance of the flow guide surface. The flow guide surface further regulates the flow of gas through interaction with the gas to ensure that the gas can achieve the best flow state when flowing out of the fire hole 1011, thereby realizing more sufficient and efficient combustion.

[0050] According to some embodiments of the present application, as shown in Figures 1-3As shown, the burner 101 comprises a base 1012 and a flow-through shell 1013. The base 1012 is used to carry the flow-through shell 1013 and provides a mounting base for the flow-through shell 1013. The flow-through shell 1013 is arranged on the base 1012, and the inside of the flow-through shell 1013 is formed with a channel suitable for the flow of fuel gas, for the flow of fuel gas. The end of the flow-through shell 1013 is formed with a fire hole 1011, so that the fuel gas flowing in the flow-through shell 1013 can flow out of the fire hole 1011 and ignite to form a flame.

[0051] The flow-through shell 1013 is configured to be spaced apart in the length direction of the base 1012, and after the fuel gas flowing out of one flow-through shell 1013 is ignited, the flame will continue to burn along the arrangement direction of the flow-through shell 1013. Since the flow-through shells 1013 are spaced apart, each flow-through shell 1013 will independently generate a flame. The adjacent two flow-through shells 1013 are formed with a connecting plate 1014, so that the plurality of flow-through shells 1013 form an integral whole, enhancing the structural strength. The connecting plate 1014 also provides a position for the burner 101 to connect with the fixed support 1032. Through the connection of the connecting plate 1014 and the fixed support 1032, the relative position of the burner 101 and the ignition plate 103 can be fixed, so that the fuel gas can be reliably ignited. The flow-blocking portion 1031 is opposite to the end of the flow-through shell 1013 and is spaced apart in the height direction, so that the flow-blocking portion 1031 is aligned with the end of the flow-through shell 1013 in the height direction, and the fuel gas flowing out of the fire hole 1011 at the end of the flow-through shell 1013 flows towards the flow-blocking portion 1031. There is a spacing distance between the flow-blocking portion 1031 and the end of the flow-through shell 1013, so that the flow-guiding portion 1033 guides the flow of fuel gas between the flow-blocking portion 1031 and the end of the flow-through shell 1013. After being guided by the flow-guiding portion 1033, the fuel gas flowing out of the fire hole 1011 at the end of the flow-through shell 1013 flows to the flow-blocking portion 1031, so that the fuel gas and oxygen are mixed sufficiently to optimize the flow and combustion process of the fuel gas, thereby generating a stable flame.

[0052] According to some embodiments of the present application, as shown in Figure 4 As shown, the electrode 102 and the ignition plate 103 are arranged on both sides of the flow-through shell 1013 in the width direction, so that the ignition plate 103 can accurately receive the ignition spark from the electrode 102. During the ignition process, the spark generated by the electrode 102 can cross the width of the flow-through shell 1013 and directly act on the ignition plate 103, thereby effectively igniting the fuel gas flowing out of the fire hole 1011 of the flow-through shell 1013.

[0053] According to some embodiments of the present application, the fixed support 1032 is formed with a bending section, which protrudes away from the edge of the connecting plate 1014, so as to form an effective lap joint with the edge of the connecting plate 1014. The bending section forms a limiting groove for lapping with the bending section. During assembly, the edge of the connecting plate 1014 can be firmly embedded in the limiting groove, ensuring a tight fit between the two, effectively preventing loosening or falling off due to vibration or external force. When installing the ignition plate 103 to the burner 101, the limiting groove can guide the connecting plate 1014 to accurately align and insert, simplifying the installation process and improving work efficiency.

[0054] According to some embodiments of the present application, as shown in Figure 1 and Figure 2 , a plurality of flow guide ribs 1013a are arranged in the flow-through housing 1013. The gas in the flow-through housing 1013 flows between two adjacent flow guide ribs 1013a, not only optimizing the flow path of the gas, but also significantly improving the performance of the burner 101. By arranging a plurality of flow guide ribs 1013a spaced from each other, the flow of gas is guided and constrained by the flow guide ribs 1013a, and the flow of gas becomes more orderly and controllable, which helps to form a more stable and uniform flame, improving the combustion efficiency and thermal efficiency of the burner 101.

[0055] According to some embodiments of the present application, as shown in Figure 1 and Figure 2 , each flow-through housing 1013 is configured as a polygonal prism. The polygonal prism is composed of a polygonal base and a plurality of side surfaces connecting the polygonal base. The side surface can be triangular, quadrilateral, pentagonal, etc., depending on the number of edges of the prism. The shape of the polygonal prism allows the flow-through housing 1013 to better disperse stress when subjected to external forces, thereby improving its overall structural strength. And the gas flowing out of the fire hole 1011 of the flow-through housing 1013 in the shape of a polygonal prism is uniformly distributed around the center of the polygonal prism. By the polygonal prism shape, the gas flowing out of the fire hole 1011 of the flow-through housing 1013 can form a more stable and uniform flame.

[0056] According to some embodiments of the present application, as shown in Figure 4As shown, the distance between the flow blocking part 1031 and the fire hole 1011 is D1, and satisfies: 0mm < D1≤10mm. D1 greater than 0mm means that the flow blocking part 1031 and the fire hole 1011 must maintain a certain distance to avoid the flow blocking part 1031 directly blocking the fire hole 1011, so that the gas flowing out of the fire hole 1011 is fully mixed with oxygen and ignited near the flow blocking part 1031, improving the ignition performance. D1 less than or equal to 10mm ensures that the distance between the flow blocking part 1031 and the fire hole 1011 is not too large, so that the gas can smoothly reach the fire hole 1011 and be ignited. At the same time, the distance between the flow blocking part 1031 and the fire hole 1011 is also short enough, so that the flow blocking part 1031 can effectively regulate and control the gas flow, improve the stability of the flame. By limiting the distance D1 between the flow blocking part 1031 and the fire hole 1011, the stability and combustion efficiency of the flame can be improved while ensuring the ignition performance, which helps to realize a more efficient, stable and environmentally friendly combustion process.

[0057] According to some embodiments of the present application, as shown in Figure 4 As shown, the distance between the end of the flow blocking part 1031 and the discharge end 1021 is D2, and satisfies: 0mm < D2≤10mm. D2 greater than 0mm means that the end of the flow blocking part 1031 and the discharge end 1021 must maintain a certain distance to avoid the flow blocking part 1031 directly contacting the discharge end 1021, so that the end of the flow blocking part 1031 and the discharge end 1021 have sufficient space for gas flow, ensuring the ignition performance. D2 less than or equal to 10mm ensures that the distance between the end of the flow blocking part 1031 and the discharge end 1021 is not too large, so that the electric arc generated by the discharge end 1021 can effectively ignite the gas near the flow blocking part 1031. At the same time, the distance between the end of the flow blocking part 1031 and the discharge end 1021 is also short enough, so that the flow blocking part 1031 can play an effective regulating role in the ignition process, optimize the gas flow, and form an electric arc between the flow blocking part 1031 and the discharge end 1021, improve the stability and combustion efficiency of the flame. By limiting the distance D2 between the end of the flow blocking part 1031 and the discharge end 1021, the stability and combustion efficiency of the flame can be improved while ensuring the ignition performance, which helps to realize a more efficient, stable and reliable ignition process, thereby optimizing the overall performance of the burner 101.

[0058] According to some embodiments of the present application, as shown in Figure 4As shown, the distance between the end of the flow blocking part 1031 and the discharge end 1021 is D2, the distance between the discharge end 1021 and the fire hole 1011 is D3, and D3>D2 is satisfied. D3 being greater than D2 means that the arc generated by the discharge end 1021 first acts on the gas near the flow blocking part 1031 instead of directly acting on the fire hole 1011, so that the arc can be stably formed between the flow blocking part 1031 and the discharge end 1021, avoiding the arc being formed between the discharge end 1021 and the burner 101, which can cause damage to the burner 101, and helping to ensure that the gas has been sufficiently mixed with oxygen and ignited by the arc before reaching the flow blocking part 1031, thereby improving the stability of the flame and the combustion efficiency.
