Technical Field

[0001] This application relates to the field of kitchen appliances technology, and in particular to a burner and a stove. Background Technology

[0002] In related technologies, the gas in the burner flows through the flame holes and is ignited at the flame hole openings. However, insufficient air supply at the flame hole openings results in incomplete combustion of the gas, which is not environmentally friendly. Utility Model Content

[0003] This application provides a burner and a combustion stove to solve the problems of insufficient air supply at the burner opening and low gas combustion rate in related technologies.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a burner, the burner including a flame cap with a plurality of flame holes; a water pan fixing plate, the side of the water pan fixing plate near the flame holes being folded upward to form a flow guiding structure, the flow guiding structure and the flame holes forming a flow guiding channel, the flow guiding channel being used to guide air to the opening of the flame holes.

[0005] The beneficial effects of this application are as follows: In the burner provided by this application, the water pan fixing plate is folded upward on the side near the burner hole to form a flow guiding structure, and a flow guiding channel is formed between the flow guiding structure and the burner hole. The flow guiding channel of this application can guide air to the opening of the burner hole, increasing the air supply at the burner hole opening and making the gas combustion efficiency higher.

[0006] In some embodiments, there is a gap between the side surface of the flow guiding structure facing the fire hole and the outermost peripheral wall of the fire hole, and the gap value is between 0 mm and 5 mm.

[0007] In some embodiments, the flow guiding structure forms a first angle with the horizontal plane, and the axis of the fire hole in the depth direction forms a second angle with the horizontal plane. The first angle and the second angle are in the range of 0 to 90 degrees, and the first angle and the second angle may be the same or different in size.

[0008] In some embodiments, there is a gap between the side surface of the flow guiding structure facing the fire hole and the outermost peripheral wall of the fire hole, and the size of the gap gradually decreases from the root of the fire hole to the opening of the fire hole.

[0009] In some embodiments, the first included angle ranges from 30° to 60°.

[0010] In some embodiments, the flame cap is formed by a first plate and a second plate. The first plate has a plurality of outwardly protruding arc-shaped first hole walls. The first plate and the second plate are assembled to form the flame hole. There is a gap between the side surface of the flow guiding structure facing the flame hole and the outer surface of the first hole wall. A plurality of flow guiding channels are formed between the flow guiding structure and the outer surface of the flame hole. Two adjacent flow guiding channels are connected through the gap.

[0011] In some embodiments, the water tray fixing plate further includes a water tray body portion connected to the flow guiding structure. The first plate includes a first body portion and a first fire hole portion extending from the first body portion. The first hole wall is disposed in the first fire hole portion. The distance between the water tray body portion and the first body portion is greater than the distance between the flow guiding structure and the outermost peripheral wall of the fire hole.

[0012] In some embodiments, the water tray fixing plate is arranged in a ring around the fire hole, with an opening in the middle, and the projection of the fire hole on the radial plane is at least partially exposed from the opening.

[0013] In some embodiments, a combustion support is provided, which is fixedly connected to the flame cover and the water tray fixing plate; wherein the flame cover is installed above the combustion support, and the water tray fixing plate is installed above the flame cover.

[0014] In some embodiments, a center flame cap and a center ejector tube are both mounted on the combustion support; the combustion support also includes a mixing chamber that connects the center ejector tube to the center flame cap.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a burner and a combustion stove. A flow-guiding structure is formed by folding the water tray fixing plate upwards near the flame holes. This flow-guiding structure and the flame holes form a flow-guiding channel, which precisely guides air to the opening of the flame holes, increasing the air supply and thus improving the gas combustion rate. Therefore, this further enhances the combustion performance of the burner and achieves higher thermal efficiency in the combustion stove. The technical problem this application aims to solve is low gas combustion rate.

[0016] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a combustion stove, including a panel and a burner as described in any of the above embodiments, wherein the panel has an opening, the burner is installed at the opening, and the burner cap is exposed from the opening.

[0017] The beneficial effects of the combustion stove described in this application are the same as those of the aforementioned burner, and will not be repeated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] In related technologies, the gas in the burner flows through the flame holes and is ignited at the flame hole openings. However, insufficient air supply at the flame hole openings can easily lead to incomplete combustion of the gas. Furthermore, burners are mostly made of copper alloys, which have high manufacturing costs and high energy consumption in actual production, making them less environmentally friendly.

[0046] This application provides a burner 10, please refer to... Figures 1 to 3 , Figure 1 This is an axial sectional view of the burner provided in this application. Figure 2 This is an exploded structural diagram of the burner embodiment provided in this application. Figure 3 It is the burner in Figure 1 An enlarged view of one of the embodiments shown at point A.

[0047] The burner 10 includes a flame cap 110 and a water pan fixing plate 120. The flame cap 110 has multiple flame holes 111 to supply fuel gas to the burner 10. The water pan fixing plate 120 is positioned above the flame cap 110, and the side of the water pan fixing plate 120 near the flame holes 111 is folded upwards to form a flow guiding structure 121. A flow guiding channel 130 is formed between the flow guiding structure 121 and the flame holes 111. Figure 3 As indicated by the black arrow, the flow channel 130 is used to precisely guide air to the opening of the burner hole 111 to improve the supply of secondary air, thereby improving the combustion efficiency of the burner.

[0048] like Figure 6 and Figure 7 As shown, Figure 6 This is an exploded structural diagram of the burner cap of the burner in this application. Figure 7This is a partially enlarged view of an embodiment of the first plate of the burner cap of the burner of this application. A gap exists between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outermost peripheral wall of the flame hole 111, with the gap value ranging from 0 mm to 5 mm. The outermost peripheral wall refers to the flame hole 111 being formed by the enclosure of the first plate 112 and the second plate 113. The first plate 112 has multiple outwardly protruding arc-shaped first hole walls 1121, and the second plate 113 has multiple arc-shaped second hole walls 1131 protruding to the opposite side. The first hole walls 1121 and the second hole walls 1131 are assembled to form the flame hole 111. The line segment formed by the set of points at the outermost arc of the first hole wall 1121 is the outermost peripheral wall; that is, the line segment of the first hole wall 1121 from the opening of the flame hole 111 to the outermost part of the root of the flame hole 111 is the outermost peripheral wall. In this embodiment, the flame cap 110 can be an outer ring flame cap; in some other embodiments, the flame cap 110 can also be an inner ring flame cap, and there is no limitation here.

[0049] In one embodiment, see Figure 8 , Figure 8 This is a partially enlarged view of another embodiment of the first plate of the burner cap of the present application. The burner cap 110 includes a first plate 112, a partition plate 115, and a second plate 113. The partition plate 115 is disposed between the first plate 112 and the second plate 113 to separate the first plate 112 and the second plate 113. The flame hole 111 is formed by the first plate 112 and the second plate 113. The first plate 112 has a plurality of outwardly protruding prismatic first hole walls 1121, and the second plate 113 has a plurality of prismatic second hole walls 1131 protruding to the opposite side. The first hole walls 1121 and the second hole walls 1131 are assembled to form the flame hole 111. The outermost prismatic side of the first hole wall 1121 is the outermost peripheral wall, that is, the outermost side of the first hole wall 1121 along the depth direction of the flame hole is the outermost peripheral wall. There is a gap between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outermost peripheral wall of the flame hole 111. The gap value is between 0mm and 5mm. Through the design of the above structure, the flow guiding structure 121 and the flame hole 111 are kept at a suitable distance to improve the air supply effect and improve the combustion efficiency of the burner 10.

[0050] In one embodiment, there is a gap between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outermost peripheral wall of the flame hole 111, with the gap value being 2mm to 3mm, so as to make the structure of the burner 10 more compact.

[0051] Furthermore, the shape of the first hole wall 1121 of the fire hole 111 can be various. The shape of the first hole wall 1121 does not affect its function. It is understood that in other embodiments, the first hole wall 1121 can also be other shapes, which are not limited here.

[0052] See Figure 9 , Figure 9This is an enlarged view of one embodiment of the water pan fixing plate and burner cap of the burner of this application. The water pan fixing plate 120 is folded upward on the side near the burner hole 111 to form a flow guiding structure 121. The flow guiding structure forms a first angle α with the horizontal direction, and the depth direction x (also the length direction) of the burner hole 111 forms a second angle b with the horizontal direction. The range of α and b is 0 to 90°. The flow guiding structure 121 and the burner hole 111 converge towards the interior of the burner 10 to guide the air directly into the area inside the burner 10, preventing the air from diffusing to the surrounding area of ​​the burner 10, thereby ensuring the flow guiding effect of the flow guiding structure 121. The first angle α and the second angle b can be the same or different, and the direction of the flow guiding structure 121 can be the same or different from the depth direction x of the burner hole 111.

[0053] Furthermore, the water tray fixing plate 120 folds upward on the side near the flame hole 111 to form a flow guiding structure 121. The first angle α formed by the flow guiding structure and the horizontal direction is an acute angle, ranging from 30° to 60°. This causes the flow guiding structure 121 to tilt inward into a frustum shape, directly guiding air into the area inside the flame cap 110 and preventing air from diffusing to the surrounding area of ​​the flame cap 110. In this embodiment, the flame hole 111 is tilted, and the second angle b formed by the depth direction x (also the length direction) of the flame hole 111 and the horizontal direction is an acute angle, ranging from 30° to 60°, thereby ensuring the flame concentrating effect of the flame cap 110. The first angle α and the second angle b can be the same or different.

[0054] It is understandable that when the angle α between the guide structure 121 of the water tray fixing plate 120 and the horizontal direction exceeds the range of 0 to 90°, the air between the water tray fixing plate 120 and the flame cover 110 is difficult to be introduced into the area inside the flame cover 110, causing the air to diffuse around the flame cover 110, which impairs the air replenishment effect.

[0055] In one embodiment, 'a' can be 0°, 30°, 40°, 50°, 60°, or any other value between 30° and 60°.

[0056] See Figure 3 A gap exists between the side surface of the flow guiding structure 121 facing the burner hole 111 and the outermost peripheral wall 114 of the burner hole 111. The size of the gap is uniform and constant from the root of the burner hole 111 to its opening. That is, the distance between the flow guiding structure 121 and the burner hole 111 located on the same side within the same axial section and along the outermost peripheral wall 114 of the first hole wall 1121 remains constant. This distance is less than or equal to 5 mm. The size of the flow guiding channel 130 between the flow guiding structure 121 and the burner hole 111 remains constant, so that air can be directly delivered to the opening of the burner hole 111 through the flow guiding channel 130 between the flow guiding structure 121 and the burner hole 111, which facilitates the mixing of air and fuel gas.

[0057] See Figure 4 , Figure 4 It is the burner in Figure 1 In the enlarged view of another embodiment shown at point A, there is a gap between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outermost peripheral wall 114 of the flame hole 111. The size of the gap gradually decreases from the root of the flame hole 111 to the opening of the flame hole 111. That is, within the same axial section, the distance between the flow guiding structure 121 and the outermost peripheral wall 114 of the flame hole 111 on the same side gradually decreases from the root of the flame hole 111 to the opening of the flame hole 111. The flow guiding channel 130 between the flow guiding structure 121 and the flame hole 111 gradually narrows from the root of the flame hole 111 to the opening of the flame hole 111, forming a converging state. This allows air to slow down when passing through the gradually narrowing flow guiding channel 130, facilitating the rapid replenishment of air at the opening of the flame hole 111.

[0058] See also Figure 4 The distance between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outermost peripheral wall 114 of the flame hole 111 gradually decreases along the opening direction of the flame hole. The maximum distance between the flow guiding structure 121 and the outermost peripheral wall 114 of the flame hole 111 at the root of the flame hole is less than or equal to 5 mm, so that the distance between the flow guiding structure 121 and the flame hole 111 is appropriate and facilitates the flow of air.

[0059] See Figure 3 The gap between the flow guiding structure 121 and the two adjacent first hole walls 1121 forms a flow guiding channel 130. Multiple flow guiding channels 130 are formed between the flow guiding structure 121 and the outer surface of the fire hole 111. When the minimum gap between the side surface of the flow guiding structure 121 facing the fire hole 111 and the outermost peripheral wall 114 of the fire hole 111 is greater than 0 mm, two adjacent flow guiding channels 130 are connected to facilitate smooth airflow.

[0060] See Figure 3 There is a gap between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outermost peripheral wall 114 of the flame hole 111. The size of the gap is uniform and constant from the root of the flame hole 111 to the opening of the flame hole 111. When the gap is equal to 0 mm, multiple flow guiding channels 130 are formed between the flow guiding structure 121 and the outer surface of the flame hole 111. Two adjacent flow guiding channels 130 are not connected, and the structure of the flow guiding structure 121 is more compact.

[0061] See Figure 3 and Figure 4The flame cap 110 is formed by a first plate 112 and a second plate 113. The first plate 112 has multiple outwardly protruding arc-shaped first hole walls 1121, and the second plate 113 has multiple arc-shaped second hole walls 1131 protruding to the opposite side. The flame hole 111 is formed by assembling the first plate 112 with the arc-shaped first hole walls 1121 and the arc-shaped second hole walls 1131 of the second plate 113. A gap exists between the side surface of the flow guiding structure 121 facing the flame hole 111 and the outer surface of the first hole wall 1121. Multiple flow guiding channels 130 are formed between the flow guiding structure 121 and the outer surface of the flame hole 111, and two adjacent flow guiding channels 130 are connected by the gap. In other embodiments, the second plate 113 may also be a smooth curved surface, and the flame hole 111 is formed by assembling the first plate 112 with the arc-shaped first hole walls 1121 and the second plate 113. The shape of the second plate 113 is not limited here.

[0062] like Figures 3 to 5 As shown, Figure 5 This is an axial sectional view of an embodiment of the burner's water pan fixing plate of this application. The water pan fixing plate 120 also includes a water pan body portion 122 connected to the flow guiding structure 121. The water pan body portion 122 is disposed around and connected to the flow guiding structure 121. The first plate 112 includes a first body portion 1122 and a first flame hole portion 1123 extending from the first body portion 1122. The first hole wall 1121 is disposed on the first flame hole portion 1123, and the first flame hole portion 1123 protrudes outward to form a plurality of first hole walls. 1121, the water pan body 122 and the first body 1122 form an air intake gap, and the flow guiding structure 121 and the flame hole 111 form a flow guiding channel 130. The air intake gap and the flow guiding channel 130 are connected. When the burner 10 is ignited, the opening of the flame hole 111 has a high temperature and low air pressure due to the flame. Under the action of the air pressure difference, the external air first flows through the air intake gap, and then through the flow guiding channel 130 to reach the opening of the flame hole 111, realizing precise air guidance, improving the air replenishment effect, and thus improving the combustion efficiency.

[0063] like Figure 3 and Figure 4 As shown, the distance between the water pan body 122 and the first body 1122 is greater than the distance between the flow guiding structure 121 and the outermost peripheral wall 114 of the flame hole 111. When the burner 10 is ignited, the external air first flows through the air intake gap under the action of the air pressure difference, and then the flow velocity increases when it passes through the slightly narrower flow guiding channel 130, and finally it is guided to the opening of the flame hole 111 to achieve precise and rapid air replenishment.

[0064] See Figures 10 to 12 , Figure 10 This is an enlarged view of a second embodiment of the matching of the water tray fixing plate and the burner cap of the burner in this application. Figure 11 This is an enlarged view of a third embodiment of the matching of the water tray fixing plate and the burner cap of the burner in this application. Figure 12 This is an enlarged view of the fourth embodiment of the cooperation between the water pan fixing plate and the burner cap of the burner in this application.

[0065] The water tray fixing plate 120 is arranged in a ring around the flame hole 111. An opening is provided in the middle of the water tray fixing plate 120. At least part of the projection of the flame hole 111 on the radial plane is exposed through the opening, so as to avoid the water tray fixing plate 120 from blocking the flame hole 111 and causing the flame to directly contact the water tray fixing plate 120, which would damage the service life of the water tray fixing plate 120.

[0066] In one implementation, see Figure 10 A partial enlarged view of the axial section of the burner 10 along its central axis, with the radial direction perpendicular to the axial direction. The edge of the flow guiding structure 121 near the middle opening of the water pan fixing plate 120 is coplanar with the edge of the first flame hole 1123 near the flame hole 111 in the axial direction. The projection of the edge of the flow guiding structure 121 near the middle opening of the water pan fixing plate 120 on the radial plane is outside the projection of the edge of the first flame hole 1123 near the flame hole 111 on the radial plane, so that the opening of the flame hole 111 is exposed from the middle opening of the water pan fixing plate 120, and the flame at the opening of the flame hole 111 will not touch the water pan fixing plate 120, thus extending the service life of the water pan fixing plate 120.

[0067] In one implementation, see Figure 11 The image shows a partially enlarged view of a cross-section along the central axis of another embodiment of the burner 10. The radial direction is perpendicular to the axial direction. In the axial direction, the edge of the guide structure 121 near the central opening of the water pan fixing plate 120 is located below the edge of the first flame hole portion 1123 near the flame hole 111. This ensures that the edge of the water pan fixing plate 120 near the central opening is lower than the edge of the first flame hole portion 1123 near the flame hole 111, preventing the flame from scorching the guide structure 121 of the water pan fixing plate 120. The projection of the edge of the guide structure 121 near the central opening of the water pan fixing plate 120 onto the radial plane is outside the projection of the edge of the first flame hole portion 1123 near the flame hole 111 onto the radial plane. This ensures that the opening of the flame hole 111 protrudes from the central opening of the water pan fixing plate 120, preventing the flame at the opening of the flame hole 111 from touching the water pan fixing plate 120 and extending the service life of the water pan fixing plate 120.

[0068] In one implementation, see Figure 12The image shows a partial enlarged view of a cross-section along the central axis of another embodiment of the burner 10, with the radial direction perpendicular to the axial direction. In the axial direction, the edge of the guide structure 121 near the middle opening of the water pan fixing plate 120 is located above the edge of the first flame hole portion 1123 near the flame hole 111, so that the guide structure 121 guides the air to the area inside the burner cap 110, preventing the air from diffusing to the area around the burner cap 110. The projection of the edge of the guide structure 121 near the middle opening of the water pan fixing plate 120 on the radial plane is outside the projection of the edge of the first flame hole portion 1123 near the flame hole 111 on the radial plane, so that the opening of the flame hole 111 is exposed from the middle opening of the water pan fixing plate 120, and the flame at the opening of the flame hole 111 will not touch the water pan fixing plate 120, thus extending the service life of the water pan fixing plate 120.

[0069] See Figure 2 The burner 10 also includes a combustion support 180, a flame cap 110 and a water tray fixing plate 120 fixed on the combustion support 180 to improve the stability of the burner 10; specifically, in one embodiment, the combustion support 180 may be set at the bottom of the burner 10, the flame cap 110 is installed above the combustion support 180, and the water tray fixing plate 120 is installed above the flame cap 110.

[0070] In one embodiment, the combustion bracket 180 includes a plurality of legs 182, and the water tray fixing plate 120 includes a plurality of pins 123 extending from the first body portion 1122. The legs 182 of the combustion bracket 180 can be used to fix and support the burner cap 110 and the pins 123 of the water tray fixing plate 120. The burner cap 110, the pins 123 of the water tray fixing plate 120 and the legs 182 of the combustion bracket 180 are fixed by screws to reinforce the burner 10. In other embodiments, the burner cap 110, the water tray fixing plate 120 and the combustion bracket 180 can also be fixedly connected by other means.

[0071] In one embodiment, the water tray fixing plate 120 is made of stainless steel sheet metal, which has low manufacturing cost, low energy consumption in actual production process, and is green and environmentally friendly.

[0072] See also Figure 2 The burner 10 also includes a central flame cap 140, which is fixed on the combustion support 180. In one embodiment, the flame cap 110 has an opening, and the central flame cap 140 is installed below the flame cap 110 and protrudes from the opening of the flame cap 110. It can be used to provide an inner ring flame to ensure that the flame cap 110 and the central flame cap 140 provide flame and inner ring flame respectively, and cooperate to ensure that the middle and edge of the pot bottom are heated evenly, so that the pot bottom is heated evenly as a whole, thereby ensuring the uniformity of the flame at the bottom of the pot.

[0073] See also Figure 2The burner 10 also includes a central ejector tube 150, and the combustion support 180 also includes a mixing chamber 181. The mixing chamber 181 is connected to the central ejector tube 150. The central ejector tube 150 is used to mix the gas and air evenly and then deliver them to the mixing chamber 181 of the combustion support 180. The mixing chamber 181 is connected to the central burner cap 140 to form a gas passage for the central burner cap 140.

[0074] The burner 10 also includes an air damper 160, which is used to adjust the size of the air inlet, thereby adjusting the size of the flame.
