Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a fire baffle and a pellet oven. Background Technology

[0002] A pellet oven is a device that uses pellet fuel to bake food. The pellet fuel used is mostly biomass pellet fuel made from materials such as sawdust and straw. This material produces fewer pollutants when burned, making it more environmentally friendly than traditional fuels such as coal. It also heats up quickly and has high heating efficiency.

[0003] Pellet ovens typically use a feeding mechanism to deliver pellet fuel into the burner within the oven cavity. The burner is open at the top, and the flame directly heats the drip tray below the grill. The heat is then transferred to the grill through the drip tray's heat absorption. Because the flame produced by the burner rises directly upwards, its energy radiates directly upwards, creating a localized high-intensity heat flow field directly above the burner. The temperature rise rate in this area is significantly higher than in other areas, and the temperature value is noticeably higher. This results in uneven heat distribution within the grill's plane, affecting the uniformity of food heating. Utility Model Content

[0004] The first technical problem solved by this utility model is to provide a heat shield that can effectively improve the uniformity of heat distribution within the plane of the grill.

[0005] The second technical problem solved by this invention is to provide a pellet oven that can effectively ensure the uniformity of heat distribution within the grill plane.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] In one aspect, a fire baffle is provided for use with a pellet furnace burner. The fire baffle is positioned above the burner, and an ignition part is provided at a position directly opposite the burner. Fire holes are provided on the outer periphery of the ignition part to guide the flame to the outer periphery of the ignition part, so that the heat can be evenly distributed inside the furnace.

[0008] The fire baffle plate of this utility model has the following beneficial effects compared with the prior art:

[0009] The aforementioned baffle plate guides the flame initially through the ignition section directly opposite the burner. It also diverts the concentrated flame into multiple diffused flames that flow out through the flame holes around the ignition section. This disperses the high-intensity heat flow above the burner to the area around the ignition section, preventing localized high-temperature zones directly above the burner caused by direct flame. This reduces the rate of localized heating in the area directly above the burner. After the flame diffuses through the flame holes, it covers a larger cross-section of the oven cavity, allowing the oil collection tray below the grill to receive heat more extensively, reducing the difference in heat received by different areas, and improving the uniformity of heat distribution within the grill plane.

[0010] In one embodiment, the fire baffle includes a top wall, the area of ​​the top wall opposite to the burner being recessed toward the burner to form the ignition part, and the transition surface between the ignition part and the top wall is an inclined surface.

[0011] In one embodiment, the fire baffle includes a first sidewall and a second sidewall disposed opposite to each other, the first sidewall and the second sidewall being disposed on both sides of the top wall and connected to the top wall, the top wall, the first sidewall and the second sidewall forming a fire-gathering cavity.

[0012] In one embodiment, the fire baffle further includes a front wall, which is connected to the top wall, the first side wall and the second side wall. The ignition part is disposed at one end of the top wall near the front wall, and the side of the fire-gathering chamber opposite to the front wall has an open structure.

[0013] The fire hole includes a plurality of first fire holes and a plurality of second fire holes, wherein the first fire holes are disposed at the end of the top wall away from the front wall, and the second fire holes are disposed at the upper end of the front wall.

[0014] In one embodiment, the fire hole further includes a third fire hole, which is located at the upper end of the first sidewall or the second sidewall near the front wall.

[0015] In one embodiment, a first reinforcing portion is provided on the top wall, the first reinforcing portion is disposed between each of the first fire holes, and the first reinforcing portion is recessed from the top wall into the interior of the fire-gathering chamber.

[0016] In one embodiment, a second reinforcing portion is provided on the front wall, the second reinforcing portion being recessed from the front wall into the interior of the fire-gathering cavity.

[0017] In one embodiment, a third reinforcing portion is provided on both the first sidewall and the second sidewall. The third reinforcing portion is recessed into the interior of the fire-gathering cavity from the first sidewall and the second sidewall, and the bottom wall of the third reinforcing portion is provided with a reinforcing rib protruding outward from the fire-gathering cavity.

[0018] The second technical problem mentioned above is solved by the following technical solution:

[0019] A pellet furnace includes a baffle plate as described in any of the above embodiments.

[0020] The pellet furnace described in this utility model has the following advantages compared with the prior art:

[0021] The pellet furnace is equipped with a baffle plate, which guides the flame through the ignition part directly opposite the burner. The ignition part also diverts the concentrated flame into multiple diffused flames that flow out through the flame holes on the outer periphery of the ignition part. This disperses the high-intensity heat flow above the burner to the outer periphery of the ignition part, avoiding localized high-temperature zones formed directly above the burner due to direct flame. This reduces the local heating rate in the area directly above the burner. After the flame diffuses through the flame holes, it can cover a larger cross-section of the furnace cavity, allowing the oil receiving tray below the grill to receive heat more extensively, reducing the difference in heat received by different areas, and improving the uniformity of heat distribution within the grill plane.

[0022] In one embodiment, the bottom plate of the pellet furnace has a slot, the bottom of the front wall of the fire baffle has a tongue, the tongue is inserted into the slot, and the lower edge of the fire baffle abuts against the bottom plate of the furnace. Attached Figure Description

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0038] The feeder in a pellet mill is primarily designed inside the furnace body, connected and fixed to the feed hopper via the side plates. The burner needs to be positioned in the center of the furnace body so that during combustion, the heat can be evenly distributed to both sides of the furnace body via the top baffle, achieving a balanced internal temperature. This results in a relatively fixed internal structure for the pellet mill, limiting its flexibility. Both the burner and feeder must be located in the center of the furnace cavity to ensure uniform temperature distribution. When the burner and feeder are located elsewhere, uneven temperature distribution is likely to occur within the furnace. Figure 1 A schematic diagram of the structure of a fire baffle provided in an embodiment of the present invention is shown; Figure 2 This diagram shows a structural schematic of the open side of a fire baffle provided in an embodiment of the present invention; see reference. Figures 1 to 2To address the aforementioned problems, one embodiment of this utility model provides a fire baffle 100, which is disposed above a burner 200. A fire ignition part 111 is provided on the fire baffle 100 directly opposite the burner 200. Fire holes are provided on the outer periphery of the fire ignition part 111 to guide the flame to the outer periphery of the fire ignition part 111 so that the heat can be evenly distributed inside the furnace body.

[0039] The baffle plate 100 is positioned above the burner 200 to block the direct upward impact of the flames from the burner 200, preventing excessively high local temperatures. It also guides heat to diffuse outwards around the furnace. The size of the baffle plate 100 can be controlled by adjusting its size. The baffle plate 100 can be made of high-temperature resistant material, and its shape matches the internal space of the furnace. The burner 200 provides combustion space for the fuel, outputting flames and heat. The ignition section 111 can be integrally formed with the baffle plate 100, and it provides initial guidance for the flames emitted from the burner 200. The flame holes are located on the outer periphery of the ignition section 111, guiding the flame and heat from the ignition section 111 to various parts of the furnace body. This determines the range and uniformity of heat distribution. The position, shape, and size of the flame holes can be set according to actual needs, such as being annular or radial, so that heat can spread in all directions. After the flame is ejected through the flame holes, it can form multiple small flames, covering a larger area, avoiding the problem of overheating in the center of the furnace body while the temperature at the edges is low, and ensuring that the food inside the furnace can be heated evenly.

[0040] The aforementioned baffle plate 100 provides initial guidance to the flame through the ignition part 111 directly opposite the burner 200. The ignition part 111 also diverts the concentrated flame into multiple diffused flames that flow out through the fire holes around the ignition part 111. This disperses the high-intensity heat flow above the burner 200 to the area around the ignition part 111, avoiding a localized high-temperature zone directly above the burner 200 caused by direct flame. This reduces the localized heating rate in the area directly above the burner 200. After the flame diffuses through the fire holes, it can cover a larger cross-section of the oven cavity, allowing the oil receiving tray below the grill to receive heat over a wider area, reducing the difference in heat received by different areas, and improving the uniformity of heat distribution within the grill plane.

[0041] In one embodiment, the fire baffle 100 includes a top wall 110. The area of ​​the top wall 110 opposite to the burner 200 is recessed towards the burner 200 to form the ignition part 111. The transition surface between the ignition part 111 and the top wall 110 is a slope. The top wall 110 covers a certain area above the burner 200, and the core area opposite to the burner 200 is recessed towards the burner 200 to form the ignition part 111, which can block the direct flame from the burner 200. Its bottom surface can be as follows: Figure 1-4The circular transition surface refers to the slope that slopes from the edge of the ignition part 111 towards the plane of the top wall 110. The angle of inclination can be adjusted according to actual needs. Setting the transition surface as a slope allows the heat of the ignition part 111 to diffuse smoothly towards the top wall 110, avoiding heat accumulation caused by right angle or acute angle connection, and can guide the flame to flow towards the fire hole.

[0042] In one embodiment, the fire baffle 100 includes a first sidewall 120 and a second sidewall 130 disposed opposite to each other. The first sidewall 120 and the second sidewall 130 are disposed on both sides of the top wall 110 and connected to the top wall 110. The top wall 110, the first sidewall 120, and the second sidewall 130 enclose a fire-concentrating cavity 150. Figure 2 As shown, the top wall 110, the first side wall 120, and the second side wall 130 form a fire-concentrating cavity 150, which can effectively constrain the spread of the flame, reduce the irregular flow of the flame to the surroundings, and promote the efficient conversion of flame energy into effective heat.

[0043] In one embodiment, the fire baffle 100 further includes a front wall 140, which is connected to the top wall 110, the first side wall 120, and the second side wall 130. The ignition part 111 is disposed at one end of the top wall 110 near the front wall 140. The fire-gathering chamber 150 has an open structure on the side opposite to the front wall 140. The fire holes include a plurality of first fire holes 112 and a plurality of second fire holes 141, wherein the first fire holes 112 are disposed at one end of the top wall 110 away from the front wall 140, and the second fire holes 141 are disposed at the upper end of the front wall 140. The front wall 140 prevents the random spread of flames towards the front end. The first flame hole 112 is located at the end of the top wall 110 away from the front wall 140. The side of the flame-gathering chamber 150 opposite to the front wall 140 (i.e., the rear side of the flame-gathering chamber 150) is open, which facilitates the transfer of heat to the rear side of the flame-gathering chamber 150, allowing the oil receiving tray to fully absorb heat. In some embodiments, to save costs, the feeder size is shortened. In this case, the burner 200 is closer to one end of the furnace body (the end closer to the front wall 140), while the other end of the furnace body is farther from the burner 200. The first flame hole 112 and the open structure help ensure that the area in the furnace far from the burner 200 can fully absorb heat even with a shortened feeder. To allow the oil receiving tray to absorb heat more fully, the area of ​​the first flame hole 112 can be larger than the area of ​​the second flame hole 141.

[0044] In one embodiment, the flame hole further includes a third flame hole 121, which is located at the upper end of the first sidewall 120 or the second sidewall 130 near the front wall 140. The front wall 140 of the baffle plate 100 is typically closer to the furnace lid. Opening the furnace lid accelerates heat loss. To ensure that this area is also adequately heated, the third flame hole 121 is located at the upper end of the first sidewall 120 or the second sidewall 130 near the front wall 140, guiding the flame towards the area near the furnace lid and resulting in a more thorough heat distribution within the furnace.

[0045] In one embodiment, a first reinforcing portion 113 is provided on the top wall 110. The first reinforcing portion 113 is disposed between each of the first flame holes 112, and the first reinforcing portion 113 is recessed from the top wall 110 into the interior of the flame-gathering chamber 150. The flame holes weaken the overall rigidity of the top wall 110. By placing the first reinforcing portion 113 between each of the first flame holes 112, the recessed first reinforcing portion 113 can disperse the thermal stress and external pressure on the top wall 110 at high temperatures by changing the material's stress distribution, reducing deformation or cracking caused by frequent heating and cooling. It also plays a minor guiding role, further optimizing the heat distribution within the furnace.

[0046] In one embodiment, a second reinforcing part 142 is provided on the front wall 140, and the second reinforcing part 142 is recessed from the front wall 140 into the interior of the fire-gathering cavity 150.

[0047] In one embodiment, a third reinforcing portion 122 is provided on both the first sidewall 120 and the second sidewall 130. The third reinforcing portion 122 is recessed into the fire-gathering cavity 150 from the first sidewall 120 and the second sidewall 130, and a reinforcing rib 123 protruding outward from the fire-gathering cavity 150 is provided on the bottom wall of the third reinforcing portion 122. Similarly, the second reinforcing portion 142 and the third reinforcing portion 122 also optimize the stress distribution of the fire baffle 100 through the recessed structure. The reinforcing rib 123 provided on the bottom wall of the third reinforcing portion 122 can further strengthen the sidewall and reduce the deformation of the fire baffle 100 during long-term use.

[0048] A pellet furnace 10 includes a baffle plate 100 as described in any of the above embodiments.

[0049] The beneficial effects of the pellet furnace 10 of this utility model compared with the prior art are as follows:

[0050] The pellet furnace 10 is equipped with a baffle plate 100, which guides the flame initially through the ignition part 111 facing the burner 200. The ignition part 111 also diverts the concentrated flame into multiple diffused flames that flow out through the fire holes around the ignition part 111. This disperses the high-intensity heat flow above the burner 200 to the area around the ignition part 111, avoiding the formation of a local high-temperature zone directly above the burner 200 due to direct flame. This reduces the local heating rate in the area directly above the burner 200. After the flame diffuses through the fire holes, it can cover a larger cross-section of the furnace cavity, allowing the oil receiving tray under the grill to be heated more extensively, reducing the difference in heat received by different areas, and improving the uniformity of heat distribution within the grill plane.

[0051] In one embodiment, the furnace body bottom plate 300 of the pellet furnace 10 has a slot, and the bottom of the front wall 140 of the baffle plate 100 has a tongue 143, which is inserted into the slot, and the lower edge of the baffle plate 100 abuts against the furnace body bottom plate 300. Figure 1 , Figure 3 and Figure 5 As shown, the tongue 143 is a tongue-shaped structure formed at the bottom of the front wall 140. The tongue 143 is inserted into the slot of the furnace body bottom plate 300, and the lower edge of the baffle plate 100 abuts against the furnace body bottom plate 300, which can ensure the stable installation of the baffle plate 100 in the furnace. In some embodiments, the furnace body bottom plate 300 is a slope, and the lower edge of the baffle plate 100 is also a sloped structure, and the two have the same slope angle.

[0052] In one exemplary embodiment, a fire baffle 100 is provided, the structure of which is as follows: Figure 1-4As shown, the baffle plate 100 is box-shaped with four closed sides, a mounting surface at the bottom, and an open area at the rear for air circulation. Its outline is a parabolic jet shape. The baffle plate 100 has reinforcing ribs 123 on both sides to prevent deformation due to high temperatures during use. The top area, which is in direct contact with the flame, has a textured structure to guide the flame and heat flow while ensuring sufficient strength to minimize deformation under prolonged high-temperature operation. For installation, the tongue-like design at the front of the baffle plate 100 works with the furnace body's support to secure it firmly inside the furnace. In practical applications, when the feeder firebox of the pellet furnace 10 is burning, the flame jets within the firebox due to the internal fan's airflow. Upon contact with the baffle plate 100, the flame flows towards the open area. The design of the baffle plate 100 utilizes this principle to guide the heat distribution of the flame, thereby achieving a more even temperature distribution across the various baking surfaces within the furnace. To meet the design requirement of placing the feeder as close as possible to the left side of the furnace body, and to ensure that the temperature in all areas of the furnace reaches the same level when the fire pot burns in a non-central position, the design of the baffle plate 100 involved multiple tests. Ultimately, it was determined that three square slots with dimensions of 37.5*23mm were needed on the front and left (or right) sides. This design, using the baffle plate 100, ensures that the heat from the fire pot combustion is sufficient for heat transfer, keeping the furnace temperature at a uniform level. The two sloping trapezoidal slots at the top are also designed to follow the flame flow path. During flame jetting and combustion, some of the tail flame can escape through the trapezoidal openings, increasing the temperature in the middle of the furnace body. The trapezoidal opening dimensions are 60*19.5*91.8mm. This size effectively allows some of the flame tail flame to pass through, balancing the temperature at the back of the furnace body, while preventing all the flame from erupting at this point and causing localized high temperatures. The remaining flame heat is dissipated through the fully open area at the rear. The newly designed baffle plate 100 effectively distributes heat evenly from the edge area to the entire combustion plane inside the furnace, allowing the feeder to burn at the furnace edge. When designing pellet furnaces 10 of different sizes, the feeder assembly can simultaneously meet grilling requirements, saving design costs. It solves the design challenge of requiring the feeder of the pellet furnace 10 to burn in the center of the furnace. Utilizing airflow and fluid dynamics theories, the heat from the flame is further optimized and distributed to the grilling mesh through the new baffle plate 100, resolving the spatial design difficulties within the furnace. It reduces the design complexity of the feeder mechanism, allowing for compatibility with more furnace feeders, thus improving the adaptability of the pellet furnace 10.

[0053] In one exemplary embodiment, such as Figure 6As shown, a pellet furnace 10 is provided, including a baffle plate 100 as described in any of the above embodiments. The pellet furnace 10 may include components such as a furnace frame, fuel bin, furnace cavity, feeding mechanism, combustion canister, and baking tray. The combustion canister is used to burn pellet fuel, and the baffle plate 100 is disposed above the combustion canister. The ignition part 111 at least partially overlaps with the vertical projection of the combustion canister, thereby guiding the flame generated by the combustion canister and improving the uniformity of temperature distribution inside the furnace.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
