Description

Technical Field

[0001] The present invention relates to the technical field of oven accessories, and more specifically, to an oil-proof drip baking net, an oven, and a method for preparing the baking net. Background Art

[0002] Traditional baking nets use hollow metal grids as the bearing structure, exposing the food directly over the charcoal fire. Although this design can evenly heat the food, in a high-temperature environment, the grease of the meat will quickly melt and drip onto the charcoal fire, leading to a series of problems. First, when the grease drips onto the high-temperature charcoal fire, it will quickly vaporize and generate a large amount of smoke, which may contain harmful substances such as incompletely burned hydrocarbons and benzo[a]pyrene, posing a potential threat to human health. Second, the combustion of the grease may cause the flame to flash back, causing the local temperature of the food to rise suddenly, resulting in external charring or carbonization, while the inside may still not be fully cooked, affecting the taste and food safety. In addition, carcinogenic substances such as polycyclic aromatic hydrocarbons and heterocyclic amines may be produced on the charred food surface, further increasing the long-term health risks of consumption. Therefore, how to optimize the design of the baking net to reduce the direct dripping of grease and reduce the generation of smoke and harmful substances. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems in the related art to a certain extent. For this purpose, an embodiment of the present invention provides an oil-proof drip baking net. By providing through holes and an oil receiving groove on the oven, the through holes allow high-temperature air flow to pass through smoothly, thereby evenly heating the food. The grease dripping from the through holes is timely collected by the oil receiving groove below, effectively preventing the grease from directly dripping onto the heating source, reducing the smoke and harmful substances generated by high-temperature combustion, and thus significantly improving the hygiene and safety of the barbecue process.

[0004] An embodiment of the present invention also provides an oven having the above oil-proof drip baking net.

[0005] An embodiment of the present invention also provides a method for preparing an oil-proof drip baking net.

[0006] The technical solution adopted by the present invention is: to provide an oil-proof drip baking net, the baking net includes a wavy net surface, the highest point of each undulating area is a peak, and the lowest point is a valley. Through holes and an oil receiving groove are provided on the slope between the peak and the valley. The oil receiving groove is located below the through hole, and the vertical projection of the through hole partially or entirely lies within the upper opening area of the oil receiving groove to guide the oil droplets into the oil receiving groove.

[0007] After adopting the above structure, part of the grease released by the food, under the action of high temperature, passes through the through holes and is guided into the oil receiving groove, thus avoiding directly dripping onto the charcoal fire, and the remaining part of the grease is drained to the bottom of the valley through the slope. This design effectively reduces the generation of smoke and harmful substances caused by the combustion of grease, and improves the hygiene and safety of the barbecue process.

[0008] Meanwhile, the provision of the through-holes ensures the smooth flow of the high-temperature air flow at the bottom of the grill net, enabling the food ingredients to still obtain sufficient charcoal heating effect, thus retaining the advantages of the traditional grill net. In addition, the undulating surface of the net increases the contact area between the food ingredients and the grill net, contributing to uniform heating, reducing adhesion, and improving the grilling effect. The slopes of some undulating areas can also prompt the grease to flow along a specific direction, thus avoiding problems such as local overheating or coking caused by grease accumulation. At the same time, compared with traditional grills, the internal components of the furnace body will not be contaminated by food residues or grease, improving the service life of the product.

[0009] According to an embodiment of the present invention, the slope between the peaks and valleys is an inclined surface, a concave arc surface or a convex arc surface; this enables the grease to flow along the slope under the action of gravity and converge into the through-holes and enter the oil receiving groove. Among them, the inclined surface structure can guide the grease to quickly flow towards the through-holes, reducing the residence time and lowering the generation of smoke and harmful substances due to high-temperature accumulation; the concave arc surface helps to collect the grease, preventing it from spreading to the surface of the grill net and further optimizing the oil drainage effect; the convex arc surface can increase the suspension degree of the food ingredients, reduce the direct contact area, lower the risk of adhesion, and enhance the convection of the hot air flow, thereby improving the baking uniformity.

[0010] According to an embodiment of the present invention, the oil receiving groove is formed by the partial concavity of the slope between the peaks and valleys; that is, the oil receiving groove is formed by a sheet metal stamping process. Specifically, the louver forming method is used, where one edge of the punch cuts the material to form the upper opening of the oil receiving groove, and the rest of the punch simultaneously stretches and deforms the material to form a undulating shape with one opening.

[0011] According to an embodiment of the present invention, the width b2 of the oil receiving groove is greater than the width b1 of the through-hole; due to the width b2 of the oil receiving groove being greater than the width b1 of the through-hole, under the action of the surface tension of the grease, the oil droplets are guided to the inside of the oil receiving groove at the edge of the through-hole and will not directly pass through the through-hole and drip onto the heat source below. In this way, the grill net can not only drain oil smoothly but also maintain the stability of charcoal heating, avoiding problems such as flame backflow or local overheating caused by grease combustion.

[0012] According to an embodiment of the present invention, a guiding portion is provided in the through-hole, and the guiding portion is used to guide the oil droplets to flow towards the oil receiving groove or the valley portion; the guiding portion can adopt an inclined or curved structure to ensure that the oil droplets will not disperse or flow in the reverse direction under the combined action of gravity and surface tension. Through this guiding action, the oil droplets are effectively guided to the oil receiving groove, thus preventing the grease from directly dripping onto the charcoal, reducing the generation of smoke and harmful substances, and at the same time improving the emission efficiency of the grease during the grilling process.

[0013] According to an embodiment of the present invention, the baking net is arranged obliquely from one end to the other end along the extending direction of the valley, so that the valley serves as a drainage groove to collect and drain the grease; during the flowing process of the grease, it naturally gathers in the valley part and is guided to the oil receiving groove or the oil drainage system below. The setting of the inclination angle can be optimized as needed, usually maintaining a certain slope, so that the grease can smoothly flow to the predetermined oil drainage area under the action of gravity.

[0014] According to an embodiment of the present invention, lapping edges are provided on one side or both sides of the baking net, and the two baking nets are stacked and connected to each other through their lapping edges, so as to form a larger and more stable baking surface. This design not only enhances the overall structural strength of the baking net, but also enables users to flexibly adjust the size and shape of the baking net according to needs, facilitating barbecue operations of different scales.

[0015] Connected by the lapping edges, the two baking nets can be firmly spliced together, avoiding problems of falling off or displacement during use. This stacked structure also makes the baking net easier to store and carry, because the occupied space can be reduced by stacking.

[0016] A roasting furnace includes the baking net described in any one of the above.

[0017] According to an embodiment of the present invention, the roasting furnace is provided with a detachable oil collecting container, and an oil collecting groove is arranged on the roasting furnace for receiving and guiding the oil droplets discharged from the baking net into the oil collecting container; the design of the oil collecting groove enables the grease to smoothly flow into the oil collecting groove after being discharged through the baking net, and the oil collecting groove itself plays a role in guiding the grease to flow towards the oil collecting container. The detachable design of the oil collecting container facilitates users to clean and maintain it after use. In this way, the grease will not stay inside the roasting furnace or drip onto the ground, reducing the pollution of the surrounding environment by oil stains and fumes.

[0018] A preparation method of an anti-dripping oil baking net as described in any one of the above includes the following steps: S1. Form through holes and an oil receiving groove on a metal sheet. S2. Form the undulating net surface on the metal sheet through a bending process. Description of the Drawings

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Embodiment 1

[0032] like Figures 1-6As shown, in this embodiment, an anti-drip oil baking net 10 is disclosed. The baking net 10 includes a wavy net surface. The highest point of each undulating area is a peak 11, and the lowest point is a valley 12. Through holes and oil receiving grooves are provided on the slope between the peak 11 and the valley 12. The oil receiving groove is located below the through hole, and the vertical projection of the through hole partially or entirely lies within the upper opening area of the oil receiving groove to guide oil droplets into the oil receiving groove.

[0033] Further, in this embodiment, the baking net 10 is integrally rectangular in shape, and its cross-section along the length direction presents a continuous wavy structure. In some embodiments, this wavy cross-section shows a regular wavy line, while in other embodiments, it presents an irregular wavy line. Among them, the wavy line can include the following several forms: 1. A sine wavy line distributed in the form of a standard sine curve; 2. A triangular wave wavy line composed of continuous isosceles triangles; 3. A sawtooth wave wavy line with one side sloping and the other side steep; 4. An irregular wavy line with irregular shape changes.

[0034] In this embodiment, the cross-section of the baking net 10 adopts a triangular wave wavy line design. The highest point of each triangular wave is the peak 11 (or called wave crest 11), and the lowest point is the valley 12 (or called wave trough 12). Since the peak 11 and the valley 12 extend along the length direction, the peak 11 forms a strip-shaped protrusion, and the valley 12 presents a long groove-shaped structure.

[0035] In addition, in this embodiment, the baking net 10 presents a straight tooth groove structure in the length direction, while in other embodiments, the length direction of the baking net 10 may be a wavy groove structure, that is, the valley 12 is distributed in a wavy line along the length direction.

[0036] In some other embodiments, the baking net 10 is integrally circular, triangular or polygonal.

[0037] Furthermore, in some embodiments, slopes are symmetrically provided on both sides of the triangular wave, and these slopes correspond to the two waistlines of the isosceles triangle. Among them, at least one slope is provided with through holes and oil receiving grooves, and in this embodiment, through holes and oil receiving grooves are provided on both slopes of the triangular wave. The through hole on one slope is called the first through hole 13, and the through hole on the other slope is called the second through hole 15; similarly, the oil receiving groove on one slope is called the first oil receiving groove 14, and the oil receiving groove on the other slope is called the second oil receiving groove 16.

[0038] Combined Figure 4As shown, the oven 20 in this embodiment is horizontally arranged as a whole, and the baking net 10 is slightly inclined in the length direction, that is, the baking net 10 is inclined from one end to the other along the extension direction of the valley 12, so that the valley 12 serves as a drainage groove to enable the grease to smoothly gather and drain. In Figure 4 , the black arrow indicates the main flow path of the high-temperature air flow, and the air flow passes through the first through hole 13 and the second through hole 15 from bottom to top, thereby effectively heating the food on the baking net 10. At the same time, the black teardrop symbol indicates the flow path of the oil droplets. In this embodiment, the vertical projection area a1 of the first through hole 13 is located within the upper opening area a2 of the first oil receiving groove 14, that is, a1 and a2 partially overlap, and the first through hole 13 is located obliquely above the first oil receiving groove 14. In this way, when the oil droplets generated after the food is heated, part of them directly flow along the slope to the valley 12 area, while the other part falls through the first through hole 13, and under the combined action of the surface tension and gravity of the oil droplets, they enter the first oil receiving groove 14 along the lower edge of the first through hole 13 and finally gather in the valley 12 area.

[0039] Furthermore, in this embodiment, the baking net 10 is made of a metal material and is formed by a sheet metal processing technology. The overall undulating shape of the baking net 10 is realized by a sheet metal bending process, while the first oil receiving groove 14 is prepared by a louver forming process, that is, one side edge of the punch is used to cut the material, and the rest of the punch is used to stretch and deform the material, thereby forming a undulating shape with one side open. Both the first oil receiving groove 14 and the second oil receiving groove 16 are recessed inwardly from the slope, and the cut openings are respectively located below the first through hole 13 and the second through hole 15.

[0040] Combined with Figure 5 As shown, in another embodiment, the vertical projection area a1 of the first through hole 13 is entirely located within the upper opening area a2 of the first oil receiving groove 14, and a2 completely covers a1, that is, the vertical projection of the through hole is entirely located within the upper opening area of the oil receiving groove, and the first through hole 13 is located obliquely above the first oil receiving groove 14. This structure further ensures that the oil droplets generated during the food heating process can smoothly flow into the oil receiving groove and finally gather in the valley 12 area, achieving a good anti-dripping effect.

[0041] Specifically, combined with Figure 6 As shown, in this embodiment, the slope between the peak 11 and the valley 12 presents as an inclined plane. In some other embodiments, the slope between the peak 11 and the valley 12 is an inwardly concave arc surface or an outwardly convex arc surface to optimize the flow path of the oil droplets and the oil drainage effect of the baking net 10. A guiding portion 13a is provided inside the through hole, and the guiding portion 13a is used to precisely guide the oil droplets to flow to the oil receiving groove or the valley 12 portion, improving the oil drainage efficiency.

[0042] Further, in this embodiment, the width b2 of the first oil receiving groove 14 in the length direction of the baking net 10 is greater than the width b1 of the first through hole 13 in the length direction of the baking net 10, so as to ensure sufficient oil collection space. Similarly, the width b2 of the second oil receiving groove 16 in the length direction of the baking net 10 is also greater than the width b1 of the second through hole 15 in the length direction of the baking net 10, to ensure the consistency and reliability of the oil drainage function.

[0043] Furthermore, in this embodiment, the overall shape of the first through hole 13 is trapezoidal in reverse, and the four corners are rounded to reduce the structural stress concentration caused by sharp corners and improve the durability of the baking net 10. Among them, the waistline part of the first through hole 13 serves as the guiding part 13a, which is specifically used to guide the oil droplets to flow smoothly to the slope between the first through hole 13 and the first oil receiving groove 14, thereby optimizing the flow path of the oil droplets. In other embodiments, the guiding part 13a can be directly used to guide the oil droplets to flow into the first oil receiving groove 14 to meet different usage requirements.

[0044] Specifically, as shown in Figure 3 the baking net 10 is provided with a lapping edge 17 on at least one side. Two baking nets 10 can be stacked up and down through their lapping edges 17 to form a larger and more stable baking surface to meet the cooking requirements of large-area food materials. In this embodiment, the lapping plate is designed with a V-shaped structure, and the lapping edge 17 of one baking net 10 can be stably stacked on the lapping edge 17 of another baking net 10, so as to effectively prevent the two baking nets 10 from separating during use and improve the overall stability and usage convenience.

[0045] As shown in Figures 8-10 in another embodiment, an oven 20 is disclosed, including the baking net 10 described in this embodiment.

[0046] Specifically, the oven 20 is equipped with a detachable oil collecting container 30 for easy cleaning and maintenance. An oil collecting groove 25 is provided on the furnace body 21 of the oven 20. The oil collecting groove 25 is used to receive the oil droplets discharged from the baking net 10 and guide the oil droplets into the oil collecting container 30, so as to effectively collect the grease generated during the barbecue process, reduce pollution and improve the usage convenience.

[0047] Furthermore, in this embodiment, an installation groove 27 is designed on the front side of the furnace body 21 of the oven 20. A grease collection container 30 is detachably installed inside the installation groove 27, facilitating the user to take out and clean. A fuel tank 24 is provided in the middle area of the furnace body 21, which is used to accommodate fuel to provide the necessary heat source. In this embodiment, the heat source comes from gas. For example, in some embodiments, the fuel is a combustible solid or liquid, while in other embodiments, the fuel source is an electric heating device to meet the requirements of different usage scenarios. The grill 10 is suspended above the fuel tank 24 so that the food can be fully heated. In addition, a storage rack 23 is also provided on the furnace body 21, which is used to place food ingredients, seasonings or cooking tools, facilitating the user's operation.

[0048] An oil collection groove 25 is provided along the transverse direction on the front side of the furnace body 21 of the oven 20. A plurality of drainage holes 26 are provided inside the oil collection groove 25, enabling the collected grease to smoothly flow into the grease collection container 30. To optimize the grease collection effect, the grill 10 is arranged in an inclined manner with the front end lower and the rear end higher, and its front end is located directly above the oil collection groove 25. In this way, the grease generated during barbecue will flow along the inclined direction of the grill 10, finally converging into the oil collection groove 25 and naturally dripping into the grease collection container 30 through the drainage holes 26 of the oil collection groove 25, ensuring the cleanliness inside the oven 20. In some other embodiments, the grease collection container 30 can be suspended on one side of the furnace body 21 to adapt to different installation requirements. At this time, the bottom of the oil collection groove 25 is designed to be inclined so that the grease can smoothly flow towards the grease collection container 30, improving the grease collection efficiency.

[0049] Further, in this embodiment, an openable and closable upper cover 22 is installed on the furnace body 21 of the oven 20. This upper cover 22 can not only prevent grease from splashing out, but also close the furnace body 21 when needed to maintain the internal temperature, improve the barbecue efficiency, and reduce heat dissipation, thereby improving the barbecue effect.

Provide a metal sheet and process it to form through holes and an oil receiving groove; S2. Further process the metal sheet using a bending process to make it present a wavy mesh surface structure.

[0051] Among them, the formation of the through holes is completed by punching process, and the oil receiving groove is manufactured by a louver process.

It can either punch the holes first and then process the oil receiving groove, or form the oil receiving groove first and then punch the holes. In addition, through a synchronous processing process using the same set of dies, the through holes and the oil receiving groove can be formed simultaneously to improve production efficiency.
