Description

Technical Field

[0001] This invention relates to the field of barbecue equipment technology, and in particular to a sunken heating plate. Background Technology

[0002] In the use of barbecue equipment, to optimize the grilling experience and improve safety and health, heating plates are widely used below the grill grates as a core component of indirect grilling. Their main function is to convert the high temperature of the open flame into gentle and even heat, transferring it to the grill grates above. This prevents food from burning or turning black due to direct contact with the flames, ensuring the food's appearance and taste. Simultaneously, the heating plate catches dripping grease during grilling, preventing it from directly igniting the flames and causing a fire, effectively reducing smoke production and improving the cleanliness of the grilling environment. Furthermore, the heating plate creates a stable heat radiation environment during heating, and the grease dripping onto it produces a small amount of steam. This environment helps retain moisture in the food, preventing it from becoming dry and hard, achieving a crispy exterior and tender interior. Therefore, using heating plates for indirect grilling has become a healthier and more convenient grilling method.

[0003] However, in actual use, the heating plate needs to be in direct contact with the open flame. The heat distribution of the open flame is difficult to achieve perfectly uniformly, leading to uneven heating in certain areas. Due to the material properties of the heating plate, these localized heating differences cause inconsistent thermal expansion and contraction in different areas, making the heating plate prone to warping and deformation after prolonged or repeated use. Since the grill grating is usually placed directly above the heating plate to reduce heat loss and improve grilling efficiency, the warping of the heating plate is directly transmitted to the grating, causing it to tilt. On one hand, when placing food on the grating, the food will slide towards the lower side due to gravity, making it unstable, especially for small pieces of food (such as skewers, small pieces of vegetables, and seafood), which are prone to slipping and piling up. On the other hand, the tilted grating causes uneven heating in different areas, affecting the taste of the food and the grilling effect. Summary of the Invention

[0004] The main objective of this invention is to provide a recessed heating plate that reduces the adverse effects of heating plate warping, optimizes the grilling experience, and ensures consistent quality of grilled food.

[0005] To achieve the above objectives, the recessed hot plate proposed in this invention includes:

[0006] A heating plate having a plurality of evenly distributed air holes; and A support plate is connected to the heating plate and located on opposite sides of the heating plate. The upper surface of the support plate is higher than the upper surface of the heating plate. The support plate is used to support the barbecue grill plate.

[0007] In one embodiment, the upper surface of the support plate is disposed close to the upper surface of the heating plate.

[0008] In one embodiment, the support plate includes a first flat plate and a mounting plate connected to each other; The first flat plate is arranged parallel to the heating plate and is used to support the barbecue grill plate; The mounting plate is connected to the heating plate and is set at an angle to the first flat plate.

[0009] In one embodiment, the mounting plate has mounting holes, and the heating plate has mounting protrusions; The mounting protrusion engages with the mounting socket.

[0010] In one embodiment, the support plate further includes a second flat plate; The second plate is connected to the mounting plate and is set at an angle to the mounting plate. The second plate extends away from the first plate and abuts against the lower end surface of the heating plate.

[0011] In one embodiment, the second plate is arranged parallel to the heating plate, and the upper end surface of the second plate abuts against the lower end surface of the heating plate.

[0012] In one embodiment, the heating plate is corrugated and has a groove and a top; The pores are evenly distributed on the top.

[0013] In one embodiment, the hot plate has an oil drain hole formed in the groove and disposed near the support plate.

[0014] In one embodiment, the heating plate has a lifting side; The lifting side is located on the side of the heating plate and is perpendicular to the support plate.

[0015] In one embodiment, the lifting side is formed with a gripping notch for fingers to pass through.

[0016] In the technical solution of this invention, the sunken hot plate includes a heating plate and a support plate. The support plate supports the grill grating and is higher than the heating plate. This ensures that when the grill grating is placed on the support plate, a certain distance is formed between the grill grating and the heating plate. This prevents the grill grating from being affected by the warping of the heating plate under long-term or frequent use. Furthermore, this distance also prevents the grill grating or food from being directly pressed on the vents, avoiding excessively high local temperatures in the area directly opposite the vents, and thus preventing the food from being charred or blackened in spots. In summary, the sunken hot plate proposed in this solution can prevent the grill grating from being affected by the warping of the heating plate, thus ensuring a stable grilling experience and the quality of the grilled food.

[0024] This invention proposes a sunken heating plate 100. Figures 1 to 2 This is one embodiment of the present invention.

[0025] In this embodiment of the invention, the sunken hot plate 100 includes a heating plate 1 and a support plate 2. The heating plate 1 has a plurality of evenly distributed air holes 11. The support plate 2 is connected to the heating plate 1 and is located on opposite sides of the heating plate 1. The upper end surface of the support plate 2 is higher than the upper end surface of the heating plate 1. The support plate 2 is used to support the grilling grill plate.

[0026] In the technical solution of this invention, the sunken hot plate 100 includes a heating plate 1 and a support plate 2. The support plate 2 is used to support the grilling grating and is higher than the heating plate 1. This ensures that when the grilling grating is placed on the support plate 2, a certain distance is formed between the grilling grating and the heating plate 1. This prevents the grilling grating or food from being directly pressed on the air holes 11, thus avoiding excessively high local temperatures in the area directly opposite the air holes 11 and preventing the food from being charred or blackened. In summary, the sunken hot plate 100 proposed in this solution can prevent the grilling grating from being affected by the warping of the heating plate 1, thereby ensuring a stable grilling experience and the quality of the grilled food.

[0027] It should be noted that a heating plate 1 is usually equipped with two support plates 2 for joint use. The two support plates 2 are respectively set on opposite sides of the heating plate 1 so as to connect the heating plate 1 at both ends and support the grill plate at the same time, making the grill plate more stable.

[0028] In one embodiment, such as Figure 2As shown, the upper surface of the support plate 2 is positioned close to the upper surface of the heating plate 1. That is, although the upper surface of the support plate 2 is higher than the upper surface of the heating plate 1, the distance between them is relatively small. This allows the grilling grating to be placed on the recessed heating plate 100 while maintaining a reasonable spacing between the grilling grating and the heating plate 1. This ensures that the heat radiation and micro-steam generated by the heating plate 1 act more efficiently on the food on the grilling grating, preventing the grilling grating from directly pressing against the heating plate 1 and causing warping. It also ensures the heat transfer efficiency of the heating plate 1, preventing significant heat loss due to excessive gaps, thereby improving the grilling effect.

[0029] In one embodiment, such as Figure 1 As shown, the support plate 2 includes a first flat plate 21 and a mounting plate 22 connected to each other. The first flat plate 21 is arranged parallel to the heating plate 1 and is used to support the grill grating. The mounting plate 22 is connected to the heating plate 1 and is arranged at an angle to the first flat plate 21. By setting the angle between the first flat plate 21 and the mounting plate 22, the heating plate 1 can be installed on the mounting plate 22 while still ensuring that the first flat plate 21 is parallel to the heating plate 1. According to customer needs, during the manufacturing process of the sunken heating plate 100, the mounting structure on the mounting plate 22 can be set at different height distances from the upper end face of the first flat plate 21. This allows the heating plate 1 to achieve a preset height interval with the upper end face of the first flat plate 21 when assembled with the mounting plate 22. Placing the grill grating on the first flat plate 21 makes the heating of each part of the grill grating more uniform.

[0030] In one embodiment, the mounting plate 22 has mounting holes, and the heating plate 1 has mounting protrusions; the mounting protrusions and mounting holes are interlocked. Through the interlocking of the mounting protrusions and mounting holes, rapid positioning and secure connection between the heating plate 1 and the support plate 2 are achieved, simplifying the assembly process, improving assembly efficiency, and facilitating the production and transportation of the sunken heating plate 100. The heating plate 1 and support plate 2 can be manufactured separately, reducing overall production difficulty. When purchased and used by the user, only simple assembly is required before use. Furthermore, they are shipped and transported as components. Compared to overall production, the heating plate 1 and support plate 2 are less prone to deformation or damage during transportation, providing convenience for production and transportation. Simultaneously, they maintain stable connection even in high-temperature operating environments, preventing relative displacement between the support plate 2 and the heating plate 1 and ensuring structural reliability.

[0031] In one embodiment, the heating plate 1 and the support plate 2 are pre-installed and positioned by the insertion and engagement of the aforementioned mounting protrusions and mounting holes, and then reinforced by welding, thereby achieving a higher connection strength between them. The welding points are not limited to the pre-installation positioning points; to facilitate welding, multiple welds can be made at the contact points between the support plate 2 and the top 13 of the heating plate 1 to ensure a firm connection.

[0032] In one embodiment, at least two mounting protrusions are provided on the same side of the heating plate 1, and at least two mounting holes are provided on each mounting plate 22 to cooperate with them. This redundant design not only improves the connection strength between the two, but also improves the structural stability during use. Even if individual mounting structures are damaged, the normal connection between the heating plate 1 and the support plate 2 will not be affected.

[0033] In one embodiment, such as Figure 1 As shown, the support plate 2 also includes a second flat plate 23; the second flat plate 23 is connected to the mounting plate 22 and is set at an angle to the mounting plate 22. The second flat plate 23 extends in a direction away from the first flat plate 21 and abuts against the lower end surface of the heating plate 1. Based on the connection between the support plate 2 and the heating plate 1, the second flat plate 23 is further designed to support and limit the heating plate 1 from below, ensuring that the heating plate 1 is stably installed between the support plates 2, thereby improving the overall strength and structural connection stability of the recessed heating plate 100.

[0034] In one embodiment, such as Figure 2 As shown, the second plate 23 is arranged parallel to the heating plate 1, with its upper surface abutting against the lower surface of the heating plate 1. Based on the second plate 23 supporting the heating plate 1 from below, the parallelism between the second plate 23 and the heating plate 1 is further defined, maximizing the contact area between them. This surface contact, distinct from point and line contact, provides optimal support, resulting in a more uniform applied support force. It effectively disperses the stress generated by the heating plate 1 under heat, further suppressing warping and deformation of the heating plate 1. Simultaneously, it ensures a tight fit and stable stress distribution between the heating plate 1 and the support plate 2, extending their service life.

[0035] In one embodiment, such as Figure 1As shown, the heating plate 1 is wavy and has a groove 12 and a top 13; vents 11 are evenly distributed on the top 13. The wavy structure itself forms multiple reinforcing ribs, which has higher structural strength than a flat structure. It has higher resistance to deformation when heated and is not easily deformed, sag, or cracked at high temperatures. The wavy grooves can stabilize the flame, allowing for more complete mixing of gas and air, resulting in more complete combustion and thus achieving energy saving. The vents 11 on the top 13 facilitate the upward and even application of hot air and steam to the food, while the groove 12 facilitates the flow of oil, achieving dual optimization of heating and oil guiding. The lower end of the wavy heating plate 1 is closer to the heat source, which helps to improve the heating effect. Moreover, the lowering height of the heating plate 1 is matched with the thickness of the grill grating, so that the grill grating is flush with the oven frame after assembly and does not protrude from the oven surface, resulting in a flat and uniform appearance.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the heating plate 1 has an oil drain hole 14 formed in the groove 12 and located near the support plate 2. The groove 12 facilitates grease collection, and the oil drain hole 14 allows the collected grease to be discharged in a timely manner, preventing grease from accumulating on the heating plate 1 and generating a large amount of oil smoke or posing a fire hazard. Furthermore, the oil drain hole 14 is positioned near the support plate 2, specifically near both ends of the heating plate 1. This arrangement avoids the main heating area in the middle of the heating plate 1. When grease is discharged through the oil drain hole 14, it avoids the central flame, controlling the generation of high-temperature oil smoke and not affecting the normal use of the central grilling area, thus improving safety and cleanliness. During the grilling process, a collection device can also be installed below the oil drain hole 14 to collect the discharged grease in a timely manner, further enhancing safety and the overall cleanliness of the equipment.

[0037] In one embodiment, such as Figure 1 As shown, the heating plate 1 has a lifting side 15; the lifting side 15 is located on the side of the heating plate 1 and is perpendicular to the support plate 2. That is, the lifting side 15 is located at the edge of the heating plate 1 that is different from the edge connected to the support plate 2. The lifting side 15 makes it easy for the user to hold and move the sunken heating plate 100, which facilitates the installation and position adjustment of the sunken heating plate 100, and does not interfere with the support plate 2 or the grill grill plate, further improving the ease of use and safety of the sunken heating plate 100.

[0038] In one embodiment, such as Figure 1As shown, the handle side 15 has a grip notch 151 for fingers to pass through. In actual grilling, more than one sunken heating plate 100 may be placed in the same oven. When multiple sunken heating plates 100 are placed side by side, their structure is compact, and there is no gap between each sunken heating plate 100, making it difficult to install, disassemble, and adjust the position of the sunken heating plates 100. With the grip notch 151 on the handle side 15, the user can directly or indirectly with gloves or other protective gear pass their fingers through the grip notch 151 from top to bottom to pinch the handle side 15. This makes it easier for the user to hold the handle side 15 stably and firmly, and makes it easier and less likely to slip when removing the sunken heating plate 100, further improving operational safety and ease of use.

[0039] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
