Description

Technical Field

[0001] This utility model belongs to the field of gas appliance technology, specifically relating to an energy-concentrating pot rack and a gas stove. Background Technology

[0002] Existing heat-concentrating pan supports typically consist of upper and lower layers, using a ring-shaped enclosure to concentrate the flame and accelerate heat transfer, thereby improving heating efficiency and uniformity. However, in current technology, the upper heat-concentrating pan often employs complex structures such as multiple bends at the edges to achieve positioning, heat conduction, or connection functions. Such complex structures not only increase the difficulty of processing and assembly but also easily create cleaning dead zones at the structural joints, making thorough cleaning difficult after use and affecting service life and hygiene performance.

[0003] Furthermore, complex edge structures require high precision in the fit between components, which is not conducive to achieving simplified, integrated structural designs. The more complex the structural form, the more difficult it is to achieve integral molding through processes such as mold pressing, limiting the application of structures suitable for easy-to-clean materials and reducing the efficiency and consistency of mass production, thereby affecting the product's ability to be promoted in large-scale production and application.

[0004] Therefore, how to design a simple and easy-to-clean energy-concentrating pot rack has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] This utility model provides an energy-concentrating pot rack, which aims to solve the problem that the existing energy-concentrating pot racks have a relatively complex structure, have many cleaning dead corners, and make it difficult to thoroughly clean the oil stains on the surface after use.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A heat-concentrating pan rack includes a lower heat-concentrating pan and an upper heat-concentrating pan that are detachably connected to form a hollow heat-insulating structure. The lower heat-concentrating pan includes an outer ring wall, a bottom wall, and an inner ring wall that is lower than the outer ring wall, which are connected in sequence. The upper heat-concentrating pan overlaps the outer ring wall, and the inner periphery of the upper heat-concentrating pan extends near the top of the inner ring wall.

[0009] Furthermore, a gap is provided between the inner periphery of the upper energy-concentrating disk and the outer periphery of the inner ring wall, or the inner periphery of the upper energy-concentrating disk overlaps with the inner ring wall.

[0010] Furthermore, the inner ring wall extends obliquely from bottom to top along the axis close to the upper energy-concentrating disk; the inner ring wall is higher than the inner periphery of the upper energy-concentrating disk, or the top of the inner ring wall is flush with the top of the inner periphery of the upper energy-concentrating disk.

[0011] Furthermore, the width of the gap between the upper energy-concentrating disk and the inner ring wall in the horizontal direction is less than or equal to the horizontal distance between the outer periphery of the upper energy-concentrating disk and the inner periphery of the outer ring wall.

[0012] Furthermore, the upper energy-concentrating disk is disc-shaped, including: a first annular plate and a third annular plate extending along its circumference, the third annular plate being disposed below the first annular plate and having an outer diameter smaller than the inner diameter of the first annular plate;

[0013] And a second annular plate connecting the inner periphery of the first annular plate and the outer periphery of the third annular plate.

[0014] Furthermore, the second annular plate bends and extends upward along the axis away from the upper energy-concentrating disk.

[0015] Furthermore, the connection between the outer periphery of the second annular plate and the inner periphery of the first annular plate is an arc-shaped transition structure; and / or, the connection between the inner periphery of the second annular plate and the outer periphery of the third annular plate is an arc-shaped transition structure.

[0016] Furthermore, the top of the outer ring wall of the lower energy-concentrating disk bends and extends away from its axis.

[0017] Furthermore, the upper energy-concentrating plate is a one-piece molded glass or ceramic plate.

[0018] Another objective of this utility model is to provide a gas stove equipped with the aforementioned energy-concentrating pot rack.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0020] 1. This utility model simplifies the structure of the upper energy-concentrating plate by setting the outer periphery of the upper energy-concentrating plate to overlap the outer periphery of the lower energy-concentrating plate, and the inner periphery of the lower energy-concentrating plate is provided with an upwardly inclined inner ring wall. The inner periphery of the upper energy-concentrating plate is fitted onto the outer periphery of the inner ring wall. On the one hand, it can avoid the formation of cleaning dead corners and facilitate cleaning after use. On the other hand, it is also more suitable for using glass plates or ceramic plates to be molded into upper energy-concentrating plates.

[0021] 2. This utility model, by setting a certain gap between the inner circumference of the upper energy-concentrating disk and the inner ring wall, avoids the formation of dead corners for oil stains to accumulate at the bottom of the inner circumference of the upper energy-concentrating disk, which is conducive to daily cleaning; at the same time, during use, oil stains can flow downward along the inclined inner surface formed by the downward indentation of the upper energy-concentrating disk, and drip into the lower energy-concentrating disk through the gap between the inner circumference of the upper energy-concentrating disk and the inner ring wall.

[0022] 3. By setting the width of the gap between the inner periphery of the upper energy-concentrating disk and the inner ring wall in the horizontal direction to be less than or equal to the horizontal distance between the outer periphery of the upper energy-concentrating disk and the inner periphery of the outer ring wall, this utility model can effectively limit the problem of gaps between the outer periphery of the upper energy-concentrating disk and the outer ring wall caused by slight shaking, thermal deformation or assembly tolerance during use, thereby preventing flames, hot gas or oil from leaking out from the gaps.

[0023] 4. This utility model sets the angle between the extension direction of the third annular plate and the axial extension direction of the upper energy-concentrating disk to be less than or equal to 90 degrees. When the angle between the extension direction of the third annular plate and the axial extension direction of the upper energy-concentrating disk is less than 90 degrees, it can accelerate the flow of oil stains on the surface of the upper energy-concentrating disk to the gap. When the angle between the extension direction of the third annular plate and the axial extension direction of the upper energy-concentrating disk is equal to 90 degrees, that is, the third annular plate is parallel to the first annular plate, which is more conducive to processing.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figures 1 to 6 As shown in the figure, this embodiment discloses an energy-concentrating pot rack and a gas stove, wherein the gas stove can be a household gas stove, a built-in stove, an integrated stove, a tabletop stove, or an industrial stove, etc.

[0042] like Figures 1 to 6As shown in the embodiment of this utility model, the energy-concentrating pot rack includes at least two layers of energy-concentrating plates, which are used to improve the heat energy concentration efficiency of the gas stove. This embodiment takes the energy-concentrating pot rack including two layers of energy-concentrating plates as an example for specific description. The two layers of energy-concentrating plates are an upper energy-concentrating plate 1 and a lower energy-concentrating plate 2, which are arranged sequentially in the vertical direction and achieve positioning support and heat flow guidance functions through structural cooperation.

[0043] Specifically, in this embodiment of the present invention, the upper energy-concentrating disk 1 and the lower energy-concentrating disk 2 are detachably connected, and a hollow heat-insulating structure is formed between the upper energy-concentrating disk 1 and the lower energy-concentrating disk 2. The hollow heat-insulating structure forms an annular channel, which helps the flame heat flow around and focus during use, thereby improving the heat energy utilization efficiency.

[0044] More specifically, in this embodiment of the present invention, the lower energy-concentrating disk 2 is provided with a plurality of support feet 20, which are arranged at intervals along the circumference of the lower energy-concentrating disk 2. Each support foot 20 is inserted into a corresponding positioning groove 10 on the upper energy-concentrating disk 1. The lower energy-concentrating disk 2 and the upper energy-concentrating disk 1 are connected by an insertion joint to achieve positioning support of the upper energy-concentrating disk 1 by the lower energy-concentrating disk 2, while limiting the relative displacement between the two and ensuring the stability of their assembly.

[0045] In this embodiment of the present invention, the lower energy-concentrating disk 2 includes an outer ring wall 21, a bottom wall 22 and an inner ring wall 23 that is lower than the outer ring wall 21, which are connected in sequence; the upper energy-concentrating disk 1 overlaps the outer ring wall 21 of the lower energy-concentrating disk 2, and the inner periphery of the upper energy-concentrating disk 1 extends close to the top of the inner ring wall 23.

[0046] Specifically, in this embodiment of the present invention, the inner ring wall 23 extends obliquely from bottom to top along the direction close to the axis of the upper energy-concentrating disk 1; further, the outer periphery of the upper energy-concentrating disk 1 extends radially and overlaps the outer ring wall 21; while the inner periphery of the lower energy-concentrating disk 2 is provided with an upwardly obliquely extending inner ring wall 23, the inner ring wall 23 being higher than the inner periphery of the upper energy-concentrating disk 1, or the top of the inner ring wall 23 being flush with the top of the inner periphery of the energy-concentrating disk.

[0047] Through the above design, the overall structure of the upper energy-concentrating plate 1 is simpler. On the one hand, it avoids the complex multi-bending design common in traditional structures, eliminates the formation of cleaning dead corners, and makes it easier for users to remove oil stains and other residues from the surface of the upper energy-concentrating plate 1 after use. On the other hand, since traditional energy-concentrating plates usually use a metal body combined with an enamel layer, there is a problem that the enamel surface is difficult to clean thoroughly. However, in this embodiment, due to the simplification of the structure of the upper energy-concentrating plate 1, it is easy to use an integrally pressed ceramic plate or glass plate structure, which has the advantages of high temperature resistance and easy cleaning, improving the applicability of the product and the adaptability of the manufacturing process.

[0048] like Figures 1 to 4As shown in the embodiment of this utility model, a gap 4 is provided between the inner periphery of the upper energy-concentrating disk 1 and the outer periphery of the inner ring wall 23. This gap does not constitute a sealed fit and does not cause structural interference. This avoids the formation of dead corners for oil accumulation in the inner periphery of the upper energy-concentrating disk 1, which is beneficial for daily cleaning. At the same time, during use, oil can flow downwards along the inclined inner surface formed by the downward indentation of the upper energy-concentrating disk 1, and drip into the lower energy-concentrating disk 2 through the gap 4 between the inner periphery of the upper energy-concentrating disk 1 and the inner ring wall 23, reducing the residue of oil in the upper energy-concentrating disk 1 and maintaining its aesthetic appearance. After a certain amount of oil accumulates inside the lower energy-concentrating disk 2, it can be cleaned in a concentrated manner, improving the overall ease of use.

[0049] Specifically, in this embodiment of the present invention, the gap 4 between the inner periphery of the upper energy-concentrating plate 1 and the inner ring wall 23 of the lower energy-concentrating plate 2, in the horizontal direction, is less than or equal to the horizontal distance between the outer periphery of the upper energy-concentrating plate 1 and the inner periphery of the outer ring wall 21. This effectively limits the lateral displacement of the upper energy-concentrating plate 1 caused by slight shaking, thermal deformation, or assembly tolerances during use. This avoids the problem of gaps appearing between the outer periphery of the upper energy-concentrating plate 1 and the outer ring wall 21 due to the lateral displacement of the upper energy-concentrating plate 1, improves the integrity and appearance consistency of the structural connection, prevents flames and hot air from leaking out from the gaps, improves the heat-concentrating efficiency, and also helps the cookware to be heated evenly and stably.

[0050] In another embodiment, the inner periphery of the upper energy-concentrating disk 1 overlaps with the inner ring wall 23; specifically, the outer wall surface of the inner ring wall 23 contacts the inner periphery of the upper energy-concentrating disk 1, which can further enhance the positioning stability of the upper energy-concentrating disk 1 and help improve the assembly reliability and durability of the overall structure.

[0051] In this embodiment of the present invention, the upper energy-concentrating disk 1 is disc-shaped and includes a first annular plate 11, a second annular plate 12 and a third annular plate 13 connected sequentially from top to bottom.

[0052] Specifically, in this embodiment of the present invention, the first annular plate 11 and the third annular plate 13 extend circumferentially along the upper energy-concentrating disk 1. The third annular plate 13 is disposed below the first annular plate 11 and its outer diameter is smaller than the inner diameter of the first annular plate 11. The first annular plate 11 forms the top edge of the upper energy-concentrating disk 1. The second annular plate 12 is connected between the inner circumference of the first annular plate 11 and the outer circumference of the third annular plate 13. This allows the oil to slide smoothly to the gap 4 between the third annular plate 13 and the inner ring wall 23 and drip from the gap 4 into the lower energy-concentrating disk 2, reducing the time that the oil stays in the upper energy-concentrating disk 1 and preventing the oil from remaining on the upper energy-concentrating disk 1 after cooling.

[0053] More specifically, in this embodiment of the present invention, the angle between the extending direction of the third annular plate 13 and the extending direction of the axis of the upper energy-concentrating disk 1 is less than or equal to 90 degrees.

[0054] When the angle between the extension direction of the third annular plate 13 and the axial extension direction of the upper energy-concentrating disk 1 is less than 90 degrees, it can accelerate the flow of oil stains on the surface of the upper energy-concentrating disk 1 to the gap 4; when the angle between the extension direction of the third annular plate 13 and the axial extension direction of the upper energy-concentrating disk 1 is equal to 90 degrees, that is, the third annular plate 13 is parallel to the first annular plate 11, it is more conducive to processing.

[0055] In this embodiment of the present invention, the connection between the outer periphery of the second annular plate 12 and the inner periphery of the first annular plate 11 is an arc-shaped transition structure; and / or, the connection between the inner periphery of the second annular plate 12 and the outer periphery of the third annular plate 13 is an arc-shaped transition structure.

[0056] Preferably, in this embodiment of the present invention, the connection between the first annular plate 11, the second annular plate 12 and the third annular plate 13 connected in sequence are all arc-shaped transition structures, which further makes the overall structure of the upper energy-concentrating disk 1 smoother and simpler, and easier to process and clean.

[0057] Specifically, in this embodiment of the present invention, the second annular plate 12 between the first annular plate 11 and the third annular plate 13 bends and extends upward along the axial direction away from the upper energy-concentrating disk 1, further increasing the surface smoothness of the upper energy-concentrating disk 1. The second annular plate 12 together with the first annular plate 11 and the third annular plate 13 form a smooth upper energy-concentrating disk 1.

[0058] In this embodiment of the invention, the top of the outer ring wall 21 of the lower energy-concentrating disk 2 bends and extends away from its axis to overlap with the upper energy-concentrating disk 1. When the upper energy-concentrating disk 1 overlaps with the lower energy-concentrating disk 2, the bottom end of its first annular plate 11 is in contact with the upper end face of the bent and extended portion of the outer ring wall 21, achieving stable horizontal support contact and enhancing the structural connection reliability between the lower energy-concentrating disk 2 and the upper energy-concentrating disk 1.

[0059] Specifically, in this embodiment of the invention, the outer ring wall 21 of the lower energy-concentrating plate 2 extends horizontally along the radial direction (i.e., outward from the center) at its top edge, forming a circular unfolded state. This ensures that the entire bent portion is arranged in a basically horizontal position when installed and used on the stove. Simultaneously, the top bend of the outer ring wall 21 connects to the main body of the outer ring wall through an arc-shaped transition. The transition area has no sharp corners or folds, presenting a smooth curved surface structure, effectively preventing the accumulation of dirt in the connection gaps. Furthermore, it facilitates natural cleaning with a cleaning cloth or water flow during use, improving overall hygiene performance.

[0060] In this embodiment of the present invention, the bottom wall 22 of the lower energy-concentrating disk 2 includes a first bottom wall 22 extending downward toward its axis and a second bottom wall 22 extending radially. The outer periphery of the first bottom wall 22 is connected to the inner periphery of the outer ring wall 21, and the inner periphery of the second bottom wall 22 is connected to the outer periphery of the inner ring wall 23.

[0061] Specifically, the angle between the extension direction of the first bottom wall 22 and the extension direction of the second bottom wall 22 is greater than 90 degrees.

[0062] Preferably, the connection between the outer ring wall 21, the first bottom wall 22, the second bottom wall 22, and the inner ring wall 23 is an arc-shaped transition structure.

[0063] In this embodiment of the utility model, the lower energy-concentrating disk 2 has four support feet 20 evenly distributed along its circumference. The four support feet 20 are arranged symmetrically with each other, specifically in pairs facing each other, forming a stable support structure.

[0064] Specifically, in this embodiment of the present invention, the bottom of the support foot 20 is connected to the bent extension area at the top of the outer ring wall 21 of the lower energy-concentrating disk 2, so that the support foot 20 can directly support the edge reinforcement part of the lower energy-concentrating disk 2, thereby improving the overall support stability and structural strength.

[0065] In another specific embodiment, only two support feet 20 may be provided, positioned opposite each other on both sides of the lower energy-concentrating plate 2. This further simplifies the overall structure of the energy-concentrating plate and pot rack, making it suitable for stove systems with high requirements for lightweight structure or component versatility. This reduces manufacturing costs and improves assembly efficiency. Although the number of supports is reduced, the basic stability of the lower energy-concentrating plate 2 during normal use can still be ensured by optimizing the position and structural strength of the support feet 20.

[0066] In another possible implementation, the number of support feet 20 can be set to four or more, evenly distributed along the circumferential direction of the lower energy-concentrating plate 2. Increasing the number of support points helps to further improve the structural support strength and stability, especially suitable for use scenarios where the lower energy-concentrating plate 2 has a large diameter or supports heavy cookware. Through multi-point support, not only can structural shaking or deformation caused by cookware misalignment be effectively prevented, but the overall resistance to thermal expansion and contraction after heating can also be improved, further extending the product's service life.

[0067] In this embodiment, the bottom of the lower energy-concentrating plate 2 is also provided with feet 3 for supporting the overall structure. The feet 3 are located on the lower surface of the lower energy-concentrating plate 2 and are preferably evenly distributed along its circumference. They are used to support the pot rack of the energy-concentrating plate on the stove platform or other mounting base during use, thereby improving the overall structural stability and preventing slippage and tilting. The feet 3 can be integrally formed or assembled separately, and their height can be adjusted according to the stove structure to ensure that the lower energy-concentrating plate 2 maintains a reasonable distance from the heat source, thus achieving good heat utilization and structural support.

[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
