[0050] This utility model embodiment provides a stove rack that is compatible with both flat-bottomed pans and curved-bottomed pans 300, while improving the assembly and disassembly performance of the stove rack and enhancing its stability and reliability.

[0051] like Figures 1 to 4As shown, the furnace frame includes an annular base 200 and support components 100, with multiple support components 100 spaced circumferentially along the annular base 200. Each support component 100 includes a fixed furnace ear 1, a connecting shaft 3, and a movable furnace ear 2. The fixed furnace ear 1 is connected to the annular base 200, and the movable furnace ear 2 is rotatably mounted on the fixed furnace ear 1 via the connecting shaft 3, allowing the movable furnace ear 2 to rotate and switch between a first position and a second position.

[0052] The connecting shaft 3 passes through the fixed furnace ear 1 and the movable furnace ear 2, and the connecting shaft 3 is provided with a plurality of first stop structures 35 and at least one second stop structure 4 at intervals along its axial direction. The fixed furnace ear 1 and the movable furnace ear 2 abut against a first stop structure 35 on the same side along the axial direction of the connecting shaft 3, and the other side of the fixed furnace ear 1 and / or the other side of the movable furnace ear 2 abut against the second stop structure 4. The first stop structure 35 restricts the corresponding fixed furnace ear 1 or movable furnace ear 2 from moving along the first axial direction, and the second stop structure 4 restricts the corresponding fixed furnace ear 1 or movable furnace ear 2 from moving along the second axial direction. The first axial direction and the second axial direction are opposite.

[0053] The furnace frame provided in this embodiment has a fixed furnace ear 1 and a movable furnace ear 2 rotatably connected by a connecting shaft 3. The connecting shaft 3 is provided with a plurality of first stop structures 35 and at least one second stop structure 4 that abut against the fixed furnace ear 1 and the movable furnace ear 2. The first stop structure 35 can restrict the fixed furnace ear 1 and the movable furnace ear 2 from moving relative to the connecting shaft 3 along the first axial direction, and the second stop structure 4 can restrict the fixed furnace ear 1 and / or the movable furnace ear 2 from moving relative to the connecting shaft 3 along the second axial direction. This allows the fixed furnace ear 1 and the movable furnace ear 2 to be stably assembled on the connecting shaft 3, thereby preventing the connecting shaft 3 and the movable furnace ear 2 from separating relative to the fixed furnace ear 1. This ensures the installation stability and reliability of the movable furnace ear 2 relative to the fixed furnace ear 1, thereby improving the structural stability and reliability of the furnace frame.

[0054] In one embodiment, when the movable stove lug 2 is in the first position, the movable stove lug 2 can support the flat-bottomed pan; when the movable stove lug 2 is in the second position, the movable stove lug 2 can support the curved-bottomed pan 300. In other embodiments, when the movable stove lug 2 is in the first position, the fixed stove lug 1 supports the flat-bottomed pan, and when the movable stove lug 2 is in the second position, the movable stove lug 2 can support the curved-bottomed pan 300.

[0055] like Figures 5 to 8As shown, to further improve the assembly stability and reliability of the movable furnace ear 2 and the fixed furnace ear 1, in one embodiment, the movable furnace ear 2 includes two ear plate portions 21 arranged opposite to each other and spaced apart, and a support plate portion 22 connected between the two ear plate portions 21. The connecting shaft 3 passes through the two ear plate portions 21, the fixed furnace ear 1 is located between the two ear plate portions 21, and the support plate portion 22 is located above the fixed furnace ear 1. The two ear plate portions 21 abut against two first stop structures 35 on the side facing the first axial direction; the fixed furnace ear 1 abuts against a second stop structure 4 on the side facing the second axial direction; and / or, the ear plate portion 21 located on the side of the fixed furnace ear 1 along the second axial direction abuts against the second stop structure 4.

[0056] By providing a movable furnace ear 2 with two ear plates 21, and with the two ear plates 21 located on opposite sides of the fixed furnace ear 1, the overall structural strength and rigidity of the movable furnace ear 2 can be enhanced, the probability of deformation under stress can be reduced, and the support performance of the movable furnace ear 2 for cookware can be improved, thereby improving the stability and reliability of the furnace frame. In other embodiments, the movable furnace ear 2 may also include only one ear plate 21 and a support plate 22 connected to the ear plate 21.

[0057] For ease of subsequent description, the ear plate portion 21 located on the side of the fixed furnace ear 1 facing the second axis is referred to as the first ear plate portion 21a, and the other ear plate portion 21 is referred to as the second ear plate portion 21b.

[0058] In one embodiment, the connecting shaft 3 includes multiple shaft segments that increase sequentially in outer diameter along a first axial direction. The shoulders of two adjacent shaft segments form a first locking structure, and the fixed furnace ear 1 and the movable furnace ear 2 are installed on different shaft segments. This arrangement simplifies the structure of the furnace frame and improves the ease of assembly between the connecting shaft 3 and the fixed furnace ear 1 and the movable furnace ear 2.

[0059] In one embodiment, the fixed furnace ear 1 is provided with a fixed shaft hole 14, and the movable furnace ear 2 is provided with a rotating shaft hole 211. The fixed shaft hole 14 is clearance-fitted with the corresponding shaft segment and / or the rotating shaft hole 211 is spaced-fitted with the corresponding shaft segment, so as to further ensure the assembly stability of the connecting shaft 3, the movable furnace ear 2 and the fixed furnace ear 1.

[0060] In one embodiment, the fixed furnace ear 1 is coaxially provided with four shaft segments along a first axis. The four shaft segments are a first shaft segment 31, a second shaft segment 32, a third shaft segment 33, and a fourth shaft segment 34, and the outer diameters of the first shaft segment 31, the second shaft segment 32, the third shaft segment 33, and the fourth shaft segment 34 increase sequentially. A first shoulder is formed at the connection between the first shaft segment 31 and the second shaft segment 32, a second shoulder is formed at the connection between the second shaft segment 32 and the third shaft segment 33, and a third shoulder is formed at the connection between the third shaft segment 33 and the fourth shaft segment 34. The first shoulder, the second shoulder, and the third shoulder are all first stop structures 35. One ear plate portion 21 is installed on the first shaft segment 31 and abuts against the first shoulder, another ear plate portion 21 is installed on the third shaft segment 33 and abuts against the third shoulder, and the fixed furnace ear 1 is installed on the second shaft segment 32 and abuts against the second shoulder.

[0061] The first ear plate portion 21a has a rotating shaft hole 211, which is called the first shaft hole 211a. The second ear plate portion 21b has a shaft hole, which is called the second shaft hole 211b. The size of the second shaft hole 211b is adapted to the size of the third shaft segment 33, and the size of the first shaft segment 31 is adapted to the size of the first shaft hole 211a. This arrangement facilitates the insertion of the fixed furnace ear 1 between the two ear plate portions 21, allowing it to pass sequentially along the second axis through the second shaft hole 211b, the fixed shaft hole 14, and the first shaft hole 211a until each of the first stop structures 35 abuts against the two ear plate portions 21 and the fixed ear portion, thereby improving assembly efficiency.

[0062] In one embodiment, a blind hole 36 is provided at the first end of the connecting shaft 3, and the open end of the blind hole 36 is folded outward to form a limiting flange 4a. The second stop structure 4 includes the limiting flange 4a. Because the opening edge of the blind hole 36 is folded to form a limiting flange 4a, when assembling the support assembly 100, before the limiting flange 4a is folded into shape, the fixed furnace ear 1 and the movable furnace ear 2 can be passed through from the second end to the first end of the connecting shaft 3. Then, by folding the opening edge of the blind hole 36, the fixed furnace ear 1 and the movable furnace ear 2 are prevented from coming off the connecting shaft 3. This confines the fixed furnace ear 1 and the movable furnace ear 2 between the limiting part and the limiting flange 4a, ensuring the installation reliability of the movable furnace ear 2 rotatably mounted on the fixed furnace ear 1 through the connecting shaft 3, while improving the ease of installation and disassembly of the support assembly 100 and the furnace frame. Furthermore, the form of the limiting flange 4a formed by folding the edge of the blind hole 36 is more stable than the existing limiting structure that can be detachably installed on the connecting shaft 3. This makes it less likely for the fixed furnace ear 1 and the movable furnace ear 2 to come loose from the connecting shaft 3. Disassembly and maintenance can also be achieved with tools, and there is no problem of assembly failure due to missing parts. This improves the reliability of assembly while also ensuring the disassembly and maintenance performance of the furnace frame.

[0063] In one embodiment, the second stop structure 4 includes a retaining ring 4b, which is detachably sleeved on the connecting shaft 3. By setting the retaining ring 4b as the second stop structure 4, it is convenient to assemble and disassemble the second stop structure 4 on the connecting shaft 3.

[0064] To further improve the stability and reliability of the furnace frame, in one embodiment, the second stop structure 4 includes a retaining ring 4b and a limiting flange 4a. The limiting flange 4a abuts against the side of the second ear plate portion 21b away from the fixed furnace ear 1, and the retaining ring 4b abuts against the fixed furnace ear 1. This makes the installation position of the fixed furnace ear 1 and the movable furnace ear 2 on the connecting shaft 3 stable, and facilitates the overall assembly and disassembly of the connecting shaft 3 relative to the fixed furnace ear 1 and the movable furnace ear 2.

[0065] In another embodiment, two ear plates 21 are provided, and the second stop structure 4 includes a limiting flange 4a or a retaining ring 4b, which abuts against the first ear plate 21a or the fixed furnace ear 1. In yet another embodiment, only one ear plate 21 may be provided, and the second stop structure 4 includes a limiting flange 4a or a retaining ring 4b, which abuts against the ear plate 21 or the fixed furnace ear 1.

[0066] Specifically, the limiting flange 4a is formed by folding the end of the first shaft segment 31, and the retaining ring 4b is installed on the second shaft segment 32.

[0067] To improve the installation stability of the retaining ring 4b, in one embodiment, an annular groove 321 is provided on the connecting shaft 3, and the retaining ring 4b is engaged in the annular groove 321 to limit the axial movement of the retaining ring 4b along the connecting shaft 3, thereby improving the stability of the second limiting structure on the connecting shaft 3. Specifically, an annular groove 321 is provided on the second shaft segment 32.

[0068] like Figures 1 to 3 and Figures 9 to 11 As shown, in one embodiment, a first support surface 221 is formed on the upper surface of the support plate portion 22. When the movable stove ear 2 is in the first position, the first support surface 221 is horizontally arranged to support the flat-bottomed pan. A second support surface 212 is formed on the side of the ear plate portion 21 away from the support plate portion 22. The second support surfaces 212 of the two ear plate portions 21 are coplanar. When the movable stove ear 2 is in the second position, the second support surface 212 is inclined from top to bottom along the direction of the center of the annular base 200 to support the arc-shaped bottomed pan 300.

[0069] In one embodiment, the ear plate portion 21 includes a first side portion and a second side portion disposed opposite to each other. A support plate portion 22 is connected between the first side portions of the two movable furnace ears 2, and the surface of the second side portion forms a second support surface 212. The distance between the first side portion and the second side portion gradually increases from the first end to the second end of the ear plate portion 21. The rotating shaft hole 211 is disposed near the second end of the ear plate portion 21, thereby reducing the width of the ear plate portion 21 at the first end while ensuring the opening size of the rotating shaft hole 211, thereby reducing the interference between the movable furnace ears 2 and the fixed furnace ears 1, and reducing the overall weight of the furnace frame.

[0070] The second ends of the first and second sides are connected by an arc-shaped side 213. The axis of the arc-shaped side 213 is coaxial with the rotating shaft hole 211, which can ensure the overall strength and rigidity of the movable furnace ear 2 while reducing the size of the movable furnace ear 2.

[0071] In one embodiment, the extension length of the support plate portion 22 along the first side portion is less than the length of the first side portion. That is, the support plate portion 22 extends from the first end of the first side portion and is spaced apart from the second end of the first side portion, so that a through clearance space is formed between the second ends of the two first sides portion and between the two arc-shaped sides 213, so as to avoid the fixed furnace ear 1 during rotation.

[0072] In one embodiment, when the movable stove ear 2 is in the first position, the minimum distance between the support plate portion 22 and the center line of the annular base 200 is less than the minimum distance between the fixed stove ear 1 and the center line. This reduces the diameter of the circle formed by the inner ends of the multiple movable stove ears 2 when the movable stove ear 2 is in the first position, thereby making it more suitable for supporting frying pans of different sizes.

[0073] When the movable burner ear 2 is in the second position, the second support surface 212 extends from bottom to top away from the center line, and the first end of the movable burner ear 2 is higher than the fixed burner ear 1, with the support plate portion 22 located on the side of the second support surface 212 away from the center line. That is, the movable burner ear 2 rotates from the first position to the second position by flipping outwards. This arrangement increases the maximum distance between the second support surface 212 and the center line, thereby better accommodating the support of larger curved-bottom pots 300, allowing the stove rack to better accommodate curved-bottom pots 300 of different sizes.

[0074] To improve the stability of the movable furnace ear 2 in the first position, a first limiting part 11 is provided on the fixed furnace ear 1. When the movable furnace ear 2 is in the first position, the first limiting part 11 abuts against the movable furnace ear 2 to restrict the movable furnace ear 2 from rotating in a direction away from the second position.

[0075] The first limiting part 11 is a horizontal structure located on the upper end of the fixed burner ear 1. When the movable burner ear 2 is in the first position, the lower side of the support plate part 22 is in contact with the first limiting part 11. This increases the contact area between the support plate part 22 and the fixed burner ear 1, better restricting the fixed burner ear 1 from continuing to rotate downward from the first position, ensuring that the first support surface 221 is horizontally set, thereby ensuring the stability and reliability of the support for the frying pan. When the movable burner ear 2 is in the first position, the width of the portion of the first limiting part 11 that is in contact with the support plate part 22 in the radial direction of the annular base 200 is greater than 10mm, to further ensure the stability of the support.

[0076] In one embodiment, a second limiting part 12 is provided on the fixed stove ear 1. When the movable stove ear 2 rotates to the second position, the movable stove ear 2 abuts against the second limiting part 12 to restrict the movable stove ear 2 from continuing to rotate in a direction away from the first position. At the same time, since the second support surface 212 extends from top to bottom in a direction towards the center line, the movable stove is restricted from flipping in a direction towards the first position under the pressure of the arc-shaped bottom pot 300. This allows the movable stove ear 2 to be stably maintained in the second position, improving the support stability and reliability of the arc-shaped bottom pot 300.

[0077] The second limiting part 12 is provided on the side of the fixed furnace ear 1 away from the center line, and when the fixed furnace ear 1 is rotated to the second position, the lower end of the support plate part 22 is supported by the second limiting part 12. This avoids the need to set up an additional structure that cooperates with the second limiting part 12, simplifies the structure, and improves the performance.

[0078] In one embodiment, both the first limiting part 11 and the second limiting part 12 are horizontally arranged planar structures. The second limiting part 12 is lower than the first limiting part 11, and the second limiting part 12 and the first limiting part 11 are connected by an arc surface, with the opening of the arc surface facing the connecting shaft 3. This helps to prevent the support plate part 22 from colliding with the fixed furnace ear 1 when the movable furnace ear 2 rotates.

[0079] The first limiting part 11 is connected to the side facing the center line with the avoidance part 13. The avoidance part 13 extends downward at an angle in the direction of the center line to avoid collision between the movable furnace ear 2 and the fixed furnace ear 1 when the movable furnace ear 2 flips inward, thereby improving the rotation reliability of the movable furnace ear 2.

[0080] It is worth noting that the annular base 200 can be a solid annular structure or a concentrating disk structure. The fixed furnace ear 1 can be welded to the annular base 200, or it can be connected to the annular base 200 by riveting or other methods that can achieve a stable connection. The specific structure of the annular base 200 and the connection structure of the fixed furnace ear 1 on the annular base 200 can be set with reference to the existing technology, which is not the focus of this utility model and will not be described in detail here.

[0081] This embodiment also provides a stove, including the aforementioned burner frame. By using the burner frame, the stability and safety of the stove can be improved.

[0082] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0083] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this 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.
