Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a stove head structure and stove. Background Technology

[0002] Currently, the water tray of gas stoves on the market is matched with the burner grates. Generally, the water tray has adjustment grooves that match the support legs of the burner grates to ensure proper installation of the water tray and the burner grates, thereby ensuring that the burner grates and burners are coaxial and preventing the burner grates from rotating easily.

[0003] However, due to the diverse burner hole layouts of gas stoves on the market, the burner supports vary, leading to different installation angles for different supports. Consequently, the shapes and sizes of the water trays that mate with the burner supports are also diverse, making standardization difficult. Furthermore, because the installation method of the burner support relative to the water tray is relatively simple, and their relative positions are also relatively fixed, current water trays do not contribute to adjusting the product's energy efficiency.

[0004] Therefore, there is an urgent need for a new stove structure and stove appliance to solve the above problems. Utility Model Content

[0005] One of the technical problems solved by this utility model is to provide a stove head structure that can effectively solve the problems of poor water pan versatility and fixed stove rack installation position, with better versatility and adjustable stove rack installation position.

[0006] The second technical problem solved by this utility model is to provide a stove that can effectively solve the problem of single energy efficiency and is applicable to more scenarios.

Each lower support foot can be placed on any of the bearing surfaces of the corresponding adjustment structure, and all the lower support feet are supported on the bearing surfaces of the same height.

[0011] The stove head structure described in this utility model has the following advantages compared with the prior art:

[0012] This invention features a stove frame with multiple lower support legs extending beyond the lower surface of the stove frame to engage with a water tray, thus connecting the stove frame and the water tray. Specifically, the water tray has adjustment structures corresponding to the lower support legs, each with multiple bearing surfaces of different heights. This allows the stove frame to have different heights when a lower support leg is positioned on one of these bearing surfaces. This adapts to different stove frames, improving the versatility of the burner structure, and also allows for different installation heights to accommodate different burner holes with varying energy efficiencies. It is understood that different installation heights of the stove frame correspond to different energy efficiencies in the cooktop. Therefore, this burner structure also greatly facilitates the overall performance debugging during product development, avoiding the cumbersome work of adding shims or lowering the stove frame height, thus improving debugging efficiency and shortening the product development cycle.

The transition portion includes a transition surface and a connecting surface. The first end of the transition surface is connected to the lowest bearing surface, and the second end extends upward at an angle toward the highest bearing surface. The connecting surface connects the second end of the transition surface and the highest bearing surface of the adjacent adjustment structure.

[0018] In one embodiment, the bearing surface is arranged parallel to the horizontal plane, or the bearing surface is set as an arc surface.

[0019] In one embodiment, the water tray has a rotating limiting annular surface with its axis vertically arranged. The lower support foot rotates in conjunction with the rotating limiting annular surface to allow the lower support foot to rotate from one of the bearing surfaces to an adjacent bearing surface.

[0020] In one embodiment, the water tray has a boss portion, the outer wall of the boss portion forms the rotation limiting annular surface, the adjustment structure is disposed around the outer side of the boss portion, and the inner side of the adjustment structure is connected to the rotation limiting annular surface.

[0021] In one embodiment, the lower support foot has a rotating inner limiting surface and a lower support limiting surface arranged at an angle, the rotating inner limiting surface rotatably engaging with the outer side wall of the boss portion; the lower support limiting surface can abut against the upper end of the boss portion.

[0022] In one embodiment, the water tray is provided with a protruding ring portion, the upper side of the protruding ring portion is provided with the adjustment structure, and the outer side wall of the protruding ring portion forms the rotation limiting ring surface;

[0023] The lower support foot has a support surface and a rotation limiting surface connected at an angle. The support surface is supported on the bearing surface, and the rotation limiting surface is rotatably engaged with the rotation limiting ring surface.

[0024] The second technical problem mentioned above is solved by the following technical solution:

[0025] A cooktop includes the burner structure as described in any of the above embodiments.

Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] 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 technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] like Figures 1-10 As shown, this embodiment provides a stove head structure, which includes a stove frame 100 and a water pan 200. The stove frame 100 is provided with a plurality of lower support legs 110, which extend out of the lower surface of the stove frame 100. The water pan 200 is provided with an adjustment structure 210 corresponding to each of the lower support legs 110. The adjustment structure 210 has a plurality of bearing surfaces 2111 with different heights. The plurality of bearing surfaces 2111 are spaced apart along the circumference of the water pan 200. Each lower support leg 110 can be placed on any bearing surface 2111 of the corresponding adjustment structure 210, and all lower support legs 110 are supported on the bearing surface 2111 at the same height.

[0047] The burner frame 100 is configured with multiple lower support legs 110, which extend beyond the lower surface of the burner frame 100 to engage with the water tray 200, thus connecting the burner frame 100 and the water tray 200. Specifically, the water tray 200 is equipped with adjustment structures 210 corresponding to each lower support leg 110. Each adjustment structure 210 has multiple bearing surfaces 2111 with different heights. Therefore, when a lower support leg 110 is placed on one of the bearing surfaces 2111, the burner frame 100 can have different heights. This allows for adaptation to different burner frames 100, improving the versatility of the burner structure; it also allows for different installation heights of the burner frame 100, thus adapting to different burner holes for different energy efficiencies. It is understood that different installation heights of the burner frame 100 correspond to different energy efficiencies of the cooktop. Therefore, the above-mentioned burner structure also greatly facilitates the overall performance debugging during the product development stage, avoiding the complicated and troublesome work of adding shims or lowering the height of the burner frame 100, improving debugging efficiency and shortening the product development cycle.

[0048] Specifically, such as Figures 1-3 As shown, the water pan 200 is provided with a protruding part 230, and a through hole 231 is provided in the center of the protruding part 230 for adapting to the burner, igniter and other structures of the stove. The adjustment structure 210 is arranged circumferentially to accommodate the protruding part 230. The stove frame 100 is also provided with upper support feet 120 for supporting the pot. It can be understood that when the stove frame 100 and the water pan 200 have different installation heights, the distance between the bottom of the boiler and the burner will also be different, resulting in different heating effects on the pot and thus different energy efficiencies. For example, the stove frame 100 is provided with four lower support feet 110, which are evenly spaced apart. Therefore, the water pan 200 has four evenly spaced adjustment structures 210 arranged circumferentially.

[0049] In this embodiment, a transition portion 211 is provided between adjacent bearing surfaces 2111. By providing the transition portion 211, the lower support foot 110 can slide along the transition portion 211 to realize the conversion from the lower bearing surface to the higher bearing surface in two adjacent bearing surfaces 2111.

[0050] Specifically, the transition section 211 includes a transition surface 2112 and a connecting surface 2113. The first end of the transition surface 2112 is connected to the lower bearing surface. The transition surface 2112 is inclined relative to the horizontal plane so that the second end of the transition surface 2112 extends upward in a direction toward the higher bearing surface. The connecting surface 2113 connects the second end of the transition surface 2112 and the higher bearing surface. The inclined transition surface 2112 allows the lower support leg 110 of the furnace frame 100 to slide along the transition surface 2112 when the operator adjusts the installation height of the furnace frame 100 relative to the water pan 200 by rotating the furnace frame 100, thus making the adjustment process more effortless.

[0051] Furthermore, a transition section 211 is provided between the highest bearing surface of the adjustment structure 210 and the lowest bearing surface of the adjacent adjustment structure 210. By also providing a transition section 211 between the first and last bearing surfaces 2111 of the adjacent adjustment structures 210, multiple adjustment structures 210 are connected to form a continuous ring structure, thereby improving the continuity of the furnace frame 100 adjustment.

[0052] It is understood that the transition portion 211 between adjacent bearing surfaces 2111 has the same structure as the transition portion 211 between the highest bearing surface of the adjustment structure 210 and the lowest bearing surface of the adjacent adjustment structure 210. Therefore, the transition portion 211 provided between the highest bearing surface of the adjustment structure 210 and the lowest bearing surface of the adjacent adjustment structure 210 also includes a transition surface 2112 and a connecting surface 2113. The first end of the transition surface 2112 is connected to the lowest bearing surface, and the second end extends upward at an angle toward the highest bearing surface. The connecting surface 2113 connects the second end of the transition surface 2112 and the highest bearing surface in the adjacent adjustment structure 210.

[0053] Optionally, a limiting part is provided on the connecting surface 2113, which can abut against the lower support foot 110 to limit the lower support foot 110. For example, the connecting surface 2113 is arranged perpendicular to the horizontal plane. When the connecting surface 2113 is vertical, it can prevent the water pan 200 from rotating in the opposite direction of the adjustment direction under external force, improving the reliability of the furnace frame 100 installed on the water pan 200.

[0054] In other embodiments, such as Figure 4 As shown, the connecting surface 2113 can also be inclined. When the connecting surface 2113 is inclined into a slope shape, the furnace frame 100 can slide along the connecting surface 2113 under the action of external force and then switch to a higher bearing surface, avoiding noise or even damage caused by the vertical fall of the furnace frame 100. Alternatively, a limiting part can be provided on the inclined connecting surface 2113, which can also reliably limit the lower support foot 110.

[0055] It is worth noting that the four sets of adjustment structures 210 are connected by the transition section 211, which improves the continuity of adjustment. Especially when the connecting surface 2113 is tilted, the furnace frame 100 can be rotated to match different adjustment structures 210. Furthermore, the length of the bearing surface 2111 along the circumference of the water pan 200 is adapted to the thickness of the lower support foot 110, meaning the bearing surface 2111 has a suitable width. This ensures reliable support for the lower support foot 110 while also guaranteeing its stability on the bearing surface 2111. Preferably, a buffer pad can also be fitted onto the lower support foot 110, which not only prevents wear between the lower support foot 110 and the adjustment structure 210 but also reduces noise during adjustment.

[0056] Preferably, transition fillets are provided between the bearing surface 2111 and the transition surface 2112, and between the transition surface 2112 and the connecting surface 2113. The provision of transition fillets helps to improve the smoothness of rotation when the furnace frame 100 is adjusted in height.

[0057] In this embodiment, the bearing surface 2111 is arranged parallel to the horizontal plane to improve the reliability of the bearing surface 2111 in bearing the lower support foot 110. Alternatively, the bearing surface 2111 can be set as an arc surface, which can also achieve the bearing of the lower support foot 110. Those skilled in the art can set the bearing surface 2111 according to actual needs, as long as it can be ensured that the bearing surface 2111 can abut against the lower support foot 110 in the vertical direction, and no specific limitation is made here.

[0058] Furthermore, in the same adjustment structure 210, the height of all bearing surfaces 2111 varies in steps along the circumference of the water pan 200. This ensures the consistency of height change when the rotating furnace frame 100 is adjusted, which helps to improve adjustment efficiency.

[0059] For example, each adjustment structure 210 is provided with six bearing surfaces 2111, the height of the six bearing surfaces 2111 increasing sequentially in a counterclockwise direction. Figure 1 As shown, the furnace frame 100 is positioned on the lowest bearing surface of the adjusting structure 210. When the furnace frame 100 is rotated counterclockwise, the lower support leg 110 and upper support leg 120 of the furnace frame 100 also rotate accordingly, and the height of the furnace frame 100 gradually increases to accommodate the flameout hole requirements of different burners. Simultaneously, the position of the furnace frame 100 will become increasingly higher, increasing the distance between the upper support leg 120 of the furnace frame 100 and the flameout hole of the burner, thus reducing energy efficiency.

[0060] In other embodiments, the height of the six bearing surfaces 2111 of each adjustment structure 210 decreases sequentially in a counterclockwise direction, such as... Figure 5 As shown, the furnace frame 100 is positioned on the highest bearing surface of the adjusting structure 210. When the furnace frame 100 is rotated counterclockwise, the lower support leg 110 and upper support leg 120 of the furnace frame 100 also rotate accordingly, and the height of the furnace frame 100 gradually decreases to accommodate the flameout requirements of different burners. Simultaneously, the position of the furnace frame 100 becomes increasingly lower, reducing the distance between the upper support leg 120 of the furnace frame 100 and the flameout of the burner, thus increasing energy efficiency.

[0061] Specifically, the water pan 200 has a rotating limiting annular surface with its axis vertically positioned. The lower support foot 110 rotates in conjunction with the rotating limiting annular surface. This rotating limiting annular surface allows the furnace frame 100 to rotate coaxially relative to the water pan 200, improving the reliability of adjustment and ensuring that the lower support foot 110 can smoothly and stably rotate from one bearing surface 2111 to an adjacent bearing surface 2111. It can be understood that the rotating limiting annular surface serves both as a radial positioning surface of the furnace frame 100 and a guiding surface during its rotation.

[0062] As an optional solution for the stove head structure, such as Figure 6 and Figure 7 As shown, the adjustment structure 210 is arranged around the outer side of the boss portion 230, and the inner side of the adjustment structure 210 is connected to the rotation limiting annular surface. At this time, the outer wall of the boss portion 230 forms the rotation limiting annular surface.

[0063] For ease of description, the rotating limiting annular surface at this time is defined as the first rotating limiting annular surface 212. Correspondingly, the lower support foot 110 is provided with a rotating inner limiting surface 111, which can rotate and engage with the outer wall of the boss portion 230, i.e., the first rotating limiting annular surface 212. By providing the mutually engaging first rotating limiting annular surface 212 and rotating inner limiting surface 111, the coaxiality between the water pan 200 and the furnace frame 100 is ensured.

[0064] In summary, the stove frame 100 of the aforementioned stove structure is placed on the water tray 200. At this time, the lower support leg 110 cooperates with the adjustment structure 210, and the lower surface of the lower support leg 110 contacts one of the bearing surfaces 2111. Since both the connecting surface 2113 and the transition surface 2112 are higher than the bearing surface 2111, the stove frame 100 will remain on the bearing surface 2111 under its own weight and will not easily rotate. And since the inner rotation limiting surface 111 matches the first rotation limiting ring surface 212, the stove frame 100 and the water tray 200 are coaxial and will not deviate.

[0065] The adjustment process is as follows, such as Figure 6 As shown, when the furnace frame 100 is subjected to a clockwise force, guided by the first rotation limiting annular surface 212, the lower support leg 110 will rotate around the first rotation limiting annular surface 212. When the connecting surface 2113 contacts the lower support leg 110, since the connecting surface 2113 is vertical, the lower support leg 110 cannot continue to rotate clockwise, and therefore the furnace frame 100 stops rotating. Figure 7As shown, when the furnace frame 100 is subjected to a counterclockwise force, guided by the first rotation limiting annular surface 212, the lower support leg 110 will rotate around the first rotation limiting annular surface 212. After the lower surface of the lower support leg 110 leaves the bearing surface 2111, it enters the transition surface 2112. Since the transition surface 2112 is sloping, the furnace frame 100 moves upward while rotating. After the lower surface of the lower support leg 110 reaches the top of the transition surface 2112, it continues to rotate, leaves the transition surface 2112, and then passes through the connecting surface 2113 to reach the next bearing surface 2111. In the above manner, the furnace frame 100 can be rotated clockwise until it reaches the last bearing surface 2111. Since the bearing surfaces 2111 increase in height sequentially in the counterclockwise direction, the distance between the upper support leg 120 of the furnace frame 100 and the burner's flame hole increases each time the furnace frame 100 engages with a bearing surface 2111. Therefore, to achieve maximum energy efficiency, the lower support leg 110 should be positioned on the lowest bearing surface. However, at this position, the distance between the upper support leg 120 of the furnace frame 100 and the burner's flame holes is minimal, which may result in a larger volume of flue gas. If this exceeds the national standard requirements, the furnace frame 100 can be rotated counterclockwise to position the lower support leg 110 on a slightly higher bearing surface 2111, thus increasing the distance between the upper support leg 120 and the burner's flame holes. The above adjustment process is simple and convenient, and the structure and adjustment method greatly facilitate the overall performance debugging during the product development stage, avoiding the complicated and troublesome work of adding shims or lowering the height of the furnace frame 100.

[0066] In other embodiments, such as Figure 8 As shown, the lower support foot 110 is also provided with a lower support limiting surface 112, and the inner rotating limiting surface 111 and the lower support limiting surface 112 are set at an angle. The lower support limiting surface 112 can abut against the upper end of the boss portion 230. At this time, the lower support limiting surface 112 can abut against the boss portion 230, and the abutment is more reliable. It can be understood that when the lower support limiting surface 112 abuts against the upper edge of the first rotating limiting ring surface 212, the support of the furnace frame 100 by the boss portion 230 will affect the fit between the lower surface of the lower support foot 110 and the bearing surfaces 2111 of different heights. Therefore, it can be set so that when the lower surface of the lower support foot 110 fits against the lowest bearing surface 2111, the lower support limiting surface 112 can abut against the upper edge of the boss portion 230, so as to ensure the stability and reliability of the furnace frame 100 installation at this time, and at the same time, it will not cause the adjustable height range of the furnace frame 100 to decrease.

[0067] As an optional solution for the stove head structure, such as Figure 9 and Figure 10As shown, the water tray 200 has a protruding ring portion, and an adjustment structure 210 is provided on the upper side of the protruding ring portion. The outer wall of the protruding ring portion forms a rotation limiting ring surface. For ease of description, this rotation limiting ring surface is defined as the second rotation limiting ring surface 213. The lower support foot 110 cooperates with the second rotation limiting ring surface 213 to achieve positioning and rotation adjustment.

[0068] Furthermore, the lower support foot 110 is provided with a rotating outer limiting surface 113, which can rotate in conjunction with the outer peripheral wall of the water pan 200, i.e., the second rotating limiting annular surface 213. By providing the mutually cooperating second rotating limiting annular surface 213 and rotating outer limiting surface 113, the coaxiality between the water pan 200 and the furnace frame 100 is ensured. That is, the second rotating limiting annular surface 213 is both the radial positioning surface of the furnace frame 100 and the guide surface during the rotation of the furnace frame 100. At the same time, the lower support foot 110 is also provided with a support surface that is connected to the rotating outer limiting surface 113 at an angle, and the support surface is used to support the bearing surface 2111.

[0069] It is worth noting that in this scheme, the first rotation limiting ring surface 212 may not be provided, and the boss portion 230 may be set to be lower than the bearing surface 2111 and the transition portion 211. In this case, the inner side of the bearing surface 2111 and the transition portion 211 may be provided with an inner side surface 214 connected to the boss portion 230, so as to realize the connection between the bearing surface 2111, the transition portion 211 and the boss portion 230, and at the same time improve the structural strength of the adjustment structure 210.

[0070] Furthermore, the inner surface 214 can also serve as a rotation limiting ring surface. Correspondingly, a limiting surface that can rotate and cooperate with the inner surface 214 is provided on the lower support foot 110, which can also realize the rotation adjustment of the furnace frame 100.

[0071] Preferably, the water tray 200 is further provided with an outward flange 220, which is disposed circumferentially on the second rotation limiting annular surface 213 and extends along the horizontal plane. The outward flange 220 is spaced apart from the lower edge of the lower support foot 110. The outward flange 220 helps to improve the strength of the water tray 200 and avoids the problem of twisting and deformation of the water tray 200. It is worth noting that in the scheme where the lower support foot 110 is provided with a rotation limiting surface 113, the lower surface of the lower support foot 110 is spaced apart from the outward flange 220 to avoid the outward flange 220 affecting the height adjustment of the furnace frame 100.

[0072] This embodiment also discloses a cooktop, including the burner structure described in any of the above embodiments. The cooktop with the above-described burner structure allows for adjustable mounting height of the burner rack 100 to accommodate different energy efficiency tubes; it also adapts to different burner racks 100, offering better versatility; furthermore, the burner structure greatly facilitates the overall performance debugging process during product development, resulting in higher debugging efficiency, shorter product development cycles, and thus stronger market competitiveness.

[0073] 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.

[0074] 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.
