Description

Technical Field

[0001] This application relates to the field of kitchen appliances technology, and in particular to a combustion device and a gas stove. Background Technology

[0002] Gas stoves typically use a pot rack to support cookware. After placing the cookware on the pot rack, the user can start cooking by controlling the burner of the gas stove to ignite it.

[0003] Currently, to facilitate the assembly of the pot rack and burner, some gas stoves fix the bottom ring of the pot rack and the base of the burner together, with the pot rack and burner serving as the combustion device of the gas stove. The pot rack has multiple feet installed on the bottom ring, which are fixed to the bottom ring by welding. The feet are strong enough to support the cookware being cooked on them. Support sections are provided at the top of the feet to support the cookware, extending towards the center of the combustion device.

[0004] However, when users need to clean the combustion device, the support section can hinder the user from cleaning the top surface of the burner, making cleaning inconvenient. Utility Model Content

[0005] Based on this, this application provides a combustion device and a gas stove to solve the problem of inconvenient cleaning of the burner in related technologies.

[0006] In a first aspect, embodiments of this application provide a combustion device, including a burner and a pot frame surrounding the burner, the pot frame comprising:

[0007] The bottom ring has an upward-facing positioning groove;

[0008] The foot piece has positioning holes;

[0009] The rotating shaft passes through the side wall of the positioning groove and the positioning hole.

[0010] The positioning hole is larger than the size of the rotating shaft in the height direction of the foot piece, and the positioning hole has a lower limit surface facing the bottom of the foot piece; the foot piece can rotate between a support position and a clearance position. When the foot piece is in the support position, the bottom end of the foot piece abuts against the bottom wall of the positioning groove, and the lower limit surface disengages from the rotating shaft; when the foot piece is in the clearance position, the side wall of the rotating shaft abuts against the lower limit surface, the side of the foot piece away from the burner abuts against the wall of the positioning groove, and the projection of the foot piece in the vertical direction avoids the projection of the burner in the vertical direction.

[0011] In one possible implementation, the positioning groove has a first limiting wall and a second limiting wall disposed opposite to each other, the first limiting wall being located on the side of the positioning groove facing the burner, and the second limiting wall being located on the side of the positioning groove away from the burner.

[0012] When the foot piece is in the support position, the bottom end of the foot piece is located between the first limiting wall and the second limiting wall;

[0013] When the foot plate is in the avoidance position, the side of the foot plate away from the burner abuts against the top of the second limiting wall.

[0014] In one possible implementation, the bottom end of the foot piece is provided with an extension section, which extends into the positioning groove when the foot piece is in the support position.

[0015] Along the width direction of the foot piece, the size of the positioning groove is larger than the size of the extension section, and the size of the positioning hole is larger than the size of the rotating shaft.

[0016] In one possible implementation, the difference between the size of the positioning groove and the size of the extension section along the width direction of the foot piece is in the range of 0.6mm-2mm, and the difference between the size of the positioning hole and the size of the rotating shaft is greater than or equal to 0.6mm.

[0017] In one possible implementation, the bottom end of the extension is rounded on the side facing the burner.

[0018] In one possible implementation, the positioning hole has an upper limit surface facing the top of the foot piece, and when the foot piece is in the support position, there is a first gap between the upper limit surface and the pivot.

[0019] In one possible implementation, the first interval is greater than or equal to 0.5 mm.

[0020] In one possible implementation, the foot plate has a stepped portion on the side facing the burner, the stepped portion is located above the positioning groove, and the stepped portion is configured to abut against the bottom ring.

[0021] In one possible implementation, the burner includes a base and a flame cap mounted on the base, with a bottom ring surrounding the outside of the base and forming an integral part therewith.

[0022] Secondly, embodiments of this application provide a gas stove, including the combustion device described above.

[0023] The present application provides a combustion device and a gas stove. The combustion device includes a burner and a pot rack surrounding the burner. The pot rack includes a base ring, feet, and a rotating shaft. Positioning holes are provided on the feet. The rotating shaft passes through the positioning holes and the side walls of the positioning grooves on the feet. The feet can rotate between a support position and a clearance position. When the feet are in the support position, the bottom end of the feet abuts against the bottom wall of the positioning groove; when the feet are in the clearance position, the vertical projection of the feet avoids the vertical projection of the burner. When the user needs to clean the combustion device, the feet can be lifted so that the side wall of the rotating shaft abuts against the lower limit surface of the positioning hole, and the feet can be rotated from the support position to the clearance position. At this time, the feet will not obstruct the user's cleaning of the burner, facilitating cleaning. Before cooking, the user can return the feet from the clearance position to the support position to begin cooking. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[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, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0047] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0048] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0049] In existing technology, the feet of the pot rack are welded to the base ring, and the top of the feet can obstruct the user from cleaning the burner. In addition, at the connection between the feet and the base ring, the material sinks downward due to the welding process, forming a concave shape. When cleaning the pot rack, the user needs to reach into the concave shape with a cloth to wipe it, and there are sometimes burrs in the concave shape that can hurt the hand and cause scratches.

[0050] After repeated consideration and verification, the inventors discovered that if the foot piece is rotatably mounted on the bottom ring of the pot rack, when the burner of the combustion device needs to be cleaned, the foot piece can be rotated outwards without obstructing the top of the burner, making it convenient for the user to clean. Furthermore, there is no concave shape between the foot piece and the bottom ring due to welding, preventing users from being injured by burrs in the concave shape when cleaning the pot rack, thus improving the safety of the combustion device. A positioning groove is provided in the bottom ring of the pot rack; after the foot piece returns to its original position from the outside to the inside, the bottom wall of the positioning groove can support the bottom end of the foot piece, ensuring that the foot piece can reliably support the pot.

[0051] In view of this, the inventor designed a combustion device and a gas stove. This combustion device features an upward-opening positioning groove on the bottom ring of the pot rack and positioning holes on the feet. A rotating shaft passes through the side wall of the positioning groove and the positioning holes, allowing the feet to rotate relative to the bottom ring between a support position and a clearance position. The positioning hole is larger than the rotating shaft in the height direction of the feet. When the feet are in the support position, the bottom wall of the positioning groove abuts against the bottom of the feet, reliably supporting the feet. The end of the positioning hole facing the bottom of the feet disengages from the rotating shaft. The fit between the rotating shaft and the positioning hole, along with the positioning groove, limits the foot's position, ensuring reliable support for the pot. When the user needs to clean the burner, the feet can be rotated from the support position to the clearance position. In this position, the end of the foot facing the bottom of the positioning hole abuts against the side wall of the rotating shaft, and the side of the foot away from the burner abuts against the wall of the positioning groove. The feet do not obstruct the top of the burner, facilitating cleaning. At the same time, no concave shape will be formed between the foot piece and the bottom ring, avoiding burrs in the concave shape from injuring the user.

[0052] The technical solutions of the combustion device and gas stove provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 12 As shown, the combustion device provided in this application embodiment includes a burner 100 and a pot frame 200 surrounding the outside of the burner 100. The burner 100 and the pot frame 200 are fixedly connected, which facilitates the user to assemble the combustion device.

[0054] The pot holder 200 includes a base ring 210, foot pieces 220, and a rotating shaft 230. The base ring 210 is provided with an upward-opening positioning groove 211. The shape of the base ring 210 can be rectangular or square, or other suitable shapes, and is not limited to one shape here. Optionally, the positioning groove 211 can be integrally formed on the base ring 210.

[0055] The foot piece 220 has positioning holes 221. The number of foot pieces 220 can be multiple, such as three, four, or five, etc., and is not limited to a single number. The number of positioning grooves 211 on the bottom ring 210 is the same as the number of foot pieces 220, with the bottom end of each foot piece 220 extending into one positioning groove 211. In the thickness direction of the foot piece 220, the size of the foot piece 220 can match the size of the positioning groove 211, thereby restricting the foot piece 220 from moving along its own thickness direction, which helps to improve the support of the foot piece 220.

[0056] The rotating shaft 230 passes through the side wall of the positioning groove 211 and the positioning hole 221. The side wall of the positioning groove 211 has an assembly hole 212. After the bottom end of the foot piece 220 is placed into the corresponding positioning groove 211, a positioning pin or bolt can be used as the rotating shaft 230. By passing the rotating shaft 230 through the assembly hole 212 and the positioning hole 221, a portion of the foot piece 220 can be confined within the positioning groove 211, and the foot piece 220 can rotate relative to the bottom ring 210. Optionally, such as... Figure 8 and Figure 9 As shown, a shoulder 231 can be provided on the rotating shaft 230, which can abut against the outer side of the wall of the positioning groove 211 to limit the rotation of the rotating shaft 230.

[0057] The positioning hole 221 is larger than the dimension of the rotating shaft 230 in the height direction of the foot piece 220. The positioning hole 221 has a lower limiting surface 2211 facing the bottom end of the foot piece 220. Schematic, the positioning hole 221 on the foot piece 220 can be an oblong hole, with its length extending along the height direction of the foot piece 220. After the rotating shaft 230 passes through the side wall of the positioning groove 211 and the positioning hole 221, the foot piece 220 can slide relative to the rotating shaft 230 along the length direction of the oblong hole. The cooperation between the rotating shaft 230 and the positioning hole 221 can limit the foot piece 220 and restrict its rotation range. Schematic, the lower limiting surface 2211 is the bottom end surface of the positioning hole 221.

[0058] The foot piece 220 can rotate between a support position and a clearance position. When the foot piece 220 is in the support position, the bottom end of the foot piece 220 abuts against the bottom wall 2111 of the positioning groove 211, and the lower limit surface 2211 disengages from the rotating shaft 230. When the foot piece 220 is in the clearance position, the side wall of the rotating shaft 230 abuts against the lower limit surface 2211, and the side of the foot piece 220 away from the burner 100 abuts against the wall of the positioning groove 211. The projection of the foot piece 220 in the vertical direction avoids the projection of the burner 100 in the vertical direction.

[0059] It is worth mentioning that when the foot piece 220 is in the support position, the bottom wall 2111 of the positioning groove 211 can reliably support the foot piece 220, and the cooperation between the rotating shaft 230 and the positioning hole 221, as well as the positioning groove 211, can limit the foot piece 220, allowing it to reliably support the cookware. The rotation angle of the foot piece 220 can be limited by the wall of the positioning groove 211 and the rotating shaft 230. When the foot piece 220 is in the avoidance position, the projection of the foot piece 220 in the vertical direction does not coincide with the projection of the burner 100 in the vertical direction, and the bottom ring 210 is not obstructed by the foot piece 220 above the portion outside the positioning groove 211 and above the burner 100.

[0060] When the user needs to clean the combustion device, the user can gently pull the foot piece 220 of the pot holder 200 upwards. The height of the pull is limited by the positioning hole 221. When the lower limit surface 2211 of the positioning hole 221 abuts against the side wall of the rotating shaft 230, the top of the foot piece 220 can be rotated outwards, i.e., away from the burner 100. In this way, the foot piece 220 can be rotated from the support position to the avoidance position. When the user needs to reset the foot piece 220, the top of the foot piece 220 can be rotated inwards, i.e., towards the burner 100. After the foot piece 220 is rotated to a vertical position, the bottom of the foot piece 220 is placed downwards into the positioning groove 211, so that the bottom end of the foot piece 220 abuts against the bottom wall 2111 of the positioning groove 211, thus completing the reset of the foot piece 220.

[0061] The combustion device provided in this embodiment allows the user to lift the foot piece 220 when cleaning it, so that the side wall of the rotating shaft 230 abuts against the lower limit surface 2211 of the positioning hole 221. The foot piece 220 is then rotated from the supporting position to the clearance position, ensuring it does not obstruct the user's cleaning of the burner 100, thus facilitating cleaning. Before cooking, the user simply returns the foot piece 220 from the clearance position to the supporting position to begin cooking.

[0062] Furthermore, the foot piece 220 is not fixed to the base ring 210 by welding, and no concave shape is formed between the foot piece 220 and the base ring 210, so users will not be injured by burrs in the concave shape when cleaning the combustion device. At the same time, the combustion device does not need to set up elastic elements or other limiting components to limit the foot piece 220 in the support position or avoidance position. The limiting of the foot piece 220 will not fail due to excessive temperature of the combustion device, and the foot piece 220 can be reliably fixed in the support position or avoidance position.

[0063] Indicative, such as Figures 1-5 and Figures 10-12 As shown, the burner 100 includes a base 110 and a flame cap 120 mounted on the base 110, and a bottom ring 210 surrounds the outside of the base 110 and forms an integral part with the base 110.

[0064] Optionally, the burner cap 120 includes an inner ring burner cap and an outer ring burner cap surrounding the outer side of the inner ring burner cap, with the inner and outer ring burner caps respectively mounted on the base 110. By making the base ring 210 and the base 110 into a single piece, the operator does not need to lock and fix the base ring 210 and the base 110, which can improve the assembly efficiency of the combustion device.

[0065] In one embodiment, such as Figures 3-5As shown, the positioning groove 211 has a first limiting wall 2112 and a second limiting wall 2113 arranged opposite to each other. The first limiting wall 2112 is located on the side of the positioning groove 211 facing the burner 100, and the second limiting wall 2113 is located on the side of the positioning groove 211 away from the burner 100. Schematic, the first limiting wall 2112 and the second limiting wall 2113 extend vertically and are arranged parallel to each other.

[0066] When the foot piece 220 is in the support position, the bottom end of the foot piece 220 is located between the first limiting wall 2112 and the second limiting wall 2113. For example... Figure 4 As shown, when the foot piece 220 is in the support position, the position of the foot piece 220 can be restricted by the first limiting wall 2112 and the second limiting wall 2113 to prevent the foot piece 220 from getting too close to or too far away from the burner 100.

[0067] When the foot plate 220 is in the avoidance position, the side of the foot plate 220 facing away from the burner 100 abuts against the top of the second limiting wall 2113. For example... Figure 5 As shown, when the side of the foot piece 220 away from the burner 100 abuts against the top of the second limiting wall 2113, the foot piece 220 is in an inclined state. The inclination angle of the foot piece 220 in the avoidance position can be controlled by setting the height of the second limiting wall 2113. The above setting can limit the outward rotation angle of the foot piece 220, preventing the foot piece 220 from hitting the panel of the gas stove located below the combustion device when in the avoidance position. At the same time, the foot piece 220 is in an inclined state when in the avoidance position, making it easy for the user to return the foot piece 220 from the avoidance position to the support position.

[0068] When the user gently pulls the foot piece 220 upwards until the lower limit surface 2211 of the positioning hole 221 abuts against the side wall of the rotating shaft 230, the side of the foot piece 220 facing away from the burner 100 is higher than the second limiting wall 2113. The second limiting wall 2113 will not obstruct the user from rotating the foot piece 220 outwards, at which point the user can rotate the foot piece 220 outwards. When the user needs to return the foot piece 220 from the avoidance position to the support position, the foot piece 220 is rotated inwards until its side facing the burner 100 abuts against the first limiting wall 2112, after which the user can place the bottom of the foot piece 220 downwards into the positioning groove 211.

[0069] In other embodiments, the positioning groove 211 may not have a second limiting wall 2113. When the foot piece 220 is in the avoidance position, the side of the foot piece 220 away from the burner 100 abuts against the bottom wall 2111 of the positioning groove 211, at which time the foot piece 220 is flat.

[0070] In one embodiment, such as Figures 3-7As shown, the bottom end of the foot piece 220 is provided with an extension section 222. When the foot piece 220 is in the support position, the extension section 222 extends into the positioning groove 211. For example, the extension section 222 extends along the height direction of the foot piece 220. When the foot piece 220 is in the support position, the bottom end of the extension section 222 abuts against the bottom wall 2111 of the positioning groove 211. After the extension section 222 extends into the positioning groove 211, the first limiting wall 2112 and the second limiting wall 2113 in the positioning groove 211 can restrict the position of the extension section 222, preventing the foot piece 220 from getting too close to or too far away from the burner 100.

[0071] Along the width direction of the foot piece 220, the size of the positioning groove 211 is larger than the size of the extension section 222, and the size of the positioning hole 221 is larger than the size of the rotating shaft 230. The above arrangement allows the foot piece 220 to wobble relative to the bottom ring 210 after it is in the supported position.

[0072] In related technologies, after the multiple feet 220 of the pot rack 200 are welded to the base ring 210, the apexes of the multiple feet 220 are generally not located on the same horizontal plane, and there is an angular deviation of less than 3° between the height direction and the vertical direction of the feet 220. When the cookware (especially pointed-bottom cookware) is placed on the pot rack 200, the pot rack 200 generally only has three feet 220 reliably supporting the cookware, causing the other feet 220 to not touch the cookware, and the positions of the cookware and the other feet 220 to be suspended in the air. During the cooking process, the cookware is prone to shaking, and in severe cases, it may cause the cookware to be placed off-center, causing it to fall, affecting the user experience.

[0073] In this embodiment, the multiple feet 220 of the pot holder 200 are all positioned in the support position. When the pot is placed on the combustion device, and the pot contacts three feet 220, those three feet 220 can sway and tilt inward, allowing the remaining feet 220 to also contact the pot. When the user is cooking, the feet 220 can sway freely as the pot slides back and forth, but the extensions 222 of the feet 220 will not disengage from the positioning grooves 211 of the base ring 210. Thus, the multiple feet 220 of the combustion device can reliably support the pot, ensuring its stability. Furthermore, the multiple feet 220 of the combustion device can adaptively conform to the pot to accommodate different placement angles, improving the user experience.

[0074] In one specific embodiment, along the width direction of the foot piece 220, the difference between the size of the positioning groove 211 and the size of the extension 222 is in the range of 0.6mm-2mm, and the difference between the size of the positioning hole 221 and the size of the rotating shaft 230 is greater than or equal to 0.6mm.

[0075] For example, when the foot piece 220 is in the supporting position, there is a gap of 0.3mm-1mm between one side of the foot piece 220 and the wall of the positioning groove 211 along the width direction of the foot piece 220. For example, the difference between the size of the positioning groove 211 and the size of the extension section 222 can be 0.6mm, 1.2mm, 1.5mm, 1.8mm, or 2mm, etc., and is not limited to a single value. When the difference between the size of the positioning groove 211 and the size of the extension section 222 is less than 0.6mm, the inward tilt of the foot piece 220 after being in the supporting position is too small, and some of the foot pieces 220 may fail to support the pot; when the difference between the size of the positioning groove 211 and the size of the extension section 222 is greater than 2mm, the inward tilt of the foot piece 220 after being in the supporting position is too large, and multiple foot pieces 220 of the combustion device may tilt inward even after supporting the pot, affecting the reliability of the combustion device in supporting the pot. The above configuration ensures that after the foot piece 220 that first contacts the cookware tilts inward, the remaining foot pieces 220 can reliably contact the cookware, and the multiple foot pieces 220 of the combustion device can reliably support the cookware.

[0076] Schematic illustration: After the pivot 230 passes through the positioning hole 221, there is a gap of not less than 0.3 mm between one side of the pivot 230 and the wall of the positioning hole 221 along the width direction of the foot piece 220. This arrangement ensures that the pivot 230 does not obstruct the inward tilting of the foot piece 220 after it is in the supported position.

[0077] In one possible implementation, such as Figures 3-7 As shown, the bottom end of the extension 222 is rounded 2221 on the side facing the burner 100.

[0078] Specifically, the bottom end of the extension section 222 forms an arc-shaped wall on the side facing the burner 100, and the cross-section of this arc-shaped wall is a rounded corner 2221. Those skilled in the art can set the radius of the rounded corner 2221 as needed, and there is no unique limitation here.

[0079] When the foot piece 220 rotates from the supporting position to the avoidance position, the rounded corner 2221 at the bottom of the extension 222 can prevent interference between the extension 222 and the first limiting wall 2112. When the foot piece 220 is in the supporting position, the rounded corner 2221 at the bottom of the extension 222 facilitates the foot piece 220 to tilt inward, thereby making it easier for the multiple feet piece 220 of the combustion device to reliably support the pot.

[0080] In one embodiment, such as Figure 4 , Figure 6 and Figure 7 As shown, the positioning hole 221 has an upper limit surface 2212 facing the top of the foot piece 220. When the foot piece 220 is in the support position, there is a first gap between the upper limit surface 2212 and the rotating shaft 230.

[0081] The upper limit surface 2212 is the top surface of the positioning hole 221, which is opposite to the lower limit surface 2211. The first gap ensures that when the foot piece 220 is in the support position, only the bottom wall 2111 of the positioning groove 211 supports the foot piece 220, and the rotating shaft 230 is not subjected to the weight of the foot piece 220. During cooking, the rotating shaft 230 will not be impacted by the cookware. The above arrangement ensures that the rotating shaft 230 is not subjected to external forces when the foot piece 220 is in the support position, thus guaranteeing the reliability of the combustion device.

[0082] In one specific embodiment, the first interval is greater than or equal to 0.5 mm.

[0083] That is to say, when the foot piece 220 is in the support position, the first gap between the upper limit surface 2212 of the positioning hole 221 and the rotating shaft 230 is not less than 0.5mm. For example, the first gap can be 0.5mm, 0.8mm or 1mm, etc., and is not limited to one specific type.

[0084] The above configuration ensures that when the foot piece 220 is in the support position, the upper limit surface 2212 of the positioning hole 221 will not come into contact with the rotating shaft 230 due to assembly tolerances, thus ensuring the reliability of the combustion device.

[0085] like Figures 4-7 As shown, the foot piece 220 has a stepped portion 223 on the side facing the burner 100. The stepped portion 223 is located above the positioning groove 211 and is configured to abut against the bottom ring 210.

[0086] Schematic, the width of the extension 222 of the foot piece 220 is less than the width of the main body, and the step portion 223 is located between the main body and the extension 222 of the foot piece 220. When the foot piece 220 is in the supported position, the step portion 223 extends beyond the positioning groove 211, and the step portion 223 can abut against the top surface of the bottom ring 210.

[0087] With this structure, when the foot piece 220 is in the support position, after the stepped portion 223 of the foot piece 220 abuts against the bottom ring 210, the bottom ring 210 can further support the foot piece 220, thereby further improving the reliability of the combustion device in supporting the cookware.

[0088] This application also provides a gas stove, including the combustion device described above. Exemplarily, the combustion device can be placed on the panel of the gas stove.

[0089] The gas stove provided in this application uses the aforementioned combustion device, which allows users to easily clean the combustion device by rotating the foot plate 220, resulting in a superior user experience.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
