Description

Technical Field

[0001] This application relates to the field of cooking utensil technology, and more particularly to a cooking utensil. Background Technology

[0002] Many cooking appliances, such as microwave ovens, ovens, and air fryers, have a rotating rack inside. This rack can rotate stably around the central axis of the appliance. The rack is also equipped with a turntable. When food is placed on the turntable, it will rotate with the rack, resulting in more even cooking.

[0003] Existing turntables lack sufficient fixing force in actual use, and are prone to deviating from their normal position with slight external interference. Once the turntable deviates, its edges will continuously scrape against the side wall of the cooking utensil, producing a harsh friction sound; at the same time, the containers placed on the turntable will repeatedly hit the side wall along the turntable's deviation trajectory, producing a "clattering" noise, which not only affects the user experience but may also cause food to splatter; long-term deviation will also accelerate the wear and tear between the turntable and the side wall of the cooking utensil, shortening the lifespan of the cooking utensil. Utility Model Content

[0004] This application provides a cooking appliance designed to solve the technical problem that the turntable of the cooking appliance is prone to deviating from its normal position during rotation.

[0005] To achieve the above objectives, this application provides a cooking utensil, the cooking utensil comprising:

[0006] The body of the appliance;

[0007] A rotating frame, disposed within the appliance body and rotatably connected to the bottom inner wall of the appliance body; and

[0008] A turntable is disposed within the body of the appliance. The bottom surface of the turntable is recessed upward to form an annular groove. The annular groove connects to the rotating frame. The outer wall of the annular groove extends downward to form a stop. The vertical distance between the stop and the bottom inner wall of the appliance body is a. The vertical length of the portion of the rotating frame located within the annular groove is B. The ratio of B to a is 10 to 20.

[0009] Optionally, 'a' is 1.4 to 1.7 mm.

[0010] Optionally, the vertical distance between the stop and the bottom of the annular groove is C, and the ratio of C to B is 0.7 to 0.95. The stop is used to prevent the annular groove from separating from the rotating frame.

[0011] Optionally, the number of the stop members is one, and the stop member is in the shape of a ring plate.

[0012] Optionally, there are multiple stops, each stop being arc-shaped and arranged circumferentially along the annular groove. The horizontal distance between any two adjacent stops is less than the horizontal width of the rotating frame.

[0013] Optionally, the stop member is arranged to taper downwards.

[0014] Optionally, the horizontal width of the stop member is 8 to 15 mm.

[0015] Optionally, the turntable includes an integrally formed body and a peripheral portion, the peripheral portion being fitted outside the body, the thickness of the peripheral portion being less than the thickness of the body, the annular groove being formed on the portion of the body near the peripheral portion, and the stop being located at the connection between the peripheral portion and the body.

[0016] Optionally, the top surface of the body is recessed downwards, and the portion of the body opposite the stop member has the greatest variation.

[0017] Optionally, the outer wall of the annular groove is chamfered to the bottom of the annular groove, and the inner wall of the annular groove is chamfered to the bottom of the annular groove.

[0018] In this cooking appliance, the ratio of B to a is 10-20. The appliance uses a sufficiently long guide section (large B) and a sufficiently small offset gap (small a) to create a double constraint on the turntable, suppressing turntable misalignment at its source. The long guide section (large B) allows the rotating frame to form a long vertical contact surface with the inner wall of the annular groove, making it difficult for the turntable to tilt at its base during rotation, thus preventing eccentric rotation. a is the gap between the stop and the bottom inner wall of the appliance body, and also the maximum allowable value for turntable misalignment. a is strictly controlled within a small range. If the turntable misaligns due to accidental force, as long as the vertical movement reaches a, the stop will contact the bottom inner wall of the appliance body, physically limiting the turntable and directly preventing further misalignment. Furthermore, the turntable structure in this cooking appliance is simple, allowing factories to manufacture it without purchasing special equipment, resulting in low production costs.

[0033] This application provides a cooking appliance, which can be a microwave oven, oven, air fryer, etc. The cooking appliance includes an appliance body, a rotating rack, and a turntable. The rotating rack is disposed within the appliance body and rotatably connected to the inner bottom wall of the appliance body. The turntable is disposed within the appliance body, with an annular groove formed by an upward-facing recess on its bottom surface. The annular groove connects to the rotating rack, and a stop member extends downward from the outer wall of the annular groove. The vertical distance between the stop member and the inner bottom wall of the appliance body is 'a', and the vertical length of the portion of the rotating rack located within the annular groove is 'B', where the ratio of B to a is 10 to 20.

[0034] In this cooking appliance, the ratio of B to a is 10-20. The appliance uses a sufficiently long guide section (large B) and a sufficiently small offset gap (small a) to create a double constraint on the turntable, suppressing turntable misalignment at its source. The long guide section (large B) allows the rotating frame to form a long vertical contact surface with the inner wall of the annular groove, making it difficult for the turntable to tilt at its base during rotation, thus preventing eccentric rotation. a is the gap between the stop and the bottom inner wall of the appliance body, and also the maximum allowable value for turntable misalignment. a is strictly controlled within a small range. If the turntable misaligns due to accidental force, as long as the vertical movement reaches a, the stop will contact the bottom inner wall of the appliance body, physically limiting the turntable and directly preventing further misalignment. Furthermore, the turntable structure in this cooking appliance is simple, allowing factories to manufacture it without purchasing special equipment, resulting in low production costs.

[0035] Please combine Figures 1 to 5 The structure of cooking utensil 1 will be described in detail below.

[0036] The cooking appliance 1 of this application includes an appliance body 30, which is shaped like a container and is used to cook food or ingredients placed inside the appliance body 30. The cooking appliance 1 also includes a rotating rack 20, which is disposed within the appliance body 30 and rotates to connect with the bottom inner wall of the appliance body 30. In some embodiments, the rotating rack 20 includes a rack body and rollers 21 connected to each other. Multiple rollers 21 are arranged circumferentially along the rack body.

[0037] The cooking appliance 1 of this application includes a turntable 10, which is disposed within the appliance body 30. The bottom surface of the turntable 10 is recessed to form an annular groove 11, which is connected to a rotating frame 20. The rotating frame 20 drives the turntable 10 to rotate. In embodiments including rollers 21, the annular groove 11 connects to the rollers 21. The rollers 21 can significantly reduce frictional resistance, making the rotation of the turntable 10 smoother and quieter. Multiple circumferentially distributed rollers 21 can more stably support the turntable 10, preventing the turntable 10 from deforming or tilting due to gravity.

[0038] The outer wall and bottom of the annular groove 11 are chamfered, as are the inner wall and bottom of the annular groove 11. This chamfering design eliminates right-angle stress points through a rounded transition, evenly distributing external forces to the connection area between the groove wall and bottom of the annular groove 11. This significantly improves the turntable 10's resistance to deformation and durability, preventing cracking and damage caused by excessive local stress, and extending the overall lifespan of the turntable 10. The chamfered, inclined transition surface serves as a guide for positioning, facilitating the connection between the annular groove 11 and the rotating frame 20, thus improving daily usability. The rounded surface of the chamfer makes the contact between the rotating frame 20 and the groove wall of the annular groove 11 smoother, reducing wear and tear and ensuring stable rotation even after long-term operation. The smooth contact also reduces collision noise between the rotating frame 20 and the groove wall of the annular groove 11, enhancing the quietness of kitchen use. The chamfered design creates a smooth arc transition between the wall and bottom of the annular groove 11, eliminating cleaning dead angles such as right-angle gaps, making it easier for users to clean the turntable 10.

[0039] A stop 12 extends downward from the outer wall of the annular groove 11, meaning the stop 12 is integrally formed with the annular groove 11. The vertical distance (distance in the vertical direction) between the stop 12 and the bottom inner wall of the appliance body 30 is 'a', and the vertical length (length in the vertical direction) of the portion of the rotating frame 20 located within the annular groove 11 is 'B'. The ratio of B to a is 10 to 20. In the cooking appliance 1 of this application, the ratio of B to a is equal to 10 to 20. Thus, the cooking appliance 1 of this application forms a double constraint on the turntable 10 through a sufficiently long guide section (large B) and a sufficiently small offset gap (small a), suppressing the offset of the turntable 10 from the source. The long guide section (large B) allows the rotating frame 20 to form a long vertical contact surface with the inner wall of the annular groove 11, making it difficult for the turntable 10 to tilt at the root when rotating, thus preventing the turntable 10 from rotating eccentrically from the source. 'a' represents the gap between the stop 12 and the inner bottom wall of the appliance body 30, and is also the maximum allowable value for the offset of the turntable 10. 'a' is strictly controlled within a small range. If the turntable 10 is offset due to accidental force, as long as the vertical movement reaches 'a', the stop 12 will contact the inner bottom wall of the appliance body 30. The inner bottom wall of the appliance body 30 will physically limit the turntable 10, directly preventing it from continuing to move. Furthermore, the turntable 10 in the cooking appliance 1 of this application has a simple structure, and factories can manufacture it without purchasing special equipment, resulting in low production costs. Further, the ratio of B to 'a' can be approximately 10–15, 11–12, 12–13, 14–16, 13–15, 12–15, or 13–14, etc.

[0040] In some embodiments, 'a' is 1.4–1.7 mm. This 1.4–1.7 mm difference provides a small vertical buffer space for the rotating frame 20, allowing for minor dimensional deformations due to temperature changes (such as thermal expansion and contraction during cooking). The stop 12 also provides a constraint, ensuring the annular groove 11 remains connected to the rotating frame 20, preventing separation even during high-frequency vibrations of the cooking appliance 1. Furthermore, this distance range ensures the stop 12 does not contact the inner bottom wall of the appliance body 30 during rotation and provides additional lateral constraint. If the turntable 10 tends to shift due to extreme conditions, the stop 12 will approach the inner bottom wall of the appliance body 30 before the turntable 10, using the 1.4–1.7 mm gap to buffer the impact and prevent the turntable 10 from directly impacting the inner bottom wall of the appliance body 30, further protecting the turntable 10 and reducing wear. Furthermore, 'a' can be 1.5–1.7 mm, 1.55–1.65 mm, 1.58–1.62 mm, 1.5–1.65 mm, or 1.65–1.7 mm, etc.

[0041] The stop 12 is used to prevent the annular groove 11 from detaching from the rotating frame 20. The vertical distance (distance in the vertical direction) between the stop 12 and the bottom of the annular groove 11 is C, and the vertical length of the portion of the rotating frame 20 located within the annular groove 11 is B (as described above). The ratio of C to B is 0.7 to 0.95. The stop 12 is used to prevent the annular groove 11 from detaching from the rotating frame 20. The aforementioned ratio of 0.7 to 0.95 allows the stop 12 to prevent the annular groove 11 from detaching from the rotating frame 20 while retaining the small amount of movement space required by the rotating frame 20, ensuring that the turntable 10 does not deviate when rotating with the rotating frame 20 and can maintain smooth rotation. Furthermore, the ratio of 0.7 to 0.95 ensures the anti-detachment effect without excessively increasing the assembly difficulty of the turntable 10 and the rotating frame 20, avoiding the problem of difficult assembly and disassembly due to an excessively high stop. Furthermore, the ratio of C to B includes, but is not limited to, 0.75–0.95, 0.85–0.9, 0.75–0.9, 0.87–0.93, 0.89–0.91, 0.9–0.92, 0.93–0.94, or 0.91–0.93.

[0042] The sum of C and a may or may not equal B. The magnitude of their comparison depends on the height difference between the parts of the appliance body 30 connecting the stop 12 and the rotating frame 20 (located within the annular groove 11), and this application does not specifically limit this. For example, when the bottom inner wall of the appliance body 30 is a plane, the sum of C and a equals B; when the bottom inner wall of the appliance body 30 is a curved surface with the center convex upwards, the sum of C and a is greater than B; when the bottom inner wall of the appliance body 30 is a curved surface with the center concave downwards, the sum of C and a is less than B.

[0043] The turntable 10 includes an integrally formed body portion 13 and a peripheral portion 14. The peripheral portion 14 is fitted over the body portion 13, and its thickness is less than that of the body portion 13. An annular groove 11 is formed in the portion of the body portion 13 near the peripheral portion 14. A stop member 12 is located at the connection between the peripheral portion 14 and the body portion 13. The portion of the body portion 13 near the peripheral portion 14 maintains a relatively thicker dimension, ensuring that the annular groove 11 has sufficient structural strength and preventing insufficient depth of the annular groove 11 due to an excessively thin body portion 13. The stop member 12, located at the connection, can provide stable support with the help of the thick structure of the body portion 13, thereby enabling it to function better.

[0044] The top surface of the main body 13 is concave downwards, and the portion of the main body 13 opposite the stop member 12 exhibits the greatest variation. This concave design of the top surface of the main body 13 guides the container holding food or ingredients to automatically adjust to the center position of the turntable 10. This design ensures that the core limiting area of ​​the concave main body 13 precisely corresponds to the support range of the stop member 12. When the container is placed, the turntable 10 can stably support the weight thanks to the rigid connection (one-piece structure) between the stop member 12 and the main body 13. Simultaneously, the downward-facing concavity of the top surface of the main body 13 exerts a slight centripetal constraint force on the container. This design ensures that the centripetal constraint area of ​​the concave portion precisely corresponds to the lateral anti-slip range of the stop member 12. When the container on the turntable 10 tends to slide, the stop member 12 can simultaneously restrict the lateral movement of the annular groove 11 relative to the rotating frame 20, thereby preventing the turntable 10 from deviating.

[0045] like Figures 1 to 3 As shown, in some embodiments, there is one stop 12, which is in the shape of a ring plate. In other embodiments, there are multiple stop 12s, which are in the shape of arc-shaped blocks, and the multiple stop 12s are arranged circumferentially along the annular groove 11, with the horizontal distance between any two adjacent stop 12s being less than the horizontal width of the rotating frame 20. All of the above embodiments can achieve the function of preventing the stop 12 from separating from the annular groove 11 and the rotating frame 20.

[0046] The stop 12 is tapered downwards, meaning its lateral dimensions gradually decrease from top to bottom. This tapering slope of the stop 12 serves as a guide during assembly of the turntable 10 and the rotating frame 20. When the user places the turntable 10 onto the rotating frame 20, the annular groove 11 of the turntable 10 does not need to be perfectly aligned with the rotating frame 20. The top of the rotating frame 20 will first contact the slope of the stop 12, and the turntable 10 will naturally slide towards the rotating frame 20 via the slope. Simultaneously, the slope reduces friction between the rotating frame 20 and the stop 12 during disassembly, allowing the user to easily separate the turntable 10 by lifting it upwards. When the turntable 10 is subjected to external forces (such as slight impacts when the user places a container, or vibrations during handling of the cooking utensil 1), the rotating frame 20 may exert lateral or vertical impact forces on the stop 12. The slope disperses these impact forces along the slope, buffering the lateral impact force of the rotating frame 20 and reducing localized wear on the stop 12.

[0047] The horizontal width of the stop 12 is 8–15 mm. This width ensures sufficient bearing area at the top of the stop 12, allowing for even stress transfer to the main body 13 (a rigid, one-piece molded structure) when impacted by the rotating frame 20, preventing root cracking. It also controls material usage, combining the lightweight advantages of the tapered design with "anti-detachment rigidity" and "lightweight operation." Furthermore, the horizontal width of the stop 12 can be 8–14 mm, 10–14 mm, 11–12 mm, 8–10 mm, 9–12 mm, or 10–12 mm, etc.

[0048] The above embodiments are only used to illustrate the present application and are not intended to limit it. Although the present 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included within the protection scope of the present application.
