Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a cooking utensil. Background Technology

[0002] In recent years, with the development of smart homes and automated cooking technologies, automatic stir-fry machines, as a type of intelligent kitchen appliance, have gradually gained market attention. By simulating the actions and processes of manual stir-frying, automatic stir-fry machines can automate cooking operations, not only improving cooking efficiency but also providing users with a more convenient cooking experience. Their core functions include automatic stirring, precise temperature control, and timed cooking, meeting the diverse needs of users for food preparation, and are especially suitable for the busy pace of modern life.

[0003] In related technologies, the structure of a cooking machine typically includes a pot body and a lid, with the design of the lid being crucial for the sealing and ease of operation during the cooking process. Specifically, the lid usually consists of a first lid and a second lid. The first lid is foldable and positioned above the pot body, while the second lid covers the filling port of the first lid. This design allows users to add ingredients or seasonings to the pot by opening the second lid during cooking, offering the advantage of convenient operation.

[0004] However, in related technologies, the opening and closing of the first and second lids usually requires manual operation, resulting in a low degree of automation. Users need to frequently open or close the second lid manually during cooking, which increases the cumbersomeness of the operation and negatively impacts the user experience. Utility Model Content

[0005] This utility model provides a cooking appliance to solve the problem that the opening and closing of the first and second lids in related technologies usually requires manual operation and has a low degree of automation.

[0006] This utility model provides a cooking appliance, which includes: a pot body; a lid, including a first lid and a second lid, the first lid being closable and covering the pot opening, the first lid having a feeding port, and the second lid being closable and covering the feeding port; a driving component and a transmission mechanism, the driving component being drivenly connected to the first lid and the second lid respectively through the transmission mechanism, the driving component being able to drive the first lid and the second lid to open or close; wherein, the transmission ratio of the transmission mechanism is greater than or equal to 1:1.

[0007] Applying the technical solution of this utility model, the cooking appliance includes a pot body, a lid, a drive component, and a transmission mechanism. The drive component is driven to connect to the first lid and the second lid via the transmission mechanism, enabling the drive component to open or close the first and second lids. With this structure, the user does not need to manually open or close the first and second lids, increasing the automation level of the cooking appliance, simplifying user operation, and thus improving the user experience. Furthermore, since a single drive component can simultaneously open or close both lids (the first and second lids), the drive structure is simplified, reducing costs. Additionally, because the transmission ratio of the transmission mechanism is greater than or equal to 1:1, the drive component can transmit sufficiently large torque to the first and second lids, making the opening and closing process of the first and second lids more stable and effortless.

[0008] Furthermore, the transmission ratio of the transmission mechanism is between 1:1 and 3:1. In this way, the driving component can transmit a sufficiently large torque to both the first and second covers, while the cost and size of the transmission mechanism will not be too large.

[0009] Furthermore, the transmission mechanism includes: a driving transmission component rotatably mounted on the pot body, a driving component drivingly connected to the driving transmission component, and the driving transmission component having driving teeth; a first driven transmission component mounted on the first cover body, the first driven transmission component having first driven teeth capable of meshing with the driving teeth; and a second driven transmission component mounted on the second cover body, the second driven transmission component having second driven teeth capable of meshing with the driving teeth, wherein the number of teeth of both the first and second driven teeth is greater than or equal to the number of teeth of the driving teeth. Using the above structure, transmission is achieved through a gear structure, which has the advantages of simple and stable transmission structure.

[0010] Furthermore, the number of teeth of the driving tooth is n; the number of teeth of the first driven tooth is m, where m:n is between 1:1 and 10:1; and / or, the number of teeth of the second driven tooth is p, where p:n is between 1:1 and 10:1. Setting m:n between 1:1 and 10:1, and setting p:n between 1:1 and 10:1, makes the transmission ratio of the transmission mechanism between 1:1 and 10:1. In this way, the driving component can transmit a sufficiently large torque to the first and second covers, while the cost and size of the transmission mechanism are not too large.

[0011] Furthermore, the cooking appliance also includes a rotating shaft. Both the first and second lids are pivotally connected to the pot body via the rotating shaft. Multiple teeth of the first driven gear and multiple teeth of the second driven gear are arranged circumferentially around the rotating shaft. The distance D between the axis of the rotating shaft and the axis of the driving component is 5mm ≤ D ≤ 30mm. Setting the distance D between the axis of the rotating shaft and the axis of the driving component within the above range avoids both excessively small distances affecting gear machining and excessively large gears leading to large assembly space, thus affecting volume and assembly.

[0012] Furthermore, the module of the driving tooth, the first driven tooth, and the second driven tooth is all M, where 0.1 ≤ M ≤ 5. Setting the module M of the driving tooth, the first driven tooth, and the second driven tooth within the above range ensures that the cost is not too high due to an excessively low module, and that the rotation is not prone to jamming due to an excessively large module.

[0013] Furthermore, the active transmission component includes a drive shaft and a first gear and a second gear mounted on the drive shaft. The driving component is drivenly connected to the drive shaft. The first gear and the second gear are arranged axially along the drive shaft. The first gear has a driving tooth capable of meshing with a first driven tooth, and the second gear has a driving tooth capable of meshing with a second driven tooth. Both the first gear and the second gear are incomplete gears. When the drive shaft rotates, the first gear and the second gear alternately mesh with the corresponding driven transmission component. By setting the first gear and the second gear as incomplete gears, and utilizing the alternating meshing of the first gear and the second gear with the corresponding driven transmission component, the driving component can drive the first cover and the second cover to open or close sequentially via the transmission mechanism.

[0014] Furthermore, the first driven transmission component is a first arc-shaped rack extending around the rotation axis of the driving transmission component, with a first driven tooth disposed on the first arc-shaped rack; and / or, the second driven transmission component is a second arc-shaped rack extending around the rotation axis of the driving transmission component, with a second driven tooth disposed on the second arc-shaped rack. Both the first and second arc-shaped racks are arc-shaped structures. This structure, used in conjunction with the incomplete gears of the first and second gears, further simplifies the structure of the first and second driven transmission components and reduces costs, based on the premise that the driving component drives the first and second covers to open or close sequentially via the transmission mechanism.

[0015] Furthermore, the first lid's flipping angle is A1, where 0 < A1 ≤ 90°; and / or, the second lid's flipping angle is A2, where 0 < A2 ≤ 90°. If the first lid's flipping angle A1 is less than or equal to 0°, meaning the first lid does not flip, there will be interference when taking out or placing the inner pot; if the first lid's flipping angle A1 is greater than 90°, the active transmission component would rotate both lids more than 360°, which is not feasible. The second lid's flipping angle A2 follows the same principle and will not be elaborated further here.

[0016] Furthermore, the driving component includes a drive motor with a speed between 5 rpm and 100 rpm. A speed less than 5 rpm results in a large gear ratio and complex structure; a speed greater than 100 rpm causes the lid to flip too quickly, making it difficult to control and leading to water splashing. The first lid includes a metal layer and a plastic layer covering the outside of the metal layer. The plastic layer is pivotally connected to the pot body. The metal layer insulates the heat inside the cooking cavity, preventing the first lid from being damaged by heat, while the plastic layer shields the metal layer, improving the integrity of the first lid. The second lid includes a cantilever and a viewing cover. The first end of the cantilever is pivotally connected to the pot body, and the viewing cover is located at the second end of the cantilever. The cantilever is equipped with a water pipe and a spray nozzle. The spray nozzle can spray water towards the cooking cavity formed by the pot body and the lid to clean the cooking cavity or add water during cooking. Furthermore, users can see through the viewing cover to observe the cooking process inside the cooking cavity, facilitating subsequent operations. The viewing cover is opened and closed via a cantilever, offering advantages such as simple structure and low cost. The cooking appliance also includes a stirring element, which is rotatably mounted inside the cooking cavity formed by the pot body and the top cover, enabling the stirring element to stir-fry the food. The cooking appliance also includes a water tank, which is mounted on the pot body to supply water to the spray nozzle. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0046] like Figures 1 to 18 As shown, this embodiment of the present invention provides a cooking appliance, which includes a pot body 10, a lid 20, a driving component 30, and a transmission mechanism 40. The lid 20 includes a first lid body 21 and a second lid body 22. The first lid body 21 is closable and covers the opening 11 of the pot body 10, and has a feeding port 211. The second lid body 22 is closable and covers the feeding port 211. The driving component 30 is drivenly connected to the first lid body 21 and the second lid body 22 respectively through the transmission mechanism 40, and the driving component 30 can drive the first lid body 21 and the second lid body 22 to open or close. The transmission ratio of the transmission mechanism 40 is greater than or equal to 1:1.

[0047] Using the cooking appliance provided in this embodiment, the drive unit 30 is driven to the first cover 21 and the second cover 22 respectively via the transmission mechanism 40. The drive unit 30 can drive the first cover 21 and the second cover 22 to open or close, eliminating the need for the user to manually open or close the first cover 21 and the second cover 22. This improves the automation level of the cooking appliance, simplifies user operation, and enhances the user experience. Furthermore, since one drive unit can simultaneously drive the opening or closing of two covers (the first cover 21 and the second cover 22), the drive structure is simplified, reducing costs. In addition, because the transmission ratio of the transmission mechanism 40 is greater than or equal to 1:1, the drive unit 30 can transmit a sufficiently large torque to the first cover 21 and the second cover 22, making the opening and closing process of the first cover 21 and the second cover 22 more stable and effortless.

[0048] It should be noted that, in this embodiment, the ability of the driving component 30 to drive the first cover 21 and the second cover 22 to open or close means that the driving component 30 can drive the first cover 21 to switch between an open state and a closed state, and the driving component 30 can drive the second cover 22 to switch between an open state and a closed state.

[0049] Furthermore, in this embodiment, the driving element 30 is a single driving element. This allows for the simultaneous opening and closing of two covers using a single driving element, which simplifies the driving structure and reduces costs compared to using two separate driving elements to drive the opening and closing of the two covers.

[0050] Specifically, the driving component 30 is driven to the first cover 21 via the transmission mechanism 40, where the transmission ratio of the transmission mechanism 40 is greater than or equal to 1:1. The driving component 30 is also driven to the second cover 22 via the transmission mechanism 40, where the transmission ratio of the transmission mechanism 40 is also greater than or equal to 1:1.

[0051] The transmission ratio of the transmission mechanism 40 is between 1:1 and 10:1, so that the drive component 30 can transmit a sufficiently large torque to the first cover 21 and the second cover 22, and the cost and size of the transmission mechanism 40 will not be too large.

[0052] In other words, the transmission ratio of the transmission mechanism 40 can be 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, and other ratios between 1:1 and 10:1.

[0053] In this embodiment, the transmission ratio of the transmission mechanism 40 is between 1:1 and 3:1, so that the driving component 30 can transmit a sufficiently large torque to the first cover 21 and the second cover 22, and the cost and size of the transmission mechanism 40 will not be too large.

[0054] Specifically, the transmission ratio of the transmission mechanism 40 is 2:1.

[0055] like Figures 4 to 13 As shown, the transmission mechanism 40 includes a driving transmission member 41, a first driven transmission member 42, and a second driven transmission member 43. The driving transmission member 41 is rotatably mounted on the pot body 10, and the driving member 30 is drivenly connected to the driving transmission member 41. The driving transmission member 41 has a driving tooth 411. The first driven transmission member 42 is mounted on the first cover 21 and has a first driven tooth 421 capable of meshing with the driving tooth 411. The second driven transmission member 43 is mounted on the second cover 22 and has a second driven tooth 431 capable of meshing with the driving tooth 411. Using the above structure, the transmission is achieved through a gear structure, which has the advantages of simple and stable transmission structure.

[0056] The number of teeth of the first driven tooth 421 and the second driven tooth 431 is greater than or equal to the number of teeth of the driving tooth 411, so that the transmission ratio of the transmission mechanism 40 is greater than or equal to 1:1.

[0057] In this embodiment, the number of teeth of the driving tooth 411 is n. The number of teeth of the first driven tooth 421 is m, where m:n is between 1:1 and 10:1. The number of teeth of the second driven tooth 431 is p, where p:n is between 1:1 and 10:1.

[0058] By setting m:n between 1:1 and 10:1, and p:n between 1:1 and 10:1, the transmission ratio of the transmission mechanism 40 is between 1:1 and 10:1. In this way, the driving component 30 can transmit a sufficiently large torque to the first cover 21 and the second cover 22, and the cost and size of the transmission mechanism 40 will not be too large.

[0059] Where m:n can be 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, or other ratios between 1:1 and 10:1. p:n can be 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, or other ratios between 1:1 and 10:1.

[0060] In this embodiment, m:n and p:n are equal, both being 2:1. That is, for every one rotation of the cover, the active transmission component needs to rotate two times, resulting in smoother rotation at lower speeds.

[0061] like Figure 13As shown, the cooking appliance also includes a rotating shaft 60. The first cover 21 and the second cover 22 are both pivotally connected to the pot body 10 via the rotating shaft 60. Multiple teeth of the first driven gear 421 and the second driven gear 431 are arranged circumferentially around the rotating shaft 60. The distance D between the axis of the rotating shaft 60 and the axis of the driving transmission component 41 is 5mm ≤ D ≤ 30mm. Setting the distance D between the axis of the rotating shaft 60 and the axis of the driving transmission component 41 within the above range avoids both excessively small distances affecting gear machining and excessively large gears leading to large assembly space, thus affecting volume and assembly.

[0062] The distance D between the axis of the rotating shaft 60 and the axis of the active transmission component 41 can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, or other values ​​between 5mm and 30mm.

[0063] In this embodiment, the distance D between the axis of the rotating shaft 60 and the axis of the active transmission member 41 is 15mm≤D≤20mm.

[0064] The module of the driving gear 411, the first driven gear 421, and the second driven gear 431 is M, where 0.1 ≤ M ≤ 5. Setting the module M of the driving gear 411, the first driven gear 421, and the second driven gear 431 within the above range ensures that the cost is not too high due to the module being too low, and that the rotation is not prone to jamming due to the module being too large.

[0065] Specifically, M can be 0.1, 1, 2, 3, 4, 5, and other values ​​between 0.1 and 5.

[0066] In this embodiment, the module M is 1, which is convenient for production and the number of teeth is also appropriate.

[0067] like Figures 6 to 8 As shown, the active transmission component 41 includes an active shaft 412 and a first gear 413 and a second gear 414 disposed on the active shaft 412. The driving component 30 is drivenly connected to the active shaft 412. The first gear 413 and the second gear 414 are arranged along the axial direction of the active shaft 412. The first gear 413 has an active tooth 411 that can mesh with the first driven tooth 421, and the second gear 414 has an active tooth 411 that can mesh with the second driven tooth 431. Both the first gear 413 and the second gear 414 are incomplete gears. When the active shaft 412 rotates, the first gear 413 and the second gear 414 alternately mesh with the corresponding driven transmission component. By setting the first gear 413 and the second gear 414 as incomplete gears, and by utilizing the alternating meshing of the first gear 413 and the second gear 414 with the corresponding driven transmission component, the driving component 30 can drive the first cover 21 and the second cover 22 to open or close sequentially through the transmission mechanism 40.

[0068] It should be noted that when the drive shaft 412 rotates, the first gear 413 and the second gear 414 take turns meshing with the corresponding driven transmission components. The corresponding driven transmission components refer to: the first gear 413 corresponds to the first driven transmission component 42, and the second gear 414 corresponds to the second driven transmission component 43.

[0069] like Figure 5 , Figure 9 as well as Figure 10 As shown, the first driven transmission member 42 is a first arc-shaped rack 422, which extends around the rotation axis of the driving transmission member 41, and the first driven tooth 421 is disposed on the first arc-shaped rack 422. The second driven transmission member 43 is a second arc-shaped rack 432, which extends around the rotation axis of the driving transmission member 41, and the second driven tooth 431 is disposed on the second arc-shaped rack 432. Both the first arc-shaped rack 422 and the second arc-shaped rack 432 are arc-shaped structures. This structure, when used in conjunction with the incomplete gears of the first gear 413 and the second gear 414, can further simplify the structure of the first driven transmission member 42 and the second driven transmission member 43 and reduce costs, based on the fact that the driving member 30 drives the first cover 21 and the second cover 22 to open or close sequentially through the transmission mechanism 40.

[0070] In this embodiment, along the axial direction of the drive shaft 412, the projections of some of the driving teeth 411 on the first gear 413 overlap with the projections of some of the driving teeth 411 on the second gear 414. With this structure, the switching between the first gear 413 and the second gear 414 and their corresponding driven transmission components is smoother, reducing the likelihood of jamming.

[0071] In this embodiment, for every one revolution of the active transmission component 41, the first cover 21 and the second cover 22 rotate half a revolution. The two rows of partial teeth (active teeth 411) on the active transmission component 41 engage and disengage and switch, ensuring that the second cover 22 and the first cover 21 do not interfere with each other when flipping. Preferably, the active transmission component 41 should not rotate more than one revolution, that is, the rotation angle of the active transmission component 41 should be less than 360°.

[0072] Therefore, in this embodiment, the flip angle of the first cover 21 is A1, where 0 < A1 ≤ 90°. The flip angle of the second cover 22 is A2, where 0 < A2 ≤ 90°. The flip angles A1 and A2 can be 30°, 60°, 90°, or other values ​​within the aforementioned range.

[0073] It should be noted that if the flipping angle A1 of the first cover 21 is less than or equal to 0°, that is, the first cover 21 does not flip, there will be interference when taking out or putting in the inner pot; if the flipping angle A1 of the first cover 21 is greater than 90°, the active transmission component 41 will flip the double cover and rotate more than 360°, which is not feasible.

[0074] In this embodiment, the preferred flipping angle A1 of the first cover 21 is 70°≤A1≤85°.

[0075] When the active transmission component 41 flips the first cover 21, it needs to rotate by an angle O. The angle O is 100° < O ≤ 180°. If it is less than 100°, there will be interference when taking out the pot. If it exceeds 180°, there will be interference when rotating the second cover 22 and the first cover 21. The preferred angle O is 140° ≤ A1 ≤ 170°.

[0076] Similarly, the flipping angle A2 of the second cover 22 is the same as the above principle, and will not be repeated here.

[0077] In this embodiment, the driving component 30 includes a drive motor 31, the speed of which is between 5 rpm and 100 rpm. A speed less than 5 rpm results in a large gear ratio and complex structure; a speed greater than 100 rpm causes the cover to flip too quickly, making it difficult to control and resulting in water splashing. A speed of 8-12 rpm is preferred, ensuring smooth flipping and preventing water splashing.

[0078] like Figure 17 As shown, the first lid 21 includes a metal layer 212 and a plastic layer 213 that covers the outside of the metal layer 212. The plastic layer 213 is pivotally connected to the pot body 10. The metal layer 212 can insulate the heat inside the cooking cavity to prevent the first lid 21 from being damaged by heat, and the plastic layer 213 can cover the metal layer 212 to improve the integrity of the first lid 21.

[0079] like Figure 2 As shown, the second cover 22 includes a cantilever 221 and a viewing cover 222. The first end of the cantilever 221 is pivotally connected to the pot body 10, and the viewing cover 222 is located at the second end of the cantilever 221. A water pipe 223 and a spray nozzle 224 are provided on the cantilever 221. The spray nozzle 224 can spray water towards the cooking cavity formed by the pot body 10 and the upper cover 20 to clean the cooking cavity or add water during cooking. Furthermore, the user can see through the viewing cover 222 to observe the cooking process inside the cooking cavity, facilitating subsequent operations. Moreover, the opening and closing of the viewing cover 222 via the cantilever 221 has the advantages of simple structure and low cost.

[0080] In this embodiment, the spraying component 224 is a water-driven rotating nozzle.

[0081] The cooking appliance also includes a stirring element 70, which is rotatably disposed within the cooking cavity formed by the pot body 10 and the top cover 20. The stirring element 70 is capable of stirring food.

[0082] Specifically, the cooking appliance also includes a water tank 80, which is installed on the pot body 10, and a water pipe 223 is connected to the water tank 80 to supply water to the spray washing unit 224.

[0083] For example, 16 to Figure 18 As shown, in this embodiment, the cooking appliance also includes a fixed bracket 50. An active transmission component 41 is rotatably mounted on the fixed bracket 50, and the active transmission component 41 is axially positioned within the fixed bracket 50. A driving component 30 is mounted on the fixed bracket 50, and the fixed bracket 50 is connected to the pot body 10. The fixed bracket 50 enables the fixation of the active transmission component 41 and the driving component 30. Since the active transmission component 41 and the driving component 30 share a single bracket for fixation, the assembly structure is simplified.

[0084] The drive component 30 includes a drive motor 31, which has the advantages of easy control and simple structure.

[0085] The drive motor is fixed to the mounting bracket 50 using two screws, and the active transmission component is installed at the same time. The mounting bracket 50 is a U-shaped part.

[0087] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0088] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as exemplary only and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0089] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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 limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0090] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0091] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0092] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
