Description

Technical Field

[0001] This utility model belongs to the technical field of cooking machines, specifically relating to a stirring mechanism for a cooking machine. Background Technology

[0002] Automatic stir-fry machines have become increasingly popular in recent years, widely used in pre-prepared meal businesses and restaurants that require food processing. The core function of a stir-fry machine is to simulate manual cooking, especially the stirring motion, and the key component for achieving this is its internal stirring mechanism. The performance of the stirring mechanism directly determines the evenness of heating, the degree of mixing, and the final taste of the dish. Currently, most stir-fry machines suffer from the problem that the stirring range of the mechanism cannot cover the bottom of the pan, resulting in large stirring blind spots in the center and corners. Food cannot be effectively stirred in these areas, leading to severely uneven heating; some food becomes burnt while others remain uncooked, significantly impacting the cooking results. Therefore, increasing the stirring range of the mechanism is a technical problem that needs to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a stirring mechanism for a cooking machine, which can improve the stirring range of the cooking robot.

[0004] To achieve the aforementioned utility model objectives, the technical solution adopted by this utility model is as follows: This application provides a stirring mechanism for a cooking machine, installed on the base of a cooking robot, including a fixed base, a rotating arm, and a stirring assembly. The fixed base is installed on the base, the rotating arm is rotatably connected to the fixed base, and the stirring assembly includes a stirring disc and multiple stirring units. The stirring disc is rotatably connected to the rotating arm, and the multiple stirring units are equally spaced around the rotation axis of the stirring disc. Each stirring unit includes two stirring spatulas, which are radially spaced along the circumference of the stirring disc.

[0005] In some embodiments, two stirring units are provided.

[0006] In some embodiments, the stirring unit includes a support portion connected to the stirring pan and rotating around the circumference of the stirring pan. The support portion includes a first side and a second side disposed opposite to each other. Two stirring shovels are a first shovel and a second shovel, respectively. The first shovel is disposed on the first side and is inclined toward the second side. The second shovel is disposed on the second side and is inclined toward the first side.

[0007] In some embodiments, the rotating arm is also provided with a lid, which is annular and arranged around the circumference of the mixing plate.

[0008] In some embodiments, the lid is provided with a plurality of through holes around its circumference.

[0009] In some embodiments, along the axial direction of the lid, the lid includes a first end and a second end disposed opposite to each other, the first end abutting against a rotating arm, the rotating arm being provided with an elastic clip, the elastic clip passing through the lid, and the elastic clip abutting against the second end.

[0010] In some embodiments, the resilient card protrudes from the second end.

[0011] In some embodiments, the fixed base includes two opposing limiting arms, and a rotating arm is disposed between the two limiting arms.

[0012] In some embodiments, the rotating arm is provided with a drive bushing, the cross-section of which is polygonal, and a connecting hole is provided on the limiting arm opposite the drive bushing along the rotation axis of the rotating arm.

[0013] In some embodiments, a limiting arm is provided with an arc-shaped groove around the rotation axis of the rotating arm, and a limiting hole is provided on the rotating arm opposite the arc-shaped groove along the rotation axis of the rotating arm.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting the two stirring spatulas radially apart along the circumference of the stirring plate, the working range of a single stirring unit can simultaneously cover the central and edge areas of the bottom of the pot during one rotation, effectively increasing the stirring range.

[0016] 2. The two stirring spatulas work together when rotating. The spatula closer to the center of the pot can push the food in the center outward, while the spatula farther from the center can push the food on the edge of the pot inward. This promotes the flow of food in different areas and makes the stir-frying of food better.

[0017] 3. Ingredients near the edge of the pot and ingredients near the center of the pot can be stir-fried simultaneously, reducing the risk of overheating due to prolonged stagnation in a certain area and effectively improving the stir-frying effect.

[0018] 4. This device can simulate the process of a chef stirring the center and edges of the pan during manual cooking, making the stir-frying process similar to manual cooking. This makes the stir-frying process closer to the physical process of real cooking, which helps to bring out the aroma of the ingredients. Attached Figure Description

[0032] The technical solutions of the present invention 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 invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0033] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "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 utility model 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 utility model.

[0034] This application provides a stirring mechanism for a cooking machine, installed on the base 1 of a cooking robot, including a fixed base 2, a rotating arm 4, and a stirring assembly. The fixed base 2 is installed on the base 1, and the rotating arm 4 is rotatably connected to the fixed base 2. The stirring assembly includes a stirring plate 5 and multiple stirring units 6. The stirring plate 5 is rotatably connected to the rotating arm 4, and the multiple stirring units 6 are equally spaced around the rotation axis of the stirring plate 5. Each stirring unit 6 includes two stirring spatulas, which are radially spaced along the rotation circumference of the stirring plate 5.

[0035] The technical improvements in this application mainly target the stirring mechanism of the cooking robot. Other auxiliary components of the cooking robot, such as the feeding mechanism and the conveying mechanism, are well known to those skilled in the art and will not be described in detail here.

[0036] The mounting base 2 can be detachably connected to the base 1 of the cooking robot. For example, the mounting base 2 can be connected to the base 1 by bolts.

[0037] When the cooking robot is working, the pot is placed on the base 1, and the rotating arm 4 is rotatably connected to the fixed base 2. This allows the stirring component to rotate either towards or away from the pot. When the stirring component rotates towards the pot, the stirring spatula can enter the pot and stir the ingredients inside.

[0038] When the mixing plate 5 rotates towards the pot body to the set position, the mixing plate 5 can be placed flat on top of the pot body, and the center of the bottom of the pot is located at the rotation axis of the mixing plate 5.

[0039] The mixing plate 5 can be rotated by a motor.

[0040] The mixing plate 5 is rotatably connected to the rotating arm 4. When the mixing plate 5 rotates, the mixing unit 6 set on the mixing plate 5 can also rotate, so that the mixing unit 6 can stir and stir the ingredients in the pot.

[0041] The mixing unit 6 includes two mixing spatulas, which effectively increases the mixing range of the mixing unit 6.

[0042] By radially spacing the two stirring spatulas along the circumference of the stirring plate 5, a single stirring unit 6 can simultaneously cover both the central and edge areas of the pot bottom during one rotation, effectively increasing the stirring range. Furthermore, this arrangement allows the two spatulas to work synergistically during rotation: the spatula closer to the center moves the food outwards, while the spatula further away moves the food inwards from the edge, promoting food circulation and improving stir-frying efficiency. Additionally, the two spatulas ensure that food near the edge and center of the pot bottom is stirred simultaneously, reducing the risk of overheating due to prolonged stagnation in one area and further enhancing the stir-frying effect. Finally, this device simulates the process of a chef stirring the food in the center and edge of the pot during manual cooking, making the stir-frying process similar to real cooking and thus closer to the physical process of real cooking, which helps to bring out the aroma of the ingredients.

[0043] In some embodiments, two stirring units 6 are provided.

[0044] The included angle between the two stirring units 6 can be 180°, that is, one stirring unit 6 can rotate 180° around the rotation axis of the stirring plate 5 and move to the position of the other stirring unit 6.

[0045] Two stirring units 6 are configured. On the one hand, this reduces the number of stirring units 6 required while still meeting the stirring requirements, thus saving costs. On the other hand, this increases the dynamic balance performance during stirring, making the stirring mechanism operate more smoothly.

[0046] In some embodiments, the stirring unit 6 includes a support 7 connected to the stirring pan 5 and rotating around the circumference of the stirring pan 5. The support 7 includes a first side 8 and a second side 9 disposed opposite to each other. The two stirring shovels are a first shovel 10 and a second shovel 11, respectively. The first shovel 10 is disposed on the first side 8 and is inclined toward the second side 9. The second shovel 11 is disposed on the second side 9 and is inclined toward the first side 8.

[0047] The first shovel 10 and the second shovel 11 can be intersected. For example, when the first shovel 10 and the second shovel 11 are projected onto a reference plane perpendicular to the radial direction of the rotation circumference of the mixing plate 5, they can form an X-shaped structure.

[0048] by Figure 2Taking the current state as an example, when the stirring plate 5 rotates clockwise, the stirring spatula near the edge of the pot can flip the food, while the stirring spatula near the center of the pot can move the food, which facilitates the flow of the food towards the center of the pot. When the stirring plate 5 rotates counterclockwise, the stirring spatula near the center of the pot can flip the food, while the stirring spatula near the edge of the pot can move the food, which facilitates the flow of the food towards the edge of the pot. This setting, on the one hand, promotes the flow of food in different areas when the stirring spatula is stirring, increasing the stir-frying effect. On the other hand, regardless of whether the stirring plate 5 rotates clockwise or counterclockwise, it can stir-fry the food, and the clockwise and counterclockwise rotations can promote the movement of the food in different directions, further enhancing the stir-frying effect.

[0049] In some embodiments, the rotating arm 4 is also provided with a pot lid 12, which is annular and arranged around the circumference of the stirring plate 5.

[0050] The lid 12 is arranged around the circumference of the mixing plate 5. When the mixing plate 5 rotates to the top of the pot body, the lid 12 can cover the top of the pot body.

[0051] In some embodiments, the lid 12 is provided with a plurality of through holes 13 around its circumference.

[0052] The through-hole 13 can be used to install a transparent shield, such as glass. This allows the user to observe the contents of the pot from the outside while the stirring mechanism is operating.

[0053] In some embodiments, along the axial direction of the pot lid 12, the pot lid 12 includes a first end and a second end disposed opposite to each other. The first end abuts against the rotating arm 4, and the rotating arm 4 is provided with an elastic clip 14. The elastic clip 14 passes through the pot lid 12 and abuts against the second end.

[0054] When the first end of the pot lid 12 abuts against the rotating arm 4, it abuts against the second end through the elastic clip 14, so that the pot lid 12 can be fixed to the rotating arm 4.

[0055] The elastic card 14 is made of elastic material, which allows the elastic card 14 to undergo elastic deformation within a certain range.

[0056] The elastic clip 14 is inserted inside the pot lid 12, so that the elastic clip 14 can deform a certain distance away from the inner peripheral wall of the pot lid 12. This makes the elastic clip 14 no longer contact the second end, and the pot lid 12 can be removed from the rotating arm 4.

[0057] The pot lid 12 is secured by the elastic clip 14, making it easy to install and remove.

[0058] In some embodiments, the resilient card 14 protrudes from the second end.

[0059] The elastic clip 14 protrudes from the second end. This design facilitates the operation of the elastic clip 14 by the user when removing or installing the pot lid 12. On the other hand, the protrusion of the elastic clip 14 allows it to be set longer, making it easier to move.

[0060] In some embodiments, the fixed base 2 includes two opposing limiting arms 3, and a rotating arm 4 is disposed between the two limiting arms 3.

[0061] The rotating arm 4 is simultaneously connected to the two limiting arms 3, which increases the connection strength between the rotating arm 4 and the fixed base 2.

[0062] In this embodiment of the application, a blocking part 17 may be provided between the two limiting arms 3 to limit the rotation stroke of the rotating arm 4. For example, a mating part 18 may be provided on the side of the rotating arm 4 facing away from the pot. When the rotating arm 4 rotates to the limit position in the direction away from the pot, the mating part 18 abuts against the blocking part 17 to limit the rotation stroke of the rotating arm 4.

[0063] Furthermore, the two limiting arms 3 are connected by the blocking part 17, so that the two limiting arms 3 can form an integral structure, which increases the structural strength of the fixed base 2.

[0064] In some embodiments, the rotating arm 4 is provided with a drive bushing 16, the cross-section of the drive bushing 16 is polygonal, and the limiting arm 3 is provided with a connecting hole 15 opposite to the drive bushing 16 along the rotation axis of the rotating arm 4.

[0065] The drive shaft sleeve 16 can be connected to a drive component, allowing the rotating arm 4 to be driven to rotate. For example, the drive component can be a motor, and the output end of the motor can be connected to the drive shaft sleeve 16, allowing the motor to drive the rotating arm 4 to rotate.

[0066] The drive shaft sleeve 16 has a polygonal cross-section, which reduces the risk of slippage between the motor output end and the drive shaft sleeve 16, leading to a decrease in transmission efficiency. Specifically, the cross-sectional shape of the motor output end can be adapted to the cross-sectional shape of the drive shaft sleeve 16. Thus, when the motor output end is inserted into the drive shaft sleeve 16, the polygonal cross-section of the drive shaft sleeve 16 prevents relative slippage between the motor output end and the drive shaft sleeve 16.

[0067] The connecting hole 15 allows the drive component to be installed on the limiting arm 3, and after passing through the connecting hole 15, it is connected to the drive shaft sleeve 16.

[0068] In some embodiments, a limiting arm 3 is provided with an arc-shaped groove 19 around the rotation axis of the rotating arm 4, and a limiting hole 20 is provided on the rotating arm 4 opposite the arc-shaped groove 19 along the rotation axis of the rotating arm 4.

[0069] Limiting hole 20 is used to install limiting components.

[0070] When a limiting component is installed in the limiting hole 20, the limiting component passes through the arc groove 19, so that the limiting component and the arc groove 19 cooperate to limit the rotation stroke of the rotating arm 4.

[0071] For example, the limiting hole 20 can be a threaded hole, and the limiting member can be a component that can be threadedly engaged with the limiting hole 20, such as a bolt.

[0072] Furthermore, the rotational resistance of the rotating arm 4 can be adjusted by the cooperation of the limiting component and the arc groove 19. For example, when the limiting component is a bolt, the shank of the bolt can pass through the arc groove 19 and the limiting hole 20 and be threaded together. The head of the bolt abuts against the limiting arm 3. In this way, the tighter the bolt is, the greater the rotational resistance of the rotating arm 4. Conversely, the looser the bolt, the smaller the rotational resistance of the rotating arm 4.

[0073] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
