Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a transmission mechanism, a base, and a cooking device. Background Technology

[0002] With the development of technology, various intelligent cooking devices (such as stir-fry machines and food processors) have appeared on the market. Taking a stir-fry machine as an example, it has a lower clutch in the base and an upper clutch with a frying pan and frying blades in the wok. After the wok is placed on the base, the upper and lower clutches engage to transmit power and drive the frying blades. However, due to the limitations of the engagement structure between the upper and lower clutches, the base is not compatible with the use of two different cookware types: a wok with an upper clutch and a frying pan, resulting in poor versatility. Summary of the Invention

[0003] The main objective of this invention is to propose a transmission mechanism for use in the base of a cooking appliance, thereby improving the versatility of the base and enabling it to be compatible with the use scenarios of two different cookware: a functional pot with an upper clutch (such as a frying pan) and a flat-bottomed pan.

[0004] To achieve the above objectives, the present invention proposes a transmission mechanism for installation within the base of a cooking appliance, the base having a support surface for supporting a cookware, the transmission mechanism comprising:

[0005] The power input shaft extends along the height direction of the base body;

[0006] A clutch, drively connected to the power input shaft and capable of torque transmission, is also movable relative to the power input shaft to have an extended position protruding from the support surface and a retracted position not protruding from the support surface; and

[0007] A first drive assembly is used to drive the clutch to switch between the extended position and the retracted position.

[0008] In one embodiment, the clutch and the power input shaft are connected by a transmission assembly that is axially movable relative to the power input shaft. The first drive assembly is driven to the transmission assembly to drive the transmission assembly to move up and down axially relative to the power input shaft.

[0009] In one embodiment, the transmission mechanism further includes a fixing frame fixed relative to the base body. The fixing frame includes a fixing cylinder extending coaxially with the power input shaft. The power input shaft is rotatably mounted in the fixing cylinder via a first bearing. The transmission assembly is slidably mounted in the fixing cylinder along the axial direction. The clutch extends out from the top of the fixing cylinder.

[0010] In one embodiment, the fixed cylinder is provided with two first bearings spaced apart along the axial direction, and a bushing is also sleeved around the power input shaft. The two ends of the bushing abut against the two first bearings respectively. The inner circumferential surface of the fixed cylinder is provided with a first step and a first groove spaced apart along the axial direction. A first retaining spring is engaged in the first groove. The side of one of the first bearings away from the bushing abuts against the first step, and the side of the other first bearing away from the bushing abuts against the first retaining spring.

[0011] In one embodiment, the power input shaft is provided with two second slots spaced apart along the axial direction, and each second slot is engaged with a second retaining spring. One of the first bearings, on the side away from the bushing, abuts against one of the second retaining springs, and the other of the first bearings, on the side away from the bushing, abuts against the other second retaining spring.

[0012] In one embodiment, the transmission assembly includes a power output shaft, a second bearing, and a bearing sleeve, which are sequentially sleeved around the power input shaft from the inside out. The power output shaft is rotatably connected to the second bearing, the bearing sleeve is fixedly connected to the second bearing, the bearing sleeve is slidably engaged with the fixed cylinder, the first drive assembly is drivenly connected to the bearing sleeve, and the clutch is connected to the power output shaft.

[0013] In one embodiment, the outer periphery of the power output shaft is provided with a shoulder and a third retaining groove spaced axially, the third retaining groove is engaged with a third retaining spring, and the second bearing is limited and installed between the shoulder and the third retaining spring.

[0014] In one embodiment, the first drive assembly includes a first drive member and a first transmission unit. The first drive member is driven to the bearing sleeve via the first transmission unit. The first transmission unit is used to convert the torque output by the first drive member into a driving force that drives the bearing sleeve to move up and down axially.

[0015] In one embodiment, the first transmission unit includes a transmission component and a gear. The transmission component includes a rack and a shift fork located at one end of the rack. The rack meshes with the gear, and the gear is connected to the drive shaft of the first drive component. The fixed cylinder has a first sliding groove extending axially, and the shift fork has a second sliding groove that is inclined relative to the first sliding groove. The outer periphery of the bearing sleeve has a sliding shaft that slidably passes through the first sliding groove and the second sliding groove.

[0016] In one embodiment, the bearing sleeve is provided with the sliding shaft on opposite sides, and the fixed cylinder is provided with the first sliding groove on opposite sides corresponding to each sliding shaft. The shift fork includes two extension arms that are opposite to each other and spaced apart. Each extension arm is provided with the second sliding groove, and the fixed cylinder is located between the two extension arms.

[0017] In one embodiment, the transmission mechanism further includes a second drive assembly, which is drivenly connected to the power input shaft to drive the power input shaft to rotate.

[0018] In one embodiment, the second drive assembly includes a second drive member and a second transmission unit. The second drive member is driven to the power input shaft via the second transmission unit, and the second transmission unit is used to transmit the torque output by the second drive member to the power input shaft.

[0019] The present invention also proposes a transmission mechanism for installation within the base of a cooking appliance, the base having a support surface for supporting a cookware, the transmission mechanism comprising:

[0020] The power input shaft extends along the height direction of the base body;

[0021] The clutch, which is drively connected to the power input shaft and capable of transmitting torque, is also capable of lifting and lowering relative to the power input shaft, so that the clutch has an extended position protruding from the support surface and a retracted position not protruding from the support surface; and

[0022] The drive mechanism includes a shift fork and a drive assembly. The shift fork is connected to the clutch via a transmission connection, and the drive assembly is connected to the shift fork. The drive assembly is used to drive the shift fork to reciprocate, thereby causing the clutch to move up and down between the extended position and the retracted position.

[0023] In one embodiment, the transmission mechanism further includes a fixed cylinder fixed relative to the base body. The fixed cylinder extends coaxially with the power input shaft, and the power input shaft is rotatably mounted inside the fixed cylinder. The fixed cylinder is also provided with a transmission component that can move axially. The power input shaft is connected to the clutch via the transmission component, and the shift fork is connected to the clutch via the transmission component.

[0024] In one embodiment, the drive assembly is used to drive the shift fork to reciprocate in a direction perpendicular to the axis of the power input shaft, the fixed cylinder is provided with a first slide groove extending axially, the shift fork is provided with a second slide groove inclined relative to the first slide groove, and the transmission assembly is provided with a sliding shaft that slidably passes through the first slide groove and the second slide groove.

[0025] The present invention also provides a base for a cooking device, the base comprising:

[0026] The base body has an internal mounting cavity, and the top of the base body has a support surface for supporting the cookware. The support surface has a clearance hole communicating with the mounting cavity.

[0027] The transmission mechanism described above is located within the mounting cavity, and the clutch is positioned opposite to the clearance hole.

[0028] The present invention also proposes a cooking apparatus, including a pot and a base as described above, wherein the pot is detachably placed on the support surface.

[0029] The technical solution of this invention achieves torque transmission by connecting a clutch to a power input shaft, and allows the clutch to switch between an extended and retracted position relative to the power input shaft under the drive of a first drive assembly. When cooking with a functional pot (such as a frying pan) equipped with a clutch, the first drive assembly drives the clutch to the extended position protruding from the support surface. At this point, the clutch can engage with the upper clutch of the pot, achieving power transmission. In this engagement method, the upper clutch does not need to protrude from the pot body, allowing the bottom of the functional pot to be flat, thus enabling the functional pot to be placed horizontally. When cooking with a flat-bottomed pan, the first drive assembly drives the clutch downward to the retracted position, and then the flat-bottomed pan is placed on the support surface. In this way, both the functional pot and the flat-bottomed pan make contact with the support surface of the base body on a large flat surface, allowing the functional pot and the flat-bottomed pan to be used interchangeably on the base. When the transmission mechanism of this technical solution is applied to the base of the cooking device, it can improve the versatility of the base, making it compatible with the use scenarios of two different cookware, namely a functional pot (such as a frying pan) with an upper clutch and a flat-bottomed pan.

[0040] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0043] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0044] Traditional cooking appliances have poor base versatility, as their bases are incompatible with both functional pots with upper clutches and frying pans. Take a stir-fry machine as an example: it typically consists of a base and a wok, which is a functional pot with an upper clutch. There are two ways the wok and base can be connected: one where the upper clutch protrudes from the pot and the lower clutch is recessed into the base (this design prevents the wok from being laid flat after being removed); the other where the lower clutch protrudes from the base and remains fixed (this design prevents the frying pan from being laid flat on the base). Therefore, stir-fry machines have poor base versatility and are incompatible with both functional pots and frying pans.

[0045] This invention proposes a transmission mechanism 100 for the base of a cooking device, enabling the base to be compatible with the use scenarios of two different cookware: a functional pot with an upper clutch and a flat-bottomed pan 32. For ease of explanation, the functional pot with an upper clutch in the following embodiments is mainly described using a wok 31 as an example. It should be understood that in practical applications, the functional pot is not limited to the wok 31; for example, it can also be a food preparation pot.

[0046] Reference Figure 1 , Figure 3 , Figure 6 and Figure 7In one embodiment of the present invention, the rotating mechanism is installed within the base body 200 of the cooking apparatus. The base body 200 has a support surface for supporting the cookware. The transmission mechanism 100 includes a power input shaft 10, a clutch 20, and a first drive assembly 60. The power input shaft 10 extends along the height direction of the base body 200. The clutch 20 is drively connected to the power input shaft 10 and can transmit torque. The clutch 20 is also movable relative to the power input shaft 10, so that the clutch 20 has an extended position protruding from the support surface and a retracted position not protruding from the support surface. The first drive assembly 60 is used to drive the clutch 20 to switch between the extended position and the retracted position.

[0047] In this embodiment, the clutch 20 protrudes from the support surface to cooperate with a functional pot (such as a wok 31) equipped with an upper clutch, while the clutch 20 does not protrude from the support surface to accommodate a flat-bottomed pan 32. The transmission mechanism 100 is mainly used to transmit power between the clutch 20 and the upper clutch of the pot. The power input shaft 10 extends along the height of the base body 200, and the clutch 20 is connected to the power input shaft 10 for torque transmission. When the power input shaft 10 rotates under the drive of other driving components, it transmits torque to the clutch 20, allowing the clutch 20 to rotate together with the power input shaft 10. When the clutch 20 engages with the upper clutch of the pot, the clutch 20 further transmits torque to the upper clutch to drive its rotation. It should be noted that the clutch 20 and the power input shaft 10 can be directly connected to transmit torque, or the clutch 20 and the power input shaft 10 can be connected via a transmission assembly 30 to transmit torque. Furthermore, the clutch 20 can also move relative to the power input shaft 10, allowing it to switch between an extended and retracted position under the driving action of the first drive assembly 60. Specifically, the clutch 20 can slide or rotate relative to the power input shaft 10. For example, the clutch 20 can slide axially relative to the power input shaft 10, switching between an extended and retracted position under the action of the first drive assembly 60; or, for another example, the clutch 20 can rotate about an axis perpendicular to the power input shaft 10, switching between an extended and retracted position. It should be noted that in the retracted position, the clutch 20 does not protrude from the support surface; specifically, the clutch 20 can be flush with the support surface or lower than the support surface.

[0048] The technical solution of the present invention achieves torque transmission by connecting the clutch 20 to the power input shaft 10, and allows the clutch 20 to switch between an extended position and a retracted position relative to the power input shaft 10 under the drive of the first drive assembly 60. Figure 6As shown, when cooking is required using a multi-functional cookware with a clutch (such as a frying pan 31), the first drive assembly 60 drives the clutch 20 to extend beyond the support surface. At this point, the clutch 20 can engage with the upper clutch of the cookware, thus transmitting power. In this configuration, the upper clutch does not need to protrude beyond the cookware body, allowing the bottom of the multi-functional cookware to be flat, enabling it to be placed horizontally. Figure 7 As shown, when cooking with the frying pan 32 is required, the first drive assembly 60 drives the clutch 20 downward to the retracted position, and then the frying pan 32 is placed on the support surface. This ensures that the functional pot, the frying pan 32, and the support surface of the base body 200 are all in large-plane contact, allowing for switching between the functional pot and the frying pan 32 on the base. When the transmission mechanism 100 of this technical solution is applied to the base of the cooking device, it improves the versatility of the base, enabling it to be compatible with the use scenarios of two different cookware: a functional pot with an upper clutch (such as a frying pan 31) and a frying pan 32.

[0049] Optionally, in the retracted position, the clutch 20 is positioned below the support surface of the base body 200. This ensures that when cooking with the frying pan 32, there is a certain gap between the clutch 20 and the bottom of the frying pan 32. This prevents the clutch 20 from pressing against the frying pan 32 and creating indentations, and also effectively blocks heat transfer between the frying pan 32 and the clutch 20.

[0050] In one embodiment, the clutch 20 and the power input shaft 10 are connected by a transmission assembly 30, which is axially slidable relative to the power input shaft 10. A first drive assembly 60 is driven to connect to the transmission assembly 30, thereby driving the transmission assembly 30 to move up and down axially relative to the power input shaft 10. Specifically, the transmission assembly 30 is connected between the clutch 20 and the power input shaft 10, and can transmit the torque of the power input shaft 10 to the clutch 20, thereby causing the clutch 20 to rotate synchronously with the power input shaft 10. By driving the transmission assembly 30 to move up and down axially relative to the power input shaft 10 through the first drive assembly 60, the clutch 20 can be slidably switched between the extended and retracted positions.

[0051] Please refer to Figure 1 and Figure 3 In one embodiment, the transmission mechanism 100 further includes a fixing frame 40 for fixing within the base body 200. The fixing frame 40 includes a fixing cylinder 41 that extends coaxially with the power input shaft 10. The power input shaft 10 is rotatably mounted within the fixing cylinder 41 via a first bearing 51. The transmission assembly 30 is axially slidably mounted within the fixing cylinder 41. The clutch 20 extends out from the top of the fixing cylinder 41.

[0052] In this embodiment, multiple components of the transmission mechanism 100 (such as the power input shaft 10 and the transmission assembly 30) can be integrated into one unit using the mounting bracket 40, so that the transmission mechanism 100 can be installed as a whole within the base body 200. Of course, in some embodiments, the installation of each component of the transmission mechanism 100 can also be achieved through the mounting structure of the base body 200 itself. Specifically, the mounting bracket 40 may include a horizontally placed support plate 42 and a fixing cylinder 41 disposed on the upper surface of the support plate 42. The fixing cylinder 41 extends along the height direction of the base body 200, and both ends of the fixing cylinder 41 are open. The power input shaft 10 can be rotatably mounted in the fixing cylinder 41 via the first bearing 51. The transmission assembly 30 is sleeved on the top of the power input shaft 10 and can slide up and down relative to the power input shaft 10 along the axial direction. The clutch 20 is disposed on the top of the transmission assembly 30. When the transmission assembly 30 slides relative to the power input shaft 10, the inner circumferential surface of the fixed cylinder 41 slides in contact with the outer circumferential surface of the transmission assembly 30. The fixed cylinder 41 can also guide the axial sliding of the transmission assembly 30.

[0053] To ensure the installation stability of the power input shaft 10, in one embodiment, at least two first bearings 51 are axially mounted on the fixed cylinder 41, with the power input shaft 10 engaging with the inner rings of each first bearing 51. In this embodiment, by simultaneously supporting the power input shaft 10 with at least two first bearings 51, the installation stability of the power input shaft 10 can be ensured, thereby ensuring smoother rotation of the power input shaft 10. The number of first bearings 51 can be two, three, or more. Optionally, in this embodiment, two first bearings 51 are provided.

[0054] Please refer to Figure 3 and Figure 4 Furthermore, the fixed cylinder 41 is provided with two first bearings 51 spaced apart along the axial direction, and the power input shaft 10 is also sleeved with a bushing 52. The two ends of the bushing 52 abut against the two first bearings 51 respectively. The inner circumferential surface of the fixed cylinder 41 is provided with a first step 411 and a first groove spaced apart along the axial direction. The first groove is engaged with a first retaining spring 53. The side of one first bearing 51 away from the bushing 52 abuts against the first step 411, and the side of the other first bearing 51 away from the bushing 52 abuts against the first retaining spring 53.

[0055] Specifically, in this embodiment, the inner circumferential surface of the bottom of the fixed cylinder 41 is provided with an annular first step 411, and the inner circumferential surface of the fixed cylinder 41 is provided with an annular first groove corresponding to the top of the first step 411. A first retaining spring 53 is engaged in the first groove, and the first retaining spring 53 is opposite to and spaced apart from the first step 411. The bottom of the lower first bearing 51 can be limited by the first step 411, and the top of the upper first bearing 51 can be limited by the first retaining spring 53. The bushing 52 is limited and abuts between the two first bearings 51. In this way, the axial sides of the upper and lower first bearings 51 can be axially limited, preventing axial movement between the first bearings 51 and the fixed cylinder 41.

[0056] To prevent axial movement between the power input shaft 10 and the first bearing 51, the power input shaft 10 is further provided with two second retaining grooves spaced apart along the axial direction. Each second retaining groove is fitted with a second retaining spring 54. The side of one first bearing 51 away from the bushing 52 abuts against one of the second retaining springs 54, and the side of the other first bearing 51 away from the bushing 52 abuts against the other second retaining spring 54. Specifically, the outer circumferential surface of the power input shaft 10 is provided with two second retaining grooves. After the power input shaft 10 and the two first bearings 51 are assembled, the two second retaining springs 54 are respectively engaged in the two second retaining grooves, making assembly simple and convenient. Through the cooperation of the two second retaining springs 54, the axial movement of the power input shaft 10 can be restricted, thereby preventing axial movement of the power input shaft 10 relative to the first bearing 51, and further improving the rotational smoothness of the power input shaft 10.

[0057] Power can be transmitted between the power input shaft 10 and the clutch 20 via the transmission assembly 30. Please refer to... Figure 4 and Figure 5 In one embodiment, the transmission assembly 30 includes a power output shaft 31, a second bearing 32, and a bearing sleeve 33, which are sequentially sleeved around the power input shaft 10 from the inside out. The power output shaft 31 is rotatably connected to the second bearing 32, the bearing sleeve 33 is fixedly connected to the second bearing 32, the bearing sleeve 33 is slidably engaged with the fixed cylinder 41, the first drive assembly 60 is drivenly connected to the bearing sleeve 33, and the clutch 20 is connected to the power output shaft 31.

[0058] In this embodiment, the power output shaft 31 may include a first shaft segment and a second shaft segment connected to each other. The bottom of the first shaft segment has a socket, into which the power input shaft 10 is inserted, and the power input shaft 10 and the first shaft segment can transmit torque. The second shaft segment is inserted into the socket at the bottom of the clutch 20 and can also transmit torque. A second bearing 32 is sleeved on the periphery of the first shaft segment of the power output shaft 31, and can support the power output shaft 31. At the same time, the power output shaft 31 can transmit power relative to the second bearing 32. A bearing sleeve 33 is sleeved on the periphery of the second bearing 32, and the bearing sleeve 33 is fixed to the second bearing 32. Of course, in some embodiments, the bearing sleeve 33 and the second bearing 32 can also be combined into one part. When the power input shaft 10 rotates, it can transmit torque to the clutch 20 via the power output shaft 31, thereby realizing the synchronous rotation of the power input shaft 10, the power output shaft 31, and the clutch 20. When it is necessary to achieve the axial lifting and lowering movement of the clutch 20, the first drive assembly 60 drives the bearing sleeve 33 to slide relative to the fixed cylinder 41 axially, thereby driving the second bearing 32, the power output shaft 31 and the clutch 20 as a whole to lift and lower, so as to achieve the switching of the clutch 20 between the extended position and the retracted position.

[0059] To prevent axial movement of the power output shaft 31 relative to the second bearing 32, the outer circumference of the power output shaft 31 is further provided with a shoulder 311 and a third retaining groove at axial intervals. A third retaining spring 34 is engaged in the third retaining groove, and the second bearing 32 is positioned between the shoulder 311 and the third retaining spring 34. Specifically, the power output shaft 31 includes a first shaft segment and a second shaft segment connected to each other. The first shaft segment is inserted into the power input shaft 10, and the second shaft segment is inserted into the clutch 20. An annular shoulder 311 is provided on the outer circumferential surface of the first shaft segment near the second shaft segment, and an annular third retaining groove is provided on the outer circumferential surface of the first shaft segment away from the shoulder 311. The third retaining spring 34 is engaged in the third retaining groove. The engagement of the shoulder 311 and the third retaining spring 34 provides axial positioning of the second bearing 32. To prevent wear caused by direct contact between the second bearing 32 and the shoulder 311 and the third retaining ring 34, optionally, two washers 35 are fitted around the power output shaft 31. One washer 35 is located between the shoulder 311 and the second bearing 32, and the other washer 35 is located between the second bearing 32 and the third retaining ring 34. The washers 35 can be made of materials with low wear coefficients, such as rubber, polytetrafluoroethylene, or other non-metallic materials, thereby ensuring a longer service life for the washers 35.

[0060] Furthermore, such as Figure 4As shown, the inner circumferential surface of the fixed cylinder 41 is provided with a second step 412, and the outer circumference of the second bearing 32 is provided with a flange 321. The bottom surface of the flange 321 abuts against the second step 412, and the bottom surface of the bearing sleeve 33 abuts against the top surface of the flange 321. Specifically, the bottom outer circumference of the second bearing 32 is provided with an annular flange 321. After the second bearing 32 is assembled into the fixed cylinder 41, the second bearing 32 can overlap the second step 412 through the flange 321. The second step 412 can restrict the downward movement of the second bearing 32. In addition, the flange 321 can also provide axial support for the bearing sleeve 33.

[0061] The first drive assembly 60 is used to drive the bearing sleeve 33 to slide axially relative to the fixed cylinder 41, thereby realizing the lifting and lowering movement of the transmission assembly 30 and the clutch 20. There are various specific structures for the first drive assembly 60. For example, the first drive assembly 60 can use a linear drive element (such as an electric push rod) to directly apply a linear driving force to the bearing sleeve 33, or the first drive assembly 60 can use a rotary drive element in cooperation with the transmission unit to convert the rotary driving force of the rotary drive element into a linear driving force on the bearing sleeve 33 via the transmission unit.

[0062] Please refer to Figure 1 In one embodiment, the first drive assembly 60 includes a first drive member 61 and a first transmission unit. The first drive member 61 is drivenly connected to the bearing sleeve 33 via the first transmission unit. The first transmission unit is used to convert the torque output by the first drive member 61 into a driving force that drives the bearing sleeve 33 to move up and down axially. Specifically, the first drive member 61 can be a drive motor. When the drive motor is working, torque output can be achieved by rotating the drive shaft of the drive motor. The specific structure of the first transmission unit can be varied, including but not limited to a gear and rack transmission structure, a nut and screw transmission structure, a crank and connecting rod transmission structure, etc., as long as the torque output by the first drive member 61 can be converted into a linear driving force through the first transmission unit. In this embodiment, by setting the first transmission unit between the first drive member 61 and the bearing sleeve 33 for power transmission, the arrangement position of the first drive member 61 is more flexible, thereby better matching the internal space of the base body 200. For example, when the height space of the base body 200 is insufficient, the first drive member 61 can be arranged horizontally on one side of the radial direction of the bearing sleeve 33.

[0063] Please combine Figures 1 to 3In one embodiment, the first transmission unit includes a transmission member 62 and a gear 63. The transmission member 62 includes a rack 621 and a shift fork 622 disposed at one end of the rack 621. The rack 621 meshes with the gear 63. The gear 63 is connected to the drive shaft of the first drive member 61. The fixed cylinder 41 is provided with a first sliding groove 413 extending axially. The shift fork 622 is provided with a second sliding groove 623 that is inclined relative to the first sliding groove 413. The outer periphery of the bearing sleeve 33 is provided with a sliding shaft 331, which slidably passes through the first sliding groove 413 and the second sliding groove 623.

[0064] Specifically, the first driving member 61 is horizontally spaced on one side of the fixed cylinder 41, the rack 621 extends horizontally between the first driving member 61 and the fixed cylinder 41, and the shift fork 622 is located on the side of the rack 621 near the fixed cylinder 41. The fixed cylinder 41 has a first sliding groove 413 extending axially, and the shift fork 622 has a second sliding groove 623, which is inclined relative to the first sliding groove 413. The sliding shaft 331 passes through both the first sliding groove 413 and the second sliding groove 623, and the movement of the sliding shaft 331 can be guided by the cooperation of the first sliding groove 413 and the second sliding groove 623. To facilitate the assembly of the sliding shaft 331 with the first sliding groove 413, optionally, the top of the first sliding groove 413 penetrates the fixed cylinder 41 to form an opening. When the clutch 20 needs to move up and down, the first driving member 61 drives the gear 63 to rotate, which in turn drives the rack 621 and the shift fork 622 to move linearly back and forth in the horizontal direction. The second sliding groove 623 on the shift fork 622 can apply force to the sliding shaft 331, which can drive the sliding shaft 331 to move linearly back and forth along the first sliding groove 413, thereby realizing the axial up and down linear back and forth motion of the bearing sleeve 33 relative to the fixed cylinder 41.

[0065] Furthermore, such as Figure 2 As shown, the bearing sleeve 33 has sliding shafts 331 on opposite sides, and the fixed cylinder 41 has first sliding grooves 413 on opposite sides corresponding to each sliding shaft 331. The shift fork 622 includes two opposite and spaced-apart extension arms, each extension arm having a second sliding groove 623. The fixed cylinder 41 is located between the two extension arms. Specifically, the shift fork 622 may include a connecting arm connected to the rack 621, and extension arms extending from both ends of the connecting arm toward the end away from the rack 621. The two extension arms define an accommodating space for accommodating the fixed cylinder 41. The bearing sleeve 33 has sliding shafts 331 on opposite sides along the radial direction. Each sliding shaft 331 passes through the corresponding first sliding groove 413 and second sliding groove 623. In this way, the two extension arms of the shift fork 622 can simultaneously support the bearing sleeve 33, making the installation of the bearing sleeve 33 more stable; and the two second sliding grooves 623 can drive the corresponding sliding shafts 331 to move, making the sliding of the bearing sleeve 33 more stable.

[0066] Based on the above embodiments, the transmission mechanism 100 further includes a second drive assembly 70, which is drivenly connected to the power input shaft 10 to drive the power input shaft 10 to rotate. For example, when the wok 31 is needed, the wok 31 with an upper clutch is placed on the support surface of the base body 200. The upper clutch of the wok engages with the clutch 20 of the transmission mechanism 100. The second drive assembly 70 provides rotational power to the power input shaft 10, thereby driving the power input shaft 10 to rotate. In turn, the power input shaft 10 drives the clutch 20 to rotate, and the power is transmitted to the upper clutch through the clutch 20. The upper clutch drives the cooking knife to rotate to achieve the automatic cooking function. Optionally, the transmission mechanism 100 includes a fixed frame 40, and the second drive assembly 70 is mounted on the fixed frame 40. For example, the fixed frame 40 may include a support plate 42 and a fixed cylinder 41 disposed on the support plate 42. The power input shaft 10 is rotatably mounted on the fixed cylinder 41, and the second drive assembly 70 is mounted on the support plate 42.

[0067] like Figure 3 As shown, in one embodiment, the second drive assembly 70 includes a second drive member 71 and a second transmission unit. The second drive member 71 is driven to the power input shaft 10 via the second transmission unit, and the second transmission unit is used to transmit the torque output by the second drive member 71 to the power input shaft 10. In this embodiment, by setting the second transmission unit between the second drive member 71 and the power input shaft 10 for power transmission, the arrangement of the second drive member 71 becomes more flexible, thereby better matching the internal space of the base body 200. For example, in this embodiment, arranging the second drive member 71 and the power input shaft 10 side by side in the horizontal direction can minimize the height of the base body 200, making the overall thickness of the base thinner.

[0068] The second transmission unit includes, but is not limited to, belt pulley drives, gear sets, or other structures capable of power transmission. For example, in one embodiment, the second transmission unit includes a first transmission wheel 72, a second transmission wheel 73, and a transmission belt. The first transmission wheel 72 is connected to the drive shaft of the second drive member 71, the second transmission wheel 73 is connected to the power input shaft 10, and the transmission belt is wound around the periphery of the first transmission wheel 72 and the second transmission wheel 73. Using a transmission belt in conjunction with the first transmission wheel 72 and the second transmission wheel 73 to achieve synchronous belt drive results in a simple structure and reliable transmission.

[0069] Please refer to Figure 6 and Figure 7The present invention also proposes a base for a cooking device, the base including a base body 200 and a transmission mechanism 100. The base body 200 has an internal mounting cavity 201, and its top has a support surface for supporting a cookware, the support surface having a clearance hole communicating with the mounting cavity 201; the transmission mechanism 100 is disposed within the mounting cavity 201, and a clutch 20 is disposed opposite to the clearance hole. The specific structure of the transmission mechanism 100 is as described in the above embodiments. Since this base adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0070] In this embodiment, the base body 200 is used to realize the main functions of the base (such as heating function, electronic control function, etc.). The transmission mechanism 100 is used to realize the power transmission function between the clutch 20 and the upper clutch of the pot. When it is necessary to use a functional pot with an upper clutch (such as a frying pan 31) for cooking, the first drive component 60 drives the clutch 20 to move to the extended position protruding from the support surface. At this time, the clutch 20 can engage with the upper clutch of the pot to realize power transmission. In this engagement mode, the upper clutch does not need to protrude from the pot body of the functional pot, so that the bottom of the functional pot can be set as a flat surface, thereby realizing the flat placement of the functional pot. When it is necessary to use a frying pan 32 for cooking, the first drive component 60 drives the clutch 20 to move downward to the retracted position, and then the frying pan 32 is placed on the support surface. In this way, the functional pot and the frying pan 32 are in contact with the support surface of the base body 200, and the functional pot and the frying pan 32 can be switched on the base. This improves the versatility of the base, enabling it to be compatible with two different cookware scenarios: a functional pot with an upper clutch (such as a frying pan 31) and a frying pan 32.

[0071] Please refer to Figures 1 to 3 The present invention also proposes a transmission mechanism 100 for installation within a base body 200 of a cooking appliance. The base body 200 has a support surface for supporting a cookware. The transmission mechanism 100 includes a power input shaft 10, a clutch 20, and a drive mechanism. The power input shaft 10 extends along the height direction of the base body 200. The clutch 20 is drivenly connected to the power input shaft 10 and can transmit torque. The clutch 20 can also move up and down relative to the power input shaft 10, so that the clutch 20 has an extended position protruding from the support surface and a retracted position not protruding from the support surface. The drive mechanism includes a shift fork 622 and a drive assembly. The shift fork 622 is drivenly connected to the clutch 20, and the drive assembly is connected to the shift fork 622. The drive assembly is used to drive the shift fork 622 to reciprocate, thereby driving the clutch 20 to move up and down between the extended position and the retracted position.

[0072] In this embodiment, the drive assembly drives the shift fork 622 to reciprocate, thereby causing the clutch 20 to move up and down relative to the power input shaft 10, allowing the clutch 20 to switch between an extended position and a retracted position. Specifically, the drive assembly can drive the shift fork 622 to reciprocate along the axial direction of the power input shaft 10 to cause the clutch 20 to move up and down. Alternatively, the drive assembly can drive the shift fork 622 to reciprocate in a direction perpendicular to the axis of the power input shaft 10 (e.g., horizontally) to cause the clutch 20 to move up and down.

[0073] The technical solution of this invention achieves torque transmission by connecting the clutch 20 to the power input shaft 10, and the drive mechanism drives the shift fork 622 to reciprocate through the drive assembly, thereby enabling the clutch 20 to switch between the extended and retracted positions via the shift fork 622. Figure 6 As shown, when cooking is required using a multi-functional cookware with a clutch (such as a frying pan 31), the drive mechanism drives the clutch 20 to extend beyond the support surface. At this point, the clutch 20 engages with the upper clutch of the cookware, enabling power transmission. In this configuration, the upper clutch does not need to protrude beyond the cookware body, allowing the bottom of the multi-functional cookware to be flat, thus enabling it to be placed horizontally. Figure 7 As shown, when cooking with the frying pan 32 is required, the drive mechanism drives the clutch 20 downwards to the retracted position, and then the frying pan 32 is placed on the support surface. This ensures that the functional pot, the frying pan 32, and the support surface of the base body 200 are all in large-plane contact, allowing for switching between the functional pot and the frying pan 32 on the base. When the transmission mechanism 100 of this technical solution is applied to the base of the cooking device, it improves the versatility of the base, enabling it to be compatible with the use scenarios of two different cookware types: a functional pot with an upper clutch (such as a frying pan 31) and a frying pan 32.

[0074] Please refer to Figures 3 to 5 In one embodiment, the transmission mechanism 100 further includes a fixed cylinder 41 fixed relative to the base body 200. The fixed cylinder 41 extends coaxially with the power input shaft 10. The power input shaft 10 is rotatably installed in the fixed cylinder 41. The fixed cylinder 41 is also provided with a transmission assembly 30 that can move axially. The power input shaft 10 and the clutch 20 are connected by transmission assembly 30. The shift fork 622 and the clutch 20 are connected by transmission assembly 30.

[0075] Specifically, the transmission mechanism 100 may include a fixed frame 40 fixed to the base body 200. The fixed frame 40 may include a horizontally placed support plate 42 and a fixed cylinder 41 disposed on the upper surface of the support plate 42. Both ends of the fixed cylinder 41 are open. The power input shaft 10 is rotatably mounted in the fixed cylinder 41 via a first bearing 51. The transmission assembly 30 is sleeved on the top of the power input shaft 10 and can move up and down axially relative to the power input shaft 10. The clutch 20 is disposed on the top of the transmission assembly 30 and extends out of the fixed cylinder 41.

[0076] In this embodiment, a single transmission assembly 30 can achieve both power transmission between the power input shaft 10 and the clutch 20, and power transmission between the shift fork 622 and the clutch 20, resulting in a more compact overall structure. Specifically, when the power input shaft 10 rotates, the transmission assembly 30 can drive the clutch 20 to rotate; when the drive assembly drives the shift fork 622 to reciprocate, the transmission assembly 30 can drive the clutch 20 to move up and down relative to the power input shaft 10 along the axial direction. Furthermore, when the transmission assembly 30 slides relative to the power input shaft 10, the inner circumferential surface of the fixed cylinder 41 slides against the outer circumferential surface of the transmission assembly 30, and the fixed cylinder 41 also provides a certain guiding effect for the axial sliding of the transmission assembly 30.

[0077] Please refer to Figure 1 and Figure 2 In one embodiment, the drive assembly is used to drive the shift fork 622 to reciprocate in a direction perpendicular to the axis of the power input shaft 10. The fixed cylinder 41 is provided with a first slide groove 413 extending axially, the shift fork 622 is provided with a second slide groove 623 inclined relative to the first slide groove 413, and the transmission assembly 30 is provided with a sliding shaft 331 that slidably passes through the first slide groove 413 and the second slide groove 623.

[0078] In this embodiment, the axis of the power input shaft 10 extends vertically, and the drive assembly drives the shift fork 622 to reciprocate horizontally. The fixed cylinder 41 is provided with a first sliding groove 413 extending vertically, and the shift fork 622 is provided with a second sliding groove 623 inclined relative to the vertical. The sliding shaft 331 of the transmission assembly 30 passes through the intersection of the first sliding groove 413 and the second sliding groove 623. When the drive assembly drives the shift fork 622 to move horizontally, a driving force is generated on the sliding shaft 331 through the groove wall of the second sliding groove 623. Under the guidance of the first sliding groove 413, the sliding shaft 331 can slide reciprocally along the first sliding groove 413, thereby realizing the transmission assembly 30 driving the clutch 20 to achieve lifting and lowering movement. To facilitate the assembly of the sliding shaft 331 and the first sliding groove 413, optionally, the top of the first sliding groove 413 penetrates through the fixed cylinder 41 to form an opening.

[0079] To further ensure the motion stability of the transmission component 30, such as Figure 2 As shown, in one embodiment, the transmission assembly 30 has sliding shafts 331 on opposite sides, and the fixed cylinder 41 has first sliding grooves 413 on opposite sides corresponding to each sliding shaft 331. The shift fork 622 includes two opposite and spaced-apart extension arms, each extension arm having a second sliding groove 623, and the fixed cylinder 41 is located between the two extension arms. Thus, the two extension arms of the shift fork 622 can simultaneously support the transmission assembly 30, making the installation of the transmission assembly 30 more stable; and the two second sliding grooves 623 can drive the corresponding sliding shafts 331 to move, making the sliding of the transmission assembly 30 more stable.

[0080] There are various specific structures for the transmission assembly 30, such as Figure 5 As shown, in one embodiment, the transmission assembly 30 includes a power output shaft 31, a second bearing 32, and a bearing sleeve 33, which are sequentially sleeved around the power input shaft 10 from the inside to the outside. The power output shaft 31 is rotatably connected to the second bearing 32, and the bearing sleeve 33 is fixedly connected to the second bearing 32. The outer circumferential surface of the bearing sleeve 33 is provided with a sliding shaft 331.

[0081] In the above embodiments, there are various ways in which the drive assembly drives the shift fork 622 to achieve reciprocating motion. For example, the drive assembly can drive the shift fork 622 to reciprocate by cooperating with a drive motor and a gear rack, or the drive assembly can drive the shift fork 622 to reciprocate by cooperating with a drive motor and a nut screw, or the drive motor can drive the shift fork 622 to reciprocate by cooperating with other transmission structures.

[0082] like Figure 2 and Figure 3 As shown, in one embodiment, the drive assembly includes a first drive member 61, a gear 63, and a rack 621. The gear 63 is connected to the drive shaft of the first drive member 61, and the gear 63 meshes with the rack 621. A shift fork 622 is connected to one end of the rack 621. Specifically, the first drive member 61 can be horizontally spaced on one side of the fixed cylinder 41, the rack 621 extends horizontally between the first drive member 61 and the fixed cylinder 41, and the shift fork 622 is located at the end of the rack 621 near the fixed cylinder 41. The first drive member 61 drives the gear 63 to rotate, which in turn drives the rack 621 and the shift fork 622 to move horizontally. The shift fork 622 drives the transmission assembly 30 and the clutch 20 to move up and down. The overall structure is simple and the transmission is reliable.

[0083] Please refer to Figure 6 and Figure 7The present invention also proposes a cooking device, including a pot and a base, wherein the pot can be detachably placed on a supporting surface. The specific structure of the base is as described in the above embodiments. Since this cooking device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0084] The cookware may include a functional pot and a frying pan 32. The functional pot has an upper clutch at its bottom for engaging with a clutch 20. The functional pot and the frying pan 32 can be alternately placed on the support surface. In this embodiment, the cooking device is equipped with two different types of cookware: a functional pot with an upper clutch and a frying pan 32. The user can switch between the functional pot and the frying pan 32 on the support surface of the base according to their needs, thereby achieving different cooking functions. The functional pot can achieve different functions depending on the functional components connected to the upper clutch. For example, when the upper clutch of the cookware is connected to a frying knife, the functional pot is a frying pan 31 that can automatically fry vegetables; when the upper clutch of the cookware is connected to a stirring paddle, the functional pot is a food preparation pot that can automatically stir.

[0085] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
