Description

Technical Field

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

[0002] In related technologies, a stir-fry machine is an automatic cooking device that can automatically stir-fry and cook ingredients, greatly reducing people's cooking burden. In the design of a stir-fry machine, the mixing component is a key part, directly affecting the mixing effect and efficiency.

[0003] The mixing assembly includes a mixing motor, a mixing blade, and a drive motor. The mixing motor and the mixing blade are coupled and decoupled via a pair of couplers, which are in turn connected by the drive motor. A coupler is a mechanical device that transmits power. When the couplers are coupled, they transmit the power from the mixing motor to the mixing blade, thus mixing the food. When the couplers are decoupled, the mixing motor and the mixing blade are separated, facilitating cleaning and replacement of the mixing blade.

[0004] However, because the stirring component of the cooking machine is equipped with multiple motors, the structure of the stirring component is relatively complex, which increases the difficulty of maintenance and repair. Utility Model Content

[0005] The main objective of this invention is to provide a stirring assembly and a cooking appliance to solve the problem of the complex structure of stirring assemblies in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a stirring assembly is provided, comprising: a stirring structure, wherein a first coupler is disposed on the stirring structure; and a motor assembly, comprising a motor body, a motor shaft rotatably disposed on the motor body, a second coupler slidably connected to the motor shaft and capable of rotating with the motor shaft, and a limiting seat fixedly connected to the motor body, wherein the limiting seat is provided with a communicating moving guide portion and a rotating guide portion, the second coupler cooperating with the moving guide portion and the rotating guide portion respectively, and the second coupler having a coupling position coupled with the first coupler and a separation position separated from the first coupler; wherein, during the rotation of the motor shaft, the moving guide portion enables the second coupler to move between the coupling position and the separation position, or the rotating guide portion enables the second coupler to remain in the coupling position.

[0007] By applying the technical solution of this utility model, when the second coupler is in the coupling position, the second coupler rotates with the motor shaft and drives the first coupler to rotate, so that the motor shaft drives the stirring structure to rotate. Furthermore, when the motor body is working, the motor shaft rotates. During the rotation of the motor shaft, since the second coupler cooperates with the moving guide and the rotating guide respectively, it can both drive the second coupler to switch between the coupling and disengagement positions and drive the stirring structure to rotate. This eliminates the need for multiple motors, simplifying the structure of the stirring assembly, reducing maintenance and repair difficulties, and lowering costs. Therefore, the technical solution of this application effectively solves the problem of the complex structure of stirring assemblies in related technologies.

[0008] Furthermore, the second coupler is provided with a limiting protrusion protruding in its radial direction, a moving guide part is a moving guide channel, and a rotating guide part is a rotating guide channel communicating with the end of the moving guide channel. The limiting protrusion is guided and engaged with the moving guide channel and the rotating guide channel, respectively. During the rotation of the motor shaft, under the guiding engagement of the limiting protrusion on the second coupler and the moving guide channel, the second coupler and the limiting seat are linked, so that the second coupler moves between the coupling position and the separation position. When the limiting protrusion on the second coupler enters the rotating guide channel from the end of the moving guide channel, the second coupler moves from the separation position to the coupling position, and under the guiding engagement of the limiting protrusion and the rotating guide channel, the second coupler can be maintained in the coupling position.

[0009] Furthermore, the movable guide channel extends both axially and circumferentially along the limiting seat. This movable guide channel guides the limiting protrusion to move simultaneously along the axial and circumferential directions of the limiting seat, gradually transforming the movement of the limiting protrusion with the rotation of the motor shaft into movement along the axial direction of the limiting seat. This allows the movable guide channel to apply a reaction force to the limiting protrusion, thereby enabling the second coupler shaft to slide smoothly relative to the motor shaft.

[0010] Furthermore, the rotation guide channel extends circumferentially along the second coupler and is located at the end of the moving guide channel away from the motor shaft. In the above structure, the limiting protrusion on the second coupler can smoothly enter the rotation guide channel from the end of the moving guide channel. At this time, the second coupler moves from the separated position to the coupled position. Subsequently, the rotation guide channel guides the limiting protrusion to rotate circumferentially along the second coupler and can limit the rotation range of the limiting protrusion, so that the second coupler can be smoothly maintained in the coupled position while rotating with the motor shaft.

[0011] Furthermore, in order to make the structure of the stirring assembly compact, the limiting seat is provided with a first receiving hole for accommodating the second coupler, and the moving guide and the rotating guide are both provided on the inner side wall of the limiting seat.

[0012] Furthermore, in order to facilitate the second coupler to be slidably connected to the motor shaft and to rotate with the motor shaft, the motor assembly also includes a bushing sleeve fitted on the motor shaft and engaging with the motor shaft to prevent rotation, and the second coupler is slidably connected to the bushing sleeve.

[0013] Furthermore, a limiting channel is provided on the bushing, and a limiting protrusion is provided on the second coupler. The limiting channel extends along the rotation axis of the motor shaft, and the limiting protrusion slides in conjunction with the limiting channel. In the above structure, during the rotation of the motor shaft, the limiting channel can restrict the limiting protrusion, preventing the limiting protrusion from rotating relative to the bushing, facilitating the sliding of the limiting protrusion relative to the motor shaft, and the limiting protrusion can cooperate with the moving guide to allow the second coupler to move between the coupling position and the disengagement position.

[0014] Furthermore, the inner bore of the bushing includes a second receiving hole for accommodating the second coupler and a synchronization hole for engaging with the motor shaft to prevent rotation. A limiting channel is provided on the inner sidewall of the bushing. The aforementioned bushing can simultaneously accommodate the motor shaft and the second coupler, making the structure of the stirring assembly compact.

[0015] Furthermore, in order to minimize the impact of the length limitation of the rotation guide on the rotation range of the stirring structure, the first coupler includes a first tooth, and the second coupler includes a second tooth that can couple with the first tooth. The transmission ratio between the first tooth and the second tooth is greater than 0 and less than or equal to 1.

[0016] According to another aspect of this utility model, a cooking appliance is provided, including a pot body, a lid covering the pot body, and a stirring assembly disposed on the pot body, wherein the stirring assembly is the aforementioned stirring assembly; the pot body includes an outer shell and an inner pot removably disposed within the outer shell, the stirring structure is rotatably disposed on the inner pot, and a motor assembly is disposed on the outer shell, wherein the rotation axis of the motor shaft extends laterally; and / or, an opening / closing detection device is disposed between the lid and the pot body, the opening / closing detection device including a trigger and a sensor capable of sensing and cooperating with the trigger, one of the trigger and the sensor being disposed on the lid, and the other of the trigger and the sensor being disposed on the pot body. Thus, when the trigger and the sensor are in sensing and cooperating, real-time detection can be performed when the lid is closed. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

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.

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.

[0034] like Figures 1 to 4 and Figure 6As shown, this application provides a stirring assembly, an embodiment of which includes a stirring structure 10 and a motor assembly 20. A first coupler 11 is provided on the stirring structure 10. The motor assembly 20 includes a motor body 27, a motor shaft 21 rotatably mounted on the motor body 27, a second coupler 23 slidably connected to the motor shaft 21 and capable of rotating with the motor shaft 21, and a limiting seat 26 fixedly connected to the motor body 27. The limiting seat 26 is provided with a communicating moving guide portion 261 and a rotating guide portion 262. The second coupler 23 cooperates with both the moving guide portion 261 and the rotating guide portion 262, and has a coupling position that is coupled with the first coupler 11 and a separation position that is separated from the first coupler 11. During the rotation of the motor shaft 21, the moving guide portion 261 enables the second coupler 23 to move between the coupling position and the separation position, or the rotating guide portion 262 enables the second coupler 23 to remain in the coupling position. When the second coupler 23 moves from the coupling position to the separation position, it is convenient to clean and replace the stirring structure 10.

[0035] Applying the technical solution of this embodiment, when the second coupler 23 is in the coupled position, the second coupler 23 rotates with the motor shaft 21 and drives the first coupler 11 to rotate, so that the motor shaft 21 drives the stirring structure 10 to rotate. Furthermore, when the motor body 27 is working, the motor shaft 21 rotates. During the rotation of the motor shaft 21, since the second coupler 23 cooperates with the moving guide 261 and the rotating guide 262 respectively, it can both drive the second coupler 23 to switch between the coupled and separated positions and drive the stirring structure 10 to rotate. This eliminates the need for multiple motors, simplifying the structure of the stirring assembly, reducing maintenance and repair difficulties, and lowering costs. Therefore, the technical solution of this embodiment effectively solves the problem of the complex structure of stirring assemblies in related technologies.

[0036] In this embodiment, when the motor shaft 21 rotates along the first rotation direction, the second coupler 23 cooperates with the moving guide 261, driving the second coupler 23 from the separated position to the coupled position. When the motor shaft 21 rotates along the second rotation direction opposite to the first rotation direction, the second coupler 23 still cooperates with the moving guide 261, driving the second coupler 23 from the coupled position to the separated position. When the motor shaft 21 rotates along the first or second rotation direction, the second coupler 23 cooperates with the rotation guide 262, and the second coupler 23 remains in the coupled position, enabling the stirring structure 10 to rotate together.

[0037] It should be noted that the first rotation direction mentioned above can be clockwise or counterclockwise.

[0038] In this embodiment, the motor body 27 is drivenly connected to the motor shaft 21. When the motor body 27 is powered, the motor body 27 controls the motor shaft 21 to rotate in a first rotation direction or a second rotation direction. The motor assembly 20 also includes a motor bracket for mounting the motor body 27, which is fastened to the housing 41 described below by screws.

[0039] It should be noted that the limiting seat 26 of this application can be directly fixedly connected to the motor body 27, or indirectly fixedly connected to the outer casing 41 through the motor body 27.

[0040] In this embodiment, the first coupler 11 is equipped with a magnet, which is used for in-situ detection. The second coupler 23 has a scalloped tooth pattern, and the first coupler 11 has a scalloped tooth hole. When the scalloped tooth is inserted into the scalloped tooth hole, the second coupler 23 is coupled with the first coupler 11. When the scalloped tooth is disengaged from the scalloped tooth hole, the second coupler 23 is separated from the first coupler 11.

[0041] like Figure 2 , Figures 4 to 6 As shown, the second coupler 23 is provided with a limiting protrusion protruding in its radial direction. The moving guide part 261 is a moving guide channel, and the rotating guide part 262 is a rotating guide channel communicating with the end of the moving guide channel. The limiting protrusion 25 is guided and engaged with the moving guide channel and the rotating guide channel, respectively. During the rotation of the motor shaft 21, under the guiding engagement of the limiting protrusion on the second coupler 23 and the moving guide channel, the second coupler 23 is linked with the limiting seat, so that the second coupler 23 moves between the coupling position and the separation position. When the limiting protrusion on the second coupler 23 enters the rotating guide channel from the end of the moving guide channel, the second coupler 23 moves from the separation position to the coupling position, and under the guiding engagement of the limiting protrusion and the rotating guide channel, the second coupler 23 can be maintained in the coupling position.

[0042] like Figure 2 , Figures 4 to 6 As shown, the moving guide channel extends both axially and circumferentially along the limiting seat 26. This moving guide channel guides the limiting protrusion 25 to move both axially and circumferentially along the limiting seat 26, and gradually transforms the movement of the limiting protrusion 25 along the rotation of the motor shaft 21 into movement along the axial direction of the limiting seat 26. This allows the moving guide channel to apply a reaction force to the limiting protrusion 25, thereby enabling the second coupler 23 shaft to slide smoothly relative to the motor shaft 21.

[0043] It should be noted that the "axial and circumferential directions of the limiting seat 26" in the context of the moving guide channel extending simultaneously along the axial and circumferential directions of the limiting seat 26 refer to the direction of an inclined line on the side wall of the limiting seat 26, which can be a straight line or a spiral line.

[0044] like Figure 2 , Figures 4 to 6 As shown, the rotation guide channel extends circumferentially along the second coupler 23 and is located at the end of the moving guide channel away from the motor shaft 21. In the above structure, the limiting protrusion 25 on the second coupler 23 can smoothly enter the rotation guide channel from the end of the moving guide channel. At this time, the second coupler 23 moves from the separation position to the coupling position. Subsequently, the rotation guide channel guides the limiting protrusion 25 to rotate circumferentially along the second coupler 23 and limits the rotation range of the limiting protrusion 25, so that the second coupler 23 can smoothly remain in the coupling position while rotating with the motor shaft 21. Specifically, the ends of the moving guide channel and the rotation limiting channel are connected. In this way, when the motor shaft 21 rotates in the first rotation direction, the second coupler 23 is driven to rotate in the first rotation direction through the bushing 22. And because the limiting protrusion 25 moves within the moving guide channel, the moving guide part 261 can easily move the second coupler 23 from the separation position to the coupling position. When the limiting protrusion 25 moves from the moving guide channel into the rotating guide channel, the rotating guide 262 keeps the second coupler 23 in the coupled position, and the motor shaft 21 continues to rotate in the first rotation direction, driving the stirring structure 10 to rotate together. When the motor shaft 21 rotates in the second rotation direction opposite to the first rotation direction, the limiting protrusion 25 moves along the rotating guide channel and can move into the moving guide channel, thereby moving the second coupler 23 from the coupled position to the separated position. In this way, when the motor shaft 21 rotates in the first or second rotation direction, the limiting protrusion 25 can move within the moving guide channel and the rotating guide channel. Since the ends of the moving guide channel and the rotating guide channel are connected, the moving distance of the limiting protrusion 25 is relatively long, which ensures that the second coupler 23 is kept in the coupled position or can switch between the separated position and the coupled position.

[0045] like Figure 2 , Figures 4 to 6 As shown, to ensure a compact structure for the stirring assembly, the limiting seat 26 is provided with a first receiving hole 263 to accommodate the second coupler 23. Furthermore, for ease of manufacturing, both the moving guide 261 and the rotating guide 262 are located on the inner sidewall of the limiting seat 26. Specifically, the first receiving hole 263 is preferably a circular hole. The first receiving hole 263 can also accommodate the bushing 22 mentioned below.

[0046] It should be noted that the moving guide 261 and the rotating guide 262 can be through slots that penetrate the radial direction of the limiting seat 26, or they can be ordinary slots that do not penetrate the radial direction of the limiting seat 26.

[0047] like Figure 2 , Figures 4 to 6 As shown, in order to facilitate the second coupler 23 to be slidably connected to the motor shaft 21 and to rotate with the motor shaft 21, the motor assembly 20 also includes a bushing 22 sleeved on the motor shaft 21 and engaged with the motor shaft 21 to prevent rotation, and the second coupler 23 is slidably connected to the bushing 22.

[0048] like Figure 2 , Figures 4 to 6 As shown, a limiting channel 221 is provided on the bushing 22, and a limiting protrusion 25 is provided on the second coupler 23. The limiting channel 221 extends along the rotation axis L of the motor shaft 21, and the limiting protrusion 25 slides in conjunction with the limiting channel 221. During the rotation of the motor shaft 21 (i.e., when the motor shaft 21 rotates along the first rotation direction or the second rotation direction), the limiting protrusion 25 moves within the limiting channel 221. The limiting channel 221 can restrict the limiting protrusion 25, preventing the limiting protrusion 25 from rotating relative to the bushing 22, facilitating the sliding of the limiting protrusion 25 relative to the motor shaft 21. Furthermore, the limiting protrusion 25 cooperates with the moving guide 261, allowing the second coupler 23 to move between the coupling position and the disengagement position.

[0049] In this embodiment, after the motor shaft 21, the second coupler 23, and the bushing 22 are assembled together, the limiting protrusion 25 is located within the limiting channel 221. The limiting protrusion 25 passes through the limiting channel 221 and is located within the moving guide channel, so that the second coupler 23 can cooperate with the moving guide 261. The limiting protrusion 25 passes through the limiting channel 221 and is located within the rotation guide channel, so that the second coupler 23 can cooperate with the rotation guide 262.

[0050] Specifically, there are three limiting protrusions 25 arranged at circumferential intervals along the second coupler 23, and there are three corresponding moving guides 261, limiting channels 221 and rotating guides 262.

[0051] In this embodiment, the length of the limiting channel 221 limits the distance the limiting protrusion 25 can move in the moving direction of the second coupler 23. The length of the rotation guide 262 limits the distance the limiting protrusion 25 can move in the circumferential direction of the second coupler 23. At the same time, the length of the rotation guide 262 also limits the rotation range of the stirring structure 10.

[0052] like Figure 2 , Figures 4 to 6As shown, the inner hole of the bushing 22 includes a second receiving hole 222 for accommodating the second coupler 23 and a synchronization hole 223 for engaging with the motor shaft 21 to prevent rotation. Thus, the bushing 22 can simultaneously accommodate the motor shaft 21 and the second coupler 23, resulting in a compact structure for the stirring assembly. Furthermore, when the bushing 22 is driven by the motor shaft 21, the synchronization hole 223 facilitates the synchronous rotation of the bushing 22 with the motor shaft 21. For ease of manufacturing, a limiting channel 221 is provided on the inner wall of the bushing 22.

[0053] Specifically, the motor shaft 21 is preferably a D-shaped shaft, and the synchronizing hole 223 is preferably a D-shaped hole that mates with the D-shaped shaft. The second receiving hole 222 is preferably a round hole.

[0054] like Figure 2 , Figure 4 and Figure 7 As shown, to ensure that the rotation range of the stirring structure 10 is no longer limited by the length of the rotation guide 262, the first coupler includes a first toothed member 12, and the second coupler includes a second toothed member 24 capable of coupling with the first toothed member 12. The transmission ratio between the first toothed member 12 and the second toothed member 24 is greater than 0 and less than 1. Thus, when the first toothed member 12 rotates at a small angle, the second toothed member 24 can rotate at a larger angle, thereby increasing the number of stirring revolutions of the stirring structure 10 and avoiding the limitation imposed by the length of the rotation guide 262.

[0055] Of course, in other embodiments, the transmission ratio between the first gear 12 and the second gear 24 is equal to 1.

[0056] Specifically, the first gear 12 includes a large gear, and the second gear 24 includes a small gear, wherein the number of teeth of the large gear is greater than the number of teeth of the small gear.

[0057] This application also provides a cooking appliance, an embodiment of which includes a pot body 40 and a stirring assembly disposed on the pot body 40, the stirring assembly being the stirring assembly described above.

[0058] This application also provides a cooking appliance, an embodiment of which includes a pot body 40, a lid 50 covering the pot body 40, and a stirring assembly disposed on the pot body 40, the stirring assembly being the aforementioned stirring assembly. Since the aforementioned stirring assembly can solve the problem of the complex structure of stirring assemblies in related technologies, the cooking appliance including this stirring assembly can solve the same technical problem.

[0059] like Figure 2 and Figure 8As shown, the pot body 40 includes an outer shell 41 and an inner pot 42 removably disposed within the outer shell 41. A stirring structure 10 is rotatably disposed on the inner pot 42, and a motor assembly 20 is disposed on the outer shell 41, wherein the rotation axis L of the motor shaft 21 extends laterally. In other embodiments, the rotation axis L of the motor shaft 21 extends vertically.

[0060] like Figure 2 and Figure 8 As shown, an opening / closing detection device is provided between the lid 50 and the pot body 40. This device includes a trigger 51 and a sensor 52 that engages with the trigger 51. The trigger 51 is located on the lid 50, and the sensor 52 is located on the pot body 40. The lid 50 includes a bottom plate and an upper cover connected to the edge of the bottom plate. The bottom plate forms the trigger 51. The sensor 52 is preferably a mechanical microswitch, with its sensing button protruding from the top surface of the outer shell 41. When the lid 50 is flipped to close, the bottom plate directly presses the sensing button. The closing of the microswitch triggers an electrical signal on the control panel of the cooking appliance, thus enabling real-time detection of the lid closure.

[0061] Of course, in other embodiments, the sensing element 52 is disposed on the cover 50 and the trigger element 51 is disposed on the pot body 40.

[0062] In this embodiment, the cooking appliance is a stir-fry machine; in other embodiments, the cooking appliance is a dough mixer, a multi-functional pot, or a soy milk maker.

[0063] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" 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 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 a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0064] 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.

[0065] 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 cannot be construed as limiting the scope of protection of this utility model.
