Description

Technical Field

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

[0002] The pot assembly in the related technology includes: a pot body, a stirring structure, a drive assembly, and a unlocking structure. The stirring structure is rotatably mounted on the pot body. The drive assembly includes a drive member mounted on the pot body and a transmission mechanism mounted on the pot body, the transmission mechanism enabling the drive member and the stirring structure to be connected or disconnected. The unlocking structure is movably mounted on the pot body and has a downwardly extending drive rod, the drive rod enabling the transmission mechanism to disconnect the drive member and the stirring structure.

[0003] When the aforementioned drive component requires maintenance, the limited range of motion of the drive rod restricts the disassembly direction of the transmission mechanism. Therefore, the unlocking structure must first be removed to release the interference from the drive rod before the transmission mechanism can be disassembled, and only then can the drive component be removed. This makes the disassembly process complex and the maintenance efficiency low. Utility Model Content

[0004] The main purpose of this utility model is to provide a pot body assembly and cooking appliance to solve the problems of complex disassembly process and low maintenance efficiency of the drive components in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a pot body assembly is provided, comprising: a pot body; a stirring structure rotatably disposed on the pot body; a drive assembly including a protective shell detachably disposed on the pot body, a drive member disposed within the protective shell, and a transmission mechanism movably disposed on the protective shell, the transmission mechanism enabling the drive member and the stirring structure to be connected or disconnected; and an unlocking structure movably disposed on the pot body, capable of driving the transmission mechanism to disconnect the drive member and the stirring structure.

[0006] By applying the technical solution of this utility model, when the transmission mechanism connects the driving component and the stirring structure, the driving component can drive the stirring structure to rotate, thereby stirring the food inside the pot and achieving the stirring function. When the transmission mechanism disconnects the driving component and the stirring structure, the driving component separates from the stirring structure, and the stirring structure can be removed from the pot, facilitating the removal of food from the pot or cleaning the interior of the pot. When the driving component needs maintenance, the protective shell can be removed from the pot, and the transmission mechanism and driving component can be removed together with the protective shell. Then, the driving component inside the protective shell can be repaired, avoiding interference from the unlocking structure to the transmission mechanism, reducing the complexity of the driving component disassembly process, and improving the maintenance efficiency of the driving component. Therefore, the technical solution of this application effectively solves the problems of complex disassembly processes and low maintenance efficiency of driving components in related technologies.

[0007] Furthermore, the pot body includes a heat preservation cover and a container disposed inside the heat preservation cover. The stirring structure is rotatably mounted on the container, and the protective shell is detachably mounted on the heat preservation cover. Compared to the protective shell being fixed to the pot body, detachably mounting the protective shell on the heat preservation cover facilitates the maintenance of the drive components and improves the maintenance efficiency of the drive components.

[0008] Furthermore, the insulation cover includes a cover body and a connecting arm disposed on the outside of the cover body, with the protective shell detachably mounted on the connecting arm. The protective shell is mounted on the connecting arm, rather than being directly fixed to the container, thus reducing the space occupied by the drive components inside the container and facilitating independent disassembly and maintenance of the protective shell without affecting the normal use of the container.

[0009] Furthermore, the cooker body also includes a shell located outside the heat insulation cover and a base detachably connected to the bottom of the shell. The drive assembly is located between the shell and the heat insulation cover, and the unlocking structure is movably mounted on the shell. Thus, when repairing the drive assembly, the base is first removed from the bottom of the shell, the protective shell is removed from the heat insulation cover, and then the drive assembly can be moved horizontally a certain distance away from the heat insulation cover before being removed from the bottom of the shell.

[0010] Furthermore, the unlocking structure includes a drive rod movably mounted on the pot body and an operation key connected to the drive rod. The protective shell has clearance holes for the drive rod to pass through or move out. When the drive rod passes through the clearance holes, it can drive the transmission mechanism. The clearance hole design allows the drive rod of the unlocking structure to move freely, without being physically restricted by the protective shell. This allows the pressure of the operation key to be directly transmitted to the transmission mechanism, achieving rapid disconnection between the stirring structure and the drive component, thus improving the user's operating experience.

[0011] Furthermore, the protective shell includes a first shell portion and a second shell portion that are mated together, a drive component is sandwiched between the first shell portion and the second shell portion, and a transmission mechanism is movably mounted on the first shell portion and / or the second shell portion. Designing the protective shell as a first shell portion and a second shell portion facilitates the disassembly and inspection of the internal drive component and transmission mechanism. The mating design of the first shell portion and the second shell portion reduces changes to the overall structure of the equipment, while ensuring the protection of the drive component and the smooth transmission of the transmission mechanism.

[0012] Furthermore, the transmission mechanism includes a coupling movably disposed on the drive member and a transmission member that drives the coupling to move. The transmission member is movably disposed on the first housing and / or the second housing. The unlocking structure can drive the transmission member to push the coupling through the transmission member. The coupling can disconnect the drive member from the stirring structure.

[0013] Furthermore, the transmission mechanism includes a coupling movably mounted on the drive member and a swing member that pushes the coupling to move. The swing member is swingably mounted on the first housing and / or the second housing. The unlocking structure can drive the swing member to push the coupling, which can then disconnect the drive member from the stirring structure. Through the movement of the transmission member, the unlocking structure can effectively control the movement of the coupling, achieving automatic disconnection between the stirring structure and the drive member, reducing the complexity of manual operation by the user. At the same time, the movable design of the transmission member increases the flexibility and reliability of the transmission mechanism.

[0014] Furthermore, the stirring structure includes a stirring blade rotatably mounted on the pot body and a mating device connected to the stirring blade. A transmission mechanism allows the drive component and the mating device to be connected or disconnected. The transmission mechanism includes a coupling, a transmission component, and a swinging component. The coupling is movably mounted on the drive component, the transmission component is movably mounted on the protective shell and can drive the coupling to move, and the swinging component is oscillatingly mounted on the protective shell and can drive the transmission component to move. An unlocking structure can drive the swinging component to swing. Using the swinging motion of the swinging component to drive the coupling makes the transmission mechanism operate more smoothly, and the movement trajectory of the swinging component is easier to control, improving the accuracy and reliability of the transmission.

[0015] According to another aspect of the present invention, a cooking appliance is provided, including a pot body assembly, wherein the pot body assembly is the pot body assembly described above. Attached Figure Description

[0030] 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. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] like Figures 1 to 5 As shown, this application provides a pot body assembly, which includes a pot body 10, a stirring structure 20, a drive assembly 30, and an unlocking structure 50. The stirring structure 20 is rotatably mounted on the pot body 10. The drive assembly 30 includes a protective shell 31 detachably mounted on the pot body 10, a drive member 32 disposed within the protective shell 31, and a transmission mechanism 40 movably mounted on the protective shell 31. The transmission mechanism 40 enables the drive member 32 and the stirring structure 20 to be connected or disconnected. The unlocking structure 50 is movably mounted on the pot body 10 and can drive the transmission mechanism 40 to disconnect the drive member 32 and the stirring structure 20.

[0034] In the embodiment of the pot body assembly, when the transmission mechanism connects the driving component and the stirring structure, the driving component can drive the stirring structure to rotate, thereby stirring the food inside the pot body and achieving the stirring function. When the transmission mechanism disconnects the driving component and the stirring structure, the driving component separates from the stirring structure, and the stirring structure can be removed from the pot body for easy removal of food or cleaning of the pot body's interior. When maintenance of the driving component 32 is required, the protective shell 31 can be removed from the pot body 10, and the transmission mechanism 40 and the driving component 32 can be removed together with the protective shell 31. Then, the driving component 32 inside the protective shell 31 can be repaired, avoiding interference from the unlocking structure 50 to the transmission mechanism 40, reducing the complexity of the driving component disassembly process, and improving the maintenance efficiency of the driving component. Therefore, the technical solution of the embodiment of the pot body assembly effectively solves the problems of complex disassembly processes and low maintenance efficiency of driving components in related technologies. In this embodiment, the driving component is preferably a drive motor.

[0035] like Figures 1 to 5As shown, the pot body 10 includes a heat preservation cover 11 and a container 12 disposed inside the heat preservation cover 11. The stirring structure 20 is rotatably disposed on the container 12, and the protective shell 31 is detachably disposed on the heat preservation cover 11. Compared to the protective shell 31 being fixed to the pot body, detachably disposing of the protective shell 31 on the heat preservation cover 11 facilitates the maintenance of the drive component 32 and improves the maintenance efficiency of the drive component 32.

[0036] It should be noted that the detachable connection in this application is achieved through the connection of fasteners, specifically screws or bolts.

[0037] like Figures 5 to 7 As shown, the insulation cover 11 includes a cover body 111 and a connecting arm 112 disposed on the outside of the cover body 111. The protective shell 31 is detachably disposed on the connecting arm 112. The protective shell 31 is mounted on the connecting arm 112, rather than being directly fixed to the container 12. This reduces the space occupied by the drive assembly 30 inside the container 12, and facilitates the independent disassembly and maintenance of the protective shell 31 without affecting the normal use of the container 12.

[0038] like Figures 1 to 5 As shown, the pot body 10 also includes a shell 13 located outside the heat insulation cover 11 and a base 14 detachably connected to the bottom of the shell 13. The drive assembly 30 is located between the shell 13 and the heat insulation cover 11, and the unlocking structure 50 is movably mounted on the shell 13. Thus, when repairing the drive assembly 30, the base 14 is first removed from the bottom of the shell 13, the protective shell 31 is removed from the heat insulation cover 11, and then the drive assembly 30 can be moved horizontally a certain distance away from the heat insulation cover 11 before being removed from the bottom of the shell 13. Specifically, when the drive assembly 32 needs to be disassembled, the entire pot body assembly is first inverted, with the bottom of the shell 13 facing upwards, then the base 14 is removed, and then the drive assembly 30 is disassembled and removed.

[0039] like Figures 1 to 5 As shown, the unlocking structure 50 includes a drive rod 51 movably mounted on the pot body 10 and an operation key 52 connected to the drive rod 51. The protective shell 31 has a clearance hole 33 for the drive rod 51 to pass through or move out. When the drive rod 51 passes through the clearance hole 33, it can drive the transmission mechanism 40 to move. The design of the clearance hole 33 allows the drive rod 51 of the unlocking structure 50 to move freely without being physically restricted by the protective shell 31. This allows the pressure of the operation key 52 to be directly transmitted to the transmission mechanism 40, achieving rapid disconnection between the stirring structure 20 and the drive component 32, thus improving the user's operating experience. The operation key 52 is preferably a button.

[0040] like Figures 5 to 7As shown, the protective shell 31 includes a first shell portion 311 and a second shell portion 312 that are mated together. A drive member 32 is sandwiched between the first shell portion 311 and the second shell portion 312. A transmission mechanism 40 is movably mounted on the first shell portion 311 and / or the second shell portion 312. Designing the protective shell 31 as a first shell portion 311 and a second shell portion 312 facilitates the disassembly and inspection of the internal drive member 32 and transmission mechanism 40. The mating design of the first shell portion 311 and the second shell portion 312 reduces changes to the overall structure of the equipment while ensuring the protection of the drive member 32 and the smooth transmission of the transmission mechanism 40.

[0041] like Figures 1 to 5 and Figure 7 As shown, the transmission mechanism 40 includes a coupling 41 movably mounted on the drive member 32 and a transmission member 42 that pushes the coupling 41 to move. The transmission member 42 is movably mounted on the first housing portion 311 and the second housing portion 312. The unlocking structure 50 can drive the transmission member 42 to push the coupling 41, which in turn can disconnect the drive member 32 from the stirring structure 20. Through the movement of the transmission member 42, the unlocking structure 50 can effectively control the movement of the coupling 41, achieving automatic disconnection between the stirring structure 20 and the drive member 32, reducing the complexity of manual operation by the user. At the same time, the movable design of the transmission member 42 increases the flexibility and reliability of the transmission mechanism 40.

[0042] A return spring is fitted on the drive component 32. The return spring applies an elastic force to the coupling 41. When the unlocking structure 50 is not operated by the user, the return spring pushes the coupling 41 to connect the coupling 41 with the stirring structure 20.

[0043] In other embodiments, the transmission member 42 is movably disposed on the first housing portion 311 or the second housing portion 312.

[0044] like Figures 1 to 5 and Figure 7 As shown, the transmission mechanism 40 includes a coupling 41 movably mounted on the drive member 32 and a swing member 43 that pushes the coupling 41 to move. The swing member 43 is swingably mounted on the first housing portion 311 and the second housing portion 312. The unlocking structure 50 can drive the swing member 43 to push the coupling 41, which can disconnect the drive member 32 from the stirring structure 20. Using the swinging motion of the swing member 43 to push the coupling 41 makes the transmission mechanism 40 operate more smoothly, and the movement trajectory of the swing member 43 is easier to control, improving the accuracy and reliability of the transmission. The swing member 43 is preferably a swing lever.

[0045] In other embodiments, the swing member 43 is swingably disposed on the first housing portion 311 or the second housing portion 312.

[0046] In this application, a first guide portion 421 is provided on the first shell portion 311 and the second shell portion 312, and a second guide portion 422 is provided on the transmission member 42 to guide and cooperate with the first guide portion 421. The first guide portion 421 is a transverse guide groove, and the second guide portion 422 is a transverse guide rib to guide and cooperate with the transverse guide groove. The transmission member 42 is preferably a transmission cylinder.

[0047] In other embodiments, a first guide portion 421 is provided on the first housing portion 311 or the second housing portion 312, and a second guide portion 422 is provided on the transmission member 42 to guide and cooperate with the first guide portion 421.

[0048] like Figures 1 to 5 As shown, the stirring structure 20 includes a stirring blade 21 rotatably mounted on the pot body 10 and a mating device 22 connected to the stirring blade 21. The transmission mechanism 40 enables the drive component 32 and the mating device 22 to be connected or disconnected. The transmission mechanism 40 includes a coupling 41, a transmission component 42, and a swinging component 43. The coupling 41 is movably mounted on the drive component 32, the transmission component 42 is movably mounted on the protective shell 31 and can push the coupling 41 to move, and the swinging component 43 is swingably mounted on the protective shell 31 and can drive the transmission component 42 to move. The unlocking structure 50 can drive the swinging component 43 to swing. The coordinated operation of the coupling 41, the transmission component 42, and the swinging component 43 ensures a stable connection or disconnection between the stirring blade 21 and the drive component 32, improving stirring efficiency and the ease of maintenance of the drive component. At the same time, the independent movement and swinging design of each component reduces the risk of the entire system failing due to the failure of a single component and enhances the stability of the pot body assembly.

[0049] Specifically, the coupling 41 is provided with a plum blossom-shaped protrusion, and the mating device 22 is provided with a plum blossom-shaped groove that engages with the plum blossom-shaped protrusion. When the plum blossom-shaped protrusion engages with the plum blossom-shaped groove, the drive member 32 and the mating device 22 are connected; when the plum blossom-shaped protrusion disengages from the plum blossom-shaped groove, the drive member 32 and the mating device 22 are disconnected.

[0050] This application also provides a cooking appliance, an embodiment of which includes a pot body assembly, which is the pot body assembly described above. Because the aforementioned pot body assembly can solve the problems of complex disassembly processes and low maintenance efficiency of drive components in related technologies, the cooking appliance including this pot body assembly can solve the same technical problems.

[0051] The cooking appliance is preferably a stir-fry machine. In other embodiments, the cooking appliance is a dough mixer, a whipping machine, a soy milk maker, a blender, or a multi-functional pot.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
