Description

Technical Field

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

[0002] The cooking utensil includes a pot body, a lid, and a handle. The pot body has a welt, and the lid has a locking mechanism that engages with the welt. The lid has a handle on its top surface, which the user can use to rotate the lid relative to the pot body, allowing the locking mechanism on the lid to engage or disengage with the pot body.

[0003] In related technologies, cooking utensils have handles located on the top surface of the lid. This increases the overall height of the cooking utensil, making it more difficult to store. Utility Model Content

[0004] The main purpose of this utility model is to provide a cooking utensil that solves the problem in related technologies where the handle increases the overall height of the cooking utensil, making it inconvenient to store.

[0005] To achieve the above objectives, this utility model provides a cooking utensil, comprising: a pot body, a lid, an operating structure, a lower transmission structure, and an upper transmission structure. The pot body is provided with a "pot tooth" (or "pot teeth"). The lid is placed on the pot body and includes a lid body main body and a first locking mechanism disposed on the lid body main body. The first locking mechanism is movably disposed relative to the lid body main body and has a first unlocking position separated from the pot tooth and a first locking position engaged with the pot tooth. The operating structure is located in the front-rear direction of the pot body and is movable or swingable on the pot body. The lower transmission structure is rotatably disposed on the pot body about the vertical direction of the pot body. The upper transmission structure is rotatably disposed on the lid body main body. When the operating structure moves or swings, it drives the lower transmission structure to rotate, thereby driving the upper transmission structure to rotate, so that the upper transmission structure causes the first locking mechanism to switch between a first unlocking position and a first locking position.

[0006] By applying the technical solution of this utility model, the user can operate the operating structure on the pot body to drive the upper transmission structure through the lower transmission structure, thereby enabling the first locking mechanism to separate from or engage with the pot teeth. In this way, the user can drive the first locking mechanism to separate from or engage with the pot teeth by operating the operating structure on the pot body, avoiding the need for a handle on the top surface of the lid to drive the engaging structure to engage or disengage from the pot body, thus reducing the overall height of the cooking appliance and facilitating its storage. Furthermore, the operation structure moves or swings in the front-to-back direction of the pot body to drive the lower transmission structure, further reducing the space occupied by the operation structure in the height direction, further lowering the overall height of the cooking appliance. Therefore, the technical solution of this application effectively solves the problem in related technologies where handles increase the overall height of the cooking appliance, making it inconvenient to store it.

[0007] Furthermore, the operating structure includes a movable component movably mounted on the pot body and a first driving component movably mounted on the pot body. The movable component drives the lower transmission structure to rotate via the first driving component. The driving between the movable component and the first driving component is reliable, allowing the user to move the movable component to move the first driving component.

[0008] Furthermore, the moving component is provided with a first insertion part, and the first driving component is provided with a second insertion part. Through the insertion and engagement of the first and second insertion parts, the moving component and the first driving component can move synchronously. The first and second insertion parts have simple structures, are easy to process and assemble, and provide reliable transmission.

[0009] Furthermore, the first insertion part is one of the insertion slot and the insertion block, and the second insertion part is the other of the insertion slot and the insertion block. The above arrangement ensures reliable transmission and facilitates the insertion and engagement of the first and second insertion parts.

[0010] Furthermore, the operating structure includes a swinging member oscillating on the pot body and a second driving member movably mounted on the pot body. The swinging member drives the lower transmission structure to rotate via the second driving member. The driving of the swinging member and the second driving member is reliable, allowing the user to easily move the second driving member by driving it to swing.

[0011] Furthermore, the swing member is equipped with a drive arm, and the second drive member is equipped with a drive groove for the drive arm to insert into. The drive groove includes a front groove wall and a rear groove wall along the front-rear direction of the pot body. When the drive arm pushes against the front groove wall, the first locking mechanism switches from a first locked position to a first unlocked position through the transmission cooperation of the lower and upper transmission structures. When the drive arm pushes against the rear groove wall, the first locking mechanism switches from a first unlocked position to a first locked position through the transmission cooperation of the lower and upper transmission structures. The structure of the drive arm and drive groove is simple, the transmission is reliable, and the transmission cooperation between the swing member and the second drive member is convenient.

[0012] Furthermore, the lower transmission structure includes a lower gear and a lower coupling member connected to the lower gear. The operating structure is provided with a first tooth that mates with the lower gear. The upper transmission structure includes an upper gear and an upper coupling member connected to the upper gear. The upper gear is driven to connect with the first locking mechanism, and the upper coupling member is coupled to or decoupled from the lower coupling member. In this way, when the user drives the operating structure, it can move the first tooth to drive the lower gear and the lower coupling member to rotate.

[0013] Furthermore, a driven gear is provided on the pot body, and a second toothed part is provided on the operating structure to cooperate with the driven gear. The axis of the driven gear is parallel to the vertical direction of the pot body. The driven gear makes the movement or oscillation of the operating structure smoother. The above arrangement facilitates the movement of the second toothed part in a direction at an angle to the vertical direction of the pot body.

[0014] Furthermore, the cooking appliance also includes a swinging structure that can be oscillatingly mounted on the lid body. The swinging structure is driven and cooperates with the upper transmission structure. The lid body is also provided with an arc-shaped hole, and the swinging structure is provided with a drive elongated hole corresponding to the arc-shaped hole. The first locking mechanism is provided with a drive post passing through the arc-shaped hole and the drive elongated hole. The upper transmission structure drives the swinging structure to swing, so that the drive elongated hole drives the drive post to swing, thereby causing the first locking mechanism to switch between a first unlocked position and a first locked position. In this way, when the upper transmission structure rotates on the lid body, it can drive the drive elongated hole on the swinging structure to swing, thereby driving the drive post extending into the drive elongated hole to swing, and the drive post drives the first locking mechanism to switch between the first unlocked position and the first locked position.

[0015] Furthermore, the cooking appliance also includes a second locking mechanism, which is movably mounted on the pot body. This second locking mechanism has a second locking position to lock the lid onto the pot body and a second unlocking position to unlock the lid and allow it to be opened from the pot body. The operating structure includes a pusher; when the first locking mechanism is in the first unlocking position and the second locking mechanism is in the second locking position, the pusher engages with the second locking mechanism to switch the second locking mechanism from the second locked position to the second unlocking position. The pusher facilitates user operation by allowing the second locking mechanism to switch from the second locked position to the second unlocking position via the operating structure, making operation simple and quick and improving the user experience.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0040] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as 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.

[0041] like Figures 1 to 12 As shown, to achieve the above objectives, this application provides a cooking utensil. Embodiment 1 of the cooking utensil includes: a pot body, a lid, an operating structure, a lower transmission structure, and an upper transmission structure. The pot body is provided with a toothed edge 121. The lid covers the pot body and includes a lid body main body 21 and a first locking mechanism 22 disposed on the lid body main body 21. The first locking mechanism 22 is movably disposed relative to the lid body main body 21 and has a first unlocking position separated from the toothed edge 121 and a first locking position engaged with the toothed edge 121. The operating structure is located in the front-rear direction of the pot body and is movable or swingable on the pot body. The lower transmission structure is rotatably disposed on the pot body in the vertical direction around the pot body. The upper transmission structure is rotatably disposed on the lid body main body 21. When the operating structure moves or swings, it drives the lower transmission structure to rotate, thereby driving the upper transmission structure to rotate, so that the upper transmission structure drives the first locking mechanism 22 to switch between the first unlocking position and the first locking position.

[0042] By operating the operating structure on the pot body, the user can drive the upper transmission structure via the lower transmission structure, thereby enabling the first locking mechanism 22 to separate from or engage with the pot teeth 121. This allows the user to drive the first locking mechanism 22 to separate from or engage with the pot teeth 121 through the operating structure on the pot body, avoiding the need for a handle on the top surface of the lid to drive the engagement or disengagement of the pot body. This reduces the overall height of the cooking appliance, facilitating its storage. Furthermore, the operation structure's movement or swinging in the pot body's front-to-back direction to drive the lower transmission structure further reduces the space occupied by the operation structure in the height direction, further lowering the overall height of the cooking appliance. Therefore, the technical solution of Embodiment 1 effectively solves the problem in related technologies where handles increase the overall height of the cooking appliance, making it inconvenient to store it.

[0043] It should be noted that the front-to-back direction of the pot body refers to the side of the cooking utensil facing the user when using it, which is the front side, and the side away from the user, which is the back side, measured in the direction from front to back. The vertical direction of the pot body refers to the vertical direction or any direction within 30° of the vertical direction. The swing angle of the operating mechanism is less than or equal to 90°.

[0044] like Figures 1 to 9 As shown, in Embodiment 1, the operating structure includes a movable component 31 movably mounted on the pot body and a first driving component 32 movably mounted on the pot body. The movable component 31 drives the lower transmission structure to rotate via the first driving component 32. The driving between the movable component 31 and the first driving component 32 is reliable, allowing the user to move the movable component 31 to move the first driving component 32. The movable mounting of the operating structure on the pot body simplifies its installation and facilitates processing.

[0045] like Figures 1 to 9 As shown, in Embodiment 1, the moving member 31 is provided with a first insertion portion, and the first driving member 32 is provided with a second insertion portion. The moving member 31 and the first driving member 32 move synchronously through the insertion and engagement of the first and second insertion portions. The first and second insertion portions have simple structures, are easy to process and assemble, and provide reliable transmission, facilitating the synchronous movement of the moving member 31 and the first driving member 32.

[0046] like Figures 1 to 9 As shown, in Embodiment 1, the first insertion part is an insertion block 311, and the second insertion part is an insertion groove 321. The insertion block 311 and the insertion groove 321 have simple structures, are easy to process, have reliable transmission, and facilitate the insertion and engagement of the first insertion part and the second insertion part.

[0047] In other embodiments, the first insertion part is an insertion slot 321, and the second insertion part is an insertion block 311.

[0048] The difference between Embodiment 2 and Embodiment 1 in this application lies in the different ways the operating structure moves on the pot body. In Embodiment 1, the operating structure is movably mounted on the pot body. In Embodiment 2, the operating structure is swingably mounted on the pot body.

[0049] like Figures 10 to 12 As shown, in Embodiment 2, the operating structure includes a swinging member 33 oscillatingly mounted on the pot body and a second driving member 34 movably mounted on the pot body. The swinging member 33 drives the lower transmission structure to rotate via the second driving member 34. The driving of the swinging member 33 and the second driving member 34 is reliable, allowing the user to swing the second driving member 34 to move it. The oscillating mounting of the operating structure on the pot body makes its installation on the pot body more stable and reliable.

[0050] like Figures 10 to 12 As shown, in Embodiment 2, the swing member 33 is provided with a drive arm 331, and the second drive member 34 is provided with a drive groove 341 for the drive arm 331 to be inserted. The drive groove 341 includes a front groove wall 342 and a rear groove wall 343 along the front-rear direction of the pot body. When the drive arm 331 pushes against the front groove wall 342, the first locking mechanism 22 is switched from the first locked position to the first unlocked position through the transmission cooperation of the lower transmission structure and the upper transmission structure. When the drive arm 331 pushes against the rear groove wall 343, the first locking mechanism 22 is switched from the first unlocked position to the first locked position through the transmission cooperation of the lower transmission structure and the upper transmission structure. The structure of the drive arm 331 and the drive groove 341 is simple, the transmission is reliable, and the transmission cooperation between the swing member 33 and the second drive member 34 is convenient. In this way, the user can swing the swinging member 33 so that the drive arm 331 drives the lower transmission structure and the upper transmission structure through the drive groove 341, thereby driving the first locking mechanism 22 to switch between the first unlocking position and the first locking position, so as to facilitate the separation and engagement of the first locking mechanism 22 with the tooth 121.

[0051] like Figures 1 to 12 As shown, the lower transmission structure includes a lower gear 51 and a lower coupling member 52 connected to the lower gear 51. The operating structure is provided with a first tooth 35 that meshes with the lower gear 51. The upper transmission structure includes an upper gear 41 and an upper coupling member 42 connected to the upper gear 41. The upper gear 41 is drivenly connected to the first locking mechanism 22. The upper coupling member 42 is coupled to or decoupled from the lower coupling member 52. Thus, when the user drives the operating structure, it can move the first tooth 35 to rotate the lower gear 51 and the lower coupling member 52. When the lower coupling member 52 is coupled to the upper coupling member 42, the rotation of the lower coupling member 52 can drive the upper coupling member 42 to rotate, so that the upper gear 41 rotates and drives the first locking mechanism 22 to switch between the first unlocked position and the first locked position, so as to facilitate the separation and engagement of the first locking mechanism 22 with the jaw 121. When the lower coupling member 52 is coupled to the upper coupling member 42, it is convenient for the operating structure to transmit the driving force to the first locking mechanism 22 through the transmission of the lower coupling member 52 and the upper coupling member 42. When the lower coupling member 52 is separated from the upper coupling member 42, the lid can be easily opened from the pot body. The transmission engagement between the lower gear 51 and the first tooth 35, and the drive connection between the upper gear 41 and the first locking mechanism 22, have a simple structure, reliable transmission, and can transmit a large driving force.

[0052] In Embodiment 1, when the lid is placed on the pot body, the upper coupling member 42 is coupled to the lower coupling member 52, so that the operating structure can be driven through the lower coupling member 52 and the upper coupling member 42. When the lid is opened from the pot body, the upper coupling member 42 and the lower coupling member 52 can be separated to facilitate the separation of the lid from the pot body.

[0053] like Figures 1 to 12As shown, a driven gear 13 is provided on the pot body, and a second tooth 36 that meshes with the driven gear 13 is also provided on the operating structure. The driven gear 13 and the second tooth 36 have a simple structure, reliable transmission, and can transmit a large driving force. The driven gear 13 makes the movement or oscillation of the operating structure smoother. The axis of the driven gear 13 is parallel to the vertical direction of the pot body, so that the second tooth 36 can move in a direction at an angle to the vertical direction of the pot body.

[0054] In Embodiment 1, both the first tooth 35 and the second tooth 36 are racks. Both the first tooth 35 and the second tooth 36 move in a vertical direction perpendicular to the pot body. The first tooth 35 and the second tooth 36 are arranged opposite to each other, and the lower gear 51 and the driven gear 13 mesh and are located between the first tooth 35 and the second tooth 36.

[0055] like Figures 1 to 7 As shown, the cooking appliance also includes a swing structure 60 that is swingably mounted on the lid body 21, and the swing structure 60 is driven and cooperates with the upper transmission structure. The lid body 21 is also provided with an arc-shaped hole 211, and the swing structure 60 is provided with a drive elongated hole 61 corresponding to the arc-shaped hole 211. The first locking mechanism 22 is provided with a drive post 221 passing through the arc-shaped hole 211 and the drive elongated hole 61. The upper transmission structure drives the swing structure 60 to swing, so that the drive elongated hole 61 drives the drive post 221 to swing, thereby causing the first locking mechanism 22 to switch between a first unlocked position and a first locked position. Thus, when the upper transmission structure rotates on the lid, it can drive the drive elongated hole 61 on the swing structure 60 to swing, thereby driving the drive post 221 extending into the drive elongated hole 61 to swing, and the drive post 221 drives the first locking mechanism 22 to switch between the first unlocked position and the first locked position. The arc-shaped hole 211 allows the drive column 221 on the first locking mechanism 22 to pass through the arc-shaped hole 211 and extend into the drive elongated hole 61, so that when the drive elongated hole 61 moves, it can drive the drive column 221 to swing, and the arc-shaped hole 211 can avoid the swing of the drive column 221.

[0056] In Embodiment 1, the first locking mechanism 22 is a lock cover rotatably mounted on the cover body 21, and the lock cover is provided with a cover tooth 222 and a drive post 221. The cover also includes an upper cover 23 covering the lock cover and the cover body 21. The upper gear 41 and the upper coupling member 42 are fixedly connected and located on both sides of the cover body 21, so that the upper gear 41 and the upper coupling member 42 can be rotatably mounted on the cover body 21. The cover body 21 is provided with an upper coupling hole to avoid the upper coupling member 42, and the upper coupling member 42 passes into the upper coupling hole to connect with the upper gear 41.

[0057] like Figures 1 to 10As shown, the cooking appliance also includes a second locking mechanism 71. The second locking mechanism 71 is movably mounted on the pot body and has a second locking position for locking the lid to the pot body and a second unlocking position for unlocking the lid so that it can be opened from the pot body. The second locking mechanism 71 makes the connection between the lid and the pot body more reliable, improving the safety of the cooking appliance during operation. The operating structure includes a pusher 312. When the first locking mechanism 22 is in the first unlocking position and the second locking mechanism 71 is in the second locking position, the pusher 312 pushes against the second locking mechanism 71 to switch the second locking mechanism 71 from the second locking position to the second unlocking position. The pusher 312 facilitates the user's operation by driving the second locking mechanism 71 from the second locking position to the second unlocking position, making the operation simple and quick, and improving the user experience. Thus, by operating one operating structure, the user can drive both the first locking mechanism 22 and the second locking mechanism 71 to open the lid from the pot body, improving the convenience of opening the lid and enhancing the user experience. The structure is simple and stable, with low production costs. Furthermore, it avoids occupying the upper surface of the cover, making it easier to install interactive panels on the cover to further enhance the user experience.

[0058] In Embodiment 1, the second locking mechanism 71 is a fastening plate, with rotating shafts on both sides of the fastening plate, which are rotatably mounted on the middle plate 112. A return spring is provided at one end of the fastening plate to keep it in the second locked position. A snap fastener 72 is provided at the bottom of the cover body 21, capable of engaging or disengaging with the fastening plate. When the fastening plate engages with the snap fastener 72, the second locking mechanism 71 is in the second locked position. When the fastening plate disengages from the snap fastener 72, the second locking mechanism 71 is in the second unlocked position.

[0059] In Embodiment 1, the movable component 31 includes a movable body and a pressing head disposed on one side of the movable body. The pushing component 312 is a pushing rod disposed on the other side of the movable body. The insert block is disposed on the other side of the movable body and spaced apart from the pushing rod.

[0060] In Embodiment 1, the lower coupling member 52 and the lower gear 51 are located on opposite sides of the middle plate 112. A lower coupling seat is provided on the middle plate 112, and the lower coupling member 52 is rotatably disposed within the lower coupling seat. A lower coupling hole is provided on the lower coupling seat, through which the lower coupling member 52 passes and connects to the lower gear 51, so that the lower coupling member 52 and the lower gear 51 can be rotatably disposed on the middle plate 112.

[0061] In Embodiment 1, a first guide portion 14 is provided on the pot body, and a second guide portion 322 is provided on the first driving member 32. The second guide portion 322 guides and engages with the first guide portion 14 along the front-rear direction of the pot body. The first guide portion 14 and the second guide portion 322 guide the movement of the first driving member 32, enabling the first driving member 32 to move along the front-rear direction of the pot body. The first guide portion 14 is a guide post provided on the middle plate 112 of the pot body, and the second guide portion 322 is a guide hole provided on the first driving member 32. The guide hole extends along the front-rear direction of the pot body, and the guide post extends into the guide hole and engages with the guide post.

[0062] In Embodiment 1, the first driving member 32 includes a driving plate. A guide hole is provided on the driving plate, a slot is provided on one side of the driving plate, and a first tooth 35 and a second tooth 36 are provided on the other side of the driving plate. A pivot and a torsion spring are provided between the lid and the pot body to achieve automatic opening of both, that is, the fastening plate automatically separates from the buckle 72. The lid is pivotally mounted on the pot body and connected to the pot body by the torsion spring.

[0063] In Embodiment 1, the pot body includes an outer pot and an inner pot 12 disposed within the outer pot, with pot teeth 121 disposed on either the outer pot or the inner pot 12. The outer pot includes a shell 111 and a middle plate 112 disposed on the top of the shell 111. Alternatively, the outer pot includes a shell 111 and a heat insulation cover disposed within the shell 111, with pot teeth 121 disposed on the heat insulation cover. A guide post is disposed below the middle plate 112, with one end of the guide post connected to a fastener, and a first driving member 32 located between the fastener and the middle plate 112. The cooking appliance also includes a base 80 and a heating assembly disposed above the base 80. The base 80 is fixedly disposed below the shell 111. The shell 111 has mounting holes, a mounting seat 15 is disposed within the mounting holes, and a movable member 31 is movably disposed within the mounting seat 15.

[0064] The pot edge in this application can be the pot rim, a raised edge, or an outward-flared edge.

[0065] Example 1 of the cooking appliance is an electric pressure cooker. Of course, in embodiments not shown in the figure, the pot body can also be a cup or an inner pot. Other cooking appliances include rice cookers, low-pressure rice cookers, soy milk makers, food processors, stir-fry machines, slow cookers, multi-functional pots, etc.

[0066] 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.

[0067] 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.
