Description

Technical Field

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

[0002] In related technologies, the lid assembly of pressure cooking appliances is generally equipped with a locking lid or clamp structure, and the locking lid or clamp structure is equipped with lid teeth to cooperate with the pot teeth on the pot body assembly to meet the pressure requirements during the pressure cooking process.

[0003] In order to move the locking cover or caliper structure between the unlocked and locked positions, a drive component and a transmission component are usually provided on the cover assembly. The transmission component is located between the operating component and the locking cover or caliper structure to drive the locking cover or caliper structure to move.

[0004] The aforementioned driving and transmission components typically occupy a large space inside the cover assembly. Furthermore, since the transmission components need to move, space must be reserved for their movement, which affects the configuration of other structures inside the cover assembly. Utility Model Content

[0005] The main objective of this invention is to provide a transmission structure, a cover assembly, and a cooking appliance to solve the problem that the operating components and transmission components occupy a large amount of space inside the cover assembly in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a transmission structure is provided, comprising: a transmission swing member, a transmission groove provided at the first end of the transmission swing member, an internal gear ring provided at the second end of the transmission swing member, and the swing center of the transmission swing member being located between the transmission groove and the internal gear ring.

[0007] By applying the technical solution of this utility model, the transmission slot allows the transmission rod on the locking cover or caliper structure to be inserted, so that when the transmission swing member swings, it drives the locking cover or caliper structure to switch positions. The internal gear ring can mesh with the drive gear on the upper drive member, so that the upper drive member can drive the transmission swing member to swing. Because the structure that cooperates with the upper drive member is set as an internal gear ring, the upper drive member can be installed inside the transmission swing member, thereby reducing the space occupied by the transmission swing member and the upper drive member inside the cover assembly, so as to better arrange other structures. Therefore, the technical solution of this application can effectively solve the problem that the operating parts and transmission parts occupy a large space inside the cover assembly in related technologies.

[0008] Furthermore, the transmission component includes a first transmission plate and a second transmission plate. A transmission slot is disposed on the first transmission plate, and an internal gear ring is disposed on the second transmission plate. The swing center is located on the second transmission plate. The width of the first transmission plate gradually decreases in the direction away from the second transmission plate, and the outer contour of the second transmission plate away from the first transmission plate is arc-shaped. Making the outer contour of the second transmission plate arc-shaped away from the first transmission plate facilitates the arrangement of the internal gear ring. Designing the first transmission plate with a structure where its width gradually decreases in the direction away from the second transmission plate further reduces the space required by the transmission component.

[0009] Furthermore, the transmission component also includes a first side plate disposed below the first transmission plate and a second side plate disposed below the second transmission plate, the first side plate and the second side plate being butt-connected, and the internal gear ring being disposed on the second side plate; and / or, the lower surface of the first transmission plate is lower than the lower surface of the second transmission plate. The arrangement of the first side plate and the second side plate can improve the structural strength of the transmission component, while providing a basis for the placement of the internal gear ring. Making the lower surface of the first transmission plate lower than the lower surface of the second transmission plate allows the first transmission plate to be positioned as close as possible to the mounting cover.

[0010] Furthermore, the transmission structure also includes a locking hook disposed on the transmission component, the locking hook having a locking groove opening towards either the first end or the second end of the transmission component. By providing the locking hook, when the lid assembly is in the open state, the transmission structure can be locked by the locking member at a position that misaligns the lid teeth on the locking lid with the pot teeth on the pot body assembly, preventing the user from accidentally rotating the locking lid and changing the position of the lid teeth, thus affecting subsequent lid-closing operations.

[0011] According to another aspect of the present invention, a cover assembly for cooperating with a pot body assembly is provided, comprising: a mounting cover having an arc-shaped guide groove, the center of which coincides with the center of the mounting cover; a locking cover rotatably disposed below the mounting cover and having a locking position and an unlocking position, the locking cover including a cover body and a transmission rod disposed on the cover body, the transmission rod passing through the arc-shaped guide groove; an upper drive member disposed on the mounting cover and located outside the arc-shaped guide groove, the upper drive member including a drive gear; and a transmission structure disposed on the mounting cover, the transmission structure being the aforementioned transmission structure, the drive gear meshing with an internal gear ring, the transmission rod passing through a transmission groove, the drive gear driving the transmission rod to swing along the arc-shaped guide groove via a transmission swing member to switch the locking cover between the locking position and the unlocking position. During the process of the upper drive component driving the transmission structure to swing and thus driving the transmission rod to move along the arc-shaped guide groove, the main body of the transmission structure and the upper drive component are located on the outside of the arc-shaped guide groove. Only a small part of the first end of the transmission structure moves to the inside of the arc-shaped guide groove, so that the transmission swing component and the upper drive component occupy less space inside the cover assembly.

[0012] Furthermore, a fixed shaft is provided on the mounting cover, and a rotating hole is provided on the transmission swing component, through which the fixed shaft passes. By providing a fixed shaft on the mounting cover to realize the swing of the transmission swing component around the fixed shaft, it has the advantage of simple structure.

[0013] Furthermore, the lid assembly also includes a locking element, which is movably mounted on the mounting cover in the vertical direction and has a locked position and a disengaged position. The locking element includes a trigger part and a locking part. When the lid assembly is not placed on the pot body assembly, the locking element is in the locked position, the trigger part extends downward from the mounting cover, and the locking part locks the transmission swing member to restrict its swing. When the lid assembly is placed on the pot body assembly, the locking element is in the disengaged position, the trigger part is pressed and drives the locking element to move upward, separating the locking part from the transmission swing member, allowing the transmission swing member to swing. By providing a trigger part that can extend downward from the mounting cover, when the lid assembly is placed on the pot body assembly, the pot body assembly can push the trigger part, causing the locking element to move from the locked position to the unlocked position. This achieves automatic unlocking of the locking element after the lid assembly is closed, without requiring additional user operation, thus simplifying user operation.

[0014] Furthermore, the locking part includes a locking block extending from top to bottom; and / or, the cover assembly also includes a retaining member disposed above the locking member and applying a downward resisting force to the locking member, so that the locking member is held in the locked position. Locking the transmission component by the cooperation of the locking block and the locking groove has the advantage of simple structure. When the cover assembly is opened, the locking member can move downward under the action of the retaining member and remain in the locked position, enabling the locking member to automatically lock the transmission component after the cover is opened, without requiring additional operation from the user, thus facilitating user operation.

[0015] Furthermore, the cover assembly also includes a faceplate and a retainer. A guide rod is provided on the mounting cover, and the locking element includes a guide cylinder with the guide rod passing through it. The retainer is a compression spring housed within the guide cylinder and sleeved around the guide rod. The faceplate is positioned above the mounting cover, and the two ends of the compression spring abut against the bottom wall of the faceplate and the guide cylinder, respectively. The guide cylinder and guide rod simultaneously guide the locking element and install the compression spring, achieving functional integration and offering the advantage of a simple structure. The upper end of the compression spring directly abuts against the faceplate, eliminating the need for additional abutment structures.

[0016] According to another aspect of this utility model, a cooking appliance is provided, including a pot body assembly and a lid assembly that is openable and closable on the pot body assembly. The lid assembly is the aforementioned lid assembly. The pot body assembly includes: a shell; a pot body disposed within the shell; an operating member disposed on the shell and protruding outwards from the shell; and a lower drive member disposed on the shell and extending upwards from the shell. The lower end of the lower drive member engages with the operating member, and the upper end of the lower drive member engages with the upper drive member. By providing the operating member and the lower drive member on the pot body assembly, the power of the operating member can be transmitted sequentially through the lower drive member, the upper drive member, and the transmission structure to the locking lid. This allows the operating member for user operation to be located on the pot body assembly, freeing up space above the lid assembly for a larger control panel or other structures, thus facilitating user operation.

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.

[0047] like Figure 1 , Figure 3 and Figure 6 As shown, this application provides a transmission structure. An embodiment of the transmission structure of this application includes a transmission swing member 10. The first end of the transmission swing member 10 is provided with a transmission long groove 11, and the second end of the transmission swing member 10 is provided with an internal gear ring 12. The swing center of the transmission swing member 10 is located between the transmission long groove 11 and the internal gear ring 12.

[0048] Applying the technical solution of this embodiment, the transmission slot 11 allows the transmission rod on the locking cover 50 or the caliper structure to be inserted, so that when the transmission swing member 10 swings, it drives the locking cover 50 or the caliper structure to switch positions. The internal gear ring 12 can mesh with the drive gear 61 on the upper drive member 60, so that the upper drive member 60 can drive the transmission swing member 10 to swing. Since the structure that cooperates with the upper drive member 60 is set as the internal gear ring 12, the upper drive member 60 can be installed inside the transmission swing member 10, thereby reducing the space occupied by the transmission swing member 10 and the upper drive member 60 inside the cover assembly, so as to better arrange other structures. Therefore, the technical solution of this embodiment can effectively solve the problem that the operating members and transmission members occupy a large space inside the cover assembly in the related art.

[0049] like Figure 1 As shown, the transmission swing member 10 includes a first transmission plate 13 and a second transmission plate 14. A transmission groove 11 is disposed on the first transmission plate 13, and an internal gear ring 12 is disposed on the second transmission plate 14. The swing center is located on the second transmission plate 14. In the direction away from the second transmission plate 14, the width of the first transmission plate 13 gradually decreases, and the outer contour of the second transmission plate 14 away from the first transmission plate 13 is arc-shaped. Setting the outer contour of the second transmission plate 14 away from the first transmission plate 13 to be arc-shaped facilitates the arrangement of the internal gear ring 12. Setting the first transmission plate 13 to have a structure in which the width gradually decreases in the direction away from the second transmission plate 14 can further reduce the space required by the transmission swing member 10.

[0050] Specifically, in this embodiment, the internal gear ring 12 is part of the entire internal gear, as long as it can meet the requirement of driving the swing range of the transmission swing member 10.

[0051] like Figure 1 As shown, the transmission component 10 also includes a first side plate 21 disposed below the first transmission plate 13 and a second side plate 22 disposed below the second transmission plate 14. The first side plate 21 and the second side plate 22 are connected together, and the internal gear ring 12 is disposed on the second side plate 22. The arrangement of the first side plate 21 and the second side plate 22 can improve the structural strength of the transmission component 10, and at the same time provide a basis for the arrangement of the internal gear ring 12.

[0052] like Figure 1 As shown, in this embodiment, reinforcing plates are provided on the outer periphery of both the transmission groove 11 and the rotating hole 15 to increase the strength of the transmission structure.

[0053] like Figure 1 , Figure 11 ,and Figure 12As shown, the lower surface of the first transmission plate 13 is lower than the lower surface of the second transmission plate 14. In this embodiment, the transmission structure drives the locking cover 50 to rotate. The transmission rod 52 on the locking cover 50 needs to pass through the mounting cover 40 from bottom to top and extend into the transmission groove 11, so that the lower surface of the first transmission plate 13 is lower than the lower surface of the second transmission plate 14, so that the first transmission plate 13 can be set as close as possible to the mounting cover 40.

[0054] like Figure 1 and Figure 3 As shown, the transmission structure also includes a locking hook 30 disposed on the transmission member 10. The locking hook 30 has a locking groove 31 with an opening facing either the first end of the transmission member 10 or the second end of the transmission member 10. By providing the locking hook 30, when the lid assembly is in the open state, the transmission structure can be locked by the locking member 70 at a position where the lid teeth on the locking lid 50 are misaligned with the pot teeth on the pot body assembly, preventing the user from accidentally rotating the locking lid 50 to change the position of the lid teeth and affecting subsequent lid closing operations.

[0055] like Figure 2 As shown, this application also provides a cover assembly for cooperating with a pot body assembly. An embodiment of the cover assembly of this application includes: a mounting cover 40, a locking cover 50, an upper drive member 60, and a transmission structure. The mounting cover 40 is provided with an arc-shaped guide groove 41, the center of which coincides with the center of the mounting cover 40. The locking cover 50 is rotatably disposed below the mounting cover 40 and has a locking position and an unlocking position. The locking cover 50 includes a cover body 51 and a transmission rod 52 disposed on the cover body 51. The transmission rod 52 passes through the arc-shaped guide groove 41. The upper drive member 60 is disposed on the mounting cover 40 and located outside the arc-shaped guide groove 41. The upper drive member 60 includes a drive gear 61. The transmission structure is disposed on the mounting cover 40. The transmission structure is the transmission structure described above. The drive gear 61 meshes with the internal gear ring 12. The transmission rod 52 passes through the transmission long groove 11. The drive gear 61 drives the transmission rod 52 to swing along the arc-shaped guide groove 41 through the transmission swing member 10 to switch the locking cover 50 between the locking position and the unlocking position. The arc-shaped guide groove 41 can guide the transmission rod 52 and limit its extreme position. The transmission rod 52 passes through the arc-shaped guide groove 41 and the transmission long groove 11 from bottom to top. The upper driving member 60 is located on the outside of the arc-shaped guide groove 41. Correspondingly, the part of the transmission structure that cooperates with the upper driving member 60 is also located on the outside of the arc-shaped guide groove 41. During the process of the upper driving member 60 driving the transmission structure to swing and thus driving the transmission rod 52 to move along the arc-shaped guide groove 41, the main part of the transmission structure and the upper driving member 60 are located on the outside of the arc-shaped guide groove 41. Only a small part of the first end of the transmission structure will move to the inside of the arc-shaped guide groove 41, so that the space occupied by the transmission swing member 10 and the upper driving member 60 inside the cover assembly is small.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, a fixed shaft 42 is provided on the mounting cover 40, and a rotating hole 15 is provided on the transmission swing member 10, with the fixed shaft 42 passing through the rotating hole 15. By providing a fixed shaft 42 on the mounting cover 40 to realize the swing of the transmission swing member 10 around the fixed shaft 42, it has the advantage of simple structure.

[0057] like Figure 2 and Figure 4 As shown, the mounting cover 40 is also provided with a mounting cylinder 44, and the upper drive component 60 is installed inside the mounting cylinder 44.

[0058] like Figure 3 and Figure 5 As shown, the lid assembly also includes a locking member 70. The locking member 70 is movably disposed on the mounting cover 40 in the vertical direction and has a locked position and a disengaged position. The locking member 70 includes a trigger part 71 and a locking part 72. When the lid assembly is not placed on the pot assembly, the locking member 70 is in the locked position, the trigger part 71 extends downward from the mounting cover 40, and the locking part 72 locks the transmission swing member 10 to restrict the swing of the transmission swing member 10. When the lid assembly is placed on the pot assembly, the locking member 70 is in the disengaged position. The trigger part 71 is pressed, causing the locking member 70 to move upward as a whole, and the locking part 72 separates from the transmission swing member 10, allowing the transmission swing member 10 to swing. The locking member 70 can cooperate with the locking hook 30 on the transmission structure, so that when the lid assembly is in the open state, the locking member 70 can lock the transmission structure at a position where the cap teeth on the locking cover 50 are misaligned with the pot teeth on the pot assembly, preventing the user from accidentally rotating the locking cover 50 to change the position of the cap teeth and affecting subsequent lid closing operations. By providing a trigger part 71 that can extend downward from the mounting cover 40, when the cover assembly is closed on the pot body assembly, the pot body assembly can push the trigger part 71 to move the locking member 70 from the position of the locking transmission swing member 10 to the position of the unlocking transmission swing member 10, so that the locking member 70 can be automatically unlocked after the cover assembly is closed, without requiring any additional operation from the user, making it convenient for the user.

[0059] like Figure 3 and Figure 5 As shown, the locking part 72 includes a locking block 721 extending from top to bottom. By providing the locking block 721 extending from top to bottom, when the locking member 70 moves down, the locking block 721 can extend into the locking groove 31 to lock the transmission swing member 10; when the locking member 70 moves, the locking block 721 can disengage from the locking groove 31, so that the transmission swing member 10 can swing, which has the advantage of simple structure.

[0060] like Figure 7As shown, the trigger part 71 is a trigger rod, and correspondingly, the mounting cover 40 is provided with a through hole for the trigger rod to pass downward. The locking part 72 is located between the guide cylinder 73 and the trigger part 71. The locking part 72 also includes a cantilever rod 722, and a locking block 721 is provided at the free end of the cantilever rod 722 and extends downward. The locking block 721 is provided with a guide ramp to facilitate the alignment between the locking block 721 and the locking groove 31.

[0061] In this embodiment, the cover assembly further includes a retainer, which is disposed above the locking member 70 and applies a downward pushing force to the locking member 70 to keep the locking member 70 in the locked position. Specifically, when the cover assembly is opened, the locking member 70 can move downward under the action of the retainer and remain in the locked position, enabling the locking member 70 to automatically lock the transmission swing member 10 after the cover is opened, without requiring additional operation by the user, thus facilitating user use.

[0062] like Figures 3 to 5 As shown, the cover assembly also includes a faceplate 90 and a retainer. A guide rod 43 is provided on the mounting cover 40. The locking member 70 includes a guide cylinder 73, with the guide rod 43 passing through it. The retainer is a compression spring disposed within the guide cylinder 73 and sleeved around the guide rod 43. The faceplate 90 is positioned above the mounting cover 40. The two ends of the compression spring abut against the faceplate 90 and the bottom wall of the guide cylinder 73, respectively. Specifically, the guide cylinder 73 is a cylindrical structure with an open top and a bottom wall. A through hole is provided on the bottom wall of the guide cylinder 73 for the guide rod 43 to pass through. The guide cylinder 73 and the guide rod 43 simultaneously guide the locking member 70 and install the compression spring, achieving functional integration and offering the advantage of a simple structure. The upper end of the compression spring directly abuts against the faceplate 90, eliminating the need for additional abutment structures.

[0063] like Figures 7 to 12As shown, this application also provides a cooking appliance. An embodiment of the cooking appliance of this application includes a pot body assembly and a lid assembly that is openable and closable on the pot body assembly. The lid assembly is the aforementioned lid assembly. The pot body assembly includes: a housing 100, a pot body 110, an operating member 120, and a lower driving member 130. The pot body 110 is disposed within the housing 100; the operating member 120 is disposed on the housing 100 and extends outward from the housing 100; the lower driving member 130 is disposed on the housing 100 and extends upward from the housing 100. The lower end of the lower driving member 130 is driven to engage with the operating member 120, and the upper end of the lower driving member 130 is driven to engage with the upper driving member 60. By setting the operating component 120 and the lower drive component 130 on the pot body assembly, the power of the operating component 120 can be transmitted sequentially through the lower drive component 130, the upper drive component 60 and the transmission structure to the locking cover 50. This allows the operating component 120, which is used for user operation, to be set on the pot body assembly, thereby freeing up the space above the cover assembly. This allows for the installation of a larger operating panel or other structures above the cover assembly, making it more convenient for users.

[0064] like Figure 6 As shown, the upper drive member 60 also includes an upper coupling part 62 disposed at the lower end of the drive gear 61. The upper coupling part 62 protrudes downward from the mounting cover 40 to realize the coupling between the upper drive member 60 and the lower drive member 130.

[0065] like Figures 7 to 10 As shown, the operating component 120 includes an operating knob 121 and a translation transmission plate 122. A push rod 1211 is provided on the operating knob 121, offset from the center of the operating knob 121. When the user rotates the operating knob 121, the push rod 1211 swings in an arc or rotates in a circle. The translation transmission plate 122 is provided with a vertically extending mating groove 1221. When the push rod 1211 swings, it pushes against the side wall of the mating groove 1221, causing the translation transmission plate 122 to move laterally.

[0066] like Figures 7 to 9 As shown, the housing 100 includes an outer shell 101, a middle plate 102 disposed above the outer shell 101, and a bottom shell 103 disposed below the outer shell 101. The outer shell 101 is provided with a mounting opening 1011. The housing 100 also includes a mounting base 104 disposed at the mounting opening 1011. An operating knob 121 passes through the mounting base 104 and is mounted on the outer shell 101 through the mounting base 104. The mounting base 104 is provided with an arc-shaped groove 1041, and a push rod 1211 passes through the arc-shaped groove 1041.

[0067] like Figure 8 and Figure 10As shown, the lower drive member 130 includes a lower coupling part 132 and a lower gear 131 disposed below the lower coupling part 132. A drive spur gear 1222 is disposed on the translation transmission plate 122. When the translation transmission plate 122 moves, the drive spur gear 1222 and the lower gear 131 mesh with each other to drive the lower drive member 130 to rotate.

[0068] like Figure 6 and Figure 10 As shown, a coupling groove is provided on the lower coupling part 132, and a coupling post is provided on the upper coupling part 62 that can cooperate with the coupling groove to prevent rotation. When the cover assembly is placed on the pot body assembly, the coupling post is inserted into the coupling groove. When the lower drive member 130 rotates, it can drive the upper drive member 60 to rotate synchronously, thereby realizing the transmission of power from the pot body assembly to the cover assembly.

[0069] like Figure 7 and Figure 8 As shown, the cooker body assembly also includes a lower hook 141 and an elastic element disposed within the housing 100. The lower hook 141 is swayably disposed within the housing 100 and can engage or disengage with an upper hook 142 fixedly disposed on the lid assembly. The elastic element is disposed between the lower hook 141 and the housing 100 and abuts against the lower hook 141, so that the lower hook 141 is held in the position engaged with the upper hook 142. That is, without any other external force, the lower hook 141 is always engaged with the upper hook 142. The mating groove 1221 on the translation transmission plate 122 is a through groove that penetrates the translation transmission plate 122 along the inner and outer directions of the housing 100. The push rod 1211 can push the lower hook 141 to overcome the force of the elastic element, so that the lower hook 141 swings to the position where it is separated from the upper hook 142, thereby disengaging the lower hook 141 from the upper hook 142. When the user stops operating the operating component 120, the lower hook 141 will be reset to the position where it engages with the upper hook 142 under the action of the elastic element.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
