Description

Technical Field

[0001] This invention relates to the field of small household appliance technology, and more specifically, to a drive structure, a cover assembly, and a cooking appliance. Background Technology

[0002] In related technologies, pressure cooking appliances generally include a pot body assembly and a lid assembly. Because the internal pressure of pressure cooking appliances is high during cooking, pot teeth and lid teeth that can interlock are set on the pot body assembly and the lid assembly respectively to meet the pressure requirements during the cooking process. In addition, a hook and latch structure is set between the pot body assembly and the lid assembly to achieve double locking.

[0003] When the lid is closed, the hook mechanism locks in place first, and then the pot teeth and lid teeth lock in place. When the lid is opened, the locking mechanism between the pot teeth and lid teeth is released first, and then the locking mechanism of the hook mechanism is released.

[0004] Because of the aforementioned dual locking structure, users need to perform two operations when opening the lid. The first operation disengages the teeth between the pot teeth and the lid teeth, and the second operation disengages the hook structure, making the lid opening operation cumbersome and affecting the user experience. Summary of the Invention

[0005] The main objective of this invention is to provide a driving structure, a lid assembly, and a cooking appliance to solve the problem of cumbersome lid opening operations in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a driving structure is provided, comprising: a driving lever having a main rod segment and a driving rod segment disposed at one end of the main rod segment, the swing center of the driving lever being located on the main rod segment, and the driving rod segment having a lateral notch; a swing arm swayably disposed on the main rod segment and having a first state of abutting with the driving rod segment and sealing the lateral notch, and a second state of being separated from the driving rod segment; and a retaining member disposed between the driving lever and the swing arm and applying a retaining force to the swing arm so that the swing arm is held in the first state; wherein the driving lever has a closed position, a disengaged position, and a disengaged position, the disengaged position being located between the closed position and the disengaged position, the swing arm being held in the first state when the driving lever swings between the closed position and the disengaged position, and the swing arm being in the second state when the driving lever swings between the disengaged position and the disengaged position.

[0007] Applying the technical solution of this invention, a driving structure is disposed on the cover assembly and can drive the pressure cover of the cover assembly to rotate. The driving structure includes a driving lever and a swing arm. The driving segment of the driving lever has a lateral notch. The swing arm is oscillatingly disposed on the driving lever and has a first state of blocking the lateral notch and a second state of being separated from the driving segment, thereby enabling the driving lever to have sequentially arranged closing position, disengaged position, and disengaged position. Specifically, when the swing arm is in the first state, the swing arm remains stationary relative to the drive lever and blocks the lateral notch. A drive groove is formed between the swing arm and the drive lever segment for the corresponding structure on the pressure cover to pass through. When the drive lever rotates, the groove wall of the drive groove drives the corresponding structure on the pressure cover to rotate, thereby driving the pressure cover to rotate. During this process, the pot teeth on the pot body assembly and the cover teeth on the lid assembly can be aligned or misaligned. When the pot teeth and the cover teeth are aligned, the drive lever is in the closed position. When the pot teeth and the cover teeth are misaligned, the drive lever is in the disengaged position. When the swing arm is in the second state, the swing arm is separated from the drive lever segment. The swing arm remains in a state of engagement with the corresponding structure on the pressure cover, and the pressure cover remains stationary. The drive lever can continue to swing in a direction away from the corresponding structure on the pressure cover to realize the disengagement operation of the hook structure between the pot body assembly and the lid assembly. At this time, the drive lever is in the disengaged position. Because the drive lever swings in the same direction throughout its movement from the closed position to the disengaged position and then to the tripped position, the user only needs to perform one operation to move the drive lever to the disengaged and tripped positions respectively to open the lid. This simplifies the user's operation and improves the user experience. Therefore, the technical solution of this application can effectively solve the problem of cumbersome lid opening operations in related technologies.

[0008] Furthermore, the swing arm includes a rotating part, a driving engagement rod, and a retaining rod. The driving engagement rod and the retaining rod are respectively disposed on both sides of the rotating part. The driving engagement rod is correspondingly disposed with the driving rod segment and can block the lateral notch. The retaining member is disposed between the retaining rod and the main rod segment. The swing arm forms a lever structure, enabling the swing arm to switch between a first state and a second state, which has the advantage of simple structure.

[0009] Furthermore, the retaining member includes a compression spring, with its two ends abutting against the main body segment and the retaining rod, respectively; and / or, the main body segment has a receiving recess and a limiting cover, the limiting cover being positioned over the receiving recess, with both the retaining rod and the retaining member located within the receiving recess, and one end of the retaining member extending into the limiting cover. The compression spring holds the swing arm in its first state, offering the advantage of simplicity. The limiting cover can limit at least a portion of the retaining member, ensuring its stability during use.

[0010] According to another aspect of the present invention, a cover assembly is provided, comprising: a mounting cover; a pressure-bearing cover rotatably disposed below the mounting cover; and a drive structure disposed on the mounting cover and drivingly cooperating with the pressure-bearing cover to drive the pressure-bearing cover to rotate, wherein the drive structure is the drive structure described above. The drive structure described above can effectively solve the problem of cumbersome cover opening operations in related technologies, and the cover assembly having the drive structure described above also has the aforementioned advantages.

[0011] Furthermore, the drive structure is positioned above the mounting cover, which has an arc-shaped perforation. The pressure cover includes a cover body and a connecting post mounted on the cover body. The connecting post extends upward through the arc-shaped perforation and into the space between the drive rod segment and the swing arm. The arc-shaped perforation has a closing end and a disengaging end. When the drive swing rod swings between the closing and disengaging positions, it corresponds to the arc-shaped perforation. When the drive swing rod swings between the disengaging and tripping positions, it is positioned outside the arc-shaped perforation and close to the disengaging end. The disengaging end stops the connecting post, and the connecting post abuts against the swing arm and overcomes the holding force, thus placing the swing arm in the second state. The arc-shaped perforation guides the connecting post and limits its rotation range. By stopping the connecting post at the disengaging end, the drive swing rod can continue to swing outward to achieve the tripping operation, while the pressure cover remains stationary.

[0012] Furthermore, the mounting cover is provided with a guide groove and a fixing post. The main rod segment has a fulcrum hole and a driven hole. The fixing post passes through the fulcrum hole. The cover assembly also includes a driving component movably mounted on the mounting cover. The driving component includes a slider slidably mounted in the guide groove and a driving arm passing through the driven hole. When the slider slides, the driving arm drives the driving swing rod to swing around the fixing post. The guide groove on the mounting cover can guide the slider of the driving component, and the fixing post on the mounting cover forms the swing fulcrum of the driving swing rod, thereby ensuring that the slider, the driving swing rod, and the pressure cover can all move according to a predetermined trajectory.

[0013] Furthermore, the drive component also includes a first coupling portion disposed on the slider and protruding downward from the mounting cover. The first coupling portion protruding downward from the mounting cover allows it to couple with a coupling structure on the cookware body assembly. This allows the operating component to be disposed on the cookware body assembly, freeing up space above the cover assembly for structures such as an operation panel, thereby improving the user experience.

[0014] According to another aspect of the present invention, a cooking utensil is provided, including a lid assembly, wherein the lid assembly is the lid assembly described above. The lid assembly described above effectively solves the problem of cumbersome lid opening operations in related technologies, and the cooking utensil having the lid assembly described above also has the aforementioned advantages.

[0015] According to another aspect of the present invention, a cooking appliance is provided, comprising a pot body assembly and a lid assembly that is openable and closable over the pot body assembly. The lid assembly is the aforementioned lid assembly. The pot body assembly includes: a housing; and a sliding member slidably disposed on the housing and having a second coupling portion protruding upward from the housing. The second coupling portion engages with a first coupling portion and drives a slider to slide. The second coupling portion of the sliding member engages with the first coupling portion to drive the slider to slide, thereby driving the pressure-bearing lid to rotate. When it is necessary to open or close the lid, the user only needs to control the sliding member to slide.

[0016] Furthermore, the housing includes an outer shell and a middle plate disposed above the outer shell. The sliding member includes a first sliding portion located below the middle plate and a second sliding portion located above the middle plate and fixedly connected to the first sliding portion. A second coupling portion is disposed on the second sliding portion. By configuring the sliding member as a split structure and placing the second sliding portion with the second coupling portion above the middle plate, that is, placing the second coupling portion above the housing, coupling between the first coupling portion and the second coupling portion can be easily achieved.

[0017] Furthermore, the first coupling part includes a coupling post disposed on the slider and extending downward from the mounting cover; the second coupling part includes a coupling groove disposed on the second sliding part; when the cover assembly is closed on the pot body assembly, the coupling post is inserted into the coupling groove; and / or, the middle plate is provided with a mounting protrusion, the mounting protrusion having a mounting opening; the second sliding part is slidably disposed above the mounting protrusion and blocks the mounting opening; the sliding member also includes a connecting arm passing through the mounting opening and connecting between the first sliding part and the second sliding part. The sliding member drives the driving member to move through the cooperation between the coupling post and the coupling groove, which has the advantage of simple structure. The first sliding part and the second sliding part are fixedly connected by the connecting arm, which also has the advantage of simple structure.

[0018] Furthermore, the cooker body assembly also includes a screw-operated component exposed outside the outer shell. The screw-operated component is equipped with driving teeth, and the first sliding part is equipped with driven teeth that mesh with the driving teeth, so that the first sliding part moves when the screw-operated component rotates. Setting the component as a screw-operated component adapts to user habits and facilitates use. The rotation of the screw-operated component is converted into the sliding of the sliding component through the cooperation between the driving teeth and driven teeth, offering advantages such as simple structure and reliable transmission.

[0019] Furthermore, the outer casing is provided with mounting holes, and the casing also includes a mounting base disposed at the mounting holes. The screwing operation component includes a knob and a drive wheel. The knob is rotatably mounted on the mounting base and extends outward from the outer casing. The drive wheel is located inside the outer casing and is fixedly connected to the knob. Drive teeth are disposed on the drive wheel. By making the screwing operation component a split structure and providing a mounting base on the outer casing, it is convenient to install the screwing operation component onto the outer casing.

[0020] Furthermore, the mounting cover is provided with a first hook, and the middle plate is movably provided with a second hook. When the cover assembly is placed on the pot body assembly, the second hook has a latching position that engages with the first hook and a release position that is separated from the first hook. The sliding member has a first push top. When the sliding member drives the drive lever to swing between the closed position and the disengaged position via the slider, the first push top separates from the second hook. When the sliding member drives the drive lever to swing from the disengaged position to the release position via the slider, the first push top pushes the second hook and switches the second hook from the latching position to the release position. Alternatively, the screwing operation member has a second push top. When the screwing operation member drives the drive lever to swing between the closed position and the disengaged position via the sliding member and the slider, the second push top separates from the second hook. When the screwing operation member drives the drive lever to swing from the disengaged position to the release position via the sliding member and the slider, the second push top pushes the second hook and switches the second hook from the latching position to the release position. By setting a first push top or a second push top, when the drive lever swings from the disengaged position to the disengaged position, the first push top or the second push top pushes the second hook, realizing the disengagement between the second hook and the first hook. This enables the disengagement of the teeth first and then the disengagement during the opening process, avoiding the situation where the lid assembly flips up and the lid teeth collide rigidly when there is still an overlap between the pot teeth and the lid teeth.

[0021] Furthermore, the pot body assembly also includes a locking element disposed on the housing. The locking element has a locked position and an unlocked position. The locking element includes a locking lever and a trigger lever. When the lid assembly is not closed on the pot body assembly, the locking element is in the locked position, the trigger lever extends upward through the housing, and the locking lever locks the sliding member. When the lid assembly is closed on the pot body assembly, the lid assembly presses down the trigger lever and drives the locking element to switch from the locked position to the unlocked position, and the locking lever unlocks the sliding member. When the lid assembly is not closed on the pot body assembly, the locking lever locks the sliding member in a position that places the drive lever in the disengaged position. This ensures that the lid teeth are misaligned with the pot teeth during the process of the lid assembly closing on the pot body assembly, preventing collision between the pot teeth and the lid teeth.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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 invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] 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.

[0056] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the 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 figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0057] like Figures 1 to 3 as well as Figures 7 to 11As shown, this application provides a driving structure, and an embodiment of the driving structure of this application includes: a driving rocker arm 10, a rocker arm 20, and a retainer 30. The drive lever 10 has a main rod segment 11 and a drive rod segment 12 disposed at one end of the main rod segment 11. The swing center of the drive lever 10 is located on the main rod segment 11. The drive rod segment 12 has a lateral notch 121. The swing arm 20 is swingably disposed on the main rod segment 11 and has a first state in which it is mated with the drive rod segment 12 and blocks the lateral notch 121, and a second state in which it is separated from the drive rod segment 12. The retainer 30 is disposed between the drive lever 10 and the swing arm 20 and applies a retaining force to the swing arm 20 so that the swing arm 20 is held in the first state. The drive lever 10 has a closed position, a disengaged position and a disengaged position. The disengaged position is located between the closed position and the disengaged position. When the drive lever 10 swings between the closed position and the disengaged position, the swing arm 20 is held in the first state. When the drive lever 10 swings between the disengaged position and the disengaged position, the swing arm 20 is in the second state.

[0058] Applying the technical solution of this embodiment, the driving structure is disposed on the cover assembly and can drive the pressure cover 50 of the cover assembly to rotate. The driving structure includes a driving lever 10 and a swing arm 20. The driving rod segment 12 of the driving lever 10 has a lateral notch 121. The swing arm 20 is swayably disposed on the driving lever 10 and has a first state of blocking the lateral notch 121 and a second state of being separated from the driving rod segment 12, thereby enabling the driving lever 10 to have sequentially arranged closed cover position, disengaged tooth position, and disengaged latch position. Specifically, when the swing arm 20 is in the first state, the swing arm 20 remains stationary relative to the drive lever 10 and blocks the lateral notch 121. A drive groove is formed between the swing arm 20 and the drive lever segment 12 for the corresponding structure on the pressure cover 50 (specifically, the connecting post 52 mentioned below) to pass through. When the drive lever 10 rotates, the groove wall of the drive groove drives the corresponding structure on the pressure cover 50 to rotate, thereby driving the pressure cover 50 to rotate. In this process, the pot teeth on the pot body assembly and the cover teeth on the lid body assembly can be aligned or misaligned. When the pot... When the lid and cookware teeth are aligned, the drive lever 10 is in the closed position. When the lid and cookware teeth are misaligned, the drive lever is in the disengaged position. When the swing arm 20 is in the second state, the swing arm 20 is separated from the drive rod segment 12. The swing arm 20 remains in a state of engagement with the corresponding structure on the pressure cover 50, and the pressure cover 50 remains stationary. The drive lever 10 can continue to swing away from the corresponding structure on the pressure cover 50 to achieve the disengagement operation of the hook structure between the cookware body assembly and the lid assembly. At this time, the drive lever 10 is in the disengaged position. Since the drive lever 10 always swings in the same direction during the process of moving from the closed position to the disengaged position and then to the disengaged position, the user only needs to perform one operation to drive the drive lever 10 to the disengaged position and the disengaged position to open the lid, which simplifies the user's operation and improves the user experience. Therefore, the technical solution of this embodiment can effectively solve the problem of cumbersome lid opening operation in related technologies.

[0059] Specifically, in this embodiment, when the drive lever 10 is in the closed position ( Figure 11 When the pot teeth on the pot body assembly and the lid teeth on the lid assembly are aligned, the hook structure between the pot body assembly and the lid assembly remains in the hook state; when the drive lever 10 is in the disengaged position (in the middle position), the pot teeth on the pot body assembly and the lid teeth on the lid assembly are aligned and ..., the pot teeth on the pot body assembly and the lid teeth on the lid assembly are aligned and the hook structure between the pot body assembly and the lid assembly are in the hook state. Figure 8 When the pot body assembly and the lid assembly are in the middle position, the pot teeth on the pot body assembly and the lid teeth on the lid assembly are misaligned, and the hook structure between the pot body assembly and the lid assembly remains in the hook state; when the drive lever 10 is in the disengaged position ( Figure 10 When the lid is closed, the pot teeth on the pot body assembly and the lid teeth on the lid assembly are misaligned, and the hook and latch structure between the pot body assembly and the lid assembly is in a disengaged state. The aforementioned lid-closed position, tooth-disengaged position, and disengaged position all refer to a specific position.

[0060] It should be noted that the "second state" mentioned above refers to a state within a process, not a state at a specific location. When the driving structure... Figure 8 Switching to the current state Figure 10 During the process, the swing arm 20 is always in the second state.

[0061] like Figure 1 As shown, the swing arm 20 includes a rotating part 21, a driving engagement rod 22, and a retaining rod 23. The driving engagement rod 22 and the retaining rod 23 are respectively disposed on both sides of the rotating part 21. The driving engagement rod 22 is correspondingly disposed with the driving rod segment 12 and can block the lateral notch 121. The retaining member 30 is disposed between the retaining rod 23 and the main rod segment 11. The swing arm 20 forms a lever structure, so that the swing arm 20 can switch between a first state and a second state, which has the advantage of simple structure.

[0062] like Figure 1 The rotating part 21 shown has a rotating hole, and a rotating shaft is provided on the main rod section 11. The rotating shaft passes through the rotating hole so that the swing arm 20 can swing relative to the driving swing rod 10 with the axis of the rotating shaft as the swing axis.

[0063] like Figure 1 and Figure 2 As shown, the retaining member 30 includes a compression spring, with its two ends abutting against the main body segment 11 and the retaining rod 23, respectively. The compression spring keeps the swing arm 20 in the first state, which has the advantage of simplicity.

[0064] like Figure 1 and Figure 2 As shown, the main body segment 11 has a receiving recess 111 and a limiting cover 112. The limiting cover 112 covers the receiving recess 111. The retaining rod 23 and the retaining member 30 are both located within the receiving recess 111, and one end of the retaining member 30 extends into the limiting cover 112. The receiving recess 111 forms an installation space for installing the retaining rod 23 and the retaining member 30. The limiting cover 112 is disposed within the receiving recess 111, and one end of the retaining member 30 extends into the limiting cover 112, so that the limiting cover 112 can limit at least a portion of the retaining member 30, ensuring the stability of the retaining member 30 during use.

[0065] like Figures 2 to 4As shown, this application also provides a cover assembly. An embodiment of the cover assembly includes: a mounting cover 40, a pressure-bearing cover 50, and a driving structure. The pressure-bearing cover 50 is rotatably disposed below the mounting cover 40; the driving structure is disposed on the mounting cover 40 and drives the pressure-bearing cover 50 to rotate. The driving structure is the one described above. The driving structure effectively solves the problem of cumbersome cover opening operations in related technologies, and the cover assembly with the driving structure also has the aforementioned advantages.

[0066] like Figure 2 As shown, the pressure cover 50 is provided with cover teeth. The cover assembly also includes a face cover 120 disposed above the mounting cover 40.

[0067] like Figures 7 to 11 As shown, the drive structure is located above the mounting cover 40. The mounting cover 40 has an arc-shaped perforation 41. The pressure cover 50 includes a cover body 51 and a connecting post 52 provided on the cover body 51. The connecting post 52 extends upward through the arc-shaped perforation 41 and into the space between the drive rod segment 12 and the swing arm 20. The arc-shaped perforation 41 has a closing end 411 and a disengaging end 412. When the drive swing rod 10 swings between the closing position and the disengaging position, the drive swing rod 10 corresponds to the arc-shaped perforation 41. When the drive swing rod 10 swings between the disengaging position and the disengaging position, the drive swing rod 10 is located outside the arc-shaped perforation 41 and close to the disengaging end 412. The disengaging end 412 stops the connecting post 52, and the connecting post 52 abuts against the swing arm 20 and overcomes the holding force, so that the swing arm 20 is in the second state.

[0068] The arc-shaped perforation 41 guides the connecting post 52 and restricts its rotation range (i.e., restricts the rotation range of the pressure cover 50). When the connecting post 52 abuts against the cover end 411, the driving swing rod 10 is in the cover position, and the pot teeth and cover teeth are aligned. When the connecting post 52 abuts against the toothed end 412 and the driving swing rod 10 does not move outside the range of the arc-shaped perforation 41, the driving swing rod 10 is in the toothed position, the pot teeth and cover teeth are misaligned, and the hook structure remains in the hooked state (maximum engagement state). When the connecting post 52 abuts against the toothed end 412 and the driving swing rod 10 continues to swing outside the range of the arc-shaped perforation 41, the hook structure begins to disengage until the hook structure is completely disengaged. At this time, the driving swing rod 10 is in the disengaged position, and the opening between the driving rod segment 12 and the swing arm 20 is at its maximum.

[0069] like Figures 2 to 4As shown, the mounting cover 40 is provided with a guide groove 42 and a fixing post 43. The main body rod segment 11 has a fulcrum hole 113 and a driven hole 114. The fixing post 43 passes through the fulcrum hole 113. The cover assembly also includes a drive member 60 that is movably disposed on the mounting cover 40. The drive member 60 includes a slider 61 that is slidably disposed in the guide groove 42 and a drive arm 62 that passes through the driven hole 114. When the slider 61 slides, the drive arm 62 drives the drive rocker arm 10 to swing around the fixing post 43. The drive lever 10 forms a lever structure. The driven hole 114 is located at one end of the drive lever 10, and the drive rod segment 12 is located at the other end of the drive lever 10. The drive arm 62 on the drive member 60 can extend into the driven hole 114 to drive the drive lever 10 to swing, thereby driving the pressure cover 50 to rotate through the drive rod segment 12. The guide groove 42 on the mounting cover 40 can guide the slider 61 of the drive member 60. The fixed post 43 on the mounting cover 40 forms the swing fulcrum of the drive lever 10 (the axis of the fixed post 43 forms the swing center of the drive lever 10), thereby ensuring that the slider 61, the drive lever 10 and the pressure cover 50 can all move according to a predetermined trajectory.

[0070] In this embodiment, the guide groove 42 extends in a straight line, and the driving member 60 and the driving rocker arm 10 are separate structures that are rotatably connected. Of course, in embodiments not shown in the figures, the guide groove can also be an arc-shaped groove, and the driving member and the driving rocker arm can be an integral structure.

[0071] like Figure 1 and Figure 11 As shown, in this embodiment, the driving groove and the driven hole 114 formed between the swing arm 20 and the driving rod segment 12 are both long groove structures extending along the length direction of the driving swing arm 10.

[0072] like Figures 1 to 4 As shown, the drive unit 60 also includes a first coupling portion 63 disposed on the slider 61 and exposed downwards on the mounting cover 40. The first coupling portion 63 is exposed downwards on the mounting cover 40, so that the first coupling portion 63 can be coupled with the coupling structure on the pot body assembly (specifically the second coupling portion 81 mentioned later). This allows the operating component (the user performs the opening operation through the operating component, specifically the screw-operated component 90 mentioned later) to be disposed on the pot body assembly, freeing up the space above the lid assembly to accommodate structures such as the operation panel, thereby improving the user experience.

[0073] It should be noted that the aforementioned "first coupling part 63 protruding downward from the mounting cover 40" is not limited to the first coupling part 63 extending downward from the mounting cover 40. For example, an opening structure is provided on the mounting cover, the first coupling part is located above the opening structure, and the coupling structure on the cook body assembly passes through the opening structure to the top of the mounting cover and couples with the first coupling part; or the first coupling part and the second coupling part are magnetic coupling structures, in which case the first coupling part can be located above the mounting cover and there is no need to provide an opening structure on the mounting cover.

[0074] In an embodiment not shown in the figure, the first coupling part may be omitted, and the operating element may be directly placed on the cover assembly.

[0075] like Figures 5 to 18 As shown, this application also provides a cooking appliance. An embodiment of the cooking appliance of this application includes a lid assembly, which is the lid assembly described above. The lid assembly described above can effectively solve the problem of cumbersome lid opening operations in related technologies, and the cooking appliance having the lid assembly described above also has the aforementioned advantages.

[0076] like Figure 2 , Figure 5 and Figure 6 As shown, the cooking appliance includes a pot body assembly and a lid assembly that can be opened and closed over the pot body assembly. The lid assembly is the aforementioned lid assembly. The pot body assembly includes a housing 70 and a sliding member 80. The sliding member 80 is slidably disposed on the housing 70 and has a second coupling portion 81 protruding upward from the housing 70. The second coupling portion 81 can cooperate with the first coupling portion 63 and drive the slider 61 to slide. The second coupling portion 81 of the sliding member 80 cooperates with the first coupling portion 63 to drive the slider 61 to slide, thereby driving the pressure cover 50 to rotate. When it is necessary to open or close the lid, the user only needs to control the sliding member 80 to slide. On the one hand, it allows the operating components to be placed on the pot body assembly, freeing up the space above the lid assembly for a larger control panel or other structures; on the other hand, the user only needs to control the sliding member 80 to slide, which has the advantage of simple operation.

[0077] It should be noted that the above-mentioned "second coupling part 81 protruding upward from the housing 70" is not limited to the second coupling part 81 extending upward from the housing 70. For example, an opening structure is provided on the housing, the second coupling part is located below the opening structure, and the first coupling part provided on the cover assembly passes through the opening structure to the inside of the housing and couples with the second coupling part; or the first coupling part and the second coupling part are magnetic coupling structures, in which case the second coupling part can be provided inside the housing and there is no need to provide an opening structure on the housing.

[0078] like Figure 5 , Figure 6 , Figure 12 and Figure 13 As shown, the pot body assembly includes a pot body 130 and a pressure-bearing member 140. The pot body 130 is disposed inside the housing 70, and the pressure-bearing member 140 is disposed between the pot body 130 and the housing 70 and has pot teeth that mate with the cover teeth on the pressure-bearing cover 50.

[0079] like Figure 5 and Figure 6 As shown, the housing 70 includes an outer shell 71 and a middle plate 72 disposed above the outer shell 71. The sliding member 80 includes a first sliding portion 82 located below the middle plate 72 and a second sliding portion 83 located above the middle plate 72 and fixedly connected to the first sliding portion 82. A second coupling portion 81 is disposed on the second sliding portion 83. By configuring the sliding member 80 as a split structure and placing the second sliding portion 83 with the second coupling portion 81 above the middle plate 72, that is, placing the second coupling portion 81 above the housing 70, coupling between the first coupling portion 83 and the second coupling portion 81 can be easily achieved.

[0080] like Figure 5 As shown, the housing 70 also includes a base 74 disposed below the housing 71.

[0081] like Figure 4 and Figure 9 As shown, the first coupling part 63 includes a coupling post 631 disposed on the slider 61 and extending downward from the mounting cover 40, and the second coupling part 81 includes a coupling groove 811 disposed on the second sliding part 83. When the cover assembly is closed on the pot body assembly, the coupling post 631 is inserted into the coupling groove 811. The sliding member 80 drives the driving member 60 to move through the cooperation between the coupling post 631 and the coupling groove 811, which has the advantage of simple structure.

[0082] like Figure 9 , Figure 12 , Figure 14 and Figure 16 As shown, the middle plate 72 is provided with a mounting protrusion 721, and the mounting protrusion 721 is provided with a mounting opening 7211. The second sliding part 83 is slidably disposed above the mounting protrusion 721 and blocks the mounting opening 7211. The sliding member 80 also includes a connecting arm 84 that passes through the mounting opening 7211 and connects the first sliding part 82 and the second sliding part 83. Providing the mounting protrusion 721 on the middle plate 72 can raise the position of the second sliding part 83, thereby reducing the length of the coupling post 631. The first sliding part 82 and the second sliding part 83 are fixedly connected by the connecting arm 84, which has the advantage of simple structure.

[0083] like Figure 16 As shown, the connecting arm 84 is disposed on the second sliding portion 83 and extends downward. Figure 14As shown, the first sliding part 82 is provided with a connecting groove 822 for the lower end of the connecting arm 84 to be inserted. The first sliding part 82 is also provided with a guide groove 821. Correspondingly, a guide post is provided below the mounting protrusion 721. The guide post passes through the guide groove 821 to guide the sliding of the sliding member 80.

[0084] Specifically, the aforementioned "second sliding part 83 sealing the mounting opening 7211" refers to the second sliding part 83 sealing the mounting opening 7211 when the lid assembly is not closed on the pot body assembly. Since the upper part of the pot body assembly is exposed at this time, the second sliding part 83 sealing the mounting opening 7211 can prevent the user from seeing the mounting opening 7211, thus improving the user experience; in addition, it can also prevent dirt and other contaminants from entering the interior of the housing 70 through the mounting opening 7211. Since it is necessary to avoid the sliding of the first sliding member 80, the mounting opening 7211 needs to have a certain length. When the lid assembly is placed on the pot body assembly and the pot teeth and lid teeth are aligned, and the hook structure is in the hook state, the second sliding part 83 can not block the mounting opening 7211.

[0085] like Figures 5 to 7 , Figure 14 and Figure 17 As shown, the cooker body assembly also includes a rotating operating component 90 exposed outside the outer casing 71. The rotating operating component 90 is provided with a driving tooth 91, and the first sliding part 82 is provided with a driven tooth 85 that meshes with the driving tooth 91, so that the rotating operating component 90 rotates to drive the first sliding part 82 to move. Setting the operating component as a rotating operating component 90 is adapted to the user's usage habits and facilitates user operation. The rotation of the rotating operating component 90 is converted into the sliding of the sliding component 80 through the cooperation between the driving tooth 91 and the driven tooth 85, which has the advantages of simple structure and reliable transmission.

[0086] It should be noted that the above-mentioned "twisting operation component 90 protruding from the housing 71" is not limited to the twisting operation component 90 extending outward from the housing 71. The knob operation component may also not protrude from the housing, and an operating recess may be provided on the housing for the user to reach into and operate the twisting operation component.

[0087] like Figure 5 , Figure 6 and Figure 17 As shown, the housing 71 has a mounting hole 711, and the housing 70 also includes a mounting base 73 disposed at the mounting hole 711. The screwing operation component 90 includes a knob 92 and a drive wheel 93. The knob 92 is rotatably mounted on the mounting base 73 and extends outward from the housing 71. The drive wheel 93 is located inside the housing 71 and is fixedly connected to the knob 92. The drive gear 91 is disposed on the drive wheel 93. By setting the screwing operation component 90 as a split structure and providing a mounting base 73 on the housing 71, it is convenient to install the screwing operation component 90 onto the housing 71.

[0088] like Figure 5 , Figure 6 and Figure 17 As shown, the mounting cover 40 is provided with a first hook 44, and the middle plate 72 is movably provided with a second hook 100. When the cover assembly is placed on the pot body assembly, the second hook 100 has a latching position that engages with the first hook 44 and a release position that is separated from the first hook 44. The rotating operating member 90 has a second push top 94. When the rotating operating member 90 drives the drive rocker arm 10 to swing between the closed position and the disengaged position via the sliding member 80 and the slider 61, the second push top 94 separates from the second hook 100. When the rotating operating member 90 drives the drive rocker arm 10 to swing from the disengaged position to the release position via the sliding member 80 and the slider 61, the second push top 94 pushes the second hook 100, causing the second hook 100 to switch from the latching position to the release position. The first hook 44 and the second hook 100 form a hook-and-loop structure between the cover assembly and the pot body assembly. During the rotation of the screw-operated component 90, the position of the second push top 94 set on it will change. By reasonably setting the position of the second push top 94, when the drive lever 10 swings from the disengaged position to the disengaged position, the second push top 94 will push the second hook 100, realizing the disengagement between the second hook 100 and the first hook 44. This can realize the disengagement of the teeth first and then the disengagement during the opening process, avoiding the situation where the lid assembly flips up when the pot teeth and lid teeth still have overlapping parts, causing the pot teeth and lid teeth to have a rigid collision.

[0089] Specifically, such as Figure 17 As shown, in this embodiment, the second push top 94 is located at the end of the drive wheel 93 away from the knob 92. The second push top 94 has a guide slope to ensure that during the swing of the drive lever 10 from the disengaged position to the disengaged position, the second push top 94 can gradually push the second hook 100 to achieve disengagement.

[0090] Of course, in the embodiment not shown in the figure, the push-top structure that drives the second hook to switch states can also be set on the slider. Specifically, the slider has a first push-top. When the slider drives the drive lever to swing between the closed position and the disengaged position through the slider, the first push-top separates from the second hook. When the slider drives the drive lever to swing from the disengaged position to the disengaged position through the slider, the first push-top pushes the second hook and causes the second hook to switch from the engaged position to the disengaged position.

[0091] like Figure 5 and Figure 18As shown, in this embodiment, the second hook 100 is a swing rod structure. The second hook 100 includes a hook body 101, a pivot 102, a push top 103, and a reset member. The hook body 101 and the push top 103 are located on both sides of the pivot 102. The second hook 100 is swayably mounted on the middle plate 72 through the pivot 102. When the second hook 100 is in the latching position, the hook body 101 hooks with the first hook 44, and the second push top 94 engages with the push top 103. The reset member is disposed between the hook body 101 and the middle plate 72 and applies a force to the hook body 101 so that the second hook 100 remains in the latching position when no external force is applied.

[0092] like Figure 18 As shown, the push top 103 has a mating ramp that extends towards the screwing operating member 90 in a top-to-bottom direction. During the swinging motion of the drive lever 10 from the disengaged position to the disengaged position, the second push top 94 first abuts against the upper end of the mating ramp, and then against the lower end of the mating ramp, causing the second hook 100 to... Figure 18 The mechanism swings clockwise to disengage the second hook 100 from the first hook 44. When the opening operation is completed and the user no longer operates the screwing mechanism 90, the reset mechanism applies a reset force to the second hook 100, causing the second hook 100 to switch from the unhooked position to the hooked position. At this time, the cooperating inclined surface applies a force to the second push top 94, causing the screwing mechanism 90 to rotate a certain angle.

[0093] Of course, in the embodiment not shown in the figure, the second hook can also be set on the translation member, and the second hook can be engaged or disengaged from the first hook through translational movement; or, the first hook can be set as a movable member and the second hook as a fixed member, and a third push top can be set on the driving swing rod or the driving member. When the driving swing rod swings from the disengaged position to the disengaged position, the third push top pushes the first hook, causing the first hook and the second hook to disengage from the hook-and-loop engagement state, thereby realizing the opening of the cover.

[0094] like Figure 5 , Figure 12 , Figure 13 and Figure 16As shown, the pot body assembly also includes a locking member 110 disposed on the housing 70. The locking member 110 has a locked position and an unlocked position. The locking member 110 includes a locking rod 1101 and a trigger rod 1102. When the lid assembly is not closed on the pot body assembly, the locking member 110 is in the locked position, the trigger rod 1102 extends upward through the housing 70, and the locking rod 1101 locks the sliding member 80. When the lid assembly is closed on the pot body assembly, the lid assembly presses down the trigger rod 1102 and drives the locking member 110 to switch from the locked position to the unlocked position, and the locking rod 1101 unlocks the sliding member 80. When the lid assembly is not closed onto the pot body assembly, the locking lever 1101 locks the sliding member 80 in a position that positions the drive rocker arm 10 in the disengaged position. Thus, during the process of closing the lid assembly onto the pot body assembly, even if the pressure cover 50 rotates in the open state, the first coupling part 63 needs to couple with the second coupling part 81. During the alignment process, the pressure cover 50 will rotate to a position where the lid teeth and pot teeth are misaligned, thus preventing the pot teeth and lid teeth from colliding. After the lid assembly is closed onto the pot body assembly, the locking lever 1101 unlocks the sliding member 80, allowing the sliding member 80 to slide to perform the alignment, disengagement, or release operations of the lid assembly and pot body assembly.

[0095] Specifically, such as Figure 12 , Figure 13 and Figure 16 As shown, the mounting protrusion 721 is provided with a first through hole through which the locking rod 1101 passes upward and a second through hole through which the trigger rod 1102 passes upward. The second sliding part 83 is provided with a locking groove 831 and a clearance notch for avoiding the trigger rod 1102. When the cover assembly is not closed on the pot body assembly, both the locking rod 1101 and the trigger rod 1102 pass upward through the mounting protrusion 721, and the locking rod 1101 passes through the first through hole and extends into the locking groove 831, thereby locking the sliding member 80. When the cover assembly is closed on the pot body assembly, the cover assembly presses down on the trigger rod 1102, causing the locking member 110 to move downward as a whole, the locking rod 1101 disengages from the locking groove 831, and the sliding member 80 can slide.

[0096] like Figure 15As shown, the locking component 110 comprises two separate parts. Component one includes a locking rod 1101, a trigger rod 1102, and a guide rod 1103. The locking rod 1101 and the trigger rod 1102 extend upwards, and the guide rod 1103 extends downwards. Component two includes a mounting plate 1104 and a guide hole 1105 provided on the mounting plate 1104. The mounting plate 1104 is fixedly connected to the middle plate 72. The guide rod 1103 passes through the guide hole 1105, allowing component one to move vertically under the guidance of the guide hole 1105 to lock or unlock the sliding component 80. An elastic abutment is provided between the mounting plate 1104 and component one. The elastic abutment applies a resisting force to component one so that the locking component 110 remains in the locked position when no external force is applied (i.e., when the cover assembly does not press down on the trigger rod 1102).

[0097] To facilitate the alignment between the first coupling part 63 and the second coupling part 81 during the closing process, such as Figure 4 As shown, the lower end of the coupling post 631 is provided with a guide slope. Even if there is a certain misalignment between the coupling post 631 and the coupling groove 811, the guide slope can still drive the driving component 60 to move to the position where the coupling post 631 and the coupling groove 811 are directly opposite each other.

[0098] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention 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 invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0099] 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.

[0100] 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 should not be construed as limiting the scope of protection of this invention.

[0101] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
