Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a cooking utensil. Background Art

[0002] In the related art, the lid opening and closing operating member of the pressure cooking appliance is generally a handle member provided on the lid assembly, and the user can open and close the lid by rotating the handle member.

[0003] Since the handle occupies a large space above the cover assembly, the interactive interface needs to be provided on the cover assembly or only a small interactive interface can be provided on the cover assembly, which affects the user experience.

[0004] In addition, arranging the handle on the cover assembly makes the overall height of the cooking utensil higher, which affects the packaging and transportation of the cooking utensil. Utility Model Content

[0005] The main purpose of the present invention is to provide a cooking utensil to solve the problem of poor user experience in the related art.

[0006] In order to achieve the above-mentioned objectives, the present invention provides a cooking utensil, comprising: a pot body assembly, comprising a shell and an operating knob and a first rotating coupling mounted on the shell, the operating knob extending in a horizontal direction and exposed outwardly from the shell, the first rotating coupling extending in a vertical direction and exposed upward from the shell, and when the operating knob is rotated, the first rotating coupling is driven to rotate; a cover body assembly, comprising a mounting cover, a locking member mounted on the mounting cover, and a second rotating coupling mounted on the mounting cover, the locking member having a locking position for locking the pot body assembly and an unlocking position for unlocking the pot body assembly, the second rotating coupling being exposed downward from the mounting cover and capable of coupling with the first rotating coupling to rotate synchronously with the first rotating coupling, and when the second rotating coupling rotates, it can drive the locking member to switch between the locked position and the unlocked position.

[0007] According to the technical solution of the present invention, the pot body assembly includes an operating knob and a first rotating coupling, and the lid assembly includes a second rotating coupling. When the operating knob is rotated, the first rotating coupling is driven to rotate, and when the first rotating coupling is rotated, the second rotating coupling is driven to rotate synchronously, and when the second rotating coupling is rotated, the locking member is driven to switch between a locked position and an unlocked position. By arranging the operating knob on the housing of the pot body assembly and arranging the first rotating coupling and the second rotating coupling between the operating knob and the locking member, the force applied by the user to the operating knob can be transmitted to the locking member and drive the locking member to switch positions. The above arrangement realizes the arrangement of the operating knob on the pot body assembly, thereby freeing up the space above the lid assembly, which can be used to set up a larger interactive interface and facilitate user use. Therefore, the technical solution of the present application can effectively solve the problem of poor user experience in the related art.

[0008] Furthermore, one of the first and second rotating couplings is provided with a slot, and the other of the first and second rotating couplings is provided with an insertion protrusion, and the slot and the insertion protrusion have a unique mating state. This arrangement can avoid situations where the first and second rotating couplings can be plugged in, but when the cover assembly is pressed down, the pot teeth and the cover teeth partially overlap, affecting further downward pressure of the cover assembly; or situations where the first and second rotating couplings can be plugged in, but after the user rotates the operating knob to a set rotation angle, the pot teeth and the cover teeth partially align, resulting in the pressure bearing capacity between the pot teeth and the cover teeth not meeting the requirements.

[0009] Furthermore, the plug-in protrusion includes a first protrusion and a second protrusion, the first protrusion and the second protrusion have different cross-sections, and the slot has a first groove for the first protrusion to be inserted into and a second groove for the second protrusion to be inserted into. This arrangement ensures that the first rotating coupling and the second rotating coupling have a unique mating state, which has the advantage of a simple structure.

[0010] Furthermore, the plug-in protrusion and the slot have the same preset cross-section, and the shape of the preset cross-section is D-shaped, trapezoidal, T-shaped or non-equilateral triangle. Through the above arrangement, the first rotating coupling member and the second rotating coupling member have a unique matching state, which has the advantage of simple structure.

[0011] Furthermore, the operating knob is provided with a first transmission tooth, and the first rotary coupling is provided with a second transmission tooth that meshes with the first transmission tooth. The mutually meshing first and second transmission teeth convert rotation of the operating knob about the transverse axis into rotation of the first rotary coupling about the vertical axis, thereby achieving the advantages of simple structure and reliable transmission.

[0012] Furthermore, the first transmission teeth include a plurality of first teeth disposed on the inner end surface of the operating knob. The plurality of first teeth are arranged circumferentially and extend radially of the operating knob, with the cross-sectional dimensions of each first tooth gradually increasing in a direction away from the centerline of the operating knob. The second transmission teeth include a plurality of second teeth disposed on the outer periphery of the first rotary coupling, with the plurality of second teeth extending axially of the first rotary coupling. By gradually increasing the cross-sectional dimensions of the first teeth from the centerline of the operating knob toward the outer side, rotation of the operating knob about the transverse axis can be converted into rotation of the first rotary coupling about the vertical axis.

[0013] Furthermore, the housing includes an outer shell and a middle plate disposed above the outer shell. The middle plate is provided with a lower coupling seat and a lower mounting cylinder. The lower coupling seat is provided with an upper protrusion and has a mounting hole. The lower mounting cylinder is disposed below the lower coupling seat and communicates with the mounting hole and has a lateral opening. The first rotary coupling member is mounted within the mounting space formed by the mounting hole and the lower mounting cylinder. The second transmission tooth is exposed from the lower mounting cylinder through the lateral opening to engage with the first transmission tooth. The lower mounting cylinder is capable of mounting and supporting the first rotary coupling member. The lateral opening allows the second transmission tooth to be exposed, thereby enabling engagement between the first transmission tooth and the second transmission tooth.

[0014] Furthermore, the locking member is a locking cover rotatably disposed below the mounting cover. The second rotating coupling member includes a coupling portion and a rocker portion. The coupling portion is coupled to the first rotating coupling member and is capable of driving the rocker portion to swing. The locking member includes a cover body and a drive post disposed on the cover body. The rocker portion is provided with a drive hole, and the drive post is inserted through the drive hole. When the rocker portion swings, the drive post drives the cover body to rotate. The coupling portion is coupled to the first rotating coupling member to transmit the driving force from the pot body assembly to the cover body assembly. When the coupling portion rotates, the drive post inserted through the drive hole drives the drive post to swing, thereby driving the locking cover to rotate.

[0015] Furthermore, the cover assembly also includes a first hook provided on the mounting cover, and the pot body assembly also includes a second hook movably mounted on the shell, the second hook having a fastening position cooperating with the first hook and an unfastening position separated from the first hook, and the operating knob includes a knob portion and a pressing portion movably provided on the knob portion, the pressing portion being able to press against the second hook to switch the second hook from the fastening position to the unfastening position. The operating knob includes a knob portion and a pressing portion movably provided on the knob portion, and the user can drive the locking member to switch between the locked position and the unlocked position by rotating the knob portion, and can drive the second hook to switch from the fastening position to the unfastening position by pressing the pressing portion, so that the user can realize two locking adjustments at the operating knob, which is convenient for the user.

[0016] Furthermore, the pot body assembly also includes a first retaining member, which is arranged between the second hook and the shell to keep the second hook in the engaged position; and / or the operating knob also includes a second retaining member arranged between the knob portion and the pressing portion, and the second retaining member applies a force toward the outside of the shell to the pressing portion to keep the pressing portion in a position separated from the second hook. The provision of the first retaining member can achieve automatic engagement between the first hook and the second hook during the lid closing process. After the user presses the pressing portion, the pressing portion can automatically reset under the action of the second retaining member, making it convenient for the user to press the pressing portion next time.

[0017] Furthermore, the second hook, the first rotary coupling, and the operating knob are arranged sequentially from the inside of the housing to the outside of the housing; and / or the second hook is swingably mounted on the housing. This arrangement enables the operating knob to simultaneously drive the first rotary coupling and the second hook while ensuring a compact structure. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0055] Figures 1 to 11 A schematic structural diagram of a first embodiment of a cooking appliance according to the present application is shown.

[0056] like Figures 1 to 4As shown, a first embodiment of the cooking appliance of the present application includes a pot assembly and a lid assembly. The pot assembly includes a housing 10, an operating knob 20 mounted on the housing 10, and a first rotating coupling 30. The operating knob 20 extends horizontally and is exposed outward from the housing 10. The first rotating coupling 30 extends vertically and is exposed upward from the housing 10. Rotation of the operating knob 20 drives the first rotating coupling 30 to rotate. The lid assembly includes a mounting cover 40, a locking member 50 mounted on the mounting cover 40, and a second rotating coupling 60 mounted on the mounting cover 40. The locking member 50 has a locked position for locking the pot assembly and an unlocked position for unlocking the pot assembly. The second rotating coupling 60 is exposed downward from the mounting cover 40 and can couple with the first rotating coupling 30 to rotate synchronously with the first rotating coupling 30. Rotation of the second rotating coupling 60 drives the locking member 50 to switch between the locked and unlocked positions.

[0057] Using the technical solution of this embodiment, the pot body assembly includes an operating knob 20 and a first rotating coupling 30, and the lid assembly includes a second rotating coupling 60. Rotating the operating knob 20 drives the first rotating coupling 30 to rotate, which in turn drives the second rotating coupling 60 to rotate synchronously. Rotating the second rotating coupling 60 drives the locking element 50 to switch between a locked position and an unlocked position. By positioning the operating knob 20 on the pot body assembly housing 10 and disposing the first rotating coupling 30 and the second rotating coupling 60 between the operating knob 20 and the locking element 50, the force applied by the user to the operating knob 20 is transmitted to the locking element 50, driving the locking element 50 to switch positions. This arrangement allows the operating knob to be positioned on the pot body assembly, freeing up space above the lid assembly for a larger interactive interface and facilitating user experience. Therefore, the technical solution of this embodiment effectively addresses the poor user experience issue in related technologies.

[0058] In addition, in this embodiment, the operating knob 20 for the user to operate to open the lid is set on the pot body assembly, so that the top of the lid assembly is a flat structure with a more beautiful appearance, and the overall height of the cooking appliance is relatively low, reducing transportation costs.

[0059] It should be noted that the aforementioned "exposed operation knob 20" is not limited to the operation knob 20 extending outward from the housing 10. The outer end of the operation knob may not protrude from the housing, and a recessed portion may be provided on the housing for the user to insert their hand to rotate the operation knob. When the outer end of the operation knob does not protrude from the housing, the outer surface of the housing remains smooth and free of noticeable protrusions, enhancing the overall aesthetics of the pot assembly and reducing the possibility of the user accidentally touching the operation knob during cooking.

[0060] It should be noted that the aforementioned “first rotary coupling 30 upwardly exposed from the housing 10” and “second rotary coupling 60 downwardly exposed from the mounting cover 40” are not limited to the form of “penetrating”. For example, a first opening corresponding to the first rotary coupling may be provided on the housing, and a second opening corresponding to the second rotary coupling may be provided on the mounting cover, wherein the first rotary coupling extends upward from the first opening, and the second rotary coupling is entirely located above the second opening. When the cover assembly is placed on the pot assembly, the first rotary coupling extends into the second opening to couple with the second rotary coupling. Alternatively, a first opening corresponding to the first rotary coupling may be provided on the housing, and a second opening corresponding to the second rotary coupling may be provided on the mounting cover, wherein the first rotary coupling is entirely located below the first opening, and the second rotary coupling extends downward from the second opening. When the cover assembly is placed on the pot assembly, the second rotary coupling extends into the first opening to couple with the first rotary coupling. Alternatively, the first rotary coupling and the second rotary coupling may be synchronously rotated by magnetic coupling, and the first rotary coupling does not extend upward from the housing, and the second rotary coupling does not extend downward from the mounting cover.

[0061] The above-mentioned "horizontal direction" is not limited to the horizontal direction, but can also be a direction having a certain angle (for example, 0° to 15°) with the horizontal direction; the above-mentioned "vertical direction" is not limited to the vertical direction, but can also be a direction having a certain angle (for example, 0° to 15°) with the vertical direction.

[0062] Specifically, in this embodiment, the locking member 50 is provided with a cover tooth, and the pot body assembly includes a pot body 110 having pot teeth. When the locking member 50 is in the locked position, the pot teeth and the cover teeth overlap in the up and down directions. When the locking member 50 is in the unlocked position, the pot teeth and the cover teeth are misaligned in the circumferential direction (in this case, the locking member is a locking cover) or misaligned in the radial direction (in this case, the locking member is a caliper).

[0063] like Figure 1 、 Figure 2 、 Figure 9 and Figure 10As shown, one of the first and second rotating couplings 30, 60 is provided with a slot 71, and the other of the first and second rotating couplings 30, 60 is provided with an insertion protrusion 72. The slot 71 and the insertion protrusion 72 have a unique mating state. It should be noted that this "unique mating state" means that the first and second rotating couplings 30, 60 have only one mating state within a 360-degree range. When the first and second rotating couplings 30, 60 are at other angles, the insertion protrusion cannot be inserted into the slot 71. Since the first and second rotary couplings 30 and 60 are rotating members, by properly configuring the first rotary coupling 30's posture when the lid assembly is not closed on the pot body assembly, during the process of pressing the lid assembly downward, the second rotary coupling 60 can only couple with the first rotary coupling 30 when it is rotated to a specific posture. This ensures that the pot teeth and the cover teeth are misaligned when the lid assembly is pressed downward, and also ensures that when the user subsequently rotates the operating knob 20 at a specified rotation angle to switch the position of the locking member 50, the cover teeth and the pot teeth are properly aligned, that is, the locking member 50 smoothly switches from the unlocked position to the locked position. This avoids the situation where the first and second rotary couplings can be plugged in, but the pot teeth and the cover teeth partially overlap when the lid assembly is pressed downward, affecting further downward pressure of the lid assembly, or the situation where the first and second rotary couplings can be plugged in, but after the user rotates the operating knob at the specified rotation angle, the pot teeth and the cover teeth partially align, resulting in the pot teeth and the cover teeth not meeting the required pressure bearing capacity.

[0064] like Figure 9 and Figure 10 As shown, in this embodiment, the insertion protrusion 72 includes a first protrusion 721 and a second protrusion 722. The first protrusion 721 and the second protrusion 722 have different cross-sections, and the slot 71 has a first groove 711 for inserting the first protrusion 721 and a second groove 712 for inserting the second protrusion 722. This arrangement ensures that the first rotating coupling 30 and the second rotating coupling 60 have a unique mating state, which has the advantage of a simple structure.

[0065] It should be noted that the above “the first protrusion 721 and the second protrusion 722 have different cross sections” refers to that the cross sections of the first protrusion 721 and the second protrusion 722 have different sizes and / or shapes.

[0066] In this embodiment, the first protrusion 721 has a square cross-section, while the second protrusion 722 has a partial circular cross-section. The side surfaces of the first and second protrusions 721 and 722 are connected. Of course, in embodiments not shown, the first and second protrusions can have other shapes, and the side surfaces of the first and second protrusions can be disconnected, as long as the first and second rotating couplings can be uniquely mated. Alternatively, the insertion protrusion 72 and the slot 71 can have the same predetermined cross-section, which can be a D-shape, trapezoid, T-shape, or a non-equilateral triangle.

[0067] like Figure 1 、 Figure 10 and Figure 11 As shown, the operating knob 20 is provided with a first transmission tooth 81, and the first rotary coupling member 30 is provided with a second transmission tooth 82 that meshes with the first transmission tooth 81. The mutually meshing first transmission teeth 81 and second transmission teeth 82 are used to convert the rotation of the operating knob 20 about the horizontal axis into the rotation of the first rotary coupling member 30 about the vertical axis, thereby having the advantages of simple structure and reliable transmission.

[0068] like Figure 1 、 Figure 10 and Figure 11 As shown, the first transmission teeth 81 include a plurality of first teeth 811 disposed on the inner end surface of the operating knob 20. The plurality of first teeth 811 are arranged along the circumference of the operating knob 20 and extend in the radial direction of the operating knob 20. The cross-sectional dimension of each first tooth 811 gradually increases in the direction away from the centerline of the operating knob 20. The second transmission teeth 82 include a plurality of second teeth 821 disposed on the outer circumference of the first rotary coupling 30. The plurality of second teeth 821 extend in the axial direction of the first rotary coupling 30. By gradually increasing the cross-sectional dimension of the first teeth 811 in the direction from the centerline of the operating knob 20 to the outside, the rotation of the operating knob 20 about the transverse axis can be converted into the rotation of the first rotary coupling 30 about the vertical axis.

[0069] It should be noted that the above-mentioned “multiple first teeth 811 are arranged along the circumferential direction of the operating knob 20 ” can mean that the multiple first teeth 811 are arranged in a full circle along the circumferential direction, or that the multiple first teeth 811 are arranged in an arc-shaped trajectory along the circumferential direction.

[0070] Of course, in an embodiment not shown in the figure, the first transmission tooth can be a first bevel gear structure arranged on the inner end face of the operating knob, and the second transmission tooth can be a second bevel gear structure arranged at the lower end of the first rotating coupling member, and the first bevel gear structure and the second bevel gear structure cooperate to achieve a change in the rotation direction.

[0071] like Figure 2 、 Figure 4 and Figure 7 As shown, the housing 10 includes an outer shell 11 and a middle plate 12 disposed above the outer shell 11. The middle plate 12 is provided with a lower coupling seat 121 and a lower mounting cylinder 122. The lower coupling seat 121 is provided with a protruding upper portion and has a mounting hole 123. The lower mounting cylinder 122 is disposed below the lower coupling seat 121 and communicates with the mounting hole 123 and has a lateral opening 1221. The first rotary coupling member 30 is mounted within the mounting space formed by the mounting hole 123 and the lower mounting cylinder 122. The second transmission tooth 82 is exposed from the lower mounting cylinder 122 through the lateral opening 1221 to engage with the first transmission tooth 81. The lower mounting cylinder 122 can be used to mount and support the first rotary coupling member 30. The lateral opening 1221 allows the second transmission tooth 82 to be exposed, thereby enabling engagement between the first transmission tooth 81 and the second transmission tooth 82.

[0072] Specifically, if Figure 4 As shown, the lower mounting cylinder 122 has a lower end plate with a mounting hole. The lower end of the first rotating coupling 30 is rotatably inserted into the mounting hole, and the lower end plate is supported below the first transmission tooth 81. A stopper can be connected to the lower end of the first rotating coupling 30 to prevent the first rotating coupling 30 from being pulled upward out of the lower coupling seat 121 due to the coupling connection between the first rotating coupling 30 and the second rotating coupling 60 when the cover is opened.

[0073] like Figure 1 As shown, the housing 10 further includes a bottom shell 13 disposed below the outer shell 11. The pot body 110 is disposed in a space enclosed by the outer shell 11, the middle plate 12 and the bottom shell 13. The cover assembly further includes a surface cover 100 disposed above the mounting cover 40.

[0074] like Figure 1 and Figure 2 As shown, the housing 11 is provided with a mounting opening 111, and the pot body assembly further includes a mounting seat 14 provided at the mounting opening 111. The operating knob 20 is passed through the mounting seat 14 and is mounted on the housing 11 through the mounting seat 14. The mounting seat 14 is engaged with the side wall of the mounting opening 111.

[0075] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the locking member 50 is a locking cover rotatably disposed below the mounting cover 40. The second rotating coupling member 60 includes a coupling portion 61 and a rocker portion 62. The coupling portion 61 is coupled to the first rotating coupling member 30 and can drive the rocker portion 62 to swing. The locking member 50 includes a cover body 51 and a driving post 52 disposed on the cover body 51. The rocker portion 62 is provided with a driving hole 621, and the driving post 52 is inserted into the driving hole 621. When the rocker portion 62 swings, the driving post 52 drives the cover body 51 to rotate. The coupling portion 61 is coupled to the first rotating coupling member 30 to transmit the driving force from the pot body assembly to the cover body assembly. When the coupling portion 61 rotates, the driving post 52 inserted into the driving hole 621 drives the driving post 52 to swing, thereby driving the locking cover to rotate, thereby enabling the locking cover to switch between a locked position and an unlocked position.

[0076] like Figure 1 、 Figure 9 and Figure 10 As shown, the plug-in protrusion 72 is provided at the lower end of the coupling portion 61 , and the slot 71 is provided on the upper surface of the first rotating coupling 30 , so that the second rotating coupling 60 can be driven to rotate synchronously when the first rotating coupling 30 rotates.

[0077] like Figure 5 and Figure 6 As shown, the mounting cover 40 is provided with an arcuate slot 41, the rocker portion 62 is located above the mounting cover 40, and the locking member 50 is located below the mounting cover 40. The drive post 52 passes through the arcuate slot 41 from bottom to top and extends into the drive hole 621 of the rocker portion 62. When the rocker portion 62 swings, the drive post 52 also swings. The drive hole 621 is a long slot structure that can avoid the radial movement of the drive post 52 in the cover assembly during its swinging process.

[0078] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the mounting cover 40 also includes an upper coupling seat 42 and an upper mounting cylinder 43 arranged above the upper coupling seat 42. The upper coupling seat 42 is provided with a mounting hole. The upper mounting cylinder 43 is located at the mounting hole and is connected to the mounting hole. The coupling portion 61 is inserted into the space formed by the mounting hole and the upper mounting cylinder 43. The upper mounting cylinder 43 is supported below the rocker portion 62.

[0079] In this embodiment, the locking member 50 is a locking cover. Of course, in an embodiment not shown in the figure, the locking member can also be a caliper structure, in which case the swing arm portion drives the caliper structure to move horizontally when it swings.

[0080] like Figure 1 as well as Figures 3 to 6As shown, the lid assembly further includes a first hook 91 disposed on the mounting cover 40, and the pot assembly further includes a second hook 92 movably mounted on the housing 10. The second hook 92 has an engaged position in cooperation with the first hook 91 and an unengaged position separated from the first hook 91. The operating knob 20 includes a knob portion 21 and a pressing portion 22 movably disposed on the knob portion 21. The pressing portion 22 can press against the second hook 92 to switch the second hook 92 from the engaged position to the unengaged position. The first hook 91 and the second hook 92 can engage with each other to achieve a double locking between the pot assembly and the lid assembly together with the locking between the pot teeth and the lid teeth. The operating knob 20 includes a knob portion 21 and a pressing portion 22 movably provided on the knob portion 21. The user can drive the locking member 50 to switch between the locked position and the unlocked position by rotating the knob portion 21, and can drive the second hook 92 to switch from the engaged position to the unlocked position by pressing the pressing portion 22, so that the user can realize two locking adjustments at the operating knob 20, which is convenient for the user.

[0081] In this embodiment, the pot assembly further includes a first retaining member disposed between the second hook 92 and the housing 10 to maintain the second hook 92 in the engaged position. When no external force is applied to the second hook 92 (e.g., when the user does not push against the second hook 92 via the pressing portion 22), the second hook 92 remains in the engaged position under the action of the first retaining member. When the lid assembly is pressed down onto the pot assembly from the open position, the first hook 91 and the second hook 92 automatically engage.

[0082] Specifically, in this embodiment, the first hook 91 and the second hook 92 are both provided with a guide slope. When the cover assembly is pressed down, the first hook 91 pushes the second hook 92 outward (that is, toward the Figure 4 The second hook 92 is pushed up from the right side of the retaining member, so that the second hook 92 overcomes the force of the first retaining member and avoids the first hook 91 (that is, the second hook 92 switches from the engaged position to the unengaged position). When the first hook 91 passes over the second hook 92, the second hook 92 is reset to the engaged position under the action of the first retaining member, thereby realizing the automatic engagement between the first hook 91 and the second hook 92, simplifying the user's operation.

[0083] like Figure 8As shown, the second hook 92 is swingably mounted on the housing 10. The second hook 92 includes a hook body 921, a rotation shaft 922, and a push-up fitting portion 923. The hook body 921 and the push-up fitting portion 923 are arranged on both sides of the rotation shaft 922. The second hook 92 is a swinging member that swings around the axis of the rotation shaft 922. The hook body 921 can be hooked and fitted with the first hook 91, and the push-up fitting portion 923 is fitted with the pressing portion 22. When the user presses the pressing portion 22, the pressing portion 22 pushes the push-up fitting portion 923 toward the inside of the pot body assembly, and causes the second hook 92 to swing around the rotation shaft 922 along the Figure 8 The second hook 92 is swung in the clockwise direction so as to switch from the fastened position to the unfastened position.

[0084] like Figure 7 As shown, two fixing plates are spaced apart below the middle plate 12 , and fixing holes 124 are respectively provided on the two fixing plates. The second hook 92 is installed between the two fixing plates, and both ends of the rotating shaft portion 922 are respectively passed through the two fixing holes 124 .

[0085] like Figure 1 、 Figure 3 and Figure 4 As shown, the operating knob 20 further includes a second retaining member 23 disposed between the knob portion 21 and the pressing portion 22. The second retaining member 23 applies a force toward the outside of the housing 10 to the pressing portion 22, so that the pressing portion 22 remains in a position separated from the second hook 92. The second retaining member 23 is disposed between the knob portion 21 and the pressing portion 22 so that after the user presses the pressing portion 22, the pressing portion 22 can automatically return to its original position under the action of the second retaining member 23, making it convenient for the user to press the pressing portion 22 again.

[0086] like Figure 3 As shown, the pressing portion 22 includes a pressing post, an ejection post disposed inside the pressing post, and a hook. The knob portion 21 includes a screw barrel and an inner end plate disposed at the inner end of the screw barrel. The inner end plate is provided with a central mounting hole 211 and a latch hole 212. The pressing post is disposed within the screw barrel, the ejection post is inserted through the central mounting hole 211, and the hook is inserted through and engaged with the latch hole 212. The second retaining member 23 is a compression spring sleeved on the ejection post, with its two ends respectively abutting against the pressing post and the inner end plate. There are two latch hooks and two latch holes 212, each of which is disposed on either side of the ejection post.

[0087] like Figure 4 As shown, the second hook 92, the first rotary coupling 30, and the operating knob 20 are sequentially arranged in a direction from the inside of the housing 10 to the outside of the housing 10. This arrangement ensures that the operating knob 20 can simultaneously drive the first rotary coupling 30 and the second hook 92 while ensuring a compact structure.

[0088] The following describes the movement and transmission relationship of various components during the opening and closing of the lid in conjunction with the specific structure of the cooking appliance:

[0089] In the open state:

[0090] The second hook 92 is kept in the buckled position under the action of the first retaining member; the pressing portion 22 is kept in the unpressed state under the action of the second retaining member 23, the knob portion 21 is kept in the position where the cover teeth on the locking member 50 and the pot teeth on the pot body 110 are misaligned, and the second rotating coupling member 60 is kept Figure 6 In the position shown in FIG, at this time, the driving column 52 is in contact with the left end of the arc-shaped slot 41.

[0091] During the lid closing process:

[0092] The user first presses down the lid assembly so that it approaches the pot body assembly, and the locking member 50 remains in the position where the lid teeth are offset from the pot teeth (when the lid teeth and pot teeth are partially aligned, the user can rotate the locking member 50 to offset the lid teeth from the pot teeth). As a result, the lid assembly can be smoothly pressed down, and the first rotating coupling member 30 and the second rotating coupling member 60 can be smoothly connected. During the process of pressing the lid assembly down, the second hook 92 and the first hook 91 automatically engage under the action of the guiding inclined surface and the first retaining member.

[0093] Then the user can operate the knob 21 to drive the cover teeth and the pot teeth to align. Figure 5 and Figure 6 The knob portion 21 is rotated counterclockwise, and the first transmission tooth 81 on the knob portion 21 engages with the second transmission tooth 82 on the first rotating coupling member 30 to drive the first rotating coupling member 30 to rotate along the Figure 10 The second rotating coupling 60 rotates along with the first rotating coupling 30, and the rocker portion 62 of the second rotating coupling 60 rotates along the Figure 5 and Figure 6 The clockwise swing in the middle drives the driving column 52 from Figure 6 The position of the left end of the arc groove 41 is swung to Figure 5 In the above process, the locking member 50 switches from the unlocking position to the locking position (that is, the cover teeth are switched from the position staggered with the pot teeth to the position facing the pot teeth).

[0094] Through the above steps, when closing the lid, the hook structures between the lid assembly and the pot body assembly are first engaged, and then the pot teeth and the lid teeth are aligned.

[0095] In the closed state:

[0096] The second hook 92 is kept in the fastening position under the action of the first retaining member; the locking member 50 is kept in the position where the cover teeth and the pot teeth are facing each other.

[0097] During the opening process:

[0098] The user first drives the cover teeth and pot teeth to dislocate by turning the knob 21. Figure 5 and Figure 6 The knob portion 21 is rotated clockwise, and the first transmission tooth 81 on the knob portion 21 engages with the second transmission tooth 82 on the first rotating coupling member 30 to drive the first rotating coupling member 30 to rotate along the Figure 10 The second rotating coupling 60 rotates along with the first rotating coupling 30, and the rocker portion 62 of the second rotating coupling 60 rotates along the Figure 5 and Figure 6 The counterclockwise swing in the middle drives the driving column 52 from Figure 5 The position of the arc groove 41 against the right end is swung to Figure 6 In the above process, the locking member 50 switches from the locked position to the unlocked position (that is, the cover teeth are switched from the position facing the pot teeth to the position staggered with the pot teeth).

[0099] Then the user presses the pressing portion 22, the pressing portion 22 overcomes the force of the second retaining member 23, and the pushing column of the pressing portion 22 pushes the pushing matching portion 923 of the second hook 92 inward, so that the second hook 92 overcomes the force of the first retaining member and rotates around the shaft portion 922 along the Figure 4 The lid assembly is automatically flipped open by the cover opening torsion spring provided between the pot body assembly and the lid assembly.

[0100] Through the above steps, when opening the lid, the pot teeth and the lid teeth between the lid assembly and the pot body assembly are firstly disengaged, and then the first hook 91 and the second hook 92 are disengaged.

[0101] Figures 12 to 17 A schematic structural diagram of a second embodiment of a cooking appliance according to the present application is shown.

[0102] The following mainly describes the parts of the second embodiment that are different from the first embodiment, and the same parts of the two embodiments are not repeated.

[0103] like Figure 12 and Figure 13As shown, in this embodiment, the first rotating coupling 30 and the second rotating coupling 60 are both separate structures. Specifically, the first rotating coupling 30 includes a lower gear 31 and a lower coupling portion 32 that are connected to each other to prevent rotation. The lower coupling portion 32 is arranged from top to bottom within the lower mounting tube 122 and engages with a stopper on the upper surface of the lower mounting tube 122. The lower gear 31 is arranged from bottom to top within the lower mounting tube 122 and engages with a stopper on the lower surface of the lower mounting tube 122. The first rotating coupling 30 is configured as a separate lower gear 31 and lower coupling portion 32, and the lower coupling portion 32 and lower gear 31 respectively engage with the upper and lower surface stops of the lower mounting tube 122. This prevents the cover assembly from moving the first rotating coupling 30 downward or upward during the pressing or lifting process, thereby ensuring the installation stability of the first rotating coupling 30. The second rotary coupling 60 includes an upper gear 63 and a coupling portion 61, which are connected to each other in a rotationally fixed manner. The upper gear 63 extends from top to bottom within the upper mounting tube 43 and engages with a stopper on the upper surface of the upper mounting tube 43. The coupling portion 61 extends from bottom to top within the upper mounting tube 43 and engages with a stopper on the lower surface of the upper mounting tube 43. The second rotary coupling 60 is configured as a separate upper gear 63 and coupling portion 61, and the upper gear 63 and coupling portion 61 respectively engage with the upper and lower stoppers on the upper mounting tube 43. This prevents the second rotary coupling 60 from moving upward or downward when the cover assembly is pressed down or lifted, thereby ensuring the installation stability of the second rotary coupling 60. The upper gear 63 is provided with upper driving teeth 631, and the lower gear 31 is provided with lower driven teeth 311.

[0104] like Figures 12 to 15 As shown, the cover assembly further includes a transmission rocker 150 disposed between the second rotating coupling 60 and the locking member 50. The transmission rocker 150 includes a rocker body 151, which is provided with a rotation hole 152, a transmission hole 153, and a drive engagement portion 154. The second rotating coupling 60 is driven in conjunction with the drive engagement portion 154. When the second rotating coupling 60 rotates, the rocker body 151 swings about the axis of the rotation hole 152, thereby driving the drive column 52 to swing. The drive engagement portion 154 is provided with an upper driven tooth 1541 that is capable of meshing with the upper drive tooth 631. When the second rotating coupling 60 rotates, the engagement between the upper drive tooth 631 and the upper driven tooth 1541 drives the rocker body 151 to swing. In this embodiment, a mounting bracket is provided on mounting cover 40. This bracket is supported below rocker body 151 and inserted into rotation hole 152, allowing rocker body 151 to swing about its axis. Transmission hole 153 is located near upper driven tooth 1541. This arrangement allows rocker body 151 to swing through a relatively small angle while still driving locking member 50 to switch positions.

[0105] like Figure 12 、 Figure 14 and Figure 15 As shown, the lid assembly is also provided with an upper locking member 130. When the lid assembly is separated from the pot assembly, the upper locking member 130 locks the transmission rocker 150. The upper locking member 130 can lock the position of the transmission rocker 150 in the lid-open state, thereby maintaining the second rotating coupling member 60 and the locking member 50 in a specific position, ensuring the docking effect of the second rotating coupling member 60 and the first rotating coupling member 30 during the lid-closing process, and the misalignment between the lid teeth and the pot teeth. The upper locking member 130 includes a second trigger portion 131, a mounting tube 132, an elastic member 133, a cantilever 134 and a locking block 135. The second trigger portion 131 and the mounting tube 132 are arranged side by side. The mounting tube 132 has an upper opening. The elastic member 133 is arranged in the mounting tube 132 and applies a downward resisting force to the mounting tube 132. The cantilever 134 is connected to the upper end of the second trigger portion 131. The locking block 135 is arranged below the cantilever 134. A locking hole 155 is provided on the rocker arm body 151. When the cover assembly is not covered on the pot body assembly, the second trigger portion 131 extends downward from the mounting cover 40 under the action of the elastic member 133, and the locking block 135 is inserted into the locking hole 155 to restrict the swing arm body 151 from swinging; when the cover assembly is covered on the pot body assembly, the pot body assembly pushes the second trigger portion 131 upward, causing the upper locking member 130 to move upward as a whole and overcome the resisting force of the elastic member 133, and the locking block 135 disengages from the locking hole 155 upward, allowing the swing arm body 151 to swing.

[0106] like Figure 12 and Figure 16 As shown, in this embodiment, the pot body assembly further includes a translation transmission member 120 disposed between the operating knob 20 and the first rotation coupling member 30. Rotation of the knob portion 21 drives the translation transmission member 120, which in turn drives the lower gear 31. The translation transmission member 120 is disposed between the knob portion 21 and the lower gear 31 and cooperates with both the knob portion 21 and the lower gear 31 to convert rotation of the knob portion 21 about the horizontal axis into rotation of the lower gear 31 about the vertical axis.

[0107] like Figure 13 and Figure 16 As shown, the translation transmission member 120 is provided with a lower driving tooth 126, and the lower gear 31 is provided with a lower driven tooth 311 that meshes with the lower driving tooth 126. The meshing between the lower driving tooth 126 and the lower driven tooth 311 enables the translation transmission member 120 to drive the first rotating coupling member 30 to rotate, which has the advantages of simple structure and reliable transmission.

[0108] like Figure 16As shown, a guide groove 128 is provided on the translation transmission member 120 , and a guide post provided on the middle plate 12 can extend into the guide groove 128 to guide the movement of the translation transmission member 120 .

[0109] like Figure 16 As shown, in this embodiment, a first hook 91 is fixedly mounted on the lid assembly, and a second hook 92 is swingably mounted on the pot assembly. The second hook 92 comprises a pivot portion 922, a hook body portion 921, and a push-up mating portion 923. The pivot portion 922 is hingedly connected to the middle plate 12. The hook body portion 921 and the push-up mating portion 923 are respectively disposed on either side of the pivot portion 922. The hook body portion 921 is capable of engaging with the first hook 91. During the swinging process, the second hook 92 can switch between an engaged position, in which it engages with the first hook 91, and an unengaged position, in which it is separated from the first hook 91. The pot assembly is also provided with a retaining member that applies a force to the second hook 92, thereby maintaining the second hook 92 in the engaged position. When closing the cover, the first hook 91 can push the hook body 921 so that the second hook 92 overcomes the force of the retaining member and switches from the engaged position to the unengaged position. After the first hook 91 passes over the hook body 921, the second hook 92 is reset from the unengaged position to the engaged position under the force of the retaining member, thereby realizing automatic engagement between the first hook 91 and the second hook 92 during the closing process.

[0110] like Figure 16 As shown, the operating knob 20 includes a knob portion 21 and a transmission rod 24 disposed on the knob portion 21. The transmission rod 24 extends toward the interior of the pot body assembly and is disposed offset from the center of the knob portion 21. The translational transmission member 120 is provided with a mating slot 125, and the transmission rod 24 is disposed within the mating slot 125 to drive the translational transmission member 120 to move. The transmission rod 24 is disposed offset from the center of the knob portion 21, so that when a user rotates the knob portion 21, the movement trajectory of the transmission rod 24 is an arcuate or circular trajectory centered on the axis of the knob portion 21. The transmission rod 24 is inserted into the mating slot 125 on the translational transmission member 120, thereby driving the translational transmission member 120 to move.

[0111] like Figure 16As shown, when the lid needs to be opened, the user rotates the knob 21, and the transmission rod 24 on the knob 21 pushes against the push-fitting portion 923 of the second hook 92, causing the second hook 92 to overcome the force of the retaining member and switch from the engaged position to the disengaged position. Specifically, the push-fitting portion 923 is provided with a relief concave surface 9231 and a push-up inclined surface 9232 located below the relief concave surface 9231. The push-up inclined surface 9232 extends toward the outside of the pot body assembly from top to bottom. When the transmission rod 24 is aligned with the relief concave surface 9231, there is a certain distance between the transmission rod 24 and the relief concave surface 9231, and the transmission rod 24 does not push against the second hook 92. When the transmission rod 24 is aligned with the push-up inclined surface 9232, the transmission rod 24 pushes against the push-fitting portion 923 and drives the second hook 92 to swing, thereby achieving the disengagement between the second hook 92 and the first hook 91. By providing an avoidance concave surface 9231 and a push-up inclined surface 9232 on the push-up fitting part 923, the push-up fitting part 923 can avoid part of the stroke of the transmission rod 24, that is, the operation of first stripping and then releasing between the pot body assembly and the cover body assembly can be realized. During this process, the user only needs to turn the knob part 21, which simplifies the user's operating steps and improves the user experience.

[0112] like Figure 16 and Figure 17 As shown, an arc-shaped guide groove 146 is provided on the mounting seat 14 , and the transmission rod 24 of the operating knob 20 is passed through the arc-shaped guide groove 146 . The arc-shaped guide groove 146 can guide and limit the rotation of the transmission rod 24 .

[0113] like Figure 16 As shown, the mating groove 125 of the translation transmission member 120 has a linkage section 1251 and an avoidance section 1252 arranged below the linkage section 1251. When the transmission rod 24 is located in the linkage section 1251, the transmission rod 24 can abut against the side wall of the linkage section 1251 and drive the translation transmission member 120 to move; when the transmission rod 24 is located in the avoidance section 1252, the avoidance section 1252 can avoid the trajectory of the transmission rod 24, that is, the transmission rod 24 can continue to rotate but the translation transmission member 120 will not move.

[0114] Specifically, the linkage section 1251 is configured to correspond to the avoidance concave surface 9231 on the second clasp 92, and the avoidance section 1252 is configured to correspond to the push-up inclined surface 9232 on the second clasp 92. Through the above configuration, when the transmission rod 24 is located in the linkage section 1251, the transmission rod 24 and the translation transmission member 120 drive and cooperate to drive the translation transmission member 120 to move, the transmission rod 24 is corresponding to the avoidance concave surface 9231 and cannot drive the second clasp 92, at this time, the tooth removal operation can be performed, and the second clasp 92 remains in the engaged position; when the transmission rod 24 is located in the avoidance section 1252, the transmission rod 24 and the push-up inclined surface 9232 drive and cooperate to drive the second clasp 92 from the engaged position to the disengaged position, the transmission rod 24 cannot drive the translation transmission member 120 to move, and at this time, the disengagement operation can be performed.

[0115] like Figure 17 As shown, the operating knob 20 further includes a second retaining member 23 disposed between the mounting base 14 and the knob portion 21. When the lid opening operation is completed and the user no longer operates the knob portion 21, the second retaining member 23 applies a restoring force to the transmission rod 24, causing the transmission rod 24 to move from the avoidance section 1252 to the linkage section 1251. At this time, the transmission rod 24 no longer presses against the push-up inclined surface 9232, causing the second hook 92 to return to the engaged position. When the user subsequently closes the lid, the first hook 91 and the second hook 92 can be automatically engaged.

[0116] like Figure 17 As shown, a sinking portion 147 is further provided in the mounting seat 14, and the second retaining member 23 is a torsion spring mounted in the sinking portion 147. The sinking portion 147 is connected to a portion of the arcuate guide groove 146. When the transmission rod 24 is located in the linkage section 1251, the two torsion arms of the torsion spring respectively abut the two side surfaces of the sinking portion 147, and the torsion spring does not apply force to the transmission rod 24. When the transmission rod 24 is located in the avoidance section 1252, one torsion arm of the torsion spring abuts a side wall of the sinking portion 147, and the other torsion arm abuts the transmission rod 24, causing the transmission rod 24 to have a tendency to return to the linkage section 1251.

[0117] like Figure 12 and Figure 16 As shown, the pot body assembly is also provided with a lower locking member 140. When the lid assembly is separated from the pot body assembly, the lower locking member 140 locks the translation transmission member 120. The lower locking member 140 can lock the position of the translation transmission member 120 when the lid is open, thereby maintaining the first rotating coupling member 30 in a specific position, ensuring the effective docking of the second rotating coupling member 60 and the first rotating coupling member 30 during the lid closing process, and the misalignment between the lid teeth and the pot teeth.

[0118] like Figure 16The lower locking member 140 includes a main plate 143, a first trigger portion 141 disposed above the main plate 143, a lock hook portion 142 disposed below the main plate 143, and an elastic member. The lock hook portion 142 has an upwardly opening slot 145. The main plate 143 is provided with a guide hole 144. The middle plate 12 is provided with a guide post that passes through the guide hole 144 to allow the lower locking member 140 to be movable in the vertical direction. The elastic member is mounted on the guide post and presses upward against the lower locking member 140. The translation transmission member 120 is provided with a lock rod 127. When the cover assembly is not closed on the pot body assembly, the elastic member pushes upward against the lower locking member 140, causing the first trigger portion 141 to extend upward from the middle plate 12, and the lock hook portion 142 hooks the lock rod 127 and restricts the lock rod 127 from moving in the lateral direction, that is, restricts the translation transmission member 120 from moving in the lateral direction; when the cover assembly is closed on the pot body assembly, the cover assembly presses down the first trigger portion 141 and overcomes the pushing force of the elastic member, causing the lower locking member 140 to move downward as a whole, that is, the slot 145 moves to the bottom of the lock rod 127, so that the translation transmission member 120 can move in the lateral direction.

[0119] The following describes the movement and transmission relationship of various components during the opening and closing of the lid in conjunction with the specific structure of the cooking appliance:

[0120] In the open state:

[0121] The second hook 92 is maintained in the engaged position under the action of the retaining member; the lower locking member 140 is maintained in the position of locking the translation transmission member 120 under the action of the elastic member, and the locking rod 127 on the translation transmission member 120 is located in the card slot 145 of the lock hook portion 142, limiting the translation transmission member 120 from moving in the lateral direction; the transmission rod 24 is maintained at the intersection of the linkage section 1251 and the avoidance section 1252 under the action of the second retaining member 23; the upper locking member 130 moves downward under the action of the elastic member 133 and causes the transmission rocker 150 to stay in a position where the locking member 50 remains in a position where the cover teeth and the pot teeth are misaligned (that is, the locking member 50 remains in the unlocked position).

[0122] During the lid closing process:

[0123] The user first presses down the cover assembly so that the cover assembly is close to the pot body assembly. Since the locking member 50 is kept in the position where the cover teeth and the pot teeth are misaligned under the action of the upper locking member 130, the cover assembly can be pressed down smoothly. During the process of pressing down the cover assembly, the pot body assembly presses upward against the upper locking member 130, so that the upper locking member 130 switches from the position of locking the transmission rocker 150 to the position of unlocking the transmission rocker 150, and the cover assembly presses downward against the lower locking member 140, so that the lower locking member 140 switches from the position of locking the translation transmission member 120 to the position of unlocking the translation transmission member 120, and the second hook 92 and the first hook 91 on the cover assembly are automatically fastened under the action of the guide slope and the retaining member. At this time, the transmission rod 24 of the operating knob 20 is located at the intersection of the linkage section 1251 and the avoidance section 1252.

[0124] Then the user can operate the knob 20 to align the cover teeth and the pot teeth. Figure 16 The knob portion 21 is rotated clockwise in the middle, and the transmission rod 24 moves clockwise along the arc-shaped guide groove 146. At this time, the transmission rod 24 and the Figure 16 The right side wall of the middle linkage section 1251 cooperates to drive the translation transmission member 120 to Figure 16 The lower driving tooth 126 on the translation transmission member 120 engages with the lower driven tooth 311 on the lower gear 31, driving the lower gear 31, the lower coupling portion 32, the coupling portion 61 and the upper gear 63 to move synchronously along Figure 13 The upper driving tooth 631 of the upper gear 63 meshes with the upper driven tooth 1541 on the transmission rocker 150, driving the transmission rocker 150 to swing along the center of the rotating hole 152. Figure 14 During the swinging process of the transmission rocker 150, the locking member 50 is driven to rotate by the cooperation between the driving column 52 and the transmission hole 153, so that the locking member 50 is rotated from the position where the pot teeth and the lid teeth are staggered to the position where the pot teeth and the lid teeth are facing each other (that is, the locking member 50 is rotated to the locked position) to meet the pressure bearing requirement during the cooking process.

[0125] Through the above steps, when closing the lid, the first hook 91 and the second hook 92 between the lid assembly and the pot body assembly are first engaged, and then the pot teeth and the lid teeth are aligned.

[0126] In the closed state:

[0127] The second hook 92 is kept in the fastened position under the action of the retainer; the lower locking member 140 is kept in the unlocked translation transmission member 120 position due to the downward pressure of the cover assembly, and the upper locking member 130 is kept in the unlocked transmission rocker 150 position due to the upward pressure of the pot assembly; the transmission rod 24 is located at Figure 17The rightmost end of the middle arc-shaped guide groove 146 , that is, the knob portion 21 is located at the right-hand limit position; the cover teeth and the pot teeth are kept in facing positions.

[0128] During the opening process:

[0129] The user first drives the cover teeth and pot teeth to dislocate by operating the knob 20, and then Figure 16 The knob portion 21 is rotated counterclockwise in the middle, and the transmission rod 24 moves counterclockwise along the arc-shaped guide groove 146. At this time, the transmission rod 24 and the Figure 16 The left side wall of the middle linkage section 1251 cooperates with the top to drive the translation transmission member 120 to Figure 16 The left side of the translation transmission member 120 moves, and the lower driving tooth 126 on the lower driven tooth 311 on the lower gear 31 is engaged, driving the lower gear 31, the lower coupling part 32, the coupling part 61 and the upper gear 63 to move synchronously along Figure 13 The upper driving tooth 631 of the upper gear 63 meshes with the upper driven tooth 1541 on the transmission rocker 150, driving the transmission rocker 150 to swing along the center of the rotating hole 152. Figure 14 During the swinging process of the transmission rocker 150, the locking member 50 is driven to rotate by the cooperation between the driving column 52 and the transmission hole 153 until the transmission rod 24 moves to Figure 16 The junction position of the middle linkage section 1251 and the avoidance section 1252 allows the locking member 50 to rotate from a position where the pot teeth and the cover teeth are directly opposite to a position where the pot teeth and the cover teeth are staggered.

[0130] The user continues along Figure 16 The knob portion 21 is rotated counterclockwise, and the transmission rod 24 enters the avoidance section 1252. Since the avoidance section 1252 avoids the trajectory of the transmission rod 24, the transmission rod 24 no longer drives the translation transmission member 120 to move during the rotation process. At this time, the locking rod 127 on the translation transmission member 120 is just moved to the top of the slot 145. The free end of the transmission rod 24 hits the push-up inclined surface 9232, and the transmission rod 24 continues to move along the Figure 16 The second hook 92 rotates in the counterclockwise direction and drives the second hook 92 to swing along the axis 922 as the center. Figure 16 Swing clockwise until the transmission rod 24 moves to Figure 14 The lowermost end of the left side of the middle arc guide groove 146 causes the second hook 92 to disengage from the first hook 91 on the cover assembly. At this time, the cover assembly automatically flips open under the action of the cover opening torsion spring set between the pot assembly and the cover assembly.

[0131] Through the above steps, when opening the lid, the pot teeth and the lid teeth between the lid assembly and the pot body assembly are firstly removed, and then the hook structure is released.
