Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and more specifically, to a cover assembly and a cooking appliance. Background Technique

[0002] In many cooking appliance products in the related art, the cover assembly of the cooking appliance includes a multi-layer structure, specifically including an outer cover and an inner cover arranged in sequence from top to bottom. The inner cover can rotate relative to the outer cover, and the inner cover is provided with cover teeth that cooperate with the pot teeth of the pot body of the cooking appliance.

[0003] The opening and closing processes of the above cooking appliance are realized by rotating the inner cover through a transmission member. The outer cover of this cooking appliance product is fixed. The transmission member rotates by a certain angle. Specifically, a guiding through hole is arranged on the outer cover, a driving long hole communicating with the guiding through hole is arranged on the transmission member, and a driving column penetrating into the guiding through hole and the driving long hole is arranged on the inner cover. When the transmission member rotates, the driving long hole on the transmission member pushes the driving column to rotate, so that under the guiding action of the guiding through hole, the inner cover rotates.

[0004] However, due to the gap between the driving column in the guiding through hole and the driving long hole, the driving column is prone to shaking, and there is a jamming situation when the transmission member drives the driving column to rotate, making the rotation of the inner cover not smooth. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a cover assembly and a cooking appliance to solve the problem of the unsmooth rotation of the inner cover in the related art.

[0006] To achieve the above purpose, according to one aspect of the utility model, a cover assembly is provided, including: an outer cover, on which a first guiding groove and a guiding through hole arranged in the first guiding groove are provided; a transmission member, movably arranged on the outer cover, and having a driving long hole on the transmission member; an inner cover, rotatably arranged inside the outer cover, and having a driving column penetrating into the guiding through hole and the driving long hole on the inner cover, the driving column is in guiding cooperation with the guiding through hole, and the transmission member drives the inner cover to rotate through the driving column; a guiding member, connected to the transmission member and in guiding cooperation with the first guiding groove.

[0007] By applying the technical solution of the utility model, when the transmission member moves, during the process that the transmission member drives the inner cover to rotate through the driving column, the guiding through hole guides the driving column, and the first guiding groove guides the guiding member, so that the transmission member moves smoothly, avoiding the jamming situation when driving the driving column to rotate, enabling the driving column to drive the inner cover to rotate smoothly, and solving the problem of the unsmooth rotation of the inner cover in the related art.

[0008] Furthermore, the guiding member is slidably disposed in the first guiding groove and shields the guiding through-hole. During the guiding process of the guiding member in the first guiding groove, since the guiding member shields the guiding through-hole, the leakage area of the guiding through-hole can be reduced, preventing the user from seeing the guiding through-hole and the structure between the outer cover and the inner cover through the guiding through-hole, avoiding light transmission and making the surface of the outer cover neater, and having a good appearance.

[0009] Furthermore, the guiding member includes a guiding piece that is guidingly engaged with the first guiding groove and a follower disposed on the guiding piece, and the follower is inserted into the driving long hole. When the driving long hole drives the driving column to rotate, the follower abuts against the hole wall of the driving long hole and slides relative to the hole wall of the driving long hole to drive the guiding piece to slide on the first guiding groove, facilitating the guiding function of the guiding member and the first guiding groove.

[0010] Furthermore, a through-hole for the driving column to pass through is provided on the guiding piece, and the through-hole corresponds to the guiding through-hole. The follower includes a first protrusion and a second protrusion located on both sides of the through-hole. The first protrusion abuts against the first hole wall surface of the driving long hole, and the second protrusion abuts against the second hole wall surface of the driving long hole. Since the first protrusion and the driving column abut against the first hole wall surface, and the second protrusion and the driving column abut against the second hole wall surface, the driving column is restricted in the guiding through-hole, the driving long hole, and the through-hole, and the driving column rotates in the guiding through-hole, the driving long hole, and the through-hole, reducing the possibility of the driving column shaking.

[0011] Furthermore, the first protrusion and / or the second protrusion includes a convex column. The setting of the convex column is convenient for processing on the one hand, and on the other hand, it is convenient for smooth contact with the first hole wall surface and the second hole wall surface, facilitating the sliding of the first protrusion and the second protrusion in the driving long hole.

[0012] Furthermore, to meet the requirement of the rotation range of the inner cover, the transmission member is swingably disposed on the outer cover, and in the swinging direction of the transmission member, the size of the first guiding groove is larger than the size of the guiding through-hole.

[0013] Furthermore, the guiding member shields the guiding through-hole, the transmission member is swingably disposed on the outer cover, and in the swinging direction of the transmission member, the ratio of the size of the guiding member to the size of the guiding through-hole is between 1.2 and 1.8. In the above structure, when the requirement of the above ratio range is met, no matter which position the guiding member rotates to, the guiding through-hole will be shielded by the guiding member, and the leakage area of the guiding through-hole can be reduced in real time, effectively preventing the user from seeing the guiding through-hole.

[0014] Further, a guiding structure is provided between the outer cover and the inner cover. The guiding structure includes a second guiding groove and a guiding post that is in guiding cooperation with the second guiding groove. One of the second guiding groove and the guiding post is provided on the outer cover, and the other is provided on the inner cover. In the above structure, during the rotation of the inner cover inside the outer cover, the guiding post rotates along the guiding direction of the second guiding groove, making the rotation of the inner cover inside the outer cover smoother and with less shaking.

[0015] Further, when pressing on the cooking appliance, in order to prevent the inner cover from floating up and interfering with the outer cover, in the vertical direction of the outer cover, there is a first distance between the bottom of the second guiding groove and the top of the guiding post, and a second distance between the top wall of the inner cover and the top wall of the outer cover. The first distance is greater than or equal to the second distance.

[0016] According to another aspect of the present invention, a cooking appliance is provided, including a cover assembly, and the cover assembly is the above-mentioned cover assembly. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0040] As Figure 1 、 Figures 5 to 8 shown, the present application provides a cover assembly. Embodiments of the cover assembly include: an outer cover 10, a transmission member 20, a handle 30, an inner cover 40, and a guide member 50. A first guide groove 11 and a guide through hole 12 provided in the first guide groove 11 are provided on the outer cover 10. The transmission member 20 is movably provided on the outer cover 10, and a driving long hole 21 is provided on the transmission member 20. The handle 30 is movably provided on the outer cover 10, and the handle 30 can drive the transmission member 20 to move. The inner cover 40 is rotatably provided inside the outer cover 10, and a driving column 41 penetrating through the guide through hole 12 and the driving long hole 21 is provided on the inner cover 40. The driving column 41 is in guiding cooperation with the guide through hole 12, and the transmission member 20 drives the inner cover 40 to rotate through the driving column 41. The guide member 50 is connected to the transmission member 20 and is in guiding cooperation with the first guide groove 11.

[0041] Applying the technical solution of this embodiment, when the handle 30 drives the transmission member 20 to move, during the process that the transmission member 20 drives the inner cover 40 to rotate through the driving column 41, the guide through hole 12 guides the driving column 41, and the first guide groove 11 guides the guide member 50, so that the transmission member 20 moves smoothly, avoiding the situation of jamming when driving the driving column 41 to rotate, so that the driving column 41 can drive the inner cover 40 to rotate smoothly, and solving the problem of the unsmooth rotation of the inner cover in the related art.

[0042] It should be noted that in this embodiment, the transmission member 20 is driven by the handle 30 to move. In other embodiments, the transmission member 20 is driven by a driving motor, and a trigger switch is provided on the cooking appliance for turning on or off the driving motor.

[0043] As Figures 5 to 10 shown, the guiding member 50 is slidably disposed in the first guiding groove 11 and covers the guiding through hole 12. In this way, under the guiding of the first guiding groove 11, the guiding member 50 slides smoothly and stably, so that the transmission member 20 connected to the guiding member 50 can also slide smoothly and stably. During this process, since the guiding member 50 covers the guiding through hole 12, the leakage area of the guiding through hole 12 can be reduced, preventing the user from seeing the guiding through hole 12 and the structure between the outer cover 10 and the inner cover 40 through the guiding through hole 12, avoiding light transmission and making the surface of the outer cover 10 more neat and having a good appearance.

[0044] As Figures 5 to 10 shown, the guiding member 50 includes a guiding piece 51 that is guidingly engaged with the first guiding groove 11 and a follower 53 disposed on the guiding piece 51, and the follower 53 is inserted into the driving long hole 21. The arrangement of the guiding piece 51 is convenient for processing, and is more conducive to guiding cooperation with the first guiding groove 11, and can cover the guiding through hole 12. At the same time, since the follower 53 is inserted into the driving long hole 21, when the driving long hole 21 drives the driving column 41 to rotate, the follower 53 abuts against the hole wall of the driving long hole 21 and slides relative to the hole wall of the driving long hole 21 to drive the guiding piece 51 to slide on the first guiding groove 11, facilitating the guiding member 50 to achieve a guiding effect with the first guiding groove 11.

[0045] In the present application, the inner cover is provided with cover teeth that cooperate with the pot teeth of the pot body of the cooking appliance. When the inner cover rotates, there is an unlocking position where the cover teeth are separated from the pot teeth and a locking position where the cover teeth are engaged with the pot teeth.

[0046] As Figures 5 to 10As shown, a through hole 52 for the driving column 41 to pass through is provided on the guiding piece 51, and the through hole 52 corresponds to the guiding through hole 12. In this way, the driving column 41 can be simultaneously inserted into the guiding through hole 12, the driving long hole 21 and the through hole 52, making the structure of the cover assembly compact. The follower 53 includes a first protrusion 531 and a second protrusion 532 located on both sides of the through hole 52. The first protrusion 531 abuts against the first hole wall surface 211 of the driving long hole 21, and the second protrusion 532 abuts against the second hole wall surface 212 of the driving long hole 21. In this way, during the process of the inner cover switching from the unlocked position to the locked position, the first hole wall surface 211 abuts against the first protrusion 531 and the driving column 41, and at the same time, both the first protrusion 531 and the driving column 41 slide in the driving long hole 21 along the first hole wall surface 211, so that the follower 53 drives the guiding piece 51 to slide, and the driving column 41 drives the inner cover 40 to rotate. During the process of the inner cover switching from the locked position to the unlocked position, the second hole wall surface 212 abuts against the second protrusion 532 and the driving column 41, and at the same time, both the second protrusion 532 and the driving column 41 slide in the driving long hole 21 along the second hole wall surface 212, so that the follower 53 drives the guiding piece 51 to slide, and the driving column 41 drives the inner cover 40 to rotate. Among them, since the first protrusion 531 and the driving column 41 abut against the first hole wall surface 211, and the second protrusion 532 and the driving column 41 abut against the second hole wall surface 212, the driving column 41 is restricted in the guiding through hole 12, the driving long hole 21 and the through hole 52, and the driving column 41 realizes rotation in the guiding through hole 12, the driving long hole 21 and the through hole 52, reducing the possibility of the driving column 41 shaking.

[0047] As Figure 9 and Figure 10 shown, the first protrusion 531 and the second protrusion 532 include convex columns. The setting of the convex columns is convenient for processing on the one hand, and on the other hand, it is convenient for smooth contact with the first hole wall surface 211 and the second hole wall surface 212, facilitating the sliding of the first protrusion 531 and the second protrusion 532 in the driving long hole 21.

[0048] In other embodiments, the first protrusion 531 or the second protrusion 532 includes a convex column.

[0049] As Figure 2 、 Figure 7 and Figure 8 shown, in order to meet the requirement of the rotation range of the inner cover, the transmission member 20 is swingably arranged on the outer cover 10, and in the swinging direction of the transmission member 20, the size of the first guiding groove 11 is larger than the size of the guiding through hole 12.

[0050] As Figure 2 、 Figure 7 and Figure 8As shown, the guiding member 50 shields the guiding through-hole 12. The transmission member 20 is swingably arranged on the outer cover 10. In the swinging direction of the transmission member 20, the ratio of the size of the guiding member 50 to the size of the guiding through-hole 12 is between 1.2 and 1.8. In this way, when the requirements of the above ratio range are met, no matter which position the guiding member 50 rotates to, the guiding through-hole 12 will be shielded by the guiding member 50, and the leakage area of the guiding through-hole 12 can be reduced in real time, effectively preventing users from seeing the guiding through-hole 12.

[0051] In this embodiment, the ratio of the size of the guiding member 50 to the size of the guiding through-hole 12 is preferably 1.2 or 1.4 or 1.5 or 1.6 or 1.8.

[0052] As Figures 1 to 4 、 Figure 11 and Figure 12 shown, a guiding structure is arranged between the outer cover 10 and the inner cover 40. The guiding structure includes a second guiding groove 13 and a guiding post 42 that is in guiding cooperation with the second guiding groove 13. The second guiding groove 13 is arranged on the outer cover 10, and the guiding post 42 is arranged on the inner cover 40. During the process of the inner cover 40 rotating inside the outer cover 10, the above-mentioned guiding post 42 rotates along the guiding direction of the second guiding groove 13, making the rotation of the inner cover 40 inside the outer cover 10 smoother and with less shaking. The structure of the above-mentioned guiding post 42 in guiding cooperation with the second guiding groove 13 is simple and easy to process and form. The diameter of the guiding post 42 is less than or equal to the groove width of the second guiding groove 13.

[0053] In other embodiments, the guiding post 42 is arranged on the outer cover 10, and the second guiding groove 13 is arranged on the inner cover 40.

[0054] As Figures 1 to 4 、 Figure 11 and Figure 12 shown, when pressing upwards inside the cooking appliance, in order to avoid interference between the inner cover 40 and the outer cover 10 when the inner cover 40 floats upwards, in the up and down direction of the outer cover 10, there is a first distance H1 between the bottom of the second guiding groove 13 and the top of the guiding post 42, and there is a second distance H2 between the top wall of the inner cover 40 and the top wall of the outer cover 10. The first distance H1 is greater than or equal to the second distance H2. In this way, when pressing upwards inside the cooking appliance, the guiding post 42 can continue to insert into the second guiding groove 13 towards the bottom of the second guiding groove 13, providing enough floating space for the inner cover 40 to float upwards and meeting the floating requirements of the inner cover 40.

[0055] In this embodiment, the outer cover 10 includes a lining 16 disposed outside the inner cover 40 and a face cover 17 disposed outside the lining 16. The handle 30 is movably disposed on the face cover 17, the transmission member 20 is movably disposed on the lining 16, and the first guide groove 11 and the guide through hole 12 are both disposed on the lining 16. In this embodiment, the guide through hole 12 is preferably an arc-shaped hole. Both the first guide groove 11 and the second guide groove 13 are arc-shaped grooves.

[0056] As Figures 1 to 4 shown, in this embodiment, the first sliding groove 14 and the second sliding groove 15 are spaced apart on the inner side wall of the outer cover 10, and the insertion block 43 and the locking block 44 are spaced apart on the outer side wall of the inner cover 40. The insertion block 43 can be slidably engaged with the first sliding groove 14, and the locking block 44 can be slidably engaged with the second sliding groove 15. When installing the inner cover 40, the inner cover 40 is inclined relative to the outer cover 10 to insert the insertion block 43 into the first sliding groove 14, and then the inner cover 40 is pushed, so that with the insertion block 43 as the swing point, the inner cover 40 swings in the direction close to the outer cover 10, so that the locking block 44 extends into the second sliding groove 15, thereby installing the inner cover 40 on the outer cover 10, and the inner cover 40 rotates relative to the outer cover 10 below the outer cover 10, and the groove wall of the first sliding groove 14 supports the insertion block 43, and the groove wall of the second sliding groove 15 supports the locking block 44. When the cooking appliance is pressed, the inner cover 40 is pushed to float relative to the outer cover 10. At this time, the insertion block 43 moves upward in the first sliding groove 14, and the locking block 44 moves upward in the second sliding groove 15. When disassembling the inner cover 40, the inner cover 40 is pulled, so that with the insertion block 43 as the swing point, the inner cover 40 swings in the direction away from the outer cover 10, so that the locking block 44 disengages from the second sliding groove 15, and the inner cover 40 is inclined relative to the outer cover 10 to facilitate removing the insertion block 43 from the first sliding groove 14.

[0057] The present application also provides a cooking appliance. The embodiment of the cooking appliance includes a lid assembly, and the lid assembly is the above-mentioned lid assembly. Since the above-mentioned lid assembly can solve the problem of unsmooth rotation of the inner cover in the related art, the cooking appliance including the lid assembly can solve the same technical problem.

[0058] In this embodiment, the pot body includes a heat preservation cover and an inner pot disposed in the heat preservation cover, and the pot teeth are disposed on the heat preservation cover.

[0059] The cooking appliance of this embodiment is a combined flip-type electric pressure cooker. The pot body further includes a housing disposed outside the heat preservation cover. A hinge structure is disposed between the housing and the lid assembly. A control circuit board is disposed in the housing, and electrical components such as pressure control and temperature measurement are disposed in the outer cover. The combined type setting of the combined flip-type electric pressure cooker facilitates the wired connection between the electrical components in the outer cover and the control circuit board in the housing, and ensures the reliability of the electrical connection.

[0060] Since a hinge structure is provided between the outer shell and the cover assembly, when the cover assembly is opened from the pot body, the whole cover assembly stands on the outer shell.

[0061] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0062] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations should be made for the spatial relative descriptions used here.

[0063] In addition, it should be noted that using words such as "first", "second", etc. to limit the components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it cannot be understood as a limitation to the protection scope of the present utility model.

[0064] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
