Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a cover body assembly and a cooking appliance having the same. Background Art

[0002] A cooking appliance includes a pot body and a cover body assembly that can be opened and closed on the pot body. Due to the pressure during the cooking process, considering the safety of users, it is necessary to make the cover body assembly lockable on the pot body, so a caliper structure is provided on the cover body assembly. The caliper structure can move and has a locked position and an unlocked position. When the caliper structure is in the locked state, the cover body assembly and the pot body are locked to each other, and when the caliper structure is in the unlocked state, the cover body assembly and the pot body are separable.

[0003] The cover body assembly includes a face cover and a lining, and the caliper structure is installed on the lining. In order to prevent the lining from deforming during cooking and affecting the movement of the caliper structure, a metal fixing plate is provided on the lining, and the caliper structure is installed on the metal fixing plate.

[0004] In the related art, the metal fixing plate is positioned and fitted with the lining through a plurality of connecting columns (usually four). The plurality of connecting columns are distributed at the front and rear of the lining. The lining is provided with mounting holes for passing through the connecting columns, and the connecting columns are in clearance fit with the mounting holes. During cooking, the lining will deform due to heat, and the positions of the front and rear parts of the lining will move. When the clearance between the connecting column and the mounting hole is small, the metal fixing plate cannot move downward, so that the caliper structure is in frictional fit with the pot body, and the caliper structure cannot move, resulting in the cover body assembly not being able to be opened; when the clearance between the connecting column and the mounting hole is large, the caliper structure will shift, and the moving distance of the caliper structure is small and it cannot move to the unlocked state, resulting in the cover body assembly not being able to be opened. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a cover body assembly and a cooking appliance having the same, so as to solve the problem that the caliper structure in the related art cannot move or cannot move to the unlocked state, resulting in the cover body assembly not being able to be opened.

[0006] To achieve the above object, according to one aspect of the present utility model, a cover body assembly is provided, which is covered on a pot body. The cover body assembly includes: a cover body main body; a metal fixing plate, which is floatingly arranged below the cover body main body. At least two positioning structures are arranged between the metal fixing plate and the cover body main body, wherein the axes of at least two positioning structures are located in the same preset plane, and the preset plane extends along the transverse direction of the cover body main body and passes through the axis of the pot body; a locking mechanism, which is movably arranged on the metal fixing plate along the transverse direction of the cover body main body and has a locked state of locking the pot body and an unlocked state of unlocking the pot body.

[0007] Applying the technical solution of the present utility model, the metal fixing plate and the cover body main body are positioned and matched through at least two positioning structures. The axes of the above-mentioned at least two positioning structures are located in the same preset plane, and the preset plane extends along the transverse direction of the cover body main body and passes through the axis of the pot body. During the cooking process, the cover body main body will deform. Specifically, the center of the cover body main body bulges upward, and the front and rear ends of the cover body main body will slightly move toward the axis of the pot body. At this time, since the preset plane where the axes of the at least two positioning structures are located extends along the transverse direction of the cover body main body and passes through the axis of the pot body, that is, the positioning structures are located in the middle position of the cover body main body, the deformation of the cover body main body will not change the position of the positioning structures. Furthermore, it will not affect the positioning effect of the positioning structures. Since the above structure can ensure the positioning effect, the metal fixing plate can float smoothly, and the locking mechanism will not shift, so that the locking mechanism can move along a predetermined trajectory to lock or unlock the pot body. The technical solution of the present application can solve the problem in the related art that the caliper structure cannot move or cannot move to the unlocking state, resulting in the inability to open the cover assembly.

[0008] Furthermore, the positioning structure includes a positioning hole and a positioning post inserted into the positioning hole. One of the positioning hole and the positioning post is arranged on the cover body main body, and the other is arranged on the metal fixing plate. The above positioning hole and positioning post have simple structures, stable cooperation, are easy to process, and have low costs.

[0009] Furthermore, when the positioning hole is arranged on the cover body main body and the positioning post is arranged on the metal fixing plate, a sliding groove is arranged on the locking mechanism, and the sliding groove extends along the transverse direction of the cover body main body, and the positioning post is inserted into the sliding groove. In the above structure, the positioning post is arranged in the sliding groove, which can guide the locking mechanism so that the locking mechanism moves along a preset trajectory, making the locking and unlocking processes smoother.

[0010] Furthermore, the positioning post includes a first column body and a second column body detachably connected to the first column body. The first column body is arranged in the sliding groove, and the outer diameter of the second column body is larger than the groove width of the sliding groove. The above structure facilitates the assembly of the locking mechanism and the metal fixing plate. Moreover, after the two are assembled, the second column body can prevent the locking mechanism from detaching from the metal fixing plate.

[0011] Furthermore, the first column body and the second column body are threadedly connected. The above connection method is simple and convenient for assembly.

[0012] Furthermore, the second column body has a threaded inner hole, and the first column body has a threaded section, and the threaded section is connected in the threaded inner hole. The above structure is simple, easy to operate, easy to process, and has low costs.

[0013] Further, when the positioning hole is provided on the cover body main body and the positioning column is provided on the metal fixing plate, the positioning column protrudes upward from the positioning hole. The above structure enables the positioning column to always penetrate through the positioning hole when the metal fixing plate floats relative to the cover body main body, and the cooperation between the two is more stable.

[0014] Further, at least two positioning structures are symmetrically arranged with respect to the axis of the pot body. The above structure can effectively ensure the positioning effect.

[0015] Further, the locking mechanism includes a mounting plate and a caliper provided on the mounting plate; and / or, there are multiple locking mechanisms, and the multiple locking mechanisms are arranged on the metal fixing plate at intervals. The above locking mechanism has a simple structure and is easy to process; the multiple locking mechanisms can improve the locking effect.

[0016] According to another aspect of the present invention, a cooking appliance is provided, including a pot body and a cover body assembly covering the pot body, and the cover body assembly is the above-mentioned cover body assembly. Since the cover body assembly can solve the problem that the caliper structure in the related art cannot move or cannot move to the unlocked state, resulting in the cover body assembly being unable to be opened. Therefore, the cooking appliance having the above cover body assembly can also solve the above problem. Description of the Drawings

Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] Such as Figure 1As shown in the figure, the cover assembly of this embodiment covers the pot body 1, and the cover assembly includes: a cover body main body 10, a metal fixing plate 20, and a locking mechanism 30. In the above structure, the metal fixing plate 20 is floatingly arranged below the cover body main body 10, and at least two positioning structures are arranged between the metal fixing plate 20 and the cover body main body 10. Among them, the axes of at least two positioning structures are located in the same preset plane, and the preset plane extends along the transverse direction of the cover body main body 10 and passes through the axis of the pot body 1. The locking mechanism 30 is movably arranged on the metal fixing plate 20 along the transverse direction of the cover body main body 10 and has a locking state for locking the pot body 1 and an unlocking state for unlocking the pot body 1.

[0031] Applying the technical solution of this embodiment, the metal fixing plate 20 and the cover body main body 10 are positioned and matched through at least two positioning structures. The axes of the above at least two positioning structures are located in the same preset plane, and the preset plane extends along the transverse direction of the cover body main body 10 and passes through the axis of the pot body 1. The cover body main body 10 will deform during the cooking process. Specifically, the center of the cover body main body 10 bulges upward, and the front and rear ends of the cover body main body 10 will slightly move toward the axis of the pot body 1. At this time, since the preset plane where the axes of at least two positioning structures are located extends along the transverse direction of the cover body main body 10 and passes through the axis of the pot body 1, that is, the positioning structures are located in the middle position of the cover body main body 10, the deformation of the cover body main body 10 will not change the position of the positioning structures, and further, will not affect the positioning effect of the positioning structures. Since the above structure can ensure the positioning effect, the metal fixing plate 20 can float smoothly, and the locking mechanism 30 will not shift, so that the locking mechanism 30 can move along a predetermined trajectory to lock or unlock the pot body 1. The technical solution of this embodiment can solve the problem that the caliper structure in the related art cannot move or cannot move to the unlocking state, resulting in the cover assembly being unable to be opened.

[0032] As Figure 7 shown, the axis Z of the pot body 1 is a vertical axis. When the cross-section of the pot body is circular, the above axis Z passes through the center of the above circle. When the cross-section of the pot body is non-circular (such as an ellipse, a rectangle, etc.), the above axis passes through the center of the above non-circular shape. The above preset plane will form a straight line L in the top view direction of the cover assembly in Figure 6 which, and the straight line L extends along the transverse direction of the cover body main body 10 and intersects the axis Z of the pot body 1. The above transverse direction is also the left-right direction of the cover assembly.

[0033] As Figures 1 to 3 and Figure 6As shown, in this embodiment, the positioning structure includes a positioning hole 11 and a positioning post 21 inserted into the positioning hole 11. The positioning hole 11 is provided on the cover body main body 10, and the positioning post 21 is provided on the metal fixing plate 20. There is a clearance fit between the positioning hole 11 and the positioning post 21. The axes of the above-mentioned positioning post 21 and the positioning hole 11 are both located in a preset plane. In this way, when the center of the cover body main body 10 bulges upward, the positions of the positioning post 21 and the positioning hole 11 will not change, and thus a better positioning fit can still be achieved between the two. The above-mentioned positioning hole 11 and positioning post 21 have a simple structure, stable fit, are easy to process, and have a low cost.

[0034] Of course, in an embodiment not shown in the figure, the positioning hole can also be provided on the metal fixing plate. At this time, the positioning post is provided on the cover body main body. The above-mentioned embodiment can also achieve the positioning between the metal fixing plate and the cover body main body.

[0035] In this embodiment, as Figure 4 and Figure 5 shown, a sliding groove 31 is provided on the locking mechanism 30. The sliding groove 31 extends along the transverse direction of the cover body main body 10, and the positioning post 21 is inserted into the sliding groove 31. In the above structure, the positioning post 21 is provided in the sliding groove 31, which can guide the locking mechanism 30 so that the locking mechanism 30 moves along a preset trajectory, making the locking and unlocking processes smoother. The locking mechanism 30 moving along the preset trajectory also requires the cooperation of other mechanisms to achieve together. Specifically, a transmission post 34 is provided on the locking mechanism 30. The cover body assembly further includes an operating member, such as an opening handle or an opening button and other structures. The operating member can drive the transmission post 34 to move through a sliding plate, thereby controlling the locking mechanism 30 to move between the locked state and the unlocked state. A driving groove cooperating with the transmission post 34 is provided on the sliding plate. The cooperation between the driving groove and the transmission post and the cooperation between the positioning post and the sliding groove 31 together achieve the movement of the locking mechanism 30 along the preset trajectory. In this application, structures such as the operating member and the sliding plate are not shown in the figure. The specific structures and working processes of the operating member and the sliding plate can refer to CN117322757A.

[0036] As Figure 4 and Figure 5 shown, the cover body assembly further includes a mounting bracket 40. The mounting bracket 40 is connected to the metal fixing plate 20. The locking mechanism 30 is movably arranged in the mounting bracket 40. The mounting bracket 40 can limit the locking mechanism 30 in the up and down directions, so that the locking mechanism 30 can only move along the transverse direction of the cover body main body 10. A mounting post 41 is provided on the mounting bracket 40. The mounting post 41 can be connected to the cover body main body 10 by screws. Moreover, the metal fixing plate 20 is floatingly mounted below the cover body main body 10 through the mounting post 41 and screws, so that there is a gap between the caliper 33 and the flanging of the pot mouth of the pot body 1 in the up and down directions.

[0037] In this embodiment, as Figure 2 and Figure 3 shown, the positioning post 21 includes a first cylinder 211 and a second cylinder 212 detachably connected to the first cylinder 211. The first cylinder 211 is disposed in the chute 31, and the outer diameter of the second cylinder 212 is greater than the groove width of the chute 31. The above structure facilitates the assembly of the locking mechanism 30 and the metal fixing plate 20. Moreover, after the two are assembled, the second cylinder 212 can prevent the locking mechanism 30 from detaching from the metal fixing plate 20. Of course, as a feasible implementation manner, the positioning post can also be a cylinder structure with an equal diameter, and in this case, the locking mechanism can also be guided.

[0038] In this embodiment, the first cylinder 211 and the second cylinder 212 are threadedly connected. The above connection method is simple and convenient for assembly. Of course, the connection method between the first cylinder 211 and the second cylinder 212 is not limited to screw connection, and can also be welding, bonding and other methods.

[0039] More specifically, as Figure 2 shown, in this embodiment, the second cylinder 212 has a threaded inner hole, and the first cylinder 211 has a threaded section, and the threaded section is connected in the threaded inner hole. The above structure is simple, easy to operate, and easy to process, with a low cost.

[0040] As Figure 1 shown, the positioning post 21 protrudes upward from the positioning hole 11. After the metal fixing plate 20 and the cover body 10 are assembled, the distance that the positioning post 21 protrudes upward from the positioning hole 11 is H. H > 1 mm. The above structure enables the positioning post 21 to always pass through the positioning hole 11 when the metal fixing plate 20 floats relative to the cover body 10, and the cooperation between the two is more stable.

[0041] At least two positioning structures are symmetrically arranged with respect to the axis of the pot body 1. The above structure can effectively ensure the positioning effect. In this embodiment, the number of positioning structures is two. In other implementation manners, the number of positioning structures can also be four, six, etc.

[0042] As Figure 2 and Figure 4 shown, in this embodiment, the locking mechanism 30 includes a mounting plate 32 and a caliper 33 disposed on the mounting plate 32. The above locking mechanism 30 has a simple structure and is easy to process. In order to facilitate the cooperation with the caliper 33 to achieve locking or unlocking, a flanging structure is provided at the mouth of the pot body 1, and the caliper 33 can catch or avoid the above flanging structure.

[0043] In this embodiment, there are multiple locking mechanisms 30, and the multiple locking mechanisms 30 are arranged on the metal fixing plate 20 at intervals. The multiple locking mechanisms 30 can improve the locking effect. In this embodiment, there are two locking mechanisms 30, and each locking mechanism 30 includes two calipers 33. Of course, as a feasible implementation manner, the number of the locking mechanisms 30 can be four, and at this time each locking mechanism can include one caliper.

[0044] According to another aspect of the present utility model, there is provided a cooking appliance. The embodiment of the cooking appliance according to the present application includes a pot body 1 and a lid assembly covering the pot body 1, and the lid assembly is the above-mentioned lid assembly. Since the lid assembly can solve the problem that the caliper structure in the related art cannot move or cannot move to the unlocked state, and thus the lid assembly cannot be opened. Therefore, the cooking appliance having the above-mentioned lid assembly can also solve the above problem.

[0045] As Figure 7 shown, in this embodiment, the lid assembly further includes a face cover 50 and an inner cover 60. The face cover 50 covers the upper part of the lid body 10, the inner cover 60 is arranged below the metal fixing plate 20, and the inner cover 60 is detachably arranged to facilitate the user to clean it. A cooker body is further arranged on the outer side of the pot body 1, and the rear side of the lid body 10 is hinged to the cooker body.

[0046] The cooking appliance of the present application is a pressure cooker, and of course, it can also be an appliance with other functions such as a rice cooker, an electric slow cooker, a stir-fry machine, a food processor, etc.

[0047] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" 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 explanation, 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, so it cannot be understood as a limitation on 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.

[0048] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0049] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without further statement, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
