Description

Technical Field

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

[0002] Cooking appliances such as electric pressure cookers and rice cookers have been widely used in people's kitchens. The pot lids of such cooking appliances usually include an outer cover and an inner cover. In order to form a sealed cooking cavity between the inner cover and the pot body, a sealing ring is also provided on the inner side of the inner cover to seal the pot opening of the pot body.

[0003] In the related art, a positioning shaft is inserted through the mounting hole of the inner cover. A limiting groove is formed between the positioning shaft and the top wall of the inner cover. A latching portion that is snap-fitted with the limiting groove is provided on the outer edge of the sealing ring, so as to fix the sealing ring on the inner side of the inner cover.

[0004] However, during the process of assembling the inner cover and the positioning shaft together in the outer cover, since the positioning shaft and the mounting hole of the inner cover are in clearance fit, the positioning shaft is likely to move in the mounting hole of the inner cover, so that the positioning shaft is likely to fall off the inner cover. 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 that the positioning shaft in the related art is likely to fall off the inner cover.

[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 fixing portion is provided; an inner cover, including a top wall and a side wall surrounding the lower edge of the top wall, and a plurality of mounting holes are spacedly provided on the side wall; a positioning shaft, passing through two adjacent mounting holes, and a limiting groove is formed between the positioning shaft and the top wall; wherein, the inner cover is installed in the outer cover, and the first end of the positioning shaft is in abutting fit or interference fit with the fixing portion. When the first end of the positioning shaft is in abutting fit with the fixing portion, the positioning shaft is in abutting fit with the mounting hole.

[0007] By applying the technical solution of the utility model, the latching portion of the sealing ring of the cooking appliance extends into the limiting groove to limit the sealing ring within the inner cover. During the process of installing the positioning shaft and the inner cover together in the outer cover, since the first end of the positioning shaft is in abutting fit or interference fit with the fixing portion, the positioning shaft can remain stationary in the mounting hole, preventing the positioning shaft from falling off the inner cover, which is beneficial to improving the installation efficiency. Therefore, the technical solution of the present application effectively solves the problem that the positioning shaft in the related art is likely to fall off the inner cover.

[0008] Further, the fixing portion includes a blocking surface and a pressing surface. The blocking surface blocks the first end of the positioning shaft to prevent the positioning shaft from moving toward the blocking surface along its axis. When the first end of the positioning shaft is in abutting engagement with the fixing portion, the first end of the positioning shaft abuts against the pressing surface. The above structural arrangement enables the fixing portion to block the first end of the positioning shaft while also pressing the first end of the positioning shaft, so that the positioning shaft can remain stationary within the mounting hole.

[0009] Further, the fixing portion further includes a guiding surface connected to the pressing surface, and the first end of the positioning shaft is in guiding engagement with the guiding surface. The above guiding surface guides the first end of the positioning shaft, facilitating the first end of the positioning shaft to smoothly abut against the pressing surface.

[0010] Further, the pressing surface is located above the first end of the positioning shaft. In the above structure, in the direction of installing the inner cover into the outer cover, the pressing surface facilitates protecting the first end of the positioning shaft to prevent it from being accidentally touched and disengaging from the pressing surface.

[0011] Further, in order for the sealing ring to be reliably restricted within the inner cover, a limiting portion is further provided on the outer cover. The limiting portion is arranged at an interval from the fixing portion along the axial direction of the positioning shaft, and the second end of the positioning shaft is in limiting engagement with the limiting portion.

[0012] Further, the outer cover includes a face cover and a lining provided below the face cover, and the fixing portion is provided on the lining or the face cover. The above arrangement position of the fixing portion can be applied to the split outer cover structure, facilitating processing.

[0013] Further, the fixing portion is provided on the lining, and a limiting portion is provided on the face cover. The limiting portion is arranged at an interval from the fixing portion along the axial direction of the positioning shaft, and the second end of the positioning shaft is in limiting engagement with the limiting portion.

[0014] Further, in order to ensure that the sealing ring can be reliably restricted within the inner cover, a plurality of positioning shafts are circumferentially arranged at intervals along the side wall, and there are a plurality of fixing portions. The plurality of fixing portions correspond to the first ends of the plurality of positioning shafts one by one. The first end of each positioning shaft is in abutting engagement or interference fit with the corresponding fixing portion; and / or, the cover assembly further includes a sealing ring, and the outer edge of the sealing ring is provided with a protruding fastening portion, and the fastening portion is inserted into the limiting groove.

[0015] Further, the positioning shaft is a straight section extending along its axis. The above structural arrangement enables the positioning shaft to be processed without the need for further bending or flattening after cutting, simplifies the processing technology, and reduces the labor cost.

At the same time, it should be understood that for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. 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 need to be further discussed in subsequent drawings.

[0033] As Figures 1 to 5 shown, the present application provides a cover assembly. The embodiments of the cover assembly include: an outer cover 10, an inner cover 20, and a positioning shaft 30. A fixing portion 11 is provided on the outer cover 10. The inner cover 20 includes a top wall 21 and a side wall 22 surrounding the lower edge of the top wall 21. A plurality of mounting holes 221 are spaced apart on the side wall 22. The positioning shaft 30 passes through two adjacent mounting holes 221, and a limiting groove 23 is formed between the positioning shaft 30 and the top wall 21. Among them, the inner cover 20 is installed inside the outer cover 10, and the first end of the positioning shaft 30 is in abutting cooperation with the fixing portion 11. When the first end of the positioning shaft 30 is in abutting cooperation with the fixing portion 11, the positioning shaft 30 is in abutting cooperation with the mounting holes 221.

[0034] Applying the technical solution of this embodiment, the fastening portion of the sealing ring (not shown in the figure) of the cooking appliance extends into the limiting groove 23 to limit the sealing ring within the inner lid. During the process of installing the positioning shaft 30 and the inner lid 20 together within the outer lid 10, since the first end of the positioning shaft 30 abuts and cooperates with the fixing portion 11, the positioning shaft 30 can remain stationary within the mounting hole 221, preventing the positioning shaft from falling off the inner lid 20, which is beneficial to improving the installation efficiency. Therefore, the technical solution of this embodiment effectively solves the problem that the positioning shaft in the related art is prone to falling off the inner lid.

[0035] During the process of installing the positioning shaft 30 and the inner lid 20 together within the outer lid 10, since the positioning shaft 30 is located inside the outer lid 10, the outer lid 10 can block the line of sight of the installer. In this case, since the positioning shaft 30 can remain stationary within the mounting hole 221, it can be ensured that the positioning shaft 30 will not interfere with the structure on the outer lid 10 (such as the limiting portion described below), facilitating the smooth installation of the positioning shaft 30 and the inner lid 20 together within the outer lid 10.

[0036] In other embodiments, the first end of the positioning shaft 30 is in interference fit with the fixing portion 11. For example, the first end of the positioning shaft 30 is inserted into the fixing portion 11, specifically including a jack or a slot, and the first end of the positioning shaft 30 is directly inserted into the jack or the slot to be fixed on the fixing portion 11.

[0037] As Figures 3 to 7 shown, the fixing portion 11 includes a blocking surface 111 and a pressing surface 112. The blocking surface 111 blocks the first end of the positioning shaft 30 to prevent the positioning shaft 30 from moving along its axis towards the blocking surface 111. When the first end of the positioning shaft 30 abuts and cooperates with the fixing portion 11, the first end of the positioning shaft 30 abuts on the pressing surface 112. In this way, while the fixing portion 11 blocks the first end of the positioning shaft 30, it can also press the first end of the positioning shaft 30, facilitating the positioning shaft 30 to remain stationary within the mounting hole 221.

[0038] As Figures 3 to 7 shown, the fixing portion 11 further includes a guiding surface 113 connected to the pressing surface 112, and the first end of the positioning shaft 30 is in guiding cooperation with the guiding surface 113. In this way, after the first end of the positioning shaft 30 passes through two adjacent mounting holes 221 and contacts the guiding surface 113, the guiding surface 113 guides the first end of the positioning shaft 30, facilitating the first end of the positioning shaft 30 to smoothly abut on the pressing surface 112. The guiding surface 113 is preferably an upwardly inclined slope. The interference amount between the first end of the positioning shaft 30 and the pressing surface 112 is between 0.1 mm and 0.5 mm, that is, the deformation amount of the first end of the positioning shaft 30 is between 0.1 mm and 0.5 mm.

[0039] As Figures 3 to 7As shown, the pressing surface 112 is located above the first end of the positioning shaft 30. In the direction of installing the inner cover into the outer cover, the pressing surface 112 facilitates protecting the first end of the positioning shaft to prevent accidental contact and detachment from the pressing surface.

[0040] Of course, in an embodiment not shown in the figure, the pressing surface is located on the left or right side of the positioning shaft.

[0041] As Figures 3 to 8 shown, in order to reliably confine the sealing ring within the inner cover, a limiting portion 12 is further provided on the outer cover 10. The limiting portion 12 is spaced apart from the fixing portion 11 along the axial direction of the positioning shaft 30, and the second end of the positioning shaft 30 is in limiting cooperation with the limiting portion 12. In this way, the positioning shaft 30 is limited by the blocking surface 111 and the limiting portion 12 along its axial direction, and the positioning shaft 30 can be reliably held stationary within the mounting hole 221 to ensure that the formed limiting groove 23 can reliably confine the sealing ring.

[0042] In this embodiment, the limiting portion 12 includes a limiting plate or a limiting folding plate. The setting of the limiting folding plate is beneficial to improving the structural strength of the limiting portion 12.

[0043] As Figures 1 to 5 shown, the outer cover 10 includes a face cover 13 and a lining 14 provided below the face cover 13, and the fixing portion 11 is provided on the lining 14. In this way, the setting position of the fixing portion 11 can be applicable to the split structure of the outer cover 10, which is convenient for processing.

[0044] Of course, in an embodiment not shown in the figure, the fixing portion is provided on the lining.

[0045] As Figures 1 to 5 shown, the fixing portion 11 is provided on the lining 14, and the limiting portion 12 is provided on the face cover 13. The limiting portion 12 is spaced apart from the fixing portion 11 along the axial direction of the positioning shaft 30, and the second end of the positioning shaft 30 is in limiting cooperation with the limiting portion 12. The inner cover 20 can be first inserted into the lining 14, and then the positioning shaft 30 is laid flat to pass the positioning shaft 30 through two adjacent mounting holes 221. When the first end of the positioning shaft 30 is in abutting cooperation with the fixing portion 11, the positioning shaft 30 is in abutting cooperation with the mounting hole 221 so that the positioning shaft 30 remains stationary within the mounting hole 221. Finally, the face cover 13 is installed, and the second end of the positioning shaft 30 is limited by the limiting portion 12.

[0046] In this embodiment, a hollow portion is provided on the lining 14 for the limiting portion 12 to pass through from top to bottom.

[0047] As Figures 1 to 5As shown, in order to ensure that the sealing ring can be reliably restricted within the inner cover, a plurality of positioning shafts 30 are circumferentially spaced along the side wall 22, and there are a plurality of fixing portions 11. The plurality of fixing portions 11 correspond one by one to the first ends of the plurality of positioning shafts 30, and the first end of each positioning shaft 30 is in abutting fit or interference fit with the corresponding fixing portion 11.

[0048] In this embodiment, the number of the above-mentioned "plurality" is at least two.

[0049] The cover assembly further includes a sealing ring. An outwardly protruding fastening portion is provided on the outer edge of the sealing ring, and the fastening portion is inserted into the limiting groove 23. In this way, it is convenient to reliably restrict the sealing ring within the inner cover 20.

[0050] As Figures 1 to 5 shown, the positioning shaft 30 is a straight section extending along its axis direction. In this way, after the positioning shaft 30 is processed by cutting, there is no need for further bending or flattening treatment, which not only simplifies the processing technology and reduces the labor cost. Moreover, when the positioning shaft 30 passes through two adjacent mounting holes 221, the first end of the positioning shaft 30 can be inserted first, or the second end of the positioning shaft 30 can be inserted first, or it can be inserted from either of the left and right directions, which enriches the installation method of the positioning shaft 30, makes the installation more intuitive, convenient for assembly, and is beneficial to improving the installation efficiency. The positioning shaft 30 is preferably a steel needle.

[0051] This application also provides a cooking appliance, which includes a cover assembly, and the cover assembly is the above-mentioned cover assembly. Since the above-mentioned cover assembly can solve the problem that the positioning shaft in the related art is easily dropped from the inner cover, the cooking appliance including this cover assembly can solve the same technical problem.

[0052] The cooking appliance of this application is preferably an electric pressure cooker or an electric rice cooker.

[0053] 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, back, up, down, 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.

[0054] 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 the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0055] 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 additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0056] 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 modifications and changes. 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.
