Description

Technical Field

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

[0002] At present, due to the characteristics of convenient and fast food processing, cooking appliances are widely used in people's daily lives.

[0003] In the related art, the cover assembly of a cooking appliance includes an outer cover and an inner cover with cover teeth. The inner cover is detachably installed below the outer cover, and the rotation of the inner cover is realized by arranging a sliding groove on the inner side wall of the outer cover. However, considering that the inner cover has a certain vertical floating space during the cooking process, the width of the sliding groove in the vertical direction needs to be increased, which causes the side of the inner cover close to the sliding groove to lose the positioning reference during the installation process of the inner cover on the outer cover, resulting in difficult installation of the inner cover. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a cover assembly and a cooking appliance having the same, so as to solve the problem that the side of the inner cover close to the sliding groove in the related art loses the positioning reference, resulting in difficult installation of the inner cover.

[0005] To achieve the above object, according to one aspect of the utility model, a cover assembly is provided, including: an outer cover and an inner cover. A first sliding groove is arranged on the inner side of the outer cover, and the first sliding groove includes a first section and a second section which are oppositely arranged in the circumferential direction. The inner cover is detachably installed on the outer cover and can rotate along the first sliding groove. Wherein, the widths of the first section and the second section in the vertical direction are different.

[0006] By applying the technical solution of the utility model, during the installation process of the inner cover on the outer cover, since the widths of the first section and the second section in the vertical direction are different, the smaller one of the widths of the first section and the second section can be used as a positioning reference to position the side of the inner cover close to the first sliding groove at the positioning reference, so that the inner cover can be smoothly installed on the outer cover, reducing the degree of difficulty in installing the inner cover. Therefore, the technical solution of the present application effectively solves the problem that the side of the inner cover close to the sliding groove in the related art loses the positioning reference, resulting in difficult installation of the inner cover.

[0007] Further, the width of the first section is smaller than that of the second section. An insertion block that can rotate in the first sliding groove is provided on the inner lid. When the inner lid is disassembled from and assembled onto the outer lid, the insertion block is limited within the first section. During the process of installing the inner lid onto the outer lid, the first section serves as a positioning reference, which can position the insertion block in the positioning reference, facilitating the smooth installation of the inner lid onto the outer lid. Moreover, when the insertion block rotates from the first section into the second section, since the width of the second section is greater than that of the first section, a space for the up-and-down floating of the inner lid during cooking is left, facilitating the up-and-down floating of the inner lid during cooking.

[0008] Further, in order to meet the requirements that the inner lid is easy to be disassembled from and assembled onto the outer lid on the one hand, and the inner lid can achieve up-and-down floating during cooking on the other hand, the width of the first section is a first dimension, the width of the second section is a second dimension, and the height of the insertion block in the vertical direction is a third dimension. The difference between the first dimension and the third dimension is in the range of 0.5 mm to 1 mm, and the difference between the second dimension and the third dimension is in the range of 2 mm to 6 mm.

[0009] Further, the first sliding groove includes a relatively arranged first upper side wall and a first lower side wall. The first lower side wall is closer to the mouth of the outer lid than the first upper side wall. The outer lid further includes a positioning member protruding from the first upper side wall. The gap between the positioning member and the first lower side wall in the vertical direction forms the first section. During the process of installing the inner lid onto the outer lid, the upward movement tendency of the side of the inner lid close to the first sliding groove relative to the outer lid is restricted by the positioning member, and the downward movement tendency of the side of the inner lid close to the first sliding groove relative to the outer lid is restricted by the first lower side wall, facilitating the reliable positioning of the side of the inner lid close to the first sliding groove within the first section.

[0010] Further, the first sliding groove further includes a bottom side wall connecting the first upper side wall and the first lower side wall. The positioning member is provided with a guiding surface, and the distance from the guiding surface to the bottom side wall gradually decreases in the vertical direction. During the process of installing the inner lid onto the outer lid, the guiding surface can guide the side of the inner lid close to the first sliding groove, facilitating the positioning of the side of the inner lid close to the first sliding groove at the positioning reference.

[0011] Further, the inner lid is rotatably installed below the outer lid to have an unlocking position and a locking position for cooperating with the pot body of the cooking appliance. When the inner lid is in the unlocking position, the first section is in positioning cooperation with the insertion block. When the inner lid is in the locking position, the first section is in avoidance cooperation with the insertion block, and there is a first floating gap between the insertion block and the upper side wall of the second section. Among them, in the circumferential direction of the inner lid, the size of the first sliding groove is greater than the size of the insertion block. The above structure enables the insertion block to rotate within the first sliding groove, facilitating the rotation of the inner lid below the outer lid and the switching of the inner lid between the unlocking position and the locking position. And setting the first floating gap can meet the requirement of the up-and-down floating of the inner lid under the upward pressure during cooking.

[0012] Further, in order to facilitate the detachable installation of the inner cover below the outer cover, a drop-preventing member is movably provided on the outer cover. The drop-preventing member has an avoidance position for installing the inner cover below the outer cover and a drop-preventing position for preventing the inner cover from falling from below the outer cover.

[0013] Further, a second chute is also provided on the inner side of the outer cover, and a clamping block capable of cooperating with the second chute is also provided on the inner cover. In the above structure, during the process of installing the inner cover below the outer cover, from the mouth of the outer cover from bottom to top, the insertion block is obliquely inserted into the first chute, and then the inner cover is righted and the clamping block is squeezed so that the clamping block slides into the second chute.

[0014] Further, the second chute includes a second upper side wall and a second lower side wall arranged oppositely. The second lower side wall is closer to the mouth of the outer cover than the second upper side wall. In the circumferential direction of the inner cover, the size of the second chute is larger than the size of the clamping block, and there is a second floating gap between the clamping block and the second upper side wall of the second chute. The above structure enables the clamping block to rotate in the second chute, facilitating the rotatability of the inner cover below the outer cover. And setting the second floating gap can meet the requirement that the inner cover floats up and down under the upward pressure during the cooking process.

[0015] According to another aspect of the present invention, a cooking appliance is provided, including a lid assembly, and the lid assembly is the above-mentioned lid assembly; the cooking appliance further includes a pot body, the pot body includes a heat preservation cover and an inner pot arranged in the heat preservation cover. There are pot teeth on the edge of the mouth of the heat preservation cover, and there are lid teeth on the lower edge of the inner cover. When the lid teeth are separated from the pot teeth, the inner cover is in the unlocked position, and when the lid teeth are engaged and cooperated with the pot teeth, the inner cover is in the locked position.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] It should be noted that the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. 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 in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed herein, 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.

[0034] As Figures 1 to 4 shown, the present application provides a cover assembly. Embodiment 1 of the cover assembly includes: an outer cover 10 and an inner cover 20. A first sliding groove 11 is provided on the inner side of the outer cover 10. The first sliding groove 11 includes a first section 101 and a second section 102 that are oppositely arranged in the circumferential direction. The inner cover 20 is detachably mounted on the outer cover 10 and can rotate along the first sliding groove 11. Among them, the widths of the first section 101 and the second section 102 in the vertical direction are different.

[0035] Applying the technical solution of Embodiment 1, since the widths of the first section 101 and the second section 102 in the vertical direction are different, the smaller one of the first section 101 and the second section 102 can be used as a positioning reference to position the side of the inner cover 20 close to the first sliding groove 11 at the positioning reference, so as to facilitate the smooth installation of the inner cover 20 on the outer cover 10 and reduce the degree of difficulty in installing the inner cover 20. Therefore, the technical solution of Embodiment 1 effectively solves the problem in the related art that the side of the inner cover close to the sliding groove loses the positioning reference, resulting in difficult installation of the inner cover.

[0036] As Figures 2 to 6As shown, the width of the first section 101 is smaller than that of the second section 102. An insertion block 21 that can rotate within the first sliding groove 11 is provided on the inner lid 20. When the inner lid 20 is disassembled from and assembled onto the outer lid 10, the insertion block 21 is limited within the first section 101. In this way, during the process of installing the inner lid onto the outer lid, the first section 101 serves as a positioning reference, enabling the insertion block 21 to be positioned within the positioning reference, facilitating the smooth installation of the inner lid onto the outer lid. Moreover, when the insertion block 21 rotates from the first section 101 into the second section 102, since the width of the second section 102 is greater than that of the first section 101, a space for the up-and-down floating of the inner lid during the cooking process is left, facilitating the up-and-down floating of the inner lid during the cooking process. The insertion block 21 is located on the side of the inner lid 20 close to the first sliding groove 11.

[0037] In the second embodiment of the lid assembly, the difference from the embodiment of the lid assembly lies in the structure of the first section 101 of the first sliding groove 11, as Figure 8 and Figure 9 shown. In the second embodiment, in order to satisfy, on the one hand, the easy disassembly and assembly of the inner lid from the outer lid 10, and on the other hand, the up-and-down floating of the inner lid during the cooking process, the width of the first section 101 is the first dimension L1, the width of the second section 102 is the second dimension L2, and the height of the insertion block 21 in the vertical direction is the third dimension L3. The difference between the first dimension L1 and the third dimension L3 is within the range of 0.5 mm to 1 mm, and the difference between the second dimension L2 and the third dimension L3 is within the range of 2 mm to 6 mm.

[0038] Specifically, the difference between the first dimension L1 and the third dimension L3 is 0.5 mm or 0.8 or 1 mm. The difference between the second dimension L2 and the third dimension L3 is 2 mm or 3 mm or 4 mm or 5 mm or 6 mm.

[0039] As Figures 2 to 6 shown, the first sliding groove 11 includes a first upper sidewall 111 and a first lower sidewall 112 that are oppositely arranged. The first lower sidewall 112 is closer to the mouth portion 15 of the outer lid 10 than the first upper sidewall 111. The outer lid 10 further includes a positioning member 30 protruding from the first upper sidewall 111. The gap between the positioning member 30 and the first lower sidewall 112 in the vertical direction forms the first section 101. During the process of installing the inner lid 20 onto the outer lid 10, the upward movement tendency of the side of the inner lid 20 close to the first sliding groove 11 relative to the outer lid 10 is restricted by the positioning member 30, and the downward movement tendency of the side of the inner lid 20 close to the first sliding groove 11 relative to the outer lid 10 is restricted by the first lower sidewall 112, facilitating the reliable positioning of the side of the inner lid 20 close to the first sliding groove 11 within the first section 101.

[0040] It should be noted that the positioning member 30 can be directly connected to one end of the first sliding groove 11 or can have a circumferential gap with one end of the first sliding groove 11.

[0041] Specifically, the positioning member 30 is a guiding rib, and the guiding rib is integrally formed at the connection between the first upper side wall 111 and the bottom side wall 113.

[0042] As Figures 2 to 6 shown, the first sliding groove 11 further includes a bottom side wall 113 connecting the first upper side wall 111 and the first lower side wall 112. A guiding surface 31 is provided on the positioning member 30, and the distance between the guiding surface 31 and the bottom side wall 113 gradually decreases in the vertical direction. During the process of installing the inner cover 20 on the outer cover 10, the guiding surface 31 can guide the side of the inner cover 20 close to the first sliding groove 11, facilitating the positioning of the side of the inner cover 20 close to the first sliding groove 11 at the positioning reference.

[0043] As Figures 4 to 8 shown, a second sliding groove 12 is further provided on the inner side of the outer cover 10, and a clamping block 22 capable of cooperating with the second sliding groove 12 is further provided on the inner cover 20. During the process of installing the inner cover 20 below the outer cover 10, from the mouth of the outer cover 10 from bottom to top, the insertion block 21 is obliquely inserted into the first sliding groove 11, and then the inner cover 20 is righted and the clamping block 22 is squeezed, facilitating the clamping block 22 to slide into the second sliding groove 12. In this way, the inner cover 20 is installed below the outer cover 10. And, the side wall of the second sliding groove 12 supports the clamping block 22.

[0044] As Figure 2 、 Figures 4 to 8 shown, the inner cover 20 is rotatably installed below the outer cover 10 to have an unlocking position and a locking position for cooperating with the pot body of the cooking appliance. When the inner cover 20 is in the unlocking position, the first section 101 is in positioning cooperation with the insertion block 21. When the inner cover 20 is in the locking position, the first section 101 is in avoidance cooperation with the insertion block 21, and there is a first floating gap H1 between the insertion block 21 and the upper side wall of the second section 102. Among them, in the circumferential direction of the inner cover 20, the size of the first sliding groove 11 is larger than the size of the insertion block 21. In this way, the insertion block 21 can rotate in the first sliding groove 11, facilitating the rotation of the inner cover 20 below the outer cover 10, and the inner cover 20 can be switched between the unlocking position and the locking position. When the positioning member 30 is in positioning cooperation with the insertion block 21, the insertion block 21 is limited between the positioning member 30 and the first lower side wall 112. When the positioning member 30 is in avoidance cooperation with the insertion block 21, after the upper pressure is applied to the pot body of the cooking appliance, the pressure in the pot body will push up the inner cover 20. At this time, due to the setting of the first floating gap H1, in this way, the insertion block 21 can move vertically in the first sliding groove 11 to meet the requirement that the inner cover 20 floats up and down under the upward pressure during the cooking process.

[0045] As Figure 2 、 Figures 4 to 8As shown in the figure, a second sliding groove 12 is further provided on the inner side of the outer cover 10, and a clamping block 22 capable of cooperating with the second sliding groove 12 is provided on the inner cover 20. The second sliding groove 12 includes a relatively arranged second upper side wall 121 and a second lower side wall 122. The second lower side wall 122 is closer to the mouth of the outer cover 10 than the second upper side wall 121. In the circumferential direction of the inner cover 20, the size of the second sliding groove 12 is larger than that of the clamping block 22. In this way, the clamping block 22 can rotate in the second sliding groove 12, facilitating the rotatability of the inner cover 20 under the outer cover 10. And there is a second floating gap H2 between the clamping block 22 and the second upper side wall 121 of the second sliding groove 12. After the pressure is applied to the inner wall of the pot body of the cooking appliance, the pressure in the pot body will push up the inner cover 20 upward. At this time, due to the provision of the second floating gap H2, the clamping block 22 can move vertically in the second sliding groove 12, meeting the requirement that the inner cover 20 floats up and down under the upward pressure during the cooking process.

[0046] As Figure 2 , Figures 4 to 8 shown in the figure, in order to facilitate the detachable installation of the inner cover 20 under the outer cover 10, a movable anti-drop member 40 is provided on the outer cover 10. The anti-drop member 40 has an avoidance position for installing the inner cover 20 under the outer cover 10 and an anti-drop position for preventing the inner cover 20 from falling off under the outer cover 10.

[0047] Specifically, a notch is communicated between the second lower side wall 122 and the lower edge of the outer cover 10. The anti-drop member 40 is movably arranged in the notch. The anti-drop member 40 is preferably an anti-drop hook. During the process of installing the inner cover 20 under the outer cover 10, the inner cover 20 is first placed obliquely at the mouth of the outer cover 10. When the anti-drop member 40 is in the avoidance position, the clamping block 22 enters the second sliding groove 12 from the notch. At this time, the position of the inner cover 20 is corrected to be horizontally placed. Then the anti-drop member 40 is in the anti-drop position, which can prevent the inner cover 20 from falling off under the outer cover 10.

[0048] In the first embodiment, the outer cover 10 includes a face cover 13 and a lining 14 provided on the inner side of the face cover 13. The inner cover 20 is detachably and rotatably arranged under the lining 14. During the process of installing the inner cover 20 of the first embodiment under the outer cover 10, the inner cover 20 is first placed under the mouth of the outer cover 10 and tilted from bottom to top, so that the insertion block 21 can be smoothly inserted into the first sliding groove 11 obliquely. Then, with the insertion block 21 as a reference, it swings from bottom to top to correct the inner cover 20, so that the clamping block 22 enters the second sliding groove 12 from the notch. At this time, the inner cover 20 is approximately horizontally installed under the outer cover 10, and the inner cover 20 can rotate under the outer cover 10.

[0049] The present application also provides a cooking appliance, which includes a lid assembly, and the lid assembly is the above-mentioned lid assembly. Since the above-mentioned lid assembly can solve the problem in the related art that the inner lid slides downward relative to the outer lid, resulting in difficult installation of the inner lid, the cooking appliance including this lid assembly can solve the same technical problem.

[0050] In this embodiment, the cooking appliance further includes a pot body, which includes a heat preservation cover and an inner pot disposed within the heat preservation cover. There are pot teeth provided on the edge of the mouth of the heat preservation cover, and there are lid teeth provided on the lower edge of the inner lid 20. When the lid teeth are separated from the pot teeth, the inner lid 20 is in the unlocked position, and when the lid teeth are engaged and cooperated with the pot teeth, the inner lid 20 is in the locked position.

[0051] The cooking appliance of this embodiment is a combined flip-up type electric pressure cooker. The pot body further includes a housing disposed outside the heat preservation cover. There is a hinge structure provided between the housing and the lid assembly. A control circuit board is disposed within the housing, and electrical components such as pressure control and temperature measurement are disposed within the outer lid. The combined type setting of the combined flip-up type electric pressure cooker facilitates the wired connection between the electrical components within the outer lid and the control circuit board within the housing, ensuring the reliability of the electrical connection.

[0052] Certainly, in other embodiments, the cooking appliance can also be products such as rice cookers, low-pressure rice cookers, soymilk makers, cooking machines, stir-fry machines, electric stew pots, multi-functional pots, etc.

[0053] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanations, these orientation words do not indicate and imply that the devices or elements 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 "inner, outer" 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.
