Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cooking equipment, and particularly relates to a stackable base for a cooking appliance and the cooking appliance. BACKGROUND

[0002] Common cooking appliances, such as electric rice cookers, are widely used by people due to their advantages of quickly cooking food and being able to process a variety of food materials. A cooking appliance generally comprises a heating part and a base below the heating part, and the base is an important component of the cooking appliance.

[0003] In the production and manufacturing process of the cooking appliance, the components are manufactured in a separate manner and then assembled. After the base is manufactured, it also needs to be stored in a warehouse to wait for subsequent assembly. In the storage of the base, the bases are usually stored in a manner that two bases are stacked one on top of the other and are oppositely buckled. The space utilization above each storage position is low, and the two bases are prone to relative sliding under the action of external force, which affects the stability of the base. In addition, the two bases are oppositely buckled and the outer surfaces of the bases are in contact with each other, which is prone to scratching the outer surfaces when the bases move relatively under the action of external force, affecting the appearance of the base. CONTENT OF THE UTILITY MODEL

[0004] The application provides a stackable base for a cooking appliance and the cooking appliance to solve the technical problems of low space utilization, instability of the base under the action of external force and scratching of the appearance of the base in the storage of the conventional base.

[0005] The technical scheme adopted by the application is as follows:

[0006] A stackable base for a cooking appliance comprises a limiting column which is hollow inside. The limiting column has an opening at the bottom, so that when a plurality of bases are stacked vertically, the limiting column of the upper base in the two adjacent bases can be nested in the limiting column of the lower base. In the two adjacent bases, the upper base is a first base, the limiting column thereon is a first limiting column, and the lower base is a second base, the limiting column thereon is a second limiting column.

[0007] The stackable base for a cooking appliance described in the application further comprises the following additional technical features:

[0008] A stop portion is arranged in the limiting column. The stop portion can be in stop cooperation with the second limiting column, so that when the second limiting column abuts against the stop portion, a first anti-abrasion gap is left between the upper surface of the second base and the first base.

[0009] The length of the first anti-abrasion gap is L1, and L1 is greater than or equal to 1 mm.

[0010] The limiting column comprises a first segment on the upper side and a second segment on the lower side, and the top end of the second segment is inwardly recessed to form the stop portion.

[0011] The first segment is open on the top and the inner wall is provided with mounting threads.

[0012] When the second limiting column abuts against the stop portion, a pulling gap is left between the outer wall of the second limiting column and the inner wall of the first limiting column.

[0013] The width of the pulling gap is D, and D≥0.5mm.

[0014] When the first limiting column is nested in the second limiting column, a second anti-abrasion gap is left between the first limiting column and the upper surface of the second base.

[0015] The length of the second anti-abrasion gap is L2, and L2≥1mm.

[0016] The application also provides a cooking utensil comprising a middle ring and a base, the base is the base as described above, the limiting column extends upward, the middle ring is provided with a corresponding downward extending screw column, and the limiting column and the screw column are connected by a screw.

[0017] Thanks to the above technical solutions, the application has the following advantages:

[0018] 1. The cooking utensil with stackable base provided with an internally hollow limiting column and an open bottom, so that when the base is stored, one base can be placed on the storage site first, and then the remaining bases are sequentially nested from bottom to top, and the relative fixation of the two adjacent bases is realized by the nested limiting columns, realizing the sequential stacking of multiple bases in the vertical direction, greatly improving the space utilization rate above the storage site, thereby improving the storage capacity of the base in the unit space; in addition, the limiting column can also limit the base horizontally, when the base is affected by external force or other factors and has a tendency to shift horizontally, the limiting column will limit the base and make it unable to shift, providing protection for the stability of the stacked base; furthermore, since the limiting columns of the bases are aligned with each other, when the two adjacent bases are stacked by nesting the limiting columns, the projections of the two bases in the vertical direction coincide, reducing the occupation of the base in the horizontal direction, further reducing the space occupation rate of the base storage.

[0019] 2. As a preferred embodiment of the application, by providing a stop portion in the limiting column, the second limiting column can abut against the stop portion to form a first anti-abrasion gap between the upper surface of the second base and the first base when the first base and the second base are stacked, preventing the first base from scratching the upper surface of the second base during stacking, and helping to maintain the integrity of the outer surface of the second base.

[0020] 3. As a preferred embodiment of the present application, the limiting column is provided with a first section and a second section, and the top of the second section is inwardly recessed to form a stop portion, which helps to optimize the structural design of the limiting column, and when the first limiting column is nested in the second limiting column, i.e. the gravity of the first base is applied to the second base, part of the gravity will be partially transmitted to the first section above the stop portion, reducing the bearing pressure of the stop portion and reducing the possibility of stress concentration phenomenon occurring at the stop portion.

[0021] 4. As a preferred embodiment of the present application, the top of the first section is open and provided with a mounting thread, which can be used to cooperate with the remaining components of the cooking utensil to serve as a fixing function, so that the limiting column further integrates the function of providing a mounting position for the upper component of the base in addition to the vertical stacking and horizontal limiting functions of the base, thereby eliminating the operation of opening the mounting structure on the base for mounting the upper component and optimizing the structural design of the base.

[0022] 5. As a preferred embodiment of the present application, a pulling gap is provided between the outer wall of the second limiting column and the inner wall of the first limiting column, which can prevent the first limiting column from being too tightly attached to the second limiting column, thereby improving the smoothness of the stacking and removal of the base and facilitating the handling of the base. On the other hand, the provision of the pulling gap provides a certain horizontal displacement space for the base. When the base is stacked, due to the influence of manual operation precision or other factors, there may be a certain alignment deviation between the first base above and the second base below. However, the provision of the pulling gap still allows the first limiting column to be nested in the second limiting column even if there is an alignment deviation between the first base and the second base, thereby reducing the probability of the first limiting column not being able to be nested in the second limiting column due to the alignment deviation between the first base and the second base, and improving the stacking efficiency of the base.

[0023] 6. As a preferred embodiment of the present application, a second wear-preventing gap is provided between the first limiting column and the upper surface of the second base. When the first base is stacked on the second base, the first limiting column will not come into contact with the upper surface of the second base due to the provision of the second wear-preventing gap, thereby avoiding scratching of the second base by the first limiting column and helping to maintain the integrity of the base.

[0024] 7. As a preferred embodiment of the present application, the number of limiting columns is multiple and arranged at intervals, which can improve the support stability of the second base to the first base and reduce the probability of the first base shaking under external force. In addition, the gravity of the first base is shared by multiple limiting columns, thereby reducing the possibility of stress concentration phenomenon occurring in the limiting column and helping to improve the service life of the limiting column.

[0042] As Figure 1 As shown in the figure, a stackable base 1 for cooking utensils includes an internally hollow limiting column 2, and the limiting column 2 has an opening at the bottom to enable the limiting column 2 of the upper base 1 among the adjacent two bases 1 to be nested in the limiting column 2 of the lower base 1 when the multiple bases 1 are stacked vertically; wherein, among the adjacent two bases 1, the upper base 1 is a first base 11, the limiting column 2 thereon is a first limiting column 21, and the lower base 1 is a second base 11, and the limiting column 2 thereon is a second limiting column 22.

[0043] It should be noted that the first base 11 and the second base 11 referred to herein refer to the relative relationship between two adjacent bases 1 in the vertical direction, for example, in a plurality of bases 1 stacked in the vertical direction, among the two bases 1 located at the bottom, the lowermost base 1 is the second base 11, and the second-to-last base 1 is the first base 11; and between the second-to-last base 1 and the third-to-last base 1, the second-to-last base 1 is the second base 11, and the third-to-last base 1 is the first base 11; the first limiting column 21 and the second limiting column 22 are the same.

[0044] The stackable base 1 of the cooking utensil of the present application is provided with a hollow limiting column 2, and the bottom of the limiting column 2 has an opening, so that when the base 1 is stored and placed, one base 1 can be placed on the storage position first, and then the remaining bases 1 are sequentially nested from bottom to top, and the relative fixation of the two adjacent bases 1 is realized by the nested limiting columns 2, realizing the sequential stacking of the plurality of bases 1 in the vertical direction, greatly improving the space utilization rate above the storage position, thereby improving the storage capacity of the base 1 in the unit space; in addition, the limiting column 2 can also play a horizontal limiting role for the base 1, when the base 1 is affected by external force or other factors and has a tendency to shift horizontally, the limiting column 2 will limit the base 1 so that it cannot be displaced, providing protection for the stability of the stacking of the base 1; furthermore, since the limiting columns 2 of the bases 1 are aligned with each other, when the two adjacent bases 1 are stacked by nesting the limiting columns 2, the projections of the two bases 1 in the vertical direction coincide, reducing the horizontal space occupied by the base 1, further reducing the space occupancy rate of the base 1 storage.

[0045] As a preferred embodiment of the present application, as shown in Figures 2 to 4 The limiting column 2 is provided with a stop portion 23, and the stop portion 23 can be stopped in cooperation with the second limiting column 22, so that when the second limiting column 22 abuts against the stop portion 23, the upper surface of the second base 11 and the first base 11 leave a first anti-abrasion gap 3.

[0046] By providing the stop portion 23 in the limiting column 2, the second limiting column 22 can be abutted to form a first anti-abrasion gap 3 between the upper surface of the second base 11 and the first base 11 when the first base 11 and the second base 11 are stacked, preventing the first base 11 from scratching the upper surface of the second base 11 during stacking, which helps to maintain the integrity of the outer surface of the second base 11.

[0047] As a preferred embodiment of the present embodiment, as shown in Figure 2As shown, the length of the first anti-abrasion gap 3 is L1, and L1≥1mm. Since there will inevitably be some machining errors in the base 1 during production, which may cause slight deviations in the size of the base 1, the length L1 of the first anti-abrasion gap 3 is set to L1≥1mm, which provides a reserved capacity for the errors in the machining of the base 1, reduces the possibility of the first base 11 being too thick or the upper surface of the second base 11 being uneven due to the machining errors of the base 1, and thus reduces the possibility of the first base 11 and the upper surface of the second base 11 being scratched.

[0048] The present embodiment does not limit the forming manner of the stop portion 23, which can adopt any one of the following embodiments:

[0049] Embodiment one: a transversely extending stop plate is arranged inside the limiting column 2, the stop plate abuts against the inner wall of the limiting column 2, and the stop plate constitutes the stop portion 23.

[0050] Embodiment two: as shown in Figure 3 , Figure 4 , the limiting column 2 includes a first segment 24 located above and a second segment 25 located below, and the top end of the second segment 25 is inwardly recessed to form the stop portion 23. Arranging the limiting column 2 to include the first segment 24 and the second segment 25, and arranging the top of the second segment 25 to be inwardly recessed to form the stop portion 23, helps to optimize the structural design of the limiting column 2, and when the first limiting column 21 is nested in the second limiting column 22, i.e., the gravity of the first base 11 is applied to the second base 11, part of the gravity will be partially transmitted to the first segment 24 above the stop portion 23, reducing the stress pressure of the stop portion 23 and reducing the possibility of stress concentration at the stop portion 23. In the present embodiment, the cross-sectional area of the first segment 24 is smaller than the cross-sectional area of the hollow cavity of the second segment 25, so that the first segment 24 can be inserted into the second segment 25.

[0051] Preferably, as shown in Figure 5 , the top of the first segment 24 is open and the inner wall is provided with a mounting thread 241. The open top of the first segment 24 and the mounting thread 241 can be used to cooperate with the remaining components of the cooking utensil to function as a fixing function, so that the limiting column 2 not only has the functions of vertical stacking and horizontal limiting of the base 1, but also integrates the function of providing a mounting position for the upper component of the base 1, thereby saving the operation of opening the mounting structure for mounting the upper component on the base 1 and optimizing the structural design of the base 1.

[0052] As another preferred embodiment of the present embodiment, as shown in Figure 4 , when the second limiting column 22 abuts against the stop portion 23, there is a pulling gap 5 between the outer wall of the second limiting column 22 and the inner wall of the first limiting column 21.

[0053] A pull-out gap 5 is provided between the outer wall of the second limiting post 22 and the inner wall of the first limiting post 21. On the one hand, this prevents the first limiting post 21 from being too tightly fitted with the second limiting post 22, which would cause difficulties in pulling out the base 1, thus improving the smoothness of stacking and removing the base 1 and making it easier to pick up the base 1. On the other hand, the pull-out gap 5 provides the base 1 with a certain horizontal displacement space. When stacking the base 1, due to the influence of manual operation precision or other factors, there may be a certain alignment deviation between the upper first base 11 and the lower second base 11. The pull-out gap 5 ensures that even if there is an alignment deviation between the first base 11 and the second base 11, the first limiting post 21 can still be nested into the second limiting post 22. This reduces the probability of the first limiting post 21 failing to be nested into the second limiting post 22 due to the alignment deviation between the first base 11 and the second base 11, thus helping to improve the stacking efficiency of the base 1.

[0054] Preferably, such as Figure 4 As shown, the width of the pull-out gap 5 is D, where D ≥ 0.5 mm. Since there will inevitably be some processing errors during the production of the limiting post 2, the dimensions of the limiting post 2 may have slight deviations. Setting the width D of the pull-out gap 5 to D ≥ 0.5 mm provides a reserve capacity for errors during the processing of the limiting post 2, preventing the second limiting post 22 from being too large to be inserted into the first limiting post 21 due to processing errors. This ensures the stacking of the base 1 and smooth pull-out.

[0055] As a preferred embodiment of this application, such as Figure 3 As shown, when the first limiting post 21 is nested within the second limiting post 22, a second anti-wear gap 4 is provided between the first limiting post 21 and the upper surface of the second base 11. With the second anti-wear gap 4 between the first limiting post 21 and the upper surface of the second base 11, when the first base 11 is stacked on top of the second base 11, due to the second anti-wear gap 4, the first limiting post 21 will not contact the upper surface of the second base 11, thereby preventing the first limiting post 21 from scratching the second base 11 and helping to maintain the integrity of the base 1.

[0056] Preferably, such as Figure 3 As shown, the length of the second anti-wear gap 4 is L2, and L2≥1mm. Since there will inevitably be certain processing errors in the production of the base 1 and the limiting post 2, there may be slight deviations in the size of the base 1 and the limiting post 2. Setting the length L2 of the second anti-wear gap 4 to L2≥1mm provides a reserve capacity for the errors in the processing of the base 1 and the limiting post 2, reducing the possibility of the second base 11 being too thick or the first limiting post 21 being too long due to processing errors, which would cause the first limiting post 21 to scratch the upper surface of the second base 11.

[0057] As a preferred embodiment of the present application, as shown in Figure 5 The number of the limiting posts 2 is multiple, and the multiple limiting posts 2 are arranged at intervals. The number of the limiting posts 2 is multiple and arranged at intervals, which can improve the support stability of the second base 11 to the first base 11, and reduce the probability of the first base 11 shaking under the action of external force. In addition, the gravity of the first base 11 is shared by the multiple limiting posts 2, which reduces the possibility of stress concentration phenomenon of the limiting posts 2, and helps to improve the service life of the limiting posts 2. Preferably, the number of the limiting posts 2 is greater than three.

[0058] A cooking utensil comprises a middle ring and a base, the base is the base as described in any of the above embodiments, the limiting posts extend upward, the middle ring is provided with corresponding downward extending screw posts, and the limiting posts and the screw posts are connected by screws. The base in the cooking utensil of the present application has screw posts and limiting posts, the screw posts play a role in connecting the base and the rest of the structure of the cooking utensil, and on this basis, it has the function of cooperating with the limiting posts to fix the mutually stacked bases, and the function integration is high.
