[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil. Background Art

[0002] The pot body of the cooking utensil usually includes an outer cover, a middle ring located above the outer cover, and a base located below the outer cover. When assembled, the lower end of the outer cover is against the base, so that the base supports the outer cover. The middle ring is provided with a screw column extending downward, and the base is also provided with a screw column extending upward. The middle ring and the base are locked by screws so that the two clamp the outer cover from top to bottom.

[0003] However, in this assembly method, the base is only supported and positioned with the outer cover, and there is no positioning structure between the base and the middle ring, which makes it difficult to fix the base and the middle ring, and the assembly is difficult. Moreover, after the base and the outer cover are matched, the matching gap between the two is uneven, and at least one of the two is a plastic part, which will shrink after long-term use, resulting in a further increase in the assembly gap between the two, poor structural stability, and affecting the appearance quality and user experience.

[0004] In addition, the outer cover and the middle ring need to be fixed to the base respectively, which makes the assembly steps more complicated and the assembly efficiency is low. Utility Model Content

[0005] The utility model provides a cooking utensil to solve the problems that the existing pot body structure is complicated to assemble, the assembly steps are cumbersome, and when one of the base, the outer cover and the middle ring is deformed, the assembly gap will increase, affecting the appearance quality and the use experience.

[0006] The technical solution adopted by the utility model is:

[0007] A cooking utensil comprises a pot body, wherein the pot body comprises an outer cover, a middle ring arranged inside the outer cover, and a base located below the outer cover, wherein a plug-in groove is arranged on the circumference of the base, and the lower end of the middle ring cooperates with the lower end of the outer cover to form a plug-in portion, and the plug-in portion is plug-fitted with the plug-in groove so that the lower ends of the outer cover and the middle ring are fixed to the base together.

[0008] The cooking utensil of the present invention also has the following additional technical features:

[0009] The middle ring has a side wall, the lower end of the side wall is provided with a laterally extending support part, and the lower end of the outer cover is placed on the support part so that the two form a plug-in part.

[0010] The outer cover includes a body and a matching part located at the lower end of the body. The wall thickness of the matching part is smaller than that of the body to form a step surface on the lower end surface of the body. The matching part extends into the plug-in slot, and the step surface matches with the top stop of the plug-in slot wall.

[0011] The inner wall of the plug-in slot is provided with a recessed area for avoiding the supporting part.

[0012] At least one of the inserting portion and the slot wall of the inserting slot is provided with a guiding inclined surface to guide the inserting portion to be inserted into the inserting slot.

[0013] The plug-in slot has a first slot wall located inside and a second slot wall located outside. The guide slope includes a first slope arranged on the side of the middle ring facing the first slot wall and a second slope arranged on the side of the second slot wall facing the outer cover.

[0014] The edge of the base has a folded portion extending upward, and the base is also provided with a first reinforcing rib extending along the circumference of the base on the inner side of the folded portion, and an inserting groove is formed between the first reinforcing rib and the folded portion.

[0015] The base is provided with a plurality of second reinforcing ribs at intervals along its circumference, and the second reinforcing ribs are located on the inner side of the first reinforcing ribs and connected to the first reinforcing ribs.

[0016] The middle ring is provided with a first fixing portion extending downward, the base is provided with a second fixing portion extending upward, and the cooking utensil further comprises a fastener, which is used for fastening and connecting the first fixing portion and the second fixing portion.

[0017] The middle ring has a side wall extending from the upper end of the outer cover to the lower end of the outer cover.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, when assembling the pot body, firstly, the lower end of the middle ring and the lower end of the outer cover are matched to form a plug-in part, so that the middle ring and the outer cover form an integrated component, and then the middle ring and the outer cover are inserted into the plug-in slot of the base in an integrated manner. This allows the positioning and support between the middle ring, the outer cover and the base to be completed in one step. Compared with the method of positioning and installing the three separately, it can simplify the assembly steps, reduce the assembly difficulty and improve the assembly efficiency. In addition, the plug-in cooperation between the middle ring and the base can also play a role in pre-positioning the fixation of the middle ring, reducing the difficulty of fixing the middle ring and the base.

[0020] In addition, the base supports the lower ends of the outer cover and the middle ring at the same time, which can ensure that the fitting gap between the outer cover and the base is uniform and consistent. After the plastic parts are deformed and shrunk after long-term use, the base, outer cover and middle ring will deform synchronously, which can ensure that the assembly gap between the three remains unchanged, improve structural stability, ensure the appearance quality of the cooking utensils, and improve the user experience.

[0021] 2. As a preferred embodiment of the utility model, the middle ring has a side wall, and the lower end of the side wall is provided with a laterally extending support portion, and the lower end of the outer cover is placed on the support portion, so that the two constitute a plug-in portion. The support portion extends laterally at the lower end of the middle ring to have a supporting surface, and the lower end of the outer cover is placed on the supporting surface, so that the support portion supports the outer cover, and the two are simply fixed to form a plug-in portion together. Then the support portion is inserted as a whole into the plug-in slot to complete the plug-in positioning of the middle ring, the outer cover and the base, so that the base simultaneously supports the lower ends of the outer cover and the middle ring.

[0022] 3. As a preferred embodiment of the present invention, the outer cover includes a body and a matching part located at the lower end of the body, the wall thickness of the matching part is less than the wall thickness of the body, so as to form a step surface on the lower end surface of the body, the matching part extends into the plug-in slot, and the step surface cooperates with the top stopper of the plug-in slot wall. The wall thickness of the matching part is small, so that it can smoothly extend into the plug-in slot to complete the plug-in, while the wall thickness of the body is large, and a step surface is formed on the lower end surface. When the matching part is inserted into the plug-in slot, the step surface and the top stopper of the slot wall of the plug-in slot can not only serve as a reminder that the plug-in part and the plug-in slot are plugged in place, but also reduce the step difference and assembly gap between the outer surface of the outer cover and the outer surface of the base, so that the outer surface of the cooking utensil is smoother and more uniform, and the appearance quality and the operating feel are improved.

[0023] 4. As a preferred embodiment of the present invention, at least one of the plug-in portion and the slot wall of the plug-in slot is provided with a guiding slope to guide the plug-in portion to be inserted into the plug-in slot. The guiding slope can guide the plug-in fit between the plug-in portion and the plug-in slot, making the fit between the two smoother and avoiding jamming during assembly. In addition, the setting of the guiding slope can also compensate for certain processing errors, so that the plug-in portion and the plug-in slot can be plugged in normally, thereby improving the yield rate.

[0024] 5. As a preferred embodiment of the utility model, the middle ring has a side wall, and the side wall extends from the upper end of the outer cover to the lower end of the outer cover. The side wall of the middle ring extends from the upper part of the outer cover to the lower part of the outer cover, so that the side wall of the middle ring can form support for various areas of the outer cover in the circumferential direction inside the outer cover. When the outer cover tends to sag inward, the side wall of the middle ring can give the outer cover an outward support force to resist the inward deformation of the outer cover. Thereby, the deformation resistance of the outer cover is improved, so that the cooking utensil can maintain its appearance intact when it accidentally falls or collides, and the structural stability and the user experience are improved.

In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0043] like Figure 1 , Figures 3 to 6 As shown, a cooking utensil comprises a pot body, wherein the pot body comprises an outer cover 1, a middle ring 2 disposed inside the outer cover 1, and a base 3 disposed below the outer cover 1, a plug-in groove 32 is provided on the circumferential side of the base 3, the lower end of the middle ring 2 and the lower end of the outer cover 1 cooperate to form a plug-in portion, and the plug-in portion is plug-fitted with the plug-in groove 32, so that the lower ends of the outer cover 1 and the middle ring 2 are fixed to the base 3 together.

[0044] It should be noted that the "fixing" here should be understood in a broad sense, that is, the middle ring 2, the outer cover 1 and the base 3 can be fixedly connected and completely fixed by the cooperation of the plug-in portion and the plug-in slot 32. The three can also be simply fixed by the plug-in cooperation of the plug-in portion and the plug-in slot 32, that is, only a limit is formed at the plug-in position so that the three cannot move relative to each other at will, and then the three or two of them are fastened together by additional means such as screws to achieve complete fixation.

[0045] In the utility model, when assembling the pot body, the lower end of the middle ring 2 and the lower end of the outer cover 1 are first matched to form a plug-in portion, so that the middle ring 2 and the outer cover 1 form an integrated component, and then the middle ring 2 and the outer cover 1 are inserted into the plug-in slot 32 of the base 3 in an integrated manner. This allows the positioning and support between the middle ring 2, the outer cover 1 and the base 3 to be completed simultaneously in one step. Compared with the method of positioning and installing the three separately, it can simplify the assembly steps, reduce the assembly difficulty, and improve the assembly efficiency. In addition, the plug-in cooperation between the middle ring 2 and the base 3 can also play a pre-positioning role in the fixation of the middle ring 2, reducing the difficulty of fixing the middle ring 2 and the base 3.

[0046] In addition, the base 3 simultaneously supports the lower ends of the outer cover 1 and the middle ring 2, which can ensure that the fitting clearance between the outer cover 1 and the base 3 is uniform and consistent, and after the plastic parts are deformed and shrunk after long-term use, the base 3, the outer cover 1 and the middle ring 2 will deform synchronously, which can ensure that the assembly clearance between the three remains unchanged, improve the structural stability, ensure the appearance quality of the cooking utensil, and improve the user experience.

[0047] It should be noted that the present invention does not limit the materials of the outer cover 1, the middle ring 2 and the base 3. Preferably, the base 3 and the middle ring 2 are made of plastic materials to facilitate processing into different colors or shapes to improve the appearance quality. The outer cover 1 can be made of plastic or metal to give the cooking utensil a better texture.

[0048] In a preferred embodiment, Figure 2 , Figure 3 , Figure 4 As shown, the middle ring 2 has a side wall 21, and a laterally extending support portion 23 is disposed at the lower end of the side wall 21. The lower end of the outer cover 1 is placed on the support portion 23, so that the two form a plug-in portion.

[0049] The support portion 23 extends transversely at the lower end of the middle ring 2 to have a supporting surface, and the lower end of the outer cover 1 is placed on the supporting surface, so that the support portion 23 supports the outer cover 1, and the two are simply fixed to form a plug-in portion. Then the support portion 23 is inserted into the plug-in groove 32 as a whole to complete the plug-in positioning of the middle ring 2, the outer cover 1 and the base 3, so that the base 3 supports the lower ends of the outer cover 1 and the middle ring 2 at the same time.

[0050] Specifically, Figure 4 As shown, the side wall 21 of the middle ring 2 and the support portion 23 at the lower end cooperate to form an L-shaped support space, and the lower end of the outer cover 1 is placed in the support space.

[0051] In a preferred embodiment of this embodiment, Figures 3 to 6As shown, the outer cover 1 includes a main body 11 and a matching portion 12 located at the lower end of the main body 11. The wall thickness of the matching portion 12 is smaller than the wall thickness of the main body 11, so as to form a step surface 111 on the lower end surface of the main body 11. The matching portion 12 extends into the plug-in slot 32, and the step surface 111 cooperates with the top stop of the slot wall of the plug-in slot 32.

[0052] The wall thickness of the mating portion 12 is relatively small, so that it can be smoothly inserted into the plug-in slot 32 to complete the plug-in, while the wall thickness of the main body 11 is relatively large, and a step surface 111 is formed on the lower end surface. When the mating portion 12 is inserted into the plug-in slot 32, the step surface 111 and the top stop of the slot wall of the plug-in slot 32 can not only serve as a reminder that the plug-in portion and the plug-in slot 32 are plugged into place, but also can reduce the step difference and assembly gap between the outer surface of the outer cover 1 and the outer surface of the base 3, so that the outer surface of the cooking utensil is smoother and more uniform, and the appearance quality and operating feel are improved.

[0053] It should be noted that, when the lower end of the outer cover 1 is plugged into the base 3, the outer surface of the outer cover 1 can protrude from the outer surface of the base 3, forming an assembly step at the joint of the two. The outer surface of the outer cover 1 can also be flush with the outer surface of the base 3, making the outer surface of the cooking utensil smoother.

[0054] Furthermore, if Figure 6 As shown, the inner wall of the insertion slot 32 is provided with a recessed area 321 for avoiding the support portion 23 .

[0055] Since the support portion 23 extends laterally, the overall width of the plug-in portion is increased, and the recessed area 321 can avoid the support portion 23, so that the partial area in the plug-in slot 32 can match the width of the plug-in portion, thereby being able to normally accommodate the plug-in portion, so that the plug-in portion can be smoothly inserted into the plug-in slot 32. At the same time, it can also reduce the wear and tear of the plug-in portion and the plug-in slot 32 during the plug-in process, reduce the jamming feeling during the assembly process, and improve the assembly feel.

[0056] In another embodiment of the present embodiment, a reinforcing curling edge is provided at the lower end of the outer cover 1, and the reinforcing curling edge is placed on the support portion 23 at the lower end of the middle ring 2, and together with the support portion 23, constitutes a plug-in portion. The curling edge structure can improve the structural strength of the lower end of the outer cover 1, especially for the outer cover 1 made of metal material, the setting of the reinforcing curling edge can effectively prevent the outer cover 1 from being deformed during plug-in matching and use, thereby ensuring the structural stability of the outer cover 1.

[0057] As a preferred embodiment of the present invention, at least one of the plug-in portion and the slot wall of the plug-in slot 32 is provided with a guiding inclined surface to guide the plug-in portion to be inserted into the plug-in slot 32 .

[0058] The guide bevel can guide the plug-in fit between the plug-in portion and the plug-in slot 32, making the fit between the two smoother and avoiding jamming during assembly. In addition, the setting of the guide bevel can also compensate for certain processing errors, so that the plug-in portion and the plug-in slot 32 can be plugged in normally, thereby improving the yield rate.

[0059] Preferably, if Figure 6 As shown, the insertion slot 32 has a first slot wall 322 located on the inner side and a second slot wall 323 located on the outer side, and the guide slope includes a first slope 24 arranged on the side of the middle ring 2 facing the first slot wall 322, and a second slope 324 arranged on the side of the second slot wall 323 facing the outer cover 1.

[0060] like Figure 6 As shown, the middle ring 2 is located inside the outer cover 1, so when the plug-in portion formed by the two extends into the plug-in slot 32, the middle ring 2 is located on the side close to the first slot wall 322, and the outer cover 1 is located on the side close to the second slot wall 323. Since the thickness of the lower end of the middle ring 2 is relatively large, a first inclined surface 24 is provided on one side of the middle ring 2, and during the plug-in process, it cooperates with the first slot wall 322 to form a guide. However, the wall thickness of the lower end of the outer cover 1 is relatively thin, the strength is relatively low, and it is not easy to process the inclined surface structure, so a second inclined surface 324 is provided on the second slot wall 323 of the plug-in slot 32, and during the plug-in process, it cooperates with the outer cover 1 or the middle ring 2 to form a guide. In this way, one of the two inclined surfaces is provided on the plug-in portion, and the other is provided on the slot wall of the plug-in slot 32. While both sides of the plug-in slot 32 can be guided, the processing difficulty is reduced, and the overall strength of the plug-in structure is ensured.

[0061] Of course, guiding inclined surfaces may also be provided on both sides of the plug-in portion, and / or guiding inclined surfaces may be provided on the groove walls on both sides of the plug-in groove 32, which is not limited here.

[0062] As a preferred embodiment of the present invention, Figure 6 , Figure 7 As shown, the edge of the base 3 has a folded portion 35 extending upward, and the base 3 is further provided with a first reinforcing rib 34 extending circumferentially of the base 3 on the inner side of the folded portion 35 , and an insertion groove 32 is formed between the first reinforcing rib 34 and the folded portion 35 .

[0063] After the plug-in portion is inserted into the plug-in slot 32, the outer side is stopped by the folded portion 35, and the inner side is stopped by the first reinforcing rib 34, so that it is restricted in the plug-in slot 32, improving the stability of the cooperation between the two and ensuring that the assembly is not loose. In the subsequent use process, the base 3, the outer cover 1, and the middle ring 2 will shrink synchronously, which can ensure that the relative position between the three is stable, the assembly gap remains unchanged, and it is stable and reliable. At the same time, the first reinforcing rib 34 also plays a role in strengthening the structure of the peripheral edge of the base 3, which has multiple uses, simplifies the structure, and saves costs.

[0064] Furthermore, if Figure 7 As shown, the base 3 is provided with a plurality of second reinforcing ribs 33 at intervals along its circumference. The second reinforcing ribs 33 are located inside the first reinforcing ribs 34 and connected to the first reinforcing ribs 34 .

[0065] Each adjacent second reinforcing rib 33 on the base 3 is connected by the first reinforcing rib 34, so as to avoid contact between the plug-in portion and the end face of a single second reinforcing rib 33. Instead of limiting the plug-in portion with small ribs, the entire circumference of the side surface of the first reinforcing rib 34 limits the plug-in portion, which greatly increases the strength and reduces the risk of breakage and damage of a single second reinforcing rib 33 in the event of a collision.

[0066] It should be noted that the present invention does not limit the connection method between the base 3 and the middle ring 2, and the fixing direction of the outer cover 1. In a preferred embodiment, Figure 3 , Figure 5 As shown, the middle ring 2 is provided with a first fixing portion 22 extending downward, the base 3 is provided with a second fixing portion 31 extending upward, and the cooking utensil further comprises a fastener for fastening and connecting the first fixing portion 22 and the second fixing portion 31 .

[0067] During assembly, first, the plug-in part and the plug-in groove 32 are plugged together to achieve positioning and simple fixation of the middle ring 2 and the base 3, and then the first fixing part 22 and the second fixing part 31 are fastened and connected by fasteners such as screws to achieve complete fixation of the base 3 and the middle ring 2.

[0068] Furthermore, a part of the middle ring 2 is located above the outer cover 1 . After the middle ring 2 and the base 3 are fastened, under the tension of the fasteners, the outer cover 1 is clamped from the upper and lower sides to fix the outer cover 1 .

[0069] Preferably, if Figure 2 , Figure 3 As shown, the middle ring 2 has a side wall 21 , and the side wall 21 extends from the upper end of the outer cover 1 to the lower end of the outer cover 1 .

[0070] The side wall 21 of the middle ring 2 extends from the upper part of the outer cover 1 to the lower part of the outer cover 1, so that the side wall 21 of the middle ring 2 can form support for various areas of the outer cover 1 in the circumferential direction inside the outer cover 1. When the outer cover 1 tends to be concave inward, the side wall 21 of the middle ring 2 can give the outer cover 1 an outward support force to resist the inward deformation of the outer cover 1. Thereby, the deformation resistance of the outer cover 1 is improved, so that the cooking utensil can maintain its appearance intact when it is accidentally dropped or collided, and the structural stability and the use experience are improved.

[0071] like Figure 1 , Figure 2As shown, a decorative piece 4 is further arranged above the middle ring 2, and the decorative piece 4 constitutes the upper surface of the pot body to shield the top surface of the middle ring 2 and improve the appearance.

[0072] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0073] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0074] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
