Description

Technical Field

[0001] The present invention relates to the field of household appliances, and more particularly to an upper cover assembly and a cooking utensil comprising the upper cover assembly. Background Art

[0002] In existing cooking appliances such as electric pressure cookers, the cover and the inner cover are usually assembled by fastening the front and rear buckles at the same time. Since the rear buckles on the cover and the inner cover are not elastic, disassembly and assembly are particularly laborious, which seriously affects the user experience. At the same time, the disassembly and assembly of the inelastic buckles will cause great wear and tear in daily use, which will soon cause the buckles to fail and not fasten tightly, greatly shortening the service life of the product. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] To this end, an object of one aspect of the present invention is to provide a top cover assembly.

[0005] A second aspect of the present invention is to provide a cooking utensil comprising the upper cover assembly.

[0006] To achieve the above-mentioned purpose, the technical solution of the first aspect of the present invention provides an upper cover assembly, comprising: an upper cover, on which a buckle plate is installed, and an elastic buckle position is formed on the buckle plate; and a cover plate, which is detachably installed on the upper cover, and on which a buckle that is adapted to the elastic buckle position is provided, and the elastic buckle position can be elastically deformed by the squeezing of the buckle when the cover plate is installed, and can be reset to fit tightly with the buckle under the action of the elastic force generated by the deformation after the cover plate is installed in place.

[0007] The upper cover assembly provided by the above technical scheme of the present invention has the following problems: when the cover is installed, the elastic buckle position on the buckle plate will be squeezed by the buckle on the cover plate to elastically deform, which is conducive to the smooth installation of the cover plate and makes the installation of the cover plate no longer laborious; after the cover is installed in place, the elastic buckle position will be reset under the elastic force generated by the deformation, and will be tightly matched with the buckle on the cover plate to ensure the firmness of the cover plate installed on the upper cover, thereby effectively solving the problem that the existing buckling structure causes the cover plate to be laborious to disassemble and assemble, and solves the problem that the buckle position in the existing structure is not fastened due to the large wear of the buckle position, and the problem that the buckle position has a large friction and powder falls into the food, affecting the health of the user; and the above-mentioned elastic buckle position relies on its own elastic force to deform and reset. Compared with the buckle position that has no elasticity and relies on additional elastic parts such as springs to achieve movement and reset, the above-mentioned scheme of the present invention does not need to set up additional elastic parts to assist the buckle position reset, and the buckle plate with elastic buckle position does not need to be moved as a whole, thereby reducing the number of parts of the entire upper cover assembly, simplifying the structure, simplifying assembly, and achieving high reliability.

[0008] Specifically, the above scheme of the present invention can solve two problems existing in the existing products in which the cover plate and the inner cover are fastened simultaneously by front and rear buckles. The first is the problem of laborious assembly and disassembly of the cover plate. When the cover plate is installed, the elastic buckle on the upper cover is squeezed by the buckle on the cover plate and elastically deformed, making it easier for the cover plate to be installed in the upper cover. At the same time, the buckle plate formed with the elastic buckle can be made of a material different from the inner cover of the upper cover, such as POM and other self-lubricating materials. When used, the friction generated when the buckle contacts the elastic buckle can be further reduced, thereby improving the user's experience when using it. Second, when the cover plate is disassembled and assembled, the old structure is that the buckle on the cover plate and the buckle on the inner cover are squeezed and rubbed hard, resulting in that the buckle on the cover plate and the buckle on the inner cover are easily invalidated due to wear and irreversible deformation, and finally cannot be hung tightly. In addition, the powder generated by the friction of assembly and disassembly may fall into the food, which will have an adverse effect on the health of the user. The above scheme of the present invention uses an elastic buckle structure, which can convert this extrusion and friction into a resettable deformation, thereby ensuring the service life of the product.

[0009] In addition, the upper cover assembly provided by the above technical solution of the present invention may also have the following additional technical features:

[0010] In the above technical solution, preferably, the buckle plate includes a buckle plate body, one end of the elastic buckle position is connected to the buckle plate body, and a hollow gap is formed between the other end of the elastic buckle position and the side of the elastic buckle position and the buckle plate body.

[0011] The elastic buckle formed by the above scheme can ensure that the elastic buckle has sufficient elasticity, so that the elastic buckle can produce elastic deformation with a large displacement when squeezed, thereby making the cover plate easier to install, and ensuring that the elastic buckle can be reset when the squeezing disappears, thereby ensuring the firmness of the cover plate and the upper cover. Preferably, the elastic buckle is integrally formed on the buckle plate body, for example, the above-mentioned elastic buckle is formed on the buckle plate body by punching, which not only ensures the connection strength between the elastic buckle and the buckle plate body, but also makes the processing of the elastic buckle convenient.

[0012] In the above technical solution, preferably, the other end of the elastic buckle position is tilted in a direction away from the buckle plate body, and the other end of the elastic buckle position is formed with a buckle hook protruding in the tilted side direction.

[0013] The elastic buckle is designed to have a structure with one end tilted up, so that the elastic buckle has a sufficiently large displacement when being squeezed by the buckle, thereby making it easier to install the cover.

[0014] In the above technical solution, preferably, a through hole is formed at one end of the elastic buckle position connected to the buckle plate body, and the through hole passes through the end surface of the one end of the elastic buckle position.

[0015] By providing a through hole on the elastic buckle, the connection area between the elastic buckle and the buckle plate body is reduced, which is beneficial to further improve the elasticity of the elastic buckle; preferably, the through hole is provided in the middle position of one end portion where the elastic buckle is connected to the buckle plate body, which is beneficial to ensure that the elastic buckle is subjected to balanced force; preferably, the through hole on the elastic buckle is a strip hole extending from one end portion where the elastic buckle is connected to the buckle plate body toward the other end portion of the elastic buckle.

[0016] In the above technical solution, preferably, the number of the elastic buckles is two, the two elastic buckles are arranged side by side on the buckle plate, and the cover plate is provided with the buckles corresponding to each of the elastic buckles.

[0017] By arranging two elastic buckles side by side on the buckle plate, the firmness of the assembly between the cover plate and the upper cover is improved.

[0018] In any of the above technical solutions, preferably, the upper cover includes an inner cover, the inner cover is provided with a buckle plate mounting groove, the buckle plate is inserted into the side wall of the buckle plate mounting groove, and the elastic buckle position protrudes toward the inner cavity of the buckle plate mounting groove.

[0019] The above design enables the buckles on the cover to squeeze the elastic buckles in the mounting groove of the buckle plate when the cover is assembled, and the elastic buckles are squeezed and deformed, thereby ensuring that the buckles on the cover are smoothly buckled with the elastic buckles of the buckle plate.

[0020] In the above technical solution, preferably, the upper cover also includes a sealing ring and a pressure plate, the sealing ring is installed on the outer end surface of the buckle plate and presses the buckle plate, the pressure plate is pressed onto the sealing ring, and the pressure plate, the sealing ring and the inner cover are fastened together by fasteners.

[0021] Specifically, during assembly, the buckle plate with elastic buckle positions is inserted into the buckle plate mounting groove of the inner cover, and then the sealing ring and the pressure plate are pressed onto the buckle plate in sequence, and then the pressure plate, the sealing ring and the inner cover are locked and fixed by fasteners such as screws, thereby achieving a firm assembly of the buckle plate on the inner cover; the sealing ring can ensure the sealing between the cover plate and the inner cover.

[0022] In any of the above technical solutions, preferably, the buckle plate is installed at the rear end position of the inner side of the upper cover, and a buckle hook is formed on the elastic buckle position, protruding toward the front end direction of the upper cover; the cover plate includes a cover plate body and a fixing seat installed on the cover plate body on the side facing the upper cover, and the upper outer surface of the fixing seat protrudes backward to form the buckle.

[0023] Of course, the above-mentioned gusset plate is not limited to being arranged at the rear end position of the inner side of the upper cover, and the above-mentioned gusset plate can also be arranged at the front end position of the inner side of the upper cover. The specific arrangement position of the gusset plate can be reasonably designed and adjusted according to the actual structure of the product.

[0024] In the above technical solution, preferably, an exhaust valve is provided on the cover plate, the fixing seat is an exhaust valve seat, and the exhaust valve is arranged on the exhaust valve seat.

[0025] The fixed seat is the exhaust valve seat, that is, the buckle is formed on the exhaust valve seat, that is, the buckle is arranged on the existing structural member of the upper cover assembly, and there is no need to increase the number of additional parts in order to realize the connection between the cover plate and the upper cover, so that the number of parts of the entire upper cover assembly is small, the structure is simpler, and the assembly is more convenient.

[0026] In the above technical solution, preferably, a first mating bevel is formed on the rear side of the buckle, and a second mating bevel is formed on the front side of the hook. When the cover is installed, the first mating bevel cooperates with the second mating bevel to squeeze the elastic buckle position backward, causing the elastic buckle position to deform elastically.

[0027] When the cover is installed, the first matching bevel on the buckle and the second matching bevel on the hook play a guiding role, making it easier for the buckle to pass over the hook smoothly and fit tightly with the hook; and when the cover is installed, the first matching bevel on the buckle cooperates with the second matching bevel on the hook of the elastic buckle position, which will squeeze the elastic buckle position backwards, causing the elastic buckle position to deform, making it easier to install the cover into the upper cover.

[0041] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0043] Please refer to the attached Figures 1 to 6 An upper cover assembly and a cooking appliance according to some embodiments of the present invention are described.

[0044] like Figures 1 to 6 As shown, a top cover assembly provided according to some embodiments of the present invention includes: a top cover 1 and a cover plate 2.

[0045] Specifically, a buckle plate 11 is installed on the upper cover 1, and an elastic buckle position 111 is formed on the buckle plate 11; the cover plate 2 is detachably installed on the upper cover 1, and a buckle 211 adapted to the elastic buckle position 111 is provided on the cover plate 2. The elastic buckle position 111 can be elastically deformed by the squeezing of the buckle 211 when the cover plate 2 is installed, and can be reset to fit tightly with the buckle 211 under the action of the elastic force generated by the deformation after the cover plate 2 is installed in place.

[0046] In the upper cover assembly provided by the above embodiment of the present invention, when the cover plate 2 is installed, the elastic buckle position 111 on the buckle plate 11 will be squeezed by the buckle 211 on the cover plate 2 and elastically deformed. Figure 3 The rightward arc arrow in the middle indicates the moving direction of the elastic buckle 111 when it is squeezed, which is conducive to the smooth installation of the cover plate 2 and makes the installation of the cover plate 2 less laborious; after the cover plate 2 is installed in place, the elastic buckle 111 will be reset under the elastic force generated by the deformation and tightly fit with the buckle 211 on the cover plate 2, such as Figure 3 The leftward arc arrow in the middle indicates the moving direction of the elastic buckle 111 when the extrusion disappears, ensuring the firmness of the cover plate 2 installed on the upper cover 1, thereby effectively solving the problem of the existing buckling structure causing the cover plate 2 to be laborious to disassemble and assemble, and solving the problem of the existing structure that the buckle is not fastened due to the large wear of the buckle, and the problem that the buckle friction is large and powder falls into the food and affects the health of the user; and the above-mentioned elastic buckle 111 relies on its own elastic force to deform and reset. Compared with the buckle that has no elasticity and relies on additional elastic parts such as springs to achieve movement and reset, the above-mentioned scheme of the present invention does not need to set up additional elastic parts to assist the buckle reset, and the buckle plate 11 with the elastic buckle 111 does not need to move as a whole, so that the number of parts of the entire upper cover assembly is small, the structure is simplified, the assembly is simple, and the reliability is high.

[0047] Specifically, the above-mentioned embodiment of the present invention can solve two problems existing in the existing products in which the cover plate 2 and the inner cover 12 are fastened simultaneously by the front and rear buckles. One is the problem of the difficulty in disassembling and assembling the cover plate 2. When the cover plate 2 is installed, the elastic buckle position 111 on the upper cover 1 is squeezed by the buckle 211 on the cover plate 2 and elastically deforms, making it easier for the cover plate 2 to be installed into the upper cover 1. At the same time, the buckle plate 11 formed with the elastic buckle position 111 can be made of a material different from that of the inner cover 12 of the upper cover 1, such as POM (i.e., polyoxymethylene thermoplastic crystalline polymer) and other self-lubricating materials, which can further reduce the buckle when used. The friction force generated when 211 contacts with the elastic buckle position 111 improves the user's experience when using it; secondly, when the cover plate 2 is disassembled and assembled, the old structure is that the buckle position on the cover plate 2 and the buckle position on the inner cover 12 are squeezed and rubbed against each other, which causes the buckle position of the cover plate 2 and the buckle position of the inner cover 12 to fail easily due to wear and irreversible deformation, and eventually cannot be hung tightly; and the powder generated by the friction of disassembly and assembly may fall into the food, which will have an adverse effect on the user's health. The above-mentioned scheme of the present invention uses the elastic buckle position 111 structure, which can convert this squeezing and friction into resettable deformation, thereby ensuring the service life of the product.

[0048] In one embodiment of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the buckle plate 11 includes a buckle plate body 112 , one end of the elastic buckle position 111 is connected to the buckle plate body 112 , and a hollow gap 113 is formed between the other end of the elastic buckle position 111 and the side of the elastic buckle position 111 and the buckle plate body 112 .

[0049] The elastic buckle 111 formed by the above scheme can ensure that the elastic buckle 111 has sufficient elasticity, so that the elastic buckle 111 can produce elastic deformation with a large displacement when squeezed, thereby making the cover 2 easier to install, and ensuring that the elastic buckle 111 can be reset when the squeezing disappears, thereby ensuring the firmness of the cover 2 and the upper cover 1; preferably, the elastic buckle 111 is integrally formed on the buckle plate body 112, for example, the above-mentioned elastic buckle 111 is formed on the buckle plate body 112 by punching, which not only ensures the connection strength between the elastic buckle 111 and the buckle plate body 112, but also makes the processing of the elastic buckle 111 convenient.

[0050] Furthermore, if Figures 2 to 4 As shown, a through hole 114 is formed at one end of the elastic buckle position 111 connected to the buckle plate body 112 , and the through hole 114 passes through the end surface of the end of the elastic buckle position 111 connected to the buckle plate body 112 .

[0051] By providing a through hole 114 on the elastic buckle position 111, the connection area between the elastic buckle position 111 and the buckle plate body 112 is reduced, which is beneficial to further improve the elasticity of the elastic buckle position 111; preferably, the through hole 114 is provided in the middle position of one end portion where the elastic buckle position 111 is connected to the buckle plate body 112, which is beneficial to ensure that the force on the elastic buckle position 111 is balanced; preferably, the through hole 114 is a strip hole extending from one end portion where the elastic buckle position 111 is connected to the buckle plate body 112 toward the other end portion of the elastic buckle position 111.

[0052] Preferably, if Figure 3 As shown, the other end of the elastic buckle position 111 is tilted away from the buckle plate body 112, and the other end of the elastic buckle position 111 is formed with a buckle hook 115 protruding toward the tilting side.

[0053] The elastic buckle position 111 is designed to have a structure with one end tilted up, so that the elastic buckle position 111 has a sufficiently large displacement when being squeezed by the buckle 211, thereby making it easier to install the cover plate 2.

[0054] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, there are two elastic buckle positions 111 , which are arranged side by side on the buckle plate 11 , and buckles 211 corresponding to each elastic buckle position 111 are provided on the cover plate 2 .

[0055] By arranging two elastic buckles 111 side by side on the buckle plate 11 , the firmness of the assembly between the cover plate 2 and the upper cover 1 is improved; in order to improve the structural strength of the buckle plate 11 , a reinforcing rib may be provided between the two elastic buckles 111 arranged side by side.

[0056] In some embodiments of the present invention, Figure 1 As shown, the upper cover 1 includes an inner cover 12, on which a buckle plate mounting groove 121 is provided, the buckle plate 11 is inserted into the side wall of the buckle plate mounting groove 121, and the elastic buckle position 111 protrudes toward the inner cavity of the buckle plate mounting groove 121. Specifically, one end of the elastic buckle position 111 connected to the buckle plate body 112 is inserted into the buckle plate mounting groove 121 as an insertion end.

[0057] The above design enables the buckle 211 on the cover plate 2 to squeeze the elastic buckle position 111 located in the buckle plate mounting groove 121 when the cover plate 2 is assembled, and the elastic buckle position 111 is squeezed and deformed, thereby ensuring that the buckle 211 on the cover plate 2 and the elastic buckle position 111 of the buckle plate 11 are smoothly buckled.

[0058] Furthermore, if Figure 1 and Figure 6As shown, the upper cover 1 also includes a sealing ring 13 and a pressure plate 14. The sealing ring 13 is installed on the outer end surface of the buckle plate 11 and presses the buckle plate 11. The pressure plate 14 is pressed onto the sealing ring 13. The pressure plate 14, the sealing ring 13 and the inner cover 12 are fastened together by fasteners.

[0059] Specifically, during assembly, the buckle plate 11 provided with the elastic buckle position 111 is inserted into the buckle plate mounting groove 121 of the inner cover 12, and specifically, the end of the elastic buckle position 111 connected to the buckle plate body 112 is inserted into the buckle plate mounting groove 121 as the insertion end, and then the sealing ring 13 and the pressure plate 14 are pressed onto the buckle plate 11 in sequence, and then the pressure plate 14, the sealing ring 13 and the inner cover 12 are locked and fixed by fasteners such as screws 15, so as to achieve a firm assembly of the buckle plate 11 on the inner cover 12; the sealing ring 13 can ensure the sealing between the cover plate 2 and the inner cover 12.

[0060] In some embodiments of the present invention, Figure 1 , Figure 5 and Figure 6 As shown, the buckle plate 11 is installed at the rear end position of the inner side of the upper cover 1, and a buckle hook 115 is formed on the elastic buckle position 111 and protrudes toward the front end direction of the upper cover 1; the cover 2 includes a cover body 22 and a fixing seat 21 installed on the side of the cover body 22 facing the upper cover 1, and the upper outer surface of the fixing seat 21 protrudes backward to form a buckle 211.

[0061] Of course, the above-mentioned buckle plate 11 is not limited to being arranged at the rear end position of the inner side of the upper cover 1, and the above-mentioned buckle plate 11 can also be arranged at the front end position of the inner side of the upper cover 1. The specific arrangement position of the buckle plate 11 can be reasonably designed and adjusted according to the actual structure of the product.

[0062] In a specific embodiment, Figure 6 As shown, the cover plate 2 is provided with an exhaust valve 23, the fixed seat 21 is an exhaust valve seat, and the exhaust valve 23 is arranged on the exhaust valve seat.

[0063] The fixing seat 21 is an exhaust valve seat, that is, the buckle 211 is formed on the exhaust valve seat, that is, the buckle 211 is arranged on the existing structural member of the upper cover assembly, and there is no need to increase the number of additional parts in order to realize the connection between the cover plate 2 and the upper cover 1, so that the number of parts of the entire upper cover assembly is small, the structure is simpler, and the assembly is more convenient.

[0064] Of course, the fixing seat 21 is not limited to being an exhaust valve seat, but may also be other structural members on the cover plate 2, or may be a structural member additionally provided on the cover plate 2 in order to achieve snap connection with the buckle plate 11, all without departing from the design concept of the present invention.

[0065] Preferably, if Figure 6As shown, a first mating slope 2111 is formed on the rear side of the buckle 211, and a second mating slope 1151 is formed on the front side of the hook 115. When the cover plate 2 is installed, the first mating slope 2111 cooperates with the second mating slope 1151 to squeeze the elastic buckle position 111 backwards, causing the elastic buckle position 111 to undergo elastic deformation.

[0066] When the cover 2 is installed, the first matching bevel 2111 on the buckle 211 and the second matching bevel 1151 on the hook 115 play a guiding role, so that the buckle 211 can smoothly pass over the hook 115 and fit tightly with the hook 115; and when the cover 2 is installed, the first matching bevel 2111 on the buckle 211 cooperates with the second matching bevel 1151 on the hook 115 of the elastic buckle position 111, which will squeeze the elastic buckle position 111 backwards, causing the elastic buckle position 111 to deform, making it easier for the cover 2 to be installed in the upper cover 1.

[0067] In a specific embodiment, Figure 1 As shown, the upper cover 1 includes an inner cover 12, a buckle plate 11, a sealing ring 13 and a pressure plate 14. Figures 2 to 4 As shown, the buckle plate 11 is an independent part, and two elastic buckle positions 111 are designed thereon. The surroundings and the middle of the elastic buckle positions 111 are hollowed out to improve the elasticity of the elastic buckle positions 111. When the elastic buckle positions 111 are squeezed or when the squeezing disappears, they can be moved along the Figure 3 Deform and reset in the direction shown by the arc arrow; during assembly, the gusset plate 11 with the elastic buckle position 111 is inserted into the gusset plate installation groove 121 of the inner cover 12, and specifically, the end of the elastic buckle position 111 connected to the gusset plate body 112 is inserted into the gusset plate installation groove 121 as the insertion end, and then the sealing ring 13 and the pressing plate 14 are pressed on the gusset plate 11 in sequence and press the gusset plate 11, and then the pressing plate 14, the sealing ring 13, and the inner cover 12 are locked and fixed by screws 15 to complete the assembly of the gusset plate 11 on the inner cover 12; Figure 5 and Figure 6 It is the fitting condition of the cover plate 2 after installation. When the cover plate 2 is installed, the elastic buckle position 111 will be deformed and move backward, which is conducive to the installation of the cover plate 2 and no longer requires effort. After the cover plate 2 is installed in place, the elastic buckle position 111 will reset under the elastic force generated by its own deformation, ensuring that the cover plate 2 is tightly fitted with the upper cover 1.

Of course, the cooking utensil may also be other cooking utensil with a detachable cover, such as an electric rice cooker, etc. As long as they do not deviate from the design concept of the present invention, they should be within the protection scope of the present invention.

[0071] To summarize, the upper cover assembly provided in the embodiment of the present invention, by arranging a buckle plate on the upper cover, utilizes the elastic buckle position on the buckle plate to cooperate with the snap buckle on the cover plate, so that the cover plate can be easily and effortlessly disassembled and assembled on the upper cover, and effectively solves the problem of the existing structure that the buckle position is not fastened tightly due to the large wear of the buckle position, and the problem that the buckle position has large friction and produces powder falling into the food, affecting the health of the user; and the above-mentioned elastic buckle position relies on its own elastic force to deform and reset, so that the number of parts of the entire upper cover assembly is small, the structure is simplified, the assembly is simple, and the reliability is high.
