Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a cooking appliance. Background Art

[0002] An electric rice cooker or electric pressure cooker generally comprises a cooker body and a cooker cover fitted on the cooker body. The cooker body comprises an outer shell, a heat preservation cover located inside the outer shell, an inner pot located inside the heat preservation cover, and a middle ring located on the upper part of the heat preservation cover. A circuit board assembly and a heating device are also provided inside the cooker body. The circuit board assembly can supply power to the electronic components inside the cooking utensil and realize corresponding control. The heating device can heat the food in the inner pot to realize cooking.

[0003] In the prior art, there are generally two ways to fix the power board assembly:

[0004] Method 1: The circuit board assembly is provided with positioning plates on both sides of its top for connecting with the upper middle ring, and is fixed to the upper middle ring separately by screws passing through the positioning plates. This fixing method requires multiple screws for fixing, which is cumbersome to assemble and has low assembly efficiency. In addition, the center of gravity of the circuit board assembly as a whole is close to the bottom of the circuit board assembly. Fixing the circuit board assembly separately to the upper middle ring results in poor stability of the circuit board assembly after assembly. When the circuit board assembly is subjected to radial force along the outer shell during use or transportation, it is easy to cause the circuit board assembly to shake, affecting the stability of the electrical connection.

[0005] Method 2: The circuit board assembly is provided with a positioning plate extending toward one side of the heating device, and the heating device is provided with a positioning lug extending toward the positioning plate to be located above the positioning plate. The circuit board assembly is fastened to the upper middle ring by screws that are sequentially passed through the positioning plate and the positioning lug. Due to the limited space between the circuit board assembly and the heating device, the operating space is narrow during the assembly process, and it is inconvenient to insert the assembly tooling, which limits the process of tightening the screws and seriously affects the assembly efficiency.

[0006] In order to solve the problems existing in the above two fixing methods, patent document CN209404388U discloses a cooking utensil, including a middle ring, a heat preservation cover, a heating device, a base and a power board assembly. The middle ring is provided with a protrusion, and the power board assembly is provided with a recess. The protrusion extends into the recess to realize mutual limitation between the middle ring and the power board assembly. The side wall of the heat preservation cover is provided with a convex column extending along the axial direction of the heat preservation cover, and a first mounting structure is formed on the convex column. The heating device is provided with a second mounting structure, the power board assembly is provided with a third mounting structure, and the base is provided with a fourth mounting structure. The screws pass through the first mounting structure, the second mounting structure, the third mounting structure and the fourth mounting structure to fix the heat preservation cover, the heating device, the power board assembly and the base together. The middle ring is provided with a positioning column extending downward, and the heat preservation cover and the base are respectively provided with support columns connected to the positioning column. The middle ring is fixed to the heat preservation cover and the base by screws passing through the support columns and the positioning columns. The cooking utensil has the following defects: the structure of the heat preservation cover is complicated, and a boss for connecting to the power board assembly needs to be separately provided on the heat preservation cover in order to fix the power board assembly, and the bottom end of the boss abuts against the top end surface of the second mounting structure, resulting in that sufficient attention needs to be paid during the assembly of the heat preservation cover, the heating device and the power board assembly in order to achieve the alignment of the boss with the second mounting structure and the third mounting structure in the axial direction. If there is an error in the axial direction, the screws cannot be installed, and the assembly efficiency is greatly reduced; the middle ring and the power board assembly are only limited to each other, and the installation and fixation of the middle ring requires the provision of separate fasteners and mounting structures to achieve the installation and fixation of the middle ring, resulting in a large number of screws used in the assembly of the entire pot body, which is not only costly but also affects the assembly efficiency.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0021] 1. The middle ring in the present application is provided with a first mounting column, the heating device is provided with a first mounting through hole, and the circuit board bracket is provided with a mounting arm. One of the first mounting column and the mounting arm is provided with a first convex portion, and the other of the two is provided with a first concave portion. At least a portion of the first convex portion passes through the first mounting through hole and extends into the first concave portion, so that during the assembly process, the middle ring, the heating device and the circuit board bracket can form a modular structure to achieve mutual limitation between each other, which is convenient for assembling the three as a component with other components in the pot body, which not only ensures the relative position relationship between the three and improves the assembly efficiency between the three and other components in the pot body, but also the middle ring, the heating device and the circuit board bracket are the main components of the pot body. After the three are mutually limited by the first convex portion, the first concave portion and the first mounting through hole, the installation position and relative position of the remaining components used to constitute the pot body are basically determined, thereby providing a position reference for the assembly of the remaining components constituting the pot body, which helps to improve the assembly efficiency of the entire pot body.

[0022] Furthermore, by the first protrusion extending through the first mounting through hole into the first recess, a tight fit can be formed between the middle ring, the heating device and the circuit board bracket, thereby improving the stability of the overall structure after assembly.

[0023] In addition, the first protrusion extends into the first recess through the first mounting hole, which can reduce the height size of the pot body to a certain extent, reduce the extra space occupied, make the overall design more compact, and contribute to the miniaturization of the cooking utensil.

[0024] 2. As a preferred embodiment of the present application, the base is provided with a second mounting column, the second mounting column is provided with a third mounting through hole, the mounting arm is provided with a second mounting through hole, and the circuit board bracket is clamped and fixed between the first mounting column and the second mounting column by fasteners passing through the third mounting through hole, the second mounting through hole and the first mounting column, that is, the above-mentioned installation method is used to assemble once by fasteners to realize both the installation and fixation of the circuit board bracket and the installation and fixation of the middle ring, killing two birds with one stone, and greatly improving the assembly efficiency of the pot body. In addition, after assembly, the circuit board bracket is clamped and fixed between the first mounting column and the second mounting column, thereby providing additional support for the circuit board bracket, improving the stability of the circuit board bracket after assembly, reducing the probability of vibration and displacement of the circuit board bracket during transportation and use, and providing a guarantee for the stability of the circuit board operation during the operation of the cooking appliance.

Of course, during the disassembly process, the above-mentioned limiting matching method also provides a guarantee for the smooth disassembly.

[0026] 3. As a preferred embodiment of the present application, the heating device includes a wire reel rack, and the wire reel rack is provided with a positioning lug extending laterally outward, and the first mounting through hole is provided on the positioning lug. The positioning lug extending laterally outward is provided to realize the alignment of the wire reel rack with the first mounting column and the mounting arm. To a certain extent, the laterally extending positioning lug can be utilized to make up for the distance between the wire reel rack and the circuit board bracket, thereby reducing the arm span length of the mounting arm. After the circuit board and the circuit board bracket are assembled, the center of gravity of the two is reduced compared to the force arm of the first protrusion or the first recess on the mounting arm, thereby reducing the shear force brought by the center of gravity of the two after assembly on the fasteners and the connection position passing through the mounting arm, which not only makes the assembly of the circuit board bracket more stable, but also can reduce the stress concentration problem at the connection position, thereby extending the service life of the circuit board bracket.

[0027] 4. As a preferred embodiment of the present application, the circuit board bracket is provided with a plurality of mounting arms, which can, on the one hand, reduce the stress concentration phenomenon at the connection position after assembly, and on the other hand, realize multiple cooperation limits with the middle ring and the heating device, thereby improving the stability of the circuit board bracket after assembly with the middle ring and the heating device.

[0028] 5. As a preferred embodiment of the present application, the circuit board bracket is provided with a first positioning structure, and the middle ring is provided with a second positioning structure. The circuit board bracket and the middle ring are limited to each other by the first positioning structure and the second positioning structure, so as to achieve further positioning of the circuit board bracket.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a cooking utensil comprises a pot body, a heating device and a circuit board bracket 2 located at one side of the heating device, the pot body comprises a base 4 and a middle ring 1 located above the base 4, the middle ring 1 is provided with a first mounting column 11 extending toward the base 4, the heating device is provided with a first mounting through hole 312, the circuit board bracket 2 is provided with a mounting arm 21 extending toward one side of the heating device, one of the first mounting column 11 and the mounting arm 21 is provided with a first protrusion 111, and the other is provided with a first recess 211, and at least a portion of the first protrusion 111 passes through the first mounting through hole 312 and extends into the first recess 211.

After the three are mutually limited by the first protrusion 111, the first recess 211 and the first mounting through hole 312, the installation position and relative position of the remaining components used to constitute the pot body are basically determined, thereby providing a position reference for the assembly of the remaining components constituting the pot body, which helps to improve the assembly efficiency of the entire pot body.

[0049] Furthermore, by the first protrusion 111 extending through the first mounting through hole 312 and into the first recess 211 , a tight fit can be formed between the middle ring 1 , the heating device and the circuit board bracket 2 , thereby improving the stability of the overall structure after assembly.

[0050] In addition, the first protrusion 111 extends into the first recess 211 through the first mounting hole 312, which can reduce the height of the pot body to a certain extent, reduce the extra space occupied, make the overall design more compact, and contribute to the miniaturization of the cooking utensil.

[0051] As a preferred embodiment of the present application, Figures 1 to 3 As shown, the circuit board bracket 2 includes a bracket body, one end of the mounting arm 21 is connected to the bracket body, and the other end extends toward the heating device. The circuit board bracket 2 also includes a reinforcing plate 23 connecting the bracket body and the mounting arm 21 to enhance the connection strength between the mounting arm 21 and the bracket body, thereby ensuring the stable installation of the circuit board bracket 2.

[0052] The present application does not limit the structural shape of the first protrusion 111, which may be a cylinder, a prism, a cone, etc. Correspondingly, the first mounting through hole 312 and the first recess 211 may be adaptively changed.

[0053] The assembly method of the circuit board mounting frame in the present application can adopt any one of the following implementations:

[0054] Embodiment 1: The mounting arm 21 is provided with a second mounting through hole 213, and the fastener passes through the second mounting through hole 213 to connect and fix the mounting arm 21 to the first mounting column 11. That is, in this embodiment 1, the circuit board bracket 2 is locked and fixed to the middle ring 1 by fasteners. This embodiment 1 does not limit the fixing method of the middle ring 1: in one embodiment, the pot body also includes a heat preservation cover, and the middle ring 1 is fixed to the heat preservation cover by a snap connection and / or other fasteners; in another embodiment, the middle ring 1 is provided with a third mounting column extending toward the base 4, the third mounting column is provided with a mounting hole adapted to other fasteners, the base 4 is provided with a fourth mounting column corresponding to the third mounting column, and the middle ring 1 is locked and fixed to the base 4 by fasteners passing through the fourth mounting column and the mounting hole.

[0055] Implementation method 2: Figures 3 to 5 As shown, the mounting arm 21 is provided with a second mounting through hole 213, the base 4 is provided with a second mounting column 41 extending upward, the second mounting column 41 is provided with a third mounting through hole 43, and the mounting arm 21 is clamped and fixed between the first mounting column 11 and the second mounting column 41 by fasteners passing through the third mounting through hole 43, the second mounting through hole 213 and the first mounting column 11. That is, the second embodiment is adopted to perform one-time assembly through fasteners to realize both the installation and fixation of the circuit board bracket 2 and the installation and fixation of the middle ring 1, killing two birds with one stone, and greatly improving the assembly efficiency of the pot body. Moreover, after assembly, the circuit board bracket 2 is clamped and fixed between the first mounting column 11 and the second mounting column 41, thereby providing additional support for the circuit board bracket 2, improving the stability of the circuit board bracket 2 after assembly, reducing the probability of vibration and displacement of the circuit board bracket 2 during transportation and use, and providing a guarantee for the stability of the circuit board operation during the operation of the cooking appliance. In addition, compared with the fixing method of the circuit board bracket in the prior art, the second embodiment adopts the method of tightening the fasteners from the bottom of the base 4 to achieve the installation and fixation of the circuit board bracket 2 and the middle ring 1. The operating space during the assembly process is relatively large, and the process of tightening the fasteners is convenient and easy, which helps to reduce the difficulty of assembly and improve assembly efficiency.

[0056] As one of the examples under the second embodiment, the bottom end surface of the mounting arm 21 is a plane, and the plane abuts against the top end surface of the second mounting post 41 .

[0057] As a preferred embodiment of the second embodiment, Figure 5As shown, one of the mounting arm 21 and the second mounting column 41 is provided with a second protrusion 212, and the other is provided with a second recess 42 adapted to the second protrusion 212, and at least part of the second protrusion 212 extends into the second recess 42, so as to provide pre-positioning for the circuit board bracket 2 and the base 4 during the assembly process of the circuit board bracket 2 and the base 4, and with the mutual limitation between the middle ring 1, the heating device and the circuit board bracket 2 through the first protrusion 111, the first mounting through hole 312 and the first recess 211, the assembly efficiency of the middle ring 1, the heating device, the circuit board bracket 2 and the base 4 can be further improved. Of course, during the disassembly process, the above-mentioned limiting matching method also provides a guarantee for the smooth disassembly.

[0058] Furthermore, if Figure 5 As shown, one of the second protrusion 212 and the second recess 42 is provided with a guide surface 2121, and the other is provided with a matching surface 421 adapted to the guide surface 2121. Through the matching of the guide surface 2121 and the matching surface 421, it is convenient to align the mounting arm 21 with the second mounting column 41 during the assembly process, further improving the assembly efficiency. Preferably, at least one of the guide surface 2121 and the matching surface 421 is an inclined surface.

[0059] In one example, the first protrusion 111 and the second recess 42 are provided on the mounting arm 21 , the first recess 211 is provided on the first mounting post 11 , and the first protrusion 111 is provided on the second mounting post 41 .

[0060] In a preferred example, Figure 5 As shown, the first protrusion 111 is provided on the first mounting column 11, the second recess 42 is provided on the second mounting column 41, and the first recess 211 and the second protrusion 212 are provided on the mounting arm 21. Providing the first protrusion 111 on the first mounting column 11 and the first recess 211 on the mounting arm 21 helps to shorten the length of the fastener to a certain extent, and the installation and fixation of the circuit board bracket 2 can be achieved without providing special fasteners. On this basis, the second protrusion 212 adapted to the second recess 42 is provided on the mounting arm 21, which helps to improve the structural strength of the mounting arm 21, increase the structural strength of the mounting arm 21 at the connection position, and ensure the stability of the circuit board bracket 2 after installation.

[0061] The heating device in the present application can adopt any one of the following embodiments:

[0062] Embodiment 3: The heating device comprises a heating plate, a heating element arranged on the heating plate, and a heating plate bracket for mounting the heating plate. The heating plate bracket is provided with a positioning lug extending laterally outward, and the first mounting through hole 312 is provided on the positioning lug.

[0063] Implementation method 4: Figures 3 to 5As shown, the heating device includes a wire drum rack 3 and an electromagnetic coil wound on the wire drum rack 3, and the wire drum rack 3 is provided with a positioning lug 31 extending laterally outward, and the first mounting through hole 312 is provided on the positioning lug 31. By providing the positioning lug 31 extending laterally outward, the wire drum rack 3 is aligned with the first mounting column 11 and the mounting arm 21. To a certain extent, the distance between the wire drum rack 3 and the circuit board bracket 2 can be compensated by the positioning lug 31 extending laterally, and the arm span length of the mounting arm 21 can be reduced. After the circuit board and the circuit board bracket 2 are assembled, the center of gravity of the two is reduced compared with the force arm of the first protrusion 111 or the first recess 211 on the mounting arm 21, thereby reducing the shear force caused by the center of gravity of the two after assembly to the fastener and the connection position passing through the mounting arm 21, which not only makes the assembly of the circuit board bracket 2 more stable, but also can reduce the problem of stress concentration at the connection position, and extend the service life of the circuit board bracket 2.

[0064] As one of the examples under the fourth embodiment of the present invention, the wire drum rack 3 is fixedly connected to the base 4 through other mounting through holes and fasteners thereon. The first mounting through hole 312 plays a role of pre-positioning the wire drum rack 3 in this embodiment.

[0065] As a preferred embodiment of the fourth embodiment, the positioning lug 31 is clamped and fixed between the first mounting column 11 and the mounting arm 21. That is, for this embodiment, when the circuit board bracket 2 is installed and fixed, the cable drum bracket can be installed and fixed simultaneously.

[0066] As a preferred embodiment of the present application, Figure 1 and Figure 2 As shown, the circuit board bracket 2 is provided with a plurality of mounting arms 21. Such an arrangement can, on the one hand, reduce the stress concentration phenomenon at the connection position after assembly, and on the other hand, realize the multiple matching limits with the middle ring 1 and the heating device, thereby improving the stability of the circuit board bracket 2, the middle ring 1 and the heating device after assembly.

[0067] As a preferred embodiment of the present application, the circuit board bracket 2 is provided with a first positioning structure, and the middle ring 1 is provided with a second positioning structure. The circuit board bracket 2 and the middle ring 1 are limited to each other by the first positioning structure and the second positioning structure, thereby achieving further positioning of the circuit board bracket 2. During transportation and operation of the cooking utensil, if there is vibration, the mutual limitation method between the circuit board bracket 2 and the middle ring 1 in this embodiment can further prevent the circuit board bracket 2 from shaking, thereby further providing a guarantee for the reliability and stability of the circuit board operation.

[0068] In one embodiment, one of the first positioning structure and the second positioning structure is a buckle, and the other is a buckle position adapted to the buckle, and the buckle can be snapped into the buckle position to achieve mutual limitation of the circuit board bracket 2 and the middle ring 1.

[0069] As a preferred embodiment of this implementation, Figure 6 and Figure 7 As shown, one of the first positioning structure and the second positioning structure is a third protrusion 12 , and the other is a third recess 22 matched with the third protrusion 12 , and at least a portion of the third protrusion 12 extends into the third recess 22 .

[0070] The circuit board bracket 2 has two opposite sides along a first direction and two opposite sides along a second direction perpendicular to the first direction. The two opposite sides along the first direction are a mounting side facing the heating device and a functional side facing away from the mounting side and used to mount circuit components. As a preferred embodiment of this embodiment, Figure 1 , Figure 2 and Figure 7 As shown, there are two first positioning structures, the two first positioning structures are located at two opposite sides along the second direction, and the first positioning structure includes two positioning parts arranged side by side along the first direction. For example, the two positioning parts are respectively the third recess 22. Such an arrangement, on the one hand, will not occupy the installation space of the functional side of the circuit board bracket 2, so as to leave more space for the functional side to install various circuit components. On the other hand, the circuit board bracket 2 can be limited along the first direction through the two positioning parts, further improving the limiting effect of the circuit board bracket 2, avoiding the shaking of the circuit board bracket 2, and providing a guarantee for the normal operation of the circuit components.

[0071] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0072] 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.

[0073] The above is only the embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
