Description

[Technical Field]

[0001] This invention relates to the field of kitchen appliance technology, and more particularly to a method for assembling cooking utensils. [Background Technology]

[0002] In the prior art, cooking appliances include a shell, an inner pot, and a heating plate. The heating plate is pre-installed with multiple connecting posts for fasteners at circumferential intervals. The side of the heating plate away from the connecting posts is fixed to the bottom of the inner pot by brazing. During brazing, pressure needs to be applied to the center of the heating plate towards the inner pot so that the molten brazing material connects the bottom of the heating plate and the inner pot. Since the part of the heating plate with connecting posts is located outside the center and no pressure is applied to the inner pot during brazing, the heating plate will deform due to uneven stress. This will cause the connecting posts to deviate excessively towards the center of the heating plate, making it impossible for the connecting posts to be connected to the corresponding bottom wall of the shell by fasteners. As a result, the connection between the shell and the inner pot cannot be completed, which brings great difficulty to the assembly of the cooking appliance. [Summary of the Invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method for assembling a cooking appliance, which can effectively avoid excessive deviation of the connecting column, thereby facilitating the connection between the shell and the connecting column and reducing the assembly difficulty of the cooking appliance.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A method for assembling a cooking appliance, the cooking appliance comprising a shell, an inner pot, and a heating plate, the assembly method comprising:

[0006] S100 The heating plate is circumferentially spaced with multiple connecting posts for connecting fasteners, and the connecting posts are inclined towards the edge of the heating plate from their root to their free end.

[0007] The side of the heating plate opposite to the connecting post described in S200 is fixed to the bottom of the inner liner by brazing. The deflection of the connecting post is used to compensate for the deflection of the connecting post caused by the deformation of the heating plate during the brazing process.

[0008] The shell and connecting column of S300 are connected by fasteners to complete the assembly of the inner liner and the shell.

[0009] In the above-mentioned method for assembling cooking appliances, in step S100, the connecting column is fixed to the heating plate by riveting.

[0010] In the above-mentioned method for assembling cooking utensils, in step S100, the central axis of the connecting column is tilted 5° to 15° relative to the axis of the heating plate towards the edge of the heating plate.

[0011] In the above-mentioned method for assembling cooking appliances, the heating plate includes a metal heat-conducting plate and an electric heating element disposed on the metal heat-conducting plate. The electric heating element is coiled around the metal heat-conducting plate, and a plurality of connecting posts are circumferentially spaced on the metal heat-conducting plate outside the electric heating element.

[0012] In the above-mentioned method for assembling cooking appliances, in step S200, the heating element is brazed and fixed to the metal heat-conducting plate, and the brazing of the heating element to the metal heat-conducting plate and the brazing of the metal heat-conducting plate to the inner pot are carried out simultaneously.

[0013] In the above-mentioned method of assembling cooking appliances, during the brazing process, pressure is simultaneously applied to the metal heat-conducting plate inside the heating element and the heating element in the direction of the inner pot.

[0014] In the above-mentioned method of assembling cooking appliances, during the brazing process, pressure is simultaneously applied to the metal heat-conducting plate on the outside of the heating element in the direction of the inner pot.

[0015] In the above-mentioned assembly method of cooking appliances, the distance between the root of the connecting post and the edge of the metal heat-conducting plate is ≥5mm, and the distance between the root of the connecting post and the heating element is ≥3mm.

[0016] In the above-described method for assembling cooking appliances, the housing includes a base and an annular outer shell, and step S300 includes:

[0017] The S310 assembles the inner liner with the heating plate welded on to the annular outer shell, with the opening of the inner liner snapped onto the upper end of the annular outer shell.

[0018] The S320 connects the base and the connecting post with fasteners, with the edge of the base abutting the lower end of the annular housing.

[0019] In the above-mentioned method for assembling cooking appliances, the fastener is a screw, the housing is provided with a mounting hole, the connecting post is provided with a screw hole, and in step S300, the horizontal projections of the mounting hole and the screw hole at least partially overlap, and the screw passes through the mounting hole and is locked in the screw hole.

[0020] The beneficial effects of this invention are:

[0021] In the cooking appliance assembly method of the present invention, the connecting post is first pre-installed on the heating plate, and the root of the connecting post to its free end is tilted towards the edge of the heating plate. Then, the side of the heating plate opposite to the connecting post is brazed and fixed to the bottom of the inner pot. Since the deformation of the heating plate when it is brazed and fixed to the bottom of the inner pot will cause the connecting post to tilt towards the center of the heating plate, that is, tilt in the opposite direction of the tilt when the connecting post is pre-installed, the deformation of the heating plate can compensate for the tilt of the connecting post when it is pre-installed, thereby realizing the correction and straightening of the connecting post. This avoids the excessive tilt of the connecting post after the heating plate and the inner pot are brazed in the prior art. This makes it easier to connect the connecting post and the shell with fasteners and reduces the assembly difficulty of the cooking appliance.

[0022] The connecting posts are fixed to the heating plate by riveting. This design results in higher production efficiency, lower costs, and better reliability as the connecting posts are less likely to fall off.

[0023] In step S100, the central axis of the connecting column is offset towards the edge of the heating plate at a angle of 5° to 15° relative to the axis of the heating plate. Because existing connecting columns may exhibit an inward offset of 5° to 15° due to manufacturing limitations, this solution offsets the central axis of the connecting column towards the edge of the heating plate at a angle of 5° to 15°. This significantly reduces or even eliminates the offset caused by heating plate deformation. In actual production, the pre-offset angle of the connecting column towards the edge of the heating plate can be adjusted according to the actual situation to achieve the optimal state of complete alignment.

[0024] The heating plate includes a metal heat-conducting plate and heating elements mounted on the metal heat-conducting plate. The heating elements are coiled around the metal heat-conducting plate, and multiple connecting posts are circumferentially spaced on the metal heat-conducting plate outside the heating elements. This design allows the heating elements to heat the inner pot evenly, while also reserving space inside the heating elements for other electronic components of the cooking appliance, making the heating plate structure more compact.

[0025] In step S200, the heating element is brazed and fixed to the metal heat-conducting plate, and the brazing of the heating element to the metal heat-conducting plate and the brazing of the metal heat-conducting plate to the inner pot are carried out simultaneously. This design allows the fixed connection between the heating element and the metal heat-conducting plate, as well as the fixed connection between the metal heat-conducting plate and the inner pot, to be completed in one brazing process, thereby reducing assembly steps and improving the assembly efficiency of the cooking appliance.

[0026] During the brazing process, pressure is simultaneously applied towards the inner liner to both the inner metal heat-conducting plate and the heating element. This design allows the brazing filler metal to fully fill the gaps between the metal heat-conducting plate and the inner liner, as well as between the heating element and the metal heat-conducting plate, thereby improving the connection reliability between the heating element and the metal heat-conducting plate.

[0027] During brazing, pressure is simultaneously applied towards the inner liner to the metal heat-conducting plate on the outside of the heating element. This design ensures more uniform force on the metal heat-conducting plate, reducing deformation of the bottom of the inner liner caused by uneven force during brazing. Furthermore, it reduces the deformation of the portion of the metal heat-conducting plate located outside the heating element, thus reducing the angle at which the connecting post deviates towards the center of the heating plate. This, in turn, reduces the angle at which the connecting post deviates towards the edge of the heating plate after pre-installation.

[0028] The distance between the base of the connecting post and the edge of the metal heat-conducting plate is ≥5mm, and the distance between the base of the connecting post and the heating element is ≥3mm. Even after correction, the connecting post may still have a slight misalignment. This design limits the distance between the base of the connecting post and the heating element to prevent contact between them and reduce heat transfer to the connecting post, thus reducing heat transfer to the housing and preventing high-temperature deformation of the housing. Furthermore, the limited distance between the base of the connecting post and the edge of the metal heat-conducting plate ensures the reliability of the connection and prevents cracking of the metal heat-conducting plate after drilling due to excessive proximity to the edge.

[0029] The housing includes a base and an annular outer shell. Step S300 includes: S310 assembling the inner pot with the heating plate welded to it to the annular outer shell, with the opening of the inner pot snapped into the upper end of the annular outer shell; S320 connecting the base and the connecting post with fasteners, with the edge of the base abutting against the lower end of the annular outer shell. This design allows for pre-positioning of the inner pot by snapping it into the upper end of the annular outer shell, facilitating the subsequent fastener connection between the base and the connecting post, thereby reducing the assembly difficulty of the cooking appliance. Furthermore, the connection between the base and the heating plate allows the annular outer shell to be clamped and fixed between the base and the opening of the inner pot, eliminating the need for additional fasteners to connect the opening of the inner pot to the upper end of the annular outer shell, further reducing the assembly difficulty of the cooking appliance.

[0030] The fastener is a screw. The housing has mounting holes, and the connecting post has screw holes. In step S300, the horizontal projections of the mounting holes and screw holes at least partially overlap. The screw passes through the mounting hole and is locked in the screw hole. This design allows for a detachable connection between the inner liner and the base, facilitating later maintenance of the heating element. Furthermore, the screw connection between the housing and the connecting post ensures reliable connection while reducing assembly difficulty and improving product assembly efficiency.

[0031] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0040] This invention provides a method for assembling a cooking appliance, the cooking appliance comprising a shell, an inner pot, and a heating plate, the assembly method comprising:

[0041] S100 The heating plate is circumferentially spaced with multiple connecting posts for connecting fasteners, and the connecting posts are inclined towards the edge of the heating plate from their root to their free end.

[0042] The side of the heating plate opposite to the connecting post described in S200 is fixed to the bottom of the inner liner by brazing. The deflection of the connecting post is used to compensate for the deflection of the connecting post caused by the deformation of the heating plate during the brazing process.

[0043] The shell and connecting column of S300 are connected by fasteners to complete the assembly of the inner liner and the shell.

[0044] In the cooking appliance assembly method of the present invention, the connecting post is first pre-installed on the heating plate, and the root of the connecting post to its free end is tilted towards the edge of the heating plate. Then, the side of the heating plate opposite to the connecting post is brazed and fixed to the bottom of the inner pot. Since the deformation of the heating plate when it is brazed and fixed to the bottom of the inner pot will cause the connecting post to tilt towards the center of the heating plate, that is, tilt in the opposite direction of the tilt when the connecting post is pre-installed, the deformation of the heating plate can compensate for the tilt of the connecting post when it is pre-installed, thereby realizing the correction and straightening of the connecting post. This avoids the excessive tilt of the connecting post after the heating plate and the inner pot are brazed in the prior art. This makes it easier to connect the connecting post and the shell with fasteners and reduces the assembly difficulty of the cooking appliance.

[0045] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0046] Example 1

[0047] Reference Figures 1 to 5 As shown, the cooking appliance in this embodiment is an electric hot pot, including a shell 100, an inner pot 200, and a heating plate 300. The assembly method of the cooking appliance includes:

[0048] S100 heating plate 300 is circumferentially spaced with multiple connecting posts 310 for connecting fasteners, and the connecting posts 310 are inclined towards the edge of the heating plate from their root to their free end.

[0049] The side of the S200 heating plate 300 facing away from the connecting post 310 is fixed to the bottom of the inner liner 200 by brazing. The deflection of the connecting post 310 is used to compensate for the deflection of the connecting post 310 caused by the deformation of the heating plate 300 during the brazing process.

[0050] The S300 housing 100 and the connecting post 310 are connected by fasteners to complete the assembly of the inner liner 200 and the housing 100.

[0051] In the cooking appliance assembly method of this embodiment, the connecting post 310 is first pre-installed on the heating plate 300, and the root of the connecting post 310 to its free end is tilted towards the edge of the heating plate. Then, the side of the heating plate 300 away from the connecting post 310 is brazed and fixed to the bottom of the inner pot 200. Since the deformation of the heating plate 300 when it is brazed and fixed to the bottom of the inner pot 200 will cause the connecting post 310 to tilt towards the center of the heating plate 300, that is, tilt in the opposite direction of the tilt when the connecting post 310 is pre-installed, the deformation of the heating plate 300 can compensate for the tilt of the connecting post 310 during pre-installation, thereby correcting and straightening the connecting post 310. This avoids the excessive tilt of the connecting post 310 after the heating plate 300 and the inner pot 200 are brazed in the prior art. This facilitates the connection of the connecting post 310 and the shell 100 by fasteners and reduces the assembly difficulty of the cooking appliance.

[0052] Specifically, the heating plate 300 in this embodiment includes a metal heat-conducting plate 320 (e.g., an aluminum plate, a steel plate, etc.) and an electric heating element 330 disposed on the metal heat-conducting plate 320. The metal heat-conducting plate 320 is brazed and fixed to the bottom of the inner liner 200. When the metal heat-conducting plate 320 is fixed to the bottom of the inner liner 200, the portion of the metal heat-conducting plate 320 located inside the electric heating element 330 is subjected to pressure in the direction of the inner liner 200, while the portion of the metal heat-conducting plate 320 located outside the electric heating element 330 is not subjected to pressure. This causes the portion of the metal heat-conducting plate 320 located outside the electric heating element 330 to deform, causing the connecting column 310 to deflect towards the center of the heating plate 300. The heating element 330 is a heating tube, which is coiled around the side of the metal heat-conducting plate 320 away from the inner pot 200. Multiple connecting posts 310 are circumferentially spaced on the metal heat-conducting plate 320 outside the heating element 330. This design enables the heating element 330 to heat the inner pot 200 evenly, and also leaves space inside the heating element 330 to arrange other electronic components of the cooking appliance, thus making the structure of the heating plate 300 more compact.

[0053] In this embodiment, the connecting post 310 is pre-installed on the metal heat-conducting plate 320 by riveting. This design can improve production efficiency, reduce costs, and make the connecting post 310 less likely to fall off, thus improving reliability.

[0054] Since a through hole for the connecting post 310 to pass through needs to be made in the metal heat-conducting plate 320 before riveting the connecting post 310 to the metal heat-conducting plate 320, in order to avoid the metal heat-conducting plate 320 cracking when drilling due to the through hole being too close to it, in this embodiment, the distance between the root of the connecting post 310 and the edge of the metal heat-conducting plate 320 is ≥5mm, that is, the distance between the through hole and the edge of the metal heat-conducting plate 320 is ≥5mm. This design can avoid the metal heat-conducting plate 320 cracking after drilling due to the through hole being too close to the edge of the metal heat-conducting plate, and at the same time ensure the connection reliability of the connecting post 310. Furthermore, in this embodiment, the distance between the root of the connecting post 310 and the heating element 330 is ≥3mm. This is because after the connecting post 310 is corrected, there may still be a small amount of misalignment in the connecting post 310. Therefore, limiting the distance between the root of the connecting post 310 and the heating element 330 can prevent the connecting post 310 from contacting the heating element 330, and at the same time reduce the heat transferred to the connecting post 310, thereby reducing the heat transferred from the connecting post 310 to the housing 100 and preventing the housing 100 from deforming at high temperature.

[0055] Because the connecting post 310 in the prior art may be misaligned inward within a range of 5° to 15° due to the limitations of the manufacturing process, in order to greatly reduce or even eliminate the misalignment of the connecting post 310 caused by the deformation of the metal heat-conducting plate 320, in step S100 of this embodiment, after the connecting post 310 is riveted and fixed, the central axis of the connecting post 310 is misaligned relative to the axis of the heating plate 300 (i.e., the axis of the metal heat-conducting plate 320) towards the edge of the heating plate at an angle α of 5° to 15°. With this design, the misalignment of the connecting post 310 caused by the deformation of the metal heat-conducting plate 320 can be greatly reduced or even eliminated. Preferably, in actual production, the pre-misalignment angle of the connecting post 310 towards the edge of the heating plate 300 can be adjusted within a range of 5° to 15° according to the actual deformation of the metal heat-conducting plate 320, so as to achieve the best state of complete alignment.

[0056] In addition, the heating element 330 in this embodiment is also fixed to the metal heat-conducting plate 320 by brazing. In step S200, the brazing of the heating element 330 to the metal heat-conducting plate 320 and the brazing of the metal heat-conducting plate 320 to the inner pot 200 are carried out simultaneously. With this design, the fixed connection between the heating element 330 and the metal heat-conducting plate 320 and the metal heat-conducting plate 320 and the inner pot 200 can be completed in one brazing, thereby reducing the assembly steps and improving the assembly efficiency of the cooking appliance.

[0057] Preferably, during the brazing process in step S200, pressure needs to be simultaneously applied towards the inner liner 200 to the metal heat-conducting plate 320 inside the heating element 330, the heating element 330, and the metal heat-conducting plate 320 outside the heating element 330. Specifically, three pressure blocks 400 are respectively provided on the metal heat-conducting plate 320 inside the heating element 330, the heating element 330, and the metal heat-conducting plate 320 outside the heating element 330 to simultaneously press the surfaces of the metal heat-conducting plate 320 inside the heating element 330, the heating element 330, and the metal heat-conducting plate 320 outside the heating element 330. This design ensures proper metal heat conduction. The plate 320 is subjected to more uniform force, which reduces the deformation of the bottom of the inner liner 200 caused by uneven force during brazing. In addition, it can reduce the deformation of the part of the metal heat-conducting plate 320 located outside the heating element 330, thereby reducing the angle of the connecting post 310 deflection towards the center of the heating plate 300. This can reduce the angle of the connecting post 310 deflection towards the edge of the heating plate 300 after it is pre-installed in the heating plate 300. Finally, this design can also ensure that the brazing filler metal fully fills the gap between the metal heat-conducting plate 320 and the inner liner 200, as well as the gap between the heating element 330 and the metal heat-conducting plate 320, thereby improving the connection reliability of the heating element 330 and the metal heat-conducting plate 320.

[0058] Finally, the housing 100 of this embodiment includes a base 110 and an annular outer shell 120. After completing step S200 of assembling the inner liner 200 and the heating plate 300, step S300 is executed, wherein step S300 includes: S310 assembling the inner liner 200 with the heating plate 300 welded on it and the annular outer shell 120. The opening of the inner liner 200 has an inverted U-shaped flange 210, which is snapped into the upper end of the annular outer shell 120; then step S320 is executed, that is, the base 110 and the connecting post 310 are connected by fasteners, and the edge of the base 110 abuts against the lower end of the annular outer shell 120. This design allows the inner pot 200 to be pre-positioned by the snap-fit ​​between the inner pot 200 and the upper end of the annular outer shell 120, facilitating the later fastener connection between the base 110 and the connecting post 310, thereby reducing the assembly difficulty of the cooking appliance. In addition, the connection between the base 110 and the heating plate 300 allows the annular outer shell 120 to be clamped and fixed between the base 110 and the opening of the inner pot 200, eliminating the need for additional fasteners to connect and fix the opening of the inner pot 200 to the upper end of the annular outer shell 120, thus further reducing the assembly difficulty of the cooking appliance.

[0059] To reduce the assembly difficulty in step S320, the fastener in this embodiment is a screw. The base 110 has mounting holes, and the connecting post 310 has screw holes. It should be noted that by correcting and straightening the connecting post 310 in step S200, it can be ensured that after step 200 is completed, the horizontal projections of the mounting holes and screw holes at least partially overlap, so that in step S320, the screw can be locked into the screw hole after passing through the mounting hole. This design enables the detachable connection between the inner liner 200 and the base 110, which facilitates the later maintenance of the heating plate 300. In addition, the screw connection between the base 110 and the connecting post 310 also reduces the assembly difficulty and improves the assembly efficiency of the product while ensuring the reliability of the connection between the shell 100 and the connecting post 310.

[0060] It is understood that in other embodiments of the present invention, during the brazing process, pressure may be applied simultaneously to the metal heat-conducting plate inside the heating element and the heating element in the direction of the inner liner, that is, two pressure blocks are respectively set on the metal heat-conducting plate and the heating element located inside the heating element.

[0061] It is understood that in other embodiments of the present invention, the connecting column may also be fixed to the metal heat-conducting plate by spot welding.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
