Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, in particular to an oven inner liner manufacturing process and an oven inner liner. Background Art

[0002] In modern kitchens, electric ovens have become indispensable household appliances due to their convenient and efficient cooking characteristics. With the improvement of consumers' living standards, higher requirements are put forward for the performance and appearance of electric ovens.

[0003] Currently, the common inner liner components of electric ovens on the market mostly adopt the connection method of fastening the inner liner and the front panel with screws. This connection method exposes many drawbacks in actual use: in terms of tightness, due to the long-term influence of factors such as temperature changes and mechanical vibrations on the screws, loosening is likely to occur, resulting in a decrease in the structural stability of the inner liner, which not only affects the normal operation of the electric oven but also may pose a safety hazard; in terms of appearance, the screw connection will leave obvious installation marks on the surface of the inner liner, affecting the overall aesthetics of the product and making it difficult to meet the aesthetic needs of consumers for high-quality kitchen appliances. Summary of the Invention

[0004] The first technical problem solved by the present invention is to provide an oven inner liner manufacturing process, which effectively solves the problems of poor tightness and overall aesthetics caused by the existing manufacturing method of electric oven inner liner components. On the basis of ensuring the structural stability of the inner liner, this process can improve the overall aesthetics of the product.

[0005] The second technical problem solved by the present invention is to provide an oven inner liner, which effectively solves the problems of poor tightness and overall aesthetics of the existing electric oven inner liner components, and ensures the reliability and aesthetics of the inner liner during use.

[0006] The above first technical problem is solved by the following technical solutions:

[0007] An oven inner liner manufacturing process includes:

[0008] Preparing the front panel, the front panel having a folded edge bent towards the rear surface of the front panel;

[0009] Using the electrode plate of an energy storage welder to abut the folded edge against the rear surface of the front panel and performing welding within 1 second after abutment;

[0010] Preparing the inner liner body, the inner liner body having a folded edge extending outwards;

[0011] Using the electrode plate of an energy storage welder to abut the other side of the folded edge against the folded edge and performing welding within 1 second after abutment.

[0012] The manufacturing process of the oven inner liner described in the present invention has the following beneficial effects compared with the background technology: In this manufacturing process, since the overlapping edge is first welded to the rear surface of the front plate, and then the other side of the overlapping edge is welded to the flanging, and then the front plate is welded to the inner liner body, the stability of the inner liner structure can be ensured. And since there is no externally protruding connecting part, the overall aesthetic appearance of the product can be improved. At the same time, due to the existence of the overlapping edge, the thickness at the connection between the front plate and the flanging increases, so that when enameling the inner liner, the adhesion area of the enamel powder increases, which is more conducive to enameling. Welding within 1 second can ensure that the preheating state of the welded parts does not change, avoid inconsistent initial temperatures of the welded parts during welding, and thus affect the melting and solidification processes of the metal during welding, so as to obtain stable and high-quality solder joints.

[0025] Hemming the flanged front panel such that the first convex hull on the inner peripheral wall of the front panel protrudes toward the rear surface of the front panel with a preset spacing left and the third convex hull protrudes toward the direction of the inner container main body, so as to form a folded edge that forms a preset angle with the rear surface of the front panel.

[0026] In one embodiment, using the electrode plate of a storage energy welder to abut the folded edge against the rear surface of the front panel and performing welding within 1 second after abutment includes:

[0027] Starting the storage energy welder, and using the working current of the electrode plate to weld one side of the folded edge to the rear surface of the front panel through the first convex hull;

[0031] The spacing between the first convex hull and the rear surface of the front panel is 0.5 mm - 1 mm.

[0032] In one embodiment, the working voltage of the storage energy welder is 1 V - 11.8 V, and the working current of the storage energy welder is 10000 A - 100000 A.

[0049] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0050] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0051] This embodiment provides a manufacturing process for an oven inner liner, which can be used to prepare the inner liner in an oven and improve the overall aesthetic appearance of the oven on the basis of ensuring the structural stability of the inner liner.

[0052] As Figures 1 to 10 shown, the manufacturing process for the oven inner liner provided in this embodiment includes the following steps:

[0053] Prepare the front plate 1, and the front plate 1 has a folded edge 101 that bends towards the rear surface of the front plate 1;

[0054] Use the electrode plates of the energy storage welder to abut the folded edge 101 against the rear surface of the front plate 1 and perform welding within 1 second after abutment;

[0055] Prepare the inner liner main body 2, and the inner liner main body 2 has a folded edge 201 that extends outward;

[0056] Use the electrode plates of the energy storage welder to abut the other side of the folded edge 101 against the folded edge 201 and perform welding within 1 second after abutment.

[0057] It should be noted that the energy storage welder usually has two electrode plates, which are used in cooperation for welding.

[0058] As Figure 1As shown in the figure, the manufacturing process of the oven inner liner provided in this embodiment first prepares the front plate 1, and the front plate 1 is required to have a folded edge 101 that bends towards the rear surface of the front plate 1; then, the electrode plate of the energy storage welder is used to abut the folded edge 101 against the rear surface of the front plate 1, and welding is performed within 1 second after abutment; then, the inner liner main body 2 is prepared, and it is required that the inner liner main body 2 has a folded edge 201 extending outwards. Finally, the electrode plate of the energy storage welder is used to abut the other side of the folded edge 101 against the folded edge 201, and welding is performed within 1 second after abutment. In this manufacturing process of the oven inner liner, since the folded edge is first welded to the rear surface of the front plate, and then the other side of the folded edge is welded to the folded edge, thereby realizing welding the front plate to the inner liner main body, it can ensure the stability of the inner liner structure, and because there is no externally protruding connecting part, it can improve the overall aesthetic degree of the product. At the same time, due to the existence of the folded edge, the thickness at the connection between the front plate 1 and the folded edge 201 increases, so that when enameling the inner liner, the adhesion area of the enamel powder increases, which is more conducive to enameling. At the same time, welding within 1 second can ensure that the preheating state of the welded part does not change, avoid inconsistent initial temperatures of the welded parts during welding, and thus affect the melting and solidification processes of the metal during welding, so as to obtain stable and high-quality solder joints.

[0059] In one embodiment, after the front plate 1 and the inner liner main body 2 are welded, the inner liner is subjected to enameling treatment. Due to the existence of the flanging, the welded part is thickened, which is more conducive to enameling the inner liner.

[0060] In one embodiment, as Figures 2 to 7 shown, the preparation of the front plate 1 includes: stamping and blanking the middle part of the front plate 1; punching a number of first convex hulls 102 protruding from the inner peripheral wall of the front plate 1 after stamping and blanking from front to back; flanging the inner peripheral wall of the front plate 1 with a number of first convex hulls 102 backwards; and patting the flanged front plate 1 to form a folded edge 101 that forms a preset angle with the rear surface of the front plate 1. Among them, in the structures shown in Figure 6 and Figure 7 shown, after the flanging of the inner peripheral wall of the front plate 1 is completed, the first convex hull 102 protrudes from back to front. Specifically, the first convex hull 102 is arranged on one surface of the inner peripheral wall of the front plate 1 in the flanging direction. After the inner peripheral wall of the front plate 1 with a number of first convex hulls 102 is flanged backwards, the first convex hull 102 can be on the rear surface side of the front plate 1. During welding, the rear surface of the front plate 1 faces the inner liner main body 2.

[0061] In one embodiment, the front plate 1 after the flange is edged to form a folded edge 101 that forms a preset angle with the rear surface of the front plate 1, including: the front plate 1 after the flange is edged so that the first convex bump 102 of the inner peripheral wall of the front plate 1 protrudes toward the rear surface of the front plate 1 and leaves a preset spacing to form the folded edge 101 that forms a preset angle with the rear surface of the front plate 1. By edge-flanging the front plate 1 after the flange to form the folded edge 101, the folded edge 101 can be further bent toward the rear surface of the front plate 1 to ensure that when the folded edge 101 is subsequently welded to the rear surface of the front plate 1, the folded edge 101 can smoothly contact the rear surface of the front plate 1. At the same time, the first convex bump 102 on the folded edge 101 is set to protrude toward the rear surface of the front plate 1 and leave a preset spacing, which can prevent the first convex bump 102 from crushing the rear surface of the front plate 1 during the edge-flanging process of the front plate 1 after the flange.

[0062] In one embodiment, if Figure 4 As shown, the liner body 2 has a folded edge 201 extending outward, including: a plurality of second convex bumps 202 protruding toward the direction of the front plate 1 are formed on the folded edge 201. By forming a plurality of second convex bumps 202 protruding toward the direction of the front plate 1 on the folded edge 201, when welding, the side of the folded edge 101 facing the liner body 2 is abutted against the second convex bumps 202 on the folded edge 201, so that the side of the folded edge 101 facing the liner body 2 is welded and fixed to the folded edge 201 by melting the second convex bumps 202.

[0063] In one embodiment, preparing the front panel 1 includes: punching and blanking the middle portion of the front panel 1; punching out a plurality of first bulges 102 protruding from front to back and a plurality of third bulges (not shown in the figure) staggered with the first bulges 102 and protruding from back to front on the inner peripheral wall of the front panel 1 after the punching and blanking; flanging the inner peripheral wall of the front panel 1 on which the plurality of first bulges 102 and the third bulges are punched out backwards; and patting the front panel 1 after the flanging to form an overlapped edge 101 that forms a preset angle with the rear surface of the front panel 1. In this embodiment, a first bulge 102 and a plurality of third bulges staggered with the first bulge 102 are punched out on the opposite side walls of the inner peripheral wall of the front plate 1 after stamping and blanking. During welding, the first bulge 102 can be abutted against the inner surface of the front plate 1, and the third bulge can be abutted against the folded edge 201, so as to achieve melting of the first bulge 102 and the third bulge, and weld and fix the two sides of the folded edge 101 to the inner surface of the front plate 1 and the folded edge 201 respectively.

[0064] In one embodiment, the flanged front plate 1 is patted to form an overlapping edge 101 that forms a preset angle with the rear surface of the front plate 1, including: patting the flanged front plate 1 so that the first convex hull 102 on the inner peripheral wall of the front plate 1 protrudes toward the rear surface of the front plate 1 with a preset spacing left and the third convex hull protrudes toward the direction of the inner liner body 2 to form an overlapping edge 101 that forms a preset angle with the rear surface of the front plate 1. By patting the flanged front plate 1, the first convex hull 102 protrudes toward the rear surface of the front plate 1, so as to facilitate abutting the first convex hull 102 against the rear surface of the front plate 1 during welding. At the same time, a preset spacing is left between the first convex hull 102 and the rear surface of the front plate 1, which can prevent the first convex hull 102 from pressing and damaging the rear surface of the front plate 1 during the process of patting the flanged front plate 1. Setting a preset spacing between the first convex hull 102 and the rear surface of the front plate 1 can avoid the first convex hull 102 pressing and damaging the rear surface of the front plate 1 during the process of patting the flanged front plate 1. At the same time, by patting the flanged front plate 1, the third convex hull protrudes toward the direction of the inner liner body 2, so as to facilitate abutting the third convex hull against the surface of the folded edge 201 during welding. Wherein, the spacing b between the first convex hull 102 and the rear surface of the front plate 1 is 0.5 mm - 1 mm. Preferably, the spacing between the first convex hull 102 and the rear surface of the front plate 1 is 1 mm, and this distance can avoid the first convex hull 102 pressing and damaging the rear surface of the front plate 1 during the process of patting the flanged front plate 1.

[0065] In one embodiment, as Figure 9 and Figure 10As shown in the figure, the electrode plate of the energy storage welder is used to abut the overlapping edge 101 against the rear surface of the front plate 1, and welding is carried out within 1 second after abutment, including: starting the energy storage welder, and using the working current of the electrode plate to weld one side of the overlapping edge 101 to the rear surface of the front plate 1 through the first convex bump 102; using the electrode plate of the energy storage welder to abut the other side of the overlapping edge 101 against the folded edge 201, and welding is carried out within 1 second after abutment, including: starting the energy storage welder, and using the working current of the electrode plate to weld the other side of the overlapping edge 101 to the folded edge 201 through the convex bump on this side. Due to the provision of the first convex bump 102 and the second convex bump 202 or the third convex bump, the first convex bump 102 is arranged between the rear surface of the front plate 1 and the overlapping edge 101. During welding, the electrode plate makes the first convex bump 102 instantaneously fit together with the front plate 1 through the working current, realizing the welding of the rear surface of the front plate 1 and the overlapping edge 101. At the same time, the second convex bump 202 or the third convex bump is arranged between the overlapping edge 101 and the folded edge 201. During welding, the electrode plate makes the second convex bump 202 or the third convex bump instantaneously fit together with the overlapping edge 101 through the working current, realizing the welding of the overlapping edge 101 and the folded edge 201. Among them, as an implementation manner, the working voltage of the energy storage welder is 1V - 11.8V, and the working current is 10000A - 100000A. Preferably, the working voltage of the energy storage welder is 8V, and the working current is 80000A. Under this condition, the welding effect of the energy storage welder is better.

[0066] In one embodiment, as Figure 8 shown, in the step of flanging the rear plate 1 after flanging to form an overlapping edge 101 at a preset angle with the rear surface of the front plate 1, the preset angle a is 8° - 15°. In this embodiment, the preset angle a is preferably 10°. When the preset angle a is 10°, there is enough space between the first convex bump 102 and the rear surface of the front plate 1. At the same time, when fixing the front plate 1 and the folded edge 201 on the inner liner main body 2 through the electrode plate, the overlapping edge 101 can make the first convex bump 102 abut against the rear surface of the front plate 1 under the action of the electrode plate.

[0067] In one embodiment, stamping and blanking are carried out on the middle part of the front plate 1 blank, including: stamping a square opening in the middle part of the front plate 1 blank, and respectively stamping notches at the four corners of the square opening. By stamping a square opening in the middle part of the front plate 1 blank, it is convenient to form an overlapping edge 101 on the front plate 1 blank. At the same time, notches are respectively stamped at the four corners of the square opening, so as to facilitate the subsequent backward flanging of the inner peripheral wall of the front plate 1 after stamping and blanking.

[0068] The following takes a specific embodiment to illustrate the manufacturing process of the oven inner liner, specifically as follows:

[0069] First, a square opening is punched out in the middle of the front plate blank, and notches are punched out at the four corners of the square opening respectively; then, a plurality of first convex bumps 102 protruding from front to back are punched out on the inner wall of the front plate 1 after stamping and blanking, and the inner wall of the front plate 1 with the plurality of first convex bumps 102 punched out is flanged backward; then, the front plate 1 after flanged is patted so that the first convex bumps 102 on the inner wall of the front plate 1 protrude toward the rear surface of the front plate 1 with a spacing of 1 mm to form an overlapped edge with an angle of 10° to the rear surface of the front plate 1; then, the electrode plate of the energy storage welding machine is used to abut the overlapped edge 101 with the rear surface of the front plate 1, and welding is performed within 1 second after abutment. During welding, the first convex bumps 102 are instantly dissolved under the action of the electric current to achieve welding of the overlapped edge 101 with the rear surface of the front plate 1. Then, a folded edge 201 extending outward is formed on the peripheral side of one end of the inner tank body 2 facing the front plate 1, and a plurality of second convex bumps 202 protruding toward the direction of the front plate 1 are formed on the folded edge 201; then, the energy storage welding machine is started, and the electrode plate of the energy storage welding machine is used to abut the other side of the folded edge 101 with the folded edge 201, and welding is performed within 1 second after abutment. During welding, the second convex bump 202 is instantly dissolved under the action of the electric current to achieve welding of the folded edge 101 and the folded edge 201; finally, the inner tank is enameled.

[0070] This embodiment also provides an oven liner, comprising a front plate 1 and an liner body 2, wherein the front plate 1 and the liner body 2 are manufactured using the above-mentioned liner manufacturing process. The oven liner manufactured using the above-mentioned liner manufacturing process can ensure the stability of the liner structure, and since there is no exposed protruding connection part, the overall aesthetics of the product can be improved.

[0071] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The specific contents of the above specific embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
