Description

[0001] This application is a divisional application of patent application number 202421926128.6, filed on August 8, 2024, entitled "Steamer and Steamer". Technical Field

[0002] This application relates to the field of cooking utensil technology, and in particular to a steamer and steam pot. Background Technology

[0003] Currently, steamers commonly found with steamers on the market are typically made from two types of materials and using two different molding processes: one is food-grade plastic injection molding, such as PC or PP steamers; the other is food-grade metal materials formed through stretching, such as SUS304 or SUS430 stainless steel steamers. Stainless steel steamers have a longer lifespan than plastic steamers. Higher-end stainless steel steamers on the market generally use a stamping and stretching process for metal parts, which involves stretching a single sheet of stainless steel into shape. This process typically includes multiple steps such as blanking, stretching, punching, trimming, rolling, cleaning, polishing, and further cleaning. The numerous steps and complex molding process result in higher production costs for these steamers. Utility Model Content

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component.

[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0044] Please see Figures 1 to 4This application provides a steamer, including a side panel 10 and a bottom plate 20. The side panel 10 is formed by joining one or more sheet materials 1 end to end. It is understood that the "sheet material 1" is the raw material, and the "side panel 10" is the product formed after processing the sheet material 1. The lower end of the side panel 10 is provided with a first bent connecting portion 11, and the periphery of the bottom plate 20 is provided with a second bent connecting portion 21. One of the first bent connecting portion 11 and the second bent connecting portion 21 wraps around the other, and the bending is pressed against the lower surface of the side panel 10 or the bottom plate 20. This application achieves the assembly of the side panel 10 and the bottom plate 20 by providing the first bent connecting portion 11 and the second bent connecting portion 21, thereby forming a steamer. During production, the bottom plate 20 and the side panel 10 can be prepared separately first, and then assembled together through a bending and pressing process. Among them, the side panel 10 can be formed by steel plate rolling process, and the bottom plate 20 can be formed by stamping process. Compared with the traditional stretch forming process, stretching, trimming, polishing and other processes can be eliminated. It can be seen that this application can effectively reduce the forming process and simplify the forming process, thereby greatly reducing the production cost of the steamer, while effectively ensuring the overall structural strength of the steamer.

[0045] like Figure 2 As shown, the base plate 20 is provided with through holes 22 for steam circulation. Furthermore, the base plate 20 is provided with raised ribs 23 and grooves 24. The base plate 20 is also provided with a water guide groove 25 near the periphery, and the water guide groove 25 is also provided with through holes 22. By providing raised ribs 23, grooves 24 and water guide grooves 25, steam circulation can be facilitated, and condensate can be drained away in a timely manner, reducing the occurrence of food bottoms getting wet.

[0046] The base plate 20 is made of metal, specifically stainless steel. The plate 1 is also made of metal, specifically stainless steel.

[0047] like Figure 4 As shown, in one embodiment, the first bent connecting portion 11 includes a first portion 111 bent toward the bottom center of the surrounding plate 10 and a second portion 112 bent away from the bottom center of the surrounding plate 10. The first portion 111 and the second portion 112 enclose a first receiving groove 113. The second bent connecting portion 21 is bent toward the lower surface of the base plate 20 and inserted into the first receiving groove 113. The second portion 112 is attached to the lower surface of the base plate 20. Please refer to... Figures 5 to 7 During processing, the edge of the base plate 20 can be bent downwards to form the second bending connection part 21, such as... Figure 5 and Figure 6As shown; then, according to the shape of the second bent connecting part 21, the lower end of the surrounding plate 10 is bent so that the lower end of the surrounding plate 10 forms a downwardly extending first part 111 and an upwardly extending second part 112, and the first part 111 and the second part 112 wrap around the lower part and both sides of the second bent connecting part 21, that is, the second bent connecting part 21 is inserted into the first receiving groove 113 enclosed by the first part 111 and the second part 112, thereby forming the first assembly part, as shown. Figure 7 As shown; finally, the first assembly is bent toward the lower surface of the base plate 20, so that the second part 112 fits against the lower surface of the base plate 20, as shown. Figure 4 As shown, this completes the assembly of the enclosure panel 10 and the base plate 20. The first bending connection 11 and the second bending connection 21, designed in this way, have a simple structure, are easy to assemble and form, and ensure a firm connection between the enclosure panel 10 and the base plate 20 after forming.

[0048] Further, please see Figure 4 The lower end of the surrounding panel 10 is bent inward to form a folded edge 13. The end of the folded edge 13 away from the surrounding panel 10 is bent downward to form a first bent portion 16. A first bent connecting portion 11 is located at the free end of the first bent portion 16. Thus, after the first bent connecting portion 11 and the second bent connecting portion 21 are assembled, the folded edge 13 will not be obstructed. In use, the folded edge 13 can be rested against the upper part of the pot body or the upper part of another steamer. Figure 8 and Figure 9 As shown, the folded edge 13 can serve as the bottom edge supporting the steamer, making it easy to place the steamer on the pot or on another steamer. At the same time, a step is formed between the first bend 16 and the folded edge 13, which can limit the position of the steamer and prevent it from shifting and falling.

[0049] like Figure 10 As shown, in another embodiment, the second bent connecting portion 21 includes a first folded edge 211 extending away from the center of the base plate 20 and a second folded edge 212 bent toward the center of the base plate 20. The first folded edge 211 and the second folded edge 212 enclose a second receiving groove 213. The first bent connecting portion 11 is bent toward the lower surface of the surrounding plate 10 and inserted into the second receiving groove 213. The second folded edge 212 is attached to the lower surface of the surrounding plate 10. Please refer to [link to relevant documentation]. Figure 11During processing, a downward-extending first bent connecting portion 11 can be machined at the lower end of the surrounding plate 10. Then, the edge of the base plate 20 is bent according to the shape of the first bent connecting portion 11, so that the edge of the base plate 20 forms a downward-extending first folded edge 211 and an upward-extending second folded edge 212. The first folded edge 211 and the second folded edge 212 wrap around the lower part and sides of the first bent connecting portion 11, that is, the first bent connecting portion 11 is inserted into the second receiving groove 213 formed by the first folded edge 211 and the second folded edge 212, thereby forming a second assembly. Finally, the second assembly is bent toward the lower surface of the surrounding plate 10, so that the second part 112 fits against the lower surface of the surrounding plate 10. In this way, the assembly of the surrounding plate 10 and the base plate 20 is completed. The first bent connecting portion 11 and the second bent connecting portion 21 configured in this way have a simple structure, are easy to assemble and form, and the connection between the surrounding plate 10 and the base plate 20 is firm after forming.

[0050] Further, please see Figure 10 The lower end of the surrounding panel 10 is bent towards the bottom center to form a folded edge 13. The end of the folded edge 13 away from the surrounding panel 10 is bent downwards to form a first folded part 16. The lower end of the first folded part 16 is bent towards the bottom center of the surrounding panel 10 to form a second folded part 17. A first folded connecting part 11 is located at the free end of the second folded part 17, and a second folded edge 212 is attached to the lower surface of the second folded part 17. Thus, the area below the second folded part 17 provides space for the bending and pressing of the first folded connecting part 11 and the second folded connecting part 21, ensuring that the first folded connecting part 11 and the second folded connecting part 21 do not obstruct the folded edge 13 after assembly. In use, the folded edge 13 can be rested against the upper part of the pot body or the upper part of another steamer. Figure 12 and Figure 13 As shown, the folded edge 13 can serve as the bottom edge supporting the steamer, making it easy to place the steamer on the pot or on another steamer. At the same time, a step is formed between the first bend 16 and the folded edge 13, which can limit the position of the steamer and prevent it from shifting and falling.

[0051] Furthermore, the upper end of the partition panel 10 is provided with an inwardly curved roll 12, so that the folded edge 13 of any steamer can rest against the roll 12 of another steamer. Figure 8 and Figure 9As shown, when one steamer is stacked on top of another, the folded edge 13 of the upper steamer rests against the rolled circle 12 of the lower steamer, and the first bent part 16 of the upper steamer is located inside the rolled circle 12 of the lower steamer. In this way, the rolled circle 12 supports the steamer, making it easy to stack multiple steamers together and greatly increasing cooking capacity. Because the rolled circle 12 bends inward towards the side panel 10, it prevents the upper part of the steamer from bulging outward and affecting its appearance. At the same time, the rolled circle 12, in conjunction with the first bent part 16, helps to limit the movement of the upper steamer, preventing it from shifting and falling. Of course, for steamers without a rolled-up top edge on the side panel, when one steamer is stacked on top of another, the folded edge of the upper steamer can rest against the upper edge of the side panel of the lower steamer. The first bent part of the upper steamer is located inside the side panel of the lower steamer. The side panel and the first bent part cooperate to limit the movement of the upper steamer, preventing it from shifting and falling. In other embodiments, when the steamer is placed on the pot body, the folded edge can rest against the upper edge of the pot body, and the first bent part 16 is located inside the pot body.

[0052] Please see Figures 1 to 3 In this embodiment, the enclosure 10 is formed by connecting one sheet 1 end to end, resulting in a simpler structure. Of course, in other embodiments, the enclosure can also be formed by connecting multiple sheets end to end.

[0053] Furthermore, a bending and pressing structure 14 is provided at the joint of the two ends of the board 1. The two ends of the board 1 are connected and fixed by the bending and pressing structure 14, which is located inside the enclosure 10. In this way, the two ends of the board 1 are connected by the bending and pressing structure 14. The structure is very simple and easy to process. Moreover, the bending and pressing structure 14 is hidden inside the enclosure 10, which helps to maintain the aesthetic appearance of the steamer.

[0054] Please see Figure 14 In one embodiment, the bending and pressing structure 14 includes a first side 141, a second side 142, a third side 143, and a fourth side 144 formed at the beginning of the sheet 1 and connected in sequence, and a fifth side 145 and a sixth side 146 formed at the end of the sheet 1 and connected in sequence. The second side 142 and the fourth side 144 are arranged in parallel, and the second side 142, the third side 143, and the fourth side 144 enclose a slot 147, into which the sixth side 146 is inserted. Thus, the beginning and end ends of the sheet 1 form a U-shaped structure that interlocks, resulting in a secure connection. In this embodiment, the bending and pressing structure 14 is pressed together from the inside and outside of the surrounding plate 10 by a forming device, thereby achieving a fixed connection between the beginning and end ends of the sheet 1. This connection method does not require the use of fasteners such as screws and rivets, nor does it require welding, making the processing simpler and the structure simpler.

[0055] Please see Figure 15 In another embodiment, the bending and pressing structure 14 includes a first bent section 148 formed at the first end of the plate 1 and bent toward the side wall of that end, a second bent section 149 formed at the tail end of the plate 1 and bent toward the side wall of that end, and a pressing member 15 independent of the plate 1. The first bent section 148 and the second bent section 149 are located on the same side of the plate 1. The pressing member 15 includes a first pressing section 151, a second pressing section 152, and a third pressing section 153 connected in sequence. The first pressing section 151 and the third pressing section 153 are formed by bending the two ends of the second pressing section 152 toward the center of the same side. The first pressing section 151 and the second pressing section 152 enclose a first pressing groove 154, and the third pressing section 153 and the second pressing section 152 enclose a second pressing groove 155. The first bent section 148 is inserted into the first pressing groove 154, and the second bent section 149 is inserted into the second pressing groove 155. Thus, both ends of the sheet 1 form U-shaped structures, and both ends of the pressing member 15 also form U-shaped structures. The first end of the sheet 1 interlocks with one end of the pressing member 15, and the last end of the sheet 1 interlocks with the other end of the pressing member 15. The pressing member 15 brings the first and last ends of the sheet 1 closer together, ensuring a firm connection. During processing, pressure is applied to the connection point from both the inside and outside of the sheet 1 using a forming device, which tightly connects the first bending section 148, the second bending section 149, and the pressing member 15, thereby achieving a fixed connection between the first and last ends of the sheet 1. This connection method does not require the use of fasteners such as screws and rivets, nor does it require welding, making the processing simpler and the structure simpler.

[0056] Please see Figure 1 and Figure 2 Furthermore, the steamer also includes two handles 30 connected to opposite sides of the enclosure 10. At least one handle 30 is connected to the joint between the ends of the board 1 and is fixedly connected to both ends of the board 1. In this way, at least one handle 30 further strengthens the structural strength of the joint between the ends of the board 1, preventing the ends of the board 1 from loosening. The two handles 30 are located on opposite sides of the enclosure 10, making it convenient for users to take the steamer, and the design is also aesthetically pleasing. In this embodiment, the enclosure 10 is formed by the joint of a board 1 end to end, and one handle 30 is connected to the joint between the ends of the board 1.

[0057] In this embodiment, the handle 30 is connected to the enclosure 10 by screws, making the installation of the handle 30 very simple. The handle 30 can be made of high-temperature resistant plastic, which has a lower thermal conductivity than metal, thus avoiding injury from excessively high temperatures during prolonged heating.

[0058] Please combine Figures 16 to 20 The forming process of assembling the side panel 10 and the bottom plate 20 to form the main body of the steamer is as follows: 1. Blanking and punching to obtain blank sheet material, which is plate 1. Plate 1 is rectangular, such as... Figure 16 As shown. The left and right ends of the sheet 1 are provided with bending and pressing forming areas 14', the lower end of the sheet 1 is provided with a first forming area 11', and the upper end of the sheet 1 is provided with a second forming area 12'. II. Bending and pressing: The sheet 1 is bent and the bending and pressing forming areas 14' at both ends are as shown. Figure 14 The bending and pressing shown are joined together, or as shown Figure 15 As shown, after adding the pressing component 15, the parts are bent and pressed together to form a bent and pressed structure 14, as shown. Figure 17 As shown. III. Pre-forming: The sheet material 1 is shaped into the final form. In this embodiment, it is shaped into a rectangle, as shown... Figure 18 As shown, in other embodiments, it can also be arranged into a circle or a square. Fourth, forming: the second forming area 12' is rolled into a circle 12, and the first forming area 11' is folded to form a folded edge 13 and a first bent part 16, resulting in the enclosure 10 before assembly with the base plate 20, as shown. Figure 19 and Figure 20 As shown. V. Assemble the base plate 20 and the surrounding plate 10, to... Figure 4 Taking the structure shown as an example, the base plate 20 with the downwardly extending second bent connecting portion 21 is assembled inside the first bent portion 16, as follows. Figure 5 and Figure 6 As shown. Then, the lower end of the first bending portion 16 is bent upwards so that the lower end of the first bending portion 16 forms a first bending connecting portion 11 that wraps around the second bending connecting portion 21, as shown. Figure 7 As shown; finally, the first bent connecting part 11 and the second bent connecting part 21 are bent and pressed together toward the lower surface of the base plate 20, so that the second part 112 of the first bent connecting part 11 is attached to the lower surface of the base plate 20, thereby assembling the base plate 20 and the surrounding plate 10 together, as shown. Figure 3 and Figure 4 As shown.

[0059] This application also provides a steamer, including the steaming basket described above. Because this steamer includes the aforementioned steaming basket, the forming process of the steaming basket is simple and the manufacturing cost is low; therefore, the production cost of this steamer is also low. The steamer can be an electric steamer, a steamer heated by an open flame, or a steamer used with an induction cooker.
