Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to a steamer and a steamer. Background Art

[0002] Currently, steamer baskets used with steamers on the market are typically made from two types of materials and molding processes: one is injection-molded from food-grade plastic, such as PC or PP steamers; the other is drawn from food-grade hardware, 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 are typically formed using a hardware stamping and drawing process, where a single sheet of stainless steel is stretched and formed. The production process typically includes multiple steps, including blanking, drawing, punching, trimming, curling, cleaning, polishing, and further cleaning. The complex molding process and numerous steps lead to higher production costs. Utility Model Content

[0046] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0047] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0049] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediary.

When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.

[0050] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0051] See Figures 1 to 4The present application provides a steamer, including an enclosure 10 and a bottom plate 20, wherein the enclosure 10 is formed by connecting one or more plates 1 end to end. It can be understood that the "plate 1" is the raw material, and the "enclosure 10" is the product formed after the plate 1 is processed. A first bending connection portion 11 is provided at the lower end of the enclosure 10, and a second bending connection portion 21 is provided at the periphery of the bottom plate 20. One of the first bending connection portion 11 and the second bending connection portion 21 wraps the other, and is bent and pressed onto the lower surface of the enclosure 10 or the bottom plate 20. The present application can realize the assembly of the enclosure 10 and the bottom plate 20 by providing the first bending connection portion 11 and the second bending connection portion 21, thereby forming a steamer. During production and processing, the bottom plate 20 and the enclosure 10 can be prepared separately first and then assembled together through a bending and pressing process. Among them, the enclosure 10 can be processed and formed by the plate rolling process, and the bottom plate 20 can be processed and formed by the stamping process. Compared with the traditional stretching forming process, the stretching, trimming, polishing and other processes can be omitted. It can be seen that the present application can effectively reduce the forming process flow and simplify the forming process, thereby greatly reducing the production cost of the steamer, while effectively ensuring the overall structural strength of the steamer.

[0052] like Figure 2 As shown, the bottom plate 20 is provided with through holes 22 for steam circulation. Furthermore, the bottom plate 20 is provided with ribs 23 and grooves 24. The bottom plate 20 is also provided with a water guide groove 25 near the peripheral area, and the water guide groove 25 is also provided with through holes 22. The provision of the ribs 23, grooves 24, and water guide grooves 25 facilitates steam circulation and facilitates the timely drainage of condensed water, thereby reducing the possibility of the bottom of the food getting wet.

[0053] The bottom plate 20 is made of metal material, specifically stainless steel. The plate 1 is also made of metal material, specifically stainless steel.

[0054] 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 enclosure 10 and a second portion 112 bent away from the bottom center of the enclosure 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 bottom plate 20 and inserted into the first receiving groove 113. The second portion 112 is attached to the lower surface of the bottom plate 20. Figures 5 to 7 During processing, the edge of the bottom plate 20 may be bent downward to form a second bent connecting portion 21. Figure 5 and Figure 6As shown; the lower end of the enclosure 10 is bent according to the shape of the second bent connecting portion 21, so that the lower end of the enclosure 10 forms a first portion 111 extending downward and a second portion 112 extending upward, and the first portion 111 and the second portion 112 are wrapped below and on both sides of the second bent connecting portion 21, that is, the second bent connecting portion 21 is inserted into the first receiving groove 113 enclosed by the first portion 111 and the second portion 112, thereby forming a first combination portion, as shown Figure 7 Finally, bend the first assembly portion toward the lower surface of the bottom plate 20 so that the second portion 112 is attached to the lower surface of the bottom plate 20, as shown. Figure 4 As shown, the assembly of the enclosure 10 and the bottom plate 20 is completed. The first bent connecting portion 11 and the second bent connecting portion 21 provided in this way have a simple structure and are easy to assemble and form, and the enclosure 10 and the bottom plate 20 are firmly connected after forming.

[0055] Further, see Figure 4 The lower end of the panel 10 is bent inward to form a folded edge 13. The end of the folded edge 13 away from the panel 10 is bent downward to form a first folded portion 16. The first folded connection portion 11 is provided at the free end of the first folded portion 16. In this way, the first folded connection portion 11 and the second folded connection portion 21 will not block the folded edge 13 after being assembled. When in use, the folded edge 13 can be placed on the upper end of the pot body or the upper end of another steamer, such as Figure 8 and Figure 9 As shown, the folded edge 13 can serve as the bottom edge of the steamer to support the steamer, making it easy to place the steamer on the pot body or on another steamer. At the same time, a step is formed between the first bent portion 16 and the folded edge 13 to limit the position of the steamer and prevent the steamer from falling off.

[0056] like Figure 10 As shown, in another embodiment, the second bent connection portion 21 includes a first folded edge 211 extending away from the center of the bottom plate 20 and a second folded edge 212 bent toward the center of the bottom plate 20. The first folded edge 211 and the second folded edge 212 enclose a second receiving groove 213. The first bent connection portion 11 is bent toward the lower surface of the enclosure 10 and inserted into the second receiving groove 213. The second folded edge 212 is attached to the lower surface of the enclosure 10. Figure 11During processing, a first bent connection portion 11 extending downward can be processed at the lower end of the enclosure 10, and then the edge of the bottom plate 20 can be bent according to the shape of the first bent connection portion 11, so that the edge of the bottom plate 20 forms a first folded edge 211 extending downward and a second folded edge 212 extending upward, and the first folded edge 211 and the second folded edge 212 are wrapped below and on both sides of the first bent connection portion 11, that is, the first bent connection portion 11 is inserted into the second receiving groove 213 enclosed by the first folded edge 211 and the second folded edge 212, thereby forming a second combination portion, and finally the second combination portion is bent toward the lower surface of the enclosure 10 so that the second portion 112 is attached to the lower surface of the enclosure 10, thus completing the assembly of the enclosure 10 and the bottom plate 20. The first bent connection portion 11 and the second bent connection portion 21 set in this way have a simple structure and are easy to assemble and form, and the enclosure 10 and the bottom plate 20 are firmly connected after forming.

[0057] Further, see Figure 10 The lower end of the enclosure 10 is bent toward the bottom center to form a folded edge portion 13, and the end of the folded edge portion 13 away from the enclosure 10 is bent downward to form a first folded portion 16. The lower end of the first folded portion 16 is bent toward the bottom center of the enclosure 10 to form a second folded portion 17. The first bent connection portion 11 is provided at the free end of the second bent portion 17, and the second folded edge 212 is attached to the lower surface of the second bent portion 17. In this way, the lower part of the second bent portion 17 provides space for the bending and crimping of the first bent connection portion 11 and the second bent connection portion 21, so that the first bent connection portion 11 and the second bent connection portion 21 will not block the folded edge portion 13 after assembly. When in use, the folded edge portion 13 can be placed on the upper end of the pot body or the upper end of another steamer, such as Figure 12 and Figure 13 As shown, the folded edge 13 can serve as the bottom edge of the steamer to support the steamer, making it easy to place the steamer on the pot body or on another steamer. At the same time, a step is formed between the first bent portion 16 and the folded edge 13 to limit the position of the steamer and prevent the steamer from falling off.

[0058] Furthermore, the upper end of the enclosure 10 is provided with a curl 12 that is bent inwards, so that the folded edge 13 of any steamer can be placed on the curl 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 on the curled portion 12 of the lower steamer, and the first bent portion 16 of the upper steamer is located inside the curled portion 12 of the lower steamer. This allows the steamers to be supported by the curled portion 12, making it easier to stack multiple steamers together and significantly increasing cooking capacity. Because the curled portion 12 curves inwardly toward the enclosure 10, it prevents the upper end of the steamer from protruding outward, affecting its appearance. Furthermore, the curled portion 12 and the first bent portion 16 act as a position limiter for the upper steamer, preventing it from shifting and falling. Of course, for steamers without a curved upper end of the panel, when one steamer is stacked on top of another, the folded edge of the upper steamer can also rest against the upper end of the panel of the lower steamer, with the first bent portion of the upper steamer located inside the panel of the lower steamer. The panel and the first bent portion can also function as a position limiter for the upper steamer, preventing the upper steamer 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, with the first bent portion 16 located inside the pot body.

[0059] See Figures 1 to 3 In this embodiment, the enclosure 10 is formed by connecting a plate 1 end to end, and the structure is simpler. Of course, in other embodiments, the enclosure can also be formed by connecting multiple plates end to end.

[0060] Furthermore, a bending and pressing structure 14 is provided at the end where the sheet 1 meets its end. The bending and pressing structure 14 connects and fixes the ends of the sheet 1. The bending and pressing structure 14 is located inside the enclosure 10. Thus, the bending and pressing structure 14 connects the ends of the sheet 1, making the structure very simple and easy to manufacture. Moreover, the bending and pressing structure 14 is hidden inside the enclosure 10, which helps to maintain the beautiful appearance of the steamer.

[0061] 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 head end of the plate 1 and connected in sequence, and a fifth side 145 and a sixth side 146 formed at the tail end of the plate 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, and the sixth side 146 is inserted into the slot 147. In this way, the head and tail ends of the plate 1 form a U-shaped structure that interlocks with each other and is firmly connected. In this embodiment, the bending and pressing structure 14 is squeezed from the inside and outside of the enclosure 10 by a forming device to press the second side 142, the fourth side 144 and the sixth side 146 together to achieve a fixed connection between the head and tail ends of the plate 1. This connection method does not require the use of fasteners such as screws and rivets, nor does it require welding processing. The processing process is simpler and the structure is also simpler.

[0062] See Figure 15 In another embodiment, the bending and crimping structure 14 includes a first bending section 148 formed at the front end of the plate 1 and bent toward the side wall of the end, a second bending section 149 formed at the rear end of the plate 1 and bent toward the side wall of the end, and a crimping piece 15 independent of the plate 1. The first bending section 148 and the second bending section 149 are located on the same side of the plate 1. The crimping piece 15 includes a first crimping section 151, a second crimping section 152, and a third crimping section 153 connected in sequence. The first crimping section 151 and the third crimping section 153 are formed by bending the two ends of the second crimping section 152 toward the center of the same side. The first crimping section 151 and the second crimping section 152 enclose a first crimping groove 154, and the third crimping section 153 and the second crimping section 152 enclose a second crimping groove 155. The first bending section 148 is inserted into the first crimping groove 154, and the second bending section 149 is inserted into the second crimping groove 155. In this way, both ends of the plate 1 form a U-shaped structure, and both ends of the crimping piece 15 also form a U-shaped structure. The head end of the plate 1 is interlocked with one end of the crimping piece 15, and the tail end of the plate 1 is interlocked with the other end of the crimping piece 15. The crimping piece 15 brings the head and tail ends of the plate 1 closer together and firmly connects. During processing, the forming equipment applies pressure to the connection from the inside and outside of the plate 1, so that the first bend section 148, the second bend section 149 and the crimping piece 15 are tightly connected, thereby achieving a fixed connection between the head and tail ends of the plate 1. This connection method does not require the use of fasteners such as screws and rivets, nor does it require welding processing. The processing process is simpler and the structure is also simpler.

[0063] See Figure 1 and Figure 2 Furthermore, the steamer also includes two handles 30 connected to opposite sides of the panel 10, with at least one handle 30 connected to the end-to-end junction of the plate 1 and fixedly connected to both ends of the plate 1. In this way, at least one handle 30 further strengthens the structural strength of the end-to-end junction of the plate 1, preventing the end ends of the plate 1 from loosening. The two handles 30 are arranged on opposite sides of the panel 10, making it convenient for users to take the steamer and having an aesthetically pleasing appearance. In this embodiment, the panel 10 is formed by enclosing a plate 1 connected end to end, and one of the handles 30 is connected to the end-to-end junction of the plate 1.

[0064] In this embodiment, the handle 30 is connected to the enclosure 10 by screws, and it is very simple to install the handle 30. The handle 30 can be made of high-temperature resistant plastic, which has a lower thermal conductivity than metal, to avoid excessive temperature and injury when heated for a long time.

[0065] Please combine Figures 16 to 20 The forming process of assembling the enclosing plate 10 and the bottom plate 20 to form the main part of the steamer is as follows: 1. Blanking and punching to obtain blanking sheet material, which is the plate material 1. The plate material 1 is rectangular, such as Figure 16 As shown. The left and right ends of the plate 1 are provided with bending and pressing forming areas 14', the lower end of the plate 1 is provided with a first forming area 11', and the upper end of the plate 1 is provided with a second forming area 12'. 2.
