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] At present, the steamers that come with steamers on the market are usually made of two types of materials and molding processes: one is food-grade plastic injection molding, such as PC steamers or PP steamers; the other is food-grade hardware material stretching molding, such as SUS304 stainless steel steamers or SUS430 stainless steel steamers. Stainless steel steamers have a longer service life than plastic steamers. The more advanced stainless steel steamers on the market are generally formed by the stamping and stretching process of hardware, that is, a whole piece of stainless steel sheet is stretched and formed. The production process usually includes blanking, stretching, punching, trimming, curling, cleaning, polishing, and re-cleaning. There are many processes and complex molding processes, which leads to a high cost of steamer production. Utility Model Content

DETAILED DESCRIPTION

[0044] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0045] 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 also 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.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0047] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may 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 intermediate medium. Moreover, a first feature being “above”, “above” or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below” or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0048] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those 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 related listed items.

[0049] See also Figures 1 to 4 The present application provides a steamer, comprising a panel 10 and a bottom plate 20, wherein the panel 10 is formed by connecting one or more plates 1 end to end. It is understood that the "plate 1" is a raw material, and the "panel 10" is a product formed after the plate 1 is processed. A first roll 11 is provided at the lower end of the panel 10, and a third roll 21 is provided at the periphery of the bottom plate 20. The first roll 11 and the third roll 21 are nested and crimped and fixed, so that the bottom plate 20 is connected to the lower end of the panel 10. It is understood that "the first roll 11 and the third roll 21 are nested" can be either the first roll 11 is nested inside the third roll 21, or the first roll 11 is nested outside the third roll 21. The steamer provided by the present application, because the bottom plate 20 and the panel 10 can be connected together by nesting and crimping the first roll 11 and the third roll 21 to form a steamer, the bottom plate 20 and the panel 10 can be prepared separately and then assembled together by a crimping process. Among them, the enclosure 10 can be formed by the plate rolling process, and the bottom plate 20 can be 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.

[0050] like Figure 2As shown, the bottom plate 20 is provided with a through hole 22 for steam circulation, and further, the bottom plate 20 is provided with a convex rib 23 and a groove 24, and 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 a through hole 22. By providing the convex rib 23, the groove 24 and the water guide groove 25, steam circulation can be facilitated, and condensed water can be discharged in time, thereby reducing the occurrence of the bottom of the food being wet.

[0051] The bottom plate 20 is made of metal material, specifically stainless steel. The plate 1 is also made of metal material, specifically stainless steel.

[0052] The bending direction of the first curl 11 is the same as that of the third curl 21. Thus, the enclosure 10 and the base plate 20 can be bent in the same direction during processing. The processing method is simple, and the first curl 11 and the third curl 21 are firmly connected.

[0053] Furthermore, the first curl 11 and the third curl 21 are both inner curls, and the first curl 11 is sleeved outside the third curl 21. In this way, the first curl 11 and the third curl 21 are both located on the inner side of the enclosure 10, thereby maintaining the beauty of the appearance of the steamer. The first curl 11 is sleeved outside the third curl 21. During processing, the third curl 21 can be processed first, and then the first curl 11 can be processed according to the appearance of the third curl 21. In this way, the processing method is relatively simple, and the first curl 11 and the third curl 21 are firmly connected after forming.

[0054] For further information, see Figure 3 and Figure 4 The lower end of the enclosure 10 is bent inward to form a folded edge 13, and one end of the folded edge 13 away from the enclosure 10 is bent downward to form a curled edge 110, and the first curled circle 11 is arranged at the free end of the curled edge 110. In this way, the first curled circle 11 will not cover the folded edge 13, and the folded edge 13 can be placed on the upper end of the pot body or the upper end of another steamer when in use, so that 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.

[0055] For further information, see Figures 3 to 5 The upper end of the enclosure 10 is provided with a second curling circle 12 bent inwardly, and the folded edge 13 of any steamer can be placed on the second curling circle 12 of another steamer. Figure 6 and Figure 7As shown, when one steamer is stacked on another steamer, the folded edge 13 of the upper steamer rests on the second curled circle 12 of the lower steamer, and the first curled circle 11 of the upper steamer is located inside the second curled circle 12 of the lower steamer. In this way, the steamer can be supported by the second curled circle 12, so that multiple steamers can be stacked together for use, greatly improving the cooking capacity. Since the second curled circle 12 is bent toward the inside of the enclosure 10, the upper end of the steamer can be prevented from protruding outward and affecting the appearance. At the same time, the second curled circle 12 cooperates with the first curled circle 11 to limit the upper steamer, preventing the upper steamer from translating and falling. Of course, for a steamer without a second curled circle on the upper end of the enclosure, when one steamer is stacked on top of another, the folded edge of the upper steamer can also be placed against the upper end of the enclosure of the lower steamer, and the first curled circle of the upper steamer is located on the inner side of the enclosure of the lower steamer. The enclosure and the first curled circle can also limit 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 be placed against the upper edge of the pot body, and the first curled circle is located on the inner side of the pot body.

[0056] like Figure 4 As shown, the edge of the bottom plate 20 is bent downward, and the third curl 21 is formed at the free end of the bottom plate 20. In this way, the third curl 21 has a very simple structure and is easy to process. Figure 8 and Fig. 9 As shown, during processing, the folding portion 13 extending inward and the curling portion 110 extending downward can be processed at the lower end of the enclosure 10 according to the size of the bottom plate 20, and then the bottom plate 20 processed with the third curling circle 21 is assembled inside the curling portion 110, and finally the free end of the curling portion 110 is bent and rolled to form the first curling circle 11 through the curling and crimping process, and is crimped and fixed together with the third curling circle 21. In this way, the first curling circle 11 will not block the folding portion 13, so that the folding portion 13 can be placed on the upper end of the pot body or the upper end of another steamer when in use. At the same time, through the cooperation of the first curling circle 11 and the third curling circle 21, the enclosure 10 and the bottom plate 20 are firmly fixed and connected as a whole, ensuring the overall structural strength of the steamer.

[0057] See also 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.

[0058] Furthermore, a bending and pressing structure 14 is provided at the joint of the head and tail of the plate 1, and the head and tail ends of the plate 1 are connected and fixed by the bending and pressing structure 14, and the bending and pressing structure 14 is located on the inner side of the enclosure 10. In this way, the head and tail ends of the plate 1 are connected by the bending and pressing structure 14, the structure is very simple and easy to process, and the bending and pressing structure 14 is hidden on the inner side of the enclosure 10, which is conducive to maintaining the beautiful appearance of the steamer.

[0059] See also Fig.10In one embodiment, the bending and crimping 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, 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 crimping 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 to achieve the fixed connection of 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.

[0060] See also Fig.11 In another embodiment, the bending crimping structure 14 includes a first bending section 148 formed at the head end of the plate 1 and bent toward the side wall of the end, a second bending section 149 formed at the tail end of the plate 1 and bent toward the side wall of the end, and a crimping member 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 member 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, 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 makes the head and tail ends of the plate 1 close to each other and firmly connected. During processing, the forming equipment applies pressure to the connection from the inside and outside of the plate 1, so that the first bending section 148, the second bending section 149 and the crimping piece 15 are tightly connected, thereby realizing the fixed connection of 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.
