Description

Technical Field

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

[0002] At present, there are usually two structural forms of steamers that come with steamers on the market: one is a steamer with a bottom, that is, the bottom and the side of each layer of the steamer are an integrated and non-detachable structure. When multiple layers of steamers are stacked for steaming, the height of each layer of the steamer cannot be changed. When using this type of steamer for cooking, the height of the food is more sensitive to the size, and food that exceeds the height of the steamer cannot be steamed; the other is a bottomless steamer, that is, the upper and lower mouths of the steamer are through, and the bottomless steamer only has the side of the steamer and no bottom structure of the steamer. The function of supporting the food at the bottom of the steamer is replaced by a special part-the steaming grid. That is, compared with a steamer with a bottom, a bottomless steamer divides the side of the steamer and the bottom of the steamer into two separate parts-the steamer and the steamer. In this way, the height of each layer of the steamer can be flexibly configured. For example, two bottomless steamers are stacked without placing a steaming grid between the two steamers, so that a height space twice that of a single-layer steamer can be obtained. Users can flexibly configure the height of each layer of the steamer according to their needs.

[0003] Obviously, among the two structural forms of steamers, the bottomless steamer can flexibly configure the height of each layer of the steamer and can adapt to more cooking scenarios. The user experience of the bottomless steamer is better than that of the steamer with a bottom.

[0004] However, the current production process of bottomless steamers made of stainless steel is generally to stretch a whole piece of stainless steel material and then cut off the bottom of the steamer to ensure the overall structural strength of the bottomless steamer. However, the bottomless steamer produced in this way has many molding processes and complex molding processes, and the material consumption of cutting off the discarded bottom of the steamer is large, and the cost of parts production is high.

The bottomless steamer 100 is arranged on the pot body, and the steaming rack 200 is detachably arranged at the upper end or the lower end of the steamer body 10. When in use, according to the height of the steamed food, multiple bottomless steamers 100 can be stacked together for use, or can be used in conjunction with the steaming rack 200. The steaming rack 200 can be placed at the lower end of the steamer body 10 or at the upper end of the steamer body 10. Fig.15 and Fig.16 As shown, two bottomless steamers 100 are stacked together for use, and a steaming rack 200 can be arranged between the two bottomless steamers 100, so that the edge of the steaming rack 200 is clamped between the first coil 11 of the upper bottomless steamer 100 and the second coil 12 of the lower bottomless steamer 100. Since the steamer includes the above-mentioned steamer, the above-mentioned steamer forming process is simple and the manufacturing cost is low, so the production cost of the steamer is also low. The steamer can be an electric steamer or a common steamer, that is, a steamer used with an open flame.

[0077] Further, when the steaming rack 200 is disposed at the lower end of the steamer body 10, there are two situations, such as Fig.16 As shown, in one embodiment, the lower end of the side wall of the steamer body 10 is placed on the edge of the steaming grid 200. In this embodiment, the lower end of the steamer body 10 is provided with a folded edge portion 13 and a first curled circle 11, and the edge of the steaming grid 200 is correspondingly arranged in a step structure, the folded edge portion 13 at the lower end of the steamer body 10 is placed on the step structure of the edge of the steaming grid 200, and the first curled circle 11 is located inside the step structure of the steaming grid 200. In another embodiment (not shown), the steaming grid 200 is arranged in the steamer body 10, and the edge of the steaming grid 200 is placed on the folded edge portion 13. In this way, the folded edge portion 13 can stably support the steaming grid 200. Regardless of which of the above two situations, by setting the steaming grid 200 at the lower end of the steamer body 10, it is equivalent to assembling a steamer with a bottom, and compared with a steamer with a bottom, the bottomless steamer 100 and the steaming grid 200 are more flexible to use in combination.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments 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.

[0079] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
