Description

Technical Field

[0001] The invention relates to the technical field of steaming racks, in particular to a multifunctional steaming rack and a steaming rack system. Background Art

[0002] Steaming is an important cooking method. Most of the food consumed by Chinese residents is steamed. Steaming is a method of heating with steam, which makes the ingredients of the seasoned dishes mature or crispy. Steaming preserves the original shape, juice and flavor of the dishes, and can preserve the various nutrients of the dishes to a large extent. Steamed dishes are fresh and fragrant, tender and refreshing, beautiful in shape and color, with less loss of original juice, and are not easy to mix flavors, which preserves the original form of the ingredients to the greatest extent.

[0003] At present, a steaming grid is usually used in the process of steaming dishes. The steaming grid is placed above a pot filled with water, and then the dishes are placed on the steaming grid, and then a lid is buckled and sealed on the steaming grid or the pot, so that the water in the pot generates a large amount of water vapor after heating, and then the food on the steaming grid is steamed by the water vapor. However, existing steaming grids are all of fixed specifications, and a steaming grid of one specification can only be used with an electric rice cooker or other pot body of corresponding specifications and sizes; if steaming grids of different specifications are used in conjunction with an electric rice cooker or other pot body, a large amount of water vapor will be leaked due to the loose sealing between the steaming grid and the electric rice cooker or other pot body, thereby extending the steaming time of the food and even causing the taste of the food to deteriorate; so in order to avoid this phenomenon, most families do not prepare multiple steaming grids so that they can select a suitable steaming grid for various steaming situations, which reduces the practicality of the steaming grid.

[0027] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of this patent.

[0028] Example 1

[0029] like Figure 1 and Figure 2As shown, the present embodiment discloses a multifunctional steaming rack, including a steaming rack body 1 and a lower annular rubber pad 2; the steaming rack body 1 and the lower annular rubber pad 2 are connected up and down, and the steaming rack body 1 is provided with at least one through-going vent hole 11; the outer contour of the lower annular rubber pad 2 is adapted to the outer contour of the steaming rack body 1 in the radial direction and the circumferential direction. The lower annular rubber pad 2 is connected to the lower surface of the steaming rack body 1 to seal the lower annular rubber pad 2 and the steaming rack body 1, and then the lower annular rubber pad 2 on the lower surface of the steaming rack body 1 is placed on the pot mouth of an electric rice cooker or other pot body, so that the lower annular rubber pad 2 forms a seal with the pot mouth of electric rice cookers or other pot bodies of different specifications; or the steaming rack body 1 is placed in a spherical pot, and the outer contour of the lower annular rubber pad 2 on the lower surface of the steaming rack body 1 contacts and squeezes the surface of the spherical pot, so that the outer contour of the lower annular rubber pad 2 automatically forms a seal with the spherical pot. The steam is sealed; the dishes on the steaming grid body are steamed through the vent holes 11 of the steaming grid body 1; the design of the lower annular rubber pad 2 on the lower surface of the steaming grid body 1 enables the same steaming grid body 1 to be suitable for steaming dishes in electric rice cookers or other pots of multiple specifications, eliminating the need to prepare multiple steaming grids at home at the same time, and effectively avoiding the phenomenon of water vapor leaking along the contact between the steaming grid body 1 and the electric rice cooker or other pots, thereby improving the working efficiency of steaming food, ensuring the taste of the dishes, and improving the practicality. In addition, the middle part of the steaming grid body 1 is in a concave cone shape, and the lower end of the cone is connected to the vent hole, thereby avoiding the phenomenon of water accumulation in the middle part of the steaming grid body 1.

[0030] In this embodiment, a circle of multiple evenly distributed through holes 15 is provided on the circumference of the outer contour of the steaming grid body 1, and a convex column 13 is provided at the position of the lower annular rubber pad 2 corresponding to part or all of the through holes 15 of the steaming grid body 1, and the lower annular rubber pad 2 is embedded in the through holes 15 of the steaming grid body 1 through the convex column 23 to connect the lower annular rubber pad 2 with the steaming grid body 1; or the steaming grid body 1 is provided with two circles of multiple evenly distributed through holes on the circumference of the outer contour, and a convex column is provided at the position of the lower annular rubber pad 2 corresponding to part or all of the through holes on each circle of the steaming grid body 1, and the lower annular rubber pad 2 is embedded in the through holes 15 of the steaming grid body 1 through the convex column 23 to connect the lower annular rubber pad 2 with the steaming grid body 1. The connection between the lower annular rubber pad 2 and the steaming grid body 1 is achieved by embedding the convex column 23 in the through hole 15, which facilitates the disassembly and assembly of the lower annular rubber pad 2 and the steaming grid body 1, and ensures the sealing between the lower annular rubber pad 2 and the steaming grid body 1. Of course, the lower annular rubber pad 2 and the steaming tray body 1 can be connected by bonding, which can further improve the sealing between the lower annular rubber pad 2 and the steaming tray body 1.

[0031] Example 2

[0032] like Figure 3As shown, the components and their connection relationships included in this embodiment are basically the same as those in embodiment 1, except that the multifunctional steaming tray further includes an upper annular rubber pad 3, which is connected to the upper surface of the steaming tray body 1, and the outer contour of the upper annular rubber pad 3 is adapted to the outer contour of the steaming tray body 1 in the radial direction and the circumferential direction. The design of the upper annular rubber pad 3, when the bottom edge of a steamer or a steamer basket or other steaming utensils is placed on the upper annular rubber pad 3 of the steaming tray body 1, avoids the phenomenon of water vapor leaking along the contact area between the upper annular rubber pad 3 and the bottom edge of the steamer or the steamer basket or other steaming utensils, and can ensure the sealing between the upper annular rubber pad 3 and the bottom edge of the steamer or the steamer basket or other steaming utensils, further improving the working efficiency of the steaming tray body 1 when it is used.

[0033] Example 3

[0034] like Figure 4 As shown, the components and their connection relationship included in this embodiment are basically the same as those in embodiment 2, except that the multifunctional steaming tray also includes a middle connecting rubber ring 4; the outer contour edges of the upper annular rubber pad 3 and the lower annular rubber pad 2 are connected through the middle connecting rubber ring 4, and the space formed by the upper annular rubber pad 3, the middle connecting rubber ring 4 and the lower annular rubber pad 2 wraps the edge of the steaming tray body 1 therein, and the outer part of the connection between the middle connecting rubber ring 4 and the lower annular rubber pad 2 is transitioned through an arc surface. The design of the middle connecting rubber ring 4 makes the outer contour of the steaming tray body 1 smoother and rounder, avoiding the phenomenon that the steaming tray body 1 is deformed due to direct collision of foreign objects with the outer contour of the steaming tray body 1, thereby protecting the steaming tray body 1; the outer part of the connection between the middle connecting rubber ring 4 and the lower annular rubber pad 2 is transitioned through an arc surface, which is convenient for sealing the contact surface of the steaming tray body 1 with the spherical pot when the steaming tray body 1 is placed in the spherical pot. The upper annular rubber pad 3, the middle connecting rubber ring 4 and the lower annular rubber pad 2 are split structures or integrated structures; when the upper annular rubber pad 3, the middle connecting rubber ring 4 and the lower annular rubber pad 2 are integrated structures, the middle connecting rubber ring and the lower annular rubber pad can be regarded as the return bend flange set on the outer edge of the upper annular rubber pad, thereby eliminating the processing of the middle connecting rubber ring and the lower annular rubber pad, so that the one-time molding preparation of the upper annular rubber pad containing the return bend flange can meet the requirements.

[0035] Example 4

[0036] like Figure 5As shown, the components and connection relationships included in this embodiment are basically the same as those in Embodiment 3, except that the upper annular rubber pad 3 is provided with a plurality of upper annular protrusions 5 with the same central axis and different diameters, the plurality of upper annular protrusions 5 with different diameters are arranged at equal intervals on the upper annular rubber pad 3, and the contours of the plurality of upper annular protrusions 5 in the radial direction of the upper annular rubber pad are in the shape of a wave line; the lower annular rubber pad 2 is provided with a plurality of lower annular protrusions with the same central axis and different diameters, the plurality of lower annular protrusions with different diameters are arranged at equal intervals on the lower annular rubber pad, and the contours of the plurality of lower annular protrusions in the radial direction of the lower annular rubber pad 2 are in the shape of a wave line. The annular protrusions are provided for both the upper annular rubber pad 3 and the lower annular rubber pad 2, so that the upper and lower surfaces of the steaming tray body 1 can be used, that is, the upper annular rubber pad 3 can be used to place the steamer or the pot mouth of the electric rice cooker or other pot body, and the lower annular rubber pad 2 can be used to place the steamer or the pot mouth of the electric rice cooker or other pot body. In addition, the bottom edge of the steamer is placed between two adjacent annular protrusions of different diameters, and the two annular protrusions are respectively in contact with the inner and outer surfaces of the bottom edge of the steamer, thereby improving the seal between the bottom edge of the steamer and the upper annular rubber pad 3 or the lower annular rubber pad 2, and avoiding the phenomenon of loose sealing caused by the uneven bottom edge of the steamer. In addition, the inner contour of the upper annular rubber pad 3 is provided with a downwardly bent flange, and the bent flange of the upper annular rubber pad 3 wraps the inner contour of the steaming frame body 1 therein.

[0037] Another implementation of this embodiment is that a plurality of annular protrusions with the same central axis and different diameters are provided on the upper annular rubber pad 3, and the bottom edge of the steamer is placed between two annular protrusions with different diameters. The design of the annular protrusions facilitates the sealing and rapid positioning of the bottom edge of the steamer.

[0038] Example 5

[0039] like Figure 6 As shown, the components and their connection relationships included in this embodiment are basically the same as those in Embodiment 2, except that the steaming tray body 1 includes an outer ring body 12, a middle ring connecting body 13 and an inner ring body 14, the middle ring connecting body 13 is in an inverted cone shape, the upper end of the middle ring connecting body 13 is connected to the outer contour of the inner ring body 14, and the lower end of the middle ring connecting body 13 is connected to the inner contour of the outer ring body 12; the lower ring rubber pad 2 is connected to the lower surface of the outer ring body 12, and the upper ring rubber pad 3 is connected to the upper surface of the inner ring body 14; the hole in the middle of the inner ring body 14 is a vent. The lower ring rubber pad 2 of the outer ring body 12 contacts the pot mouth of the electric rice cooker or other pot body, the steamer is placed on the upper ring rubber pad 3 of the inner ring body 14, and the water vapor steams the dishes in the steamer through the vent of the inner ring body 14; through the structural design of the outer ring body 12, the middle ring connecting body 13 and the inner ring body 14, another implementation method of the steaming tray body 1 is realized, and the steaming tray body is diversified.

[0040] Specifically, the outer contour of the lower annular rubber pad 2 is provided with a lower return bend outer flange 21, which is fitted and connected to the upper surface of the outer contour of the outer annular body 12, and the lower annular rubber pad 2 and the lower return bend outer flange 21 wrap the outer contour of the outer annular body 12 therein; the inner contour of the lower annular rubber pad 2 is provided with a lower return bend inner flange 22, which is fitted and connected to the middle annular connector 13 by a radial cone.

The design of the lower bend outer flange 21, the lower bend inner flange 22, the upper bend outer flange 31 and the upper bend inner flange 32 can protect the exposed edges after the outer annular body 12, the middle annular connector 13 and the inner annular body 14 are connected, avoiding damage caused by collision between the steaming tray body 1 and foreign objects, and further ensuring the sealing performance when in contact with the spherical pot.

[0041] Of course, the multifunctional steaming tray of this embodiment can also be turned 180° for use. Figure 7 As shown, this embodiment is aimed at the situation that the rice cooker or other pot body has a small pot mouth and the bottom edge of the steamer is large. The water vapor generated by the smaller rice cooker or other pot body can also steam the dishes in the large-sized steamer, thereby improving practicality.

[0042] Example 6

[0043] A multifunctional steaming grid system, using any multifunctional steaming grid of embodiments 1 to 6, comprises a steam generating pot body 6 and a steamer 7, wherein a lower annular rubber pad 2 connected to the lower surface of the steam generating pot body 1 is placed on the steam generating pot body 6, and the water vapor in the steam generating pot body 6 is sealed by the lower annular rubber pad 2 contacting the inner surface of the steam generating pot body 6 or the edge of the pot mouth; the steamer 7 is placed on the upper surface of the steaming grid body 1. The steamer is a steamer, a steamer, or other steaming utensil. The aforementioned multifunctional steaming grid is applied to the multifunctional steaming grid system, thereby increasing the application scope of the multifunctional steaming grid. Figure 8 As shown, the multifunctional steaming grid system is a combination of a steam generating pot body 6, a steaming device 7 and the steaming grid in Example 6. The specific components of the steaming grid and their connection methods as well as the corresponding technical effects have been described in the previous text, so they will not be repeated here. Of course, the steam generating pot body 6 and the steaming device 7 can also be combined with any multifunctional steaming grid protected by this solution to achieve a steaming grid system with good technical effects.
