Description

Technical Field

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

[0002] Steamers have a long history in Chinese food culture. Steamers are usually used with steaming racks, and the height of the steaming racks is fixed. When the height of the food is small, it is difficult to fully utilize the space of the steaming racks. When the height of the food is large, the food exceeds the steaming racks and the lid cannot be properly covered. It can be seen that the height of the steaming racks of existing steamers cannot be adjusted, resulting in a mismatch between the space for holding food and the height of the food, which brings great inconvenience to users. Utility Model Content

[0003] The present application provides a steamer, which can rearrange the steaming grid space as needed, thereby adjusting the accommodating space for holding food and improving the convenience of use for users.

[0004] The present application provides a steamer, which comprises:

[0005] A pot body, wherein a first support portion and a second support portion are provided at the mouth of the pot body, wherein the second support portion is located above the first support portion and is further away from the axis of the pot body than the first support portion;

[0020] Optionally, at the edge of the second supporting portion, the third supporting portion is aligned with the first supporting portion, reducing the size variation of the components of the steamer and improving the overall size consistency of the steamer, so that the components form as similar a matching effect as possible when they cooperate with each other.

[0021] Optionally, the second overlapping portion is configured as a curling structure, which can not only form a smooth and flat edge to prevent the edge of the steaming grid from scratching a user, but also improve the structural strength of the steaming grid to prevent the steaming grid from being deformed or otherwise damaged.

[0022] Optionally, the steamer further comprises a first steaming grate, and when the steaming grid is inverted, the first steaming grate overlaps and cooperates with the third supporting portion, which can provide the steaming grate with supporting force along the axial direction of the steaming grid and provide the steaming grate with radial limiting effect around the edge of the steaming grid.

[0023] Optionally, the steamer further comprises a first steaming grate;

[0024] When the steaming rack is placed upright, the first steaming rack overlaps and cooperates with the first supporting portion, thereby further dividing the accommodation space between the steaming rack and the pot body;

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0063] like Figure 1-Figure 9 As shown, an embodiment of the present application provides a steamer, which includes a pot body 1, a steaming rack 2 and a pot cover 3. The pot body 1 is configured as a cavity-shaped structure capable of containing food, the steaming rack 2 is stacked and arranged above the pot body 1, and the pot cover 3 is stacked and arranged above the steaming rack 2, so that a holding space for containing food is formed between the steaming rack 2 and the pot cover 3 and between the pot body 1 and the steaming rack 2; it can be understood that the steaming rack 2 can also be removed, and the pot cover 3 can be directly stacked and arranged above the pot body 1. The mouth of the pot body 1 is provided with a first support portion 11 and a second support portion 12, the second support portion 12 is located above the first support portion 11, and the second support portion 12 is farther away from the axis of the pot body 1 than the first support portion 11; the steaming rack 2 includes a first end portion 21 and a second end portion 22 that are arranged opposite to each other, the first end portion 21 is provided with a perforated plate 24, the second end portion 22 is open, and the radial dimension of the second end portion 22 is greater than the radial dimension of the first end portion 21; the steaming space can be reorganized as needed by simply placing the steaming rack 2 upright or upside down, the operation is simple, and the accommodation space for holding food can be effectively adjusted, thereby improving the convenience of use for users.

[0064] Specifically, when the steaming rack 2 is placed upright, the second end portion 22 overlaps with the second support portion 12, and the pot cover 3 overlaps with the first end portion 21; on the one hand, the perforated plate 24 is located above the steaming rack 2, thereby forming a smaller accommodating space between the steaming rack 2 and the pot cover 3, and a larger accommodating space between the pot body 1 and the steaming rack 2; on the other hand, the steaming rack 2 is overlapped with the second support portion 12 with a higher height, and the steaming rack 2 is lifted as a whole, thereby further increasing the accommodating space between the pot body 1 and the steaming rack 2, so that larger volume of food can be steamed and cooked. When the steaming rack 2 is turned upside down, the first end 21 overlaps with the first branch, and the pot cover 3 overlaps with the second end 22; on the one hand, the perforated plate 24 is located below the steaming rack 2, thereby forming a larger accommodating space between the steaming rack 2 and the pot cover 3, and a smaller accommodating space between the pot body 1 and the steaming rack 2; on the other hand, the steaming rack 2 is overlapped with the first supporting portion 11 with a lower height, so that the steaming rack 2 sinks as a whole, thereby further reducing the accommodating space between the pot body 1 and the steaming rack 2, so as to improve the space utilization rate when steaming small-volume food; in addition, the overall sinking of the steaming rack 2 can also lower the center of gravity of the steaming rack 2, improve the stability of the placement of the steaming rack 2, and prevent accidents such as tipping over when a large amount of food is placed on the steaming rack 2.

[0065] like Figure 4-Figure 9 As shown, the first support portion 11 is configured as an L-shaped structure, and the second support portion 12 is configured as an L-shaped structure. The opening direction of the L-shaped structure is located on the side close to the axis of the pot body 1, so that the first support portion 11 and the second support portion 12 can provide both the supporting force along the axial direction of the pot body 1 and the radial limiting effect around the edge of the pot body 1. Specifically, the L-shaped structure includes an axial support section and a radial limiting section; the axial support section is arranged horizontally, so that the supporting force along the axial direction of the pot body 1 can be provided; the radial limiting section is connected to the outer side of the axial support section, and the radial limiting section is arranged in the vertical direction, so that the radial limiting effect around the pot body 1 can be provided. It can be understood that the first support portion 11 and the second support portion 12 can also be configured as other structures such as flanges, as long as they can provide a supporting effect.

[0066] Furthermore, a curling structure can be provided on the side of the second support portion 12 away from the axis of the pot body 1, which can not only form a smooth and flat edge to prevent the edge of the pot body 1 from scratching the user, but also improve the structural strength of the pot body 1 to prevent the pot body 1 from deformation and other damage.

[0067] The steaming grid 2 further includes a main body 23, which is arranged in a ring shape. The first end 21 and the second end 22 are connected to each other through the main body 23, so that the steaming grid 2 forms a cavity-like structure with a certain height. The first end 21 and the main body 23 can be integrally formed, or they can be connected to each other by welding or riveting. Similarly, the second end 22 and the main body 23 can be integrally formed, or they can be connected to each other by welding or riveting. The orifice plate 24 is provided with a through hole that allows steam to pass through. The orifice plate 24 can be connected to the first end 21 by an integrally formed or welded non-detachable manner, or the orifice plate 24 can be connected to the first end 21 by a snap fit or other detachable manner.

[0068] Further, the first end portion 21 includes an extension portion 211, a first overlap portion 212 and a limiting portion 213. The extension portion 211 is connected to the main body portion 23 and extends in a direction away from the second end portion 22; the first overlap portion 212 is connected to one end of the extension portion 211 away from the main body portion 23 and extends in a direction close to the axis of the steaming rack 2. The first overlap portion 212 is used to overlap with the pot cover 3 or the first support portion 11, thereby forming a larger overlap area at the first end portion 21, thereby increasing the stability of stacking; the limiting portion 213 is connected to one side of the first overlap portion 212 close to the axis of the steaming rack 2, and extends in a direction away from the second end portion 22, so as to extend into the inner side of the pot body 1 or the inner side of the pot cover 3, thereby forming a radial limit for the pot body 1 or the pot cover 3.

[0069] Specifically, when the steaming rack 2 is placed upright, the first end portion 21 faces upward, and the limiting portion 213 extends into the inner side of the pot cover 3, thereby forming a radial limit between the pot cover 3 and the steaming rack 2, reducing the radial movement amplitude of the pot cover 3, and improving the placement stability of the pot cover 3; when the steaming rack 2 is placed upside down, the first end portion 21 faces downward, and the limiting portion 213 extends into the inner side of the pot body 1, thereby forming a radial limit between the steaming rack 2 and the pot body 1, reducing the radial movement amplitude of the steaming rack 2, and improving the placement stability of the steaming rack 2.

[0070] Furthermore, along the direction away from the second end 22, the radial dimension of at least one section of the extension portion 211 gradually increases. For example, the extension portion 211 is configured as a flared conical structure, which can increase the overlap area of ​​the first overlap portion 212 without changing the size of the main body 23, thereby increasing the stability of stacking, and can make the size change continuously and smoothly to avoid stress concentration caused by structural mutation. It can be understood that the extension portion 211 can also adopt a stepped structure to increase the radial dimension.

[0071] Furthermore, the orifice plate 24 is integrally formed at the end of the limiting portion 213 away from the second end portion 22, which can not only improve the connection strength of the orifice plate 24 and prevent the orifice plate 24 from being damaged such as loosening or falling off, but also form smooth and flat bearing areas on both sides of the orifice plate 24, thereby preventing the orifice plate 24 from scratching the surface of the food.

[0072] Further, the second end portion 22 includes a third support portion 221 and a second overlap portion 222. The third support portion 221 is connected to the main body portion 23, and the third support portion 221 is further away from the axis of the steaming tray 2 relative to the main body portion 23, and is used to form an overlap fit with the pot cover 3, that is, to ensure that when the steaming tray 2 is placed upside down, it can provide reliable support and limit the pot cover 3, thereby improving the stability of the placement of the pot cover 3; the second overlap portion 222 is connected to one end of the third support portion 221 away from the main body portion 23, and the second overlap portion 222 is further away from the axis of the steaming tray 2 relative to the third support portion 221, and is used to overlap with the second support portion 12, that is, the local radial dimension is increased by the second overlap portion 222, so that it can form an overlap fit with the second support portion 12, and ensure that when the steaming tray 2 is placed upright, it can be stably placed on the second support portion 12.

[0073] Furthermore, the third support portion 221 is configured as the L-shaped structure, and the opening direction of the L-shaped structure is located on a side close to the axis of the steaming tray 2, so that the third support portion 221 can provide both axial support force along the steaming tray 2 and radial limiting effect around the edge of the steaming tray 2.

[0074] Furthermore, at the edge of the second support portion 12, the third support portion 221 is aligned with the first support portion 11, that is, the radial limiting sections of the third support portion 221 and the first support portion 11 are aligned with each other, thereby reducing the size variations of the components of the steamer and improving the consistency of the overall size of the steamer, so that the components can form as similar a matching effect as possible when they cooperate with each other.

[0075] Furthermore, the second overlapping portion 222 is configured as a curling structure, which can form a smooth and flat edge to prevent the edge of the steaming tray 2 from scratching the user, and can also improve the structural strength of the steaming tray 2 to prevent the steaming tray 2 from deformation or other damage.

[0076] Furthermore, the bottom end of the pot cover 3 is provided with a third overlap portion 31 and a stop portion 32. The third overlap portion 31 is arranged on the inner side of the pot cover 3, and the third overlap portion 31 is arranged as an annular structure extending along the radial direction of the pot cover 3, and is used to overlap and cooperate with the first end portion 21 or the second end portion 22 to increase the overlap and cooperation area, thereby improving the stability of the pot cover 3 when stacked; the stop portion 32 is connected to the side of the third overlap portion 31 close to the axis of the pot cover 3, and the stop portion 32 protrudes above the third overlap portion 31, so that a liquid storage tank is formed on the outer side of the stop portion 32 to prevent water drops sliding along the surface of the pot cover 3 from affecting the cooking effect of food; the stop portion 32 can be arranged as a curling structure to form a smooth edge and increase the structural strength of the pot cover 3.

[0077] Furthermore, the steamer provided in the embodiment of the present application also includes a first steaming grate 4, which is located at the mouth of the steaming rack 2. The first steaming grate 4 further divides the storage space on the mouth side of the steaming rack 2, thereby meeting various usage requirements; when the steaming rack 2 is placed upright, the first steaming grate 4 overlaps with the first supporting portion 11, that is, the steaming rack 2 is placed at the mouth of the pot body 1, thereby further dividing the storage space between the steaming rack 2 and the pot body 1; when the steaming rack 2 is inverted, the first steaming grate 4 overlaps with the second end portion 22, that is, the steaming rack 2 is placed at the mouth of the steaming rack 2, thereby further dividing the storage space between the steaming rack 2 and the pot cover 3.

[0078] Furthermore, when the steaming grid 2 is turned upside down, the first steaming grate 4 overlaps and cooperates with the third supporting portion 221, which can provide the steaming grate with an axial supporting force along the steaming grid 2 and a radial limiting effect around the edge of the steaming grid 2.

[0079] Furthermore, the steamer provided in the embodiment of the present application also includes a second steaming grate 5, which is placed inside the pot body 1. For example, a convex rib 13 can be provided inside the pot body 1, and the second steaming grate 5 overlaps with the convex rib 13. The second steaming grate 5 further divides the accommodating space inside the pot body 1, thereby meeting various usage requirements.

[0080] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
