For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] Example 1 A preferred embodiment, such as Figure 1 As shown, an adjustable-height rice steamer 1 is described. In this embodiment, the rice steamer 1 is a single-door rice steamer 1. The inner cavity of the rice steamer 1 has a tray rack 2. The tray rack 2 adopts an independent design and can be placed into the inner cavity of the rice steamer 1 as a whole or taken out of the inner cavity of the rice steamer 1 as a whole.

[0026] Specifically, refer to Figure 2 and Figure 3 The tray rack 2 includes a supporting base 21, a fixed top support 22, and multiple supporting columns 23. The supporting base 21 and the fixed top support 22 are rectangular frames, and there are at least four supporting columns 23 connected to the four corners of the supporting base 21 and the fixed top support 22. Multiple placement trays 24 for placing rice steaming trays are movably connected to two supporting columns 23 on the same side. The connection method is through a connector 231 and a position adjustment ring 25 located on the supporting column 23. The position adjustment ring 25 is located below the placement tray 24. By fixing the position adjustment ring 25 to the connector 231, the position adjustment ring 25 supports the placement tray 24, thereby supporting the placement tray 24 on the supporting column 23. The height of the connection between the position adjustment ring 25 and the connector 231 determines the height of the placement tray 24, and thus the placement height of the rice steaming tray. Therefore, the height of the rice steaming tray, i.e., the layer height of the tray rack 2, can be adjusted by adjusting the connection between the position adjustment ring 25 and the connector 231.

[0027] Specifically, the following are some ways in which the connector 231 and the position adjusting ring 25 can be coupled: Method 1: Reference Figure 4The connector 231 is a threaded ring 232 extending from the top to the bottom of the support column 23. The position adjustment ring 25 is threadedly engaged with the threaded ring 232. By rotating the position adjustment ring 25, its height on the support column 23 can be changed. When adjusting the height of the tray rack 2, simply remove the tray rack 2 from the rice steamer 1, and then adjust the position adjustment rings 25 on each of the four support columns 23 as needed to complete the height adjustment of the placement tray 24. Since the position adjustment rings 25 on the four support columns 23 are adjusted individually, to ensure that the placement tray 24 is on the same horizontal plane after adjustment, a reference plane 233 extending along the axial direction of the support column 23 is formed on the outer peripheral wall of the threaded ring 232. The reference plane 233 has a height indication scale line 234. When rotating the position adjustment ring 25, it can be rotated to the same height, thereby ensuring that the placement tray 24 is horizontal.

[0028] Method 2: Reference Figure 5 Unlike the first method, the connector 231 consists of multiple threaded rings 232 spaced apart on the support column 23. The position adjustment ring 25 is threadedly engaged with the threaded rings 232. The spaced arrangement allows for preset layer height settings based on the characteristics of different ingredients. The preset method involves different spacing between the threaded rings 232. This provides a reference for adjusting the layer height and also allows for fine-tuning based on actual conditions. To facilitate accurate reading of the layer height and ensure that the placement tray 24 is on the same horizontal plane after fine-tuning, a layer height indicator scale 235 is provided on the outer peripheral wall of the support column 23 in the spaced area of ​​the threaded rings 232.

[0029] Method 3: Reference Figure 6 Unlike the threaded connection used in methods one and two, the connector 231 includes a displacement groove 236 extending from the top to the bottom of the support column 23. Rotation grooves 237, which communicate with the displacement groove 236, are spaced apart on the side of the displacement groove 236. A placement groove 238, lower in height than the rotation groove 237, is formed on the side of the rotation groove 237 facing away from the displacement groove 236. A connecting protrusion 239, which mates with the displacement groove 236, rotation groove 237, and placement groove 238, is formed on the inner side of the position adjustment ring 25. This configuration allows for direct preset of the floor height spacing via the rotation groove 237 and placement groove 238. When the floor height needs adjustment, the position adjustment ring 25 moves along the displacement groove 236. When it reaches the position of the rotation groove 237, it rotates towards the placement groove 238, causing the connecting protrusion 239 to move from the displacement groove 236 to the placement groove 238. Then, the position adjustment ring 25 is pulled down to allow the connecting protrusion 239 to enter the bottom of the placement groove 238. This setting method offers greater stability and makes height adjustment more convenient and faster.

[0030] Example 2 A preferred embodiment, such as Figure 9 As shown, the placement tray 24 has a tray insertion groove 241 that mates with the edge of the rice steaming tray. The end of the tray insertion groove 241 has a limiting block 242 that restricts the position of the rice steaming tray. The side of the limiting block 242 facing the rice steaming tray has a buffer slider 243 that slides along the tray insertion groove 241. A buffer spring 244 connects the buffer slider 243 and the limiting block 242. By using the limiting block 242, the insertion position of the rice steaming tray can be restricted, preventing the rice steaming tray from hitting the rear wall of the rice steamer during placement. The buffer spring 244 and the buffer slider 243 provide cushioning when the worker pushes the rice steaming tray, reducing the impact force on the limiting block 242 and extending the service life of the placement tray 24.

[0031] Example 3 A preferred embodiment, such as Figure 7 , Figure 8 As shown, the support base 21 and the fixed top support 22 have an insertion groove 211 that mates with the support column 23 and a fixing groove 212 that is perpendicular to the insertion groove 211. The end of the support column 23 has a fixing hole 217 that mates with the fixing groove 212, so that the support column 23 can be connected between the support base 21 and the fixed top support 22 by the cooperation of the fixing bolt 213, the fixing groove 212, and the fixing hole 217.

[0032] Specifically, an anti-rotation groove 214 is formed on the fixing groove 212 of the support base 21, and an anti-rotation protrusion 215 that mates with the anti-rotation groove 214 is formed on the bottom of the support column 23. During assembly, this facilitates the insertion of the support column 23 into the support base 21, and the engagement of the anti-rotation groove 214 and the anti-rotation protrusion 215 facilitates the positioning of the fixing hole 217 and the fixing bolt 213, and prevents rotation of the support column 23 after connection. This also allows for adjustment of the tray rack 2's layer height by rotating the position adjustment ring 25. Similarly, an anti-rotation protrusion 215 is formed on the fixing groove 212 of the fixed top support 22, and an anti-rotation groove 214 that mates with the anti-rotation protrusion 215 is formed on the top of the support column 23. This arrangement allows for the insertion or removal of the placement tray 24 by removing the fixed top support 22, thereby changing the number of layers in the tray rack 2. This allows for the rational setting of the tray rack 2's layer height and number of layers according to the different foods being steamed, improving the steam utilization efficiency in the rice steamer 1.

[0033] Furthermore, the fixing bolt 213 has a rotating handle 216, which makes it easy to directly tighten the fixing bolt 213 by rotating the handle 216.

[0034] Furthermore, the support base 21 and the rice steamer 1 are connected by a drawer slide rail to facilitate the removal of the tray rack 2.
