[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0050] The existing electric steamer, including steam base and steamer assembly, usually the steamer assembly and the steam base are matched by step surface, so as to limit the steamer assembly on the steam base, avoiding its movement along the horizontal direction relative to the steam base. Some existing steamer assemblies are mainly formed by plastic injection molding or hardware material stretching molding, no matter what material is used, when using, since the water amount in the steam base is invisible, when adding water in the middle, the whole steamer assembly needs to be taken down along the height direction, which is easy to be scalded by steam, and the condensed water on the steamer will also scatter on the table, which is very inconvenient.

[0051] In order to solve the above problems, as shown in Figures 1 to 22 The present application provides an electric steamer, so as to facilitate the user to add water into the steam base.

[0052] As shown in Figure 3 and Figure 5As shown, specifically, the electric steamer comprises a steam base 10 and a steaming rack assembly 20, the steam base 10 has a supporting top surface 121, the steam base 10 comprises a heating base 11, an inner pot 12 arranged on the heating base 11, and a heating assembly 13 arranged below the inner pot 12, the steaming rack assembly 20 comprises a steaming rack 21 arranged on the inner pot 12, the steaming rack 21 is provided with a supporting area, a supporting area arranged around the periphery of the supporting area, and a ring-shaped groove 215 connected between the supporting area and the supporting area, the side of the supporting area facing the steam base 10 is a matching surface 211, the side of the ring-shaped groove 215 facing the steam base 10 is a sliding surface 212, the sliding surface 212 is lower than the matching surface 211, a transition section 213 is arranged between the matching surface 211 and the sliding surface 212, the transition section 213 is a slope, the steaming rack 21 can slide relative to the supporting top surface 121, and has a working state and a sliding state, in the working state, the matching surface 211 is overlapped on the supporting top surface 121, in the sliding state, the matching surface 211 and the sliding surface 212 are jointly overlapped on the supporting top surface 121.

[0053] Wherein, the supporting top surface 121 can be the top surface of the heating base 11, or the top surface of the inner pot 12. For the convenience of description, the following takes the supporting top surface 121 as the top surface of the inner pot 12 as an example for description. When the steaming rack assembly 20 is arranged on the inner pot 12, the upward-facing side of the steaming rack 21 is the front surface, that is, the side of the steaming rack 21 away from the steam base 10 is the front surface; the downward-facing side of the steaming rack 21 is the back surface, that is, the side of the steaming rack 21 facing the steam base 10 is the back surface. Moreover, the inner pot 12 has a steam cavity 122.

[0054] It should be noted that, in the working state, the matching surface 211 of the steaming rack 21 can be overlapped on the supporting top surface 121, so that the steaming rack assembly 20 is stably arranged on the steam base 10 through the matching surface 211, the steaming rack assembly 20 completely covers the steam base 10, the internal structure of the steam base 10 is not exposed, avoiding the steam in the steam cavity 122 of the inner pot 12 from leaking; in the sliding state, the matching surface 211 and the sliding surface 212 can be jointly overlapped on the supporting top surface 121, so that the steaming rack assembly 20 is stably arranged on the steam base 10 through the matching surface 211 and the sliding surface 212, and the steaming rack assembly 20 is partially misaligned with the steam base 10, so that the steam cavity 122 of the inner pot 12 is partially exposed.

[0055] The electric steamer with slidable water adding function provided by the embodiment of the utility model, the slippage surface 212 is lower than the matching surface 211, so that the slippage surface 212, the transition section 213 and the matching surface 211 can form a step structure which limits the steamer rack assembly 20, under the action of no external force, the steamer rack assembly 20 can be stably erected on the steam base 10 through the matching surface 211, the heating assembly 13 can heat the water in the steam cavity 122 and generate steam to heat the food placed on the steamer 21 through the steam; when it is needed to observe the water level in the steam cavity 122 or add water into the steam cavity 122, the user can control the steamer rack assembly 20 to slide relative to the steam base 10 to the sliding state, the user can observe the water level in the steam cavity 122 or add water into the steam cavity 122 through the part of the steamer rack assembly 20 which is dislocated with the steam base 10, and the transition section 213 enables the slippage surface 212 and the matching surface 211 to be smoothly connected, so that the user controls the steamer rack assembly 20 to slide relative to the steam base 10, and the user operation is more smooth; after the operation is completed, the steamer rack assembly 20 is controlled to slide reversely relative to the steam base 10 to the working state, so that the steamer rack assembly 20 is overlapped on the support top surface 121 through the matching surface 211 again. In this way, when the water level in the steam cavity 122 is observed or water is added into the steam cavity 122, the steamer rack assembly 20 does not need to be taken down along the height direction, so that the user can be prevented from being scalded by the high-temperature steam in the process of taking down the steamer rack assembly 20, and the condensed water on the steamer rack assembly 20 can also be prevented from scattering on the table top, so as to facilitate the user operation. Moreover, the electric steamer with slidable water adding function does not need to change the shape of the inner pot 12, and can be suitable for the inner pot 12 made of any material.

[0056] As Figure 4 shown, the steamer 21 is provided with a plurality of steam holes 217, and the steam in the steam cavity 122 can flow upward through the steam holes 217 to heat the food placed on the steamer 21. The steamer 21 further comprises a plurality of reinforcing ribs 219 arranged at intervals, and the plurality of steam holes 217 are arranged at intervals between the reinforcing ribs 219. The reinforcing ribs 219 can improve the strength of the steamer 21 itself, and the steam holes 217 arranged between the reinforcing ribs 219 can also prevent the steamer 21 from being locally bent and deformed or even broken due to too many steam holes 217 at the position, so as to further improve the strength and reliability of the steamer 21.

[0057] As Figure 10 and Figure 21As shown, in an embodiment, the steamer rack 21 is in a square shape, for example, a rectangular or a square. For ease of description, the following is described by taking the steamer rack 21 as a rectangle, in which the first side edge 2181 is the long side of the rectangular steamer rack 21, and the second side edge 2183 is the short side of the rectangular steamer rack 21, i.e., the length of the first side edge 2181 is greater than the length of the second side edge 2183. Specifically, the steamer rack 21 has a first center line a perpendicular to the width direction (the Y-axis direction shown in the figure), two first side edges 2181 oppositely arranged on both sides of the first center line a, and two second side edges 2183 oppositely arranged on both sides of the second center line d perpendicular to the length direction (the X-axis direction shown in the figure). The first side edge 2181 and the second side edge 2183 form the square steamer rack 21. Of course, in other embodiments, the steamer rack 21 can also be in other shapes such as a polygon, a circle, an ellipse, etc., as long as the steamer rack assembly 20 can slide relative to the steam base 10, which is not specifically limited in the embodiments of the present application.

[0058] As shown, Figures 3 to 4 The steamer rack assembly 20 further includes a handle 22 arranged on the second side edge 2183. A user can take or place the steamer rack assembly 20 through the handle 22, and can also control the steamer rack assembly 20 to slide relative to the steam base 10 through the handle 22, so as to facilitate user operation. The handle 22 can be made of a material with a low thermal conductivity, for example, plastic, silicone rubber, etc., to prevent the user from being scalded. Specifically, the second side edge 2183 of the steamer rack 21 is provided with a handle mounting portion 2182 for mounting the handle 22. The handle 22 and the handle mounting portion 2182 are arranged in a split structure, which can facilitate the processing of the steamer rack 21. The number of handles 22 can be two, and the two handles 22 are arranged on the two second side edges 2183, respectively. Of course, the number of handles 22 can also be one, three, four or more according to needs, as long as the user can control the steamer rack assembly 20 to slide relative to the steam base 10 through the handle 22.

[0059] As shown, Figures 2 to 3As shown, in one embodiment, the sliding direction of the steam rack 21 relative to the supporting top surface 121 is along the width direction of the steam rack 21, that is, the steam rack assembly 20 can slide relative to the steam base 10 along the Y-axis direction. Specifically, the steam rack assembly 20 can be configured to slide relative to the steam base 10 in two directions along the Y-axis to a sliding state. Specifically, the user can hold the handles 22 on both sides and pull the steam rack assembly 20 to slide open relative to the steam base 10 along the -Y-axis direction, and push the steam rack assembly 20 to slide back to its original position relative to the steam base 10 along the +Y-axis direction; alternatively, the user can hold the handles 22 on both sides and push the steam rack assembly 20 to slide open relative to the steam base 10 along the +Y-axis direction, and pull the steam rack assembly 20 to slide back to its original position relative to the steam base 10 along the -Y-axis direction. Alternatively, the steam rack assembly 20 can be configured to slide only relative to the steam base 10 in a single direction along the Y-axis to a sliding state. Thus, the structure of the steam rack 21 is simple, and the stability of the steam rack assembly 20 in both the working and sliding states can be guaranteed.

[0060] like Figure 18 As shown, in another embodiment, the sliding direction of the steam rack 21 relative to the supporting top surface 121 is along the length direction of the steam rack 21, that is, the steam rack assembly 20 can slide relative to the steam base 10 along the X-axis direction. Specifically, the steam rack assembly 20 can be configured to slide in two directions along the X-axis relative to the steam base 10 to a sliding state. Specifically, the user can hold the handle 22 facing the -X-axis direction and pull the steam rack assembly 20 to slide open relative to the steam base 10 along the -X-axis direction, and then push the steam rack assembly 20 to slide back to its original position relative to the steam base 10 along the +X-axis direction; alternatively, the user can hold the handle 22 facing the +X-axis direction and pull the steam rack assembly 20 to slide open relative to the steam base 10 along the +X-axis direction, and then push the steam rack assembly 20 to slide back to its original position relative to the steam base 10 along the -X-axis direction. Alternatively, the steam rack assembly 20 can also be configured to slide in only one direction along the X-axis relative to the steam base 10 to a sliding state.

[0061] Furthermore, when the steam rack assembly 20 can slide relative to the steam base 10 in two directions along the X-axis to the sliding state, the lowest point of the handle 22 is higher than the mating surface 211. Thus, when the user holds one handle 22 and pulls the steam rack assembly 20 relative to the steam base 10 to the sliding state, the other handle 22 will not contact or interfere with the supporting top surface 121, avoiding increased resistance and making the user's operation smoother.

[0062] like Figures 14 to 16As shown, the height difference H1 between the matching surface 211 and the sliding surface 212 satisfies: 0.5mm≤H1≤5mm. The height difference H1 can be any value within the range of 0.5mm≤H1≤5mm, such as 0.5mm, 0.6mm, 1mm, 2mm, 5mm, etc. The height difference H1≥0.5mm can ensure the limiting effect of the step structure formed between the sliding surface 212, the transition section 213 and the matching surface 211 on the steamer assembly 20, preventing the steamer assembly 20 from deviating relative to the steam base 10, and ensuring that the steamer assembly 20 can be stably erected on the steam base 10. The height difference H1≤5mm can prevent the user from controlling the steamer assembly 20 to slide relative to the steam base 10 to the sliding state, so that when the sliding surface 212 cooperates with the support top surface 121, the inclination angle of the steamer assembly 20 is too large.

[0063] As shown in the embodiment, Figures 15 to 16 the inclined surface is a straight line, and the included angle a between the inclined surface and the horizontal plane satisfies: 5°≤a≤45°. In another embodiment, the inclined surface includes a circular arc section smoothly connected with the sliding surface 212, and the tangent angle a of the connection end of the circular arc section and the sliding surface 212 satisfies: 5°≤a≤45°. The circular arc section enables the transition section 213 and the sliding surface 212 to be smoothly connected, and the user's operation is more smooth. The included angle a can be any value within the range of 5°≤a≤45°, such as 5°, 10°, 40°, 45°, etc. The included angle a≥5° can ensure the limiting effect of the step structure formed between the sliding surface 212, the transition section 213 and the matching surface 211 on the steamer assembly 20, preventing the inclined surface from being too flat to cause the steamer assembly 20 to easily deviate on the steam base 10, thereby improving the stability of the steamer assembly 20 erected on the steam base 10. The included angle a≤45° can prevent the inclination angle of the inclined surface from being too large to cause the user to control the steamer assembly 20 to slide relative to the steam base 10 to have a large resistance, thereby making the user's operation more smooth. Preferably, the included angle a satisfies: 10°≤a≤25°, so that the steamer assembly 20 can be stably erected on the steam base 10, and the user can easily control the steamer assembly 20 to slide relative to the steam base 10.

[0064] As shown in the embodiment, Figures 4 to 5 the bottom wall of the annular groove 215 is provided with a backflow hole 2151. The annular groove 215 is a downwardly recessed structure, and the bottom wall of the annular groove 215 is lower than other areas on the steamer 21. The condensed water on the steamer 21 can flow into the annular groove 215, and drip into the steam cavity 122 through the backflow hole 2151, preventing the condensed water from accumulating on the steamer 21 to affect the cooking effect.

[0065] As shown in the embodiment, Figure 5As shown, the steam rack 21 further comprises a limiting portion 216, and a bottom surface of the limiting portion 216 is lower than the sliding surface 212. When the user controls the steam rack assembly 20 to slide relative to the steam base 10 to the sliding state, the limiting portion 216 will abut against the inner pot 12. The user can stop controlling the steam rack assembly 20 to continue to slide when the limiting portion 216 abuts against the inner pot 12, so as to avoid that the sliding distance of the steam rack assembly 20 relative to the steam base 10 is too large, and the overall center of gravity of the steam rack assembly 20 is located outside the steam base 10 to cause the steam rack assembly 20 to overturn, thereby being capable of limiting the sliding range of the steam rack assembly 20 relative to the steam base 10 by the limiting portion 216.

[0066] As shown in FIG. 1, the steam rack assembly 20 is capable of sliding relative to the steam base 10 along the Y-axis direction to the sliding state. Figures 10 to 11 As shown, when the steam rack assembly 20 is capable of sliding relative to the steam base 10 along the Y-axis direction to the sliding state, a distance L1 between any first side edge 2181 and the first middle line a and a distance L2 between the outer side of the limiting portion 216 close to the first side edge 2181 and the first middle line a satisfy: L1-L2≥20mm. In this way, it is ensured that the outer side of the limiting portion 216 is located on the side of the first middle line a close to the corresponding first side edge 2181, and the steam rack assembly 20 is further prevented from overturning due to the overall center of gravity of the steam rack assembly 20 being located outside the steam base 10. At the same time, it is also ensured that the distance between the first side edge 2181 and the outer side of the limiting portion 216 close to the first side edge 2181 is greater than or equal to 20mm, so that the space exposed by the steam cavity 122 is large enough in the sliding state, so as to facilitate the user to observe the water level in the steam cavity 122 or to add water into the steam cavity 122.

[0067] As shown in FIG. 1, the steam rack assembly 20 is capable of sliding relative to the steam base 10 along the Y-axis direction to the sliding state. Figure 10 As shown, when the steam rack assembly 20 is capable of sliding relative to the steam base 10 along the Y-axis direction to the sliding state, a distance L1 between any first side edge 2181 and the first middle line a and a distance L2 between the outer side of the limiting portion 216 close to the first side edge 2181 and the first middle line a satisfy: L1-L2≥20mm. In this way, it is ensured that the outer side of the limiting portion 216 is located on the side of the first middle line a close to the corresponding first side edge 2181, and the steam rack assembly 20 is further prevented from overturning due to the overall center of gravity of the steam rack assembly 20 being located outside the steam base 10. At the same time, it is also ensured that the distance between the first side edge 2181 and the outer side of the limiting portion 216 close to the first side edge 2181 is greater than or equal to 20mm, so that the space exposed by the steam cavity 122 is large enough in the sliding state, so as to facilitate the user to observe the water level in the steam cavity 122 or to add water into the steam cavity 122.

[0068] As shown in FIG. 1, the steam rack assembly 20 is capable of sliding relative to the steam base 10 along the Y-axis direction to the sliding state. Figure 11As shown, when the steam rack assembly 20 can slide relative to the steam base 10 along a single direction on the Y-axis to the sliding state, the outer side of the limiting portion 216 and the adjacent one of the first side edges 2181 form a sliding area, and the other first side edge 2181 forms a support area, the steam rack 21 is provided with a plurality of steam holes 217, and the plurality of steam holes 217 are arranged at intervals in the support area. The number of limiting portions 216 is at least one, for example, in the +Y-axis direction of the first middle line a, the distance between the first side edge 2181 and the outer side of the limiting portion 216 adjacent to the first side edge 2181 is greater than or equal to 20mm, the two second side edges 2183 and the first side edge 2181 in the +Y-axis direction, the straight line b form a sliding area, and the two second side edges 2183 and the first side edge 2181 in the -Y-axis direction, the straight line b form a support area. In this way, it can also be ensured that in the sliding state, the projection of the steam hole 217 on the steam base 10 is located in the steam cavity 122, preventing condensed water on the steam rack assembly 20 from dripping onto the table top through the steam hole 217.

[0069] Similarly, as shown in FIG. 6, when the steam rack assembly 20 can slide relative to the steam base 10 along the X-axis direction, the distance L3 between any second side edge 2183 and the second middle line d and the distance L4 between the outer side of the limiting portion 216 adjacent to the second side edge 2183 and the second middle line d satisfy: L3-L4≥20mm. Figures 21 to 22 As shown in FIG. 6, when the steam rack assembly 20 can slide relative to the steam base 10 along the X-axis direction, the distance L3 between any second side edge 2183 and the second middle line d and the distance L4 between the outer side of the limiting portion 216 adjacent to the second side edge 2183 and the second middle line d satisfy: L3-L4≥20mm.

[0070] Figure 21 As shown in FIG. 6, when the steam rack assembly 20 can slide relative to the steam base 10 along the X-axis direction, the distance L3 between any second side edge 2183 and the second middle line d and the distance L4 between the outer side of the limiting portion 216 adjacent to the second side edge 2183 and the second middle line d satisfy: L3-L4≥20mm.

[0071] As shown in FIG. 6, when the steam rack assembly 20 can slide relative to the steam base 10 along the X-axis direction, the distance L3 between any second side edge 2183 and the second middle line d and the distance L4 between the outer side of the limiting portion 216 adjacent to the second side edge 2183 and the second middle line d satisfy: L3-L4≥20mm. Figure 22 ​As shown, when the steam rack assembly 20 can slide to a sliding state relative to the steam base 10 in a single direction along the X-axis, the number of limiting parts 216 is at least one. Taking the steam rack assembly 20 being able to slide to a sliding state relative to the steam base 10 in the -X-axis direction as an example, in the -X-axis direction of the second centerline d, the distance between the second side 2183 and the outer side of the limiting part 216 near the second side 2183 is greater than or equal to 20mm. The two first sides 2181, the second side 2183 in the -X-axis direction, and the straight line e form a sliding area, and the two first sides 2181, the second side 2183 in the +X-axis direction, and the straight line e form a support area.

[0072] like Figures 4 to 6 As shown, in one embodiment, the limiting part 216 is located in the supporting area. The supporting area has a large space to facilitate the processing of the limiting part 216. The limiting part 216 may include a raised groove formed by recessing downwards from the bottom wall of the steaming rack 21, i.e., a groove structure is formed on the front side of the steaming rack 21. The limiting part 216 can be processed by stamping, which is simple, convenient, and low-cost. Furthermore, to prevent condensate on the steaming rack 21 from flowing into the groove structure and accumulating there, thus affecting the cooking effect, the limiting part 216 is provided with a first through hole 2161 penetrating the steaming rack 21. This allows condensate flowing into the groove structure to drip into the steam chamber 122 through the first through hole 2161.

[0073] Alternatively, the limiting part 216 may include a protrusion on the lower surface of the bottom wall of the steaming rack 21, that is, a groove structure is not formed on the front side of the steaming rack 21. This avoids the bottom of the groove structure formed on the front side of the steaming rack 21 being lower than other areas on the support area, which would cause condensate on the support area to flow into the groove structure and accumulate there, thus affecting the cooking effect.

[0074] like Figures 4 to 5As shown, in an embodiment, the limiting portion 216 is arranged on the side edge parallel to the sliding direction of the annular groove 215. Thus, the limiting portion 216 can avoid occupying too much space on the bearing area, so that there is enough area on the bearing area to process the steam hole 217, the egg steaming groove 214, the reinforcing rib 219 and other structures. Among them, the limiting portion 216 can include a protruding groove recessed downward from the bottom wall of the steaming rack 21. Specifically, the annular groove 215 includes a first return groove 2152 and a second return groove 2153 that are in communication with each other, and the second return groove 2153 is a protruding groove. The first return groove 2152 and the second return groove 2153 can be processed by stamping forming, which is simple in processing method and low in cost. In addition, the return hole 2151 can be arranged on the bottom wall of the second return groove 2153. The condensed water on the steaming rack 21 can first flow into the first return groove 2152, and then the condensed water in the first return groove 2152 flows into the second return groove 2153, and finally the condensed water in the second return groove 2153 drips into the steam cavity 122 through the return hole 2151. Thus, the condensed water on the steaming rack 21 can be guided to drip into the steam cavity 122 along the first return groove 2152, the second return groove 2153 and the return hole 2151.

[0075] As shown, Figure 11 and Figure 20 The number of second return grooves 2153 can be one, two or more. Specifically, when the steaming rack assembly 20 can slide relative to the steam base 10 along the Y-axis direction, and the number of second return grooves 2153 is two, the two second return grooves 2153 are arranged close to the two second side edges 2183 respectively, so as to further prevent the steaming rack assembly 20 from sliding relative to the steam base 10 along the X-axis direction. Similarly, when the steaming rack assembly 20 can slide relative to the steam base 10 along the X-axis direction, and the number of second return grooves 2153 is two, the two second return grooves 2153 are arranged close to the two first side edges 2181 respectively, so as to further prevent the steaming rack assembly 20 from sliding relative to the steam base 10 along the Y-axis direction, and further improve the stability and reliability of the steaming rack assembly 20 on the steam base 10.

[0076] Alternatively, as shown, Figures 8 to 9As shown, to avoid the second reflux groove 2153 being too deep, resulting in an excessively low moment of inertia at that section and making it prone to bending deformation or even breakage, and to improve the manufacturability of the steam rack 21, the second reflux groove 2153 can be omitted. The limiting part 216 can also include a protrusion provided on the lower surface of the bottom wall of the steam rack 21, that is, the limiting part 216 is provided on the back side of the first reflux groove 2152. Furthermore, the limiting part 216 can be arranged corresponding to the reflux hole 2151 and is provided with a third through hole 2162 communicating with the reflux hole 2151. The condensate on the steam rack 21 can flow into the first reflux groove 2152, and the condensate in the first reflux groove 2152 drips into the steam chamber 122 through the reflux hole 2151 and the third through hole 2162. When the user controls the steam rack assembly 20 to slide relative to the steam base 10 to the sliding state, the limiting part 216 can limit the sliding range of the steam rack assembly 20 relative to the steam base 10, so as to avoid the steam rack assembly 20 sliding too far relative to the steam base 10, causing the overall center of gravity of the steam rack assembly 20 to be located outside the steam base 10 and causing it to tip over.

[0077] like Figures 8 to 9 As shown, the limiting part 216 includes a limiting section 2163 and an installation section 2164. The installation section 2164 is connected to the steam rack 21, so that the limiting section 2163 fits against the back of the steam rack 21. Specifically, the steam rack 21 has an installation hole, and the installation section 2164 is inserted into the installation hole. The limiting part 216 can be a silicone part to facilitate production and assembly, and it can also play a buffering role when the limiting part 216 abuts against the inner pot 12 to protect the steam rack 21 and the inner pot 12.

[0078] like Figures 4 to 5 As shown, the steaming rack 21 is also equipped with an egg steaming tray 214, and the bottom wall of the egg steaming tray 214 has a second through hole 2141. The egg steaming tray 214 is used to place the egg and prevent it from rolling on the steaming rack 21. Since the egg steaming tray 214 has a downwardly recessed structure, its bottom wall is lower than other areas on the steaming rack 21. Condensation on the steaming rack 21 may flow into the egg steaming tray 214. The second through hole 2141 allows the condensation flowing into the egg steaming tray 214 to drip into the steam chamber 122, preventing condensation from accumulating in the egg steaming tray 214 and affecting the cooking effect. The number of egg steaming trays 214 can be one, two, or more, with multiple egg steaming trays 214 arranged at intervals.

[0079] like Figure 7As shown, in one embodiment, the bottom surface of the at least one egg steaming groove 214 is lower than the sliding surface 212 to form the limiting portion 216, because setting the limiting portion 216 alone will form a groove structure on the front surface of the steaming rack 21, which is easy to deposit dirt and cause the steaming rack 21 to be difficult to clean. When the user controls the steaming rack assembly 20 to slide relative to the steam base 10 to the sliding state, the limiting portion 216 formed on the back surface of the egg steaming groove 214 can limit the sliding range of the steaming rack assembly 20 relative to the steam base 10, so as to avoid the distance of the steaming rack assembly 20 sliding relative to the steam base 10 being too large, causing the overall center of gravity of the steaming rack assembly 20 to be located outside the steam base 10 and causing the steaming rack assembly 20 to overturn.

[0080] As shown in Figure 14 and Figure 17 , the height difference H2 between the bottom surface of the limiting portion 216 and the sliding surface 212 satisfies: 2mm≤H2≤6mm. Wherein, the height difference H2 can be 2mm, 3mm, 4mm, 5mm, 6mm, etc. within the range of 2mm≤H1≤6mm, and preferably H2>H1. The height difference H2≥2mm can ensure the limiting effect of the limiting portion 216 on the steaming rack assembly 20, prevent the steaming rack assembly 20 from sliding relative to the steam base 10 to the overall center of gravity being located outside the steam base 10 and causing the steaming rack assembly 20 to overturn, and ensure the stability of the steaming rack assembly 20 in the sliding state. The height difference H2≤6mm can prevent the overall thickness of the steaming rack assembly 20 from being too large and affecting the normal use of the steaming rack assembly 20.

[0081] As shown in Figure 1 , the steam pot with slidable water adding function can further include a cage 30 and a cover 40. When only one layer of steaming rack assembly 20 needs to be arranged, the cover 40 can be arranged on the steaming rack assembly 20; when multiple layers of steaming rack assembly 20 need to be arranged, the cage 30 can be arranged on the bottom layer of steaming rack assembly 20, and the second layer of steaming rack assembly 20 can be arranged on the cage 30, and so on, and finally the cover 40 is arranged on the top layer of steaming rack assembly 20.

[0082] As shown in Figure 15As shown, when the cage body 30 or the cover 40 is mounted on the steam rack assembly 20, steam overflowing from the gap between the steam rack 21 and the cage body 30 or the cover 40 may form condensation at the edge of the steam rack 21. Therefore, the steam rack 21 includes detachable or integrated side walls and a bottom wall, with the sliding surface 212 and the mating surface 211 both located on the bottom wall of the steam rack 21. The integrated design ensures the connection strength between the side wall and the bottom wall and is simple and convenient to manufacture. The side wall includes a folded edge 2184 that bends upward from the edge of the bottom wall. The upward bend of the folded edge 2184 prevents condensation from dripping from the edge of the steam rack 21 onto the work surface. The cross-section of the folded edge 2184 can be an L-shaped structure as shown in the figure or a straight structure, as long as the highest point of the folded edge 2184 is higher than other areas of the steam rack 21 within the folded edge 2184. That is, the height difference H3 between the highest point of the folded edge 2184 and other areas of the steam rack 21 within the folded edge 2184 satisfies: H3 > 0 mm.

[0083] like Figure 16 As shown, the sidewall also includes a flange 2185 that bends downwards from the edge of the folded edge 2184. The flange 2185 can improve the strength of the edge of the steam rack 21, and since the steam rack 21 is mostly made of sheet metal, and the edges of sheet metal are relatively sharp and may have burrs, the flange 2185 can also prevent the user's hand from being cut. In addition, the lowest point of the flange 2185 is higher than the mating surface 211, that is, the height difference H4 between the lowest point of the flange 2185 and the mating surface 211 satisfies: H4 > 0 mm, preferably H4 > 0.1 mm. In this way, when the user controls the steam rack assembly 20 to slide relative to the steam base 10 to the sliding state, the flange 2185 will not contact or interfere with the supporting top surface 121, avoiding increased resistance and making the user's operation smoother. The cross-section of the flange 2185 can be a straight structure as shown in the figure, or it can be C-shaped, rolled, or other shapes.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
