[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 this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the 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 the steam base and the steamer assembly, usually the steamer assembly and the steam base are matched by the stepped surface to be able 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 made, 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. In the related prior art, some electric steamers also use special-shaped inner pot, the inner pot is provided with a water adding structure protruding from the pot body, but this will lead to the complex structure of the inner pot, and there are many cleaning dead angles, and the special-shaped inner pot is usually a plastic inner pot, which is difficult to form for a stainless steel inner pot.

[0051] In order to solve the above problems, as shown in Figures 1 to 22 The utility model provides an electric steamer of slippable water adding, in order to facilitate user to add water in the steam base.

[0052] As shown in Figure 3 And Figure 5 As shown in the specific electric steamer of slippable water adding includes steam base 10, steamer assembly 20 and cover 40 from below to above setting successively, steam base 10 includes heating base 11, be located in the inner pot 12 of heating base 11 and be located in the heating assembly 13 under the inner pot 12, and steam base 10 has support top surface 121, steamer assembly 20 includes the steamer 21 of being located on the inner pot 12, and the steamer 21 is equipped with the support area of holding area, the annular groove 215 of being located in the periphery of holding area and being connected between holding area and support area, the side of support area towards steam base 10 is the matching surface 211, and the side of annular groove 215 towards steam base 10 is the slippage surface 212, and slippage surface 212 is lower than matching surface 211, and the steamer 21 can slide relative to support top surface 121 and has working state and sliding state, in working state, matching surface 211 overlaps on support top surface 121, and in sliding state, matching surface 211 and slippage surface 212 overlap on support top surface 121 together.

[0053] The support 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 support top surface 121 as the top surface of the inner pot 12 as an example for description. When the steamer assembly 20 is erected on the inner pot 12, the upward-facing surface of the steamer 21 is the front surface, that is, the surface of the steamer 21 facing away from the steam base 10 is the front surface; the downward-facing surface of the steamer 21 is the back surface, that is, the surface of the steamer 21 facing toward the steam base 10 is the back surface. In addition, 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 steamer 21 can be lapped on the support top surface 121, so that the steamer assembly 20 is stably erected on the steam base 10 through the matching surface 211, the steamer assembly 20 completely covers the steam base 10, the internal structure of the steam base 10 is not exposed, and leakage of steam in the steam cavity 122 of the inner pot 12 is avoided; in the sliding state, the matching surface 211 and the sliding surface 212 can be lapped on the support top surface 121 together, so that the steamer assembly 20 is stably erected on the steam base 10 through the matching surface 211 and the sliding surface 212, and the steamer 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] In the electric steamer provided by the embodiment of the present application, the sliding surface 212 is lower than the matching surface 211, so that a step structure capable of limiting the steamer assembly 20 is formed between the sliding surface 212 and the matching surface 211. Without the action of external force, the steamer assembly 20 can be stably erected on the steam base 10 through the matching surface 211, and 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 necessary to observe the water level in the steam cavity 122 or to add water to the steam cavity 122, the user can control the steamer assembly 20 to slide relative to the steam base 10 to the sliding state, and the user can observe the water level in the steam cavity 122 or add water to the steam cavity 122 through the misaligned part of the steamer assembly 20 and the steam base 10. After the operation is completed, the steamer assembly 20 is controlled to slide reversely relative to the steam base 10 to the working state, so that the steamer assembly 20 is lapped on the support top surface 121 again through the matching surface 211. In this way, when the water level in the steam cavity 122 is observed or water is added to the steam cavity 122, the steamer assembly 20 does not need to be taken off along the height direction, so that the user can be prevented from being scalded by high-temperature steam in the process of taking off the steamer assembly 20, and the condensed water on the steamer assembly 20 can also be prevented from scattering on the table top, so as to facilitate the user operation. In addition, the electric steamer 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 4As shown, the steaming rack 21 is provided with a plurality of steam holes 217, and steam in the steam cavity 122 can flow upward through the steam holes 217 to heat the food placed on the steaming rack 21. The steaming rack 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 steaming rack 21 itself, and the arrangement of the steam holes 217 between the reinforcing ribs 219 can prevent the steaming rack 21 from being locally deformed or even broken due to excessive steam holes 217, thereby further improving the strength and reliability of the steaming rack 21.

[0057] As shown in Figure 10 and Figure 21 In an embodiment, the steaming rack 21 is square, for example, rectangular or square. For ease of description, the following will be described by taking the rectangular steaming rack 21 as an example, wherein the first side edge 2181 is the long side of the rectangular steaming rack 21, and the second side edge 2183 is the short side of the rectangular steaming 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 steaming rack 21 has a first median line a perpendicular to the width direction (the Y-axis direction shown in the figure), two first side edges 2181 arranged on opposite sides of the first median line a, and two second side edges 2183 arranged on opposite sides of the first median line a; the steaming rack 21 further has a second median line d perpendicular to the length direction (the X-axis direction shown in the figure), and the two second side edges 2183 are arranged on opposite sides of the second median line d. The first side edge 2181 and the second side edge 2183 form a square steaming rack 21. Of course, in other embodiments, the steaming rack 21 can also be polygonal, circular, elliptical or other shapes, as long as the steaming rack assembly 20 can slide relative to the steam base 10, which is not limited in the embodiments of the present application.

[0058] As shown in Figures 3 to 4 The steaming rack assembly 20 further comprises a handle 22 arranged on the second side edge 2183. The user can take or place the steaming rack assembly 20 through the handle 22, and can also control the steaming rack assembly 20 to slide relative to the steam base 10 through the handle 22, so as to facilitate the user to operate. The handle 22 can be made of a material with a low thermal conductivity, such as plastic or silicone rubber, to prevent the user from being scalded. Specifically, the second side edge 2183 of the steaming 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 steaming 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 steaming rack assembly 20 to slide relative to the steam base 10 through the handle 22.

[0059] like Figures 2 to 3 As 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 fitting surface 211 and the sliding surface 212 satisfies: 0.5mm≤H1≤5mm. Wherein, the height difference H1 can be 0.5mm, 0.6mm……1mm, 2mm……5mm, etc. any value within the range of 0.5mm≤H1≤5mm. The height difference H1≥0.5mm can ensure that the step structure formed between the sliding surface 212 and the fitting surface 211 has a limiting effect on the steamer assembly 20, preventing the steamer assembly 20 from shifting 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 Figure 5 and Figure 16 The steamer 21 also includes a transition section 213 connected between the fitting surface 211 and the sliding surface 212. The transition section 213 allows the sliding surface 212 and the fitting surface 211 to be smoothly connected, so that the user can control the steamer assembly 20 to slide relative to the steam base 10, making the operation more smooth.

[0064] As shown in Figure 6 and Figure 20 The transition section 213 is provided with a convex portion 2131. The convex portion 2131 can reduce the contact area between the convex portion 2131 and the support top surface 121, and change the line-surface cooperation between the transition section 213 and the support top surface 121 to point-surface cooperation between the convex portion 2131 and the support top surface 121. Thus, the friction between the steamer assembly 20 and the support top surface 121 can be reduced, and the force required by the user to control the steamer assembly 20 to slide relative to the steam base 10 can be reduced, further making the operation more smooth. Specifically, the sliding direction of the steamer 21 relative to the support top surface 121 is along the width direction of the steamer 21, when the steamer assembly 20 can slide relative to the steam base 10 in the +Y axis direction to open, the convex portion 2131 is provided at one end of the transition section 213 facing the +Y axis direction; when the steamer assembly 20 can slide relative to the steam base 10 in the -Y axis direction to open, the convex portion 2131 is provided at one end of the transition section 213 facing the -Y axis direction; the sliding direction of the steamer 21 relative to the support top surface 121 is along the length direction of the steamer 21, when the steamer assembly 20 slides relative to the steam base 10 in the +X axis direction to open, the convex portion 2131 is provided at one end of the transition section 213 facing the +X axis direction; when the steamer assembly 20 slides relative to the steam base 10 in the -X axis direction to open, the convex portion 2131 is provided at one end of the transition section 213 facing the -X axis direction. And, the number of convex portions 2131 at both ends can be one or more, and the multiple convex portions 2131 are arranged at intervals.

[0065] As shown in 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 steaming rack 21. The condensed water on the steaming rack 21 can flow into the annular groove 215 and drip into the steam cavity 122 through the backflow hole 2151, preventing the accumulation of condensed water on the steaming rack 21 from affecting the cooking effect.

[0066] As shown in Figure 5 The steaming rack 21 further comprises a limiting portion 216, and the bottom surface of the limiting portion 216 is lower than the sliding surface 212. 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 will abut against the inner pot 12. The user can stop controlling the steaming rack assembly 20 to continue sliding when the limiting portion 216 abuts against the inner pot 12, avoiding the sliding distance of the steaming rack assembly 20 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 resulting in a side overturning, so as to limit the sliding range of the steaming rack assembly 20 relative to the steam base 10 by the limiting portion 216.

[0067] As shown in Figures 10 to 11 When the steaming rack assembly 20 can slide relative to the steam base 10 along the Y-axis direction, the distance L1 between any first side edge 2181 and the first center line a and the distance L2 between the outer side of the limiting portion 216 close to the first side edge 2181 and the first center line a satisfy: L1-L2≥20mm. In this way, the outer side of the limiting portion 216 is located on the side of the first center line a close to the corresponding first side edge 2181, further preventing the overall center of gravity of the steaming rack assembly 20 from being located outside the steam base 10 and resulting in a side overturning. At the same time, it also ensures 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 in the sliding state, the space exposed by the steam cavity 122 is large enough to facilitate the user to observe the water level in the steam cavity 122 or to add water to the steam cavity 122.

[0068] Specifically, as shown in Figure 10As shown, when the steam rack assembly 20 can slide relative to the steam base 10 along two directions on the Y-axis to the sliding state, the number of the limiting portions 216 is at least two, two limiting portions 216 are symmetrically arranged along the first center line a, or the distance between the outer side of the two limiting portions 216 and the first center line a is equal. And in the -Y-axis direction of the first center line a, 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; Similarly, in the +Y-axis direction of the first center line a, 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. The steam hole 217 is located between the outer sides of the two outermost limiting portions 216, that is, the steam hole 217 is located in the area surrounded by the two second side edges 2183 and the straight line b, the straight line c. In this way, it can be ensured that the projection of the steam hole 217 on the steam base 10 is located in the steam cavity 122 in the sliding state, preventing condensed water on the steam rack assembly 20 from dripping on the table top through the steam hole 217.

[0069] As shown, Figure 11 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 first side edge 2181 close to one of them 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 in the support area. The number of limiting portions 216 is at least one, for example, when the steam rack assembly 20 can slide relative to the steam base 10 along the +Y-axis direction to the sliding state, in the +Y-axis direction of the first center line a, 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, the two second side edges 2183 and the first side edge 2181 in the +Y-axis direction, the straight line b forms 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 forms a support area. In this way, it can also be ensured that the projection of the steam hole 217 on the steam base 10 is located in the steam cavity 122 in the sliding state, preventing condensed water on the steam rack assembly 20 from dripping on the table top through the steam hole 217.

[0070] Similarly, as shown, Figures 21 to 22 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 center line d and the distance L4 between the outer side of the limiting portion 216 close to the second side edge 2183 and the second center line d satisfy: L3-L4≥20mm.

[0071] As shown, Figure 21As shown, when the steaming rack assembly 20 is capable of sliding relative to the steam base 10 along two directions on the X-axis to the sliding state, the number of the limiting portions 216 is at least two, the two limiting portions 216 are symmetrically arranged along the second center line d, or the distance between the outer sides of the two limiting portions 216 and the second center line d is equal. And in the -X-axis direction of the second center line d, the distance between the second side edge 2183 and the outer side of the limiting portion 216 close to the second side edge 2183 is greater than or equal to 20 mm; similarly, in the +X-axis direction of the second center line d, the distance between the second side edge 2183 and the outer side of the limiting portion 216 close to the second side edge 2183 is greater than or equal to 20 mm. The steam hole 217 is located between the outer sides of the two outermost limiting portions 216, that is, the steam hole 217 is located in the area enclosed by the two first side edges 2181 and the straight line e and the straight line f.

[0072] As shown, Figure 22 when the steaming rack assembly 20 is capable of sliding relative to the steam base 10 along a single direction on the X-axis to the sliding state, the number of the limiting portions 216 is at least one. Taking the case that the steaming rack assembly 20 is capable of sliding relative to the steam base 10 along the -X-axis direction to the sliding state as an example, in the -X-axis direction of the second center line d, the distance between the second side edge 2183 and the outer side of the limiting portion 216 close to the second side edge 2183 is greater than or equal to 20 mm, the two first side edges 2181, the second side edge 2183 in the -X-axis direction, and the straight line e enclose a sliding area, and the two first side edges 2181, the second side edge 2183 in the +X-axis direction, and the straight line e enclose a support area.

[0073] As shown, Figures 4 to 6 In an embodiment, the limiting portion 216 is located in the supporting area. The supporting area has a larger space to facilitate the processing of the limiting portion 216. Among them, the limiting portion 216 can include a protruding groove formed by recessing downward from the bottom wall of the steaming rack 21, that is, the front surface of the steaming rack 21 will form a groove structure. The limiting portion 216 can be processed by stamping forming, which is simple and convenient in processing method and low in cost. And in order to prevent the condensed water on the steaming rack 21 from flowing into the groove structure and accumulating in the groove structure to affect the cooking effect, the limiting portion 216 is provided with a first through hole 2161 penetrating through the steaming rack 21. In this way, the condensed water flowing into the groove structure can be dropped into the steam cavity 122 through the first through hole 2161.

[0074] Alternatively, the limiting portion 216 can also include a protrusion provided on the lower surface of the bottom wall of the steaming rack 21, that is, no groove structure is formed on the front surface of the steaming rack 21. Avoiding the bottom of the groove structure formed on the front surface of the steaming rack 21 being lower than other areas on the supporting area, which causes the condensed water on the supporting area to flow into the groove structure and accumulate in the groove structure to affect the cooking effect.

[0075] As shown, 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.

[0076] As shown in Figure 11 and Figure 20 shown, 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, further improving the stability and reliability of the steaming rack assembly 20 on the steam base 10.

[0077] Alternatively, as shown in Figures 8 to 9As shown, in order to avoid the second backflow groove 2153 being too deep to cause bending deformation or even breakage due to the low cross-sectional moment of inertia of the section, and to improve the manufacturability of the steamer 21, the second backflow groove 2153 can also be removed. The limiting portion 216 can also include a protrusion provided on the lower surface of the bottom wall of the steamer 21, i.e., the limiting portion 216 is provided on the back of the first backflow groove 2152. Moreover, the limiting portion 216 can be arranged corresponding to the backflow hole 2151, and is provided with a third through hole 2162 in communication with the backflow hole 2151. The condensed water on the steamer 21 can flow into the first backflow groove 2152, and the condensed water in the first backflow groove 2152 can drip into the steam cavity 122 through the backflow hole 2151 and the third through hole 2162. When the user controls the steamer assembly 20 to slide relative to the steam base 10 to the sliding state, the sliding range of the steamer assembly 20 relative to the steam base 10 can be limited by the limiting portion 216, so as to avoid the distance of the steamer assembly 20 sliding relative to the steam base 10 being too large, which causes the overall center of gravity of the steamer assembly 20 to be located outside the steam base 10 and the steamer assembly 20 to be overturned.

[0078] As shown in FIG. 9, the limiting portion 216 includes a limiting segment 2163 and a mounting segment 2164. The mounting segment 2164 is connected with the steamer 21, so that the limiting segment 2163 is attached to the back of the steamer 21. Specifically, the steamer 21 is provided with a mounting hole, and the mounting segment 2164 is inserted into the mounting hole. The limiting portion 216 can be a silica gel piece, so as to facilitate production and assembly, and also to play a buffering role when the limiting portion 216 abuts against the inner pot 12, so as to protect the steamer 21 and the inner pot 12. Figures 8 to 9 As shown in FIG. 9, the steamer 21 is also provided with an egg steaming groove 214, and the bottom wall of the egg steaming groove 214 is provided with a second through hole 2141. The egg steaming groove 214 is used for placing eggs to avoid the eggs rolling on the steamer 21. Since the egg steaming groove 214 is a downwardly recessed structure, the bottom wall of the egg steaming groove 214 is lower than other areas on the steamer 21, and the condensed water on the steamer 21 can flow into the egg steaming groove 214. The second through hole 2141 enables the condensed water flowing into the egg steaming groove 214 to drip into the steam cavity 122, so as to prevent the condensed water from accumulating in the egg steaming groove 214 and affecting the cooking effect. The number of the egg steaming groove 214 can be one, two or more, and the plurality of egg steaming grooves 214 are arranged at intervals.

[0079] Figures 4 to 5 As shown in FIG. 9, the steamer 21 is also provided with an egg steaming groove 214, and the bottom wall of the egg steaming groove 214 is provided with a second through hole 2141. The egg steaming groove 214 is used for placing eggs to avoid the eggs rolling on the steamer 21. Since the egg steaming groove 214 is a downwardly recessed structure, the bottom wall of the egg steaming groove 214 is lower than other areas on the steamer 21, and the condensed water on the steamer 21 can flow into the egg steaming groove 214. The second through hole 2141 enables the condensed water flowing into the egg steaming groove 214 to drip into the steam cavity 122, so as to prevent the condensed water from accumulating in the egg steaming groove 214 and affecting the cooking effect. The number of the egg steaming groove 214 can be one, two or more, and the plurality of egg steaming grooves 214 are arranged at intervals.

[0080] As shown in FIG. 9, the steamer 21 is also provided with an egg steaming groove 214, and the bottom wall of the egg steaming groove 214 is provided with a second through hole 2141. The egg steaming groove 214 is used for placing eggs to avoid the eggs rolling on the steamer 21. Since the egg steaming groove 214 is a downwardly recessed structure, the bottom wall of the egg steaming groove 214 is lower than other areas on the steamer 21, and the condensed water on the steamer 21 can flow into the egg steaming groove 214. The second through hole 2141 enables the condensed water flowing into the egg steaming groove 214 to drip into the steam cavity 122, so as to prevent the condensed water from accumulating in the egg steaming groove 214 and affecting the cooking effect. The number of the egg steaming groove 214 can be one, two or more, and the plurality of egg steaming grooves 214 are arranged at intervals. Figure 7 ​As 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.

[0081] 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. Any numerical value 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.

[0082] As shown in Figure 1 , the steam pot with slidable water adding function can further include a cage 30. When only one layer of steaming rack assembly 20 needs to be arranged, the cover body 40 can be covered 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 body 40 is covered on the top layer of steaming rack assembly 20.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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.
