Description

TECHNICAL FIELD

[0001] The utility model relates to the field of household appliances, in particular to a steam cooking utensil. BACKGROUND

[0002] The existing steam cooking utensil, such as electric steamer, comprises a steam base and a steamer assembly, and the steamer assembly and the steam base are usually matched through a stepped surface to limit the steamer assembly on the steam base, avoiding the movement of the steamer assembly relative to the steam base along the horizontal direction. When using, since the water amount is invisible, the whole steamer assembly needs to be taken down along the height direction when adding water in the middle, which is easy to be scalded by steam, and the condensed water on the steaming rack will also fall on the table surface, which is very inconvenient.

[0003] And some existing steamer assemblies are mainly formed by plastic injection molding or hardware material stretching molding, regardless of the material, the whole steamer assembly needs to be taken down when adding water. The applicant designs a steam cooking utensil with a steamer assembly capable of sliding relative to the steam base, and the existing steamer structure cannot meet the sliding relative to the steam base. SUMMARY

[0004] Therefore, it is necessary to provide a steam cooking utensil to make the steamer assembly slide relative to the steam base.

[0005] The utility model provides a steam cooking utensil, which comprises a steam base with a supporting top surface and a steamer assembly comprising a cage body, wherein the cage body comprises a side plate and a bottom plate, the lower end of the side plate is provided with a first bending part bent towards the inside of the cage body, the bottom plate comprises a frame body and a second bending part located at the outer edge of the frame body, the first bending part is sleeved outside the second bending part and is press-bonded to form a matching surface, the frame body is further provided with a sliding surface, the sliding surface is the lowest surface of the frame body, the steamer assembly can slide relative to the steam base and has a working state and a sliding state, in the working state, the matching surface is lapped on the supporting top surface, and in the sliding state, the matching surface and the sliding surface are jointly lapped on the supporting top surface.

[0006] In the steamer assembly, in the working state, the matching surface can be overlapped on the supporting top surface, the steamer assembly completely covers the steam base, the internal structure of the steam base is not exposed, and leakage of steam in the steam base is avoided. When it is necessary to observe the water level in the steam base or to add water to the steam base, the steamer assembly can be controlled to slide relative to the steam base to the sliding state. In the sliding state, the matching surface and the sliding surface can be overlapped on the supporting top surface, so that the steamer assembly is partially misaligned with the steam base. The first bending part is sleeved outside the second bending part, which can enhance the strength of the first bending part and the second bending part, ensure the strength of the matching surface formed by the pressure connection and molding of the two, and prevent the matching surface from being deformed, thereby ensuring the stability and reliability of the steamer assembly erected on the steam base. The side plate and the bottom plate are fixedly connected to form an integrated steamer assembly through the first bending part and the second bending part. Compared with the traditional method of stretching a whole piece of hardware material to form a steamer, the stretching, edge cutting, polishing and other processes can be omitted, the cost is reduced, and the user can easily take or place the steamer assembly.

[0007] In one of the embodiments, the height difference H1 between the sliding surface and the matching surface satisfies 0.5mm≤H1≤5mm.

[0008] In this way, the step structure formed between the sliding surface and the matching surface can limit the steamer assembly and prevent the steamer assembly from deviating relative to the steam base. At the same time, the inclination angle of the steamer assembly can be prevented from being too large when the user controls the steamer assembly to slide relative to the steam base.

[0009] In one of the embodiments, the second bending part and the first bending part each have a rounded segment, the outer wall surface of the second bending part of the rounded segment is attached to the inner wall surface of the first bending part of the rounded segment, and the matching surface is located at the rounded segment of the first bending part.

[0010] In this way, the rounded segment can improve the connection strength between the side plate and the bottom plate, prevent the matching surface from being deformed, and ensure that the matching surface has high flatness. The rounded segment also makes the matching surface and the supporting top surface have linear surface matching, which has better fitting degree, so that the steamer assembly and the supporting top surface have strong sealing property.

[0011] In one of the embodiments, the rounded segment of the second bending part is in interference fit with the rounded segment of the first bending part.

[0012] In this way, the rounded segment of the second bending part and the rounded segment of the first bending part have strong sealing property.

[0013] In one of the embodiments, the bottom plate further comprises a first transition section connecting the outer edge of the frame body with the second bending part, and the first transition section is arranged upwardly and obliquely from the frame body.

[0014] In this way, the first transition section allows the bottom plate to be integrally formed, thereby facilitating the processing of the bottom plate.

[0015] In one of the embodiments, the first transition section and the sliding surface form an obtuse angle.

[0016] In this way, the first transition section can serve as a guide and can generate an effective upwardly oblique thrust on the steamer assembly through the cooperation of the first transition section and the steam base, thereby making it easier for the user to control the sliding opening of the steamer assembly relative to the steam base.

[0017] In one of the embodiments, a second transition section is further arranged between the first transition section and the outer edge of the frame body, and an arc-shaped protrusion is arranged on the second transition section.

[0018] In this way, the second transition section allows the first transition section and the outer edge of the frame body to be smoothly connected, and the arc-shaped protrusion can reduce the contact area between the steamer assembly and the supporting top surface, thereby reducing the force required to be exerted by the user when controlling the sliding of the steamer assembly relative to the steam base, and making the operation of the user more smooth.

[0019] In one of the embodiments, the bottom plate further comprises a limiting rib arranged on the bottom surface of the frame body, and the bottom surface of the limiting rib is lower than the sliding surface.

[0020] In this way, the limiting rib can limit the sliding range of the steamer assembly relative to the steam base, thereby avoiding the distance of the sliding of the steamer assembly relative to the steam base being too large, and causing the overall center of gravity of the steamer assembly to be located outside the steam base and thereby causing the steamer assembly to overturn.

[0021] In one of the embodiments, the steamer assembly further comprises a handle, and the handle is arranged on the side plate.

[0022] In this way, the user can control the sliding of the steamer assembly relative to the steam base through the handle, and arranging the handle on the side plate can facilitate the user to exert force.

[0023] In one of the embodiments, the steamer assembly is square-shaped, and the sliding direction of the steamer assembly relative to the supporting top surface is along the length direction or the width direction of the steamer assembly.

[0024] In this way, the user can control the steamer assembly to slide relative to the steam base along the length direction or the width direction of the steamer assembly, so as to switch between the working state and the sliding state. BRIEF DESCRIPTION OF DRAWINGS

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 term "and / or" includes any and all combinations of one or more of the associated listed items.

[0038] The existing steam cooking utensils, such as electric steamers, include a steam base and a steamer assembly, and generally the steamer assembly and the steam base are matched by a 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. When using it, since the water amount is not visible, 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 steaming rack will also scatter on the table surface, which is very inconvenient. Some existing steamer assemblies are mainly formed by plastic injection molding or hardware material stretching molding, regardless of the material, the whole steamer assembly needs to be taken down when adding water. The applicant designs a steam cooking utensil with a steamer assembly capable of sliding relative to the steam base, and the existing steamer structure cannot meet the sliding relative to the steam base.

[0039] In order to solve the above problems, as shown in Figures 1 to 9 The present application provides a steam cooking utensil, so that the steamer assembly can slide relative to the steam base.

[0040] As shown in Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, specifically, the steam cooking appliance includes a steam base 200 and a steamer assembly 100, wherein: the steam base 200 has a support top surface 202, the steamer assembly 100 includes a cage body, the cage body includes a side plate 20 and a bottom plate 10, the lower end of the side plate 20 has a first bending portion 21 bent towards the inside of the cage body, the bottom plate 10 includes a frame body 11 and a second bending portion 12 located at the outer edge of the frame body 11, the first bending portion 21 is sleeved outside the second bending portion 12 and is press-fit to form a matching surface 22, and the frame body 11 is further provided with a sliding surface 13, which is the lowest surface of the frame body 11; the steamer assembly 100 can slide relative to the steam base 200 and has a working state and a sliding state; in the working state, the matching surface 22 is lapped on the support top surface 202; and in the sliding state, the matching surface 22 and the sliding surface 13 are jointly lapped on the support top surface 202.

[0041] As shown in Figures 1 to 2 The steam base 200 is provided with a heating base 203 and an inner pot 201, the inner pot 201 is arranged on the heating base 203, and the inner pot 201 has a steam cavity. The support top surface 202 can be the top surface of the heating base 203 or the top surface of the inner pot 201.

[0042] In the steam cooking appliance provided by the embodiment of the utility model, the steamer assembly 100 can be arranged on the support top surface 202 of the steam base 200, in the working state, the matching surface 22 can be lapped on the support top surface 202, the steamer assembly 100 completely covers the steam base 200, the internal structure of the steam base 200 is not exposed, and steam leakage in the steam base 200 is avoided; since the sliding surface 13 is the lowest surface of the frame body 11, the sliding surface 13 is lower than the matching surface 22, a step structure capable of limiting the steamer assembly 100 is formed between the sliding surface 13 and the matching surface 22, and the steamer assembly 100 can be stably arranged on the support top surface 202 without external force; when it is necessary to observe the water level in the inner pot 201 or to add water into the inner pot 201, the steamer assembly 100 can be controlled to slide relative to the steam base 200 to the sliding state, in the sliding state, the matching surface 22 and the sliding surface 13 can be jointly lapped on the support top surface 202, the steamer assembly 100 is stably arranged on the steam base 200 through the sliding surface 13, the steamer assembly 100 is partially misaligned with the steam base 200, the inner pot 201 is partially exposed, and the user can observe the water level in the inner pot 201 or add water into the inner pot 201 through the misaligned part of the steamer assembly 100 and the steam base 200; finally, the steamer assembly 100 is controlled to reversely slide relative to the steam base 200 to the working state, so that the steamer assembly 100 is lapped on the support top surface 202 again through the matching surface 22.

[0043] And, the first bending part 21 is sleeved on the outside of the second bending part 12, which can enhance the strength of the first bending part 21 and the second bending part 12, ensure the strength of the matching surface 22 formed by the pressure bonding and molding of the two, so that the matching surface 22 is not easy to deform, thereby ensuring the stability and reliability of the steamer assembly 100 erected on the steam base 200. The side plate 20 and the bottom plate 10 are fixedly connected to form an integrated steamer assembly 100 through the first bending part 21 and the second bending part 12, which can facilitate the user to take or place the steamer assembly 100, and also facilitate the user to control the sliding of the steamer assembly 100 relative to the steam base 200.

[0044] As shown in Figure 3 The frame body 11 is provided with a plurality of steam holes 111, and the heating base 203 can heat the water in the inner pot 201 to generate steam, which flows upward through the steam holes 111 to heat the food placed on the frame body 11.

[0045] In an embodiment, the steamer assembly 100 is square, such as rectangular or square. It should be noted that the steamer assembly 100 being square means that its cross section is generally square, and the four corners of the square can be right angles or rounded corners. Of course, in other embodiments, the steamer assembly 100 can also be polygonal, circular or other shapes, as long as it can slide relative to the steam base 200, which is not specifically limited in the embodiments of the present application. For ease of description, the following will be described by taking the steamer assembly 100 as a rectangular structure, in which the long side of the bottom plate 10 extends along the X-axis direction and the short side extends along the Y-axis direction.

[0046] As shown in Figures 1 to 2 The operation interface of the steam cooking appliance is the front face, i.e. the front face of the steam cooking appliance, and the opposite face is the rear face, i.e. the direction of the steam base 200 ± Y-axis. Similarly, the two sides of the operation interface can be understood as the left and right faces of the steam cooking appliance, i.e. the direction of the steam base 200 ± X-axis.

[0047] In an embodiment, the sliding direction of the steamer assembly 100 relative to the support top surface 202 is along the width direction of the steamer assembly 100, i.e. the steamer assembly 100 can slide relative to the steam base 200 along the ± Y-axis direction, i.e. the front and rear directions, wherein the + Y-axis direction is the rear side and the - Y-axis direction is the front side. The user can control the steamer assembly 100 to slide relative to the steam base 200 along the - Y-axis direction to the sliding state, and control the steamer assembly 100 to slide relative to the steam base 200 in the opposite direction along the + Y-axis direction to the working state; or control the steamer assembly 100 to slide relative to the steam base 200 along the + Y-axis direction to the sliding state, and control the steamer assembly 100 to slide relative to the steam base 200 in the opposite direction along the - Y-axis direction to the working state.

[0048] In another embodiment, the steamer assembly 100 slides relative to the supporting top surface 202 along its length, meaning the steamer assembly 100 can slide relative to the steam base 200 along the ±X-axis direction, i.e., left and right. The +X-axis direction is the right side, and the -X-axis direction is the left side. The user can control the steamer assembly 100 to slide relative to the steam base 200 along the -X-axis direction to a sliding state, and control the steamer assembly 100 to slide in the opposite direction relative to the steam base 200 along the +X-axis direction to a working state; alternatively, the user can control the steamer assembly 100 to slide relative to the steam base 200 along the +X-axis direction to a sliding state, and control the steamer assembly 100 to slide in the opposite direction relative to the steam base 200 along the -X-axis direction to a working state.

[0049] like Figure 8 As shown, the height difference H1 between the sliding surface 13 and the mating surface 22 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. A height difference H1 ≥ 0.5mm ensures the limiting effect of the stepped structure formed between the sliding surface 13 and the mating surface 22 on the steamer assembly 100, preventing the steamer assembly 100 from shifting relative to the steam base 200 and ensuring the steamer assembly 100 can be stably mounted on the steam base 200. A height difference H1 ≤ 5mm prevents the steamer assembly 100 from sliding open relative to the steam base 200 when the user controls it, causing the mating surface 22 and the sliding surface 13 to overlap the supporting top surface 202, resulting in an excessively large tilt angle.

[0050] like Figures 8 to 9 As shown, in one embodiment, both the second bending portion 12 and the first bending portion 21 have a rolled section. The outer wall surface of the rolled section of the second bending portion 12 is attached to the inner wall surface of the rolled section of the first bending portion 21, and the mating surface 22 is located at the rolled section of the first bending portion 21. The mating of the second bending portion 12 and the first bending portion 21 of the rolled section can improve the connection strength between the side plate 20 and the bottom plate 10, making the mating surface 22 less prone to deformation and ensuring that the mating surface 22 has a high degree of flatness, thereby improving the stability and reliability of the steamer assembly 100 mounted on the steam base 200. Furthermore, the rolled section also makes the mating surface 22 and the supporting top surface 202 a line-to-surface fit. Compared with a surface-to-surface fit, the line-to-surface fit makes the mating surface 22 and the supporting top surface 202 fit better, thereby giving the steamer assembly 100 and the supporting top surface 202 a strong seal, ensuring that the steam in the inner pot 201 will not overflow from the gap between the steamer assembly 100 and the supporting top surface 202.

[0051] Of course, in other embodiments, the outer wall surface of the first bent portion 21 of the rounded segment can be attached to the inner wall surface of the second bent portion 12 of the rounded segment, and the matching surface 22 is located in the rounded segment of the second bent portion 12. Alternatively, the first bent portion 21 and the second bent portion 12 can also be other bent forms, such as a rectangular, triangular, or other regular or irregular shape of the cross section of the bent structure, as long as it can ensure reliable connection between the side plate 20 and the bottom plate 10, and form the matching surface 22, and the embodiments of the present application do not make specific limitations here.

[0052] As shown in Figures 8 to 9 , the rounded segment of the second bent portion 12 is in interference fit with the rounded segment of the first bent portion 21. In this way, the rounded segment of the second bent portion 12 and the rounded segment of the first bent portion 21 have strong sealing property, which ensures that the condensed water in the steamer assembly 100 does not overflow from the gap between the second bent portion 12 and the first bent portion 21.

[0053] As shown in Figures 8 to 9 , the bottom plate 10 further comprises a first transition section 14 connecting the outer edge of the frame body 11 and the second bent portion 12, and the first transition section 14 is inclined upward from the frame body 11. The first transition section 14 is used to connect the frame body 11 and the second bent portion 12, so that the bottom plate 10 can be integrally formed to facilitate the processing of the bottom plate 10.

[0054] As shown in Figures 8 to 9 , the first transition section 14 and the sliding surface 13 have an obtuse angle α. Since the sliding surface 13 is lower than the matching surface 22, when the user controls the steamer assembly 100 to slide relative to the steam base 200 to open, the steamer assembly 100 can first slide from the state that the matching surface 22 is lapped on the support top surface 202 to the state that the first transition section 14 abuts against the support top surface 202, and then slide along the first transition section 14 to the state that the matching surface 22 and the sliding surface 13 are lapped on the support top surface 202 together. The first transition section 14 can play a guiding role, and can generate an effective upward inclined thrust on the steamer assembly 100 through the cooperation of the first transition section 14 and the steam base 200, so that the user controls the steamer assembly 100 to slide relative to the steam base 200 to open more labor-saving. Moreover, the greater the angle α, the smaller the force required by the user to control the steamer assembly 100 to slide relative to the steam base 200, and the more smooth the user's operation.

[0055] As shown in Figure 5 , Figure 6 , and Figure 9As shown, the first transition section 14 and the outer edge of the frame body 11 are further provided with a second transition section 15, and the second transition section 15 is provided with an arc-shaped protrusion 151. The second transition section 15 enables the first transition section 14 and the outer edge of the frame body 11 to be smoothly connected, so as to facilitate the user to control the steamer assembly 100 to slide relative to the steam base 200. Moreover, the arc-shaped protrusion 151 can reduce the contact area between the steamer assembly 100 and the support top surface 202, and change the line-surface cooperation between the second transition section 15 and the support top surface 202 into point-surface cooperation between the arc-shaped protrusion 151 and the support top surface 202. Thus, the friction between the steamer assembly 100 and the support top surface 202 can be reduced, and the force required to be exerted by the user to control the steamer assembly 100 to slide relative to the steam base 200 can be reduced, so that the user operation is more smooth. Specifically, when the sliding direction of the steamer assembly 100 is the Y-axis direction, the arc-shaped protrusion 151 is arranged at both ends of the second transition section 15 along the Y-axis direction; when the sliding direction of the steamer assembly 100 is the X-axis direction, the arc-shaped protrusion 151 is arranged at both ends of the second transition section 15 along the X-axis direction.

[0056] As shown in FIG. 1, the bottom plate 10 further comprises a limiting rib 16 arranged on the bottom surface of the frame body 11, and the bottom surface of the limiting rib 16 is lower than the sliding surface 13. Figure 5 As shown in FIG. 1, the bottom plate 10 further comprises a limiting rib 16 arranged on the bottom surface of the frame body 11, and the bottom surface of the limiting rib 16 is lower than the sliding surface 13. Figure 7 As shown in FIG. 1, the bottom plate 10 further comprises a limiting rib 16 arranged on the bottom surface of the frame body 11, and the bottom surface of the limiting rib 16 is lower than the sliding surface 13.

[0057] As shown in FIG. 1, the bottom plate 10 further comprises a limiting rib 16 arranged on the bottom surface of the frame body 11, and the bottom surface of the limiting rib 16 is lower than the sliding surface 13. Figures 4 to 5 As shown in FIG. 1, the limiting rib 16 can be processed by stamping forming, so that a groove structure is formed on the top surface of the frame body 11 at the corresponding position of the limiting rib 16. In order to prevent the condensed water on the frame body 11 from flowing into the groove structure and accumulating in the groove structure to affect the cooking effect, a through hole 161 can be arranged on the bottom of the limiting rib 16, so that the condensed water flowing into the groove structure can drip into the inner pot 201 through the through hole 161.

[0058] As shown in FIG. 1, the bottom plate 10 further comprises a limiting rib 16 arranged on the bottom surface of the frame body 11, and the bottom surface of the limiting rib 16 is lower than the sliding surface 13. Figure 4As shown, the steamer assembly 100 further comprises a handle 30 arranged on the side plate 20. A user can control the steamer assembly 100 to slide relative to the steam base 200 through the handle, and arranging the handle 30 on the side plate 20 can facilitate the user to apply force. The handle 30 can be made of a material with low thermal conductivity, such as silicone rubber, to prevent the user from being scalded.

[0059] As shown in Figure 1 and Figure 3 The steam cooking appliance can further comprise a cover 300, and the number of the steamer assemblies 100 can be one, two or more, and the plurality of steamer assemblies 100 are arranged in layers, and the cover 300 is arranged on the top layer of the steamer assemblies 100.

[0060] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure.

[0061] The above-mentioned embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present disclosure. It should be noted that, for those skilled in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the appended claims.
