Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and in particular to a cooking equipment. Background Art

[0002] At present, in the process of cooking food in electric steamers on the market, a large amount of condensed water usually forms on the food, resulting in a decline in the taste of the food. Therefore, how to provide an electric steamer that reduces the condensed water on the food has become an urgent problem to be solved. Summary of the Utility Model

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, the utility model provides a cooking equipment, comprising: a heating component; a steamer component disposed on the heating component, the steamer component includes an inner steamer and an outer steamer, the inner steamer is disposed inside the outer steamer, a steam channel is provided between the inner steamer and the outer steamer, at least a part of the steam channel is located at the bottom of the inner steamer, and the heating component is used to supply steam into the steam channel; a cover body covering the steamer component, a cavity is formed between the cover body and the steamer component, and the cavity is communicated with the steam channel.

[0005] The steamer component is placed on the heating component. During the operation of the heating component, the water inside it will be heated, so that the heating component can generate steam, and the steam generated by the heating component can be discharged into the steamer component.

[0006] The steamer component includes an inner steamer and an outer steamer. The inner steamer is fixed on the outer steamer, and the inner steamer is used for steaming food. A steam channel is formed between the inner steamer and the outer steamer, and the heating component is communicated with the steam channel, so that the steam generated by the heating component can flow into the steam channel.

[0007] The cover body is buckled on the steamer component, so that a cavity is formed between the cover body and the steamer component, and the cavity is communicated with the steam channel. Therefore, the steam in the steam channel can flow into the cavity. The heating component, the steam channel and the cavity are sequentially communicated, so that the steam can flow between the heating component, the steam channel and the cavity. When the steam content in the cavity is relatively high, a part of the steam can flow back into the steam channel, so that a circulating flow of steam is formed between the heating component, the steam channel and the cavity.

[0008] At least a part of the steam passage is located at the bottom of the inner steamer, and the cavity is located at the top of the inner steamer. Therefore, steam circulates at both the top and the bottom of the inner steamer. Under the circulation of the steam, the temperature of the steam everywhere between the heating component, the steam passage and the cavity is basically the same, so that the temperature of the top of the inner steamer and the bottom of the inner steamer is basically consistent, and there is a small temperature difference between the top and the bottom of the inner steamer. Steam cannot condense near the inner steamer, thereby reducing the condensed water on the food and ensuring the cooking texture of the food.

[0009] Compared with the straight-up-and-down perforated steamer in the related art, in the cooking device of this solution, during the cooking process, steam will not directly pass through the inner steamer, thus avoiding steam directly passing through the food. Usually, steam contains a lot of moisture. By avoiding steam passing through the food, the probability of moisture contacting the food can be reduced, thereby reducing the moisture accumulated on the surface of the food and further ensuring the cooking texture of the food.

[0010] In addition, according to the cooking device in the above technical solution provided by the present utility model, it may also have the following additional technical features:

[0011] In some technical solutions, optionally, the outer steamer includes a top wall, and a plurality of communication holes are provided on the top wall. The steam passage and the cavity are connected through the communication holes.

[0012] A plurality of communication holes are opened at the top of the outer steamer. The steam in the steam passage can flow to the cavity through the communication holes, and the steam in the cavity can also flow back to the steam passage through the communication holes.

[0013] The communication holes are provided at the top of the outer steamer. The steam in the steam passage will flow from the top of the inner steamer to the side of the inner steamer, and then the steam will flow along the side of the inner steamer to the top of the inner steamer. Through the above method, the steam flows through both the bottom and the side of the inner steamer, so that steam circulates at the top, side and bottom of the inner steamer. And because the temperature difference of the steam everywhere inside the cooking device is small, the temperature difference between the top, side and bottom of the inner steamer is small, further improving the temperature uniformity of each part of the inner steamer, thereby further reducing the condensed water generated on the food surface.

[0014] In some technical solutions, optionally, the top of the outer steamer is provided with an opening, the top wall is distributed along the circumference of the opening, and the inner steamer is placed into or separated from the outer steamer through the opening.

[0015] The outer steamer has a structure with an opening at the top. The inner steamer can be placed into the outer steamer through the opening. After the cooking is completed, the inner steamer can be taken out of the outer steamer through the opening, so as to facilitate the user to take the food in the inner steamer. The separable form of the inner steamer and the outer steamer is convenient for the user to clean the inner steamer and the outer steamer separately, avoiding cleaning blind spots.

[0016] The top wall of the outer steamer is distributed along the circumference of the opening, so that a plurality of connecting holes can be distributed on the circumference of the inner steamer. The plurality of connecting holes can allow steam to pass through at the same time, so that steam flows through the circumference of the inner steamer, which is beneficial to improving the uniformity of heating of the inner steamer, which can not only improve the cooking effect of food, but also avoid the generation of condensed water.

[0017] In some technical solutions, optionally, the top wall is inclined toward the opening.

[0018] The top wall in the present solution is an inclined structure, wherein the top wall is inclined toward the opening, and the top wall is an annular structure, so the top wall is formed in a form of a high outer ring and a low inner ring.

[0019] The steam in the steam channel flows into the cavity through the opening. Since the top wall is inclined inward, the steam flowing out of the steam channel will also gather toward the upper middle part of the inner steamer, making the top temperature of the inner steamer higher. This method can further reduce the temperature difference between the top and the bottom of the inner steamer, further improve the uniformity of temperature at various places in the inner steamer, and reduce condensation water generated on the surface of food.

[0020] In some technical solutions, optionally, the top of the inner steamer fits with the top of the outer steamer in the circumferential direction.

[0021] When the inner steamer is placed on the outer steamer, the top of the inner steamer fits with the top of the outer steamer, and the steam is not easy to flow along the position where the inner steamer and the outer steamer fit each other, so that most of the steam between the cavity and the steam channel flows through the connecting holes. The multiple connecting holes are distributed around the inner steamer, and the steam flows through the connecting holes, which can improve the uniformity of steam distribution around the inner steamer. If there is a local leak in the fitting position of the inner steamer and the outer steamer, it is easy to cause the problem of steam concentration in the local position of the inner steamer. Therefore, through the above method, the circumferential heating uniformity of the inner steamer is guaranteed.

[0022] In some technical solutions, optionally, a first step portion is provided on the top edge of the inner steamer, a second step portion is provided on the top wall, and the first step portion is overlapped on the second step portion.

[0023] The top edge of the inner steamer is overlapped on the top edge of the outer steamer. In this solution, a first step portion is formed on the top edge of the inner steamer, and the first step portion is distributed along the circumference of the inner steamer. A second step portion is formed on the top wall of the outer steamer, and the second step portion is distributed along the circumference of the outer steamer.

[0024] When the inner steamer is placed inside the outer steamer, the first stepped portion overlaps with the second stepped portion. Both the first stepped portion and the second stepped portion are stepped structures. Therefore, there are multiple vertical and horizontal fitting structures between the first stepped portion and the second stepped portion, thereby increasing the contact area between the first stepped portion and the second stepped portion, which is beneficial to improving the sealing effect between the inner steamer and the outer steamer, preventing steam from flowing through the position where the inner steamer and the outer steamer are in contact with each other, and ensuring the circumferential uniform heating of the inner steamer.

[0025] When the first stepped portion and the second stepped portion overlap each other, the second stepped portion can limit the first stepped portion, and the first stepped portion is not prone to moving relative to the second stepped portion, thereby ensuring the placement stability of the inner steamer on the outer steamer and preventing the inner steamer from shaking relative to the outer steamer.

[0026] In some technical solutions, optionally, the number of steamer assemblies is at least two layers, and the outer steamer in one layer of the steamer assembly overlaps with the outer steamer in the adjacent steamer assembly.

[0027] The cooking device includes at least two layers of steamer assemblies. Users can, according to their cooking needs, place one layer of the steamer assembly on the heating assembly, or place multiple layers of the steamer assembly on the heating assembly.

[0028] When multiple layers of steamer assemblies are stacked on the heating assembly, the outer steamer in one layer of the steamer assembly is placed on the outer steamer in the lower layer of the steamer assembly, thereby realizing the stacking of multiple layers of steamer assemblies.

[0029] When multiple layers of steamer assemblies are stacked, since the communication holes are vertically provided, the steam channels in adjacent two layers of steamer assemblies are interconnected. During the cooking process, the steam generated by the heating assembly first flows into the steam channel of the lowermost layer of the steamer assembly, and then the steam sequentially flows upward into the steam channels of the upper layers, and the steam in the steam channel of the uppermost layer flows into the cavity.

[0030] In some technical solutions, optionally, at least one layer of the steamer assembly further includes: a steaming plate, which overlaps on the inner steamer and / or the outer steamer, the steaming plate covers the opening, and ventilation holes are provided on the steaming plate, and the ventilation holes are connected to the inner cavity of the inner steamer so that steam can flow into the inner cavity of the inner steamer through the ventilation holes.

[0031] The steaming plate can be placed on the inner steamer and / or the outer steamer, and ingredients can be placed on the steaming plate. Ventilation holes are provided on the steaming plate, and steam can flow into the interior of the inner steamer through the ventilation holes, thereby heating the ingredients in the inner steamer.

[0032] In the case where the steamer assembly has only one layer, a steaming plate can be placed on the inner steamer and / or the outer steamer. When food is placed on the steaming plate, the food is located in the space between the steaming plate and the cover body. In the case where the steamer assembly has multiple layers, a steaming plate can be placed on the inner steamer and / or the outer steamer of the topmost layer, so as to place food ingredients on the steaming plate. Alternatively, in the case where the steamer assembly has multiple layers, in the direction from top to bottom, a steaming plate can be placed on the inner steamer and / or the outer steamer of the second layer, and the inner steamer is taken out from the first-layer steamer assembly. The first-layer steamer assembly will not block the upper part of the steaming plate, and there is a large space above the steaming plate, so as to facilitate placing food with a larger volume on the steaming plate. By the above method, the use flexibility of the cooking device can be improved, so as to facilitate cooking different types of food.

[0033] In some technical solutions, optionally, the steaming plate and the communication holes are misaligned.

[0034] The steaming plate and the communication holes are misaligned to prevent the steaming plate from blocking the communication holes and ensure that the communication holes can allow steam to flow smoothly.

[0035] In some technical solutions, optionally, between two adjacent layers of steamer assemblies, the steaming plate and the inner steamer in the upper-layer steamer assembly are arranged at intervals to allow steam to flow between the two adjacent inner steamers.

[0036] When multiple layers of steamer assemblies are stacked on the heating assembly, if a steaming plate is provided in a certain layer of steamer assembly, the steaming plate is located below the inner steamer in the upper-layer steamer assembly, and the steaming plate and the inner steamer in the upper layer are arranged at intervals, that is, the bottom of the inner steamer is higher than the bottom of the outer steamer, and a height difference is formed between the bottom of the inner steamer and the bottom of the outer steamer, so as to form a space for steam to flow between the steaming plate and the inner steamer in the upper layer. Steam can flow through the bottom of one layer of the inner steamer and the top of the next layer of the inner steamer, so that the bottom and the top of the inner steamer can be heated by steam, ensuring the temperature uniformity of the top and the bottom of the inner steamer and reducing the generation of condensed water inside the inner steamer.

[0037] In some technical solutions, optionally, in the stacking direction of the multiple layers of steamer assemblies, the distance between the steaming plate and the bottom of the inner steamer in the upper layer is L1, and the height difference from the top to the bottom of the inner steamer is L2, and L1 < L2.

[0038] There is a small distance between the steaming plate and the bottom of the inner steamer in the upper layer. A small amount of steam is located between two adjacent inner steamers. The height difference from the top to the bottom of the inner steamer is large, and a large amount of steam can cover the side of the inner steamer, which is beneficial to improving the heating efficiency of the food ingredients inside the inner steamer.

[0039] In some technical solutions, optionally, the distance between the side of the inner steamer and the outer steamer is L3, and L3 > L1.

[0040] There is a relatively large gap between the side of the inner steamer and the outer steamer, and a relatively small gap between the steaming plate and the bottom of the upper-layer inner steamer, which is conducive to the movement of steam towards the bottom of the inner steamer, and thus conducive to reducing the formation of condensed water.

[0041] In some technical solutions, optionally, a plurality of mounting grooves are provided at the top of the inner steamer; the cooking device further includes: a handle, and the handle is mounted on at least a part of the mounting grooves, and the handle can extend out or be received in the mounting grooves.

[0042] The inner steamer is lapped on the outer steamer. When the inner steamer needs to be taken out of the outer steamer, it is difficult for the user to lift the edge of the inner steamer, resulting in a difficult process of taking out the inner steamer.

[0043] In this solution, a handle is installed at the top of the inner steamer. When the inner steamer needs to be taken out of the outer steamer, the user can lift the handle, thus facilitating the taking out of the inner steamer.

[0044] A plurality of mounting grooves are provided at the top of the inner steamer, and a handle is installed on the inner wall of a part of the mounting grooves. The handle can be pulled out of the mounting groove or the handle can be received in the mounting groove. For example, when the inner steamer needs to be taken out, the user pulls the handle out of the mounting groove, so that the handle can be lifted. When the handle is not needed, the handle is received in the mounting groove to avoid interference between the handle and the steaming plate or interference between the handle and the upper-layer steamer assembly.

[0045] Exemplarily, if the number of mounting grooves is 4, the handle can be installed in 2 of the mounting grooves. When the structure for installing the handle in a part of the mounting grooves is damaged, the user can install the handle in other mounting grooves to provide backup use for the user.

[0046] Exemplarily, the handle is installed on the inner wall of the mounting groove through a snap structure.

[0047] In some technical solutions, optionally, a third step portion is provided at the circumferential edge of the steaming plate, and the third step portion is lapped on the first step portion and / or the second step portion.

[0048] The steaming plate needs to be placed on the inner steamer and / or the outer steamer. In order to prevent the steaming plate from moving, a third step portion is provided at the circumferential edge of the steaming plate in this solution. When the third step portion is lapped on the first step portion, the first step portion limits the third step portion, thereby restricting the relative movement of the steaming plate with respect to the inner steamer and ensuring the stability of the food placed on the steaming plate.

[0049] Similarly, when the third step portion is lapped on the second step portion, the second step portion can also limit the third step portion, thereby restricting the relative movement of the steaming plate with respect to the outer steamer.

[0050] Alternatively, a part of the third stepped portion can be set to overlap on the first stepped portion, and another part of the third stepped portion can be set to overlap on the second stepped portion, so as to limit the third stepped portion by the first stepped portion and the second stepped portion simultaneously.

[0051] In some technical solutions, optionally, the number of layers of the steamer assembly is N1, where N1 satisfies 0 < N1 ≤ 10; and / or the number of ventilation holes on one steaming plate is N2, where N2 satisfies 0 < N2 ≤ 120; and / or the number of steaming plates is N3, where N3 satisfies 0 < N3 ≤ 5.

[0052] The steamer assembly has multiple layers, and the user can select between 1 layer and 10 layers according to the usage requirements to meet the user's cooking needs.

[0053] On one steaming plate, a plurality of ventilation holes are provided. If the number of ventilation holes is too large, the structural stability of the steaming plate will be reduced. In this solution, it is defined that the number N2 of ventilation holes satisfies 0 < N2 ≤ 120, which can ensure the ventilation effect of the steaming plate and also ensure the structural stability of the steaming plate.

[0054] The number of steaming plates is between 1 and 5, and the user can select the number of steaming plates according to the usage requirements, which is convenient for the user to cook.

[0055] In some technical solutions, optionally, the steaming plate includes: a first steaming plate portion, on which ventilation holes are provided; a second steaming plate portion, connected to the first steaming plate portion, and the second steaming plate portion is distributed along the circumferential direction of the first steaming plate portion.

[0056] The outermost circumference of the steaming plate serves as the second steaming plate portion, and the middle part of the steaming plate serves as the first steaming plate portion. Ventilation holes are provided on the first steaming plate portion, and no ventilation holes are provided on the second steaming plate portion. Therefore, ventilation holes are provided in the middle of the steaming plate, and no ventilation holes are provided at the position close to the edge of the steaming plate, so that the ventilation holes are far away from the communication holes, and the steam at the communication holes is not likely to directly flow into the inner pot through the ventilation holes, making the steam circulate stably in the cooking device.

[0057] In some technical solutions, optionally, the heating assembly is provided with a heating cavity, and the heating cavity is connected to the steam channel. The heating cavity includes a cavity bottom wall, a first arc transition section, and a first side wall, and the cavity bottom wall and the first side wall are connected by the first arc transition section; and / or the cavity includes a cavity top wall, a second arc transition section, and a second side wall, and the cavity top wall and the second side wall are connected by the second arc transition section.

[0058] A first arc transition section is provided between the bottom of the heating cavity and the side part of the heating cavity. The first arc transition section plays a role in guiding the steam, and the steam flowing into the heating cavity can flow smoothly along the first arc transition section, ensuring the flow stability of the steam in the heating cavity.

[0059] A second arc transition section is provided between the top of the cavity and the side of the cavity. The second arc transition section guides the steam, and the steam flowing into the cavity can flow smoothly along the second arc transition section, ensuring the flow stability of the steam in the cavity.

[0060] By providing an arc transition structure in the cavity and the heating cavity, it is beneficial to improve the circulation effect of the steam in the cooking device.

Detailed implementation manners

[0074] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0075] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0076] The following refers to Figures 1 to 9 Describe a cooking device provided according to some embodiments of the present utility model.

[0077] Combined with Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown in

[0078] In the embodiment of the present utility model, a cooking device 100 is proposed, which includes: a heating component 110, a steamer assembly 120 and a cover body 130. The steamer assembly 120 is arranged on the heating component 110. The steamer assembly 120 includes an inner steamer 121 and an outer steamer 122. The inner steamer 121 is arranged inside the outer steamer 122. A steam channel 123 is provided between the inner steamer 121 and the outer steamer 122. At least a part of the steam channel 123 is located at the bottom of the inner steamer 121. The heating component 110 is used to supply steam into the steam channel 123. The cover body 130 is covered on the steamer assembly 120. A cavity 131 is formed between the cover body 130 and the steamer assembly 120. The cavity 131 is communicated with the steam channel 123.

[0079] The steamer assembly 120 includes an inner steamer 121 and an outer steamer 122. The inner steamer 121 is fixed on the outer steamer 122, and the inner steamer 121 is used for steaming food. A steam channel 123 is formed between the inner steamer 121 and the outer steamer 122. The heating assembly 110 is communicated with the steam channel 123, so that the steam generated by the heating assembly 110 can flow into the steam channel 123.

[0080] The cover 130 is buckled on the steamer assembly 120, so that a cavity 131 is formed between the cover 130 and the steamer assembly 120. The cavity 131 is communicated with the steam channel 123. Therefore, the steam in the steam channel 123 can flow into the cavity 131. The heating assembly 110, the steam channel 123 and the cavity 131 are communicated in sequence, so that the steam can flow among the heating assembly 110, the steam channel 123 and the cavity 131. When the steam content in the cavity 131 is relatively high, a part of the steam can flow back into the steam channel 123, so that a circulating flow of steam is formed among the heating assembly 110, the steam channel 123 and the cavity 131 ( Figure 2 The arrow in the figure is used to indicate the steam flow direction).

[0081] At least a part of the steam channel 123 is located at the bottom of the inner steamer 121, and the cavity 131 is located at the top of the inner steamer 121. Therefore, steam flows through both the top and the bottom of the inner steamer 121. Under the circulating action of the steam, the temperatures of the steam at various parts among the heating assembly 110, the steam channel 123 and the cavity 131 are basically the same, so that the temperatures of the top and the bottom of the inner steamer 121 are basically consistent, and there is a small temperature difference between the top and the bottom of the inner steamer 121. The steam cannot condense near the inner steamer 121, thereby reducing the condensed water on the food and ensuring the cooking taste of the food.

[0082] Compared with the straight-up-and-down perforated steamer in the related art, during the cooking process of the cooking device 100 in this solution, the steam will not directly pass through the inner steamer 121, thereby avoiding the steam directly passing through the food. Usually, the steam contains more moisture. By avoiding the steam passing through the food, the probability of the moisture contacting the food can be reduced, thereby reducing the moisture accumulated on the food surface and further ensuring the cooking taste of the food.

[0083] The air temperatures at the bottom and the upper part of the inner steamer 121 reach the same temperature due to the steam continuously generated by the heating assembly 110 and the "surrounding" steam inside the cover 130 and the heating assembly 110, so that the temperature difference is small and the steam cannot condense, solving the problem of the long time with water during steaming and realizing waterless steaming.

[0084] The inner steamer 121 is used for steaming, and the bottom is sealed.

[0085] Exemplarily, the heating component 110 heats the water inside it in the form of a heating tube or other heating means.

[0086] In this embodiment, the bottom of the outer steamer 122 has an open structure. In other embodiments, a plurality of through holes may also be provided at the bottom of the outer steamer 122.

[0087] Combined with Figure 2 、 Figure 3 and Figure 7 As shown in

[0088] In some embodiments, optionally, the outer steamer 122 includes a top wall 124, and a plurality of communication holes 125 are provided on the top wall 124. The steam channel 123 and the cavity 131 are connected through the communication holes 125.

[0089] A plurality of communication holes 125 are provided at the top of the outer steamer 122. The steam in the steam channel 123 can flow through the communication holes 125 to the cavity 131, and the steam in the cavity 131 can also flow back into the steam channel 123 through the communication holes 125.

[0090] Combined with Figure 2 、 Figure 3 and Figure 7 As shown in Figure 7 the arrow direction at C in

[0091] In some embodiments, optionally, an opening 126 is provided at the top of the outer steamer 122, and the top wall 124 is distributed along the circumference of the opening 126 (

[0092] The top wall 124 of the outer steamer 122 is distributed along the circumference of the opening 126, so that a plurality of communication holes 125 can be distributed in the circumferential direction of the inner steamer 121. The plurality of communication holes 125 can allow steam to pass through simultaneously, so that steam flows through the entire circumference of the inner steamer 121, which is beneficial to improving the uniform heating of the inner steamer 121, can not only improve the cooking effect on food, but also avoid the generation of condensed water.

[0093] As Figure 7 shown, in some embodiments, optionally, the top wall 124 is inclined towards the opening 126.

[0094] The top wall 124 in this solution is a structure with an inclined setting. Among them, the top wall 124 is inclined towards the opening 126, and the top wall 124 is an annular structure. Therefore, the top wall 124 forms a form with a higher outer ring and a lower inner ring.

[0095] The steam in the steam passage 123 flows through the opening 126 into the cavity 131. Since the top wall 124 is inclined inward, the steam flowing out of the steam passage 123 will also converge above the middle of the inner steamer 121, making the top temperature of the inner steamer 121 higher. This method can further reduce the temperature difference between the top and the bottom of the inner steamer 121, further improve the temperature uniformity at various parts of the inner steamer 121, and reduce the condensed water generated on the food surface.

[0096] In some embodiments, optionally, the top of the inner steamer 121 is circumferentially attached to the top of the outer steamer 122.

[0097] When the inner steamer 121 is placed on the outer steamer 122, the top of the inner steamer 121 is hermetically attached to the top of the outer steamer 122, and steam is not likely to flow along the position where the inner steamer 121 and the outer steamer 122 are attached to each other. Most of the steam between the cavity 131 and the steam passage 123 circulates through the communication holes 125. The plurality of communication holes 125 are distributed around the inner steamer 121. By circulating steam through the communication holes 125, the uniformity of steam distribution around the inner steamer 121 can be improved. If there is local air leakage at the attachment position of the inner steamer 121 and the outer steamer 122, it is easy to cause the problem of steam concentration at local positions of the inner steamer 121. Therefore, through the above method, the circumferential uniform heating of the inner steamer 121 is ensured.

[0098] Combined Figure 2 and Figure 3 shown, in some embodiments, optionally, a first step portion 127 is provided at the top edge of the inner steamer 121, and a second step portion 128 is provided on the top wall 124. The first step portion 127 is lapped on the second step portion 128.

[0099] The top edge of the inner steamer 121 overlaps the top edge of the outer steamer 122. In this solution, a first stepped portion 127 is formed on the top edge of the inner steamer 121, and the first stepped portion 127 is distributed along the circumferential direction of the inner steamer 121. A second stepped portion 128 is formed on the top wall 124 of the outer steamer 122, and the second stepped portion 128 is distributed along the circumferential direction of the outer steamer 122.

[0100] When the inner steamer 121 is placed in the outer steamer 122, the first stepped portion 127 overlaps the second stepped portion 128. Both the first stepped portion 127 and the second stepped portion 128 are stepped structures. Therefore, there are multiple vertical and horizontal fitting structures between the first stepped portion 127 and the second stepped portion 128, thereby increasing the contact area between the first stepped portion 127 and the second stepped portion 128, which is beneficial to improving the sealing effect between the inner steamer 121 and the outer steamer 122, preventing steam from flowing through the position where the inner steamer 121 and the outer steamer 122 are in contact with each other, and ensuring the circumferential heat uniformity of the inner steamer 121.

[0101] When the first stepped portion 127 and the second stepped portion 128 overlap each other, the second stepped portion 128 can limit the first stepped portion 127, and the first stepped portion 127 is not easily displaced relative to the second stepped portion 128, thereby ensuring the placement stability of the inner steamer 121 on the outer steamer 122 and preventing the inner steamer 121 from shaking relative to the outer steamer 122.

[0102] In other embodiments, the sealing structure between the inner steamer 121 and the outer steamer 122 is not limited to the first stepped portion 127 and the second stepped portion 128. For example, the overlapping position between the inner steamer 121 and the outer steamer 122 can be sealed by a sealing gasket.

[0103] Combined Figure 2 、 Figure 3 and Figure 5 As shown in, in some embodiments, optionally, the number of the steamer assemblies 120 is at least two layers, and the outer steamer 122 in one layer of the steamer assembly 120 overlaps the outer steamer 122 in the adjacent steamer assembly 120.

[0104] The cooking device 100 includes at least two layers of steamer assemblies 120. The user can, according to their cooking needs, place one layer of the steamer assembly 120 on the heating assembly 110, or place multiple layers of the steamer assemblies 120 on the heating assembly 110.

[0105] When multiple layers of the steamer assemblies 120 are stacked on the heating assembly 110, the outer steamer 122 in one layer of the steamer assembly 120 is placed on the outer steamer 122 in the next lower layer of the steamer assembly 120, thereby realizing the stacking of multiple layers of the steamer assemblies 120.

[0106] When the multi - layer steamer assemblies 120 are stacked, since the communication holes 125 are vertically formed, the steam channels 123 in adjacent two - layer steamer assemblies 120 are interconnected. During the cooking process, the steam generated by the heating assembly 110 first flows into the steam channel 123 of the lowermost steamer assembly 120, and then the steam successively circulates upward into the steam channels 123 of the upper layers, and the steam in the steam channel 123 of the uppermost layer flows into the cavity 131.

[0107] The relative setting, shape, and angle of the communication holes 125 in the multi - layer steamer assemblies 120 can be changed, thereby forming a spiral steam rising form such as "tornado steaming".

[0108] Combined with Figure 2 、 Figure 3 、 Figure 5 and Figure 9 As shown in

[0109] In some embodiments, optionally, at least one layer of the steamer assembly 120 further includes: a steaming plate 129, the steaming plate 129 is lapped on the inner steamer 121 and / or the outer steamer 122, the steaming plate 129 covers the opening 126, and the steaming plate 129 is provided with ventilation holes 1291, and the ventilation holes 1291 are communicated with the inner cavity of the inner steamer 121, so that steam can flow into the inner cavity of the inner steamer 121 through the ventilation holes 1291.

[0110] The steaming plate 129 can be placed on the inner steamer 121 and / or the outer steamer 122, and ingredients can be placed on the steaming plate 129. The ventilation holes 1291 are provided on the steaming plate 129, and steam can flow into the interior of the inner steamer 121 through the ventilation holes 1291, thereby heating the ingredients in the inner steamer 121.

[0111] In some embodiments, optionally, the steaming plate 129 and the communication holes 125 are staggeredly distributed.

[0112] The steaming plate 129 and the communication holes 125 are misaligned to prevent the steaming plate 129 from blocking the communication holes 125, ensuring that the communication holes 125 allow steam to flow smoothly.

[0113] Such as Figure 2 shown, in some embodiments, optionally, in adjacent two layers of the steamer assemblies 120, the steaming plate 129 and the inner steamer 121 in the upper-layer steamer assembly 120 are arranged at intervals, so that steam can flow between the adjacent two layers of inner steamers 121.

[0114] When multiple layers of steamer assemblies 120 are stacked on the heating assembly 110, if a steaming plate 129 is provided in a certain layer of the steamer assembly 120, the steaming plate 129 is located below the inner steamer 121 in the upper-layer steamer assembly 120, and the steaming plate 129 and the inner steamer 121 in the upper layer are arranged at intervals, that is, the bottom of the inner steamer 121 is higher than the bottom of the outer steamer 122, and a height difference is formed between the bottom of the inner steamer 121 and the bottom of the outer steamer 122, so as to form a space for steam to flow between the steaming plate 129 and the inner steamer 121 in the upper layer. Steam can flow through the bottom of one layer of the inner steamer 121 and the top of the lower-layer inner steamer 121, so that the bottom and the top of the inner steamer 121 can be heated by steam, ensuring the temperature uniformity of the top and the bottom of the inner steamer 121 and reducing the generation of condensed water inside the inner steamer 121.

[0115] In some embodiments, optionally, in the stacking direction of the multiple layers of steamer assemblies 120 ( Figure 2 the direction pointed by the arrow at B), the distance between the steaming plate and the bottom of the inner steamer 121 in the upper layer is L1, and the height difference from the top to the bottom of the inner steamer 121 is L2, and L1 < L2.

[0116] The distance between the steaming plate 129 and the bottom of the inner steamer 121 in the upper layer is small, a small amount of steam is located between the adjacent two layers of inner steamers 121, and the height difference from the top to the bottom of the inner steamer 121 is large. A large amount of steam can cover the side of the inner steamer 121, which is beneficial to improving the heating efficiency of the ingredients inside the inner steamer 121.

[0117] In some embodiments, optionally, the distance between the side of the inner steamer 121 and the outer steamer 122 is L3, and L3 > L1.

[0118] The distance between the side of the inner steamer 121 and the outer steamer 122 is large, and the distance between the steaming plate 129 and the bottom of the inner steamer 121 in the upper layer is small, which is beneficial to the movement of steam to the bottom of the inner steamer 121, and further beneficial to reducing the formation of condensed water.

[0119] Combined with Figure 6And Figure 8 As shown in Figure 8 , in some embodiments, optionally, a plurality of mounting grooves 1211 are provided at the top of the inner steamer 121. The cooking device 100 further includes: a handle 140, and at least a part of the mounting grooves 1211 are mounted with the handle 140, and the handle 140 can be extended or received into the mounting groove 1211.

[0120] The inner steamer 121 is lapped on the outer steamer 122. When the inner steamer 121 needs to be taken out of the outer steamer 122, it is difficult for the user to lift the edge of the inner steamer 121, resulting in a difficult process of taking out the inner steamer 121.

[0121] In this solution, a handle 140 is installed on the top of the inner steamer 121. When the inner steamer 121 needs to be taken out of the outer steamer 122, the user can lift the handle 140, thus facilitating the taking out of the inner steamer 121.

[0122] A plurality of mounting grooves 1211 are provided at the top of the inner steamer 121, and the handle 140 is installed on the inner wall of a part of the mounting grooves 1211. The handle 140 can be pulled out of the mounting groove 1211 or the handle 140 can be received in the mounting groove 1211. For example, when the inner steamer 121 needs to be taken out, the user pulls the handle 140 out of the mounting groove 1211, so that the handle 140 can be lifted. When the handle 140 is not needed, the handle 140 is received in the mounting groove 1211 to avoid interference between the handle 140 and the steaming plate 129 or interference between the handle 140 and the upper steamer assembly 120.

[0123] Exemplarily, if the number of the mounting grooves 1211 is 4, the handle 140 can be installed in 2 of the mounting grooves 1211. When the structure for installing the handle 140 in a part of the mounting grooves 1211 is damaged, the user can install the handle 140 in other mounting grooves 1211 for backup use by the user.

[0124] Exemplarily, the handle 140 is installed on the inner wall of the mounting groove 1211 through a snap structure.

[0125] Exemplarily, in this embodiment, the handle 140 is a hardware handle, and the hardware handle can rotate relative to the mounting groove 1211, so as to realize the receiving and taking out of the hardware handle.

[0126] Combined with Figure 2 And Figure 3 As shown in Figure 3 , in some embodiments, optionally, a third step portion 1292 is provided at the circumferential edge of the steaming plate 129, and the third step portion 1292 is lapped on the first step portion 127 and / or the second step portion 128.

[0127] The steaming plate 129 needs to be placed on the inner steaming pot 121 and / or the outer steaming pot 122. To prevent the steaming plate 129 from shifting, in this solution, a third stepped portion 1292 is provided at the circumferential edge of the steaming plate 129. When the third stepped portion 1292 is lapped on the first stepped portion 127, the first stepped portion 127 limits the third stepped portion 1292, thereby restricting the relative movement of the steaming plate 129 with respect to the inner steaming pot 121 and ensuring the stability of the food placed on the steaming plate 129.

[0128] Similarly, when the third stepped portion 1292 is lapped on the second stepped portion 128, the second stepped portion 128 can also limit the third stepped portion 1292, thereby restricting the relative movement of the steaming plate 129 with respect to the outer steaming pot 122.

[0129] Alternatively, a part of the third stepped portion 1292 can be lapped on the first stepped portion 127, and another part of the third stepped portion 1292 can be lapped on the second stepped portion 128, and the first stepped portion 127 and the second stepped portion 128 limit the third stepped portion 1292 simultaneously.

[0130] In some embodiments, optionally, the number of layers of the steamer assembly 120 is N1, where N1 satisfies 0 < N1 ≤ 10. And / or the number of ventilation holes 1291 on one steaming plate 129 is N2, where N2 satisfies 0 < N2 ≤ 120. And / or the number of steaming plates 129 is N3, where N3 satisfies 0 < N3 ≤ 5.

[0131] The steamer assembly 120 has multiple layers, and users can select between 1 layer and 10 layers according to their usage requirements to meet the cooking needs of users. Exemplarily, the number of layers of the steamer assembly 120 is 1 layer, 5 layers or 10 layers.

[0132] On one steaming plate 129, a plurality of ventilation holes 1291 are provided. If the number of ventilation holes 1291 is too large, the structural stability of the steaming plate 129 will be reduced. In this solution, it is defined that the number N2 of ventilation holes 1291 satisfies 0 < N2 ≤ 120, which can ensure the ventilation effect of the steaming plate 129 and also ensure the structural stability of the steaming plate 129. Exemplarily, the number of ventilation holes 1291 on one steaming plate 129 is 5, 10, 50, 100 or 120.

[0133] The number of steaming plates 129 is between 1 and 5, and users can select the number of steaming plates 129 according to their usage requirements, which is convenient for users to cook. Exemplarily, the number of steaming plates 129 is 1, 3 or 5.

[0134] After setting the above parameters, during the user's use, the situation of a large amount of condensate water in the steaming layer during previous steaming of food is greatly reduced, and the thermal efficiency of the steam is improved by the surrounding steaming method.

[0135] Such asFigure 9 As shown, in some embodiments, optionally, the steaming plate 129 includes a first steaming plate portion 1293 and a second steaming plate portion 1294.

[0136] The outer perimeter of the steaming plate 129 serves as the second steaming plate portion 1294, and the middle part of the steaming plate 129 serves as the first steaming plate portion 1293. An air vent 1291 is provided on the first steaming plate portion 1293, and no air vent 1291 is provided on the second steaming plate portion 1294. Therefore, air vents 1291 are provided in the middle part of the steaming plate 129, and no air vents 1291 are provided at the positions near the edge of the steaming plate 129, so that the air vents 1291 are far away from the communication holes 125, and the steam at the communication holes 125 is not likely to directly flow into the inner pot through the air vents 1291, enabling the steam to circulate stably in the cooking device 100.

[0137] As Figure 2 shown, in some embodiments, optionally, the heating assembly 110 is provided with a heating cavity 111, and the heating cavity 111 is communicated with the steam channel 123. The heating cavity 111 includes a cavity bottom wall 112, a first arc transition section 113, and a first side wall 114. The cavity bottom wall 112 and the first side wall 114 are connected by the first arc transition section 113.

[0138] And / or, the cavity 131 includes a cavity top wall 132, a second arc transition section 133, and a second side wall 134. The cavity top wall 132 and the second side wall 134 are connected by the second arc transition section 133.

[0139] A first arc transition section 113 is provided between the bottom of the heating cavity 111 and the side part of the heating cavity 111. The first arc transition section 113 guides the steam. The steam flowing into the heating cavity 111 can flow smoothly along the first arc transition section 113, ensuring the flow stability of the steam in the heating cavity 111.

[0140] A second arc transition section 133 is provided between the top of the cavity 131 and the side part of the cavity 131. The second arc transition section 133 guides the steam. The steam flowing into the cavity 131 can flow smoothly along the second arc transition section 133, ensuring the flow stability of the steam in the cavity 131.

[0141] By providing arc transition structures in the cavity 131 and the heating cavity 111, it is beneficial to improve the circulation effect of the steam in the cooking device 100.

[0142] Part of the structures of the cover body 130 and the heating assembly 110 are designed in an arc shape to enable the steam to "circulate" and form a "circular track" - type steam.
