[0007] Each steam generating assembly can work independently, different power can be set for each steam generating assembly to operate according to different cooking requirements, or the operation time of each steam generating assembly is different. For example, the food in the first cooking cavity needs to be heated quickly, and the food in the second cooking cavity does not need to be heated quickly, so the steam generating assembly corresponding to the first cooking cavity can be operated at a large power to generate steam quickly. The steam generating assembly corresponding to the second cooking cavity is operated at a small power to reduce the steam generation speed.

Moreover, the sleeved arrangement can also reduce the occupied space of the at least two steam generation assemblies, and the space utilization rate is improved.

[0012] In addition, the cooking equipment in the above technical solution according to the utility model can also have the following additional technical features.

[0020] The first steam generating cylinder and the second steam generating cylinder are both provided with a heating element, and the steam generated by the first steam generating cylinder and the second steam generating cylinder is independent of each other, so that the first steam generating cylinder and the second steam generating cylinder are respectively connected to different cooking cavities, thereby enabling different cooking cavities to be heated separately.

[0021] The cross-sectional area of at least a part of the first steam generating cylinder increases, so that the steam can flow slowly and uniformly to the cooking cavity, the steam can be efficiently exchanged with the food material, and the cooking effect on the food material is improved.

[0022] In some technical solutions, optionally, a steam inner cavity is formed between the first steam generating cylinder and the second steam generating cylinder, and the cross-sectional area of at least a part of the steam inner cavity decreases from the bottom of the second steam generating cylinder to the top of the second steam generating cylinder.

[0023] The second steam generating cylinder is located outside, and the heat in the second steam generating cylinder is more likely to be lost, so that a part of the second steam generating cylinder is provided with a smaller cross-sectional area, the flow speed of the steam in the second steam generating cylinder is improved, the steam quickly flows into the cooking cavity, and the heat loss of the steam is reduced.

[0024] In some technical solutions, optionally, the minimum cross-sectional area of the first steam generating cylinder is greater than the maximum cross-sectional area of the steam inner cavity.

[0025] The cross-sectional area of the first steam generating cylinder is large, so that the steam can uniformly flow into the cooking cavity, the cross-sectional area of the steam inner cavity is small, so that the steam can quickly flow into the cooking cavity. According to the arrangement mode of the first steam generating cylinder and the second steam generating cylinder inside and outside, the cross-sectional area of the outer side channel is small, and the cross-sectional area of the inner side channel is large, which can not only ensure the heating effect, but also reduce the heat loss.

[0032] The water tank can supply water to the steam generating component, for example, a hole is formed in the side of the steam generating component, so as to avoid the water in the steam generating component from being dried out and save the workload of the user to frequently supply water to the steam generating component.

[0033] In some embodiments, one steam generating assembly located at the outermost layer is connected to the cooking cavity through the water tank.

[0034] The steam generated by the steam generating assembly at the outermost layer first flows into the water tank and then flows into the cooking cavity, and the water tank is used as a flow channel for the steam, so that a separate channel does not need to be arranged for the steam generating assembly at the outermost layer, which is beneficial to simplify the structure of the product.

[0035] In some embodiments, a flow guide channel is arranged on the base, and at least one part of the steam generating assemblies are connected to the cooking cavity through the flow guide channel, and the flow guide channel is used to separate the steam flowing out of adjacent two steam generating assemblies.

[0036] The flow guide channel can guide the steam, so as to ensure that the steam generated by the steam generating assembly flows stably into the cooking cavity.

[0039] In some embodiments, the top of the innermost steam generation assembly is connected to the housing.

[0040] The top of the innermost steam generation assembly is connected to the bottom of the housing, so that the innermost steam generation assembly is integrally arranged with the housing, reducing the number of parts inside the cooking device and facilitating the disassembly and assembly of the cooking device by the user.

[0041] In some embodiments, the steam in the innermost steam generation assembly is discharged from the top.

[0042] The steam generated by the innermost steam generation assembly is discharged from the top, and the top of the innermost steam generation assembly is connected to the bottom of the housing. Therefore, the innermost steam generation assembly and the housing can share a part of the opening, and the opening is used for steam flow. Therefore, it is not necessary to provide two sets of openings for the innermost steam generation assembly and the housing, which is beneficial to reduce the processing difficulty of the product.

[0043] In some embodiments, the housing includes a partition plate, the partition plate serving as a cavity bottom wall of the cooking cavity, the partition plate having steam holes, and any two cooking cavities being in communication with the steam generation assembly through different steam holes.

[0044] Any two cooking cavities form independent steam transmission paths with the steam generation assembly, that is, each cooking cavity can directly receive steam supply from the steam generation assembly without passing through other cooking cavities.

[0045] Since each cooking cavity is in communication with the steam generation assembly through an independent steam hole, the steam does not interfere with each other during transmission, thereby effectively avoiding the problem of flavor mixing between foods in different cooking cavities, and providing a more pure cooking experience for the user.

[0046] Each cooking cavity can directly receive steam from the steam generation assembly without "transferring" through other cooking cavities, improving the utilization rate of the steam, and ensuring that the cooking cavities far away from the steam generation assembly can obtain sufficient amount of steam, thereby ensuring the uniformity and efficiency of cooking.

[0047] In some embodiments, optionally, the inner wall of the cooking cavity is provided with at least two air inlet sub-zones, each air inlet sub-zone is provided with a plurality of steam holes, and the spacing between the at least two air inlet sub-zones and the side of the shell increases sequentially.

[0048] The inner wall of the cooking cavity is provided with a plurality of air inlet sub-zones for guiding steam into the cooking cavity. Each air inlet sub-zone is provided with a plurality of steam holes. In one air inlet sub-zone, the plurality of steam holes are distributed along the circumference of the cooking device. The spacing between the plurality of air inlet sub-zones and the side of the shell increases sequentially. In order to avoid the cross of steam between different cooking cavities, the spacing between the air inlet sub-zones and the side of the shell increases sequentially. This spacing design ensures that the cooking cavities located in the lower layer have channel space, and these channel spaces are physically isolated from each other.

[0049] In some embodiments, optionally, the shell further comprises a baffle, at least a portion of the cooking cavity is provided with the baffle, and the steam generated by adjacent two steam generation assemblies is separated in the cooking cavity by the baffle.

[0050] The cooking cavity is provided with a gear, and the baffle can separate the steam flowing to different cooking cavities to avoid the problem of steam cross contamination.

[0051] In some embodiments, optionally, the direction from the bottom of the steam generation assembly to the top of the steam generation assembly is the first direction, and the exhaust positions of the at least two steam generation assemblies are arranged along the first direction sequentially; in the plurality of air inlet sub-zones, the direction from the innermost air inlet sub-zone to the outermost air inlet sub-zone is the second direction.

[0052] In the second direction, the steam holes in the at least two air inlet sub-zones are sequentially communicated with the at least two steam generation assemblies in the first direction.

[0053] The first direction refers to the direction from bottom to top, and the second direction refers to the direction from inside to outside. The steam generation assembly is provided with a steam outlet, and in the at least two steam generation assemblies, the steam outlets are distributed along the first direction sequentially. The uppermost steam outlet is communicated with the innermost air inlet sub-zone, the second steam outlet from the top is communicated with the second air inlet sub-zone from the inside, and so on. The lowermost steam outlet is communicated with the outermost air inlet sub-zone. In this way, the plurality of steam outlets can be neatly communicated with the plurality of air inlet sub-zones, avoiding the cross of the connection channels between the plurality of steam outlets and the plurality of air inlet sub-zones, thereby facilitating the processing of the connection channels between the steam outlets and the air inlet sub-zones.

DETAILED DESCRIPTION

[0061] In order to more clearly understand the above-mentioned purposes, features and advantages of the present utility model, the present utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0062] In the following description, a lot of specific details are set forth in order to give a thorough understanding of 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.

[0063] The following refers to Figures 1 to 3 A cooking device provided according to some embodiments of the present utility model is described.

[0064] In combination with Figure 1 and Figure 2 It is shown that in some embodiments of the present utility model, a cooking device 100 is proposed, comprising a base 110, at least two steam generating assemblies 190 and a shell 140, the at least two steam generating assemblies 190 are arranged in the base 110, and the at least two steam generating assemblies 190 are arranged in each other. The shell 140 is arranged on the base 110, a plurality of cooking cavities 141 are arranged in the shell 140, and different cooking cavities 141 are communicated with different steam generating assemblies 190.

[0065] The steam generation assembly 190 can heat water to generate steam, and the steam flow discharged from the steam generation assembly 190 flows to the cooking cavity 141, thereby heating the food material in the cooking cavity 141. Each steam generation assembly 190 is in communication with a corresponding cooking cavity 141, so that the steam generated by one steam generation assembly 190 can only enter the corresponding cooking cavity 141.

[0066] Each steam generation assembly 190 can work independently, and can be set to operate at different powers or for different lengths of time according to different cooking requirements. For example, if the food material in the first cooking cavity 141 needs to be heated quickly and the food material in the second cooking cavity 141 does not need to be heated quickly, the steam generation assembly 190 corresponding to the first cooking cavity 141 can be operated at a relatively large power to quickly generate steam. The steam generation assembly 190 corresponding to the second cooking cavity 141 can be operated at a relatively small power to reduce the steam generation speed.

[0067] The plurality of steam generation assemblies 190 are independent of each other and do not interfere with each other. The operation parameters of different steam generation assemblies 190 can be controlled to output steam at different temperatures, respectively. The heating time of different steam generation assemblies 190 can also be controlled to start or stop heating.

[0068] Through the above control mode, independent cooking of the food materials in the plurality of cooking cavities 141 can be realized. If the food material in one cooking cavity 141 is cooked, the food material does not need to be taken out, and only the steam generation assembly 190 corresponding to the food material needs to be stopped to avoid interrupting the cooking of other food materials due to taking out of the food material, thereby improving the user convenience of the cooking device 100.

[0069] In addition, since different steam generation assemblies 190 can work independently, the heating power and heating time of different steam generation assemblies 190 can be used to synchronize the cooking of the food materials in the plurality of cooking cavities 141.

[0070] The at least two steam generation assemblies 190 are sleeved with each other, so that adjacent two steam generation assemblies 190 can heat each other to realize the heat preservation function and avoid heat loss. In addition, the sleeving manner can also reduce the occupied space of the at least two steam generation assemblies, thereby improving the space utilization.

[0071] In combination with Figure 1 and Figure 2As shown, in some embodiments, optionally, at least a portion of one steam generating assembly 190 is located in an adjacent steam generating assembly 190, and the interiors of the two adjacent steam generating assemblies 190 are independent of each other.

[0072] In this scheme, by arranging at least two steam generating assemblies 190 in a nested relationship and making the steam generating assemblies 190 independent of each other, the problem of mixing steam at different temperatures is avoided, and the problem of odor in the cooking cavity 141 leaking through the steam generating assembly 190 is also avoided.

[0073] In some embodiments, optionally, steam in the steam generating assembly 190 is discharged from the top; or steam in a portion of the steam generating assembly 190 is discharged from the top, and steam in another portion of the steam generating assembly 190 is discharged from the side; or steam in the steam generating assembly 190 is discharged from the side, and the steam discharge positions on the at least two steam generating assemblies 190 are spaced apart in the height direction of the steam generating assembly 190 (arrow direction in H). Figure 1

[0074] The opening through which each steam generating assembly 190 discharges steam can be provided on the top or on the side. Alternatively, according to the processing size and the installation structure, the openings of a portion of the steam generating assemblies 190 can be provided on the top, and the openings of another portion of the steam generating assemblies 190 can be provided on the side.

[0075] In combination with Figure 1 and Figure 2 As shown, in some embodiments, optionally, the steam generating assembly 190 includes a steam generating cylinder 120 and a heating element 130, and in the two adjacent steam generating assemblies 190, at least a portion of one steam generating cylinder 120 is located in an adjacent steam generating cylinder 120, and the heating element 130 is arranged in the steam generating cylinder 120.

[0076] The heating element 130 can heat the water in the steam generating cylinder 120, and the heating elements 130 in different steam generating cylinders 120 work independently, and different heating elements 130 can be controlled to operate at different powers or for different lengths of time, so as to realize heating of different cooking cavities 141 by steam at different temperatures.

[0077] In combination with Figure 1 and Figure 2 As shown, in some embodiments, optionally, the two adjacent steam generating cylinders 120 include a first steam generating cylinder 150 and a second steam generating cylinder 160, at least a portion of the first steam generating cylinder 150 is located in the second steam generating cylinder 160, and from the bottom of the first steam generating cylinder 150 to the top of the first steam generating cylinder 150, at least a portion of the first steam generating cylinder 150 increases in cross-sectional area. ​

[0078] Heating elements 130 are provided in both the first steam generator 150 and the second steam generator 160. The steam generated by the first steam generator 150 and the second steam generator 160 are independent of each other. The first steam generator 150 and the second steam generator 160 are respectively connected to different cooking cavities 141, so that different cooking cavities 141 can be heated individually.

[0079] At least a portion of the cross-sectional area of ​​the first steam generator 150 is increased, allowing steam to flow slowly and evenly into the cooking chamber 141. The steam can then exchange heat efficiently with the food, which is beneficial for improving the cooking effect.

[0080] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, a steam cavity 170 is formed between the first steam generating cylinder 150 and the second steam generating cylinder 160, and the cross-sectional area of ​​at least a portion of the steam cavity 170 is reduced from the bottom to the top of the second steam generating cylinder 160.

[0081] The second steam generator 160 is located on the outside, and heat is more easily lost inside the second steam generator 160. Setting a smaller cross-sectional area for a part of the second steam generator 160 can increase the flow rate of steam inside the second steam generator 160, allowing steam to flow quickly into the cooking cavity 141 and reducing heat loss from the steam.

[0082] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the minimum cross-sectional area of ​​the first steam generator 150 is greater than the maximum cross-sectional area of ​​the steam cavity 170.

[0083] The first steam generator 150 has a larger cross-sectional area, allowing steam to flow evenly into the cooking chamber 141. The inner steam chamber 170 has a smaller cross-sectional area, allowing steam to flow quickly into the cooking chamber 141. Based on the arrangement of the first steam generator 150 and the second steam generator 160, the outer channel has a smaller cross-sectional area, while the inner channel has a larger cross-sectional area. This ensures effective heating while minimizing heat loss.

[0084] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, at least a portion of the sidewalls of the first steam generator 150 are inclined outward from the bottom to the top of the first steam generator 150.

[0085] At least a portion of the side wall of the first steam generating cylinder 150 is inclined, so that at least a portion of the cross-sectional area of the first steam generating cylinder 150 is increased, and at least a portion of the cross-sectional area of the steam inner cavity 170 is reduced, and the cross-sectional areas of the first steam generating cylinder 150 and the steam inner cavity 170 are changed, which is beneficial to simplify the structure of the product.

[0086] In combination Figure 1 and Figure 2 As shown in FIG. 1, in some embodiments, optionally, a first portion of the first steam generating cylinder 150 protrudes out of the second steam generating cylinder 160, and steam in the first steam generating cylinder 150 is discharged through the first portion.

[0087] A portion of the first steam generating cylinder 150 protrudes into the second steam generating cylinder 160, and another portion of the first steam generating cylinder 150 protrudes out of the second steam generating cylinder 160, and an air outlet structure is arranged on the other portion of the first steam generating cylinder 150, so that the air outlet position of the first steam generating cylinder 150 is not easily blocked by the second steam generating cylinder 160, thereby facilitating the air outlet structure on the first steam generating cylinder 150 to communicate with the cooking cavity 141.

[0088] In this scheme, the first steam generating cylinder 150 and the second steam generating cylinder 160 are concentrically arranged.

[0089] In combination Figure 1 and Figure 2 As shown in FIG. 1, in some embodiments, optionally, the cooking device 100 further comprises a water tank 200, the water tank 200 is arranged in the base 110, and the steam generating assembly 190 is arranged in the water tank 200, and the water tank 200 is used to supplement water to the steam generating assembly 190.

[0090] The water tank 200 can supplement water to the steam generating assembly, for example, a hole is formed in the side of the steam generating assembly, so as to avoid the water in the steam generating assembly from being dried out, and save the workload of the user to frequently supplement water to the steam generating assembly.

[0091] In combination Figure 1 and Figure 2 As shown in FIG. 1, in some embodiments, optionally, one steam generating assembly 190 located in the outermost layer communicates with the cooking cavity 141 through the water tank 200.

[0092] Steam generated by the steam generating assembly 190 in the outermost layer first flows into the water tank 200 and then flows into the cooking cavity 141, and the water tank 200 is used as a flow channel of the steam, and a separate channel does not need to be arranged for the steam generating assembly 190 in the outermost layer, which is beneficial to simplify the structure of the product.

[0093] In combination Figure 1 and Figure 2As shown, in some embodiments, the base 110 is optionally provided with a flow guide channel 111, and at least part of the steam generation assembly 190 is connected to the cooking cavity 141 through the flow guide channel 111. The flow guide channel 111 is used to separate the steam flowing out of two adjacent steam generation assemblies 190.

[0094] The flow guide channel 111 can guide the steam, ensuring that the steam generated by the steam generation assembly 190 flows stably into the cooking cavity 141. The flow guide channel 111 can also separate the steam generated by different steam generation assemblies 190, avoiding the mixing of steam at different temperatures.

[0095] In combination Figure 1 and Figure 2 As shown, in some embodiments, the first end of the flow guide channel 111 is connected to the steam generation assembly 190, and the second end of the flow guide channel 111 is connected to the cooking cavity 141. At least part of the flow guide channel 111 is inclined towards the cooking cavity 141 from the first end to the second end of the flow guide channel 111.

[0096] The at least part of the flow guide channel 111 is inclined towards the cooking cavity 141, so that the flow guide channel 111 guides the steam, allowing the steam to flow smoothly into the cooking cavity 141.

[0097] In combination Figure 1 and Figure 2 As shown, in some embodiments, the top of the innermost steam generation assembly 190 is connected to the shell 140.

[0098] The top of the innermost steam generation assembly 190 is connected to the bottom of the shell 140, so that the innermost steam generation assembly 190 is integrally arranged with the shell 140, reducing the number of components inside the cooking device 100 and facilitating the disassembly and assembly of the cooking device 100 by the user.

[0099] In some embodiments, the steam in the innermost steam generation assembly 190 is discharged from the top.

[0100] The steam generated by the innermost steam generation assembly 190 is discharged from the top, and the top of the innermost steam generation assembly 190 is connected to the bottom of the shell 140. Therefore, the innermost steam generation assembly 190 and the shell 140 can share part of the openings for steam flow, so that two sets of openings do not need to be provided for the innermost steam generation assembly 190 and the shell 140 respectively, which is conducive to reducing the processing difficulty of the product.

[0101] In combination Figure 1 , Figure 2 and Figure 1As shown in some embodiments, optionally, the shell 140 comprises a partition plate 145, which serves as the cavity bottom wall of the cooking cavities 141, and the steam holes 142 are arranged on the partition plate 145, and any two cooking cavities 141 are connected to the steam generation assembly 190 through different steam holes 142.

[0102] Any two cooking cavities 141 form independent steam transmission paths with the steam generation assembly 190, that is, each cooking cavity 141 can receive direct steam supply from the steam generation assembly 190 without passing through other cooking cavities 141.

[0103] Since each cooking cavity 141 is connected to the steam generation assembly 190 through an independent steam hole 142, the steam does not interfere with each other during transmission, thereby effectively avoiding the problem of cross-contamination between foods in different cooking cavities 141, and providing users with a more pure cooking experience.

[0104] Each cooking cavity 141 can directly receive steam from the steam generation assembly 190 without “transit” through other cooking cavities 141, which improves the utilization rate of steam and also ensures that the cooking cavities 141 far away from the steam generation assembly 190 can obtain sufficient amount of steam, thereby ensuring the uniformity and efficiency of cooking.

[0105] In one possible application, the shell 140 comprises: an outer shell 144, a plurality of partition plates 145, and an upper cover 146, the partition plates 145 are arranged in the outer shell 144, and the cooking cavities 141 are formed between adjacent two partition plates 145, and the uppermost cooking cavity 141 is located between the upper cover 146 and the uppermost partition plate 145.

[0106] As shown in combination Figure 2 , Figure 1 and Figure 2 , in some embodiments, optionally, at least two air inlet sub-zones 143 are arranged on the inner wall of the cooking cavity 141, a plurality of steam holes 142 are arranged in any air inlet sub-zone 143, the intervals between the at least two air inlet sub-zones 143 and the side of the shell 140 increase sequentially, and the steam generation assembly 190, the air inlet sub-zone 143, and the cooking cavity 141 correspond one by one.

[0107] A plurality of air inlet sub-zones 143 are arranged on the inner wall of the cooking cavity 141 for guiding steam into the cooking cavity 141. A plurality of steam holes 142 are arranged in any air inlet sub-zone 143, and the plurality of steam holes 142 in one air inlet sub-zone 143 are arranged along the circumferential direction of the cooking device 100. Figure 3As indicated by the arrow at point C, the spacing between multiple air intake zones 143 and the side of the housing 140 increases sequentially. To avoid steam cross-contamination between different cooking chambers 141, the spacing between the air intake zones 143 and the side of the housing 140 increases sequentially. This spacing design ensures that the lower cooking chamber 141 has space to form channels, and these channel spaces are physically isolated from each other.

[0108] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the housing 140 may optionally include a baffle 147, at least a portion of the cooking cavity 141 is provided with the baffle 147, and the steam generated by two adjacent steam generating assemblies 190 is separated in the cooking cavity 141 by the baffle 147.

[0109] A baffle plate 147 is installed inside the cooking cavity 141 to separate the steam flowing to different cooking cavities 141 and prevent the steam from mixing flavors.

[0110] Combination Figure 2 , Figure 1 and Figure 2 As shown, in some embodiments, optionally, the direction from the bottom of the steam generating assembly 190 to the top of the steam generating assembly 190 is the first direction ( Figure 3 (The arrow at H points to) at least two steam generating assemblies 190 have their exhaust positions arranged sequentially along the first direction; among the multiple intake zones 143, the direction from the innermost intake zone 143 to the outermost intake zone 143 is the second direction ( Figure 1 and Figure 2 Figure 3 Figure 1 Figure 1 Figure 3 (The arrow at point B points to)

[0111] In the second direction, at least two steam holes 142 in the air intake sections 143 are sequentially connected to at least two steam generating components 190 in the first direction.

[0112] The first direction refers to the direction from bottom to top, and the second direction refers to the direction from inside to outside. The steam generating assembly 190 is provided with a steam outlet 121. In at least two steam generating assemblies 190, the steam outlets 121 are distributed sequentially along the first direction. The uppermost steam outlet 121 is connected to the innermost air intake section 143, the second upper steam outlet 121 is connected to the second innermost air intake section 143, and so on. The lowermost steam outlet 121 is connected to the outermost air intake section 143. In this way, multiple steam outlets 121 can be neatly connected to multiple air intake sections 143, avoiding the problem of intersecting connection channels between multiple steam outlets 121 and multiple air intake sections 143, thus facilitating the processing of the connection channels between the steam outlets 121 and the air intake sections 143.
