Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and more specifically, to a base assembly and a cooking device. Background Technology

[0002] When cooking equipment has multiple sealing points, the areas that need to be sealed are usually sealed with soft rubber. This sealing method not only increases costs but also increases assembly difficulty. Utility Model Content

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

[0004] In view of this, in a first aspect, the present invention proposes a base assembly for a cooking device, the cooking device including a cooking cavity, the base assembly including: a base; a water tank located inside the base; a steam generating assembly located inside the water tank, the steam generating assembly having a steam outlet and a heating cavity, the heating cavity being connected to the water tank, the steam outlet being connected to the cooking cavity, and a first groove being provided on the top of the steam generating assembly along its circumference; and a drip tray located on top of the water tank and the steam generating assembly, the drip tray including a first supporting rib along its circumference, the first supporting rib extending into the first groove.

[0005] A steam generating component is installed in the water tank, occupying a portion of the tank's space. A heating element heats the water inside the steam generating component. Because the space inside the steam generating component is relatively small compared to the water tank, the water inside is heated to produce steam quickly, increasing the steam generation rate. During cooking, the cooking chamber can be filled with steam in a short time, which helps to speed up the cooking process. The steam generating component has a steam vent, through which the steam generated can be released into the cooking chamber, thus heating the food inside.

[0006] The drip tray is placed on the steam generating unit and / or water tank, with the cooking chamber located above it. During cooking, the drip tray collects and holds the juices flowing from the food, allowing for convenient and centralized processing of the juices and improving the ease of use of the cooking equipment. By covering the top of the water tank with the drip tray, no additional components are needed to work with the water tank, simplifying the structure of the cooking equipment.

[0007] To ensure that the steam generated within the steam generator enters the cooking chamber, the area between the drip tray and the steam generator needs to be sealed to prevent steam from flowing directly into the space between the steam generator and the water tank without entering the cooking chamber. In this design, a first groove is provided on the top of the steam generator, and this first groove is distributed circumferentially along the steam generator; that is, the first groove is a ring structure. A first support rib is provided at the bottom of the drip tray, extending into the first groove. The first support rib is also distributed circumferentially along the drip tray, and therefore is also a ring structure.

[0008] During cooking, steam condenses upon contact with the drip tray, and some of this condensation drips into the first groove. When the condensation in the first groove exceeds the bottom of the first support rib, a water seal is formed between the drip tray and the steam generator. This water seal prevents the steam from flowing directly between the steam generator and the water tank, ensuring that steam can smoothly enter the cooking cavity and improve the heating efficiency of the food. The first support rib and the first groove work together between the drip tray and the steam generator, achieving a seal between them through a water seal. Compared to a soft rubber seal, this design saves one sealing component, simplifying the base assembly structure and reducing both cost and assembly difficulty.

[0009] In addition, the base assembly according to the above-described technical solution provided by this utility model may also have the following additional technical features:

[0010] In some technical solutions, optionally, the steam generating assembly includes: a first top wall; a first surrounding rib disposed on the first top wall, the first surrounding rib being located inside the first supporting rib; a second surrounding rib disposed on the first top wall, the second surrounding rib being located outside the first supporting rib, a first groove being formed between the first top wall, the first surrounding rib and the second surrounding rib, and both the first surrounding rib and the second surrounding rib being spaced apart from the first supporting rib.

[0011] A first rib and a second rib are provided on the first top wall of the steam generating assembly. The first rib and the second rib protrude from the first top and the space enclosed between the first rib, the second rib and the first top wall serves as a first groove.

[0012] The first support rib is spaced apart from the first and second surrounding ribs on both sides. Condensate can drip into the area between the first support rib and the first surrounding rib, or into the area between the first support rib and the second surrounding rib, so that water seals can be formed on both sides of the first support rib, which helps to improve the sealing effect between the drip tray and the steam generating component.

[0013] In some technical solutions, optionally, with the first top wall as a reference, the second surrounding reinforcement is higher than the first surrounding reinforcement.

[0014] The higher height of the second retaining rib allows the first retaining rib to effectively limit the movement of the first supporting rib, preventing the drip tray from wobbling relative to the steam. The lower height of the first retaining rib ensures that when the liquid level in the first groove exceeds the top of the first retaining rib, condensate will overflow. This design prevents excessive condensate buildup in the first groove, allowing the small amount of condensate to evaporate quickly after cooking, thus preventing bacterial growth due to prolonged condensate accumulation.

[0015] In some technical solutions, the second rib may optionally abut against the bottom surface of the juice receiving tray.

[0016] The second rib is relatively high, allowing the juice tray to be placed on it, thus supporting the juice tray. The second rib not only serves as the enclosure structure for the first groove but also supports the juice tray, enabling it to perform multiple functions. This eliminates the need for an additional support structure for the juice tray and reduces the processing difficulty of the base assembly.

[0017] In some technical solutions, optionally, the first support rib abuts against the first top wall.

[0018] The bottom of the first support rib is attached to the first top wall, so that the first top wall can support the first support rib. The first top wall can not only serve as the enclosure structure of the first groove, but also support the juice tray, so that the first top wall can achieve multiple functions. Therefore, there is no need to set an additional support structure for the juice tray, reducing the processing difficulty of the base assembly.

[0019] In one possible application, the first top wall supports the first supporting rib, or the second surrounding rib supports the juice tray.

[0020] In one possible application, the first top wall supports the first supporting rib, while the second surrounding rib supports the juice tray.

[0021] In some technical solutions, the drip tray may optionally include: a stepped portion connected to the first supporting rib, a receiving groove formed between the stepped portion and the first supporting rib, and at least a portion of the second surrounding rib extending into the receiving groove.

[0022] The drip tray has a stepped structure, specifically a stepped portion, at least a portion of which is located above the second supporting rib. The stepped portion connects to the first supporting rib, and the stepped portion and the first supporting rib together form a receiving groove. When the drip tray is placed above the steam generating assembly, a portion of the second supporting rib extends into the receiving groove. The second supporting rib and the receiving groove cooperate with each other, further increasing the difficulty of steam flowing from the steam generating assembly into the water tank, thereby improving the sealing effect between the drip tray and the steam generating assembly.

[0023] In some technical solutions, the stepped portion may optionally include: a first connecting portion; a second connecting portion, one end of the second connecting portion being connected to the first connecting portion, the second connecting portion being located on the side of the first connecting portion away from the steam generating component, an included angle between the second connecting portion and the first connecting portion, a second end of the second connecting portion being connected to the first supporting rib, and the distance between the first connecting portion and the second surrounding rib being greater than the distance between the first supporting rib and the second surrounding rib.

[0024] The second connecting part is located on the side of the first connecting part away from the steam generating component. The two ends of the second connecting part are respectively connected to the first connecting part and the first supporting rib. The first connecting part and the first supporting rib serve as the sidewalls of the receiving tank, and the second connecting part serves as the bottom wall of the receiving tank.

[0025] The distance between the first connecting part and the second surrounding rib is relatively large, while the distance between the first supporting rib and the second surrounding rib is relatively small. That is, the second surrounding rib is closer to the first supporting rib, and the length of the first top wall is relatively short. In the case of processing errors, the smaller the distance between the second surrounding rib and the first supporting rib, the easier it is to ensure the contact effect between the second surrounding rib and the second connecting part, thereby improving the sealing effect between the steam generating component and the drip tray.

[0026] In some technical solutions, the drip tray may optionally include: a third connecting part, the first end of the first support rib is adjacent to the steam generating assembly, the second end of the first support rib is connected to the third connecting part, the third connecting part is the top of the steam generating assembly, and the distance between the first end of the first support rib and the second connecting part is smaller than the distance between the second end of the first support rib and the second connecting part.

[0027] The second connecting part is connected between the upper and lower ends of the first support rib, and the distance between the upper end of the first support rib and the second connecting part is greater than the distance between the lower end of the first support rib and the second connecting part. Therefore, the length of the first support rib extending out of the second connecting part is relatively large. The first support rib can guide the steam, promote the steam to flow to the steam port, reduce the pressure at the sealing part between the drip tray and the steam generating component, and further improve the sealing performance.

[0028] In some technical solutions, the steam generating assembly may optionally include: an inner cylinder connected to a first top wall, a first rib located between a second rib and the inner cylinder, a steam outlet located on the inner cylinder, and the first rib and the inner cylinder being spaced apart.

[0029] There is a certain distance between the first rib and the inner cylinder. As the steam in the inner cylinder flows upward, the first rib is less likely to obstruct the flow of steam, thereby reducing the impact on the steam flow.

[0030] In some technical solutions, optionally, the distance between the first rib and the inner cylinder is smaller than the distance between the first rib and the second rib.

[0031] The smaller distance between the first rib and the inner cylinder makes the first rib closer to the inner cylinder, which in turn makes the first groove closer to the inner cylinder. Steam is more easily blocked by the water seal formed in the first groove, thereby improving the sealing effect.

[0032] In some technical solutions, optionally, the drip tray is provided with a steam recovery port and an exhaust port. The steam in the cooking chamber flows back into the water tank through the steam recovery port, and the returned steam is discharged through the exhaust port.

[0033] As the amount of steam in the cooking chamber gradually increases, the steam can flow back into the water tank through the steam recovery port. The returned steam flows in the water tank for a period of time before being discharged through the vent. This causes some of the steam to condense in the water tank, which also cools the steam. This reduces the amount of steam emitted and lowers the steam temperature, preventing scalding of users.

[0034] In some technical solutions, the steam recovery port and the exhaust port are optionally located on opposite sides of the steam generating assembly.

[0035] The steam recovery port and the exhaust port are located on opposite sides of the steam generating assembly, which allows the exhaust port to be moved away from the steam recovery port, enabling the returned steam to flow in the water tank for a longer period of time, thereby improving the heat exchange and condensation effect of the steam.

[0036] In some technical solutions, optionally, a steam flow channel is provided inside the water tank, and the steam recovery port and the exhaust port are connected through the steam flow channel.

[0037] The water tank is equipped with a steam flow channel. The steam in the cooking process flows back into the steam flow channel through the steam recovery port. The steam in the steam flow channel is discharged through the exhaust port. The steam flow channel guides the steam, preventing the returned steam from flowing to other places and ensuring that the steam after heat exchange can be stably discharged to the outside through the exhaust port.

[0038] In some technical solutions, optionally, a steam flow channel is formed by enclosing the drip tray, the steam generating component, and the water tank.

[0039] The steam generating unit and water tank serve as the side of the steam flow channel, while the drip tray serves as the top of the steam flow channel. This creates a steam flow channel between the drip tray, the steam generating unit, and the water tank, eliminating the need for additional auxiliary structures and simplifying the structure of the cooking equipment.

[0040] In some technical solutions, the steam flowing back into the steam channel may optionally exchange heat with the water in the water tank.

[0041] Because the water tank contains water, the steam flowing into it can exchange heat directly or indirectly with the water, thus lowering the steam's temperature. The heat from the high-temperature steam is transferred to the water, achieving heat recovery and preventing waste. Furthermore, heating the water with high-temperature steam increases its temperature, allowing the water in the steam generator to be quickly heated into steam, reducing the heating time and energy consumption of the steam generator, thereby improving energy efficiency. The heat exchange between the steam and water also lowers the steam's temperature, preventing scalding from the exhaust steam. The steam returning to the water tank is discharged through the vent.

[0042] In some technical solutions, the first groove and steam channel are optionally located below the drip tray.

[0043] The first groove is located in the space below the drip tray, so the sealing structure between the drip tray and the steam generating component is located inside the water tank, ensuring that the steam flowing into the cooking process does not pass through the space between the steam generating component and the water tank first.

[0044] The steam channel is located in the space below the juice receiving tray, that is, the steam channel is located inside the water tank. The temperature inside the water tank is relatively low, which reduces the overflow of high-temperature steam and improves the condensation effect of the steam.

[0045] In some technical solutions, optionally, a second groove is provided on the top of the water tank along the circumference of the water tank, and a second support rib is provided on the juice receiving tray, the second support rib extending into the second groove.

[0046] A vent is provided on the base, through which steam flowing back into the water tank is discharged. To prevent steam from escaping to the outside through the gap between the drip tray and the water tank, the area between the drip tray and the water tank needs to be sealed. In this design, a second groove is provided on the top of the water tank, and the second groove is distributed circumferentially around the water tank; that is, the second groove is a ring structure. A second support rib is provided on the bottom of the drip tray, extending into the second groove. The second support rib is also distributed circumferentially around the drip tray, and therefore is also a ring structure.

[0047] During cooking, steam condenses upon contact with the drip tray, and some of this condensation drips into the second groove. When the condensation in the second groove exceeds the bottom of the second support rib, a water seal is formed between the drip tray and the water tank. This water seal prevents steam from flowing back into the water tank and escapes through the space between the drip tray and the water tank. The second support rib and the second groove work together between the drip tray and the water tank, achieving a seal through a water seal. Compared to a soft rubber seal, this design saves one sealing component, thus simplifying the base assembly structure, reducing costs, and simplifying assembly.

[0048] In some technical solutions, optionally, the water tank includes: a second top wall; a third surrounding rib, disposed on the second top wall, the third surrounding rib being located inside the second supporting rib; a fourth surrounding rib, disposed on the second top wall, the third surrounding rib being located outside the second supporting rib, a second groove being formed between the second top wall, the third surrounding rib and the fourth surrounding rib, and the third surrounding rib and the fourth surrounding rib being spaced apart from the second supporting rib.

[0049] A first rib and a second rib are provided on the first top wall of the steam generating assembly. The first rib and the second rib protrude from the first top and the space enclosed between the first rib, the second rib and the first top wall serves as a first groove.

[0050] The second support rib is spaced apart from the third and fourth surrounding ribs on both sides. Condensate can drip into the area between the second and third supporting ribs, or into the area between the second and fourth supporting ribs, so that water seals can be formed on both sides of the second support rib, which helps to improve the sealing effect between the drip tray and the water tank.

[0051] In some technical solutions, optionally, with the second top wall as a reference, the fourth surrounding reinforcement is higher than the third surrounding reinforcement.

[0052] The fourth rib is relatively high, effectively limiting the movement of the second support rib and preventing the drip tray from wobbling relative to the water tank. The third rib is relatively low; when the liquid level in the second groove exceeds the top of the third rib, the condensate will overflow into the water tank. This design prevents excessive condensate buildup in the second groove. After cooking, the small amount of condensate in the second groove evaporates quickly, preventing bacterial growth due to prolonged condensation.

[0053] In some technical solutions, the second support rib may optionally abut against the second top wall.

[0054] The bottom of the second support rib fits into the second top wall, allowing the second top wall to support the second support rib. The second top wall can not only serve as the enclosure structure for the second groove, but also support the juice tray, enabling the second top wall to perform multiple functions. This eliminates the need for an additional support structure for the juice tray and reduces the processing difficulty of the base assembly.

[0055] In some technical solutions, the base assembly may optionally include a fan, disposed on the base, for blowing airflow toward the exhaust port.

[0056] The airflow driven by the fan accelerates the steam's velocity. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is large, and the water molecules in the steam quickly mix with the air, making it difficult to form visible water droplets or condensation. At the same time, the high-speed flow of steam also reduces the possibility of water molecules accumulating in one place, thus avoiding the formation of condensation.

[0057] Secondly, this utility model proposes a cooking device, including: a housing, the housing having a cooking cavity inside; and a base assembly as described in the first aspect, the housing being disposed on the base assembly.

[0058] In some technical solutions, optionally, a steam return channel is provided inside the shell, one end of which extends toward the top of the shell, and the other end of which is connected to the water tank, so that the steam in the cooking cavity flows into the water tank through the steam return channel.

[0059] After steam flows into the cooking chamber, it rises and flows to the top, then into the steam return channel. With some steam reaching the top, the chamber is essentially filled, ensuring a consistently high temperature throughout and even heating of the food. The steam then returns to the water tank for condensation, eliminating the need for steam vents on the casing and preventing scalding.

Detailed Implementation

[0075] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0076] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0077] The following reference Figures 1 to 11 This invention describes a base assembly and cooking device provided according to some embodiments of the present invention.

[0078] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 As shown, in some embodiments of this utility model, a base assembly 100 is provided. The base assembly 100 is used for a cooking device, which includes a cooking cavity 210. The base assembly 100 includes: a base 110, a water tank 120, a steam generating assembly 130, and a drip tray 150. The water tank 120 is located inside the base 110, and the steam generating assembly 130 is located inside the water tank 120. The steam generating assembly 130 is provided with a steam outlet 131 and a heating cavity 132. The heating cavity 132 is connected to the water tank 120, and the steam outlet 131 is used to connect to the cooking cavity 210. Along the circumference of the steam generating assembly 130... Figure 8 (As indicated by the arrow at C1), a first groove 133 is provided on the top of the steam generating assembly 130. A drip tray 150 is located on top of the water tank 120 and the steam generating assembly 130, extending circumferentially (with...) along the... Figure 8 (The arrow at C1 points in the same direction), the juice receiving tray 150 is provided with a first support rib 152, and the first support rib 152 extends into the first groove 133.

[0079] A steam generating assembly 130 is installed in the water tank 120, occupying a portion of the space within the water tank 120. A heating element 140 is used to heat the water inside the steam generating assembly 130, and is located below the steam generating assembly 130. Because the space inside the steam generating assembly 130 is relatively small compared to the water tank 120, the water inside the steam generating assembly 130 generates steam more quickly when heated, which can increase the steam generation rate. When using the cooking equipment, the cooking chamber 210 can be filled with steam in a short time, which is beneficial for improving the cooking speed of food. The steam generating assembly 130 is provided with a steam outlet 131, through which the steam generated inside the steam generating assembly 130 can be discharged into the cooking chamber 210, thereby heating the food inside the cooking chamber 210.

[0080] The drip tray 150 is placed on the steam generating assembly 130 and / or the water tank 120, and the cooking chamber 210 is located above the drip tray 150. During cooking, the drip tray 150 is used to collect and collect the juices flowing from the food, making it convenient for users to centrally process the juices and improving the ease of use of the cooking equipment. By covering the top of the water tank 120 with the drip tray 150, no additional components that cooperate with the water tank 120 are required, which simplifies the structure of the cooking equipment.

[0081] To ensure that the steam generated in the steam generating assembly 130 enters the cooking chamber 210, the area between the drip tray 150 and the steam generating assembly 130 needs to be sealed to prevent some steam from flowing directly into the space between the steam generating assembly 130 and the water tank 120 without entering the cooking chamber 210. In this design, a first groove 133 is provided on the top of the steam generating assembly 130, and the first groove 133 is distributed circumferentially along the steam generating assembly 130, that is, the first groove 133 is a ring structure. A first support rib 152 is provided on the bottom of the drip tray 150, and the first support rib 152 extends into the first groove 133. The first support rib 152 is distributed circumferentially along the drip tray 150, therefore the first support rib 152 is also a ring structure.

[0082] During cooking, steam encounters the drip tray 150 and condenses. Some of this condensate drips into the first groove 133. When the condensate in the first groove 133 is higher than the bottom of the first support rib 152, a water seal is formed between the drip tray 150 and the steam generating assembly 130. This water seal prevents the steam from flowing directly between the steam generating assembly 130 and the water tank 120, ensuring that the steam can smoothly enter the cooking cavity 210 and improve the heating efficiency of the steam on the food. The first support rib 152 and the first groove 133 work together between the drip tray 150 and the steam generating assembly 130, achieving a seal between them through a water seal. Compared to a soft rubber seal, this solution saves one sealing component, thus simplifying the structure of the base assembly 100. This not only reduces costs but also simplifies the assembly process.

[0083] The heating element 140 is fixed to the water tank 120, and the steam generating assembly 130 and the heating element 140 are located above the center of the water tank 120. The top of the steam generating assembly 130 is connected to the drip tray 150.

[0084] In this embodiment, a water seal is used to achieve a good seal between the drip tray 150 and the steam generating assembly 130. Even if the gap between the bottom of the first support rib 152 and the top of the steam generating assembly 130 is uneven, a good seal can still be achieved.

[0085] Combination Figure 3 , Figure 4 and Figure 8As shown, in some embodiments, optionally, the steam generating assembly 130 includes: a first top wall 134, a first surrounding rib 135, and a second surrounding rib 136. The first surrounding rib 135 and the second surrounding rib 136 are disposed on the first top wall 134, the first surrounding rib 135 is located inside the first supporting rib 152, and the second surrounding rib 136 is located outside the first supporting rib 152. A first groove 133 is formed between the first top wall 134, the first surrounding rib 135, and the second surrounding rib 136. Both the first surrounding rib 135 and the second surrounding rib 136 are spaced apart from the first supporting rib 152.

[0086] A first rib 135 and a second rib 136 are provided on the first top wall 134 of the steam generating assembly 130. The first rib 135 and the second rib 136 protrude from the first top and the space enclosed between the first rib 135, the second rib 136 and the first top wall 134 is a first groove 133.

[0087] The first support rib 152 is spaced apart from the first surrounding rib 135 and the second surrounding rib 136 on both sides. Condensate can drip into the area between the first support rib 152 and the first surrounding rib 135, or into the area between the first support rib 152 and the second surrounding rib 136, so that water seals can be formed on both sides of the first support rib 152, which is beneficial to improving the sealing effect between the drip tray 150 and the steam generating assembly 130.

[0088] like Figure 4 As shown, in some embodiments, optionally, with the first top wall 134 as a reference, the second surrounding reinforcement 136 is higher than the first surrounding reinforcement 135.

[0089] The second retaining rib 136 is relatively high, allowing the first retaining rib 135 to effectively limit the first supporting rib 152, preventing the drip tray 150 from wobbling relative to the steam generating assembly 130. The first retaining rib 135 is relatively low, so when the liquid level in the first groove 133 exceeds the top of the first retaining rib 135, the condensate will overflow from the first groove 133. This design prevents excessive condensate buildup in the first groove 133, and the small amount of condensate in the first groove 133 can evaporate quickly after cooking, thus preventing bacterial growth due to prolonged condensate accumulation.

[0090] Combination Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, the second reinforcing rib 136 may optionally abut against the bottom surface of the drip tray 150.

[0091] The second rib 136 is relatively high, allowing the juice tray 150 to be placed on it, thus supporting the juice tray 150. The second rib 136 can not only serve as the enclosure structure of the first groove 133, but also support the juice tray 150, enabling it to perform multiple functions. This eliminates the need for an additional support structure for the juice tray 150, reducing the processing difficulty of the base assembly 100.

[0092] Combination Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, optionally, the first support rib 152 abuts against the first top wall 134.

[0093] The bottom of the first support rib 152 is attached to the first top wall 134, so that the first top wall 134 can support the first support rib 152. The first top wall 134 can not only serve as the enclosure structure of the first groove 133, but also support the juice tray 150, so that the first top wall 134 can achieve multiple functions, thereby eliminating the need to set up an additional support structure for the juice tray 150 and reducing the processing difficulty of the base assembly 100.

[0094] In one possible application, the first top wall 134 supports the first support rib 152, or the second surrounding rib 136 supports the juice tray 150.

[0095] In one possible application, the first top wall 134 supports the first support rib 152, while the second surrounding rib 136 supports the juice tray 150.

[0096] like Figure 4 As shown, in some embodiments, optionally, the juice receiving tray 150 further includes: a stepped portion 154, the stepped portion 154 being connected to the first support rib 152, a receiving groove 155 being formed between the stepped portion 154 and the first support rib 152, and at least a portion of the second surrounding rib 136 extending into the receiving groove 155.

[0097] A stepped structure, namely a stepped portion 154, is provided on the drip tray 150. At least a portion of the stepped portion 154 is located above the second supporting rib 136. The stepped portion 154 is connected to the first supporting rib 152, and the stepped portion 154 and the first supporting rib 152 enclose a receiving groove 155. When the drip tray 150 is placed above the steam generating assembly 130, a portion of the second supporting rib 136 extends into the receiving groove 155. The second supporting rib 136 and the receiving groove 155 cooperate with each other, which can further increase the difficulty of steam flowing from the steam generating assembly 130 into the water tank 120, thereby improving the sealing effect between the drip tray 150 and the steam generating assembly 130.

[0098] like Figure 4 As shown, in some embodiments, optionally, the step portion 154 includes: a first connecting portion 156 and a second connecting portion 157, one end of the second connecting portion 157 being connected to the first connecting portion 156, the second connecting portion 157 being located on the side of the first connecting portion 156 away from the steam generating assembly 130, an included angle between the second connecting portion 157 and the first connecting portion 156, the second end of the second connecting portion 157 being connected to the first supporting rib 152, and the distance between the first connecting portion 156 and the second surrounding rib 136 being greater than the distance between the first supporting rib 152 and the second surrounding rib 136.

[0099] The second connecting part 157 is disposed on the side of the first connecting part 156 away from the steam generating assembly 130. The two ends of the second connecting part 157 are respectively connected to the first connecting part 156 and the first supporting rib 152. The first connecting part 156 and the first supporting rib 152 serve as the sidewalls of the receiving groove 155, and the second connecting part 157 serves as the bottom wall of the receiving groove 155.

[0100] The distance between the first connecting part 156 and the second surrounding rib 136 is relatively large, while the distance between the first supporting rib 152 and the second surrounding rib 136 is relatively small. That is, the second surrounding rib 136 is closer to the first supporting rib 152, and the length of the first top wall 134 is relatively short. In the case of processing errors, the smaller the distance between the second surrounding rib 136 and the first supporting rib 152, the easier it is to ensure the contact effect between the second surrounding rib 136 and the second connecting part 157, thereby improving the sealing effect between the steam generating assembly 130 and the drip tray 150.

[0101] like Figure 4 As shown, in some embodiments, optionally, the drip tray 150 further includes: a third connecting portion 158, the first end of the first support rib 152 is adjacent to the steam generating assembly 130, the second end of the first support rib 152 is connected to the third connecting portion 158, the third connecting portion 158 is the top of the steam generating assembly 130, and the distance between the first end of the first support rib 152 and the second connecting portion 157 is smaller than the distance between the second end of the first support rib 152 and the second connecting portion 157.

[0102] The second connecting part 157 is connected between the upper and lower ends of the first support rib 152, and the distance between the upper end of the first support rib 152 and the second connecting part 157 is greater than the distance between the lower end of the first support rib 152 and the second connecting part 157. Therefore, the length of the first support rib 152 extending out of the second connecting part 157 is relatively large. The first support rib 152 can guide the steam, promote the steam to flow to the steam port 131, reduce the pressure at the sealing part between the drip tray 150 and the steam generating assembly 130, and further improve the sealing performance.

[0103] like Figure 4As shown, in some embodiments, optionally, the steam generating assembly 130 further includes: an inner cylinder 137 connected to a first top wall 134, a first surrounding rib 135 located between a second surrounding rib 136 and the inner cylinder 137, and a steam port 131 disposed on the inner cylinder 137, with the first surrounding rib 135 and the inner cylinder 137 spaced apart.

[0104] There is a certain distance between the first rib 135 and the inner cylinder 137. During the upward flow of steam in the inner cylinder 137, the first rib 135 is less likely to obstruct the flow of steam, thereby reducing the impact on the steam flow.

[0105] like Figure 8 As shown, in one possible application, the steam generating assembly 130 further includes an outer cylinder 138, an inner cylinder 137 connected to the outer cylinder 138, the inner cylinder 137 located inside the outer cylinder 138, a steam port 131 disposed on the inner cylinder 137, and the space inside the inner cylinder 137 serving as a heating chamber 132. The inner cavity of the outer cylinder 138 is connected to the water tank 120. Exemplarily, an opening can be made in the outer cylinder 138, or a notch can be provided at the bottom of the outer cylinder 138, so that water inside the water tank 120 can be replenished into the outer cylinder 138, and an opening can be made at the bottom of the inner cylinder 137, so that water inside the outer cylinder 138 can be replenished into the inner cylinder 137. The space inside the inner cylinder 137 is small, and the small amount of water inside the inner cylinder 137 can be quickly heated into steam, increasing the steam generation rate.

[0106] The steam generating assembly 130 also includes a heating element 140 for heating the water in the outer cylinder 138.

[0107] like Figure 4 As shown, in some embodiments, optionally, the distance between the first rib 135 and the inner cylinder 137 is smaller than the distance between the first rib 135 and the second rib 136.

[0108] The smaller distance between the first rib 135 and the inner cylinder 137 makes the first rib 135 closer to the inner cylinder 137, which in turn makes the first groove 133 closer to the inner cylinder 137. Steam is more easily blocked by the water seal formed in the first groove 133, thereby improving the sealing effect.

[0109] Combination Figure 3 and Figure 6 As shown, in some embodiments, optionally, the drip tray 150 is provided with a steam recovery port 159 and an exhaust port 151. The steam in the cooking chamber flows back to the water tank 120 through the steam recovery port 159, and the returned steam is discharged through the exhaust port 151.

[0110] As the amount of steam in the cooking cavity gradually increases, the steam in the cooking cavity can flow back to the water tank 120 through the steam recovery port 159. The returned steam flows in the water tank 120 for a period of time and then is discharged through the exhaust port 151, which causes some of the steam to condense in the water tank 120, thus cooling the steam. This reduces the amount of steam discharged and lowers the steam temperature, preventing scalding of users.

[0111] Figure 3 Arrows inside the cooking equipment are used to indicate the direction of steam flow. Figure 7 The middle arrow indicates the direction of the steam flowing back into the water tank 120.

[0112] Combination Figure 3 and Figure 6 As shown, in some embodiments, optionally, the steam recovery port 159 and the exhaust port 151 are located on opposite sides of the steam generating assembly 130.

[0113] The steam recovery port 159 and the exhaust port 151 are located on opposite sides of the steam generating assembly 130, so that the exhaust port 151 can be moved away from the steam recovery port 159, allowing the returned steam to flow in the water tank 120 for a longer time, thereby improving the heat exchange and condensation effect of the steam.

[0114] Combination Figure 3 and Figure 6 As shown, in some embodiments, optionally, the water tank 120 is provided with a steam flow channel 125, and the steam recovery port 159 and the exhaust port 151 are connected through the steam flow channel 125.

[0115] The water tank 120 is equipped with a steam flow channel 125. The steam in the cooking process flows back into the steam flow channel 125 through the steam recovery port 159. The steam in the steam flow channel 125 is discharged through the exhaust port 151. The steam flow channel 125 guides the steam, preventing the returned steam from flowing to other places and ensuring that the steam after heat exchange can be stably discharged to the outside through the exhaust port 151.

[0116] Combination Figure 3 and Figure 6 As shown, in some embodiments, optionally, a steam flow channel 125 is formed between the drip tray 150, the steam generating assembly 130, and the water tank 120.

[0117] The steam generating assembly 130 and the water tank 120 serve as the sides of the steam flow channel 125, and the drip tray 150 serves as the top of the steam flow channel 125, thereby forming the steam flow channel 125 between the drip tray 150, the steam generating assembly 130 and the water tank 120. No additional auxiliary structures are required to form the steam flow channel 125, which helps to simplify the structure of the cooking equipment.

[0118] In some embodiments, the steam flowing back into the steam channel 125 may optionally exchange heat with the water in the water tank 120.

[0119] Since the water tank 120 contains water, the steam flowing into it can exchange heat directly or indirectly with the water, thereby reducing the steam temperature. The heat from the high-temperature steam is transferred to the water, thus recovering the steam's heat and preventing waste. Furthermore, heating the water with high-temperature steam increases its temperature, allowing the water in the steam generating assembly 130 to be quickly heated into steam, reducing the heating time and energy consumption of the steam generating assembly 130, thus improving energy efficiency. The heat exchange between the steam and water also lowers the steam temperature, preventing scalding of users. The steam returning to the water tank 120 is discharged through the vent 151.

[0120] like Figure 3 As shown, in some embodiments, optionally, the first groove 133 and the steam channel 125 are located below the drip tray 150.

[0121] The first groove 133 is located in the space below the drip tray 150. Therefore, the sealing structure between the drip tray 150 and the steam generating assembly 130 is located in the water tank 120, ensuring that the steam flowing into the cooking process does not pass through the space between the steam generating assembly 130 and the water tank 120 first.

[0122] The steam flow channel 125 is located in the space below the drip tray 150, that is, the steam flow channel 125 is located inside the water tank 120. The temperature inside the water tank 120 is relatively low, reducing the overflow of high-temperature steam and improving the condensation effect of the steam. Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, along the circumference of the water tank 120 ( Figure 6 (The arrow at C2 points to) The top of the water tank 120 is provided with a second groove 121, and the juice receiving tray 150 is provided with a second support rib 153, which extends into the second groove 121.

[0123] A vent 151 is provided on the base 110, through which steam flowing back into the water tank 120 is discharged. To prevent steam from escaping to the outside through the gap between the drip tray 150 and the water tank 120, the area between them needs to be sealed. In this design, a second groove 121 is provided on the top of the water tank 120, and the second groove 121 is distributed circumferentially around the water tank 120, i.e., the second groove 121 is a ring structure. A second support rib 153 is provided on the bottom of the drip tray 150, extending into the second groove 121, and is also distributed circumferentially around the drip tray 150, therefore the second support rib 153 is also a ring structure.

[0124] During cooking, steam encounters the drip tray 150 and condenses. Some of this condensate drips into the second groove 121. When the condensate in the second groove 121 is higher than the bottom of the second support rib 153, a water seal is formed between the drip tray 150 and the water tank 120. This water seal prevents steam from flowing back into the water tank 120 and is thus prevented from escaping through the space between the drip tray 150 and the water tank 120. The second support rib 153 and the second groove 121, positioned between the drip tray 150 and the water tank 120, work together to achieve a water seal between them. Compared to a soft rubber seal, this design saves one sealing component, thus simplifying the structure of the base assembly 100. This not only reduces costs but also simplifies the assembly process.

[0125] Combination Figure 3 and Figure 5 As shown, in some embodiments, optionally, the water tank 120 includes: a second top wall 122, a third surrounding rib 123, and a fourth surrounding rib 124. The third surrounding rib 123 and the fourth surrounding rib 124 are disposed on the second top wall 122. The third surrounding rib 123 is located inside the second support rib 153, and the third surrounding rib 124 is located outside the second support rib 153. A second groove 121 is formed between the second top wall 122, the third surrounding rib 123, and the fourth surrounding rib 124. The third surrounding rib 123 and the fourth surrounding rib 124 are both spaced apart from the second support rib 153.

[0126] A first rib 135 and a second rib 136 are provided on the first top wall 134 of the steam generating assembly 130. The first rib 135 and the second rib 136 protrude from the first top and the space enclosed between the first rib 135, the second rib 136 and the first top wall 134 is a first groove 133.

[0127] The second support rib 153 is spaced apart from the third rib 123 and the fourth rib 124 on both sides. Condensate can drip into the area between the second support rib 153 and the third rib 123, or into the area between the second support rib 153 and the fourth rib 124, so that water seals can be formed on both sides of the second support rib 153, which helps to improve the sealing effect between the drip tray 150 and the water tank 120.

[0128] By forming a water seal in the first groove 133 and the second groove 121, there is no need for a structure that restricts the steam flow path in the water tank 120. This allows for a larger space in the water tank 120 for steam flow, resulting in better heat exchange and recovery of water vapor.

[0129] like Figure 5 As shown, in some embodiments, optionally, with the second top wall 122 as a reference, the fourth surrounding reinforcement 124 is higher than the third surrounding reinforcement 123.

[0130] The fourth retaining rib 124 is relatively high, allowing it to effectively limit the second supporting rib 153 and prevent the drip tray 150 from wobbling relative to the water tank 120. The third retaining rib 123 is relatively low; when the liquid level in the second groove 121 exceeds the top of the third retaining rib 123, the condensate will overflow from the second groove 121 and flow into the water tank 120. This design prevents excessive condensate buildup in the second groove 121. After cooking, the small amount of condensate in the second groove 121 evaporates quickly, thus preventing bacterial growth due to prolonged condensate accumulation.

[0131] like Figure 5 As shown, in some embodiments, optionally, the second support rib 153 abuts against the second top wall 122.

[0132] The bottom of the second support rib 153 is attached to the second top wall 122, so that the second top wall 122 can support the second support rib 153. The second top wall 122 can not only serve as the enclosure structure of the second groove 121, but also support the juice tray 150, so that the second top wall 122 can achieve multiple functions, thereby eliminating the need to set up an additional support structure for the juice tray 150 and reducing the processing difficulty of the base assembly 100.

[0133] Combination Figure 3 and Figure 10 As shown, in some embodiments, the base assembly 100 may optionally include a fan 160, which is disposed on the base 110 and is used to blow airflow toward the exhaust port 151.

[0134] The airflow driven by the fan accelerates the steam's velocity. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is large, and the water molecules in the steam quickly mix with the air, making it difficult to form visible water droplets or condensation. At the same time, the high-speed flow of steam also reduces the possibility of water molecules accumulating in one place, thus avoiding the formation of condensation.

[0135] Figure 10 The middle arrow is used to indicate the direction of steam flow.

[0136] In one possible embodiment, the base assembly 100 further includes a controller 170 located within the base 110.

[0137] In one possible embodiment, an exhaust port 151 is provided on the juice tray 150, an exhaust port 151 is provided above the fan 160, and a controller 170 is located below the fan 160.

[0138] Combination Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a cooking device is proposed, including: a housing 200 and a base assembly 100 as described in any of the above embodiments. The housing 200 has a cooking cavity 210 inside and is disposed on the base assembly 100. The cooking device in this embodiment can achieve the technical effects of the base assembly 100 in any of the above embodiments, and will not be described in detail here.

[0139] like Figure 3 As shown, the housing 200 includes an outer shell 220, a partition 240, and a cover 230. The outer shell 220 rests on the drip tray 150, the cover 230 covers the top wall of the outer shell 220, and the partition 240 is located inside the outer shell 220. There can be multiple partitions 240. For example, in this embodiment, there are two partitions 240: one placed above the drip tray 150 and the other on the upper half of the outer shell 220. The partitions 240 are used to support food or tableware. In other embodiments, the number of partitions 240 can be increased to increase the number of layers for placing food.

[0140] Combination Figure 3 , Figure 6 , Figure 7 and Figure 11 As shown, in some embodiments, optionally, a steam return channel 300 is provided inside the housing 200. One end of the steam return channel 300 extends toward the top of the housing 200, and the other end of the steam return channel 300 is connected to the water tank 120. The steam in the cooking cavity 210 flows into the water tank 120 through the steam return channel 300.

[0141] After steam flows into the cooking chamber 210, it rises within the chamber. Upon reaching the top of the chamber, it flows into the steam return channel 300. With some steam reaching the top, the chamber is essentially filled, ensuring a consistently high temperature throughout and guaranteeing even heating of the food. The steam then returns to the water tank 120 via the steam return channel 300 for condensation. Therefore, there is no need for steam vents on the casing 200, preventing scalding of the user.

[0142] In this embodiment, the steam return channel 300 is connected to the water tank 120 through the steam recovery port 159.

[0143] For example, the steam return channel 300 is a tubular structure installed inside the housing 200, or the steam return channel 300 is integrally disposed inside the housing 200.

[0144] Figure 11 The middle arrow indicates the direction of steam flow back to water tank 120.
