Description

TECHNICAL FIELD

[0001] The utility model relates to cooking equipment technical field, specifically, a base assembly and cooking equipment. BACKGROUND

[0002] The cooking equipment can produce a large amount of steam in the cooking process, when the high-temperature steam is discharged to the indoor space, the condensate water produced by the steam can be attached to the cabinet, which increases the workload of the user for cleaning around the cooking equipment. SUMMARY

[0003] The utility model aims at solving one of the technical problems existing in prior art or related art.

[0004] Therefore, in a first aspect, the utility model provides a base assembly, the base assembly is used for cooking equipment, the cooking equipment includes a cooking cavity, the base assembly is provided with an exhaust port, and the base assembly comprises: a base; a water tank located in the base; a heating piece arranged on the water tank, the heating piece is used for heating the water in the water tank to provide steam into the cooking cavity; and a fan assembly arranged in the base, external gas is sucked into the fan assembly through the air inlet side of the fan assembly, the air outlet side of the fan assembly is communicated with the exhaust port, and the airflow blown by the fan assembly and the steam flowing back to the water tank from the cooking cavity are discharged through the exhaust port.

[0005] The heating piece is used for heating the water in the water tank to generate steam, and the steam can be discharged into the cooking cavity, so that the food in the cooking cavity can be heated.

[0006] As the amount of steam in the cooking cavity gradually increases, the steam in the cooking cavity can flow back to the water tank, and since the water tank contains water, the steam flowing into the water tank can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The heat of the high-temperature steam is transferred to the water, thereby realizing the recovery of the steam heat and avoiding the waste of the steam heat. After the steam exchanges heat with the water, the temperature of the steam can be reduced, thereby avoiding scalding the user by the discharged steam.

[0007] When the fan assembly operates, the fan assembly drives the airflow to be discharged through the air outlet side, the air outlet side is communicated with the exhaust port, so that the airflow discharged from the air outlet side flows to the exhaust port, the steam flowing back to the water tank is also discharged outward through the exhaust port, and the airflow and the steam can be mixed and discharged at the exhaust port.

[0008] Since the temperature of the airflow driven by the fan assembly is lower than the temperature of the steam, the airflow discharged from the exhaust port can condense the steam and quickly disperse the steam, the mixed gas quickly flows and diffuses, the contact area between the steam and the surrounding air is large, the water molecules in the steam quickly mix with the air, and it is difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules gathering in a certain place, thereby avoiding the formation of condensed water. When the cooking device is running, it is not easy to form condensed water on the cabinet, reducing the workload of the user for cleaning around the cooking device.

[0009] The steam and the airflow are mixed at the exhaust port, and the high-temperature steam does not flow through the fan assembly, avoiding damage to the inside of the fan assembly due to high temperature, ensuring the running stability of the fan assembly, and reducing the damage rate of the fan assembly.

[0010] In addition, the base assembly in the above technical scheme according to the utility model can also have the following additional technical features:

[0011] In some technical solutions, the air outlet side of the fan assembly and the inside of the water tank are independent of each other.

[0012] In this scheme, the air outlet side and the inside of the water tank are independently arranged, and during the outward flow of the steam in the water tank, the steam does not pass through the air outlet side of the fan assembly, further reducing the influence of high-temperature steam on the fan assembly.

[0013] When the fan assembly is running, the blown airflow can avoid the steam flowing into the fan assembly, and since the air outlet side and the inside of the water tank are independently arranged, even if the fan assembly is in a stopped running state, the steam in the water tank is not easy to enter the fan assembly, reducing the damage rate of the fan assembly.

[0014] In some technical solutions, a separation air duct is arranged between the air outlet side of the fan assembly and the water tank, the airflow blown by the fan assembly flows to the exhaust port through the separation air duct, and the separation air duct is used to separate the airflow blown by the fan assembly from the steam.

[0015] The separation air duct is arranged between the air outlet side and the water tank, the air outlet side is in communication with the separation air duct, and the airflow blown by the fan assembly flows to the exhaust port through the separation air duct. The steam in the water tank flows to the exhaust port outside the separation air duct, avoiding the steam flowing through the air outlet side, and reducing the damage rate of the fan assembly.

[0016] In some technical solutions, one end of the separation air duct extends to the exhaust port, or one end of the separation air duct is arranged in a spaced manner with the exhaust port, and the airflow discharged from the separation air duct mixes with the steam and then flows to the exhaust port.

[0017] The isolation air duct can extend to the exhaust port, so that the air flow discharged by the fan assembly directly flows to the exhaust port through the isolation air duct, and the air flow cannot flow into the interior of the base assembly, and the air flow and the steam can only be mixed at the exhaust port, the air flow cools the steam at the exhaust port, and the steam is dispersed.

[0018] Alternatively, the isolation air duct does not directly extend to the exhaust port, that is, a gap is left between the isolation air duct and the exhaust port, and after the air flow discharged by the fan assembly flows out of the isolation air duct, the air flow and the steam are mixed in the base assembly and then flow to the exhaust port. The steam has been cooled in advance in the interior of the base assembly when flowing through the exhaust port, so that the user is not easily scalded by the steam even if the user's hand contacts the exhaust port, further improving the safety of the user when using the cooking device.

[0019] In some technical solutions, the base assembly further comprises an exhaust portion, at least a portion of the exhaust portion extends into the water tank, the exhaust portion is provided with a first air outlet, the first air outlet is in communication with the exhaust port, at least a portion of the isolation air duct is located in the exhaust portion, and the air outlet side of the fan assembly and the exhaust port are in communication through the isolation air duct in the exhaust portion.

[0020] The exhaust portion is provided on the water tank, the air flow blown by the fan assembly is discharged outward through the exhaust portion, and the exhaust portion serves as a structure for separating the air flow and the steam, so that the air flow flows to the exhaust port in the exhaust portion, the steam is prevented from flowing through the fan assembly, and the fan assembly is prevented from being affected by the high-temperature steam.

[0021] A portion of the exhaust portion is located in the water tank, so that the exhaust portion occupies a portion of the space in the water tank, the space utilization rate of the interior of the base assembly is improved, and the exhaust portion is prevented from excessively occupying the space outside the water tank.

[0022] In some technical solutions, the base assembly further comprises a flow guide portion provided on the exhaust portion, at least a portion of the isolation air duct is located in the flow guide portion, the side portion of the flow guide portion is provided with a second air outlet, the first air outlet and the second air outlet are in communication through the isolation air duct in the flow guide portion, and the second air outlet and the exhaust port are in communication through the isolation air duct in the flow guide portion.

[0023] The flow guide portion is provided on the exhaust portion, and the air flow discharged from the exhaust portion flows to the exhaust port through the flow guide portion.

[0024] The exhaust portion and the flow guide portion cooperate with each other to form a channel for the air flow to flow out in the interior of the exhaust portion and the flow guide portion. In the case of structural limitation, the exhaust portion is difficult to directly extend to the exhaust port, and the flow guide portion can be provided on the exhaust portion to further guide the air flow. When the air flow is discharged from the flow guide portion, the distance between the air flow and the exhaust port is reduced, the diffusion effect of the air flow in the base assembly is reduced, and the steam is ensured to be discharged from the base assembly at a high flow rate under the driving of the air flow.

[0025] The second air outlet is arranged on the side of the flow guide part, and the steam on the top of the flow guide part is not easy to flow to the second air outlet, so that the difficulty of the steam flowing into the flow guide part is increased, and the steam is prevented from flowing to the fan assembly through the flow guide part.

[0026] Moreover, in the case that the condensed water is formed above the flow guide part, the condensed water is also not easy to enter into the flow guide part, so that the condensed water is prevented from contacting the fan assembly, and the damage rate of the fan assembly is further reduced.

[0027] In some technical solutions, optionally, at least a part of the flow guide part is bent towards the air outlet.

[0028] The air flow can flow to the air outlet in the flow guide part, and at least a part of the flow guide part is bent towards the air outlet, so that the bending structure on the flow guide part can guide the air flow towards the air outlet. Under the guiding action of the flow guide part, the air flow can flow to the air outlet at a high flow rate, so that the air flow is prevented from excessively reducing the flow rate inside the base assembly, and the steam can be ensured to flow out of the base assembly at a high flow rate.

[0029] In some technical solutions, optionally, the base assembly further comprises a surrounding rib arranged on the flow guide part, the number of the surrounding ribs and the flow guide parts are both at least two, the surrounding ribs and the flow guide parts are arranged one by one in a one-to-one correspondence, at least a part of the isolation air duct is located in the surrounding rib, and the second air outlet and the air outlet are connected in communication through the isolation air duct in the surrounding rib.

[0030] The number of the flow guide parts is at least two, and the air flow flowing out of the fan assembly flows to the corresponding surrounding rib through the at least two flow guide parts, and then flows to the air outlet through the surrounding rib.

[0031] The surrounding rib connects the second air outlet and the air outlet in communication, so that the air flow is prevented from excessively diffusing in the base assembly.

[0032] The number of the flow guide parts is at least two, so that even if one flow guide part is blocked, the air flow can still be discharged outward through the other flow guide parts. Moreover, the at least two flow guide parts form multiple air flows, and the multiple air flows can be arranged around the steam discharge position, so that the cooling effect of the air flow on the steam is improved.

[0033] In some technical solutions, optionally, the flow guide part is integrally formed on the air outlet part, or the flow guide part is locked on the air outlet part, and the flow guide part is in sealed contact with the air outlet part.

[0034] The flow guide part and the air outlet part can be arranged as an integrated structure, so that the processing difficulty of the base assembly is reduced. Alternatively, the flow guide part and the air outlet part can be arranged as two independent components, and the flow guide part is locked on the air outlet part or is detached from the air outlet part according to the use requirement of the user.

[0035] In some technical solutions, optionally, the steam flowing back into the water tank flows to the air outlet through the gap between the adjacent two flow guide parts.

[0036] The gap is formed between the two adjacent flow guide parts, and the steam flowing back into the water tank flows to the exhaust port through the gap. The steam flows out of the two flow guide parts on both sides of the steam, which is conducive to improving the cooling and dispersion effect of the steam, and avoiding scalding the user by the steam.

[0037] In some embodiments, the top of the exhaust part is provided with a groove, and the groove is in communication with the gap.

[0038] Since a part of the exhaust part extends into the water tank, a groove can be provided on the exhaust part. The groove connects the inside of the water tank with the gap, and forms a channel for the steam to flow out, ensuring that the steam can flow out stably along the designated channel, avoiding the steam flowing around in the base assembly.

[0039] In some embodiments, the exhaust port includes a first exhaust port and a second exhaust port. The steam flowing back into the water tank is discharged through the first exhaust port, and the airflow blown by the fan assembly is discharged through the second exhaust port.

[0040] The steam is discharged from the base assembly through the first exhaust port, and the air outlet side is in communication with the second exhaust port. The airflow blown by the fan assembly is discharged from the base assembly through the second exhaust port, so that the steam and the airflow are mixed after being discharged from the base assembly, avoiding condensation of the steam inside the base assembly and preventing the formation of condensed water of the steam inside the base assembly.

[0041] In some embodiments, the number of second exhaust ports is multiple, and the multiple second exhaust ports are located on the side of the first exhaust port.

[0042] The multiple second exhaust ports are located on the side of the first exhaust port, so that the first exhaust port and the second exhaust port can be arranged close to each other, and the steam and the airflow discharged outward can be close to each other. The steam discharged from the first exhaust port can effectively mix with the airflow discharged from the second exhaust port, which is conducive to improving the condensation effect of the airflow on the steam and effectively dispersing the steam to avoid the formation of condensed water on the cabinet.

[0043] The multiple second exhaust ports can improve the contact probability of the steam and the airflow, thereby being conducive to improving the condensation and dispersion effect of the airflow on the steam.

[0044] In some embodiments, the multiple second exhaust ports are distributed in the circumferential direction of the first exhaust port.

[0045] The number of second exhaust ports is multiple, and the multiple second exhaust ports are simultaneously in communication with the air outlet side, so that the airflow driven by the fan assembly can be discharged through the multiple second exhaust ports.

[0046] The plurality of second exhaust ports are distributed along the circumference of the first exhaust port, that is, the plurality of second exhaust ports are distributed in a manner of "surrounding" the first exhaust port. When the steam and the airflow are discharged outward, the airflow discharged by the plurality of second exhaust ports surrounds the steam discharged by the first exhaust port, so that the steam around the steam can be effectively mixed with the steam, thereby improving the condensation effect and the dispersion effect on the steam.

[0047] In some embodiments, the plurality of second exhaust ports are distributed in the first direction, and the two sides of the first exhaust port are provided with the second exhaust ports in the first direction.

[0048] The second exhaust ports are distributed on the two sides of the first exhaust port, so that the steam discharged outward is provided with the flowing airflow on both sides, thereby ensuring that the steam can be effectively mixed with the airflow.

[0049] The plurality of second exhaust ports are distributed in the first direction, and the first exhaust port and the second exhaust port are both distributed in the first direction, so that the first exhaust port and the second exhaust port only occupy the space in the first direction, thereby improving the space utilization of the base assembly.

[0050] In a possible application, the first direction is parallel to the side wall of the juice receiving disc, so that the first exhaust port and the second exhaust port are distributed along the side of the juice receiving disc.

[0051] In some embodiments, the first exhaust port and the second exhaust port extend from the side of the base.

[0052] The first exhaust port and the second exhaust port extend from the side of the base, so that the steam is not easy to contact the cooking device during the process of being discharged outward by the first exhaust port, thereby avoiding the formation of condensed water on the cooking device, and reducing the cleaning workload of the user on the cooking device.

[0053] In some embodiments, the opening directions of the first exhaust port and the second exhaust port are both away from the bottom of the base.

[0054] The openings of the first exhaust port and the second exhaust port are upward, so that the steam flows upward when the steam is discharged by the first exhaust port, thereby reducing the probability of the steam contacting the wall surface, avoiding the formation of condensed water on the wall surface, and reducing the workload of the user on the wall surface.

[0055] In some embodiments, the base is provided with an air inlet channel, and the fan assembly inhales external air through the air inlet channel; the base assembly further comprises a controller arranged in the base, and at least a part of the controller is located in the air inlet channel.

[0056] The air inlet channel is arranged on the base, and external gas can be sucked into the mounting cavity through the air inlet channel when the fan assembly is running. The controller generates a large amount of heat during operation, and therefore needs to be cooled. In the scheme, at least a part of the controller is arranged in the air inlet channel, and the airflow flowing in the air inlet channel passes through the controller, thereby cooling the controller and ensuring stable operation of the controller.

[0057] The fan assembly can not only disperse the steam discharged outward, but also cool the controller, and one fan assembly plays a dual role, so that an additional cooling fan for the controller is not needed, the number of fans for cooling in the base assembly is reduced, the space occupation in the base assembly is reduced, and the cost of the scheme is lower in a device with the same function.

[0058] In some technical solutions, optionally, the base comprises: a base body, the water tank is located in the base body; a condensing component is located in the water tank, the heating element is used to heat water in the condensing component to generate steam; a juice receiving disc is located at the top of the water tank, the juice receiving disc is provided with a steam return port, and the steam in the cooking cavity flows back to the water tank through the steam return port.

[0059] The cooking cavity is located above the juice receiving disc, and the juice receiving disc is used to receive and collect juice flowing from the food material during cooking, so that the user can conveniently collect the juice flowing from the food material, and the use convenience of the user for the cooking equipment is improved. The steam in the cooking cavity flows back to the water tank through the steam return port on the juice receiving disc.

[0060] The condensing component is arranged in the water tank, the heating element can heat the water in the condensing component, a small amount of water in the condensing component can be quickly heated, and the steam generation speed is improved. The steam flowing back to the water tank flows between the condensing component and the water tank, so that the steam is prevented from mixing with the steam generated in the condensing component.

[0061] In some technical solutions, optionally, the exhaust port is arranged on the juice receiving disc.

[0062] The exhaust port is arranged on the juice receiving disc, so that the structure of the exhaust port does not need to be processed on other components, and the machining difficulty of the base assembly is reduced.

[0063] In the second aspect, the utility model provides a kind of cooking equipment, comprising: shell, shell is equipped with cooking cavity;As in the base component of first aspect, shell is equipped on base component.

[0064] In some technical solutions, optionally, the shell is provided with a steam return channel, one end of the steam return channel extends towards the top of the shell, the other end of the steam return channel communicates with the water tank, and the steam in the cooking cavity flows into the water tank through the steam return channel.

[0065] After the steam flows into the cooking cavity, the steam rises in the cooking cavity, and in the case that the steam flows to the top of the cooking cavity, the steam flows into the steam backflow channel. In the case that part of the steam flows to the top of the cooking cavity, the steam substantially fills the cooking cavity, so that the temperature is high everywhere in the cooking cavity, ensuring the uniform and hot effect of the steam on the food materials. The steam backflows into the water tank through the steam backflow channel for condensation, so that an opening for discharging steam does not need to be arranged on the shell, avoiding scalding the user.

DETAILED DESCRIPTION

[0084] In order to more clearly understand the above purpose, features and advantages of the present application, the present application will be further described in detail below with reference to 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.

[0085] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0086] The following description refers to the accompanying drawings. Figures 1 to 14 The base assembly and the cooking equipment provided according to some embodiments of the present application are described.

[0087] In combination with Figure 1 , Figure 2 , Figure 5 , Figure 6 ,Figure 7 and Figure 8 As shown in FIGS. 1 to 3, in some embodiments of the utility model, a base assembly 100 is provided, the base assembly 100 is used for cooking equipment, the cooking equipment includes a cooking cavity 210, and the base assembly 100 is provided with an exhaust port 149. The base assembly 100 includes a base 110, a water tank 120, a heating piece 130 and a fan assembly 150. The water tank 120 is located in the base 110, the heating piece 130 is arranged on the water tank 120, and the heating piece 130 is used for heating water in the water tank 120 to provide steam into the cooking cavity 210. The fan assembly 150 is arranged in the base 110, the air outlet side 151 of the fan assembly 150 is communicated with the exhaust port 149, and the airflow blown by the fan assembly 150 and the steam flowing back to the water tank 120 from the cooking cavity 210 are discharged through the exhaust port 149.

[0088] The heating piece 130 is used for heating water in the water tank 120 to generate steam, and the steam can be discharged into the cooking cavity 210, so that the food in the cooking cavity 210 can be heated.

[0089] As the amount of steam in the cooking cavity 210 gradually increases, the steam in the cooking cavity 210 can flow back to the water tank 120, and since water is stored in the water tank 120, the steam flowing into the water tank 120 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The heat of the high-temperature steam is transferred to the water, thereby realizing the recovery of the heat of the steam and avoiding the waste of the heat of the steam. After the steam exchanges heat with the water, the temperature of the steam can also be reduced, thereby avoiding scalding of the user by the discharged steam.

[0090] When the fan assembly 150 operates, the fan assembly 150 drives the airflow to be discharged through the air outlet side 151, the air outlet side 151 is communicated with the exhaust port 149, so that the airflow discharged from the air outlet side 151 flows to the exhaust port 149, and the steam flowing back to the water tank 120 is also discharged outward through the exhaust port 149, and the airflow and the steam can be mixed and discharged at the exhaust port 149.

[0091] Since the temperature of the airflow driven by the fan assembly 150 is lower than the temperature of the steam, the airflow discharged from the exhaust port 149 can condense the steam and quickly disperse the steam, the mixed gas quickly flows and diffuses, the contact area between the steam and the surrounding air is large, the water molecules in the steam quickly mix with the air, and it is difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules gathering in a certain place, thereby avoiding the formation of condensed water. When the cooking equipment operates, it is not easy to form condensed water on the cabinet, thereby reducing the workload of the user for cleaning around the cooking equipment.

[0092] In the embodiment, the steam does not need to pass through the inside of the fan assembly 150, the fan assembly 150 does not need to be high-temperature and high-humidity resistant, and the cost is lower.

[0093] Figure 2 In the diagram, solid arrows indicate the flow path of steam flowing into the cooking chamber 210, dashed arrows indicate the flow path of steam returning to the cooking chamber 210, and curved arrows indicate the direction of airflow driven by the fan assembly 150.

[0094] Figure 5 In the image, the arrow indicates the direction of the airflow drawn into the fan assembly 150.

[0095] Figure 6 In the image, the arrow indicates the direction of airflow driven by the fan assembly 150.

[0096] Figure 8 In the diagram, the arrow at the first exhaust port 141 indicates the direction of steam discharge, and the arrow at the second exhaust port 142 indicates the direction of airflow discharge.

[0097] Combination Figure 2 and Figure 5 As shown, in some embodiments, optionally, the air outlet side 151 of the fan assembly 150 is independent of the interior of the water tank 120.

[0098] In this design, the air outlet side 151 and the interior of the water tank 120 are set independently. During the outward flow of steam in the water tank 120, the steam will not pass through the air outlet side 151 of the fan assembly 150, further reducing the impact of high-temperature steam on the fan assembly 150.

[0099] When the fan assembly 150 is running, the airflow can prevent steam from flowing into the fan assembly 150. Since the air outlet side 151 and the water tank 120 are set independently, even if the fan assembly 150 is in a stopped state, the steam in the water tank 120 is not easy to enter the fan assembly 150, thus reducing the damage rate of the fan assembly 150.

[0100] Combination Figure 2 , Figure 6 , Figure 7 and Figure 9 As shown, in some embodiments, optionally, an isolation duct 180 is provided between the air outlet side 151 of the fan assembly 150 and the water tank 120. The airflow blown out by the fan assembly 150 flows to the exhaust port 149 through the isolation duct 180. The isolation duct 180 is used to separate the airflow blown out by the fan assembly 150 from the steam.

[0101] The isolation air duct 180 is arranged between the water tank 120 and the air outlet side 151. The air outlet side 151 is in communication with the isolation air duct 180. The air flow blown by the fan assembly 150 flows to the air outlet 149 through the isolation air duct 180. The steam in the water tank 120 flows to the air outlet 149 outside the isolation air duct 180, avoiding flowing through the air outlet side 151, thereby reducing the damage rate of the fan assembly 150.

[0102] Figure 7 The arrows are used to represent the flow direction of the air flow blown by the fan assembly 150 to the outside of the base 110.

[0103] In some embodiments, one end of the isolation air duct 180 extends to the air outlet 149, or one end of the isolation air duct 180 is arranged in a spaced manner with the air outlet 149. The air flow discharged from the isolation air duct 180 mixes with the steam and then flows to the air outlet 149.

[0104] The isolation air duct 180 can extend to the air outlet 149, so that the air flow discharged from the fan assembly 150 directly flows to the air outlet 149 through the isolation air duct 180. The air flow cannot flow into the inside of the base assembly 100. The air flow and the steam can only mix at the air outlet 149. The air flow cools and disperses the steam at the air outlet 149.

[0105] Alternatively, the isolation air duct 180 does not directly extend to the air outlet 149, that is, a gap is left between the isolation air duct 180 and the air outlet 149. After the air flow discharged from the fan assembly 150 flows out of the isolation air duct 180, the air flow mixes with the steam in the base assembly 100 and then flows to the air outlet 149. The steam has been cooled in advance inside the base assembly 100 when flowing through the air outlet 149. Even if the user's hand contacts the air outlet 149, it is not easy to be scalded by the steam, further improving the safety of the user when using the cooking device.

[0106] In combination with FIGS. 1-3, Figure 2 , Figure 6 , Figure 7 and Figure 12 In some embodiments, the base assembly 100 further comprises an air exhaust portion 122. At least a portion of the air exhaust portion 122 extends into the water tank 120. The air exhaust portion 122 is provided with a first air outlet 123. The first air outlet 123 is in communication with the air outlet 149. At least a portion of the isolation air duct 180 is located in the air exhaust portion 122. The air outlet side 151 of the fan assembly 150 and the air outlet 149 are in communication through the isolation air duct 180 in the air exhaust portion 122.

[0107] The water tank 120 is provided with an exhaust part 122, and the air flow blown by the fan assembly 150 is discharged outward through the exhaust part 122. The exhaust part 122 serves as a structure for separating the air flow and the steam, so that the air flow flows to the exhaust port 149 in the exhaust part 122, and the steam is prevented from flowing through the fan assembly 150, thereby preventing the fan assembly 150 from being affected by the high-temperature steam.

[0108] Part of the exhaust part 122 is located in the water tank 120, so that the exhaust part 122 occupies part of the space in the water tank 120, thereby improving the space utilization rate inside the base assembly 100 and preventing the exhaust part 122 from occupying too much space outside the water tank 120.

[0109] In the embodiment, the exhaust part 122 is integrally arranged with the water tank 120, and in other embodiments, the exhaust part 122 can also be installed in the water tank 120.

[0110] In combination with FIGS. Figure 2 , Figure 6 , Figure 7 and Figure 12 , in some embodiments, the base assembly 100 further comprises a flow guide part 190, which is arranged on the exhaust part 122, and at least part of the isolation air duct 180 is located in the flow guide part 190. The side of the flow guide part 190 is provided with a second air outlet 191. The first air outlet 123 and the second air outlet 191 are connected in communication through the isolation air duct 180 in the flow guide part 190, and the second air outlet 191 and the exhaust port 149 are connected in communication through the isolation air duct 180 in the flow guide part 190.

[0111] The flow guide part 190 is arranged on the exhaust part 122, and the air flow flowing out of the exhaust part 122 flows to the exhaust port 149 through the flow guide part 190.

[0112] The exhaust part 122 and the flow guide part 190 cooperate with each other to form a channel for the air flow to flow out of the exhaust part 122 and the flow guide part 190. In the case of structural limitation, the exhaust part 122 is difficult to directly extend to the exhaust port 149. The flow guide part 190 can be arranged on the exhaust part 122 to further guide the air flow. When the air flow is discharged from the flow guide part 190, the distance between the air flow and the exhaust port 149 is reduced, the diffusion effect of the air flow in the base assembly 100 is reduced, and the steam is discharged from the base assembly 100 at a high flow rate under the driving of the air flow.

[0113] The second air outlet 191 is arranged on the side of the flow guide part 190, and the steam at the top of the flow guide part 190 is not easy to flow to the second air outlet 191, thereby increasing the difficulty of the steam flowing into the flow guide part 190 and preventing the steam from flowing to the fan assembly 150 through the flow guide part 190.

[0114] Furthermore, even if condensation forms above the guide section 190, the condensation is less likely to enter the guide section 190, thus preventing the condensation from contacting the fan assembly 150 and further reducing the damage rate of the fan assembly 150.

[0115] Combination Figure 6 and Figure 7 As shown, in some embodiments, optionally, at least a portion of the guide portion 190 is bent toward the exhaust port 149.

[0116] Airflow can flow towards exhaust port 149 within guide section 190, bending at least a portion of guide section 190 towards exhaust port 149, so that the bending structure on guide section 190 can guide airflow towards exhaust port 149. Under the guiding effect of guide section 190, airflow can flow towards exhaust port 149 at a higher velocity, avoiding excessive reduction in airflow velocity inside base assembly 100, and ensuring that airflow can carry steam out of base assembly 100 at a higher velocity.

[0117] Combination Figure 2 , Figure 6 , Figure 7 , Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the base assembly 100 may optionally include: a surrounding rib 143, the surrounding rib 143 covering the airflow guide 190, the number of surrounding ribs 143 and airflow guide 190 being at least two, the surrounding ribs 143 and airflow guide 190 being arranged in a one-to-one correspondence, at least a portion of the isolation air duct 180 being located within the surrounding rib 143, and the second air outlet 191 and the exhaust outlet 149 being connected through the isolation air duct 180 within the surrounding rib 143.

[0118] The number of guide sections 190 is at least two. The airflow from the fan assembly 150 flows through at least two guide sections 190 into the corresponding ribs 143, and then flows through the ribs 143 to the exhaust port 149.

[0119] The surrounding rib 143 connects the second air outlet 191 and the exhaust outlet 149 to prevent excessive airflow diffusion within the base assembly 100.

[0120] The number of guide sections 190 is at least two, so that even if one guide section 190 is blocked, the airflow can still be discharged outward through the other guide sections 190. Moreover, the at least two guide sections 190 form multiple airflows, which can be arranged around the steam discharge position to improve the cooling effect of the airflow on the steam.

[0121] In some embodiments, the guide portion 190 may be integrally formed on the exhaust portion 122, or the guide portion 190 may be locked onto the exhaust portion 122, and the guide portion 190 may be in sealed contact with the exhaust portion 122.

[0122] The flow guide part 190 and the exhaust part 122 can be arranged as an integrated structure to reduce the processing difficulty of the base assembly 100. Alternatively, the flow guide part 190 and the exhaust part 122 can be arranged as two independent components. According to the use requirement of the user, the flow guide part 190 can be locked on the exhaust part 122, or the flow guide part 190 can be detached and only the exhaust part 122 is used.

[0123] In combination with Figure 2 , Figure 6 , Figure 9 and Figure 12 , in some embodiments, optionally, the steam flowing back into the water tank 120 flows to the exhaust port 149 through the gap 192 between two adjacent flow guide parts 190.

[0124] The gap 192 is formed between two adjacent flow guide parts 190, and the steam flowing back into the water tank 120 flows to the exhaust port 149 through the gap 192. The airflow discharged from the two flow guide parts 190 is on both sides of the steam, which is beneficial to improve the cooling and dispersion effect of the steam and avoid scalding the user by the steam.

[0125] In combination with Figure 2 , Figure 6 , Figure 9 and Figure 12 , in some embodiments, optionally, the top of the exhaust part 122 is provided with a groove 124, and the groove 124 is in communication with the gap 192.

[0126] Since a part of the exhaust part 122 extends into the water tank 120, the groove 124 can be arranged on the exhaust part 122. The groove 124 connects the inside of the water tank 120 with the gap 192. The groove 124 forms a channel for the steam to flow out, which ensures that the steam can stably flow out along the designated channel and avoids the steam flowing everywhere in the base assembly 100.

[0127] In combination with Figure 2 , Figure 8 , Figure 10 and Figure 11 , in some embodiments, optionally, the exhaust port 149 includes a first exhaust port 141 and a second exhaust port 142. The steam flowing back into the water tank 120 is discharged through the first exhaust port 141, and the airflow blown by the fan assembly 150 is discharged through the second exhaust port 142.

[0128] The steam is discharged from the base assembly 100 through the first exhaust port 141. The air outlet side 151 is in communication with the second exhaust port 142. The airflow blown by the fan assembly 150 is discharged from the base assembly 100 through the second exhaust port 142. The steam and the airflow are mixed after being discharged from the base assembly 100, which avoids the condensation of the steam inside the base assembly 100 and prevents the formation of condensed water of the steam inside the base assembly 100.

[0129] In combination Figure 2 and Figure 5 As shown in FIG. 1, in some embodiments, the base 110 optionally comprises a base body 112, a condensing component 170, and a juice receiving disc 140, the water tank 120 is located in the base body 112, the condensing component 170 is located in the water tank 120, and the heating element 130 is used to heat the water in the condensing component 170 to generate steam. The juice receiving disc 140 is located at the top of the water tank 120, and the juice receiving disc 140 is provided with a steam return port 144, and the steam in the cooking cavity 210 returns to the water tank 120 and the condensing component 170 through the steam return port 144.

[0130] The cooking cavity 210 is located above the juice receiving disc 140, and the juice receiving disc 140 is used to collect the juice flowing from the food during cooking, which facilitates the user to concentrate on the juice flowing from the food, and is beneficial to improve the user's convenience in using the cooking equipment. The steam in the cooking cavity 210 returns to the water tank 120 through the steam return port 144 on the juice receiving disc 140.

[0131] The condensing component 170 is arranged in the water tank 120, and the heating element 130 can heat the water in the condensing component 170, and a small part of the water in the condensing component 170 can be quickly heated, which is beneficial to improve the steam generation speed. The steam returning to the water tank 120 flows into the condensing component 170 and the water tank 120, avoiding mixing of the steam with the steam generated in the condensing component 170.

[0132] The surrounding rib 143 is arranged at the bottom of the juice receiving disc 140, and in the embodiment, the surrounding rib 143 is integrally arranged with the juice receiving disc 140. In other embodiments, the surrounding rib 143 can also be installed at the bottom of the juice receiving disc 140.

[0133] Figure 12 In FIG. 1, the arrows are used to represent the steam flow direction returning to the cooking cavity 210.

[0134] In some embodiments, the exhaust port 149 is arranged on the juice receiving disc 140.

[0135] The exhaust port 149 is arranged on the juice receiving disc 140, so that the structure of the exhaust port 149 does not need to be processed on other components, which is beneficial to reduce the processing difficulty of the base assembly 100.

[0136] The heating piece 130 is fixed at the bottom of the water tank 120, the energy-gathering component 170 is located in the water tank 120, and the energy-gathering component 170 is located above the heating piece 130. The energy-gathering component 170 comprises an inner cylinder 174 and an outer cylinder 175, the inner cylinder 174 and the outer cylinder 175 are connected, the inner cylinder 174 is located inside the outer cylinder 175, a steam port 171 is arranged on the inner cylinder 174, and steam in the inner cylinder 174 flows to the cooking cavity 210 through the steam port 171. The space inside the inner cylinder 174 serves as a heating cavity 172, and the inner cavity of the outer cylinder 175 is in communication with the water tank 120. For example, a hole can be formed in the outer cylinder 175, or a notch is arranged at the bottom of the outer cylinder 175, so that water in the water tank 120 can be supplemented into the outer cylinder 175, and a hole is formed at the bottom of the inner cylinder 174, so that water in the outer cylinder 175 can be supplemented into the inner cylinder 174. The heating piece 130 can heat the water in the heating cavity 172. Since the space in the inner cylinder 174 is small, a small amount of water in the inner cylinder 174 can be quickly heated into steam, thereby improving the steam generation speed.

[0137] It should be noted that the space surrounded by the water tank 120, the energy-gathering component 170 and the juice receiving disc 140 is defined as the reflux channel 128, the steam flowing back from the cooking cavity 210 into the water tank 120 enters the reflux channel 128, the reflux channel 128 is part of the space in the water tank 120, and the steam in the reflux channel 128 is discharged through the first exhaust port 141.

[0138] In a possible application, the juice receiving disc 140 is placed on the energy-gathering component 170 and / or the water tank 120.

[0139] As shown in the drawings, Figure 3 In a possible application, in order to ensure that the steam generated in the energy-gathering component 170 enters the cooking cavity 210, the position between the juice receiving disc 140 and the energy-gathering component 170 needs to be sealed to prevent a part of the steam from flowing into the space between the energy-gathering component 170 and the water tank 120 without entering the cooking cavity 210. In this scheme, a first groove 173 is arranged at the top of the energy-gathering component 170, the first groove 173 is distributed along the circumference of the energy-gathering component 170, that is, the first groove 173 has a ring structure. The bottom of the juice receiving disc 140 is provided with a first supporting rib 146, the first supporting rib 146 extends into the first groove 173, and the first supporting rib 146 is distributed along the circumference of the juice receiving disc 140, so the first supporting rib 146 also has a ring structure.

[0140] In the cooking process, the steam encounters the juice receiving disc 140 to form condensed water, and part of the condensed water will drip into the first groove 173. When the condensed water in the first groove 173 is higher than the bottom of the first supporting rib 146, a water seal is formed between the juice receiving disc 140 and the energy concentrating component 170, which can block the steam and prevent the newly generated steam from directly flowing between the energy concentrating component 170 and the water tank 120, so as to ensure that the steam can smoothly enter the cooking cavity 210 and improve the heating efficiency of the steam on the food material. The first supporting rib 146 and the first groove 173 are arranged between the juice receiving disc 140 and the energy concentrating component 170 to realize the sealing between the juice receiving disc 140 and the energy concentrating component 170 through the water seal. Compared with the soft rubber sealing method, one sealing component is saved in the present application, so that the structure of the base assembly 100 is simpler, the cost is reduced, and the assembly difficulty of the base assembly 100 is reduced.

[0141] As shown in Figure 4 In a possible application, the top of the water tank 120 is provided with a second groove 129 along the circumference of the water tank 120, and the bottom of the juice receiving disc 140 is provided with a second supporting rib 147 which extends into the second groove 129.

[0142] In order to avoid the steam being discharged to the outside through the juice receiving disc 140 and the water tank 120, the position between the juice receiving disc 140 and the water tank 120 needs to be sealed. In the present application, the second groove 129 is arranged on the top of the water tank 120, and the second groove 129 is distributed along the circumference of the water tank 120, that is, the second groove 129 has a ring structure. The bottom of the juice receiving disc 140 is provided with the second supporting rib 147 which extends into the second groove 129, and the second supporting rib 147 is distributed along the circumference of the juice receiving disc 140, so that the second supporting rib 147 also has a ring structure.

[0143] In the cooking process, the steam encounters the juice receiving disc 140 to form condensed water, and part of the condensed water will drip into the second groove 129. When the condensed water in the second groove 129 is higher than the bottom of the second supporting rib 147, a water seal is formed between the juice receiving disc 140 and the water tank 120, which can block the steam and prevent the steam flowing back to the water tank 120 from being discharged between the juice receiving disc 140 and the water tank 120. The second supporting rib 147 and the second groove 129 are arranged between the juice receiving disc 140 and the water tank 120 to realize the sealing between the juice receiving disc 140 and the water tank 120 through the water seal. Compared with the soft rubber sealing method, one sealing component is saved in the present application, so that the structure of the base assembly 100 is simpler, the cost is reduced, and the assembly difficulty of the base assembly 100 is reduced.

[0144] As shown in Figure 5As shown, in one possible application, the fan assembly 150 includes a fan 152 and a mounting base 153, with the mounting base 153 located within the base 110 and the fan 152 mounted within the mounting base 153. The inlet side 154 and outlet side 151 of the fan 152 can be disposed on the mounting base 153, and external airflow is drawn into the fan 152 through the inlet side 154.

[0145] Combination Figure 2 , Figure 6 , Figure 8 and Figure 11 As shown, in some embodiments, optionally, there are multiple second exhaust ports 142, and the multiple second exhaust ports 142 are located on the side of the first exhaust port 141.

[0146] Multiple second exhaust ports 142 are located on the side of the first exhaust port 141, so that the first exhaust port 141 and the second exhaust port 142 can be set close to each other, and the steam and airflow discharged outward can be close to each other. The steam discharged from the first exhaust port 141 can effectively mix with the airflow discharged from the second exhaust port 142, which is beneficial to improve the condensation effect of the airflow on the steam, and can also effectively disperse the steam to prevent the steam from forming condensation on the cabinet.

[0147] The multiple streams of air discharged from the multiple second exhaust ports 142 can increase the probability of contact between steam and airflow, thereby improving the condensation and dispersion effect of the airflow on the steam.

[0148] Combination Figure 2 , Figure 6 and Figure 14 As shown, in some embodiments, optionally, there are multiple second exhaust ports 142, and the multiple second exhaust ports 142 are located circumferentially around the first exhaust port 141. Figure 14 The arrow at point H points upwards.

[0149] There are multiple second exhaust ports 142, and multiple second exhaust ports 142 are simultaneously connected to the air outlet side 151, so that the airflow driven by the fan assembly 150 can be discharged through multiple second exhaust ports 142.

[0150] Multiple second exhaust ports 142 are distributed around the first exhaust port 141, that is, multiple second exhaust ports 142 are distributed in a way that "surrounds" the first exhaust port 141. When steam and airflow are discharged outward, the airflow discharged from multiple second exhaust ports 142 surrounds the steam discharged from the first exhaust port 141. Even if the discharged steam spreads in all directions, the airflow around the steam can effectively mix with the steam, which is beneficial to improving the condensation and dispersing effect of the steam.

[0151] Combination Figure 2 , Figure 6 , Figure 11 andFigure 13 As shown, in some embodiments, optionally, there are multiple second exhaust ports 142, and the multiple second exhaust ports 142 are distributed in a first direction, along the first direction ( Figure 13 (The arrow at point D points to) Second exhaust ports 142 are provided on both sides of the first exhaust port 141.

[0152] Second exhaust ports 142 are distributed on both sides of the first exhaust port 141, so that airflow is provided on both sides of the steam discharged outward, ensuring that the steam can be effectively mixed with the airflow.

[0153] Multiple second exhaust ports 142 are distributed along the first direction, and both the first exhaust port 141 and the second exhaust port 142 are distributed in the first direction. Therefore, the first exhaust port 141 and the second exhaust port 142 will only occupy the space in the first direction, which is beneficial to improving the space utilization rate on the base assembly 100.

[0154] In one possible application, the first direction is parallel to the side wall of the juice tray 140, such that the first vent 141 and the second vent 142 are distributed along the side of the juice tray 140.

[0155] Figure 8 In the middle, a second exhaust port 142 is provided on both the left and right sides of the first exhaust port 141.

[0156] Combination Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the first exhaust port 141 and the second exhaust port 142 extend out of the side of the base 110.

[0157] The first exhaust port 141 and the second exhaust port 142 extend from the side of the base 110. During the process of releasing steam through the first exhaust port 141, the steam is less likely to come into contact with the cooking equipment, thereby avoiding the formation of condensation on the cooking equipment and reducing the amount of cleaning work for the user.

[0158] like Figure 8 As shown, in some embodiments, optionally, the opening directions of the first exhaust port 141 and the second exhaust port 142 are ( Figure 8 The arrows at point E point point away from the bottom of the base 110.

[0159] The openings of the first exhaust port 141 and the second exhaust port 142 face upwards. When steam is discharged from the first exhaust port 141, the steam will flow upwards, which can reduce the chance of steam contacting the wall surface, thereby avoiding the formation of condensation on the wall surface and reducing the amount of work that users need to do to clean the wall surface.

[0160] Combination Figure 2 andFigure 5 As shown in some embodiments, the base 110 is optionally provided with an air inlet channel 111, and the fan assembly 150 draws external air through the air inlet channel 111. The base assembly 100 further comprises a controller 160, which is arranged in the base 110, and at least a portion of the controller 160 is located in the air inlet channel 111.

[0161] The air inlet channel 111 is arranged on the base 110, and when the fan assembly 150 is running, external air can be drawn into the installation cavity through the air inlet channel 111. The controller 160 generates a large amount of heat during operation, and therefore needs to be cooled. In this scheme, at least a portion of the controller 160 is arranged in the air inlet channel 111, and the airflow flowing in the air inlet channel 111 passes through the controller 160, thereby cooling the controller 160 and ensuring stable operation of the controller 160.

[0162] The fan assembly 150 can not only disperse the steam discharged outward, but also cool the controller 160, and one fan assembly 150 plays a dual role. Therefore, it is not necessary to additionally arrange a cooling fan for the controller 160, the number of fans for cooling in the base assembly 100 is reduced, the space occupation in the base assembly 100 is reduced, and the cost of the device with the same function is lower.

[0163] In combination with Figure 1 and Figure 2 As shown in some embodiments of the utility model, a cooking device is provided, which comprises a shell 200 and the base assembly 100 in any of the above embodiments, the shell 200 is provided with a cooking cavity 210, and the shell 200 is arranged on the base assembly 100. The cooking device in this embodiment can realize the technical effects in any of the above embodiments, and details are not repeated here.

[0164] The shell 200 comprises an outer shell 220, a partition plate 240 and a cover 230, the outer shell 220 is arranged on the juice receiving disc 140, the cover 230 is arranged on the top wall of the outer shell 220, and the partition plate 240 is arranged in the outer shell 220. The number of partition plates 240 can be multiple, and exemplarily, the number of partition plates 240 in this embodiment is two, one partition plate 240 is arranged above the juice receiving disc 140, and the other is arranged on the upper half of the outer shell 220, and the partition plate 240 is used for supporting food or tableware. In other embodiments, the number of partition plates 240 can be increased to increase the number of layers of space for placing food.

[0165] In a possible application, the cooking device can be a steamer, an electric rice cooker, a steaming oven, etc.

[0166] In combination with Figure 2 and Figure 9As shown, in some embodiments, the steam return channel 300 is optionally arranged in the housing 200, one end of the steam return channel 300 extends towards the top of the housing 200, and the other end of the steam return channel 300 is in communication with the water tank 120, and the steam in the cooking cavity 210 flows to the water tank 120 through the steam return channel 300.

[0167] After the steam flows into the cooking cavity 210, the steam rises in the cooking cavity 210, and in the case that the steam flows to the top of the cooking cavity 210, the steam flows into the steam return channel 300. In the case that part of the steam flows to the top of the cooking cavity 210, the steam substantially fills the cooking cavity 210, so that the temperature of each part of the cooking cavity 210 is relatively high, which ensures the uniform and hot effect of the steam on the food. The steam returns to the water tank 120 through the steam return channel 300 for condensation, so that there is no need to arrange an opening for discharging steam on the housing 200, thereby avoiding scalding the user.

[0168] Figure 9 In the drawings, the arrows in the isolation air duct represent the flow direction of the air flow, and the arrows in the steam return channel 300 represent the flow direction of the steam returning to the cooking cavity 210.

[0169] Exemplarily, the steam return channel 300 is a tubular structure arranged in the housing 200, or the steam return channel 300 is integrally arranged in the housing 200.
