Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and more specifically, to a base assembly and a cooking equipment. Background Art

[0002] During the cooking process, cooking equipment generates a large amount of high-temperature steam. When the high-temperature steam is discharged into the indoor space, users are easily scalded by the high-temperature steam, resulting in poor safety during the cooking process. Summary of the Utility Model

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

[0004] In view of this, in a first aspect, the utility model provides a base assembly for a cooking equipment. The cooking equipment has a cooking cavity. The base assembly includes: a box body having a steam inlet, a steam outlet, and a liquid storage cavity. The steam inlet is also used to communicate with the cooking cavity; a flow guide member connected to the box body and located in the liquid storage cavity. The flow guide member is provided with a steam flow channel, and both the steam inlet and the steam outlet are communicated with the steam flow channel; wherein, a highest liquid level line is provided on the liquid storage cavity. Based on the bottom wall of the liquid storage cavity as a reference plane, both the steam inlet and the steam outlet are higher than the highest liquid level line.

[0005] For the base assembly provided by the utility model, a steam inlet is provided on the box body, and the steam inlet is used to communicate with the cooking cavity. Therefore, the steam in the cooking cavity can flow into the box body through the steam inlet. A steam flow channel is provided on the flow guide member, and one end of the steam flow channel is communicated with the steam inlet. The steam in the cooking cavity can flow into the steam flow channel from one end of the steam flow channel. Since the steam flow channel is communicated with the liquid storage cavity and there is water in the liquid storage cavity, the steam flowing into the steam flow channel can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam flow channel is also communicated with the steam outlet. The steam in the steam flow channel that has been cooled by heat exchange can be discharged from the box body. Since the temperature of the steam discharged from the box body is relatively low, users around the cooking equipment are not easily scalded by the steam, which is beneficial to improving the safety of users during the cooking process.

[0006] In addition, according to the above technical solution of the base assembly provided by the utility model, the following additional technical features may also be included:

[0007] In some technical solutions, optionally, the steam flow channel is communicated with the liquid storage cavity, and the steam flowing into the steam flow channel is used to exchange heat with the water in the liquid storage cavity.

[0008] The flow guide member is used to extend into the liquid storage cavity, and the steam flowing back into the steam flow channel is used to contact and exchange heat with the water in the liquid storage cavity.

[0009] In a possible application, a part of the flow guide member is immersed in the water in the water supply area, so that the water can exchange heat with the flow guide member. When steam flows in the steam flow path, the steam can indirectly exchange heat with the water through the flow guide member.

[0010] Alternatively, an opening is provided at the bottom of the flow guide member, so that the steam flow path in the flow guide member is in direct contact with the water, thereby enabling the steam to directly exchange heat with the water. A part of the flow guide member is immersed in the water, and the water acts as a barrier to the steam, ensuring that the steam can only flow in the steam flow path and is not likely to flow out of the steam flow path. That is, it can ensure that the steam can stably exchange heat with the water and can also ensure that the steam flow path can stably guide the steam.

[0011] In some technical solutions, optionally, the base assembly further includes: an evaporation cover located in the liquid storage cavity. A steam generation cavity is provided in the evaporation cover, and the steam generation cavity is communicated with the liquid storage cavity. A steam supply port is provided on the box body, and the steam generated in the steam generation cavity is discharged into the cooking cavity through the steam supply port.

[0012] An evaporation cover is provided in the liquid storage cavity. The evaporation cover can separate the steam supply port and the steam flow path, so that the steam flowing to the steam supply port and the steam in the steam flow path are not likely to mix with each other. Therefore, the steam generated by the heated water is not likely to flow to the steam flow path, and the steam flowing back into the steam flow path is not likely to be discharged into the cooking cavity again, ensuring that the steam flowing into the cooking cavity and the steam flowing back into the steam flow path are two parts of steam that are approximately independent of each other, avoiding the steam flowing back into the steam flow path from reducing the temperature of the newly generated steam, and thus can ensure the heating speed of the food ingredients.

[0013] A steam generation cavity is provided in the evaporation cover. The steam generation cavity is communicated with the steam supply port. The water in the steam generation cavity will generate steam after being heated, and the steam in the steam generation cavity is discharged into the cooking cavity through the steam supply port. The evaporation cover can define a steam generation cavity, and the amount of water stored in the steam generation cavity is small. Therefore, the small amount of water in the steam generation cavity can be quickly heated into steam, which is beneficial to improving the steam generation speed and further beneficial to improving the heating effect on the food ingredients.

[0014] The steam generation cavity is communicated with the liquid storage cavity, so that the liquid storage cavity can supply water to the steam generation cavity to avoid the problem of dry burning.

[0015] In some technical solutions, optionally, the steam inlet is adjacent to the side of the box body, and a steam supply port is provided in the middle of the side of the box body facing the cooking cavity.

[0016] The steam inlet and the steam outlet are arranged on the side of the box body, and the steam supply port is arranged at the middle position of the top of the box body, so as to keep the steam inlet away from the steam supply port, prevent the steam discharged from the steam supply port from directly flowing towards the steam inlet, ensure that the steam can fill the cooking cavity, and improve the cooking effect on the ingredients.

[0017] In some technical solutions, optionally, the steam flow channels are distributed circumferentially along the evaporation hood.

[0018] The circumferential distribution of the steam flow channels along the evaporation hood enables the steam flow channels to avoid the evaporation hood, and the steam flow channels can also be bent circumferentially along the evaporation hood, which is beneficial to increasing the length of the steam flow channels, prolonging the circulation time of the steam in the steam flow channels, and improving the heat exchange effect between the steam and the water.

[0019] In some technical solutions, optionally, the bottom of the guiding member is spaced from the inner wall of the liquid storage cavity, and the bottom of the guiding member is higher than the bottom of the evaporation hood.

[0020] The bottom of the guiding member is not attached to the inner wall of the liquid storage cavity, so the water can flow at the bottom of the guiding member. Since the bottom of the guiding member is higher than the bottom of the evaporation hood, the guiding member will not obstruct the water flowing towards the evaporation hood, thus ensuring that the water in the liquid storage cavity can be smoothly replenished into the steam generation cavity.

[0021] In some technical solutions, optionally, along the extension direction of the steam flow channel, the length L of the steam flow channel is greater than or equal to 1000 mm.

[0022] The greater the length of the steam flow channel, the longer the flow time of the steam in the steam flow channel, thereby increasing the heat exchange time between the steam and the water and improving the heat recovery effect.

[0023] In some technical solutions, optionally, the width W of the steam flow channel satisfies W≥5 mm.

[0024] The greater the width of the steam flow channel, the larger the heat exchange area between the steam and the water, which is beneficial to improving the heat recovery efficiency.

[0025] In some technical solutions, optionally, the base assembly further includes: a fan, which is connected to the box body, and the fan is used to pump the steam in the steam flow channel towards the steam outlet.

[0026] When the fan operates, it is used to pump the steam in the steam flow channel towards the steam outlet. Driven by the fan, the steam is discharged to the outside of the cooking device at a relatively high flow rate. 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 condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules aggregating in a certain place, thus avoiding the formation of condensed water.

[0027] In some technical solutions, optionally, an installation cavity is provided on the box body, the steam flow channel is communicated with the steam outlet through the installation cavity, and the fan is located in the installation cavity.

[0028] An installation cavity is provided on the box body. The installation cavity is used to install the fan and to communicate the steam flow channel and the steam outlet. By arranging the fan in the installation cavity, the air flow flowing into the installation cavity basically comes from the steam flow channel, and it is not easy for the fan to extract the air inside the box body and outside the steam flow channel, so as to ensure that the steam in the steam flow channel is discharged at a higher flow rate, and further avoid the formation of condensed water from the discharged steam of the cooking device.

[0029] In some technical solutions, optionally, an air supplement hole is provided on the box body, and the air supplement hole is communicated with the installation cavity.

[0030] An air supplement hole is opened on the box body, and the air supplement hole is communicated with the installation cavity. When the fan is running, external gas can be supplemented into the installation cavity through the air supplement hole.

[0031] After the steam discharged from the steam flow channel and the external gas supplemented by the air supplement hole are mixed, the mixed gas is discharged through the steam outlet. The purpose of setting the air supplement hole is to increase the air flow rate, reduce the temperature of the discharged steam, and at the same time can reduce the negative pressure at the steam outlet, avoid the too fast discharge speed of the steam in the steam flow channel, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0032] In some technical solutions, optionally, the opening area of the air supplement hole is greater than or equal to the opening area of the steam outlet.

[0033] When the fan is running, the opening area of the air supplement hole will affect the negative pressure near the steam outlet. When the opening area of the air supplement hole is greater than or equal to the opening area of the steam outlet, the air supplement hole can provide sufficient external air for the fan, effectively reduce the negative pressure at the steam outlet, avoid the too fast discharge speed of the steam in the steam flow channel, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0034] In some technical solutions, optionally, the wind speed V at the air outlet of the fan satisfies V≥1m / s.

[0035] In order to allow the steam in the steam flow channel to be discharged at a high speed into the room-temperature atmosphere, 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 are quickly mixed with the air, making it 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 aggregating somewhere, thus avoiding the formation of condensed water. In order to achieve the above effects, the wind speed at the air outlet of the fan is not less than 1m / s to meet the high-speed drive of the steam.

[0036] In some technical solutions, optionally, the opening area S of the steam outlet satisfies S≥50mm2 .

[0037] The opening area of the steam outlet is greater than or equal to 50 mm 2 , ensuring that the steam can be discharged smoothly and preventing steam from accumulating in the steam material.

[0038] In some technical solutions, optionally, the base assembly further includes: a filter screen, connected to the flow guide member, and the filter screen is located in the steam flow channel.

[0039] Steam can pass through the filter screen, but the filter screen can reduce the flow rate of steam in the steam flow channel, thereby extending the flow duration of steam in the steam flow channel, and further increasing the heat exchange duration between steam and water.

[0040] In a second aspect, the present utility model provides a cooking device, including the base assembly as in the first aspect.

[0041] In some technical solutions, optionally, the cooking device further includes: a steamer assembly, disposed on the base assembly.

[0042] In some technical solutions, optionally, the steamer assembly includes: a steamer, disposed on the base assembly; a lid, covering the steamer to form a closed space between the lid and the steamer.

[0043] Food ingredients can be placed in the steamer, and the space between the lid and the steamer is the cooking cavity. When the lid covers the steamer, the space between the lid and the steamer is in a closed state, that is, there are no air holes for exhaust on the lid, so that the gas in the cooking cavity will not be discharged outward through the lid, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged outward.

Detailed implementation manners

[0057] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0058] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0059] Next, refer to Figures 1 to 9 Describe the base assembly and cooking device provided according to some embodiments of the present utility model.

[0060] Combined with Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, in an embodiment of the present utility model, a base assembly 100 is proposed. The base assembly 100 is for a cooking device, and the cooking device has a cooking cavity 210. The base assembly 100 includes: a box body 110 and a flow guiding member 130. The box body 110 has a steam inlet 111, a steam outlet 112, and a liquid storage cavity 113. The steam inlet 111 is also used to communicate with the cooking cavity 210. The flow guiding member 130 is connected to the box body 110 and is located in the liquid storage cavity 113. The flow guiding member 130 is provided with a steam flow channel 114, and both the steam inlet 111 and the steam outlet 112 are communicated with the steam flow channel 114. A maximum liquid level line 115 is provided on the liquid storage cavity 113. Taking the bottom wall of the liquid storage cavity 113 as the reference plane, both the steam inlet 111 and the steam outlet 112 are higher than the maximum liquid level line 115.

[0061] For the base assembly 100 provided in this embodiment, a steam inlet 111 is provided on the box body 110, and the steam inlet 111 is used to communicate with the cooking cavity 210. Therefore, the steam in the cooking cavity 210 can flow into the box body 110 through the steam inlet 111. A steam flow channel 114 is provided on the flow guiding member 130, and one end of the steam flow channel 114 is communicated with the steam inlet 111. The steam in the cooking cavity 210 can flow into the steam flow channel 114 from one end of the steam flow channel 114. Since the steam flow channel 114 is communicated with the liquid storage cavity 113 and there is water in the liquid storage cavity 113, the steam flowing into the steam flow channel 114 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam flow channel 114 is also communicated with the steam outlet 112. The steam in the steam flow channel 114 that has been cooled by heat exchange can be discharged from the box body 110. Since the temperature of the steam discharged from the box body 110 is relatively low, users around the cooking device are not easily scalded by the steam, which is beneficial to improving the safety of users during the cooking process.

[0062] Figure 2 The arrow inside the cooking device in the figure is used to indicate the steam flow direction.

[0063] When a user fills water into the liquid storage cavity 113, the liquid level usually will not be higher than the maximum liquid level line 115. Both the steam inlet 111 and the steam outlet 112 are higher than the maximum liquid level line 115, so that the water in the liquid storage cavity 113 will not submerge the steam inlet 111 and the steam outlet 112, ensuring that the steam can stably flow into the steam flow channel 114 and stably flow out of the steam flow channel 114.

[0064] Figure 5 The arrow in the steam flow channel 114 in the figure is used to indicate the steam flow direction.

[0065] In some embodiments, optionally, the steam flow channel 114 is communicated with the liquid storage cavity 113, and the steam flowing into the steam flow channel 114 is used to exchange heat with the water in the liquid storage cavity 113.

[0066] The flow guide member 130 is used to extend into the liquid storage cavity 113, and the steam flowing back into the steam flow channel 114 is used to contact and exchange heat with the water in the liquid storage cavity 113.

[0067] In a possible application, a part of the flow guide member 130 is immersed in the water in the water supply area, so that the water can exchange heat with the flow guide member 130. When steam flows in the steam flow channel 114, the steam can indirectly exchange heat with the water through the flow guide member 130.

[0068] Alternatively, an opening is provided at the bottom of the flow guide member 130, so that the steam flow channel 114 in the flow guide member 130 is in direct contact with the water, thereby enabling the steam to directly exchange heat with the water. A part of the flow guide member 130 is immersed in the water, and the water acts as a barrier to the steam, ensuring that the steam can only flow in the steam flow channel 114 and is not likely to flow out of the steam flow channel 114. That is, it can ensure that the steam can stably exchange heat with the water and also ensure that the steam flow channel 114 can stably guide the steam.

[0069] Combined Figure 2 、 Figure 4 and Figure 7 As shown in

[0070] In some embodiments, optionally, the base assembly 100 further includes: an evaporation hood 140. The evaporation hood 140 is located in the liquid storage cavity 113. A steam generation cavity 141 is provided in the evaporation hood 140. The steam generation cavity 141 is communicated with the liquid storage cavity 113. A steam supply port 116 is provided on the box body 110. The steam generated in the steam generation cavity 141 is discharged into the cooking cavity 210 through the steam supply port 116.

[0071] A steam generation chamber 141 is provided inside the evaporation hood 140. The steam generation chamber 141 is in communication with the steam supply port 116. When the water in the steam generation chamber 141 is heated, steam is generated. The steam in the steam generation chamber 141 is discharged into the cooking chamber 210 through the steam supply port 116. The evaporation hood 140 can define a steam generation chamber 141. There is less water stored in the steam generation chamber 141. Therefore, the small amount of water in the steam generation chamber 141 can be quickly heated into steam, which is beneficial to improving the steam generation speed and further beneficial to improving the heating effect on the food materials.

[0072] The steam generation chamber 141 is in communication with the liquid storage chamber 113, so that the liquid storage chamber 113 can supply water to the steam generation chamber 141 to avoid dry burning problems.

[0073] In a possible application, an opening 142 is provided on the side of the evaporation hood 140. The steam generation chamber 141 and the liquid storage chamber 113 are in communication through the opening 142 on the side. Alternatively, the bottom of the evaporation hood 140 is spaced from the bottom wall of the liquid storage chamber 113, so that the water in the liquid storage chamber 113 enters the steam generation chamber 141 through the bottom of the evaporation hood 140.

[0074] In a possible application, the box body 110 includes a water tank 121 and a juice receiving tray 122. A liquid storage chamber 113 is formed between the juice receiving tray 122 and the water tank 121. The juice receiving tray 122 is provided with a steam inlet 111, a steam outlet 112 and a steam supply port 116. The cooking chamber 210 is located above the juice receiving tray 122. The juice receiving tray 122 is used to receive the juice dripping from the food materials. The juice receiving tray 122 is placed on the water tank 121. The user can pick up the juice receiving tray 122 to pour the juice on the juice receiving tray 122, or clean the inside of the water tank 121.

[0075] In a possible application, the guiding member 130 is connected to the juice receiving tray 122.

[0076] In a possible application, the evaporation hood 140 is placed inside the water tank 121, or the evaporation hood 140 is connected to the inside of the water tank 121.

[0077] In a possible application, the base assembly 100 further includes a heater 124. The heater 124 is provided on the water tank 121. The heater 124 is used to heat the steam generation chamber 141.

[0078] Combined Figure 3 、 Figure 4 and Figure 8 As shown in

[0079] The steam inlet 111 and the steam outlet 112 are arranged on the side of the box body 110, and the steam supply port 116 is arranged at the middle position of the top of the box body 110, so that the steam inlet 111 is far away from the steam supply port 116, preventing the steam discharged from the steam supply port 116 from directly flowing towards the steam inlet 111, ensuring that the steam can fill the cooking cavity 210 and improving the cooking effect on the food ingredients.

[0080] As Figure 5 shown, in some embodiments, optionally, the steam flow channel 114 is distributed along the circumferential direction of the evaporation hood 140 ( Figure 5 the direction indicated by the arrow at C in the figure).

[0081] The steam flow channel 114 is distributed along the circumferential direction of the evaporation hood 140, enabling the steam flow channel 114 to avoid the evaporation hood 140, and the steam flow channel 114 can also be bent along the circumferential direction of the evaporation hood 140, which is beneficial to increasing the length of the steam flow channel 114, prolonging the circulation time of the steam in the steam flow channel 114, and improving the heat exchange effect between the steam and the water.

[0082] In some embodiments, optionally, the bottom of the guide member 130 is spaced from the inner wall of the liquid storage cavity 113, and the bottom of the guide member 130 is higher than the bottom of the evaporation hood 140.

[0083] The bottom of the guide member 130 is not attached to the inner wall of the liquid storage cavity 113, so that water can flow at the bottom of the guide member 130. Since the bottom of the guide member 130 is higher than the bottom of the evaporation hood 140, the guide member 130 does not obstruct the water flowing towards the evaporation hood 140, thus ensuring that the water in the liquid storage cavity 113 can be smoothly replenished into the steam generation cavity 141.

[0084] In some embodiments, optionally, along the extension direction of the steam flow channel 114, the length L of the steam flow channel 114 is greater than or equal to 1000 mm.

[0085] The greater the length of the steam flow channel 114, the longer the flow time of the steam in the steam flow channel 114, thereby increasing the heat exchange time between the steam and the water and improving the heat recovery effect.

[0086] As Figure 5 shown, in some embodiments, optionally, the width W of the steam flow channel 114 satisfies W≥5 mm.

[0087] The greater the width of the steam flow channel 114, the larger the heat exchange area between the steam and the water, which is beneficial to improving the heat recovery efficiency.

[0088] Combined with Figure 2 、 Figure 4 and Figure 5As shown, in some embodiments, optionally, the base assembly 100 further includes: a fan 150, which is connected to the box body 110, and the fan 150 is used to pump the steam in the steam flow channel 114 towards the steam outlet 112.

[0089] When the fan 150 operates, the fan 150 is used to pump the steam in the steam flow channel 114 towards the steam outlet 112. Driven by the fan 150, the steam is discharged to the outside of the cooking device at a relatively high flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is relatively large, and the water molecules in the steam quickly mix with the air, making it 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 aggregating in a certain place, thus avoiding the formation of condensed water.

[0090] The box body 110 further includes a base 123, and the water tank 121 and the fan 150 are arranged on the base 123.

[0091] As Figure 4 shown, the steam outlet 112 is arranged on the base 123, and the steam flow channel 114 is communicated with the steam outlet 112 through a channel inside the base 123.

[0092] As Figure 8 shown, the steam outlet 112 is arranged on the juice collecting tray 122.

[0093] As Figure 2 shown, in some embodiments, optionally, an installation cavity 117 is provided on the box body 110, and the steam flow channel 114 is communicated with the steam outlet 112 through the installation cavity 117, and the fan 150 is located inside the installation cavity 117.

[0094] An installation cavity 117 is provided on the box body 110. The installation cavity 117 is used to install the fan 150, and the installation cavity 117 is used to communicate the steam flow channel 114 and the steam outlet 112. By arranging the fan 150 inside the installation cavity 117, the air flow flowing into the installation cavity 117 basically comes from the steam flow channel 114, and it is not easy for the fan 150 to extract the air inside the box body 110 and outside the steam flow channel 114, so as to ensure that the steam in the steam flow channel 114 is discharged at a relatively high flow rate, and further avoid the formation of condensed water in the steam discharged from the cooking device.

[0095] Combined with Figure 2 、 Figure 4 and Figure 9 shown, in some embodiments, optionally, an air supply hole 118 is provided on the box body 110, and the air supply hole 118 is communicated with the installation cavity 117.

[0096] An air replenishing hole 118 is formed in the box body 110, and the air replenishing hole 118 communicates with the installation cavity 117. When the fan 150 operates, external gas can be supplemented into the installation cavity 117 through the air replenishing hole 118.

[0097] After the steam discharged from the steam flow channel 114 is mixed with the external gas replenished through the air replenishing hole 118, the mixed gas is discharged through the steam outlet 112. The purpose of setting the air replenishing hole 118 is to increase the air flow rate, reduce the temperature of the discharged steam, and at the same time can reduce the negative pressure at the steam outlet 112, avoid the steam in the steam flow channel 114 from being discharged too fast, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0098] In some embodiments, optionally, the opening area of the air replenishing hole 118 is greater than or equal to the opening area of the steam outlet 112.

[0099] When the fan 150 operates, the opening area of the air replenishing hole 118 will affect the negative pressure near the steam outlet 112. When the opening area of the air replenishing hole 118 is greater than or equal to the opening area of the steam outlet 112, the air replenishing hole 118 can provide sufficient external air for the fan 150, effectively reduce the negative pressure at the steam outlet 112, avoid the steam in the steam flow channel 114 from being discharged too fast, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0100] In some embodiments, optionally, the wind speed V at the air outlet of the fan 150 satisfies V≥1m / s.

[0101] In order to allow the steam in the steam flow channel 114 to be discharged at a high speed into the room-temperature atmosphere, 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 condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules accumulating in a certain place, thus avoiding the formation of condensed water. To achieve the above effects, the wind speed at the air outlet of the fan 150 is not less than 1m / s to meet the high-speed drive of the steam.

[0102] In some embodiments, optionally, the opening area S of the steam outlet 112 satisfies S≥50mm 2 。

[0103] The opening area of the steam outlet 112 is greater than or equal to 50mm 2 to ensure that the steam can be discharged smoothly and avoid the steam from accumulating in the steam material.

[0104] In some embodiments, optionally, the base assembly 100 further includes: a filter screen 160, the filter screen 160 is connected to the guide member 130, and the filter screen 160 is located in the steam flow channel 114.

[0105] Steam can pass through the filter screen 160, but the filter screen 160 can reduce the flow rate of the steam in the steam flow channel 114, thereby prolonging the flow duration of the steam in the steam flow channel 114, and further increasing the heat exchange duration between the steam and the water.

[0106] In an embodiment of the present utility model, a cooking device is proposed, which includes the base assembly 100 in any of the above embodiments and can achieve the same technical effects, and will not be elaborated here.

[0107] Combined Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cooking device further includes: a steamer assembly 200, and the steamer assembly 200 is disposed on the base assembly 100.

[0108] The steamer assembly 200 has a cooking cavity 210, and the steam discharged from the steam supply port 116 is directly discharged into the cooking cavity 210.

[0109] In some embodiments, optionally, the steamer assembly 200 includes: a steamer 220 and a lid 230. The steamer 220 is disposed on the base assembly 100, and the lid 230 covers the steamer 220 to form a closed space inside the lid 230 and the steamer 220.

[0110] Food ingredients can be placed in the steamer 220, and the space inside the lid 230 and the steamer 220 is the cooking cavity 210. When the lid 230 covers the steamer 220, the inside of the lid 230 and the steamer 220 is in a closed state, that is, no air holes for exhausting are provided on the lid 230, so that the gas in the cooking cavity 210 will not be discharged outward through the lid 230, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged outward.
