Description

Technical Field

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

[0002] During the cooking process of cooking equipment, a large amount of high-temperature steam will be generated. 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 the problem in the prior art or related art that users are easily scalded by high-temperature steam, resulting in poor safety during the cooking process.

[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 base; a steam generating assembly connected to the base. The steam generating assembly is provided with a steam inlet, a steam outlet, a steam supply port and an inner cavity. A steam flow channel is arranged in the inner cavity. The steam inlet and the steam outlet are communicated through the steam flow channel. In the extending direction of the steam flow channel, at least one bent section is arranged on the steam flow channel. Wherein, the steam generated by the steam generating assembly is used to be discharged into the cooking cavity through the steam supply port. The steam inlet is used for the steam in the cooking cavity to flow back into the steam flow channel. The steam flowing back into the steam flow channel is used to be discharged outwards through the steam outlet.

[0005] The steam generating assembly is arranged on the base. When the steam generating assembly operates, the steam generating assembly heats the water in the inner cavity, so that the steam generating assembly can generate steam. A steam supply port is arranged on the steam generating assembly. The steam generated by the steam generating assembly can be discharged into the cooking cavity through the steam supply port, so as to heat the food materials in the cooking cavity.

[0006] A steam flow channel is arranged in the inner cavity. The steam can heat the food materials in the cooking cavity. As the amount of steam in the cooking cavity gradually increases, the steam in the cooking cavity can flow into the steam flow channel from the steam inlet. Since there is water in the inner 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 outlet is communicated with the outside of the cooking equipment. The steam flows through the steam flow channel and is discharged outwards through the steam outlet. That is, the steam in the steam flow channel whose temperature has been reduced through heat exchange can be discharged from the cooking equipment. Since the temperature of the steam discharged from the cooking equipment 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.

[0007] Moreover, during the heat exchange process between the steam and the water in the inner cavity, the heat of the high-temperature steam is transferred to the water, thus realizing the recovery of the steam heat and avoiding waste of the steam heat. In addition, by heating the water with high-temperature steam, the temperature of the water can be increased, so that the water in the inner cavity can be quickly heated into steam, reducing the heating time of the water by the steam generating component, thereby reducing the energy consumption of the steam generating component and being beneficial to improving the energy utilization rate.

[0008] The steam flows from the steam inlet to the steam outlet. The longer the flow path of the steam in the steam flow channel, the longer the heat exchange time between the steam and the water. Therefore, at least one bent section is formed on the steam flow channel, that is, the steam flow channel does not extend linearly from the steam inlet to the steam outlet, but forms a bent structure between the steam inlet and the steam outlet. Compared with the steam flow channel being a linear structure, forming a bent section on the steam flow channel can extend the length of the steam flow channel, thereby increasing the flow time of the steam in the steam flow channel, increasing the heat exchange time between the steam and the water, effectively reducing the temperature of the steam, and ensuring that the steam discharged from the cooking device is not easy to scald the user.

[0009] In addition, according to the base component in the above technical solution provided by the present utility model, the following additional technical features may also be provided:

[0010] In some technical solutions, optionally, the steam inlet and the steam outlet are distributed diagonally along the steam generating component.

[0011] The steam in the steam flow channel flows from the steam inlet to the steam outlet. Therefore, the setting positions of the steam inlet and the steam outlet will affect the flow time of the steam in the steam flow channel. Setting the steam inlet and the steam outlet at the diagonal positions of the steam generating component makes the steam inlet and the steam outlet far away from each other. Moreover, since a bent section is formed on the steam flow channel, the steam can flow in the steam flow channel for a longer time, which is beneficial to improving the steam cooling effect.

[0012] In some technical solutions, optionally, the inner cavity is used for storing water, the steam flow channel is communicated with the inner cavity, and the steam flowing back into the steam flow channel is used to contact and exchange heat with the water in the inner cavity.

[0013] In this solution, it is defined that the steam flow channel is communicated with the inner cavity, that is, an opening is provided at the bottom of the steam flow channel, and the steam flow channel is communicated with the inner cavity through the opening. After the steam flows into the steam flow channel, the steam in the steam flow channel exchanges heat with the water in the inner cavity. Since the steam flow channel is communicated with the inner cavity, the steam can directly contact the water, enabling the steam to directly exchange heat with the water, which is beneficial to improving the heat exchange efficiency of the steam and ensuring that the steam discharged from the cooking device has a lower temperature.

[0014] In some technical solutions, optionally, the steam supply port and the steam flow channel are independent of each other.

[0015] The steam generated by the steam generating assembly is discharged into the cooking cavity through the steam supply port. When the steam supply port and the steam flow channel are set to be independent of each other, the steam flowing back into the steam flow channel is not likely to be discharged into the cooking cavity again through the steam supply port, thereby avoiding the mixing of the steam discharged into the cooking cavity and the steam flowing back into the steam flow channel, and ensuring the independence of the steam for heating and the steam for discharging outward.

[0016] In some technical solutions, optionally, the base assembly further includes: a diversion pipe, which is connected to the steam generating assembly and is located in the inner cavity. The first end of the diversion pipe is communicated with the steam inlet, and the second end of the diversion pipe extends towards the bottom of the inner cavity.

[0017] A diversion pipe is provided on the steam generating assembly, and the diversion pipe guides the steam. The diversion pipe extends from the steam inlet towards the bottom of the inner cavity, so that the diversion pipe extends towards the liquid level in the inner cavity. Under the guiding action of the diversion pipe, the steam directly flows towards the liquid level, ensuring that the steam quickly contacts the liquid level and improving the heat exchange efficiency of the steam.

[0018] In some technical solutions, optionally, the opening area of the steam outlet is greater than or equal to the opening area of the steam inlet.

[0019] The opening area of the steam outlet is relatively large, and the opening area of the steam inlet is relatively small, which can ensure that the steam can flow smoothly in the steam flow channel and the steam is not likely to accumulate in the steam flow channel, thereby ensuring the heat exchange effect between the steam and the water.

[0020] In some technical solutions, optionally, a highest liquid level line is provided on the inner cavity. Based on the bottom wall of the inner cavity, a part of the steam flow channel is higher than the highest liquid level line.

[0021] A part of the steam flow channel is higher than the highest liquid level line. Even if the liquid level in the inner cavity has reached the highest liquid level line, a part of the space in the steam flow channel is still higher than the liquid level in the inner cavity, and the space in the steam flow channel above the liquid level is for the steam to flow.

[0022] When the user fills water into the inner cavity, the water in the inner cavity usually does not exceed the highest liquid level line, and a part of the steam flow channel is higher than the highest liquid level line. Therefore, it can be ensured that a part of the space in the steam flow channel is not filled with water, thereby providing space for the flow of steam and ensuring that the steam can flow and exchange heat in the steam flow channel.

[0023] In some technical solutions, optionally, a lowest liquid level line is provided on the inner cavity. Based on the bottom wall of the inner cavity, a part of the steam flow channel is lower than the lowest liquid level line.

[0024] A minimum liquid level line is provided on the inner cavity. The minimum liquid level line serves as a reminder to the user. When the liquid level of the water in the inner cavity approaches the minimum liquid level line, the user needs to inject water into the inner cavity to avoid the problem of dry burning of the steam generating component.

[0025] A part of the steam flow channel is below the minimum liquid level line. Even when the liquid level in the inner cavity is approaching the minimum liquid level line, a part of the water in the inner cavity is still higher than the bottom of the steam flow channel. The water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow channel and is not likely to flow out of the steam flow channel. This can ensure that the steam can conduct stable heat exchange with the water, and also ensure that the steam flow channel can stably guide the steam, improving the heat exchange effect of the steam and ensuring that the steam can be stably discharged from the cooking device to avoid the accumulation of some recycled steam in the steam generating component.

[0026] In some technical solutions, optionally, the steam generating component includes: a guiding member provided with a steam flow channel, and a part of the guiding member is immersed in the water in the inner cavity.

[0027] The guiding member is provided with a steam flow channel, and the guiding member is used to guide the recycled steam so that the steam can flow along the guiding member. Under the guiding action of the guiding member, the steam exchanges heat with the water along a set route, and the steam after heat exchange can flow to the outside of the cooking device.

[0028] A part of the guiding member is immersed in the water, so that the water can exchange heat with the guiding member. In the case of steam flowing inside the guiding member, the steam can indirectly exchange heat with the water through the guiding member.

[0029] Alternatively, an opening is provided at the bottom of the guiding member, so that the steam flow channel inside the guiding member is in direct contact with the water, thereby enabling the steam to directly exchange heat with the water. A part of the guiding member is immersed in the water, and the water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow channel and is not likely to flow out of the steam flow channel. This can ensure that the steam can conduct stable heat exchange with the water, and also ensure that the steam flow channel can stably guide the steam.

[0030] In some technical solutions, optionally, the steam generating component further includes: a water tank; a juice receiving tray provided on the water tank, the inner cavity is located between the juice receiving tray and the water tank, a steam inlet and a steam supply port are provided on the juice receiving tray, and the cooking cavity is located above the juice receiving tray.

[0031] The water tank is used to store water. The juice receiving tray is arranged at the opening position of the water tank, and an inner cavity is formed between the juice receiving tray and the water tank. When the steam generating component is operating, the water in the water tank is heated. After steam is generated in the water tank, the steam is discharged into the cooking cavity through the steam supply port on the juice receiving tray. Since the cooking cavity is located above the juice receiving tray, the steam discharged from the steam supply port directly enters the cooking cavity, thereby ensuring that the high-temperature steam can quickly heat the food ingredients.

[0032] The cooking cavity is located above the juice receiving tray. During the cooking process, the juice receiving tray is used to receive and collect the juice flowing from the food, which is convenient for users to centrally process the juice flowing from the food, and is conducive to improving the user's convenience in using the cooking device. After using the juice receiving tray as the enclosure component of the inner cavity, there is no need to set up additional components that cooperate with the water tank, which is conducive to simplifying the structure of the cooking device.

[0033] In some technical solutions, optionally, a steam outlet is provided on the side of the juice receiving tray, the steam outlet is connected to the steam flow channel, and the steam flowing back into the steam flow channel is discharged outwardly through the steam outlet.

[0034] The steam outlet is arranged on the side of the juice receiving tray, so the steam in the steam flow channel can be directly discharged outward from the steam outlet on the juice receiving tray. The steam inlet and the steam outlet are both arranged on the juice receiving tray, so there is no need to arrange an outlet for steam discharge on the water tank, which can reduce the difficulty of processing the water tank.

[0035] In a possible application, the opening of the steam outlet is opened upward, and when the steam is discharged from the steam outlet, the steam is not easy to rush to the user located at the side of the cooking device, thereby avoiding direct contact between the steam and the user, thereby reducing the chance of the user being scalded.

[0036] In some technical solutions, optionally, the steam generating assembly is located in the base, and an air outlet is provided on the base, and the steam outlet is connected to the air outlet. The base assembly also includes: a fan connected to the base, and the fan is used to pump the steam in the steam flow channel to the air outlet.

[0037] When the fan is running, it is used to pump the steam in the steam flow channel to the outlet. Driven by the fan, the steam is discharged to the outside of the cooking equipment at a high flow rate. Due to the rapid flow and diffusion of 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 steam also reduces the possibility of water molecules gathering in a certain place, thereby avoiding the formation of condensed water.

[0038] An installation cavity is set on the base, and the installation cavity is used for installing a fan. The installation cavity is used to connect the steam outlet and the air outlet. By arranging the fan in the installation cavity, the air flow flowing into the installation cavity basically comes from the steam outlet, and the fan is not easy to draw out the air inside the base, thereby ensuring that the steam in the steam flow channel is discharged at a higher flow rate, further avoiding the formation of condensed water by the steam discharged from the cooking equipment.

[0039] In some technical solutions, optionally, the steam generating assembly further includes: a partition located in the inner cavity, the partition being used to separate the steam supply port and the steam flow channel.

[0040] A partition is provided in the inner cavity. The partition can separate the steam supply port and the steam flow channel, making it difficult for the steam flowing towards the steam supply port and the steam in the steam flow channel to mix with each other. Therefore, the steam generated from the heated water is not likely to flow into the steam flow channel, and the steam flowing back into the steam flow channel 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 channel are two parts of steam that are nearly independent of each other, thereby ensuring that the steam discharged into the cooking cavity has a relatively high temperature and ensuring the heating effect on the food ingredients.

[0041] In some technical solutions, optionally, a steam generation cavity and a water inlet hole are provided on the partition. The steam generation cavity is communicated with the steam supply port, and the inner cavity and the steam generation cavity are communicated through the water inlet hole.

[0042] A steam generation cavity is provided inside the partition. The steam generation cavity is communicated with the steam supply port. The water in the steam generation cavity is heated to generate steam, and the steam in the steam generation cavity is discharged into the cooking cavity through the steam supply port. The partition 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.

[0043] A water inlet hole is provided on the partition. The water inlet hole is used to communicate the steam generation cavity and the inner cavity, and the water in the inner cavity can be injected into the steam generation cavity through the water inlet hole. When the water in the steam generation cavity is heated into steam, the water in the inner cavity is replenished into the steam generation cavity through the water inlet hole to prevent the water in the steam generation cavity from being burned dry. According to the principle of the communicating vessel, the liquid level height in the steam generation cavity is basically the same as the liquid level height in the inner cavity, thus ensuring that a small amount of water is maintained in the steam generation cavity.

[0044] In some technical solutions, optionally, the steam generation assembly further includes: an inner cylinder, located in the steam generation cavity, the top of the inner cylinder is connected to the partition, and the side of the inner cylinder is spaced from the side of the partition.

[0045] The inner cylinder is arranged in the steam generation cavity and is connected to the partition. The inner cylinder will occupy a part of the space in the steam generation cavity, thereby reducing the water storage space in the steam generation cavity. When the amount of water stored in the steam generation cavity is small, the speed of generating steam when the water in the steam generation cavity is heated is faster, which can further improve the steam generation speed. When using the cooking device, the cooking cavity can be filled with steam in a short time, which is beneficial to improving the cooking speed of the food ingredients.

[0046] The top of the inner cylinder is connected to the partition member, making it difficult for the inner cylinder to sway relative to the partition member. During the process of generating steam in the steam generation cavity, the inner cylinder is not likely to collide with the partition member under the action of steam, thus avoiding the generation of noise during cooking. There is a gap between the side of the inner cylinder and the side of the partition member, and this part of the gap is used to store water, so that steam can be quickly generated in this part of the gap.

[0047] In some technical solutions, optionally, the bottom of the inner cylinder is spaced from the bottom wall of the steam generation cavity, and a conduction port is provided at the bottom of the inner cylinder, and the conduction port is communicated with the steam generation cavity.

[0048] A conduction port is provided at the bottom of the inner cylinder, and the inside of the inner cylinder is communicated with the steam generation cavity through the conduction port. Therefore, a part of the water in the steam generation cavity can flow into the inside of the inner cylinder through the conduction port.

[0049] During the process of placing the inner cylinder and the partition member into the inner cavity, the inner cylinder will be affected by the buoyancy of water, resulting in the inner cylinder floating under the action of buoyancy, so that the inner cylinder and the partition member cannot be stably placed at the bottom of the inner cavity. By providing a conduction port at the bottom of the inner cylinder, the water in the steam generation cavity can flow into the inside of the inner cylinder through the conduction port, reducing the buoyancy effect of the water on the inner cylinder, so that it is convenient to place the inner cylinder and the partition member at the bottom of the inner cavity.

[0050] In a second aspect, the present invention provides a cooking device, including the base assembly as in the first aspect.

[0051] In some technical solutions, optionally, the cooking device further includes: a steamer assembly disposed on the base assembly, the steamer assembly having a cooking cavity, and a steam supply port and a steam inlet are both communicated with the cooking cavity.

[0052] In some technical solutions, optionally, the steamer assembly includes: a steamer disposed on the base assembly; a cover body covering the steamer to form a closed space inside the cover body and the steamer.

[0053] Food ingredients can be placed in the steamer, and the space inside the cover body and the steamer is the cooking cavity. When the cover body covers the inside of the steamer, the inside of the cover body and the steamer is in a closed state, that is, no air holes for exhausting are provided on the cover body, so that the gas in the cooking cavity will not be discharged outward through the cover body, thus ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged outward.

Detailed implementation manners

[0065] In order to be able to more clearly understand the above objects, features, and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with 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.

[0066] 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.

[0067] Refer to the following Figures 1 to 7 to describe a base assembly and a cooking device provided according to some embodiments of the present utility model.

[0068] In combination with Figure 1 、 Figure 2 and Figure 3 As shown, in an embodiment of the present utility model, a base assembly 10 for a cooking device is proposed. The cooking device has a cooking cavity 510. The base assembly 10 includes: a base 100 and a steam generating assembly 200. The steam generating assembly 200 is connected to the base 100. The steam generating assembly 200 is provided with a steam inlet 210, a steam outlet 220, a steam supply port 230 and an inner cavity 240. A steam flow channel 250 is provided in the inner cavity 240. The steam inlet 210 and the steam outlet 220 are connected through the steam flow channel 250. In the extending direction of the steam flow channel 250, at least one bent section 251 is provided on the steam flow channel 250. The steam generated by the steam generating assembly 200 is used to be discharged into the cooking cavity 510 through the steam supply port 230. The steam inlet 210 is used for the steam in the cooking cavity 510 to flow back into the steam flow channel 250. The steam flowing back into the steam flow channel 250 is used to be discharged outwards through the steam outlet 220.

[0069] For the cooking device provided by the present utility model, the steam generating assembly 200 is arranged on the base 100. When the steam generating assembly 200 operates, the steam generating assembly 200 heats the water in the inner cavity 240, so that the steam generating assembly 200 can generate steam. A steam supply port 230 is provided on the steam generating assembly 200. The steam generated by the steam generating assembly 200 can be discharged into the cooking cavity 510 through the steam supply port 230, so as to heat the food materials in the cooking cavity 510.

[0070] A steam flow channel 250 is provided in the inner cavity 240. The steam can heat the food materials in the cooking cavity 510. As the amount of steam in the cooking cavity 510 gradually increases, the steam in the cooking cavity 510 can flow into the steam flow channel 250 from the steam inlet 210. Since there is water in the inner cavity 240, the steam flowing into the steam flow channel 250 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam outlet 220 is communicated with the outside of the cooking device. The steam flows through the steam flow channel 250 and is discharged outwards through the steam outlet 220. That is, the steam in the steam flow channel 250 whose temperature is reduced by heat exchange can be discharged from the cooking device. Since the temperature of the steam discharged from the cooking device is relatively low, the users around the cooking device are not easily scalded by the steam, which is beneficial to improving the safety of the users during the cooking process.

[0071] Moreover, during the heat exchange process between the steam and the water in the inner cavity 240, the heat of the high-temperature steam is transferred to the water, thereby realizing the recovery of the steam heat and avoiding waste of the steam heat. In addition, by heating the water with high-temperature steam, the temperature of the water can be increased, so that the water in the inner cavity 240 can be quickly heated into steam, reducing the heating time of the water by the steam generating assembly 200, thereby reducing the energy consumption of the steam generating assembly 200 and being beneficial to improving the energy utilization rate.

[0072] The steam flows from the steam inlet 210 to the steam outlet 220. The longer the flow path of the steam in the steam flow channel 250, the longer the heat exchange time between the steam and the water. Therefore, at least one bent section 251 is formed on the steam flow channel 250, that is, the steam flow channel 250 does not extend linearly from the steam inlet 210 to the steam outlet 220, but forms a bent structure between the steam inlet 210 and the steam outlet 220. Compared with the steam flow channel 250 being a linear structure, forming the bent section 251 on the steam flow channel 250 can extend the length of the steam flow channel 250, thereby increasing the flow time of the steam in the steam flow channel 250, increasing the heat exchange time between the steam and the water, effectively reducing the temperature of the steam, and ensuring that the steam discharged from the cooking device is not likely to scald the user.

[0073] Combined Figure 3 and Figure 4 As shown in, in some embodiments, optionally, the steam inlet 210 and the steam outlet 220 are distributed diagonally along the steam generating assembly 200.

[0074] The steam in the steam flow channel 250 flows from the steam inlet 210 to the steam outlet 220. Therefore, the installation positions of the steam inlet 210 and the steam outlet 220 will affect the flow time of the steam in the steam flow channel 250. By setting the steam inlet 210 and the steam outlet 220 at the diagonal positions of the steam generating assembly 200, the steam inlet 210 and the steam outlet 220 are far away from each other. Moreover, since a bent section 251 is formed on the steam flow channel 250, the steam can flow in the steam flow channel 250 for a longer time, which is beneficial to improving the steam cooling effect.

[0075] Combined Figure 2 and Figure 4 As shown in, in some embodiments, optionally, the inner cavity 240 is used for storing water, the steam flow channel 250 is communicated with the inner cavity 240, and the steam flowing back into the steam flow channel 250 is used for contacting and exchanging heat with the water in the inner cavity 240.

[0076] In this solution, it is defined that the steam flow channel 250 is connected to the inner cavity 240, that is, the steam flow channel 250 is provided with an opening, and the steam flow channel 250 is connected to the inner cavity 240 through the opening. After the steam flows into the steam flow channel 250, the steam in the steam flow channel 250 exchanges heat with the water in the inner cavity 240. Since the steam flow channel 250 is connected to the inner cavity 240, the steam can directly contact the water, enabling the steam to directly exchange heat with the water, which is beneficial to improving the heat exchange efficiency of the steam and ensuring that the steam discharged from the cooking device has a relatively low temperature.

[0077] Combined with Figure 2 and Figure 6 As shown, in some embodiments, optionally, the steam supply port 230 and the steam flow channel 250 are independent of each other.

[0078] The steam generated by the steam generating assembly 200 is discharged to the cooking cavity 510 through the steam supply port 230. The steam in the cooking cavity 510 can flow to the steam flow channel 250. When the steam supply port 230 and the steam flow channel 250 are set to be independent of each other, the steam flowing back into the steam flow channel 250 is not likely to be discharged into the cooking cavity 510 again through the steam supply port 230, thereby avoiding the mixing of the steam discharged into the cooking cavity 510 and the steam flowing back into the steam flow channel 250 and ensuring the independence of the steam for heating and the steam for outward discharge.

[0079] As Figure 4 shown, in some embodiments, optionally, the base assembly 10 further includes: a diversion pipe 800, the diversion pipe 800 is connected to the steam generating assembly 200, the diversion pipe 800 is located in the inner cavity 240, the first end of the diversion pipe 800 is connected to the steam inlet 210, and the second end of the diversion pipe 800 extends towards the bottom of the inner cavity 240.

[0080] The diversion pipe 800 is provided on the steam generating assembly 200, and the diversion pipe 800 plays a role in guiding the steam. The diversion pipe 800 extends from the steam inlet 210 towards the bottom of the inner cavity 240, so that the diversion pipe 800 extends towards the liquid level in the inner cavity 240. Under the guiding action of the diversion pipe 800, the steam directly flows towards the liquid level, ensuring that the steam quickly contacts the liquid level and improving the heat exchange efficiency of the steam.

[0081] In some embodiments, optionally, the opening area of the steam outlet 220 is greater than or equal to the opening area of the steam inlet 210.

[0082] The opening area of the steam outlet 220 is relatively large, and the opening area of the steam inlet 210 is relatively small, which can ensure that the steam can flow smoothly in the steam flow channel 250, and the steam is not likely to accumulate in the steam flow channel 250, thereby ensuring the heat exchange effect between the steam and the water.

[0083] As Figure 5 shown, in some embodiments, optionally, a highest liquid level line 241 is provided on the inner cavity 240. With the bottom wall of the inner cavity 240 as a reference, a part of the steam flow channel 250 is higher than the highest liquid level line 241.

[0084] A part of the steam flow channel 250 is higher than the highest liquid level line 241. Even when the liquid level in the inner cavity 240 has reached the highest liquid level line 241, a part of the space in the steam flow channel 250 is still higher than the liquid level in the inner cavity 240, and the space in the steam flow channel 250 that is higher than the liquid level is for steam to flow.

[0085] When the user fills water into the inner cavity 240, the water in the inner cavity 240 usually does not exceed the highest liquid level line 241, and a part of the steam flow channel 250 is higher than the highest liquid level line 241. Therefore, it can be ensured that a part of the space in the steam flow channel 250 is not filled with water, thereby providing space for the flow of steam and ensuring that steam can flow and exchange heat in the steam flow channel 250.

[0086] As Figure 5 shown, in some embodiments, optionally, a lowest liquid level line 242 is provided on the inner cavity 240. With the bottom wall of the inner cavity 240 as a reference, a part of the steam flow channel 250 is lower than the lowest liquid level line 242.

[0087] The lowest liquid level line 242 is provided on the inner cavity 240, and the lowest liquid level line 242 serves as a reminder to the user. When the liquid level of the water in the inner cavity 240 is approaching the lowest liquid level line 242, the user needs to fill water into the inner cavity 240 to avoid the problem of dry burning of the steam generating assembly 200.

[0088] A part of the steam flow channel 250 is lower than the lowest liquid level line 242. Even when the liquid level in the inner cavity 240 is approaching the lowest liquid level line 242, a part of the water in the inner cavity 240 is still higher than the bottommost part of the steam flow channel 250. The water acts as a barrier to the steam, ensuring that the steam can only flow in the steam flow channel 250, and the steam is not likely to flow out of the steam flow channel 250. That is, it can ensure that the steam can stably exchange heat with the water, and it can also ensure that the steam flow channel 250 can stably guide the steam, improve the heat exchange effect of the steam, ensure that the steam can be stably discharged from the cooking device, and avoid the accumulation of some recycled steam in the steam generating assembly 200.

[0089] Combined with Figure 2 and Figure 4 shown, in some embodiments, optionally, the steam generating assembly 200 includes: a flow guiding member 300. The flow guiding member 300 is provided with a steam flow channel 250, and a part of the flow guiding member 300 is immersed in the water in the inner cavity 240.

[0090] The guide member 300 is provided with a steam flow channel 250, and the guide member 300 is used to guide the recovered steam so that the steam can flow along the guide member 300. Under the guiding effect of the guide member 300, the steam exchanges heat with the water along a set route, and the steam after heat exchange can flow to the outside of the cooking device.

[0091] A portion of the flow guide 300 is submerged in water, so that the water can exchange heat with the flow guide 300 . In the case where steam flows within the steam, the steam can indirectly exchange heat with the water through the flow guide 300 .

[0092] Alternatively, an opening is provided at the bottom of the flow guide 300 so that the steam flow channel 250 in the flow guide 300 is in direct contact with water, thereby enabling direct heat exchange between steam and water. A portion of the flow guide 300 is submerged in water, which blocks the steam, ensuring that the steam can only flow in the steam flow channel 250 and that the steam is not easy to flow out of the steam flow channel 250, thereby ensuring that the steam can stably exchange heat with the water and that the steam flow channel 250 can stably guide the steam.

[0093] Combination Figure 2 and Figure 5 As shown, in some embodiments, optionally, the steam generating assembly 200 further includes: a water tank 260 and a juice receiving tray 270, the juice receiving tray 270 is disposed on the water tank 260, the inner cavity 240 is located between the juice receiving tray 270 and the water tank 260, the steam inlet 210 and the steam supply port 230 are disposed on the juice receiving tray 270, and the cooking cavity 510 is located above the juice receiving tray 270.

[0094] The water tank 260 is used to store water, and the juice receiving tray 270 is set at the opening position of the water tank 260. An inner cavity 240 is formed between the juice receiving tray 270 and the water tank 260. When the steam generating assembly 200 is running, the water in the water tank 260 is heated. After steam is generated in the water tank 260, the steam is discharged into the cooking cavity 510 through the steam supply port 230 on the juice receiving tray 270. Since the cooking cavity 510 is located above the juice receiving tray 270, the steam discharged from the steam supply port 230 directly enters the cooking cavity 510, thereby ensuring that the high-temperature steam can quickly heat the food.

[0095] The cooking cavity 510 is located above the juice receiving tray 270. During the cooking process, the juice receiving tray 270 is used to receive and collect the juice flowing from the food, which is convenient for the user to centrally process the juice flowing from the food, and is conducive to improving the user's convenience in using the cooking device. After using the juice receiving tray 270 as the enclosing component of the inner cavity 240, there is no need to set up additional components that cooperate with the water tank 260, which is conducive to simplifying the structure of the cooking device.

[0096] The juice receiving tray 270 is detachably disposed on the water tank 260, so that the user can pour the juice on the juice receiving tray 270.

[0097] In a possible application, the diversion member 300 is connected to the juice receiving tray 270.

[0098] As Figure 4 shown, in some embodiments, optionally, a steam outlet 220 is provided on the side of the juice receiving tray 270, and the steam outlet 220 is in communication with the steam flow channel 250. The steam flowing back into the steam flow channel 250 is discharged outward through the steam outlet 220.

[0099] The steam outlet 220 is provided on the side of the juice receiving tray 270. Therefore, the steam in the steam flow channel 250 can be directly discharged outward through the steam outlet 220 on the juice receiving tray 270. Both the steam inlet 210 and the steam outlet 220 are provided on the juice receiving tray 270. Therefore, there is no need to provide an outlet for steam discharge on the water tank 260, which can reduce the processing difficulty of the water tank 260.

[0100] In a possible application, the opening of the steam outlet 220 is arranged upward. When the steam is discharged from the steam outlet 220, the steam is not likely to rush towards the user on the side of the cooking device, avoiding direct contact between the steam and the user, thereby reducing the probability of the user being scalded.

[0101] Combined Figure 2 and Figure 5 shown, in some embodiments, optionally, the steam generating assembly 200 is located in the base 100, and an air outlet 110 is provided on the base 100. The steam outlet 220 is in communication with the air outlet 110. The base assembly 10 further includes: a fan 400, the fan 400 is connected to the base 100, and the fan 400 is used to pump the steam in the steam flow channel 250 towards the air outlet 110.

[0102] When the fan 400 operates, the fan 400 is used to pump the steam in the steam flow channel 250 towards the air outlet 110. Driven by the fan 400, 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 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, thereby avoiding the formation of condensed water.

[0103] An installation cavity 120 is provided on the base 100. The fan 400 is installed in the installation cavity 120. The installation cavity 120 is used to connect the steam outlet 220 and the air outlet 110. By arranging the fan 400 in the installation cavity 120, the air flow flowing into the installation cavity 120 basically comes from the steam outlet 220. It is not easy for the fan 400 to extract the air inside the base 100, so as to ensure that the steam in the steam flow channel 250 is discharged at a higher flow rate, and further avoid the formation of condensed water of the steam discharged from the cooking device.

[0104] As Figure 2 shown, in some embodiments, optionally, the steam generating assembly 200 further includes: a partition member 280. The partition member 280 is located in the inner cavity 240, and the partition member 280 is used to separate the steam supply port 230 and the steam flow channel 250.

[0105] A partition member 280 is provided in the inner cavity 240. The partition member 280 can separate the steam supply port 230 and the steam flow channel 250, so that the steam flowing to the steam supply port 230 and the steam in the steam flow channel 250 are not easily mixed with each other. Therefore, the steam generated by the heated water is not easily directed to the steam flow channel 250, and the steam flowing back into the steam flow channel 250 is not easily discharged into the cooking cavity 510 again. It is ensured that the steam flowing into the cooking cavity 510 and the steam flowing back into the steam flow channel 250 are two parts of steam that are approximately independent of each other, so as to ensure that the steam discharged into the cooking cavity 510 has a relatively high temperature and ensure the heating effect on the food ingredients.

[0106] In this embodiment, the partition member 280 is directly placed inside the water tank 260. In other embodiments, the partition member 280 can also be fixed to the juice receiving tray 270.

[0107] Combined with Figure 2 and Figure 7 shown, in some embodiments, optionally, the partition member 280 is provided with a steam generating cavity 281 and a water inlet hole 282. The steam generating cavity 281 is communicated with the steam supply port 230, and the inner cavity 240 and the steam generating cavity 281 are communicated through the water inlet hole 282.

[0108] A steam generating cavity 281 is provided in the partition member 280. The steam generating cavity 281 is communicated with the steam supply port 230. The water in the steam generating cavity 281 will generate steam after being heated. The steam in the steam generating cavity 281 is discharged into the cooking cavity 510 through the steam supply port 230. The partition member 280 can define a steam generating cavity 281. The water storage in the steam generating cavity 281 is less. Therefore, the small amount of water in the steam generating cavity 281 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.

[0109] The water inlet hole 282 is provided on the partition member 280. The water inlet hole 282 is used to connect the steam generation cavity 281 and the inner cavity 240. The water in the inner cavity 240 can be injected into the steam generation cavity 281 through the water inlet hole 282. When the water in the steam generation cavity 281 is heated into steam, the water in the inner cavity 240 is replenished into the steam generation cavity 281 through the water inlet hole 282, avoiding the water in the steam generation cavity 281 from being dried up. According to the principle of communicating vessels, the liquid level height in the steam generation cavity 281 and the liquid level height in the inner cavity 240 are basically the same, so as to ensure that a small amount of water is maintained in the steam generation cavity 281.

[0110] The steam generation assembly 200 further includes a heater 700. The heater 700 is used to heat the water in the steam generation cavity 281. In a possible application, the heater 700 is disposed opposite to the steam generation cavity 281 to improve the heating speed of the water in the steam generation cavity 281.

[0111] Combined Figure 2 and Figure 7 As shown, in some embodiments, optionally, the steam generation assembly 200 further includes: an inner cylinder 290. The inner cylinder 290 is located in the steam generation cavity 281. The top of the inner cylinder 290 is connected to the partition member 280, and the side portion of the inner cylinder 290 is spaced from the side portion of the partition member 280.

[0112] The inner cylinder 290 is disposed in the steam generation cavity 281 and is connected to the partition member 280. The inner cylinder 290 will occupy a part of the space in the steam generation cavity 281, thereby reducing the water storage space in the steam generation cavity 281. When there is less water stored in the steam generation cavity 281, the speed of generating steam when the water in the steam generation cavity 281 is heated is faster, which can further improve the steam generation speed. When using the cooking device, the cooking cavity 510 can be filled with steam in a short time, which is beneficial to improving the cooking speed of the food ingredients.

[0113] The top of the inner cylinder 290 is connected to the partition member 280, so that the inner cylinder 290 is not easily shaken relative to the partition member 280. During the process of generating steam in the steam generation cavity 281, the inner cylinder 290 is not easily collided with the partition member 280 under the action of steam, thereby avoiding generating noise during the cooking process. There is a gap between the side portion of the inner cylinder 290 and the side portion of the partition member 280, and this part of the gap is used for storing water, so that steam can be quickly generated in this part of the gap.

[0114] Combined Figure 2 and Figure 7 As shown, in some embodiments, optionally, the bottom of the inner cylinder 290 is spaced from the bottom wall of the steam generation cavity 281, and a conduction port 291 is provided at the bottom of the inner cylinder 290. The conduction port 291 is communicated with the steam generation cavity 281.

[0115] A conduction port 291 is provided at the bottom of the inner cylinder 290. The interior of the inner cylinder 290 is connected and communicated with the steam generation chamber 281 through the conduction port 291. Therefore, a part of the water in the steam generation chamber 281 can flow into the interior of the inner cylinder 290 through the conduction port 291.

[0116] During the process of placing the inner cylinder 290 and the partition member 280 into the inner cavity 240, the inner cylinder 290 will be affected by the buoyancy of water, resulting in the inner cylinder 290 floating upward under the action of buoyancy, thus causing the inner cylinder 290 and the partition member 280 to be unable to be stably placed at the bottom of the inner cavity 240. By providing the conduction port 291 at the bottom of the inner cylinder 290, the water in the steam generation chamber 281 can flow into the interior of the inner cylinder 290 through the conduction port 291, reducing the buoyancy effect of water on the inner cylinder 290, so that it is convenient to place the inner cylinder 290 and the partition member 280 at the bottom of the inner cavity 240.

[0117] In a possible embodiment, the longer the length of the steam flow channel 250 is, the longer the heat exchange time between the steam and the water is. When the length of the steam flow channel 250 is limited to be greater than or equal to 1000 mm, the steam flow channel 250 has a longer length, and the flow time of the steam in the steam flow channel 250 is longer, thereby extending the heat exchange duration between the steam and the water, improving the heat recovery effect, further reducing the temperature of the steam discharged from the cooking device, and ensuring the safety of the user during the use of the cooking device.

[0118] In the embodiment of the present utility model, a cooking device is proposed, which includes the base assembly 10 in any of the above embodiments and can achieve the same technical effects, which will not be elaborated here.

[0119] As Figure 2 shown, in some embodiments, optionally, the cooking device further includes: a steamer assembly 500. The steamer assembly 500 is provided on the base assembly 10. The steamer assembly 500 has a cooking cavity 510, and both the steam supply port 230 and the steam inlet 210 are connected and communicated with the cooking cavity 510.

[0120] The steamer assembly 500 can be placed on the water tank 260 or on the base 100. The steam is discharged into the steamer assembly 500 through the steam supply port 230.

[0121] As Figure 2 shown, the steam generated by the steam generation assembly 200 is discharged into the cooking cavity 510 through the steam supply port 230. However, both the steam supply port 230 and the steam inlet 210 are provided on the juice collecting tray 270. In order to prevent the steam discharged from the steam supply port 230 into the cooking cavity 510 from directly flowing to the steam inlet 210, a steam return pipe 600 is installed on the steam inlet 210.

[0122] One end of the steam return pipe 600 is connected to the steam inlet 210, and the other end of the steam return pipe 600 extends to the top of the cooking cavity 510. After the steam flows into the cooking cavity 510 through the steam supply port 230, the steam rises in the cooking cavity 510. Since the height of the steam return pipe 600 is relatively high, the steam will flow into the steam return pipe 600 only when the steam flows to the top of the cooking cavity 510. Therefore, when a part of the steam flows to the top of the cooking cavity 510, the steam basically fills the cooking cavity 510, so that the temperature of each place in the cooking cavity 510 is relatively high, ensuring the uniform heating effect of the steam on the food.

[0123] By installing the steam reflux pipe 600 on the steam inlet 210, the steam is not likely to flow directly to the steam inlet 210, thereby ensuring that the steam can effectively heat the food.

[0124] In some embodiments, optionally, the steamer assembly 500 includes: a steamer 520 and a cover 530 , the steamer 520 is disposed on the base assembly 10 , and the cover 530 is covered on the steamer 520 , so that a closed space is formed in the cover 530 and the steamer 520 .

[0125] The food can be placed in the steamer 520, and the space between the cover 530 and the steamer 520 is the cooking cavity 510. When the cover 530 is covered in the steamer 520, the cover 530 and the steamer 520 are in a closed state, that is, the cover 530 is not provided with air holes for exhaust, so that the gas in the cooking cavity 510 will not be discharged to the outside through the cover 530, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged to the outside.

[0126] In the present invention, the term "plurality" means two or more than two, unless otherwise clearly defined. The terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0127] In the description of this specification, the description of the terms "one embodiment", "some embodiments", "specific embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0128] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
