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. The high-temperature steam carries a large amount of heat. When the steam is discharged outward, the heat carried by the steam will also be lost, resulting in heat waste. 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 base; a steam generating assembly connected to the base. The steam generating assembly is provided with a steam inlet, a steam supply port, and an inner cavity. A steam flow channel is provided in the inner cavity. The steam inlet is communicated with the steam flow channel. 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; a partition member located in the inner cavity. The partition member is used to separate the steam supply port and the steam flow channel. A steam generating cavity is provided on the partition member. The steam generating cavity is communicated with the inner cavity. The steam supply port is communicated with the steam generating cavity; wherein, the steam flow channel is distributed along the circumferential direction of the partition member.

[0005] In the base assembly provided by the utility model, 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 provided 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 provided 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. During the heat exchange process between the steam and the water in the inner cavity, the heat of the high-temperature steam will be transferred to the water, thus realizing the recovery of the steam heat and avoiding the waste of the steam heat. Moreover, 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 assembly, thereby reducing the energy consumption of the steam generating assembly and being beneficial to improving the energy utilization rate.

[0007] 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 by 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.

[0008] During the flow of steam in the steam channel, the longer the flow time of the steam, the longer the heat exchange time between the steam and the water, resulting in a better heat recovery effect of the water on the steam. Therefore, the heat exchange duration between the steam and the water can be increased by increasing the length of the steam channel.

[0009] When the steam flow channels are distributed circumferentially along the partition, it means that the steam flow channels extend along the circumference of the partition. Therefore, multiple bent structures will be formed on the steam flow channels. The steam flow channels start from the steam inlet and pass through at least one turn during the flow in the steam flow channels. By the above method, the length of the steam channel can be increased, thereby increasing the heat exchange duration between the steam and the water and improving the heat recovery effect.

[0010] In addition, for the cooking device according to the above technical solution provided by the present invention, the following additional technical features may also be included:

[0011] In some technical solutions, optionally, the steam flow channel includes multiple sub-channels, and adjacent sub-channels among the multiple sub-channels are interconnected.

[0012] Adjacent two sub-channels are connected, and the steam can flow through the multiple sub-channels in sequence. From the first end to the second end of the steam channel, the extension directions of adjacent two sub-channels are different. When the steam passes through adjacent two sub-channels, the flow direction of the steam will change. During the flow of the steam in the multiple sub-channels, the flow direction of the steam will change multiple times, thereby increasing the flow length of the steam in the steam channel, further increasing the heat exchange duration between the steam and the water, and improving the heat recovery effect.

[0013] In some technical solutions, optionally, the multiple sub-channels are arranged in sequence along a first direction, and the adjacent two sub-channels are connected end to end in sequence.

[0014] The multiple sub-channels are arranged in sequence along the first direction, that is, the multiple sub-channels are in a side-by-side distribution form. The multiple side-by-side sub-channels can cover most of the space in the inner cavity, so that the steam flows through most of the space in the inner cavity, and the flow time of the steam in the steam channel is longer, improving the heat recovery effect.

[0015] In some technical solutions, optionally, the first direction is the length direction or the width direction of the steam generating assembly.

[0016] Multiple sub-channels can be sequentially distributed along the length direction of the steam generating component, and each sub-channel can extend along the width direction of the steam generating component. Alternatively, multiple sub-channels are sequentially distributed along the width direction of the steam generating component, and each sub-channel can extend along the length direction of the steam generating component.

[0017] In some technical solutions, optionally, one of the multiple sub-channels is set as the middle section channel. The middle section channel includes a first channel and a second channel. The first channel and the second channel are located on both sides of the partition. The first end of the first channel is communicated with the first end of the second channel, and the second end of the first channel is communicated with the second end of the second channel.

[0018] The multiple sub-channels are distributed side by side. One of the sub-channels passes through the partition. The sub-channel passing through the partition is set as the middle section channel. The middle part of the middle section channel is divided into two parts, that is, the first channel and the second channel. The ends of the first channel and the second channel are communicated, and the first channel and the second channel respectively bypass the partition along both sides of the partition. The first channel and the second channel that bypass the partition converge again. In this way, the middle section channel avoids the partition, and the middle section channel can bypass the partition. The middle section channel is arranged near the partition, increasing the number of sub-channels arranged, thereby increasing the heat exchange duration between steam and water.

[0019] In some technical solutions, optionally, the steam flowing back into the steam channel is used to be discharged to the outside through the steam channel.

[0020] Since there is water in the inner cavity, the steam flowing into the steam channel can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam channel is communicated with the outside of the cooking device, that is, the steam whose temperature has been reduced through heat exchange in the steam channel 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 users during the cooking process.

[0021] In some technical solutions, optionally, the inner cavity is used to store water. The steam channel is communicated with the inner cavity, and the steam flowing back into the steam channel is used to contact and exchange heat with the water in the inner cavity.

[0022] In this solution, it is defined that the steam channel is communicated with the inner cavity, that is, an opening is provided at the bottom of the steam channel, and the steam channel is communicated with the inner cavity through the opening. After the steam flows into the steam channel, the steam in the steam channel exchanges heat with the water in the inner cavity. Since the steam 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 relatively low temperature.

[0023] In some technical solutions, optionally, with the bottom wall of the inner cavity as a reference, a highest liquid level line is provided on the inner cavity, and a part of the steam flow channel is higher than the highest liquid level line.

[0024] A part of the steam flow channel is higher than the highest liquid level line. Even when 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 steam to flow.

[0025] 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, thus providing space for the flow of steam and ensuring that steam can flow and exchange heat in the steam flow channel.

[0026] In some technical solutions, optionally, with the bottom wall of the inner cavity as a reference, a lowest liquid level line is provided on the inner cavity, and a part of the steam flow channel is lower than the lowest liquid level line.

[0027] The lowest liquid level line is provided on the inner cavity, which plays a role of reminding the user. When the liquid level of the water in the inner cavity is approaching the lowest liquid level line, the user needs to fill water into the inner cavity to avoid the problem of dry burning of the steam generating component.

[0028] A part of the steam flow channel is lower than the lowest liquid level line. Even when the liquid level in the inner cavity is approaching the lowest 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 plays a blocking role for the steam, ensuring that the steam can only flow in the steam flow channel, and the steam is not easy to flow out of the steam flow channel. That is, it can ensure that the steam can stably exchange heat with the water, and can also ensure that the steam flow channel can stably guide the steam, improve the heat exchange effect of the steam, and ensure that the steam can be stably discharged from the cooking device to avoid the accumulation of some recycled steam in the steam generating component.

[0029] In some technical solutions, optionally, the partition member is provided with a communication hole, and the steam generating cavity and the inner cavity are connected through the communication hole. With the bottom wall of the inner cavity as a reference, a part of the steam flow channel is higher than the lowest end of the communication hole.

[0030] To ensure the flow of steam in the steam flow channel, at least a part of the guiding member needs to be immersed in water, that is, a part of the water will enter the steam flow channel. Since a part of the steam flow channel is higher than the lowest end of the communication hole, it is ensured that a part of the communication hole is immersed in water, ensuring that water can be replenished into the steam generating cavity in time.

[0031] In some technical solutions, optionally, the steam generating component includes: a guiding member, the guiding member is provided with a steam flow channel, and a part of the guiding member is immersed in the water in the inner cavity.

[0032] The guide member is provided with a steam flow channel, and the guide member is used to guide the recovered steam so that the steam can flow along the guide member. Under the guiding effect of the guide 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.

[0033] A portion of the guide member is immersed in water, so that the water can exchange heat with the guide member. In the case where steam flows within the steam member, the steam can indirectly exchange heat with the water through the guide member.

[0034] Alternatively, an opening is provided at the bottom of the flow guide so that the steam flow channel in the flow guide is in direct contact with water, thereby enabling direct heat exchange between steam and water. A portion of the flow guide is submerged in water, which blocks the steam, ensuring that the steam can only flow in the steam flow channel and that the steam is not easy to flow out of the steam flow channel, thereby ensuring that the steam can stably exchange heat with the water and that the steam flow channel can stably guide the steam.

[0035] In some technical solutions, optionally, the steam generating assembly further includes: a water tank; a juice receiving tray, which is disposed on the water tank, and the inner cavity is located between the juice receiving tray and the water tank, and the juice receiving tray is provided with a steam inlet and a steam supply port.

[0036] The water tank is used to store water, and a juice collecting tray is arranged at the opening position of the water tank. An inner cavity is formed between the juice collecting tray and the water tank. When the steam generating assembly is running, 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 collecting tray. Since the cooking cavity is located above the juice collecting 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.

[0037] 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.

[0038] In some technical solutions, optionally, the base assembly further includes: a filter screen, which is located in the steam flow channel, and at least one filter screen is provided in the steam flow channel along the extension direction of the steam flow channel.

[0039] Steam can pass through the filter, but the filter can reduce the flow velocity of steam in the steam flow channel, thereby extending the flow time of steam in the steam flow channel, and then increasing the heat exchange time between steam and water.

[0040] In some technical solutions, optionally, the side part of the juice receiving tray extends out of the base. A steam outlet is provided on a part of the juice receiving tray that extends out of the base, and the steam outlet is communicated with the steam flow channel. The steam flowing back into the steam flow channel is discharged outward through the steam outlet.

[0041] The steam outlet is arranged on the side part of the juice receiving tray. Therefore, the steam in the steam flow channel can be directly discharged outward through the steam outlet on the juice receiving tray. Both the steam inlet and the steam outlet are arranged on the juice receiving tray. Therefore, there is no need to provide an outlet for steam discharge on the water tank, which can reduce the processing difficulty of the water tank.

[0042] In a possible application, the opening of the steam outlet is arranged upward. When the steam is discharged from the steam outlet, 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.

[0043] In some technical solutions, optionally, the steam generating assembly is located inside the base, and an air outlet is provided on the base. The steam flow channel is communicated with the air outlet.

[0044] The steam generating assembly is arranged inside the base, and the base plays a protective role for the steam generating assembly. The steam in the steam flow channel is discharged outward through the air outlet on the base.

[0045] In some technical solutions, optionally, the cooking device further includes: a fan, which is connected to the base, and the fan is used to pump the steam in the steam flow channel towards the air outlet.

[0046] When the fan operates, the fan is used to pump the steam in the steam flow channel towards the air outlet. Driven by the fan, the steam is discharged to the outside of the cooking device at a higher flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is larger, 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 somewhere, thereby avoiding the formation of condensed water.

[0047] An installation cavity is arranged on the base, and the fan is installed in the installation cavity. The installation cavity is used to communicate 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 likely to pump out the air inside the base, thereby ensuring that the steam in the steam flow channel is discharged at a higher flow rate, and further avoiding the formation of condensed water in the steam discharged from the cooking device.

[0048] In a second aspect, the present utility model proposes a cooking device, including the base assembly as in the first aspect.

[0049] 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 both communicating with the cooking cavity.

[0050] 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.

[0051] 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 gas are provided on the cover body, so that the gas in the cooking cavity will not be discharged outward through the cover body, 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

[0064] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention 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.

[0065] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0066] Next, refer to Figures 1 to 8 Describe a base assembly and a cooking device provided according to some embodiments of the present invention.

[0067] Combined with Figure 2 、 Figure 3 and Figure 4As 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 base 110, a steam generating assembly 120, and a separator 130. The steam generating assembly 120 is connected to the base 110. The steam generating assembly 120 is provided with a steam inlet 121, a steam supply port 122, and an inner cavity 123. A steam flow channel 133 is provided in the inner cavity 123. The steam inlet 121 is communicated with the steam flow channel 133. The steam generated by the steam generating assembly 120 is used to be discharged into the cooking cavity 210 through the steam supply port 122. The steam inlet 121 is used for the steam in the cooking cavity 210 to flow back into the steam flow channel 133. The separator 130 is located in the inner cavity 123. The separator 130 is used to separate the steam supply port 122 and the steam flow channel 133. The separator 130 is provided with a steam generating cavity 131. The steam generating cavity 131 is communicated with the inner cavity 123. The steam supply port 122 is communicated with the steam generating cavity 131. Among them, the steam flow channel 133 is distributed along the circumferential direction ( Figure 4 the arrow direction at C in the figure) of the separator 130.

[0068] For the base assembly 100 provided by the present utility model, the steam generating assembly 120 is arranged on the base 110. When the steam generating assembly 120 operates, the steam generating assembly 120 heats the water in the inner cavity 123, so that the steam generating assembly 120 can generate steam. The steam generating assembly 120 is provided with a steam supply port 122. The steam generated by the steam generating assembly 120 can be discharged into the cooking cavity 210 through the steam supply port 122, so that the food materials in the cooking cavity 210 can be heated.

[0069] A steam flow channel 133 is provided in the inner cavity 123. The steam can heat the food materials in the cooking cavity 210. As the amount of steam in the cooking cavity 210 gradually increases, the steam in the cooking cavity 210 can flow into the steam flow channel 133 from the steam inlet 121. Since there is water in the inner cavity 123, the steam flowing into the steam flow channel 133 can directly or indirectly exchange heat with the water. During the heat exchange process between the steam and the water in the inner cavity 123, the heat of the high-temperature steam will be transferred to the water, thus realizing the recovery of the steam heat and avoiding waste of the steam heat. Moreover, by heating the water with high-temperature steam, the temperature of the water can be increased, so that the water in the inner cavity 123 can be quickly heated into steam, reducing the heating time of the water by the steam generating assembly 120, thereby reducing the energy consumption of the steam generating assembly 120 and being beneficial to improving the energy utilization rate.

[0070] A partition member 130 is disposed in the inner cavity 123. The partition member 130 can separate the steam supply port 122 and the steam flow channel 133, making it difficult for the steam flowing towards the steam supply port 122 and the steam in the steam flow channel 133 to mix with each other. Therefore, the steam generated by the heated water is not likely to flow into the steam flow channel 133, and the steam flowing back into the steam flow channel 133 is not likely to be discharged into the cooking cavity 210 again, ensuring that the steam flowing into the cooking cavity 210 and the steam flowing back into the steam flow channel 133 are two parts of steam that are nearly independent of each other.

[0071] During the flow of steam in the steam channel, the longer the flow time of the steam, the longer the heat exchange time between the steam and the water, resulting in a better heat recovery effect of the water on the steam. Therefore, the heat exchange duration between the steam and the water can be increased by increasing the length of the steam channel.

[0072] When the steam flow channels 133 are circumferentially distributed along the partition member 130, it means that the steam flow channels 133 extend along the circumference of the partition member 130. Therefore, multiple bent structures will be formed on the steam flow channels 133. Starting from the steam inlet 121, the steam flow channels 133 pass through at least one turn during the flow process. By the above method, the length of the steam channel can be increased, thereby increasing the heat exchange duration between the steam and the water and improving the heat recovery effect.

[0073] In a possible application, the partition member 130 is directly placed in the inner cavity 123, or the partition member 130 is connected to the cavity wall of the inner cavity 123.

[0074] Figure 2 The arrows in the figure are used to indicate the steam flow direction.

[0075] Combined with Figure 3 and Figure 4 As shown, in some embodiments, optionally, the steam flow channel 133 includes a plurality of sub-flow channels 134, and adjacent sub-flow channels 134 among the plurality of sub-flow channels 134 are interconnected.

[0076] Adjacent two sub-flow channels 134 are connected, and the steam can flow in the plurality of sub-flow channels 134 in sequence. From the first end to the second end of the steam channel, the extending directions of adjacent two sub-flow channels 134 are different. When the steam passes through adjacent two sub-flow channels 134, the flow direction of the steam will change. During the flow of the steam in the plurality of sub-flow channels 134, the flow direction of the steam will change multiple times, thereby increasing the flow length of the steam in the steam channel, further increasing the heat exchange duration between the steam and the water, and improving the heat recovery effect.

[0077] As Figure 4 shown, in some embodiments, optionally, the plurality of sub-flow channels 134 are arranged along a first direction (the first direction can be Figure 4The arrow at X or the arrow at Y) are arranged in sequence, and the head and tail of two adjacent sub-channels 134 are connected in sequence.

[0078] A plurality of sub-channels 134 are arranged in sequence along the first direction, that is, the plurality of sub-channels 134 are in a side-by-side distribution form. The plurality of side-by-side distributed sub-channels 134 can cover most of the space in the inner cavity 123, so that the steam flows through most of the space in the inner cavity 123, and the steam has a longer circulation time in the steam channel, improving the heat recovery effect.

[0079] In some embodiments, optionally, the first direction is the length direction of the steam generating assembly 120 ( Figure 4 the arrow at Y) or the width direction ( Figure 4 the arrow at X).

[0080] The plurality of sub-channels 134 can be sequentially distributed along the length direction of the steam generating assembly 120, and each sub-channel 134 can extend along the width direction of the steam generating assembly 120. Alternatively, the plurality of sub-channels 134 are sequentially distributed along the width direction of the steam generating assembly 120, and each sub-channel 134 can extend along the length direction of the steam generating assembly 120.

[0081] Such as Figure 4 shown, in some embodiments, optionally, one of the plurality of sub-channels 134 is set as the middle section channel 135. The middle section channel 135 includes a first channel 136 and a second channel 137. The first channel 136 and the second channel 137 are located on both sides of the separator 130. The first end of the first channel 136 is connected to the first end of the second channel 137, and the second end of the first channel 136 is connected to the second end of the second channel 137.

[0082] The plurality of sub-channels 134 are distributed side by side. One of the sub-channels 134 will pass through the separator 130. The sub-channel 134 passing through the separator 130 is set as the middle section channel 135. The middle part of the middle section channel 135 is divided into two parts, that is, the first channel 136 and the second channel 137. The ends of the first channel 136 and the second channel 137 are connected, and the first channel 136 and the second channel 137 respectively bypass the separator 130 along both sides of the separator 130. The first channel 136 and the second channel 137 that bypass the separator 130 converge again. In this way, the middle section channel 135 avoids the separator 130, and the middle section channel 135 can bypass the separator 130. The middle section channel 135 is arranged near the separator 130, increasing the number of sub-channels 134 provided, thereby increasing the heat exchange time between the steam and the water.

[0083] In some embodiments, optionally, the steam flowing back into the steam channel 133 is used to be discharged to the outside through the steam channel 133.

[0084] Since there is water in the inner cavity 123, the steam flowing into the steam flow channel 133 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam flow channel 133 is connected to the outside of the cooking device, that is, the steam in the steam flow channel 133 that has been cooled by heat exchange can be discharged from the cooking device. Since the temperature of the steam discharged from the cooking device 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.

[0085] In some embodiments, optionally, the inner cavity 123 is used to store water, the steam flow channel 133 is connected to the inner cavity 123, and the steam flowing back into the steam flow channel 133 is used to contact and exchange heat with the water in the inner cavity 123.

[0086] In this solution, it is defined that the steam flow channel 133 is connected to the inner cavity 123, that is, an opening is provided at the bottom of the steam flow channel 133, and the steam flow channel 133 is connected to the inner cavity 123 through the opening. After the steam flows into the steam flow channel 133, the steam in the steam flow channel 133 exchanges heat with the water in the inner cavity 123. Since the steam flow channel 133 is connected to the inner cavity 123, 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.

[0087] Combined with Figure 2 and Figure 5 As shown, in some embodiments, optionally, with the bottom wall of the inner cavity 123 as a reference, a maximum liquid level line 138 is provided on the inner cavity 123, and a part of the steam flow channel 133 is higher than the maximum liquid level line 138.

[0088] A part of the steam flow channel 133 is higher than the maximum liquid level line 138. Even if the liquid level height in the inner cavity 123 has reached the maximum liquid level line 138, a part of the space in the steam flow channel 133 is still higher than the liquid level in the inner cavity 123, and the space in the steam flow channel 133 above the liquid level is for the steam to flow.

[0089] When the user fills water into the inner cavity 123, the water in the inner cavity 123 usually does not exceed the maximum liquid level line 138, and a part of the steam flow channel 133 is higher than the maximum liquid level line 138. Therefore, it can be ensured that a part of the space in the steam flow channel 133 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 133.

[0090] Combined with Figure 2 and Figure 5 As shown, in some embodiments, optionally, with the bottom wall of the inner cavity 123 as a reference, a minimum liquid level line 139 is provided on the inner cavity 123, and a part of the steam flow channel 133 is lower than the minimum liquid level line 139.

[0091] A lowest liquid level line 139 is provided on the inner cavity 123. The lowest liquid level line 139 serves as a reminder to the user. When the liquid level of the water in the inner cavity 123 approaches the lowest liquid level line 139, the user needs to inject water into the inner cavity 123 to avoid the problem of dry burning of the steam generating assembly 120.

[0092] A part of the steam flow channel 133 is lower than the lowest liquid level line 139. Even when the liquid level height in the inner cavity 123 has approached the lowest liquid level line 139, a part of the water in the inner cavity 123 is still higher than the bottommost part of the steam flow channel 133. The water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow channel 133 and is not likely to flow out of the steam flow channel 133. That is, it can ensure that the steam can conduct stable heat exchange with the water, and can also ensure that the steam flow channel 133 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 within the steam generating assembly 120.

[0093] Combined Figure 2 and Figure 7 As shown, in some embodiments, optionally, the partition member 130 is provided with a communication hole 132. The steam generating cavity 131 and the inner cavity 123 are connected through the communication hole 132. Based on the bottom wall of the inner cavity 123, a part of the steam flow channel 133 is higher than the lowest end of the communication hole 132.

[0094] To ensure the flow of steam within the steam flow channel 133, at least a part of the guiding member 140 needs to be immersed in water, that is, a part of the water will enter the steam flow channel 133. Since a part of the steam flow channel 133 is higher than the lowest end of the communication hole 132, it ensures that a part of the communication hole 132 is immersed in water, guaranteeing that water can be replenished into the steam generating cavity 131 in a timely manner.

[0095] Combined Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, optionally, the steam generating assembly 120 includes: a guiding member 140. The guiding member 140 is provided with a steam flow channel 133, and a part of the guiding member 140 is immersed in the water in the inner cavity 123.

[0096] The guiding member 140 is provided with a steam flow channel 133. The guiding member 140 is used to guide the recycled steam so that the steam can flow along the guiding member 140. Under the guiding action of the guiding member 140, the steam exchanges heat with the water along a set route, and the heat-exchanged steam can flow to the outside of the cooking device.

[0097] A part of the flow guide member 140 is immersed in water, so that the water can exchange heat with the flow guide member 140. In the case of steam flowing in the steam, the steam can indirectly exchange heat with the water through the flow guide member 140.

[0098] Alternatively, an opening is provided at the bottom of the flow guide member 140, so that the steam flow channel 133 in the flow guide member 140 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 140 is immersed in water, and the water acts as a barrier to the steam, ensuring that the steam can only flow in the steam flow channel 133 and is not likely to flow out of the steam flow channel 133. That is, it can ensure that the steam can stably exchange heat with the water and can also ensure that the steam flow channel 133 can stably guide the steam.

[0099] Combined Figure 2 、 Figure 5 and Figure 6 As shown in

[0100] In some embodiments, optionally, the steam generating assembly 120 further includes: a water tank 151 and a juice receiving tray 152. The juice receiving tray 152 is disposed on the water tank 151, and the inner cavity 123 is located between the juice receiving tray 152 and the water tank 151. The juice receiving tray 152 is provided with a steam inlet 121 and a steam supply port 122.

[0101] The water tank 151 is used for storing water. The juice receiving tray 152 is disposed at the opening position of the water tank 151. An inner cavity 123 is formed between the juice receiving tray 152 and the water tank 151. When the steam generating assembly 120 operates, the water in the water tank 151 is heated. After steam is generated in the water tank 151, the steam is discharged into the cooking cavity 210 through the steam supply port 122 on the juice receiving tray 152. Since the cooking cavity 210 is located above the juice receiving tray 152, the steam discharged from the steam supply port 122 directly enters the cooking cavity 210, thereby ensuring that the high-temperature steam can quickly heat the food ingredients.

[0102] The juice receiving tray 152 is detachably disposed on the water tank 151, so that the user can pour the juice on the juice receiving tray 152.

[0103] In a possible application, the top of the flow guide member 140 is connected to the juice receiving tray 152.

[0104] The steam generating assembly 120 further includes: a heater 154 disposed on the water tank 151, and the heater 154 is configured to heat the steam generating chamber 131.

[0105] As Figure 4 shown, in some embodiments, optionally, the base assembly 100 further includes: a filter screen 160 located in the steam flow channel 133, and along the extending direction of the steam flow channel 133, at least one filter screen 160 is provided in the steam flow channel 133.

[0106] 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 133, thereby extending the flow duration of the steam in the steam flow channel 133, and further increasing the heat exchange duration between the steam and water.

[0107] As Figure 8 shown, in some embodiments, optionally, a side portion of the juice receiving tray 152 extends out of the base 110, and a steam outlet 153 is provided on a part of the juice receiving tray 152 that extends out of the base 110. The steam outlet 153 is in communication with the steam flow channel 133, and the steam flowing back into the steam flow channel 133 is discharged outward through the steam outlet 153.

[0108] The steam outlet 153 is provided on the side portion of the juice receiving tray 152. Therefore, the steam in the steam flow channel 133 can be directly discharged outward through the steam outlet 153 on the juice receiving tray 152. Both the steam inlet 121 and the steam outlet 153 are provided on the juice receiving tray 152. Therefore, there is no need to provide an outlet for steam discharge on the water tank 151, which can reduce the processing difficulty of the water tank 151.

[0109] In a possible application, the opening of the steam outlet 153 is arranged upward. When the steam is discharged from the steam outlet 153, 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.

[0110] Combined Figure 2 and Figure 5 shown, in some embodiments, optionally, the steam generating assembly 120 is located in the base 110, and an air outlet 111 is provided on the base 110. The steam flow channel 133 is in communication with the air outlet 111.

[0111] The steam generating assembly 120 is disposed in the base 110, and the base 110 plays a protective role for the steam generating assembly 120. The steam in the steam flow channel 133 is discharged outward through the air outlet 111 on the base 110.

[0112] As Figure 2As shown, in some embodiments, optionally, the cooking device further includes: a blower 170, which is connected to the base 110, and the blower 170 is used to pump the steam in the steam flow channel 133 towards the air outlet 111.

[0113] When the blower 170 operates, the blower 170 is used to pump the steam in the steam flow channel 133 towards the air outlet 111. Driven by the blower 170, 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 accumulating in a certain place, thereby avoiding the formation of condensed water.

[0114] An installation cavity 112 is provided on the base 110, and the blower 170 is installed in the installation cavity 112. The installation cavity 112 is used to communicate the steam outlet 153 and the air outlet 111. By arranging the blower 170 in the installation cavity 112, the air flow flowing into the installation cavity 112 basically comes from the steam outlet 153, and it is not easy for the blower 170 to pump out the air inside the base 110, so as to ensure that the steam in the steam flow channel 133 is discharged at a relatively high flow rate, and further avoid the formation of condensed water in the steam discharged from the cooking device.

[0115] In the embodiments 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, which will not be elaborated here.

[0116] Combined Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cooking device further includes: a steamer assembly 200, the steamer assembly 200 is arranged on the base assembly 100, the steamer assembly 200 has a cooking cavity 210, and both the steam supply port 122 and the steam inlet 121 are communicated with the cooking cavity 210.

[0117] The steamer assembly 200 can be placed on the water tank 151 or on the base 110, and the steam is discharged into the steamer assembly 200 through the steam supply port 122.

[0118] The steam generated by the steam generating assembly 120 is discharged into the cooking cavity 210 through the steam supply port 122. However, both the steam supply port 122 and the steam inlet 121 are provided on the juice collecting tray 152. In order to prevent the steam discharged from the steam supply port 122 into the cooking cavity 210 from directly flowing to the steam inlet 121, a steam return pipe 300 is installed on the steam inlet 121.

[0119] One end of the steam return pipe 300 is connected to the steam inlet 121, and the other end of the steam return pipe 300 extends to the top of the cooking cavity 210. After the steam flows into the cooking cavity 210 through the steam supply port 122, the steam rises in the cooking cavity 210. Since the height of the steam return pipe 300 is relatively high, the steam will flow into the steam return pipe 300 only when the steam flows to the top of the cooking cavity 210. Therefore, when a part of the steam flows to the top of the cooking cavity 210, the steam basically fills the cooking cavity 210, so that the temperature of each place in the cooking cavity 210 is relatively high, ensuring the uniform heating effect of the steam on the food.

[0120] By installing the steam reflux pipe 300 on the steam inlet 121, the steam is not likely to flow directly to the steam inlet 121, thereby ensuring that the steam can effectively heat the food.

[0121] In some embodiments, optionally, the steamer assembly 200 includes: a steamer 220 and a cover 230 , the steamer 220 is disposed on the base assembly 100 , and the cover 230 is covered on the steamer 220 , so that a closed space is formed in the cover 230 and the steamer 220 .

[0122] The food can be placed in the steamer 220, and the space between the cover 230 and the steamer 220 is the cooking cavity 210. When the cover 230 is covered in the steamer 220, the cover 230 and the steamer 220 are in a closed state, that is, the cover 230 is not provided with air holes for exhaust, so that the gas in the cooking cavity 210 will not be discharged to the outside through the cover 230, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged to the outside.

[0123] 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.

[0124] 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.

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.
