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 of cooking equipment, a large amount of high-temperature steam will be generated. The high-temperature steam carries a large amount of heat. When the steam is discharged outwards, the heat carried by the steam will also be lost, resulting in heat waste. Content 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 the 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 arranged 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. Wherein, the first side of the steam generating assembly faces the cooking cavity. The first side of the steam generating assembly includes a central part and an edge part. The edge part is distributed along the circumference of the central part. The steam supply port is arranged at the central part, and the steam inlet is arranged at the edge part; or the steam supply port and the steam inlet are arranged on both sides of the length direction or the width direction of the steam generating assembly.

[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. The steam generating assembly is provided with a steam supply port. 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. 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. 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 steam generating assembly for the water, thereby reducing the energy consumption of the steam generating assembly and being beneficial to improving the energy utilization rate.

[0007] To prevent the steam discharged from the steam supply port from directly flowing towards the steam inlet, the steam supply port and the steam inlet need to be set far apart from each other.

[0008] In a possible application, the first side of the steam generating assembly faces the cooking cavity. The steam supply port is arranged in the middle of the first side of the steam generating assembly, and the steam inlet is arranged at the edge position of the first side of the steam generating assembly, so that there is a large distance between the steam supply port and the steam inlet.

[0009] In a possible application, the steam supply port and the steam inlet are distributed on both sides of the length direction of the steam generating assembly, or the steam supply port and the steam inlet are distributed on both sides of the width direction of the steam generating assembly, so that there is a large distance between the steam supply port and the steam inlet.

[0010] In the above manner, the steam discharged from the steam supply port into the cooking cavity is not likely to directly flow towards the steam inlet, ensuring that the steam can effectively heat the ingredients in the cooking area.

[0011] In addition, according to the base assembly in the above technical solution provided by the present utility model, the following additional technical features may also be included:

[0012] In some technical solutions, optionally, the steam flowing back into the steam flow channel is used to be discharged to the outside through the end of the steam flow channel.

[0013] 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 flow channel is connected to the outside of the cooking device, that is, the steam in the steam flow channel 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.

[0014] In some technical solutions, optionally, the inner cavity is used to store water, the steam flow channel is connected to 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.

[0015] In this solution, it is defined that the steam flow channel is connected to the inner cavity, that is, there is an opening at the bottom of the steam flow channel, and the steam flow channel is connected to 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 connected to 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.

[0016] In some technical solutions, optionally, the steam supply port and the steam flow channel are independent of each other.

[0017] The steam generated by the steam generation 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 easily discharged back into the cooking cavity through the steam supply port, thereby preventing the steam discharged into the cooking cavity from mixing with the steam flowing back into the steam flow channel and ensuring the independence of the steam for heating and the steam for discharging outward.

[0018] In some technical solutions, optionally, the first end and the second end of the steam flow channel are staggeredly distributed in the length direction and the width direction of the steam generation assembly.

[0019] Both ends of the steam flow channel are distributed along the length direction of the steam generation assembly and also along the width direction of the steam generation assembly, such that the two ends of the steam generation assembly tend to be distributed diagonally along the steam generation assembly. Steam can flow within the steam flow channel. In the above situation, the distribution positions of the two ends of the steam generation assembly can enable the steam to flow within the steam flow channel for a longer duration, which is beneficial to improving the steam cooling effect.

[0020] In some technical solutions, optionally, the steam generation assembly includes: a water tank; a juice tray connected to the water tank, with an inner cavity located between the juice tray and the water tank, a steam inlet and a steam supply port provided on the juice tray, and the cooking cavity located above the juice tray.

[0021] Water is stored in the water tank. The juice tray is arranged at the opening position of the water tank, and an inner cavity is formed between the juice tray and the water tank. When the steam generation assembly operates, 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 tray. Since the cooking cavity is located above the juice tray, the steam discharged from the steam supply port directly enters the cooking cavity, thereby ensuring that high-temperature steam can quickly heat the food ingredients.

[0022] The cooking cavity is located above the juice tray. During the cooking process, the juice tray is used to receive and collect the juice flowing from the food ingredients, facilitating the user to centrally process the juice flowing from the food ingredients and being beneficial to improving the convenience of the user in using the cooking device. After using the juice tray as the enclosing component of the inner cavity, there is no need to additionally set components cooperating with the water tank, which is beneficial to simplifying the structure of the cooking device.

[0023] In some technical solutions, optionally, the steam inlet protrudes from the side of the juice tray facing the cooking cavity.

[0024] The top of the juice tray is used to receive the juice of the food ingredients. The steam inlet is higher than the top of the juice tray, and the juice of the food ingredients is not easily introduced into the steam inlet, preventing the juice of the food ingredients from contaminating the water stored in the inner cavity.

[0025] In some technical solutions, optionally, the steam generation assembly further includes: a flow guide member located in the inner cavity, and a steam flow channel is provided on the flow guide member.

[0026] A steam flow channel is provided on the flow guide member, and the flow guide member is used to guide the recovered steam so that the steam can flow along the flow guide member. Under the guiding action of the flow guide member, the steam exchanges heat with the water in the inner cavity along a set route.

[0027] In some technical solutions, optionally, a part of the flow guide member is immersed in the water in the inner cavity.

[0028] The flow guide member is used to extend into 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.

[0029] In a possible application, a part of the flow guide member is immersed in the water in the inner cavity, so that the water can exchange heat with the flow guide member. In the case of steam flowing in the steam, the steam can indirectly exchange heat with the water through the flow guide member.

[0030] Alternatively, an opening is provided at the bottom of the flow guide member, so that the steam flow channel in the flow guide member is in direct contact with the water, thereby enabling the steam to directly exchange heat with the water. A part of the flow guide member is immersed in the water, and the water plays a blocking role on the steam, ensuring that the steam can only flow in the steam flow channel and is not likely to flow out of the steam flow channel. That is, it can ensure that the steam can stably exchange heat with the water and also ensure that the steam flow channel can stably guide the steam.

[0031] In some technical solutions, optionally, the distance between the steam inlet and the outer contour of the juice collecting tray is L1, and L1 satisfies L1 ≤ 50 mm.

[0032] The steam in the cooking cavity flows through the steam inlet to the steam flow channel. The closer the steam inlet is to the outer contour of the juice collecting tray, the longer the time for the steam in the cooking cavity to flow to the steam inlet.

[0033] Specifically, the distance between the steam inlet and the outer contour of the juice collecting tray is L1, and L1 ≤ 50 mm. Therefore, the distance between the steam inlet and the outer contour of the juice collecting tray is small, and the steam inlet is far from the middle of the juice collecting tray. When the steam flows upward to the top of the cooking cavity, the steam does not directly pass through the steam inlet. When the steam reaches the top of the cooking cavity and then flows along the top of the cooking cavity to the side of the cooking cavity for a certain distance, the steam will flow to the steam inlet. By the above method, the flow time of the steam in the cooking cavity is increased, which is beneficial to ensuring a relatively high temperature in the cooking cavity and improving the heating effect on the food ingredients.

[0034] In some technical solutions, optionally, the distance between the orthographic projection of the steam inlet on the juice collecting tray and the steam supply port is L2, and L2 satisfies L2 ≥ 50 mm.

[0035] The steam in the cooking cavity flows through the steam inlet towards the steam flow channel. The steam inlet and the steam supply port have a positive projection on the juice collector tray. The greater the distance between the positive projections of the two, the longer the time for the steam in the cooking cavity to flow towards the steam flow channel.

[0036] For example, when the steam supply port is arranged in the middle of the juice collector tray, if the distance between the positive projection of the steam inlet on the juice collector tray and the steam supply port is small, it means that the steam inlet is close to the middle of the juice collector tray. When the steam flows towards the top of the cooking cavity, the steam will directly pass through the steam inlet, resulting in a short flow time of the steam in the cooking cavity.

[0037] In this embodiment, it is defined that the distance between the projection of the steam inlet on the juice collector tray and the steam supply port is L2, and L2≥50mm. In this range, the steam inlet is far from the middle of the juice collector tray. During the process of the steam flowing towards the top of the cooking cavity, the steam will not directly pass through the steam inlet. When the steam flows to the top of the cooking cavity, the steam will flow along the top of the cooking cavity towards the side of the cooking cavity for a certain distance before flowing towards the steam inlet. By the above method, the flow duration of the steam in the cooking cavity is increased, which is beneficial to ensuring a high temperature in the cooking cavity and improving the heating effect on the food materials.

[0038] 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.

[0039] The lowest liquid level line is provided on the inner cavity, which plays a role in prompting the user. When the liquid level of the water in the inner cavity is approaching the lowest 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.

[0040] A part of the steam flow channel is lower than the lowest liquid level line. Even when the liquid level height in the inner cavity is already 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 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, avoiding the accumulation of some recycled steam in the steam generating component.

[0041] 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.

[0042] A part of the steam flow channel is higher than the highest liquid level line. Even when the liquid level height 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. The space in the steam flow channel higher than the liquid level is for the steam to flow.

[0043] When the user fills the inner cavity with water, 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 steam can flow and exchange heat in the steam flow channel.

[0044] In some technical solutions, optionally, a part of the juice receiving tray extends out of the side of the base, and a steam outlet is provided on a part of the juice receiving tray extending out of the side of the base, and the steam outlet is communicated with the steam flow channel.

[0045] The steam outlet is arranged on the side 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 set an outlet for steam discharge on the water tank, which can reduce the processing difficulty of the water tank.

[0046] 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.

[0047] 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 flow channel is communicated with the air outlet.

[0048] The steam generating assembly is installed in the base, and the base plays a protective role for the steam generating assembly. The steam can be discharged outward through the air outlet on the base.

[0049] In some technical solutions, optionally, the base assembly further includes: a fan, connected to the base, and the fan is used to pump the steam in the steam flow channel towards the air outlet.

[0050] 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.

[0051] An installation cavity is provided on the base, the fan is located in the installation cavity, and the steam flow channel is communicated with the air outlet through the installation cavity.

[0052] An installation cavity is provided on the base. The fan is installed in the installation cavity. The installation cavity is used to connect the steam outlet and the air outlet. By setting the fan in the installation cavity, the air flow flowing into the installation cavity basically comes from the steam flow channel, and it is not easy for the fan to extract the air inside the base, so as to ensure that the steam in the steam flow channel is discharged at a relatively high flow rate, and further avoid the formation of condensate water from the steam discharged from the cooking device.

[0053] In some technical solutions, optionally, the base assembly further includes: a filter screen located in the steam flow channel. Along the extending direction of the steam flow channel, at least one filter screen is provided in the steam flow channel.

[0054] Steam can pass through the filter screen, but the filter screen can reduce the flow rate of the steam in the steam flow channel, thereby prolonging the flow duration of the steam in the steam flow channel, and further increasing the heat exchange duration between the steam and water.

[0055] In a second aspect, the present utility model proposes a cooking device including the base assembly as in the second aspect.

[0056] In some technical solutions, optionally, the cooking device further includes: a steamer assembly having a cooking cavity, and the steam supply port and the steam inlet are both connected to the cooking cavity.

[0057] A steam flow channel is provided on one side of the juice receiving tray. The steam can heat the food ingredients 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, and the steam flowing back into the steam flow channel is used for heat exchange with the chamber generating the steam, thereby realizing the recovery of the heat of the steam and avoiding waste of the heat of the steam.

[0058] In some technical solutions, optionally, the cooking device further includes: a steam return pipe. The first end of the steam return pipe is connected to the steam inlet, and the second end of the steam return pipe extends towards the top of the cooking cavity.

[0059] One end of the steam return pipe is connected to the steam inlet, and the other end of the steam return pipe extends to the top of the cooking cavity. After the steam flows into the cooking cavity through the steam supply port, the steam will rise in the cooking cavity. Due to the relatively high height of the steam return pipe, the steam will only flow into the steam return pipe when the steam flows to the top of the cooking cavity. Therefore, when a part of the steam flows to the top of the cooking cavity, the steam basically fills the cooking cavity, making the temperature everywhere in the cooking cavity relatively high and ensuring the uniform heating effect of the steam on the food ingredients.

[0060] By installing a steam return pipe on the steam inlet, the steam is not easy to directly flow towards the steam inlet, ensuring that the steam can effectively heat the food ingredients.

[0061] In some technical solutions, optionally, the steamer assembly includes: a steamer disposed on the base assembly; and a cover covering the steamer to form a closed space between the cover and the steamer.

[0062] Food ingredients can be placed in the steamer, and the space between the cover and the steamer is the cooking chamber. When the cover is placed inside the steamer, the space between the cover and the steamer is in a closed state, that is, no air vents for exhausting gas are provided on the cover, so that the gas in the cooking chamber will not be discharged outward through the cover, 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

[0075] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying 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.

[0076] 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.

[0077] The following refers to Figures 1 to 8 Describe a base assembly and a cooking device provided according to some embodiments of the present invention.

[0078] Combined with Figure 2 、 Figure 3 And Figure 4 As shown in, in an embodiment of the present invention, a base assembly 100 is proposed. The base assembly 100 is used for a cooking device. The cooking device has a cooking cavity 210. The base assembly 100 includes: a base 110 and a steam generation assembly 120. The steam generation assembly 120 is connected to the base 110. The steam generation assembly 120 is provided with a steam inlet 121, a steam supply port 122 and an inner cavity 123. A steam flow channel 136 is provided in the inner cavity 123. The steam inlet 121 is communicated with the steam flow channel 136. The steam generated by the steam generation 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 136. The first side of the steam generation assembly 120 faces the cooking cavity 210. The first side of the steam generation assembly 120 includes a central part 124 and an edge part 125. The edge part 125 is along the circumferential direction of the central part 124 ( Figure 3The arrow at position C points to) the distribution, the steam supply port 122 is provided at the central portion 124, and the steam inlet 121 is provided at the edge portion 125; or the steam supply port 122 and the steam inlet 121 are provided on both sides of the length direction ( Figure 4 The arrow at position X points to) or both sides of the width direction ( Figure 4 The arrow at position Y points to).

[0079] In the base assembly 100 provided in this embodiment, the steam generating assembly 120 is disposed 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. A steam supply port 122 is provided on the steam generating assembly 120, and 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 ingredients in the cooking cavity 210 can be heated.

[0080] A steam flow channel 136 is provided in the inner cavity 123, and the steam can heat the ingredients 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 136 through the steam inlet 121. Since there is water in the inner cavity 123, the steam flowing into the steam flow channel 136 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, thereby realizing the recovery of the steam heat and avoiding waste of the steam heat. Also, 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.

[0081] Figure 2 In, the arrows in the cooking device are used to indicate the steam flow direction. Figure 4 The arrow in the steam flow channel 136 is used to indicate the steam flow direction.

[0082] In order to prevent the steam discharged from the steam supply port 122 from directly flowing to the steam inlet 121, the steam supply port 122 and the steam inlet 121 need to be set far away from each other.

[0083] In a possible application, the first side of the steam generating assembly 120 faces the cooking cavity 210, the steam supply port 122 is provided in the middle of the first side of the steam generating assembly 120, and the steam inlet 121 is provided at the edge position of the first side of the steam generating assembly 120, so that there is a large distance between the steam supply port 122 and the steam inlet 121.

[0084] In a possible application, the steam supply port 122 and the steam inlet 121 are distributed on both sides of the steam generating assembly 120 in the length direction, or the steam supply port 122 and the steam inlet 121 are distributed on both sides of the steam generating assembly 120 in the width direction, so that there is a relatively large distance between the steam supply port 122 and the steam inlet 121.

[0085] In this way, the steam discharged from the steam supply port 122 into the cooking cavity 210 is not likely to directly flow to the steam inlet 121, ensuring that the steam can effectively heat the food ingredients in the cooking area.

[0086] In some embodiments, optionally, the steam flowing back into the steam flow channel 136 is used to be discharged to the outside through the end of the steam flow channel 136.

[0087] Since there is water in the inner cavity 123, the steam flowing into the steam flow channel 136 can directly or indirectly exchange heat with the water, thereby reducing the temperature of the steam. The steam flow channel 136 is connected to the outside of the cooking device, that is, the steam in the steam flow channel 136 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.

[0088] In some embodiments, optionally, the inner cavity 123 is used to store water, the steam flow channel 136 is connected to the inner cavity 123, and the steam flowing back into the steam flow channel 136 is used to contact and exchange heat with the water in the inner cavity 123.

[0089] In this solution, it is defined that the steam flow channel 136 is connected to the inner cavity 123, that is, an opening is provided at the bottom of the steam flow channel 136, and the steam flow channel 136 is connected to the inner cavity 123 through the opening. After the steam flows into the steam flow channel 136, the steam in the steam flow channel 136 exchanges heat with the water in the inner cavity 123. Since the steam flow channel 136 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.

[0090] In some embodiments, optionally, the steam supply port 122 and the steam flow channel 136 are independent of each other.

[0091] The steam generated by the steam generating assembly 120 is discharged into the cooking cavity 210 through the steam supply port 122. When the steam supply port 122 and the steam flow channel 136 are set to be independent of each other, the steam flowing back into the steam flow channel 136 is not likely to be discharged into the cooking cavity 210 again through the steam supply port 122, thereby preventing the steam discharged into the cooking cavity 210 from mixing with the steam flowing back into the steam flow channel 136 and ensuring the independence of the steam for heating and the steam for outward discharge.

[0092] Combined with Figure 3 and Figure 8 As shown, in some embodiments, optionally, the first end and the second end of the steam flow channel 136 are staggeredly distributed in the length direction and the width direction of the steam generating assembly 120.

[0093] Both ends of the steam flow channel 136 are distributed along the length direction of the steam generating assembly 120 and also along the width direction of the steam generating assembly 120, such that the two ends of the steam generating assembly 120 tend to be distributed diagonally along the steam generating assembly 120. Steam can flow in the steam flow channel 136. In the above situation, the distribution positions of the two ends of the steam generating assembly 120 can enable the steam to flow in the steam flow channel 136 for a longer time, which is beneficial to improving the cooling effect on the steam.

[0094] Combined with Figure 2 、 Figure 3 and Figure 7 As shown, in some embodiments, optionally, the steam generating assembly 120 includes: a water tank 126 and a juice receiving tray 127. The juice receiving tray 127 is connected to the water tank 126. The inner cavity 123 is located between the juice receiving tray 127 and the water tank 126. The steam inlet 121 and the steam supply port 122 are provided on the juice receiving tray 127, and the cooking cavity 210 is located above the juice receiving tray 127.

[0095] The water tank 126 is used for storing water. The juice receiving tray 127 is arranged at the opening position of the water tank 126. An inner cavity 123 is formed between the juice receiving tray 127 and the water tank 126. When the steam generating assembly 120 operates, the water in the water tank 126 is heated. After steam is generated in the water tank 126, the steam is discharged into the cooking cavity 210 through the steam supply port 122 on the juice receiving tray 127. Since the cooking cavity 210 is located above the juice receiving tray 127, 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.

[0096] The cooking cavity 210 is located above the juice collecting tray 127. During the cooking process, the juice collecting tray 127 is used to collect the juice flowing from the ingredients, facilitating the user to centrally process the juice flowing from the ingredients and improving the convenience of using the cooking device for the user. After using the juice collecting tray 127 as an enclosure component of the inner cavity 123, there is no need to additionally set up components cooperating with the water tank 126, which is conducive to simplifying the structure of the cooking device.

[0097] The steam generating assembly 120 further includes: a heater 134, which is disposed on the water tank 126 or the base 110. The heater 134 faces the steam generating cavity 129, and the heater 134 is used to heat the water in the steam generating cavity 129.

[0098] Combined Figure 2 and Figure 6 As shown in the figure, in some embodiments, optionally, the cooking device further includes: a partition member 135, which is located in the inner cavity 123. The partition member 135 is used to separate the steam supply port 122 and the steam flow channel 136.

[0099] A partition member 135 is provided in the inner cavity 123. The partition member 135 can separate the steam supply port 122 and the steam flow channel 136, making it difficult for the steam flowing towards the steam supply port 122 and the steam in the steam flow channel 136 to mix with each other. Therefore, the steam generated by heating the water is not likely to flow into the steam flow channel 136, and the steam flowing back into the steam flow channel 136 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 136 are two parts of steam that are approximately independent of each other, thereby ensuring that the steam discharged into the cooking cavity 210 has a relatively high temperature and ensuring the heating effect on the ingredients.

[0100] The partition member 135 is directly placed in the water tank 126, or the partition member 135 is connected to the water tank 126.

[0101] A steam generating cavity 129 is formed in the partition member 135. The steam generating cavity 129 is communicated with the steam supply port 122, and the inner cavity 123 is communicated with the steam generating cavity 129.

[0102] A steam generating cavity 129 is provided in the partition member 135. The steam generating cavity 129 is communicated with the steam supply port 122. The water in the steam generating cavity 129 will generate steam after being heated, and the steam in the steam generating cavity 129 is discharged into the cooking cavity 210 through the steam supply port 122. The partition member 135 can define a steam generating cavity 129, and the water stored in the steam generating cavity 129 is less. Therefore, the small amount of water in the steam generating cavity 129 can be quickly heated into steam, which is conducive to increasing the steam generation speed and further conducive to improving the heating effect on the ingredients.

[0103] The water inlet hole 130 is provided on the partition member 135. The water inlet hole 130 is used to communicate the steam generation chamber 129 and the inner cavity 123. The water in the inner cavity 123 can be injected into the steam generation chamber 129 through the water inlet hole 130. When the water in the steam generation chamber 129 is heated into steam, the water in the inner cavity 123 is replenished into the steam generation chamber 129 through the water inlet hole 130, preventing the water in the steam generation chamber 129 from being dried up. According to the principle of communicating vessels, the liquid level height in the steam generation chamber 129 and the liquid level height in the inner cavity 123 are basically the same, thus ensuring that a small amount of water is maintained in the steam generation chamber 129.

[0104] As Figure 3 shown, in some embodiments, optionally, the steam inlet 121 protrudes from the side of the juice collecting tray 127 facing the cooking cavity 210.

[0105] The top of the juice collecting tray 127 is used to hold the juice of the ingredients. The steam inlet 121 is higher than the top of the juice collecting tray 127, so that the juice of the ingredients is not easily introduced into the steam inlet 121, preventing the juice of the ingredients from contaminating the stored water in the inner cavity 123.

[0106] In a possible application, the juice collecting tray 127 is placed on the water tank 126, which facilitates the user to lift the juice collecting tray 127 to pour out the juice and also facilitates the user to clean the inside of the water tank 126.

[0107] Combined Figure 2 and Figure 5 shown, in some embodiments, optionally, the steam generating assembly 120 further includes: a flow guiding member 128, located in the inner cavity 123, and a steam flow channel 136 is provided on the flow guiding member 128.

[0108] The steam flow channel 136 is provided on the flow guiding member 128. The flow guiding member 128 is used to guide the recycled steam so that the steam can flow along the flow guiding member 128. Under the guiding action of the flow guiding member 128, the steam exchanges heat with the water in the inner cavity 123 along a set route.

[0109] In a possible application, the flow guiding member 128 is connected to the juice collecting tray 127.

[0110] In some embodiments, optionally, a part of the flow guiding member 128 is immersed in the water in the inner cavity 123.

[0111] The flow guiding member 128 is used to extend into the inner cavity 123, and the steam flowing back into the steam flow channel 136 is used to contact and exchange heat with the water in the inner cavity 123.

[0112] In a possible application, a part of the flow guide member 128 is immersed in the water in the inner cavity 123, so that the water can exchange heat with the flow guide member 128. When steam flows in the steam, the steam can indirectly exchange heat with the water through the flow guide member 128.

[0113] Alternatively, an opening is provided at the bottom of the flow guide member 128, so that the steam flow channel 136 in the flow guide member 128 is in direct contact with the water, so that the steam directly exchanges heat with the water. A part of the flow guide member 128 is immersed in the water, and the water plays a blocking role on the steam, ensuring that the steam can only flow in the steam flow channel 136, and the steam is not easy to flow out of the steam flow channel 136. 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 136 can stably guide the steam.

[0114] In some embodiments, optionally, the distance between the steam inlet 121 and the outer contour of the juice receiving tray 127 is L1, and L1 satisfies L1 ≤ 50 mm.

[0115] The steam in the cooking cavity 210 flows through the steam inlet 121 to the steam flow channel 136. The closer the steam inlet 121 is to the outer contour of the juice receiving tray 127, the longer the time for the steam in the cooking cavity 210 to flow to the steam inlet 121.

[0116] Specifically, the distance between the steam inlet 121 and the outer contour of the juice receiving tray 127 is L1, and L1 ≤ 50 mm. Therefore, the distance between the steam inlet 121 and the outer contour of the juice receiving tray 127 is small, and the steam inlet 121 is far from the middle of the juice receiving tray 127. When the steam flows to the top of the cooking cavity 210, the steam does not directly pass through the steam inlet 121. When the steam reaches the top of the cooking cavity 210, the steam will flow to the steam inlet 121 only after flowing along the top of the cooking cavity 210 to the side of the cooking cavity 210 for a certain distance. By the above method, the flow time of the steam in the cooking cavity 210 is increased, which is beneficial to ensuring a higher temperature in the cooking cavity 210 and improving the heating effect on the food ingredients.

[0117] In some embodiments, optionally, the distance between the orthographic projection of the steam inlet 121 on the juice receiving tray 127 and the steam supply port 122 is L2, and L2 satisfies L2 ≥ 50 mm.

[0118] The steam in the cooking cavity 210 flows through the steam inlet 121 to the steam flow channel 136. The steam inlet 121 and the steam supply port 122 have orthographic projections on the juice receiving tray 127. The greater the distance between the two orthographic projections, the longer the time for the steam in the cooking cavity 210 to flow to the steam inlet.

[0119] For example, when the steam supply port 122 is provided in the middle of the juice receiving tray 127, if the distance between the orthographic projection of the steam inlet 121 on the juice receiving tray 127 and the steam supply port 122 is small, it indicates that the steam inlet 121 is close to the middle of the juice receiving tray 127. When the steam flows towards the top of the cooking cavity 210, the steam will directly pass through the steam inlet 121, resulting in a short flow time of the steam in the cooking cavity 210.

[0120] In this embodiment, it is defined that the distance between the projection of the steam inlet 121 on the juice receiving tray 127 and the steam supply port 122 is L2, and L2≥50mm. In this range, the steam inlet 121 is far from the middle of the juice receiving tray 127. During the process of the steam flowing towards the top of the cooking cavity 210, the steam will not directly pass through the steam inlet 121. When the steam flows to the top of the cooking cavity 210, the steam will flow along the top of the cooking cavity 210 towards the side of the cooking cavity 210 for a certain distance before flowing towards the steam inlet 121. By the above method, the flow duration of the steam in the cooking cavity 210 is increased, which is beneficial to ensuring a high temperature in the cooking cavity 210 and improving the heating effect on the food ingredients.

[0121] As Figure 7 shown, in some embodiments, optionally, a lowest liquid level line 132 is provided on the inner cavity 123. Based on the bottom wall of the inner cavity 123, a part of the steam flow channel 136 is lower than the lowest liquid level line 132.

[0122] The lowest liquid level line 132 is provided on the inner cavity 123, and the lowest liquid level line 132 plays a role in prompting the user. When the liquid level of the water in the inner cavity 123 approaches the lowest liquid level line 132, the user needs to inject water into the inner cavity 123 to avoid the problem of dry burning of the steam generating assembly 120.

[0123] A part of the steam flow channel 136 is lower than the lowest liquid level line 132. Even when the liquid level in the inner cavity 123 is already close to the lowest liquid level line 132, a part of the water in the inner cavity 123 is still higher than the bottom of the steam flow channel 136. The water blocks the steam, ensuring that the steam can only flow in the steam flow channel 136. It is not easy for the steam to flow out of the steam flow channel 136. 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 136 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 120.

[0124] As Figure 7 shown, in some embodiments, optionally, a highest liquid level line 131 is provided on the inner cavity 123. Based on the bottom wall of the inner cavity 123, a part of the steam flow channel 136 is higher than the highest liquid level line 131.

[0125] A part of the steam flow channel 136 is higher than the highest liquid level line 131. Even when the liquid level in the inner cavity 123 has reached the highest liquid level line 131, a part of the space in the steam flow channel 136 is still higher than the liquid level in the inner cavity 123, and the space in the steam flow channel 136 above the liquid level is for steam to flow.

[0126] When the user fills water into the inner cavity 123, the water in the inner cavity 123 usually does not exceed the highest liquid level line 131, and a part of the steam flow channel 136 is higher than the highest liquid level line 131. Therefore, it can be ensured that a part of the space in the steam flow channel 136 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 136.

[0127] As Figure 8 shown, in some embodiments, optionally, a part of the juice receiving tray 127 extends out of the side of the base 110, and a steam outlet 133 is provided on a part of the juice receiving tray 127 extending out of the side of the base 110, and the steam outlet 133 is communicated with the steam flow channel 136.

[0128] The steam outlet 133 is provided on the side of the juice receiving tray 127. Therefore, the steam in the steam flow channel 136 can be directly discharged outward through the steam outlet 133 on the juice receiving tray 127. Both the steam inlet 121 and the steam outlet 133 are provided on the juice receiving tray 127. Therefore, there is no need to provide an outlet for steam discharge on the water tank 126, which can reduce the processing difficulty of the water tank 126.

[0129] In a possible application, the opening of the steam outlet 133 faces upward. When the steam is discharged from the steam outlet 133, 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.

[0130] Combined with Figure 2 and Figure 7 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, and the steam flow channel 136 is communicated with the air outlet 111.

[0131] The steam generating assembly 120 is installed in the base 110, and the base 110 plays a protective role for the steam generating assembly 120, and the steam can be discharged outward through the air outlet 111 on the base 110.

[0132] Combined with Figure 2 and Figure 7 shown, in some embodiments, optionally, the base assembly 100 further includes: a blower 140, the blower 140 is connected to the base 110, and the blower 140 is used to pump the steam in the steam flow channel 136 towards the air outlet 111.

[0133] When the fan 140 operates, the fan 140 is used to pump the steam in the steam flow channel 136 towards the air outlet 111. Driven by the fan 140, the steam is discharged to the outside of the cooking device at a relatively high flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is large, and the water molecules in the steam quickly mix with the air, making it difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules aggregating in a certain place, thus avoiding the formation of condensed water.

[0134] An installation cavity 112 is provided on the base 110. The fan 140 is located in the installation cavity 112, and the steam flow channel 136 is connected to the air outlet 111 through the installation cavity 112.

[0135] An installation cavity 112 is provided on the base 110. The installation cavity 112 is used to install the fan 140, and the installation cavity 112 is used to connect the steam outlet 133 and the air outlet 111. By arranging the fan 140 in the installation cavity 112, the air flow flowing into the installation cavity 112 basically comes from the steam flow channel 136, and it is not easy for the fan 140 to extract the air inside the base 110, so as to ensure that the steam in the steam flow channel 136 is discharged at a relatively high flow rate, further avoiding the formation of condensed water in the steam discharged from the cooking device.

[0136] As Figure 4 shown, in some embodiments, optionally, the base assembly 100 further includes: a filter screen 150. The filter screen 150 is located in the steam flow channel 136, and along the extending direction of the steam flow channel 136, at least one filter screen 150 is provided in the steam flow channel 136.

[0137] The steam can pass through the filter screen 150, but the filter screen 150 can reduce the flow rate of the steam in the steam flow channel 136, thereby prolonging the flow duration of the steam in the steam flow channel 136, and further increasing the heat exchange duration between the steam and water.

[0138] Combined Figure 1 and Figure 2 shown, in the embodiments of the present invention, 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.

[0139] In some embodiments, optionally, the cooking device further includes: a steamer assembly 200. The steamer assembly 200 has a cooking cavity 210, and both the steam supply port 122 and the steam inlet 121 are connected to the cooking cavity 210.

[0140] A steam flow channel 136 is provided on one side of the juice receiving tray 127, and the steam can heat the food 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 136 from the steam inlet 121, and the steam flowing back into the steam flow channel 136 is used for heat exchange with the chamber that generates steam, thereby realizing the recovery of steam heat and avoiding waste of steam heat.

[0141] like Figure 2 As shown, in some embodiments, optionally, the cooking device further includes: a steam return pipe 300 , a first end of the steam return pipe 300 is connected to the steam inlet 121 , and a second end of the steam return pipe 300 extends toward the top of the cooking cavity 210 .

[0142] 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.

[0143] 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.

[0144] like Figure 2 As shown, in some embodiments, optionally, the distance between the second end of the steam reflux pipe 300 and the cavity side wall of the cooking cavity 210 is L1, and L1 satisfies, L1≤50mm.

[0145] The steam in the cooking cavity 210 flows to the steam flow channel 136 through the second end of the steam return pipe 300. The closer the second end of the steam return pipe 300 is to the side wall of the cooking cavity 210, the longer the steam in the cooking cavity 210 flows to the steam return pipe 300.

[0146] Specifically, the distance between the second end of the steam return pipe 300 and the side wall of the cooking cavity 210 is L1, and L1 ≤ 50 mm. Therefore, the distance between the second end of the steam return pipe 300 and the side wall of the cooking cavity 210 is small. The second end of the steam return pipe 300 is far from the upper part of the middle of the juice receiving tray 127. When the steam flows towards the top of the cooking cavity 210, the steam will not directly pass through the second end of the steam return pipe 300. When the steam flows to the top of the cooking cavity 210, the steam will flow along the top of the cooking cavity 210 towards the side of the cooking cavity 210 for a certain distance before flowing into the steam return pipe 300. By the above method, the flow duration of the steam in the cooking cavity 210 is increased, which is beneficial to ensuring a relatively high temperature in the cooking cavity 210 and improving the heating effect on the food ingredients.

[0147] As Figure 3 shown, in some embodiments, optionally, the distance between the positive projection of the second end of the steam return pipe 300 on the juice receiving tray 127 and the steam supply port 122 is L2, and L2 satisfies L2 ≥ 50 mm.

[0148] The steam in the cooking cavity 210 flows towards the steam flow channel 136 through the second end of the steam return pipe 300. The second end of the steam flow channel 136 has a positive projection on the juice receiving tray 127. The greater the distance between the positive projection and the steam supply port 122, the longer the time for the steam in the cooking cavity 210 to flow towards the steam return pipe 300.

[0149] For example, when the steam supply port 122 is arranged in the middle of the juice receiving tray 127, if the distance between the positive projection of the second end of the steam return pipe 300 on the juice receiving tray 127 and the steam supply port 122 is small, it means that the second end of the steam return pipe 300 is close to the upper part of the middle of the juice receiving tray 127. When the steam flows towards the top of the cooking cavity 210, the steam will directly pass through the second end of the steam return pipe 300, resulting in a shorter flow time of the steam in the cooking cavity 210.

[0150] In this embodiment, it is defined that the distance between the projection of the second end of the steam return pipe 300 on the juice receiving tray 127 and the steam supply port 122 is L2, and L2 ≥ 50 mm. In this range, the second end of the steam return pipe 300 is far from the upper part of the middle of the juice receiving tray 127. When the steam flows towards the top of the cooking cavity 210, the steam will not directly pass through the second end of the steam return pipe 300. When the steam flows to the top of the cooking cavity 210, the steam will flow along the top of the cooking cavity 210 towards the side of the cooking cavity 210 for a certain distance before flowing into the steam return pipe 300. By the above method, the flow duration of the steam in the cooking cavity 210 is increased, which is beneficial to ensuring a relatively high temperature in the cooking cavity 210 and improving the heating effect on the food ingredients.

[0151] In a possible application, L2 ≤ 100 mm.

[0152] 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 covers the steamer 220 to form a closed space within the cover 230 and the steamer 220.

[0153] Food ingredients can be placed in the steamer 220, and the space within the cover 230 and the steamer 220 is the cooking chamber 210. When the cover 230 covers the steamer 220, the interior of the cover 230 and the steamer 220 is in a closed state, that is, no air vents for exhausting are provided on the cover 230, so that the gas in the cooking chamber 210 will not be discharged outward through the cover 230, thereby ensuring that the cooking device can recover the heat of the steam and reducing the temperature of the steam discharged outward.
