Description

Technical Field

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

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

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

[0004] In view of this, in a first aspect, the utility model provides a steam recovery device for cooking equipment. The steam recovery device includes: a box body having a steam inlet, a steam outlet and a liquid storage cavity. The steam inlet is used to connect with the steam discharge port of the cooking equipment, and the liquid storage cavity is used to store a coolant; a flow guiding member connected to the box body and located in the liquid storage cavity. The flow guiding member is provided with a steam flow channel, the steam flow channel is communicated with the liquid storage cavity, and both the steam inlet and the steam outlet are communicated with the steam flow channel.

[0005] In the steam recovery device provided by the utility model, steam is generated during the operation of the cooking equipment. The cooking equipment has a cooking cavity, and the steam can heat the food ingredients in the cooking cavity. The steam in the cooking cavity can be discharged outwards through the steam discharge port. In order to prevent the high-temperature steam in the cooking cavity from directly discharging from the cooking cavity, a steam recovery device is installed outside the cooking cavity, and the steam recovery device is used to recover and process the steam discharged from the cooking cavity.

[0006] A steam inlet is provided on the box body, and the steam inlet is used to connect with the steam discharge port. Therefore, the steam in the cooking cavity can flow into the box body through the steam discharge port and the steam inlet. The flow guiding member is installed in the box body, and a steam flow channel is provided on the flow guiding member. One end of the steam flow channel is communicated with the steam inlet, and the steam in the cooking cavity can flow into the steam flow channel from one end of the steam flow channel. Since the steam flow channel is communicated with the liquid storage cavity, and there is a coolant in the liquid storage cavity, the steam flowing into the steam flow channel can exchange heat with the coolant, thereby reducing the temperature of the steam. The other end of the steam flow channel is communicated with the steam outlet, and the steam in the steam flow channel that has been cooled by heat exchange can be discharged from the box body. Since the temperature of the steam discharged from the box body is relatively low, users around the cooking appliance are not easily scalded by the steam, which is beneficial to improving the safety of users during the cooking process.

[0007] For the cooking appliances in the related art, the steam in the cooking cavity is directly discharged to the outside, which is likely to scald the users around the cooking appliances. The steam recovery device in this embodiment can be used as an independent structure and installed on the cooking appliances in the related art that do not have a steam recovery structure, enabling the cooking appliances in the related art to have the steam recovery function. Without major modifications to the cooking appliances in the related art, cooking appliances with the steam recovery function can be obtained, which is beneficial to reducing the processing difficulty of the cooking appliances.

[0008] The flow guide is located in the liquid storage cavity. The flow guide is used to guide the recovered steam so that the steam can flow along the flow guide. Under the guiding action of the flow guide, the steam exchanges heat with the coolant along a set route, and the steam after heat exchange can flow to the outside of the box body. The shape of the flow guide can be set according to the heat exchange requirements. By guiding the steam with the flow guide, it is beneficial to improve the heat exchange effect between the steam and the coolant.

[0009] In addition, for the steam recovery device according to the above technical solution provided by the present utility model, the following additional technical features may also be included:

[0010] In some technical solutions, optionally, the liquid storage cavity is used for storing water, the steam flow channel is connected to the liquid storage cavity, and the steam flowing back into the steam flow channel is used to contact and exchange heat with the coolant in the liquid storage cavity.

[0011] In this solution, it is defined that the steam flow channel is connected to the liquid storage cavity, that is, an opening is provided at the bottom of the steam flow channel, and the steam flow channel is connected to the liquid storage 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 liquid storage cavity. Since the steam flow channel is connected to the liquid storage 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 equipment has a lower temperature.

[0012] In some technical solutions, optionally, a part of the flow guide is immersed in the coolant.

[0013] A steam flow channel is provided on the flow guide. The flow guide is used to guide the recovered steam so that the steam can flow along the flow guide. Under the guiding action of the flow guide, 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 equipment.

[0014] A part of the flow guide is immersed in the water, so that the water can exchange heat with the flow guide. In the case of steam flowing in the steam, the steam can indirectly exchange heat with the water through the flow guide.

[0015] Alternatively, an opening is provided at the bottom of the flow guide member, such that the steam flow channel inside the flow guide member is in direct contact with water, thereby enabling direct heat exchange between the steam and the water. A part of the flow guide member is immersed in water, and the water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow channel and is not likely to flow out of the steam flow channel. That is, it can ensure stable heat exchange between the steam and the water, and also ensure that the steam flow channel can stably guide the steam, guaranteeing stable heat exchange between the steam and the water and ensuring that the steam flow channel can stably guide the steam.

[0016] In some technical solutions, optionally, a maximum liquid level line is provided on the liquid storage cavity. With the bottom wall of the liquid storage cavity as the reference plane, a part of the steam flow channel is higher than the maximum liquid level line.

[0017] A part of the steam flow channel is higher than the maximum liquid level line. Even when the liquid level in the liquid storage cavity has reached the maximum liquid level line, a part of the space inside the steam flow channel is still higher than the liquid level in the liquid storage cavity, and the space above the liquid level in the steam flow channel is for the steam to flow through.

[0018] When the user fills water into the liquid storage cavity, the water in the liquid storage cavity usually does not exceed the maximum liquid level line, and a part of the steam flow channel is higher than the maximum 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 guaranteeing that the steam can flow and exchange heat within the steam flow channel.

[0019] In some technical solutions, optionally, a minimum liquid level line is provided on the liquid storage cavity. With the bottom wall of the liquid storage cavity as the reference plane, a part of the steam flow channel is lower than the minimum liquid level line.

[0020] The minimum liquid level line is provided on the liquid storage cavity to serve as a reminder to the user. When the liquid level of the water in the liquid storage cavity approaches the minimum liquid level line, the user needs to fill water into the liquid storage cavity to avoid the problem of dry burning of the steam generating component.

[0021] A part of the steam flow channel is lower than the minimum liquid level line. Even when the liquid level in the liquid storage cavity is approaching the minimum liquid level line, a part of the water in the liquid storage cavity is still higher than the bottom of the steam flow channel, and the water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow channel and is not likely to flow out of the steam flow channel. That is, it can ensure stable heat exchange between the steam and the water, and also ensure that the steam flow channel can stably guide the steam, improving the heat exchange effect of the steam, ensuring that the steam can be stably discharged from the cooking device, and avoiding the accumulation of some recycled steam within the steam generating component.

[0022] In some technical solutions, optionally, a steam flow channel is formed by enclosing on the flow guide member; or a steam flow channel is formed between the flow guide member and the inner wall of the liquid storage cavity.

[0023] The steam flow channel can be independently formed on the flow guide member, or a steam flow channel is formed by enclosing between the flow guide member and the inner wall of the liquid storage cavity.

[0024] In some technical solutions, optionally, one side of the flow guide is connected to the top wall of the liquid storage cavity, and the other side of the flow guide is connected to the bottom wall of the liquid storage cavity; or one side of the flow guide is connected to the top wall of the liquid storage cavity, and the other side of the flow guide is spaced from the bottom wall of the liquid storage cavity.

[0025] The top of the flow guide is connected to the inner wall of the liquid storage cavity, and the bottom of the flow guide is also connected to the inner wall of the liquid storage cavity. The steam flowing into the box can only flow in the steam flow channel, preventing the steam located in the box from flowing out of the steam flow channel, so as to ensure that the steam can stably exchange heat with the coolant and ensure that the steam will be discharged from the box only after heat exchange.

[0026] Of course, it is also possible to set the top of the flow guide to be connected to the inner wall of the liquid storage cavity, and the bottom of the flow guide to be spaced from the inner wall of the liquid storage cavity. Since the liquid storage cavity stores coolant, when the coolant submerges the bottom of the flow guide, the coolant can block the steam in the steam flow channel, preventing the steam located in the box from flowing out of the steam flow channel, so as to ensure that the steam can stably exchange heat with the coolant and ensure that the steam will be discharged from the box only after heat exchange.

[0027] In some technical solutions, optionally, the steam flow channel is provided with at least one bent section, so that different parts of the steam flow channel extend at least in two directions.

[0028] Forming a bent section on the steam flow channel can extend the length of the steam flow channel, thereby increasing the flow duration of the steam in the steam flow channel, increasing the heat exchange duration between the steam and water, effectively reducing the temperature of the steam, and ensuring that the steam discharged from the cooking device is not likely to scald the user.

[0029] In some technical solutions, optionally, the steam flow channel includes a plurality of annular flow channels, and adjacent two annular flow channels are sleeved with each other, and the plurality of annular flow channels are sequentially connected.

[0030] The plurality of annular flow channels are used to guide the steam. Adjacent two annular flow channels are connected to each other, so that the steam can flow through the plurality of annular flow channels in sequence. The plurality of annular flow channels are in a sleeved relationship with each other, so that the plurality of annular flow channels can pass through most of the space in the box. When the steam flows into the annular flow channel, the steam can flow through most of the space in the box, which is beneficial to increasing the flow duration of the steam in the steam flow channel, thereby extending the heat exchange duration between the steam and the coolant, improving the heat recovery effect, further reducing the temperature of the steam discharged from the cooking appliance, and ensuring the safety of the user during the use of the cooking appliance.

[0031] In a possible application, adjacent two annular flow channels are connected through a communication port, and the adjacent two communication ports are located on both sides in the length direction or both sides in the width direction of the box.

[0032] The steam in the annular flow channel flows into the adjacent annular flow channel through the communication port. The adjacent communication ports are located on both sides in the length direction or both sides in the width direction of the box body. Therefore, the two adjacent communication ports are far away from each other, and the steam flowing into the annular flow channel needs to flow a relatively long distance before flowing into the next annular flow channel, which is beneficial to extending the flow path of the steam.

[0033] In some technical solutions, optionally, the box body includes: a water tank; a cover body detachably connected to the water tank. A liquid storage cavity is provided between the cover body and the water tank, and a guiding member is arranged on the water tank or the cover body.

[0034] The water tank is used to store the coolant, and the cover body is buckled at the opening position of the water tank. The cover body can be detached from the water tank, so that the water tank can be opened. After the steam recovery device is used, the cover body is detached from the water tank, and the user can clean the inside of the water tank to avoid the growth of bacteria in the water tank, ensure that the steam passing through the steam recovery device and discharged is not easily contaminated, and thus avoid the contamination of the cooking environment.

[0035] The guiding member can be installed on the cover body. After the cover body is detached, the guiding member is detached from the water tank together with the cover body, avoiding interference of the guiding member in the cleaning process of the inside of the water tank. Of course, the guiding member can also be arranged on the water tank.

[0036] In a possible application, the cover body can be locked to the water tank by structures such as screws and buckles. In order to ensure the sealing performance between the cover body and the water tank, a sealing member can be arranged between the cover body and the water tank. For example, the sealing member can be a rubber pad, a silica gel pad, etc.

[0037] In some technical solutions, optionally, the steam inlet and the steam outlet are arranged on the cover body; or the steam inlet and the steam outlet are arranged on the water tank; or one of the steam inlet and the steam outlet is arranged on the cover body, and the other is arranged on the water tank.

[0038] The steam inlet and the steam outlet can be arranged on the cover body at the same time. The cover body is located on the top of the water tank, and the coolant in the water tank is not easily overflowed through the steam inlet and the steam outlet.

[0039] Or, based on the relative positions between the steam recovery device and the main body of the cooking appliance, the steam inlet and the steam outlet can be arranged on the water tank at the same time according to the installation requirements.

[0040] Or, one of the steam inlet and the steam outlet can be arranged on the cover body, and the other can be arranged on the water tank.

[0041] In some technical solutions, optionally, along the extending direction of the steam flow channel, the length of the steam flow channel is greater than or equal to 1000 mm.

[0042] When the length of the steam flow channel is limited to be greater than or equal to 1000 mm, the steam flow channel has a relatively long length, and the flow time of steam in the steam flow channel is relatively long, thereby prolonging the heat exchange time between steam and water, improving the heat recovery effect, further reducing the temperature of the steam discharged from the cooking device, and ensuring the safety of users during the use of the cooking device.

[0043] In some technical solutions, optionally, the width W of the steam flow channel satisfies W≥5 mm.

[0044] The larger the width of the steam flow channel, the larger the heat exchange area between steam and the coolant. When the width of the steam flow channel is limited to be greater than or equal to 5 mm, the steam flow channel has a relatively large width, and the high-temperature steam can efficiently exchange heat with the coolant, improving the heat recovery effect, further reducing the temperature of the steam discharged from the box body, and ensuring the safety of users during the use of the cooking appliance.

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

[0046] When the fan operates, the fan is used to pump the steam in the steam flow channel towards the steam outlet. Driven by the fan, the steam is discharged to the outside of the cooking device at a relatively high flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is relatively large, and the water molecules in the steam quickly mix with the air, making it difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules aggregating in a certain place, thus avoiding the formation of condensed water.

[0047] In some technical solutions, optionally, an installation cavity is provided on the box body, the steam flow channel is provided with a flow channel outlet, and the flow channel outlet is communicated with the steam outlet through the installation cavity, and the fan is located in the installation cavity.

[0048] An installation cavity is provided on the base, and the fan is installed in the installation cavity. The installation cavity is used to communicate the flow channel outlet and the steam outlet. By arranging the fan in the installation cavity, the air flow flowing into the installation cavity basically comes from the flow channel outlet, and it is not easy for the fan to extract the air inside the base, thereby ensuring that the steam in the steam flow channel is discharged at a relatively high flow rate, and further avoiding the formation of condensed water in the steam discharged from the cooking device.

[0049] In some technical solutions, optionally, an air supplement hole is provided on the box body, and the air supplement hole is communicated with the installation cavity.

[0050] An air supplement hole is opened on the box body, and the air supplement hole is communicated with the installation cavity. When the fan operates, external gas can be supplemented into the installation cavity through the air supplement hole.

[0051] After the steam discharged from the steam flow channel is mixed with the external gas replenished through the air replenishing holes, the mixed gas is discharged through the steam outlet. The purpose of setting the air replenishing holes is to increase the air flow rate, reduce the temperature of the discharged steam, and at the same time reduce the negative pressure at the steam outlet, avoid the too-fast discharge speed of the steam in the steam flow channel, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0052] In some technical solutions, optionally, the opening area of the air replenishing holes is greater than or equal to the opening area of the steam outlet.

[0053] When the fan is operating, the opening area of the air replenishing holes will affect the negative pressure near the steam outlet. When the opening area of the air replenishing holes is greater than or equal to the opening area of the steam outlet, the air replenishing holes can provide sufficient external air for the fan, effectively reduce the negative pressure at the steam outlet, avoid the too-fast discharge speed of the steam in the steam flow channel, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0054] In some technical solutions, optionally, the wind speed V at the air outlet of the fan satisfies V≥1m / s.

[0055] In order to allow the steam in the steam flow channel to be discharged at a high speed into the ambient air at room temperature, 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, thus avoiding the formation of condensed water. To achieve the above effects, the wind speed at the air outlet of the fan is not less than 1m / s to meet the high-speed driving of the steam.

[0056] In some technical solutions, optionally, the opening area S of the steam outlet satisfies S≥50mm 2 。

[0057] The opening area of the steam outlet is greater than or equal to 50mm 2 , ensuring that the steam can be discharged smoothly and avoiding the accumulation of steam in the steam material.

[0058] In some technical solutions, optionally, the steam recovery device further includes: a filter screen, connected to the guiding member, and the filter screen is located in the steam flow channel.

[0059] The steam can pass through the filter screen, but the filter screen can reduce the flow speed 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.

[0060] In some technical solutions, optionally, the steam recovery device further includes: a connecting pipe, the first end of the connecting pipe is connected to the steam inlet, and the second end of the connecting pipe is used to connect to the steam discharge port.

[0061] The connecting pipe connects the steam discharge port and the steam inlet, enabling the steam in the cooking cavity to flow through the connecting pipe into the box body. By providing a connecting pipe between the main body part of the cooking appliance and the box body, the flexibility of the installation position of the box body can be improved. The box body does not need to be closely attached to the steam discharge port of the cooking cavity, which is beneficial to improving the space utilization rate of each component in the cooking appliance. In this way, the steam recovery device can be arranged outside the main body part of the cooking appliance. When the steam recovery device is not needed, the connecting pipe can be disassembled to separate the steam recovery device from the main body part of the cooking appliance, facilitating the use and storage of the cooking appliance.

[0062] In a second aspect, the present utility model provides a cooking device, including the steam recovery device as in the first aspect.

[0063] In some technical solutions, optionally, the cooking device further includes: a base; a steamer assembly arranged on the base, and the steam recovery device is arranged outside the base.

[0064] In some technical solutions, optionally, the steamer assembly includes: a steamer arranged on the base; a cover body covering the steamer to form a closed space inside the cover body and the steamer.

[0065] The 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 steamer, the inside of the cover body and the steamer is in a closed state, that is, no air vents for exhaust are provided on the cover body, so that the gas in the cooking cavity will not be discharged outward through the cover body, ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged outward.

[0066] The additional aspects and advantages of the present utility model will become obvious in the following description part, or be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0077] In order to be able to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below 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 may be combined with each other.

[0078] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0079] The following refers to Figures 1 to 7 Describe the steam recovery device and cooking equipment provided according to some embodiments of the present utility model.

[0080] Combined with Figure 1 、 Figure 2 And Figure 6As shown in the figure, in an embodiment of the present utility model, a steam recovery device 100 is proposed. The steam recovery device 100 is used for a cooking device. The steam recovery device 100 includes: a box body 110 and a flow guiding member 120. The box body 110 has a steam inlet 111, a steam outlet 112 and a liquid storage cavity 113. The steam inlet 111 is used to connect with the steam discharge port 310 of the cooking device, and the liquid storage cavity 113 is used to store coolant. The flow guiding member 120 is connected to the box body 110 and is located in the liquid storage cavity 113. The flow guiding member 120 is provided with a steam flow channel 121, and the steam flow channel 121 is communicated with the liquid storage cavity 113. Both the steam inlet 111 and the steam outlet 112 are communicated with the steam flow channel 121.

[0081] In the steam recovery device 100 provided in this embodiment, steam is generated during the operation of the cooking device. The cooking device has a cooking cavity, and the steam can heat the food ingredients in the cooking cavity. The steam in the cooking cavity can be discharged outward through the steam discharge port 310. In order to prevent the high-temperature steam in the cooking cavity from directly discharging from the cooking cavity, a steam recovery device 100 is installed outside the cooking cavity. The steam recovery device 100 is used to recover and process the steam discharged from the cooking cavity.

[0082] A steam inlet 111 is provided on the box body 110. The steam inlet 111 is used to connect with the steam discharge port 310. Therefore, the steam in the cooking cavity can flow into the box body 110 through the steam discharge port 310 and the steam inlet 111. The flow guiding member 120 is installed in the box body 110. A steam flow channel 121 is provided on the flow guiding member 120. One end of the steam flow channel 121 is communicated with the steam inlet 111. The steam in the cooking cavity can flow into the steam flow channel 121 from one end of the steam flow channel 121. Since the steam flow channel 121 is communicated with the liquid storage cavity 113, and the liquid storage cavity 113 stores coolant, the steam flowing into the steam flow channel 121 can exchange heat with the coolant, thereby reducing the temperature of the steam. The other end of the steam flow channel 121 is communicated with the steam outlet 112. The steam in the steam flow channel 121 that has been cooled by heat exchange can be discharged from the box body 110. Since the temperature of the steam discharged from the box body 110 is relatively low, users around the cooking appliance are not easily scalded by the steam, which is beneficial to improving the safety of users during the cooking process.

[0083] Figure 4 The arrow in the steam flow channel 121 is used to indicate the steam flow direction.

[0084] For the cooking appliances in the related art, the steam in the cooking cavity is directly discharged to the outside, which is likely to scald the users around the cooking appliances. The steam recovery device 100 in this embodiment can be used as an independent structure and installed on the cooking appliances in the related art that do not have a steam recovery structure, so that the cooking appliances in the related art have the steam recovery function. Without major modifications to the cooking appliances in the related art, cooking appliances with steam recovery function can be obtained, which is beneficial to reducing the processing difficulty of the cooking appliances.

[0085] The flow guide member 120 is located in the liquid storage cavity 113. The flow guide member 120 is used to guide the recovered steam so that the steam can flow along the flow guide member 120. Under the guiding action of the flow guide member 120, the steam exchanges heat with the coolant along a set route, and the steam after heat exchange can flow to the outside of the box body 110. The shape of the flow guide member 120 can be set according to the heat exchange requirements. By guiding the steam through the flow guide member 120, it is beneficial to improve the heat exchange effect between the steam and the coolant.

[0086] In some embodiments, optionally, the liquid storage cavity 113 is used to store water, and the steam flow channel 121 is connected to the liquid storage cavity 113. The steam flowing back into the steam flow channel 121 is used to contact and exchange heat with the coolant in the liquid storage cavity 113.

[0087] In this solution, it is defined that the steam flow channel 121 is connected to the liquid storage cavity 113, that is, an opening is provided at the bottom of the steam flow channel 121, and the steam flow channel 121 is connected to the liquid storage cavity 113 through the opening. After the steam flows into the steam flow channel 121, the steam in the steam flow channel 121 exchanges heat with the water in the liquid storage cavity 113. Since the steam flow channel 121 is connected to the liquid storage cavity 113, 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 equipment has a relatively low temperature.

[0088] In some embodiments, optionally, a part of the flow guide member 120 is immersed in the coolant.

[0089] The flow guide member 120 is provided with a steam flow channel 121. The flow guide member 120 is used to guide the recovered steam so that the steam can flow along the flow guide member 120. Under the guiding action of the flow guide member 120, 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 equipment.

[0090] A part of the flow guide member 120 is immersed in the water, so that the water can exchange heat with the flow guide member 120. In the case of steam flowing inside the steam, the steam can indirectly exchange heat with the water through the flow guide member 120.

[0091] Alternatively, an opening is provided at the bottom of the flow guide member 120, such that the steam flow channel 121 within the flow guide member 120 is in direct contact with water, thereby enabling direct heat exchange between the steam and the water. A part of the flow guide member 120 is immersed in water, and the water acts as a barrier to the steam, ensuring that the steam can only flow within the steam flow channel 121 and is not likely to flow out of the steam flow channel 121. That is, it can ensure that the steam can stably exchange heat with the water and can also ensure that the steam flow channel 121 can stably guide the steam.

[0092] Combined Figure 2 and Figure 5 As shown, in some embodiments, optionally, a highest liquid level line 114 is provided on the liquid storage cavity 113. Taking the bottom wall of the liquid storage cavity 113 as a reference plane, a part of the steam flow channel 121 is higher than the highest liquid level line 114.

[0093] A part of the steam flow channel 121 is higher than the highest liquid level line 114. Even when the liquid level in the liquid storage cavity 113 has reached the highest liquid level line 114, a part of the space within the steam flow channel 121 is still higher than the liquid level in the liquid storage cavity 113, and the space within the steam flow channel 121 that is higher than the liquid level is for the steam to flow.

[0094] When the user fills water into the liquid storage cavity 113, the water in the liquid storage cavity 113 usually does not exceed the highest liquid level line 114, and a part of the steam flow channel 121 is higher than the highest liquid level line 114. Therefore, it can be ensured that a part of the space within the steam flow channel 121 is not filled with water, thereby providing space for the steam to flow and ensuring that the steam can flow and exchange heat within the steam flow channel 121.

[0095] Combined Figure 2 and Figure 5 As shown, in some embodiments, optionally, a lowest liquid level line 115 is provided on the liquid storage cavity 113. Taking the bottom wall of the liquid storage cavity 113 as a reference plane, a part of the steam flow channel 121 is lower than the lowest liquid level line 115.

[0096] The lowest liquid level line 115 is provided on the liquid storage cavity 113, and the lowest liquid level line 115 serves as a reminder to the user. When the liquid level of the water in the liquid storage cavity 113 approaches the lowest liquid level line 115, the user needs to fill water into the liquid storage cavity 113 to avoid the problem of dry burning of the steam generating assembly.

[0097] A part of the steam flow channel 121 is below the lowest liquid level line 115. Even when the liquid level in the liquid storage cavity 113 is approaching the lowest liquid level line 115, a part of the water in the liquid storage cavity 113 is still above the bottommost part of the steam flow channel 121. The water blocks the steam, ensuring that the steam can only flow within the steam flow channel 121 and is not likely to flow out of the steam flow channel 121. 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 121 can stably guide the steam, improving the heat exchange effect of the steam and ensuring that the steam can be stably discharged from the cooking device, avoiding the accumulation of some recycled steam within the steam generating assembly.

[0098] In some embodiments, optionally, a steam flow channel 121 is formed by enclosing on the guiding member 120. Alternatively, a steam flow channel 121 is formed between the guiding member 120 and the inner wall of the liquid storage cavity 113.

[0099] The steam flow channel 121 can be independently formed on the guiding member 120, or a steam flow channel 121 is formed by enclosing between the guiding member 120 and the inner wall of the liquid storage cavity 113.

[0100] In some embodiments, optionally, one side of the guiding member 120 is connected to the top wall of the liquid storage cavity 113, and the other side of the guiding member 120 is connected to the bottom wall of the liquid storage cavity 113. Alternatively, one side of the guiding member 120 is connected to the top wall of the liquid storage cavity 113, and the other side of the guiding member 120 is spaced from the bottom wall of the liquid storage cavity 113.

[0101] The top of the guiding member 120 is connected to the inner wall of the liquid storage cavity 113, and the bottom of the guiding member 120 is also connected to the inner wall of the liquid storage cavity 113. The steam flowing into the box body 110 can only flow within the steam flow channel 121, avoiding the steam located within the box body 110 from flowing out of the steam flow channel 121, thereby ensuring that the steam can stably exchange heat with the coolant and ensuring that the steam will be discharged from the box body 110 only after heat exchange.

[0102] Certainly, it is also possible to set the top of the guiding member 120 to be connected to the inner wall of the liquid storage cavity 113, and the bottom of the guiding member 120 to be spaced from the inner wall of the liquid storage cavity 113. Since the liquid storage cavity 113 stores coolant, when the coolant covers the bottom of the guiding member 120, the coolant can block the steam within the steam flow channel 121, avoiding the steam located within the box body 110 from flowing out of the steam flow channel 121, thereby ensuring that the steam can stably exchange heat with the coolant and ensuring that the steam will be discharged from the box body 110 only after heat exchange.

[0103] Combined Figure 3 and Figure 4As shown, in some embodiments, optionally, the steam flow channel 121 is provided with at least one bent section, so that different parts of the steam flow channel 121 extend at least in two directions.

[0104] Forming a bent section on the steam flow channel 121 can extend the length of the steam flow channel 121, thereby increasing the flow duration of steam in the steam flow channel 121, increasing the heat exchange duration between steam and water, effectively reducing the temperature of the steam, and ensuring that the steam discharged from the cooking device is not likely to scald the user.

[0105] Combined Figure 3 and Figure 4 As shown, in some embodiments, optionally, the steam flow channel 121 includes a plurality of annular flow channels, and two adjacent annular flow channels are sleeved with each other, and the plurality of annular flow channels are sequentially communicated.

[0106] The plurality of annular flow channels are used to guide the steam. Two adjacent annular flow channels are communicated with each other, so that the steam can flow through the plurality of annular flow channels in sequence. The plurality of annular flow channels are in a sleeved relationship with each other, so that the plurality of annular flow channels can pass through most of the space inside the box body 110. When the steam flows into the annular flow channel, the steam can flow through most of the space inside the box body 110, which is beneficial to increasing the circulation duration of the steam in the steam flow channel 121, further extending the heat exchange duration between the steam and the coolant, improving the heat recovery effect, further reducing the temperature of the steam discharged from the cooking appliance, and ensuring the safety of the user during the use of the cooking appliance.

[0107] In a possible application, two adjacent annular flow channels are communicated through a communication port, and two adjacent communication ports are located on both sides in the length direction or both sides in the width direction of the box body 110.

[0108] The steam in the annular flow channel flows into the adjacent annular flow channel through the communication port. Two adjacent communication ports are located on both sides in the length direction or both sides in the width direction of the box body 110. Therefore, two adjacent communication ports are far away from each other, and the steam flowing into the annular flow channel needs to flow a long distance before flowing into the next annular flow channel, which is beneficial to extending the flow path of the steam.

[0109] Combined Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, optionally, the box body 110 includes: a water tank 116 and a cover body 117. The cover body 117 is detachably connected to the water tank 116. A liquid storage cavity 113 is provided between the cover body 117 and the water tank 116. The flow guiding member 120 is provided on the water tank 116 or the cover body 117.

[0110] The water tank 116 is used to store the coolant, and the cover body 117 is buckled at the opening position of the water tank 116. The cover body 117 can be detached from the water tank 116, so that the water tank 116 can be opened. After the steam recovery device 100 is used, the cover body 117 is detached from the water tank 116, and the user can clean the inside of the water tank 116 to avoid the growth of bacteria in the water tank 116, ensure that the steam passing through the steam recovery device 100 and discharged is not easily contaminated, and thus avoid the contamination of the cooking environment.

[0111] The flow guiding member 120 can be installed on the cover body 117. After the cover body 117 is detached, the flow guiding member 120 is detached from the water tank 116 together with the cover body 117, avoiding interference of the flow guiding member 120 with the cleaning process inside the water tank 116. Of course, the flow guiding member 120 can also be arranged on the water tank 116.

[0112] In a possible application, the cover body 117 can be locked to the water tank 116 by structures such as screws and buckles. To ensure the sealing performance between the cover body 117 and the water tank 116, a sealing member can be arranged between the cover body 117 and the water tank 116. For example, the sealing member can be a rubber pad, a silica gel pad, etc.

[0113] In some embodiments, optionally, the steam inlet 111 and the steam outlet 112 are arranged on the cover body 117. Or, the steam inlet 111 and the steam outlet 112 are arranged on the water tank 116. Or, one of the steam inlet 111 and the steam outlet 112 is arranged on the cover body 117, and the other is arranged on the water tank 116.

[0114] The steam inlet 111 and the steam outlet 112 can be arranged on the cover body 117 at the same time. The cover body 117 is located at the top of the water tank 116, and the coolant in the water tank 116 is not easily overflowed through the steam inlet 111 and the steam outlet 112.

[0115] Or, based on the relative positions between the steam recovery device 100 and the main body of the cooking appliance, the steam inlet 111 and the steam outlet 112 can be arranged on the water tank 116 at the same time according to the installation requirements.

[0116] Or, one of the steam inlet 111 and the steam outlet 112 can be arranged on the cover body 117, and the other can be arranged on the water tank 116.

[0117] In some embodiments, optionally, along the extension direction of the steam flow channel 121, the length of the steam flow channel 121 is greater than or equal to 1000 mm.

[0118] When the length of the steam flow channel 121 is limited to be greater than or equal to 1000 mm, the steam flow channel 121 has a relatively long length, and the flow time of steam in the steam flow channel 121 is relatively long, thereby prolonging the heat exchange time between steam and water, improving the heat recovery effect, further reducing the temperature of the steam discharged from the cooking device, and ensuring the safety of the user during the use of the cooking device.

[0119] In a possible application, the length of the steam flow channel 121 ≤ 1500 mm.

[0120] As Figure 4 shown, in some embodiments, optionally, the width W of the steam flow channel 121 satisfies W ≥ 5 mm.

[0121] The larger the width of the steam flow channel 121, the larger the heat exchange area between steam and the coolant. When the width of the steam flow channel 121 is limited to be greater than or equal to 5 mm, the steam flow channel 121 has a relatively large width, and the high-temperature steam can efficiently exchange heat with the coolant, improving the heat recovery effect, further reducing the temperature of the steam discharged from the box body 110, and ensuring the safety of the user during the use of the cooking appliance.

[0122] In a possible application, W ≤ 10 mm.

[0123] Combined with Figure 4 and Figure 7 shown, in some embodiments, optionally, the steam recovery device 100 further includes: a fan 150, the fan 150 is connected to the box body 110, and the fan 150 is used to pump the steam in the steam flow channel 121 towards the steam outlet 112.

[0124] When the fan 150 operates, the fan 150 is used to pump the steam in the steam flow channel 121 towards the steam outlet 112. Driven by the fan 150, the steam is discharged to the outside of the cooking device at a relatively high flow rate. Due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is relatively large, and the water molecules in the steam quickly mix with the air, making it difficult to form visible water droplets or condensed water. At the same time, the high-speed flow of the steam also reduces the possibility of water molecules aggregating in a certain place, thereby avoiding the formation of condensed water.

[0125] Combined with Figure 2 and Figure 6 shown, in some embodiments, optionally, the box body 110 is provided with an installation cavity 119, the steam flow channel 121 is provided with a flow channel outlet 118, the flow channel outlet 118 is communicated with the steam outlet 112 through the installation cavity 119, and the fan 150 is located in the installation cavity 119.

[0126] An installation cavity 119 is provided on the base 200. The blower 150 is installed in the installation cavity 119. The installation cavity 119 is used to connect the flow channel outlet 118 and the steam outlet 112. By arranging the blower 150 in the installation cavity 119, the air flow flowing into the installation cavity 119 basically comes from the flow channel outlet 118. It is not easy for the blower 150 to extract the air inside the base 200, so as to ensure that the steam in the steam flow channel 121 is discharged at a relatively high flow rate, and further avoid the steam discharged from the cooking device from forming condensate water.

[0127] Combined with Figure 2 、 Figure 5 and Figure 7 As shown, in some embodiments, optionally, an air supplement hole 160 is provided on the box body 110, and the air supplement hole 160 is communicated with the installation cavity 119.

[0128] An air supplement hole 160 is opened on the box body 110, and the air supplement hole 160 is communicated with the installation cavity 119. When the blower 150 is running, external gas can be supplemented into the installation cavity 119 through the air supplement hole 160.

[0129] After the steam discharged from the steam flow channel 121 and the external gas supplemented by the air supplement hole 160 are mixed, the mixed gas is discharged through the steam outlet 112. The purpose of setting the air supplement hole 160 is to increase the air flow rate, reduce the temperature of the discharged steam, and at the same time can reduce the negative pressure of the steam outlet 112, avoid the steam in the steam flow channel 121 from being discharged too fast, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0130] In some embodiments, optionally, the opening area of the air supplement hole 160 is greater than or equal to the opening area of the steam outlet 112.

[0131] When the blower 150 is running, the opening area of the air supplement hole 160 will affect the negative pressure near the steam outlet 112. When the opening area of the air supplement hole 160 is greater than or equal to the opening area of the steam outlet 112, the air supplement hole 160 can provide sufficient external air for the blower 150, effectively reduce the negative pressure of the steam outlet 112, avoid the steam in the steam flow channel 121 from being discharged too fast, and ensure that the high-temperature steam can effectively exchange heat with the coolant.

[0132] In some embodiments, optionally, the wind speed V at the air outlet of the blower 150 satisfies V≥1m / s.

[0133] In order to allow the steam in the steam flow channel 121 to be discharged at a high speed into the room-temperature atmosphere, due to the rapid flow and diffusion of the steam, the contact area between the steam and the surrounding air is 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, thus avoiding the formation of condensed water. To achieve the above effects, the wind speed at the air outlet of the fan 150 is not less than 1 m / s to meet the high-speed drive of the steam.

[0134] In some embodiments, optionally, the opening area S of the steam outlet 112 satisfies S≥50 mm 2 。

[0135] The opening area of the steam outlet 112 is greater than or equal to 50 mm 2 , ensuring that the steam can be discharged smoothly and preventing the steam from accumulating in the steam material.

[0136] Such as Figure 6 shown, in some embodiments, optionally, the steam recovery device 100 further includes: a filter screen 130, the filter screen 130 is connected to the flow guide member 120, and the filter screen 130 is located in the steam flow channel 121.

[0137] The steam can pass through the filter screen 130, but the filter screen 130 can reduce the flow rate of the steam in the steam flow channel 121, thereby prolonging the flow duration of the steam in the steam flow channel 121, and further increasing the heat exchange duration between the steam and water.

[0138] Such as Figure 1 shown, in some embodiments, optionally, the steam recovery device 100 further includes: a connecting pipe 140, the first end of the connecting pipe 140 is connected to the steam inlet 111, and the second end of the connecting pipe 140 is used to connect to the steam discharge port 310.

[0139] The connecting pipe 140 connects the steam discharge port 310 and the steam inlet 111, enabling the steam in the cooking cavity to flow into the box body 110 through the connecting pipe 140. By providing the connecting pipe 140 between the main body part of the cooking appliance and the box body 110, the flexibility of the installation position of the box body 110 can be improved. The box body 110 does not need to be closely attached to the steam discharge port 310 of the cooking cavity, which is beneficial to improving the space utilization rate of each component in the cooking appliance. In the above manner, the steam recovery device 100 can be arranged outside the main body part of the cooking appliance. When the steam recovery device 100 is not needed, the connecting pipe 140 can be disassembled, so that the steam recovery device 100 can be separated from the main body part of the cooking appliance, facilitating the use and storage of the cooking appliance.

[0140] In an embodiment of the present utility model, a cooking device is proposed, which includes the steam recovery device 100 as described in any of the above embodiments and can achieve the same technical effects, and will not be elaborated herein.

[0141] As Figure 1 shown, in some embodiments, optionally, the cooking device further includes: a base 200 and a steamer assembly 300. The steamer assembly 300 is disposed on the base 200, and the steam recovery device 100 is disposed outside the base 200.

[0142] The steam recovery device 100 is disposed outside the base 200. Therefore, the steam recovery device 100 can be independently disposed outside the base 200, which is convenient for installing the steam recovery device 100.

[0143] In some embodiments, optionally, the steamer assembly 300 includes: a steamer 320 disposed on the base 200; and a cover 330 covering the steamer 320 to form a closed space inside the cover 330 and the steamer 320.

[0144] Food ingredients can be placed inside the steamer 320. The space inside the cover 330 and the steamer 320 is a cooking cavity. When the cover 330 covers the inside of the steamer 320, the inside of the cover 330 and the steamer 320 is in a closed state, that is, no air holes for exhausting are provided on the cover 330, so that the gas inside the cooking cavity will not be discharged outward through the cover 330, thereby ensuring that the cooking device can recover the heat of the steam and reduce the temperature of the steam discharged outward.

[0145] In the present utility model, the term "a plurality of" refers to two or more, unless otherwise clearly defined. Terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "connection" 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 utility model can be understood according to specific circumstances.

[0146] In the description of this specification, the description of terms such as "one embodiment", "some embodiments", "specific embodiments", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0147] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
