Technical Field

[0001] The present invention belongs to the technical field of electrical appliances, and in particular relates to a cooking device. Background Art

[0002] At present, steam cooking equipment such as steam ovens and electric steamers are kitchen equipment that convert water into high-temperature steam through heating devices to cook food. They can effectively meet users' needs for cooking methods such as steaming and baking, and improve users' cooking convenience.

[0003] During the use of the steam cooking device, a large amount of steam is generated, and the generated steam usually needs to be discharged to the outside to maintain the pressure balance in the electric steamer inner tank to ensure cooking efficiency.

[0004] In related technologies, a steam exhaust device is usually arranged at the top of the machine door. The steam exhaust device has a condensation channel and a condensation device arranged in the condensation channel. The steam in the inner tank is discharged into the condensation channel and then condensed and cooled by the condensation device to reduce the steam discharge volume and lower the steam discharge temperature.

[0005] However, the steam exhaust device in the related art only relies on the pressure difference generated by the heat dissipation fan to exhaust steam, and its exhaust efficiency is low, resulting in the inability to exhaust steam in time and unable to meet the requirements of some cooking equipment.

[0006] In view of this, this application is filed. Summary of the Invention

[0016] an exhaust fan, which is arranged in the steam exhaust channel and is used to extract the steam from the cooking cavity;

[0017] Under the action of the exhaust fan, the steam in the cooking cavity enters the steam exhaust channel and the heat dissipation duct in sequence through the steam exhaust port, and is mixed with the air flow in the heat dissipation duct before being discharged from the box.

[0018] In the above solution, a steam exhaust channel is provided that connects to the steam outlet and the heat dissipation duct to discharge steam.

[0021] Under the action of the exhaust fan, the steam in the cooking cavity enters the steam exhaust channel through the steam exhaust port, is condensed by the condensation component when flowing through the condensation component, and then enters the heat dissipation duct, and is mixed with the air flow in the heat dissipation duct before being discharged from the box.

[0022] By providing a condensation component, a better condensation effect can be achieved, the temperature and humidity of the steam can be reduced, and burns and excessive humidity of the discharged gas can be avoided.

[0023] In some embodiments, the cooking apparatus comprises:

[0024] The on-off device is arranged at the steam exhaust port and is used to control the on-off between the steam exhaust channel and the cooking cavity.

[0025] In the above embodiment, after cooking is completed, the on-off device is opened to connect the cooking cavity to the steam exhaust passage, and the exhaust fan is used to exhaust the steam in the cooking cavity.

[0035] By setting up an inclined guide surface, the condensed water is ensured to flow to the lowest point and eventually flow back into the cavity, ensuring that there is no water accumulation in the steam exhaust duct and that the condensation effect does not cause a large amount of water vapor to enter the heat dissipation duct and then be blown into the room.

[0036] In some embodiments, the condensing unit further includes a heat sink disposed outside the steam exhaust device and adjacent to an outer wall of the steam exhaust device to exchange heat with the airflow within the steam exhaust passage.

[0065] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0066] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0067] Reference Figure 1-4 The cooking device 100 provided in the embodiment of the present application includes a box body 1 and an inner pot 2 arranged in the box body 1.

[0068] The housing 1 is a rectangular hollow shell structure and is configured to form the outer contour of the cooking device 100. The interior space of the housing 1 is used to provide an installation space for the inner pot 2.

[0069] The inner tank 2 is arranged in the box body 1, and a cooking cavity is formed in the inner tank 2. The cooking cavity can be used to perform high-temperature cooking on food, thereby realizing the functions of baking and roasting.

[0070] In some embodiments, an opening is provided on the front side of the inner pot 2. A door is provided on the front side of the housing 1. The door is opposite to the front opening of the inner pot 2 and is used to open and close the front opening of the inner pot 2, thereby enabling the door to open and close the cooking cavity in the inner pot 2.

[0071] In some embodiments, a handle 7 is provided on the front wall of the door, and the handle 7 protrudes from the front side of the door. The handle 7 facilitates the user to open the door.

[0072] In some embodiments, a heating device is provided in the door to create a high temperature environment in the cooking cavity of the inner pot 2, thereby enabling the cooking device 100 to perform the roasting and baking functions.

[0073] In some embodiments, the heating device can be disposed on the inner wall of the inner pot 2, such as the top of the cooking cavity. It should be noted that in other embodiments, the heating device can also be disposed on the back of the cooking cavity, or on other side walls of the cooking cavity.

[0074] In this application, the box body 1 is defined as having a top and a bottom in the height direction, and a front and a rear in the width direction. Figure 1 As shown, the direction indicated by the X-axis arrow is the front, and the direction indicated by the Y-axis arrow is the top.

[0075] Reference Figure 3-4Cooking apparatus 100 further includes a heat dissipation duct 3. This duct 3 is disposed within housing 1 and outside inner pot 2. Specifically, it can be disposed in the cavity between inner pot 2 and housing 1. The air inlet of the heat dissipation duct 3 communicates with inner pot 2, while the air outlet of the heat dissipation duct 3 communicates with the exterior of housing 1.

[0076] A heat dissipation fan 4 is provided within the heat dissipation duct 3. The heat dissipation fan 4 is configured to provide wind force toward the air outlet of the heat dissipation duct 3, thereby enabling the air inlet of the heat dissipation duct 3 to absorb heat from the cooking cavity. The heat in the cooking cavity is then discharged to the outside of the cabinet 1 through the heat dissipation duct 3, thereby achieving heat dissipation within the cabinet 1.

[0077] In some embodiments, the air outlet end of the heat dissipation duct 3 is located at the front side of the box body 1 , that is, the heat dissipation duct 3 exhausts air and dissipates heat from the front side of the box body 1 .

[0078] In some embodiments, the cooling duct 3 is located in the top area of ​​the cabinet 1, that is, in the area above the inner container 2. In this case, the air inlet of the cooling duct 3 is located on the back side of its air outlet, and the cooling duct 3 extends along the front-to-back direction of the cabinet 1. The air outlet of the cooling duct 3 is located above the cabinet door, so the cooling duct 3 does not affect the opening or closing of the cabinet door.

[0079] In some embodiments, the heat dissipation fan 4 is a cross-flow fan and is disposed at the air inlet end of the heat dissipation duct 3 so as to increase the wind force at the air inlet end of the heat dissipation duct 3 and improve the heat dissipation efficiency.

[0080] In some embodiments, a support plate is provided within the housing 1, spaced apart from the inner container 2. An air scoop is provided on the top surface of the support plate, and the scoop and the support plate enclose a heat dissipation duct 3. The rear end of the scoop serves as the air inlet of the heat dissipation duct 3, and a heat dissipation fan 4 is provided at the rear end of the scoop. The front end of the scoop faces the front of the housing 1 and serves as the air outlet of the heat dissipation duct 3.

[0081] In some embodiments, reference Figure 4 The width of the heat dissipation duct 3 gradually widens from the air inlet end toward the air outlet end. Specifically, the width of the air guide gradually widens from the back to the front of the housing 1, thereby gradually widening the width of the heat dissipation duct 3. This allows the air flowing through the heat dissipation duct 3 to remove more heat, thereby improving heat dissipation efficiency.

[0082] In some embodiments, reference Figure 3 The top of the inner pot 2 is provided with a vent, which is provided on the top surface of the cooking cavity, and the cooking cavity can be connected to the heat dissipation duct 3 through the vent. By providing the vent, the air pressure balance of the inner and outer cavities can be ensured during the cooking process.

[0083] Therefore, refer to Figure 3 The middle airflow indicates the direction. When cooling fan 4 is running, negative pressure is created within cooling duct 3. This allows air within the cooking cavity to enter cooling duct 3 through the vents and be exhausted outside housing 1, achieving heat dissipation within the cooking cavity. If the air within the cooking cavity contains oil smoke, the smoke can also enter cooling duct 3 through the vents, achieving exhaust from the cooking cavity.

[0084] A gap exists between the support plate and the inner pot 2. A vent pipe is provided between the top of the inner pot 2 and the support plate. The top of the vent pipe connects to the heat dissipation duct 3, while the bottom of the vent pipe connects directly to the vent opening, that is, the bottom of the vent pipe connects to the cooking cavity. Therefore, air and cooking fumes in the cooking cavity can enter the vent pipe through the vent hole 11 and then enter the heat dissipation duct 3 through the vent pipe.

[0085] After cooking, when the door 9 is opened to remove the ingredients, steam will rush towards you, which can easily burn your face. To solve this problem, this application proposes a steam exhaust device 5. After work is completed, the steam exhaust port 10 is opened by the on-off device 53. The steam in the cavity is quickly exhausted under the action of the exhaust fan 52, avoiding the steam gushing out after the door 9 is opened, which may cause burns. At the same time, a better condensation effect can be achieved.

[0086] In some embodiments, reference Figure 4 The cooking device 100 includes a steam outlet 10. The steam outlet 10 is formed on the inner pot 2. The steam outlet 10 is used to discharge steam.

[0087] In some embodiments, reference Figure 5-11 The cooking device 100 includes a steam exhaust device 5. The steam exhaust device 5 is installed between the inner pot 2 and the box body 1. It is used to exhaust the steam in the cooking cavity through the steam exhaust port 10.

[0088] In some embodiments, the steam exhaust device 5 is installed on the top of the inner pot 2. Installing the steam exhaust device 5 on the top facilitates the exhaust of steam.

[0089] In some embodiments, the steam exhaust device 5 includes a steam exhaust channel 51. One end of the steam exhaust channel 51 is connected to the steam exhaust port 10. The other end of the steam exhaust channel 51 is connected to the heat dissipation duct 3.

[0090] In some embodiments, the steam exhaust device 5 includes an exhaust fan 52 . Exhaust fan 52 is installed within the steam exhaust passage 51 and is used to extract steam from the cooking chamber. The provision of an additional power component, primarily exhaust fan 52 , ensures rapid steam exhaust before the user opens the door 9, preventing burns caused by escaping steam.

[0091] In some embodiments, the exhaust fan 52 is configured as a centrifugal fan. Under the action of the centrifugal fan, the steam in the cooking cavity is quickly emptied. Of course, in some embodiments, the exhaust fan 52 can be configured as other types of fans according to different needs and overall structures.

[0092] In some embodiments, the steam exhaust passage 51 includes a first air duct and a volute connecting the steam exhaust port 10 and the air inlet end of the exhaust fan 52. The exhaust fan 52 is installed in the volute. One end of the volute is connected to the first air duct, and the other end of the volute is connected to the hot air duct.

[0093] Under the action of the exhaust fan 52, the steam in the cooking chamber passes through the steam outlet 10 and enters the steam exhaust channel 51 and the heat dissipation duct 3 in sequence. After mixing with the airflow in the heat dissipation duct 3, it is discharged from the cooking chamber. This allows the steam in the cooking chamber to be quickly exhausted before opening the door after cooking, preventing burns when the user opens the door.

[0094] In some embodiments, the steam exhaust device 5 includes a condensing component installed in the steam exhaust channel 51 for cooling the steam entering the steam exhaust channel 51 .

[0095] In some embodiments, the condensing component is installed outside the steam exhaust channel 51. By installing it outside, the heat dissipation fan 4 can be used to reduce the temperature of the condensing component.

[0096] In some embodiments, the condensation component is installed inside the steam discharge channel 51 and outside the steam discharge channel 51. The multiple configurations can improve the condensation effect of the steam.

[0097] By adding a condensing component to the steam exhaust device 5, the steam is condensed and collected during the exhaust process, thereby reducing the water vapor content in the exhausted steam and ensuring that the external space of the cooking device 100 is dry.

[0098] Reference Figure 6 Under the action of the exhaust fan 52, the steam in the cooking cavity enters the steam exhaust channel 51 through the steam exhaust port 10, is condensed by the condensation component when flowing through the condensation component, and enters the heat dissipation duct 3, and is mixed with the air flow in the heat dissipation duct 3 before being discharged from the box 1.

[0099] In the above solution, a steam exhaust channel 51 is provided, connected to the steam outlet 10 and the heat dissipation duct 3, to discharge steam after cooking. An exhaust fan 52 is provided to provide power for the steam flow, enabling rapid exhaust of steam from the cooking chamber, preventing steam from gushing out after the door 9 is opened, which could cause burns. The aforementioned condensation component can also achieve good condensation results.

[0100] After the condensed air enters the heat dissipation duct 3, on the one hand, it can be blown toward the heat dissipation duct 3 by the exhaust fan 52, and on the other hand, under the action of the heat dissipation fan 4, it is discharged faster and in a forward direction, achieving a better effect.

[0101] In some embodiments, the cooking device 100 includes a switching device 53 , which is provided at the steam exhaust port 10 and is used to control the connection between the steam exhaust channel 51 and the cooking cavity.

[0102] In the above embodiment, after cooking is completed, the on-off device 53 is opened to connect the cooking cavity with the steam exhaust passage 51, and the steam in the cooking cavity is exhausted by the exhaust fan 52. When steam exhaust is no longer necessary, the on-off device 53 is closed to maintain the sealing of the cooking cavity and ensure cooking efficiency.

[0103] In some embodiments, the on / off device 53 can be opened as needed during cooking to release steam. This allows for rapid reduction of humidity during cooking for moisture-sensitive ingredients, such as air frying, which requires a high humidity level, to achieve the desired cooking effect.

[0104] In some embodiments, the on-off device 53 further includes an exhaust component 5323 , which is movably mounted at the steam exhaust port 10 to control the opening and closing of the steam exhaust port 10 .

[0105] In some embodiments, the on-off device 53 further includes a driving component 532, one end of which is fixedly mounted on the outside of the steam exhaust device 5. The other end of the driving component 532 extends into the steam exhaust channel 51 and is connected to the exhaust component 5323;

[0106] The driving component 532 drives the exhaust component 5323 to open the steam exhaust port 10 so that the cooking cavity is connected to the steam exhaust device 5.

[0107] In the above, by setting the driving component 532 to drive the exhaust component 5323 to operate, the exhaust is automated and the steam is discharged in a timely manner. By controlling the operating state of the driving component 532, the on / off state of the steam exhaust port 10 can be controlled, and the on / off control can be achieved according to different usage scenarios.

[0108] Reference Figure 7 The driving component 532 includes a driving motor 5321 and a driving rod 5322. One end of the driving rod 5322 is connected to the driving end of the driving motor 5321. The other end of the driving rod 5322 is connected to the exhaust component 5323 to drive the exhaust component 5323 to open or close the steam exhaust port 10.

[0109] In some embodiments, the on-off device 53 comprises an electromagnetic lock that opens or closes the steam outlet 10 .

[0110] In some embodiments, the cooking device 100 further includes a seal 533 disposed between the exhaust component 5323 and the steam exhaust port to ensure the sealing of the cooking cavity and reduce heat loss during the cooking process. Figure 7 The seal 533 is wrapped around the exhaust component 5323, mainly sealing the steam exhaust channel 51 to ensure that steam does not overflow from here when closed.

[0111] In some embodiments, the seal 533 may also be provided at the steam outlet 10. When the exhaust component 5323 is used to close the steam outlet 10, the exhaust component 5323 and the seal 533 are in close contact to prevent the cavity from leaking air from the steam outlet 10.

[0112] In some embodiments, reference Figure 9-10 A condensation chamber 551 is formed in the steam discharge channel 51. The cooling element 541 is arranged in the condensation chamber 551. The condensation chamber 551 is provided to cool the steam and reduce the humidity of the gas output outside the box body 1.

[0113] In some embodiments, reference Figure 9-10 The condensation component includes a cooling member 541 disposed in the steam discharge channel 51, and the cooling member 541 is disposed opposite to the steam discharge port 10. In some embodiments, the cooling member 541 is installed in the condensation chamber 551 to reduce the steam temperature.

[0114] By providing the cooling element 541, steam can be condensed and collected during the steam exhaust process, thereby reducing the water vapor content of the exhaust steam and ensuring that the kitchen space is dry.

[0115] In some embodiments, reference Figure 10-11 The condensation chamber 551 further includes a guide surface 542, which is arranged opposite to the air inlet of the exhaust fan 52. The guide surface 542 is arranged as an inclined surface inclined toward the inner pot 2 to guide the condensed water into the cooking chamber. Figure 11 In the figure, the blue line is a schematic horizontal line to represent the inclined feature of the guide surface 542.

[0116] By setting the inclined guide surface 542, it is ensured that the condensed water flows to the lowest point and eventually flows back to the cavity, ensuring that there is no water accumulation in the steam exhaust duct and ensuring that the condensation effect does not cause a large amount of water vapor to enter the heat dissipation duct 3 and then blow into the room.

[0117] Reference Figure 11The design details of the condensation chamber 551 are all inclined from different angles to ensure that the condensed water flows to the lowest point and eventually flows back to the cavity, ensuring that there is no water accumulation in the condensation chamber 551 and that the condensation effect does not cause a large amount of water vapor to enter the heat dissipation duct 3 and then be blown into the room.

[0118] In some embodiments, to achieve a better condensation effect and reduce the discharge of steam, the condensation component further includes a heat sink 543, which is disposed outside the steam discharge device 5 and close to the outer wall of the steam discharge device 5 to exchange heat with the airflow in the steam discharge channel 51. The heat sink 543 can quickly absorb the heat in the steam discharge channel 51 and contribute to the cooling of the gas in the channel.

[0119] In some embodiments, the cooling element 541 is configured as a phase change material, which is installed in the condensation chamber 551. In addition to the metal plate absorbing steam in the related condensation scheme, the phase change heat absorption of the phase change material is added to absorb the heat of the steam.

[0120] In some embodiments, reference Figure 8 The heat sink 543 is configured as a heat sink, which is arranged and mounted on the outer wall of the condensing chamber 551. The heat sinks absorb heat from the phase change material, allowing it to cool quickly, thereby absorbing more steam heat and improving the utilization efficiency of the phase change material. Furthermore, they quickly absorb heat from the condensing chamber 551, accelerating the cooling of the condensing chamber 551.

[0121] In some embodiments, the heat sink is disposed on one side of the heat dissipation fan 4 , and the heat dissipation fan 4 absorbs heat from the surrounding area and can cool the heat sink to achieve a better heat dissipation effect.

[0122] Through the multiple effects of phase change materials and heat sinks, better heat dissipation effect is achieved.

[0123] In some embodiments, the phase change material can be provided as a heat dissipation layer and mounted on the inner wall of the condensation chamber 551. In some embodiments, the heat dissipation layer can be provided opposite to the steam outlet 10 to improve contact efficiency.

[0124] In some embodiments, the cooking device 100 may not be provided with the on-off device 53 at the steam outlet 10, and a solution for rapid exhaust of steam from the cooking cavity may also be implemented. Of course, a solution for condensing steam may also be implemented.

[0125] In some embodiments, the cooking device 100 may not be provided with the exhaust fan 52. In this case, although the steam exhaust speed is reduced, the condensation function during the steam exhaust process can still be achieved normally.

[0126] In some embodiments, the cooking device 100 is not equipped with the exhaust fan 52 and the on-off device 53 to implement a condensation solution during the steam exhaust process.

[0127] In some embodiments, the cooking device 100 further includes a steam device (not shown), which is detachably disposed between the housing 1 and the inner pot 2. The steam device includes a water storage cavity, and an outer wall of the steam device includes a steam hole connecting the water storage cavity and the cooking cavity.

[0128] The water in the accommodating cavity can evaporate to form steam, and the formed steam can enter the cooking cavity through the steam holes.

[0129] In some embodiments, the cooking device further includes a humidity detection device located within the cooking cavity for detecting humidity within the cooking cavity and transmitting the humidity value to a controller. The humidity value detected by the humidity detection device can be used to vent steam at desired points depending on the cooking ingredients. For example, for humidity-sensitive ingredients, if excessive humidity is detected during cooking, the steam vent 10 can be opened to meet cooking needs.

[0130] A control logic of the cooking device 100 is described below.

[0131] Start cooking, and during the cooking process, the steam outlet 10 is automatically opened or closed according to the cooking requirements of the ingredients to control the amount of steam in the cooking cavity. In other words, the humidity in the cooking cavity is controlled to meet the moisture requirements for cooking the ingredients.

[0132] After finishing cooking, the driving component 532 is controlled to open the steam outlet 10 to quickly discharge the condensed air. Then the door is opened to take out the food.

[0133] In some embodiments, after exhaust is completed and the humidity in the cooking chamber reaches a certain level, the user can be notified to open the door to take out the food. In some embodiments, the door can be opened after a certain period of time after cooking to prevent burns.

[0134] This application also proposes a solution for recovering condensed water condensed from steam.

[0135] Reference Figure 12-17 In some embodiments, the steam exhaust device 5 includes a steam exhaust channel 51 , one end of which is connected to the steam exhaust port 10 .

[0136] In some embodiments, the condensation chamber 551 is connected to a side of the steam exhaust channel 51 away from the steam exhaust port 10 , and is used to cool the steam entering the condensation chamber 551 .

[0137] In some embodiments, the steam exhaust device 5 further includes a condensation chamber 551. The condensation chamber 551 is connected to the air outlet of the exhaust fan 52 to receive steam from the cooking chamber and cool the steam entering the condensation chamber 551. In some embodiments, the condensation chamber 551 has an opening that is connected to the air outlet end of the steam exhaust channel 51 to receive the extracted steam.

[0138] In some embodiments, the steam exhaust device 5 further includes a condensed water outlet 552 , which is used to connect the condensation cavity 551 and the cooking cavity to allow the condensed water to flow into the cooking cavity.

[0139] In the above embodiment, by setting a condensation chamber 551 at the air outlet end of the steam exhaust channel 51, the steam exhaust channel 51 is opened when the humidity in the cooking chamber is high to discharge and condense moisture, and condensed water can be recovered without blowing moisture into the room, and the condensed water is also better treated.

[0140] The steam exhaust device 5 further includes an exhaust fan 52. The exhaust fan 52 is installed in the steam exhaust channel 51. It is used to extract the steam in the cooking cavity.

[0141] Under the action of the exhaust fan 52 , the steam in the cooking cavity passes through the steam outlet 10 and the steam outlet channel 51 and enters the condensation cavity 551 to be condensed.

[0142] In the above embodiment, the exhaust fan 52 is provided to provide power for the steam flow, thereby realizing rapid exhaustion of the steam in the cooking cavity.

[0143] In some embodiments, the cooking device further includes a condensed water discharge pipe 553. The condensed water discharge pipe 553 is used to connect the condensation chamber and the inner pot.

[0144] In some embodiments, the steam exhaust passage 51 includes a volute for mounting an exhaust fan 52, a second air duct connecting the volute's air inlet and the steam exhaust port 10, and a third air duct connecting the volute's air outlet and the condensation chamber 551. Under the action of the exhaust fan 52, steam passes through the steam exhaust port 10, the second air duct, the volute, and the third air duct before entering the condensation chamber 551.

[0145] In some embodiments, steam exhaust passage 51 includes a volute for mounting exhaust fan 52 and a second air duct connecting the volute's air inlet and steam exhaust port 10. The volute's air outlet is connected to condensation chamber 551. Under the action of exhaust fan 52, steam passes through steam exhaust port 10, the second air duct, and the volute before entering condensation chamber 551.

[0146] In some embodiments, steam exhaust passage 51 includes a volute for mounting exhaust fan 52 and a third air duct connecting the volute's air outlet and condensation chamber 551. The volute's air inlet communicates with steam exhaust port 10. Under the influence of exhaust fan 52, steam passes through steam exhaust port 10, the volute, and the third air duct before entering condensation chamber 551.

[0147] In some embodiments, steam exhaust passage 51 includes a volute housing an exhaust fan 52. The volute is installed between housing 1 and inner pot 2. The air inlet of the volute is connected to steam outlet 10, and the air outlet of the volute is connected to condensation chamber 551. Under the action of exhaust fan 52, steam flows through the volute and is discharged from the cooking chamber.

[0148] In the above embodiment, exhaust fan 52 is provided to power the steam flow, enabling rapid exhaust of the steam from the cooking chamber. Intelligent on / off control device 53 opens steam exhaust channel 51 when humidity in the cooking chamber is high, allowing moisture to be discharged and condensed. This also allows for condensate recovery, preventing moisture from being blown indoors and effectively treating the condensed water.

[0149] In some embodiments, the condensation chamber includes a channel body, one end of the channel body is connected to the side of the steam exhaust channel 51 away from the steam exhaust port 10, the other end of the channel body is closed, and the condensation water outlet 552 is set on the side wall of the channel body close to the inner tank.

[0150] One end of the channel body receives steam from the cooking cavity and cools it, and then discharges condensed water out of the channel body, thereby realizing the recovery of condensed water.

[0151] In some embodiments, the steam exhaust device 5 includes a condensing component, which is disposed in the condensing chamber and is used to condense the steam in the condensing chamber to improve the condensation efficiency in the condensing chamber.

[0152] In some embodiments, the condensing component includes a cooling member 541. The cooling member is disposed in the condensing chamber and is used to absorb heat from the steam to cool the steam entering the condensing chamber, thereby reducing the temperature of the steam.

[0153] By providing the cooling element 541, steam can be condensed and collected during the steam exhaust process, thereby reducing the water vapor content of the exhaust steam and ensuring that the kitchen space is dry.

[0154] In some embodiments, to achieve a better condensation effect and reduce the discharge of steam, the condensation component further includes a heat sink 543, which is disposed outside the condensation chamber 551 and close to the outer wall of the condensation chamber 551 to exchange heat with the airflow within the condensation chamber 551. The heat sink 543 can quickly absorb the heat within the condensation chamber 551 and cool the gas within the condensation chamber 551.

[0155] In some embodiments, the cooling element 541 is configured as a phase change material, which is installed in the condensation chamber 551. In addition to the metal plate absorbing steam in the related condensation scheme, the phase change heat absorption of the phase change material is added to absorb the heat of the steam.

[0156] In some embodiments, heat dissipation element 543 is configured as a heat sink, which is arranged and mounted on the outer wall of condensation chamber 551. The heat sinks absorb heat from the phase change material, allowing it to cool rapidly, thereby absorbing more steam heat and improving the utilization efficiency of the phase change material. Furthermore, they quickly absorb heat from condensation chamber 551, accelerating the cooling of condensation chamber 551.

[0157] In some embodiments, the phase change material can be provided as a heat dissipation layer and mounted on the inner wall of the condensation chamber 551. In some embodiments, the heat dissipation layer can be spread flat in the condensation chamber 551 to improve contact efficiency.

[0158] In some embodiments, the steam exhaust device 5 further includes a condensation channel 554, which is disposed outside the condensation chamber 551. This reduces the heat exchange between the condensation chamber 551 and the inner container 2, thereby affecting the condensation effect.

[0159] The steam exhaust channel 51 is designed at the top to facilitate the exhaust of steam. The exhaust fan 52 directly works on the steam in the cooking cavity, thereby achieving a rapid exhaust effect.

[0160] In the condensed water recovery solution, the steam outlet 10 can still be equipped with an on / off device 53 to control whether steam is discharged from the cooking chamber. The on / off device 53 is the same as in the above solution and will not be described in detail here. The on / off device 53 can control the passageway, opening it when needed and closing it when not.

[0161] In this embodiment, the steam exhaust device 5 is disposed between the inner pot 2 and the housing 1. A condensation chamber 551 is connected to the side of the steam exhaust channel 51 away from the steam outlet 10 to receive and cool steam from the cooking chamber. Condensate is then transferred from the condensation chamber 551 to the cooking chamber via the condensate outlet 552. This allows for condensate recovery, preventing moisture from being blown into the room. The condensate is also better processed and effectively controlled to meet the humidity requirements of different ingredients.

[0162] The term "connectivity" as used in this application refers to the spatial positional relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path and / or be transported to the second part. The first part and the second part may be directly connected, or the first part and the second part may be indirectly connected through at least one third party, and the third party may be a fluid channel such as a pipe, channel, conduit, guide member, hole, groove, etc., or a chamber allowing fluid to flow through, or a combination of the above.
