Description

Technical Field

[0001] This invention belongs to the field of electrical appliance technology, and in particular relates to a cooking device. Background Technology

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

[0003] During the use of steam cooking equipment, 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 inner pot of the electric steamer to ensure cooking efficiency.

[0004] In related technologies, an exhaust channel with an exhaust fan is generally provided above the inner liner, and the remaining gas is discharged through the exhaust channel under the drive of the exhaust fan.

[0005] If the residual steam in the inner pot is directly discharged through the exhaust duct after cooking, a large amount of condensation will form at the exhaust vent. The condensation will flow onto the surface of the machine, seriously affecting the user experience.

[0006] In view of the above, this application is hereby submitted. Summary of the Invention

[0007] This application utilizes a steam exhaust device installed between the inner liner and the outer casing. The condensation chamber is connected to the steam exhaust channel on the side furthest from the steam outlet to receive and cool steam from the cooking chamber. Cooled water flows from the condensation chamber back into the cooking chamber through the condensate outlet. This achieves condensate recovery, preventing moisture from being blown into the room. The condensate is also effectively treated, and humidity is effectively controlled to meet the different humidity requirements of various foods.

[0008] This application embodiment includes a cooking device, comprising:

[0019] The condensate outlet connects the condensate chamber and the inner liner to allow condensate to flow from the condensate chamber into the cooking chamber.

[0020] In the above embodiments, by setting a condensation chamber at the air outlet of the steam exhaust channel, the steam exhaust channel is opened to discharge and condense moisture when the humidity in the cooking cavity is high, and condensate water can be recovered, preventing moisture from being blown into the room, and the condensate water is also treated well.

[0021] In some embodiments, the steam exhaust device includes:

[0022] An exhaust fan, located in the steam exhaust channel, is used to remove steam from the cooking cavity;

[0023] Steam in the cooking chamber is condensed in the condensing chamber by the action of the exhaust fan, passing through the steam outlet and steam discharge channel.

[0024] In the above embodiments, by setting an exhaust fan, power is provided for the steam flow, thereby enabling the rapid emptying of steam from the cooking cavity.

[0025] In some embodiments, the cooking device includes:

[0026] An on / off device, located at the steam outlet, is used to control the connection between the steam exhaust channel and the cooking chamber.

[0027] In the above embodiments, after cooking is completed, the on / off device is opened to connect the cooking chamber with the steam exhaust channel, and the steam in the cooking chamber is discharged under the action of the exhaust fan. Simultaneously, when steam discharge is not required, the on / off device is closed to maintain the sealing of the cooking chamber and ensure cooking efficiency.

[0028] In some embodiments, the switching device further includes:

[0029] An exhaust component, which is movably installed at the steam exhaust outlet to control the opening and closing of the steam exhaust outlet;

[0030] A drive component, one end of which is fixedly mounted on the outside of the steam exhaust device. The other end of the drive component extends into the steam exhaust passage and connects to the exhaust component;

[0031] The drive component drives the exhaust component to open the steam outlet so that the cooking chamber is connected to the steam exhaust device.

[0032] By setting up a drive component to drive the exhaust component, the exhaust process is automated, and steam is discharged in a timely manner.

[0033] In some embodiments, a seal is also included, disposed between the exhaust component and the steam exhaust port, to ensure the sealing of the cooking cavity and reduce heat loss during cooking.

[0036] In some embodiments, the steam discharge device includes a condensing component disposed within a condensing chamber for condensing the steam within the condensing chamber, thereby improving the condensation efficiency within the condensing chamber.

[0037] In some embodiments, the condensing component includes a cooling element disposed within the condensing chamber, the cooling element being used to absorb heat from the steam to cool the steam entering the condensing chamber.

[0038] By installing cooling components, steam can be condensed and collected during the exhaust process, reducing the water content of the exhaust steam and ensuring the kitchen space remains dry.

[0039] In some embodiments, the condensing component further includes a heat dissipation element disposed outside the steam exhaust device and close to the outer wall of the steam exhaust device to exchange heat with the airflow in the steam exhaust channel. The heat dissipation element can quickly absorb heat from the steam exhaust channel and cool the gas in the channel.

[0068] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0069] In the description of this invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0070] Reference Figure 1-4 The cooking device 100 provided in this embodiment includes a housing 1 and an inner pot 2 disposed inside the housing 1.

[0071] The housing 1 has a rectangular hollow shell structure. The housing 1 is configured to form the external outline of the cooking device 100. The internal space of the housing 1 is used to provide installation space for the inner liner 2.

[0072] The inner liner 2 is located inside the cabinet 1, and a cooking cavity is formed inside the inner liner 2. This cooking cavity can be used for high-temperature cooking of food, thus realizing the functions of baking and roasting.

[0073] In some embodiments, the inner liner 2 has an opening on its front side. The cabinet 1 has a door on its front side. The door is opposite to the opening on the front side of the inner liner 2 and is used to open and close the opening on the front side of the inner liner 2, thereby allowing the door to open and close the cooking cavity in the inner liner 2.

[0074] In some embodiments, a handle 7 is provided on the front side wall of the cabinet door, and the handle 7 protrudes from the front side of the cabinet door. The handle 7 makes it easier for the user to open the cabinet door.

[0075] In some embodiments, a heating device is provided inside the door. The heating device is used to create a high-temperature environment inside the cooking cavity of the inner pot 2, thereby enabling the cooking equipment 100 to perform baking and roasting functions.

[0076] In some embodiments, the heating device may 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 some other embodiments, the heating device may also be disposed on the back of the cooking cavity, or on other side walls of the cooking cavity.

[0077] In this application, the housing 1 is defined to have a top and a bottom in the height direction, and a front and a rear in the width direction. (See reference...) Figure 1 As shown, the X-axis arrow points to the front, and the Y-axis arrow points to the top.

[0078] Reference Figure 3-4The cooking appliance 100 also includes a heat dissipation duct 3. The heat dissipation duct 3 is located inside the cabinet 1 and outside the inner liner 2. Specifically, the heat dissipation duct 3 can be located in the cavity between the inner liner 2 and the cabinet 1. The air inlet of the heat dissipation duct 3 is connected to the inner liner 2, and the air outlet of the heat dissipation duct 3 is connected to the outside of the cabinet 1.

[0079] A cooling fan 4 is installed inside the cooling duct 3. The cooling fan 4 is used to provide airflow to the air outlet of the cooling duct 3, so that the air inlet of the cooling duct 3 can absorb the heat from the cooking cavity, and then discharge the heat from the cooking cavity to the outside of the cabinet 1 through the cooling duct 3, thereby realizing the heat dissipation function of the cabinet 1.

[0080] In some embodiments, the air outlet of the heat dissipation duct 3 is located on the front side of the housing 1, that is, the heat dissipation duct 3 exhausts air from the front side of the housing 1 to dissipate heat.

[0081] In some embodiments, the heat dissipation duct 3 is located in the top region of the housing 1, that is, in the region above the inner liner 2. In this case, the air inlet of the heat dissipation duct 3 is located on the back side of its air outlet, and the heat dissipation duct 3 extends along the front-rear direction of the housing 1. The air outlet of the heat dissipation duct 3 is located on the upper side of the door, so the heat dissipation duct 3 will not affect the opening or closing of the door.

[0082] In some embodiments, the cooling fan 4 is a cross-flow fan and is located at the air inlet of the cooling duct 3 to increase the airflow at the air inlet of the cooling duct 3 and improve the cooling efficiency.

[0083] In some embodiments, the housing 1 is provided with support plates, which are spaced apart above the inner liner 2. A guide hood is provided on the top surface of the support plates, and the guide hood and the support plates enclose a heat dissipation duct 3. In this case, the rear end of the guide hood serves as the air inlet of the heat dissipation duct 3, and the cooling fan 4 is located at the rear end of the guide hood. The front end of the guide hood faces the front of the housing 1 and serves as the air outlet of the heat dissipation duct 3.

[0084] In some embodiments, refer to Figure 4 In the direction from the air inlet to the air outlet of the heat dissipation duct 3, the width of the heat dissipation duct 3 gradually increases. Specifically, in the direction from back to front of the housing 1, the width of the air guide shroud gradually increases, thereby allowing the width of the heat dissipation duct 3 to gradually increase, so that the air flowing through the heat dissipation duct 3 can carry away more heat and improve heat dissipation efficiency.

[0085] In some embodiments, refer to Figure 3 The inner pot 2 has a vent at its top, which is located on the top surface of the cooking cavity. The cooking cavity can be connected to the heat dissipation duct 3 through the vent. The vent ensures the air pressure balance between the inner and outer cavities during cooking.

[0086] Therefore, refer to Figure 3 The airflow indicator points to the direction of airflow. When the cooling fan 4 is running, a negative pressure is created inside the cooling duct 3, allowing air from the cooking cavity to enter the cooling duct 3 through the vent and then be exhausted to the outside of the cabinet 1, thus achieving the cooling function of the cooking cavity. When the air inside the cooking cavity contains oil fumes, the fumes can also enter the cooling duct 3 through the vent, achieving the smoke extraction function of the cooking cavity.

[0087] There is a gap between the support plate and the inner pot 2, and a vent pipe is provided between the top of the inner pot 2 and the support plate. The top end of the vent pipe is connected to the heat dissipation duct 3, and the bottom end of the vent pipe is directly connected to the vent, that is, the bottom end of the vent pipe is connected to the cooking cavity. Therefore, air and 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.

[0088] After cooking, when opening door 9 to remove ingredients, steam will rush out and easily burn the face. To solve this problem, this application proposes a steam exhaust device 5. After the work is completed, the steam exhaust port 10 is opened by the on / off device 53, and the steam in the cavity is quickly vented by the exhaust fan 52, preventing steam from rushing out after door 9 is opened and causing burns. At the same time, it can achieve a better condensation effect.

[0089] In some embodiments, refer to Figure 4 The cooking appliance 100 includes a steam vent 10. The steam vent 10 is formed on the inner pot 2. The steam vent 10 is used to discharge steam.

[0090] In some embodiments, refer to Figure 5-11 The cooking appliance 100 includes a steam exhaust device 5. The steam exhaust device 5 is installed between the inner liner 2 and the housing 1. It is used to exhaust steam from the cooking chamber through the steam exhaust port 10.

[0091] In some embodiments, the steam exhaust device 5 is installed on the top of the inner liner 2, which facilitates the exhaust of steam.

[0092] In some embodiments, the steam exhaust device 5 includes a steam exhaust passage 51. One end of the steam exhaust passage 51 is connected to a steam outlet 10. The other end of the steam exhaust passage 51 is connected to a heat dissipation duct 3.

[0093] In some embodiments, the steam exhaust device 5 includes an exhaust fan 52. The exhaust fan 52 is installed inside the steam exhaust channel 51. It is used to extract steam from the cooking cavity. By providing an additional power component, mainly referring to the exhaust fan 52, it is ensured that steam can be discharged quickly before the user opens the door 9, preventing the user from being scalded by the gushing steam.

[0094] In some embodiments, the exhaust fan 52 is configured as a centrifugal fan. The centrifugal fan rapidly vents the steam from the cooking chamber. Of course, in some embodiments, the exhaust fan 52 can be configured as other types of fans depending on different needs and the overall structure.

[0095] In some embodiments, the steam exhaust passage 51 includes a first air duct connecting the steam exhaust outlet 10 and the air inlet of the exhaust fan 52, and a volute. The exhaust fan 52 is installed inside 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.

[0096] Steam in the cooking chamber, under the action of the exhaust fan 52, enters the steam exhaust channel 51 and the heat dissipation duct 3 sequentially through the steam exhaust port 10, and mixes with the airflow in the heat dissipation duct 3 before being discharged from the cabinet. This allows for the rapid discharge of steam from the cooking chamber before opening the door after cooking, preventing users from being scalded when opening the door.

[0097] In some embodiments, the steam discharge device 5 includes a condensing component. The condensing component is installed within the steam discharge passage 51 and is used to cool the steam entering the steam discharge passage 51.

[0098] In some embodiments, the condenser is mounted externally near the steam exhaust passage 51. By mounting it externally, the temperature of the condenser can be reduced using the cooling fan 4.

[0099] In some embodiments, the condensing component is installed both inside and outside the steam discharge passage 51. This multiple arrangement can improve the condensation effect of the steam.

[0100] By adding a condensing component to the steam exhaust device 5, the steam is condensed and collected during the exhaust process, reducing the water content in the exhaust steam and ensuring the dryness of the external space of the cooking equipment 100.

[0101] Reference Figure 6 Steam in the cooking chamber is condensed by the exhaust fan 52 and enters the steam exhaust channel 51 through the steam exhaust port 10. After passing through the condensing component, it enters the heat dissipation duct 3 and mixes with the airflow in the heat dissipation duct 3 before being discharged from the housing 1.

[0102] In the above scheme, a steam exhaust channel 51 is connected to a steam exhaust outlet 10 and a heat dissipation duct 3 to discharge steam after cooking. An exhaust fan 52 provides power for the steam flow, enabling rapid emptying of steam from the cooking cavity and preventing steam from escaping and causing burns when the door 9 is opened. The aforementioned condenser component also achieves good condensation performance.

[0103] After the condensed air enters the heat dissipation duct 3, it can be blown towards the heat dissipation duct 3 by the exhaust fan 52, and under the action of the heat dissipation fan 4, it is discharged faster and in a forward direction, achieving a better effect.

[0104] In some embodiments, the cooking appliance 100 includes an on / off device 53 located at the steam outlet 10 for controlling the connection or disconnection between the steam outlet channel 51 and the cooking chamber.

[0105] In the above embodiment, after cooking is completed, the on / off device 53 is opened to connect the cooking chamber with the steam exhaust channel 51, and the steam in the cooking chamber is discharged under the action of the exhaust fan 52. At the same time, when it is not necessary to discharge steam, the on / off device 53 is closed to maintain the sealing of the cooking chamber and ensure cooking efficiency.

[0106] In some embodiments, the on / off device 53 can be opened as needed during cooking to release steam. For moisture-sensitive ingredients, this allows for rapid reduction of humidity during cooking, achieving the desired cooking effect. Examples include air frying, a cooking method that requires high humidity levels.

[0107] In some embodiments, the on / off device 53 further includes an exhaust component 5323. It is movably mounted at the steam exhaust port 10 to control the opening and closing of the steam exhaust port 10.

[0108] In some embodiments, the switching device 53 further includes a drive component 532, one end of which is fixedly mounted on the outside of the steam exhaust device 5. The other end of the drive component 532 extends into the steam exhaust passage 51 and is connected to the exhaust component 5323.

[0109] The drive component 532 drives the exhaust component 5323 to open the steam outlet 10 so that the cooking chamber is connected to the steam exhaust device 5.

[0110] In the above-described manner, by setting the drive component 532 to drive the exhaust component 5323, the exhaust process is automated, and the steam is discharged in a timely manner. By controlling the operating state of the drive component 532, the on / off state of the steam outlet 10 can be controlled, allowing for on / off control according to different usage scenarios.

[0111] Reference Figure 7 The drive component 532 includes a drive motor 5321 and a drive rod 5322. One end of the drive rod 5322 is connected to the drive end of the drive motor 5321. The other end of the drive rod 5322 is connected to the exhaust component 5323 to drive the exhaust component 5323 to open or close the steam exhaust port 10.

[0112] In some embodiments, the on / off device 53 includes an electromagnetic lock. The electromagnetic lock opens or closes the steam outlet 10.

[0113] In some embodiments, the cooking apparatus 100 further includes a sealing member 533 disposed between the exhaust member 5323 and the steam exhaust port. This ensures the sealing of the cooking cavity during cooking and reduces heat loss. (See also...) Figure 7 The sealing element 533 is wrapped around the exhaust component 5323, mainly to seal the steam exhaust channel 51, ensuring that steam will not overflow from here when closed.

[0114] In some embodiments, the seal 533 may also be located at the steam outlet 10. When the venting component 5323 is used to close the steam outlet 10, the venting component 5323 and the seal 533 are in close contact to prevent the cavity from leaking air from the steam outlet 10.

[0115] In some embodiments, refer to Figure 9-10 A condensation chamber 551 is formed within the steam discharge channel 51. A cooling element 541 is disposed within the condensation chamber 551. By cooling the steam through the condensation chamber 551, the humidity of the gas outside the output housing 1 is reduced.

[0116] In some embodiments, refer to Figure 9-10 The condensing component includes a cooling element 541 disposed within the steam discharge passage 51, and the cooling element 541 is disposed opposite to the steam discharge outlet 10. In some embodiments, the cooling element 541 is installed in the condensing chamber 551 to reduce the steam temperature.

[0117] By setting up the cooling component 541, steam can be condensed and collected during the steam exhaust process, reducing the water content of the exhaust steam and ensuring that the kitchen space is dry.

[0118] In some embodiments, refer to Figure 10-11 The condensation chamber 551 further includes a guide surface 542, which is disposed opposite to the air inlet of the exhaust fan 52. The guide surface 542 is configured as an inclined surface sloping towards the inner liner 2 to guide the condensate into the cooking chamber. (See reference...) Figure 11 In the middle, the blue line is a schematic horizontal line to represent the tilting characteristics of the guide surface 542.

[0119] By setting an inclined guide surface 542, the condensate flows to the lowest point and eventually flows back into the cavity, ensuring that no water accumulates 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 3 and then be blown into the room.

[0120] Reference Figure 11The design details of the condenser chamber 551 are all inclined from different angles to ensure that the condensate flows to the lowest point and eventually flows back into the chamber. This ensures that water will not accumulate in the condenser chamber 551 and that the condensation effect will not be affected by a large amount of water vapor entering the heat dissipation duct 3 and being blown into the room.

[0121] In some embodiments, to achieve a better condensation effect and reduce steam discharge, the condensing component further includes a heat dissipation element 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 dissipation element 543 can quickly absorb the heat in the steam discharge channel 51 and cool the gas in the channel.

[0122] In some embodiments, the cooling element 541 is configured as a phase change material, which is installed within the condensation chamber 551. In addition to the absorption of steam by the metal plate in the relevant condensation scheme, the phase change material absorbs heat from the steam through phase change heat absorption.

[0123] In some embodiments, refer to Figure 8 The heat sink 543 is configured as a heat sink, which is arranged and installed on the outer wall constituting the condensation chamber 551. The heat sinks can absorb heat from the phase change material, enabling rapid cooling so that it can absorb more steam heat and improve the utilization efficiency of the phase change material. On the other hand, they can also quickly absorb heat from the condensation chamber 551, accelerating its cooling.

[0124] In some embodiments, the heat sink is disposed on one side of the cooling fan 4. The cooling fan 4 absorbs heat from the surrounding area and can cool the heat sink to achieve a better heat dissipation effect.

[0125] Through the combined effects of phase change materials and heat sinks, better heat dissipation is achieved.

[0126] In some embodiments, the phase change material can be configured as a heat dissipation layer, installed on the inner wall of the condensation chamber 551. In some embodiments, the heat dissipation layer can be positioned opposite the steam outlet 10 to improve contact efficiency.

[0127] In some embodiments, the cooking appliance 100 may not have an on / off device 53 at the steam outlet 10, and a rapid steam discharge scheme can also be implemented in the cooking cavity. Of course, a steam condensation scheme can also be implemented.

[0128] In some embodiments, the cooking appliance 100 may not be equipped with an exhaust fan 52. In this case, although the steam exhaust speed decreases, the condensation function during the steam exhaust process can still be achieved normally.

[0129] In some embodiments, the cooking appliance 100 is not equipped with an exhaust fan 52 and an on / off device 53 in order to implement a condensation scheme during the steam exhaust process.

[0130] In some embodiments, the cooking appliance 100 further includes a steam device (not shown) which is detachably disposed between the housing 1 and the inner liner 2. The steam device has a water storage cavity formed inside, and the outer wall of the steam device is provided with a steam hole communicating with the storage cavity and the cooking cavity.

[0131] The water in the containment cavity can evaporate to form steam, and the steam can enter the cooking cavity through the steam hole.

[0132] In some embodiments, the cooking apparatus further includes a humidity detection device disposed within the cooking chamber, used to detect the humidity value within the cooking chamber and transmit the humidity value to the controller. The humidity value detected by the humidity detection device corresponds to different cooking ingredients, allowing steam to be released at necessary points. For example, for humidity-sensitive ingredients, if excessive humidity is detected during cooking, the steam vent 10 can be opened to meet cooking requirements.

[0133] The following describes one control logic of the cooking device 100.

[0134] When cooking begins, the steam vent 10 automatically opens or closes according to the cooking requirements of the ingredients to control the amount of steam in the cooking chamber. This means controlling the humidity within the cooking chamber to meet the moisture requirements for cooking the ingredients.

[0135] After cooking is finished, the control drive unit 532 is activated to open the steam outlet 10, thereby quickly expelling the condensed air. Then, the door is opened to remove the food.

[0136] In some embodiments, the user can be notified to open the door to retrieve food after the venting process is complete and the humidity inside the cooking cavity reaches a certain standard. In some embodiments, the door can be opened only after a certain period of time has elapsed since cooking has ended, to prevent burns.

[0137] This application also proposes a scheme for recovering condensate from steam.

[0138] Reference Figure 12-17 In some embodiments, the steam discharge device 5 includes a steam discharge channel 51, one end of which is connected to a steam discharge outlet 10.

[0139] In some embodiments, the condensing chamber 551 is connected to the side of the steam discharge channel 51 away from the steam discharge outlet 10, and is used to cool the steam entering the condensing chamber 551.

[0140] In some embodiments, the steam exhaust device 5 further includes a condensing chamber 551. The condensing chamber 551 is connected to the outlet of the exhaust fan 52 to receive steam from the cooking chamber and to cool the steam entering the condensing chamber 551. In some embodiments, the condensing chamber 551 has an opening connected to the outlet of the steam exhaust channel 51 to receive extracted steam.

[0141] In some embodiments, the steam exhaust device 5 further includes a condensate outlet 552, which connects the condensation chamber 551 and the cooking chamber to allow condensate to flow into the cooking chamber.

[0142] In the above embodiment, by setting a condensation chamber 551 at the air outlet of the steam exhaust channel 51, the steam exhaust channel 51 is opened to discharge and condense moisture when the humidity in the cooking chamber is high, and the condensate can be recovered, preventing moisture from being blown into the room, and the condensate is also treated well.

[0143] The steam exhaust device 5 also includes an exhaust fan 52. The exhaust fan 52 is installed inside the steam exhaust passage 51 and is used to extract steam from the cooking chamber.

[0144] Steam in the cooking chamber is condensed in the condensing chamber 551 by the exhaust fan 52, passing through the steam outlet 10 and the steam discharge channel 51.

[0145] In the above embodiment, by setting an exhaust fan 52, power is provided for the steam flow, so as to quickly vent the steam in the cooking cavity.

[0146] In some embodiments, the cooking appliance further includes a condensate drain pipe 553. The condensate drain pipe 553 is used to connect the condensation chamber and the inner liner.

[0147] In some embodiments, the steam discharge channel 51 includes a volute for mounting an exhaust fan 52, a second duct connecting the air inlet of the volute and the steam outlet 10, and a third duct connecting the air outlet of the volute and the condensation chamber 551. Under the action of the exhaust fan 52, steam passes through the steam outlet 10, the second duct, the volute, and the third duct before entering the condensation chamber 551.

[0148] In some embodiments, the steam discharge channel 51 includes a volute for mounting an exhaust fan 52 and a second duct connecting the air inlet of the volute and the steam outlet 10. The air outlet of the volute is connected to the condensation chamber 551. Under the action of the exhaust fan 52, steam enters the condensation chamber 551 after passing through the steam outlet 10, the second duct, and the volute.

[0149] In some embodiments, the steam discharge passage 51 includes a volute for mounting an exhaust fan 52 and a third air duct connecting the air outlet of the volute and the condensation chamber 551. The air inlet of the volute is connected to the steam discharge outlet 10. Under the action of the exhaust fan 52, steam passes through the steam discharge outlet 10, the volute, and the third air duct before entering the condensation chamber 551.

[0150] In some embodiments, the steam exhaust passage 51 includes a volute on which an exhaust fan 52 is mounted. The volute is installed between the housing 1 and the inner liner 2. The air inlet of the volute is connected to the steam outlet 10, and the steam outlet of the volute is connected to the condensation chamber 551. Under the action of the exhaust fan 52, steam flows through the volute and is then discharged from the cooking chamber.

[0151] In the above embodiment, an exhaust fan 52 is provided to power the steam flow, enabling rapid emptying of steam from the cooking cavity. An intelligent on / off control device 53 opens the steam exhaust channel 51 to release and condense moisture when the humidity in the cooking cavity is high, and also allows for condensate recovery, preventing moisture from being blown into the room and ensuring proper treatment of the condensate.

[0152] In some embodiments, the condensation chamber includes a channel body, one end of which is connected to the side of the steam discharge channel 51 away from the steam discharge outlet 10, and the other end of the channel body is closed. The condensate outlet 552 is located on the side wall of the channel body near the inner liner.

[0153] One end of the channel body receives and cools the steam from the cooking chamber, and then discharges the condensate into the channel body. This allows for the recycling of condensate.

[0154] In some embodiments, the steam discharge device 5 includes a condensing component disposed within a condensing chamber for condensing the steam within the condensing chamber, thereby improving the condensation efficiency within the condensing chamber.

[0155] In some embodiments, the condensing component includes a cooling element 541. The cooling element is disposed within the condensing chamber and is used to absorb heat from the steam to cool the steam entering the condensing chamber, thereby reducing the steam temperature.

[0156] By setting up the cooling component 541, steam can be condensed and collected during the steam exhaust process, reducing the water content of the exhaust steam and ensuring that the kitchen space is dry.

[0157] In some embodiments, to achieve a better condensation effect and reduce steam exhaust, the condensing component further includes a heat dissipation element 543, which is disposed outside the condensing chamber 551 and close to the outer wall of the condensing chamber 551, to exchange heat with the airflow inside the condensing chamber 551. The heat dissipation element 543 can quickly absorb heat from the condensing chamber 551 to cool the gas inside the condensing chamber 551.

[0158] In some embodiments, the cooling element 541 is configured as a phase change material, which is installed within the condensation chamber 551. In addition to the metal plate absorbing steam in the relevant condensation scheme, the phase change material absorbs heat from the steam through phase change heat absorption.

[0159] In some embodiments, the heat sink 543 is configured as a heat sink, which is arranged and installed on the outer wall constituting the condensation chamber 551. The heat sinks can absorb heat from the phase change material, enabling rapid cooling so that it can absorb more steam heat and improve the utilization efficiency of the phase change material. On the other hand, they can also rapidly absorb heat from the condensation chamber 551, accelerating its cooling.

[0160] In some embodiments, the phase change material can be configured as a heat dissipation layer, mounted on the inner wall of the condensation cavity 551. In some embodiments, the heat dissipation layer can be laid flat inside the condensation cavity 551 to improve contact efficiency.

[0161] In some embodiments, the steam discharge device 5 further includes a condensation channel 554, which is disposed outside the condensation chamber 551. This reduces heat exchange between the condensation chamber 551 and the inner liner 2, thus affecting the condensation effect.

[0162] By designing the steam exhaust channel 51 at the top to facilitate the exhaust of steam, the exhaust fan 52 directly works on the steam in the cooking chamber, achieving a rapid exhaust effect.

[0163] In the condensate recovery scheme, the steam outlet 10 can still be equipped with an on / off device 53. This controls whether steam is discharged from the cooking cavity. The on / off device 53 is the same as in the above scheme and will not be described again here. The on / off device 53 can control the opening and closing of the channel, opening it when needed and closing it when not needed.

[0164] In this embodiment, the steam exhaust device 5 is disposed between the inner liner 2 and the housing 1. The condensation chamber 551 is connected to the side of the steam exhaust channel 51 away from the steam outlet 10 to receive and cool the steam from the cooking chamber. Condensate flows from the condensation chamber 551 into the cooking chamber through the condensate outlet 552. This achieves condensate recovery, preventing moisture from being blown into the room, and ensuring better treatment of the condensate. Furthermore, it effectively controls humidity to meet the different humidity requirements of various ingredients.

[0165] The term "connection" as used in this application refers to the spatial relationship between two components or parts (hereinafter collectively referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.

[0166] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.
