Description

Technical Field

[0001] The present invention relates to the field of cooking devices, and in particular to a cooking device and an integrated stove having the cooking device. Background Art

[0002] An integrated stove is a device that integrates a stove with other household appliances, for example, a gas stove with a cooking device, a range hood, or a disinfection cabinet. For example, existing integrated stoves are disclosed in Chinese invention patent application number CN202011409253.6 (publication number CN112555906A), Chinese utility model patent authorization number ZL 202022154907.7 (authorization number CN213686958U), and Chinese utility model patent application number CN202010107110.3 (publication number CN111389135A).

[0003] When a stove is combined with a cooking device (such as a steamer, oven, steam-oven, or all-in-one steam-and-bake), the integrated stove not only functions as a stove but also as a cooking device (such as steaming and baking). The door of existing cooking devices is mounted on the door opening via a damping hinge. During cooking, the temperature inside the cooking pot is high, especially in baking mode, where the temperature can reach around 200°C. However, the damper of the damping hinge must operate within a temperature range of no higher than 70°C.

[0004] Furthermore, current ovens, steam ovens, and other cooking devices with baking functions are unable to effectively achieve efficient exhaust, thus affecting the cooking effect of foods that require high dehumidification, such as the texture of melted beans, dried fruits and vegetables, cakes, and puffs, and affecting the coloring of meat ingredients. In addition, the steam generators in current steaming devices such as steamers and steam ovens are becoming increasingly powerful. While this improves steaming efficiency, it also results in a large amount of residual steam in the inner pot at the end of cooking. When the door is opened after cooking, a large amount of remaining steam in the inner pot escapes and sprays directly at the user, posing a risk of burns and affecting the user experience. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a cooking device with a damping hinge heat dissipation function in view of the existing technology.

[0006] The second technical problem to be solved by the present invention is to provide a cooking device with a high-efficiency dehumidification function in a baking mode in response to the existing technology.

[0007] The third technical problem to be solved by the present invention is to provide a cooking device with a door heat dissipation function in response to the existing technology.

[0008] The fourth technical problem to be solved by the present invention is to provide a cooking device that can prevent smoke from directly spraying onto the user when the door is opened at the end of the steaming mode, in response to the existing technology.

[0009] The fifth technical problem to be solved by the present invention is to provide a cooking device with an inner pot cooling function in response to the existing technology.

[0010] The sixth technical problem to be solved by the present invention is to provide an integrated stove with the above-mentioned cooking device in view of the existing technology.

[0011] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a cooking device, comprising a box body and a door body, the door body being rotatably mounted on the opening of the box body through a damping hinge, the damping hinge comprising a head and a body on which a damper is installed, and is characterized in that it also comprises a blower fan, a heat exchange chamber and an air guide channel arranged in the above-mentioned box body, the heat exchange chamber having an air inlet and a first air outlet, the above-mentioned air guide channel being adjacent to the above-mentioned damping hinge and capable of heat exchange with the damping hinge, the air inlet of the above-mentioned heat exchange chamber being fluidly connected to the air outlet of the above-mentioned blower fan, the first air outlet of the heat exchange chamber being fluidly connected to the air inlet port of the above-mentioned air guide channel, and the air outlet port of the air guide channel being connected to the outside world.

[0012] Furthermore, the damping hinge further comprises an air duct extending along the length of the damping hinge body and arranged in parallel with the damping hinge body, wherein the inner cavity of the air duct constitutes the air guide channel. The damper of the damping hinge is mounted on the damping hinge body. By arranging the damping hinge body and the air duct in parallel, the cold air in the air duct can better exchange heat with the hot air surrounding the damper.

[0013] Furthermore, the wall of one side of the air duct is recessed inward along its length to form a mounting groove, into which the damping hinge body is embedded. This allows the cool air in the air duct to wrap around the damping hinge body, further reducing the temperature around the damper.

[0014] Furthermore, the front of the housing is open, the damping hinge is mounted on one side of the lower end of the housing, and the air duct extends in a front-to-back direction. The door body comprises an outer door panel and an inner door panel, with a ventilation layer formed between the outer and inner door panels. The upper and lower ends of the ventilation layer are connected to the outside world, and the front end of the air duct extends forward and smoothly upward, with the outlet of the air duct located in the ventilation layer. This allows cool air from the air duct to enter the ventilation layer, thereby cooling the door body and preventing excessive surface temperature.

[0015] Furthermore, the heat exchange chamber includes an inner liner disposed within the housing, the inner liner having an air inlet, and the heat exchange chamber having a second air outlet in fluid communication with the air inlet. This allows gas blown into the heat exchange chamber by the blower to also flow into the inner liner. Specifically, when the humidity within the inner liner exceeds a set value, the blower operates to blow the gas within the housing into the heat exchange chamber, thereby dehumidifying the inner liner. Because the gas within the housing has a certain temperature, the gas blown into the inner liner does not cause the internal temperature of the inner liner to drop rapidly.

[0016] Furthermore, a control element is movably mounted in the heat exchange chamber to control the connection between the air inlet and either the first or second air outlet. This allows the control element to switch the air path connection state in the heat exchange chamber according to cooking needs: when heat dissipation is required for the damper of the damping hinge, the control element connects the air inlet to the first air outlet; when moisture removal, rapid smoke vapor processing, or rapid cooling of the inner pot is required, the control element connects the air inlet to the second air outlet.

[0017] Furthermore, the control member is a baffle rotatably mounted in the heat exchange chamber. The baffle can swing back and forth between the air inlet and the first air outlet and between the air inlet and the second air outlet. When the baffle is rotated to the position between the air inlet and the second air outlet, the air inlet is connected to the first air outlet; when the baffle is rotated to the position between the air inlet and the first air outlet, the air inlet is connected to the second air outlet. This allows for better control over the switching of different air paths in the heat exchange chamber.

[0018] Furthermore, a first refrigeration device for cooling the gas at the first air outlet is installed in the heat exchange chamber. The first refrigeration device is used to actively cool the gas at the first air outlet, thereby significantly improving the heat dissipation effect of the damping hinge. At the same time, a second refrigeration device for reducing the temperature of the gas at the second air outlet is also installed in the heat exchange chamber. In this way, when the smoke vapor needs to be quickly processed in the inner tank (for example, at the end of cooking), the second refrigeration device is turned on, and the gas at the second air outlet is cooled. The cooled gas is introduced into the inner tank through the second air outlet to achieve rapid condensation of the smoke vapor in the inner tank, thereby avoiding a large amount of smoke vapor in the inner tank from being directly sprayed onto the user when the door is opened after cooking. In addition, when the inner tank needs to be quickly cooled after cooking, the second refrigeration device is turned on to introduce cold air into the inner tank, thereby cooling the inner tank.

[0019] Furthermore, the control member is disposed opposite the air inlet, and the rotating end of the control member is capable of swinging back and forth along the inner surface of the heat exchange chamber where the air inlet is located. Furthermore, the first air outlet and the first refrigeration device are disposed on one side of the control member, while the second air outlet and the second refrigeration device are disposed on the other side of the control member. Thus, the control member can better control the air path connectivity in the heat exchange chamber.

[0020] Furthermore, the inner surface of the heat exchange chamber where the air inlet is located is an arc-shaped surface extending along the swing trajectory of the control member. The rotating end of the control member is arc-shaped to match this arc-shaped surface, and the swing centerline of the control member is aligned with the centerline of the air inlet. This not only guides the rotation of the control member, ensuring smooth swinging, but also facilitates the formation of a sealed cavity structure between the air inlet and either air outlet.

[0021] Furthermore, the device includes a water tank, a steam generator, and a preheating chamber. One end of a water outlet pipe is connected to the water outlet of the water tank, and the other end is connected to the water inlet of the steam generator. The water outlet pipe is disposed in the preheating chamber, and a heating component is installed in the preheating chamber for heating water in the water outlet pipe. The heating component in the preheating chamber can preheat the water in the water outlet pipe, and the preheated water enters the steam generator, thereby improving the efficiency of steam generation.

[0022] Furthermore, the preheating chamber is adjacent to the heat exchange chamber, the first cooling device is a first thermosensitive semiconductor, and the second cooling device is a second thermosensitive semiconductor. Furthermore, the hot end of the first thermosensitive semiconductor and the hot end of the second thermosensitive semiconductor constitute the heating assembly. In this way, each cooling device can simultaneously heat the gas in the preheating chamber while cooling the gas at its corresponding gas outlet, and simultaneously heat the cold water flowing through the preheating chamber.

[0023] Furthermore, the cooking device further includes a heat exchange box having a partition therein, wherein the inner cavity of the heat exchange box on one side of the partition constitutes the heat exchange chamber, while the inner cavity of the heat exchange box on the other side constitutes the preheating chamber. The first and second thermosensitive semiconductors are both mounted on the partition, with the cold end and hot end of each thermosensitive semiconductor respectively located in the heat exchange chamber, and the control member is rotatably mounted on the partition. This simplifies the internal structure of the cooking device, effectively achieving the heat exchange chamber and preheating chamber, while also ensuring a stable arrangement of the first and second refrigeration devices, and allowing the cold and hot ends of each refrigeration device to be located in corresponding chambers.

[0024] Furthermore, the inner pot is provided with a steam inlet, and a hot air blower impeller is mounted on the inner surface of the back panel of the inner pot. A back heating pipe is disposed around the outer periphery of the impeller. A steam nozzle is also disposed within the inner pot for spraying steam toward the back heating pipe. The steam inlet is fluidly connected to the steam outlet of the steam generator, while the steam inlet port of the steam nozzle is fluidly connected to the steam inlet. High-temperature steam ejected from the steam nozzle is sprayed onto the back heating pipe, achieving secondary heating. The centrifugal force of the impeller rapidly directs the heated steam into the inner pot, thereby achieving a high-temperature degreasing effect on meat while maintaining the food's texture.

[0025] The technical solution adopted to further solve the sixth technical problem mentioned above is: an integrated stove, characterized in that it has the cooking device as described above.

[0026] Furthermore, the invention further includes a stove mounted on the cooking device, the stove comprising a bottom plate with an upper opening and a panel covering the bottom plate opening, the panel having an exhaust window formed on the rear side thereof, and an exhaust port formed on the back side of the inner pot of the cooking device, the exhaust port being in fluid communication with the exhaust window. Thus, gas in the inner pot can be discharged from bottom to top through the exhaust window, and can be quickly discharged by a range hood above the exhaust window, particularly when dehumidifying the inner pot, rapidly treating smoke vapor, and rapidly cooling the pot.

[0027] Compared with the existing technology, the advantages of the present invention are: when the blower is in working state, relatively low-temperature gas (relative to the high temperature at the damping hinge) is blown into the heat exchange chamber and introduced into the air guide channel to exchange heat with the damping hinge, thereby achieving heat dissipation and cooling of the damping hinge, avoiding the damper in the damping hinge from having an excessively high working environment temperature (generally not higher than 70°C), and extending the service life of the damper.

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0037] like Figures 1 to 7 As shown, an integrated stove with a cooking device includes a cooking device 2 and a stove 1 disposed above the cooking device 2. The stove 1 includes a bottom plate 11 with an upper opening and a panel 12 covering the opening of the bottom plate 11. An exhaust window 121 is defined on the rear side of the panel 12, and an exhaust grille 1211 is embedded in the exhaust window 121. The cooking device 2 includes a housing 20 with an upper opening and a door 24. An inner pot 21 is disposed in the housing 20, and an exhaust port 213 is defined on the back of the inner pot 21. The exhaust port 213 is in fluid communication with the exhaust window 121. In this embodiment, an exhaust box (not shown) is connected below the exhaust window 121. The bottom of the exhaust box has an air inlet port, which is connected to the exhaust port 213 of the inner pot 21 via an exhaust pipe 10. In this way, the gas in the inner tank 21 can be discharged from bottom to top through the exhaust window 121, and can be discharged quickly under the action of the range hood above the exhaust window 121, especially when the inner tank 21 is dehumidified, the smoke is quickly processed, and the temperature is quickly cooled, a good rapid exhaust effect can be achieved.

[0038] Furthermore, the left and right sides of the lower end of the door body 24 are rotatably connected to the box body 20 through hinges respectively, one of which is a damping hinge 25 (i.e., a damper is installed), and the damping hinge 25 includes a head 251 and a body 252 equipped with a damper (not shown). The cooking device 2 also includes a blower 5, a heat exchange chamber 301 and an air guide channel 40 arranged in the above-mentioned box body 20. The heat exchange chamber 301 has an air inlet 3011 and a first air outlet 3012, and a first refrigeration device 33 for cooling the gas at the first air outlet 3012 is installed in the heat exchange chamber 301. The above-mentioned air guide channel 40 is adjacent to the above-mentioned damping hinge 25 and can exchange heat with the damping hinge 25. The air inlet 3011 of the above-mentioned heat exchange chamber 301 is fluidically connected to the air outlet of the above-mentioned blower 5. The first air outlet 3012 of the heat exchange chamber 301 is connected to the air inlet port 401 of the above-mentioned air guide channel 40 through the first air outlet pipe 4011, and the air outlet port 402 of the air guide channel 40 is connected to the outside world.

[0039] Thus, in the present invention, when the blower fan 5 is in working state, gas is blown into the heat exchange chamber 301, and the gas entering the heat exchange chamber 301 is cooled by the first refrigeration device 33 at the first air outlet 3012. The cooled gas enters the air guide channel 40 and exchanges heat with the damping hinge 25, thereby realizing heat dissipation and cooling of the damping hinge 25, avoiding the working environment temperature of the damper in the damping hinge 25 from being too high (generally not higher than 70°C), and extending the service life of the damper.

[0040] Specifically, in this embodiment, the door body 24 includes an outer door panel 241 and an inner door panel 242. In this embodiment, the outer door panel 241 and the inner door panel 242 respectively serve as the outer and inner glass panels. A ventilation layer 240 is formed between the outer and inner glass panels. The upper and lower ends of the ventilation layer 240 are connected to the outside. The cooking device 2 also includes an air duct 4 extending along the length of the body 252 of the damping hinge 25 and arranged in parallel with the body 252 of the damping hinge 25. The air duct 4 extends in the front-to-back direction, and the inner cavity of the air duct 4 constitutes the air guide channel 40. Furthermore, the front end of the air duct 4 extends forward and smoothly upward, so that the air outlet port 402 of the air guide channel 40 is located in the ventilation interlayer 240. In this way, the relatively cold air in the air duct 4 (relative to the hot air to be dissipated in the ventilation interlayer 240) enters the ventilation interlayer 240, driving the gas in the ventilation interlayer 240 to flow from bottom to top, thereby achieving heat dissipation for the door body 24 and preventing the surface temperature of the door body 24 from being too high. Preferably, an air outlet connector 100 is provided on the front end of the air duct 4, so that the cold air in the air duct 40 can enter the ventilation interlayer 240 more smoothly to achieve heat dissipation for the door body 24.

[0041] The damper of the damping hinge 25 is mounted on its body 252. By arranging the body 252 of the damping hinge 25 in parallel with the air duct 4, the cold air in the air duct 4 can better exchange heat with the hot air surrounding the damper. At the same time, the cold air in the air duct 40 is passed into the ventilation interlayer 240 to dissipate heat from the door body 24, thereby preventing excessive surface temperature of the door body 24. Preferably, the wall of one side of the air duct 4 is recessed inward along its length to form a mounting groove 41. The body 252 of the damping hinge 25 is embedded in this mounting groove 41, so that the cold air in the air duct 4 wraps around the body 252 of the damping hinge 25, thereby further reducing the temperature around the damper.

[0042] Furthermore, the inner container 21 of the present invention is provided with an air inlet 211, and the heat exchange chamber 301 also has a second air outlet 3013 connected to the air inlet 211 via a second air outlet pipe 2111. This allows the gas blown into the heat exchange chamber 301 by the blower 5 to also flow into the inner container 21. Specifically, in baking mode, when the humidity in the inner container 21 exceeds a set value, the blower 5 operates, blowing the gas within the housing 20 into the heat exchange chamber 301 to dehumidify the inner container 21. Because the gas within the housing 20 has a certain temperature, the gas blown into the inner container 21 does not cause the internal temperature of the inner container 21 to drop rapidly. In this embodiment, the blower 5 utilizes a PWM fan, which can achieve stepless control of the air volume output to meet the needs of regulating the dehumidification speed of the inner container 21. For example, baking dried fruits requires strong and high-speed dehumidification, while baking cakes requires continuous low-speed dehumidification to prevent excessive heat loss.

[0043] Preferably, the heat exchange chamber 301 is also equipped with a second refrigeration device 34 for cooling the gas at the second air outlet 3013. When the liner 21 needs to be quickly cooled (e.g., at the end of cooking), the second refrigeration device 34 is turned on, cooling the gas at the second air outlet 3013. The cooled gas is then introduced into the liner 21 through the second air outlet 3013, thereby rapidly condensing the fumes in the liner 21 and preventing a large amount of fumes from being sprayed directly onto the user when the door is opened after cooking. Furthermore, when the liner 21 needs to be quickly cooled after cooking, the second refrigeration device 34 is turned on to introduce cold air into the liner 21, thereby cooling the liner 21.

[0044] Furthermore, a control member 32 is movably mounted in the heat exchange chamber 301 for controlling the connection between the air inlet 3011 and either the first air outlet 3012 or the second air outlet 3013. This allows the control member 32 to switch the air path connection state in the heat exchange chamber 301 according to cooking needs: when the damper of the damping hinge 25 needs to dissipate heat, the control member 32 connects the air inlet 3011 to the first air outlet 3012; when the inner pot 21 needs to be dehumidified or smoke vapor needs to be rapidly processed or cooled, the control member 32 connects the air inlet 3011 to the second air outlet 3013. Specifically, in this embodiment, a control member 32 is movably mounted in the heat exchange chamber 301 for controlling the connection between the air inlet 3011 and either the first air outlet 3012 or the second air outlet 3013. In this way, the air path connection state in the heat exchange chamber 301 can be switched and controlled through the control component 32 according to cooking needs: when the damper of the damping hinge 25 needs to dissipate heat, the air inlet 3011 is connected to the first air outlet 3012 through the control component 32; when the inner tank 21 needs to be dehumidified or the smoke needs to be quickly processed or quickly cooled, the air inlet 3011 is connected to the second air outlet 3013 through the control component 32.

[0045] Specifically, the control member 32 is a baffle rotatably mounted within the heat exchange chamber 301. The baffle can swing back and forth between the air inlet 3011 and the first air outlet 3012, and between the air inlet 3011 and the second air outlet 3013. Furthermore, when the baffle is rotated to position itself between the air inlet 3011 and the second air outlet 3013, the air inlet 3011 communicates with the first air outlet 3012. When the baffle is rotated to position itself between the air inlet 3011 and the first air outlet 3012, the air inlet 3011 communicates with the second air outlet 3013. This allows for better control over the switching of different air paths within the heat exchange chamber 301.

[0046] Preferably, the control member 32 is disposed opposite the air inlet 3011, and the rotating end of the control member 32 is capable of swinging back and forth along the inner surface of the heat exchange chamber 301 where the air inlet 3011 is located. Furthermore, the first air outlet 3012 and the first refrigeration device 33 are disposed on one side of the control member 32, while the second air outlet 3013 and the second refrigeration device 34 are disposed on the other side of the control member 32. This allows the control member 32 to better control the air path connectivity within the heat exchange chamber 301. Further preferably, the inner surface of the heat exchange chamber 301 where the air inlet 3011 is located is an arc-shaped surface extending along the swing trajectory of the control member 32, and the rotating end of the control member 32 is in an arc shape that matches the arc-shaped surface, with the swing centerline of the control member 32 directly aligned with the centerline of the air inlet 3011. On the one hand, it can guide the rotation of the control member 32 so that the control member 32 swings smoothly. On the other hand, it is beneficial for the air inlet 3011 and any air outlet to form a sealed cavity structure.

[0047] The cooking device 2 in this embodiment also includes a water tank 22, a steam generator 23, and a preheating chamber 302. One end of a water outlet pipe 6 is connected to the water outlet of the water tank 22, while the other end is connected to the water inlet of the steam generator 23. The water outlet pipe 6 extends through the preheating chamber 302, and a heating assembly is installed in the preheating chamber 302 for heating the water in the water outlet pipe 6. This heating assembly in the preheating chamber 302 preheats the water in the water outlet pipe 6, which then enters the steam generator 23, improving the efficiency of steam generation. In this embodiment, the water tank 22 is located to the right of the inner pot 21, and the steam generator 23 is mounted on the back of the inner pot 21. A water pump 61 and a water valve 62 are installed on the water outlet pipe 6. Furthermore, the preheating chamber 302 is adjacent to the heat exchange chamber 301. The first cooling device 33 is a first thermosensitive semiconductor, while the second cooling device 34 is a second thermosensitive semiconductor. Furthermore, the hot end 3a of the first thermosensitive semiconductor and the hot end 3a of the second thermosensitive semiconductor constitute the heating assembly. In this way, each cooling device can simultaneously heat the gas in the preheating chamber 302 while cooling the gas at its corresponding gas outlet, and simultaneously heat the cold water flowing through the preheating chamber 302.

[0048] Specifically, the cooking device 2 in this embodiment also includes a heat exchange box 3, which is also arranged on the right side of the inner pot 21. A partition 31 is provided in the heat exchange box 3. The inner cavity of the heat exchange box 3 on one side of the partition 31 constitutes the above-mentioned heat exchange cavity 301, and the inner cavity of the heat exchange box 3 on the other side constitutes the above-mentioned preheating cavity 302. The above-mentioned first thermosensitive semiconductor and the second thermosensitive semiconductor are both installed on the partition 31, and the cold end 3b of each thermosensitive semiconductor is respectively located in the above-mentioned heat exchange cavity 301 and the hot end 3a is respectively located in the above-mentioned heat exchange cavity 301. The above-mentioned control component 32 is rotatably installed on the partition 31 through a rotating shaft 321, and the center line of the rotating shaft 321 is the swing center line of the control component 32. This can simplify the internal structure of the cooking device 2, better realize the above-mentioned heat exchange chamber 301 and preheating chamber 302, and at the same time achieve a stable setting of the first refrigeration device 33 and the second refrigeration device 34, and enable the cold end 3b and hot end 3a of each refrigeration device to be located in the corresponding chamber.

[0049] Preferably, a steam inlet 212 is provided on the inner pot 21, and a hot air blower impeller 7 is installed on the inner surface of the back plate of the inner pot 21, and a back heating pipe 8 is provided around the outer periphery of the impeller 7. A steam nozzle 9 for spraying steam toward the back heating pipe 8 is also provided in the inner pot 21. The steam inlet 212 is connected to the steam outlet of the steam generator 23 through the steam inlet pipe 2121, and the steam inlet port of the steam nozzle 9 is fluidically connected to the steam inlet (212). The high-temperature steam sprayed by the steam nozzle 9 is sprayed onto the back heating pipe 8 to achieve secondary heating. The steam after secondary heating is quickly introduced into the inner pot 21 under the action of the centrifugal force of the impeller 7, thereby achieving the cooking effect of high-temperature defatting of meat and ensuring the taste of the food while defatting.

[0050] The working process of the present invention is as follows:

[0051] Cooling the damping hinge 25 and door 24: The control member 32 swings until the air inlet 3011 of the heat exchange chamber 301 is connected to the first air outlet 3012, and the blower 5 and the first refrigeration unit 33 begin operation. Warm air in the cabinet 20 is blown into the heat exchange chamber 301 by the blower 5. The first refrigeration unit 33 cools the air at the first air outlet 3012. The cooled air enters the air guide duct 40 and mixes with the air around the damping hinge 25, cooling the damper in the damping hinge 25. Simultaneously, the cooled air in the air guide duct 40 enters the ventilation interlayer 240 of the door 24, cooling the door 24 and preventing the surface temperature of the door 24 from overheating.

[0052] To dehumidify the inner pot 21 in grilling mode, the control member 32 swings until the air inlet 3011 of the heat exchange chamber 301 is in communication with the second air outlet 3013. The blower 5 operates, and the second refrigeration unit 34 stops operating. Warm air within the cabinet 20 is drawn into the heat exchange chamber 301 by the blower 5 and then into the inner pot 21 through the second air outlet 3013, dehumidifying the inner pot 21. Since the air entering the inner pot 21 is warm, the dehumidification process does not cause the internal temperature of the inner pot 21 to drop rapidly.

[0053] Rapid condensation of smoke or rapid cooling of the inner pot 21: The control member 32 swings until the air inlet 3011 of the heat exchange chamber 301 is connected to the second air outlet 3013, and the blower 5 and the second refrigeration unit 34 operate simultaneously. Warm air from the housing 20 is blown into the heat exchange chamber 301 by the blower 5. The warm air entering the heat exchange chamber 301 is cooled by the second refrigeration unit 34 at the second air outlet 3013. The cooled air then enters the inner pot 21, rapidly condensing the smoke in the inner pot 21. The resulting mixture of condensed water and oil droplets is collected and processed, while the remaining smoke is driven upward by the range hood above the cooker 1 and absorbed by the range hood. This prevents a large amount of smoke from remaining in the inner pot 21 at the end of cooking, preventing smoke from being directly sprayed onto the user when the door is opened after cooking. Furthermore, when the temperature of the inner pot 21 needs to be quickly lowered after cooking, cold air is introduced into the inner pot 21 through the above process, thereby achieving rapid cooling of the inner pot 21.
