[0006] In the above-mentioned cooking device, during the cooking process, the first heating element is controlled to stop working to prevent the gas temperature discharged from the air guide outlet from being too high and causing danger. After cooking, the first heating element is controlled to work to dry the condensed water generated in the exhaust chamber and the air guide chamber to prevent the exhaust chamber and the air guide chamber from being in a humid state for a long time, which may cause mold, taste change, etc. in the exhaust chamber and the air guide chamber. In addition, since the air guide chamber is farther away from the cooking chamber than the exhaust chamber, the gas temperature in the air guide chamber is lower than the gas temperature in the exhaust chamber, and condensed water is relatively easy to generate. Therefore, arranging the first heating element in the exhaust chamber can also prevent the condensed water generated in the air guide chamber from affecting the normal operation of the first heating element.

[0007] In one of the embodiments, the exhaust component further includes a first fan blade disposed in the exhaust cavity, and the first fan blade is capable of rotating relative to the exhaust member to drive the air in the exhaust cavity to flow toward the air outlet.

[0008] With such a configuration, the first fan blade can increase the gas flow rate in the exhaust chamber and the wind guide chamber, and can also cool the gas in the exhaust chamber and the wind guide chamber; arranging the first fan blade in the exhaust chamber can prevent condensation water generated in the wind guide chamber from affecting the normal operation of the first fan blade.

[0014] With such arrangement, the first fan blade cooperates with the output shaft in a simple manner, so as to facilitate controlling the first fan blade to start or stop working.

[0015] In one embodiment, the exhaust component also includes a sliding member and an elastic member. The sliding member is disposed in the exhaust chamber and can slide axially relative to the exhaust member along the output shaft. The sliding member abuts against one end of the first fan blade; the two ends of the elastic member respectively abut against one end of the first fan blade away from the sliding member and the exhaust member.

[0018] With this arrangement, only when the baking tray is pushed into the cooking cavity can the first transmission assembly and the second transmission assembly drive the sliding member to slide, so that the first fan blade slides to a position that cooperates with the transmission section, so that the output shaft can drive the first fan blade to rotate.

[0019] In one embodiment, a plurality of supporting ribs are provided on the inner wall of the inner pot along the height direction of the inner pot, and the supporting ribs are used to support the baking tray; the number of the first gear and the second gear are both multiple, and are arranged one-to-one corresponding to the supporting ribs, and the first transmission assembly also includes a second rack, which is provided outside the inner pot and can slide relative to the inner pot, the second rack is meshed with multiple second gears, and the second transmission assembly cooperates with any second gear.

[0047] Existing cooking equipment such as steam ovens are usually equipped with an exhaust system for exhausting the gas in the cooking cavity to the outside, and a fan is installed in the exhaust system. When the steaming function is working, condensed water is easy to be generated in the exhaust system, resulting in water droplets easily dripping at the exhaust outlet. In addition, the exhaust system is in a humid state for a long time, and it is easy to mold and change the taste, which affects the normal operation of the fan.

[0048] In order to solve the above problems, Figures 1 to 9 As shown, the present invention provides a cooking device to prevent condensation water from being generated in an air guide.

[0049] like Figure 1 and Figure 8 As shown, specifically, the cooking device includes an inner pot 1, an air guide member 2 and an exhaust assembly 3, wherein: the inner pot 1 is provided with a cooking cavity 11; the air guide member 2 is arranged outside the inner pot 1, and the air guide member 2 is provided with an air guide cavity (not shown) and an air guide inlet 21 and an air guide outlet 22 connected to the air guide cavity; the exhaust assembly 3 is arranged outside the inner pot 1, and includes an exhaust member 31 and a first heating member 32, the exhaust member 31 is provided with an exhaust cavity 311 and a first air inlet 312 and an air outlet 313 connected to the exhaust cavity 311, the first air inlet 312 is connected to the cooking cavity 11, the air outlet 313 is connected to the air guide inlet 21, and the first heating member 32 is arranged in the exhaust cavity 311.

[0050] In the cooking device provided by the embodiment of the present invention, the gas in the cooking cavity 11 can be discharged to the outside through the first air inlet 312, the exhaust cavity 311, the air outlet 313, the air guide inlet 21, the air guide cavity and the air guide outlet 22 in sequence; during the cooking process, the first heating element 32 is controlled to stop working to prevent the gas discharged from the air guide outlet 22 from having a dangerous temperature due to being too high; after the cooking is finished, the first heating element 32 is controlled to work to dry the condensed water generated in the exhaust cavity 311 and the air guide cavity to prevent the exhaust cavity 311 and the air guide cavity from being in a humid state for a long time, which causes the exhaust cavity 311 and the air guide cavity to become moldy or change taste; and because the air guide cavity is farther away from the cooking cavity 11 than the exhaust cavity 311, the gas temperature in the air guide cavity is lower than the gas temperature in the exhaust cavity 311, and condensed water is relatively easy to be generated. Therefore, arranging the first heating element 32 in the exhaust cavity 311 can also prevent the condensed water generated in the air guide cavity from affecting the normal operation of the first heating element 32.

[0051] like Figure 3 As shown, the exhaust assembly 3 further includes an exhaust pipe 38 , and two ends of the exhaust pipe 38 are respectively connected to the air outlet 313 and the air guide inlet 21 .

[0052] like Figure 1 to Figure 2As shown, in one embodiment, the air guide member 2 is arranged at the bottom of the inner pot 1. The air guide member 2 can utilize the original space at the bottom of the inner pot 1 to avoid increasing the overall volume of the cooking device. Specifically, the air guide member 2 and the mounting plate (not shown) at the bottom of the inner pot 1 can be arranged to form an air guide cavity, or a separate air guide cavity can be opened in the air guide member 2. Of course, in other embodiments, the air guide member 2 can also be arranged at the top of the inner pot 1 or at other positions, as long as the gas in the cooking cavity 11 can be discharged to the outside, and the embodiment of the present invention is not specifically limited here.

[0053] like Figure 3 to Figure 4 As shown, the exhaust component 3 also includes a first blade 33 disposed in the exhaust cavity 311. The first blade 33 can rotate relative to the exhaust component 31 to drive the air in the exhaust cavity 311 to flow toward the air outlet 313. The first blade 33 can increase the gas flow rate in the exhaust cavity 311 and the air guide cavity, and accelerate the gas discharge rate in the cooking cavity 11. At the same time, the first blade 33 can also cool the gas in the exhaust cavity 311 and the air guide cavity to prevent the gas temperature discharged from the air guide outlet 22 from being too high and causing danger. In addition, arranging the first blade 33 in the exhaust cavity 311 can also prevent the condensed water generated in the air guide cavity from affecting the normal operation of the first blade 33. Specifically, the first fan blade 33 can be controlled to work or stop working according to user needs or program settings. For example, during the steaming function cooking process, in order to prevent the loss of steam in the cooking cavity 11, the first fan blade 33 can be controlled to stop working; during the baking function cooking process, in order to reduce the humidity in the cooking cavity 11, or to reduce the temperature of the gas discharged from the air guide outlet 22, the first fan blade 33 can be controlled to work.

[0054] like Figure 6 and Figure 8 As shown, the first heating element 32 can be configured as an annular heating tube, which surrounds the outer circumference of the first fan blade 33 to increase the contact area between the first heating element 32 and the gas in the exhaust cavity 311, thereby enhancing the heating effect of the first heating element 32 on the gas in the exhaust cavity 311 and the wind guide cavity.

[0055] like Figure 3 and Figure 8As shown, the exhaust member 31 is further provided with a second air inlet 314 communicating with the exhaust cavity 311, and the exhaust assembly 3 further comprises a cover 36, which is openably and closably provided to cover the second air inlet 314. When the cover 36 opens the second air inlet 314, external air can enter the exhaust cavity 311 through the second air inlet 314 and mix with the air entering the exhaust cavity 311 from the cooking cavity 11, so as to reduce the temperature of the air in the exhaust cavity 311 and the air guide cavity, and prevent the temperature of the gas discharged from the air guide outlet 22 from being too high and causing danger. Specifically, the cover 36 can be controlled to open or close the second air inlet 314 according to user needs or program settings. For example, during the cooking process of the grilling function, since the temperature of the gas entering the exhaust cavity 311 from the cooking cavity 11 is relatively high, the cover 36 can be controlled to open the second air inlet 314; after the cooking is finished, when the first heating element 32 is controlled to work, the cover 36 can be controlled to close the second air inlet 314 to prevent the outside air from entering the exhaust cavity 311 and the wind guide cavity from the second air inlet 314, thereby affecting the drying effect of the condensed water in the exhaust cavity 311 and the wind guide cavity. In addition, when the cover 36 opens the second air inlet 314, the first fan blade 33 can also be controlled to work at the same time. The operation of the first fan blade 33 can make the exhaust cavity 311 in a negative pressure state, so as to accelerate the rate at which the outside air enters the exhaust cavity 311 from the second air inlet 314.

[0056] like Figure 3 to Figure 4 As shown, the cross-sectional area of ​​the second air inlet 314 is more than four times the cross-sectional area of ​​the first air inlet 312. The second air inlet 314 has a larger cross-sectional area, so that the gas temperature in the exhaust cavity 311 and the wind guide cavity can be quickly reduced, thereby quickly reducing the gas temperature discharged from the wind guide outlet 22.

[0057] like Figure 3 As shown, in one embodiment, the cover 36 is arranged on the exhaust member 31 and can rotate relative to the exhaust member 31 to open or cover the second air inlet 314, and the exhaust assembly 3 also includes a second driving member 37 for driving the cover 36 to rotate. Specifically, the second driving member 37 includes a first motor 371 and a first rotating shaft 372, and the cover 36 is connected to the first rotating shaft 372. The first motor 371 can drive the first rotating shaft 372 to reciprocate around its own axis, thereby driving the cover 36 to reciprocate to open or cover the second air inlet 314. The opening and closing method of the cover 36 is simple, easy to control, and occupies less space. Of course, in other embodiments, the cover 36 can also achieve punching or covering the second air inlet 314 by other motion methods such as sliding relative to the exhaust member 31, and the embodiment of the present invention is not specifically limited here.

[0058] Furthermore, the exhaust assembly 3 further includes a sealing member (not shown) disposed between the cover 36 and the exhaust member 31, and the sealing member is located at the periphery of the second air inlet 314. The sealing member can ensure the sealing between the cover 36 and the exhaust member 31 when the second air inlet 314 is closed, and prevents external gas from entering the exhaust cavity 311 through the gap between the cover 36 and the exhaust member 31 and affecting the normal operation of the exhaust assembly 3. Specifically, at least one of the cover 36 and the exhaust member 31 is provided with a sealing groove for installing the sealing member, and the sealing groove is located at the periphery of the second air inlet 314.

[0059] like Figure 1 and Figure 8 As shown, the cooking device further includes a hot air component 4 disposed at the rear side of the inner pot 1, the hot air component 4 is provided with a hot air cavity 41 connected with the cooking cavity 11, and the hot air component 4 includes a second fan blade 42, and the second fan blade 42 is rotatably disposed in the hot air cavity 41. Specifically, the inner pot 1 further includes a first baffle 13 disposed between the cooking cavity 11 and the hot air cavity 41, and a connecting port 131 for connecting the cooking cavity 11 and the hot air cavity 41 is opened on the first baffle 13, part of the connecting port 131 is used as an air inlet, and part of the connecting port 131 is used as an air outlet. When the second fan blade 42 is working, the gas in the cooking cavity 11 can enter the hot air cavity 41 through the air inlet, and at least part of the gas in the hot air cavity 41 can return to the cooking cavity 11 through the air outlet, so as to realize the circulation of the gas in the cooking cavity 11 and improve the uniformity of the temperature in the cooking cavity 11.

[0060] like Figure 6 and Figure 8 As shown, the hot air assembly 4 also includes a second heating element 45, which can be configured as an annular heating tube that surrounds the outer circumference of the second fan blade 42 to perform secondary heating on the gas around the second fan blade 42, thereby increasing the temperature of the gas returning to the cooking cavity 11 through the air outlet, thereby further improving the uniformity of the temperature in the cooking cavity 11.

[0061] like Figure 3 and Figure 8As shown, in one embodiment, the exhaust assembly 3 is arranged at the rear side of the inner liner 1, and the hot air assembly 4 also includes a first driving member 43 and an output shaft 44. The first driving member 43 is arranged on the side of the exhaust member 31 away from the inner liner 1, and the output shaft 44 passes through the first driving member 43 and is connected to the first blade 33 and the second blade 42. The first driving member 43 can drive the output shaft 44 to rotate around its own axis, so as to drive the first blade 33 and the second blade 42 to rotate together. The first blade 33 and the second blade 42 share a driving element, which can reduce the number of parts and reduce the occupied space. In addition, the first driving member 43 is arranged on the side of the exhaust member 31 away from the inner liner 1, so that the first driving member 43 is far away from the inner liner 1, thereby reducing the ambient temperature of the first driving member 43, and ensuring that the first driving member 43 can work normally. Of course, in other embodiments, the exhaust component 3 can also be arranged at other positions of the inner tank 1, and the exhaust component 3 also includes a third driving member (not shown), and the third driving member can drive the first fan blade 33 to rotate relative to the exhaust member 31, that is, the second fan blade 42 and the first fan blade 33 are independently driven by the first driving member 43 and the third driving member respectively.

[0062] like Figure 3 to Figure 4 As shown, in one embodiment, the first air inlet 312 is provided on a side wall of the exhaust member 31 facing the inner pot 1, and the first air inlet 312 is connected to the cooking cavity 11 through the hot air cavity 41. Specifically, the inner pot 1 further includes a second baffle 14 provided at the rear side of the first baffle 13 and enclosed with the first baffle 13 to form the hot air cavity 41. The exhaust cavity 311 can be formed by the exhaust member 31 and the second baffle 14, and the first air inlet 312 is provided on the second baffle 14; or, the exhaust cavity 311 can be separately provided in the exhaust member 31, and the first air inlet 312 can be correspondingly provided on the second baffle 14 and the exhaust member 31. In this way, the gas in the cooking cavity 11 can enter the hot air cavity 41 through the air inlet, and part of the gas in the hot air cavity 41 can enter the exhaust cavity 311 through the first air inlet 312. In addition, the exhaust assembly 3 and the hot air assembly 4 have simple structures, which are convenient for processing and assembly. Of course, in other embodiments, the first air inlet 312 may also be connected to the cooking cavity 11 through an air inlet pipe (not shown).

[0063] like Figure 6 and Figure 8As shown, in one embodiment, the second fan blade 42 includes a first blade 421 and a second blade 422 which are separated from each other, the first blade 421 faces the inner pot 1, and can drive the air in the hot air cavity 41 to flow toward the cooking cavity 11, and the second blade 422 faces the exhaust member 31, and can drive the air in the hot air cavity 41 to flow toward the first air inlet 312. The first blade 421 is used to blow part of the gas in the hot air cavity 41 into the cooking cavity 11 to achieve the circulation of the gas in the cooking cavity 11, and the second blade 422 is used to blow part of the gas in the hot air cavity 41 into the exhaust cavity 311 through the first air inlet 312. Of course, in other embodiments, the second fan blade 42 may also include only the first blade 421.

[0064] like Figures 8 to 9 As shown, along the axial direction of the output shaft 44, the output shaft 44 includes a transmission section 441 and a disengagement section 442, and the first blade 33 can slide along the axial direction of the output shaft 44 to cooperate with the transmission section 441 or the disengagement section 442; when the first blade 33 cooperates with the transmission section 441, the first blade 33 rotates together with the output shaft 44, and when the first blade 33 cooperates with the disengagement section 442, the first blade 33 stops rotating. When it is necessary to control the first blade 33 to work, the first blade 33 is controlled to slide along the axial direction of the output shaft 44 to a position that cooperates with the transmission section 441. At this time, when the first driving member 43 drives the output shaft 44 to rotate, the output shaft 44 can drive the first blade 33 and the second blade 42 to rotate together; when it is necessary to control the first blade 33 to stop working, the first blade 33 is controlled to slide in the opposite direction along the axial direction of the output shaft 44 to a position that cooperates with the disengagement section 442. At this time, when the first driving member 43 drives the output shaft 44 to rotate, the output shaft 44 can only drive the second blade 42 to rotate alone. The first fan blade 33 cooperates with the output shaft 44 in a simple manner, so as to facilitate controlling the first fan blade 33 to work or stop working.

[0065] like Fig. 9 As shown, in one embodiment, the outer diameter of the transmission section 441 is equal to the inner diameter of the first blade 33, so that when the first blade 33 cooperates with the transmission section 441, the transmission section 441 can drive the first blade 33 to rotate together; the outer diameter of the disengagement section 442 is smaller than the inner diameter of the first blade 33, so that the disengagement section 442 can rotate independently relative to the first blade 33. Of course, in other embodiments, the transmission section 441 and the first blade 33 can also cooperate through other structures such as a non-rotating body cross-section, as long as the transmission section 441 can drive the first blade 33 to rotate together, and the embodiment of the present invention does not make specific restrictions here.

[0066] like Figure 7 and Fig. 9As shown, the exhaust assembly 3 also includes a sliding member 34 and an elastic member 35. The sliding member 34 is arranged in the exhaust cavity 311 and can slide relative to the exhaust member 31 along the axial direction of the output shaft 44. The sliding member 34 abuts against one end of the first blade 33; the two ends of the elastic member 35 respectively abut against one end of the first blade 33 away from the sliding member 34 and the exhaust member 31. When the first blade 33 cooperates with the transmission section 441, the elastic member 35 is compressed. When it is necessary to control the first blade 33 to work, the sliding member 34 is controlled to slide along the axial direction of the output shaft 44. The sliding member 34 can push the first blade 33 to slide along the axial direction of the output shaft 44 to a position that cooperates with the transmission section 441, and the elastic member 35 is compressed; when it is necessary to control the first blade 33 to stop working, the sliding member 34 is controlled to slide in the opposite direction along the axial direction of the output shaft 44. The first blade 33 can slide in the opposite direction along the axial direction of the output shaft 44 under the action of the elastic force of the elastic member 35 to a position that cooperates with the disengagement section 442. Therefore, the sliding member 34 and the elastic member 35 can control the axial sliding of the first blade 33 along the output shaft 44, and the normal rotation of the first blade 33 can be ensured.

[0067] like Figure 7 As shown, the exhaust component 3 also includes a first limiting member 342 fixedly disposed in the exhaust chamber 311, and the sliding member 34 is provided with a first limiting groove 341 extending axially along the output shaft 44, and the first limiting member 342 can be slidably disposed in the first limiting groove 341 to limit the sliding direction of the sliding member 34.

[0068] like Figure 2 , Figure 5 and Figure 7 As shown, in one embodiment, the cooking device further includes a first transmission assembly 5 and a second transmission assembly 6. The first transmission assembly 5 includes a first gear 51, a second gear 52 and a first rack 53. The first gear 51 and the second gear 52 are respectively arranged in the cooking cavity 11 and outside the inner pot 1, and can rotate relative to the inner pot 1 together. The first rack 53 is used to be arranged on the baking tray 7. When the baking tray 7 is pushed into or pulled out of the cooking cavity 11, the first rack 53 can mesh with the first gear 51. The two ends of the second transmission assembly 6 are respectively matched with the second gear 52 and the sliding member 34. When the second gear 52 rotates, the second transmission assembly 6 can drive the sliding member 34 to slide. Specifically, the first transmission assembly 5 also includes a second rotating shaft 55. The second rotating shaft 55 is rotatably arranged on the side wall of the inner pot 1. The first gear 51 and the second gear 52 are respectively connected to the inner and outer ends of the second rotating shaft 55. The first transmission assembly 5 also includes a second limiting member 56 fixedly arranged on the outer wall of the inner container 1. The second rack 54 is provided with a second limiting groove 541 extending along the length direction. The second limiting member 56 is slidably arranged in the second limiting groove 541 to limit the sliding direction of the second rack 54.

[0069] Before cooking with the grilling function, place food on the grilling tray 7 and push the grilling tray 7 into the cooking cavity 11, the first rack 53 on the grilling tray 7 meshes with the first gear 51 and drives the first gear 51 to rotate, the first gear 51 drives the second gear 52 to rotate together, the second gear 52 drives the sliding member 34 to slide along the axial direction of the output shaft 44 through the second transmission assembly 6, the sliding member 34 pushes the first fan blade 33 to slide along the axial direction of the output shaft 44 to a position matched with the transmission section 441; after cooking with the grilling function is finished, the grilling tray 7 is pulled out of the cooking cavity 11, the first rack 53 drives the first gear 51 to rotate in the opposite direction, the first gear 51 drives the second gear 52 to rotate in the opposite direction together, the second gear 52 drives the sliding member 34 to slide in the opposite direction along the axial direction of the output shaft 44 through the second transmission assembly 6, the sliding member 34 pushes the first fan blade 33 to slide in the opposite direction along the axial direction of the output shaft 44 to a position matched with the disengagement section 442. During the steaming cooking process, the food is placed on the steaming plate (not shown). Since the first rack 53 is not provided on the steaming plate, when the steaming plate is pushed into or pulled out of the cooking cavity 11, the first gear 51 will not be driven to rotate, and the first blade 33 is always in a position to cooperate with the disengagement section 442. In this way, only when the baking tray 7 is pushed into the cooking cavity 11, the first transmission assembly 5 and the second transmission assembly 6 can drive the sliding member 34 to slide, so that the first blade 33 slides to a position to cooperate with the transmission section 441, so that the output shaft 44 can drive the first blade 33 to rotate, and the user can choose to use the baking tray 7 or the steaming plate according to actual needs. It should be noted that if the first blade 33 needs to be controlled to work during the steaming cooking process, the first rack 53 can also be installed on the steaming plate accordingly; similarly, if the first blade 33 needs to be controlled to stop working during the baking cooking process, the first rack 53 can also be removed from the baking tray 7.

[0070] Of course, in other embodiments, the exhaust assembly 3 may further include a fourth drive member (not shown), which can directly drive the first fan blade 33 to slide axially along the output shaft 44, that is, the first fan blade 33 is not driven to slide by pushing in or pulling out the baking tray 7.

The baking tray 7 is mounted on the support rib 12 at any height, and the first rack 53 on the baking tray 7 can mesh with the corresponding first gear 51 and drive the first gear 51 to rotate, the first gear 51 drives the corresponding second gear 52 to rotate, the second gear 52 drives the second rack 54 to slide, the second rack 54 drives all the second gears 52 to rotate synchronously, and the second transmission assembly 6 drives the sliding member 34 to slide. Of course, in other embodiments, the corresponding first gear 51 and the second gear 52 may be provided only at some of the support ribs 12. Only when the baking tray 7 is mounted on the support rib 12 with the first gear 51 and the second gear 52, the first fan blade 33 will work. The user can mount the baking tray 7 on different support ribs 12 according to actual needs.
