[0052] The cooking appliance is equipped with an air inlet, an exhaust duct, and a heat dissipation fan. A portion of the heat dissipation fan's airflow is used to dissipate heat during cooking, discharging excess high-temperature steam from the cooking cavity into the exhaust duct. Another portion of the heat dissipation fan's airflow is used to exhaust the high-temperature steam after cooking. Specifically, the airflow enters the cooking cavity through the air inlet and squeezes out the high-temperature steam. However, the airflow from the air inlet is uncontrollable, making it difficult to adjust the airflow required for the heat dissipation and exhaust processes based on actual needs. This results in low heat dissipation and exhaust efficiencies.

[0053] In response to the above technical problems, an embodiment of the present application provides a cooking appliance that can better control the air intake volume of the air inlet interface, which helps to ensure that the air inlet interface is exposed during the rapid steam exhaust process so that the air inlet interface has sufficient air intake volume, and hides the air inlet interface when steam exhaust is not performed, so as to reduce the impact on the normal air duct steam exhaust and heat dissipation, thereby being able to adjust the heat dissipation process and the air intake volume required for the steam exhaust process according to actual needs, thereby maximizing the heat dissipation efficiency and steam exhaust efficiency.

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a cooking appliance 100 , which includes a box body and a shell. The box body is accommodated in the shell, and the box body has a cooking cavity 110 .

[0056] In the embodiment of the present application, there is no limitation on the type of the cooking appliance 100. For example, the cooking appliance 100 of this embodiment can be an oven, a steamer, a steam-bake combination machine, or a steam-bake mini combination machine. In this embodiment, the cooking appliance 100 is mainly described as a steam-bake combination machine.

[0057] A steam-bake combination integrates the functions of a gas stove, steamer, and oven. Because one appliance is equivalent to multiple independent kitchen appliances, it can simultaneously fry / stew and steam / bake, freeing up kitchen space. The appliance's heating system converts water into steam, which is then used to steam, bake, and cook food.

[0058] It should be noted that the box body in this embodiment is the inner pot of the cooking utensil 100, and the cooking cavity 110 is formed in the inner pot. The inner pot is one of the core components of the steam-bake combination machine, and the inner pot is used to cook food. Among them, there is no limitation on the material of the inner pot. For example, the material of the inner pot can be stainless steel, and the stainless steel inner pot can withstand higher temperature water and detergent. At the same time, stainless steel has antibacterial properties and is easy to clean; or, the material of the inner pot can be plastic, and the plastic inner pot has certain impact resistance and electrical insulation properties; or, the material of the inner pot can be ceramic, which has the advantages of being smooth, slowly deteriorating, and corrosion-resistant, and can also increase the washing effect. This embodiment does not limit this.

[0059] In the present application, refer to Figures 1 to 3 As shown, the cooking appliance 100 includes a steam exhaust component 120 and an air intake component 130, and the steam exhaust component 120 and the air intake component 130 are arranged on a box body.

[0060] For example, the exhaust assembly 120 and the air inlet assembly 130 can be arranged outside the box. This, on the one hand, can ensure the cleanliness of the box interior, reduce the complexity of the internal structure, and make cleaning more convenient; on the other hand, this arrangement is conducive to the effective use of steam and the heat dissipation of the equipment; and still another aspect is that by placing both the exhaust assembly 120 and the air inlet assembly 130 outside the box, the heat exchange process can be better controlled, which not only reduces energy consumption but also helps to reduce operating costs.

[0061] In the present application, refer to Figure 1 and Figure 3 As shown, the exhaust component 120 may include an exhaust fan 121 and an air duct housing 122, the air duct housing 122 has an exhaust duct 124 inside, the exhaust duct 124 has an exhaust end connected to the external environment of the cooking appliance and a steam inlet end connected to the cooking cavity 110; and the exhaust fan 121 is configured to blow air into the exhaust duct 124; the air inlet component 130 is connected to the cooking cavity 110 to promote steam to flow from the steam inlet end of the exhaust duct 124 to the exhaust end; the air inlet component 130 includes an air inlet housing 131, and the air inlet housing 131 has an air inlet interface 133.

[0062] The exhaust fan 121 dissipates heat as follows: During cooking, steam generated in the steam generating pipe enters the cooking cavity 110 to heat the food. Excess steam flows through the exhaust pipe and enters the exhaust duct 124. The exhaust fan 121 then blows air into the exhaust duct 124, discharging the steam outside the cooking appliance 100. Furthermore, the exhaust fan 121 dissipates heat from the top of the inner pot through the exhaust duct 124. This effectively dissipates heat from the electrical components, keeping them within a stable temperature range, ensuring proper operation of the electrical components and the cooking appliance 100, and preventing damage to the electrical components.

[0063] For example, the heat dissipation path of the exhaust fan 121 can refer to Figure 3 and Figure 5 As shown in the direction of arrow a.

[0064] The exhaust path of the exhaust fan 121 is as follows: after the cooking appliance 100 finishes cooking, a part of the air flow blown out by the exhaust fan 121 is diverted to the air inlet channel, and enters the cooking cavity 110 through the air inlet channel, and squeezes the high-temperature steam inside the cooking cavity 110 into the exhaust pipe, and then enters the exhaust duct 124 through the exhaust pipe. The exhaust fan 121 discharges the high-temperature steam in the exhaust duct 124 to the outside of the cooking appliance 100.

[0065] For example, the exhaust path of the exhaust fan 121 can refer to Figure 3 and Figure 5 As shown in the direction of arrow b.

[0066] It can be understood that, in this embodiment, the heat dissipation of the exhaust fan 121 is performed during the cooking process, and the exhaust of the exhaust fan 121 is performed after the cooking is completed.

[0067] In the present application, refer to Figure 1 and Figure 2 As shown, the cooking appliance 100 includes a panel 140 connected to the housing. Panel 140 is provided with a steam exhaust port 141, which is communicated with the steam exhaust duct 124. In this embodiment, the high-temperature steam within the steam exhaust duct 124 is primarily discharged from the cooking appliance 100 through the steam exhaust port 141. This helps ensure that the steam and hot air generated during cooking are quickly discharged, preventing the internal temperature of the cooking appliance 100 from overheating. Furthermore, the location of the steam exhaust port 141 on the panel 140 facilitates regular cleaning and maintenance, reduces grease accumulation, and keeps the cooking appliance 100 clean and hygienic.

[0068] In order to adjust the air volume of the air inlet interface 133, the air volume required for the heat dissipation process and the exhaust process can be adjusted according to actual needs. Figures 2 to 5As shown, the air inlet assembly 130 may also include a driving mechanism 136, which is arranged in the air duct shell 122. The output end of the driving mechanism 136 is connected to the air inlet shell 131, and can drive at least part of the structure of the air inlet shell 131 to move relative to the air duct shell 122, so that the air inlet interface 133 enters the exhaust air duct 124 and is connected to the exhaust air duct 124, or, the air inlet interface 133 exits from the exhaust air duct 124 and is disconnected from the exhaust air duct 124.

[0069] In the embodiment of the present application, there is no limitation on the connection method between the driving mechanism 136 and the air duct housing 122, and between the output end of the driving mechanism 136 and the air inlet housing 131, and specific settings can be made according to actual needs.

[0070] For example, during the steam exhaust process, the air inlet port 133 needs to be exposed to ensure that a portion of the airflow from the heat dissipation fan can be blown into the air inlet port 133 and into the cooking cavity 110 through the air inlet port 133, thereby squeezing out the high-temperature steam in the cooking cavity 110. At this time, the drive mechanism 136 can drive at least a portion of the air inlet housing 131 to rise, allowing the air inlet port 133 to enter the exhaust duct 124 and communicate with the exhaust duct 124, thereby maximizing the amount of air intake during rapid steam exhaust and improving exhaust efficiency.

[0071] in, Figure 2 and Figure 3 The air inlet port 133 enters the exhaust air duct 124 and is connected to the exhaust air duct 124. Figure 3 The wind flows in the direction of arrow a, and part of the wind flows along Figure 3 Flows in the direction of arrow b.

[0072] For example, during the heat dissipation process, when steam exhaust is not required, the air inlet port 133 needs to be hidden to ensure that the airflow from the heat dissipation fan is fully utilized for heat dissipation, thereby reducing the impact of air entering the air inlet port 133 on normal air duct exhaust and heat dissipation. In this case, the drive mechanism 136 can drive at least a portion of the structure of the air inlet housing 131 to move downward, disconnecting the air inlet port 133 from the exhaust duct 124. The air inlet port 133 is hidden, thereby helping to reduce the impact on normal air duct exhaust and heat dissipation.

[0073] For example, Figure 4 and Figure 5 The air inlet port 133 is a schematic diagram of the structure of exiting from the exhaust air duct 124 and disconnecting from the exhaust air duct 124. In the above embodiment, the air flow of the exhaust fan 121 is all along the Figure 5 Flows in the direction of arrow a.

[0074] Therefore, the cooking appliance 100 provided in the present application can better control the air intake volume of the air inlet interface 133, which helps to ensure that the air inlet interface 133 is exposed during the rapid steam exhaust process so that the air inlet interface 133 has sufficient air intake volume, and hides the air inlet interface 133 when steam exhaust is not performed, so as to reduce the impact on the normal air duct steam exhaust and heat dissipation, thereby being able to adjust the heat dissipation process and the air intake volume required for the steam exhaust process according to actual needs, thereby maximizing the heat dissipation efficiency and steam exhaust efficiency.

[0075] In one possible implementation, referring to Figure 3 As shown, the bottom wall of the exhaust duct 124 may be provided with an opening 1223 that communicates with the cooking cavity 110, with the air inlet housing 131 facing the opening 1223. The drive mechanism 136 is configured to drive the air inlet housing 131 to rise and fall relative to the air duct housing 122, thereby inserting the air into the exhaust duct 124 through the opening 1223, allowing a portion of the airflow from the exhaust fan 121 to enter the cooking cavity 110 through the air inlet housing 131; or to withdraw the airflow from the opening 1223, thereby disconnecting the airflow between the exhaust fan 121 and the cooking cavity 110.

[0076] The circumferential contour of the air inlet housing 131 matches the shape of the opening 1223 ; and when the air inlet housing 131 moves relative to the air duct housing 122 , the outer wall of the air inlet housing 131 is in sliding contact with at least part of the inner edge of the opening 1223 .

[0077] In this embodiment, the shape of the opening 1223 is not limited and can be configured according to the shapes of the air inlet housing 131 and the exhaust duct 124. For example, the shape of the opening 1223 can be circular or square, which is not limited in this embodiment. Furthermore, the size of the opening 1223 is also not limited.

[0078] In the embodiment of the present application, the circumferential profile of the air inlet housing 131 matches the shape of the opening 1223; the drive mechanism 136 is configured to drive the air inlet housing 131 to be inserted into the exhaust duct 124 through the opening 1223, or to be withdrawn from the opening 1223. Thus, due to the consistency of the circumferential profile, the air inlet housing 131 can move more smoothly, helping to reduce friction and resistance caused by the shape difference, thereby ensuring the movement stability of the air inlet housing 131.

[0079] In one possible implementation, referring to Figure 3 and Figure 3 As shown, the air inlet shell 131 may include an air inlet base 1311 and an air inlet cover 1312 connected to the top of the output end of the driving mechanism 136. The air inlet cover 1312 and the air inlet base 1311 are arranged to form an air inlet cavity 135 connected to the air inlet interface 133. The air inlet interface 133 is arranged on the air inlet cover 1312.

[0080] For example, there is no limitation on the arrangement of the air inlet base 1311 and the air inlet cover 1312. For example, the air inlet cover 1312 can cover the air inlet base 1311, wherein the outer periphery of the air inlet base 1311 on the side away from the air inlet port 133 can be blocked outside the air inlet cover 1312. This helps to improve the sealing performance of the air inlet cavity 135, reduce air leakage, and improve the utilization rate of the airflow.

[0081] In the embodiment of the present application, the air inlet base 1311 can be disposed outside the air duct housing 122, with an opening 1223 formed in the air duct housing 122; the air inlet cover 1312 is opposite the opening 1223 and is movable relative to the air inlet base 1311; and the output end of the drive mechanism 136 is connected to the air inlet cover 1312. It will be appreciated that the air inlet cover 1312 and the air inlet base 1311 are separate structures, which helps ensure that the air inlet cover 1312 can move relative to the air inlet base 1311.

[0082] It should be noted that the air inlet base 1311 and the air inlet cover 1312 are set separately, and the position of the air inlet base 1311 does not change when the air inlet cover 1312 is moved. In this way, while the air inlet cover 1312 is moved relative to the air inlet base 1311, it will not affect the connection with the air inlet pipe, which helps to ensure that the airflow can smoothly enter the air inlet pipe during the exhaust process.

[0083] In one possible implementation, the projection shape of the air inlet cover 1312 in its moving direction matches the shape of the opening 1223. The moving direction of the air inlet cover 1312 is not limited. In this embodiment, the example of the air inlet cover 1312 moving up and down relative to the air base is mainly used for description.

[0084] The air inlet base 1311 has a connecting wall connected to the lower edge of the opening 1223 in the circumferential direction, and the outer wall surface of the air inlet cover plate 1312 and the inner wall surface of the connecting wall at least partially overlap.

[0085] Specifically, when the exhaust state needs to be turned on, the driving mechanism 136 pulls up the air inlet cover 1312 to expose the air inlet structure, so that air can smoothly enter the cooking cavity 110 from the air inlet interface 133 and squeeze out the high-temperature steam in the cooking cavity 110.

[0086] Specifically, when the exhaust state needs to be turned off after cooking is finished, the driving mechanism 136 puts the air inlet cover 1312 back, and the air inlet cover 1312 and the air inlet base 1311 are on the same plane, so that it does not hinder the wind from exhausting the high-temperature steam from the cooking cavity 110, and quickly discharges the high-temperature steam in the exhaust duct 124 to the outside to avoid its impact on electrical components.

[0087] In the embodiment of the present application, the projection shape of the air inlet cover 1312 in its moving direction matches the shape of the opening 1223. This allows the air inlet cover 1312 to move more smoothly, helps reduce friction and resistance caused by the shape difference, and thus ensures the movement stability of the air inlet cover 1312.

[0088] In one possible implementation, referring to Figure 3 As shown, the air inlet interface 133 can be located on the side of the air inlet cover 1312 , and the air inlet interface 133 can be set toward the air outlet side of the exhaust fan 121 .

[0089] In the present embodiment, the shape of the air inlet port 133 is not limited and can be configured based on the specific design of the exhaust fan 121 and exhaust duct 124 and actual needs. For example, the shape of the air inlet port 133 can be circular or square. This is not limited in the present embodiment. Furthermore, the size of the air inlet port 133 is also not limited.

[0090] In the embodiment of the present application, the air inlet port 133 is located to the side of the air inlet cover 1312. This design can effectively ensure sufficient airflow in the air inlet cavity 135 and ensure smooth exhaust. In addition, the side air inlet can reduce air loss during the transportation process and reduce airflow waste.

[0091] In the embodiment of the present application, the air inlet port 133 is oriented toward the outlet side of the exhaust fan 121. This, on the one hand, allows the airflow generated by the exhaust fan 121 to be utilized to drive the air intake, thereby reducing the energy required to independently drive the air intake. On the other hand, it ensures smooth airflow, avoids dead spots in the airflow, and improves the uniformity and efficiency of the air intake. Furthermore, it helps to simplify the design of the air intake system, reducing system complexity and maintenance costs.

[0092] In one possible implementation, referring to Figure 3 and Figure 5 As shown, an air guide wall 1313 may be provided on the side of the air inlet cover 1312 away from the air inlet port 133. The air guide wall 1313 may be arranged in an arc shape, slanting downward from the end adjacent to the air inlet port 133 to the end away from the air inlet port 133. This design, on the one hand, allows the curved air guide wall 1313 to change the direction and speed of air flow, thereby more effectively guiding the airflow in a predetermined direction. On the other hand, the curved air guide wall 1313 can more effectively distribute air, reducing dead angles and airflow obstructions, thereby improving airflow efficiency.

[0093] In order to further improve the sealing performance of the air inlet cover 1312 and the air inlet base 1311, in the embodiment of the present application, Figure 3 and Figure 5As shown, a shielding portion 1314 extending in the horizontal direction may be provided above the air guide wall 1313 , and when the air inlet port 133 exits from the exhaust air duct 124 , the edge of the shielding portion 1314 docks with the inner edge of the opening 1223 .

[0094] Exemplarily, the shielding portion 1314 can be a planar structure. In this way, when the air inlet interface 133 exits the exhaust duct 124, the shielding portion 1314 and the air inlet base 1311 are in the same plane, which can further effectively prevent the airflow from flowing out from the connection gap between the air inlet cover 1312 and the air inlet base 1311, thereby improving the sealing performance.

[0095] In one feasible embodiment, the air inlet assembly 130 further includes an air inlet duct 132, which is in communication with the air inlet housing 131. The air inlet direction of the air inlet duct 132 is opposite to the air inlet direction of the air inlet port 133. This prevents the airflow from entering the cooking cavity at too high a speed, and the kinetic energy of the airflow can be reduced by redirecting the airflow.

[0096] Reference Figure 1 As shown, the air inlet assembly 130 may also include an air inlet valve 134, the air inlet base 1311 is provided with a connecting joint 1315, the first end of the air inlet pipe 132 is connected to the connecting joint 1315, and the second end of the air inlet pipe 132 is connected to the cooking cavity 110; the air inlet valve 134 is arranged on the air inlet pipe 132, and the air inlet valve 134 is configured to control the on and off of the air inlet pipe 132.

[0097] In the embodiment of the present application, the air inlet valve 134 is closed during heat dissipation and opened during steam exhaust. This is because, during normal operation of the cooking appliance 100, part of the airflow in the exhaust duct 124 is diverted to the air inlet port 133. However, due to the action of the air inlet valve 134, the airflow does not directly enter the cooking cavity 110. When cooking is finished and the high-temperature steam in the cooking cavity 110 needs to be quickly exhausted, the air inlet valve 134 is opened. Air, under the action of the exhaust fan 121, enters the air inlet port 133, passes through the air inlet valve 134, and enters the cooking cavity 110, squeezing out the steam in the cooking cavity 110 and achieving rapid steam exhaust.

[0098] In addition, this setting ensures that even if the sealing ring of the air inlet valve 134 ages and produces a small amount of air leakage after long-term use, steam leaking into the exhaust duct 124 will be pushed back by the wind force of the exhaust fan 121, thereby ensuring that there will be no impact on electrical components.

[0099] In the embodiment of the present application, there is no limitation on the structure of the connecting joint 1315. For example, the shape of the connecting joint 1315 can be adapted to the shape of the air inlet pipe 132. For example, a portion of the outer wall of the connecting joint 1315 is embedded in the inner wall of the air inlet pipe 132. This helps to improve the connection stability between the connecting joint 1315 and the air inlet pipe 132, and improves the sealing performance, thereby reducing air leakage.

[0100] The structure of the driving mechanism 136 provided in this application is described in detail below.

[0101] In the first possible implementation, refer to Figure 3 and Figure 5 As shown, the driving mechanism 136 may include a driving unit 1361 and a driving rod 1362, the driving unit 1361 is arranged on the top outer side of the air duct shell 122; the first end of the driving rod 1362 is connected to the output end of the driving unit 1361; the second end of the driving rod 1362 passes through the top wall of the air duct shell 122 and is inserted into the interior of the exhaust air duct 124, and is connected to the air inlet shell 131.

[0102] In the embodiment of the present application, there is no limitation on the type of the driving mechanism 136. For example, the driving mechanism 136 may be an electric motor. This embodiment does not limit this.

[0103] In the embodiment of the present application, the drive unit 1361 is configured to drive the drive rod 1362 to move in a vertical direction, so that the drive rod 1362 drives the air inlet housing 131 to enter or exit the exhaust air duct 124. The driving method of the present application has a high degree of automation, can drive the air inlet housing 131 to maintain stable movement, and has the ability to respond quickly.

[0104] In a feasible embodiment, the second end of the driving rod 1362 may be provided with a first clamping portion, and the outer side of the top wall of the air inlet housing 131 may be provided with a second clamping portion, and the first clamping portion is clamped below the second clamping portion.

[0105] In the embodiment of the present application, the structures of the first and second engaging portions are not further limited. For example, the first engaging portion may be a protrusion, and the second engaging portion may be a slot, with the first engaging portion engaging the second engaging portion. This improves the stability of the connection between the drive rod 1362 and the air inlet housing 131 when the air inlet housing 131 is driven to move, reducing looseness during movement and thereby ensuring stable movement and normal use of the air inlet housing 131.

[0106] During the cooking process of food, such as the baking process of bread, the cooking cavity 110 is generally required to maintain an appropriate air intake volume to maintain different steam concentrations and improve the cooking effect of the food.

[0107] Therefore, in order to further adjust the air intake volume, in the embodiment of the present application, the second possible implementation method is to refer to Figure 6 and Figure 7 As shown, a driving mechanism 136 is also provided. The driving mechanism 136 may include a driving unit 1361, a gear 1363 and a rack 1364. The driving unit 1361 is arranged on the top outer side of the air duct shell 122; the gear 1363 is coaxially connected to the output end of the driving unit 1361; the rack 1364 is engaged with the gear 1363, and the rack 1364 passes through the top wall of the air duct shell 122 and is inserted into the interior of the exhaust air duct 124, and is connected to the air inlet shell 131.

[0108] In the embodiment of the present application, the type of the driving unit 1361 is not limited. For example, the driving unit 1361 in this embodiment can be a servo motor.

[0109] In the embodiment of the present application, the drive unit 1361 is configured to drive the gear 1363 to rotate, so that the gear 1363 drives the rack 1364 to move, and the rack 1364 then drives the air inlet housing 131 to enter or exit the exhaust air duct 124. The drive method of the present application has a high degree of automation, can drive the air inlet housing 131 to maintain stable movement, and has the ability to respond quickly.

[0110] It should be noted that the difference between the driving unit 1361 of this embodiment and the first embodiment is that in the first embodiment, the driving unit 1361 drives the driving rod 1362 to move up and down, and in this embodiment, under the action of the servo motor, the gear 1363 drives the rack 1364 to move up and down, wherein, under the action of the servo motor, hovering at any position can be achieved. Therefore, in this embodiment, the height of the air inlet interface 133 can be adjusted, so that the size of the air inlet interface 133 is adjustable, thereby ensuring that during the food cooking process, different air intake volumes are used to maintain different steam concentrations in the cavity, thereby improving the cooking effect of the food.

[0111] For example, refer to Figure 8 and Figure 9 As shown, during the exhaust process, the servo motor pulls up the air inlet cover 1312 and hovers it at any angle to control the air volume entering the cooking cavity 110, achieving different exhaust rates and allowing the cooking cavity 110 to maintain different steam concentrations. Figure 10 and Figure 11 As shown, when the exhaust state needs to be closed, the servo motor puts the air inlet cover 1312 back.

[0112] In one possible implementation, referring to Figure 6 and Figure 7As shown, the top wall of the air duct shell 122 can be provided with a guide groove 1224, and the driving mechanism 136 can also include a guide rod 1365, which passes through the guide groove 1224 and is inserted into the interior of the exhaust air duct 124 and is connected to the air inlet shell 131; the guide rod 1365 is arranged parallel to the rack 1364.

[0113] In the embodiment of the present application, the guide rod 1365 passes through the guide groove 1224 so that it can move up and down. On the one hand, the guide rod 1365 can provide guidance and support to ensure the precise movement of the gear 1363 and the rack 1364; on the other hand, the guide rod 1365 can help maintain the linear motion trajectory of the gear 1363 and the rack 1364, reduce deviation and shaking, and improve the steering accuracy and stability; on the other hand, by supporting the gear 1363 and the rack 1364, the guide rod 1365 can disperse the force during the movement, reduce the wear and deformation of the gear 1363 and the rack 1364, and extend their service life.

[0114] In the embodiment of the present application, during the transmission between gear 1363 and rack 1364, the rotational motion of gear 1363 is converted into linear motion by the meshing rack 1364. If the guide post is not parallel to the rack 1364, this may cause gear 1363 and rack 1364 to tilt or offset during meshing, thereby causing instability and reduced transmission accuracy. Therefore, the present application arranges guide rod 1365 parallel to rack 1364 to ensure that gear 1363 and rack 1364 are properly aligned during meshing, thereby reducing deviations and errors during the transmission process and improving transmission accuracy and efficiency.

[0115] In one possible implementation, referring to Figure 3 As shown, the air duct housing 122 may include an air duct bottom plate 1222 and an air duct upper cover 1221 ; the air duct upper cover 1221 is connected to the side of the air duct bottom plate 1222 facing away from the cooking cavity 110 , and is surrounded by the air duct bottom plate 1222 to form an exhaust air duct 124 .

[0116] The exhaust fan 121 is connected to the air duct bottom plate 1222, and the exhaust fan 121 is arranged on the side of the air duct upper cover 1221; part of the structure of the air inlet shell 131 is moved in the vertical direction relative to the air duct bottom plate 1222, and the air duct upper cover 1221 is arranged above the air inlet shell 131.

[0117] In the embodiments of the present application, the structure of the air duct cover 1221 is not limited. For example, the cross-section of the air duct cover 1221 can be a trapezoid. With this design, when air flows through the trapezoidal cross-section, the air flow rate is faster and the pressure is lower on the side closer to the wide side of the trapezoid, while the air flow rate is slower and the pressure is higher on the narrow side. This pressure difference causes the air flow to flow from the higher pressure area to the lower pressure area, thereby increasing the air flow speed and improving the heat dissipation effect.

[0118] In the embodiment of the present application, there is no limitation on the structure of the air duct bottom plate 1222. For example, the air duct bottom plate 1222 may be in the form of a flat plate structure, which facilitates the installation of the exhaust fan 121 and helps improve the assembly stability of the exhaust fan 121.

[0119] The embodiment of the present application provides a cooking appliance that can better control the air intake volume of the air inlet interface, helps to ensure that the air inlet interface is exposed during the rapid steam exhaust process so that the air inlet interface has sufficient air intake volume, and hides the air inlet interface when steam exhaust is not performed, so as to reduce the impact on the normal air duct steam exhaust and heat dissipation, thereby being able to adjust the heat dissipation process and the air intake volume required for the steam exhaust process according to actual needs, thereby maximizing the heat dissipation efficiency and steam exhaust efficiency.
