[0046] The cooking appliance is provided with an air inlet assembly, an exhaust duct and a heat dissipation fan. Part of the airflow from the heat dissipation fan is used for heat dissipation during the cooking process, so as to discharge the excess high-temperature steam in the cooking cavity into the exhaust duct during the cooking process; another part of the airflow from the heat dissipation fan is used to discharge the high-temperature steam after cooking is completed. Specifically, it mainly enters the cooking cavity through the air inlet assembly and squeezes out the high-temperature steam in the cooking cavity.

[0047] To ensure effective heat dissipation and steam exhaust from the cooking appliance, the air inlet of the air inlet assembly is located within the exhaust duct. When not in use, the air inlet port is hidden from view and raised to connect the air inlet assembly and the exhaust duct. However, the structure of the air inlet assembly, due to the presence of sharp corners near the air inlet, causes airflow to swirl when it reaches these corners, creating turbulence. This increases internal consumption, resulting in significant airflow losses and poor heat dissipation and steam exhaust from the cooking appliance.

[0048] In response to the above technical problems, an embodiment of the present application provides a cooking appliance, including an air inlet shell, a baffle and a driving mechanism. The air inlet shell is movably set at the opening position of the exhaust air duct and can enter the interior of the exhaust air duct, thereby sharing the exhaust fan to achieve the functions of exhaust and heat dissipation. When the air inlet shell exits from the opening position of the exhaust air duct, the opening can be blocked by the movable baffle. In this way, during normal heat dissipation and exhaust, the interior of the exhaust air duct becomes smoother, which helps to reduce the loss caused by air turbulence caused by sharp corners in the exhaust air duct, thereby reducing air loss during heat dissipation and exhaust, and maximizing the heat dissipation and exhaust effects of the cooking appliance.

[0049] 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.

[0050] 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 .

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In the present application, refer to Figure 1 and Figure 2 As shown, the cooking appliance 100 includes an exhaust fan 120, an air duct housing 130 and an air inlet assembly 140, and the exhaust fan 120, the air duct housing 130 and the air inlet assembly 140 are all arranged on the box body.

[0055] For example, the exhaust fan 120, air duct housing 130, and air inlet assembly 140 can be located outside the enclosure. This, on the one hand, keeps the interior of the enclosure clean, reduces the complexity of the internal structure, and makes cleaning easier. On the other hand, this arrangement facilitates the efficient use of steam and the heat dissipation of the equipment. Furthermore, by locating both the exhaust assembly and air inlet assembly 140 outside the enclosure, the heat exchange process can be better controlled, reducing energy consumption and lowering operating costs.

[0056] In the present application, refer to Figure 2 As shown, the air duct housing 130 includes an air duct upper cover 132 and an air duct bottom plate 133, and the air duct upper cover 132 and the air duct bottom plate 133 are arranged to form an exhaust air duct 131. The exhaust fan 120 is configured to blow air flow into the exhaust air duct 131. The air duct housing 130 has an opening 134, and the air inlet assembly 140 is arranged opposite to the opening 134.

[0057] In this embodiment, the shape of the opening 134 is not limited and can be configured according to the shapes of the air duct housing 130 and the air inlet assembly 140. For example, the shape of the opening 134 can be circular or square, which is not limited in this embodiment. Furthermore, the size of the opening 134 is also not limited.

[0058] In the embodiment of the present application, the air inlet assembly 140 includes an air inlet shell 141, and at least part of the structure of the air inlet shell 141 is movable relative to the opening 134 so that the air inlet shell 141 can pass through the opening 134 and be inserted into the exhaust duct 131 or exit from the exhaust duct 131.

[0059] For example, when steam exhaust is required, at least a portion of the air inlet housing 141 is raised relative to the opening 134, and the air inlet housing 141 enters the interior of the steam exhaust duct 131 and communicates with the steam exhaust duct 131, thereby maximizing sufficient air intake during rapid steam exhaust and improving steam exhaust efficiency. For example, the raising of the air inlet housing 141 relative to the opening 134 can be performed by moving it vertically upward.

[0060] For example, when exhaust is not needed, at least part of the structure of the air inlet housing 141 moves downward relative to the opening 134, and the air inlet housing 141 withdraws from the exhaust air duct 131, disconnecting the air inlet housing 141 from the exhaust air duct 131, which helps to ensure that the airflow of the cooling fan can be fully used for heat dissipation, thereby reducing the impact of air intake at the air inlet housing 141 on normal air duct exhaust heat dissipation.

[0061] In the present application, refer to Figures 3 to 5As shown, the air inlet assembly 140 includes a shielding plate 142 and a driving mechanism 143. The output end of the driving mechanism 143 is connected to the shielding plate 142. The driving mechanism 143 is configured to drive the shielding plate 142 to move relative to the air inlet housing 141, so that when the air inlet housing 141 exits the exhaust air duct 131, the shielding plate 142 is blocked by the opening 134. The air inlet housing 141 and the shielding plate 142 move in different directions to ensure smooth movement when the two abut and cooperate.

[0062] The working process of the air inlet assembly 140 provided in this embodiment is as follows:

[0063] When the cooking cavity 110 needs to exhaust steam, the driving mechanism 143 drives the baffle 142 to move relative to the air inlet shell 141. When the baffle 142 moves to the final position, at least part of the structure of the air inlet shell 141 is lifted relative to the opening 134, and the air inlet shell 141 enters the exhaust air duct 131 and communicates with the exhaust air duct 131. Air is blown into the cooking cavity 110 to ensure that there is sufficient air intake in the cooking cavity 110 during rapid exhaust, thereby improving the exhaust efficiency. When the cooking cavity 110 does not need to exhaust steam, at least part of the structure of the air inlet shell 141 moves downward relative to the opening 134, and the air inlet shell 141 withdraws from the exhaust air duct 131. The driving mechanism 143 drives at least part of the structure of the air inlet shell 141 to retreat relative to the air inlet shell 141, and the baffle 142 blocks the opening 134.

[0064] For example, when exhaust is required, the moving direction of the shielding plate 142 can refer to Figure 3 As shown by the arrow direction A1, for example, moving to the right; when exhaust is not required, the moving direction of the shielding plate 142 can refer to Figure 3 As shown in the direction of the middle arrow A2, for example, moving to the left.

[0065] in, Figure 4 A schematic diagram of the structure of the driving mechanism provided in this embodiment driving the shielding plate to move and the air inlet cover to lift; Figure 5 This is a structural diagram of the driving mechanism provided in this embodiment driving the baffle to move and the air inlet cover to retract.

[0066] In this way, when the air inlet shell 141 exits from the opening 134 of the exhaust duct 131, the opening 134 is blocked by the movable baffle 142. During normal heat dissipation and exhaust, the bottom surface of the exhaust duct 131 forms a flat surface, making the interior of the exhaust duct 131 smoother, which helps to reduce the loss caused by air turbulence caused by the sharp corners in the exhaust duct 131, and further reduces the air loss during the heat dissipation and exhaust process, thereby maximizing the heat dissipation and exhaust effects of the cooking appliance 100.

[0067] In one possible implementation, referring to Figure 2As shown, the opening 134 is located on the bottom wall of the air duct housing 130, and the air inlet housing 141 is disposed below the air duct housing 130 and opposite to the opening 134. For example, the air inlet housing 141 and the opening 134 can be disposed opposite each other, so that the air inlet housing 141 can be easily moved relative to the air inlet housing 141.

[0068] In order to reduce turbulence formation and reduce wind loss, in the embodiment of the present application, reference is made to Figure 4 As shown, an air guide surface 1415 may be provided on the upper portion of the air inlet housing 141 ; when the air inlet housing 141 exits from the exhaust air duct 131 , the shielding plate 142 is located above the air guide surface 1415 .

[0069] In this way, at least part of the structure of the air inlet shell 141 is lifted relative to the opening 134, and the air inlet shell 141 enters the exhaust duct 131 and is connected with the exhaust duct 131. The air guide surface 1415 is used to guide the airflow. Compared with the structure with sharp corners at some positions of the air inlet component 140 near the air inlet, in the embodiment of the present application, the airflow is guided by the air guide surface 1415, which helps to reduce the problem of swirling, thereby reducing the loss caused by air turbulence caused by the sharp corners in the exhaust duct 131, reducing the air loss during the heat dissipation and exhaust process, and maximizing the heat dissipation and exhaust effects of the cooking appliance 100.

[0070] In order to further reduce wind loss, in the embodiment of the present application, referring to Figure 4 As shown, an air inlet port 1416 is provided on the side of the air inlet housing 141 facing the exhaust fan 120. Relative to the horizontal direction, an air guide surface 1415 is tilted downward from the air inlet port 1416. For example, the air guide surface 1415 in this embodiment can be streamlined.

[0071] In this way, the design of the streamlined air guide surface 1415 can, on the one hand, guide the airflow entering the air inlet shell 141 to flow downward and turn, and on the other hand, guide the airflow in the exhaust duct 131 to reduce airflow loss; on the other hand, the streamlined design optimizes the shape of the air inlet shell 141 to make its surface smoother, which helps to reduce the resistance of air flow and improve the flow efficiency of the airflow.

[0072] In order to further reduce wind loss, in the embodiment of the present application, referring to Figure 4 As shown, at least a portion of the end of the air guide surface 1415 away from the exhaust fan 120 may have an arc-shaped air guide section 1417. The curvature and extension length of the arc-shaped air guide section 1417 are not limited and may be set based on actual conditions. This embodiment does not impose any limitations on this.

[0073] With this design, on the one hand, the arc-shaped air guide section 1417 can guide the airflow entering from the air inlet interface 1416 to change the direction and speed of the airflow, thereby more effectively guiding the airflow to flow in a predetermined direction; on the other hand, the arc-shaped design can more effectively optimize the shape of the air inlet shell 141, making its surface smoother, which helps to reduce the resistance of air flow and improve the flow efficiency of the airflow.

[0074] In the embodiment of the present application, the curved air guide section 1417 is inclined from top to bottom along the airflow direction within the exhaust duct 131, from the side adjacent to the air inlet port 1416 to the side away from the air inlet port 1416. This ensures that when the air inlet housing 141 exits the exhaust duct 131, the position of the curved air guide section 1417 is lower than the position of the opening 134. If the position of the curved air guide section 1417 is higher than the position of the opening 134 when the air inlet housing 141 exits, the shielding plate 142 cannot effectively block the opening 134, and thus the bottom surface of the exhaust duct 131 cannot effectively form a flat surface. Therefore, during normal heat dissipation and exhaust, this embodiment ensures that the bottom surface of the exhaust duct 131 forms a flat surface, making the interior of the exhaust duct 131 smoother.

[0075] In a feasible embodiment, when the driving mechanism 143 drives the baffle plate 142 to move and cover the opening 134, the baffle plate 142 abuts against the wind guide surface 1415. In this way, it can effectively ensure that the baffle plate 142 contacts the air inlet shell 141 during the movement, so that the baffle plate 142 pushes the air inlet shell 141 to make the air inlet shell 141 exit from the exhaust air duct 131.

[0076] In a feasible embodiment, the shielding plate 142 is located on a side of the air duct housing 130 away from the exhaust fan 120 ; the shielding plate 142 is movable along a first direction, wherein the first direction is parallel to the plane where the opening 134 is located.

[0077] It should be noted that the first direction is limited to be parallel to the plane where the opening 134 is located. In this way, when the air inlet shell 141 exits from the opening 134 of the exhaust air duct 131, it can ensure that the opening 134 is filled as much as possible, so that the opening 134 is filled by the baffle plate 142, which helps to reduce the gap between the baffle plate 142 and the opening 134, and helps to ensure that when exhaust is not required, the airflow of the cooling fan can be fully used for heat dissipation, thereby reducing the impact of the air intake at the air inlet shell 141 on the normal air duct exhaust heat dissipation.

[0078] In one possible implementation, referring to Figure 4As shown, the baffle 142 may include a baffle body 1421 and a connecting portion 1422, the baffle body 1421 is connected to the connecting portion 1422, and the baffle body 1421 is configured to block the opening 134; the driving mechanism 143 includes a driving unit 1431 and a telescopic rod 1432, the driving unit 1431 is arranged below the air duct shell 130, the driving unit 1431 is configured to drive the telescopic rod 1432 to telescopically move, and the end of the telescopic rod 1432 away from the driving unit 1431 is connected to the connecting portion 1422.

[0079] In the present embodiment, the type of drive unit 1431 is not limited. For example, the drive mechanism 143 can include an electrical drive, a hydraulic drive, or a mechanical drive. Mechanical drives, such as cam-link mechanisms, have advantages such as simple structure, low cost, and reliable operation. This embodiment does not limit this.

[0080] For example, the driving unit 1431 in this embodiment can be a motor, a device for providing power and control, and the telescopic rod 1432 is a device for achieving linear motion. The telescopic rod 1432 achieves linear propulsion through the kinetic force generated by the driving unit 1431, and this embodiment does not limit this.

[0081] It can be understood that the baffle body 1421 in this embodiment can be a flat structure, and the surface of the baffle body 1421 that blocks the opening 134 is a flat surface. This helps to form a flat surface on the bottom surface of the exhaust duct 131 when the air inlet shell 141 is retracted, thereby reducing the loss caused by air turbulence caused by the sharp edges in the exhaust duct 131.

[0082] In one feasible embodiment, the shape of the baffle body 1421 can match the shape of the opening 134. This design ensures that the baffle body 1421 can fit tightly against the opening 134 when placed against it, providing a good airflow seal. Furthermore, the matching shape enhances the stability of the shielding plate 142, making it less likely to deform or shift during use, thereby providing a more reliable seal and reducing air leakage.

[0083] When the baffle body 1421 is positioned to block the opening 134, the connecting portion 1422 abuts against the side of the air outlet 1418 of the air inlet housing 141. For example, the connecting portion 1422 abuts against the outside of the air outlet 1418, thereby further preventing air from flowing out of the gap between the air inlet housing 141 and the opening 134 and improving the sealing performance.

[0084] In one possible implementation, referring to Figure 3As shown, a fixing groove 1423 may be provided on the side of the connecting portion 1422 facing the telescopic rod, and a clamping portion 1433 may be provided at the end of the telescopic rod 1432. The shape, size, and location of the clamping portion 1433 and the fixing groove 1423 are not limited and may be specifically configured according to the actual product.

[0085] In this way, during assembly, the clamping portion 1433 is clamped in the fixing groove 1423, which helps to improve the connection stability between the baffle plate 142 and the driving mechanism 143, and thereby ensures to the greatest extent the stability of the driving mechanism 143 driving the baffle plate 142 to move relative to the air inlet shell 141; moreover, on the basis of fixing the telescopic rod 1432, the telescopic rod 1432 can be constrained in the derivation direction.

[0086] In one possible implementation, referring to Figures 3 to 5 As shown, the air inlet shell 141 may include an air inlet base 1411 and an air inlet cover 1412, and the air inlet cover 1412 and the air inlet base 1411 are arranged to form an air inlet cavity 1413; the air inlet cover 1412 is arranged to move in the vertical direction relative to the opening 134; when the air inlet cover 1412 protrudes from the opening 134 to the inside of the exhaust duct 131, the air inlet cavity 1413 is connected to the exhaust duct 131.

[0087] In the embodiment of the present application, there is no limitation on the arrangement of the air inlet base 1411 and the air inlet cover 1412. For example, the air inlet cover 1412 can cover the air inlet base 1411, but this embodiment does not limit this. Furthermore, the air inlet cover 1412 is arranged to be movable in the vertical direction relative to the opening 134.

[0088] Specifically, when steam exhaust is required, the air inlet cover plate 1412 moves upward relative to the opening 134 , and when steam exhaust is not required, the air inlet cover plate 1412 moves downward relative to the opening 134 in the vertical direction.

[0089] In one possible implementation, referring to Figure 3 As shown, a rebound mechanism 150 can be provided in the air inlet base 1411, and the top end of the rebound mechanism 150 abuts against the air inlet cover 1412. The rebound mechanism 150 is configured to apply a thrust toward the inside of the opening 134 to the air inlet cover 1412, so that when the baffle 142 opens the opening 134, the air inlet cover 1412 moves at least into the exhaust duct 131.

[0090] It will be appreciated that the rebound mechanism 150 and the aforementioned drive mechanism 143 in this embodiment constitute two power mechanisms. The rebound mechanism 150 is used to apply a thrust toward the inward direction of the opening 134 to the air inlet cover 1412 when the shielding plate 142 opens the opening 134, thereby moving the air inlet cover 1412 at least into the exhaust duct 131. Specifically, the rebound mechanism 150 applies a thrust to the air inlet cover 1412 in a vertical direction. The drive mechanism 143 drives the shielding plate 142 to move relative to the air inlet housing 141 along a plane parallel to the opening 134.

[0091] In this way, when exhaust is required, the driving mechanism 143 drives the baffle 142 to move relative to the air inlet shell 141. When the baffle 142 moves to the final position, the air inlet cover 1412 is supported by the elastic force of the rebound mechanism 150, and the air inlet cover 1412 rises in the vertical direction and enters the exhaust duct 131 to connect the air inlet interface 1416 with the exhaust duct 131; when exhaust is not required, the driving mechanism 143 drives the air inlet cover 1412 to move, so that the air inlet cover 1412 applies a downward thrust to the rebound mechanism 150, the rebound mechanism 150 retracts, and the driving mechanism 143 drives the baffle 142 to block the opening 134.

[0092] In one possible implementation, referring to Figure 3 As shown, the rebound mechanism 150 may include a rebound base 151, an elastic member and a support rod 152. The rebound base 151 is connected to the air inlet base 1411. The elastic member is arranged on the rebound base 151. The first end of the support rod 152 abuts against the elastic member, and the second end of the elastic member abuts against the bottom of the top wall of the air inlet cover 1412.

[0093] In the embodiment of the present application, the connection method between the rebound base 151 and the air inlet base 1411 is not limited and can be set according to actual conditions. In addition, the type of elastic member is not limited. For example, the elastic member can be a spring. This embodiment does not limit this.

[0094] Specifically, the movement process of the rebound mechanism 150 of this embodiment is: when exhaust is required, under the elastic force of the elastic member, the air inlet cover 1412 is supported by the support rod 152, and the air inlet cover 1412 rises in the vertical direction and enters the exhaust duct 131 to connect the air inlet interface 1416 with the exhaust duct 131; when exhaust is not required, the air inlet cover 1412 applies a downward thrust to the support rod 152, the elastic member retracts, and the driving mechanism 143 drives the shielding plate 142 to block the opening 134.

[0095] It should be noted that the structure of the rebound mechanism 150 includes but is not limited to the structure in this embodiment. It can also adopt a structure in which a tension spring is combined with a lever, or an active drive recovery method such as a lifting motor, and can be specifically set according to actual needs.

[0096] In a feasible embodiment, the air inlet base 1411 is located below the air duct shell 130, and the top circumferential edge of the air inlet base 1411 is connected to the outer edge of the opening 134; the air inlet cover 1412 is embedded in the air inlet base 1411 from above the air inlet base 1411.

[0097] In this way, when the air inlet shell 141 exits from the opening 134 of the exhaust duct 131, the opening 134 can be filled as much as possible, thereby filling the opening 134 through the baffle plate 142, which helps to reduce the gap between the baffle plate 142 and the opening 134, and helps to ensure that when exhaust is not required, the airflow of the cooling fan can be fully used for heat dissipation, thereby reducing the impact of the air intake at the air inlet shell 141 on the normal air duct exhaust heat dissipation.

[0098] In one possible implementation, referring to Figure 5 As shown, guide grooves 1414 can be provided on both sides of the air inlet base 1411. When the driving mechanism 143 drives the shielding plate 142 to move, the two sides of the shielding plate 142 can be respectively inserted into the corresponding guide grooves 1414. In this way, the shielding plate 142 can move along the air inlet base 1411 to open and close the opening 134, thereby allowing the air inlet cover plate 1412 to pass through the opening 134 and be inserted into the exhaust duct 131 or withdraw from the exhaust duct 131.

[0099] In one possible implementation, referring to Figure 1 As shown, the air inlet assembly 140 can also include an air inlet pipe 144 and an air inlet valve 145. The air inlet base 1411 is provided with a ventilation joint. The first end of the air inlet pipe 144 is connected to the ventilation joint, and the second end of the air inlet pipe 144 is connected to the cooking cavity 110; the air inlet valve 145 is connected to the air inlet pipe 144, and the air inlet valve 145 is configured to control the on and off of the air inlet pipe 144.

[0100] In the embodiment of the present application, the air inlet valve 145 is closed during heat dissipation and opened during steam exhaust. This is because, when the cooking appliance 100 is operating normally, part of the airflow in the exhaust duct 131 is diverted to the air inlet port 1416. However, due to the action of the air inlet valve 145, 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 145 is opened. Under the action of the exhaust fan 120, air enters the air inlet port 1416, passes through the air inlet valve 145, and enters the cooking cavity 110, squeezing out the steam in the cooking cavity 110 and achieving rapid steam exhaust.

[0101] In the embodiments of the present application, the structure of the ventilation connector is not limited. For example, the shape of the ventilation connector can be adapted to the shape of the air inlet pipe 144. For example, a portion of the outer wall of the ventilation connector is embedded in the inner wall of the air inlet pipe 144. This helps to improve the connection stability between the ventilation connector and the air inlet pipe 144, and improves the sealing performance, thereby reducing air leakage.

[0102] In one possible implementation, referring to Figure 1 As shown, the cooking appliance 100 may further include an exhaust pipe 160 , one end of which is connected to the cooking cavity 110 , and the other end of which is connected to an end of the air duct housing 130 away from the exhaust fan 120 .

[0103] The exhaust fan 120 of the present application dissipates heat as follows: During the cooking process, steam generated in the steam generating pipe enters the cooking cavity 110 to heat the food. Excess steam enters the exhaust duct 131 through the exhaust pipe 160. The exhaust fan 120 then blows air into the exhaust duct 131, discharging the steam from the exhaust duct 131 out of the cooking appliance 100. Furthermore, the exhaust fan 120 dissipates heat from the top of the inner pot through the exhaust duct 131. 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.

[0104] The exhaust path of the exhaust fan 120 of the present application is: after the cooking appliance 100 finishes cooking, a part of the air flow blown out by the exhaust fan 120 is diverted to the air inlet pipe 144 of the air inlet assembly 140, and enters the cooking cavity 110 through the air inlet pipe 144, and squeezes the high-temperature steam inside the cooking cavity 110 into the exhaust pipe 160, and then enters the exhaust duct 131 through the exhaust pipe 160. The exhaust fan 120 discharges the high-temperature steam in the exhaust duct 131 to the outside of the cooking appliance 100.

[0105] It can be understood that, in this embodiment, the heat dissipation of the exhaust fan 120 is performed during the cooking process, and the exhaust of the exhaust fan 120 is performed after the cooking is completed.

[0106] In the present application, refer to Figure 1 and Figure 2 As shown, cooking appliance 100 includes a panel 170 connected to the housing. Panel 170 is provided with a steam exhaust port 171, which is communicated with exhaust duct 131. In this embodiment, high-temperature steam within exhaust duct 131 is primarily discharged from cooking appliance 100 through exhaust port 171, helping to ensure that steam and hot air generated during cooking are quickly discharged and prevent excessive temperatures within cooking appliance 100. Furthermore, the location of exhaust port 171 on panel 170 facilitates regular cleaning and maintenance, reduces grease accumulation, and maintains a clean and hygienic cooking appliance 100.

[0107] The embodiment of the present application provides a cooking appliance, which makes the interior of the exhaust duct smoother during normal heat dissipation and exhaust, helps to reduce the loss caused by air turbulence caused by sharp corners in the exhaust duct, and further reduces air loss during the heat dissipation and exhaust process, thereby maximizing the heat dissipation and exhaust effect of the cooking appliance.
