[0041] 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.

[0042] 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. When in use, it is raised to connect the air inlet assembly and the exhaust duct. The air inlet assembly moves relative to the exhaust duct, specifically when it is raised and when it is lowered, using separate power sources. This requires a large number of power sources and is costly.

[0043] In response to the above technical problems, an embodiment of the present application provides a cooking appliance comprising an exhaust duct, an air inlet base, an air inlet cover, and a movable push plate. The air inlet cover is movably arranged at the opening of the exhaust duct, allowing access to the interior of the exhaust duct and sharing the exhaust fan to achieve exhaust and heat dissipation functions. The movable push plate is movably arranged relative to the air inlet base. When the air inlet housing exits the opening of the air duct housing, the movable push plate can be used to block the opening. Therefore, the present application can integrate the functions of raising the air inlet cover and lowering the air inlet cover to block the opening into a single power source, reducing the number of power sources and helping to save costs.

[0044] 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 .

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] In the present application, refer to Figure 2 As shown, the duct housing 130 includes an upper duct cover 132 and an air duct bottom plate 133. The upper duct cover 132 and the air duct bottom plate 133 enclose an exhaust duct 131. The exhaust fan 120 is configured to blow air into the exhaust duct 131. The bottom wall of the duct housing 130 is provided with an opening 134. The air inlet assembly 140 includes an air inlet base 141 and an upper air inlet cover 142. The air inlet base 141 is provided outside the duct housing 130. The upper air inlet cover 142 is arranged to be movable relative to the air inlet base 141 in a first direction, and the upper air inlet cover 142 is opposite to the opening 134. The first direction can be a vertical direction.

[0051] For example, when steam exhaust is required, air inlet cover 142 is lifted relative to air inlet base 141 in a first direction, and air inlet assembly 140 enters exhaust duct 131, thereby connecting the air inlet cavity of air inlet assembly 140 with exhaust duct 131. This maximizes sufficient air intake during rapid steam exhaust and improves exhaust efficiency. For example, the first direction is vertical, with air inlet cover 142 moving upward.

[0052] For example, when exhaust is not required, the air inlet cover 142 falls back relative to the air inlet base 141 in a first direction, withdrawing the air inlet cover 142 from the exhaust duct 131 and disconnecting the air inlet cavity from the exhaust duct 131. This helps ensure that the airflow from the cooling fan is fully utilized for heat dissipation, thereby reducing the impact of air intake at the air inlet housing on normal duct exhaust and heat dissipation. For example, the first direction here is vertical, with the air inlet cover 142 moving downward.

[0053] The first direction can refer to Figure 3 Indicated by the direction of arrow A.

[0054] In this way, by limiting the movable position of the air inlet cover 142 at the opening 134 of the exhaust duct 131, it is possible to enter the exhaust duct 131 or exit from the exhaust duct 131. Sharing one exhaust fan 120 can achieve the functions of exhaust and heat dissipation, which helps to reduce one exhaust fan 120 and reduce costs.

[0055] In the present application, refer to Figure 2 and Figure 3 As shown, the air inlet assembly 140 also includes a movable push plate 143, which is arranged to move horizontally relative to the air inlet base 141. When the movable push plate 143 moves in a direction away from the air inlet base 141, the movable push plate 143 abuts against the air inlet upper cover 142 and pushes the air inlet upper cover 142 to rise into the exhaust duct 131; when the movable push plate 143 moves toward the air inlet base 141, the movable push plate 143 separates from the air inlet upper cover 142, the air inlet upper cover 142 descends and exits from the exhaust duct 131, and at least part of the structure of the movable push plate 143 is blocked in the opening 134.

[0056] The working process of the air inlet assembly 140 provided in this embodiment is as follows:

[0057] When the cooking cavity 110 does not need to exhaust steam, in a normal state, the movable push plate 143 moves toward the air inlet base 141, the movable push plate 143 separates from the air inlet cover 142, the air inlet cover 142 withdraws from the exhaust air duct 131, and at least part of the structure of the movable push plate 143 is blocked by the opening 134; in the process of exhausting steam, the movable push plate 143 moves away from the air inlet base 141, and the movable push plate 143 gradually moves away, exposing the rising channel of the air inlet cover 142. The movable push plate 143 is in contact with the air inlet cover 142, and the movable push plate 143 continuously moves to the right, causing the air inlet cover 142 to rise in the vertical direction; when exhaust is not needed, the movable push plate 143 is disengaged from the air inlet cover 142, and after the air inlet cover 142 returns to the air inlet base 141, at least part of the structure of the movable push plate 143 covers the opening 134 of the air duct shell 130, so that the wind in the air duct is smoother during the exhaust process and the non-exhaust process, thereby reducing the natural loss of internal air.

[0058] For example, when exhaust is required, the moving direction of the push plate 143 can refer to Figure 3 As shown by the arrow B1, for example, it moves to the right. Figure 4 This is a structural diagram of the movable push plate abutting against the air inlet cover and pushing the air inlet cover into the exhaust air duct.

[0059] For example, when exhaust is not required, the moving direction of the push plate 143 can refer to Figure 3 As shown by the arrow B2, for example, it moves to the left. Figure 5 This is a structural diagram of the movable push plate separating from the air inlet cover and the air inlet cover exiting from the exhaust air duct.

[0060] In the cooking appliance 100 provided in this embodiment, the movable push plate 143 is movably arranged relative to the air inlet base 141. When the air inlet housing is withdrawn from the opening 134 of the air duct housing 130, the movable push plate 143 can block the opening 134, and the movable push plate 143 can also push the air inlet cover 142 into the exhaust air duct 131. Therefore, the present application only requires a single power source, and the functions of raising the air inlet cover 142 and lowering the air inlet cover 142 to block the opening 134 can be integrated into a single power source, thereby reducing the number of power sources, thereby saving a power source and helping to save costs.

[0061] In one possible implementation, referring to Figures 3 to 5 As shown, the movable push plate 143 has a lifting surface 1434 and a blocking surface 1435. The lifting surface 1434 and the blocking surface 1435 are located at different positions along the moving direction of the movable push plate 143. When the movable push plate 143 pushes the air inlet cover 142 into the exhaust duct 131, the lifting surface 1434 abuts the air inlet cover 142. When the air inlet cover 142 exits the exhaust duct 131, the blocking surface 1435 blocks the opening 134.

[0062] In the embodiment of the present application, there is no limitation on the structure of the lifting surface 1434. For example, the lifting surface 1434 in this embodiment can be a triangular structure. Due to its unique geometric shape, the triangular structure has high structural stability and load-bearing capacity. On the one hand, when subjected to external forces, the lifting surface 1434 can well maintain its shape and is not easily deformed or collapsed. On the other hand, the design can better disperse and withstand pressure. Compared with other shapes such as rectangles or squares, triangles can provide higher load-bearing capacity using the same material.

[0063] In the embodiment of the present application, the structure of the shielding surface 1435 is not limited. For example, the shielding surface 1435 in this embodiment can be a completely planar structure. In this way, when the air inlet cover 142 exits the exhaust duct 131, the bottom surface of the exhaust duct 131 becomes a flat surface, and the interior of the exhaust duct 131 becomes smoother, thereby helping to reduce losses caused by air turbulence caused by sharp corners in the exhaust duct 131, thereby maximizing the heat dissipation and steam exhaust performance of the cooking appliance 100.

[0064] In a feasible embodiment, the movable push plate 143 moves relative to the air inlet base 141 along a second direction, and the second direction is perpendicular to the first direction.

[0065] In the embodiment of the present application, the first direction may be the moving direction of the air inlet cover 142 relative to the air inlet base 141 in the vertical direction, for example Figure 3 The second direction is the moving direction of the push plate 143, and the second direction may be a horizontal direction, for example Figure 3 By limiting the first direction and the second direction to be perpendicular, the movement of the push plate 143 is facilitated, thereby facilitating the pushing of the air inlet cover 142 from its bottom into the exhaust duct 131 .

[0066] In one possible implementation, referring to Figures 3 to 5 As shown, the movable push plate 143 may include a shielding portion 1431 , a connecting portion 1432 and a lifting portion 1433 , and the shielding portion 1431 , the connecting portion 1432 and the lifting portion 1433 are sequentially connected along the moving direction of the movable push plate 143 .

[0067] The movement process of the movable push plate 143 provided in this embodiment is as follows:

[0068] When the cooking cavity 110 does not need to exhaust steam, in a normal state, the movable push plate 143 moves toward the air inlet base 141, the lifting portion 1433 separates from the air inlet cover 142, the air inlet cover 142 withdraws from the exhaust air duct 131, and the shielding portion 1431 blocks the opening 134; in the process of exhausting steam, the movable push plate 143 moves away from the air inlet base 141, and the movable push plate 143 gradually moves away, exposing the rising channel of the air inlet cover 142, and then the lifting portion 1433 is lifted. The lifting portion 1433 abuts against the air inlet cover 142, and the movable push plate 143 continuously moves to the right, causing the air inlet cover 142 to rise in the vertical direction; when exhaust is not needed, the lifting portion 1433 disengages from the air inlet cover 142, and after the air inlet cover 142 returns to the air inlet base 141, the shielding portion 1431 covers the opening 134 of the air duct shell 130, so that the wind in the air duct is smoother during the exhaust process and the non-exhaust process, thereby reducing the natural loss of internal air.

[0069] In one possible implementation, referring to Figures 3 to 5 As shown, the lifting portion 1433 has a lifting surface 1434, which is inclined relative to the moving direction of the movable push plate 143. The air inlet cover 142 has an abutting surface 1421, which is parallel to the lifting surface 1434. When the movable push plate 143 pushes the air inlet cover 142 to move, the lifting surface 1434 abuts against the abutting surface 1421 and slides relative to it.

[0070] It can be understood that the abutment surface 1421 of the air inlet cover 142 is also inclined. In this way, compared with the vertical surface, when the movable push plate 143 of the present application moves in the direction away from the air inlet base 141, the abutment surface 1421 and the lifting surface 1434 cooperate and slide to achieve the lifting of the air inlet cover 142; in addition, when the movable push plate 143 of the present application moves toward the air inlet base 141, the abutment surface 1421 and the lifting surface 1434 are disengaged, and the air inlet cover 142 is caused to fall back under the action of gravity.

[0071] In the embodiment of the present application, there is no limitation on the inclination angle and inclination direction of the lifting surface 1434 and the abutting surface 1421 , and they can be set according to actual needs.

[0072] In this embodiment, the description is mainly based on the example that the lifting surface 1434 and the abutting surface 1421 have the same inclination direction and inclination angle. In this way, on the one hand, when the lifting surface 1434 and the abutting surface 1421 abut each other, the abutting effect between the lifting surface 1434 and the abutting surface 1421 can be guaranteed to the greatest extent; on the other hand, the contact between the lifting surface 1434 and the abutting surface 1421 will be closer, thereby providing better support and stability; on the other hand, due to the consistency of the inclination angle, the movable push plate 143 can move more smoothly, which helps to reduce the friction and resistance caused by the angle difference, thereby improving the working efficiency and performance of the movable push plate 143.

[0073] In a feasible embodiment, the shielding portion 1431 has a shielding surface 1435 , and the shielding surface 1435 is parallel to the plane where the opening 134 is located; the shape of the shielding surface 1435 matches the shape of the opening 134 .

[0074] This design can ensure that the shielding surface 1435 can fit tightly against the opening 134 after being blocked by the opening 134, providing better airflow sealing performance; in addition, the matching shape can also enhance the stability of the shielding plate, making it less likely to deform or shift during use, thereby providing more reliable sealing performance and reducing air leakage.

[0075] In a feasible embodiment, at least part of the structure of the connecting portion 1432 is extended along the moving direction of the movable push plate 143; the first end of the connecting portion 1432 is connected to the lifting portion 1433, and the second end of the connecting portion 1432 is connected to the shielding portion 1431, so that there is a distance between the lifting portion 1433 and the shielding portion 1431.

[0076] In the embodiment of the present application, there is no limitation on the spacing between the lifting portion 1433 and the shielding portion 1431 and the spacing can be set according to actual needs. It is understood that if the spacing between the lifting portion 1433 and the shielding portion 1431 is too small, the shielding portion 1431 may easily collide with the air inlet cover 142 during the movement of the movable push plate 143, affecting stability.

[0077] In one possible implementation, referring to Figures 3 to 5 As shown, the connecting portion 1432 may include a first connecting segment 14321, a second connecting segment 14322 and a third connecting segment 14323, the second connecting segment 14322 is connected between the first connecting segment 14321 and the third connecting segment 14323, and the second connecting segment 14322 extends along the moving direction of the movable push plate 143; the first connecting segment 14321 is connected to the lifting portion 1433; and the third connecting segment 14323 is connected to the shielding portion 1431.

[0078] Such a design can increase the connection area between the connecting portion 1432 and the lifting portion 1433, as well as the connecting portion 1432 and the shielding portion 1431, thereby helping to enhance the connection strength between the connecting portion 1432 and the lifting portion 1433, as well as the connecting portion 1432 and the shielding portion 1431, and ensure the connection stability between the connecting portion 1432 and the lifting portion 1433, as well as the connecting portion 1432 and the shielding portion 1431.

[0079] In the embodiment of the present application, the first connecting section 14321 can be bent relative to the lifting portion 1433 in a direction away from the air inlet housing, and the third connecting section 14323 can be bent relative to the shielding portion 1431 in a direction away from the air inlet housing. This can further increase the connection area between the connecting portion 1432 and the lifting portion 1433, and between the connecting portion 1432 and the shielding portion 1431, thereby ensuring connection stability.

[0080] In one feasible embodiment, the lifting portion 1433 and the connecting portion 1432 are located on the side of the air inlet base 141, and the air inlet cover 142 is disposed on the outside of the air inlet base 141. In this way, the movable push plate 143 can avoid interference with the air inlet base 141 during movement, thereby ensuring smooth lifting and lowering of the air inlet cover 142.

[0081] In the embodiment of the present application, the lifting portion 1433 can abut and cooperate with the lower end of the side wall of the air inlet cover 142, so that the lifting portion 1433 can abut and push the air inlet cover 142 from the bottom of the air inlet cover 142, thereby achieving the smooth lifting and falling of the air inlet cover 142 to the greatest extent.

[0082] In a feasible embodiment, there may be two lifting portions 1433 and two connecting portions 1432 , and the two lifting portions 1433 and the two connecting portions 1432 are connected in a one-to-one correspondence and are arranged in parallel on opposite sides of the air inlet base 141 .

[0083] With this design, on the one hand, the design on both sides makes the lifting portion 1433 and the connecting portion 1432 form a more stable whole, which helps to reduce the deformation and displacement of the lifting portion 1433 and the connecting portion 1432 when subjected to force, improves the overall stability of the structure, and thus maximizes the stability of the movement process; on the other hand, the design on both sides can effectively disperse forces, such as gravity or wind force, reduce the concentrated stress on a single connection point, and thus reduce the possibility of deformation and damage; on the other hand, it helps to improve the rigidity of the structure.

[0084] In one possible implementation, referring to Figures 3 to 5 As shown, the cooking appliance 100 may further include a driving mechanism 150, which is arranged on a side of the movable push plate 143 away from the air inlet assembly 140. The driving mechanism 150 may include a driving unit 151 and a telescopic rod 152. The driving unit 151 is arranged below the air duct housing 130. The driving unit 151 is configured to drive the telescopic rod 152 to telescopically move, and the end of the telescopic rod 152 is connected to the movable push plate 143.

[0085] For example, the driving unit 151 in this embodiment can be a motor, a device for providing power and control, and the telescopic rod 152 is a device for achieving linear motion. The telescopic rod 152 achieves linear propulsion through the kinetic force generated by the driving unit 151, which is not limited in this embodiment.

[0086] In one possible implementation, referring to Figure 1 As shown, the air inlet assembly 140 also includes an air inlet pipe 144 and an air inlet valve 145. The air inlet base 141 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.

[0087] 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. 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. Air, under the action of the exhaust fan 120, enters the air inlet port and then passes through the air inlet valve 145 into the cooking cavity 110, squeezing out the steam in the cooking cavity 110 and achieving rapid steam exhaust.

[0088] In one possible implementation, referring to Figure 1 As shown, the cooking appliance 100 further includes an exhaust pipe 160 , one end of which is in communication with 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 .

[0089] 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.

[0090] 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.

[0091] In the present application, refer to Figure 1 and Figure 2As 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.

[0092] An embodiment of the present application provides a cooking appliance, including an exhaust duct, an air inlet base, an air inlet cover and a movable push plate. The air inlet cover is movably arranged at the opening position of the exhaust duct, and can enter the interior of the exhaust duct, sharing the exhaust fan to realize the exhaust and heat dissipation functions; the movable push plate is movably arranged relative to the air inlet base, and when the air inlet shell exits from the opening of the air duct shell, the opening can be blocked by the movable push plate. Therefore, the present application can integrate the functions of lifting the air inlet cover and falling back the air inlet cover to cover the opening into one power source, thereby reducing the number of power sources and helping to save costs.
