[0041] The cooking appliance is provided with an air inlet, 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; the other part of the airflow from the heat dissipation fan is used to discharge the high-temperature steam after cooking. Specifically, it mainly enters the cooking cavity through the air inlet and squeezes out the high-temperature steam in the cooking cavity.

[0042] Since the size of the air inlet is stable, the air volume entering the cooking cavity cannot be adjusted well. During the cooking process, the food cannot be properly passed through different air inlets to maintain different steam concentrations in the cooking cavity, resulting in poor cooking effect of the food.

[0043] To address the above technical issues, embodiments of the present application provide a cooking appliance comprising an air inlet housing, the air inlet housing being provided with an air outlet, and the air outlet being provided with a movable cover. The movable cover is rotatable relative to the air inlet housing to close or open the air outlet and adjust the ventilation area of the air outlet. By adjusting the air volume flowing out of the air outlet, the present application facilitates adjusting the air volume entering the cooking cavity, achieving rapid steam exhaust, ensuring that different steam concentrations are maintained in the cavity through different air inlet volumes during the cooking process, thereby improving the cooking effect and user experience.

[0044] 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.

[0045] 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 .

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In the present application, refer to Figures 1 to 3 As shown, the cooking appliance 100 includes an exhaust fan 120, an air duct housing 130 and an air inlet housing 140, and the exhaust fan 120, the air duct housing 130 and the air inlet housing 140 are all arranged on the box body.

[0050] For example, the exhaust fan 120, air duct housing 130, and air inlet housing 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 and air inlet components outside the enclosure, the heat exchange process can be better controlled, reducing energy consumption and lowering operating costs.

[0051] In the present application, refer to Figure 3 As shown, the air duct housing 130 has an exhaust air duct 131 , and the cooking cavity 110 is connected to the exhaust air duct 131 ; the exhaust fan 120 is located on the air inlet side of the exhaust air duct 131 and is configured to blow air into the upstream of the exhaust air duct 131 .

[0052] At least part of the structure of the air inlet shell 140 is located in the exhaust air duct 131 and is surrounded to form an air inlet cavity 141, which is connected to the cooking cavity 110; an air inlet port 142 is provided on the side of the air inlet cavity 141 facing the exhaust fan 120.

[0053] The cooking appliance 100 may further include an exhaust pipe 180 , 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 .

[0054] The exhaust fan 120 dissipates heat as follows: During cooking, steam generated in the steam generating line enters the cooking cavity 110 to heat the food. Excess steam flows through the exhaust pipe 180 and enters the exhaust duct 131. The exhaust fan 120 then blows air into the exhaust duct 131, discharging the steam outside 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 components and the cooking appliance 100, and preventing damage to the components.

[0055] For example, the heat dissipation path of the exhaust fan 120 can refer to Figure 3 As shown in the direction of arrow a.

[0056] The exhaust path of the exhaust fan 120 is as follows: 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 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 180, and then enters the downstream of the exhaust duct 131 through the exhaust pipe 180. The exhaust fan 120 discharges the high-temperature steam in the exhaust duct 131 to the outside of the cooking appliance 100.

[0057] For example, the exhaust path of the exhaust fan 120 can refer to Figure 3 As shown in the direction of arrow b.

[0058] 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.

[0059] In the present application, refer to Figure 1 and Figure 2 As shown, cooking appliance 100 includes a panel 190 connected to the housing. Panel 190 is provided with a steam exhaust port 191, 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 191, 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 191 on panel 190 facilitates regular cleaning and maintenance, reduces grease accumulation, and maintains a clean and hygienic cooking appliance 100.

[0060] During the cooking process, such as the baking process of bread, the cooking cavity 110 generally needs to maintain a suitable air intake to maintain different steam concentrations and improve the cooking effect of the food. Figure 3 As shown, an air outlet 143 may be provided on the side of the air inlet chamber 141 facing away from the exhaust blower 120. Both the air inlet 142 and the air outlet 143 are connected to the exhaust duct 131. Along the direction of airflow in the exhaust duct 131, the interface between the exhaust pipe 180 and the exhaust duct 131 is located downstream of the air outlet 143.

[0061] Reference Figure 3 As shown, the air outlet 143 may be provided with a movable cover 150 , which is rotatable relative to the air inlet housing 140 to close the air outlet 143 , or to open the air outlet 143 and adjust the ventilation area of the air outlet 143 .

[0062] In the embodiment of the present application, there is no limitation on the rotation mode of the movable cover 150 and the air inlet housing 140 , and they can be specifically set according to the actual product.

[0063] For example, if it is necessary to increase the air volume in the cooking cavity 110, the angle of the movable cover 150 is adjusted, and the movable cover 150 is rotated relative to the air inlet shell 140 to close the air outlet 143, thereby reducing the ventilation area of the air outlet 143, reducing the airflow entering from the air outlet 143 to the exhaust duct 131, and thereby increasing the airflow entering from the air inlet cavity 141 into the cooking cavity 110.

[0064] in, Figure 5 This is a structural diagram showing that the movable cover is rotatable relative to the air inlet housing to close the air outlet.

[0065] For example, if it is necessary to reduce the air volume in the cooking cavity 110, the angle of the movable cover 150 is adjusted, and the movable cover 150 is rotated relative to the air inlet shell 140 to open the air outlet 143, thereby increasing the ventilation area of the air outlet 143, increasing the airflow from the air outlet 143 into the exhaust duct 131, and thereby reducing the airflow from the air inlet cavity 141 into the cooking cavity 110.

[0066] in, Figure 7 This is a structural diagram showing that the movable cover is rotated relative to the air inlet housing to open the air outlet.

[0067] Therefore, the cooking utensil 100 provided in the present application helps to adjust the air volume entering the cooking cavity 110 by adjusting the amount of air flowing out from the air outlet 143, thereby achieving rapid steam exhaust, ensuring that during the cooking process, different air intake volumes are used to maintain different steam concentrations in the cavity, thereby improving the cooking effect of the food and enhancing the user experience.

[0068] It should be noted that the actual amount of air entering the cooking cavity 110 is adjusted by controlling the angle of the movable cover 150. The actual amount of air entering the cooking cavity 110 here refers to: the amount of air entering the air inlet 142 minus the amount of air flowing out of the movable cover 150.

[0069] In one possible implementation, referring to Figure 3 As shown, the air inlet cavity 141 extends through the air inlet housing 140 from the air inlet 142 to the air outlet 143 along the air inlet direction of the exhaust air duct 131. This helps ensure smooth airflow, thereby more smoothly adjusting the amount of air flowing out of the air outlet 143, and thereby controlling the amount of exhaust airflow entering the cooking cavity 110 from the air inlet housing 140.

[0070] In one possible implementation, referring to Figure 3 As shown, the contour shape of the movable cover 150 matches the contour shape of the air outlet 143 ; when projected in the air outlet direction of the air outlet 143 , the movable cover 150 covers the air outlet 143 .

[0071] In the embodiment of the present application, the shape of the air outlet 143 is not limited. For example, the shape of the air outlet 143 can be circular or square, which is not limited in the embodiment. In addition, the size of the air outlet 143 is not limited either.

[0072] By limiting the contour shape of the movable cover 150 to match the contour shape of the air outlet 143, this ensures installation accuracy and stability, reduces errors and adjustments during installation, and thus improves overall installation efficiency and quality. Furthermore, the matching contour design ensures a better seal between the movable cover 150 and the air outlet 143, preventing air leakage. Furthermore, the matching contour design optimizes air flow and reduces resistance. Furthermore, the matching contour design makes the movable cover 150 and the air outlet 143 more coordinated and aesthetically pleasing in appearance, enhancing the overall design unity and visual effect.

[0073] In one possible implementation, referring to Figure 3 As shown, the air inlet cavity 141 may include a ventilation area 1411 and an air supply area 1412 that are connected to each other. The ventilation area 1411 is located inside the air duct housing 130, and the air supply area 1412 is connected to the cooking cavity 110.

[0074] In the embodiment of the present application, the ventilation area 1411 and the air supply area 1412 can be arranged in layers along the vertical direction. Figure 3As shown, the ventilation area 1411 and the air supply area 1412 are located on the upper and lower sides along the vertical direction. This can better utilize the effect of gravity, allowing air to flow naturally to the air supply area 1412, reducing air flow consumption. In addition, this design ensures that the air flows in layers in the vertical direction, avoiding ineffective air circulation and improving the exhaust effect.

[0075] In the present application, refer to Figure 3 As shown, the air inlet 142 and the air outlet 143 are located at the two horizontal ends of the ventilation area 1411. For example, the air inlet 142 and the air outlet 143 are arranged opposite each other, which can effectively shorten the air flow path and improve air circulation efficiency. In addition, it helps to reduce the residence time of air in the ventilation area 1411 and prevent the accumulation of air pollutants.

[0076] In one possible implementation, referring to Figure 1 and Figure 2 As shown, the cooking appliance 100 may further include an air inlet duct 160 and an air inlet valve 161. The side wall of the air supply area 1412 may be provided with a ventilation joint 144. The first end of the air inlet duct 160 is connected to the ventilation joint 144, and the second end of the air inlet duct 160 is connected to the cooking cavity 110. The air inlet valve 161 is connected to the air inlet duct 160, and the air inlet valve 161 is configured to control the on and off of the air inlet duct 160.

[0077] In the embodiment of the present application, the air inlet valve 161 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 131 is diverted to the air inlet 142. However, due to the action of the air inlet valve 161, 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 161 is opened. Under the action of the exhaust fan 120, air enters the air inlet 142, passes through the air inlet valve 161, and enters the cooking cavity 110, squeezing out the steam in the cooking cavity 110 and achieving rapid steam exhaust.

[0078] In addition, this arrangement ensures that even if the sealing ring of the air inlet valve 161 ages and produces a slight amount of air leakage after long-term use, steam leaking into the exhaust duct 131 will be pushed back by the wind force of the exhaust fan 120, thereby ensuring that there will be no impact on electrical components.

[0079] In the embodiment of the present application, there is no limitation on the structure of the ventilation joint 144. For example, the shape of the ventilation joint 144 can be adapted to the shape of the air inlet pipe 160. For example, a portion of the outer wall of the ventilation joint 144 is embedded in the inner wall of the air inlet pipe 160. This helps to improve the connection stability between the ventilation joint 144 and the air inlet pipe 160, and improves the sealing performance, thereby reducing air leakage.

[0080] In a feasible embodiment, the ventilation joint 144 and the air inlet 142 are located at the same end of the air inlet shell 140; when the air inlet valve 161 is opened, at least part of the air flow entering the air inlet 142 is diverted to the air inlet pipe 160 through the air supply area 1412, and enters the cooking cavity 110 from the air inlet pipe 160 to discharge the steam in the cooking cavity 110.

[0081] With this design, the air inlet 142 and the air inlet pipe 160 are located on the upper and lower sides in the vertical direction. In this way, the effect of gravity can be better utilized to allow air to flow naturally to the air inlet pipe 160, reducing wind flow consumption; in addition, this design can ensure that the air flows in layers in the vertical direction, avoid ineffective circulation of air, and improve the exhaust effect.

[0082] In one possible implementation, referring to Figure 3 As shown, the top of the movable cover 150 can be rotatably connected to the upper edge of the air outlet 143 via a rotating shaft 145. The movable cover 150 is rotated to adjust the opening and closing angle relative to the air outlet 143 to adjust the air volume of the air outlet 143.

[0083] This design makes the air outlet 143 more flexible and the air volume of the air outlet 143 can be adjusted according to actual needs. In addition, the structure of the present application is simple and easy to implement, does not require a complex mechanical structure, reduces manufacturing costs, and is also easy to maintain and repair.

[0084] In one possible implementation, referring to Figures 4 to 7 As shown, the cooking appliance 100 may further include a driving mechanism 170 , which is disposed on the side of the air inlet housing 140 ; the driving mechanism 170 is connected to the movable cover 150 , and the driving mechanism 170 is configured to drive the movable cover 150 to close or open relative to the air outlet 143 .

[0085] In the embodiments of the present application, the type of drive mechanism 170 is not limited. For example, the drive mechanism 170 may 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 impose any restrictions on this.

[0086] In one possible implementation, referring to Figure 5 and Figure 7 As shown, the driving mechanism 170 may include a driving body 171 and a push rod 172, and the push rod 172 is retractably arranged relative to the driving body 171. For example, the driving body 171 may be a motor, a device for providing power and control, and the push rod 172 is a device for achieving linear motion. The push rod 172 achieves linear propulsion through the motion force generated by the driving body 171. This embodiment is not limited to this.

[0087] In the embodiment of the present application, the locations of the drive body 171 and the push rod 172 are not limited. For example, the drive body 171 may be rotatably connected to the air inlet housing, and the push rod 172 may be rotatably connected to the movable cover 150; alternatively, the drive body 171 may be rotatably connected to the movable cover 150, and the push rod 172 may be rotatably connected to the air inlet housing. This embodiment does not limit this.

[0088] In this embodiment, refer to Figure 5 and Figure 7 As shown, the driving body 171 is mainly rotatably connected to the movable cover 150, and the push rod 172 is rotatably connected to the air inlet housing. In this way, the angle of the movable cover 150 is controlled by the push rod 172 to adjust the actual air volume entering the cooking cavity 110.

[0089] In one possible embodiment, the movable cover 150 may include multiple grille covers, which are sequentially arranged at the air outlet 143. The multiple grille covers may rotate synchronously relative to the air outlet 143 so that adjacent grille covers abut against each other to seal the air outlet 143; alternatively, gaps may be formed between adjacent grille covers to form air outlets, and the size of the air outlets may be adjusted by rotating the grille covers.

[0090] For example, multiple grilles can form a louver structure. Thus, by adjusting the size of the air outlet, the ventilation level can be controlled. Thus, when the air volume within the cooking cavity 110 needs to be increased, the air outlet is reduced, reducing the airflow entering the exhaust duct 131 from the air outlet 143, thereby increasing the airflow entering the cooking cavity 110 from the air inlet cavity 141. When the air volume within the cooking cavity 110 needs to be reduced, the air outlet is increased, increasing the airflow entering the exhaust duct 131 from the air outlet 143, thereby decreasing the airflow entering the cooking cavity 110 from the air inlet cavity 141.

[0091] In this embodiment, there is no limitation on the number and arrangement of the grid covers, and they can be set according to actual needs.

[0092] In one possible implementation, referring to Figure 3 As shown, the air duct shell 130 may include an air duct upper cover 132 and an air duct bottom plate 133.
