DETAILED DESCRIPTION

[0040] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0041] The cooking device 100 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0042] As shown in FIG. 1 , a cooking device 100 according to an embodiment of the present application includes a housing 90 , an inner pot 10 , a guide channel 4221 , an air duct member 22 , a microwave assembly 42 and a first fan 32 .

[0043] A food access opening 15 is provided on the front side of the housing 90 .

[0044] The inner pot 10 has a cooking space 11 and is arranged in the outer shell 90. The top wall of the inner pot 10 is provided with an air inlet area 12, a return air area 13 and a microwave inlet 14. In the left and right directions, at least a part of the microwave inlet 14 is arranged opposite to the air inlet area 12.

[0045] The cooking space 11 is used for placing food. The cooking device 100 cooks the food, and the food is placed or taken out through the food taking and placing opening 15 on the housing 90 .

[0046] The air outside the inner liner 10 enters the inner liner 10 through the air inlet area 12, and the air inside the inner liner 10 is discharged through the return air area 13. For example, the air inlet area 12 is the area where the multiple hole structures are located, and the return air area 13 is the area where the multiple hole structures are located.

[0047] In which, in the left and right directions, at least a portion of the microwave inlet 14 is arranged opposite the air inlet area 12, that is, in the left and right directions, the microwave inlet 14 can be partially arranged opposite the air inlet area 12, or the entire microwave inlet 14 can be arranged opposite the air inlet area 12.

[0048] The guide channel 4221 is provided between the top wall of the inner pot 10 and the outer shell 90 , and one end of the guide channel 4221 is communicated with the microwave inlet 14 .

[0049] The air duct member 22 is arranged between the top wall of the inner liner 10 and the outer shell 90 . The air duct member 22 and the top wall of the inner liner 10 define an air duct space 21 . The air inlet area 12 and the return air area 13 are located in the air duct space 21 .

[0050] The microwave assembly 42 is disposed between the outer shell 90 and the inner pot 10. The microwave assembly 42 generates microwaves into the guide channel 4221. The guide channel 4221 guides the microwaves generated by the microwave assembly 42 to the microwave inlet 14. The microwaves then enter the cooking space 11 through the microwave inlet 14. The microwaves cause the molecules within the food to resonate, causing friction between the molecules to generate heat.

[0051] The first fan 32 is located in the air duct space 21 .

[0052] Specifically, the first fan 32 arranged in the air duct space 21 disturbs the air in the air duct space 21 to form a flowing airflow, which enters the cooking space 11 from the air duct space 21 through the air inlet area 12, and enters the air duct space 21 from the cooking space 11 through the return air area 13.

[0053] At least a portion of the microwave inlet 14 is positioned directly opposite the air inlet area 12. The positional relationship between the microwave inlet 14 and the air inlet area 12 ensures that the microwave inlet 14, the air inlet area 12, and the food are at equal distances from each other. This allows the flowing air and microwaves to contact the food simultaneously, improving the cooking effect. The fact that the microwave inlet 14 and the air inlet area 12 are at equal distances from the food does not necessarily mean that they are exactly the same; being close to each other can also produce the same effect.

[0054] The temperature of the food rises under the action of microwaves, and the airflow generated by the disturbance of the first fan 32 makes the heat of the food more evenly distributed in the cooking space 11, so that the food is heated more evenly.

[0055] According to the cooking device 100 of the embodiment of the present application, by arranging at least a portion of the microwave inlet 14 to face the air inlet area 12, the distances between the microwave inlet 14, the air inlet area 12 and the food are equal or close, thereby improving the cooking effect.

[0056] Specifically, the cooking device 100 is any one of an air fryer, a microwave oven, and an oven.

[0057] As shown in FIG1 , in some embodiments, the return air region 13 is located behind the microwave inlet 14 in the front-to-back direction, and a portion of the air inlet region 12 is located in front of the microwave inlet 14. By arranging the return air region 13 behind the microwave inlet 14 and a portion of the air inlet region 12 in front of the microwave inlet 14 in the front-to-back direction, the air entering the cooking space 11 through the air inlet region 12 simultaneously contacts the food with the microwaves. Furthermore, the return air region 13 is located behind the microwave inlet 14, thereby reducing the impact of air leaving the cooking space 11 on the food.

[0058] In the front-to-back direction, the return air area 13 is located behind the microwave inlet 14 , that is, in the left-to-right direction, the return air area 13 has no correspondence with the microwave inlet 14 , so as to avoid airflows in different directions interfering with the heating effect of the microwave.

[0059] As shown in FIG1 , in some embodiments, a portion of the air inlet area 12 is located behind the microwave inlet 14. By arranging a portion of the air inlet area 12 behind the microwave inlet 14, that is, in the left-right direction, not only is a portion of the air inlet area 12 aligned with the microwave inlet 14, but another portion of the air inlet area 12 is located behind the microwave inlet 14 and does not correspond to the microwave inlet 14. As a result, the air entering the cooking space 11 from the air inlet area 12 covers the range affected by the microwaves, making the air entering the cooking space 11 more synchronized with the microwaves, thereby improving the cooking effect on the food.

[0060] In some embodiments, there are multiple air inlet areas 12 .

[0061] As shown in Figures 1 and 6, in some embodiments, multiple air inlet areas 12 are spaced apart in the front-to-back direction. By providing multiple air inlet areas 12, and multiple air inlet areas 12 being arranged in the front-to-back direction, the influence range in the front-to-back direction is expanded.

[0062] For example, two air inlet areas 12 are arranged front to back; or, three air inlet areas 12 are arranged front to back; or, four air inlet areas 12 are arranged front to back.

[0063] In other embodiments, multiple air inlet areas 12 are spaced apart in the left-right direction. By providing multiple air inlet areas 12 and multiple air inlet areas 12 being arranged in the left-right direction, the influence range is expanded in the left-right direction.

[0064] For example, two air inlet areas 12 are arranged at intervals along the left-right direction; or, three air inlet areas 12 are arranged at intervals along the left-right direction; or, four air inlet areas 12 are arranged at intervals along the left-right direction.

[0065] In some embodiments, the opening areas of the multiple air inlet regions 12 are different. By setting the opening areas of the multiple air inlet regions 12 to be different, the air intake volume at different locations in the interior space of the inner container 10 is correspondingly different, adaptively meeting the cooking requirements and improving energy utilization.

[0066] For example, the opening area of ​​the air inlet region 12 near the center of the inner space of the liner 10 is larger than the opening area of ​​the air inlet region 12 away from the center, thereby improving energy utilization.

[0067] As shown in FIG6 , in some embodiments, the opening area of ​​the air inlet region 12 closest to the return air region 13 is the largest. By setting the opening area of ​​the air inlet region 12 closest to the return air region 13 to the largest, most of the heat is fully returned to the interior space of the liner 10, further improving energy utilization.

[0068] For example, the air inlet region 12 is the region where the multiple hole structures are located, and the opening area of ​​the air inlet region 12 is the total area of ​​the multiple hole structures. Setting a larger total area can increase the flow rate.

[0069] As shown in Figure 6, in some embodiments, the length of at least one air inlet region 12 extends in the front-to-back direction. By setting the length of at least one air inlet region 12 to extend in the front-to-back direction, the airflow is fully flowed in the front-to-back direction, so that the internal space of the liner 10 is thermally balanced.

[0070] As shown in Figures 8 and 9, in some embodiments, the air duct space 21 has a first portion 211 and a second portion 212, which are intersectingly arranged. A portion of the air intake area 12 and the return air area 13 are located in the first portion 211, and another portion of the air intake area 12 is located in the second portion 212. By arranging a portion of the air intake area 12 and the return air area 13 in the first portion 211 and another portion of the air intake area 12 in the second portion 212, and by intersecting the first portion 211 and the second portion 212, the airflow is not spatially disturbed in just a straight line, thereby expanding the range of influence.

[0071] As shown in FIG8 and FIG9 , specifically, the first portion 211 and the second portion 212 are perpendicular to each other.

[0072] As shown in Figures 8 and 9, in some embodiments, the length of the first portion 211 is greater than the length of the second portion 212. By setting the length of the first portion 211 to be greater than the length of the second portion 212, it is fully adapted to different space requirements and improves utilization.

[0073] As shown in Figures 6, 8, and 9, in some embodiments, the front side of the second portion 212 extends to the front of the top wall of the inner liner 10. By extending the front side of the second portion 212 to the front of the top wall of the inner liner 10, the influence range of the second portion 212 is expanded, avoiding airflow dead corners.

[0074] As shown in Figures 2 and 6, in some embodiments, the first fan 32 is positioned directly opposite the return air region 13 to guide the air in the inner liner 10 from the return air region 13 into the air duct space 21. By having the first fan 32 facing the return air region 13, the air in the inner liner 10 is guided from the return air region 13 into the air duct space 21, thereby expanding the range of influence of the first fan 32 on the inner liner 10 and fully utilizing the effect of the first fan 32.

[0075] Specifically, the first fan 32 is a centrifugal fan, which is arranged relative to the return air area 13. The centrifugal fan draws air from the inner liner 10 to form an airflow, thereby increasing the impact on the inner liner 10. It can be understood that the air inlet end of the centrifugal fan is facing the return air area 13, thereby drawing air from the inner liner 10.

[0076] In other embodiments, the first fan 32 is disposed between the return air area 13 and the air inlet area 12 to guide the air in the inner container 10 from the return air area 13 into the air duct space 21 .

[0077] Specifically, the first fan 32 is an axial flow fan, which is arranged between the return air area 13 and the air inlet area 12 so that the air flow flows unidirectionally in the air duct space 21 and extracts air from the inner tank 10.

[0078] As shown in Figures 11 and 12, in some embodiments, the cooking device 100 further includes a second fan 50 located within the cooking space 11, and the second fan 50 is located below the microwave inlet 14. The second fan 50 is disposed below the microwave inlet 14 and stirs the microwaves, making the microwaves in the cooking space 11 more uniform and improving cooking uniformity.

[0079] Specifically, the second fan 50 is constructed as a metal member.

[0080] As shown in FIG. 12 , the second fan 50 is connected to a stirring motor 51 . The output end of the stirring motor 51 passes through the microwave assembly 42 and is connected to the second fan 50 to drive the second fan 50 to rotate.

[0081] More specifically, the stirring motor 51 and the first fan 32 overlap in the first direction, and by arranging the stirring motor 51 and the first fan 32 to overlap in the first direction, the structure is compacted. For example, the first direction is the up-down direction.

[0082] In some embodiments, the microwave assembly 42 and the first fan 32 are both located on the top wall of the inner container 10 .

[0083] That is to say, the microwave inlet 14 is provided on the top wall of the inner pot 10 , which simplifies the process of the inner pot 10 . For example, there is no need to fix a ceramic plate on the inner pot 10 , thereby optimizing the process types.

[0084] In some embodiments, a splash guard is further provided on the top wall of the inner pot 10 , and the splash guard corresponds to the microwave inlet 14 to prevent oil from splashing into the microwave inlet 14 .

[0085] Specifically, the splash guard and the top wall of the inner pot 10 jointly define a stirring space, and the second fan 50 is arranged in the stirring space. The splash guard prevents oil from splashing into the microwave inlet 14 while preventing oil from splashing on the second fan 50, thereby reducing the workload of subsequent cleaning.

[0086] Specifically, the splash guard is made of quartz, and microwaves can penetrate quartz, utilizing the inherent properties of the quartz material to achieve a splash-proof effect.

[0087] In some embodiments, the microwave assembly 42 includes a microwave generator and a waveguide tube. The microwave generator is located on the rear side of the inner tank 10. The guide channel is integrally formed in the waveguide tube. The waveguide tube cooperates with the microwave generator and the microwave generator extends into the guide channel.

[0088] As shown in Figures 10 to 13, in some embodiments, microwave assembly 42 includes a microwave generator 421 and a waveguide 422. Microwave generator 421 is located at the rear side of inner pot 10, and waveguide 422 cooperates with microwave generator 421 and extends into guide channel 4221. Microwave generator 421 generates microwaves to heat food, and microwave generator 421 is located at the rear side of inner pot 10 to fully utilize the space.

[0089] Specifically, the microwave assembly 42 further includes a tubular metal member 43 , the inner cavity of the tubular metal member 43 is configured as a guide channel 4221 , and the waveguide tube 422 extends into the guide channel 4221 .

[0090] In some embodiments, an air flow channel 99 is provided between the outer wall of the outer shell 90 and the inner tank 10. The air flow channel 99 includes a top air flow channel 92 and a rear air flow channel 95. The waveguide tube 422 is located in the top air flow channel 92, and the magnetron 421 is located in the rear air flow channel 95.

[0091] The present application makes full use of the top side space by arranging the waveguide tube 422 in the top air flow channel 92, so that the overall structure of the cooking device 100 is thinner in the height direction. At the same time, the magnetron 421 is arranged in the rear air flow channel 95 to rationally utilize the space of each part.

[0092] As shown in Figures 8 and 9, in some embodiments, the air duct space 21 includes a plurality of spaced-apart subspaces 213. Each subspace 213 communicates with the cooking space 11 via the air inlet area 12 and the return air area 13. A first fan 32 is provided within each subspace 213, and the microwave inlet 14 is positioned directly opposite the air inlet area 12 corresponding to at least one subspace 213. By arranging the microwave inlet 14 directly opposite the air inlet area 12 corresponding to at least one subspace 213, the air within the at least one subspace 213 can contact the food simultaneously with the microwaves, improving the cooking effect.

[0093] Among them, the microwave inlet 14 is arranged opposite to the air inlet area 12 corresponding to at least one subspace 213, that is, the microwave inlet 14 can be arranged opposite to the air inlet area 12 corresponding to one subspace 213, can be arranged opposite to the air inlet area 12 corresponding to multiple subspaces 213, and can also be arranged opposite to the air inlet area 12 corresponding to all subspaces 213.

[0094] In some embodiments, the microwave inlet 14 is disposed opposite the air inlet area 12 corresponding to each subspace 213. By disposing the microwave inlet 14 opposite the air inlet area 12 corresponding to each subspace 213, the air in each subspace 213 can contact the food synchronously with the microwaves, further improving the cooking effect.

[0095] It should be noted that in the related art, cooking devices use fans to disturb air to form airflow. Usually, multiple fans are set in the same space, and the multiple fans interfere with each other to cause turbulence, which wastes energy.

[0096] The present application sets a plurality of spaced subspaces 213 , and the plurality of spaced subspaces 213 separate the plurality of first fans 32 , thereby improving airflow turbulence, increasing energy utilization, and further improving the heating effect.

[0097] For example, there are two subspaces 213, each of which is provided with a first fan 32, thereby improving airflow turbulence. Alternatively, there are two subspaces 213, with two subspaces 213 separating four first fans 32, and each subspace 213 being provided with two first fans 32, which can also improve airflow turbulence. Alternatively, there are three subspaces 213, with three subspaces 213 separating four first fans 32, with one subspace 213 being provided with two first fans 32, and the other two subspaces 213 being provided with one first fan 32 each, which can also improve airflow turbulence.

[0098] As shown in FIG. 8 , in some embodiments, a partition 23 is provided in the air duct space 21 to separate the air duct space 21 into a plurality of sub-spaces 213 , thereby reducing the number of parts and facilitating assembly.

[0099] In some embodiments, the divider 23 is made of a heat-insulating material. By configuring the divider 23 as a heat-insulating material, the divider 23 separates the plurality of subspaces 213 , while preventing heat transfer between adjacent subspaces 213 , further balancing heating. Furthermore, the duct member 22 is constructed as a heat-insulating member, further concentrating heat.

[0100] As shown in Figures 6 and 8, in some specific embodiments, the partition 23 is fixed to the air duct member 22. By arranging the partition 23 to be fixed to the air duct member 22, the assembly of the cooking device 100 is facilitated.

[0101] In other specific embodiments, the divider 23 is fixed to the inner container 10 to facilitate positioning.

[0102] In other embodiments, there are multiple air duct members 22 , and a subspace 213 is defined between the air duct member 22 and the inner container 10 .

[0103] Specifically, a plurality of duct members 22 are arranged at intervals.

[0104] As shown in FIG. 1 , in some embodiments, a heat shield 221 is provided on the duct member 22 to insulate heat.

[0105] As shown in Figures 2 and 11, in some embodiments, the first fan 32 is connected to the first motor 31, and the first motor 31 is connected to the first fan 32 to drive the first fan 32 to rotate. The first fan 32 is located in the subspace 213, and the first motor 31 is located outside the subspace 213. By arranging the first fan 32 in the subspace 213 and the first motor 31 outside the subspace 213, the airflow is not affected. Compared with the related art in which the drive motor is arranged in the air duct space and affects the flow of air, the airflow in the subspace 213 of the present application is smoother.

[0106] In some embodiments, the air duct space 21 has an air duct inlet and an air duct outlet. The air duct inlet is connected to the return air area 13, and the air duct outlet is connected to the air inlet area 12. As can be understood, the airflow leaves the inner liner 10 through the return air area 13 and enters the air duct space 21 through the air duct inlet; the airflow exits the air duct space 21 through the air duct outlet and enters the inner liner 10 through the air inlet area 12.

[0107] As shown in Figures 1 and 2, in some embodiments, the housing 90 is provided with an air inlet 93 and an air outlet 91. An air flow channel 99 is provided between the housing 90 and the outer wall of the inner container 10, communicating with the air inlet 93 and the air outlet 91, respectively. The cooking space 11 is provided with a first air inlet 111, communicating with the air flow channel 99. The cooking device 100 further includes a third fan 33 located within the air flow channel 99. The provision of the first air inlet 111 communicating with the first air flow channel increases the flow rate of air entering the cooking space 11, and the flow rate of air discharged outside the housing 90 is also increased, thereby improving heat dissipation.

[0108] It should be noted that if the cooking equipment is to cook the ingredients well, the temperature and humidity in the cooking space need to be maintained within a certain range. Excessively high temperature and humidity will also result in poor cooking results. Therefore, in this application, the air discharged outside the outer shell 90 takes away some water vapor and heat, thereby keeping the temperature and humidity in the cooking space 11 within a certain range, thereby improving the cooking effect.

[0109] In the related art, the air in the oven naturally flows to the outside of the oven, and the heat dissipation effect is poor. The present application adds a first air inlet 111, so that more air enters the cooking space 11, and the air flow discharged to the outside of the outer shell 90 is larger, which improves the heat dissipation effect. At the same time, a third fan is set to fully disturb the air, and the air flow discharged to the outside of the outer shell 90 is larger, further improving the heat dissipation effect.

[0110] In some embodiments, the duct member 22 is disposed on the outer wall of the inner liner 10 and is located within the first airflow duct. A duct space 21 is defined between the duct member 22 and the inner liner 10. The inner liner 10 is provided with an air inlet area 12 and an air return area 13, each of which is in communication with the duct space 21. For example, the air inlet area 12 is a region where multiple hole structures are located, and the air return area 13 is a region where multiple hole structures are located.

[0111] The first fan 32 is provided in the air duct space 21. The first fan 32 is provided in the air duct space 21 to disturb the air in the air duct space 21 to form an air flow. The air leaves the air duct space 21 from the air inlet area 12 and enters the inner liner 10. The air leaves the inner liner 10 from the air outlet area and enters the air duct space 21.

[0112] Specifically, the first fan is connected to a first motor 31 . The first motor 31 is disposed outside the air duct space 21 and is connected to the first fan 32 .

[0113] The first motor 31 is connected to the first fan 32 , and the first motor 31 drives the first fan 32 to rotate. At the same time, the first motor 31 is arranged outside the air duct space 21 , and the air flowing in the first air duct dissipates heat for the first motor 31 .

[0114] More specifically, the air duct space 21 is used to guide air from the return air area 13 to the intake air area 12 .

[0115] It can be understood that the first fan 32 in the duct space 21 disturbs the air to form an airflow, and the airflow enters the duct space 21 from the inner tank 10 through the return air area 13. The airflow flows unidirectionally in the duct space 21. The airflow enters the inner tank 10 from the duct space 21 through the air inlet area 12. The airflow flows in the inner tank 10 and then enters the duct space 21 through the return air area 13, forming a unidirectional circulation of the airflow, which makes the heat distribution in the inner tank 10 more balanced and improves the food heating effect.

[0116] As shown in Figures 1 and 2, in some embodiments, an air inlet 93 is provided below the inner container 10, and an air outlet 91 is provided above the inner container 10. The air flow channel 99 includes a bottom air flow channel 94, a rear air flow channel 95, and a top air flow channel 92. The bottom air flow channel 94 is provided at the bottom of the inner container 10 and communicates with the air inlet 93. The upper and lower ends of the rear air flow channel 95 communicate with the bottom air flow channel 94 and the top air flow channel, respectively. The top air flow channel 92 communicates with the air outlet 91. The third fan 33 is provided in the rear air flow channel 95, and the air duct member 22 is provided in the top air flow channel 92. By providing the bottom air flow channel 94, the rear air flow channel 95, and the top air flow channel 92, air enters the cooking device 100 from the air inlet 93, passes through the bottom air flow channel 94, the rear air flow channel 95, and the top air flow channel 92, and is discharged from the cooking device 100 through the air outlet 91, thereby effectively dissipating heat from various parts of the cooking device 100.

[0117] For example, air enters the bottom air flow channel 94 from the air inlet 93, and the air flows in the bottom air flow channel 94 to take away the heat of the bottom structure of the cooking device 100, and then passes through the rear air flow channel 95 and the top air flow channel 92 in turn, taking away the heat of the rear structure and the heat of the top structure of the cooking device 100 in turn, and finally discharges the cooking device 100 from the air outlet 91, thereby discharging the heat of the various structures of the cooking device 100.

[0118] As shown in Figures 1 and 2, in some specific embodiments, the side wall of the inner liner 10 where the air duct member 22 is located is provided with a third air inlet hole 181, which is in communication with the air flow channel 99. By providing the third air inlet hole 181 on the side wall of the inner liner 10 where the air duct member 22 is located, the airflow flowing in the air flow channel 99 can be used to dissipate heat from the air duct member 22.

[0119] As shown in FIG7 , in some specific embodiments, the cooking device 100 further includes a first air guide hood 34 disposed on the outer wall of the inner pot 10. An air guide channel 341 is disposed within the first air guide hood 34. The inlet of the air guide channel 341 communicates with the air flow channel 99. The air guide channel 341 communicates with the first air inlet hole 111 and the third air inlet hole 181, respectively, to direct air to the first air inlet hole 111 and the third air inlet hole 181. By providing the first air guide hood 34 to guide the flow of air, the airflow within the air flow channel 99 is more directional, thereby improving utilization efficiency.

[0120] Among them, an air guide channel 341 is provided in the first air guide cover 34, the entrance of the air guide channel 341 is connected with the air flow channel 99, and the air guide channel 341 is also connected with the first air inlet hole 111 and the third air inlet hole 181 respectively. The airflow in the air flow channel 99 enters the air guide channel 341 through the entrance of the air guide channel 341, and then divides into two branches, and is discharged from the air guide channel 341 from the first air inlet hole 111 and the third air inlet hole 181 respectively. The airflow enters the cooking space 11 from the first air inlet hole 111, and the airflow dissipates heat to the air duct component 22 from the third air inlet hole 181.

[0121] As shown in FIG. 4 and FIG. 5 , in some specific embodiments, the air outlet end of the third fan 33 corresponds to the inlet of the air guide channel 341 .

[0122] In some specific embodiments, the microwave generator 421 mentioned above is located between the first air guide cover 34 and the third fan 33 , and the third fan 33 is used to cool the microwave generator 421 .

[0123] As shown in FIG. 7 , in some embodiments, the first air guide cover 34 includes an air guide bottom plate 342 and an air guide connecting plate 343 .

[0124] The wind guide bottom plate 342 is arranged on the outer wall of the inner liner 10, and the wind guide connecting plate 343 is arranged on the wind guide bottom plate 342. The end of the wind guide connecting plate 343 away from the wind guide bottom plate 342 is connected to the side wall of the inner liner 10 where the air duct member 22 is provided. The wind guide connecting plate 343, the wind guide bottom plate 342, and the inner liner 10 jointly define an air guide channel 341.

[0125] More specifically, the inner liner 10 includes: a rear plate 19 and a top plate 18, the air guide bottom plate 342 is arranged on the rear plate 19, the air guide connecting plate 343 is arranged on the air guide bottom plate 342, and the end of the air guide connecting plate 343 away from the air guide bottom plate 342 is connected to the top plate 18, and the air guide connecting plate 343, the air guide bottom plate 342, the top plate 18 and the rear plate 19 jointly define an air guide channel 341.

[0126] As shown in FIG. 7 , in some embodiments, the first air guide cover 34 is provided with an air outlet 3431 , and the air outlet 3431 connects the air guide channel 341 and the air flow channel 99 .

[0127] As shown in FIG. 7 , specifically, the air outlet 3431 is provided on the air guide connecting plate 343 .

[0128] As shown in Figures 4 and 5, in some embodiments, the cooking device 100 further includes a control module 35 for controlling the operating state of the cooking device 100. The control module 35 is located in the rear airflow passage 95. By locating the control module 35 in the rear airflow passage 95, the air flowing in the rear airflow passage 95 is fully utilized to dissipate heat from the control module 35.

[0129] As shown in Figures 4 and 5 , the cooking device 100 further includes a transformer 351 for converting voltage levels. The transformer 351 is located within the rear airflow passage 95. By locating the transformer 351 within the rear airflow passage 95, the air flowing within the rear airflow passage 95 is fully utilized to dissipate heat from the transformer 351.

[0130] It can be understood that the temperature of the control module 35 rises when it is working, and the higher temperature affects the normal operation of the control module 35. The present application uses the air flowing in the rear air flow channel 95 to dissipate heat from the control module 35, without the need for a separate heat dissipation device, thereby reducing the number of components.

[0131] As shown in FIG. 10 , in some embodiments, the cooking device 100 further includes: a guide rail assembly 70 and a drawer 60 .

[0132] The drawer 60 is used to hold food, and the guide rail assembly 70 is arranged between the inner pot 10 and the outer shell 90. The guide rail assembly 70 is connected to the drawer 60 so that the drawer 60 can be pulled out and arranged in the cooking space 11; the air flow channel 99 also includes side air flow channels 96 located on the left and right sides of the inner pot 10, and the guide rail assembly 70 is located in the side air flow channels 96.

[0133] Among them, the drawer 60 is designed to be pull-out, which makes it easier to place and take out food compared to the solution in the related art where the food carrying space is fixed inside the cooking appliance.

[0134] It should be noted that the drawer 60 and the cooking space 11 can be pulled together so that the cooking device 100 can be embedded in the cabinet of the furniture, which is suitable for different working environments.

[0135] As shown in Figures 11 and 10, in some embodiments, the drawer member 60 includes: a drawer body 63 and a roller 64. The roller 64 is provided at the bottom of the drawer body 63. The roller 64 is suitable for rolling contact with the bottom wall of the inner container 10. The roller 64 assists the drawer member 60 in moving.

[0136] More specifically, the roller 64 is disposed at an end of the drawer 60 away from the opening of the inner container 10 .

[0137] As shown in FIG10 , the drawer body 63 includes a drawer body 631 and a drawer door 632 . The drawer door 632 is connected to the drawer body 631 . The food carrying space is located inside the drawer body 631 . The drawer door 632 is suitable for opening or closing an opening.

[0138] As shown in FIG. 10 , in some specific embodiments, a handle 6321 and a window are provided on the drawer door 632 , a control panel is provided on the housing, and the drawer door 632 is flush with the control panel.

[0139] In some specific embodiments, the drawer 60 is adapted to enter and exit the cooking space 11 by translation and / or rotation.

[0140] That is to say, the drawer 60 can enter and exit the cooking space 11 by translation; or, the drawer 60 can enter and exit the cooking space 11 by rotation; or, the drawer 60 can enter and exit the cooking space 11 both by translation and by rotation.

[0141] The guide rail assembly 70 is provided to guide the movement of the drawer 60 in and out of the cooking space 11 , so that the movement of the drawer 60 is more stable.

[0142] As shown in Figures 5 and 6, in some specific embodiments, the airflow channel 99 further includes side airflow channels 96 located on the left and right sides of the inner liner 10, and the guide rail assembly 70 is located in the side airflow channels 96. By installing the guide rail assembly 70 in the side airflow channels 96, the air flowing in the side airflow channels 96 is used to dissipate heat from the guide rail assembly 70, thereby improving the reliability of the guide rail assembly 70.

[0143] In other specific embodiments, the airflow channel 99 further includes side airflow channels 96 located on the left and right sides of the inner liner 10. There are multiple guide rail assemblies 70, and the multiple guide rail assemblies 70 are respectively located in the side airflow channels 96 and the bottom airflow channel 94. By installing the guide rail assemblies 70 in the side airflow channels 96 and the bottom airflow channel 94, the air flowing in the side airflow channels 96 and the bottom airflow channel 94 is used to dissipate heat from the guide rail assemblies 70, thereby improving the reliability of the guide rail assemblies 70.

[0144] Specifically, the guide rail assembly 70 is close to the inner pot 10. When the cooking device 100 is working, the inner pot 10 is usually at a relatively high temperature. The normal operation of the guide rail assembly 70 usually requires lubricating fluid. The high temperature causes the lubricating fluid to be quickly consumed or ineffective. The present application utilizes the air flowing in the side airflow channel 96 to dissipate heat from the guide rail assembly 70, so that the lubricating fluid always exerts its effect, thereby improving the reliability of the guide rail assembly 70.

[0145] As shown in FIG. 10 , specifically, the guide rail assembly 70 includes a guide rail 71 and a sliding member 72 . The sliding member 72 is suitable for sliding along the guide rail 71 . One of the guide rail 71 and the sliding member 72 is provided on the drawer 60 , and the other is provided on the inner container 10 .

[0146] As shown in Figure 6, in other embodiments, the inner pot 10 includes a first side panel 16, a second side panel 161 and a bottom panel 17, the first side panel 16 is arranged on one side of the cooking space 11, the second side panel 161 is arranged on the other side of the cooking space 11, the bottom panel 17 connects the first side panel 16 and the second side panel 161, and the bottom panel 17 is located at the bottom of the cooking space 11.

[0147] As shown in FIG10 , a guide rail assembly 70 is provided between the bottom of the drawer 60 and the bottom plate 17. By providing the guide rail assembly 70 between the bottom of the drawer 60 and the bottom plate 17, the guide rail assembly 70 can fully support the gravity of the drawer 60, reducing the strength requirement of the connection between the guide rail assembly 70 and the drawer 60.

[0148] In other embodiments, the inner pot 10 includes a first side panel 16, a second side panel 161 and a bottom panel 17, the first side panel 16 is arranged on one side of the cooking space 11, the second side panel 161 is arranged on the other side of the cooking space 11, the bottom panel 17 connects the first side panel 16 and the second side panel 161, and the bottom panel 17 is located at the bottom of the cooking space 11.

[0149] As shown in FIG10 , a guide rail assembly 70 is provided between the first side portion of the drawer 60 and the first side panel 16, and between the second side portion of the drawer 60 and the second side panel 161. Furthermore, a guide rail assembly 70 is provided between the bottom of the drawer 60 and the bottom panel 17. By providing the guide rail assembly 70 between the first side portion of the drawer 60 and the first side panel 16, between the second side portion of the drawer 60 and the second side panel 161, and between the bottom of the drawer 60 and the bottom panel 17, the multiple guide rail assemblies 70 jointly support the drawer 60, allowing the drawer 60 to carry more and heavier food.

[0150] As shown in FIG10 , in some embodiments, the cooking device 100 further includes a drawer driver 80 for driving the drawer 60 in and out of the cooking space 11. The drawer driver 80 and the microwave assembly 42 are located on different sides of the inner pot 10. Providing the drawer driver 80 to drive the drawer 60 in and out of the cooking space 11 improves the automation level of the cooking device 100.

[0151] The drawer driver 80 and the microwave assembly 42 are located on different sides of the inner container 10, fully utilizing the space surrounding the inner container 10. For example, the drawer driver 80 can be located on the right side of the inner container 10, with the microwave assembly 42 located on the upper side; or the drawer driver 80 can be located on the left side of the inner container 10, with the microwave assembly 42 located on the lower side. Of course, the drawer driver 80 can also be located on other sides of the inner container 10, which will not be detailed here.

[0152] Specifically, the drawer driving member 80 includes a push-pull motor and a push-pull rod. The push-pull rod is connected to the drawer member 60 . The push-pull motor is used to drive the push-pull rod to translate, so as to drive the drawer member 60 to enter and exit the cooking space 11 .

[0153] In some embodiments, the upper end of the side airflow channel 96 is connected to the top airflow channel 92 .

[0154] For example, air flows from the side air flow passages 96 to the top air flow passages 92 and is eventually discharged from the cooking device 100 through the air outlet 91 .

[0155] As shown in Figures 11 and 10, in some embodiments, the cooking device 100 further includes a food carrier 61 disposed within the cooking space 11. The inner pot 10 is provided with a microwave inlet 14, which corresponds to the center of the food carrier 61. By arranging the microwave inlet 14 to correspond to the center of the food carrier 61, the microwave inlet 14 can be aligned with the center of the food, thereby improving the uniformity of microwave heating.

[0156] It should be noted that in related art, the microwave inlet is located in the center of the cooking space. However, since the cooking space is relatively large, the user may not place the food in the center of the cooking space, resulting in less uniform microwave heating, uneven heating of different parts of the food, and poor cooking quality. However, the present application provides an ingredient carrier 61 for holding food, for example, the food carrier is a grill, and the microwave inlet 14 is aligned with the center of the grill, thereby improving the uniformity of microwave heating and the cooking quality.

[0157] [Corrected 13.12.2023 according to Rule 91] As shown in Figures 5 and 6, in some embodiments, the cooking device 100 further includes an air baffle 36. The air baffle 36 is disposed between the outer shell 90 and the inner pot 10 to separate a bottom air flow channel 94 from at least one side air flow channel 96. The air baffle 36 is provided with a second air inlet hole 361 for connecting the bottom air flow channel 94 and the side air flow channel 96. The provision of the air baffle 36 to separate the bottom air flow channel 94 from the side air flow channel 96 makes the boundary between the bottom air flow channel 94 and the side air flow channel 96 clearer, thereby preventing airflow turbulence.

[0158] The air baffle 36 is provided with a second air inlet 361, which connects the bottom airflow channel 94 and the side airflow channel 96. Air flows through both the bottom airflow channel 94 and the side airflow channel 96. For example, the second air inlet 361 connects the bottom airflow channel 94 and the left airflow channel; or the second air inlet 361 connects the bottom airflow channel 94 and the right airflow channel; or, the second air inlet 361 connects the bottom airflow channel 94 and the left airflow channel and the right airflow channel, respectively.

[0159] For example, the air in the bottom air flow channel 94 enters the side air flow channel 96 through the second air inlet hole 361 .

[0160] As shown in Figures 3 to 6, in some embodiments, the inner liner 10 is provided with a rear panel 19. The rear panel 19 cooperates with the outer shell 90 and the wind baffle 36 to separate the bottom airflow channel 94, the rear airflow channel 95, and the side airflow channel 96. The rear panel 19 is provided with a first connecting hole 191 and a second connecting hole 192. The first connecting hole 191 connects the bottom airflow channel 94 and the rear airflow channel 95, and the second connecting hole 192 connects the side airflow channel 96 and the rear airflow channel 95. By providing the rear panel 19 to separate the bottom airflow channel, the rear airflow channel 95, and the side airflow channel 96, the boundaries between the various channels are made clearer, avoiding airflow turbulence.

[0161] The rear panel 19 is provided with a first connecting hole 191, which connects the bottom airflow channel 94 and the rear airflow channel 95, allowing air to flow through both the bottom airflow channel 94 and the rear airflow channel 95. For example, the air in the bottom airflow channel 94 flows into the rear airflow channel 95 through the first connecting hole 191.

[0162] The rear panel 19 is provided with a second connecting hole 192, which connects the side airflow channel 96 and the rear airflow channel 95, allowing air to flow through both the side airflow channel 96 and the rear airflow channel 95. For example, air in the side airflow channel 96 flows into the rear airflow channel 95 through the second connecting hole 192.

[0163] In some embodiments, the inner pot 10 is provided with at least one heat dissipation area 162, which is connected to the air flow channel 99. By providing at least one heat dissipation area 162, the cooking space 11 in the inner pot 10 is cooled. At the same time, the heat dissipation area 162 is connected to the air flow channel 99, eliminating the need for a separate channel and improving utilization. In some specific embodiments, the heat dissipation area 162 and the first air inlet 111 are provided on different side walls of the inner pot 10. By providing the heat dissipation area 162 and the first air inlet 111 on different side walls of the inner pot 10, the air flow path is increased, allowing more water vapor and heat to be discharged. The heat dissipation area 162 and the first air inlet 111 can be adjacent side walls of the inner pot 10, or they can be opposite side walls.

[0164] As shown in Figures 1 to 4, in some specific embodiments, the heat dissipation region 162 and the first air inlet 111 are disposed on adjacent side walls of the inner liner 10. By disposing the heat dissipation region 162 and the first air inlet 111 on adjacent side walls of the inner liner 10, the air flow path is increased, allowing more water vapor and heat to be discharged.

[0165] For example, the first air inlet 111 is arranged on the rear wall of the inner liner 10, and the heat dissipation area 162 is arranged on the left wall of the inner liner 10; or, the first air inlet 111 is arranged on the rear wall of the inner liner 10, and the heat dissipation area 162 is arranged on the right wall of the inner liner 10; or, the first air inlet 111 is arranged on the left wall of the inner liner 10, and the heat dissipation area 162 is arranged on the rear wall of the inner liner 10; or, the first air inlet 111 is arranged on the right wall of the inner liner 10, and the heat dissipation area 162 is arranged on the rear wall of the inner liner 10; or, the first air inlet 111 is arranged on the upper wall of the inner liner 10, and the heat dissipation area 162 is arranged on the rear wall of the inner liner 10; or Alternatively, the first air inlet hole 111 is set on the upper wall of the inner liner 10, and the heat dissipation area 162 is set on the left wall of the inner liner 10; alternatively, the first air inlet hole 111 is set on the upper wall of the inner liner 10, and the heat dissipation area 162 is set on the right wall of the inner liner 10; alternatively, the first air inlet hole 111 is set on the rear wall of the inner liner 10, and the heat dissipation area 162 is set on the upper wall of the inner liner 10; alternatively, the first air inlet hole 111 is set on the left wall of the inner liner 10, and the heat dissipation area 162 is set on the upper wall of the inner liner 10; alternatively, the first air inlet hole 111 is set on the right wall of the inner liner 10, and the heat dissipation area 162 is set on the upper wall of the inner liner 10.

[0166] In other embodiments, the heat dissipation area 162 and the first air inlet 111 are disposed on opposite sidewalls of the inner liner 10. By disposing the heat dissipation area 162 and the first air inlet 111 on opposite sidewalls of the inner liner 10, the air flow path is increased, allowing more water vapor and heat to be discharged.

[0167] For example, the first air inlet 111 is set on the rear wall of the inner liner 10, and the heat dissipation area 162 is set on the front wall of the inner liner 10; or, the first air inlet 111 is set on the left wall of the inner liner 10, and the heat dissipation area 162 is set on the right wall of the inner liner 10.

[0168] In some embodiments, the inner tank 10 is provided with a side panel, the heat dissipation area 162 is arranged on the side panel, and a second air guide cover is also provided on the side panel. One end of the space in the second air guide cover is connected to the heat dissipation area 162, and the other end is connected to the air outlet 91.

[0169] As shown in Figures 1 to 6, specifically, the airflow channel 99 includes a top airflow channel 92, which is located at the top of the inner liner 10 and is connected to the air outlet 91. The inner liner 10 is provided with a fourth air inlet 182 for connecting the top airflow channel 92 and the space inside the second air guide cover.

[0170] For example, the inner container 10 is provided with a top plate 18 , and the fourth air inlet 182 is provided on the top plate 18 .

[0171] As shown in FIG1 and FIG12, in some embodiments, the cooking device 100 further includes a heating tube 41, which is disposed in the cooking space 11. The food is heated by the heating tube 41 and the microwave assembly 42. A variety of different heating methods enhance applicability.

[0172] The heating tube 41 emits infrared rays to heat the food; the microwave component 42 emits microwaves, which make the molecules inside the food resonate and the molecules rub against each other to generate heat.
