[0049] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0050] The cooking apparatus 100 of the present invention will now be described in conjunction with the accompanying drawings.

[0051] like Figure 1 , Figure 2 As shown, the cooking device 100 according to an embodiment of the present invention includes: a housing 90, an inner pot 10, and an air duct assembly 20.

[0052] The front of the box 90 is provided with a food loading and unloading port 15.

[0053] The inner liner 10 is located inside the box 90. The top wall of the inner liner 10 is provided with multiple spaced air circulation zones 123. Each air circulation zone 123 includes an air intake zone 12 and a return air zone 13 spaced apart in the front and rear directions.

[0054] The inner liner 10 is used to store food, the cooking device 100 cooks the food, and the food is placed or taken out through the food inlet 15 on the cabinet 90.

[0055] In this system, airflow outside the inner liner 10 enters the inner liner 10 through the air inlet area 12, and airflow inside the inner liner 10 is discharged through the air return area 13. For example, the air inlet area 12 is the area containing multiple perforated structures, and the air return area 13 is the area containing multiple perforated structures.

[0056] The air duct assembly 20 is located on the top wall of the inner liner 10. A plurality of air duct spaces 21 are provided between the air duct assembly 20 and the top wall of the inner liner 10. Each air duct space 21 is provided with a fan assembly 30 for guiding airflow.

[0057] Each air duct space 21 is provided in relation to the air circulation area 123. The air duct space 21 is used to guide air from the return air area 13 to the intake air area 12.

[0058] It is understood that the fan assembly 30 in the air duct space 21 disturbs the air to form airflow. The airflow enters the air duct space 21 from the inner liner 10 through the return air area 13. The airflow flows unidirectionally in the air duct space 21. The space inside the inner liner 10 is connected to the outside. The airflow enters the space inside the inner liner 10 from the outside. The airflow flows in the inner liner 10 and then enters the air duct space 21 through the return air area 13. The airflow enters the inner liner 10 from the air duct space 21 through the air intake area 12, forming a unidirectional circulation of airflow. This makes the heat distribution inside the inner liner 10 more even and improves the heating effect of food.

[0059] Among them, multiple air duct spaces 21 expand the influence range of airflow, making heat diffusion faster.

[0060] It should be noted that in related technologies, cooking devices use fans to turbulent air to create airflow. Typically, multiple fans are placed in the same space, and the interference between the multiple fans causes turbulence and wastes energy.

[0061] This application improves airflow turbulence, increases energy utilization, and further enhances heating effect by setting up multiple spaced air ducts 21. The multiple spaced air ducts 21 separate multiple fan assemblies 30, thereby improving airflow turbulence, increasing energy utilization, and further enhancing heating effect.

[0062] For example, there are two air duct spaces 21, each containing a fan assembly 30, thereby improving airflow turbulence. Alternatively, there are two air duct spaces 21, separating the four fan assemblies 30, with each air duct space 21 containing two fan assemblies 30, which also improves airflow turbulence. Or, there are three air duct spaces 21, separating the four fan assemblies 30, with one air duct space 21 containing two fan assemblies 30 and the other two air duct spaces 21 each containing one fan assembly 30, which also improves airflow turbulence.

[0063] According to the cooking apparatus 100 of the present invention, multiple fan assemblies 30 are separated by multiple spaced air duct spaces 21, which improves airflow turbulence, increases energy utilization, and further enhances heating effect. At the same time, the air duct spaces 21 guide air from the return air area 13 to the air intake area 12, and the air flows in one direction, thereby further improving airflow turbulence, increasing energy utilization, and further enhancing heating effect.

[0064] Specifically, cooking equipment 100 is any one of an air fryer, microwave oven, or oven.

[0065] like Figure 2 As shown, in some embodiments, each air circulation zone 123 includes a plurality of air intake zones 12 spaced apart in the front-back direction. By providing a plurality of air intake zones 12 arranged in the front-back direction, the range of influence in the front-back direction is expanded.

[0066] For example, each air circulation zone 123 includes two air intake zones 12; or, each air circulation zone 123 includes three air intake zones 12; or, each air circulation zone 123 includes four air intake zones 12.

[0067] In other embodiments, each air circulation zone 123 includes a plurality of air intake zones 12 spaced apart in the left-right direction. By providing a plurality of air intake zones 12 arranged in the left-right direction, the range of influence in the left-right direction is expanded.

[0068] For example, each air circulation zone 123 includes two air intake zones 12; or, each air circulation zone 123 includes three air intake zones 12; or, each air circulation zone 123 includes four air intake zones 12.

[0069] In some embodiments, the opening areas of the plurality of air intake areas 12 corresponding to each air circulation area 123 are different. By setting the opening areas of the plurality of air intake areas 12 corresponding to each air circulation area 123 to be different, the air intake volume at different positions in the internal space of the inner liner 10 is different, which adaptively meets the needs of food cooking and improves energy utilization.

[0070] For example, the opening area of ​​the air intake area 12 near the center of the internal space of the inner liner 10 is larger than the opening area of ​​the air intake area 12 far from the center, which improves energy utilization.

[0071] like Figure 2 As shown, in some embodiments, the opening area of ​​the air intake area 12, which is closest to the return air area 13, is the largest. By setting the opening area of ​​the air intake area 12, which is closest to the return air area 13, to the maximum, most of the heat is fully returned to the internal space of the inner liner 10, further improving energy utilization.

[0072] For example, the air intake area 12 is the area where multiple perforated structures are located. The opening area of ​​the air intake area 12 is the total area of ​​the multiple perforated structures. Setting a larger total area can increase the flow rate.

[0073] like Figure 2 As shown, in some embodiments, at least one air intake area 12 in each air circulation area 123 extends longitudinally in the front-to-back direction. By providing at least one air intake area 12 that extends longitudinally in the front-to-back direction, sufficient airflow is ensured in the front-to-back direction, resulting in a more even heat distribution within the inner liner 10.

[0074] like Figure 3 , Figure 4 As shown, in some embodiments, the air duct space 21 has a first portion 211 and a second portion 212, which are intersecting. 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 placing a portion of the air intake area 12 and the return air area 13 in the first portion 211, and the other 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 disturbed in a straight line, thereby expanding the range of influence.

[0075] like Figure 3 , Figure 4As shown, specifically, the first part 211 and the second part 212 are perpendicular to each other.

[0076] like Figure 3 , Figure 4 As shown, 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, the needs of different spaces are fully accommodated, and the utilization rate is improved.

[0077] like Figure 2 , Figure 3 , Figure 4 As shown, 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 setting the front side of the second portion 212 to extend 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 zones.

[0078] like Figure 1 , Figure 2 As shown, in some embodiments, the fan assembly 30 is positioned directly opposite the return air region 13 to guide air from the inner liner 10 into the air duct space 21. By positioning the fan assembly 30 directly opposite the return air region 13, air from the inner liner 10 is guided from the return air region 13 into the air duct space 21, expanding the influence range of the fan assembly 30 on the inner liner 10 and maximizing the effectiveness of the fan assembly 30.

[0079] Specifically, the fan assembly 30 is a centrifugal fan, which is positioned relative to the return air area 13. The centrifugal fan draws air from the inner liner 10 to form an airflow, increasing its impact on the inner liner 10. It can be understood that the air inlet of the centrifugal fan faces the return air area 13, thereby drawing air from the inner liner 10.

[0080] In other embodiments, the fan assembly 30 is disposed between the return air region 13 and the intake air region 12 to guide the air of the inner liner 10 from the return air region 13 into the air duct space 21.

[0081] Specifically, the fan assembly 30 is an axial flow fan, which is located between the return air area 13 and the air intake area 12, so that the airflow flows unidirectionally within the air duct space 21 and draws air from the inner liner 10.

[0082] like Figures 1 to 5As shown, in some embodiments, each fan assembly 30 includes a drive motor 31 and a fan blade 32. The drive motor 31 is connected to the fan blade 32 to drive the fan blade 32 to rotate. The fan blade 32 is located within the air duct space 21, and the drive motor 31 is located outside the air duct space 21. By placing the fan blade 32 within the air duct space 21 and the drive motor 31 outside the air duct space 21, airflow is avoided. Compared to related technologies where the drive motor is placed within the air duct space and affects airflow, the airflow within the air duct space 21 is smoother in this application.

[0083] 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 intake air area 12. It can be understood that the airflow leaves the inner liner 10 through the return air area 13, enters the air duct space 21 through the air duct inlet, and exits the air duct space 21 through the air duct outlet, enters the inner liner 10 through the intake air area 12.

[0084] like Figure 2 , Figure 3 As shown, in some embodiments, the air duct assembly 20 includes a first outer cover 22 and a partition 23. The first outer cover 22 is fixed to the top wall of the inner liner 10 and covers multiple return air areas 13 and multiple inlet air areas 12. The partition 23 is disposed inside the first outer cover 22 to separate multiple air duct spaces 21. By setting the first outer cover to cover multiple inlet air areas 12 and multiple return air areas 13, and separating multiple air duct spaces 21 by the partition 23, the number of parts is reduced, and assembly is easier.

[0085] Understandably, the multiple air duct spaces 21 separated by the separator 23 are all connected to the air intake area 12 and the air return area 13.

[0086] like Figure 2 , Figure 3 As shown, in some specific embodiments, a single fan assembly 30 is correspondingly provided in a single air duct space 21. The single fan assembly 30 is set in a single air duct space 21, which is different from the scheme of multiple fans being set in the same space in related technologies. This avoids the generation of turbulence, further improves energy utilization, and improves heating effect.

[0087] In some embodiments, the partition 23 is a heat-insulating material. By setting the partition 23 to be a heat-insulating material, the partition 23 divides multiple air duct spaces 21, while preventing heat conduction between adjacent air duct spaces 21, thus further ensuring even heating.

[0088] like Figure 2 , Figure 3As shown, in some specific embodiments, the separator 23 is fixed to the first outer cover 22. By fixing the separator 23 to the first outer cover 22, the assembly of the cooking device 100 is facilitated.

[0089] In some other embodiments, the separator 23 is fixed to the inner liner 10 for easy positioning.

[0090] like Figure 2 , Figure 3 As shown, in some specific embodiments, a first heat-insulating cover 221 is provided on the first outer cover 22. The first heat-insulating cover 221 is disposed on the first outer cover 22 and located on the side of the first outer cover 22 away from the inner liner 10. By providing the first heat-insulating cover 221 on the side of the first outer cover 22 away from the inner liner 10, heat is confined within the air duct space 21, avoiding heat waste and improving energy utilization.

[0091] like Figure 4 As shown, in some embodiments, the air duct assembly 20 includes a plurality of spaced-apart second outer cover members 24, each second outer cover member 24 being fixed to the outer side wall of the inner liner 10, and each second outer cover member 24 and the inner liner 10 cooperating to define an air duct space 21. By providing a plurality of spaced-apart second outer cover members 24, the structure becomes simpler and clearer, and assembly is easier.

[0092] It should be noted that the air duct space 21 is connected to the air intake area 12 and the air return area 13, realizing unidirectional airflow circulation.

[0093] like Figure 4 As shown, in some specific embodiments, a single fan assembly 30 is correspondingly provided in a single air duct space 21. The single fan assembly 30 is set in a single air duct space 21, which is different from the scheme of multiple fans being set in the same space in related technologies. This avoids the generation of turbulence, further improves energy utilization, and improves heating effect.

[0094] like Figure 4 As shown, in some specific embodiments, a second heat-insulating cover 241 is provided on the second outer cover 24. The second heat-insulating cover 241 is disposed on the second outer cover 24 and located on the side of the second outer cover 24 opposite to the inner liner 10. By providing the second heat-insulating cover 241 on the side of the second outer cover 24 opposite to the inner liner 10, heat is confined within the air duct space 21, avoiding heat waste and improving energy utilization.

[0095] like Figure 5As shown, in some embodiments, the cooking appliance 100 further includes a drawer assembly 60, which forms a food-carrying space. The drawer assembly 60 is detachably mounted on the inner liner 10 via a food access port 15. By providing the drawer assembly 60 to carry food, and by engaging the drawer assembly 60 with the inner liner 10, compared to related technologies where the food-carrying space is fixed inside the cooking appliance, this application facilitates the placement and removal of food.

[0096] It should be noted that the drawer assembly 60 and the inner liner 10 can be pulled out together, allowing the cooking equipment 100 to be embedded in the cabinet of the furniture, making it suitable for different working environments.

[0097] In some specific embodiments, the drawer assembly 60 is adapted to enter and exit the inner liner 10 by means of translation and / or rotation.

[0098] In other words, the drawer assembly 60 can move in and out of the inner liner 10 by sliding; or, the drawer assembly 60 can move in and out of the inner liner 10 by rotating; or, the drawer assembly 60 can move in and out of the inner liner 10 by both sliding and rotating.

[0099] like Figure 6 As shown, in some embodiments, the housing 90 has a first heat dissipation area 91, the inner liner 10 has a second heat dissipation area 162, and a heat dissipation duct 92 is provided between the housing 90 and the inner liner 10, which is connected to the first heat dissipation area 91 and the second heat dissipation area 162 respectively. By providing the first heat dissipation area 91 and the second heat dissipation area 162, and by providing the heat dissipation duct 92 to connect the first heat dissipation area 91 and the second heat dissipation area 162 respectively, the inner liner 10 can effectively dissipate heat and reduce humidity.

[0100] It is understandable that when the cooking equipment 100 is working, the temperature inside the inner pot 10 rises. However, the temperature of the inner pot 10 needs to be kept within a certain range and cannot be too high. This application sets up a first heat dissipation area 91 and a second heat dissipation area 162, and sets up a heat dissipation duct 92 to connect the first heat dissipation area 91 and the second heat dissipation area 162 respectively, so that the inner pot 10 can dissipate heat and reduce humidity.

[0101] Specifically, the first heat dissipation area 91 is the area where the perforated structure is located, and the second heat dissipation area 162 is the area where the perforated structure is located. Airflow can pass through the perforated structure and carry away heat and moisture.

[0102] The first heat dissipation area 91 is the area where multiple hole structures are located, and the second heat dissipation area 162 is the area where multiple hole structures are located.

[0103] like Figure 6As shown, in some embodiments, the first heat dissipation area 91 is located on the front surface of the housing 90. By placing the first heat dissipation area 91 on the front surface of the housing 90, it is convenient to exhaust high-temperature airflow from the front of the cooking device 100.

[0104] For example, the cooking appliance 100 is placed inside a cabinet, and the first heat dissipation area 91 located on the front surface of the cabinet 90 exhausts air to the cabinet outlet, keeping the inside of the cabinet dry.

[0105] In some embodiments, the second heat dissipation area 162 is located in at least one of the left and right sidewalls of the inner liner 10.

[0106] For example, the second heat dissipation area 162 is located on the left side wall of the inner liner 10; or, the second heat dissipation area 162 is located on the right side wall.

[0107] In some embodiments, the second heat dissipation area 162 is located at the upper part of the inner liner 10. By placing the second heat dissipation area 162 at the upper part of the inner liner 10, it can be understood that hot air automatically rises, thereby improving the heat dissipation effect.

[0108] In some specific embodiments, a wind guide shroud is provided on the second heat dissipation area 162, the wind guide shroud restricts part of the heat dissipation airflow, and another part of the heat dissipation airflow is defined between the housing 90 and the inner liner 10, which communicates with the wind guide shroud.

[0109] like Figure 1 As shown, in some embodiments, the cooking device 100 further includes a heating component 40, which is disposed in the inner pot 10 and is used to heat the food inside the inner pot 10.

[0110] like Figure 1 , Figure 5 As shown, in some embodiments, the heating assembly 40 includes a heating element 41 and a microwave assembly 42. The inner pot 10 has a cooking space 11, the heating element 41 is disposed in the cooking space 11, the inner pot 10 is provided with a microwave inlet 14, and the microwave assembly 42 is used to generate microwaves and deliver microwaves toward the cooking space 11 through the microwave inlet 14. The microwave assembly 42 and the air duct assembly 20 are located on the same side of the inner pot 10. Heating food through the heating element 41 and the microwave assembly 42 provides multiple different heating methods, enhancing applicability.

[0111] The heating element 41 emits infrared rays to heat the food; the microwave component 42 emits microwaves, which cause the molecules inside the food to resonate and generate heat through friction between the molecules.

[0112] like Figure 2 , Figure 8As shown, the inner pot 10 is equipped with a microwave inlet 14. Microwaves generated by the microwave component 42 enter the cooking space 11 through the microwave inlet 14 to heat the food in the cooking space 11. The microwave component 42 and the air duct component 20 are located on the same side of the inner pot 10. With both the microwave component 42 and the air duct component 20 on the same side of the inner pot 10, they occupy less space, making the cooking equipment 100 more compact overall.

[0113] In related technologies, the fan device and microwave generator are installed on the upper and lower sides of the cavity, respectively. In order to install the fan device, a whole layer of space must be set up above the cavity, and in order to install the microwave generator, a whole layer of space must be set up below the cavity. At the same time, when assembling cooking appliances, the fan device and microwave generator must be installed on the two sides of the cavity, which makes assembly difficult.

[0114] like Figure 1 , Figure 2 As shown in this application, the microwave component 42 and the air duct component 20 are located on the same side of the inner pot 10. That is to say, they can occupy only one side of the space of the inner pot 10. The functional components of the cooking equipment 100, such as the microwave component 42 and the air duct component 20, are more concentrated and have a compact structure. At the same time, the concentrated functional components are convenient to install.

[0115] like Figure 2 As shown, in some embodiments, the air duct assembly 20 is arranged around the microwave assembly 42. By arranging the air duct assembly 20 around the microwave assembly 42, the airflow within the air duct assembly 20 has a wider range of influence.

[0116] In some embodiments, the cooking device 100 has a first operating mode and a second operating mode. In the first operating mode, the microwave component 42 and at least one fan component 30 are working. In the second operating mode, the heating element 41 and at least one fan component 30 are working. That is, the fan component 30 is working in both the first and second operating modes, making full use of the fan component 30 and reducing the number of parts.

[0117] In other words, the cooking device 100 has at least two working modes, namely the first working mode and the second working mode.

[0118] In the first working mode, the cooking device 100 operates with the microwave component 42 and at least one fan component 30. The microwave component 42 generates microwaves to heat the food in the cooking space 11, and the airflow generated by the fan component 30 flows over the food, heating it more evenly and improving the cooking effect.

[0119] The microwave component 42 operates with at least one fan component 30, that is, the microwave component 42 can operate with one fan component 30, two fan components 30, or three fan components 30.

[0120] In some embodiments, the microwave component 42 and the fan component 30 operate simultaneously, for example, the microwave component 42 and the fan component 30 are turned on at the same time, or the microwave component 42 and the fan component 30 are both operating within a certain time period.

[0121] In other embodiments, the microwave component 42 and the fan component 30 work alternately, that is, the microwave component 42 works for a period of time, then the fan component 30 works for a period of time, and then the microwave component 42 works for a period of time again, so that the fan component 30 makes the heat distribution more even.

[0122] In the second working mode, the cooking device 100 is in operation, with the heating element 41 and at least one fan assembly 30 working. The heating element 41 generates infrared rays to heat the food, and the airflow generated by the fan assembly 30 flows in the cooking space 11, making the temperature in the cooking space 11 more uniform and improving the heating uniformity.

[0123] The heating element 41 works with at least one fan assembly 30. That is, the heating element 41 can work with one fan assembly 30, two fan assemblies 30, or three fan assemblies 30.

[0124] In some embodiments, the heating element 41 and the fan assembly 30 work simultaneously, for example, the heating element 41 and the fan assembly 30 are turned on at the same time, or the heating element 41 and the fan assembly 30 are both working within a certain period of time.

[0125] In other embodiments, the heating element 41 and the fan assembly 30 work alternately, that is, the heating element 41 works for a period of time, then the fan assembly 30 works for a period of time, and then the heating element 41 works for a period of time again, so that the fan assembly 30 makes the heat distribution more even.

[0126] like Figure 5 , Figure 8 As shown, in some embodiments, the cooking apparatus 100 further includes a rotatable stirring element 50, which is correspondingly disposed on the microwave inlet 14. By correspondingly distributing the stirring element 50 on the microwave inlet 14, the stirring element 50 can stir the microwaves, thereby distributing the microwaves more evenly to various parts of the cooking space 11.

[0127] like Figure 7As shown, in some specific embodiments, the stirring element 50 is disposed in the cooking space 11. The stirring element 50 is provided with a stirring motor 51, the output end of which passes through the microwave component 42 and is connected to the stirring element 50 to drive the stirring element 50 to rotate.

[0128] More specifically, the stirring motor 51 and the fan assembly 30 are aligned in a first direction, which improves the compactness of the structure. For example, the first direction is the vertical direction.

[0129] In some embodiments, both the microwave assembly 42 and the fan assembly 30 are located on the top wall of the inner liner 10.

[0130] In other words, the microwave inlet 14 is located on the top wall of the inner liner 10, which simplifies the process of the inner liner 10. For example, it eliminates the need to fix a ceramic plate on the inner liner 10, thus optimizing the process.

[0131] In some embodiments, the top wall of the inner liner 10 is also provided with a splash guard, which corresponds to the microwave inlet 14 to prevent oil from splashing into the microwave inlet 14.

[0132] Specifically, the splash guard and the top wall of the inner liner 10 together define a stirring space, and the stirring component 50 is located in the stirring space. The splash guard prevents oil from splashing into the microwave inlet 14 and also prevents oil from splashing onto the stirring component 50, thus reducing the amount of cleaning work later.

[0133] Specifically, the splash guard is made of quartz, which can be penetrated by microwaves, thus utilizing the inherent properties of quartz to achieve a splash-proof effect.

[0134] like Figure 8 As shown, in some embodiments, the cooking appliance 100 further includes a guide assembly 70, which guides the drawer assembly 60 as it moves in and out of the cooking space 11. The guide assembly 70 and the heating assembly 40 are located on different sides of the inner liner 10, and the guide assembly 70 and the microwave assembly 42 are also located on different sides of the inner liner 10. By using the guide assembly 70 to guide the drawer assembly 60 in and out of the cooking space 11, the movement of the drawer assembly 60 is made more stable.

[0135] In this design, the guide assembly 70 and the heating assembly 40 are located on different sides of the inner liner 10. For example, the guide assembly 70 can be located on the left and right sides of the inner liner 10, while the heating assembly 40 can be located on the upper side of the inner liner 10, making full use of the space. Alternatively, the guide assembly 70 can be located on the lower side of the inner liner 10, and the heating assembly 40 on the upper side. Or, the guide assembly 70 can be located on other sides of the inner liner 10, and the heating assembly 40 can be located on a side of the inner liner 10 that is distinct from the guide assembly 70.

[0136] In this design, the guide component 70 and the microwave component 42 are located on different sides of the inner liner 10. For example, the guide component 70 can be located on the left and right sides of the inner liner 10, while the microwave component 42 can be located on the upper side of the inner liner 10, making full use of the space. Of course, the guide component 70 can also be located on the lower side of the inner liner 10, while the microwave component 42 can be located on the upper side of the inner liner 10. Alternatively, the guide component 70 can be located on other sides of the inner liner 10, while the microwave component 42 can be located on a side of the inner liner 10 that is distinct from the guide component 70.

[0137] like Figure 2 As shown, in some embodiments, the inner pot 10 includes a first side plate 16, a second side plate 161 and a bottom plate 17. The first side plate 16 is disposed on one side of the cooking space 11, the second side plate 161 is disposed on the other side of the cooking space 11, and the bottom plate 17 connects the first side plate 16 and the second side plate 161, and the bottom plate 17 is located at the bottom of the cooking space 11.

[0138] like Figure 8 As shown, guide components 70 are provided between the first side of the drawer assembly 60 and the first side panel 16, and between the second side of the drawer assembly 60 and the second side panel 161. By providing guide components 70 between the first side of the drawer assembly 60 and the first side panel 16, and between the second side panels 161 and the second side panels 161, multiple guide components 70 support the drawer assembly 60, making the operation of the drawer assembly 60 more stable.

[0139] like Figure 8 As shown, specifically, the guide assembly 70 includes a guide rail 71 and a slider 72, the slider 72 being adapted to slide along the guide rail 71, one of the guide rail 71 and the slider 72 being disposed in the drawer assembly 60, and the other being disposed in the inner liner 10.

[0140] like Figure 2 As shown, in some other embodiments, the inner pot 10 includes a first side plate 16, a second side plate 161 and a bottom plate 17. The first side plate 16 is disposed on one side of the cooking space 11, the second side plate 161 is disposed on the other side of the cooking space 11, and the bottom plate 17 connects the first side plate 16 and the second side plate 161, and the bottom plate 17 is located at the bottom of the cooking space 11.

[0141] like Figure 8 As shown, a guide component 70 is provided between the bottom of the drawer assembly 60 and the base plate 17. By providing the guide component 70 between the bottom of the drawer assembly 60 and the base plate 17, the guide component 70 can fully support the weight of the drawer assembly 60, reducing the strength requirements of the connection between the guide component 70 and the drawer assembly 60.

[0142] In some other embodiments, the inner pot 10 includes a first side plate 16, a second side plate 161 and a bottom plate 17. The first side plate 16 is disposed on one side of the cooking space 11, the second side plate 161 is disposed on the other side of the cooking space 11, and the bottom plate 17 connects the first side plate 16 and the second side plate 161, and the bottom plate 17 is located at the bottom of the cooking space 11.

[0143] like Figure 8 As shown, guide components 70 are provided between the first side and the first side panel 16 of the drawer assembly 60, and between the second side and the second side panel 161 of the drawer assembly 60. Additionally, a guide component 70 is provided between the bottom of the drawer assembly 60 and the bottom plate 17. By providing guide components 70 between the first side and the first side panel 16, between the second side and the second side panel 161 of the drawer assembly 60, and between the bottom of the drawer assembly 60 and the bottom plate 17, multiple guide components 70 collectively support the drawer assembly 60, enabling the drawer assembly 60 to carry more and heavier food items.

[0144] like Figure 8 As shown, in some embodiments, the cooking appliance 100 further includes a drawer drive 80, which drives the drawer assembly 60 in and out of the cooking space 11. The drawer drive 80 and the heating assembly 40 are located on different sides of the inner liner 10. By setting the drawer drive 80 to drive the drawer assembly 60 in and out of the cooking space 11, the automation level of the cooking appliance 100 is improved.

[0145] The drawer drive 80 and the heating assembly 40 are located on different sides of the inner liner 10, making full use of the surrounding space of the inner liner 10. For example, the drawer drive 80 is located on the right side of the inner liner 10, and the heating assembly 40 is located on the upper side of the inner liner 10; or, the drawer drive 80 is located on the left side of the inner liner 10, and the heating assembly 40 is located on the lower side of the inner liner 10; of course, the drawer drive 80 can also be located on other sides of the inner liner 10, which will not be elaborated here.

[0146] Specifically, the drawer drive unit 80 includes a push-pull motor and a push-pull rod. The push-pull rod is connected to the drawer assembly 60. The push-pull motor is used to drive the push-pull rod to move horizontally, so as to drive the drawer assembly 60 into and out of the cooking space 11.

[0147] like Figure 1 , Figure 2 , Figure 5 and Figure 8As shown, in some embodiments, the inner liner 10 includes a top plate 18 located at the top of the cooking space 11. The top wall is the outward-facing side of the top plate 18. A top-side space is formed between the side of the top plate 18 facing away from the cooking space 11 and the cabinet 90. At least a portion of the microwave assembly 42 and the air duct assembly 20 are located in the top-side space, and the end of the drawer assembly 60 facing the top plate 18 is an open end. By placing at least a portion of the microwave assembly 42 and the air duct assembly 20 in the top-side space, and making the side of the drawer assembly 60 facing the top plate 18 an open end, both hot air and microwaves can heat food more quickly.

[0148] like Figure 8 As shown, at least a portion of the microwave component 42 and the air duct component 20 are located in the top side space, while the end of the drawer component 60 facing the top plate 18 is set as an open end, which facilitates the inflow of hot air and the entry of microwaves.

[0149] In some embodiments, the inner liner 10 includes a rear panel 19, which is disposed opposite to the opening of the cooking space 11. A rear space is formed between the side of the rear panel 19 away from the cooking space 11 and the housing 90, and a portion of the microwave assembly 42 is located in the rear space.

By setting the second heat dissipation area 162, the heat and water vapor inside the cooking device are guided out of the cooking space 11, thereby improving the heat dissipation capacity.

[0153] like Figures 10 to 14 As shown, in some specific embodiments, the inner liner 10 includes a side panel, and a second heat dissipation area 162 is disposed on the side panel to improve heat dissipation capacity. For example, the second heat dissipation area 162 is disposed on the first side panel 16.

[0154] like Figures 10 to 14As shown, more specifically, the inner liner 10 includes a top plate 18, the top plate 18 is provided with a second air inlet 182, and the side plate is provided with an air guide hood. One end of the space inside the air guide hood is connected to the second heat dissipation area 162, and the other end is connected to the second air inlet 182, so as to guide the air in the cooking space 11 to flow to the aforementioned top and side space.

[0155] like Figures 10 to 14 As shown, more specifically, the housing 90 is provided with an air inlet 93 and a first heat dissipation area 91. A heat dissipation duct 92 is provided between the outer side walls of the housing 90 and the inner liner 10.

[0159] In some embodiments, the inner liner 10 includes a top plate 18, a first side plate 16, a second side plate 161, a bottom plate 17, and a rear plate 19. The top plate 18 is located at the top of the cooking space 11, and a top-side space is formed between the side of the top plate 18 away from the cooking space 11 and the housing 90. The bottom plate 17 is located at the bottom of the cooking space 11, and a bottom-side space is formed between the side of the bottom plate 17 away from the cooking space 11 and the housing 90. The first side plate 16 is disposed on one side of the cooking space 11, and the second side plate 161 is disposed on the other side of the cooking space 11.

The waveguide 422 and the air duct assembly 20 are located in the top space. The magnetron 421 is located in the rear space. The drawer drive 80 is located in the right space.

[0162] This application makes full use of the top side space by placing the waveguide 422 and the air duct assembly 20 in the top side space, making the overall structure of the cooking device 100 thinner in the height direction. At the same time, the magnetron 421 is placed in the rear side space and the drawer drive 80 is placed in the right side space, making rational use of each part of the space.

[0163] like Figure 5 , Figure 8 As shown, in some embodiments, the drawer assembly 60 includes: a drawer body 63 and a roller 64. The roller 64 is located at the bottom of the drawer body 63 and is adapted to roll into contact with the bottom wall of the inner liner 10.

[0164] More specifically, the roller 64 is located at the end of the drawer piece away from the opening of the inner liner 10.

[0165] like Figure 8 As shown, 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 storage space is located inside the drawer body 631. The drawer door 632 is suitable for opening or closing the opening.

[0166] In some specific embodiments, the guide assembly 70 further includes: a guide rail 71, which is disposed on both sides of the cooking space 11, and a guide rail connecting plate is provided on the drawer body 631, which is connected to the guide rail 71.

[0167] like Figure 8 As shown, in some specific embodiments, the drawer door 632 is provided with a handle 6321 and a viewing window, and the box 90 is provided with a control panel, with the drawer door 632 flush with the control panel.

[0168] In some embodiments, the inner liner 10 includes a top plate 18, a first side plate 16, a second side plate 161, and a bottom plate 17. The top plate 18 is located at the top of the cooking space 11, and a top-side space is formed between the side of the top plate 18 away from the cooking space 11 and the housing 90.

[0170] The drawer assembly 60 is adapted to enter and exit the cooking space 11 by manual drive, and at least a portion of the microwave assembly 42 is located in the top or bottom space of the air duct assembly 20.

[0171] like Figure 5 , Figure 8 As shown, in some embodiments, the cooking device 100 further includes a food carrier 61, which is disposed within the cooking space 11. The inner liner 10 is provided with a microwave inlet 14, which corresponds to the center of the food carrier 61. By setting 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, thus improving the uniformity of microwave heating.

[0172] It should be noted that in related technologies, the microwave inlet is located in the center of the cooking space. However, the cooking space is relatively large, and the food placed by the user may not be in the center of the cooking space, resulting in low uniformity of microwave heating, uneven heating of different parts of the food, and poor cooking effect. In contrast, this application improves the uniformity of microwave heating and enhances the cooking effect by setting up a food carrier 61 to support the food, such as a grill rack, with the microwave inlet 14 corresponding to the center of the grill rack.
