Description

Technical Field

[0001] The present invention relates to the field of cooking devices, and in particular to a cooking device with a dish reservation function. Background Art

[0002] A steam-bake combination machine is a combination cooking device that integrates both baking and steaming functions, offering single-steaming, single-bake, and combined steam-bake functions. For example, there are the Chinese invention patents for "A Steam-Bake Combination Machine" with application number CN202111526610.1 (publication number CN114287789A) and "A Steam-Bake Inner Tank Structure and Steam-Bake Combination Machine" with patent number ZL202122199759.5 (authorization publication number CN216293752U).

[0003] Traditional steam-bake ovens only offer real-time cooking and lack a reservation function, significantly impacting the user experience. Chinese invention patent application number CN201910879631.8 (publication number CN110537834A), titled "A Steam Oven," discloses a steam oven, specifically comprising: a steam-bake chamber comprising a shell enclosing the steam-bake space; a heating assembly for heating the shell; and a refrigeration unit positioned in contact with the shell, capable of absorbing heat from the shell in a cooling state and a constant temperature state in which it stops absorbing heat from the shell. When the user activates the reservation function, the food to be steamed and baked is placed in the relatively enclosed steam-bake chamber. The refrigeration unit then switches to a cooling state, absorbing heat from the shell, lowering the shell's temperature and thus the temperature inside the steam-bake chamber, preventing the food from spoiling while waiting for the scheduled cooking time. Although the steam oven described in this patent has a reservation function, it only allows for single-dish reservations; multiple dishes cannot be reserved. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a cooking device with a dish reservation function that can realize the reservation of multiple dishes in response to the existing technology.

[0005] The second technical problem to be solved by the present invention is to provide a cooking device with a dish reservation function that is convenient for taking and placing dishes in view of the existing technology.

[0006] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a cooking device with a dish reservation function, comprising an inner pot, characterized in that an openable and closable dish delivery port is provided on the inner pot, and also comprises a dish delivery device for delivering dishes to be cooked into the inner pot through the above-mentioned dish delivery port or delivering cooked dishes out of the inner pot through the above-mentioned dish delivery port, and the dish delivery device has at least one container for placing dishes.

[0007] Furthermore, the food delivery device includes

[0008] A frame, comprising a bracket for placing the above-mentioned container;

[0009] The food delivery position corresponds to the food delivery opening mentioned above;

[0010] A first food delivery mechanism, configured to set the bracket and deliver the container on the bracket to the food delivery position; and

[0011] The second food delivery mechanism is used to deliver the container at the food delivery position into the inner pot. In this way, the food outside the inner pot can be smoothly delivered into the inner pot for cooking through the food delivery device.

[0012] Furthermore, the frame also includes a circular rotating table, with the dish delivery position located at its center. The rotating table is rotatable circumferentially about the dish delivery position. At least two first dish delivery mechanisms are provided, each spaced apart along the circumference of the rotating table, and the brackets correspond one-to-one with the first dish delivery mechanisms. This allows for the simultaneous placement of multiple dishes on the dish delivery device, making it easier to schedule the cooking of multiple dishes. Furthermore, each container can be conveniently transported to the dish delivery position, facilitating the delivery of each dish.

[0013] Furthermore, each of the first food delivery mechanisms includes a mounting bracket fixed to the outer circumference of the rotating platform, a first screw, and a first drive motor. The first screw is rotatably mounted on the mounting bracket and extends radially along the rotating platform. One end of the first screw is fixed to the output shaft of the first drive motor. A nut seat is threadedly connected to the first screw, forming a threaded transmission pair with the first screw, and the bracket is fixed to the nut seat. In this way, each first food delivery mechanism can conveniently transport the containers on it to the food delivery position.

[0014] Furthermore, each of the brackets is detachably connected to the container thereon, and the food delivery position is provided with a magnetic locating member that forms a magnetic connection with the corresponding container. In the food delivery state, the food delivery position is aligned with the food delivery opening, and the corresponding container is positioned at the food delivery position by the magnetic locating member and detached from the corresponding bracket. This facilitates the transfer of uncooked food from the bracket to the food delivery position, ensures the container is securely placed at the food delivery position, and also facilitates the transfer of cooked food from the food delivery position to the bracket.

[0015] Furthermore, a rotating motor is provided inside the rotating platform, a rotating gear is mounted on the output shaft of the rotating motor, and a rotating ring gear meshing with the rotating gear is provided on the inner circumference of the rotating platform, thereby realizing automatic rotation of the rotating platform.

[0016] Furthermore, the rotating platform includes an annular rotating base and a cylindrical fixed base. The rotating ring gear is mounted on the inner circumference of the rotating base. The fixed base is closed at one end and has a radially extending sliding edge on the outer circumference of the other end. The rotating base has a circumferentially recessed groove on the inner side thereof for the sliding edge to fit into and slide circumferentially. This allows the rotating base to rotate smoothly relative to the fixed base.

[0017] Furthermore, the edge of the open end of the fixed seat extends radially outward along the circumferential direction to form a mounting edge, and circular mounting seats are provided at circumferential intervals on the top surface of the mounting edge. Each mounting seat is respectively embedded with a ball that can roll relative to the mounting seat in which it is located, and the peripheral edge of the mounting edge is bent outward along the circumferential direction to form the aforementioned sliding edge. The end of the rotating seat opposite the fixed seat is recessed outward along the circumferential direction to form a first groove. The side surface of the first groove is recessed along the circumferential direction to form the aforementioned sliding groove, and the end surface of the first groove is recessed along the circumferential direction to form a second groove for the exposed end of each ball to be embedded and roll. On the one hand, a stable rotational connection is achieved between the rotating seat and the fixed seat, and on the other hand, the rotating seat can rotate more smoothly relative to the fixed seat.

[0018] Furthermore, the food delivery port is opened on the bottom wall of the inner container, the second food delivery mechanism includes a telescopic cylinder vertically arranged below the inner container, and the magnetic positioning member is an electromagnet block fixed to the top of the piston rod of the telescopic cylinder. Each of the above containers is a horizontally arranged tray, and the bottom surface of each container is respectively connected to the corresponding bracket in an upper and lower plug-in manner.

[0019] Furthermore, when the nut holder corresponding to each container moves to the innermost end of the first screw on which it is located, the center of the bottom surface of each container is magnetically connected to the magnetic positioning member, and the magnetic attraction between the two is greater than the insertion force between the container and the corresponding bracket. This makes it easier to transfer the food to be cooked from the corresponding bracket to the food transfer position, thereby facilitating the transfer of the food to be cooked into the inner pot.

[0020] Furthermore, each of the brackets is equipped with a gravity sensor for measuring the weight of the food in the corresponding container, so that the food to be cooked placed in each container can be weighed conveniently and the cooking program can be set according to the obtained food weight to improve the cooking effect.

[0021] Furthermore, each container has at least two different shapes, and includes a recognition system capable of identifying containers of different shapes. The recognition system is electrically connected to the controller of the cooking device and includes a camera for photographing each container. Thus, the recognition system can identify different dishes based on the different shapes of the containers and activate the corresponding cooking mode.

[0022] Furthermore, a baffle is horizontally provided on the food delivery opening for shielding the food delivery opening. The baffle can rotate around a rotation center axis extending vertically and located on one side of the food delivery opening, and has at least two states:

[0023] In the first state, the baffle completely covers the food delivery opening; in the second state, the baffle opens the food delivery opening, thereby realizing the opening and closing control of the food delivery opening.

[0024] Furthermore, the edge of the food delivery opening extends vertically downward along the circumference to form a food delivery ring. A notched ring is circumferentially formed at the upper end of the food delivery ring for the baffle to be inserted into. A vertically extending rotating shaft and an opening and closing motor are respectively provided on one side of the food delivery ring. A transmission gear is horizontally mounted on the output shaft of the opening and closing motor. The central axis of the rotating shaft constitutes the aforementioned rotational center axis, and an opening and closing gear is horizontally mounted on the rotating shaft. One end of the opening and closing gear is fixed to the edge of the baffle, while the other end meshes with the transmission gear. In this way, the opening and closing of the food delivery opening can be controlled by the opening and closing motor driving the baffle to rotate eccentrically relative to the notched ring.

[0025] Furthermore, a steaming and grilling rack is horizontally disposed in the inner pot, and the steaming and grilling rack has an openable food delivery window for the food delivery device to deliver the containers to the steaming and grilling rack. The food delivery window facilitates placing the dishes to be cooked on the steaming and grilling rack, or facilitates removing the cooked dishes from the steaming and grilling rack through the food delivery window.

[0026] Furthermore, a first door and a second door are horizontally disposed above the food delivery window, respectively, and include an opening and closing control mechanism for driving the first door and the second door to move relative to or apart from each other. When the first door and the second door are in a relative movement and joined together, the food delivery window is closed; when the first door and the second door are in a state of moving apart and having the distance therebetween maximized, the food delivery window is opened. In this way, the opening and closing of the food delivery window on the steaming and grilling rack can be controlled by the movement of the first door and the second door.

[0027] Furthermore, the first and second doors have a first notch and a second notch at opposite ends, respectively. When the first and second doors are in the assembled state, the first and second notches are assembled to form a through hole for the piston rod of the telescopic cylinder to pass through.

[0028] Furthermore, the opening and closing control mechanism includes a driving motor, a second screw, a first screw sleeve and a second screw sleeve, the second screw extends along the setting direction of the first frame door and the second frame door, and one end of the second screw is rotatably connected to the steaming and grilling rack and the other end is fixed to the output shaft of the driving motor, the first screw sleeve and the second screw sleeve are respectively threadedly connected to the second screw, and the first screw sleeve and the second screw sleeve respectively form a threaded transmission pair with the second screw, and the first screw sleeve is fixed to the first frame door and the second screw sleeve is fixed to the second frame door.

[0029] When the first and second doors are joined, the opposing ends of the first and second screw sleeves abut against each other, while when the distance between the first and second doors is maximized, the distance between the opposing ends of the first and second screw sleeves is maximized, thereby effectively enabling relative movement or separation of the first and second doors.

[0030] Furthermore, a food storage chamber is provided below the inner pot, and the food delivery device is horizontally arranged in the food storage chamber. A food delivery opening is provided on the top wall of the food storage chamber, which is vertically opposite to the food delivery opening of the inner pot. In this way, dishes to be cooked or cooked can be placed in the food storage chamber, thereby better realizing the scheduled cooking of dishes.

[0031] Furthermore, the front side of the food storage chamber is opened to form a food taking opening and a food storage door is rotatably installed to cover the food taking opening. The food storage chamber is provided with a pushing mechanism for pushing the food delivery device forward horizontally so that the corresponding container extends out of the food taking opening, thereby making it easier for users to take and put food.

[0032] Furthermore, the ejection mechanism includes a push rod motor mounted at the rear end of the inner cavity of the above-mentioned vegetable storage chamber, with the rod portion of the push rod motor extending forward and backward and fixed to the above-mentioned rotating platform. In this way, the push rod motor pushes the rotating platform to push the vegetable delivery device into and out of the vegetable storage chamber, making it more convenient for users to take and put dishes.

[0033] Furthermore, a left and right slide rail extending forward and backward are fixed to the left and right sides of the inner cavity of the food storage chamber, respectively, and a left slider and a right slider are fixed to the rotating platform, respectively. The left slider is embedded in the left slide rail, and the right slider is embedded in the right slide rail. The left and right sliders can slide forward and backward synchronously along the corresponding slide rails, thereby enabling the food delivery device to be smoothly pushed in and out.

[0034] Compared with the prior art, the advantages of the present invention are: an openable and closable food delivery port is provided on the inner pot, and the food delivery device is used to deliver the food into the inner pot through the food delivery port for cooking, and the food delivery device has at least one container for placing the food. Compared with the traditional reservation method (the food to be cooked is directly placed in the inner pot), the food to be cooked in the present invention is placed outside the inner pot, and the food is delivered to the inner pot during cooking. Therefore, the cooking of multiple dishes can be reserved as needed, and the use of the dish reservation function is more convenient, which improves the user experience.

[0050] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0051] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0052] like Figures 1 to 15 As shown, a cooking device (such as a steamer, oven, or steam-oven oven) includes a box body 1, an inner pot 11 arranged in the box body 1, and a door body 18 that can cover the front opening of the inner pot 1111.

[0053] Furthermore, the inner pot 11 is provided with an openable and closable dish delivery port 111, and also includes a dish delivery device 2 for transferring dishes to be cooked into the inner pot 11 through the dish delivery port 111, or transferring cooked dishes out of the inner pot 11 through the dish delivery port 111. The dish delivery device 2 includes at least one container 50 for placing dishes, and in this embodiment, there are four containers 50. Compared with the traditional reservation method (in which the dishes to be cooked are placed directly in the inner pot 11), the dishes to be cooked in the present invention are placed outside the inner pot 11 and are transferred into the inner pot 11 during cooking. Therefore, the cooking of multiple dishes can be scheduled as needed, making the reservation function more convenient and improving the user experience.

[0054] The above-mentioned food delivery opening 111 can be set in a variety of positions on the inner pot 11, such as the bottom wall, top wall or side wall. Preferably, in this embodiment, the above-mentioned food delivery opening 111 is opened on the bottom wall of the inner pot 11. In addition, the dishes to be cooked can be placed directly outside the box 1 of the cooking device, or a space specifically for storing dishes can be designed inside the box 1. In this embodiment, preferably, a food storage chamber 10 is provided under the inner pot 11, and the above-mentioned food delivery device 2 is horizontally arranged in the food storage chamber 10, and a food delivery opening 121 is opened on the top wall of the food storage chamber 10, which is directly opposite to the food delivery opening 111 of the inner pot 11. Specifically, a lower mounting plate 12 is horizontally provided below the inner tank 11, and the lower mounting plate 12 and the lower portion of the box body 1 enclose the above-mentioned vegetable storage chamber 10. The above-mentioned vegetable delivery port 121 is opened on the lower mounting plate 12, and the front side of the above-mentioned vegetable storage chamber 10 is opened with a vegetable taking port 100 and a vegetable storage door 101 for covering the vegetable taking port 100 is rotatably installed. Figure 4 shown.

[0055] Further, if Figure 3 As shown, the food delivery port 121 of the lower mounting plate 12 is connected to the food delivery port 111 via a vertically extending food delivery ring 1111, thereby facilitating the delivery of food between the food delivery port 121 and the food delivery port 111. Furthermore, to facilitate the opening and closing control of the food delivery port 111, a notch ring 11111 is circumferentially provided at the upper end of the food delivery ring 1111 for the baffle 13 to be embedded in. A vertically extending rotating shaft 14 and an opening and closing motor 15 are provided on one side of the food delivery ring 1111. A transmission gear 16 is horizontally mounted on the output shaft of the opening and closing motor 15. The central axis of the rotating shaft 14 constitutes the aforementioned rotational center axis, and an opening and closing gear 17 is horizontally mounted on the rotating shaft 14. One end of the opening and closing gear 17 is fixed to the edge of the baffle 13 and the other end is meshed with the transmission gear 16. Thus, by driving the eccentric rotation of the baffle 13 relative to the notched ring 11111 by the opening and closing motor 15, the opening and closing of the food delivery port 111 can be controlled. Furthermore, in the present invention, the connection between the food delivery port 111 and the food delivery port 121 allows the gas in the inner pot 11 to be introduced into the food storage chamber 10, thereby achieving heat preservation and moisture retention for the food placed in the food storage chamber 10 (especially cooked food). Simultaneously, by controlling the movement of the baffle 13 relative to the notched ring 11111, the actual opening area of ​​the food delivery port 111 can be controlled, thereby regulating the temperature and humidity within the food storage chamber 10. In this embodiment, the food delivery ring 1111 is formed by the circumferential edge of the food delivery port 111 extending vertically downward and connecting circumferentially to the circumferential edge of the food delivery port 121.

[0056] Further, if Figure 2 and Figure 3As shown, a steaming grill 6 is placed in the inner pot 11, in order to smoothly place the dishes to be cooked on the steaming grill 6, or remove the cooked dishes from the steaming grill 6. In this embodiment, as shown in FIG. Figures 13-15 As shown, the steaming and grilling rack 6 has a dish delivery window 63 that can be opened and closed and through which the dish delivery device 2 delivers each of the containers 50 to the steaming and grilling rack 6. The dish delivery window 63 facilitates placing dishes to be cooked on the steaming and grilling rack 6, or facilitates removing cooked dishes from the steaming and grilling rack 6 through the dish delivery window 63. Specifically, a first frame door 61 and a second frame door 62 are horizontally disposed above the dish delivery window 63, respectively, and further includes an opening and closing control mechanism 7 for driving the first frame door 61 and the second frame door 62 to move relative to or apart from each other. Furthermore, when the first frame door 61 and the second frame door 62 move relative to each other and engage, the dish delivery window 63 is closed. When the first frame door 61 and the second frame door 62 move apart and the distance between them is maximized, the dish delivery window 63 is opened. In this way, the opening and closing control of the dish delivery window 63 on the steaming and grilling rack 6 can be achieved through the movement of the first frame door 61 and the second frame door 62. Furthermore, the opening and closing control mechanism 7 includes a drive motor 71, a second screw rod 72, a first screw sleeve 73, and a second screw sleeve 74. The second screw rod 72 extends along the direction in which the first and second doors 61 and 62 are arranged. One end of the second screw rod 72 is rotatably connected to the steaming and grilling rack 6, while the other end is fixed to the output shaft of the drive motor 71. The first screw sleeve 73 and the second screw sleeve 74 are respectively threadedly connected to the second screw rod 72, and the first screw sleeve 73 and the second screw sleeve 74 respectively form a threaded transmission pair with the second screw rod 72. In addition, the first screw sleeve 73 is fixed to the first door 61, while the second screw sleeve 74 is fixed to the second door 62. When the first and second doors 61 and 62 are in a spliced ​​state, the opposite ends of the first screw sleeve 73 and the second screw sleeve 74 abut against each other. When the distance between the first and second doors 61 and 62 is at its maximum, the distance between the opposite ends of the first screw sleeve 73 and the second screw sleeve 74 is at its maximum. Thus, the relative movement or separation movement of the first frame door 61 and the second frame door 62 can be better achieved. Preferably, the opposite ends of the first frame door 61 and the second frame door 62 have a first notch 611 and a second notch 621, respectively. When the first frame door 61 and the second frame door 62 are in the assembled state, the first notch 611 and the second notch 621 are assembled to form a through hole 631 for the piston rod of the telescopic cylinder 41 to pass through. In addition, in this embodiment, preferably, a guide rail 64 extending along the moving direction of the first frame door 61 and the second frame door 62 is fixed to the upper edge of the steaming and grilling rack 6. The first screw sleeve 73 fixes one end of the first frame door 61, and the other end of the first frame door 61 is embedded in the guide rail 64 and can slide back and forth along the guide rail 64. At the same time, the second screw sleeve 74 is fixed to one end of the second frame door 62, and the other end of the second frame door 62 is embedded in the guide rail 64 and can slide back and forth along the guide rail 64.

[0057] Furthermore, in order to smoothly transfer the food in the food storage chamber 10 into the inner pot 11 for cooking, the food delivery device 2 includes a frame 21, a food delivery position corresponding to the food delivery port 111, a first food delivery mechanism 3, and a second food delivery mechanism 4. The frame 21 includes a bracket 211 for placing the container 50, the first food delivery mechanism 3 is used to set the bracket 211 and to transport the container 50 on the bracket 211 to the food delivery position, and the second food delivery mechanism 4 is used to deliver the container 50 on the food delivery position into the inner pot 11. Furthermore, the frame 21 also includes a circular rotating table 5, the food delivery position is set at the center of the rotating table 5, and the rotating table 5 can rotate circumferentially with the food delivery position as the center, and the first food delivery mechanism 3 is at least two and is arranged outside the rotating table 5 at intervals along the circumference of the rotating table 5, and the brackets 211 correspond one-to-one to the first food delivery mechanism 3. In this way, multiple dishes can be placed on the food delivery device 2 at the same time, which makes it more convenient to realize the cooking reservation of multiple dishes, and each container 50 can be conveniently transported to the food delivery position, thereby facilitating the delivery of each dish. In addition, by setting up a rotating table 5, it is convenient to place dishes on the food delivery device 2, or to take dishes off the food delivery device 2.

[0058] Specifically, each of the first food delivery mechanisms 3 includes a mounting bracket 31 fixed to the outer circumference of the rotating platform 5, a first screw 32, and a first drive motor 33. The first screw 32 is rotatably mounted on the mounting bracket 31 and extends radially along the rotating platform 5. One end of the first screw 32 is fixed to the output shaft of the first drive motor 33. A nut seat 34 is threadedly connected to the first screw 32. The nut seat 34 and the first screw 32 form a threaded transmission pair, and the bracket 211 is fixed to the nut seat 34. In this way, each first food delivery mechanism 3 can conveniently transport the container 50 thereon to the food delivery position. Each bracket 211 is detachably connected to the container 50 thereon, and the food delivery position is provided with a magnetic positioning member 42 that can form a magnetic connection with the corresponding container 50. In the food delivery state, the food delivery position is vertically aligned with the food delivery port 111. The corresponding container 50 is positioned at the food delivery position by the magnetic positioning member 42 and is separated from the corresponding bracket 211. This facilitates the transfer of the dish to be cooked from the support 211 to the dish delivery position, ensures that the container 50 is securely placed at the dish delivery position, and facilitates the transfer of the cooked dish from the dish delivery position to the support 211. Preferably, guide sleeves 342 extending along the length of the corresponding first screw rod 32 are fixed on both sides of each nut seat 34, and the mounting bracket 31 is fixed with guide rods 311 corresponding to each guide sleeve 342. Each guide rod 311 extends along the length of the corresponding first screw rod 32, and each guide sleeve 342 can move back and forth along the corresponding guide rod 311.

[0059] Furthermore, to enable automatic rotation of the rotating platform 5, a rotating motor 53 is disposed inside the rotating platform 5. A rotating gear 531 is mounted on the output shaft of the rotating motor 53, and a rotating ring gear 511 is disposed on the inner circumference of the rotating platform 5, meshing with the rotating gear 531. Specifically, the rotating platform 5 includes an annular rotating base 51 and a cylindrical fixed base 52. The rotating ring gear 511 is disposed on the inner circumference of the rotating base 51. The fixed base 52 has a closed lower end and a radially extending sliding edge 521 circumferentially disposed on the outer periphery of the upper end. A sliding groove 512 is circumferentially recessed on the inner side of the rotating base 51, into which the sliding edge 521 is inserted and slides circumferentially. This allows the rotating base 51 to rotate smoothly relative to the fixed base 52. Preferably, the edge of the upper port of the fixed seat 52 extends radially outward along the circumferential direction to form a mounting rim 522. Circular mounting seats 523 are circumferentially spaced apart on the top surface of the mounting rim 522. Each mounting seat 523 is embedded with a ball 524 capable of rolling relative to its respective mounting seat 523. The circumferential edge of the mounting rim 522 bends and extends circumferentially outward and upward to form the aforementioned sliding edge 521. The inner side of the lower end of the rotating seat 51 is circumferentially recessed outward to form a first groove 51a. The side surfaces of the first groove 51a are circumferentially recessed to form the aforementioned sliding groove 512. The top surface of the first groove 51a is circumferentially recessed to form a second groove 51b in which the exposed ends of the balls 524 are embedded and roll. This ensures a stable rotational connection between the rotating seat 51 and the fixed seat 52 and allows the rotating seat 51 to rotate more smoothly relative to the fixed seat 52.

[0060] Furthermore, the second food delivery mechanism 4 includes a telescopic cylinder 41 vertically arranged below the inner tank 11, and the telescopic cylinder 41 is installed on the inner bottom surface of the box body 1, and the magnetic positioning part 42 is an electromagnet block fixed to the top of the piston rod of the telescopic cylinder 41, so that the container 50 can be easily loaded or unloaded at the food delivery position by turning on and off the power of the electromagnet block.

[0061] Furthermore, each of the above-mentioned containers 50 is a horizontally arranged disk, and the bottom surface of each container 50 is respectively plugged and connected with the corresponding bracket 211. Specifically, a vertically extending plug post 51 is protruded from the bottom surface of each container 50, and a vertically extending slot 341 is opened on each nut seat 34 for the corresponding plug post 51 to be inserted. The size of each slot 341 matches the corresponding plug post 51. In addition, when the nut seat 34 corresponding to each container 50 moves to the innermost end of the first screw 32 where it is located, the middle part of the bottom surface of each container 50 is magnetically connected to the above-mentioned magnetic positioning member 42, and the magnetic attraction force between the two is greater than the plug-in connection force between the container 50 and the corresponding bracket 211. This makes it easier to transfer the dishes to be cooked from the corresponding bracket 211 to the dish transfer position, thereby facilitating the delivery of the dishes to be cooked at the dish transfer position into the inner pot 11 for cooking.

[0062] Furthermore, each bracket 211 is mounted with a gravity sensor 2111 for measuring the weight of the food in the corresponding container 50. This allows for convenient weighing of the food to be cooked in each container 50, and allows for the cooking program to be set based on the weight, thus improving cooking results. Preferably, each container 50 has at least two different shapes (four in this embodiment) and includes a recognition system (not shown) capable of identifying containers 50 of different shapes. This recognition system is electrically connected to a controller (not shown) of the cooking device and includes a camera for capturing images of each container 50. This recognition system can identify different dishes based on the shape of the container 50 and activate the corresponding cooking mode. In this embodiment, the camera is preferably positioned on the bottom surface of the lower mounting plate 12, adjacent to the food delivery port 121. This allows for better imaging of the containers 50 in the food delivery position and reduces the impact of the high temperature of the inner pot 11 on camera performance.

[0063] To further facilitate the removal of dishes from the storage cavity, the storage chamber 10 is provided with an ejection mechanism 8 for pushing the dish delivery device 2 horizontally forward, causing the corresponding container 50 to extend from the dish removal opening 100. Specifically, the ejection mechanism 8 includes a push rod motor 81 mounted at the rear end of the inner cavity of the storage chamber 10. The rod portion of the push rod motor 81 extends forward and backward and is fixed to the fixed base 52 of the rotating table 5. In this way, the push rod motor 81 pushes the rotating table 5 to push the dish delivery device 2 into and out of the storage chamber 10, making it more convenient for users to remove and place dishes. Preferably, a left slide rail 91 and a right slide rail 92 extending forward and backward are fixed to the left and right sides of the inner cavity of the above-mentioned food storage chamber 10, respectively, and a left slider 54 and a right slider 55 are fixed to the above-mentioned rotating table 5, respectively. In addition, the left slider 54 is embedded in the above-mentioned left slide rail 91 and the right slider 55 is embedded in the above-mentioned right slide rail 92, and the left slider 54 and the right slider 55 can slide forward and backward synchronously along the corresponding slide rails. Thereby, the food delivery device 2 can be pushed in and out smoothly. In this embodiment, the two sides of the bottom of the above-mentioned fixed seat 52 are fixed to the above-mentioned left slider 54 by a left connecting rod 541, and are fixed to the above-mentioned right slider 55 by a right connecting rod 551.

[0064] The working process of the present invention is as follows:

[0065] The food storage chamber 10 is opened, and the food delivery device 2 extends out of the food storage chamber 10. The user puts the food into the corresponding container 50 (in conjunction with the rotation of the turntable 5). The ejection mechanism 8 pushes the food delivery device 2 into the food storage chamber 10, and the food storage door 101 closes the food storage cavity again.

[0066] The first food delivery mechanism 3 corresponding to the dish to be cooked pushes the bracket 211 on which the dish to be cooked is placed to the dish delivery position, and the container 50 containing the dish to be cooked is magnetically connected to the magnetic positioning member 42 at the dish delivery position. The opening and closing motor 15 drives the baffle 13 to rotate and open the dish delivery port 111. At the same time, the opening and closing control mechanism 7 opens the dish delivery window 63 on the steaming and grilling rack 6. The second food delivery mechanism 4 delivers the dish at the dish delivery position into the inner pot 11 through the dish delivery port 111, and then delivers it to the steaming and grilling rack 6 through the dish delivery window 63. The piston rod of the telescopic cylinder 41 resets, and the dish delivery window 63 and the dish delivery port 111 are closed respectively, and the cooking device enters the cooking state.

[0067] Among them, when the container 50 is located below the food delivery port 121 (that is, located at the food delivery position), the camera shoots the container 50, the recognition system recognizes the shape of the container 50 and transmits it to the controller, and the controller starts the corresponding cooking mode according to the shape of the container 50.

[0068] When the first dish is cooked, the opening and closing motor 15 drives the baffle 13 to open the food delivery opening 111. The piston rod of the telescopic cylinder 41 extends through the food delivery opening 111 into the inner pot 11. The magnetic positioning member 42 on the piston rod then magnetically connects with the container 50 through the opening 631 on the steaming and grilling rack 6. The opening and closing control mechanism 7 opens the food delivery window 63 on the steaming and grilling rack 6. The piston rod retracts, and the container 50 is transferred back to the food storage chamber 10 through the food delivery opening 111. If a second dish is to be cooked, the above operation is repeated.

[0069] When all the dishes are cooked, they are temporarily stored in the food storage chamber 10. During the storage process, the actual opening area of ​​the food delivery port 111 can be adjusted by controlling the rotation of the baffle 13, thereby adjusting the temperature and humidity inside the food storage chamber 10.
