The feeding bin 26 is movable and has an initial position (see FIG3 ), a material receiving position (see FIG4 ), and a material feeding position (see FIG7 ). The initial position is located between the material receiving position and the material feeding position. When in the initial position, the feeding bin 26 first descends to the material receiving position before receiving and feeding the materials. The material feeding position is located above the material receiving position. The feeding bin 26 rises and falls between the material receiving and material feeding positions. When in the material receiving position, the feeding bin 26 is connected to the storage bin outlet 25, and when in the material feeding position, it is connected to the discharge port 23. Specifically, the top of the feeding hopper 26 defines a feeding hopper inlet 27, and the bottom defines a feeding hopper outlet 28. The bottom wall of the feeding hopper 26 is tilted so that the feeding hopper inlet 27 is higher than the feeding hopper outlet 28 in the direction of gravity, allowing materials to flow easily toward the feeding hopper outlet 28 under the action of gravity. Optionally, the feeding hopper inlet 27 is normally open, while the feeding hopper outlet 28 is normally closed, opening only when rice is needed. The feeding hopper 26 has a preset volume, and each time it delivers a fixed amount of material, it functions as a metering device. The number of times the feeding hopper 26 delivers material can be set to quantify the amount of ingredients to be cooked. It should be noted that the term "top" as used herein refers to the top portion of the device, which occupies a certain proportion in the height direction. For example, the top of the feeding hopper 26 is not limited to its top wall but also includes the top portion of its side walls. Similarly, the term "bottom" refers to the bottom portion of the device, which occupies a certain proportion in the height direction. For example, the bottom of the feeding hopper 26 is not limited to its bottom wall but also includes the bottom portion of its side walls. To enable the feeding hopper 26 to be raised and lowered, the feed bin 22 also includes a feeding hopper drive mechanism, which is disposed within the feed bin housing 29. In one embodiment, as shown in the illustrated embodiment, the feeding hopper drive mechanism is a screw drive mechanism 30, which includes a screw 31 and a screw drive device 32 (see FIG4 ). The screw 31 is arranged vertically and rotates about its own axis. The feeding hopper 26 is sleeved on the screw 31 and is raised and lowered by the rotation of the screw 31.The screw drive device 32 can be located at the bottom or top of the material bin 22 and is drivingly connected to one end of the screw 31. Optionally, the screw drive device 32 is a motor, which can be arranged vertically. Alternatively, the feed bin drive mechanism can be another type of linear drive mechanism. The material bin 22 also includes a material bin discharge portion 33 having a discharge channel 80. OThe bin discharge portion 33 is disposed on the bin housing 29. The discharge port 23 of the bin 22 is formed in the bin discharge portion 33. When the feed hopper 26 is in the feeding position, it communicates with the discharge port 23 via the discharge passage 80. The bin discharge portion 33 is movable between an initial position (see Figures 3 to 6) and a discharge position (see Figure 7) in which it interfaces with the feed port 7. In the initial position, the bin discharge portion 33 is located within the bin 22 and extends from the bin 22 in the discharge position. The feed hopper 26 can push the bin discharge portion 33 from the initial position to the discharge position. Figure 6 shows the feed hopper 26 contacting the bin discharge portion 33 in the initial position when it is raised to the pushing position. To transport material from the feed inlet 7 to the washing bin 13, a feeding device 34 and a feeding drive 100 are also provided within the pot lid 5 (see Figure 27). The feeding device 34 comprises a device body 35 and a movable feeding assembly 36. The device body 35 forms a receiving cavity within which the feeding assembly 36 is disposed. The feeding drive 100 can be located outside the device body 35 to drive the feeding assembly 36. In one example, the feeding assembly 36 is a belt drive assembly including a movable conveyor belt 37. In other examples not shown, the feeding assembly 36 is a horizontal push assembly including a movable push plate, or a screw drive assembly including a rotatable screw. Alternatively, the feeding drive 100 is a motor, which can be arranged horizontally. Returning to Figures 1 and 2, the cooking appliance 1 also includes a fresh water tank 38 and a dirty water tank 39. A water inlet passage can be formed between the clean water tank 38 and the washing bin 13, for example, by providing a water inlet pipeline and a water pump. The washing bin 13 has a water inlet at the top. Optionally, the water inlet and the feed inlet 18 are the same opening. When adding water, the water pump can be turned on, and water in the clean water tank 38 is supplied to the washing bin 13 via the water inlet pipeline. The amount of water added can be controlled by controlling the water pump on-time. The cooking appliance 1 also includes a sewage tank 39. A drainage passage can be formed between the sewage tank 39 and the washing bin 13. Specifically, the washing bin 13 has a sewage outlet, specifically, the washing bin body 15, through which sewage after washing is discharged.For example, the pot lid 5 is provided with a drainage pipe 41 connected to the drainage outlet of the material washing bin 13. The sewage outlet 42 of the drainage pipe 41 is located above and corresponds to the sewage inlet 43 of the sewage tank 39. Sewage within the material washing bin 13 can flow into the sewage tank 39 via the drainage pipe 41, the sewage outlet 42 of the drainage pipe 41, and the sewage inlet 43 of the sewage tank 39 for collection. Sewage flows directly into the sewage tank 39 under the action of gravity, eliminating the need for a power device such as a drainage pump. As shown in FIG8 , the various components of the cooking appliance 1 can be arranged as follows: the pot assembly 2 is arranged side by side with and connected to the material tank 22 in the left-right direction, specifically the pot body 3 is connected to the material tank 22; the clean water tank 38 is arranged side by side with and connected to the material tank 22 in the front-to-back direction; and the sewage tank 39 is provided within the pot body 3, for example, side by side with and connected to the pot body 3 in the front-to-back direction. As an example, in the illustrated embodiment, the material bin 22 is located on the left side of the pot assembly 2, the clean water tank 38 is located behind the material bin 22, and the dirty water tank 39 is located in front of the pot 3. The cooking appliance 1 of this embodiment is constructed as a single unit, making it easy to access. Both the material bin 22 and the clean water tank 38 are higher than the pot lid 5. This allows for greater utilization of the height space for storing materials and clean water, and facilitates the gravity transfer of materials and / or clean water to the pot lid 5. Optionally, the material bin 22 is detachably connected to the pot 3. This allows for easy removal, allowing it to be taken to a material source for loading, facilitating operation and facilitating maintenance and replacement. The clean water tank 38 is detachably mounted on the material bin 22. This allows for easy removal, allowing it to be taken to a water source for refilling, facilitating operation and facilitating maintenance and replacement. The sewage tank 39 is detachably mounted on the pot body 3. This allows for easy emptying of the sewage, which can then be cleaned. Furthermore, as shown in Figure 8, the pot lid 5 comprises a pot lid body 8 and a removable cover 9 located below the pot lid body 8. The removable cover 9 is detachably attached to the pot lid body 8. This allows the user to simply remove the removable cover 9 when cleaning is desired, making it simple and convenient. The removable cover 9 can be mounted over the material washing bin 13, specifically over the material washing bin body 15.The removable lid 9 is provided with positioning slots 10 at intervals, and the pot lid body 8 is provided with corresponding positioning posts 11. Alternatively, the pot lid body 8 may be provided with positioning slots 10 and the removable lid 9 with positioning posts 11. After the removable lid 9 is installed, the positioning posts 11 are inserted into the positioning slots 10 to achieve positioning. For example, there are three positioning slots 10 arranged in a circular array, and correspondingly, there are three positioning posts 11 arranged in a circular array. In a preferred embodiment, a sewage pipe 41 is provided on the removable lid 9, allowing it to be removed from the pot lid 5 along with the removable lid 9, facilitating cleaning of the interior of the sewage pipe 41. A material washing bin 13 can be connected to the removable lid 9 so that it can be removed from the pot lid 5 along with the removable lid 9. This solution allows the washing bin 13 to be removed together with the removable lid 9, making it easier for the user to disassemble the washing bin 13 and eliminating the need to remove the components that require cleaning. This facilitates cleaning the washing bin 13 and prevents residual materials from becoming moldy and infested with insects over time. In the illustrated embodiment, the sewage pipe 41, washing bin 13, and removable lid 9 are constructed as a single unit. When the user wishes to clean these components, they can be removed in one go, simplifying the disassembly process and improving the user experience. The sewage tank 39 is detachably connected to the pot body 3. For example, the pot body 3 is provided with a base on which the sewage tank 39 is removably mounted. A cooperating retaining structure is provided between the pot body 3 and the sewage tank 39, ensuring more secure attachment of the sewage tank 39. This solution makes the sewage tank 39 easily accessible for emptying and cleaning the wastewater. The material bin 22 also includes a material bin cover 44. The material bin housing 29 has a top opening, and the material bin cover 44 covers the top opening. The cooking appliance 1 also includes a control unit that can be connected to various electronic control devices in the cooking appliance 1 to control their operation. These electronic control devices include a screw drive device 32, a material feed drive device 100, a material washing drive device 40, a water pump, etc. The cooking appliance 1 also has an operation interface and, optionally, a wireless module that can connect to a remote device such as a mobile phone via wireless network / Bluetooth. The user can set cooking parameters, such as the amount of material and cooking time, through the operation interface or the remote device. Pressing the confirmation button automatically initiates cooking operations such as measuring, adding ingredients, adding water, washing ingredients, and cooking.Default parameters can also be set to complete cooking with a single click. The feeding process of the cooking appliance 1 according to the preferred embodiment will be described with reference to Figures 3 to 7. As shown in Figure 3, the cooking appliance 1 is in its initial state. The pot lid 5 and the washing bin lid 16 are both in the closed position, and the feeding bin 26 and the material bin discharge port 33 are both in their initial positions. The storage bin outlet 25 and the feeding bin outlet 28 are both closed. When feeding is desired, the screw drive 32 is activated and rotates the screw 31, causing the feeding bin 26 to descend from its initial position to the receiving position. As shown in Figure 4, the cooking appliance 1 is in the receiving state, with the feeding bin 26 in the receiving position. The feeding bin inlet 27 is now connected to the storage bin outlet 25, and material in the storage bin 24 flows into the feeding bin 26. The feeding bin 26 remains in the receiving position for a predetermined period of time to allow it to fill up. The predetermined time can be determined based on factors such as the effective volume of the feed bin 26 and the size of the storage bin outlet 25. After the predetermined time has elapsed, the screw drive device 32 drives the screw 31 to rotate in the opposite direction, causing the feed bin 26 to rise, for example, to the raised position shown in FIG5 . At this point, the feed bin inlet 27 is located above the storage bin outlet 25, and the storage bin outlet 25 can be closed. The feed bin 26 is then driven upward to the pushed position shown in FIG6 . At this point, the feed bin 26 contacts the material bin discharge portion 33. As the feed bin 26 continues to rise, it pushes the material bin discharge portion 33 from its initial position to the discharge position. As shown in FIG7 , the cooking appliance 1 is in the discharge state, with the feed bin 26 in the feeding position. The feed bin outlet 28 is now in communication with the material bin discharge portion 33, and the material in the feed bin 26 is delivered to the feed inlet 7 of the pot lid 5 via the material bin discharge portion 33. The feed bin 26 remains in the feeding position for a predetermined time to allow the material to completely flow out of it. The feed bin 26 is then driven down to its initial position, while the feed bin outlet 28 is closed and the material bin discharge portion 33 retracts to its initial position. If further feeding is required, the above steps can be repeated. Material flowing in from the feed inlet 7 of the pot lid 5 falls into the receiving cavity of the feed device 34. The feed drive 100 is activated and drives the feed assembly 36, such as the conveyor belt 37, to move. At this point, the cooking appliance 1 is in the feeding state, with the material being conveyed by the feed assembly 36 into the washing bin 13.After the material has been completely delivered to the washing bin 13, the feed drive 100 is closed, completing the material delivery. Furthermore, as shown in Figures 9 and 10, the bottom of the storage bin 24 is provided with a first closure member 45 that closes the storage bin outlet 25. The first closure member 45 is movable between a closed position, blocking the storage bin outlet 25, and an open position, opening the storage bin outlet 25. The primary portion of the first closure member 45 is plate-shaped, and therefore can also be referred to as a baffle. By opening the first closure member 45, the feed bin 26 can communicate with the storage bin outlet 25 when in the material receiving position. In different embodiments, the first closure member 45 can exist in different states when the feed bin 26 is in the material receiving position. In one embodiment, the first closure member 45 remains open when the feed bin 26 is in the material receiving position. In another embodiment, the first closure member 45 is initially closed and then moved to an open state when the feed bin 26 is in the material receiving position. Specifically, when the feeding bin 26 is at the material receiving position, there is a period of time during which the first closure member 45 is open, allowing the feeding bin 26 to communicate with the material storage bin outlet 25. This period of time can be the entire time the feeding bin 26 is at the material receiving position, or a portion of it. Specifically, in one example, as the feeding bin 26 moves to the material receiving position, the first closure member 45 is simultaneously opened, allowing the feeding bin 26 to communicate directly with the material storage bin outlet 25. In another example, the first closure member 45 is not opened immediately after the feeding bin 26 reaches the material receiving position, or for a period of time. Only after the feeding bin 26 remains at the material receiving position is the first closure member 45 opened, allowing the feeding bin 26 to communicate with the material storage bin outlet 25. Regarding the opening method of the first closure member 45, as shown in the illustrated embodiment, the feeding bin 26 can push the first closure member 45 open, thereby utilizing the movement of the feeding bin 26 to open the material storage bin outlet 25. Alternatively, a separate actuator can be provided to push the first closure member 45 open. The following detailed description uses the illustrated embodiment as an example. The feeding bin 26 is provided with a first pusher 48 and has a first actuation position located between the receiving position and the feeding position. Specifically, the first actuation position is located above and proximate to the receiving position. Figure 9 shows the feeding bin 26 in the first actuation position.When the feeding bin 26 is in the first actuated position, the first pusher 48 abuts the first closure member 45 in the closed position. When the feeding bin 26 descends from the first actuated position to the material receiving position, the first pusher 48 pushes the first closure member 45 from the closed position to the open position, thereby opening the storage bin outlet 25. When the first closure member 45 is in the open position, the first pusher 48 remains in contact with the first closure member 45, preventing it from returning to its original position. In this embodiment, the movement of the feeding bin 26 can be controlled to drive the first closure member 45 to open the storage bin outlet 25. During the material receiving state, the first closure member 45 remains in the open position, thereby maintaining the storage bin outlet 25 open and facilitating automatic material receiving. After material receiving is complete, the feeding bin 26 ascends. At this point, the first pusher 48 no longer applies a thrust to the first closure member 45, allowing it to return to its original position. This eliminates the need for an electric drive device to move the first closure member 45, saving manufacturing and operating costs. It also reduces the number of parts in the cooking appliance 1, simplifies the product structure, saves installation space, and facilitates product miniaturization. The storage bin 24 has a vertically extending storage bin sidewall 46. The storage bin outlet 25 is located on this sidewall 46. In other words, the storage bin outlet 25 is a vertically arranged opening facing the feed bin 26. The first closure member 45 is vertically movable, with its main portion parallel to the storage bin sidewall 46. The open position of the first closure member 45 is located below its closed position. This arrangement allows the movement of the first closure member 45 to align with that of the feed bin 26, allowing them to move up and down synchronously. This makes opening the first closure member 45 easier and simplifies the configuration. In the illustrated embodiment, the first closure member 45 is entirely located outside the storage bin outlet 25 on the side facing the feed bin 26 and is in contact with the storage bin sidewall 46. The first closure member 45 can block the storage bin outlet 25 from the outside. This structure of the first closure member 45 is simple and easy to manufacture. Alternatively, the bottom end of the storage bin outlet 25 is open, and the first closure member 45 includes a connecting blocking portion and a protruding portion, with the blocking portion extending into the storage bin outlet 25. Specifically, the blocking portion extends from the bottom end of the storage bin outlet 25 into the storage bin outlet 25.The protruding portion projects beyond the storage bin sidewall 46 toward the feeding bin 26, allowing for abutment with the first pusher 48. The first closure member 45 can seal the storage bin outlet 25 within the storage bin outlet 25. The height, position, and configuration of the protruding portion can be adjusted as needed, allowing for considerable design flexibility. As shown in Figure 11, the feeding bin 26 has a first feeding bin sidewall 49 facing the storage bin 24. The first feeding bin sidewall 49 can be parallel to the storage bin sidewall 46. The first pusher 48 extends from the first feeding bin sidewall 49 and protrudes toward the storage bin 24. In other words, the first pusher 48 is a boss formed on the first feeding bin sidewall 49. When the feeding bin 26 is between the first actuated position and the material receiving position, or between these two positions, the first closure member 45 is positioned between the first feeding bin sidewall 49 and the storage bin sidewall 46. The first pusher 48 is positioned above the first closure member 45 and abuts against its upper surface. The protruding first push portion 48 can extend horizontally to the location of the first closure member 45. The feed bin 26 has a simple structure, making it easy to manufacture. The first push portion 48 is located at the top of the feed bin 26, so that the feed bin inlet 27 is located at the first push portion 48. In one example, the feed bin inlet 27 can be located on the side wall of the first push portion 48, facing the storage bin 24. Alternatively, the feed bin inlet 27 can be located on the upper wall of the first push portion 48, facing upward. This arrangement brings the feed bin inlet 27 closer to the storage bin outlet 25, forming a material receiving passage between the two and preventing material leakage. In this embodiment, a gap exists between the sidewall of the first pusher 48 and the storage bin sidewall 46 to prevent the feed bin 26 from getting stuck during movement. At the same time, the gap should be small enough to prevent material from leaking out. Optionally, the gap ranges from 0.1 mm to 1.5 mm, preferably from 0.2 mm to 1 mm. As described above, a feed bin outlet 28 is defined at the bottom of the feed bin 26. Furthermore, the feed bin outlet 28 faces away from the storage bin 24. The feed bin 26 has material intake on one side and discharge on the other. When in the material receiving position, the feed bin 26 is located at the bottom of the material box 22, and the storage bin outlet 25 is higher than the inner bottom surface of the feed bin 26. This allows material to be fed into the feed bin 26 by gravity.To automatically reset the first closure member 45, as shown in Figure 12, a first biasing member 47 is further provided within the material bin 22. The first biasing member 47 is located below the material storage bin 24 and connected to the first closure member 45. Specifically, the first closure member 45 has a mounting portion 51, and a first mounting seat 52 is provided at the bottom of the material bin 22. The first biasing member 47 has two ends connected to the mounting portion 51 and the first mounting seat 52, respectively. The first biasing member 47 can be configured to provide a biasing force to the first closure member 45, thereby maintaining the first closure member 45 in the closed position. When the first closure member 45 is arranged vertically, the first biasing member 47 is also arranged vertically and provides an upward biasing force to the first closure member 45. In this case, the mounting portion 51 protrudes horizontally. Optionally, the first biasing member 47 is a retractable member such as a spring that provides an elastic force. With the help of the first biasing member 47, as the feeding hopper 26 completes receiving material and ascends, the biasing force exerted by the first biasing member 47 gradually drives the first sealing member 45 to the closed position. As the feeding hopper 26 ascends, the first sealing member 45 gradually blocks the storage hopper outlet 25, preventing material leakage. Furthermore, the first biasing member 47 maintains the first sealing member 45 in the closed position, keeping the storage hopper outlet 25 in a normally closed state. As described above, the feeding hopper 26 can be driven by the screw drive mechanism 30. As shown in Figures 11 and 13, the feeding hopper 26 is provided with a screw hole 50. Optionally, the screw hole 50 is located near the feeding hopper inlet 27 and away from the feeding hopper outlet 28. The screw 31 passes through the screw hole 50. oThe feed bin 26 has a maximum unidirectional stroke on the screw 31. The initial position of the feed bin 26 is located in the middle of the maximum unidirectional stroke (see Figure 3) or at the upper end, away from the feeding position. The transmission structure between the screw drive 32 and the screw 31 can be a gear 53, as shown in Figure 12. For example, the screw 31 is fitted with a gear 53, and the end of the screw drive 32 is fitted with another gear 53, with the two gears 53 meshing with each other. The position of the storage bin outlet 25 is away from the position corresponding to the screw 31. Two storage bin outlets 25 are shown as an example. Correspondingly, as shown in Figure 11, the feed bin inlet 27 corresponds to each of the storage bin outlets 25, with the screw 31 positioned between the two feed bin inlets 27. Optionally, the shape of the feed bin inlet 27 corresponds to the shape of the storage bin outlet 25. The caliber of the feed hopper inlet 27 is larger than that of the storage hopper outlet 25. Thus, when the feed hopper inlet 27 and the storage hopper outlet 25 are docked, material flows out of the small opening and into the larger opening unimpeded, resulting in smoother material discharge and higher efficiency. The storage hopper outlet 25 includes straight and / or curved edges, or has rounded edges. The storage hopper outlet 25 can be polygonal, such as a rectangle, a circular shape with curved edges, or a circle. The length L11 of the straight edge is greater than 5 mm, the length L12 of the curved edge is greater than 5 mm, and the diameter D1 of the circular edge is greater than 5 mm. L12, L12, and D1 can be suitable values ​​such as 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. The area S1 of the storage hopper outlet 25 is greater than 25 mm², and S1 can be suitable values ​​such as 25 mm², 28 mm², 30 mm², 32 mm², or 35 mm². It should be noted that these dimensions apply to a single storage bin outlet 25. As shown in Figures 14 and 15 , the material bin 22 further includes a lifting channel 54 within the material bin housing 29. The screw 31 and the feed bin 26 are both located within the lifting channel 54, where the feed bin 26 is raised and lowered. The sidewalls of the lifting channel 54 that form the storage bin 24 are the storage bin sidewalls 46. The provision of the lifting channel 54 allows the storage bin 24 to be separated without affecting the raising and lowering of the feed bin 26. It also facilitates the installation of the feed bin 26 and its drive mechanism within the lifting channel 54.The feed bin 26 rises and falls along a vertically extending straight line, resulting in the lifting channel 54 being a vertically extending straight channel. One of the lifting channel 54 and the feed bin 26 is provided with a rib 55, while the other is provided with a groove 56, within which the rib 55 slides relative to the other. Figure 14 shows the lifting channel 54 with the rib 55, which is arranged vertically; correspondingly, the feed bin 26 is provided with the groove 56, which is also arranged vertically. For example, the rib 55 is provided on both front-to-back side walls of the lifting channel 54, and the groove 56 is provided on both front-to-back side walls of the feed bin 26. Thanks to the restraining effect of the rib 55 and the groove 56, the feed bin 26 remains stationary when the screw 31 rotates, allowing for lifting and lowering motion. This restraining structure is simple, facilitating the manufacture of the material bin 22. Figure 14 also illustrates the horizontal positions of the first biasing member 47 and the screw 31. In the illustrated cross-section, the first biasing member 47 is located in the horizontal middle of the first closure member 45, roughly corresponding to the position of the screw 31. The sidewall 49 of the first feeding bin forms a recessed portion for accommodating the screw 31. The lifting channel 54 is also provided with vertical slots 57, with both ends of the first closure member 45 positioned within corresponding vertical slots 57. The first closure member 45 is horizontally restrained within the vertical slots 57 to prevent horizontal movement. During movement, the vertical slots 57 provide guidance, ensuring that the first closure member 45 remains vertically aligned and prevents deflection. Furthermore, as described above, the bin discharge section 33 includes a discharge channel 80, and the washing bin 13 serves as a washing container. Specifically, as shown in Figures 16 and 17, the bin discharge section 33 includes a channel inlet 81, a channel outlet 82, and a discharge channel 80 extending between the channel inlet 81 and the channel outlet 82. The channel inlet 81 is higher than the channel outlet 82, and the discharge channel 80 is tilted to allow materials to be discharged automatically under the action of their own gravity. When the feed hopper 26 is in the receiving position, it communicates with the storage hopper outlet 25, specifically, the feed hopper inlet 27 and the storage hopper outlet 25. When the feed hopper 26 is in the feeding position, it communicates with the discharge channel 80 via the channel inlet 81, specifically, the feed hopper outlet 28 and the discharge channel 80. In the feeding position, the feed hopper 26 is located at the top of the material box 22, and the inner bottom surface of the feed hopper 26 is higher than the inner bottom surface of the discharge channel 80.Thus, materials can be fed into the material bin discharge section 33 by gravity. With this arrangement, materials within the storage bin are first transported by the feed bin 26 and then fed to the material washing container outside the bin 22 via the discharge channel 80. This increases the distance between the feed bin 26 and the material washing container, freeing the feed bin 26 from being positioned within the cooking appliance, thereby increasing product design flexibility. Furthermore, the feed bin 26 utilizes a lifting mechanism for transport, simplifying the transport structure and reducing manufacturing costs. As shown in Figures 16 and 17 , the bottom of the feed bin 26 is also provided with a second closure member 61 that closes the feed bin outlet 28. The second closure member 61 is movable between a closed position, blocking the feed bin outlet 28, and an open position, opening the feed bin outlet 28. The main portion of the second closure member 61 is plate-shaped, and therefore can also be referred to as a baffle. By opening the second closure member 61, the feed bin 26 can communicate with the feed bin outlet 28 when in the feeding position. In different embodiments, the second sealing member 61 exists in different states when the feeding bin 26 is in the feeding position. In one embodiment, the second sealing member 61 is always in the open state when the feeding bin 26 is in the feeding position. In another embodiment, the second sealing member 61 is initially in the closed state and then moved to the open state when the feeding bin 26 is in the feeding position. Specifically, when the feeding bin 26 is in the feeding position, there is a period of time during which the second sealing member 61 is in the open state, allowing the feeding bin 26 to communicate with the feeding bin outlet 28. This period of time can be the entire time the feeding bin 26 is in the feeding position, or it can be a portion of the time. Specifically, in one example, the second sealing member 61 is simultaneously opened during the process of the feeding bin 26 moving to the feeding position, allowing the feeding bin 26 to communicate directly with the feeding bin outlet 28. In another example, the second sealing member 61 is not opened when the feeding bin 26 just moves to the feeding position or for a period of time. The second sealing member 61 is opened after the feeding bin 26 remains in the feeding position for a period of time, allowing the feeding bin 26 to communicate with the feeding bin outlet 28. Regarding the opening method of the second sealing member 61, as shown in the illustrated embodiment, the feeding bin 26 can push the second sealing member 61 open, thereby utilizing the movement of the feeding bin 26 to open the feeding bin outlet 28.Alternatively, a separate actuator can be provided to push the second closure member 61 open. The following describes this in detail using the illustrated embodiment as an example. In this embodiment, when the feeding hopper 26 rises, the hopper discharge portion 33 can push the second closure member 61 from the closed position to the open position. Specifically, the hopper discharge portion 33 includes a second pusher 63. In other words, the second pusher 63 is formed on the hopper discharge portion 33. The feeding hopper 26 has a second trigger position located between the receiving position and the feeding position. Specifically, the second trigger position is located below and proximate to the feeding position. Figure 16 shows the feeding hopper 26 in the second trigger position. When the feeding hopper 26 is in the second trigger position, the second pusher 63 engages the second closure member 61 in the closed position. When the feeding hopper 26 rises from the second trigger position to the feeding position, the second pusher 63 pushes the second closure member 61 from the closed position to the open position, thereby opening the feeding hopper outlet 28. When the second closure member 61 is in the open position, the second pusher 63 remains in contact with the second closure member 61, preventing it from resetting. In this embodiment, the second closure member 61 can be driven to open the feed bin outlet 28 by controlling the movement of the feed bin 26. During feeding, the second closure member 61 remains in the open position, thereby facilitating automatic feeding. After feeding is completed, the feed bin 26 descends. At this point, the second pusher 63 no longer abuts the second closure member 61, and the material bin discharge portion 33 no longer provides thrust to the second closure member 61, allowing the second closure member 61 to reposition. This eliminates the need for an electric drive device to move the second closure member 61, saving manufacturing and operating costs. It also reduces the number of components in the cooking appliance 1, simplifies the product structure, conserves installation space, and facilitates product miniaturization. The feeding bin 26 may have a second feeding bin sidewall 64 extending vertically. The feeding bin outlet 28 is arranged vertically and faces the side where the second push portion 63 is located. The second closing member 61 is movable vertically, and a major portion of the second closing member 61 may be parallel to the second feeding bin sidewall 64. The open position of the second closing member 61 is located below its closed position.With this arrangement, the second closure member 61 can move in the opposite direction of the feed bin 26, allowing them to move synchronously but in opposite directions. This makes opening the second closure member 61 easier and simplifies the arrangement. The feed bin 26 may have a feed bin side surface 74 facing the bin discharge portion 33, with the feed bin outlet 28 formed on the feed bin side surface 74. In the illustrated embodiment, the second closure member 61 is entirely located outside the feed bin outlet 28 on the side facing the feed bin and abuts against the feed bin side surface 74. The second closure member 61 can block the feed bin outlet 28 from outside the feed bin outlet 28. The second closure member 61 has a simple structure, such as a plate-shaped structure, which facilitates manufacturing. Alternatively, the bottom end of the feed bin outlet 28 is open, and the second closure member 61 includes a connected blocking portion and a protruding portion. In the closed position, the blocking portion can extend into the feed bin outlet 28. The protruding portion projects beyond the feed bin side 74 toward the feed bin 26 so as to abut against the second pusher 63. This allows the blocking portion of the second closure member 61 to block the feed bin outlet 28 within the feed bin outlet 28. The height, position, and configuration of the protruding portion can be adjusted as needed, providing considerable design flexibility. The feed bin inlet 27 can face the feed bin 26. Alternatively, the feed bin inlet 27 can face upward. As shown in Figures 18 and 19, the feed bin 26 includes a second feed bin sidewall 64 that faces away from the feed bin inlet 27. The second feed bin sidewall 64 extends vertically. The feed bin outlet 28 is located on the second feed bin sidewall 64, so that the feed bin inlet 27 faces away from the second pusher 63, or the bin discharge portion 33, while the feed bin outlet 28 faces the second pusher 63, or the bin discharge portion 33. Alternatively, the feed bin outlet 28 can face downward. The feed bin 26 can have one side for feeding and the other side for discharging, or one side for feeding and the other side for discharging. Optionally, the top of the feed bin 26 is open and covered with a feed bin cover 66, which is detachably connected to the feed bin 26. As shown in Figure 19, the second closure member 61 can have an upwardly facing recess 67 for receiving the second pusher 63. The second pusher 63 can abut against the bottom wall of the recess 67 to push the second closure member 61 to move.Specifically, when the feeding bin 26 is in the second trigger position and the feeding position, the second pusher 63 is located within the recess 67. As the feeding bin 26 moves between these two positions, a guided sliding motion occurs between the second pusher 63 and the vertical wall of the recess 67. The provision of the recess 67 limits the position of the second pusher 63 relative to the feeding bin 26 and provides guidance for the movement of the second closing member 61, ensuring that the second pusher 63 smoothly pushes the second closing member 61. The feeding bin 26 may be provided with a vertically extending chute 68, with a sliding member 69 connected to the second closing member 61. The sliding member 69 is at least partially located within the chute 68 and between its two vertically extending walls, and moves up and down along the chute 68. The feed bin 26 uses the chute 68 to restrict the position of the slider 69, allowing the second closure member 61 to connect to the feed bin 26. The chute 68 also guides the movement of the slider 69, ensuring smooth vertical movement of the second closure member 61 and horizontally restricting the relative position of the second closure member 61 to the feed bin 26. Optionally, the chute 68 is located above the feed bin outlet 28, while the slider 69 is located above and connected to the top of the second closure member 61. This arrangement allows the slider 69 to occupy the space above the feed bin outlet 28, avoiding occupying the feeding channel there and affecting the material discharge flow rate. Furthermore, the vertical dimension of the feed bin 26 is relatively small, facilitating its miniaturization. For example, the top of the second closure member 61 may be provided with a mounting portion 70 that protrudes toward the center of the feed bin 26, and the end of the second closure member 61 may be fixed to the mounting portion 70. For example, the mounting portion 70 may be provided with a mounting hole 71, and the second closure member 61 may be inserted into the mounting hole 71. Of course, the fixing structure of the sliding member 69 is not limited and may also include fasteners such as screws or other suitable fixing structures. In a preferred example, as shown in the embodiment, the chute 68 is a horizontally extending through-slot. The feed bin 26 is provided with a side boss 72 that protrudes from the second feed bin sidewall 64, and the chute 68 extends horizontally through the side boss 72. Specifically, the feed bin 26 has a first horizontal direction and a second horizontal direction. The second feed bin sidewall 64 extends in the first direction, and the side boss 72 protrudes in the second direction.The side boss 72 has a boss end surface 73 in the first direction and a feed bin side surface 74 in the second direction, facing the side where the second pusher 63 is located. The chute 68 extends through the boss end surfaces 73 at both ends. In the illustrated embodiment, the first direction is the front-to-back direction, and the second direction is the left-to-right direction. The feed bin outlet 28 is formed on the side boss 72, specifically, on the feed bin side surface 74 of the side boss 72. Optionally, the shape of the feed bin outlet 28 corresponds to the shape of the channel inlet 81. The diameter of the feed bin outlet 28 is smaller than that of the channel inlet 81. As a result, when the feed bin outlet 28 and the channel inlet 81 are aligned, material flows out of the small opening and into the large opening unimpeded, resulting in smoother material discharge and higher efficiency. The feed bin outlet 28 may include straight and / or curved edges, or may have rounded edges. The feed bin outlet 28 may be polygonal, such as a rectangle, a circular indentation with curved edges, or a circle. The length of the straight side, L21, is 2.5 mm; the length of the curved side, L22, is 2.5 mm; the diameter of the circular side, D2, is 2.5 mm. L21, L22, and D2 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or other suitable values. The area S2 of the feed bin outlet 28 is greater than 25 mm²; S2 can be 25 mm², 28 mm², 30 mm², 32 mm², 35 mm², or other suitable values. It should be noted that these dimensions apply to a single feed bin outlet 28. The sliding member 69 is disposed within the chute 68 and connected to the second closure member 61 at both ends. With the help of the side boss 72, the slide groove 68 can be easily set to facilitate the fixation of the second closing member 61; and the feeding bin outlet 28 can be closer to the second pushing portion 63 relative to the second feeding bin side wall 64, so that the second closing member 61 located outside the feeding bin outlet 28 can easily touch the second pushing portion 63, facilitating the opening of the second closing member 61.In other examples (not shown), the slide groove 68 may have a closed inner end in the horizontal direction, rather than being a through groove. The side boss 72 may be provided with a slide groove 68 on each boss end surface 73 in the first direction. A sliding member 69 is provided at one end of the side boss 72 and extends through the corresponding slide groove 68, while another sliding member 69 extends through the corresponding slide groove 68 at the other end of the side boss 72. The second closure member 61 is connected to two fixed walls 75. The mounting portion 70 is located above and connected to the corresponding fixed walls 75. The fixed walls 75 may be plate-shaped. The side boss 72 is located between the two fixed walls 75 and is positionally connected to each fixed wall 75 via a concave-convex structure. Specifically, one of the side boss 72 and the fixed wall 75 is provided with a protruding retaining rib 76, while the other is provided with a recessed retaining groove 77. The retaining rib 76 is located within the retaining groove 77, and relative sliding occurs between the two when the second closure member 61 moves. The side bosses 72 effectively restrict the horizontal movement of the second closure member 61. Specifically, they restrict horizontal movement of the second closure member 61 in a direction generally parallel to the second feeding hopper sidewall 64, as well as horizontal movement away from the second feeding hopper sidewall 64 (or perpendicular to the second feeding hopper sidewall 64). This allows the second closure member 61 to remain in both the closed and open positions, and to smoothly open and close the second closure member 61. For example, a limiting rib 76 is provided on the side boss 72, specifically protruding from the boss end surface 73. A limiting groove 77 is provided on the fixed wall 75. OTo automatically reset the second closure member 61, as shown in Figures 19 and 20, a second biasing member 62 is further provided within the feed bin 22 and located within the feed hopper 26. Exemplarily, the second biasing member 62 is located within a chute 68. Specifically, a second mounting seat 65 is provided at the bottom of the chute 68. The second biasing member 62 is connected to the second mounting seat 65 and sandwiched between the second mounting seat 65 and the sliding member 69. The second biasing member 62 can be configured to provide a biasing force to the second closure member 61, thereby maintaining the second closure member 61 in the closed position. When the second closure member 61 is arranged vertically, the second biasing member 62 is also arranged vertically and provides an upward biasing force to the second closure member 61. Optionally, the second biasing member 62 is a retractable member such as a spring that provides an elastic force. With the help of the second biasing member 62, as the feeding hopper 26 completes feeding and descends, the biasing force exerted by the second biasing member 62 drives the second sealing member 61 to gradually move to the closed position. As the feeding hopper 26 descends, the second sealing member 61 gradually blocks the feeding hopper outlet 28, preventing material leakage. Furthermore, the second biasing member 62 maintains the second sealing member 61 in the closed position, keeping the feeding hopper outlet 28 in a normally closed state. As described above, the feeding hopper 26 is driven by the screw drive mechanism 30. As shown in FIG18 , the feeding hopper 26 is provided with a screw hole 50. Optionally, the screw hole 50 is located near the feeding hopper inlet 27 and away from the feeding hopper outlet 28. The screw 31 passes through the screw hole 50. The feeding hopper 26 has a maximum unidirectional travel on the screw 31. The initial position of the feeding hopper 26 is located in the middle (see FIG3 ) or at the upper end of the maximum unidirectional travel, away from the feeding position. As described above, the hopper discharge portion 33 moves between an initial position and a discharge position. In the discharge position, the hopper discharge portion 33 can communicate with the feed bin 26. Specifically, when the feed bin 26 is in the feeding position and the hopper discharge portion 33 is in the discharge position, the hopper discharge portion 33 communicates with the feed bin 26. As shown in FIG21 , the feed bin 26 has a push position located between the receiving position and the feeding position. When the feed bin 26 rises from the push position to the feeding position, the feed bin 26 pushes the hopper discharge portion 33 from the initial position to the discharge position.Thus, the feed bin 26 can be controlled to move the material bin discharge portion 33 to the discharge position. During feeding, the material bin discharge portion 33 remains in the discharge position, facilitating automatic feeding. After feeding is completed, the feed bin 26 descends below the push position. At this point, the feed bin 26 no longer provides thrust to the material bin discharge portion 33, allowing it to return to its original position. This eliminates the need for an electric drive device to drive the material bin discharge portion 33, saving manufacturing and operating costs, reducing the number of components in the cooking appliance, and simplifying the product structure. Compared to the feed bin 26 in the second trigger position shown in FIG16 , the push position is located below this second trigger position. The height of the feed bin 26 in the push position is lower than its height in the second trigger position. During its ascent, the feed bin 26 first rises to the push position, then to the second trigger position, and finally to the feed position. As the feeding bin 26 rises, it first pushes the bin discharge portion 33 to the discharge position, and then the bin discharge portion 33 pushes the second closure member 61 to open the feeding bin outlet 28. As shown in Figures 18, 19, and 20, the feeding bin 26 has a pushing surface 78 for contacting the bin discharge portion 33. The pushing surface 78 is inclined downward from top to bottom toward the bin discharge portion 33. The horizontal dimension of the pushing surface 78 is greater than the travel distance of the bin discharge portion 33. The inclined pushing surface 78 provides guidance for the bin discharge portion 33, ensuring smooth movement. The bin discharge portion 33 has an angled end that can contact the pushing surface 78, either in a linear or planar manner. The pushing surface 78 and the feeding bin side surface 74 are formed on the side boss 72, with the pushing surface 78 located at the top of the side boss 72. The side bosses 72 facilitate the placement of the push surface 78 while avoiding occupying space within the feed bin 26. The push surface 78 is located above the feed bin outlet 28. Specifically, the push surface 78 is located above and connected to the feed bin side surface 74. In other words, the feed bin side surface 74 extends downward from the bottom of the push surface 78. The feed bin side surface 74 is parallel to the end surface of the bin discharge portion 33 that forms the channel entrance 81. During the opening of the feed bin outlet 28, the end surface of the bin discharge portion 33 that forms the channel entrance 81 maintains close contact with the feed bin side surface 74.Illustratively, the feed bin side surface 74 is arranged vertically, and the channel inlet 81 (or the end surface where the channel inlet 81 is located) is also arranged vertically. The dimension between the bottom end of the pushing surface 78 and the top end of the feed bin outlet 28 is greater than the dimension between the top and bottom ends of the channel inlet 81. This arrangement ensures that during the opening of the feed bin outlet 28, the end surface of the bin discharge portion 33 forming the channel inlet 81 maintains close contact with the feed bin side surface 74, ensuring seamless connection between the feed bin outlet 28 and the channel inlet 81 and preventing material leakage. As shown in Figures 22 and 23, a third biasing member 83 is also provided within the feed bin 22 and located at the bin discharge portion 33. The third biasing member 83 is configured to provide a biasing force to the bin discharge portion 33 to maintain it in its initial position. When the bin discharge portion 33 moves horizontally, a third biasing member 83 is arranged horizontally and provides a horizontal biasing force for the bin discharge portion 33. Optionally, the third biasing member 83 is a retractable member such as a spring that provides an elastic force. With the help of the third biasing member 83, as the feeding hopper 26 completes feeding and descends, the biasing force exerted by the third biasing member 83 drives the bin discharge portion 33 to gradually move to its initial position (i.e., reset) and maintain it there. Furthermore, during the movement of the bin discharge portion 33, the biasing force ensures that the end surface of the bin discharge portion 33, which forms the channel entrance 81, maintains close contact with the feeding hopper side 74, ensuring seamless connection between the feeding hopper outlet 28 and the channel entrance 81 and preventing material leakage. The lifting channel 54 has multiple sidewalls, one of which is used to accommodate the bin discharge portion 33 and is therefore referred to herein as the supporting sidewall 84. The supporting sidewall 84 is provided with a channel-side opening 85, into which the material box discharge portion 33 is disposed, and their shapes are compatible. The lifting channel 54 is provided with a fixed seat 87 with a limiting wall 86, which is used to support the material box discharge portion 33 upward and limit its position. The fixed seat 87 is connected to the supporting sidewall 84 of the lifting channel 54. The supporting sidewall 84 is arranged vertically, and the limiting wall 86 is also arranged vertically. The material box discharge portion 33 is connected to a protruding arm 88, which can be positioned between the limiting wall 86 and the supporting sidewall 84 of the lifting channel 54.This limits the travel of the discharge section 33. The position of the limiting wall 86 defines the initial position of the discharge section 33, where it abuts the limiting wall 86. Furthermore, the protruding arm 88 defines a guide hole 89, and the supporting sidewall 84 of the lifting channel 54 is provided with a guide post 90 that can be inserted into the guide hole 89. This arrangement limits the position of the discharge section 33 relative to the lifting channel 54, specifically in the front-to-back and vertical directions, and provides guidance for the discharge section 33, ensuring smooth movement. When the discharge section 33 moves, the guide hole 89 allows it to move along the guide post 90. Schematically, the protruding arm 88 is provided on either side of the discharge section 33 in the horizontal direction, for example, in the front-to-back direction. Fixed seats 87 are spaced apart in the lifting channel 54 and located on either side of the channel-side opening 85 in the horizontal direction, corresponding to the position of the protruding arms 88. Each protruding arm 88 is provided with a guide hole 89, and guide posts 90 are located on either side of the channel-side opening 85 in the horizontal direction, corresponding to the position of the guide holes 89. The third biasing member 83 can be sandwiched between the protruding arm 88 and the supporting side wall 84. Specifically, the protruding arm 88 is provided with a third mounting seat 91, and the third biasing member 83 is connected to the third mounting seat 91 and sandwiched between the third mounting seat 91 and the supporting side wall 84. In the illustrated embodiment, the third mounting seat 91 also has a guide hole 89, and the third biasing member 83 is mounted on the guide post 90. The material box housing 29 is provided with a material box side opening 92, which corresponds to the position of the channel-side opening 85. The material box discharge portion 33 is disposed within the material box side opening 92. Specifically, the material box discharge portion 33 is located within the material box housing 29 in the initial position and extends through the material box side opening 92 in the discharge position. The material box side opening 92 faces the pot lid 5 horizontally and covers the material box side opening 92 when the pot lid 5 is closed. The material box side opening 92 is covered and hidden by the pot lid 5 in the closed position, simplifying the external structure of the cooking appliance and improving its overall appearance.This arrangement facilitates the delivery of material to the material washing container. In the illustrated embodiment, the material washing container is located within the pot lid 5. The extended material bin discharge portion 33 allows it to extend through the feed inlet 7 into the pot lid 5, facilitating communication. Material is then delivered to the material washing container (i.e., the material washing bin) via the feeding device 34. The side opening 92 of the material bin aligns with the outer contour of the material bin discharge portion 33. For example, if the side opening 92 is rectangular, the outer contour of the material bin discharge portion 33 is also rectangular in cross-section. Referring to Figure 15, the material bin 22 includes a position detection device 58 for detecting the position of the feed bin 26, the position of the first closure member 45 / second closure member 61, the position of the material bin discharge portion 33, and / or the number of revolutions of the screw 31. As shown in Figure 19 , for example, a position detection device 58 can be located at the docking position between the feed bin 26 and the bin discharge portion 33. This device can detect whether the feed bin 26 is in the feeding position. Upon detecting that the feed bin 26 is in the feeding position, the device can confirm that the feed bin 26 is docked with the bin discharge portion 33, at which point the screw drive device 32 is deactivated. The position detection device 58 can be a microswitch, a Hall effect element, or an optical coupler sensor. The bin 22 also includes a bin base 59, which is connected to the wall of the lifting channel 54. A portion of the bin base 59 forms the bottom wall of the storage bin 24. The bin base 59 is located within the bin housing 29, and the first biasing member 47, the screw drive device 32, and other components are located within the base 59. The top of the lifting channel 54 is open and covered by a channel cover 60, which is removably connected to the top of the lifting channel 54. The bin discharge portion 33 is capable of docking with the feed inlet 7 of the pot lid 5. Specifically, the material box discharge portion 33 is misaligned with the feed port 7 when the pot cover 5 is opened (see Figure 2), and the material box discharge portion 33 can be moved to the discharge position to dock with the feed port 7 when the pot cover 5 is closed (see Figures 16 and 17).It should be noted that the “misalignment” here includes a positional relationship in which the material box discharge portion 33 and the feed port 7 cannot form a material conveying passage by moving the material box discharge portion 33. For example, when the pot lid 5 is opened, the material box discharge portion 33 is spaced apart from the feed port 7 in the horizontal direction and / or vertical direction; the “docking” here includes a positional relationship in which a material conveying passage can be formed between the material box discharge portion 33 and the feed port 7. For example, a portion of the material box discharge portion 33 extends into the feed port 7. Alternatively, the material box discharge portion 33 is on the upper side of the feed port 7 and overlaps in the horizontal direction. The material in the material bin 22 can be fed to the pot lid 5 through a movable material bin discharge portion 33. When the pot lid 5 is closed, the material bin discharge portion 33 forms a material feeding passageway with the feed inlet 7. When the pot lid 5 is open, no material feeding passageway is formed, allowing material feeding to occur only when the pot lid 5 is closed. This enables automatic rice feeding, improving the user experience and the level of product automation. The material bin 22 is located horizontally to one side of the pot lid 5. The position of the material bin 22 can be adjusted without considering the space required for opening and closing the pot lid 5, allowing for greater design freedom. The material bin discharge portion 33 moves linearly in the horizontal direction, for example, in the left-right direction. This facilitates docking of the material bin discharge portion 33 with the feed inlet 7 of the pot lid 5, minimizing the space occupied by movement. In its initial position, the material bin discharge portion 33 is concealed within the outer shell of the material bin 22. In the discharge position, the material bin discharge portion 33 is at least partially concealed within the pot lid 5. In this way, the material box discharge portion 33 is concealed within the cooking appliance, simplifying the external structure and improving the overall appearance of the cooking appliance, enhancing the product's visual appeal. Furthermore, in its initial position, the material box discharge portion 33 is concealed within the material box 22 without interfering with the opening of the pot lid 5. In the discharge position, it is at least partially concealed within the pot lid 5, facilitating the formation of a material delivery channel with the feed inlet 7. The discharge inlet 23 is lower than the top wall of the pot lid 5 when closed, ensuring that at least the portion of the material box discharge portion 33 that interfaces with the pot lid 5 is covered and concealed by the pot lid 5. The material box 22 is higher than the pot lid 5, allowing the entrance of the material box discharge portion 33 to be located higher than the pot lid 5, allowing the material to flow automatically to the feed inlet 7 due to its own gravity.The feed inlet 7 is provided on the side wall of the lid 5 facing the material bin 22, allowing material to enter the lid 5 from the side of the lid 5. Alternatively, the feed inlet 7 can be provided on the top wall of the lid 5, allowing material to enter the lid 5 from the top side of the lid 5. When in the discharge position, the material bin discharge portion 33 is partially located within the lid 5 and partially located in the gap between the material bin 22 and the lid 5, below the top surface of the lid 5. During operation, the extended portion of the material bin discharge portion 33 is shielded and concealed by the lid 5. The remaining portion of the material bin discharge portion 33 in the discharge position is located within the outer shell of the material bin 22. When in operation, the material bin discharge portion 33 is shielded by the outer shell of the material bin 22 and the lid 5, remaining substantially entirely concealed within the cooking appliance. This simplifies the external structure of the cooking appliance, improves its overall appearance, and enhances the product's visual appeal. Furthermore, the pot lid 5 or the material bin 22 is equipped with a position detection device for detecting the position of the material bin discharge portion 33 and / or the position of the pot lid 5. Based on the detected position signal of the pot lid 5, the device can determine whether the pot lid 5 is closed, thereby controlling the movement of the material bin discharge portion 33 when the pot lid 5 is closed. Based on the detected position signal of the material bin discharge portion 33, the device can determine whether the material bin discharge portion 33 is located at the discharge position. When the material bin discharge portion 33 is located at the discharge position, docking is confirmed, and the outlet of the feed bin 26 can be opened for material delivery. The control unit is configured to control the movement of the material bin discharge portion 33 based on the position signal detected by the position detection device when the pot lid 5 is closed. In the illustrated embodiment, the control unit controls the movement of the feed bin 26 by controlling the screw drive device 32, thereby controlling the movement of the material bin discharge portion 33. Before the cooking appliance performs the feeding step, it first ensures that the pot lid 5 is securely closed, and then moves the material bin discharge portion 33 to align with the material inlet 7. Furthermore, as described above, the pot lid 5 is equipped with a feeding device 34, a feeding drive 100, and a material washing bin 13 serving as a receiving container. Figures 24 to 30 further illustrate the structure of the pot lid 5, wherein the material washing bin 13 is detachable from the pot lid 5, and the feeding device 34 is also detachable from the pot lid 5. The following description uses the material washing bin 13 as an example of a receiving container. As shown in Figure 24, the material washing bin 13 and the removable lid 9 are constructed as a single unit and are removably attached to the pot lid body 8.The washing bin 13 and the removable lid 9 can be removed from the pot lid 5 or assembled together, reducing assembly and disassembly steps, improving efficiency, and enhancing the user experience. The washing bin 13 and the removable lid 9 can be removed and cleaned together at any time, preventing residual materials from becoming moldy or infested with insects over time. Optionally, the pot lid 5 is equipped with a position detection device for detecting the position of the washing bin 13 or the removable lid 9. The detected position detection signal of the washing bin 13 or the removable lid 9 can be used to determine whether the washing bin 13 and the removable lid 9 are properly installed, preventing the cooking appliance from operating if the washing bin 13 and the removable lid 9 are not installed. In the embodiment (not shown) where the washing bin 13 and the removable lid 9 are separately installed, the washing bin 13 is separately removable, and a separate position detection device is provided for the washing bin 13, and a separate position detection device is provided for the removable lid 9. Furthermore, a sewage pipe 41 is provided on the removable cover 9, allowing it to be removed from the pot lid 5 along with the removable cover 9, facilitating cleaning of the interior of the sewage pipe 41. In the illustrated embodiment, the sewage pipe 41, the washing bin 13, and the removable cover 9 are integrally constructed. When the user wishes to clean these components, they can be removed in one go, simplifying the disassembly process and enhancing the user experience. In other alternatives (not shown), the sewage pipe 41 may be omitted. Instead, a water pipe may be directly inserted into the washing bin 13 to pump wastewater and discharge it from the washing bin 13. In this embodiment, the washing bin 13 may not have a sewage outlet. Returning to FIG8 , the pot lid body 8 may be provided with a recessed platform 96 and a receiving cavity 97 recessed upward from the recessed platform 96. The removable cover 9 may be located within the recessed platform 96. The material washing bin 13 is located within the receiving cavity 97, which is located in the middle of the pot lid 8. Consequently, the material washing bin 13 is located in the middle of the pot lid 5. Alternatively, the pot lid 8 may not have the recess 96, and the removable cover 9 may be located below the pot lid 8. The pot lid 5 has a feed inlet 7; the feed device 34 includes a movable feed assembly 36 for feeding material to a receiving container; and a feed drive 100 is used to drive the feed assembly 36. In one example, the feed drive 100 is fixedly mounted on the pot lid 8 and detachably connected to the feed device 34.As shown in FIG. 25 , the pot cover body 8 is further provided with a mounting opening 101 , and the feeding device 34 is detachably mounted to the pot cover body 8 via the mounting opening 101 , so that the feeding device 34 can be disassembled and assembled from the mounting opening 101 . OThe feeder 34 has no live components and is removable from the lid 5. When the feeder 34 is removed, the live feed drive device 100 remains attached to the lid body 8. This allows the feeder 34 to be removed and cleaned separately. Since the feeder 34 has no live components, it can be rinsed under a faucet or in a basin, eliminating the need for waterproofing and facilitating manufacturing. The feeder 34 can be removed and cleaned at any time, preventing residual materials from becoming moldy or infested with insects over time, thereby improving the user experience. Furthermore, the feeder 34 is concealed within the lid 5, maintaining a neat exterior and enhancing the product's appearance. Optionally, the lid 5 is equipped with a position detection device for detecting the position of the feeder 34. A detected position signal indicating the feeder 34 can be used to determine whether the feeder 34 is properly installed, preventing the cooking appliance from operating when the feeder 34 is missing. The aforementioned position detection device can detect whether relevant components are in place before the feed arrangement is executed. The control unit controls the docking of the material bin discharge section 33 based on various in-placement signals. These in-placement signals include signals indicating that the pot lid 5 is closed, that the removable lid 9 is installed, that the material washing bin 13 is installed, and that the feed device 34 is installed. Furthermore, the control unit controls the feeding of cooking utensils from the material bin discharge section 33 based on the docking in-placement signals of the feed device 33. In a preferred embodiment, as shown in Figure 25, the pot lid body 8 has a peripheral side wall 102 and an inner bottom wall 103. The peripheral side wall 102 extends vertically, while the inner bottom wall 103 extends horizontally. The mounting opening 101 is provided in the peripheral side wall 102, and the feed opening 7 is provided on the side surface of the feed device 34. The feeding device 34 can be disassembled and assembled from the circumferential side of the pot cover body 8 in the horizontal direction, and whether the feeding device 34 is installed on the pot cover 5 can be observed from the outside of the pot cover 5. In addition, as mentioned above, the detachable cover 9 is detachable from the lower side of the pot cover body 8, so that the disassembly order of the detachable cover 9 and the feeding device 34 is not affected. The feeding device 34 and the detachable cover 9 can be disassembled and cleaned separately, and the cleaning operation is more flexible.In this embodiment, the feed device 34 and the feed drive device 100 are supported on the inner bottom wall 103 (see Figures 26 and 27 ), and both are located above the inner bottom wall 103. This allows the feed device 34 and the feed drive device 100 to be concealed by the inner bottom wall 103. After the removable lid 9 is removed, the structure of the underside of the pot lid body 8 is neat and visually appealing. In another preferred embodiment (not shown), the feed inlet 7 is provided on the peripheral side wall 102, and the installation opening 101 is provided on the inner bottom wall 103. The feed device 34 can be vertically removed and assembled from the underside of the pot lid body 8, and the removable lid 9 is removable from the underside of the pot lid body 8. This eliminates the need to remove the removable lid 9 first, and then the feed device 34. This also avoids the need for a large installation opening 101 on the exterior of the pot lid 5, improving the appearance of the exterior of the pot lid 5. In this embodiment, the feed device 34 and the feed drive device 100 are supported on the inner bottom wall 103. The feed device 34 is located at the mounting opening 101, and the feed drive device 100 is located above the inner bottom wall 103. Therefore, after the removable cover 9 is removed, the feed device 34 is exposed from the inner bottom wall 103, while the feed drive device 100 is covered by the inner bottom wall 103. The feed device 34 is equipped with a rotatable first connector 104 (see FIG. 28 ), which is in driving connection with the feed assembly 36 to drive the feed assembly 36. The feed drive device 100 is equipped with a rotatable second connector 105 (see FIG. 27 ) that docks with the first connector 104, forming a driving connection between the two connectors. The second connector 105 drives the first connector 104 in rotation. The docking direction between the first connector 104 and the second connector 105 aligns with the assembly direction of the feed device 34. In the embodiment shown in FIG. 25 , the docking direction is horizontal, for example, left-right. For embodiments in which the mounting opening 101 is located on the inner bottom wall, the docking direction is upward. The feeder device 34 achieves quick connection with the feed drive device 100 during assembly and quick disconnection from the feed drive device 100 during disassembly, facilitating easy assembly and disassembly of the feeder device 34. In one example, the first connector 104 is connected to the second connector 105 via a plug-in structure, with the plug-in direction coinciding with the assembly direction of the feeder device 34.This solution utilizes a mechanical structure to connect the feed device 34 to the feed drive apparatus 100, resulting in high connection reliability, excellent anti-interference performance, and low manufacturing costs. Specifically, the second connector 105 may have an access port. As shown in Figure 27, the first connector 104 can be inserted into the access port of the second connector 105. The outer circumference of the first connector 104 is formed with first ribs 106 spaced apart along its circumference. The inner circumference of the access port is also formed with second ribs (not shown) spaced apart along its circumference. The first and second ribs 106 are interlaced, meaning that the first ribs 106 are located between adjacent second ribs. Alternatively, the access port may be provided on the first connector 104, and the second connector 105 can be inserted into the access port of the first connector 104. Another example is that the first connector 104 is connected to the second connector 105 via magnetic attraction. This solution utilizes magnetic force to connect the feed device 34 to the feed drive device 100, making the connection quick and easy, and the assembly process of the feed device 34 simple. Furthermore, the structure is simple, making it easy to manufacture. For example, the two connecting components may be entirely made of magnetic material, and at least one of the connecting components may be a magnet, such as a magnet. Alternatively, the two connecting components may have magnetic components embedded therein, and at least one of the magnetic components may be a magnet, such as a magnet. As shown in Figures 28 and 29, the feed device 34 also includes a device body 35 defining a receiving cavity. The device body 35 has a side port for feeding materials, through which materials enter the feed device 34. OThe feed assembly 36 is located within the accommodating cavity and below the end opening. Material entering through the end opening can fall onto the feed assembly 36 due to gravity, allowing it to be transported by the assembly 36 and preventing accumulation at the feed opening 7. In the embodiment shown in Figure 25 , where the mounting opening 101 is located on the peripheral side wall 102, the end opening serves as the feed opening 7; the end portion of the device body 35 is located within the mounting opening 101 and matches the mounting opening 101 in shape and size. In the embodiment where the mounting opening 101 is located on the inner bottom wall 103, the end opening is located inside the feed opening 7 and communicates with the feed opening 7. As described above, the material washing bin 13 is mounted within the pot lid body 8 and has a material inlet 18. The feed device 34 is located on one side of the material washing bin 13 in the horizontal direction, effectively utilizing the horizontal space of the pot lid 5 and reducing the height of the pot lid 5. The washing bin 13 can be located in the center of the lid 5 to facilitate the passage of washed material into the inner pot 4 and maintain the lid 5 stable during washing. The feed assembly 36 is located between the feed inlet 7 and the inlet 18. The feed assembly 36 comprises a belt drive assembly including a conveyor belt 37. Preferably, the feed inlet 7 is positioned at a height equal to or lower than the inlet 18. The conveyor belt 37 is arranged upwardly and tilted from the feed inlet 7 to the inlet 18, with an inclination angle a less than 50°. For example, a can be a suitable angle such as 50°, 45°, 40°, or 35°. The tilted conveyor belt 37 facilitates material transport from a low to high position, making it suitable for applications where the feed inlet 7 is located at a high position and preventing material accumulation at the feed inlet 7. The feed assembly 36 also includes a driving roller 107 and a driven roller 108 for housing the conveyor belt 37. The driving roller 107 is drivingly connected to the feed drive device 100 and corresponds to the location of the feed port 7. The driven roller 108 corresponds to the location of the feed port 18. Specifically, the driving roller 107 is located outside the driven roller 108, and its height is lower than that of the driven roller 108. The driving roller 107 is parallel to the driven roller 108, and both are rotatable about a horizontal axis of rotation.The feed drive device 100 is connected to the outer roller, and the output end of the feed drive device 100 can face outward. This facilitates positioning the feed drive device 100 along the assembly direction of the feed mechanism 34, allowing for quick connection and disconnection between the feed drive device 100 and the feed mechanism 34. The device body 35 is provided with a guide ramp 109 located below the feed inlet 7. The guide ramp 109 is located at the front end of the conveyor belt 37 in the conveying direction and horizontally overlaps the conveyor belt 37. Specifically, a portion of the guide ramp 109 extends directly above the front end of the conveyor belt 37, leaving a small gap between the guide ramp 109 and the conveyor belt 37. This gap is required to ensure normal movement of the conveyor belt 37 while preventing material from leaking through the gap. The guide slope 109 slopes downward from the feed port 7 to the inlet 18. Material entering from the feed port 7 slides along the guide slope 109 onto the conveyor belt 37, making material transportation easier and more efficient while effectively preventing accumulation and jamming of material at the front end of the conveyor belt 37. The device body 35 is also equipped with a scraper 110, located at the rear end of the conveyor belt 37 in the conveying direction. The scraper 110 is located below the upper surface of the conveyor belt 37. In other words, the scraper 110 is positioned below the upper surface of the conveyor belt 37 in the height direction. After the cooking appliance 1 is used, the scraper 110 can be used to remove material, dust, and other foreign matter remaining on the conveyor belt 37, effectively keeping the conveyor belt 37 clean. The scraper 110 is preferably made of a flexible material to prevent scratching the conveyor belt 37. The feed device 34 also includes a preload assembly 111 for adjusting the preload force of the conveyor belt 37. The pre-tensioning assembly 111 is located below the conveyor belt 37 and is movable in the vertical direction. By adjusting the height of the pre-tensioning assembly 111, the pre-tensioning force of the conveyor belt 37 can be adjusted to increase the friction between the rollers and the conveyor belt 37, thereby improving conveying efficiency. Specifically, as shown in Figure 30, the pre-tensioning assembly 111 includes a pre-tensioning shaft 112, a pre-tensioning mounting post 113, a pre-tensioning elastic member 114, and a pre-tensioning roller 115. The pre-tensioning roller 115 is mounted on both ends of the pre-tensioning shaft 112 and abuts against the conveyor belt 37. The pre-tensioning mounting post 113 is connected to the middle of the pre-tensioning shaft 112 and is movably connected to a first support 116 of the device body 35. The pre-tensioning elastic member 114 is used to provide an upward elastic force to the pre-tensioning shaft 112.Optionally, a preload elastic member 114 is sleeved over the preload mounting column 113 and sandwiched between the first support seat 116 and the preload shaft 112. Specifically, the device body 35 has two device sidewalls 117 forming a receiving chamber, and the conveyor belt 37 is located between the two device sidewalls 117. The driving roller 107 is rotatably supported by the two device sidewalls 117. A driven shaft 119 connected to the driven roller 108 is disposed across the two device sidewalls 117. The driven shaft 119 is fixedly supported by the two device sidewalls 117, and the driven roller 108 is rotatable about the driven shaft 119. The driving shaft 118 connected to the driving roller 107 is connected to the first connecting member 104 via a transmission gear 120. The device body 35 is provided with a second support base 121, on which the first connecting member 104 is rotatably supported. A transmission gear 120 is coaxially connected to the first connecting member 104, and another transmission gear 120 is sleeved on the driving shaft 118. The two transmission gears 120 mesh with each other. Optionally, there are two driven rollers 108, corresponding to two driven shafts 119. The two driven rollers are arranged side by side in a horizontal direction to form a horizontal upper surface at the rear end of the conveyor belt 37. Referring back to Figure 27, the material washing drive device 40 can be provided independently of the material feeding drive device 100 on the pot lid body 8. Two drive devices for washing and feeding are installed within the pot lid 5. The washing drive device 40 is located behind the feeding device 34, while the feeding drive device 100 is located in front of the feeding device 34. These two drive devices can be arranged in the space on either side of the feeding device 34, effectively utilizing the space within the pot lid 5. The transmission structure connecting each drive device is simple, facilitating manufacturing and assembly. Gear transmission is used to connect the output end of the washing drive device 40 to the driving unit 21. Figure 27 schematically illustrates three meshing gears: a first gear 122, a second gear 123, and a third gear 124. The first gear 122 is sleeved around the output end of the washing drive device 40, while the second gear 123 is located between the first and third gears 122 and 124. The third gear 124 is sleeved around the driving unit 21. In the illustrated embodiment, the top cover 19 of the washing bin 13 is equipped with a rotatable docking member with the aforementioned docking port 20.The driving portion 21 connects to the docking member via a plug-in structure. Specifically, the outer circumference of the driving portion 21 and the inner circumference of the docking port 20 are both formed with ribs spaced along their circumference. These ribs interlock with each other. This docking mechanism is similar to that of the first connector 104 and the second connector 105 and is briefly described here. Alternatively, the driving portion 21 connects to the docking member via magnetic attraction. Specifically, both the driving portion 21 and the docking member are entirely made of magnetic material, and at least one is a magnet, such as a magnet. Alternatively, both components have a magnetic component embedded therein, and at least one of the magnetic components is a magnet, such as a magnet. In another alternative, as shown in FIG31 , the pot lid 5 may not include a movable feed assembly, but instead may include an inclined feed channel 230. For example, the feed channel 230 has a feed slope that slopes downward from the feed inlet 7 to the feed inlet 18. Utilizing gravity to convey materials creates a simple conveying structure that is easy to manufacture. In this solution, the feed inlet 7 can be optionally located on the top wall of the lid 5. When in the discharge position, the material bin discharge portion 33 extends above the lid 5, corresponding to the upper and lower positions of the feed inlet 7. Optionally, a cover plate (not shown) can be provided on the top wall to cover the feed inlet 7. The cover plate is pivotally connected to the top wall. To transfer materials, the cover plate must first be pivoted to open the feed inlet 7. In other alternative solutions (not shown), the lid 5 does not include a material washing bin 13. The inner pot 4 serves as a material receiving container, and materials entering through the feed inlet 7 of the lid 5 are conveyed to the inner pot 4. In one example, the inner pot 4 can serve as a material washing container, and the pot body 3 and / or the lid 5 are equipped with a stirring device, such as a stirring element, so that materials can be washed in the inner pot 4 and cooked thereafter. Another example is that the ingredients are wash-free and are directly cooked after being fed into the inner pot 4. The above embodiments describe the material box 22 feeding the material into the pot lid 5 via the discharge port 23. However, in other alternatives (not shown), the material box 22 can also feed the material into the pot body 3 via the discharge port 23. Specifically, the pot lid 5 does not include a feeding device 34 or a feeding channel. When the pot lid 5 is opened, the discharge port 23 of the material box 22 forms a feeding passageway between the inner pot 4 and the material box. Specifically, the material box discharge portion 33 forms a feeding passageway between the inner pot 4 and the material box 22 when the pot lid 5 is opened.The material flowing out of the discharge port 23 can be directly fed into the inner pot 4. The material can be washed and cooked in the inner pot 4, or cooked directly. In other alternatives (not shown), the material washing drive device 40 may not be located within the pot lid 5, but rather within the pot body 3 or the material bin 22, connected to the stirring element 17 within the pot lid 5 via a series of transmission structures. In one example, the material washing drive device 40 is located within the pot body 3, and the pot lid 5 is provided with a set of transmission structures connected to the stirring element 17, which are connected to a docking member. The drive portion of the material washing drive device 40 can extend upward from the pot body 3. The drive portion and the docking member are located at corresponding upper and lower positions. When the pot lid is closed, the docking member can dock with the extended drive portion to drive the stirring element. In another example, the material washing drive device 40 is located within the material bin 22, and the pot lid 5 is provided with a set of transmission structures connected to the stirring element 17, which are connected to a docking member. The material washing drive device 40 is movably disposed within the material bin 22, and its drive unit extends from the side of the material bin 22. The drive unit corresponds to the left and right positions of the docking member. When the pot lid 5 is closed, the material washing drive device 40 moves to extend the drive unit, allowing the docking member to dock with the extended drive unit, thereby driving the stirring member. When the pot lid 5 is to be opened, the material washing drive device 40 is moved to retract the drive unit. Similarly, the material feeding drive device 100 may be disposed not within the pot lid 5, but within the pot body 3 or the material bin 22, connected to the conveying assembly within the pot lid 5 via a series of transmission mechanisms. The arrangement is similar to that of the material washing drive device 40 described above and will not be further described for the sake of brevity. In other alternatives not shown, the material washing drive device 40 may be detachable, for example, from the pot lid 5 (or pot body 3 or the material bin 22). This facilitates the user to clean any residue that has flowed into the drive unit 21 of the material washing drive device 40 and facilitates subsequent replacement and maintenance of the material washing drive device 40. Similarly, the feed drive device 100 can be detachable, for example, from the pot lid 5 (or pot body 3 or material bin 22). This facilitates the user to clean residue from the connectors of the feed drive device 100 and facilitates subsequent replacement and maintenance of the feed drive device 100. In other alternatives not shown, the material washing drive device 40 may not be an electrically driven device, but rather an electromagnetically driven device, or a device driven by gas, steam, or thermal energy.In other alternatives not shown, the pot lid can be integrally and detachably connected to the pot body, thereby allowing the pot lid to be removed for cleaning of parts of the pot lid that require cleaning (e.g., the washing bin, the feed device / feed channel), and for easy repair or replacement of damaged parts.
