[0002] The existing automatic cooking device is provided with a rice storage container and a rice washing container. The rice in the rice storage container can be transported to the rice washing container by a conveying device for washing. The washed rice is cooked in an inner pot. The rice storage container has an outlet and a lid for blocking the outlet. In order to realize the automatic discharge of rice from the outlet of the rice storage container, an electric drive device is usually provided at the outlet of the rice storage container to control the opening of the lid. However, due to the provision of the electric drive device, the manufacturing cost is high, and the use cost is high due to the power consumption, and a large space in the cooking device is occupied, resulting in a large product volume.

[0003] Therefore, a material box and a cooking appliance are needed to at least partially solve the above problems. Utility Model Content

[0004] The content of the utility model introduces a series of simplified concepts, which will be further described in detail in the detailed implementation section. The content of the utility model does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

[0007] The feeding bin is raised and lowered between a receiving position and a feeding position located above the receiving position. The feeding bin can be connected to the outlet of the storage bin when it is at the receiving position. The feeding bin is provided with a pushing portion and has a trigger position located between the receiving position and the feeding position.

[0008] When the feeding bin is in the triggered position, the push portion abuts against the closure member in the closed position, and

[0009] When the feeding bin descends from the triggering position to the material receiving position, the pushing part pushes the closing member to move from the closing position to the opening position.

[0010] According to this solution, the material storage bin outlet can be opened by controlling the movement of the feeding bin to drive the closing member, and the closing member can be kept in the open position in the material receiving state, so that the material storage bin outlet is in the open state, which is convenient for automatic material receiving. After the material receiving is completed, the feeding bin rises, and at this time the pushing part does not provide thrust to the closing member, so the closing member can be reset. In this way, it is possible to avoid setting an electric drive device for driving the closing member to move, which saves manufacturing cost and use cost, reduces the number of parts of the cooking appliance, simplifies the product structure, saves installation space, and is conducive to the miniaturization of the product.

[0011] In addition, the feeding bin is lifted and transported, which is convenient for receiving materials at a low position and feeding materials at a high position. This is beneficial to utilizing the space in the height direction of the material box to store materials, reducing the size of the material box in the horizontal direction, and the conveying structure is simple, reducing the production cost.

[0012] Optionally, the storage bin has a storage bin side wall extending vertically, the storage bin outlet is arranged on the storage bin side wall, and the closure moves vertically. According to this solution, the movement direction of the closure can be consistent with the movement direction of the feeding bin, and the two can move up and down synchronously, making it easier to open the closure and the setting method is simple.

[0013] Optionally, the closure is located as a whole on the outside of the storage bin outlet facing the feeding bin, and abuts against the side wall of the storage bin; thus, the closure blocks the storage bin outlet from the outside of the storage bin outlet, and the closure has a simple structure, for example, it is plate-shaped, which is convenient for production and manufacturing. Alternatively, the bottom end of the storage bin outlet is open, and the closure includes a blocking portion and a protruding portion connected to each other, the blocking portion extends inside the storage bin outlet, and the protruding portion protrudes from the storage bin side wall toward the feeding bin side so as to abut against the pushing portion. Thus, the closure can block the storage bin outlet inside the storage bin outlet, and the height position and structure of the protruding portion can be set as needed, with a large degree of design freedom.

[0014] Optionally, the feeding bin has a feeding bin side wall facing the storage bin, and the pusher extends from the feeding bin side wall and protrudes toward the storage bin. According to this solution, the protruding pusher can extend horizontally to the location of the closure, and the feeding bin has a simple structure and is easy to manufacture.

[0015] Optionally, a feeding bin inlet is provided at the top of the feeding bin, the feeding bin inlet is located at the pushing portion, and faces the side where the storage bin is located or faces upward. According to this solution, the feeding bin inlet can be closer to the storage bin outlet, and a material receiving passage is formed between the two to prevent material leakage.

[0016] Optionally, the storage bin has a storage bin side wall, the storage bin outlet is arranged on the storage bin side wall, the side wall of the pusher faces the storage bin side wall and there is a gap between the side wall of the pusher and the storage bin side wall, and the gap ranges from 0.1mm to 1.5mm. According to this solution, the gap can avoid the friction between the feeding bin and the storage bin side wall, thereby avoiding the feeding bin from getting stuck during movement, and the gap cannot be too large to avoid leakage of materials from the gap.

[0017] Optionally, a feeding bin outlet is provided at the bottom of the feeding bin, and the feeding bin outlet faces away from the side where the storage bin is located. According to this solution, the feeding bin can feed materials on one side and discharge materials on the other side in the left-right direction. When the feeding bin is in the material receiving position, it is located at the bottom of the material box, and the storage bin outlet is higher than the inner bottom surface of the feeding bin; thus, the material can be fed into the feeding bin by its own gravity. The feeding bin has a feeding bin inlet, and the diameter of the feeding bin inlet is larger than the diameter of the storage bin outlet; thus, when the feeding bin inlet is connected to the storage bin outlet, the material flows out from the small opening and flows into the large opening without hindrance, and the material discharge is smoother and more efficient. The storage bin outlet includes straight edges and / or curved edges, or has circular edges, the length L1 of the straight edges ≥5mm, the arc length L2 of the curved edges ≥5mm, the diameter D of the circular edges ≥5mm, and the area S of the storage bin outlet ≥25mm 2 As a result, the storage bin outlet is larger, material discharge is smoother and more efficient.

[0018] Optionally, a biasing member is provided in the material box, the biasing member is located at the lower side of the storage bin, and is configured to provide a biasing force to the closure member to keep the closure member in a closed position. According to this solution, with the help of the biasing member, when the feeding bin is finished receiving the material and rising, the biasing force applied by the biasing member can drive the closure member to gradually move to the closed position, and the outlet of the storage bin is gradually blocked by the closure member while the feeding bin rises, thereby preventing the leakage of materials. In addition, the biasing member keeps the closure member in the closed position, so that the outlet of the storage bin is in a normally closed state.

[0019] Optionally, the feeding bin has a maximum one-way stroke, and the initial position of the feeding bin is located in the middle or upper end of the maximum one-way stroke and avoids the feeding position. According to this solution, the initial position is set at a position avoiding the material receiving and feeding of the feeding bin to avoid triggering related actions at these two positions. The feeding bin is lifted and lowered along a straight line extending vertically. According to this solution, the vertical space of the material box can be used to transport materials, which can reduce the size of the material box in the horizontal direction, which is conducive to optimizing the overall size of the product.

[0020] Optionally, the material box includes a material box shell and a lifting channel located in the material box shell, and the feeding bin is lifted and lowered in the lifting channel.

[0021] Optionally, one of the lifting channel and the feeding bin is provided with a convex rib, and one of the lifting channel and the feeding bin is provided with a groove, and the convex rib slides relatively in the groove. According to this solution, by means of the cooperation restriction of the convex rib and the groove, when the screw rotates, the feeding bin remains fixed, so that the lifting movement can be performed, and the restriction structure is simple, which is convenient for the production and manufacturing of the material box.

[0022] Optionally, a screw arranged vertically is provided in the material box, the screw rotates around its own axis, and the feeding bin is sleeved on the screw and raised and lowered by the rotation of the screw. According to this solution, the rotational motion provided by the driving device is converted into the linear motion of the feeding bin through the screw transmission, the driving structure is simple, the space occupied is small, and it is easy to produce.

[0023] Optionally, the material box includes a position detection device for detecting the position of the feeding bin, the position of the closure and / or the number of rotations of the screw. According to this solution, it is possible to confirm whether the feeding bin is in place when receiving and / or feeding materials, thereby controlling the device for driving the feeding bin to pause, making the control more precise. The material box includes a screw driving device, which is connected to the screw transmission. According to this solution, the material box is built with a device for driving the feeding bin, and feeding can be achieved without the assistance of external equipment.

The washing bin 13 can be connected to the removable cover 9 so as to be removed from the pot cover 5 together with the removable cover 9. This solution enables the washing bin 13 to be removed together with the removable cover 9, and the user is easier to disassemble the washing bin 13 in operation, and saves the steps of disassembling the parts that need to be cleaned, so that the user can clean the washing bin 13 conveniently, and avoid the residual materials from getting moldy and growing insects after a long time.

[0098] In the illustrated embodiment, the sewage pipe 41, the washing bin 13 and the removable cover 9 are constructed as an integral part. When the user wants to clean these parts, these parts can be disassembled at one time, which simplifies the disassembly steps and improves the user experience.

[0099] The sewage tank 39 is detachably connected to the pot body 3, for example, the pot body 3 is provided with a base, and the sewage tank 39 is removably seated on the base. A mutually matching limiting structure is provided between the pot body 3 and the sewage tank 39, so that the sewage tank 39 is fixed more reliably. This solution makes it easy to take the sewage tank 39, so as to dump the sewage and clean the sewage tank 39. The material box 22 also includes a material box cover 44, and the material box shell 29 has a top opening, and the material box cover 44 covers the top opening.

[0100] The cooking appliance 1 also includes a control unit, which can be connected to various electronic control devices in the cooking appliance 1 to control the actions of these electronic control devices. The electronic control devices include a screw drive device 32, a material feeding drive device, a material washing drive device, a water pump, etc. The cooking appliance 1 also has an operation interface, and optionally a wireless module, which can be wirelessly connected to a remote device such as a mobile phone via a wireless network / Bluetooth. The user can set cooking parameters such as material quantity, cooking time, etc. through the operation interface or remote device, and automatically start cooking operations such as measuring materials, adding materials, adding water, washing materials, and cooking after pressing the confirmation button. Default parameters can also be set, and cooking can be completed with one-click operation.

[0101] refer to Figures 3 to 7 The feeding process of the cooking appliance 1 according to the preferred embodiment is described as follows:

[0102] like Figure 3 As shown, the cooking appliance 1 is in the initial state. At this time, the pot cover 5 and the material washing bin cover 16 are both in the closed position, the feeding bin 26 and the material box discharge part 33 are both in the initial position. The storage bin outlet 25 and the feeding bin outlet 28 are both closed.

[0103] When the feeding action is intended, the screw driving device 32 is started and drives the screw 31 to rotate, so that the feeding bin 26 is lowered from the initial position to the material receiving position. Figure 4 As shown, the cooking appliance 1 is in a material receiving state, and the feeding bin 26 is in the material receiving position. At this time, the feeding bin inlet 27 is connected to the storage bin outlet 25, and the material in the storage bin 24 flows into the feeding bin 26. The feeding bin 26 remains in the material receiving position for a predetermined time to ensure that the material fills the feeding bin 26. The predetermined time can be determined based on factors such as the effective volume of the feeding bin 26 and the size of the storage bin outlet 25. After the feeding bin 26 is full, the screw driving device 32 drives the screw 31 to rotate in the opposite direction, so that the feeding bin 26 rises, for example, to Figure 5 A raised position is shown, at which the feeding bin inlet 27 is located above the storage bin outlet 25, and the storage bin outlet 25 can be closed.

[0104] Continue to drive the feeding bin 26 up to Figure 6 The pushing position shown in the figure, at this time, the feeding bin 26 contacts the material box discharge part 33 and as the feeding bin 26 continues to rise, the material box discharge part 33 is pushed to move from the initial position to the discharge position. Figure 7As shown, the cooking appliance 1 is in a discharging state, and the feeding bin 26 is in the feeding position. At this time, the feeding bin outlet 28 is connected to the material box discharging portion 33, and the material in the feeding bin 26 is transported to the feeding port 7 of the pot cover 5 via the material box discharging portion 33. The feeding bin 26 remains in the feeding position for a predetermined time to ensure that the material completely flows out of the feeding bin 26. Then the feeding bin 26 is driven to descend to the initial position, and the feeding bin outlet 28 is closed, and the material box discharging portion 33 can be retracted to the initial position. If it is necessary to feed again, the above steps can be repeated.

[0105] The material flowing in from the feed port 7 of the pot cover 5 falls into the accommodating cavity of the feeding device 34, and the feeding drive device is started and drives the feeding component 36, such as the conveyor belt 37, to move. At this time, the cooking utensil 1 is in a feeding state, and the material is conveyed to the washing bin 13 by the feeding component 36. When the material is completely fed into the washing bin 13, the feeding drive device is turned off to complete the feeding of the material.

[0106] Furthermore, if Fig. 9 and Fig.10 As shown, the bottom of the storage bin 24 is also provided with a closure 45 for closing the storage bin outlet 25, and the closure 45 can move between a closed position for blocking the storage bin outlet 25 and an open position for opening the storage bin outlet 25. The main part of the closure 45 is plate-shaped, so it can also be called a baffle. By opening the closure 45, the feeding bin 26 can be connected with the storage bin outlet 25 when it is in the material receiving position. In different schemes, the closure 45 is in different states when the feeding bin 26 is in the material receiving position. One scheme is that the closure 45 is always in an open state when the feeding bin 26 is in the material receiving position. Another scheme is that when the feeding bin 26 is in the material receiving position, the closure 45 is first in a closed state, and then is moved to an open state. Furthermore, when the feeding bin 26 is at the material receiving position, there is a time period during which the closure 45 is in an open state, so that the feeding bin 26 can be connected to the storage bin outlet 25; wherein the time period can be the entire time period when the feeding bin 26 is at the material receiving position, or it can be a partial time period.

[0107] Specifically, one example is that during the process of the feeding bin 26 moving to the material receiving position, the closure 45 is opened at the same time, so that the feeding bin 26 can be directly connected to the storage bin outlet 25. Another example is that the closure 45 is not opened at the moment when the feeding bin 26 just moves to the material receiving position or for a period of time; the closure 45 is opened during a period of time when the feeding bin 26 remains at the material receiving position, so that the feeding bin 26 can be connected to the storage bin outlet 25. As for the opening method of the closure 45, as shown in the illustrated embodiment, the feeding bin 26 can push the closure 45 to open, thereby utilizing the movement of the feeding bin 26 to open the storage bin outlet 25. Alternatively, a driver can be provided separately, and the driver pushes the closure 45 to open. The following is a specific description using the illustrated embodiment as an example.

[0108] The feeding bin 26 is provided with a pushing portion 48 and has a trigger position located between the material receiving position and the material feeding position. Specifically, the trigger position is located on the upper side of the material receiving position and close to the material receiving position. Fig. 9 The feeding bin 26 is shown to be in the triggered position. When the feeding bin 26 is in the triggered position, the pusher 48 abuts against the closing member 45 in the closed position. When the feeding bin 26 descends from the triggered position to the material receiving position, the pusher 48 pushes the closing member 45 from the closed position to the open position to open the storage bin outlet 25. When the closing member 45 is in the open position, the pusher 48 still abuts against the closing member 45 to prevent the closing member 45 from resetting.

[0109] In this embodiment, the closing member 45 can be driven to open the storage bin outlet 25 by controlling the movement of the feeding bin 26, and the closing member 45 can be kept in the open position in the material receiving state, so that the storage bin outlet 25 is in the open state, which is convenient for automatic material receiving. After the material receiving is completed, the feeding bin 26 rises, and at this time, the pushing part 48 does not provide a thrust to the closing member 45, so the closing member 45 can be reset. In this way, it is possible to avoid setting an electric drive device for driving the closing member 45 to move, which saves manufacturing costs and use costs, and reduces the number of parts of the cooking utensil 1, simplifies the product structure, saves installation space, and is conducive to the miniaturization of the product.

[0110] The storage bin 24 has a storage bin side wall 46 extending vertically, and the storage bin outlet 25 is arranged on the storage bin side wall 46, that is, the storage bin outlet 25 is an opening arranged vertically and faces the side where the feeding bin 26 is located. The closure 45 can move vertically, and the main part of the closure 45 can be parallel to the storage bin side wall 46. The open position of the closure 45 is located at the lower side of its closed position. In this way, the moving direction of the closure 45 can be consistent with the moving direction of the feeding bin 26, and the two can move up and down synchronously, making it easier to open the closure 45, and the setting method is simple.

[0111] In the illustrated embodiment, the closure member 45 is located as a whole on the outside of the storage bin outlet 25 facing the side where the feeding bin 26 is located, and abuts against the storage bin sidewall 46. The closure member 45 can block the storage bin outlet 25 from the outside of the storage bin outlet 25, and the closure member 45 has a simple structure and is easy to manufacture. Alternatively, the bottom end of the storage bin outlet 25 is open, and the closure member 45 includes a blocking portion and a protruding portion connected to each other, and the blocking portion extends into the storage bin outlet 25. Further, the blocking portion extends into the storage bin outlet 25 from the bottom end thereof. The protruding portion protrudes from the storage bin sidewall 46 toward the side where the feeding bin 26 is located so as to abut against the pusher 48. The closure member 45 can block the storage bin outlet 25 in the storage bin outlet 25, and the height position and structure of the protruding portion can be set as needed, and the design freedom is large.

[0112] like Fig.11 As shown, the feeding bin 26 has a feeding bin side wall 49 facing the storage bin 24, and the feeding bin side wall 49 can be parallel to the storage bin side wall 46. The pusher 48 extends from the feeding bin side wall 49 and protrudes toward the storage bin 24, that is, the pusher 48 is a boss formed on the feeding bin side wall 49. When the feeding bin 26 is in the touch position and the material receiving position and between these two positions, the closing member 45 is located between the feeding bin side wall 49 and the storage bin side wall 46, and the pusher 48 is located on the upper side of the closing member 45 and abuts against the upper surface of the closing member 45. The protruding pusher 48 can extend in the horizontal direction to the position where the closing member 45 is located, and the feeding bin 26 has a simple structure and is easy to manufacture.

[0113] The pushing portion 48 is disposed at the top of the feeding bin 26, so that the feeding bin inlet 27 is located at the pushing portion 48. An example is that the feeding bin inlet 27 is on the side wall of the pushing portion 48, and can face the side where the storage bin 24 is located. Alternatively, the feeding bin inlet 27 is on the upper wall of the pushing portion 48, and can face upward. With such an arrangement, the feeding bin inlet 27 can be closer to the storage bin outlet 25, and a material receiving passage is formed between the two to prevent material leakage. There is a gap between the side wall of the pushing portion 48 and the side wall 46 of the storage bin to prevent the feeding bin 26 from getting stuck during movement. At the same time, the gap cannot be too large to prevent material from leaking from the gap. Optionally, the gap ranges from 0.1mm to 1.5mm, preferably from 0.2mm to 1mm.

[0114] As described above, a feeding bin outlet 28 is provided at the bottom of the feeding bin 26, and further, the feeding bin outlet 28 faces away from the side where the storage bin 24 is located. The feeding bin 26 is fed in one side in the left-right direction and discharged in the other side. When the feeding bin 26 is in the material receiving position, it 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 feeding bin 26. Thus, the material can be fed into the feeding bin 26 by its own gravity.

[0115] In order to automatically reset the closure member 45, Fig.12As shown, a biasing member 47 is also provided in the material box 22, and the biasing member 47 is located at the lower side of the storage bin 24 and connected to the closure 45. Specifically, the closure 45 is provided with a mounting portion 51, and a mounting seat 52 is provided at the bottom of the material box 22, and the two ends of the biasing member 47 are respectively connected to the mounting portion 51 and the mounting seat 52. The biasing member 47 can be configured to provide a biasing force to the closure 45 so that the closure 45 remains in the closed position. When the closure 45 is arranged vertically, the biasing member 47 is also arranged vertically and provides an upward biasing force for the closure 45. At this time, the mounting portion 51 protrudes horizontally. Optionally, the biasing member 47 is a telescopic member such as a spring for providing elastic force. With the help of the biasing member 47, when the feeding bin 26 completes the material receiving and rises, the biasing force applied by the biasing member 47 can drive the closure 45 to gradually move to the closed position, and the storage bin outlet 25 is gradually blocked by the closure 45 while the feeding bin 26 rises, thereby avoiding leakage of materials. And the biasing member 47 keeps the closure member 45 in the closed position, so that the storage bin outlet 25 is in a normally closed state.

[0116] As mentioned above, the feeding bin 26 is driven by the screw drive mechanism 30. Fig.11 and Fig.13 As shown, the feeding bin 26 is provided with a screw hole 50. Optionally, the screw hole 50 is close to the side where the feeding bin inlet 27 is located and away from the side where the feeding bin outlet 28 is located. The screw 31 passes through the screw hole 50. The feeding bin 26 has a maximum one-way stroke on the screw 31, and the initial position of the feeding bin 26 is located in the middle of the maximum one-way stroke (see Figure 3 ) or upper end, and avoid the feeding position.

[0117] Fig.14 and Fig.15 The arrangement at the storage silo outlet 25 is shown, wherein Fig.15 In order to show that the storage bin outlet 25 moves the feeding bin 26 upward for a certain distance. The transmission structure between the screw drive device 32 and the screw 31 can be a gear 53. For example, the screw 31 is sleeved with a gear 53, and the end of the screw drive device 32 is sleeved with another gear 53, and the two gears 53 are meshed with each other. The position of the storage bin outlet 25 avoids the position corresponding to the screw 31. Two storage bin outlets 25 are shown for example, correspondingly, see Fig.11 The feeding bin inlet 27 corresponds to the storage bin outlet 25 one by one, and the screw 31 is located between the two feeding bin inlets 27 .

[0118] Optionally, the shape of the feeding bin inlet 27 corresponds to the shape of the storage bin outlet 25. The caliber of the feeding bin inlet 27 is larger than the caliber of the storage bin outlet 25; therefore, when the feeding bin inlet 27 is docked with the storage bin outlet 25, the material flows out of the small opening and flows into the large opening without hindrance, and the material discharge is smoother and more efficient. The storage bin outlet 25 includes straight edges and / or curved edges or has circular edges. The storage bin outlet 25 can be a polygon, such as a rectangle, or a missing circle with curved edges, or a circle. The length L1 of the straight edge is ≥5mm, the arc length L2 of the curved edge is ≥5mm, the diameter D of the circular edge is ≥5mm, and L1, L2 and D can be suitable values ​​such as 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. The area S of the storage bin outlet 25 is ≥25mm 2 , S can be 25mm 2 、28mm 2 , 30mm 2 、32mm 2 、35mm 2 It should be noted that these dimensions are limited to a single storage bin outlet 25.

[0119] like Fig.16 and Fig.17 As shown, the material box 22 also includes a lifting channel 54 located in the material box shell 29, and the screw 31 and the feeding bin 26 are both located in the lifting channel 54, wherein the feeding bin 26 is lifted and lowered in the lifting channel 54. The side wall of the lifting channel 54 used to form the storage bin 24 is the storage bin side wall 46. By providing the lifting channel 54, the storage bin 24 can be opened independently without affecting the lifting of the feeding bin 26, and it is convenient to install the feeding bin 26 and its driving mechanism on the lifting channel 54. The feeding bin 26 is lifted and lowered along a straight line extending vertically, so that the lifting channel 54 is a straight channel extending vertically.

[0120] One of the lifting channel 54 and the feeding bin 26 is provided with a convex rib 55 , and one of the lifting channel 54 and the feeding bin 26 is provided with a groove 56 , and the convex rib 55 slides relatively in the groove 56 . Fig.16 It is shown that the lifting channel 54 is provided with a convex rib 55, which is arranged in the vertical direction; correspondingly, the feeding bin 26 is provided with a groove 56, which is also arranged in the vertical direction. Exemplarily, the convex rib 55 is provided on the two side walls of the lifting channel 54 in the front-to-back direction, and the groove 56 is provided on the two side walls of the feeding bin 26 in the front-to-back direction. With the help of the matching restriction of the convex rib 55 and the groove 56, when the screw 31 rotates, the feeding bin 26 remains fixed, so that the lifting movement can be performed, and the restriction structure is simple, which is convenient for the production and manufacturing of the material box 22.

[0121] Fig.16The horizontal positions of the biasing member 47 and the screw 31 are also shown. The biasing member 47 is located in the middle of the closing member 45, roughly corresponding to the position of the screw 31. The side wall 49 of the feeding bin forms a recess for accommodating the screw 31. The lifting channel 54 is also provided with a vertical groove 57, and the two ends of the closing member 45 are respectively located in the corresponding vertical grooves 57. The closing member 45 is restricted in the vertical groove 57 in the horizontal direction to prevent the closing member 45 from moving horizontally; when the closing member 45 moves, the vertical groove 57 can provide guidance to keep the closing member 45 moving vertically without deflection.

[0122] The material box 22 includes a position detection device 58 for detecting the position of the feeding bin 26, the position of the closure member 45 and / or the number of rotations of the screw 31. Fig.17 As shown, illustratively, the position detection device 58 can be located at the docking position between the feeding bin 26 and the material box discharge part 33, and can detect whether the feeding bin 26 is in the feeding position, thereby confirming that the feeding bin 26 and the material box discharge part 33 are docked in place, and the screw drive device 32 is closed at this time. The position detection device 58 can be a micro switch, a Hall element or an optical coupling sensor, etc. The material box 22 also includes a material box base 59, which is connected to the wall of the lifting channel 54. A part of the material box base 59 is used to form the bottom wall of the storage bin 24. The material box base 59 is located in the material box housing 29, and the biasing member 47, the screw drive device 32, etc. are located in the material box base 59. The top of the lifting channel 54 is open and covered with a channel cover 60, and the channel cover 60 is detachably connected to the top of the lifting channel 54.

[0123] In other alternatives not shown, a movable feeding assembly may not be provided, and an inclined feeding channel is provided in the pot cover 5. For example, the feeding channel has a feeding slope that is inclined downward from the feeding port 7 to the feeding port 18. The material is conveyed by the gravity of the material, and the conveying structure is simple and easy to manufacture. In this scheme, the feeding port 7 can be optionally provided on the top wall of the pot cover 5, and the material box discharge portion 33 extends to the upper side of the pot cover 5 when in the discharge position and corresponds to the upper and lower positions of the feeding port 7. Optionally, the top wall can be provided with a cover plate for covering the feeding port 7. The cover plate can be pivotally connected to the top wall. When feeding is intended, the cover plate needs to be pivoted first to open the feeding port 7.

[0124] In other alternatives not shown, the material washing bin 13 is not provided in the pot cover 5, and the inner pot 4 is used as a material receiving container, and the material entering from the feeding port 7 of the pot cover 5 is conveyed to the inner pot 4.
