The washing bin assembly 200 also includes a washing bin fitting 230 and a mount 240. The washing bin matching part 230 can be connected with the mounting base 240. Part or all of the mounting base 240 can be movably arranged on the main body 210 of the washing bin along a straight line. In the illustrated embodiment, part of the mount 240 is movable along a straight line. The stirring member 19 is located in the washing chamber 211 and connected to the mounting base 240, and the stirring member 19 is rotatable with the mounting base 240 relative to the washing bin main body 210 around the first rotation axis Ax1.

The washing bin driving part 320 is arranged on the transmission main body 310, for example, it can be installed to the transmission main body 310 by means of screw connection or the like. There may be a magnetic force between the washing bin matching part 230 and the washing bin driving part 320. When the transmission body rotates, under the action of magnetic force, the mounting base 240 and the agitator 19 on it rotate; Moves to open and close the wash bin lid 270. The transmission main body 310 has a non-driving position (for example, the different blanking states shown in Fig. 6 and Fig. 7 ), which makes the washing bin matching part 230 and the washing bin driving part 320 out of linkage, and makes the washing bin matching part 230 and the washing bin The driving position of the bin driving member 320 linkage. The driving positions include the first driving position (such as the states shown in Figure 3 to Figure 5) and the second driving position (the blanking state shown in Figure 8). The first driving position corresponds to the closed position, the second driving position corresponds to the open position, and the non-driving position can be the open position (different blanking states as shown in Figure 6 and Figure 7), or the closed position (such as Figure 2 initial position), of course, in other implementation manners, the initial position may be set to the open position. Wherein, the first position can be a non-driving position, which includes an initial position and an intermediate position (different blanking states as shown in Figure 6 and Figure 7); the second position can be a driving position and includes a first driving position and a second driving position .

It should be noted that, for ease of understanding, Fig. 6 and Fig. 9 show the In the transition state, the installation seat 240 of the washing bin cover 270 is under the stress unbalanced in this transition state. A non-contact transmission is formed between the washing bin assembly 200 and the transmission assembly 300. When washing materials in the washing chamber 211, the washing water exists in a space isolated from the transmission assembly 300 and does not contact the transmission assembly 300. Thus, it is possible to prevent the transmission assembly 300 from being soiled by washing water. Compared with the mechanical transmission method, the non-contact transmission method does not need to clean the transmission structure, which can improve the user experience. In this embodiment, the feeding bin 110 and the transmission assembly 300 can produce a synchronous movement stroke, and the transmission assembly 300 and the washing bin cover 270 can produce a cooperative movement, so that only one driving device for driving the feeding bin 110 to move can be provided. After the three linear movements of the feeding bin 110 , the transmission assembly 300 and the washing bin cover 270 are completed, the movement of the feeding bin 110 and the opening and closing of the discharge port 212 can be realized.

The washing bin driving part 320 may include a translation driving part 32L, and the translation driving part is arranged on the transmission main body 310. Both the translation driving part 321 and the translation matching part 231 are magnetic components, and there may be a magnetic force between them. When changing the state of the translation drive part 321 to change the magnetic force between the translation fitting part 231 and the translation drive part 321, the washing bin cover 270 is in the open position of opening the discharge port 212 and the closure of the cover discharge port 212 Move between locations. The transmission assembly 300 and the washing bin cover 270 can realize cooperative movement through magnetic force. When the transmission main body 310 is moved, the washing bin cover 270 can be opened and/or closed by magnetic force, so that the action of opening and closing the discharge port 212 can be realized. In one embodiment, when the state of the translational driving member 321 is changed, the washing bin cover 270 moves from the open position to the closed position. Thus, with the aid of the magnetic force between the translation fitting 231 and the translation drive 321, the washing bin cover 270 can be closed. In another embodiment, when the state of the translational driving member 321 is changed, the washing bin cover 270 moves from the closed position to the open position. Thus, with the aid of the magnetic force between the translation fitting part 231 and the translation driving part 321, the opening of the washing bin cover 270 can be realized. In the illustrated embodiment, when changing the state of the translational drive 321, the washing bin cover 270 moves from the open position to the closed position and from the closed position to the open position.

The magnetic member may include at least one of a magnet, an electromagnet, iron, a turntable, a drill, ferritic steel, martensitic steel, and austenitic-ferritic dual phase steel. Optionally, the magnets can be permanent magnets. Optionally, at least one of the translation matching part 231 and the translation driving part 321 may be a magnet. For example, the translation matching part 231 is a magnet; the translation driving part 321 is a magnet, an electromagnet, iron, a car standard, a drill, a ferritic steel, a martensitic steel, or an austenitic-ferritic dual-phase steel. one. An example is that both the translation matching part 231 and the translation driving part 321 are magnets, so that a relatively large magnetic force can exist between the translation matching part 231 and the translation driving part 321 and the state is stable. Another example is that the translation fitting part 231 is iron, lathe, drill, ferritic steel, martensitic steel, austenitic-ferritic duplex steel, and the translation driving part 321 is a magnet. Since the magnetism of iron, lathe, drill, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel is not affected by high temperature, it can avoid the high temperature during cooking from affecting the translational fitting 231 Magnetic, so that its properties remain unchanged. Optionally, at least one of the translation fitting part 231 and the translation driving part 321 is an electromagnet. When the washing bin cover 270 and the agitating member 19 are both arranged on the same mounting base 240, considering that the rotation of the mounting base 240 will cause the wires to be entangled, therefore, the translation fitting 231 and the translation driving part 321 are not selected as electromagnets. When the washing bin cover 270 and the stirring member 19 are arranged on different installation seats 240, the switch of the washing bin cover 270 and the rotation of the stirring member 19 are independent, and the translation matching part 231 and the translation driving part 321 can be selected as electromagnets. For an embodiment that does not include an electromagnet, the transmission assembly 300 is movable in a straight line relative to the washing bin main body 210. When the transmission assembly 300 moves to change the magnetic force between the translation matching part 231 and the translation driving part 321, the washing bin cover 270 moves between the open position for opening the discharge port 212 and the closed position for covering the discharge port 212 . For the illustrated embodiment, by controlling the position of the transmission assembly 300 moving up and down, the direction of movement of the washing bin cover 270 is controlled according to the change in the direction of the resultant force of magnetic force and gravity, so that it moves to the open position and the closed position. For the implementation of the electromagnet, when the power state of the electromagnet is changed, the washing bin cover 270 can move in a straight line to open and close the discharge port 212. According to design requirements, the rotating driving member 322 can be located radially outside of the rotating matching member 232 when it is in the driving position.

The upper and lower positions of the translation driving part 321 and the translation matching part 231 are corresponding, and the magnetic poles facing each other are opposite or the same. When the magnetic poles are opposite, the magnetic force between the translation driver 321 and the translation matching piece 231 is a magnetic attraction force, and the washing bin cover 270 is moved by the magnetic attraction force; when the magnetic poles are the same, the translation driver 321 and the translation matching piece The magnetic force between 231 is a magnetic repulsion force, and the washing bin cover 270 is moved by the magnetic repulsion force. For the illustrated embodiment, the magnetic poles of the translation driving member 321 and the translation matching member 231 are opposite to each other, and the magnetic force between the two is a magnetic attraction force.

The movement between the closed positions of the discharge port 212 also belongs to the case where the washing bin cover 270 opens and closes the discharge port 212 . As shown in FIG. 13 and FIG. 17B, the washing bin cover 270 can be kept in the closed position by magnetic connection in the initial state. Specifically, the washing bin assembly 200 may also include a holding member 237 and a holding fitting member 238. The holding member 237 can be arranged on the main body 210 of the washing bin. In other implementations not shown, the holding member 237 can be arranged on the mounting bracket. The installation support frame is connected with the pot cover 4. The installation support frame can be a separate support frame directly fixed on the pot cover 4. Both the retaining member 237 and the retaining engagement member 238 are magnetic members.

The installation bracket 340 supports the rotary drive device 301 upwards. In this embodiment, the rotary drive device 301 can move along a straight line with the transmission body 310, so that the charged rotary drive device 301 can be arranged at a position other than the pot cover 4. Specifically, the transmission support 330 may have a support support surface 332 facing downward, and the support support surface 332 is used to abut against the linkage support surface 13L. When the feeding bin 110 moves between the first position and the second position, the support support The support surface 332 abuts against the linkage support surface 131, so that the transmission assembly 300 can be flat Move steadily. When the feeding bin 110 moves between the second position and the additional position, the bearing support surface 332 is separated from the linkage support surface 131.

The transmission support 330 can be provided with a support center hole 331 and a radially outwardly extending support boss 333_o It can be understood that the center hole 331 of the support is located at the center of the transmission support 330. The feeding bin 110 can be located in the central hole 331 of the support, and the supporting surface 332 of the support is arranged around the central hole 331 of the support. The top of the transmission body 310 can be located between the support boss 333 and the mounting bracket 340, which can limit the linear movement of the transmission body 310 relative to the transmission support 330. The top of the transmission body 310 can be provided with an upwardly protruding gear part 314, and the gear part 314 surrounds the center hole 331 of the support and has a ring of teeth. The output shaft is provided with a transmission gear 302, and the teeth of the transmission gear 302 mesh with the teeth of the gear part 314. The illustrated embodiment schematically shows that there is one transmission gear 302 between the output shaft and the gear part 314, however, the number of transmission gears 302 is not limited, and can be set to two or more as required. The mounting bracket 340 may be provided with a bracket guiding portion 341, and the bracket guiding portion 341 extends along the vertical direction. Referring back to FIG. 10 , the storage bin 13 can be correspondingly provided with a vertically extending guide wall 102, at least a part of the guide wall 102 is located inside the storage bin 13 and connected to the fixed bracket 122, so as to isolate the transmission structure from the space for storing ingredients. open. FIG. 10 schematically shows that the guide wall 102 is connected to the bottom wall of the storage bin 13, a part is located above the bottom wall, and a part extends downward from the bottom wall. The bracket guide part 341 is located in the sliding channel 46 surrounded by the guide wall 102. The mounting bracket 340 may include a bracket base 342 and a bracket stand 343 above the bracket base 342. The bracket base 342 can be provided with a bracket guide part 34L integrally formed with it. The bracket guide part 341, for example, can include three walls connected in sequence, and the bracket stand 343 is located in a roughly square area surrounded by these three walls. And the bracket stand 343 is detachably connected to the bracket base 342 by fasteners such as screws. The rotary drive 301 is mounted to the bracket stand 343 and is also located within the bracket guide 341. The middle part of the bracket stand 343 is provided with a support tube, and the output shaft of the rotary driving device 301 is located in the support tube. The lower end of the support tube is connected to the transmission gear 302 to limit the axial movement of the transmission gear 302. As shown in Fig. 5, Fig. 8, Fig. 21 and Fig. 22, the first axis of rotation Ax1 may be collinear with the second axis of rotation Ax2. The washing cavity 211 is configured to be symmetrical about the center, for example, the shape of the washing cavity 211 can be cylindrical. The central axis of the washing chamber 211 is collinear with the first axis of rotation Ax1. The first axis of rotation Ax1 and the second axis of rotation Ax2 may both extend vertically. The central axis of the washing chamber 211 can also be along the vertical to extend. A plurality of rotating fittings 232 may be arranged at intervals along the circumferential direction of the mounting seat 240, specifically, arranged at intervals along the circumferential direction of the second mounting seat 250. A plurality of rotating driving members 322 are arranged at intervals along the circumferential direction of the transmission main body 310. The plurality of rotating fittings 232 have the same magnetism, and are arranged symmetrically around the center of the first rotating axis Ax1. The magnetic properties of the plurality of rotating driving parts 322 are the same, and they are arranged symmetrically around the center of the second rotating axis Ax2. A plurality of rotating fittings 232 are evenly arranged along the circumferential direction of the mounting seat 240; a plurality of rotating driving members 322 are evenly arranged along the circumferential direction of the transmission main body 310. In this way, the magnetic force received by the second mounting seat 250 in the circumferential direction can be equal and uniform, so that the first rotation axis Ax1 and the second rotation axis Ax2 can be kept collinear. The magnetic properties of the plurality of rotating fittings 232 can also be different, but the number of rotating fittings 232 with different magnetic properties must be equal. Preferably, the different magnetic rotating fittings 232 are arranged evenly and at intervals on the premise that the numbers are equal. For example, a group of first magnetic rotating fittings may be arranged first, and then another group of magnetic rotating fittings may be arranged. Then set a set of first magnetic rotating fittings, and then set a second set of magnetic rotating fittings, so that the intervals are repeated to ensure that the rotating fittings of adjacent two groups have different magnetic properties but the same number, and the number of magnetic bodies in each group The quantity is the same and is greater than or equal to 1, which can be flexibly set according to needs, for example, the quantity can be two, three, four, five or six, and so on. For example, the total number of rotating fittings 232 can be two and evenly arranged, one of the magnets facing outward is the N pole, and the other magnet is facing outward as the S pole. There can be two rotary drives corresponding to this. Or as shown in Figure 22, there are 4 groups of rotating fittings, each group has 3 magnets, and the magnetic poles of one group of 3 magnets facing outward can be set as N poles, and the adjacent group of 3 magnets facing outward The magnetic poles are all set as S poles, and the outward magnetic poles of the rotating fittings are respectively NNN, SSS, NNN, and SSS. Correspondingly, the magnetic properties of the plurality of rotating driving parts 322 matched therewith also need to be different, but the numbers need to be equal and they need to be arranged evenly and at intervals. For example, as shown in FIG. 22, there are 16 rotating driving parts in total, which can be set into 4 groups, and the magnetic poles facing outward of one group of 4 magnets are all set as N poles, and the magnetic poles of the 4 adjacent magnets facing outward are all set as N poles. If it is set as the S pole, the magnetic poles facing outward of the rotary driving member are NNNN, SSSS, NNNN, and SSSS respectively. When rotating, the outward-facing magnetic poles of the NNNN group of rotating driving parts cooperate with the outward-facing magnetic poles of the SSS group of rotating fittings to generate magnetic force, and the outward-facing magnetic poles of the SSSS group of rotating driving parts cooperate with the outward-facing magnetic poles of the NNN group The rotating mating pieces mate to create a magnetic force. Thus, the magnetic force received by the second mounting base 250 in the circumferential direction can be equal in magnitude and uniform. The washing bin assembly 200 can also include limiting parts. The mounting base 240 rotates around the limiting component, and the opposing surfaces of the limiting component and the mounting base 240 abut against each other. In this embodiment, the second mounting base 250 drives the first mounting base 220 to rotate around the limiting component, and the limiting component includes the inner wall 214 and the outer wall 215 of the main body 210 of the washing bin._o The transmission main body 310 is configured in a center-symmetrical shape, specifically a turntable shape as described above.

At this time, the magnetic force between the rotating driving part 322 and the rotating matching part 232 is a magnetic attraction force, and the stirring part 19 is rotated by the magnetic attraction force. As shown in FIG. 22, when the rotary driving member 322 is in the driving position, it is radially offset from the rotating matching member 232, and the magnetic poles facing each other are the same. At this time, the magnetic force between the rotating driving member 322 and the rotating matching member 232 is a magnetic repulsion force, and the stirring member 19 is rotated by the magnetic repulsion force. There are a plurality of rotating driving members 322 arranged at intervals along the circumference of the transmission main body 310. The transmission side wall 312 has a plurality of transmission installation surfaces 315 arranged in the circumferential direction ( FIG. 10 ), the transmission installation surfaces 315 are flat and extend vertically, and the rotary driving member 322 is installed on the transmission installation surfaces 315 .

The second mounting seat 250 has a plurality of seat mounting surfaces 253 arranged in the circumferential direction. The seat mounting surfaces 253 are flat and extend vertically. The rotating fitting 232 is mounted to the seat mounting surfaces 253. One of the rotating matching member 232 and the rotating driving member 322 can be arranged in one row, and the other of the two can be arranged in two rows at vertical intervals. Alternatively, the rotating fittings 232 and the rotating driving members 322 may both be provided in a row, and one of them may be in the shape of a vertically arranged elongated bar.

For the illustrated embodiment, the washing bin cover 270 is in the closed position (as shown in FIG. 2 ) in the initial state, and under this solution, no action is performed on the washing bin cover 270 during the process of preparing materials. Before performing the feeding step, the feeding bin and the transmission assembly 300 need to be moved from the storage position to the mating position. In this embodiment, the matching positions may be the first driving position, the second driving position and the additional position. The control device controls the feeding bin to drive the transmission assembly 300 to move downward from the storage position to the distribution position. fit position. Specifically, in order to directly wash the materials after feeding, the control transmission assembly 300 moves downward from the storage position to the first driving position.

S2 Perform material feeding to send materials and water into the material washing chamber 211 through the material inlet. Performing the feeding step includes increasing the first magnetic force to keep the wash bin cover 270 in the closed position. This enables the washing bin cover 270 and the bin cover mounting seat to bear the weight of larger materials and water. It should be noted that, for the illustrated embodiment, the washing bin cover 270 is in the closed position in the initial state, and in this solution, the first magnetic force can be increased. In one embodiment, the first magnetic force is generated by an electromagnet. The control method further includes increasing the current or turning on the current to increase the first magnetic force. The control device changes the state of the current to realize the closing of the washing bin cover 270 . In another embodiment, the first magnetic force is generated by a magnet. The control method further includes controlling the transmission assembly 300 to move downward to increase the first magnetic force, specifically to move downward to the first driving position. The control device controls the movement of the transmission assembly 300 to reduce the distance between the transmission assembly 300 and the cover mounting seat, so as to realize the closing of the material washing compartment cover 270 . For the embodiment in which the washing bin cover 270 is in the open position in the initial state, the first magnetic force has been increased in the step of preparing for loading materials, thus, the first magnetic force does not need to be increased again in the step of loading materials. The step of feeding materials includes performing unloading, which is used to send materials into the washing chamber 21L. The control device controls the feeding bin 110 to move down to a matching position where the feeding channel communicates with the storage bin 13 and the washing chamber 211. That is, the additional position (as shown in FIG. 4 ) is used to send the materials in the storage bin 13 into the washing chamber 211 . The feeding bin 110 extends into the material washing chamber 211 through the material inlet 201 , the material inlet 111 located on its side wall can communicate with the storage bin 13 , and the material outlet 112 located on its side wall can communicate with the material washing chamber 211 . After the unloading is completed, the control device controls the feeding bin 110 to move upwards to a position where the feeding channel is not communicated with the washing chamber 211, such as the first driving position in the second position (as shown in Figure 5) □ Carry out the feeding step Including performing water intake and supplying water to the washing chamber 211. In one embodiment, water is supplied to the washing chamber 211 through the water inlet channel of the feeding bin 110 and the material inlet 201 . The order of water supply and cutting is not in particular order. It is preferable to feed water after feeding, or feed water first, or feed water during feeding to save time. It should be noted that the water outlet 113 is located on the lower surface of the feeding bin 110. When water is being fed, the position where the feeding bin 110 is located above the washing chamber 211 can be used as a position communicating with the washing chamber 211, such as an additional position, A first drive position and a second drive position. When the feeding bin 110 is in these positions, water can be supplied to the washing chamber 211. The water in the fresh water tank 81 can be supplied into the washing chamber 211 through the water inlet pipe and the water inlet channel of the feeding bin 110 . replaceable Alternatively, the water inlet assembly may include a water inlet pipe and a water pump, and the control method includes controlling the water inlet assembly to supply water to the washing chamber 211. The control device can control the water pump to start water intake and stop water intake. Another alternative embodiment is that water can be directly supplied to the washing chamber 211 via a water inlet device such as a water inlet pipe. After the feeding is completed and the feeding bin 110 is moved upwards to a position where the feeding channel is not connected to the washing chamber 211 after the water feeding is completed or before the water feeding is completed, the transmission of the materials is terminated. There may be one material inlet 201 , and the material and water are sent into the washing chamber 211 from the one material inlet 201 . Alternatively, there may be two or more material inlets 201, and materials and water are fed into the washing chamber 211 from different material inlets 201 respectively.

S3 Execute material washing to clean the materials in the material washing chamber 211. The control transmission assembly 300 can drive the agitator 19 to rotate to carry out the operation of throwing the material during washing. For the illustrated embodiment, the control method also includes controlling the transmission assembly 300 to move to the first driving position to prepare for throwing the material during washing. It can be understood that if the transmission assembly 300 has already moved to the first driving position during the step of preparing for feeding materials and executing the step of feeding materials, this operation does not need to be performed during the step of washing materials. Specifically, the control device controls the transmission assembly at the first driving position 300 drives the mounting seat of the stirring element to drive the stirring element 19 to rotate for washing operation. In the step of washing materials, the transmission assembly 300 has a second magnetic force between the first driving position and the mounting seat of the stirring member. Through the second magnetic force, the transmission assembly 300 drives the stirring member mounting seat to drive the stirring member 19 to rotate. Specifically, the transmission main body 310 at the first driving position is controlled to rotate around the second rotation axis, and the agitator mounting seat is subjected to circumferential magnetic force to rotate together with the transmission main body 310 around the second rotation axis, so as to drive the Stirrer 19 rotates. The transmission assembly 300 and the stirring member 19 rotate synchronously, and the rotation of the stirring member 19 can realize washing. For the illustrated embodiment, the second mounting base 250 is subjected to the second magnetic force from the transmission assembly 300, and when the transmission body 310 of the transmission assembly 300 rotates, the first mounting base 220 as the stirring member mounting base is under the action of the second magnetic force Rotate together with the second mounting base 250 to drive the stirring member 19 to rotate. It should be noted that there is no limitation on the order of the steps of feeding, feeding, and washing in the above-mentioned feeding, and they can be performed sequentially, that is, feeding-water-washing; water can also be fed during the feeding process. , and wash the material after entering the water; it can also be to enter the water before the material is unloaded, and to wash the material after the material is unloaded; it can also be to unload the material and enter the water during the washing process, etc.

S4 Execute the sewage discharge and discharge the sewage in the washing chamber 211 after the washing is completed, specifically from the bottom of the washing chamber 211 The sewage outlet is discharged to the _sewage tank 48 through the sewage pipe 10. The drainage method can be gravity drainage and siphon drainage. For the siphon drainage scheme, the step of performing drainage also includes supplying water to the washing chamber 211 until the water level in the washing chamber 211 is higher than the highest part of the siphon pipe, so as to trigger siphon drainage.

S5 To perform blanking, it is necessary to open the washing bin cover 270 and then blank. The blanking step of this embodiment includes reducing the first magnetic force between the cover mounting seat and the transmission assembly 300, so that the washing cover 270 moves downward from the closed position to the open position due to gravity, and the cleaned material into the pot. The washing bin cover 270 is driven by magnetic force to open the discharge port 212, so that the opening action of the washing bin cover 270 can be easily realized, the work efficiency is high, the automation level is high, and the washing water can be avoided from dirtying the transmission assembly 300 , Reduce the cleaning workload of the washing bin components and improve the user experience. In one embodiment, the first magnetic force is generated by an electromagnet, and the control method further includes reducing the current or cutting off the current to reduce the first magnetic force; the control device changes the state of the current to realize the opening of the washing bin cover 270 . In another embodiment, the first magnetic force is generated by a magnet, and the control method further includes controlling the transmission assembly 300 to move upward to reduce the first magnetic force. The control device controls the movement of the transmission assembly 300 to reduce the distance between the transmission assembly 300 and the cover mounting seat, so as to realize the opening of the washing compartment cover 270 . For the solution of magnets, the control method further includes controlling the transmission assembly 300 to move to the second driving position to prepare for material throwing during material blanking. Specifically, the transmission assembly 300 is controlled to move from the first driving position to the second driving position. The switching of the transmission assembly 300 between the first driving position and the second driving position includes controlling the transmission assembly 300 to move upwards by a first distance L1 from the first driving position to the non-driving position to reduce the first magnetic force, so that the washing bin Lid 270 moves downward from the closed position to the open position due to gravity. The transmission assembly 300 is controlled to move down the second distance L2 from the non-driving position to the second driving position, and the washing bin cover 270 remains in the open position. When the material washing bin cover 270 is in the open position, the material washing chamber 211 communicates with the inner pot 3 . The first distance L1 is greater than the second distance L2. That is to say, the second driving position is located above the first driving position. Such control can not only realize the opening of the discharge port 212 and the switching between the material washing station and the material blanking station, so that the material washing process can be carried out smoothly, but also can reduce the height of the transmission body 310, and optimize the cooking utensil 1. structure. The control method of this embodiment can design the height of the transmission assembly 300 to a desired smaller size. On the one hand, the distance between the transmission assembly 300 and the pot cover 4 can be reasonably designed, so that the placement of the pot body 2 and the pot cover 4 and It is easier to take and operate, and will not touch the body assembly 11, avoiding damage to the body assembly 11; on the other hand, the overall height of the cooking appliance 1 can be reduced, which is beneficial to the miniaturization of the product. The first distance L1 may be 6mm~100mm, for example, 6mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm. The difference L1-L2 between the first distance and the second distance can be 5mm~20mm, for example, 5mm, 8mm, 10mm, 12mm, 14mm, mm, 16mm, 18mm, 20mm. The transmission body of the transmission assembly 300 of _this solution The height of 310 can be reduced by a value less than or equal to the first distance L1, which is equal to the distance L1 from the open position of the washing bin cover 270, relative to the switching method of directly moving it from the first driving position to the second driving position. In the solution of the moving distance to the closed position, the height of the transmission body 310 is reduced by a dimension equal to the first distance L1, and the first distance L1 is greater than that of the movement of the washing bin cover 270 from the open position to the closed position. In the distance scheme, the height of the transmission body 310 is reduced by a dimension smaller than the first distance L1. Optionally, the first distance L1 may be 20mm˜30mm. A preferred example is that the first distance L1 is 25mm, and the second distance is 20mm. Another preferred example is that the first distance L1 is 25 mm, and the second distance is 5 mm. The beneficial effects of this control method will be described below in a comparative manner. As an example, it may be defined that: the stroke of the washing bin cover 270 moving between the open position and the closed position is a, as shown in FIG. 7 . It should be noted that the stroke a is generally related to the ratio of the size of the washing bin cover 270 to the size of the discharge opening. The stroke of the transmission body 310 moving between the washing station and the blanking station is bo, and the effective coupling width between the translation matching part 231 and the translation driving part 321 is L. The thickness of the bin body top wall 216 of the washing bin body 210 is t, as shown in FIG. 7 . The height of the transmission assembly 300, specifically the height of the transmission body 310 is H, as shown in FIG. 1 . The height H satisfies the following relationship: H=L+b+t. It can be seen that the stroke b decreases and the height H decreases accordingly. For the embodiment in which the transmission assembly 300 is directly switched from the washing station to the blanking station, in order to open the washing bin cover 270 at the same time when switching, the stroke b1 includes the stroke a. That is, the height Hl=L+bl+t. For the embodiment in which an action is added to directly switch the transmission assembly 300 from the washing station to the blanking station in this embodiment, the stroke b2 does not include the stroke a. That is, the height H2=L+b2+t. Therefore, H1-H2=a, therefore, the height H of the transmission body 310 in this embodiment is reduced by a dimension a. When the overall height of the cooking utensil 1 is constant, the distance D (as shown in FIG. 1 ) between the transmission assembly 300 and the main body 210 of the washing bin 4 on the pot cover 4 can increase the dimension a, so that the pot body 2 and the pot cover 4 Easy to place and take. Of course, if needed and/or desired, the reduced dimension a of the transmission assembly 300 can be designed to reduce the overall height of the cooking utensil 1, and to reduce the distance between the transmission assembly 300 and the pot cover 4 Adjust the distance D to an appropriate value. As an example, stroke a=20mm, stroke bl=22mm, coupling width L=10mm, thickness t=6mm. Height H 1 =L+b 1 +t=38mm, height H2=Hl-a=18mm. When the material washing bin cover 270 is opened and the transmission assembly 300 is located at the blanking station, the agitator 19 can be controlled to rotate to perform material rejection during blanking. Specifically, the transmission assembly 300 located at the second driving position is controlled to drive the stirring member mounting seat to drive the stirring member 19 to rotate together. In the step of performing the blanking, the transmission assembly 300 has a second magnetic force between the first driving position and the mounting seat of the stirring element. Through the second magnetic force, the transmission assembly 300 drives the stirring member mounting seat to drive the stirring member 19 to rotate. Specifically, the transmission main body 310 of the transmission assembly 300 at the second driving position is controlled to rotate around the second rotation axis, and the stirrer mounting seat is subjected to circumferential magnetic force to rotate together with the transmission main body 310 around the second rotation axis, thereby driving the stirrer 19 Rotate thereupon to realize the action of throwing the material during blanking, so as to drop the material in the washing chamber 211 into the inner pot 3.

S6 Perform reset to reset the washing bin cover 270, the transmission assembly 300 and the feeding bin 110. It should be noted that the reset action can be performed in any stage after blanking. For example, water can be added to the inner pot 3 before reset, and the washing bin cover 270, transmission assembly 300 and feeding bin 110 can be reset after adding water. For example, reset after cooking. Reset of the washing bin cover 270: The washing bin cover 270 of this embodiment is in the closed position in the initial state, and when it is reset directly after blanking or after cooking, if the washing bin cover 270 is currently in the open position, then It is necessary to perform a reset of the washing bin cover 270 . Executing the reset includes: controlling the transmission assembly 300 to move from the second driving position to the first driving position, and the washing bin cover 270 is moved from the open position to the closing position by upward magnetic force to realize the reset of the washing bin cover 270 . To reset directly after blanking or after cooking, if the material washing compartment cover 270 is currently in the closed position, no action is performed on the material washing compartment cover 270 during the reset process. Resetting of the feeding bin 110 and the transmission assembly 300: the feeding bin 110 can be controlled to drive the transmission assembly 300 to move upward from the matching position to the storage position, so as to reset the feeding bin 110 and the transmission assembly 300 _o The feeding bin 110 and/or the transmission assembly 300 are in the storage position Some or all of them are housed inside the body components. For the illustrated embodiment, the feeding bin 110 is substantially all or most stored inside the body assembly at the storage position, and the rotary drive device 301 of the transmission assembly 300 is almost all or mostly stored inside the body assembly. In the above related steps, the control method further includes: controlling the feeding bin 110 to move up and down to drive the transmission assembly 300 to move along a straight line; controlling the linear drive device 120 to drive the feeding bin 110 to move along a straight line; controlling the transmission assembly 300 to move up and down together with the rotary drive device To move, specifically to control the feeding bin 110 to drive the transmission assembly 300 to move up and down together with the rotary drive device; to control the rotary drive device 301 to drive a part of the transmission assembly 300 to rotate, specifically to control the rotary drive device 301 to drive the transmission body 310 of the transmission assembly 300 to rotate. The movement of the transmission assembly 300 is realized by controlling the movement of the feeding bin 110 . Specifically, the control device controls the linear drive device 120 to drive the feeding bin 110 to move along a straight line, and the feeding bin 110 is engageable with the transmission assembly 300 to drive the transmission assembly 300 to move up and down. In the reset step, the feeding bin 110 is controlled to move upward to drive the transmission assembly 300 to move upward together to the storage position. In the steps of washing and dropping materials, the rotation driving device 301 is controlled to drive the transmission main body 310 of the transmission assembly 300 to rotate, thereby driving the material washing bin cover 270 and the stirring member 19 on it to rotate. For the illustrated embodiment, the agitator 19 and the material washing bin cover 270 are both arranged on the first mount 250, and in this embodiment, the control method further includes driving the material washing bin cover 270 together with the agitator 19 in the open position and closed Move between locations. In other embodiments, the cover mounting base and the agitator mounting base are separate components and are set independently. In this embodiment, the control method further includes independently driving the washing bin cover 270 to move between the open position and the closed position. , and independently drive the stirring member 19 to rotate. Add water to the washing chamber 211 to add water to the pot body after performing the blowdown step. Water can be added to the inner pot 3 via the washing chamber 211 after the sewage discharge and before the material is discharged, or during or after the material is discharged. In one embodiment, the cooking operation is performed directly after performing the blanking step. In another embodiment, the control unit can control the cooking utensil to cycle through the steps of feeding, washing, draining, and dropping among the above steps, and the specific number of cycles is determined by the amount of material selected by the user. For example, when one cup of rice is selected, the above steps are cycled once; when two cups of rice are selected, the above steps are cycled twice; when N cups of rice are selected, the above steps are cycled N times. Enter the cooking step after N steps. The entire cleaning process of the cooking appliance 1 in the first embodiment will be described below with reference to FIGS. 2-9 : As shown in FIG. 2 , the cooking appliance 1 is in an initial state. At this time, the feeding bin 110 and the transmission assembly 300 are all in the initial position in the first position, the outlet of the feeding bin 110 and the storage bin 13 and the material inlet 201 of the washing bin assembly 200 are not connected, and the washing bin cover 270 is in the Close position. In the initial state, the force relationship of the washing bin cover 270 is F1+F2 2 G1+G2, wherein F1 is the magnetic force between the translation fitting 231 and the translation driving part 321; F2 is the holding member 237 and the holding fit member 238 between the magnetic Force; G1 is the total weight of the washing bin cover 270 and the follow-up load that moves along with it in a straight line. In this embodiment, the follow-up load includes at least the first mounting seat 220, the translation fitting 231 and the stirring member 19; G2 is the weight of water and materials in the washing chamber 211. It can be understood that G1 is a fixed value, and F1, F2 and G2 are variable values. In this state, F1 is small, and may even be close to or equal to 0. When Fl=0, F2 2 G1+G2; F2 is the largest, that is, F2max; G2=0, or G2 is a small amount of residue after cleaning on the washing chamber 211 weight of water. When the unloading operation is intended, the linear driving device 120 can firstly drive the screw 121 to move, so that the screw 121 can drive the feeding bin 110 to move down to the first driving position in the second position. As shown in Fig. 3, the cooking utensil 1 is in a state of preparing for feeding. At this time, the feeding bin 110 and the transmission assembly 300 are all in the first driving position in the second position, and the outlet of the feeding bin 110 and the storage bin 13 and the material inlet 201 of the washing bin assembly 200 are still not connected, and the washing bin Lid 270 is still in the closed position. In the state shown in FIG. 3, the force relationship of the washing bin cover 270 is F1+F2>G1+G2, wherein F1 and F2 are the largest, namely Flmax, F2max, and G2 is the same as the initial state. Thus, the washing bin cover 270 is subjected to an upward magnetic force and the washing bin assembly 200 is magnetically connected in a radial direction. Then the linear drive device 120 can continue to drive the screw 121 to move, the feeding bin 110 continues to move downwards and extends into the washing chamber 211 without the transmission assembly 300 moving accordingly. As shown in Fig. 4, the cooking utensil 1 is in an unloading state. At this time, the feeding bin 110 is in the additional position, the transmission assembly 300 is in the first driving position in the second position, the outlet of the feeding bin 110 and the storage bin 13 and the inlet 201 of the washing bin assembly 200 are still connected, and the washing The lid 270 is still in the closed position. The material in the storage bin 13 enters the feeding bin 110 through the material inlet 111, and then enters the material washing chamber 211 through the material outlet 112 to perform the unloading action. The amount of material flowing into the washing chamber 211 can be calculated by time, and the cooking appliance controls the time that the feeding bin 110 is in the additional position according to the amount of material required by the user, so as to realize quantitative feeding. Water can also be supplied to the washing chamber 211 in this loading state, and the loading and water supply can be performed at the same time, or the water supply action can be performed after the loading is completed. The clean water in the clean water tank 81 enters the feeding bin 110 through the pipeline and the water inlet 113, and then enters the washing chamber 211 through the water outlet 114. When the blanking and water supply are completed, the stress relationship of the washing bin cover 270 is F1+F2>G1+G2, wherein F1 and F2 are Flmax and F2max, and G2 is the weight of water and materials. When the unloading operation is completed, the linear driving device 120 drives the screw 121 to move again, and the screw 121 drives the feeding bin 110 to move upward to the first driving position in the second position, as shown in FIG. 5 . In the state shown in FIG. 5 , water can be supplied to the washing chamber 211, or in the state shown in FIG. 4 , water can be supplied to the washing chamber. When water is supplied in the state shown in Fig. 5, the weight of G2 increases. After the water supply is completed, the rotation driving device 301 can drive the transmission body 310 to rotate, and then the rotation driving member 322 cooperates with the rotation The magnetic force between the components 232 can drive the second mounting base 250 to rotate, and then drive the first mounting base 220 and the stirring component 19 on it to rotate together to perform washing action. It can be understood that, for the illustrated embodiment, the water level in the washing chamber 211 is lower than the highest part of the sewage pipe 10 during washing. In other embodiments not shown, a separate electromagnetic valve for opening and closing the sewage outlet 213 can be set, and whether to drain water can be directly controlled by directly controlling the opening and closing state of the electromagnetic valve. The water level in the material chamber 211 must be lower than the highest part of the sewage pipe. For the illustrated embodiment, when the washing action is completed and the water is intended to be drained, water is first supplied to the washing chamber 211 until the water level in the washing chamber 211 is higher than the highest part of the sewage pipe 10, and the siphon principle is used for drainage. And the highest position of the drainage channel will have a velocity head, thereby forming a full flow of the sewage pipe 10 . When the water level dropped to the highest position lower than the sewage pipe 10, since the drainage passage here was in a full flow state, at this moment, the water level in the washing chamber 211 was higher than the water level of the water outlet 114 of the sewage pipe 107. According to Nut's principle, the outlet of the sewage pipe 107 will have a velocity head at this time, which can drain the water in the washing bin. When the drainage is completed, the force relationship of the washing bin cover 270 is F1+F2>G1+G2, where F1 and F2 are Flmax and F2max, and G2 is the weight of the material after water absorption and a small amount of residual water. If necessary, water can also be added after draining for cooking; in this case, G2 is the weight of the material and water after absorbing water. The actions of water supply, material rejection and drainage during washing can be performed repeatedly to realize multiple washing of a single material. When the draining action is completed and material is to be dropped, the linear drive device 120 drives the feeding bin 110 to move upward to the intermediate position in the first position, as shown in FIG. 6 . In the state shown in FIG. 6, the force relationship of the washing bin cover 270 is F1+F2<G1+G2, wherein F1 decreases, that is, FKFlmax. F2 is F2max, and G2 is the same as when the drainage is completed. Due to F1+F2<G1+G2, the force on the washing bin cover 270 is unbalanced, it cannot be kept in the closed position and will move downward, and the discharge port 212 will be opened. The cooking appliance switches from the state shown in FIG. 6 to the state shown in FIG. 7 quickly, that is, the washing bin cover 270 moves down to the open position, and during this process F1 continues to decrease, and F2 decreases. As shown in FIG. 7 , the washing bin cover 270 has been in the open position, and the discharge port 212 has been opened. At this time, some materials and/or water will fall into the inner pot 3, and G2 will decrease. In the state shown in Fig. 7, the stress relationship of the washing bin cover 270 is F1+F2VG1+G2, wherein FKFlmax. F2 is the smallest, ie F2min, and G2 is the weight of the remaining water-absorbing materials and a small amount of residual water. Then the linear driving device 120 drives the screw 121 to move the transmission body 310 downward from the middle position to the second driving position in the second position. At this time, as shown in FIG. 8 , the cooking utensil 1 is in a blanking state. There is a distance d1 between the translational driving part 321 and the translational matching part 231, and the stress relationship of the washing bin cover 270 is F1+F2VG1+G2, where FKFlmax. F2 is F2min, G2 is the same as the state shown in Figure 7 The same, so that during the blanking process, the washing bin cover 270 is always kept in the open position. Then the rotating drive device 301 drives the transmission main body 310 to rotate again, so that the agitator 19 rotates, starts to throw the material, and performs a material dropping action, and the material falls into the inner pot 3 quickly under the action of centrifugal force. G2 continues to decrease during material rejection. After material rejection is completed, the force relationship of the washing bin cover 270 is F1+F291+G2, wherein FKFlmax. F2 is F2min, and G2 is the weight of a small amount of residual water. As an example, the difference between F1+F2 and G1+G2 can be 30g at this time _. When the blanking action is completed, when it is necessary to reset, the linear drive device 120 continues to drive the screw 121 to make the transmission body 310 start from the second drive position.

The cooking appliance of the fourth embodiment has the same structure and/or structure as the cooking appliance 1 of the first embodiment except for the transmission structure, the stirring member 19 and the washing bin cover 270 . Therefore, elements having substantially the same functions as those in the first embodiment will be numbered the same here, and will not be described and/or illustrated in detail for the sake of brevity. In this embodiment, as shown in FIG. 31, the discharge port 212 is normally open.

In the illustrated embodiment, the output shaft is directly inserted into the installation hole of the transmission body 310 . The control method of this embodiment is roughly the same as the control method of the first embodiment, the main difference is:

S1 is ready to feed the material, and the washing bin cover 270 needs to be closed. Thus, the step of preparing for feeding includes increasing the first magnetic force between the cover mounting seat and the transmission assembly 300, so that the washing bin cover 270 moves upwards from the open position to the closed position. This realizes that the washing bin cover 270 is driven by magnetic force to move to close the discharge port, and the closing action of the washing bin cover 270 is easily realized, the work efficiency is high, the automation level is high, and the transmission assembly 300 can be avoided from being dirty by washing water. Reduce the cleaning workload of the washing bin components and improve the user experience. In one embodiment, the first magnetic force is generated by an electromagnet. The control method also includes increasing the current or turning on the current to increase the first magnetic force. The control device changes the state of the current to realize the closing of the washing compartment cover 270. In another embodiment, the first magnetic force is generated by a magnet. The control method also includes controlling the transmission assembly 300 to move downward to increase the first magnetic force, specifically to move downward to the first driving position. The control device controls the movement of the transmission assembly 300 to reduce the distance between the transmission assembly 300 and the cover mounting seat, thereby realizing the closing of the washing compartment cover 270.

S3 Perform washing. The stirring member mounting seat receives the second magnetic force from the transmission assembly 300. When the transmission main body 310 of the transmission assembly 300 rotates, the stirring member mounting seat drives the stirring member 19 to rotate under the action of the second magnetic force. S6 Execute reset. The washing bin cover 270 of this embodiment is in the open position in the initial state. When it is reset directly after blanking or after cooking, if the washing bin cover 270 is currently in the open position, the process of performing reset No action is performed on the washing bin cover 270 in the middle. If the material washing bin cover 270 is currently in the closed position, then the washing material bin cover 270 needs to be reset. Performing the reset includes: controlling the transmission assembly 300 to move upward from the first driving position, for example, directly moving upward to the storage position, and the washing bin cover 270 is moved from the closed position to the open position by gravity to realize the reset of the washing bin cover 270 . Furthermore, when the feeding bin 110 is controlled to drive the transmission assembly 300 to reset together, the washing bin cover 270 is also reset at the same time. Other steps are substantially the same as the control steps of the first embodiment, and are briefly described for brevity. The whole washing process of this embodiment is roughly the same as that of the first embodiment, so it will be briefly described for the sake of brevity. The difference is that the discharge port of this embodiment is opened in the initial state, and the washing bin cover 270 needs to be closed first. Specifically, Fig. 32 shows that the cooking appliance is in the initial state, at this time, the feeding bin 110 and the transmission assembly 300 are in the initial position in the first position, and the washing bin cover 270 is in the open position. In the initial state, the force relationship of the washing bin cover 270 is FKG1+G2, wherein the minimum of F1 is Fmin; G2=0, or G2 is the weight of a small amount of residual water on the washing chamber 211 after washing. Then the feeding bin 110 and the transmission assembly 300 move down to the first driving position, as shown in FIG. 33 . During this process, F1 increases; in the state shown in Figure 33, the force relationship of the washing bin cover 270 is FDG1+G2, where G2 is the same as the initial state. Since F1>G1+G2, the force on the washing compartment cover 270 is unbalanced, and it cannot be kept in the open position and moved upward to the closed position by the magnetic force. As shown in FIG. 34, the washing bin cover 270 has been in the closed position, and the discharge port 212 has been closed. The cooking utensil switches from the state shown in FIG. 33 to the state shown in FIG. 34 quickly, that is, the washing bin cover 270 moves upward to the closed position. During this process, F1 continues to increase to Flmax, and the force relationship is FDG1+G2. Then the feeding bin 110 continues to move downwards into the washing chamber 211. At this time, as shown in FIG. Unloading is performed in this state. The water supply operation is performed in at least one of the states shown in FIGS. 33 to 35 . When material feeding and water supply are completed, the force relationship of the washing bin cover 270 is F1>G1+G2, wherein F1 is Flmax, and G2 is the weight of water and materials. After finishing the blanking and water supply, the feeding bin 110 moves upwards to the first driving position, as shown in FIG. 36. In the state shown in FIG. The silo cover 270 rotates to perform the action of throwing away materials during washing. Drainage after washing. When the drainage is completed, the force relationship of the washing bin cover 270 is F1>G1+G2, where F1 is Flmax, and G2 is the weight of the material after water absorption and a small amount of residual water. If necessary, water can also be added after draining for cooking; in this case, G2 is the weight of the material and water after absorbing water. The actions of water supply, material rejection and drainage during washing can be performed repeatedly to realize multiple washing of a single material. After the draining operation is completed, the feeding bin 110 and the transmission assembly 300 move upward to the middle position, as shown in FIG. 37 . In the state shown in FIG. 37, the force relationship of the washing bin cover 270 is Fl<G1+G2, wherein Fl decreases, that is, FKFlmax, G2 is the same as when the drainage is completed. Due to FKG1+G2, the force on the washing bin cover 270 is unbalanced, and it cannot be kept in the closed position and will move downward. The cooking appliance switches from the state shown in FIG. 37 to the state shown in FIG. 38 very quickly, that is, the washing bin cover 270 moves down to the open position, and F1 continues to decrease during this process. As shown in Figure 38, the material washing bin cover 270 has been positioned at the open position, and the discharge port 212 has been opened. At this time, some materials and/or water will fall into the inner pot 3, and G2 will decrease. In the state shown in FIG. 38, the stress relationship of the washing bin cover 270 is FKG1+G2, wherein FKFlmax, G2 is the weight of the remaining water-absorbing materials and a small amount of residual water. Then the transmission body 310 moves downward from the middle position to the second driving position in the second position, as shown in FIG. 39 . In the state shown in FIG. 39, the stress relationship of the washing bin cover 270 is FKG1+G2, wherein FKFlmax, G2 are the same as the state shown in FIG. 37. Then the rotating driving device 301 drives the transmission main body 310 to rotate again to make the washing bin cover 270 rotate, and perform the material throwing action during blanking. G2 continues to decrease during material rejection, and after completion of material rejection, the force relationship of the washing bin cover 270 is FKG1+G2, where FKFlmax, G2 is the weight of a small amount of residual water. As an example, the difference between F1 and G1+G2 at this time may be 30g. Then when the blanking is completed, the following actions can be performed. One solution is that the washing bin cover 270 can be closed. That is, the cooking appliance is switched from the state shown in FIG. 39 to the state shown in FIG. 34 . Move the feeding bin 110 and the transmission assembly 300 to the first driving position so that the washing bin cover 270 moves to the closed position shown in FIG. description of. This moment, the cooking cavity between the pot cover 4 and the pot body 2 is closed. When cooking, closing the washing material compartment cover 270 can prevent the heat from being taken away by a large amount of steam, and can quickly heat up the cooking cavity in the early stage; and when the water boils, avoid foam overflowing into the material washing cavity 211, so that after cooking, washing Stains such as starch remain in the material cavity 211, which affects the user experience. Then, it is also possible to perform the action of exhausting or resetting after cooking. The cooking appliance can be switched from the state shown in FIG. 34 to the state shown in FIG. 32 , that is, the feeding bin 110 and the transmission assembly 300 are moved upward to the initial position. During this process, the force relationship of the washing bin cover 270 is FKG1+G2, so that The washing bin cover 270 is unbalanced in force and cannot remain in the closed position, so it moves downwards to the open position. That is, the resetting of the feeding bin 110, the transmission assembly 300 and the washing bin cover 270 is completed. Since the discharge port 212 is opened, the washing cavity 211 can be used as a steam channel during cooking. Thus, a separate steam valve can be eliminated, which is beneficial to simplify the structure of the pot cover 4, facilitate production and manufacture, and facilitate product miniaturization. Another solution is to perform a reset action directly, that is, to switch the cooking appliance from the state shown in FIG. 39 to the state shown in FIG. 32 . The feeding bin 110 and the transmission assembly 300 move upward to reset. Fifth Embodiment Hereinafter, a cooking appliance according to a fifth embodiment will be described with reference to FIGS. 40 to 46 . The cooking appliance of the fifth embodiment has the same structure and/or structure as the cooking appliance 1 of the first embodiment, except that the washing bin cover 270 is set to be in an open position in an initial state. Therefore, elements having substantially the same functions as those in the first embodiment will be numbered the same here, and will not be described and/or illustrated in detail for the sake of brevity. In this embodiment, as shown in FIG. 40, the discharge port 212 is normally open. Furthermore, the present embodiment does not provide a holding member and a holding fitting member, thus, the washing bin cover 270 is in an open position in an initial state. The control method of this embodiment is roughly the same as the control method of the first embodiment, the main difference is:

S5 Executing the switching between the first driving position and the second driving position of the blanking transmission assembly 300 includes the following methods: The control transmission assembly 300 moves upward from the first driving position to the second driving position to reduce the first magnetic force, so that the washing bin cover 270 moves downward from the closed position to the open position due to gravity. With this control, the transmission assembly 300 can be directly switched from the washing station to the blanking operation, and at the same time, the opening of the discharge port can be realized. This switching method requires less operation and can improve work efficiency.

S6 Execute reset. The washing bin cover 270 of this embodiment is in the open position in the initial state. When it is reset directly after blanking or after cooking, if the washing bin cover 270 is currently in the open position, the process of performing reset No action is performed on the washing bin cover 270 in the middle. If the material washing bin cover 270 is currently in the closed position, then the washing material bin cover 270 needs to be reset. Performing the reset includes: controlling the transmission assembly 300 to move upward from the first driving position, for example, directly moving upward to the storage position, and the washing bin cover 270 is moved from the closed position to the open position by gravity to realize the reset of the washing bin cover 270 . Furthermore, when the feeding bin 110 is controlled to drive the transmission assembly 300 to reset together, the washing bin cover 270 is also reset at the same time. Other steps are substantially the same as the control steps of the first embodiment, and are briefly described for brevity. The entire washing process of the cooking appliance 1 in this embodiment will be described below with reference to FIGS. 40-46 : As shown in FIG. 40 , the cooking appliance 1 is in an initial state. At this time, both the feeding bin 110 and the transmission assembly 300 are in the initial position in the first position, the outlet of the feeding bin 110 and the storage bin 13 and the inlet 201 of the washing bin assembly 200 are not connected, and the washing bin cover 270 is in the Open location. In the initial state, the force relationship of the washing bin cover 270 is FKG1+G2, where F1 is the magnetic force between the translation fitting 231 and the translation driving part 321; G1 is the washing bin cover 270 and its The total weight of the moving follower load, in this embodiment, the follower load includes at least the first mounting seat 220, the translation fitting 231 and the stirring member 19; G2 is the weight of water and materials in the washing chamber 211. It can be understood that G1 is a fixed value, and F1 and G2 are variable values. In this state, the minimum of F1 is Fmin, which may even be close to or equal to 0, G2=0, or G2 is the weight of a small amount of residual water in the washing chamber 211 after cleaning. When the unloading operation is intended, firstly, the linear drive device 120 can drive the screw 121 to move, so that the screw 121 can drive the feeding bin 110 to move downward to the first driving position in the second position, and the transmission assembly 300 also moves downward accordingly. To the first driving position in the second position, as shown in FIG. 41, the cooking utensil is in the first ready state for feeding. At this time, the outlet of the feeding bin 110 and the storage bin 13 and the inlet port 201 of the washing bin assembly 200 are still not connected. During this process, F1 increases; in the state shown in FIG. 41, the washing bin cover The force relationship of 270 is F1>G1+G2, where G2 is the same as the initial state same. Since F1>G1+G2, the force on the washing bin cover 270 is unbalanced, and it cannot be kept in the open position and moved upward to the closed position by the magnetic force. As shown in Figure 42, the washing bin cover 270 has been in the closed position, and the discharge port 212 has been closed. The cooking appliance quickly switches from the state shown in Figure 41 to the state shown in Figure 42, that is, the washing bin cover 270 moves upward to the closed position, and F1 continues to increase to Flmax during this process, and the force relationship is F1>G1+G2 . Where F1 is Flmax, and G2 is the same as the initial state. It can be understood that water can also be supplied to the washing chamber 211 in the state shown in FIG. 42 , that is, water can be supplied to the washing chamber before loading materials. The clean water in the clean water tank 81 enters the feeding bin 110 through the pipeline and the water inlet 113, and then enters the washing chamber 211 through the water outlet 114. When the water supply is selected in the state shown in Figure 42 and the water supply is completed, the force relationship of the washing bin cover 270 is FDG1+G2, wherein F1 is Flmax, and G2 is the weight of water. Then the feeding bin 110 continues to move downwards into the washing chamber 211 without the transmission assembly 300 moving accordingly. At this time, as shown in Figure 43, the feeding bin 110 is in the additional position, the transmission assembly 300 is in the first driving position in the second position, the outlet of the feeding bin 110 and the storage bin 13 and the feeding of the washing bin assembly 200 Ports 201 are all connected, and the washing bin cover 270 is still in the closed position. The material in the storage bin 13 enters the feeding bin 110 through the material inlet 111 , and then enters the washing chamber 211 through the material outlet 112 to perform the unloading action. That is, in this state, solid materials such as rice, millet, corn kernels, black beans, red beans, and mung beans can be transported to the washing chamber 211 through the feeding bin 110. The amount of material flowing into the washing chamber 211 can be calculated by time, and the cooking appliance controls the time when the feeding bin 110 is in the additional position according to the amount of material required by the user, so as to realize quantitative feeding. It is also possible to choose to supply water to the washing chamber 211 in the state of material unloading, or to simultaneously unload the material and supply water, or to wait until the material unloading is completed before performing the water supply action. The clean water in the clean water tank 81 enters the feeding bin 110 through the pipeline and the water inlet 113, and then enters the washing chamber 211 through the water outlet 114. When the feeding and water supply are completed, the stress relationship of the washing bin cover 270 is F1>G1+G2, wherein F1 is Flmax, and G2 is the weight of water and materials. It can be understood that it is also possible not to supply water in the state of Figure 42 and Figure 43, that is, only the material is placed in the state of Figure 43, and the water supply action is performed in the subsequent state, such as in the state of Figure 44. And in the state of Figure 43, water is not supplied, then G2 in the state of Figure 42 is the same as the initial state, and G2 in the state of Figure 43 is the initial state plus the weight of the material. When the blanking is completed or the blanking and water supply are completed, the linear drive device 120 drives the screw 121 again, and the screw 121 drives the feeding bin 110 to move upward to the first driving position in the second position, as shown in FIG. 44 , understandably , you can choose not to supply water in the states shown in Figure 42 and Figure 43, and in Figure 44 Water supply in the state, for example, choose to supply water before the rotation action in Figure 44, or even supply water in the middle of the rotation action. In the state shown in FIG. 44 , the rotation driving device 301 drives the transmission main body 310 to rotate, and then the magnetic force between the rotation driving part 322 and the rotation matching part 232 can drive the second mounting base 250 to rotate, and then drive the first mounting base 220 and The agitator 19 on it rotates together to perform washing action. It can be understood that, for the illustrated embodiment, the water level in the washing chamber 211 is lower than the highest part of the sewage pipe 10 during washing. In other embodiments not shown, a separate electromagnetic valve for opening and closing the sewage outlet 213 can be set, and whether to drain water can be directly controlled by directly controlling the opening and closing state of the electromagnetic valve. The water level in the material chamber 211 must be lower than the highest part of the sewage pipe. For the illustrated embodiment, when the washing action is completed and the water is intended to be drained, water is first supplied to the washing chamber 211 until the water level in the washing chamber 211 is higher than the highest part of the sewage pipe 10, and the siphon principle is used for drainage. And the highest position of the drainage channel will have a velocity head, thereby forming a full flow of the sewage pipe 10 . When the water level dropped to the highest position lower than the sewage pipe 10, since the drainage passage here was in a full flow state, at this moment, the water level in the washing chamber 211 was higher than the water level of the water outlet 114 of the sewage pipe 107. According to Nut's principle, the outlet of the sewage pipe 107 will have a velocity head at this time, which can drain the water in the washing bin. Drainage after washing. When the drainage is completed, the force relationship of the washing bin cover 270 is F1>G1+G2, where F1 is Flmax, and G2 is the weight of the material after water absorption and a small amount of residual water. If necessary, clean water can also be added into the material washing cavity 211 after draining for cooking; in this case, G2 is the weight of the material and the clean water after absorbing water. The actions of water supply, washing and draining can be performed repeatedly to realize multiple washings of a single material. When the drainage action is completed and material is to be dropped, the linear driving device 120 drives the feeding bin 110 to move upward to the second driving position of the second position, as shown in FIG. 45 . In the state shown in Figure 45, the force relationship of the washing bin cover 270 is FKG1+G2, where F1 decreases, that is, FKFlmax, G2 is the same as when the drainage is completed, if clear water is added after the drainage in the state of Figure 44 G2 also includes the weight of fresh water added. Since F1<G1+G2, the load on the washing bin cover 270 is unbalanced and cannot be kept in the closed position and will move downward. The cooking appliance switches from the state shown in FIG. 45 to the state shown in FIG. 46 very quickly. As shown in FIG. 46, the washing bin cover 270 has been positioned at the open position, and the discharge port 212 has been opened. At this time, part of the material or part of the material and water will fall into the inner pot 3, and G2 will decrease. In the state shown in FIG. 46, the stress relationship of the washing bin cover 270 is FKG1+G2, wherein FKFlmax, G2 is the weight of the remaining water-absorbing materials and a small amount of residual water. At this time, the rotating drive device 301 can drive the transmission main body 310 to rotate again, so that the stirring member 19 rotates and starts to throw the material, and the material falls rapidly under the action of centrifugal force. Put into the inner pot3. G2 continues to decrease during material rejection. After the material removal is completed, the force relationship of the washing bin cover 270 is F1 91+G2, where FKFlmax.G2 is the weight of a small amount of residual water. As an example, the difference between F1 and G1+G2 at this time may be 30g. In addition to adding clean water after draining in Figure 44, you can also choose to add clean water in the state shown in Figure 46. For example, you can add clean water before or after the material is thrown, or even in the middle of the material, and you can set it flexibly according to your needs. After the clean water is added into the washing cavity 211, it is then input into the inner pot 3 through the discharge port 212 for subsequent cooking. Various actions in the process of material blanking to blanking can be repeatedly performed to realize multiple times of material washing; that is, each state shown in Figure 41 to Figure 46 is repeatedly performed. That is, after the state in FIG. 46 , the linear drive device 120 drives the feeding bin 110 to move upward to the first driving position of the second position, that is, to reach the position shown in FIG. 41 . Afterwards, the states described in Fig. 41 to Fig. 46 are repeated until the washing and unloading of the materials are completed. Then, after finishing blanking and adding water, the following actions can be performed. One solution is to close the washing bin cover 270 first. That is, the cooking appliance is switched from the state shown in FIG. 46 to the state shown in FIG. 42 . The feeding bin 110 and the transmission assembly 300 are moved to the first driving position to move the washing bin cover 270 to the closed position shown in FIG. 42. During this process, the force relationship of the washing bin cover 270 is FDG1+G2 Wherein F1 is Flmax, G2 is the weight of a small amount of residual water, so that the force of the washing bin cover 270 is unbalanced and cannot be kept in the open position, so it moves upward to the closed position. At this time, the steam inlet 202 is closed, and the pot cover 4 and the The cooking chamber between the pots 2 is closed. When cooking, closing the material washing compartment cover 270 can prevent the heat from being taken away by the steam through the steam inlet 202, which can quickly heat up the cooking cavity in the early stage and speed up the cooking speed. It can be understood that the exhaust action can also be selected during cooking, that is, the cooking utensil can be switched from the state shown in FIG. 42 to the state shown in FIG. 40 or FIG. , during this process, the force relationship of the washing bin cover 270 is FKG1+G2, so that the washing bin cover 270 is unbalanced in force and cannot be kept at the closed position, so it moves downward to the open position. Thus, the separate steam valve can be eliminated, which is beneficial to simplify the structure of the pot cover 4, facilitate production and manufacture, and facilitate product miniaturization. After the exhaust action is completed, the washing bin 270 can be closed, that is, switched to the state shown in FIG. 42 , or the washing bin 270 can not be closed, and remain in the state shown in FIG. 40 or FIG. 46 . Finally, after the cooking is completed, the cooking utensil will remain in the state shown in Figure 40 or switch to the state shown in Figure 40, that is, the positions of the feeding bin 110 and the transmission assembly 300 will be kept or moved to the initial position, so that the washing bin cover 270 is in the normally open position . It can be understood that it is also possible to not exhaust the gas during cooking, and only perform the action of resetting after the cooking is completed. After cooking, the state of the cooking utensil is switched to the state shown in FIG. 40, that is, the feeding bin 110 and the transmission assembly 300 are moved upward to the initial position. During this process, the force relationship of the washing bin cover 270 is FKG1+G2, so that the washing bin cover 270 is unbalanced in force and cannot be kept at the closed position, so it moves downward to the open position. That is, the resetting of the feeding bin 110, the transmission assembly 300 and the washing bin cover 270 is completed. This solution can ensure the heat preservation effect in the cooking chamber, and can prevent foam from overflowing into the washing chamber 211 when the water boils, so that after cooking, starch and other stains remain in the washing chamber 211, affecting user experience. Another solution is to perform a reset action directly after the state shown in FIG. 46, that is, to switch the cooking utensil from the state shown in FIG. 46 to the state shown in FIG. . Since the discharge port 212 is opened, the washing cavity 211 can be used as a steam channel during cooking. Thus, the separate steam valve can be eliminated, which is beneficial to simplify the structure of the pot cover 4, facilitate production and manufacture, and facilitate product miniaturization. It can be understood that during the cooking process, the discharge port 212 can also be closed at any time as required. When the discharge port 212 needs to be closed, as long as the feeding bin 110 and the transmission assembly are moved downward to the position shown in FIG. 41, the washing bin cover 270 Then move upwards and close the discharge port 212 thereupon. It can be understood that the discharge port 212 can also be opened as required after the discharge port is closed during the cooking process. When the discharge port 212 needs to be opened, only the feeding bin 110 and the transmission assembly are moved upward to the position shown in FIG. 45 , or moved upward When the position shown in FIG. 40 is reached, the material washing bin cover 270 can move down and close the discharge port 212 . Finally, after the cooking is completed, the cooking appliance will remain in the state shown in Figure 40 or switch to the state shown in Figure 40, that is, the position of the feeding bin 110 and the transmission assembly 300 will be kept or moved to the initial position, so that the washing bin cover 270 is in the normally open position . In addition, in an embodiment not shown, a water supply pipe communicated with the washing chamber 211 may be provided separately, so as to directly supply water to the washing chamber 211. Thus, water can be supplied to the washing chamber 211 at any stage in the whole washing work. A feeding device that can communicate with the washing chamber 211 can be provided, and the feeding device can not move relative to the storage bin 13 , and a feeding member such as a rotating screw is arranged in the feeding device to supply materials to the washing chamber 211 . It should be noted that the force relationship mentioned in this article can be understood as the force relationship of the components composed of the washing bin cover 270 and the follower load that moves along a straight line with it. For the sake of brevity, it is simply referred to as the washing bin cover 270; similarly, the description of the magnetic force, force, magnetic force, gravity and other forces used in this article to describe the washing bin cover 270 can be understood as the washing bin cover 270 and its linear movement. Various descriptions of the force of the components constituted by the dynamic load, for the sake of brevity, simply use the washing bin cover 270 Instead, as an example, the fact that the washing bin cover 270 is subjected to a magnetic force is understood to mean that the assembly constituted by the washing bin cover 270 and the follower load that moves linearly therewith is subject to a magnetic force.
