In order to realize the washing of materials, a stirring member is arranged. The stirring member is arranged in the washing material bin, and a driving device such as a motor is connected with the stirring member through a mechanical connection structure such as a shaft and a coupling, and drives the stirring member to rotate around the shaft. In order to realize the opening and closing of the discharge port, the mechanical connection structure such as the shaft and the coupling is connected with the washing material bin cover to drive the washing material bin cover to move up and down and keep the washing material bin cover in the closed position.

[0003] In the existing cooking appliance, some of them arrange the washing material bin in the frame. This scheme has a large overall height of the cooking appliance, and it is difficult to take the washing material bin and the pot.

[0004] Therefore, a control method of a cooking appliance and a cooking appliance are needed to at least partially solve the above problems. SUMMARY

[0005] A series of simplified concepts are introduced in the summary section, which will be further described in detail in the detailed description section. The summary section of the present application does not mean to try to limit the key features and necessary technical features of the claimed technical solution, nor to try to determine the protection scope of the claimed technical solution.

[0007] The control method comprises preparing to rotate and drop materials, and the preparing to rotate and drop materials comprises:

[0008] controlling the transmission assembly to move upwardly from a first driving position by a first distance L1 to a non-driving position to reduce the first magnetic force, so that the washing material bin cover moves downwardly from the closed position to the open position due to gravity; and

[0009] controlling the transmission assembly to move downwardly from the non-driving position by a second distance L2 to a second driving position, and the material washing bin cover remains in the open position, wherein the first distance L1 is greater than the second distance L2.

[0010] According to the present scheme, the switching between the two driving positions is achieved by adjusting the up-and-down position of the transmission assembly only, which is easy to operate. The transmission assembly is first moved upwardly by a first distance L1 to move the material washing bin cover from the closed position closing the discharge opening to the open position opening the discharge opening, and then the transmission assembly is moved downwardly by a second distance L2, so as to keep the material washing bin cover in the open position while switching the transmission assembly from the material washing station to the material dropping station (i.e. the second driving position).

[0014] Optionally, in the step of performing the rotating and discharging, the transmission assembly and the stirring member mounting seat are in a second magnetic force in the second driving position, and the transmission assembly drives the stirring member mounting seat to rotate the stirring member through the second magnetic force. In this way, the stirring member can be driven by the magnetic force to realize the material throwing action during the discharging.

[0016] Optionally, in the step of performing the washing, the transmission assembly and the stirring member mounting seat are in a second magnetic force in the first driving position, and the transmission assembly drives the stirring member mounting seat to rotate the stirring member through the second magnetic force. In this way, the stirring member can be driven by the magnetic force to realize the material throwing action during the washing.

[0017] Optionally, after the step of performing the washing, the method further comprises performing the draining: draining the sewage in the material washing cavity.

It can be understood that in other implementations not shown, the heating device can also be configured in other structures, such as electric heating wire heating, etc. Exemplary, the power supply module can be a plug compatible with an external power source, which can supply power to the heating device after being plugged in. The power supply module can also be configured as a battery contained in the base 12, and the power supply module can also be an electric connection line electrically connected to the remaining power supply module on the body assembly 11.

[0073] With reference to Figures 2-9 The body assembly 11 is further provided with a storage mechanism and a feeding mechanism 100. The storage mechanism comprises a storage bin 13, in which solid materials such as rice, millet, corn, black beans, red beans, and green beans can be stored. The storage bin 13 has a lateral outlet, that is, the outlet is provided on the side of the storage bin 13, so as to facilitate the materials in the storage bin 13 to flow out through the outlet. In the illustrated implementation, the outlet is provided at the lower part of the storage bin 13, so as to further facilitate the materials in the storage bin 13 to flow out from the outlet by gravity. The top of the storage bin 13 can be coverably provided with a storage bin cover. The storage bin cover can be opened to add materials into the storage bin.

[0074] With reference to Figures 2-9 and Figure 12The feeding mechanism 100 comprises a feeding bin 110. The feeding bin 110 has an inlet 111, an outlet 112 disposed below the inlet 111, and a feeding passage extending in a vertical direction between the inlet 111 and the outlet 112. The feeding passage is used to transport the solid material. The inlet 111 and the outlet 112 are both disposed on a side wall of the feeding bin 110. The feeding bin 110 further has a water inlet 113, a water outlet 114 disposed below the water inlet 113, and a water passage extending in a vertical direction between the water inlet 113 and the water outlet 114. The water inlet 113 is disposed on the side wall of the feeding bin 110, and the outlet 112 is disposed on the bottom of the feeding bin 110. The feeding bin 110 is movable between at least a first position (e.g., an initial state as shown in Figure 2 ) and a second position (e.g., a state ready for discharging as shown in Figure 3 ). When the feeding bin 110 is in the first position, the side wall of the feeding bin 110 blocks the outlet of the storage bin 13, and the feeding passage of the feeding bin 110 is not in communication with the outlet and the inlet 201 (described below) of the washing bin assembly 200.

[0075] As shown in Figure 4 , the feeding bin 110 further has an additional position, when the feeding bin is in the additional position, the inlet 111 of the feeding bin 110 is in communication with the outlet of the storage bin 13, the solid material enters the feeding passage of the feeding bin and is discharged through the outlet 112 and enters the inlet 201 of the washing bin assembly 200. The feeding bin 110 is generally configured as a columnar structure, and the inlet 111 is an arc-shaped opening extending in the circumferential direction of the feeding bin 110. The feeding bin 110 is movable between the second position (e.g., a state ready for discharging as shown in Figure 3 ) and the additional position (e.g., a discharging state as shown in Figure 4 ). When the feeding bin 110 is in the second position (e.g., a state ready for discharging as shown in Figure 3 ), the side wall of the feeding bin 110 blocks the outlet of the storage bin 13, and the feeding bin 110 is moved downward, the feeding bin 110 and the outlet of the storage bin 13 are switched from a closed state to a communication state, i.e., the inlet 111 of the feeding bin 110 is opened, at the same time, the outlet 112 of the feeding bin 110 is also opened, therefore, the material in the storage bin 13 can be fed from the side of the feeding bin 110, flow through the feeding passage, and be discharged from the side into the washing bin assembly 200.

[0076] Wash bin assembly

[0077] As shown in Figures 2-9 and Figures 13-16As shown, the cooking appliance 1 further comprises a washing bin assembly 200, which is arranged in the lid 4.

The washing bin body 210 further has a material inlet 201 via which the material in the material feeding bin 110 described above can enter the washing bin cavity 211. The material inlet 201 is located above the discharge opening 212. Further, the washing bin body 210 forms the washing bin cavity 211 having the material inlet 201 and the discharge opening 212.

[0078] The washing bin assembly 200 comprises a side wall portion 6. The side wall portion 6 is arranged on the lid 4 and forms the washing bin body 210, the side wall portion 6 enclosing the washing bin cavity 211 having the discharge opening 212. In a preferred embodiment, the side wall portion 6 is formed as a part of the lid 4, that is, the side wall portion 6 is integrally formed with the lid 4. The side wall portion 6 can be arranged to extend vertically, that is, to have the same width from top to bottom, or to extend obliquely from top to bottom towards the inside of the washing bin cavity 211, that is, to have a larger width at the bottom and a smaller width at the top, so as to reduce material residue. In addition, the inner surface of the side wall portion 6 is arranged as a smooth surface to further reduce material residue. The washing bin assembly 200 further comprises a stirring member 19 arranged in the washing bin cavity and a washing bin cover 270 arranged below the stirring member 19. The washing bin cover 270 and part of the first mounting seat 220 (described below), the stirring member 19, and a material opening seal 261 (described below) together cover the discharge opening 212.

[0079] In other embodiments, the washing bin cover 270 can cover the discharge opening 212 alone, that is, the discharge opening 212 can be completely closed by the washing bin cover 270 alone.

[0080] The washing bin cover 270 is movably arranged in the washing bin body 210, in particular, the washing bin cover 270 is movable between an open position in which the discharge opening 212 is open and a closed position in which the discharge opening 212 is covered. Figures 2-6 As shown, the washing bin cover 270 is located above, in the closed position in which the discharge opening 212 is covered. Figures 7-9 As shown, the washing bin cover 270 is moved to below, in the open position in which the discharge opening 212 is open, at this time the material in the washing bin cavity 211 can fall into the inner pot 3 via the discharge opening 212.

[0081] In the illustrated embodiment, the stirring member is fixed and supported on the first mount, the material washing bin cover 270 is in contact with the stirring member 19 and the first mount 220 at both ends and the axial freedom of both ends is simultaneously constrained by the stirring member 19 and the first mount 220, and the stirring member 19 can move together with the material washing bin cover 270 between the open position and the closed position. The stirring member 19 can be rotatable relative to the material washing bin cover 270. In other embodiments not shown, the stirring member 19 can also be fixedly connected to the material washing bin cover 270, i.e., the material washing bin cover 270 can rotate together with the stirring member 19. That is, the material washing bin cover 270 can rotate or not rotate when the stirring member 19 rotates.

[0082] In one embodiment, the stirring member 19 can rotate during the material washing and material spinning operations. Preferably, the stirring member 19 is configured in the shape of a rotating disc and is provided with a tapered guide surface that is inclined in the axial direction and inclined outwardly along the radial direction of the stirring member 19 from top to bottom. This arrangement enables the material on the stirring member 19 to be more easily spun out during rotation in addition to the action of the centrifugal force, and the inclined guide surface also facilitates the downward sliding of the material, which can reduce the residual material in the material washing cavity 211.

[0083] Drive assembly

[0084] In one embodiment, the cooking appliance 1 further comprises a transmission assembly 300 that is linearly movable. Specifically, the transmission assembly 300 can be engageable with the material feeding bin 110 to move the transmission assembly 300 together with the material feeding bin 110 between the first position (as shown in FIG. 1) and the second position (as shown in FIG. 2). The transmission assembly 300 can drive at least a part of the material washing bin assembly 200 to rotate, for example, at least the stirring member 19, to complete the processes of material washing and / or material spinning during material dropping; and can drive the stirring member 19 together with the material washing bin cover 270 to move between the open position and the closed position to complete the processes of material dropping and water draining. Figure 2 Figure 3 The transmission assembly 300 is arranged in the material storage mechanism or the material feeding mechanism 100. In particular, the transmission assembly 300 is not arranged on the pot cover 4. This arrangement can reduce the components on the pot cover 4, simplify the structure of the pot cover, facilitate the cleaning operation of the pot cover 4 and the material washing bin assembly 200 by the user, and simplify the manufacturing process by not needing to consider the waterproofing of the transmission assembly 300 during the manufacturing stage of the pot cover 4.

[0085] The above-mentioned material storage mechanism, material feeding mechanism 100, transmission assembly 300 and material washing bin assembly 200 constitute part of the material washing system of the present embodiment.

[0086] The above-mentioned material storage mechanism, material feeding mechanism 100, transmission assembly 300 and material washing bin assembly 200 constitute part of the material washing system of the present embodiment.​

[0087] The transmission structure between the feeding mechanism 100, the transmission assembly 300, and the washing bin assembly 200 is described in detail below with reference to the accompanying drawings.

[0088] The feeding mechanism 100 can be connected to the transmission assembly 300 via contact transmission. The transmission assembly 300 can be connected to the washing chamber assembly 200 via magnetic force generated by a magnetic component, enabling a contactless transmission between the transmission assembly 300 and the washing chamber assembly 200. In this embodiment, the washing chamber cover 270 can be in a closed or open position initially. In other words, when the cooking appliance 1 is not in operation, the discharge port 212 can be in a normally closed or normally open state.

[0089] The illustrated embodiment shows one implementation of the transmission structure between the feeding mechanism 100, the transmission assembly 300, and the washing bin assembly 200. The discharge port 212 is schematically shown to be in a normally closed state.

[0090] As described above, the feeding bin 110 can move linearly between a first position and a second position together with the transmission assembly 300. Figure 4 As shown, the feeding bin 110 also has an additional position. In the additional position, the feeding bin 110 is closer to the washing chamber 211. The feeding bin 110 has a feed channel for conveying solid materials, which is not in communication with either the storage bin 13 or the washing chamber 211 in the first and second positions. When the feeding bin 110 moves to the additional position, the transmission assembly 300 does not move accordingly. Thus, in the additional position, the feeding bin 110 can extend relative to the transmission assembly 300 and into the washing chamber 211, at which time the feed channel of the feeding bin 110 can communicate with both the storage bin 13 and the washing chamber 211. In this embodiment, the feeding bin 110 has a two-stage movement relative to the transmission assembly 300. In one stage of movement, i.e., when moving from the first position to the second position and when returning from the second position to the first position, the feeding bin 110 moves together with the transmission assembly 300. In the other stage of movement, i.e., when moving from the second position to the additional position and when moving from the additional position to the second position, the feeding bin 110 moves separately from the transmission assembly 300. The feeding bin 110 can move from the second position to the additional position and from the additional position to the second position, allowing the feeding bin 110 to enter or leave the washing chamber 211, facilitating material feeding and stopping.

[0091] The washing hopper assembly 200 is located below the transmission assembly 300. When the feeding hopper 110 is in the additional position, the transmission assembly 300 can abut against the top surface of the washing hopper body 210, so that the transmission assembly 300 can stop moving when the feeding hopper 110 moves from the second position to the additional position. In other embodiments not shown, a separate fixed support frame is included, which abuts the transmission assembly 300 when the feeding hopper 110 is in the additional position. This fixed support frame can be a separate support frame directly fixed to the pot lid 4.

[0092] like Figures 10-12 As shown, the feeding mechanism 100 may further include a linkage 130. The linkage 130 is disposed at the bottom of the feeding bin 110. For example, a rotary connection structure 117 is provided on the bottom surface of the feeding bin 110, and the linkage 130 is provided with a structure that cooperates with the rotary connection structure 117. Rotating the linkage 130 connects it to the rotary connection structure 117. The linkage 130 is then fixed to the rotary connection structure 117 with screws. The transmission body 310 is provided with a central hole 313, which is located at the center of the transmission body 310. The feeding bin 110 is located within the central hole 313.

[0093] The linkage 130 is located on the lower side of the transmission body 310 and has an upward-facing linkage support surface 131 for supporting the transmission assembly 300 upwards. With the aid of the linkage support surface 131, the feeding bin 110 can drive the transmission assembly 300 to move upwards. In the illustrated embodiment, the transmission assembly 300 can move downwards along with the feeding bin 110 due to its own weight. The linkage support surface 131 can be constructed as an inclined surface in the vertical direction. The illustrated embodiment shows the linkage support surface 131 as an annular conical surface, specifically inclined outwards from top to bottom along the radial direction of the linkage 130. This guides the feeding bin 110 and the transmission assembly 300 as they move from a separated state to a connected state, resulting in better cooperation.

[0094] The feeding mechanism 100 also includes a linear drive device 120. The linear drive device 120 is connected to the feeding bin 110 and drives the feeding bin 110 to move linearly. Specifically, the feeding bin 110 is provided with a vertically extending screw hole 115, and the feeding mechanism 100 also includes a screw 121. The screw 121 is connected to the output shaft of the linear drive device 120 and is located within the screw hole 115. When the output shaft rotates, the screw 121 can move relative to the feeding bin 110 within the screw hole 115, thereby causing the feeding bin 110 to move up and down.

[0095] The feeding mechanism 100 further comprises a fixed bracket 122, a fixed seat 123 and a fixed pressing plate 124. The fixed bracket 122 is located in the storage bin 13 and can be connected to the storage bin 13. For example, the inner bottom surface of the storage bin 13 can be provided with upwardly extending studs (not shown), and the fixed bracket 122 can be provided with screw platforms 126 with through holes at intervals, and the screws can be locked to the studs through the through holes, so that the fixed bracket 122 can be installed to the storage bin 13. The fixed bracket 122 can be provided with a receiving cavity with an opening downward, and the linear driving device 120 is connected to the fixed bracket 122 and located in the receiving cavity. Specifically, the linear driving device 120 is located in the concave cavity of the fixed seat 123, and the fixed seat 123 is accommodated in the receiving cavity. The concave cavity is matched with the shape of the linear driving device 120 to limit the rotation and vertical movement of the linear driving device 120. The fixed pressing plate 124 is located on the side, i.e. the lower side, of the linear driving device 120 opposite to the fixed seat 123. The fixed pressing plate 124 can be connected with the fixed seat 123, for example, the fixed pressing plate 124 and the fixed seat 123 are both provided with screw holes, and the fixed bracket 122 is provided with downwardly extending screw studs 127, and the screws are locked to the screw studs 127 through the screw holes of the fixed pressing plate 124 and the fixed seat 123. The end of the screw rod 121 is clamped between the fixed pressing plate 124 and the fixed seat 123.

[0096] The bottom of the fixed bracket 122 and the inner bottom surface of the storage bin 13 can form an outlet of the storage bin 13. The outlet is located on one side of the fixed bracket 122. The fixed bracket 122 is provided with an outlet sealing piece 125 on the side corresponding to the outlet. The outlet sealing piece 125 can abut against the side wall of the feeding bin 110 to prevent the material from entering the feeding mechanism 100. The fixed bracket 122 is further provided with guide columns 128 extending vertically at intervals. The top of the feeding bin 110 is provided with guide protrusions 116 at intervals, and the guide protrusions 116 protrude from the side wall of the feeding bin 110. The guide protrusions 116 are located between the guide columns 128 arranged at intervals and are movable along the guide columns 128 to prevent the feeding bin 110 from shifting during movement.

[0097] The washing hopper assembly 200 also includes a washing hopper mating part 230 and a mounting base 240. The washing hopper mating part 230 can be connected to the mounting base 240. Part or all of the mounting base 240 can be movably disposed in a straight line on the washing hopper body 210. In the illustrated embodiment, part of the mounting base 240 is movable in a straight line. The agitator 19 is located in the washing chamber 211 and connected to the mounting base 240. The agitator 19 is rotatable with the mounting base 240 relative to the washing hopper body 210 about a first rotation axis Ax1. The washing hopper cover 270 can be disposed on the mounting base 240 and is movable in a straight line with the mounting base 240. The mounting base 240 is rotatable with respect to the washing hopper body 210 about the first rotation axis Ax1. The transmission assembly 300 includes a transmission body 310 and a washing hopper drive 320. The transmission body 310 is rotatable with respect to the washing hopper body 210 about a second rotation axis Ax2. The transmission body 310 is engageable with and rotatable relative to the feeding bin 110. The washing bin drive 320 is disposed on the transmission body 310 and can be installed to the transmission body 310, for example, by means of screw connection.

[0098] There may be a magnetic force between the washing hopper mating part 230 and the washing hopper drive part 320. When the transmission body rotates, the mounting base 240 and the stirring part 19 thereon rotate under the action of the magnetic force; and when the magnetic force between the washing hopper mating part 230 and the washing hopper drive part 320 is changed, the mounting base 240 moves in a straight line to open and close the washing hopper cover 270.

[0099] The transmission body 310 has a non-drive position that disengages the washing bin mating part 230 from the washing bin drive part 320 (e.g., Figure 6 and Figure 7 (The different material feeding states shown) and the driving positions that link the washing bin mating part 230 and the washing bin drive part 320. The driving positions include a first driving position (e.g., Figures 3-5 The states shown) and the second drive position (as shown) Figure 8 The material feeding state is shown. The first drive position corresponds to the closed position, the second drive position corresponds to the open position, and the non-drive position can be the open position (e.g., ...). Figure 6 and Figure 7 The different material feeding states shown can also be in the closed position (e.g., ...). Figure 2 (The initial position), of course, in other embodiments, the initial position can be set to the open position.

[0100] The first position can be a non-driven position, which includes an initial position and an intermediate position (e.g., ...). Figure 6 and Figure 7The second position can be a driving position and include a first driving position and a second driving position. Further, when the transmission body 310 is located at the first position, the material washing bin driving member 320 is disengaged from the material washing bin cooperating member 230. When the transmission body 310 is located at the second position, the material washing bin driving member 320 cooperates with the material washing bin cooperating member 230. The intermediate position is between the initial position and the second driving position. It should be noted that, for the convenience of understanding, Figure 6 and Figure 9 The transition state in the action process is shown, and the mounting seat 240 of the material washing bin cover 270 is in a force imbalance in the transition state.

[0101] The contactless transmission is formed between the material washing bin assembly 200 and the transmission assembly 300. When the material is washed in the material washing cavity 211, the material washing water exists in a space isolated from the transmission assembly 300 and does not contact the transmission assembly 300. Thus, the transmission assembly 300 can be prevented from being contaminated by the material washing water. Compared with the mechanical transmission mode, the contactless transmission mode does not need to clean the transmission structure, which can improve the user experience.

[0102] In the embodiment, the material feeding bin 110 and the transmission assembly 300 can generate a stroke of synchronous movement, and the transmission assembly 300 and the material washing bin cover 270 can generate cooperative movement, so that only one driving device for driving the material feeding bin 110 to move can be provided, and three linear movements of the material feeding bin 110, the transmission assembly 300 and the material washing bin cover 270 can be completed, and the movement of the material feeding bin 110 and the opening and closing action of the discharge port 212 can be realized. And only one driving device for driving the transmission body 310 to rotate can be provided, and the material washing and the material throwing action during the material dropping can be realized.

[0103] The material washing bin cooperating member 230 can include a translational cooperating member 231. The translational cooperating member 231 is arranged on the mounting seat 240. The material washing bin driving member 320 can include a translational driving member 321. The translational driving member is arranged on the transmission body 310. The translational driving member 321 and the translational cooperating member 231 are both magnetic members, and a magnetic force can exist between them. When the state of the translational driving member 321 is changed to change the magnetic force between the translational cooperating member 231 and the translational driving member 321, the material washing bin cover 270 moves between the open position of opening the discharge port 212 and the closed position of closing the discharge port 212. The transmission assembly 300 and the material washing bin cover 270 can realize cooperative movement through the magnetic force. When the transmission body 310 is moved, the material washing bin cover 270 can be opened and / or closed under the action of the magnetic force, and thus the opening and closing action of the discharge port 212 can be realized.

[0104] In one embodiment, the washing bin cover 270 is moved from the open position to the closed position when the state of the translational driving member 321 is changed. Thus, the closing of the washing bin cover 270 can be achieved by means of the magnetic force between the translational engaging member 231 and the translational driving member 321. In another embodiment, the washing bin cover 270 is moved from the closed position to the open position when the state of the translational driving member 321 is changed. Thus, the opening of the washing bin cover 270 can be achieved by means of the magnetic force between the translational engaging member 231 and the translational driving member 321. In the illustrated embodiment, the washing bin cover 270 is moved from the open position to the closed position and from the closed position to the open position when the state of the translational driving member 321 is changed. Thus, the opening and closing of the washing bin cover 270 can be achieved simultaneously by means of the magnetic force between the translational engaging member 231 and the translational driving member 321.

[0105] The washing bin engaging member 230 can comprise a rotating engaging member 232. The washing bin driving member 320 can comprise a rotating driving member 322. The rotating engaging member 232 is arranged on the mounting base 240. The rotating driving member is arranged on the transmission main body 310, and the rotating driving member and the rotating engaging member 232 are magnets. When the transmission main body 310 is rotated, the stirring member 19 is rotated under the action of the magnetic force between the rotating driving member and the rotating engaging member 232. Thus, when the transmission main body 310 is rotated in the case of opening and closing the washing bin cover 270, the actions of washing and discharging can be achieved.

[0106] The magnetic member can comprise at least one of a magnet, an electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel. Alternatively, the magnet can be a permanent magnet. Alternatively, at least one of the translational engaging member 231 and the translational driving member 321 can be a magnet. For example, the translational engaging member 231 is a magnet; the translational driving member 321 is one of a magnet, an electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel. One example is that the translational engaging member 231 and the translational driving member 321 are both magnets, so that a larger magnetic force can exist between the translational engaging member 231 and the translational driving member 321 and the state is stable. Another example is that the translational engaging member 231 is iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel, and the translational driving member 321 is a magnet. Since the magnetism of iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel is not affected by high temperature, the magnetism of the translational engaging member 231 can be prevented from being affected by high temperature during cooking, so that the performance remains unchanged. Alternatively, at least one of the translational engaging member 231 and the translational driving member 321 is an electromagnet.

[0107] When the washing bin cover 270 and the stirring member 19 are arranged in the same mounting seat 240, considering that the rotation of the mounting seat 240 will cause the wire to be wound, the translational matching member 231 and the translational driving member 321 are not selected as electromagnets. When the washing bin cover 270 and the stirring member 19 are arranged in different mounting seats 240, the switch of the washing bin cover 270 and the rotation of the stirring member 19 are independent of each other, and the translational matching member 231 and the translational driving member 321 can be selected as electromagnets.

[0108] For the embodiment not including electromagnets, the transmission assembly 300 is linearly movable relative to the washing bin body 210. When the transmission assembly 300 moves to change the magnetic force between the translational matching member 231 and the translational driving member 321, the washing bin cover 270 moves between the open position of opening the discharge port 212 and the closed position of closing the discharge port 212. For the illustrated embodiment, by controlling the position of the up-and-down movement of the transmission assembly 300, the direction of the movement of the washing bin cover 270 is controlled according to the direction change of the resultant force of the magnetic force and the gravity, so as to move to the open position and the closed position.

[0109] For the embodiment of the electromagnets, when the energization state of the electromagnets is changed, the washing bin cover 270 can be linearly moved to open and close the discharge port 212.

[0110] According to design requirements, the rotational driving member 322 can be located radially outside the rotational matching member 232 when in the driving position. Alternatively, the rotational driving member 322 can be located radially inside the rotational matching member 232 when in the driving position. Alternatively, the rotational driving member 322 can be located above the rotational matching member 232 when in the driving position.

[0111] The washing bin assembly 200 is located below the transmission assembly 300, and the feeding bin 110, the washing bin cover 270 and the transmission assembly 300 are all movable up and down. The translational driving member 321 corresponds to the up-and-down position of the translational matching member 231, and the magnetic poles facing each other are opposite or the same. When the magnetic poles are opposite, the magnetic force between the translational driving member 321 and the translational matching member 231 is magnetic attraction force, and the washing bin cover 270 is moved by the magnetic attraction force; when the magnetic poles are the same, the magnetic force between the translational driving member 321 and the translational matching member 231 is 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 translational driving member 321 and the translational matching member 231 facing each other are opposite, and the magnetic force therebetween is magnetic attraction force.

[0112] As Figure 10As shown, the transmission main body 310 is configured in a disc shape and includes a transmission top wall 311 and a transmission side wall 312 connected to the transmission top wall 311. The transmission side wall 312 extends in a vertical direction, the translational driving member 321 is disposed on the transmission top wall 311, and the rotational driving member 322 is disposed on the transmission side wall 312. The translational driving member 321 is disposed on the transmission main body 310 by at least one of clamping, fastener connection, and in-mold injection. The translational driving member 321 in the illustrated embodiment is detachably mounted to the transmission main body 310 by a fastener such as a screw.

[0113] The height of the transmission main body 310 in the first driving position is lower than the height of the transmission main body 310 in the second driving position. Further, the first driving position is located above the second driving position. When the transmission main body 310 is located in the first driving position, the translational driving member 321 can be linked with the translational cooperating member 231, and the rotational driving member 322 can be linked with the rotational cooperating member 232. When the transmission main body 310 is located in the second driving position, the translational driving member 321 is disengaged from the translational cooperating member 231, and the rotational driving member 322 is linked with the rotational cooperating member 232. For the illustrated embodiment, see Figure 8 When the transmission main body 310 is located in the second driving position, the magnetic force between the translational driving member 321 and the translational cooperating member 231 is smaller than the gravitational force of the washing bin cover 270, the first mounting seat 220 connected to the washing bin cover 270, and the stirring member 19. Thus, the washing bin cover 270 can be kept in the open position.

[0114] In the illustrated embodiment, the washing bin cooperating member 230 can be located outside the washing bin cavity 211, i.e., both the rotational cooperating member 232 and the translational cooperating member 231 are located outside the washing bin cavity 211. When the transmission main body 310 is located in the first driving position and the second driving position, the rotational driving member 322 is located radially outside the rotational cooperating member 232. Thus, the structure inside the washing bin cavity 211 can be simplified, the volume of the washing bin cavity 211 can be increased, the single processing capacity of the washing bin cavity 211 can be improved, and the washing bin cavity 211 can be easily cleaned.

[0115] Reference will be made to Figures 13-17 The structure of the washing bin assembly 200 in the present embodiment is described.

[0116] As Figure 13 and Figure 14As shown, the mounting seat 240 comprises a first mounting seat 220 and a second mounting seat 250 connected to the first mounting seat 220. The first mounting seat 220 is located radially inward of the second mounting seat 250 and is linearly movable relative to the second mounting seat 250. The stirring member 19, the material washing chamber cover 270 and the translational cooperation member 231 can be provided on the first mounting seat 220. The rotational cooperation member 232 can be provided on the second mounting seat 250. The first mounting seat 220 can rotate with the second mounting seat 250. In this embodiment, the first mounting seat 220 is a stirring member mounting seat and also a chamber cover mounting seat, that is, the stirring member mounting seat and the chamber cover mounting seat are formed as an integral piece. In an embodiment not shown, the stirring member mounting seat and the chamber cover mounting seat can be separate components and are independently provided and independently movable, that is, the stirring member does not move linearly together with the material washing chamber cover.

[0117] The first mounting seat 220 can comprise a mounting seat base 221 and a mounting seat cylinder portion 222 connected to the mounting seat base 221. The stirring member 19 and the material washing chamber cover 270 are provided on the mounting seat base 221. The mounting seat cylinder portion 222 is located radially outward of the material washing chamber 211, and a seat opening 224 is provided at the bottom of the mounting seat cylinder portion 222 in a circumferential direction, so that the material falls into the inner pot 3 through the seat opening 224 during material falling. The translational cooperation member 231 is provided at the top of the mounting seat cylinder portion 222, so that there is a small distance between the translational cooperation member 231 and the translational driving member 321, and a large enough magnetic force can be generated to move the material washing chamber cover 270 up and down.

[0118] The translational cooperation member 231 is provided on the mounting seat 240 by at least one of clamping, fastener connection, in-mold injection, etc. Figure 13 As shown, the translational cooperation member 231 can be pre-embedded in the mounting seat cylinder portion 222, for example, formed in the mounting seat cylinder portion 222 by an in-mold injection process. Alternatively, in an embodiment not shown, the translational cooperation member 231 can also be detachably mounted to the mounting seat cylinder portion 222 by a fastener such as a screw, etc. Specifically, the top surface of the mounting seat cylinder portion 222 is provided with a downwardly recessed mounting groove, and the translational cooperation member 231 is fixed in the mounting groove. The translational cooperation member 231 can be provided in a plurality of block-shaped members or one circular ring-shaped member, etc. For the embodiment of a plurality of translational cooperation members 231, the plurality of translational cooperation members 231 can be arranged in a circumferential direction of the first mounting seat 220, and preferably arranged in a ring array.

[0119] The washing hopper assembly 200 also includes a hopper body base 217. The hopper body base 217 is located below the washing hopper body 210 and is detachably connected to the washing hopper body 210 by means such as a fastening connection. A second mounting base 250 is supported on the hopper body base 217 located below it. A rotating mating member 232 can be disposed on the vertically extending outer peripheral surface of the second mounting base 250 so that a small radial distance exists between the rotating mating member 232 and the rotating drive member 322, generating a sufficiently large magnetic force to rotate the mounting base 240. Multiple rotating drive members 322 and rotating mating members 232 can be provided and are block-shaped components. Multiple rotating drive members 322 are arranged circumferentially spaced along the transmission body 310. Multiple rotating mating members 232 are arranged circumferentially spaced along the second mounting base 250.

[0120] When the transmission assembly 300 is in the driving position, the projections of the rotary drive member 322 and the rotary mating member 232 on the plane parallel to the axial direction overlap. When the transmission assembly 300 is in the first driving position, the projections of the rotary drive member 322 and the rotary mating member 232 on the plane parallel to the axial direction have a first overlapping area. When the transmission assembly 300 is in the second driving position, the projections of the rotary drive member 322 and the rotary mating member 232 on the plane parallel to the axial direction have a second overlapping area. The first overlapping area can be larger than the second overlapping area. Multiple rotary drive members 322 and multiple rotary mating members 232 can be arranged in one or two rows axially. For example, in the illustrated embodiment, as shown... Figure 10 and Figure 14 As shown, the rotary drive component 322 and the rotary mating component 232 can both be arranged in a row along the axial direction, and both can be constructed into long strips, i.e., long strip-shaped components. The rotary drive component 322 is placed horizontally, and the rotary mating component 232 is placed vertically.

[0121] The main body 210 of the washing silo may also include a top wall 216, an inner side wall 214 and an outer side wall 215 connected to the top wall 216. Figure 15), and the three constitute the side wall part 6. The inner side wall 214 is located radially inward of the outer side wall 215 and is spaced apart from the outer side wall 215 in the radial direction. The inner side wall 214 encloses the washing material cavity 211. The second mounting seat 250 and the mounting seat cylinder part 222 are located between the inner side wall 214 and the outer side wall 215. One of the first mounting seat 220 and the second mounting seat 250 can be provided with a seat guide groove 223 extending in the axial direction, and the other of the first mounting seat 220 and the second mounting seat 250 can be provided with a seat guide part 251 located within the seat guide groove 223 and movable linearly relative to the seat guide groove 223. By providing the first mounting seat 220 and the second mounting seat 250 with the concave-convex matched guide structures, on the one hand, the first mounting seat 220 can rotate together with the second mounting seat 250, and on the other hand, the first mounting seat 220 can be kept moving linearly and displacement is avoided.

[0122] The washing material bin assembly further comprises a support component. The support component is provided on the washing material bin body 210. The support component is provided with an upward-facing seat limiting surface 252 for upwardly supporting the mounting seat 240. In the embodiment, the support component comprises the second mounting seat 250 and the bin body base 217. The second mounting seat 250 is provided with the upward-facing seat limiting surface 252 for upwardly supporting the first mounting seat 220. The bin body base 217 upwardly supports the first mounting seat 220. Figure 16 It is shown in FIG. 2 that the mounting seat cylinder part 222 is provided with the seat guide groove 223, and the second mounting seat 250 is provided with the seat guide part 251. The top surface of the seat guide part 251 is the seat limiting surface 252. In an embodiment not shown, the second mounting seat 250 is provided with the seat guide groove 223, and the mounting seat cylinder part 222 is provided with the seat guide part 251. The bottom surface of the seat guide groove 223 is the seat limiting surface 252.

[0123] Optionally, the mounting seat cylinder part 222 can comprise a cylinder part upper portion and a cylinder part lower portion. The cylinder part upper portion protrudes radially outward of the cylinder part lower portion, i.e. the thickness of the cylinder part upper portion is greater than the thickness of the cylinder part lower portion. The seat guide groove 223 can be provided on the cylinder part upper portion, and the seat opening 224 can be provided on the cylinder part lower portion.

[0124] As Figure 13 、 Figure 17 and Figure 17AAs shown, to avoid water leakage when the material washing action is performed, the material washing bin assembly 200 further comprises a material port seal 261. The material port seal 261 can be arranged on the outer periphery of the material washing bin cover 270 so as to move up and down together with the material washing bin cover 270. When the material washing bin cover 270 is in the closed position, the material port seal 261 abuts against the material washing bin body 210 at the material discharge port 212. Thus, the material washing bin cover 270 is pressed and does not rotate relative to the first mounting base 220 and the stirring member 19. When the material washing bin cover 270 is in the closed position, the material port seal 261 can seal the gap between the material washing bin cover 270 and the material washing bin body 210, so as to avoid water leakage from the gap when the material is washed. When the material washing bin cover 270 is in the closed position and the stirring member 19 rotates, the material washing bin cover 270 remains stationary relative to the material washing bin body 210, i.e., the relative position between the material washing bin cover 270 and the material washing bin body 210 remains unchanged and the material washing bin cover 270 does not rotate together with the stirring member 19. The sealing effect of the material port seal 261 can be better guaranteed, and the material washing bin cover 270 is more tightly closed, so as to avoid water leakage.

[0125] The material washing bin cover 270 is arranged on the side of the mounting base base portion 221 facing the material washing cavity 211, specifically, the upper side of the mounting base base portion 221. The mounting base base portion 221 can be rotatable relative to the material washing bin cover 270. The outer periphery of the material washing bin cover 270 can be provided with a cover groove 273 recessed radially inward. The cover groove 273 is annular. A portion of the material port seal 261 can be located in the cover groove 273.

[0126] In an embodiment, as shown in the illustrated embodiment, the material port seal 261 can be located below the material washing bin body 210. The material washing bin cover 270 can have a cover support surface 271. The cover support surface 271 faces the side where the material discharge port 212 is located, specifically, faces upward. The material port seal 261 can abut against the cover support surface 271 to provide an upward support force to the material port seal 261. When the material washing bin cover 270 is in the closed position, the material port seal 261 is clamped between the bottom of the material washing bin body 210 and the cover support surface 271, and the material washing bin cover 270 is pressed downward at the cover support surface 271 and remains stationary relative to the material washing bin body 210. In this embodiment, the bottom surface of the side wall portion 6 can abut against the material port seal 261, specifically, the bottom surface of the inner side wall 214 can abut against the material port seal 261. The material port seal 261 is pressed downward. In other embodiments not shown, the inner surface of the side wall portion 6 can abut against the material port seal 261, and the friction between the material port seal 261 and the side wall portion 6 can limit the rotation of the material washing bin cover 270.

[0127] As Figure 17AAs shown, the bottom of the material washing bin body 210 is provided with a body arc surface 218, which can abut against the material port sealing member 261. The contact area between the bottom of the material washing bin body 210 and the material port sealing member 261 is increased, which is beneficial to the abutment between the two being more stable and the sealing effect being better.

[0128] The material port sealing member 261 is an annular member and is sleeved on the outer circumferential portion of the material washing bin cover 270. The outer circumferential portion of the material washing bin cover 270 can be provided with a cover boss 272 protruding radially outward. The material port sealing member 261 is arranged on the cover boss 272. The upper surface of the cover boss 272 is a cover support surface 271, which can support the material washing bin cover 270.

[0129] The mounting seat base 221 can be provided with a cover mounting portion 263, and the material washing bin cover 270 can be provided with a cover mounting hole 264. The cover mounting portion 263 can be located in the cover mounting hole 264. A mounting sealing member 262 is arranged between the hole wall of the cover mounting hole 264 and the cover mounting portion 263 to seal the gap between the mounting seat base 221 and the material washing bin cover 270. The cover mounting portion 263 is provided with a radially recessed mounting portion groove 265, and the mounting sealing member 262 is located in the mounting portion groove 265. An abutment boss is arranged in the cover mounting hole 264, and the abutment boss is provided with a seat arc surface 274 facing the mounting portion groove 265, so as to increase the contact area of the mounting sealing member 262 with the cover mounting hole 264 and improve the sealing effect.

[0130] The stirring member 19 can be located on the side opposite to the mounting seat base 221 of the material washing bin cover 270, specifically, the upper side. That is, the material washing bin cover 270 is located between the stirring member 19 and the mounting seat base 221. The stirring member 19 is connected to the cover mounting portion 263. One of the stirring member 19 and the cover mounting portion 263 can be provided with a connecting protrusion, and the other one can be provided with a connecting groove. The connecting protrusion is located in the connecting groove. Fasteners such as screws can be connected to the connecting protrusion through the mounting seat base 221 to connect the stirring member 19 to the mounting seat base 221. In the figure, the stirring member 19 is shown as being provided with the connecting protrusion, and the cover mounting portion 263 is shown as being provided with the connecting groove.

[0131] As shown in the illustrated embodiment, the material washing bin cover 270, the mounting seat base 221, the stirring member 19 and the material port sealing member 261 are combined together, and when the material washing bin cover 270 is located in the closed position, the material washing bin cover 270, the mounting seat base 221, the stirring member 19 and the material port sealing member 261 together block the material discharging port 212. When the stirring member 19 and the mounting seat base 221 rotate together, neither the material washing bin cover 270 nor the material port sealing member 261 rotates, that is, the relative position of the material washing bin cover 270 with respect to the material washing bin body 210 remains unchanged. The sealing effect of the material port sealing member 261 can be guaranteed to be better, the material washing bin cover 270 is closed more tightly, and the condition of water leakage is avoided.

[0132] Optionally, the discharge port 212 can be closed by other means, such as the material washing cover 270 alone, or the material washing cover 270 together with one or more of the sealing member, the stirring member 19, and the mounting seat. The sealing member, the stirring member 19, and the mounting seat can be synchronously moved together with the material washing cover 270 to open and close the discharge port 212 together. The sealing member, the stirring member 19, and the mounting seat can also be moved separately from the material washing cover 270 to open and close the discharge port 212.

[0133] Optionally, the discharge port 212 can be closed by only the material washing cover 270, which can cover the discharge port 212. Further, a sealing member can be arranged between the material washing cover 270 and the main body of the material washing bin, and the discharge port 212 can be closed by the material washing cover 270 and the sealing member together. The sealing member can be arranged on the material washing cover 270 or the main body of the material washing bin.

[0134] Optionally, the discharge port 212 can be closed by the material washing cover 270 and part of the mounting seat together, and further, a sealing member can be included, and the discharge port 212 can be closed by the material washing cover 270, part of the mounting seat, and the sealing member together. The sealing member can be arranged on one or more of the material washing cover 270, part of the mounting seat, and the main body of the material washing bin to better seal the discharge port 212. It can be understood that this way of closing the discharge port 212 is to open and close part of the discharge port 212 by the material washing cover 270, which also belongs to the case that the material washing cover 270 moves between the open position of opening the discharge port 212 and the closed position of closing the discharge port 212. Optionally, the material washing cover 270 can be formed integrally with the mounting seat.

[0135] Optionally, the discharge port 212 can be closed by the material washing cover 270 and the stirring member 19 together, and further, a sealing member can be included, and the discharge port 212 can be closed by the material washing cover 270, the stirring member 19, and the sealing member together. The sealing member can be arranged on one or more of the material washing cover 270, the stirring member 19, and the main body of the material washing bin to better seal the discharge port 212.

[0136] Optionally, the material washing cover 270, the stirring member 19, and the mounting seat can be formed integrally.

[0137] Optionally, the discharge port 212 is sealed together by the washing hopper cover 270, the agitator 19, and the mounting base. Further, a sealing element is also included. The washing hopper cover 270, the agitator 19, the mounting base, and the sealing element seal the discharge port 212 together. The sealing element can be located on one or more of the washing hopper cover 270, the agitator 19, the mounting base, and the main body of the washing hopper. It is understood that the above sealing method of the discharge port 212 involves opening and closing part of the discharge port 212 by the washing hopper cover 270, and also involves the washing hopper cover 270 moving between an open position and a closed position of the discharge port 212, and also involves the washing hopper cover 270 opening and closing the discharge port 212.

[0138] like Figure 13 and Figure 17B As shown, the washing hopper cover 270 can be held in the closed position by magnetic connection in the initial state. Specifically, the washing hopper assembly 200 may also include a retaining member 237 and a retaining mating member 238. The retaining member 237 can be disposed on the washing hopper body 210. In other embodiments not shown, the retaining member 237 may be disposed on a mounting support frame. The mounting support frame is connected to the pot lid 4. This mounting support frame may be a separate support frame directly fixed to the pot lid 4. Both the retaining member 237 and the retaining mating member 238 are magnetic members. At least one of the retaining member 237 and the retaining mating member 238 is a magnet. For example, the retaining member 237 is a magnet, and the retaining mating member 238 is at least one of a magnet, iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel; the retaining member 237 is at least one of iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel, and the retaining mating member 238 is a magnet. Under the magnetic force between the retaining member 237 and the retaining fitting member 238, the washing chamber cover 270 is initially held in the closed position. Thus, the washing chamber cover 270 can be kept closed due to the magnetic force between the retaining member 237 and the retaining fitting member 238. When the washing chamber 211 is not in use, for example, when the cooking appliance 1 is not working or when the cooking appliance 1 is cooking, the discharge port 212 can remain closed, isolating the space of the inner pot 3 from the outside world. This prevents foreign objects such as dust and insects from entering the inner pot 3, thus keeping the inner pot 3 clean and uncontaminated when the cooking appliance 1 is not working, and ensuring good heat retention when the cooking appliance 1 is cooking, thereby improving cooking efficiency.

[0139] The retaining member 237 and the retaining mating member 238 are arranged vertically and opposite to each other in magnetic polarity, so that the magnetic force between them is a magnetic attraction. The washing hopper cover 270 is held in the closed position by the magnetic attraction between the retaining member 237 and the retaining mating member 238. For the illustrated embodiment, as Figure 17BAs shown, the retaining member 237 is located above the retaining fitting member 238. The retaining member 237 can be embedded in the washing hopper body 210, for example, by in-mold injection molding. Alternatively, in embodiments not shown, the retaining member 237 can also be detachably installed in the washing hopper body 210 by fasteners such as screws. The retaining member 237 can be provided on the top wall 216 of the hopper body.

[0140] In the illustrated embodiment, the retaining fitting member 238 and the translational fitting member 231 are formed as a single unit. In an embodiment not shown, the retaining fitting member 238 and the translational fitting member 231 are separate components.

[0141] Optionally, such as Figure 17C As shown, the upper end face of the translational mating part 231 can have an included angle α with the side end face of the rotary mating part 232, where 30°≤α≤150°, for example, α is 30°, 50°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 150°, etc. Preferably, 85°≤α≤95°. Thus, the magnetic fields generated by the translational mating part 231 and the rotary mating part 232 are independent and do not interfere with each other as much as possible. When the transmission body 310 is in the driving position, there is a first magnetic force between the translational driving member 321 and the translational mating member 231, and a second magnetic force between the rotary driving member 322 and the rotary mating member 232. The first and second magnetic forces are at an angle β, where 30°≤β≤150°. For example, β can be 30°, 50°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, or 150°. Preferably, 85°≤β≤95°. Figure 17C The diagram schematically shows that the translational mating member 231 is subjected to a first magnetic force Fa from the translational drive member 321, and the rotary mating member 232 is subjected to a second magnetic force Fb from the rotary drive member 322, with an included angle β between Fa and Fb.

[0142] like Figures 18-20As shown, the transmission assembly 300 can further include a transmission support 330, a mounting bracket 340, and a rotary drive device 301. The transmission support 330 can be located within the body central hole 313 and connected with the transmission body 310. The transmission body 310 can be rotatable relative to the transmission support 330. The mounting bracket 340 is located above the transmission body 310 and can be connected with the transmission support 330, for example, by fasteners such as screws. The rotary drive device 301 can be disposed on the mounting bracket 340, and its output shaft is connected with the transmission body 310 to rotate the transmission body 310. The mounting bracket 340 supports the rotary drive device 301 upward. In this embodiment, the rotary drive device 301 can move linearly together with the transmission body 310, so that the charged rotary drive device 301 can be disposed at a position other than the pot cover 4.

[0143] Specifically, the transmission support 330 can have a support facing surface 332 facing downward, which is used to abut against the linkage support surface 131. When the feeding bin 110 moves between the first position and the second position, the support facing surface 332 abuts against the linkage support surface 131, so that the transmission assembly 300 can move smoothly. When the feeding bin 110 moves between the second position and the additional position, the support facing surface 332 is separated from the linkage support surface 131.

[0144] The support facing surface 332 can be adapted to the shape of the linkage support surface 131, for example, also can be configured as an inclined surface inclined in the vertical direction, or a conical surface, for example, in the form of a ring. The transmission support 330 can be provided with a support central hole 331 and a support boss 333 extending radially outward. It can be understood that the support central hole 331 is located at the center of the transmission support 330. The feeding bin 110 can be located within the support central hole 331, and the support facing surface 332 is arranged around the support central hole 331. 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.

[0145] The top of the transmission body 310 can be provided with a gear portion 314 protruding upward, which surrounds the support central hole 331 and has a ring of teeth. The output shaft is provided with a transmission gear 302, and the teeth of the transmission gear 302 are engaged with the teeth of the gear portion 314. The illustrated embodiment schematically shows that there is one transmission gear 302 between the output shaft and the gear portion 314, however, the number of transmission gears 302 is not limited, and can be two or more as needed.

[0146] The mounting bracket 340 can be provided with a bracket guide portion 341 extending in the vertical direction. Referring back to Figure 10The vertical extension guide wall 102 can be provided corresponding to the storage bin 13. At least a portion of the guide wall 102 is located inside the storage bin 13 and connected to the fixed support 122 to separate the transmission structure from the space for storing food materials. Figure 10 The guide wall 102 is connected to the bottom wall of the storage bin 13, and a portion of the guide wall 102 is located above the bottom wall and a portion of the guide wall 102 extends downward from the bottom wall. The support guide portion 341 is located in the sliding channel 46 surrounded by the guide wall 102. The mounting support 340 can include a support base 342 and a support stand 343 located above the support base 342. The support base 342 can be provided with the support guide portion 341 integrally formed thereon. The support guide portion 341 can include three walls connected in sequence, for example, and the support stand 343 is located in a substantially square area surrounded by the three walls. The support stand 343 is detachably connected to the support base 342 by fasteners such as screws. The rotary drive device 301 is mounted to the support stand 343 and also located in the support guide portion 341. The middle part of the support stand 343 is provided with a support cylinder portion, and the output shaft of the rotary drive device 301 is located in the support cylinder portion. The lower end of the support cylinder portion abuts against the transmission gear 302 to limit the axial movement of the transmission gear 302.

[0147] As Figure 5 , Figure 8 , Figure 21 and Figure 22As shown, the first rotation axis Ax1 can be collinear with the second rotation axis Ax2. The washing cavity 211 is configured to be central symmetric, for example, the shape of the washing cavity 211 can be cylindrical. The central axis of the washing cavity 211 is collinear with the first rotation axis Ax1. The first rotation axis Ax1 and the second rotation axis Ax2 can both extend vertically. The central axis of the washing cavity 211 can also extend vertically. The plurality of rotation matching pieces 232 can be spaced apart along the circumference of the mounting seat 240, specifically, along the circumference of the second mounting seat 250. The plurality of rotation driving pieces 322 are spaced apart along the circumference of the transmission main body 310. The plurality of rotation matching pieces 232 are magnetically identical and are arranged centrally symmetrically around the first rotation axis Ax1. The plurality of rotation driving pieces 322 are magnetically identical and are arranged centrally symmetrically around the second rotation axis Ax2. The plurality of rotation matching pieces 232 are uniformly arranged along the circumference of the mounting seat 240; the plurality of rotation driving pieces 322 are uniformly arranged along the circumference of the transmission main body 310. In this way, the second mounting seat 250 can be subjected to equal magnetic forces in the circumferential direction and uniformly, so that the first rotation axis Ax1 and the second rotation axis Ax2 can remain collinear. The plurality of rotation matching pieces 232 can also be magnetically different, but the number of rotation matching pieces 232 with different magnetism needs to be equal. Preferably, the rotation matching pieces 232 with different magnetism are also uniformly and spaced apart under the premise of equal number, for example, a group of rotation matching pieces with first magnetism can be arranged first, then a group of rotation matching pieces with another magnetism is arranged, then a group of rotation matching pieces with first magnetism is arranged, then a group of rotation matching pieces with second magnetism is arranged, and so on. The adjacent two groups of rotation matching pieces are magnetically different but have the same number, the number of each group of magnet is the same and is greater than or equal to 1, which can be flexibly set according to needs, for example, the number can be two, three, four, five or six, etc. For example, the total number of rotation matching pieces 232 can be two and uniformly arranged, one of which has N-pole outward and the other has S-pole outward. The corresponding rotation driving piece can be provided as two. Or as shown in Figure 22 There are four groups of rotation matching pieces, each group has three magnet, one group of three magnet can be set as N-pole outward, and the adjacent group of three magnet can be set as S-pole outward, and the magnet poles of the rotation matching pieces outward are NNN, SSS, NNN, SSS respectively. Correspondingly, the plurality of rotation driving pieces 322 that match with them also need to be magnetically different, but the number needs to be equal and needs to be uniformly and spaced apart. For example, in Figure 22As shown, there are 16 rotating drive components, which can be arranged into 4 groups. In one group, the outward-facing magnetic poles of the four magnets are all designated as N poles, and the outward-facing magnetic poles of the four adjacent magnets are all designated as S poles. Therefore, the outward-facing magnetic poles of the rotating drive components are NNNN, SSSS, NNNN, and SSSS. During rotation, the outward-facing magnetic poles of the NNNN group of rotating drive components interact with the outward-facing magnetic poles of the SSS group of rotating mating components to generate magnetic force. Similarly, the outward-facing magnetic poles of the SSSS group of rotating drive components interact with the outward-facing magnetic poles of the NNN group of rotating mating components to generate magnetic force. This ensures that the second mounting base 250 experiences equal and uniform magnetic force in the circumferential direction.

[0148] The washing hopper assembly 200 may also include a limiting member. The mounting base 240 rotates around the limiting member, and the surfaces of the limiting member 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 member, which includes the inner sidewall 214 and the outer sidewall 215 of the washing hopper body 210.

[0149] The transmission body 310 is constructed in a centrally symmetrical shape, specifically a turntable shape as described above. The mounting base 240 is also constructed in a centrally symmetrical shape. Specifically, both the first mounting base 220 and the second mounting base 250 are cylindrical. In this embodiment, as described above, the mounting base 240 and the agitator 19 can be separate components, specifically the first mounting base 220 and the agitator 19 are separate components, to facilitate the installation of the washing hopper cover 270.

[0150] like Figure 21 As shown, when the transmission body 310 is in the first driving position and the second driving position, that is, when the rotary drive member 322 is in the driving position, the rotary drive member 322 and the rotary mating member 232 are radially aligned and their magnetic poles face opposite directions. At this time, the magnetic force between the rotary drive member 322 and the rotary mating member 232 is a magnetic attraction force, which causes the stirring member 19 to rotate. Figure 22 As shown, when the rotary drive 322 is in the drive position, it is radially offset from the rotary mating member 232, and their magnetic poles face each other. At this time, the magnetic force between the rotary drive 322 and the rotary mating member 232 is a magnetic repulsion force, which causes the stirring member 19 to rotate.

[0151] Multiple rotary drive components 322 are arranged at circumferential intervals along the transmission body 310. The transmission sidewall 312 has multiple transmission mounting surfaces 315 arranged circumferentially. Figure 10The transmission mounting surface 315 is planar and extends vertically, and the rotary drive member 322 is mounted to the transmission mounting surface 315. Multiple rotary mating members 232 are arranged at intervals along the circumference of the transmission body 310. The second mounting base 250 has multiple seat mounting surfaces 253 arranged circumferentially, the seat mounting surfaces 253 being planar and extending vertically, and the rotary mating members 232 are mounted to the seat mounting surfaces 253. One of the rotary mating members 232 and the rotary drive member 322 can be arranged in one row, and the other can be arranged in two rows at intervals along the vertical direction. Alternatively, both the rotary mating members 232 and the rotary drive member 322 can be arranged in one row, and one of them can be a vertically arranged elongated strip.

[0152] Pot lid

[0153] See back Figures 13-15 The pot lid 4 includes a pot lid body and a washing chamber body 210 connected to the pot lid body. The pot lid body and the side wall portion 6 of the washing chamber body 210 are constructed as one piece, and the chamber body base 217 is detachably connected to the pot lid body. When the cooking utensil 1 is located... Figure 2 In the initial state shown, there is a gap between the transmission assembly 300 and the washing chamber assembly 200 on the lid 4. Using this gap, the user can lift the lid 4 and the pot body 2 together from the base 12 and remove them together, or the user can remove only the lid 4 from the pot body 2 to clean the washing chamber 211 and the agitator 19. The lid 4 is provided with a drainage structure communicating with the drain outlet 213 of the washing chamber body 210 and the wastewater tank 48, for draining washing water to the wastewater tank 48. Specifically, the drainage structure has a drainage pipe 10, which includes a drainage channel 105 and a pipe connector 106 located on the side wall 6, and a drainage pipe 107. The drainage channel 105 connects the drain outlet 213 and the pipe connector 106, and one end of the drainage pipe 107 is connected to the pipe connector 106, while the other end extends to the wastewater tank 48.

[0154] Optionally, as illustrated in the embodiment, the drain pipe 10 may include a siphon pipe with an inverted U-shaped structure. As an example, the drain channel 105 may be configured in an inverted U-shape as a siphon pipe. The pipe connector 106 is located in the middle of the side wall portion 6. This allows for siphon drainage. Alternatively, the drain structure may be configured such that the drain outlet 213 is level with or higher than the drain channel. This allows for gravity drainage. In this embodiment, wastewater can flow by gravity from the washing chamber 211 to the wastewater tank 48 using the water level difference, avoiding the use of a water pump. This reduces the number of internal components of the cooking appliance 1 and lowers production costs.

[0155] Optionally, other sewage discharge modes can also be adopted, such as setting a separate electromagnetic valve door that opens and closes the sewage discharge port 213, and directly controlling whether to discharge water by directly controlling the opening and closing state of the electromagnetic valve door.

[0156] Optionally, the pot cover 4 can include a pot cover body and a detachable cover (not shown) detachably connected to the pot cover body. Part or all of the sewage pipeline 10 can be detachably or non-detachably arranged on the detachable cover. When the user intends to clean the sewage pipeline 10, the detachable cover can be removed for cleaning.

[0157] Referring back to Figure 1 and Figure 2 , the cooking appliance 1 further comprises a water inlet assembly for supplying water to the material washing cavity 211. The water inlet assembly can include a clean water tank 81 and a water inlet pipe (not shown). The outlet of the clean water tank 81 can be in communication with the water inlet port 113 of the feeding bin 110 through the water inlet pipe, and for example, an electrically controlled valve can be arranged therebetween to control water inlet. The clean water in the clean water tank 81 can be self-flowed to the feeding bin 110 through the high and low difference of water, or delivered to the feeding bin 110 by a water pump. The clean water tank 81 is detachably arranged on the machine body assembly 11, so that the user can conveniently perform water filling operation. The clean water tank 81 is arranged close to the material storage mechanism and above the sewage tank 48. The water inlet pipe can be located in the material storage mechanism. For the scheme of arranging a water pump, the water pump can also be located in the material storage mechanism.

[0158] As shown in Figure 1 and Figure 2 , the machine body assembly 11 further comprises a main frame 101. The pot body 2 is located on a first side of the main frame 101. As shown above, the feeding mechanism 100 is used to deliver the food material in the material storage mechanism to the material washing cavity 211. The material storage mechanism, the feeding mechanism 100 and the transmission assembly 300 can all be located on the first side of the main frame 101 and above the material washing bin assembly 200. In this way, the feeding mechanism 100 can be close to the material storage mechanism, occupy space, and the material can be automatically fed into the material washing cavity 211 through the feeding mechanism 100 by gravity, without additional driving devices such as a feeding pump and feeding pipelines, thereby reducing cost, simplifying the structure of the cooking appliance 1, and being conducive to product miniaturization; the transmission assembly 300 can drive the stirring piece 19 from above the material washing cavity 211, so that the electrically charged driving device can be arranged at a position other than the pot cover 4, facilitating the user to clean the pot cover 4 and the material washing bin assembly 200.

[0159] The water inlet assembly and the sewage discharge assembly can be arranged on a second side of the main frame 101 different from the first side. Specifically, the clean water tank 81 and the sewage tank 48 are arranged on the second side of the main frame 101. Figure 1The first side and the second side of the main frame 101 are shown facing away from each other. The clean water tank 81 can be positioned above the sewage tank 48, i.e. the clean water tank 81 is positioned directly above the sewage tank 48. The clean water in the clean water tank 81 can flow to the feeding bin by itself due to the difference in height, without the need to set a booster pump.

[0160] The cooking appliance 1 can further include a main board and a display board. The display board can be arranged at the front side of the material storage mechanism, specifically the feeding bin 13. The outer side of the display board can be provided with a control panel. The main board can be arranged in the main frame 101. The main board is positioned above the sewage tank 48 and on the side of the clean water tank 81 facing the pot body 2. The sewage tank 48 can be provided with a top opening to receive sewage and water from the sewage pipe 10.

[0161] The cooking appliance 1 can further include a powered device. The powered device is arranged in the main frame 101, not arranged in the pot cover 4 and the pot body 2. The powered device includes a driving device for driving the transmission assembly 300 to rotate partially and move linearly, a main board, a heating device, a display board, etc. The powered device can be arranged at a position other than the pot cover 4 and the pot body 2, which is convenient for the user to clean the pot cover 4, the material washing bin assembly 200 and the inner pot in the pot body 2, and the powered device does not need to be considered for waterproofing during the manufacturing stage of the pot cover 4 and the pot body 2.

[0162] According to another aspect of the present application, a control method is provided. The control method is implemented by the cooking appliance and the control device thereof. As shown in the Figure 23 The control method includes the following steps: S1 preparing for discharging, S2 discharging, S3 water feeding, S4 material washing, S5 water draining, S6 preparing for rotating and discharging, S7 rotating and discharging, and S8 resetting, etc. The control device is configured to control the cooking appliance to perform the above steps.

[0163] S1 preparing for discharging

[0164] The transmission assembly 300 is controlled to move downward from the initial position to the first driving position, and the material washing bin cover 270 is kept in the closed position to close the discharging port. In this way, the transmission assembly 300 is positioned at the material washing station to prepare for driving the stirring member 19 to rotate, and the material washing bin cover 270 is positioned at the closed position to isolate the material washing cavity 211 from the inner pot 3, so as to prevent the material and water from entering the inner pot 3.

[0165] For the illustrated embodiment, the material washing bin cover 270 is in the closed position in the initial state (as shown in FIG. 1), and the transmission assembly 300 is in the initial position. Figure 2As shown in FIG. 6, in this scheme, no action is performed on the washing bin cover 270 during the preparation of the discharging process, and the action of positioning the transmission assembly 300 to the washing station is performed alone. In an embodiment not shown, the washing bin cover 270 can be in the open position in the initial state. In this scheme, not only the action of positioning the transmission assembly 300 to the washing station is performed, but also the action of positioning the washing bin cover 270 to the closed position is performed, so that the preparation of the discharging process further comprises: by controlling the transmission assembly 300 to move downward from the initial position to the first driving position, the washing bin cover mounting seat drives the washing bin cover to move from the open position to the closed position by the first magnetic force upward. This method controls the washing bin cover 270 and the transmission assembly 300 to be positioned at the same time.

[0166] S2 performs discharging

[0167] The feeding bin 110 is moved downward to a position where the feeding channel is in communication with both the storage bin 13 and the washing cavity 211, i.e., an additional position (as shown in FIG. 5), so as to send the material in the storage bin 13 into the washing cavity 211. The feeding bin 110 extends into the washing cavity 211 through the inlet 201, the inlet 111 on the side wall thereof can be in communication with the storage bin 13, and the outlet 112 on the side wall thereof can be in communication with the washing cavity 211. After the discharging is completed, the feeding bin 110 is moved upward to a position where the feeding channel is not in communication with the washing cavity, for example, the first driving position in the second position (as shown in FIG. 6). Figure 4 Figure 5

[0168] S3 performs water feeding

[0169] Water is supplied to the washing cavity 211. Optionally, water is supplied to the washing cavity 211 through the water feeding channel of the feeding bin 110, the inlet 201. The sequence of water feeding and discharging is not limited. Preferably, water feeding can be performed after discharging, or discharging can be performed after water feeding, or water feeding can be performed during discharging to save time. It should be noted that the outlet 114 is located on the lower surface of the feeding bin 110, and when the feeding bin 110 is located above the washing cavity 211, the position thereof can be regarded as the position where the feeding bin 110 is in communication with the washing cavity 211, for example, the additional position, the first driving position and the second driving position. The feeding bin 110 can supply water to the washing cavity 211 at these positions. The water in the water tank 81 can be supplied to the washing cavity 211 through the water feeding pipe and the water feeding channel of the feeding bin 110. After the discharging is completed and before or after the water feeding is completed, the feeding bin 110 is moved upward to a position where it is not in communication with the washing bin. The inlet 201 can be one, and the material and water are both sent into the washing cavity 211 from the one inlet 201. Alternatively, the inlet 201 can be two or more, and the material and water are respectively sent into the washing cavity 211 from different inlets 201.

[0170] S4 performs material washing

[0171] ​​The transmission assembly 300 in the first driving position drives the stirring assembly mounting seat to rotate the stirring assembly 19 to perform the washing operation. In the step of performing the washing operation, the transmission assembly 300 has a second magnetic force between the first driving position and the stirring assembly mounting seat. Through the second magnetic force, the transmission assembly 300 drives the stirring assembly mounting seat to rotate the stirring assembly 19. Specifically, the transmission body 310 in the first driving position is controlled to rotate around the second rotation axis, and the stirring assembly mounting seat is subjected to the circumferential magnetic force and rotates around the second rotation axis with the transmission body 310 to drive the stirring assembly 19 in the washing cavity 211 to rotate. The transmission assembly 300 and the stirring assembly 19 rotate synchronously, and the rotation of the stirring assembly 19 can realize the washing operation.

[0172] For the illustrated embodiment, the second mounting seat 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 seat 220 as the stirring assembly mounting seat rotates with the second mounting seat 250 under the action of the second magnetic force to drive the stirring assembly 19 to rotate. In an embodiment not shown, the stirring assembly mounting seat 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 stirring assembly mounting seat drives the stirring assembly 19 to rotate under the action of the second magnetic force.

[0173] It should be noted that the above-mentioned steps of discharging, water feeding and washing are not limited in the order, which can be sequentially performed, i.e., discharging-water feeding-washing; or water feeding during discharging and washing after water feeding; or water feeding before discharging and washing after discharging; or discharging and water feeding during washing, etc.

[0174] S5 performs the water draining

[0175] After the washing operation is completed, the sewage in the washing cavity 211 is drained, specifically from the sewage outlet at the bottom of the washing cavity 211 to the sewage tank 48 through the sewage pipeline 10. The water draining mode can be gravity water draining and siphon water draining. For the siphon water draining scheme, the step of performing the water draining further includes supplying water to the washing cavity 211 so that the water level in the washing cavity 211 is higher than the highest part of the siphon pipeline to trigger the siphon water draining.

[0176] S6 prepares the rotating discharging

[0177] The control transmission assembly 300 is moved upwardly from the first driving position by a first distance L1 to a non-driving position to reduce the first magnetic force, so that the material washing bin cover 270 is moved downwardly from the closed position to the open position due to gravity. The control transmission assembly 300 is moved downwardly from the non-driving position by a second distance L2 to a second driving position, and the material washing bin cover 270 remains in the open position. When the material washing bin cover 270 is in the open position, the material washing cavity 211 is in communication with the inner pot 3. The first distance L1 is greater than the second distance L2. That is, the second driving position is above the first driving position.

[0178] In the embodiment, the switching between the two driving positions is achieved by adjusting the up-down position of the transmission assembly 300, which is easy to operate. The transmission assembly 300 is first moved upwardly by the first distance L1 to move the material washing bin cover 270 from the closed position of closing the discharge port 212 to the open position of opening the discharge port 212, and then the transmission assembly 300 is moved downwardly by the second distance L2 to keep the material washing bin cover 270 in the open position while switching the transmission assembly 300 from the material washing station to the material dropping station (i.e. the second driving position). Thus, the transmission assembly 300 only needs to be moved upwardly by a distance of L1-L2 to switch from the first driving position to the second driving position.

[0179] By such control, not only the opening of the discharge port 212 and the switching between the material washing station and the material dropping station can be achieved to smoothly perform the material washing process, but also the height of the transmission main body 310 can be reduced to optimize the structure of the cooking appliance 1. The control method of the embodiment can design the height of the transmission assembly 300 to be a desired smaller size. On the one hand, the distance between the transmission assembly 300 and the pot cover 4 can be reasonably designed to make it easier to place and take the pot body 2 and the pot cover 4, and the pot body 2 and the pot cover 4 will not touch the machine body assembly 11, avoiding damage caused by the machine body assembly 11. On the other hand, the overall height of the cooking appliance 1 can be reduced, which is beneficial to product miniaturization.

[0180] The first distance L1 can be 6mm-100mm, for example, 6mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm. The difference between the first distance and the second distance L1-L2 can be 5mm-20mm, for example, 5mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm.

[0181] The height of the transmission body 310 of the transmission assembly 300 of the present solution can be reduced by a size less than or equal to the first distance L1 in the solution where the first distance L1 is equal to the distance of the movement of the material washing bin cover 270 between the open position and the closed position, the height of the transmission body 310 is reduced by a size equal to the first distance L1 in the solution where the first distance L1 is greater than the distance of the movement of the material washing bin cover 270 between the open position and the closed position, and the height of the transmission body 310 is reduced by a size less than the first distance L1.

[0182] Optionally, the first distance L1 can be 20mm-30mm. One 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 25mm and the second distance is 5mm.

[0183] The beneficial effects of the present control method are described below in a comparative manner.

[0184] As an example, it can be defined that:

[0185] The stroke of the movement of the material washing bin cover 270 between the open position and the closed position is a, as shown in Figure 7 It should be noted that the stroke a is generally related to the ratio of the size of the material washing bin cover 270 and the size of the discharge port.

[0186] The stroke of the movement of the transmission body 310 between the material washing station and the material dropping station is b.

[0187] The coupling width between the translational cooperation piece 231 and the translational driving piece 321 that can produce effective coupling is L.

[0188] The thickness of the bin body top wall 216 of the material washing bin body 210 is t, as shown in Figure 7 .

[0189] The height of the transmission assembly 300, specifically the height of the transmission body 310 is H, as shown in Figure 1 . The height H satisfies the following relationship: H=L+b+t. It can be seen that the stroke b is reduced, and the height H is correspondingly reduced.

[0190] For the embodiment of directly switching the transmission assembly 300 from the material washing station to the material dropping station, in order to simultaneously open the material washing bin cover 270 during switching, the stroke b1 includes the stroke a. That is, the height H1=L+b1+t.

[0191] For the embodiment of the present embodiment that increases the execution action to directly switch the transmission assembly 300 from the material washing station to the material dropping station, the stroke b2 does not include the stroke a. That is, the height H2=L+b2+t. Therefore, H1-H2=a, and thus the height H of the transmission body 310 of the present embodiment is reduced by the size a. When the overall height of the cooking utensil 1 is unchanged, the spacing distance D (as shown in Figure 1 the transmission assembly 300 and the material washing bin body 210 on the pot cover 4 can be increased by the size a, so that the placement and taking of the pot body 2 and the pot cover 4 are more easily operated. Of course, if necessary and / or desired, the size a of the transmission assembly 300 can be designed to be reduced to make the overall height of the cooking utensil 1 smaller, and the spacing distance D between the transmission assembly 300 and the pot cover 4 is adjusted to a suitable value.

[0192] As an example, the stroke a=20mm, the stroke b1=22mm, the coupling width L=10mm, and the thickness t=6mm. The height H1=L+b1+t=38mm, and the height H2=H1-a=18mm.

[0193] S7 performs rotation and dropping of material

[0194] The transmission assembly 300 in the second driving position drives the stirring part mounting seat to rotate together with the stirring part 19. In the step of performing rotation and dropping of material, the transmission assembly 300 has a second magnetic force between the first driving position and the stirring part mounting seat. Through the second magnetic force, the transmission assembly 300 drives the stirring part mounting seat to rotate together with the stirring part 19. Specifically, the transmission body 310 of the transmission assembly 300 in the second driving position is controlled to rotate around the second rotation axis, and the stirring part mounting seat is rotated around the second rotation axis together with the transmission body 310 under the action of the circumferential magnetic force to drop the material in the material washing cavity 211 into the inner pot 3. In the illustrated embodiment, the material washing bin cover 270 rotates together with the stirring part 19 thereon to achieve the material throwing action during dropping of material.

[0195] S8 performs reset

[0196] The material washing bin cover 270, the transmission assembly 300, and the material feeding bin 110 are reset. It should be noted that the reset action can be performed at any stage after the dropping of material. For example, water can be added to the inner pot 3 before the reset, and the material washing bin cover 270, the transmission assembly 300, and the material feeding bin 110 are reset after the water is added. For example, the reset is performed after the cooking is completed.

[0197] For the illustrated embodiment, the material washing cover 270 is in the closed position in the initial state, and the resetting of the material washing cover 270 can be performed, and thus the resetting includes controlling the transmission assembly 300 to move from the second driving position to the first driving position, and the material washing cover 270 is moved from the open position to the closed position by the upward magnetic force to achieve the resetting of the material washing cover 270. In an embodiment not shown, the material washing cover 270 is in the open position in the initial state, and in this case, no action is performed on the material washing cover 270 during the resetting.

[0198] The control method further includes controlling the feeding bin 110 to move up and down to drive the transmission assembly 300 to move along the straight line together, controlling the straight line driving device 120 to drive the feeding bin 110 to move along the straight line, and controlling the rotary driving device 301 to drive the transmission main body 310 of the transmission assembly 300 to rotate.

[0199] In the steps of preparing the discharging, preparing the rotary discharging, and performing the resetting, the movement of the transmission assembly 300 is achieved by controlling the movement of the feeding bin 110. Specifically, the straight line driving device 120 is controlled to drive the feeding bin 110 to move along the straight line, and the feeding bin 110 is engaged with the transmission assembly 300 to drive the transmission assembly 300 to move up and down. In the step of performing the resetting, the feeding bin 110 is controlled to move upward to drive the transmission assembly 300 to move upward to the initial position together. In the steps of performing the material washing and performing the discharging, the rotary driving device 301 is controlled to drive the transmission main body 310 of the transmission assembly 300 to rotate, thereby driving the material washing cover 270 and the stirring member 19 thereon to rotate.

[0200] For the illustrated embodiment, the stirring member 19 and the material washing cover 270 are both arranged in the first mounting seat 220, and in this embodiment, the control method further includes driving the material washing cover 270 to move between the open position and the closed position together with the stirring member 19. In other embodiments not shown, the cover mounting seat and the stirring member mounting seat are separate components and are independently arranged, and in this embodiment, the control method further includes independently driving the material washing cover 270 to move between the open position and the closed position, and independently driving the stirring member 19 to rotate.

[0201] The above-mentioned control steps can be performed by a control device to control the cooking appliance.

[0202] The following description is made with reference to Figures 2-9 The entire material washing process of the cooking appliance 1 of the present embodiment is described as follows:

[0203] As Figure 2As shown, the cooking appliance 1 is in an initial state. At this time, the feeding bin 110 and the transmission assembly 300 are both in initial positions in the first positions, the feeding bin 110 is not communicated with the outlet of the storage bin 13 and the inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is in the closed position. In the initial state, the force relationship of the washing bin cover 270 is F1+F2≥G1+G2, wherein F1 is the magnetic force between the translational fitting member 231 and the translational driving member 321; F2 is the magnetic force between the retaining member 237 and the retaining fitting member 238; G1 is the total weight of the washing bin cover 270 and the follow-up load moving linearly therewith, in the embodiment, the follow-up load at least includes the first mounting seat 220, the translational fitting member 231 and the stirring member 19; and G2 is the weight of the water and the material in the washing cavity 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 even can be close to or equal to 0, when F1=0, F2≥G1+G2; F2 is maximum, i.e. F2max; and G2=0, or G2 is the weight of the small amount of residual water in the washing cavity 211 after washing.

[0204] When it is intended to carry out the discharging operation, first, the linear driving device 120 can drive the screw rod 121 to act, so that the screw rod 121 can drive the feeding bin 110 to move downward to the first driving position in the second position. As shown in Figure 3 As shown, the cooking appliance 1 is in a preparation state for discharging. At this time, the feeding bin 110 and the transmission assembly 300 are both in the first driving position in the second position, the feeding bin 110 is still not communicated with the outlet of the storage bin 13 and the inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is still in the closed position. In the Figure 3 In the state shown, the force relationship of the washing bin cover 270 is F1+F2>G1+G2, wherein F1 and F2 are maximum, i.e. F1max, F2max, and G2 is the same as in the initial state. Thus, the washing bin cover 270 is subjected to upward magnetic force and the magnetic force connection in the radial direction of the washing bin assembly 200. Then the linear driving device 120 can continue to drive the screw rod 121 to act, the feeding bin 110 continues to move downward and extends into the washing cavity 211, and the transmission assembly 300 does not move therewith. As shown in Figure 4As shown, the cooking appliance 1 is in the feeding state. At this time, the feeding bin 110 is in the auxiliary position, the transmission component 300 is in the first drive position of the second position, and the feeding bin 110 is still connected to the outlet of the storage bin 13 and the inlet 201 of the washing bin component 200. 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 inlet 111, and then enters the washing chamber 211 through the outlet 112 to perform the feeding action. The amount of material flowing into the washing chamber 211 can be calculated by time. The cooking appliance controls the time when the feeding bin 110 is in the auxiliary position according to the amount of material required by the user to achieve quantitative feeding. Water can also be supplied to the washing chamber 211 in this feeding state. Feeding and water supply can be carried out simultaneously, or water supply can be carried out after feeding is completed. The clean water in the clean water tank 81 enters the feeding hopper 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 force relationship of the washing hopper cover 270 is F1+F2>G1+G2, where F1 and F2 are F1max and F2max, and G2 is the weight of water and material.

[0205] When the feeding operation is completed, the linear drive device 120 drives the screw 121 to move again. The screw 121 drives the feeding bin 110 to move upward to the first drive position in the second position, as shown. Figure 5 As shown. In Figure 5 In the state shown, water can be supplied to the washing chamber 211, or it can also be... Figure 4 Water is supplied to the washing chamber under the specified condition. When... Figure 5 When water is supplied in the state shown, the weight of G2 increases. After water supply is completed, the rotary drive device 301 can drive the transmission body 310 to rotate, and the magnetic force between the rotary drive component 322 and the rotary mating component 232 can drive the second mounting base 250 to rotate, thereby driving the first mounting base 220 and the stirring component 19 on it to rotate together to perform the washing action. It can be understood that, in the illustrated embodiment, when the washing action is performed, the water level in the washing chamber 211 is lower than the highest part of the drain pipe 10. In other embodiments not shown, a separate solenoid valve for opening and closing the drain port 213 can be provided, and the drainage can be directly controlled by directly controlling the opening and closing state of the solenoid valve. This drainage method does not restrict the water level in the washing chamber 211 to be lower than the highest part of the drain pipe.

[0206] For the illustrated embodiment, when the washing action is completed and the draining is intended to be carried out, water is supplied to the washing chamber 211 first until the water level in the washing chamber 211 is higher than the highest part of the drain pipe 10, and the draining is carried out by using the siphon principle. And the highest position of the draining passage will have a velocity head, thus forming the full flow of the drain pipe 10. When the water level height drops below the highest position of the drain pipe 10, since the draining passage at this position is already in the full flow state, at this time, since the water level in the washing chamber 211 is higher than the water level at the outlet 114 of the drain pipe 107, according to Bernoulli's principle, the outlet of the drain pipe 107 will have a velocity head at this time, and the water in the washing chamber can be drained completely. When the draining is completed, the force relationship of the washing chamber cover 270 is F1+F2>G1+G2, wherein F1, F2 are F1max, F2max, and G2 is the weight of the material after being absorbed water and a small amount of residual water. If necessary, clean water can also be added after draining for cooking; in this case, G2 is the weight of the material after being absorbed water and clean water.

[0207] The actions of water supply, material washing and draining can be repeatedly performed to realize multiple washing of a single material.

[0208] When the draining action is completed and the discharging is intended to be carried out, the linear drive device 120 drives the feeding chamber 110 to move upward to the middle position in the first position, as shown in Figure 6 In the state shown in Figure 6 , the force relationship of the washing chamber cover 270 is F1+F2<G1+G2, wherein F1 decreases, i.e. F1<F1max, F2 is F2max, and G2 is the same as when the draining is completed. Since F1+F2<G1+G2, the washing chamber cover 270 is unbalanced in force and cannot remain in the closed position and will move downward, and the discharging port 212 will be opened. The cooking appliance is quickly switched from the state shown in Figure 6 to the state shown in Figure 7 , i.e. the washing chamber cover 270 moves downward to the open position, and in this process F1 continues to decrease and F2 decreases. As shown in Figure 7 , the washing chamber cover 270 has been located in the open position, and the discharging port 212 has been opened. At this time, part of the material and / or water will fall into the inner pot 3, and G2 decreases. In the state shown in Figure 7 , the force relationship of the washing chamber cover 270 is F1+F2<G1+G2, wherein F1<F1max, F2 is the minimum, i.e. F2min, and G2 is the weight of the remaining material after being absorbed water and a small amount of residual water. Then the linear drive device 120 drives the screw rod 121 to move the transmission main body 310 from the middle position to the second driving position in the second position. At this time, as shown in Figure 8As shown, the cooking appliance 1 is in the unloading state. The distance d1 exists between the translational driving member 321 and the translational cooperating member 231, and the force relationship of the material washing bin cover 270 is F1+F2 Figure 7 As shown, the same as the state, so that in the unloading process, the material washing bin cover 270 always remains in the open position. Then the rotary driving device 301 drives the transmission main body 310 to rotate again, so that the stirring member 19 rotates, starts to spin the material, and performs the unloading action, and the material is quickly unloaded into the inner pot 3 under the action of the centrifugal force. When the material is spinning, G2 continues to decrease, and after the spinning is completed, the force relationship of the material washing bin cover 270 is F1+F2

[0209] When the unloading action is completed and the reset needs to be performed, the linear driving device 120 continues to drive the screw rod 121 to move the transmission main body 310 from the second driving position to the first driving position, as shown in Figure 9 As shown, in this process, F1 increases, and at this time, the distance d2 exists between the translational driving member 321 and the translational cooperating member 231, d2 is smaller than d1, and the force relationship of the material washing bin cover 270 is F1+F2>G1+G2, wherein F1 is F1max, F2 is F2max, and G2 is the weight of a small amount of residual water, so that the material washing bin cover 270 is moved upward to the closed position under the action of the magnetic force, for example Figure 3 As shown, the reset of the material washing bin cover 270 is achieved. The cooking appliance is quickly switched from Figure 9 As shown, to the state shown in Figure 3 As shown, the material washing bin cover 270 is moved upward to the closed position, and in this process, F1 continues to increase to F1max, F2 increases to F2max, and G2 is the weight of a small amount of residual water, so that the force relationship of the material washing bin cover 270 is F1+F2 Figure 9 The same as the state, at this time, F1+F2>G1+G2.

[0210] The actions in the process of unloading to unloading can be repeatedly performed to achieve the material washing of the material multiple times; that is, the states shown in Figures 3-9 As shown, are repeatedly performed.

[0211] Then the linear driving device 120 drives the material feeding bin 110 to move upward to the initial position in the first position, as shown in Figure 2 As shown, the reset of the material feeding bin 110 and the transmission assembly 300 is achieved. In this process, F1 decreases to be smaller, and can even be close to or equal to 0, F2 is F2max, and G2 is the weight of a small amount of residual water, so that the force relationship of the material washing bin cover 270 is F1+F2 Figure 9 The same as the state, at this time, F1+F2>G1+G2.

[0212] It can be understood that in other embodiments not shown, the material washing bin cover 270 can be in the open position in the initial state. In other words, when the cooking appliance 1 is not working, the discharge port 212 can be in the open state, i.e. the material washing bin cover 270 is in the open position in the initial state. Specifically, in addition to canceling the retaining member 237 and the retaining cooperating member 238, the rest of the structure is the same as that of the cooking appliance of the illustrated embodiment, and for the sake of brevity, only the differences are described in detail here. Specifically, the material washing bin assembly 200 does not include the retaining member 237 and the retaining cooperating member 238, i.e. there is no F2, F2 being the magnetic force between the retaining member 237 and the retaining cooperating member 238. Therefore, in the initial state, when the material feeding bin 110 and the transmission assembly 300 are both in the initial position in the first position, the material feeding bin 110 is not in communication with the outlet of the material storage bin 13 and the inlet 201 of the material washing bin assembly 200, and the material washing bin cover 270 is in the open position.

[0213] In the initial state, the force relationship of the material washing bin cover 270 is F1 < G1 + G2, in which state F1 is small, and can even be close to or equal to 0, G2 = 0, or G2 is the weight of a small amount of residual water in the material washing cavity 211 after washing. When it is intended to carry out the discharging operation, it is necessary to first move the material washing bin cover 270 from the open position to the closed position, i.e. the linear drive device 120 can drive the screw rod 121 to act, so that the screw rod 121 can drive the material feeding bin 110 to move downward to the first driving position in the second position (as shown in FIG. 8). At this time, the force relationship of the material washing bin cover 270 is F1 > G1 + G2, and under the action of the magnetic force, the material washing bin cover 270 moves to the closed position. Figure 3

[0214] ​The rest of the discharging operation, the washing operation, the draining operation, the dropping operation, and the water supplying operation are the same as the operation of the cooking appliance of the illustrated embodiment, and the only difference is that the magnetic force received by the washing bin cover 270 is F1, not F1+F2, i.e., there is no magnetic force of F2, but the force relationship of the magnetic force of the washing bin cover 270 in the discharging phase, the washing phase, the draining phase, and the dropping phase is consistent with the force relationship of the cooking appliance of the illustrated embodiment in the same phase, and the operation of the linear driving device 120 and the rotary driving device 301 is also consistent. Taking the dropping phase as an example, for the embodiment in which the discharging port 212 is in a normally open state, the force relationship of the washing bin cover 270 is F1>G1+G2; for the illustrated embodiment, the force relationship of the washing bin cover 270 is F1+F2>G1+G2. The magnetic force of the discharging phase of the two embodiments is greater than G1+G2, i.e., the size relationship is consistent. The difference is that after the dropping operation is completed, the washing bin cover 270 does not need to be reset, i.e., the washing bin cover 270 remains in the open state, and after the linear driving device 120 drives the feeding bin 110 to move upward to the initial position in the first position, the washing bin cover 270 continues to remain in the open state.

[0215] In addition, in an embodiment not shown, a water supply pipe that can be in communication with the washing cavity 211 can be separately provided to directly supply water to the washing cavity 211. In this way, water can be supplied to the washing cavity 211 at any stage of the entire washing operation. A feeding device that can be in communication with the washing cavity 211 can be provided, and the feeding device can be immovable relative to the storage bin 13, and the feeding device is provided with a feeding member such as a rotary screw rod to feed the washing cavity 211.

[0216] In addition, in other embodiments not shown, the translational cooperation member 231 and the rotary cooperation member 232 are both located inside the washing cavity 211. When the rotary driving member 322 is in the driving position, i.e., when the transmission main body 310 is located in the first driving position and the second driving position, the rotary driving member 322 is located radially inside the rotary cooperation member 232. In this way, the external structure of the cooking appliance is simple, which is conducive to product miniaturization; and the structure of the transmission assembly 300 can be simpler.

[0217] As an example, a cylindrical mounting seat located inside the washing cavity 211 can be included. The washing bin cover 270 and the stirring member 19 can both be connected to the mounting seat. The rotary cooperation member 232 and the translational cooperation member 231 are provided on the mounting seat. The washing bin main body 210 is provided with a groove portion located inside the washing cavity. The groove portion forms a receiving groove to receive the translational driving member 321 and the rotary driving member 322, more specifically, to receive the transmission main body.

[0218] It should be noted that the force relationship mentioned in the present text can be understood as the force relationship of the assembly composed of the washing material bin cover 270 and the follow-up load moving along with it in a straight line, and for the sake of brevity, it is simply referred to as the force relationship of the washing material bin cover 270; similarly, the description of the washing material bin cover 270 used in the present text, such as being subjected to magnetic force, force, magnetic force, gravity and other forces, can be understood as various descriptions of the forces of the assembly composed of the washing material bin cover 270 and the follow-up load moving along with it in a straight line, and for the sake of brevity, the washing material bin cover 270 is replaced, as an example, the washing material bin cover 270 is subjected to magnetic force, which means that the assembly composed of the washing material bin cover 270 and the follow-up load moving along with it in a straight line is subjected to magnetic force.

The processes described in all the preferred embodiments described above are only examples. Unless an adverse effect occurs, various processing operations can be performed in a different order from the above processes.
