The following describes in detail the transmission structure among the feeding mechanism 100, the transmission assembly 300 and the washbin assembly 200 with reference to the drawings.
The feeding mechanism 100 may be connected to the driving assembly 300 by means of a contact type driving. The transmission assembly 300 may be coupled with the washing bin assembly 200 by magnetic force generated by a magnetic member, and a contactless transmission may be configured between the transmission assembly 300 and the washing bin assembly 200. In this embodiment, the wash bin cover 270 may be in a closed position or an open position in the initial state. In other words, the discharge opening 212 may be in a normally closed state or a normally open state when the cooking appliance 1 is not in operation.
In the illustrated embodiment, one embodiment of the transmission structure between the feed mechanism 100, the transmission assembly 300, and the wash bin assembly 200 is shown. And the discharge opening 212 is shown schematically in a normally open position.
As described above, the feeding bin 110 is linearly movable together with the driving assembly 300 between the first position and the second position. As shown in fig. 5, the feed magazine 110 also has additional locations. The feed bin 110 is closer to the wash chamber 211 in the additional position. The feeding bin 110 has a feeding channel for conveying solid material, which is not in communication with the storage bin 13 and the washing chamber 211 in the first position and the second position. When the feeding bin 110 is moved to the additional position, the transmission assembly 300 does not move therewith. Therefore, the feeding bin 110 can extend out relative to the transmission assembly 300 and into the washing cavity 211 when in an additional position, and the feeding channel of the feeding bin 110 can be communicated with both the storage bin 13 and the washing cavity 211. In this embodiment, the feed magazine 110 has a two-stage motion relative to the drive assembly 300, wherein in one stage of motion, i.e. moving from the first position to the second position, and the second position returning to the first position, the feed magazine 110 moves with the drive assembly 300; in another segment of the movement, i.e. from the second position to the additional position, and from the additional position to the second position, the feed magazine 110 moves away from the drive assembly 300. The feed bin 110 can be moved from the second position to additional positions, and from the additional positions to the second position, such that the feed bin 110 can enter or exit the wash chamber 211 to facilitate and terminate the blanking.
The wash bin assembly 200 is located below the drive assembly 300. When the feeding bin 110 is in the additional position, the transmission assembly 300 may abut against the top surface of the wash bin body 210, such that the transmission assembly 300 can stop moving when the feeding bin 110 moves from the second position to the additional position. In other embodiments not shown, a separate fixed support frame is included, by which the transmission assembly 300 is abutted when the magazine 110 is in the additional position, which may be a separate support frame fixed directly to the lid 4.
As shown in fig. 9-11, the feeding mechanism 100 may further include a linkage 130. The link 130 is disposed at the bottom of the feeding bin 110, for example, the bottom surface of the feeding bin 110 is provided with a rotary connecting structure 117, the link 130 is provided with a structure matched with the rotary connecting structure 117, and the link 130 is rotated to be connected to the rotary connecting structure 117. And the link 130 is fixed to the rotational connection structure 117 with a screw. The transmission body 310 is provided with a body center hole 313, and it is understood that the body center hole 313 is located at the center of the transmission body 310. The feed bin 110 is located within the central body bore 313.
The link 130 is located at a lower side of the transmission body 310 and is provided with an upward-facing link supporting surface 131 for supporting the transmission assembly 300 upward. By means of the linkage support surface 131, the feeding bin 110 can drive the transmission assembly 300 to move upwards. For the illustrated embodiment, the transmission assembly 300 may move downward with the feed bin 110 as it moves downward by its own weight. The linking support surface 131 may be configured as a slope inclined in the vertical direction, and the illustrated embodiment shows the linking support surface 131 as a conical surface having an annular shape, specifically, inclined outward from top to bottom in the radial direction of the linking member 130. Therefore, the feeding bin assembly 110 and the transmission assembly 300 play a role in guiding when moving from the separation state to the combination state, and can be better matched.
The feeding mechanism 100 further comprises a linear drive 120. A linear drive 120 can be connected to the feeding magazine 110 for driving the feeding magazine 110 to move in a straight line. Specifically, the feeding bin 110 is provided with a screw hole 115 extending in the vertical direction, and the feeding mechanism 100 further includes a screw 121. The screw 121 can be connected to the output shaft of the linear drive 120 and is located within the screw hole 115. When the output shaft rotates, the screw 121 can move within the screw hole 115 relative to the feeding bin 110, thereby moving the feeding bin 110 up and down.
The feeding mechanism 100 further includes a fixing bracket 122, a fixing seat 123 and a fixing pressure plate 124. The fixing brackets 122 are located within the storage bin 13 and can be connected to the storage bin 13, for example, as an example, the inner bottom surface of the storage bin 13 can be provided with upwardly extending studs (not shown), the fixing brackets 122 can be spaced apart with screw bosses 126 having through holes through which screws can be tightened to the studs, whereby the fixing brackets 122 can be mounted to the storage bin 13. The stationary bracket 122 can be provided with a receiving cavity with a downward opening, and the linear drive device 120 is connected to the stationary bracket 122 and located in the receiving cavity. Specifically, the linear driving device 120 is located in the cavity of the fixing base 123, and the fixing base 123 is accommodated in the receiving cavity. The cavity is adapted to the shape of the linear drive 120 to limit the rotational and vertical movement of the linear drive 120. The fixed pressure plate 124 is located at the opposite side, i.e., the lower side, of the linear driving device 120 from the fixed base 123. The fixed pressing plate 124 may be connected to the fixing base 123, for example, the fixed pressing plate 124 and the fixing base 123 are provided with screw holes, the fixing bracket 122 is provided with screw posts 127 extending downward, and screws are passed through the screw holes of the fixed pressing plate 124 and the fixing base 123 and locked to the screw posts 127. The end of the screw 121 is clamped between the fixed pressing plate 124 and the fixed seat 123.
An outlet of the storage bin 13 may be formed between the bottom of the fixed bracket 122 and the inner bottom surface of the storage bin 13. The outlet is located at one side of the fixed bracket 122. The fixing bracket 122 is provided with an outlet sealing member 125 at a side corresponding to the outlet. The outlet seal 125 can abut the side wall of the feed bin 110 to prevent material from entering the feed mechanism 100. The fixed bracket 122 is further provided with guide posts 128 at intervals extending in the vertical direction. The top of the feeding bin 110 is provided with guide protrusions 116 at intervals, and the guide protrusions 116 protrude from the side walls of the feeding bin 110. The guide projections 116 are located between the spaced apart guide posts 128 and are movable along the guide posts 128 to prevent the feed magazine 110 from shifting during movement.
The wash tank assembly 200 further comprises a wash tank fitting 230 and a mounting 240. The wash bin fittings 230 may be connected to the mounting 240. Part or all of the mounting seats 240 may be provided to the washing tub main body 210 movably in a straight line. In the illustrated embodiment, the partial mount 240 is linearly movable. The stirring piece 19 is located in the washing material cavity 211 and is connected to the mounting seat 240, and the stirring piece 19 is rotatable with the mounting seat 240 relative to the washing material bin main body 210 around a first rotation axis Ax 1. The magazine cover 270 may be provided to the mounting base 240 and may be linearly movable along with the mounting base 240. The mount 240 is rotatable relative to the wash hopper body 210 about a first axis of rotation Ax 1. The transmission assembly 300 includes a transmission body 310 and a wash bin driver 320. The transmission body 310 is rotatable relative to the wash hopper body 210 about a second axis of rotation Ax 2. The transmission body 310 can be engageable with the feed bin 110 and rotatable relative to the feed bin 110. The tub driving member 320 is provided to the driving body 310, and may be mounted to the driving body 310 by, for example, a screw coupling or the like.
There may be a magnetic force between the wash bin fittings 230 and the wash bin drive 320. When the transmission body rotates, the mounting seat 240 and the stirring piece 19 thereon rotate under the action of magnetic force; and when the magnetic force between the wash hopper fitting 230 and the wash hopper drive 320 is changed, the mount 240 moves in a straight line to open and close the wash hopper cover 270.
Wherein the first position may be a non-actuated position including an initial position; the second position may be a drive position and include a first drive position and a second drive position. Further, when the transmission body 310 is located at the first position, the wash hopper driving member 320 is disengaged from the wash hopper fitting member 230. When the transmission body 310 is in the second position, the wash hopper drive 320 is coupled with the wash hopper fitting 230. It should be noted that, for ease of understanding, fig. 3 and 7 show a transitional state during the action, in which the mounting seat 240 provided with the tub cover 270 is unbalanced in force.
The washing bin assembly 200 and the transmission assembly 300 form a contactless transmission therebetween. When the washing is performed in the washing chamber 211, the washing water exists in the space isolated from the driving assembly 300 without contacting the driving assembly 300. Thereby, the contamination of the driving assembly 300 by the wash water can be prevented. Compared with a mechanical transmission mode, the non-contact transmission mode does not need to clean the transmission structure, and the experience of a user can be improved.
In this embodiment, the feeding bin 110 and the transmission assembly 300 can generate a stroke of synchronous movement, and the transmission assembly 300 and the washing bin cover 270 can generate a matching movement, so that only one driving device for driving the feeding bin 110 to move can be arranged, and three linear movements of the feeding bin 110, the transmission assembly 300 and the washing bin cover 270 can be completed, and the movement of the feeding bin 110 and the opening and closing of the discharge opening 212 can be realized. And only one driving device for driving the transmission main body 310 to rotate is arranged, so that the material throwing action during material washing and blanking can be realized.
The wash bin fitting 230 may comprise a translational fitting 231. Translation engagement member 231 is disposed at mount 240. The wash bin drive 320 may comprise a translational drive 321. The translational drive is provided in the transmission body 310. Both the translational drive member 321 and the translational mating member 231 are magnetic members, and a magnetic force may exist between the two. When the state of the translational drive member 321 is changed to change the magnetic force between the translational engagement member 231 and the translational drive member 321, the wash hopper cover 270 moves between an open position to open the discharge opening 212 and a closed position to close the discharge opening 212. The transmission assembly 300 and the wash bin cover 270 are capable of cooperating movement by magnetic action. When the transmission body 310 is moved, the washing bin cover 270 may be opened and/or closed by a magnetic force, so that the discharge opening 212 may be opened and closed.
In one embodiment, the wash bin cover 270 moves from the open position to the closed position when changing the state of the translational drive 321. Thus, the closure of the magazine lid 270 can be achieved by means of the magnetic force between the translational fitting 231 and the translational drive 321. In another embodiment, the wash bin cover 270 moves from the closed position to the open position when changing the state of the translational drive 321. Thus, opening of the magazine lid 270 can be achieved by means of the magnetic force between the translational fitting 231 and the translational drive 321. In the illustrated embodiment, when changing the state of the translational drive 321, the magazine lid 270 moves from the open position to the closed position and from the closed position to the open position. Thus, the opening and closing of the washer magazine cover 270 can be simultaneously achieved by means of the magnetic force between the translation fitting 231 and the translation driving member 321.
The wash tank fitting 230 may include a spin fitting 232. The wash hopper drive 320 may include a rotary drive 322. The rotation fitting 232 is provided to the mount 240. The rotary drive member is disposed on the transmission body 310, and the rotary drive member and the rotary mating member 232 are magnets. When the transmission body 310 rotates, the stirring member 19 rotates by the magnetic force between the rotary driving member and the rotary fitting member 232. Thus, when the driving body 310 is rotated with the washing tub cover 270 opened and closed, washing and blanking actions can be performed.
The magnetic member may include at least one of a magnet, an electromagnet, iron, nickel, cobalt, a ferritic steel, a martensitic steel, and an austenitic-ferritic dual phase steel. Alternatively, the magnet may be a permanent magnet. Alternatively, at least one of the translation fitting 231 and the translation drive 321 may be a magnet. For example, translation fitting 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 translation fitting 231 and the translation driving member 321 are both magnets, whereby a large magnetic force can exist between the translation fitting 231 and the translation driving member 321 and the state is stable. As another example, the translation engagement members 231 are iron, nickel, cobalt, ferritic steel, martensitic steel, austenitic-ferritic dual phase steel, and the translation drive member 321 is a magnet. Because the magnetism of iron, nickel, cobalt, ferrite steel, martensite steel and austenite-ferrite dual-phase steel is not affected by high temperature, the magnetism of the translation fitting 231 can be prevented from being affected by high temperature during cooking, and the performance of the translation fitting can be kept unchanged. Optionally, at least one of the translational engagement element 231 and the translational drive element 321 is an electromagnet.
When the silo cover 270 and the stirring element 19 are both disposed on the same mounting seat 240, the translational engagement element 231 and the translational drive element 321 are not selected to be electromagnets, considering that the rotation of the mounting seat 240 would cause the electric wire to be wound. When the washing bin cover 270 and the stirring member 19 are disposed on different mounting seats 240, the opening and closing 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 to be electromagnets.
For embodiments that do not include electromagnets, the drive assembly 300 is linearly movable relative to the wash bin body 210. When the transmission assembly 300 is moved to change the magnetic force between the translational engagement member 231 and the translational drive member 321, the wash hopper cover 270 is moved between an open position to open the discharge opening 212 and a closed position to close the discharge opening 212. For the illustrated embodiment, by controlling the position of the driving assembly 300 to move up and down, the movement direction of the washing bin cover 270 is controlled to move to the open position and the closed position according to the direction change of the resultant force of the magnetic force and the gravity.
For the electromagnet embodiment, the wash bin cover 270 can move linearly to open and close the discharge opening 212 when the energization state of the electromagnet is changed.
Depending on design requirements, the rotary drive 322 may be located radially outward of the rotary engagement element 232 in the drive position. Alternatively, the rotary drive 322 may be located radially inward of the rotary fitting 232 when in the drive position. Alternatively, the rotary drive 322 may be located above the rotary fitting 232 in the drive position.
The washing bin assembly 200 is located below the driving assembly 300, and the feeding bin 110, the washing bin cover 270 and the driving assembly 300 can move up and down. The translational drive member 321 and the translational mating member 231 are vertically corresponding and have opposite or same magnetic poles facing each other. When the magnetic poles are opposite, the magnetic force between the translational driving piece 321 and the translational matching piece 231 is magnetic attraction, and the washing bin cover 270 moves through the magnetic attraction; when the magnetic poles are the same, the magnetic force between the translational driving member 321 and the translational mating member 231 is a magnetic repulsive force, and the material washing bin cover 270 is moved by the magnetic repulsive force. For the illustrated embodiment, the magnetic poles of the translational drive element 321 and the translational mating element 231 are opposite to each other, and the magnetic force therebetween is a magnetic attraction force.
As shown in fig. 9, the driving body 310 is configured in a dial shape and includes a driving top wall 311 and a driving side wall 312 connected to the driving top wall 311. The transmission side wall 312 extends vertically, the translational driving member 321 is disposed on the transmission top wall 311, and the rotary 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, fastening, and in-mold injection. The translation drive 321 in the illustrated embodiment is removably mounted to the transmission body 310 by fasteners, such as screws.
The height of the transmission body 310 in the first driving position is lower than that in the second driving position. Further, the first driving position is located above the second driving position. When the transmission body 310 is located at the first driving position, the translational driving element 321 and the translational mating element 231 may be linked, and the rotational driving element 322 and the rotational mating element 232 may be linked. When the transmission body 310 is located at the second driving position, the translational driving element 321 is disengaged from the translational mating element 231, and the rotational driving element 322 is engaged with the rotational mating element 232. For the illustrated embodiment, referring to fig. 8, when the transmission body 310 is in the second driving position, the magnetic force between the translational drive member 321 and the translational mating member 231 is smaller than the gravity of the washing bin cover 270 and the first mounting seat 220 and the stirring member 19 connected thereto. Whereby the wash bin cover 270 may be maintained in an open position.
In the illustrated embodiment, the wash bin fitting 230 can be located outside the wash chamber 211, i.e. both the rotary fitting 232 and the translational fitting 231 are located outside the wash chamber 211. The rotary drive member 322 is located radially outward of the rotary engagement member 232 when the transmission body 310 is in the first drive position and the second drive position. Therefore, the structure inside the material washing cavity 211 can be simplified, the volume of the material washing cavity 211 is increased, the single treatment capacity of the washing material is improved, and the washing of the material washing cavity 211 is facilitated. In other embodiments not shown, both the rotating fitting 232 and the translational fitting 231 are located inside the wash chamber 211. When the rotary drive 322 is in the drive position, i.e. when the transmission body 310 is in the first drive position and the second drive position, the rotary drive 322 is located radially inside the rotary counterpart 232. Therefore, the cooking utensil has a simple external structure and is beneficial to product miniaturization; and the structure of the driving assembly 300 may be simpler. As an example, a cylindrical mounting seat may be included inside the wash chamber 211, to which the wash bowl cover 270 and the agitation member 19 may be both attached. A rotation fitting 232 and a translation fitting 231 are provided in the mount. The washing bin main body 210 is provided with a trough portion located inside the washing cavity. The slot portion forms a receiving slot to receive the translation drive member 321 and the rotation drive member 322, more particularly the transmission body.
The structure of the wash bin assembly 200 of the present embodiment is described below with reference to fig. 12A to 16.
As shown in fig. 12A and 13, mount 240 includes first mount 220 and second mount 250 connected to first mount 220. The first mount 220 is located radially inward of the second mount 250 and is linearly movable with respect to the second mount 250. The stirring member 19, the washing bin cover 270 and the movable fitting member 231 may be provided to the first mounting seat 220. The rotation fitting 232 may be provided to the second mounting seat 250. First mount 220 may rotate with second mount 250.
The first mount 220 may include a mount base 221 and a mount barrel 222 connected to the mount base 221. The agitator 19 and the wash bowl cover 270 are provided to the mount base 221. The mounting seat cylinder portion 222 is located at the radial outer side of the material washing cavity 211, and the bottom thereof is provided with seat openings 224 at intervals along the circumferential direction, so that the material falls into the inner pot 3 through the seat openings 224 when falling. The translation engagement element 231 is disposed on top of the mount barrel portion 222 such that there is a small distance between the translation engagement element 231 and the translation drive 321, which generates a magnetic force large enough to move the wash chamber lid 270 up and down.
The wash bin assembly 200 also includes a bin body base 217. The cartridge body base 217 is located below the wash cartridge body 210 and is detachably connected thereto, such as by a fastening connection, to the wash cartridge body 210. The second mount 250 is supported on the cartridge body base 217 below it. The rotation fitting 232 may be disposed on an outer circumferential surface of the second mounting seat 250 extending in the vertical direction, so that there may be a small distance in the radial direction between the rotation fitting 232 and the rotary driving member 322, and a sufficient magnetic force can be generated to rotate the mounting seat 240. The rotary drive 322 and the rotary engagement member 232 may be provided in plurality and as block members. A plurality of rotary drives 322 are spaced circumferentially along the transmission body 310. A plurality of rotation fittings 232 are arranged at intervals along the circumference of the second mount 250.
When the transmission assembly 300 is in the drive position, the projection of the rotary drive element 322 onto the plane parallel to the axial direction overlaps with the projection of the rotary counterpart 232. When the transmission assembly 300 is located at the first driving position, the projection of the rotary driving element 322 and the rotary matching element 232 on the plane parallel to the axial direction has a first overlapping area. When the transmission assembly 300 is located at the second driving position, the projection of the rotary driving element 322 and the rotary matching element 232 on the plane parallel to the axial direction has a second overlapping area. The first overlap area may be greater than the second overlap area. The plurality of rotary drive members 322 and the plurality of rotary engagement members 232 may be arranged in one or two rows in the axial direction. For example, as shown in fig. 9 and 13, the rotary driving element 322 and the rotary fitting element 232 may be arranged in a row in the axial direction, and both may be configured in a long bar shape, i.e., as long bar-shaped members. The rotary drive 322 is positioned horizontally and the rotary engagement member 232 is positioned vertically.
The cartridge body 210 may further comprise a cartridge body top wall 216, an inner sidewall 214 and an outer sidewall 215 (fig. 14) connected to the cartridge body top wall 216, which three constitute the above-mentioned sidewall portion 6. The inner sidewall 214 is radially inward of and radially spaced from the outer sidewall 215. The inner sidewall 214 encloses a wash chamber 211. The second mount 250 and the mount barrel portion 222 are located between the inner sidewall 214 and the outer sidewall 215. One of the first and second mounting seats 220 and 250 may be provided with a seat guide groove 223, the seat guide groove 223 extending in the axial direction, and the other of the first and second mounting seats 220 and 250 may be provided with a seat guide portion 251, the seat guide portion 251 being located within the seat guide groove 223 and linearly movable with respect 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, the first mounting seat 220 can rotate together with the second mounting seat 250 on one hand, and the first mounting seat 220 can keep moving along a straight line on the other hand, so that the displacement is avoided.
The wash bin assembly further comprises a support member. The supporting member is provided to the washing bin main body 210. The support member is provided with an upwardly facing seat retaining surface 252 for upwardly supporting the mounting seat 240. In the present embodiment, the support member includes the second mount 250 and the cartridge body base 217. The second mounting seat 250 is provided with a seat stopper surface 252 facing upward for supporting the first mounting seat 220 upward. The cartridge body base 217 supports the first mount 220 upward. Fig. 15 shows that the mount socket cylinder portion 222 is provided with the socket guide groove 223, and the second mount socket 250 is provided with the socket guide portion 251. The top surface of the seat guide 251 is a seat stopper surface 252. In an embodiment not shown, the second mount 250 is provided with a mount guide groove 223 and the mount drum portion 222 is provided with a mount guide portion 251. The bottom surface of the seat guide groove 223 is a seat stopper surface 252.
Alternatively, the mount cartridge 222 can include an upper cartridge portion and a lower cartridge portion. The upper part of the cylinder part protrudes outwards from the lower part of the cylinder part in the radial direction, namely the thickness of the upper part of the cylinder part is larger than that of the lower part of the cylinder part. The seat guide groove 223 may be provided at an upper portion of the cylinder portion and the seat opening 224 is provided at a lower portion of the cylinder portion.
As shown in fig. 12A, 16 and 16A, the washing bin assembly 200 further includes a port seal 261 to prevent water leakage during the washing operation. The port seal 261 can be provided on the outer circumferential portion of the washer bin cover 270 so as to move up and down together with the washer bin cover 270. When the wash silo cover 270 is in the closed position, the material port seal 261 abuts the wash silo body 210 at the discharge port 212. Thereby, the wash bowl cover 270 is pressed against the first mounting seat 220 and the agitator 19 to be not rotated. When the washing bin cover 270 is located at the closed position, the material port sealing member 261 can seal the gap between the washing bin cover 270 and the washing bin main body 210, so that the washing water is prevented from leaking from the gap during washing. When the washing bin cover 270 is in the closed position and the stirring piece 19 rotates, the washing bin cover 270 remains stationary relative to the washing bin main body 210, i.e., remains in a constant relative position to the washing bin main body 210 and does not rotate with the stirring piece 19. The sealing effect of the sealing element 261 of the material port can be better, the cover of the material washing bin cover 270 is tighter, and the water leakage is avoided.
The wash tub cover 270 is disposed on a side of the mount base 221 facing the wash chamber 211, specifically, an upper side of the mount base 221. The mount base 221 is rotatable relative to the wash bin cover 270. The outer circumferential portion of the washer bin cover 270 may be provided with a cover recess 273 recessed radially inward. The lid recess 273 has a ring shape. A portion of the gate seal 261 can be located within the lid recess 273.
In one embodiment, as shown in the illustrated embodiment, the gate seal 261 may be located below the washer hopper body 210. The wash bin cover 270 can have a cover support surface 271. The cover supporting surface 271 faces the side of the discharge opening 212, specifically, upward.

As shown in fig. 6, 8, 21, and 22, the first rotational axis Ax1 can be collinear with the second rotational axis Ax 2. The wash chamber 211 is configured to be centrosymmetric, for example, the wash chamber 211 may be cylindrical in shape. The central axis of the wash chamber 211 is collinear with the first axis of rotation Ax 1. The first axis of rotation Ax1 and the second axis of rotation Ax2 may each extend vertically. The central axis of the wash chamber 211 may also extend vertically. The rotation fitting 232 may be provided in plurality at intervals in the circumferential direction of the mount 240, and particularly, at intervals in the circumferential direction of the second mount 250. The rotary drive members 322 are provided in plurality at intervals along the circumferential direction of the transmission body 310. The plurality of rotating engagement members 232 are equally magnetic and are arranged symmetrically about the first axis of rotation Ax 1.

The plurality of rotating matching pieces 232 are uniformly arranged along the circumferential direction of the mounting seat 240; the plurality of rotary driving members 322 are uniformly arranged along the circumferential direction of the transmission body 310. Thus, the magnetic force applied to the second mounting seat 250 in the circumferential direction can be equal in magnitude and uniform in force, so that the first rotation axis Ax1 and the second rotation axis Ax2 can be kept collinear. The magnetic properties of the plurality of rotation fittings 232 may also be different, but the number of different magnetic rotation fittings 232 is equal. Preferably, the rotating engagement members 232 with different magnetic properties are also uniformly and alternately arranged on the premise of equal number, for example, a set of first magnetic rotating engagement members is arranged first, then a set of another magnetic rotating engagement member is arranged, then a set of first magnetic rotating engagement members is arranged, then a set of second magnetic rotating engagement members is arranged, such repeated arrangement at intervals ensures that the magnetic properties of two adjacent sets of rotating engagement members are different but the number of the rotating engagement members is the same, the number of the magnets in each set is the same, and is greater than or equal to 1, and specifically, the number can be flexibly arranged as required, for example, the number can be two, three, four, five or six, and the like. For example, the total number of the rotation fitting members 232 may be two and uniformly arranged, wherein one magnet faces outward to form an N-pole, and the other magnet faces outward to form an S-pole. Two rotary drives can be provided for this purpose. Or as shown in fig. 22, there are 4 sets of rotating mating parts, each set has 3 magnets, the outward magnetic poles of one set of 3 magnets can be all set as N poles, and the outward magnetic poles of the adjacent set of 3 magnets can be all set as S poles, so that the outward magnetic poles of the rotating mating parts are NNN, SSS, respectively. Correspondingly, the magnetic properties of the plurality of rotary driving members 322 engaged therewith also need to be different, but the number thereof needs to be equal and the same and spaced apart. For example, as shown in fig. 22, the number of the rotary drive members is 16, and the rotary drive members may be set to 4 groups, wherein the outward magnetic poles of one group of 4 magnets are all set to N poles, and the outward magnetic poles of the adjacent 4 magnets are all set to S poles, so that the outward magnetic poles of the rotary drive members are NNNN, SSSS, NNNN and SSSS, respectively. When the magnetic bearing rotates, the outward magnetic poles are matched by the rotary driving piece with the NNNN group and the rotating mating piece with the outward magnetic poles as the SSS group to generate magnetic force, and the outward magnetic poles are matched by the rotary driving piece with the SSS group and the rotating mating piece with the outward magnetic poles as the NNN group to generate magnetic force. Thus, the magnetic force applied to the second mounting seat 250 in the circumferential direction can be equal in magnitude and uniform.
The wash bin assembly 200 may also include a spacing member. The mount 240 rotates about the stopper member, which abuts against the mutually opposing surfaces of the mount 240.

At this time, the magnetic force between the rotary driving member 322 and the rotary engaging member 232 is a magnetic attraction force, and the stirring bar 19 is rotated by the magnetic attraction force. As shown in fig. 22, the rotary drive 322 is arranged offset in the radial direction from the rotary counterpart 232 in the drive position and has the same magnetic polarity facing each other. At this time, the magnetic force between the rotary driving member 322 and the rotary engaging member 232 is a magnetic repulsive force, and the stirring bar 19 is rotated by the magnetic repulsive force.

The whole washing operation of the cooking appliance 1 of the present embodiment is described below with reference to fig. 2 to 8:
as shown in fig. 2, the cooking appliance 1 is in an initial state. At this time, the feeding bin 110 and the transmission assembly 300 are both in the initial position of the first position, the feeding bin 110 is not communicated with the outlet of the storage bin 13 and the feeding port 201 of the washing bin assembly 200, and the washing bin cover 270 is in the open position. In the initial state, the force relationship of the washing bin cover 270 is F1< G1+ G2, wherein F1 is the magnetic force between the translational fitting 231 and the translational driving element 321; g1 is the total weight of the washer magazine cover 270 and the follower load that moves linearly with it, which in this embodiment includes at least the first mount 220, the translation mating piece 231 and the stirring piece 19; g2 is the weight of water and material in the wash chamber 211. It is understood that G1 is a fixed value and F1 and G2 are variable values. In this state, F1 is at a minimum Fmin, and may even be close to or equal to 0, G2 is 0, or G2 is the weight of the small amount of residual water left after washing on the wash chamber 211.
When the blanking operation is intended, firstly, the linear driving device 120 can drive the screw rod 121 to move, so that the screw rod 121 can drive the feeding bin 110 to move downwards to the first driving position in the second position, and then the transmission assembly 300 also moves downwards to the first driving position in the second position, as shown in fig. 3, the cooking utensil is in the first state of preparation for blanking. At this time, the outlets of the feeding bin 110 and the storage bin 13 and the feeding port 201 of the washing bin assembly 200 are not communicated, and in the process, F1 is increased; in the state shown in fig. 3, the force relationship of the washing bin cover 270 is F1> G1+ G2, wherein G2 is the same as in the initial state. Due to F1> G1+ G2, the washer bin cover 270 is unbalanced in force and cannot be kept in the open position to move upward to the closed position under the action of magnetic force. As shown in fig. 4, the wash bin cover 270 has been in the closed position and the discharge opening 212 has been closed. The cooking appliance is quickly switched from the state shown in fig. 3 to the state shown in fig. 4, i.e. the lid 270 is moved upwards to the closed position, and the process F1 continues to increase to F1max, with the force relationship F1> G1+ G2. Where F1 is F1max, where G2 is the same as in the initial state.
It is understood that water may be supplied to the material washing chamber 211 in the state of fig. 4, that is, water may be supplied to the material washing chamber before the material is fed. Clean water in the clean water tank 81 enters the feeding bin 110 through the pipeline and the water inlet 113 and then enters the washing cavity 211 through the water outlet 114. When water supply is selected in the state of fig. 4 and the water supply is completed, the force relationship of the washing bin cover 270 is F1> G1+ G2, wherein F1 is F1max and G2 is the weight of water.
The feeding bin 110 then continues to move downward into the wash chamber 211 without the drive assembly 300 moving therewith. Now, as shown in fig. 5, the feeding bin 110 is at the additional position, the transmission assembly 300 is at the first driving position in the second position, the feeding bin 110 is communicated with the outlet of the storage bin 13 and the feeding port 201 of the washing bin assembly 200, and the washing bin cover 270 is still at the closed position. The material in the storage bin 13 enters the feeding bin 110 through the feeding hole 111, and then enters the washing cavity 211 through the discharging hole 112, so as to perform the discharging operation. In this state, solid materials such as rice, millet, corn kernels, black beans, red beans and mung beans can be conveyed into the material washing cavity 211 through the feeding bin 110. The amount of the material flowing into the washing chamber 211 can be calculated by time, and the cooking appliance controls the time of the feeding bin 110 at the additional position according to the amount of the material required by the user, so as to realize quantitative blanking.
Alternatively, water may be supplied to the material washing chamber 211 in the blanking state, or both blanking and water supply may be performed, or the water supply operation may be performed after blanking. Clean water in the clean water tank 81 enters the feeding bin 110 through the pipeline and the water inlet 113 and then enters the washing cavity 211 through the water outlet 114. When the blanking and the water supply are finished, the stress relation of the washing bin cover 270 is F1> G1+ G2, wherein F1 is F1max, and G2 is the weight of water and the materials.
It should be understood that the water supply may be omitted in the states of fig. 4 and 5, that is, only the material is supplied in the state of fig. 5, and the water supply operation is performed in the subsequent state, for example, in the state of fig. 6, however, if no water is supplied in the states of fig. 4 and 5, G2 in the state of fig. 4 is the same as that in the initial state, and G2 in the state of fig. 5 is the weight of the material added in the initial state.
When the blanking is finished or the blanking and water supply are finished, the linear driving device 120 drives the screw rod 121 to move again, and the screw rod 121 drives the feeding bin 110 to move upwards to the first driving position in the second position, as shown in fig. 6, it can be understood that water supply can be performed in a state not shown in fig. 4 and in fig. 5, or in a state shown in fig. 6, for example, water supply before the rotation in fig. 6 or even water supply in the middle of the rotation. In the state shown in fig. 6, the rotation driving device 301 drives the transmission body 310 to rotate, and then the magnetic force between the rotation driving component 322 and the rotation matching component 232 can drive the second mounting seat 250 to rotate, and further drive the first mounting seat 220 and the stirring component 19 thereon to rotate together, so as to perform a material washing operation. It will be appreciated that for the illustrated embodiment, the water level in the wash chamber 211 is below the highest portion of the waste pipe 10 when a wash action is taking place. In other embodiments, not shown, a separate solenoid valve may be provided to open and close the waste outlet 213, and the draining may be directly controlled by directly controlling the open and closed states of the solenoid valve, which may not limit the water level in the wash chamber 211 from having to be lower than the highest portion of the waste pipe.
For the illustrated embodiment, when the washing action is completed and the draining is intended, water is first supplied to the washing chamber 211 until the water level in the washing chamber 211 is higher than the highest portion of the sewage drain pipe 10, and the draining is performed by using the siphon principle. And the highest position of the drain will have a velocity head, thereby creating a full flow of the drain 10. When the water level is lowered to the highest position lower than the sewage pipeline 10, because the drainage channel is already in the full flow state, at this time, because the water level in the washing cavity 211 is higher than the water level of the water outlet 114 of the sewage pipe 107, according to the bernoulli principle, the outlet of the sewage pipe 107 has a speed water head, and the water in the washing cavity 211 can be drained completely. And after washing, draining. When the water drainage is finished, the stress relation of the washing bin cover 270 is F1> G1+ G2, wherein F1 is F1max, and G2 is the weight of the water absorbed material and a small amount of residual water. If necessary, clear water can be added into the material washing cavity 211 after water is drained for cooking; in this case, G2 is the weight of the absorbed material and the clear water. The actions of water supply, material washing and water drainage can be repeatedly executed, and multiple material washing of single material is realized.
When the discharging action is completed and the blanking is intended, the linear driving device 120 drives the feeding bin 110 to move upwards to the second driving position of the second position, as shown in fig. 7. In the state shown in fig. 7, the force relationship of the washing bin cover 270 is F1< G1+ G2, wherein F1 is reduced, i.e. F1< F1max, G2 is the same as when the draining is completed, and G2 also contains the weight of the added fresh water if the fresh water is added after the draining in the state of fig. 6. Due to F1< G1+ G2, the washer bin cover 270 is unbalanced in force and cannot be kept in the closed position to move downward. The cooking appliance is quickly switched from the state shown in fig. 7 to the state shown in fig. 8, as shown in fig. 8, the wash bin cover 270 is already in the open position, and the discharge opening 212 is already open. At this time, part of the materials or part of the materials and water fall into the inner pot 3, and G2 is reduced. In the state shown in fig. 8, the force relationship of the washing bin cover 270 is F1< G1+ G2, wherein F1< F1max and G2 are the weight of the residual water-absorbing material and the small amount of residual water. At this moment, the rotary driving device 301 can drive the transmission main body 310 to rotate again, so that the stirring piece 19 rotates to start throwing the material, and the material falls into the inner pot 3 quickly under the action of centrifugal force. G2 is continuously reduced during material throwing, and after the material throwing is finished, the force bearing relation of the washing bin cover 270 is F1< G1+ G2, wherein F1< F1max and G2 are the weight of a small amount of residual water. As an example, the difference between F1 and G1+ G2 at this time may be 30G. Except that can add the clear water behind the drainage of figure 6, also can select to add clear water in the state of figure 8, for example can be before throwing the material or after throwing the material, can add the clear water even in throwing the material midway, can set up in a flexible way as required. After being added to the washing chamber 211, the clean water is input into the inner pot 3 through the discharge opening 212 for subsequent cooking.
Each action in the process from blanking to blanking can be repeatedly executed, and multiple times of material washing can be realized; that is, the respective states shown in fig. 3 to 8 are repeatedly executed. That is, after the state shown in fig. 8, the linear driving device 120 drives the feeding bin 110 to move upward to the first driving position of the second position, that is, to the position shown in fig. 3. And then, repeatedly executing the states shown in the figures 3 to 8 until the material washing and blanking of the materials for multiple times are completed.
Then, after finishing the blanking and water adding actions, the following actions can be carried out.
One solution is to close the washing bin cover 270 first. I.e. the cooking appliance is switched from the state described in fig. 8 to the state shown in fig. 4. Moving the feeding bin 110 and the transmission assembly 300 to the first driving position to move the washing bin cover 270 to the closed position shown in fig. 4, in the process, the force relationship of the washing bin cover 270 is F1> G1+ G2, wherein F1 is F1max, and G2 is the weight of a small amount of residual water, so that the washing bin cover 270 is unbalanced in force and cannot be kept in the open position, and thus moves upward to the closed position, at which time, the steam inlet 202 is closed, and the cooking cavity between the pot cover 4 and the pot body 2 is closed. During cooking, the washing bin cover 270 is closed, so that heat cannot be greatly taken away by the steam inlet 202, the early-stage rapid temperature rise of the cooking cavity can be realized, and the cooking speed is accelerated.
It can be understood that the venting operation may be performed during cooking, that is, the cooking appliance may be switched from the state shown in fig. 4 to the state shown in fig. 2 or fig. 7, that is, the feeding bin 110 and the transmission assembly 300 are moved upward, and during this process, the force relationship of the washing bin cover 270 is F1< G1+ G2, so that the washing bin cover 270 is unbalanced in force and cannot be maintained in the closed position, and therefore, is moved downward to the open position. At the moment, because a separate steam valve is eliminated, the structure of the pot cover 4 is facilitated to be simplified, the production and the manufacture are facilitated, and the product miniaturization is facilitated. After the air exhausting action is completed, the washing bin 270 may be closed, i.e. switched to the state shown in fig. 4, or the washing bin 270 may not be closed, and the state shown in fig. 2 or fig. 8 may be remained. Finally, after cooking is completed, the cooking appliance will maintain the state shown in fig. 2 or switch to the state shown in fig. 2, i.e. the positions of the feeding bin 110 and the transmission assembly 300 are maintained or moved to the initial position, so that the washing bin cover 270 is in the normally open position.
It can be understood that the gas may not be exhausted during cooking, and the reset operation is performed only after cooking is completed, that is, after cooking is completed, the state of the cooking appliance is switched to the state shown in fig. 2, that is, the feeding bin 110 and the transmission assembly 300 are moved upward to the initial position. In the process, the force relationship of the washing bin cover 270 is F1< G1+ G2, so that the washing bin cover 270 is unbalanced in force and cannot be maintained in the closed position, and thus moves downward to the open position. Namely, the reset of the feeding bin 110, the transmission assembly 300 and the washing bin cover 270 is completed. This kind of scheme can guarantee the heat preservation effect of culinary art intracavity, and can avoid the foam to overflow when water boils and wash in the material chamber 211, makes the culinary art after, washes stains such as residual starch in the material chamber 211, and the influence user uses and experiences.
Alternatively, after the state shown in fig. 8, the reset operation is performed directly, that is, the cooking utensil is switched from the state shown in fig. 8 to the state shown in fig. 2, that is, the feeding bin 110 and the transmission assembly 300 are moved upward to the initial position for reset. Since the discharge opening 212 is opened, the washing chamber 211 can serve as a steam passage when cooking. Therefore, a separate steam valve can be omitted, which is beneficial to simplifying the structure of the pot cover 4, facilitating the production and manufacture and being beneficial to the miniaturization of products.
It will be appreciated that the discharge opening 212 may be closed at any time during cooking, and that when it is desired to close the discharge opening 212, the wash hopper cover 270 may be moved upwardly and close the discharge opening 212 by simply moving the feed hopper 110 and drive assembly downwardly to the position of fig. 3. It will be appreciated that the discharge opening 212 may be opened as desired after closing the discharge opening during cooking, and that the wash bin cover 270 may be moved downwardly and close the discharge opening 212 when it is desired to open the discharge opening 212 by simply moving the feed bin 110 and drive assembly upwardly to the position of FIG. 7, or upwardly to the position of FIG. 2.
Finally, after cooking is completed, the cooking appliance will maintain the state shown in fig. 2 or switch to the state shown in fig. 2, i.e., the positions of the feeding bin 110 and the transmission assembly 300 are maintained or moved to the initial position, so that the washing bin cover 270 is in the normally open position.
