This scheme makes stirring piece 19 rotate the in-process, and the material on it except having the effect of centrifugal force, the inclined surface can also make the material throw away more easily to the inclined surface still is convenient for the material and slides downwards, can reduce the residual material in washing material chamber 211.

Transmission assembly

In one embodiment, the cooking appliance 1 further comprises a transmission assembly 300, the transmission assembly 300 being linearly movable. Specifically, the drive assembly 300 can be engageable with the feed bin 110 to move the drive assembly 300 with the feed bin 110 between a first position (as shown in fig. 2) and a second position (as shown in fig. 3). The transmission assembly 300 can drive at least one part of the washing bin assembly 200 to rotate, for example, at least to rotate the stirring piece 19, so as to complete the material throwing process during material washing and/or material falling; and can drive the stirring piece 19 and the washing bin cover 270 to move between the opening position and the closing position together so as to complete the processes of blanking and draining.

The drive assembly 300 is disposed in the magazine or feed mechanism 100. In particular, the transmission assembly 300 is not provided on the lid 4. This scheme is through setting up electrified transmission assembly 300 in the position department outside pot cover 4, can reduce the part on the pot cover 4, and the pot cover structure is simpler, can convenience of customers to the washing operation of pot cover 4 and washing feed bin subassembly 200 simultaneously to this scheme can be so that need not to consider transmission assembly 300's waterproof at the manufacturing stage of pot cover 4, thereby has simplified manufacturing process.

The above-mentioned storage mechanism, feeding mechanism 100, transmission assembly 300 and washing bin assembly 200 form part of the washing system of the present embodiment.

The following describes the transmission structure among the feeding mechanism 100, the transmission assembly 300 and the washing bin assembly 200 in detail with reference to the accompanying 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 as being normally closed.

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. 4, 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 bin 110 moves away from the drive assembly 300. The feeding bin 110 can be moved from the second position to additional positions and from the additional positions to the second position so that the feeding bin 110 can enter or leave the wash chamber 211 to facilitate the blanking and terminate the blanking.

The wash tank assembly 200 is located below the driving 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 drive 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. 10-12, the feed 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 connection structure 117, the link 130 is provided with a structure cooperating with the rotary connection structure 117, and the link 130 is rotated to be connected to the rotary connection 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 body central bore 313.

The link 130 is located at a lower side of the transmission body 310 and is provided with a link support surface 131 facing upward for supporting the transmission assembly 300 upward. The feed bin 110 can drive the transmission assembly 300 to move upwards by means of the linkage supporting surface 131. For the illustrated embodiment, the drive 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. The linear driving device 120 can be connected to the feeding hopper 110 for driving the feeding hopper 110 to move linearly. 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 an 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 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 base 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 platen 124 may be connected to the fixed base 123, for example, the fixed platen 124 and the fixed base 123 are provided with screw holes, the fixed bracket 122 is provided with downwardly extending screw posts 127, and the screw passes through the screw holes of the fixed platen 124 and the fixed base 123 and is locked to the screw posts 127. The end of the screw 121 is clamped between the fixed platen 124 and the fixed base 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 wall 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 the 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 unit 320 is provided to the driving body 310, and may be mounted to the driving body 310 by means of, for example, a screw coupling or the like.

There may be a magnetic force between the washer bin adaptor 230 and the washer bin driver 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 driving member 320 is changed, the mounting seat 240 moves in a straight line to open and close the wash hopper cover 270.

Transmission body 310 has a non-driving position (e.g., different blanking states shown in fig. 6 and 7) for disengaging the washer bin mating element 230 from the washer bin driver 320, and a driving position for engaging the washer bin mating element 230 with the washer bin driver 320. Wherein the drive positions include a first drive position (e.g., the respective states shown in fig. 3-5) and a second drive position (e.g., the blanking state shown in fig. 8). The first driving position corresponds to a closed position, the second driving position corresponds to an open position, and the non-driving position may be an open position (different blanking states as shown in fig. 6 and 7) or a closed position (e.g., the initial position of fig. 2), although in other embodiments, the initial position may be set to the open position.

Wherein the first position may be a non-driving position including an initial position and an intermediate position (different blanking states as shown in fig. 6 and 7); 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 washing bin driving member 320 is disengaged from the washing bin fitting member 230. When the transmission body 310 is located at the second position, the washing bin driving member 320 is linked with the washing bin fitting member 230. The intermediate position is located between the initial position and the second drive position. It should be noted that, for ease of understanding, fig. 6 and 9 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. For mechanical transmission mode, contactless transmission mode need not to wash transmission structure, and this can promote user's experience and feel.

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 provided, 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 fittings 230 may include a translation fitting 231. Translation engagement member 231 is disposed at mount 240. The wash bin drive 320 may comprise a translational drive 321. The translation drive is arranged on the transmission main body 310. The translational driving member 321 and the translational mating member 231 are both 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. Thereby, the closing of the washer magazine cover 270 can be achieved by means of the magnetic force between the translation fitting 231 and the translation driving member 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 bin fitting 230 may include a swivel 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 driving member 322 is disposed on the transmission body 310, and the rotary driving member 322 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 322 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, ferrite steel, martensite steel and austenite-ferrite dual-phase steel. One example is that the translation engaging element 231 and the translation driving element 321 are both magnets, whereby a large magnetic force can exist between the translation engaging element 231 and the translation driving element 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 is 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 member 19 are both disposed on the same mounting seat 240, the translational matching member 231 and the translational driving member 321 are not selected to be electromagnets, considering that the rotation of the mounting seat 240 may cause the winding of the electric wire. 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 an electromagnet, 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 moving direction of the washing bin cover 270 is controlled to move to the open position and the closed position according to the 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 is moved 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. 10, the driving body 310 is configured in a turntable 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 arranged on the transmission main body 310 through at least one of clamping, fastener connection and in-mold injection. The translational drive member 321 in the illustrated embodiment is removably mounted to the drive body 310 by fasteners, such as screws.

The transmission body 310 has a lower height in the first driving position than 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 present embodiment, the wash bin fitting 230 can be located outside the wash chamber 211, i.e. the rotation fitting 232 and the translation 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.

The structure of the wash bin assembly 200 of the present embodiment is described below with reference to fig. 13 to 17.

As shown in fig. 13 and 14, 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 mount 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 radially outside the material washing cavity 211, and is provided at a bottom thereof with seat openings 224 at intervals in a 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.

Translational mating element 231 is disposed on mounting base 240 by at least one of snapping, fastening, and injection molding. As shown in fig. 13, the translational engagement member 231 may be pre-embedded in the mounting tube 222, for example, by being molded in the mounting tube 222 through an in-mold injection molding process. Alternatively, in an embodiment not shown, the translation engagement 231 may also be removably mounted to the mount barrel portion 222 by fasteners, such as screws. Specifically, the top surface of the mount drum portion 222 is provided with a mounting groove recessed downward, and the translation fitting 231 is fixed in the mounting groove. The translation fitting 231 may be provided with a plurality of block-shaped members, or provided with one annular member, or the like. For embodiments of multiple translation fittings 231, the multiple translation fittings 231 may be spaced apart along the circumference of the first mount 220, preferably in an annular array.

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 drivers 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 driving position, the projection of the rotary driving element 322 and the rotary fitting 232 on the plane parallel to the axial direction are overlapped. 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 fitting 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 drives 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. 10 and 14, the rotary driving element 322 and the rotary engaging element 232 may be arranged in a row in the axial direction, and each may be configured in a long strip shape, i.e., a long strip-shaped member. The rotary drive 322 is positioned horizontally and the rotary mating element 232 is positioned vertically.

The wash cartridge body 210 may further include a cartridge body top wall 216, an inner sidewall 214 and an outer sidewall 215 (fig. 15) connected to the cartridge body top wall 216, which form the sidewall portion 6 described above. 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 cartridge portion 222 are positioned 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

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 a seat stopper face 252 facing upward for supporting the mount 240 upward. 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. 16 shows that the mount base cylinder portion 222 is provided with the base guide groove 223, and the second mount base 250 is provided with the base 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 barrel portion 222 may include a barrel portion upper portion and a barrel portion lower 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 on an upper portion of the cylinder portion and the seat opening 224 is provided on a lower portion of the cylinder portion.

As shown in fig. 13, 17 and 17A, 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 member 19 rotates, the washing bin cover 270 remains stationary relative to the washing bin main body 210, i.e., remains unchanged from the relative position of the washing bin main body 210, and does not rotate with the stirring member 19. The sealing effect of the material port sealing element 261 can be better ensured, the material washing bin cover 270 is more tightly covered, and the water leakage situation 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 in the illustrated embodiment, the gate seal 261 can be located below the wash hopper body 210. The wash bowl cover 270 can have a cover support surface 271. The cover supporting surface 271 faces the side of the discharge opening 212, specifically, upward. The gate seal 261 can abut against the cover support surface 271 to provide an upward supporting force to the gate seal 261. When the wash cartridge cover 270 is in the closed position, the port seal 261 is sandwiched between the bottom of the wash cartridge body 210 and the cover support surface 271, and the wash cartridge cover 270 is held stationary relative to the wash cartridge body 210 by being pressed downward at the cover support surface 271. In this embodiment, the bottom surface of the sidewall portion 6 and the gate seal 261, and in particular the bottom surface of the inner sidewall 214 and the gate seal 261, may abut. The gate seal 261 is subjected to a downward pressing force. In other embodiments, not shown, the inner surface of the sidewall portion 6 may abut the port seal 261, and the rotation of the washer silo cover 270 may be limited by the friction between the port seal 261 and the sidewall portion 6.

As shown in fig. 17A, the bottom of the wash hopper body 210 is provided with a body arcuate surface 218, and the body arcuate surface 218 is abuttable to the gate seal 261. The contact area between the bottom of the material washing bin main body 210 and the material port sealing piece 261 can be increased, so that the material washing bin main body and the material port sealing piece are more stably abutted, and the sealing effect is better.

The material port sealing member 261 is an annular member and is fitted around the outer periphery of the washer chamber cover 270. The outer circumferential portion of the sump cover 270 may be provided with a cover boss 272 protruding radially outward. The gate seal 261 is disposed on the cover boss 272. The upper surface of the cover projection 272 is a cover supporting surface 271, which can support the washing tub cover 270.

The mount base 221 may be provided with a cover mounting portion 263, and the wash bowl cover 270 may be provided with a cover mounting hole 264. The cover mounting portion 263 can be located in the cover mounting hole 264. A mounting packing 262 is provided between the cap mounting portion 263 and a hole wall of the cap mounting hole 264 to seal a gap between the mount base 221 and the wash bowl cover 270. The cover mounting portion 263 is provided with a radially recessed mounting portion groove 265, and the mounting seal 262 is located in the mounting portion groove 265. An abutment boss is provided in the cover mounting hole 264, the abutment boss being provided with a seat arc surface 274 facing the mounting portion recess 265 to increase the contact area of the mounting seal 262 with the cover mounting hole 264, improving the sealing effect.

The agitation member 19 can be located on the opposite side, specifically the upper side, of the washer tub cover 270 from the mount base 221. That is, the wash bowl cover 270 is located between the agitator 19 and the mount base 221. The stirrer 19 is connected to the cover mounting portion 263. One of the stirring piece 19 and the cover mounting portion 263 may be provided with a coupling protrusion, and the other thereof may be provided with a coupling groove in which the coupling protrusion is located. Fasteners, such as screws, may be connected to the connecting bosses through mount base 221 to connect stirring member 19 to mount base 221. The drawing schematically shows that the stirring piece 19 is provided with a connecting projection, and the cover mounting portion 263 is provided with a connecting recess.

As in the illustrated embodiment, the washer silo cover 270, the mounting base 221, the stirring piece 19 and the material port seal 261 are combined together, and when the washer silo cover 270 is in the closed position, the washer silo cover 270, the mounting base 221, the stirring piece 19 and the material port seal 261 together block the material outlet 212. When the stirring piece 19 and the mounting base bottom 211 rotate together, neither the washing silo cover 270 nor the material opening seal 261 rotate, i.e. the relative position to the washing silo main body 210 remains unchanged. 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.

Alternatively, the discharge opening 212 may be blocked by other means, such as the purge bin cover 270 alone blocking the discharge opening 212, or the purge bin cover 270 may block the discharge opening 212 together with one or more of the seal, the stirring member 19, and the mounting seat. One or more of the sealing member, the stirring member 19, the mounting seat may be moved together with the silo cover 270 in synchronization, i.e. together to open and close the discharge opening 212 together. One or more of the sealing member, stirring member 19, and mounting seat may also be moved separately from the silo cover 270 to open and close the discharge opening 212.

Alternatively, the discharge opening 212 may be blocked only by the wash hopper cover 270, and the discharge opening 212 may be covered only by the wash hopper cover 270. Further, a sealing element can be arranged between the washing bin cover 270 and the washing bin main body, the discharge opening 212 is sealed and blocked by the washing bin cover 270 and the sealing element, and the sealing element can be arranged on the washing bin cover 270 or the washing bin main body.

Optionally, the discharge opening 212 is sealed by the washer bin cover 270 and a portion of the mounting seat, and further, a sealing member may be further included, and the washer bin cover 270, a portion of the mounting seat and the sealing member together seal the discharge opening 212. Seals may be provided on one or more of the wash hopper cover 270, a portion of the mounting base, and the wash hopper body to better seal the discharge opening 212. It will be understood that such a manner of blocking the discharge opening 212 is to open and close part of the discharge opening 212 by means of the wash silo cover 270, also in the case where the wash silo cover 270 is moved between an open position opening said discharge opening 212 and a closed position covering the discharge opening 212. Alternatively, the wash bin cover 270 may also be formed as one piece with the mounting.

Optionally, the discharge opening 212 is sealed by the washing bin cover 270 and the stirring member 19 together, and further, a sealing member is further included, and the washing bin cover 270, the stirring member 19 and the sealing member together seal the discharge opening 212, and the sealing member may be provided on one or more of the washing bin cover 270, the stirring member 19 and the washing bin main body to better seal the discharge opening 212.

Alternatively, the wash bowl cover 270, the agitation member 19 and the mounting seat are formed as one piece.

Optionally, the discharge opening 212 is sealed by the washing bin cover 270, the stirring member 19 and the mounting seat together, and further, a sealing member is further included, the washing bin cover 270, the stirring member 19, the mounting seat and the sealing member together seal the discharge opening 212, and the sealing member may be arranged on one or more of the washing bin cover 270, the stirring member 19, the mounting seat and the washing bin main body. It is understood that the above manner of blocking the discharge opening 212 belongs to the opening and closing of a part of the discharge opening 212 by the wash hopper cover 270, also to the case where the wash hopper cover 270 is moved between an open position opening said discharge opening 212 and a closed position covering the discharge opening 212, and also to the case where the wash hopper cover 270 opens and closes the discharge opening 212.

As shown in fig. 13 and 17B, the wash bin cover 270 may be maintained in a closed position by a magnetic connection in an initial state. Specifically, the wash bin assembly 200 may further comprise a retention member 237 and a retention mating member 238. The holding member 237 can be provided to the cartridge main body 210. In other embodiments not shown, the retaining member 237 may be provided to the mounting support bracket. The mounting support frame is connected with the pot cover 4. The mounting support may be a separate support directly fixed to the lid 4. The retention member 237 and the retention engagement member 238 are both magnetic members. At least one of the retention member 237 and the retention engagement member 238 is a magnet. For example, the retaining member 237 is a magnet, and the retention engagement member 238 is at least one of a magnet, iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel; the holding member 237 is at least one of iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel, and the holding engagement member 238 is a magnet. The wash magazine lid 270 is held in the closed position in the initial state by the magnetic force between the holding member and the holding engagement member 238. Therefore, the washing bin cover 270 can be kept in a closed state due to the magnetic force between the holding member 237 and the holding matching member 238, when the washing cavity 211 is not used, for example, when the cooking appliance 1 does not work or the cooking appliance 1 cooks, the discharge port 212 can be kept closed, the space of the inner pot 3 is isolated from the outside, foreign matters such as dust and insects can be prevented from entering the inner pot 3, so that the inner pot 3 is not polluted and kept clean when the cooking appliance 1 does not work, food in the inner pot 3 is not polluted and the heat preservation effect is good when the cooking appliance 1 cooks, and the cooking efficiency is improved.

The retaining member 237 can be disposed above and below the retention engagement member 238 and have opposite poles facing each other so that the magnetic force therebetween is a magnetic attraction force. The wash bin cover 270 is held in the closed position by a magnetic attraction between the retaining member 237 and the retention engagement member 238. For the illustrated embodiment, as shown in fig. 17B, the retention member 237 is positioned above the retention engagement member 238. The retaining member 237 may be pre-embedded in the washing silo main body 210, for example, formed in the washing silo main body 210 by an injection molding process. Alternatively, in an embodiment not shown, the holding member 237 may also be detachably mounted to the wash cartridge body 210 by fasteners, such as screws. The retaining member 237 may be provided to the cartridge body top wall 216.

In the illustrated embodiment, the retention engagement member 238 is formed as one piece with the translation engagement member 231. In an embodiment not shown, the retention engagement member 238 and the translation engagement member 231 are separate members.

Alternatively, as shown in FIG. 17C, the upper end face of the translation engagement piece 231 may have an angle α with the side end face of the rotation engagement piece 232, wherein α is 30 ° ≦ α ≦ 150 °, such as 30 °, 50 °, 70 °, 80 °, 90 °, 100 °, 110 °, 120 °, 130 °, 150 °, and the like. Preferably, 85 DEG-95 DEG alpha. The magnetic fields generated by the translatory engagement elements 231 and the rotary engagement elements 232 are thus independent of one another and do not interfere as far as possible. When the transmission body 310 is at the driving position, a first magnetic force is provided between the translational driving member 321 and the translational mating member 231, a second magnetic force is provided between the rotational driving member 322 and the rotational mating member 232, and an included angle β is provided between the first magnetic force and the second magnetic force, wherein β is greater than or equal to 30 ° and less than or equal to 150 °, for example, β is 30 °, 50 °, 70 °, 80 °, 90 °, 100 °, 110 °, 120 °, 130 °, 150 °, and the like. Preferably, 85 DEG-beta-95 deg. Fig. 17C schematically shows that the translation mating element 231 is subjected to the first magnetic force Fa from the translation driving element 321, and the rotation mating element 232 is subjected to the second magnetic force Fb from the rotation driving element 322, wherein the angles between Fa and Fb are β.

As shown in fig. 18-20, the transmission assembly 300 may further include a transmission support 330, a mounting bracket 340, and a rotary drive 301. Drive mount 330 can be located within body central bore 313 and attached to drive body 310. Transmission body 310 is rotatable relative to transmission mount 330. A mounting bracket 340 is positioned above the drive body 310 and can be coupled to the drive support 330, for example, by fasteners such as screws. The rotation driving means 301 can be provided to the mounting bracket 340, and an output shaft thereof is connected to the transmission main body 310 to rotate the transmission main body 310. In the embodiment in which the mounting bracket 340 supports the rotation driving means 301 upward, the rotation driving means 301 can be linearly moved together with the transmission main body 310, so that the charged rotation driving means 301 can be disposed at a position other than the pot cover 4.

Specifically, the drive mount 330 may have a downwardly facing mount support surface 332, the mount support surface 332 for abutting the linkage support surface 131. When the feeding bin 110 moves between the first position and the second position, the seat supporting surface 332 abuts against the linkage supporting surface 131, so that the transmission assembly 300 can move smoothly. As the feed bin 110 moves between the second position and the additional position, the holder support surface 332 is separated from the ganged support surface 131.

The support surface 332 may be adapted to the shape of the linkage support surface 131, and may also be configured as a slope inclined in the vertical direction, optionally a conical surface, for example, in the shape of a ring. The drive carrier 330 may be provided with a carrier central bore 331 and a radially outwardly extending carrier boss 333. It will be appreciated that the carrier central aperture 331 is located at the center of the drive carrier 330. The feed cartridge 110 can be positioned within the holder central aperture 331 with the holder support surface 332 disposed about the holder central aperture 331. The top of drive body 310 can be located between carrier boss 333 and mounting bracket 340, which can limit linear movement of drive body 310 relative to drive carrier 330.

The top of the transmission body 310 may be provided with a gear part 314 protruded upward, the gear part 314 surrounding the carrier center hole 331 and having a ring of teeth. The output shaft is provided with a transmission gear 302, and the teeth of the transmission gear 302 mesh with the teeth of the gear portion 314. The illustrated embodiment schematically shows one transmission gear 302 between the output shaft and the gear portion 314, however, the number of the transmission gears 302 is not limited, and may be two or more as needed.

The mounting bracket 340 may be provided with a bracket guide 341, and the bracket guide 341 extends in a vertical direction. Referring back to fig. 10, the storage bin 13 may be correspondingly provided with a vertically extending guide wall 102, at least a portion of the guide wall 102 being located inside the storage bin 13 and connected to the fixed bracket 122 to isolate the transmission structure from the space for storing the food material. Figure 10 schematically shows the guide wall 102 connected to the bottom wall of the storage bin 13, partly above the bottom wall and partly extending downwards from the bottom wall. The holder guide 341 is located in the slide passage 46 defined by the guide wall 102. The mounting bracket 340 may include a bracket base 342 and a bracket riser 343 located above the bracket base 342. The holder base 342 may be provided with a holder guide 341 integrally formed therewith. The holder guide 341 may include, for example, three walls connected in series, and the holder seat 343 is located in a substantially square area surrounded by the three walls. And the stand seat 343 is detachably connected to the stand base 342 by a fastener such as a screw. The rotation driving device 301 is mounted to the holder stand 343 and is also located in the holder guide 341. The support stand 343 has a support cylindrical portion provided at the middle portion thereof, and the output shaft of the rotation drive device 301 is located in the support cylindrical portion. The lower end of the fulcrum section abuts against the transmission gear 302 to restrict the axial movement of the transmission gear 302.

As shown in fig. 5, 8, 21, and 22, the first rotational axis Ax1 may 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. The central axis of the wash chamber 211 is collinear with the first axis of rotation Ax 1. The first rotation axis Ax1 and the second rotation axis Ax2 may each extend in the vertical direction. 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 rotation fitting members 232 are identical in magnetic property and are arranged centrosymmetrically about the first rotation axis Ax 1. The plurality of rotary drivers 322 are magnetically identical and are arranged symmetrically about the second axis of rotation Ax 2. The plurality of rotating matching pieces 232 are uniformly arranged along the circumferential direction of the mounting seat 240; the plurality of rotary drivers 322 are uniformly arranged along the circumferential direction of the transmission body 310. Thereby, the magnetic force applied to the second mounting seat 250 in the circumferential direction can be made 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 drivers 322 engaged therewith also need to be different, but the number of rotary drivers is equal and the rotary drivers are required to be arranged evenly and at intervals. For example, as shown in fig. 22, the number of the rotary driving members is 16, and the number of the rotary driving members may be set to 4 groups, where 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 driving members are NNNN, SSSS, respectively. When the rotary driving device rotates, the outward magnetic poles are the NNNN group rotary driving device and the outward magnetic poles are the rotary mating parts of the SSS group, and the outward magnetic poles are the rotary driving device of the SSS group and the outward magnetic poles are the rotary mating parts of the NNN group. 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. In this embodiment, the second mount 250 rotates the first mount 220 around a limiting component, which includes the inner sidewall 214 and the outer sidewall 215 of the washing cartridge body 210.

The transmission body 310 is configured in a centrosymmetric shape, specifically, a turntable shape as described above. The mount 240 is configured in a centrosymmetric shape. Specifically, the first mount 220 and the second mount 250 are each cylindrical in shape. In the present embodiment, as described above, the mounting seat 240 and the stirrer 19 may be separate members, and specifically, the first mounting seat 220 and the stirrer 19 may be separate members so as to facilitate the mounting of the washer tub cover 270.

As shown in fig. 21, when the transmission body 310 is in the first and second driving positions, i.e., when the rotary drive 322 is in the driving position, the rotary drive 322 corresponds to the position of the rotary engagement element 232 in the radial direction, and the magnetic poles facing each other are opposite. 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 member 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 rotary drivers 322 are arranged in plurality at intervals along the circumference of the transmission body 310. The drive sidewall 312 has a plurality of drive mounting surfaces 315 (fig. 10) arranged circumferentially, the drive mounting surfaces 315 being planar and extending vertically, the rotary drive 322 being mounted to the drive mounting surfaces 315. The rotation fitting 232 is provided in plurality at intervals along the circumferential direction of the transmission body 310. The second mount 250 has a plurality of mount mounting surfaces 253 arranged in the circumferential direction, the mount mounting surfaces 253 being planar and extending vertically, the rotation fitting 232 being mounted to the mount mounting surfaces 253. One of the rotary fitting 232 and the rotary drive 322 may be arranged in a row, the other of the two being vertically spaced apart in two rows. Alternatively, the rotary fitting 232 and the rotary drive 322 may each be provided in a row, and one of the two may be elongated in a vertical arrangement.

Fig. 23 illustrates an embodiment of the wash bin assembly 200 in which the first mount 220 and the second mount 250 are shown in an exploded perspective view, and the translation engagement 231 built into the first mount 220 is exploded from the first mount 220 for ease of understanding.

Considering that the magnetic force decreases with increasing distance, it generally decreases exponentially. When the distance between the translational matching piece 231 and the translational driving piece 321 is large, the magnetic force is seriously attenuated, at this time, the magnetic force cannot overcome the gravity of the washing bin cover 270 and the follow-up load moving along the linear movement of the washing bin cover 270, and the upward movement of the washing bin cover 270 is difficult. On this basis, the present embodiment is provided with an additional drive 239 for providing an upward assisting force to the wash bin cover. The translation driving element 321 and the translation fitting 231 are magnetic members, and an upward first magnetic force F1 exists between the two. The additional driving member 239 is a magnetic member and has an upward auxiliary magnetic force F0 with the translational fitting 231. When the state of the translational drive member 321 is changed to change the first magnetic force, the wash hopper cover moves between the open position of opening the discharge opening and the closed position of closing the discharge opening under the first magnetic force F1, the auxiliary magnetic force F0, and the gravity G1 of the wash hopper cover 270. It is understood that the gravity G1 of the washing bin cover 270 herein refers to the total gravity of the washing bin cover 270 and the follower load moving along the straight line therewith. For the illustrated embodiment, the follower load includes at least first mount 220, translation engagement 231, and stirring element 19.

In this embodiment, the additional drive 239 can provide an upward magnetic force to the wash bin cover 270, advantageously overcoming the weight of the wash bin cover 270 and its follower load, allowing the wash bin cover 270 to easily move upward. Specifically, an upward magnetic force can be generated between the additional driving member 239 and the translational mating member 231, and when the transmission body 310 is moved to a certain position towards the washing bin cover 270 when the washing bin cover 270 is intended to be moved to the closed position, an upward magnetic force can be generated between the translational mating member 231 and the translational driving member 321, and the resultant force of the two magnetic forces urges the washing bin cover 270 to be moved to the closed position. Therefore, the additional driving member 239 is arranged to form the anti-gravity type washing bin assembly 200, the washing bin cover 270 can receive upward magnetic force from the additional driving member 239 to reduce the influence of gravity on the washing bin cover 270 and the load thereon, and the problem that the stroke of the magnetic force for driving the washing bin cover 270 to move up and down is small is effectively solved, and the magnetic force for driving the washing bin cover 270 to move up and down is still effective under the condition that the stroke requirement of the washing bin cover 270 is large, for example, under the condition that the stroke of the washing bin cover 270 is greater than or equal to 20 mm.

The additional drive member 239 is a magnet, which may be located radially outward or radially inward of the translation engaging member 231. Therefore, when the translational mating member 231 moves linearly relative to the additional driving member 239, the magnetic field intensity generated by the additional driving member 239 changes little in the moving direction of the translational mating member 231, so that the auxiliary magnetic force F0 changes little and can exist stably; thus, the additional driving member 239 may provide a relatively stable upward magnetic force to the washer magazine cover 270. An additional drive 239 may be provided to the wash hopper body 210. In the illustrated embodiment, the additional drive 239 is provided to the second mount 250.

The additional driving member 239 may be provided in plural, and the plural additional driving members 239 are uniformly provided in the circumferential direction. Therefore, the washing bin cover is approximately same in all positions in the circumferential direction due to the magnetic force provided by the additional driving piece 239, and can be stressed in a balanced manner when moving up and down, so that friction between the washing bin cover and adjacent parts due to deflection is avoided, and the washing bin cover always keeps moving along a straight line.

For the illustrated embodiment, the rotational engagement element 232 may also be referred to as an additional drive element 239. That is, a magnetic force exists between the additional driving member 239 and the rotary driving member 322, and the stirring member 19 can be driven to rotate.

In particular, in the illustrated embodiment, the translation fittings 231 are shown as one and configured in a ring, i.e., the translation fittings 231 are ring-shaped members, such as circular ring-shaped members. Translation fitting 231 has a first pole 233. The first magnetic pole 233 may be an N pole or an S pole. The first magnetic pole 233 faces in a closing direction of the washer bin cover 270, specifically, upward. It will be appreciated that the translation engagement member 231 has a third magnetic pole opposite the first magnetic pole 233 facing in the closing direction of the magazine lid 270, the third magnetic pole being of opposite polarity to the first magnetic pole 233.

The additional driving member 239 may be provided in plurality. A plurality of additional driving members 239 are arranged along a circumferential direction of the wash bin assembly 200, in particular, arranged on a radially outward outer surface of the second mounting seat 250 along a circumferential direction of the second mounting seat 250. Each additional driver 239 has a second pole 234. The second magnetic pole 234 may be an N pole or an S pole. The second magnetic pole 234 faces in a radially outward direction of the cartridge assembly 200, in particular, in a radially outward direction of the second mount 250. It will be appreciated that the additional driver 239 has a fourth pole opposite the second pole 234 facing in a radially inward direction of the second mount 250, the fourth pole being of opposite polarity to the second pole 234.

Depending on the arrangement, the plurality of additional drives 239 may include N1 first additional drives 235 and N2 second additional drives 236. The second poles 234 of the N1 first additional drivers 235 are all S poles. The second magnetic poles 234 of the N2 second additional drivers 236 are all N-poles. When N1> N2, the first magnetic pole 233 is S pole, and when N2> N1, the first magnetic pole 233 is N pole, where N1 ≧ 0 and N2 ≧ 0. That is, the first magnetic pole 233 of the translation engaging member 231 has the same magnetic pole as the second magnetic pole 234 of the first additional driving member 235 or the second additional driving member 236, which is larger in number.

The first additional driver 235 and the second additional driver 236 may be arranged in a periodic cycle along the circumferential direction. The number of first additional drives 235 is different from the number of second additional drives 236 in each cycle. Therefore, the washing bin cover 270 receives upward magnetic force provided by the additional driving member 239, the positions in the circumferential direction are approximately the same, the washing bin cover 270 can be stressed in a balanced manner when moving up and down, and friction between the washing bin cover 270 and adjacent parts of the washing bin cover due to deflection is avoided, so that the washing bin cover is always kept in linear motion.

Fig. 23 schematically shows that a plurality of additional drive members 239 are arranged in a row in the axial direction of the magazine assembly 200, wherein the additional drive members 239 are configured as elongate, i.e. elongated members, and are arranged vertically. However, if needed and/or desired, the plurality of additional drivers 239 may be arranged in two axially rows, the additional drivers 239 of the two rows having coinciding circumferential positions, in particular coinciding up and down.

The number of the plurality of additional drive members 239 in a single row is N. The second mount 250 of the wash bin assembly 200 may have M mounting sites 224, and the M mounting sites 224 may be arranged in a circumferential annular array. For example, the radially outward outer surface of second mount 250 may include M mounting planes of substantially the same size arranged circumferentially, one mounting location 224 on each mounting plane. Each of the plurality of additional driving members 239 of the single row corresponds to one mounting location 224, i.e. for one row of additional driving members 239 one mounting location 224 is provided with one additional driving member 239 and for two rows of additional driving members 239 one mounting location 224 is provided with two additional driving members 239 arranged one above the other. Where M ≧ N, N = N1+ N2 for one row of additional drive members 239, and N =2 × (N1 + N2) for two rows of additional drive members 239.

When M = N, each mounting location 224 may be provided with an additional drive member 239. The first additional driver 235 may be labeled S as an element; the second additional driver 236 is labeled N as an element. By way of example, in an embodiment having three elements in one cycle, the cyclic pattern of the single row of the plurality of additional drives 239 may be S-N-S and S-S-N, in this example the first pole 233 of the translation counterpart 231 is the S pole; the periodic cycle may also be N-N-S and N-S-N, in this example, the first magnetic pole 233 of translation fit 231 is N-pole. In an embodiment with four elements in one cycle, the periodic cyclic pattern of the single row of the plurality of additional drivers 239 may be S-N-S and S-N-S, in this example the first magnetic pole 233 of the translation counterpart 231 is S-pole; the periodic cycle may also be N-S-N-N and N-N-S-N, in this example the first pole 233 of the translation partner 231 is N-pole. Five or more elements may be provided in one period, and a periodic circulation manner may be provided as necessary.

When M > N, the wash bin assembly 200 has a vacant mounting location 225 where the additional drive member 239 is not located. The first additional driver 235, the second additional driver 236, and the vacant mounting sites 225 may be arranged in a periodic cycle in the circumferential direction. The washing bin cover 270 is subjected to the magnetic force provided by the additional driving piece 239, the positions in the circumferential direction are approximately the same, and the washing bin cover 270 can be stressed in a balanced manner when moving up and down; and the arrangement of the additional driving member 239 is more diversified, the application range is wide, and the design freedom of the product is improved.

The vacant install bit 225 may be marked as 0 as an element. Figure 23 shows that in an embodiment with four elements in one cycle, the cyclic pattern of the single row of the plurality of additional drives 239 may be S-N-S-0, in this example the first pole 233 of the translation counterpart 231 is the S pole.

Fig. 24 shows another embodiment of the wash magazine assembly 200, which differs from the embodiment shown in fig. 23 in that the wash magazine assembly 200 comprises a plurality of translatory fittings 231. The plurality of translation engaging elements 231 may be detachably mounted to the second mounting seat 250 by a fastener such as a screw, the plurality of translation engaging elements 231 is circumferentially arranged on the upper surface of the second mounting seat 250, and the first magnetic poles 233 of the translation engaging elements 231 are identical.

Figure 23 shows that in an embodiment with four elements in one cycle, the cyclic pattern of the single row of the plurality of additional drives 239 may be N-S-N-0, in this example the first pole 233 of the translation counterpart 231 is N-pole. Of course, in embodiments having four elements in a cycle, the cyclic pattern may be N-N-S-0 and S-S-N-0, etc. Five or more elements including 0 may be included in one period, and a periodic cycle pattern may be set as necessary.

The whole washing operation of the cooking appliance 1 of the present embodiment is described below with reference to fig. 2 to 9:

as shown in fig. 2, the cooking appliance 1 is in an initial state. At this time, the feeding bin 110 and the transmission assembly 300 are both in the initial position of the first position, 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 the washing bin cover 270 is in the closed position. In an initial state, the stress relationship of the washing bin cover 270 is that F1+ F2+ F0 is greater than or equal to G1+ G2, wherein F1 is the magnetic force between the translational matching piece 231 and the translational driving piece 321; f2 is a magnetic force between the retaining member 237 and the retaining engagement member 238, and F0 is an upward auxiliary magnetic force existing between the additional driving member 239 and the translational engagement member 231, that is, F0 is an upward magnetic force provided by the additional driving member 239 for the washing bin cover 270, and the magnetic field intensity generated by the additional driving member 239 can be set to be less variable as required, so that the auxiliary magnetic force F0 can be less variable; g1 is the total weight of the washing bin cover 270 and the follow-up load moving linearly therewith, and in this embodiment, the follow-up load at least includes the first mounting seat 220, the translational mating piece 231 and the stirring piece 19; g2 is the weight of the water and the material in the material washing cavity 211. It is understood that G1 is a fixed value and F1, F2, and G2 are variable values. In this state, F1 is small, possibly even close to or equal to 0, and F2+ F0 ≧ G1+ G2 when F1= 0; f2max, i.e., F2max; g2=0, or G2 is the weight of a small amount of residual water after washing on the washing cavity 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. As shown in fig. 3, the cooking appliance 1 is in a ready-to-feed state. At this time, the feeding bin 110 and the transmission assembly 300 are both located at the first driving position in the second position, 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 the washing bin cover 270 is still located at the closed position. In the state shown in fig. 3, the force relationship of the washing bin cover 270 is F1+ F2+ F0> G1+ G2, where F1 and F2 are the largest, i.e. F1max, F2max, G2 are the same as in the initial state. Thereby, the washer magazine cover 270 is subjected to an upward magnetic force and the washer magazine assembly 200 is magnetically coupled in a radial direction. Then the linear driving device 120 can continue to drive the screw 121, and the feeding bin 110 continues to move downwards and extends into the washing cavity 211 without the transmission assembly 300 moving therewith. As shown in fig. 4, the cooking appliance 1 is in a blanking state. At this time, the feeding bin 110 is in the additional position, the transmission assembly 300 is in the first driving position in the second position, the feeding bin 110 is still communicated with both 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 in 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. The amount of material flowing into the wash chamber 211 can be calculated by time, and the cooking appliance controls the time that the feed bin 110 is in the additional position according to the amount of material required by the user, so as to realize quantitative blanking. In this blanking state, water can be supplied to the material washing chamber 211, either simultaneously with blanking or 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 relationship of the washing bin cover 270 is F1+ F2+ F0> G1+ G2, wherein F1 and F2 are F1max and F2max, and G2 is the weight of water and the material.

When the blanking operation is completed, 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. 5. In the state shown in fig. 5, water may be supplied to the wash chamber 211, or water may be supplied to the wash chamber in the state of fig. 4. When water is supplied in the state shown in fig. 5, the weight of G2 increases. After the water supply is completed, the rotation driving device 301 may drive the transmission main body 310 to rotate, and then the magnetic force between the rotation driving component 322 and the rotation matching component 232 may 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 waste pipe 10. When the water level height drops to the highest position that is less than sewage pipes 10, because here drainage channel has been in full flow state, because the water level in washing material chamber 211 is higher than the water level of the delivery port 114 of blow off pipe 107 this moment, according to bernout's principle, the export of blow off pipe 107 can have a speed flood peak this moment, can be with clean the water in the washing feed bin. When the drainage is finished, the stress relation of the washing bin cover 270 is F1+ F2+ F0> G1+ G2, wherein F1 and F2 are F1max and F2max, and G2 is the weight of the material after water absorption and a small amount of residual water. If necessary, clear water can be added after the water is drained for cooking; in this case, G2 is the weight of the water-absorbed material and the clear water.

The action of throwing material and drainage when can repeatedly carry out water supply, washing material realizes washing material many times of single material.

When the discharging action is completed and the blanking is intended, the linear driving device 120 drives the feeding bin 110 to move upward to the middle position in the first position, as shown in fig. 6. In the state shown in fig. 6, the force relationship of the washing bin cover 270 is F1+ F2+ F0< G1+ G2, wherein F1 is reduced, i.e. F1< F1max, F2 is F2max, and G2 is the same as when the drainage is completed. Since F1+ F2+ F0< G1+ G2, the washer bin cover 270 is unbalanced in force, cannot be maintained in the closed position and will move downward, and the discharge opening 212 will be opened. The cooking appliance is quickly switched from the state shown in fig. 6 to the state shown in fig. 7, i.e. the wash bin cover 270 is moved downwards to the open position, wherein the process F1 continues to decrease and F2 decreases. As shown in fig. 7, the wash bin cover 270 has been in the open position and the discharge opening 212 has been opened. At this time, part of the materials and/or water falls into the inner pot 3, and G2 is reduced. In the state shown in fig. 7, the force relationship of the washing bin cover 270 is F1+ F2+ F0< G1+ G2, where F1< F1max and F2 are the minimum, i.e., F2min, and G2 is the weight of the remaining water-absorbing material and a small amount of remaining water. The linear drive 120 then moves the screw 121 downward from the intermediate position to a second drive position in the second position. At this time, as shown in fig. 8, the cooking appliance 1 is in a blanking state. A distance d1 is reserved between the translation driving member 321 and the translation matching piece 231, the stress relationship of the material washing bin cover 270 is F1+ F2+ F0< G1+ G2, wherein F1< F1max, and F2 are F2min, and G2 is the same as that in the state shown in fig. 7, so that the material washing bin cover 270 is always kept at the opening position in the blanking process. Then, the rotation driving device 301 drives the transmission main body 310 to rotate again, so that the stirring piece 19 rotates to start throwing the material, the material falls into the inner pot 3 quickly under the action of centrifugal force. When the material is thrown, G2 is continuously reduced, and after the material is thrown, the force bearing relationship of the washing bin cover 270 is F1+ F2+ F0< G1+ G2, wherein F1< F1max, F2 are F2min, and G2 is the weight of a small amount of residual water. As an example, the difference between F1+ F2+ F0 and G1+ G2 at this time may be 30G.

After the blanking operation is completed, when the reset operation 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 fig. 9, in this process, F1 is increased, at this time, a distance d2 is provided between the translational driving member 321 and the translational mating member 231, d2 is smaller than d1, and the stress relationship of the washing bin cover 270 is F1+ F2+ F0> G1+ G2, where F1 is F1max, F2 is F2max, and G2 is the weight of a small amount of residual water, so that the washing bin cover 270 moves upwards to the closing position under the action of a magnetic force, for example, as shown in fig. 3, the reset operation of the washing bin cover 270 is achieved. The cooking appliance is quickly switched from the state shown in fig. 9 to the state shown in fig. 3, i.e. the lid 270 is moved upwards to the closed position, the process F1 is increased to F1max, the process F2 is increased to F2max, and G2 is the same as the state shown in fig. 9, where F1+ F2+ F0> G1+ G2.

Each action in the process from blanking to blanking can be repeatedly executed, and multiple times of material washing can be realized; i.e. the states shown in fig. 3 to 9 are repeatedly executed.

Then the linear driving device 120 drives the feeding bin 110 to move upwards to the initial position in the first position, as shown in fig. 2, so that the feeding bin 110 and the transmission assembly 300 are reset. This process F1 is reduced to a small value, which may even be close to or equal to 0, F2 is F2max, G2 is the same as in the state of fig. 9, when F1+ F2+ F0> G1+ G2.

It will be appreciated that in other embodiments not shown, the wash bin cover 270 may be in an open position in the initial state. In other words, when the cooking appliance 1 is not in operation, the discharge opening 212 may be in a normally open state, i.e., the washing bin cover 270 is in an open position in the initial state. Specifically, the remaining structure is the same as that of the cooking appliance of the illustrated embodiment except that the holding member 237 and the holding engagement member 238 are eliminated, and only the differences will be described in detail herein for the sake of brevity. In particular, the cartridge assembly 200 does not include the retaining member 237 and the retention engagement member 238, i.e., there is no F2, F2 being the magnetic force between the retaining member 237 and the retention engagement member 238. Therefore, in the initial state, 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+ F0< G1+ G2, in which state F1 is small and may even be close to or equal to 0, G2=0, or G2 is the weight of a small amount of residual water after washing on the washing material cavity 211. When the blanking operation is intended, the magazine cover 270 needs to be moved from the open position to the closed position, that is, the linear driving device 120 can drive the screw rod 121 to move, so that the screw rod 121 can drive the feeding magazine 110 to move downward to the first driving position (as shown in fig. 3) in the second position. At this time, the force relationship of the washing bin cover 270 is F1+ F0> G1+ G2, and the washing bin cover 270 moves to the closed position under the action of magnetic force.

The rest of the blanking operation, the washing operation, the draining operation, the blanking operation, and the water supplying operation are the same as the operation of the cooking appliance of the illustrated embodiment, except that the magnetic force applied to the washing bin cover 270 is F1+ F0, but not F1+ F2+ F0, i.e., the magnetic force of F2 is not present, but the relationship between the magnetic force of the washing bin cover 270 and the G1+ G2 in the blanking stage, the washing stage, the draining stage, and the blanking stage is the same as the relationship between the magnetic force applied to the cooking appliance of the illustrated embodiment in the same stage, and the operation of the linear driving device 120 and the rotary driving device 301 is also the same. Taking the blanking stage as an example, for the embodiment that the discharge opening 212 is normally open, the force-bearing relationship of the washing bin cover 270 is F1+ F0> G1+ G2; for the illustrated embodiment, the force relationship of the wash bin cover 270 is F1+ F2+ F0> G1+ G2. The magnetic force of the blanking stages of the two embodiments is larger than G1+ G2, namely the magnitude relation is consistent. The difference is that after the blanking action is completed, the washing bin cover 270 does not need to be reset, that is, the washing bin cover 270 is kept in the open state, and after the linear driving device 120 drives the feeding bin 110 to move upwards to the initial position in the first position, the washing bin cover 270 is kept in the open state continuously.

In addition, in an embodiment, not shown, a water supply pipe, which may communicate with the wash material chamber 211, may be separately provided to directly supply water to the wash material chamber 211. Thereby, water can be supplied to the washing chamber 211 at any stage of the entire washing operation. A feeding device which can be communicated with the washing cavity 211 can be arranged, the feeding device can not move relative to the storage bin 13, and a feeding piece such as a rotary screw rod and the like is arranged in the feeding device to feed the washing cavity 211.

Furthermore, in other embodiments not shown, both translation fitting 231 and rotation fitting 232 are located inside 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 located inside the material washing cavity 211 may be included. To which both the washer bin cover 270 and the stirrer 19 can be connected. 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.

It should be noted that, the stress relationship mentioned herein can be understood as the stress relationship of the washing bin cover 270 and the assembly constituted by the following load moving along the straight line, and for the sake of brevity, it is simply referred to as the stress relationship of the washing bin cover 270; similarly, the descriptions of magnetic force, magnetic force, gravity, etc. used herein to describe the washing bin cover 270 may be understood as various descriptions of the force of the assembly of the washing bin cover 270 and the follow-up load moving along the straight line, and for the sake of brevity, the washing bin cover 270 is simply replaced, and as an example, the magnetic force of the washing bin cover 270 is understood as the magnetic force of the assembly of the washing bin cover 270 and the follow-up load moving along the straight line.
