The pot cover and the pot body are not provided with charged components, so that the water resistance is not needed to be considered integrally, and the pot cover and the pot body can be placed under a faucet for flushing.

The entire operation of the cooking appliance 1 according to the preferred embodiment will be described with reference to fig. 2 to 7 as follows:

as shown in fig. 2, the cooking appliance 1 is in an initial state. At this time, the feeding bin 16 is in the first position, and the feeding bin 16 is not communicated with the outlet 14 of the storage bin 13 and the feed inlet 7 of the washing bin assembly 5.

When the blanking operation is intended, the first driving device 21 can drive the first transmission device to act, so that the first transmission device can drive the feed bin 16 to move downwards to the second position. As shown in fig. 3, the cooking appliance 1 is in a blanking state. At this time, the feeding bin 16 is at the second position, and the feeding bin 16 is communicated with the outlet 14 of the storage bin 13 and the feeding port 7. When in the blanking state, the feed inlet 88 can be communicated with the outlet 14 of the storage bin 13, and the discharge outlet 82 can be communicated with the feed inlet 7 of the washing bin assembly 5, so that the material in the storage bin 13 enters the feed bin 16 through the feed inlet 88 and then enters the washing bin assembly 5 through the discharge outlet 82. The amount of rice flowing into the wash chamber can be calculated by time.

After the blanking operation is completed or at the same time as the blanking operation, the control unit may control the water pump of the water inlet assembly to be turned on, so that water in the clean water tank is introduced into the washing bin main body via the water inlet pipeline 99 to be ready for the washing operation.

When the discharging operation and the draining operation are completed, the first driving device 21 drives the first transmission device to act, and the first transmission device drives the feeding bin 16 to move upwards to the third position, as shown in fig. 4. Wherein the third position is located between the first position and the second position. When in the third position, the feed bin 16 is not in communication with the outlet 14 of the storage bin 13 and the feed inlet 7 of the washing bin assembly 5. By setting the third position, the scheme can divide the stroke of the up-and-down movement of the transmission shaft 26 into a section to the feed bin 16, so that the movement stroke of the transmission shaft 26 can be reduced, and the transmission shaft 26 is prevented from being overlong.

When a washing operation is intended, as shown in fig. 5, 13 and 14, the third driving means 28 may drive the first gear 29 to rotate, the first gear 29 to rotate the second gear 30, and the second gear 30 to drive the drive screw 31 to move downwards, whereby the drive shaft 26 also moves downwards with the drive screw 31 into engagement with the connecting shaft 27 of the washing silo assembly 5, as the drive screw 31 is sleeved outside the drive shaft 26. The second drive means 24 can be opened at this time so that the second drive means 24 drives the drive shaft 26 to rotate, whereby the drive shaft 26 can drive the connecting shaft 27 to rotate. When the connection shaft 27 is rotated, the rotation shaft 33 engaged with the connection shaft 27 and the stirring member 19 can be rotated, so that a washing operation can be performed. The material washing cavity is provided with materials and water, and the materials and the water are stirred together under the drive of the stirring piece 19. It will be appreciated that the washing bin cover 17 is located above the drain 9 when a washing operation is performed.

When the washing operation is completed and the water is to be drained, the third driving device 28 can be opened to drive the transmission screw 31 to move downwards, and the transmission screw 31 pushes the rotating shaft 33 downwards, so that the stirring piece 19 can be moved downwards. When the stirring member 19 moves down to the position where the washing chamber cover 17 moves below the drain opening 9, as shown in fig. 6, the third driving means 28 is controlled to stop, and at this time, the sewage in the washing chamber can flow to the drain pipe 10 and the sewage tank 48 through the drain opening 9.

When the draining is completed and the discharging operation is intended, the third driving device 28 can be controlled to be opened to drive the transmission screw 31 to move downwards, the transmission screw 31 pushes the rotating shaft 33 downwards, and the stirring piece 19 can be moved downwards to leave the material washing cavity, as shown in fig. 7. When the stirring piece 19 moves downwards to leave the material washing cavity, the third driving device 28 is controlled to stop acting, and the second driving device 24 is controlled to be opened, so that the stirring piece 19 can be driven to rotate, and washed rice is thrown into the inner pot 3.

After or while throwing the rice into the inner pot, the control unit may control the water pump of the water inlet assembly to be turned on, so that water in the clean water tank is introduced into the wash chamber via the water inlet line 99 and flows into the inner pot via the wash chamber to be ready for cooking.

After the blanking operation is completed, the third driving device 28 may drive the drive screw 31 to move upwards, and after the drive screw 31 moves upwards into the feeding bin 16, the first driving device 21 may drive the feeding bin 16 to return to the first position. At this time, the rotation shaft 33 and the stirring member 19 connected thereto may be returned upward to the original position by the elastic member 40.

According to the cooking utensil 1 of the embodiment, the inner pot 3, the pot cover 4, the washing bin assembly 5, the clean water tank 81 and the sewage tank 48 can be easily detached for washing, so that the cleaning process of the whole cooking utensil 1 is simplified.

Second embodiment

The cooking appliance according to the second preferred embodiment of the present invention will be described in detail below with reference to the drawings, and the cooking appliance according to the second preferred embodiment is substantially identical in structure to the cooking appliance according to the first preferred embodiment except for the transmission assembly, and only the differences will be described in detail herein for the sake of brevity.

As shown in fig. 43, in the present embodiment, the cooking appliance 1 further includes a transmission assembly 300, and the transmission assembly 300 is movable along a straight line. Specifically, the drive assembly 300 is engageable with the feeder hopper 110 to move the drive assembly 300 with the feeder hopper 110 between a first position (as shown in fig. 44) and a second position (as shown in fig. 45). The transmission assembly 300 can drive at least a portion of the washing bin assembly 200 to rotate, for example, at least the stirring member 19 to complete the process of throwing the material during washing and/or blanking; and can drive the stirring member 19 to move between the open position and the closed position together with the washing bin cover 270 to complete the discharging and draining processes.

The drive assembly 300 is disposed in the storage or feed mechanism 100. In particular, the transmission assembly 300 is not provided on the lid 4. According to the scheme, the charged transmission assembly 300 is arranged at the position outside the pot cover 4, so that components on the pot cover 4 can be reduced, the pot cover is simpler in structure, meanwhile, a user can conveniently clean the pot cover 4 and the washing bin assembly 200, and the scheme can enable the water prevention of the transmission assembly 300 to be omitted in the manufacturing stage of the pot cover 4, so that the manufacturing process is simplified.

The storage mechanism, the feeding mechanism 100, the transmission assembly 300 and the washing silo assembly 200 described above constitute a part of the washing system of the present embodiment.

The transmission structure between the feeding mechanism 100, the transmission assembly 300 and the washing tub assembly 200 will be described in detail with reference to the accompanying drawings.

The feed mechanism 100 may be coupled to the drive assembly 300 by a contact drive. The transmission assembly 300 may be coupled with the washing tub assembly 200 by a magnetic force generated by the magnetic member, and a non-contact transmission may be formed between the transmission assembly 300 and the washing tub assembly 200. In this embodiment, the washing compartment cover 270 may be located at a closed position or an open position in an initial state. In other words, the discharge port 212 may be in a normally closed state or a normally open state when the cooking appliance 1 is not operated.

In the illustrated embodiment, one embodiment of a drive arrangement between the feed mechanism 100, the drive assembly 300 and the wash bin assembly 200 is shown. And the discharge opening 212 is schematically shown in a normally closed state.

As described above, the feeder hopper 110 is movable in a straight line with the drive assembly 300 between the first and second positions. As shown in fig. 46, the feed bin 110 also has additional locations. The feed bin 110 is closer to the wash chamber 211 in the additional position. The feed bin 110 has a feed channel for transporting solid material, which feed channel is not in communication with both the storage bin 13 and the wash chamber 211 in the first position and in the second position. When the feed bin 110 is moved to the additional position, the drive assembly 300 does not move therewith. In this way, the feed bin 110 can in the additional position extend out of the drive assembly 300 into the washing space 211, in which case the feed channel of the feed bin 110 can communicate with both the storage bin 13 and the washing space 211. In this embodiment, the feed bin 110 has a two-stage motion relative to the drive assembly 300, wherein the feed bin 110 moves with the drive assembly 300 in one stage of motion, i.e., from the first position to the second position, and the second position returns to the first position; in another movement, i.e. from the second position to the additional position, and from the additional position to the second position, the feed bin 110 is moved apart from the drive assembly 300. The feeding bin 110 can be moved from the second position to the additional position and from the additional position to the second position, so that the feeding bin 110 can enter or leave the washing cavity 211, facilitating the blanking and ending of the blanking.

The wash bin assembly 200 is located below the drive assembly 300. When the feed bin 110 is in the additional position, the drive assembly 300 may abut the top surface of the wash bin body 210 such that the drive assembly 300 can stop moving when the feed bin 110 is moved from the second position to the additional position. In other embodiments, not shown, a separate fixed support is included, by which the transmission assembly 300 is abutted when the feeding bin 110 is in the additional position, which may be a separate support directly fixed to the lid 4.

As shown in fig. 52-54, the feed mechanism 100 may also include a linkage 130. The linkage 130 is disposed at the bottom of the feed bin 110, for example, a bottom surface of the feed bin 110 is provided with a rotary connection structure 117, the linkage 130 is provided with a structure cooperating with the rotary connection structure 117, and the linkage 130 is rotated to be connected to the rotary connection structure 117. And the linkage 130 is fixed to the rotary connection structure 117 with screws. 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 the lower side of the driving body 310 and is provided with an upwardly facing link support surface 131 for supporting the driving assembly 300 upwardly. 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 drive assembly 300 can move downwardly with the feeder hopper 110 as it moves downwardly by its own weight. The linkage support surface 131 may be configured as a sloped surface that slopes in a vertical direction, with the illustrated embodiment showing the linkage support surface 131 as an annular tapered surface, specifically sloping outwardly from top to bottom in a radial direction of the linkage 130. Thus, the feeding bin assembly 110 and the transmission assembly 300 can play a guiding role when moving from the separated state to the combined state, and can be matched better.

The feeding mechanism 100 further includes a linear drive 120. The linear driving device 120 can be connected to the feeding bin 110, for driving the feeding bin 110 to move along a straight line. Specifically, the feed bin 110 is provided with a vertically extending screw hole 115, and the feed mechanism 100 further includes a screw 121. The screw 121 can be connected to the output shaft of the linear drive 120 and located within the screw bore 115. When the output shaft rotates, the screw 121 can move relative to the feed bin 110 within the screw hole 115, thereby moving the feed bin 110 up and down.

The feeding mechanism 100 further includes a fixing bracket 122, a fixing base 123, and a fixing platen 124. The fixing bracket 122 is located in the storage bin 13 and is connectable to the storage bin 13, and for example, as one example, an inner bottom surface of the storage bin 13 may be provided with a stud (not shown) extending upward, the fixing bracket 122 may be provided with screw stages 126 having through holes at intervals, through which screws can be locked to the stud, whereby the fixing bracket 122 may be mounted to the storage bin 13. The fixed bracket 122 can be provided with a receiving cavity with an opening facing downward, and the linear driving device 120 is connected to the fixed bracket 122 and is located in the receiving cavity. Specifically, the linear driving device 120 is located in a concave 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 actuator 120 to limit the rotation and vertical movement of the linear actuator 120. The fixed platen 124 is located on the opposite side of the linear driving device 120 from the fixed mount 123, i.e., the lower side. The fixed platen 124 may be connected to the fixing base 123, for example, the fixed platen 124 and the fixing base 123 are provided with screw holes, the fixing bracket 122 is provided with screw columns 127 extending downward, and screws are fastened to the screw columns 127 through the screw holes of the fixed platen 124 and the fixing base 123. The end of the screw 121 is sandwiched between the fixed platen 124 and the fixed mount 123.

An outlet of the storage bin 13 may be formed between the bottom of the fixing bracket 122 and the inner bottom surface of the storage bin 13. The outlet is located on one side of the fixed bracket 122. The fixing bracket 122 is provided with an outlet seal 125 at a side corresponding to the outlet. The outlet seal 125 can abut the sidewall of the feed bin 110 to prevent material from entering the feed mechanism 100. The fixed brackets 122 are also provided with guide posts 128 extending vertically at intervals. The top of the feed bin 110 is provided with guide protrusions 116 at intervals, and the guide protrusions 116 protrude from the side walls of the feed bin 110. The guide tabs 116 are positioned between spaced apart guide posts 128 and are movable along the guide posts 128 to prevent displacement of the feed bin 110 during movement.

The wash bin assembly 200 also includes a wash bin fitting 230 and a mount 240. The sink mating member 230 may be coupled to the mounting block 240. Some or all of the mounting seats 240 may be movably provided to the washing tub main body 210 along a straight line. In the illustrated embodiment, a portion of the mount 240 is movable along a straight line. The stirring element 19 is located in the washing chamber 211 and is connected to the mounting seat 240, the stirring element 19 being rotatable with the mounting seat 240 about the first rotation axis Ax1 with respect to the washing silo body 210. The washing bin cover 270 may be provided to the mount 240 and movable along a straight line along with the mount 240. The mount 240 is rotatable relative to the sink body 210 about a first rotational axis Ax 1. The transmission assembly 300 includes a transmission body 310 and a wash bin drive 320. The drive body 310 is rotatable relative to the washing silo body 210 about a second rotation axis Ax 2. The drive body 310 is engageable with the feed bin 110 and rotatable relative to the feed bin 110. The washing tub driver 320 is provided to the transmission body 310, and may be mounted to the transmission body 310 by screw connection or the like, for example.

The sump coupler 230 and the sump driver 320 may have a magnetic force therebetween. 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 sump coupler 230 and the sump driver 320 is changed, the mount 240 moves in a straight line to open and close the sump cover 270.

The transmission body 310 has a non-driving position (e.g., different blanking states shown in fig. 48 and 49) that causes the cartridge engagement member 230 to be out of engagement with the cartridge driving member 320, and a driving position that causes the cartridge engagement member 230 to be in engagement with the cartridge driving member 320. Wherein the drive positions include a first drive position (e.g., each of the states shown in fig. 45 to 47) and a second drive position (e.g., the blanking state shown in fig. 50). The first drive position corresponds to the closed position and the second drive position corresponds to the open position, the non-drive position may be the open position (different blanking conditions as shown in fig. 48 and 49) or the closed position (such as the initial position of fig. 44), although in other embodiments the initial position may be set to the open position.

Wherein the first position may be a non-driven position including an initial position and an intermediate position (different blanking states as shown in fig. 48 and 49); 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 sink driving member 320 is out of engagement with the sink mating member 230. When the transmission body 310 is located at the second position, the sump driver 320 is coupled with the sump mating member 230. The intermediate position is located between the initial position and the second drive position. For ease of understanding, fig. 48 and 51 show a transition state during the operation, in which the mount 240 provided with the washing bin cover 270 is unbalanced in force.

A contactless transmission is formed between the sink assembly 200 and the transmission assembly 300. When the washing is performed in the washing chamber 211, the washing water exists in a space isolated from the transmission assembly 300, and does not contact the transmission assembly 300. Thus, the washing water can be prevented from fouling the transmission assembly 300. Compared with a mechanical transmission mode, the non-contact transmission mode does not need to clean the transmission structure, and therefore the experience of a user can be improved.

In this embodiment, the feeding bin 110 and the transmission assembly 300 can generate a synchronous movement stroke, and the transmission assembly 300 and the washing bin cover 270 can generate a matched movement, so that only one driving device for driving the feeding bin 110 to move can be arranged, 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 material discharging can be realized.

The wash bin mating member 230 may include a translation mating member 231. The translational fitting 231 is disposed on the mount 240. The wash bin drive 320 may include a translational drive 321. The translational drive is provided to the transmission body 310. The translational driving member 321 and the translational matching member 231 are magnetic members, and magnetic force can exist between the translational driving member and the translational matching member. When the state of the translation driving member 321 is changed to change the magnetic force between the translation fitting member 231 and the translation driving member 321, the washing cartridge cover 270 moves between an open position where the discharge port 212 is opened and a closed position where the discharge port 212 is closed. The drive assembly 300 and the wash bin cover 270 are capable of cooperating movement by magnetic force. When the driving body 310 is moved, the washing tub cover 270 may be opened and/or closed by a magnetic force, thereby enabling the opening and closing of the discharge outlet 212.

In one embodiment, the wash bin cover 270 moves from the open position to the closed position when the state of the translational drive 321 is changed. Thereby, the closing of the washing tub 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 the state of the translational drive 321 is changed. Thereby, the opening of the washing tub cover 270 can be achieved by means of the magnetic force between the translation fitting 231 and the translation driving member 321. In the illustrated embodiment, the cartridge cover 270 moves from the open position to the closed position and vice versa when the state of the translational drive 321 is changed. Thereby, the opening and closing of the washing tub cover 270 can be simultaneously achieved by means of the magnetic force between the translation coupler 231 and the translation driver 321.

The wash bin mating piece 230 may include a rotating mating piece 232. The wash bin drive 320 may include a rotary drive 322. The rotary fitting 232 is provided on the mount 240. The rotary driving member 322 is disposed on the transmission body 310, and the rotary driving member 322 and the rotary matching member 232 are magnets. When the transmission body 310 rotates, the stirring member 19 rotates by the magnetic force between the rotation driving member 322 and the rotation mating member 232. Thus, when the driving body 310 is rotated with the washing tub cover 270 opened and closed, the washing and discharging actions can be achieved.

The magnetic component may include at least one of a magnet, an electromagnet, iron, nickel, cobalt, a ferritic steel, a martensitic steel, an austenitic-ferritic dual phase steel. Alternatively, the magnet may be a permanent magnet. Alternatively, at least one of the translational fitting 231 and the translational driving member 321 may be a magnet. For example, the translation fitting 231 is a magnet; the translational drive 321 is one of a magnet, an electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, austenitic-ferritic dual phase steel. One example is that the translational coupling 231 and the translational driving member 321 are both magnets, whereby a large magnetic force can exist between the translational coupling 231 and the translational driving member 321 and the state is stable. As another example, the translational fitting 231 is iron, nickel, cobalt, ferritic steel, martensitic steel, austenitic-ferritic dual phase steel, and the translational driver 321 is a magnet. Since the magnetism of iron, nickel, cobalt, ferrite steel, martensitic steel, austenitic-ferritic dual-phase steel is not affected by high temperature, it is possible to avoid the high temperature affecting the magnetism of the translational fitting 231 during cooking, so that the performance thereof remains unchanged. Optionally, at least one of the translational fitting 231 and the translational drive 321 is an electromagnet.

When both the washing bin cover 270 and the stirring member 19 are provided to the same mount 240, the translational fitting 231 and the translational driving member 321 are not selected as electromagnets, considering that the rotation of the mount 240 causes the wire to be wound. When the washing bin cover 270 and the stirring member 19 are provided on different mounting seats 240, the switch of the washing bin cover 270 and the rotation of the stirring member 19 are independent, and the translational matching member 231 and the translational driving member 321 may be selected as electromagnets.

For embodiments that do not include an electromagnet, the drive assembly 300 is linearly movable relative to the laundering bin body 210. The wash bin cover 270 moves between an open position that opens the discharge port 212 and a closed position that covers the discharge port 212 as the transmission assembly 300 moves to change the magnetic force between the translational coupler 231 and the translational driver 321. For the illustrated embodiment, the movement direction of the tub cover 270 is controlled to be moved to the open position and the closed position according to the resultant force direction change of the magnetic force and the gravity by controlling the position of the up-and-down movement of the driving assembly 300.

For the embodiment of the electromagnet, the washing bin cover 270 can move in a straight line to open and close the discharge port 212 when the energization state of the electromagnet is changed.

The rotary drive member 322 may be located radially outward of the rotary engagement member 232 in the drive position, depending on design requirements. Alternatively, the rotary drive member 322 may be located radially inward of the rotary engagement member 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 positioned below the transmission assembly 300, and the feeding bin 110, the washing bin cover 270, and the transmission assembly 300 are all movable up and down. The translational drive 321 corresponds to the up-down position of the translational mating member 231 and is opposite or identical in magnetic polarity toward 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 force, and the washing bin cover 270 is moved by the magnetic attraction force; when the magnetic poles are the same, the magnetic force between the translational driving member 321 and the translational matching member 231 is a magnetic repulsive force, and the washing bin cover 270 is moved by the magnetic repulsive force. For the illustrated embodiment, the magnetic poles of the translational drive 321 and the translational mating 231 are opposite, and the magnetic force therebetween is magnetic attraction.

As shown in fig. 52, the transmission body 310 is constructed in a turntable shape and includes a transmission top wall 311 and a transmission side wall 312 connected to the transmission top wall 311. The transmission side wall 312 extends vertically, the translational driving member 321 is disposed on the transmission top wall 311, and the rotational driving member 322 is disposed on the transmission side wall 312. The translational driving member 321 is disposed on the transmission main body 310 by at least one of clamping, fastening connection, and in-film injection molding. The translational drive 321 in the illustrated embodiment is removably mounted to the drive 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 member 321 and the translational matching member 231 may be linked, and the rotational driving member 322 and the rotational matching member 232 may be linked. When the transmission body 310 is located at the second driving position, the translational driving member 321 is out of linkage with the translational matching member 231, and the rotational driving member 322 is in linkage with the rotational matching member 232. For the illustrated embodiment, referring to fig. 50, 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 less than the gravitational force of the wash bin cover 270 and the first mount 220 and the stirring member 19 connected thereto. Whereby the washing compartment cover 270 can be maintained in the open position.

In the present embodiment, the wash bin coupler 230 can be located outside the wash chamber 211, i.e., the rotary coupler 232 and the movable coupler 231 are located outside the wash chamber 211. When the transmission body 310 is located at the first driving position and the second driving position, the rotation driving piece 322 is located radially outside the rotation mating piece 232.

The structure of the washing tub assembly 200 of the second embodiment is described below with reference to fig. 55 to 59.

As shown in fig. 55 and 56, the mount 240 includes a first mount 220 and a second mount 250 connected to the 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 231 may be provided to the first mounting seat 220. The rotary fitting 232 may be provided to the second mount 250. The first mount 220 may rotate with the 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 stirring member 19 and the washing bin cover 270 are provided to the mount base 221. The mounting seat cylinder 222 is located radially outside the wash chamber 211 and is provided with seat openings 224 at its bottom in a circumferentially spaced manner so that during blanking material falls through the seat openings 224 into the inner pan 3. The translational fitting 231 is disposed on top of the mount barrel 222, so that there may be a small distance between the translational fitting 231 and the translational driving member 321, and a magnetic force large enough to move the cartridge cover 270 up and down may be generated.

The translational fitting 231 is disposed on the mounting base 240 by at least one of a snap fit, a fastener connection, and in-film injection molding. As shown in fig. 55, the translational fitting 231 may be pre-embedded into the mount barrel 222, for example, by an in-film injection molding process into the mount barrel 222.

The wash bin assembly also includes a support member. The support member is provided to the washing tub main body 210. The support member is provided with an upwardly facing seat stop surface 252 for supporting the mounting seat 240 upwardly. In this embodiment, the support member includes a second mount 250 and a cartridge body base 217. The second mount 250 is provided with an upwardly facing mount stop surface 252 for supporting the first mount 220 upwardly. The cartridge body base 217 supports the first mount 220 upward. Fig. 58 shows that the mount cylinder 222 is provided with a mount guide groove 223, and the second mount 250 is provided with a mount guide 251. The top surface of the seat guide 251 is a seat limiting surface 252. In an embodiment not shown, the second mount 250 is provided with a mount guide groove 223 and the mount cylinder 222 is provided with a mount guide 251. The bottom surface of the seat guide groove 223 is a seat limiting surface 252.

Alternatively, the mount barrel 222 may include a barrel upper portion and a barrel lower portion. The upper part of the barrel protrudes radially outwards from the lower part of the barrel, i.e. the thickness of the upper part of the barrel is greater than the thickness of the lower part of the barrel. The seat guide groove 223 may be provided at an upper portion of the cylinder, and the seat opening 224 may be provided at a lower portion of the cylinder.

As shown in fig. 55, 59 and 59A, the laundering bin assembly 200 further includes a spout seal 261 in order to avoid water leakage when the laundering action is performed. The port seal 261 can be provided to an outer circumferential portion of the washing tub cover 270 so as to move up and down together with the washing tub cover 270. When the laundering bin cover 270 is in the closed position, the spout seal 261 abuts the laundering bin body 210 at the discharge spout 212. Thereby, the washing compartment cover 270 is pressurized and does not rotate with respect to the first mount 220 and the stirring member 19. When the washing tub cover 270 is located at the closed position, the port seal 261 can seal a gap between the washing tub cover 270 and the washing tub body 210, preventing washing water from leaking out of the gap during washing. When the silo cover 270 is in the closed position and the stirring member 19 is rotated, the silo cover 270 remains stationary with respect to the silo body 210, i.e. the relative position with the silo body 210 remains unchanged, and does not rotate with the stirring member 19. The sealing effect of the material port sealing member 261 can be ensured to be better, and the material washing bin cover 270 can be tightly covered, so that the water leakage condition is avoided.

The washing bin cover 270 is disposed on a side of the mount base 221 facing the washing 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 washing tub cover 270 may be provided with a cover recess 273 recessed radially inward. The cover recess 273 is annular. A portion of the spout seal 261 can be located within the lid recess 273.

The lid support surface 271 faces the side of the discharge opening 212, in particular, faces upward. The throat seal 261 can abut the cap support surface 271 to provide upward support force for the throat seal 261. When the laundering bin cover 270 is in the closed position, the spout seal 261 is sandwiched between the bottom of the laundering bin body 210 and the cover support surface 271, and the laundering bin cover 270 is held stationary relative to the laundering bin body 210 by being pressed downward at the cover support surface 271. In this embodiment, the bottom surface of the side wall portion 6 may abut against the orifice seal 261, specifically, the bottom surface of the inner side wall 214 may abut against the orifice seal 261. The port seal 261 is subjected to a downward compressive force. In other embodiments, not shown, the inner surface of the sidewall portion 6 may abut the port seal 261 and friction between the port seal 261 and the sidewall portion 6 may limit rotation of the wash bin cover 270.

As shown in fig. 59A, the bottom of the cartridge body 210 is provided with a body arcuate surface 218, the body arcuate surface 218 being abuttable against the spout seal 261. The contact area between the bottom of the washing bin main body 210 and the material opening sealing piece 261 can be increased, so that the contact between the two parts is more stable, and the sealing effect is better.

The port seal 261 is an annular member and is fitted around the outer periphery of the flushing bin cover 270. The outer circumferential portion of the washing tub cover 270 may be provided with a cover boss 272 protruding radially outward. The port seal 261 is disposed on the cap boss 272. The upper surface of the cover boss 272 is a cover support surface 271, which can support the washing bin cover 270.

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

The stirring member 19 can be located on the opposite side of the cartridge cover 270 from the mount base 221, specifically the upper side. That is, the washer bin cover 270 is located between the stirring member 19 and the mount base 221. The stirring member 19 is connected to the cover mounting portion 263. One of the stirring member 19 and the cover mounting portion 263 may be provided with a connection protrusion, and the other of the two may be provided with a connection groove in which the connection protrusion is located. Fasteners such as screws may be connected through the mount base 221 to the connection boss to connect the stirring element 19 to the mount base 221. The stirring bar 19 is schematically shown provided with a connection protrusion and the cover mounting portion 263 is provided with a connection recess.

As in the illustrated embodiment, the wash bin cover 270, mount base 221, agitator 19, and port seal 261 are combined together such that when the wash bin cover 270 is in the closed position, the wash bin cover 270, mount base 221, agitator 19, and port seal 261 together block the discharge port 212. When the stirring member 19 and the mount base 211 are rotated together, neither the laundering bin cover 270 nor the mouth seal 261 is rotated, i.e. the relative position to the laundering bin body 210 remains unchanged. The sealing effect of the material port sealing member 261 can be ensured to be better, and the material washing bin cover 270 can be tightly covered, so that the water leakage condition is avoided.

Alternatively, the discharge opening 212 may be blocked by other means, such as the wash bin cover 270 alone blocking the discharge opening 212, or the wash bin cover 270 may block the discharge opening 212 with one or more of the seal, stirrer 19, mount. One or more of the seal, agitator 19, and mounting blocks may move in unison with the cartridge cover 270, i.e., together to open and close the discharge port 212 together. One or more of the seal, agitator 19, and mounting blocks may also be moved apart from the wash bin cover 270 to open and close the discharge port 212.

Alternatively, the discharge opening 212 may be blocked only by the washing bin cover 270, and the discharge opening 212 may be covered only by the washing bin cover 270. Further, a sealing member may be further disposed between the washing bin cover 270 and the washing bin body, and the discharging opening 212 may be plugged together by the washing bin cover 270 and the sealing member, and the sealing member may be disposed on the washing bin cover 270 or the washing bin body.

Optionally, the material outlet 212 is plugged by the material washing bin cover 270 and part of the mounting seat together, and further, a sealing element is further included, and the material washing bin cover 270, part of the mounting seat and the sealing element together plug the material outlet 212. Seals may be provided on one or more of the wash bin cover 270, part of the mounting seat, the wash bin body to better seal the discharge port 212. It will be appreciated that such a closing of the discharge opening 212 is by the opening and closing of a part of the discharge opening 212 by the flushing bin cover 270, also in the case of a flushing bin cover 270 being moved between an open position for opening said discharge opening 212 and a closed position for closing the discharge opening 212. Alternatively, the wash bin cover 270 may also be formed as a single piece with the mount.

Optionally, the material outlet 212 is plugged by the material washing bin cover 270 and the stirring piece 19 together, and further, a sealing piece is further included, and the material washing bin cover 270, the stirring piece 19 and the sealing piece plug the material outlet 212 together, and the sealing piece can be arranged on one or more of the material washing bin cover 270, the stirring piece 19 and the material washing bin main body so as to better seal the material outlet 212.

Optionally, the wash bin cover 270, the stirring member 19 and the mounting base are formed as one piece.

Optionally, the material outlet 212 is plugged by the material washing bin cover 270, the stirring piece 19 and the mounting seat together, further, a sealing piece is further included, the material washing bin cover 270, the stirring piece 19, the mounting seat and the sealing piece together plug the material outlet 212, and the sealing piece can be arranged on one or more of the material washing bin cover 270, the stirring piece 19, the mounting seat and the material washing bin main body. It will be appreciated that the above manner of blocking the discharge opening 212 pertains to the opening and closing of a portion of the discharge opening 212 by the washing compartment cover 270, as well as to the case where the washing compartment cover 270 is moved between an open position for opening said discharge opening 212 and a closed position for covering the discharge opening 212, as well as to the case where the washing compartment cover 270 is opened and closed the discharge opening 212.

As shown in fig. 55 and 59B, the washing compartment 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 include a retaining member 237 and a retaining mating member 238. The holding member 237 can be provided to the washing tub main body 210. In other embodiments not shown, the retaining member 237 may be provided to the mounting 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 holding member 237 and the holding engagement member 238 are both magnetic members. At least one of the holding member 237 and the holding engagement member 238 is a magnet. For example, the holding member 237 is a magnet, and the holding mating member 238 is at least one of a magnet, iron, nickel, cobalt, ferritic steel, martensitic steel, austenitic-ferritic dual phase steel; the holding member 237 is at least one of iron, nickel, cobalt, ferritic steel, martensitic steel, austenitic-ferritic dual phase steel, and the holding mating member 238 is a magnet. The wash bin cover 270 is maintained in a closed position in an initial state by a magnetic force between the holding member and the holding engagement member 238. Thus, the tub cover 270 may be kept in a closed state by the magnetic force between the holding member 237 and the holding mating member 238, and when the tub 211 is not used, for example, the cooking appliance 1 is not operated or the cooking appliance 1 is cooking, the drain 212 may be kept closed, the space of the inner pot 3 may be isolated from the outside, foreign matters such as dust, insects, etc. may be prevented from entering the inner pot 3, thereby keeping the inner pot 3 clean when the cooking appliance 1 is not operated, food in the inner pot 3 is not polluted and the heat preservation effect is good when the cooking appliance 1 is cooking, and the cooking efficiency is advantageously improved.

The holding member 237 can be disposed up and down with the holding engagement members 238 and have opposite magnetic poles facing each other so that the magnetic force therebetween is a magnetic attraction force. The washer housing cover 270 is held in the closed position by the magnetic attraction between the holding member 237 and the holding engagement member 238. For the illustrated embodiment, as shown in fig. 59B, the retaining member 237 is located above the retaining engagement member 238. The retaining members 237 may be pre-embedded into the washing silo body 210, such as by an in-film injection molding process into the washing silo body 210. Alternatively, in an embodiment not shown, the retaining member 237 may also be removably mounted to the washing silo body 210 by fasteners such as screws. The retaining member 237 may be provided on 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. 59C, the upper end surface of the translational fitting 231 may have an angle α with the side end surface of the rotational fitting 232, where 30 ° +.α+.150 °, such as 30 °, 50 °, 70 °, 80 °, 90 °, 100 °, 110 °, 120 °, 130 °, 150 °, etc. Preferably, 85 DEG.ltoreq.alpha.ltoreq.95 deg. Whereby the magnetic fields generated by the translatory coupling 231 and the rotary coupling 232 are independent and do not interfere with each other as much as possible. When the transmission body 310 is in the driving position, a first magnetic force is provided between the translational driving element 321 and the translational matching element 231, a second magnetic force is provided between the rotational driving element 322 and the rotational matching element 232, and an included angle beta is provided between the first magnetic force and the second magnetic force, wherein beta is more than or equal to 30 degrees and less than or equal to 150 degrees, for example, beta is 30 degrees, 50 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 150 degrees, and the like. Preferably, 85 DEG.ltoreq.beta.ltoreq.95°. Fig. 59C schematically illustrates that the translational coupling 231 is subjected to a first magnetic force Fa from the translational driving member 321, and the rotational coupling 232 is subjected to a second magnetic force Fb from the rotational driving member 322, with an angle β therebetween.

As shown in fig. 60 to 62, the transmission assembly 300 may further include a transmission support 330, a mounting bracket 340, and a rotation driving device 301. The drive mount 330 can be positioned within the body central bore 313 and coupled to the drive body 310. The drive body 310 can be rotatable relative to the drive mount 330. The mounting bracket 340 is located above the drive body 310 and is capable of being coupled to the drive mount 330, for example, by fasteners such as screws. The rotation driving device 301 can be provided to the mounting bracket 340, and an output shaft thereof is connected to the transmission body 310 to rotate the transmission body 310. In the present embodiment, the mounting bracket 340 supports the rotation driving device 301 upward, and the rotation driving device 301 can move in a straight line together with the transmission body 310, so that the charged rotation driving device 301 can be disposed at a position other than the pot cover 4.

In particular, 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 feed bin 110 moves between the first position and the second position, the stand support surface 332 abuts against the linkage support surface 131, so that the transmission assembly 300 can move smoothly. The stand support surface 332 is separated from the linkage support surface 131 when the feed bin 110 moves between the second position and the additional position.

The abutment support surface 332 can be adapted to the shape of the coupling support surface 131, and can be configured, for example, as a vertically inclined surface, optionally as 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 bore 331 is located in the center of the drive carrier 330. The feed bin 110 can be located within a pedestal central bore 331 with a pedestal support surface 332 disposed about the pedestal central bore 331. The top of the driving body 310 can be located between the holder boss 333 and the mounting bracket 340, which can limit the movement of the driving body 310 in a straight line with respect to the driving holder 330.

The top of the driving body 310 may be provided with an upwardly protruding gear portion 314, the gear portion 314 surrounding the support center hole 331 and having a ring of teeth. The output shaft is provided with a transmission gear 302, the teeth of the transmission gear 302 being meshed 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 transmission gears 302 is not limited, and may be set to two or more as needed.

The mounting bracket 340 may be provided with a bracket guide 341, the bracket guide 341 extending in the vertical direction. Referring back to fig. 52, the storage bin 13 may be correspondingly provided with a vertically extending guiding wall 102, at least a portion of the guiding wall 102 being located inside the storage bin 13 in connection with a fixed bracket 122 for spacing the transmission structure from the space in which the food material is stored. Fig. 52 schematically shows that the guide wall 102 is connected to the bottom wall of the storage bin 13, partly above the bottom wall and partly extending downwards from the bottom wall. The bracket guide 341 is located in the slide passage 46 surrounded 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 bracket base 342 may be provided with a bracket guide 341 integrally formed therewith. The bracket guide 341 may include, for example, three walls connected in sequence, and the bracket stand 343 is located in a substantially square area surrounded by the three walls. And the bracket stand 343 is detachably connected to the bracket base 342 by a fastener such as a screw. The rotation driving device 301 is mounted to the bracket stand 343 and also located in the bracket guide 341. The middle part of the stand 343 is provided with a stand portion in which the output shaft of the rotation driving device 301 is located. The lower end of the barrel portion abuts the drive gear 302 to limit axial movement of the drive gear 302.

As shown in fig. 47, 50, 63, and 64, the first rotation axis Ax1 may be collinear with the second rotation 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 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 rotating fitting 232 may be provided in plurality at intervals along the circumferential direction of the mount 240, specifically, along the circumferential direction of the second mount 250. The rotation driving part 322 is provided in plurality at intervals along the circumferential direction of the transmission body 310. The plurality of rotation fittings 232 have the same magnetism and are arranged centrally symmetrically about the first rotation axis Ax 1. The plurality of rotation driving pieces 322 have the same magnetism and are arranged centering symmetrically around the second rotation axis Ax 2. The plurality of rotary fittings 232 are uniformly arranged along the circumferential direction of the mounting seat 240; the plurality of rotary drivers 322 are uniformly disposed along the circumferential direction of the transmission body 310. Thus, the magnetic forces applied to the second mount 250 in the circumferential direction can be equalized and applied uniformly, and the first rotation axis Ax1 and the second rotation axis Ax2 can be kept collinear. The magnetic properties of the plurality of rotating fittings 232 may also be different, but the number of rotating fittings 232 of different magnetic properties need to be equal. Preferably, the rotating matching pieces 232 with different magnetism are also uniformly and alternately arranged on the premise of equal number, for example, a group of rotating matching pieces with first magnetism is firstly arranged, a group of rotating matching pieces with another magnetism is arranged, a group of rotating matching pieces with first magnetism is then arranged, a group of rotating matching pieces with second magnetism is then arranged, and thus repeated interval arrangement is performed, the rotating matching pieces with two adjacent groups are ensured to have different magnetism but same number, the number of magnets in each group is the same, and the number of magnets is greater than or equal to 1, and the rotating matching pieces can be flexibly arranged according to the requirement, for example, the number of magnets can be two, three, four, five or six. For example, the total number of rotating fittings 232 may be two and evenly arranged, with one magnet facing outward being N-pole and the other magnet facing outward being S-pole. The number of rotary drives corresponding thereto may be two. Or as shown in fig. 64, the rotating matching piece has 4 groups, each group has 3 magnets, wherein the outward magnetic poles of one group of 3 magnets are all set as N poles, the outward magnetic poles of the adjacent group of 3 magnets are all set as S poles, and the outward magnetic poles of the rotating matching piece are NNN, SSS, NNN, SSS respectively. Correspondingly, the magnetic properties of the plurality of rotary driving members 322 are different, but the same number is required to be arranged uniformly and at intervals. For example, as shown in fig. 64, the total number of the rotary driving members is 16, the rotary driving members may be set to 4 groups, wherein each of the outwardly-facing magnetic poles of one group of 4 magnets is set to N-pole, each of the outwardly-facing magnetic poles of the adjacent 4 magnets is set to S-pole, and the outwardly-facing magnetic poles of the rotary driving members are NNNN, SSSS, NNNN, SSSS. When rotating, the outward magnetic pole is NNNNN group rotary driving piece and the outward magnetic pole is SSS group rotary matching piece to generate magnetic force, and the outward magnetic pole is SSSS group rotary driving piece and the outward magnetic pole is NNN group rotary matching piece to generate magnetic force. Thus, the second mount 250 can be uniformly stressed by the same magnetic force in the circumferential direction.

The wash bin assembly 200 may also include a stop feature. The mount 240 rotates around the limiting member, and the limiting member abuts against the surface of the mount 240 opposite to each other. In this embodiment, the second mounting seat 250 drives the first mounting seat 220 to rotate around the limiting component, and the limiting component includes an inner sidewall 214 and an outer sidewall 215 of the washing bin main body 210.

The transmission body 310 is configured in a center symmetrical shape, particularly a turntable shape as described above. Mount 240 is configured in a center-symmetrical shape. Specifically, the first mount 220 and the second mount 250 are each cylindrical in shape. In this embodiment, as described above, the mounting seat 240 and the stirring member 19 may be separate members, specifically, the first mounting seat 220 and the stirring member 19 are separate members, so as to facilitate the installation of the washing bin cover 270.

As shown in fig. 63, when the transmission body 310 is located at the first driving position and the second driving position, that is, when the rotation driving piece 322 is at the driving position, the rotation driving piece 322 corresponds to the position of the rotation mating piece 232 in the radial direction, and the magnetic poles facing each other are opposite. At this time, the magnetic force between the rotation driving member 322 and the rotation matching member 232 is a magnetic attraction force, and the stirring member 19 is rotated by the magnetic attraction force. As shown in fig. 64, the rotary drive element 322 is radially offset from the rotary counter element 232 in the drive position and has the same magnetic poles facing one another. At this time, the magnetic force between the rotation driving tool 322 and the rotation matching tool 232 is a magnetic repulsive force, and the stirring tool 19 is rotated by the magnetic repulsive force.

The rotation driving parts 322 are arranged in plurality at intervals along the circumferential direction of the transmission body 310. The drive sidewall 312 has a plurality of drive mounting surfaces 315 (fig. 52) arranged in a circumferential direction, the drive mounting surfaces 315 being planar and extending vertically, and the rotary drive 322 being mounted to the drive mounting surfaces 315. The rotary fitting 232 is arranged 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, and the rotary fitting 232 being mounted to the mount mounting surfaces 253. One of the rotary fitting 232 and the rotary driving member 322 may be arranged in one row, and the other of the two is arranged in two rows at a vertical interval. Alternatively, the rotary fitting 232 and the rotary driving piece 322 may each be provided with a row, and one of them may be an elongated shape arranged vertically.

The entire washing operation of the cooking appliance 1 of the second embodiment will be described with reference to fig. 44 to 51 as follows:

as shown in fig. 44, the cooking appliance 1 is in an initial state. At this time, the feed bin 110 and the transmission assembly 300 are both in the initial position in the first position, the feed bin 110 is not communicated with the outlet of the storage bin 13 and the feed inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is in the closed position. In the initial state, the stress relation of the material washing bin cover 270 is that F1+F2 is more 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 the magnetic force between the holding member 237 and the holding engagement member 238; g1 is the total weight of the washing bin cover 270 and the follower load moving along a straight line therewith, and in this embodiment, the follower load includes at least the first mount 220, the translational matching member 231, and the stirring member 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, F2, and G2 are variable values. In this state, F1 is small, possibly even close to or equal to 0, when f1=0, f2 is not less than g1+g2; f2max, i.e. F2max; g2 Either =0, or G2 is the weight of a small amount of residual water after washing on the wash chamber 211.

When the discharging operation is intended, first the linear driving device 120 may drive the screw 121 to act, so that the screw 121 may drive the feed bin 110 to move down to the first driving position in the second position. As shown in fig. 45, the cooking appliance 1 is in a ready-to-discharge state. At this time, the feed bin 110 and the transmission assembly 300 are both in the first driving position in the second position, the feed bin 110 is not communicated with the outlet of the storage bin 13 and the feed inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is still in the closed position. In the state shown in fig. 45, the force relationship of the cartridge cover 270 is f1+f2> g1+g2, where F1 and F2 are the largest, i.e., F1max, F2max, G2 are the same as in the initial state. Thus, the cartridge cover 270 is magnetically coupled in an upward direction and there is a magnetic coupling in a radial direction of the cartridge assembly 200. The linear driving device 120 can continue to drive the screw 121 to act, and the feeding bin 110 continues to move downwards and extend into the material washing cavity 211 without the transmission assembly 300 moving along with the feeding bin. As shown in fig. 46, the cooking appliance 1 is in a blanking state. At this point the feed bin 110 is in the additional position, the transmission assembly 300 is in the first drive position in the second position, the feed bin 110 is still in communication with both the outlet of the storage bin 13 and the feed inlet 201 of the wash bin assembly 200, and the wash 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 material washing cavity 211 through the discharging hole 112 to perform the discharging action. The amount of material flowing into the wash chamber 211 may be calculated by time, and the cooking appliance controls the time when the feed bin 110 is in the additional position according to the amount of material required by the user, to achieve quantitative discharging. In this blanking state, water may be supplied to the material washing chamber 211, and blanking and water supply may be performed at the same time, or water supply may be performed after blanking is completed. The clean water in the clean water tank 81 enters the feed bin 110 through a pipeline and the water inlet 113, and then enters the material washing cavity 211 through the water outlet 114. When the discharging and water supplying are completed, the stress relation of the material washing bin cover 270 is that F1+F2> G1+G2, wherein F1 and F2 are F1max and F2max, and G2 is the weight of water and materials.

When the discharging operation is completed, the linear driving device 120 drives the screw 121 again, and the screw 121 drives the feeding bin 110 to move upwards to the first driving position in the second position, as shown in fig. 47. In the state shown in fig. 47, water may be supplied to the wash chamber 211, or water may be supplied to the wash chamber in the state shown in fig. 46. When water is supplied in the state shown in fig. 47, the weight of G2 increases. After the water supply is completed, the rotary driving device 301 can drive the transmission main body 310 to rotate, and then the magnetic force between the rotary driving piece 322 and the rotary matching piece 232 can drive the second mounting seat 250 to rotate, and then drive the first mounting seat 220 and the stirring piece 19 thereon to rotate together so as to perform the material washing action. It will be appreciated that for the illustrated embodiment, the water level in the wash chamber 211 is lower than the highest portion of the drain pipe 10 when the wash action is performed. In other embodiments, not shown, a separate solenoid valve for opening and closing the drain 213 may be provided, and whether or not to drain water is directly controlled by directly controlling the opened and closed state of the solenoid valve, which may not limit the water level in the wash chamber 211 to be lower than the highest portion of the drain pipe.

For the illustrated embodiment, when the washing operation is completed and the water is intended to be discharged, 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 drain pipe 10, and the water is discharged using the siphon principle. And the highest position of the drain channel will have a velocity head, thereby creating a full flow of the drain 10. When the water level drops below the highest position of the drain pipe 10, the drain channel is already in a full flow state, and at this time, the water level in the material washing cavity 211 is higher than the water level of the water outlet 114 of the drain pipe 107, and at this time, the outlet of the drain pipe 107 has a speed water head according to the Bernoulli principle, so that the water in the material washing bin can be drained completely. When the water discharge is completed, the stress relation of the material washing bin cover 270 is that F1+F2> 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. Clear water may also be added after draining for cooking if desired; in this case, G2 is the weight of the water and the material after water absorption.

The actions of water supply, material throwing and water drainage during material washing can be repeatedly executed, and repeated material washing of single material is realized.

When the discharging operation is completed and the discharging is intended, the linear driving device 120 drives the feed bin 110 to move upward to an intermediate position in the first position, as shown in fig. 48. In the state shown in fig. 48, the force relationship of the flushing bin cover 270 is f1+f2< g1+g2, where F1 is reduced, i.e., F1< f1max, F2 is F2max, and G2 is the same as when the water discharge is completed. Because f1+f2< g1+g2, the sink cap 270 is unbalanced in force and cannot remain in the closed position, will move downward and the discharge port 212 will open. The cooking appliance is quickly switched from the state shown in fig. 48 to the state shown in fig. 49, i.e., the tub cover 270 is moved downward to the open position, and the process F1 is continued to decrease, and F2 is decreased. As shown in fig. 49, the wash bin cover 270 has been in the open position and the discharge port 212 has been opened. At this point, some material and/or water falls into the inner pan 3, reducing G2. In the state shown in fig. 49, the force relationship of the bin cover 270 is f1+f2< g1+g2, wherein F1< f1max, F2 is the smallest, i.e., F2min, and G2 is the weight of the remaining water-absorbing material and a small amount of residual water. The linear drive 120 then moves the screw 121 downwardly from the intermediate position to a second drive position of the second positions. At this time, as shown in fig. 50, the cooking appliance 1 is in a blanking state. The distance d1 is between the translational driving piece 321 and the translational matching piece 231, and the stress relation of the bin cover 270 is f1+f2< g1+g2, wherein F1< F1max, F2 is F2min, and G2 is the same as that shown in fig. 49, so that the bin cover 270 is always kept at the open position during blanking. 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, and the material is quickly dropped into the inner pot 3 under the action of centrifugal force. And G2 continues to decrease during material throwing, and after the material throwing is completed, the stress relation of the material washing bin cover 270 is F1+F2< G1+G2, wherein F1< F1max and F2 are F2min, and G2 is the weight of a small amount of residual water. As an example, the difference between f1+f2 and g1+g2 at this time may be 30G.

When the blanking action is completed and the resetting is required, the linear driving device 120 continues to drive the screw 121 to move the transmission main body 310 from the second driving position to the first driving position, as shown in fig. 51, the process F1 increases, the distance d2 between the translational driving member 321 and the translational matching member 231 is smaller than d1, the force relationship of the bin cover 270 is f1+f2> g1+g2, where F1 is F1max, F2 is F2max, and G2 is the weight of a small amount of residual water, so that the bin cover 270 will be moved upwards to the closed position by the magnetic force, for example, as shown in fig. 45, to reset the bin cover 270. The cooking appliance is quickly switched from the state shown in fig. 51 to the state shown in fig. 45, i.e. the tub cover 270 is moved up to the closed position, the process F1 continues to increase to F1max, F2 increases to F2max, G2 is the same as in fig. 51, at which time f1+f2> g1+g2.

Each action in the blanking process can be repeatedly executed, so that the material washing of multiple materials is realized; i.e., repeatedly executing the states shown in fig. 45 to 51.

The linear drive 120 then moves the feed bin 110 upward to an initial position in the first position, as shown in fig. 44, to effect a reset of the feed bin 110 and the drive assembly 300. This process F1 is reduced to a smaller, possibly even near or equal to 0, F2 is F2max, G2 is the same as in fig. 51, where f1+f2> g1+g2.

It will be appreciated that in other embodiments, not shown, the wash bin cover 270 may be in an open position in an initial state. In other words, when the cooking appliance 1 is not operated, the discharge port 212 may be in a normally open state, i.e., the washing tub cover 270 is in an open position in an initial state. Specifically, the remaining structure is the same as that of the cooking appliance of the illustrated embodiment except for the elimination of the holding member 237 and the holding engagement member 238, and only the differences will be described in detail herein for the sake of brevity. Specifically, the sink assembly 200 does not include the retaining member 237 and the retaining engagement member 238, i.e., there is no F2, F2 being the magnetic force between the retaining member 237 and the retaining engagement member 238. So in the initial state, at this time, the feed bin 110 and the transmission assembly 300 are both in the initial position in the first position, the feed bin 110 is not communicated with the outlet of the storage bin 13 and the feed inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is in the open position.

In an initial state, the force relationship of the washing bin cover 270 is f1< g1+g2, in which state F1 is small, possibly even 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 chamber 211. When the discharging operation is intended, the cover 270 of the washing bin needs to be moved from the open position to the closed position, that is, the linear driving device 120 can drive the screw 121 to act, so that the screw 121 can drive the feeding bin 110 to move downwards to the first driving position (as shown in fig. 3) in the second position. At this time, the force relation of the washing bin cover 270 is f1> g1+g2, and the washing bin cover 270 moves to the closed position under the action of magnetic force.

The other operations of the discharging operation, the washing operation, the draining operation, the blanking operation, and the water supply operation are the same as those of the cooking device of the illustrated embodiment, except that the magnetic force received by the washing bin cover 270 is F1, and the magnetic force of F2 is not f1+f2, that is, the magnetic force of the washing bin cover 270 is not present, but the force magnitude relation between the discharging stage, the washing stage, the draining stage, the blanking stage, and the g1+g2 is identical to the force magnitude relation between the cooking device of the illustrated embodiment in the same stage, and the operation actions of the linear driving device 120 and the rotation driving device 301 are identical. Taking the blanking stage as an example, for the embodiment in which the discharge port 212 is in a normally open state, the stress relationship of the bin cover 270 is f1> g1+g2; for the illustrated embodiment, the force relationship of the wash bin cover 270 is f1+f2> g1+g2. The magnetic force of the blanking stage of the two embodiments is larger than G1+G2, namely the magnitude relation is consistent. The difference is that the washing tub cover 270 does not need to be reset after the blanking operation is completed, i.e., the washing tub cover 270 is maintained in an opened state, and the linear driving device 120 drives the feeding tub 110 to move upward to an initial position in the first position, and the washing tub cover 270 is maintained in an opened state.

Furthermore, in other embodiments not shown, both the translational and rotational fittings 231, 232 are located inside the wash chamber 211. When the rotary driver 322 is in the driving position, i.e. when the transmission body 310 is in the first driving position and the second driving position, the rotary driver 322 is located radially inward of the rotary fitting 232. Therefore, the external structure of the cooking utensil is simple, and the miniaturization of products is facilitated; and the structure of the transmission assembly 300 may be simpler.

As an example, a cylindrical mount inside the wash chamber 211 may be included. The washer housing 270 and the stirring member 19 may each be connected to the mount. The rotary fitting 232 and the movable fitting 231 are provided to the mount. The washing bin body 210 is provided with a trough portion inside the washing chamber. The slot body portion forms a receiving slot for receiving the translational drive 321 and the rotational drive 322, and more particularly the transmission body.

It should be noted that, the stress relationship mentioned herein may be understood as the stress relationship of the assembly formed by the bin cover 270 and the follow-up load moving along the straight line along with the bin cover 270, and for brevity, the stress relationship is simply referred to as the stress relationship of the bin cover 270; similarly, the description herein of the forces of magnetic force, magnetic force, gravity, etc., used to describe the washing silo cover 270 may be understood to be various descriptions of the forces of the washing silo cover 270 and the follower load moving along a straight line therewith, and for brevity, the washing silo cover 270 is simply replaced with the washing silo cover 270, as an example, the washing silo cover 270 is magnetically understood to be the components of the washing silo cover 270 and the follower load moving along a straight line therewith.
