That is, in this embodiment, the trapway 10' does not include an annular first conduit.

Alternatively, the highest water level of the waste tank may be lower than the lid. Therefore, the sewage discharge pipeline which is arranged in the pot cover and used for preventing too much water in the sewage tank from flowing back can be avoided, and sewage is prevented from entering the inner pot.

In a preferred embodiment, the live parts (such as the motor, the heating device, the temperature measuring device, etc.) in the cooking appliance are all arranged on the machine body and the pot body, so that the pot cover has no live parts, the pot cover can be manufactured without considering water resistance and can be cleaned more conveniently, when the pot cover is detachable from the pot body, the pot cover can be detached and cleaned independently, and the pot cover can be washed under a water tap or cleaned in a basin due to the fact that the pot cover has no live parts. Or the electrified components are all arranged on the machine body, so that the pot cover and the pot body have no electrified components. The pot cover and the pot body are both provided with no electrified part, so that the whole body does not need to consider water resistance, and even the pot cover and the pot body can be placed under a water tap for washing.

Referring back to fig. 1, the cooking appliance 1 further comprises a water inlet assembly for supplying water to the washing chamber. The water inlet assembly may include a clean water tank 81 and a water inlet pipe (not shown). The outlet of the clean water tank 81 can communicate with the inlet 113 of the feeding bin 16 via a water inlet pipe and between them, for example, an electrically controlled valve can be arranged to control the inlet of water. The clean water in the clean water tank 81 can automatically flow to the feeding bin 16 through the difference between the high and low water levels, or can be conveyed to the feeding bin 16 through a water pump. The clean water tank 81 is detachably provided on the body assembly 11 so that a user can conveniently perform a water adding operation. The clean water tank 81 is disposed near the stock mechanism 89 and above the dirty water tank 48. The water inlet pipe may be located in the magazine 89. To the scheme of setting up the water pump, the water pump may also be located in the storage mechanism 89.

As shown above, the feeding mechanism 15 is used for conveying the food material in the storage mechanism 89 to the washing cavity. The magazine mechanism 89, the feed mechanism 15 and the drive assembly may all be located on a first side of the main frame 101 and above the wash bin assembly 5. Due to the arrangement, the feeding mechanism 15 can be close to the material storage mechanism 89, the space is occupied, materials can automatically enter the material washing cavity through the feeding mechanism 15 by utilizing gravity, additional driving devices such as a feeding pump and the like and feeding pipelines are not needed, the cost is reduced, the structure of the cooking appliance 1 is simplified, and the product miniaturization is facilitated; the transmission assembly can drive the stirring piece 19 from the upper part of the material washing cavity, so that an electrified driving device can be arranged at a position outside the pot cover 4, and a user can conveniently clean the pot cover 4 and the material washing bin assembly 5.

The water intake assembly and the soil exhaust assembly may be disposed on a second side of the main frame 101 different from the first side. Fig. 1 shows that the first and second sides of the main chassis 101 face away from each other. The clean water tank 81 may correspond to the sewage tank 48 in the up-down position, i.e., the clean water tank 81 is positioned right above the sewage tank 48. The clear water in the clear water tank 81 can automatically flow to the feeding bin through the difference of the height and the height of the water without arranging a pressurized water pump. The main frame 101 may be provided with a first accommodation seat 103 and a second accommodation seat 104 located above the first accommodation seat 103. The clear water tank 81 is removably disposed in the first receiving seat 103, so that a user can conveniently perform a water adding operation. The waste water tank 48 is removably installed in the second receiving seat 104, so that a user can conveniently pour water.

As shown in fig. 2, the cooking appliance 1 may further include a main board 90 and a display board 91. The display panel 91 may be provided at the stocker mechanism 89, and the outer side of the display panel 91 may be provided with a control panel 92. The main board 90 may be provided within the main chassis 101. The main plate 90 is positioned above the dirty water tank 48 and on the side of the clean water tank 81 facing the pan body 2. The waste tank 48 may be provided with a top opening to receive waste and pour water from the waste pipe. The main frame 101 may be provided with a partition 93, and the partition 93 may partition the main board 90 and the sewage tank 48 to prevent the sewage from splashing to the main board 90 to be damaged. The partition 93 may be a part of the first receiving seat 103. The partition 93 may be provided with a wiring hole to route the wiring to the bottom of the main chassis 101. In an embodiment not shown, the main chassis 101 may form an accommodation cavity having an opening at a first side. The pot body 2 and the lid 4 are removably placed in the receiving cavity.

The feeding mechanism 15 may be movably arranged between a storage position and an engagement position. The feeding mechanism 15 is located at a storage position (shown in fig. 2) in an initial state and is at least partially stored in the storage cavity of the cooking appliance 1. The feed mechanism 15 is in an engaged position (as shown in figure 3 for example) and is moved out of the receiving cavity in the operating condition. The stocker mechanism 89 and/or the main chassis 101 may be provided with a storage chamber. For the illustrated embodiment, the magazine mechanism 89 is provided with a housing cavity. The feeding mechanism 15 can be completely accommodated in the accommodating cavity so as to hide the feeding mechanism 15 in the material storing mechanism 89. The slide channel 46 forms part of the receiving chamber. The storage position here is the first position, and the engagement position includes at least a second position and a third position.

As mentioned above, the feed mechanism 15 can be engageable with the drive assembly, both of which are combined as a single unit. For the illustrated embodiment, a portion of the drive assembly is disposed within the feed mechanism 15. The transmission assembly can be connected with the stirring piece through the shaft connecting structure. For the illustrated embodiment, the shaft connecting structure may include the sliding shaft 25, the transmission shaft 26, the connecting shaft 27, and the rotating shaft 33 described above. The transmission assembly may be movably disposed between a stowed position (as shown in fig. 2) and a mated position (as shown in fig. 3, for example). The transmission assembly is located at the storage position in the initial state and can be at least partially stored in the storage cavity of the cooking appliance 1. The transmission assembly is located at the matching position in the working state and is moved out of the containing cavity. For the illustrated embodiment, the drive assembly can be fully received in the receiving cavity of the magazine 89 to hide the drive assembly in the magazine 89. And the drive assembly can be moved out of the receiving cavity together with the feeding mechanism 15 to the mating position.

When the cooking appliance 1 is in the initial state, one of the feeding mechanism 15 and the transmission assembly is closer to the wash bin assembly 5, in particular the wash bin main body 52, than the other of the feeding mechanism 15 and the transmission assembly. One of the feeding mechanism 15 and the transmission assembly is spaced apart from the washing bin assembly 5 by a distance D. In the illustrated embodiment, when the cooking appliance 1 is in the initial state, the feeding bin 16 of the feeding mechanism 15 is closer to the washing bin main body 52 of the washing bin assembly 5 than the transmission shaft 26 of the transmission assembly, and the feeding bin 16 and the washing bin main body 52 have a spacing distance D therebetween. The separation distance D is 5mm to 100mm, for example, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100 mm.

The whole working process of the cooking appliance 1 according to the preferred embodiment is described below with reference to fig. 2-7:

as shown in fig. 2, the cooking appliance 1 is in an initial state. At the moment, 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 feeding port 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 feeding bin 16 to move downwards to the second position. As shown in fig. 3, the cooking appliance 1 is in a blanking state. 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 discharging state, the feeding hole 88 can be communicated with the outlet 14 of the storage bin 13, and the discharging hole 82 can be communicated with the feeding hole 7 of the washing bin assembly 5, so that the material in the storage bin 13 enters the feeding bin 16 through the feeding hole 88 and then enters the washing bin assembly 5 through the discharging hole 82. The amount of material flowing into the wash chamber can be calculated by time.

When the blanking operation is completed, the first driving device 21 drives the first transmission device to move, 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 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 wash bin assembly 5. According to the scheme, the third position is arranged, so that the stroke of the up-and-down movement of the transmission shaft 26 can be divided into sections to the feeding bin 16, the movement stroke of the transmission shaft 26 can be reduced, and the phenomenon that the transmission shaft 26 is too long is avoided.

When a washing operation is intended, as shown in fig. 5, 13 and 14, the third driving device 28 can drive the first gear 29 to rotate, the first gear 29 drives the second gear 30 to rotate, the second gear 30 drives the transmission screw 31 to move downwards, and the transmission shaft 26 also moves downwards along with the transmission screw 31 to be engaged with the connecting shaft 27 of the washing bin assembly 5 because the transmission screw 31 is sleeved outside the transmission shaft 26. The second drive means 24 can now be opened so that the second drive means 24 drives the transmission shaft 26 in rotation, so that the transmission shaft 26 can drive the connection shaft 27 in rotation. When the connecting shaft 27 is rotated, the rotating shaft 33 engaged with the connecting shaft 27 and the stirring piece 19 may be rotated, so that the washing operation may be performed. It will be appreciated that the washing stock cover 17 is located above the discharge outlet 9 when the washing operation is performed.

When the washing operation is completed with the intention of draining, the third drive 28 can be opened to drive the drive screw 31 downwards, the drive screw 31 pushing the shaft 33 downwards, so that the stirring element 19 can be moved downwards. When the stirring element 19 moves downwards to the position where the washing bin cover 17 moves below the sewage discharge outlet 9, as shown in fig. 6, the third driving device 28 is controlled to stop, and at this time, the sewage in the washing cavity can flow to the sewage discharge pipeline 10 and the sewage tank 48 through the sewage discharge outlet 9.

When the draining is completed and the blanking operation is desired, the third driving device 28 is controlled to be opened to drive the transmission screw 31 to continue moving downwards, and the transmission screw 31 pushes the rotating shaft 33 downwards, so that the stirring piece 19 can be moved downwards to be away from 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 the washed materials are thrown into the inner pot 3.

When the blanking operation is completed, the third driving device 28 may drive the drive screw 31 to move upward, and after the drive screw 31 moves upward into the feed bin 16, the first driving device 21 may drive the feed bin 16 to return to the first position. The rotation shaft 33 and the stirring member 19 connected thereto can 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, and the cleaning process of the whole cooking utensil 1 is simplified.

Embodiment mode 2

Hereinafter, a cooking appliance according to a second preferred embodiment of the present invention will be described in detail with reference to the drawings, and the cooking appliance according to the second preferred embodiment has substantially the same structure as 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 includes a transmission assembly 300, and the transmission assembly 300 can be linearly movably disposed. Specifically, the drive assembly 300 can be engaged with the feed bin 110 to move the drive assembly 300 with the feed bin 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 part of the washing bin assembly 200 to rotate, in this embodiment, the transmission assembly can at least rotate the washing bin cover 220 to complete the washing and throwing processes; and can drive the stirring piece 240 to move between the opening position and the closing position together with the washing bin cover 220 so as to complete the processes of blanking and draining.

The following describes in detail the transmission structure among the feeding mechanism 100, the transmission assembly 300 and the washbin assembly 200 with reference to the drawings.

The feeding mechanism 100 may be connected to the driving assembly 300 by means of a contact type driving. The transmission assembly 300 may be coupled with the washing bin assembly 200 by magnetic force generated by a magnetic member, and a contactless transmission may be configured between the transmission assembly 300 and the washing bin assembly 200. In this embodiment, the wash bin cover 220 may be in a closed position or an open position in an initial state. In other words, when the cooking appliance 1 is not in operation, the discharge opening 212 may be in a normally closed state or a normally open state.

In the present embodiment, the stirrer 240 is connected to the washer tub cover 220, and the stirrer 240 is not connected to other components. The wash bin cover 220 can drive the agitator 240 to rotate together when in both the open and closed positions. The stirrer 240 is movable between an open position and a closed position together with the washer bin cover 220, and the stirrer 240 is rotatable together with the washer bin cover 220. When the stirring member 240 rotates, the washing bin cover 220 also rotates.

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. 46, the feed magazine 110 is movable relative to the feed magazine 110 and has additional positions. The feed bin 110 is closer to the wash chamber 211 in the additional position. The feeding bin 110 is not communicated with the storage bin 13 and the washing cavity 211 in the first position and the second position. When the feed bin 110 is moved to the additional position, the drive 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 at the moment, the feeding bin 110 can be communicated with both the storage bin 13 and the washing cavity 211. In this embodiment, the feeding bin 110 has a dual stage motion relative to the transmission assembly 300, which can move together with the transmission assembly 300 or separate from it, so that the feeding bin 110 can enter or leave the washing chamber 211, facilitating the feeding and terminating the feeding.

The wash bin assembly 200 is located below the drive assembly 300. When the feeding bin 110 is in the additional position, the transmission assembly 300 may abut against the top surface of the wash bin body 210, such that the transmission assembly 300 can stop moving when the feeding bin 110 moves from the second position to the additional position.

As shown in fig. 52-54, 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 connecting structure 117, the link 130 is provided with a structure matched with the rotary connecting structure 117, and the link 130 is rotated to be connected to the rotary connecting structure 117. And the link 130 is fixed to the rotational connection structure 117 with a screw. The transmission body 310 is provided with a body center hole 313, and it is understood that the body center hole 313 is located at the center of the transmission body 310. The feed bin 110 is located within the central body bore 313.

The link 130 is located at a lower side of the transmission body 310 and is provided with an upward-facing link supporting surface 131 for supporting the transmission assembly 300 upward. By means of the linkage support surface 131, the feeding bin 110 can drive the transmission assembly 300 to move upwards. For the illustrated embodiment, the transmission assembly 300 may move downward with the feed bin 110 as it moves downward by its own weight. The linkage support surface 131 may be configured as a slope inclined in the vertical direction, and the illustrated embodiment shows the linkage support surface 131 as a conical surface having a circular shape, specifically, inclined outward from top to bottom in the radial direction of the linkage 130. Therefore, rapid blanking can be facilitated, and the phenomenon of blockage at the bottom of the feeding bin 110 is avoided.

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 the output shaft of the linear drive 120 and is located within the screw hole 115. When the output shaft rotates, the screw 121 can move within the screw hole 115 relative to the feeding bin 110, thereby moving the feeding bin 110 up and down.

The feeding mechanism 100 further includes a fixing bracket 122, a fixing seat 123 and a fixing pressure plate 124. The fixing brackets 122 are located within the storage bin 13 and can be connected to the storage bin 13, for example, as an example, the inner bottom surface of the storage bin 13 can be provided with upwardly extending studs (not shown), the fixing brackets 122 can be spaced apart with screw bosses 126 having through holes through which screws can be tightened to the studs, whereby the fixing brackets 122 can be mounted to the storage bin 13. The fixed bracket 122 can be provided with a receiving cavity with an opening facing downwards, and the linear drive device 120 is connected to the fixed bracket 122 and located in the receiving cavity. Specifically, the linear driving device 120 is located in the cavity of the fixing base 123, and the fixing base 123 is accommodated in the receiving cavity. The cavity is adapted to the shape of the linear drive 120 to limit the rotational and vertical movement of the linear drive 120. The fixed pressure plate 124 is located at the opposite side, i.e., the lower side, of the linear driving device 120 from the fixed base 123. The fixed pressing plate 124 may be connected to the fixing base 123, for example, the fixed pressing plate 124 and the fixing base 123 are provided with screw holes, the fixing bracket 122 is provided with screw posts 127 extending downward, and screws are passed through the screw holes of the fixed pressing plate 124 and the fixing base 123 and locked to the screw posts 127. The end of the screw 121 is clamped between the fixed platen 124 and the fixed base 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 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.

As shown in fig. 44, the wash tank assembly 200 further includes a wash tank fitting 230. A wash bin fitting 230 may be connected to the wash bin cover 220. The transmission assembly 300 includes a transmission body 310 and a wash hopper drive 320. The transmission body 310 can be engageable with the feed bin 110. The transmission body 310 is movably arranged and rotatably arranged around a central axis, in particular the transmission body 310 is movable relative to the storage bin 13 and rotatable relative to the feeding bin 110 around a central axis. The tub driving member 320 is provided to the driving body 310, and may be mounted to the driving body 310 by, for example, a screw coupling or the like.

Transmission body 310 has a non-driving position (as shown in FIGS. 48 and 49) for disengaging the washer cartridge mating element 230 from the washer cartridge drive 320, and a driving position for engaging the washer cartridge mating element 230 with the washer cartridge drive 320. Wherein the driving positions include a first driving position (respective states shown in fig. 45 to 47) and a second driving position (blanking state shown in fig. 50). The first drive position corresponds to a closed position and the second drive position corresponds to an open position. Wherein the first position is a non-actuated position that includes an initial position and an intermediate position; the second position may be a drive position and include a first drive position and a second drive position. Further, when the transmission body 310 is located at the first position, the wash hopper driving member 320 is disengaged from the wash hopper fitting member 230. When the transmission body 310 is in the second position, the wash hopper drive 320 is coupled with the wash hopper fitting 230. The intermediate position is located between the initial position and the second drive position. It should be noted that, for ease of understanding, fig. 48 and 51 show an intermediate state during the action, in which the wash bin cover 220 is under an unbalanced force. It should be noted that the correspondence of positions refers to the correspondence existing based on the magnitude of the magnetic force between the washing bin mating member 230 and the washing bin driving member 320, and other additional forces are not considered. For example, the wash bin cover 220 is in the closed position in the initial state by an additional force upwards, such as an additional magnetic force. Specifically, the initial position among the above-described non-driving positions corresponding to the opening position is based on the case where the upward additional force is not considered.

By controlling the up-and-down movement position of the transmission assembly 300, the movement direction of the washing bin cover 220 is controlled according to the change of the resultant force direction of the magnetic force and the gravity, so that the washing bin cover is moved to the opening position and the closing position.

When the transmission body 310 moves, the wash bin cover 220 can move in a straight line between the open position and the closed position under the magnetic force. This can open and close the discharge opening 212. When the washing bin cover 220 is located at the closed position and the open position and the transmission body 310 rotates, the washing bin cover 220 can rotate under the action of magnetic force, and the stirring member 240 also rotates synchronously therewith. Therefore, the actions of washing and blanking can be realized.

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. The non-contact transmission mode of the scheme does not need to clean the transmission structure, and the experience of a user can be improved.

In this embodiment, the feeding bin 110 and the transmission assembly 300 can generate a stroke of synchronous movement, and the transmission assembly 300 and the washing bin cover 220 can generate a matching movement, so that only one driving device for driving the feeding bin 110 to move can be arranged, and three linear movements of the feeding bin 110, the transmission assembly 300 and the washing bin cover 220 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 body 310 to rotate is provided, so that the material washing and blanking actions can be realized.

The wash bin fittings 230 may include a translation fitting 231 and a rotation fitting 232. The wash bin drive 320 may include a translational drive 321 and a rotational drive 322. Both the translational drive member 321 and the translational mating member 231 are magnetic members, and a magnetic force may exist between the two. The translational drive member 321 is used for cooperating with the translational mating member 231 to move the washing bin cover 220 in a straight line, and the rotary drive member 322 is used for cooperating with the rotary mating member 232 to rotate the washing bin cover 220.

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, an iron block, a nickel block and a cobalt block. 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 or cobalt blocks, ferritic steel, martensitic steel, austenitic-ferritic dual phase steel, and the translation drive member 321 is a magnet. Because the magnetism of the iron block, the nickel block or the cobalt block, the ferritic steel, the martensitic steel and the austenite-ferrite dual-phase steel is not influenced by high temperature, the magnetism of the translation fitting 231 can be prevented from being influenced by the 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.

The washing bin assembly 200 is located below the driving assembly 300, and the feeding bin 110, the washing bin cover 220 and the driving assembly 300 are all arranged to move up and down. The translational drive member 321 and the translational mating member 231 are vertically corresponding and have different magnetic poles facing each other. When the transmission body 310 is in the first and second driving positions, the rotary drive member 322 corresponds to the rotary counterpart 232 in radial position and has different magnetic poles facing each other. As shown in fig. 59, the driving body 310 is configured in a shape of a rotating disk 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.

For embodiments that do not include electromagnets, the drive assembly 300 is linearly movable relative to the wash bin body 210. When the transmission assembly 300 is moved to change the magnetic force between the translational engagement member 231 and the translational drive member 321, the wash hopper cover 220 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 220 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, after changing the energization state of the electromagnet, the wash silo cover 220 can move linearly to open and close the discharge opening 212.

The height of the transmission body 310 in the first driving position is lower than that in the second driving position. Further, the first driving position is located above the second driving position. When the transmission body 310 is located at the first driving position, the translational driving element 321 is linked with the translational mating element 231, and the rotary driving element 322 is linked with the rotary mating element 232. When the transmission body 310 is located at the second driving position, the translational driving element 321 is linked with or separated from the translational mating element 231, and the rotary driving element 322 is linked with the rotary mating element 232. For the illustrated embodiment, referring to fig. 50, when the transmission body 310 is located at the second driving position, the translational driving element 321 is coupled with the translational mating element 231, and the magnetic force therebetween is smaller than the gravity of the washing bin cover 220 and the load thereon, which includes the translational mating element 231, the stirring element 240 and other components connected thereto. Whereby the wash bin cover 220 may be maintained in an open position.

Alternatively, the upper end surface of the translation fitting 231 may have an angle α with the side end surface of the rotation fitting 232, wherein α is 90 ° or more and 135 ° or less, for example, α is 90 °, 100 °, 110 °, 120 °, 130 °, 135 ° or the like, so that the magnetic fields generated by the translation fitting 231 and the rotation fitting 232 are independent and do not interfere with each other as much as possible.

In this embodiment, the wash bin fittings 230 can be located outside of 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.

As shown in fig. 55 and 56, the wash bowl cover 220 may include a cover main body 221 and a cover seating 222 connected to the cover main body 221. The cover main body 221 is used to cover the discharge opening 212. The cover body 222 is located at the radial outer side of the material washing cavity 211, and the bottom of the cover body is provided with openings at intervals along the circumferential direction, so that the wet materials fall into the inner pot 3 through the openings when blanking.

The middle part of the support stand 343 is provided with a support section, and the output shaft of the rotary transmission device is located in the support section. The lower end of the fulcrum portion abuts against the transmission gear 302 to restrict the axial movement of the transmission gear 302.

The rotating counterpart 232 and the rotary drive 322 may both be permanent magnets. As with the other magnets mentioned herein, one of the magnets in a pairwise fit may be a permanent magnet and the other may be either a permanent magnet or a soft magnet. For example, one of the translational engagement element 231 and the translational drive element 321 may be a permanent magnet, and the other may be a permanent magnet or a soft magnet. The linear drive 120 and the rotary drive 301 mentioned herein may be motors, for example.

The soil channel 105 communicates the soil outlet 213 and the pipe joint 106, and the soil pipe 107 has one end connected to the pipe joint 106 and the other end extended to the soil tank 48. Alternatively, as in the illustrated embodiment, the waste pipe 10 may include a siphon pipe having an inverted U-shaped structure. As an example, the trapway 105 can be configured in an inverted U-shape as a siphon line.

In this embodiment, the bottom of the feeding mechanism 100 is engageable with the drive body 310 of the drive assembly 300. The storage mechanism is provided with a containing cavity. As shown in fig. 44, when the feeding mechanism 100 is in the storage position, the other parts except the bottom part are stored in the storage cavity, so that most of the feeding mechanism 100 is hidden in the magazine. The slide channel 46 enclosed by the guide wall 102 forms part of the receiving chamber. When the transmission assembly 300 is in the storage position, the rotation driving device 301 can be stored in the storage cavity of the storage mechanism, so as to hide a part of the transmission assembly 300 in the storage mechanism. And the rotary drive 301 of the drive assembly 300 can be moved out of the receiving cavity with the feed mechanism 100 to the engaged position (as shown in fig. 45, for example). The storage position here is an initial position among the first positions, and the engagement position includes at least an intermediate position and a second position among the first positions.

In the present embodiment, when the cooking appliance is in the initial state, the transmission body 310 of the transmission assembly 300 is closer to the wash bin body 210 of the wash bin assembly 200 than the feed bin 110 of the feeding mechanism 100, and the transmission body 310 and the feed bin 110 have a spacing distance D therebetween. The separation distance D may be 5mm to 100mm, for example 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100 mm.

Alternatively, when the washing bin cover 220 rotates, the friction generated by the rotation of the washing bin cover 220 may drive the whole pot cover 4 to rotate, and in order to avoid the pot cover 4 driving the pot body 2 to rotate, as shown in fig. 62 and 63, the outer periphery of the pot cover 4 may be provided with a lug 202 protruding radially outward; correspondingly, the top of the pan body 2 may be provided with a lug groove 203 which is concave downwards, and the lug 202 is positioned in the lug groove 203. Therefore, the movement of the pot cover 4 relative to the pot body 2 in the circumferential direction can be limited, the pot cover 4 can be kept at the initial covering position, and the pot cover 4 is prevented from driving the pot body 2 to rotate. The shape of the lug 202 is adapted to the shape of the lug groove 203. The number of lugs 202 is not limited and may be more than two, and the illustrated embodiment shows two lugs 202 arranged in a circumferentially spaced manner and arranged oppositely. The top of the pot 2 may be provided with an operating part 204 protruding radially outward. The operating portions 204 are preferably arranged in two and opposite positions at intervals in the circumferential direction. The user can grip the operating portion 204 to take the pot 2. The lug groove 203 can be provided to the operating part 204, so that the structure of the pot body 2 can be simplified.

The whole washing operation of the cooking appliance 1 of the second embodiment is described below with reference to fig. 44 to 51:

as shown in fig. 44, the cooking appliance 1 is in an initial state. At this time, the feeding bin 110 and the transmission assembly 300 are both in the initial position of the first position, the feeding bin 110 is not communicated with the outlet of the storage bin 13 and the feeding port 201 of the washing bin assembly 200, and the washing bin cover 220 is in the closed position. In the initial state, the force-bearing relationship of the washing bin cover 220 is F1+ F2 ≥ G1+ G2, wherein F1 is the magnetic force between the translational fitting piece 231 and the translational driving piece 321; f2 is the magnetic force between the retaining member 237 and the retention engagement member 238; g1 is the total weight of the washing bin cover 220 and the follow-up load moving linearly along with it, and in this embodiment, the follow-up load at least comprises the translational matching piece 231 and the stirring piece 19; g2 is the weight of water and material in the wash chamber 211. It is understood that G1 is a fixed value and F1, F2 and G2 are variable values. In this state, F1 is small, possibly even close to or equal to 0, when F1 is 0, F2 ≧ G1+ G2; f2max, i.e., F2 max; g2 is 0, or G2 is the weight of the small amount of residual water after washing in the wash chamber 211.

When the blanking operation is intended, firstly, the linear driving device 120 can drive the screw rod 121 to move, so that the screw rod 121 can drive the feeding bin 110 to move downwards to the first driving position in the second position. As shown in fig. 45, 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 of 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 still not communicated, and the washing bin cover 220 is still located at the closed position. In the state shown in fig. 45, the force relationship of the washing bin cover 220 is F1+ F2> G1+ G2, wherein F1 and F2 are the largest, i.e., F1max, F2max, and G2 are the same as those in the initial state. Thereby, the washer magazine cover 220 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 extend into the washing cavity 211 without the transmission assembly 300 moving therewith. As shown in fig. 46, 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 the outlet of the storage bin 13 and the feeding port 201 of the washing bin assembly 200, and the washing bin cover 220 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 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 relation of the washing bin cover 220 is F1+ F2> G1+ G2, wherein F1 and F2 are F1max and F2max, and G2 is the weight of the water and the materials.

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. 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 rotation driving device 301 may drive the transmission main body 310 to rotate, and then the magnetic force between the rotation driving member 322 and the rotation matching member 232 may drive the second mounting seat 250 to rotate, and further drive the material washing bin cover 220 and the stirring member 19 thereon to rotate together, so as to perform the 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 during the wash action. 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 is lowered to the highest position lower than the sewage pipeline 10, because the drainage channel is already in the full-flow state, at this time, because the water level in the washing cavity 211 is higher than the water level of the water outlet 114 of the sewage pipe 107, according to the bernout principle, the outlet of the sewage pipe 107 has a speed water head, and the water in the washing bin can be drained completely. When the drainage is finished, the stress relation of the washing bin cover 220 is 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. If necessary, clear water can be added after draining for cooking; in this case, G2 is the weight of the 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 is intended to be performed, 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. 48. In the state shown in fig. 48, the force relationship of the washing bin cover 220 is F1+ F2< G1+ G2, wherein F1 is reduced, i.e. F1< F1max, F2 is F2max, and G2 is the same as that when the drainage is completed. Since F1+ F2< G1+ G2 makes the wash bin cover 220 unbalanced in force, it cannot be held in the closed position and will move downward and the discharge opening 212 will be open. The cooking appliance is quickly switched from the state shown in fig. 48 to the state shown in fig. 49, i.e. the washing compartment cover 220 is moved downwards to the open position, and the process F1 continues to be reduced, and F2 is reduced. As shown in fig. 49, the wash bin cover 220 has been in the open position and the discharge opening 212 has been opened. At this point, part of the material and/or water falls into the inner pot 3, and G2 is reduced. In the state shown in fig. 49, the force relationship of the washing bin cover 220 is F1+ F2< G1+ G2, wherein F1< F1max, F2 is the smallest, i.e. F2min, and G2 is the weight of the residual water-absorbing material and the small amount of residual water. The linear driving device 120 drives the screw 121 to move the transmission body 310 downward from the middle position to a second driving 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 provided between the translation driving unit 321 and the translation fitting 231, and the force relationship of the washing bin cover 220 is F1+ F2< G1+ G2, wherein F1< F1max, and F2 are F2min, and G2 is the same as that shown in fig. 49, so that the washing bin cover 220 is always kept at the open position during 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. G2 is continuously reduced during material throwing, and after the material throwing is finished, the stress relation of the washing bin cover 220 is F1+ F2< G1+ G2, wherein F1< F1max, F2 is F2min, and G2 is the weight of a small amount of residual water. As an example, the difference between F1+ F2 and G1+ G2 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 body 310 from the second driving position to the first driving position, as shown in fig. 51, in this process F1 increases, 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 force-bearing relationship of the washing bin cover 220 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 washing bin cover 220 is moved upwards to the closing position under the action of a magnetic force, for example, as shown in fig. 45, the reset operation of the washing bin cover 220 is realized. The cooking appliance is quickly switched from the state shown in fig. 51 to the state shown in fig. 45, i.e. the washing bin cover 220 is moved upwards to the closed position, the process F1 is continuously increased to F1max, the process F2 is increased to F2max, and the process G2 is the same as the state shown in fig. 51, wherein F1+ F2> G1+ G2.

Each action in the process from blanking to blanking can be repeatedly executed, and the material washing for multiple times is realized; that is, the respective states shown in fig. 45 to 51 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. 44, so that the feeding bin 110 and the transmission assembly 300 are reset. This process F1 is reduced to a small, possibly even close to or equal to 0, F2 is F2max, G2 is the same as the state of fig. 51, where F1+ F2> G1+ G2.

It is understood that in other embodiments not shown, the wash bin cover 220 may be in an open position in an 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 220 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 second 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 220 is in the open position.

In the initial state, the force relationship of the washing bin cover 220 is F1< G1+ G2, in this state, F1 is small, and may even be close to or equal to 0, and G2 is 0, or G2 is the weight of a small amount of residual water after washing on the washing bin cavity 211. When the blanking operation is intended, the magazine cover 220 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 move, so that the screw 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 220 is F1> G1+ G2, and the washing bin cover 220 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 second embodiment, except that the magnetic force applied to the washing bin cover 220 is F1, and not F1+ F2, that is, the magnetic force of F2 is not present, but the relationship between the magnitude of the force applied to the washing bin cover 220 in the blanking stage, the washing stage, the draining stage, and the blanking stage and the magnitude of the force applied to G1+ G2 are the same as the relationship between the magnitude of the force applied to the cooking appliance of the second embodiment, and the operation of the linear driving device 120 and the operation of the rotary driving device 301 are also the same. Taking the blanking stage as an example, for the embodiment that the discharge port 212 is normally open, the force-bearing relationship of the washing bin cover 220 is F1> G1+ G2; for the second embodiment shown, the force relationship of the washing bin cover 220 is F1+ F2> G1+ G2. The magnetic force of the blanking stage of the two embodiments is larger than G1+ G2, namely the size relationship is consistent. The difference is that after the blanking action is completed, the washing bin cover 220 does not need to be reset, that is, the washing bin cover 220 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 220 is kept in the open state.

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 mount may be included inside the wash chamber 211. To which both the washer bin cover 220 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 220 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 220; similarly, the descriptions of forces such as magnetic force, magnetic force, gravity, etc. used herein to describe the washing bin cover 220 can be understood as various descriptions of the forces of the components of the washing bin cover 220 and the follow-up load moving along the straight line, and for the sake of brevity, the washing bin cover 220 is simply replaced, and as an example, the forces of the washing bin cover 220 are understood as the forces of the components of the washing bin cover 220 and the follow-up load moving along the straight line.
