Abstract

This invention discloses a washing chamber assembly and a cooking appliance incorporating the same. The washing chamber assembly includes a washing chamber body, a mounting base, a washing chamber cover, a retaining member, and a retaining mating member. The washing chamber body forms a washing chamber with a discharge port. The mounting base is movable along a straight line relative to the washing chamber body. The washing chamber cover is connected to the mounting base and is movable along a straight line with the mounting base. Both the retaining member and the retaining mating member are magnetic components, and there is a magnetic force between the retaining member and the retaining mating member. In the initial state, the washing chamber cover is held in a closed position by the magnetic force between the retaining member and the retaining mating member.

Description

Technical Field

[0001] This invention relates to the technical field of kitchen appliances, and more specifically to a washing chamber assembly and a cooking appliance having the same. Background Technology

[0002] Existing cooking appliances, such as automatic rice cookers, typically have a separate washing chamber with a discharge port at the bottom and a cover to close the discharge port. An agitator is included for washing. This agitator is located inside the washing chamber, and a drive device, such as a motor, is connected to it via a mechanical connection structure, such as a shaft or connector, to drive its rotation around an axis. To open and close the discharge port, the shaft, connector, or other mechanical connection structure is connected to the washing chamber cover to move the cover up and down and to hold it in the closed position.

[0003] Since the washing hopper cover and the drive unit use a mechanical transmission method, and the mechanical connection structure is located inside the washing hopper, these mechanical connection structures will inevitably come into contact with the washing water, making them dirty and requiring manual cleaning, resulting in a poor user experience.

[0004] Therefore, a washing bin assembly and a cooking appliance having the same are needed to at least partially solve the above problems. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially solve the above problems, the present invention provides a washing chamber assembly for a cooking appliance, comprising:

[0007] The main body of the washing bin forms a washing chamber with a discharge port;

[0008] Mounting base, which is movable in a straight line relative to the main body of the washing hopper;

[0009] A washing hopper cover, which is connected to the mounting base and moves linearly along the mounting base between an open position where the discharge port is open and a closed position where the discharge port is closed;

[0010] Retaining components;

[0011] A retaining fitting member is provided on the mounting base.

[0012] The retaining member and the retaining mating member are both magnetic members, and there is a magnetic force between the retaining member and the retaining mating member. The washing hopper cover is held in the closed position by the magnetic force in the initial state.

[0013] According to this solution, the washing chamber cover can be kept closed by the magnetic force between the retaining member and the retaining mating member. When the washing chamber is not in use, such as when the cooking appliance is not working or when the cooking appliance is cooking, the discharge port can be kept closed, isolating the cooking space from the outside world. This can prevent foreign objects such as dust and insects from entering the inner pot, thus keeping the inner pot clean and uncontaminated when the cooking appliance is not working. When the cooking appliance is cooking, the food in the inner pot is not contaminated and has a good heat preservation effect, which is conducive to improving cooking efficiency.

[0014] Optionally, the magnetic component includes at least one of a magnet, electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel. Thus, the translational mating component and the translational driving component can generate a permanent magnetic field, an electromagnetic field, or be magnetized by a magnetic field.

[0015] Optionally, at least one of the translational mating component and the translational driving component is a magnet. Therefore, neither the translational mating component nor the translational driving component is electrically charged, eliminating the need to consider waterproofing for either during the manufacturing stage.

[0016] Optionally, the translational mating component is a magnet, and the translational driving component is one of a magnet, iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel;

[0017] Alternatively, both the translational mating component and the translational driving component may be magnets;

[0018] Alternatively, the translational mating component may be made of iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel, and the translational driving component may be a magnet.

[0019] Therefore, magnets enable greater magnetic force and stable state between translational mating parts and translational driving parts; the magnetism of iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel is not affected by high temperature, so the high temperature during cooking can be avoided from affecting the magnetism of translational mating parts, thus keeping their performance unchanged.

[0020] Optionally, at least one of the retaining member and the retaining engagement member is an electromagnet. Thus, the energization state of the electromagnet can be controlled to keep the washing hopper cover in the closed position.

[0021] Optionally, the retaining member and the retaining mating member are positioned opposite each other and have opposite magnetic poles. Thus, the washing hopper cover is held in the closed position by magnetic attraction.

[0022] Optionally, the retaining member is disposed in the main body of the washing hopper, or the retaining member is disposed in the main body of the washing hopper by at least one of the following methods: snap-fit, fastener connection, or in-mold injection molding. This results in a simple structure and facilitates manufacturing.

[0023] Optionally, the retaining fitting member is disposed on the mounting base by at least one of the following methods: snap-fit, fastener connection, or in-mold injection molding. Therefore, the method of setting the retaining fitting member is simple and easy to operate.

[0024] Optionally, the washing bin cover can move up and down along a straight line, and the retaining member and the retaining mating member are arranged vertically; thus, the washing bin cover has a good magnetic retention effect.

[0025] Alternatively, the washing hopper cover may block all of the discharge ports, or it may block only a portion of the discharge ports. Thus, the washing hopper cover can be configured, according to design requirements, to either block the discharge ports itself or, together with other connected components, block the discharge ports.

[0026] Optionally, the washing hopper cover is located below the washing hopper body at least in the open position, and the retaining member is located above the retaining engagement member. Thus, the washing hopper cover is held in the closed position by an upward magnetic force.

[0027] Optionally, the weight of the washing hopper cover, the mounting base, and the follower load thereon is G1, the magnetic force between the retaining member and the retaining engagement member is upward and is F2, wherein the follower load includes at least the retaining engagement member, and the force relationship when the washing hopper cover is in the initial state is F2≥G1. Therefore, the washing hopper cover is more stably and reliably positioned in the closed position.

[0028] Optionally, the washing hopper cover and the mounting base can be formed as a single piece or as separate components. This allows for easier manufacturing in the separate component design, while the single-piece design simplifies the assembly process and offers greater design flexibility.

[0029] Optionally, the retaining member and the retaining mating member are located outside the washing chamber. This allows for the provision of a magnetic force from outside the washing chamber to keep the washing chamber cover closed; it also simplifies the internal structure of the washing chamber, increases its volume, improves the single-pass capacity of the washing chamber, and facilitates cleaning of the washing chamber.

[0030] Optionally, the mounting base includes a mounting sleeve portion located radially outside the washing chamber, with seat openings spaced circumferentially at its bottom. The retaining fitting member is located at the top of the mounting sleeve portion. Thus, during material discharge, material can fall through the seat openings; the retaining fitting member can be closer to the retaining member to provide greater magnetic force to keep the washing chamber cover closed.

[0031] Optionally, the mounting base further includes a mounting base portion connected to the mounting base cylinder portion, and the washing bin cover is disposed on the mounting base portion;

[0032] Alternatively, the washing bin is covered at the bottom of the mounting base.

[0033] Optionally, the retaining member and the retaining mating member are located inside the washing chamber. This allows a magnetic force to be provided from inside the washing chamber to keep the washing chamber lid closed; the cooking appliance has a simple external structure, which is beneficial for product miniaturization.

[0034] Optionally, the mounting base is located within the washing chamber. The mounting base includes a mounting base portion and a mounting cylinder portion connected to the mounting base portion. The mounting cylinder portion is movably disposed on the washing chamber body. The washing chamber cover and the retaining fitting member are disposed on the mounting base portion. Therefore, the washing chamber assembly has a simple structure and is easy to manufacture.

[0035] According to another aspect of the invention, a cooking appliance is provided, which includes a washing bin assembly as described in any of the preceding aspects.

[0036] Optionally, the assembly also includes a transmission component, and the washing hopper assembly further includes a translational mating component disposed on the mounting base; the transmission component includes a transmission body and a translational drive component, and the translational drive component is disposed on the transmission body.

[0037] Wherein, both the translational mating component and the translational driving component are magnetic components, and there is a magnetic force between the translational mating component and the translational driving component. When the state of the translational driving component is changed to change the magnetic force between the translational mating component and the translational driving component, the washing hopper cover moves between the open position of opening the discharge port and the closed position of closing the discharge port.

[0038] Therefore, the washing hopper cover can be driven to move linearly by magnetic force. When the state of the translational drive component is changed, the magnitude of the magnetic force is changed, either increasing or decreasing, or the presence or absence of the magnetic force is changed, either from none to present or from present to none. The washing hopper cover can be opened and closed by magnetic force, thereby realizing the opening and closing of the discharge port.

[0039] Optionally, the magnetic force between the translational mating member and the translational driving member is F1, where F1 has a maximum value of F1max, and the magnetic force between the retaining member and the retaining mating member is F2, where F2 has a maximum value of F2max, where F1max > F2max. Thus, the washing hopper cover can be easily opened and closed by magnetic force.

[0040] Optionally, the magnetic poles of the translational mating member and the magnetic poles of the retaining mating member are oriented in the same direction, and the magnetic poles of both are identical. Thus, the retaining member and the retaining mating member can provide an auxiliary force to guide the washing hopper cover toward its closed position, making the closing action easier.

[0041] Optionally, the translational mating component and the retaining mating component can be the same or different magnetic components. This allows for the translational mating component and the retaining mating component to be made from the same or different magnetic materials, providing greater design freedom.

[0042] Optionally, the translational mating parts are spaced P1 times apart, and the retaining mating parts are spaced P2 times apart. The magnetic properties of a single translational mating part are greater than or equal to the magnetic properties of a single retaining mating part, where P1>P2 and P2≥1. Thus, F1max>F2max can be achieved.

[0043] Optionally, the translational mating component and the retaining mating component are the same magnetic component, and the translational mating component and the retaining mating component are formed as a single piece. Thus, a portion of the translational mating component can generate a magnetic force with the retaining component to keep the washing hopper cover closed, facilitating manufacturing and assembly.

[0044] Optionally, the retaining member is solid cylindrical in shape, and the translational mating component has one annular component. The volume of the retaining member is smaller than the volume of the translational mating component. Therefore, F1max > F2max.

[0045] Optionally, the magnetic component includes at least one of a magnet, electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel. Thus, the translational mating component and the translational driving component can generate a permanent magnetic field, an electromagnetic field, or be magnetized by a magnetic field.

[0046] Optionally, at least one of the translational mating component and the translational driving component is a magnet. Therefore, neither the translational mating component nor the translational driving component is electrically charged, eliminating the need to consider waterproofing for either during the manufacturing stage.

[0047] Optionally, the translational mating component is a magnet, and the translational driving component is one of a magnet, iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel;

[0048] Alternatively, both the translational mating component and the translational driving component may be magnets;

[0049] Alternatively, the translational mating component may be made of iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel, and the translational driving component may be a magnet.

[0050] Optionally, the transmission assembly is linearly movable relative to the washing hopper body, wherein when the transmission assembly is moved, the washing hopper cover moves linearly to open and close the discharge port. Thus, the magnitude of the magnetic force between the translational mating member and the translational driving member is controlled by changing the distance between them, thereby causing the washing hopper cover to open and close.

[0051] Optionally, at least one of the translational mating component and the translational driving component is an electromagnet, wherein when the energization state of the electromagnet is changed, the washing hopper cover moves linearly to open and close the discharge port. Thus, the magnitude, interruption, and / or direction of the current can be controlled to change the magnitude and / or presence of the magnetic force, generating magnetic attraction and / or magnetic repulsion to move the washing hopper cover.

[0052] Optionally, the translational drive member and the translational mating member are positioned opposite each other, and their magnetic poles face opposite or the same direction. Therefore, the magnetic force between the translational drive member and the translational mating member can be magnetic attraction and / or magnetic repulsion.

[0053] Optionally, the system also includes a main frame, on which the transmission assembly is mounted. This allows the electrically powered transmission assembly to be located outside the washing hopper assembly, facilitating user cleaning operations on the washing hopper assembly, and eliminating the need to consider waterproofing of the transmission assembly during the manufacturing process of the washing hopper assembly.

[0054] Optionally, the system also includes a pot body and a pot lid, with the pot lid fitting over the pot body. The washing chamber assembly is disposed on the pot lid, and the pot lid is detachably connected to the pot body so that the user can remove the pot lid. Thus, when the user wishes to clean the washing chamber assembly, they only need to remove the pot lid for cleaning, making it convenient for the user.

[0055] Optionally, the system also includes a drain assembly, wherein the main body of the washing hopper has a drain outlet; the drain assembly includes a drain pipe, and the pot lid includes a pot lid body and a detachable cover detachably connected to the pot lid body, with some or all of the drain pipe detachably or non-detachably mounted on the detachable cover. Thus, when the user wishes to clean the drain pipe, they can simply remove the detachable cover for cleaning, making it convenient for the user.

[0056] Optionally, the system also includes a live-line device, which is mounted on the main frame but not on the lid or the pot body. This allows the live-line device to be positioned outside the lid and pot body, facilitating cleaning operations for the lid, washing chamber assembly, and pot body, and eliminates the need to consider waterproofing the live-line device during the manufacturing process of the lid and pot body.

[0057] Optionally, the energized device includes a drive unit, a main board, a heating device, and a display board for driving the transmission assembly portion to rotate and move linearly.

[0058] Optionally, a storage mechanism and a feeding mechanism are included. The pot body is located on the first side of the main frame. The feeding mechanism is used to transport the ingredients in the storage mechanism to the washing chamber. The storage mechanism, the feeding mechanism, and the transmission assembly are all located on the first side of the main frame and above the washing chamber assembly. A clean water tank and a wastewater tank are also included. The clean water tank and the wastewater tank are located on a second side of the main frame, different from the first side. Therefore, the feeding mechanism can be close to the storage mechanism, occupying less space, and can utilize gravity to automatically feed materials into the washing chamber without the need for additional drive devices such as feeding pumps and feeding pipelines, reducing costs. The arrangement of the cooking utensils is more reasonable, reducing the product height and simplifying the structure of the cooking utensils, which is beneficial for product miniaturization.

[0059] The main body of the washing hopper also has a drain outlet, and the washing hopper cover has a connecting position and a closed position. When the washing hopper cover is in the connecting position, the drain outlet is connected to the washing chamber; when the washing hopper cover is in the closed position, the drain outlet is not connected to the washing chamber. Therefore, the washing hopper cover can also be used as a drain valve. When washing, the washing hopper cover is in the closed position; when draining, the washing hopper cover is in the connecting position, allowing wastewater to be discharged through the drain outlet. This design is dual-purpose, simple, convenient, and inexpensive. Furthermore, the above solution eliminates the need for a separate drain valve, thus preventing the washing hopper cover from becoming electrified and affecting the cleaning process.

[0060] The device includes a body assembly, which includes a feeding mechanism for conveying food ingredients to the washing chamber. The feeding mechanism is movably disposed at least between a storage position and a mating position. In the storage position, the feeding mechanism is folded to one side of the body assembly or partially or completely housed inside the body assembly. In the mating position, the feeding mechanism extends or protrudes away from the body assembly.

[0061] The device includes a body assembly, which includes the transmission assembly. The transmission assembly is movably disposed at least between a retracted position and a mating position. In the retracted position, the transmission assembly is folded to one side of the body assembly or partially or completely housed within the body assembly. In the mating position, the transmission assembly extends or protrudes away from the body assembly. (Cooking space)

[0062] This allows for a reduction in the height of the cooking utensils, facilitating product miniaturization. It also allows for space above the lid, making the placement and removal of the pot and lid less restrictive and easier to operate. Furthermore, it prevents contact with the main components, thus avoiding damage to them. Attached Figure Description

[0098] This invention provides a cooking appliance equipped with a washing system. This washing system enables the cooking appliance to perform multiple functions, including fully automatic feeding, water intake, washing, and discharging of ingredients.

[0099] The cooking appliance of the present invention will now be described in detail with reference to the accompanying drawings.

[0100] First Implementation Method

[0101] Figures 1 to 22 A first embodiment of the cooking appliance 1 is shown, with reference to Figure 1 and Figure 2 The cooking appliance 1 includes a body assembly 11 and a pot assembly. The bottom of the body assembly 11 has a base 12, on which the pot assembly can be placed and removed so that the pot assembly can be placed in any desired location, such as a dining table.

[0102] The pot assembly includes a pot body 2, an inner pot 3 disposed within the pot body 2, and a lid 4 fitted onto the pot body 2. The pot body 2 is detachably mounted on a base 12. The inner pot 3 is removably placed within the pot body 2. The lid 4 is detachably attached to the pot body 2. In a preferred embodiment, the lid 4 can be completely removed from the pot body 2, allowing the user to easily remove the entire lid 4 from the pot body 2 for cleaning. When the lid 4 is fitted onto the pot body 2, a cooking space is formed between the lid 4 and the inner pot 3.

[0103] The base 12 typically houses a heating device and a power supply module for supplying power to the heating device. When the pot assembly is placed on the base 12, the power supply module supplies power to the heating device, enabling it to heat the inner pot 3 within the pot body. In a preferred embodiment, the heating device is electromagnetic heating. Exemplarily, the heating device may include a coil and a coil wound on the coil, so that when energized, the heating device can generate heat to heat the inner pot 3. It is understood that in other embodiments not shown, the heating device may also be configured with other structures, such as heating wire heating. Exemplarily, the power supply module may be a plug adapted to an external power source, which supplies power to the heating device when plugged in. The power supply module may also be a battery housed in the base 12, or it may be an electrical connection wire electrically connected to other power supply modules on the body assembly 11.

[0104] refer to Figures 2-9The machine body assembly 11 also includes a storage mechanism and a feeding mechanism 100. The storage mechanism includes a storage bin 13, which can store solid materials such as rice, millet, corn kernels, black beans, red beans, and mung beans. The storage bin 13 has a side outlet, meaning that the outlet is located on the side of the storage bin 13 to facilitate the outflow of materials from the storage bin 13. In the illustrated embodiment, the outlet is located at the bottom of the storage bin 13, further facilitating the outflow of materials from the storage bin 13 by gravity. The top of the storage bin 13 may be covered with a storage bin cover. Materials can be added to the storage bin by opening the storage bin cover.

[0105] Continue to refer to Figures 2-9 as well as Figure 12 The feeding mechanism 100 includes a feeding bin 110. The feeding bin 110 has an inlet 111, an outlet 112 disposed below the inlet 111, and a vertically extending feeding channel disposed between the inlet 111 and the outlet 112. The feeding channel is used to convey solid materials. Both the inlet 111 and the outlet 112 are disposed on the side wall of the feeding bin 110. The feeding bin 110 also has a water inlet 113, an outlet 114 disposed below the water inlet 113, and a vertically extending water channel disposed between the water inlet 113 and the outlet 114. The water inlet 113 is disposed on the side wall of the feeding bin 110, and the outlet 112 is disposed at the bottom of the feeding bin 110. The feeding bin 110 is at least in a first position (e.g., Figure 2 The initial state shown) and the second position (e.g.) Figure 3 The feed hopper 110 is movable between the prepared feeding state shown. When the feed hopper 110 is in the first position, the feed channel and outlet of the feed hopper 110 and the feed inlet 201 of the washing hopper assembly 200 (described below) are not connected.

[0106] like Figure 4 As shown, the feeding hopper 110 also has an additional position. When the feeding hopper is in the additional position, the inlet 111 of the feeding hopper 110 and the outlet of the storage hopper 13 are connected. Solid materials enter the feeding channel of the feeding hopper and are discharged through the outlet 112 into the inlet 201 of the washing hopper assembly 200. The feeding hopper 110 is generally constructed as a columnar structure, and the inlet 111 is an arc-shaped opening extending along the circumferential direction of the feeding hopper 110. The feeding hopper 110 is in a second position (e.g., Figure 3 (as shown in the ready-to-feed state) and additional positions (such as...) Figure 4 It can move between the feeding states shown, and in the second position (e.g.) Figure 3When the material is ready to be unloaded (as shown), the feeding bin 110 is moved downwards, and the outlets of the feeding bin 110 and the storage bin 13 will switch from closed to connected. That is, the inlet 111 of the feeding bin 110 is opened, and at the same time, the outlet 112 of the feeding bin 110 is also opened. Therefore, the material in the storage bin 13 can be fed into the washing bin assembly 200 through the feeding channel of the feeding bin 110.

[0107] Washing bin components

[0108] like Figure 2-9 as well as Figure 13-16 As shown, the cooking appliance 1 also includes a washing chamber assembly 200, which is disposed within the pot lid 4. When the pot lid 4 is removed from the pot body 2, the washing chamber assembly 200 is also removed to facilitate disassembly and cleaning. The washing chamber assembly 200 includes a washing chamber body 210 with a discharge port 212. The washing chamber body 210 has a washing chamber 211, through which washed materials can be discharged. The washing chamber body 210 also has an inlet 201, through which materials in the feeding chamber 110 described above can enter the washing chamber 211. The inlet 201 is located above the discharge port 212. Furthermore, the washing chamber body 210 forms a washing chamber 211 with an inlet 201 and a discharge port 212.

[0109] The washing hopper assembly 200 includes a side wall portion 6. The side wall portion 6 is disposed on the pot lid 4 and forms the washing hopper body 210, surrounding a washing chamber 211 having a discharge port 212. In a preferred embodiment, the side wall portion 6 is formed as part of the pot lid 4, that is, the side wall portion 6 and the pot lid 4 are integrally formed. The side wall portion 6 can be configured to extend vertically, so that the washing chamber 211 is of the same width from top to bottom, or it can be configured to extend obliquely from top to bottom toward the interior of the washing chamber 211, i.e., the washing chamber 211 is wider at the bottom and narrower at the top, to reduce material residue. Furthermore, the inner surface of the side wall portion 6 is configured as a smooth surface to further reduce material residue. The washing hopper assembly 200 also includes an agitator 19 disposed within the washing hopper chamber and a washing hopper cover 270 disposed below the agitator 19. The washing hopper cover 270, together with a portion of the first mounting base 220 (described below), the agitator 19, and the sealing member 261 (described below), covers the discharge port 212.

[0110] In other embodiments, the washing hopper cover 270 can cover the discharge port 212 separately, that is, the discharge port 212 can be completely closed by the washing hopper cover 270 alone.

[0111] The washing hopper cover 270 is movably disposed on the washing hopper body 210. Specifically, the washing hopper cover 270 is movable between an open position where the discharge port 212 is opened and a closed position where the discharge port 212 is closed. Figure 2-6 As shown, the washing hopper cover 270 is located at the top, in the closed position covering the discharge port 212; as Figure 7-9 As shown, the washing chamber cover 270 moves downwards and is in the open position of the discharge port 212. At this time, the material in the washing chamber 211 can fall into the inner pot 3 through the discharge port 212.

[0112] In the illustrated embodiment, the agitator is fixed and supported on the first mounting base. The two ends of the washing hopper cover 270 contact the agitator 19 and the first mounting base 220 respectively, and the axial degrees of freedom at both ends are simultaneously constrained by the agitator 19 and the first mounting base 220. The agitator 19 and the washing hopper cover 270 can move together between an open position and a closed position. The agitator 19 is rotatable relative to the washing hopper cover 270. In other embodiments not shown, the agitator 19 may also be fixedly connected to the washing hopper cover 270, meaning the washing hopper cover 270 and the agitator 19 are rotatable together. That is, when the agitator 19 rotates, the washing hopper cover 270 may or may not rotate.

[0113] In one embodiment, the agitator 19 can rotate during washing and discharging operations. Preferably, the agitator 19 is configured in a turntable shape and has a conical guide surface that is axially inclined and slopes outward from top to bottom along the radial direction of the agitator 19. This design allows the material on the agitator 19 to be more easily discharging during rotation, in addition to the centrifugal force, thanks to the inclined guide surface. Furthermore, the inclined guide surface facilitates downward sliding of the material, reducing residual material in the washing chamber 211.

[0114] Transmission components

[0115] In one embodiment, the cooking appliance 1 further includes a transmission assembly 300, which is movable in a straight line. Specifically, the transmission assembly 300 is engageable with the feeding bin 110 such that the transmission assembly 300 moves with the feeding bin 110 in a first position (e.g., Figure 2 (as shown) and the second position (as shown) Figure 3 The transmission assembly 300 can drive at least a portion of the washing bin assembly 200 to rotate, for example, at least the agitator 19, to complete the washing and / or discharge process; and can drive the agitator 19 together with the washing bin cover 270 to move between the open and closed positions to complete the discharge and drainage process.

[0116] The transmission component 300 is disposed within the storage mechanism or the feeding mechanism 100. Specifically, the transmission component 300 is not disposed on the lid 4. This design, by placing the electrically powered transmission component 300 elsewhere on the lid 4, reduces the number of components on the lid 4, simplifying the lid structure. It also facilitates cleaning operations for the lid 4 and the washing hopper assembly 200. Furthermore, this design eliminates the need to consider waterproofing of the transmission component 300 during the manufacturing stage of the lid 4, thus simplifying the manufacturing process.

[0117] The aforementioned storage mechanism, feeding mechanism 100, transmission assembly 300, and washing bin assembly 200 constitute part of the washing system of this embodiment.

[0118] The transmission structure between the feeding mechanism 100, the transmission assembly 300, and the washing bin assembly 200 is described in detail below with reference to the accompanying drawings.

[0119] The feeding mechanism 100 can be connected to the transmission assembly 300 via contact transmission. The transmission assembly 300 can be connected to the washing chamber assembly 200 via magnetic force generated by a magnetic component, enabling a contactless transmission between the transmission assembly 300 and the washing chamber assembly 200. In this embodiment, the washing chamber cover 270 can be in a closed or open position initially. In other words, when the cooking appliance 1 is not in operation, the discharge port 212 can be in a normally closed or normally open state.

[0120] The illustrated embodiment shows one implementation of the transmission structure between the feeding mechanism 100, the transmission assembly 300, and the washing bin assembly 200. The discharge port 212 is schematically shown to be in a normally closed state.

[0121] As described above, the feeding bin 110 can move linearly between a first position and a second position together with the transmission assembly 300. Figure 4As shown, the feeding bin 110 also has an additional position. In the additional position, the feeding bin 110 is closer to the washing chamber 211. The feeding bin 110 has a feed channel for conveying solid materials, which is not in communication with either the storage bin 13 or the washing chamber 211 in the first and second positions. When the feeding bin 110 moves to the additional position, the transmission assembly 300 does not move accordingly. Thus, in the additional position, the feeding bin 110 can extend relative to the transmission assembly 300 and into the washing chamber 211, at which time the feed channel of the feeding bin 110 can communicate with both the storage bin 13 and the washing chamber 211. In this embodiment, the feeding bin 110 has a two-stage movement relative to the transmission assembly 300. In one stage of movement, i.e., when moving from the first position to the second position and when returning from the second position to the first position, the feeding bin 110 moves together with the transmission assembly 300. In the other stage of movement, i.e., when moving from the second position to the additional position and when moving from the additional position to the second position, the feeding bin 110 moves separately from the transmission assembly 300. The feeding bin 110 can move from the second position to the additional position and from the additional position to the second position, allowing the feeding bin 110 to enter or leave the washing chamber 211, facilitating material feeding and stopping.

[0122] The washing hopper assembly 200 is located below the transmission assembly 300. When the feeding hopper 110 is in the additional position, the transmission assembly 300 can abut against the top surface of the washing hopper body 210, so that the transmission assembly 300 can stop moving when the feeding hopper 110 moves from the second position to the additional position. In other embodiments not shown, a separate fixed support frame is included, which abuts the transmission assembly 300 when the feeding hopper 110 is in the additional position. This fixed support frame can be a separate support frame directly fixed to the pot lid 4.

[0123] like Figures 10 to 12 As shown, the feeding mechanism 100 may further include a linkage 130. The linkage 130 is disposed at the bottom of the feeding bin 110. For example, a rotary connection structure 117 is provided on the bottom surface of the feeding bin 110, and the linkage 130 is provided with a structure that cooperates with the rotary connection structure 117. Rotating the linkage 130 connects it to the rotary connection structure 117. The linkage 130 is then fixed to the rotary connection structure 117 with screws. The transmission body 310 is provided with a central hole 313, which is located at the center of the transmission body 310. The feeding bin 110 is located within the central hole 313.

[0124] The linkage 130 is located on the lower side of the transmission body 310 and has an upward-facing linkage support surface 131 for supporting the transmission assembly 300 upwards. With the aid of the linkage support surface 131, the feeding bin 110 can drive the transmission assembly 300 to move upwards. In the illustrated embodiment, the transmission assembly 300 can move downwards along with the feeding bin 110 due to its own weight. The linkage support surface 131 can be constructed as an inclined surface in the vertical direction. The illustrated embodiment shows the linkage support surface 131 as an annular conical surface, specifically inclined outwards from top to bottom along the radial direction of the linkage 130. This guides the feeding bin 110 and the transmission assembly 300 as they move from a separated state to a connected state, resulting in better cooperation.

[0125] The feeding mechanism 100 also includes a linear drive device 120. The linear drive device 120 is connected to the feeding bin 110 and drives the feeding bin 110 to move linearly. Specifically, the feeding bin 110 is provided with a vertically extending screw hole 115, and the feeding mechanism 100 also includes a screw 121. The screw 121 is connected to the output shaft of the linear drive device 120 and is located within the screw hole 115. When the output shaft rotates, the screw 121 can move relative to the feeding bin 110 within the screw hole 115, thereby causing the feeding bin 110 to move up and down.

[0126] The feeding mechanism 100 also includes a fixed bracket 122, a fixed seat 123, and a fixed pressure plate 124. The fixed bracket 122 is located within the storage bin 13 and can be connected to the storage bin 13. For example, the inner bottom surface of the storage bin 13 may be provided with upwardly extending studs (not shown), and the fixed bracket 122 may be provided with screw bases 126 with through holes at intervals, through which screws can pass and be locked to the studs, thereby allowing the fixed bracket 122 to be installed into the storage bin 13. The fixed bracket 122 may be provided with a downward-opening receiving cavity, and a linear drive device 120 is connected to the fixed bracket 122 and located within the receiving cavity. Specifically, the linear drive device 120 is located within a recess in the fixed seat 123, which is accommodated within the receiving cavity. The recess is adapted to the shape of the linear drive device 120 to limit the rotation and vertical movement of the linear drive device 120. The fixed pressure plate 124 is located on the lower side of the linear drive device 120 opposite to the fixed base 123. The fixed pressure plate 124 can be connected to the fixed base 123. For example, both the fixed pressure plate 124 and the fixed base 123 are provided with screw holes, and the fixed bracket 122 is provided with a downwardly extending screw post 127. The screw passes through the screw holes of the fixed pressure plate 124 and the fixed base 123 and is locked to the screw post 127. The end of the screw 121 is clamped between the fixed pressure plate 124 and the fixed base 123.

[0127] An outlet for the storage hopper 13 can be formed between the bottom of the fixed bracket 122 and the inner bottom surface of the storage hopper 13. This outlet is located on one side of the fixed bracket 122. An outlet seal 125 is provided on the side of the fixed bracket 122 corresponding to this outlet. The outlet seal 125 can abut against the side wall of the feeding hopper 110 to prevent material from entering the feeding mechanism 100. The fixed bracket 122 is also provided with vertically extending guide posts 128 at intervals. Guide protrusions 116 are provided at intervals on the top of the feeding hopper 110, protruding from the side wall of the feeding hopper 110. The guide protrusions 116 are located between the spaced guide posts 128 and are movable along the guide posts 128 to prevent the feeding hopper 110 from shifting during movement.

[0128] The washing hopper assembly 200 also includes a washing hopper mating part 230 and a mounting base 240. The washing hopper mating part 230 can be connected to the mounting base 240. Part or all of the mounting base 240 can be movably disposed in a straight line on the washing hopper body 210. In the illustrated embodiment, part of the mounting base 240 is movable in a straight line. The agitator 19 is located in the washing chamber 211 and connected to the mounting base 240. The agitator 19 is rotatable with the mounting base 240 relative to the washing hopper body 210 about a first rotation axis Ax1. The washing hopper cover 270 can be disposed on the mounting base 240 and is movable in a straight line with the mounting base 240. The mounting base 240 is rotatable with respect to the washing hopper body 210 about the first rotation axis Ax1. The transmission assembly 300 includes a transmission body 310 and a washing hopper drive 320. The transmission body 310 is rotatable with respect to the washing hopper body 210 about a second rotation axis Ax2. The transmission body 310 is engageable with and rotatable relative to the feeding bin 110. The washing bin drive 320 is disposed on the transmission body 310 and can be installed to the transmission body 310, for example, by means of screw connection.

[0129] There may be a magnetic force between the washing hopper mating part 230 and the washing hopper drive part 320. When the transmission body rotates, the mounting base 240 and the stirring part 19 thereon rotate under the action of the magnetic force; and when the magnetic force between the washing hopper mating part 230 and the washing hopper drive part 320 is changed, the mounting base 240 moves in a straight line to open and close the washing hopper cover 270.

[0130] The transmission body 310 has a non-drive position that disengages the washing bin mating part 230 from the washing bin drive part 320 (e.g., Figure 6 and Figure 7 (The different material feeding states shown) and the driving positions that link the washing bin mating part 230 and the washing bin drive part 320. The driving positions include a first driving position (e.g., Figures 3 to 5 The states shown) and the second drive position (as shown) Figure 8The material feeding state is shown. The first drive position corresponds to the closed position, the second drive position corresponds to the open position, and the non-drive position can be the open position (e.g., ...). Figure 6 and Figure 7 The different material feeding states shown can also be in the closed position (e.g., ...). Figure 2 (The initial position), of course, in other embodiments, the initial position can be set to the open position.

[0131] The first position can be a non-driven position, which includes an initial position and an intermediate position (e.g., ...). Figure 6 and Figure 7 (Different material dropping states are shown); the second position can be a driving position and includes both the first and second driving positions. Further, when the transmission body 310 is in the first position, the washing bin driving component 320 is disengaged from the washing bin mating component 230. When the transmission body 310 is in the second position, the washing bin driving component 320 is engaged with the washing bin mating component 230. The intermediate position is located between the initial position and the second driving position. It should be noted that, for ease of understanding, Figure 6 and Figure 9 The transition state during the operation is shown, and the mounting base 240 of the washing hopper cover 270 is subjected to unbalanced forces in this transition state.

[0132] The washing chamber assembly 200 and the transmission assembly 300 form a contactless transmission system. When washing materials in the washing chamber 211, the washing water exists in a space isolated from the transmission assembly 300 and does not come into contact with it. This prevents the washing water from soiling the transmission assembly 300. Compared to mechanical transmission methods, the contactless transmission method eliminates the need for cleaning the transmission structure, thus improving the user experience.

[0133] In this embodiment, the feeding bin 110 and the transmission assembly 300 can move synchronously, and the transmission assembly 300 and the washing bin cover 270 can move in coordination. This allows only one drive device to move the feeding bin 110, which is sufficient to complete the three linear movements of the feeding bin 110, the transmission assembly 300, and the washing bin cover 270, thus realizing the movement of the feeding bin 110 and the opening and closing of the discharge port 212. Furthermore, only one drive device to rotate the transmission body 310 is needed to realize the throwing action during washing and unloading.

[0134] The washing hopper mating component 230 may include a translational mating component 231. The translational mating component 231 is disposed on the mounting base 240. The washing hopper drive component 320 may include a translational drive component 321. The translational drive component is disposed on the transmission body 310. Both the translational drive component 321 and the translational mating component 231 are magnetic components, and a magnetic force may exist between them. When the state of the translational drive component 321 is changed to change the magnetic force between the translational mating component 231 and the translational drive component 321, the washing hopper cover 270 moves between the open position of opening the discharge port 212 and the closed position of closing the discharge port 212. The transmission assembly 300 and the washing hopper cover 270 can achieve mating movement through magnetic force. When the transmission body 310 is moved, the washing hopper cover 270 can be opened and / or closed by magnetic force, thereby realizing the opening and closing action of the discharge port 212.

[0135] In one embodiment, when the state of the translational drive member 321 is changed, the washing hopper cover 270 moves from the open position to the closed position. Thus, the washing hopper cover 270 can be closed by means of the magnetic force between the translational mating member 231 and the translational drive member 321. In another embodiment, when the state of the translational drive member 321 is changed, the washing hopper cover 270 moves from the closed position to the open position. Thus, the washing hopper cover 270 can be opened by means of the magnetic force between the translational mating member 231 and the translational drive member 321. In the illustrated embodiment, when the state of the translational drive member 321 is changed, the washing hopper cover 270 moves from the open position to the closed position and from the closed position to the open position. Thus, the washing hopper cover 270 can be opened and closed simultaneously by means of the magnetic force between the translational mating member 231 and the translational drive member 321.

[0136] The washing hopper assembly 230 may include a rotating assembly 232. The washing hopper drive assembly 320 may include a rotating drive assembly 322. The rotating assembly 232 is mounted on the mounting base 240. The rotating drive assembly is mounted on the transmission body 310, and both the rotating drive assembly and the rotating assembly 232 are magnets. When the transmission body 310 rotates, the agitator 19 rotates under the magnetic force between the rotating drive assembly and the rotating assembly 232. Thus, when the transmission body 310 is rotated while the washing hopper cover 270 is being opened and closed, the washing and discharging actions can be achieved.

[0137] The magnetic component may include at least one of a magnet, an electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel. Optionally, the magnet may be a permanent magnet. Optionally, at least one of the translational mating component 231 and the translational driving component 321 may be a magnet. For example, the translational mating component 231 may be a magnet; the translational driving component 321 may be one of a magnet, an electromagnet, iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel. One example is that both the translational mating component 231 and the translational driving component 321 are magnets, thereby allowing a large magnetic force to exist between the translational mating component 231 and the translational driving component 321 and maintaining a stable state. Another example is that the translational mating component 231 is made of iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel, and the translational driving component 321 is a magnet. Since the magnetism of iron, nickel, cobalt, ferritic steel, martensitic steel, and austenitic-ferritic dual-phase steel is not affected by high temperatures, the high temperatures during cooking can be avoided from affecting the magnetism of the translational mating component 231, thus maintaining its performance. Optionally, at least one of the translational mating component 231 and the translational driving component 321 is an electromagnet.

[0138] When the washing hopper cover 270 and the agitator 19 are both mounted on the same mounting base 240, considering that rotating the mounting base 240 would cause the wires to become tangled, the translational mating component 231 and the translational drive component 321 are not selected as electromagnets. When the washing hopper cover 270 and the agitator 19 are mounted on different mounting bases 240, the opening and closing of the washing hopper cover 270 and the rotation of the agitator 19 are independent of each other, and the translational mating component 231 and the translational drive component 321 can be selected as electromagnets.

[0139] In embodiments excluding electromagnets, the transmission assembly 300 is linearly movable relative to the washing hopper body 210. When the transmission assembly 300 moves to change the magnetic force between the translational mating member 231 and the translational drive member 321, the washing hopper cover 270 moves between an open position with the discharge port 212 open and a closed position with the discharge port 212 closed. In the illustrated embodiment, the direction of movement of the washing hopper cover 270 is controlled by controlling the vertical movement of the transmission assembly 300, based on the change in the direction of the resultant force of the magnetic force and gravity, thus moving it to the open and closed positions.

[0140] In the implementation of the electromagnet, when the energization state of the electromagnet is changed, the washing bin cover 270 can move in a straight line to open and close the discharge port 212.

[0141] According to design requirements, the rotary drive member 322 can be located radially outside the rotary mating member 232 in the drive position. Alternatively, the rotary drive member 322 can be located radially inside the rotary mating member 232 in the drive position. Alternatively, the rotary drive member 322 can be located above the rotary mating member 232 in the drive position.

[0142] The washing hopper assembly 200 is located below the transmission assembly 300. The feeding hopper 110, the washing hopper cover 270, and the transmission assembly 300 can all move vertically. The translational drive member 321 and the translational mating member 231 are vertically aligned, and their magnetic poles are either opposite or the same. When the magnetic poles are opposite, the magnetic force between the translational drive member 321 and the translational mating member 231 is a magnetic attraction force, which moves the washing hopper cover 270. When the magnetic poles are the same, the magnetic force between the translational drive member 321 and the translational mating member 231 is a magnetic repulsion force, which moves the washing hopper cover 270. In the illustrated embodiment, the translational drive member 321 and the translational mating member 231 have opposite magnetic poles, and the magnetic force between them is a magnetic attraction force.

[0143] like Figure 10 As shown, the transmission body 310 is configured 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, a translational drive member 321 is disposed on the transmission top wall 311, and a rotational drive member 322 is disposed on the transmission side wall 312. The translational drive member 321 is disposed on the transmission body 310 by at least one of snap-fit, fastener connection, or in-mold injection molding. In the illustrated embodiment, the translational drive member 321 is detachably mounted to the transmission body 310 by fasteners such as screws.

[0144] The height of the transmission body 310 in the first driving position is lower than its height in the second driving position. More specifically, the first driving position is above the second driving position. When the transmission body 310 is in the first driving position, the translational drive member 321 and the translational mating member 231 can be linked, and the rotary drive member 322 and the rotary mating member 232 can be linked. When the transmission body 310 is in the second driving position, the translational drive member 321 and the translational mating member 231 are disengaged, and the rotary drive member 322 and the rotary mating member 232 are linked. For the illustrated embodiment, see [reference needed]. Figure 8 When the transmission body 310 is in the second driving position, the magnetic force between the translational drive component 321 and the translational mating component 231 is less than the weight of the washing hopper cover 270 and the first mounting base 220 and the agitator 19 connected thereto. As a result, the washing hopper cover 270 can be kept in the open position.

[0145] In this embodiment, the washing chamber fitting 230 can be located outside the washing chamber 211, that is, the rotary fitting 232 and the translational fitting 231 are located outside the washing chamber 211. When the transmission body 310 is in the first driving position and the second driving position, the rotary drive 322 is located radially outside the rotary fitting 232.

[0146] The following is for reference. Figures 13 to 17 The structure of the washing bin assembly 200 according to the first embodiment is described.

[0147] like Figure 13 and Figure 14 As shown, the mounting base 240 includes a first mounting base 220 and a second mounting base 250 connected to the first mounting base 220. The first mounting base 220 is located radially inside the second mounting base 250 and is linearly movable relative to the second mounting base 250. The agitator 19, the washing hopper cover 270, and the translational fitting 231 can be disposed on the first mounting base 220. The rotational fitting 232 can be disposed on the second mounting base 250. The first mounting base 220 can rotate with the second mounting base 250.

[0148] The first mounting base 220 may include a mounting base 221 and a mounting cylinder 222 connected to the mounting base 221. The agitator 19 and the washing chamber cover 270 are located on the mounting base 221. The mounting cylinder 222 is located radially outside the washing chamber 211, and its bottom is provided with circumferentially spaced seat openings 224 so that material falls into the inner pot 3 through these openings during material discharge. A translational mating member 231 is provided on the top of the mounting cylinder 222 so that a small distance exists between the translational mating member 231 and the translational drive member 321, generating a sufficiently large magnetic force to move the washing chamber cover 270 up and down.

[0149] The translational mating part 231 is disposed on the mounting base 240 by at least one of the following methods: snap-fit, fastener connection, or in-mold injection molding. For example... Figure 13 As shown, the translational mating component 231 can be pre-embedded in the mounting base 222, for example, by in-mold injection molding. Alternatively, in embodiments not shown, the translational mating component 231 can also be detachably mounted to the mounting base 222 using fasteners such as screws. Specifically, the top surface of the mounting base 222 is provided with a downwardly recessed mounting groove, in which the translational mating component 231 is fixed. Multiple translational mating components 231 can be provided, and they can be block-shaped members, or a single component can be provided, and it can be an annular member, etc. In embodiments with multiple translational mating components 231, the multiple translational mating components 231 can be arranged at intervals along the circumference of the first mounting base 220, preferably arranged in a ring array.

[0150] The washing hopper assembly 200 also includes a hopper body base 217. The hopper body base 217 is located below the washing hopper body 210 and is detachably connected to the washing hopper body 210 by means such as a fastening connection. A second mounting base 250 is supported on the hopper body base 217 located below it. A rotating mating member 232 can be disposed on the vertically extending outer peripheral surface of the second mounting base 250 so that a small radial distance exists between the rotating mating member 232 and the rotating drive member 322, generating a sufficiently large magnetic force to rotate the mounting base 240. Multiple rotating drive members 322 and rotating mating members 232 can be provided and are block-shaped components. Multiple rotating drive members 322 are arranged circumferentially spaced along the transmission body 310. Multiple rotating mating members 232 are arranged circumferentially spaced along the second mounting base 250.

[0151] When the transmission assembly 300 is in the driving position, the projections of the rotary drive member 322 and the rotary mating member 232 on the plane parallel to the axial direction overlap. When the transmission assembly 300 is in the first driving position, the projections of the rotary drive member 322 and the rotary mating member 232 on the plane parallel to the axial direction have a first overlapping area. When the transmission assembly 300 is in the second driving position, the projections of the rotary drive member 322 and the rotary mating member 232 on the plane parallel to the axial direction have a second overlapping area. The first overlapping area can be larger than the second overlapping area. Multiple rotary drive members 322 and multiple rotary mating members 232 can be arranged in one or two rows axially. For example, in the illustrated embodiment, as shown... Figure 10 and Figure 14 As shown, the rotary drive component 322 and the rotary mating component 232 can both be arranged in a row along the axial direction, and both can be constructed into long strips, i.e., long strip-shaped components. The rotary drive component 322 is placed horizontally, and the rotary mating component 232 is placed vertically.

[0152] The main body 210 of the washing silo may also include a top wall 216, an inner side wall 214 and an outer side wall 215 connected to the top wall 216. Figure 15These three components constitute the aforementioned sidewall portion 6. The inner sidewall 214 is located radially inside the outer sidewall 215 and is radially spaced from it. The inner sidewall 214 encloses the washing chamber 211. The second mounting seat 250 and the mounting sleeve portion 222 are located between the inner sidewall 214 and the outer sidewall 215. One of the first mounting seat 220 and the second mounting seat 250 may be provided with a seat guide groove 223, which extends axially. The other of the first mounting seat 220 and the second mounting seat 250 may be provided with a seat guide portion 251, which is located within the seat guide groove 223 and is linearly movable relative to the seat guide groove 223. By providing a convex-concave guide structure in the first mounting seat 220 and the second mounting seat 250, the first mounting seat 220 can rotate together with the second mounting seat 250, and the first mounting seat 220 can maintain linear movement, preventing displacement.

[0153] The washing bin assembly also includes a support component. The support component is located on the washing bin body 210. The support component has an upward-facing seat limiting surface 252 for supporting the mounting base 240 upwards. In this embodiment, the support component includes a second mounting base 250 and a bin body base 217. The second mounting base 250 has an upward-facing seat limiting surface 252 for supporting the first mounting base 220 upwards. The bin body base 217 supports the first mounting base 220 upwards. Figure 16 The image shows a mounting base 222 with a seat guide groove 223 and a second mounting base 250 with a seat guide portion 251. The top surface of the seat guide portion 251 is a seat limiting surface 252. In an embodiment not shown, the second mounting base 250 has a seat guide groove 223, and the mounting base 222 has a seat guide portion 251. The bottom surface of the seat guide groove 223 is a seat limiting surface 252.

[0154] Optionally, the mounting sleeve portion 222 may include an upper sleeve portion and a lower sleeve portion. The upper sleeve portion protrudes radially outward from the lower sleeve portion, that is, the thickness of the upper sleeve portion is greater than the thickness of the lower sleeve portion. The seat guide groove 223 may be provided in the upper sleeve portion, and the seat opening 224 may be provided in the lower sleeve portion.

[0155] like Figure 13 , Figure 17 and Figure 17AAs shown, to prevent water leakage during the washing process, the washing hopper assembly 200 also includes a discharge port seal 261. The discharge port seal 261 is disposed on the outer periphery of the washing hopper cover 270 so that it moves up and down with the washing hopper cover 270. When the washing hopper cover 270 is in the closed position, the discharge port seal 261 abuts against the washing hopper body 210 at the discharge port 212. Thus, the washing hopper cover 270 is under pressure and does not rotate relative to the first mounting base 220 and the agitator 19. When the washing hopper cover 270 is in the closed position, the discharge port seal 261 seals the gap between the washing hopper cover 270 and the washing hopper body 210, preventing washing water from leaking out of this gap during washing. When the washing hopper cover 270 is in the closed position and the agitator 19 rotates, the washing hopper cover 270 remains stationary relative to the washing hopper body 210, that is, its relative position to the washing hopper body 210 remains unchanged, and it does not rotate with the agitator 19. This ensures a better sealing effect for the material outlet seal 261 and a tighter fit for the washing hopper cover 270, preventing water leakage.

[0156] The washing chamber cover 270 is disposed on the side of the mounting base 221 facing the washing chamber 211, specifically on the upper side of the mounting base 221. The mounting base 221 is rotatable relative to the washing chamber cover 270. The outer periphery of the washing chamber cover 270 may be provided with a radially inwardly recessed cover groove 273. The cover groove 273 is annular. A portion of the inlet seal 261 may be located within the cover groove 273.

[0157] In one embodiment, as illustrated, the inlet seal 261 may be located below the washing hopper body 210. The washing hopper cover 270 may have a cover support surface 271. The cover support surface 271 faces the side where the discharge port 212 is located, specifically facing upwards. The inlet seal 261 may abut against the cover support surface 271 to provide upward support force to the inlet seal 261. When the washing hopper cover 270 is in the closed position, the inlet seal 261 is sandwiched between the bottom of the washing hopper body 210 and the cover support surface 271, and the washing hopper cover 270 is subjected to downward pressure at the cover support surface 271 and remains stationary relative to the washing hopper body 210. In this embodiment, the bottom surface of the side wall portion 6 may abut against the inlet seal 261, specifically the bottom surface of the inner side wall 214 may abut against the inlet seal 261. The inlet seal 261 is subjected to downward compressive force. In other embodiments not shown, the inner surface of the sidewall portion 6 may abut against the inlet seal 261, and the friction between the inlet seal 261 and the sidewall portion 6 may restrict the rotation of the washing hopper cover 270.

[0158] like Figure 17AAs shown, the bottom of the washing hopper body 210 is provided with a main arc-shaped surface 218, which can abut against the material outlet seal 261. The increased contact area between the bottom of the washing hopper body 210 and the material outlet seal 261 facilitates a more stable abutment and a better sealing effect.

[0159] The inlet seal 261 is an annular component and is fitted onto the outer periphery of the washing hopper cover 270. The outer periphery of the washing hopper cover 270 may be provided with a radially outwardly protruding cover boss 272. The inlet seal 261 is disposed on the cover boss 272. The upper surface of the cover boss 272 is a cover support surface 271, which can support the washing hopper cover 270.

[0160] The mounting base 221 may be provided with a cover mounting portion 263, and the washing hopper 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 hole wall of the cover mounting hole 264 to seal the gap between the mounting base 221 and the washing hopper cover 270. The cover mounting portion 263 is provided with a radially recessed mounting groove 265, and the mounting seal 262 is located within the mounting groove 265. An abutment boss is provided within the cover mounting hole 264, and the abutment boss is provided with a seat arc-shaped surface 274 facing the mounting groove 265 to increase the contact area between the mounting seal 262 and the cover mounting hole 264 and improve the sealing effect.

[0161] The agitator 19 can be located on the side of the washing hopper cover 270 opposite to the mounting base 221, specifically on the upper side. That is, the washing hopper cover 270 is located between the agitator 19 and the mounting base 221. The agitator 19 is connected to the cover mounting portion 263. One of the agitator 19 and the cover mounting portion 263 may be provided with a connecting protrusion, and the other may be provided with a connecting groove, with the connecting protrusion located within the connecting groove. Fasteners such as screws can pass through the mounting base 221 and be connected to the connecting protrusion to connect the agitator 19 to the mounting base 221. The figure schematically shows the agitator 19 provided with a connecting protrusion and the cover mounting portion 263 provided with a connecting groove.

[0162] In the embodiment shown, the washing hopper cover 270, mounting base 221, agitator 19, and inlet seal 261 are assembled together. When the washing hopper cover 270 is in the closed position, the washing hopper cover 270, mounting base 221, agitator 19, and inlet seal 261 together block the discharge port 212. When the agitator 19 and mounting base 221 rotate together, the washing hopper cover 270 and inlet seal 261 do not rotate, that is, their relative positions with the washing hopper body 210 remain unchanged. This ensures a better sealing effect of the inlet seal 261 and a tighter fit of the washing hopper cover 270, preventing water leakage.

[0163] Alternatively, the discharge port 212 can be sealed in other ways, such as by sealing the discharge port 212 separately with the washing hopper cover 270, or by sealing the discharge port 212 together with one or more of the seal, agitator 19, and mounting base. One or more of the seal, agitator 19, and mounting base can move synchronously with the washing hopper cover 270, i.e., move together to open and close the discharge port 212 together. Alternatively, one or more of the seal, agitator 19, and mounting base can move separately from the washing hopper cover 270 to open and close the discharge port 212.

[0164] Optionally, the discharge port 212 can be blocked solely by the washing hopper cover 270, which is sufficient to cover the discharge port 212. Furthermore, a sealing element can be provided between the washing hopper cover 270 and the washing hopper body, so that the discharge port 212 is blocked together by the washing hopper cover 270 and the sealing element. The sealing element can be located on the washing hopper cover 270 or on the washing hopper body.

[0165] Optionally, the discharge port 212 is sealed together by the washing hopper cover 270 and a portion of the mounting base. Further, a sealing element may be included, with the washing hopper cover 270, the portion of the mounting base, and the sealing element sealing the discharge port 212 together. The sealing element may be provided on one or more of the washing hopper cover 270, the portion of the mounting base, and the washing hopper body to better seal the discharge port 212. It is understood that this method of sealing the discharge port 212 involves opening and closing a portion of the discharge port 212 via the washing hopper cover 270, and also involves the washing hopper cover 270 moving between an open position (open discharge port 212) and a closed position (closed discharge port 212). Optionally, the washing hopper cover 270 may also be integrally formed with the mounting base.

[0166] Optionally, the discharge port 212 is sealed together by the washing hopper cover 270 and the agitator 19. Further, a sealing element is also included. The washing hopper cover 270, the agitator 19 and the sealing element seal the discharge port 212 together. The sealing element can be provided on one or more of the washing hopper cover 270, the agitator 19 and the washing hopper body to better seal the discharge port 212.

[0167] Optionally, the washing hopper cover 270, the mixing component 19, and the mounting base are formed as a single piece.

[0168] Optionally, the discharge port 212 is sealed together by the washing hopper cover 270, the agitator 19, and the mounting base. Further, a sealing element is also included. The washing hopper cover 270, the agitator 19, the mounting base, and the sealing element seal the discharge port 212 together. The sealing element can be located on one or more of the washing hopper cover 270, the agitator 19, the mounting base, and the main body of the washing hopper. It is understood that the above sealing method of the discharge port 212 involves opening and closing part of the discharge port 212 by the washing hopper cover 270, and also involves the washing hopper cover 270 moving between an open position and a closed position of the discharge port 212, and also involves the washing hopper cover 270 opening and closing the discharge port 212.

[0169] like Figure 13 and Figure 17B As shown, the washing hopper cover 270 can be held in the closed position by magnetic connection in the initial state. Specifically, the washing hopper assembly 200 may also include a retaining member 237 and a retaining mating member 238. The retaining member 237 can be disposed on the washing hopper body 210. In other embodiments not shown, the retaining member 237 may be disposed on a mounting support frame. The mounting support frame is connected to the pot lid 4. This mounting support frame may be a separate support frame directly fixed to the pot lid 4. Both the retaining member 237 and the retaining mating member 238 are magnetic members. At least one of the retaining member 237 and the retaining mating member 238 is a magnet or electromagnet. For example, the retaining member 237 is a magnet, and the retaining mating member 238 is at least one of a magnet, iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel; the retaining member 237 is at least one of iron, nickel, cobalt, ferritic steel, martensitic steel, or austenitic-ferritic dual-phase steel, and the retaining mating member 238 is a magnet. Under the magnetic force between the retaining member 237 and the retaining fitting member 238, the washing chamber cover 270 is initially held in the closed position. Thus, the washing chamber cover 270 can be kept closed due to the magnetic force between the retaining member 237 and the retaining fitting member 238. When the washing chamber 211 is not in use, for example, when the cooking appliance 1 is not working or when the cooking appliance 1 is cooking, the discharge port 212 can remain closed, isolating the cooking space, such as the space of the inner pot 3, from the outside world. This can prevent foreign objects such as dust and insects from entering the inner pot 3, thereby keeping the inner pot 3 clean and uncontaminated when the cooking appliance 1 is not working. When the cooking appliance 1 is cooking, the food in the inner pot 3 is not contaminated and has good heat retention, which is beneficial to improving cooking efficiency.

[0170] The retaining member 237 and the retaining mating member 238 are arranged vertically and opposite to each other in magnetic polarity, so that the magnetic force between them is a magnetic attraction. The washing hopper cover 270 is held in the closed position by the magnetic attraction between the retaining member 237 and the retaining mating member 238. For the illustrated embodiment, as Figure 17BAs shown, the retaining member 237 is located above the retaining fitting member 238. The retaining member 237 can be pre-embedded in the washing hopper body 210, for example, by in-mold injection molding. Alternatively, in embodiments not shown, the retaining member 237 can also be detachably installed in the washing hopper body 210 by snap-fit, fastener connection such as screws, etc. The retaining member 237 can be provided on the top wall 216 of the hopper body.

[0171] The magnetic poles of the translational mating member 231 and the retaining mating member 238 are oriented in the same direction, and the magnetic poles of both are the same. Thus, the retaining member 237 and the retaining mating member 238 can provide an auxiliary force to guide the washing hopper cover 270 toward its closed position, making the closing action easier.

[0172] The weight of the washing hopper cover 270, the mounting base, and the follower load on it is G1. The magnetic force between the retaining member 237 and the retaining mating member 238 is upward and is F2, wherein the follower load includes at least the retaining mating member 238. When the washing hopper cover 270 is in its initial state, the force relationship is F2≥G1. The retaining member 237 and the retaining mating member 238 can be located outside the washing chamber 211. The retaining mating member 238 is located on the top of the mounting base cylinder portion 222. The magnetic force between the translational mating member 231 and the translational drive member is F1, with F1 having a maximum value of F1max. The magnetic force between the retaining member 237 and the retaining mating member 238 is F2, with F2 having a maximum value of F2max, wherein F1max>F2max. This allows the washing hopper cover 270 to be easily opened and closed by magnetic force. Optionally, P1 translational mating parts 231 are spaced apart, and P2 retaining mating parts 238 are provided. The magnetic properties of a single translational mating part 231 are greater than or equal to the magnetic properties of a single retaining mating part 238, where P1>P2 and P2≥1. Optionally, the retaining part 237 is solid cylindrical, and one of the translational mating parts 231 is an annular member. The volume of the retaining part 237 is smaller than the volume of the translational mating part 231. The translational mating parts 231 and the retaining mating parts 238 are the same or different magnetic components. Thus, the translational mating parts 231 and the retaining mating parts 238 can be made from the same or different magnetic materials, allowing for greater design freedom. In the illustrated embodiment, the translational mating parts 231 and the retaining mating parts 238 are the same magnetic components; the retaining mating parts 238 and the translational mating parts 231 are formed as a single piece. Thus, a portion of the translational mating part 231 can generate a magnetic force with the retaining part 237 to keep the washing hopper cover closed, facilitating manufacturing and assembly. In an embodiment not shown, the retaining mating member 238 and the translational mating member 231 are separate components.

[0173] Optionally, such as Figure 17CAs shown, the upper end face of the translational mating part 231 can have an included angle α with the side end face of the rotary mating part 232, where 30°≤α≤150°, for example, α is 30°, 50°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 150°, etc. Preferably, 85°≤α≤95°. Thus, the magnetic fields generated by the translational mating part 231 and the rotary mating part 232 are independent and do not interfere with each other as much as possible. When the transmission body 310 is in the driving position, there is a first magnetic force between the translational driving member 321 and the translational mating member 231, and a second magnetic force between the rotary driving member 322 and the rotary mating member 232. The first and second magnetic forces are at an angle β, where 30°≤β≤150°. For example, β can be 30°, 50°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, or 150°. Preferably, 85°≤β≤95°. Figure 17C The diagram schematically shows that the translational mating member 231 is subjected to a first magnetic force Fa from the translational drive member 321, and the rotary mating member 232 is subjected to a second magnetic force Fb from the rotary drive member 322, with an included angle β between Fa and Fb.

[0174] like Figures 18 to 20 As shown, the transmission assembly 300 may further include a transmission support 330, a mounting bracket 340, and a rotary drive device 301. The transmission support 330 can be located within the central hole 313 of the main body and connected to the transmission main body 310. The transmission main body 310 can be rotatable relative to the transmission support 330. The mounting bracket 340 is located above the transmission main body 310 and can be connected to the transmission support 330, for example, by fasteners such as screws. The rotary drive device 301 can be disposed on the mounting bracket 340, and its output shaft is connected to the transmission main body 310 to rotate the transmission main body 310. The mounting bracket 340 supports the rotary drive device 301 upward. In this embodiment, the rotary drive device 301 can move linearly together with the transmission main body 310, so that the energized rotary drive device 301 can be disposed at a position other than the pot lid 4.

[0175] Specifically, the transmission support 330 may have a downward-facing support surface 332, which abuts against the linkage support surface 131. When the feeding bin 110 moves between the first position and the second position, the support surface 332 abuts against the linkage support surface 131 to enable the transmission assembly 300 to move smoothly. When the feeding bin 110 moves between the second position and the additional position, the support surface 332 separates from the linkage support surface 131.

[0176] The support surface 332 can be adapted to the shape of the linkage support surface 131, for example, it can be constructed as an inclined surface in the vertical direction, or optionally as an annular conical surface. The transmission support 330 can be provided with a support center hole 331 and a support boss 333 extending radially outward. It is understood that the support center hole 331 is located at the center of the transmission support 330. The feed bin 110 can be located within the support center hole 331, and the support surface 332 is arranged around the support center hole 331. The top of the transmission body 310 can be located between the support boss 333 and the mounting bracket 340, which can limit the linear movement of the transmission body 310 relative to the transmission support 330.

[0177] The top of the transmission body 310 may be provided with an upwardly protruding gear portion 314, which surrounds the central hole 331 of the support and has a ring of teeth. The output shaft is provided with a transmission gear 302, the teeth of which mesh with the teeth of the gear portion 314. The illustrated embodiment schematically shows one transmission gear 302 between the output shaft and the gear portion 314; however, the number of transmission gears 302 is not limited and can be set to two or more as needed.

[0178] The mounting bracket 340 may be provided with a bracket guide 341, which extends vertically. (See also: [link to previous section]) Figure 10 The storage bin 13 may be provided with a vertically extending guide wall 102. At least a portion of the guide wall 102 is located inside the storage bin 13 and connected to the fixed bracket 122 to isolate the transmission structure from the space for storing food. Figure 10 The diagram schematically shows the guide wall 102 connected to the bottom wall of the storage hopper 13, with a portion located above the bottom wall and a portion extending downwards from it. A support guide portion 341 is located within a sliding channel 46 enclosed by the guide wall 102. The mounting bracket 340 may include a bracket base 342 and a bracket stand 343 located above the bracket base 342. The bracket base 342 may have the support guide portion 341 integrally formed therewith. The support guide portion 341 may, for example, include three sequentially connected walls, with the bracket stand 343 located within a generally square area enclosed by these three walls. The bracket stand 343 is detachably connected to the bracket base 342 by fasteners such as screws. A rotary drive device 301 is mounted to the bracket stand 343 and is also located within the support guide portion 341. A support cylinder is provided in the middle of the bracket stand 343, and the output shaft of the rotary drive device 301 is located within the support cylinder. The lower end of the support cylinder abuts against a transmission gear 302 to restrict the axial movement of the transmission gear 302.

[0179] like Figure 5 , Figure 8 , Figure 21 and Figure 22As shown, the first rotation axis Ax1 can be collinear with the second rotation axis Ax2. The washing chamber 211 is centrally symmetrical; for example, the shape of the washing chamber 211 can be cylindrical. The central axis of the washing chamber 211 is collinear with the first rotation axis Ax1. Both the first rotation axis Ax1 and the second rotation axis Ax2 can extend vertically. The central axis of the washing chamber 211 can also extend vertically. Multiple rotating mating parts 232 can be spaced apart circumferentially along the mounting base 240, specifically spaced apart circumferentially along the second mounting base 250. Multiple rotating driving parts 322 are spaced apart circumferentially along the transmission body 310. The multiple rotating mating parts 232 have the same magnetism and are centrally symmetrically arranged around the first rotation axis Ax1. The multiple rotating driving parts 322 have the same magnetism and are centrally symmetrically arranged around the second rotation axis Ax2. The multiple rotating mating parts 232 are uniformly arranged circumferentially along the mounting base 240; the multiple rotating driving parts 322 are uniformly arranged circumferentially along the transmission body 310. Therefore, the magnetic force on the second mounting base 250 in the circumferential direction can be equal and uniform, thus ensuring that the first rotation axis Ax1 and the second rotation axis Ax2 remain collinear. The magnetic properties of the multiple rotating mating parts 232 can also be different, but the number of rotating mating parts 232 with different magnetic properties must be equal. Preferably, the rotating mating parts 232 with different magnetic properties are evenly and intermittently arranged, provided that the number is equal. For example, a group of rotating mating parts with the first magnetic property can be arranged first, then a group of rotating mating parts with the other magnetic property, then another group of rotating mating parts with the first magnetic property, then another group of rotating mating parts with the second magnetic property, and so on, intermittently, to ensure that adjacent groups of rotating mating parts have different magnetic properties but the same number, and that the number of magnets in each group is the same and greater than or equal to 1. The specific arrangement can be flexibly set according to needs; for example, the number can be two, three, four, five, or six, etc. For example, the total number of rotating mating parts 232 can be two and evenly arranged, with one magnet facing outward as the N pole and the other magnet facing outward as the S pole. Correspondingly, two rotating drive components can be set. Or, as... Figure 22 As shown, there are four groups of rotating mating parts, each with three magnets. The outward-facing poles of all three magnets in one group can be designated as N poles, and the outward-facing poles of all three magnets in adjacent groups can be designated as S poles. Therefore, the outward-facing poles of the rotating mating parts are NNN, SSS, NNN, and SSS, respectively. Correspondingly, the magnetism of the multiple mating rotating drive components 322 must also be different, but their numbers must be equal and they must be evenly and spaced. For example, in... Figure 22As shown, there are 16 rotating drive components, which can be arranged into 4 groups. In one group, the outward-facing magnetic poles of the four magnets are all designated as N poles, and the outward-facing magnetic poles of the four adjacent magnets are all designated as S poles. Therefore, the outward-facing magnetic poles of the rotating drive components are NNNN, SSSS, NNNN, and SSSS. During rotation, the outward-facing magnetic poles of the NNNN group of rotating drive components interact with the outward-facing magnetic poles of the SSS group of rotating mating components to generate magnetic force. Similarly, the outward-facing magnetic poles of the SSSS group of rotating drive components interact with the outward-facing magnetic poles of the NNN group of rotating mating components to generate magnetic force. This ensures that the second mounting base 250 experiences equal and uniform magnetic force in the circumferential direction.

[0180] The washing hopper assembly 200 may also include a limiting member. The mounting base 240 rotates around the limiting member, and the surfaces of the limiting member and the mounting base 240 abut against each other. In this embodiment, the second mounting base 250 drives the first mounting base 220 to rotate around the limiting member, which includes the inner sidewall 214 and the outer sidewall 215 of the washing hopper body 210.

[0181] The transmission body 310 is constructed in a centrally symmetrical shape, specifically a turntable shape as described above. The mounting base 240 is also constructed in a centrally symmetrical shape. Specifically, both the first mounting base 220 and the second mounting base 250 are cylindrical. In this embodiment, as described above, the mounting base 240 and the agitator 19 can be separate components, specifically the first mounting base 220 and the agitator 19 are separate components, to facilitate the installation of the washing hopper cover 270.

[0182] like Figure 21 As shown, when the transmission body 310 is in the first driving position and the second driving position, that is, when the rotary drive member 322 is in the driving position, the rotary drive member 322 and the rotary mating member 232 are radially aligned and their magnetic poles face opposite directions. At this time, the magnetic force between the rotary drive member 322 and the rotary mating member 232 is a magnetic attraction force, which causes the stirring member 19 to rotate. Figure 22 As shown, when the rotary drive 322 is in the drive position, it is radially offset from the rotary mating member 232, and their magnetic poles face each other. At this time, the magnetic force between the rotary drive 322 and the rotary mating member 232 is a magnetic repulsion force, which causes the stirring member 19 to rotate.

[0183] Multiple rotary drive components 322 are arranged at circumferential intervals along the transmission body 310. The transmission sidewall 312 has multiple transmission mounting surfaces 315 arranged circumferentially. Figure 10The transmission mounting surface 315 is planar and extends vertically, and the rotary drive member 322 is mounted to the transmission mounting surface 315. Multiple rotary mating members 232 are arranged at intervals along the circumference of the transmission body 310. The second mounting base 250 has multiple seat mounting surfaces 253 arranged circumferentially, the seat mounting surfaces 253 being planar and extending vertically, and the rotary mating members 232 are mounted to the seat mounting surfaces 253. One of the rotary mating members 232 and the rotary drive member 322 can be arranged in one row, and the other can be arranged in two rows at intervals along the vertical direction. Alternatively, both the rotary mating members 232 and the rotary drive member 322 can be arranged in one row, and one of them can be a vertically arranged elongated strip.

[0184] pot lid

[0185] See back Figures 13 to 15 The pot lid 4 includes a pot lid body and a washing chamber body 210 connected to the pot lid body. The pot lid body and the side wall portion 6 of the washing chamber body 210 are constructed as one piece, and the chamber body base 217 is detachably connected to the pot lid body. When the cooking utensil 1 is located... Figure 2 In the initial state shown, there is a gap between the transmission assembly 300 and the washing chamber assembly 200 on the lid 4. Using this gap, the user can lift the lid 4 and the pot body 2 together from the base 12 and remove them together, or the user can remove only the lid 4 from the pot body 2 to clean the washing chamber 211 and the agitator 19. The lid 4 is provided with a drainage structure communicating with the drain outlet 213 of the washing chamber body 210 and the wastewater tank 48, for draining washing water to the wastewater tank 48. Specifically, the drainage structure has a drainage pipe 10, which includes a drainage channel 105 and a pipe connector 106 located on the side wall 6, and a drainage pipe 107. The drainage channel 105 connects the drain outlet 213 and the pipe connector 106, and one end of the drainage pipe 107 is connected to the pipe connector 106, while the other end extends to the wastewater tank 48.

[0186] Optionally, as illustrated in the embodiment, the drain pipe 10 may include a siphon pipe with an inverted U-shaped structure. As an example, the drain channel 105 may be configured in an inverted U-shape as a siphon pipe. The pipe connector 106 is located in the middle of the side wall portion 6. This allows for siphon drainage. Alternatively, the drain structure may be configured such that the drain outlet 213 is level with or higher than the drain channel. This allows for gravity drainage. In this embodiment, water can flow by gravity from the washing chamber 211 to the wastewater tank 48 via the difference in water level, avoiding the use of a water pump. This reduces the number of internal components of the cooking appliance 1 and lowers production costs.

[0187] Alternatively, other sewage discharge methods can be adopted, such as setting up a separate solenoid valve for opening and closing the sewage outlet 213, and directly controlling whether to discharge by directly controlling the opening and closing state of the solenoid valve.

[0188] Optionally, the pot lid 4 may include a pot lid body and a removable cover (not shown) detachably connected to the pot lid body. Part or all of the drain pipe 10 may be detachably or non-detachably mounted on the removable cover. When the user wishes to clean the drain pipe 10, the removable cover can be removed for cleaning.

[0189] Return to reference Figure 1 and Figure 2 The cooking appliance 1 also includes a water inlet assembly for supplying water to the washing chamber 211. 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 be connected to the water inlet 113 of the feeding bin 110 via the water inlet pipe, and an electrically controlled valve may be installed between them to control the water inlet. The clean water in the clean water tank 81 can flow to the feeding bin 110 by gravity due to the water level difference, or it can be pumped to the feeding bin 110. The clean water tank 81 is detachably mounted on the body assembly 11, allowing for convenient water addition by the user. The clean water tank 81 is located near the storage mechanism and above the wastewater tank 48. The water inlet pipe may be located within the storage mechanism. Alternatively, if a water pump is installed, the water pump may also be located within the storage mechanism.

[0190] like Figure 1 and Figure 2 As shown, the main body assembly 11 also includes a main frame 101. The pot body 2 is located on the first side of the main frame 101. As shown above, the feeding mechanism 100 is used to transport the ingredients in the storage mechanism to the washing chamber 211. The storage mechanism, the feeding mechanism 100, and the transmission assembly 300 can all be located on the first side of the main frame 101 and above the washing chamber assembly 200. With this arrangement, the feeding mechanism 100 can be close to the storage mechanism, occupying space, and the material can be automatically fed into the washing chamber 211 by gravity, without the need for additional drive devices such as feeding pumps and feeding pipelines, reducing costs, simplifying the structure of the cooking appliance 1, and facilitating product miniaturization; the transmission assembly 300 can drive the stirring component 19 from above the washing chamber 211, thereby allowing the electrically powered drive device to be placed outside the pot lid 4, facilitating the user's cleaning operations on the pot lid 4 and the washing chamber assembly 200.

[0191] The water inlet assembly and the sewage discharge assembly can be located on a second side of the main frame 101, different from the first side. Specifically, the clean water tank 81 and the sewage tank 48 are located on the second side of the main frame 101. Figure 1The first and second sides of the main frame 101 are shown facing away from each other. The clean water tank 81 can be vertically aligned with the wastewater tank 48, that is, the clean water tank 81 is located directly above the wastewater tank 48. The clean water in the clean water tank 81 can flow by gravity to the feeding hopper due to the difference in water level, without the need for a booster pump.

[0192] The cooking appliance 1 may also include a main board and a display panel. The display panel may be located in the storage mechanism, specifically on the front side of the storage compartment 13. A control panel may be located on the outer side of the display panel. The main board may be located inside the main frame 101. The main board is located above the wastewater tank 48, on the side of the clean water tank 81 facing the pot body 2. The wastewater tank 48 may have a top opening to receive wastewater from the drain pipe 10 and to pour out water.

[0193] The cooking appliance 1 may also include an electrical device. This electrical device is located on the main frame 101, not on the lid 4 or the pot body 2. The electrical device includes a drive unit for driving the rotation and linear movement of the transmission assembly 300, a main board, a heating element, and a display panel. The electrical device can be located outside the lid 4 and pot body 2, facilitating user cleaning of the lid 4, the washing chamber assembly 200, and the inner pot of the pot body 2. Furthermore, waterproofing of the electrical device does not need to be considered during the manufacturing of the lid 4 and pot body 2.

[0194] The following text is for reference only. Figures 2-9 The entire washing process of the cooking appliance 1 according to the first embodiment is described as follows:

[0195] like Figure 2 As shown, the cooking appliance 1 is in its initial state. At this time, the feeding bin 110 and the transmission assembly 300 are both in their initial positions within the first position. The feeding bin 110 is not connected to the outlet of the storage bin 13 or the inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is in the closed position. In the initial state, the force relationship of the washing bin cover 270 is F1+F2≥G1+G2, where F1 is the magnetic force between the translational mating part 231 and the translational driving part 321; F2 is the magnetic force between the holding member 237 and the holding mating part 238; G1 is the total weight of the washing bin cover 270 and the follower load that moves with it in a straight line. In this embodiment, the follower load includes at least the first mounting base 220, the translational mating part 231, and the stirring member 19; G2 is the weight of the water and materials in the washing chamber 211. It can be understood that G1 is a fixed value, and F1, F2, and G2 are variable values. In this state, F1 is small, and may even be close to or equal to 0. When F1 = 0, F2 ≥ G1 + G2; F2 is the largest, i.e., F2max; G2 = 0, or G2 is the weight of a small amount of residual water after cleaning on the washing chamber 211.

[0196] When the material feeding operation is to be performed, the linear drive device 120 first drives the screw 121 to move, thereby the screw 121 drives the feeding bin 110 downward to the first drive position in the second position. For example... Figure 3 As shown, the cooking appliance 1 is in the preparation to feed ingredients. At this time, both the feeding bin 110 and the transmission assembly 300 are in the first drive position of the second position. The feeding bin 110 is still not connected to the outlet of the storage bin 13 and the inlet 201 of the washing bin assembly 200, and the washing bin cover 270 is still in the closed position. Figure 3 In the shown state, the force relationship of the washing hopper cover 270 is F1+F2>G1+G2, where F1 and F2 are at their maximum, i.e., F1max and F2max, and G2 is the same as in the initial state. Therefore, the washing hopper cover 270 is subjected to an upward magnetic force, and the washing hopper assembly 200 is radially magnetically connected. Then, the linear drive device 120 can continue to drive the screw 121, and the feeding hopper 110 continues to move downward and extend into the washing chamber 211, while the transmission assembly 300 does not move accordingly. Figure 4 As shown, the cooking appliance 1 is in the feeding state. At this time, the feeding bin 110 is in the auxiliary position, the transmission component 300 is in the first drive position of the second position, and the feeding bin 110 is still connected to the outlet of the storage bin 13 and the inlet 201 of the washing bin component 200. The washing bin cover 270 is still in the closed position. The material in the storage bin 13 enters the feeding bin 110 through the inlet 111, and then enters the washing chamber 211 through the outlet 112 to perform the feeding action. The amount of material flowing into the washing chamber 211 can be calculated by time. The cooking appliance controls the time when the feeding bin 110 is in the auxiliary position according to the amount of material required by the user to achieve quantitative feeding. Water can also be supplied to the washing chamber 211 in this feeding state. Feeding and water supply can be carried out simultaneously, or water supply can be carried out after feeding is completed. The clean water in the clean water tank 81 enters the feeding hopper 110 through the pipeline and the water inlet 113, and then enters the washing chamber 211 through the water outlet 114. When the feeding and water supply are completed, the force relationship of the washing hopper cover 270 is F1+F2>G1+G2, where F1 and F2 are F1max and F2max, and G2 is the weight of water and material.

[0197] When the feeding operation is completed, the linear drive device 120 drives the screw 121 to move again. The screw 121 drives the feeding bin 110 to move upward to the first drive position in the second position, as shown. Figure 5 As shown. In Figure 5 In the state shown, water can be supplied to the washing chamber 211, or it can also be... Figure 4 Water is supplied to the washing chamber under the specified condition. When... Figure 5When water is supplied in the state shown, the weight of G2 increases. After the water supply is completed, the rotary drive device 301 can drive the transmission main body 310 to rotate. Furthermore, the magnetic force between the rotary drive member 322 and the rotary mating member 232 can drive the second mounting seat 250 to rotate, and then drive the first mounting seat 220 and the stirring member 19 thereon to rotate together to perform the material washing action. It can be understood that for the illustrated embodiment, when performing the material washing action, the water level in the material washing chamber 211 is lower than the highest part of the sewage discharge pipe 10. In other embodiments not shown, an electromagnetic valve for separately opening and closing the sewage discharge port 213 can be provided, and the drainage can be directly controlled by directly controlling the opening and closing state of the electromagnetic valve. This drainage method does not limit that the water level in the material washing chamber 211 must be lower than the highest part of the sewage discharge pipe.

[0198] For the illustrated embodiment, when intending to drain water after the material washing action is completed, first supply water to the material washing chamber 211 until the water level in the material washing chamber 211 is higher than the highest part of the sewage discharge pipe 10, and use the siphon principle to drain water. And there will be a velocity head at the highest position of the drainage channel, thereby forming a full flow in the sewage discharge pipe 10. When the water level drops to below the highest position of the sewage discharge pipe 10, since the drainage channel is already in a full flow state at this time, and since the water level in the material washing chamber 211 is higher than the water level of the water outlet 114 of the sewage discharge pipe 107, according to Bernoulli's principle, there will be a velocity head at the outlet of the sewage discharge pipe 107 at this time, and the water in the material washing bin can be drained completely. When the drainage is completed, the force relationship of the material washing bin cover 270 is F1 + F2 > G1 + G2, where F1 and F2 are F1max and F2max, and G2 is the weight of the water-absorbed material and a small amount of residual water. If necessary, clean water can also be added after drainage for cooking; in this case, G2 is the weight of the water-absorbed material and clean water.

[0199] The actions of water supply, material washing, throwing off materials during washing, and drainage can be repeatedly executed to achieve multiple material washings for a single batch of materials.

[0200] When intending to discharge materials after the drainage action is completed, the linear drive device 120 drives the feeding bin 110 to move upward to the middle position of the first position, as Figure 6 shown. In the Figure 6 state shown, the force relationship of the material washing bin cover 270 is F1 + F2 < G1 + G2, where F1 decreases, that is, F1 < F1max, F2 is F2max, and G2 is the same as when the drainage is completed. Since F1 + F2 < G1 + G2, the material washing bin cover 270 is unbalanced in force and cannot remain in the closed position and will move downward, and the discharge port 212 will open. The cooking appliance quickly switches from the Figure 6 state shown to the Figure 7 state shown, that is, the material washing bin cover 270 moves downward to the open position. During this process, F1 continues to decrease and F2 decreases. As Figure 7 As shown, the washing material bin cover 270 is already in the open position and the discharge opening 212 is open. At this time, some materials and / or water will fall into the inner pot 3, and G2 decreases. Figure 7 In the state shown, the force relationship of the washing material bin cover 270 is F1 + F2 < G1 + G2, where F1 < F1max, F2 is the minimum, that is, F2min, and G2 is the weight of the remaining water-absorbing materials and a small amount of residual water. Then the linear drive device 120 drives the screw 121 to move the transmission main body 310 downward from the middle position to the second drive position in the second position. At this time, as Figure 8 shown, the cooking appliance 1 is in the material dropping state. There is a distance d1 between the translational drive member 321 and the translational mating member 231, and the force relationship of the washing material bin cover 270 is F1 + F2 < G1 + G2, where F1 < F1max, F2 is F2min, and G2 is Figure 7 the same as the state shown, so that during the material dropping process, the washing material bin cover 270 always remains in the open position. Then the rotary drive device 301 drives the transmission main body 310 to rotate again, causing the stirring member 19 to rotate, starting to throw the materials, and performing the material dropping action. The materials fall into the inner pot 3 quickly under the action of centrifugal force. When throwing the materials, G2 continues to decrease. After the material throwing is completed, the force relationship of the washing material bin cover 270 is F1 + F2 < G1 + G2, where 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 can be 30 g.

[0201] When it is necessary to perform resetting after the material dropping action is completed, the linear drive device 120 continues to drive the screw 121 to move the transmission main body 310 from the second drive position to the first drive position. As Figure 9 shown, during this process, F1 increases. At this time, there is a distance d2 between the translational drive member 321 and the translational mating member 231, and d2 is less than d1. The force relationship of the washing material 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 washing material bin cover 270 will move upward to the closed position under the action of magnetic force. For example, Figure 3 as shown, the resetting of the washing material bin cover 270 is realized. The cooking appliance quickly switches from the Figure 9 state shown to the Figure 3 state shown, that is, the washing material bin cover 270 moves upward to the closed position. During this process, F1 continues to increase to F1max, F2 increases to F2max, and G2 is Figure 9 the same as the state, and at this time F1 + F2 > G1 + G2.

[0202] The various actions in the process from feeding to material dropping can be repeatedly executed to realize the washing of materials multiple times; that is, the Figures 3 to 9 states shown are repeatedly executed.

[0203] Then the linear drive device 120 drives the feeding bin 110 upward to the initial position in the first position, such as Figure 2 As shown, this process achieves the reset of the feeding bin 110 and the transmission assembly 300. During this process, F1 decreases to a small value, possibly even close to or equal to 0, F2 becomes F2max, and G2... Figure 9 When the states are the same, F1+F2>G1+G2.

[0204] Second Implementation Method

[0205] The following is for reference Figures 23 to 24 The cooking appliance of the second embodiment will now be described. Except for the transmission structure, the stirring element 19, and the washing chamber cover 270, the cooking appliance of the second embodiment has the same structure and / or construction as the cooking appliance 1 of the first embodiment. Therefore, components having substantially the same function as those in the first embodiment will be numbered the same here, and for the sake of brevity, they will not be described in detail and / or illustrated further.

[0206] In this embodiment, such as Figure 23 As shown, the discharge port 212 is normally closed. The washing chamber fitting 230 is located inside the washing cavity 211; that is, the translational fitting 231 and the rotary fitting 232 are located inside the washing cavity 211 and are mounted on the same mounting base 240. In other words, the first and second mounting bases are formed as a single unit, and one mounting base 240 is provided. The agitator 19 and the washing chamber cover 270 are either integrally formed or separate components, with the agitator 19 fixedly connected to the washing chamber cover 270. Thus, the washing chamber cover 270 moves linearly and rotates with the agitator 19. The rotary drive 322 is located radially inside the rotary fitting 232 in the driving position. The translational drive 321 and the rotary drive 322 are located in the same transmission body.

[0207] The mounting base 240 is located within the washing chamber 211 and includes a mounting base 221 and a mounting sleeve 222 connected to the mounting base 221. A washing chamber cover 270 and a translational fitting 231 may be disposed on the mounting base 221, and a rotational fitting 232 is disposed on the top of the mounting sleeve 222. The washing chamber body 210 includes a tank portion 225 forming a receiving groove 226, located within the washing chamber 211. A transmission body 310 is located within the receiving groove 226, and the tank portion 225 is located within the mounting sleeve 222. The mounting sleeve 222 is movably disposed within the tank portion 225; specifically, the mounting base 240 moves linearly relative to the tank portion 225 and rotates about the tank portion 225. For example, the mounting sleeve 222 may engage with the radial outer surface of the tank portion 225.

[0208] The transmission assembly 300 also includes a mounting bracket 340 and a rotary drive device 301. The rotary drive device 301 is disposed on the mounting bracket 340, and its output shaft is connected to the transmission body 310 to rotate the transmission body 310. In the illustrated embodiment, the output shaft is directly inserted into the mounting hole of the transmission body 310.

[0209] In the illustrated embodiment, such as Figure 24 As shown, the retaining member 237 and the retaining mating member 238 can be located inside the washing chamber 211. Specifically, the retaining member 237 can be located at the bottom of the tank portion 225.

[0210] Furthermore, in embodiments not shown, a separate water supply pipe communicatively connected to the washing chamber 211 can be provided to directly supply water to the washing chamber 211. This allows water to be supplied to the washing chamber 211 at any stage of the entire washing process. A feeding device communicatively connected to the washing chamber 211 can be provided. This feeding device may remain stationary relative to the storage hopper 13 and includes a feeding component such as a rotating screw to feed material into the washing chamber 211.

[0211] It should be noted that the force relationship mentioned in this article can be understood as the force relationship of the component consisting of the washing hopper cover 270 and the follower load that moves with it in a straight line. For the sake of simplicity, it is simply referred to as the force relationship of the washing hopper cover 270. Similarly, the descriptions of the washing hopper cover 270 being subjected to magnetic force, physical force, magnetic force, gravity, etc. can be understood as various descriptions of the forces of the component consisting of the washing hopper cover 270 and the follower load that moves with it in a straight line. For the sake of simplicity, it is simply referred to as the washing hopper cover 270. As an example, the magnetic force on the washing hopper cover 270 can be understood as the magnetic force on the component consisting of the washing hopper cover 270 and the follower load that moves with it in a straight line.

The processes described in all the preferred embodiments above are merely examples.
