Description

Technical Field

[0001] This invention relates to the technical field of kitchen appliances, and more specifically to a washing assembly, a pot lid, a cooking utensil, and a control method for the cooking utensil. Background Technology

[0002] Existing cooking appliances, such as automatic rice cookers, typically have a separate washing compartment. Food to be cooked can be washed in this compartment for user convenience. The washing compartment usually has a drain outlet and a sealing structure to block it. During washing, the drain outlet is sealed by the sealing structure; when drainage is desired, the sealing structure is opened to release the wastewater. However, existing sealing structures are relatively complex.

[0003] Therefore, there is a need for a washing assembly, a pot lid, a cooking appliance, and a control method for the cooking appliance to at least partially solve the above problems. Summary of the Invention

[0004] 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.

[0005] To at least partially solve the above-mentioned problems, a first aspect of the present invention provides a washing assembly, the washing assembly comprising a main body and a washing chamber cover movably disposed within the main body, the main body forming a washing chamber and having a drain outlet and a discharge outlet, the washing chamber cover being movable between an open position (opening the discharge outlet) and a closed position (closing the discharge outlet).

[0006] The washing hopper cover also has a communicating position and a sealed position. When the washing hopper cover is in the communicating position, the drain outlet is connected to the washing chamber. When the washing hopper cover is in the sealed position, the drain outlet is not connected to the washing chamber.

[0007] According to the above solution, the washing hopper cover can move between an open and closed position, thus effectively sealing the discharge port. Furthermore, the washing hopper cover can also function as a drain valve. During washing, the cover is in a closed position; when draining, it is in a connected position, allowing wastewater to drain through the outlet. This solution is dual-purpose, simple, convenient, and inexpensive. Moreover, it eliminates the need for a separate drain valve, preventing the washing hopper cover from becoming electrified and affecting the washing process.

[0008] Optionally, the washing assembly includes a sidewall portion that forms a washing chamber having the discharge port, and the drain port is disposed on the sidewall portion.

[0009] This solution facilitates the manufacturing of the washing components and also simplifies the washing and drainage operations.

[0010] Optionally, the washing hopper cover includes a sealing portion, wherein when the washing hopper cover is in the closed position, the outer periphery of the sealing portion seals against the inner periphery of the side wall portion.

[0011] This solution can increase the sealing area and the sealing range, achieving a more stable seal.

[0012] Optionally, when the washing hopper cover is in the communicating position, the washing hopper cover is located below the drain outlet within the main body; when the washing hopper cover is in the sealed position, the washing hopper cover is located above the drain outlet within the main body.

[0013] This design facilitates assembly and manufacturing.

[0014] Optionally, the washing assembly further includes a drain pipe connected to the drain outlet.

[0015] This solution facilitates the discharge of wastewater generated during material washing by installing sewage pipes.

[0016] Optionally, the position of the drain pipe in the height direction of the washing assembly is not higher than the position of the drain outlet in the height direction.

[0017] This design allows wastewater to fall from the discharge outlet into the sewage pipe by gravity.

[0018] Optionally, the washing assembly further includes an agitator that is rotatable relative to the washing hopper cover.

[0019] This solution can achieve automatic cleaning of materials and clean them more thoroughly.

[0021] Optionally, the washing assembly further includes a drive shaft that can be driven to rotate and move up and down. The drive shaft can cooperate with the washing assembly to drive the agitator to rotate and drive the washing hopper cover to move up and down between the open position and the closed position.

[0022] In this design, the drive shaft component can both rotate and move up and down, thereby enabling it to drive the agitator to rotate and drive the washing hopper cover to open or close the discharge port. This simplifies the structure of the cleaning device, making it more compact and reducing its space requirements.

[0023] Optionally, the sidewall portion is constructed as a straight wall.

[0024] This solution facilitates material discharge and reduces material residue, while also enabling dynamic sealing between the washing hopper cover and the side wall.

[0026] According to the above scheme, the washing hopper cover can move between an open and closed position, thereby sealing the discharge port. Furthermore, the washing hopper cover can also be used as a drain valve. During washing, the cover is in a closed position; when draining, it is in a connected position, allowing wastewater to drain through the drain port. This design is dual-purpose, simple, convenient, and inexpensive. Moreover, the above scheme eliminates the need for a separate drain valve, preventing the washing hopper cover from becoming electrified and affecting cleaning. Additionally, by placing the washing assembly inside the pot lid, cleaning is convenient.

[0027] Optionally, the washing assembly includes a sidewall portion disposed on the pot lid and forming the main body. This design facilitates assembly and manufacturing.

[0028] Optionally, the washing assembly further includes a drain pipe, which is at least partially disposed within the pot lid. This design facilitates cleaning of the drain pipe.

[0029] Optionally, the pot lid includes a pot lid body and a detachable cover detachably connected to the pot lid body, and the drain pipe is at least partially disposed on the detachable cover.

[0030] According to this solution, the drain pipe is at least partially installed on the removable cover, which is detachably connected to the pot lid body. Therefore, when the user wishes to clean the drain pipe, they only need to remove the removable cover, making it convenient for the user. Furthermore, this solution is easy to assemble and inexpensive.

[0031] Optionally, the sewage pipe is detachably connected to the removable cover.

[0032] This solution allows the sewage pipe to be removed from the removable cover, thus making it easier to clean the sewage pipe.

[0033] Optionally, the drain pipe includes a support portion and a cover portion. The cover portion is connected to the pot lid body, and the support portion is connected to the detachable lid. The position of the support portion corresponds to the position of the cover portion, and the cover portion can be connected to the support portion to form the drain pipe.

[0034] According to the above solution, when cleaning the drain pipe, simply remove the removable cover from the main body of the pot lid to clean both the upper and lower parts of the drain pipe. This solution makes cleaning the drain pipe more convenient and thorough. Furthermore, this solution is easy to manufacture, convenient to assemble, and has a low cost.

[0035] Optionally, the sewage pipe further includes a seal disposed between the support portion and the cover portion.

[0036] This solution can prevent sewage from leaking from the drain pipe into the inside of the pot lid.

[0037] Optionally, the seal is detachably attached to the cover.

[0038] This solution facilitates the cleaning of the seals.

[0039] Optionally, the detachable cover has an inner ring portion, which is fitted onto the side wall portion, and a sealing structure is provided between the inner ring portion and the side wall portion, with the inner ring portion located below the drain outlet.

[0040] This solution can prevent wastewater from washing materials from flowing into the inner pot.

[0041] Optionally, the drain pipe includes a first pipe and a second pipe communicating with the first pipe, the first pipe being arranged in a ring around the side wall portion, and the second pipe extending from the first pipe along the radial direction of the pot lid to the outer periphery of the pot lid.

[0042] This solution can improve drainage efficiency, and it is easy to manufacture, easy to assemble, and has a low cost.

[0043] Optionally, the main body includes a plurality of drain outlets disposed on the side wall portion, the plurality of drain outlets being arranged at intervals along the circumferential direction of the side wall portion.

[0044] This solution can accelerate drainage speed and improve drainage efficiency. Furthermore, it is easy to manufacture, convenient to assemble, and has a low cost.

[0045] Optionally, the main body includes a drain outlet disposed on the side wall portion, and the drain pipe extends from the drain outlet along the radial direction of the pot lid to the outer periphery of the pot lid.

[0046] This solution is easier to manufacture and has a lower cost.

[0047] According to a third aspect of the present invention, a cooking utensil is also provided, comprising:

[0048] The pot body; and

[0049] The pot lid as described above is attached to the pot body.

[0050] According to the above scheme, the washing hopper cover can move between an open and closed position, thereby sealing the discharge port. Furthermore, the washing hopper cover can also be used as a drain valve. During washing, the cover is in a closed position; when draining, it is in a connected position, allowing wastewater to drain through the drain port. This design is dual-purpose, simple, convenient, and inexpensive. Moreover, the above scheme eliminates the need for a separate drain valve, preventing the washing hopper cover from becoming electrified and affecting cleaning. Additionally, by placing the washing assembly inside the pot lid, cleaning is convenient.

[0051] Optionally, the lid is detachably attached to the pot body. This design allows users to easily remove and clean the lid.

[0052] Optionally, the washing assembly further includes a drain pipe, and the cooking appliance further includes a wastewater tank. The drain pipe is provided with a connecting pipe extending toward the wastewater tank, and the wastewater tank is connected to the drain pipe via the connecting pipe, with the wastewater tank located below the drain pipe. This design facilitates wastewater falling into the wastewater tank by gravity.

[0053] In another aspect, the present invention provides a control method for a cooking appliance as described above, the control method comprising:

[0054] Controlling the washing chamber cover to the sealed position at at least one stage of the cooking process allows washing operations to be performed within the washing chamber; and

[0055] During at least one stage of the cooking process, the washing chamber cover is controlled to be in the communicating position, so that the wastewater in the washing chamber is discharged through the drain port.

[0056] According to the above design, the washing hopper cover can move between an open and closed position, thus effectively sealing the discharge port. Furthermore, the washing hopper cover can also function as a drain valve. During washing, the cover is in a closed position; during wastewater discharge, it is in a connected position, allowing wastewater to drain through the outlet. This design is dual-purpose, simple, convenient, and inexpensive.

[0057] Optionally, the control method further includes:

[0058] During at least one stage of the cooking process, the washing chamber cover is controlled to be in the sealed position, so that the steam in the cooking chamber is discharged through the drain port.

[0059] According to the control method described above, the drain outlet can be used as a steam exhaust outlet, which is convenient for steam exhaust, easy to assemble, and inexpensive.

[0060] Optionally, the control method further includes:

[0061] During at least one stage of the cooking process, the washing chamber cover is controlled to be in the communicating position, so that the cooking chamber is kept under pressure.

[0062] This design allows the drain outlet to be conveniently used as a steam outlet. When it is desired to maintain pressure in the cooking chamber, the washing chamber cover can be placed in the connected position.

[0063] Optionally, the control method further includes:

[0064] The position of the washing chamber cover is adjusted at at least one stage of the cooking process so that the portion of the drain outlet communicating with the cooking chamber is variable.

[0065] This solution allows for adjustment of the size of the drain outlet connected to the cooking chamber by adjusting the position of the washing chamber cover, thereby making the pressure in the cooking chamber adjustable. Attached Figure Description

[0104] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the invention.

[0105] To fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0106] This invention provides a washing assembly, a pot lid, a cooking appliance, and a control method for the cooking appliance. The cooking appliance according to this invention can be a rice cooker, an electric pressure cooker, or other cooking appliances, and in addition to cooking rice, it can also have various functions such as cooking porridge, making soup, and stir-frying. Preferred embodiments of the invention are described below with reference to the accompanying drawings.

[0107] It should be noted that the directional terms such as "up," "down," "high," "low," "front," and "back" used in this article are based on the position of the cooking utensil when it is placed on a horizontal table, with the lid closed, and the user is using the cooking utensil. Specifically, the direction in which the cooking utensil faces the user is defined as "front," and the opposite direction is defined as "back."

[0108] The cooking appliance 1 of the present invention will now be described in detail with reference to the accompanying drawings.

[0109] refer to Figure 1 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.

[0110] The pot assembly includes a pot body 2, an inner pot 3 disposed within the pot body 2, and a lid 4 covering 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, thereby facilitating cleaning of the lid 4. When the lid 4 is closed onto the pot body 2, a cooking cavity is formed between the lid 4 and the inner pot 3.

[0111] The base 12 typically houses a heating device (not shown) 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, such that when energized, the heating device generates 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 configured as a battery housed in the base 12.

[0112] refer to Figure 2 -and Figure 7The machine body assembly 11 also includes a storage mechanism 89 and a feeding mechanism 15. The storage mechanism 89 includes a storage bin 13, which can store ingredients such as rice, millet, mung beans, corn kernels, black beans, red beans, and so on. The storage bin 13 has a side outlet 14, meaning that the outlet 14 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 14 is located at the lower part of the storage bin 13, which further facilitates the outflow of materials from the storage bin 13 through the outlet 14 by gravity.

[0113] Continue to refer to Figure 2 -and Figure 7 The feeding mechanism 15 includes a feeding bin 16, which has a feeding inlet 88 (e.g., ...). Figure 15 As shown), the discharge port 82 is located below the feed inlet 88 (as shown). Figure 19 (as shown) and a vertically extending feed channel (not shown) disposed between the feed inlet 88 and the discharge outlet 82. The feed inlet 88 is disposed on the side wall of the feed bin 16, and the discharge outlet 82 is disposed on the bottom wall of the feed bin 16. The feed bin 16 is at least in the first position (i.e., the initial state, such as...) Figure 2 As shown) and the second position (that is, the lower position, such as Figure 3 The feed hopper 16 is movable between the outlet 14 and the inlet 7 of the washing assembly 5 (as shown), wherein when the feed hopper 16 is in the first position, the feed hopper 16 is movable between the outlet 14 and the inlet 7 of the washing assembly 5 (as shown). Figure 9 As shown in the diagram (described below), the feed hopper 16 is not connected to the outlet 14 and the inlet 7 when the feed hopper 16 is in the second position. When in the feeding state (e.g., ...), the feed hopper 16 is connected to both the outlet 14 and the inlet 7. Figure 3 As shown, the inlet 88 can be connected to the outlet 14 of the storage bin 13, and the outlet 82 can be connected to the inlet 7 of the washing assembly 5, so that the material in the storage bin 13 enters the feeding bin 16 through the inlet 88, and then enters the washing assembly 5 through the outlet 82. The feeding bin 16 is generally constructed as a columnar structure.

[0114] The feeding mechanism 15 is at least partially located within the storage silo 13, or at least partially located outside the storage silo 13 but within the space enclosed by the storage silo 13. The "enclosed space" referred to here means that, in any coordinate system, projections along the X, Y, and Z directions will overlap. In the illustrated embodiment, as... Figure 2 As shown, when the feeding bin 16 is in the first position, the feeding bin 16 is hidden in the storage bin 13, as... Figure 3 As shown, when the feeding bin 16 is in the second position, the feeding bin 16 extends out from the storage bin 13. This design hides the feeding bin 16 inside the storage bin 13 when it is in the first position, which can prevent the feeding bin 16 from being damaged and also make the structure of the cooking appliance more compact.

[0115] Preferably, the storage bin 13 is further provided with a sliding channel 46, and the feeding mechanism 15 is movably disposed in the sliding channel 46. This design ensures that the feeding mechanism 15 moves up and down in a predetermined direction within the storage bin 13, preventing the feeding mechanism 15 from shifting during movement.

[0116] Washing components

[0117] like Figure 2-7 as well as Figure 8-10 As shown, the cooking appliance 1 also includes a washing assembly 5, which is disposed within the lid 4. Since the lid 4 is removable, placing the washing assembly 5 within the lid allows it to be removed and washed together with the lid 4. The washing assembly 5 is located below the storage compartment and on the same side of the machine body as the lid. Preferably, the washing assembly 5 is detachably disposed within the lid 4 to facilitate disassembly and washing. The washing assembly 5 includes a main body 52 with a discharge port 8. The main body 52 has a washing chamber, through which washed rice can be discharged. The main body 52 also has a feed inlet 7, through which material from the feeding compartment 16 described above can enter the washing chamber.

[0118] The washing assembly 5 includes a side wall portion 6. The side wall portion 6 is disposed on the pot lid 4 and forms the main body 52, surrounding a washing chamber with a discharge port 8. 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. This design facilitates manufacturing and assembly. The side wall portion 6 is constructed as a straight wall. In the illustrated embodiment, the side wall portion 6 is configured to extend vertically, so that the washing chamber has the same width from top to bottom. In other embodiments not shown, the side wall portion 6 may also be configured to extend obliquely from top to bottom toward the interior of the washing chamber, i.e., the washing chamber is wider at the bottom and narrower at the top, to reduce rice grain residue. Furthermore, the inner surface of the side wall portion 6 is configured as a smooth surface to further reduce rice grain residue. The washing assembly 5 also includes a stirring assembly 18 disposed in the main body 52 and a washing chamber cover 17 disposed below the stirring assembly 18.

[0119] The washing hopper cover 17 is movably disposed within the main body 52. ​​Specifically, the washing hopper cover 17 is movable between an open position where the discharge port 8 is opened and a closed position where the discharge port 8 is closed. Figure 2-6 As shown, the washing hopper cover 17 is located at the top, in the closed position covering the discharge port 8; as Figure 7 As shown, the washing chamber cover 17 moves downwards to the open position of the discharge port 8, at which time the rice in the washing chamber can fall into the inner pot 3 through the discharge port 8.

[0120] The mixing assembly 18 includes a mixing element 19, which is connected to the washing hopper cover 17. The mixing element 19 and the washing hopper cover 17 can move together between an open position and a closed position, and the mixing element 19 is rotatable relative to the washing hopper cover 17, that is, when the mixing element 19 rotates, the washing hopper cover 17 does not rotate.

[0121] In one embodiment, the agitator 19 can rotate during the washing and rice-spinning operations. Preferably, the agitator 19 is provided with a conical guide surface that slopes outward from top to bottom along the radial direction of the agitator 19. This design allows the rice on the agitator 19 to be more easily spinned out during rotation, in addition to the centrifugal force, thanks to the inclined guide surface. Furthermore, the inclined guide surface facilitates the downward sliding of the rice, reducing residual rice in the washing chamber.

[0122] Preferably, such as Figure 33 As shown, the upper surface of the stirring component 19 is also provided with turbulence ribs 71 and turbulence columns 72. The combination of turbulence ribs 71 and turbulence columns 72 can turbulentize the rice and water in the washing chamber during rotation, thereby cleaning the rice more thoroughly. It is understood that those skilled in the art can also provide only turbulence ribs 71 or only turbulence columns 72 as needed.

[0123] Continue to refer to Figure 33 In the illustrated embodiment, the turbulence column 72 is cylindrical and vertically arranged. In other embodiments not shown, the turbulence column 72 may also be arranged obliquely, either inclined or perpendicular to the agitator 19, or the cross-sectional shape of the turbulence column 72 may be square, rhomboid, elliptical, polygonal, etc. The turbulence column 72 may be integrally formed with the agitator 19, or it may be two separate components from the agitator 19.

[0124] Preferably, the turbulence column 72 and the agitator 19 are made of different materials to achieve the best mixing effect, thereby reducing residual rice. Those skilled in the art can set the number of turbulence columns 72 according to actual needs; for example, one column or multiple columns can be set.

[0125] like Figure 42 As shown, preferably, the stirring component 19 is provided with two baffle columns 72, which are connected at the same position of the stirring component 19 and extend in different directions.

[0126] Preferably, the height and width of the deflector 71 are less than 10 mm. For example... Figure 38-41 As shown, the baffle 71 can be constructed as a straight line, an arc, an S-shape, etc., and the number of baffle 71 can be one or multiple.

[0127] In a preferred embodiment, such as Figure 11-12 as well as Figures 29-31 As shown, the washing hopper cover 17 includes a cover plate 53, an additional cover plate 54, and a sealing portion 47 disposed between the cover plate 53 and the additional cover plate 54. The cover plate 53 is connected to the agitator 19 below the agitator 19, and the outer periphery of the sealing portion 47 seals against the inner periphery of the side wall portion 6.

[0128] In a preferred embodiment, the sealing portion 47 is constructed as a sheet and is sandwiched between the cover plate 53 and the additional cover plate 54. In the clamped state, a portion of the outer periphery of the sealing portion 47 protrudes from the cover plate 53 and the additional cover plate 54, thereby forming a seal with the sidewall portion 6. The sealing portion 47 can be made of soft rubber such as rubber or silicone, while the cover plate 53 and the additional cover plate 54 are preferably made of hard rubber to avoid deformation caused by using only soft rubber for the entire washing hopper cover 17. Exemplarily, the cover plate 53, the sealing portion 47, and the additional cover plate 54 can be fixed together by screws. In this embodiment, the washing hopper cover 17 does not rotate with the agitator 19, thereby preventing wear on the sealing portion 47. Further preferably, as... Figure 12 As shown, the minimum axial clearance D between the sealing part 47 and the stirring part 19 is less than 2 mm.

[0129] In another preferred embodiment, such as Figure 36 As shown, the sealing part 47' can also be constructed as a ring and fitted around the outer periphery of the cover plate 53. The sealing part 47' can be constructed as a separate part from the cover plate 53, or it can be integrally formed with the cover plate 53 by secondary injection molding.

[0130] like Figure 37 As shown, in another embodiment, when the sealing part 47” is made of a wear-resistant material, the sealing part 47” can be directly sleeved on the outer periphery of the stirring member 19 and rotate together with the stirring member 19, or the sealing part 47” can be injection molded into a single piece with the stirring member 19.

[0131] like Figures 29-35 As shown, the stirring assembly 18 also includes a limiting portion 56, which has a circular cross-section. The limiting portion 56 includes a protrusion 57 and a peripheral portion 58 surrounding the protrusion 57, which is spaced apart from the protrusion 57 in the radial direction of the limiting portion 56. The protrusion 57 has a non-circular cross-section; for example, in the illustrated embodiment, the protrusion 57 has a square cross-section.

[0132] A connecting port 55 is provided on the stirring member 19, extending through the stirring member 19 along its height direction. The stirring member 19 has a downwardly extending hollow sleeve portion 59, the hollow portion of which forms part of the connecting port 55. The stirring member 19 also has a downwardly opening recess 60, into which the sleeve portion 59 extends. A limiting portion 56 is connected to the connecting port 55 below it. Specifically, the protrusion 57 of the limiting portion 56 is inserted into the connecting port 55, and the peripheral portion 58 is fitted around the outer periphery of the sleeve portion 59. Preferably, the cross-sectional shape of the connecting port 55 matches the cross-sectional shape of the protrusion 57, and is non-circular, so that the stirring member 19 can rotate together with the limiting portion 56. In the illustrated embodiment, the cross-section of the connecting port 55 is square.

[0133] like Figure 29 and 30 As shown, the cover plate 53 is provided with a connector 61 protruding outward along its axial direction. The connector 61 protrudes toward the recess 60 and extends into the recess 60, abutting the peripheral portion 58 of the limiting portion 56. In a preferred embodiment, the connector 61 includes an axially extending portion 62 extending axially from the cover plate 53 and a radially extending portion 63 extending inwardly from the end of the axially extending portion 62 along the radial direction of the cover plate 53. The axially extending portion 62 has a circular cross-section and extends into the recess 60. In the assembled state, it is connected... Figure 11 and 12 As shown, the radial extension 63 extends between the bottom of the recess 60 and the peripheral edge 58 of the limiting portion 56, with the upper surface of the radial extension 63 adjacent to the bottom of the recess 60 and the lower surface adjacent to the top of the peripheral edge 58. This arrangement allows the stirring member 19, the limiting portion 56, and the cover plate 53 to move up and down together.

[0134] refer to Figure 26-28 Preferably, the washing assembly 5 further includes a top cover 20, which can be closed onto the side wall portion 6, and the inlet 7 is provided on the top cover 20. Preferably, the top cover 20 is detachably connected to the side wall portion 6 to facilitate the disassembly and washing operation of the washing assembly 5.

[0135] In a preferred embodiment, a limiting protrusion 64 is provided on the side wall portion 6, and the top cover 20 includes a top cover body 65 and a ring extension 66 extending downward from the periphery of the top cover body 65. A limiting opening is provided on the extension 66, wherein the limiting protrusion 64 can cooperate with the limiting opening to fix the top cover 20 on the side wall portion 6.

[0136] Furthermore, the limiting opening is generally L-shaped and includes a guide opening 67 and a limiting opening 68 extending approximately perpendicular to the guide opening 67, with the limiting opening 68 communicating with the guide opening 67. The guide opening 67 allows the limiting protrusion 64 to enter the limiting opening 68. In the illustrated embodiment, the limiting protrusion 64 is elongated, and the dimension of the guide opening 67 in the circumferential direction of the top cover 20 is slightly larger than the length of the limiting protrusion 64, so that the limiting protrusion 64 can smoothly enter the guide opening 67. The dimension of the limiting opening 68 in the height direction of the top cover 20 matches the width of the limiting protrusion 64, preferably slightly larger than the width of the limiting protrusion 64. This design facilitates the entry of the limiting protrusion 64 into the limiting opening 68 and also prevents the limiting protrusion 64 from falling out of the limiting opening 68. In actual operation, when you want to fix the top cover 20 to the side wall 6, simply align the limiting opening of the top cover 20 with the limiting protrusion 64 and insert it, and then rotate the top cover 20 to make the limiting opening 68 lock the limiting protrusion 64.

[0137] To further prevent the limiting protrusion 64 from falling out of the limiting opening, such as Figure 28 As shown, the limiting protrusion 64 is also provided with a positioning groove 69, and the extension 66 of the top cover 20 is also provided with a positioning rib 70 that cooperates with the positioning groove 69 at a position corresponding to the limiting opening. It can be understood that in other embodiments not shown, the positioning groove may also be provided on the extension, and the positioning rib may be provided on the limiting protrusion.

[0138] More preferably, the side wall portion 6 is provided with two limiting protrusions 64 that are positioned opposite to the central axis of the main body 52, and the extension portion 66 of the top cover 20 is provided with two limiting openings that correspond to the two limiting protrusions 64 respectively. This design can securely connect the top cover 20 to the side wall portion 6.

[0139] like Figure 10-12 as well as Figure 32 and 33 As shown, the stirring assembly 18 also includes a rotating shaft 33 and a connecting shaft 27 connected to the rotating shaft 33. The connecting shaft 27 is a hollow structure, and its inner surface is provided with a toothed structure extending along its height direction. The rotating shaft 33 has a first end 38 and a second end 39. The first end 38 is connected to the interior of the connecting shaft 27, and the first end 38 is provided with a toothed structure that cooperates with the toothed structure of the connecting shaft 27, so that the connecting shaft 27 can drive the rotating shaft 33 to rotate together, and the rotating shaft 33 can move up and down relative to the connecting shaft 27. The second end 39 is inserted into the connection port 55 of the stirring member 19. Preferably, the second end 39 has a shape that matches the shape of the connection port 55. In the illustrated embodiment, the cross-section of the second end 39 is square, so that the rotating shaft 33 can drive the stirring member 19 to rotate together and move up and down.

[0140] Further reference Figure 11 and Figure 12 The top cover 20 has a downwardly extending recess 35, and the connecting shaft 27 is disposed in the recess 35. The bottom of the recess 35 and the bottom of the connecting shaft 27 are respectively provided with a first through hole 36 and a second through hole 37, and the rotating shaft 33 extends through the first through hole 36 and the second through hole 37 and is connected to the inside of the connecting shaft 27.

[0141] refer to Figure 12 The top of the agitator 19 has a surface that can fit into the bottom surface of the recess 35 (fitting state as follows). Figure 11 The upper bonding surface 73 (as shown). Preferably, the radial extension distance d of the upper bonding surface 73 in the stirring member 19 is less than or equal to 5 mm. This design can prevent rice grains from remaining on the upper bonding surface 73, thus preventing the stirring member 19 from moving into place. Figure 11 The location shown.

[0142] Preferably, the washing assembly 5 further includes an elastic element 40, which may be configured as a spring. The elastic element 40 is sleeved inside the connecting shaft 27 on the rotating shaft 33, and the first end 38 of the rotating shaft 33 has a flange 41 extending radially outward along the rotating shaft 33 to restrain the elastic element 40 in a suitable position. The elastic element 40 can cause the rotating shaft 33 and the agitator 19 connected to the rotating shaft 33 to return upward, that is, from... Figure 12 Return to the location shown Figure 11 The location shown.

[0143] Driver components

[0144] In one embodiment, the cooking appliance 1 further includes a drive assembly capable of driving at least a portion of the stirring assembly 18 to rotate, thereby completing the washing and rice-spinning processes; and capable of driving at least a portion of the stirring assembly 18 together with the washing chamber cover 17 to move between an open position and a closed position, thereby completing operations such as rice feeding and drainage (described later). Furthermore, the drive assembly is also capable of driving the feeding chamber 16 to move between a first position and a second position.

[0145] The drive assembly is disposed within the storage mechanism, or at least a portion thereof is disposed within the feeding mechanism 15. In one embodiment, the drive assembly is at least partially located within the storage hopper 13, or at least partially located outside the storage hopper 13 but within the space enclosed by the storage hopper 13. In the illustrated embodiment, a portion of the drive assembly is disposed within the feeding mechanism 15. In particular, the drive assembly is not disposed on the lid 4. Because drive assemblies are typically electrically driven, this design, by disposing of the drive assembly outside the lid 4, facilitates user cleaning of the lid 4 and the washing assembly 5, ensuring safety. Furthermore, this design eliminates the need to consider waterproofing during the manufacturing stage of the lid 4, thereby simplifying the manufacturing process.

[0146] The drive assembly includes a drive shaft 26, which is engageable with a connecting shaft 27 and can drive the connecting shaft 27 to rotate. The drive shaft 26 is also engageable with a rotating shaft 33 and can drive the rotating shaft 33 to move downwards. The structure of the drive assembly will be described in detail below.

[0147] like Figure 2-7 as well as Figure 11-19 As shown, the drive assembly includes a first drive device 21 and a first transmission device connected to the first drive device 21. The first drive device 21 is disposed in the storage bin 13; for example, the first drive device 21 can be a motor. The feeding mechanism 15 is connected to the first transmission device, and the first drive device 21 drives the feeding mechanism 15 to move between a first position and a second position via the first transmission device.

[0148] In a preferred embodiment, the first transmission device includes a screw member 22 and a nut member 23 screwed onto the screw member 22. The screw member 22 is connected to the output shaft of a first drive device 21, which is capable of driving the screw member 22 to rotate in both the forward and reverse directions. When the first drive device 21 drives the screw member 22 to rotate in both directions, the nut member 23 can move up and down accordingly. The nut member 23 is connected to the outer wall of the feeding bin 16, thereby enabling the entire feeding bin 16 to move up and down between a first position and a second position.

[0149] It is understood that the feeding bin 16 can only move within the range limited by the screw member 22. Preferably, the vertical movement range of the feeding bin 16 is 0-200mm. It is also more preferably that the feeding bin 16 has at least one third position (described below) between the first position and the second position. The position of the feeding bin 16 can be controlled by setting a first position detection device 85 in the feeding mechanism 15.

[0150] The first position detection device 85 can detect the position of the feeding bin 16 in the machine body assembly 11. When the first position detection device 85 detects that the feeding bin 16 is in the first position, the second position, or the third position, it can send a signal to the first drive device 21 to stop the first drive device 21 from driving the feeding bin 16 to move.

[0151] In one embodiment, the first position detection device 85 includes a first optical coupler plate, a second optical coupler plate, and a third optical coupler plate arranged vertically at intervals. The second and third optical coupler plates can detect signal on / off information. An extension rib may be provided on the feeding bin 16. When the feeding bin 16 moves vertically until the extension rib passes through the first optical coupler plate, the first position detection device 85 determines that the feeding bin 16 has reached a first position. When the feeding bin 16 moves vertically until the extension 66 passes through the second optical coupler plate, the first position detection device 85 determines that the feeding bin 16 has reached a second position. When the feeding bin 16 moves vertically until the extension rib passes through the third optical coupler plate, the first position detection device 85 determines that the feeding bin 16 has reached a third position. It is understood that in other embodiments not shown, other suitable first position detection devices 85 may be selected, such as microswitches.

[0152] Preferably, the drive assembly further includes a second drive device 24 and a second transmission device connected to the second drive device 24. The second drive device 24 and the second transmission device are disposed in the feeding bin 16, so that both the second drive device 24 and the second transmission device can move up and down together with the feeding bin 16.

[0153] The second drive device 24 can be an electric motor. The second transmission device can be engaged with the stirring assembly 18, and the second drive device 24 is configured to drive the stirring assembly 18 to rotate via the second transmission device.

[0154] In a preferred embodiment, the second drive unit 24 may also include a gearbox 87, the output shaft of which is directly connected to the second transmission device, driving the second transmission device to rotate. In other embodiments, where the motor serving as the second drive device is infinitely variable in speed, a gearbox may not be required. The second transmission device includes a sliding shaft 25 connected to the output shaft of the second drive unit 24 and a drive shaft 26 connected to the sliding shaft 25. The second drive unit 24 can drive the sliding shaft 25 to rotate, and the sliding shaft 25 can drive the drive shaft 26 to rotate. Figure 18 As shown, one end of the drive shaft 26 has an irregular shape that mates with the sliding shaft 25, allowing the sliding shaft 25 to drive the drive shaft 26 to rotate. In the illustrated embodiment, the cross-section of this end of the drive shaft 26 is hexagonal. The other end of the drive shaft 26 has a toothed structure. When in the washing state, as... Figure 5As shown, the drive shaft 26 can engage with the connecting shaft 27 and drive the connecting shaft 27 to rotate, while the connecting shaft 27 drives the rotating shaft 33 and the stirring component 19 to rotate.

[0155] Preferably, such as Figure 13 and 14 As shown, the drive assembly also includes a third drive device 28 and a third transmission device connected to the third drive device 28. The third drive device 28 and the third transmission device are disposed in the feeding bin 16, so that both the third drive device 28 and the third transmission device can move up and down together with the feeding bin 16.

[0156] The third drive device 28 can be an electric motor. The third transmission device can be engaged with the stirring assembly 18, and the third drive device 28 can drive a part of the third transmission device to move up and down, and the third transmission device drives the stirring component 19 to move down.

[0157] Preferably, such as Figure 13-19 As shown, the third transmission device includes a first gear 29 connected to the output shaft of the third drive device 28, a second gear 30 meshing with the first gear 29, and a transmission screw 31. The third drive device 28 can drive the first gear 29 to rotate in both the forward and reverse directions, thereby allowing the second gear 30 to rotate in the corresponding directions. The second gear 30 has an inner hole 32, which is sleeved on the outside of the transmission screw 31. The inner hole 32 has an internal thread that engages with the external thread of the transmission screw 31. Thus, when the second gear 30 rotates in the two directions, the transmission screw 31 can move upward or downward as the second gear 30 rotates in either direction.

[0158] like Figure 13-15 As shown, the rice feeding mechanism also includes a gear cover 74, which is connected to the bottom of the feeding bin 16. The gear cover 74 includes a first part 79 and a second part 80 connected to the first part 79. The first part 79 is supported at the bottom of the first gear 29, and the second part 80 is supported at the bottom of the second gear 30, and has an opening for the transmission screw 31 to pass through. Preferably, the feeding bin 16 is also provided with a receiving structure that cooperates with the second gear 30, thereby limiting the second gear 30 through the receiving structure and the second part 80, so that it can only rotate and cannot move up and down.

[0159] Preferably, such as Figure 16-19As shown, the transmission screw 31 is provided with a limiting rib 75 and a positioning rib 76 protruding radially, and the feeding bin 16 is provided with a limiting groove 77 that mates with the limiting rib 75 and a hole 78 that mates with the positioning rib 76. This design restricts the transmission screw 31 to only move up and down and prevents it from rotating. Preferably, the range of vertical movement of the transmission screw 31 is 0-500mm, and the position of the transmission screw 31 can be controlled by providing a second position detection device 86 in the feeding mechanism 15. The structure and working principle of the second position detection device 86 are similar to those of the first position detection device described above, and will not be repeated here for simplicity. In one embodiment, the positioning rib 76 extends from the hole 78 to mate with the optical coupling plate of the second position detection device 86.

[0160] The transmission screw 31 is sleeved on the outside of the drive shaft 26. Preferably, the bottom of the drive shaft 26 is provided with a stepped portion 34 extending outward in the radial direction of the drive shaft 26. The transmission screw 31 is limited between the stepped portion 34 and the sliding shaft 25 above it, thereby preventing relative displacement of the transmission screw 31 and ensuring the accuracy of the movement.

[0161] pot lid

[0162] To further facilitate the removal and cleaning of pot lid 4, such as Figure 20-22 As shown, in a preferred embodiment, the pot lid 4 includes a pot lid body 42 and a detachable cover 43. The detachable cover 43 is detachably connected to the pot lid body 42, so that when the user intends to clean the detachable cover 43, it can be directly removed, which is simple and convenient. In one embodiment, the detachable cover 43 can be sleeved on the side wall portion 6 of the washing assembly 5.

[0163] In a preferred embodiment, the cooking appliance 1 further includes a drain assembly, which includes a drain pipe 10 and a wastewater tank 48 connected to the drain pipe 10 (e.g., Figure 1 (As shown). The main body 52 is also provided with a drain outlet 9, one end of which is connected to the drain outlet 9, so that wastewater in the washing chamber can be discharged. The other end of the drain outlet 10 is connected to the atmosphere via a wastewater tank 48. At least a portion of the drain outlet 10 is located in the pot lid 4. Specifically, depending on the location of the wastewater tank 48 in the cooking appliance 1, if the wastewater tank 48 is located away from the drain outlet 10 in the pot lid 4, then a portion of the drain outlet 10 may also be located in the body assembly 11. Figure 1 and 2 As shown in the preferred embodiment, the drain pipe 10 is entirely housed within the pot lid 4. The body assembly 11 also includes a receiving seat 83 adjacent to the base 12, in which the wastewater tank 48 is removably disposed, and the drain pipe 10 can be directly connected to the wastewater tank 48.

[0164] Preferably, the position of the drain pipe 10 in the height direction of the washing assembly 5 is not higher than the position of the drain outlet 9 in the height direction. For example Figure 2-7 as well as Figure 20 , Figure 24 As shown, the sewage pipe 10 is also equipped with a connecting pipe 10a extending toward the sewage tank 48. The sewage tank 48 is connected to the sewage pipe 10 via the connecting pipe 10a and is located below the sewage pipe 10. This design facilitates the flow of sewage from the washing chamber into the sewage pipe 10 and the sewage tank 48 by gravity.

[0165] According to this design, the drain pipe 10 is at least partially housed within the pot lid 4, which is removable. Therefore, when a user wishes to clean the drain pipe 10, they only need to remove the pot lid 4, making it convenient for the user.

[0166] In a preferred embodiment, at least a portion of the sewage discharge assembly is detachably or non-detachably mounted on the removable cover 43. This arrangement, by mounting at least a portion of the sewage discharge assembly on the removable cover, facilitates cleaning of the sewage discharge assembly when the cover is removed. Furthermore, by detachably mounting a portion of the sewage discharge assembly on the removable cover, it is possible to further disassemble the sewage discharge assembly for cleaning, thereby achieving a more thorough cleaning.

[0167] like Figure 21-24 As shown, the drain pipe 10 includes a support portion 44 disposed on the removable cover 43 and a covering portion 45 disposed on the lid body 42. The cross-section of the support portion 44 is approximately U-shaped, and the covering portion 45 is plate-shaped. The positions of the support portion 44 and the covering portion 45 correspond. When the removable cover 43 is connected to the lid body 42, the covering portion 45 can cover the support portion 44 to form the drain pipe 10. This design allows the upper and lower parts of the drain pipe 10 to be disassembled when the removable cover 43 is removed from the lid body 42, thereby enabling a more thorough cleaning of the drain pipe 10 and avoiding the formation of unsanitary corners. In other embodiments not shown, the support portion 44 and the covering portion 45 can also be constructed in other shapes, as long as they can cooperate to form a complete drain pipe 10. For example, the support portion 44 can be fixed to the removable cover 43 by means of a hot-melt structure, a screw structure, or a rivet structure, or the support portion 44 can be integrally formed with the removable cover 43 by sheet metal molding or secondary injection molding. In addition, the support portion 44 can also be detachably connected to the removable cover 43 by means of a snap-fit ​​structure or the like.

[0168] Preferably, such as Figure 22 and 23As shown, the drain pipe 10 also includes a sealing element 49 disposed between the support portion 44 and the cover portion 45. In the illustrated embodiment, the sealing element 49 is connected to the support portion 44, and when the removable cover 43 is connected to the pot lid body 42, the cover portion 45 can press against the sealing element 49 to form a seal.

[0169] In a preferred embodiment, the drain pipe 10 includes a first pipe 50 and a second pipe 51 communicating with the first pipe 50. The first pipe 50 is arranged in a ring around the side wall portion 6, and the second pipe 51 extends from the first pipe 50 along the radial direction of the pot lid 4 to the outer periphery of the pot lid 4. Figure 20 and 22 As shown, the inner ring portion 84 of the removable cover 43, which is connected to the side wall portion 6, is also provided with a sealing structure. The inner ring portion 84 forms part of the first pipe 50, and the inner ring portion 84 is located below the side wall portion 6 relative to the drain outlet 9.

[0170] To improve drainage efficiency, preferably, the main body 52 includes multiple drain outlets 9, all of which are disposed on the side wall portion 6 and are evenly spaced along the circumferential direction of the side wall portion 6. The drainage process will be described in detail below.

[0171] In another implementation, such as Figure 25 As shown, the main body 52 includes only one drain outlet 9' provided on the side wall portion 6. In this embodiment, the drain pipe 10' extends radially from the drain outlet 9' to the outer periphery of the lid 4 within the lid 4. That is, in this embodiment, the drain pipe 10' does not include the annular first pipe.

[0172] In one embodiment, the washing hopper cover 17, while capable of opening and closing the discharge port, can also function as a drain valve, opening or closing the drain port as needed. Specifically, the washing hopper cover 17 has a communicating position and a sealed position, such as... Figure 6 As shown, when the washing chamber cover 17 is in the connected position, the washing chamber cover 17 is located below the drain port 9 within the main body, and the drain port 9 is connected to the washing chamber. Figure 5 As shown, when the washing chamber cover 17 is in the closed position, the washing chamber cover 17 is located above the drain port 9 inside the main body, and the drain port 9 is not connected to the washing chamber. This solution can eliminate the need for a drain valve.

[0173] In one embodiment, the sewage pipe 10 can also be used as a steam exhaust pipe. For example, as... Figure 5 As shown, Figure 5 As shown, when the washing chamber cover 17 is in the closed position, the sealing part 47 is positioned above the drain port 9 within the main body 52. ​​The drain port 9 is connected to the cooking chamber, allowing steam generated in the cooking chamber to be discharged to the outside through the drain port 9 and the drain pipe 10. Figure 6 As shown, when the washing chamber cover 17 is in the connected position, the sealing part 47 is located below the drain port 9 within the main body 52, and the drain port 9 is not connected to the cooking chamber. Therefore, steam generated in the cooking chamber cannot be discharged through the drain port 9. Furthermore, the washing chamber cover 17 also has an intermediate position that partially connects the drain port 9 to the cooking chamber. The method for venting steam will be further explained later.

[0174] Return to reference Figure 1 The cooking appliance 1 also includes a water inlet assembly. The water inlet assembly includes a clean water tank 81 and a water inlet pipe 99 (such as...). Figure 15 (Shown) and a water pump (not shown). A clean water tank 81 is detachably mounted on the machine 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 clean water tank 81 can connect to the washing chamber via a water inlet pipe 99. Preferably, the water inlet pipe 99 is located in the feeding mechanism 15 and is driven by a drive assembly to connect with the washing chamber for water addition. The liquid inlet of the washing chamber can be located on the top cover 20. Preferably, the liquid inlet of the washing chamber can be the same as the feed inlet 7. When adding water, the water pump can be turned on, supplying water from the clean water tank 81 to the washing chamber through the water inlet pipe 99 in the feeding mechanism 15. The clean water tank and the wastewater tank are located on the side of the machine body opposite to the storage hopper.

[0175] In one embodiment, the cooking appliance further includes a control unit that can be coupled to a first drive device, a second drive device, a third drive device, and a water pump to control the operation of the aforementioned components.

[0176] In a preferred embodiment, all electrical components (such as motors, heating elements, and temperature sensors) in the cooking appliance are located on the main body and the pot body, leaving no electrical components in the lid. This eliminates the need for waterproofing during lid manufacturing and makes cleaning easier. When the lid is detachable from the pot body, it can be removed for separate cleaning. Since it contains no electrical components, it can be rinsed under running water or washed in a basin. Alternatively, all electrical components are located on the main body, leaving neither the lid nor the pot body with any electrical components. With no electrical components in either the lid or the pot body, waterproofing is not a concern, and both the lid and pot body can even be rinsed under running water.

[0177] The following text is for reference only. Figures 2-7 The entire working process of the cooking appliance 1 according to the preferred embodiment is described as follows:

[0178] like Figure 2 As shown, the cooking appliance 1 is in its initial state. At this time, the feeding bin 16 is in the first position, and the feeding bin 16 is not connected to the outlet 14 of the storage bin 13 or the inlet 7 of the washing assembly 5.

[0179] When the intention is to perform the feeding operation, the first drive device 21 can drive the first transmission device to operate, thereby driving the feeding bin 16 to move downwards to the second position. For example... Figure 3 As shown, the cooking appliance 1 is in the rice-feeding state. At this time, the feeding chamber 16 is in the second position, and it is connected to both the outlet 14 and inlet 7 of the storage chamber 13. When in the rice-feeding state, the inlet 88 can connect to the outlet 14 of the storage chamber 13, and the outlet 82 can connect to the inlet 7 of the washing assembly 5, so that the material in the storage chamber 13 enters the feeding chamber 16 through the inlet 88 and then enters the washing assembly 5 through the outlet 82. The amount of rice flowing into the washing chamber can be calculated over time.

[0180] After the rice feeding operation is completed or during the rice feeding operation, the control unit can control the water pump of the water inlet component to start, thereby introducing water from the clean water tank into the main body of the washing bin through the water inlet pipe 99, in preparation for the washing operation.

[0181] When the rice feeding and water dispensing operations are completed, the first drive device 21 drives the first transmission device to move, and the first transmission device drives the feeding bin 16 to move upward to the third position, as shown below. Figure 4 As shown. The third position is located between the first and second positions. In the third position, the feeding bin 16 is not connected to the outlet 14 of the storage bin 13 or the inlet 7 of the washing assembly 5. This design, by setting a third position, can allocate a portion of the vertical movement of the drive shaft 26 to the feeding bin 16, thereby reducing the travel distance of the drive shaft 26 and preventing it from becoming too long.

[0182] When you intend to perform a washing operation, such as Figure 5 , Figure 13 and Figure 14 As shown, the third drive device 28 can drive the first gear 29 to rotate, the first gear 29 drives the second gear 30 to rotate, and the second gear 30 drives the transmission screw 31 to move downward. Since the transmission screw 31 is sleeved outside the drive shaft 26, the drive shaft 26 also moves downward with the transmission screw 31 until it engages with the connecting shaft 27 of the washing assembly 5. At this time, the second drive device 24 can be opened, so that the second drive device 24 drives the drive shaft 26 to rotate, thereby the drive shaft 26 can drive the connecting shaft 27 to rotate. When the connecting shaft 27 rotates, the rotating shaft 33 engaged with the connecting shaft 27 and the agitator 19 can rotate, thereby enabling the washing operation. The washing chamber contains material and water, which are stirred together by the agitator 19. It can be understood that during the washing operation, the washing chamber cover 17 is located above the drain port 9.

[0183] When the washing operation is complete and drainage is desired, the third drive device 28 can be activated to drive the transmission screw 31 downwards. The transmission screw 31 pushes the rotating shaft 33 downwards, thereby causing the agitator 19 to move downwards. When the agitator 19 moves down to the position below the drain port 9 on the washing hopper cover 17, i.e., the connection position, ... Figure 6 As shown, the third drive device 28 is stopped, and the wastewater in the washing chamber can flow through the drain port 9 to the drain pipe 10 and the wastewater tank 48. It is understood that in other embodiments, drainage can also be performed during the washing operation, that is, drainage can be performed while washing, and water can also be added during the washing operation.

[0184] When drainage is complete and the rice feeding operation is about to begin, the third drive device 28 can be activated to drive the transmission screw 31 to continue moving downwards. The transmission screw 31 pushes the rotating shaft 33 downwards, thereby allowing the agitator 19 to move downwards and leave the washing chamber. Figure 7 As shown. When the stirring element 19 moves down to leave the washing chamber, the third drive device 28 is stopped and the second drive device 24 is opened, so that the stirring element 19 can be driven to rotate and throw the washed rice into the inner pot 3.

[0185] After the rice is thrown into the inner pot, or at the same time as the rice is thrown into the inner pot, the control unit can control the water pump of the water inlet component to turn on, so that the water in the clean water tank is introduced into the washing chamber through the water inlet pipe 99 and flows into the inner pot through the washing chamber to prepare for cooking.

[0186] After the rice feeding operation is completed, the third drive device 28 can drive the transmission screw 31 to move upward. After the transmission screw 31 moves upward into the feeding hopper 16, the first drive device 21 can drive the feeding hopper 16 back to the first position. At this time, the rotating shaft 33 and the stirring component 19 connected to it can return to their original positions upward through the elastic element 40.

[0187] The following explains the methods for controlling steam during cooking:

[0188] In one embodiment, during the cooking process, when it is desired to vent steam from the cooking chamber, the washing chamber cover 17 can be in a sealed position, allowing the steam in the cooking chamber to escape through the drain port 9. This stage can be, for example, a water absorption stage, a heating stage, a boiling stage, or a heat preservation stage. The washing chamber cover 17 being in a sealed position can be as follows: Figure 2 The position shown is when the cooking appliance is in its initial state.

[0189] Preferably, the position of the washing chamber cover 17 can be adjusted as needed during the cooking process, so that the portion of the drain outlet 9 communicating with the cooking chamber is variable, that is, the size of the connection between the drain outlet 9 and the cooking chamber can be adjusted. In one embodiment, the position of the washing chamber cover 17 can be adjusted so that only a portion of the drain outlet 9 communicates with the cooking chamber. This can be implemented, for example, when it is desired to maintain a slight pressure in the cooking chamber, so that not all the steam in the cooking chamber is discharged, but some remains in the cooking chamber, thereby maintaining a slight pressure in the cooking chamber. In another embodiment, the position of the washing chamber cover 17 can be adjusted in the later stages of the cooking process to increase the portion of the drain outlet 9 communicating with the cooking chamber, for example, increasing the portion of the drain outlet 9 communicating with the cooking chamber in stages such as the heat preservation stage or the exhaust stage, or making the entire drain outlet 9 communicate with the cooking chamber, thereby accelerating the exhaust speed.

[0190] In one embodiment, the washing chamber cover 17 can also be controlled to be in the open position during at least one stage of the cooking process, so that the cooking chamber is kept under pressure. For example, the washing chamber cover 17 can be kept in the closed position during the pressure maintenance stage after boiling. It is understood that this process is the rice cooking process other than the washing process.

[0191] In one embodiment, the drain pipe 10 can also be cleaned. Before and / or after the cooking process, the user can manually add water to the cooking chamber or add water through the water tank 81, and keep the washing chamber cover 17 in a sealed position. Then, the heating device is controlled to heat the water in the cooking chamber, so that the generated steam flows through the drain port 9 to the drain pipe 10 to purify the drain pipe 10.

[0192] In one embodiment, steam in the cooking chamber can also be discharged through the main body 52 during cooking. For example, when it is desired to discharge steam from the cooking chamber, the washing chamber cover 17 can be moved to the open position, such as... Figure 7 As shown, at this time, part of the steam in the cooking chamber can be discharged through the drain port 9, and the other part can be discharged through the main body 52, especially through the feed port 7 on the top cover 20.

[0193] According to this embodiment, the inner pot 3, pot lid 4, washing assembly 5, clean water tank 81, and waste water tank 48 of the cooking utensil 1 can all be easily removed for washing, simplifying the entire cleaning process of the cooking utensil 1.
