[0141] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0142] To fully understand this application, a detailed description will be provided in the following description. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other embodiments.

[0143] The ordinal numbers such as “first” and “second” used in this application are merely identifiers and have no other meaning, such as a specific order. Furthermore, for example, the term “first component” does not imply the existence of a “second component,” and the term “second component” does not imply the existence of a “first component.” The use of words such as “first,” “second,” and “third” does not indicate any order and can be interpreted as names.

[0144] It should be noted that the terms “upper,” “lower,” “front,” “back,” “left,” “right,” “inner,” “outer,” and similar expressions used in this application are for illustrative purposes only and are not intended to be limiting.

[0145] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0146] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0147] This application provides a cooking device. Specifically, it is an automated cooking device capable of automatically adding rice and water and completing the cooking process.

[0148] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0149] like Figures 1 to 3 As shown, in a specific embodiment, the cooking equipment 100 according to this application includes a cooking appliance 10, a storage container 11, a clean water tank 73, and a wastewater tank 74. The cooking appliance 10 is used to perform cooking functions, such as cooking rice or porridge. The storage container 11 is used to store solid food materials, such as rice, beans, and other grains. The storage container 11 can employ temperature and humidity control measures to preserve the food. The clean water tank 73 stores clean water for cooking and washing. The wastewater tank 74 stores wastewater after washing.

[0150] Specifically, the cooking utensil 10 includes, for example, a pot body 22 and a lid 21. The pot body 22 is used to heat solid food ingredients, and the lid 21 is used to close the pot body 22. A removable inner pot 26 is disposed within the pot body 22, and the internal space of the inner pot 26 forms a cooking cavity 27 for holding food ingredients. A heating device 28 is also provided in the pot body 22, for example, located below the inner pot 26, to heat the inner pot 26 and cook the food. The lid 21 is pivotally connected to the pot body 22 at the rear, for example, allowing the front of the lid 21 to rotate upwards to open the pot body 22, which is convenient for user operation. Of course, the lid 21 can also be moved relative to the pot body 22 in other ways to open and close the pot body 22.

[0151] It should be noted that the directional terms "up," "down," "front," "back," "left," and "right" used in this article are based on the orientation determined when the cooking device 100 is placed upright, facing the user in its normal use state, and the lid 21 is in the closed state. Specifically, the orientation of the cooking device 100 facing the user is defined as "front," and the opposite orientation is defined as "back."

[0152] To facilitate the placement and removal of the inner pot 26, a washing chamber 24 is located within the lid 21. The internal space of the washing chamber 24 forms a washing cavity 25 for cleaning solid materials. A washing device 23 is typically installed in the washing chamber 24. When the lid 21 closes the pot body 22, the cooking device 100 can control the connection between the washing cavity 25 and the cooking cavity 27.

[0153] The washing chamber 25 is connected to the clean water tank 73 via a clean water pipe (not shown). Clean water from the clean water tank 73 is supplied to the washing chamber 25 via the clean water pipe using a water supply device (e.g., a water pump). The washing chamber 25 is connected to the wastewater tank 74 via a drain pipe 79, thereby discharging the wastewater after washing into the wastewater tank 74 via the drain pipe 79.

[0154] The storage container 11 includes a storage bin 14 for storing solid food materials, and the internal space of the storage bin 14 is a storage chamber 15. The storage chamber 15 is connected to the washing chamber 25 via a feeding pipe. The cooking equipment 100 also includes, for example, a feeding device (not shown) for feeding the solid food materials in the storage chamber 15 into the washing chamber 25 via the feeding pipe. The feeding device may be configured as an airflow generator (e.g., a fan) to transfer the materials using air pressure.

[0155] Understandably, the cooking equipment 100 includes a control device, and the electrical control components of the cooking equipment 100 (such as the heating device 28, water pump, fan, etc.) all operate under the control of the control device.

[0156] The workflow of cooking equipment 100 typically includes the following steps:

[0157] Step 1: Adding ingredients. The cooking equipment 100 uses the adding device and feeding pipe to transport a certain amount of ingredients from the storage chamber 15 to the washing chamber 25, and then stops the adding device.

[0158] The second step is washing the ingredients. The water pump is controlled to add a certain amount of clean water to the washing chamber 25, and then the washing device 23 in the washing chamber 25 is driven to work (e.g., rotate) to wash the ingredients.

[0159] Step 3: Drainage. After the washing process is completed, the washing device 23 is stopped, and the wastewater is discharged from the drain pipe 79 into the sewage tank 74.

[0160] Step 4: Discharge. After washing and draining, connect the washing chamber 25 to the cooking chamber 27, allowing the ingredients in the washing chamber 25 to fall into the cooking chamber 27 by their own weight.

[0161] Because the washing chamber 25 has a limited volume, the control device calculates the number of feeding cycles based on the amount of food set by the user, and repeats steps one to four above until the amount of food in the cooking chamber 27 reaches the user's required amount. When using an exhaust device for feeding, under stable airflow conditions, the amount of food fed is basically proportional to the exhaust time.

[0162] Step 5: Add water. Based on the cooking function set by the user, calculate the amount of water needed for cooking and control the water adding device to add water to the cooking chamber 27 through the washing chamber 25.

[0163] Step 6: Cooking. Control the heating device 28 according to the cooking program to complete the cooking process.

[0164] Understandably, all of the above steps are performed when the lid 21 closes the pot body 22.

[0165] In this application, both the washing chamber 25 and the cooking chamber 27 are places for processing solid food materials, or in other words, for completing cooking-related processes using solid food materials, and are also referred to as processing chambers. The processing chamber provided in the cover 21 can also be used to perform other food processing functions, such as crushing, pretreatment, etc. More broadly, the washing chamber 25 is also a container for at least temporarily holding food materials, and correspondingly, the washing bin 24 is a container for at least temporarily holding food materials. The container can be used to process food materials, that is, used as a processing bin; or it can be used only for temporarily storing food materials, that is, used as a transfer bin. In the illustrated embodiment, the cooking device 100 is described as an example of a washing bin for washing food materials. However, the container can also be used for other functions.

[0166] like Figure 3 As shown, the feeding conduit includes a first conduit assembly 30 located in the storage container 11 and a second conduit assembly 40 located in the cooking appliance 10. The second conduit assembly 40 is disposed in the cover 21 to facilitate connection with the washing chamber 25 in the cover 21. Each of the conduit assemblies 30 and 40 provides at least one conduit segment, each segment having openings at both ends connected by internal channels (cavities), all of which form the feeding conduit.

[0167] The first pipe assembly 30 includes a first end 31 and a second end 32 disposed opposite to each other. The first end 31 of the first pipe assembly is used to communicate with the storage chamber 15 (e.g., to communicate with the outlet 15A of the storage chamber 15), and the second end 32 of the first pipe assembly is used to connect with the second pipe assembly 40. The second pipe assembly 40 includes a first end 41 and a second end 42 disposed opposite to each other. The first end 41 of the second pipe assembly is used to connect with the second end 32 of the first pipe assembly, and the second end 42 of the second pipe assembly is used to communicate with a processing chamber (e.g., a washing chamber 25) (e.g., an opening in the processing chamber).

[0168] The pipe assemblies 30 and 40 together form a feeding pipe, the internal channels of which allow solid food materials to pass through. Preferably, the cross-sectional area of ​​the feeding channel is 40 mm². 2 Up to 800mm 2 In other words, the cross-sectional area of ​​the channel through which the solid material passes in the first conduit assembly 30 is 40 mm. 2 Up to 800mm 2 The cross-sectional area of ​​the channel for passing solid material in the second pipe assembly 40 is 40 mm. 2 Up to 800mm 2 The inner diameter of the feeding channel can be consistent or inconsistent (e.g., depending on space constraints). The cross-sectional shape of the feeding channel can be circular, square, elliptical, polygonal, etc.

[0169] When the feeding device is configured as an air extraction device, the air extraction device is used to extract air from the opening at the second end 42 of the second pipe assembly, for example, from the washing chamber 25, or from the air outlet duct 80 connected to the washing chamber 25. Of course, the cooking equipment 100 can also use other methods to feed the ingredients.

[0170] To save on piping, the cooking appliance 10 and the storage container 11 are arranged adjacent to each other, for example, they are arranged adjacent to each other along a first direction D1. The first direction D1 is a horizontal direction, such as a left-right direction. Furthermore, to facilitate pipe connection, the second end 32 of the first pipe assembly opens into the side of the storage container 11 facing the cooking appliance 10. Figure 2 As shown, the outer casing 18 of the storage container has a first opening 13 on the side facing the cooking appliance 10. The second end 32 of the first pipe assembly opens into the first opening 13, allowing it to connect to the second pipe assembly 40. Furthermore, the storage compartment 14 is located inside the storage container 11 on the side away from the cooking appliance 10, while the first pipe assembly 30 is located inside the storage container 11 on the side closer to the cooking appliance 10, minimizing the length of the first pipe assembly 30. Similarly, the first end 41 of the second pipe assembly opens into the cooking appliance 10 on the side facing the storage container 11.

[0171] like Figure 4 As shown, the cooking device 100 is provided with an air inlet 19. Specifically, the storage container 11 is also provided with a first cavity 16, and the outlet 15A of the storage cavity 15 and the opening of the first end 31 of the first pipe assembly are both connected to the first cavity 16. The cavity wall of the first cavity 16 is provided with an air inlet 19 to allow the first cavity 16 to communicate with the environment. Thus, the air inlet 19 and the air extraction device are located at opposite ends of the feeding channel. When the air extraction device is working, the airflow in the feeding channel flows in one direction, ensuring the unidirectional flow of the food ingredients, which helps to improve the feeding efficiency.

[0172] The air inlet 19 is sized to prevent solid food materials from passing through. The air inlet 19 can be square, round, elliptical, polygonal, etc. Typically, the size of the air inlet 19 is no greater than 3mm, thus preventing most common solid food materials from leaking out. The total area of ​​all air inlets 19 is 30% to 300% of the cross-sectional area of ​​the feeding channel through which solid food materials pass. In other words, the total area of ​​all air inlets 19 is 30% to 300% of the cross-sectional area of ​​the feeding channel at any point in the first pipe assembly 30 and the second pipe assembly 40.

[0173] For example, the discharge port 15A is located at the bottom of the storage chamber 15, allowing food to enter the first chamber 16 by gravity. To maximize the volume of the storage chamber 15, it occupies almost the entire height of the storage container 11. Therefore, the first chamber 16 is located at the bottom of the storage container 11. For connection to the higher-positioned cover 21, the first pipe assembly 40 extends generally vertically. The first end 31 of the first pipe assembly extends vertically, and the first chamber 16 is located below the first end 31 of the first pipe assembly. Preferably, the air inlet 19 is located on the bottom wall 16A of the first chamber 16. Preferably, the chamber wall 17 of the storage chamber 15 at the discharge port 15A extends towards the bottom wall 16A of the first chamber 16 to guide solid material to the bottom wall 16A of the first chamber 16. The chamber wall 17 is also called the guide chamber wall. The angle α between the guide chamber wall 17 and the horizontal plane is between 10 and 90 degrees.

[0174] like Figure 5 As shown, to reduce the volume of the cover 21, the second pipe assembly 40 extends as horizontally as possible. Understandably, since the cover 21 is openable and closable, there is a connection issue between the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly; that is, there is a connection issue between the first opening 33 of the second end 32 of the first pipe assembly and the second opening 43 of the first end 41 of the second pipe assembly. Preferably, at least one of the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly has a flexible element 71 at the opening for connection, so that the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly are in sealed contact during connection. The flexible element 71 is, for example, a sealing ring, a silicone gasket, etc.

[0175] like Figure 6As shown, the second end 32 of the first pipe assembly has an annular contact plane 36 around the opening 33 for docking. The annular contact plane 36 contacts the circumference of the opening of the first end 41 of the second pipe assembly for docking. The annular contact plane 36 can be understood as a radially outward flange at the docking port, widening the pipe wall thickness at the pipe interface. The difference d (width of the ring) between the inner and outer diameters of the annular contact plane 36 is not less than 1 mm, preferably not less than 2 mm. Therefore, even if there is a positional error between the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly during docking, the annular contact plane 36 can ensure a seamless docking. In other words, the annular contact plane 36 allows for a radial positional error of no more than 1 mm between the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly during docking.

[0176] Of course, the annular contact plane 36 can also be provided around the second opening 43 for docking at the first end 41 of the second pipe assembly, or both ends of the docking can be provided with annular contact planes 36. When both ends of the docking are provided with annular contact planes 36, the two annular contact planes 36 can be directly attached. Compared with the grain material inside the pipe, direct attachment of the planes can achieve good sealing, and the flexible component 71 can be completely omitted.

[0177] In this application, the storage container 11 and the pot body 22 can be considered as the first part of the cooking device 100, and the lid 21 can be considered as the second part of the cooking device 100. The second part is movable relative to the first part. For example, the second part is rotatable relative to the first part. The second part is movable between a first position and a second position relative to the first part. When the second part is in the first position, the lid 21 closes the pot body 22. When the second part is in the second position, the lid 21 opens the pot body 22. In this application, the connection between the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly is based on the case where the lid 21 closes the pot body 22, that is, based on the case where the second part is in the first position. Specifically, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly can be connected simultaneously when the lid 21 closes the pot body 22. Alternatively, when the lid 21 closes the pot body 22, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly have not yet been connected. With the lid 21 closed on the pot body 22, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly move relative to each other to connect. The closing and connection are completed in steps, which can disconnect the feeding channel when the lid is closed, thereby preventing water in the washing chamber 25 from entering the storage container 11 and affecting the freshness of the food.

[0178] When the lid 21 closes the pot body 22, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly can move relative to each other, allowing them to be in a docking state and a separated state. In the docking state, solid material in the storage chamber 15 can enter the processing chamber through the first pipe assembly 30 and the second pipe assembly 40 under the action of the feeding device. In this application, the relative movement of the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly can be achieved by one of them moving while the other remains stationary, or by both of them being movable. Figure 7 and Figure 8 As shown, the relative movement between the two can be relative movement along the radial direction of the pipes at the docking point (the two are offset from each other or aligned); or as... Figures 9 to 11 As shown, it can also be relative movement along the axial direction of the pipes at the docking point (the two move away from or towards each other); or it can be other forms of relative movement.

[0179] Preferably, the annular contact plane 36 is located on the end face (the outermost end face in the axial direction) of the pipe assembly (e.g., the first pipe assembly 30) it surrounds, to accommodate various mating methods between the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly.

[0180] Preferably, at different positions in the circumference, the difference d between the inner and outer diameters of the annular contact plane 36 remains substantially constant, for example, not exceeding 10%, such as 100 μm. An annular shape of equal width is beneficial for accommodating errors in all radial directions.

[0181] Preferably, the annular shape of the annular contact plane 36 conforms to the contour shape of the opening of the pipe assembly it surrounds, thereby better accommodating radial positional errors. The annular shape of the annular contact plane 36 can be a circular ring, an elliptical ring, a triangular ring, a rectangular ring, a polygonal ring, etc. It is understood that the width of the annular contact plane 36 does not need to be greater than the radial dimension of the opening to be mated. Typically, the first opening 33 and the second opening 43 are constructed as identical openings, therefore the width of the annular contact plane 36 does not need to be greater than the radial dimension of the opening it surrounds. For example, when the ring is a circular ring, the difference between the inner and outer diameters of the ring is less than the inner diameter r of the opening (see...). Figure 11 When the ring is not circular, the difference between its inner and outer diameters is less than the minimum radial dimension of the opening. For example, if the opening is in the positive direction, the minimum radial dimension of the opening is the side length of the square.

[0182] The annular contact plane 36 may be perpendicular or not perpendicular to the axial direction of the second end 32 of the first pipe assembly. The annular contact plane 36 may be perpendicular or not perpendicular to the axial direction of the first end 41 of the second pipe assembly, so that the relative orientation (e.g., angle) between the second end 32 and the first end 41 of the first pipe assembly can be flexibly designed according to specific needs.

[0183] The cooking device 100 is configured such that, when the second part of the device is in the first position (when the lid 21 covers the pot body 22), the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly have not yet been fully connected, and the first opening 33 of the second end 32 of the first pipe assembly and the second opening 43 of the first end 41 of the second pipe assembly are centered or substantially centered. Then, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly can move relative to each other along the axial direction of the openings, so that the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly are connected.

[0184] Since the cooking appliance 10 and the storage container 11 are arranged along the first direction D1, preferably, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly can move relative to each other along the first direction D1, that is, the first direction D1 is the axial direction of the pipe at the interface. When the lid 21 covers the pot body 22, the axis of the first opening 33 of the second end 32 of the first pipe assembly for docking and the axis of the second opening 43 of the first end 41 of the second pipe assembly for docking both extend along the first direction D1. The two axes are designed to be collinear, but due to processing errors, installation errors, and the movement of the lid 21, the two axes may have a slight positional offset. Preferably, the cooking device 100 is constructed such that the second end 32 of the first pipe assembly is movable relative to the storage cavity 15 along the first direction D1, while the first end 41 of the second pipe assembly remains stationary.

[0185] Specifically, such as Figure 5 and Figures 9 to 11 As shown, the first pipe assembly 40 consists of a first end 31 and a second end 32. The first end 31 is configured as a first pipe (also called the first pipe 31), and the second end 32 is configured as a movable joint (also called the movable joint 32). Both the first pipe 31 and the movable joint 32 are pipe segments with oppositely arranged ends. Each pipe segment has openings at both ends, and the openings at both ends are connected by an internal channel, which is part of a feeding channel.

[0186] The first end 37 of the movable joint 32 is used to connect to the first pipe 31, and the second end 38 of the movable joint 32 is used to mate with the first end 41 of the second pipe assembly. The movable joint 32 is in the mating position relative to the storage chamber 15 (e.g., Figure 9(as shown) and separation location (e.g.) Figure 10 and Figure 11 The movable joint 32 is movable relative to the storage chamber 15 along the first direction D1 between a mating position and a separating position. When the movable joint 32 is in the mating position, the first end 37 of the movable joint is connected to the first pipe 31, and the second end 38 of the movable joint is aligned with the first end 41 of the second pipe assembly. When the movable joint 32 is in the separating position, the second end 38 of the movable joint is separated from the first end 41 of the second pipe assembly.

[0187] In the illustrated embodiment, the movable joint 32 is a bent pipe section that turns from a vertical pipe to a horizontal pipe. The vertical first end 37 is movable relative to the first pipe 31 in the radial direction of the pipe. The horizontal second end 38 is movable relative to the second pipe assembly 40 in the axial direction of the pipe.

[0188] The moving joint 32 moves a distance of, for example, 1 mm to 20 mm along the first direction D1, that is, the distance between the mating position and the separation position along the first direction D1 is 1 mm to 20 mm. This also ensures that, in the separated state, the distance between the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly along the axial direction of the pipe at the mating point is 1 mm to 20 mm. This moving distance ensures that the two pipe sections are fully separated without taking up too much space.

[0189] To ensure stable movement of the movable joint 32, a first guide assembly may be provided in the storage device 11. The first guide assembly extends along a first direction D1 and is connected to the movable joint 32 to guide its movement along the first direction D1. The first guide assembly may be, for example, a guide rod extending along the first direction D1. Figure 6 As shown, the movable joint 32 is provided with a guide hole 39, and the guide rod of the first guide assembly extends through the guide hole 39, so that the movable joint 32 can move along the guide rod.

[0190] like Figure 12 and Figure 13 As shown, the storage container 11 is provided with an actuating component 50 for driving the movable joint 32 to move along the first direction D1. The actuating component 50 is used to drive the movable joint 32 to move from the docking position to the separating position along the first direction D1. The storage container 11 is also provided with a return component (not shown), which is used to drive the movable joint 32 to move from the separating position to the docking position along the first direction D1.

[0191] Specifically, the functional component 50 includes a blocking element 51 (such as...). Figure 14As shown), the blocking member 51 is used to contact the movable connector 32, that is, it directly interacts with the movable connector 32. The blocking member 51 is in the blocking position relative to the storage cavity 15 (e.g., Figure 13 (as shown) and open positions (such as) Figure 12 The movable joint 32 is movable between (as shown). When the blocking member 51 is in the open position, the return member brings the movable joint 32 into the mating position, and the blocking member 51 in the open position at least partially opens the first opening 33 of the second end 38 of the movable joint (as shown). Figure 15 (As shown). When the blocking member 51 is in the blocking position, the blocking member 51 causes the movable joint 32 to be in the disengaged position, and the blocking member 51 blocks the first opening 33 of the second end 38 of the movable joint (as shown). Figure 16 (As shown). When the shielding member 51 blocks the first opening 33, the first pipe assembly 30 is isolated from the second pipe assembly 40. Therefore, the shielding member 51 has both a driving function and an isolation function, thus fulfilling a dual function.

[0192] For example, the blocking member 51 is movable relative to the storage cavity 15 along a second direction D2 between a blocked position and an open position. The second direction D2 is, for example, a vertical direction. To better achieve the driving of the movable joint 32 by the blocking member 51, at least one of the portion of the blocking member 51 for contacting the movable joint 32 and the portion of the movable joint 32 for contacting the blocking member 51 includes an inclined action surface, which is inclined relative to both the first direction D1 and the second direction D2. When the blocking member 51 moves along the second direction D2, the inclined action surface causes the movable joint 32 to move along the first direction D1 because the two interact through the inclined action surface that is inclined relative to both the first direction D1 and the second direction D2.

[0193] Specifically, such as Figure 6 As shown, at least one of the two outer sides of the pipe wall of the movable joint 32, spaced apart along the third direction D3, is provided with a contact portion 35; that is, at least one of the two sides of the first opening 33, spaced apart along the third direction D3, is provided with a contact portion 35. The first direction D1, the second direction D2, and the third direction D3 are three different directions. Preferably, the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. In the illustrated embodiment, both outer sides of the pipe wall of the movable joint 32, spaced apart along the third direction D3, are provided with contact portions 35. Figure 14As shown, the shielding member 51 includes a shielding portion 56 and at least one protruding rib 55. The shielding portion 56 is, for example, plate-shaped and movable along a second direction D2 between a shielded position and an open position, for shielding the first opening 33 of the second end 38 of the movable joint. The protruding rib 55 is provided on at least one of two spaced-apart sides of the shielding portion 56 along a third direction D3. The protruding rib 55 protrudes toward the movable joint 32 along a first direction D1. The protruding rib 55 is correspondingly provided with a contact portion 35 and is used to contact the corresponding contact portion 35. In the illustrated embodiment, at least one of the protruding rib 55 and the contact portion 35 includes an inclined working surface that is inclined relative to both the first direction D1 and the second direction D2. In the illustrated embodiment, the contact portion 35 includes an inclined working surface 35A that is inclined relative to both the first direction D1 and the second direction D2.

[0194] like Figure 15 and Figure 16 As shown, the actuating component 50 further includes a first driving device 52 for providing a driving force to move the blocking member 51. The actuating component 50 may also include a first transmission device 53 for connecting the first driving device 52 and the blocking member 51. The first transmission device 53 includes, for example, a matching lead screw (or threaded rod) 54 and a lead screw nut 57. The lead screw 54 extends along a second direction D2, and its outer peripheral surface is threaded. The lead screw nut 57 is screwed onto the lead screw 54 and connected to the blocking member 51, for example, to a rib 55. The first driving device 52 is configured as a motor for driving the lead screw 54 to rotate. When the motor drives the lead screw 54 to rotate, the lead screw nut 57, under the action of the limiting structure, cannot rotate with the lead screw 54, but can only move along the lead screw 54, thereby causing the blocking member 51 to move along the second direction D2. The motor can drive the lead screw 54 to rotate in either the forward or reverse direction, thereby allowing the blocking member 51 to move upward or downward.

[0195] Similar to the first guide assembly, the storage device 11 may also include a second guide assembly extending along the second direction D2. The second guide assembly is connected to the blocking member 51 and guides the blocking member 51 to move along the second direction. For example, the second guide assembly may be a guide groove extending along the second direction D2 in the storage device 11. The blocking member 51 has guide rails 59 extending along the second direction D2 on both sides opposite to the third direction D3. The guide rails 59 are accommodated in the guide groove and can move along the guide groove, thus allowing stable movement along the second direction D2. The second guide assembly ensures that the blocking member 51 can only move along the second direction D2. Simultaneously, the blocking member 51 is connected to the lead screw nut 57, thus becoming a limiting structure that restricts the rotation of the lead screw nut 57. The blocking member 51 can be integrally formed with the lead screw nut 57, for example, by injection molding into a single part.

[0196] In some embodiments not shown in this application, the second direction D2 is the vertical direction, the blocking member 51 is made of ferromagnetic material, and the first driving device 52 is an electromagnet located above the blocking member 51. When the electromagnet is energized, it attracts the blocking member 51 to move upward. When the electromagnet is de-energized, the blocking member 51 falls under its own weight. This design can omit the transmission device. In such a design, preferably, the open position is located at the top, and the blocking position is located at the bottom. That is, when feeding is required, the electromagnet is energized, opening the port of the first pipe assembly 30, and the pipe assemblies 30 and 40 are connected. After feeding is completed, and when the cooking appliance 10 is not in use, the electromagnet can be de-energized, and the blocking member 51 is in the blocking position under its own weight, protecting the food in the storage container 11.

[0197] The return member for returning the movable joint 32 to the docking position can be an elastic element, such as a spring, disposed in the storage container 11 and connected to the movable joint 32. For example, the return member can be configured as a compression spring located on the side of the movable joint 32 facing away from the second pipe assembly 40, or the return member can be configured as a tension spring located on the side of the movable joint 32 facing the second pipe assembly 40. Alternatively, the return member can include a first magnet and a second magnet that attract each other magnetically, with the first magnet disposed on the movable joint 32 and the second magnet disposed on the second pipe assembly 40 (e.g., the first end 41 of the second pipe assembly) or the cooking appliance 10 (e.g., the lid 21).

[0198] exist Figure 12 and Figure 13 In the illustrated embodiment, when the movable connector 32 is in the separated position, the first opening 13 and the first opening 33 are opposite each other along the first direction D1, and the blocking member 51 is located between the movable connector 32 and the first opening 13. When the blocking member 51 is in the open position, the blocking member 51 completely opens the first opening 33 to completely move out of the moving path of the movable connector 32, thereby not affecting the docking of the movable connector 32 and the second pipe assembly 40. When the blocking member 51 is in the blocked position, the movable connector 32 is completely retracted into the storage container 11, and the first opening 33 is completely blocked by the blocking member 51, which can effectively prevent foreign objects from entering the first pipe assembly 30 from the first opening 33.

[0199] contrast Figure 1 , Figure 12 and Figure 13To facilitate the connection between the shielding member 51 and the driving component, the shielding member 51 is located inside the housing 18 of the storage container. When the shielding member 51 is in the shielding position, the shielding part 56 also shields the first opening 13 from the inside. When the shielding member 51 is in the open position, the shielding part 56 also opens the first opening 13. Therefore, the shielding member 51 is used to both shield and open the first opening 13. Preferably, the side of the shielding part 56 opposite to the rib 55 is always in contact with the inner surface of the housing 18 of the storage container, so that the shielding part 56 can tightly shield the first opening 13 and prevent foreign objects from entering the interior of the storage container 11 through the first opening 13.

[0200] Preferably, the cooking device 100 is configured such that, after the feeding step is completed, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly are separated, and then water is added to the processing chamber (washing chamber 25 or cooking chamber 27). Preferably, the cooking device 100 is configured such that, during at least one of the water inlet period, washing period, and drainage (sewage discharge) period of the washing chamber 25, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly are separated. Preferably, the cooking device 100 is configured such that, during the entire water inlet, washing, and drainage periods of the washing chamber 25, the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly are separated. Preferably, the cooking device 100 is configured such that, after the feeding step is completed, the first pipe assembly 30 and the second pipe assembly 40 are in a separated state, and then the steps of adding water to the washing chamber 25, washing, and discharging sewage from the washing chamber 25 are performed. Preferably, the cooking device 100 is configured such that, while the first pipe assembly 30 and the second pipe assembly 40 are in a separated state, the cooking function is performed. Preferably, the cooking device 100 is configured such that after the last feeding step is completed, even if the first pipe assembly 30 and the second pipe assembly 40 are in a separated state, the first pipe assembly 30 and the second pipe assembly 40 will be connected again when the next cooking requires feeding. Thus, during the processes of adding water to the washing chamber 25, washing materials, discharging wastewater from the washing chamber 25, adding water to the cooking chamber 27, and cooking, the feeding pipe is in a disconnected state, and the opening 33 of the first pipe assembly 30 is closed.

[0201] Understandably, when the second end 32 of the first pipe assembly and the first end 41 of the second pipe assembly move relative to each other in the axial direction, in the mating state, one end can extend into the other end (the first opening 33 and the second opening 34 have different diameters). In this case, the annular contact plane 36 may not be located at the axial end face. For example, at the end with the smaller opening diameter, the annular contact plane 36 may be a certain distance away from the axial end face.

[0202] exist Figure 17In the illustrated embodiment, the second end 32 of the first pipe assembly opens onto the upper surface of the pot body 22, and the first end 41 of the second pipe assembly opens onto the lower surface of the lid 21. When the lid 21 closes the pot body 22, the two pipe sections are joined vertically. In this embodiment, to prevent water in the washing chamber 24 from entering the storage container 11, the two pipe sections can move relative to each other in the radial direction of the interface when the lid 21 closes the pot body 22. In this embodiment, the feeding pipes are joined inside the cooking appliance 10, preventing rice, water, etc., from spilling onto the outside of the cooking appliance 100, thus helping to keep the exterior of the cooking appliance 100 clean.

[0203] This application compensates for gaps caused by positional errors by increasing the thickness of the pipe wall at the pipe joint, thus achieving a good connection.
