Description

Technical Field

[0001] This invention belongs to the technical field of food processing equipment, and more specifically, relates to a cleaning device and a cooking utensil. Background Technology

[0002] In related technologies, rice cookers have an automatic rice washing function. The rice washing process is usually completed inside the rice cooker's container, and the wastewater after washing is drained away through the drainage structure on the container.

[0003] Setting up a drainage structure on the container not only makes the container's structure more complex, but also makes the drainage structure susceptible to damage from high temperatures during the heating process. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, a first aspect of the present invention provides a cleaning device, comprising: a main body having a connected inlet and a washing chamber, and a connected discharge chamber and a discharge outlet; a frame having a connected inner cavity and a drain outlet, wherein when the frame is located in the washing chamber, the inlet communicates with the inner cavity, and when the frame is located in the discharge chamber, the discharge outlet communicates with the inner cavity; and a drive assembly disposed in the main body for driving the frame to move between the washing chamber and the discharge chamber.

[0006] The cleaning device provided by this invention features a frame that can move relative to the main body. When cleaning food is required, the frame is located in the washing chamber, where the food and water to be cleaned enter. After cleaning, the frame is located in the discharging chamber, where the cleaned food is discharged. Specifically, the food and water to be cleaned enter the inner cavity of the frame through the inlet. The food is cleaned within the inner cavity using various methods, such as agitation by an agitator or vibration by a vibrator. After cleaning, the wastewater in the washing chamber is discharged through the drain, leaving the cleaned food in the inner cavity. The drive assembly can then move the frame to the discharging chamber. During this movement, the frame moves the food in the inner cavity along with the frame, allowing both to enter the discharging chamber. The inner cavity is connected to the discharging port, through which the food is discharged. The cleaned food can then be placed into the container of a cooking appliance, thus completing the discharging function. When the frame is located inside the washing chamber, its bottom contacts the bottom wall of the chamber, preventing food and water from easily flowing out. As the frame moves, its side walls push the food into the dispensing chamber. By using a movable frame, the functions of washing and dispensing food are achieved when the frame is in different chambers, eliminating the need to wash the food inside the container. This simplifies the container's structure and reduces its processing difficulty. Furthermore, separating the washing device from the container reduces the risk of damage from high temperatures when the container is heated, thus improving the functional stability of the cooking appliance equipped with this washing device.

[0007] By setting a washing chamber and a discharging chamber on the main body, the cleaning device can complete the functions of washing and discharging at the same time, eliminating the need for two separate components. This simplifies the product structure, reduces the volume occupied by the cleaning device, and consequently reduces the space occupied by the cooking device, making it easier for users to store their cooking utensils.

[0008] In addition, the cleaning device according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0009] In the above technical solution, the top of the inner cavity is provided with a first opening, and when the frame is located in the washing chamber, the feed port is connected to the first opening; the bottom of the inner cavity is provided with a second opening, and when the frame is located in the unloading chamber, the unloading port is connected to the second opening.

[0010] In this technical solution, a first opening is provided at the top of the inner cavity, and a second opening is provided at the bottom of the inner cavity, making the inner cavity a through-hole. When the frame is located in the washing chamber, the food to be washed and water enter the inner cavity sequentially through the inlet and the first opening, allowing the food to be washed within the inner cavity. After washing, the frame moves, pushing the food along. As the frame enters the discharge chamber, the second opening on the frame gradually aligns with the discharge port, and the washed food inside the frame is discharged sequentially through the second opening and the discharge port, ultimately discharged under gravity. By providing a second opening at the bottom of the frame, no auxiliary components are needed to push the food out of the inner cavity during the discharge process, further simplifying the product structure.

[0011] In one possible technical solution, the cleaning device further includes: a scraper located inside the inner cavity, the scraper being disposed on a drive assembly, the drive assembly being used to drive the scraper to rotate.

[0012] In this technical solution, the drive component can drive the scraper to rotate. During the cleaning process, the scraper rotates in the inner cavity, and the rotating scraper can agitate the food in the inner cavity, so that the food and water in the inner cavity can come into full contact, and the food can be thoroughly rinsed, which is beneficial to improving the cleaning effect of the food.

[0013] The drive assembly can drive the frame to move and the scraper to rotate. It achieves the drive of two working parts through a single drive component, reducing the number of drive components and further simplifying the product structure. The internal structure of the cleaning device is more compact, thereby reducing the size of the cleaning device.

[0014] In one possible technical solution, the scraper contacts or is spaced less than 2 mm from the cavity wall.

[0015] In this technical solution, the scraper contacts the inner cavity wall during rotation, allowing it to not only agitate the food but also scrape away any food adhering to the cavity wall. This prevents unwashed food from entering the cavity and improves the cleaning effectiveness of the washing device. During the feeding process, the scraper also rotates within the cavity, scraping away any food adhering to the cavity wall. This ensures all food in the cavity is discharged through the discharge port, preventing food waste and improving the smoothness of the feeding process. Users are no longer required to manually clean the food from the cavity, simplifying the operation.

[0016] The distance between the scraper and the inner cavity wall can also be set to less than 2mm. The scraper is set close to the inner cavity wall, which can also scrape off the food on the cavity wall and reduce the wear between the scraper and the inner cavity.

[0017] In one possible technical solution, the drive assembly includes: a drive member disposed on the main body; a transmission wheel assembly drivenly connected to the drive member; a transmission shaft assembly drivenly connected to the transmission shaft assembly, with the frame and scraper disposed on the transmission shaft assembly.

[0018] In this technical solution, the driving component can drive the transmission wheel assembly to rotate, the transmission wheel assembly can drive the transmission shaft assembly to rotate, and the rotating shaft assembly can both drive the frame to move and drive the scraper to rotate. By driving the frame and scraper to rotate through a transmission shaft assembly, two sets of structures can be set on the transmission shaft assembly. One set of structures is used to drive the frame to move, and the other set of structures drives the scraper to rotate, which helps to simplify the structure of the product.

[0019] In one possible technical solution, the drive shaft assembly includes: a screw, disposed on the frame, with a mounting hole along the axial direction; a nut, disposed on the main body, with meshing teeth on the outer periphery of the nut, and the screw moving along the axial direction of the nut; a rotating shaft, passing through the mounting hole, with a scraper disposed on the rotating shaft along the axial direction of the screw, the screw and the rotating shaft moving synchronously, and the rotating shaft capable of rotating within the mounting hole; and a drive gear, sleeved on the rotating shaft, wherein when one of the meshing teeth and the drive gear is drivenly connected to the drive wheel assembly, the other is separated from the drive wheel assembly.

[0020] In this technical solution, a nut is installed on the main body, and a screw drives the nut, meaning the screw and nut are assembled and the screw enables the nut to move. Engaging teeth are machined on the outer periphery of the nut, and these teeth can drive a transmission wheel assembly, allowing the nut to rotate on the main body. During use, the drive component drives the transmission wheel assembly to rotate. When the transmission wheel assembly engages with the engaging teeth, it drives the teeth to rotate, causing the nut to rotate on the main body. The frame needs to move relative to the main body. To ensure that the first opening on the frame faces the feed inlet and the second opening faces the discharge outlet, the frame's rotation relative to the main body needs to be restricted. Therefore, the screw is axially movable, driving the frame to translate. When the nut rotates, to restrict the screw's rotation, a limiting structure can be installed on the frame or the main body. This limiting structure restricts the frame's rotation, thus restricting the screw's rotation. Therefore, when the nut rotates, the screw can only translate along the nut's axial direction. The rotating shaft passes through the mounting hole of the screw, and the axial direction of the rotating shaft is the same as that of the screw. Since the scraper is mounted on the rotating shaft, the frame and the scraper can move together, so the screw needs to be configured to drive the rotating shaft. A transmission gear is mounted on the rotating shaft and is fixed to the rotating shaft, so the transmission gear and the rotating shaft can rotate synchronously. The transmission wheel assembly can be driven by the transmission gear. When the scraper needs to be rotated, the transmission wheel assembly drives the transmission gear to rotate, the transmission gear drives the rotating shaft to rotate, and the rotating shaft drives the scraper to rotate. When the transmission wheel assembly drives the meshing gear to rotate, the transmission wheel assembly disengages from the transmission gear. Similarly, when the transmission wheel assembly meshes with the transmission gear, the transmission wheel assembly disengages from the meshing gear. In practical applications, the frame does not need to move when the scraper is scraping material, and the scraper does not need to rotate when the frame is moving. Therefore, the transmission wheel assembly can only engage with one of the meshing gear and the transmission gear at a time to avoid interference between the movement of the frame and the rotation of the scraper, thus improving the stability of the cleaning device during operation.

[0021] In one possible technical solution, the transmission wheel assembly includes: a first drive wheel for meshing with meshing teeth; and a second drive wheel for meshing with transmission wheel teeth. When the first drive wheel meshes with the meshing teeth, the second drive wheel disengages from the transmission gear. When the second drive wheel disengages from the meshing teeth, the second drive wheel disengages from the transmission gear.

[0022] In this technical solution, the driving component can simultaneously drive the first, second, and third driving wheels to rotate. When the frame needs to be moved, the rotating first driving wheel drives the meshing gear to rotate, causing the rotating nut to drive the screw to translate, and the screw to move the frame. When the scraper needs to be rotated, the rotating second driving wheel drives the transmission gear to rotate, which in turn drives the shaft to rotate, causing the shaft to rotate the scraper. When the first driving wheel and the meshing gear are engaged, the frame moves; at this time, the scraper does not need to rotate, and the second driving wheel is disengaged from the transmission gear. When the second driving wheel and the transmission gear are engaged, the scraper rotates; at this time, the frame does not need to move, and the first driving wheel is disengaged from the meshing gear, which helps improve the stability of the cleaning device during operation.

[0023] In one possible technical solution, the first drive wheel includes: a first gear for meshing with a meshing tooth; the second drive wheel includes: a second gear for meshing with a transmission gear when the frame is located in the washing chamber; and a third gear for meshing with a transmission gear when the frame is located in the unloading chamber.

[0024] In this technical solution, the first drive wheel is a first gear, which can mesh with a meshing gear, enabling the first gear to drive the nut to rotate. The second drive wheel includes two gears, a second gear and a third gear, which can mesh with a transmission gear respectively. When the frame is in the washing chamber, the scraper needs to agitate the food; when the frame is in the discharging chamber, the scraper needs to scrape the food in the inner chamber. Therefore, the scraper needs to rotate in both the washing and discharging chambers. The second and third gears are spaced apart along the axial direction of the rotating shaft. When the frame is in the washing chamber, the second gear can mesh with the transmission gear, which can then drive the rotating shaft to rotate. At this time, the scraper rotates in the washing position. After the screw drives the rotating shaft to move, the transmission gear moves a certain distance along the axial direction of the rotating shaft, moving to the vicinity of the third gear. The third gear can then drive the transmission gear to rotate, at which point the scraper rotates in the discharging position. By setting a second and a third gear, the driving function of the transmission gear at different positions is realized. There is no need to set a gear with a long axial length, which helps to simplify the structure of the second drive wheel and reduce the processing difficulty and cost of the product.

[0025] In one possible technical solution, the transmission wheel assembly further includes: a connecting shaft, wherein the first gear, the second gear, and the third gear are spaced apart along the axial direction of the connecting shaft.

[0026] In this technical solution, the first gear, the second gear, and the third gear are mounted on the connecting shaft, making the transmission wheel assembly a single unit, reducing the number of parts in the product, and thus effectively reducing the installation difficulty of the transmission wheel assembly.

[0027] In one possible technical solution, the second and third gears are offset from the first gear along the circumferential direction of the connecting shaft.

[0028] In this technical solution, to ensure that the first gear separates from the meshing teeth when the second and third gears mesh with the transmission gear, the first, second, and third gears are not complete gears. The first gear has teeth on a portion of the connecting shaft in the circumferential direction, while the second and third gears similarly have teeth only on a portion of the connecting shaft in the axial direction. Furthermore, the second gear is offset from the first gear circumferentially along the connecting shaft, and the third gear is also offset from the first gear. For example, when the frame needs to move from the washing chamber to the lower material chamber, the first gear meshes with the meshing teeth. At this time, the second gear is offset from the transmission gear. Even if the first gear rotates, the second gear cannot drive the transmission gear. Similarly, when the second or third gear meshes with the transmission gear, the first gear is offset from the meshing teeth, effectively preventing interference between the movement of the frame and the rotation of the scraper. Furthermore, the second and third gears are spaced apart, so that when the transmission gear moves with the shaft, the transmission gear is located between the second and third gears, thus preventing the rotating second and third gears from contacting the transmission gear and causing tooth knocking. In other words, it avoids interference between the rotating second gear and the transmission gear, as well as interference between the rotating third gear and the transmission gear.

[0029] In one possible technical solution, the screw includes: a first rod body, wherein when the second gear meshes with the transmission gear, the transmission gear is sleeved on the first rod body; a second rod body, wherein a first end is located on the first rod body, and the second rod body has a threaded portion that engages with a nut, wherein when the first gear meshes with the meshing portion, the second gear and the third gear are separated from the transmission gear; and a third rod body, wherein a second end of the second rod body is located on the third rod body, wherein when the third gear meshes with the transmission gear, the transmission gear is sleeved on the third rod body.

[0030] In this technical solution, the screw consists of three parts: a first rod, a second rod, and a third rod, all extending in the same direction. The second rod is located between the first and third rods and has a threaded portion, while the first and third rods do not. Therefore, the nut can only mate with the second rod. For example, when the first gear rotates clockwise, causing the nut to rotate, the second rod engages with the nut, allowing the screw to move axially. When the nut is at the end of the second rod, it is fitted onto the first rod. Since the first rod does not have a threaded structure, the nut cannot move it even if it continues to rotate. At this time, the frame is located inside the washing chamber, and the transmission wheel assembly rotates continuously. The second gear drives the scraper to rotate. While the transmission wheel assembly rotates continuously, the second gear intermittently drives the scraper to rotate. Although the first gear can drive the nut to rotate, the nut cannot move the screw. This achieves the purpose of continuous intermittent rotation of the scraper, which is beneficial for improving the cleaning effect on food. After the ingredients are cleaned, the drive unit rotates the first gear counterclockwise. At this time, the nut engages with the threaded part on the second rod, allowing the nut to move the screw and thus drive the frame into the feeding chamber. Similarly, when the other end of the second rod contacts the nut, the nut cannot move the screw, and the nut is then fitted onto the third rod. The third gear can then intermittently drive the scraper to rotate, improving the scraping effect on the ingredients in the inner cavity.

[0031] In one possible technical solution, the drive assembly further includes: a first elastic element sleeved on the screw, and a second elastic element sleeved on the shaft. When the nut is sleeved on the first rod, the first elastic element is in an elastic deformation state, and the second elastic element is in its original state. When the nut is sleeved on the second rod, the first elastic element is in its original state, and the second elastic element is in an elastic deformation state.

[0032] In this technical solution, when the nut is fitted onto the first rod, the first elastic element is in an elastic deformation state. At this time, the first elastic element tends to push the screw, allowing the nut to stably contact the threaded portion on the first end of the second rod. When the first gear rotates counterclockwise, the nut can stably engage with the second rod to drive its movement. Similarly, when the nut is fitted onto the third rod, the second elastic element is in an elastic deformation state. At this time, the second elastic element tends to push the screw, allowing the screw to stably contact the threaded portion on the second end of the second rod. By incorporating both the first and second elastic elements, the stability of the engagement between the nut and the second rod can be improved.

[0033] In one possible technical solution, the frame is also provided with a seal, which is located at the top and bottom of the frame and is in contact with the main body.

[0034] In this technical solution, the frame can move relative to the main body. To avoid interference between the main body and the frame, a gap needs to be set between the main body and the frame. During the food washing process, to prevent water and food from overflowing through the gap between the main body and the frame, seals are installed at the top and bottom of the frame. The seals seal the gap between the main body and the frame, preventing food and water from overflowing. This not only prevents sewage from overflowing and causing the washing device to become dirty, but also prevents food from overflowing and getting stuck between the frame and the main body, which helps to improve the smoothness of the washing process.

[0035] The seals are made of a relatively soft material, making them less prone to damage when the frame moves, thus improving the structural stability of the cleaning device.

[0036] A second aspect of the present invention provides a cooking appliance, comprising: a body; a pot assembly detachably disposed on the body; and a cleaning device as described in any possible technical solution of the first aspect, wherein the cleaning device is disposed on the body, the pot assembly is provided with a rice inlet, and the rice inlet is connected to the feeding port in the cleaning device.

[0037] The pot body assembly can be placed on or separated from the main body. That is, the pot body assembly and the main body are detachable. When it is necessary to add or store food, or to clean the pot body assembly, it can be separated from the main body, allowing the user to use the pot body assembly independently. Furthermore, because the pot body assembly and the main body are detachable, heating components can be located on the main body, meaning there is no need for electrical components on the pot body assembly. This reduces the risk of water damage to the electrical components during cleaning, improving the stability and safety of the cooking appliance. The pot body assembly has a rice inlet. When cooking is required, rice from the cleaning device is discharged through the discharge port, which is connected to the rice inlet, thus achieving an automatic rice feeding function.

[0038] For example, the pot assembly includes a lid and a pot body. The lid covers the opening of the pot body. A pushable valve can be provided on the lid to close the rice inlet. A pushing component can be provided on the pot body. When rice needs to be added, the pushing component pushes the valve on the lid to open the rice inlet, allowing rice from the feed chute to fall directly into the rice inlet. By setting the valve to close the rice inlet, rapid heat loss from the pot body during cooking is prevented.

[0039] In one possible technical solution, the main body is provided with a receiving part, and the pot assembly is located inside the receiving part.

[0040] In this technical solution, when the pot assembly is placed within the receiving section of the main body, the main body can heat the pot assembly to achieve the cooking function. For example, a heating element can be installed on the main body, located at the bottom of the pot assembly, which can heat the pot assembly. The receiving section houses the pot assembly, preventing it from coming into contact with external parts during cooking, thus avoiding burns to the user. Furthermore, the reduced contact with other parts during cooking improves stability. By providing a receiving section on the main body, the pot assembly does not need to be placed on the outer surface of the main body, reducing the space occupied by the cooking appliance and making it easier for the user to store it. When the user needs to use the pot assembly separately, it can be removed from the receiving section.

Detailed Implementation

[0053] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 8 The present invention describes a cleaning apparatus and a cooking appliance provided according to some embodiments thereof.

[0056] Combination Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments of this application, a cleaning device is proposed, comprising: a main body 100, on which an inlet 110 and a washing chamber 120 are provided, the inlet 110 being connected to the washing chamber 120, and a discharge chamber 130 and a discharge port 140 being connected; a frame 200, having an inner cavity 210 and a drain outlet, the drain outlet being connected to the inner cavity 210, wherein when the current position of the frame 200 is within the washing chamber 120, the inlet 110 and the inner cavity 210 are connected, and when the current position of the frame 200 is within the discharge chamber 130, the discharge port 140 and the inner cavity 210 are connected; and a driving assembly 300, disposed on the main body 100, for driving the frame 200 to move between the washing chamber 120 and the discharge chamber 130.

[0057] The cleaning device provided in this embodiment has a frame 200 that can move relative to the main body 100. When cleaning is required, the frame 200 is located in the washing chamber 120, and the food and water to be cleaned enter the chamber. After cleaning, the frame 200 is located in the discharge chamber 130, and the cleaned food is discharged from the chamber. Specifically, the food and water to be cleaned enter the inner cavity 210 of the frame 200 through the inlet 110. The food is cleaned in the inner cavity 210. There are various cleaning methods, such as setting an agitator to agitate the inner cavity 210, or driving the frame 200 to vibrate through a vibrating element. After the ingredients are washed, the wastewater in the washing chamber 120 is discharged through the drain outlet, leaving the washed ingredients in the inner chamber 210. The drive component 300 can drive the frame 200 to move, allowing the frame 200 to move into the dispensing chamber 130. During the movement of the frame 200, the frame 200 can move the ingredients in the inner chamber 210 together, so that the frame 200 and the ingredients move together into the dispensing chamber 130. The inner chamber 210 is connected to the dispensing port 140, and the ingredients in the inner chamber 210 are discharged through the dispensing port 140. The washed ingredients can then enter the container of the cooking utensil, thus completing the dispensing function. When the frame 200 is located in the washing chamber 120, the bottom of the frame 200 is in contact with the bottom wall of the washing chamber 120, making it difficult for the ingredients and water in the inner chamber 210 to flow out of the inner chamber 210. When the frame 200 moves, the side wall of the frame 200 pushes the ingredients, causing them to be pushed into the dispensing chamber 130. By setting up a movable frame 200, the frame 200 can realize the functions of cleaning ingredients and dispensing ingredients when it is located in different cavities. It eliminates the need to complete the cleaning process of ingredients inside the container, simplifies the structure of the container, reduces the processing difficulty of the container, and separates the cleaning device from the container. When the container is heated, the cleaning device is not easily damaged by high temperature, which helps to improve the functional stability of the cooking appliance equipped with the cleaning device.

[0058] By setting a washing chamber 120 and a discharging chamber 130 on the main body 100, the cleaning device can complete the functions of washing and discharging at the same time. It does not require two separate components, which simplifies the structure of the product and reduces the volume occupied by the cleaning device. This reduces the space occupied by the cooking device, making it easier for users to store cooking utensils.

[0059] Combination Figure 1 and Figure 2 As shown, in one possible embodiment, the top of the inner cavity 210 is formed with a first opening 220, and when the current position of the frame 200 is in the washing chamber 120, the feed port 110 and the first opening 220 are connected; the bottom of the inner cavity 210 is formed with a second opening 230, and when the current position of the frame 200 is in the unloading chamber 130, the unloading port 140 and the second opening 230 are connected.

[0060] In this embodiment, a first opening 220 is provided at the top of the inner cavity 210, and a second opening 230 is provided at the bottom of the inner cavity 210. Therefore, the inner cavity 210 is a vertically continuous cavity. When the frame 200 is located in the washing chamber 120, the food to be washed and water enter the inner cavity 210 sequentially through the inlet 110 and the first opening 220, allowing the food to be washed in the inner cavity 210. After the food is washed, the frame 200 moves to push the food. As the frame 200 enters the discharge chamber 130, the second opening 230 on the frame 200 gradually aligns with the discharge port 140. The washed food in the frame 200 is discharged sequentially through the second opening 230 and the discharge port 140, and the food to be washed is discharged under gravity. By providing a second opening 230 at the bottom of the frame 200, during the discharge process, there is no need for auxiliary components to push the food out of the inner cavity 210, which further simplifies the product structure.

[0061] Combination Figure 1 , Figure 2 and Figure 4 As shown, in one possible embodiment, the cleaning device further includes a scraper 400 located inside the inner cavity 210, the scraper 400 being mounted on a drive assembly 300, and the drive assembly 300 being capable of driving the scraper 400 to rotate.

[0062] In this embodiment, the drive component 300 can drive the scraper 400 to rotate. During the cleaning process of the food, the scraper 400 rotates in the inner cavity 210. The rotating scraper 400 can agitate the food in the inner cavity 210, so that the food and water in the inner cavity 210 can come into full contact, and the food can be thoroughly rinsed, which is beneficial to improving the cleaning effect of the food.

[0063] The drive assembly 300 can drive the frame 200 to move and drive the scraper 400 to rotate. By using one drive component to drive two working components, the number of drive components is reduced, further simplifying the product structure. The internal structure of the cleaning device is more compact, thereby reducing the volume of the cleaning device.

[0064] In one possible embodiment, the cavity wall of the inner cavity 210 is in contact with or less than 2 mm away from the scraper 400.

[0065] In this embodiment, the scraper 400 contacts the cavity wall of the inner cavity 210 during rotation, allowing it to not only agitate the food but also scrape away any food adhering to the cavity wall, preventing unwashed food from entering and improving the cleaning effectiveness of the washing device. During the feeding process, the scraper 400 also rotates within the inner cavity 210, scraping away any food adhering to the cavity wall, ensuring all food in the inner cavity 210 is discharged through the discharge port 140, preventing food waste, improving the smoothness of the feeding process, and simplifying user operation by eliminating the need for manual cleaning of the food in the inner cavity 210.

[0066] The distance between the scraper 400 and the cavity wall of the inner cavity 210 can also be set to less than 2mm. The scraper 400 and the cavity wall of the inner cavity 210 are set close together, which can also scrape off the food on the cavity wall and reduce the wear of the scraper 400 and the inner cavity 210.

[0067] Combination Figure 1 , Figure 2 and Figure 3 As shown, in one possible embodiment, the drive assembly 300 includes: a drive member 310, a transmission wheel assembly 320, and a transmission shaft assembly 330. The drive member 310 is mounted on the main body 100; the transmission wheel assembly 320 and the drive member 310 are drivenly connected; the transmission shaft assembly 330 and the transmission shaft assembly 330 are drivenly connected, and the scraper 400 and the frame 200 are both disposed on the transmission shaft assembly 330.

[0068] In this embodiment, the drive component 310 can drive the transmission wheel assembly 320 to rotate, and the transmission wheel assembly 320 can drive the transmission shaft assembly 330 to rotate. The rotating shaft assembly can both drive the frame 200 to move and drive the scraper 400 to rotate. By using one transmission shaft assembly 330 to drive the frame 200 and the scraper 400 to rotate, two sets of structures can be set on the transmission shaft assembly 330. One set of structures is used to drive the frame 200 to move, and the other set of structures drives the scraper 400 to rotate, which helps to simplify the structure of the product.

[0069] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in one possible embodiment, the drive shaft assembly 330 includes: a screw 331 disposed on the frame 200, the screw 331 having an axial mounting hole; a nut 332 disposed on the main body 100, the outer periphery of the nut 332 being machined with meshing teeth, the screw 331 being able to move along the axial direction of the nut 332; a rotating shaft 333 passing through the mounting hole, the scraper 400 being mounted on the rotating shaft 333, the screw 331 and the rotating shaft 333 being able to move synchronously along the axial direction of the screw 331, the rotating shaft 333 being able to rotate within the mounting hole; and a drive gear 334 sleeved on the rotating shaft 333, one of the meshing teeth and the drive gear 334 being driven connected to the drive wheel assembly 320, the other being separated from the drive wheel assembly 320.

[0070] In this embodiment, a nut 332 is installed on the main body 100, and a screw 331 can assemble the nut 332, that is, the screw 331 can move the nut 332. The screw 331 can move the nut 332. Engaging teeth are machined on the outer periphery of the nut 332. The engaging teeth can be driven to connect with the transmission wheel assembly 320. The nut 332 can rotate on the main body 100. In use, the driving member 310 drives the transmission wheel assembly 320 to rotate. When the transmission wheel assembly 320 cooperates with the engaging teeth, the transmission wheel assembly 320 can drive the engaging teeth to rotate, so that the nut 332 rotates on the main body 100. The frame 200 needs to move relative to the main body 100. In order for the first opening 220 on the frame 200 to be directly opposite the feed inlet 110 and the second opening 230 to be directly opposite the discharge outlet 140, it is necessary to restrict the rotation of the frame 200 relative to the main body 100. Therefore, the screw 331 is set to move axially, so that the screw 331 drives the frame 200 to translate. When the nut 332 rotates, in order to restrict the rotation of the screw 331, a limiting structure can be set on the frame 200 or the main body 100. The limiting structure restricts the rotation of the frame 200, thereby restricting the rotation of the screw 331. Therefore, when the nut 332 rotates, the screw 331 can only translate along the axial direction of the nut 332. The rotating shaft 333 passes through the mounting hole of the screw 331. The axial direction of the rotating shaft 333 is the same as that of the screw 331. Since the scraper 400 is mounted on the rotating shaft 333, the frame 200 and the scraper 400 can move together. Therefore, the screw 331 needs to be able to drive the rotating shaft 333 to move. A transmission gear 334 is mounted on the rotating shaft 333 and is fixed to the rotating shaft 333, so the transmission gear 334 and the rotating shaft 333 can rotate synchronously. The transmission wheel assembly 320 can be driven to connect with the transmission gear 334. When it is necessary to control the rotation of the scraper 400, the transmission wheel assembly 320 drives the transmission gear 334 to rotate, the transmission gear 334 drives the rotating shaft 333 to rotate, and the rotating shaft 333 drives the scraper 400 to rotate. When the transmission wheel assembly 320 drives the meshing teeth to rotate, the transmission wheel assembly 320 separates from the transmission gear 334. Similarly, when the transmission wheel assembly 320 meshes with the transmission gear 334, the transmission wheel assembly 320 separates from the meshing teeth. In practical applications, the scraper 400 does not need to move the frame 200 when scraping material, and the scraper 400 does not need to rotate when the frame 200 moves. Therefore, the transmission wheel assembly 320 is designed to engage with only one of the meshing teeth and the transmission gear 334 at the same time to avoid interference between the movement of the frame 200 and the rotation of the scraper 400, thereby improving the stability of the cleaning device during operation.

[0071] like Figure 1As shown, in one possible application, a limiting rod 240 is provided on one side of the frame 200, and a guide hole is provided on the main body 100. The limiting rod 240 is inserted into the guide hole and can slide within the guide hole. The guide hole limits the limiting rod 240, thereby restricting the frame 200 from rotating. The limiting rod 240 also guides the frame 200, allowing it to move stably between the washing chamber 120 and the unloading chamber 130. To ensure that the limiting rod 240 can stably achieve the above functions, at least two limiting rods 240 are provided.

[0072] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one possible embodiment, the transmission wheel assembly 320 includes: a first drive wheel 321 and a second drive wheel 322, wherein the first drive wheel 321 is capable of meshing with meshing teeth; the second drive wheel 322 is capable of meshing with transmission wheel teeth. When the first drive wheel 321 is meshed with the meshing teeth, the second drive wheel 322 and the transmission gear 334 are in a disengaged state. When the second drive wheel 322 and the meshing teeth are meshed, the second drive wheel 322 is disengaged from the transmission gear 334.

[0073] In this embodiment, the driving component 310 can simultaneously drive the first driving wheel 321, the second driving wheel 322, and the third driving wheel to rotate. When the frame 200 needs to be moved, the rotating first driving wheel 321 drives the meshing gear to rotate, causing the rotating nut 332 to drive the screw 331 to translate, and the screw 331 drives the frame 200 to move. When the scraper 400 needs to be rotated, the rotating second driving wheel 322 drives the transmission gear 334 to rotate, and the transmission gear 334 drives the rotating shaft 333 to rotate, causing the rotating shaft 333 to drive the scraper 400 to rotate. When the first driving wheel 321 and the meshing gear are engaged, the function of moving the frame 200 is achieved. At this time, the scraper 400 does not need to rotate, and the second driving wheel 322 and the transmission gear 334 are disengaged. When the second drive wheel 322 and the transmission gear 334 mesh, the scraper 400 rotates. At this time, the frame 200 does not need to move. Separating the first drive wheel 321 from the meshing gear helps to improve the stability of the cleaning device during operation.

[0074] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in one possible embodiment, the first drive wheel 321 includes a first gear for meshing with a meshing tooth; the second drive wheel 322 includes a second gear 3321 and a third gear 3322. When the frame 200 is located in the washing chamber 120, the second gear 3321 can mesh with the transmission gear 334; when the current position of the frame 200 is located in the unloading chamber 130, the third gear 3322 can mesh with the transmission gear 334.

[0075] In this embodiment, the first drive wheel 321 is a first gear, which can mesh with meshing teeth, enabling the first gear to drive the nut 332 to rotate. The second drive wheel 322 includes two gears, namely the second gear 3321 and the third gear 3322, which can mesh with the transmission gear 334 respectively. When the frame 200 is located in the washing chamber 120, the scraper 400 needs to agitate the food. When the frame 200 is located in the discharging chamber 130, the scraper 400 needs to scrape the food in the inner cavity 210. Therefore, the scraper 400 needs to rotate in both the washing chamber 120 and the discharging chamber 130, meaning that the scraper 400 needs to perform the function of rotation in both positions. The second gear 3321 and the third gear 3322 are spaced apart along the axial direction of the rotating shaft 333. When the frame 200 is located inside the washing chamber 120, the second gear 3321 can mesh with the transmission gear 334. At this time, the second gear 3321 can drive the rotating shaft 333 to rotate through the transmission gear 334. The scraper 400 rotates at the washing position. After the screw 331 drives the rotating shaft 333 to move, the transmission gear 334 moves a certain distance along the axial direction of the rotating shaft 333. At this time, the transmission gear 334 moves to the vicinity of the third gear 3322, and the third gear 3322 can drive the transmission gear 334 to rotate. At this time, the scraper 400 rotates at the unloading position. By setting the second gear 3321 and the third gear 3322, the driving function of the transmission gear 334 at different positions is realized. It is not necessary to set a gear with a long axial length, which helps to simplify the structure of the second drive wheel 322 and reduce the processing difficulty and processing cost of the product.

[0076] Combination Figure 5 and Figure 6 As shown, in one possible embodiment, the transmission wheel assembly 320 further includes a connecting shaft 323, and a first gear, a second gear 3321 and a third gear 3322 are spaced apart on the connecting shaft 323 along the axial direction of the connecting shaft 323.

[0077] In this embodiment, the first gear, the second gear 3321, and the third gear 3322 are mounted on the connecting shaft 323, making the transmission wheel assembly 320 a single integral component, reducing the number of parts in the product, and thus effectively reducing the installation difficulty of the transmission wheel assembly 320.

[0078] Combination Figure 5 and Figure 6 As shown, in one possible embodiment, along the circumference of the connecting shaft 323, the second gear 3321 and the third gear 3322 are offset from the first gear.

[0079] In this embodiment, in order to satisfy the function of separating the first gear from the meshing teeth when the second gear 3321 and the third gear 3322 mesh with the transmission gear 334, the first gear, the second gear 3321 and the third gear 3322 are not complete gears. The first gear has a tooth structure in the circumferential direction of a portion of the connecting shaft 323. Similarly, the second gear 3321 and the third gear 3322 only have tooth structures in the axial direction of a portion of the connecting shaft 323. Moreover, the second gear 3321 is offset from the first gear and the third gear 3322 is offset from the first gear in the circumferential direction of the connecting shaft 323. For example, when the frame 200 needs to move from the washing chamber 120 to the lower material chamber 130, the first gear engages with the meshing teeth. At this time, the second gear 3321 is disengaged from the transmission gear 334. Even if the first gear rotates, the second gear 3321 cannot drive the transmission gear 334. Similarly, when the second gear 3321 or the third gear 3322 engages with the transmission gear 334, the first gear is disengaged from the meshing teeth, effectively avoiding interference between the movement of the frame 200 and the rotation of the scraper 400. Furthermore, the second gear 3321 and the third gear 3322 are spaced apart. When the transmission gear 334 moves with the rotating shaft 333, the transmission gear 334 is located between the second gear 3321 and the third gear 3322, which avoids the rotating second gear 3321 and the third gear 3322 from contacting the transmission gear 334 and thus preventing tooth knocking. In other words, it avoids interference between the rotating second gear 3321 and the transmission gear 334, as well as interference between the rotating third gear 3322 and the transmission gear 334.

[0080] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in one possible embodiment, the screw 331 includes: a first rod body 3311, a second rod body 3312, and a third rod body 3313. When the second gear 3321 meshes with the transmission gear 334, the transmission gear 334 is sleeved on the first rod body 3311. The first end is located on the first rod body 3311. The second rod body 3312 is provided with a threaded portion, which cooperates with the nut 332. When the first gear meshes with the meshing portion, the second gear 3321 and the third gear 3322 are separated from the transmission gear 334. The third rod body 3313 is located at the second end of the second rod body 3312. When the third gear 3322 meshes with the transmission gear 334, the transmission gear 334 is sleeved on the third rod body 3313.

[0081] In this embodiment, the screw 331 consists of three parts: a first rod 3311, a second rod 3312, and a third rod 3313 extending in the same direction. The second rod 3312 is located between the first rod 3311 and the third rod 3313. The second rod 3312 is provided with a threaded portion, while the first rod 3311 and the third rod 3313 are not provided with threaded portions. Therefore, the nut 332 can only be mated with the second rod 3312. For example, when the first gear rotates clockwise and drives the nut 332 to rotate, the second rod 3312 engages with the nut 332. At this time, the screw 331 can move axially. When the nut 332 is at the end of the second rod 3312, the nut 332 is sleeved on the first rod 3311. Since the first rod 3311 does not have a threaded structure, the nut 332 cannot drive the first rod 3311 to move even if it continues to rotate. At this time, the frame 200 is located in the washing chamber 120, the transmission wheel assembly 320 rotates continuously, and the second gear 3321 can drive the scraper 400 to rotate. When the transmission wheel assembly 320 rotates continuously, the second gear 3321 intermittently drives the scraper 400 to rotate. At this time, although the first gear can drive the nut 332 to rotate, the nut 332 cannot drive the screw 331 to move. This achieves the purpose of continuous intermittent rotation of the scraper 400, which is beneficial to improving the cleaning effect on the food. After the ingredients are cleaned, the drive unit 310 drives the first gear to rotate counterclockwise. At this time, the nut 332 can engage with the threaded part on the second rod 3312, allowing the nut 332 to drive the screw 331 to move, thereby driving the frame 200 into the feeding chamber 130. Similarly, when the other end of the second rod 3312 contacts the nut 332, the nut 332 cannot drive the screw 331 to move. At this time, the nut 332 is fitted onto the third rod 3313. At this time, the third gear 3322 can intermittently drive the scraper 400 to rotate, improving the scraping effect of the scraper 400 on the ingredients in the inner cavity 210.

[0082] Combination Figure 1 and Figure 2 As shown, in one possible embodiment, the drive assembly 300 further includes: a first elastic element 500 sleeved on the screw 331, and a second elastic element 600 sleeved on the rotating shaft 333. When the nut 332 is sleeved on the first rod 3311, the first elastic element 500 is in an elastic deformation state, while the second elastic element 600 is in the original state. When the nut 332 is sleeved on the second rod 3312, the first elastic element 500 is in the original state, while the second elastic element 600 is in an elastic deformation state.

[0083] In this embodiment, when the nut 332 is fitted onto the first rod 3311, the first elastic element 500 is in an elastic deformation state. At this time, the first elastic element 500 tends to push the screw 331, allowing the nut 332 to stably contact the threaded portion on the first end of the second rod 3312. When the first gear rotates counterclockwise, the nut 332 can stably engage with the second rod 3312, thereby driving the second rod 3312 to move. Similarly, when the nut 332 is fitted onto the third rod 3313, the second elastic element 600 is in an elastic deformation state. At this time, the second elastic element 600 tends to push the screw 331, allowing the screw 331 to stably contact the threaded portion on the second end of the second rod 3312. By providing the first elastic element 500 and the second elastic element 600, the engagement stability of the nut 332 and the second rod 3312 can be improved.

[0084] like Figure 1 As shown, in one possible embodiment, a seal 700 is installed on the frame 200, specifically, the top and bottom of the frame 200 are provided with seals 700, and the main body 100 is in contact with the seal 700.

[0085] In this embodiment, the frame 200 is movable relative to the main body 100. To avoid interference between the main body 100 and the frame 200, a gap needs to be provided between the main body 100 and the frame 200. During the food washing process, to prevent water and food from overflowing through the gap between the main body 100 and the frame 200, a sealing element 700 is provided at both the top and bottom of the frame 200. The sealing element 700 seals the gap between the main body 100 and the frame 200, preventing food and water from overflowing. This not only prevents sewage from overflowing and causing the washing device to become dirty, but also prevents food from overflowing and getting stuck between the frame 200 and the main body 100, which helps to improve the smoothness of the washing process.

[0086] The seal 700 is made of a relatively soft material, so it is not easily damaged when the frame 200 moves, thus improving the structural stability of the cleaning device.

[0087] Combination Figure 1 and Figure 8 As shown, in some embodiments of this application, a cooking appliance is proposed, including: a body 800; a pot assembly 900, the pot assembly 900 being detachably disposed on the body 800; and a cleaning device as in any of the above possible embodiments, the cleaning device being installed on the body 800, the pot assembly 900 being provided with a rice inlet, and the discharge port 140 in the cleaning device being connected to the rice inlet.

[0088] The pot assembly 900 can be placed on or separated from the main body 800. That is, the pot assembly 900 and the main body 800 are detachable. When it is necessary to add or store food, or to clean the pot assembly 900, it can be separated from the main body 800 for convenient use by the user. Furthermore, because the pot assembly 900 and the main body 800 are detachable, heating components can be located on the main body 800. This eliminates the need for electrical components on the pot assembly 900, reducing the risk of damage to the pot assembly 900 due to water ingress during cleaning, thus improving the stability and safety of the cooking appliance. The pot assembly 900 is equipped with a rice inlet. When cooking is required, rice from the cleaning device is discharged through the discharge port 140, which is connected to the rice inlet, enabling automatic rice feeding.

[0089] For example, the pot assembly 900 includes a lid and a pot body. The lid is positioned over the opening of the pot body. A pushable valve can be provided on the lid to close the rice inlet. A pushing component can be provided on the body 800. When rice is needed, the pushing component pushes the valve on the lid to open the rice inlet, allowing rice from the discharge port 140 to fall directly into the rice inlet. By using a valve to close the rice inlet, rapid heat loss from the pot body during cooking is prevented.

[0090] When the cooking appliance needs to be used, the frame 200 is located in the washing chamber 120. The ingredients to be washed and water enter the chamber. After the ingredients are washed, the frame 200 is located in the discharge chamber 130, and the washed ingredients are discharged from the chamber. Specifically, the ingredients to be washed and water enter the inner cavity 210 of the frame 200 through the inlet 110. The ingredients to be washed are washed in the inner cavity 210. There are various washing methods, such as setting up an agitator to agitate the inner cavity 210, or driving the frame 200 to vibrate through a vibrating component. After the ingredients are washed, the wastewater in the washing chamber 120 is discharged through the drain outlet, leaving the washed ingredients in the inner chamber 210. The drive component 300 can drive the frame 200 to move, allowing the frame 200 to move into the dispensing chamber 130. During the movement of the frame 200, the frame 200 can move the ingredients in the inner chamber 210 together, so that the frame 200 and the ingredients move together into the dispensing chamber 130. The inner chamber 210 is connected to the dispensing port 140, and the ingredients in the inner chamber 210 are discharged through the dispensing port 140. The washed ingredients can then enter the container of the cooking utensil, thus completing the dispensing function. When the frame 200 is located in the washing chamber 120, the bottom of the frame 200 is in contact with the bottom wall of the washing chamber 120, making it difficult for the ingredients and water in the inner chamber 210 to flow out of the inner chamber 210. When the frame 200 moves, the side wall of the frame 200 pushes the ingredients, causing them to be pushed into the dispensing chamber 130. By setting up a movable frame 200, the frame 200 can realize the functions of cleaning ingredients and dispensing ingredients when it is located in different cavities. It eliminates the need to complete the cleaning process of ingredients inside the container, simplifies the structure of the container, reduces the processing difficulty of the container, and separates the cleaning device from the container. When the container is heated, the cleaning device is not easily damaged by high temperature, which helps to improve the functional stability of the cooking appliance equipped with the cleaning device.

[0091] By setting a washing chamber 120 and a discharging chamber 130 on the main body 100, the cleaning device can complete the functions of washing and discharging at the same time. It does not require two separate components, which simplifies the structure of the product and reduces the volume occupied by the cleaning device. This reduces the space occupied by the cooking device, making it easier for users to store cooking utensils.

[0092] The inner cavity 210 has a first opening 220 at the top and a second opening 230 at the bottom, making it a through-cavity. When the frame 200 is located in the washing chamber 120, the food to be washed and water enter the inner cavity 210 sequentially through the inlet 110 and the first opening 220, allowing the food to be washed within the inner cavity 210. After washing, the frame 200 moves, pushing the food along. As the frame 200 enters the discharge chamber 130, the second opening 230 on the frame 200 gradually aligns with the discharge port 140, and the washed food is discharged sequentially through the second opening 230 and the discharge port 140, ultimately discharged under gravity. By providing the second opening 230 at the bottom of the frame 200, no auxiliary components are needed to push the food out of the inner cavity 210 during the discharge process, further simplifying the product structure.

[0093] In this embodiment, the cooking appliance is a rice cooker. In other embodiments, the cooking appliance may also be a coffee machine, a soy milk maker, etc.

[0094] like Figure 8 As shown, in one possible embodiment, the body 800 is provided with a receiving portion 810, and the pot assembly 900 is located within the receiving portion 810.

[0095] In this embodiment, when the pot assembly 900 is placed inside the receiving portion 810 of the main body 800, the main body 800 can heat the pot assembly 900 to achieve the cooking function. For example, a heating element can be provided on the main body 800, located at the bottom of the pot assembly 900, which can heat the pot assembly 900. The receiving portion 810 serves to contain the pot assembly 900, preventing it from coming into contact with external parts during cooking, thus avoiding the problem of scalding the user. Moreover, preventing other parts from cooking the pot assembly 900 also improves the stability during cooking. By providing the receiving portion 810 on the main body 800, it is not necessary to place the pot assembly 900 on the outer surface of the main body 800, which helps to reduce the space occupied by the cooking appliance and makes it easier for the user to store the cooking appliance. When the user needs to use the pot assembly 900 alone, the pot assembly 900 can be removed from the receiving portion 810. The inner cavity 210 is also equipped with a scraper 400 mounted on the drive assembly 300. The scraper 400 rotates in the inner cavity 210. The rotating scraper 400 can agitate the food in the inner cavity 210, so that the food and water in the inner cavity 210 can come into full contact, so that the food can be thoroughly rinsed, which is beneficial to improving the cleaning effect of the food.
