[0059] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] With the continuous advancement of industrial technology and the significant improvement of people's living standards, the variety of electrical appliances has increased, providing people with numerous conveniences. Among them, the dishwasher is a kitchen appliance used to clean tableware, capable of automatically completing a series of operations such as washing, disinfecting, and drying tableware.

[0061] In related technologies, dishwashers typically include a washing chamber, as well as spray arms and a dish rack located within the washing chamber. After the user places the dishes in the dish rack and starts the washing program, the spray arms spray the dishes in the rack to remove stains and complete the cleaning task. However, this cleaning process is prone to ineffective cleaning, and improving the cleaning result often requires more water and time, leading to a poor user experience.

[0062] One of the core concepts of this invention is that the dishwasher is divided into a first cleaning zone, a second cleaning zone, and a drying zone connected sequentially, and multiple movable storage modules are provided to allow the tableware to move between these zones. After being washed uniformly in the first cleaning zone, the tableware is moved in batches to the second cleaning zone for further washing. This batch washing method reduces the density of the tableware, thereby improving the cleaning effect and enhancing the user experience. Furthermore, after washing, all the tableware is moved to the drying zone for drying. Since the drying zone is free of moisture and residue from washing the tableware, the drying environment is drier and cleaner, thus improving drying efficiency and effect, further enhancing the user experience.

[0063] Figure 1This is a schematic diagram of the structure of a dishwasher provided in an embodiment of the present invention.

[0064] like Figure 1 As shown, the dishwasher includes: a first cleaning zone 110, a second cleaning zone 120, and a drying zone 130 connected in sequence;

[0065] It is understood that a dishwasher includes three working chambers connected in sequence, which are divided into a first cleaning zone, a second cleaning zone, and a drying zone according to their working areas.

[0066] Multiple movable storage modules 140 are used to place tableware and move within the first washing area 110, the second washing area 120 and the drying area 130;

[0067] In practical applications, users place the tableware to be cleaned onto the storage module, which then moves the tableware from the first cleaning area to the second cleaning area and the drying area in sequence, completing the cleaning process.

[0068] The control module is used to control the multiple placement modules 140 to remain in the first cleaning area 110 to complete the first cleaning process; after the first cleaning process, the following steps are repeated: control the placement modules in the first cleaning area to move to the second cleaning area in batches to complete the second cleaning process; after the second cleaning process, control the placement modules in the second cleaning area to move to the drying area until all the tableware is moved to the drying area to complete the drying process.

[0069] In practical applications, the control module is typically a control motherboard or similar device, and is usually located inside the dishwasher, far from the working chamber. Therefore, the control module is not... Figure 1 As shown in the image.

[0070] This invention divides the dishwasher into a first cleaning zone, a second cleaning zone, and a drying zone connected sequentially, and incorporates multiple movable storage modules to allow for the movement of tableware across these zones. After being washed uniformly in the first cleaning zone, the tableware is then moved in batches to the second cleaning zone for further washing. This batch washing method reduces the density of the tableware, thereby improving the cleaning effect and enhancing the user experience. Furthermore, after washing, all tableware is moved to the drying zone for drying. Since the drying zone is free of moisture and residue from washing, the drying environment is drier and cleaner, improving drying efficiency and effectiveness, further enhancing the user experience.

[0071] Figure 2 This is a schematic diagram of the structure of a storage module provided in an embodiment of the present invention.

[0072] like Figure 2As shown, in some embodiments, the storage module includes: a moving component 141 and a storage component 142; the storage component 142 is fixed to the top of the moving component 141 and is used to place the tableware; the moving component 141 is used to drive the storage module to move.

[0073] As an example, the storage component can be a shelf, and different sizes of shelves can be determined as storage components according to different types of tableware. For example, some storage modules have taller shelves for placing plates, while others have shorter shelves for placing bowls.

[0074] The structure of this storage module ensures that the tableware can be moved while being fixed in place by the storage component, thus guaranteeing the reliability of the tableware movement operation.

[0075] In some embodiments, the storage module includes a drive device, and the moving part includes a drive wheel. The drive device may be a drive motor, which is connected to the drive wheel. When the control motherboard controls the drive motor to start, it drives the drive wheel to rotate, thereby realizing the movement of the storage module.

[0076] In some embodiments, the dishwasher includes:

[0077] Multiple guide rails, corresponding to the multiple storage modules, are parallel to each other and extend from the first cleaning area to the second cleaning area and the drying area.

[0078] It is understandable that the guide rails are installed on the bottom surface of the first washing zone, the second washing zone, and the drying zone, with a sufficiently large distance between each rail to ensure that adjacent storage modules can move simultaneously without interference. Multiple storage modules are also arranged in parallel, with each module corresponding to one guide rail, ensuring that the modules move along a fixed direction and route along their respective rails between the first washing zone, the second washing zone, and the drying zone. This guide rail arrangement ensures that multiple storage modules do not interfere with each other when moving simultaneously, thus guaranteeing the normal operation of the dishwasher.

[0079] In some embodiments, the bottom of the moving component is provided with an electromagnet assembly, and when the electromagnet assembly is energized, the placement module is attracted to the guide rail.

[0080] It is understandable that a high-pressure water jet is needed to rinse the tableware during the cleaning process. To prevent the storage module from moving due to the impact of water pressure, an electromagnet assembly is considered to be installed at the bottom of the moving parts of the storage module.

[0081] When the dishwasher control system de-energizes the electromagnet assembly, the electromagnet assembly is non-magnetic, allowing the dish rack to move on the guide rail using the rollers of the moving parts. When the dish rack moves to the designated area, the dishwasher control system energizes the electromagnet assembly, causing it to become magnetic and attract the dish rack onto the guide rail. This secures the dish rack and prevents it from moving during rinsing, ensuring effective cleaning.

[0082] Figure 3 This is a schematic diagram of another dishwasher provided in an embodiment of the present invention;

[0083] like Figure 3 As shown, in some embodiments, the first cleaning zone 110 includes: a first cleaning device 111;

[0084] The first cleaning device 111 is disposed on the top of the first cleaning area 110 and is used to perform the first cleaning process on the tableware on the multiple storage modules 140 in the first cleaning area 110.

[0085] In practical applications, the dishwasher's initial working state is that all placement modules are in the first cleaning zone. After the user places the dishes to be cleaned in the placement modules and starts the dishwasher, the control module controls the first cleaning device to perform the first cleaning process on all the dishes to be cleaned in the first cleaning zone.

[0086] As an example, the user opens the cabinet door of the first cleaning zone, places the dishes to be washed on the storage module within the first cleaning zone, closes the cabinet door, and starts the dishwasher. The control module then controls the first cleaning device to generate a high-pressure fan-shaped water curtain, rinsing the dishes in the first cleaning zone. The high-pressure fan-shaped water curtain removes easily detachable residue and stains from the surface of the dishes, thus completing the initial cleaning of the dishes.

[0087] The first cleaning cycle performs a preliminary wash on all dishes, removing easily detachable residue and stains, effectively shortening the processing time of the subsequent second cleaning cycle. Because the second cleaning cycle cleans each dish more precisely in batches, pre-removing easily detachable residue and stains significantly reduces the workload of the second cleaning cycle. This ensures cleaning effectiveness while avoiding excessive processing time caused by multiple batches of fine washing, thus guaranteeing the dishwasher's efficiency.

[0088] In some embodiments, a turbidity sensor is also provided in the first cleaning zone. The turbidity of the wastewater generated from the first cleaning process is detected by the turbidity sensor, and the stain level of the tableware, such as light, medium, and heavy, is determined based on the detected turbidity peak. Then, the initial water pressure and detergent dosage of the second cleaning zone can be determined based on the stain level of the tableware.

[0089] like Figure 3 As shown, in some embodiments, the second cleaning zone 120 includes: a camera device 121 and a second cleaning device 122;

[0090] The camera device 121 is used to capture images of tableware in the second cleaning area 120;

[0091] The second cleaning device 122 is disposed on the side wall of the second cleaning area 120 and is used to rinse the tableware on the storage module 140 in the second cleaning area 120; the side wall of the second cleaning area 120 where the second cleaning device 122 is located is perpendicular to the extending direction of the first cleaning area 110 and the second cleaning area 120.

[0092] Figure 3 The gray area in the diagram represents the sidewall of the second cleaning zone, which is perpendicular to the extension direction of the first and second cleaning zones. In other words, it is the sidewall of the second cleaning zone where the second cleaning device is located.

[0093] It should be noted that, Figure 3 The diagram shows a flat layout of the sidewall of the second cleaning zone, where one of the second cleaning devices is located. This layout is only for visually illustrating the internal structure of the second cleaning zone and does not represent the actual spatial location of the sidewall. In the actual construction of the second cleaning zone, the sidewalls shown in gray areas are perpendicular to the bottom surface of the second cleaning zone.

[0094] It can be understood that if the extension directions of the first and second cleaning zones are taken as direction A, and the direction perpendicular to direction A is taken as direction B, then there are two sidewalls of the second cleaning zone in direction B, namely the sidewalls shown in the gray area.

[0095] In some embodiments, a camera device and a second cleaning device are provided on the sidewalls of the two gray areas.

[0096] As an example, the tableware is a dinner plate, and the front of the dinner plate faces the same direction when it is placed. Figure 3 The gray area represents the sidewall. In this case, both the camera device and the second cleaning device are mounted on the sidewall shown in the gray area. This allows for a more accurate determination of the locations of potential stains on the front and back of the plate based on the images of the tableware captured by the camera device. Furthermore, the water spray direction of the second cleaning device is controlled to more accurately rinse the stained areas, improving the cleaning effect of the tableware.

[0097] It is worth noting that, compared to placing the cleaning device at the top or bottom of the cleaning chamber for all-around rinsing, this embodiment of the invention places the second cleaning device at... Figure 3The gray area on the sidewall allows for targeted rinsing of stained areas, ensuring effective dishwashing while reducing wasted water and improving water utilization.

[0098] In some embodiments, the control device is specifically used for:

[0099] Based on the image of the tableware in the second cleaning area, determine the location of the stains on the tableware;

[0100] Control the second cleaning device to rinse the stained area.

[0101] As an example, after acquiring the tableware image, a computer vision analysis algorithm is used to analyze the image and identify the type and location of stains. Once the control board determines the stain type and location, it determines the water pressure of the second cleaning device based on the stain type and the spray direction based on the stain location.

[0102] It is understood that the second cleaning device includes a spray arm with adjustable water spray direction. The main control board controls the second cleaning device to adjust the water spray direction so that the water spray direction is aimed at the stain position, and then the stain position is rinsed with a determined water pressure.

[0103] In some embodiments, the washing surface of the tableware is determined, and the side of the second cleaning area facing the washing surface of the tableware is the side where the second cleaning device is located.

[0104] The cleaning surface of the tableware refers to the surface with the largest surface area. For example, the front (food-holding surface) and back (bottom contact surface) of a plate. The side of the second cleaning zone facing the cleaning surface of the tableware is the side where the second cleaning device is located, enabling the second cleaning device to clean the areas on the tableware most likely to have stains, thereby ensuring the cleaning effect of the second cleaning device on the tableware.

[0105] In some embodiments, the control device is specifically used for:

[0106] Determine the target storage module for each batch;

[0107] The target placement modules of each batch are controlled to move to the second cleaning area; the target placement modules of each batch do not obstruct each other in the rinsing direction.

[0108] During the process of controlling the movement of the storage modules in the first cleaning zone to the second cleaning zone in batches, it is necessary to determine the storage modules to be moved in each batch, and use these storage modules as target storage modules to control the movement of the target storage modules to the second cleaning zone.

[0109] Figures 4A to 4CThis is a schematic diagram of the distribution of a target placement module provided in an embodiment of the present invention.

[0110] Each batch of target storage modules does not obstruct each other in the rinsing direction. Combined Figure 3 It is understood that the direction in which the tableware faces is the rinsing direction of the second cleaning device. In this direction, each target placement module is not obstructed by other target placement modules.

[0111] The purpose of the second cleaning process in the second cleaning area is to thoroughly clean each piece of tableware, such as... Figure 4A As shown, if there are too many target placement modules in each batch, it will cause some of the target placement modules to be blocked in the rinsing direction. In this case, if there are stains on the blocked parts, the second cleaning device will have difficulty removing the stains, which will have a significant impact on the cleaning effect of the tableware.

[0112] like Figure 4B As shown, in some embodiments, only one placement module is designated as the target placement module for each batch, meaning that one target placement module is moved to the second cleaning area for the second cleaning process each time. In this case, it is guaranteed that there are no obstructions in the rinsing direction for each batch of target placement modules, thus ensuring the cleaning effect of the tableware.

[0113] However, if only one target placement module is moved to the second cleaning area for the second cleaning process in each batch, it will obviously lead to a significant increase in time and low cleaning efficiency. Therefore, while avoiding any obstruction of the target placement module in the rinsing direction, we consider increasing the number of target placement modules in each batch as much as possible.

[0114] In some embodiments, the quantity of target storage modules in each batch is determined based on the size information of the storage module and the size information of the second cleaning area. For example... Figure 4C As shown, the size of the second cleaning area is large enough to accommodate two storage modules that do not obstruct each other in the rinsing direction. Therefore, two storage modules are selected as target storage modules for each batch and moved to the second cleaning area for the second cleaning process.

[0115] In other embodiments, the number of target storage modules can be determined based on the actual dimensions of the storage module and the second cleaning area. In this embodiment of the invention, the number of target storage modules moved in each batch is not limited.

[0116] In some embodiments, it is also necessary to determine the position information of each target placement module in the second cleaning area based on the size information of the placement module and the size information of the second cleaning area, and control each target placement module to move to the corresponding position based on the position information, so as to ensure that the target placement modules do not block each other in the rinsing direction and ensure the cleaning effect of the tableware.

[0117] In practical applications, each storage module is connected to the control motherboard, and each storage module has a unique ID. The control motherboard can control the movement of the corresponding storage module based on the ID information of the storage module.

[0118] As an example, there are storage modules 1, 2, 3, 4, 5 and 6, on which tableware is placed and the first cleaning process is completed in the first cleaning area.

[0119] The control board determines the number of target placement modules to be moved in each batch based on the size information. If the number is 2, then the following order can be followed: First, placement modules 1 and 2 are identified as target placement modules, and they are moved to the second cleaning area to complete the second cleaning process. After the second cleaning process is completed, placement modules 1 and 2 are moved to the drying area. Second, placement modules 3 and 4 are identified as target placement modules, and they are moved to the second cleaning area to complete the second cleaning process. After the second cleaning process is completed, placement modules 3 and 4 are moved to the drying area. Third, placement modules 5 and 6 are identified as target placement modules, and they are moved to the second cleaning area to complete the second cleaning process. After the second cleaning process is completed, placement modules 5 and 6 are moved to the drying area. Thus, all tableware completes the second cleaning process.

[0120] In some embodiments, the storage module further includes a tableware detection device for determining whether tableware is placed on the storage module.

[0121] Before determining the target placement modules for each batch, the control board needs to identify all target placement modules that need to be moved to the second cleaning area. During this process, the tableware detection device identifies the target placement modules that need to be moved to the second cleaning area. If the tableware detection device determines that tableware is placed on the placement module, then the placement module is determined to be a target placement module and needs to be moved to the second cleaning area; if the tableware detection device determines that no tableware is placed on the placement module, then the placement module does not need to participate in the subsequent cleaning process, that is, it is not considered a target placement module.

[0122] As an example, a tableware detection device can be a weight detection device or an infrared detection device, etc.

[0123] In some embodiments, the control device is specifically used for:

[0124] During the second cleaning process, based on the image of the tableware, it is determined whether the tableware meets the conditions for completion of cleaning;

[0125] If the tableware meets the cleaning completion conditions, the second cleaning process ends, and the placement module in the second cleaning area is moved to the drying area.

[0126] During the second cleaning process, the second cleaning device is controlled to rinse the stained area for a preset time, such as 5 seconds. After rinsing, the rinsing is stopped and the latest image of the tableware is acquired again. The tableware is then judged to meet the cleaning completion conditions based on the latest image.

[0127] In practical applications, the image of the stained area on the tableware can be compared with a clean template using a difference analysis. When the similarity reaches 98%, the stain is considered cleaned. If the similarity does not reach 98%, the second cleaning device is controlled to rinse the stained area again, and the above steps are repeated until the stain is cleaned. Then, the second cleaning device is controlled to rinse the next stained area.

[0128] Once all stains on the tableware have been cleaned, the tableware is deemed to have met the cleaning completion criteria. When the tableware meets these criteria, the second cleaning process ends, and a movement command is sent to the placement modules in the second cleaning area, controlling them to move to the drying area. The next batch of placement modules is then moved to the second cleaning area, and the above process is repeated.

[0129] In some embodiments, a movable partition is provided between the second cleaning zone and the drying zone.

[0130] The partition is only opened when the storage module needs to be moved to the drying area. After the second cleaning process of the tableware is completed in the second cleaning area, the control board starts the partition according to the preset program, and then controls the storage module to move into the drying area. After the storage module moves into the drying area, the control board closes and resets.

[0131] On the one hand, when working in the second cleaning zone, the partition remains sealed, and the water vapor, detergent droplets and tiny stains generated by the high-pressure spray can be blocked in the second cleaning zone, effectively maintaining the dryness and cleanliness of the drying zone.

[0132] On the other hand, when all the tableware is moved to the drying zone, only the tableware itself needs to be dried. No additional energy is required to dry the first or second washing zone, thus improving drying efficiency and reducing the dishwasher's energy consumption. Furthermore, the sealing properties of the partitions optimize the heat circulation efficiency of the drying zone. By reducing ineffective heat diffusion to the first or second washing zone, the drying zone can maintain a more stable temperature. Combined with an infrared or hot air circulation system, this enables rapid drying of the tableware. This partition-based design further improves drying efficiency and maximizes energy utilization.

[0133] Figure 5 This is a flowchart of the steps of a dishwasher control method provided in an embodiment of the present invention.

[0134] like Figure 5 As shown, the method may specifically include the following steps:

[0135] Step 501: Control the multiple storage modules to remain in the first cleaning area to complete the first cleaning process;

[0136] In practical applications, the initial state is that the placement module is always in the first cleaning area. The user places the tableware to be cleaned in the placement module and starts the dishwasher, and the first cleaning process begins.

[0137] In some embodiments, the first cleaning area includes: a first cleaning device; the first cleaning device is disposed at the top of the first cleaning area and is used to perform a first cleaning process on the tableware on the storage module in the first cleaning area.

[0138] It is understandable that in actual application scenarios, the initial working state of the dishwasher is that all the placement modules are in the first cleaning zone. After the user places the dishes to be cleaned in the placement modules and starts the dishwasher, the control module controls the first cleaning device to perform the first cleaning process on all the dishes to be cleaned in the first cleaning zone.

[0139] As an example, the control module controls the first cleaning device to generate a high-pressure fan-shaped water curtain to rinse the tableware to be cleaned in the first cleaning zone. The high-pressure fan-shaped water curtain can remove easily detachable residue and stains from the surface of the tableware, thus completing the initial cleaning of the tableware.

[0140] The first cleaning cycle performs a preliminary wash on all dishes, removing easily detachable residue and stains, effectively shortening the processing time of the subsequent second cleaning cycle. Because the second cleaning cycle cleans each dish more precisely in batches, pre-removing easily detachable residue and stains significantly reduces the workload of the second cleaning cycle. This ensures cleaning effectiveness while avoiding excessive processing time caused by multiple batches of fine washing, thus guaranteeing the dishwasher's efficiency.

[0141] In some embodiments, a turbidity sensor is also provided in the first cleaning zone. The turbidity of the wastewater generated from the first cleaning process is detected by the turbidity sensor, and the stain level of the tableware, such as light, medium, and heavy, is determined based on the detected turbidity peak. Then, the initial water pressure and detergent dosage of the second cleaning zone can be determined based on the stain level of the tableware.

[0142] Step 502: After the first cleaning process, repeat the following steps: control the placement modules in the first cleaning area to move to the second cleaning area in batches to complete the second cleaning process; after the second cleaning process, control the placement modules in the second cleaning area to move to the drying area until all the tableware has been moved to the drying area to complete the drying process.

[0143] The dishwasher is divided into a first cleaning zone, a second cleaning zone, and a drying zone, connected sequentially. Multiple movable storage modules allow for the movement of dishes within these zones. After being washed uniformly in the first cleaning zone, dishes are moved in batches to the second cleaning zone for further washing. This second washing, especially when dishes are placed in low density, improves cleaning effectiveness and enhances the user experience. Furthermore, after washing, all dishes are moved to the drying zone. The drying process only requires drying the dishes themselves, eliminating the need to consume energy to dry the areas in the first or second cleaning zones. This improves drying efficiency, shortens drying time, and further enhances the user experience.

[0144] In some embodiments, the second cleaning area includes: a camera device and a second cleaning device; the camera device is used to capture images of tableware in the second cleaning area; the second cleaning device is disposed on the side wall of the second cleaning area and is used to rinse the tableware on the storage module in the second cleaning area; the side wall of the second cleaning area where the second cleaning device is located is perpendicular to the extending direction of the first cleaning area and the second cleaning area;

[0145] In some embodiments, step 502 specifically includes the following sub-steps:

[0146] Sub-step S11: Obtain an image of the tableware in the second cleaning area; determine the location of the stains on the tableware based on the tableware image; control the second cleaning device to rinse the stain locations.

[0147] As an example, the tableware is a dinner plate, and the front of the dinner plate faces the same direction when it is placed. Figure 3 The gray area represents the sidewall. In this case, both the camera device and the second cleaning device are mounted on the sidewall shown in the gray area. This allows for a more accurate determination of the locations of potential stains on the front and back of the plate based on the images of the tableware captured by the camera device. Furthermore, the water spray direction of the second cleaning device is controlled to more accurately rinse the stained areas, improving the cleaning effect of the tableware.

[0148] After acquiring the tableware images, computer vision analysis algorithms are used to analyze the images and identify the types and locations of stains. Once the control board determines the stain type and location, it determines the water pressure of the second cleaning device based on the stain type and the spray direction based on the stain location.

[0149] It is understood that the second cleaning device includes a spray arm with adjustable water spray direction. The main control board controls the second cleaning device to adjust the water spray direction so that the water spray direction is aimed at the stain position, and then the stain position is rinsed with a determined water pressure.

[0150] In some embodiments, it is also necessary to determine the washing surface of the tableware and ensure that the side of the second cleaning area facing the washing surface of the tableware is the side where the second cleaning device is located.

[0151] The cleaning surface of the tableware refers to the surface with the largest surface area. For example, the front (food-holding surface) and back (bottom contact surface) of a plate. The side of the second cleaning zone facing the cleaning surface of the tableware is the side where the second cleaning device is located, enabling the second cleaning device to clean the areas on the tableware most likely to have stains, thereby ensuring the cleaning effect of the second cleaning device on the tableware.

[0152] In some embodiments, step 502 specifically includes the following sub-steps:

[0153] Sub-step S21: Determine the target placement module for each batch;

[0154] It is understandable that the purpose of the second cleaning process in the second cleaning area is to perform a thorough cleaning of each piece of tableware, such as... Figure 4A As shown, if there are too many target storage modules in each batch, and the target storage modules are obstructed in the rinsing direction, the stained areas may be blocked, which will have a significant impact on the cleaning effect.

[0155] like Figure 4B As shown, in some embodiments, only one placement module is designated as the target placement module for each batch, meaning that one target placement module is moved to the second cleaning area for the second cleaning process each time. In this case, it is guaranteed that the target placement modules of each batch will not obstruct each other in the rinsing direction, thus ensuring the cleaning effect of the tableware.

[0156] However, if only one target placement module is moved to the second cleaning area for the second cleaning process in each batch, the cleaning efficiency is obviously low. Therefore, while avoiding obstruction of the target placement modules in the rinsing direction, the number of target placement modules in each batch should be increased as much as possible.

[0157] In some embodiments, the quantity of target storage modules in each batch is determined based on the size information of the storage module and the size information of the second cleaning area. For example... Figure 4C As shown, the size of the second cleaning area is large enough to accommodate two storage modules that do not obstruct each other in the rinsing direction. Therefore, two storage modules are selected as target storage modules for each batch and moved to the second cleaning area for the second cleaning process.

[0158] In other embodiments, the number of target storage modules can be determined based on the actual dimensions of the storage module and the second cleaning area. In this embodiment of the invention, the number of target storage modules moved in each batch is not limited.

[0159] Sub-step S22: Control each batch of target placement modules to move to the second cleaning area; the target placement modules of each batch do not obstruct each other in the rinsing direction.

[0160] In practical applications, each storage module is connected to the control motherboard, and each storage module has a unique ID. The control motherboard can control the movement of the corresponding storage module based on the ID information of the storage module.

[0161] As an example, there are storage modules 1, 2, 3, 4, 5 and 6, on which tableware is placed and the first cleaning process is completed in the first cleaning area.

[0162] The control board determines the number of target placement modules to be moved in each batch based on the size information. If the number is 2, then the following order can be followed: First, placement modules 1 and 2 are identified as target placement modules, and they are moved to the second cleaning area to complete the second cleaning process. After the second cleaning process is completed, placement modules 1 and 2 are moved to the drying area. Second, placement modules 3 and 4 are identified as target placement modules, and they are moved to the second cleaning area to complete the second cleaning process. After the second cleaning process is completed, placement modules 3 and 4 are moved to the drying area. Third, placement modules 5 and 6 are identified as target placement modules, and they are moved to the second cleaning area to complete the second cleaning process. After the second cleaning process is completed, placement modules 5 and 6 are moved to the drying area. Thus, all tableware completes the second cleaning process.

[0163] In some embodiments, the storage module further includes a tableware detection device for determining whether tableware is placed on the storage module.

[0164] In some embodiments, the method further includes: before determining each batch of target placement modules, the control board needs to determine all target placement modules that need to be moved to the second cleaning area.

[0165] During this process, the tableware detection device determines the target placement module that needs to be moved to the second cleaning area. If the tableware detection device determines that tableware is placed on the placement module, it determines that the placement module is the target placement module and needs to be moved to the second cleaning area. If the tableware detection device determines that no tableware is placed on the placement module, it determines that the placement module does not need to participate in the subsequent cleaning process, that is, it does not consider the placement module as the target placement module.

[0166] As an example, a tableware detection device can be a weight detection device or an infrared detection device, etc.

[0167] In some embodiments, step 502 specifically includes the following sub-steps:

[0168] Sub-step S31: In the second cleaning process, based on the tableware image, determine whether the tableware meets the cleaning completion conditions;

[0169] During the second cleaning process, the second cleaning device is controlled to rinse the stained area for a preset time, such as 5 seconds. After rinsing, the rinsing is stopped and the latest image of the tableware is acquired again. The tableware is then judged to meet the cleaning completion conditions based on the latest image.

[0170] As an example, in practical applications, the image of the stained area on the tableware can be compared with a clean template using a difference analysis. When the similarity reaches 98%, it is determined that the stained area has been cleaned. If the similarity does not reach 98%, the second cleaning device is controlled to rinse the stained area again, and the above steps are repeated until the stained area is cleaned. Then, the second cleaning device is controlled to rinse the next stained area.

[0171] In sub-step S32, if the tableware meets the cleaning completion condition, the second cleaning process ends, and the placement module in the second cleaning area is moved to the drying area.

[0172] Once all stains on the tableware have been cleaned, the tableware is deemed to have met the cleaning completion criteria. When the tableware meets these criteria, the second cleaning process ends, and a movement command is sent to the placement modules in the second cleaning area, controlling them to move to the drying area. The next batch of placement modules is then moved to the second cleaning area, and the above process is repeated.

[0173] In some embodiments, a movable partition is provided between the second washing zone and the drying zone. The partition is only opened when it is necessary to move the placement module to the drying zone. After the second washing process of the tableware is completed in the second washing zone, the control board starts the partition according to a preset program, and then controls the placement module to move into the drying zone. After the placement module moves into the drying zone, the control board closes and resets the partition.

[0174] On the one hand, when working in the second cleaning zone, the partition remains sealed, and the water vapor, detergent droplets and tiny stains generated by the high-pressure spray can be blocked in the second cleaning zone, effectively maintaining the dryness and cleanliness of the drying zone.

[0175] On the other hand, when all the tableware is moved to the drying zone, only the tableware itself needs to be dried. No additional energy is required to dry the first or second washing zone, thus improving drying efficiency and reducing the dishwasher's energy consumption. Furthermore, the sealing properties of the partitions optimize the heat circulation efficiency of the drying zone. By reducing ineffective heat diffusion to the first or second washing zone, the drying zone can maintain a more stable temperature. Combined with an infrared or hot air circulation system, this enables rapid drying of the tableware. This partition-based design further improves drying efficiency and maximizes energy utilization.

[0176] This invention divides the dishwasher into a first cleaning zone, a second cleaning zone, and a drying zone connected sequentially, and incorporates multiple movable storage modules to allow for the movement of tableware across these zones. After being washed uniformly in the first cleaning zone, the tableware is then moved in batches to the second cleaning zone for further washing. This batch washing method reduces the density of the tableware, thereby improving the cleaning effect and enhancing the user experience. Furthermore, after washing, all tableware is moved to the drying zone for drying. Since the drying zone is free of moisture and residue from washing, the drying environment is drier and cleaner, improving drying efficiency and effectiveness, further enhancing the user experience.
