Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a dishwasher control method, apparatus, dishwasher equipment, and computer-readable storage medium. Background Technology

[0002] With the development of technology and the improvement of people's living standards, dishwashers have gradually entered thousands of households and are widely used. Compared with traditional manual dishwashing, dishwashers have stronger cleaning power, effectively removing stubborn grease and food residue. They are also easy to operate, requiring only simple settings to complete the washing process, truly achieving the convenient experience of "freeing up hands" and thus greatly improving the quality of family life.

[0003] However, in actual daily use, the number of dishes that users need to wash may be far less than the dishwasher's capacity (for example, if a user's family consists of 1-2 people, the actual number of dish sets that need to be washed is less than the dishwasher's rated capacity). In this case, the dishwasher will still wash according to the rated capacity, which will result in a waste of water and electricity and is not conducive to resource conservation. Summary of the Invention

[0004] Therefore, it is necessary to provide a dishwasher control method, device, washing equipment, computer-readable storage medium, and computer program product that can make dishwashers more energy-efficient and environmentally friendly, in response to the above-mentioned technical problems.

[0005] In a first aspect, this application provides a dishwasher control method, including:

[0006] In response to a cleaning command, the dishwasher acquires detection data corresponding to each layer of the container assembly, and determines the soiling status of the tableware in each layer of the container assembly based on the detection data; the dishwasher includes multiple layers of the container assembly, which are used to store tableware.

[0017] In one embodiment, the method further includes:

[0018] If the tableware in the receiving component is in a stained state, the level of soiling of the tableware in the receiving component is determined.

[0020] In one embodiment, after obtaining the soiling status of the tableware in each layer of the receiving assembly, the method further includes:

[0021] If, based on the state of soiling, it is determined that there are no soiled tableware in the container components of each layer, a corresponding prompt signal is output.

[0022] In one embodiment, after outputting the corresponding prompt signal, the method further includes:

[0023] In response to a confirmed cleaning command, the cleaning device is controlled to operate in a full-layer washing mode; in the full-layer washing mode, the cleaning device cleans the tableware in each of the receiving components.

[0024] Secondly, this application also provides a dishwasher control device, comprising:

[0025] A status determination module is used to respond to a cleaning command, acquire detection data corresponding to each layer of the receiving components, and determine the soiling status of the tableware in each layer of the receiving components based on the detection data; the dishwasher includes multiple layers of the receiving components, which are used to store tableware;

[0026] A soiling detection module is used to determine, based on the soiling status, the target container component in each layer of the container components that holds soiled tableware;

[0027] A cleaning control module is used to control the cleaning device of the dishwasher to operate in a layered washing mode; in the layered washing mode, the cleaning device cleans the tableware in the target containment components; each layer of the containment components is located within the cleaning range of the cleaning device.

[0028] Thirdly, this application also provides a dishwasher, including a dishwasher, a controller, and a detection device.

The controller is used to control the dishwasher according to the method described above.

[0029] In one embodiment, the dishwasher further includes a washing chamber and a water cup, and the detection device is a turbidity detection device; each of the receiving components and the cleaning device is disposed in the washing chamber, and the water cup is disposed at the bottom of the washing chamber; the turbidity detection device is disposed in the water cup, and the turbidity detection device is electrically connected to the controller.

[0031] In response to a cleaning command, the dishwasher acquires detection data corresponding to each layer of the container assembly, and determines the soiling status of the tableware in each layer of the container assembly based on the detection data; the dishwasher includes multiple layers of the container assembly, which are used to store tableware.

The dishwasher includes multiple layers of receiving components for storing tableware. Based on the soiling status, the target receiving component for storing soiled tableware is determined among the receiving components. The dishwasher's cleaning device is controlled to operate in a layered washing mode. In the layered washing mode, the cleaning device cleans the tableware in the target receiving component. Each layer of the receiving components is within the cleaning range of the cleaning device. Therefore, by acquiring the soiling status of the tableware in each layer of the receiving components, the target receiving component that actually needs cleaning can be accurately located, and the cleaning device can be controlled to operate in a layered washing mode, specifically cleaning the layers with soiled tableware and ignoring the layers without soiled tableware. This effectively avoids the waste of water and electricity caused by traditional dishwashers running at the rated number of sets when the number of tableware is small, significantly improving energy efficiency and making the dishwasher more energy-saving and environmentally friendly.

[0046] Figure 7 This is a structural block diagram of a dishwasher control device in one embodiment. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] The dishwasher control method provided in this application can be applied to dishwasher equipment. In some embodiments, such as Figure 1 As shown, the dishwasher includes a dishwasher 102 and a controller 104. The dishwasher 102 includes a multi-layer holding assembly and a cleaning device. The holding assembly is used to store tableware, and the number of layers and the capacity of each layer can be flexibly set according to actual usage needs and installation space. The layered design helps to make efficient use of space and improve the efficiency and stability of tableware placement. In some embodiments, the holding assembly is a bowl basket, specifically a two-layer structure: an upper bowl basket and a lower bowl basket. The upper bowl basket can be used to place smaller, lighter tableware, such as small bowls, cups, and condiment plates, while the lower bowl basket can hold larger, heavier tableware, such as large bowls and pots.

[0049] The cleaning device is electrically connected to the controller 104. Each layer of the receiving components is located within the cleaning range of the cleaning device, which is used to clean various types of tableware placed in the receiving components. In some embodiments, the cleaning device includes a spray assembly electrically connected to the controller 104. Under the control of the controller 104, the spray assembly can spray high-pressure water jets from multiple angles to powerfully rinse the tableware placed in the receiving components, effectively removing food residue and stains from the tableware.

[0050] In some embodiments, the cleaning device includes multiple sets of spraying components. Specifically, each spraying component is arranged in a one-to-one correspondence with a receiving component, that is, each set of spraying components independently sprays a layer of tableware in the receiving component to achieve layered cleaning of the tableware. The structure of the spraying components is not limited, for example, a spraying arm or other forms can be used.

[0051] It's understandable that the washing unit can include more components depending on the specific needs, such as a water pump assembly, a heating assembly, and a dispenser. The water pump assembly ensures a stable and continuous flow of water to the spray assembly, maintaining consistent rinsing pressure. The heating assembly heats the water entering the dishwasher; the high-temperature water not only dissolves grease on dishes more effectively but also sterilizes and disinfects. The dispenser dispenses detergent according to a preset program, further enhancing the washing effect.

[0052] In some embodiments, the dishwasher further includes a detection device electrically connected to the controller 104, the controller 104 acquiring detection data from the detection device to determine the soiling status of the tableware in each layer of the receiving assembly. In some embodiments, the detection device may be a sensor specifically designed for detecting the soiling status of the tableware, such as an image sensor, an odor sensor, an ultrasonic sensor, etc., and the controller determines the soiling status of the tableware in each layer of the receiving assembly based on the detection data from the image sensor, odor sensor, or ultrasonic sensor.

[0053] In some optional embodiments, the detection device reuses the existing turbidity detection device in the dishwasher. During dishwasher operation, the water flow carries dirt from the surface of the dishes as it rinses them, causing the water flow to exhibit different levels of turbidity. The turbidity detection device can detect the turbidity parameters corresponding to the dishes in each layer of the container and transmit them to the controller 104. The controller 104 determines the soiling status of the dishes in each layer of the container based on the corresponding turbidity parameters. Therefore, there is no need to set up additional sensors (such as image sensors) or other detection devices specifically for detecting the soiling status of the dishes; the existing turbidity detection device can be directly utilized, allowing the dishwasher to maintain complete functionality while effectively controlling the cost.

[0054] Furthermore, in some embodiments, the dishwasher also includes a washing chamber and a water cup. All the accommodating components and cleaning devices are disposed within the washing chamber, which provides a stable space for cleaning and storing the tableware. Depending on actual needs, the washing chamber can be configured as a closed or open chamber. The accommodating components within the washing chamber can be physically separated by partitions, or other methods of separation can be used; this embodiment does not limit this approach.

[0055] The water cup, located at the bottom of the washing chamber, plays a crucial role in collecting and temporarily storing wash water. A turbidity detection device can be placed inside the water cup. When wash water containing stains from various layers of tableware flows into the cup, the device accurately detects the turbidity parameters corresponding to the tableware in each layer of the container. This layout facilitates the natural collection of wash water, allows for accurate turbidity detection, and also streamlines subsequent drainage, making the dishwashing process smoother and more efficient.

[0056] In other embodiments, the dishwasher also includes a turbidity detection chamber, which is connected to the washing chamber. Specifically, the washing chamber is connected to the turbidity detection chamber via a water cup at the bottom. A turbidity detection device is located within the turbidity detection chamber. Therefore, by providing a turbidity detection chamber independent of the dishwasher's washing chamber, water from the washing chamber can be introduced into the turbidity detection chamber for detection. This mitigates the impact of interference factors such as water wave vibration, detergent residue obstruction, and air bubbles during dishwasher operation on turbidity detection, effectively improving the accuracy and stability of turbidity detection.

[0057] The controller 104 is used to respond to the cleaning command, acquire the detection data corresponding to each layer of the container, and determine the soiling status of the tableware in each layer of the container based on the detection data; the dishwasher includes multiple layers of container, which are used to store tableware; the controller determines the target container in each layer of the container to store soiled tableware based on the soiling status; the controller controls the cleaning device of the dishwasher to operate in a layered washing mode; in the layered washing mode, the cleaning device cleans the tableware in the target container; each layer of the container is located within the cleaning range of the cleaning device.

[0058] In one exemplary embodiment, such as Figure 2 As shown, a dishwasher control method is provided, which is applied to... Figure 1 The following steps are used as an example to illustrate the process, taking controller 104 as an example: Steps 202 to 206. Wherein:

[0059] Step 202: In response to the cleaning command, acquire the detection data corresponding to each layer of the container component, and determine the dirt status of the tableware in each layer of the container component based on the detection data.

[0060] Dishwashers include multiple layers of containers for storing tableware, and the specific number of layers can be set according to actual needs, such as two, three, or four layers.

[0061] The dishwasher is also equipped with an operation panel or communication module that connects to the controller. The controller establishes a connection with the user's smart terminal (such as a mobile phone, tablet, wearable device, etc.) through the communication module. After the user puts the dishes to be washed into the corresponding container, they can trigger the cleaning command through the operation panel or smart terminal.

[0062] The soiled state can include both stained and clean states that do not require washing. The detection data for each layer of the container will vary depending on the specific type of detection device. For example, when the detection device uses an odor sensor, if a user places stained tableware into the same layer (assuming the layer's rated capacity is 8 sets, and the number of stained tableware sets is less than or equal to 8 sets), the odor in that layer will significantly increase. The controller will then determine that the tableware in that layer is stained based on the data from the odor sensor. Conversely, if the user does not place any tableware into a particular layer, or if clean tableware is placed there, the odor change is not significant, and the controller will determine that the tableware in that layer is clean based on the data from the odor sensor.

[0063] Step 204: Determine the target container for storing soiled tableware in each layer of container based on the soiling status.

[0064] Specifically, after determining whether the tableware in each layer of the container is in a state of dirt that needs to be washed or a state of cleanliness that does not need to be washed, the controller identifies the container containing the tableware in the state of dirt as the target container, and the layer where the target container is located is the target cleaning layer.

[0065] In this embodiment, all containers including stained tableware are considered as target containers. Regardless of the proportion of clean tableware in the layer, the entire layer is considered as the cleaning target as long as there is stained tableware.

[0066] Step 206: Control the dishwasher's cleaning device to operate in a layered washing mode; in the layered washing mode, the cleaning device cleans the dishes in the target container.

[0067] Once the controller has determined the soiling status of the tableware in each shelf and identified the target shelf, it controls the dishwasher's cleaning unit to operate in a layered washing mode. Taking a dishwasher with three shelves as an example, assuming steps 202 and 204 identify the second and third shelves as the target shelves (i.e., shelves containing soiled tableware), the controller sends a command to the cleaning unit to activate the layered washing mode. In this mode, the cleaning unit specifically cleans the tableware in the second and third shelves. For example, the spray arms adjust the angle and intensity of the spray to rinse the tableware in the second and third shelves, avoiding unnecessary cleaning of the clean tableware in the first shelf. Simultaneously, other components working in conjunction with the cleaning unit, such as the water pump, heating element, and dispenser, also work together to provide suitable water temperature, water pressure, and detergent conditions for cleaning the target shelves, ensuring thorough and effective cleaning of the tableware and achieving precise layered washing.

[0068] The aforementioned dishwasher control method, in response to a cleaning command, acquires the soiling status of the tableware in each layer of the receiving unit. The dishwasher includes multiple layers of receiving units for storing tableware. Based on the soiling status, the target receiving unit for storing soiled tableware is determined within each layer. The dishwasher's cleaning device is controlled to operate in a layered washing mode. In this layered washing mode, the cleaning device cleans the tableware in the target receiving unit. Each receiving unit is within the cleaning range of the cleaning device. Therefore, by acquiring the soiling status of the tableware in each receiving unit, the target receiving unit that actually needs cleaning can be accurately located, and the cleaning device can be controlled to operate in a layered washing mode, specifically cleaning the layers with soiled tableware and ignoring layers without soiled tableware. This effectively avoids the waste of water and electricity caused by traditional dishwashers running at the rated load capacity when the number of tableware is small, significantly improving energy efficiency and making the dishwasher more energy-saving and environmentally friendly. Moreover, the controller can locate the target receiving unit that actually needs cleaning, eliminating the need for the user to manually input the target layer, thus avoiding unsuccessful washing and wasted water and electricity due to user input errors, thereby improving the reliability and intelligence of the dishwasher.

[0069] In some embodiments, such as Figure 3 As shown, the steps involve acquiring detection data corresponding to each layer of the container assembly, and determining the soiling status of the tableware in each layer of the container assembly based on the detection data, including steps 302 to 306. Wherein:

[0070] Step 302: Control the cleaning device to operate in pre-wash mode.

[0071] In the pre-wash mode, the spray components in the cleaning device spray the tableware in each layer of the container in turn.

[0072] Specifically, when a user triggers a cleaning command via the control panel or smart terminal, the controller immediately sends a command to the cleaning device, instructing it to enter pre-wash mode. In pre-wash mode, the spray components in the cleaning device spray the dishes in each of the designated compartments in a preset order. For example, if the dishwasher has upper and lower compartments and corresponding spray components, the controller will control the upper spray component to spray the dishes in the upper compartment first. After completing the upper spray, the controller will control the lower spray component to spray the dishes in the lower compartment.

[0073] In some embodiments, during the pre-wash mode, the spraying time for the dishes in each of the receiving assemblies is a preset pre-wash duration. Taking a dishwasher with upper and lower receiving assemblies and corresponding spraying assemblies as an example, the controller controls the upper spraying assembly to spray the dishes in the upper receiving assembly for the preset pre-wash duration. Then, the controller controls the lower spraying assembly to spray the dishes in the lower receiving assembly for the preset pre-wash duration. This preset pre-wash duration can be set based on actual experiments and experience, for example, set to 2 minutes, to ensure that easily detachable stains on the surface of the dishes are initially rinsed away.

[0074] Step 304: After obtaining the tableware in each layer of the spray container, obtain the turbidity parameters of the liquid to be discharged.

[0075] After each layer of the container completes its pre-wash spraying, the wastewater generated from the sprayed tableware, i.e., the liquid to be discharged, flows into the water cup. At this time, a turbidity detection device (such as a turbidity sensor) installed in the water cup or turbidity detection chamber will detect the turbidity of the wastewater in real time and transmit the detected turbidity data to the controller 104. For example, for the wastewater to be discharged after the pre-washing of the upper layer of tableware, the turbidity sensor will acquire its turbidity parameter and feed it back to the controller; similarly, the turbidity parameter of the wastewater to be discharged after the pre-washing of the lower layer of tableware will also be acquired and transmitted to the controller.

[0076] Step 306: Determine the soiling status of the tableware in each layer of the container based on each turbidity parameter.

[0077] After receiving the turbidity parameters of the liquid to be discharged after pre-washing each layer of the container, the controller compares them with a preset turbidity threshold to distinguish whether the tableware is in a stained or clean state. If the turbidity parameter of the liquid to be discharged after pre-washing a certain layer of the container is high, it indicates that there are more stains on the surface of the tableware in that layer. In this case, the controller determines that the tableware in that layer of the container is in a stained state and needs to be cleaned in the subsequent formal cleaning.

[0078] In this embodiment, by acquiring the turbidity parameters of the liquid to be discharged after spraying each layer of tableware in the pre-wash mode, the soiling status of the tableware in each layer's container can be accurately and efficiently determined based on the corresponding turbidity parameters of each layer. This provides a reliable basis for subsequent layered washing and improves the reliability of the dishwasher's layered washing control. Moreover, this method of providing a layered washing basis using the detection data from the dishwasher's original turbidity detection device does not require additional sensors, and can effectively control the dishwasher's cost while improving its efficiency.

[0079] In some embodiments, step 306 includes the following steps:

[0080] If the turbidity parameter is greater than or equal to the preset turbidity threshold, the dirty state of the tableware in the container is determined to be a stain state.

[0081] The preset turbidity threshold can be determined experimentally. For example, researchers fill each shelf with clean tableware, then put the dishwasher into a pre-wash mode, causing the spray unit to sequentially spray the clean tableware in each shelf. During and after spraying, a turbidity detection device accurately measures the turbidity of the liquid to be discharged after spraying each shelf. These turbidity data obtained from multiple experiments are then comprehensively analyzed, statistically analyzed, and calculated—for example, by taking an average value and considering a certain error range—to determine a reasonable preset turbidity threshold.

[0082] If the turbidity parameter of a certain layer of the container is greater than or equal to the preset turbidity threshold, it indicates that during the pre-washing process, a lot of stains were washed off the tableware in that layer of the container, resulting in a high turbidity of the liquid to be discharged. It can be determined that the tableware in this container is in a stained state and needs to be cleaned more thoroughly in the future.

[0083] It is understandable that when the turbidity parameter is less than the preset turbidity threshold, the dirty state of the tableware in the container is determined to be clean.

[0084] If the turbidity parameter is less than the preset turbidity threshold, it indicates that less dirt was washed off the tableware in this layer during the pre-washing, and the liquid to be discharged is relatively clear. Therefore, it is determined that the tableware in this layer of the container is in a clean state and no subsequent main washing operation is required.

[0085] In some embodiments, considering that different layers of the container may differ due to factors such as the type, quantity, and frequency of use of the tableware, a corresponding preset turbidity threshold can be set for each layer. After obtaining the turbidity parameters corresponding to each layer, the turbidity parameters of each layer are compared with their corresponding preset turbidity thresholds to more accurately determine the soiling status of the tableware in each layer. This provides a more targeted basis for subsequent layered washing, further improving the cleaning efficiency and effectiveness of the dishwasher.

[0086] Further, step 204 includes the following steps:

[0087] If the tableware in the container is in a soiled state, the container is determined to be the target container for storing the soiled tableware.

[0088] When the tableware in the receiving unit is in a soiled state, it indicates that at least some of the tableware in that layer has stains (such as food residue, grease, etc.) on its surface that need to be cleaned and removed. At this time, the controller accurately identifies this receiving unit as the target receiving unit for storing soiled tableware, ensuring that only receiving units with truly soiled tableware are included in the cleaning range, effectively improving the dishwasher's resource utilization efficiency and intelligence.

[0089] In some embodiments, such as Figure 4 As shown, the dishwasher control method further includes steps 402 and 404.

[0090] Step 402: If the tableware in the receiving component is in a stained state, determine the level of dirtiness of the tableware in the receiving component.

[0091] In this embodiment, after the controller determines that the tableware in one or more layers of the container is stained, it further determines the level of soiling based on the detection data from the detection device. Specifically, the controller assesses the soiling level of the tableware based on a preset soiling degree classification standard, combined with the detection data obtained during the pre-washing stage (such as the turbidity parameter of the liquid to be discharged). For example, the soiling level is divided into three levels: light soiling, moderate soiling, and heavy soiling. If the turbidity parameter of the discharged liquid is slightly higher than the preset turbidity threshold, the tableware in that layer may be judged as lightly soiled; if the turbidity parameter is significantly higher than the preset turbidity threshold, it is judged as moderately soiled; and when the turbidity parameter far exceeds the preset turbidity threshold, the tableware in that layer is determined to be heavily soiled.

[0092] Step 404: Determine the initial washing parameters corresponding to the layered washing mode based on the level of soiling.

[0093] After determining the level of soiling of the tableware in each layer of the dishwasher, the controller determines the corresponding initial washing parameters based on the different levels of soiling. Then, based on these initial washing parameters, the controller operates the dishwasher's cleaning unit in a layered washing mode. The initial washing parameters control the initial operating state of the cleaning unit when it runs in layered washing mode. These washing parameters can be set according to actual conditions, and may include, for example, water temperature, water pressure, washing time, spray angle, and detergent dosage.

[0094] In this embodiment, by accurately determining the initial washing parameters based on the level of dirt, the dishwasher can provide suitable initial cleaning conditions for dishes with different levels of dirt in the layered washing mode, thereby improving the cleaning effect and efficiency.

[0095] In some embodiments, during the layered washing process, the controller continuously monitors the real-time turbidity through a turbidity detection device and adjusts the washing parameters based on the real-time turbidity. The controller then controls the washing device based on these adjusted parameters. This allows the dishwasher to adjust the washing parameters in real-time and precisely according to the actual cleaning condition of each layer of dishes during the layered washing process. This ensures that each layer of dishes receives a cleaning appropriate for its level of soiling, thereby improving the dishwasher's cleaning effect and mitigating problems such as incomplete cleaning of some dishes or energy waste caused by fixed washing parameters. This makes the dishwasher more reliable and energy-efficient.

[0096] In some embodiments, such as Figure 5 As shown, after step 202, the dishwasher control method further includes the following step 502.

[0097] Step 502: If it is determined that there are no dirty tableware in each layer of the container based on the state of dirt, output the corresponding prompt signal.

[0098] Specifically, when the controller determines that the tableware in each layer of the container is in a clean state, i.e., there is no dirty tableware, based on the state of dirtiness of the tableware in each layer of the container, the controller will trigger the prompt signal output module to output the corresponding prompt signal.

[0099] The prompt signal output module can be configured according to actual needs. For example, it can be a display screen, with the controller controlling the screen to display corresponding prompt information, such as "After testing, all layers of tableware are clean and do not require washing." The prompt signal output module can also be a voice prompt module, with the controller controlling the voice prompt module to broadcast corresponding voice prompt information. Alternatively, the prompt signal output module can be a user terminal device, with the controller sending prompt information to the user terminal device for the terminal device to provide the prompt to the user.

[0100] In this embodiment, after obtaining the soiling status of the tableware in each layer of the dishwasher, if it is determined based on the soiling status that there are no soiled tableware in each layer of the dishwasher, the subsequent cleaning operation will not be initiated. Instead, a corresponding prompt signal will be output so that the user can be informed of the soiling status of each piece of tableware. This avoids the user starting unnecessary cleaning programs without knowing the actual soiling status of the tableware in the dishwasher, further saving water and electricity resources.

[0101] In some embodiments, such as Figure 6 As shown, after step 502, the dishwasher control method further includes the following step 602.

[0102] Step 602: In response to the confirmed cleaning command, control the cleaning device to operate in full-layer washing mode.

[0103] In full-layer washing mode, the washing device cleans the tableware in each of the holding components.

[0104] In this embodiment, if a prompt indicating that cleaning is not required is issued, and the controller detects that the user has issued a confirmation cleaning command, it will control the cleaning device to operate in full-layer washing mode. The method by which the user issues the confirmation cleaning command is not required, such as triggering the cleaning command again via the control panel or smart terminal.

[0105] Therefore, when all the dishes in the dishwasher are clean, but the user still needs to clean them, the dishwasher will use a full-layer washing mode to thoroughly clean the dishes in each layer of the container, thus meeting the user's cleaning needs and improving the convenience of using the dishwasher.

[0106] To better understand the above embodiments, an optional embodiment will be explained in detail below. In one embodiment, the receiving component is a dish rack, the spraying component is a spraying arm, the dishwasher includes upper and lower dish racks, and the cleaning device includes upper and lower spraying arms corresponding to the upper and lower dish racks.

[0107] In pre-wash mode, the spray arms corresponding to different rack layers operate independently to obtain pre-wash water for each layer. A turbidity sensor installed inside the water cup detects the turbidity of the water during the pre-wash stage of each rack layer and transmits the results to the controller. The controller compares the turbidity of the pre-wash water for each rack layer with a preset turbidity threshold to determine which rack layer contains soiled dishes. It then controls the spray arms to operate during the main wash stage, specifically cleaning the target rack containing the soiled dishes.

[0108] Specifically, after the user places the dishes and closes the dishwasher door, and issues a cleaning command, the controller responds and enters the pre-wash program. During the pre-wash stage, the upper spray arm is first controlled to run for a preset pre-wash time. After the pre-wash is completed, the turbidity sensor in the water cup detects the turbidity of the wash water in the upper basket. If the turbidity is greater than or equal to a preset turbidity threshold, it is determined that the dishes in the upper basket are dirty, and the upper basket becomes the target container. If the turbidity is less than the preset turbidity threshold, it is determined that the dishes in the upper basket are not dirty, and the wash water is drained after the determination is completed. The same logic is applied to the lower basket before the wash water is drained.

[0109] The controller will determine which racks' spray arms to operate during the main wash phase based on the judgment result. If the judgment result is that all the dishes on all racks are clean, the control module will send a prompt message to remind the user that there are no dishes that need to be washed, and ask the user to confirm whether to continue starting the dishwasher to avoid wasting water and electricity.

[0110] The dishwasher control method described above eliminates the need for users to select the wrong shelf area after placing the dishes, and also eliminates the need for manual settings, thus improving the dishwasher's intelligence and energy efficiency.

[0111] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0112] Based on the same inventive concept, this application also provides a dishwasher control device for implementing the dishwasher control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more dishwasher control device embodiments provided below can be found in the limitations of the dishwasher control method described above, and will not be repeated here.

[0113] In one exemplary embodiment, such as Figure 7 As shown, a dishwasher control device is provided, including: a status determination module 702, a dirt judgment module 704, and a cleaning control module 706, wherein:

[0114] The status determination module 702 is used to respond to the cleaning command, acquire the detection data corresponding to each layer of the receiving component, and determine the dirt status of the tableware in each layer of the receiving component based on the detection data; the dishwasher includes multiple layers of receiving components, which are used to store tableware.

[0115] The dirt detection module 704 is used to determine the target container component in each layer of container components that holds dirty tableware based on the dirt status.

[0116] The cleaning control module 706 is used to control the cleaning device of the dishwasher to operate in a layered washing mode; in the layered washing mode, the cleaning device cleans the tableware in the target containment components; each containment component is located within the cleaning range of the cleaning device.

[0117] In some embodiments, the state determination module 702 is used to control the cleaning device to operate in a pre-wash mode; in the pre-wash mode, the spray component in the cleaning device sprays the tableware in each layer of the receiving component in sequence; after spraying the tableware in each layer of the receiving component, the turbidity parameter of the liquid to be discharged corresponding to each layer of the receiving component is obtained; and the dirt status of the tableware in each layer of the receiving component is determined based on each turbidity parameter.

[0118] In some embodiments, the state determination module 702 is used to determine that the dirty state of the tableware in the containing component is a stain state when the turbidity parameter is greater than or equal to a preset turbidity threshold.

[0119] The dirt detection module 704 is also used to determine the container component as the target container component for storing dirty tableware when the dirt state of the tableware in the container component is a stained state.

[0120] In some embodiments, the cleaning control module 706 is further configured to determine the dirt level of the tableware in the receiving component when the dirt state of the tableware in the receiving component is a stained state; and determine the initial washing parameters corresponding to the layered washing mode based on the dirt level.

[0121] In some embodiments, the cleaning control module 706 is further configured to output a corresponding prompt signal when it is determined, based on the state of soiling, that there are no soiled tableware in each layer of the receiving component.

[0122] In some embodiments, the cleaning control module 706 is further configured to control the cleaning device to operate in a full-layer washing mode in response to a confirmed cleaning command; in the full-layer washing mode, the cleaning device cleans the tableware in each containing component.

[0123] The various modules in the aforementioned dishwasher control device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device in hardware form, or stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module.

[0124] In one exemplary embodiment, a dishwasher is provided. (As...) Figure 1 As shown, the dishwasher includes a dishwasher 102 and a controller 104. The dishwasher 102 includes a multi-layer holding assembly and a cleaning device. The holding assembly is used to store tableware, and the number of layers and the capacity of each layer can be flexibly set according to actual usage needs and installation space. The layered design helps to make efficient use of space and improve the efficiency and stability of tableware placement. In some embodiments, the holding assembly is a bowl basket, specifically a two-layer structure: an upper bowl basket and a lower bowl basket. The upper bowl basket can be used to place smaller, lighter tableware, such as small bowls, cups, and condiment plates, while the lower bowl basket can hold larger, heavier tableware, such as large bowls and pots.

[0125] The cleaning device is electrically connected to the controller 104. Each layer of the receiving components is located within the cleaning range of the cleaning device, which is used to clean various types of tableware placed in the receiving components. In some embodiments, the cleaning device includes a spray assembly electrically connected to the controller 104. Under the control of the controller 104, the spray assembly can spray high-pressure water jets from multiple angles to powerfully rinse the tableware placed in the receiving components, effectively removing food residue and stains from the tableware.

[0126] In some embodiments, the cleaning device includes multiple sets of spraying components. Specifically, each spraying component is arranged in a one-to-one correspondence with a receiving component, that is, each set of spraying components independently sprays a layer of tableware in the receiving component to achieve layered cleaning of the tableware. The structure of the spraying components is not limited, for example, a spraying arm or other forms can be used.

[0127] It's understandable that the washing unit can include more components depending on the specific needs, such as a water pump assembly, a heating assembly, and a dispenser. The water pump assembly ensures a stable and continuous flow of water to the spray assembly, maintaining consistent rinsing pressure. The heating assembly heats the water entering the dishwasher; the high-temperature water not only dissolves grease on dishes more effectively but also sterilizes and disinfects. The dispenser dispenses detergent according to a preset program, further enhancing the washing effect.

[0128] In some embodiments, the dishwasher further includes a detection device electrically connected to the controller 104, the controller 104 acquiring detection data from the detection device to determine the soiling status of the tableware in each layer of the receiving assembly. In some embodiments, the detection device may be a sensor specifically designed for detecting the soiling status of the tableware, such as an image sensor, an odor sensor, an ultrasonic sensor, etc., and the controller determines the soiling status of the tableware in each layer of the receiving assembly based on the detection data from the image sensor, odor sensor, or ultrasonic sensor.

[0129] In some optional embodiments, the detection device reuses the existing turbidity detection device in the dishwasher. During dishwasher operation, the water flow carries dirt from the surface of the dishes as it rinses them, causing the water flow to exhibit different levels of turbidity. The turbidity detection device can detect the turbidity parameters corresponding to the dishes in each layer of the container and transmit them to the controller 104. The controller 104 determines the soiling status of the dishes in each layer of the container based on the corresponding turbidity parameters. Therefore, there is no need to set up additional sensors (such as image sensors) or other detection devices specifically for detecting the soiling status of the dishes; the existing turbidity detection device can be directly utilized, allowing the dishwasher to maintain complete functionality while effectively controlling the cost.

[0130] Furthermore, in some embodiments, the dishwasher also includes a washing chamber and a water cup. All the accommodating components and cleaning devices are disposed within the washing chamber, which provides a stable space for cleaning and storing the tableware. Depending on actual needs, the washing chamber can be configured as a closed or open chamber. The accommodating components within the washing chamber can be physically separated by partitions, or other methods of separation can be used; this embodiment does not limit this approach.

[0131] The water cup, located at the bottom of the washing chamber, plays a crucial role in collecting and temporarily storing wash water. A turbidity detection device can be placed inside the water cup. When wash water containing stains from various layers of tableware flows into the cup, the device accurately detects the turbidity parameters corresponding to the tableware in each layer of the container. This layout facilitates the natural collection of wash water, allows for accurate turbidity detection, and also streamlines subsequent drainage, making the dishwashing process smoother and more efficient.

[0132] In other embodiments, the dishwasher also includes a turbidity detection chamber, which is connected to the washing chamber. Specifically, the washing chamber is connected to the turbidity detection chamber via a water cup at the bottom. A turbidity detection device is located within the turbidity detection chamber. Therefore, by providing a turbidity detection chamber independent of the dishwasher's washing chamber, water from the washing chamber can be introduced into the turbidity detection chamber for detection. This mitigates the impact of interference factors such as water wave vibration, detergent residue obstruction, and air bubbles during dishwasher operation on turbidity detection, effectively improving the accuracy and stability of turbidity detection.

[0133] The controller 104 is used to control the dishwasher according to the dishwasher control method of the above embodiments.
