Technical Field

[0001] This application relates to the field of household appliance technology. More specifically, it relates to a cleaning device and its control method. Background Technology

[0002] Some cleaning equipment (such as dishwashers and washing machines) are equipped with an automatic detergent dispensing module, which allows the detergent to be added once and used multiple times. Users only need to add detergent once after it has been completely used up, without having to add it every time they use the machine.

[0003] Currently, cleaning equipment only prompts users to add detergent when it is nearly empty, but it cannot display the remaining detergent level in real time, resulting in a poor user experience. Summary of the Invention

[0052] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0054] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0055] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0056] The terms "first" and "second" are configured for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0057] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] As mentioned earlier, current cleaning equipment only activates when the detergent is nearly depleted. This is achieved by bringing a floating, magnetic float in the detergent dispenser closer to a fixed reed switch, which then sends a signal to the circuit board. The low detergent indicator light on the control panel illuminates to alert the user. However, this system cannot display the remaining detergent level in real time, resulting in a poor user experience.

[0059] The following uses a dishwasher as an example to illustrate the technical solution provided in the embodiments of this application.

[0060] Figure 1 This is a schematic diagram of the structure of a dishwasher provided in an embodiment of this application. Figure 1 As shown, the dishwasher can have a cabinet, which includes a dishwasher inner tub 10 and a door 11. The dishwasher inner tub 10 may have a washing chamber 12 and an opening. The door 11 may be provided at the opening of the dishwasher inner tub 10. Items such as pots, bowls, chopsticks, plates, dishes, and cups can be placed in the washing chamber 12 for washing.

[0061] Currently, the dishwasher washing process can be divided into four stages: pre-rinse, main wash, rinsing, and drying (also known as tumble drying). After the user selects a washing mode, the dishwasher starts and enters the pre-rinse stage. The dishwasher begins to inject washing water into the inner tank 10. After the water injection is complete, the dishwasher begins to rinse the items placed inside with the rinsing parameters corresponding to the washing mode (e.g., water pressure, duration, etc.), washing away some of the dirt. After rinsing is completed, the dishwasher drains the wastewater through the drain outlet and enters the main wash stage.

[0062] At the start of the main wash stage, the dishwasher begins to inject washing water into the inner tank 10. The water temperature to be heated is determined according to the main wash parameters corresponding to the washing mode. The injected washing water is heated by a heater located at the bottom of the inner tank 10. When the washing water is heated to the preset temperature, the heater is turned off, and the dishwasher begins to execute the washing program. The items to be cleaned are cleaned according to the main wash parameters corresponding to the washing mode. After the main wash stage is completed, the dishwasher drains the wastewater through the drain outlet and enters the hot rinsing stage.

[0063] At the start of the hot rinse stage, the dishwasher begins to inject washing water into the inner tank 10. The injected washing water is heated by a heater located at the bottom of the inner tank 10. When the washing water is heated to the preset temperature, the heater is turned off, and the dishwasher begins to execute the hot rinse program. The object to be cleaned is hot rinsed according to the rinsing parameters corresponding to the washing mode. After the hot rinse stage is completed, the dishwasher drains the wastewater through the drain outlet and enters the drying stage.

[0064] After entering the drying stage, the dishwasher can control the door 11 to open automatically and use the residual heat of the equipment after the hot rinsing stage to dry the object.

[0065] Figure 2 A schematic diagram of another dishwasher provided in this application embodiment is shown below. Figure 2 As shown: The dishwasher includes: inner tank 10, water tank 13, heater 14, water inlet valve 15, and controller 16.

[0066] The inner tank 10 has a washing chamber 12 for accommodating the object to be washed and the washing water, as well as an opening. A door 11 may be provided at the opening of the dishwasher inner tank 10.

[0067] Water tank 13 is used to store spare washing water.

[0068] The heater 14 is disposed adjacent to the inner tank 10 (e.g., at the bottom of the inner tank 10) and is used to start working in response to the operating command of the controller 16 to heat the washing water in the inner tank 10. Alternatively, the heater 14 can also stop working in response to the stop command of the controller 16, thus stopping the heating of the washing water in the inner tank 10.

[0069] The inlet valve 15 is connected to the inner tank 10, the water storage tank 13, and the external water inlet via an inlet pipe. It is used to open the valve in response to an opening command from the controller 16, allowing external water flow to inject washing water into the inner tank 10 and / or the water storage tank 13. Alternatively, the inlet valve 15 can also close the valve in response to a closing command from the controller 16, stopping the injection of washing water into the inner tank 10 and / or the water storage tank 13.

[0070] The controller 16 can be connected to the heater 14 and the water inlet valve 15, etc., to control the heater 14 and the water inlet valve 15 or to acquire data. Optionally, the controller 16 can be, for example, any chip with processing capabilities.

[0071] In some embodiments, the dishwasher also includes a door drive 17.

[0072] The door 11 can be located at the opening of the dishwasher inner tub 10 and is rotatably connected to the inner tub 10. When the door 11 is open, items can be placed or removed from the inner tub 10 through the opening. The door drive 17 is connected to the door and can be used to control the automatic opening and closing of the door 11.

[0073] In some embodiments, the door drive 17 may also be referred to as a door controller. The door drive 17 can respond to commands from the controller 16 to control the door 11 to open or close automatically. For example, if the controller 16 sends a command to the door drive 17 instructing the door 11 to open, the door drive 17 can respond to the command and control the door 11 to open automatically. If the controller 16 sends a command to the door drive 17 instructing the door 11 to close, the door drive 17 can respond to the command and control the door 11 to close automatically.

[0074] In some embodiments, after the hot rinsing stage, the dishwasher enters the drying stage. During the drying stage, the controller 16 sends a command to the door drive 17 to instruct the door 11 to open. The door drive 17 responds to this command by automatically opening the door 11, allowing the large amount of humid water vapor generated in the inner tub 10 during the hot rinsing stage to quickly dry all components within the inner tub 10. After a preset time (e.g., 1 minute), the controller 16 sends a command to the door drive 17 to instruct the door 11 to close. The door drive 17 responds to this command by automatically closing the door 11.

[0075] After the control door 11 is closed, the controller 16 utilizes the residual heat of the dishwasher—the internal components, the inner wall of the drum, and the surface of the object—to dry the cleaned item. Simultaneously, the vacuum insulation of the water tank extends the time the dishwasher remains at a high temperature, accelerating the drying process and reducing energy consumption, resulting in a rapid and energy-efficient drying effect.

[0076] In some embodiments, the dishwasher inner tub 10 is also provided with an upper spray arm 18, a shelf 19 and a lower spray arm 20.

[0077] The shelf 19 is used to store objects to be cleaned, such as pots, bowls, ladles, and basins. The upper spray arm 18 is used to draw washing water stored in the washing chamber and spray it onto the objects stored on the shelf 19 from above to clean them. The lower spray arm 20 is used to draw washing water stored in the washing chamber and spray it onto the objects stored on the shelf 19 from below to clean them.

[0078] It should be understood that when a dishwasher washes an object, it may use only the upper spray arm 18 to spray water on the object, or only the lower spray arm 20 to spray water on the object, or it may use both the upper spray arm 18 and the lower spray arm 20 simultaneously to spray water on the object. The above water spraying method can be determined based on the set washing program (e.g., washing program or hot rinsing program).

[0079] It should be understood that Figure 2 This description of the dishwasher's structure is merely an example of some components relevant to this application. This application does not limit whether the dishwasher includes other components.

[0080] Figure 3 A schematic diagram of another dishwasher provided in this application embodiment is shown below. Figure 3 As shown, the dishwasher also has a detergent dispensing assembly 21 on its body, which is configured to hold detergent.

[0081] In some embodiments, the detergent dispensing assembly 21 is further provided with a switch device (not shown), and the controller 16 is connected to the switch device. During the pre-rinse and main wash stages, the controller 16 can control the switch device to open or close to dispense detergent into the washing chamber.

[0082] In some embodiments, such as Figure 4 As shown, multiple electrodes 22 are disposed on the side wall of the detergent dispensing assembly 21, distributed from the bottom to the top of the side wall. The electrodes 22 are used to detect the presence of detergent at their respective locations.

[0083] Since electrodes can detect the capacitance of objects within a certain spatial distance, and the dielectric constant of different objects varies, the detected capacitance values ​​will differ. Because the dielectric constant of liquids is much greater than that of air (air's dielectric constant is typically <5, while liquid's is between 50 and 100), this order-of-magnitude difference in dielectric constant between air and liquids will also lead to order-of-magnitude differences in the detected capacitance values. Therefore, the presence of liquid can be determined based on the difference in capacitance values. For example, if a large capacitance value is detected by the top electrode, the detergent dispensing component 21 can be considered to be full of detergent.

[0084] In some embodiments, the plurality of electrodes 22 may be disposed on the inner sidewall of the detergent dispensing assembly 21.

[0085] In some embodiments, the plurality of electrodes 22 may be disposed on the outer wall of the detergent dispensing assembly 21.

[0086] In some embodiments, a sealed receiving cavity is formed between the outer and inner sidewalls of the detergent dispensing assembly 21, and the plurality of electrodes 22 may be disposed within the receiving cavity.

[0087] When the plurality of electrodes 22 are placed on the outer wall of the detergent dispensing assembly 21, or when the plurality of electrodes 22 are disposed within the receiving cavity, the electrodes 22 can be isolated from the detergent, thereby preventing the electrodes 22 from being immersed in the detergent and preventing the detergent from corroding the electrodes 22, thus improving the service life and detection accuracy of the electrodes 22.

[0088] In some embodiments, when the plurality of electrodes 22 are disposed on the outer side wall of the detergent dispensing assembly 21, in order to avoid the influence of the side wall of the detergent dispensing assembly 21 on the accuracy of the detection results, the side wall needs to have a uniform thickness and a thickness less than or equal to 5 millimeters (mm). For example, the thickness of the side wall of the detergent dispensing assembly 21 can be 5 millimeters, 4 millimeters, 3 millimeters, etc.

[0089] In some embodiments, please refer to Figure 3 The dishwasher also includes a display component 23, which is disposed on the dishwasher body and is used to display the remaining amount of detergent in the detergent dispensing component 21, so that the user can quickly understand the remaining amount of detergent. For example, the display component 23 can display the remaining amount of detergent as a percentage (such as 80%) or a progress bar.

[0090] The following is combined Figure 5 The process of determining the remaining amount of detergent in the embodiments of this application will be further explained.

[0091] Figure 5This is a flowchart illustrating a control method for a cleaning device provided in an embodiment of this application, as shown below. Figure 5 As shown, it includes:

[0092] S501. Obtain the capacitance values ​​collected by the multiple electrodes respectively.

[0093] In some embodiments, after power-on, the controller can receive capacitance values ​​collected by each electrode, or control the electrodes to collect capacitance values ​​to obtain capacitance values ​​collected by multiple electrodes respectively.

[0094] S502. Determine the remaining amount of detergent based on the plurality of said capacitance values, and display the remaining amount of detergent through the display component.

[0095] In some embodiments, when the capacitance values ​​collected by each electrode are obtained, the controller can determine whether the capacitance value corresponds to air or liquid based on the capacitance value. For example, if the collected capacitance value is greater than a preset value, it can be determined that the capacitance value corresponds to liquid; if the collected capacitance value is less than the preset value, it can be determined that the capacitance value corresponds to air.

[0096] In some embodiments, when the controller determines that each capacitor value is the capacitance value corresponding to air or the capacitance value corresponding to liquid, it can convert the capacitance value corresponding to air and the capacitance value corresponding to liquid into the corresponding constant value respectively.

[0097] For example, the capacitance value corresponding to air can be converted to 0, and the capacitance value corresponding to liquid can be converted to 1. Alternatively, the capacitance value corresponding to air can be converted to 1, and the capacitance value corresponding to liquid can be converted to 0. This application does not limit the conversion method.

[0098] In some embodiments, the controller stores the positions of each electrode plate on the sidewall. When determining the constant value corresponding to the capacitance value collected by each electrode, the constant values ​​can be combined based on the positions of each electrode to determine a target value. The target value can be used to characterize the capacitance value of the detergent dispensing component.

[0099] In some embodiments, the controller can arrange the constant values ​​sequentially from bottom to top to obtain the target value. Alternatively, the controller can arrange the constant values ​​sequentially from top to bottom to obtain the target value. This application does not limit the sorting method.

[0100] For example, assuming the liquid is arranged in order from bottom to top and its capacitance value is converted to 1, the outer wall of the detergent dispensing component has five electrodes: electrode 1, electrode 2, electrode 3, electrode 4, and electrode 5, arranged sequentially from the bottom to the top of the side wall. Electrodes 1-4 all have a constant value of 1, while electrode 5 has a constant value of 0. Therefore, combining these constant values ​​according to their positional order yields a target value of 11110.

[0101] In some embodiments, after determining the target value, the controller can determine the remaining amount of detergent corresponding to the target value based on the target value and a preset mapping relationship.

[0102] For example, the controller can query the remaining amount of detergent corresponding to the target value of 11110 in a preset mapping table. For instance, if the query shows that the remaining amount of detergent corresponding to the target value of 11110 is 75%, the controller can display the remaining amount of detergent as a percentage, a progress bar, or different colors through a display component.

[0103] It should be understood that a constant value of 0 indicates air at that location, a constant value of 1 indicates liquid at that location, and a target value of 11110 indicates that liquid is present at locations corresponding to electrodes 1-4, while location 5 is air and not liquid. Since electrodes 1-5 are evenly arranged from bottom to top, electrode 1 corresponds to the 0% position, electrode 2 to the 25% position, electrode 3 to the 50% position, electrode 4 to the 75% position, and electrode 5 to the 100% position. When liquid is present at electrode 4 and air is present at electrode 5, it indicates that the detergent dispensing unit has at least 75% detergent remaining between electrodes 4 and 5. Therefore, the current remaining amount of 75% can be displayed on the display.

[0104] The control method for the cleaning equipment provided in this application uses multiple electrodes to detect the capacitance value at different locations of the detergent dispensing component. Based on the magnitude difference in capacitance between water and liquids, it can achieve real-time detection and display of the remaining detergent in the detergent dispensing component. This informs the user of the current remaining detergent level, effectively improving the user experience.

[0105] Based on the above embodiments, as the cleaning equipment is used, the material of the detergent dispensing component will age, and the electrode plates will also age, which will lead to errors in the measurement of capacitance value. For example, when there is no liquid level, it may be mistakenly judged as having detergent. To avoid this problem, the controller can also perform zero-point calibration of detergent.

[0106] Figure 6A flowchart illustrating the control method for the cleaning equipment provided in this application embodiment. Figure 2 ,like Figure 6 As shown, it includes:

[0107] S601. When the cumulative amount of detergent dispensed is equal to the capacity of the detergent dispensing component, and the target value continues to decrease during the time when the cumulative amount of detergent dispensed is equal to the capacity of the detergent dispensing component, obtain the current corresponding target value.

[0108] In some embodiments, the cumulative amount of detergent dispensed may refer to the total amount of detergent dispensed from the first operation of the cleaning equipment to the present. For example, during the cleaning process, if the controller controls the switch of the detergent dispensing component to open once, 10 ml of detergent can be dispensed. If the switch has been opened a total of 40 times since the first operation of the cleaning equipment, then the cumulative amount of detergent dispensed is 400 ml (10*40).

[0109] The capacity of a detergent dispensing unit can refer to the maximum volume of detergent that the detergent dispensing unit can hold at one time (i.e., how much detergent can be held when the detergent dispensing unit is full).

[0110] For example, if the capacity of the detergent dispensing component is 400 ml and the controller records 40 times of detergent dispensing (10 ml each time), it can be determined that the cumulative amount of detergent dispensed is equal to the capacity of the detergent dispensing component.

[0111] During the period when the cumulative amount of detergent dispensed equals the capacity of the detergent dispensing component, the controller can determine whether the target value is continuously decreasing. For example, if the target value is 11111 for the first detection, 11110 for the second, 11100 for the third, 11000 for the fourth, and 10000 for the fifth, then it is determined that the target value is continuously decreasing during this period. This means that the user has not refilled the detergent during this period, and that the detergent dispensing component is empty when the cumulative amount of detergent dispensed equals the capacity of the detergent dispensing component.

[0112] At this point, the controller determines the current target value based on the capacitance values ​​returned by each electrode, meaning that the current target value corresponds to an empty detergent level.

[0113] S602. Update the mapping relationship using the current corresponding target value.

[0114] In some embodiments, when determining the current target value, the mapping relationship can be updated based on the current corresponding target value. For example, if the current target value is 10000, a mapping relationship of 10000 corresponding to a remainder of 0 can be added to the mapping table, or the original mapping relationship of 00000 corresponding to a remainder of 0 can be modified to 10000, or the original mapping relationship of 10000 corresponding to a remainder of less than 25% can be modified to a mapping relationship of 10000 corresponding to a remainder of 0.

[0115] In some embodiments, if the mapping relationship between the current target value and the remainder of 0 is consistent with that in the mapping table, the current update action can be canceled.

[0116] The control method for the cleaning equipment provided in this application can avoid misjudging the presence of detergent when the liquid level is empty by updating the mapping relationship when the remaining amount is 0, thereby reducing the probability of incomplete cleaning.

[0117] Based on the above embodiments, this application also provides a control device for a cleaning equipment.

[0118] Figure 7 A schematic diagram of the control device for the cleaning equipment provided in this application is shown below. Figure 7 As shown, it includes:

[0119] The acquisition module 701 is used to acquire the capacitance values ​​collected by the multiple electrodes respectively.

[0120] Processing module 702 is used to determine the remaining amount of detergent based on the plurality of said capacitance values.

[0121] Display module 703 is used to display the remaining amount of detergent through the display component.

[0122] In some embodiments, the processing module 702 is further configured to convert the capacitance value into a constant value based on the relationship between the capacitance value and a preset value; combine the constant values ​​according to the position of the electrode to determine a target value; and determine the remaining amount of detergent according to the target value.

[0123] In some embodiments, the processing module 702 is further configured to arrange the constant values ​​sequentially from bottom to top to obtain the target value.

[0124] In some embodiments, the processing module 702 is further configured to determine the remaining amount of detergent based on the target value and the mapping relationship between the target value and the remaining amount.

[0125] In some embodiments, the processing module 702 is further configured to: obtain a current corresponding target value when the cumulative amount of detergent dispensed is equal to the capacity of the detergent dispensing component, and the target value continues to decrease during the time when the cumulative amount of detergent dispensed is equal to the capacity of the detergent dispensing component; the current corresponding target value indicates that the remaining amount of detergent is empty; and update the mapping relationship using the current corresponding target value.

[0126] In some embodiments, the display module 703 is also configured to display the remaining amount of detergent as a percentage or as a progress bar via the display component.
