[0053] To make the features and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the embodiments of this application.

[0054] In recent years, with the rapid development of the home appliance industry, washing equipment has become increasingly popular. To provide users with a better experience, humidity sensors have been gradually introduced into washing equipment to optimize the drying process. However, the introduction of humidity sensors into washing equipment can cause reliability issues. For example, steam discharged or leaking from the washing equipment can cause high-temperature, high-humidity steam to condense on the surface of the humidity sensor, leading to sensor failure; similarly, inorganic salts condensing on the surface of the humidity sensor can also cause it to malfunction.

[0055] When the humidity sensor fails, the exhaust gas during the drying process of the washing equipment cannot be monitored in real time, which will cause the exhaust gas to condense on the corresponding external solid wall surface of the washing equipment, thus affecting the user experience.

[0056] To address the aforementioned technical problems, this application provides a drying control method for a washing device. The washing device includes a washing chamber and an exhaust device. The method includes: before executing a drying command, detecting the sensor status of a humidity sensor and determining that the sensor status is a sensor failure state; wherein, the humidity sensor is disposed within the exhaust device and is used to detect the humidity of the equipment exhaust gas discharged from the exhaust device, the equipment exhaust gas including at least one of the washing chamber exhaust gas discharged from the washing chamber and the externally drawn-in gas; obtaining the highest washing temperature and a set temperature threshold in the washing mode corresponding to the drying command; executing the drying command, determining the washing mode type of the washing device based on the highest washing temperature and the set temperature threshold, and performing equipment drying control on the washing device corresponding to the washing mode type.

[0057] In this method, before the washing equipment executes the drying command, the sensor status of the humidity sensor in the washing equipment is detected. When the sensor status is determined to be sensor failure, the highest washing temperature in the washing mode and the set temperature threshold are obtained, and the drying command is executed. By setting the temperature threshold and the highest washing temperature in the washing mode, the washing mode type of the washing equipment is determined. Thus, targeted equipment drying control is performed on the washing equipment after sensor failure for the washing mode type. This solves the technical problem that various deposits may form on the surface of the humidity sensor during operation, causing the humidity sensor to fail and preventing the washing equipment from working properly during the drying process.

[0058] Please see Figure 1 , Figure 1 This is a flowchart illustrating a drying control method for a washing machine provided in an embodiment of this application. The executing entity in this embodiment can be the washing machine itself, a processor within the washing machine, or a drying control service within the washing machine. For ease of description, the following example uses a processor within the washing machine as the executing entity to illustrate the specific execution process of the drying control method for the washing machine; wherein the washing machine includes a washing chamber and an exhaust device, and specifically includes the following steps:

[0059] S102: Before executing the drying command, the sensor status of the humidity sensor is detected, and the sensor status is determined to be a sensor failure state; wherein, the humidity sensor is installed in the exhaust device and is used to detect the humidity of the equipment exhaust gas discharged from the exhaust device, and the equipment exhaust gas includes at least one of the washing chamber exhaust gas discharged from the washing chamber and the external intake gas drawn in from the outside.

[0060] Before executing the drying command, the washing equipment checks the status of the humidity sensor, including whether it is in a faulty or normal state. Typically, the humidity sensor status is checked after the washing cycle ends and before the drying command is executed. Here, the washing cycle refers to the washing program executed before the drying command. When the washing equipment enters the washing cycle, it washes the items in the washing chamber.

[0061] Generally, after the washing cycle ends, the washing machine prepares to dry the items in the washing chamber. At this time, the status of the humidity sensor in the washing machine can be checked. Here, the humidity sensor in the washing machine can be located inside the exhaust device.

[0062] Specifically, the humidity sensor can be installed in the exhaust duct of the exhaust port corresponding to the exhaust gas of the washing equipment. When the equipment exhaust gas includes exhaust gas from the washing chamber and externally drawn gas, the exhaust duct is used to mix the exhaust gas from the washing chamber and the externally drawn gas and discharge them from the washing equipment; when the equipment exhaust gas includes exhaust gas from the washing chamber, the exhaust duct is used to discharge the exhaust gas from the washing chamber; when the equipment exhaust gas includes externally drawn gas, the exhaust duct is used to discharge the externally drawn gas from the washing equipment. The equipment exhaust gas includes at least one of the exhaust gas from the washing chamber and externally drawn gas. Specifically, the equipment exhaust gas may include exhaust gas from the washing chamber and externally drawn gas; or, the equipment exhaust gas may include exhaust gas from the washing chamber; or, the equipment exhaust gas may include externally drawn gas.

[0063] During the detection of the humidity sensor's status, the air discharged from the washing chamber of the washing equipment can be briefly vented (e.g., for 80 seconds). During this time, the humidity of the air discharged from the washing chamber will decrease slightly. After maintaining this state for a period of time, the humidity sensor's humidity sensing signal will be acquired. When the humidity sensor's humidity sensing signal is detected as 0 or the value of the humidity sensing signal is less than or equal to the risk signal threshold, the humidity sensor's status can be considered as a sensor failure state. When the humidity sensor's status is detected as a sensor failure state at least twice, a failure prompt can be issued, such as an alarm light.

[0064] When the humidity sensor detects a humidity sensing signal greater than 0 or a value greater than the risk signal threshold, the sensor is considered to be in normal condition. Here, the risk signal threshold is greater than 0. When the humidity sensing signal is less than the risk signal threshold, it indicates that the humidity sensing signal is weak and outside the normal signal range.

[0065] After the humidity sensor is identified as faulty, you can try to restore its normal operation. Specifically, you can use a fan to draw in outside air and dry the humidity sensor in the exhaust system, preventing high-temperature, high-humidity steam from condensing on the sensor surface and causing it to malfunction. After the set drying time, stop the drying process and briefly vent the air from the washing chamber of the washing machine. Simultaneously, re-acquire the humidity sensor's signal. If the humidity sensor signal is again 0 or less than or equal to the risk signal threshold, the sensor is considered faulty. If the humidity sensor signal is again greater than 0 or greater than the risk signal threshold, the sensor is considered functioning normally.

[0066] When the humidity sensor is in a normal state, the items in the washing chamber of the washing machine are dried based on the preset normal drying logic. When the humidity sensor is in a faulty state, the humidity sensor can be disconnected from the circuit. This can be achieved by adding an additional switching MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) transistor to the upstream circuit of the humidity sensor. Upon detecting a fault, the humidity sensor will be disconnected from the circuit. After the humidity sensor is in a faulty state, subsequent steps continue to be executed.

[0067] S104: Obtain the highest washing temperature and the set temperature threshold in the washing mode corresponding to the drying instruction. The highest washing temperature in the washing mode can be obtained based on the temperature sensor in the washing chamber of the washing equipment. The set temperature threshold is used to distinguish the washing mode type, such as a high-temperature washing mode and a low-temperature washing mode. For example, the set temperature threshold can be 55°C. When the highest washing temperature in the washing mode is greater than 55°C, the washing mode type can be considered a high-temperature washing mode; when the highest washing temperature in the washing mode is less than or equal to 55°C, the washing mode type can be considered a low-temperature washing mode.

[0068] Of course, the temperature threshold can also be set specifically based on the washing mode type of the washing equipment, thereby distinguishing the washing mode type based on the set temperature threshold.

[0069] To more accurately determine the set temperature threshold for distinguishing washing modes based on actual application environments, the set temperature threshold can be configured based on the specific equipment parameters of the washing machine and environmental parameters. Here, environmental parameters can include ambient humidity and ambient temperature, which can be obtained during the washing initialization phase. During the initialization phase, the fan in the exhaust duct is turned on for 2 minutes, during which the temperature and humidity of the gas in the exhaust duct are measured. The lowest temperature and the corresponding humidity are used as the ambient humidity and ambient temperature. Of course, these can also be obtained from external devices, but this will not be elaborated upon here.

[0070] For example, the set temperature threshold can be obtained by looking up a table based on the equipment parameters and environmental parameters of the washing equipment; or, the set temperature threshold can be determined based on a pre-trained target machine learning model, such as by inputting the equipment parameters and environmental parameters into the target machine learning model and obtaining the set temperature threshold based on the target machine learning model; wherein, the target machine learning model can be trained on an initial machine learning model based on the label equipment parameters, label environmental parameters and label set temperature threshold.

[0071] S106: Execute the drying command, determine the washing mode type of the washing equipment based on the highest washing temperature and the set temperature threshold, and perform equipment drying control corresponding to the washing mode type.

[0072] Specifically, by comparing the highest washing temperature with a set temperature threshold, the washing mode type corresponding to the highest washing temperature is determined. Different washing mode types can be distinguished by the highest washing temperature within their respective washing modes. After determining the washing mode type of the washing equipment, targeted drying control is implemented based on drying instructions corresponding to the washing mode type.

[0073] The set temperature threshold can be one, two, or more. When there is only one set temperature threshold, the highest washing temperature and the set temperature threshold can be directly compared. When the highest washing temperature is greater than the set temperature threshold, it indicates that the exhaust gas discharged during the drying process of the washing equipment is more likely to condense on the wall surface of the corresponding external solid. When the highest washing temperature is less than or equal to the set temperature threshold, the exhaust gas discharged during the drying process of the washing equipment is less likely to condense on the wall surface of the corresponding external solid.

[0074] When there are two or more set temperature thresholds, a corresponding set temperature threshold range is generated based on the set temperature thresholds, thereby determining the set temperature threshold range in which the highest washing temperature is located, and then determining the washing mode type of the washing equipment based on the set temperature threshold range in which the highest washing temperature is located.

[0075] This application provides a drying control method for a washing machine, the washing machine including a washing chamber and an exhaust device. The method includes: before executing a drying command, detecting the sensor status of a humidity sensor and determining that the sensor status is a sensor failure state; wherein, the humidity sensor is disposed in the exhaust device and is used to detect the humidity of the equipment exhaust gas discharged from the exhaust device, the equipment exhaust gas including at least one of the washing chamber exhaust gas discharged from the washing chamber and the externally drawn-in gas; obtaining the highest washing temperature and a set temperature threshold in the washing mode corresponding to the drying command; executing the drying command, determining the washing mode type of the washing machine based on the highest washing temperature and the set temperature threshold, and performing equipment drying control on the washing machine corresponding to the washing mode type.

[0076] In this method, before the washing equipment executes the drying command, the sensor status of the humidity sensor in the washing equipment is detected. When the sensor status is determined to be sensor failure, the highest washing temperature and the set temperature threshold in the washing mode are obtained. By setting the temperature threshold and the highest washing temperature in the washing mode, the washing mode type of the washing equipment is determined. Then, targeted equipment drying control is performed on the washing equipment after sensor failure for the washing mode type. This solves the technical problem that various deposits may form on the surface of the humidity sensor during operation, causing the humidity sensor to fail and making the drying process of the washing equipment unable to work normally.

[0077] In the embodiments provided in this application, step S106 involves determining the washing mode type of the washing equipment based on the highest washing temperature and a set temperature threshold, and performing equipment drying control corresponding to the washing mode type, including:

[0078] If the maximum washing temperature is greater than the set temperature threshold, the first drying control logic is executed to control the drying of the equipment.

[0079] If the maximum washing temperature is less than or equal to the set temperature threshold, the second drying control logic is executed to control the drying of the equipment.

[0080] Specifically, when the maximum washing temperature exceeds the set temperature threshold, it indicates that the exhaust gas from the washing equipment during the drying process is highly likely to condense on the wall surface of the corresponding external solid. In this case, the washing equipment is controlled for drying based on the first drying control logic to prevent the exhaust gas from condensing on the wall surface. Here, the first drying control logic is used to reduce the dew point temperature of the exhaust gas so that it is lower than the initial ambient temperature.

[0081] When the maximum washing temperature is less than or equal to the set temperature threshold, it indicates that the exhaust gas from the washing equipment during the drying process is less likely to condense on the wall surface of the corresponding external solid. In this case, the corresponding second drying control logic can be used for equipment drying control.

[0082] Meanwhile, it should be noted that when controlling the drying of the equipment based on the first drying control logic or the second drying control logic, while ensuring that the dew point temperature of the discharged gas is lower than the initial ambient temperature, the discharge volume of the gas discharged from the washing chamber per unit time should be increased as much as possible to improve the drying efficiency.

[0083] In this embodiment, a first drying control logic is used to control the drying of the washing equipment when the maximum washing temperature is greater than a set temperature threshold; and a second drying control logic is used to control the drying of the washing equipment when the maximum washing temperature is less than or equal to the set temperature threshold. This is to specifically reduce the dew point temperature of the exhaust gas from the washing equipment so that the dew point temperature of the exhaust gas is lower than the initial ambient temperature, thereby avoiding the generation of condensate.

[0084] Please see Figure 2 , Figure 2 This is a schematic diagram of the exhaust device of a washing apparatus provided in an embodiment of this application. Figure 2 As shown, in the embodiments provided in this application, the exhaust device includes a first air inlet 202, a second air inlet 203, an exhaust outlet 204, and a valve plate 201. The first air inlet 202 is connected to the washing chamber, and the second air inlet 203 and the exhaust outlet 204 are respectively connected to the outside air. The valve plate 201 is used to control the opening degree of the first air inlet and / or the second air inlet of the exhaust device. In the above embodiments, the first drying control logic is executed to control the drying of the equipment, including:

[0085] The periodic gas mixing regulation logic for the gas discharged from the washing chamber and the gas drawn in from the outside is initiated. Based on the periodic gas mixing regulation logic, the valve plate is periodically adjusted to periodically increase the opening of the first air inlet for the gas discharged from the washing chamber and periodically decrease the opening of the second air inlet for the gas drawn in from the outside until the opening of the first air inlet is greater than or equal to the preset opening threshold.

[0086] The first air inlet and the second air inlet are connected by an air duct. The first air inlet is used to discharge the gas discharged from the washing chamber. The second air inlet is used to draw in the gas drawn in from the outside of the washing chamber. The exhaust port is used to discharge the gas discharged from the washing chamber and / or the gas drawn in from the outside to the outside of the washing equipment.

[0087] During the process of controlling the equipment drying by executing the first drying control logic, the valve plate is adjusted by the periodic gas mixing regulation logic, thereby periodically increasing the opening of the first air inlet and periodically decreasing the opening of the second air inlet.

[0088] By periodically increasing the opening of the first air inlet, the proportion of gas discharged from the washing chamber in the exhaust gas of the equipment is periodically increased. At the same time, by periodically decreasing the opening of the second air inlet, the proportion of gas drawn in from the outside is periodically decreased. When the periodic gas mixing and adjustment logic is first executed, the washing mode has usually just ended. The temperature and humidity in the washing chamber of the washing equipment are relatively high, that is, the dew point temperature of the gas in the washing chamber is usually higher than the initial ambient temperature.

[0089] Therefore, to quickly reduce the dew point temperature of the exhaust gas from the equipment to below the ambient temperature, the valve plates can be adjusted initially to set the proportion of exhaust gas from the washing chamber to the minimum settable value, while simultaneously setting the proportion of externally drawn-in gas to the maximum settable value. Since the dew point temperature of the externally drawn-in gas is lower than the ambient temperature, this maximizes the proportion of externally drawn-in gas in the equipment's exhaust gas, thereby reducing the dew point temperature of the exhaust gas to below the initial ambient temperature.

[0090] As the washing chamber of the washing equipment continuously discharges gas, its dew point temperature gradually decreases. At this point, the proportion of the discharged gas from the washing chamber can be gradually increased while the proportion of externally drawn-in gas in the discharged gas can be decreased. Therefore, over time, the opening of the first air inlet can be periodically increased while the opening of the second air inlet can be periodically decreased, thereby periodically increasing the proportion of the discharged gas from the washing chamber until the opening of the first air inlet is greater than or equal to a preset threshold, thus improving the drying control efficiency of the washing equipment.

[0091] It should be noted that when the first air inlet reaches the preset opening threshold, the opening of the first air inlet can be in a fully open state, or it can be in another opening state that is set to be close to fully open. When the opening of the first air inlet is greater than or equal to the preset opening threshold, the second air inlet can be in a closed state or a partially open state.

[0092] In the embodiments provided in this application, as the gas discharged from the washing chamber is continuously discharged, the dew point temperature of the gas discharged from the washing chamber gradually decreases. This allows the opening of the first air inlet to be periodically increased while the opening of the second air inlet is periodically decreased, thereby periodically increasing the proportion of the gas discharged from the washing chamber in the gas discharged from the equipment until the opening of the first air inlet is greater than or equal to a preset opening threshold. This improves the drying control efficiency of the washing equipment while avoiding the generation of condensate.

[0093] Please see Figure 3 , Figure 3 This is a schematic diagram illustrating a process for adjusting the opening of the first air inlet and the second air inlet based on a periodic gas mixing regulation logic, as provided in an embodiment of this application.

[0094] like Figure 3 As shown, in the above embodiment, the valve plate is periodically adjusted based on the periodic gas mixing regulation logic to periodically increase the opening of the first air inlet for discharging gas from the washing chamber, and periodically decrease the opening of the second air inlet for drawing in external air, including:

[0095] S302: Determine the preset cycle and the corresponding gas mixing adjustment parameters.

[0096] The preset cycle includes multiple sub-cycles, such as two, three, or four. The number of sub-cycles in the preset cycle can be determined based on gas mixing adjustment parameters. These parameters are used to adjust the proportion of exhaust gas from the washing chamber and the proportion of intake gas from the outside.

[0097] For example, please refer to Figure 2 As shown, the control is achieved through gas mixing adjustment parameters. Figure 2 The rotation angle of the valve plate 201 adjusts the ratio of gas discharged from the washing chamber to the ratio of gas drawn in from the outside. When the washing equipment is in washing mode, the valve plate 201 covers the first air inlet corresponding to the gas discharged from the washing chamber, i.e., closes the first air inlet, thus isolating the washing chamber of the washing equipment from the outside. When the washing equipment is drying, the angle θ in the figure is greater than or equal to 0° and less than or equal to 90°. In addition, when detecting the sensor status of the humidity sensor, the angle θ can be 70°.

[0098] The gas mixing adjustment parameter can be the clockwise rotation angle of valve plate 201. When the gas mixing adjustment parameter is 5°, the number of sub-cycles in the preset cycle can be 90° plus 5°, i.e., 18. Of course, the gas mixing adjustment parameter α can be set based on specific requirements.

[0099] It should be understood that in other embodiments, the gas mixing adjustment parameter may also be other parameters used to adjust the ratio of gas discharged from the washing chamber to the ratio of gas drawn in from the outside, such as the fan speed corresponding to the gas discharged from the washing chamber and the fan speed corresponding to the gas drawn in from the outside.

[0100] S304: Within a preset period, based on the gas mixing adjustment parameters, the valve plate is periodically controlled to increase the opening of the first air inlet to increase the proportion of gas discharged from the washing chamber, and the opening of the second air inlet is periodically decreased to reduce the proportion of gas drawn in from the outside. The proportion of gas discharged from the washing chamber is negatively correlated with the proportion of gas drawn in from the outside.

[0101] Within a preset period, the valve plate can be periodically controlled to increase the opening of the first air inlet and periodically decrease the opening of the second air inlet based on gas mixing adjustment parameters. This periodically increases the proportion of gas discharged from the washing chamber in the exhaust gas and periodically decreases the proportion of externally drawn-in gas. The gas mixing adjustment parameters can be the valve plate rotation angle of the valve plate, which is rotatably positioned between the first and second air inlets.

[0102] like Figure 2 As shown, while increasing the opening of the first air inlet via the valve plate, the opening of the second air inlet is simultaneously decreased. Increasing the opening of the first air inlet increases the proportion of gas discharged from the washing chamber, while decreasing the opening of the second air inlet decreases the proportion of gas discharged from the washing chamber. Similarly, decreasing the opening of the first air inlet decreases the proportion of gas discharged from the washing chamber, while increasing the opening of the second air inlet increases the proportion of gas discharged from the washing chamber. In this embodiment, the proportion of gas discharged from the washing chamber is negatively correlated with the proportion of gas drawn in from the outside.

[0103] In the embodiments provided in this application, as the gas discharged from the washing chamber is continuously discharged, the dew point temperature of the gas discharged from the washing chamber gradually decreases. By periodically controlling the valve plate to increase the opening of the first air inlet and periodically decrease the opening of the second air inlet through the gas mixing adjustment parameters, the proportion of the gas discharged from the washing chamber in the equipment's exhaust gas is periodically increased and the proportion of the gas drawn in from the outside is periodically decreased, so as to avoid the generation of condensate and improve the drying control efficiency of the washing equipment.

[0104] Please see Figure 4 , Figure 4 This is a schematic flowchart illustrating a periodic control valve based on gas mixing regulation parameters, provided as an embodiment of this application. The preset period includes at least two sub-periods, and the gas mixing regulation parameters include sub-period gas mixing regulation parameters corresponding to the sub-periods.

[0105] S304 periodically controls the valve plate to increase the opening of the first air inlet based on gas mixing adjustment parameters to increase the proportion of gas discharged from the washing chamber, and periodically decreases the opening of the second air inlet to reduce the proportion of gas drawn in from the outside, including:

[0106] S402: Sequentially execute the sub-cycle gas mixing adjustment logic corresponding to each sub-cycle in the preset cycle, gradually increasing the proportion of gas discharged from the washing chamber and gradually decreasing the proportion of gas drawn in from the outside.

[0107] When the preset cycle includes multiple sub-cycles, the sub-cycle gas mixing adjustment parameters corresponding to each sub-cycle can be the same or different, and can be flexibly set according to the actual application scenario. By using the sub-cycle gas mixing adjustment parameters corresponding to different sub-cycles, the sub-cycle gas mixing adjustment logic corresponding to each sub-cycle is executed, thereby gradually increasing the proportion of gas discharged from the washing chamber and gradually decreasing the proportion of gas drawn in from the outside.

[0108] For example, when the preset cycle includes multiple sub-cycles, in the first sub-cycle, when the sub-cycle gas mixing adjustment parameter for the first sub-cycle is 5°, θ can be determined to be 85°. At this time, the opening of the first air inlet can be 5°, and the opening of the second air inlet can be 85°.

[0109] Because the washing cycle has just ended, the temperature and humidity inside the washing chamber of the washing equipment are relatively high; that is, the dew point temperature of the gas discharged from the washing chamber is usually greater than or equal to the ambient temperature. Therefore, in order to quickly reduce the dew point temperature of the gas discharged from the washing chamber to below the ambient temperature, the proportion of the gas discharged from the washing chamber in the equipment's exhaust gas can be adjusted to the minimum settable value, while the proportion of the externally drawn-in gas can be adjusted to the maximum settable value. This state should be maintained for a preset sub-cycle duration, such as 70 seconds. The duration can be recorded every 10 seconds; or initially maintained for 20 seconds, then recorded 5 times every 10 seconds, and finally the duration of maintenance is determined by counting the number of times. It should be understood that throughout the entire preset cycle, the fan in the exhaust duct corresponding to the exhaust port continuously mixes the gas discharged from the washing chamber and the externally drawn-in gas and discharges it from the washing equipment.

[0110] Similarly, when entering the second sub-cycle, when the sub-cycle gas mixing adjustment parameter for the second sub-cycle is 5°, the valve plate is rotated clockwise to adjust θ to 80°. At this time, the opening of the first air inlet can be 10°, and the opening of the second air inlet can be 80°.

[0111] After the first sub-cycle, the temperature and humidity inside the washing chamber of the washing equipment decrease slightly. Therefore, based on the sub-cycle gas mixing adjustment parameters of the second sub-cycle, the proportion of gas discharged from the washing chamber and the proportion of gas drawn in from the outside can be increased slightly to keep the dew point temperature of the gas discharged from the washing equipment lower than the ambient temperature while maximizing the discharge of gas from the washing chamber. Similarly, the preset sub-cycle duration of the second sub-cycle can be maintained, which will not be elaborated here.

[0112] Similarly, in subsequent sub-cycles, θ can be further adjusted based on the sub-cycle gas mixing adjustment parameters corresponding to each sub-cycle. At the same time, the proportion of gas discharged from the washing chamber and the proportion of gas drawn in from the outside can be increased slightly based on the sub-cycle gas mixing adjustment parameters until θ is less than or equal to the preset angle value (e.g., 1°) or θ is 0°.

[0113] S404: Detect whether the opening degree of the first air inlet reaches the preset opening degree threshold.

[0114] Specifically, when the opening degree of the first air inlet reaches a preset opening degree threshold, the first air inlet can be in a fully open state. For example, as shown... Figure 2 As shown, when the opening degree of the first air inlet reaches the preset opening degree threshold, θ can be 0°, and the preset opening degree threshold can be 90°. Of course, in actual scenarios, the preset opening degree threshold can be located in the range around 90°.

[0115] S406: If the opening degree of the first air inlet is greater than or equal to the preset opening degree threshold, the sub-cycle gas mixing regulation logic is terminated and the equipment drying process is performed.

[0116] Specifically, when the opening degree of the first air inlet is greater than or equal to the preset opening degree threshold, it indicates that the first air inlet is in a fully open state, at which point the valve plate closes the second air inlet. This indicates that the valve plate has rotated to the target position, thus ending the sub-cycle gas mixing regulation logic and simultaneously performing equipment drying treatment on the washing equipment.

[0117] During the drying process, the air intake fan can be turned on to draw outside air into the air intake duct, which then enters the washing chamber through the air inlet of the inner tank. After the outside air is drawn into the air intake duct by the air intake fan, the heating module in the air intake duct can heat the drawn outside air, thereby achieving the drying process of the equipment.

[0118] S408: If the opening degree of the first air inlet is less than the preset opening degree threshold, then execute the sub-cycle gas mixing regulation logic.

[0119] Specifically, when the opening of the first air inlet is less than the preset opening threshold, it indicates that the opening of the first air inlet has not been adjusted to the preset opening threshold. At this time, the process of periodically increasing the opening of the first air inlet and periodically decreasing the opening of the second air inlet based on the periodic gas mixing adjustment logic has not been completed. Therefore, the sub-cycle gas mixing adjustment logic continues to be executed until the opening of the first air inlet is greater than or equal to the preset opening threshold, at which point the sub-cycle gas mixing adjustment logic ends, and the equipment drying process begins.

[0120] This embodiment of the application executes the sub-cycle gas mixing adjustment logic corresponding to each sub-cycle within a preset cycle in sequence. The proportion of gas discharged from the washing chamber is gradually increased while the proportion of gas drawn in from the outside is gradually decreased. As time goes by, the dew point temperature of the gas discharged from the washing chamber continuously decreases. Therefore, increasing the proportion of gas discharged from the washing chamber and decreasing the proportion of gas drawn in from the outside can effectively maintain the dew point temperature of the gas discharged from the washing equipment below the initial ambient temperature. At the same time, gradually increasing the proportion of gas discharged from the washing chamber can still improve drying efficiency even when the humidity sensor fails, while preventing the gas discharged during the drying process from condensing on the wall surface of the corresponding external solid.

[0121] In one embodiment provided in this application, the exhaust device includes a first air inlet, a second air inlet, an exhaust outlet, and a valve plate. The first air inlet is connected to the washing chamber, and the second air inlet and the exhaust outlet are respectively connected to the outside air. The valve plate is used to control the opening degree of the first air inlet and / or the second air inlet of the exhaust device.

[0122] The above embodiments execute the second drying control logic to control the equipment drying process, including:

[0123] The control valve plate closes the second air inlet for drawing in outside gas and opens the first air inlet for discharging gas from the washing chamber. It also controls the air intake assembly of the washing equipment to input gas from the outside into the washing chamber and controls the exhaust assembly of the washing equipment to discharge the exhaust gas.

[0124] The first air inlet and the second air inlet are connected by an air duct. The first air inlet is used to discharge the gas discharged from the washing chamber. The second air inlet is used to draw in the gas drawn in from the outside of the washing chamber. The exhaust port is used to discharge the gas discharged from the washing chamber and / or the gas drawn in from the outside to the outside of the washing equipment.

[0125] When the maximum washing temperature is less than or equal to the set temperature threshold, it indicates that a low-temperature wash is being performed. At this time, the temperature inside the washing chamber is low, and the dew point temperature of the gas discharged from the washing chamber is low and lower than the initial ambient temperature. Therefore, the valve can be controlled to close the second air inlet for drawing in outside gas and open the first air inlet for discharging gas from the washing chamber, thus directly discharging the gas from the washing chamber. The gas discharged from the washing equipment at this time includes the gas discharged from the washing chamber but may not include the outside gas drawn in, because the dew point temperature of the gas discharged from the washing chamber is lower than the initial ambient temperature.

[0126] For example, such as Figure 2 As shown, the valve plate can be adjusted so that θ is 0°. The fan in the exhaust duct corresponding to the exhaust port will discharge the gas in the washing chamber. Maintain this state for 80 seconds. Then, turn on the air intake function of the inner tank air inlet. For example, turn on the air intake fan for 180 seconds to blow air into the washing chamber to dry the items in the washing chamber.

[0127] In the embodiments provided in this application, when the highest washing temperature is less than or equal to the set temperature threshold, it indicates that the washing is a low-temperature wash. At this time, the temperature inside the washing chamber is low, and the dew point temperature of the gas discharged from the washing chamber is low and lower than the initial ambient temperature. Therefore, the valve plate can be controlled to close the second air inlet for drawing in external gas and open the first air inlet for discharging gas from the washing chamber, thereby directly discharging the gas discharged from the washing chamber to accelerate the drying efficiency. At the same time, it avoids the gas discharged during the drying process of the washing equipment from condensing on the wall surface of the corresponding external solid of the washing equipment.

[0128] In one embodiment provided in this application, the washing device is a dishwasher;

[0129] The air intake assembly includes an inner liner air inlet, an air intake duct, and an air intake fan. The inner liner air inlet is connected to the air intake duct, and the air intake fan is used to draw outside air into the air intake duct and then into the washing chamber through the inner liner air inlet.

[0130] The air intake assembly and the exhaust device are respectively located on both sides of the inner tub of the dishwasher. The air intake of the air intake assembly is located on one side of the inner tub wall and is connected to the washing chamber in the inner tub. The first air intake is located on the other side of the inner tub wall and is connected to the washing chamber in the inner tub.

[0131] In all embodiments provided in this application, the washing device can be a dishwasher. A heating module can also be installed in the air inlet duct. The heating module heats the air drawn into the air inlet duct by the air inlet fan, and then the hot air enters the washing chamber through the inner tank air inlet, thereby drying the washing chamber. The heating module can be located between the air inlet fan and the inner tank air inlet, or it can be located on the opposite side of the air inlet fan's air intake direction.

[0132] The air intake assembly and exhaust device are respectively located on opposite sides of the inner tub of the dishwasher, or on adjacent sides of the inner tub, or on opposite sides of a gap between the inner tubs. The air intake assembly's inner tub air inlet is located on one side of the inner tub wall, and the first air inlet is located on the other side of the inner tub wall. Both the inner tub air inlet and the first air inlet are connected to the washing chamber within the inner tub.

[0133] In one embodiment provided in this application, after the above embodiments involve the air intake component of the washing equipment inputting gas from the outside into the washing chamber and the air exhaust component of the washing equipment discharging gas, the method further includes:

[0134] The air intake assembly is closed, and the control valve reduces the opening of the first air inlet to reduce the proportion of gas discharged from the washing chamber, and increases the opening of the second air inlet to increase the proportion of gas drawn in from the outside, until the opening of the first air inlet reaches a first preset value and the opening of the second air inlet reaches a second preset value.

[0135] This can be achieved by shutting down the intake fan to close the air intake assembly. Then, the control valve reduces the opening of the first air inlet to decrease the proportion of gas discharged from the washing chamber. Please refer to [reference needed]. Figure 2 The valve plate can be controlled to rotate counterclockwise by 35° to the bottom, thereby causing the opening of the first air inlet to reach a first preset value and the opening of the second air inlet to reach a second preset value. When the opening of the first air inlet reaches the first preset value, the opening of the first air inlet can be 55°, and when the opening of the second air inlet reaches the second preset value, the opening of the second air inlet can be 35°. The valve plate is controlled to rotate counterclockwise by 35° to the bottom and maintained in this state for 40 seconds. Here, 40 seconds can include the time during which the valve plate rotates counterclockwise by 35° to the bottom.

[0136] Because the air intake component of the washing equipment introduces gas from the outside into the washing chamber to dry the items in the washing chamber, the gas flow rate of the gas discharged from the washing chamber increases. When the air intake component is closed, the gas flow rate of the gas discharged from the washing chamber decreases. Therefore, the valve plate can be controlled to reduce the opening of the first air inlet to reduce the proportion of gas discharged from the washing chamber, and to increase the opening of the second air inlet to increase the proportion of gas drawn in from the outside. At the same time, the dew point temperature of the gas discharged from the equipment is reduced, so that the overall dew point temperature of the gas discharged from the washing equipment is lower than the initial ambient temperature.

[0137] In one embodiment provided in this application, after the opening degree of the first air inlet reaches a first preset value and the opening degree of the second opening reaches a second preset value, the method further includes:

[0138] After a first preset time period, the control valve increases the opening of the first air inlet and decreases the opening of the second air inlet until the opening of the first air inlet reaches a third preset value and the opening of the second air inlet reaches a fourth preset value. The third preset value is greater than the first preset value, and the fourth preset value is less than the second preset value.

[0139] The first preset time period can be set based on actual needs. Specifically, it can be 300 seconds. Here, 300 seconds can be recorded 30 times every 10 seconds, and the final count is used to determine the duration of the record.

[0140] After a first preset time period, the humidity and temperature of the gas discharged from the washing chamber are significantly reduced. Therefore, the dew point temperature of the gas discharged from the washing chamber is low, allowing for initial control of the valve to increase the opening of the first air inlet and decrease the opening of the second air inlet. For example, the valve can be controlled to rotate 20° clockwise towards the top, causing the opening of the first air inlet to reach a third preset value and the opening of the second air inlet to reach a fourth preset value. When the opening of the third air inlet reaches the third preset value, the opening of the first air inlet can be 75°, and when the opening of the second air inlet reaches the fourth preset value, the opening of the second air inlet can be 15°. The valve is controlled to rotate 20° clockwise towards the top and maintain this state for 20 seconds; here, 20 seconds can include the time it takes for the valve to rotate 20° clockwise towards the top.

[0141] As is easily understood, since the control valve plate in this embodiment increases the opening of the first air inlet and decreases the opening of the second air inlet, the third preset value of the first air inlet obtained after adjustment is greater than the first preset value, and the fourth preset value of the second air inlet obtained after adjustment is less than the second preset value.

[0142] In one embodiment provided in this application, after the opening degree of the first air inlet reaches a third preset value and the opening degree of the second air inlet reaches a fourth preset value, the method further includes:

[0143] After the second preset time period, the control valve adjusts the opening of the first air inlet to the preset opening threshold and closes the second air inlet for externally drawn-in air. The second preset time period can be 300 seconds. Similarly, this 300 seconds can be recorded 30 times every 10 seconds, and the final count is used to determine the duration of the hold.

[0144] After the initial control valve increases the opening of the first air inlet and decreases the opening of the second air inlet, the humidity and temperature of the gas discharged from the washing chamber are further reduced, resulting in a further decrease in the dew point temperature of the gas discharged from the washing chamber. Therefore, after a second preset time period, the control valve can adjust the opening of the first air inlet to a preset opening threshold and close the second air inlet for externally drawn-in gas. When the opening of the first air inlet is greater than or equal to the preset opening threshold, it indicates that the first air inlet is fully open. At this time, the gas discharged from the washing chamber can be fully discharged, thereby improving the drying efficiency.

[0145] For example, the valve plate can be controlled to rotate clockwise 15° to the top, thereby making the opening of the first air inlet reach 90° and the opening of the second air inlet 0°. The valve plate is controlled to rotate clockwise 15° to the top and maintained in this state for 20 seconds; here, 20 seconds can include the time it takes for the valve plate to rotate clockwise 15° to the top.

[0146] In one embodiment provided in this application, after the control valve plate adjusts the opening degree of the first air inlet to the opening degree threshold and closes the second air inlet for externally drawn-in gas in the above embodiment, the method further includes:

[0147] The system detects whether rinse aid is used in the washing mode and activates the air intake assembly. If rinse aid is used in the washing mode, the washing chamber is air-dried; if rinse aid is not used in the washing mode, the washing chamber is dried.

[0148] The main function of rinse aid is to assist in drying tableware and reduce water residue, thus making the tableware cleaner and shinier. It works by altering the surface tension of the tableware, making it less likely for water droplets to adhere, thereby reducing water stain formation. At the same time, rinse aid accelerates water evaporation during the drying process, helping the tableware achieve a faster drying effect. Rinse aid is also known as a rinsing agent or a brightening agent.

[0149] When rinse aid is used in the washing mode, its presence accelerates water evaporation during the drying process. In this case, the air intake fan can be used directly to dry the items in the washing chamber, avoiding the need to use the heating module to heat the air blown by the air intake fan, thus saving energy.

[0150] Specifically, the air intake fan can be turned on to dry the items in the washing chamber, and this state can be maintained for 300 seconds until the drying control process of the equipment ends. Similarly, the 300 seconds can be recorded 30 times every 10 seconds, and the final count can be used to determine the duration of the drying.

[0151] When rinse aid is not used in the washing mode, it is necessary to accelerate the evaporation of water during the drying process. At this time, while using the air intake fan to dry the items in the washing chamber, a heating module is needed to heat the air blown by the air intake fan to achieve the drying of the items in the washing chamber until the drying control process of the equipment ends.

[0152] In the embodiments provided in this application, it is detected whether rinse aid is used in the washing mode. Since rinse aid can accelerate the evaporation of water during the drying process, the presence of rinse aid accelerates the evaporation of water during the drying process. At this time, it is possible to avoid using the heating module to heat the air blown by the air intake fan, thereby saving energy. When rinse aid is not used in the washing mode, it is necessary to accelerate the evaporation of water during the drying process. At this time, while using the air intake fan to dry the items in the washing chamber, it is necessary to use the heating module to heat the air blown by the air intake fan in order to achieve the drying of the items in the washing chamber.
