Description

Technical Field

[0001] This application relates to the field of clothing drying, specifically to a method, apparatus, dryer, and computer storage medium (computer-readable storage medium) for drying clothing. Background Technology

[0002] As people's living standards improve, they have higher requirements for clothing, food, housing and transportation. In order to meet people's living needs, household appliances with drying functions have been designed and used, including dry cleaning combos or dryers.

[0003] Taking a clothes dryer as an example, a clothes dryer is a household cleaning appliance that uses electric heating to evaporate and dry the moisture in washed clothes in a timely manner. Existing clothes dryers mainly determine the dryness by using a temperature sensor. The temperature sensor detects the temperature of the air outlet of the drum. When the air outlet temperature reaches the preset value and stabilizes, it is determined that the clothes are dry. This method has poor accuracy and may result in over-drying or under-drying, and cannot truly stop when the clothes are dry. Summary of the Invention

[0055] This application provides a method, apparatus, device, and computer storage medium for drying clothes, which will be described in detail below.

[0056] The clothing drying method in this embodiment of the invention is applied to a clothing drying device, which is installed in a dryer. The dryer is equipped with one or more processors, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the clothing drying method.

[0057] like Figure 1 As shown, Figure 1 This is a schematic diagram of a clothing drying process according to an embodiment of the present application. The clothing drying process in this embodiment includes a dryer 100 (the dryer 100 integrates a clothing drying device), and a computer storage medium in the dryer 100 that runs the clothing drying process to perform the clothing drying process steps.

[0058] Understandable Figure 1 The clothes dryer in the clothing drying scenario shown, or the device included in the clothes dryer, does not constitute a limitation on the embodiments of the present invention. That is, the number of devices or types of clothes dryers included in the clothing drying scenario, or the number or types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0059] In this embodiment of the invention, the clothes dryer 100 is mainly used for: obtaining a first temperature and a second temperature, wherein the first temperature is the temperature of the air flowing at the air outlet of the drum, and the second temperature is the temperature of the air inside the drum; determining the temperature of the target clothes inside the drum based on the first temperature and the second temperature; determining the drying state of the clothes based on the clothes temperature, wherein the drying state of the clothes includes a dried state and an undried state; and performing relevant operation processing on the clothes drying device based on the drying state of the clothes.

[0061] Furthermore, in the clothing drying process described in this application, the dryer 100 may be equipped with a display device, or the dryer 100 may not have a built-in display device but may communicate with an external display device 200. The display device 200 is used to output the results of the clothing drying process performed in the dryer. The dryer 100 can access a background database 300 (the background database may be located in the dryer's local storage or it may be located in the cloud), which stores information related to the clothing drying process.

[0062] It should be noted that, Figure 1 The schematic diagram of the clothing drying process shown is merely an example. The clothing drying process described in the embodiments of the present invention is intended to more clearly illustrate the technical solutions of the embodiments of the present invention and does not constitute a limitation on the technical solutions provided by the embodiments of the present invention.

[0063] Based on the above-mentioned scenario of clothing drying treatment, an embodiment of the clothing drying treatment method is proposed.

[0064] like Figure 2 As shown, Figure 2 This is a schematic flowchart of one embodiment of the clothing drying method in this application, which includes steps 201-204:

[0065] 201, obtain the first temperature and the second temperature.

[0066] The clothing drying method in this embodiment is applied to a clothing drying device, which includes a drum. The drying device is installed in a dryer. In this embodiment, the dryer is used as the execution subject for illustration.

[0067] The dryer obtains a first temperature and a second temperature from two temperature sensors at different locations. The first temperature is the temperature of the air flowing at the drum outlet, which is usually higher than the temperature of the clothes inside the drum. The second temperature is the temperature of the still air inside the drum, which is usually lower than the temperature of the clothes inside the drum. In other words, the first temperature is usually higher than the second temperature.

[0068] like Figure 3 As shown, Figure 3 This is a schematic diagram of an embodiment of the clothes drying method in this application, showing the setup of two sensors. The dryer indirectly detects the actual temperature of the clothes using a first temperature sensor 110 and a second temperature sensor 120 to improve the accuracy of temperature detection. Specifically, the first temperature sensor 110 is located at the air outlet of the drum 130 to detect the temperature of the flowing air at the outlet; the second temperature sensor 120 is located in the housing 140 and communicates with the drum 130 (where airflow is minimal, essentially non-flowing), to detect the temperature of the non-flowing air inside the drum. It is understood that during actual operation of the dryer, the temperature sensed by the first temperature sensor will be higher than the temperature of the clothes, while the temperature sensed by the second temperature sensor will be lower. Therefore, to accurately calculate the actual surface temperature of the clothes, the first and second temperatures sensed by the first and second temperature sensors are fitted to obtain the clothes temperature. Then, the rate of change of the clothes temperature is used to feedback the degree of dryness. When the rate of change of the clothes temperature meets a set condition, the drying program is shut off after determining that the clothes have reached the drying state, thereby achieving accurate determination of clothes dryness. Specifically:

[0069] 202. Determine the clothing temperature of the target clothing inside the drum based on the first temperature and the second temperature.

[0070] In this embodiment, during the actual operation of the dryer, the temperature sensed by the first temperature sensor will be higher than the temperature of the clothes, and the temperature sensed by the second temperature sensor will be lower than the temperature of the clothes. Therefore, in order to accurately calculate the actual temperature of the clothes surface, the dryer fits the first temperature and the second temperature to determine the temperature of the clothes. In this embodiment, the dryer does not specifically limit the fitting method of the first temperature and the second temperature, for example:

[0071] Implementation Method 1: A preset temperature coefficient mapping table is used in the dryer. The preset temperature coefficient mapping table contains a first temperature coefficient and a second temperature coefficient corresponding to different temperature ranges. In this embodiment, the temperature coefficients can be set according to the fan speed and heating temperature of the heating device in the dryer during drying. The dryer queries the preset temperature coefficient mapping table to obtain the first temperature coefficient corresponding to the first temperature and the second temperature coefficient corresponding to the second temperature. The dryer merges the first temperature and the first temperature coefficient, and merges the second temperature and the second temperature coefficient. The dryer averages the two merged temperature values ​​to obtain the temperature of the clothes.

[0072] Method 2: The dryer adds the first temperature and the second temperature together and takes the average to obtain the temperature of the clothes.

[0073] It should be noted that the clothing temperature obtained by fitting the first temperature and the second temperature in this embodiment is to improve the accuracy of clothing temperature assessment. For example, the dryer can collect historical clothing drying information and set a fitting curve for the first temperature and the second temperature. Alternatively, the dryer can combine different drying times or different clothing drying states to determine the first temperature coefficient of the first temperature and the second temperature coefficient of the second temperature, making the determined clothing temperature more accurate.

[0074] 203. Determine the drying state of the clothing based on the clothing temperature, wherein the drying state of the clothing includes a tumble-dried state and a undried state.

[0075] The clothes dryer determines the drying status of the clothes based on their temperature. The drying status includes both tumble-drying and undried states. In this embodiment, the clothes dryer determines the drying status specifically by:

[0076] 1. When the temperature of the clothing reaches a preset temperature threshold and remains there for a preset duration, or when the temperature change rate of the clothing reaches a preset change rate threshold, the clothing is determined to be in a drying state.

[0077] 2. If the temperature of the clothing does not reach the preset temperature threshold and the rate of change of the clothing temperature does not reach the preset rate of change threshold; or if the temperature of the clothing reaches the preset temperature threshold but does not last for the preset duration and the rate of change of the clothing temperature does not reach the preset rate of change threshold, then the clothing is determined to be in an undried state.

[0078] That is, in this embodiment, the preset temperature threshold, preset duration, and preset rate of change threshold are used to determine the drying state of the clothes; the preset temperature threshold in this embodiment can be determined according to the ambient temperature, drying method, etc., for example, the preset temperature threshold is set to 30℃; the preset duration refers to the critical value for determining the drying state of the clothes. If the duration for which the temperature of the clothes is higher than the preset temperature threshold exceeds the preset duration, the dryer determines that the clothes are in the drying state. For example, the preset duration is set to 10 minutes; the preset temperature rate of change refers to the critical value of the rate of change of the temperature of the clothes. Under normal circumstances, after the clothes reach the drying state, the rate of change of the temperature of the clothes will reach the preset temperature rate of change threshold.

[0079] The dryer compares the calculated temperature of the clothes with a preset temperature threshold, the duration for which the clothes temperature reaches the preset temperature threshold with a preset duration, or the rate of change of the clothes temperature with a preset rate of change threshold, in order to determine the drying status of the clothes.

[0080] When the temperature of the clothes reaches the preset temperature threshold and remains there for a preset duration, or when the temperature change rate of the clothes reaches the preset change rate threshold, the dryer determines that the clothes are in a drying state. Conversely, when the temperature of the clothes does not reach the preset temperature threshold and the temperature change rate of the clothes does not reach the preset change rate threshold, the dryer determines that the clothes are not in a drying state. Or, when the temperature of the clothes reaches the preset temperature threshold but does not remain there for a preset duration and the temperature change rate of the clothes does not reach the preset change rate threshold, the dryer determines that the clothes are not in a drying state.

[0081] 204. Based on the drying state of the clothing, perform relevant operations on the clothing drying device.

[0082] The dryer determines the remaining drying time based on the clothes' drying status. If the clothes are in the tumble-drying state, the dryer shuts off the drying program; if the clothes are not tumble-dried, the dryer calculates and displays the remaining drying time. In this embodiment, the method by which the dryer calculates the remaining drying time is not specifically limited; for example…

[0083] Method 1: The dryer determines the first remaining drying time based on the weight of the clothes, and the dryer determines the second remaining drying time based on the temperature of the clothes. The dryer then weights and combines the first and second remaining drying times to obtain the remaining drying time and outputs it.

[0084] Method 2: The dryer determines the drying program based on the temperature of the clothes, and calculates and displays the remaining drying time according to the drying stage corresponding to the drying program.

[0085] Understandably, the dryer also includes a gas-driven device 150 (fan or exhaust fan) and a heating device 160 (heat pump or heating element), as detailed above. Figure 3 As shown, the drying air can be either internal or external circulation. After the dryer determines that the clothes are not yet dried and the corresponding remaining drying time, it can also control the gas drive device and heating device to dry the target clothes according to the temperature and weight of the clothes until the clothes are in the dried state.

[0086] In this embodiment, the dryer fits the temperature of the clothes based on a first temperature and a second temperature, thereby determining the dryness of the clothes based on the temperature of the clothes, which improves the accuracy of the dryness judgment. Furthermore, the dryer performs the drying process based on the dryness of the clothes, so that the process stops as soon as the clothes are dry, thus reducing energy waste.

[0087] like Figure 4 As shown, Figure 4 This is a schematic flowchart of an embodiment of the clothing drying process in this application, illustrating the determination of clothing temperature. The clothing drying process includes steps 301-303:

[0088] 301, Determine the temperature difference between the first temperature and the second temperature.

[0089] 302, Obtain the corresponding first temperature coefficient and second temperature coefficient based on the temperature difference;

[0090] The dryer calculates the temperature difference between the first temperature and the second temperature. The magnitude of the temperature difference is affected by the gas drive device (fan or exhaust fan) and the heating device (heat pump or heating wire) in the dryer. The dryer obtains the corresponding first temperature coefficient and second temperature coefficient based on the temperature difference. By taking the temperature difference into account when determining the first temperature coefficient and the second temperature coefficient, the temperature of the clothes can be determined more accurately.

[0091] Specifically: The dryer queries a preset temperature coefficient mapping table to obtain the first and second temperature coefficients corresponding to the temperature difference; wherein, when the preset temperature difference is zero, the first temperature coefficient and the second temperature coefficient are the same; when the preset temperature difference is greater than zero, the first temperature coefficient is less than the second temperature coefficient. When the preset temperature difference is greater than zero, the dryer counts different drying conditions to obtain the first and second temperature coefficients under the corresponding temperature difference. For example, as the sensing temperature of the first temperature sensor gradually increases, the value of the first temperature coefficient is decreased and the value of the second temperature coefficient is increased to accurately calculate the temperature of the clothes. Furthermore, the higher the wind speed in the dryer, the smaller the value of the first temperature coefficient and the larger the value of the corresponding second temperature coefficient.

[0092] That is, a preset temperature coefficient mapping table is set in the dryer. The preset temperature coefficient mapping table stores the first temperature coefficient and the second temperature coefficient corresponding to different temperature differences. The dryer queries the preset temperature coefficient mapping table to obtain the first temperature coefficient and the second temperature coefficient corresponding to the temperature difference. When the preset temperature difference is zero, the first temperature coefficient and the second temperature coefficient are the same; when the preset temperature difference is greater than zero, the first temperature coefficient is less than the second temperature coefficient.

[0093] 303. Based on the first temperature and the first temperature coefficient, and the second temperature and the second temperature coefficient, the clothing temperature of the target clothing inside the drum is obtained; wherein, the clothing temperature T0 = K1*T1 + K2*T2, where T1 is the first temperature, K1 is the first temperature coefficient, T2 is the second temperature, and K2 is the second temperature coefficient.

[0094] The dryer combines a first temperature and a first temperature coefficient, and a second temperature and a second temperature coefficient to obtain the temperature of the target clothing inside the drum. The clothing temperature T0 = K1*T1 + K2*T2, where T1 is the first temperature, K1 is the first temperature coefficient, T2 is the second temperature, and K2 is the second temperature coefficient. For example, when the airflow speed is low (or the fan speed is low), the surface temperature of the clothing is close to the temperature sensed by the first or second temperature sensor. In this case, the reference weights K1 and K2 should be roughly equal, each around 0.5. When the airflow speed is high (or the fan speed is high), the temperature sensed by the first temperature sensor gradually increases. In this case, the reference weight K1 is decreased, and the reference weight K2 is increased to accurately calculate the clothing temperature. Furthermore, the higher the airflow speed, the lower the value of K1, and the higher the value of K2.

[0095] It is understood that, in this embodiment, the first temperature coefficient and the second temperature coefficient can be related to the temperature difference, and those skilled in the art can also set the first temperature coefficient and the second temperature coefficient according to the drying information of the dryer, for example, according to the fan speed or the drying program.

[0096] In this embodiment, the first temperature coefficient and the second temperature coefficient are processed to obtain the clothing temperature, making the clothing temperature more accurate, thereby obtaining the prepared clothing state and making the drying control more accurate.

[0097] Reference Figure 5 , Figure 5 This is a flowchart illustrating one embodiment of the clothing drying process for calculating the remaining drying time provided in this application.

[0098] In some embodiments of this application, step 204 involves performing relevant operational processes on the clothing drying device based on the clothing drying state. Specifically, steps 401-402 are as follows:

[0099] 401, determine that the clothes are in an undried state, and obtain the drying stage of the drying process, wherein the drying stage includes at least one of a heating drying stage, a constant speed drying stage, and a falling speed drying stage;

[0100] The dryer determines the clothes to be in an undried state, and obtains the current drying stage of the drying program. This drying stage includes at least one of a heating drying stage, a constant-speed drying stage, and a cooling drying stage. (Parameters) Figure 6 , Figure 6 This is a schematic diagram of a scenario in one embodiment of the clothing drying process provided in this application. Figure 6 The horizontal axis represents time, and the vertical axes of the two curves represent humidity and temperature, respectively. The humidity curve gradually decreases over time, while the temperature curve first increases, then balances out, and then rises again, decreasing at the end of the drying process. It should be noted that this embodiment uses curves to represent the relationship between time and clothing temperature, and time and clothing weight. The dryer can also use tables or other formats to represent the correlation between time and clothing temperature, and time and clothing weight.

[0101] 402, obtain the first remaining drying time corresponding to the weight of the target garment and the second remaining drying time corresponding to the temperature of the garment.

[0102] The dryer obtains the weight of the target clothing corresponding to the first remaining drying time, and the clothing temperature corresponding to the second remaining drying time. Figure 6 In this embodiment, the dryer can obtain the first remaining drying time corresponding to the weight of the clothes based on the moisture content time curve, and the dryer can obtain the second remaining drying time corresponding to the temperature of the clothes based on the temperature time curve.

[0103] 403, Obtain the first time coefficient and the second time coefficient corresponding to the drying stage;

[0104] The dryer contains a preset time coefficient mapping table, which includes a first time coefficient and a second time coefficient corresponding to different drying stages of the drying program. Specifically, when the drying program is in the heating drying stage, the first time coefficient is less than the second time coefficient; when the drying program is in the constant-speed drying stage, the first time coefficient is greater than the second time coefficient; and when the drying program is in the deceleration drying stage, the first time coefficient is equal to the second time coefficient. The dryer queries the preset time coefficient mapping table to obtain the first and second time coefficients corresponding to the drying stage.

[0105] 404. Based on the first remaining drying time and the first time coefficient, and the second remaining drying time and the second time coefficient, the remaining drying time is obtained.

[0106] The dryer adjusts the first remaining drying time according to a first time coefficient and the second remaining drying time according to a second time coefficient, and then merges the two adjusted remaining drying times to obtain the final remaining drying time. For example, the remaining drying time t0 = k1*t1 + k2*t2, where t1 is the first remaining drying time, k1 is the first time coefficient, t2 is the second remaining drying time, and k2 is the second time coefficient. Here, t1 is the first remaining drying time determined only by considering the weight of the clothes, t2 is the second remaining drying time determined only by considering the temperature of the clothes, k1 is a reference weight for the weight of the clothes, and k2 is a reference weight for the temperature of the clothes. For example, t1 can be estimated from the trend of changes in the weight of the clothes, and t2 can also be estimated from the trend of changes in the temperature of the clothes. It is understandable that the values ​​of the first and second time coefficients are related to the drying stage of the garment (including the heating drying stage, the constant speed drying stage, and the cooling drying stage). For example, in the heating drying stage, the change in the weight of the garment is not significant, but the change in the garment temperature is more significant. At this time, k1 has a smaller value, and k2 has a larger value. Similarly, in the constant speed drying stage, the change in the weight of the garment is more significant, but the change in the garment temperature is not significant.
