Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of clothing processing equipment, and in particular to a method for determining operating parameters, a clothing processing equipment, and a storage medium. Background Art

[0002] With the development of smart home appliances, a wide variety of clothing handling devices have emerged, including washing machines, dryers, and washer-dryers. Clothes drying is becoming increasingly popular, effectively solving the problem of drying clothes in bad weather, dealing with dirty clothes after washing, and preventing damage to clothes caused by natural drying.

[0003] The clothes processing equipment uses the fan to suck in or blow fresh cold air from outside into the clothes processing equipment. The cold air is converted into dry hot air after heat exchange with the heat exchange device, and then is discharged from the body after heat exchange with the clothes tumbling in the drum. The moisture in the clothes in the drum is gradually evaporated under the action of the dry hot air, achieving rapid drying.

[0004] However, existing clothes processing equipment has a relatively simple control over the clothes drying process. For example, fixed operating parameters are used throughout the entire process, which makes the drying process single, resulting in low drying efficiency and drying energy efficiency. Summary of the Invention

[0005] The main technical problem solved by the embodiments of the present application is to provide a method for determining operating parameters, a clothing processing device and a storage medium, which can effectively improve the drying efficiency and drying energy efficiency of the clothing processing device.

[0006] In a first aspect, an embodiment of the present application provides a method for determining operating parameters, which is applied to a clothes processing device, comprising:

[0018] In the heating and drying stage, f=(a×W / W m -b×T / T m )×F+k1;

[0019] In the constant speed drying stage, f=(d×W / W m +e×Rh / Rh m )×F+k2;

[0020] In the drying stage of falling speed, f=(g×Rh / Rh m -j×T / T m )×F+k3;

[0021] Among them, f is the operating parameter, F is the rated parameter, W is the weight, W m is the rated weight, T is the temperature, T m is the drying target temperature, R is the humidity, Rh m is the drying target humidity, a, b, d, e, g and j are weight coefficients, and a>b>0, d>0, e>0, g>0, j>0, k1, k2 and k3 are all constants.

[0022] In some embodiments, the aforementioned step of obtaining the drying stage of the drying process includes:

[0023] Determine the drying stage of the drying process according to the temperature and humidity of the object to be dried.

[0024] In some embodiments, the above-mentioned step of determining the drying stage of the drying process according to the temperature and humidity of the object to be dried includes:

[0025] If the temperature is lower than the drying target temperature, it is determined that the drying process is in the heating and drying stage;

[0026] If the humidity is greater than the drying target humidity of the preset multiple, it is determined that the drying process is in the constant speed drying stage, wherein the preset multiple is greater than 1;

[0027] If the humidity is greater than the drying target humidity and less than or equal to a preset multiple of the drying target humidity, it is determined that the drying process is in the speed reduction drying stage.

[0028] In some embodiments, the laundry processing apparatus includes a drum and a heat exchange device in communication with the drum, and the operating parameters include a rotational speed of the drum and / or an output power of the heat exchange device.

[0029] In some embodiments, the heat exchange device includes a compressor and a fan, and the operating parameters include the operating frequency of the compressor and / or the speed of the fan.

[0030] In some embodiments, the heat exchange device includes a heating wire and a fan, and the operating parameters include the power of the heating wire and / or the speed of the fan.

[0039] In a third aspect, an embodiment of the present application provides a computer-readable storage medium, which stores computer-executable instructions, and the computer-executable instructions are used to enable a computer device to execute the method in the first aspect.

[0040] The beneficial effects of the embodiments of the present application are as follows: Unlike the prior art, the method for determining operating parameters provided by the embodiments of the present application is applied to a clothing processing device. The method obtains the drying stage of the drying process and the temperature, humidity, and weight of the items to be dried. The drying stages include a rising temperature drying stage, a constant speed drying stage, or a falling speed drying stage. The operating parameters of the clothing processing device are then determined based on the drying stage, temperature, humidity, and weight. In this embodiment, the corresponding operating parameters are determined for each drying stage. On the one hand, the corresponding operating parameters are determined for each drying stage so that the heat exchange provided to the items to be dried under these operating parameters meets the required heat for the drying stage without waste.

The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0051] In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0052] See also Figure 1 , Figure 1 Schematic diagram of a clothing processing device. In some embodiments, the clothing processing device may be a dryer or a washer-dryer. The clothing processing device 100 includes a housing 10, an outer drum 20, a drum 30, a heat exchange device 40, and a drive motor 50. The outer drum 20, the drum 30, the heat exchange device 40, and the drive motor 50 are housed within the housing 10. The drum 30 is a generally hollow cylindrical structure, disposed within the outer drum 20 and capable of rotating relative to the outer drum 20. The drive motor 50 is used to drive the drum 30 to rotate, which in turn drives the drying items contained within the drum 30 to rotate.

[0053] The heat exchange device 40 is disposed in the space between the housing 10 and the outer drum 20 and is connected to the drum 30 via a pipe. The drum 30, the heat exchange device 40, and the pipe form a gas circulation circuit. The heat exchange device 40 includes a pneumatic module 41 and a heating module 42.

[0054] The heating module 42 is arranged in the gas circulation circuit of the clothing processing device 100 to heat the air and turn it into dry hot air. In some embodiments, the heating module 42 can be a heating wire or a heat pump system, and no limitation is imposed on the heating module 42 herein. The heat pump system can include a compressor, a condenser and an evaporator. The compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, which is then cooled and dissipated by the condenser to become a liquid refrigerant. The liquid refrigerant flows into the evaporator and evaporates into a gaseous refrigerant, which can be compressed again by the compressor. The refrigerant is circulated through a gas-liquid phase change in the heat pump system. When passing through the condenser, it is cooled and dissipated, thereby heating the air in the gas circulation circuit and turning it into dry hot air.

[0055] The pneumatic module 41 is disposed within the duct of the laundry processing apparatus 100 and may be an air pump or a fan. The pneumatic module 41 is not limited herein. In some embodiments, the pneumatic module 41 is an air pump that extracts air from the drum 30, creating a negative pressure within the drum 30. This allows hot, dry air heated by the heating module 42 to enter the drum 30 through the air inlet, exchange heat with the laundry, and remove moisture from the laundry. The hot, moist air then exits the drum 30 through the air outlet. This cycle continues, allowing the laundry to be dried quickly. In some embodiments, the pneumatic module 41 is a fan that pumps air into the air circulation circuit. The heating module 42 heats the air to generate hot, dry air, which then enters the drum 30 and exchanges heat with the laundry, evaporating moisture from the laundry.

[0056] In some embodiments, in order to prevent a large amount of hot and humid air from being directly discharged into the house, a condenser and a condensing fan (not shown) are set at the air outlet. The hot and humid air passes through the condenser, and the condensing fan cools the condenser, so that the temperature and humidity of the hot and humid air are reduced when passing through the condenser, and it becomes an airflow that meets the indoor environment.

[0057] Some clothing processing devices known to the inventors of the present application have relatively simple control over the clothing drying process. For example, fixed operating parameters are used throughout the entire process, which makes the drying process single, resulting in low drying efficiency and drying energy efficiency.

[0058] For example, in the solution disclosed in patent application CN202011111012.3, the drying control method of the drying system includes: obtaining the actual humidity Rh of the drying chamber during the operation of the fan; determining the operating frequency f of the compressor based on the humidity range in which the actual humidity Rh is located; and controlling the compressor to operate at the operating frequency f; wherein the actual humidity Rh is directly proportional to the operating frequency f. However, this method only considers one input variable, "humidity." When the measured humidity is the same, but the load weight or temperature in the drying chamber is different, the calculated compressor operating frequency is not necessarily the optimal frequency, and thus, it is impossible to achieve high drying efficiency and drying energy efficiency.

[0059] To address the above-mentioned issues, embodiments of the present application provide a method for determining operating parameters, a clothing processing device, and a storage medium. This method, applied to the clothing processing device, obtains the drying stage of the drying process and the temperature, humidity, and weight of the items to be dried, wherein the drying stage includes a rising drying stage, a constant drying stage, or a falling drying stage. The operating parameters of the clothing processing device are then determined based on the drying stage, temperature, humidity, and weight. In this embodiment, corresponding operating parameters are determined for each drying stage. On the one hand, the corresponding operating parameters are determined for each drying stage so that the heat exchange provided to the items to be dried under these operating parameters meets the required heat for drying during the drying stage without waste. On the other hand, within each drying stage, the effects of the temperature, humidity, and weight of the items to be dried on the heat exchange requirement are refined, and corresponding operating parameters are determined so that the heat exchange provided to the items to be dried under these operating parameters is sufficient, wasteful, and efficient. Consequently, the drying efficiency and energy efficiency of the clothing processing device can be effectively improved.

[0060] As can be understood from the foregoing, the method for determining operating parameters provided in the embodiments of the present application can be implemented by various types of electronic devices with processing capabilities, such as a controller of a clothing processing device or other devices with computing and processing capabilities. The other devices with computing and processing capabilities can be smart terminals that are communicatively connected to the clothing processing device.

[0061] The following describes the method for determining operating parameters provided by the embodiment of the present application in conjunction with the exemplary application and implementation of the laundry processing device provided by the embodiment of the present application. Figure 2 , Figure 2 is a flow chart illustrating a method for determining operating parameters provided in an embodiment of the present application. It is understood that the method for determining operating parameters may be executed by one or more processors of a clothing processing device. This method for determining operating parameters is applicable to a clothing processing device. It is understood that the structure and operating principle of the clothing processing device are readily apparent from the above description and will not be further elaborated upon here.

[0062] like Figure 2As shown, the method S100 may specifically include the following steps:

[0063] S10: Obtain the temperature, humidity and weight of the object to be dried.

[0064] When drying clothes, the clothes are placed in the drum of the clothes processing equipment. As the drying progresses, heat exchange occurs between the clothes and the dry hot air, and the temperature, humidity and weight of the clothes change.

[0065] Here, the temperature, humidity and weight are collected when the objects to be dried are in the drum. Figure 3 The laundry processing apparatus 100 further includes a temperature sensor 60 disposed at the drum air outlet. The temperature sensor 60 can not only sense the temperature of the laundry to be dried in the drum 30, but can also indirectly sense the humidity of the laundry to be dried in the drum 30. In some embodiments, the laundry processing apparatus 100 further includes a temperature sensor and a humidity sensor (not shown) disposed at the drum air outlet, thereby respectively sensing the temperature and humidity of the laundry to be dried in the drum.

[0066] In some embodiments, see Figure 3 The laundry processing apparatus 100 further includes a drive motor 50 for driving the drum 30 to rotate. The drum 30 is coaxially arranged with the outer drum 20. The outer drum 20 has a mounting hole (not shown) at its bottom, which is fitted with a bearing seat (not shown). The bearing of the drive motor 50 extends from the bearing seat into the outer drum and is fixedly connected to the bottom of the drum 30. Thus, the rotation of the bearing of the drive motor 50 can drive the drum 20 to rotate.

[0067] In this embodiment, the weight of the objects to be dried can be indirectly sensed. For example, the aforementioned "obtaining the weight of the objects to be dried" includes: obtaining the current of the driving motor and determining the weight of the objects to be dried according to the current.

[0068] It is understandable that the load of the drive motor is proportional to the current. The greater the load, the greater the current. That is, the current of the drive motor has a corresponding relationship with the load. A current-load relationship table is pre-stored in the memory of the clothes processing device. In some embodiments, the weight of the drum is also pre-stored in the memory of the clothes processing device. When the drum contains the items to be dried, the current of the drive motor is obtained, and by looking up the current-load relationship table, the load (the total weight of the drum and the items to be dried) can be obtained, and then the weight of the drum is subtracted to obtain the weight of the items to be dried.

[0069] In this embodiment, based on the correspondence between the current of the driving motor and the load, the real-time weight of the clothes to be dried in the drum can be calculated by obtaining the current of the driving motor in real time, which can reduce the number of sensors in the clothing processing equipment and save hardware costs.

[0070] In some embodiments, to more accurately measure the weight of the laundry, the laundry processing device further includes a weighing module for weighing the laundry within the drum. For example, the weighing module can be located within the bearing housing to weigh the entire drum. Optionally, the weighing module is a pressure sensor located within the inner ring of the bearing housing. The pressure sensor can detect the pressure exerted by the entire drum on the motor bearings. Given a known drum weight and laundry contained within the drum, the processor of the laundry processing device can use this to determine the weight of the laundry within the drum. To further enhance measurement accuracy, in some embodiments, the pressure sensor can be located at the lower edge of the inner ring of the bearing housing.

[0071] Specifically, the aforementioned “obtaining the weight of the object to be dried” includes: obtaining a weighing value detected by a weighing module, and determining the weight of the object to be dried according to the weighing value.

[0072] It is understandable that the weighing value detected by the weighing module is the total weight of the drum and the objects to be dried. The drum weight pre-stored in the memory is called up, and the total weight minus the drum weight is the weight of the objects to be dried.

[0073] In this embodiment, the weight of the objects to be dried is sensed by the weighing module, so that the real-time weight of the objects to be dried can be accurately detected.

[0074] S20: Obtain the drying stage of the drying process, wherein the drying stage includes a temperature-increasing drying stage, a constant-speed drying stage, or a speed-decreasing drying stage.

[0075] Among them, the drying program refers to the drying process implemented by the clothing processing device. It is understandable that after the clothing processing device starts the drying program, within a certain period of time, the heat exchange device continuously blows dry hot air into the drum. At the same time, the drum rotates at high speed and continuously turns the items to be dried, so that the items to be dried are fully in contact with the dry hot air to achieve heat exchange, and the dry hot air takes away the moisture on the items to be dried. When the end condition is met, the drying program is terminated. In some embodiments, the end condition may be that the drying program is started for a preset time (for example, 30 minutes), that is, the drying action is maintained for a preset time (for example, 30 minutes). In some embodiments, the preset time can be set according to the volume, weight, and other properties of the items to be dried. In some embodiments, the end condition may be that the humidity of the items to be dried is lower than a humidity threshold. Here, the humidity threshold may be the humidity corresponding to when the clothes are drying.

[0076] It is understandable that as the drying process continues, the temperature and humidity of the objects to be dried continue to change. In order to make the drying process safe and reasonable, in some embodiments, the drying process is configured with drying processes related to temperature, humidity, and time. Figure 4 , Figure 4This is a schematic diagram of the drying process in some embodiments of the present application. Figure 4 The drying process is divided into three stages: a rising drying stage, a constant drying rate stage, or a falling drying rate stage. During the rising drying stage, the temperature of the material is rapidly raised to the target drying temperature. The target drying temperature is the temperature at which moisture in the material evaporates rapidly. Drying efficiency is higher at the target drying temperature. During the rising drying stage, the temperature of the material does not reach the target drying temperature, so moisture evaporation is insignificant and, therefore, the humidity change is minimal. The main purpose of the rising drying stage is to heat the material to the target drying temperature. During the constant drying rate stage, moisture is present on the surface of the material and continuously evaporates from it, resulting in a rapid decrease in humidity and minimal temperature change. During the falling drying stage, moisture is absent from the surface of the material, and the rate of moisture migration from the interior to the surface cannot keep up with the evaporation rate. Consequently, the surface temperature rises and the rate of humidity reduction (drying rate) gradually decreases. When the humidity drops to a certain level, cold air is applied to cool the material, simulating natural air drying.

[0077] Based on the temperature and humidity change characteristics of the objects to be dried at different drying stages, the drying stage of the drying process can be obtained.

[0078] In some embodiments, the aforementioned step S20 specifically includes: determining the drying stage of the drying process according to the temperature and humidity of the object to be dried.

[0079] Combine Figure 4 As can be seen from the temperature, humidity, and time variation curves in the figure, the temperature and humidity of the drying material vary across different drying stages, as do the speed and trend of temperature change, and the speed and trend of humidity change. Therefore, the drying stage of the drying process can be determined based on the temperature and humidity of the drying material. In some embodiments, the drying stage of the drying process can be determined based on the temperature change trend and humidity change rate. For example, if the temperature rises rapidly and the humidity does not change significantly, it indicates the drying stage is heating up; if the temperature remains steady and the humidity drops rapidly, it indicates the drying stage is constant; and if the temperature rises rapidly and the humidity drops at a decelerating rate, it indicates the drying stage is decreasing.

[0080] In some embodiments, the aforementioned "determining the drying stage of the drying program based on the temperature and humidity of the object to be dried" specifically includes: if the temperature is lower than the drying target temperature, determining that the drying program is in the heating drying stage; if the humidity is greater than a preset multiple of the drying target humidity, determining that the drying program is in the constant speed drying stage, wherein the preset multiple is greater than 1; if the humidity is greater than the drying target humidity and less than or equal to the preset multiple of the drying target humidity, determining that the drying program is in the speed decreasing drying stage.

[0081] The drying target temperature is the temperature at which the moisture in the object to be dried evaporates quickly. The object to be dried will have a higher drying efficiency at the drying target temperature. Therefore, if the temperature T is lower than the drying target temperature T m , it means the temperature is still rising. Therefore, it can be determined that the drying process is in the heating and drying stage.

[0082] The drying target humidity is the humidity when the object to be dried reaches a completely dry state. If the humidity Rh is greater than the preset multiple c of the drying target humidity Rh m When (ie Rh>c*Rh m ), the preset multiple c is greater than 1, indicating that the object to be dried is far from being completely dried. Therefore, it can be determined that the drying process is in the constant speed drying stage.

[0083] If the humidity Rh is greater than the drying target humidity Rh m And the drying target humidity Rh is less than or equal to the preset multiple c m When (ie Rh m <Rh≤c*Rh m ), indicating that the objects to be dried are not far from being completely dried. Therefore, it can be determined that the drying process is in the deceleration drying stage.

[0084] It is worth noting that the drying target temperature T m and drying target humidity Rh m It is an empirical value set by a person skilled in the art and stored in the memory of the clothes processing device. Thus, the clothes processing device can call the drying target temperature T m and drying target humidity Rh m The temperature and humidity of the object to be dried are compared with the real-time detected temperature and humidity to determine the drying stage of the drying process.

[0085] In this embodiment, the temperature and humidity of the object to be dried are respectively compared with the drying target temperature T m , Drying target humidity Rh m By comparing, you can accurately determine the drying stage of the drying program.

[0086] S30: Determine the operating parameters of the clothes processing equipment according to the drying stage and the temperature, humidity and weight of the clothes to be dried.

[0087] Operating parameters are indicators of the operating efficiency of laundry processing equipment and are related to the equipment's structure and operating principle. Because laundry processing equipment relies on the coordinated operation of the drum's rotation and the heat exchanger, turning the laundry and absorbing heat for evaporation, factors influencing the efficiency of laundry processing equipment include the drum's rotational speed and the heat exchanger's output power.

[0088] In some embodiments, the operating parameters include the rotational speed of the drum and / or the output power of the heat exchange device. It is understood that the greater the drum rotational speed, the higher the frequency of clothing flipping, which is conducive to heat exchange with dry hot air and can improve drying efficiency. The greater the output power of the heat exchange device, the higher the heat output per unit time, which can improve drying efficiency. In this embodiment, the operating parameters may include the rotational speed of the drum and the output power of the heat exchange device, thereby jointly adjusting the drying efficiency from two aspects. In some embodiments, the operating parameters may include the rotational speed of the drum or the output power of the heat exchange device, thereby unilaterally adjusting the drying efficiency.

[0089] In some embodiments, the heat exchange device includes a compressor and a fan. The compressor works in conjunction with the condenser and the evaporator as a heat pump system. The fan acts as a pneumatic module to blow outside air into the gas circulation circuit where the heat pump system is located. When the heat pump system is working, the heat dissipated by the condenser heats the air to obtain dry hot air. Thus, high-temperature gas can enter the drum. It can be understood that in this embodiment, the factors affecting the output power of the heat exchange device include the operating frequency of the compressor and the speed of the fan. The operating parameters may include the operating frequency of the compressor and / or the speed of the fan. In some embodiments, the fan can be replaced by an exhaust pump, and the operating parameters include the operating frequency of the compressor and / or the flow rate of the exhaust pump.

[0090] In some embodiments, the heat exchange device includes a heating wire and a fan. The heating wire is used to heat the gas. The fan serves as a pneumatic module to blow outside air into the gas circulation circuit where the heating wire is located. The heating wire heats the air to obtain dry hot air, which then enters the drum. It can be understood that in this embodiment, the factors affecting the output power of the heat exchange device include the power of the heating wire and the speed of the fan. The operating parameters include the power of the heating wire and / or the speed of the fan. In some embodiments, the fan can be replaced with an exhaust pump, and the operating parameters include the power of the heating wire and / or the flow rate of the exhaust pump.

[0091] In step S30, the operating parameters of the clothes handling device are determined based on four factors: the drying stage, the temperature, humidity, and weight of the clothes to be dried. That is, as these four factors are constantly changing throughout the drying process, the operating parameters of the clothes handling device are dynamically adjusted, allowing the clothes handling device to achieve a balanced drying efficiency and drying energy efficiency, effectively improving both.

[0092] Specifically, based on Figure 4As can be seen from the drying process shown, the rising drying stage is primarily aimed at raising the temperature of the item to the target drying temperature, requiring less heat. The constant drying stage, during which a large amount of moisture evaporates from the item, maintains the temperature near the target drying temperature, requiring more heat. The falling drying stage, during which relatively little moisture evaporates from the item, requires less heat. In other words, the heat required varies depending on the drying stage.

[0093] It is understandable that if the operating parameters of the clothes processing device are large, the heat supply will be excessive, resulting in heat waste and low drying efficiency; if the operating parameters of the clothes processing device are small, the heat supply will be insufficient, resulting in low drying efficiency. In order to ensure a reasonable heat supply for the clothes processing device, the corresponding operating parameters are determined in stages so that the exchange heat provided to the clothes to be dried under these operating parameters can meet the drying heat required during the drying stage without waste.

[0094] It is understandable that the temperature, humidity and weight of the object to be dried are factors that affect the heat demand for drying. The lower the temperature of the object to be dried, the more heat is required to reach the target drying temperature in the heating drying stage; the greater the humidity of the object to be dried, the more heat is required in the constant-rate drying stage; and the heavier the object to be dried, the more heat is required in each drying stage.

[0095] Therefore, in each drying stage, the effects of the temperature, humidity, and weight of the laundry on the heat exchange requirement are carefully considered, and corresponding operating parameters are determined to ensure that sufficient heat is provided to the laundry without waste, and that the heat exchange efficiency is high. This effectively improves the drying efficiency and energy efficiency of the clothes processing equipment.

[0096] In some embodiments, step S30 specifically includes: obtaining a preset function model corresponding to the drying stage, the preset function model being a multivariate function model of operating parameters with respect to temperature, humidity, and weight, and substituting temperature, humidity, and weight into the preset function model to calculate the operating parameters.

[0097] In this embodiment, the drying stage corresponds one-to-one to a preset function model. In the preset function model, the independent variables include temperature, humidity, and weight, and the dependent variables are operating parameters of the laundry processing device, such as the drum speed, fan speed, compressor frequency, or heating wire power.

[0098] The preset function models corresponding to each drying stage were developed by the inventors of this application using extensive experimental data. After obtaining the preset function models corresponding to each drying stage, they are stored in the memory of the clothing processing device. The clothing processing device can collect the temperature, humidity, and weight of the items to be dried at a preset frequency, determine the drying stage, and invoke the corresponding preset function model. The current temperature, humidity, and weight are substituted into the preset function model to calculate the corresponding operating parameters. The various modules of the clothing processing device are then controlled to operate according to the corresponding operating parameters.

[0099] In this embodiment, by pre-establishing a preset function model for each drying stage, the collected temperature, humidity, and weight are substituted into the preset function model corresponding to the drying stage to calculate the operating parameters. Because this preset function model is a multivariate function model of temperature, humidity, and weight established based on experimental data, the heat exchange provided to the clothes to be dried under these operating parameters is sufficient, wasteless, and highly efficient. This effectively improves the drying efficiency and energy efficiency of the clothes handling device.

[0100] In some embodiments, in the preset function model, when the drying stage is a temperature-increasing drying stage, the operating parameter is positively correlated with the weight and negatively correlated with the temperature.

[0101] In the heating and drying stage, the main task is to quickly heat the material to be dried to the target drying temperature T m , so that the object to be dried is at the drying target temperature T m In the drying stage, the temperature T of the object to be dried is negatively correlated with the operating parameters. It can be understood that the higher the temperature T of the object to be dried, the faster it will be when the temperature is raised to the target drying temperature T. m The less heat is needed, the lower the temperature is. Therefore, when the temperature rises, the operating parameters can be adjusted appropriately to avoid wasting heat and improve energy efficiency. In this heating and drying stage, the weight of the objects to be dried is positively correlated with the operating parameters. It can be understood that the heavier the weight of the objects to be dried, the more objects to be dried. When the temperature rises to the target drying temperature T m The more heat is required, the heavier the weight is, and the operating parameters can be appropriately increased to improve the drying efficiency.

[0102] When the drying program is started, during the heating and drying stage, the weight of the items to be dried remains roughly unchanged. As the temperature of the items to be dried increases, the operating parameters will gradually decrease. For example, the compressor starts at a higher frequency, and as the temperature increases, the compressor frequency gradually decreases.

[0103] In this embodiment, by setting the operating parameters of the heating and drying stage to be positively correlated with the weight and negatively correlated with the temperature, the clothing processing equipment can provide the clothes to be dried with heat corresponding to the weight under these operating parameters for rapid heating, thereby improving the drying efficiency; at the same time, the heat provided is adapted to the temperature, which can reduce heat waste and improve drying energy efficiency.

[0104] Depend on Figure 4 It can be seen that in the heating and drying stage, the temperature of the object to be dried is quickly heated to the target drying temperature T m , less water evaporates, and the humidity remains high with minimal fluctuations. The weight of the items being dried is similar to their initial weight. It's understandable that the temperature of the items before they are placed in the drum is close to the ambient temperature, which has little impact on the heat required for heating. The weight of the items has a greater impact on the heat required for heating.

[0105] To quickly heat the dried items and improve drying efficiency, in some embodiments, during the heating and drying phase, the influence of weight on operating parameters is set to be greater than the influence of temperature on the operating parameters. That is, in the preset function model corresponding to the heating and drying phase, weight is weighted more heavily than temperature. This prioritizes the impact of weight on operating parameters, which aligns with actual conditions and makes the preset function model for the heating and drying phase more reasonable.

[0106] In some embodiments, in the preset function model, when the drying stage is a constant-speed drying stage, the operating parameter is positively correlated with the weight and positively correlated with the humidity.

[0107] During the constant speed drying stage, the temperature is maintained at the target drying temperature T m Near the drying temperature, moisture on the dried items evaporates rapidly, rapidly reducing their humidity Rh. Due to the large amount of water evaporated, the weight of the items also decreases rapidly. It's understandable that the heavier and more humid the items are, the further they are from being completely dried, requiring more heat for evaporation. The lighter and less humid the items are, the closer they are to being completely dried. Excessive heat supply at this point will result in wasted heat and lower drying efficiency. Therefore, during the constant-rate drying phase, operating parameters are set to be positively correlated with weight and humidity to meet heat requirements.

[0108] In the constant speed drying stage, as the drying time progresses, the weight and humidity of the objects to be dried continue to decrease, and the operating parameters also gradually decrease, such as the frequency of the compressor.

[0109] In this embodiment, by setting the operating parameters of the constant-speed drying stage to be positively correlated with the weight and the humidity, the clothing processing equipment can provide the clothes to be dried with heat that is appropriate to the weight and humidity for evaporating moisture under these operating parameters without wasting heat, thereby taking into account both drying efficiency and drying energy efficiency.

[0110] In some embodiments, in the preset function model, when the drying stage is the speed-down drying stage, the operating parameter is positively correlated with humidity and negatively correlated with temperature.

[0111] During the drying stage, the humidity has dropped to c*Rh m (preset multiple of drying target humidity), there is no moisture on the surface of the object to be dried, and the speed of moisture moving from the inside to the surface cannot keep up with the evaporation rate of moisture on the surface of the object to be dried. The evaporation rate of moisture is slow, and heat accumulates in the object to be dried, so its humidity slowly decreases and the temperature rises rapidly. It can be understood that when the humidity of the object to be dried is higher and the temperature is lower, it means that more heat is needed for moisture evaporation; when the humidity of the object to be dried is lower and the temperature is higher, it means that most of the moisture has evaporated, heat accumulates in the object to be dried, and the evaporation efficiency is low. If more heat is supplied at this time, it will cause energy waste and low drying energy efficiency. Therefore, in the deceleration drying stage, the operating parameters are set to be positively correlated with humidity and negatively correlated with temperature to conform to the drying mechanism, reduce energy waste, and effectively increase energy efficiency.

[0112] In the deceleration drying stage, as the drying time progresses, the humidity of the objects to be dried gradually decreases and the temperature gradually increases. As a result, the operating parameters will gradually decrease, such as the frequency of the compressor.

[0113] In this embodiment, by setting the operating parameters of the deceleration drying stage to be positively correlated with humidity and negatively correlated with temperature, the clothing processing equipment can provide heat that is adapted to the humidity and temperature for the clothes to be dried under these operating parameters so that the internal moisture can evaporate slowly, thereby reducing heat waste and improving drying energy efficiency.

[0114] In some embodiments, the preset function model includes:

[0115] In the heating and drying stage, f=(a×W / W m -b×T / T m )×F+k1;

[0116] In the constant speed drying stage, f=(d×W / W m +e×Rh / Rh m )×F+k2;

[0117] In the deceleration drying stage, f=(g×Rh / Rh m -j×T / Tm )×F+k3;

[0118] Among them, f is the operating parameter, F is the rated parameter, W is the weight, W m is the rated weight, T is the temperature, T m is the drying target temperature, R is the humidity, Rh m is the drying target humidity, a, b, d, e, g and j are weight coefficients, and a>b>0, d>0, e>0, g>0, j>0, k1, k2 and k3 are all constants.

[0119] In this embodiment, the operating parameter f can be the rotation speed of the drum, the rotation speed of the fan, the frequency of the compressor, or the power of the heating wire. The rated parameter F corresponds to the type of the operating parameter f. The rated parameter F is the ideal value set by the clothing processing device when it leaves the factory and is stored in the memory. The drying target temperature T m , Drying target humidity Rh m and rated weight W m Alternatively, they may be set at the factory and stored in the memory. The temperature T, weight W, and humidity R are detected in real time at a certain frequency during the drying process.

[0120] During the heating and drying phase, the weight a for weight, the weight b for temperature, and the constant k1 are obtained by fitting extensive experimental data. Here, a>b>0. For example, a can be 0.8 and b can be 0.2. In some embodiments, the constant k1 is a correction or compensation value, the value of which can be determined based on the volume of the drum. During the heating and drying phase, the humidity of the dried material remains at a high value with minimal fluctuations. In this embodiment, the humidity weight is set to 0 to prevent humidity from interfering with operating parameters.

[0121] In the constant-speed drying stage, the weight d of weight, the weight e of humidity and the constant k2 are obtained by fitting a large amount of experimental data. Among them, d>0, e>0, for example, d can be 0.4, and e can be 0.5. In some embodiments, the constant k2 is a correction or compensation value, and its size is determined according to the category and material of the items to be dried. For example, the more difficult the items are to dry, such as pure cotton products, thicker cotton clothes or larger quilt covers, the larger the k2. In this embodiment, when the clothing processing device starts the drying program, it obtains the category and material of the items to be dried through a button or interactive interface to determine the k2 in the preset function model corresponding to the constant-speed drying stage. Based on the temperature in the constant-speed drying stage being maintained at the drying target temperature T m In this embodiment, the weight of the temperature is set to 0 to prevent the temperature from interfering with the operating parameters.

[0122] In the deceleration and drying stage, the weight g of humidity, the weight j of temperature and the constant k3 are obtained by fitting a large amount of experimental data. Wherein, g>0, j>0, for example, g can be 0.3, and j can be 0.7. In some embodiments, the constant k3 is a correction or compensation value, which can be determined according to the temperature resistance of the object to be dried. If the temperature resistance of the object to be dried is poor (such as chemical fiber products), the constant k3 is small. If the temperature resistance of the object to be dried is good (such as pure cotton products), the constant k3 can be appropriately increased. In this embodiment, when the clothing processing device starts the drying program, it obtains the category and material of the object to be dried through a button or an interactive interface to determine the temperature resistance, and then determines the corresponding k3. Based on the fact that the object to be dried is close to the drying state in the deceleration and drying stage, the weight change is not obvious. In this embodiment, it is equivalent to setting the weight of the weight to 0 to prevent the weight from interfering with the operating parameters.

[0123] In this embodiment, each drying stage adopts a different preset function model, and the preset function model assigns different weights to the weight ratio, humidity ratio and temperature ratio, so that the operating parameters are more reasonable and can take into account both drying efficiency and drying energy efficiency.

[0124] In summary, the method for determining operating parameters provided in an embodiment of the present application is applied to a clothing processing device. This method obtains the drying stage of the drying program and the temperature, humidity, and weight of the items to be dried, wherein the drying stage includes a rising drying stage, a constant drying stage, or a falling drying stage. The operating parameters of the clothing processing device are then determined based on the drying stage, temperature, humidity, and weight. In this embodiment, the corresponding operating parameters are determined in stages for each drying stage. On the one hand, the corresponding operating parameters are determined for each drying stage so that the heat exchange provided to the items to be dried under these operating parameters meets the required heat for drying during the drying stage without waste. On the other hand, within each drying stage, the effects of the temperature, humidity, and weight of the items to be dried on the heat exchange requirement are refined, and the corresponding operating parameters are determined so that the heat exchange provided to the items to be dried under these operating parameters is sufficient, wasteless, and has high heat exchange efficiency. Therefore, the drying efficiency and energy efficiency of the clothing processing device can be effectively improved.

The operating parameters of the clothing processing device are then determined based on the drying stage, temperature, humidity, and weight.

[0128] In this embodiment, operating parameters are determined for each drying stage. On the one hand, these parameters are determined for each drying stage, ensuring that the heat exchanged for the laundry under these parameters meets the required heat requirements for drying clothes during the drying stage without wasting heat. On the other hand, the effects of the temperature, humidity, and weight of the laundry on the heat exchange requirements are carefully considered for each drying stage, and corresponding operating parameters are determined to ensure that the heat exchanged for the laundry under these parameters is sufficient, wasteful, and efficient. This effectively improves the drying efficiency and energy efficiency of the clothes handling device.
