Description

Technical Field

[0001] This application relates to the field of electromechanical control, and more specifically, to a garment processing device. Background Technology

[0002] As people's living standards continue to improve, using garment processing equipment to process clothes is a common method of garment processing, such as garment washing, garment drying, and garment dry cleaning. The types of garments processed by garment processing equipment include, but are not limited to, T-shirts, jeans, cotton-padded clothes, and down jackets.

[0003] In related technologies, considering that clothing with fillings takes a long time to dry, clothing processing equipment usually preheats the clothes before drying to shorten the drying time. However, when heating the air inside the drum assembly, it is impossible to heat the air temperature evenly in all areas of the drum assembly. This can easily lead to the air temperature in some areas of the drum assembly not reaching the required preheating temperature, resulting in a decrease in the preheating effect. Summary of the Invention

[0004] To address the aforementioned technical problems, embodiments of this application provide a garment processing device.

[0005] According to an embodiment of this application, a clothing processing device is provided, comprising: a drum assembly for containing clothing to be dried and rotating under the drive of a motor; a drying assembly for drying the clothing contained in the drum assembly, including a drying duct, a fan, and a heating element, wherein the heating element heats the air in the drying duct, and the fan delivers the heated air in the drying duct to the drum assembly; and a controller configured to perform the following steps: acquiring a drying signal indicating that the clothing to be dried is to be dried; controlling the drying assembly to run multiple preheating cycles in response to the drying signal; and controlling the drying assembly to dry the clothing based on a constant temperature signal; wherein the constant temperature signal is used to indicate that the number of times the preheating cycle has been run has reached a preset number.

[0006] In the clothing processing equipment provided in the embodiments of this application, the drying component is controlled to run multiple preheating cycles in response to a drying signal until the number of cycles reaches a preset number. Then, a constant temperature signal is generated, and the drying component is controlled to dry the clothes to be dried based on the constant temperature signal. By running multiple preheating cycles and reaching the preset number of cycles, the temperature of the air in each area of ​​the drum component is stably and evenly controlled at the preheating temperature corresponding to the preheating cycle before drying is implemented, thereby improving the preheating effect corresponding to the preheating cycle and thus improving the drying performance of the clothing processing equipment.

[0007] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: in the preheating condition, the heating tube and the fan are started and run based on a first running time, and the temperature value inside the cylinder assembly is obtained; if the temperature value reaches a first preset temperature, the heating tube and the fan are stopped and the running count is incremented by one; conversely, when the running time reaches the first running time, the heating tube and the fan are stopped; when the duration of the heating tube and the fan being stopped reaches the shutdown duration, the step of starting the heating tube and the fan based on the first running time is executed, until the running count reaches the preset number, and the constant temperature signal is generated.

[0008] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: during the process of controlling the drying component to dry the clothes to be dried based on the constant temperature signal, the controller controls the motor to drive the drum component to rotate according to the operating parameters of the first drying condition, and controls the drying component to raise the temperature value of the drum component to the first drying temperature range corresponding to the first drying condition, so as to dry the fabric of the clothes to be dried; if the running time of the first drying condition reaches the standard time corresponding to the operating parameters, the controller controls the motor to drive the drum component to rotate according to the operating parameters of the second drying condition, and controls the drying component to raise the temperature value of the drum component to the second drying temperature range corresponding to the second drying condition, so as to dry the filling of the clothes to be dried; wherein, the minimum value of the second drying temperature range is greater than the maximum value of the first drying temperature range.

[0009] In the garment processing equipment provided in the embodiments of this application, the fabric of the garment to be dried can be dried in the first drying temperature range corresponding to the first drying condition, so that the fabric can be initially dried at a suitable drying temperature, thereby improving the temperature resistance of the fabric as the dryness of the fabric increases, and making the fabric less likely to be damaged during the tumbling drying process; the filling of the garment to be dried is further dried in the second drying temperature range corresponding to the second drying condition, which is higher than the first drying temperature range, so as to shorten the drying time.

[0011] In the clothing processing equipment provided in the embodiments of this application, the running time of the first drying condition and the second drying condition can be adjusted according to the weight value to dry clothes with different moisture contents in a targeted manner, thereby making the drying effect of the clothing processing equipment better and improving the user's satisfaction with the clothing processing equipment.

[0012] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: during the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the first drying condition, adjusting the operating parameters corresponding to the first drying condition according to the weight value, wherein the operating parameters include, but are not limited to, speed parameters and rotation-to-stop ratio parameters; during the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the second drying condition, adjusting the operating parameters corresponding to the second drying condition according to the weight value.

[0013] In the clothing processing equipment provided in the embodiments of this application, the working process of the first drying condition and the second drying condition can be adjusted according to the actual weight of the clothes to be dried, so as to further dry the clothes with different moisture contents in a targeted manner.

[0014] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: obtaining the dehydration speed when dehydrating the clothes to be dried; if the dehydration speed is greater than a preset high dehydration speed, then setting the standard duration corresponding to the operating parameters of the first drying condition and the second drying condition to a high-speed duration, wherein the high-speed duration is less than the standard duration; if the dehydration speed is less than a preset low dehydration speed, then setting the standard duration corresponding to the operating parameters of the first drying condition and the second drying condition to a low-speed duration, wherein the low-speed duration is greater than the standard duration.

[0015] In the clothing processing equipment provided in the embodiments of this application, the running time of the first drying condition and the second drying condition can be adjusted according to the dehydration speed of the clothes to be dried, so as to dry clothes with different moisture contents in a targeted manner, thereby making the drying effect of the clothing processing equipment better and improving the user's satisfaction with the clothing processing equipment.

[0016] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: during the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the first drying condition, adjusting the operating parameters corresponding to the first drying condition according to the dehydration speed, wherein the operating parameters include, but are not limited to, speed parameters and rotation-to-stop ratio parameters; during the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the second drying condition, adjusting the operating parameters corresponding to the second drying condition according to the dehydration speed.

[0017] In the clothing processing equipment provided in the embodiments of this application, the working process of the first drying condition and the second drying condition can be adjusted according to the dehydration speed of the clothes to be dried, so as to further dry the clothes with different moisture contents in a targeted manner.

[0018] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: during the process of obtaining the weight value of the clothes to be dried in the drum assembly, controlling the motor to drive the drum assembly to reach a first speed; obtaining the change amplitude of the back electromotive force and the decay rate of the oscillation frequency of the motor when the speed of the drum assembly drops from the first speed to 0; and determining the weight value of the clothes to be dried in the drum assembly based on the change amplitude of the back electromotive force and the decay rate of the oscillation frequency.

[0019] The clothing processing device provided in the embodiments of this application can calculate the weight of the clothes to be dried by the change amplitude of the back electromotive force and the decay rate of the oscillation frequency, making the obtained weight value less susceptible to signal interference and more accurate.

[0020] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: during the process of controlling the drying component to perform the preheating operation in response to the drying signal, the controller controls the motor to drive the drum assembly to rotate according to the operating parameters of the shaking operation, so as to disperse the clothes to be dried in the drum assembly.

[0021] In the clothing processing equipment provided in the embodiments of this application, the clothes to be dried in the drum assembly can be dispersed by shaking, thereby increasing the contact area between the clothes to be dried and the heated air after shaking, so as to improve the drying effect when drying the clothes to be dried in the subsequent process and shorten the overall drying time.

[0022] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: after controlling the drying component to dry the clothes to be dried based on the constant temperature signal, controlling the motor to drive the drum component to rotate according to the operating parameters of the cooling condition, and controlling the fan and the heating tube to stop running.

[0025] In the clothing processing equipment provided in the embodiments of this application, the speed and amplitude of the rotation of the drum assembly can be adjusted according to the weight value during the cooling process, so that the cooling area of ​​the clothes to be dried increases during the cooling process driven by the drum assembly, thereby shortening the cooling time.

[0026] In some embodiments of this application, based on the foregoing scheme, the controller is further configured to perform the following steps: during the process of controlling the motor to drive the cylinder assembly to rotate according to the operating parameters of the cooling condition, the temperature value inside the cylinder assembly is obtained; if the temperature value reaches the preset cooling temperature, the motor is controlled to stop running.

[0027] In the clothing processing device provided in the embodiments of this application, it is possible to determine whether the temperature value has reached the preset cooling temperature, thereby further ensuring that the temperature of the drum assembly surface and the temperature of the dried clothing surface are not likely to cause burns to the user.

[0036] Figure 1This is a schematic diagram of the structure of a garment processing device provided in an embodiment of this application. Garment processing equipment refers to equipment for processing garments, including but not limited to washing machines, dryers, and washer-dryer combos. Figure 1 As shown, the garment processing equipment 10 includes a housing 11, a drum assembly 12, a drying assembly 13, and a controller. Each component will be described below.

[0037] The drum assembly 12 is rotatably disposed in the housing 11 and is used to hold clothes to be dried. In order to drive the drum assembly 12 to rotate, the clothes handling equipment 10 also includes a motor 14 disposed on the housing 11, the output end of the motor 14 being connected to the drum assembly 12 so that the drum assembly 12 rotates under the drive of the motor 14.

[0038] A drying assembly 13 is disposed within the housing 11 and is used to dry the clothes to be dried contained in the drum assembly 12. The drying assembly 13 includes a drying air duct 15, a fan 16, and a heating element 17. The heating element 17 is disposed within the drying air duct 15 and is used to heat the air within the duct. The fan 16 is also disposed within the drying air duct 15 and is used to transport the heated air from the duct 15 into the drum assembly 12, thereby drying the clothes.

[0039] The controller is housed in enclosure 11 and is electrically connected to motor 14, fan 16, and heating element 17. The controller is configured to perform the following steps:

[0040] Acquire a drying signal to indicate that the clothes to be dried should be dried;

[0041] The drying unit is controlled to operate under multiple pre-heating conditions in response to the drying signal.

[0042] The drying components are controlled by a constant temperature signal to dry the clothes.

[0043] It should be noted that the garment processing equipment 10 is usually set with different operating conditions to process the clothes in the drum assembly 12, such as washing, rinsing, spin-drying, and drying. In order to obtain better washing results for different types of clothes after processing different types of clothes, the manufacturer will arbitrarily combine and arrange different operating conditions to obtain a variety of washing programs.

[0044] In the above process, after obtaining the drying signal, the controller controls the drying component to run multiple pre-heating cycles in response to the drying signal. The drying signal can be generated either by the controller determining that the previous pre-heating cycle has ended, or by the controller determining that the current washing program's washing effect is sufficient to dry the clothes.

[0045] It should be noted that, in order to shorten drying time and improve drying effect when drying clothes, the garment processing equipment 10 usually preheats the air inside the drum assembly 12 during the drying process to initially raise the air temperature. During the preheating process of the drying component 13 in the garment processing equipment 10, a temperature sensor is generally used to determine the degree of preheating. For example, when the temperature sensor detects that the air temperature inside the drum assembly 12 has reached the temperature required for preheating, the heating element 17 and the fan 16 are stopped, thereby completing the preheating process.

[0046] However, the heating of the air inside the cylinder assembly 12 by the drying component 13 is not uniform. If the temperature sensor is placed near the air outlet of the drying duct 15 in the drying component 13, the heating tube 17 may be shut off when the temperature sensor detects that the nearby temperature has reached the required preheating temperature. This could easily lead to the air temperature on the side of the cylinder assembly 12 away from the air outlet not reaching the required preheating temperature, thus reducing the preheating effect. Conversely, if the temperature sensor is placed away from the air outlet of the drying duct 15 in the drying component 13, the heating tube 17 may overheat and operate because the temperature near the temperature sensor may not reach the required preheating temperature for a long time. This could easily cause the heating tube 17 to trip and stop operating or be damaged and scrapped.

[0047] In the embodiments of this application, in order to stabilize the air temperature inside the drum assembly 12 after preheating, the drying assembly 13 can be controlled to dry the clothes to be dried based on a constant temperature signal after running the preheating condition multiple times. The constant temperature signal is used to indicate that the number of times the preheating condition has been run has reached a preset number, so that by running the preheating condition multiple times, the air temperature in each area inside the drum assembly 12 can reach the temperature required for preheating.

[0048] The controller generates a constant temperature signal by following these steps:

[0049] In the preheating condition, the heating tube and fan are started and run based on the first running time, and the temperature value inside the cylinder assembly is obtained;

[0050] If the temperature reaches the first preset temperature, the heating element and fan will stop running and the running count will be incremented by one. Conversely, when the running time reaches the first running time, the heating element and fan will stop running.

[0051] When the heating element and fan stop running for the duration of the shutdown, the process jumps to the step of controlling the heating element and fan to start running based on the first running time, until the preset number of runs is reached and a constant temperature signal is generated.

[0052] The first running time is the duration of a single run in the preheating mode, and the first preset temperature is the temperature value expected to be reached in the preheating mode. Both the first running time and the first preset temperature can be flexibly adjusted according to the specific situation of the clothes to be dried. For example, they can be adjusted according to the material, heat resistance temperature, or weight of the clothes to be dried; there are no restrictions here.

[0053] In the embodiments of this application, while the heating element and fan are started based on the first running time, if the temperature value inside the drum assembly reaches the first preset temperature, the heating element and fan are stopped. This is to prevent the temperature inside the drum assembly from becoming too high during the preheating process, which could cause some areas of the clothes to be dried to be dried prematurely, leading to further drying and damage in those areas during subsequent drying processes. Furthermore, after stopping the heating element and fan, the running count is incremented by one to indicate the number of times the air temperature inside the drum assembly has risen to the required preheating temperature during the preheating process.

[0054] Correspondingly, when the running time reaches the first running time, if the temperature value inside the cylinder assembly has not yet reached the first preset temperature, the heating tube and fan will be controlled to stop running to avoid the heating tube from overheating and causing it to trip and stop.

[0055] In the embodiments of this application, after each time the heating element and fan stop running, when the duration of the heating element and fan stop running reaches the downtime, the step of controlling the heating element and fan to start running based on the first running time can be executed to achieve repeated operation of the preheating condition.

[0056] The shutdown duration allows the heating element surface to cool down and the heated air inside the cylinder assembly to circulate, thus equalizing the air temperature in different areas of the assembly. The shutdown duration can be flexibly set as needed and is not limited here.

[0057] Through the above implementation method, when the number of preheating operation reaches the preset number, it indicates that the air inside the drum assembly has been heated multiple times under the preheating operation and has reached the required preheating temperature multiple times. This means that the temperature value of the air inside the drum assembly has been stably controlled at the first preset temperature corresponding to the preheating operation. Then, a constant temperature signal is generated. In the process of drying clothes by controlling the drying assembly based on the constant temperature signal, the accuracy of the temperature sensor can be improved. This avoids the temperature detected by the temperature sensor not keeping up with the actual temperature change of the air inside the drum assembly during the subsequent drying process, which would cause the heating tube to overheat and stop.

[0058] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0059] During the drying process of the clothes to be dried by the drying component controlled by the constant temperature signal, the control motor drives the drum component to rotate according to the operating parameters of the first drying condition, and controls the drying component to raise the temperature value of the drum component to the first drying temperature range corresponding to the first drying condition, so as to dry the fabric of the clothes to be dried.

[0060] If the running time of the first drying condition reaches the standard time corresponding to the operating parameters, the control motor drives the drum assembly to rotate according to the operating parameters of the second drying condition, and controls the drying assembly to raise the temperature value of the drum assembly to the second drying temperature range corresponding to the second drying condition, so as to dry the filling of the clothes to be dried; wherein, the minimum value of the second drying temperature range is greater than the maximum value of the first drying temperature range.

[0061] The operating parameters for the first drying temperature range, the second drying temperature range, the first drying condition, and the second drying condition can all be flexibly adjusted as needed. These operating parameters control the rotation of the drum assembly and include, but are not limited to, runtime, rotation speed, and rotation-to-stop ratio. Additionally, the standard duration represents the time required for the garment processing equipment to process the garments to be dried under the corresponding operating condition.

[0062] It should be noted that when the garment processing equipment dries clothes, the types of clothes to be dried include those with fillings, such as down jackets and cotton-padded clothes. These types of clothes take longer to dry, and the fabric is exposed to high temperature and humidity, which reduces the strength of the fabric fibers, making the fabric more susceptible to damage during the tumbling drying process.

[0063] In the embodiments of this application, the fabric of the garment to be dried is dried through the first drying temperature range corresponding to the first drying condition, so that the fabric can be initially dried at a suitable drying temperature. As a result, the temperature resistance of the fabric increases with the degree of dryness of the fabric, and the fabric is less likely to be damaged during the tumbling drying process.

[0064] After the first drying condition is completed, the filling of the clothes to be dried is further dried in the second drying temperature range corresponding to the second drying condition, which is higher than the first drying temperature range, so as to shorten the drying time.

[0065] For example, in the first drying condition, the fabric of the garment is dried in a first drying zone of 50℃-60℃, and in the second drying condition, the filling of the garment is dried in a second drying zone of 65℃-75℃. Correspondingly, in the first drying condition, to obtain better fabric drying results, the corresponding operating parameters, including the running time, rotation speed, and rotation-to-stop ratio, can be set to a duration of 20 minutes, a rotation speed of 45 rpm / s to 55 rpm / s, and a rotation-to-stop ratio of 20 / 5 (i.e., 20 seconds of rotation time and 5 seconds of stop time). In the second drying condition, to obtain better filling drying results, the corresponding operating parameters, including the running time, rotation speed, and rotation-to-stop ratio, can be set to a duration of 60 minutes, a rotation speed of 50 rpm / s to 60 rpm / s, and a rotation-to-stop ratio of 25 / 5 (i.e., 20 seconds of rotation time and 5 seconds of stop time).

[0066] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0067] Obtain the weight of the clothes to be dried inside the drum assembly;

[0068] If the weight value is greater than the preset overweight value, the standard duration corresponding to the operating parameters of the first drying condition and the second drying condition will be set as the overweight duration, wherein the overweight duration is greater than the standard duration.

[0069] If the weight value is less than the preset ultra-light value, the standard duration corresponding to the operating parameters of the first drying condition and the second drying condition will be set as the ultra-light duration, wherein the ultra-light duration is less than the standard duration.

[0070] Considering that the heavier the clothes to be dried, the higher their moisture content, making it more difficult for the clothes processing equipment to dry them, the embodiments of this application first obtain the weight of the clothes to be dried in the drum assembly, and then adjust the running time of the first and second drying conditions according to the weight value. This results in better drying effect of the clothes processing equipment and improves user satisfaction with the equipment.

[0071] The method for obtaining the weight of the clothes to be dried inside the drum assembly can be flexibly set as needed. In one example, a weighing sensor can be set in the clothes processing equipment to collect the weight of the clothes to be dried, thereby achieving the purpose of obtaining the weight of the clothes to be dried through the weighing sensor.

[0072] In another example, during the process of obtaining the weight of the clothes to be dried in the drum assembly, the motor drives the drum assembly to reach a first speed; the amplitude of the change in back electromotive force and the decay rate of the oscillation frequency are obtained when the speed of the drum assembly decreases from the first speed to 0; the weight of the clothes to be dried in the drum assembly is determined based on the amplitude of the change in back electromotive force and the decay rate of the oscillation frequency, so as to achieve the purpose of obtaining the weight of the clothes to be dried in the drum assembly.

[0073] Because the weight of the clothes to be dried varies, the corresponding centripetal force also varies. This means that the speed and attenuation of the rotation speed of the drum assembly driven by the clothes will also differ. Therefore, based on the connection between the drum assembly and the motor, feedback on the rotation of the drum assembly driven by the clothes can be obtained through the motor, specifically the amplitude of the change in the motor's back electromotive force and the rate of decay of the oscillation frequency. The weight value of the clothes to be dried can then be calculated using the amplitude of the back electromotive force change and the rate of decay of the oscillation frequency. This method is less susceptible to signal interference and provides a more accurate weight value. The first rotational speed can be flexibly set by the manufacturer according to the hardware of the clothing processing equipment and is not limited here.

[0074] In addition, when clothes are being dried in a garment processing device, they are usually dehydrated to initially reduce their moisture content. That is, the dehydration speed also affects the moisture content of the clothes. Therefore, in the embodiments of this application, the controller can also adjust the running time of the first and second drying conditions by adjusting the dehydration speed, i.e., by performing the following steps: obtaining the dehydration speed when dehydrating the clothes; if the dehydration speed is greater than the preset high dehydration speed, then setting the standard time corresponding to the operating parameters of the first and second drying conditions to a high-speed time, wherein the high-speed time is less than the standard time; if the dehydration speed is less than the preset low dehydration speed, then setting the standard time corresponding to the operating parameters of the first and second drying conditions to a low-speed time, wherein the low-speed time is greater than the standard time; that is, the faster the dehydration speed, the lower the moisture content of the clothes, and correspondingly, the shorter the drying time.

[0075] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0076] During the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the first drying condition, the operating parameters corresponding to the first drying condition are adjusted according to the weight value. The operating parameters include, but are not limited to, speed parameters and rotation-to-stop ratio parameters.

[0077] During the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the second drying condition, the operating parameters corresponding to the second drying condition are adjusted according to the weight value.

[0078] In the embodiments of this application, after obtaining the weight value of the clothes to be dried in the drum assembly, the operating parameters corresponding to the first drying condition and the second drying condition can be adjusted according to the weight value. This controls the motor to drive the drum assembly to rotate according to the adjusted operating parameters in the first and second drying conditions, respectively. As a result, the working process of the first and second drying conditions can be adjusted according to the actual weight value of the clothes to be dried, that is, it can be adjusted according to the moisture content of the clothes to be dried, thereby improving the drying effect of the clothes processing equipment and further enhancing user satisfaction.

[0079] Referring to the above example, the operating parameters for the first drying condition include a running time of 20 minutes, a rotation speed of 45 rpm / s to 55 rpm / s, and a rotation-to-stop ratio of 20 / 5 (i.e., a rotation time of 20 seconds and a stop time of 5 seconds); and the operating parameters for the second drying condition include a running time of 60 minutes, a rotation speed of 50 rpm / s to 60 rpm / s, and a rotation-to-stop ratio of 25 / 5 (i.e., a rotation time of 20 seconds and a stop time of 5 seconds). If the weight of the clothes to be dried inside the drum assembly 12 is greater than the preset overweight value, the operating parameters for the first drying condition, including the rotation speed and rotation-to-stop ratio, are adjusted to a rotation speed of 50 rpm / s to 60 rpm / s and a rotation-to-stop ratio of 25 / 5, respectively. The operating parameters for the second drying condition are adjusted to a rotation speed of 55 rpm / s to 75 rpm / s and a rotation-to-stop ratio of 30 / 5, in order to achieve a better drying effect when the clothes to be dried are heavier, i.e., when the moisture content of the clothes to be dried is higher.

[0080] Correspondingly, if the weight of the clothes to be dried in the drum assembly is less than the preset ultralight value, the operating parameters for the first drying condition, including the rotation speed and rotation-to-stop ratio, are adjusted to a rotation speed of 40 rpm / s to 50 rpm / s and a rotation-to-stop ratio of 15 / 5, respectively; the operating parameters for the second drying condition are adjusted to a rotation speed of 45 rpm / s to 55 rpm / s and a rotation-to-stop ratio of 20 / 5, achieving a better drying effect when drying lighter clothes.

[0081] Furthermore, as mentioned above, the spin speed also affects the moisture content of the clothes to be dried. Therefore, in another example, the controller is also configured to perform the following steps:

[0082] During the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the first drying condition, the operating parameters corresponding to the first drying condition are adjusted according to the dehydration speed. The operating parameters include, but are not limited to, speed parameters and rotation-to-stop ratio parameters. During the process of controlling the motor to drive the drum assembly to rotate according to the operating parameters of the second drying condition, the operating parameters corresponding to the second drying condition are adjusted according to the dehydration speed.

[0083] The specific process of adjusting the operating parameters of the first and second drying conditions according to the dehydration speed can refer to the above process of adjusting according to the weight value, and the principle is the same as the above adjustment process, so it will not be repeated here.

[0084] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0085] During the preheating process controlled by the drying component in response to the drying signal, the control motor drives the drum assembly to rotate according to the operating parameters of the shaking condition.

[0086] In the embodiments of this application, after obtaining the drying signal, during the process of controlling the drying component to perform preheating in response to the drying signal, the motor can be controlled to drive the drum assembly to rotate according to the operating parameters of the shaking condition, so as to disperse the clothes to be dried in the drum assembly. This makes it easier for the clothes to be dried to be dried to have a larger contact area with the heated air after shaking, thereby making the drying effect better and shortening the overall drying time.

[0087] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0088] After the clothes to be dried are dried by the drying component controlled by the constant temperature signal, the control motor drives the drum component to rotate according to the operating parameters of the cooling condition, and controls the fan and heating tube to stop running.

[0089] After the clothes are dried, the surface temperature of the clothes and the drum assembly is high. If a user handles the dried clothes at this time, they may be burned, posing a safety hazard. Therefore, in the embodiments of this application, after the drying assembly controls the clothes to be dried based on the constant temperature signal, indicating that the clothes are dried, the motor is controlled to drive the drum assembly to rotate according to the operating parameters of the cooling condition, and the fan and heating tube are controlled to stop running, so as to reduce the temperature of the surface of the drum assembly and the dried clothes inside the drum assembly, thereby avoiding burns when the user handles the dried clothes and reducing the safety hazards when using the clothes processing equipment.

[0090] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0091] Obtain the weight of the clothes to be dried inside the drum assembly;

[0092] Adjust the speed parameters and / or speed-to-stop ratio parameters for cooling conditions according to the weight value.

[0093] In the above process, when the clothing processing equipment is in cooling mode, it can first obtain the weight value of the clothes to be dried in the drum assembly, and then adjust the speed parameters and / or the rotation-to-stop ratio parameters of the cooling mode according to the weight value. This allows the motor to adjust the speed and amplitude of the drum assembly rotation according to the weight value when driving the drum assembly to rotate, thereby increasing the cooling area of ​​the clothes to be dried during the tumbling and cooling process driven by the drum assembly, thus shortening the cooling time.

[0094] Furthermore, considering that the weight of the clothes to be dried varies, their corresponding volumes also differ. If the weight of the clothes is too high, the corresponding volume is larger, and after the cooling process ends, some of the clothing surface may not have cooled sufficiently due to being wrapped by other clothes, causing its surface temperature to remain high and potentially resulting in burns when the user handles it. Conversely, if the weight of the clothes is too low, the corresponding volume is smaller, and the dried clothes will already be within a safe temperature range before the cooling process ends, meaning the user is less likely to get burned when handling the clothes, thus wasting resources. Therefore, in the embodiments of this application, the controller can also adjust the duration of the cooling process based on the weight value.

[0095] In another exemplary embodiment, the controller is also configured to perform the following steps:

[0096] During the process of controlling the motor to drive the cylinder assembly to rotate according to the operating parameters of the cooling condition, the temperature value inside the cylinder assembly is obtained;

[0097] If the temperature reaches the preset cooling temperature, the motor will stop running.

[0098] In the embodiments of this application, in order to further ensure that the temperature of the drum assembly surface and the temperature of the dried clothes surface are not likely to cause burns to the user, the temperature value inside the drum assembly can be obtained during the cooling process. The temperature value can be used to determine whether the surface of the drum assembly and the surface of the dried clothes have cooled down to a safe temperature range. That is, if the temperature value reaches the preset cooling temperature, the motor is controlled to stop running, thereby further reducing the probability of the user being burned.

[0099] In addition, after the temperature reaches the preset cooling temperature, the door lock of the clothing processing equipment can be automatically opened and the power can be cut off, thereby making it convenient for users to take out the dried clothes while reducing power consumption during standby.

[0100] Figure 2 is a flowchart illustrating the control process of the controller of the garment processing device in an exemplary embodiment of this application. As shown in Figure 2, the specific implementation method includes at least steps S210 to S270, which are described in detail below:

[0101] In step S210, a drying signal is acquired to indicate that the clothes to be dried are to be dried.

[0102] The specific method for obtaining the drying signal has been described in detail in the above process and will not be repeated here.

[0103] In step S220, in response to the drying signal, the control motor drives the drum assembly to rotate according to the operating parameters of the shaking condition.

[0104] In order to prevent clothes from clumping together during the drying process, the surface area of ​​the clothes after shaking is increased to allow for greater contact with the heated air, thereby shortening the drying time and improving the drying effect achieved by the clothing processing equipment.

[0105] In step S230, the drying component is controlled to operate in preheating mode.

[0106] By using the preheating mode, the air temperature inside the drum assembly is initially increased before the drying components begin drying the clothes, thereby further shortening the drying time. Furthermore, steps S220 and S230 can be run simultaneously; that is, while the drying components are operating in the preheating mode, the motor drives the drum assembly to rotate according to the operating parameters of the shaking mode.

[0107] In step S240, it is determined whether the number of times the preheating condition has been run has reached the preset number.

[0108] If the result is yes, then step S250 is executed to generate a constant temperature signal, which indicates that the air temperature in each area of ​​the cylinder assembly has reached the required preheating temperature after multiple preheating cycles and tends to stabilize. If the result is no, then step S230 is executed again to ensure that the air temperature in each area of ​​the cylinder assembly reaches the required preheating temperature.

[0109] In step S260, the drying component is controlled to dry the clothes to be dried based on the constant temperature signal.

[0110] After the constant temperature signal confirms that the air temperature inside the drum assembly has stabilized at the temperature corresponding to the preheating condition, the drying assembly is then controlled to dry the clothes. On the one hand, this shortens the time it takes for the drying assembly to raise the air temperature inside the drum assembly to the required drying temperature. On the other hand, once the air temperature inside the drum assembly has stabilized, it is easier to improve the accuracy of the temperature sensor in detecting the temperature rise inside the drum assembly. This avoids the temperature detected by the temperature sensor not keeping up with the actual temperature change inside the drum assembly during the subsequent drying process, which could lead to overheating of the heating element and cause it to trip and stop.

[0111] In addition, the specific implementation method for drying clothes based on the constant temperature signal control of the drying component can refer to the operation process of the first drying condition and the second drying condition described above.

[0112] In step S270, the control motor drives the cylinder assembly to rotate according to the operating parameters of the cooling condition, and controls the fan and heating tube to stop running.

[0113] To prevent users from being burned by the high temperature on the surface of the clothes or the drum assembly when taking out the dried clothes, a cooling mode is used to reduce the temperature of the surface of the drum assembly and the dried clothes inside the drum assembly, thereby reducing the safety hazards when users use the clothes processing equipment.
