This method has a certain time delay and often causes clothes to be over-dried or under-dried. This not only wastes electricity but also damages clothes and brings a poor user experience. In addition, this method increases the hardware cost of washing machines and the maintenance cost for users. Summary of the Invention

[0004] In order to achieve the above-mentioned objectives and other advantages of the present invention, a first objective of the present invention is to provide a drying control method for a garment processing apparatus, comprising the following steps: The water level of the garment processing device is monitored in real time to determine when to stop drying.

[0010] Furthermore, after the step of determining the initial weight of the clothing, the method further includes: Determine the initial time difference of multiple preset electrical angle intervals within the washing drum.

[0011] Furthermore, after the step of determining the weight of the clothes after drying, the method further includes: Determine the drying time difference for multiple preset electrical angle intervals within the washing drum.

[0013] Furthermore, the electrical angle interval is configured as multiple equally divided intervals of the mechanical angle of the washing drum.

[0014] Furthermore, the process of determining the initial time difference also includes the following steps: When driving the motor to rotate within the resonance range of the clothing processing device, the drain pump is turned off; The water level of the garment processing device is monitored in real time to determine the dryness or wetness of the garments.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0028] The drawing numbers in this application are only used to distinguish the steps in the scheme and are not used to limit the execution order of the steps. The specific execution order is as described in the specification.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] To address the issue that in related technologies, the clothes drying degree judgment algorithm used in washing machines is based on changes in temperature or humidity curves, requiring the use of temperature or humidity sensor detection values ​​to determine the clothes drying degree, this method has a certain time delay, often resulting in over-drying or under-drying of clothes. This not only wastes energy but also damages the clothes, leading to a poor user experience. In addition, this method increases the hardware cost of the washing machine and the maintenance cost for users. Embodiment 1 of the present invention provides a drying control method for a clothes processing device.

[0031] The clothing processing equipment can be configured as a washing machine, a washer-dryer combo, etc. For ease of description, this invention uses a drum washing machine as an example for illustration, and should not be construed as a limitation on the type of clothing processing equipment.

[0032] This method can be executed by the main control unit of the garment processing device. The main control unit can be implemented in the form of software and / or hardware, and is generally integrated into any electronic device with network communication capabilities, such as a mobile terminal, PC, or server.

[0033] Example 1 A drying control method for a garment handling device, such as Figure 1 As shown, it includes the following steps: S1. Monitor the water level of the garment processing device in real time to determine when to stop drying; Generally, the main drying technologies used in garment processing devices include condenser and heat pump types. Among them, the principle of condenser drying is similar to a fan combined with heating wires. First, the air is heated, and then the high-temperature air is used to heat the clothes and carry away the moisture. The moisture is then condensed into water and discharged.

[0034] The condenser-type garment care device has a condenser inside, which cools the hot and humid air, causing the water vapor to liquefy and be discharged through the drain pipe.

[0035] The heat pump type clothing dryer has an internal compressor that heats the air through a heat pump system. The hot air is then used to dry the clothes, causing the moisture in the clothes to evaporate into water vapor. The hot air carrying the water vapor then enters the condenser, where the condensed water is discharged outside the machine. At the same time, the hot air is also used to heat air again, starting the next cycle.

[0036] Taking a front-loading washing machine as an example, front-loading washing machines typically adopt an integrated design, with the water level sensor usually located at the bottom of the machine. The water level sensor determines the water level status of the washing machine by sensing the water level at the bottom.

[0037] In particular, for mini washing machines with smaller capacity, the water level changes are more noticeable, and their water level sensors are usually more sensitive and can more accurately sense the water level inside the washing machine. They are usually placed below or on the side of the inner drum of the washing machine.

[0038] During the clothes drying process, the clothes handling device collects water level information in real time through water level sensors installed within the device. The main control board of the device monitors the frequency of water level changes in real time to determine whether to stop drying. In some embodiments, such as Figure 2 As shown, the step of real-time monitoring of the water level in the garment processing device to determine when to stop drying includes: S11. Determine whether the water level frequency remains at an empty water level within a continuous preset time interval; S12. Determine whether to stop drying based on the judgment result.

[0039] Specifically, drying is stopped when the water level frequency remains at an empty water level for a continuous preset time interval; for example, drying is stopped when the main control board monitors that the water level frequency remains at an empty water level for 10 consecutive minutes.

[0040] When the water level frequency does not remain at an empty water level within a continuous preset time interval, the water level sensor continuously collects the water level information of the clothing processing device in real time, and monitors the changes in the water level frequency of the clothing processing device in real time to determine whether to stop drying.

[0041] S2. Obtain the parameters after the clothes are dried and the initial parameters; In some embodiments, the parameters after drying include the weight of the clothes after drying, and the initial parameters of the clothes include the initial weight of the clothes.

[0042] To obtain the initial weight of the clothing, in some embodiments, prior to the step of real-time monitoring of the water level in the clothing processing device, the method further includes: Determine the initial weight of the clothing.

[0043] In some embodiments, such as Figure 3 As shown, the steps for determining the initial weight of clothing include: S100: Control the motor of the clothing processing device to rotate and maintain it at a preset speed; The user places clothes into the washing tub of the garment processing unit, presses the start button, and the unit begins operation. The main control board then controls the motor to rotate and maintain it at a stable, preset speed. It should be noted that the motor is operating at a low speed, at least below the normal spin-drying speed. For example, given that the normal spin-drying speed is generally between 600-1400 rpm, the motor speed can be configured to 100-200 rpm, or even lower, 30-60 rpm. This is merely an example and should not be interpreted as a limitation on the motor speed.

[0044] Preferably, the motor controlling the clothing handling device to rotate and maintain at a preset speed is configured to drive the motor using a drive signal with a fixed duty cycle. Here, duty cycle refers to the proportion of energized time relative to the total time within a pulse cycle. Duty cycle control is also commonly known as pulse width modulation (PWM) technology. It modulates the pulse width of a voltage signal of a certain frequency applied to the working actuator through an electronic control unit, i.e., duty cycle control, to achieve precise and continuous control of the actuator's operating status. Therefore, this embodiment utilizes a PWM control signal with a fixed duty cycle to drive the motor with constant current, enabling high-performance control of the motor.

[0045] S110. Determine the rotational speed of the washing drum of the clothing processing device; Specifically, the step of determining the rotation speed of the washing drum of the garment processing device includes: S111. Obtain the acceleration data of the washing drum; Acceleration data can be obtained through inertial measurement units (IMUs), which can be IMUs (Inertial Measurement Units) or accelerometers. Depending on the measurement dimension, accelerometers are classified into single-axis, bi-axis, and tri-axis types. Compared to single-axis and bi-axis accelerometers, which can only detect changes in motion in a plane, tri-axis accelerometers can measure acceleration in three-dimensional space with a single product, thus meeting the needs of miniaturization and applications in more fields.

[0046] Because accelerometers can measure acceleration caused by motion, that is, acceleration caused by gravity (1g), they are suitable for calculating tilt angles. The operating state of the washing drum is based on the rotational position of the drum, and accelerometers can quickly detect changes in the movement of the washing drum without relying on external signal sources, providing accurate motion information independently in a short time.

[0047] For ease of description, this embodiment uses a triaxial accelerometer as an example of the inertial measurement device, and should not be construed as a limitation on the type of inertial measurement device. A triaxial accelerometer is used to measure the acceleration of the washing tub and connected components (e.g., tripod, lifting ribs) in three orthogonal directions (typically the x-axis, y-axis, and z-axis).

[0048] Inertial measurement units (IMUs) can be placed at the location to be monitored, depending on actual monitoring needs, including but not limited to the washing drum body, tripod, lifting ribs, and other locations requiring monitoring. Considering other applications of the data collected by the IMU in garment handling equipment, such as… Figure 9 As shown, the inertial measurement device is preferably installed inside the lifting rib 2 of the washing drum 1.

[0049] S112. Calculate the rotational speed of the washing drum using the acceleration data.

[0050] Optionally, the angle can be calculated based on measurements from a triaxial accelerometer. Specifically, the spring compression is determined by the angle between the accelerometer and the ground, and the specific force can be measured by the spring compression length. Therefore, in the absence of external force, the triaxial accelerometer can accurately measure the tilt angle. Then, the position of the washing drum and connected components (e.g., tripod, lifting ribs) relative to their initial positions can be obtained from this tilt angle. By analyzing the position of the washing drum at different times, the rotational speed of the washing drum can be determined.

[0051] S120. Calculate the weight of the clothes based on the rotation speed of the washing drum; When the motor is driven by a PWM control signal with a fixed duty cycle, the rotational speed of the washing drum will vary depending on the weight of the clothes inside. The rotational speed of the washing drum can be obtained by measuring the acceleration data using an inertial measurement device, thereby calculating the weight of the clothes, which is then stored in non-volatile storage.

[0052] In other embodiments, such as Figure 4 As shown, the steps for determining the initial weight of clothing include: S100: Control the motor of the clothing processing device to rotate and maintain it at a preset speed; The user places clothes into the washing tub of the garment processing unit, presses the start button, and the garment processing unit begins operation. The main control board then controls the motor to rotate and maintain it at a stable preset speed. It should be noted that the motor is at a low speed at this time, at least lower than the normal spin-drying speed.

[0053] Preferably, the motor controlling the clothing handling device to rotate and maintain at a preset speed is configured to drive the motor using a PWM control signal with a fixed duty cycle. Utilizing a PWM control signal with a fixed duty cycle to drive the motor with constant current achieves high-performance control of the motor.

[0054] S130. Collect the bus current of the motor and determine the weight of the clothes based on the bus current. The motor bus current and the weight of the clothes in the washing drum can be pre-calibrated and stored in the main control board for easy determination of the clothes weight based on the motor bus current.

[0055] The water level in the laundry treatment unit can be detected and the initial water level determined before the user puts clothes into the washing drum. In some embodiments, before the step of determining the initial weight of the clothes, the following steps are also included: The presence of water in the garment processing device is determined by monitoring the water level within the device. Optionally, when the clothing processing device is in standby mode, the value of the water level sensor can be collected in real time to determine whether the clothing processing device is in a waterless state. If the water level of the clothing processing device is higher than the preset water level, it is determined that there is water in the device; otherwise, it is determined that there is no water in the device.

[0056] The decision on whether to perform a drainage action is based on the judgment result; specifically, if it is determined that there is water in the device, the drainage pump is turned on to drain the water.

[0057] Record the initial water level in the clothing processing device when it is dry. Subsequent water level changes can be determined based on this initial water level, or based on data from before and after water level monitoring.

[0058] To obtain the weight of the clothes after drying. In some embodiments, before obtaining the parameters of the clothes after drying, the method further includes: Determine the weight of the clothes after drying.

[0059] In some embodiments, the step of determining the weight of the clothes after drying includes: S100: Control the motor of the clothing processing device to rotate and maintain it at a preset speed; After drying stops, the main control board controls the motor to rotate and maintains it at a stable preset speed. It should be noted that the motor is at a low speed at this time, at least lower than the normal dehydration speed.

[0060] Preferably, the motor controlling the clothing handling device to rotate and maintain at a preset speed is configured to drive the motor using a PWM control signal with a fixed duty cycle. Utilizing a PWM control signal with a fixed duty cycle to drive the motor with constant current achieves high-performance control of the motor.

[0061] S110. Determine the rotational speed of the washing drum of the clothing processing device; Specifically, such as Figure 5 As shown, the step of determining the rotational speed of the washing drum of the garment processing device includes: S111. Obtain the acceleration data of the washing drum; Acceleration data can be obtained through inertial measurement units (IMUs), which can be IMUs (Inertial Measurement Units) or accelerometers. Depending on the measurement dimension, accelerometers are classified into single-axis, bi-axis, and tri-axis types. Compared to single-axis and bi-axis accelerometers, which can only detect changes in motion in a plane, tri-axis accelerometers can measure acceleration in three-dimensional space with a single product, thus meeting the needs of miniaturization and applications in more fields.

[0062] Because accelerometers can measure acceleration caused by motion, that is, acceleration caused by gravity (1g), they are suitable for calculating tilt angles. The operating state of the washing drum is based on the rotational position of the drum, and accelerometers can quickly detect changes in the movement of the washing drum without relying on external signal sources, providing accurate motion information independently in a short time.

[0063] For ease of description, this embodiment uses a triaxial accelerometer as an example of the inertial measurement device, and should not be construed as a limitation on the type of inertial measurement device. A triaxial accelerometer is used to measure the acceleration of the washing tub and connected components (e.g., tripod, lifting ribs) in three orthogonal directions (typically the x-axis, y-axis, and z-axis).

[0064] S112. Calculate the rotational speed of the washing drum using the acceleration data.

[0065] Optionally, the angle can be calculated based on measurements from a triaxial accelerometer. Specifically, the spring compression is determined by the angle between the accelerometer and the ground, and the specific force can be measured by the spring compression length. Therefore, in the absence of external force, the triaxial accelerometer can accurately measure the tilt angle. Then, the position of the washing drum and connected components (e.g., tripod, lifting ribs) relative to their initial positions can be obtained from this tilt angle. By analyzing the position of the washing drum at different times, the rotational speed of the washing drum can be determined.

[0066] S120. Calculate the weight of the clothes based on the rotation speed of the washing drum; When the motor is driven by a PWM control signal with a fixed duty cycle, the rotational speed of the washing drum will vary depending on the weight of the clothes inside. The rotational speed of the washing drum can be obtained by measuring the acceleration data using an inertial measurement device, thereby calculating the weight of the clothes and ultimately their weight after drying.

[0067] In other embodiments, the step of determining the weight of the clothes after drying includes: S100: Control the motor of the clothing processing device to rotate and maintain it at a preset speed; After drying stops, the main control board controls the motor to rotate and maintains it at a stable preset speed. It should be noted that the motor is at a low speed at this time, at least lower than the normal dehydration speed.

[0068] Preferably, the motor controlling the clothing handling device to rotate and maintain at a preset speed is configured to drive the motor using a PWM control signal with a fixed duty cycle. Utilizing a PWM control signal with a fixed duty cycle to drive the motor with constant current achieves high-performance control of the motor.

[0069] S130. Collect the bus current of the motor and determine the weight of the clothes based on the bus current. The motor bus current and the weight of the clothes in the washing drum can be pre-calibrated and stored in the main control board for easy determination of the clothes weight based on the motor bus current.

[0070] S3. Determine whether to end the drying process by comparing the parameters after the clothes are dried with the initial parameters.

[0071] Specifically, the parameters after the clothes are dried are compared with the initial parameters. When the values ​​of both are within a preset reasonable range, the drying process ends. When the values ​​of both are not within a preset reasonable range, the above steps are repeated until it is determined that the drying process can end.

[0072] In some embodiments, the decision to end drying can be based solely on the weight of the clothes after drying and the initial weight provided in the above embodiments. That is, the weight of the clothes after drying is compared with the initial weight; if both values ​​are within a reasonable range, drying is ended; otherwise, the above steps are repeated until it is determined that drying can be ended. This embodiment determines the dryness of the clothes based on their weight, reducing the hardware cost of temperature and humidity sensors.

[0073] In other embodiments, the parameters after clothes drying also include the time difference after drying of multiple preset electrical angle intervals within the washing drum, and the initial parameters of the clothes include the initial time difference of multiple preset electrical angle intervals within the washing drum.

[0074] To obtain the initial time difference between multiple preset electrical angle intervals within the washing drum, in some embodiments, after the step of determining the initial weight of the clothes, the method further includes: Determine the initial time difference of multiple preset electrical angle intervals within the washing drum.

[0075] In some embodiments, such as Figure 6 As shown, the step of determining the initial time difference of multiple preset electrical angle intervals within the washing drum includes: S200, drive the motor to rotate within the resonance range of the clothing processing device, and maintain a constant rotation speed; The resonance range of the clothing processing device is the range of rotational speeds in which the clothing processing device vibrates the most. It can be set according to the experimental conditions. By detecting the rotational speed of the motor, it can be determined whether the rotational speed of the motor is within the resonance range.

[0076] S210. Obtain multiple preset electrical angle ranges within the washing drum; Preferably, the electrical angle interval is configured as multiple equally divided intervals of the mechanical angle of the washing drum.

[0077] Optionally, such as Figure 9 As shown, since the mechanical angle of the washing drum 1 rotating one revolution is 360 degrees, the mechanical angle is divided into 24 electrical angle intervals. 360 degrees / 24 = 15 degrees, that is, each electrical angle interval is 15 degrees.

[0078] S220. Calculate the time difference of the multiple electrical angle intervals using the acceleration data corresponding to each of the multiple electrical angle intervals.

[0079] Because of the different weights of the clothing, the time it takes to complete one electrical angle interval when rotating at the resonant interval speed varies. An inertial measurement device can be used to measure the acceleration data of each electrical angle interval to calculate the time difference of the 24 electrical angle intervals, and this value can be used to determine the weight of the clothing.

[0080] In conjunction with the above embodiments, the acceleration data measured by the triaxial accelerometer can be used to calculate the relative initial position of the washing drum and connected components (e.g., tripod, lifting ribs). Based on this, the time to complete each electrical angle interval can be calculated, thereby obtaining the time difference to complete each electrical angle interval, and thus obtaining the initial time difference of multiple electrical angle intervals, which is stored in non-volatile storage space.

[0081] To obtain the time difference after drying for multiple preset electrical angle intervals within the washing drum, in some embodiments, after the step of determining the weight of the clothes after drying, the method further includes: Determine the drying time difference for multiple preset electrical angle intervals within the washing drum.

[0082] In some embodiments, the step of determining the post-drying time difference among a plurality of preset electrical angle intervals within the washing drum includes: S200, drive the motor to rotate within the resonance range of the clothing processing device, and maintain a constant rotation speed; The resonance range of the clothing processing device is the range of rotational speeds in which the clothing processing device vibrates the most. It can be set according to the experimental conditions. By detecting the rotational speed of the motor, it can be determined whether the rotational speed of the motor is within the resonance range.

[0083] S210. Obtain multiple preset electrical angle ranges within the washing drum; Preferably, the electrical angle interval is configured as multiple equally divided intervals of the mechanical angle of the washing drum.

[0084] Optionally, such as Figure 9 As shown, since the mechanical angle of the washing drum 1 rotating one revolution is 360 degrees, the mechanical angle is divided into 24 electrical angle intervals. 360 degrees / 24 = 15 degrees, that is, each electrical angle interval is 15 degrees.

[0085] S220. Calculate the time difference of the multiple electrical angle intervals using the acceleration data corresponding to each of the multiple electrical angle intervals.

[0086] Because the weight of clothes varies after drying, the time it takes to complete one electrical angle interval when rotating at the resonant interval speed differs. An inertial measurement device can be used to measure the acceleration data of each electrical angle interval to calculate the time difference of the 24 electrical angle intervals, and this value can be used to determine the weight of the clothes.

[0087] In conjunction with the above embodiments, the position of the washing drum and connected components (e.g., tripod, lifting ribs) relative to the initial position can be calculated by using acceleration data measured by a triaxial accelerometer. Based on this, the time to complete each electrical angle interval can be calculated, thereby obtaining the time difference to complete each electrical angle interval, and thus obtaining the drying time difference of multiple electrical angle intervals.

[0088] Considering the actual structural design of the garment handling device, especially for small-capacity mini washing machines, the water level changes during the drying process are more significant than the weight changes of the clothes in the drum. Therefore, the dryness type of the clothes can be determined based on this, and the parameters of the drying program can be intelligently adjusted, making the drying process of the garment handling device more intelligent and controllable. In some embodiments, such as... Figure 7 As shown, the process of determining the initial time difference also includes the following steps: S300. When driving the motor to rotate within the resonance range of the clothing processing device, turn off the drain pump; S310. Monitor the changes in the water level frequency of the clothing treatment device in real time to determine the dry or wet type of the clothing; For example, if the water level frequency of the clothing processing device changes by 0.2kHz three times consecutively, the clothing is determined to be a wet load; otherwise, the clothing is determined to be a dry load.

[0089] S320. When the garment is determined to be dry load, the drying parameters are determined based on the initial weight and / or the initial time difference.

[0090] Optionally, if the clothing is determined to be a dry load, the drying parameters, including the drying time required, the temperature settings for turning on and off the drying equipment, etc., are determined by querying the drying parameter table in the program based on the initial weight of the clothing and / or the initial time difference of the multiple electrical angle intervals determined in the above embodiments.

[0091] Then, the control motor stops rotating, and after the main control board controls the clothing processing device to complete the washing, rinsing, and dehydration processes, it enters the drying process. During the drying process, the drying parameters determined in the above embodiments can be called to control the drying of the clothes.

[0092] In conjunction with the above embodiments, the steps of obtaining the parameters after drying the clothes and the initial parameters include: The weight of the clothes after drying, the initial weight, and the time difference after drying and the initial time difference of multiple electrical angle intervals are obtained.

[0093] S3. Determine whether to end the drying process by comparing the parameters after the clothes are dried with the initial parameters.

[0094] In conjunction with the above embodiments, after determining to stop drying, in some embodiments, such as Figure 8As shown, the step of determining whether to end the drying process by comparing the parameters after drying with the initial parameters includes: S31. The weight of the clothes after drying and the time difference after drying in the multiple electrical angle intervals are compared with the initial weight and the initial time difference, respectively. S32. If the difference between the weight of the clothes after drying and the initial weight, and the difference between the time difference after drying and the initial time difference in the multiple electrical angle intervals are all within the corresponding preset range, then the drying process ends. S33. If the weight of the clothes after drying differs from the initial weight, or if the difference between the drying time difference and the initial time difference in the multiple electrical angle intervals is not within the corresponding preset range, then return to S1. Monitor the water level of the clothes processing device in real time to determine when to stop drying and continue execution. For example, it can be checked every 10 minutes until the conditions are met, at which point drying is considered to end.

[0095] Traditional drying algorithms use temperature or humidity change curves to determine the dryness of clothes, which has a certain degree of lag. This embodiment determines the dryness of clothes based on the weight of the clothes and the time difference between multiple electrical angle intervals, resulting in better real-time performance.

[0096] It should be noted that the drying control method of the clothing handling device provided in this embodiment is not only applicable to mini washing machines, but also to large-capacity washing machines. It can be used alone or in conjunction with traditional temperature and humidity sensors to achieve redundant protection of dual-algorithm operation for drying, reduce user maintenance costs, and improve user experience.

[0097] This embodiment provides a drying control method for a clothing processing device. The method includes the following steps: real-time monitoring of the water level in the clothing processing device to determine when to stop drying; acquiring post-drying parameters and initial parameters; and determining whether to end drying based on the post-drying parameters and the initial parameters. This embodiment can quickly and in real-time determine the degree of dryness of the clothing based on the post-drying parameters, making the drying effect of the clothing processing device intelligently controllable. This avoids over-drying or under-drying of clothing, reducing energy consumption and preventing damage to clothing, thus improving the user experience. Furthermore, it eliminates the need for additional temperature and humidity sensors, reducing the hardware cost of the washing machine and the user's maintenance costs.

[0098] Example 2 A garment processing apparatus is provided, employing the method described above. A detailed description of the method can be found in the corresponding descriptions of the above method embodiments, and will not be repeated here. In some embodiments, the garment processing apparatus may be used as a washing machine, and in other embodiments, as a washer-dryer combo.

[0099] The garment processing device includes a washing drum, a water level sensor, an inertial measurement unit, and a main control board. The inertial measurement unit is installed inside the washing drum and is used to measure the acceleration data of the washing drum. The water level sensor is used to monitor the water level information inside the device. The main control board is used to determine whether to end the drying process based on the acceleration data and the water level information.

[0100] Generally, the main drying technologies used in garment processing devices include condenser and heat pump types. Among them, the principle of condenser drying is similar to a fan combined with heating wires. First, the air is heated, and then the high-temperature air is used to heat the clothes and carry away the moisture. The moisture is then condensed into water and discharged.

[0101] The condenser-type garment care device has a condenser inside, which cools the hot and humid air, causing the water vapor to liquefy and be discharged through the drain pipe.

[0102] The heat pump type clothing dryer has an internal compressor that heats the air through a heat pump system. The hot air is then used to dry the clothes, causing the moisture in the clothes to evaporate into water vapor. The hot air carrying the water vapor then enters the condenser, where the condensed water is discharged outside the machine. At the same time, the hot air is also used to heat air again, starting the next cycle.

[0103] Taking a front-loading washing machine as an example, front-loading washing machines typically adopt an integrated design, with the water level sensor usually located at the bottom of the machine. The water level sensor determines the water level status of the washing machine by sensing the water level at the bottom.

[0104] In particular, for mini washing machines with smaller capacity, the water level changes are more noticeable, and their water level sensors are usually more sensitive and can more accurately sense the water level inside the washing machine. They are usually placed below or on the side of the inner drum of the washing machine.

[0105] In some embodiments, the garment handling device further includes a washing drum power supply module. A wiring space is formed inside the fixing device of the washing drum. Wires pass through the wiring space and exit from the end of the fixing device. The main control board supplies power to the inertial measurement unit and communicates with it through the washing drum power supply module and the wires inside the fixing device of the washing drum.

[0106] Inertial measurement units (IMUs) can be placed at the location to be monitored, depending on actual monitoring needs, including but not limited to the washing drum body, tripod, lifting ribs, and other locations requiring monitoring. Considering other applications of the data collected by the IMU in garment handling equipment, such as… Figure 9 As shown, the inertial measurement device is preferably installed inside the lifting rib 2 of the washing drum 1.

[0107] It should be noted that the specific implementation of the washing drum power supply scheme of the inertial measurement device described in this embodiment is not limited to the structure in the above embodiment. All schemes that can achieve washing drum power supply belong to the schemes of this application. For example, the invention described in the patent application number CN202211607494.0, entitled "A device for power supply inside the drum of a drum washing machine and a washing machine", and the invention described in the patent application number CN2023116816837, entitled "A device for power supply inside the drum of a drum washing machine and a washing machine", etc.
