[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0038] In existing garment processing equipment (such as dryers), filters tend to become clogged after a period of use. Current technologies for detecting filter clogging typically rely on fan power detection, temperature changes near the air outlet or filter, and / or specific detection devices to inspect the filter surface and determine clogging status. However, these methods inevitably add significant electrical equipment, increasing costs. Furthermore, they require protection against potentially high-temperature environments; otherwise, the reliability and lifespan of the detection device will be compromised. The complex data acquisition and processing algorithms also increase the computational demands on the garment processing equipment, often limiting its application scenarios. Fan power detection, on the other hand, is often affected by variations in fan performance, resulting in unreliable and frequently erroneous detection or identification results, causing inconvenience for users.

[0039] To address the aforementioned technical problems, embodiments of the present invention provide a control method for a garment processing device, wherein the garment processing device is in a drying mode, such as... Figure 1 As shown, the control method includes the following steps:

[0040] Step S101: Control the roller of the garment processing equipment to the first working state and determine the first working parameters;

[0041] Step S102: Control the roller to the second working state and determine the second working parameters;

[0042] Step S103: Determine the difference between the first working parameter and the second working parameter, and determine the filter clogging status of the clothing processing equipment based on the difference.

[0043] The clothing processing device in this embodiment can be a device with a drying function, such as a dryer, washer-dryer combo, or other devices with this function. Taking a dryer as an example, the dryer includes a housing, a drum, a fan, a filter, and a control device. The drum is rotatably disposed inside the housing, the fan is disposed on the back side of the housing, and the filter is disposed on the front side of the housing. An air duct connecting the fan and the filter is also formed inside the housing, and the air duct passes through the drum. The control device includes a processor 1, which is communicatively connected to the drum, the fan, and the reminder module. It can send different control commands to the above-mentioned components to make each component perform its respective function.

[0044] Furthermore, the dryer also includes a motor, which is housed in the casing and communicatively connected to the processor 1. The motor's drive output is connected to the drum to drive its rotation. After determining that the dryer is in drying mode, the processor 1 automatically executes the aforementioned control method to detect the dryer's filter clogging status. Specifically, the first operating state is the drum's forward rotation, and the second operating state is the drum's reverse rotation. The first operating parameter includes the motor load in the forward rotation state, and the second operating parameter includes the motor load in the reverse rotation state.

[0045] In one embodiment of the present invention, after the processor 1 determines that the dryer has started the drying mode, it first controls the drum and the impeller to rotate simultaneously in the forward direction (clockwise in this embodiment). During the rotation, the impeller can send external air into the dryer's housing. The air entering the housing passes through the air duct and then exits through the filter. When the air passes through the drum, it acts on the drum, so the drum will bear the wind load. That is, when the motor drives the drum to rotate in this working state, it must not only overcome the load brought by the rotation of the drum and its own load (i.e., the drum load), but also overcome the load of the wind applied to the drum (i.e., the wind load). At this time, the motor load is roughly equal to the sum of the drum load and the wind load. When the drum rotates in the reverse direction... When the direction (counterclockwise in this embodiment) is rotated, the rotation direction of the impeller changes. At this time, the impeller can no longer send external air into the dryer's housing, so no air acts on the drum, and the drum will not bear the wind load. In this working state, when the motor drives the drum to rotate, it only needs to overcome the load brought by the drum's own rotation (i.e., the drum load). That is, at this time, the motor load corresponds to the drum load. Therefore, the processor can detect the working parameters of the drum of the clothing processing equipment under different working states based on the above principle, and use the difference in working parameters under different working states to determine the filter clogging status of the clothing processing equipment. Among them, the motor load is the power consumed when the motor drives the drum to rotate.

[0046] In one embodiment of the present invention, the control device further includes a motor load detection device 2, which is mounted on the motor and communicatively connected to the processor 1. The motor load detection device 2 detects the motor load and sends the detected load value to the processor 1. When the motor rotates in the forward direction, the motor load detection device 2 detects a first operating parameter and sends it to the processor 1; when the motor rotates in the reverse direction, it detects a second operating parameter and sends it to the processor 1. After obtaining the first and second operating parameters, the processor 1 calculates the difference between them, which is the air load. The processor 1 then determines the filter clogging status based on the magnitude of the air load.

[0047] In one embodiment of the present invention, determining the first operating parameter includes:

[0048] Once it is determined that the drum is rotating in the forward direction, the first current value of the motor is obtained. The first current value represents the motor load in the forward rotation state.

[0049] In one embodiment of the present invention, determining the second operating parameter includes:

[0050] Once it is determined that the drum is in reverse, the second current value of the motor is obtained. The second current value represents the motor load in the reverse state.

[0051] Specifically, in one embodiment of the present invention, the motor load detection device 2 is a current detection sensor. When the drum is rotating in the forward direction, the first current value detected by the current detection sensor is the first operating parameter; when the drum is rotating in the reverse direction, the second current value detected by the current detection sensor is the second operating parameter. After detecting the two current values ​​respectively, the current detection sensor sends the two current values ​​to the processor 1. The processor 1 has pre-stored the resistance value of the motor, and then calculates the power according to the formula P = I. 2 The motor load can be calculated using R, where P is the motor load, I is the current value, and R is the resistance value.

[0052] In another embodiment of the present invention, the motor load detection device 2 is a voltage detection sensor. The voltage detection sensor can detect the voltage value of the motor when the roller is rolling. After the voltage detection sensor completes the detection, it sends the voltage value to the processor 1. The processor 1 has the resistance value of the motor pre-stored in its memory. After obtaining the voltage value detected by the voltage detection sensor, the processor 1 can calculate the power according to the formula P = U. 2 / R calculates the electrical load, where P is the electrical load, U is the voltage value, and R is the resistance value.

[0053] In another embodiment of the present invention, the motor load detection device 2 is an IPM (Intelligent Power Module), which can directly obtain the power value in the motor and send it to the processor 1.

[0054] Figure 3 This graph shows the changes in motor load and the degree of clogging in the garment handling equipment as the drum rotates in both forward and reverse directions. In this graph, the horizontal axis represents the degree of clogging in the garment handling equipment, and the vertical axis represents the motor load. Figure 3In the diagram, the first line 3 represents the relationship between the motor load and the degree of clogging in the garment processing equipment when the drum rotates forward. This line is a curve where the motor load gradually decreases, indicating that as the degree of clogging in the garment processing equipment increases during forward rotation, the motor load continuously changes and shows a gradually decreasing trend. The second line 4 represents the relationship between the motor load and the degree of clogging in the garment processing equipment when the drum rotates backward. This line is a straight line where the motor load remains constant, indicating that as the degree of clogging in the garment processing equipment increases during reverse rotation, the motor load does not change. Furthermore, under the same clogging condition, the motor load during forward rotation is greater than the motor load during reverse rotation, and the motor load difference D is the difference in motor load between forward and reverse rotation.

[0055] In one embodiment of the present invention, determining the filter clogging status of the garment processing device based on the difference includes:

[0056] Determine whether the difference is less than the first preset value;

[0057] If the difference is less than the first preset value, it is determined that the filter of the clothing processing equipment is clogged.

[0058] In one embodiment of the present invention, determining the filter clogging status of the clothing processing device based on the difference further includes:

[0059] Determine whether the difference is greater than the first preset value;

[0060] If the difference is greater than the first preset value, it is determined that the filter of the clothing processing equipment is not clogged.

[0061] The air load value differs depending on whether the filter is clogged or not, and also varies depending on the degree of clogging. When the filter is not clogged, the air entering the housing flows smoothly through the duct and exits more through the filter, resulting in less airflow acting on the drum and a relatively smaller air load on the drum. Conversely, when the filter is clogged, the air entering the housing cannot flow smoothly through the duct and exits less through the filter, resulting in more airflow acting on the drum and a relatively larger air load on the drum. Therefore, the drum experiences a greater air load when the filter is clogged compared to when the filter is not clogged.

[0062] Based on the above principle, processor 1 can further determine the clogging status of the dryer filter based on the difference between the first working parameter and the second working parameter. Specifically, processor 1 compares the obtained difference with a first preset value stored in processor 1. If the difference is less than the first preset value, it indicates that the dryer filter is clogged; if the difference is less than the first preset value, it indicates that the dryer filter is not clogged. Further, the first preset value can be determined based on multiple experiments or theoretical calculations. In this embodiment, the first preset value is preferably 80W. That is, when the difference between the first working parameter and the second working parameter is less than 80W, it can be determined that the dryer filter is clogged; when the difference between the first working parameter and the second working parameter is greater than or equal to 80W, it can be determined that the dryer filter is not clogged.

[0063] In one embodiment of the present invention, when the difference is less than a first preset value, determining that the filter of the clothing processing device is clogged further includes:

[0064] Determine whether the difference is less than a second preset value, wherein the second preset value is less than a first preset value;

[0065] If the difference is less than the second preset value, the filter of the clothing processing equipment is determined to be in a secondary clogging state; otherwise, the filter of the clothing processing equipment is determined to be in a primary clogging state.

[0066] The degree of congestion in the second-level congestion state is greater than that in the first-level congestion state.

[0067] After determining the filter clogging status of the dryer, processor 1 continues with subsequent judgment steps to further determine the degree of clogging. Specifically, if the difference is less than a first preset value, the more severe the clogging, the larger the difference. Therefore, to further determine the clogging status, processor 1 needs to determine if the difference is less than a second preset value. If the difference is less than the second preset value, the filter of the clothing processing device is determined to be in a level two clogging state; otherwise, the filter of the clothing processing device is determined to be in a level one clogging state (i.e., when the difference is greater than or equal to the second preset value but less than the first preset value, the filter of the clothing processing device is in a level one clogging state). In this embodiment, level two clogging is a severe clogging state, and level one clogging is a moderate clogging state. The second preset value can be determined based on multiple experiments or theoretical calculations. In this embodiment, the second preset value is preferably 40W.

[0068] In one embodiment of the present invention, the control method further includes:

[0069] If the filter of the garment processing equipment is found to be clogged, the user will be prompted to clean the filter.

[0070] The dryer also includes a reminder module that communicates with the processor 1. The reminder module can be a display screen or a voice player. The display screen can inform the user of the dryer filter's clogging status by displaying text and remind the user to clean the filter in time when it becomes clogged. The voice player can inform the user of the dryer filter's clogging status by broadcasting voice and remind the user to clean the filter in time when it becomes clogged.

[0071] Specifically, when processor 1 determines that the filter is not clogged, it does not need to issue a control command to the reminder module, and the reminder module does not issue a reminder message. If processor 1 determines that the filter is clogged, it controls the reminder module to send a reminder message to the user to clean the filter in a timely manner to avoid problems such as increased drying time, / or incomplete drying, and / or increased power consumption, thereby further improving the user experience. Furthermore, if processor 1 determines that the filter is in a first-level clogged state, it controls the reminder module to remind the user that the dryer's filter is in a first-level clogged state, reminding the user to clean the filter in a timely manner to prevent the dryer from being clogged for extended periods. The operation is beneficial for improving drying efficiency and reducing energy consumption. If the processor 1 determines that the filter is in a secondary clogging state, the processor 1 will not only control the reminder module to issue a corresponding reminder, that is, to inform the user that the dryer's filter is in a secondary clogging state, but also control the reminder module to increase the number of reminders (e.g., 5 times) and the intensity (e.g., increase the light effect or increase the prompt volume) to increase the user's attention to filter cleaning. The processor 1 will control the dryer to automatically turn on the filter clogging detection function again before the next drying program starts. If it is detected that the user still has not cleaned the filter (i.e., the filter is still in a secondary clogging state), the processor 1 will control the dryer to stop running until the filter is detected to be unclogging.

[0072] Another embodiment of the present invention provides a garment processing device, the garment processing device including a processor configured to execute the control method for the garment processing device described in the above embodiments.

[0073] The clothing processing device in this embodiment is preferably a clothes dryer. The clothes dryer includes a housing, a drum, a fan, a filter, and a reminder module. The drum is rotatably disposed inside the housing, the fan is disposed on the back side of the housing, and the filter is disposed on the front side of the housing. An air duct connecting the fan and the filter is also formed inside the housing, and the air duct passes through the drum. The device includes a processor 1, which is communicatively connected to the drum, the fan, and the reminder module. The processor 1 can send different control commands to the above-mentioned components to make each component perform its respective function. The reminder module is a display screen or a voice player. The display screen can inform the user of the clogging status of the dryer filter by displaying text and remind the user to clean the filter in time when it is clogged. The voice player can inform the user of the clogging status of the dryer filter by voice broadcast and remind the user to clean the filter in time when it is clogged.

[0074] In embodiments of the present invention, the garment processing device further includes:

[0075] The motor load detection device is configured to detect the motor load of the garment processing equipment.

[0076] Furthermore, the dryer also includes a motor, which is housed in the casing and communicatively connected to the processor 1. The drive output terminal of the motor is connected to the drum to drive the drum to rotate. The motor load is the power consumed when the motor drives the drum to rotate. In one embodiment of the invention, the motor load detection device 2 is a current detection sensor. The current detection sensor can detect the current value of the motor when the drum rotates. After detection, the current detection sensor sends the current value to the processor 1. The processor 1 has the resistance value of the motor pre-stored. After obtaining the current value detected by the current detection sensor, the processor 1 can calculate the power using the formula P = I. 2 R is used to calculate the electrical load, where P is the electrical load, I is the current value, and R is the resistance value.

[0077] In another embodiment of the present invention, the motor load detection device 2 is a voltage detection sensor. The voltage detection sensor can detect the voltage value of the motor when the roller is rolling. After the voltage detection sensor completes the detection, it sends the voltage value to the processor 1. The processor 1 has the resistance value of the motor pre-stored in its memory. After obtaining the voltage value detected by the voltage detection sensor, the processor 1 can calculate the power according to the formula P = U. 2 / R calculates the electrical load, where P is the electrical load, U is the voltage value, and R is the resistance value.

[0078] In another embodiment of the present invention, the motor load detection device 2 is an IPM (Intelligent Power Module), which can directly obtain the power value in the motor and send it to the processor 1.

[0079] This invention provides a control method and a garment processing device for garment processing equipment. The method controls the rollers of the garment processing equipment to be in a first working state and a second working state, and determines the first working parameters and the second working parameters of the rollers in the two working states. Then, the filter clogging status of the garment processing equipment is determined based on the difference between the first working parameters and the second working parameters. The above control method is simple and easy to implement, and can avoid problems such as the garment processing equipment operating with a dirty and clogged filter for a long time and increased power consumption, which is beneficial to improving the user experience.
