[0027] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] Figure 1 This is a flowchart illustrating an airflow detection method provided in an embodiment of this disclosure. Figure 1 As shown, this airflow detection method includes, but is not limited to, the following steps:

[0030] S101, Obtain the first temperature when the heating element starts heating.

[0031] In some embodiments, the garment handling device is controlled to enter the drying program and the fan is started. After the fan is started, the heating element can be turned on, and the first temperature at which the heating element begins to heat is recorded.

[0032] In some embodiments, the garment handling device needs to have a drying function, such as a drum washing machine, a garment spin dryer, a washer-dryer combo, a dryer, a dry cleaning machine, etc., but this disclosure does not limit this.

[0033] Optionally, the clothes handling device can be a partitioned twin-drum washing machine, including a first drum and a second drum.

[0034] Optionally, the capacity of the first roller is greater than the capacity of the second roller; that is, the first roller is a large roller and the second roller is a small roller. Optionally, the capacity of the second roller, or small roller, can be 1 to 10 liters.

[0035] It should be noted that the roller consists of an inner cylinder and an outer cylinder. The inner cylinder is removed from the outer cylinder, and the lifting ribs in the inner cylinder are removed. Then, water is poured into the inner cylinder. The amount of water required to fill the inner cylinder is the capacity of the roller.

[0036] In some embodiments, it can be determined whether the garment handling device is currently in the drying program based on user instructions. These user instructions may include, but are not limited to, contact-based and non-contact-based instructions. Furthermore, the drying program selected by the user may be a standalone drying program or a wash-dry program that combines washing and drying.

[0037] In some embodiments, the user's voice commands can be monitored, and keywords such as "clothes drying", "drying", and "clothes heating" can be identified from the voice commands to determine whether the clothes handling device has entered the drying program.

[0038] In some embodiments, the user's posture can be monitored, and a mapping relationship between posture and washing stage can be established in advance. If the user makes a posture that matches the drying stage, the garment handling device can be determined to enter the drying program. Optionally, the posture can be a gesture, body posture, or posture of a specific body part such as the head.

[0039] In some embodiments, the washing process of the garment handling device can be monitored, and in response to the garment handling device completing the spin-drying process, it can be determined that the garment handling device has entered the drying process.

[0040] In some embodiments, the user's instruction can be a selection of the washing stage, and further, the selection determines whether the garment handling device is currently in the drying program. For example, the user can directly select the "Clothes Drying" button on the control panel, or rotate to the "Clothes Drying" position. This selection operation instructs the garment handling device to enter the drying program. As another example, the user can select the drying stage on a client device associated with the garment handling device.

[0041] Furthermore, after the garment handling device enters the drying program, the fan can be started to blow air into the drum through the drying tunnel to dry the clothes inside the drum.

[0042] In some embodiments, after entering the drying process and starting the fan, the first temperature of the target area when the heating element begins to heat can be collected.

[0043] In some embodiments, the heating element may include, but is not limited to, a heating tube, the heating part of a heat pump system, or a positive temperature coefficient (PTC) heater.

[0044] In some embodiments, the target area includes, but is not limited to, the drying duct and / or rollers of the garment processing device.

[0045] In some embodiments, the temperature sensor may be located within a designated area of ​​the rollers and / or drying duct of the garment handling apparatus. For example, it may be deployed in the central area of ​​the roller or the bottom area of ​​the roller. Alternatively, it may be deployed in the middle area of ​​the drying duct or at the outlet end.

[0046] In some embodiments, temperature sensors may be evenly distributed within the drums and / or drying tunnels of the garment handling apparatus.

[0047] S102, obtain the second temperature after the heating element has been operating for a first set time.

[0048] In some embodiments, after the fan is turned on, the heating element can continue to operate, and the operating time of the heating element can be timed. After the heating element has operated for a first set time, a second temperature can be collected. That is, when the heating element has operated for the first set time, the second temperature of the target area can be collected by a sensor installed at the target area. It can be understood that the second temperature gradually increases from the first temperature under the influence of the heating element, meaning the second temperature will be greater than the first temperature.

[0049] S103, determine whether the air volume of the fan is abnormal based on the first temperature and the second temperature.

[0050] In some embodiments, heat from the heating element is blown onto the drum by a fan to raise the temperature inside the drum, thereby drying the clothes. When the fan is operating normally, the temperature inside the drum or drying tunnel rises after being heated by the heating element. The fan's airflow can then be detected based on the temperature difference between a first temperature and a second temperature. In other words, the fan's airflow is determined to be sufficient or abnormal based on the temperature difference. For example, a large temperature difference indicates that the fan is blowing out enough air to deliver heat from the heating element into the drum, quickly raising the first temperature to the second temperature, thus indicating that the fan's airflow is normal. Conversely, a small temperature difference indicates that the fan is blowing out insufficient or too little air, preventing the heat from the heating element from fully reaching the drum, thus preventing the first temperature from rising quickly to the second temperature, thus indicating that the fan's airflow is abnormal.

[0051] In some embodiments, the temperature rise value between the second temperature and the first temperature can be obtained, that is, the temperature difference between the second temperature and the first temperature can be obtained as the temperature rise value. If the temperature rise value is greater than or equal to the first set temperature, it can be determined that the fan's airflow is normal; if the temperature rise value is less than the first set temperature value, it can be determined that the fan's airflow is abnormal.

[0052] In some embodiments, the temperature rise value between the second temperature and the first temperature is obtained. Further, the heating rate is obtained based on the temperature difference and a first set time. In response to the heating rate being greater than or equal to a set speed value, it is determined that the air volume of the fan is normal; in response to the heating rate being less than the set speed value, it is determined that the air volume of the fan is abnormal.

[0053] In some embodiments, the ratio between the second temperature and the first temperature is obtained. If the ratio is greater than or equal to a set ratio, it is determined that the air volume of the fan is normal. If the temperature rise is less than the set ratio, it is determined that the air volume of the fan is abnormal.

[0054] In this embodiment of the present disclosure, during the initial stage of drying, the initial first temperature inside the drum and the second temperature after heating by the heating element can be monitored. By measuring the difference between the two temperatures, the airflow of the fan can be detected to determine whether there is an abnormality in the airflow, so as to facilitate the maintenance or cleaning of the clothing processing device.

[0055] Figure 2 A flowchart illustrating another airflow detection method provided in this disclosure embodiment. Figure 2 As shown, this airflow detection method includes, but is not limited to, the following steps:

[0056] S201, control the garment handling device to enter the drying program and start the fan to work.

[0057] For optional implementations of step S201, please refer to [link / reference]. Figure 1 Optional implementation methods of step S101, and Figure 1 Other related parts in the embodiments involved will not be described in detail here.

[0058] S202: After the fan has been working for the second set time, the heating element is turned on and the first temperature is collected simultaneously.

[0059] In some embodiments, after the fan is turned on, the operating time of the fan can be timed. After the fan has operated for a second set time, the heating element is turned on. Furthermore, the first temperature of the target area is simultaneously collected, that is, the temperature inside the drying tunnel or drum is collected when the heating element is turned on. It can be understood that after the fan has operated for the second set time, the fan can reach a normal operating state. When the fan is operating normally, the heating element can be turned on to ensure that the heat provided by the heating element can be quickly blown into the drum to dry the clothes.

[0060] S203, after the heating element has been operating for a first set time, the heating element is turned off and a second temperature is obtained.

[0061] In some embodiments, after the heating element has been operating for a first set period of time, in order to avoid the influence of the heating element on the subsequent temperature rise value and to ensure the accuracy of the subsequent airflow detection, the heating element can be turned off first, and the second temperature can be collected at the same time as the heating element is turned off.

[0062] S204, obtain the temperature rise values ​​of the second temperature and the first temperature.

[0063] S205, determine whether the temperature rise value is greater than or equal to the first set temperature value.

[0064] If the temperature rise is greater than or equal to the first set temperature value, step S206 can be executed; if the temperature rise is less than the first set temperature value, step S207 can be executed.

[0065] S206, confirm that the fan's airflow is normal, and restart the heating element to continue drying.

[0066] In some embodiments, the temperature rise value between the second temperature and the first temperature can be obtained, that is, the temperature difference between the second temperature and the first temperature can be obtained as the temperature rise value. If the temperature rise value is greater than or equal to the first set temperature value, it can be said that the temperature rise value is large, indicating that the air volume blown by the fan is large enough to blow the heat of the heating element into the drum normally, and can raise the first temperature to the second temperature relatively quickly, thereby determining that the air volume of the fan is normal.

[0067] Furthermore, if the fan's airflow is confirmed to be normal, the heating element can be restarted to continue the subsequent drying program and dry the clothes inside the drum.

[0068] S207, if the fan's airflow is found to be abnormal, generate an abnormal airflow warning message, and restart the heating element to continue drying.

[0069] In some embodiments, if the temperature rise is less than the first set temperature value, it can be said that the temperature rise is small, indicating that the air volume blown by the fan is insufficient or less, and the heat of the heating element cannot be fully blown into the drum, resulting in the first temperature not rising to the second temperature quickly, thereby determining that the air volume of the fan is abnormal.

[0070] Furthermore, if the fan's airflow is found to be abnormal, an abnormal airflow warning message can be generated, and the heating element can be restarted to continue running the subsequent drying program to dry the clothes in the drum.

[0071] In this embodiment of the present disclosure, during the initial stage of drying, the initial first temperature inside the drum and the second temperature after heating by the heating element can be monitored. By measuring the difference between the two temperatures, the airflow of the fan can be detected to determine whether there is an abnormality in the airflow. When an abnormality in the airflow is detected, an abnormality alert message can be sent to the user to remind the user to perform maintenance or clean foreign objects such as lint in the clothing processing device.

[0072] Figure 3 A flowchart illustrating another airflow detection method provided in this disclosure embodiment. Figure 3 As shown, this airflow detection method includes, but is not limited to, the following steps:

[0073] S301 controls the garment handling device to enter the drying program and starts the fan to work.

[0074] For optional implementations of step S301, please refer to [link / reference]. Figure 1 Optional implementation methods of step S101, and Figure 1 Other related parts in the embodiments involved will not be described in detail here.

[0075] S302: After the fan has been working for the second set time, the heating element is turned on and the first temperature is collected simultaneously.

[0076] For optional implementations of step S302, please refer to [link / reference]. Figure 2 Optional implementation methods of step S202, and Figure 2 Other related parts in the embodiments involved will not be described in detail here.

[0077] S303: After the heating element has been operating for a first set time, the heating element is controlled to turn off, and a second temperature is obtained.

[0078] For optional implementations of step S302, please refer to [link / reference]. Figure 2 Optional implementation methods of step S202, and Figure 2 Other related parts in the embodiments involved will not be described in detail here.

[0079] S304, obtain the temperature rise values ​​of the second temperature and the first temperature.

[0080] S305 determines whether the temperature rise value is greater than or equal to the first set temperature value.

[0081] If the temperature rise is greater than or equal to the first set temperature value, step S306 can be executed; if the temperature rise is less than the first set temperature value, step S307 can be executed.

[0082] S306, confirming that the fan's airflow is normal.

[0083] S307, restart the heating element to continue drying.

[0084] S308, confirm that the fan's airflow is abnormal and generate an abnormal airflow warning message.

[0085] S309, determine whether the temperature rise value is less than or equal to the second set temperature value.

[0086] In some embodiments, after determining that the airflow is abnormal, the temperature rise value can be used to further identify whether the fan's airflow is particularly low. The temperature rise value can be compared with a second set temperature value, which is understood to be lower than a first set temperature value. If the temperature rise value is less than or equal to the second set temperature value, it can be determined that the fan's airflow is particularly low.

[0087] If the temperature rise is less than or equal to the second set temperature value, step S310 can be executed; if the temperature rise is greater than or equal to the first set temperature value, step S307 can be executed.

[0088] S310 controls the drying program to stop running.

[0089] In some embodiments, if the air volume of the fan is found to be particularly small by further identifying the temperature rise value, the drying process will be completed immediately, but the drying effect of the clothes will not be good. Or, if the temperature inside the drum cannot reach the drying end threshold for a long time due to the small air volume, the drying process will continue to run. In this embodiment of the present disclosure, the drying process can be stopped when the air volume of the fan is found to be particularly small.

[0090] In this embodiment, during the initial drying stage, the initial first temperature inside the drum and the second temperature after heating by the heating element can be monitored. The difference between these two temperatures allows for anomaly detection of the fan's airflow, thus determining if any abnormalities exist. Upon detecting an abnormal airflow, a notification can be sent to the user to remind them to perform maintenance or clean lint and other foreign objects from the clothing handling device. Furthermore, if the fan's airflow is detected to be particularly low, the drying program can be stopped, thereby saving energy and preventing damage to clothing caused by prolonged drying or tumbling within the drum.
