During the drying process, different types of clothing experience varying degrees of wear and tear. Materials with more delicate or easily shed fibers, such as sweaters and woolen garments, are more prone to producing lint during drying. Lint collectors are installed at the door seal to collect the lint generated during the drying process. When the lint collector accumulates too much lint, it can lead to decreased drying efficiency, increased energy consumption, and may even damage the machine. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0037] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0038] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0039] Figure 1 A flowchart of a lint removal method according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0040] In step S102, during the first stage of wire chip detection, a preliminary inspection of the wire chip accumulation is conducted.

[0041] In this embodiment, during the drying process of the clothes, the drying equipment initiates a detection of lint accumulation. First, there is a preliminary lint detection stage, in which the lint accumulation is preliminarily assessed. The purpose of this preliminary detection is to determine the presence of lint.

[0042] If no lint is detected, the initial testing phase continues. If lint is detected, the second phase begins, where further testing is conducted to determine if lint removal is necessary.

[0043] In step S104, in response to the first detection result of the preliminary detection, the second detection stage of wire debris is entered, which has higher detection accuracy than the first detection stage of wire debris.

[0044] In this embodiment, if the initial detection result indicates the presence of wire debris, the system proceeds to the second wire debris detection stage. The second wire debris detection stage has higher detection accuracy and can detect the accumulation of wire debris from another dimension, thereby determining whether to clean it and the cleaning strategy.

[0045] If no lint is detected in the first lint detection stage, the detection continues without proceeding to the second lint detection stage.

[0046] In step S106, in response to the second detection result of the second detection stage, the drying program is controlled to stop running and the lint cleaning device is started for automatic cleaning; or, in response to the third detection result of the second detection stage, the drying program is controlled to continue running until it stops, and then the lint cleaning device is started for automatic cleaning.

[0047] In this embodiment, the second detection result of the second detection stage indicates that the lint needs to be cleaned up promptly. In this case, the drying program is stopped and the lint cleaning device is activated for automatic cleaning.

[0048] If the other test results in the second testing phase can also include cases where it is not necessary to clean up the lint in a timely manner.

[0049] The technical solution described above includes a first wire shavings detection stage and a second wire shavings detection stage. The first detection stage detects the presence of wire shavings, while the second detection stage determines whether the wire shavings need to be cleaned and when to clean them. This improves the accuracy of wire shavings detection, facilitates the development of more scientific wire shavings cleaning strategies, and enables timely wire shavings removal, thereby improving the efficiency of the drying equipment and saving energy.

[0050] In one embodiment, during the first detection stage of the aforementioned wire debris, an infrared sensing device is used to perform a preliminary detection of the wire debris accumulation.

[0051] See appendix Figure 2The lint collection structure includes: a primary lint collection box 21, a secondary lint collection box 22, and a baffle mechanism 23. An infrared sensor 24, comprising an infrared emitting tube and an infrared receiving tube, can be installed on the inner wall of the primary lint collection box 21. After the drying equipment starts operating, the infrared emitting tube emits infrared light, converting electrical energy into infrared light. Simultaneously, the infrared receiving tube begins to receive infrared light. When the infrared signal illuminates the surface of the receiving tube, a photoelectric effect is generated, forming a photocurrent. This photocurrent, after amplification and filtering, can be identified as a specific signal by a decoder, thus achieving the sensing effect. As drying progresses, lint gradually accumulates on both sides of the lint collector, weakening the transmission of infrared light. As the infrared light gradually weakens, the information received by the infrared receiving tube also gradually weakens, causing the resulting photocurrent to change. Because the distribution of lint accumulation in the lint collector is uneven, it is difficult to determine whether the change in photocurrent has an absolute impact on drying efficiency. A second lint detection stage is needed to further determine whether to initiate the automatic lint cleaning process. When the photocurrent reaches a certain threshold, it will sense the accumulation of wire debris from the second dimension.

[0052] In the second stage of the above-mentioned wire debris detection, an air velocity detection device is used to accurately detect the accumulation of wire debris.

[0053] See appendix Figure 3 An anemometer 25 is installed at one end of the lint collector, on the side where the airflow passes. When the photocurrent change during the first lint detection stage reaches a certain threshold, the second lint detection stage is initiated. An anemometer with a thermal probe is installed at one end of the lint collector, on the side where the airflow passes. As the drying process progresses, lint accumulation causes a significant decrease in airflow velocity, thus affecting the airflow velocity and volume changes during the drying process. Airflow velocity detection can further determine the extent of lint accumulation.

[0054] In one implementation, see Appendix Figure 4 In step S102, before conducting a preliminary inspection of the wire chip accumulation in the first wire chip detection stage, the above method may further include the following steps:

[0055] In step S1022, the load weight is obtained.

[0056] In this embodiment, a weighing sensor can be used to detect the load weight inside the dryer.

[0057] In step S1024, the predetermined load weight range to which the above-mentioned load weight belongs is determined.

[0058] In step S1026, the first result of the first detection stage of the above-mentioned wire chip detection, the second result of the second detection stage of the above-mentioned wire chip detection, and the third detection result are determined for each load weight range.

[0059] In this embodiment, for each load weight range, a first result of the first detection stage of the above-mentioned thread chip detection, a second result of the second detection stage of the above-mentioned thread chip detection, and a third detection result can be set.

[0060] The drying efficiency is affected by lint accumulation to varying degrees depending on the load weight, thus requiring different lint cleaning strategies. With a light load weight, lint accumulation has a smaller impact on drying efficiency, so automatic lint cleaning can be performed after drying is complete. However, with a heavy load weight, lint accumulation significantly impacts drying efficiency. Therefore, automatic lint cleaning must be initiated immediately upon detecting a threshold during the drying process to ensure both drying efficiency and energy savings. Consequently, the timing of lint cleaning varies depending on the load weight range. Different load weight ranges are associated with different first detection stages, second detection stages, and third detection stages for lint.

[0061] In some embodiments, in step S206, the first result of the first detection stage of the wire chip detection phase corresponding to each load weight range, the second result of the second detection stage of the wire chip detection phase, and the third detection result may further include the following steps:

[0062] When the load weight is within the first load weight range, the first result of the first detection stage of the above-mentioned wire debris is that the induced current value of the infrared sensing device is less than or equal to the predetermined first current threshold.

[0063] The second result of the above-mentioned second stage of the wire debris detection is that the wind speed detected by the above-mentioned wind speed detection device is equal to or less than the predetermined first wind speed threshold, and less than or equal to the predetermined second wind speed threshold.

[0064] The third result of the above-mentioned second stage of the wire debris detection is that the wind speed is equal to or less than a predetermined first wind speed threshold and greater than a predetermined second wind speed threshold.

[0065] If the load weight falls within the first load weight range, the first lint removal strategy shall be adopted.

[0066] In this embodiment, the first load weight range can be 0-3KG.

[0067] See appendix Figure 5 In step S202, in the first lint cleaning strategy described above, the infrared sensing device is activated.

[0068] In step S204, in response to the infrared sensing device's sensing current value being less than or equal to a predetermined first current threshold X1, the second detection stage of wire debris is entered, and the wind speed detection device is activated to detect the wind speed.

[0069] In step S206, in response to the wind speed being equal to or less than a predetermined first wind speed threshold Y1 and less than or equal to a predetermined second wind speed threshold Y2, the dryer is controlled to stop running the drying program and the fully automatic lint cleaning device is started to perform automatic cleaning.

[0070] In this embodiment, if the wind speed is equal to or less than a predetermined first wind speed threshold Y1 and less than or equal to a predetermined second wind speed threshold Y2, it indicates that the lint accumulation is relatively serious, and the drying program needs to be stopped immediately, and the fully automatic lint cleaning device should be started for automatic cleaning.

[0071] In step S208, in response to the wind speed being equal to or less than a predetermined first wind speed threshold Y1 and greater than a predetermined second wind speed threshold Y2, the dryer is controlled to continue running the drying program until it stops, and then the fully automatic lint cleaning device is started to perform automatic cleaning.

[0072] In this embodiment, if the wind speed is equal to or less than a predetermined first wind speed threshold and greater than a predetermined second wind speed threshold Y2, it indicates that the current lint accumulation is acceptable, and the dryer can be controlled to continue running the drying program until it stops. Then, the fully automatic lint cleaning device will be started for automatic cleaning.

[0073] In step S210, in response to the wind speed being greater than the predetermined first wind speed threshold Y1, the process returns to the first detection stage of the thread debris.

[0074] In step S212, during the first detection stage, in response to the induced current value of the infrared sensing device being less than or equal to a predetermined second current threshold X2, the second detection stage of the wire debris is entered.

[0075] The fully automatic lint cleaning device, after completing the automatic cleaning, simultaneously starts the first and second lint detection stages to test whether the conditions for continuing drying have been met.

[0076] See appendix Figure 6 When the dryer starts, it weighs the clothes to determine their weight (0-3kg). Lint accumulates at the lint filter, and the system enters the first lint detection stage. The infrared sensor is activated to determine if the induced current is less than or equal to the first current threshold X1. If not, it returns to the previous step and continues the detection. It then determines if the induced current is less than or equal to the second current threshold X2. If yes, it enters the second lint detection stage. If it is greater than the second current threshold X2, it returns to the first lint detection stage to continue the detection.

[0077] If the induced current is less than or equal to the first current threshold X1, the system enters the second lint detection stage. The wind speed detection device is activated to measure the wind speed and determine if it is less than or equal to the first wind speed threshold Y1. If it is greater than the first wind speed threshold Y1, the system returns to the first detection stage and continues detection. If it is less than or equal to the first wind speed threshold Y1, the system determines if it is less than or equal to the second wind speed threshold Y2. If it is less than or equal to the second wind speed threshold Y2, the fully automatic lint cleaning device is activated directly. If it is greater than the second wind speed threshold Y2, the fully automatic lint cleaning device is activated after the program finishes running.

[0078] In some embodiments, in step S206, the first result of the first detection stage of the wire chip detection phase corresponding to each load weight range, the second result of the second detection stage of the wire chip detection phase, and the third detection result may further include the following steps:

[0079] When the load weight falls within the second load weight range;

[0080] The first result of the first stage of the above-mentioned wire chip detection is that the induced current value of the infrared sensing device is less than or equal to the predetermined third current threshold.

[0081] The second result of the above-mentioned second stage of the wire debris detection is that the wind speed detected by the above-mentioned wind speed detection device is equal to or less than a predetermined third wind speed threshold, and less than or equal to a predetermined fourth wind speed threshold.

[0082] The third result of the second stage of the above-mentioned wire debris detection is that the wind speed is equal to or less than the predetermined third wind speed threshold, and greater than the predetermined fourth wind speed threshold.

[0083] In some embodiments, if the load weight falls within a second load weight range, a second lint removal strategy is employed.

[0084] In this embodiment, the second load weight range can be 3-6KG.

[0085] See appendix Figure 7 In step S402, in the second lint cleaning strategy described above, the infrared sensing device is activated.

[0086] In step S404, in response to the infrared sensing device's sensing current value being less than or equal to a predetermined third current threshold X3, the second chip detection stage is entered, and the wind speed detection device is activated to detect the wind speed.

[0087] In this embodiment, it is determined whether the induced current value of the infrared sensing device is greater than a predetermined third current threshold X3. If yes, the induced current value of the infrared sensing device is greater than the predetermined third current threshold X3, and the first stage of wire chip detection continues. If no, the steps in step S404 are executed.

[0088] In step S406, in response to the wind speed being equal to or less than a predetermined third wind speed threshold Y3 and less than or equal to a predetermined fourth wind speed threshold Y4, the dryer is controlled to stop running the drying program and the fully automatic lint cleaning device is started to perform automatic cleaning.

[0089] In step S408, in response to the wind speed being equal to or less than the predetermined third wind speed threshold Y3 and greater than the predetermined fourth wind speed threshold Y4, the dryer is controlled to continue running the drying program until it is completed, and the fully automatic lint cleaning device is started to perform automatic cleaning.

[0090] See appendix Figure 8 The dryer starts, weighs the clothes to determine their weight, and confirms that the clothes weigh 3-6kg. Lint accumulates at the lint filter, and the first lint detection stage begins. The infrared sensor is activated to determine whether the induced current has reached the third current threshold X3. If not, it returns to the previous step and continues the detection.

[0091] If the induced current reaches the third current threshold X3, the system enters the second stage of lint detection. The wind speed detection device is activated to measure the wind speed and determine if it is less than or equal to the third wind speed threshold Y3. If not, the system returns to the previous step and continues detection. If it is, the system determines if the wind speed is less than or equal to the fourth wind speed threshold Y4. If the wind speed is less than or equal to the fourth wind speed threshold Y4, the fully automatic lint cleaning device is activated directly. If the wind speed is equal to or less than the predetermined third wind speed threshold Y3, but greater than the fourth wind speed threshold Y4, the fully automatic lint cleaning device is activated after the program finishes running.

[0092] In some embodiments, in step S206, the first result of the first detection stage of the wire chip detection phase corresponding to each load weight range, the second result and the third detection result of the second detection stage of the wire chip detection phase include:

[0093] When the load weight is within the third load weight range, the first result of the first detection stage of the above-mentioned wire debris is that the induced current value of the infrared sensing device is less than or equal to the predetermined fourth current threshold.

[0094] The second result of the above-mentioned second stage of the wire debris detection is that the wind speed is equal to or less than the predetermined fifth wind speed threshold.

[0095] In some embodiments, if the load weight falls within a third load weight range, a third lint removal strategy is employed.

[0096] In this embodiment, the third load weight range is 6-10KG.

[0097] See appendix Figure 9In step S602, in the third lint cleaning strategy, the infrared sensing device is activated.

[0098] In step S604, in response to the induced current value of the infrared sensing device being less than or equal to the predetermined fourth current threshold X4, the second detection stage of wire debris is entered, and the wind speed detection device is activated to detect the wind speed.

[0099] In this embodiment, if the induced current value of the infrared sensing device is greater than the predetermined fourth current threshold X4, the detection in the first detection stage continues.

[0100] In step S606, in response to the wind speed being equal to or less than the predetermined fifth wind speed threshold Y5, the drying program is controlled to stop running, and the fully automatic lint cleaning device is started to perform automatic cleaning.

[0101] In this embodiment, if the wind speed is equal to or less than the predetermined fifth wind speed threshold Y5, it indicates that the lint accumulation is relatively serious. Continuing to run the drying program in this way poses a significant risk and could easily lead to an accident or malfunction. It is necessary to immediately stop the dryer's drying program and immediately activate the fully automatic lint cleaning device for automatic cleaning.

[0102] In some embodiments, if the aforementioned wind speed exceeds a predetermined fifth wind speed threshold Y5, it indicates that the lint accumulation is not particularly severe. The dryer can continue running the drying program. The dryer is controlled to continue running the drying program until it is completed, at which point the fully automatic lint cleaning device is activated for automatic cleaning.

[0103] In this embodiment, the load weight is large, and the impact of lint on drying will be greater. In this case, only one threshold is set for each of the first and second lint detection stages.

[0104] See appendix Figure 10 In the middle, the dryer starts, weighs and determines the weight of the clothes. If the weight of the clothes is 6-10kg, the lint accumulates at the lint filter and enters the first lint detection stage. The infrared sensor is activated to determine whether it is less than or equal to the fourth current threshold X4. If not, it returns to the previous step and continues to detect.

[0105] If the current threshold value is less than or equal to the fourth current threshold value X4, the system proceeds to the second stage of lint detection. The wind speed detection device is activated to measure the wind speed and determine if it reaches the fifth wind speed threshold value Y5. If yes, the fully automatic lint cleaning device is activated directly. If no, the system returns to the previous step and continues the detection process.

[0106] See Table 1 for a summary of thresholds.

[0107]

[0108] Among them, the first current threshold X1 > the second current threshold X2 > the third current threshold X3 > the fourth current threshold X4. The first wind speed threshold Y1 > the second wind speed threshold Y2 > the third wind speed threshold Y3 > the fourth wind speed threshold Y4 > the fifth wind speed threshold Y5.

[0110] The first detection module 81 is used to perform preliminary detection of the wire chip accumulation in the first stage of wire chip detection.

[0111] The second detection module 82 is used to respond to the first detection result of the above preliminary detection and enter the second detection stage of wire debris. The second detection stage has higher detection accuracy than the first detection stage. The first detection result indicates that the wire debris accumulation has reached the preset condition.

[0112] The control module 83 is used to respond to the second detection result of the second detection stage mentioned above, control the dryer to stop running the drying program and start the lint cleaning device for automatic cleaning.
