[0042] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0044] The technical solution provided by the embodiments of the present disclosure is applicable to a clothing processing device having a filter and a fan. The fan is used to transmit flowing air to the filter, and the filter is used to filter impurities such as lint in the air duct. In addition, the clothing processing device also includes a recording component for storing and recording the number of drying program runs, and a detection component for detecting the operating status of the fan. The detection component can combine the number of drying program runs and the operating status of the fan to determine whether the filter is clogged, thereby effectively detecting filter clogs. For example, the clothing processing device may include a dryer, a heat pump washer-dryer, or other equipment with a drying function, which is not limited here.

[0045] In particular, for different types of equipment with drying functions, taking dryers and heat pump washer-dryers as examples, the internal structure of the heat pump washer-dryer is more compact and its filter is smaller, making it more prone to filter clogging.

[0046] The filter clogging detection method provided in the embodiment of the present disclosure determines that the filter is clogged and gives a corresponding prompt to the user when the number of times the drying program is run is greater than or equal to the preset number of times and the fan meets the preset state, so that the user can clean the filter in time to allow the internal air to circulate effectively, thereby improving the drying effect.

[0047] In some embodiments, before the clothing processing device issues the first prompt message, it is also necessary to obtain the filter status data, determine whether the filter is not in the preset installation position for a duration greater than or equal to the first preset duration, and determine that the filter has been cleaned, then reset the number of times the drying program is run, thereby initializing the number of times the drying program is run.

[0048] In some embodiments, the conditions under which the fan meets the preset state include but are not limited to: the operating power of the fan is less than or equal to the preset power, the current of the fan is less than or equal to the preset current, and the noise loudness amplitude of the fan in the preset frequency range is greater than or equal to the preset loudness threshold.

[0049] In some embodiments, when the drying program is started, by obtaining the filter status data and determining that the filter is not in the preset installation position, a second prompt message is issued to prompt that the filter is not in the preset installation position, and the clothes processing device is controlled not to start the drying operation; and / or, during the running of the drying program, by obtaining the filter status data and determining that the filter is not in the preset installation position, a corresponding second prompt message is issued, and when it is determined that the filter is not in the preset installation position for a duration greater than or equal to the second preset duration, the clothes processing device is controlled to stop the drying operation.

[0050] The filter clogging detection method, device, medium and equipment provided by the embodiments of the present disclosure are exemplarily described below with reference to the accompanying drawings.

[0051] Figure 1 This is a flow chart of a filter clogging detection method provided by an embodiment of the present disclosure. The filter clogging detection method is applicable to a clothing processing device that includes at least a filter and a fan. The filter clogging detection method can be executed by a related detection device, specifically by a controller of the clothing processing device. The detection device can be implemented in software and / or hardware. Figure 1 The filter clogging detection method may include the following steps:

[0052] S110: Obtain the number of drying program runs and the fan operating status.

[0053] The number of drying program runs is stored and recorded by a related recording component. For example, the number of drying program runs can be stored and recorded by a storage chip, i.e., a memory. In other embodiments, other components with storage and recording functions known to those skilled in the art can also be used, which is not limited here.

[0054] The fan operating status is detected by relevant detection components. For example, a frequency converter can be used to detect the fan operating status, for example, to detect whether the fan's operating power, current, etc. are normal. In other embodiments, other components with the above detection functions known to those skilled in the art can also be used, which are not detailed or limited here.

[0055] In this way, by obtaining the number of times the drying program is run and the operating status of the fan, it is convenient for subsequent corresponding steps to judge the filter blockage condition based on this. The specific judgment process of the filter blockage condition will be explained in detail later.

[0056] S120: Based on the drying program running times being greater than or equal to a preset number of times and the fan being in a preset state, a first prompt message is issued.

[0057] The preset number of times is at least 3 to increase the accuracy of filter clogging detection. For example, the preset number of times can be 3, 4, 5, or other times. Specifically, if the preset number of times is 3, then the drying program should be run 3 times or more. This setting can be set according to the filter clogging detection requirements of the clothing processing equipment and is not limited here.

[0058] It should be noted that the preset state is a state in which the fan is operating abnormally, and the fan conforming to the preset state occurs at any time during at least a preset number of drying program runs. For example, assuming the preset number is three and the drying program is run three times, the fan conforming to the preset state occurs at any time during at least three drying program runs. Specifically, the fan conforming to the preset state may occur during the first drying program run, the second drying program run, or the third drying program run. It is sufficient that the fan conforms to the preset state during any of the above drying program runs, and this is not limited here.

[0059] On the contrary, if the drying program runs more than or equal to the preset number of times and the fan does not meet the preset state, it indicates that the filter is not blocked. At this time, the clothing processing device will not issue the first prompt message, and the clothing processing device can be controlled to continue the drying process until the drying is completed.

[0060] The first prompt message is used to prompt the user that the filter is clogged, indicating that the filter needs to be cleaned. For example, the first prompt message may only prompt the user that the filter is clogged, or may only prompt that the filter needs to be cleaned. Preferably, the first prompt message may also prompt that the filter is clogged and that the filter needs to be cleaned, which is not limited here.

[0061] It can be understood that when the drying program has been run a predetermined number of times or more and the fan is in a predetermined state, the filter is determined to be clogged and a first prompt is issued. Thus, by combining the drying program run count and the fan operating state, effective detection of filter clogs is achieved, thereby promptly notifying the user of clogged filters and prompting them to clean them, thus ensuring the proper operation of the clothing processing device.

[0062] For example, the clothing processing device can also communicate with the terminal device. Specifically, the terminal device is installed with an application (APP) software for the clothing processing device. The application software realizes information exchange between the terminal device and the clothing processing device by connecting to the clothing processing device or communicating with the clothing processing device in a short distance through a local area network. In this regard, the first prompt information can be directly issued by the clothing processing device, or the clothing processing device communicates with the terminal device and the first prompt information is issued through the corresponding application software of the terminal device. The prompt can be specifically in the form of text or voice, etc., which is not limited here.

[0063] It should be noted that after the first prompt message is issued in this step, if the user still has not cleaned the filter, the next time the clothing processing device is started, the clothing processing device will issue the first prompt message again to remind the user to clean the filter in time; correspondingly, the corresponding application software of the terminal device will also synchronously issue the first prompt message.

[0064] The filter clogging detection method provided by the disclosed embodiment includes: obtaining the number of drying program runs and the fan operating status; and issuing a first prompt message based on the drying program running number being greater than or equal to a preset number of times and the fan being in a preset state; wherein the first prompt message is used to indicate filter clogging. Thus, when the drying program running number is greater than or equal to the preset number of times and the fan is in a preset state, the filter is determined to be clogged and a corresponding prompt is issued to the user, allowing the user to promptly clean the filter, allowing for effective internal air circulation and thereby improving the drying effect.

[0065] In some embodiments, Figure 1 On the basis of the above, before the first prompt message is issued in S120, the following steps are also included:

[0066] Step 1: Get filter status data.

[0067] The filter status data is data used to characterize the filter status. For example, the filter status data may include filter position information, time information of the filter position, etc. In other embodiments, the filter status data may also include other information related to the filter status known to those skilled in the art, which is not limited here.

[0068] It is understood that the filter is set in the filter box of the clothing processing device, and the filter box is usually equipped with a magnet. When the user needs to clean the filter, the filter box is usually taken out to clean the filter inside the filter box. For example, for the filter position information, a component that can sense magnets, such as a Hall sensor, can be used to sense the position of the filter box; for the time information of the filter position, a component that can measure time, such as a timer, can be used to calculate the duration of the filter (or filter box) in the corresponding position. In other embodiments, other components with the above sensing and timing functions known to those skilled in the art can also be used, which are not limited here.

[0069] Step 2: Determine based on the filter status data that the filter has been cleaned and reset the number of drying program runs.

[0070] Among them, if the filter (or filter box) is not in the preset installation position within a period of time, it is determined that the filter has been cleaned, thereby resetting the number of times the drying program is run. The specific judgment process for determining whether the filter has been cleaned will be described in detail later.

[0071] Resetting the drying program running times means clearing the drying program running times to zero. Specifically, by determining that the filter box has been cleaned and resetting the drying program running times, the drying program running times are initialized. On this basis, S110 and S120 above are executed in sequence to better achieve effective detection of filter blockage.

[0072] It is not difficult to understand that if the filter has not been cleaned, when executing S110 and S120 above in sequence, the preset number of times is also 3 times, and the drying program is run 3 times. Then, the fan meets the preset state which may occur during the first drying program operation. When the drying program is run 3 times, the first prompt message is issued; in this regard, if the user still has not cleaned the filter, the next time the clothes processing device is started, the clothes processing device and / or the terminal device will issue the first prompt message again to enable the user to clean the filter in time to ensure the drying effect of the clothes processing device.

[0073] In some embodiments, determining that the filter has been cleaned based on the filter status data in the above steps specifically includes the following steps:

[0074] Based on the filter status data, it is determined that the filter is not in the preset installation position for a duration greater than or equal to a first preset duration, and then it is determined that the filter has been cleaned.

[0075] The first preset time duration is used to measure the duration of time the filter is not in the preset installation position. Specifically, when the duration of time the filter is not in the preset installation position is greater than or equal to the first preset time duration, the duration of time the filter is not in the preset installation position is longer, indicating that the user has opened (or removed) the filter box and cleaned the filter; conversely, when the duration of time the filter is not in the preset installation position is less than the first preset time duration, the duration of time the filter is not in the preset installation position is shorter, indicating that the user has not cleaned the filter.

[0076] Exemplarily, the first preset time length may be within one minute, such as 6 seconds, 7 seconds or other more reasonable time lengths, so as to increase the probability of the user cleaning the filter and avoid misjudgment due to the first preset time length being set too short. For example, when the user only takes out the filter but does not clean it, a misjudgment that the filter has been cleaned may occur, or when the clothing processing equipment shakes during operation, causing the filter to temporarily deviate from the preset installation position, a misjudgment that the filter has been cleaned may occur.

[0077] Taking the first preset time length as 6 seconds for explanation, if the user pulls open the filter box for a duration greater than or equal to 6 seconds, the filter is not in the preset installation position for a duration greater than or equal to 6 seconds, thereby determining that the filter has been cleaned. It can be appropriately set according to the detection requirements of the filter blockage detection method provided in the embodiment of the present disclosure, and is not limited here.

[0078] It is not difficult to understand that the preset installation position is the designated installation position of the filter (or filter box) in the clothing processing device, which can be set according to the design requirements of the clothing processing device and is not limited here.

[0079] In some embodiments, reference Figure 1 , the fan in S120 meets the preset status, including the following situations:

[0080] The operating power of the fan is less than or equal to a preset power, and / or the current of the fan is less than or equal to a preset current.

[0081] It should be noted that when the filter is clogged, it will affect the gas circulation in the air duct, and then affect the operating status of the fan, which will be manifested as abnormal operation of the fan.

[0082] Among them, the preset power is used to measure the operating power of the fan. Similarly, the preset current is used to measure the current of the fan. The sizes of the preset power and preset current can be set according to the operating requirements of the fan and are not limited here.

[0083] Specifically, for the operating power of the fan, if the operating power of the fan is less than or equal to the preset power, it indicates that the operating power of the fan is abnormal. At this time, the fan is idling due to filter blockage, resulting in a smaller operating power of the fan; for the current of the fan, if the current of the fan is less than or equal to the preset current, it indicates that the current of the fan is abnormal. When the fan is idling due to filter blockage, resulting in a smaller operating power, the current of the fan is smaller.

[0084] In this way, by comparing the operating power of the fan with the preset power, and / or comparing the current of the fan with the preset current, it is judged whether the fan meets the preset state, and further, when it is determined that the fan meets the above preset state and the number of times the drying program is run is greater than or equal to the preset number of times, the first prompt message can be issued in time.

[0085] In particular, when it is determined that the fan meets the above preset conditions, a prompt message that only the filter needs to be cleaned can be immediately issued to timely reduce the adverse effects caused by filter blockage. For example, due to filter blockage, the air flow volume in the air duct is attenuated, which in turn causes the internal temperature of the clothing processing equipment to be too high, making it impossible to achieve effective heat exchange for the clothes, resulting in poor drying effect; when it is determined that the fan meets the above preset conditions and the number of times the drying program is run is greater than or equal to the preset number of times, a prompt message (i.e., the first prompt message) is issued again that the filter is blocked and the filter needs to be cleaned.

[0086] In some embodiments, continue to refer to Figure 1 , the fan in S120 meets the preset status, including the following conditions:

[0087] The fan noise loudness amplitude within the preset frequency range is greater than or equal to the preset loudness threshold.

[0088] The preset loudness threshold is used to measure the magnitude of the fan noise loudness. Here, the preset frequency range and the preset loudness threshold can be set according to the operating requirements of the fan and are not limited here.

[0089] It should be noted that fans usually include blades and a volute structure. When the filter is clogged, the air in the air duct cannot be circulated effectively, the air flow volume is attenuated, and negative pressure is formed in the fan volute. The wind resistance becomes smaller, which in turn leads to an increase in the fan speed and noise frequency. At the same time, the unbalanced excitation of the blades causes an increase in the noise loudness amplitude.

[0090] In this way, by comparing the noise loudness amplitude within the preset frequency range with the preset loudness threshold, it is judged whether the fan meets the preset state, so that when the fan meets the preset state, that is, the fan operation is abnormal, such as when the noise loudness amplitude of the fan in the preset frequency range is large, a prompt message is immediately issued to remind that the filter needs to be cleaned, so as to timely reduce the related adverse effects caused by filter blockage. Regarding the related operations performed by the clothing processing equipment when the fan meets the preset state, please refer to the corresponding content above for understanding, and no further details will be given here.

[0091] In combination with the corresponding embodiments above, it should be noted that when the fan meets the preset state, there are two situations included, namely, situation one: the operating power of the fan is less than or equal to the preset power, and / or the current of the fan is less than or equal to the preset current; situation two: the noise loudness amplitude of the fan in the preset frequency range is greater than or equal to the preset loudness threshold. It can be seen that these two situations are parallel schemes formed when determining that the fan meets the preset state. In this regard, any of the schemes can be combined to judge whether the filter is blocked.

[0092] In this way, by utilizing the above parallel scheme to determine whether the fan meets the preset state, and then determine that the filter is clogged, the method for determining whether the filter is clogged is enriched.

[0093] In some embodiments, the filter blockage detection method further includes the following steps:

[0094] Step 1: Get filter status data.

[0095] The filter status data includes filter position information, and the filter position information may specifically include information that the filter is in a preset installation position and information that the filter is not in the preset installation position.

[0096] Specifically, the clothing processing equipment usually includes a computer board with a main control function. Based on the use of a Hall sensor to sense the magnet inside the filter box, combined with the detection function of relevant pins of the computer board, such as the input / output (IO) pin, it further determines whether the filter box is in the preset installation position.

[0097] Step 2: Based on the filter status data, it is determined that the filter is not in the preset installation position, and a second prompt message is issued.

[0098] Combined with the above steps, when the filter is in the preset installation position, the filter box has not moved relative to the preset installation position, and the Hall sensor can sense the strong magnetism in real time; conversely, when the filter is not in the preset installation position, the filter box has moved relative to the preset installation position, indicating that the user may have removed the filter box. At this time, the distance between the Hall sensor and the filter box will usually increase, making it difficult for the Hall sensor to sense the strong magnetism, and thus the filter position can be sensed based on the above principle.

[0099] The voltage level of the input / output pins is correlated with whether the Hall sensor senses a strong magnet, thereby determining whether the filter is in the preset installation position. For example, when the Hall sensor senses a strong magnet, i.e., a magnet within the filter box, the input / output pins may detect a high voltage level, thereby confirming that the filter is in the preset installation position. Conversely, when the Hall sensor does not sense a strong magnet, i.e., a magnet within the filter box, the input / output pins may detect a low voltage level, thereby confirming that the filter is not in the preset installation position.

[0100] The second prompt message is used to remind the user that the filter is not in the preset installation position. In this way, when the filter is not in the preset installation position, the second prompt message can be sent to promptly remind the user to return the filter box to the preset installation position, which is conducive to the normal operation of the clothes processing device.

[0101] In some embodiments, in combination with the above steps, when the drying process is started, after the second prompt message is issued, the following steps are further included:

[0102] The clothes processing device is controlled not to start the drying operation.

[0103] Specifically, when the drying cycle is activated, if the filter is not detected in the preset installation position, a second prompt message is issued, and the clothes processing device is controlled not to start the drying operation. In this case, the clothes processing device cannot operate. In response, the user needs to return the filter box to the preset installation position and then press the button to start the drying cycle to start the drying operation of the clothes processing device.

[0104] It is not difficult to understand that by controlling the clothing processing equipment not to start the drying operation, the safety problems caused by continuing to dry while the filter box is removed are avoided. Specifically, it prevents hair debris from flying around and causing related components in the clothing processing equipment to be blocked, thereby causing machine failure or even spontaneous combustion.

[0105] In some embodiments, in combination with the above steps, during the drying process, after the second prompt message is issued, the following steps are further included:

[0106] It is determined that the filter is not in the preset installation position for a duration greater than or equal to a second preset duration, and the clothes processing device is controlled to stop the drying operation.

[0107] The second preset time duration is also used to measure the duration of time the filter is not in the preset installation position. It should be noted that the second preset time duration is greater than the first preset time duration. For example, if the first preset time duration is 6 seconds, the second preset time duration can be 1 minute or longer. For example, the second preset time duration can be 1 minute, 2 minutes, or other durations, which are not limited here.

[0108] In this way, based on the fact that the second preset time period is greater than the first preset time period above, it can be known that during the operation of the drying program, if the filter is not in the preset installation position for a short period of time and is less than the second preset time period, it indicates that the user may have cleaned the filter within the second preset time period and put it back to the preset installation position, or the clothing processing device may have shaken due to operation, causing the filter to temporarily deviate from the preset installation position and then return to the preset installation position. In this way, the probability of the filter returning to the preset installation position in time is increased, and the clothing processing device can continue to perform the drying operation after the filter returns to the preset installation position, thereby better ensuring the drying effect of the clothing processing device and improving the safety of use of the clothing processing device.

[0109] For example, the second preset time length may be the same as or different from the first preset time length above. The second preset time length may be 50 seconds, 60 seconds or other time lengths. Similarly, it is only necessary to ensure that the time length is not too short to increase the probability of the user cleaning the filter. Please refer to the setting principle of the first preset time length for understanding. It will not be repeated here and will not be limited.

[0110] Specifically, during the drying process, if the filter is detected to be not in the preset installation position, a second prompt message is issued. If it is determined that the filter has not been in the preset installation position for a period greater than or equal to the second preset time, indicating that the user has removed the filter box for a long period of time, the clothes processing device is controlled to stop the drying operation. In this case, the user must also return the filter box to the preset installation position and then press the button to start the drying process to allow the clothes processing device to continue the drying operation.

[0111] Likewise, by controlling the clothes processing device to stop the drying operation, the safety problem caused by the filter box being taken out while the drying continues is avoided, thereby improving the safety of the clothes processing device.

[0112] On the basis of the above embodiments and based on the same inventive concept, the embodiments of the present disclosure also provide a filter clogging detection device.

[0113] In some embodiments, Figure 2 This is a schematic diagram of the structure of a filter clogging detection device provided by an embodiment of the present disclosure. Figure 2 The filter clogging detection device includes: an acquisition module 21, used to obtain the number of times the drying program is run and the operating status of the fan; a prompt module 22, used to issue a first prompt message based on the number of times the drying program is run is greater than or equal to a preset number and the fan meets the preset status; wherein the first prompt message is used to prompt that the filter is clogged.

[0114] It can be understood that the filter clogging detection device provided in the embodiment of the present disclosure can implement the steps of any one of the filter clogging detection methods provided in the above-mentioned embodiments and has corresponding beneficial effects, which will not be elaborated here.

[0115] The embodiments of the present disclosure further provide a computer-readable storage medium having a computer program stored thereon, which is executed by a processor to implement the steps of any one of the filter clogging detection methods provided in the above embodiments.

[0116] On the basis of the above embodiments, the present disclosure also provides a clothes processing device. For example, Figure 3 This is a structural diagram of a clothes processing device provided by an embodiment of the present disclosure.
