[0051] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0052] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0053] Figure 1 FIG. 1 is a flow chart showing a method for detecting a filter component according to an exemplary embodiment. Figure 1As shown, the method for detecting the filter component includes steps S101 and S102.

[0054] In step S101 , the weight information of the filter component is obtained.

[0055] A filter element is a component used to filter air. For example, a filter element may be a filter in an air conditioner. Weight information is information used to represent the weight of the filter element. For example, the weight of the filter element may be detected by a sensor, and the weight information may be the output signal of the sensor (a sensor used to detect the weight of the filter element).

[0056] In step S102 , when the weight information indicates that the weight of the filter component is greater than or equal to a first weight threshold, it is determined that the filter component is blocked or pressed by foreign matter.

[0057] The first weight threshold is used to determine whether the filter element is obstructed by foreign matter or oppressed by foreign matter. In one embodiment, the first weight threshold may be preset. When the weight of the filter element is less than the first weight threshold, it can be considered that the filter element is not obstructed by foreign matter and is not oppressed. When the weight of the filter element is greater than or equal to the first weight threshold, it can be considered that the filter element is obstructed by foreign matter or oppressed.

[0058] If the filter component is blocked by foreign matter or is compressed by foreign matter, the filter component will be subjected to greater pressure. When detecting the weight of the filter component, the pressure on the filter component will also affect the detected weight of the filter component, causing the detected weight of the filter component to increase. For example, when the fan is running, due to foreign matter blocking the filter component, the pores through which air enters the air conditioner are blocked by foreign matter. Therefore, the force exerted by the air on the filter component through the foreign matter is greater, causing the detected weight of the filter component to be greater. If the weight information obtained by step S101 indicates that the weight of the filter component is greater than or equal to the first weight threshold, it is determined that the filter component is blocked or compressed by foreign matter.

[0059] Through the above technical solution, when the weight of the filter component indicated by the weight information is greater than or equal to a first weight threshold, it is determined that the filter component is blocked or compressed by a foreign object. In this way, the condition of the filter component being blocked or compressed by a foreign object can be detected. After the condition of the filter component being blocked or compressed by a foreign object is detected, the detection result can be used as a basis to guide the user to check the filter component, so that the filter component can be used correctly and thus function better.

[0060] In yet another embodiment, the filter component is disposed in an air conditioning device, and the method further comprises:

[0061] Determine the cumulative time between the shutdown time of the air conditioning equipment and the startup time of the current operation;

[0062] A first weight threshold is determined according to the accumulated time.

[0063] The air conditioning device may be a device for processing air. For example, the air conditioning device may be an air purifier or an air conditioner.

[0064] When the air conditioning equipment is shut down, the shutdown time can be recorded. When the air conditioning equipment is turned on, the startup time can be obtained. The cumulative duration can be the interval between the shutdown time of the air conditioning equipment's last run and the startup time of the current run. In other words, the cumulative duration is the length of time the air conditioning equipment has been shut down since the end of the last run. For example, if the shutdown time of the air conditioning equipment's last run is t0 and the startup time of the current run is t1, the cumulative duration is t1-t0.

[0065] When the air conditioning equipment is not in use, the filter component may gradually accumulate dust, causing the weight of the filter component to increase. During the period when the air conditioning equipment is not in use, dust that falls on the filter component may not be considered foreign matter. That is, in one embodiment, the accumulation of dust on the filter component due to the air conditioning equipment being in use may be considered normal. When determining the first weight threshold, this accumulation of dust on the filter component due to the air conditioning equipment being in use may be considered normal.

[0066] The first weight threshold may be determined based on the accumulated time. For example, considering that the longer the accumulated time, the more dust may accumulate on the filter component, the longer the accumulated time, the larger the first weight threshold may be determined.

[0067] In this embodiment, the first weight threshold is determined based on the accumulated time. This allows for more accurate determination of whether the filter element is obstructed or compressed by a foreign object, avoiding misjudging serious dust accumulation as obstruction or compression by a foreign object. Furthermore, when the accumulated time is short and dust accumulation on the filter element is mild, the first weight threshold, determined based on the accumulated time, can be prevented from being excessively high, effectively reducing the likelihood of undetected obstruction or compression by a foreign object.

[0068] In yet another embodiment, determining the first weight threshold according to the accumulated time includes:

[0069] A first weight threshold corresponding to the accumulated duration is found from a predetermined first correspondence as the determined first weight threshold. The first correspondence includes a correspondence between the accumulated duration of the air conditioning equipment and the first weight threshold.

[0070] The first correspondence may be predetermined and may represent a correspondence between the accumulated duration of the air conditioning equipment and the first weight threshold. That is, for different accumulated durations, the first weight threshold corresponding to the accumulated duration can be found from the first correspondence; and for different accumulated durations, the first weight threshold found from the first correspondence may be different.

[0071] In the process of predetermining the first correspondence, the first correspondence can be determined experimentally. For example, a filter element for use in an experiment can be preselected, installed in an air conditioning system, and the air conditioning system continuously operated. During the experiment, the weight of the filter element can be measured at predetermined intervals until the experiment is complete. In this way, the weight of the filter element after continuous use for different cumulative durations can be obtained.

[0072] A first correspondence can be predetermined based on experimental results. For example, for a certain cumulative duration, the weight of the filter component after continuous use (continuous use means the air conditioning equipment is powered on) for a period of time equal to the cumulative duration, as shown in the experimental results, is added to a preset fixed value to obtain a first weight threshold corresponding to the cumulative duration. The first weight threshold corresponding to each cumulative duration can be obtained using the above method, thereby predetermining the first correspondence.

[0073] That is to say, in one embodiment, during the execution of step S102, if the weight information indicates that the weight of the filter component is greater than or equal to the first weight threshold, then the weight of the filter component after being shut down for a cumulative period of time is at least greater than the weight of the filter component after being used continuously for a period of time equal to the cumulative period of time by a preset fixed value, then it can be considered that the filter component is blocked or compressed by foreign matter.

[0074] In this embodiment, the first corresponding relationship can be predetermined. In the process of determining the first weight threshold, the first weight threshold can be quickly determined according to the first corresponding relationship, and the response speed is fast.

[0075] In yet another embodiment, determining the first weight threshold according to the accumulated time includes:

[0076] The first weight threshold is determined according to the accumulation time and the concentration of particulate matter in the current environment.

[0077] In the process of determining the first weight threshold, the concentration of particulate matter in the current environment may also be considered. For example, the concentration of particulate matter may be the concentration of particulate matter with a particle size of less than 10 microns (PM10). Due to the different concentrations of particulate matter in the current environment, the increase in the weight of the filter component due to the continued use of the filter component may also be different. The first weight threshold may be determined based on the cumulative duration and the concentration of particulate matter in the current environment. It will be understood that, under the same cumulative duration, if the concentration of particulate matter in the current environment is greater, the determined first weight threshold may be greater.

[0078] The current ambient particulate matter concentration can be obtained using the air conditioning equipment's particulate matter sensor. In one embodiment, the particulate matter concentration can be obtained using other devices that are integrated with or interconnected to the air conditioning equipment. In other words, the air conditioning equipment can share information with other devices based on IoT technology and obtain the particulate matter concentration measured by other devices. This allows the air conditioning equipment to obtain the required particulate matter concentration without the need for a particulate matter sensor, saving space within the air conditioning equipment.

[0079] For example, the air conditioning device is an air conditioner, and the other device may be an air purifier. The other device may measure the indoor particulate matter concentration, and the air conditioning device (air conditioner) may obtain the particulate matter concentration measured by the other device (air purifier).

[0080] In one embodiment, the particulate matter concentration input by the user may also be obtained. For example, the local particulate matter concentration input by the user and obtained by the user through a network query may be obtained.

[0081] Since the particulate matter concentration is taken into account in the process of determining the first weight threshold, a lower first weight threshold can be determined when the particulate matter concentration is low. In this way, during the execution of step S102, the missed judgment of the situation where the filter component is blocked or compressed by foreign matter can be reduced; when the particulate matter concentration is high, a higher first weight threshold can be determined, which can reduce the occurrence of misjudging the weight increase of the filter component caused by natural dust accumulation as the situation where the filter component is blocked or compressed by foreign matter.

[0082] Therefore, in this embodiment, the first weight threshold is determined based on the accumulated time and the current ambient particle concentration. This takes into account not only the accumulated time but also environmental factors, thereby improving the accuracy of determining whether the filter element is blocked or compressed by foreign matter.

[0083] In yet another embodiment, determining the first weight threshold according to the accumulated time and the concentration of particulate matter in the current environment includes:

[0084] Finding a reference weight threshold value corresponding to the accumulated duration from a predetermined second correspondence relationship as the determined reference weight threshold value, wherein the second correspondence relationship includes a correspondence relationship between the accumulated duration of the air conditioning equipment and the reference weight threshold value;

[0085] Determine the reference coefficient based on the concentration of particulate matter in the current environment;

[0086] A first weight threshold is determined according to the determined reference weight threshold and the reference coefficient.

[0087] A second corresponding relationship may be predetermined, and the second corresponding relationship may represent a corresponding relationship between the accumulated time and the reference weight threshold. For different accumulated time periods, the reference weight threshold corresponding to the accumulated time period may be found from the second corresponding relationship.

[0088] The reference weight threshold can be a baseline value. For example, the reference weight threshold can be determined based on the experimental results of the above-mentioned continuous use experiment of the filter component. That is, in one embodiment, for a certain cumulative usage period, the weight of the filter component after being used for a period of time equal to the cumulative usage period is the reference weight threshold corresponding to the cumulative usage period.

[0089] The reference coefficient is a coefficient. The reference coefficient can be determined based on the concentration of particulate matter in the current environment. For example, a higher concentration of particulate matter will result in a higher reference coefficient. In one embodiment, the reference coefficient can be set between 1.5 and 2.0 based on the concentration of particulate matter.

[0090] In one embodiment, the product of the reference weight threshold and the reference coefficient may be determined as the first weight threshold.

[0091] In this embodiment, the first weight threshold is determined based on a reference coefficient determined by the particulate matter concentration and a reference weight threshold determined by the cumulative time. In this way, when determining the first weight threshold, not only the cumulative time and the particulate matter concentration are taken into consideration, making the determined first weight threshold more reasonable, but also the determination steps are simple and can be implemented quickly.

[0092] In one embodiment, in the process of determining the first weight threshold based on the cumulative time and the particulate matter concentration in the current environment, the coefficient of the cumulative time can be determined by the particulate matter concentration, and then the first weight threshold is determined by the coefficient of the cumulative time and the cumulative time.

[0093] For example, if the air quality in the space where the air conditioning equipment is located is good (such as the particulate matter concentration is less than the preset lower limit of the particulate matter concentration), when determining the first weight threshold, the coefficient of the cumulative time can be determined as 1.5, and the weight of the filter component after continuous use for 1.5 times the cumulative time (measured by the experimental method) can be determined as the first weight threshold; if the air quality in the space where the air conditioning equipment is located is poor (such as the particulate matter concentration is greater than the preset upper limit of the particulate matter concentration), when determining the first weight threshold, the coefficient of the cumulative time can be determined as 2, and the weight of the filter component after continuous use for 2 times the cumulative time (measured by the experimental method) can be determined as the first weight threshold.

[0094] In yet another embodiment, the method further comprises:

[0095] When the weight information indicates that the weight of the filter component is less than or equal to a second weight threshold, it is determined that the filter component is not installed or is not installed in place, and the second weight threshold is less than the first weight threshold.

[0096] The weight of the filter component detected by the sensor when the filter component is installed and free of dirt and blockage can be pre-detected, and the detected weight of the filter component can be determined as the second weight threshold. To avoid misjudgments, the second weight threshold can be set to a value slightly lower than the detected weight of the filter component. For example, if the weight of the filter component detected by the sensor when the filter component is installed and free of dirt and blockage is a, the second weight threshold can be set to 95% of a.

[0097] In this embodiment, when the weight information indicates that the weight of the filter component is less than or equal to the second weight threshold, it is determined that the filter component is not installed or is not installed in place. In this way, the situation that the filter component is not installed or is not installed in place can be detected, and the detection result can be used as a basis to guide the user to check the filter component, so that the filter component can be installed in place and the filter component can play a better role.

[0098] In yet another embodiment, the method further comprises:

[0099] When it is determined that the filter component is not blocked or pressed by foreign matter, the degree of dirtiness and blockage of the filter component is determined based on the weight information.

[0100] If the weight of the filter component without dirt blockage is known, the weight of the dirt blockage can be determined based on the weight information, and then the degree of dirt blockage of the filter component can be determined.

[0101] Related technologies use a photosensitive method to detect the degree of filter blockage. This method works by measuring the filter's light transmittance and determining the degree of blockage based on the transmittance. Dust accumulates on the surfaces of the light emitting and receiving devices, reducing the intensity of the emitted and received light. Consequently, over time, dust accumulates on the surfaces of the light emitting and receiving devices, reducing the accuracy of the detected filter blockage.

[0102] In this embodiment, the degree of clogging of the filter component is determined based on the weight information, so that the degree of clogging of the filter component can be accurately detected. Even if the air conditioning device has been in use for a long time, the accuracy of the detected degree of clogging of the filter component is not affected.

[0103] In yet another embodiment, determining the degree of clogging of the filter component based on the weight information includes:

[0104] Determine the weight information of the dirty blockage according to the weight information of the filter component and the net weight information of the filter component;

[0105] Determine the ratio of the weight of the dirty blockage to the net weight of the filter component based on the weight information of the dirty blockage and the net weight information;

[0106] The degree of clogging of the filter element is determined based on the ratio.

[0107] The net weight of the filter element represents the weight of the filter element without any obstruction. The obstruction weight represents the weight of the obstruction on the filter element. In one embodiment, the difference between the filter element weight and the net weight represents the obstruction weight. The ratio of the obstruction weight to the net weight of the filter element can reflect the weight of the obstruction per unit area of ​​the filter element and, therefore, the degree of obstruction of the filter element.

[0108] In the process of determining the degree of clogging of the filter component according to the ratio, one or more ratio thresholds may be preset, and the degree of clogging of the filter component may be determined by the magnitude relationship between the ratio and the preset ratio thresholds.

[0109] For example, four levels of clogging can be preset: level one, level two, level three, and level four to describe the degree of clogging of the filter component. Level one corresponds to a mild degree of clogging (few dirt clogs), while level four corresponds to a severe degree of clogging (many dirt clogs). The degree of clogging of the filter component represented by levels one to four becomes increasingly severe. Three ratio thresholds can be set for determining the degree of clogging of the filter component. For example, the three ratio thresholds can be preset as 25%, 50%, and 75%, respectively.

[0110] If the ratio of the weight of the dirt blockage to the net weight of the filter component is less than or equal to 25%, it can be determined that the degree of dirt blockage of the filter component is level one; if the ratio of the weight of the dirt blockage to the net weight of the filter component is greater than 25% and less than or equal to 50%, it can be determined that the degree of dirt blockage of the filter component is level two; if the ratio of the weight of the dirt blockage to the net weight of the filter component is greater than 50% and less than or equal to 75%, it can be determined that the degree of dirt blockage of the filter component is level three; if the ratio of the weight of the dirt blockage to the net weight of the filter component is greater than 75%, it can be determined that the degree of dirt blockage of the filter component is level four.

[0111] In one embodiment, the remaining service life of the filter component can also be determined based on the ratio of the weight of the dirt and blockage to the net weight of the filter component. For example, if the design service life of the filter component is ts, then if the ratio of the weight of the dirt and blockage to the net weight of the filter component is less than or equal to 25%, it can be determined that the remaining service life of the filter component is greater than or equal to 75% of ts; if the ratio of the weight of the dirt and blockage to the net weight of the filter component is greater than 25% and less than or equal to 50%, it can be determined that the remaining service life of the filter component is greater than or equal to 50% of ts; if the ratio of the weight of the dirt and blockage to the net weight of the filter component is greater than 50% and less than or equal to 75%, it can be determined that the remaining service life of the filter component is greater than or equal to 25% of ts; if the ratio of the weight of the dirt and blockage to the net weight of the filter component is greater than 75%, it can be determined that the remaining service life of the filter component is less than 25% of ts.

[0112] In this embodiment, the degree of clogging of the filter component is determined based on the ratio of the weight of the dirt and blockage to the net weight of the filter component. The method is simple, and the determined degree of clogging of the filter component can well reflect the actual situation of the filter component and provide a basis for the user to plan the use of the filter component.

[0113] In yet another embodiment, the filter component is disposed in an air conditioning device, and the method further comprises:

[0114] Get fan speed information in air conditioning equipment;

[0115] The net weight information is determined based on the obtained fan speed information.

[0116] The fan speed information is information representing the fan speed. Since the operation of the fan during operation of the air conditioning equipment may affect the force applied to the filter component, the net weight information can be determined based on the fan speed information.

[0117] The weight of the filter element without dirt or blockage at different fan speeds (different fan speeds) can be measured in advance through experiments to serve as the net weight of the filter element. A third correspondence can be determined based on the net weight of the filter element at the different fan speeds. The third correspondence is a correspondence between the fan speed and the net weight.

[0118] During the implementation of the detection method for the filter component provided in the present disclosure, the net weight information corresponding to the obtained fan speed information can be found from the third correspondence, and the found net weight information is determined as the net weight information of the filter component (that is, during the implementation of the detection method for the filter component provided in the present disclosure, the net weight information is used to determine the ratio of the weight of the dirt and blockage to the net weight of the filter component).

[0119] It is worth noting that, since the operation of the fan affects the force applied to the filter component, the effect of the fan operation on the force applied to the filter component can also be considered in determining the first and second weight thresholds. For example, the weight of the filter component detected by the sensor when the filter component is installed without dirt or blockage at different fan speeds can be pre-detected, and a fourth corresponding relationship can be predetermined based on the detection results. The fourth corresponding relationship is the corresponding relationship between the fan speed and the second weight threshold. Therefore, in implementing the filter component detection method provided in the present disclosure, the second weight threshold can be determined based on the fourth corresponding relationship and the fan speed.

[0120] In this embodiment, the net weight information of the filter component is determined based on the fan speed, so that the determined net weight information of the filter component takes into account the influence of the fan operation on the force of the filter component, thereby making the determined degree of dirtiness and blockage of the filter component more accurate, and being able to provide users with more accurate maintenance basis and enhance user experience.

[0121] In yet another embodiment, the method further comprises:

[0122] When the determined degree of dirtiness and blockage reaches a preset threshold number of times for the same degree of dirtiness and blockage, a prompt message is output. The prompt message is used to indicate the degree of dirtiness and blockage of the filter component. When the degree of dirtiness and blockage of the filter component reaches a predetermined condition, the prompt message is also used to prompt the replacement of the filter component.

[0123] In one embodiment, the degree of clogging of the filter component can be repeatedly detected. The number of times threshold can be preset. For example, the number of times threshold can be preset to 2 times, or for another example, the number of times threshold can be preset to 4 times. The prompt message can be text, sound, or image, and can be used to inform the user of the degree of clogging of the filter component and the remaining service life of the filter component.

[0124] For example, the filter component's clogging level can be repeatedly tested. If, out of four tests of the filter component's clogging level, all four test results are level one (the number of times the determined level of clogging is the same reaches a preset threshold), a prompt message can be output, indicating that the filter component's clogging level is level one and the filter component's remaining useful life is greater than or equal to 75% ts. For another example, if, out of five tests of the filter component's clogging level, four test results are level two and one test result is level three, a prompt message can be output, indicating that the filter component's clogging level is level two and the filter component's remaining useful life is greater than or equal to 50% ts.

[0125] Predetermined conditions for determining whether the filter component needs to be replaced can be preset. For example, the preset condition can be that the degree of dirtiness and blockage of the filter component reaches level four. That is to say, if after four tests, the test results are all level four, it can be determined that the filter component needs to be replaced. The prompt message can include content that prompts the user that the filter component needs to be replaced.

[0126] If the degree of dirtiness and blockage of the filter component does not reach a predetermined condition, the prompt message may include content prompting the user that the filter component does not need to be replaced.

[0127] In one embodiment, after the prompt message is output, the detection of the degree of dirtiness and blockage of the filter component may be terminated to save computer computing power and electrical energy.

[0128] In this embodiment, a prompt message is output when the number of times the determined level of blockage reaches a preset threshold number of times. This allows the user to be informed of the level of blockage of the filter component. Furthermore, when the level of blockage reaches a predetermined condition, the output prompt message can prompt the user to replace the filter component, thereby improving the user experience. Because the prompt message is output when the number of times the determined level of blockage reaches the preset threshold number of times, misjudgments due to accidental reasons are avoided.

[0129] In another embodiment, the weight information is a voltage signal obtained by detecting the weight of the filter component through a piezoelectric sensor.

[0130] Due to the characteristics of piezoelectric sensors, when subjected to a force within its range, it outputs a voltage corresponding to the force. The weight of the filter component can be detected by the piezoelectric sensor, and the filter weight can be represented by the voltage signal output by the piezoelectric sensor. Similarly, net weight information can also be represented by voltage.

[0131] In this embodiment, the piezoelectric sensor is used to detect the weight of the filter component, so that the accurate weight of the filter component can be obtained, reducing detection errors.
