Description

Technical Field

[0002] Many users have clothes processing equipment with horizontal clothes processing drums, such as drum washing machines or drum dryers, at home. Since the clothes processing drums of the aforementioned clothes processing equipment are relatively dry and closed spaces with controlled temperatures, many pets like to get into the clothes processing drums. However, since the opening of the clothes processing drums of the aforementioned clothes processing equipment is located at a relatively low position, users do not notice the pets getting into the drums when putting clothes into the drums, and directly start the clothes processing equipment, resulting in pet deaths.

[0003] In order to avoid the above problems, the related art proposes to use living things such as cats and dogs as warm-blooded animals, use temperature sensors to detect the temperature characteristics in the clothing treatment barrel, or use vibration sensors to detect the vibration characteristics of the clothing treatment barrel when it is stopped, to determine whether there are living things in it. However, the temperature detection method can only be used when there is a large temperature difference between the ambient temperature and the temperature of the living things. In hot weather conditions such as summer, the temperature of the living things is similar to the temperature of the clothing treatment barrel, and living things cannot be detected. The detection method using a vibration sensor will result in low detection accuracy due to wear and tear during long-term use of the equipment, dirt accumulation, etc. Summary of the invention

[0048] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0049] In order to solve the problem that the temperature detection method cannot be applied to the detection of living things in the clothing treatment barrel under various environmental conditions, and the problem that the temperature detection method cannot realize variable temperature living thing detection, the embodiment of the present disclosure provides a method of using distance detection to realize the detection of living things in the clothing treatment barrel.

[0050] Before analyzing the living thing detection method provided by the embodiment of the present disclosure, the clothing processing device provided by the embodiment of the present disclosure is first introduced. As analyzed in the background technology, the clothing processing device in the embodiment of the present disclosure can be a drum washing machine or a drum dryer. The following is an analysis of the common structures in the drum washing machine and the drum dryer related to the present solution.

[0051] In one embodiment, a laundry treating apparatus includes an apparatus body, a laundry treating tub, a driving motor, and a distance sensor.

[0052] The output shaft of the driving motor is connected to the input shaft of the clothes processing tub, and is used to drive the clothes processing tub to rotate relative to the device body.

[0053] In some embodiments, the distance sensor is independent of the laundry treatment tub and is a fixed position sensor. The detection end of the distance sensor faces the target position at the bottom of the laundry treatment tub, and when it is working, it can detect the distance from the detection end to the opposite object. In practical applications, the distance sensor can be an ultrasonic distance sensor, a millimeter wave distance sensor, or other sensors with similar distance detection functions. The bottom of the aforementioned laundry treatment tub refers to the area with the lowest horizontal height in the horizontal laundry treatment tub.

[0054] In practical applications, in order for the distance sensor to detect the distance to the set position at the bottom of the laundry treatment tub, the distance sensor position should be set reasonably. In some embodiments, the distance sensor can be set on the front support of the device body and irradiated into the laundry treatment tub through the clothes feeding opening of the laundry treatment tub. In other embodiments, the distance sensor can be set on the drum door of the device body, and the detection end of the distance sensor is facing the target position at the bottom of the laundry treatment tub when the drum door is closed.

[0055] In some other embodiments, the distance sensor can also be installed on the laundry treatment tub and illuminate a specific position in the laundry treatment tub. When the aforementioned specific position falls to the bottom of the laundry treatment tub, the distance sensor can illuminate the specific position and generate distance detection data.

[0056] Figure 1 FIG. 1 is a flow chart of a method for detecting living things provided by an embodiment of the present disclosure. Figure 1 As shown, the disclosed embodiment provides more living thing detection methods including S110 - S120 .

[0057] S110: Control the rotation of the laundry processing tub and obtain distance detection data generated by the distance sensor.

[0058] In the disclosed embodiment, after the user closes the drum door of the laundry processing device and controls the laundry processing device to start, the laundry processing device first controls the laundry processing tub to rotate. The aforementioned control of the laundry processing tub to rotate is to control the laundry processing tub to rotate at a relatively low speed.

[0059] While or after the laundry treatment tub is controlled to rotate, the laundry treatment device controls the distance sensor to power on and perform distance detection to generate distance detection data. At this time, the distance detection data is the distance data from the distance detection end to the object opposite to it.

[0060] In different situations, the aforementioned opposite object may be different, which may be a laundry treatment bucket, laundry to be treated, or a living thing. Therefore, correspondingly, in different situations, the distance detection data generated by the distance sensor contains different information features. It may contain information features that the laundry treatment bucket is empty, or it may contain features that the laundry treatment bucket is not empty and the type of content therein.

[0061] S120: Determine whether there is a living thing in the clothes processing tub according to the distance detection data.

[0062] After obtaining the distance detection data, the distance detection data can be processed and analyzed to mine the information features hidden in the distance detection data, and then determine whether there is a living thing in the laundry treatment barrel. How to determine whether there is a living thing in the laundry treatment barrel based on the distance detection data will be analyzed later. Here, it is only necessary to determine whether there is a living thing in the laundry treatment barrel based on the distance detection number.

[0063] The living thing detection method provided by the embodiment of the present disclosure obtains the distance detection data generated by the distance sensor after controlling the rotation of the clothing treatment barrel of the clothing treatment device, mines and analyzes the distance detection data, and determines whether there is a living thing in the clothing treatment barrel according to the implicit information of the distance detection data. Because the working characteristics of the distance sensor will not be affected by the ambient temperature, and the detection performance will not be degraded due to the long-term operation of the clothing treatment barrel, the living thing detection method provided by the embodiment of the present disclosure can realize the detection of living things at different ambient temperatures or after long-term use.

[0064] The foregoing only mentions that it is possible to determine whether there is a living thing in the laundry treatment tub based on the distance detection data. The following is an analysis of how to determine whether there is a living thing in the laundry treatment tub based on the distance detection data. In some embodiments, the aforementioned S110 controls the rotation of the laundry treatment tub and obtains the distance detection data generated by the distance sensor, including S111-S113.

[0065] S111: After controlling the laundry processing tub to rotate, the laundry processing tub is controlled to stop rotating.

[0066] In the embodiment of the present disclosure, after the clothes treating apparatus controls the clothes treating tub to rotate at a relatively low rotation speed for a relatively short period of time, the clothes treating apparatus subsequently controls the clothes treating tub to stop rotating.

[0067] S112: Acquire first distance detection data generated by the distance sensor when the laundry processing tub stops rotating.

[0068] The first distance detection data generated by the distance sensor when the laundry processing tub stops rotating is detection data determined by distance detection after the laundry processing tub stops rotating completely and the contents therein fall to the bottom area of ​​the laundry processing tub.

[0069] According to experience, when the laundry treatment tub is not empty, when the laundry treatment tub rotates, the contents therein will rotate with the rotation of the laundry treatment tub. After the laundry treatment tub stops rotating, the contents therein will fall due to gravity. By reasonably setting the rotation speed and rotation angle of the laundry treatment tub, most of the contents therein can fall to the bottom of the laundry treatment tub. Accordingly, the first distance detection data generated by the distance sensor when the laundry treatment tub stops rotating is the distance from the surface of the contents irradiated by the distance sensor to the distance sensor.

[0070] In practical applications, due to the influence of various random factors (such as temperature), the first distance detection data generated by the distance sensor may have a large error with the actual distance. To solve this problem, obtaining the aforementioned first distance detection data may include obtaining multiple stop distance detection data generated by the distance sensor when the laundry treatment tub stops, and then calculating the average of the multiple stop distance detection data as the first distance detection data.

[0071] S113: After a preset time period, second distance detection data generated by the distance sensor is obtained.

[0072] After performing distance detection to generate first distance detection data for a set period of time, the laundry processing device continues to control the distance sensor to perform distance detection to generate second distance detection data.

[0073] Depending on the type of content in the laundry treatment tub, the second distance detection data may have a different relationship to the first distance detection data.

[0074] When the content of the clothes treatment tub is only the load to be treated, the load to be treated falls after the clothes treatment stops, and its position basically does not change, and the second distance detection data is basically the same as the first distance detection data.

[0075] In the case where the contents of the laundry treatment tub include living things, the living things will be frightened and move when the laundry treatment tub rotates. Even if the laundry treatment tub stops, the living things will still move because of fright or the need to turn over. In the case of a large living thing, after a preset time, the second distance detection data generated by the distance sensor for distance detection is likely to be different from the aforementioned first distance detection data. It should be noted that the aforementioned preset time is a shorter time, and the size of the preset time can be determined based on empirical tests.

[0076] Because the types of contents in the laundry treatment tub are different, the aforementioned first distance detection data and second distance detection data can obtain different implicit information, so it can be determined whether there is a living thing in the laundry treatment tub according to the first distance detection data and the second distance detection data. Accordingly, the aforementioned S120 may include S121.

[0077] S121: Determine whether there is a living thing in the clothes processing tub according to the first distance detection data and the second distance detection data.

[0078] Determining whether there is a living thing in the laundry processing tub according to the first distance detection data and the second distance detection data is to compare the first distance detection data and the second distance detection data and determine whether there is a living thing in the laundry processing tub according to the difference characteristics therebetween.

[0079] In a specific embodiment, the aforementioned S121 includes S1211 - S1212 .

[0080] S1211: Calculate a first distance difference between the first distance detection data and the second distance detection data.

[0081] S1212: When the first distance difference is greater than the first difference, it is determined that there is a living thing in the clothes processing tub.

[0082] As analyzed above, if the contents of the laundry treatment tub include living things, the living things' activities will cause a large difference between the first distance detection data and the second distance detection data, so the first distance difference obtained by subtracting the two will be large. If the first distance difference is greater than the second difference, it is likely that there is a living thing in the laundry treatment tub.

[0083] In actual applications, although there are living things in the laundry treatment tub, due to random factors, the first distance detection data and the second distance detection data may be not much different, and then the first distance difference value is smaller than the first difference value. In this case, although there are living things in the laundry treatment tub, it is still determined that there are no living things in the laundry treatment tub. To avoid this problem, the aforementioned S113 acquiring the second distance detection data generated by the distance sensor can be: acquiring multiple second distance detection data generated by the distance sensor at intervals within a set time period.

[0084] The corresponding step S1211 of calculating the first distance difference between the first distance detection data and the second distance detection data is specifically: respectively calculating the first distance difference between each second distance detection data and the first distance detection data. The step 1212 can be: when any first distance difference is greater than the first difference, determining that there is a living thing in the laundry treatment tub.

[0085] By adopting the above method, after a preset period of time, the second distance detection data generated by the distance creation is obtained at intervals within a set time period, and the second distance detection data is compared with the first detection data to determine the first distance difference. When any first distance difference is greater than the first difference, it is determined that there is a living thing in the clothing treatment barrel, which can avoid the problem of living things not being detected in the clothing treatment barrel due to randomness.

[0086] Of course, in actual applications, the above method may result in a situation where there is only a load to be processed and no living things in the laundry treatment tub, but it is still determined that there are living things in the laundry treatment tub, that is, a false judgment. However, considering that the above false judgment can avoid the problem of living things in the laundry treatment tub but not being detected, the above error can be tolerated.

[0087] In the disclosed embodiment, after determining that there are living things in the clothing treatment tub, the clothing treatment device can suspend operation and output a prompt message that there may be living things in the clothing treatment tub to prompt the user to check the clothing treatment tub to confirm whether there are indeed living things in it.

[0088] Figure 2 FIG. 1 is a flow chart of a method for detecting living things provided by another embodiment of the present disclosure. Figure 2 As shown, in another embodiment, the living thing detection method includes S210-S260.

[0089] S210: Control the laundry processing tub to rotate, and periodically obtain third distance detection data generated by the distance sensor.

[0090] S220: Determine whether the laundry processing tub is empty based on the third distance detection data; if not, execute S230; if so, execute S260.

[0091] In the disclosed embodiment, during the process of the clothes processing device controlling the clothes processing barrel to rotate, the clothes processing device controls the distance sensor to perform periodic distance detection to obtain a plurality of third distance detection data.

[0092] After obtaining a plurality of third distance detection data, the clothing processing device can analyze the plurality of third distance detection data to determine whether the clothing processing barrel is an empty barrel. If it is determined that the clothing processing barrel is an empty barrel, there is no need to compare and perform corresponding operation processing, and S260 can be directly executed to stop the operation. If it is determined that the clothing processing barrel is not an empty barrel, that is, there are contents in the clothing processing barrel, the following S230-S250 can be executed to further determine whether there are living things in it.

[0093] In a specific implementation, the above-mentioned determining whether the laundry processing tub is empty according to the third distance detection data may include S221-S224.

[0094] S221: Calculate the mean of the third distance detection data, and calculate the second distance difference between the mean and the standard distance.

[0095] In order to meet the needs of clothing treatment (specifically to achieve the needs of clothing lifting and water permeability), structures such as through holes, lifting straps, and reinforcing ribs are set on the surface of the clothing treatment barrel. In addition, the distance sensor itself will also have a certain error in distance detection. The above factors are combined. When the clothing treatment barrel is empty, there will be a certain difference between the mean calculated based on the third distance data and the standard distance determined in the previous test, but this difference will not be too large (that is, the difference in the second distance will not be too large).

[0096] Accordingly, when the laundry treatment tub is not empty, the third distance detection data determined by the above method may change due to the influence of the load therein. Moreover, when the laundry treatment tub is not empty, the mean value determined by the third detection amount data should be less than the standard distance, and the difference should be larger (even if the second distance difference is larger).

[0097] S222: Determine whether the second distance difference is less than or equal to the second difference; if so, execute S223; if not, execute S224.

[0098] S223: Determine whether the laundry processing tub is empty.

[0099] S224: Determine whether the laundry treatment tub is not empty.

[0100] As analyzed above, in the embodiment of the present disclosure, when the second distance difference is greater than the second difference, it is determined that the laundry processing tub is not empty.

[0101] In some embodiments, determining whether the laundry treatment tub is empty based on the third distance detection data may further include the following S225-S226.

[0102] S225: Calculate the mean square error of the third distance detection data, and calculate the mean square error difference between the mean square error and the standard mean square error.

[0103] S226: When the mean square error difference is greater than the third difference, it is determined that the laundry treatment tub is not an empty tub.

[0104] When the laundry treatment barrel is empty, the third distance data detected by the distance sensor will only change due to the influence of the surface structure of the laundry treatment barrel, and the mean square error determined by the corresponding third distance detection data will not be too large in the corresponding case. If the laundry treatment barrel is not empty, the mean square error determined by the third distance detection data will be larger due to the influence of the contents therein. Based on this, after calculating the mean square error difference between the mean square error of the third distance detection data and the standard mean square error, when the mean square error difference is greater than the third difference, it is determined that the laundry treatment barrel is not empty.

[0105] S230: Controlling the laundry processing tub to stop, and acquiring first distance detection data generated by the distance sensor when the laundry processing tub stops.

[0106] S240: After a preset time period, second distance detection data generated by the distance sensor is obtained.

[0107] S250: Determine whether there is a living thing in the clothes processing tub according to the first distance detection data and the second distance detection data.

[0108] The execution process of S230-250 is the same as that of the previous implementation, which will not be repeated here. For details, please refer to the previous description.

[0109] S260: Stop detection.

[0110] By using the living thing detection method provided in the embodiment of the present disclosure, firstly, it is determined whether the clothing treatment barrel is empty based on the third distance detection data detected during the rotation of the clothing treatment barrel. If it is determined that it is not empty, it is then detected whether there are living things in it, thereby avoiding the problem of false alarm of the presence of living things in the empty barrel.

[0111] In addition to providing the aforementioned living thing detection method, the embodiment of the present disclosure also provides a living thing detection device. Figure 3 Schematic diagram of the structure of the living thing detection device provided by the embodiment of the present disclosure. Figure 3 As shown, the living thing detection device 300 includes a control unit 301 and a data analysis unit 302 .

[0112] The control unit 301 is used to control the rotation of the laundry treatment tub and obtain distance detection data generated by the distance sensor.

[0113] The data analysis unit 302 is used to determine whether there is a living thing in the clothes processing tub according to the distance detection data.

[0114] In some embodiments, the control unit 301 controls the laundry treatment tub to stop rotating after controlling the laundry treatment tub to rotate, controls the acquisition of first distance detection data generated by the distance sensor when the laundry treatment tub stops rotating, and acquires second distance detection data generated by the distance sensor after a preset time. The data analysis unit 302 determines whether there is a living thing in the laundry treatment tub based on the first distance detection data and the second distance detection data.

[0115] In some embodiments, the data analysis unit 302 calculates a first distance difference between the first distance detection data and the second distance detection data; and when the first distance difference is greater than the first difference, it is determined that there is a living thing in the laundry treatment tub.

[0116] In some embodiments, the control unit 301 obtains a plurality of second distance detection data generated by the distance sensor at intervals within a set period of time. Correspondingly, the data analysis unit 302 calculates the first distance difference between each second distance detection data and the first distance detection data, and determines that there is a living thing in the laundry treatment barrel when any first distance difference is greater than the first difference.

[0117] In some embodiments, the control unit 301 obtains a plurality of stop distance detection data generated by the distance sensor when the laundry processing tub stops rotating; and obtains an average of the plurality of stop distance detection data as the first distance detection data.

[0118] In some embodiments, the control unit 301 periodically acquires the third distance detection data generated by the distance sensor during the process of controlling the rotation of the laundry treatment tub; the data analysis unit 302302 determines whether the laundry treatment tub is empty according to the third distance detection data. When it is determined that the laundry treatment tub is empty, the control unit 301 controls the acquisition of the first distance detection data generated by the distance sensor when the laundry treatment tub stops rotating.

[0119] In some embodiments, the data analysis unit 302 calculates the mean of the third distance detection data, calculates a second distance difference between the mean and the standard distance, and determines that the laundry treatment tub is not empty when the second distance difference is greater than the second difference.

[0120] In some embodiments, the data analysis unit 302 further calculates the mean square error of the third distance detection data, and calculates the mean square error difference between the mean square error and the standard mean square error; when the mean square error difference is greater than the third difference, it is determined that the laundry treatment barrel is not empty.

[0121] In some embodiments, after controlling the clothes treatment tub to stop rotating, the control unit 301 also acquires vibration characteristic data generated by the vibration sensor, where the vibration characteristic data is data determined by the vibration sensor collecting the vibration characteristics of the clothes treatment tub. The data analysis unit 302 determines whether there is a living thing in the clothes treatment tub according to the vibration characteristic data.

[0122] In some embodiments, the data analysis unit 302 extracts features from the vibration feature data to obtain a detected vibration frequency; when the detected vibration frequency meets a typical vibration frequency, it is determined that there is a living thing in the clothing treatment barrel, where the typical vibration frequency is a vibration frequency determined by vibration detection using a typical living thing.

[0123] In addition to providing the aforementioned living thing detection method and detection device, the embodiments of the present disclosure also provide a clothing processing device. Figure 4 Schematic diagram of the structure of the clothes processing device provided by the present disclosure. Figure 4 As shown, the clothing treatment device includes a controller 401, a clothing treatment barrel 402, a driving motor 403 and a distance sensor 404. The driving motor 403 drives the clothing treatment barrel 402 to rotate, and the detection end of the distance sensor 404 faces the target position at the bottom of the clothing treatment barrel 402, which is used to generate distance detection data. The controller 401 is used to control the driving motor 403 and the distance sensor 404 according to the above living thing detection method, and determine whether there is a living thing in the clothing treatment barrel 402 according to the distance detection data generated by the distance sensor 404.

[0124] In a specific implementation, the controller 401 may be a central processing unit (CPU) or other forms of processing units having data processing capabilities and / or instruction execution capabilities, and may control other components in the clothing processing apparatus to perform desired functions.

[0125] The embodiment of the present disclosure also provides a storage medium, the storage medium stores a program or instruction, the program or instruction enables a computer to execute any of the living thing detection methods provided by the embodiment of the present disclosure.
