Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of clothing processing equipment, and in particular to a control method and device for clothing processing equipment, and clothing processing equipment. Background Art

[0003] At present, when using a clothes dryer to dry clothes, the humidity is mainly used to judge whether the dryer has completed the drying operation. For example, the load humidity is detected by contacting the load through a conductivity sensor, but the conductivity sensor can only detect the humidity of the load it contacts, and cannot detect the humidity inside the load or the humidity of the load it does not contact. Therefore, the humidity detection result is not accurate enough, which can easily lead to inaccurate dryness judgment. Some dryers have humidity sensors, and dryness is judged by the humidity sensor, but the humidity sensor detects the ambient humidity in the dryer barrel. The ambient humidity in the barrel is not equal to the humidity of the load. Therefore, the humidity sensor detection result is not accurate enough, which affects the accuracy of dryness judgment.

[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. In some embodiments, the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0041] 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.
[0042] At present, when using a clothes dryer to dry clothes, the humidity is mainly used to judge whether the dryer has completed the drying operation. For example, the load humidity is detected by contacting the load through a conductivity sensor, but some loads, such as down jackets and cotton jackets, are easier to dry on the outside, while the moisture inside the load is not easy to evaporate, making it more difficult to dry. The conductivity sensor detects the humidity outside the load and cannot detect the humidity inside. Therefore, the detected humidity is inaccurate and the drying degree of the load cannot be determined; or the load is the type that needs to be dried against the wall, such as wool clothes. The conductivity sensor cannot contact the load against the wall, so it cannot accurately detect the load humidity, resulting in inaccurate dryness judgment. Some dryers have humidity sensors, and dryness is judged by the humidity sensor, but the humidity sensor detects the ambient humidity in the dryer barrel. The ambient humidity in the barrel is not equal to the humidity of the load. Therefore, the detection result of the humidity sensor is not accurate enough, affecting the accuracy of dryness judgment.
[0043] In view of the above-mentioned defects of the prior art, an embodiment of the present disclosure provides a control method for a clothing processing device. The method can be executed by a control device for a clothing processing device provided by an embodiment of the present disclosure, and the control device for the clothing processing device can be implemented in software and / or hardware. The control method for a clothing processing device provided by an embodiment of the present disclosure can be applicable to clothing processing devices of various drying types. The embodiment of the present disclosure does not limit the type of drying principle, for example, heat pump type or other types are applicable.
[0044] The control method, device and clothing processing device of the clothing processing device provided by the embodiments of the present disclosure are exemplarily described below with reference to the accompanying drawings.
[0045] Exemplarily, the clothing processing device includes a distance sensing device, and the distance sensing device is used to detect the distance to the load in the clothing processing chamber. The distance sensing device is arranged in the clothing processing device, and the distance sensing device and the load are in the same space. The distance sensing device can directly detect the distance between itself and the load in the clothing processing chamber. In some optional embodiments, the distance sensing device can be a distance sensor, such as a time-of-flight laser ranging sensor, a millimeter wave ranging sensor, or an ultrasonic ranging sensor. The embodiments of the present disclosure do not limit the specific type of the distance sensor, and the above is only used as an example.
[0046] Figure 1 A flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the control method of the clothes processing device includes S100 to S200:
[0047] S100. Obtaining the distance from the load in the laundry processing chamber detected by the distance sensing device at preset time intervals.
[0048] When a load is processed using a clothes processing device, the load is located in the clothes processing chamber, and a distance sensing device is provided in the clothes processing device. The distance sensing device can directly detect the distance between itself and the load in the clothes processing chamber. The longer the drying time, the less moisture in the load, the fluffier the load becomes, so that the volume of the load increases, and the distance between the load and the distance sensing device decreases. Therefore, the distance detected by the distance sensing device to the load in the clothes processing chamber can be obtained at preset intervals, so as to obtain the change in the distance between the load in the clothes processing chamber and the distance sensing device at different drying times.
[0049] The preset time of the interval can be set according to actual needs, and the present disclosure does not set any restrictions on this. Multiple groups of distances can be obtained at preset intervals, and the average value of the multiple groups of distances can be calculated. The average value of the multiple groups of distances can also be calculated after the abnormal values in the multiple groups of distances are eliminated. The average value of the multiple groups of distances is determined as the distance detected by the distance sensing device to the load in the clothing processing chamber to improve the accuracy and reliability of the detection.
[0050] Exemplarily, the distance sensing device may be a time-of-flight laser distance sensor. When measuring distance, the laundry processing chamber is in a stationary state, and the time-of-flight laser distance sensor emits a laser toward the position of the load. The laser contacts the load and is reflected back to the time-of-flight laser distance sensor. Therefore, the distance information of the load can be determined based on the duration of the laser return. In some embodiments, the specific position of the time-of-flight laser distance sensor and the laser emission direction of the time-of-flight laser distance sensor can be set according to actual needs, and other distance sensing devices can also be used in the embodiments of the present disclosure, and the specific implementation methods will not be described one by one.
[0051] S200: Determine that drying is finished based on the difference between the distances of two adjacent detections being less than a difference threshold.
[0052] As the moisture in the load continues to decrease, the volume of the load increases, and the distance between the load and the distance sensing device decreases, there will be a difference between the distances of two adjacent detections. As the clothing processing equipment continues to dry the load, the moisture in the load is evaporated. When it is dried to a certain degree, the moisture in the load is stable, and the volume of the load remains basically unchanged or changes slightly. Therefore, the distances of two adjacent detections are the same or similar. The difference between the distances of two adjacent detections is compared. If the difference in distance is less than the difference threshold, it can be determined that the drying is over, avoiding overdrying if the drying continues. The disclosed embodiment does not need to detect the humidity of the load, but judges the degree of drying of the load by the change in the distance between the load and the distance sensing device, thereby improving the accuracy of judging dryness.
[0053] For example, the initial distance of the load in the laundry processing chamber detected by the distance sensing device is D0, and the distance D detected by the distance sensing device to the load in the laundry processing chamber is obtained every preset time T0. n (Initial n = 1), the difference threshold is D a For example, after the first preset time T0, the distance obtained is D1, D 0- D1 is the difference between the first two adjacent detection distances. Compare D0-D1 with D a If D0-D1>D a , indicating that the load volume is still changing, and it is necessary to continue drying and detecting the distance. After the second preset time T0, the distance obtained is D2, and D1-D2 is the difference between the distances of the second two adjacent detections. Compare D1-D2 with D a If D1-D2>D a , indicating that the load volume is still changing, and it is necessary to continue drying and detecting the distance. Continue the detection calculation in this way until the nth preset time T0, and the distance obtained is D n , D n-1 -D nis the difference between the distances of the nth two adjacent detections, compare D n-1 -D n With D a If D n-1 -D n <D a , it can be determined that the load volume remains basically stable and there is no over-drying, confirming that the load drying is completed.
[0054] The present invention is provided with a distance sensing device in the clothing processing equipment. When there is a load in the clothing processing chamber, the distance sensing device can detect the distance between the load and the distance sensing device. The moisture content of the load in the clothing processing chamber is different, and the volume of the load is also different, so the distance between the load and the distance sensing device is different. As the drying time changes, the moisture in the load will gradually decrease. Therefore, the distance between the load in the clothing processing chamber detected by the distance sensing device is obtained at preset intervals, and the difference between the distances of two adjacent detections is determined until the difference between the distances of two adjacent detections is less than the difference threshold, indicating that the moisture content in the load is basically stable, and the drying can be determined to be finished. The present invention accurately judges the dryness of the load in the clothing processing chamber by detecting the distance sensing device to the load in the clothing processing chamber, avoids overdrying or uneven drying, and improves the drying effect.
[0055] In some embodiments, obtaining the distance to the load in the laundry processing chamber detected by the distance sensing device each time includes:
[0056] The distance between the distance sensing device and the load in the laundry processing chamber detected when the laundry processing chamber is in a static state is acquired.
[0057] In order to ensure that the distance information detected by the distance sensing device and the load in the clothing processing chamber is more accurate, in the embodiment of the present disclosure, the distance information between the distance sensing device and the load in the clothing processing chamber is obtained when the clothing processing chamber is in a static state. When the clothing processing chamber is in a static state, the load in the chamber remains stationary, and when the distance sensing device detects, the distance between the distance sensing device and the load remains unchanged, so the detected distance information is more accurate. If the detection is performed when the clothing processing chamber is in a rotating state, the load will flip in the clothing processing chamber, causing the distance between the distance sensing device and the load to constantly fluctuate, and it is impossible to obtain accurate and fixed distance information. Therefore, the embodiment of the present disclosure obtains the distance information between the distance sensing device and the load in the clothing processing chamber detected by the distance sensing device when the clothing processing chamber is in a static state.
[0058] In some embodiments, the stationary state may be a stop phase of the rotation rhythm of the laundry processing chamber; or a stop moment may be set for the laundry processing chamber, and the stationary state occurs at the stop moment.
[0059] Optionally, the distance information between the distance sensing device and the load in the clothing processing chamber is obtained when the distance sensing device detects the distance of the load in the clothing processing chamber during the stop phase of the rotation rhythm of the clothing processing chamber. The clothing processing chamber has a rotation rhythm during the drying load process. During the rotation phase of the rotation rhythm, the clothing processing chamber can shake out the load in the chamber to make it dry more evenly. In order to avoid the problem of excessive power or affecting the life of the clothing processing chamber due to continuous rotation of the clothing processing chamber, there will also be a stop phase in the rotation rhythm. During the stop phase, the clothing processing chamber is equivalent to a stationary state, and the load in the chamber remains stationary without flipping. When the distance sensing device detects the load distance, the distance between the distance sensing device and the load is fixed and will not change. Therefore, it is more accurate to obtain the distance information between the distance sensing device and the load in the clothing processing chamber during the stop phase of the rotation rhythm of the clothing processing chamber.
[0060] Optionally, a plurality of stop moments are set to obtain distance information between the distance sensing device and the load in the clothing processing chamber at the stop moment of the clothing processing chamber.
[0061] During the drying process of the laundry processing chamber, whenever the preset stop time is reached, the laundry processing chamber stops rotating and is in a stationary state, and the load in the chamber remains stationary and does not flip. When the distance sensing device detects the distance of the load, the distance between the distance sensing device and the load is fixed and does not change, so the distance information between the distance sensing device and the load in the laundry processing chamber is more accurate.
[0062] In some embodiments, before obtaining the distance to the load in the laundry processing chamber detected by the distance sensing device at every preset time, the method includes:
[0063] It is identified that the load in the laundry processing chamber is a first preset load type, and it is determined to operate a first laundry processing mode.
[0064] Alternatively, a first laundry processing mode selection instruction is obtained to determine to run the first laundry processing mode.
[0065] When the clothing processing device dries the load, the clothing processing chamber will rotate continuously to quickly evaporate the water in the load. If the clothing processing chamber is in a static state, the clothing processing chamber stops rotating and the load falls to the bottom of the clothing processing chamber. Loads made of easily deformed materials that fall to the bottom of the clothing processing chamber and rub against the bottom of the clothing processing chamber are easily deformed. For example, woolen clothes are easily deformed by repeatedly falling, hitting, and rubbing against the bottom of the clothing processing chamber. Therefore, considering the type of load, before obtaining the distance to the load in the clothing processing chamber detected by the distance sensing device at preset time intervals, it should be determined whether the load can run the first clothing processing mode. Among them, the first clothing processing mode is suitable for loads that are not easily deformed, and the distance sensing device detects the distance to the load in the clothing processing chamber when the clothing processing chamber is in a static state.
[0066] Whether to operate the first clothing processing mode can be determined by identifying the load in the clothing processing chamber. For example, a first preset load type can be set in advance, and the first preset load type includes a load type that is not easily deformed and preset by the user, such as a chemical fiber load, etc. In some optional embodiments, the first preset load type may also include other load types, such as those selected according to the load material. The embodiments of the present disclosure do not limit this and are only used as examples. The preset first preset load type and the first preset load type corresponding to the first clothing processing mode are stored in the memory. The clothing processing device can identify and obtain the load type in the clothing processing chamber, and determine whether it belongs to the stored first preset load type based on the determined load type. If it is determined that the load type in the clothing processing chamber is the first preset load type, it is determined to operate the first clothing processing mode.
[0067] For example, the type of load in the laundry processing chamber can be identified by an image detection device, for example, an image sensor is set in the laundry processing chamber, a load image is collected, and the type of load in the laundry processing chamber is analyzed based on the image. In some optional embodiments, other types of detection devices can also be set to detect the load type, which is not limited in the embodiments of the present disclosure and is only used as an example.
[0068] In some embodiments, a first laundry processing mode selection instruction may be obtained to determine the operation of the first laundry processing mode. For example, a first laundry processing mode button is provided on the laundry processing device, and when the user uses the laundry processing device to dry a load, the user selects to start the first laundry processing mode button according to the load type, so that the laundry processing device obtains the first laundry processing mode selection instruction and then determines to operate the first laundry processing mode.
[0069] Optionally, the clothing processing device may also obtain the first clothing processing mode selection instruction through wireless communication. For example, the clothing processing device is provided with a wireless communication module, and the user sends the first clothing processing mode selection instruction to the wireless communication module of the clothing processing device through an intelligent terminal such as a mobile phone, and the clothing processing device obtains the first clothing processing mode selection instruction, and then determines to run the first clothing processing mode. The method for obtaining the first clothing processing mode selection instruction provided in the embodiment of the present disclosure is only for illustration, and in some optional implementations, other methods may also be used, and the embodiment of the present disclosure does not limit this.
[0070] In some embodiments, based on the difference between two adjacent detected distances being less than a difference threshold, determining that drying is finished includes:
[0071] The distance threshold is determined based on the distance of the first detection.
[0072] The drying is determined to be finished when the difference between the distances of two adjacent detections is less than the difference threshold and the distance of the last detection is less than the distance threshold.
[0073] Since down jackets, cotton jackets and other non-deformable loads have fillers such as feathers, down or cotton inside, they will gradually become fluffy during the drying process. If they are over-dried, the down jackets or cotton jackets are more likely to be damaged, so over-drying should be avoided. Therefore, when drying such loads, you should ensure that the moisture content of the load meets the requirements when drying is completed, but do not over-dry to avoid damage to the load.
[0074] Based on this, a distance threshold is set in the embodiment of the present disclosure. The load in the clothing processing chamber is different, and the distance of the first detection will also be different. The distance between the load that has completed drying and the distance sensing device is also different, so there are differences in the distance threshold. The distance threshold can be determined based on the distance of the first detection, that is, based on the initial distance of the load in the clothing processing chamber detected by the distance sensing device. If the distance between the load that has completed drying and the distance sensing device (the distance detected for the last time) is less than the distance threshold, it means that the load is fluffy enough and the volume has met the requirements for the end of drying.
[0075] As the clothing processing device continues to dry the load, a large amount of water in the load is evaporated, and the volume of the load will continue to increase. Therefore, the distance between the load and the distance sensing device becomes smaller, and there is a difference in the distance between two adjacent detections. When the load is dried to a certain extent, the water content in the load is stable, the volume of the load remains basically unchanged or changes slightly, and the difference in the distance between two adjacent detections is less than the difference threshold. Therefore, the embodiment of the present disclosure determines that the drying is finished based on the difference in the distance between two adjacent detections being less than the difference threshold, and the distance of the last detection being less than the distance threshold, and the accuracy of the judgment is improved through two judgment conditions.
[0076] For example, the load placed in the clothing processing device is a down jacket, the initial distance of the load in the clothing processing chamber detected by the distance sensing device is D0, and the distance D detected by the distance sensing device to the load in the clothing processing chamber is obtained every preset time T0. n (Initial n = 1), the difference threshold is D a , the distance threshold is D b Compare the relationship between the difference between two adjacent detected distances and the difference threshold, and the relationship between the detected distance and the distance threshold, until after the nth preset time T0, the distance obtained is D n , D n-1 -D n is the difference between the distances of the nth two adjacent detections, compare D n-1 -D n With D a The relationship between D n With D b If D n-1 -D n <D a And Dn <D b , it can be determined that the load volume remains basically stable and there is no over-drying, confirming that the load drying is completed.
[0077] In some embodiments, determining the distance threshold according to the first detected distance includes:
[0078] According to the first detected distance and the corresponding relationship between the detected distance and the distance threshold, the distance threshold corresponding to the first detected distance is determined.
[0079] For example, the load in the laundry processing chamber is different, and the volume after drying is also different, so there are differences in the distance threshold. There is a corresponding relationship between the distance of the load in the laundry processing chamber detected by the distance sensing device for the first time and the distance threshold. For example, the corresponding relationship between different detection distances and distance thresholds can be obtained through multiple experiments and stored in a memory. Therefore, after obtaining the distance detected for the first time, the corresponding distance threshold can be determined according to the corresponding relationship between the detection distance and the distance threshold.
[0080] In some optional embodiments, the distance threshold corresponding to the first detected distance needs to be determined in combination with the load type. Due to different load types, the fluffiness after drying is different, so the distance between different loads and the distance sensing device after drying is also different. For example, down jackets and cotton jackets with fillings inside are more fluffi, while cotton and linen are less fluffi after drying, resulting in different distances between the load after drying and the distance sensing device. Therefore, the corresponding relationship between the detection distance and the distance threshold of the above-mentioned load types is different. When determining the distance threshold, it is also necessary to combine the load type to determine the appropriate corresponding relationship between the detection distance and the distance threshold, and then determine the distance threshold corresponding to the first detected distance.
[0081] In some optional implementations, such as load types such as cotton, linen, and chemical fibers, the fluffiness after drying is similar, and therefore the same corresponding relationship between detection distance and distance threshold can be applied.
[0082] For example, the bulkiness model of different load types (the corresponding relationship between the detection distance and the distance threshold value can be determined) can be obtained through experimental data and stored in the memory. The corresponding bulkiness model is called from the memory by obtaining the load type in the clothing processing chamber. The distance to the load in the clothing processing chamber is detected for the first time by the distance sensing device, and the distance threshold value corresponding to the first detected distance is determined in combination with the corresponding bulkiness model.
[0083] In some optional implementations, the distance threshold may be obtained by other methods, which are not limited in the present disclosure and the above is only an example.
[0084] In some embodiments, obtaining the distance to the load in the laundry processing chamber detected by the distance sensing device each time includes:
[0085] The laundry processing chamber of the laundry processing device is controlled to rotate so that the load in the laundry processing chamber rotates close to the wall, and the distance to the load in the laundry processing chamber detected by the distance sensing device is obtained.
[0086] In the disclosed embodiment, the rotation of the clothing processing chamber of the clothing processing device is controlled so that the load in the clothing processing chamber rotates close to the wall. During the rotation close to the wall, the distance to the load in the clothing processing chamber is detected by the distance sensing device. When controlling the rotation of the clothing processing chamber of the clothing processing device in the disclosed embodiment, the rotation speed of the clothing processing chamber is adjusted so that the load rotates with the clothing processing chamber and sticks to the inner wall of the clothing processing chamber, and the load does not fall to the bottom of the clothing processing chamber. During the drying process, the load continues to rotate close to the wall, which can prevent the load from falling to the bottom of the clothing processing chamber and being deformed, and the distance sensing device can detect the distance between the load and the wall.
[0087] In some embodiments, before acquiring the distance to the load in the laundry processing chamber detected by the distance sensing device at every preset time, the method further includes:
[0088] It is identified that the load in the laundry processing chamber is a second preset load type, and it is determined to operate a second laundry processing mode.
[0089] Alternatively, a second laundry processing mode selection instruction is obtained to determine to run the second laundry processing mode.
[0090] Loads that are easily deformed need to rotate against the wall during the drying process, such as woolen clothes, to prevent the load from falling to the bottom of the clothing processing chamber when the clothing processing chamber stops rotating and being deformed by the force of falling. Taking into account the difference between such loads that are easily deformed and loads that are not easily deformed, when drying loads that are easily deformed, the clothing processing chamber should continue to be in a rotating state so that the load in the clothing processing chamber rotates against the wall to prevent the load from falling. Therefore, it is necessary to determine whether the load is running the second clothing processing mode, which is suitable for loads that are easily deformed. After determining the second clothing processing mode, the clothing processing chamber of the clothing processing equipment can be controlled to rotate so that the load in the clothing processing chamber rotates against the wall, and the distance to the load in the clothing processing chamber detected by the distance sensing device can be obtained to prevent the load from deforming.
[0091] Whether to operate the second clothing processing mode can be determined by identifying the load in the clothing processing chamber. For example, a second preset load type can be pre-set, and the second preset load type includes a user-preset load type that is easy to deform, such as woolen clothes. In some optional embodiments, the second preset load type may also include other loads that are easy to deform. The embodiments of the present disclosure do not limit this and are only used as examples. The preset second preset load type and the second preset load type corresponding to the second clothing processing mode are stored in the memory. The clothing processing device can identify the load type in the clothing processing chamber, and determine whether it belongs to the stored second preset load type according to the determined load type. If it is determined that the load type in the clothing processing chamber is the second preset load type, it is determined to operate the second clothing processing mode.
[0092] For example, the type of load in the laundry processing chamber can be identified by an image detection device, for example, an image sensor is set in the laundry processing chamber, a load image is collected, and the type of load in the laundry processing chamber is analyzed based on the image. In some optional embodiments, other types of detection devices can also be set to detect the load type, which is not limited in the embodiments of the present disclosure and is only used as an example.
[0093] In some embodiments, a second laundry processing mode selection instruction may be obtained to determine the operation of the second laundry processing mode. For example, a second laundry processing mode button is provided on the laundry processing device. When the user uses the laundry processing device to dry a load, the user selects to start the second laundry processing mode button according to the load type, so that the laundry processing device obtains the second laundry processing mode selection instruction and then determines to operate the second laundry processing mode.
[0094] Optionally, the clothing processing device can also obtain the second clothing processing mode selection instruction through wireless communication. For example, the clothing processing device is provided with a wireless communication module, and the user sends the second clothing processing mode selection instruction to the wireless communication module of the clothing processing device through an intelligent terminal such as a mobile phone, and the clothing processing device obtains the second clothing processing mode selection instruction, and then determines to run the second clothing processing mode. The method for obtaining the second clothing processing mode selection instruction provided in the embodiment of the present disclosure is only for illustration, and in some optional implementations, other methods can also be used, and the embodiment of the present disclosure does not limit this.

[0116] S400, end.
[0117] When the user puts the load into the clothing treatment chamber and starts the drying process, the clothing treatment mode to be run needs to be determined according to the load type. If drying a load that is not easily deformed, such as a down jacket or a cotton jacket, the first clothing treatment mode is determined to be run; if drying a load made of wool, the second clothing treatment mode is determined to be run.
[0118] In some optional implementations, other loads that are not easily deformed or damaged determine to run the first clothing processing mode, but there is no need to execute step S313. In step S315, it is only necessary to determine whether D is satisfied. n-1 -D n <D a The remaining steps are the same as those for drying down jackets, cotton jackets and other loads that are not easily deformed. a The difference threshold D between the second laundry treatment mode and a The specific value may be different and is determined according to the actual load type.
[0119] On the basis of the above embodiments, the present disclosure also provides a control device for a clothes processing device, which can be used to execute the steps of any of the control methods for clothes processing devices in the above embodiments to achieve corresponding beneficial effects. The detection of the load weight in the clothes processing device can be understood by referring to the above, and will not be repeated here.
[0120] For example, Figure 3 Schematic diagram of the structure of a control device of a clothes processing device provided by an embodiment of the present disclosure, the clothes processing device includes a distance sensing device, the distance sensing device is used to detect the distance to the load in the clothes processing chamber; Figure 3 As shown, the control device includes: a detection module 31 and a drying determination module 32. The detection module 31 is used to obtain the distance from the load in the laundry processing chamber detected by the distance sensing device at preset intervals. The drying determination module 32 is used to determine that the drying is finished based on the difference between the distances of two adjacent detections being less than the difference threshold.
[0121] For example, Figure 4A schematic diagram of the structure of a clothes processing device provided by an embodiment of the present disclosure is shown in FIG. Figure 4 As shown, an embodiment of the present disclosure further provides a clothing processing device, comprising: a clothing processing chamber 1 and a distance sensing device 2.
[0122] The laundry processing chamber 1 is used to hold a load. The distance sensing device 2 is used to detect the distance to the load in the laundry processing chamber.
[0123] The load is located in the laundry processing chamber 1, and the distance sensing device 2 is arranged in the laundry processing device and is located in the same space as the load, so as to directly detect the distance between the load and the distance sensing device 2. For example, the distance sensing device 2 is located above the load, and the distance sensing device 2 can send a detection signal to the area where the load is located, thereby obtaining the distance of the load.
[0124] Exemplarily, the distance sensing device is a time-of-flight laser distance sensor, which is disposed in the laundry processing device, and the load is located in the laundry processing chamber. When measuring the distance, the time-of-flight laser distance sensor emits a laser to the area where the load is located, and the laser contacts the load and is reflected back to the time-of-flight laser distance sensor, and the distance of the load is determined based on the time length of the laser return.
[0125] In some embodiments, continue to refer to Figure 4 , further comprising a front support plate 3. The front support plate 3 is used to support the laundry processing chamber 1.
[0126] The distance sensing device 2 is arranged at the highest position of the front supporting plate 3 .
[0127] The clothing processing device also includes a front support plate 3, which is used to support the clothing processing chamber 1 to increase its stability. The front support plate 3 is located in front of the clothing processing chamber 1, close to the location of the chamber door. Based on the structural characteristics of the clothing processing device itself, when drying the load, the load is mostly concentrated in the front position of the clothing processing chamber 1. Therefore, in order to be able to detect the distance of the load, the distance sensing device 2 is set on the front support plate 3 to avoid the situation where there is no load at the position sensed by the distance sensing device 2. Setting the distance sensing device 2 at the highest position of the front support plate 3 can also avoid the situation where the distance sensing device 2 is too low, resulting in a situation where the load is higher than the distance sensing device 2, affecting the detection result.
[0128] In some implementations, the angle and specific setting height of the distance sensing device can be adjusted according to actual needs to increase the detection range, and the embodiments of the present disclosure are not limited to this.
[0129] In some other embodiments, other devices or other types of sensors may be used as distance sensing devices, which is not limited in the present disclosure and can be selected according to actual needs.
