The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and to provide a control method for a clothes drying apparatus that can effectively avoid the user from misusing a drying drum.
Example one
The embodiment mainly provides a control method of a drying clothes drying device, which detects humidity information of clothes through a humidity sensor to deduce a theoretical clothes processing program and effectively prevents a user from misusing a drying drum.
Specifically, as shown in fig. 1, the present embodiment provides a control method of a drying apparatus for drying clothes, comprising: the clothes drying equipment is a washing and drying combined machine or a clothes dryer, the washing and drying combined machine or the clothes dryer is provided with a drying drum for containing clothes to be processed, a user puts the clothes to be processed into the drying drum, selects a processing program, obtains humidity information of the clothes to be processed in the drying drum, deduces a theoretical clothes processing program according to the obtained humidity information of the clothes to be processed in the drying drum, judges whether the theoretical clothes processing program is consistent with an actual clothes processing program selected by the user, and if so, normally executes the program selected by the user; if not, prompting the user.
Further, as shown in fig. 2, a humidity sensor is disposed in the drying drum, and the humidity sensor detects a humidity value of the laundry to be processed put into the drying drum by the user and feeds the detected humidity value back to the control system. Comparing the detected humidity value of the clothes with a standard humidity value, wherein the standard humidity value is the water content of the common unwashed clothes, and when the humidity value of the clothes to be processed is detected to be smaller than the standard humidity value, the clothes to be processed is inferred to be dry clothes, and a theoretical clothes processing program is further inferred; when the humidity value of the clothes to be treated is detected to be larger than the standard humidity value, the clothes to be treated is judged to be wet clothes, and the program selected by the user is directly executed. The humidity value of the clothes is directly acquired through the humidity sensor, the efficiency is higher, and the accuracy is higher.
Further, when the clothes to be treated are judged to be dry clothes, the humidity sensor detects humidity values of different parts of the clothes, whether the humidity difference values of the different parts of the clothes to be treated are larger than a standard humidity difference value or not is judged and analyzed, if yes, the clothes are judged to contain the laundry detergent, the theoretical clothes treatment program is judged to be a washing program, and a user is prompted. If the laundry detergent exists on the clothes, the overall humidity uniformity of the clothes is inconsistent, the humidity value of the part of the clothes stained with the laundry detergent is higher, and the humidity value of the part without the laundry detergent is small, so that the humidity difference value of the part stained with the laundry detergent and the part without the laundry detergent is higher in the detection process. The method can judge whether the clothes contain the laundry detergent or not by analyzing whether the humidity difference value of different parts of the clothes to be processed is larger than the standard humidity difference value or not, can conclude that the clothes contain the laundry detergent when the humidity difference value is detected to be larger than the standard humidity difference value, and can conclude that a user wants to execute a washing program, namely the theoretical clothes processing program is the washing program, and can remind the user through voice, light flicker and other modes.
When the clothes to be treated are judged to be dry clothes, a condition that the laundry liquid is rubbed away by the clothes after the humidity sensor is stained with the laundry liquid on the clothes when the drying drum rotates exists if the laundry liquid is contained in the clothes, and thus, the humidity difference value detected by the humidity sensor is larger than the standard difference value. When the humidity difference values detected several times are all larger than the standard difference value, the laundry liquid contained in the clothes can be judged, the intention execution program of the user is deduced to be the washing program, the user is reminded in time, the user is helped to correct errors, and unnecessary accidents are avoided.
Furthermore, the humidity values of different parts of the clothes collected by the humidity sensor are respectively A1, A2, A3 and An, wherein n is more than or equal to 10; calculating to obtain An average humidity value A ═ (A1+ A2+ A3+, An)/n of the clothes, and further calculating to obtain An average humidity difference B ═ (Sigma | An-A' |)/n of the clothes, wherein An is a variable;
comparing and analyzing whether the average humidity difference B' of the clothes is greater than the standard humidity difference B or not; if yes, judging that the clothes contain the laundry detergent, deducing that the theoretical clothes processing program is a washing program, and prompting a user; if not, the program selected by the user is normally executed.
In a scheme, when the clothes to be treated are dry clothes, the drying drum is controlled to rotate at a low speed, in the rotating process of the drying drum, the humidity sensor is controlled to detect the humidity value of the clothes once every t1 time interval, and the humidity value is detected once every certain time interval, so that the detection accuracy is improved, the humidity values of the same local parts of the clothes are prevented from being detected for many times, the detected humidity difference value of the clothes is far smaller than the humidity difference value of different parts of the normally detected clothes, and the phenomenon of misjudgment is caused.
Preferably, the time of one rotation of the drying drum is set as a period T, the number of times of detection of the humidity sensor is n, wherein n is equal to or more than 10, the humidity sensor is controlled to detect once every time T1, which is equal to T/n, the humidity sensor can detect the whole circumferential direction of the clothes at uniform intervals, and the accuracy of humidity difference measurement is ensured to the maximum extent.
In another scheme, a plurality of humidity sensors are arranged at different positions in the drying cylinder, when the clothes to be treated are judged to be dry clothes, the humidity sensors simultaneously detect the humidity values of different parts of the clothes, judge and analyze whether the humidity difference values of the different parts of the clothes are greater than a standard humidity difference value, if so, judge that the clothes contain laundry detergent, judge that a theoretical clothes treatment program is a washing program, and prompt a user.
Furthermore, the humidity values of different parts of the clothes collected by the humidity sensor are respectively A1, A2, A3 and An, wherein n is more than or equal to 10, the humidity difference values of A2, A3 and An compared with A1 are respectively calculated and are respectively compared with the standard humidity difference value;
and calculating the probability P that the humidity difference value of different parts of the clothes is greater than the standard humidity difference value, judging whether the probability P is greater than the set probability P0, and if so, prompting a user.
Further, if it is inferred that the theoretical laundry processing program is not consistent with the program selected by the user, the voice prompts the user that the currently executed program is the non-washing program, for example, prompts the user that the currently executed program is a sterilization/refreshing/deodorizing or drying program, and prompts the user whether to confirm the execution of the current program, and if it is detected that the user inputs an "acknowledgement" signal to the control system or waits for t0 for the user to still not respond, the program selected by the user is normally executed.
Further, when the clothes to be processed are judged to be dry clothes, detecting a program selected by the user, and if the program selected by the user is detected to be a sterilization/refreshing/odor removal program, normally executing the program selected by the user; if the program selected by the user is detected to be the drying program and the selected heating time is more than the set time t0, the user is prompted. When a user puts clothes into the drying drum and selects a longer heating time, the clothes fibers are damaged, safety accidents are easy to cause, the user is reminded in time at the moment, and unnecessary loss is avoided.
The present embodiment further provides a drying and drying apparatus having the above control method, including: a humidity acquisition unit for acquiring humidity information of laundry to be treated; and the control unit compares and analyzes the acquired clothes humidity information and the standard humidity information stored by the server, and controls the working state of the clothes drying equipment according to the analysis result.
When the clothes drying equipment is a washing and drying combined machine, an upper cylinder of the washing and drying combined machine is a drying cylinder, a lower cylinder of the washing and drying combined machine is a washing cylinder, the upper cylinder is used for drying, sterilizing, removing peculiar smell and the like of clothes, and the lower cylinder is used for washing the clothes; if the control unit of the washing and drying combination machine detects that the laundry contains laundry detergent on the laundry, and the theoretical laundry processing program is not consistent with the program selected by the user, the control unit prompts the user that the currently executed program is a non-washing program by voice, for example, prompts the user that the currently executed program is a sterilization/refreshment/deodorization or drying program, if the washing program is to be performed, please move the laundry to a lower drum (i.e., a washing drum) and prompt the user whether to confirm to execute the current program, and if the control unit detects that the user inputs an "confirm" signal to the control system or waits for t0 time, the control unit executes the program normally according to the program selected by the user.
When the clothes drying device is a clothes dryer, the drying drum is arranged in the clothes dryer, and a control unit of the clothes dryer prompts a user that a currently executed program is a non-washing program by voice according to a detection result of a humidity sensor, for example, prompts the user that the currently executed program is a sterilization/refresh/odor removal or drying program if the laundry detergent is detected to be contained in the clothes to be processed and the program selected by the user is not consistent, and prompts the user whether to confirm to execute the current program, and if the user is detected to input a confirmation signal to a control system or the user still has no response when waiting for t0, the program is normally executed according to the program selected by the user.
According to the control method of the clothes drying equipment, the humidity sensor is used for detecting whether clothes to be dried or wet and detecting the humidity values of different parts of the clothes, whether the humidity difference values of the different parts of the clothes are larger than the standard humidity difference value or not is judged and analyzed, if yes, the clothes are judged to contain laundry detergent, a theoretical clothes treatment program is deduced to be a washing program, a user is prompted in time, the phenomenon that the user mistakenly uses a drying drum as a washing drum is avoided, resource waste caused by idle work is effectively prevented, the user is helped to correct errors in time, and safety accidents are avoided.
Example two
In the control method provided in the first embodiment, whether laundry powder is contained in the clothes or not cannot be effectively judged through the humidity sensor, and the condition that a user puts the laundry powder is difficult to judge. Therefore, the present embodiment provides a control method for a clothes drying apparatus, which can effectively infer whether laundry powder or laundry detergent is contained in the clothes by a clothes image recognition method, and further infer a theoretical clothes processing procedure.
Specifically, as shown in fig. 3 and 4, a drying drum for containing clothes to be processed is arranged in the clothes drying device, an image acquisition module is arranged in the drying drum, the image acquisition module acquires image information of the clothes to be processed in the drying drum and feeds the image information back to the control unit, the control unit deduces a theoretical clothes processing program according to the acquired image information of the clothes, and judges whether the theoretical clothes processing program is consistent with an actual clothes processing program selected by a user, if so, the program selected by the user is normally executed; if not, prompting the user.
Furthermore, an image acquisition module is arranged in the drying cylinder, the image acquisition module acquires images of clothes put into the drying cylinder by a user, and the control unit compares the acquired clothes image information with dry/wet clothes image information stored by the server; if the clothes are determined to be dry, further determining the picture details of the clothes, and performing image comparison again: if the washing powder/laundry detergent exists, the theoretical clothes treatment program is inferred to be a washing program, and a user is prompted; if no washing powder/liquid is present, the theoretical laundry treatment program is concluded to be a non-washing program.
Further, the control unit compares the clothes image information acquired by the image acquisition module with the clothes image information stored in advance, and analyzes the difference between the clothes image information and the clothes image information, wherein the clothes image information stored in advance is a reference image used for reflecting the dryness and wetness degree of the object to be dried; determining whether the laundry to be treated is dry laundry or wet laundry based on the difference;
wherein the differences comprise: a volume change of the laundry to be treated; preferably, the difference further includes a shade change of the color of the laundry. For the clothes, when the humidity of the clothes is relatively high (greater than a certain threshold), the volume of the clothes is relatively large, that is, the humidity is relatively high, the volume is relatively large, at this time, the volume of the clothes and the volume of the clothes when the clothes are dried (the humidity is lower than the certain threshold) can be used for comparing, and when the volume difference between the two volumes is relatively large, the clothes is determined to be further required to be dried. For another example, the clothes are different in color depth with and without water, and thus, the dry and wet states of the clothes currently to be treated can be determined using the difference in lightness of color.
Further, when the clothes to be processed are judged to be clothes, detailed image information of the clothes to be processed is further analyzed, if more fine particles are detected to exist in the clothes, the fact that the drying cylinder contains washing powder is determined, the drying cylinder is controlled to rotate at a low speed, meanwhile, the fan is controlled to start to blow natural air into the drying cylinder, and the washing powder is all blown into a thread scraps filter at the bottom of the drying cylinder.
Preferably, when the washing powder is determined to be contained in the drying cylinder, the drying cylinder is driven to rotate in a positive and negative alternating mode, and the clothes are shaken and scattered. The washing powder on the clothes can be better shaken off through the forward and reverse rotation of the drying cylinder, so that the washing powder on the clothes can be conveniently removed.
Further, when the clothes to be processed are judged to be dry clothes, the image information of the clothes to be processed is further analyzed, if the color depth of a plurality of positions of the clothes is detected to be inconsistent, the clothes washing liquid in the drying drum is determined, the theoretical clothes processing program is judged to be a washing program, and a user is prompted. If the user puts the laundry detergent into the drying drum, the laundry detergent falling on the clothes can partially wet the clothes, the color is darker, the clothes are relatively lighter in places without the laundry detergent, whether the laundry detergent is contained in the clothes to be processed or not can be deduced by analyzing the color information of the clothes image, if the laundry detergent exists, the intention execution program of the user can be deduced to be a washing program, and the user is reminded in time.
Further, the image acquisition module acquires image information of clothes to be processed put into the drying drum by a user, the control unit compares the acquired image information of the clothes with dry/wet clothes image information stored by the server, and if the clothes are determined to be wet clothes, the control unit executes the program normally according to the program selected by the user. When the clothes are determined to be wet clothes, no judgment is needed, because the user cannot wash the wet clothes, and the program selected by the user is normally executed.
In the control method of the clothes drying equipment provided by the embodiment, the image information of the clothes to be processed is acquired through the image acquisition module, the acquired image information of the clothes to be processed and the clothes image stored in the service area are compared and analyzed, when the existence of washing powder or laundry detergent is detected, a theoretical clothes processing program is deduced to be a washing program, and a user is timely reminded, so that the resource waste caused by useless work is effectively prevented, the user is timely helped to correct errors, and safety accidents are avoided.
The control method provided by this embodiment is further combined with the humidity detection method in the first embodiment on the basis of the aforementioned image recognition to infer whether the theoretical laundry processing procedure of the user is consistent with the laundry processing procedure selected by the user, so that the inference result is more accurate.
Specifically, a humidity sensor is further arranged in the drying drum, when the humidity sensor detects that the humidity value of the clothes is greater than a standard humidity value, the clothes to be processed is inferred to be wet clothes, and a program selected by a user is directly executed; when the humidity value of the clothes is detected to be smaller than the standard humidity value, the clothes to be processed is inferred to be dry clothes, and a theoretical clothes processing program is further inferred;
wherein the standard humidity value is the water content of the ordinary unwashed laundry.
Further, when the clothes to be processed are judged to be dry clothes, the drying drum is controlled to rotate at a low speed, the humidity sensors detect the humidity values of different parts of the clothes, whether the humidity difference values of the different parts of the clothes are larger than a standard difference value or not is judged and analyzed, if yes, the clothes are judged to contain laundry detergent, the theoretical clothes processing program is judged to be a washing program, and a user is prompted; if not, the program selected by the user is normally executed. Specifically, how to calculate the humidity difference and how to judge whether the laundry detergent is contained in the laundry to be treated according to the humidity difference are the same as those in the first embodiment, and the description thereof is omitted here.
Further, when the theoretical clothes processing program is judged to be inconsistent with the program selected by the user, the voice prompts the user that the currently executed program is the non-washing program and prompts the user whether to confirm the execution of the current program, and if the user inputs a confirmation signal to the control system or the user does not respond within the time of waiting t1, the program is normally executed according to the program selected by the user.
According to the control method of the clothes drying equipment, the clothes to be processed are judged and analyzed to be dry clothes or wet clothes in a mode of combining the image acquisition module and the humidity sensor, the humidity values of different parts of the clothes are detected, whether the humidity difference values of the different parts of the clothes are larger than the standard humidity difference value or not is judged and analyzed, if yes, the clothes are judged to contain the laundry detergent, the theoretical clothes processing procedure is deduced to be a washing procedure, the user is prompted in time, the phenomenon that the user mistakenly takes the drying drum as the washing drum is avoided, and the method is more efficient.
Another object of the present embodiment is also to provide a drying laundry drying apparatus having the above control method, the drying laundry drying apparatus being a washing and drying combined machine or a clothes dryer, comprising:
the image acquisition unit is used for acquiring image information of the clothes to be treated;
and the control unit compares and analyzes the clothes image information acquired by the image acquisition unit and the image information stored by the server, and controls the working state of the clothes drying equipment according to the analysis result.
