The invention aims to overcome the defects of the prior art and provide a control method of clothes drying equipment capable of effectively avoiding misuse of a drying drum by a user.
Example 1
The embodiment mainly provides a control method for a clothes drying device, which is used for deducing a theoretical clothes treatment program by detecting the humidity information of clothes through a humidity sensor and effectively avoiding misuse of a drying drum by a user.
Specifically, as shown in fig. 1, the present embodiment provides a control method of a clothes drying apparatus: the clothes treatment 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 cylinder for containing clothes to be treated, a user puts the clothes to be treated into the drying cylinder, selects a treatment program, acquires humidity information of the clothes to be treated in the drying cylinder, deduces a theoretical clothes treatment program according to the acquired humidity information of the clothes to be treated in the drying cylinder, judges whether the theoretical clothes treatment program is consistent with an actual clothes treatment program selected by the user, and normally executes the program selected by the user if the theoretical clothes treatment program is consistent with the actual clothes treatment 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 the humidity value of the laundry to be processed put into the drying drum by the user and feeds back the humidity value 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 common unwashed clothes, and when the detected humidity value of the clothes to be treated is smaller than the standard humidity value, deducing that the clothes to be treated are dry clothes, and further deducing a theoretical clothes treatment program; and when the humidity value of the clothes to be processed is detected to be larger than the standard humidity value, deducing that the clothes to be processed are wet clothes, and directly executing a program selected by a user. The humidity value of the clothes is directly obtained through the humidity sensor, so that the efficiency is higher and the clothes are more accurate.
Further, when it is inferred that the laundry is dry, the humidity sensor detects humidity values of different parts of the laundry, judges and analyzes whether the humidity difference of the different parts of the laundry is greater than a standard humidity difference, if so, judges that the laundry contains laundry detergent, infers that the theoretical laundry treatment program is a washing program, and prompts a user. If the laundry detergent is arranged on the clothes, the overall humidity uniformity of the clothes is inconsistent, the humidity value of the part, which is stained with the laundry detergent, of the clothes is higher, and the humidity value of the part, which is not stained with the laundry detergent, is smaller, so that the humidity difference value between the part, which is stained with the laundry detergent, and the part, which is not stained with the laundry detergent, is higher in the detection process. Whether the laundry liquid is contained in the laundry or not can be judged by analyzing whether the humidity difference value of different parts of the laundry to be treated is larger than the standard humidity difference value, and when the humidity difference value is detected to be larger than the standard difference value, the laundry liquid is deduced to be contained in the laundry, so that the user can be deduced to execute a washing program, namely, the theoretical laundry treatment program is the washing program, and the user can be reminded through voice, lamplight flickering and other modes.
When it is inferred that the laundry to be treated is dry, there is also a case that if the laundry contains laundry detergent, when the drying drum rotates, there is a case that the laundry detergent is rubbed off by the laundry after the humidity sensor is stained with the laundry detergent on the laundry, and thus, the humidity difference detected by the humidity sensor is greater than the standard difference. When the detected humidity differences are all larger than the standard differences, the laundry detergent is judged to be contained on the clothes, the user is deduced to intend to execute the program as a washing program, the user is reminded in time, the user is helped to correct errors, and unnecessary accidents are avoided.
Further, 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 value B ' = (Σ|an-A ' |)/n of the clothes, wherein An is a variable;
comparing and analyzing whether the average humidity difference B' of the clothes is larger than the standard humidity difference B; if yes, judging that the clothes contain laundry detergent, deducing that a theoretical clothes treatment program is a washing program, and prompting a user; if not, the program selected by the user is normally executed.
In one scheme, when the clothes to be treated are inferred to be dry, the drying cylinder is controlled to rotate at a low speed, in the process of rotating the drying cylinder, the humidity value of the clothes is detected once at intervals of t1 time by the control humidity sensor, and the detection is carried out once at intervals of a certain time, so that the detection accuracy is improved, the phenomenon that the humidity difference value of the detected clothes is far smaller than that of different parts of the normally detected clothes due to the fact that the humidity value of the detected clothes is the same local humidity value of the clothes for multiple times is avoided, and misjudgment is caused.
Preferably, the time of one circle of rotation of the drying cylinder is set to be a period T, the detection times of the humidity sensor are n, wherein n is more than or equal to 10, the humidity sensor is controlled to detect once every time T1 = T/n, the humidity sensor can uniformly detect the whole circumference of clothes at intervals, and the accuracy of humidity difference measurement is ensured to the greatest extent.
In another scheme, a plurality of humidity sensors are arranged at different positions in the drying cylinder, when the fact that the clothes to be processed are dry is inferred, the humidity sensors detect humidity values of different positions of the clothes at the same time, whether the humidity difference value of the different positions of the clothes is larger than a standard humidity difference value is judged and analyzed, if yes, the clothes are judged to contain laundry detergent, the theoretical clothes processing program is inferred to be a washing program, and a user is prompted.
Further, 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 calculated respectively, and the humidity difference values are compared with the standard humidity difference values respectively;
and calculating the probability P that the humidity difference value of different parts of the clothes is larger than the standard humidity difference value, judging whether the probability P is larger than the set probability P0, and prompting a user if the probability P is larger than the set probability P0.
Further, if it is inferred that the theoretical laundry treatment program is inconsistent with the program selected by the user, the user is prompted by voice to perform the program currently being a non-washing program, for example, the user is prompted to perform the program currently being a sterilization/rejuvenation/deodorization or drying program, whether the user confirms the current program is performed is prompted, and if it is detected that the user inputs a "confirmation" signal to the control system or waits for t0 time that the user is still not responsive, the program selected by the user is normally performed.
Further, when the clothes to be treated are inferred to be dry clothes, detecting a user selection program, and if the user selection program is detected to be a sterilization/rejuvenation/deodorization program, normally executing according to the program selected by the user; if the program selected by the user is detected to be a drying program and the selected heating time is longer than the set time t0, prompting the user. When a user puts dry clothes in the drying cylinder and selects longer heating time, the clothes fiber is damaged, safety accidents are easy to cause, and the user is reminded in time at the moment, so that unnecessary loss is avoided.
The embodiment also provides a clothes drying device with the control method, which comprises the following steps: a humidity acquisition unit for acquiring humidity information of the laundry to be treated; and the control unit is used for comparing and analyzing the acquired clothes humidity information with the standard humidity information stored in the server and controlling the working state of the clothes treatment equipment according to the analysis result.
When the clothes drying equipment is a washing and drying combined machine, the upper cylinder of the washing and drying combined machine is a drying cylinder, the lower cylinder is a washing cylinder, the upper cylinder is used for drying, sterilizing, deodorizing and the like the clothes, and the lower cylinder is used for washing the clothes; the control unit of the washing and drying combined machine prompts the user to execute the program currently as a non-washing program according to the detection result of the humidity sensor, if the laundry to be processed contains laundry detergent and the theoretical laundry processing program is inferred to be inconsistent with the program selected by the user, for example, prompts the user to execute the program currently as a sterilization/refreshing/deodorizing or drying program, if the laundry is to be washed, the user is prompted to move the laundry to the lower drum (i.e. the washing drum), and prompts whether the user confirms to execute the current program, if the user inputs a confirmation signal to the control system or waits for t0 time, the user does not answer yet, and then the program selected by the user is executed normally.
When the clothes drying equipment is a clothes dryer, the drying cylinder is arranged in the clothes dryer, a control unit of the clothes dryer judges that a theoretical clothes treatment program is inconsistent with a program selected by a user according to the detection result of the humidity sensor, if the clothes to be treated are detected to contain laundry detergent, the user is prompted by voice to perform the program currently as a non-washing program, for example, the user is prompted to perform the program currently as sterilization/refreshing/deodorizing or drying program, whether the user confirms to perform the current program is prompted, and if the user is detected to input a confirmation signal to the control system or wait for t0 time, the user does not answer yet, the program selected by the user is normally performed.
According to the control method of the clothes drying equipment, the clothes to be processed are detected to be dry clothes or wet clothes through the humidity sensor, humidity values of different parts of the clothes are detected, whether the humidity differences of the different parts of the clothes are larger than the standard humidity differences or not is judged and analyzed, if yes, the clothes are judged to contain laundry detergent, a theoretical clothes processing program is deduced to be a washing program, a user is timely prompted, the phenomenon that the drying cylinder is used as the washing cylinder by mistake by the user is avoided, resource waste caused by idle work is effectively prevented, the user is timely helped to correct errors, and safety accidents are avoided.
Example two
In the control method provided in the first embodiment, whether the laundry contains the washing powder cannot be effectively judged by the humidity sensor, and it is difficult to judge the situation that the user puts the washing powder. Therefore, the present embodiment provides a control method of a clothes drying apparatus based on the first embodiment, and by using the method of clothes image recognition, it can be effectively deduced whether the clothes contain washing powder or liquid detergent, and further deduced the theoretical clothes treatment program.
Specifically, as shown in fig. 3 and fig. 4, a drying drum for holding the laundry is arranged in the laundry treatment apparatus, an image acquisition module is arranged in the drying drum, the image acquisition module acquires image information of the laundry to be treated in the drying drum and feeds back the image information to a control unit, the control unit deduces a theoretical laundry treatment program according to the acquired laundry image information, and judges whether the theoretical laundry treatment program is consistent with an actual laundry treatment program selected by a user, if so, the program selected by the user is normally executed; if not, prompting the user.
Further, 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 acquired image information of the clothes 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 carrying out image comparison again: if the washing powder/liquid detergent is determined, deducing that the theoretical clothes treatment program is a washing program, and prompting a user; if there is no detergent/liquid laundry detergent, it is inferred that the theoretical laundry treatment program is a non-washing program.
Further, the control unit compares the clothes image information acquired by the image acquisition module with pre-stored clothes image information, and analyzes the difference between the clothes image information and the pre-stored clothes image information, wherein the pre-stored clothes image information is a reference image for reflecting the dryness and humidity 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 difference comprises: the volume of the laundry to be treated changes; preferably, the difference further includes a change in the shade of the color of the laundry. For the clothes, when the humidity of the clothes is larger (larger than a certain threshold), the volume of the clothes is larger, namely, the larger the humidity is, the larger the volume is, at the moment, the volume of the clothes can be compared with the volume of the clothes when the humidity is lower than a certain threshold, when the volume difference of the clothes is larger, the clothes are determined to be dried, and it is noted that the volume can be a rough concept, and the occupied area of an object to be dried in a picture in the picture can be determined by photographing the image to be dried under the same environment. As another example, the laundry is different in color depth of water and no water, and thus, the dry and wet state of the laundry to be treated at present can be determined using the difference in the brightness of the colors.
Further, when the clothes to be treated are inferred to be dry, the detailed image information of the clothes to be treated is further analyzed, if the fact that more fine particles exist in the clothes is detected, 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 wind into the drying cylinder, and the washing powder is blown into the thread scraps filter at the bottom of the drying cylinder.
Preferably, when the drying cylinder is determined to contain washing powder, the drying cylinder is driven to rotate in a positive-negative alternating manner, and the clothes are subjected to shaking-off treatment. Washing powder on clothes can be well shaken off through the positive and negative rotation of the drying cylinder, so that the washing powder on the clothes can be conveniently removed.
Further, when the laundry is inferred to be dry, further analyzing image information of the laundry, if a plurality of inconsistent color shades of the laundry are detected, determining that the drying drum contains laundry detergent, deducing that the theoretical laundry treatment program is a washing program, and prompting a user. If the user puts the laundry detergent into the drying cylinder, the laundry detergent falling onto clothes can partially soak the clothes, the color is darker, the color is relatively lighter at the place where the clothes do not have the laundry detergent, whether the laundry detergent is contained on the clothes to be processed can be deduced by analyzing the color information of the clothes image, and if the laundry detergent is contained, the user can deduce that the user intends to execute the program as the washing program and prompt the user in time.
Further, the image acquisition module acquires image information of the clothes to be processed put into the drying cylinder by a user, the control unit compares the acquired image information of the clothes with the image information of the dry/wet clothes stored in the server, and if the clothes are determined to be wet clothes, the image information is normally executed according to a program selected by the user. When the clothes are determined to be wet clothes, the judgment is not needed to be continued, because the user cannot wash one wet clothes, and the wet clothes can be normally executed according to the program selected by the user.
According to the control method of the clothes drying equipment, the image acquisition module is used for acquiring the image information of the clothes to be processed, comparing and analyzing the acquired image information of the clothes to be processed with the clothes image stored in the service area, and deducing a theoretical clothes processing program when detecting the existence of washing powder or washing liquid, wherein the theoretical clothes processing program is a washing program and timely reminding a user, so that the waste of resources caused by idle work is effectively prevented, the user is timely helped to correct errors, and safety accidents are avoided.
The control method provided in this embodiment further combines the method of humidity detection in the first embodiment on the basis of the above-mentioned image recognition to infer whether the user theoretical laundry treatment program is consistent with the laundry treatment program selected by the user, so that the inferred result is more accurate.
Specifically, a humidity sensor is further arranged in the drying cylinder, when the humidity sensor detects that the humidity value of the clothes is larger than the standard humidity value, the clothes to be processed are inferred to be wet, 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, deducing that the clothes to be treated are dry clothes, and further deducing a theoretical clothes treatment program;
wherein the standard humidity value is the water content of the common unwashed clothes.
Further, when the clothes to be treated are inferred to be dry, the drying drum is controlled to rotate at a low speed, the humidity sensor detects humidity values of different parts of the clothes, whether the humidity difference value of the different parts of the clothes is larger than a standard difference value is judged and analyzed, if yes, the clothes are judged to contain laundry detergent, a theoretical clothes treatment program is inferred to be a washing program, and a user is prompted; if not, the program selected by the user is normally executed. How to calculate the humidity difference and how to determine whether the laundry detergent is contained on the laundry to be treated according to the humidity difference, the same method as that in the first embodiment is adopted, and will not be described herein again.
Further, when it is judged that the theoretical clothes treatment program is inconsistent with the program selected by the user, the user is prompted by voice to perform the program currently as a non-washing program, whether the user confirms to perform the current program or not is prompted, if the user is detected to input a confirmation signal to the control system or to wait for t1 to detect that the user still does not answer, the program selected by the user is normally performed.
According to the control method of the clothes drying equipment, provided by the invention, the clothes to be processed are judged and analyzed to be dry clothes or wet clothes by combining the image acquisition module and the humidity sensor, the humidity values of different parts of the clothes are detected, whether the humidity values of the different parts of the clothes are larger than the standard humidity values or not is judged and analyzed, if yes, the clothes are judged to contain laundry detergent, a theoretical clothes processing program is deduced to be a washing program, a user is timely prompted, the phenomenon that the drying cylinder is mistaken as a washing cylinder by the user is avoided, and the method is more efficient.
