Description
Technical Field
The present disclosure relates to the field of laundry treatment technologies, and in particular, to a control method of a laundry treatment apparatus and a laundry treatment apparatus.
Background
Most of the existing clothes treatment devices are fully automatic clothes treatment devices, namely, after program parameters are set, the clothes treatment devices automatically perform washing, rinsing, dewatering and other processes according to programs. The whole process from the washing of the clothes to the spin-drying of the clothes can be completed without manual participation, so that the convenience of using the washing machine by people is improved.
However, in the current full-automatic washing machine, once a certain program is selected, parameters (including washing time, rinsing times, dewatering time, etc.) in the whole clothes treatment process corresponding to the program are determined, and real-time change cannot be performed in the clothes treatment process. The following problems are easily caused: for clothes which do not need to be washed for too long (such as clothes with lower dirt degree), the clothes are washed for too long, so that washing time is wasted; for the clothes which need deep cleaning (such as the clothes with high dirt degree), the washing time is insufficient, so that the clothes are not completely washed, and the washing is finished. Therefore, the current full-automatic washing machine has low intelligent degree of the washing program, and the washing program cannot be adjusted according to the real-time washing condition, so that the washing efficiency is low.
In addition, when the washing program is generated according to the dirt degree of the clothes in the conventional washing machine, the detection of the dirt degree of the clothes is performed before the formal washing, the detection accuracy is low, and the washing program generated according to the detected dirt degree of the clothes cannot be adjusted in real time in the formal washing process, so that the dirt of the clothes cannot be effectively removed by the performed washing program, and the problem of low washing efficiency exists.

Detailed Description
It should be noted that, in the case of no conflict, the embodiments and technical features in the embodiments may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present application and should not be construed as undue limitation to the present application.
The present embodiment provides a laundry treatment apparatus, which includes, but is not limited to, a pulsator type washing machine, a drum type washing machine, etc., and the laundry treatment apparatus includes a conventional structure such as a water intake assembly, a washing tub, a drain assembly, a driving device, etc., which are well known to those skilled in the art for realizing the normal operation of the laundry treatment apparatus, and thus, are not described herein. The laundry treating apparatus further includes a control method in any of the embodiments of the present application, and the control method provided by the present application will be described in detail below.
Fig. 1 is a control method of a laundry treatment apparatus according to an embodiment of the present application, as shown in fig. 1, the control method includes: dividing a stain cleaning phase into a plurality of successive sub-cleaning phases; acquiring a turbidity value of the current sub-cleaning stage; based on the turbidity value of the current sub-cleaning stage, whether the laundry treating apparatus enters the next sub-cleaning stage of the current sub-cleaning stage is controlled.
The essence of the laundry treatment apparatus for treating laundry is a process of gradually peeling off dirt attached to laundry by mechanical, chemical, etc., and the more dirt is peeled off, the higher the dirt content of water is. In the present application, the content of dirt in the washing water is referred to as a turbidity value (hereinafter referred to as a turbidity value Z) of the washing water, and the turbidity value can be calibrated by an index such as a volume concentration or mass fraction of dirt in the washing water. The turbidity value of the washing water intuitively reflects the peeling amount of stains on the laundry. As the washing process advances, stains on the laundry are continuously stripped into the water, and the turbidity value of the washing water increases. When stains on clothes are stripped off, turbidity values of washing water tend to be saturated, and therefore, changes (increase or tend to be saturated) of the turbidity values can show whether the clothes are washed clean or not.
The whole stain cleaning process is divided into a plurality of continuous sub-cleaning processes, and whether the stain cleaning process of the clothes treatment equipment is to be continued is controlled according to turbidity values detected in real time in each sub-cleaning process. When it is determined that the progress of cleaning the stains is necessary to proceed according to the turbidity value detected in real time, it is indicated that the laundry is not washed and further cleaning is required, so that it is ensured that the progress of cleaning the stains is stopped after the laundry is sufficiently washed; on the other hand, when it is determined that the stain cleaning process is not necessary to continue according to the turbidity value detected in real time, it is explained that the laundry is washed, and the stain on the laundry is not required to continue to be washed, so that the stain cleaning process can be ensured to be stopped in time after the laundry is treated cleanly, and the stain cleaning process is not required to be ended until the predetermined program of the whole stain cleaning stage is completely operated once, thereby avoiding the waste of washing time. Therefore, the washing process can be stopped in time after the clothes are washed completely, unnecessary waste of washing time is reduced, and intelligent control of the clothes treatment equipment on the washing process is realized.
It should be noted that, the stain treatment stage is divided into a plurality of continuous sub-cleaning stages, and the term "continuous" does not mean that no pause exists between two adjacent sub-cleaning stages, and in fact, operations such as stopping, switching between forward and reverse rotation, water supplementing and the like can exist between two adjacent sub-cleaning stages; it should be understood here that no draining and/or dewatering action is involved between the two sub-cleaning phases.
According to the control method provided by the embodiment of the application, the stain cleaning stage is divided into a plurality of continuous sub-cleaning stages, so that the turbidity value change of each sub-cleaning stage can be ensured to be only related to the washing process, and the clothes treatment equipment can accurately and reliably control the washing process according to the turbidity value. Specifically, since the plurality of sub-cleaning stages are successive washing processes, the drainage and/or dehydration actions are not included between the two sub-cleaning stages, so that as the washing process advances, stains peeled off from laundry in succession can be accumulated in the washing water, and the amount of the stains is increased, resulting in a gradual increase in the turbidity value of the washing water. Thus, dividing the stain cleaning stage into a plurality of successive sub-cleaning stages ensures that the factors affecting the change in turbidity value are only related to the wash course, facilitating the laundry treatment apparatus to control the wash course in accordance with the change in turbidity value.
In some embodiments, obtaining turbidity values for a current sub-cleaning phase herein includes: acquiring turbidity values of at least three time nodes in the current sub-cleaning stage; taking the average value of the turbidity values of the at least three time nodes as the turbidity value of the current sub-cleaning stage. The three time nodes may be uniformly distributed in the sub-cleaning stage, for example, the three time nodes may be the initial time t0, the middle time t1/2, and the end time t1 of the sub-cleaning stage respectively. By measuring turbidity values at a plurality of times in one washing sub-stage and taking the average value as the turbidity value of the washing sub-stage, the measurement accuracy of the turbidity value of each sub-cleaning stage can be improved.
In some embodiments, the present application controls whether the laundry treatment apparatus enters a next sub-cleaning phase of the current sub-cleaning phase based on the turbidity value of the current sub-cleaning phase, comprising: determining that the turbidity value of the current sub-cleaning stage is larger than a preset turbidity value, and controlling the clothes treatment equipment to enter the next sub-cleaning stage of the current sub-cleaning stage; and/or determining the turbidity value of the current sub-cleaning stage, wherein the turbidity value of the current sub-cleaning stage is increased relative to the turbidity value of the last sub-cleaning stage of the current sub-cleaning stage, and controlling the clothes treatment device to enter the next sub-cleaning stage of the current sub-cleaning stage.
The preset turbidity value can be a turbidity index value corresponding to the identification of the clothes to be washed clean in the washing machine industry. The preset turbidity value may be pre-stored in a memory of the laundry treating apparatus before the laundry machine leaves the factory. According to the control method, the turbidity value obtained in real time is compared with the preset turbidity value, so that whether the stain cleaning is continuously executed or not is controlled, and the control logic is simple and easy to realize.
The preset turbidity value is taken as a reference value, the control logic is simple in nature and low in implementation difficulty, however, because the preset turbidity value is the turbidity value measured under the condition that clothes are clean, in the practical application process, the turbidity value of the first sub-cleaning stage is higher than the preset turbidity value, the turbidity value of washing water gradually increases along with the advancement of the spot cleaning process, the turbidity value of each sub-cleaning stage is larger than the preset turbidity value, so that the result of each judgment is that the washing needs to be continued, and even if the preset sub-cleaning stage of the spot cleaning stage is operated once, the judgment result of the control logic is that the washing needs to be continued, and the spot cleaning stage is separated into the sub-cleaning stages and loses meaning.
In view of this, the control method provided in the present application may further determine whether the stain cleaning is performed continuously by comparing the turbidity values obtained in real time at each sub-cleaning stage with each other. Specifically, by comparing the turbidity value of the current sub-cleaning stage with the turbidity value of the previous sub-cleaning stage of the current sub-cleaning stage, if the turbidity value of the current sub-cleaning stage is increased relative to the turbidity value of the previous sub-cleaning stage of the current sub-cleaning stage, it is indicated that dirt is still stripped off the clothes in the current sub-cleaning stage, and the current sub-cleaning stage may be in the increasing stage of the dirt stripping amount or in the saturation stage of the dirt stripping amount, but the next sub-cleaning stage is required to be entered to further detect the change of the turbidity value, so as to determine the dirt cleaning on the clothes.
In some embodiments, the two approaches may complement each other, functioning in different stain cleaning processes, to achieve intelligent control of the laundry treatment apparatus. For example, if the laundry treating apparatus is controlled to continue to be executed in the second mode, after the first sub-cleaning stage is completed and the relevant turbidity value is detected, the turbidity value of the first sub-cleaning stage is not compared with the turbidity value of the sub-cleaning stage because the first sub-cleaning stage is not preceded by the sub-cleaning stage. Therefore, the control method provided by the application can control whether the clothes treatment equipment enters the second sub-cleaning stage by comparing the turbidity value of the first sub-cleaning stage with the preset turbidity value, and the turbidity values of the sub-cleaning stages are compared with each other in the second mode in the subsequent stain cleaning process. Therefore, the two modes work together to realize intelligent control of the stain cleaning process.
In some embodiments, the control method of the present application comprises: and determining that the accumulated times of the turbidity values of the adjacent two sub-cleaning stages not increasing reach the preset times, and controlling the clothes treatment equipment to finish the stain cleaning stage. Specifically, the turbidity value of the adjacent two sub-cleaning stages did not increase, indicating that the stain content in the wash water did not increase in the adjacent two sub-cleaning stages. When the accumulated times of not increasing the turbidity values of the adjacent two sub-cleaning stages reach the preset times, namely, the soil contents of the continuous multiple sub-cleaning stages are not increased, the soil quantity stripped into water tends to be saturated in the soil cleaning process, which means that the soil on clothes is basically stripped and cleaned, and the washing process can be finished.
Here, the cumulative number of times that the turbidity value does not increase in the adjacent two sub-cleaning stages means the number of consecutive sub-cleaning stages in which the turbidity value does not increase. For example, in the stain treatment stage, the sub-cleaning stages are performed as s1, s2, s3, s4, s5, s6, respectively, and if the turbidity value of the s1-s3 sub-cleaning stages is gradually increased, the turbidity value of the s4 stage is not increased relative to the turbidity value of the s3 stage, the cumulative number of times that the turbidity values of the adjacent two sub-cleaning stages are not increased is 1; further, if the turbidity value of the s5 stage is not yet increased relative to the turbidity value of the s4 stage, the cumulative number of times that the turbidity values of the adjacent two sub-cleaning stages are not increased is 2; further, if the turbidity value of the s6 stage is not yet increased relative to the turbidity value of the s5 stage, the cumulative number of times that the turbidity values of the adjacent two sub-cleaning stages are not increased is 3. However, if the turbidity value of the s4 stage is not increased relative to the turbidity value of the s3 stage, but the turbidity value of the s5 stage is increased relative to the turbidity value of the s4 stage, the cumulative number of times that the turbidity values of the adjacent two sub-cleaning stages are not increased is 0.
That is, in the control method of the present application, in order to ensure that the laundry is sufficiently washed clean and then the washing is finished, it is necessary that the laundry treatment apparatus controls the finishing of the stain cleaning process after the number of consecutive sub-cleaning stages, in which the turbidity value is not increased, reaches the preset number. Because in practical application, the cumulative number of times that the turbidity values of the adjacent two sub-cleaning stages are not increased is 1, it is possible that the detection error is caused. For example, in the six sub-cleaning stages s1 to s6, the turbidity value of the s4 stage is not increased relative to the turbidity value of the s3 stage, but the turbidity value of the s5 stage is increased relative to the turbidity value of the s4 stage, and the turbidity value of the s4 stage is not increased relative to the turbidity value of the s3 stage and is not representative, so that the clothes can not be determined to be washed cleanly. In order to further ensure the clothes to be washed clean, only when the accumulated times of the turbidity values of the two adjacent sub-cleaning stages are not increased reach the set times, the stain treatment stage does not need to enter the next sub-cleaning stage of the current sub-cleaning stage; if the accumulated times of the turbidity values of the two adjacent sub-cleaning stages cannot reach the set times, the stain treatment stage needs to enter the next sub-cleaning stage to continue washing in order to ensure the clothes to be washed clean.
From the above discussion, it is clear that the longer the cumulative number of times the turbidity value of the adjacent two sub-cleaning stages does not increase, the longer the duration of no soil peeling on the laundry. In some embodiments, in order to avoid waste of washing time, it may be determined that laundry is washed clean when the cumulative number of times that turbidity values of adjacent two sub-cleaning stages are not increased reaches 2 times, to end the washing process.
Therefore, the control method of the clothes treatment equipment provided by the embodiment of the application judges whether to continue washing based on the turbidity value, is accurate and reliable, and achieves the intellectualization of the clothes treatment equipment in the aspect of washing process control.
Further, before the determining whether the stain treatment stage enters the next sub-cleaning stage of the current sub-cleaning stage based on the turbidity value of the current sub-cleaning stage, the control method further includes: and determining that the accumulated times of the sub-cleaning phases executed in the stain treatment phase reach the maximum allowable execution times of the sub-cleaning phases, and controlling the clothes treatment equipment to end the stain cleaning phase. In the application, the stain treatment stage is divided into N sub-cleaning stages, N is a positive integer, and the value of N can be established after the factors such as the acceptable washing time of daily washing people, the cleaning time required by the clothes dirt procedure and the like are comprehensively considered by manufacturers before the clothes treatment equipment leaves the factory; alternatively, when the laundry treatment apparatus has the cloud computing function, the value of N may be generated by the laundry treatment apparatus performing big data analysis according to the daily washing condition of the user. N is stored in the laundry treating apparatus in advance. In the operation of the sub-cleaning stage, it is necessary to monitor whether the accumulated number of times of the sub-cleaning stage that has been performed is greater than N, so as to reduce unnecessary waste of washing time.
Further, in the control method provided by the embodiment of the present application, after determining that the stain treatment stage needs to enter a next sub-cleaning stage of a current sub-cleaning stage, the washing parameters of the next sub-cleaning stage of the current stage are automatically adjusted based on a ratio of the turbidity value of the current sub-cleaning stage to the turbidity value of a previous sub-cleaning stage of the current stage. As mentioned above, dividing the stain cleaning phase into a plurality of successive sub-cleaning phases ensures that the change in turbidity value of each sub-cleaning phase is only dependent on the wash course. The ratio of the turbidity values of the adjacent two sub-cleaning stages can reflect the change trend of the amount of the stripped stains on the clothes along with the progress of the washing process, and the amount of the stripped stains on the clothes is directly related to the washing strength. Therefore, the change trend of the amount of the peeled stain on the laundry can be determined by comparing the ratio of the turbidity values of the adjacent two sub-cleaning stages, and then the demand for the washing strength can be determined, and the washing strength can be determined by setting the washing parameter. Therefore, the control method provided by the application can adjust the washing parameters in the washing process according to the real-time washing requirement, and the intelligent control of the washing process in the washing process is realized.
Fig. 2 is a control method of automatically adjusting washing parameters of a laundry treating apparatus according to an embodiment of the present application. As shown in fig. 2, the laundry treating apparatus determines that the main washing stage is to enter the i+1 th sub-cleaning stage, and then the washing parameter of the i+1 th sub-cleaning stage may be determined based on a ratio of the turbidity value Z (i) of the i-th sub-cleaning stage to the turbidity value Z (i-1) of the i-1 th sub-cleaning stage. If the ratio of the turbidity value of the i-th sub-cleaning stage to the turbidity value of the i-1 th sub-cleaning stage is larger, the increment of the dirt peeled into the water from the i-1 th sub-cleaning stage to the i-th sub-cleaning stage is larger, namely the dirt on the clothes is more, so that the washing needs to be enhanced in the subsequent washing process; if the ratio of the turbidity value of the second sub-cleaning stage to the turbidity value of the first sub-cleaning stage is small, it means that the increase of the dirt peeled into the water from the i-1 th sub-cleaning stage to the i-th sub-cleaning stage is small, i.e., the dirt on the laundry is not particularly large, and thus, it can be moderately gentle in the subsequent washing process.
Optionally, in the present application, after determining that the stain treatment stage needs to enter a next sub-cleaning stage of the current sub-cleaning stage, the washing parameters of the next sub-cleaning stage of the current sub-cleaning stage are automatically adjusted based on a ratio of the turbidity value of the current sub-cleaning stage to the turbidity value of the last sub-cleaning stage of the current sub-cleaning stage, where the washing parameters include a washing beat and a washing time. Both the washing tempo and the washing time can affect the washing intensity. When the ratio of the turbidity value of the current sub-cleaning stage to the turbidity value of the last sub-cleaning stage of the current sub-cleaning stage is larger, the washing strength can be increased by increasing the washing beat and prolonging the washing time; when the ratio of the turbidity value of the current sub-cleaning stage to the turbidity value of the last sub-cleaning stage of the current sub-cleaning stage is small, the beating frequency of the washing beats can be properly reduced, and the washing time can be shortened, so that the washing strength can be properly weakened.
As can be seen from the above discussion, in the present application, the washing parameters of the laundry treatment apparatus in each sub-cleaning stage can be adjusted according to the actual washing situation, so as to achieve the intellectualization of the washing procedure. The laundry treating apparatus may adjust the washing parameter to enhance washing when it is judged that the washing intensity needs to be increased, and may adjust the washing parameter to reduce the washing intensity when it is judged that the washing is required to be gentle, based on the detection of the turbidity value. Thus, the clothes are prevented from being greatly worn by long-time high-strength washing, and unnecessary electric energy waste is reduced; it is also possible to avoid the situation that the laundry is not washed cleanly due to the need of strong washing but insufficient actual washing strength.
Further, in order to ensure that the washing parameters of the second sub-cleaning stage are controllable, the control method further includes: an initial turbidity value of the stain treatment stage is obtained. Thus, the washing parameters of the second sub-cleaning stage may be determined based on the ratio of the turbidity value of the first sub-cleaning stage to the initial turbidity value.
Optionally, obtaining the initial turbidity value of the stain treatment stage comprises: putting the laundry into washing water of the clothes treatment equipment, and soaking for 5-10min; and detecting the turbidity value of the washing water after the clothes are soaked for 5-10 min.
Fig. 3 is a laundry cleaning flow of a laundry treatment apparatus according to an embodiment of the present application, and as shown in fig. 3, the laundry cleaning flow includes: a water inlet stage, a main washing stage, a water discharge stage, a rinsing stage and a dewatering stage. In some embodiments, the stain cleaning stage comprises a main wash stage, or the stain cleaning stage comprises a rinse stage.
That is, the control method provided by the application is not only suitable for the main washing process of clothes, and is also suitable for the rinsing process after the clothes are washed, so that the intelligent control of the rinsing process is realized, the treatment efficiency of the clothes is effectively improved, and unnecessary waste of water, electricity and other resources is avoided.
Further, in the present application, the control method further includes: after the stain cleaning stage is completed, the clothes treatment equipment is controlled to perform a water draining action. That is, the control method of the present application controls the laundry treating apparatus not to drain water during a plurality of consecutive sub-cleaning stages of the entire soil cleaning stage, and to drain water after the soil cleaning stage is completed.
Fig. 4 is a flowchart of a control method provided in an embodiment of the present application. As shown in fig. 4, the control method includes:
s1, dividing a main washing stage into N sub-cleaning stages, wherein N is more than or equal to 1, N is an integer, and recording an initial turbidity value;
s2, entering a first sub-cleaning stage for washing, and obtaining a turbidity value of the first sub-cleaning stage;
s3, judging whether the turbidity value of the first sub-cleaning stage is smaller than a preset turbidity value or not; if yes, the main washing stage is ended; if not, entering step S4;
s4, judging whether the accumulated times of the sub-cleaning stage reach N; if yes, the main washing stage is ended; if not, entering step S5;
s5, entering an ith sub-cleaning stage, wherein i is more than or equal to 2 and less than or equal to N, i is an integer, and the turbidity value of the ith sub-cleaning stage is obtained;
s6, judging whether the turbidity value of the ith sub-cleaning stage is increased relative to the turbidity value of the i-1 th sub-cleaning stage; if yes, entering an i+1th sub-cleaning stage, returning to the step S4, and if not, entering a step S7;
s7, judging whether the accumulated times of the turbidity values of the two adjacent sub-cleaning stages not increasing reach 2 times, if so, ending the main cleaning stage, and if not, returning to the step S4.
As shown in fig. 3, the laundry treating process includes a water inlet stage, a main washing stage, a water draining stage, a rinsing stage, and a dehydrating stage in the present application. The water inlet stage is to feed water into the clothes treatment equipment through a water inlet component on the clothes treatment equipment so as to supply clean water necessary for washing clothes, and generally, in order to improve the cleaning effect, a detergent is also put in the water inlet stage. After the water inflow reaches the preset water inflow, the washing machine enters a main washing stage, and dirt attached to the clothes is separated from the clothes through mechanical and chemical actions and dissolved in the water. After the main washing stage is finished, the washing machine enters a drain stage for draining the washing water containing dirt. As can be seen from fig. 3, the laundry treating apparatus does not drain water in the main washing stage, and only drains water after the main washing stage is finished. That is, the "the main washing stage is divided into a plurality of sub-cleaning stages" described in the present application means that the plurality of sub-cleaning stages are all preceded by the drainage stage, and the plurality of sub-cleaning stages are substantially continuous washing processes, and no drainage is performed between adjacent two sub-cleaning stages. It should be noted that the "continuous washing process" may allow a short dwell between two adjacent sub-washing phases, for example, a switching of the pulsator of the laundry treatment device between forward and reverse rotation may be stopped for a few seconds, and for example, a change of the washing parameters of the sub-cleaning phase may be stopped for a few seconds when the washing parameters are changed. In the present application, the adjacent two sub-cleaning stages are continuous washing processes, so that the turbidity values of the adjacent two sub-cleaning stages have the same comparison basis, and the variation trend of the turbidity values of the adjacent two sub-cleaning stages mainly depends on the washing procedures of the adjacent two sub-cleaning stages. By analyzing the change of the turbidity value, determining whether the main washing stage is to be continuously executed on the basis of the executed sub-cleaning stage, so as to ensure that the main washing stage is finished in time on the basis of fully and cleanly washing clothes; on the other hand, the laundry treating apparatus may adaptively adjust the washing course by analyzing the change of the turbidity value to improve washing efficiency of the laundry treating apparatus.
In fig. 4, obtaining the initial turbidity value of the main wash stage comprises: putting the laundry into washing water of the clothes treatment equipment, and soaking for 5-10min; and detecting the turbidity value of the washing water after the clothes are soaked for 5-10 min. The purpose of obtaining the initial turbidity value is to base a comparison of the turbidity values obtained in the subsequent sub-cleaning phase.
In fig. 4, the preset turbidity value may be equal to the initial turbidity value, or may be a turbidity value recognized as clean laundry in the washing machine industry.
In step S5, the washing course of the i-th sub-washing stage may be determined based on the ratio of the turbidity value of the i-1 th sub-washing stage to the turbidity value of the i-2 th sub-washing stage. It should be noted that, when i=2, the washing procedure of the 2 nd sub-washing stage may be determined based on the ratio of the turbidity value of the 1 st sub-washing stage to the initial turbidity value.
After the main washing stage is finished, the laundry treating apparatus is controlled to enter a drain stage.
The present application also provides a laundry treatment apparatus, the laundry treatment apparatus comprising: a control computer board comprising a processor and a memory, wherein the memory is for storing a computer program capable of running on the processor; the processor is configured to execute the control method when running the computer program. The laundry treating apparatus further includes: the washing barrel is used for containing clothes and washing water; and the turbidity sensor is used for detecting the turbidity value of the washing water in the washing barrel.
Optionally, in order to improve the detection accuracy, at least two turbidity sensors are arranged at the bottom of the washing barrel at intervals.
The clothes treatment equipment provided by the application monitors the turbidity value of the washing water in the washing barrel in real time through the turbidity sensor, and transmits the monitored turbidity value to the processor and the memory. The processor and the memory determine whether the washing process is continued or not based on the monitored turbidity value, and how to change the washing parameters to continue washing, so as to realize intelligent control of the washing program of the clothes treatment equipment.
The various embodiments/implementations provided herein may be combined with one another without conflict.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations can be made by those skilled in the art.
