Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and specifically relates to a control method for a washing equipment system and a washing equipment system. Background Art

[0002] As a kind of household appliance most widely used in people's daily life, washing equipment helps people get rid of the trouble of doing laundry and brings great convenience to people. However, with the increasing variety and functions of washing equipment, while making it more suitable for different washing needs of users, it is difficult to control the water inlet flow intensity during the washing cycle and the rotation of the washing tub to make them match the actual dirt level of the clothes and the washing needs of users. The washing needs of users include avoiding weak water inlet flow that causes the clothes not to be washed clean, and strong water inlet flow that causes large wear and great damage to the clothes.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method for a washing equipment system and a washing equipment system. By comparing the stain indices of at least two washing waters during the current washing process, the water inlet flow intensity and the rotation of the washing tub in the next washing process are adjusted, so that the rotation of the washing tub and the water inlet flow intensity match while conforming to the actual dirt level of the clothes, realizing the cleaning of the clothes and the water inlet flow not damaging the clothes, and better meeting the washing needs of users.

[0005] The basic concept of the technical solution adopted by the present invention to solve the above technical problem is as follows:

[0006] The present invention provides a control method for a washing equipment system, including the following steps:

[0007] Step S1: During each washing process, the washing equipment obtains the stain indices of at least two washing waters;

[0008] Step S2: Compare the stain indices of at least two washing waters to obtain a comparison result;

[0009] Step S3: According to the comparison result, adjust the water inlet flow intensity in the next washing process and set the rotation of the washing tub corresponding to the water inlet flow intensity.

[0010] By comparing the stain indices of at least two washing waters during the current washing process, the present invention adjusts the water inlet flow intensity and the rotation of the washing tub in the next washing process, so that the rotation of the washing tub and the water inlet flow intensity match while conforming to the actual dirt level of the clothes, realizing the cleaning of the clothes and the water inlet flow not damaging the clothes, and better meeting the washing needs of users.

[0011] A further solution of the present invention is as follows: in step S1, during the current washing process, the washing device obtains the stain indices of at least two washing waters.

[0012] In step S2, compare the stain indices of at least two washing waters to obtain the maximum value and the minimum value among them, and take the difference between the maximum value and the minimum value as the comparison result.

[0013] A further solution of the present invention is as follows: in step S1, obtain the first stain index at the start stage of the current washing process and obtain the second stain index at the end stage of a washing process.

[0014] In step S2, subtract the first stain index from the second stain index for comparison, and take the difference as the comparison result.

[0015] In the above solution, it is achieved that the actual amount of dirt washed out in the current washing process can be obtained only through the difference between two stain indices, ensuring the accuracy of the detection.

[0016] A further solution of the present invention is as follows: in step S1, during the current washing process, set the first detection duration and the second detection duration. During the first detection duration and the second set duration, the washing device respectively obtains the stain indices of at least two washing waters for each detection duration.

[0017] In step S2, calculate the average value of the stain indices of at least two washing waters respectively to obtain the first average value for the first detection duration and the second average value for the second detection duration. Subtract the first average value from the second average value for comparison, and take the difference as the comparison result.

[0018] In the above solution, the accuracy of the actual amount of dirt washed out in the current washing process obtained is further ensured by the difference between the first average value and the second average value.

[0019] A further solution of the present invention is as follows: step S3 includes:

[0020] Set a decreasing difference upper limit, a difference lower limit, and a washing completion lower limit in sequence;

[0021] If the difference is greater than the difference upper limit, adjust the incoming water flow intensity of the next washing process to the weak water flow gear;

[0022] If the difference is less than the difference lower limit and greater than the washing completion lower limit, adjust the incoming water flow intensity of the next washing process to the strong water flow gear;

[0023] If the difference is less than or equal to the difference upper limit and greater than or equal to the difference lower limit, make the incoming water flow intensity gear of the next washing process the same as that of the current washing process.

[0024] In the above solution, the water inlet flow intensity gear for the next washing process is adjusted according to the comparison result of the stain indexes of at least two washing waters during the current washing process, ensuring an appropriate water inlet flow intensity.

[0025] A further solution of the present invention is that step S3 includes:

[0026] The rotation of the washing tub includes the rotation-stop duration ratio of the washing tub, and the rotation-stop duration ratio of the washing tub is the ratio of the duration of one rotation of the washing tub to the duration of stopping rotation after this rotation;

[0027] Set the rotation-stop duration ratio of the washing tub corresponding to the weak water flow gear to be less than that of the standard water flow gear.

[0028] Set the rotation-stop duration ratio of the washing tub corresponding to the strong water flow gear to be greater than that of the standard water flow gear.

[0029] In the above solution, it is ensured that the water inlet flow intensity and the rotation-stop duration ratio of the washing tub are matched while conforming to the actual dirt degree of the clothes, realizing the cleaning of the clothes and the water inlet flow not damaging the clothes, and better meeting the washing needs of users.

[0030] A further solution of the present invention is that before the next washing process is run by the washing equipment, the number of times exceeding the upper limit of the cumulative difference greater than the upper limit of the difference and the number of times exceeding the lower limit of the cumulative difference less than the lower limit of the difference and greater than the lower limit of cleaning are counted;

[0031] The rotation of the washing tub further includes the motor speed of the washing tub rotation;

[0032] Set the rotation-stop duration ratio of the washing tub corresponding to the extremely weak water flow gear to be less than that of the weak water flow gear.

[0033] Set the rotation-stop duration ratio of the washing tub corresponding to the extremely strong water flow gear to be greater than that of the strong water flow gear.

[0034] Set the motor speed of the washing tub corresponding to the weak water flow gear to be less than that of the standard water flow gear.

[0035] Set the motor speed corresponding to the extremely strong water flow gear to be greater than that of the strong water flow gear.

[0036] If the number of times exceeding the upper limit reaches the first upper limit of the number of times, adjust the water inlet flow intensity of the next washing process to the extremely weak water flow gear;

[0037] If the number of times exceeding the lower limit reaches the first lower limit of the number of times, adjust the water inlet flow intensity of the next washing process to the extremely strong water flow gear.

[0038] In the above solution, when it is still detected that the amount of dirt actually washed out is more or less after multiple washing processes, the water inlet flow rate gear is further adjusted to make the water inlet flow intensity, the rotation-stop duration ratio of the washing tub, and the motor speed match while conforming to the actual dirt degree of the clothes, achieving the cleaning of the clothes and the water inlet flow not damaging the clothes, and better meeting the washing needs of users.

[0039] A further solution of the present invention is: setting a second upper limit greater than the first upper limit and a second lower limit greater than the first lower limit;

[0040] If the number of times exceeding the upper limit reaches the second upper limit, a reminder is sent to the user, the dosing ratio of the clothing treatment agent in the next washing process is reduced, and the water inlet flow intensity, the rotation-stop duration ratio of the washing tub, and the motor speed in the next washing process are adjusted to the standard gear;

[0041] If the number of times below the lower limit reaches the second lower limit, a request message asking whether to execute the next washing process is sent to the user, and the execution of the next washing process is stopped before receiving the instruction to execute the next washing process.

[0042] In the above solution, when there is dirt that cannot be washed clean through multiple washing processes, such as color-fast clothes and excessive addition of detergent, a reminder is sent to the user, and the water inlet flow intensity, the rotation-stop duration ratio of the washing tub, and the motor speed in the next washing process are adjusted to further make the water inlet flow intensity, the rotation-stop duration ratio of the washing tub, and the motor speed conform to the actual dirt degree of the clothes, which is green and environmentally friendly. And when there are clothes that are detected as not dirty through multiple washing processes, a request message asking whether to execute the next washing process is sent to the user to confirm whether the clothes are really not dirty and whether the clothes need to be further washed to be cleaner, further meeting the washing needs of users, which is green and environmentally friendly.

[0043] The present invention also provides a washing equipment system, including:

[0044] A washing module for washing clothes;

[0045] An optical detection module for detecting the stain index in the washing module;

[0046] A control module, communicatively connected to the optical detection module, for receiving the stain index of the optical detection module and adjusting the water inlet flow intensity and the rotation of the washing tub in the next washing process of the washing module according to the stain index.

[0047] A further solution of the present invention is: the washing equipment system includes a washing equipment and a mobile device;

[0048] The washing device sends reminder and request information to the user and receives an instruction to execute the next washing process.

[0049] And / or, after receiving the signal from the washing device, the mobile device sends reminder and request information to the user, and after receiving the instruction to execute the next washing process, sends a signal to the washing device.

[0050] In the above solution, by the washing device and / or the mobile device receiving the signal of the washing device, it is realized that the user can more conveniently receive reminder and request information.

[0051] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0052] Based on the comparison result of the stain indices of at least two washing waters in the current washing process, the incoming water flow intensity of the next washing process and the rotation of the washing tub are adjusted, so that the rotation of the washing tub and the incoming water flow intensity are matched while conforming to the actual dirtiness of the clothes, realizing the cleaning of the clothes and the incoming water flow not damaging the clothes, and better meeting the washing needs of the user.

[0059] It should be noted that these drawings and text descriptions are not intended to limit the inventive concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Specific Embodiments

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0061] As Figures 1 to 4 shown, the present invention provides a control method for a washing equipment system and a washing equipment system. By comparing the stain indices of at least two washing waters during the current washing process, the inlet water flow intensity and the rotation of the washing tub in the next washing process are adjusted, so that the rotation of the washing tub and the inlet water flow intensity match while conforming to the actual dirtiness of the clothes, achieving the cleaning of the clothes and the inlet water flow not damaging the clothes, and better meeting the washing needs of users.

[0062] Embodiment 1

[0063] As Figures 1 to 4 shown, the present invention provides a control method for a washing equipment system. The control method includes repeatedly performing a washing process of adding a laundry treatment agent in the washing equipment, including the following steps: Step S1, during each washing process, the washing equipment obtains the stain indices of at least two washing waters; Step S2, comparing the stain indices of at least two washing waters to obtain a comparison result; Step S3, adjusting the inlet water flow intensity in the next washing process according to the comparison result and setting the rotation of the washing tub corresponding to the inlet water flow intensity.

[0064] Specifically, the stain index is a feedback variable obtained by optical detection modules such as a near-infrared spectrum sensor and an ultraviolet spectrum sensor, and is preferably obtained through an ultraviolet spectrum sensor module. Further, the ultraviolet spectrum sensor uses ultraviolet absorption spectroscopy to detect the stain index. Ultraviolet absorption spectroscopy detects the stain index through the corresponding relationship between the substance and its ultraviolet-visible spectroscopy (UV-VIS) when the substance absorbs light of a specific wavelength to reach the maximum value. The electromagnetic wave wavelength corresponding to the ultraviolet spectrum sensor is shorter and has greater energy, which can penetrate tiny bubbles and has a good response to micron-sized particles. The stain index includes various substances that cannot be detected by conventional sensors. The conventional sensor is, for example, an infrared pair tube sensor, which cannot detect organic soluble stains, including oily stains, proteins, laundry treatment agents, and emulsions, etc. The ultraviolet spectrum sensor can detect the above-mentioned organic soluble stains and can also detect insoluble particulate matter. Among them, the protein in the organic soluble stain includes sweat stains. Therefore, the ultraviolet spectrum sensor can better detect the stain index of the laundry treatment agent and dirt in the water while having a larger detection range.

[0065] Further, the band of the soiled area in the ultraviolet-visible spectrum is compared with the spectral band of the stain index obtained by detection, so as to obtain a more accurate stain index of the soiled area.

[0066] Further, when no clothes are placed in the washing tub, the stain index collected by the ultraviolet light spectrum sensor is received, and multiple stain indexes are stored as historical data in the storage module. A stain index reference value is established according to the historical data. For example, the average value of the historical data is obtained as the stain index reference value. According to the stain index reference value, the stain index collected by the optical detection module when clothes are placed in the washing tub is corrected. For example, the stain index when clothes are placed in the washing tub is subtracted by the stain index reference value to obtain a corrected stain index.

[0067] Therefore, through the comparison results of the stain indexes of at least two washing waters during the current washing process, the water inlet flow intensity of the next washing process and the rotation of the washing tub are adjusted, so that the rotation of the washing tub and the water inlet flow intensity match while conforming to the actual soiling degree of the clothes, realizing the cleaning of the clothes and the water inlet flow not damaging the clothes, and better meeting the washing needs of users.

[0068] As a specific implementation manner of this embodiment, in step S1, during the current washing process, the washing device obtains the stain indexes of at least two washing waters; in step S2, the stain indexes of at least two washing waters are compared to obtain the maximum value and the minimum value among them, and the difference between the maximum value and the minimum value is used as the comparison result.

[0069] Further, as Figure 3 and 4 shown in the time-collection value experimental data curve graph, the horizontal axis is time and the vertical axis is the collection value, that is, the stain index. If within a set time period, its fluctuation around a certain collection value does not exceed the set range, then this collection value is used as a valid value. The acquisition of the stain index is stopped at the end stage of the washing process, and multiple valid values are compared to obtain the maximum value and the minimum value among them, and the difference between the maximum value and the minimum value is used as the comparison result. This ensures that the values of the maximum and minimum are not affected by accidental factors.

[0070] As another specific implementation manner of this embodiment, in step S1, the first stain index is obtained at the start stage of the current washing process, and the second stain index is obtained at the end stage of a washing process; in step S2, the first stain index and the second stain index are subtracted for comparison, and their difference is used as the comparison result. It is realized that the actual amount of dirt washed out during the current washing cycle can be obtained only through the difference between the stain indexes of two washing waters, ensuring the accuracy of the detection.

[0071] As another specific implementation manner of this embodiment, in step S1, during the current washing cycle, a first detection duration and a second detection duration are set. During the first detection duration and the second set duration, the washing device respectively obtains the stain indexes of at least two wash waters; in step S2, the average value of the stain indexes of at least two wash waters during the first detection duration is calculated to obtain a first average value, and the average value of the stain indexes of at least two wash waters during the second detection duration is calculated to obtain a second average value. By taking the difference between the first average value and the second average value for comparison, and taking the difference value as the comparison result. Through the difference between the first average value and the second average value, the accuracy of the actual amount of dirt washed out during the current washing cycle is further ensured. Further, the washing device obtains the stain index once every 2 seconds, takes the first half of the washing process as the first detection duration, and the average value of the stain indexes during the first detection duration is recorded as the first average value. The second half of the washing process is taken as the second detection duration, and the average value of the stain indexes during the second detection duration is recorded as the second average value.

[0072] In this embodiment, step S3 includes: setting a decreasing difference upper limit, a difference lower limit, and a washing completion lower limit in sequence; if the difference is greater than the difference upper limit, the water inlet flow rate intensity of the next washing process is adjusted to the weak water flow gear; if the difference is less than the difference lower limit and greater than the washing completion lower limit, the water inlet flow rate intensity of the next washing process is adjusted to the strong water flow gear; if the difference is less than or equal to the difference upper limit and greater than or equal to the difference lower limit, the water inlet flow rate intensity gear of the next washing cycle is set to be the same as that of the current washing cycle. It realizes adjusting the water inlet flow rate intensity gear of the next washing process according to the comparison result of the stain indexes of at least two wash waters during the current washing process, and ensures an appropriate water inlet flow rate intensity.

[0073] In this embodiment, step S3 includes: the rotation of the washing tub includes the rotation-stop duration ratio of the washing tub, and the rotation-stop duration ratio of the washing tub is the ratio of the duration of one rotation of the washing tub to the duration of stopping rotating after this rotation; setting the standard water flow gear of the water flow intensity; setting the rotation-stop duration ratio of the washing tub corresponding to the weak water flow gear to be less than the rotation-stop duration ratio of the washing tub corresponding to the standard water flow gear; setting the rotation-stop duration ratio of the washing tub corresponding to the strong water flow gear to be greater than the rotation-stop duration ratio of the washing tub corresponding to the standard water flow gear. It ensures that the water inlet flow rate intensity and the rotation-stop duration ratio of the washing tub are matched while conforming to the actual dirt degree of the clothes, realizes that the clothes are washed clean and the water inlet flow does not damage the clothes, and better meets the washing needs of users.

[0074] In this embodiment, before the next washing process of the washing device, the number of times exceeding the upper limit with the cumulative difference greater than the upper limit of the difference and the number of times exceeding the lower limit with the cumulative difference less than the lower limit of the difference and greater than the lower limit of cleanliness are counted; the rotation of the washing tub further includes the motor speed of the rotation of the washing tub; the ratio of the rotation and stop duration of the washing tub corresponding to the extremely weak water flow gear is set to be less than that of the weak water flow gear; the ratio of the rotation and stop duration of the washing tub corresponding to the extremely strong water flow gear is set to be greater than that of the strong water flow gear; the motor speed of the washing tub corresponding to the weak water flow gear is set to be less than that of the standard water flow gear; the motor speed corresponding to the extremely strong water flow gear is set to be greater than that of the strong water flow gear; if the number of times exceeding the upper limit reaches the first upper limit of the number of times, the water flow intensity of the next washing process is adjusted to the extremely weak water flow gear; if the number of times exceeding the lower limit reaches the first lower limit of the number of times, the water flow intensity of the next washing process is adjusted to the extremely strong water flow gear. Specifically, the first upper limit of the number of times and the first lower limit of the number of times are preferably 1 time.

[0075] When it is still detected that the actual amount of dirt washed out is relatively large or small after multiple washing processes, the water flow gear of the inlet water is further adjusted, so that the water flow intensity of the inlet water, the ratio of the rotation and stop duration of the washing tub, and the motor speed are matched while conforming to the actual dirt degree of the clothes, realizing that the clothes are washed clean and the inlet water flow does not damage the clothes, and better meeting the washing needs of users.

[0076] In this embodiment, a second upper limit of the number of times greater than the first upper limit of the number of times and a second lower limit of the number of times greater than the first lower limit of the number of times are set; if the number of times exceeding the upper limit reaches the second upper limit of the number of times, a reminder is sent to the user to reduce the dosing ratio of the laundry treatment agent in the next washing process, and the water flow intensity of the inlet water, the ratio of the rotation and stop duration of the washing tub, and the motor speed in the next washing process are adjusted to the standard gear; if the number of times exceeding the lower limit reaches the second lower limit of the number of times, a request message for whether to execute the next washing process is sent to the user, and the execution of the next washing process is stopped before receiving the instruction to execute the next washing process. Specifically, the second upper limit of the number of times and the second lower limit of the number of times are preferably 2 times, and more preferably two consecutive times, or two consecutive times are judged as the extremely weak water flow gear or the extremely strong water flow gear.

[0077] When there is dirt that cannot be washed clean through multiple washing cycles, such as color - fading clothes or excessive addition of detergent, a reminder is sent to the user, and the water inlet flow intensity, the rotation - stop duration ratio of the washing tub, and the motor speed of the next washing cycle are adjusted to further ensure that the water inlet flow intensity, the rotation - stop duration ratio of the washing tub, and the motor speed are in line with the actual dirt degree of the clothes, which is green and environmentally friendly. Also, when there are clothes that are detected as not dirty through multiple washing cycles, a request message asking whether to execute the next washing cycle is sent to the user to confirm whether the clothes are indeed not dirty and whether the clothes need to be washed further to be cleaner, further meeting the user's washing needs and being green and environmentally friendly.

[0078] In this embodiment, as Figures 1 to 4 shown, the specific process of the washing equipment system is as follows: The washing equipment and the mobile device are communicatively connected. The user sets the washing program, the preset water level value, and the water inlet flow intensity gear that need to be executed for the clothes to be washed this time through the washing equipment or the mobile device. During each washing process, steps S1, S2, and S3 are executed, and each washing process can be 30 seconds or 60 seconds.

[0079] In step S1, the control module of the washing equipment obtains two or more stain indices of the optical detection module. For example, the stain index value at the end of water inlet at the beginning stage of the washing process is used as the first stain index, and the stain index value before the start of drainage at the end stage of the washing process is used as the second stain index.

[0080] In step S2, the difference between the maximum or minimum value of multiple stain indices during the washing process is used as the comparison result, or the difference between the first stain index and the second stain index is used as the comparison result. Or, the difference between the first average value of the first detection duration and the second average value of the second detection duration is used as the comparison result.

[0081] In step S3, the difference in step S2 is compared with the upper limit and the lower limit of the difference, and the number of times the difference is greater than the upper limit of the difference and the number of times the difference is less than the lower limit of the difference are accumulated, including: the upper limit of the difference is preferably 2, the lower limit of the difference is preferably 0.5, and the lower limit of washing is preferably 0.2. If the difference is greater than the upper limit of the difference once, it indicates that the amount of dirt washed out this time is too large and the incoming water flow is too strong, which will wear the clothes. Then, the incoming water flow intensity of the next washing process is adjusted to the weak water flow gear. If the difference in the washing process after adjusting to the weak water flow gear is still greater than the upper limit of the difference, that is, the difference in two consecutive washing processes is greater than the upper limit of the difference, it indicates that the water flow is still too strong. Then, the incoming water flow intensity of the next washing process is adjusted to the extremely weak water flow gear. If the difference in the washing process after adjusting to the extremely weak water flow gear is still greater than the upper limit of the difference, that is, the difference in three consecutive washing processes is greater than the upper limit of the difference, it indicates that there is dirt that cannot be washed clean through multiple washing processes, such as clothes that fade and excessive detergent added. A reminder of "The clothes may fade" and "The detergent dosage has been automatically reduced" is sent to the user, and the incoming water flow intensity of the next washing process is adjusted to the standard water flow gear. If the washing device is a model with automatic dosing of fabric treatment agent, on the basis of the dosing ratio of the fabric treatment agent and the water level in the current washing process, the dosing ratio of the next washing process is reduced by 10% compared with the current one. Among them, according to the gear of the set water level, different values are set for the rotation-stop duration ratio and the motor speed of the washing tub corresponding to the standard water flow gear. For example, when the gear of the set water level is 1, the rotation-stop duration ratio of the washing tub corresponding to the standard water flow gear is 0.8 seconds to 0.6 seconds, and the motor speed is 630 rpm (Revolutions Per minute). The weak water flow gear is to subtract 0.2 seconds from the rotation duration of the rotation-stop duration ratio of the standard water flow gear corresponding to the gear of the set water level. For example, when the gear of the set water level is 1, the weak water flow gear adjusts the rotation-stop duration ratio to 0.6 seconds to 0.6 seconds. The extremely weak water flow gear is to subtract 0.2 seconds from the rotation duration of the rotation-stop duration ratio of the standard water flow gear corresponding to the gear of the set water level and add 0.1 second to the stop duration, and subtract 20 rpm from the motor speed. For example, when the gear of the set water level is 1, the extremely weak water flow gear adjusts the rotation-stop duration ratio to 0.6 seconds to 0.7 seconds, and the motor speed is adjusted to 610 rpm;

[0082] If the difference is less than the lower limit of the difference and greater than the lower limit of cleanliness once, it indicates that the amount of dirt washed out this time is too small and the incoming water flow is too weak, and the clothes will not be washed clean. Then, adjust the incoming water flow intensity of the next washing process to the strong water flow gear. If the difference in the washing process after adjusting to the strong water flow gear is still less than the lower limit of the difference and greater than the lower limit of cleanliness, that is, the differences in two consecutive washing processes are less than the lower limit of the difference and greater than the lower limit of cleanliness, it indicates that the water flow is still too weak. Then, adjust the incoming water flow intensity of the next washing process to the extremely strong water flow gear. If the difference in the washing process after adjusting to the extremely strong water flow gear is still less than the lower limit of the difference and greater than the lower limit of cleanliness, that is, the differences in three consecutive washing processes are greater than the upper limit of the difference, it indicates that there are clothes that are detected as not dirty through multiple washing processes. Then, send a request message to the user asking whether to execute the next washing process. Before the user confirms through the washing device or the mobile device that they need to continue washing, that is, before the washing device receives the instruction to execute the next washing process, stop the execution of the next washing process. Among them, the strong water flow gear is to add 0.2 seconds to the rotation duration of the rotation-stop duration ratio of the standard water flow gear corresponding to the set water level gear. For example, if the set water level gear is 1, the strong water flow gear will adjust the rotation-stop duration ratio to 1 second to 0.6 seconds. The extremely strong water flow gear is to add 0.2 seconds to the rotation duration of the rotation-stop duration ratio of the standard water flow gear corresponding to the set water level gear and increase the motor speed by 30 rpm. For example, if the set water level gear is 1, the extremely strong water flow gear will adjust the rotation-stop duration ratio to 1 second to 0.6 seconds and adjust the motor speed to 650 rpm;

[0083] If the difference in the current washing process is less than or equal to the upper limit of the difference and greater than or equal to the lower limit of the difference, it indicates that the amount of dirt washed out is moderate, and the incoming water flow intensity, the rotation-stop duration ratio of the washing tub, and the motor speed do not damage the clothes and can wash the clothes clean. Then, the incoming water flow intensity gear of the next washing process remains the same as this time, or is adjusted to the standard water flow gear;

[0084] If the difference in the current washing process is less than or equal to the lower limit of cleanliness, then enter the rinsing process, and rinse the residual laundry treatment agent on the clothes during the rinsing process;

[0085] At the same time in the above process, set the maximum washing time Tmax. The maximum washing time Tmax is preferably 30 minutes. If the running duration of the washing process exceeds the maximum washing time Tmax, then enter the rinsing process.

[0086] Further, by comparing the difference with the upper limit and lower limit of the difference, other washing methods can also be adjusted. Other washing methods include, for example, the time interval between two washing processes, the stop duration between two rotations of the washing tub, whether to add fabric softener, etc. Specifically, when the difference is greater than the upper limit of the difference, the time interval and the stop duration are increased, and the addition of fabric softener is reduced or stopped; when the difference is less than the lower limit of the difference and greater than the lower limit of cleanliness, the time interval and the stop duration are reduced, and the addition of fabric softener is increased or started; when the difference is equal to the upper limit of the difference and greater than or equal to the lower limit of the difference, the time interval, the stop duration, and the amount of fabric softener added are kept unchanged;

[0087] Furthermore, by obtaining the brand and type of the laundry treatment agent used by the user through a mobile device or a washing device, determining whether the laundry treatment agent is a laundry detergent pod, laundry liquid, or laundry powder, and whether the laundry detergent pod, laundry liquid, or laundry powder of this brand is a softening type, the amount of the laundry treatment agent and the amount of fabric softener added are further set.

[0088] In this embodiment, based on the comparison result of the stain indices of at least two washing waters in the current washing process, the water inlet flow rate and the rotation of the washing tub in the next washing process are adjusted, so that the rotation of the washing tub and the water inlet flow rate are matched while conforming to the actual dirtiness of the clothes, achieving the cleaning of the clothes without damaging the clothes by the water inlet flow, and better meeting the washing needs of the user.

[0089] Embodiment 2

[0090] As Figures 1 to 4 shown, this embodiment provides a washing equipment system, including: a washing module for washing clothes; an optical detection module for detecting the stain index in the washing module; a control module communicatively connected to the optical detection module for receiving the stain index of the optical detection module and adjusting the water inlet flow rate and the rotation of the washing tub in the next washing process of the washing module according to the stain index.

[0091] In this embodiment, the washing equipment system includes a washing device and a mobile device; the washing device sends reminder and request messages to the user and receives an instruction to execute the next washing process; and / or, after receiving the signal from the washing device, the mobile device sends reminder and request messages to the user, and after receiving the instruction to execute the next washing process, sends a signal to the washing device.

[0092] By receiving the signal of the washing device through the washing device and / or the mobile device, it is realized that the user can more conveniently receive reminder and request messages.

[0093] The washing module includes at least a washing tub and a motor for controlling the rotation of the washing tub.

[0094] The optical detection module includes optical sensors such as a near-infrared spectrum sensor or an ultraviolet spectrum sensor that can detect the stain index in water.

[0095] Specifically, the stain index is a feedback variable obtained by detecting through optical sensor modules such as a near-infrared spectrum sensor and an ultraviolet spectrum sensor, preferably obtained through an ultraviolet spectrum sensor module. Further, the ultraviolet spectrum sensor uses ultraviolet absorption spectrometry to detect the stain index. Ultraviolet absorption spectrometry detects the stain index through the corresponding relationship between a substance and its ultraviolet-visible spectroscopy (UV-VIS) when the substance absorbs light of a specific wavelength to reach its maximum value. The electromagnetic wave wavelength corresponding to the ultraviolet spectrum sensor is shorter and has greater energy, which can penetrate tiny bubbles and has a better response to micron-sized particles. The stain index includes various substances that cannot be detected by conventional sensors. The conventional sensors such as infrared pair tube sensors cannot detect organic soluble stains, including oily stains, proteins, fabric softeners, and emulsions, etc. While the ultraviolet spectrum sensor can detect the above-mentioned organic soluble stains and can also detect insoluble particulate matter. Among them, the protein in the organic soluble stain includes sweat stains. Therefore, the ultraviolet spectrum sensor can better detect the stain index in water including the amount of sweat stains while having a larger detection range.

[0096] Further, the band of sweat stains in the ultraviolet-visible spectrum is compared and analyzed with the spectral band of the detected stain index in the ultraviolet-visible spectrum, so as to obtain a more accurate stain index of the dirt.

[0097] The control module includes a Central Processing Unit (CPU), a general-purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), etc. The general-purpose processor can be a microprocessor or any conventional processor, etc. The logical judgment executed by the processing module can be completed by a hardware processor or by a combination of hardware and software modules in the processor.

[0098] In this embodiment, the communication connection can also be an electrical coupling or a direct coupling between modules. The communication connection can be wired communication, such as serial communication, or wireless communication, such as Bluetooth, WIFI (Wireless Fidelity) network, infrared communication, etc.

[0099] In this embodiment, the storage module is used to store Figure 3Based on the data in and the data of the stain index, the control module can call the data stored in the storage module to generate a curve as shown in Figure 4 and output it to the screen of the mobile device, enabling the user to more intuitively observe the changes in the stain index.

[0100] As a specific implementation, when the storage module is a Read-Only Memory (ROM) or a Random Access Memory (RAM), it can be built into the central processing unit, general-purpose processor, or digital signal processor of the processing module.

[0101] As another specific implementation, the storage module is applied to an external storage unit expanded by the processing module, and the storage module can interact or communicate with the processing module.

[0102] In this embodiment, the control module is further configured to, when no clothes are placed in the washing module, receive the stain index collected by the optical detection module, store multiple stain indices as historical data in the storage module, establish a stain index reference value based on the historical data, and correct the stain index collected by the optical detection module when clothes are placed in the washing module according to the stain index reference value.

[0103] This realizes the elimination of the influence of the stain index of the tap water used by the washing equipment on the detection result.

[0104] In this embodiment, the mobile device is specifically a smart device with communication functions, such as a smart phone, a smart voice speaker, a smart remote control screen, etc. When the feedback module includes a mobile device, the mobile device pushes feedback to the user or outputs information through voice broadcast.

[0105] As a specific implementation, the control module is applied to the controller of the washing equipment, and the controller and the mobile device are communicatively connected via WIFI or Bluetooth, achieving the method described in the first embodiment at a relatively low cost.
