DETAILED DESCRIPTION

[0065] In the description of the present invention, it should be noted that the terms "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0066] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0067] One of the technical problems with washing water treatment in the related art is that the removal of impurities and dirt from the washing water is generally done through multiple rounds of water changes. However, multiple rounds of water changes not only cause waste of washing water but also fail to further optimize the water quality of the washing water.

[0068] The second technical problem with washing water treatment in the related art is that during the washing process, fabrics with low color fastness are more likely to fade, resulting in color bleeding. However, current washing equipment is difficult to separate and filter the colored dyes in the washing water, resulting in color bleeding during the washing process.

[0069] Based on the above problems, the following embodiments are proposed:

[0070] Example 1

[0071] Combine Figure 1A washing water treatment device includes: a filter chamber 2 for accommodating washing water to be treated; a drain outlet 8, which is arranged at the top end of the filter chamber 2; a decontamination processor 3, which is installed at the bottom end of the filter chamber 2, and the decontamination processor 3 includes a bubble generator 301 and an air conveyor 302; a controller, which is configured to control the air conveyor 302 to input air outside the filter chamber 2 into the bubble generator 301 to form bubbles in the washing water to be treated in the filter chamber 2.

[0072] In this embodiment, the air conveyor 302 is an air compressor. Through the operation of the air compressor, external air can be continuously pressed into the bubble generator 301. The bubble generator 301 is a pipeline with a plurality of fine air outlet structures. After the compressed air is ejected through the fine air outlet, tiny bubbles are formed. When the buoyancy of the bubbles in the water is greater than the tension between the bubbles and the bubble generator 301, the bubbles float up. During the floating process of the bubbles, impurities and dirt in the washing water can be carried to the top of the liquid surface, thereby achieving the optimization of the water quality of the washing water. The setting of the washing water treatment device can relatively reduce the number of times the washing water is replaced during the washing process, thereby achieving a water-saving effect. In one scenario, the impurities in the washing water are fine impurities, for example, pigment impurities in the washing water. The use of the embodiment of the present application can reduce or remove pigment impurities in the washing water, which is beneficial to improve the anti-color cross-linking effect when the washing water is used for washing again.

[0073] The diameter of the air outlet of the bubble generator 301 is 0.44 mm to 0.56 mm. The limitation of the diameter of the air outlet makes it difficult for the air outlet to be blocked, and the air outlet can generate dense tiny bubbles.

[0074] The production and size of bubbles determine the aeration filtration efficiency of the filter chamber 2. For example, larger impurity particles such as hair and dust in the water can be removed with bubbles of about 1.5mm to 2.5mm, while smaller impurity particles can be removed with micro bubbles of less than 0.5mm. Since the diameter of the air outlet on the bubble generator 301 is fixed, the size of the bubbles generated can be determined by the air flow rate of the air compressor. When the aperture is fixed, the air flow rate of the air compressor can be changed to adjust the bubble size, thereby making the aeration filtration of the filter chamber 2 suitable for filtering different impurities.

[0075] like Figure 1 As shown, optionally, in one implementation of this embodiment, the controller is also configured to control the air conveyor 302 and the bubble generator 301 so that the bubbles are discharged from the drain port 8. As the number of bubbles continues to increase, the bubble height continues to rise until it rises to the drain port 8 and is discharged. The bubbles bring out impurities together. Discharging impurities in this way is more convenient than removing bubbles from the liquid surface, thereby simplifying the overall structure of the washing water treatment device.

[0076] like Figure 1 As shown, optionally, in one implementation of this embodiment, the impurity removal processor 3 also includes an oxidizing molecule generator, which is arranged at the air inlet of the gas conveyor 302; the controller is configured to control the oxidizing molecule generator to increase the oxidizing molecule content in the air input to the bubble generator 301 by the gas conveyor 302.

[0077] In this embodiment, the oxidizing molecule generator is an ionization generator, which is controlled by a controller to produce oxidizing molecules by operating the ionization generator, thereby effectively increasing the content of oxidizing molecules in the air pressed into the bubble generator 301 by the air conveyor 302. The bubbles generated by the bubble generator 301 have a higher content of oxidizing molecules. The increase in the content of oxidizing molecules can not only achieve a better sterilization effect, but also oxidize the dye pigment molecules dissolved in the washing water. The dye pigment is a relatively small impurity and can be removed by micro-bubbles below 0.5 mm. That is, the washing water treatment device can not only remove impurities, but also remove dye pigments in the washing water, which can effectively prevent the washed items from being colored in the washing water.

[0078] like Figure 1 As shown, optionally, in one implementation of this embodiment, the impurity removal processor 3 also includes a vibrator 303, and the vibrator 303 is connected to the bubble generator 301; the controller is configured to control the vibration frequency of the vibrator 303, and the bubbles on the bubble generator 301 are vibrated off into the washing water to be processed through the vibration of the vibrator 303.

[0079] In this embodiment, the connection between the vibrator 303 and the bubble generator 301 is rigid, so the vibration generated by the vibrator 303 will be transmitted to the bubble generator 301.

[0080] When the aperture of the bubble generator 301 is fixed, changing the air flow rate of the air compressor can adjust the bubble diameter within a certain range, but the limited adjustment range makes it difficult to accurately control the bubble diameter. Therefore, the bubble generator 301 is designed to be combined with the vibrator 303. Through mechanical vibration, the separation time of the bubbles and the bubble generator 301 is changed, and the air flow rate of the air compressor is controlled to control the bubble diameter and density. Therefore, the aeration filtration efficiency of the filter chamber 2 can be dynamically adjusted according to the amount and type of impurities.

[0081] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0082] A partition 4 is provided in the filter chamber 2, which divides the filter chamber 2 into a first chamber 201 and a second chamber 202. The top of the partition 4 is located lower than the drain outlet 8.

[0083] A washing water inlet is provided at the bottom of the first chamber 201, and a clean water outlet is provided on the side wall of the second chamber 202, which belongs to the filter chamber 2. The clean water outlet is lower than the top position of the partition 4, or the clean water outlet is lower than the top position of the partition 4 and the distance from the bottom of the second chamber 202 exceeds the set distance.

[0084] In this embodiment, the washing water to be treated enters the first chamber 201 through the washing water inlet, and gradually rises upward from the bottom of the first chamber 201. After the aeration process, the bubbles in the washing water float up. During the floating process of the bubbles, the fine impurities, dye pigment impurities, etc. in the washing water are carried to the top of the liquid surface and discharged from the drain outlet 8. The liquid level of the purified washing water in the first chamber 201 rises to the top of the partition 4, passes over the top of the partition 4, enters the second chamber 202, and is discharged from the clean water outlet. Preferably, the clean water outlet is set at a position between the top position of the partition 4 and the bottom position of the second chamber 202. This position reserves a certain height for the sedimentation of clean water in the second chamber 202. The bottom of the second chamber 202 serves as a sedimentation bin. The impurities in the washing water in the second chamber 202 settle to its bottom under the action of gravity, further improving the overall filtration efficiency of the filter bin 2.

[0085] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0086] A liquid level detector 9 is provided at the top of the first chamber 201; the height of the bubbles in the first chamber 201 is the bubble height, and the controller is configured to obtain the bubble height detected by the liquid level detector 9 and control the amount of air input by the air delivery machine 302 according to the bubble height.

[0087] The liquid level detector 9 is a liquid level probe. The liquid level detector 9 detects the bubble height. When the detected foam height is less than the preset height value, it proves that the current filtration efficiency is low and the bubble density needs to be increased. At this time, the bubble height value can be increased by increasing the air compressor frequency. When the detected foam height is equal to or greater than the preset height value, it proves that the current filtration efficiency is normal and there is no need to change the bubble density. At this time, the bubble height can be maintained unchanged by keeping the air compressor frequency unchanged.

[0088] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0089] A turbidity detector 10 and a color detector 11 are provided at the purified water outlet;

[0090] The controller is configured to obtain the turbidity value of the purified water flowing out of the second chamber 202 detected by the turbidity detector 10 , and to obtain the color gamut value of the purified water flowing out of the second chamber 202 detected by the color detector 11 .

[0091] Traditionally, a single turbidity sensor is used to detect the transmittance of water, but it is unable to identify whether the decrease in turbidity of the water is due to dust or stains in the object being cleaned, or due to discoloration of the object being cleaned. In this embodiment, a turbidity sensor 10 and a color detector 11 are provided at the clean water outlet to distinguish between discoloration and conventional impurities. Specifically, the turbidity value of the washing water is obtained by the turbidity detector 10, and the turbidity value is converted into a voltage value. The controller can determine whether the water is turbid by comparing the voltage value with the preset voltage value. If it is relatively turbid, the color range value of the washing water is obtained by the color detector 11. The controller can determine whether there is discoloration by comparing the color range value with the preset color range value, thereby providing a basis for the working mode of the impurity removal processor 3.

[0092] Example 2

[0093] A washing machine is provided, comprising:

[0094] A washing tub 1 for washing, and a washing water treatment device of embodiment 1, wherein the washing tub 1 is fluidically connected to the washing water treatment device to form a first flow path for washing water to flow from the washing tub 1 into the washing water treatment device, and a second flow path for washing water to flow from the washing water treatment device into the washing tub 1.

[0095] like Figure 1 As shown, in the washing machine of this embodiment, the washing tub 1 is used in conjunction with the washing water treatment device to circulate and filter the washing water in the washing tub. The washing water in the washing tub 1 flows into the washing water treatment device through a first flow path. After being filtered by the washing water treatment device, the purified washing water flows back to the washing tub 1 through a second flow path. Thus, the washing water treatment device can circulate and filter the washing water in the washing tub 1 to remove impurities and color from the washing water.

[0096] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0097] The washing tub 1 has a top position and a bottom position which are in the same direction as the filter bin 2 after installation;

[0098] The bottom end of the washing tub 1 is connected to the bottom end of the filter bin 2 via a first connecting pipe 5, forming a first flow path;

[0099] The upper portion of the bottom end of the filter bin 2 is connected to the upper portion of the bottom end of the washing tub 1 via a second connecting pipe 6, forming a second flow path;

[0100] A water pump 7 is provided on the first connecting pipe 5 , and the water pump 7 is configured to allow the washing water in the washing tub 1 to flow into the filter bin 2 through a first flow path and to flow out of the filter bin 2 into the washing tub 1 through a second flow path.

[0101] Under the pumping force of the water pump 7, the washing water in the washing tub 1 enters the filter bin 2 through the first flow path, and gradually rises upward from the bottom of the filter bin 2. After the aeration process, the bubbles in the washing water float up. During the floating process, the fine impurities, dye pigment impurities, etc. in the washing water are carried to the top of the liquid surface and can be discharged from the drain port 8 at the top of the filter bin 2. The clean water part flows out of the filter bin 2 through the second flow path and returns to the washing tub 1 to continue washing. The bottom of the filter bin 2 serves as a sedimentation bin, and the impurities in the washing water in the filter bin 2 are settled to its bottom under the action of gravity.

[0102] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0103] A partition 4 is provided in the filter bin 2, which divides the filter bin 2 into a first chamber 201 and a second chamber 202. A washing water inlet is provided at the bottom of the first chamber 201 to form a first flow path, and a clean water outlet is provided on the side wall of the second chamber 202 belonging to the filter bin 2 to form a second flow path.

[0104] Under the action of the pumping force of the water pump 7, the washing water in the washing tub 1 enters the first chamber 201 through the first flow path, and gradually rises upward from the bottom of the first chamber 201. After the aeration process, the bubbles in the washing water float up. During the floating process, the fine impurities, dye pigment impurities, etc. in the washing water are carried to the top of the liquid surface and discharged from the drain outlet 8. The level of the purified washing water in the first chamber 201 rises to the top of the partition 4, passes over the top of the partition 4, enters the second chamber 202, and is discharged to the washing tub 1 from the clean water outlet. The bottom of the second chamber 202 serves as a sedimentation bin. The impurities in the washing water in the second chamber 202 settle to its bottom under the action of gravity, further improving the overall filtration efficiency of the filter bin 2.

[0105] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0106] The second connecting pipe 6 is provided with a turbidity detector 10 and a color detector 11 for detecting the turbidity value and color range value of the clean water flowing out of the washing water in the second flow path, and sending the detection results of the turbidity value and color range value to the controller.

[0107] By arranging a turbidity sensor 10 and a color detector 11 in the second connecting pipe 6, it is possible to distinguish between discoloration and conventional impurities. Specifically, the turbidity value of the washing water is obtained by the turbidity detector 10, and the turbidity value is converted into a voltage value. The controller can determine whether the water is turbid by comparing the voltage value with the preset voltage value. If it is relatively turbid, the color range value of the washing water is obtained by the color detector 11. The controller can determine whether there is discoloration by comparing the color range value with the preset color range value, thereby providing a basis for the working mode of the impurity removal processor 3.

[0108] Example 3

[0109] This embodiment provides a washing water treatment method, combined with Figure 3 ,

[0110] The washing water treatment method is applied to the washing water treatment device of Example 1 and is executed by the controller. The washing water treatment method includes an anti-color cross-linking treatment process. The anti-color cross-linking treatment process includes: during the operation of the gas conveyor 302, the gas flow rate of the gas conveyor 302 is controlled according to the height of the bubbles formed in the filter chamber 2.

[0111] In this embodiment, the air delivery device 302 is an air compressor. Through the operation of the air compressor, external air is continuously pressed into the bubble generator 301. The bubble generator 301 is a pipeline with a plurality of fine air outlets. After the compressed air is ejected through the fine air outlets, tiny bubbles are formed. When the buoyancy of the bubbles in the water is greater than the tension between the bubbles and the bubble generator 301, the bubbles float upward. During the rising process, the bubbles can carry fine impurities in the washing water, such as pigment impurities in the washing water, to the top of the liquid surface. As the number of bubbles continues to increase, the bubble height continues to rise until it reaches the drain outlet 8 and is discharged, thereby preventing color bleeding of the washed items in the washing water.

[0112] The diameter of the air outlet of the bubble generator 301 is 0.44 mm to 0.56 mm. The limitation of the diameter of the air outlet makes it difficult for the air outlet to be blocked, and the air outlet can generate dense tiny bubbles.

[0113] The production and size of bubbles determine the aeration filtration efficiency of the filter chamber 2. For example, larger impurity particles such as hair and dust in water can be removed with bubbles of about 1.5mm to 2.5mm, while dark-colored dyes can be removed with micro-bubbles of less than 0.5mm. Since the diameter of the air outlet on the bubble generator 301 is fixed, the size of the bubbles generated can be determined by the air flow rate of the air compressor. When the aperture is fixed, the air flow rate of the air compressor can be changed to adjust the bubble size, thereby making the aeration filtration of the filter chamber 2 suitable for filtering different impurities.

[0114] Optionally, in one implementation of this embodiment, Figure 3 ,

[0115] The gas transmission machine 302 is an air compressor;

[0116] The gas flow rate of the gas conveyor 302 is controlled according to the bubble height of the bubbles formed in the filter chamber 2, including:

[0117] Get the bubble height value. If the bubble height value is less than the preset bubble height value, control the air compressor operating frequency to C1; otherwise, control the air compressor operating frequency to C2.

[0118] Among them, C1>C2.

[0119] The control method of changing the bubble diameter by controlling the frequency of the air compressor is relatively simple, direct and effective.

[0120] In this embodiment, the washing water to be treated enters the first chamber 201 through the washing water inlet, and gradually rises upward from the bottom of the first chamber 201. After the aeration process, the bubbles in the washing water float up. During the floating process of the bubbles, the fine impurities, dye pigment impurities, etc. in the washing water are carried to the top of the liquid surface and discharged from the drain outlet 8. The liquid level detector 9 can be a liquid level sensor for detecting the bubble height in the first chamber 201. The bubble height is detected by the liquid level detector 9. The filtration efficiency in the current state can be judged according to the obtained bubble height value. When the detected foam height is less than the preset height value, it proves that the current filtration efficiency is low and it is necessary to increase the bubble density. At this time, the bubble height can be increased by increasing the compressor frequency. When the detected foam height is equal to or greater than the preset height value, it proves that the current filtration efficiency is normal and there is no need to change the bubble density. At this time, the bubble height can be maintained unchanged by keeping the compressor frequency unchanged.

[0121] Optionally, in one implementation of this embodiment, Figure 3 ,

[0122] The washing water treatment device includes a vibrator 303 controlled by a controller, and the vibrator 303 is connected to the bubble generator 301;

[0123] The anti-color cross-linking process also includes:

[0124] Obtaining a turbidity detection value, which is used to characterize the turbidity of the washing water after being treated by the washing water treatment device,

[0125] Adjusting the vibration frequency of the vibrator 303 according to the turbidity value interval to which the turbidity detection value belongs;

[0126] The higher the turbidity value, the higher the vibration frequency of the vibrator corresponding to the turbidity value interval, or,

[0127] The turbidity value interval includes a first turbidity value interval, a second turbidity value interval and a third turbidity value interval. When the turbidity detection value is within the first turbidity value interval, the vibration frequency of the vibrator 303 is controlled to be V1. When the turbidity detection value is within the second turbidity value interval, the vibration frequency of the vibrator 303 is controlled to be V2. When the turbidity detection value is within the third turbidity value interval, the vibration frequency of the vibrator 303 is controlled to be V3. Among them, the first turbidity value interval < the first turbidity value interval < the third turbidity value interval, and the relationship satisfied by V1~V3 is V1<V2<V3.

[0128] Control the vibrator 303 to vibrate the bubbles on the bubble generator 301 and remove them.

[0129] In this embodiment, the bubbles are detached into the washing water in a vibration manner, and the size of the bubbles can be further accurately controlled by controlling the vibration frequency, changing the separation time of the bubbles and the bubble generator 301, and controlling the air flow rate of the air compressor to control the bubble size and density, thereby dynamically adjusting the aeration filtration efficiency of the filter bin 2 according to the amount and type of impurities.

[0130] A turbidity sensor detects the turbidity of the wash water, determines the degree of discoloration based on the turbidity, and controls the bubble size accordingly, adjusting the efficiency of filtration to remove color from the wash water. When the turbidity is between D2.0 and D2.5, the vibration frequency is adjusted to V1.0, so that the bubble diameter falls within a first range, making the bubble size suitable for filtering the color of the wash water. When the turbidity is between D2.5 and D3.0, the vibration frequency is adjusted to V2.0, so that the bubble diameter falls within a second range, making the bubble size suitable for filtering the color of the wash water. When the turbidity is between D3.0 and D3.5, the vibration frequency is adjusted to V3.0, so that the bubble diameter falls within a third range, making the bubble size suitable for filtering the color of the wash water. Changing the bubble diameter by controlling the vibration frequency of the vibrator is relatively simple, direct, and effective.

[0131] Optionally, in one implementation of this embodiment,

[0132] The washing water treatment device includes an oxidizing molecule generator controlled by a controller. The oxidizing molecule generator is located at the air inlet of the air conveyor 302. The anti-color cross-linking treatment process also includes:

[0133] Before obtaining turbidity measurements, turn on the oxidizing molecule generator.

[0134] The oxidizing molecule generator is an ionization generator, which is controlled by a controller to produce oxidizing molecules, effectively increasing the oxygen content in the air pressed into the bubble generator 301 by the air conveyor 302. The bubbles generated by the bubble generator 301 have a higher oxidizing molecule content. The increase in the oxidizing molecule content can oxidize the dye pigment molecules dissolved in the washing water. The increase in the oxidizing molecule content can not only achieve a better sterilization effect, but also oxidize the dye pigment molecules dissolved in the washing water. The dye pigment is a relatively small impurity and can be removed by micro bubbles below 0.5 mm, effectively preventing the washed items from bleeding into the washing water.

[0135] Optionally, in one implementation of this embodiment, Figure 2 ,

[0136] The washing water treatment method also includes: an anti-color cross-talk judgment process, which includes:

[0137] Obtaining a turbidity detection value and a color gamut detection value, wherein the turbidity detection value and the color gamut detection value are respectively used to characterize the turbidity and color of the washing water after being treated by the washing water treatment device;

[0138] When the turbidity detection value is greater than the preset turbidity value and the color gamut detection value is greater than the preset color gamut value, it is determined that the anti-cross-color processing flow needs to be executed.

[0139] Specifically, if the turbidity value is greater than a preset value, the color gamut value is obtained;

[0140] If the color gamut value is greater than the color preset value, the anti-cross-color processing process will be entered; if the color gamut value is less than or equal to the color preset value, the normal processing process will be entered;

[0141] If the turbidity value is less than or equal to, the normal processing flow is entered.

[0142] Compared with the traditional method of detecting the transmittance of water bodies through a single turbidity value, it is impossible to identify whether the decrease in turbidity of water bodies is due to dust and stains in the cleaned object, or due to discoloration of the cleaned object. In this embodiment, through the progressive detection of turbidity values ​​and color gamut values, it is possible to distinguish between discoloration and conventional impurities. First, the obtained turbidity value is used to determine whether the water body is turbid. If it is relatively turbid, the obtained color gamut value, that is, the color gamut value, is used to determine whether there is discoloration. Specifically, through the RGB color gamut value detected by the color detector, if any R / G / B value is greater than 100, it is considered that the water contains dye pigments, and the anti-color cross-linking processing process is entered. If or when the R / G / B values ​​are all less than or equal to 100, the conventional processing process is entered.

[0143] Optionally, in one implementation of this embodiment, Figure 2 ,

[0144] The wash water treatment method also includes:

[0145] When the turbidity value is less than or equal to the preset turbidity value, or when the color range value is less than or equal to the preset color range value, the normal processing flow is entered;

[0146] The general processing flow includes:

[0147] The gas transmission machine 302 is an air compressor;

[0148] Get the bubble height value. If the bubble height value is less than the preset bubble height value, control the air compressor operating frequency to C1; otherwise, control the air compressor operating frequency to C2.

[0149] Among them, C1>C2.

[0150] The washing water treatment device includes a vibrator 303 controlled by a controller, and the vibrator 303 is connected to the bubble generator 301;

[0151] Adjusting the vibration frequency of the vibrator 303 according to the turbidity value interval to which the turbidity detection value belongs;

[0152] The higher the turbidity value, the higher the vibration frequency of the vibrator corresponding to the turbidity value interval, or,

[0153] The turbidity value interval includes a first turbidity value interval, a second turbidity value interval and a third turbidity value interval. If the turbidity value is within the first turbidity value interval, the vibration frequency of the vibrator 303 is controlled to be V 1， When the turbidity value is within the second turbidity value interval, the vibration frequency of the vibrator 303 is controlled to be V2. When the turbidity value is within the third turbidity value interval, the vibration frequency of the vibrator 303 is controlled to be V3. Among them, the first turbidity value interval < the first turbidity value interval < the third turbidity value interval, and the relationship satisfied by V1~V3 is V1<V2<V3.

[0154] The difference between the conventional treatment process and the anti-color cross-linking treatment process is that in the conventional treatment process, the oxidizing molecule generator is not in a working state.

[0155] Example 4

[0156] like Figure 2 、 3 As shown, the washing water treatment method provided in this embodiment is applied to the washing machine in the second embodiment and is executed by the controller. A water pump 7 is provided on the first flow path. The washing water treatment method includes:

[0157] In response to a water cleaning instruction, the water pump 7 is activated to allow washing water to flow from the washing tub 1 of the washing machine into the washing water treatment device via the first flow path and to flow back into the washing tub 1 via the washing water treatment device and the second flow path;

[0158] Start the gas transmission machine 302 and execute the washing water treatment method in embodiment 3.

[0159] As shown in Figures 5 and 6, the details are as follows:

[0160] During the washing stage, the turbidity value of the washing water is obtained;

[0161] If the turbidity value is less than or equal to the preset value D2.0, the normal processing flow is entered.

[0162] If the turbidity value is greater than the preset value, the color gamut value is obtained;

[0163] The color gamut value is the RGB color gamut value. If any value of R / G / B is greater than 100, it is considered that the water contains dye pigments, and the anti-color cross-linking treatment process is entered. If the R / G / B values ​​are all less than or equal to 100, the normal treatment process is entered.

[0164] Enter the anti-color cross-talk process:

[0165] When the turbidity value is within the first turbidity preset range, the bubble diameter is controlled to be within the first range; when the turbidity value is within the second turbidity preset range, the bubble diameter is controlled to be within the second range; when the turbidity value is within the third turbidity preset range, the bubble diameter is controlled to be within the third range;

[0166] When the turbidity value is in the range of D2.0 to D2.5, the vibration frequency is adjusted to V1.0 so that the bubble diameter is within the first range, so that the bubble size at this time is suitable for filtering the color of the current washing water; when the turbidity value is in the range of D2.5 to D3.0, the vibration frequency is adjusted to V2.0 so that the bubble diameter is within the second range, so that the bubble size at this time is suitable for filtering the color of the current washing water; when the turbidity value is in the range of D3.0 to D3.5, the vibration frequency is adjusted to V3.0 so that the bubble diameter is within the third range, so that the bubble size at this time is suitable for filtering the color of the current washing water, V1.0<V2.0<V3.0;

[0167] Get the bubble height value. If the bubble height value is less than the preset height value H0, increase the bubble density. If the bubble height value is greater than or equal to the preset height value H0, keep the current bubble density unchanged.

[0168] The bubble height is detected by the liquid level detector 9, and the filtration efficiency in the current state can be judged based on the obtained bubble height value. When the detected foam height is less than the preset height value, it proves that the current filtration efficiency is low and it is necessary to increase the bubble density. At this time, the bubble height can be increased by increasing the compressor frequency. When the detected foam height is equal to or greater than the preset height value, it proves that the current filtration efficiency is normal and there is no need to change the bubble density. At this time, the bubble height can be maintained unchanged by keeping the compressor frequency unchanged.

[0169] Increasing bubble density involves controlling air delivery machine 302, i.e., the air compressor frequency, to C1. Maintaining the current bubble density involves controlling air delivery machine 302, i.e., the air compressor frequency, to C2, where C1 > C2. Changing bubble diameter by controlling the air compressor frequency is a relatively simple, direct, and effective method.

[0170] In summary, the ingenious design of the cleaning device in the above embodiment lies in:

[0171] First, the air compressor works to continuously pressurize external air into the bubble generator. After the compressed air is ejected through the bubble generator, tiny bubbles are formed. During the floating process of the bubbles, the tiny impurities in the washing water can be carried to the top of the liquid surface. The device also has a vibrator. By changing the air compressor flow and the vibration frequency of the vibrator, the size of the generated bubbles can be changed, thereby changing the aeration filtration efficiency of the filter bin, making the filter bin aeration filtration suitable for filtering to remove different impurities.

[0172] Secondly, the controller controls the ionization generator to produce oxidizing molecules, effectively increasing the content of oxidizing molecules in the air pressed into the bubble generator by the air conveyor. The bubbles produced by the bubble generator have a higher content of oxidizing molecules. The increase in the content of oxidizing molecules can oxidize the dye pigment molecules dissolved in the washing water, thereby further preventing the clean objects in the washing water from bleeding.

[0173] Second, the bubble height in the filter chamber is detected by a liquid level detector. When the detected foam height is less than the preset height value, it proves that the current filtration efficiency is low and the bubble density needs to be increased. At this time, the bubble height can be increased by increasing the compressor frequency. When the detected foam height is equal to or greater than the preset height value, it proves that the current filtration efficiency is normal and there is no need to change the bubble density. At this time, the bubble height can be maintained unchanged by keeping the compressor frequency unchanged. This design enables the filter chamber to maintain a high-efficiency filtration state.

[0174] Third, by setting up a turbidity sensor in combination with a color detector, it is possible to distinguish between discoloration and conventional impurities. By obtaining the turbidity value of the water body through the turbidity detector, it can be determined whether the water body is turbid. If it is relatively turbid, the color range value of the water body is obtained through the color detector. The controller can determine whether there is discoloration by comparing the color range value with the preset color range value, providing a basis for the working mode of the impurity removal processor.
