Description
Technical Field
The invention relates to the technical field of intelligent household appliances, in particular to a detergent throwing control method, a detergent throwing control device, a storage medium and washing equipment.
Background
Before washing laundry using a washing machine, it is necessary to deliver a detergent to the washing machine. Typically, the administration of the detergent is done by a person based on experience, which mainly includes the more clothes, the more detergent is administered. However, even in the case of application experience, the amount of the detergent to be manually administered is not completely stable, and the detergent is easily administered too much or too little. When the detergent is excessively put, the condition that the detergent on the clothes is difficult to rinse is easily caused, namely, a lot of residual detergent is remained on the clothes when the washing is finished; or to the expense of water and electricity due to the need for multiple rinses. When the detergent is put too little, stains on clothes are easy to be cleaned.
Some washing machines have a function of automatically putting in detergent, and users only need to put more detergent in the storage box, and before the clothes are filled with water, the washing machine determines the amount of detergent to be put in according to the weight of the clothes in the drum, and finishes putting in the detergent. This input approach can have certain advantages over manual approaches, but still has significant limitations:
1) The weight of the items in the drum is not necessarily the actual weight of the laundry, and the laundry may already have detergent on it. For example, users often manually wash clothes that are stained and dirty, and difficult to clean by a washing machine, before using the washing machine, so that the clothes placed in the washing machine have detergent and water thereon, which results in the washing machine significantly overestimating the weight of the clothes and adding too much detergent.
2) The water absorbency of different garments varies. The amount of detergent determined in the prior art is the same for the same weight of laundry. However, laundry (e.g., cotton-padded clothes, down jackets, etc.) having high water absorbency generally requires more water to be put in, so that the concentration of detergent in the water is low when the laundry is washed; clothing with weak water absorption (such as silk and hemp, chemical fiber and the like) needs to be put with smaller water quantity, so that the concentration of the detergent in the water is higher.
Therefore, how to enable a washing machine to adaptively and accurately deliver a proper amount of washing agent is a technical problem to be solved in the art.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present invention.
Example 1
Fig. 1 shows a flowchart of a detergent delivery control method, and as shown in fig. 1, the detergent delivery control method provided in this embodiment may be applied to a washing device, and includes:
Step S101, injecting water according to the initial water injection amount and adding the detergent according to the first adding amount, obtaining a first-stage water injection amount when the water amount in the washing equipment reaches a target water level, and obtaining a first equilibrium concentration when the detergent reaches a concentration equilibrium state in the operation process of the washing equipment.
In some implementations, before step S101, further includes:
step S100a, the weight of the articles to be washed in the washing equipment and the target concentration corresponding to the current washing mode are obtained.
In practical application, the washing device may be a washing machine, the detergent is stored in the storage box, and is put into the washing device through water flushing, the weight of the articles to be washed in the washing device can be measured by a sensor arranged in the washing device, such as a gravity sensor, and the weight of the articles to be washed in the washing device comprises the sum of the weight of dry clothes, the weight of the water existing on the clothes and the weight of the detergent.
In one example, the weight of the article to be washed is obtained by detecting a first weight when the inner tub of the washing apparatus is empty and a second weight after the laundry is placed in the inner tub, and then calculating a difference between the second weight and the first weight.
In some implementations, a corresponding relation between a washing mode and a target concentration is preset, a user selects the set target washing mode as a current washing mode before starting the washing machine, and then the corresponding target concentration is determined, wherein the washing mode can be, for example, down jackets, silks, cotton-flax, jeans and the like, the concentration requirements of different washing modes on the washing agent can be different, and the method adaptively calculates the first adding amount and adding increment of the washing agent based on the target concentration corresponding to the current washing mode, so that the concentration requirements of different washing modes can be met, and intelligent washing is realized.
Step S100b, determining an initial water injection amount according to the weight of the articles to be washed.
In some implementations, the initial water injection amount is a preset multiple M of the weight of the items to be washed, the preset multiple M being determined according to the current washing pattern. The water quantity requirements of different washing modes may be different, and in this embodiment, the corresponding relationship between the washing mode and the preset multiple M, the target concentration, the target water level and other parameters is predetermined, so that the corresponding initial water injection quantity can be determined according to the current washing mode, and the initial water injection quantity basically meets the target concentration requirement.
Step S100c, determining the first-time adding amount of the detergent according to the initial water injection amount and the target concentration.
After the initial water injection amount and the first-time injection amount are determined, the first stage is entered, and water injection with the initial water injection amount and detergent injection with the first-time injection amount are started.
In practical application, the injected water amount and the injected detergent amount can be obtained through a flow sensor or a gravity sensor, and the method can be realized through the prior art, and the details of the embodiment are omitted.
In the first stage, when the initial water injection amount is insufficient to reach the target water level (for example, the water level in the washing equipment is too low or too low due to the strong water absorption of the clothes), a proper amount of clean water is continuously injected based on the initial water injection amount to complete the water injection process of the first stage. Thus, in some implementations, obtaining a first stage water injection rate when the water level within the washing apparatus reaches a target water level includes:
After the initial water injection amount is injected, if the water amount in the washing equipment does not reach the target water level, continuing to inject water until the water amount in the washing equipment reaches the target water level, and obtaining the first-stage water injection amount, wherein the first-stage water injection amount comprises the initial water injection amount and the water amount for continuing to inject water.
It should be understood that after the initial water injection amount is injected, if the water amount in the washing device reaches the target water level, the water injection is not required to be continued, and the obtained first-stage water injection amount includes the initial water injection amount.
In the first stage, if the detergent reaches a concentration balance state during the operation of the washing equipment, the concentration at the moment is the first balance concentration, and the first stage is ended.
In practice, after the detergent and the clean water are injected into the washing equipment, the detergent is dissolved into the water uniformly and gradually along with the washing process of the washing equipment, the concentration change of the detergent in the water is gradually increased until the balance (namely, the maximum value appears), so that the concentration change of the detergent in the water can be continuously monitored by using a concentration sensor, the change rate of the concentration of the detergent, namely, the increase value or the decrease value of the concentration of the detergent in unit time, is calculated, and when the change rate is close to 0, the concentration of the detergent in the water reaches the balance state.
In the case that the first equilibrium concentration is obtained, it is further necessary to determine whether the first equilibrium concentration reaches the target concentration, and if the first equilibrium concentration reaches the target concentration, it is not necessary to perform a subsequent step, and the detergent is completely dosed. And when the first equilibrium concentration is smaller than the target concentration, the second stage is needed to be entered, and water is injected again to enable the detergent concentration to reach the equilibrium state again, so that the detergent feeding increment is calculated.
And step S102, determining a second-stage water injection amount according to the first-stage water injection amount and injecting water of the second-stage water injection amount under the condition that the first equilibrium concentration is smaller than the target concentration, and acquiring a second equilibrium concentration when the detergent reaches a concentration equilibrium state in the running process of the washing equipment.
In some implementations, the second stage injection rate is in a fixed, preset ratio relationship with the first stage injection rate.
In some cases, the preset ratio is denoted by R, and the fixed preset ratio R may be determined according to the measurement error rate of the concentration sensor for detecting the concentration of the detergent and is greater than the measurement error rate, but cannot be too large, and the excessive preset ratio R may cause an increase in the water consumption of the washing and the detergent consumption, resulting in waste of resources, and degradation of the washing experience and the intelligent experience. Accordingly, the preset ratio R may take a value 3 to 5 times the measured error rate, for example, when the measured error rate is 2%, the preset ratio R may be set to 10%. And after the clean water of the water injection quantity of the second stage is injected, when the detergent reaches a concentration balance state in the running process of the washing equipment, obtaining a second balance concentration.
And step 103, calculating a throwing increment and throwing the corresponding throwing increment of the detergent according to the first equilibrium concentration, the second equilibrium concentration, the first-stage water injection quantity, the second-stage water injection quantity and the first throwing quantity so that the equilibrium concentration of the detergent reaching a concentration equilibrium state in the running process of the washing equipment is not less than the target concentration.
In some cases, the purity of the detergent may be obtained by a sensor provided to the washing apparatus for detecting the purity of the detergent. Correspondingly, according to the first equilibrium concentration, the second equilibrium concentration, the first stage water injection quantity, the second stage water injection quantity and the first throwing quantity, the throwing increment is calculated and the throwing increment of the detergent is thrown, and the method comprises the following steps:
step S103-a1, obtaining the purity of the detergent.
Specifically, the purity of the detergent detected by the sensor is obtained.
Step S103-a2, calculating a throwing increment by using the first calculation formula and throwing the detergent of the throwing increment.
The first calculation formula is as follows:
ΔC≈((W0+W1+C1+W2+Wc)*Dg-(A0+CC*C1))/CC
Wherein Δc represents a delivery increment, W 0 represents the weight of water existing on the laundry before starting the washing apparatus, W 1 represents a first-stage water injection amount, C 1 represents a first-stage water injection amount, W 2 represents a second-stage water injection amount, D g represents a target concentration, a 0 represents the dry weight of detergent existing on the laundry before starting the washing apparatus, C C represents the purity of the detergent, and W c represents a preset water injection amount required when the detergent of the delivery increment is delivered.
W 0、A0 is obtained based on the first equation and the second equation through simultaneous solving;
the first equation is: (A) 0+CC*C1)/(W0+W1+C1)＝D1
The second equation is: (A) 0+CC*C1)/(W0+W1+C1+W2)＝D2
Where D 1 represents a first equilibrium concentration and D 2 represents a second equilibrium concentration.
In the first calculation above, (W 0+W1+C1+W2+Wc)*Dg represents the target net dosage of detergent required to reach the target concentration, and (A 0+CC*C1) represents the actual net dosage of detergent. It will be appreciated that the net dosage of detergent is part of the detergent due to the presence of water in the detergent.
In this embodiment, the equilibrium concentration may be obtained by injecting water in the first stage and the second stage and reaching the equilibrium state twice, the first equation and the second equation are established, and the unknown quantity W 0、A0 may be easily obtained by solving the two equations simultaneously. On one hand, no corresponding device is required to detect the two unknowns, and the cost is obviously increased; on the other hand, even if cost issues are not considered, it is difficult to accurately quantify these two unknowns by the device. By means of the solving mode of the embodiment, the unknown quantity can be automatically solved in the relevant process of water injection and detergent throwing, the throwing increment of the detergent is automatically calculated based on the known quantities (including the solved unknown quantity), the efficient automatic throwing process is achieved, human intervention is not needed, the concentration of the detergent in the throwing increment reaches an equilibrium state as soon as possible, the washing effect and the washing experience are improved, the efficient automatic throwing of the detergent is achieved, and the throwing process of the detergent is accurate and reliable.
In other cases, the washing device is not provided with a sensor for detecting the purity of the detergent, so that the purity of the detergent cannot be directly obtained through the sensor, the third equation can be established by adding the water injection in the third stage and reaching the equilibrium state of the detergent again, the unknown quantity W 0、A0 can be solved, the purity C C of the detergent can be solved by combining the third equation with the first equation and the second equation established in the first two stages, and the purity C C of the detergent can be known even if no device is used for detecting the purity, so that the detergent can be automatically fed in with high efficiency. Correspondingly, according to the first equilibrium concentration, the second equilibrium concentration, the first stage water injection quantity, the second stage water injection quantity and the first throwing quantity, the throwing increment is calculated and the throwing increment of the detergent is thrown, and the method comprises the following steps:
Step S103-b1, determining a third-stage water injection amount according to the second-stage water injection amount, and injecting water of the third-stage water injection amount, and obtaining a third equilibrium concentration when the detergent reaches a concentration equilibrium state in the running process of the washing equipment.
In some implementations, the third stage injection rate is in a fixed, preset ratio relationship with the second stage injection rate.
In some cases, the preset ratio is denoted by T, where the preset ratio T may be determined according to the measurement error rate of the concentration sensor for detecting the concentration of the detergent, and is greater than the measurement error rate, but cannot be too large, and an excessive preset ratio T may cause an increase in the amount of water used for washing and the amount of detergent, resulting in waste of resources, and degradation of washing experience and intelligentized experience. Therefore, the preset ratio T may take a value 2 to 3 times the measured error rate, for example, when the measured error rate is 2%, the preset ratio T may be set to 4%. And after the clean water with the water injection quantity in the third stage is injected, when the detergent reaches a concentration balance state in the running process of the washing equipment, obtaining the third balance concentration.
The following three equations can be established through the three stages, so that the unknown quantity required for calculating the addition amount of the detergent is solved, and the addition amount is calculated by using the second calculation formula. It should be understood that the water injection quantity of the three stages is gradually reduced, so that the waste of resources caused by overlarge water consumption and detergent consumption in washing can be effectively avoided, the automation of detergent delivery can be realized by small adjustment of the detergent and the water injection quantity, the target concentration is quickly reached, and the efficiency of detergent delivery is improved.
The first equation is: (A) 0+CC*C1)/(W0+W1+C1)＝D1
The second equation is: (A) 0+CC*C1)/(W0+W1+C1+W2)＝D2
The third equation is ：(A0+CC*C1)/(W0+W1+C1+W2+W3)＝D3
Wherein W 0 represents the weight of water existing on clothes before the washing equipment is started, W 1 represents the first-stage water injection amount, C 1 represents the first-time injection amount, W 2 represents the second-stage water injection amount, W 3 represents the third-stage water injection amount, D g represents the target concentration, A 0 represents the dry weight of detergent existing on clothes before the washing equipment is started, C C represents the purity of the detergent, and D 3 represents the third equilibrium concentration.
Step S103-b2, solving the first equation, the second equation and the third party Cheng Lianli to obtain the purity C C of the detergent, the dry weight A 0 of the detergent existing on the clothes before the washing equipment is started and the weight W 0 of the water existing on the clothes before the washing equipment is started. Thus, the quantities to the right of the equation in the second calculation formula are all known.
And step S103-b3, calculating a throwing increment by using a second calculation formula and throwing the detergent of the throwing increment.
The second calculation formula is as follows:
ΔC≈((W0+W1+C1+W2+W3+Wc)*Dg-(A0+CC*C1))/CC
Wherein, deltaC represents the throwing increment, and W c represents the preset water injection quantity required when the detergent of the throwing increment is thrown. It will be appreciated that the detergent is stored in the storage box and is delivered into the washing apparatus by water flushing, so that the predetermined amount of water required for flushing the detergent is a known amount of water.
Parameters involved in the calculation of the detergent dosage increment are shown in table 1:
TABLE 1 parameters involved in detergent dosage increment calculation
In some implementations, the method of this embodiment further includes:
The solved purity of the detergent C C was recorded for subsequent use.
Specifically, when intelligent dosing of the detergent is performed next time, if the same detergent is used, the purity C C of the detergent can be directly called, so that the unknown quantity W 0、A0 is solved based on the related parameters of the first stage and the second stage, the dosing increment is calculated, and the steps S103-a1 to S103-a2 are executed. Thus, the third stage is prevented from being executed again, and the time cost of throwing and the waste of water resources are increased.
In determining whether to use the same detergent (whether to directly call/acquire purity of detergent C C to calculate the dosing increment), this can be accomplished by a user confirming information of whether to update a new detergent. Specifically, in practical applications, when the user sets the washing mode of the washing apparatus, a confirmation interface for whether to replace the new detergent is generated for the user to select and confirm, if the user selects to replace the new detergent, the calculation of the delivery increment is performed according to the flow of steps S103-b1 to S103-b3, and if the user selects to not replace the new detergent, the calculation of the delivery increment is performed according to the flow of steps S103-a1 to S103-a 2. By the arrangement, the efficiency of detergent throwing can be further improved.
It should be appreciated that since the dosage increment of the detergent is much smaller relative to the total weight of material in the washing apparatus, the first and second calculations ignore the effect of the dosage increment of the detergent on the total weight of material in the washing apparatus.
In the method of the embodiment, when the washing equipment firstly injects clean water, the detergent with the first dosage is put in, and then the detergent increment to be further put in is calculated by monitoring the concentration change of the detergent in the water, so that the intelligent putting of the detergent can be realized.
Example two
Fig. 2 shows a schematic diagram of a detergent delivery control device, and as shown in fig. 2, the detergent delivery control device provided in this embodiment includes:
a first injection module 201, configured to inject water with an initial water injection amount and inject detergent with a first injection amount, obtain a first stage water injection amount when the water amount in the washing device reaches a target water level, and obtain a first equilibrium concentration when the detergent reaches a concentration equilibrium state during operation of the washing device;
the second delivery module 202 is configured to determine a second-stage water injection amount according to the first-stage water injection amount and inject water of the second-stage water injection amount when the first equilibrium concentration is less than the target concentration, and obtain a second equilibrium concentration when the detergent reaches a concentration equilibrium state during operation of the washing apparatus;
And the increment calculating module 203 is configured to calculate a delivery increment according to the first equilibrium concentration, the second equilibrium concentration, the first stage water injection amount, the second stage water injection amount, and the first delivery amount when the second equilibrium concentration is less than the target concentration, and deliver the detergent in the delivery increment so that the equilibrium concentration of the detergent is not less than the target concentration when the detergent reaches the concentration equilibrium state during operation of the washing apparatus.
In some implementations, the apparatus of this embodiment further includes:
the initial determining module is used for acquiring the weight of the articles to be washed in the washing equipment and the target concentration corresponding to the current washing mode; determining an initial water injection amount according to the weight of the articles to be washed; and determining the first-time adding amount of the detergent according to the initial water injection amount and the target concentration.
In some implementations, the initial water injection amount is a preset multiple M of the weight of the items to be washed, the preset multiple M being determined according to the current washing pattern. The water quantity requirements of different washing modes may be different, and in this embodiment, the corresponding relationship between the washing mode and the preset multiple M, the target concentration, the target water level and other parameters is predetermined, so that the corresponding initial water injection quantity can be determined according to the current washing mode, and the initial water injection quantity basically meets the target concentration requirement.
In the first stage, when the initial water injection amount is insufficient to reach the target water level (for example, the water level in the washing equipment is too low or too low due to the strong water absorption of the clothes), a proper amount of clean water is continuously injected based on the initial water injection amount to complete the water injection process of the first stage. Thus, in some implementations, obtaining a first stage water injection rate when the water level within the washing apparatus reaches a target water level includes:
After the initial water injection amount is injected, if the water amount in the washing equipment does not reach the target water level, continuing to inject water until the water amount in the washing equipment reaches the target water level, and obtaining the first-stage water injection amount, wherein the first-stage water injection amount comprises the initial water injection amount and the water amount for continuing to inject water.
It should be understood that after the initial water injection amount is injected, if the water amount in the washing device reaches the target water level, the water injection is not required to be continued, and the obtained first-stage water injection amount includes the initial water injection amount.
In some implementations, the second stage injection rate is in a fixed, preset ratio relationship with the first stage injection rate.
In some cases, the preset ratio is denoted by R, where the preset ratio R may be determined according to a measurement error rate of a concentration sensor for detecting the concentration of the detergent and is greater than the measurement error rate, but cannot be too large, and an excessive preset ratio R may cause an increase in the amount of water used for washing and the amount of detergent, resulting in waste of resources, and degradation of washing experience and intelligent experience. Accordingly, the preset ratio R may take a value 3 to 5 times the measured error rate, for example, when the measured error rate is 2%, the preset ratio R may be set to 10%. And after the clean water of the water injection quantity of the second stage is injected, when the detergent reaches a concentration balance state in the running process of the washing equipment, obtaining a second balance concentration.
In some cases, the purity of the detergent may be obtained by a sensor provided to the washing apparatus for detecting the purity of the detergent. Correspondingly, according to the first equilibrium concentration, the second equilibrium concentration, the first stage water injection quantity, the second stage water injection quantity and the first throwing quantity, the throwing increment is calculated and the throwing increment of the detergent is thrown, and the method comprises the following steps: the purity of the detergent is obtained, and the addition amount is calculated by using the first calculation formula and the detergent of the addition amount is added.
The first calculation formula is as follows:
ΔC≈((W0+W1+C1+W2+Wc)*Dg-(A0+CC*C1))/CC
Wherein Δc represents a delivery increment, W 0 represents the weight of water existing on the laundry before starting the washing apparatus, W 1 represents a first-stage water injection amount, C 1 represents a first-stage water injection amount, W 2 represents a second-stage water injection amount, D g represents a target concentration, a 0 represents the dry weight of detergent existing on the laundry before starting the washing apparatus, C C represents the purity of the detergent, and W c represents a preset water injection amount required when the detergent of the delivery increment is delivered.
W 0、A0 is obtained based on the first equation and the second equation through simultaneous solving;
the first equation is: (A) 0+CC*C1)/(W0+W1+C1)＝D1
The second equation is: (A) 0+CC*C1)/(W0+W1+C1+W2)＝D2
Where D 1 represents a first equilibrium concentration and D 2 represents a second equilibrium concentration.
In this embodiment, the equilibrium concentration may be obtained by injecting water in the first stage and the second stage and reaching the equilibrium state twice, the first equation and the second equation are established, and the unknown quantity W 0、A0 may be easily obtained by solving the two equations simultaneously. On one hand, no corresponding device is required to detect the two unknowns, and the cost is obviously increased; on the other hand, even if cost issues are not considered, it is difficult to accurately quantify these two unknowns by the device. By means of the solving mode of the embodiment, the unknown quantity can be automatically solved in the relevant process of water injection and detergent throwing, the throwing increment of the detergent is automatically calculated based on the known quantities (including the solved unknown quantity), the efficient automatic throwing process is achieved, human intervention is not needed, the concentration of the detergent in the throwing increment reaches an equilibrium state as soon as possible, the washing effect and the washing experience are improved, the efficient automatic throwing of the detergent is achieved, and the throwing process of the detergent is accurate and reliable.
In other cases, the washing device is not provided with a sensor for detecting the purity of the detergent, so that the purity of the detergent cannot be directly obtained through the sensor, the third equation can be established by adding the water injection in the third stage and reaching the equilibrium state of the detergent again, the unknown quantity W 0、A0 can be solved, the purity C C of the detergent can be solved by combining the third equation with the first equation and the second equation established in the first two stages, and the purity C C of the detergent can be known even if no device is used for detecting the purity, so that the detergent can be automatically fed in with high efficiency. Correspondingly, according to the first equilibrium concentration, the second equilibrium concentration, the first stage water injection quantity, the second stage water injection quantity and the first throwing quantity, the throwing increment is calculated and the throwing increment of the detergent is thrown, and the method comprises the following steps:
Determining a third-stage water injection amount according to the second-stage water injection amount, injecting water of the third-stage water injection amount, and acquiring a third equilibrium concentration when the detergent reaches a concentration equilibrium state in the running process of the washing equipment; solving the first equation, the second equation and the third party Cheng Lianli to obtain the purity C C of the detergent, the dry weight A 0 of the detergent existing on the clothes before the washing equipment is started and the weight W 0 of the water existing on the clothes before the washing equipment is started; and calculating a delivery increment using the second calculation formula and delivering the detergent of the delivery increment.
In some implementations, the third stage injection rate is in a fixed, preset ratio relationship with the second stage injection rate.
In some cases, the preset ratio is denoted by T, where the preset ratio T may be determined according to the measurement error rate of the concentration sensor for detecting the concentration of the detergent, and is greater than the measurement error rate, but cannot be too large, and an excessive preset ratio T may cause an increase in the amount of water used for washing and the amount of detergent, resulting in waste of resources, and degradation of washing experience and intelligentized experience. Therefore, the preset ratio T may take a value 2 to 3 times the measured error rate, for example, when the measured error rate is 2%, the preset ratio T may be set to 4%. And after the clean water with the water injection quantity in the third stage is injected, when the detergent reaches a concentration balance state in the running process of the washing equipment, obtaining the third balance concentration.
The following three equations can be established through the three stages, so that the unknown quantity required for calculating the addition amount of the detergent is solved, and the addition amount is calculated by using the second calculation formula. It should be understood that the water injection quantity of the three stages is gradually reduced, so that the waste of resources caused by overlarge water consumption and detergent consumption in washing can be effectively avoided, the automation of detergent delivery can be realized by small adjustment of the detergent and the water injection quantity, the target concentration is quickly reached, and the efficiency of detergent delivery is improved.
The first equation is: (A) 0+CC*C1)/(W0+W1+C1)＝D1
The second equation is: (A) 0+CC*C1)/(W0+W1+C1+W2)＝D2
The third equation is ：(A0+CC*C1)/(W0+W1+C1+W2+W3)＝D3
Wherein W 0 represents the weight of water existing on clothes before the washing equipment is started, W 1 represents the first-stage water injection amount, C 1 represents the first-time injection amount, W 2 represents the second-stage water injection amount, W 3 represents the third-stage water injection amount, D g represents the target concentration, A 0 represents the dry weight of detergent existing on clothes before the washing equipment is started, C C represents the purity of the detergent, and D 3 represents the third equilibrium concentration.
