Fig. 1 shows a flowchart of a clothes weighing method of a washing machine according to an embodiment of the present application, where the clothes weighing method of the washing machine can be performed by the washing machine, it should be noted that the clothes weighing method of the washing machine in the embodiment is particularly suitable for a drum washing machine requiring intelligent weighing of clothes, and it can be understood that the drum washing machine can automatically set a washing time, a water inlet amount and a detergent input amount according to an intelligent weighing result of the clothes, thereby achieving automatic washing of the clothes. Referring to fig. 1, the laundry weighing method of the washing machine may include steps S110 to S140, as follows:

in step S110, in response to a control instruction for weighing the laundry in the inner drum of the washing machine, the motor of the washing machine is controlled to rotate, and the current detected dry laundry weight and the detected wet laundry weight of the inner drum of the washing machine are determined based on the load power of the motor of the washing machine during rotation, a pre-stored first corresponding relationship between the load power of the motor of the washing machine during rotation in a state without water ingress and the dry laundry weight placed in the inner drum of the washing machine calibrated in advance, and a pre-stored second corresponding relationship between the load power of the motor of the washing machine during rotation in a state without water ingress and the wet laundry weight placed in the inner drum of the washing machine calibrated in advance.

The washing machine inner drum is a space area used for washing clothes in the washing machine, and the control command is a command used for weighing the clothes in the washing machine inner drum. In an actual use scene, the control instruction may be a washing instruction for washing the laundry by the washing machine, or may be a special instruction for weighing the laundry in the inner drum of the washing machine. After receiving the control instruction, the washing machine controls the washing machine motor to rotate and detects the load power of the washing machine motor during rotation.

It can be understood that the control command may be a control command sent to the washing machine by a user through a remote control device or an intelligent terminal, or may be a control command triggered by the user when the user directly operates a virtual button or an entity key provided in the washing machine, which is not limited herein.

The load power of the motor of the washing machine during rotation has a relation with the weight of the clothes placed in the inner drum of the washing machine, and before the washing machine leaves a factory, a manufacturer of the washing machine calibrates the corresponding relation in advance and stores the calibrated corresponding relation in a local storage of the washing machine. Since the dry and wet states of the clothes in the inner drum of the washing machine affect the corresponding relationship, in order to ensure the accuracy of weighing and detecting the clothes in the inner drum of the washing machine, the corresponding relationship needs to be calibrated separately from the dry and wet states.

The washing machine prestores a first corresponding relation and a second corresponding relation which are calibrated in advance in a local storage, wherein the first corresponding relation is the corresponding relation between the load power of a washing machine motor during rotation and the weight of clothes placed in the washing machine inner barrel when the washing machine inner barrel is in a non-water inlet state. The second corresponding relation is the corresponding relation between the load power of the washing machine motor in rotation and the weight of the wet clothes placed in the washing machine inner barrel when the washing machine inner barrel is in a state of no water inlet.

Referring to fig. 2, fig. 2 shows a flowchart of a laundry weighing method of a washing machine according to an embodiment of the present application, and the laundry weighing method of a washing machine in the present embodiment may further include steps S210 to S240, which are described in detail as follows.

In step S210, in response to a control instruction for weighing the laundry in the drum of the washing machine, the rotation speed of the washing machine motor is controlled to rotate in order from low to high, and a plurality of load powers of the washing machine motor at different rotation speeds are detected.

After a control instruction for weighing the clothes in the inner drum of the washing machine is received, the rotating speed of the motor of the washing machine can be controlled to rotate from low to high in the state that the inner drum of the washing machine is not filled with water, and a plurality of load powers corresponding to the motor of the washing machine at different rotating speeds are detected.

Specifically, the washing machine motor may be rotated at a rotation speed V1 for a running time t1, and then the washing machine motor is controlled to increase to a rotation speed V2 at a certain acceleration, and the load power of the rotation speed of the washing machine motor between V1 and V2 is detected in the process of increasing to V2 from V1, thereby realizing detection of multiple load powers of the washing machine motor at different rotation speeds.

It can be understood that larger rotation speed grades of V3, V4 and the like can be set, so that the washing machine motor can conveniently detect a plurality of load powers of the washing machine motor at different rotation speeds within the rotation speed range reached by the washing machine motor.

In step S220, dry laundry weights and wet laundry weights corresponding to the plurality of load powers, respectively, are determined based on the plurality of load powers of the washing machine motor at different rotation speeds, the first correspondence relationship, and the second correspondence relationship, which are detected.

For a plurality of load powers of the detected washing machine motor under different rotating speeds, the dry clothes weight and the wet clothes weight corresponding to the plurality of load powers can be found out from the first corresponding relation and the second corresponding relation respectively.

In step S230, the dry laundry detection weight is determined based on an average of the dry laundry weights corresponding to the plurality of load powers, respectively.

After the dry-laundry weights corresponding to the plurality of load powers are obtained, the average value of the dry-laundry weights corresponding to the plurality of load powers may be used as the dry-laundry detection weight.

It can be understood that the average value can be determined after removing the larger value and the smaller value of the weight of the dry clothes corresponding to the plurality of load powers respectively, so as to improve the weighing accuracy of the clothes in the washing machine drum in a dry state.

In step S240, the wet laundry detection weight is determined based on an average value of the wet laundry weights corresponding to the plurality of load powers, respectively.

After the wet laundry weights corresponding to the plurality of load powers are obtained, an average value of the wet laundry weights corresponding to the plurality of load powers may be used as the wet laundry detection weight.

It will be appreciated that the average value may be determined after eliminating the greater and lesser values of the weight of the wet laundry corresponding to the respective plurality of load powers, so as to improve the accuracy of weighing the laundry in the drum of the washing machine in a wet condition.

In the technical solution of the embodiment shown in fig. 2, the load power of the motor of the washing machine within the range of the achievable rotating speed is detected, so as to avoid the condition that the load power of the motor of the washing machine is not accurately detected due to the clothes squeezing the door, and meanwhile, the accuracy of performing dry state weighing detection and wet state weighing detection on the clothes in the inner drum of the washing machine can be improved.

Referring to fig. 3, fig. 3 shows a flowchart of a laundry weighing method of a washing machine according to an embodiment of the present application, which may further include steps S310 to S320, as described in detail below.

In step S310, for dry clothes placed in the inner tub of the washing machine under different weights, the motor of the washing machine is controlled to rotate from low to high in a state without water intake, and a plurality of load powers of the motor of the washing machine under different rotation speeds are detected.

When the first corresponding relation between the load power of the motor of the washing machine and the weight of the dry clothes placed in the inner drum of the washing machine is calibrated under the condition that the inner drum of the washing machine is not in a water inlet state, the dry clothes with different weights can be sequentially placed in the inner drum of the washing machine. For example, dry clothes with increasing weight of 0.5KG can be put into the inner drum of the washing machine in sequence to realize the calibration of the first corresponding relation.

It can be understood that in order to improve the accuracy of weighing and detecting the laundry in the washing machine drum, dry laundry with a weight of 0.1KG may be sequentially put into the washing machine drum.

For dry clothes placed in the inner drum of the washing machine under different weights, the rotating speed of the motor of the washing machine is controlled to rotate from low to high in sequence under the state of no water inflow, and a plurality of load powers of the motor of the washing machine under different rotating speeds are detected.

Specifically, the washing machine motor may be rotated at a rotation speed V1 for a running time t1, and then the washing machine motor is controlled to increase to a rotation speed V2 at a certain acceleration, and the load power of the washing machine motor between V1 and V2 is detected in the process of increasing to V2 at the rotation speed V1, so as to detect a plurality of load powers of the washing machine motor at different rotation speeds.

It can be understood that larger rotation speed levels of V3, V4, etc. can be set to facilitate detection of multiple load powers of the washing machine motor at different rotation speeds within the range of rotation speeds that the washing machine motor can reach.

In step S320, an average value of the detected multiple load powers of the washing machine motor at different rotation speeds is associated with the weight of the placed dry clothes to generate a first corresponding relationship.

And calculating the average value of the plurality of load powers of the detected washing machine motor at different rotating speeds, and associating the average value with the weight of the placed dry clothes to generate a first corresponding relation. It will be appreciated that the average may also be determined after removing the larger and smaller of the plurality of load powers.

In the technical scheme of the embodiment shown in fig. 3, when the first corresponding relationship between the load power of the motor of the washing machine during rotation and the weight of the dry clothes placed in the inner drum of the washing machine is calibrated, the load power of the motor of the washing machine within the range of the achievable rotating speed is detected, so that the condition that the accuracy of calibrating the first corresponding relationship is reduced due to different rotating speeds of the motor of the washing machine can be avoided, and the accuracy of dry state weighing detection of the clothes in the inner drum of the washing machine is further improved to a certain extent.

Referring to fig. 4, fig. 4 shows a flowchart of a laundry weighing method of a washing machine according to an embodiment of the present application, and the laundry weighing method of a washing machine in the present embodiment may further include steps S410 to S420, which are described in detail as follows.

In step S410, for wet clothes placed in the inner tub of the washing machine under different weights, the motor of the washing machine is controlled to rotate from low to high in sequence under a state of no water inflow, and a plurality of load powers of the motor of the washing machine under different rotating speeds are detected.

When the second corresponding relation between the load power of the motor of the washing machine and the weight of the wet clothes placed in the inner drum of the washing machine is calibrated under the condition that the inner drum of the washing machine is not filled with water, the wet clothes with different weights placed in the inner drum of the washing machine can be placed in sequence. For example, wet clothes with weight increased by 0.5KG can be put into the inner drum of the washing machine in sequence to realize the calibration of the second corresponding relationship. It can be understood that in order to improve the accuracy of weighing and detecting the laundry in the inner tub of the washing machine, wet clothes with weight increased by 0.1KG can be sequentially put into the inner tub of the washing machine.

For wet clothes placed in the inner drum of the washing machine under different weights, the rotating speed of the motor of the washing machine is controlled to rotate from low to high in sequence under the state of no water inflow, and a plurality of load powers of the motor of the washing machine under different rotating speeds are detected.

In step S420, the average value of the detected plurality of load powers of the washing machine motor at different rotation speeds is associated with the weight of the placed wet laundry, and a second correspondence relationship is generated.

And calculating the average value of the plurality of load powers of the detected washing machine motor at different rotating speeds, and correlating the average value with the weight of the placed wet clothes to generate a second corresponding relation. It will be appreciated that the average may be determined after removing the larger and smaller of the plurality of load powers.

In the technical solution of the embodiment shown in fig. 4, when calibrating the second corresponding relationship between the load power of the motor of the washing machine during rotation and the weight of the wet laundry placed in the inner drum of the washing machine, by detecting the load power of the motor of the washing machine within the reachable rotating speed range, the situation that the accuracy of calibrating the second corresponding relationship is reduced due to different rotating speeds of the motor of the washing machine can be avoided, and the accuracy of weighing and detecting the wet state of the laundry in the inner drum of the washing machine is further improved to a certain extent.

Referring to fig. 1, in step S120, the water inlet valve is opened to allow water to enter the inner tub of the washing machine, and a first water inlet duration from the beginning of water inlet to the time when the water level of the inner tub reaches the first water level section is detected.

After determining the current dry and wet detection weights of the inner drum of the washing machine, in order to further determine whether the clothes placed in the inner drum of the washing machine are dry clothes or wet clothes, the water inlet valve can be opened to enable water in the water inlet pipeline to enter the inner drum of the washing machine. The first water level section is a preset water level section which can be reached in the inner drum of the washing machine, and the first water inlet time is the time from the beginning of water inlet to the time when the water level of the inner drum of the washing machine reaches the first water level section.

When the first water inlet time length is detected, specifically, a timer is started to time when water in the water inlet pipeline enters the inner barrel of the washing machine by starting the water inlet valve, the water level of the inner barrel of the washing machine is detected by the water level detection device, the time is stopped when the water level of the inner barrel of the washing machine reaches a preset basic water level section, and the time length of the timer is used as the first water inlet time length from the beginning of water inlet to the time when the water level of the inner barrel of the washing machine reaches the first water level section. The water level detection device can be a water level sensor, a flowmeter and the like, and can directly or indirectly measure the water level of the inner drum of the washing machine.

In step S130, a second water inlet duration is determined based on the detected weight of the dry clothes and a pre-stored third corresponding relationship, where the third corresponding relationship is a pre-calibrated corresponding relationship between the weight of the dry clothes placed in the inner drum of the washing machine in the water inlet state and the water inlet duration when the water level of the inner drum of the washing machine reaches the first water level section from the beginning of water inlet.

The third corresponding relation is the corresponding relation between the weight of the dry clothes placed in the inner barrel of the washing machine and the water inlet duration of the water level of the inner barrel of the washing machine from the beginning of water inlet to the first water level section in the water inlet state. After determining the current detected weight of dry laundry and the detected weight of wet laundry in the inner drum of the washing machine, in order to further determine whether the laundry placed in the inner drum of the washing machine is dry laundry or wet laundry, a second water inlet duration may be determined according to the detected weight of dry laundry and a pre-stored third corresponding relationship, and by comparing the first water inlet duration with the second water inlet duration, it is determined whether the laundry placed in the inner drum of the washing machine is dry laundry or wet laundry according to a size relationship between the first water inlet duration and the second water inlet duration.

Optionally, when the third corresponding relationship is calibrated, dry clothes with different weights may be sequentially placed in the inner drum of the washing machine, and the water inlet duration from the beginning of water inlet to the time when the water level of the inner drum of the washing machine reaches the first water level section is detected, so as to generate the third corresponding relationship.

Specifically, the clothes with the weight increased by 0.5KG can be sequentially put into the inner barrel of the washing machine, so that the first corresponding relation is calibrated. It can be understood that in order to improve the accuracy of weighing and detecting the clothes in the inner drum of the washing machine, dry clothes with the weight increased by 0.1KG can be sequentially put into the inner drum of the washing machine.

Referring to fig. 5, fig. 5 shows a flowchart of a laundry weighing method of a washing machine according to an embodiment of the present application, the third corresponding relationship includes a plurality of third corresponding relationships at different water inlet pressures, and before step S120, the laundry weighing method of a washing machine in the embodiment may further include steps S510 to S520, which are described in detail as follows.

In step S510, a water inlet valve is opened to allow water to enter the washing machine tub, and a third water inlet time period from the beginning of water inlet to the time when the water level in the washing machine tub reaches a predetermined basic water level section is detected.

The third corresponding relation comprises a third corresponding relation that the pipelines of the washing machine are respectively calibrated at different water inlet pressures. The third corresponding relation under the water pressure of the inlet water is calibrated, the water pressure of the inlet water of the washing machine pipeline is determined, dry clothes with different weights are placed in the inner drum of the washing machine in sequence, and the third corresponding relation under the water pressure of the inlet water is generated by detecting the water inlet time of the water level of the inner drum of the washing machine from the beginning of water inlet to the time when the water level reaches the first water level section. Repeating the above modes, and sequentially calibrating the third corresponding relation of the washing machine under other water inlet pressures.

When the current water inlet pressure of the washing machine pipeline is detected, the water inlet valve can be opened to enable water to enter the washing machine outer barrel, and the third water inlet time length from the beginning of water inlet to the time when the water level in the washing machine outer barrel reaches the preset basic water level section is detected. The preset basic water level section is a preset water level section which can be reached in the outer drum of the washing machine. It is understood that the water pressure of the inlet water can be detected by a water pressure sensor.

When the third water inlet time length is detected, specifically, a timer is started to time when the water in the water inlet pipeline enters the outer barrel of the washing machine by starting the water inlet valve, the water level of the outer barrel of the washing machine is detected by the water level detection device, the time is stopped when the water level of the outer barrel of the washing machine reaches a preset basic water level section, and the time length of the timer is used as the third water inlet time length from the beginning of water inlet to the time when the water level of the outer barrel of the washing machine reaches the preset basic water level section.

In step S520, the current water inlet pressure of the washing machine is determined based on the third water inlet duration and a pre-stored fourth corresponding relationship, where the fourth corresponding relationship is a pre-calibrated corresponding relationship between the water inlet pressure of the washing machine and the water inlet duration from the beginning of water inlet to the time when the water level of the outer tub of the washing machine reaches the predetermined basic water level section.

The fourth corresponding relation is the corresponding relation between the water inlet pressure of the washing machine calibrated in advance and the water inlet time length from the beginning of water inlet to the time when the water level of the outer drum of the washing machine reaches the preset basic water level section.

Optionally, when the fourth corresponding relationship is calibrated, different water inlet pressures may be sequentially set, and according to the set water inlet pressure, the water inlet duration of the water level of the outer drum of the washing machine from the beginning of water inlet to the time when the water level reaches the predetermined basic water level section is detected, so as to generate the fourth corresponding relationship, and store the fourth corresponding relationship in the local storage of the washing machine.

After the third water inlet time period is determined, the current water inlet pressure of the washing machine may be determined based on the third water inlet time period and the pre-stored fourth corresponding relationship.

In this embodiment, step S130 may specifically include: determining a third corresponding relation corresponding to the current water inlet pressure based on the current water inlet pressure and a plurality of third corresponding relations under different water inlet pressures; and determining a second water inlet duration based on the detected weight of the dry clothes and a third corresponding relation corresponding to the current water inlet pressure.

After determining the current water pressure of the washing machine, a third corresponding relationship corresponding to the current water pressure of the water may be determined among a plurality of third corresponding relationships under different water pressures of the water based on the current water pressure of the water. And determining a second water inlet duration based on a third corresponding relation corresponding to the current water inlet pressure and the detected weight of the dry clothes.

In the technical scheme of the embodiment shown in fig. 5, the current water pressure of the washing machine can be detected through a fourth corresponding relationship between the pre-calibrated water pressure of the water inlet of the washing machine and the water inlet time when the water level of the outer cylinder of the washing machine reaches the preset basic water level section from the beginning of water inlet, a third corresponding relationship corresponding to the current water pressure of the water inlet is determined according to the detected current water pressure of the water inlet, and finally, the second water inlet time is determined based on the detected weight of the dry clothes and the third corresponding relationship corresponding to the current water pressure of the water inlet, so that the condition that the accuracy of the detected second water inlet time is low due to the difference of the water pressures of the water inlet is avoided, the accuracy of the detected second water inlet time can be effectively improved, and the accuracy of weighing detection of the clothes in the inner cylinder of the washing machine can be improved to a certain extent.

Referring to fig. 1, in step S140, if the first water inlet duration is greater than or equal to the second water inlet duration, the detected dry weight is used as the actual weighing capacity of the clothes placed in the inner tub of the washing machine, and if the first water inlet duration is less than the second water inlet duration, the detected wet weight is used as the actual weighing capacity of the clothes placed in the inner tub of the washing machine.

If the first water inlet time is longer than or equal to the second water inlet time, which indicates that the clothes are placed in the inner drum of the washing machine, the detected weight of the clothes is used as the actual weight of the clothes placed in the inner drum of the washing machine. If the first water inlet time is shorter than the second water inlet time, the fact that wet clothes are placed in the inner drum of the washing machine is indicated, and the detected weight of the wet clothes is used as the actual weighing quantity of the clothes placed in the inner drum of the washing machine.

As can be seen from the above, the current dry-laundry detection weight and the current wet-laundry detection weight of the inner drum of the washing machine are determined by controlling the motor of the washing machine to rotate and based on the load power of the motor of the washing machine during rotation, the pre-stored first corresponding relationship and the second corresponding relationship; detecting a first water inlet time length from the beginning of water inlet to the time when the water level of the inner drum of the washing machine reaches a first water level section; and determining a second water inlet time length based on the detected dry clothes weight and a prestored third corresponding relation, comparing the first water inlet time length with the second water inlet time length, and determining the dry and wet states of the clothes placed in the inner drum of the washing machine, so that the detected dry clothes weight or the detected wet clothes weight is selected as the actual weighing quantity of the clothes placed in the inner drum of the washing machine according to the dry and wet states, and the accuracy of the detected clothes weight can be effectively improved. In addition, due to the fact that the accuracy of the detected weight of the clothes is improved, the optimal washing time, the optimal water inflow and the optimal detergent putting amount are determined according to the detected weight of the clothes, the washing effect of the washing machine is remarkably improved, and the user experience is improved.

Referring to fig. 6, fig. 6 shows a detailed flowchart of step S140 of a laundry weighing method of a washing machine according to an embodiment of the present application, and step S140 in this embodiment may specifically include step S610 to step S630, which are described in detail as follows.

In step S610, if the first water inlet duration is greater than or equal to the second water inlet duration, a fourth water inlet duration from the time when the water level of the inner drum of the washing machine reaches the second water level section to the time when the water level of the inner drum of the washing machine reaches the first water level section is detected, and the water level of the second water level section is higher than the water level of the first water level section.

Considering the water absorption characteristics of the laundry, since it is uncertain whether the laundry is completely immersed in water, which may cause a difference in water absorption effect of the laundry, it is necessary to determine whether the laundry placed in the drum of the washing machine is dry laundry or wet laundry according to a comparison result between water inlet times of higher water level sections, so as to improve the accuracy of detecting the dry and wet states of the laundry placed in the drum of the washing machine.

And if the first water inlet time length is greater than or equal to the second water inlet time length, detecting a fourth water inlet time length from the first water level section to the second water level section when the water level of the inner drum of the washing machine reaches the second water level section.

When the fourth water inlet time length is detected, specifically, timing can be started when the water level of the inner drum of the washing machine reaches the first water level section, the water level of the inner drum of the washing machine is continuously detected through the water level detection device, when the water level of the inner drum of the washing machine reaches the second water level section, the timing is stopped, and the time length of the timer is used as the fourth water inlet time length from the time when the water level of the inner drum of the washing machine reaches the second water level section to the time when the water level of the inner drum of the washing machine reaches the first water level section.

In step S620, a fifth water inlet duration is determined based on the detected weight of the dry clothes and a pre-stored fifth corresponding relationship, where the fifth corresponding relationship is a pre-calibrated corresponding relationship between the weight of the dry clothes placed in the inner drum of the washing machine in the water inlet state and the water inlet duration when the water level of the inner drum of the washing machine reaches the second water level section from the first water level section.

The fifth corresponding relation is the corresponding relation between the weight of the dry clothes placed in the inner barrel of the washing machine and the water inlet duration from the first water level section to the second water level section of the water level of the inner barrel of the washing machine in the pre-calibrated water inlet state.

Optionally, when the weight of the dry clothes placed in the inner drum of the washing machine and the water inlet time length when the water level of the inner drum of the washing machine reaches the second water level section from the first water level section are calibrated, dry clothes with different weights placed in the inner drum of the washing machine can be sequentially detected, and the water inlet time length when the water level of the inner drum of the washing machine reaches the second water level section from the first water level section is detected, so as to generate the fifth corresponding relation.

In step S630, if the fourth water inlet time is longer than or equal to the fifth water inlet time, the detected dry weight is used as the actual weight of the clothes placed in the inner drum of the washing machine, and if the fourth water inlet time is shorter than the fifth water inlet time, the detected wet weight is used as the actual weight of the clothes placed in the inner drum of the washing machine.

And if the fourth water inlet time is longer than or equal to the fifth water inlet time, which indicates that the clothes are placed in the inner cylinder of the washing machine, taking the detected weight of the dried clothes as the actual weight of the clothes placed in the inner cylinder of the washing machine. If the fourth water inlet time is shorter than the fifth water inlet time, which indicates that wet clothes are placed in the inner drum of the washing machine, the detected weight of the wet clothes is used as the actual weighing capacity of the clothes placed in the inner drum of the washing machine.

In the technical solution of the embodiment shown in fig. 6, by setting the second water level segment, when the first water inlet time length is greater than or equal to the second water inlet time length, the size relationship between the corresponding detected water inlet time length from the first water level segment to the second water level segment and the calibrated water inlet time length is further compared, thereby reducing the condition that the detection result of the detected water inlet time length is inaccurate due to the water absorption of the laundry, improving the accuracy of the determined detected water inlet time length, and further improving the accuracy of the detected dry-wet state of the laundry placed in the inner tub of the washing machine.

It can be understood that, in other embodiments of the present application, other water level sections with higher water level in the inner drum of the washing machine, such as the third water level section and the fourth water level section, may also be provided, and the relationship between the actual water inlet duration and the calibrated water inlet duration between the plurality of water level sections may be compared, so as to further improve the accuracy of the detected dry and wet state of the laundry placed in the inner drum of the washing machine.

In one embodiment, step S140 may further include: and determining the washing time, the water inflow and the detergent input amount when the clothes in the inner drum of the washing machine are washed based on the actual weighing amount of the clothes placed in the inner drum of the washing machine.

In order to facilitate better washing, the actual weighing amount of the clothes placed in the inner drum of the washing machine is determined, and the washing time, the water inflow and the detergent input amount of the clothes under different weights when the optimal washing effect is achieved can be established in advance according to the detected actual weighing amount of the clothes placed in the inner drum of the washing machine. The accuracy of the detected clothes weight is improved, so that the determined washing time, the determined water inflow and the determined detergent input amount are all optimal parameters, the washing effect of the washing machine can be improved, the power consumption and the water consumption of the washing machine can be reduced, and resources are saved.
