[0058] To better manage the water inlet and outlet of outer tank 3, refer to... Figures 2-3 The washing machine 100 proposed in this application embodiment includes a water circuit assembly, which includes a water inlet assembly (not shown in the figure) and a drain assembly 13. The water inlet assembly includes a water inlet pipe and a water inlet control component 7. The two ends of the water inlet pipe are respectively connected to a water supply device and an outer tub 3. The water inlet control component 7 is installed on the water inlet pipe and is used to control the connection or disconnection between the water inlet pipe and the outer tub 3, and to control whether water is introduced into the outer tub 3. The drain assembly 13 includes a drain pipe and a drain control component 8. The drain pipe is connected to the outer tub 3. The drain control component 8 is used to control the connection or disconnection between the drain pipe and the outer tub 3, and to control whether water in the outer tub 3 is drained.

[0059] It should be noted that the above-mentioned water supply device can be a faucet or a water storage tank, the above-mentioned water inlet control component 7 is a water inlet valve, or the above-mentioned water inlet control component 7 is a water inlet pump, or the water inlet control component 7 includes a water inlet valve and a water inlet pump. The water inlet control component 7 can not only control the connection or disconnection between the water inlet pipe and the outer tank 3, but also control the flow rate of water in the water inlet pipe; the above-mentioned drainage control component 8 is a drainage valve, or the above-mentioned drainage control component 8 is a drainage pump, or the drainage control component 8 includes a drainage valve and a drainage pump. The drainage control component 8 can not only control the connection or disconnection between the drainage pipe and the outer tank 3, but also control the flow rate of water in the drainage pipe.

[0060] In order to better control the operation of the washing machine 100, in some embodiments of the present application, a concentration detection component 11 is arranged inside the outer tub 3, which is used to detect the detergent concentration of the washing water in the outer tub 3. During the washing process, the detergent concentration of the washing water is detected to determine the total amount of detergent in the washing water, so as to determine whether the detergent or washing powder needs to be supplemented into the washing water to ensure the cleaning degree of the clothes.

[0061] In some embodiments of the present application, in order to improve the accuracy of the detergent concentration detection, the concentration detection component 11 is arranged at the bottom of the outer tub 3 to detect the detergent concentration of the washing water at the bottom of the outer tub 3. For example, the concentration detection component 11 can be arranged at the position close to the drain pipe at the bottom of the outer tub 3, so as to detect the detergent concentration at the position with the lowest detergent concentration inside the outer tub 3, so as to ensure the detergent concentration inside the entire outer tub 3 and the overall cleaning degree.

[0062] For example, the concentration detection component 11 can be a concentration detection sensor (an online refractometer) or a specific gravity detection sensor, etc. The concentration detection sensor is composed of a light source, a sapphire refractometer, a light receiver and a signal modulation circuit, which uses optical principle to determine the concentration value of the detergent in the washing water through the light transmittance and refractive index of the washing water. Specifically, the light source emits a stable light signal which is transmitted through the sapphire and contacts the measured medium, and the refractive index corresponding to the concentration of the measured medium is generated, and the light receiver calculates the refractive index to obtain the corresponding concentration through data algorithm.

[0063] In some embodiments of the present application, a water level detection component 10 is arranged at the bottom of the outer tub 3, which is used to detect the water level of the washing water in the outer tub 3. For example, the water level detection component 10 is arranged as a water level sensor which can convert the water level parameter of the measured point into a corresponding electric quantity signal in real time. The water level sensor in the outer tub 3 transmits the sensed water level signal to the controller 9 of the washing machine 100, and the processor in the controller 9 compares the measured water signal with the set signal to obtain the deviation, and then according to the nature of the deviation, sends the opening / closing instruction to the water inlet control component 7 and the drain control component 8, so as to ensure that the water level in the outer tub 3 meets the washing requirement.

[0064] In order to monitor the cleaning degree of the washing water, a turbidity detection component 12 is further arranged inside the outer tub 3, which is used to detect the turbidity of the washing water. For example, the turbidity detection component 12 is arranged as a turbidity sensor which is used to detect the turbidity of the washing water, and determine whether the current washing water needs to be discharged.

[0065] In order to improve the working efficiency of the washing machine 100, the working process of the washing machine 100 is controlled, and in some embodiments of the present application, the controller 9 in the present application includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), a RAM (Random Access Memory), a ROM (Read-Only Memory), a first interface to an n-th interface for input / output, a communication bus, and the like.

[0066] The controller 9 controls the operation of the washing machine 100 and responds to the operation of the user by various software control programs stored on the memory, and the controller 9 controls the overall operation of the washing machine 100. For example, in response to the received operation instruction for output, the controller 9 can perform an operation related to the component selected by the operation instruction.

[0067] Referring to Figure 5 , the controller 9 is electrically connected with the washing control component 6, the water inlet control component 7, the drainage control component 8, the water level detection component 10, the concentration detection component 11, and the concentration detection component 11. The controller 9 receives the values detected by the water level detection component 10, the concentration detection component 11, and the concentration detection component 11, and controls the working state of the washing control component 6, the water inlet control component 7, and the drainage control component 8 according to the control logic set by itself, to maintain the normal operation of the washing machine 100 after restarting.

[0068] After the washing program of the washing machine 100 is interrupted, because the washing process is not completed, the user needs to restart the washing machine 100 to complete the washing work, so as to achieve the purpose of cleaning the clothes. In the related art, the washing water in the washing machine 100 is emptied after restarting, which causes waste of water resources, or when the washing machine 100 is started for the second time, the washing agent is put in again, which causes waste of washing agent, prolongs the overall washing time, and reduces the user's experience.

[0069] In order to realize the efficient operation of the washing machine 100 after the washing program is interrupted and restarted, the water level and the concentration of the washing agent are detected in the present application to control whether water needs to be supplied and whether the washing agent or washing powder needs to be put in, which can effectively reduce the number of rinsing, shorten the washing time, and reduce the waste of water resources and washing agent.

[0070] Specifically, the controller 9 is configured to, when the washing program of the washing machine 100 is interrupted, the washing machine 100 is restarted, based on the water level value of the washing water detected by the water level detection component 10 after the restart, the water inlet valve or the water outlet valve is operated; based on the washing water concentration value detected by the concentration detection component 11 after the water outlet or the water inlet, the electromagnetic valve is operated.

[0071] Through the above steps, when the washing machine 100 is restarted, it is first determined whether water inlet or water outlet is needed according to the water level value of the washing water, so as to avoid water resource waste caused by direct water outlet and repeated water inlet for water supplement in the washing program; after the washing water in the outer tub 3 reaches the washing requirement, it is then determined whether the washing agent is re-input or continuously input according to whether the washing agent concentration of the washing water reaches the washing requirement, so as to avoid the situation that repeated input of the washing agent leads to excessive washing agent content and increased rinsing times. After the improvement, the energy waste caused by the washing machine 100 being turned off due to misoperation or other reasons can be effectively solved, the working time of the washing machine 100 is shortened, the washing efficiency is improved, and the user's satisfaction is improved.

[0072] In some embodiments of the present embodiment, with reference to Figure 6 , the controller 9 is configured to, after the washing machine 100 is restarted, first detect whether the current working program is a washing program (step S1).

[0073] In step S1, it is determined that the current working program is a washing program, step S2 is executed, and it is determined whether the water level of the washing water in the outer tub 3 after the restart reaches a preset washing water level value;

[0074] In step S2, it is determined that the water level of the washing water in the outer tub 3 after the restart reaches the preset washing water level value, step S3 is executed, it is determined that the washing water at this time is excessive, the water outlet valve is opened, and then step S4 is executed, it is determined whether the water level of the washing water in the outer tub 3 at this time reaches a preset washing water level.

[0075] In step S4, it is determined that the water level of the washing water in the outer tub 3 reaches the preset washing water level, step S5 is executed, and the water outlet valve is closed.

[0076] In step S4, it is determined that the water level of the washing water in the outer tub 3 does not reach the preset washing water level, and step S3 is continuously executed.

[0077] Through the above steps, the control method of the washing machine 100 for water inlet and water outlet when the water level of the washing water in the outer tub 3 after the restart is above the preset washing water level is solved, the waste of water resources is effectively reduced, and the washing requirement of the washing machine 100 can be met at the same time.

[0078] In some embodiments of the present embodiment, with reference to Figure 7, when the water level of the washing water in the outer tub 3 reaches the preset water level after the draining, the controller 9 is configured to execute step S6 to determine whether the detergent concentration of the washing water after the draining detected by the concentration detecting member 11 is below the preset concentration threshold value;

[0079] When it is determined in step S6 that the detergent concentration of the washing water after the draining detected by the concentration detecting member 11 is below the preset concentration threshold value, step S71 is executed to open the washing control device, and the detergent in the washing box 5 enters the outer tub 3, and then step S8 is executed to determine whether the detergent concentration reaches the preset concentration threshold value;

[0080] When it is determined in step S8 that the detergent concentration reaches the preset concentration threshold value, step S81 is executed to close the washing control device, and the detergent in the washing box 5 stops entering the outer tub 3, and then step S9 is executed to continue the washing program; when it is determined in step S8 that the detergent concentration does not reach the preset concentration threshold value, step S71 is executed.

[0081] When it is determined in step S6 that the detergent concentration of the washing water after the draining detected by the concentration detecting member 11 does not reach the preset concentration threshold value, step S72 is executed to keep the washing control device closed, and the washing box 5 does not supply the detergent to the outer tub 3; and then step S9 is executed to continue the washing program.

[0082] Through the above steps, the problem of detergent supply when the water level in the outer tub 3 is above the preset water level after the restart is solved, and the problem of excessive detergent supply, increased rinsing times, or insufficient detergent and poor washing effect is prevented.

[0083] In some embodiments of the present embodiment, the controller 9 is configured to, when the water level value detected by the water level detecting member 10 does not reach the preset water level value, determine that the water level value reaches the preset empty tub water level value, and the water inlet valve is opened until the water level value reaches the preset water level value.

[0084] The opening of the electromagnetic valve is determined according to the concentration value of the detergent in the washing water after the water inlet detected by the concentration detecting member 11.

[0085] In some embodiments of the present embodiment, with reference to Figure 8 , the controller 9 is further configured to, when it is determined in step S2 that the water level value detected by the water level detecting member 10 does not reach the preset water level value, execute step S301 to determine whether the water level value detected by the water level detecting member 10 reaches the preset empty tub water level value.

[0086] When it is determined in step S301 that the water level value reaches the preset empty tub water level value, step S302 is executed to open the water inlet control member 7, and then step S303 is executed to determine whether the water level value detected by the water level detecting member 10 reaches the preset water level value.

[0087] In step S303, when the water level value reaches the preset washing water level value, step S3031 is executed to close the water inlet component 7, and then step S304 is executed to determine whether the detergent concentration value of the water inlet detergent detected by the concentration detection component 11 is below the preset concentration threshold value;

[0088] In step S304, when the detergent concentration value of the water inlet detergent detected by the concentration detection component 11 is below the preset concentration threshold value, step S305 is executed to open the washing control component 6, and the detergent in the washing box 5 enters the outer tub 3, and then step S306 is executed to determine whether the detergent concentration of the washing water at this time reaches the preset concentration threshold value;

[0089] In step S306, when the detergent concentration of the washing water at this time reaches the preset concentration threshold value, step S307 is executed to close the washing control component 6, and the washing box 5 does not supply detergent to the outer tub 3, and then step S308 is executed to continue the washing program;

[0090] In step S306, when the detergent concentration of the washing water at this time does not reach the preset concentration threshold value, step S305 is continuously executed;

[0091] In step S304, when the detergent concentration value of the water inlet detergent detected by the concentration detection component 11 does not reach the preset concentration threshold value, step S308 is executed to continue the washing program;

[0092] In step S303, when the water level value does not reach the preset washing water level value, step S302 is continuously executed.

[0093] Through the above steps, the problems of water inlet, water outlet and detergent supply of the washing machine 100 when the washing water in the outer tub 3 is between the preset empty tub water level value and the preset washing water level value after restart are solved, the water resource waste caused by direct drainage is saved, and the problems of increased rinsing times and washing time caused by excessive detergent supply, and the problems of insufficient detergent and poor washing effect are effectively prevented.

[0094] In some embodiments of the present embodiment, the turbidity sensor of the washing machine 100 is arranged at the bottom of the outer tub 3, and the turbidity sensor is used to detect the turbidity of the washing water inside the outer tub 3.

[0095] Based on this, the controller 9 is configured to, when the water level value detected by the water level detection component 10 does not reach the preset empty tub water level value, execute the opening or closing of the water inlet valve and the opening or closing of the water inlet valve based on the turbidity value detected by the turbidity detection sensor, and execute the opening or closing of the electromagnetic valve based on the detergent concentration value of the water inlet washing water.

[0096] In some embodiments of the present embodiment, in some embodiments, the controller 9 is configured to open the drain valve when the turbidity value detected by the turbidity detection sensor reaches above the preset turbidity threshold, close the drain valve after the washing water in the outer tub 3 is drained, open the water inlet valve, close the water inlet valve when the water level in the outer tub 3 reaches the preset washing water level, open the electromagnetic valve, and add the detergent into the outer tub 3 until the washing water concentration reaches the preset washing threshold.

[0097] In some embodiments of the present embodiment, the controller 9 is configured to open the water inlet valve when the turbidity value detected by the turbidity detection sensor does not reach above the preset turbidity threshold, close the electromagnetic valve when the detergent concentration value detected by the concentration detection component 11 reaches the preset concentration threshold after the water level in the outer tub 3 reaches the preset washing water level, and open the electromagnetic valve when the detergent concentration value detected by the concentration detection component 11 does not reach the preset concentration threshold.

[0098] Referring to Figure 9 Further, the working process of the washing machine 100 is described as follows. Specifically, in step S301, it is determined that the water level value detected by the water level detection component 10 does not reach above the preset empty cylinder water level value, step S401 is executed, and it is determined whether the turbidity value detected by the turbidity detection sensor reaches above the preset turbidity threshold.

[0099] In step S401, it is determined that the turbidity value detected by the turbidity detection sensor reaches above the preset turbidity threshold, step S402 is executed, the drain control component 8 is opened, step S403 is executed, and it is determined whether the washing water in the outer tub 3 is completely drained.

[0100] In step S403, it is determined that the washing water in the outer tub 3 is completely drained, step S404 is executed, the drain control component 8 is closed, then step S405 is executed, the water inlet control component 7 is opened, step S406 is executed, and it is determined whether the water level value detected by the water level detection component 10 reaches the preset washing water level.

[0101] In step S406, it is determined that the water level value detected by the water level detection component 10 reaches the preset washing water level, step S407 is executed, the water inlet control component 7 is closed, then step S408 is executed, the washing control component 6 is opened, the detergent is added into the outer tub 3, and step S409 is executed, and it is determined whether the detergent concentration of the washing water detected by the concentration detection component 11 reaches the preset concentration threshold.

[0102] In step S409, it is determined that the detergent concentration of the washing water detected by the concentration detection component 11 reaches the preset concentration threshold, step S410 is executed, and the washing control component 6 is closed.

[0103] In step S409, it is determined that the detergent concentration of the washing water detected by the concentration detection component 11 does not reach the preset concentration threshold, and step S408 is continuously executed.

[0104] If the water level value detected by the water level detection component 10 does not reach the preset washing water level in step S406, step S405 is continued to be executed;

[0105] If the washing water in the outer tub 3 is not completely drained in step S403, step S402 is continued to be executed;

[0106] If the turbidity value detected by the turbidity detection sensor does not reach the preset turbidity threshold in step S401, step 405 is executed.

[0107] Through the above steps, the problems of water filling, water draining and detergent dispensing of the washing machine 100 when the washing water in the outer tub 3 is less than the preset emptying water level value after restarting are solved, which avoids the turbidity of the washing water in the outer tub 3 caused by direct water filling, affects the washing effect, and effectively prevents the problems of increasing the number of rinsing and increasing the washing time caused by excessive detergent dispensing, and the problem of insufficient detergent and poor washing effect.

[0108] The washing machine 100 in the present application includes various working programs, including a washing program, and non-washing programs such as a rinsing program, a drying program and a dehydration program. In the present application, after the work is interrupted and restarted, the working program before interruption or at this time is first judged, and then the working state of each component of the washing machine 100 is controlled according to the type of the obtained working program.

[0109] In some embodiments of the present embodiment, it is first judged whether it is a washing program, when the non-washing program of the washing machine 100 is interrupted and the washing machine 100 is restarted again, the controller 9 is configured to open the drain valve when the turbidity value detected by the turbidity detection component 12 reaches the preset turbidity threshold.

[0110] In some embodiments of the present embodiment, when the non-washing program of the washing machine 100 is interrupted and the washing machine 100 is restarted again, the controller 9 first judges whether the execution program of the washing machine 100 is a washing program.

[0111] Reference Figure 10 When it is judged in step S1 that the washing machine 100 is in a non-washing program, step 501 is executed to judge whether the turbidity value detected by the turbidity detection component 12 reaches the preset turbidity threshold;

[0112] If the turbidity value detected by the turbidity detection component 12 reaches the preset turbidity threshold in step S501, step S502 is executed to open the drain control component 8.

[0113] If the turbidity value detected by the turbidity detection component 12 does not reach the preset turbidity threshold in step S501, step S503 is executed to open the water filling control component 7.

[0114] By the above steps, the problem of restarting the washing machine 100 after the program interruption in the non-washing program is solved, the influence of the turbidity of the washing water in the outer tub 3 on the rinsing or spinning is fully considered, and the efficiency of the rinsing or spinning is improved.

[0115] Referring to Figure 11 , the working process of the washing machine 100 after the restart is described.

[0116] Firstly, it is judged whether the working program of the washing machine 100 at this time is the washing program (step S601). In step S601, it is judged that the current working program is the washing program, and then step S602 is executed to judge whether the water level L0 in the outer tub 3 reaches above the preset washing water level;

[0117] In step S602, when it is judged that the water level L0 in the outer tub 3 reaches above the preset washing water level value L1, step S603 is executed to start draining, and step S604 is executed to judge whether the water level in the outer tub 3 reaches the preset washing water level value L1;

[0118] In step S604, when it is judged that the water level L0 in the outer tub 3 reaches the preset washing water level value L1, step S605 is executed to stop draining, and then step S606 is executed to detect the detergent concentration C0 and judge whether the detergent concentration C0 is not less than the preset concentration threshold C1;

[0119] In step S606, when the detergent concentration C0 is not less than the preset concentration threshold C1, step S607 is executed to not add detergent,

[0120] In step S606, when the detergent concentration C0 is less than the preset concentration threshold C1, step S608 is executed to continue adding detergent until the detergent concentration reaches the preset concentration threshold C1;

[0121] In step S602, when it is judged that the water level L0 in the outer tub 3 does not reach above the preset washing water level value L1, step S609 is executed to judge whether the water level L0 in the outer tub 3 reaches above the preset empty cylinder water level value L2;

[0122] In step S609, when it is judged that the water level L0 in the outer tub 3 reaches above the preset empty cylinder water level value L2, step S610 is executed to supplement water to the outer tub 3 until the water level reaches the preset washing water level L1; and then step S606 is executed.

[0123] In step S609, when it is judged that the water level L0 in the outer tub 3 does not reach above the preset empty cylinder water level value L2, step S611 is executed to judge whether the turbidity value N0 of the washing water in the outer tub 3 is not less than the preset turbidity threshold N1;

[0124] If the turbidity value N0 of the washing water in the outer tub 3 is not less than the preset turbidity threshold N1 in step S611, step S612 is performed to drain the outer tub 3 to empty, and then step S613 is performed to fill water to make the water level in the outer tub 3 reach the preset washing water level value L1, and then step S614 is performed to add the detergent into the outer tub 3 to make the detergent concentration reach the preset concentration threshold C1.

[0125] If the turbidity value N0 of the washing water in the outer tub 3 is less than the preset turbidity threshold N1 in step S611, step S613 is performed.

[0126] If the current working program is not the washing program in step S601, step S603 is performed to directly drain to empty, and then the corresponding subsequent program is entered.

[0127] In the above embodiment, the washing machine 100 includes the outer tub 3 for storing washing water, the washing box 5 for containing detergent, the electromagnetic valve for controlling whether the detergent in the washing box 5 enters the outer tub 3, the water inlet pipeline for water inlet, the water inlet valve arranged on the water inlet pipeline, the water outlet pipeline for water outlet, the water outlet valve arranged on the water outlet pipeline, the concentration detection component 11 for detecting the detergent concentration of the washing water in the outer tub 3, and the water level detection component 10 for detecting the water level of the washing water in the outer tub 3. The controller 9 coordinates the working of the washing machine 100 according to the above components. Specifically, after the washing program of the washing machine 100 is interrupted and the washing machine 100 is restarted, the water inlet valve and the water outlet valve are operated based on the water level value of the washing water detected by the water level detection component 10 after the restart; and the electromagnetic valve is operated based on the detergent concentration value of the washing water detected by the concentration detection component 11 after the water outlet or water inlet. By detecting the water level of the washing water first after the restart to determine whether to drain or fill water, the waste of water resources caused by direct draining after the restart is avoided. The water inlet or water outlet can effectively reduce the time wasted by the washing machine 100 from the beginning. The opening and closing of the electromagnetic valve are controlled according to the detergent concentration value of the washing water after the water outlet or water inlet, so as to adjust the detergent concentration value of the washing water to meet the required concentration for washing, improve the cleaning efficiency and effect, and improve the user satisfaction.

[0128] The washing machine 100 provided in the application effectively solves the problem that when the washing starts, the detergent is added and water is filled due to the child's misoperation to close the washing machine 100 or other reasons to close the washing machine 100, and the automatic detergent adding of the washing machine 100 will add detergent again when the washing machine 100 is started for the second time, causing waste of detergent. If the detergent is excessive, the number of rinsing times increases, and water and electricity are wasted. After the improvement, the detergent can be added according to the program selection and the actual bottom detergent concentration, so as to avoid waste.
