Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the related technology, the drum washing machine comprises a shell and a drum, the drum comprises an inner drum and an outer drum, the outer drum is fixed in the shell, the inner drum is rotatably arranged in the outer drum, a water passing gap is formed between the inner drum and the outer drum at intervals, the inner drum is provided with water passing holes communicated with the water passing gap, clean water is injected into the water passing gap through a water supply device in the washing process of the washing machine, and the clean water flows into the inner drum through the water passing holes. However, because the drum adopts the above structure, some inevitable impurities such as lint, leather scraps, thread scraps and the like remain on the outer side wall of the inner drum or the inner side wall of the outer drum during drainage, so that mildew is bred in a humid environment for a long time, washing water is polluted, secondary pollution is caused to clothes during washing, the clothes cannot be cleaned, and the use experience of a user is influenced.

In order to solve the above problem, embodiments of the present application provide a control method of a washing machine.

Referring to the drawings, fig. 1 is a first flowchart of a control method of a washing machine according to an embodiment of the present disclosure. In an embodiment of the present application, a control method of a washing machine includes:

101: after the last rinsing operation of the washing machine is finished, the dirt value of the washing water in the drum is detected.

Specifically, the water quality detector may detect a turbidity value of water. For example, the water quality detector may be a stain sensor, and the stain sensor may be provided in the drum, and the stain condition in the drum may be determined by a stain value of the washing water detected by the stain sensor.

For example, the washing machine includes a drum including an outer drum and an inner drum rotatably disposed in the outer drum, a water passing gap is formed between the outer drum and the inner drum at an interval, and the inner drum is provided with water passing holes communicated with the water passing gap. The dirt sensor can be arranged at the bottom of the inner side wall of the outer barrel, and the dirt value of the washing water in the roller can be detected through the dirt sensor.

The washing machine further comprises a controller, wherein the stain sensor feeds back the detected stain value to the controller, so that the controller determines whether the drum needs to be cleaned according to the stain value, and then outputs a corresponding execution instruction.

It can be understood that the last rinsing of the washing machine is to fill clean water into the drum to clean the laundry, and the embodiment of the present application detects the turbidity value of the washing water after the last rinsing operation of the washing machine is finished, so that the detergent remained in the washing water is less, the stains washed from the clothes are few, the interference of residual detergent or stains in the washing water to detection can be avoided, the dirt on the roller can fall into the washing water after rinsing, and the relative accuracy of the detection result can be ensured.

102: and if the dirt value is lower than the preset dirt value, controlling the washing machine to stop after the washing of the washing machine is finished.

It should be noted that the preset contamination degree value is a reference value preset in a control program of the controller, and the preset contamination degree value may be a fixed value or a value interval.

It can be understood that if the dirty degree value is lower than the preset dirty degree value, that is, the washing water in the drum is relatively clean, and the drum does not need to be cleaned, then the controller controls the washing machine to execute the remaining instruction of the washing program, that is, the dehydration process of the clothes is executed, and after the dehydration is finished, the washing machine is controlled to stop.

103: and if the dirt value is higher than the preset dirt value, injecting water into the rotary drum after the washing machine finishes washing.

It can be understood that if the dirty degree value is higher than predetermineeing dirty degree value, the washing water in the cylinder is dirty relatively promptly, then means that the cylinder is inside dirty, and in washing machine cleaning process, the dirt on urceolus inside wall and the inner tube lateral wall falls into the washing water for dirty degree value that dirt sensor detected is high, then needs clean the cylinder to prevent that next washing from causing secondary pollution to the clothing.

And after the washing machine finishes washing, corresponding washing operation is carried out on the roller, namely the control method of the embodiment of the application cleans the roller after a complete washing program of the clothes is finished, so that the use habit of a user is met, and the user is prevented from waiting for a long time to take out the clothes.

To prevent the laundry from being contaminated during the drum cleaning process, the laundry in the drum needs to be taken out before the drum is cleaned. Specifically, referring to fig. 2, the step of injecting water into the drum includes the following steps:

1031: and if the clothes in the drum are not taken out, controlling the washing machine to give an alarm.

An image recognition module may be disposed in the washing machine, for example, the image recognition module may be a camera, and the image recognition module acquires an image of the inside of the inner drum and recognizes the acquired image to determine whether the laundry in the drum is taken out.

If the situation that the clothes in the drum are not taken out is detected, the drum cannot be cleaned, and the controller controls the washing machine to give an alarm, such as an alarm sound, and display the alarm on a display screen of the washing machine so as to prompt a user to take out the clothes in time.

1032: if the clothes in the drum are taken out, whether the door of the washing machine is closed or not is detected.

It can be understood that, since water needs to be filled into the drum, in order to prevent water in the drum from leaking out, the door of the washing machine needs to be closed when the drum is cleaned. Moreover, the drum is cleaned to generate noise inevitably, and the door cover of the washing machine is used for executing the washing operation, so that the noise generated in the drum washing process can be reduced to a certain extent, and the use experience of a user is prevented from being influenced.

The door lock of the door cover of the drum washing machine is generally an electromagnetic lock, and whether the door cover of the washing machine is closed or not can be determined by detecting a door lock circuit.

If the door cover of the washing machine is not closed, the controller controls the washing machine to give an alarm again to prompt a user to close the door in time.

1033: and if the door cover of the washing machine is detected to be closed, filling water into the roller.

For example, if it is detected that the door of the washing machine is closed, the controller controls the water supply device to fill water into the drum to a preset water level.

The preset water level is a reference water level preset in a control program of the controller. The preset water level can be one half of the water level line in the roller submerging the outer peripheral wall of the inner cylinder (namely the central angle of the inner cylinder corresponding to the water level line in the roller is 180 degrees), or one third of the water level line in the roller submerging the outer peripheral wall of the inner cylinder (namely the central angle of the inner cylinder corresponding to the water level line in the roller is 120 degrees), the preset water level can be determined according to parameters such as the power of the ultrasonic device, the size of the roller and the like, and the specific set value of the preset water level is not limited herein.

It can be understood that when the actual water level in the drum reaches the preset water level, the controller controls the washing machine to stop water injection. Among them, the washing machine can detect the actual water level in the drum by detecting the water level frequency, and the water level detection principle of the washing machine is a prior art and will not be described in detail herein.

104: and circularly carrying out ultrasonic cleaning on the roller until the turbidity value of the washing water in the roller is lower than the preset turbidity value, and stopping cleaning.

Specifically, ultrasonic waves act on washing water in the roller, the ultrasonic waves can generate cavitation, energy emitted by the ultrasonic waves can generate a large number of bubbles to the washing water and break the bubbles continuously, and impact waves with the pressure as high as hundreds of atmospheres can be generated when the bubbles break, so that dirt on the outer side wall of the inner cylinder and the inner side wall of the outer cylinder is broken and peeled off, and the roller is cleaned.

For example, the washing machine may be provided with an ultrasonic device, and the ultrasonic device may be installed and fixed at the bottom of the inner sidewall of the outer tub, so that the ultrasonic device can emit ultrasonic waves to the washing water in the drum.

Of course, in some embodiments, ultrasonic energy may also be applied to the washing water in the drum by introducing ultrasonic waves from outside the washing machine.

Therefore, in the control method of the washing machine provided by the embodiment of the application, by detecting the contamination degree of the washing water after the last rinsing is finished, if the contamination degree value of the washing water is higher than the preset contamination degree value, that is, the water quality of the washing water is dirty, it means that the drum is dirty, and the degree that the drum needs to be cleaned is reached.

In addition, according to the control method of the embodiment of the application, the washing water in the drum is detected after the last rinsing of the washing machine is finished, and as the washing machine is used for washing the clothes by injecting clean water into the drum in the last rinsing, the residual detergent in the washing water is less, the stains washed from the clothes are less, the interference of the residual detergent or the stains in the washing water on the detection can be avoided, and the stains on the drum can fall into the washing water after the rinsing, so that the relative accuracy of the detection result is ensured.

In the embodiment of the present application, the ultrasonic cleaning specifically includes the following steps:

a: starting the ultrasonic device to act on the washing water in the drum.

Specifically, the ultrasonic waves act on the washing water in the drum, the ultrasonic waves can generate cavitation, the energy generated by the ultrasonic waves can generate a large amount of bubbles to the washing water and break the bubbles continuously, and impact waves up to hundreds of atmospheric pressures can be generated when the bubbles break, so that the dirt on the outer side wall of the inner drum and the dirt on the inner side wall of the outer drum can be broken and peeled off.

b: and controlling the inner cylinder to rotate by a first angle every second time until the peripheral wall of the inner cylinder is completely cleaned by ultrasonic.

It should be noted that the first angle refers to a central angle of the inner cylinder corresponding to the water level line when the water is filled to the preset water level.

For example, taking a preset water level as an example that the water level line in the drum submerges one third of the outer peripheral wall of the inner drum, the central angle corresponding to the water level line in the drum is 120 °, and after the ultrasonic device works for a second time period, the controller controls the inner drum to rotate 120 °, so that the other third of the outer peripheral wall of the inner drum is immersed into the water, and the ultrasonic device performs an ultrasonic cleaning operation on the other third of the outer peripheral wall of the inner drum.

After the ultrasonic device works for a second time, the controller controls the inner cylinder to rotate 120 degrees again, so that the remaining third of the outer peripheral wall of the inner cylinder is immersed into the water, the ultrasonic device performs ultrasonic cleaning operation on the remaining third of the outer peripheral wall of the inner cylinder, and the whole outer peripheral wall of the inner cylinder is cleaned by ultrasonic.

Referring to fig. 3, fig. 3 is a flowchart illustrating a specific step of step 104 of the control method in fig. 1. In the embodiment of the application, the roller circulation ultrasonic cleaning comprises the following steps:

1041: after one ultrasonic cleaning operation is finished, the turbidity value of the washing water in the drum is detected.

Through carrying out the dirty turbidity of ultrasonic cleaning back direct detection washing water once, instead of water injection detection again behind the drainage, can avoid remaining stubborn dirt on the inner tube and not falling into the aquatic and lead to the spot sensor to fail to detect, avoid the spot sensor to cause the erroneous judgement to the dirty condition of cylinder. Moreover, water can be saved, and the water consumption cost of a user is reduced.

1042: and if the difference value between the currently detected dirt degree value and the previously detected dirt degree value is less than or equal to a first preset value, controlling the washing machine to stop.

For example, taking a washing machine performing two times of ultrasonic cleaning as an example, since the drum is subjected to two times of ultrasonic cleaning, most of dirt on the drum can be peeled off during the first cleaning, and the washing water in the drum after the second cleaning is much cleaner than the washing water in the drum after the first cleaning, under normal conditions, the dirt value detected for the third time is much smaller than the dirt value detected for the second time, and if the difference between the dirt value detected for the third time and the dirt value detected for the second time is small, there may be a case that the dirt sensor fails or the ultrasonic device fails, resulting in a small difference between the detection results of the two times.

In contrast, in the embodiment of the present application, the currently detected turbidity value is compared with the previous detected turbidity value, and if the difference between the currently detected turbidity value and the previous detected turbidity value is less than or equal to the first preset value, that is, the results of the previous and subsequent detections of the turbidity values are not normal, the sensor may fail or the ultrasonic device may fail, so as to avoid ineffective cleaning of the drum due to the fact that the drum is clean, and the controller controls the washing machine to stop.

Of course, the controller can also control the washing machine to give an alarm to prompt a user to overhaul the washing machine so as to check whether the stain sensor or the ultrasonic device is abnormal.

1043: and if the difference value between the currently detected dirt degree value and the dirt degree value detected at the front side is larger than a first preset value, acquiring the times of ultrasonic cleaning operation.

Specifically, the currently detected dirt value is compared with the dirt value detected last time, and if the difference value between the currently detected dirt value and the dirt value detected last time is larger than a first preset value, namely the dirt detection results of the previous two times are normal, the next ultrasonic cleaning can be performed on the roller.

However, in order to avoid the excessive number of times of ultrasonic cleaning, the present embodiment presets the maximum number of times of ultrasonic cleaning in the control program of the controller, and if the difference between the currently detected contamination degree value and the previously detected contamination degree value is greater than the first preset value, the present embodiment further determines whether ultrasonic cleaning needs to be performed again by acquiring the number of times of ultrasonic cleaning.

1044: and if the ultrasonic cleaning times reach the preset times, controlling the washing machine to stop.

It can be understood that, in order to save the electricity cost and the water cost, the number of times of ultrasonic cleaning is not excessive, and when the number of times of ultrasonic cleaning reaches the preset number, the controller controls the washing machine to stop.

1045: and if the dirt value is lower than the preset dirt value, emptying the washing water in the drum and controlling the washing machine to stop.

Because this embodiment directly detects the washing water after carrying out an ultrasonic cleaning, there is the dirt that peels off from inner tube and urceolus in the washing water, if the dirty degree value that detects is less than predetermineeing dirty degree value, and the washing water is comparatively clean promptly, means that the cylinder has been cleaned totally.

At the moment, the controller controls the drainage port of the washing machine to be opened, so that the washing water in the drum is drained, and the controller controls the washing machine to stop when the water is drained completely.

1046: and if the dirt value is higher than the preset dirt value, emptying the washing water in the roller.

1047: and injecting water into the roller, and continuously carrying out ultrasonic cleaning on the roller.

If the number of times of ultrasonic cleaning does not reach the preset number of times, continuing to perform next ultrasonic cleaning, controlling the water supply device to inject water into the roller to the preset water level by the controller, and then starting the ultrasonic device to work.

Please refer to fig. 4, and fig. 4 is a second flowchart of the control method of the washing machine according to the embodiment of the present application. In this embodiment, the control method of the washing machine includes steps 201 to 206, wherein

steps

201, 202, 203 and 205 are the same as steps 101 to 104 of the control method of the washing machine provided in the above embodiment, and detailed description thereof is omitted.

201: and detecting the dirt value of the washing water in the drum if the last rinsing of the washing machine is finished. See the above embodiments for details.

202: and if the dirt value is lower than the preset dirt value, controlling the washing machine to stop after the washing of the washing machine is finished. See the above embodiments for details.

203: and if the dirt value is higher than the preset dirt value, injecting water into the drum after the washing machine finishes washing. See the above embodiments for details.

204: the washing water in the drum is heated.

It can be understood that the washing water in the drum is heated by the heating device, so that the temperature of the washing water is raised, the dirt on the inner drum and the outer drum can be softened, the dirt can be easily peeled off under the action of external force, and the high temperature has a certain sterilization effect, so that the washing water can kill part of bacteria with poor heat resistance.

For example, a heating device may be disposed in the washing machine, for example, the heating device may be an electric heating pipe, the electric heating pipe may be installed and fixed at the bottom of the inner side wall of the outer drum, when water is injected into the drum, the injected clean water may flood the electric heating pipe, and when the electric heating pipe is powered on, the washing water in the drum is heated.

The washing machine may further be provided with a temperature sensor disposed at the bottom of the inner sidewall of the outer tub, the temperature sensor being used to detect a real-time temperature of the washing water in the drum and feed the temperature of the washing water back to the controller, and the controller controls the heating device to stop working when the temperature of the washing water in the drum rises to a preset temperature.

Because heating device heating washing water needs a period of time to predetermineeing the temperature for dirt on urceolus and the inner tube has certain time and soaks in hot water and softens, and the ultrasonic cleaning of cooperation next step will be attached to the dirt of urceolus inside wall and inner tube lateral wall and peel off very easily, promotes the clean efficiency to the cylinder.

205: and circularly carrying out ultrasonic cleaning on the roller until the dirt value of the washing water in the roller is lower than the preset dirt value. See the above embodiments for details.

206: and injecting water into the roller, and simultaneously controlling the roller to rotate for a first time.

In the cleaning process of the roller, dirt on the outer side wall of the inner barrel and the inner side wall of the outer barrel are peeled into washing water under the action of ultrasonic waves, and a small part of dirt still adheres to the outer side wall of the inner barrel or the inner side wall of the outer barrel during water drainage, so that the dirt is directly suspended in the washing water when meeting water and adheres to clothes after dehydration during next washing of the clothes, and the clothes are polluted.

Then, in the present embodiment, after the ultrasonic cleaning operation is completed and the washing water in the drum is drained (it has been described above that the ultrasonic cleaning operation is circulated until the washing water in the drum is drained when the contamination value of the washing water in the drum is lower than the pre-examination contamination value), the dirt attached to the outer wall of the inner tub and the inner wall of the outer tub can be detached by the washing of the water flow by injecting the water into the drum.

It should be noted that, in the process of filling water into the drum, the controller controls the water outlet of the washing machine to be still in an open state, that is, while filling water into the drum, the filled clean water is directly discharged from the water outlet, so that the dirt separated from the outer drum and the inner drum under the washing of water flow is directly discharged.

Moreover, in order to further improve the washing effect, the present embodiment also controls the rotation of the drum (inner cylinder) while injecting water. For example, the drum (inner cylinder) can be controlled to rotate forward and backward for a first time period so that the inner cylinder is matched with the washing of water flow in a rotating manner, the washing force of the water flow on dirt attached to the inner cylinder and the outer cylinder is enhanced, the washing effect is further improved, and the dirt attached to the inner cylinder and the outer cylinder is ensured to be easily separated and discharged along with the water flow.

The present application also provides a storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the control method of the washing machine as described in the above embodiments.

The application also provides a washing machine, and particularly relates to the washing machine adopting the control method.
