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 will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic flow chart of a control method of a washing machine according to an embodiment of the disclosure. The embodiment of the application provides a control method of a washing machine, wherein the washing machine can be a drum-type washing machine or a pulsator-type washing machine, the washing principle of the pulsator-type washing machine is different from that of the drum-type washing machine, a disc pulsator is arranged at the bottom of a drum of the pulsator-type washing machine, and protruding ribs are arranged on the disc pulsator. The water flow in the cylinder forms vortex which is clockwise and rightwards rotated and is clockwise and leftwards rotated under the drive of the impeller, the fabric is driven to rotate and roll, so that dirty articles on the clothes can be removed. The drum-type washing machine is designed by simulating the principle of beating clothes by hammering a rod, and generates huge centrifugal force to do repeated motion when the drum rotates, and the combined action of washing powder and water is used for washing clothes cleanly. Of course, the washing machine may be of other types, and the embodiments of the present application are not to be construed as limiting the types of washing machines, and are described herein by way of example only in relation to drum-type washing machines. The washing machine comprises an inner cylinder and an outer cylinder sleeved outside the inner cylinder, wherein the inner cylinder and the outer cylinder are coaxially arranged, and the inner cylinder can rotate relative to the outer cylinder. The inner cylinder is used for bearing clothes, the outer cylinder is used for containing washing water, for example, the inner cylinder can be provided with water holes, water in the outer cylinder enters the inner cylinder through the water holes of the inner cylinder, and washing of the clothes is achieved under the cooperation of rotation of the inner cylinder and laundry detergent. The washing machine is not limited to the above parts, and may further include a casing, a display panel, a motor, a shaft, and the like, which are not described herein. The control method of the washing machine comprises the following steps:

101. after the washing is completed, the clothes are taken out, and whether the washing is barrel cleaned or not is judged.

Because there is the clearance between inner tube and the urceolus, the water in the urceolus passes through the process of water hole entering in the inner tube of inner tube, and the water in the inner tube passes through its water hole entering in the urceolus, or wash water in the process of channeling between inner tube and urceolus, the dirt that drops on the clothing can deposit inner tube surface and/or urceolus internal surface, if not in time clear up, the dirt can be stained with on the clothing again and cause secondary pollution to the clothing.

In order to reduce the occurrence of the problems, when the cylinder is cleaned, different cleaning flushing time periods are used for different dirt accumulation amounts, the cylinder cleaning is not performed in a fixed period, the time periods of each cylinder cleaning are different, and the cylinder cleaning effect can be improved.

For example, it may be determined whether to perform drum cleaning for the present washing after the washing is completed and the laundry is taken out. It will be appreciated that cleaning of the drum during the washing process, if not timely discharged, tends to cause secondary pollution to the laundry. Thus, the cleaning of the drum according to the embodiments of the present application is performed after the washing is completed and the laundry is taken out, and the drum can be directly cleaned without considering the problem of contaminating the laundry.

Wherein, the washing is completed to take out the clothes, which can be performed by setting an automatic detection program of the washing machine. For example, detecting whether the inner cylinder is in an empty cylinder state, if so, further judging whether the door is closed, and if the user selects cylinder cleaning after the door is closed, performing a cylinder cleaning process; if the user does not select the cylinder cleaning, the cylinder cleaning is not performed, but the washing time for cleaning the inner cylinder and the outer cylinder required by the washing is calculated so as to refer to the subsequent cylinder cleaning time, or the subsequent cylinder cleaning time can compensate the time for which the cleaning is not performed.

In some embodiments, the washing machine may be programmed to perform an indefinite period of tub cleaning, for example, after the last tub cleaning, the next tub cleaning may be automatically performed three times after washing, the third tub cleaning may be automatically performed after washing, for example, six times, and the cleaning time period of each tub cleaning is not equal.

102. If so, controlling the water level in the outer cylinder to reach the clean water level, and controlling the inner cylinder to rotate so as to drive water flow to agitate between the inner cylinder and the outer cylinder to wash the outer surface of the inner cylinder and the inner surface of the outer cylinder.

If the cleaning of the drum is needed, controlling the water level in the outer drum to reach the cleaning water level, and controlling the inner drum to rotate under the cleaning water level so as to drive water flow to agitate between the inner drum and the outer drum to wash the outer surface of the inner drum and the inner surface of the outer drum. It can be understood that the inner cylinder is controlled to rotate, and in the rotating process of the inner cylinder, water flow can be driven to surge between the inner cylinder and the outer cylinder to flush the outer surface of the inner cylinder and the inner surface of the outer cylinder. Under the cleaning water level, the water flow is driven to make cutting movement by the rotation of the inner cylinder so as to clean the cylinder.

The inner cylinder rotation speed can be higher rotation speed such as rotation speed larger than or equal to 80rpm, and the centrifugal force is larger than the pressure of water in the outer cylinder to the inner cylinder pressure, so that water in the outer cylinder can be reduced from entering the inner cylinder, and dirt is reduced from entering the inner cylinder.

103. If not, the washing time for cleaning the inner cylinder and the outer cylinder required by the washing is calculated.

If the cylinder does not need to be cleaned, the washing time length for cleaning the inner cylinder and the outer cylinder, which is required by the washing, is calculated so as to compensate the washing time length when the subsequent cylinder is cleaned, and the dirt amount is matched with the proper washing time length, so that the cleaning effect of the cylinder is improved.

According to the control method of the washing machine, the drum is cleaned after washing is completed, so that the influence of dirt on the cleanliness of clothes can be reduced; in addition, the cylinder cleaning program does not run in a fixed period, so that the amount of deposited dirt can be cleaned in a targeted manner, and the cleaning effect is improved.

For the calculation of the flushing time, the following manner may be adopted:

for the washing time period of the drum cleaning, the washing time period for washing the outer surface of the inner drum and the inner surface of the outer drum may be determined according to at least one of the laundry weight, the laundry material in the inner drum, and the washing time period of the main washing stage. It should be noted that, the dirt between the inner cylinder and the outer cylinder is mainly formed by fiber deposition falling off from the clothes, and the fiber falling-off amounts corresponding to different weights of the clothes are different; different clothes materials correspond to different washing mechanical forces, the fiber shedding amounts corresponding to the different washing mechanical forces are also different, for example, the washing mechanical forces of cotton-flax washing and four-piece washing procedures are different, and the washing force is determined according to the clothes materials when the washing procedures are designed; the washing time also determines the fiber falling amount, and the longer the washing time is, the larger the fiber falling amount is. Accordingly, the washing time period of the drum cleaning may be determined according to at least one of the laundry weight, the laundry material, and the washing time period of the main washing stage within the drum.

The weight of the clothes, the material of the clothes and the washing time of the main washing stage can be determined before washing, for example, after the clothes are put into the inner drum, the clothes can be weighed to obtain the weight of the clothes. For another example, when the user selects a washing course such as cotton-flax washing or four-piece washing, or a sensor such as a camera is provided to photograph, the laundry material may be determined, and the washing time period of the main washing course may be calculated according to the set course. Thus, the length of time for flushing the outer surface of the inner drum and the inner surface of the outer drum can be determined before the start of the washing.

There are at least three ways in which embodiments of the present application determine the flush time for cartridge cleaning, each of which is described below.

In the first way, the washing time of the drum cleaning is determined according to the laundry weight. For example, the weight of the laundry in the inner drum is obtained, and if the weight of the laundry is within the preset weight range, the first washing time period t1 is calculated according to the weight WF1 of the laundry, the standard weight WF0, the washing time period t0 corresponding to the standard weight, and the first coefficient k1, for example, t1=k1×wf1/wf0×t0. Wherein the laundry weight WF1 can be obtained according to the weighing. The standard weight WF0 may be determined according to experiments, for example, different laundry materials are set under the same laundry weight, and the standard weight WF0 is calibrated for each laundry material. For example, the standard weight WF0 may be set according to the load half load of cotton, such as a model of 10kg calibrated to 5 kg. The flush time t0 is determined based on a standard weight, also referred to as a standard flush time, and can be obtained from multiple experiments. The first coefficient k1 is a parameter coefficient that is adjusted in time according to the material of the clothes, for example, k1 corresponding to the clothes made of cotton is 1, k1 corresponding to the clothes made of chemical fiber is a value ranging from 0.6 to 1, k1 corresponding to the clothes made of large materials is a value ranging from 0.8 to 1.5, k1 corresponding to the clothes made of down jackets is a value ranging from 0.4 to 0.8, and k1 corresponding to the clothes made of outdoor jackets is a value ranging from 0.3 to 0.7.

In some embodiments, the first washing time period may also be calculated according to the laundry weight, the standard weight, and the washing time period corresponding to the standard weight, and the calculation rule is similar to the above case, and the calculation may be referred to above, which is not repeated here.

And if the weight of the clothes is out of the preset range, selecting a first flushing time length according to the set weight. It can be understood that, since the laundry weight exceeds the preset range, the calculation cannot be performed according to the above formula, and therefore the first flushing time period can be selected by the set weight, for example, a mapping table can be set, the first flushing time period is exceeded in the preset range and corresponds to one flushing time period in the first range, the second flushing time period is exceeded in the preset range and corresponds to the other flushing time period in the second range, and so on to determine the first flushing time period.

In a second way, the duration of the flushing of the cartridge cleaning is determined on the basis of the duration of the washing in the main washing phase. For example, the washing time t3 of the main washing stage, the material of the laundry in the inner drum, the first coefficient k1 adjusted in time according to the material of the laundry, the second coefficient k2 adjusted in time according to the main washing stage, and the rinsing compensation time t4 may be obtained, and the second rinsing time t2 is calculated according to the washing time t3, the first coefficient k1, the second coefficient k2, and the rinsing compensation time t4, for example, t2=k1×k2×t3+t4. The washing time t3 of the main washing stage can be obtained according to a set program after the material of the clothes is determined. The first coefficient k1 and the second coefficient k2 are coefficients for time adjustment according to different parameters, for example, k1 corresponding to cotton-made clothes is 1, k1 corresponding to chemical fiber-made clothes is a value ranging from 0.6 to 1, k1 corresponding to large-sized clothes is a value ranging from 0.8 to 1.5, k1 corresponding to down jackets is a value ranging from 0.4 to 0.8, and k1 corresponding to jacket-made clothes is a value ranging from 0.3 to 0.7. For example, k2 may range from 0.015 to 0.2. The flush offset time period t4 is an offset value for the flush time period to adequately clean the cartridge, for example, the flush offset time period t4 ranges from 30 seconds to 2 minutes.

The determination of the second washing time period is not limited to the above manner, and for example, the second washing time period may be calculated from the washing time period of the main washing stage. For another example, the second washing time period may be calculated based on the washing time period of the main washing stage, the first coefficient, and the second coefficient.

In a third way, the washing time period of the drum cleaning is determined jointly from the laundry weight and the washing time period of the main washing stage. For example, a first washing time t1 calculated according to the weight of clothes in the inner cylinder and a second washing time t2 calculated according to the washing time of the main washing stage are obtained, a third washing time t6 is obtained according to the first washing time t1 and the second washing time t2,

wherein b1 is a coefficient that is time-adjusted according to the weight of the laundry, for example, b1 has a value ranging from 0.01 to 2. b2 is a coefficient which is time-adjusted according to the washing duration of the main washing stage, for example, the value of b2 ranges from 0.1 to 1.5. The third flushing period t6 may also be calculated using a linear equation.

According to the method and the device for cleaning the drum, the washing time length for cleaning the drum is determined according to at least one of the weight of the clothes, the material of the clothes and the washing time length of the main washing stage, and the fiber shedding amount of the clothes can be accurately determined, so that the proper washing time length is formulated according to the fiber shedding amount, deposition of dirt is reduced, and the cleaning effect of the drum is improved.

If the cylinder needs to be cleaned, calculating the cleaning time of the cylinder cleaning.

For example, referring to fig. 2, fig. 2 is a schematic diagram illustrating a second flow of a control method of a washing machine according to an embodiment of the present application. The embodiment of the application also provides a control method of the washing machine, which comprises the following steps:

201. and acquiring the accumulated duration of accumulated non-executed flushing before the current washing.

The drum can be continuously cleaned, i.e. after each wash is completed, the cumulative length of time between the washes when no rinse is performed can be 0, and if the wash is performed this time, the cumulative length is not counted.

If the cylinder is not cleaned continuously, the accumulated time length of the non-cleaning cylinder can be added into the cleaning time length of the cleaning cylinder so as to supplement the cleaning of the inner cylinder and the outer cylinder, and the corresponding cleaning time length is set for different dirt amounts instead of uniformly cleaning by adopting the fixed time length, so that the cleaning effect of the cylinder can be improved.

For example, if the cartridge cleaning is not continuously performed, the flushing time period for which the cartridge cleaning is required each time may be recorded, and the accumulated time period is continuously accumulated to be added to the subsequent cartridge cleaning time period.

202. And determining the cleaning time length of the cylinder cleaning according to the required flushing time length and the accumulated time length.

The required flushing time length is calculated according to the fiber shedding amount of the current washing, the accumulated time length is the sum of the multiple flushing time lengths of the previous uncleaned cylinder, and the accumulated time length can be calculated according to the fiber shedding amount of each washing. The cleaning time of the cylinder can be the sum of the flushing time and the accumulated time, so that the fiber fallen off in the current washing can be removed, and the residual fiber or dirt in the previous washing can be removed, so that the dirt is accurately removed, the residue and the deposition of the dirt are reduced, and the cleaning effect is improved.

203. And flushing the outer surface of the inner cylinder and the inner surface of the outer cylinder according to the cleaning time.

The outer surface of the inner barrel and the inner surface of the outer barrel can be washed by the movement of water flow driven by the rotation of the inner barrel, and the inner barrel can be controlled to rotate, so that the water flow can be driven to agitate between the inner barrel and the outer barrel to wash the outer surface of the inner barrel and the inner surface of the outer barrel in the rotating process of the inner barrel. Under the cleaning water level, the water flow is driven to make cutting movement by the rotation of the inner cylinder so as to clean the cylinder.

Wherein the inner barrel rotational speed may be a higher rotational speed such as a rotational speed of greater than or equal to 80rpm, at which time water in the outer barrel may be reduced from entering the inner barrel.

The outer surface of the inner cylinder and the inner surface of the outer cylinder are washed according to the cleaning time length, so that the washed shedding fibers can be cleaned, deposited dirt can be removed according to the accumulated time length, the deposition of the dirt is reduced, and the cleaning effect can be improved.

According to the control method of the washing machine, the accumulated time length of the drum cleaning is counted into the cleaning time length of the drum cleaning, namely, the previous dirt can be cleaned, the residue of the dirt is reduced, and therefore the cleaning effect is improved.

The cleaning duration may not be increased, for example, the working duration of the washing program may be obtained, and the running duration of the rinsing stage may be adjusted according to the cleaning duration and the working duration. For example, the washing process may include a main washing stage, a rinsing stage, and a dehydrating stage. In the main washing stage, the rotation of the inner cylinder disturbs water, and the water is combined with the detergent dissolved in the water to jointly act on clothes so as to realize the washing of the clothes. The rinsing stage, namely the stage of removing detergent foam, can be used for rinsing for a plurality of times to continuously discharge foam, so as to reduce the illusion that the foam forms residues on clothes to cause the washout of the clothes. The dehydration stage is a process of throwing out moisture in the laundry. For example, the cleaning duration of the cartridge cleaning may be compensated by shortening the run duration of the rinse phase so that the cleaning duration does not take up additional time.

In the process of cleaning the inner cylinder and the outer cylinder, the cleaning water level in the outer cylinder can be maintained in dynamic balance so as to continuously discharge dirt, thereby improving the cleaning effect of the cylinder.

For example, please refer to fig. 3 in combination with fig. 1 and fig. 2, fig. 3 is a schematic third flow chart of a control method of a washing machine according to an embodiment of the present application. The embodiment of the application also provides a control method of the washing machine, which comprises the following steps:

301. water is introduced into the inner tub while water in the outer tub is discharged to maintain the water level in the outer tub at a clean water level.

According to the embodiment of the application, the cleaning water level is controlled to maintain dynamic balance, namely, water is discharged while water is fed, dirt is discharged continuously, and the cleaning effect on the cylinder is improved.

For example, water may be introduced into the inner tub while water in the outer tub is discharged to maintain the water level in the outer tub at a clean water level. The water inlet into the inner cylinder can be realized by spraying water. It can be appreciated that, can be provided with water intaking valve and spray valve in the washing machine, the water intaking valve is opened and can be to the urceolus in, spray valve is opened and can be to interior section of thick bamboo in spray water, like in the rinsing process, spray mouthful spray water in the inner tube, can get rid of the at least partial foam on the clothing, in order to improve foam removal rate, this application embodiment adopts spray water to go on with intaking simultaneously, for example, the velocity of flow of spray water can be the same with the velocity of flow of intaking, thereby the synchronous steady growth of water of inner tube and urceolus, in order to reduce the phenomenon that the water that has the dirt in the urceolus flows into in the inner tube, thereby reduce secondary pollution to the clothing.

The water in the outer cylinder can be discharged by pumping water to a water outlet of the washing machine when the drainage pump is started, and the water level in the outer cylinder cannot reach the cleaning water level easily if the water is always discharged because the flow rate of the inlet water and the drainage flow rate are generally unequal, so that the cleaning effect on the inner cylinder and the outer cylinder is affected. Accordingly, a drain timing may be provided to the drain pump such that the water level in the outer tub is maintained at the cleaning water level.

For example, a first water inflow rate of the inner tub and a second water inflow rate of the outer tub may be acquired, and a drain timing of opening and closing the drain pump may be set according to the first water inflow rate and the second water inflow rate. For example, the first water inlet flow rate and the second water inlet flow rate can be equal, so that water in the inner cylinder flows to the outer cylinder, and the probability that water with dirt between the inner cylinder and the outer cylinder flows to the inner cylinder is reduced. For another example, the first water inlet flow rate can be larger than the second water inlet flow rate, and the probability of the water with dirt between the inner cylinder and the outer cylinder flowing to the inner cylinder can be reduced, so that secondary pollution to clothes is reduced. Because the first water inlet flow rate is greater than or equal to the second water inlet flow rate, the first water inlet flow rate according to the inner barrel can be used as a reference coefficient of the water inlet flow rate.

In an exemplary embodiment, if the first water inflow velocity is greater than or equal to the set flow velocity, the drain pump is controlled to be turned on and off according to the first on/off ratio. Wherein, the set flow rate may be a drain flow rate. If the second water inlet flow rate is smaller than the set flow rate, the drainage pump is controlled to be started and closed according to a second start-stop ratio, and the second start-stop ratio is smaller than the first start-stop ratio. The on-off ratio is the ratio of the opening time length and the closing time length of the drainage pump, and a plurality of on-off ratios arranged at intervals can form a drainage time sequence. It should be noted that, the drain time sequence of the drain pump is set according to the inflow velocity, if the inflow velocity is faster, the drain pump is opened for a longer time; if the flow rate of the water inlet is slower, the opening time of the drainage pump is shorter, so that the amount of the water inlet and the amount of the water outlet in unit time are kept consistent, the cleaning water level in the outer cylinder is kept in dynamic balance, on one hand, the inner cylinder can be ensured to rotate the water with the cleaning water level to make cutting movement to clean the cylinder, on the other hand, dirt can be continuously discharged, the problem that the dirt is deposited on the cylinder and is difficult to clean is solved, and the cleaning effect is improved.

In some embodiments, the drain timing of the opening and closing of the drain pump may also be set by the rate of change of the water level in the tub. For example, the change rate of the water level in the outer cylinder is obtained, calculation can be performed by the height change of the water level in a set time period, and the drain time sequence for opening and closing the drain pump is set according to the change rate. For example, if the water level changes rapidly, the water discharge time sequence can be quickened, namely the on-off ratio is increased; if the water level changes slowly, the water draining time sequence can be slowed down, namely the on-off ratio is reduced.

It should be noted that, through optimizing the control timing sequence of the drain pump and controlling according to the combination of water level control and fixed timing sequence, the phenomenon that the clean water level is too low or too high due to the too high water level fluctuation in the high-speed rotation process can be avoided, and the flushing effect is affected.

302. The inner cylinder is controlled to rotate so as to drive water flow to agitate between the inner cylinder and the outer cylinder to wash the outer surface of the inner cylinder and the inner surface of the outer cylinder.

The outer surface of the inner barrel and the inner surface of the outer barrel can be washed by the movement of water flow driven by the rotation of the inner barrel, and the inner barrel can be controlled to rotate, so that the water flow can be driven to agitate between the inner barrel and the outer barrel to wash the outer surface of the inner barrel and the inner surface of the outer barrel in the rotating process of the inner barrel. Under the cleaning water level, the water flow is driven to make cutting movement by the rotation of the inner cylinder so as to clean the cylinder. Wherein the inner barrel rotational speed may be a higher rotational speed such as a rotational speed greater than or equal to 80rpm to reduce water in the outer barrel from entering the inner barrel.
