Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The washing method of drum washing machine is designed by simulating the principle of beating clothes by hammer, and is characterized by that it is made up by using stainless steel internal cylinder, mechanical program controller, shell with triple protection of phosphating, electrophoresis and spraying and several heavy cement blocks, and adopting the combined action of washing powder and water to make the clothes be washed completely. That is, the inner cylinder of the drum washing machine is in a horizontal type, the opening of the inner cylinder faces to the horizontal direction, the inner cylinder can rotate around the axis of the horizontal direction, and the lifting ribs in the inner cylinder are combined to drive clothes to turn over, so that the clothes are uniformly washed or dried.

In order to reduce the eccentric condition of clothes in the dehydration process and improve the probability of the highest rotation speed of the inner cylinder in the dehydration process and further improve the dehydration efficiency, an embodiment of the application provides a drum washing machine and a control method thereof, and the description is given below with reference to the accompanying drawings.

With the improvement of the functional requirements of users on the washing machine, the structure of the washing machine is greatly improved. For example, in the embodiment of the application, the drum washing machine comprises an inner drum and a base, the inner drum is used for bearing clothes, the inner drum is provided with a front end close to a door body of the drum washing machine and a rear end opposite to the front end, and the rear end of the inner drum is rotatably connected with the base so as to drive the front end of the inner drum to turn over towards a direction away from or close to the base. It should be noted that, the rotatable connection between the rear end of the inner cylinder and the base is not that the rear end of the inner cylinder is directly connected with the base, for example, the inner cylinder can be rotatably connected with the base through a box body of a drum washing machine, and the inner cylinder is arranged in the box body and can be turned over according to the turning of the box body. The base can raise the inner tube on the one hand, and on the other hand can provide the inner tube and support when the inner tube overturns. In order to improve the stability of the inner cylinder rotation, a supporting rod can be further arranged, and the supporting rod supports the box body and the inner cylinder when the box body and the inner cylinder are overturned, so that the running stability of the inner cylinder is improved.

Referring to fig. 1, fig. 1 is a schematic flow chart of a control method of a drum washing machine according to an embodiment of the application. The embodiment of the application provides a control method of a drum washing machine, which comprises the following steps:

101. in the dehydration stage, a first eccentricity value of the laundry in the drum is obtained.

In the dehydration stage, the inner barrel is eccentric, namely clothes are concentrated in a certain area of the inner barrel, so that the inner barrel cannot increase the rotating speed, and the inner barrel rotates at the stage, because the eccentric inner barrel can cause the inner barrel to strike the outer barrel in the box body, a part of energy can be lost when the inner barrel strikes the outer barrel, and the inner barrel cannot increase the rotating speed. The inner drum is operated at a high rotational speed to spin off the water in the laundry by centrifugal force, thereby dehydrating the laundry. And when eccentric, the inner cylinder can only dehydrate clothes at a low rotation speed, so that the dehydration efficiency can be influenced, and the use experience of a user is reduced.

Therefore, in the dehydration stage, the eccentricity value of the laundry in the inner drum needs to be paid attention to so as to adjust when the laundry is eccentric, thereby reducing the eccentricity of the laundry, improving the probability of high speed in dehydration, and further improving the dehydration rate.

In the dehydration stage, the first eccentric value of the clothes in the inner cylinder is obtained, and the obtaining mode can be that an eccentric detection device is arranged below the inner cylinder, wherein the eccentric detection device can comprise a plurality of detection parts which are arranged at intervals, and the detection parts are distributed from the front end to the rear end of the inner cylinder so as to correspondingly detect the weights of different positions of the inner cylinder. The first eccentricity value of the laundry in the inner tub is obtained by comparing the plurality of weight values of the inner tub detected by the plurality of detecting portions.

The first eccentricity value may be obtained by an image method, by acquiring an image of the laundry in the drum, and calculating a ratio of the laundry to the drum area based on the image.

The first eccentric value may also be determined by detecting a distance of the inner barrel shifted in the gravity direction, for example, when it is detected that the front end of the inner barrel is shifted in the gravity direction relative to the rear end by more than a set shift amount, the first eccentric value is selected from a pre-stored table of shift amounts and eccentric values.

Of course, the manner of acquiring the eccentricity value is not limited to the above-described manner, and the above-described is merely illustrative, and should not be construed as limiting the manner of acquiring the eccentricity value.

102. When the first eccentric value is larger than the first eccentric threshold value, the front end of the inner cylinder is controlled to turn over towards the direction away from the base, and the inner cylinder is controlled to rotate so as to shake off clothes.

When the first eccentricity value exceeds the first eccentricity threshold value, the fact that the eccentricity condition of clothes in the inner cylinder is severe at the moment is shown, the inner cylinder can not shake and scatter through normal control of forward rotation and reverse rotation of the inner cylinder in an alternating mode, and under the condition, shake and scatter can be conducted through control of the inner cylinder overturning mode.

The first eccentricity threshold may be obtained by experimental measurement, for example, eccentricity values corresponding to various eccentricity conditions are set, and an average value or a weighted average value of the eccentricity values is taken as the first eccentricity threshold.

The front end of the inner cylinder is controlled to turn over towards the direction away from the base, and the box body can be driven to rotate by the motor, so that the inner cylinder is driven to turn over, the intelligent degree of the drum washing machine can be improved, namely, the turning-over type eccentric adjustment is automatically carried out after the eccentric value is detected. Of course, the front end of the control inner barrel can be turned towards the direction away from the base in a manual mode, namely, the box body is turned over by using external force so as to drive the inner barrel to turn over, and a user can control the box body to turn over at any angle, so that the control flexibility is improved, and the user experience is improved. When the box body and the inner barrel are turned over, a similar buckle mode can be arranged to remind a user of turning over the angle grade, and the user can conveniently refer to the box body and the inner barrel.

After the inner cylinder is turned to a set angle, the inner cylinder is controlled to rotate so as to shake off clothes. It can be understood that for eccentric clothes, the inner cylinder is turned over, so that the clothes eccentric to the front end of the inner cylinder can be moved backwards, and the eccentricity in the direction of the rear end of the front end of the inner cylinder is reduced; on the basis, the inner drum is controlled to rotate, for example, the inner drum can alternately rotate positively and reversely to shake off the clothes, so that the eccentricity of the clothes on the circumferential wall of the inner drum is reduced.

103. And controlling the inner cylinder to be aligned, and obtaining a second eccentric value of the clothes in the inner cylinder after shaking and scattering.

After the inner cylinder is overturned and rotated to shake and scatter, the inner cylinder is controlled to be righted, namely the initial state that the front end and the rear end of the inner cylinder are flush is restored.

And acquiring a second eccentric value of the clothes in the inner cylinder after shaking, namely verifying whether the overturning and rotating shaking of the inner cylinder are effective in improving the eccentric condition, and if the improvement is less, shaking again by overturning again and rotating, or shaking again by adjusting the overturning angle so as to reduce the eccentric value of the clothes.

The second eccentricity value may be acquired in the same manner as the first eccentricity value.

For example, the eccentric detection device can be arranged below the inner cylinder, and the eccentric detection device can comprise a plurality of detection parts which are arranged at intervals and distributed along the front end to the rear end of the inner cylinder so as to correspondingly detect the weight of different positions of the inner cylinder. The second eccentric value of the clothes in the inner cylinder after shaking is obtained by comparing the weight values of the inner cylinder detected by the detection parts.

For another example, the first eccentricity value may be obtained by an image method, and the second eccentricity value after shaking is obtained by collecting an image of the laundry in the inner drum and calculating the ratio of the laundry to the inner drum area according to the image.

For example, the second eccentric value may be determined by detecting a distance of the inner cylinder shifted in the gravity direction, for example, when it is detected that the front end of the inner cylinder is shifted in the gravity direction with respect to the rear end by more than a set shift amount, the second eccentric value is selected from a pre-stored table of shift amounts and eccentric values.

There may be other ways of obtaining the second eccentricity value, which are not exemplified here.

104. When the second eccentricity value is smaller than or equal to the second eccentricity threshold value, controlling the inner cylinder to rotate at the first rotation speed so as to dehydrate clothes in the inner cylinder; the second decentration threshold is less than or equal to the first decentration threshold.

When the second eccentricity value is less than or equal to the second eccentricity threshold value, the eccentricity condition in the inner cylinder is improved greatly, and in this case, the high-speed dewatering action on the inner cylinder can be performed to improve the dewatering efficiency.

It can be understood that, since the first eccentric threshold corresponds to an eccentric value when the laundry is not shaken, and the second eccentric threshold corresponds to an eccentric value that can be dehydrated at a high speed, the two eccentric values are in different states, and the parameters can be selected to be the same or different.

For example, the second eccentricity threshold may be smaller than the first eccentricity threshold, that is, the eccentricity value when the shake-out is performed at the upper speed is smaller than the eccentricity value when the shake-out is not performed, so as to distinguish, and improve the accuracy of control.

For another example, the second eccentricity threshold may be the same as the first eccentricity threshold, so that the eccentricity value is unified for high speed on dehydration, that is, the high speed can be achieved only if the eccentricity value is smaller than the second eccentricity threshold, and the control logic is simple.

When the second eccentricity value is smaller than or equal to the second eccentricity threshold value, the inner cylinder is controlled to rotate at the first rotation speed so as to dehydrate clothes in the inner cylinder. The first rotational speed may be a maximum rotational speed, such as 1400rpm; the first rotational speed may also be a second highest rotational speed, such as 1200rpm. For example, when the second eccentricity value is less than or equal to the second eccentricity threshold, that is, the eccentricity value is within a reasonable range, the highest rotation speed may be tried to perform rotational dehydration at first; if the highest rotation speed dehydration is unsuccessful, the next highest rotation speed is selected for dehydration. For another example, the inner cylinder may be controlled to dewater at a second higher rotational speed when the adjusted second eccentricity value is still greater than the second eccentricity threshold.

After the shaking adjustment is performed, the probability of high speed on the inner cylinder can be improved instead of dehydration at a low rotation speed such as 800rpm, and the dehydration efficiency can be improved.

In the control method of the drum washing machine provided by the embodiment of the application, when the first eccentric value of the clothes in the inner drum exceeds the first eccentric threshold value in the dewatering process of the washing machine, the front end of the inner drum is controlled to turn over in the direction away from the base, and the inner drum is controlled to rotate at the same time, so that the clothes in the inner drum are shaken and scattered, the eccentric condition of the clothes is reduced, the probability of high speed on the inner drum in dewatering can be improved, the low speed dewatering can be carried out instead of the condition that the upper speed cannot be increased due to the eccentricity, the dewatering efficiency can be improved, and the user experience is improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of a control method of a drum washing machine according to an embodiment of the application. The embodiment of the application also provides a control method of the drum washing machine, which comprises the following steps:

201. in the dehydration stage, a first eccentricity value of the laundry in the drum is obtained.

202. Determining the overturning angle and/or the overturning times of the front end of the inner barrel in the direction away from the base according to the first eccentric value, wherein the overturning angle is positively correlated with the first eccentric value, and the overturning times are positively correlated with the first eccentric value; and the inner cylinder is controlled to rotate at a second rotating speed so as to shake and scatter clothes, and the second rotating speed is inversely related to the first eccentric value.

In the embodiment of the application, the overturning angle and/or the overturning times of the front end of the inner cylinder in the direction away from the base can be determined according to the first eccentric value, that is, the overturning angle and/or the overturning times of the inner cylinder can be controlled corresponding to different first eccentric values.

For example, the overturning angle of the inner cylinder can be determined according to the first eccentric value, that is, the overturning angle is positively correlated with the first eccentric value, that is, the larger the first eccentric value is, the more serious the clothes are eccentric at the moment, so that the probability that the clothes move from the front end to the rear end of the inner cylinder can be increased by increasing the overturning angle of the inner cylinder, and the shaking probability of the clothes can be increased.

For example, the number of times of turning the inner cylinder can be determined according to the first eccentric value, and the number of times of turning is positively correlated with the first eccentric value, that is, the larger the first eccentric value is, the more serious the degree of eccentricity of the clothes at this time is, so that the probability of shaking the clothes can be improved by gradually shaking the number of times of turning the inner cylinder.

For another example, the overturning angle and the overturning times of the inner cylinder can be determined according to the first eccentric value, that is, the greater the first eccentric value is, the more serious the clothes are eccentric at the moment, and the probability that the clothes move from the front end to the rear end of the inner cylinder can be increased by increasing the overturning angle of the inner cylinder; in addition, the turnover times can be increased at the same time to gradually shake and scatter, so that the probability of shaking and scattering clothes is improved.

The second rotational speed of the inner cylinder during the turning can also be determined from the first eccentricity value, the second rotational speed being inversely related to the first eccentricity value. That is, in case that the inner drum is turned over, the larger the first eccentricity value is, the smaller the second rotation speed at which the inner drum rotates is, to shake the laundry with slow shaking.

In addition, the alternating frequency of the forward rotation and the reverse rotation of the inner cylinder can be determined according to the first eccentric value, for example, the alternating frequency of the forward rotation and the reverse rotation of the inner cylinder can be positively correlated with the first eccentric value, that is, the larger the first eccentric value is, the larger the alternating frequency of the forward rotation and the reverse rotation of the inner cylinder is, so that the clothes can be shaken off through the high-frequency forward rotation and the reverse rotation alternation.

203. And controlling the inner cylinder to return to the normal position.

204. The inner cylinder is controlled to rotate in a preset mode so as to eccentrically adjust clothes in the inner cylinder.

205. And acquiring a second eccentric value after eccentric adjustment of the clothes in the inner cylinder.

Regarding steps 203 to 205:

After the inner cylinder is aligned, if the second eccentric value is directly detected, at this time, a small amount of clothes is gathered due to the alignment of the inner cylinder, and the second eccentric value is larger. In order to reduce this, the eccentricity of the inner cylinder may be adjusted to reduce the eccentricity of the inner cylinder after the inner cylinder is returned to the normal position and before the second eccentricity value is obtained.

For example, the drum can be controlled to rotate in a preset manner to eccentrically adjust the laundry in the drum. The preset mode can be that the forward rotation and the reverse rotation of the set frequency are alternately operated, and the set inner cylinder rotation speed is used for shaking clothes through the alternation of the forward rotation and the reverse rotation. It can be understood that the overturning inner cylinder can at least partially disassemble and scatter the wound clothes, and the inner cylinder is reset and then shake and scatter the clothes collected during overturning, so that the two times of shake and scatter or eccentric adjustment can reduce the eccentric condition of the clothes, and the high-speed probability in dehydration is improved, thereby improving the dehydration efficiency.

And acquiring a second eccentric value of the clothes in the inner cylinder after the eccentric adjustment, namely verifying whether the overturning and the rotating shaking of the inner cylinder are effective for improving the eccentric condition, if the improvement is less, shaking again by overturning again and rotating, or shaking again by adjusting the overturning angle, so as to reduce the eccentric value of the clothes.

206. When the second eccentricity value is smaller than or equal to the second eccentricity threshold value, controlling the inner cylinder to rotate at the first rotation speed so as to dehydrate clothes in the inner cylinder; the second decentration threshold is less than or equal to the first decentration threshold.

In the control method of the drum washing machine provided by the embodiment of the application, when the first eccentric value of the clothes in the inner drum exceeds the first eccentric threshold value in the dewatering process of the washing machine, the front end of the inner drum is controlled to turn over in the direction away from the base, and the inner drum is controlled to rotate at the same time, so that the clothes in the inner drum are shaken and scattered, the eccentric condition of the clothes is reduced, the probability of high speed on the inner drum in dewatering can be improved, the low speed dewatering can be carried out instead of the condition that the upper speed cannot be increased due to the eccentricity, the dewatering efficiency can be improved, and the user experience is improved. And moreover, the overturning angle and/or the overturning times of the inner cylinder can be determined according to the eccentric value, so that the eccentric adjustment is more accurate, and the efficiency of the eccentric adjustment can be improved.

Referring to fig. 3, fig. 3 is a schematic view illustrating a third flow of a control method of a drum washing machine according to an embodiment of the application. The embodiment of the application also provides a control method of the drum washing machine, which comprises the following steps:

301. a first weight of the garment within the inner tub is obtained.

When the weight of clothes in the inner cylinder is different, the adjustment mode is also different.

For example, at the beginning of the dehydration phase, a first weight of the laundry inside the drum is obtained, which can be obtained by weighing.

It will be appreciated that the laundry dehydration process is performed after the washing process, and that different laundry materials may be washed in different washing modes before the laundry washing. After the material of the clothes is determined, the subsequent shaking adjustment mode can be used as a reference only by acquiring the first weight of the clothes in the dehydration process.

302. The load type in the inner barrel is determined according to the first weight, the load type comprises a first load and a second load, and the clothes weight of the first load is larger than that of the second load.

The type of load within the drum may be determined from the first weight, i.e. the laundry is divided into a heavy load of a larger weight, such as the first load, and a light load of a smaller weight, such as the second load, and the shaking of the heavy and light loads may take different forms.

For example, a first weight may be compared to a weight threshold, the first weight being greater than or equal to the weight threshold, and being determined as a large load, i.e., a first load, and the first weight being less than the weight threshold, and being determined as a small load, i.e., a second load.

303. When the load type in the inner cylinder is a first load and the first eccentric value is larger than the first eccentric value, the front end of the inner cylinder is controlled to overturn towards the direction away from the base, and the inner cylinder is controlled to rotate so as to shake and scatter clothes.

If the weights of clothes corresponding to the large load and the small load are different, and the same shaking or eccentric adjustment mode is adopted for the large load and the small load, for example, the normal control of the alternate running of the forward rotation and the reverse rotation of the inner cylinder is adopted, so that the shaking condition of the large load is easy to be poor; and for example, the overturning is adopted to carry out shake-out adjustment, so that excessive shake-out of small load is easily caused, and electric energy is wasted. Therefore, in order to improve the accuracy of shaking and scattering the clothes, different shaking and scattering modes are adopted for a large load and a small load.

When the load type in the inner cylinder is a first load, namely a large load, and the first eccentric value is larger than the first eccentric threshold value, the front end of the inner cylinder is controlled to turn over in a direction away from the base, and the inner cylinder is controlled to rotate so as to shake and scatter clothes.

After the inner cylinder is turned to a set angle, the inner cylinder is controlled to rotate so as to shake off clothes. It can be understood that for the clothes with large-load eccentric, the inner cylinder is turned over, so that the clothes eccentric to the front end of the inner cylinder can be moved backwards, and the eccentric in the direction of the rear end of the front end of the inner cylinder is reduced; on the basis, the inner drum is controlled to rotate, for example, the inner drum can alternately rotate positively and reversely to shake off the clothes, so that the eccentricity of the clothes on the circumferential wall of the inner drum is reduced.

For small-load clothes, namely, clothes of a second load type, the inner cylinder can be controlled to rotate in a preset mode to eccentrically adjust the clothes in the inner cylinder, and when the eccentric value of the clothes in the inner cylinder is smaller than an eccentric threshold value, the inner cylinder is controlled to rotate at a first rotating speed, wherein the first rotating speed can be the highest rotating speed or the second highest rotating speed so as to dehydrate the clothes in the inner cylinder. The preset mode can be forward rotation and reverse rotation of set frequency alternately, and set inner cylinder rotation speed, and clothes are shaken off through forward rotation and reverse rotation alternately.

According to the control method of the drum washing machine, different eccentric adjustment modes are adopted for the large load and the small load, so that the accuracy of eccentric adjustment can be improved, and the probability of high speed in dehydration and the dehydration efficiency are improved.

Referring to fig. 4, fig. 4 is a fourth flowchart of a control method of a drum washing machine according to an embodiment of the application. The embodiment of the application also provides a control method of the drum washing machine, which comprises the following steps:

401. a first weight of the garment within the inner tub is obtained.

402. The load type in the inner barrel is determined according to the first weight, the load type comprises a first load and a second load, and the clothes weight of the first load is larger than that of the second load.

403. And obtaining the water content of the clothes in the inner cylinder.

It can be understood that when the clothes have low water content, the eccentric condition in the inner cylinder is easier to adjust, and the clothes are more easily shaken out when the inner cylinder rotates due to the low water content of the clothes, namely the weight of the clothes is reduced, the fluffiness of the clothes is improved, and the clothes are more easily shaken out when the inner cylinder rotates.

The water content of the clothes in the inner drum is obtained and can be determined by the weight of the clothes before and after dehydration. For example, when the spin-drying stage is entered, a first weight m1 of the laundry in the inner tub may be obtained, and then spin-drying may be performed at a low rotational speed, such as 80rpm, to at least partially spin-out the moisture in the laundry, and then a second weight m2 of the laundry in the inner tub after the spin-drying may be obtained, and the moisture content L of the laundry in the inner tub may be determined according to the first weight m1 and the second weight m 2. For example, l= (m 1-m 2)/m 1 is 100%, that is, the amount of water thrown out by dehydration is a percentage of the first weight m1, thereby reflecting the water content of the laundry.

404. When the water content of the clothes is smaller than or equal to the water content threshold, the inner cylinder is controlled to rotate in a preset mode so as to eccentrically adjust the clothes in the inner cylinder.

When the water content of the clothes is smaller than or equal to the water content threshold, namely the water content of the clothes meets the set condition, the inner cylinder can be controlled to rotate in a preset mode so as to eccentrically adjust the clothes in the inner cylinder. The preset mode can be forward rotation and reverse rotation of set frequency alternately, and set inner cylinder rotation speed, and clothes are shaken off through forward rotation and reverse rotation alternately.

405. And if the load type in the inner cylinder is the first load, acquiring the adjustment time length or the adjustment times of the eccentric adjustment.

The subsequent adjustment of the garments within the drum can be determined based on the type of load within the drum.

If the load type in the inner cylinder is a small load, namely a second load, acquiring an eccentric value after eccentric adjustment, and when the eccentric value after eccentric adjustment is smaller than or equal to an eccentric threshold value, controlling the inner cylinder to rotate at a first rotation speed so as to dehydrate clothes. The first rotational speed is the highest rotational speed or the second highest rotational speed.

And if the load type in the inner cylinder is a large load, namely a first load, acquiring the adjustment time length or the adjustment times of the eccentric adjustment. It can be understood that, because the eccentric adjustment duration or the eccentric adjustment times corresponding to the heavy load are smaller and the load is larger, for the heavy load, the common eccentric adjustment degree is limited, and if the eccentric adjustment is always performed, the electric energy is easy to be wasted. Therefore, after the first load is eccentrically adjusted, the adjustment time length or the adjustment times of the eccentric adjustment are required to be obtained.

The timing of the adjustment period may be performed by a timer, or the count of the number of adjustments may be performed by a counter.

406. When the adjustment time length is longer than the preset time length or the adjustment times are longer than the preset times, if the adjusted eccentric value is still greater than the eccentric threshold value, the front end of the inner cylinder is controlled to turn over in the direction away from the base, and the inner cylinder is controlled to rotate so as to shake and scatter clothes in the inner cylinder.

When the adjustment time length is longer than the preset time length or the adjustment times are longer than the preset times, if the adjusted eccentric value is still greater than the eccentric threshold value, the inner cylinder is controlled to turn over and shake off, namely the front end of the inner cylinder is controlled to turn over towards the direction away from the base, and the inner cylinder is controlled to rotate so as to shake off clothes in the inner cylinder.

It can be appreciated that after the eccentric adjustment is performed on the heavy load in the conventional manner, if the eccentric threshold cannot be met yet, the eccentric adjustment manner needs to be changed, that is, the heavy load is dithered by the flipping and dithering adjustment.

According to the control method of the drum washing machine, provided by the embodiment of the application, the shaking adjustment is performed under the condition that the water content of clothes is low, so that the possibility of shaking the clothes can be improved, and further the high-speed probability in dehydration and the dehydration efficiency can be improved. In the dewatering process of the washing machine, when a first eccentric value of clothes in the inner cylinder exceeds a first eccentric threshold value, the front end of the inner cylinder is controlled to turn over in a direction away from the base, and meanwhile, the inner cylinder is controlled to rotate so as to shake and scatter the clothes in the inner cylinder, so that the eccentric condition of the clothes is reduced, the probability of high speed on the inner cylinder during dewatering can be improved, and the low-speed dewatering can be performed due to incapability of high speed caused by eccentricity, so that the dewatering efficiency can be improved, and the use experience of a user is improved.
