Description

Technical Field

The application relates to the field of laundry treatment, in particular to a method for preventing time jump of a laundry treatment process and laundry treatment equipment.

Background

The washing and drying integrated machine is a common household appliance and has washing and drying functions. When the washing is usually treated, the washing and drying integrated machine can be subjected to water inlet, washing, dehydration and drying processes. For convenience of use, the washing and drying integrated machine can calculate the total time consumed by the washing treatment according to the weight of the washing after the washing is put in, and display the total time to a user. However, since the drying time is related to the water content of the laundry, the dehydration process determines the water content of the laundry. Therefore, once the actual dehydration rotating speed cannot reach the set dehydration rotating speed due to the factors of the quantity, the materials, the types and the like of the washings in the dehydration process, the water content of the washings can be greatly increased, the drying time in actual use is far longer than the calculated time, and the user experience is reduced.

Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In accordance with embodiments of the present application, there is provided an embodiment of a method of preventing time jumps in the progress of a laundry treatment, it being noted that the steps illustrated in the flowchart of the figures may be performed in a computer system such as a set of computer executable instructions, and, although a logical sequence is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in a different order than that illustrated herein.

In general, a display screen is installed on a laundry treatment apparatus such as a dryer or a washing machine, and is used for displaying at least the remaining treatment time of the laundry, and the treatment time is estimated according to parameters such as the weight of the laundry. For the washings processing program including the drying process, because the drying time length has a larger relation with the water content of washings, once the washings are eccentric in the dehydration process or the dehydration rotating speed does not reach the target rotating speed, the actually required drying time is far longer than the estimated processing time, so that most washings processing equipment can jump the residual time on the display screen after the dehydration process is operated, and the displayed time is ensured to correspond to the actually required time. But time hopping greatly affects the user experience.

Based on this, the present embodiment provides a method for preventing time jump of the laundry processing process, as shown in fig. 1, the method includes the following steps:

s101, acquiring weight data and water absorption data of the washings to be treated.

In one embodiment, the weight data refers to the weight of the laundry to be treated, and specifically refers to the weight value obtained by weighing the laundry before the laundry treatment apparatus is fed with water. The weight data of the laundry to be treated may be obtained through power or current variation of the motor or through a sensor, which is not particularly limited in this embodiment.

In one embodiment, the water absorption data refers to the water absorption capacity of the laundry to be treated, specifically, the water absorption capacity of the laundry to be treated is small or large. When the washing to be treated absorbs a large amount of water, the washing to be treated is proved to absorb more water; when the washing to be treated absorbs a small amount of water, the washing to be treated proves to absorb a small amount of water. As to whether the amount of water absorbed is large or small, it can be obtained experimentally. For example, 2 kg of the washings to be treated are also obtained, the washings made of pure cotton can absorb 3 kg of water, and the washings made of fiber can only absorb 1 kg of water; then, the weight of the washings to be treated is changed, so that the water quantity which can be absorbed by various materials and mixed materials with each weight of washings to be treated, such as 1 kg, 3 kg and 5 kg, can be obtained. Finally, the average water absorption of the washings to be treated with the same weight and different materials can be obtained, when the average water absorption is lower than that, the washings to be treated are proved to be difficult to absorb water, and when the average water absorption is higher than that, the washings to be treated are proved to absorb a large amount of water.

S102, determining the difficulty in dewatering the washing to be treated according to the weight data and the water absorption data.

In one embodiment, the difficulty in dehydration refers to whether the laundry to be treated is easily dehydrated or difficult to dehydrate. Unlike the water absorption data, the ease of dehydration is related to the weight data. For example, when the laundry to be treated which is light in weight but high in water absorption capacity is dehydrated, eccentricity is extremely likely to occur, that is, the treatment barrel of the laundry treatment device is difficult to drive the laundry to rotate at a high speed, and at this time, the difficulty in dehydrating the laundry to be treated is difficult to dehydrate. And for the to-be-treated washings with large weight and large water absorption, eccentricity is not easy to occur when the to-be-treated washings are dehydrated, and the treatment barrel can rotate at a high speed, so that the difficulty in dehydrating the to-be-treated washings is easy to dehydrate.

And S103, when the difficulty in dehydrating the washing to be treated is difficult to dehydrate, adjusting the dehydration parameter and/or the drying parameter so as to reduce the drying time of the washing to be treated.

In one embodiment, the laundry treatment apparatus is configured with a dehydration parameter and a drying parameter when treating laundry to be treated. Wherein the dehydration parameters such as nodes of dehydration, the number of times of dehydration, the duration of a single dehydration, the time interval between adjacent dehydration, etc.; drying parameters such as the node of drying, the number of times of drying, the duration of a single drying, the temperature of drying, etc. Specifically, the dehydrated node refers to when the dehydration process is performed, and similarly, the dried node refers to when the drying process is performed, and the specific determination process is not specifically limited in this embodiment.

Since the laundry to be treated is a difficult-to-dehydrate condition, it is necessary to reduce the drying time of the laundry to be treated so that the actually required drying time is close to the initially estimated drying time. Specifically, the dehydration parameters and/or drying parameters are adjusted, for example, the dehydration times are increased, the duration of single dehydration is prolonged, the drying temperature is increased, and the like, which is not limited in this embodiment.

Through the steps, the washed matter is dehydrated once before being dried, so that the water content of the washed matter is reduced. When the dehydration difficulty of the washed object to be treated is difficult, the dehydration before drying proves that the water content of the washed object is difficult to be reduced to a target value, and at the moment, the dehydration parameters and/or the drying parameters are adjusted to reduce the drying time of the washed object to be treated, so that the difference between the actual drying time of the washed object to be treated and the time calculated and displayed at the beginning is reduced, and on one hand, the drying efficiency is ensured; on the other hand, the time displayed for the user is not easy to jump or the time for the user to wait for drying actually is not corresponding to the displayed time, so that the user experience is improved.

In another embodiment of the present application, when the difficulty in dewatering the laundry to be treated is difficult to dewater, adjusting the dewatering parameter and/or the drying parameter includes:

increasing the number of dehydration times in the dehydration parameters and changing the drying parameters based on the increased number of dehydration times to secondarily dehydrate the laundry to be treated in the drying process.

When the washing treatment equipment is used for treating the washing to be treated, the water draining, weighing, water inflow, washing, dehydration and drying are sequentially carried out. The dehydration process performed before the drying is primary dehydration, and the dehydration performed during the drying is secondary dehydration. The primary dehydration is not limited to the primary dehydration, nor is it necessarily the primary dehydration, but is named as such for the purpose of distinguishing from the secondary dehydration. The difference between the primary dehydration and the secondary dehydration is that the primary dehydration is performed before the drying and the secondary dehydration is performed after the drying, and the specific number of times of dehydration and the time period of dehydration of the primary dehydration and the secondary dehydration are not particularly limited in this embodiment.

When the secondary dehydration is performed, the laundry to be treated is dried for a while and is dehydrated once, so that even if the laundry to be treated is difficult to dehydrate, the laundry to be treated is dehydrated at this time, and eccentricity is not easy to occur. That is, the washing to be treated is rocked by the treating barrel during one-time dehydration, and is uniformly positioned in the treating barrel. The eccentricity in the primary dehydration is avoided during the secondary dehydration. After the eccentricity is reduced, the treatment barrel can drive the to-be-treated washings to rotate at a high speed more easily, the water content of the to-be-treated washings is reduced, and the drying time is greatly shortened, so that the whole treatment time of the washings is not prolonged due to the fact that the to-be-treated washings are difficult to dehydrate.

Through the above, secondary dehydration is carried out in the drying process, so that the water content of the to-be-treated washings is reduced again, the drying efficiency is ensured, the time displayed for the user is not easy to jump, and the user experience is improved. In another embodiment of the present application, the increasing the number of times of dehydration in the dehydration parameter and changing the drying parameter based on the increased number of times of dehydration to secondarily dehydrate the laundry to be treated in the drying process includes:

s201, determining a target value of the secondary dewatering rotation speed of the secondary dewatering according to the weight data of the washings to be treated.

In one embodiment, the laundry to be treated with different weights corresponds to different target values of the secondary dewatering rotation speed. In a specific scene, the target value of the secondary dehydration rotating speed is preset, and the corresponding target value of the secondary dehydration rotating speed can be obtained through weight data query.

The target value of the secondary dewatering rotation speed refers to the target rotation speed value of the treatment barrel of the washing treatment equipment when the secondary dewatering is performed, and corresponds to the actual value of the secondary dewatering rotation speed.

S202, carrying out secondary dehydration on the washings to be treated according to the target value of the secondary dehydration rotating speed.

In one embodiment, after the target value of the secondary dewatering rotation speed is obtained, the motor of the washing processing equipment can be controlled to start, the motor drives the processing barrel to rotate, the rotation speed of the processing barrel is close to the target value of the secondary dewatering rotation speed by controlling the current or the power of the motor, and when the rotation speed of the processing barrel reaches the target value of the secondary dewatering rotation speed, the running state of the motor at the moment can be maintained, so that the actual value of the secondary dewatering rotation speed reaches the target value of the secondary dewatering rotation speed.

Through the steps, the target values of the secondary dewatering rotation speeds corresponding to the washings to be treated with different weights are different, so that the reduction effect of the water content of the washings to be treated in the secondary dewatering process is improved, the drying time is shortened, and the user experience is improved.

In another embodiment of the present application, when the difficulty in dehydrating the laundry to be treated is difficult to dehydrate, the method further comprises:

and S301, reducing the primary dehydration rotating speed set value of the primary dehydration to obtain a first dehydration threshold.

In one embodiment, the primary dewatering corresponds to a preset primary dewatering speed set value. Wherein, the washings to be treated with different weights correspond to different setting values of the primary dehydration rotating speed. For example, the primary dewatering rotation speed set value can be between 800 and 1200prm for 5 kg and above of the laundry to be treated, and 600 to 800prm for below 5 kg of the laundry to be treated. The setting is specifically performed according to the operation requirement of the laundry treatment apparatus, and this embodiment is not particularly limited.

And after the set value of the primary dewatering rotation speed is reduced, obtaining a first dewatering threshold value. Wherein the decrease may be a decrease by a preset amount, such as 200prm each time, or 50prm each time; the decrease may also be to a preset target amount, such as directly to 500prm, which is not particularly limited in this embodiment.

S302, carrying out primary dehydration on the washings to be treated according to the first dehydration threshold value.

That is, the motor is controlled with the aim of increasing the rotational speed of the treatment tub to the first dehydration threshold.

Through the steps, the set value of the primary dewatering rotating speed is reduced before primary dewatering for the to-be-treated washings which are difficult to dewater, so as to obtain a first dewatering threshold value. Because the first dehydration threshold value is smaller than the primary dehydration rotating speed set value, the eccentricity of the washing to be treated in the treatment barrel is reduced, the rotating speed of the treatment barrel which is easier to reach the first dehydration threshold value is reduced, the water content of the washing to be treated is reduced, the drying efficiency is improved, and therefore the user experience is improved.

In another embodiment of the present application, after the one dewatering of the laundry to be treated according to the first dewatering threshold, the method further comprises:

S401, acquiring a primary dehydration rotating speed actual value of the primary dehydration.

In an embodiment, the actual rotational speed value of the primary dewatering process refers to the actual rotational speed value of the treatment tank in the primary dewatering process, which can be obtained through the motor power or the sensor, and the embodiment is not limited in particular.

And S402, when the primary dehydration rotating speed actual value is smaller than the first dehydration threshold value, reducing the secondary dehydration rotating speed target value.

In an embodiment, if the actual value of the primary dewatering rotation speed is still smaller than the set value of the primary dewatering rotation speed after the reduction, it is proved that the eccentricity of the washings to be treated in the treatment barrel is larger, and the target value of the secondary dewatering rotation speed is reduced at this time, so that the washings to be treated are easier to drive to rotate when the washings to be treated are subjected to secondary dewatering, the washings to be treated rotate in the treatment barrel at a lower rotation speed, and the eccentricity is gradually reduced, so that the motor can drive the treatment barrel to rotate at a rotation speed closer to the target value of the secondary dewatering rotation speed after the reduction.

Through the steps, the method is beneficial to ensuring that the to-be-treated washing can rotate along with the rotating speed of the reduced secondary dehydration rotating speed target value of the treatment barrel, so that the water content of the to-be-treated washing is reduced to the greatest extent, the drying efficiency is ensured, and the user experience is improved.

In another embodiment of the present application, after the acquiring the weight data of the laundry to be treated, the method further comprises:

and calculating the total processing time according to the weight data.

In one embodiment, the water inlet time, the washing time and the one-time dewatering time of the washing to be treated with a certain weight are all fixed, and in the same ideal case, namely, neglecting the condition that the washing to be treated is eccentric in the treatment barrel, the drying time is relatively fixed, so that the total treatment time can be determined after the weight data of the washing to be treated are obtained.

In another embodiment of the present application, the method further comprises:

when the difficulty in dehydrating the laundry to be treated is difficult to dehydrate, the total treatment time is not adjusted.

The laundry to be treated, which is difficult to dehydrate, is not dehydrated sufficiently before being dried. Therefore, the water content of the washings to be treated is high, and the drying time is prolonged by several minutes to several hours. The total processing time calculated at the beginning is shorter than the actual processing time. For some laundry treatment apparatuses, the total treatment time is adjusted, for example, the total treatment time calculated from the beginning is 40 minutes, and the total treatment time is changed to 150 minutes due to the extension of the drying time. At this time, the user waits for more than one time or even more than several times, and the user experience is greatly reduced. Since the laundry to be treated, which is difficult to dehydrate, is secondarily dehydrated in this embodiment. Therefore, the water content of the washings to be treated can be reduced during secondary dehydration, the drying time is shortened, the actual spent time is close to the total treatment time, and the user experience is ensured.

In another embodiment of the present application, the method further comprises:

when the difficulty in dehydrating the washing to be treated is easy to dehydrate, judging whether the actual value of the primary dehydration rotating speed of the primary dehydration is smaller than a minimum threshold value;

if yes, retrieving the prolonged time data from a preset time table according to the actual value of the secondary dehydration rotating speed of the secondary dehydration and the weight data;

and increasing the total processing time according to the prolonged time data, and displaying the increased total processing time.

In one embodiment, the minimum threshold is a preset value, and different weights of the laundry to be treated correspond to different minimum thresholds. For example, for more than 5 kg of the laundry to be treated, the minimum threshold is 600-800prm, for less than 5 kg of the laundry to be treated, the minimum threshold is 400-600prm, and the specific value is determined according to the actual situation, which is not particularly limited in this embodiment.

Because the difficult condition of dehydration of the washings to be treated is easy dehydration, the washings to be treated are proved to be difficult to generate eccentricity in the primary dehydration process, that is to say, the rotating speed of the treatment barrel can reach the primary dehydration rotating speed set value. However, the obtained actual value of the primary dewatering rotation speed is smaller than the minimum threshold value, and the actual value of the primary dewatering rotation speed is too small, or the actual value of the primary dewatering rotation speed is caused by the malfunction of the washing processing equipment, or the new washing to be processed is added to the processing barrel in the middle of a user, and the like. At this time, it is proved that the water content of the laundry to be treated does not reach the ideal state after one-time dehydration, that is, the water content is too high. In order to shorten the drying time, secondary dehydration is carried out, and the total treatment time is modified and displayed according to the actual value of the secondary dehydration rotating speed and the weight data.

On the one hand, when primary dehydration can be normally carried out, the condition that the rotating speed of the processing barrel is low occurs, and secondary dehydration is carried out at the moment, so that the drying time is shortened, the drying efficiency is improved, and the user experience is ensured; on the other hand, because the secondary dehydration is performed, the prolonged time data is not easy to be excessively large, and even if the total processing time is increased, the user is not easy to wait for too long, so that the user experience is ensured.

In another embodiment of the present application, if the actual value of the primary dewatering speed of the primary dewatering is smaller than the minimum threshold value, the extended time data is retrieved from the actual value of the primary dewatering speed to a preset time table. And adding the prolonged time data and the total processing time to obtain the increased total processing time for display.

Through the steps, secondary dehydration is not performed, and power consumption is saved. And displaying the increased total processing time, so that the user can know the total processing time conveniently.

In another embodiment of the present application, after the acquiring the weight data of the laundry to be treated, the method further comprises:

s701, acquiring total water inflow data.

In an embodiment, the total amount of water intake data may be obtained through a flowmeter, or may be obtained through weight detection, which is not particularly limited in this embodiment.

S702, calling a water inflow threshold according to the weight data.

In one embodiment, the laundry with different weights corresponds to a water inflow threshold, wherein the water inflow threshold is a preset value.

When the total water inflow data is smaller than or equal to the water inflow threshold value, obtaining the water absorption data as a small amount of water absorption;

and when the total water inflow data is larger than the water inflow threshold, obtaining the water absorption data as a large amount of water absorption.

In another embodiment of the present application, the determining the difficulty in dewatering the laundry to be treated according to the weight data and the water absorption data includes:

when the weight data is larger than a preset weight threshold value and the water absorption data is a small amount of water absorption, determining that the washing to be treated is difficult to dehydrate;

when the weight data is larger than a preset weight threshold value and the absorption data is a large amount of water absorption, determining that the washing to be treated is easy to dehydrate;

when the weight data is smaller than or equal to a preset weight threshold value and the water absorption data is a small amount of water absorption, determining that the washing to be treated is easy to dehydrate;

And when the weight data is smaller than or equal to a preset weight threshold value and the water absorption data is a large amount of water absorption, determining that the washing to be treated is difficult to dehydrate.

In another embodiment of the present application, the secondary dewatering is thermal dewatering.

For ease of understanding, a method of preventing time hopping of the laundry processing course will be described by taking a washing machine as an example, as shown in fig. 2.

After the washing machine is started, water is discharged.

The laundry put into the treatment tub is weighed to obtain weight data. The water consumption is obtained in various modes, the water consumption can be obtained through weight and temperature, and the simplest flowmeter is selected in the flow chart.

The expected run time, i.e. the total processing time, is displayed on the basis of the weighing values. While displaying the time correction at a later time.

And then the operation is finished until the water supplementing stage is finished. Wherein, the water inlet of the washing machine is determined by detecting the height of water in the cylinder through the liquid level sensor. The liquid level in the drum is uniform for the same weight level of laundry. The water absorption capacity of the washings is different, so that the total water inflow is different at the same liquid level. When the liquid level is reached for the first time, the laundry may not fully absorb water, so that the drum is required to rotate while water is fed. This process is called water replenishment. In general, the water inlet of the washing machine needs 1 minute, and if the washing machine is a small amount of washings, the water is supplemented within 10 seconds.

And counting the water inflow L, classifying according to the weighing value, and judging whether the washings are small washings or medium or many washings. Wherein the determination may be accomplished by setting a threshold, for example, greater than 5 kg of medium or large amount of laundry, and less than or equal to 5 kg of small amount of laundry. The threshold value may be set according to a specification of the washing machine, for example, a specification of 10 kg of the washing machine, the threshold value may be set to 3 kg of the washing machine, and the threshold value may be set to 1 kg of the washing machine.

For medium or large washings, it is determined whether the water intake L is less than or equal to l+k. Wherein L is the water quantity threshold, which varies with the weight of the laundry. K is a coefficient, the water inflow L is smaller than or equal to L+K, and the water absorption of the washings is considered to be little, namely the water absorption data is a small amount of water absorption, otherwise, the water absorption is more.

And judging that the water absorption is smaller than the water inlet threshold value when the weighing value is large, namely a small amount of wet washings or washings which are difficult to absorb water are judged. That is, the difficulty in dehydrating the laundry is difficult.

The washing is light in weight, absorbs more water and is easy to generate large eccentricity. It was also judged that dehydration was difficult.

For the washings which are difficult to dehydrate, the washings are judged that the dehydration is difficult to reach the original set rotating speed before drying. That is, when the primary dehydration is performed, the actual value of the primary dehydration rotating speed is not easy to reach the set value of the primary dehydration rotating speed.

And reducing a primary dehydration rotating speed set value of primary dehydration, then carrying out primary dehydration, judging whether an actual value of the primary dehydration rotating speed reaches the reduced primary dehydration rotating speed set value (namely a first dehydration threshold value), if so, proving that the washing machine operates normally, and not adjusting the time after drying and hot dehydration (after secondary dehydration) until the drying and hot dehydration is finished. If not, the time adjustment is not carried out, the set rotating speed of the drying heat dehydration (secondary dehydration) is reduced, and the operation is continued until the end or the fault is reported.

For the washings with large weighing value and more water absorption, the washings are proved to be normal in water absorption, and the difficult and easy dehydration condition is easy dehydration.

For the washings with small weighing value and little water absorption, the difficult dehydration condition is proved to be easy dehydration.

For the laundry which is easy to dehydrate, it is dehydrated once, and it is judged whether the rotational speed of dehydration before drying (primary dehydration) is less than or equal to the minimum threshold value.

If the hot dehydration exists, namely the secondary dehydration exists, the adjustment is carried out according to the rotating speed of the hot dehydration and the weighing value, and the adjustment is carried out according to the numerical value of the dehydration before drying without the hot dehydration.

If not, the subsequent drying process is continued normally, and the time is not adjusted until the operation is finished.

And (4) injection:

in general, the water inlet of the washing machine is determined by detecting the height of water in the drum through a liquid level sensor. The liquid level in the drum is uniform for the same weight level of laundry. The water absorption capacity of the washings is different, so that the total water inflow is different at the same liquid level. When the liquid level is reached for the first time, the laundry may not fully absorb water, so that the drum is required to rotate while water is fed. This process is called water replenishment. In general, the water inlet of the washing machine needs 1 minute, and if the washing machine is a small amount of washings, the water is supplemented within 10 seconds.

And (5) injection:

many washing machines in the market are provided with flow meters, and the water inflow can be directly read. Or the water inflow can be judged by weight detection or other means (various), and the excessive description is omitted here.

And (6) injection:

l is a threshold value, and L varies with the weight of the laundry. It is recommended to use pure cotton national standard/European standard load to measure the curve of 'weight of washing and water inflow', based on the curve. K is a coefficient. The water inflow is less than L+K, and the washings are considered to absorb less water.

And (7) injection:

although the flow module is used for classifying the washing which is easy to dewater theoretically, the time should not jump (adjust), if the washing is added halfway in the washing process (the weight is changed) or the feet of the washing drier are not leveled, even the whole machine is damaged, the dewatering is unsuccessful, or the preset rotating speed is not reached. The minimum threshold value is defined as that the laundry weight is determined, and the laundry can be dried within a limited time with only a minimum guaranteed dehydration speed before drying, and for a small load, the laundry is easy to dry, and for a drum washing machine, a small amount of laundry is not easy to dehydrate, so that the minimum threshold value is 400 prm-600 prm, for example, a 10kg grid force dryer, and if the subsequent flow Cheng Youre is removed, the preset thermal desorption value is 600 prm-800 prm. In the case of medium or large amounts of laundry, it is relatively easy to dehydrate itself, so that the minimum threshold value is preferably 600prm to 800prm, and in the case of subsequent flow Cheng Youre, the preset thermal desorption value is preferably 800prm to 1200prm. The minimum threshold is not a set value, and the dehydration preset value should be equal to or greater than the minimum threshold.

And 8:

the weight of the washings is light, and the water absorption is not too much, which means that large eccentricity is not easy to generate, dehydration is easy to occur, dehydration before drying and thermal dehydration are easy to reach the preset rotating speed. That is, the initial moisture content of the dried laundry is determined. Since the dehumidification efficiency is fixed, the total consumption can be estimated immediately after the start of washing, and the display time is naturally adjusted only once.

Remark 9:

the two conditions are judged that the preset rotating speed is not easy to reach when the clothes are dehydrated, and firstly, the clothes are light in weight value, but the clothes absorb more water, such as cotton infant clothes. The second type is that the laundry has a large weighing value, but has little water absorption, and at this time, two possibilities are that the material of the laundry does not absorb water, or the material of the laundry has little water absorption, such as rubber material or quick-drying type laundry and toys. Shoes, etc. Another type of situation is that the laundry placed in the washer-dryer is itself wet laundry. In addition to being a wet laundry, the other conditions affect the dewatering speed because of the large eccentricity itself during dewatering.

Remarks 10:

the set point for the pre-bake spin-drying is reduced and the value is the same as the minimum threshold value inside note 7. The reason is the same. Namely a small amount of washings, the preset rotating speed is 400 prm-600 prm, and the number of washings is 600 prm-800 prm.

Remark 11:

if the set value of the dewatering rotation speed after the dewatering rotation speed is reduced is reached, the operation is continued. If the drying and hot dehydration exists, the time adjustment is not performed, the dehydration preset rotating speed of the drying and hot dehydration is maintained, and the reduction is not performed. Although this may result in the drying ending early, i.e., the laundry has been dried, the process is automatically stopped. When the display is stopped, the time on the display panel is not counted down.

Remarks 12:

if the reduced rotating speed is not reached, time jump is not carried out, and the detected washings are eccentric and are large enough to be dehydrated or can only be dehydrated at an extremely low rotating speed. Very few cases occur. Typically a piece of washware knots, a wash-baked toy, or a malfunction of the machine.

Remark 13:

classification is based on the weight after weighing. The first adjustment time is displayed at this time. From the start of the start-up procedure, a total of 1.5 to 3 minutes is taken to display the adjustment time. The middle part is provided with the following processes of water draining, weighing, water inlet and water supplementing. Generally, according to manufacturers, the water is drained for 0.1 to 1 minute, the weight is measured for 3 to 1 minute, the water is fed for about 1 minute, the water supplementing time and the times are too large according to the manufacturer, the grid force mode is adopted, the amount of the washed objects is about 1 minute, the amount of the washed objects is more, and the amount of the washed objects is about 1 to 2 minutes.

The embodiment of the application also provides a drying system, as shown in fig. 3-5, by applying the method for preventing the time jump of the washing treatment process, the system comprises an inner cylinder 2, an outer cylinder 1 and a drying air channel formed between the inner cylinder 2 and the outer cylinder 1, wherein the drying air channel comprises a first condensation air channel 3 and a second condensation air channel 4;

the first condensation air duct 3 is formed at one side of the outer cylinder 1 far away from the inner cylinder 2;

the second condensation duct 4 is formed between the outer cylinder 1 and the inner cylinder 2.

Specifically, in one embodiment, the drying air duct includes a first condensation air duct 3, a second condensation air duct 4, and a fan air duct 5;

the first condensation air duct 3 is formed on one side of the outer cylinder 1 far away from the inner cylinder 2, and the first condensation air duct 3 comprises a first air inlet 31 and a first air outlet;

the second condensation air duct 4 is formed between the outer cylinder 1 and the inner cylinder 2, the second condensation air duct 4 is provided with a second air outlet 41, and the second air outlet 41 communicates the second condensation air duct 4 with the first condensation air duct 3;

the first air inlet 31 and the second air outlet are arranged along different heights of the rear barrel bottom of the outer barrel 1, wherein the first air inlet 31 is arranged at the lower part of the rear barrel bottom of the outer barrel 1, and the second air outlet 41 is arranged at the upper part of the rear barrel bottom of the outer barrel 1; the first air outlet is positioned on the side wall of the first condensation air duct 3 and between the first air inlet 31 and the second air outlet 41;

The first air outlet is connected with the inlet of the fan duct 5. The first condensation air duct 3 and the second condensation air duct 4 are both used for circulating condensed water, and condensing the drying air flow so as to reduce the humidity of the drying air flow. A heating device is arranged in the fan air duct 5 or the drying system and is used for heating the drying air flow. The heated drying air flow firstly enters the inner cylinder 2, and after contacting with clothes, the clothes are dried, and moisture carried in the clothes enters the outer cylinder 1. Since the second condensation duct 4 is formed between the outer tube 1 and the inner tube 2, the communication position between the inner tube 2 and the outer tube 1 can be regarded as an air inlet of the second condensation duct 4. Because different clothes treatment equipment have different structures, a plurality of through holes are formed in some inner cylinders 2, and drying air flow in the inner cylinders 2 can pass through the through holes to enter the outer cylinders 1 (namely enter the second condensation air duct 4); some clothes treating apparatuses have an inner drum 2 with no through hole, but the inner drum 2 is connected to the outer drum 1, and the drying air flow in the inner drum 2 enters the outer drum 1 through the connection. That is, the present embodiment does not limit the shape and position of the air inlets of the second condensing duct 4, nor does the number of air inlets of the second condensing duct 4.

Specifically, in an embodiment, the second condensation duct 4 refers to a space between the rear bottom of the inner cylinder 2 and the rear bottom of the outer cylinder 1, and condensed water flows downward along the inner sidewall of the rear bottom of the outer cylinder 1, and contacts with the drying air flow in the second condensation duct 4 to realize condensation.

After the drying air flow enters the outer tub 1, as shown in fig. 4, a part of the drying air flow flows upward along the second condensation duct 4, and finally is discharged from the second air outlet 41; the other part of the drying air flow enters the first air inlet 31, passes through the first air inlet 31 and enters the first condensation duct 3. As shown in fig. 5, the drying air flow in the first condensation duct 3 flows upward along the duct wall of the first condensation duct 3, reaches the first air outlet, and enters the fan duct 5 through the first air outlet. Meanwhile, the drying air flow discharged from the second air outlet 41 enters the upper portion of the second condensation duct 4, and enters the fan duct 5 through the first air outlet. The drying air flow in the fan duct 5 enters the inner cylinder 2 again after being heated, and dries the clothes, so that the clothes circularly flow.
