Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.

A clothes treating apparatus and a method, device, and storage medium for removing bubbles thereof according to embodiments of the present application will be described below with reference to the accompanying drawings.

The embodiment of the application provides a method for eliminating foam of clothes treatment equipment, when a large amount of foam exists in a washing barrel, in the dehydration process, a fan is controlled to blow cold air into a drying tunnel firstly, then the cold air is blown into the washing barrel through the drying tunnel, the foam which is possibly gathered in the drying tunnel and is near a drying tunnel opening in the barrel is blown away through the cold air, the continuous gathering of the foam is avoided, a smooth air outlet channel is formed, and the cold air can promote the foam to break and further eliminate the foam. Then the heating of the heating pipe is controlled, and hot air generated by heating the heating pipe is blown into the washing barrel through the smooth drying tunnel by the fan, so that the problem that the hot air cannot be smoothly blown out due to the fact that the drying tunnel is blocked by foam is effectively avoided, and the dry burning condition of the drying tunnel is avoided. In hot-blast washtub that blows in, the foam in the washtub can disperse rapidly under hot-blast blowing, and hot-blast can accelerate the foam to break, and it is long when having shortened the elimination of foam, and the foam clearance is high, gets rid of the foam and spills over the scheduling problem in order to avoid the clothing rinsing unclean or foam, can reduce the load weight that the rotation of washtub bore simultaneously, is favorable to protecting motor and drying system, extension laundry treatment facilities's life.

In the embodiment of the application, cold air refers to air with a lower temperature or room temperature, and hot air refers to air with a higher temperature after being heated by the heating pipe.

The laundry treating apparatus may remove bubbles at various stages of a washing process by the method provided by the embodiments of the present application, such as removing bubbles during a dehydration process, removing bubbles before rinsing drainage, removing bubbles while draining, and the like. The examples of the present application illustrate the process of removing foam using the method provided in the examples of the present application at each washing stage, respectively.

First, explaining a scheme of removing bubbles during dehydration, it may be determined whether a large amount of bubbles are present in the washing tub before performing a process of removing bubbles, and if so, the bubbles may be removed by the method provided in the embodiment of the present application. If not, the defoaming procedure is not executed, but the preset dehydration procedure is directly executed. Therefore, the foam eliminating program is executed only when a large amount of foam exists in the washing barrel, the condition that the foam eliminating program is executed under the condition that the amount of the foam is less is avoided, and unnecessary resource waste is avoided.

Whether a large amount of bubbles is present is determined by detecting the water level in the washing tub in the embodiment of the present application. Specifically, a water level sensor is provided in the laundry treating apparatus, and the water level sensor may be a frequency type water level sensor, a water level frequency meter, or the like. When the clothes processing equipment determines that the rinsing program is finished and enters the dehydration stage, the current water level frequency value is detected by the water level sensor, and the water level frequency value can be a single detection value of the water level sensor, and also can be an average value, a median value or a maximum value of continuous multiple detection values of the water level sensor.

The laundry treating apparatus compares the current water level frequency value with a second preset threshold value, which may be a water level frequency value corresponding to a maximum washing water level of the laundry treating apparatus. If the current water level frequency value is less than or equal to the second preset threshold value through comparison, the current water level is determined to be lower than or equal to the maximum washing water level of the clothes treatment equipment, and a large amount of foam does not exist in the current washing barrel, so that the preset dehydration program is directly executed. If the current water level frequency value is larger than the second preset threshold value, the current water level is determined to be higher than the maximum washing water level of the clothes treatment equipment, and then a large amount of foam is determined to exist in the current washing barrel, and the foam in the washing barrel is eliminated through the method provided by the embodiment of the application.

Referring to fig. 1, the laundry treating apparatus removes bubbles by the steps including:

step 101: and controlling a fan of the drying system to be started for a first preset time, and blowing cold air into the drying tunnel.

In the embodiment of the present application, the laundry treating apparatus may be a washing machine or a laundry dryer having a drying system, or the like. The drying system comprises a drying tunnel, a heating pipe, a fan and a condenser, wherein the heating pipe and the fan are positioned in the drying tunnel, and the drying tunnel, the condenser and the washing barrel form a circulating air duct.

The embodiment of the application mainly eliminates the foam by blowing hot air into the washing barrel through the heating pipe and the fan. The uppermost film of the foam is convex upward, and the curved film is sensitive to evaporation due to the reduced properties of the surface film, and the foam will break down by itself when the film is thinned to a certain extent as the evaporation is faster at higher temperatures. At higher temperatures the foam in the washing tub breaks down starting from the top and the foam volume decreases regularly with time.

However, in the case where a large amount of foam is present in the washing tub, the foam is likely to rush into the drying tunnel and accumulate in the drying tunnel, or accumulate at the drying tunnel mouth to block the drying tunnel or the drying tunnel mouth. If the hot air is directly blown, the hot air cannot be blown out in the drying tunnel due to the blockage of the drying tunnel or the drying tunnel opening, so that the temperature in the drying tunnel is quickly raised, the drying tunnel is dried, and a drying system of the clothes treatment equipment is easy to damage.

In order to avoid the situation that the drying channel is dry-burned due to direct hot air blowing, in the embodiment of the application, firstly, cold air is blown into the drying channel through the step 101, and foams blocked in the drying channel are blown away through the cold air, so that the drying channel is smooth, and then, hot water and hot air are blown into the washing barrel through the drying channel through the operation of the step 102. Furthermore, the cold air also has the function of promoting the foam film to evaporate and further break the foam film.

Specifically, when the washing machine enters a dehydration stage and a large amount of foam is detected to exist in the current washing barrel, a fan included in the drying system is controlled to be started, and the fan is controlled to operate at a certain rotating speed for a first preset time. The fan rotates to generate cold air in the drying tunnel, the cold air blows away the foam gathered in the drying tunnel, the foam can not be gathered continuously in the drying tunnel, so that a smooth air outlet channel is formed in the drying tunnel, and part of the foam can be eliminated by blowing the cold air.

The first preset time period may be 50s, 60s, 80s, or the like. The embodiment of the application does not limit the specific value of the first preset duration, and the setting can be performed according to the requirement in practical application.

The clothes treatment equipment starts timing while controlling the fan to be started, the timing duration is compared with a first preset duration, and if the timing duration is smaller than the first preset duration, timing is continued. If the counted time period is equal to the first preset time period, the hot wind starts to be blown into the washing tub through the following operation of step 102.

In the embodiment of the present application, the operation of blowing the cold air by the blower in step 101 may be performed in the dewatering stage, or may be performed in the washing stage and/or the rinsing stage, and the cold air blows off the bubbles blocked in the drying tunnel in these stages, and simultaneously the cold air promotes the evaporation of the bubble film and breaks the bubble film, thereby eliminating a part of the bubbles in the washing tub.

Step 102: and controlling a heating pipe of the drying system to be opened according to the first preset time, and blowing hot air generated by the heating pipe into the washing barrel through the drying tunnel by the fan.

When the time length of blowing cold air by starting the fan is determined to reach a first preset time length, a heating pipe included in the drying system is controlled to be started, the temperature of air in the drying tunnel is raised by heating the heating pipe, air generated by rotation of the fan is changed into hot air with higher temperature, and the generated hot air is blown into the washing barrel through the drying tunnel by the fan.

In the step 101, cold air with a first preset duration is blown into the drying tunnel, and the foam gathered in the drying tunnel is blown away by the cold air, so that the drying tunnel is kept smooth. When hot air is blown through the step, the hot air can smoothly enter the washing barrel through the drying tunnel and cannot be retained in the drying tunnel, so that the temperature in the drying tunnel cannot be quickly raised, and the dry burning condition of the drying tunnel is avoided.

After hot air enters the washing barrel, foam in the washing barrel is contacted with the hot air, and a large amount of foam in the washing barrel can be rapidly broken from the top under the action of the temperature of the hot air and the blowing force of the wind, so that the effect of rapidly eliminating the foam in the washing barrel is realized.

Considering that when the amount of foam in the barrel is large, a large amount of foam may be blocked at the drying tunnel outlet, and if cold air is blown directly through the step 101, it is difficult to remove the foam at the drying tunnel outlet, although the foam in the drying tunnel is blown away through the operation of the step 101, a large amount of foam outside the drying tunnel outlet can cause the subsequently blown hot air to be retained at the drying tunnel outlet in a short time. Based on this, other embodiments of the present application eliminate the foam accumulated at the exit of the drying tunnel by spraying before performing step 101. As shown in fig. 2, the method specifically includes:

s1: and controlling the condensation valve and the spray valve to be opened for a second preset time, and spraying water to the washing barrel and the condenser.

When the washing machine enters a dehydration stage and detects that a large amount of foam exists in the current washing barrel, the condenser valve of the condenser is controlled to be opened, water is fed, the spray valve is controlled to be opened, water is sprayed into the washing barrel and onto the condenser, the foam in the washing barrel and at the condenser is washed through the spray water, the purpose of eliminating the foam blocked at the outlet of the drying tunnel is achieved, and the outlet of the drying tunnel is ensured to be smooth.

And controlling the opening of the condensing valve and the spraying valve and starting timing at the same time, and comparing the timing duration with a second preset duration. And if the timed duration is less than the second preset duration, continuing spraying water. If the counted time period is equal to the second preset time period, the following step S2 is executed.

The second preset time period may be 10s or 15s, and the like, and the value of the second preset time period is not limited in the embodiment of the application, and may be set according to a requirement in practical application.

S2: and controlling the condensation valve and the spray valve to be closed and controlling the drain valve to be opened for a third preset time period according to the second preset time period.

And when the duration of the spray water reaches a second preset duration, controlling the condensation valve and the spray valve to be closed, and stopping spraying the water. And controlling the drain valve to be opened for a third preset time period to drain part of water in the washing tub, so as to avoid foam or water overflow caused by overhigh water level in the washing tub due to the water spray in the step S1.

The third preset time period may be 10s or 15s, and the like, and the value of the third preset time period is not limited in the embodiment of the application, and may be set according to a requirement in practical application.

And controlling the opening of the drain valve and starting timing at the same time, and comparing the timing duration with a third preset duration. And if the timed duration is less than the third preset duration, continuing draining. If the counted time period is equal to the third preset time period, the following step S3 is executed.

S3: and controlling the drainage valve to be closed according to the third preset time, and adding one to the first cycle time.

And controlling the drainage valve to be closed when the drainage time reaches a third preset time, and adding one to the first cycle number corresponding to the combined program of the spraying step and the drainage step.

S4: and judging whether the first cycle number after the addition reaches a first preset number, if so, executing the operation of the step 101, and if not, executing the step 1.

And comparing the first cycle number after the addition with a first preset number, and returning to the step of 1 to continue the cycle execution if the first cycle number is less than the first preset number. And if the first cycle number is equal to the first preset number, jumping out of the cycle of the spraying step and the water drainage step, and subsequently executing the operation of blowing cold air in the step 101.

In this way, the spraying step and the draining step are executed, and when it is determined that the draining time period of the draining step reaches the third preset time period, the operation of the step S1 is executed in a loop again until the first loop frequency reaches the first preset frequency, and the operation of the step S101 is executed. The first preset number of times may be 3 or 4, etc. The value of the first preset times is not limited, and the value can be set according to requirements in practical application.

The spraying step and the water draining step are executed in a circulating mode, foam in the washing barrel is washed, partial foam can be eliminated, the height of the foam accumulated in the washing barrel is lowered, the foam accumulated at the outlet of the drying tunnel is reduced, and the outlet of the drying tunnel is smooth. And then blowing the blocked foam in the drying tunnel into the washing barrel through the smooth drying tunnel outlet by the cold air blowing operation of the step 101, and further blowing the foam at the drying tunnel outlet so as to keep the inside of the drying tunnel and the outlet of the drying tunnel smooth. Therefore, hot air can be smoothly blown into the washing tub in the subsequent step 102 of blowing hot air, so that the hot air is not retained in the drying tunnel, and the dry burning of the drying tunnel is avoided.

In other embodiments of the present application, after the heating pipe is controlled to be opened in step 102, and hot air is blown into the washing tub, in order to further increase the foam removing speed, a manner of removing foam, such as spraying, rotating the tub at a low speed, standing, or the like, is also implemented in an auxiliary manner. As shown in fig. 3, after the step 102 is executed, the execution starts from the step S5, and specifically includes:

s5: and controlling the opening of the spray valve for a fourth preset time period to spray water into the washing barrel.

And after the heating pipe is controlled to be opened, the spray valve is controlled to be opened for a fourth preset time period, and water is sprayed into the washing barrel. The fourth preset time period may be 10s or 15s, and the like, and the value of the fourth preset time period is not limited in the embodiment of the application, and may be set according to a requirement in practical application.

The foam in the washing tub is washed by the shower water, and a part of the foam can be eliminated. The fan and the heating pipe are always opened in the process of spraying water, namely, hot air is continuously blown into the washing barrel in the process of spraying water. By adopting two foam eliminating modes of spraying water and blowing hot air, the foam in the washing barrel can be quickly broken, and the foam eliminating speed is improved.

And controlling the spray valve to start timing while opening, and comparing the timing duration with a fourth preset duration. And if the timing duration is less than the fourth preset duration, continuing spraying water. If the counted time period is equal to the fourth preset time period, the following step S6 is executed.

And when the duration of the spray water reaches the fourth preset duration, controlling the spray valve to close and stopping spraying the water. And controlling the drain valve to be opened for a fifth preset time period to drain part of water in the washing tub, so as to avoid foam or water overflow caused by overhigh water level in the washing tub due to the water spray in the step S5.

And controlling the opening of the drain valve and starting timing at the same time, and comparing the timing duration with a fifth preset duration. And if the timed duration is less than the fifth preset duration, continuing draining. If the counted time period is equal to the fifth preset time period, the following step S7 is executed.

S7: and controlling the drain valve to be closed according to the fifth preset time, and driving the washing barrel to rotate for a sixth preset time at a preset rotating speed.

And when the drainage time reaches a fifth preset time, controlling the drainage valve to close and stopping drainage. And then the washing tub is driven to rotate at a preset rotation speed for a sixth preset time period by the motor. The preset rotating speed can be a lower rotating speed, such as 40r/min or 45 r/min. The sixth preset time period may be 5s or 8s, etc. The specific values of the preset rotating speed and the sixth preset time are not limited in the embodiment of the application, and can be set according to requirements in practical application.

The washing barrel is driven to rotate through the preset rotating speed, the load can rotate along with the washing barrel, and the foam coated inside the load is turned to the surface, so that the foam is contacted with hot air and eliminated, and the foam elimination rate is improved. And the low-rotating-speed rotating barrel can also promote the flow of the washing water in the barrel, so that the washing water impacts the foam to promote the foam to break.

And starting timing while driving the washing barrel to rotate, and comparing the timing duration with a sixth preset duration. If the timed duration is less than the sixth preset duration, the washing barrel is continuously driven to rotate. If the counted time period is equal to the sixth preset time period, the following step S8 is executed.

S8: and controlling the washing barrel to stop rotating according to the sixth preset time, and adding one to the second cycle times corresponding to the combined program of the spraying step, the water draining step and the washing barrel rotating step.

The mode of blowing hot air and spraying water is combined in the mode to accelerate the foam eliminating speed, and the washing barrel is driven to rotate when only the mode of blowing hot air is adopted, so that the foam coated inside the load is eliminated, and the foam eliminating efficiency is improved.

In the process of the above steps S5-S10, a mode of eliminating foam by standing can be added. As shown in fig. 4, the following step S8' is executed after step S7, including:

s8': and controlling the washing tub to stop rotating according to the sixth preset time period, keeping still for the seventh preset time period, adding one to the second cycle number, and then performing step S9.

That is, when it is determined that the rotation time period of the washing tub reaches the sixth preset time period, the washing tub is controlled to stop rotating and to remain stationary for the seventh preset time period. The seventh preset time period may be 35s or 40s, and the like, and the value of the seventh preset time period is not limited in the embodiment of the application, and may be set according to a requirement in practical application.

In the standing process, hot air is continuously blown into the washing barrel, two foam eliminating modes of hot air blowing and standing are combined, the foam eliminating speed is increased, and the foam eliminating efficiency is improved.

In the above embodiments, the amount of the foam remaining in the washing tub after the various ways of removing the foam are adopted is small, so that the heating pipe and the blower can be turned off in the subsequent process of executing the preset dehydration procedure, so as to save electric energy. Or, the heating pipe can be kept open, and the residual foam in the washing barrel is further eliminated through hot air.

S13: and adding one to the third cycle number, judging whether the third cycle number reaches a third preset number or not, if so, executing the step S12, and if not, returning to the step S5.

Specifically, a variation parameter of the water level frequency is acquired. The variation parameter may be a difference between a value of the water level frequency before the foam is removed and a value of the water level frequency after the preset dehydration process is performed. The obtaining method of the water level frequency value after the preset dehydration procedure is executed is the same as the obtaining method of the water level frequency value before the foam is eliminated, and the details are not repeated herein. And after the change parameter of the water level frequency is acquired, comparing the change parameter with a first preset threshold, if the change parameter is greater than or equal to the first preset threshold, determining that the difference between the foam elimination and the water level in the washing barrel before and after dehydration is large, effectively eliminating the foam in the washing barrel, and controlling the fan and the heating pipe to be closed to continue to execute the subsequent washing program if the dehydration is successful.

If the variation parameter is smaller than the first preset threshold value, the foam elimination and the difference of the water levels in the washing barrel before and after dehydration are determined to be not large, and the fact that more foams still exist in the washing barrel after the dehydration is indicated. Therefore, the loop execution is started again from the operation of step S5, until the third loop time of the loop execution again reaches the third preset time and the variation parameter corresponding to each loop is smaller than the first preset threshold, or, although the third loop time does not reach the third preset time, it is detected that the variation parameter is greater than or equal to the first preset threshold, the fan and the heating pipe are controlled to be closed, and the subsequent washing program is continuously executed.

In other embodiments of the present application, as shown in fig. 6, after the dehydration stage, the water may be drained, the cold air may be blown, and the dehydration process may be performed, and if the detected foam amount is small during the dehydration process, the cold air blowing may be stopped, and the dehydration process may be ended. If a significant amount of foam is detected, the foam is eliminated by a combination of means. Specifically, the foam is eliminated through the following steps of:

a1: and controlling the drain valve to be opened for an eighth preset time, and controlling the drain valve to be closed when the drainage time reaches the eighth preset time.

A2: and controlling a fan of the drying system to be started, and blowing cold air into the drying tunnel.

Before drainage, or in the process of drainage, or after the drainage valve is closed, a fan of the drying system is controlled to be started, cold air is blown into the drying tunnel, the cold air blows off foam gathered in the drying tunnel, the foam cannot be gathered continuously in the drying tunnel, a smooth air outlet channel is formed in the drying tunnel, and the cold air blowing can accelerate the evaporation of the foam film to break. And in the drainage process, cold air blowing can also promote the foam to be discharged along with water flow, so that the foam amount in the washing barrel is reduced. In fig. 6, the fan is turned on after the drain valve is closed, and in practical application, the fan may be turned on before or during the draining process.

A3: and executing a preset dehydration program.

After the drain valve is closed, the fan blows cold air, and meanwhile, a preset dehydration program can be executed, and the preset dehydration program can be a preset dehydration program in the dehydration stage. Blowing cold air can accelerate the evaporation of the foam film and promote the foam to break. And the bubbles may also be broken by colliding with the load or the tub wall during the rotation of the washing tub during the execution of the predetermined dehydration process.

A4: and judging whether the current foam amount is larger than a set threshold value, if so, executing the step A6, and if not, executing the step A5.

In the process of executing the preset dehydration program, the current water level frequency value is detected by the water level sensor, and the current water level frequency value is compared with a third preset threshold value, where the third preset threshold value may be the water level frequency value after the dehydration of the laundry treatment apparatus is completed under the condition of less foam amount. If the current water level frequency value is less than or equal to the third preset threshold value, it is determined that the current amount of foam in the washing tub is small, and step a5 is performed subsequently. If the current water level frequency value is greater than the third preset threshold value, it is determined that a large amount of foam exists in the current washing tub, and step a6 is executed.

A5: and controlling the fan to be closed, and controlling the preset dehydration program to be finished.

And B, after the current water level frequency value is detected to be lower than a third preset threshold value through the step A4, determining that the foam amount is less and the dehydration is finished, controlling the fan to be closed at the moment, and ending the dehydration program.

A6: and executing a fourth preset number of preset spraying defoaming program.

After detecting that the current water level frequency value is greater than the third preset threshold value through step a4, executing a preset spraying defoaming program. The preset spray defoaming procedure is similar to the operations of steps S1-S4 in the above embodiment. Specifically, the condensing valve and the spray valve are controlled to be opened for a second preset time period, and water is sprayed to the washing barrel and the condenser. And controlling the condensation valve and the spray valve to be closed and controlling the drain valve to be opened for a third preset time period according to the second preset time period. And controlling the drain valve to be closed according to the third preset time, and adding one to the cycle number. And judging whether the number of the added cycles reaches a fourth preset number, and if so, executing the operation of the step A7. And if not, returning to the operation of controlling the opening of the condensing valve and the spraying valve for a second preset time, and executing the step A7 in a circulating manner until the circulating times reach a fourth preset time.

And circularly executing the spraying step and the water drainage step, flushing the foam in the washing barrel, eliminating partial foam, and lowering the height of the foam accumulation in the washing barrel so as to reduce the foam accumulation at the outlet of the drying tunnel and ensure that the outlet of the drying tunnel is smooth. And in the process, the fan continuously blows cold air, the blocked foam in the drying tunnel is blown into the washing barrel through the smooth drying tunnel outlet, and the foam at the drying tunnel outlet is further blown away, so that the inside of the drying tunnel and the outlet of the drying tunnel are kept smooth.

A7: and controlling a heating pipe of the drying system to be opened according to the fourth preset times when the execution times of the preset spraying defoaming program reach the fourth preset times, and blowing hot air generated by the heating pipe into the washing barrel through the drying tunnel by the fan.

The drying tunnel and the drying tunnel outlet are kept smooth, and hot air can be smoothly blown into the washing barrel when the heating pipe is opened to blow hot air, so that the hot air cannot be retained in the drying tunnel, and the drying tunnel is prevented from being dried. And hot air is blown into the washing barrel, so that the foam breaking in the barrel can be accelerated, and the defoaming speed is improved.

After blowing hot air into the washing tub, in order to further increase the foam removal rate, a method of removing foam, such as spraying, low-speed tub rotation, and standing, is also assisted. The subsequent execution is the same as the operations of steps S5-S13 in FIG. 5, and will not be described herein.

In the embodiment shown in fig. 6, after the dehydration stage, the water is drained and dehydrated, and cold air is blown to remove a part of the foam and promote the foam to be discharged along with the water flow. And then judging whether the foam amount in the barrel exceeds a threshold value, and if so, quickly eliminating the foam through various foam eliminating modes such as cold air blowing, hot air blowing, spraying, low-speed barrel rotating, standing and the like. If not, the fan is closed, the current dehydration program is ended, the defoaming program does not need to be executed, and electric energy is saved.

The program for removing foam provided in any of the embodiments described above may be applied not only to the dewatering process, but also to various stages of the washing process, for example, to the rinsing stage, and the foam amount is detected in the rinsing process, and when the foam amount exceeds a set threshold, the foam is removed by one or more foam removing methods such as cold air blowing, hot air blowing, spraying, low-speed barrel rotation, and standing.
