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.

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 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:

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.

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 the circulation execution is started again from the operation of step S5 until the second circulation number reaches the second preset number, and the preset dehydration process is executed through step S10.
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.
And controlling the washing barrel to stop rotating and start timing at the same time, and comparing the timing duration with a seventh preset duration.

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.
