When the washing machine is used for washing clothes, if the adding amount of the detergent is not reasonable, such as the adding amount of the detergent is too large or high-foam detergent is added, a large amount of foam can be generated in the inner barrel. The following problems occur due to the generation of a large amount of bubbles during the washing process:
(1) after the clothes are washed, the foam remains on the clothes, so that the clothes cannot be washed cleanly, and the body health of a user is influenced by wearing the clothes with the residual foam;
(2) the inner barrel of the washing machine also has residual foam, is not easy to wash away, and can emit peculiar smell after being placed for a period of time.
(3) Too much foam can increase the resistance of the clothes to rotate in the inner drum, and waste electricity resources.
(4) If the foam overflows, it can cause parts to fail or break down, leading to malfunction of the washing apparatus. Furthermore, the foam overflows and flows to the ground, which may cause the user to fall down and affect the personal safety of the user, and the foam overflows into the circuit of the whole machine, which causes the failure of the electric device or the computer board, and causes serious safety accidents such as short circuit and fire hazard.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example one
Referring to fig. 1, the embodiment provides a method for detecting and removing bubbles, which is mainly used for detecting and removing bubbles in a washing process of a washing machine. When the drum washing machine is adopted for washing clothes, the method comprises three procedures: a washing process, a rinsing process and a dehydrating process, wherein the rinsing process may be performed not less than once during the washing process, and the present embodiment is described by taking the case of performing the rinsing process once as an example. Specifically, the washing procedure includes a water injection procedure, a washing procedure, a water discharge procedure, and a dehydration procedure, the rinsing procedure includes a water injection procedure, a rinsing procedure, and a water discharge procedure, and the dehydration procedure includes a dehydration procedure. If the washing process includes not less than one rinsing process, after each rinsing process is finished, the dewatering process is firstly carried out, and then the next rinsing process is carried out. The detection and removal of the bubbles in this example are mainly focused on the washing process, the rinsing process and the dehydrating process.
Because the washing and rinsing processes are influenced by the load and the amount of washing water, and the fluctuation amplitude of the water level is large in the rotating process of the inner cylinder, the current in the motor for driving the inner cylinder to rotate is changed frequently, so that the current in the motor for driving the inner cylinder to rotate is not suitable to be used as a mode for detecting foam, and the foam in the inner cylinder is detected through the foam sensor in the washing and rinsing processes.
Because the rotating speed of the inner cylinder is high in the dehydration process, the foam can be thrown to any position in the inner cylinder, a foam sensor is not suitable for detecting the foam in the inner cylinder, the water level and the washing water volume are less influenced by the load and the washing water volume, and the rotating speed of the motor is changed according to the dehydration curve in the dehydration process, so that the power of the motor during working corresponds to a corresponding power curve. When the foam in the inner barrel is too much in the dehydration process, the resistance of the rotation of the motor is increased, the current in the motor is increased and the corresponding motor power is also increased at the same time in the normal dehydration process, so that the current of the motor for driving the rotation of the inner barrel in the dehydration process can be detected in real time, and whether the detected foam is detected or not is judged according to the motor power corresponding to the detected current.
And aiming at different clothes washing processes, the corresponding foam detection and elimination method is adopted, so that the accuracy of foam detection and the effect of foam elimination are improved.
The embodiment takes a drum washing machine as an execution body, and specifically describes methods for detecting and removing bubbles in a washing process, a rinsing process and a dehydrating process, respectively.
Fig. 2 is a flowchart of a method for detecting and removing foam during a washing process, and the method for detecting and removing foam during a washing process is described in detail below, and specifically includes the following steps:
s100, in the washing process, detecting foam in the inner cylinder through the foam sensor, and judging whether the foam sensor detects the foam in the inner cylinder.
The foam sensor comprises two identical electrodes connected by one wire. When the two electrodes of the foam sensor are short-circuited, the fact that foam is filled between the two electrodes is indicated, namely the foam is used as a conductive medium to communicate the two electrodes, the foam sensor generates a voltage signal and sends the voltage signal to the control unit, and the control unit determines that the foam sensor detects the foam according to the voltage signal, so that the condition that the content of the foam in the inner cylinder is too much can be understood. In this embodiment, the bubble sensor is mounted on the outer tub of the drum washing machine.
S101, if the foam sensor does not detect foam, continuing to execute the current washing process; and if the foam sensor detects foam, judging whether a heating function is started in the washing process.
The drum washing machine according to the embodiment has a heating function, and generally heats the washing water during the washing process in order to improve the cleaning effect of the detergent at a relatively low temperature.
S102, if the heating function is started in the washing process, continuing to execute the current washing process; if the heating function is not started in the washing process, the forced drainage time T1 and the forced water replenishing time T2 are carried out on the inner barrel.
Because the foam is eliminated by adopting the forced drainage and the forced water supplement, the water temperature of the washing water can be reduced by the forced drainage and the forced water supplement, the washing effect is influenced, and a large amount of electric resources can be wasted by continuous heating. Therefore, in the washing process in which the heating function is turned on, no defoaming treatment is performed regardless of whether the foam sensor detects foam.
In the present embodiment, the forced drainage time T1=30 seconds, and the drain valve is always opened during the forced drainage, and the drain pump is turned on and off for 5 seconds at a time sequence of 10 seconds. After the forced drainage time T1 is completed, a forced drainage process is completed. During the forced drainage process, the motor stops rotating. In the forced drainage process, as the motor stops rotating, the foam content in the inner cylinder is correspondingly reduced along with the continuous drainage of the washing water.
After the forced drainage time T1 is finished, the motor operates M circles, specifically 2 circles to 5 circles according to the normal rotation-stop ratio, and the forced water replenishing time T2 is carried out after the motor operates M circles, specifically 2 circles to 5 circles. And after one forced drainage is finished, recording the time for restoring the washing water level in the inner barrel to the preset washing water level corresponding to the current load as forced water replenishing time T2, and finishing the forced water replenishing process after the forced water replenishing time T2 is finished. In the forced water supplementing process, the motor stops rotating, water is supplemented into the inner barrel through the spraying device and the water inlet device, and in the forced water supplementing process, the foam content in the inner barrel is reduced along with the injection of washing water.
S103, judging whether the foam sensor detects foam.
After forced drainage and forced water supplement, the content of the foam in the inner cylinder is reduced, and the foam in the inner cylinder needs to be detected again at the moment.
S104, if the foam sensor does not detect foam, continuing to execute the current washing process; and if the foam sensor detects foam, forcibly draining the inner cylinder for a time T1 and forcibly replenishing water for a time T2.
S105, judging whether the forced water replenishing time N1 is larger than a first preset time N1, if N1 is smaller than or equal to N1, continuing to forcibly drain the inner cylinder for time T1 and forcibly replenish water for time T2 until the foam sensor cannot detect foam; if N1 > N1, the current washing course is continuously performed.
Through multiple tests, the first preset number of times N1=5 in the embodiment eliminates the foam in the inner cylinder through repeated forced drainage and forced water supplement. If the foam is still excessive after 5 times of forced drainage and forced water supplement, in order to save resources, the foam in the inner barrel is not eliminated in the current washing process, and the foam can be continuously detected and eliminated in other washing processes after the washing process.
In order to avoid the laundry from being washed unclean, the forced draining time T1 and the forced water replenishing time T2 of the present embodiment do not occupy the total time of the washing process, i.e., the time from the beginning to the end of the washing process is prolonged.
Through carrying out foam detection and elimination in the washing process, the problems of foam overflow, foam residue and the like caused by a large amount of foam generated in the washing process are solved, and the cleaning capability of washing clothes is improved.
Fig. 3 is a flowchart of a method for detecting and removing foam during rinsing according to this embodiment, and the method is described in detail below, and specifically includes the following steps:
s200, in the rinsing process, detecting foam in the inner barrel through the foam sensor, and judging whether the foam sensor detects the foam in the inner barrel.
S201, if the foam sensor does not detect foam, continuing to execute the current rinsing process; and if the foam sensor detects foam, forcibly draining the inner cylinder for a time T1 and forcibly replenishing water for a time T2.
S202, judging whether the foam sensor detects foam.
S203, if the foam sensor does not detect foam, continuing to execute the current rinsing process; if the foam sensor detects foam, whether the forced water replenishing time N1 is larger than a first preset time N1 or not is judged.
S204, if N1 is not more than N1, continuing to forcibly drain the inner cylinder for time T1 and forcibly replenish water for time T2 until the foam sensor cannot detect foam; if N1 > N1, the current rinsing process is continued.
The method of detecting and removing foam during rinsing is similar to the method of detecting and removing foam during washing and will not be described in detail herein.
FIG. 4 is a flow chart of a method for detecting and removing foam during dehydration, which is described in detail below and includes the following steps:
s300, in the dehydration process, detecting the current of the motor for driving the inner cylinder to rotate, and judging whether the power corresponding to the current of the motor does not exceed the preset power within the continuous T3 time.
The current detection unit detects the current of the motor during working in the dehydration process, the current detection unit exists in the motor, the detected current is sent to the control unit, and the control unit calculates the corresponding motor power according to the detected current.
S301, if the power corresponding to the current of the motor does not exceed the preset power within the continuous T3 time, continuing to execute the current dehydration process; otherwise, the water is forcibly drained for time T1 to the inner cylinder, the rotating speed of the motor is reduced to W, and then the water is forcibly replenished for time T2 to the inner cylinder.
In the process of rotating the inner cylinder, the power corresponding to the current of the motor at a certain moment exceeds the preset power, which may be caused by the presence of foam in the inner cylinder or by load or other reasons, so that it cannot be determined that there is no foam or the amount of foam in the inner cylinder is small. In the embodiment, whether the foam in the inner cylinder is excessive or not is determined and the foam is eliminated by determining whether the power corresponding to the current of the motor does not exceed the preset power within the continuous time T3.
In this embodiment, the time T3=5 seconds, the forced drainage time T1 and the forced water replenishment time T2 are consistent with the forced drainage time T1 and the forced water replenishment time T2 in the washing process, and the corresponding functions are also to eliminate the foam in the inner tub. Specifically, the forced drainage time T1=30 seconds, and the drain valve is always opened during the forced drainage, and the drain pump is turned on and off for 5 seconds at a time sequence of 10 seconds. After the forced drainage time T1 is completed, a forced drainage process is completed.
And when the water is forcibly drained, the rotating speed of the motor is slowly reduced to W. Through reducing motor speed for some foams can slowly break, play the effect of defoaming. In the embodiment, the rotating speed W is obtained through a plurality of tests, and the rotating speed W =93 revolutions per minute.
S302, detecting the current of the motor driving the inner barrel to rotate, and judging whether the power corresponding to the current of the motor in the continuous T3 time does not exceed the preset power.
S303, if the power corresponding to the current of the motor does not exceed the preset power within the continuous T3 time, continuing to execute the current dehydration process; otherwise, comparing the magnitude relation between the forced water discharging times N2 in the current dewatering process and the second preset times N2 and the third preset times N3.
S304, if N2 is less than N2, the inner cylinder continues to be forcibly drained and replenished with water until the motor power corresponding to the current measured in the continuous time T3 does not exceed the preset power;
if the N2 is not less than N2 is less than N3, the current washing process stops running for a first preset time T1And at a first preset time T1Then continuously executing the current dehydrationA process;
if N2 is N3, the current washing process stops running for a second preset time T2And at a second preset time T2Then continuing to execute the current dehydration process;
if N2 is more than N3, the current washing process stops running for a third preset time T3And at a third preset time T3Then continuing to execute the current dehydration process;
wherein T is1＜T2＜T3Time T3Which is the time from the current moment of the current washing process to the end moment of the current washing process in normal work.
In this embodiment, N2=4, N3=5, and time T1Time T of =90 seconds2For =300 seconds, the foam in the inner cylinder is first eliminated by repeated forced drainage and forced water replenishment. If the foam is still too much after 3 times of forced drainage and forced water supplement, the current dehydration process is suspended for a period of time for saving water resources, the foam automatically sinks and slowly breaks, and the foam is automatically discharged after being changed into water.
If excessive foam is still generated after 5 times of forced drainage and forced water supplement, in order to save resources, the defoaming treatment is not continued until the current dehydration process is finished.
If the current dehydration process is the dehydration process in the dehydration program, after the dehydration program is executed, the user opens the drum washing machine and finds that the clothes are not dehydrated, and the excessive detergent is put in the clothes during washing.
In order to avoid the bad dewatering effect of the clothes, in this embodiment, the forced draining time T is used in the dewatering process of the dewatering program1Time T2And time T3The time of the dehydration curve is not occupied, namely the time from the beginning to the end of the dehydration program is prolonged.
By adopting the method for detecting and eliminating the foam, the foam amount in the washing cylinder is reduced, and the problems of foam overflow, foam residue and the like caused by excessive foam are further avoided.
The embodiment also provides a washing machine which adopts the method for detecting and eliminating the foam, and when the washing machine is a roller washing machine, the foam sensor is arranged on the outer cylinder of the roller washing machine; when the inner cylinder is subjected to forced water supplement, the spraying device and the water inlet device of the drum washing machine are used for simultaneously supplementing water. The problem of foam residue that too much foam leads to is solved, improve the clean ability of wasing the clothing, avoided the interior condition that leads to appearing the peculiar smell because of the foam is remained of inner tube.
