Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 is a schematic flow chart of a foam eliminating method for a washing machine according to an embodiment of the present disclosure. The method is suitable for application scenes in which foam between the inner cylinder and the outer cylinder of the washing machine needs to be eliminated. The method may be performed by a washing machine suds elimination apparatus provided by embodiments of the present disclosure, which may be implemented in software and/or hardware. As shown in fig. 1, the method comprises the steps of:
s101, after the washing machine enters a dewatering procedure, acquiring the foam amount in the washing machine.
Specifically, excessive foam is generated in the washing process due to excessive amount of detergent input in the washing process, and the foam is thrown out of the inner cylinder under the action of centrifugal force and enters the middle of the inner cylinder and the outer cylinder to form the foam between the inner cylinder and the outer cylinder of the washing machine. The washing machine enters a dewatering process, for example, the washing machine performs a draining and dewatering operation to drain the washing waste water in the drum and on the laundry after the main washing process is finished and before rinsing. If the foam between the inner cylinder and the outer cylinder of the washing machine is excessive in the process, the resistance of the inner cylinder and the outer cylinder of the washing machine is increased during dehydration, so that the motor is overloaded during dehydration and cannot dehydrate, and therefore, the foam between the inner cylinder and the outer cylinder of the washing machine is obtained after the washing machine enters a dehydration procedure.
In some embodiments, obtaining an amount of foam within a washing machine includes:
acquiring the state of a dehydration motor in the washing machine to acquire the foam amount;
and when judging that the resistance of the dewatering motor exceeds a preset value and/or is overloaded, judging that the foam quantity exceeds the preset foam quantity threshold value.
Specifically, when the resistance of the dewatering motor exceeds a preset value and/or is overloaded, namely the dewatering motor cannot dewater, the foam amount is judged to exceed a preset foam amount threshold value. If the foam between the inner cylinder and the outer cylinder of the washing machine is excessive, the resistance of the inner cylinder and the outer cylinder of the washing machine is increased during dehydration, so that the motor is overloaded during dehydration and cannot be dehydrated, and therefore, whether the foam between the inner cylinder and the outer cylinder of the washing machine is excessive or not can be judged according to the state of the dehydration motor in the washing machine, namely, whether the foam exceeds a preset foam threshold value or not is judged. For example, after the washing machine enters a dehydration procedure, if the dehydration motor cannot dehydrate, judging that the foam between the inner cylinder and the outer cylinder of the washing machine is excessive, namely that the foam between the inner cylinder and the outer cylinder of the washing machine exceeds a preset foam threshold; if the dehydration motor can normally dehydrate, the foam between the inner cylinder and the outer cylinder of the washing machine can be judged not to be excessive. Therefore, by acquiring the state of the dewatering motor in the washing machine, whether the foam amount between the inner cylinder and the outer cylinder of the washing machine exceeds a preset foam amount threshold value can be judged, and a foam detection device is not required to be additionally arranged in the washing machine, so that the manufacturing cost of the washing machine is saved.
S102, if the foam quantity exceeds the preset foam quantity threshold value, controlling a drainage pump of the washing machine to be closed, suspending or stopping a dewatering process, and controlling water entering the washing machine until the water level in the washing machine is over the heater at the bottom of the outer barrel of the washing machine.
The preset foam amount threshold is set according to specific actual requirements, and the embodiment of the disclosure is not limited in particular. Specifically, when the foam amount in the washing machine obtained based on S101 exceeds the preset foam amount threshold, it may be determined that the foam is excessive, which may cause an increase in resistance of the inner and outer cylinders of the washing machine during dehydration, overload dehydration of the motor, and impossible dehydration, and at this time, a foam elimination procedure, that is, elimination of foam between the inner and outer cylinders of the washing machine, is required. Further, the draining pump of the washing machine is turned off, the dewatering process of the washing machine is suspended or terminated, the defoaming process is started, the water inlet process of the washing machine is turned on, and water is fed into the washing machine until the water level L in the washing machine is lower than the heater at the bottom of the outer cylinder of the washing machine.
It should be noted that, in the above embodiment, the dewatering process of the washing machine is suspended or terminated, the defoaming process is started, the dewatering process and the defoaming process may be two different execution processes, or the defoaming step may be added when the foam amount is determined to exceed the preset foam amount threshold value during the execution of the dewatering process, and the dewatering step is suspended or terminated, where the defoaming step and the dewatering step are steps in the dewatering process.
Specifically, the heater can be installed between the inner barrel and the outer barrel of the washing machine, the height of the heater can be higher than the bottom of the outer barrel and lower than the bottom of the inner barrel, water is fed into the washing machine until the water level in the washing machine is lower than that of the bottom of the outer barrel of the washing machine, and the heating pipe can be effectively prevented from being damaged due to dry heating when the heater is opened. Preferably, the water inlet level into the washing machine is higher than the heater and lower than the bottom of the inner cylinder, so that the heating time of the heater can be saved. In addition, the inflow in the process of executing the foam elimination program can be stored in the controller in the washing machine in advance, real-time water level monitoring is not needed, and the cost of the washing machine for eliminating the foam is reduced.
S103, controlling the heater to heat so as to eliminate foam in the washing machine.
Specifically, in S102, after water is fed into the washing machine until the water level L in the washing machine is lower than the heater at the bottom of the outer tub of the washing machine, the heater is turned on to heat so as to eliminate foam in the washing machine, so that the foam amount is lower than a preset foam amount threshold value, and normal dehydration of the washing machine is realized.
In some embodiments, controlling the heater to heat includes:
controlling the heater to heat until the water temperature in the washing machine exceeds a first preset temperature value;
and controlling the heater to be turned off after the duration that the water temperature in the washing machine exceeds the first preset temperature value exceeds a preset time threshold.
Specifically, when the washing machine cannot dewater normally due to excessive foam quantity between the inner cylinder and the outer cylinder of the washing machine, the heater needs to be controlled to heat so as to eliminate foam. The first preset temperature value may for example be 50 ℃, preferably 100 ℃. For example, after the heater heats the water to boil, the water can be continuously heated to generate hot water and steam in the washing machine barrel, so that the air temperature in the washing machine barrel is increased, foam between the inner barrel and the outer barrel of the washing machine is heated, and further the foam between the inner barrel and the outer barrel of the washing machine is eliminated; when the water temperature in the washing machine exceeds the first preset temperature value, the heater is automatically turned off after the time exceeds the preset time threshold, so that unnecessary waste caused by too long heating time is avoided. For example, in order to improve the heating efficiency of the heater, the heater may be set to operate at a maximum constant power for heating.
The preset time threshold may be set according to specific actual requirements, so that it is ensured that the foam can be eliminated within the preset time threshold and the foam amount is lower than the preset foam amount threshold.
Therefore, after the washing machine enters the dewatering program, firstly the foam amount in the washing machine is obtained, whether the foam amount exceeds the preset foam amount threshold is judged based on the foam amount in the washing machine, if the foam amount exceeds the preset foam amount threshold, further, the drainage pump of the washing machine is closed, the dewatering program is suspended or terminated, the water inlet program is started, the washing machine is fed to the water level of the washing machine, which is beyond the heater at the bottom of the outer cylinder of the washing machine, further, the heater is started for heating, hot water is generated through the heating pipe, steam is generated, the temperature of the inner cylinder and the outer cylinder of the washing machine is increased, the foam amount between the inner cylinder and the outer cylinder of the washing machine can be quickly eliminated by utilizing the steam generated by the water during heating, and the water is heated through the inner heater of the washing machine, so that an additional blowing device is not needed, and the foam eliminating method can be applied to various washing machines such as drum washing machines and pulsator washing machines. In addition, through the test, after the heater heats for about 15 minutes, the foam between the inner cylinder and the outer cylinder of the washing machine can be effectively removed, and even if the foam between the inner cylinder and the outer cylinder of the washing machine is not completely eliminated, the dehydration can be recovered to be normal.
In some embodiments, the cancellation method further comprises:
controlling the inner cylinder of the washing machine to rotate in the heating process of the heater; the rotating speed of the inner cylinder is smaller than a preset speed threshold.
Specifically, when the heater is controlled to heat, the inner cylinder of the washing machine is controlled to rotate, so that the temperature generated by heating of the heater can be spread more quickly by matching with the rotation of the inner cylinder of the washing machine and the heating action of the heater, foam between the inner cylinder and the outer cylinder of the washing machine can be eliminated quickly, and the foam elimination efficiency between the inner cylinder and the outer cylinder of the washing machine is further improved.
It will be appreciated that the drum is rotated at a high speed during normal spin-drying of the washing machine. When the washing machine cannot normally dehydrate, the inner cylinder cannot rotate at a high speed, but the inner cylinder can be controlled to rotate at a low speed, namely, the rotating speed of the inner cylinder corresponding to the embodiment is smaller than a preset speed threshold. The preset speed threshold may be set according to a specific actual situation, which is not limited and not described in detail.
In some embodiments, the cancellation method further comprises:
the water level in the washing machine is obtained in real time in the heating process of the heater;
when the water level in the washing machine is lower than the upper surface of the heater, the water is replenished into the washing machine until the water level in the washing machine is lower than the heater.
Specifically, the water level monitoring device can be arranged at a corresponding position in the washing machine barrel, and the water level L in the washing machine barrel is obtained in real time in the heating process of the heater, so that the water level L in the washing machine barrel is detected in real time, and once the water level L in the washing machine barrel is detected to be lower than the upper surface L of the heater h When the water is supplied into the washing machine barrel until the water level L in the washing machine barrel is lower than the upper surface L of the heater h And the heater is prevented from being burned and damaged.
The heater is arranged between the inner cylinder and the outer cylinder, is higher than the bottom of the outer cylinder and is lower than the bottom of the inner cylinder. Wherein water is fed into the washing machine barrel until the water level L exceeds the upper surface L of the heater h And is lower than the bottom of the inner cylinder to be the optimal water level, so that the heating time can be shortened while the boiling of water in the washing machine cylinder is realized.
In other embodiments, the water level L of the washing machine may be higher than the bottom of the inner tub, which is not limited by the disclosed embodiments.
In some embodiments, the cancellation method further comprises:
the water temperature in the washing machine is obtained in real time in the heating process of the heater;
when the water temperature in the washing machine barrel exceeds a second preset temperature value, controlling a small amount of water to enter the washing machine to wash the detergent box and the water inlet pipeline of the washing machine; wherein the second preset temperature value is greater than or equal to 50 ℃ and less than or equal to 100 ℃.
Specifically, after the heater heats for a period of time, foam in the washing machine can reversely pour into the detergent box and the water inlet pipeline of the washing machine, so that user experience is affected. The embodiment of the disclosure detects and acquires the water temperature Tw in the washing machine in real time in the heating process of the heater, and detects that the water temperature Tw exceeds a second preset temperature value T after heating for a period of time h And then, a small amount of water is fed into the washing machine barrel so as to wash foam generated in the detergent box and the water inlet pipeline, and the user experience is optimized. Wherein the second preset temperature value T h At 50-100 deg. to produce a small amount of water vapor in the washing machine barrel for flushing the foam in the detergent box and the water inlet pipeline.
The water inflow amount for flushing is not particularly limited, and the detergent box and the water inflow pipeline of the washing machine can be ensured to be flushed completely by reversely-filled foam.
In some embodiments, after controlling the heater to heat, further comprising:
after a preset time interval, the dewatering program is controlled to restart or continue to execute;
acquiring the state of a dehydration motor in the washing machine;
and controlling the static of the washing machine to eliminate foam when judging that the resistance of the dewatering motor still exceeds a preset value and/or is overloaded.
Specifically, after the heater is controlled to heat for a preset time interval, the dewatering program is controlled to restart or continue to execute, and the motor dewatering is recovered to be normal because the foam, especially the foam between the inner cylinder and the outer cylinder, is removed mostly. When the resistance of the dewatering motor still exceeds the preset value and/or is overloaded, namely the dewatering motor still cannot dewater, the static defoaming program of the washing machine can be controlled to start, and foam is naturally eliminated through long-time static, so that the dewatering motor can dewater normally.
Alternatively, when it is determined that the dehydration motor is still unable to dehydrate, the heater may be controlled to repeatedly heat at this time, and specifically, the heating process may be repeatedly performed, for example, three times. If the dehydration motor still cannot dehydrate after repeating the heating for three times, starting a standing defoaming program of the washing machine, and naturally eliminating foam through standing for a long time so as to enable the dehydration motor to dehydrate normally.
Based on the above embodiments, fig. 2 schematically illustrates a specific flow chart of a method for eliminating foam of a washing machine according to an embodiment of the present disclosure, which may be performed by the apparatus for eliminating foam of a washing machine according to an embodiment of the present disclosure.
