Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a method for controlling dehydration of a washing machine according to an embodiment of the present invention, where the method may be performed by a dehydration control device of a washing machine, where the device may be implemented by software and/or hardware, where the device may be configured in a washing machine, and where the method may be applied to a scenario where the washing machine performs dehydration without reaching a preset maximum speed (high speed). The washing machine can be a variable-frequency washing machine, optionally an upper-drainage variable-frequency impeller washing machine, wherein the upper-drainage variable-frequency impeller washing machine can drain water through a drainage pump in a dewatering process.
As shown in fig. 1, the technical solution provided by the embodiment of the present invention includes:
s110: in the non-resonance dehydration stage, controlling the washing machine to accelerate to a first speed at a first acceleration and rotate for a first set time at the first speed; the first speed is less than a preset maximum speed of dewatering, and the first acceleration is less than or equal to a preset acceleration threshold.
In the embodiment of the present invention, the preset maximum speed may be a speed corresponding to a high-speed rotation of the washing machine. In the non-resonance dehydration stage, the rotating speed of the washing machine is accelerated from a certain speed to a first speed, and a formed speed interval does not contain a resonance interval of the speed. The preset acceleration threshold may be an acceleration threshold corresponding to no bubbles generated when the washing machine accelerates to a preset maximum speed. When the first acceleration is smaller than or equal to the preset acceleration threshold, no foam is generated in the process that the washing machine accelerates to the first speed from the first acceleration in the non-resonance dehydration stage. Alternatively, the preset acceleration threshold may be 10 rpm/s.
In the embodiment of the present invention, since the first speed is less than the preset maximum speed of the dehydration, the washing machine does not reach the speed of the high-speed rotation in the non-resonance dehydration stage. In the non-resonance dehydration stage, if the acceleration of the washing machine is too large, foam is easily generated when the washing machine dehydrates. Especially, in the initial dewatering stage, the water content of the clothes is high, the inner barrel has more water amount due to overlarge acceleration, the water is drained (by a drainage pump) untimely, the swing of the inner barrel causes foam, once more foam is generated, the power of a motor is increased, the preset maximum speed is not easy to reach, the high speed cannot be reached, and the water content of the clothes is high. Therefore, in the non-resonance dehydration stage, the washing machine needs to be controlled to accelerate at the first acceleration which is less than or equal to the preset acceleration threshold, the time for reaching the preset maximum speed is prolonged, the water in the inner barrel of the washing machine can be discharged in time, and for the upper-drainage variable-frequency washing machine, the water can be discharged in time by the drainage pump.
In one implementation of the embodiment of the present invention, the first acceleration may be optionally determined based on a moisture content of the laundry or a fabric of the laundry. Wherein, in case that the first acceleration is less than or equal to the preset acceleration threshold range, the larger the water content of the laundry is, the smaller the first acceleration may be, so that the generation of bubbles may be avoided; the first acceleration may be greater if the moisture content of the laundry is smaller, by improving the efficiency of the dehydration. If the surface fabric of clothing is the surface fabric that the water content is great, then first acceleration can be less, if the surface fabric of clothing is the surface fabric that the water content is less, then first acceleration can be great, can avoid the production of foam, also can improve the efficiency of dehydration.
S120: in the resonance dehydration stage, controlling the washing machine to accelerate to a second speed at a second acceleration and rotate for a second set time at the second speed; wherein the first acceleration is less than the second acceleration; the second speed is less than a preset maximum speed.
In the embodiment of the invention, in the resonance dehydration stage, the washing machine accelerates from a certain speed to a second speed, and a formed speed interval comprises the speed of the resonance interval. The maximum speed of the formed speed interval may be greater than the maximum speed of the resonance interval, and the minimum speed of the formed speed interval may be less than the minimum speed of the resonance interval.
In an embodiment of the invention, the second acceleration may be greater than 45rpm/s, wherein rpm is a number of revolutions per minute, wherein the ratio of the second acceleration to the first acceleration may be between 6-8. In the resonance dewatering stage, resonance phenomenon may occur, and in order to make the rotation speed of the washing machine exceed the resonance interval as soon as possible, the washing machine may be accelerated to the second speed at the second acceleration higher than the first acceleration, so that the washing machine may get rid of the resonance phenomenon quickly.
According to the technical scheme provided by the embodiment of the invention, the washing machine is controlled to accelerate to the first speed at the first acceleration which is less than or equal to the preset acceleration threshold value in the non-resonance dehydration stage and rotate for the first set time at the first speed, so that the time of reaching the preset maximum speed of the washing machine can be prolonged, more foams can be timely drained, and the condition of high water content of clothes can be avoided.
Fig. 2a is a flowchart of a dewatering control of a washing machine according to an embodiment of the present invention, where, optionally, the non-resonant dewatering stage includes a first non-resonant dewatering stage, a second non-resonant dewatering stage, and a third non-resonant dewatering stage;
the resonance dehydration stage comprises a first resonance dehydration stage and a second resonance dehydration stage;
the first resonant dehydration stage is between a second non-resonant dehydration stage and a third non-resonant dehydration stage, the second resonant dehydration stage being after the third non-resonant dehydration stage.
Optionally, the controlling the washing machine to accelerate to a first speed at a first acceleration and rotate at the first speed for a first set time includes:
controlling the washing machine to accelerate from 0 to a first target speed at a first target acceleration and rotate at the first target speed for a first target time in the first non-resonance dehydration stage;
controlling the washing machine to accelerate from the first target speed to a second target speed at a second target acceleration and rotate for a second target time at the second target speed in the second non-resonance dehydration stage;
controlling the washing machine to accelerate from a third target speed to a fourth target speed at a fourth target acceleration and rotate for a fourth target time at the fourth target in the third non-resonance dehydration stage; wherein the third target speed is the speed of the constant stage in the first resonance dehydration stage; wherein the first target acceleration, the second target acceleration, and the fourth target acceleration are less than the preset acceleration threshold.
Optionally, the controlling the washing machine to accelerate to a second speed at a second acceleration and rotate at the second speed for a second set time includes:
controlling the washing machine to accelerate from the second target speed to the third target speed at a third target acceleration and rotate at the third target speed for a third target time in the first resonance dehydration stage;
controlling the washing machine to accelerate from the fourth target speed to a fifth target speed at a fifth target acceleration and rotate for a fifth target time at the fifth target speed in the second resonance dehydration stage; the third target acceleration is greater than the first target acceleration, the second target acceleration, and the fourth target acceleration; the fifth target acceleration is greater than the first target acceleration, the second target acceleration, and the fourth target acceleration.
As shown in fig. 2a, the technical solution provided by the embodiment of the present invention includes:
s210: and in the first non-resonance dehydration stage, controlling the washing machine to accelerate from 0 to a first target speed at a first target acceleration and rotate at the first target speed for a first target time, wherein the first target speed is less than the preset acceleration threshold.
In the embodiment of the present invention, for example, fig. 2b shows the speed variation with time when the washing machine dehydrates, and as shown in fig. 2b, the rotation stage of the washing machine in the time interval of 0-t1 corresponds to the first non-resonance dehydration stage. Alternatively, t1 may be the 10 th s. At this stage, the washing machine is accelerated from 0 to the first target speed v1 at the first target acceleration a 1. Wherein, optionally, the first target acceleration a1 may be 5rpm/s, and the first target speed v1 may be 30 rpm. The first target time may be determined according to the total time of the phase time interval and the time of the acceleration phase.
In the embodiment of the invention, when the washing machine rotates in the time interval of 0-t1, the water content of the clothes is higher, the first target acceleration a1 is controlled to be less than or equal to the preset acceleration threshold (the first target acceleration a1 is controlled to be a smaller value), the time for the washing machine to reach the preset maximum speed can be prolonged, and the water in the inner barrel can be discharged in time. If this stage acceleration is too big then can lead to the interior bucket of washing machine to have more water yield, because the swing of interior bucket produces the foam, can lead to motor power to increase, washing machine is difficult to reach and presets maximum rotational speed, leads to the clothing water content after the dehydration higher, and the clothing dehydration is not thorough. Therefore, in the first off-resonance dehydration stage, the first target acceleration needs to be controlled to be less than or equal to the preset acceleration threshold, so as to avoid the situation that the water content of the dehydrated clothes is high due to the generation of foam.
S220: controlling the washing machine to accelerate from the first target speed to a second target speed at a second target acceleration and rotate for a second target time at the second target speed in a second non-resonance dehydration stage; the second target acceleration is less than or equal to the preset acceleration threshold.
In the embodiment of the present invention, as shown in fig. 2b, the washing machine rotates in the time interval t1-t2 corresponding to the second off-resonance dehydration stage, alternatively, t1 may be the 10 th s, and t2 may be the 20 th s. At this stage, the washing machine is accelerated from the first target speed v1 to the second target speed v2 at the second target acceleration a 2. The second target acceleration may be the same as or different from the first target acceleration. Alternatively, the second target acceleration may be 5rpm/s, and the second target speed v2 may be 60 rpm. The second target time may be determined according to the total time of the phase time interval and the time of the acceleration phase.
In the embodiment of the invention, the water content of the clothes is still high in the stage that the washing machine rotates in the time interval of t1-t2, so that the second target acceleration a2 needs to be controlled to be a smaller value, namely the second target acceleration a2 is controlled to be less than or equal to the preset acceleration threshold value, the time that the washing machine reaches the preset maximum speed is prolonged, the water in the inner barrel is discharged in time, and a large amount of foam is avoided.
It should be noted that the first non-resonant dehydration stage and the second non-resonant dehydration stage can be combined into one non-resonant dehydration stage. For example, the washing machine is controlled to accelerate from 0 to a second target speed at a first target acceleration.
S230: and controlling the washing machine to accelerate from the second target speed to the third target speed at a third target acceleration and rotate at the third target speed for a third target time in the first resonance dehydration stage.
In the embodiment of the present invention, for example, as shown in fig. 2b, the rotation stage of the washing machine at the time interval of t2-t3 corresponds to the first resonance dehydration stage. Wherein the washing machine speed interval at this stage may include a first resonance interval of the speed. In this stage, the washing machine needs to rapidly pass through the stage because the motor rotation frequency generates a resonance phenomenon with its own natural frequency, and thus, the washing machine is controlled to accelerate from the second target speed v2 to the third target speed v3 at a greater third target acceleration a 3. Alternatively, t3 may be 23s, a3 may be greater than 45rpm/s, alternatively, a3 may be 100rpm/s, the second target speed may be 60rpm, and the third target speed may be 120 rpm. The first resonance interval may be 80rpm to 120 rpm. The washing machine is controlled to accelerate by controlling the washing machine with a larger third target acceleration, so that the washing machine can rapidly pass through the first resonance dehydration stage, the resonance time can be reduced, and the washing efficiency is improved.
S240: and in the third non-resonance dehydration stage, controlling the washing machine to accelerate from a third target speed to a fourth target speed at a fourth target acceleration, and rotating for a fourth target time at the fourth target acceleration, wherein the fourth target acceleration is less than or equal to a preset acceleration threshold value.
In the embodiment of the present invention, for example, as shown in fig. 2b, the phase in which the washing machine rotates in the time interval t3-t4 corresponds to the third non-resonant dehydration phase, and the speed interval of the washing machine in the phase does not include the resonant interval of the speed. Alternatively, t3 may be the 23 st and t4 may be the 100 th. At this stage, the washing machine is accelerated from the first target speed v3 to the second target speed v4 at the fourth target acceleration a 4. The fourth target acceleration may be the same as or different from the first target acceleration, and the fourth acceleration may be set according to the flow rate of the drainage pump, or may be set according to an actual situation. Alternatively, the fourth target acceleration may be 5rpm/s, and the fourth target speed v4 may be 170 rpm.
S250: and controlling the washing machine to accelerate from the fourth target speed to a fifth target speed at a fifth target acceleration in the second resonance dehydration stage, and rotating for a fifth target time at the fifth target speed.
As shown in fig. 2b, the washing machine rotates at the time interval t4-t5 corresponding to the second resonance dehydration stage, and the washing machine speed interval at this stage includes the second resonance interval of the rotation speed. Alternatively, t4 may be the 100 th s, and t5 may be the 150 th s. Like the first resonance dehydration stage, in which the resonance phenomenon is generated, it is required to rapidly pass through the stage, and thus, the washing machine is controlled to accelerate from the fourth target speed v4 to the fifth target speed v5 at the relatively large fifth target acceleration a 5. Alternatively, a5 may be greater than 45rpm/s, alternatively, a5 may be 100rpm/s and v5 may be 350 rpm. The washing machine is controlled to accelerate by controlling the washing machine with a larger fifth target acceleration, so that the washing machine can rapidly pass through the second resonance dehydration stage, the resonance time can be reduced, and the washing efficiency is improved.
It should be noted that the dehydration phase shown in fig. 2b further includes another non-resonance dehydration phase, i.e. a phase corresponding to a time interval from t5 to t6, in which the washing machine can be controlled to accelerate from a fifth target speed v5 to a sixth target speed v6 at a sixth acceleration a6 and move for a sixth target time at a sixth target speed v6, where the sixth target speed may be a preset maximum speed. Alternatively, a6 may be 10rpm/s, t5 may be 150 th s, t6 may be 180 th s, and v6 may be 450 rpm. This is only an example and may be divided in other ways, whether to include the last non-resonant dehydration stage may be set as needed, and the time corresponding to each stage and the speed corresponding to each stage may be determined according to the difference of the laundry load.
Fig. 3 is a flowchart of a dewatering control method for a washing machine according to an embodiment of the present invention, where in this embodiment, optionally, in the second non-resonant dewatering stage, controlling the washing machine to accelerate from the first target speed to a second target speed at a second target acceleration includes:
in a second non-resonance dehydration stage, if the water level of the inner barrel of the washing machine is detected to be smaller than a set water level or the foam quantity of the inner barrel is detected to be smaller than a set foam quantity, the washing machine is controlled to accelerate from the first target speed to a second target speed at a second target acceleration; wherein the second target acceleration is greater than the first target acceleration.
As shown in fig. 3, the technical solution provided by the embodiment of the present invention includes:
s310: and in the first non-resonance dehydration stage, controlling the washing machine to accelerate from 0 to a first target speed at a first target acceleration and rotate at the first target speed for a first target time, wherein the first target speed is less than the preset acceleration threshold.
S320: in a second non-resonance dehydration stage, if the water level of the inner barrel of the washing machine is detected to be smaller than a set water level or the foam quantity of the inner barrel is detected to be smaller than the set foam quantity, the washing machine is controlled to accelerate from the first target speed to a second target speed at a second target acceleration speed and rotate for a second target time at the second target speed; wherein the second target acceleration is greater than the first target acceleration.
In the embodiment of the invention, the water level or the foam amount in the inner barrel of the washing machine can be detected through the sensor, when the water level of the inner barrel is lower than the set water level, the water in the inner barrel is less after the first non-resonance dehydration stage, the water can be discharged by the drainage pump in time, and the foam is not easy to generate, so that the second target acceleration in the second non-resonance dehydration stage can be controlled to be larger than the first target acceleration, the washing machine can reach the preset maximum rotating speed as soon as possible, and the dehydration efficiency is improved.
In the embodiment of the invention, when the foam amount of the inner barrel is less than the set foam amount, under the condition that the water discharge amount of the water discharge pump is not changed, the water amount of the inner barrel is less, the second target acceleration in the second non-resonance dehydration stage can be controlled to be greater than the first target acceleration, the time for the washing machine to reach the preset maximum rotating speed can be reduced, and the dehydration efficiency is improved.
Therefore, if the water level of the inner barrel of the washing machine is detected to be smaller than the set water level or the foam amount of the inner barrel is detected to be smaller than the set foam amount, the second target acceleration of the washing machine is controlled to be larger than the first target acceleration, and the dewatering efficiency can be improved.
