Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a cleaning method of a washing machine is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The washing machine is capable of operating in a tub cleaning mode. The cartridge cleaning mode comprising: and a dewatering stage with water, namely a stage of starting dewatering under the condition that water exists in the cylinder, so that the inner cylinder rotates and simultaneously drives water flow to rotate upwards to clean the inner cylinder and the outer cylinder. The cleaning method of the washing machine includes: step S110 to step S140.
In step S110, in a case where the washing machine operates in the dehydration with water stage in the tub cleaning mode, a current rotation speed of the washing machine is acquired.
At step S120, it is determined whether the current rotation speed of the washing machine reaches a set rotation speed at a rotation speed step to which the current rotation speed belongs.
Wherein, the rotational speed gear of washing machine includes: the first gear to the Nth gear, wherein N is a positive integer. The set rotating speed is the rotating speed when the frequency of the washing machine at the current rotating speed exceeds the resonance frequency of the rotating speed gear to which the current rotating speed belongs.
In the related scheme, when the rotating speed is greater than the resonant frequency, the rotating speed is about 200 revolutions and 300 revolutions. In the scheme of the invention, skipping the resonance point of the pulsator washing machine at low speed means that water is fed after the frequency of the rotating speed of the washing machine is greater than the resonance frequency. If the resonance frequency is not skipped, the water flow may be rotated to cause resonance noise or the eccentricity may be too large to cause dehydration failure.
In step S130, in case that it is determined that the current rotation speed of the washing machine reaches the set rotation speed, controlling the washing machine to keep the current rotation speed running, and controlling the washing machine to supply water.
In step S140, during the dewatering with water after the water is supplied to the washing machine, the dewatering with water is adjusted according to at least one of the operating current of the washing machine and the operating duration of the washing machine at the current rotation speed, so that the water flow in the dewatering with water can flow between the inner drum and the outer drum of the washing machine at a set flow rate.
The invention provides a barrel cleaning control method of a washing machine, which at least aims to solve the problem of eccentricity of the washing machine during dewatering with water of the washing machine.
In some embodiments, the operating current of the washing machine comprises: at least one of a present current of the washing machine, and a current variation value of the present current of the washing machine.
In step S140, the dewatering process of the washing machine with water is adjusted according to at least one of the operating current of the washing machine and the duration of the washing machine operating at the current rotation speed, including any one of the following adjustment situations:
the first regulation case: and under the condition that the current change value of the current of the washing machine reaches a set current change threshold value under the rotation speed gear to which the current rotation speed belongs, adjusting the current water inlet mode of the washing machine to be a set intermittent water inlet mode. The intermittent water inlet mode is a water inlet mode for water inlet according to a set interval time.
The second regulation case: and under the condition that the current of the washing machine reaches a set current threshold value under a rotation speed gear to which the current rotation speed belongs, controlling the washing machine to stop water inflow, and readjusting the water inflow condition of the washing machine according to the current rotation speed of the washing machine.
The third regulation case: and under the condition that the running duration time of the washing machine at the current rotating speed reaches a set time threshold value at a rotating speed gear to which the current rotating speed belongs, controlling the washing machine to stop water inflow, and readjusting the water inflow condition of the washing machine according to the current rotating speed of the washing machine.
In the solution of the invention, the gimbal is only active when the rotation speed is higher than the resonance frequency, considering that the gimbal generally acts in the opposite way when the spinning speed is low. Therefore, the high rotating speed is divided into 1 gear, 2 gears, 3 gears and gears, then the drain pipe is suspended to prevent water flow from flowing out, so that the maximum current when the water is taken for dehydration and stable dehydration can be determined, the rotating speed of the washing machine is adjusted to the gears of the rotating speed, water is slowly added, the water flow uniformly rotates along with the washing machine, and the maximum water inflow which can be borne by stable operation of the washing machine with the rotating speed is injected. And meanwhile, recording the magnitude of the current value when the maximum water inflow is kept in stable operation, and recording data as I. And when the current threshold value is detected at the set rotating speed of the current gear, entering the set rotating speed of the next gear.

... ...
The water flow of a common user home is not fixed, the water discharge amount is far more than the water inlet amount when the water is dehydrated, and when the dehydration reaches a set rotating speed, the water is possibly fed until the current threshold value meets the condition and enters the next rotating speed, so that when the set rotating speed is reached, the rotating speed is kept for feeding water for a certain time, and if the set time is not reached, the next set rotating speed is automatically jumped.
Set rotational speed Maximum run time at this speed
1 st gear T1

In addition, as the water flow of a common user home is not fixed, the water inlet amount is far more than the water discharge amount when water is possibly carried for dehydration, a large amount of water enters a cylinder rotating at a high speed, and the water is too much, so that the water can not uniformly disperse and rotate due to the centrifugal force at the first time, and the water flow causes eccentricity to cause dehydration failure. The change value of the detection current over a certain time is increased. Therefore, the high rotating speed is divided into 1 gear, 2 gears, 3 gears and each gear, then the drain pipe is suspended to prevent water flow from flowing out, the rotating speed of the washing machine is adjusted to each rotating speed gear, water enters according to different water inlet rates, the fastest water inlet rate capable of stably dewatering under different set rotating speed gears is obtained, the current change value delta I is recorded, when the current change value of the corresponding rotating speed gear reaches a threshold value, water stops entering, and the mode is converted into an intermittent water inlet mode.

According to the scheme of the invention, the current magnitude and the current change value are utilized to determine the dehydration rotation speed, the dehydration program feeds water into the washing machine during dehydration, the inner and outer cylinders are washed by the water flow of the water inlet, and the inner and outer cylinders are washed by the high-speed rotating water flow, so that the cleaning effect can be improved.
In some embodiments, a specific process of readjusting the water inlet condition of the washing machine according to the current rotation speed of the washing machine is further described with reference to a flowchart of an example of readjusting the water inlet condition of the washing machine according to the current rotation speed of the washing machine in the method of the present invention shown in fig. 2, including: step S210 to step S230.
And step S210, determining whether the rotation speed gear to which the current rotation speed of the washing machine belongs reaches a set highest rotation speed gear.
Step S220, if it is determined that the rotation speed gear to which the current rotation speed of the washing machine belongs has reached the set highest rotation speed gear, determining that the dewatering stage with water is finished, that is, determining that the washing machine has completed the dewatering stage with water, and controlling the washing machine to exit the dewatering process with water.
Step S230, if it is determined that the rotation speed gear to which the current rotation speed of the washing machine belongs does not reach the set highest rotation speed gear, entering a next gear of the rotation speed gear of the washing machine, and re-determining whether the current rotation speed of the washing machine reaches the set rotation speed at the rotation speed gear to which the current rotation speed belongs.
Fig. 4 is a flowchart illustrating a method for controlling drum cleaning of a washing machine according to an embodiment of the present invention. As shown in fig. 4, the drum cleaning control method of the washing machine includes:
step 1, entering a dewatering stage with water in a cylinder self-cleaning mode.
And 2, starting to detect whether the current rotating speed reaches the set rotating speed, and executing the step 3 if the current rotating speed reaches the set rotating speed. Otherwise, step 2 waits, that is, whether the current set rotating speed is reached is continuously detected.
And 3, when the dewatering rotating speed is detected to reach the set rotating speed, keeping the rotating speed to continuously operate, and controlling the water inlet valve to start water inlet.
And 4, after the dewatering rotating speed is detected to reach the set rotating speed, detecting the current I while starting water inflow, detecting three parameters of a current change value delta I and the continuous operation time T for keeping the current rotating speed, and controlling the drum cleaning process of the washing machine in the dewatering stage with water according to the three parameters, specifically referring to any one of the steps 41, 42 and 43.
And step 41, if the current change value Δ I (specifically, the current change rate value) reaches a corresponding set threshold value, the program enters an intermittent water inlet mode.
Specifically, because the water flow rate per user is not fixed. The intermittent dehydration means that when the water inflow of a user at home is excessive, if the current rotating speed is low during the dehydration acceleration process of the washing machine and cannot provide enough centrifugal force, the water flow causes eccentricity. At this time, the current 1 increases rapidly, and the current change value Δ I also increases. Therefore, when the increase of the current change value delta I is detected to reach the set threshold value, the water feeding is stopped for a period of time, and the water feeding is continued after the dehydration rotating speed is increased. The period of pause is not required to be a specific time.
And 42, when the current value I reaches the corresponding set threshold value, the program enters the next set rotating speed gear.
And 43, when the continuous operation time T for keeping the current rotating speed reaches the corresponding set threshold value, the program enters the next set rotating speed gear.
And 5, repeatedly keeping the program to reach the set highest rotating speed gear, finishing the dewatering stage with water, and automatically entering a normal dewatering flow. For example: and when the current value I or the continuous operation time T for keeping the current rotating speed reaches a corresponding set threshold value, stopping water inflow, detecting whether the current rotating speed reaches a highest set rotating speed gear, and if so, determining that the dewatering stage with water is finished. Otherwise, the program enters the next set rotating speed gear and returns to the step 2.
According to the scheme, the dewatering rotating speed is adjusted through the judgment of the current magnitude in the cylinder cleaning mode of the washing machine, different water inflow is increased according to different rotating speeds in the dewatering process, so that the washing machine cannot be subjected to dewatering failure due to overlarge eccentricity caused by water flow in the dewatering process with water, and the cleaning effect can be improved.
By adopting the technical scheme of the embodiment, in the drum cleaning mode of the washing machine, water enters after the frequency of the rotating speed of the washing machine is greater than the resonance frequency in the water-carrying dehydration stage, and the water inflow is adjusted according to the current magnitude and the rotating speed duration under the condition of water-carrying dehydration, so that water flow can flow between the inner cylinder and the outer cylinder at a high speed. Therefore, the water intake is adjusted according to the difference of the rotating speed in the water-carrying dehydration stage of the barrel cleaning mode of the washing machine, the dehydration failure caused by the fact that the eccentricity is too large in the water-carrying dehydration process of the washing machine can be avoided, and the washing effect can be favorably improved.
According to an embodiment of the present invention, there is also provided a cleaning device of a washing machine corresponding to a cleaning method of the washing machine. Referring to fig. 3, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The washing machine is capable of operating in a tub cleaning mode. The cartridge cleaning mode comprising: and a dewatering stage with water, namely a stage of starting dewatering under the condition that water exists in the cylinder, so that the inner cylinder rotates and simultaneously drives water flow to rotate upwards to clean the inner cylinder and the outer cylinder. The cleaning device of the washing machine includes: an acquisition unit 102 and a control unit 104.
Wherein the obtaining unit 102 is configured to obtain a current rotation speed of the washing machine in case that the washing machine is operated in a dewatering stage with water in the drum cleaning mode. The specific functions and processes of the acquiring unit 102 are referred to in step S110.

Wherein, the rotational speed gear of washing machine includes: the first gear to the Nth gear, wherein N is a positive integer. The set rotating speed is the rotating speed when the frequency of the washing machine at the current rotating speed exceeds the resonance frequency of the rotating speed gear to which the current rotating speed belongs.
In the related scheme, when the rotating speed is greater than the resonant frequency, the rotating speed is about 200 revolutions and 300 revolutions. In the scheme of the invention, skipping the resonance point of the pulsator washing machine at low speed means that water is fed after the frequency of the rotating speed of the washing machine is greater than the resonance frequency. If the resonance frequency is not skipped, the water flow may be rotated to cause resonance noise or the eccentricity may be too large to cause dehydration failure.
The control unit 104 is further configured to control the washing machine to keep running at the current rotation speed and control the washing machine to feed water if it is determined that the current rotation speed of the washing machine reaches the set rotation speed. The specific function and processing of the control unit 104 are also referred to in step S130.
The control unit 104 is further configured to, during the dewatering with water after water is supplied to the washing machine, adjust the dewatering with water of the washing machine according to at least one of the operating current of the washing machine and the duration of the operation of the washing machine at the current rotation speed, so that the water flow during the dewatering with water of the washing machine can flow between the inner drum and the outer drum of the washing machine at a set flow rate.

the first regulation case: the control unit 104 is further specifically configured to adjust a current water inlet mode of the washing machine to a set intermittent water inlet mode when a current change value of a current of the washing machine reaches a set current change threshold value at a rotation speed gear to which the current rotation speed belongs. The intermittent water inlet mode is a water inlet mode for water inlet according to set interval time.
The second regulation case: the control unit 104 is further specifically configured to control the washing machine to stop water inflow and readjust the water inflow of the washing machine according to the current rotation speed of the washing machine when the current of the washing machine reaches the set current threshold value in the rotation speed gear to which the current rotation speed belongs.

In the solution of the invention, the gimbal is only active when the rotation speed is higher than the resonance frequency, considering that the gimbal generally acts in the opposite way when the spinning speed is low. Therefore, the high rotating speed is divided into 1 gear, 2 gears, 3 gears and gears, then the drain pipe is suspended to prevent water flow from flowing out, the rotating speed of the washing machine is adjusted to the gears of the rotating speed, water is slowly added, the water flow uniformly rotates along with the washing machine, and the maximum water inflow which can be borne by the stable operation of the washing machine with the rotating speed is injected.

In addition, as the water flow of a common user home is not fixed, the water inlet amount is far higher than the water discharge amount when the water is dehydrated with the water, a large amount of water enters the cylinder rotating at a high speed, the water cannot be uniformly dispersed and rotated due to the centrifugal force at the first time because of too much water, and the dehydration failure is caused by the eccentricity of the water flow. The change value of the detection current over a certain time is increased. Therefore, the high rotating speed is divided into 1 gear, 2 gears, 3 gears, right gears and all gears, then the drain pipe is suspended to prevent water flow from flowing out, the rotating speed of the washing machine is adjusted to all the rotating speed gears, water is fed according to different water feeding rates, the fastest water feeding rate which can stably dewater under different set rotating speed gears is obtained, the current change value delta I is recorded, when the current change value of the corresponding rotating speed gear reaches a threshold value, water feeding is stopped, and the intermittent water feeding mode is converted.
