In the embodiment of the application, the rotation speed of the dewatering barrel after the speed is increased is adjusted through the vibration value of the dewatering barrel, so that the rotation speed of the dewatering barrel is accurately adjusted in the dewatering process, the vibration of the dewatering barrel is kept at the optimal vibration, and the vibration or noise of washing equipment in running is reduced.
The washing equipment is a washing machine, the washing machine comprises a shell, an outer barrel and an inner barrel are arranged in the shell, the inner barrel is rotatably arranged in the outer barrel, the inner barrel is a dehydration barrel, the dehydration barrel is controlled to rotate and dehydrate in response to a dehydration instruction, and the eccentric position of a load is acquired in the rotation process of the dehydration barrel; the dewatering instruction can be sent after the user triggers the designated dewatering key, or can be automatically triggered in a series of clothes cleaning processes. After the controller of the washing machine sends out a dehydration instruction, the washing machine controls the motor driving device to drive the dehydration barrel to rotate so as to carry out dehydration, and the washing machine always adopts the same uniform acceleration in the whole dehydration process.
The dewatering barrel is provided with an eccentric detection device and a vibration detection device, the eccentric detection device is used for detecting the eccentric position of a load, the vibration detection device is used for detecting the vibration value of the dewatering barrel, and further, the vibration detection device is used for detecting the axial vibration value and the radial vibration value of the dewatering barrel. The washing machine is provided with a control system, the control system is connected with an eccentric detection device and a vibration detection device, the eccentric detection device transmits the detected eccentric position of the load to the control system, the control system compares the eccentric position of the load with a preset interval, the vibration detection device transmits the detected vibration value of the dewatering barrel to the control system, and the control system compares the vibration value of the dewatering barrel with the preset vibration value, so that the control system controls a motor to operate and adjusts the rotating speed of the dewatering barrel.
When the dehydrating program ending signal is received, the dehydrating program is finished, so that the motor of the washing machine is controlled to stop rotating, gradually decelerate and idle for a certain time, then naturally stop, and when the time for stopping rotating reaches a certain preset time, a prompt is sent to prompt a user to pay attention to the fact that the dehydrating program is finished, clothes can be taken out from the washing machine, and the situation that the user places the clothes in the washing machine because the user does not know that the dehydrating program is finished is avoided. Specifically, the number of beeps is not limited to 6, but can be 2 or 3, and can be an alarm or a voice prompt.
As shown in fig. 1, in the embodiment of the present application, the dewatering tub rotates at a first rotation speed, after the eccentric position of the load is within a preset interval, the rotation speed of the dewatering tub is increased from the first rotation speed to a second rotation speed, the dewatering tub rotates at the second rotation speed for dewatering, the vibration value of the dewatering tub is compared with a preset vibration value, and if the vibration value is smaller than or equal to the preset vibration value, the rotation speed of the dewatering tub is adjusted.
In the embodiment of the application, after the washing machine enters a dewatering program, a preset rotating speed is given first, and the preset rotating speed is a first rotating speed, so that the dewatering barrel of the washing machine is controlled to rotate at the first rotating speed;
the step of obtaining the vibration value of the dewatering barrel specifically comprises the following steps: and acquiring the maximum vibration value of the dewatering barrel measured by the vibration detection device of the washing machine in a preset time period, and taking the average value of the maximum vibration values of the dewatering barrel in each rotation as the vibration value.
When the vibration detection device measures the maximum vibration value of each circle in the preset market and calculates the average value of the vibration values, the rotation of the dewatering barrel is controlled to dewater according to the relation between the average value of the vibration values and the preset vibration value, and the average value is selected to avoid the influence of measurement errors on the judgment result of the vibration values and the preset vibration value, so that the normal operation of the washing machine is influenced.
Different eccentric loads can generate different eccentricities, and the different eccentricities can cause different vibration of the whole machine under the condition of high-speed dehydration;
in the dehydration process, controlling the dehydration rotation speed of the dehydration barrel to accelerate to a second rotation speed, wherein the second rotation speed is a preset rotation speed which is larger than the first rotation speed, rotating for a certain preset time at the second rotation speed, and obtaining the vibration value of the dehydration barrel.
In the technical scheme, the dehydration rotating speed is controlled to be accelerated to the first rotating speed, and the first rotating speed is rotated for a certain preset time, and as the total weight of the clothes to be washed and the water in the initial dehydration stage is larger, larger eccentricity and vibration can be generated under the condition of high-speed dehydration, the vibration generated by the whole machine during working can be in a safe range by reasonably setting the dehydration rotating speed and the dehydration time in the initial stage while ensuring the dehydration effect, so that the condition that the vibration is overlarge and vibration faults occur due to the adoption of the larger dehydration speed is avoided.
The dehydration process is respectively a first stage and a second stage, wherein the first stage is used for controlling the dehydration rotating speed to accelerate to a first rotating speed and rotating for a certain preset time at the first rotating speed, and the second stage is used for determining whether to adjust the dehydration rotating speed according to the comparison result of the detected vibration value and the preset vibration value. The method adopts a mode of controlling the dehydration rotating speed in stages in the dehydration process, and further changes the dehydration speed acceleration curve in a targeted manner, so that the vibration of the whole machine in the dehydration process is reduced while the dehydration effect is ensured.
The time for dehydration at the first rotational speed is prolonged as much as possible, and the water content of the laundry is reduced to ensure the dehydration effect under the condition of small load.
According to the detected comparison result of the vibration value of the dewatering barrel and the preset vibration value, the dewatering speed is automatically controlled so as to achieve the optimal dewatering and balancing effects under different load conditions, namely, the dewatering speed is furthest improved while the vibration value generated during the dewatering operation of the whole machine is in a safe range, the dewatering effect is further improved, the running noise of the product and the noise interference to users and surrounding residents are reduced, the probability of vibration faults is reduced, and the usability and the market competitiveness of the product are improved.
The outer tub is fixed in the casing of the washing machine through the shock absorbing connector and the elastic connector. The damping connection is used for providing supporting force for the outer barrel on the one hand and relieving vibration of the outer barrel through mechanical damping on the other hand, so that vibration transmitted to the shell by the outer barrel is reduced. The elastic connecting piece can be a hanging spring and has the functions of shock absorption and fixation. The number of shock absorbing connectors and elastic connectors may be plural to provide a multi-point supporting force to the tub and to reduce vibration transmitted to the housing from the tub.
As shown in fig. 1, in the embodiment of the application, if the vibration value of the dewatering barrel is smaller than or equal to the preset vibration value, the rotation speed of the dewatering barrel is increased from the second rotation speed to the third rotation speed, and if the vibration value of the dewatering barrel is larger than the preset vibration value, the dewatering barrel still rotates to dewater at the second rotation speed.
In the embodiment of the application, when the determined vibration is a first vibration value, the corresponding target rotating speed is a first rotating speed, when the determined vibration is a second vibration value, the corresponding target rotating speed is a second rotating speed, and when the vibration is larger, the situation that larger noise and even safety accidents are generated due to overlarge vibration of the outer barrel is prevented by setting a lower rotating speed.
Further, the vibration value of the dewatering barrel comprises an axial vibration value and a radial vibration value of the dewatering barrel, the axial vibration value and the radial vibration value are compared with preset vibration values, and if the axial vibration value and the radial vibration value are smaller than or equal to the preset vibration values, the rotation speed of the dewatering barrel is increased from the second rotation speed to the third rotation speed.
And if one of the axial vibration value and the radial vibration value is smaller than or equal to the preset vibration value, the dehydration barrel rotates at a fourth rotating speed, and the fourth rotating speed is larger than the second rotating speed and smaller than the third rotating speed.
If the axial vibration value and the radial vibration value are both larger than the preset vibration value, the dehydration barrel still rotates at the second rotating speed for dehydration.
As shown in fig. 1, in the embodiment of the present application, the dewatering tub rotates at a first rotation speed, and if the eccentric position of the load is detected not to be within the preset interval, the dewatering tub is controlled to continue to rotate at the first rotation speed, and the water inlet of the washing device feeds water into the dewatering tub, so that the eccentric position of the load is within the preset interval;
and when the eccentric position of the load is detected to be in the preset interval, the rotating speed of the dewatering barrel is directly increased from the first rotating speed to the second rotating speed.
In the embodiment of the application, the rotating speed of the dewatering barrel is accurately regulated by detecting the eccentric position of the load, so that the vibration or noise of the washing equipment during operation is reduced.
It is easily understood that when the load of the laundry in the inner tub is not uniformly distributed along the inner tub wall, the centrifugal force in the circumferential direction of the dehydrating tub is not uniform. When the load capacity in the dewatering barrel is large and the eccentric capacity is large, the dewatering barrel is severely vibrated by the large centrifugal force, and large noise is generated; conventionally, the magnitude of the eccentric position is generally proportional to the magnitude of the dehydration noise. Therefore, the dehydration control can be performed according to parameters such as the eccentric position, and the like, with the aim of reducing the dehydration noise.
The preset interval can be determined according to the load weight, and one weight interval corresponds to one preset interval.
When the eccentric position of the load is in a corresponding preset interval, the clothes are not eccentric or have smaller eccentric, and the rotating speed of the dewatering barrel can be increased to a second rotating speed; when the eccentric position of the load is detected not to be in the preset interval, the fact that the clothes have larger eccentricity is indicated, and certain measures are needed to be taken to adjust the eccentricity of the load, so that the eccentricity of the load is eliminated, and the phenomenon that the clothes are gathered into a cluster and cannot be dehydrated is avoided.
The preset vibration value is obtained by carrying out a large number of tests on different types of loads and carrying out data statistics processing;
in order to solve the problems that the eccentricity of clothes is large or the clothes are obviously entangled and the like, the application adopts an emergency coping mode in the eccentric detection stage, namely, when the eccentricity is far beyond the maximum value of a preset interval, the eccentric detection is directly stopped.
The measure for adjusting the eccentricity of the load is to control the dewatering barrel to rotate at a first rotation speed, control the dewatering barrel to stop rotating after the eccentric position of the load rotates to the lower part of the water inlet, and control the dewatering barrel to rotate again at the first rotation speed after the water inlet stops water inlet and water with the same amount as the eccentricity of the load is fed into the dewatering barrel, and detect whether the eccentric position of the load is in a preset interval.
The eccentric position of the load is controlled to be below the water inlet, so that water can be fed into the dewatering barrel which stops rotating accurately at the eccentric position, the water inlet only needs to eliminate the eccentric amount, namely, the water inlet feeds water with the same amount as the eccentric amount of the load into the dewatering barrel, the load can be uniformly distributed in the dewatering barrel through feeding water into the barrel, the eccentric of the load is eliminated, after water feeding is finished, the eccentric of the load is detected again, and whether the eccentric position of the load is in a preset interval is judged, so that the dewatering barrel can be accelerated.
In the embodiment of the application, in the process of adjusting the eccentric position of a load, setting the maximum number of times of one-time dehydration eccentric detection of the dehydration barrel as m, and directly discharging water in the dehydration barrel when the detection number of times reaches m and the eccentric position of the load is still not in a preset interval, and controlling the dehydration barrel to rotate at a first rotation speed until dehydration is finished.
In the embodiment of the present application, in solving the problem of occurrence of serious uneven distribution, a maximum number of times of eccentric detection of one laundry washing course may be set to m in consideration of the overall running time of the laundry washing course. When the detection times reach m and the eccentric value is still larger than the heavy eccentric value, directly discharging the washing water, and then controlling the dewatering barrel to run at the rotating speed b until the clothes washing program is finished. That is, when the number of times of detection reaches the extreme value, a control manner of forcibly discharging the washing water and spin-drying at a low speed may be selected to avoid the high-speed resonance point, and it is desirable to be able to complete the washing control process as soon as possible while avoiding the low-speed resonance point.
The foregoing description is only a preferred embodiment of the present application, and the present application is not limited to the above-mentioned embodiment, but is not limited to the above-mentioned embodiment, and any simple modification, equivalent change and modification made by the technical matter of the present application can be further combined or replaced by the equivalent embodiment without departing from the scope of the technical solution of the present application.
