In conclusion, different problems exist for different eccentric amounts, and the product has the obvious condition that a low-speed barrel body impacts a box body or cannot be dehydrated, so that a difficult point in the industry is also a pain point influencing user experience, and the problem needs to be solved urgently.

The two acceleration sensors are arranged on the inner drum of the washing machine, the amplitudes of the drum in the front-back direction and the left-right direction of the box body are tested through the two acceleration sensors, and the average amplitude of each test is carried out in the front-back direction and the left-right direction, so that compared with the scheme of only arranging one acceleration sensor, the two acceleration sensors are arranged, the measured amplitude is higher in precision.
The formula of the amplitude value obtained by the acceleration is as follows:
alternatively, for the arrangement of the sensors, the central angle between two adjacent sensors in the circumferential direction may be an acute angle, such as 60 °, 70 °, 80 °, and so on, which facilitates the measurement of the amplitude values of the buckets from a plurality of angles, and facilitates the obtaining of amplitude values with high accuracy.

The following detailed description is made of a method and an apparatus for controlling a washing machine and a washing machine provided by the present application with reference to the specific embodiments.
Referring to fig. 3, fig. 3 schematically illustrates a flow of steps of a control method of a washing machine provided in an embodiment of the present application. The washing machine control method may mainly include steps S301 to S303 as follows.
Step S301, acquiring an amplitude value of the inner drum of the washing machine.
And acquiring the amplitude value of the inner barrel of the washing machine, so that the corresponding eccentricity of the inner barrel of the washing machine can be conveniently determined according to the amplitude value of the inner barrel of the washing machine.
Step S302, when the amplitude value of the inner drum of the washing machine is smaller than a preset threshold, determining the eccentricity of the inner drum of the washing machine according to the amplitude value of the inner drum of the washing machine.
When the amplitude value of the inner drum of the washing machine is smaller than the preset threshold value, the inner drum of the washing machine is not considered to collide with other structures of the washing machine, and the eccentricity of the inner drum of the washing machine is determined under the condition that the inner drum of the washing machine does not collide, so that the condition that the inner drum of the washing machine collides with other structures can be avoided. The preset threshold is preset and can be considered as the limit amplitude when the inner drum of the washing machine and the box body of the washing machine just collide with each other.
And step S303, starting the washing machine according to the eccentricity to enter a preset dewatering program corresponding to the eccentricity.
Different dewatering programs are preset according to different eccentricity, for example, when the eccentricity is relatively large, the dewatering programs with relatively strong dewatering intensity are corresponding. If the eccentricity is smaller, the corresponding dehydration program has weaker dehydration strength. In practical application, a person skilled in the art can set the dehydration procedure according to actual needs.
Therefore, by acquiring the amplitude value of the inner barrel of the washing machine, when the amplitude value of the inner barrel of the washing machine is smaller than a preset threshold value, the eccentricity of the inner barrel of the washing machine is determined according to the amplitude value of the inner barrel of the washing machine, and the washing machine is started to enter a preset dehydration program corresponding to the eccentricity according to the eccentricity. When the amplitude value of the inner drum of the washing machine is smaller than the preset threshold value, the critical state that the drum of the washing machine collides with other structures is not considered, and in the current state, the proper eccentric amount is determined, so that the dehydration program corresponding to the eccentric amount is started, the washing machine drum can be prevented from colliding with other structures, and meanwhile, the dehydration program can be started normally, and the dehydration purpose is achieved.
Optionally, when the dewatering process is executed, drainage is first performed, after the drainage time is completed, the motor starts to execute the dewatering process, the acceleration sensor starts to acquire an acceleration signal at the moment, and the acceleration signal is stopped being acquired after the dewatering is completed. The system sets a filtering threshold of 1Hz to exclude interference factors.
In one embodiment of the present application, referring to fig. 4, fig. 4 schematically illustrates a flow of steps of a washing machine control method provided in another embodiment of the present application. The washing machine control method may further include steps S401 to S402 as follows.
Step S401, when the preset dehydration program is operated, detecting the amplitude value of the corresponding washing machine inner cylinder at the highest dehydration rotating speed.
The impeller washing machine is not provided with a safety switch any more, only two acceleration sensors are arranged, the motion low-frequency limit value of the barrel module can be set, and whether the barrel module is started or not is controlled by calling an eccentricity-amplitude quantity corresponding table. In addition, the maximum rotation speed value, for example, 600rpm or 700rpm, can be determined according to the measured eccentricity, and after the maximum dehydration rotation speed is reached, the fine adjustment of the dehydration rotation speed is performed again according to the amplitude of the barrel module.
In the process of operating the preset dehydration program, because the preset dehydration program is influenced by other factors in the operation process, certain deviation exists between the amplitude value of the current inner drum of the washing machine and the amplitude value corresponding to the ideal state. In order to prevent the inner tub of the washing machine from colliding with other structures of the washing machine during the operation of the preset dehydration program, it is necessary to detect the amplitude value of the inner tub of the washing machine corresponding to the highest dehydration rotation speed, and to prevent the inner tub of the washing machine from colliding with other structures of the washing machine by grasping the amplitude value corresponding to the highest dehydration rotation speed.
Step S402, when the amplitude value of the inner drum of the washing machine is larger than a first preset amplitude value, the dehydration rotating speed of the inner drum of the washing machine is adjusted, so that the amplitude value of the inner drum of the washing machine is smaller than or equal to the first preset amplitude value.
When the amplitude value of washing machine inner tube is greater than preset amplitude value, then think that washing machine inner tube has the risk of collision, in order to prevent that washing machine inner tube from colliding, consequently, need adjust the dehydration rotational speed of dehydration procedure to reduce the amplitude value of washing machine inner tube, so that the amplitude value of washing machine inner tube is less than or equal to first preset amplitude value, in order to play the effect of protection washing machine inner tube, in addition, also prevent to collide the noise that produces, make user experience effect not good.
Like this, when the dehydration procedure is predetermine in the operation, detect the amplitude value of the washing machine inner tube that corresponds under the highest dehydration rotational speed, when the amplitude value of washing machine inner tube is greater than first preset amplitude value, adjust the dehydration rotational speed of washing machine inner tube to reduce the amplitude value of washing machine inner tube, prevent that the washing machine inner tube from colliding, thereby the noise that produces makes the not good problem of user experience effect take place.
In one embodiment of the present application, referring to fig. 5, fig. 5 schematically illustrates a flow of steps for determining the eccentricity of the drum of the washing machine according to the amplitude value of the drum in one embodiment of the present application. When the amplitude value of the inner drum of the washing machine is smaller than the preset threshold, the eccentricity of the inner drum of the washing machine is determined according to the amplitude value of the inner drum of the washing machine, and the method mainly comprises the following steps S501 to S502.
Step S501, acquiring a mapping relation between the amplitude value and the eccentricity.
And obtaining the corresponding eccentricity value according to the amplitude value obtained by measurement through the mapping relation between the amplitude value and the eccentricity value. Wherein, the amplitude value and the eccentricity are in one-to-one correspondence.
Step S502, according to the mapping relation between the amplitude value and the eccentricity, the eccentricity corresponding to the amplitude value of the inner drum of the washing machine is determined.
And after the mapping relation between the amplitude value and the eccentricity is obtained, displaying the mapping relation in a form of a table, storing the table in advance, and determining the corresponding eccentricity according to the amplitude value of the inner drum of the washing machine by searching the corresponding table of the amplitude value and the eccentricity.
Therefore, the mapping relation between the amplitude value and the eccentricity is obtained and stored in advance in a table form, so that the search is convenient and simple.
In an embodiment of the present application, referring to fig. 6, fig. 6 schematically shows a flow of steps for obtaining a mapping relationship between an amplitude value and an eccentricity amount in an embodiment of the present application. The obtaining of the mapping relationship between the amplitude value and the eccentricity amount may mainly include steps S601 to S604 as follows.
Step S601, setting an initial eccentricity and measuring an inner cylinder amplitude value corresponding to the initial eccentricity.
Generally, the initial eccentricity is set to 10% of the full load, for example, the initial eccentricity of a washing machine capable of carrying 9 kg is set to 900g, the initial eccentricity of a washing machine capable of carrying 10 kg is set to 1kg, that is, the eccentricity is put into the test module, and the inner cylinder amplitude value corresponding to the initial eccentricity is measured after the eccentricity is put.
Step S602, determining a plurality of intermediate eccentric quantities based on the initial eccentric quantity, wherein the intermediate eccentric quantities have different values, the intermediate eccentric quantities are greater than the initial eccentric quantity and less than the power-off eccentric quantity, and the amplitude value corresponding to the power-off eccentric quantity is a second preset amplitude value.
For the setting of the intermediate eccentricity amount, the eccentricity may be gradually increased on the basis of the initial eccentricity amount, wherein the eccentricity may be gradually increased in a manner of equal magnitude, for example, the eccentricity may be gradually increased by taking the maximum eccentricity amount of 5% as the magnitude, so that a plurality of eccentricity amounts are obtained. Of course, for the setting of the middle eccentric amount, on the basis of the initial eccentric amount, the eccentric amount may not be gradually increased in an equal amplitude manner, for example, the amplitude of the initial increase is larger, and the amplitude of the subsequent increase is gradually decreased, which is beneficial to accurately controlling the magnitude of the increased eccentric amount so as to obtain a more accurate amplitude value. When the eccentricity amount is gradually increased based on the basis of the initial eccentricity amount, the deenergized eccentricity amount may be determined when the eccentricity is added up to the allowable maximum eccentricity amount. It should be noted that the inner tub of the washing machine does not collide with other structures in the case of the maximum eccentricity.
Step S603, an inner cylinder amplitude value corresponding to each intermediate eccentricity is measured.
And on the basis of the initial eccentricity, gradually increasing the eccentricity to obtain a plurality of eccentricities, and measuring inner cylinder amplitude values corresponding to the eccentricities.
And step S604, obtaining a mapping relation between the amplitude value and the eccentricity according to the initial eccentricity, each intermediate eccentricity, the power-off eccentricity, the inner cylinder amplitude value corresponding to the initial eccentricity, the inner cylinder amplitude value corresponding to each intermediate eccentricity and the second preset amplitude value corresponding to the power-off eccentricity.
Therefore, eccentricity is gradually increased on the basis of the initial eccentricity to obtain a plurality of eccentricities, and then inner cylinder amplitude values corresponding to the eccentricities are measured, so that the mapping relation between the amplitude values and the eccentricities is conveniently established.
In one embodiment of the present application, the ratio between the initial eccentricity and the maximum load bearing capacity of the washing machine drum is 5% to 30%. That is, the initial eccentricity is generally set to 5% to 30% of the maximum load of the inner tub of the washing machine, for example, when the maximum load of the washing machine is W, the initial eccentricity may be set to W × 5%, or W × 10%, or W × 15%, or W × 20%, or W × 25%, or W × 30%, etc. When the initial eccentricity is 10% of the maximum load-bearing capacity of the inner drum of the washing machine, for example, the initial eccentricity of the washing machine capable of bearing 9 kg is 900g, and the initial eccentricity of the washing machine capable of bearing 10 kg is 1kg, which is beneficial to constructing the mapping relation between the amplitude value and the eccentricity in a proper range.
In one embodiment of the present application, the second preset amplitude value is a minimum gap value between the washing machine cylinder and each side wall of the box body, wherein the second preset amplitude value is smaller than or equal to the first preset amplitude value.
In order to prevent the inner tub of the washing machine from colliding with other structures, therefore, it is necessary to determine the maximum allowable eccentricity amount, and the magnitude of the maximum eccentricity amount is determined by the second preset amplitude value.
And the second preset amplitude value is 0.9 Min (a gap between the washing machine cylinder and each side wall of the box body).
Like this, through confirming the minimum value of clearance value between washing machine barrel and each lateral wall of box for predetermined amplitude calculation value to prevent washing machine's inner tube and other lateral wall structures from colliding, with improvement user experience.
When the measured inner cylinder amplitude value is consistent with a preset amplitude calculation value, determining the eccentric quantity corresponding to the inner cylinder amplitude value as the power-off eccentric quantity; and when the measured inner cylinder amplitude value is inconsistent with the preset amplitude calculation value, adjusting the eccentric quantity corresponding to the inner cylinder amplitude value to enable the inner cylinder amplitude value to be consistent with the preset amplitude value, and determining the finally adjusted eccentric quantity as the power-off eccentric quantity.
For facilitating understanding of the technical solution of the present application, referring to fig. 7, fig. 7 schematically shows a mapping table of an amplitude value and an eccentricity provided in an embodiment of the present application. Wherein the initial eccentricity is set to M0.05Obtaining corresponding amplitude value A1, gradually increasing the eccentricity based on the initial eccentricity, and setting the next eccentricity as M0.10，Obtaining a corresponding amplitude value A2, then increasing eccentricity by constant amplitude, and measuring to obtain a corresponding amplitude value until reaching the maximum eccentricity, namely MWhen the power is cut off, the power supply is cut off,obtaining corresponding amplitude value AmaxSo as to establish a mapping relation table of the obtained amplitude value and the eccentricity.
Therefore, the maximum eccentric amount is determined, so that the collision between the inner barrel of the washing machine and other structures is prevented, and the user experience is improved.
In one embodiment of the present application, the method further comprises:
and when the amplitude of the inner drum of the washing machine is greater than or equal to a preset threshold value, performing power-off operation on the washing machine and injecting liquid into the inner drum of the washing machine. In this way, subsequent execution of the dewatering process is facilitated.
It should be noted that although the various steps of the methods in this application are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the shown steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
