Background
The dehydration of the washing machine refers to the separation of water from the clothes in the washing machine by using centrifugal force, and the dehydration rotating speed directly influences the dehydration effect of the washing machine.
At present, the method for setting the dehydration rotation speed of the drum washing machine is mainly set according to the comparison result between the actual eccentric load capacity of the drum washing machine and the eccentric load capacity set value, wherein each limit value of the eccentric load capacity set value is a numerical value set by performing a no-load test on the drum washing machine in advance, the minimum limit value mainly depends on the maximum dehydration rotation speed of the drum washing machine, and the maximum limit value mainly depends on the maximum eccentric load capacity of the drum washing machine capable of normally operating.
However, when the user selects the non-highest speed gear to be dehydrated, it may take a long time to adjust the eccentric load amount setting value from the minimum limit value to the limit value that satisfies the current load. Meanwhile, under the condition that the actual eccentric load quantity of the drum washing machine is detected by utilizing the fluctuation of the rotating speed of the motor, the fluctuation change of the rotating speed of the motor is smaller when the washing load quantity is larger, so that the detection result of the eccentric load quantity is influenced, namely, the difference between the detection value and the actual value of the eccentric load quantity is increased, and the difference is further increased along with the increase of the eccentric load quantity. The difference between the detected value and the actual value of the eccentric load amount may cause a certain noise of the drum washing machine, and particularly, a large noise may be generated when the rotation speed of the drum washing machine is high.

Compared with the closest prior art, the technical scheme at least has the following beneficial effects:
the invention provides a dehydration rotating speed control method of washing equipment, which mainly comprises the following steps: acquiring a load gear corresponding to the washing load weight according to the corresponding relation between a preset load gear and the preset load weight, judging whether a dehydration rotating speed gear input by a user is a highest dehydration rotating speed gear, acquiring an eccentric load limit value of the washing equipment according to the judgment result and the load gear corresponding to the washing load weight, comparing the actual eccentric load value of the washing equipment with the eccentric load limit value, and controlling the dehydration rotating speed of the washing equipment according to the comparison result.
Specifically, when the dehydration rotation speed gear input by the user is the highest dehydration rotation speed gear, the corresponding first eccentric load amount limit value is acquired based on the corresponding relation between the preset load gear and the preset first eccentric load amount limit value and according to the load gear corresponding to the washing load weight, and then the first eccentric load amount limit value is set as the eccentric load amount limit value of the washing device. The first eccentric load amount limiting value comprises a plurality of first limiting values, the minimum first limiting value in the first eccentric load amount limiting values corresponding to each load gear is equal, and the non-minimum first limiting value in the first eccentric load amount limiting values corresponding to each load gear depends on the corresponding load gear. Meanwhile, the invention can also control the washing equipment to execute the load shaking operation within the preset time length when the actual eccentric load is more than or equal to the current limit value, so as to reduce the actual eccentric load of the washing equipment. The preset duration corresponding to the high load gear may be longer than the preset duration corresponding to the low load gear.
For example, if the load gear of the washing load is low when the user selects the non-maximum dehydration rotation speed gear, the eccentric load amount limit value with the larger minimum limit value is used, so that the possibility that the actual eccentric load amount of the washing equipment is greater than or equal to the minimum limit value can be reduced, the possibility that the washing equipment is controlled to perform the load shaking operation when being compared with the minimum limit value is reduced, and the dehydration time is prevented from being increased due to the performance of the load shaking operation.
If the load gear of the washing load is higher when the user selects the gear with the non-highest dehydration rotation speed, the detection value of the eccentric load amount is often smaller than the true value (under the condition that the actual eccentric load amount of the drum washing machine is detected by utilizing the fluctuation of the rotation speed of the motor, the fluctuation change of the rotation speed of the motor is smaller when the washing load amount is larger, the detection result of the eccentric load amount is influenced, namely the difference between the detection value of the eccentric load amount and the true value is increased, and the difference is further increased along with the increase of the eccentric load amount), and the error is reduced by using the limit value of the eccentric load amount with the smaller minimum limit value.
Further, when the dehydration rotation speed gear input by the user is not the highest dehydration rotation speed gear, acquiring a corresponding second eccentric load amount limit value according to a load gear corresponding to the washing load weight based on a corresponding relation between a preset load gear and a preset second eccentric load amount limit value, and then setting the second eccentric load amount limit value as the eccentric load amount limit value of the washing device. Wherein the second eccentric load amount limit comprises a plurality of second limit values, the largest second limit value of the second eccentric load amount limit values corresponding to each load gear is equal, and the non-largest second limit value of the second eccentric load amount limit values corresponding to each load gear depends on the corresponding load gear.
For example, when the user selects the highest dehydration rotation speed gear, if the load gear of the washing load is low, the difference between the detected value and the real value of the eccentric load amount when the rotation speed is high will cause the washing device to generate large noise, and the eccentric load amount limit value with a large maximum limit value is used to reduce the error, and if the load gear of the washing load is high, the eccentric load amount limit value with a small maximum limit value is used to reduce the dehydration noise.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The following describes a method for controlling the spin-drying speed of a washing machine according to the present invention with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 illustrates the main steps of a dehydration rotation speed control method of a washing apparatus in the present embodiment. As shown in fig. 1, the dewatering rotation speed of the washing apparatus can be controlled according to the following steps in this embodiment:
step S101: the weight of the wash load within the washing apparatus is detected.
Alternatively, the present embodiment may detect the weight of the washing load (e.g., clothes) after washing with the washing water by using a weighing device preset in the washing apparatus (e.g., washing machine or laundry dryer).
Step S102: and acquiring a load gear corresponding to the washing load weight according to the corresponding relation between the preset load gear and the preset load weight.
Specifically, the corresponding relationship between the preset load gear and the preset load weight in the present embodiment depends on the load capacity of the washing apparatus. Optionally, in this embodiment, 3 load gears may be divided according to the load capacity of the washing device (for example, load gears 1, 2 and 3 and the load weights corresponding to load gears 1, 2 and 3 sequentially increase).
Step S103: and judging whether the dehydration rotating speed gear input by the user is the highest dehydration rotating speed gear. Specifically, if the dehydration rotation speed gear input by the user is the highest dehydration rotation speed gear, the step S104 is executed; if the dehydration rotation speed gear input by the user is not the highest dehydration rotation speed gear, go to step S106.
Step S104: and acquiring a corresponding first eccentric load amount limit value according to a load gear corresponding to the washing load weight based on the corresponding relation between a preset load gear and a preset first eccentric load amount limit value. The first eccentric load amount limiting value may include first limiting values corresponding to a plurality of preset rotation speed gears respectively, the first limiting values corresponding to the highest rotation speed gear in each load gear are all equal, and the first limiting value of each non-highest rotation speed gear in the high load gear is smaller than the first limiting value of the corresponding non-highest rotation speed gear in the low load gear.
For example, the load range of the washing apparatus includes load range 1, load range 2 and load range 3 and the load weights corresponding to load range 1, load range 2 and load range 3 sequentially increase, and the first eccentric load amount limit values corresponding to load range 1, load range 2 and load range 3 are L1, L2 and L3, respectively, wherein the first eccentric load amount limit value L1 includes a first limit value L11, a first limit value L12 and a first limit value L13 and L11< L12< L13, the first eccentric load amount limit value L2 includes a first limit value L21, a first limit value L22 and a first limit value L23 and L21< L22< L23, and the first eccentric load amount limit value L3 includes a first limit value L31, a first limit value L32 and a first limit value L33 and L31< L32< L33.
Wherein, the first limit value L11, the first limit value L21 and the first limit value L31 are all limit values corresponding to the rotational speed gear 1 and L11= L21= L31, the first limit value L12, the first limit value L22 and the first limit value L32 are all limit values corresponding to the rotational speed gear 2 and L12 > L22 > L32, the first limit value L13, the first limit value L23 and the first limit value L33 are all limit values corresponding to the rotational speed gear 3 and L13 > L23 > L33, wherein the rotational speeds corresponding to the rotational speed gear 1, the rotational speed gear 2 and the rotational speed gear 3 are sequentially reduced.
Step S105: the first eccentric load amount limit is set as an eccentric load amount limit of the washing apparatus. Specifically, in the present embodiment, the first eccentric load amount limit is set as the eccentric load amount limit of the washing apparatus, and then the process goes to step S108.
Step S106: and acquiring a corresponding second eccentric load amount limit value according to the load gear corresponding to the washing load weight based on the corresponding relation between the preset load gear and the preset second eccentric load amount limit value. The second eccentric load limiting value comprises second limiting values corresponding to a plurality of preset rotating speed gears respectively, the second limiting values corresponding to the lowest rotating speed gear in each load gear are equal, and the second limiting value of each non-lowest rotating speed gear in the high load gear is smaller than the second limiting value of the corresponding non-lowest rotating speed gear in the low load gear respectively.
For example, the load range of the washing apparatus includes load range 1, load range 2 and load range 3 and the load weights corresponding to the load range 1, load range 2 and load range 3 sequentially increase, and the second eccentric load amount limit values corresponding to the load range 1, load range 2 and load range 3 are L4, L5 and L6, respectively, wherein the second eccentric load amount limit value L4 includes a second limit value L41, a second limit value L42 and a second limit value L43 and L41< L42< L43, the second eccentric load amount limit value L5 includes a second limit value L51, a second limit value L52 and a second limit value L53 and L51< L52< L53, and the second eccentric load amount limit value L6 includes a second limit value L61, a second limit value L62 and a second limit value L63 and L61< L62< L63.
Wherein, second limit value L41, second limit value L51 and second limit value L61 are all limit values corresponding to speed gear 1 and L41 > L51 > L61, second limit value L42, second limit value L52 and second limit value L62 are all limit values corresponding to speed gear 2 and L42 > L52 > L62, and second limit value L43, second limit value L53 and second limit value L63 are all limit values corresponding to speed gear 3 and L43= L53= L63, wherein the rotation speeds corresponding to speed gear 1, speed gear 2 and speed gear 3 are sequentially reduced.
Step S107: the second eccentric load amount limit is set as an eccentric load amount limit of the washing apparatus. Specifically, in the present embodiment, the second eccentric load amount limit is set as the eccentric load amount limit of the washing apparatus, and then the process goes to step S108.
Step S108: comparing the actual eccentric load amount of the washing device with the eccentric load amount limit value and controlling the dehydrating rotation speed of the washing device according to the comparison result.
Specifically, the dewatering rotation speed of the washing apparatus may be controlled according to the comparison result of the actual eccentric load amount and the eccentric load amount limit value and according to the following steps:
step S1081: judging whether the actual eccentric load is smaller than the corresponding limit value according to the sequence of the limit values from small to large in the eccentric load limit values: if the actual eccentric load amount is greater than or equal to the current limit value, the process proceeds to step S1082, and if the actual eccentric load amount is less than the current limit value, the process proceeds to step S1083. Wherein the limit value is a first limit value when the eccentric load amount limit value is a first eccentric load amount limit value; the limit is a second limit when the eccentric load amount limit is a second eccentric load amount limit.
Step S1082: controlling the washing equipment to execute load shaking operation within a preset time length and judging whether the actual eccentric load of the washing equipment is smaller than the current limit value again: if the actual amount of eccentric load is equal to or greater than the current limit value, the process proceeds to step S1084, and if the actual amount of eccentric load is less than the current limit value, the process proceeds to step S1083.
The preset time period in this embodiment depends on the load gear corresponding to the weight of the washing load, i.e. the preset time periods corresponding to different load gears may be different. For example, the preset duration corresponding to the high load gear may be longer than the preset duration corresponding to the low load gear. Optionally, the preset durations corresponding to different limiting values in the load eccentricity limiting values corresponding to the same load gear may also be different. For example, the limit value corresponding to the high speed gear may be smaller than the limit value corresponding to the low speed gear, and thus, the preset duration of the limit value corresponding to the high speed gear may be greater than the preset duration of the limit value corresponding to the low speed gear, i.e., the washing apparatus is controlled to perform the load shaking operation for a longer time to maximally reduce the actual eccentric load amount of the washing apparatus in the high speed gear, and the washing apparatus is controlled to perform the load shaking operation for a shorter time to avoid an increase in the dehydration time due to the performance of the load shaking operation in the low speed gear.
Step S1083: stopping comparing the actual eccentric load amount of the washing device with the eccentric load amount limit value and controlling the dehydrating rotation speed of the washing device according to the current limit value.
Specifically, the present embodiment may control the spin-drying speed of the washing apparatus according to the current limit value and according to the following steps:
step 1: and acquiring a rotating speed gear corresponding to the current limiting value based on the corresponding relation between the preset limiting value and the preset rotating speed gear.
For example, when the eccentric load amount limit value L1 includes a limit value L11, a limit value L12, and a limit value L13, and the rotational speed gear includes a rotational speed 1, a rotational speed 2, and a rotational speed 3, the correspondence relationship of each limit value to each rotational speed gear may be: the rotational speed gear corresponding to the numerical range (0 L11) is rotational speed 1, the rotational speed gear corresponding to the numerical range [ L11L 12) is rotational speed 2, and the rotational speed gear corresponding to the numerical range [ L12L 13) is rotational speed 3. Therefore, the gear is speed 1 if the current limit falls within the numerical range (0L 11), speed 2 if the current limit falls within the numerical range [ L11L 12), and speed 3 if the current limit falls within the numerical range [ L12L 13).
And 2, step: and controlling the dehydration rotating speed of the washing equipment according to the rotating speed gear, namely controlling the washing equipment to rotate according to the rotating speed specified by the rotating speed gear.
Step S1084: and continuously judging whether the actual eccentric load amount of the washing equipment is less than the next limit value.
In this embodiment, if the actual eccentric load amount is equal to or greater than the maximum limit value after sequentially comparing all the limit values of the eccentric load amount limit values, the dehydration rotation speed control is stopped and an alarm is given.
Further, in an alternative embodiment provided by the present invention, the dehydration rotation speed control method shown in fig. 1 may further perform the following steps before performing step S108:
step 1: judging whether the actual eccentric load is smaller than the limit value corresponding to the highest rotating speed gear in the eccentric load limit value: and (3) if the actual eccentric load is smaller than the limit value corresponding to the highest rotating speed gear, turning to step (3), and if the actual eccentric load is larger than or equal to the limit value corresponding to the highest rotating speed gear, turning to step (2).
Step 2: the washing apparatus is controlled to perform a load shaking operation so as to reduce an actual eccentric load amount of the washing apparatus.
And step 3: the washing apparatus is controlled not to perform a load shaking operation.
The method for controlling the spin-drying speed of the washing apparatus according to the present invention will be further described with reference to fig. 2 to 4. Wherein fig. 2 illustrates a dehydration rotation speed control curve of a washing apparatus in the related art, fig. 3 illustrates a dehydration rotation speed control curve of a washing apparatus when a user selects a non-highest rotation speed gear in the present embodiment, and fig. 4 illustrates a dehydration rotation speed control curve of a washing apparatus when a user selects a highest rotation speed gear in the present embodiment.
The eccentric load amount limit in the prior art is fixed and does not change with the weight of the washing load and/or the rotational speed gear set by the user. As shown in fig. 2, when the washing apparatus enters the dehydrating operation, the actual eccentric load amount Lr of the washing apparatus is first compared with the limit value L0,
when Lr < L0, setting the dehydration rotating speed of the washing equipment as rotating speed 1;
when Lr is larger than or equal to L0, judging whether Lr is smaller than L0 within T0:
if Lr < L0, setting the dehydration rotating speed of the washing device as rotating speed 1,
if Lr is larger than or equal to L0, the compared limiting value linearly rises to a maximum limiting value Lt, and within the time from T0 to T1, if Lr is smaller than L0, the dehydration rotating speed of the washing equipment is set to be 1, if L0 is larger than or equal to Lr and smaller than L1, the dehydration rotating speed of the washing equipment is set to be 2, and if L1 is larger than or equal to Lr and smaller than Lt, the dehydration rotating speed of the washing equipment is set to be 3. Wherein L0< L1< Lt.
The dehydration rotating speed control method provided by the invention can obtain the corresponding eccentric load limit value according to the weight of the washing load and/or the rotating speed gear set by a user, so that the rapid dehydration and the low-noise dehydration can be realized when the washing loads with different weights are dehydrated.
Referring to fig. 3, as shown in fig. 3, in the present embodiment, the weight of the washing load is divided into 3 load steps (load amount 1, load amount 2, and load amount 3, and the load weights corresponding to the load amount 1, the load amount 2, and the load amount 3 are sequentially increased), each load step corresponds to a first eccentric load amount limit value, and the maximum limit value included in each first eccentric load amount limit value is Lt. The minimum limit value in the first eccentric load capacity limit value corresponding to the load amount 1 is L1, the minimum limit value in the first eccentric load capacity limit value corresponding to the load amount 2 is L2, and the minimum limit value in the first eccentric load capacity limit value corresponding to the load amount 3 is L3.
For example, when the washing device enters the dewatering operation, if the load gear corresponding to the current washing load weight is load 1 according to the corresponding relation between the load weight and the load gear, the actual eccentric load Lr of the washing device is compared with the limit value L1,
setting the dehydration rotating speed of the washing equipment as the rotating speed 1 when Lr is less than L1;
when Lr is larger than or equal to L1, controlling the washing equipment to execute load shaking operation and judging whether Lr is smaller than L1 in T0 time:
if Lr < L1, setting the dehydration rotation speed of the washing device as rotation speed 1,
if Lr is larger than or equal to L1, the compared limit value linearly rises to a maximum limit value Lt1, and within the time from T0 to T1, if Lr < L1, the dehydration rotating speed of the washing equipment is set to be 1, if L1 is larger than or equal to Lr < L11, the dehydration rotating speed of the washing equipment is set to be 2, and if L11 is larger than or equal to Lr < Lt, the dehydration rotating speed of the washing equipment is set to be 3. Where L1< L11< Lt (not shown in fig. 3).
For another example, if the load gear corresponding to the current washing load weight is load 2 according to the corresponding relationship between the load weight and the load gear when the washing device enters the dewatering operation, the actual eccentric load amount Lr of the washing device is compared with the limit value L2,
when Lr is less than L2, setting the dehydration rotating speed of the washing equipment as a rotating speed 1;
when Lr is larger than or equal to L2, controlling the washing equipment to execute load shaking operation and judging whether Lr is smaller than L2 in T0 time:
if Lr < L2, the dehydration rotation speed of the washing apparatus is set to a rotation speed of 1,
if Lr is larger than or equal to L2, the compared limit value linearly rises to a maximum limit value Lt2, and within the time from T0 to T1, if Lr < L2, the dehydration rotating speed of the washing equipment is set as rotating speed 1, if L2 is larger than or equal to Lr < L21, the dehydration rotating speed of the washing equipment is set as rotating speed 2, and if L21 is larger than or equal to Lr < Lt, the dehydration rotating speed of the washing equipment is set as rotating speed 3. Wherein L2< L21< Lt (not shown in fig. 3).
With continuing reference to fig. 4, as shown in fig. 4, in the present embodiment, the weight of the washing load is divided into 3 load steps (load amount 1, load amount 2, and load amount 3, and the load weights corresponding to load amount 1, load amount 2, and load amount 3 are sequentially increased), each load step corresponds to a second eccentric load amount limit value, and the minimum limit value included in each second eccentric load amount limit value is L0. The maximum limit value of the second eccentric load capacity limit values corresponding to the load quantity 1 is Lt1, the maximum limit value of the second eccentric load capacity limit values corresponding to the load quantity 2 is Lt2, and the maximum limit value of the second eccentric load capacity limit values corresponding to the load quantity 3 is Lt3.
For example, when the washing device enters the dewatering operation, if the load gear corresponding to the current washing load weight is load 1 according to the corresponding relation between the load weight and the load gear, the actual eccentric load Lr of the washing device is compared with the limit value L0,
when Lr < L0, setting the dehydration rotating speed of the washing equipment as rotating speed 1;
