Description
Technical Field
The invention relates to the technical field of washing machine control, in particular to a dehydration rotating speed control method of washing equipment.
Background
The dehydration of the washing machine refers to the separation of water from the clothes in the washing machine by centrifugal force, and the dehydration speed directly affects 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 weight of the washing load is small or the washing load is liable to generate a large eccentric load at the time of dehydration, it is often required to take a long time to adjust from the minimum limit value to a limit value satisfying the current load.

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 dewatering rotation speed control method of the washing device provided by the invention is explained 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 spin-drying 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., laundry) after washing with the washing water by using a weighing device previously provided 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 gear 1, load gear 2, and load gear 3, and the load weights corresponding to load gear 1, load gear 2, and load gear 3 sequentially increase).
Step S103: and acquiring a corresponding eccentric load capacity limit value according to a load gear corresponding to the washing load weight based on the corresponding relation between the preset load gear and the preset eccentric load capacity limit value. The eccentric load amount limit value may include limit values corresponding to a plurality of unequal rotation speed gears that are preset, and the limit value of each rotation speed gear in the high load gear is smaller than the limit value of the corresponding 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, the 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 eccentric load amount limit value L1 includes a limit value L11, a limit value L12 and a limit value L13 and L11< L12< L13, the eccentric load amount limit value L2 includes a limit value L21, a limit value L22 and a limit value L23 and L21< L22< L23, the eccentric load amount limit value L3 includes a limit value L31, a limit value L32 and a limit value L33 and L31< L32< L33.
Wherein, limit value L11, limit value L21 and limit value L31 are all limit values corresponding to speed gear 1 and L11 > L21 > L31, limit value L12, limit value L22 and limit value L32 are all limit values corresponding to speed gear 2 and L12 > L22 > L32, limit value L13, limit value L23 and limit value L33 are all limit values corresponding to speed gear 3 and L13 > L23 > L33, wherein, the rotating speeds corresponding to speed gear 1, speed gear 2 and speed gear 3 are reduced in sequence.
Step S104: 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 S1041: 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 goes to step S1042, and if the actual eccentric load amount is less than the current limit value, the process goes to step S1043.
Step S1042: 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 eccentric load amount is greater than or equal to the current limit value, the process proceeds to step S1044, and if the actual eccentric load amount is less than the current limit value, the process proceeds to step S1043.
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 S1043: 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 rotational speed gear is rotational speed 1 if the current limit value falls within the numerical range (0L 11), rotational speed 2 if the current limit value falls within the numerical range [ L11L 12), and rotational speed 3 if the current limit value falls within the numerical range [ L12L 13).
And 2, step: and controlling the dewatering 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.
Further, in an alternative embodiment of the present invention, the spin speed of the washing apparatus may be controlled 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.
The corresponding relationship between the preset limiting value and the preset rotation speed gear in this embodiment is the same as the corresponding relationship between the preset limiting value and the preset rotation speed gear, and for brevity of description, no further description is given here.
And 2, step: judging whether a rotating speed gear set value input by a user is detected: if the detection is detected, the step 3 is carried out, and if the detection is not detected, the step 5 is carried out.
And step 3: judging whether the rotating speed gear is consistent with a set value of the rotating speed gear: and (5) if the rotating speed gear is not consistent with the set rotating speed gear, turning to the step (4), and if the rotating speed gear is consistent with the set rotating speed gear, turning to the step (5).
And 4, step 4: and selecting a lower rotating speed gear from the rotating speed gear and the rotating speed gear set value, and controlling the dehydration rotating speed of the washing equipment according to the lower rotating speed gear.
Suppose that: the eccentric load limit L1 includes a limit value L11, a limit value L12, and a limit value L13, the rotational speed gear includes a rotational speed 1, a rotational speed 2, and a rotational speed 3, and the corresponding relationship between each limit value and 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.
For example, if the actual eccentric load amount Lr < L11 of the washing apparatus, the corresponding rotational speed step is the rotational speed 1, and the rotational speed step setting value input by the user is the rotational speed 2, the actual eccentric load amount Lr satisfies the limit value of the rotational speed 2 because Lr < L12, the washing apparatus is controlled to perform the dehydrating operation according to the rotational speed 2.
If the actual eccentric load amount L12< Lr < L13 of the washing apparatus, the corresponding rotational speed range is the rotational speed 3, and the rotational speed range setting value input by the user is the rotational speed 2, the actual eccentric load amount Lr does not satisfy the limit value of the rotational speed 2 but only satisfies the limit value of the rotational speed 3 because Lr > L12, the washing apparatus is controlled to perform the dehydrating operation according to the rotational speed 3.
And if the actual eccentric load quantity Lr of the washing equipment is greater than L13, the washing equipment is controlled to stop executing the dehydration operation and give an alarm without considering the rotating speed gear set value input by the user.
And 5: and controlling the dewatering rotating speed of the washing equipment according to the rotating speed gear.
Step S1044: it is continuously judged whether the actual eccentric load amount of the washing apparatus 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 all the limit values of the eccentric load amount limit values are sequentially compared, the spinning speed control is stopped and an alarm is given.
Further, in an alternative embodiment provided by the present invention, the dewatering rotation speed control method shown in fig. 1 may further perform the following steps before performing step S104:
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 (4) if the actual eccentric load is smaller than the limit value corresponding to the highest rotating speed gear, turning to the 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 the 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 spinning speed of the washing machine according to the present invention will be further described with reference to fig. 2 and 3. Wherein, fig. 2 illustrates a dehydration rotation speed control curve of the washing apparatus in the related art, and fig. 3 illustrates a dehydration rotation speed control curve of the washing apparatus in the present embodiment.
The eccentric load limit in the prior art is fixed and does not vary with the weight of the wash load. 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, the dehydration rotation speed of the washing apparatus is set to a rotation speed of 1,
if Lr is larger than or equal to L0, the compared limit value linearly rises to a maximum limit value Lt, and within the time from T0 to T1, if Lr < L0, the dehydration rotating speed of the washing equipment is set to be 1, if L0 is larger than or equal to Lr < L1, the dehydration rotating speed of the washing equipment is set to be 2, and if L1 is larger than or equal to Lr < 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, so that the rapid dehydration and the low-noise dehydration can be realized when the washing loads with different weights are dehydrated. As shown in fig. 3, in the present embodiment, the weight of the washing load is divided into 3 load shift positions (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 shift position corresponds to an eccentric load amount limit value, and the minimum limit value (e.g., L1, L2 and L3, and L1> L2> L3) and the maximum limit value (e.g., lt1, lt2 and Lt3, and Lt1> Lt2> Lt 3) included in each eccentric load amount limit value are different. The minimum limit value of the eccentric load quantity limit values corresponding to the load quantity 1 is L1, the maximum limit value is Lt1, the minimum limit value of the eccentric load quantity limit values corresponding to the load quantity 2 is L2, the maximum limit value is Lt2, the minimum limit value of the eccentric load quantity limit values corresponding to the load quantity 3 is L3, and the maximum limit value 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 L1,
setting the dehydration rotating speed of the washing equipment as the rotating speed 1 when Lr is less than L1;
when Lr ≧ L1, the washing apparatus is controlled to perform a load shaking operation and it is determined whether Lr is smaller than L1 within T0:
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 < Lt1, the dehydration rotating speed of the washing equipment is set to be 3. Wherein L1< L11< Lt1 (not shown in fig. 3).
For another example, when the washing device enters the dewatering operation, 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, the actual eccentric load Lr of the washing device is compared with the limit value L2,
when Lr < 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 spinning 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 < Lt2, the dehydration rotating speed of the washing equipment is set as rotating speed 3. Wherein L2< L21< Lt2 (not shown in fig. 3).
