In order to solve the problem that the rinsing effect of a washing machine in the prior art is greatly influenced by water pressure, the invention provides a washing method and a washing device of a washing device capable of adjusting water inlet parameters.
As shown in fig. 1, a washing method of a washing apparatus capable of adjusting a water inlet parameter includes a main washing method and a dehydration rinsing method, the dehydration rinsing method is performed after the main washing method is completed, and the dehydration rinsing method of the washing apparatus includes: selecting a dehydration rinsing program matched with the water inlet parameters according to the water inlet parameters; acquiring a dehydration rinsing instruction and entering a dehydration rinsing program, wherein the dehydration rinsing program comprises a plurality of sub-dehydration rinsing programs, and the plurality of sub-dehydration rinsing programs correspond to different preset parameter ranges; at least one sub-spin rinse program includes: controlling the water inlet adjusting piece 60 to be opened; at least one other sub-spin rinse program includes: controlling the drainage component 40 to be started, controlling the motor to rotate and controlling the spraying component 30 to spray water, wherein the bleaching times N, the bleaching duration T and the set value of the spraying flow Q in different sub-dewatering rinsing procedures are not completely equal; after the sub-dehydration rinsing process is performed, the final dehydration process is performed.
In the embodiment, different dewatering and rinsing procedures are adopted according to different water inlet parameters during dewatering and rinsing, wherein when the water inlet parameters do not meet requirements, the water inlet adjusting piece 60 can be started through the sub-dewatering and rinsing procedures to adjust the water inlet parameters, so that the water inlet parameters meet the parameter requirements of dewatering and rinsing, and the dewatering and rinsing effects are ensured; when the water inlet parameter meets the low requirement, a sub-dehydration rinsing program with the parameters of the bleaching times N, the bleaching duration T, the spraying flow Q and the like which are not completely the same can be selected according to the condition of the water inlet parameter, so that the dehydration rinsing effect is ensured, the water consumption is effectively reduced, and the waste of water resources is reduced. The washing method of the embodiment adopts spray rinsing to remove the rinsed clothes, namely, a conventional rinsing link is cancelled after washing, the clothes directly enter a dewatering program, the clothes are continuously or intermittently sprayed while being dewatered, water flow penetrates through the clothes by utilizing centrifugal force of high-speed rotation, and detergent residue is taken away, the same rinsing effect as the conventional rinsing is achieved, the clothes can be rinsed while being dewatered during rinsing, multiple times of rinsing in the original program are removed, the rinsing and dewatering time is reduced, and the rinsing effect is not influenced by water inlet parameters by matching with a mode of corresponding selection according to water inlet parameters, so that the rinsing effect under various water pressure conditions is ensured.
In the present embodiment, the water inlet parameter is taken as the water inlet pressure, accordingly, the standard spraying parameter for determining the water inlet pressure is taken as the standard spraying water pressure, and the water inlet adjusting member 60 employs a booster pump. Of course, the water inlet parameter may also be the water inlet flow rate or the water inlet flow velocity or a plurality of the water inlet parameters, correspondingly, the standard spraying parameter is the corresponding standard spraying flow rate or the standard spraying flow velocity, and the water inlet adjusting member 60 adopts a flowmeter or a flow velocity meter.
As shown in fig. 2 to 4, in the present embodiment, there are two limit values of the standard shower water pressure, which are a lower limit P1 and an upper limit P2, respectively. During the process of selecting the sub-dehydration rinsing program matched with the water pressure of the inlet water according to the water pressure of the inlet water, judging the relation between the water pressure P of the inlet water and the lower limit P1 of the standard spray water pressure; if the water inlet pressure P is less than the lower limit P1 of the standard spray water pressure, the water inlet pressure is too low to meet the spray requirement of the dehydration rinsing, so that a sub-dehydration rinsing program for controlling the booster pump to be started is selected, and the water inlet pressure of the sub-dehydration rinsing program is increased by the booster pump to meet the spray requirement of the dehydration rinsing; if the water inlet pressure P is greater than or equal to the lower limit P1 of the standard spray water pressure, the water inlet pressure meets the spray requirement of the dehydration rinsing, and therefore, the sub-dehydration rinsing program for controlling the water discharge assembly 40 to be started, the motor to be controlled to rotate and the spray assembly 30 to spray water is selected for the dehydration rinsing.
Specifically, the sub-dehydration rinsing program corresponding to the control of the opening of the drainage assembly 40, the rotation of the motor and the spraying of the spraying assembly 30 of the present embodiment includes a pre-dehydration stage and a rinsing stage which are sequentially executed. The pre-dehydration stage is used for discharging redundant water in the washing cavity before bleaching, and particularly, the drainage assembly 40 is controlled to be started in the operation process of the pre-dehydration stage; controlling the motor to rotate at a preset rotating speed VTTo dehydrate the laundry in the drum 20; calculating the dehydration time TTAfter the motor reaches the target speed, the rotating speed of the motor is controlled to be adjusted to VPSo that the rotation of the cylinder 20 meets the bleaching requirement, and then enters a bleaching stage; the rinsing stage is a stage mainly playing a role in spraying rinsing, and specifically, in the operation process of the rinsing stage, the cylinder body 20 keeps rotating and the spraying assembly 30 is controlled to spray water to a washing cavity of the washing device; calculating the time to spray T for spray assembly 30PAnd controlling the spray assembly 30 to be closed and stopping spraying. In the rinsing stage, the clothes in the drum 20 are rinsed and dehydrated at the same time, so that the rinsing and the dehydrating are simultaneously carried out, and the rinsing time is saved.
It should be noted that although the dewatering rinsing can be performed when the water inlet pressure P is equal to or higher than the lower limit P1 of the standard spray water pressure, when the water inlet pressure P is equal to or higher than the upper limit P2 of the standard spray water pressure, the laundry is more easily rinsed during the dewatering rinsing process than when the water inlet pressure is lower than P2, and therefore, a part of water resources are wasted. In order to solve the problem, according to the technical scheme, in the process of selecting the sub-dehydration rinsing program matched with the water pressure of the inlet water according to the water pressure of the inlet water, besides the relation between the water pressure P of the inlet water and the lower limit P1 of the standard spraying water pressure, the relation between the water pressure P of the inlet water and the upper limit P2 of the standard spraying water pressure is also judged, so that the specific parameters of the sub-dehydration rinsing program are correspondingly adjusted through the size relation between the water pressure P of the inlet water and the P2, and the condition of water resource waste caused by overhigh water pressure of the inlet water is reduced. Specifically, when the water inlet pressure P is greater than or equal to the lower limit P1 of the standard spray water pressure and is less than the upper limit P2 of the standard spray water pressure, the first sub-dehydration rinsing program is selected and entered; and when the water inlet pressure P is greater than or equal to the upper limit P2 of the standard spray water pressure, selecting and entering a second sub-dehydration rinsing program.
As shown in fig. 3 and 4, the processes between the first sub-dehydration rinsing process and the second sub-dehydration rinsing process are substantially the same, and the main difference therebetween is that the set values of the parameters, such as the number of times of bleaching N, the bleaching duration T, and the shower flow rate Q, are not completely the same. Specifically, the water inlet pressure of the second sub-dehydration rinsing program is higher, so that the rinsing time length T, the rinsing frequency N and the spraying flow Q corresponding to the second sub-dehydration rinsing program are reduced to a certain extent compared with the first sub-dehydration rinsing program. The bleaching duration T1, the bleaching times N1 and the spray flow Q1 of the first sub-dehydration rinsing program in the bleaching stage and the bleaching duration T2, the bleaching times N2 and the spray flow Q2 of the second sub-dehydration rinsing program in the bleaching stage satisfy:
n1 > N2; and/or
N1*TP1＞N2*TP2(ii) a And/or
QP1*N1*TP1＞QP2*N2*TP2Wherein Q isPIs the instantaneous flow of the spray. The bleaching duration T and the spray flow Q are the total amount of the whole bleaching stage, namely the total amount of N times of bleaching. Generally, QP1＝QP2. The specific values of the parameters can be set correspondingly according to actual conditions as long as the requirements are met.
Preferably, the rotational speed V of the motor is during the pre-dewatering phase operationTIs 500rpm to 1600rpm, preferably 800rpm to 1200 rpm; time of dehydration TTIs 1min-8min, preferably 3min-5 min. During the operation of the bleaching stage, the rotating speed V of the motorPFrom 100rpm to 1000rpm, preferably from 400rpm to 600 rpm; time of spraying TPIs 1min-8min, preferably3min-5 min. The bleaching times N are 1-3 times. The setting of the parameters can further ensure the effect of dehydration rinsing and save the time of dehydration rinsing. Of course, the above parameters may be changed accordingly as needed.
Preferably, the sub-dehydration rinsing procedure adopts a scheme that a pre-dehydration stage of high-speed pure dehydration and a bleaching stage of medium-speed spray dehydration are alternately carried out, the preferred scheme is that pure dehydration is carried out firstly and then spray dehydration is carried out, and the combination of one-time pure dehydration and one-time spray dehydration is recorded as the number of times of one-time bleaching.
Based on the above counting manner of the rinsing times, the sub-dehydration rinsing program in this embodiment further includes a comparison stage after the rinsing and dehydrating stage is completed, where the comparison stage is mainly used to control the times of rinsing and dehydrating, and in the comparison stage, each time the sub-dehydration rinsing program is completed, the rinsing times N is N +1, the times of the completed rinsing and dehydrating stage are called, and the times of the completed rinsing and dehydrating stage are equal to the times N of rinsing and dehydrating; the number of times of executing the completed bleaching stage and the preset number of times NPComparing; when the number of times of the bleaching stage is more than or equal to the preset number of times NPWhen the rinsing and dewatering are finished for the preset times, the final dewatering program is directly executed; when the number of times of the bleaching stage is less than the preset number of times NPThen, the number of times of rinsing and dewatering is insufficient, and the pre-dewatering stage and the rinsing stage are executed again until the number of times of the rinsing and dewatering stage is greater than or equal to the preset number of times NPAnd then the final dehydration procedure is executed. Generally, when the spin-rinsing process is finally completed, N ═ NPAccordingly, N1, N2 of the first and second sub-spin-rinse programs are equal to N, respectivelyP1、NP2。
It should be noted that as the number of times of bleaching increases, the time of the single pre-dewatering stage and bleaching stage may be shortened appropriately.
Since the water inlet parameters of the embodiment adopt the water inlet pressure, the water pressure of the user is divided into at least two gears, namely high and low. Preferably, the lower limit P1 of the standard spray water pressure is set to 0.3-1.0MPa, preferably 0.5-0.9 MPa. The upper limit P2 of the standard spray water pressure is set to 0.9-1.5MPa, preferably 1.0-1.4 MPa.
Of course, when the water inlet parameters adopt the water inlet flow or the water inlet flow speed, the corresponding standard spraying parameters are correspondingly set. Preferably, when the inflow water flow rate is adopted, the lower limit P1 of the standard spray flow rate is 5L/min, the upper limit P2 is 15L/min, so that the range of the standard spray flow rate is preferably set to be 5-15L/min, wherein the lower limit P1 is preferably 8L/min, and the upper limit P2 is preferably 13L/min, namely the standard spray flow rate is optimally 8-13L/min; when the inflow water flow rate is adopted, the range of the standard spraying flow rate can be correspondingly calculated according to the water supply pipe diameter and the flow range, the larger the water supply pipe diameter is, the smaller the sizes of P1 and P2 of the standard spraying flow rate are, and the smaller the water supply pipe diameter is, the larger the sizes of P1 and P2 of the standard spraying flow rate are.
In this embodiment, when the washing apparatus is started, the weighing apparatus is first controlled to weigh the clothes placed in the washing chamber, then the water inlet detection element 50 is controlled to obtain the water pressure of the inlet water, and then the main washing method is performed to perform the main washing, and after the main washing is completed, the above-mentioned dewatering rinsing method is performed. Of course, the process of controlling the water inlet pressure detecting element 50 to obtain the water inlet pressure may be performed after the main washing method is performed, as long as the process is performed before the spin rinsing method selects the spin rinsing program matched with the water inlet parameters according to the water inlet parameters.
