Detailed Description
In order that the above objects, features and advantages of the present invention will become more apparent, the following detailed description of the present invention is given in conjunction with the accompanying drawings and the detailed description of the invention, which are intended to illustrate, but not to limit the present invention.
Fig. 1 is a flowchart of a control method of a washing machine according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
s1, detecting the material and weight of the clothes to be washed;
s2, setting a dehydration rotation speed parameter before rinsing according to the material and/or weight of the clothes to be washed;
s3, setting rinsing parameters according to the material and weight of the clothes to be washed;
and S4, controlling the washing machine to perform dehydration and rinsing before rinsing according to the parameters.
Specifically, the operation process of the washing machine may include a main washing stage and a rinsing stage. In the main washing stage, the washing machine is controlled to sequentially perform water inlet, washing, water discharge and dehydration. And controlling the washing machine to enter a rinsing stage after the main washing stage is finished. And the parameters of each stage can be set according to the requirement.
According to an embodiment of the present invention, the type of the material of the laundry may be detected by detecting the water absorption rate of the laundry; the weight of the laundry is determined by fuzzy weighing.
According to another embodiment of the present invention, the type of the laundry may be detected by image recognition.
According to another embodiment of the invention, the material type of the clothes input by the user can be received through a human-computer interaction interface on the washing machine or a mobile terminal communicating with the washing machine, so as to obtain the material type of the clothes.
According to an embodiment of the present invention, the control device of the washing machine may set the spin-drying rotation speed parameter before rinsing according to the detected material and weight of the laundry.
According to another embodiment of the present invention, the control device of the washing machine may set the pre-rinsing spinning speed parameter only according to the detected material of the laundry or set the pre-rinsing spinning speed parameter only according to the detected weight of the laundry.
According to an embodiment of the present invention, the rinsing parameters are set according to the material and weight of the laundry.
According to one embodiment of the invention, the washing machine is controlled to perform dewatering and rinsing before rinsing according to the parameters.
According to one embodiment of the invention, the spin speed before rinsing is greater than or equal to the spin speed after rinsing of the washing machine.
In general, the spin speed of the washing machine before rinsing is the same as the spin speed after rinsing. According to an embodiment of the present invention, the spin speed before rinsing may be set to be greater than the spin speed after rinsing according to the detected material and weight of the laundry, so as to remove more bubbles.
According to one embodiment of the invention, the clothes material is set to be soft cloth, common cloth or hard cloth, the weight of the clothes is set to be M1, M2 or M3, wherein M1< M2< M3; the rinsing parameters comprise rinsing modes, rinsing time, rinsing water level and rinsing rotating speed corresponding to the materials and the weight of the clothes to be washed. Preferably, the rinsing mode comprises spray rinsing or water storage rinsing, or a combination of spray rinsing and water storage rinsing.
Judging whether the texture of the clothes is soft cloth, common cloth or hard cloth according to the water absorption rate of the clothes to be washed; according to the different percentage of the weight of the clothes to be washed in the maximum washing capacity of the washing machine, the weight of the clothes to be washed is judged to be small, medium or large, and respectively corresponds to M1, M2 and M3. Different combinations of clothes made of different materials and clothes with different weights can correspondingly generate different rinsing parameters, particularly different rinsing modes. For example, the rinsing of a large amount of hard cloth or a large amount of soft cloth adopts a combined mode of spray rinsing and water storage rinsing, and the water level of the water storage rinsing is improved by one grade compared with the washing water level; and a small amount of hard cloth or a small amount of soft cloth is only rinsed by storing water.
According to one embodiment of the invention, in the combined rinsing mode of the spray rinsing and the water storage rinsing, one or more times of dewatering are performed between the spray rinsing and the water storage rinsing. The rinsing time of the water accumulating rinsing is set to T1 when the laundry is hard cloth and has a weight of M3, to T2 when the laundry is soft cloth and has a weight of M3, and to T1> T2.
The time for spraying and rinsing can be determined according to the material and weight of the clothes to be washed, the spraying time is different, and the times for dewatering between the spraying and rinsing and the water storage rinsing are different. When the spray rinsing time is longer, only one time of dehydration is needed between the spray rinsing and the water storage rinsing; when the spray rinsing time is relatively short, the spray rinsing can be continued for a relatively short time after dehydration and then the dehydration is continued, so that the cycle can better remove the residual detergent. The foam generated by the same weight of clothes is removed more easily by the hard cloth than by the soft cloth, so that the hard cloth needs to be rinsed for a longer time than the soft cloth when the water is rinsed. Generally, the hard cloth is rinsed with water for 5 minutes, the normal cloth for 3-4 minutes, and the soft cloth for 2 minutes.
According to one embodiment of the invention, when the clothes to be washed is hard cloth and has the weight of M3, a combined rinsing mode of the spray rinsing and the water storage rinsing is selected, the spray rinsing adopts a continuous spray mode, and the dehydration rotating speed before rinsing is greater than the dehydration rotating speed after rinsing of the washing machine; preferably, the level of the impounded water rinse is increased by one step higher than the level of the wash water. When the clothes to be washed are soft cloth and the weight of the clothes is M3, selecting a combined rinsing mode of spray rinsing and water storage rinsing, wherein the spray rinsing adopts an intermittent spray mode, and the dehydration rotating speed before rinsing is equal to the dehydration rotating speed after rinsing of the washing machine; preferably, the level of the impounded water rinse is increased by one step higher than the level of the wash water.
Specifically, when the clothes to be washed are a large amount of hard cloth, the clothes are dehydrated at a high speed after the drainage is finished and before the rinsing is started, the dehydration rotating speed is greater than the dehydration rotating speed after the rinsing, and the clothes enter the rinsing stage after the dehydration of the stage is finished: firstly, continuously spraying and rinsing, then dehydrating, and then, feeding water to perform water storage rinsing, wherein the water level of the water storage rinsing is preferably improved by one grade compared with the washing water level. The continuous spraying mode means that the spraying time is relatively long, generally more than 1 minute and less than 2 minutes, for example, the continuous spraying time can be selected from 60 to 90 seconds. When the clothes to be washed are a large amount of soft cloth, dewatering before rinsing after draining, wherein the dewatering rotating speed is equal to the dewatering rotating speed after rinsing, and the clothes to be washed enter a rinsing stage after the dewatering at the stage: the method comprises the steps of intermittently spraying and rinsing, then feeding water to perform water storage rinsing, wherein the water level of the water storage rinsing is preferably higher than the washing water level by one step. The intermittent spraying mode is relative to the continuous spraying mode, and means that the spraying time is relatively short, generally, spraying is continued for 20 seconds or 15 seconds, then dewatering is carried out for 10 seconds, spraying is carried out for 20 seconds or 15 seconds, then dewatering is carried out for 10 seconds again, and the cycle is repeated for 3-4 times. And (5) entering a water storage rinsing stage, wherein the water storage rinsing time of the large quantity of hard cloth is longer than that of the large quantity of soft cloth. This is because the hard cloth has poor water absorption and the foam is less easily removed.
According to one embodiment of the invention, when the laundry is hard cloth or soft cloth and has a weight of M1, the water-storing rinsing mode is selected, and the spin speed before rinsing is equal to the spin speed after rinsing of the washing machine. Preferably, the level of the impounded water rinse is increased by one step or two steps from the washing water level.
Particularly, the clothes to be washed are a small amount of clothes, and the clothes are easy to adhere to the wall during dehydration, so that only a water storage rinsing mode is adopted during rinsing. When the clothes to be washed are hard cloth, the water level of the stored water rinsing is improved by two steps compared with the washing water level; when the clothes to be washed are soft cloth, the water level for water storage and rinsing can be the washing water level.
As described above, the spin-drying speed and the rinsing parameters before rinsing are selected according to the combination of the material and the weight of the clothes, so that the rinsing performance can be improved and the water resource can be saved to a certain extent.
Fig. 2 is a block schematic diagram of a control apparatus of a washing machine according to an embodiment of the present invention. As shown in fig. 2, the control apparatus includes an acquisition module and a control module.
The acquisition module is used for acquiring the material and weight of the clothes to be washed; and the control module is connected with the acquisition module and used for acquiring the dehydration rotating speed parameter and the rinsing parameter of the washing machine before rinsing according to the material and/or weight of the clothes to be washed and controlling the washing machine to perform dehydration and rinsing before rinsing according to the parameters.
According to an embodiment of the present invention, the obtaining module may detect a material type of the laundry by detecting a water absorption rate of the laundry, and determine a weight of the laundry by fuzzy weighing.
According to another embodiment of the present invention, the obtaining module may detect the type of the laundry material by means of image recognition.
According to another embodiment of the invention, the obtaining module may receive the clothes material type input by the user through a human-computer interface on the washing machine or a mobile terminal communicating with the washing machine, so as to obtain the material type of the clothes.
Specifically, the operation process of the washing machine may include a main washing stage and a rinsing stage. In the main washing stage, the control module controls the washing machine to sequentially perform water inlet, washing, water drainage and dehydration; the acquisition module detects the material and weight of the clothes to be washed. After the main washing stage is finished, the control module controls the washing machine to enter a rinsing stage. And in the dewatering stage before the washing machine enters rinsing, the control module acquires the dewatering rotating speed parameter of the washing machine before rinsing according to the material and/or weight of the clothes to be washed and controls the washing machine to dewater before rinsing according to the parameter. And (5) entering a rinsing stage, and controlling the washing machine to rinse by the control module according to the acquired parameters.
As described above, according to the control device of the washing machine provided by the embodiment of the present invention, the obtaining module obtains the material and weight of the laundry, and the control module obtains the dehydration rotation speed parameter and the rinsing parameter before rinsing, and controls the washing machine to perform dehydration and rinsing before rinsing according to the parameters. Therefore, the device controls the washing machine to select different dehydration rotating speeds and different rinsing parameters before rinsing through the combination of the material and the weight of the clothes to perform dehydration and rinsing before rinsing, and can improve the rinsing performance and save water resources to a certain extent.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the principle of the present invention, which should also be regarded as the protection scope of the present invention.
