下面参考附图描述根据本发明实施例的洗衣机。图1是根据本发明实施例的洗衣机的结构框图，如图1所示，本发明实施例的洗衣机包括：内筒100、电机200、第一存储器300、速度传感器400、处理器500和控制器600。A washing machine in accordance with an embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a structural block diagram of a washing machine according to an embodiment of the present invention. As shown in FIG. 1, a washing machine according to an embodiment of the present invention includes an inner cylinder 100, a motor 200, a first memory 300, a speed sensor 400, a processor 500, and a controller. 600.
其中，电机200用于驱动内筒100转动。第一存储器300，存储有索引表，该索引表包括多个转速区间及对应的重量区间，其中，转速区间为内筒100启动后转动预定时间T的转速的区间。速度传感器400用于检测内筒100启动后转动预定时间T的转速。处理器500用于根据索引表确定该转速对应的重量区间，从而确定内筒100中的当前负载所落入的重量区间。同时控制器600根据当前负载的重量区间控制电机200驱动内100筒转动以进行相应方式的洗涤及脱水方式。The motor 200 is used to drive the inner cylinder 100 to rotate. The first memory 300 stores an index table including a plurality of rotation speed sections and corresponding weight sections, wherein the rotation speed section is a section of the rotation speed of the predetermined rotation time T after the inner cylinder 100 is started. The speed sensor 400 is for detecting the rotation speed of the predetermined rotation time T after the inner cylinder 100 is started. The processor 500 is configured to determine a weight interval corresponding to the rotation speed according to the index table, thereby determining a weight interval in which the current load in the inner cylinder 100 falls. At the same time, the controller 600 controls the motor 200 to drive the inner 100 cylinder rotation according to the weight interval of the current load to perform the corresponding manner of washing and dehydrating.
具体地，在本发明的一个实施例中，存储在第一存储器300的索引表的具体内容如下：Specifically, in one embodiment of the present invention, the specific contents of the index table stored in the first memory 300 are as follows:
假设该索引表中多个转速区间的数目为n，则第n个转速区间的转速为(RPM(n-1)，RPM(n))，对应的重量区间为(M(n-1)，M(n))。Assuming that the number of the plurality of rotational speed intervals in the index table is n, the rotational speed of the nth rotational speed interval is (RPM(n-1), RPM(n)), and the corresponding weight interval is (M(n-1), M(n)).
该索引表的建立过程如下：The establishment process of the index table is as follows:
(1)提供n种不同重量的负载分别置于内筒100中，控制电机200驱动内筒100转动预定时间T，预定时间T应小于内筒100空载时达到最高转速的时间；(1) providing n different weights of load respectively placed in the inner cylinder 100, and the control motor 200 drives the inner cylinder 100 to rotate for a predetermined time T, and the predetermined time T should be less than the time when the inner cylinder 100 reaches the maximum speed when it is idling;
(2)用速度传感器400检测内筒100启动后转动每种重量的负载预定时间T的转速，在同一时刻T，因负载重量不同所获取的转速将不同；(2) Using the speed sensor 400 to detect the rotation speed of the load of each weight for a predetermined time T after the inner cylinder 100 is started, at the same time T, the rotational speed obtained due to the difference in load weight will be different;
(3)同一时刻T，不同负载重量M(n)将对应不同的转速RPM(n)，处理器500对照不同负载重量区间(M(n-1)，M(n))将转速划分为n+1个转速区间。(3) At the same time T, the different load weights M(n) will correspond to different rotational speeds RPM(n), and the processor 500 divides the rotational speed into n according to different load weight intervals (M(n-1), M(n)). +1 speed range.
当检测到当前负载的转速rpm满足：RPM(n-1)≤rpm<RPM(n)时，则判定重量区间为(M(n-1)，M(n))。处理器500根据当前负载的转速确定其对应的重量区间，以便洗衣 机控制器600根据当前负载的重量区间进行相应方式的洗涤及脱水。When it is detected that the rotational speed rpm of the current load satisfies: RPM(n-1)≤rpm<RPM(n), it is determined that the weight interval is (M(n-1), M(n)). The processor 500 determines its corresponding weight interval according to the rotation speed of the current load, so as to wash the laundry. The machine controller 600 performs washing and dehydration in a corresponding manner according to the weight interval of the current load.
例如，在本发明的一个实施例中的16KG波轮洗衣机上，速度传感器设置在电机200上，按性能标准对负载经行5档区分。For example, in the 16KG pulsator washing machine in one embodiment of the present invention, the speed sensor is disposed on the motor 200, and the load is divided into five steps according to performance standards.
电机驱动内筒转动特定的时间T，此时间的设定应小于空载达到最高转速的时间，为达到良好的区分度，此时间不宜过小，以避免无法进行转速区分或者负载缠绕。经多次试验，该型号机型T＝5S。对采集不同重量负载的转速信号，如图2所示，为不同负载下内筒的转速曲线。The motor drives the inner cylinder to rotate for a specific time T. The setting of this time should be less than the time when the no-load reaches the maximum speed.

As shown in FIG. 4, the method includes the following steps: S1: establishing an index table, where the index table includes a plurality of speed intervals and corresponding weight intervals, and the speed The interval is a section of the rotation speed of the washing machine after being started for a predetermined time; S2, the current load is placed in the inner cylinder, and the rotation speed of the predetermined rotation time after the inner cylinder is started is obtained; S3, the weight interval corresponding to the rotation speed is determined according to the index table To determine the weight interval in which the current load falls. In step S1, an index table is established. The index table includes a plurality of rotation speed sections and corresponding weight sections, and the rotation speed section is a section of the rotation speed of the washing machine after the inner cylinder is started to rotate for a predetermined time.
具体地，假设该索引表中多个转速区间的数目为n，则第n个转速区间的转速为(RPM(n-1)，RPM(n))，对应的重量区间为(M(n-1)，M(n))，其中，n为正整数。该索 引表的建立过程如下：Specifically, assuming that the number of the plurality of rotational speed sections in the index table is n, the rotational speed of the nth rotational speed interval is (RPM(n-1), RPM(n)), and the corresponding weight interval is (M(n- 1), M(n)), where n is a positive integer. The cable The establishment process of the index table is as follows:

(2)用速度传感器检测内筒转动每种重量的负载启动后转动预定时间T的转速，在同一时刻T，因负载重量不同所获取的转速将不同；(2) Using the speed sensor to detect the rotation speed of the inner cylinder for each weight of the load after the start of the rotation for a predetermined time T, at the same time T, the speed obtained by the load weight will be different;
(3)同一时刻T，不同负载重量M(n)，将对应不同的转速RPM(n)，处理器对照不同负载重量区间(M(n-1)，M(n))，将转速划分为n+1个转速区间。(3) At the same time T, different load weights M(n) will correspond to different rotational speeds RPM(n), and the processor will divide the rotational speed into different load weight intervals (M(n-1), M(n)). n+1 speed intervals.
步骤S2，将当前负载置于内筒内，并获取内筒启动后转动预定时间的转速。In step S2, the current load is placed in the inner cylinder, and the rotation speed of the predetermined time after the inner cylinder is started is obtained.
步骤S3，根据索引表确定转速对应的重量区间，从而确定当前负载落入的重量区间。In step S3, the weight interval corresponding to the rotation speed is determined according to the index table, thereby determining the weight interval in which the current load falls.
当检测到当前负载的转速rpm满足：RPM(n-1)≤rpm<RPM(n)时，则判定重量区间为(M(n-1)，M(n))。处理器根据当前负载的转速确定其对应的重量区间，以便洗衣机控制器根据当前负载的重量区间进行相应方式的洗涤及脱水。When it is detected that the rotational speed rpm of the current load satisfies: RPM(n-1)≤rpm<RPM(n), it is determined that the weight interval is (M(n-1), M(n)).

The setting of this time should be less than the time when the no-load reaches the maximum speed. In order to achieve a good discrimination, this time should not be too small to avoid the possibility of speed discrimination or load winding. After many tests, this model is T=5 seconds. For collecting the speed signals of different weight loads, as shown in Figure 2, the speed curve of the inner cylinder under different loads.
当检测到内筒运行T时间后的转速为rpm时，与转速区间(RPM(n-1)，RPM(n))进行对比，对应得到洗衣机中当前负载的重量区间为(M(n-1)，M(n))。并依据当前负载的重量M(n)来选择最佳的洗涤与脱水方式。结合图2和图3，不同负载的转速区分如下：When it is detected that the rotation speed of the inner cylinder after running T time is rpm, compared with the rotation speed interval (RPM(n-1), RPM(n)), the weight interval corresponding to the current load in the washing machine is (M(n-1). ), M(n)). The optimal washing and dehydrating method is selected according to the weight M(n) of the current load.
