具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。例如，尽管本发明的技术方案是基于波轮洗衣机来描述的，但是这并不是限制性的，本发明的技术方案也可以应用于其他类型的洗衣机，例如滚筒洗衣机。
基于背景技术中关于现有洗衣机的漂洗性能不佳的问题，本发明提供了一种洗衣机的漂洗方法，旨在提高洗衣机的漂洗性能，降低洗衣液(粉)的残留量，同时实现节水节电。总体而言，该漂洗方法包括以下步骤：S1：以喷淋方式向洗衣机的内筒中注入预定量的清水；S2：控制循环泵进行内循环以将水循环至洗衣机的内筒中。
实施例一
参见图1和图2，图1是本发明的洗衣机的漂洗方法的流程图，图2为本发明的洗衣机的结构示意图。如图1所示，本实施例的漂洗方法包括以下步骤：S1：通过洗衣机注水口1以喷淋方式向洗衣机的内筒2中注入预定量的清水；S2：控制循环泵3将水循环至内循环喷水口4；S3：将水通过内循环喷水口4以喷射方式注入到洗衣机的内筒2中。优选地，在执行上述各个步骤期间，控制洗衣机的内筒2低速转动。具体地，在本实施例中，先通过注水口1以喷淋方式向洗衣机的内筒2中注水，同时控制洗衣机的内筒2转动，当注入的水量达到预定程度时，注水口1停止喷淋注水，然后通过循环泵3将内筒2中蓄积的水经过内循环喷水口4重新喷射到洗衣机的内筒2中，使水对衣物再次进行冲刷漂洗。通过发明人反复试验、观测和比较，通过本实施例的漂洗方法，既能够获得喷雾式漂洗的漂洗效果，还能够实现水的重复利用，极大地降低了衣物上洗衣液(粉)的残留，同时达到了节水节电的目的。
关于步骤S1，需要说明的是，所述“喷淋”意指使进入洗衣机的水像下雨一样撒落在内筒2中的负载5上，其不同于普通洗衣机的“成股进水”，也不同于喷雾式进水，介于二者之间。当然，所述喷淋的水滴大小没有任何限制，本领域技术人员可以根据需要合理设置。
在上述漂洗方法中，控制循环泵3采用喷射的方式将水喷入洗衣机的内筒2中，即喷出的水会向远离内循环喷水口4一侧的内筒2的内壁上喷射，具体可参见图2(图2中正是这种状态)。如图2所示，在步骤S3的喷射过程中，内循环喷水口4能够向洗衣机的内筒2中喷射形成抛物状的水流，所述抛物状的水流具有上边界和下边界，所述上边界与内筒2内的负载5相交于第一点，所述第一点至内筒2的内底面的高度为H，所述下边界与内筒2内的负载5相交于第二点，所述第二点至内筒2的内底面的高度为H1，其中：H1＜H。所述上边界的形状和所述下边界的形状均为弧形，所述上边界为a，所述下边界为b，内循环喷 水口4喷射的水流在a和b之间形成喷射区域，此喷射区域为喷射的有效区域，其中H和H1的高度均与内筒2的直径、筒高和负载5的量相关。
需要说明的是，上述负载5既可以为洗衣机内的衣物，也可以为便于内筒2稳定旋转的惯性平衡块，还可以为用于揉搓衣物的摩擦球(块)，以及衣物与平衡块和/或摩擦球(块)的组合。
优选地，所述第一点为负载5的最高点，所述第二点至内筒2的内底面的高度H1的范围为大于等于H/4且小于等于H/3。经过发明人的反复试验和对比，这种喷射设置使得能够获得最佳的漂洗效果，最大程度地减少衣物内的洗衣液(粉)残留。
优选地，步骤S1中的喷淋方式和步骤S3中的喷射方式可以采用间歇式喷水，采用间歇式喷水可以灵活控制喷水的周期以及每次喷水的量。实验结果显示，这种特殊的喷水方式使得本发明的技术方案在节水节电的同时，还能够获得喷雾式漂洗的效果－即最大程度地降低洗衣液(粉)残留。实际操作时，可以选择喷水2s、停止3s的间歇式喷水，当然，步骤S1的喷淋操作和步骤S3的喷射操作也可以采用不同的时序控制，且喷水时间和停止时间可以根据实际使用情况任意设定。
实施例二
在另一方面，除了采用上述实施例一中的高压喷射喷水方式，还可以采用低压喷淋的喷水方式，即喷出的水会向靠近内循环喷水口4一侧的内筒2中喷淋，并落到靠近内循环喷水口4一侧的负载5上(即图2中右侧的负载5上)。相应地，本实施例的漂洗方法包括以下步骤：S1：通过洗衣机注水口1以喷淋方式向洗衣机的内筒2中注入预定量的清水；S2：控制循环泵3将水循环至内循环喷水口4；S3：将水通过内循环喷水口4以喷淋方式注入到洗衣机的内筒2中。与第一个实施例类似，在执行上述各个步骤期间，控制洗衣机的内筒2低速转动。具体地，在本实施例中，先通过注水口1以喷淋方式向洗衣机的内筒2中注水，同时控制洗衣机的内筒2转动，当注入的水量达到预定程度时，注水口1停止喷淋注水，然后通过循环泵3将内筒2中蓄积的水经过内循环喷水口4重新喷淋到洗衣机的内筒2中，使水对衣物再次进行喷淋漂洗。实验结果显示，通过本实施例的漂洗方法，能够获得与实施例一基本相同的技术效果，既能够获得喷雾式漂洗的漂洗效果，还能够实现 水的重复利用，极大地降低了衣物上洗衣液(粉)的残留，同时达到了节水节电的目的。
与实施例一类似，在实施例二中，在执行步骤S1和步骤S3期间，喷淋方式可以采用间歇式喷淋。如上所述，这种喷淋方式同样能够使得本发明的技术方案在节水节电的同时，还能够获得喷雾式漂洗的效果－即最大程度地降低洗衣液(粉)残留。
在上述实施例一和实施例二中，步骤S1中向洗衣机的内筒2中喷淋注入的清水的预定量需要能够满足漂洗的要求，使得有足够量的清水能够实现内循环喷水操作。本领域技术人员可以根据洗衣机的尺寸和待漂洗衣物的量来合理选择注入清水的数量。同时，为了使注水口1能够以喷淋方式向洗衣机的内筒2中注水，可以在注水口1上设置诸如花洒结构的喷淋头，以实现经由注水口1的水能够以喷淋形式注入到洗衣机的内筒2中。替代性地，也可以通过改变洗衣机的进水阀结构来实现喷淋进水。当然，图2所示的注水口1的位置只是一个示例，在实际的应用中，注水口1可以位于任意能够向洗衣机的内筒2中实现喷淋操作的位置，这种位置的变化并不偏离本发明的原理和范围。
如上所述，在执行步骤S1、S2和S3期间，即在洗衣机进行喷淋加内循环喷水漂洗操作期间，洗衣机内筒2被控制以设定速度旋转，其中该设定速度应为低速，从而保证水不会溅出，也不能达到共振点。具体数值可以根据应用场合的需要来任意选取，该数值的变化不构成对本发明的限制。具体地，在洗衣机的机型中，可以分为定频洗衣机和变频洗衣机，因此，在执行步骤S1、S2和S3期间，两种类型的洗衣机需要采用不同的驱动运转方式。当洗衣机为定频洗衣机时，控制定频电机驱动洗衣机内筒2间歇式旋转，内筒2可以按照开d1秒停e1秒进行低速循环旋转，其中，d1和e1的数值和大小关系可以根据需要灵活选取。当洗衣机为变频洗衣机时，控制变频电机驱动洗衣机内筒2以设定速度持续转动，其中，内筒2可以按照速度a1持续低速旋转，其中，a1的数值也可以根据需要灵活选取。
优选地，在执行步骤S1、S2和S3期间，洗衣机都处于不排水的状态，从而保证洗衣机中的水量足够实现内循环操作。
上面所述的漂洗方法主要包括依次进行的喷淋操作和内循环喷水操作。但是，从广义上讲，本发明的漂洗方法还可以包括漂洗的 准备阶段和漂洗的后处理阶段，其中，漂洗的准备阶段和漂洗的后处理阶段均可以包括依次进行的排水、间歇脱水、连续脱水、间隔脱水和刹车操作，而且，根据洗衣机机型的不同，可以设定不同的排水和脱水时序。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
