一种洗衣机 技术领域
本发明属于洗衣机技术领域，具体地说，涉及一种洗衣机。
背景技术
现有全自动波轮洗衣机的工作模式一般为：洗涤及漂洗时，驱动装置通过减速离合装置驱动波轮正反交替转动，而内桶不动；脱水时，驱动装置通过减速离合装置驱动波轮和内桶同步转动。而随着科技水平的发展和人们对生活质量要求的提高，在洗衣机工作过程中，仅靠波轮转动搅动水流实现衣物的洗涤这一方式对衣物洗涤效果的提升有限，无法满足用户日益提高的需求。因此，如何实现全自动波轮洗衣机的洗涤模式多样化成为亟待解决的问题。
目前较为常见的洗涤模式包括两种，分别是：波轮被驱动转动，内桶不动的全自动模式，以及波轮被驱动转动，内桶自由转动的手搓模式。若要在同一台洗衣机上实现上述两种洗涤模式，则需要对传动机构的结构进行改进，从而改变驱动方式，实现两种模式的相互切换。
申请号为02804912.8的中国专利公开了一种适合于在洗衣机中使用的产生双向驱动的传动机构，其包括一个动力输入端和两个动力输出端，其中一个动力输出端与一个搅拌器轴(10)相连，并使搅拌器轴沿一第一方向转动；而其另一动力输出端与一个内桶轴(11)相连，并使内桶轴沿与第一方向相反的第二方向转动。还公开了一种用于产生双向洗涤的洗衣机以及一种能够在洗衣机中产生双向洗涤的洗涤方法及相关的搅拌器和内桶。该专利通过设计可产生双向动力的传动机构解决了驱动方式单一的问题，但公开的传动机构结构复杂，生产成本较高。
申请号为201310408108.X的中国专利公开了一种全自动洗衣机，包括外桶、内桶、波轮及驱动装置，所述的驱动装置包括至少两个转子和至少一个定子，其中一转子与内桶轴连接，还有一转子与波轮轴连接；所述的驱动装置为变频直驱电机，所述的转子、定子、内桶轴及波轮轴同轴设置，内桶轴中空，波轮轴设于内桶轴中；所述的洗衣机洗涤时波轮与内桶同向转动，或者互为反向转动，或者波轮、内桶之一转动，脱水时波轮与内桶同向同速转动。该专利中的驱动装置包括两个转子，实现了双向动力输出，但具有双向动力输出的驱动装置成本偏高。
有鉴于此特提出本发明。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至图4所示，本发明的洗衣机包括减速离合装置，减速离合装置包括内桶轴4和用于锁定内桶轴4的锁止机构6。内桶轴4的侧壁上设置定位孔，锁止机构6具有可往复运动地插入/抽出定位孔的锁止杆7。减速离合装置还包括用于引导锁止杆7插入定位孔的导向环8。
作为本发明的一种优选实施方式，导向环8套设在内桶轴4外部，对应定位孔开设引导孔9。锁止杆7插入/抽出定位孔的一端沿导向环8周向滑动，通过引导空9插入定位孔中，实现对内桶轴4的锁定。
作为本发明的一种优选实施方式，锁止机构6包括壳体11，壳体11内固定设置沿锁止杆7轴线方形延伸具有一定长度的导向通道，锁止杆7可往复运动的设置在导向通道中。通过导向通道的设计，对锁止杆7进行限位，防止其向其他方向移动与定位孔发生错位。
作为本发明的一种优选实施方式，锁止机构6还包括驱动装置10，驱动装置10通过传动组件带动锁止杆7沿其轴线往复运动插入/抽出定位孔。通过驱动装置10与传动组件带动锁止杆7运动，实现对内桶轴4锁定及解除锁定的控制。
实施例一
如图1至图4所示，本实施例所述的洗衣机包括减速离合装置，所述减速离合装置减速机构，减速机构包括固定连接的内桶轴4和制动轮5，制动轮5套设在内桶轴4外部。洗衣机还包括外桶、内桶、以及可转动的设置在内桶底部的波轮，减速离合装置还包括波轮轴3。内桶与内桶轴4固定连接，波轮与波轮轴3固定连接。本实施例所述的减速机构还包括输入轴1，输入轴1与洗衣机的驱动电机固定连接。洗衣机工作时，驱动电机驱动输入轴1转动，输入轴1通过减速离合装置将动力传输给波轮轴3，使波轮轴3带动波轮在驱动电机的驱动下转动。
减速离合装置还包括用于锁定内桶轴4的锁止机构6，外桶下方安装有固定的安装大板2，锁止机构6固定设置在安装大板2上。内桶轴4的侧壁上设置定位孔，制动轮5与内桶轴4连接的部分对应定位孔的位置开设通孔，锁止机构6具有可往复运动地插入/抽出定位孔的锁止杆7。锁止杆7插入定位孔时，内桶轴4被锁定，洗涤过程中，输入轴1通过减速离合装置将动力传输给波轮轴3，使波轮在内桶底部转动，而内桶因内桶轴4被锁定不随衣物及水流转动，实现了仅波轮转动的全自动洗涤模式。锁止杆7抽出定位孔时，内桶轴4的锁定解除，洗涤过程中，输入轴1通过减速离合装置将动力传输给波轮轴3，使波轮在内桶底部转动，内桶轴4处于自由状态，因而内桶可在衣物和水流的带动下自由转动，实现了波轮受驱转动，内桶自由转动的手搓洗涤模式。
制动轮5外部固定套设用于引导锁止杆7插入定位孔的导向环8，导向环8对应定位孔的位置开设引导孔9。在洗衣机由手搓洗涤模式切换到全自动洗涤模式的过程中，锁止杆7的右端沿导向环8的周向滑动，当锁止杆7与定位孔的位置对应时，锁止杆7经过引导孔9插入定位孔中，实现对内桶轴4的锁定。
在本实施例的一种优选方案中，导向环8上设有沿其周向延伸的导向滑槽，锁止杆7右端可移动的设置在导向滑槽中，与导向滑槽的表面间隙配合。通过导向滑槽对锁止杆7的右端进行限位，确保其在定位孔所在高度的周向进行滑动定位，避免了锁止杆7右端跑偏无法插入定位孔的情况。锁止杆7与导向滑槽间隙配合，即实现了对锁止杆7的限位效果，又避免了滑动过程中锁止杆7右端发生磨损的情况。
在本实施例的另一种优选方案中，导向环8由柔性材料制成，锁止杆7右端与导向环8的外表面可相对滑动的接触设置。锁止杆7在滑动定位过程中与导向环8接触，以实现对锁止杆7右端的引导作用，由于柔性材料具有较低的硬度，滑动过程不会磨损锁止杆7。所述 的柔性材料可以为橡胶或塑料。采用橡胶材质的导向环8时，导向环8与制动轮5过盈配合，将导向环8直接套在制动轮5外部实现固定连接。采用塑料材质的导向环8时，可以通过卡接、粘接或螺钉固定的方式将导向环8固定在制动轮5外部。
本实施例中，减速离合装置通过锁止杆插入定位孔锁定内桶轴，锁止杆抽出时解除内桶轴的锁定，实现了两种离合状态的切换，在一台洗衣机上实现了两种不同的洗涤模式。通过设置导向环引导锁止杆插入定位孔，使锁定位置的确定更加容易，避免了锁止杆的偏移，锁止结构更加可靠。导向环套设在制动环外部，锁止杆在导向环外侧滑动，不与制动轮侧壁直接接触，避免了制动轮侧壁与锁止杆的磨损，同时避免了锁止杆的滑动产生金属摩擦的异音。
实施例二
如图1至图4所示，为上述实施例一的进一步限定，所述的锁止机构6包括壳体11，壳体11与安装大板2固定连接。壳体11内固定设置沿锁止杆7轴线方形延伸具有一定长度的导向通道，锁止杆7可往复运动的设置在导向通道中。通过导向通道的设计，对锁止杆7进行限位，防止其向其他方向移动与定位孔发生错位。
锁止机构6还包括驱动装置10，驱动装置10通过传动组件带动锁止杆7沿其轴线往复运动插入/抽出定位孔。所述洗衣机具有控制板，驱动装置10与控制板电连接，通过接收控制板的信号对传动组件进行驱动，使锁止杆7插入/抽出定位孔，实现/解除对内桶轴的锁定。具体地，洗衣机具有波轮受驱转动、内桶不转动的全自动洗涤模式，以及波轮受驱转动、内桶自由转动的手搓洗涤模式。当控制板接收到启动全自动洗涤模式的信号时，向驱动装置发出信号，控制驱动装置驱动传动组件，带动锁止杆7插入定位孔中锁定内桶轴4。当控制板接收到启动手搓洗涤模式的信号时，向驱动装置发出信号，控制驱动装置驱动传动组件，带动锁止杆7抽出定位孔解除内桶轴4的锁定。洗涤过程所采用的洗涤模式可以由用户在启动洗衣程序时自行选择，也可以通过对洗衣机的洗涤程序设计，使两种洗涤模式在同一洗涤程序中交替进行。
进一步地，所述的传动组件包括连杆，连杆的一端与驱动装置10连接，可在驱动装置10带动下绕与驱动装置连接的端点转动。锁止杆7的左端设有沿垂直于其轴线具有一定长度的导向槽，连杆的另一端设有连接部，所述连接部可移动的设置在所述导向槽中。通过驱动装置10带动连杆转动，连接部绕连杆与驱动装置连接的端点转动，靠近或远离内桶轴所在位置，连接部同时在导向槽中沿与锁止杆7轴线垂直的方向移动，从而带动锁止杆7在导向通道中往复运动。
本实施例中，通过在锁止机构的壳体内设置导向通道，对锁止杆进行限位，进一步防止其与定位孔发生错位导致锁止机构失效的问题。通过驱动装置与传动组件对锁止杆的动作进行控制，结构简单，易于实现。
实施例三
本实施例与上述实施例二的区别在于：所述的传动组件包括齿轮和齿条，所述齿条固定设置在锁止杆远离定位孔的一端，沿锁止杆的轴线延伸具有一定长度，所述齿轮与齿条配合安装，且可在所述驱动装置带动下转动。当控制板接收到启动全自动洗涤模式的信号时，向驱动装置发出信号，控制驱动装置驱动齿轮正转，带动齿条向定位孔所在方向移动，进而带动锁止杆运动插入定位孔中锁定内桶轴。当控制板接收到启动手搓洗涤模式的信号时，向驱动装置发出信号，控制驱动装置驱动齿轮反转，带动齿条向定位孔所在方向的反方向移动，进而带动锁止杆抽出定位孔解除内桶轴的锁定。
本实施例中，仅改变了传动组件的结构，实现的效果与上述实施例二相同，可以通过驱动装置与传动组件对锁止杆的动作进行控制，实现或解除内桶轴的锁定，进而实现两种洗涤模式的切换。
实施例四
本实施例与上述实施例二的区别在于：所述的传动组件包括凸轮，所述凸轮可在驱动装置带动下转动，所述锁止杆远离定位孔的一端止抵所述凸轮。所述锁止杆固定连接弹性件，所述弹性件的弹性力带动所述锁止杆从定位孔中抽出。当控制板接收到启动全自动洗涤模式的信号时，向驱动装置发出信号，控制驱动装置驱动凸轮转动，将远离转动中心的一端转向锁止杆，向定位孔所在方向推动锁止杆，使锁止杆插入定位孔中锁定内桶轴。当控制板接收到启动手搓洗涤模式的信号时，向驱动装置发出信号，控制驱动装置驱动凸轮转动，将靠近转动中心的一端转向锁止杆，弹性件向锁止杆抽出的方向推动锁止杆，使锁止杆抽出定位孔解除内桶轴的锁定。
本实施例采用不同于实施例二中传动组件的结构，实现的效果与上述实施例二相同，可以通过驱动装置与传动组件对锁止杆的动作进行控制，实现或解除内桶轴的锁定，进而实现两种洗涤模式的切换。
