Description

定位装置和包括该定位装置的洗衣机 技术领域
本发明属于衣物清洗设备领域，具体提供一种定位装置和包括该定位装置的洗衣机。
背景技术
目前常用的滚筒洗衣机都是侧开门式，但是该侧开门式洗衣机在使用时，需要用户弯腰或蹲下从洗衣机的侧门向滚筒内投放衣物或者将滚筒内的衣物取出，影响用户(尤其是对于老人)的使用体验。
为此，顶开门式滚筒洗衣机(如公开号为CN1244730C的专利申请文件中公开的滚筒洗衣机)应用而生。与洗衣机的顶开门相对应的，滚筒的周向也设置有滚筒门，在洗衣机停止转动且滚筒门与洗衣机的顶开门相对应时，通过滚筒锁定装置对滚筒进行锁定。具体地，通过将滚筒锁定装置的锁舌插进皮带轮的凹槽内，实现滚筒锁定装置对滚筒的锁定
但是，在滚筒锁定装置对滚筒进行锁定之前需要对滚筒进行精确定位，否则滚筒锁定装置将不能够对滚筒进行锁定，甚至会损坏滚筒锁定装置的锁舌。
相应地，本领域需要一种新的滚筒定位装置来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有顶开门式滚筒洗衣机的滚筒在定位不精确时锁舌不能够插进皮带轮的凹槽内进而不能够锁定滚筒的问题，本发明提供了一种定位装置，所述定位装置用于对洗衣机的滚筒进行定位，所述定位装置包括锁定模块，该锁定模块包括：锁体，其固定于所述洗衣机的机体上或者与所述机体一体形成；锁舌，其至少一部分位于所述锁体内，并且所述锁舌能够沿其长度方向相对于所述锁体滑动；摩擦件，其设置于所述锁舌的一端，并且在所述 锁舌从所述锁体内伸出时所述摩擦件能够与所述滚筒摩擦接触并因此将所述滚筒锁定在预定位置。
在上述定位装置的优选技术方案中，所述滚筒的一端连接有皮带轮，所述摩擦件通过抵靠并压紧所述皮带轮来锁定所述滚筒。
在上述定位装置的优选技术方案中，所述摩擦件的摩擦面形状设置成与所述皮带轮的形状匹配。
在上述定位装置的优选技术方案中，所述锁定模块还包括电机，所述电机用于驱动所述锁舌从所述锁体伸出或缩回所述锁体中。
在上述定位装置的优选技术方案中，所述锁定模块还包括设置在所述锁体与所述锁舌之间的弹簧，在所述电机驱动所述锁舌伸出时，所述弹簧能够使所述摩擦件压紧所述皮带轮。
在上述定位装置的优选技术方案中，所述定位装置还包括位置检测模块，所述位置检测模块用于检测所述滚筒的旋转位置。
在上述定位装置的优选技术方案中，所述定位装置还包括控制模块，所述控制模块用于基于所述位置检测模块检测到的位置信号控制所述锁舌。
在上述定位装置的优选技术方案中，所述位置检测模块包括设置在所述皮带轮上的磁体和设置在所述机体上的霍尔元件，并且所述霍尔元件与所述磁体的旋转路径相对应。
在上述定位装置的优选技术方案中，所述磁铁设置在所述皮带轮的轮辐上。
在另一方面，本发明提供了一种洗衣机，所述洗衣机包括上述定位装置的优选技术方案中任一项所述的定位装置。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过在锁体的锁舌的端部设置摩擦件，使得锁舌在将摩擦件顶出并压紧皮带轮时能够通过摩擦接触对滚筒进行锁定。相对于现有技术中通过将锁舌插入皮带轮上的凹槽内对滚筒进行锁定的方式，本发明通过摩擦件和皮带轮之间的压紧力对滚筒进行锁定的方式，不需要对滚筒精确定位也能够实现滚筒的锁定。
进一步，通过将摩擦件的摩擦面设置成能够与皮带轮的轮缘的弧形面，能够增加摩擦件与皮带轮之间的接触面积，进而在相同压紧力的情况下，摩擦件与皮带轮之间能够获得更大的摩擦力。通过在锁体 和锁舌之间设置弹簧，能够保证摩擦件与皮带轮相抵触时摩擦件始终压紧皮带轮，防止滚筒发生转动。更进一步，通过在摩擦件靠近皮带轮的一侧设置摩擦片，能够有效地提高摩擦件的使用寿命。
附图说明

1、锁定模块；11、锁体；12、锁舌；13、摩擦件；14、摩擦片；2、皮带轮；21、轮辐；3、磁铁；4、霍尔元件。
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，并非用于限制本发明的保护范围。例如，虽然附图中的各部件之间是按一定比例关系绘制的，但是这种比例关系并非一成不变，本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。
需要说明的是，在本发明的描述中，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述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。
此外，还需要说明的是，在本发明的描述中，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，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
如图1所示，本发明的定位装置具有锁定模块1，该锁定模块1主要包括锁体11、锁舌12和摩擦件13。虽然图中并未示出，但是锁体11固定连接至洗衣机的机体上，具体地，锁体11通过螺栓固定连接至洗衣机的机体上，或者本领域技术人员还可以根据需要，通过其他 的连接方式将锁体11固定连接至洗衣机的机体上，例如焊接。此外，本领域技术人员还可以根据需要将锁体11和机体设置为一个整体。从图1中不难看出，锁舌12的一部分位于锁体11内，并且锁舌12能够沿其长度方向相对于锁体11进行滑动，优选地，该锁舌12的轴线指向皮带轮4的轴线且相互垂直或接近垂直。摩擦件13位于图1中锁舌12的上端，并且摩擦件13和锁舌12固定连接，本领域技术人员可根据需要，使摩擦件13和锁舌12通过螺栓连接的方式、螺纹连接的方式、焊接的方式或者其他任何可行的连接方式固定到一起，或者使摩擦件13和锁舌12一体成型为一个整体。
进一步，锁舌12能够携带摩擦件13向上(图1的上方)滑动，并使摩擦件13与皮带轮2相抵触。需要说明的是，皮带轮2与洗衣机的滚筒固定连接，优选地，皮带轮2与洗衣机的滚筒同轴固定连接，或者本领域技术人员也可以根据需要使皮带轮2与滚筒通过其他的连接方式进行连接，例如，使皮带轮2与滚筒通过皮带进行连接。当摩擦件13与皮带轮2相抵触且摩擦件13压紧皮带轮2时，皮带轮2被锁定，进而与皮带轮2同轴固定的滚筒被锁定。
继续参阅图1，在本发明的优选实施方案中，摩擦件13的摩擦面(图1中摩擦件13的上端面)具有能够与皮带轮2的轮缘相匹配的弧形面结构。优选地，在摩擦件13与皮带轮2相抵触时，摩擦件13的弧形面的圆心与皮带轮2的圆心重合，以便摩擦件13与皮带轮2之间能够获得更大的接触面积，进而能够增加摩擦件13与皮带轮2之间的摩擦力。从而摩擦件13能够快速地对皮带轮2和滚筒进行锁定。进一步，为了减少摩擦件13长期工作过程中的磨损，在摩擦件13靠近皮带轮2的一侧(即图1中摩擦件13的上端面)还设置有由耐磨材料制成的摩擦片14。
此外，虽然图中未示出，但是锁体11和锁舌12之间还设置有弹簧，该弹簧能够在锁舌12向图1的上方移动且使摩擦片14与皮带轮2接触时，给锁舌12一个向上的力，以便摩擦片14能够始终压紧皮带轮2对皮带轮2进行锁定。进一步，本发明的定位装置还包括用于驱动锁舌12伸出或缩回锁体1的电机。
继续参阅图1，本发明的定位装置还包括位置检测模块和控制模块，该位置检测模块主要由磁铁3和霍尔元件4构成。其中磁铁3 还可以被其他具有磁性的磁体代替，如电磁线圈。磁铁3设置在皮带轮2的轮辐21上，霍尔元件4设置在洗衣机的机体上，且霍尔元件4的位置与磁铁3的旋转路径相对应，以便霍尔元件4能够准确地检测到磁铁3的磁通信号。控制模块能够在霍尔元件4检测到磁铁3的磁通信号时控制电机使锁舌12伸出。需要说明的是，磁铁3的旋转路径是磁铁3绕皮带轮2的轴心旋转一圈的圆形路径，霍尔元件4位于该圆形路径上，因此，磁铁3在旋转一整圈的过程中，必然会到达一个与霍尔元件4对准的位置。
此外，本领域技术人员还可以根据需要，对磁铁3和霍尔元件4的设置位置进行适当调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。进一步，除了磁铁3和霍尔元件4，本领域技术人员还可以通过其他的位置检测模块对滚筒的旋转位置进行检测，例如，设置在皮带轮2上的角度传感器。
下面结合顶开门式滚筒洗衣机来对本发明的定位装置的原理进行详细说明。
当顶开门式滚筒洗衣机未工作时，滚筒处于预定位置，即此时的洗衣机的顶开门与滚筒周向上的滚筒门相对应，用户可打开顶开门和滚筒门向滚筒内投放衣物或将滚筒内的衣物取出。此时锁舌12伸出，摩擦片14压紧皮带轮2，滚筒被锁定。
当顶开门式滚筒洗衣机工作且脱水完成时，通过皮带驱动皮带轮2的电机会在洗衣机变频器的控制下低速旋转，当霍尔元件4检测到磁铁3的信号时，该电机马上停止转动，与此同时或之后(如延时0.5S之后)控制模块控制电机使锁舌12伸出，将摩擦片14抵触至皮带轮2上，并将皮带轮2顶紧。在摩擦片14与皮带轮2之间摩擦力的作用下，皮带轮2被制动锁定。
本领域技术人员能够理解的是，滚筒门在皮带轮2被锁定时的所在位置，相对于滚筒门在霍尔元件4检测到磁铁3时的所在位置具有一定的角度差。因此，应将顶开门设置为大于滚筒门的开口，或者也可以通过实验获取该角度差，将滚筒门沿滚筒的转动方向偏置一个该角度差。从而方便用户将衣物放入滚筒内或从滚筒内将衣物取出。
需要说明的是，虽然本发明的定位装置主要应用于顶开门式滚筒洗衣机，但是很显然本发明的定位装置还可以应用于其他形式的洗 衣机，本领域技术人员可根据需要对其进行调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。
综上所述，本发明的定位装置通过摩擦件13和皮带轮2之间压紧力对滚筒进行锁定的方式，相对于现有技术中通过将锁舌插入皮带轮上的凹槽内对滚筒进行锁定的方式，能够在不对滚筒精确定位的情况下实现滚筒的锁定。
进一步，通过将摩擦件13设置成具有弧形面的结构，能够增加摩擦件13与皮带轮2之间的接触面积，进而在相同压紧力的情况下，摩擦件13与皮带轮2之间能够获得更大的摩擦力。通过在锁体11和锁舌12之间设置弹簧，能够保证摩擦件13与皮带轮2相抵触时摩擦件13始终压紧皮带轮2，防止滚筒发生转动。更进一步，通过在摩擦件13靠近皮带轮的一侧设置摩擦片14，能够有效地提高摩擦件13的使用寿命。
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。
