本发明涉及洗衣设备技术领域，具体地，涉及一种免清洗节水洗衣机及其控制方法。
背景技术
现有的洗衣机包括壳体以及设置在壳体内的外桶、内桶，内桶可转动的设置在外桶内。为了实现衣物的脱水功能，内桶的桶壁上布满了脱水孔，这样在进行衣物洗涤时，洗涤水会由脱水孔流至内桶与外桶之间，这部分洗涤水不能得到充分的利用而导致水资源的浪费。
另外，由于内桶与外桶之间存水的问题，会导致在内桶的外壁、外桶的内壁以及内桶与外桶之间的区域滋生污垢，污染用户衣物，严重影响用户的洗衣体验。
为了解决上述问题，现有一种洗衣机，其主要的结构特点是内桶的桶壁上无孔，这样，在洗涤时，只在内桶中有水，内桶与外桶之间无水，不仅节省了洗衣的用水量，而且杜绝了内桶与外桶之间滋生污垢，避免衣物污染，提高洗涤效果，提升用户体验。
上述在洗涤时内桶与外桶间无水的洗衣机由于內桶的桶壁上无孔，现有的排水方式不能实现排水；而且，在使用一段时间以后，由于内桶上无孔，洗涤后的泥沙等杂物可能无法及时排出，影响用户洗衣效果。
有鉴于此，特提出本发明。

具体实施方式
下面结合附图对本发明的一种免清洗节水洗衣机及其控制方法进行详细描述：
实施例一
如图1-图6所示所示，本实施例的一种免清洗节水洗衣机，包括，
外桶100；
內桶200，可转动的设置在外桶100内；
內桶轴702，与內桶200连接用于驱动其转动；
在洗涤/漂洗过程中，所述的内桶200为盛水桶，内桶200与外桶100之间无水；
所述內桶200的底部开设排水孔204；所述内桶200的底部外侧设置封水装置，封水装置包括分别套设在內桶轴702外的封水组件和拉环组件500，封水组件安装在内桶200的底部且可随着內桶转动，拉环组件500与封水组件可相对转动的连接；所述的拉环组件500可拉动封水组件沿着內桶轴向运动以打开/关闭排水孔204。
本实施例的封水组件在洗涤/漂洗过程保持排水孔204关闭，避免洗涤水进入到内桶200与外桶100之间的区域，保持桶间无水，避免滋生污垢，污染用户衣物。在排水过程中，拉环组件受到拉力沿內桶轴向运动，拉动封水组件，排水孔204打开，不仅实现排水，还可以将洗涤过程中的泥沙等杂物排出，保持内桶内的清洁。
本实施例封水装置的封水组件安装在內桶200上且随着一起转动，确保封水组件与排水孔204的相对位置固定，这样，在进行排水孔204的关闭/开启时，只需要拉动封水组件500沿內桶轴向运动，而不必要进行定位操作，简单方便，易于实现。拉环组件500套设在封水组件外且不影响封水组件随着內桶一起转动，只在拉环组件沿內桶轴向拉动封水组件时才会拉动封水组件一起运动，将排水孔204打开，进行排水，即使拉环组件500拉动封 水组件时也不阻碍封水组件随着內桶一起转动。
本实施例封水装置在洗涤过程中的状态为：拉环组件500不受力，封水组件保持排水孔204关闭，拉环组件500套设在封水组件外且与其间隔设置，这样，封水组件随着內桶200一起转动保持排水孔204关闭，且与拉环组件500之间不接触，避免摩擦和产生噪音。
如图2所示，本实施例的免清洗节水洗衣机，所述的內桶200包括內桶底和与其连接的內桶法兰203，內桶法兰203的中心具有用于连接內桶轴702的连接部；所述的排水孔204设置在连接部外部的內桶底和/或內桶法兰203上。本实施例将排水孔204设置在內桶200的底部除去连接內桶轴702之外的区域，才能实现与套设在內桶轴702外的封水组件进行配合。
优选地，所述的连接部为设置在內桶法兰203中心的减速器安装孔，所述的排水孔204设置在减速器安装孔的外周圈，优选地，排水孔204设置1～6个，以满足排水要求。
作为本实施例的一种优选实施方式，本实施例的的封水组件包括封水套400，封水套400套设在內桶轴702外，封水套400可沿內桶轴向运动的安装在內桶200的底部外侧，封水套400设有与排水孔204相配合的封水塞407。
具体地，如图8及图9所示，本实施例的封水套400包括环形套体和沿着环形套体周向设置的多个连接臂401，环形套体套套设在內桶轴702外，连接臂401上开设安装孔405，所述的封水塞407设置在环形套体内部。所述的封水塞407与封水孔的位置及数量均分别对应，优选地，所述的封水塞407设置1～6个。
如图2所示，本实施例所述的封水组件还包括柱状安装件202和弹性件，柱状安装件202穿过安装孔405将封水套400安装在內桶200的底部外侧，弹性件的一端固定，另一端止抵于封水套400上用于保持排水孔204关闭。本实施的封水套400通过柱状安装结构202安装在內桶400的底部，封水套400可相对于柱状安装结构202上下运动，因此，封水套400的连接臂401的壁厚小于柱状安装件202的长度。
优选地，所述的连接臂401至少包括三个，沿着环形套体的周向均匀分布，柱状安装件202与连接臂401的数量相等。这样，可保证封水套400安装在內桶200的底部的稳定性且限制其周向转动，以保证封水套400的封水塞407与排水孔204相对，以实现控制排水孔204打开与关闭的目的。
作为本实施例的一种优选实施方式，所述的弹性件为压缩弹簧1700，所述的压缩弹簧1700套设在柱状安装件202上，压缩弹簧407的一端止抵于柱状安装件202上，另一端止抵于封水套400的连接臂401上。本实施例通过压缩弹簧407对封水套400施加压力以使 得封水塞407将排水孔204密封，当需要排水时，拉环组件500拉动封水塞407向下运动，封水塞407由排水孔204中脱出，排水孔204打开，进行排水。
作为本实施例的一种优选实施方式，所述的拉环组件500包括环形体501和拉杆503，所述的环形体501套设在封水套400上，封水套400具有用于限制环形体501沿內桶轴向脱出的限位部；所述的拉杆503沿着环形体501的周向分布，拉杆503的一端与环形体501连接，另一端连接可驱动其沿內桶轴向运动的驱动装置。
为了实现拉环组件500将封水套400拉动，所述的拉环组件500的环形体501向内延伸形成限位端壁504，所述的封水套400的环形套体的外壁上起一圈环形筋形成凸环402。所述封水套400的环形套体上除凸环402之外区域的外径小于限位端壁504的内径，这样，可保证封水套400可相对于拉环组件400转动。所述封水套400的环形套体上凸环402的外径大于限位端壁504的内径，这样可保证拉环组件500沿內桶轴向运动拉动封水套400运动。
进一步地，所述外桶100的底部开设导向柱孔105，所述拉杆502穿过导向柱孔105与驱动装置连接；所述拉杆502与导向柱孔105之间设置波纹密封套1900进行密封。本实施例将驱动装置安装在外桶100的外部，避免进水，且无需密封。将拉杆502穿出外桶100外部，并通过波纹密封套1900进行动密封，避免发生漏水现象。
进一步地，所述的拉杆502上设置限位凸起502，波纹密封套1900止抵于限位凸起502上，用于限定波纹密封套1900脱落，确保密封性。
作为本实施例的一种优选实施方式，本实施例所述的驱动装置包括同轴设置的电磁线圈1500和环形磁体2000，所述的拉杆502连接环形磁体2000。具体地，可将电磁线圈1500和环形磁体2000套设在同一轴上，将电磁线圈1500固定，将环形磁体2000间隔设置在电磁线圈1500的上部且可相对轴滑动，这样，当电磁线圈1500通电形成磁场，环形磁体2000受电磁线圈1500的磁场力吸引沿轴向下滑动，拉环组件500在环形磁体2000的带动下向下运动。
本实施例所述內桶200的侧壁上低于洗衣机最高水位的区域为无孔桶壁。因此，本实施例的內桶法兰203、内桶底和桶体围成不漏水的内桶，所述桶体的上部的投放口上安装平衡环。桶体与桶底，內桶法兰203共同构成一个不漏水的内桶，内部盛水用于洗涤衣物。
本实施例的脱水孔设置位置可保证在洗涤/漂洗时，洗涤水不会由脱水孔排出，而在脱水时，甩出的水会由脱水孔排出到外桶，进一步被排出。
本实施例桶体上靠近平衡环的一端设置一圈脱水孔，平衡环内侧部分伸入到桶体内部， 而脱水孔设置正对着平衡环，这样平衡环可以遮挡这一圈脱水孔，可保持內桶观感上的无孔。
本实施例的洗衣机还包括减速离合器，减速离合器包括內桶轴702和波轮轴701，所述的波轮轴701穿过外桶100的底部和內桶200的底部与设置在內桶200底部的波轮300连接，波轮轴701带动波轮转动搅拌洗涤水进行衣物洗涤。內桶轴702为套设在波轮轴701外的轴套，內桶轴702穿过外桶100的底部与內桶200的內桶法兰203固定连接，以带动內桶200转动。
本实施例的外桶100的底部设置排水口101，所述的排水口101连接排水管800，以将洗涤水排出至洗衣机外部。
另外，本实施例的免清洗节水洗衣机在进水过程中可采用称重、超声波检测等方式进行水位检测。
同时，本实施例免清洗节水洗衣机的控制方法，包括：
洗衣机进行洗涤/漂洗过程，封水组件保持排水孔关闭，内桶与外桶之间保持无水；
洗衣机进行排水过程，控制拉环组件沿着內桶轴向运动，拉环组件拉动封水组件运动，排水孔打开进行排水；
洗衣机进行脱水过程，封水组件复位保持排水孔关闭。
本实施例的免清洗节水洗衣机的控制方法，在洗涤/漂洗过程中，内桶与外桶之间保持无水，不仅节省了洗衣的用水量，而且杜绝了内桶与外桶之间滋生污垢，避免衣物污染，提高洗涤效果，提升用户体验。
在排水过程，控制拉环组件沿着內桶轴向运动，拉环组件拉动封水组件运动，排水孔打开进行排水，同时还可以将洗涤过程中的泥沙等杂物排出，保持内桶内的清洁。
洗衣机进行脱水过程，封水组件复位保持排水孔关闭，避免拉环组件500与封水套400相互接触产生磨损，保持脱水过程的稳定，同时可杜绝噪音产生。
本实施例脱水过程中，水从內桶的上方的脱水孔通过离心力甩出至外桶100，由外桶100的排水孔101排出。
实施例二
如图1-图13所示，本实施例的一种免清洗节水洗衣机，包括，
外桶100；
內桶200，可转动的设置在外桶100内；
內桶轴702，与內桶200连接用于驱动其转动；
在洗涤/漂洗过程中，所述的内桶200为盛水桶；
所述內桶200的底部开设排水孔204；所述内桶200的底部外侧设置封水装置，封水装置包括分别套设在內桶轴外的封水组件和拉环组件500，所述的拉环组件500与封水组件可相对转动的连接，拉环组件500可拉动封水组件沿着內桶200轴向运动以打开/关闭排水孔204，所述封水组件的一端与內桶密封连接，另一端在拉环组件500的拉动下与外桶100密封连接/断开；
还包括水位检测装置，水位检测装置的检测端接通至封水组件内部。
本实施例的水位检测装置与封水组件内部连通，在进水过程中，控制拉环组件500拉动封水组件沿着內桶轴向运动以打开排水孔，洗涤水进入封水组件内部，实现水位检测装置进行水位检测。
另外，封水组件的一端与內桶密封连接，另一端在拉环组件的拉动下与外桶密封连接或断开，这样进水只存在于封水组件内部，避免洗涤水存在于內桶200与外桶100之间除封水组件内部以外的区域，这样，不仅节省了洗衣的用水量，而且杜绝了内桶与外桶之间滋生污垢，避免衣物污染，提高洗涤效果，提升用户体验。
