Description

一种排水控制机构及洗衣机 技术领域
本发明涉及洗衣机领域尤其是一种排水控制机构及洗衣机。
背景技术
现有的波轮式洗衣机，内桶上由透水孔，内外桶之间连通，内桶为洗涤桶，外桶为盛水桶，而内桶与外桶侧壁之间充满的这部分水不参与洗涤，真正参与洗涤的水仅是内桶中的那部分，这使得水资源浪费较大，另外，内外桶之间过多的水也会降低洗涤液中洗涤剂/洗衣粉的浓度。与此同时，由于水流在内桶、外桶之间频繁进出，持续使用之后，内桶与外桶的侧壁之间的区域也成了藏污纳垢的空间，自来水里的水垢、洗衣粉的游离物、衣物的纤维素、人体的有机物及衣物带入的灰尘与细菌极易滞留在内桶与外桶的侧壁之间。这些霉菌是用久了的洗衣机内部积蓄的大量污垢、因不能有效去除而滋生繁殖的，这些使用者看不到的污垢如果不予清除，那么在下一次洗涤后，细菌又会附着在衣物上而带给人体，造成交叉感染的问题。
2()()420107890.8专利涉及一种全自动洗衣机，主要包括箱体、洗涤脱水桶、盛水桶和驱动装置，盛水桶安装在洗涤脱水桶的外面并与箱体固定连接，盛水桶内壁底面与洗涤脱水桶的外壁底面之间设有密封装置，并在密封装置内形成密封腔；洗涤脱水桶外侧壁无通孔，底部设有与密封腔相连通的排水口；盛水桶上开有与排水管相通的排水口，排水管上设有排水阀。
现有研究中也有洗涤时内桶、外桶之间无水的洗衣机，在内桶的上部靠近边缘设有多个甩水孔，内桶的底部设有至少一个内桶排水口，外桶底部设有可封堵排水孔的排水控制机构，排水控制机构至少包括一可伸缩的阀塞，阀塞向上运动关闭排水孔，所述阀塞向下运动打开排水孔。
上述内外桶之间无水的洗衣机中，盛水桶为内桶，而脱水时内桶还需要旋转，就没办法使用现有通过水路/气室/导压管/管卡/水位传感器等一系列结构和部件的组合形成的水位检测结构从外桶上引出检测水位，而如果检测水位需要从内桶引出相应的检测管路，无法实现真正意义上的内外桶隔离，且现有这种水位检测结构比较复杂，组装工 艺比较繁琐，容易出现在检测管路和气室以及检测管路和传感器之间的漏气，从而影响检测的准确性，引起整机故障，复杂的结构导致成本比较高。
鉴于此提出本发明。

一种具有上述排水控制机构的洗衣机。
采用本发明所述的技术方案后，带来以下有益效果：本发明所述排水控制机构的阀塞封堵住排水口后，阀塞正对排水口的位置与内桶中的水接触，在该处设置的水位检测装置后能够检测到内桶中水位的高低，且排水控制机构打开排水口后，水位检测装置随阀塞缩回外桶底，内桶旋转时不会受到任何影响。该种水位检测装置结构简单，故障率低，与排水控制机构整合在一起，降低了成本，且排水控制机构直接检测内桶水位高低，精确度高，无检测用的管路、气室等结构，真正实现了无孔内桶技术的内外桶隔离，避免外桶滋生的细菌造成的交叉感染。
下面结合附图对本发明的具体实施方式作进一步详细的描述。
附图说明
图1：本发明所述洗衣机结构图
图2：本发明所述排水控制机构结构图
图3：本发明阀塞结构图
其中：100、内桶，101、排水口，102、排水孔，103、内桶底，200、外桶，300、排水控制机构，301、阀塞，302、活塞杆，303、波纹管，305、铁芯，306、通电线圈，307、活动片，308、弹性件，309、弹性隔膜，310、容纳腔，311、调整螺钉，312、供电线，313、第一弹簧，314、第二弹簧，315、阀座，316、驱动电机。
具体实施方式
如图1所示，本发明所述的洗衣机，包括内桶100、外桶200，内桶体无与外桶连通的漏水孔，内桶底103设有排水口101，内桶体上部设有一圈排水孔102，洗涤时，排水控制机构控制排水口101关闭，水位低于所述排水孔102的高度，只有内桶100中有水，内桶100和外桶200之间无水，洗涤结束后，排水控制机构控制排水口101开启，大部分水从排水口101中排走，脱水时，内桶100转动，衣物中脱出的水受离心力的作用沿桶壁上升，通过内桶上部的排水孔106排出内桶到内外桶之间，再通过外桶200的 排水口排出，这样洗涤时洗涤水只保存在内桶100中，内外桶之间无洗涤水，节约用水，同时内桶100与外桶200的侧壁之间的区域不会积蓄污垢，使内、外桶之间清洁，避免滋生细菌；排水和/或脱水过程中，排水口101打开，大部分水及泥沙、颗粒等沉积物从下部排水口101排出至外桶中，衣物中的水则在内桶高速旋转脱水时由内桶上部的排水孔102排出至外桶中，直接从外桶底的排水口、排水管排出洗衣机外，实现了快速排水且排水、排污效果好。
本发明在排水口101底部设置控制排水口101打开/关闭的排水控制机构300，排水控制机构300安装在外桶上，排水口101在内桶上，需要封堵排水口101时，控制内桶转动至排水口101正对排水控制机构300的位置，控制排水控制机构300动作，封堵排水口101，需要打开排水口101时控制排水控制机构300动作打开排水口101，内桶就可以旋转了，洗衣过程中，进水、洗涤时排水控制机构300封堵排水口101，控制排水口101关闭，排水、脱水时排水控制机构300控制排水口101开启。
现有洗衣机的水位检测结构包括水路、气室、导压管、管卡、水位传感器，通过水路将水流引到气室，通过检测气室压力的变化检测水位的高低，现有洗衣机的盛水桶为外桶，且外桶是固定的，从外桶中引出水流到气室很容易，但是本申请所述洗衣机内外桶之间无水，盛水桶为内桶，从外桶引导水流到气室已经不能实现水位的检测，而且内桶在脱水的时候是转动的，很难从不固定的内桶中引出水流到气室进行水位检测。
而本申请中实现控制内桶排水的控制机构，在洗涤漂洗等内桶中有水的时候肯定是封堵排水口101的，阀塞能与内桶中的水接触，如图2、图3所示，本申请提出一种排水控制机构300，能够控制排水口101的打开/关闭，同时关闭排水口101后还能够对内桶内的水位进行检测，所述排水控制机构，包括：能封堵排水口的阀塞301、驱动阀塞301运动的活塞杆302，所述阀塞301的端部正对排水口101的位置设置水位检测装置。阀塞301封堵住排水口101后，阀塞301正对排水口101的位置与内桶100中的水接触，在该处设置水位检测装置后能够检测到内桶中水位的高低，且排水控制机构300打开排水口后，水位检测装置随阀塞301缩回外桶底，内桶100旋转时不会受到任何影响。
所述水位检测装置包括通电线圈306、铁芯305和信号检测结构，所述信号检测结构与通电线圈306连接检测通电线圈306中电信号的变化，所述电信号为电流信号或电压信号。优选所述信号检测结构为一检测电路，所述检测电路只要能检测处通电线圈的电流信号或电压信号即可，所述通电线圈306通过信息号连接线将电流信号或电压信号传递给检测电路，检测电路将检测到的电信号传递给洗衣机的控制器。
所述水位检测装置包括固定设置的通电线圈306、随水位高低变化而移动的铁芯305，水位高低变化影响铁芯305的移动，铁芯305在不同位置影响通电线圈306内电流的大小的变化，对通电线圈306内电流的大小进行检测就能得出内桶中水位的高度。不同的水位对应不同的电流值，从而实现水位的精确检测。
或者所述水位检测装置包括固定设置的铁芯305、随水位高低变化而移动的通电线圈306，水位高低变化影响通电线圈306的移动，通电线圈306在不同位置与铁芯305的距离不同，铁芯305对通电线圈306的影响不同，对通电线圈306内电流的大小进行检测就能得出内桶中水位的高度。不同的水位对应不同的电流值，从而实现水位的精确检测。
上述两种情况中所述铁芯305都位于所述通电线圈306的感应范围内，保证铁芯和通电线圈之间的距离的变化会影响线圈中的电流的大小。
该种水位检测装置结构简单，故障率低，与排水控制机构整合在一起，降低了成本，且排水控制机构直接检测内桶水位高低，精确度高，无检测用的管路、气室等结构，真正实现了无孔内桶技术的内外桶隔离，避免外桶滋生的细菌造成的交叉感染。
优选的水位检测装置包括固定设置的通电线圈306、随水位高低变化而移动的铁芯305，因为通电线圈306需要通电还需要对其电信号进行检测，所以将通电线圈306设置成固定的，比较容易安装，所述铁芯305固定在一活动片307上，所述活动片307一侧正对排水口101，另一侧连接一弹性件308，所述弹性件308的另一端固定设置。内桶中的水会直接或间接作用于活动片307上，所述活动片307发生移动，带动铁芯305的位置移动，影响通电线圈306中的电流，检测通电线圈306中的电流，不同的电流值对应不同的水位，从而实现水位的精确检测。
优选所述铁芯305的上端设有一凹部，所述活动片307的下部设有一凸部，活动片的凸部伸入至铁芯的凹部，所述活动片的凸部与铁芯的凹部形状、大小相匹配，所述铁芯的下端设有另一凹部，所述弹性件的端部伸入到铁芯下端的凹部内，实现连接，且铁芯下端的凹部内设有定位柱，弹性件的端部设有定位孔，所述铁芯下端凹部内的定位柱与弹性件端部的定位孔相配合。优选弹性件为弹簧，所述弹簧的端部伸入到铁芯下端的凹部内所述铁芯下端凹部内的定位柱伸入到弹簧的内部实现定位。该种连接方式安装简单，且连接稳定。
所述阀塞301设有一容纳腔310，容纳腔310朝向排水口101的一侧设有开口，开 口处设置弹性隔膜309，所述水位检测结构设置在所述容纳腔310内，所述弹性隔膜309覆盖住阀塞301朝向排水口的一端的部分或全部，优选所述弹性隔膜309覆盖住阀塞301的端部。所述水位检测结构设置在阀塞301内部的容纳腔310内既不影响阀塞对排水口的控制，又能实现水位检测装置对内桶水位的检测。
弹性件308的固定端固定在所述阀塞301的容纳腔310的底部，或者所述弹性件308的固定端伸出阀塞301的容纳腔310的底部固定在所述活塞杆302的顶部，所述活动片307位于所述容纳腔310的顶部，活动片307正对排水口的一侧与弹性隔膜309贴合或固定。内桶内水位升高会向下压缩弹性隔膜309、活动片307和弹性件308，带动铁芯305向下运动，影响通电线圈内的电流，通过检测到的通电线圈内的电信号得出内桶中水位。
所述容纳腔310的底部或者所述活塞杆302的顶部固定所述弹性件处设有调整螺钉311。所述调整螺钉可以对弹性件的位置进行微调，更精确的对水位进行检测。
所述活塞杆302为中空结构，所述活塞杆302的内部设置通电线圈的供电线和/或供电线圈的信号连接线。
阀塞301顶部设有至少一圈密封部，排水控制机构封堵排水口时，所述阀塞顶部的密封部与排水口外周的外桶底紧密贴合，优选所述密封部为弹性结构或者所述弹性隔膜309至少覆盖住阀塞顶部的密封部。该种结构排水口的结构没有过多结构的限制，加工简单。所述弹性隔膜309既起到了密封水位检测装置的作用，又起到了密封阀塞和排水口的作用。
本发明又一实施例中所述排水口101为上大下小的喇叭口结构，排水控制机构封堵排水口时，所述阀塞301伸入排水口，阀塞的顶部与侧部相交处和排水口的内壁紧密贴合，优选阀塞301的顶部与侧部相交处为弹性结构或者所述弹性隔膜309覆盖住阀塞顶部全部且向下弯折至覆盖住部分阀塞的侧部。所述弹性隔膜309既起到了密封水位检测装置的作用，又起到了密封阀塞和排水口的作用。
活塞杆302与驱动电机316连接，驱动电机316驱动活塞杆302的往复运动。或者所述活塞杆302为中空结构，朝向阀塞301的一端为封闭端，活塞杆302内部设置第一弹簧313，所述第一弹簧313一端与封闭端连接，另一端与驱动电机313连接，驱动电机313驱动第一弹簧313，第一弹簧313带动活塞杆302往复运动，避免驱动电机316直接与刚性活塞杆302连接对驱动电机316产生冲击。
排水控制机构300安装在洗衣机外桶底部，所述阀塞301连接一波纹管303，波纹管303一端与阀塞301连接，另一端与外桶底部连接，优选所述阀塞301和所述波纹管303一体成型，波纹管303有一定的伸缩性，能使活塞杆302有一定的往复活动范围的时候始终保持外桶的密封。
活塞杆302外设有第二弹簧314，第二弹簧314的一端与阀塞301相抵，另一端固定，所述第二弹簧314能在阀塞301向上运动时提供一定的推动力，所述排水控制机构300还包括阀座315，所述阀座315为排水控制结构300的安装座，安装在外桶200底部的外侧，阀座315中部设有活塞杆302的滑道，所述活塞杆302外设有第二弹簧314，第二弹簧314的一端与阀塞301相抵，另一端与阀座312相抵，阀塞301向下运动时，第二弹簧314被压缩，阀塞301向上运动时第二弹簧314恢复，阀塞301向上运动时第二弹簧314能提供一定的推动力。
以上所述仅为本发明的优选实施方式，应当指出，对于本领域的普通技术人员而言，在不脱离本发明原理前提下，还可以做出多种变形和改进，这也应该视为本发明的保护范围。
