Description

一种桶间无水洗衣机及控制方法 技术领域
本发明涉及洗衣机领域，尤其是一种桶间无水洗衣机及控制方法。
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。
200420107890.8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孔；盛水桶上开有与排水管相通的第一排水孔，排水管上设有排水阀。盛水桶通过吊杆与箱体固定连接。吊杆的一端与箱体上端的内壁相连接，另一端与盛水桶的外壁相连接。但是长时间运转，因为密封结构长时间运转磨损，容易造成磨损漏水，如果水质较差，含沙量较高，使用寿命会大大缩短，就不能起到应有的功能了。也不适应洗涤容量大的状态下使用，可靠性较差。
鉴于此提出本发明。
发明内容

优选所述弹性管道为软管或者波纹管。
所述伸缩式排水阀至少包括一可伸缩的阀塞，所述阀塞包括一可伸缩的阀杆和一套设在阀杆上可随阀杆的伸缩而伸缩的弹性密封套，所述阀杆的中心为中空结构，上部设有进水口，下部设有出水口，进水口处设置压盖，所述密封套的上部延伸至进水口内，所述压盖与阀杆连接并将所述密封套挤压至压盖与所述阀杆之间，压盖的顶部为镂空结构，
优选所述压盖的顶部的为格栅结构，格栅的间隙形成透水孔。
所述压盖的顶部向上凸起，为中间高周围低的半球形弧面。
所述伸缩式排水阀封堵内桶排水口时，所述压盖顶部高出内桶底，所述伸缩式排水阀打开内桶排水口时，所述压盖顶部高出外桶底。

如图1、图2所示，本发明所述一种桶间无水洗衣机，包括内桶1、外桶4、内桶1的上部靠近上缘设有多个甩水孔2，内桶1的底部设有至少一个内桶排水口3，外桶4底部设有能封堵内桶排水口的伸缩式排水阀10，外桶4底部设有外桶排水口5，所述外桶排水口5设有洗衣机排水管路6。
洗涤时，内桶1被锁定，伸缩式排水阀10封堵内桶排水口3，内桶1中有水，内外桶之间无水，排水时，伸缩式排水阀10打开内桶排水口，内桶1内大部分水从内桶排水口3排出内桶1，再通过外桶排水口5及洗衣机排水管路6排出，脱水时，内桶1解除锁定，内桶1旋转脱水，脱水时甩出的水受离心力的作用向上运动，通过甩水孔2排出内桶，至内桶、外桶之间，再通过外桶排水口5及洗衣机排水管路6排出。
所述外桶4和所述内桶1同心设置，内桶排水口3中心距内桶1中心的距离与外桶排水口5中心距外桶4中心的距离相同，内桶排水时，内桶排水口3正对外桶排水口5，水流从内桶1中出来直接通过外桶排水口5进入洗衣机排水管路6排出，排水顺畅，在内外桶间停留的时间短，不需要水先排至内外桶之间，在流至外桶排水口5，优选所述外桶排水，5直径大于所述内桶排水口3直径，避免水流在内外桶之间停留，避免污垢沾在外桶内壁上。
上述洗衣机洗涤时，内外桶之间无水，可节省洗涤用水，每次洗涤大概节省20％左右，排水时，大部分水通过下部排水口排出，线屑、泥沙随之排出，不会在内桶内堆积，同时脱水和洗涤时，内桶和封堵内桶排水口的密封结构(伸缩式排水阀)之间无相对运动，避免磨损。
所述外桶4上设置气室7，所述气室7设置在外桶4的内部或外部均可，本发明中优选气室7设置在外桶4的外部，不会影响内桶1的安装，使内桶1容量尽可能增大，所述气室7与内桶通过第二管路连通，内桶1中有水时，水可进入气室，气室7上连接有压力传感器19，通过压力传感器19检测气室7内的空气压力检测内桶中的水位。该种检测方法检测水位，结构简单，检测结果准确。
如图3图4所示，本发明中气室7和内桶1通过伸缩式排水阀10连通，所述伸缩式排水阀10为中空结构，上部设有进水口12，下部设有出水口13，所述出水口13与气室7之间通过弹性管道14连接，伸缩式排水阀10封堵内桶排水口3时，内桶1中的水不能进入内桶1和外桶4之间，但是可以通过伸缩式排水阀10内部中空结构进入气室7，压缩气室内的气体，压力传感器19检测气室7内的空气压力从而得出内桶的水位， 实现对水位的检测和控制，由于伸缩式排水阀上下往复伸缩，下部出水口是运动的，出水口与气室之间设置弹性管道14可以实现固定的气室7和运动的下部出水口之间的连接。优选所述弹性管道14为软管或者波纹管。所述第二管路包括伸缩式排水阀的中空部分和所述弹性管道。
如图5、图6所示，所述伸缩式排水阀10至少包括一可伸缩的阀塞，所述阀塞包括一可伸缩的阀杆15和一套设在阀杆15上可随阀杆15的伸缩而伸缩的弹性密封套16，所述阀杆15的中心为中空结构，上部设有进水口12，下部设有出水口13，进水口12处设置压盖17，所述密封套16的上部延伸至进水口12内，所述压盖17与阀杆15连接并将所述密封套16挤压至压盖17与所述阀杆15之间，下部出水口处设置软管或波纹管连接至气室。所述第二管路包括伸缩式阀杆的中空部分和所述软管或波纹管。压盖17的顶部为镂空结构，内桶内的水可以通过所述镂空结构进入阀杆15内部，再流至气室7。
所述压盖17的顶部设有多个透水孔，或者压盖的顶部的为格栅结构，格栅的间隙形成透水孔。设置格栅可以阻挡线屑等异物进入气室。
压盖17的顶部向上凸起，为中间高周围低的半球形弧面。凸起结构和半球形弧面可避免线屑等异物在压盖上方停留、堆积堵塞压盖的透水孔。所述压盖17既能连接阀杆15和密封套16，还能起到防止线屑堆积的作用。
所述伸缩式排水阀10封堵内桶排水口3时，所述压盖17顶部高出内桶底，所述伸缩式排水阀打开内桶排水口3时，所述压盖17顶部高出外桶底。进一步避免线屑等异物在压盖上方停留、堆积堵塞压盖的透水孔。
所述密封套16位于压盖17的周围设有一圈弹性凸筋18，所述弹性凸筋18的直径大于所述内桶排水口3的直径。所述伸缩式排水阀10封堵内桶排水口3时，弹性凸筋18位于内桶排水口外周的内桶底部，并被挤压实现密封，所述压盖17伸入内桶排水口3，压盖17的顶部高出内桶底，所述伸缩式排水阀10打开内桶排水口3时，所述弹性凸筋18可阻挡线屑等异物被冲到压盖17的顶部，同时压盖顶部高出外桶底，避免线屑等异物在压盖上方停留、堆积堵塞压盖的透水孔。
所述伸缩式排水阀10固定在外桶4外侧的底部，向上伸出至内桶底部封堵内桶排水口3，所述弹性管道14设置在外桶4外侧的底部，分别与伸缩式排水阀10下部出水口和气室连接，而洗衣机内的水通过外桶排水口5排出，所以洗衣机排水时，气室7中的水不会完全排出，导致气室7中总有一部分残余水，长时间残留在气室内会造成细菌 滋生，本发明中气室7设有能将气室7中的水排出的气室排水口8，每次洗衣机排完水后，或者定期打开该气室排水口8将气室中的水排出，避免残留在气室内。优选气室排水口8位于气室的最底部，保证气室中的所有水排出气室，气室排水口8处设置控制阀11，洗衣机在进水和洗涤状态下该控制阀11是封闭的，当洗衣机排水完成后，或者定期打开该控制阀11，将气室中的水排出。
所述气室排水口8与洗衣机排水管路6连通将气室中的水通过洗衣机排水管路6排出，所述气室排水口8通过第一管路9与洗衣机排水管路6连通，所述第一管路9上设置能控制第一管路通断的控制阀11，第一管路9与洗衣机排水管路6通过三通接头连接。
所述控制阀11设有牵引电机，由牵引电机实现控制阀的开闭，所述牵引电机安装在外桶底部，或者所述控制阀与所述伸缩式排水阀10的牵引电机连接，即控制阀和伸缩式排水阀共用一个牵引电机，节省零部件数量，节约成本。
所述洗衣机洗涤时，锁定内桶，控制伸缩式排水阀封堵内桶排水口，洗衣机进水至内桶，内桶中的水进入气室，压缩气室中的空气，检测气室中的空气压力得出内桶水位；内桶1和外桶4之间无水，排水时，控制伸缩式排水阀打开内桶排水口，内桶的水排至外桶，优选控制伸缩式排水阀打开内桶排水口后，解除内桶锁定，控制内桶转动至内桶排水口正对外桶排水口，内桶1中的水大部分通过底部的内桶排水口3排出，脱水时，少部分通过上部的甩水孔2排出，排至内桶1和外桶4之间后，通过外桶排水口5及洗衣机排水管路6排出，气室7设置气室排水口8，气室排水口8设置第一管路9连接至洗衣机排水管路6，气室7中残余的水通过气室排水口8及第一管路9、洗衣机排水管路6排出。
气室7通过第二管路与内桶连通，内桶1中的水进入气室7，气室7上连接有压力传感器19，通过压力传感器19检测气室内的空气压力检测内桶中的水位。
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。
