具体实施方式
现在将详细参照本发明的优选实施例,其示例表示于附图中。
下面将对依照本发明的滚筒式洗衣机的蒸汽发生器进行说明。
图2是显示依照本发明的滚筒式洗衣机的透视图。
如图所示,滚筒式洗衣机100包括:形成其外观的机壳101;设置于机壳101内用来贮存洗涤用水的洗衣桶102;可旋转地设置于洗衣桶102内用来清洗和甩干衣物的滚筒103;设置于机壳101一侧用来使滚筒102旋转的驱动电机(未示出);设置于机壳101一侧用来产生蒸汽的蒸汽发生器200;设置于滚筒103上侧用来把蒸汽发生器200所产生的蒸汽提供到滚筒103的歧管105;用来连接蒸汽发生器200与歧管105的第一连接软管106;设置于滚筒103下侧用来排放滚筒103内的洗涤用水的排水管107;用来连接排水管107与歧管105的第二连接软管108;以及设置于第二连接软管108与排水管107之间用来使滚筒103排出的洗涤用水循环进入歧管105的循环泵109。用高压来喷放蒸汽的喷嘴105a形成于歧管的一端,洗衣粉盒B设置于机壳101的上部。
第一给水管101a连接于蒸汽发生器200,第二给水管101b连接于洗衣粉盒B。
图3是依照本发明的一个实施例的滚筒式洗衣机的蒸汽发生器的透视图,图4是图3的截面透视图。
如图所示,依照本发明的一个实施例的蒸汽发生器包括:具有一个空间部分用来在其中贮存水的容器,在其一侧是用来给水的给水部分,在其另一侧是用来排放蒸汽的蒸汽排放部分;设置于容器上用来检测容器内贮水水位的水位检测装置;以及设置于容器内用来对容器内贮水进行加热的加热器。
依照本发明的滚筒式洗衣机的蒸汽发生器包括:具有一个空间部分S用来在其中贮存水的容器210,在其一侧是用来给水的给水部分211a,在其另一侧是用来排放蒸汽的蒸汽排放部分212a;设置于容器210上用来检测容器210内贮水水位的水位检测传感器220;以及设置于容器210内用来对容器210内贮水进行加热的加热器230。
容器210由安置有加热器230的下容器211、连接于下容器211的上容器212、介于下容器211和上容器212之间的水密构件213以及用来连接下容器211和上容器212的容器连接装置组成。
容器连接装置由形成于下容器211的外圆周表面并具有多个螺栓孔H的下凸缘部分214a,形成于上容器212的外圆周表面并具有多个螺栓孔H的上凸缘部分214b和接合于螺栓孔H的螺栓214c组成。
下容器211和上容器212通过热接合或超声波接合方式相互连接在一起。
加热器230由设置于下容器211底面的传热管231和设置于传热管231两端来连接外部电源(未示出)的连接器232组成。
用来贮存加热器230所产生的蒸汽的蒸汽储槽211b设置在相应于上容器212内表面处的蒸汽排放部分212a的位置。
用来阻止下和上容器211和212内的水进入蒸汽排放部分212a的隔板215形成于上容器212的内表面,并且有多个狭缝215a沿纵向形成于隔板上。
水位检测传感器220由连接于上容器212上部的主体221、三个沿纵向按120°设置于主体221的检测棒222、223和224、以及设置于主体221下部用来遮蔽检测棒222、223和224的带有纵向狭缝225a的隔板225组成。
当用高压将贮存于蒸汽储槽211b内的蒸汽通过蒸汽排放部分212a排放时产生振动,容器211和212内的水面会随着颤动,所以水位检测传感器220不能精确地测量水位。因此,优选地水位检测传感器220和蒸汽排放部分212a要尽可能彼此分开设置。
假定检测棒222、223和224中最长的是第一检测棒222,中长的是第二检测棒223而最短的是第三检测棒224。
据此,容器211和212内的给水时间点和加热器230的开动时间点由第一和第三检测棒222和224来检测,而加热器230的关闭时间点由第一和第二检测棒222和223来检测。
用于由螺栓将容器211和212接合到机壳101的安装托架216形成于容器211和212的一侧。
图7是依照本发明的第二实施例的滚筒式洗衣机的蒸汽发生器的纵截面图。
如图所示,依照本发明的另一实施例的滚筒式洗衣机的蒸汽发生器包括:具有一个空间部分S用来在其中贮存水的容器310,在其上部的一侧是用来给水的给水部分311a,在其上部的另一侧是用来贮存蒸汽的蒸汽贮存部分311b,在蒸汽贮存部分311b处还有用来排放蒸汽的蒸汽排放部分311c;设置于容器310上用来检测容器310内贮水水位的水位检测传感器(未示出);设置于容器310内用来对容器310内贮水进行加热的加热器330;以及形成于容器310内部上表面的隔板340。
容器310由下容器311和上容器312以及将加热器330所产生的蒸汽引入蒸汽贮存部分311b的隔板组成。
下面,将参照图2对依照本发明的具有蒸汽发生器的滚筒式洗衣机进行说明。
使用者把衣物放入滚筒103并打开电源,设置于机壳101内的传感器(未示出)对衣物数量进行检测,然后打开第二给水管101b从而把水供入洗衣桶102。
同时,驱动电机(未示出)开始运转从而使滚筒103旋转,循环泵109通过排水管107、第二连接软管108和歧管105将水循环一段预定时间来溶解洗衣粉。
水循环之后,蒸汽发生器200开始运转从而通过第一连接软管106和歧管105来给滚筒103提供蒸汽,将所供给的蒸汽通过喷嘴105a用高压喷射到滚筒103内。用高压喷射蒸汽可以消除衣物上的细菌。
即使在执行水循环时,使用者也可以选择来操作蒸汽发生器200。通过蒸汽发生器200的工作,蒸汽被通过第一连接软管106和歧管105供给。这时,通过第二连接软管108引入歧管105的洗涤用水连同所供给的蒸汽通过循环泵109被高压喷射到滚筒103内。因此当把带有蒸汽的洗涤用水用高压喷射到滚筒103后,即使用少量的水也能容易地浸透衣物从而来增加洗涤功效。
下面,将参照图3到6对滚筒式洗衣机的蒸汽发生器的操作进行说明。
水一直贮存于容器210内,而通过加热器230把水转化为蒸汽后就贮存在蒸汽贮存部分211b内。当所贮蒸汽达到或超过一定压力时,就通过蒸汽排放部分212a将其排放到容器210外。
如图6中所示,水位检测传感器222的检测棒由第一检测棒222,第二检测棒223和第三检测棒224组成。容器210内的给水时间点和加热器230的开动时间点(驱动时间点)由第一和第三检测棒222和224来检测,而加热器230的关闭时间点(停止驱动时间点)由第一和第二检测棒222和223来检测。
也就是说,只有当水位达到h1时才给水到容器210内,随后,就隔断给水。在此情形下水一直贮存在容器210内,当使用者选定一个蒸汽使用模式按钮时,蒸汽发生器的加热器230开始加热从而将水转化为蒸汽。
这时,加热器230不断运转一直到水位变为h2,随后,就自动停止给水。
重复执行上述的系列操作从而自动给水到容器210或自动隔断,而加热器230自动运转从而来产生蒸汽。
如上所述,在本发明中,利用蒸汽发生器所产生的蒸汽可以消除衣物上的细菌,并且利用蒸汽的喷压可以使溶解了洗衣粉的洗涤用水很快浸透衣物,因此用少量的水就可以有效地清洗衣物。
由于可以以各种形式来实施本发明而不脱离其实质或本质特征,而且还应当理解,除非另有说明,上述实施例并不局限于以上说明的任何细节,而是可以在由所附权利要求书限定的实质和范围内宽泛构造,因此所有落入权利要求书的范围或者这些范围的等同体内的变化和修改都包含于所附权利要求书内。
