Description

洗衣机 技术领域
本发明涉及一种洗衣机。
背景技术
以往，已知能对洗涤物实施抗菌处理的洗衣机。例如，在以下的专利文献1中记载了一种洗衣机，其具备离子溶出单元，由洗涤筒来承接含有从该离子溶出单元溶出的金属离子的水，通过用该水漂洗洗涤物来对洗涤物进行抗菌处理。
作为衣物可能受到的伤害，除了细菌的繁殖以外，还考虑衣物害虫的虫蛀。因此，在将季节性的衣物收纳进衣橱、衣柜等收纳库时，多会在收纳库内放入市售的防虫剂以便不滋生衣物害虫。
若能通过在洗衣机中对衣物实施防虫处理来使收纳前的衣物具有防虫效果，则收纳中的衣物不容易滋生衣物害虫，非常便利。

图3是表示滚筒洗衣机1的结构的框图。
滚筒洗衣机1除了上述结构以外，还具备：控制部401、存储部402、操作 部403、显示部404、水位检测部405、门传感器406、温度传感器407、马达驱动部408、供水驱动部409、排水驱动部410、泵驱动部411、风扇驱动部412以及压缩机驱动部413。

显示部404包括LED等发光元件、液晶面板等显示器，根据来自控制部401的控制信号，进行所选择的模式的显示、运转的进行状况的显示、异常的通知等。
水位检测部405检测外筒20内的水位，并将与水位对应的水位信号输出至控制部401。门传感器406检测门12的开闭，并将与门12的开闭对应的检测信号输出至控制部401。温度传感器407检测外筒20内的温度，并将与温度对应的温度信号输出至控制部401。
马达驱动部408根据来自控制部401的控制信号对驱动马达30进行驱动。马达驱动部408包括检测驱动马达30的转速的旋转传感器、逆变电路等，调整驱动电力使得驱动马达30以由控制部401设定的转速进行旋转。
供水驱动部409根据来自控制部401的控制信号驱动供水阀110的第一阀111和第二阀112。排水驱动部410根据来自控制部401的控制信号驱动排水阀41。泵驱动部411根据来自控制部401的控制信号驱动雾喷器机构230的泵232。

存储部402包括EEPROM(电可擦可编程只读存储器)、RAM(随机存取存储器)等。存储部402中存储有用于执行各种模式的运转的程序。此外，存储部402中存储有用于执行这些程序的各种参数、各种控制标记。
控制部401包括CPU(中央处理器)等，基于来自操作部403、水位检测部405、门传感器406、温度传感器407等的各信号，并根据存储于存储部402 的程序来控制显示部404、马达驱动部408、供水驱动部409、排水驱动部410、泵驱动部411、风扇驱动部412、压缩机驱动部413等。
进而，在滚筒洗衣机1中，基于用户对操作部403的操作，在控制部401的控制下进行各种运转模式的洗涤烘干运转、洗涤运转或烘干运转。在洗涤烘干运转中，依次进行清洗过程、中间脱水过程、漂洗过程、最终脱水过程以及烘干过程。在洗涤运转中，从清洗过程进行到最终脱水过程而不进行烘干过程。在烘干运转中，仅进行烘干过程。根据运转模式，有时会进行两次以上的漂洗过程和中间脱水过程。
在清洗过程中，向外筒20内蓄留含洗涤剂的水至与容纳于滚筒23内的洗涤物的负荷量对应的清洗水位，通过反复进行滚筒23的正转和反转，浸泡于该水中的洗涤物被翻滚。含洗涤剂的水浸透至洗涤物的内部，通过洗涤剂的效力和由翻滚产生的机械力，附着于洗涤物的表面、内部的污垢被去除。
在漂洗过程中，在外筒20内蓄水至漂洗水位的状态下，滚筒23进行正转和反转，洗涤物被翻滚。由此，洗涤物中所含的洗涤剂与水一同被排出，洗涤物被漂洗。
在清洗过程和漂洗过程的供水时，通过供水装置50来进行经过注水口构件140向外筒20内的供水和经过喷淋喷嘴170向外筒20内的供水。此外，在清洗过程中，通过供水装置50来进行供水的同时进行洗涤剂的自动投入，在漂洗过程中，通过供水装置50来进行供水的同时进行柔顺剂的自动投入。在进行两次以上漂洗过程的情况下，在最后的漂洗过程中投入柔顺剂。
在中间脱水过程和最终脱水过程中，驱动马达30单向高速旋转，滚筒23以作用于滚筒23内的洗涤物的离心力远大于重力的转速单向旋转。通过离心力的作用，洗涤物被按压在滚筒23的内周面上而被脱水。在最终脱水过程中，滚筒23以比中间脱水过程中的转速高的转速旋转。
在烘干过程中，通过鼓风扇320的工作，空气在外筒20与循环路310之间循环，通过第二热交换器340的工作，导入至外筒20的空气被加热而成为热风。而且，滚筒23进行正转和反转，洗涤物被翻滚。
从导入口24b被导入至外筒20和滚筒23内的暖风与翻滚的洗涤物接触来 烘干洗涤物。从洗涤物中剥离了水分的暖风从排气口20c向循环路310返回。在循环路310内的暖风在被第二热交换器340加热前经过第一热交换器330而被第一热交换器330除湿。
在滚筒洗衣机1中，可以进行对上衣、毛衣等衣物实施防虫处理的防虫处理运转。而且，可以进行对通过烘干过程而被烘干的衣物实施防虫处理的洗涤烘干运转和烘干运转。在滚筒洗衣机1中，作为运转模式准备了：防虫处理模式，进行防虫处理运转；防虫洗涤烘干模式，进行附带防虫处理的洗涤烘干运转；以及防虫烘干模式，进行附带防虫处理的烘干运转。
图4是表示防虫处理运转中执行的控制部401的控制动作的流程图。图5的(a)至(c)是用于对防虫处理运转进行说明的图。
在进行防虫处理运转的情况下，用户将作为防虫处理的对象的衣物投入至滚筒23内。此外，如图5的(a)所示，用户向防虫剂投入器210内投入预先指定的量的防虫剂。然后，用户在操作部403中通过模式选择按钮来选择防虫处理模式并按下开始按钮。由此，防虫处理运转开始。
参照图4，当防虫处理运转开始时，首先，控制部401执行准备过程(S1)。
在准备过程中，控制部401使驱动马达30工作来使滚筒23以作用于该滚筒23内的衣物的离心力比重力小的转速旋转，并且使鼓风扇320旋转。滚筒23既可以仅单向旋转，也可以正反方向反转旋转。
通过滚筒23的旋转，衣物在滚筒23内翻滚。通过衣物落至滚筒23的底部时的冲击，附着于衣物的表面的线屑、尘埃被去除。在衣物上附有衣物害虫的情况下，还能够去除衣物害虫。
通过鼓风扇320的旋转，空气即风在外筒20与循环路310之间循环。从衣物中去除的尘埃等异物漂浮在空气中，随着循环风的流动而从滚筒23的脱水孔23b向外筒20内排出，并从排气口20c被导入至循环路310内。导入至循环路310内的异物由烘干过滤器350回收。
当经过规定时间时，控制部401使滚筒23和鼓风扇320停止。由此，准备过程结束。
接着，控制部401执行防虫液生成过程(S2)。
在防虫液生成过程中，控制部401使供水阀110的第二阀112打开。如图5的(b)所示，经由第二供水软管130向防虫剂投入器210内供给水。防虫剂投入器210内的防虫剂被所供给的水冲走而从防虫剂投入器210排出，与水一同流向贮液盒220。由此，贮液盒220内贮留有通过防虫剂与水的混合而生成的防虫液。
当从打开第二阀112起经过规定的供水时间来向贮液盒220内贮留了规定量的防虫液时，控制部401关闭第二阀112。由此，防虫液生成过程结束。
需要说明的是，控制部401也可以将防虫液生成过程与准备过程并行地执行。在该情况下，能缩短防虫处理运转的所需时间。
接着，控制部401执行防虫处理过程(S3)。
在防虫处理过程中，控制部401使喷雾机构230的泵232工作。如图5的(c)所示，贮液盒220内的防虫液通过泵232的工作而被送向喷雾喷嘴231，从喷雾喷嘴231被喷雾向滚筒23内的衣物。由此，衣物的表面附着防虫剂的防虫成分。
而且，在防虫处理过程中，控制部401使驱动马达30工作来使滚筒23以作用于该滚筒23内的衣物的离心力比重力小的转速旋转。由此，衣物在滚筒23内翻滚，喷雾出的防虫液容易均匀地沾在衣物的表面，防虫成分容易附着在衣物的整个表面。
当经过规定的喷雾时间时，控制部401使泵232和滚筒23停止。由此，防虫处理过程结束。
接着，控制部401使显示部404、未图示的扬声器进行催促从滚筒23取出衣物的通知(S4)。然后，控制部401检测是否已从滚筒23内取出衣物(S5)。在从滚筒23内取出衣物的情况下，门12打开。因此，当通过门传感器406检测到门12的打开并在之后检测到门12的关闭时，控制部401判定衣物已被取出。
需要说明的是，也可以是，控制部401使滚筒23旋转，通过施加于驱动马达30的负荷来检测滚筒23内的洗涤物的负荷量，并通过未检测到负荷量来判定衣物已被取出。
当判定衣物已被取出时(S5：是)，控制部401执行清扫过程(S6)。
在清扫过程中，控制部401打开供水阀110的第一阀111，向外筒20内进行供水至滚筒23的底部浸于水中的水位。然后，控制部401使滚筒23旋转规定的洗净时间。滚筒23被外筒20内的水洗净，附着于滚筒23的内周面的防虫剂的防虫成分被去除。
接着，控制部401打开排水阀41来从外筒20内进行排水。之后，控制部401使滚筒23比上述的洗净高速旋转，按规定的脱水时间进行滚筒23的脱水。当脱水完成时，清扫过程结束。
如此，防虫处理运转结束。
图6是表示附带防虫处理的洗涤烘干运转中执行的控制部401的控制动作的流程图。
在进行附带防虫处理的洗涤烘干运转的情况下，用户将衣物投入至滚筒23内并且将防虫剂投入至防虫剂投入器210内。然后，用户在操作部403中通过模式选择按钮来选择防虫洗涤烘干模式并按下开始按钮。由此，洗涤烘干运转开始。
参照图6，控制部401依次执行清洗过程、中间脱水过程、漂洗过程、最终脱水过程以及烘干过程(S11～S15)。
接着，控制部401执行送风过程(S16)。
在送风过程中，控制部401不使第二热交换器340工作而使鼓风扇320旋转。而且，控制部401以衣物会翻滚的方式使滚筒23旋转。向外筒20内即滚筒23内导入冷风，滚筒23内和衣物被冷却。
当由温度传感器407检测到的外筒20内的温度降低至规定温度例如40℃时，控制部401使鼓风扇320和滚筒23停止。由此，送风过程结束。
接着，控制部401执行防虫液生成过程和防虫处理过程(S17、S18)。由此，对滚筒23内的衣物实施防虫处理，衣物上附着防虫成分。此时，滚筒23内和衣物的温度低，因此防虫成分不易受热的影响。
之后，当基于催促取出衣物的通知而从滚筒23内取出了衣物时(S19、S20： 是)，控制部401执行清扫过程(S21)。由此，滚筒23被洗净。
如此，当清扫过程完成时，洗涤烘干运转结束。
需要说明的是，也可以是，控制部401将防虫液生成过程与送风过程并行地执行。在该情况下，能缩短洗涤烘干运转的所需时间。
在用户选择防虫烘干模式并执行了附带防虫处理的烘干运转的情况下，由控制部401执行从图6所示的洗涤烘干运转中的步骤S15的烘干过程到步骤S21的清扫过程。
需要说明的是，在本实施的滚筒洗衣机1中，也可以在烘干装置60中设置自动清扫烘干过滤器350的自动清扫装置。在该情况下，烘干过滤器350纵向配置即可。自动清扫装置例如包括：刮拭机构，具有擦拭烘干过滤器350的捕获面的刮拭件；以及供水机构，使水流过烘干过滤器350的捕获面。通过用刮拭件擦拭烘干过滤器350的捕获面或使水流过捕获面，附着于捕获面的尘埃等异物被去除。例如，在洗涤烘干运转、防虫处理运转结束后，可以进行使自动清扫装置工作的过滤器清扫运转。

根据这样的结构，能在防虫处理过程之前使附着于滚筒23内的衣物的尘埃等异物脱落，因此能不受异物妨碍地使防虫成分作用于衣物。此外，在衣物上附着有衣物害虫的情况下，能将该衣物害虫从衣物去除。
而且，根据本实施方式，滚筒洗衣机1采用如下结构：控制部401执行通过烘干装置60来烘干滚筒23内的衣物的烘干过程，并在该烘干过程之后执行防虫处理过程。
根据该结构，能使通过烘干过程而被烘干的衣物保持防虫效果。
而且，根据本实施方式，滚筒洗衣机1采用如下结构：在烘干过程与防虫处理过程之间，控制部401执行通过烘干装置60将未被第二热交换器340加热的风供给至滚筒23内来将滚筒23内冷却的送风过程。
根据该结构，能使防虫成分作用于在送风过程中被冷却的衣物，因此防虫成分不易受热的影响。
＜实施方式2＞
对实施方式2的滚筒洗衣机2进行说明。
图7是表示滚筒洗衣机2的结构的侧面剖视图。图8的(a)和(b)是表示烘干装置60和防虫处理装置80的结构的滚筒洗衣机2的主要部分的侧面剖视图。图8的(a)示出通过风路切换器90来使防虫剂风路510关闭而第二管道313打开的状态，图8的(b)示出通过风路切换器90来使第二管道313关闭而防虫剂风路510打开的状态。需要说明的是，在图8的(a)和(b)中，将防虫剂管道511、防虫剂容器520、风扇壳体312以及第二管道313描绘为剖视图。
在本实施方式中，滚筒洗衣机2具备防虫处理装置80来取代上述实施方式1的防虫处理装置70。防虫处理装置80相当于本发明的防虫处理部。
而且，滚筒洗衣机2的供水阀单元51具备仅包括一个阀110a的供水阀110A和第一供水软管120。
防虫处理装置80包括：鼓风扇320；防虫剂风路510，与外筒20相连，从循环路310中的第一热交换器330和第二热交换器340与鼓风扇320之间的位置即第二管道313的入口附近部分分支；以及防虫剂容器520，配置于该防虫剂风路510内，容纳防虫剂。防虫剂容器520相当于本发明的容纳部。
防虫剂风路510由防虫剂管道511和导入管道512构成，导入管道512连接于形成于衬垫24的上部的防虫剂导入口24c。
防虫剂容器520包括：容器主体521，其上表面开口；以及盖522，阻塞容器主体521的上表面的开口。防虫剂容器520中容纳有能在常温下气化的防虫剂。防虫剂既可以使用能在常温下升华的固体防虫剂，也可以使用具有挥发性的液体防虫剂。在使用液体防虫剂的情况下，该防虫剂被放入会以不会漏出的方式放出气化的防虫成分的容器，被容纳于防虫剂容器520。
防虫剂容器520经过设于箱体10的顶面和防虫剂管道511的顶面的投入口15而插入至防虫剂管道511内。在防虫剂容器520中，在面朝风流动的方向的容器主体521的前表面和后表面形成有供风通过的多个通气孔523。
在第二管道313内，在第一热交换器330的上游设有将该第二管道313内分隔开的分隔壁316。在分割壁316形成有连通口316a。
在第二管道313的入口附近部分设有风路切换器90。风路切换器90由风门(flap)91和驱动风门91的致动器92构成。通过被致动器92驱动，风门91在阻塞防虫剂管道511的入口511a的位置与阻塞分隔壁316的连通口316a的位置之间转动。风路切换器90相当于本发明的切换部。
如图8的(a)所示，当防虫剂管道511的入口511a被风门91阻塞时，成为防虫剂风路510关闭且第二管道313打开的状态。
如图8的(b)所示，当分隔壁316的连通口316a被风门91阻塞时，成为第二管道313关闭且防虫剂风路510打开的状态。
图9是表示滚筒洗衣机2的结构的框图。
滚筒洗衣机2具备致动器驱动部414来取代上述实施方式1的泵驱动部411。致动器驱动部414根据来自控制部401的控制信号来驱动致动器92。
本实施方式的滚筒洗衣机2中也能进行防虫处理运转和附带防虫处理的洗涤烘干运转。
图10的(a)是表示防虫处理运转中执行的控制部401的控制动作的流程图。图10的(b)是表示附带防虫处理的洗涤烘干运转中执行的控制部401的控制动作的流程图。
在本实施方式的防虫处理运转和洗涤烘干运转中，不存在防虫液生成过程。
此外，在防虫处理运转的准备过程、洗涤烘干运转的烘干过程以及送风过程中，如图8的(a)所示，控制部401通过风路切换器90切换为防虫剂风路510关闭且第二管道313打开的状态。如图8的(a)的箭头所示，在准备过程和送风过程中，冷风在外筒20与循环路310之间循环，在烘干过程中，暖风在外筒20与循环路310之间循环。
而且，在防虫处理运转和洗涤烘干运转中的防虫处理过程中，控制部401通过风路切换器90切换为第二管道313关闭且防虫剂风路510打开的状态。然后，控制部401使鼓风扇320旋转。而且，控制部401以该滚筒23内的衣物会翻滚的方式使滚筒23旋转。
如图8的(b)的箭头所示，由鼓风扇320的旋转产生的风流过防虫剂风路 510，经过防虫剂容器520。在防虫剂容器520内由防虫剂气化即挥发或者升华而成的防虫成分被风运送，经过防虫剂导入口24c被导入至外筒20内即滚筒23内。由此，滚筒23内的衣物上附着防虫成分。此时，衣物在滚筒23内翻滚，因此防虫成分容易附着于整个衣物。
＜实施方式2的效果＞
根据本实施方式，滚筒洗衣机2具备使防虫剂的防虫成分作用于容纳于滚筒23内的衣物的防虫处理装置80。由此，能使衣物具有防虫效果，因此在该衣物被收纳于衣橱、衣柜等收纳库时，收纳库内的该衣物不容易滋生衣物害虫。
而且，根据本实施方式，滚筒洗衣机2采用如下结构。即，防虫处理装置80包括：鼓风扇320；防虫剂风路510，供由鼓风扇320的旋转产生的风流向滚筒23内；以及防虫剂容器520，配置于防虫剂风路510内，容纳防虫剂，气化的防虫成分由流过防虫剂风路510的风运送至滚筒23内。
根据该结构，能使由防虫剂气化出的防虫成分作用于滚筒23内的衣物。
而且，根据本实施方式，采用如下结构：滚筒洗衣机2还具备风路切换器90，防虫剂风路510从循环路310中的第二热交换器340与鼓风扇320之间的位置分支，在通过由第二热交换器340加热过的风来烘干滚筒23内的衣物时，风路切换器90关闭防虫剂风路510并且打开第二管道313，在通过防虫处理装置80来使防虫成分作用于滚筒23内的衣物时，风路切换器90打开防虫剂风路510并且关闭第二管道313。
根据该结构，通过在防虫剂风路510关闭的状态下使第二热交换器340和鼓风扇320工作来将暖风供给至滚筒23内，能烘干滚筒23内的衣物。此时，暖风不与防虫剂容器520内的防虫剂接触，因此防虫剂不易暴露于热中。而且，通过在防虫剂风路510打开的状态下使鼓风扇320工作，能使由防虫剂容器520内的防虫剂气化出的防虫成分作用于滚筒23内的衣物。
此外，根据本实施方式，能通过与上述实施方式1同样的结构来发挥与上述实施方式1同样的效果。
＜变更例＞
以上，对本发明的实施方式进行了说明，但本发明并不受上述实施方式等 的任何限制，此外，本发明的实施方式也可以在上述内容以外进行各种变更。
例如，在上述实施方式1中，防虫处理装置70具有防虫剂投入器210。然而，防虫处理装置70也可以不具有防虫剂投入器210并向贮液盒220内直接投入防虫剂并且从供水阀单元51供给水。在该情况下，在贮液盒220，在其上部形成有由盖开闭的投入口，该投入口配置于箱体10的顶面、前表面。
而且，在上述实施方式1中，通过将防虫剂与从供水阀单元51供给的水混合来生成防虫液并将其贮留于贮液盒220中。然而，也可以采用液体防虫剂不被水稀释而贮留于贮液盒220的结构。
而且，在上述实施方式1中，采用如下结构：喷雾机构230具备喷雾喷嘴231和泵232。然而，喷雾机构230的结构不限于上述结构，例如可以是如下结构：喷雾机构230具备具有超声波振子的雾化喷嘴而不具备泵，将从贮液盒220向雾化喷嘴通过自重输送来的防虫液在雾化喷嘴中通过超声波振动进行雾化并喷雾至滚筒23内。
而且，在上述实施方式1中，在清扫过程中，通过在外筒20内蓄有水的状态下使滚筒23旋转来去除附着于滚筒23的防虫液。然而，也可以设为：在清扫过程中，从烘干装置60向滚筒23内供给暖风，通过暖风来使附着于滚筒23的防虫液蒸发而从滚筒23去除该防虫液。
而且，在上述实施方式2中，采用如下结构：防虫剂风路510从循环路310的中途分支，并且循环路310中设有风路切换器90，由此防虫处理装置80和烘干装置60共用鼓风扇320。然而，防虫处理装置80也可以采用如下的独立于烘干装置60的结构：防虫剂风路510不从循环路310分支，从与鼓风扇320不同的鼓风扇向防虫剂风路510送风。
而且，在上述实施方式2中，使用了会挥发即常温下会气化的液体防虫剂或常温下会升华的固体防虫剂。然而，也可以使用在比常温高的温度下气化的液体防虫剂或在比常温高的温度下升华的固体防虫剂。
而且，在上述实施方式1、实施方式2中，在防虫处理运转和附带防虫处理的洗涤烘干运转中，在防虫处理过程之后执行清扫过程，但也可以设为这些运转不包括清扫过程。
而且，在上述实施方式1、实施方式2中，在防虫处理运转中，在防虫处理过程之前执行准备过程，但也可以设为防虫处理运转不包括准备过程。
而且，在上述实施方式1、实施方式2中，示出了滚筒洗衣机1、滚筒洗衣机2。然而，本发明也能应用于滚筒洗衣机1、滚筒洗衣机2以外的洗衣机，例如能应用于在外桶内具有纵轴型的洗涤脱水桶的全自动洗衣机。全自动洗衣机可以是具有烘干功能的全自动洗干一体机。
除此之外，本发明的实施方式能在技术方案所示出的技术思想的范围内适当地进行各种变更。
