Description

臭氧处理装置 技术领域
本发明涉及一种臭氧处理装置，其通过将臭氧与处理对象物接触，进行处理对象物的除臭、除菌等。作为这样的臭氧处理装置，能够例示出：除洗涤功能外，具有通过臭氧进行衣物的除臭、除菌等功能的洗衣机、除烘干功能外，具有通过臭氧进行衣物的除臭、除菌等功能的衣物烘干机、除清洗功能外，具有通过臭氧进行鞋的除臭、除菌等功能的鞋清洗机、通过臭氧进行西服的除臭、除菌等的西服干洗机等。
背景技术
以往，熟知以下的洗衣机，即具有臭氧产生装置，将通过该臭氧产生装置生成的臭氧供给收纳衣物的洗涤槽内，将臭氧与衣物接触进行衣物的除臭、除菌等的洗衣机(参照专利文献1)。
这样，在具备基于臭氧的除臭/除菌功能的洗衣机中，当结束衣物的除臭、除菌等并停止臭氧的产生时，门锁未解除，衣物保持原样放置一会。然后，残留的臭氧通过自己分解而消失，当洗涤槽内的臭氧浓度某种程度降低时，可以解除门锁取出衣物。
可知的是周围的温度越高越促进臭氧的分解，。因此，在这样的洗衣机中，为了缩短从停止臭氧的供给到能取出衣物的时间，在臭氧的产生停止后，可以采用通过加热器对洗涤槽内进行加热，促进洗涤槽内的臭氧的分解的结构。

发明内容
发明所要解决的问题
如上所述，在构成为通过加热器对洗涤槽内进行加热，促进臭氧的分解的情况下，易消耗比较大的电力。此外，这样的构成难以适用于除臭等的对象物 不耐热的情况。
因此，本申请的发明人考虑了代替加热而用其它的条件促进臭氧的分解的方法的结果是，发现了在停止臭氧的供给后，通过对洗涤槽内进行加湿来促进臭氧的分解。
本发明是基于以提高湿度的方式促进臭氧的分解的新见解而完成的发明，其目的在于，提供一种抑制耗电的同时，此外，即使在处理对象物不耐热的情况下，能缩短从停止臭氧的供给到能取出处理对象物的时间的臭氧处理装置。
用于解决问题的技术方案
本发明的主要方式所涉及的臭氧处理装置，具备：收纳部，收纳处理对象物，并且通过门的关闭几乎保持密闭状态；臭氧产生部，产生供给所述收纳部的臭氧；雾产生部，产生用于对所述收纳部进行加湿的雾；以及控制部，执行将臭氧供给所述收纳部的臭氧产生过程和在该臭氧产生过程后分解残留于所述收纳部的臭氧的臭氧分解过程。此处，所述控制部在所述臭氧产生过程中使所述臭氧产生部工作后，在所述臭氧分解过程中使所述雾产生部工作。
根据上述结构，在臭氧分解过程中对收纳室内供给雾，收纳室内被加湿。由此，为了促进残留于收纳室内的臭氧的分解，能缩短从停止臭氧的供给到处理对象物的取出为止的时间。并且，由于基于超声波加湿装置等的加湿所需要的耗电与基于加热器的加热所需要的耗电相比能变得更小，所以能抑制耗电的同时，能实现促进残留的臭氧的分解。此外，即使在处理对象物不耐热的情况下，也能实现促进残留的臭氧的分解。
本方式所涉及的臭氧处理装置可构成为，还具备：风产生部，在所述收纳部内产生风；以及孔部，设置于所述收纳部，并且能以在所述收纳部内产生的风的流动将雾排出到外部。在这种情况下，所述控制部在所述臭氧分解过程中停止所述雾产生部后使所述风产生部工作。
根据上述结构，用户在通过将雾排出到外部降低了收纳部内的湿度的状态下，能从收纳部取出处理对象物。因此，能防止用户把手放入湿度高的收纳部而觉得不舒服的情况。
在本方式所涉及的臭氧处理装置中，所述收纳部可以构成为，包括外槽和配置在该外槽内并且能以相对于水平轴或水平方向倾斜的倾斜轴为中心进行旋转的滚筒。
在作为这样的结构的情况下，所述控制部还可以构成为，通过来自所述雾产生部的雾对所述收纳部进行加湿时，使所述滚筒进行旋转。
作为这样的结构，通过在臭氧分解过程中使滚筒旋转，滚筒内被全部加湿。由此，能均匀地促进滚筒内的臭氧的分解。
在作为上述结构的情况下，臭氧处理装置还可以构成为，具备将选择是否使所述滚筒旋转的操作进行接受的旋转选择操作部。
作为这样的结构，在进行不希望通过滚筒的旋转被搅拌的处理对象物的除臭、除菌等的情况下，通过旋转选择操作部的操作，能使滚筒不旋转。由此，能防止通过滚筒的旋转对处理对象物产生损伤等的不好之处。
本方式所涉及的臭氧处理装置还可以构成为，具备加热所述收纳部的加热部。在这种情况下，所述控制部在所述臭氧分解过程中，使所述雾产生部与所述加热部一起工作。
根据上述结构，与只进行收纳部内的加湿的结构相比，由于很大地促进臭氧的分解，所以能缩短能取出处理对象物的时间。此外，与只进行收纳部内的加热的结构相比，由于也能缩短能取出处理对象物的时间，所以与只进行加热的结构相比，能抑制作为臭氧分解过程整体的耗电。
在作为上述结构的情况下，臭氧处理装置还可以构成为，具备将选择是否加热所述收容部的操作进行接受的加热选择操作部。
作为这样的结构，在进行不耐热的处理对象物的除臭、除菌等情况下，通过加热选择操作部的操作，由于能设定为对收纳部内不进行加热，所以能防止通过加热损伤不耐热的处理对象物的情况。
发明效果
根据本发明，能提供一种抑制耗电的同时，此外，即使在处理对象物不耐热的情况下，也能缩短从停止臭氧的供给到能取出处理对象物的时间的臭氧处理装置。

具体实施方式
以下，对作为本发明的臭氧处理装置的一实施方式的滚筒式洗衣烘干机1，参照附图进行说明。
图1是表示滚筒式洗衣烘干机1的结构的侧面剖视图。
滚筒式洗衣烘干机1具有构成外观的机壳10。机壳10的前表面10a从中央部向上部倾斜，在倾斜的面形成洗涤物的投入口11。投入口11由自由开闭的门12覆盖。
在机壳10内，外槽20由多个减振器21弹性地支承。在外槽20内配置有能旋转的滚筒22。本发明的收纳部由外槽20以及滚筒22构成。外槽20以及滚筒22相对于水平方向，以后表面侧变低的方式倾斜。由此，滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转。外槽20以及滚筒22的倾斜角度可以设为10～20度左右。外槽20的前表面的开口部20a以及滚筒22的前表面的开 口部22a与投入口11对置，通过投入口11和12关闭。在滚筒22的内圆周面，形成许多脱水孔22b。进而，在滚筒22的内圆周面，3个折流板23设置为在圆周方向上几乎相等的间隔。
在外槽20的上部设置由多个小孔形成的排气部20b。例如，当关闭门12时，外槽20内的空气的一部分被压至门12从排气部20b向外部排出。由此，门12的关闭顺利地进行。排气部20b相当于本发明的孔部。虽然存在排气部20b，但是在关闭门12的状态下，外槽20内几乎变为密闭的状态。
在外槽20的后方配有产生驱动滚筒22的扭矩的驱动电机30。驱动电机30是例如外转子型的DC无刷电机。驱动电机30在洗涤过程以及漂洗过程时，将滚筒22以加在滚筒22内的洗涤物的离心力比重力小的旋转速度旋转。另一方面，驱动电机30在脱水过程时，将滚筒22以加在滚筒22内的洗涤物的离心力比重力明显大的旋转速度旋转。
在外槽20的底部形成排水口部20c。在排水口部20c中设置排水阀40。排水阀40与排水管41连接。当打开排水阀40时，积存于外槽20内的水，流过排水管41排出到机外。
在外槽20的外侧配置有烘干单元50。烘干单元50具备：循环风路51、循环送风机52、加热器53。循环风路51的吸气口51a设置在外槽20的后表面下部，循环风路51的排气口51b设置在外槽20的前上部。循环送风机52将用于烘干洗涤物的烘干风在外槽20和循环风路51之间循环。加热器53加热烘干风。循环风路51包括以沿着外槽20的后表面的方式上下延伸的纵风路51c。纵风路51c作为除湿部发挥作用。即，在纵风路51c中，水从上方流过，夺取滚筒22内的洗涤物的水分并且从外槽20排出的烘干风与流过纵风路51c的水之间进行热交换。由此，除去烘干风的水分。循环送风机52相当于本发明的风产生部。
在外槽20的上方配有臭氧产生装置61。臭氧产生装置61是放电方式的臭氧产生装置，在一对电极间产生电晕放电、无声放电等的放电，从流过一对电极间的空气生成臭氧。臭氧产生装置61经由臭氧供给管62在循环风路51中与循环送风机52的吸气口侧连接。当循环送风机52旋转时，由于吸气口侧变成负压，所以由臭氧产生装置61产生的臭氧被吸入到循环送风机52。吸入的臭氧与烘干风混合并供给滚筒22内。臭氧产生装置61也可以是放电方式以外的方式，例如，也可以是紫外线方式的臭氧产生装置。臭氧产生装置61相当于本发 明的臭氧产生部。
在外槽20的上方，还配置有超声波加湿装置70。超声波加湿装置70产生雾。产生的雾，通过雾供给管71供给外槽20以及滚筒22内。超声波加湿装置70相当于本发明的雾产生部。
在机壳10内的后方上部配置有供水阀80。供水阀80与水龙头连接。供水阀80是三通阀，具有第一阀81、第二阀82以及第三阀83。第一阀81经由第一管84与外槽20的后部连接。在供水过程中，当打开第一阀81时，流过第一管84的自来水供给外槽20内。第二阀82经由第二管85与纵风路51c的上部连接。在烘干过程中，当打开第二阀82时，通过第二管85的自来水被供给纵风路51c。如上所述，供给纵风路51c的水用于烘干风的除湿。第三阀83经由第三管86与超声波加湿装置70连接。在需要向超声波加湿装置70补给水时，打开第三阀83。当打开第三阀83时，通过第三管86的自来水被供给超声波加湿装置70。
图2是表示超声波加湿装置70的结构的、蓄水箱701的剖面的侧面图。
超声波加湿装置70具有积存水的蓄水箱701。在蓄水箱701中，在后表面形成吸气口701a，在前表面形成放出口701b，在上表面形成供水口701c。此外，在蓄水箱701中，在底面设有超声波振荡器702，在前表面设有水位检测器703。在吸气口701a中，连接有吸气管704。在吸气管704中设有吸气风扇705。放出口701b与雾供给管71连接。供水口701c与第三管86连接。
水位检测器703检测上限的水位以及下限的水位。当通过水位检测器703检测出下限的水位时，打开第三阀83，通过第三管86向蓄水箱701内补给水。当水位检测器703检测出上限的水时，关闭第三阀83，停止水的补给。当在蓄水箱701内积存水的状态下，超声波振荡器702以及吸气风扇705工作。当超声波振荡器702工作时，通过超声波振动，从积存的水产生雾。当吸气风扇705工作时，由吸气管704吸入空气，吸入的空气被导入到蓄水箱701内。导入的空气获取雾，从放出口701b排出。获取雾的空气通过雾供给管71以及外槽20供给滚筒22内。
图3是表示滚筒式洗衣烘干机1的结构的框图。
滚筒式洗衣烘干机1，除上述构成之外，具有：控制部101、存储部102、操作部103、水位传感器104以及门锁装置105。
操作部103包括电源按钮103a、开始按钮103b、进程选择按钮103c以及空气洗涤按钮103d。电源按钮103a是用于接通和切断滚筒式洗衣烘干机1的电源的按钮。开始按钮103b是用于使运转开始的按钮。进程选择按钮103c用于从洗涤运转、洗涤烘干运转以及烘干运转所涉及的多个运转进程中选择任意的运转进程的按钮。空气洗涤按钮103d是用于选择与洗涤运转等的运转进程分开设置的空气洗涤进程的按钮。此外，对空气洗涤进程的运转，随后进行详细地说明。操作部103将与用户所操作的按钮对应的输入信号输出到控制部101。操作部103相当于本发明的旋转选择操作部。
水位传感器104检测外槽20内的水位，将与检测出的水位对应的水位检测信号输出到控制部101。
门锁装置105根据来自控制部101的控制信号进行门12的上锁以及解锁。
存储部102包括EEPROM、RAM等。在存储部102中，存储用于执行各种洗涤运转进程的洗涤运转的程序，以及，存储用于执行空气洗涤进程的运转的程序。此外，在存储部102中，存储用于这些程序的执行的各种参数和各种控制标志。
控制部101基于来自操作部103、水位传感器104等的各信号，根据存储于存储部102的程序控制驱动电机30、供水阀80、排水阀40、循环送风机52、加热器53、臭氧产生装置61、超声波加湿装置70、门锁装置105等的各负载。
滚筒式洗衣烘干机1根据基于进程选择按钮103c的用户的选择操作，进行各种运转进程的洗涤运转、洗涤烘干运转或烘干运转。洗涤运转是只进行洗涤的运转，按顺序执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。洗涤烘干运转是将从洗涤到烘干连续地进行的运转，在最终脱水过程后继续执行烘干过程。烘干运转是只进行烘干的运转，只执行烘干过程。
在洗涤过程以及漂洗过程中，在外槽20内直到达不到投入口11的下缘的规定的水位为止水被积存的状态下，滚筒22以作用于滚筒22内的洗涤物的离心力比重力小的旋转速度进行右旋转以及左旋转。通过折流板23将滚筒22内的洗涤物举起而落下，可以摔到滚筒22的内圆周面。由此，洗涤物进行洗涤，或者漂洗。
在中间脱水过程以及最终脱水过程中，滚筒22以作用于滚筒22内的洗涤物的离心力比重力明显变大的旋转速度单向地旋转。通过离心力的作用，洗涤 物被按压到滚筒22的内圆周面进行脱水。
在烘干过程中，由加热器53加热的烘干风在循环风路51和外槽20之间循环。此外，与洗涤过程以及漂洗过程相同，滚筒22右旋转以及左旋转。滚筒22内的洗涤物通过折流板23搅拌的同时，与导入滚筒22内的烘干风接触。通过接触从洗涤物夺取水分的烘干风，在纵风路51c内除湿后，再次用加热器53加热，导入滚筒22内。像这样烘干洗涤物。此外，在将不希望搅拌的洗涤物进行烘干的情况下，在烘干过程中，不旋转滚筒22。
进而，滚筒式洗衣烘干机1与上述洗涤运转等不同，另外基于由用户进行的空气洗涤按钮103d的操作，进行通过臭氧进行衣物、包、鞋等的处理对象物的除臭、除菌等的空气洗涤进程的运转。
空气洗涤进程的运转包括：臭氧产生过程，将臭氧产生装置61产生的臭氧供给滚筒22内进行处理对象物的除臭、除菌等；以及臭氧分解过程，在该臭氧产生过程之后进行的、通过分解使残留于滚筒22内的臭氧消失。通过臭氧分解过程，滚筒22内的臭氧浓度充分降低后，结束空气洗涤进程，能对门12进行解锁并取出处理对象物。
为了缩短从臭氧产生过程结束到能取出处理对象物的时间(以下，称为“取出等待时间”)，需要促进臭氧的分解。
可知周围的温度越高越促进臭氧的分解。因此，例如，可以采用下述结构，即将通过加热器加热的风供给滚筒22内并对滚筒22内进行加热，促进臭氧的分解。然而，在构成为通过加热促进臭氧的分解的情况下，易消耗比较大的电力。此外，所这样的结构，难适用于处理对象物不耐热的情况。
因此，本申请的发明人考虑了代替加热而用其它的条件促进臭氧的分解的方法的结果是，发现了对残留有臭氧的滚筒22内进行加湿，可促进臭氧的分解。
图4(a)是表示臭氧产生过程结束后，在自然放置的情况下的滚筒22内的臭氧浓度的随时间的变化的图。图4(b)以及(c)是表示臭氧产生过程结束后，在滚筒22内被加湿的情况下的滚筒22内的臭氧浓度的随时间的变化的图。图4(b)是表示将雾供给滚筒22内使滚筒22内的湿度上升到100％附近的情况的臭氧浓度的随时间的变化，图4(c)是表示将雾供给滚筒22内使滚筒22内的湿度上升到几乎80％的情况的臭氧浓度的随时间的变化。图4(a)～(c)是描画出在滚筒22内的臭氧浓度超过20ppm的状态下执行臭氧产生过程后，停止臭 氧的供给，到滚筒22内的臭氧浓度变为0.09ppm为止，滚筒22内的臭氧浓度、温度以及湿度的曲线图。
此外，在图4(a)～(c)的试验中，为了易确认基于加湿的臭氧的分解的促进效果，将臭氧产生过程中的臭氧浓度设定为比实际的空气洗涤进程的运转下的臭氧浓度高的值。
如图4(b)以及(c)所示，在对滚筒22内进行加湿了的情况下，明确得知，与图4(a)所示的自然放置的情况相比，从停止臭氧的供给到臭氧浓度降低为0.09％为止的时间变短，在对滚筒22内进行了加湿的情况下促进臭氧的分解。
虽然就基于加湿减少臭氧浓度的理由，并不明确，但有可能考虑到以下原因：臭氧气体溶解在加湿中的微小的水(雾)中，或者反应并分解。与臭氧的水中的反应机理相同，考虑推进以下反应。

在本实施方式的滚筒式洗衣烘干机1中，根据通过加湿促进臭氧的分解的新见解，在空气洗涤进程中的臭氧分解过程由将雾供给滚筒22内并对滚筒22内进行加湿的加湿过程和除去滚筒22内的雾并使滚筒22内的湿度降低的除湿过程构成。
以下对在空气洗涤进程的运转中具体的控制内容进行说明。
图5是表示空气洗涤进程中的控制处理的流程图。当通过空气洗涤按钮103d的操作，选择空气洗涤进程，然后，当操作开始按钮103b时，控制部101开始空气洗涤进程的运转。此外，通过空气洗涤按钮103d的按下次数，由用户设定空气洗涤进程中是否旋转滚筒22。在用户将包、鞋、易变形的衣物等不希望通过滚筒22的旋转进行搅拌的处理对象物收纳在滚筒22内的情况下，进行使滚筒22不旋转的设定。
当开始运转时，控制部101首先执行排水存水弯供水过程(S11)。在排水存水弯供水过程中，控制部101在打开排水阀40的状态下打开第一阀81，供水 到外槽20内。在排水阀40的下游设有用于预先积存水的排水存水弯，供给外槽20的水通过排水阀40积存于排水存水弯。在排水阀40和排水存水弯之间，连接有从设在外槽20的溢水口延伸的溢水管。由于在排水存水弯中未进行水封，所以在臭氧产生过程中，防止供给滚筒22内的臭氧通过溢水管以及排水管41漏出到机外。
预定的供水时间，例如，当经过1分20秒时，控制部101关闭第一阀81，结束排水存水弯供水过程。
接下来，控制部101判断是否进行使滚筒22旋转的设定(S12)。控制部101如果进行了使滚筒22旋转的设定(S12：是)，则在开始滚筒22的旋转后(S13)，进入臭氧产生过程的处理(S14)，如果未进行使滚筒22旋转的设定(S12：NO)，则不使滚筒22旋转，进入臭氧产生过程的处理(S14)。
在臭氧产生过程中，控制部101在使循环送风机52工作后，使臭氧产生装置61工作。由臭氧产生装置61产生的臭氧与烘干风混合并供给滚筒22内。滚筒22内的处理对象物与臭氧接触，处理对象物被除臭以及除菌。当预定的臭氧产生时间，例如，经过10分钟时，控制部101停止臭氧产生装置61以及循环送风机52，结束臭氧产生过程。
接下来，控制部101执行臭氧分解过程。控制部101首先执行加湿过程(S15)，接着执行除湿过程(S16)。此外，在步骤S13中，在使滚筒22旋转的情况下，即使在臭氧分解过程中也维持滚筒22的旋转。
图6是表示在加湿过程中的控制处理的流程图。
在加湿过程中，控制部101使超声波加湿装置70工作(S101)。由超声波加湿装置70产生的雾通过雾供给管71供给外槽20内以及滚筒22内，对滚筒22内进行加湿。通过加湿，滚筒22内的湿度例如从设为目标的80％上升到100％左右的值。预定的加湿时间，例如，当经过8分钟时(S102：是)，控制部101停止超声波加湿装置70，结束加湿过程并进入除湿过程的处理。
返回图5，在除湿过程中，控制部101使循环送风机52工作。在外槽20以及滚筒22内产生风，通过排气部20b雾被一点点地排出到外槽20的外面。由此，滚筒22内的湿度缓缓地降低。当经过预定的除湿时间例如2分钟时，控制部101停止循环送风机52，结束除湿过程。
在臭氧分解过程中，分解滚筒22内的臭氧。此时，由于在加湿过程中，对 滚筒22内进行加湿，所以促进臭氧的分解。在设定为旋转滚筒22的情况下，由于臭氧分解过程期间滚筒22进行旋转，所以滚筒22内被全部加湿，均匀地促进滚筒22内的臭氧的分解。这样，当臭氧分解过程结束时，滚筒22内的臭氧浓度降低到能取出处理对象物的浓度。
当结束臭氧分解过程时，控制部101判断滚筒22是否在旋转(S17)，如果未旋转(S17：NO)，则维持原样地结束空气洗涤进程的运转。控制部101对门12进行解锁，处理对象物的取出成为可能。在滚筒22旋转的情况下(S17：是)，控制部101停止滚筒22后(S18)，结束空气洗涤进程的运转。
此外，在空气洗涤进程的运转中滚筒22旋转的情况下，滚筒22也可以连续地旋转，也可以间歇地旋转。在滚筒22间歇地旋转的情况下，工作时间也可以比停止时间长，停止时间也可以比工作时间长。此外，滚筒22也可以单向地间歇地旋转，也可以右旋和左旋混合地旋转。
如上所述，根据本实施方式，在臭氧分解过程中将雾供给滚筒22内，对滚筒22内进行加湿。由此，促进残留于滚筒22内的臭氧的分解。因此，能缩短处理对象物的取出等待时间。并且，由于通过超声波加湿装置70加湿所需要的耗电与通过加热器加热所需要的耗电相比能变小，所以能抑制耗电的同时，能实现残留的臭氧的分解的促进。此外，在处理对象物不耐热的情况下，也能实现残留的臭氧的分解的促进。
进而，根据上述实施方式，在通过雾排出到外槽20的外面来降低滚筒22内的湿度后，结束空气洗涤进程的运转。由此，能防止用户将手放入湿度高的滚筒22内而觉得不舒服的情况。
进而，根据上述实施方式，在臭氧分解过程中使滚筒22旋转，对滚筒22内全部加湿。由此，能均匀地促进滚筒22内的臭氧的分解。
进而，根据上述实施方式，在进行不希望通过滚筒22的旋转被搅拌的处理对象物的除臭、除菌等的情况下，通过操作部103的空气洗涤按钮103d的操作，能设定为不旋转滚筒22。由此，能防止通过滚筒22的旋转产生对处理对象物的损伤等的不好之处。
以上，虽然对本发明的实施方式进行了说明，但本发明没有对上述实施方式等做任何限制，此外，本发明的实施方式也在上述以外有各种变更的可能。
＜变更例1＞
在上述实施方式中，使用超声波加湿装置70向滚筒22内供给雾。与此相对，在本变更例中，使用雾喷嘴90向滚筒22内供给雾。
图7是表示本变更例所涉及的滚筒式洗衣烘干机1的结构的侧面剖视图。在本变更例中，在外槽20的后上部配有雾喷嘴90，雾喷嘴90经由第三管86与第三阀83连接。当打开第三阀83时，将自来水供给雾喷嘴90。雾喷嘴90将供给的水变换成雾，将变换的雾向外槽20以及滚筒22内进行喷雾。雾喷嘴90相当于本发明的雾产生部。
图8是表示本变更例所涉及的加湿过程中的控制处理的流程图。在本变更例中，空气洗涤进程的运转中的加湿过程的控制处理与上述实施方式不同。以下，对加湿过程的控制处理，参照图8进行说明。
当进入加湿过程时(S15)，控制部101打开第三阀83(S201)。从雾喷嘴90向外槽20以及滚筒22内进行喷雾。由此，对滚筒22内进行加湿。
当预定的喷雾时间，例如，经过2分钟时(S202：是)，控制部101关闭第三阀83(S203)。由此，停止雾的喷雾。由于基于雾喷嘴90的每单位时间的雾的供给量，比基于上述实施方式的超声波加湿装置70的每单位时间的雾的供给量多，所以在短时间内滚筒22内的湿度从设为目标的80％上升到100％左右的值。因此，控制部101在很早的阶段就停止雾的喷雾，之后，加湿时间，例如，从加湿过程的开始直到经过10分为止，保持原样地等待。当经过加湿时间时(S204：是)，控制部101结束加湿过程并加入进入除湿过程的处理。
根据本变更例的结构，能实现与上述实施方式相同的作用效果。
特别是，在本变更例中，使用用于产生雾的雾喷嘴90，消耗的电力变为用于开闭向雾喷嘴90供给水的第三阀83的电力。因此，与使超声波加湿装置70工作的情况相比，能抑制耗电。
＜变更例2＞
在变更例1中，使用雾喷嘴90向滚筒22内供给雾。与此相对，在本变更例中，可以采用通过将积存于外槽20的水由滚筒22的旋转使其飞散而产生雾的结构。在本变更例中，滚筒22相当于本发明的雾产生部。
图9是表示本变更例所涉及的滚筒式洗衣烘干机1的结构的侧面剖视图。在本变更例中，如上所述，由于不使用超声波加湿装置70和雾喷嘴90，所以供水阀80成为具有第一阀81和第二阀82的二通阀。
图10是表示本变更例所涉及的空气洗涤进程中的控制处理的流程图。在图10所示的本变更例的控制处理中，不执行在图5所示的上述实施方式的控制处理中执行的步骤S12的处理和步骤S17的处理。即，当排水存水弯供水过程结束时(S11)，控制部101使滚筒22旋转(S13)，进入臭氧产生过程的处理(S14)。进而，当结束构成臭氧分解过程的除湿过程时(S16)，控制部101使滚筒22停止(S18)。
图11是表示本变更例所涉及的加湿过程中的控制处理的流程图。
当进入加湿过程时(S15)，控制部101将正在旋转的滚筒22暂时停止(S301)。接下来，控制部101打开第一阀81(S302)。由此，自来水被供给外槽20内。控制部101判断外槽20内的水位是否到达可飞散的水位(S303)。如图9所示，可飞散水位被设定为水面只与滚筒22的外圆周面接触的水位。当外槽20内的水位达到可飞散水位时(S303：是)，控制部101关闭第一阀81(S304)。由此，停止向外槽20的供水。
控制部101再次使滚筒22旋转(S305)。滚筒22的外圆周面的脱水孔22b的外缘在加工上仅向外突出等的、具有仅有的凹凸。因此，当通过旋转滚筒22由滚筒22的外圆周面扫过水面时，水飞散产生雾。通过产生的雾，对滚筒22内进行加湿。与上述实施方式相同，通过加湿，滚筒22内的湿度例如，从设为目标的80％上升到100％左右的值。预定的加湿时间，例如，当经过8分钟时(S306：是)，控制部101打开排水阀40(S307)，结束加湿过程。虽然继续滚筒22的旋转，但由于外槽20内的水位降低，滚筒22的外圆周面不与水面接触，所以停止雾的产生。
根据本变更例的结构，通过滚筒22的旋转，除能防止对不希望搅拌的处理对象物产生不好之处的的作用效果外，还能实现与上述实施方式相同的作用效果。
特别是，在本变更例中，由于采用通过滚筒22的旋转使雾产生的结构，所以不需要超声波加湿装置70等的产生雾的专用的装置，能抑制成本的增加。
＜其它变更例＞
在上述实施方式、上述变更例1以及上述变更例2的结构中，在进行耐热的处理对象物的除臭、除菌等的情况下，在加湿过程中，除加湿外，也可附加对滚筒22内进行加热的结构。此外，在这种情况下，在操作部103设有切换按 钮，通过该切换按钮，设定是否对滚筒22内进行加热。用户在进行耐热的处理对象物的除臭、除菌等的情况下，对滚筒22内进行加热的设定。
图12是在上述实施方式的结构中附加对滚筒22内进行加热的结构的情况的加湿过程中的控制处理的流程图。在图12所示的控制处理中，对图5所示的控制处理，附加步骤S111～步骤S114的处理。
本变更例中，控制部101在使超声波加湿装置70工作后，判断是否对滚筒22内进行加热的设定(S111)。在设定为对滚筒22内进行加热的情况下(S111：是)，控制部101使加热器53以及循环送风机52工作(S112)。通过加热器53加热的风供给滚筒22内，对滚筒22内进行加热。由此，不仅通过加湿还通过加热促进残留于滚筒22内的臭氧的分解。因此，很大地促进臭氧的分解。
当经过预定的加湿/加热时间时(S113：是)，控制部101停止加热器53以及循环送风机52(S114)。进而，控制部101停止超声波加湿装置70(S103)，结束加湿过程。通过由加湿和加热来很大地促进臭氧的分解，与只有加湿的情况相比，滚筒22内的臭氧浓度很早地降低。因此，加湿/加热时间成为比加湿时间短的时间。
图13是在上述变更例1的结构中附加对滚筒22内进行加热的结构的情况的加湿过程中的控制处理的流程图。在图13所示的控制处理中，对图8所示的控制处理，附加步骤S211～步骤S216的处理。
本变更例中，控制部101在打开第三阀83后，判断是否设定对滚筒22内进行加热(S211)。在设定为对滚筒22内进行加热的情况下(S211：是)，控制部101使加热器53以及循环送风机52工作(S212)。通过对滚筒22内进行加热，很大地促进残留于滚筒22内的臭氧的分解。
当经过喷雾时间时(S213：是)，控制部101关闭第三阀83(S214)。进而，当经过加湿/加热时间时(S215：是)，控制部101停止加热器53以及循环送风机52(S216)，结束加湿过程。
图14是在上述变更例2的结构中附加对滚筒22内进行加热的结构的情况的加湿过程中的控制处理的流程图。在图14所示的控制处理中，对图11所示的控制处理，附加步骤S311～步骤S314的处理。
在本变更例中，控制部101在使滚筒22再次旋转后，判断是否设定对滚筒22内进行加热(S311)。在设定对滚筒22内进行加热的情况下(S311：是)， 控制部101使加热器53以及循环送风机52工作(S312)。通过对滚筒22内进行加热，很大地促进残留于滚筒22内的臭氧的分解。当经过加湿/加热时间时(S313：是)，控制部101停止加热器53以及循环送风机52(S314)。进而，控制部101打开排水阀40(S307)，结束加湿过程。
如果做成这些变更例的结构，与只进行滚筒22内的加湿的结构相比，由于很大地促进臭氧的分解，所以能缩短处理对象物的取出等待时间。此外，由于与进行滚筒22内的加热的结构相比，也能缩短取出等待时间，所以与只能进行加热的结构相比，能抑制作为臭氧分解过程整体的耗电。
进而，如果做成这些变更例的结构，在进行不耐热的处理对象物的除臭、除菌等的情况下，通过操作部103的操作，由于能设定对滚筒22内不进行加热，所以能防止通过加热使不耐热的处理对象物损伤。
此外，在图12～图14所示的变更例中，加热器53相当于本发明的加热部，操作部103相当于本发明的加热选择操作部。
在上述实施方式中，在与洗涤运转、洗涤烘干运转以及烘干运转分开设置的空气洗涤进程的运转中执行臭氧产生过程和臭氧分解过程。然而，在洗涤烘干运转、烘干运转中的烘干过程后，也可执行臭氧产生过程和臭氧分解过程。
进而，在上述实施方式中，滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转。然而，滚筒式洗衣烘干机1也可构成为，滚筒22以水平轴为中心进行旋转。
进而，在上述实施方式中，虽然例示了具有通过臭氧进行衣物的除臭、除菌等功能的滚筒式洗衣烘干机，但本发明并不局限于滚筒式洗衣烘干机，也能适用于具有通过臭氧进行衣物的除臭、除菌等功能的滚筒式洗衣机、全自动洗衣机、全自动洗衣烘干机、衣物烘干机等。进而，本发明除清洗功能外，还能适用于具有通过臭氧进行鞋的除臭、除菌等的功能的鞋清洗机；通过臭氧进行西服的除臭、除菌等的西服干洗机等；以及通过臭氧进行处理对象物的除臭、除菌等的各种臭氧处理装置。
此外，本发明的实施方式在权利要求书所示的技术思想的范围内可以适当地进行各种变更。
