Description

洗衣干衣机 技术领域
本发明涉及洗衣干衣机。
背景技术
以往，已知一种洗衣干衣机，其在通过配置于洗涤脱水桶的底部的波轮，在洗涤脱水桶内产生水流来对衣物进行洗涤的所谓涡卷式洗衣机(全自动洗衣机)中搭载有衣物的干衣功能。这种洗衣干衣机的一个例子例如记载于专利文献1。
在专利文献1的洗衣干衣机中，在具有洗涤物投入口的上面板配置有用于向洗涤脱水桶内供给高温空气的热风供给单元。配置有洗涤桶脱水桶的外桶的上表面的开口由具有内盖的外桶罩覆盖。由热风供给单元生成的热风经过连接于外桶罩的热风管道，从外桶的上方被吹出至洗涤脱水桶内。在内盖形成有排气孔，供给至洗涤桶内的热风从排气孔出至外桶的外侧，从外箱的背面的通气孔等被排出机外。
上述的结构由于在外桶上表面的内盖形成有排气孔，因此，从外桶的上方供给来的热风还未行至洗涤脱水桶的下部就容易排出排气孔。因此，在洗涤脱水桶内，只有洗涤物的上表面容易接触热风，热风难以渗透洗涤物。因此，在上述的结构存在干衣效率低下的顾虑。

用于解决问题的方案
本发明的第一方案的洗衣干衣机具备：外桶，弹性地支承于机壳内；洗涤脱水桶，可旋转地配置于所述外桶内；热风供给部，包括加热器和风扇，通过所述风扇的工作将通过所述加热器的工作而被加热的空气从所述外桶的上部供给至所述洗涤脱水桶内；以及排出口，设于所述外桶的下部，供与所述洗涤脱水桶内的洗涤物接触后的空气排出。
根据上述的结构，由于来自外桶内的空气的排出口形成于外桶的下部，因此，从上方送入外桶内的热风容易行至洗涤脱水桶的下部。由此，热风容易渗透洗涤脱水桶内的洗涤物，因此能期待干衣效率的提高。
本方案的洗衣干衣机可以采用还具备排气部的结构，所述排气部在洗衣时不会泄露蓄积于所述外桶内的水，在干衣时将从所述排出口流出来的空气排出。例如，所述排气部可以包括连接于所述排出口并向上方延伸的排气管道。在该情况下，在所述排气管道形成有排气口，所述排气口位于比水从所述外桶内溢出的溢水水位高的位置。
根据上述的结构，不用担心洗衣时水会泄漏，能将空气的排出口设于外桶的下部。
本方案的洗衣干衣机可以采用如下结构：所述机壳包括具有洗涤物的投入口的上面板，所述热风供给部配置于设于所述上面板的收容室，所述热风供给部的吸气口与所述收容室的内壁面以间隔状态对置，通过所述风扇的工作，流通于所述收容室的空气被摄入所述吸气口。
根据上述的结构，由于能通过加热器，将通过发自热风供给部的热量而被加热的空气加热，因此能抑制加热器的加热量，能抑制干衣过程中洗衣干衣机的耗电量。
在采用上述结构的情况下，可以进一步采用如下结构：所述收容部具有连通至所述机壳与所述外桶之间的空间的开口，通过所述风扇的工作，所述空间内的空气被摄入并流通于所述收容室。
当采用这样的结构时，由于能将通过发自外桶的热量而被加热的空气摄入收容室内，因此能将被进一步加热的空气摄入热风供给部的吸气口，能进一步抑制加热器的加热量。
在本方案的洗衣干衣机可以采用如下结构：所述机壳包括具有洗涤物的投入口的上面板，所述热风供给部配置于设于所述上面板的收容室，所述收容室具有连通至所述机壳与所述外桶之间的空间的开口，所述热风供给部的吸气口与所述开口对置，通过所述风扇的工作，所述空间内的空气被摄入所述吸气口。
根据上述的结构，由于能将通过发自外桶的热而被加热的空气摄入热风供给部，因此能抑制干衣过程中洗衣干衣机的耗电量。
如上所述，在洗衣干衣机采用将摄入热风供给部的空气通过来自外桶、热风供给部的热量来加热的结构的情况下，进一步地，洗衣干衣机可以采用如下结构：还具备控制部，该控制部进行第一干衣运转和第二干衣运转，所述第一干衣运转使所述加热器和所述风扇工作，将被所述加热器加热的空气从所述热风供给部供给至所述外桶内；所述第二干衣运转紧接着该第一干衣运转，在使所述加热器停止的状态下使所述风扇工作，将未被所述加热器加热的空气从所述热风供给部供给至所述外桶内。
当采用这样的结构时，由于能利用热风供给部、外桶的余热来烘干洗涤物，因此能抑制干衣过程中洗衣干衣机的耗电量。

在上面板12的后部，以从外部被关闭的方式设有收容室100。收容室100由收容凹部101和后罩102构成，其中，收容凹部101具有底面101a、前侧面101b、后侧面101c、左侧面101d以及右侧面101e且上表面打开，后罩102覆盖收容凹部101的上表面。收容室100内配置有热风供给单元50、给水单元60、水位传感器70等。
如图2所示，热风供给单元50在收容室100内配置于中央偏左侧。热风供给单元50具备：外壳51、风扇52、加热器53以及热风管道54。热风供给单元50相当于本发明的热风供给部。
外壳51具有向右方延伸后朝前方折曲的呈大致L字的长方体形状。在外壳51，在左端侧的后表面形成有吸气口51a，在右端侧的底面形成有排气口51b。吸气口51a与收容凹部101的后侧面101c以间隔状态对置，在该后侧面101c的与吸气口51a对置的区域，未形成如外部空气的摄入口这种与外部连通的开口。而且，在外壳51的合适位置设有用于固定热风供给单元50的多个第一安装部51c。
风扇52是离心扇，包括鼓风机52a和使鼓风机52a旋转的电机52b。鼓风机52a以与吸气口51a对置的方式配置于外壳51内。加热器53在外壳51内配置于鼓风机52a的下游。加热器53是可自调温度的PCT加热器(半导体加热器)，要加热的空气的温度越低，其发热量就变得越大。需要说明的是，热风供给单元50也可以使用离心扇以外的风扇、PCT加热器以外的加热器。
热风管道54由弹性构件等来形成，从而具有挠性，一端连接于外壳51的排气口51b，另一端连接于形成于外桶罩22的吹出口20b。吹出口20b面向洗涤脱水桶24内。
给水单元60在收容室100内配置于中央偏右侧。给水单元60包括：注水口部61、给水阀62、洗澡水泵63以及给水管道64。注水口部61具有前后较长的长方体形状。在注水口部61，在上表面形成有用于摄入自来水的第一流入口61a和第二流入口61b、以及用于摄入洗澡水的第三流入口61c，在底面形成有注水口61d。此外，供柔顺剂投入的柔顺剂盒(未图示)以能从前方抽出的方式 收容于注水口部61。而且，在注水口部61的合适位置设有用于固定给水单元60的多个第二安装部61e。
给水阀62是双联阀，其第一流出口62a连接于第一流入口61a，其第二流出口62b连接于第二流入口61b。在给水阀62的上表面形成有第一连接口62c。第一连接口62c在收容凹部101由后罩102覆盖的状态下面向外部，从水龙头延伸的给水软管(未图示)连接于第一连接口62c。
洗澡水泵63的洗澡水给水软管63a连接于第三流入口61c。在洗澡水泵63的上表面形成有第二连接口63b。第二连接口63b在收容凹部101由后罩102覆盖的状态下面向外部，洗澡水软管(未图示)连接于第二连接口63b。洗澡水软管在从浴缸内供给洗澡水时，其顶端的吸水口部浸入浴缸中。
给水管道64由弹性构件等来形成，从而具有挠性，一端连接于注水口部61的注水口61d，另一端连接于形成于外桶罩22的给水口(未图示)。
当给水阀62的第一流出口62a侧的阀被打开时，自来水经过第一流入口61a被摄入注水口部61。被摄入的自来水不经由柔顺剂盒就从注水口61d被排出。同样，通过洗澡水泵63的工作从而经过第三流入口61c被摄入注水口部61的洗澡水也不经由柔顺剂盒就从注水口61d被排出。另一方面，当给水阀62的第二流出口62b侧的阀被打开时，自来水经过第二流入口61b被摄入注水口部61。被摄入的自来水经过柔顺剂盒，以混合有柔顺剂的状态从注水口61d被排出。从注水口61d排出的自来水、洗澡水经由给水管道64供给至外桶20内。
水位传感器70在收容室100内配置于给水阀62的右方。在外桶20的底部形成有未图示的防气阀(air trap)，水位传感器70和防气阀由空气软管71连接。水位传感器70检测洗涤脱水桶24内即外桶20内的水位。
如图3所示，在收容凹部101的底面101a，在配置有热风供给单元50的位置形成有与第一安装部51c对应的多个第一安装凸起103，在配置有给水单元60的位置形成有与第二安装部61e对应的多个第二安装凸起104。此外，在底面101a，在配置有水位传感器70的位置形成有传感器安装部105。而且，在底面101a形成有：第一开口部106，供热风管道54和给水管道64穿过；第二开口部107，供出自热风供给单元50的电气布线穿过；第三开口部108，供出自 给水单元60和水位传感器70的电气布线穿过；以及第四开口部109，供延伸自水位传感器70的空气软管71穿过。第一开口部106、第二开口部107、第三开口部108以及第四开口部109相当于本发明的开口。
第一安装部51c通过螺丝等固定于第一安装凸起103，由此，热风供给单元50以不与收容凹部101的底面101a接触的状态固定于收容室100内。此外，第二安装部61e通过螺丝等固定于第二安装凸起104，由此，给水单元60以不与收容凹部101的底面101a接触的状态固定于收容室100内。而且，水位传感器70以不与收容凹部101的底面101a接触的状态固定于传感器安装部105。如此，由于热风供给单元50、给水单元60以及水位传感器70均不与底面101a接触，因此第一开口部106、第二开口部107、第三开口部108以及第四开口部109难以被热风供给单元50、给水单元60以及水位传感器70堵塞。
在收容室100，在前后、左右以及上下任一壁面，都未主动形成用于向收容室100内摄入空气的吸气口。但是，在形成于收容凹部101的底面101a的第一开口部106、第二开口部107、第三开口部108以及第四开口部109，在这些开口部106～109与穿过这些开口部106～109的热风管道54、给水管道64、各种电气布线、空气软管71等之间产生间隙。由此，在干衣过程中，这些开口部106～109作为向收容室100内摄入空气的吸气口发挥功能。
如图1所示，在外桶20的后侧的侧面，在下部形成有排出口20c。排出口20c连接有排气管道80。排气管道80向上方延伸，在其上端部附近形成有排气口83。排气管道80相当于本发明的排气部。
在机壳10的机身部11的后表面的与排气口83对置的位置，形成有由许多孔构成的机外排气口11a。理想的是，即使外桶20的上下位置根据投入洗涤脱水桶24内的洗涤物的重量而发生变化，且排气管道80的排气口83的上下位置也随之会发生变化，排气口83的至少局部也不会偏离机外排气口11a，最好是整个排气口83都不会偏离机外排气口11a。
图4是从后方观察安装有排气管道80的外桶20的图。图5是将外桶20和排气管道80在排气管道80的左右方向的中央部剖开后的主要部分的纵剖图。图6(a)是图5的沿A-A’线剖开后的排气管道80的剖视图，图6(b)是图5的沿B-B’线剖开后的排气管道80的剖视图。需要说明的是，为了方便，图 6(a)中将排气口83用点划线描绘出来。
参照图4至图6，对排气管道80的详细结构加以说明。
排气管道80通过将与机壳10对置的第一机壳81和与外桶20对置的第二机壳82前后重叠，并将彼此的凸缘部81a、82a通过振动熔接等接合方法以能隔水的方式接合而形成。排气管道80具有上下方向上长、前后方向上扁平的大致长方体形状。在排气管道80的上端部的位于机壳10侧的面，形成有大致长方形的长方形状的排气口83。在排气管道80的下端部的位于外桶20侧的面，形成有吸气口84。吸气口84具有圆筒状，向排气管道80的内部突出。排气管道80的下端部的左右宽度朝着吸气口84逐渐变窄。
形成于外桶20的侧面下部的排出口20c具有圆筒形状，并向外侧突出。排出口20c的外径与排气管道80的吸气口84的内径相等。排气管道80设计成吸气口84嵌入外桶20的排出口20c且外桶20侧的面几乎与外桶20紧贴，固定于外桶20。这时，排出口20c和吸气口84用密封件等以隔水状态连接。
在外桶20的上部形成有溢水室90。对于溢水室90而言，前面壁91的上侧朝外桶20内开口，当外桶20内的水位超过前面壁91的高度时，从外桶20内溢出的水流入溢水室90内。在溢水室90的底部形成有溢水口92，延伸自溢水口92的溢水管93的顶端部93a连接于延伸到排水软管41的溢水软管(未图示)。满溢至溢水室90的水从溢水口92排出，经过溢水管93和溢水软管被引导至排水软管41。排气管道80的排气口83形成于比前面壁91的高度位置即溢水水位Lofw高的位置。由于溢水水位Lofw是比由洗涤物的量决定的水位之中最高的最高水位Lmax高的位置，因此排气口83的位置为比最高水位Lmax高的位置。
排气管道80内蓄积了与洗衣时蓄积于外桶20内的水的水位同一水位的水。在本实施方式中，由于排气管道80的排气口83形成于比溢水水位Lofw高的位置，因此能防止洗衣时水从排气口83泄露。
在排气管道80的内部设有从左右的内壁面突出的上侧两个第一防壁部85和下侧两个第二防壁部86。第一防壁部85的突出长度小于第二防壁部86的突出长度。此外，右侧的第一防壁部85和第二防壁部86、以及左侧的第一防壁部85和第二防壁部86形成于排气管道80的不同的高度位置。
当洗衣时波轮26旋转时，由于外桶20内、排气管道80内水面起伏，因此水有可能在排气管道80内上升到更高的位置。但是，在本实施方式中，通过第一防壁部85以及第二防壁部86，能抑制由起伏引起的水位上升，因此，在洗衣时，水越发难以从排气口83泄露。
需要说明的是，理想的是至少排气管道80内的位于最高位置的第一防壁部85位于比溢水水位Lofw高的位置。此外，第一防壁部85的突出长度可以与第二防壁部86的突出长度相同。而且，右侧的第一防壁部85和第二防壁部86、以及左侧的第一防壁部85和第二防壁部86可以形成于排气管道80的同一高度位置。
图7是表示全自动洗衣干衣机1的结构的框图。
全自动洗衣干衣机1除了上述的结构以外，还具备控制单元200。控制单元200包括：控制部201、存储部202、电机驱动部203、离合器驱动部204、给水驱动部205、泵驱动部206、排水驱动部207、风扇驱动部208以及加热器驱动部209。
操作部16将从电源按钮16a、开始按钮16b、模式选择按钮16c等各种按钮中用户所操作的按钮的相应的输入信号输出给控制部201。水位传感器70检测外桶20内的水位，将与检测出的水位相应的水位检测信号输出给控制部201。
电机驱动部203根据来自控制部201的控制信号来驱动驱动电机31。离合器驱动部204根据从控制部201输出的控制信号来驱动离合器机构32a。
给水驱动部205根据来自控制部201的控制信号来驱动给水阀62。泵驱动部206根据来自控制部201的控制信号来驱动洗澡水泵63。排水驱动部207根据来自控制部201的控制信号来驱动排水阀40。
风扇驱动部208根据从控制部201输出的控制信号来驱动风扇52。加热器驱动部209根据从控制部201输出的控制信号来驱动加热器53。
存储部202包括EEPROM、RAM等。存储部202存储有用于执行各种运转模式的洗衣运转、洗衣干衣运转以及干衣运转的程序。此外，存储部202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201基于来自操作部16、水位传感器70等的各信号，根据存储于存 储部202的程序来控制电机驱动部203、离合器驱动部204、给水驱动部205、泵驱动部206、排水驱动部207、风扇驱动部208、加热器驱动部209等。
全自动洗衣干衣机1进行各种运转模式的洗衣运转、洗衣干衣运转或干衣运转。洗衣运转是仅进行洗衣的运转，依次执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。洗衣干衣运转是连续地进行从洗衣到干衣的运转，在最终脱水过程之后接着执行干衣过程。干衣运转是仅进行干衣的运转，仅执行干衣过程。
在洗涤过程以及漂洗过程中，在洗涤脱水桶24内蓄积有水的状态下，波轮26往右方向和左方向旋转。通过波轮26的旋转，洗涤脱水桶24内产生水流。在洗涤过程中，通过产生的水流和水中所含的洗涤剂对洗涤物进行洗涤。在漂洗过程中，通过产生的水流对洗涤物进行漂洗。
在中间脱水过程以及最终脱水过程中，洗涤脱水桶24和波轮26一体地高速旋转。通过洗涤脱水桶24产生的离心力的作用，洗涤物被脱水。
在干衣过程中，通过风扇52和加热器53的工作，从热风供给单元50向外桶20内供给热风。在洗涤脱水桶24内，波轮26反复进行右转和左转。洗涤脱水桶24内的洗涤物一边被波轮26搅拌，一边与导入洗涤脱水桶24内的热风接触而被烘干。
图8是表示干衣过程中的运转控制动作的流程图。
本实施方式中，在干衣过程中，进行加热烘干运转和紧接着该加热烘干运转的余热烘干运转。以下，参照图8，对干衣过程进行详细说明。
当开始干衣过程时，控制部201首先执行加热烘干运转。即，控制部201控制风扇驱动部208，使风扇52以第一转速工作(S1)，同时控制加热器驱动部209，使加热器53工作(S2)。第一转速例如设为3500rpm。而且，控制部201控制电机驱动部203，使驱动电机31工作，使波轮26左右发转动作(S3)。例如，反转工作的通断时间设为3秒接通-1.5秒切断。干衣过程中的接通时间比通常的洗涤过程或漂洗过程的接通时间长，通过这种接通时间长的波轮26的反转工作，洗涤物在洗涤脱水桶24内被灵活移动。
当风扇52旋转时，空气经过收容室100的底面101a的第一开口部106、第 二开口部107、第三开口部108以及第四开口部109，从机壳10与外桶20之间的空间被摄入收容室100内。被摄入的空气在收容室100内流动，奔向设于热风供给单元50的外壳51的吸气口51a，从吸气口51a被吸入外壳51内。被吸入的空气由加热器53加热变成热风，经过热风管道54，从上方吹向外桶20内。在外桶20内，通过使波轮26反复进行左右的反转工作，从而洗涤脱水桶24内的洗涤物被搅拌。吹向外桶20内的热风从上方吹入洗涤脱水桶24内，与在洗涤脱水桶24内被搅拌着的洗涤物接触，将水分从洗涤物中去除。由此，洗涤物被烘干。从洗涤物中去除了水分的空气穿过洗涤脱水桶24的脱水孔24a等，在洗涤脱水桶24与外桶20之间流动，从设于外桶20的侧面下部的排出口20c排出。被排出的空气在排气管道80内流动，经过排气管道80的排气口83和机壳10的机外排气口11a被排出机外。需要说明的是，在图1中用箭头示出了加热烘干运转中的空气的流向。
当加热烘干运转持续进行时，通过热风的热量，热风供给单元50的外壳51自身以及外桶20自身被加热。如此一来，通过发自外桶20的热量而被加热的空气被摄入收容室100内，在收容室100内流动的空气通过发自外壳51的热量被进一步加热。这样，比全自动洗衣干衣机1的外部空气温度高的空气被摄入热风供给单元50的吸气口51a。由此，与外部空气直接被摄入热风供给单元50的情况相比，抑制了加热器53的加热量，抑制了耗电量。
控制部201判定是否经过了预先设定的加热烘干时间(S4)。并且，当经过了加热烘干时间时(S4：是)，控制部201使加热器53停止(S5)。由此，结束加热烘干运转。
接着，控制部201执行余热烘干运转。控制部201使风扇52的转速上升，使风扇52以高于第一转速的第二转速工作(S6)。第二转速例如设为5000rpm。
通过外桶20和外壳51的余热而被加热的空气被摄入热风供给单元50的吸气口51a，该空气无需通过加热器53来加热就作为余热风向被供给至外桶20内。洗涤脱水桶24内的洗涤物与余热风接触而被烘干。在此，由于风扇52的转速提高，因此余热风的风量比加热烘干运转时的热风的风量大。由此，能通过增加风量来补偿与洗涤物接触的风的温度变低所导致的干衣效率的降低。
控制部201判定是否经过了预先设定的余热烘干时间(S7)。并且，当经过 了余热烘干时间时(S7：是)，控制部201使风扇52停止(S8)，并使驱动电机31停止，使波轮26停止(S9)。由此，结束余热烘干运转，结束干衣过程。
<本实施方式的效果>
以上，根据本实施方式，由于来自外桶20内的空气的排出口20c形成于外桶20的下部，因此，从上方送入外桶20内的热风容易行至洗涤脱水桶24的下部。由此，热风变得容易渗透洗涤脱水桶24内的洗涤物，因此能期待干衣效率的提高。
此外，根据本实施方式，设有连接于排出口20c并向上方延伸的排气管道80，在排气管道80，在高于水从外桶20内溢出的溢水水位Lofw的位置形成有排气口83，因此，在洗衣时，蓄积于外桶20内的水不会泄漏，在干衣时，能将从排出口20c流出来的空气排出。由此，不用担心洗衣时水会泄漏，能在外桶20的下部设置空气的排出口20c。
而且，根据本实施方式，热风供给单元50的吸气口51a与收容室100的后侧面101c以间隔状态对置，通过风扇52的工作，在收容室100内流通的空气被摄入吸气口51a。由此，能通过加热器53来加热通过来自热风供给单元50的热量而被加热的空气，因此能抑制加热器53的加热量，能抑制加热器53即全自动洗衣干衣机1的耗电量。
而且，根据本实施方式，通过来自外桶的热量而被加热的空气经过形成于收容室100的底面101a的第一开口部106、第二开口部107、第三开口部108以及第四开口部109，从机壳10与外桶20之间的空间被摄入收容室100内。由此，能将被进一步加热的空气摄入热风供给单元50的吸气口51a，能进一步抑制加热器53的加热量。
而且，根据本实施方式，在干衣过程中，紧接着将被加热器53加热的空气作为热风供给至外桶20内的加热烘干运转，进行将通过热风供给单元50、外桶20的余热而被加热的空气作为余热风供给至外桶20内的余热烘干运转。如此，能利用热风供给单元50、外桶20的余热来烘干洗涤物，因此，能抑制干衣过程中全自动洗衣干衣机1的耗电量。
以上，对本发明的实施方式进行了说明，但本发明不受上述实施方式的任 何限制，此外，本发明的实施方式除了上述以外，还可进行各种变更。
<变更例1>
图9是表示变更例1所涉及的全自动洗衣干衣机1的结构的主要部分剖视图。
在上述实施方式中，在外桶20的排出口20c的下游设有排气管道80。与此相对，在本变更例中，如图9所示，代替排气管道80，将用于对排出口20c进行开闭的开闭阀110设于排出口20c。开闭阀110基于控制部201的控制，在洗涤过程、漂洗过程、中间脱水过程以及最终脱水过程中关闭，在干衣过程中打开。在本变更例中，开闭阀110相当于本发明的排气部。
根据本变更例的结构，也与上述实施方式同样在洗衣时不会泄露蓄积于外桶20内的水，在干衣时能将从排出口20c流出来的空气排出。
<变更例2>
图10是表示变更例2所涉及的全自动洗衣干衣机1的结构的主要部分剖视图。
在本变更例中，如图10所示，在排气口83设有排气扇120。作为排气扇120，例如可以使用轴流扇。排气扇120基于控制部201的控制，在干衣过程中进行工作。
当采用本变更例的结构时，能将外桶20内的空气经过排出口20c强有力地摄入排气管道80内，因此，外桶20内的空气变得容易向排出口20c流动。由此，从上方送入外桶20内的热风变得越发容易行至洗涤脱水桶24的下部，因此能进一步期待干衣效率的提高。
<变更例3>
图11是变更例3所涉及的全自动洗衣干衣机1的侧剖图。
在上述实施方式中，空气从机壳10与外桶20之间的空间被摄入收容室100内，在收容室100内流动的空气被摄入热风供给单元50的吸气口51a。与此相对，在本变更例中，在外壳51A的下表面具有吸气口51a的热风供给单元50A配置于收容室100内。在收容室100内的底面101a，以与吸气口51a对置的方 式形成有连接于机壳10与外桶20之间的空间的空气摄入口130。在该结构中，空气从机壳10与外桶20之间的空间穿过空气摄入口130，被直接摄入热风供给单元50A的吸气口51a。空气摄入口130相当于本发明的开口。
根据本变更例的结构，也能将通过来自外桶20的热量而被加热的空气摄入热风供给单元50A，因此，与上述实施方式同样能抑制干衣过程中全自动洗衣干衣机1的耗电量。
<其他变更例>
在上述实施方式中，空气从机壳10与外桶20之间的空间穿过第一开口部106等，被摄入收容室100内。但是，也可以在偏离热风供给单元50的位置即收容室100的右侧面101e、后侧面101c处的右侧面101e的附近位置，设置全自动洗衣干衣机1的摄入外部空气的吸气口。在该情况下，穿过吸气口被摄入收容室100的外部空气在通过热风供给单元50的外壳51发出的热量而被加热后，被摄入热风供给单元50的吸气口51a。因此，这样的结构也能抑制干衣过程中全自动洗衣干衣机1的耗电量。
在上述实施方式中，在与机壳10的后表面对置的外桶20的侧面下部的位置设有排出口20c和排气管道80。但是，也可以在与机壳10的右侧面、左侧面对置的外桶20的侧面下部的位置设置排出口20c和排气管道80。此外，设有排出口20c的位置只要是外桶20的下部即可，排出口20c也可以不设置于外桶20的侧面而是设置于底面。
而且，在上述实施方式中，示例了具有以沿铅直方向延伸的旋转轴为中心进行旋转的洗涤脱水桶24的全自动洗衣干衣机1，但本发明也可以适用于具有以倾斜于铅直方向的旋转轴为中心进行旋转的洗涤脱水桶的全自动洗衣干衣机。
此外，本发明的实施方式可以在权利要求书所公开的技术思想的范围内适当地进行各种变更。
