Description

寝具烘干装置 技术领域
本发明涉及对被褥等寝具进行烘干的寝具烘干装置。
背景技术
下述专利文献1所记载的寝具类烘干机包括：箱体，在其内部形成有烘干室；以及载置构件，以能拉出的方式收纳于烘干室，载置寝具。在箱体的上部设有加热器和风扇。载置构件呈具有多个通孔的倒U字状。当寝具类烘干机开始烘干运转时，加热器和风扇工作。由此，外部空气从加热器后方的外部空气吸入口被取入后被加热而成为暖风，流入烘干室。暖风在烘干室内依次经过载置于载置构件的寝具的内部和载置构件的通孔而流入载置构件的内部空间后，从烘干室的侧壁下部的抽吸口到达排气管道而被排出机外。通过使暖风经过寝具的内部来促进寝具的烘干。
在烘干因具有厚度、湿气而导致通风即透气性差的寝具的情况下，在专利文献1的寝具类烘干机中，恐怕会因堵塞了通孔的寝具造成较大的阻力而妨碍流入烘干室的暖风经过寝具的内部从通孔流入载置构件的内部空间。当像这样暖风的风量减少时，难以提高寝具的烘干效率。

发明内容
发明所要解决的问题
本发明是在该背景的基础上完成的发明，目的在于提供一种能够谋求提高 寝具的烘干效率的寝具烘干装置。
用于解决问题的方案
本发明是一种寝具烘干装置，包括：装置主体，具有烘干室、送风部以及加热部，所述送风部向所述烘干室送风，所述加热部对所述送风部所产生的风进行加热而形成暖风；台车，具有安置部并以能拉出的方式收纳于所述烘干室，所述安置部设有表面部和中空部分，所述表面部供寝具以山形折叠状态放置并形成有通气孔，所述中空部分成为流入所述烘干室并经过所述通气孔的风的通道的中空部分；流入温度检测部，检测前往所述烘干室的空气的温度或所述烘干室内的温度来作为流入温度；以及控制部，执行使所述送风部和所述加热部工作来向所述烘干室内的寝具吹拂暖风的烘干运转，在所述烘干运转中，所述控制部根据所述流入温度检测部的检测结果来控制所述送风部，由此调整风势。
此外，本发明的特征在于，当所述流入温度或所述流入温度的上升程度为第一阈值以上时，所述控制部控制所述送风部使得风势增强。
此外，本发明的特征在于，所述寝具烘干装置还包括：流出温度检测部，检测经过所述中空部分并从所述烘干室流出的空气的温度来作为流出温度，在所述烘干运转中，所述控制部根据所述流出温度检测部的检测结果来控制所述送风部，由此调整风势。
此外，本发明的特征在于，当所述流出温度或所述流出温度的下降程度为第二阈值以下时，所述控制部控制所述送风部使得风势减弱。
发明效果
根据本发明，在寝具烘干装置中，当以在安置部的表面部放置有山形折叠状态的寝具的台车被收纳于装置主体的烘干室的状态开始烘干运转时，控制部使送风部和加热部工作。由此，流入烘干室的暖风会在从表面部的通气孔流过安置部的中空部分时经过寝具的内部，因此能烘干寝具。烘干运转中的控制部根据流入温度检测部所检测的流入温度即前往烘干室的空气的温度或烘干室内的温度来控制送风部，由此调整风势。流入温度是经过安置部的通气孔之前的暖风的温度，根据寝具的通风而变化。因此，当寝具的通风差时，流入温度上升。在烘干运转中，根据流入温度被调整为最佳势头的暖风吹拂向烘干室内的 寝具，因此即使是通风差的寝具，该暖风也能顺畅地经过寝具的内部。因此，寝具烘干装置能够谋求提高寝具的烘干效率。
此外，根据本发明，当由于寝具的通风差而导致流入温度或流入温度的上升程度为第一阈值以上时，控制部控制送风部使得风势增强。由此，强势的暖风吹拂向烘干室内的寝具，因此该暖风能顺畅地经过通风差的寝具的内部。因此，寝具烘干装置能够谋求提高寝具的烘干效率。
此外，根据本发明，烘干运转中的控制部根据流出温度检测部所检测的流出温度即经过放置于安置部的寝具的内部和安置部的中空部分从烘干室流出的空气的温度来控制送风部，由此调整风势。流出温度根据寝具的通风而变化。因此，当寝具的通风良好时，从烘干室强势地流出空气，由此流出温度降低。在烘干运转中，根据流出温度被调整为最佳势头的暖风吹拂向烘干室内的寝具，因此寝具烘干装置能够谋求提高寝具的烘干效率。
此外，根据本发明，当由于寝具的通风良好而使得流出温度或流出温度的下降程度为第二阈值以下时，控制部控制送风部使得风势减弱。由此，由于弱势而缓慢地经过加热部而更得更高温的暖风吹拂向烘干室内的寝具，因此，寝具烘干装置能够谋求进一步提高寝具的烘干效率。

具体实施方式
以下，参照附图对本发明的实施方式进行具体说明。图1是本发明的一个实施方式的寝具烘干装置1的示意性纵剖右视图。将图1中与纸面正交的方向称为寝具烘干装置1的左右方向X，将图1中的左右方向称为寝具烘干装置1的前后方向Y，将图1中的上下方向称为寝具烘干装置1的上下方向Z。左右方向X当中，将图1的纸面的里侧称为左侧X1，将图1的纸面的表侧称为右侧X2。前后方向Y当中，将左侧称为前侧Y1，将右侧称为后侧Y2。上下方向Z当中，将上侧称为上侧Z1，将下侧称为下侧Z2。左右方向X和前后方向Y是横向的一例。横向是水平方向或相对于水平方向少许倾斜的大致水平方向。上下方向Z是纵向。纵向是铅垂方向或相对于铅垂方向少许倾斜的大致铅垂方向。
本实施方式的寝具烘干装置1用作商业用途，设置于自助洗衣店等。寝具烘干装置1包括：装置主体2，形成寝具烘干装置1的箱体；以及台车3，配置在装置主体2内，放置被褥、床垫等寝具P。装置主体2呈左右方向X上扁平而纵长的盒状。装置主体2具有：左右一对侧壁4、底壁5、顶壁6、后壁7、前壁8以及门9。左右一对侧壁4是各自纵向延伸的板，平行配置。底壁5是水平延伸的板，架设在一对侧壁4的下端之间。顶壁6是水平延伸的中空体，架设在一对侧壁4的上端之间。后壁7是纵向延伸的中空体，架设在一对侧壁4的后端之间，也架设在底壁5和顶壁6的后端之间。前壁8是左右方向X上长而纵向延伸的中空体，架设在一对侧壁4的上端部的前端之间，连接于顶壁6的前端。
在装置主体2的正面部即前表面部形成有由一对侧壁4的前端、底壁5的前端以及前壁8的下端包边的纵长的出入口2A。门9是具有与出入口2A大致相同的大小的纵长的板，经由铰链10(参照图4)连结于一方的侧壁4，例如右侧X2的侧壁4。门9能够在关闭出入口2A的闭位置(参照图1和图4)与打开出入口2A的开位置(参照图3)之间以铰链10为中心进行转动。为了开闭 门9，在处于闭位置的门9的前表面部设有供使用者握持的把手11。在装置主体2的内部设有由一对侧壁4、底壁5、顶壁6、后壁7、前壁8以及闭位置的门9包围的烘干室2B。烘干室2B是占装置主体2的大部分体积的盒状的空间。在门9处于开位置的状态下，烘干室2B从出入口2A向前侧Y1露出。也可以是，为了能够从机外观察烘干室2B，门9的至少一部分由玻璃等透明或半透明地构成。
在顶壁6的后表面部设有面向机外即装置主体2之外的吸气口6A，在顶壁6的下表面部设有面向烘干室2B的入口6B，在顶壁6的上表面部设有面向机外的排气口6C。在后壁7的前表面部的下部设有面向烘干室2B的出口7A。装置主体2包括：吸气路12，在顶壁6内从吸气口6A向前侧Y1延伸后向下侧Z2折曲并与入口6B相连；以及排气路13，在后壁7内从出口7A向上侧Z1延伸后在顶壁6内向前侧Y1、上侧Z1延伸并与排气口6C相连。需要说明的是，虽然图1中看起来排气路13中途被吸气路12切断，但实际上排气路13并未在中途被切断，而是从出口7A延伸到排气口6C。
装置主体2具有：由风扇等构成的送风部14，配置于排气路13；以及由燃烧器等构成的加热部15，配置于吸气路12。当通过风扇旋转而使送风部14工作时，烘干室2B、吸气路12以及排气路13呈负压状态。由此，外部空气如黑箭头所示从吸气口6A被取入吸气路12，从入口6B流入烘干室2B，然后从出口7A流出至排气路13，从排气口6C排出机外。当加热部15在像这样送风部14工作而向烘干室2B送风的状态下工作时，从吸气口6A被取入吸气路12的外部空气即送风部14所产生的风会被加热部15加热而成为暖风，并在供给至烘干室2B后流过排气路13而从排气口6C排出机外。
台车3收纳于烘干室2B。台车3具有：基部21；以及安置部22，设于基部21上，放置寝具P。基部21呈上下方向Z上扁平的盒状，在前后方向Y上具有与烘干室2B大致相同的尺寸。基部21具有：左右一对侧壁23；前壁24，架设在一对侧壁23的前端之间；以及后壁25，架设在一对侧壁23的后端之间。基部21具有：下壁26，架设在一对侧壁23的下端之间，也架设在前壁24和后壁25的下端之间；以及上壁27，架设在一对侧壁23的上端之间，也架设在前壁24和后壁25的上端之间。
侧壁23、前壁24以及后壁25各自为纵向延伸的矩形的板，下壁26和上壁27各自为水平延伸的矩形的板。基部21具有由一对侧壁23、前壁24、后壁25、下壁26以及上壁27包围的内部空间21A。后壁25设有与内部空间21A相连的取出口25A。下壁39的下表面部的四角设有车轮28。上壁27设有与内部空间21A相连的取入口27A。
也参照作为寝具烘干装置1的示意性纵剖主视图的图2，安置部22具有从基部21的上壁27向上侧Z1突出的山形的整体形状。安置部22在前后方向Y上具有略小于基部21但与烘干室2B大致相同的尺寸。本实施方式中仅设置一个安置部22，但也可以设置多个安置部22并将多个安置部22以在基部21上沿左右方向X排列的方式配置。安置部22具有：主体部29，实际放置寝具P；以及前后一对端壁部30，配置在前后方向Y上的主体部29的两侧。主体部29在主视时具有上下颠倒的倒U字状或倒V字状的剖面。在前侧Y1的端壁部30的前表面部的上部设有把手31(参照图3)。
安置部22具有设于主体部29的外表面部的许多通气孔22A。通气孔22A分布在主体部29的整个区域。各端壁部30是呈向上侧Z1突出的山形的板，前后一对端壁部30以将主体部29的前端缘和后端缘分别包边的方式固定于主体部29。安置部22具有由基部21的上壁27、主体部29以及前后一对端壁部30包围的山形的内部空间22B。各通气孔22A和上壁27的取入口27A处于与内部空间22B连通的状态。
设有通气孔22A的主体部29的外表面部是安置部22的表面部22C。表面部22C具有：半圆弧状的顶部区域22CA，向上侧Z1膨出；左区域22CB，从顶部区域22CA的左下端向左下侧延伸到上壁27；以及右区域22CC，从顶部区域22CA的右下端向右下侧延伸到上壁27。左区域22CB和右区域22CC各自在本实施方式中为平坦的倾斜面，但也可以至少局部为弯曲面。通气孔22A分布在左区域22CB和右区域22CC各自的整个区域。
如图3所示，在门9处于开位置的状态下，这样的台车3能够从装置主体2的烘干室2B向前侧Y1拉出。使用者在拉出、收纳台车3时握持把手31。使用者将对折过的寝具P安置于拉出后的台车3的安置部22。此时，寝具P以沿着安置部22的主体部29山形折叠的状态放置于安置部22的表面部22C，将主体 部29的通气孔22A堵塞。然后，当使用者将台车3从装置主体2的出入口2A推入烘干室2B进行收纳时，收纳状态的台车3配置在装置主体2的底壁5上。
在底壁5的上表面部设有分别承接台车3的左右车轮28的左右一对导轨32(参照图2)。通过使各车轮28由导轨32承接，台车3在烘干室2B内在左右方向X上被定位。如图4所示，当使用者将门9关闭至闭位置时，在烘干室2B内的台车3中，基部21被夹持在装置主体2的后壁7与门9之间，因此，如图1所示，台车3在前后方向Y上被定位。安置部22放置有寝具P的台车3处于如上所述寝具P将主体部29的通气孔22A堵塞的状态，处于基部21的后壁25的取出口25A与装置主体2的后壁7的出口7A相连的状态。
寝具烘干装置1还包括流入温度检测部33、流出温度检测部34、控制部35以及风量检测部36。
流入温度检测部33和流出温度检测部34可以采用公知的温度传感器、恒温器等开关。作为流入温度检测部33的一个例子的流入温度检测部33A配置在吸气路12中的加热部15与入口6B之间。该情况下的流入温度检测部33A在吸气路12内检测前往烘干室2B的空气的温度来作为流入温度。作为流入温度检测部33的另一例子的流入温度检测部33B配置在烘干室2B内例如顶壁6的下表面部。该情况下的流入温度检测部33B检测烘干室2B内的温度来作为流入温度。也可以是，不只设置流入温度检测部33A和流入温度检测部33B中的一方，而是设置双方。流出温度检测部34在排气路13中配置于例如比送风部14靠烘干室2B侧的上游区域13A。流出温度检测部34检测从烘干室2B流出并流过排气路13的空气的温度来作为流出温度。
控制部35由微机等构成，内置于装置主体2。控制部35分别与送风部14和加热部15电连接，控制部35控制这些电气元件，执行烘干室2B内的寝具P的烘干运转。此外，流入温度检测部33和流出温度检测部34各自的检测结果即流入温度和流出温度被实时地输入至控制部35。风量检测部36是检测流过装置主体2内的空气的风量的公知的传感器，例如配置于排气路13内的排气口6C的附近。风量检测部36的检测结果即风量被实时地输入至控制部35。
在安置部22放置有寝具P的台车3收纳于烘干室2B且门9关闭的状态下，控制部35执行烘干运转。图5是示出烘干运转的流程图。图6是示出烘干运转 中的流入温度的经时变化的曲线图。图7是示出烘干运转中的流出温度的经时变化的曲线图。在图6和图7中，横轴表示经过时间，纵轴表示流入温度或流出温度。
当烘干运转开始时(参照图6和图7的定时t0)，控制部35使送风部14和加热部15工作。此时，从吸气口6A被取入吸气路12并被加热部15加热过的外部空气即暖风从入口6B流入烘干室2B，在烘干室2B内吹拂向山形折叠的寝具P。烘干运转的开始时刻的送风部14的转速固定为规定的设定值。
在烘干室2B内吹拂至寝具P的暖风经过寝具P的内部到达主体部29的通气孔22A，从通气孔22A流入安置部22的内部空间22B。流入内部空间22B内的暖风向基部21的内部空间21A流下，经过取出口25A和出口7A向排气路13流出，从排气口6C排出机外。像这样，作为流入烘干室2B并经过寝具P和通气孔22A的暖风的通道，内部空间22B是设于安置部22的中空部分。并且，流入烘干室2B的暖风在从安置部22的表面部22C的通气孔22A流过安置部22的内部空间22B时会经过寝具P的内部，因此能烘干寝具P。
通过事先进行的实验等，针对流入温度检测部33的检测结果即流入温度确定第一阈值，针对流出温度检测部34的检测结果即流出温度确定第二阈值。第一阈值的一个例子是165度，第二阈值的一个例子是70度。需要说明的是，与上述流入温度检测部33A所检测的流入温度有关的第一阈值和与上述流入温度检测部33B所检测的流入温度有关的第一阈值既可以相同也可以不同。在烘干运转中，当因装置主体2内的空气流动变差而导致风量检测部36的检测结果低于规定的阈值时，控制部35判断为产生了风量降低故障，使送风部14和加热部15停止。
在烘干运转中，暖风的风量不限于始终固定，控制部35根据流入温度来控制送风部14，由此调整风势即风量。具体而言，流入温度是经过安置部22的通气孔22A之前的上游侧的暖风的温度，根据放置于安置部22的寝具P的通风而变化。例如，当寝具P的通风差(含有许多湿气的状态)时，暖风在上游侧滞留，因此流入温度会上升。因此，当如图6的定时t1所示流入温度为第一阈值以上时(步骤S1中为“是”)，控制部35通过将送风部14的风扇的转速从上述设定值提高例如20％来控制送风部14使得风势增强(步骤S2)。由此，当 从定时t1起经过一段时间时，流入温度会降低至目标温度(参照图6)。需要说明的是，也可以不针对流入温度本身，而是针对流入温度的上升程度、例如每分钟的流入温度的上升速度来确定第一阈值，在步骤S1中，控制部35判断流入温度的上升程度是否为第一阈值以上。
像这样，通过步骤S2，根据流入温度被调整为最佳势头的暖风即强势且风量大的暖风吹拂向烘干室2B内的寝具P，因此即使是通风差的寝具P，该暖风也能顺畅地经过寝具P的内部。因此，寝具烘干装置1能抑制风量降低故障而持续烘干运转，因此能够谋求提高寝具P的烘干效率。
然后，也可以是，在烘干运转中，控制部35根据经过安置部22的内部空间22B并从烘干室2B流出的下游侧的空气的温度即流出温度来控制送风部14，由此调整风势。具体而言，流出温度根据寝具P的通风而变化。因此，例如当由于烘干推进而使得寝具P的通风变得良好时，会从烘干室2B强势地流出空气，由此流出温度会降低。或者，对于烘干运转开始前的状态下已然通风良好的寝具P而言，有可能即使在烘干运转的初始阶段流出温度也降低。由此，当如图7的定时t2所示流出温度为第二阈值以下时(步骤S3中为“是”)，控制部35通过将送风部14的风扇的转速从上述设定值降低例如20％来控制送风部14使得风势减弱(步骤S4)。由此，暖风的风势减弱而不易经过寝具P，在定时t2之后流出温度上升(参照图7)。需要说明的是，也可以不针对流出温度本身，而是针对流出温度的下降程度、例如每分钟的流出温度的下降速度来确定第二阈值，在步骤S3中，控制部35判断流出温度的下降程度是否为第二阈值以下。
像这样，根据流出温度被调整为最佳势头的暖风即由于弱势而缓慢地经过加热部15变得更高温的风量小的暖风吹拂向烘干室2B内的寝具P，因此寝具烘干装置1能够谋求提高寝具P的烘干效率。
并且，从烘干运转开始起到经过规定的运转时间为止(步骤S5中为“否”)，控制部35反复进行步骤S1～S4的处理。当经过运转时间时(步骤S5中为“是”)，控制部35通过使送风部14和加热部15停止来结束烘干运转。
本发明不限于以上说明的实施方式，能够在技术方案所记载的范围内进行各种变更。
例如，也可以是，如图3所示，台车3设有按压构件41，所述按压构件41为了将寝具P维持为山形折叠状态而按压于安置部22。按压构件41一一设置在台车3的基部21的上壁27中的安置部22的左右两侧。各按压构件41例如由弯折成M字状的管构成。也可以是，各按压构件41始终被设于基部21内的弹簧等施力构件(未图示)以接近安置部22的方式施力。
此外，也可以是，如图1所示，台车3设有间隔构件42。间隔构件42的一个例子为在上下方向Z上延伸的肋。多个间隔构件42以在安置部22的表面部22C的左区域22CB和右区域22CC中分别沿前后方向Y排列的方式配置。当寝具P放置在表面部22C时，在各间隔构件42的周围，特别是在前后方向Y上的各间隔构件42的两侧的寝具P与表面部22C之间形成有间隙Q(参照图2)。间隙Q与表面部22C中的最近的通气孔22A连通，因此该通气孔22A不会被寝具P堵塞。此外，间隙Q也与烘干室2B连通。因此，即使放置在安置部22的表面部22C的寝具P的通风差，暖风也能经过间隙Q和最近的通气孔22A顺畅地流过烘干室2B和安置部22的内部空间22B。因此，寝具烘干装置1能够通过确保暖风的风量来谋求提高寝具P的烘干效率。
