请一并参阅图1～图5，本发明实施方式的洗碗机的干燥系统100包括内胆10、换热装置20、第一风道30、第二风道40及切换装置50。
第一风道30连通内胆10及换热装置20，第二风道40连通换热装置20与外界大气。换热装置20安装在内胆10外。换热装置20内设置有第一流道21及第二流道22。第一风道30上设置有第一风机31。第二风道40上设置有第二风机41。切换装置50用于将第一流道21交替地与第一风道30和第二风道40连通，及用于将第二流道22交替地与第二风道40和第一风道30连通。
在本发明实施方式的洗碗机的干燥系统100中，换热装置20内的第一流道21及第二流道22可分别交替地与第一风道30及第二风道40连通，使得第一流道21和第二流道22是交替地流过湿热空气和冷空气，使得湿热空气中的水分在换热装置20内逐渐冷凝去除，从而可实现内胆10内的高效干燥。
具体地，在本发明实施方式中，第一风道30为热风道，内胆10、换热装置20、第一风道30构成第一循环回路，第一风机31驱动内胆10内的湿热空气在第一循环回路内流动。
第二风道40为冷风道，换热装置20及第二风道40构成第二循环回路，第二风机41驱动冷空气在第二循环回路内流动。如此，实现湿热空气及冷空气的循环流动。
在本发明实施方式中，第一流道21的设置的数目为一个，第二流道22的设置的数目为一个，第一流道21与第二流道22间隔设置，以防止两个流道相互接触而影响换热效果。
需要说明的是，第一流道21的设置数目及第二流道22的设置数目可以根据具体应用情况进行设置，并不仅仅限于本实施方式中的设置数目。
在一个实施方式中，内胆10开设有第一通风口11及第二通风口12。第一风道30包括第一子风道32及第二子风道33。第一子风道32连接第一通风口11及换热装置20。第二子风道33连接第二通风口12及换热装置20。
如此，第一风道30的两个子风道的设置可延长气流循环流动的时间，从而提升换 热效果，并且第一风道30与内胆10的连接方式较为简单，易于实现气流的循环流动。
具体地，在本发明实施方式中，第一通风口11及第二通风口12开设在内胆10的两侧，例如在附图1所示的方位中，第一通风口11开设在内胆10的左侧，第二通风口12开设在内胆10的右侧。第一子风道32及第二子风道33均为热风道，第一风机31驱动湿热空气在第一子风道32及第二子风道33内流动。换热装置20位于第一子风道32及第二子风道33之间。内胆10、第一子风道32、换热装置20及第二子风道33构成第一循环回路。
在一个实施方式中，第一风机31设置在第二子风道33上。
如此，第一风机31靠近第二子风道33设置，利于实现气流的充分流动。
第一风机31工作时，将热湿空气从内胆10内抽进第一子风道32并进入换热装置20，热换后的空气从换热装置20进入第二子风道33，再经第二子风道33进入内胆10内，如此循环，使得内胆10内的热湿空气被干燥冷却。
将第一风机31设置在第二子风道33上的好处是，由于第二子风道33内的空气温度及湿度较第一子风道32内的空气温度及湿度低，第一风机31将较低温度及湿度的空气直接送入内胆10内，增强了进入内胆10内的空气流速，从而有利于加快内胆10的干燥速度。
需要说明的是，在其他实施方式中，第一风机31可设置在其他合适的位置，例如设置在第一子风道32上。即为第一风机31的设置方式可以根据实际应用情况进行对应调整。
在一个实施方式中，第二风道40与换热装置20位于内胆10的同一侧。
如此，第二风道40靠近换热装置20，外界大气的冷空气可较为快速地由第二风道40通过换热装置20，从而提升干燥速度。
在一个实施方式中，洗碗机的干燥系统100包括进口13及出口14。第二风道40包括第三子风道42及第四子风道43。进口13连通外界大气。第三子风道42连通进口13及换热装置20。出口14连通外界大气。第四子风道43连通出口14及换热装置20。
如此，第二风道40的两个子风道的设置可保证湿热空气与冷空气充分换热，从而提升换热效果，并且第二风道40与外界空气及换热装置20的连接方式较为简单，易于实现气流的循环流动。
具体地，在本发明实施方式中，进口13及出口14开设在内胆10的同一侧，例如在附图1所示的方位中，进口13及出口14均开设在内胆10的右侧。第三子风道42及第四子风道43均为冷风道，第二风机41驱动外界冷空气在第三子风道42及第四子风道43内流动。换热装置20位于第三子风道42及第四子风道43之间。内胆10、第三子 风道42、换热装置20及第四子风道43构成第二循环回路。
在一个实施方式中，第二风机41设置在第三子风道42上。
如此，第二风机41靠近进口13，利于充分地将外界大气的冷空气带入第三子风道42内，从而保证换热的充分性。
第二风机41工作时，将外界冷空气抽进第三子风道42并进入换热装置20，换热后的空气从换热装置20进入第四子风道43，再经第四子风道43排出至外界大气，如此循环，使得换热装置20内的热量被冷空气带出，以完成热交换。
将第二风机41设置在第三子风道42上的好处是，由于第三子风道42内的空气温度及湿度较第四子风道43内的空气温度及湿度低，第二风机41将外界冷空气直接送入换热装置20内，增强了进入换热装置20内的空气流速，从而有利于提高换热装置20的热交换效率。
需要说明的是，在其他实施方式中，第二风机41可设置在其他合适的位置，例如设置在第四子风道43上。即为第二风机41的设置方式可以根据实际应用情况进行对应调整。
在一个实施方式中，请参阅图3、图4及图5，换热装置20开设有第一进口23、第二进口24、第一出口25及第二出口26。第一流道21连通第一进口23及第一出口25。第二流道22连通第二进口24及第二出口26。切换装置50包括第一切换件51及第二切换件52。第一切换件51设置在第一进口23及第二进口24处。第二切换件52设置在第一出口25及第二出口26处。
当第一切换件51在第一位置及第二切换件52在第二位置时(如图3所示的位置)，第一流道21与第一风道30连通，及第二流道22与第二风道40连通。当第一切换件51在第三位置及第二切换件52在第四位置时(如图4所示的位置)，第一流道21与第二风道40连通，及第二流道22与第一风道30连通。
如此，切换装置50靠近换热装置20设置，可通过第一切换件51及第二切换件52在不同位置的交替切换，较为简单地实现第一流道21和第二流道22交替地流过湿热空气和冷空气，从而可充分实现湿热空气及冷空气的循环换热及流动。
具体地，在本发明示例中，第一流道21与第二流道22相互间隔设置，第一切换件51及第二切换件52均为切换阀门，第一切换件51可在第一位置及第三位置之间交替切换，第二切换件52可在第二位置及第四位置之间交替切换。当第一切换件51在第一位置及第二切换件52在第二位置时，第一流道21连通第一子风道32及第二子风道33，及第二流道22连通第三子风道42及第四子风道43。当第一切换件51在第三位置及第二切换件52在第四位置时，第一流道21连通第三子风道42及第四子风道43，及第二 流道22连通第一子风道32与第二子风道33。
在一个实施方式中，第一切换件51在第一位置及第三位置之间交替切换的时间与第二切换件52在第二位置及第四位置之间交替切换的时间相同。
如此，实现了两个切换件的同步交替切换，使得湿热空气及冷空气可及时地进入换热装置20的流道内以实现充分换热，并可及时地由流道流出，以保证充分换热的有效性及持续性。
在一个实施方式中，交替切换的时间间隔为5秒至5分钟。如此，交替切换的时间间隔适中，可获得较好的干燥效果。
在一个实施方式中，交替切换的时间间隔为30秒至120秒。如此，交替切换的时间间隔适中，既可以保证较佳的干燥效果，又可使得干燥时间较短。
在一个实施方式中，洗碗机的干燥系统100包括控制装置60。控制装置60连接切换装置50，并用于控制切换装置50将第一流道21交替地与第一风道30和第二风道40连通，及将第二流道22交替地与第二风道40和第一风道30连通。
如此，通过可控制装置60较为简单地实现切换装置50的交替切换，并且利于洗碗机的干燥系统100的自动化及集成化设计。
具体地，在本发明示例中，控制装置60控制第一切换件51及第二切换件52的位置变换，使得第一流道21交替地与第一风道30和第二风道40连通，及使得第二流道22交替地与第二风道40和第一风道30连通。
在本发明实施方式中，洗碗机的干燥系统100的工作过程包括：在干燥阶段时，第一风机31和第二风机41持续工作，第一风机31驱使湿热空气从内胆10抽出，湿热空气流经第一子风道32进入换热装置20，在换热装置20内冷凝，接着从换热装置20流出并经过第二子风道33返回内胆10内。第二风机41吸入外界大气的冷空气，冷空气经第三子风道42进入换热装置20内，冷空气在换热装置20内与湿热空气进行换热冷凝，接着热交换后的冷空气从换热装置20出来并经过第四子风道43流出。
具体地，在换热装置20内，当第一切换件51在第一位置和第二切换件52在第二位置时，湿热空气流经第一流道21并在第一流道21的内壁上冷凝，同时外界大气的冷空气流过第二流道22，对第二流道22进行冷却并带走由湿热空气冷凝而来的并附着在第二流道22的内壁上的水珠(如图3所示)。
然后，控制装置60控制第一切换件51从第一位置切换至第三位置，和控制第二切换件52从第二位置切换至第四位置，此时湿热空气流经第二流道22并在第二流道的内壁上冷凝，外界大气的冷空气转而流过第一流道21，对第一流道21进行冷却并带走附着在其内壁上的水珠(如图4所示)。如此类推，通过第一切换件51和第二切换件52 的不断交替切换，第一流道21和第二流道22都是交替地流过湿热空气和冷空气，从而使得湿热空气中水分在两个流道内逐渐冷凝去除，从而实现内胆10内的高效干燥。
本发明实施方式的洗碗机1000包括上述任一实施方式的洗碗机的干燥系统100。
在本发明实施方式的洗碗机1000中，换热装置20内的第一流道21及第二流道22可分别交替地与第一风道30及第二风道40连通，使得第一流道21和第二流道22是交替地流过湿热空气和冷空气，使得湿热空气中的水分在换热装置20内逐渐冷凝去除，从而可实现内胆10内的高效干燥。
请参阅图6及图7，在本发明实施方式中，洗碗机1000为柜式洗碗机。洗碗机1000包括门体200。内胆10与门体200连接以形成封闭的洗涤腔室。内胆10内布置有第一层碗篮15和第二层碗篮16，第一层碗篮15位于第二层碗篮16之上。第一层碗篮15的下侧设置有第一喷臂151，第二层碗篮16的下侧设置有第二喷臂161。第一喷臂151和第一喷臂161均与内水管路17连通。如此，可以通过两个喷臂分别实现对两层碗篮的清洗。
在本发明实施方式中，内胆10的底侧设有水杯18。水杯18连接洗涤泵19。洗涤泵19连接通内水管路17。如此，可通过洗涤泵19将水输送至两个喷臂，以实现清洗，并可通过水杯18收集洗涤后的水。
具体地，请参阅图7，在洗涤阶段时，洗涤泵19通过内水管路17输送水到第一喷臂151和第一喷臂161(如图7箭头所示)，第一喷臂151和第一喷臂161均通过一边旋转一边喷射水以分别实现对第一层碗篮15及第二层碗篮16内的餐具的清洗。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
