为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。
图1为根据本公开实施例提供的吸油烟机的结构示意图。
图2为根据本公开实施例提供的挡板的正投影和锅的正投影之间的位置关系示意图。
图3为根据本公开实施例的冷凝装置的结构示意图。
具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
传统的吸油烟机存在着三个突出的缺陷：
一是油烟吸净率低，远不能满足人们对家居空气质量的要求。科学研究确认，厨房油烟污染容易造成呼吸道疾病，而且厨房油烟是肝癌、鼻咽癌等恶性肿瘤的风险因素。虽然近年来众多专家推出了各式各样的新型吸油烟机，但油烟吸净率低的状况并未得到根本改善。厨房油烟吸净率低的主要原因是炒菜时的油烟是向四周扩散的，传统的顶吸式吸油烟机工作时，只有部分上升的油烟能进入吸油烟机被排出，其余的油烟就会四处蔓延。如果希望从一个方向将它吸走，需要很大的吸力，而很大的吸力就会产生很大的噪音，这也是不可接受的。
二是吸油烟机内的油污严重，难以清洗。吸油烟的核心部件是离心式抽风机。热油烟进入机内后，先经过挡板，过滤网等部件，然后经抽风机和叶轮离心力的作用从排气管排 出，随着吸油烟机使用时间的延长，叶轮上将沾满油污。叶轮沾满油污后会发生震动，噪音等，致使能耗增加，使用寿命缩短。然而，叶轮的清洗需要把整个机子卸下并且拆开，费工费时，十分麻烦。
三是从排气管排出的油烟废气未经任何处理而直接排入大气中，这些油烟废气会造成环境污染。厨房油烟已是整个地球大气层的最重要污染源之一，许多国家已把实现厨房废气对外零排放作为环保目标。
为了解决以上问题，本公开实施例提供一种吸油烟机。图1为根据本公开实施例提供的吸油烟机的结构示意图。如图1所示，该吸油烟机包括：高速气流发生装置和吸滤排管道系统，其中，高速气流发生装置用于产生高速气流，高速气流自上而下地流动并且直抵灶台23以形成高速气流幕18，灶台23上设置有锅19，高速气流幕18围绕锅19，这样，高速气流幕18可以将由锅19产生的油烟与外界隔绝，从而避免油烟向四周扩散。如图1所示，吸滤排管道系统包括挡板1，挡板1位于锅19的上方，挡板1和高速气流幕18之间形成拢烟区域，位于该拢烟区域中的油烟被吸滤排管道系统吸入，然后被过滤、排出。
在上述实施例的吸油烟机中，通过在锅19的四周形成高速气流幕18，且高速气流幕18自上而下喷出，可将锅19产生的油烟与外界阻隔，避免油烟向外界周围扩散。而且，高速气流幕18和挡板1一起形成一“气罩”，该气罩可将锅19和灶台23盖住，使气罩中的油烟被罩住而无法向外扩散，同时被吸滤排管道系统抽走。这种“先罩住再吸排”的吸烟方式可提高油烟吸净率，使居室内废气净化率大幅提升。与现有吸油烟机相比，本公开实施例的吸油烟机省去了挡油板、废气箱等部件，因此，简化了吸油烟机的结构，降低成本和能耗，同时机内油污情况也得到有效改善。
例如，高速气流发生装置包括环形气体增压仓13和设置于环形气体增压仓13上的喷气口14，高速气流从喷气口14射出。将气体增压仓13设置为环形，有利于在锅19的周围一圈产生高速气流幕18。至少一个示例中，该高速气流幕18与锅19之间留有一段距离，这样可以罩住尽可能多的油烟。
例如，环形气体增压仓13具有环形唇状喷气口14，以使从环形唇状喷气口14喷出的高速气流形成圆筒状高速气流幕18。至少一个示例中，气体增压仓13的底部具有一圈对着灶台23的狭窄缝隙，即环形唇状喷气口14。
例如，高速气流发生装置还包括与气体增压仓13连接的充气装置，充气装置用于向气体增压仓13内充入加压气体。至少一个示例中，该充气装置为微型气泵17，气体增压仓13上有一进气孔15，该进气孔15通过管子16和一微型气泵17相连接。高速气流发生 装置包括微型气泵17、增压仓13和喷气口14。当吸油烟机工作时，微型气泵17所产生的气体不断输到气体增压仓13，增压后所产生的高压气体从喷气口14不断喷出，沿着锅19的外围形成高速气流幕18。这里所谓“高速”只是相对而言，一般烹饪油烟废气为稀薄轻飘的热气，不形成强气流，在方位上也不会和气流幕迎面接触，所以即使速度较低的气流幕也能将油烟废气困住，不使外泄。
例如，吸滤排管道系统的形状呈倒置漏斗，倒置漏斗包括渐缩的杯状部分和管状部分。渐缩的杯状部分用作挡板1，管状部分位于挡板1的中心位置并且用作进风管24，进风管24具有进风口3，位于高速气流幕18中的油烟从进风口3进入进风管24。如图1所示，沿竖直方向，杯状部分从下到上在横向宽度上逐渐缩小，这样有利于聚拢油烟，并且将油烟导向到进风口3。管状部分位于挡板的中心位置并且与杯状部分连接，这样能高效率地抽走位于锅19上方的油烟。管状部分的横向宽度基本上不变且沿竖直方向延伸，这样不仅便于过滤装置和/或冷却系统的安装拆卸，也有利于导烟。
例如，气体增压仓13固定安装于挡板1且环绕挡板1的外周边缘20，锅19在灶台23所在平面上的正投影位于挡板1的外周边缘20在灶台23所在平面上的正投影。至少一个示例中，锅19在灶台23所在平面上的正投影和挡板1的外周边缘20在灶台23所在平面上的正投影完全重叠，或者，锅19在灶台23所在平面上的正投影落入挡板1的外周边缘20在灶台23所在平面上的正投影中，本申请对此不作限制。如图2所示，在锅19在灶台23所在平面上的正投影落入挡板1的外周边缘20在灶台23所在平面上的正投影中的情况下，挡板1的正投影面积大于锅19的正投影面积，这样更能使挡板1拢住由锅19产生的所有烹饪油烟，避免外漏，从而有利于提高油烟吸净率，因此，该情况为优选实施方式。
例如，挡板1的边缘部分向内(即向挡板1的中心位置)卷曲成沟状以形成槽2，槽2用于收集挡板1上的油液。例如，在吸油烟机工作时，烹饪产生的油烟中混杂有水汽、油汽，当油烟碰撞到挡板1下表面时，因冷凝产生污水，由于挡板1的下表面为倾斜的，该污水可沿着挡板1滴入至挡板1的边缘部分形成的槽2中。这样，污水可被收集到槽2中，从而避免滴到灶台或锅上。进一步地，至少一个示例中，该槽2可连接一污水收集器，污水通过槽2流入至污水收集器中，这样便于拆卸和清理污水。
例如，吸滤排管道系统还包括设置于进风口3处的第一网格状隔板21和设置在进风管24中的冷凝装置，冷凝装置用于冷凝通过第一网格状隔板21进入进风管24中的油烟。如图1所示，进风管24最下方是圆形的进风口3，进风管24的下部从下到上依次设置有 冷凝装置和过滤装置。
例如，冷凝装置包括冷凝杯7。例如，冷凝杯7内设置有盘旋成圆柱体的塑料管8，塑料管8内盛有冷凝液。例如，所述冷凝杯7具有靠近进风口一侧的的底部，该底部具有网格状，这样有利于油烟从该底部进入冷凝杯中。例如，为了便于冷凝杯的安装固定，冷凝杯7放置在第一网格状隔板21上，由第一网格状隔板21支撑。冷凝杯7的作用是把废水汽、废油汽冷凝并且排出，尽量减少进入过滤杯9中的油烟。至少一个示例中，第一网格状隔板21具有多孔结构，这样透气性好，有利于油烟进入冷凝杯7中。例如，第一网格状隔板21可由非金属材料制成，非金属材料例如为诸如塑料等有机材料。至少一个示例中，冷凝液为水，使用前可将塑料管8放在冰箱内冷冻。本实施例中，由于冷冻后水结成冰，被吸进管道的热油烟经过层层碎冰块时，温度迅速降低成液态，和水蒸气冷凝成的水混在一起排入排污系统或粘在碎冰块的外包装上，只有少量废气通过过滤装置过滤，因此油烟在经过过滤装置后基本上被消除，由此不仅管道内基本上没有油污，管道以外的机腔由于没有油污进入也基本保持干净。
例如，本申请的冷凝装置还可具有多种不同的实现方式。图3为根据本公开实施例的另一种冷凝装置的结构示意图。图3的冷凝装置包括多个相互连通的容器300，每个容器300中填充有冷凝剂。本文中“相互连通”指的是在多个容器之间形成连接通道，并且冷凝剂可以利用这些连接通道在多个容器之间流动。例如，冷凝装置包括相互连通的七个容器300，这七个容器300之一位于中心位置(称为中心容器)，其余六个围绕在中心容器的四周，并且位于周围的每个容器与中心容器之间设有连接通道303，由此相互连通。例如，容器之间彼此连接以形成为模块化的整体结构，这样便于从吸油烟机中取出。可以理解的是，图3中容器的数量仅为示意性目的，容器的数量可以为任意个数，例如可以是一个、两个、三个、八个、十个等，具体数量根据实际需要而定，本公开实施例对此不作限定。例如，图3的容器300为瓶装，可以理解的是，该容器还可以具有其他形状，例如袋状或管状等，只要可以容纳冷凝剂的容器，都可以包括到本公开实施例中。容器300的制作材料可以是市售一次性水杯的制作材料或类似材料，价格十分低廉。例如，冷凝剂为水，这样可降低用料成本，且便于随时取用。进一步地，至少一个示例中，冷凝装置还包括共同的注液口301。例如，冷凝装置还包括盖子302，盖子302覆盖注液口301，多容器模块化，这样可以增加热油烟或热水汽与冷凝剂的接触面积，提高冷凝效果。在使用冷凝装置之前，可自行注水至容器内，封闭后冷冻备用。每次用后将容器放在掺有洗涤液的水中轻刷，冲洗干净可反复使用。因此，本公开实施例的冷凝装置既可以反复使用，也可以是一次性用 品。具体应用时，可根据不同应用场景做出选择。
例如，吸滤排管道系统还包括设置在进风管24中的过滤装置和位于冷凝装置和过滤装置之间的第二网格状隔板22，过滤装置用于过滤从冷凝装置中排出的、且经过第二网格状隔板22的油烟。
例如，过滤装置包括过滤杯9，过滤杯9中设置有过滤剂10。例如，过滤杯9的形状如冷凝杯7。为了便于过滤杯9的安装固定，具有靠近所述冷凝杯一侧的的底部，该底部具有网格状，这样有利于油烟从该底部进入过滤杯9中。例如，过滤杯9放置在第二网格状隔板22上，由第二网格状隔板22支撑。该第二网格状隔板22的材料、结构可采用与第一网格状隔板21相同或不同，本公开对此不作限制。进一步地，当二者采用相同材料和结构时，有利于降低制造工艺的难度。至少一个示例中，过滤杯9中盛有疏松多孔且吸附油烟能力强的过滤剂10，这样可增强油烟过滤效果。冷凝主要针对热油烟，水蒸汽，而过滤则主要针对燃烧所产生的废烟气，本实施例的吸油烟机采用冷凝和过濾相结合的方式，实现了油烟分离且逐个去除的效果。
例如，吸滤排管道系统还包括开设在进风管24上的第一门11，第一门11的位置对应过滤装置和冷凝装置中的至少一个，以使对应以使过滤装置和冷凝装置中的该至少一个通过第一门11从进风管24中取出或放入。如图1所示，第一门11的位置同时对应过滤装置和冷凝装置二者，这样便于同时更换过滤装置和冷凝装置。至少一个示例中，第一门11可从外面开启，并且在打开进风管24的打开位置和封闭进风管24的关闭位置之间转动，这样便于操作者的维修、更换或清洗。可以理解的是，第一门11的具体结构不限于图1所示的结构，能够实现上述开启和封闭进风管24的其他结构的开合结构也包括在本公开范围内。
例如，吸滤排管道系统还包括抽风机5和排气管6，排气管6与抽风机5连接，抽风机5抽出经过滤装置过滤的油烟并且通过排气管6排出。如图1所示，抽风机5和排气管6安装在进风管24的上部，与冷凝装置、过滤装置一起组成了全封闭的吸滤排管道系统。
例如，吸滤排管道系统还包括开设在进风管24上的第二门12，第二门12所在的位置对应抽风机5，以使抽风机5通过第二门12从进风管24中取出或放入。第二门的设置便于清洗抽风机5。该第二门12的设置方式可参见第一门11的设置方式，此处不再赘述。
上述至少一个实施例的吸油烟机的工作原理是：通过配备的高速气流发生装置，沿着锅外围适当距离产生一圈圆筒状的薄薄的高速气流幕18，自上而下，直抵灶台挡板为盖，一起组成一个“罩子”，将油烟废气全部罩住，不使扩散，然后通过位于机子中心部位的全 封闭吸滤排管道系统吸入并过滤排出。简而言之，即“先罩住再吸排”，实现厨房油烟废气全程可控。
值得说明的是，本公开实施例的吸油烟机除高速气流发生装置、吸滤排管道系统之外，还包括电控制系统。另外，本公开实施例的吸油烟机，其功能和控制系统是单机对应单灶的，但在做成产品时也可将对应双眼灶的两个吸油烟机整合在同一外壳内。
综上所述，传统吸油烟机由于无法完全控制油烟废气，只能采用大功率，大吸力，大面积吸排的方式。进风口是敞开的，面积很大，所以机子也做得很大，然而吸排的大部分是未污染的空气，因此功效低、噪音大。与之相比，本申请上述实施例至少具有如下优点：
1)由于高速气流本身是空气，清洁而透明，具有可穿越性，不会对烹饪操作造成妨碍。油烟废气被高速气流幕和挡板完全罩住，居室内废气净化率大幅提升，空气质量可达到令人满意的程度。
2)大幅减少了吸油烟机的工作范围和工作量，简化了结构、降低了能耗。吸油烟机的尺寸比日用炒锅稍大即可，小巧玲珑，不仅节约了生产成本，同时还节约了用户宝贵的厨房空间。
3)因滤油网，挡油板、废气箱等都不再需要，吸油烟机的体积缩小三分之二以上，节约生产成本，节约用户安装空间，精简吸油烟机的结构，功效大幅提升，能效大幅减少，噪音相应降低，清洁变得很容易。
4)油烟废气罩住后全部吸入吸滤排管道系统集中排放，十分有利于废气的净化处理，机内油污情况得到改善，为实现厨房有害气体室外零排放创造了条件，保护了广大消费者的身体健康。
本文中，有以下几点需要说明：
(1)本公开实施例附图只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)为了清晰起见，在用于描述本公开的实施例的附图中，层或区域的厚度被放大或缩小，即这些附图并非按照实际的比例绘制。
(3)在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
