本申请提出一种吸油烟机。
参照图1和图2,在本申请一实施例中,该吸油烟机包括烟机主体1、和设在烟机主体1外的空气净化装置2。其中:
烟机主体1设有吸油烟风道,该吸油烟风道的进烟口连通室内,并通常悬置在厨房的灶具上方,以便于将油烟吸入吸油烟风道中;该吸油烟风道的排烟口连通室外,以将油烟排出到室外;当然,烟机主体1还设有油烟风机,用以使气流自进烟口流向排烟口。可以理解,烟机主体1具备相关技术中的吸油烟机的功能。
空气净化装置2包括设在烟机主体1外的净化外壳21、及设在净化外壳21内的过滤件22和净化风机23,净化外壳21设有进风口21a和出风口21b,过滤件22和净化风机23均设于进风口21a与出风口21b之间。可以理解,净化外壳21内形成有净化风道,该净化风道与吸油烟风道相互独立。净化风机23用以使气流自所述进风口21a流向所述出风口21b。所述进风口21a和所述出风口21b均连通室内,所述进风口21a用以吸入厨房室内的空气,过滤件22用以对吸入的空气进行过滤净化,所述出风口21b用以将过滤净化后的空气排回厨房室内。在空气净化装置2与烟机主体1协同工作时,烹饪过程所产生的油烟大部分通过烟机主体1内的吸油烟风道排出至室外,小部分油烟会逃逸至厨房内其他空间,这小部分油烟可通过空气净化装置2内的净化风道得到进一步的去除,从而进一步减少油烟对空气环境的污染和对人体健康的损害。
进一步地将净化外壳21可拆卸连接于烟机主体1,从而使得空气净化装置2整体与烟机主体1可拆卸连接,如此设置可以方便空气净化装置2与烟机主体1的装配,实现模块化的装配,并且方便在运输过程中将二者进行单独运输。并且,当烟机主体1和空气净化装置2的其中之一损坏时,也可以进行单独的拆卸和维修,降低维护成本。
参照图1和图2,在一实施例中,烟机主体1包括风机罩11和设于风机罩11下方的集烟罩12,净化外壳21设于集烟罩12上方,净化外壳可拆卸连接于所述集烟罩。
本实施例中,烟机主体1的吸油烟风道的进烟口设置在集烟罩12下方。集烟罩12下方的油烟主要由所述进烟口吸入,也即主要由吸油烟风道排出至室外。自集烟罩12边沿向上逃逸的油烟则主要由净化外壳21的进风口21a吸入处理。
通过将净化外壳21可拆卸连接于集烟罩12,从而使得集烟罩12为主要的承重部件,因集烟罩12位于风机罩11的下方,因此可以方便空气净化装置2的整体的装配。
在将净化外壳21可拆卸连接于集烟罩12时,其采用的方式可以为多种,例如采用螺钉锁附结构、卡扣结构等可拆卸结构中的一种或多种来安装在烟机主体1,以便于空气净化装置2的维修拆装。
结合参照图2至图6,在本申请的一实施例中,通过在集烟罩12和净化外壳21的其中之一设有插接槽121,集烟罩12和净化外壳21的其中之另一设有插接脚211,插接脚211可拆卸插接于插接槽121内,以此来完成净化外壳21的安装。插接脚211和插接槽121的设置,结构较为简单。其形成可以为环形的插接槽121和环形的插接脚211。也可以为柱状的插接脚211和对应设置的插接槽121,其数量可以为多个,呈间隔均匀排布,从而使得安装更加稳定。也可以为一个,从而简化对插结构。插接脚211可以设置在净化外壳21的底部,也可以设置在侧边,主要看净化外壳21与集烟罩12的相互连接的安装位置而定。
进一步地,还可以设置磁性吸附的方式进一步使得二者的连接更加稳固。例如在一实施例中,集烟罩12和净化外壳21的其中之一设有第一磁性件212,集烟罩12和净化外壳21的其中之另一设有第二磁性件122,第一磁性件212与第二磁性件磁性吸附。通过第一磁性件212和第二磁性件122的磁性吸附,使得集烟罩12和净化外壳21的相互连接和安装更加稳定。当然,第一磁性件212和第二磁性件122的形状和位置可根据需要设置。例如第一磁性件212可以设置在净化外壳21的底部,第二磁性件122设置在集烟罩12的上表面,从而完成磁性对接安装。
当然,还可以将磁性吸附和插接固定的方式进行结合使用,在一实施例中,集烟罩12和净化外壳21的其中之一设有插接槽121,集烟罩12和净化外壳21的其中之另一设有插接脚211,插接脚211设有第一磁性件212,插接槽121内设有第二磁性件122,插接脚211可拆卸插接于插接槽121内时,第一磁性件212与第二磁性件122磁性吸附。也即,可以通过先对插,再磁吸,使得二者的连接更加稳固。
如上文的实施例介绍,在将净化外壳21设于集烟罩12时,可以将上述的各种连接结构设置在净化外壳21的底部,对应的,在安装时,可以将净化外壳21设于集烟罩12的上表面,从而使得二者能够稳固安装。
在设置集烟罩12上表面的具体方位时,结合参照图1和图5,一实施例中可以将净化外壳21设置在风机罩11的正面。通过将净化外壳21设置在风机罩11的正面,使得其离用户的距离较近,可以使得用户能够直接呼吸到新鲜空气。可以结合正面设置的出风口进行设置,出风效果好。
在一实施例中可以将净化外壳21位于风机罩11的侧面。烟机主体1的正下方一般为吸力最强的位置,将净化外壳21放置在侧面,可以有利于将逃逸至空气净化装置2上方的油烟吸入并净化。
在一实施例中可以将净化外壳21位于风机罩11的侧面和正面之间的边角处。将净化外壳21放在拐角处,该拐角处的位置比较大,放置空间更足,更方便净化外壳21的拆卸和装配。
空气净化装置2和烟机主体1均具有独立的风道和风机,在工作时,为了降低空气净化装置2和烟机主体1在工作中的相互震动影响,在一实施例中可以设置为:净化外壳21与集烟罩12之间设有减震垫(未图示)。集烟罩12为主要承载的部件,通过在净化外壳21和集烟罩12之间设置减震垫,可以降低二者工作时的相互干渉影响。将净化外壳21与风机罩11之间设有缓冲垫。净化外壳21和风机罩11之间还设置缓冲垫(未图示),可以进一步降低二者工作时的相互干渉影响。减震垫和缓冲垫可以为橡胶垫或硅胶垫等软性材质。在设置时减震垫和缓冲垫可以结合使用,也可以单独使用。
参照图1和图7,在一实施例中,所述出风口21b设于净化外壳21的正面;如此,在空气净化装置2开启后,空气净化装置2朝前出风或者至少具有朝前的出风分量。在烹饪过程中,用户通常站立在吸油烟机前方,可将吸油烟机前方的空间定义为用户呼吸区。可以理解,朝前出风有利于将净化后的空气输送至用户呼吸区,从而有利于改善用户呼吸区的空气质量,能进一步降低用户吸入油烟的概率,减少油烟对用户健康的损害。
然本设计不限于此,于其他实施例中,所述出风口21b也可设于净化外壳21的顶面,如此,在空气净化装置2开启后,空气净化装置2朝上出风或者至少具有朝上的出风分量。可以理解,由于烹饪过程中热羽流的作用,油烟往往在厨房空间的上半部分聚集,朝上出风有利于将净化后的空气吹向厨房空间的上半部分,以通过净化空气以使得厨房空间上半部分的油烟在向上吹的净化空气的推动下,向下流动,至被空气净化装置2的进风口21a吸入并净化,从而实现厨房内的空气循环净化,能进一步减少厨房内的油烟。
在一实施例中,所述出风口21b的出风方向可调,如此,对于设于净化外壳21正面的出风口21b,可通过改变其出风方向,来满足用户对空气净化装置2的更多出风需求,例如,满足不同身高用户的直吹或不直吹需求等。
参照图2至图4,在一实施例中,所述出风口21b设有出风格栅25,以避免异物自所述出风口21b伸入净化外壳21内。在一实施例中,所述出风格栅25包括可转动设置的导风栅条251,以通过转动导风栅条251来调整所述出风口21b的出风方向,且所述出风口21b的出风方向连续可调。然本设计不限于此,于其他实施例中,可配置多个固设有导风栅条251的出风格栅25,且不同出风格栅25的导风栅条251与竖直面之间的倾角不同,根据出风方向的需要,选择具有对应倾角导风栅条251的出风格栅25安装在所述出风口21b上,如此,更换不同的出风格栅25,能改变所述出风口21b的出风方向;另外,在一实施例中,所述出风格栅25还包括格栅框,导风栅条251连接于格栅框,格栅框通常可拆卸连接于所述出风口21b,并可但不限于采用螺钉锁附结构、卡扣结构等可拆卸结构中的一种或多种来安装在所述出风口21b。
对于设于净化外壳21正面的出风口21b,在一实施例中,所述出风口21b的出风方向与竖直面之间形成有开口靠下的第一可调倾角,所述第一可调倾角不小于30°,不超过150°,如此,所述出风口21b的出风方向具有较大的调整范围,能够满足更多工况的需求。需要说明的是,当所述可调倾角小于90°时,所述出风口21b倾斜朝下出风,有利于改善用户呼吸区的空气质量。而当所述可调倾角大于90°时,所述出风口21b倾斜朝上出风,如此,所述出风口21b会具有朝上的出风分量,该朝上的出风分量能将厨房空间上半部分的油烟推动着向下流动,至被空气净化装置2的进风口21a吸入并净化,从而将厨房空间上半部分的油烟纳入到空气循环净化中来,能进一步减少厨房内的油烟。
对于设于净化外壳21正面的出风口21b,在另一实施例中,所述出风口21b的出风方向与水平面之间形成有开口靠上的第二可调倾角,所述第二可调倾角不小于30°,不超过75°,如此,所述出风口21b的出风方向倾斜朝上,从而可将吸油烟机斜上方的油烟推动下来,也即,能在吸油烟机前方的整个空间内形成一个大范围的空气净化循环,能更为有效地减少厨房内的油烟量。
在一实施例中,所述进风口21a设于净化外壳21的顶面;如此,有利于将逃逸至空气净化装置2上方的油烟吸入并净化。可以理解,由于烹饪过程中热羽流的作用,油烟趋于向上逃逸,而使得空气净化装置2上方聚集有较多的油烟,在净化外壳21的顶面设置所述进风口21a,可便于吸入这些油烟。
然本设计不限于此,于其他实施例中,参照图1和图2,所述进风口21a设于净化外壳21的侧面,如此,有利于将逃逸至吸油烟机侧方的油烟吸入净化外壳21内,以减少吸油烟机侧方的油烟。特别地,当吸油烟机下方所使用的是双炉头的灶具时,烹饪时所产生的油烟易于从吸油烟机的侧方向上逃逸,将位于净化外壳21侧面的进风口21a更有利于吸入这些油烟。在一实施例中,净化外壳21的相对两侧面均设有所述进风口21a,以减少吸油烟机两侧的油烟。当然,也可仅在净化外壳21两个侧面中的一个设置所述进风口21a。在一实施例中,所述进风口21a上设有进风格栅24,以避免手和其他异物伸入净化外壳21内。
当然,于其他再一些实施例中,还可在净化外壳21的顶面和侧面均设置所述进风口21a,如此,可同时减少空气净化装置2上方和吸油烟机侧方的油烟。
另外,对于净化外壳21的相对两侧面均设有所述进风口21a的技术方案,参照图1和图2,在一实施例中,过滤件22设有两个,每一所述过滤件22靠近一所述进风口21a设置;如此,可使得带有油烟的空气一进入净化外壳21,就能得到过滤件22的过滤,减少带有油烟的空气污染净化外壳21内其他器件的概率。然本设计不限于此,于其他实施例中,也可仅设有一个靠近所述出风口21b设置的过滤件22,如此,亦能实现将空气中的油烟净化后再排出。
在将烟机主体1和空气净化装置2连接时,可以将二者的内部电路连通,从而完成烟机主体1和空气净化装置2的控制导通和/或信号导通。
在一实施例中,烟机主体1设有第一电触点,空气净化装置2设有第二电触点,空气净化装置2连接于烟机主体1时,第一电触点与第二电触点电性连接。第一电触点和第二电触点可以为相互配合的电极,其设置形成可以为插针连通,也可以为贴片连通。
在将二者电路导通后,在一实施例中,烟机主体1和空气净化装置2连接于同一个控制器3,也即,该吸油烟机通过同一个控制器3控制烟机主体1和空气净化装置2;该控制器3通常设置在烟机主体1上,相较于空气净化装置2,烟机主体1通常体积更大,从而具备更多的可供控制器3安装的位置和空间。然本设计不限于此,于其他实施例中,该吸油烟机也可设置两个不同的控制器3,以分别控制烟机主体1和空气净化装置2。
在一实施例中,烟机主体1和空气净化装置2共用一个控制开关4,如此,通过控制开关4打开烟机主体1进行工作时,会同时自动打开空气净化装置2进行工作,也即,能实现一键开启烟机主体1和空气净化装置2的协同工作。控制开关4通常电连接至控制器3,以实现开、停机的控制。共用一个控制开关4时,控制开关4通常设置在烟机主体1上。
然本设计不限于此,于其他实施例中,烟机主体1和空气净化装置2也可分别使用不同的控制开关4,以实现烟机主体1和空气净化装置2各自独立的开、停机控制,使得用户可更为灵活地使用烟机主体1和空气净化装置2各自的功能。分别使用不同的控制开关4时,该两个控制开关4可以都设置在烟机主体1上;当然,该两个控制开关4也可以分别对应设置在烟机主体1和空气净化装置2上。
通常地,烟机主体1设有位于集烟罩12正面的控制面板,在烟机主体1和空气净化装置2共用一个控制开关4时,该控制开关4通常集成在控制面板上,也即,该控制开关4位于集烟罩12的正面,该位置可更为便于用户进行操作。
继续参照图1,在一实施例中,净化外壳21设于风机罩11正面的下部;可以理解,风机罩11正面的下部更为靠近用户呼吸区,也即,净化外壳21的出风口21b更为靠近用户呼吸区,更有利于将净化后的空气吹向用户呼吸区,以改善用户呼吸区的空气质量。然本设计不限于此,于其他一些实施例中,净化外壳21还可设于风机罩11正面的上部,如此,净化外壳21的位置较高,则所述出风口21b的位置也较高,特别地,在所述出风口21b的出风方向倾斜朝上时,可使得自所述出风口21b吹出的净化空气能吹送到厨房内更高的空间,从而使得厨房内空气循环净化的范围更大,净化更彻底。而于其他再一些实施例中,净化外壳21还可设于风机罩11正面的中部,如此,能兼顾改善用户呼吸区的空气质量,及一定程度地增大厨房内空气循环净化的范围。
在一实施例中,净化风机23配置为离心风机(见图2),一方面离心风机风量较大,且噪音较小,可使得空气净化装置2能在低噪音下,实现较远的送风;另一方面离心风机具有改变风向的作用(轴向进风,径向出风),能在不专门设置转弯的风道部件的前提下,实现空气净化装置2的顶面进风正面出风、或者两侧进风正面出风。
在一实施例中,净化风机23的循环风量不小于10立方米/时;可以理解,若循环风量过小,则不利于厨房内空气循环净化的实现。需要说明的是,本技术方案中的循环风量是指单位时间内的风量。在本实施例中,通常地,所在厨房的面积越大,净化风机23的循环风量需要越大,可根据厨房面积的需要,选取循环风量为50立方米/时、100立方米/时、150立方米/时、200立方米/时、250立方米/时或300立方米/时的净化风机23。当然,对于同样的厨房,净化风机23的循环风量越大,越有利于厨房内的空气循环净化。
在烹饪过程中,食用油和食物在高温下发生一系列氧化、裂解、聚合等化学反应,蒸发出大量的有机烟气,其中部分分解物以油雾形式发散到空气中形成油烟气。所说的油烟既包括食用油及其加热分解或裂解的产物,又包括食物中的蛋白质、高分子化合物和各种佐料发生物理化学反应的产物,是一种包含有气体、液体和固体三种状态的物质。通常这样定义,把油烟排放中由液体和固体组成的颗粒物排放(Particulate Matter Emissions)简称PME,把挥发性有机化合物排放(Volatile Organic Compounds Emissions),简称为VOCs,油烟就是由以上两类物质组成。
参照图2,在一实施例中,过滤件22包括HEPA过滤网221(高效空气过滤网)和活性炭过滤网222。其中,HEPA过滤网221主要用于对油烟中的颗粒物(液体和固体)进行过滤,其材质可以包括PP滤纸(聚丙烯滤纸)、玻璃纤维、PTFE滤纸(聚四氟乙烯滤纸)、纳米纤维、熔喷涤纶无纺布等,具有容尘量大,过滤精度高的特点,对油烟颗粒物的过滤效率可超过90%,并可根据机型需要加工成所需的尺寸和形状。活性炭过滤网222则主要用于对油烟中的挥发性有机化合物(气味)进行过滤,其材质可以包括活性炭纤维、活性炭颗粒等,且所采用的活性炭材料可选用椰壳、果壳以及煤质碳等,这类材料比表面积较大,又或者,所采用的活性炭材料可选用分子筛材料,这类材料吸附效果较好。在一实施例中,在气流方向上,HEPA过滤网221位于活性炭过滤网222上游,如此,可避免油烟中的颗粒物附着在活性炭过滤网222上,从而延长活性炭过滤网222的使用寿命。
在一实施例中,在气流方向上,过滤件22位于净化风机23上游;如此,可使得经过净化风机23的气流为净化后的气流,避免油烟在所述净化风机23上积聚,延长净化风机23寿命。
参照图1和图2,在一实施例中,净化外壳21设有滤件安装口210,过滤件22通过该滤件安装口210可拆卸安装至净化外壳21内,如此,可便于过滤件22的拆出清洗或更换。可以理解,过滤件22通常具有一定的寿命,例如,本技术方案中所采用的HEPA过滤网221,其设计使用寿命通常在1个月以上,在其使用寿命到达后需要将其更换,以保证空气净化装置2的净化能力良好,另外,将其定期或者不定期地拆出进行清理或清洗,有利于延长其使用寿命。
对于同时包括HEPA过滤网221和活性炭过滤网222的过滤件22,在一实施例中,其HEPA过滤网221和活性炭过滤网222通常被生产成一个模块,以便于模块化地将其一次性装配至净化外壳21,减少装配工序,提高装配效率。
在一实施例中,过滤件22可抽拉地设于所述滤件安装口210;可以理解,通过抽拉的方式,能更为方便地进行过滤件22的拆出清洗或更换。
在一实施例中,净化外壳21内设有朝向滤件安装口210延伸的安装槽220,过滤件22安装于所述安装槽220中;可以理解,所述安装槽220朝向所述滤件安装口210延伸,以具有导向安装的作用,能便于过滤件22相对滤件安装口210的可抽拉实现。
对于所述进风口21a设于净化外壳21侧面的技术方案,在一实施例中,参照图2,空气净化装置2还包括设在净化外壳21内的滤件安装盒28,该滤件安装盒28对应滤件安装口210设有安装过口220a,所述安装槽220设于所述滤件安装盒28内,过滤件22依次穿过所述滤件安装口210和所述安装过口220a而装入所述安装槽220中。当然,滤件安装盒28的与过滤件22相对的盒侧壁呈镂空设置或者空置,以使得气流能流经过滤件22。在一实施例中,滤件安装盒28的底壁和顶壁均凸设有朝向安装过口220a延伸的并行两导轨281,所述安装槽220形成在该两导轨281之间。
在一实施例中,所述滤件安装口210上设有滤件盖26;如此,在将过滤件22自所述滤件安装口210装入净化外壳21后,将滤件盖26盖合滤件安装口210,能避免过滤件22晃出,提高产品的结构稳定性,同时还能避免异物等从滤件安装口210进入净化外壳21内。
在一实施例中,滤件盖26的第一侧可转动连接于所述滤件安装口210,第二侧可拆卸连接于所述滤件安装口210;如此,在打开滤件盖26之后,滤件盖26仍然连接于滤件安装口210,可避免滤件盖26丢失。然本设计不限于此,于其他实施例中,滤件盖26也可整体地可拆卸连接于所述滤件安装口210。
对于滤件盖26第一侧可转动连接于所述滤件安装口210的技术方案,在一实施例中,滤件盖26的第二侧通过按压式卡扣开关组件连接于所述滤件安装口210,如此,可便于滤件盖26的打开。所述按压式卡扣开关组件通常包括设于所述滤件安装口210的自锁开关、及设于所述滤件盖26并与所述自锁开关配合的卡扣部。在滤件盖26处于打开状态下,将滤件盖26转动至第二侧靠近所述滤件安装口210的位置,然后按压滤件盖26,至所述卡扣部进入所述自锁开关,使所述自锁开关锁定所述卡扣部,即可使所述滤件盖26与所述净化外壳21固定;之后,再次按压所述滤件盖26时,所述自锁开关会松开所述卡扣部,从而使所述滤件盖26可相对所述滤件安装口210转动打开。然本设计不限于此,于其他实施例中,滤件盖26的第二侧还可但不限于通过螺钉锁附结构、扳扣结构等与所述滤件安装口210可拆卸连接。
以上所述仅为本申请的优选实施例,并非因此限制本申请的专利范围,凡是在本申请的发明构思下,利用本申请说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
