在很多送风应用场合，通常需要根据实际情况提供不同的风量。例如，冰箱内储存食品的空间较大且分隔为不同区域，需要对不同位置输送所需风量的冷风以进行相应的冷却保藏。现有技术中，通常通过设置风门等装置来调节输送量。风门通常为枢转地安装在风道内的挡板，以通过枢转来控制风道的连通与否，因而只能控制是否送风，无法针对实际不同的风量需求来调节送风量。

为了实现上述目的，本发明一方面提供一种控风装置，其中，所述控风装置包括控制部和开孔板，开孔板所述开孔板设置有风口，所述控制部能够相对于所述开孔板转动，以在所述控制部转动到不同位置时使所述风口开启、部分开启或关闭。
本发明还提供一种冰箱，其中，所述冰箱包括本发明的控风装置。
通过上述技术方案，通过控制部的转动，可以使风口开启、部分开启或关闭，从而控制通过风口的风量来根据需要提供所需的风量。

具体实施方式
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、左、右”通常是指参考附图所示的上、下、左、右；“内、外”是指相对于各部件本身的轮廓的内、外。
根据本发明的一个方面，提供一种控风装置，其中，所述控风装置30包括控制部32和开孔板33，所述开孔板33设置有风口331，所述控制部32能够相对于所述开孔板33转动，以在所述控制部32转动到不同位置时使所述风口331开启、部分开启或关闭。
通过控制部32的转动，可以使风口331开启、部分开启或关闭，从而控制通过风口的风量来根据需要提供所需的风量。
具体的，一方面，可以通过风口331的开启(包括部分开启)或关闭来实现开孔板331两侧的气流通路的连通与否；另一方面，可以通过风口331的部分开启程度控制通过风口331的风量。
优选地，开孔板33可以设置有多个风口331，并通过控制部32的转动，使不同的风口331处于不同状态。具体的，可以使不同位置、数量的风口331开启或部分开启，从而通过开启或部分开启的风口331送风或进风。
另外，如图3和图6所示，气流从控风装置30的一侧(垂直于控风装置30的转动轴线(图3和图6中上下方向)的方向的一侧(图3和图6中右侧))进入并从另一侧(图3和图6中左侧)送出，能够在控风装置30的一侧大量进风，有利于提高进风效率和送风效率并能够减少气流因控风装置30转动导致的损耗。
优选地，至少两个所述风口331不同时开启，以便根据功能需要与其他风口331的不同状态进行组合来设置各种工作模式。
为通过控风装置30实现多种工作模式，优选地，每个所述风口331可以设置为具有单独开启的状态，以便具有分别通过各个风口331送风或进风的单区域工作模式。另外，至少一个所述风口331为多状态风口，所述多状态风口能够与其他的所述风口331同时开启(包括部分开启)，以便具有至少两个风口331进行送风或进风的多区域工作模式。
此外，所述控风装置可以设置为具有使得多个所述风口331全部关闭的状态。
其中，通过合理组合不同风口331的单独开启状态、与其他风口同时开启的状态等，可以实现各种所需的送风或进风状态。例如，以风口331的开启(这里指开启至最大流量)和关闭为例，每个风口331具有开启和关闭两个状态，如控风装置30设置有m个风口331，则根据排列组合，可以具有2m个工作模式，包括：风口331全开启、风口331全关闭、第一个风口331(按排列方向排序)开启而其他风口331全关闭、第一个和第二个风口331开启而其他风口331全关闭……第一个风口331关闭而其他风口331全开启。根据控制风口331的风量需要，还可以设置风口331部分开启所对应的更多的工作模式。
本发明中，控制部32可以设置为适当的结构，以通过转动来实现风口331的开启、部分开启和关闭。
根据本发明的一种实施方式，如图1a至图3所示，所述控制部32包括筒状件32a，所述筒状件32a的侧壁上设置有多个开口321，多个所述开口321能够通过所述控制部32的转动而分别与所述风口331对准。
其中，“对准”表示开口321在风口331的端面上具有彼此重合的区域， 包括完全重合和部分重合。完全重合则使风口331开启，部分重复则使风口331部分开启。
通过筒状件32a的转动，可以使风口331与开口321对准，继而通过筒状件32a的中空结构与其他的开口321连通，从而通过风口331和筒状件32a外部的连通实现开孔板33两侧的气流通路连通。换言之，通过筒状件32a的转动，可以通过风口331以及开口321形成经筒状件32a内部、连通筒状件32a外部和风口331的气流通路来实现送风。
具体的，一方面，可以通过使筒状件32a转动到使得开口321与风口331对准或不对准来控制风口331开启与否；另一方面，可以通过使筒状件32a转动到使得开口321与风口331不同程度地部分重合，从而控制通过风口331的风量。
优选地，所述开孔板33为长条板并包括沿所述长条板的长度方向排列的多个所述风口331，所述筒状件32a的转动轴线平行于多个所述风口331的排列方向，所述筒状件32a包括沿所述筒状件32a的转动轴线方向设置的多组所述开口321，每组所述开口321能够通过所述筒状件32a的转动而分别与同一个所述风口331对准。由此，通过筒状件32a的转动，可以使不同风口331与相应的开口321对准。
其中，当风口331作为出风口时，可以通过与开口321对准的风口331送风并通过其他开口321进风，例如可以通过风口331对冰箱的不同位置进行送风。当风口331作为进风口时，可以通过与开口321对准的风口331进风并通过其他开口321出风到所需位置(例如冰箱的回风口)。
在图2和图3所示的实施方式中，风口331为出风口，筒状件32a外部的气体可以从各个方向经开口321进入筒状件32a内，然后经与风口331对准的开口321送出该风口331。同理，风口331作为进风口的操作过程与上述类似，在此不作详述。
本发明中，筒状件32a可以为圆筒形或其他横截面的中空筒状结构。优选地，为便于布置，在图示的实施方式中，筒状件32a的转动轴线可以为筒状件32a自身的轴线，从而每组开口321沿筒状件32a的同一周向间隔设置。另外，不同组的开口321可以沿转动轴线的方向对齐、错开或部分对齐，以实现不同工作模式。
优选地，如图1b所示，至少两组所述开口321中具有沿轴向错开的所述开口321。由此，在筒状件32a的转动过程中，该至少两组开口321对应的两个风口331具有不同时开启的状态(当风口331为出风口时，则具有不同时送风的状态；当风口331为进风口时，则具有不同时进风的状态)，以便根据功能需要与其他风口331的不同状态进行组合来设置各种工作模 式。
此外，为减少气体在流动时的损失并且便于设置控风装置30的送风方向，优选地，所述控风装置30包括沿所述筒状件32a的径向相对地成对设置的开口321，每对所述开口321沿所述筒状件32a的径向相对，可以确保其中一个开口321与风口331对准时，从另一个开口321进入的冷风能够对流地送出。其中，成对的开口321不一定属于同组的开口321。
此外，为集中进气向外输送，优选地，所述筒状件32a的内部轴向连通，从而在多个风口331中的一部分风口331送风时，能够集中进入筒状件32a内的所有冷气向外输送。
根据本发明的另一种实施方式，如图4至图6所示，所述控制部32包括转轴32b，所述转轴32b设置有径向突出的挡块B，以在所述转轴32b转动的过程中通过所述挡块B遮挡所述风口331。
其中，“遮挡”表示挡块B在风口331的端面上具有彼此重合的区域，包括通过挡块B完全遮挡风口331(风口331关闭)和部分遮挡风口331(风口331部分开启)。
通过使转轴32b带动挡块B转动，可以使挡块B遮挡风口331，从而阻断开孔板33两侧的气流通路。换言之，通过转轴32b的转动，可以在挡块B未遮挡风口331时，通过风口331实现开孔板33两侧的气流通路连通并实现送风。
一方面，可以通过使转轴32b转动到使得挡块B遮挡风口331或不遮挡风口331来控制开孔板33两侧的气流通路的连通与否；另一方面，可以通过使转轴32b转动到使得挡块B不同程度地部分遮挡风口331，从而控制通过风口331的风量。
优选地，所述开孔板33为长条板并包括沿所述长条板的长度方向排列的多个所述风口331，所述转轴32b的轴向平行于多个所述风口331的排列方向，所述转轴32b设置有沿轴向排列的多个所述挡块B。由此，通过使转轴32b带动挡块B转动，可以使不同的挡块B遮挡不同的风口331，被遮挡的风口331关闭，未被遮挡的风口331开启(包括部分开启)，各个方向的风可以通过不同的未被遮挡的风口331送风。
优选地，如图4所示，多个所述挡块B沿所述转轴32b的轴向设置为多组，每组所述挡块B对应于同一个所述风口331，至少两组所述挡块B中具有沿轴向错开的所述挡块B。由此，在转轴32b的转动过程中，该至少两组挡块B对应的两个风口331具有不同时被遮挡的状态，以便根据功能需要与其他风口331的不同状态进行组合来设置各种工作模式。可以理解的，每组挡块B包括至少一个挡块B，既可以包括一个挡块B，也可以 包括多个挡块B。
其中，为便于通过转轴32b转动到不同位置来实现不同工作模式，优选地，每组所述挡块B包括沿所述转轴32b的同一轴向位置周向间隔设置的多个所述挡块B。其中，不同组的挡块B可以沿轴向对齐、错开或部分对齐。由此，可以通过每组的多个挡块B在转轴32b转动到不同位置时分别遮挡对应的风口331，使得该风口331在多个不同状态下关闭，以便根据功能需要与其他风口331的不同状态进行组合来设置各种工作模式。
本发明中，为实现控制部32的转动，所述控风装置30可以包括转动支架34，所述开孔板33固定于所述转动支架34，所述控制部32可转动地安装于所述转动支架34。
本发明中，可以通过各种适当的方式驱动控制部32，例如手动转动控制部32。为便于自动控制，所述控风装置30可以包括用于驱动所述控制部32转动的电机35，电机35外侧还可以通过保护罩351保护。优选地，所述电机35为双向电机，以便在360°范围内更精确地驱动控制部32转动到所需的工作模式。
其中，为精确确定控制部32的转动位置，所述控制部32和所述开孔板33可以通过彼此配合的止挡结构限定相对的参照位置。例如，可以通过止挡结构限定控制部32转动范围的起始或终点位置(当然也可以是其他参考位置，例如从相对转动的起始位置开始转动30°的位置)。其中，止挡结构可以为各种适当形式，并可以设置在适当的部件上。例如，止挡结构可以分别设置在所述控制部32和所述转动支架34上。具体的，控制部32上可以设置有第一校正块，转动支架34上可以设置有在所需定位的起始或终点位置与第一校正块止挡配合的第二校正块。
其中，为进一步精确控制控制部32转动到各工作模式对应的位置，所述控风装置30设置为能够具有n种不同的工作状态，所述电机35为步进电机并设置为以360°/n为间隔角度转动。下面结合图1至图14说明不同工作模式下的出风状态(在图1至图14的实施方式中，以开口231作为进风口，风口331作为出风口)。在图1a至图6所示的实施方式中，风口331包括依次设置的第一出风口331a、第二出风口331b和第三出风口331c，分别对应轴向区域一、轴向区域二和轴向区域三的送风，控风装置30设置为能够分别通过第一出风口331a、第二出风口331b和第三出风口331c实现单独送风工作模式、能够通过任意两个风口331实现联合送风工作模式、能够实现三个风口331同时送风的全送风工作模式并且能够实现将三个风口331全部关闭的关闭模式。控风装置30因此需要具有8个工作模式(这里，仅说明风口331关闭或完全开启的工作模式)，则可以将电机35设置 为以45°为角度间隔转动。为此，每个风口331在4个工作模式下关闭，在另外4个工作模式下开启。对于筒状件32a的实施方式而言，筒状件32a上设置有对应每个风口331的至少4个开口321，通过沿轴向错开和对齐不同开口321，可以实现上述8个工作模式；对于转轴32b的实施方式而言，转轴32b上设置有对应每个风口331的4个挡块B，通过沿轴向错开和对齐不同风口331的挡块B，可以实现上述8个工作模式。具体的工作模式的实现顺序可以根据需要选择。
例如，如图7所示，此时电机35出于起始位置，即转动0°，第一出风口331a、第二出风口331b和第三出风口331c均关闭；如图8所示，电机35转动到45°位置，第一出风口331a开启，第二出风口331b和第三出风口331c关闭；如图9所示，电机35转动到90°位置，第一出风口331a和第三出风口331c关闭，第二出风口331b开启；如图10所示，电机35转动到135°位置，第一出风口331a和第二出风口331b关闭，第三出风口331c开启；如图11所示，电机35转动到180°位置，第一出风口331a和第二出风口331b开启，第三出风口331c关闭；如图12所示，电机35转动到225°位置，第一出风口331a和第三出风口331c开启，第二出风口331b关闭；如图13所示，电机35转动到270°位置，第一出风口331a关闭，第二出风口331b和第三出风口331c开启；如图14所示，电机35转动到315°位置，第一出风口331a、第二出风口331b和第三出风口331c均开启。
另外，优选地，所述控风装置30包括密封接合在所述风口331和所述控制部32之间的密封件36，以确保通过风口331处的气密性。
根据本发明的另一方面，提供一种冰箱，其中，所述冰箱包括本发明的控风装置30。
根据本发明的一种实施方式，使用本发明的控风装置30对不同区域送风，具体的，控风装置30包括第一控风装置，所述冰箱包括风道100和多个储藏区域220，所述风道100包括风腔10，第一控风装置的开孔板33的设置有控制部32的一侧与所述风腔10连通，另一侧与所述储藏区域220连通。
由此，可以通过第一控风装置的风口331对储藏区域220送风。在具有多个储藏区域220的情况下，可以设置多个风口331分别与多个储藏区域220一一对应地连通，根据风口331的不同工作模式，可以使不同储藏区域220具有不同的工作状态组合。
根据本发明的另一种实施方式，所述风道100包括回风口80，控风装置30包括第二控风装置，第二控风装置的风口331与回风口80连通，以便通过风口331回风。在风口331与回风口80连通的情况下，可以控制经 回风口80的回风，特别是可以通过不同的数量和开启程度的风口331控制向回风口80送入的风量，从而控制回风量。
其中，控风装置30可以设置在适当位置，以便布置。例如，如图16-24所示，所述冰箱包括多个第一控风装置，多个所述第一控风装置设置在所述风腔10内的两侧位置，从而分别从两侧对冰箱的箱体200内的不同储藏区域220送风。具体的，如图15所示，箱体200的内部可以包括冷藏区和冷冻区，储藏区域220可以包括冷藏区通过搁架210分隔的多个隔间，第一控风装置从风腔10中部引入冷气并从箱体200的两侧送风(冷风流动路径如图17中箭头所示)，继而从冷藏区的两侧向隔间中部送风(冷风流动路径如图15中箭头所示)。其中，风腔10中引入冷风的位置(例如风机300的位置)通常位于风腔10的中部，通过将第一控风装置设置在风腔10内的两侧位置，可以尽量远离多系统冰箱中风机300的位置，以免影响风机300的效率并防止风机300的运转干涉第一控风装置的出风效率。另外，箱体200的下部还设置有冷冻区，储藏区域220还可以包括冷冻区的各个抽屉限定的储藏空间。冷藏区和冷冻区可以分别通过不同的风口331送风，以便实现冷藏区和冷冻区的单独和同时送风。
其中，可以在至少一部分风口331处设置传感器400，以监测该风口331的出风情况，并通过反馈到控制器，控制器可以根据需要适应性调整送风强度以达到该风口331对应的区域所需达到的制冷效果，并且向所需区域送风的风量可以通过开启或关闭其他风口331来调节。
风道100包括前盖板40、后盖板50和夹设在前盖板40与后盖板50之间的保温层60，风腔10通过后盖板50和保温层60限定。为便于安装，开孔板33可以设置在保温层60、前盖板40或后盖板50上。具体的，可以将开孔板33安装在保温层60、前盖板40或后盖板50上，例如，根据一种实施方式，如图18所示，保温层60上可以设置有控风装置安装部62(例如安装槽)，以安装控风装置30；可选择地，也可以将开孔板33一体形成在保温层60、前盖板40或后盖板50上(例如，所述开孔板33与所述后盖板50可以形成一体件，转动支架34也可以与后盖板50一体形成，如图24所示；或者，例如在保温层60上开设风口331而作为开孔板33，如图25所示)；还可选择地，也可以将开孔板33嵌入保温层60设置以减少连接构件。
此外，本发明的冰箱可以为多系统冰箱，例如图16至图20所示的实施方式，也可以为单系统冰箱，例如图21至图24所示的实施方式。
其中，对于多系统冰箱，风腔10内设置有风机300，以便从风腔10外抽取冷气并送至控风装置30。其中，为有利地将风机300抽取的冷气集 中导向，保温层60的风机腔内设置有蜗舌61。另外，如上所述，通过将控风装置30设置在风腔10两侧，可以使控风装置30远离风机300，避免控风装置30阻碍风机300抽吸的气流而产生损耗。
对于单系统冰箱，风腔10内不设置风机300，冷气从冰箱其他部分引入并送至控风装置30。
另外，还可以将所述控风装置30设置在所述风道100的回风口处，从而通过与回风口连通的风口331的开闭、开启程度和数量控制回风风量。
在此，结合附图说明冰箱的送风的工作过程。以图16至图20所示的多系统冰箱为例，如图20所示，风道100还包括位于风腔10下方的制冷装置70，回风口80位于制冷装置70下方，从回风口80进入的风流经制冷装置70而冷却为用于向冰箱的不同位置提供制冷效果的冷风，冷风通过风机300抽吸至风腔10内，随后例如通过第一控风装置送至储藏区域220，最后从储藏区域220经回风口80再次返回以再次经制冷装置70冷却并形成循环路径。
在将第二控风装置设置在回风口80处时，可以将第二控风装置设置在从回风口80送至制冷装置70的路径上，以控制送回制冷装置70冷却的风量。
本发明的冰箱，通过控风装置30可以实现不同送风模式，例如对某个或某些储藏区域220局部调节温度、集中降温，并且能够提高储藏区域220在时间、空间上的温度均匀性。
需要说明的是，虽然以上结合冰箱的具体应用说明了控风装置30的输送冷风的实例，但可以理解的，控风装置30也可以用于其它需要控制风量的场合，例如常温风、热风等。此外，控风装置30也可以用于输送气液混合物(例如冰箱内调湿时输送的具有湿度的冷空气)。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型。本发明包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
