具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“上”、“下”、“左”、“右”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接或彼此可通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
下面参考附图描述根据本发明实施例的六通换向阀100，六通换向阀100可应用在空调室外机1000中，当空调室外机1000与空调室内机一起形成空调器时，六通换向阀100可在空调器中换向以实现不同模式之间的切换，以便于调节冷媒流路中的冷媒流向。
如图1-图2所示，根据本发明实施例的六通换向阀100，可以包括阀体1、阀芯2和先导阀组件4。其中，阀体1内限定出阀腔5，阀腔5具有相对设置的第一侧壁11和第二侧壁12，阀体1上设有第一连接管至第六连接管A-F，第一连接管A至第六连接管F可与空调室外机1000中的其他管路分别连通，以便于冷媒的流通。
阀芯2可移动地设在阀腔5内，也就是说，阀芯2在阀腔5内是可移动的，由此，通过阀芯2在阀腔5内的移动可实现六通换向阀100的换向功能，从而实现空调器内冷媒的换向流通。
阀芯2的两个移动端与阀腔5的内周壁之间限定出两个阀室3以使得阀芯2由两个阀室3的压力差驱动移动，也就是说，阀芯2在阀腔5内的移动动作是由两个阀室3的压力差驱动的，具体而言，当两个阀室3中有一个阀室3内的压力较大时，会使得阀芯2朝向另一个压力较小的阀室3移动，最终达到压力平衡，从而以此方式实现阀芯2的移动，进而实现六通换向阀100的换向功能。
先导阀组件4分别与两个阀室3相连以切换两个阀室3的压力。可选地，先导阀组件4可以通过毛细管与两个阀室3相连以切换两个阀室3的压力。例如，当空调器需要在制冷模式和制热模式之间切换时，通过先导阀组件4切换两个阀室3的压力，以使得阀芯2朝向压力小的一侧的阀室3移动，从而实现六通换向阀100的换向，并以此改变冷媒的流通方向，进而实现空调器的制冷功能或制热功能。
阀芯2与第一侧壁11之间限定出第一腔室21，阀芯2与第二侧壁12之间限定出第二腔室22，阀芯2与第一侧壁11和第二侧壁12限定出第三腔室23，第一连接管A与第一腔室21常连通，第二连接管B与第二腔室22常连通，也就是说，无论六通换向阀100是否换向，第一连接管A始终与第一腔室21连通，第二连接管B始终与第二腔室22连通。
阀芯2移动以使得第三连接管C和第四连接管D中的其中一个与第一腔室21连通且另一个与第三腔室23连通、第五连接管E和第六连接管F中的其中一个与第二腔室22连通且另一个与第三腔室23连通，也就是说，当阀芯2移动到第三连接管C与第一腔室21连通时，第四连接管D和第五连接管E与第三腔室23连通，第六连接管F与第二腔室22相连通，当阀芯2移动到第四连接管D与第一腔室21连通时，第三连接管C和第六连接管F与第三腔室23连通，第五连接管E与第二腔室22连通。
具体而言，通过先导阀组件4切换两个阀室3的压力，以使得阀芯2朝向压力小的一侧的阀室3移动。例如，如图1所示，当阀芯2向左移动，六通换向阀100处于换向前，此时第一连接管A和第三连接管C与第一腔室21连通，第二连接管B和第六连接管F与第二腔室22连通，第四连接管D和第五连接管E与第三腔室23连通。当阀芯2向右移动，六通换向阀100换向后，此时第一连接管A和第四连接管D与第一腔室21连通，第二连接管B和第五连接管E与第二腔室22连通，第三连接管C和第六连接管F与第三腔室23连通。可以理解的是，针对阀芯2的左右移动仅是根据图1-图2的示例性说明，不能理解为对阀芯2的一种限制。为了便于描述，下文中提及的阀芯2的移动均以向左或向右移动进行示例性说明。
需要说明的是，为了便于清楚地描述六通换向阀100的换向原理，以下将六通换向阀100结合在空调室内机及空调器中进行说明。
根据本发明实施例的空调室外机1000，空调室外机1000具有外机输出口200和外机输入口300，在外机输出口200和外机输入口300之间连接有空调室内机。空调室外机1000可以包括压缩机400、上述的六通换向阀100和室外换热器500。
具体地，压缩机400具有排气口401和回气口402，冷媒从回气口402进入到压缩机400内部，经压缩机400压缩后形成高温高压的冷媒，从排气口401排出。需要进行说明的是，压缩机400的结构和工作原理等均为现有技术，这里不再进行详细描述。
第一连接管A与排气口401相连，第二连接管B与回气口402相连，第三连接管C与外机输出口200相连，第五连接管E与外机输入口300相连，从而将六通换向阀100连通在空调室外机1000的冷媒流路中以便于对冷媒流向的切换。
室外换热器500的两端分别与第四连接管D和第六连接管F相连，从而将室外换热器500连接在冷媒回路中以便于冷媒流过室外换热器500与室外环境交换热量。
具体而言，如图1和图3所示，当空调器处于制热模式时，先导阀组件4切换两个阀室3的压力以使得阀芯2向左移动，此时第一连接管A和第三连接管C与第一腔室21连通，第二连接管B和第六连接管F与第二腔室22连通，第四连接管D和第五连接管E与第三腔室23连通，经压缩机400的排气口401排出的高温高压的冷媒经过第一连接管A进入到第一腔室21内，随后从第三连接管C流出，经过外机输出口200流向空调室内机，并在空调室内机中与室内环境换热，随后从空调室内机排出的冷媒经过外机输入口300和第五连接管E进入到第三腔室23内，接着从第四连接管D流出，流向室外换热器500，在室外换热器500内与室外环境换热，从室外换热器500流出后经过第六连接管F进入到第二腔室22内，并从第二连接管B流出，经过压缩机400的回气口402返回到压缩机400，以此往复，形成制热循环。
如图2和图4所示，当空调器处于制冷模式时，先导阀组件4切换两个阀室3的压力以使得阀芯2向右移动，此时第一连接管A和第四连接管D与第一腔室21连通，第二连接管B和第五连接管E与第二腔室22连通，第三连接管C和第六连接管F与第三腔室23连通，经压缩机400的排气口401排出的高温高压的冷媒经过第一连接管A进入到第一腔室21内，接着从第四连接管D流出，进入到室外换热器500，在室外换热器500内与外界环境换热，冷媒从室外换热器500流出后，经过第六连接管F进入到第三腔室23内，接着从第三连接管C流出，经过外机输出口200流向空调室内机，在空调室内机内与室内环境换热，随后从空调室内机流出的冷媒经外机输入口300和第五连接管E流入第二腔室22内，然后从第二连接管B流出，经过压缩机400的回气口402返回到压缩机400，以此往复，形成制冷循环。
根据本发明实施例的六通换向阀100，通过在六通换向阀100上设置第一连接管A到第六连接管F，且将阀芯2可移动地设在阀腔5内以实现六通换向阀100的换向功能，避免了在空调室外机1000中使用多个四通阀以实现与六通换向阀100相同的作用，这在一定程度上降低了换向阀的成本，简化了空调室外机1000中管路的连接。
根据本发明实施例的空调室外机1000，通过设置上述的六通换向阀100，可以至少在一定程度上降低空调室外机1000的成本，简化空调室外机1000中管路的连接，优化空调室外机1000的结构，提高空调室外机1000连接的可靠性。
根据本发明的一些实施例，第一连接管A、第三连接管C和第四连接管D分别设在第一侧壁11上，第二连接管B、第五连接管E和第六连接管F分别设在第二侧壁12上，从而便于第一连接管A至第六连接管F分别与对应的第一腔室21到第三腔室23相连通，以实现六通换向阀100的换向。
在本发明的一些实施例中，阀芯2包括两个间隔设置的阻隔块24和滑块25。其中，两个阻隔块24分别与阀腔5的内周壁之间限定出两个阀室3，从而便于阀芯2在阀腔5内移动以实现六通换向阀100的换向，进而改变空调器中的冷媒的流向。
滑块25设在两个阻隔块24之间，滑块25通过连接杆26分别与两个阻隔块24相连，滑块25与第一侧壁11之间限定出第一腔室21，滑块25与第二侧壁12之间限定出第二腔室22，滑块25、两个连接杆26和两个阻隔块24与阀腔5的内壁之间限定出第三腔室23，具体而言，在先导阀组件4切换两个阀室3的压力后，压力较大一侧的阀室3驱动阻隔块24且阻隔块24带动滑块25朝向压力小的一侧阀室3移动，以使第一腔室21、第二腔室22和第三腔室23分别与对应的第一连接管到第六连接管A-F连通，从而实现六通换向阀100的换向，进而调整冷媒回路中冷媒的流向。
可选地，两个阻隔块24、滑块25和两个连接杆26为一体成型件，由此，不但便于阻隔块24、滑块25和两个连接杆26的生产加工制造，而且节约了阀芯2的生产成本，同时还可以在一定程度上提高阻隔块24、滑块25和两个连接杆26之间的连接强度，延长阀芯2的使用寿命。
可选地，阀体1的横截面形成为圆形，从而便于六通换向阀100与空调室外机1000中的其它管路的连通。
根据本发明实施例的空调器，包括上述的空调室外机1000。
根据本发明实施例的空调器，通过设置上述的空调室外机1000，不但可以在一定程度上降低空调器的成本，而且简化了空调室外机1000中管路的连接，优化了空调室外机1000的结构，提高了空调室外机1000连接的可靠性。
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“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，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”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者 特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
