以下基于实施例对本发明进行描述，但是本发明并不仅仅限于这些实施例。为了避免混淆本发明的实质，公知的方法、过程、流程、元件并没有详细叙述。
此外，本领域普通技术人员应当理解，在此提供的附图都是为了说明的目的，并且附图不一定是按比例绘制的。
除非上下文明确要求，否则整个说明书和权利要求书中的“包括”、“包含”等类似词语应当解释为包含的含义而不是排他或穷举的含义；也就是说，是“包括但不限于”的含义。
在本发明的描述中，需要理解的是，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请提供了一种空气调节系统，用于对室内空间尤其是厨房内空间进行空气调节，当然，可以理解的是，该空气调节系统也适用于其他存在同样的空气质量问题的室内空间中。
空气调节系统包括室内机主体1，室内机主体1用于执行空调的制冷、制热、除湿等常规功能，室内机主体1包括腔室和设置在腔室内的换热器、风机等常规装置，空气调节系统还包括能够将室内空间与腔室连通的至少一个回风口，用于室内机主体1的回风，该至少一个回风口包括第一回风口2，室内机主体1位于室内空间的上部，可以理解的是，此处的上部包括室内空间的顶部区域，第一回风口2位于室内空间的下部，可以理解的是，此处的下部包括室内空间的底部区域，即第一回风口2与室内空间的下部空间连通，如此，即使室内空间例如厨房中有油烟存在，热的油烟也会位于室内空间的上部，而通过位于室内空间的下部的第一回风口2进行回风能够有效避免油烟进入室内机主体1，从而保证室内机主体1内部的洁净度，延长空气调节系统的使用寿命。
进一步地，回风口还包括位于室内空间的上部的第二回风口3，即第二回风口3与室内空间的上部空间连通，空气调节系统还包括第一开关装置4，第一开关装置4用于将腔室与第一回风口2和第二回风口3中的至少一个连通，即，第一开关装置4可以构造为当腔室与第一回风口2连通时，不与第二回风口3连通，而当腔室与第二回风口3连通时，不与第一回风口2连通，第一开关装置4还可以构造为可以将腔室仅与第一回风口2连通，将腔室仅与第二回风口3连通，也可以将腔室同时与第一回风口2和第二回风口3连通，还可以使腔室不与第一回风口2 以及第二回风口3连通。如此，当室内空间内有油烟时，可以采用第一回风口2进行回风，以避免油烟进入室内机主体1内，而当室内空间没有油烟且室内机主体1进行制冷时，可以采用第二回风口3进行回风，以保证室内机主体1对室内空间的制冷效率(因为冷空气会下沉，采用下部的第一回风口2回风不利于热空气返回到室内机主体1换热)。可以理解的是，当室内机主体1进行制热时，也可以采用第一回风口2进行回风，以保证室内机主体1对室内空间的制热效率(因为热空气会上浮，采用上部的第二回风口3回风不利于冷空气返回室内机主体1换热)。
优选地，当该空气调节系统应用于厨房中时，第一回风口2可以设置在厨房内的橱柜上或者设置在靠近厨房地面的腔壁上，第二回风口3设置在厨房的天花板上或者设置在靠近天花板的腔壁上，以保证厨房内空间的整洁。
进一步地，为了方便回风口的设置，优选地，空气调节系统还包括与腔室上的进风口11连通的风道结构5，将回风口设置在风道结构5上，如此，使得室内机主体1的位置以及方位状态的设置更加灵活，室内机主体1可以是立式放置(参照图3)也可以是卧式放置(参照图2)，可以设置在天花板上，也可以设置在橱柜内，室内机主体1的结构例如可以为座吊机，可以根据实际情况选择安装方式，也可以为户式机。
在一个具体的实施例中，风道结构5包括与室内机主体1相连的主风道部51和与主风道部51相连的多个分支风道部，主风道部51与分支风道部可以为一体结构，也可以通过粘接、焊接等方式形成不可拆卸的连接，还可以是形成可拆卸连接，例如通过卡接、插接、紧固件连接等方式进行连接，如此，方便风道结构的拆卸，在一个具体的实施例中，主风道部51上设置有多个接口，分支风道部插入接口中，以实现主风道部51与分支风道部的连接。进一步地，各个回风口分别设置在分支风道部上，例如，在图1所示的实施例中，多个分支风道部包括第一分支风道部52和第二分支风道部53，第一回风口2设置在第一分支风道部52上，具体地，第一分支风道部52的一端通过第一接口511与主风道部51连接，第一回风口2设置在第一分支风道部52的另一端，通过第一分支风道部52将第一回风口2引至室内空间的下部，第二回风口3设置 在第二分支风道部53上，具体地，第二分支风道部53的一端通过第二接口512与主风道部51连接，第二回风口3设置在第二分支风道部53的另一端，通过第二分支风道部53将第二回风口3引至室内空间的上部。当然，可以理解的是，在同一分支风道上也可以设置多个回风口，通过对不同回风口的封堵来实现不同位置的回风。
由于通常情况下室内机主体1设置在空间的顶部或者靠近顶部的上部区域，因此第一分支风道部52的长度较长，为了节省空间，优选地，第一分支风道部52嵌设在墙体中。
进一步地，第一开关装置4可以是设置在第一回风口2以及第二回风口3处或者设置在各个分支风道部内的风阀，为方便控制，优选地，第一开关装置4设置在主风道部51的内腔中，在一个实施例中，第一开关装置4包括设置在第一接口511与第二接口512之间的第一隔板41、与第一隔板41铰接的第一挡板42以及驱动第一挡板42转动的第一驱动装置(图中未示出)，当第一挡板42向第一接口511方向翻转并抵靠在第一接口511与进风口11之间的腔壁上时，第一挡板42将第一接口511与进风口11断开，第二接口512与进风口11连通，此时通过第二回风口3回风，而当第一挡板42向第二接口512方向翻转并抵靠在第二接口512与进风口11之间的腔壁上时，第一挡板42将第二接口512与进风口11断开，第一接口511与进风口11连通，此时通过第一回风口2回风。
进一步地，空气调节系统还包括能够将第二回风口3与室外空间连通的排风通道6，如此，室内空间中的空气可以经第二回风口3和排风通道6排至室外，当室内有油烟时，聚集到天花板附近的油烟可以经第二回风口3和排风通道6排至室外，从而有效避免油烟将天花板污染。
进一步优选地，空气调节系统还包括气流驱动装置7，用于驱动室内空间内的空气经第二回风口3和排风通道6排至室外空间，气流驱动装置7能够对油烟排出提供助力，使得油烟能够尽快排出室外，进一步避免油烟凝结到天花板上，气流驱动装置7例如可以为风机，其优选设置在第二分支风道部53的内腔中，以对油烟的运动提供尽可能大的驱动力。
进一步地，空气调节系统还包括第二开关装置8，用于将排风通道6与第二回风口3之间连通或切断，第二开关装置8例如可以为风阀，如图2和3所示，第二开关装置8包括第二挡板81和驱动第二挡板81转动的第二驱动装置(图中未示出)，第二挡板81可以如图2所示与排风通道6的一侧边缘铰接，当第二驱动装置驱动第二挡板81抵靠在排风通道6的与一侧边缘相对的另一侧边缘上时，第二挡板81将排风通道6关闭，第二回风口3与排风通道6不连通，而当第二驱动装置驱动第二挡板81抵靠在第一隔板41上时，第二挡板81将排风通道6打开，第二回风口3与排风通道6连通且第二回风口3不会与进风口11连通。在另一个实施例中，如图3所示，第二开关装置8还包括第二隔板82，第二接口512与排风通道6并排设置，第二隔板82设置在第一隔板41与排风通道6之间，第二隔板82的一侧边与主风道部51的一侧腔壁相连，第二挡板81与第二隔板82的相对的另一侧边铰接，当第二挡板81抵靠在第二接口512与排风通道6之间的腔壁上时，第二挡板81将排风通道6关闭，第二回风口3与排风通道6不连通，而当第二挡板81抵靠在于主风道部51的一侧腔壁相对的另一侧腔壁上时，第二挡板81将第二回风口3与排风通道6连通且第二回风口3不会与进风口11连通。
进一步地，在第二回风口3处设置有油烟检测装置9，油烟检测装置9例如可以设置在第二分支风道部53内，通过油烟检测装置9的检测值来判断室内空间内的是否有油烟，以此进行相应控制，例如，当油烟检测装置9的检测值大于或等于预定值时，控制第一开关装置4将腔室仅与第一回风口2连通，此时室内机主体1通过第一回风口2回风，以避免过多的油烟进入室内机主体1内；当油烟检测装置9的检测值小于预定值且室内机主体1运行制冷时，控制第一开关装置4将腔室仅与第二回风口3连通，以保证室内机主体1的制冷效果；当油烟监测装置9的检测值小于预定值且室内机主体1运行制热时，控制第一开关装置4将腔室仅与第一回风口2连通，以保证室内机主体1的制热效果。
进一步优选地，当油烟检测装置9的检测值大于或等于预定值时，将排风通道6打开，以使得第二回风口3与室外空间连通，同时还可以将气流驱动装置7开启，如此，使得上升到上部空间内得油烟能够快速 经第二回风口3和排风通道6排出室外，以保证天花板的洁净。
本申请提供的空气调节系统具有位于室内空间的下部的第一回风口2，如此，即使室内空间中有油烟存在，热的油烟也会位于室内空间的上部，而通过位于室内空间的下部的第一回风口2进行回风能够有效避免油烟进入室内机主体1，从而保证室内机主体1内部的洁净度，延长空气调节系统的使用寿命。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各优选方案可以自由地组合、叠加。
应当理解，上述的实施方式仅是示例性的，而非限制性的，在不偏离本发明的基本原理的情况下，本领域的技术人员可以针对上述细节做出的各种明显的或等同的修改或替换，都将包含于本发明的权利要求范围内。
