具体实施方式
下面详细描述本发明的实施例，本发明的实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
本发明提供一种空调器的控制方法，图1是根据本发明一实施例的一种空调器的控制方法的流程图。参见图1并参考图2至图10，空调器包括空调室内机，空调室内机包括壳体。壳体上开设有换热风出风口11、第一出风口21、第一室内风进风口12和第二室内风进风口23，换热风出风口11与第一出风口21均呈长条状，第一出风口21处于换热风出风口11一侧，以使第一出风口21的出风能够与换热风出风口11的出风混合。换热风出风口11与第一室内风进风口12连通，第一出风口21与第二室内风进风口23连通。空调器的控制方法包括：在通新风时，使第一出风口21和换热风出风口11同时运转。
通新风时，尤其是在室外新风温度与室内环境温度差值较大时，新风直接吹在用户身上会使得用户不舒服，在通新风时，使第一出风口21和换热风出风口11同时运转，使得第一出风口21吹出的室内风和换热风出风口11吹出的换热风能跟新风混合，从而使新风温度更接近室内环境温度，特别是新风温度较低时，使得新风不硬，进而提高了空调器的舒适性。
在本发明的一些实施例中，如图4所示，所述空调器的控制方法还包括：获取室内空间与空调器的最大距离，根据最大距离确定换热风出风口11的风速和第一出风口21的风速，以在至少两个不同的最大距离中，较大的最大距离对应的换热风出风口11的风速和第一出风口21的风速均比较大。
本文中提及的室内空间与空调器的最大距离是指空调器与其所在的室内空间的边缘各点的距离中的最大值。本领域技术人员可以理解，室内空间的大小以及空调器在室内空间中的位置均会影响该最大距离。例如，对于同一室内空间，空调器位于该室内空间的中心的情况下的该最大距离与空调器位于该室内空间的一侧的情况下的该最大距离是不一样的，具体来说前者小于后者。再例如，在空调器均位于室内空间的中心的情况下，室内空间的尺寸越大，则该最大距离越大。
本发明实施例中根据获取的最大距离确定换热风出风口11的风速和第一出风口21的风速，具体地，使换热风出风口11的风速和第一出风口21的风速与该最大距离正相关，即，相对于不同的最大距离，较大的最大距离对应的换热风出风口11的风速和第一出风口21的风速均比较大。
第一出风口21的室内风与换热风出风口11的换热风不仅可以与新风混合。通过第一出风口21的出风与换热风出风口11的出风混合，还增大了空调器的出风速度，提高了送风距离，又增大了出风量，从而提高了空调器的舒适性。
进一步地，在本发明的一些实施例中，当最大距离小于或等于第一预设距离时，换热风出风口11的风速为第一风速，第一出风口21的风速为第二风速。当最大距离大于第一预设距离且小于或等于第二预设距离时，换热风出风口11的风速为第三风速，第一出风口21的风速为第四风速。当最大距离大于第二预设距离时，换热风出风口11的风速为第五风速，第一出风口21的风速为第六风速。第二预设距离大于第一预设距离。第五风速大于第三风速，第三风速大于第一风速。第六风速大于第四风速，第四风速大于第二风速。随着最大距离的增加，同时提高换热风出风口11的出风速度和第一出风口21 的出风速度，既保证了空调器的出风速度，又可使换热风出风口11的出风速度不需要增加太多，进而使得空调器的出风噪音不会增加太大，提高了空调器的舒适性。这里的第一预设距离为3m至4m，优选地，第一预设距离为3.5m。第二预设距离为5m至7m，优选地，第二预设距离为6m。
在本发明的一些实施例中，如图5、图7和图10所示，壳体上还开设有新风进风口33、第三室内风进风口34、第二出风口22和第三出风口36，第二出风口22呈长条状。第二出风口22处于所述第一出风口21的上侧或下侧，以使第二出风口22的出风能够与换热风出风口11的出风混合。壳体内设置有混风风道和蒸发器13，混风风道与新风进风口33和第三室内风进风口34均连通。其中，空调器的控制方法还包括：在通新风时，获取室外新风温度。根据室外新风温度与室内环境温度的差值，确定：是同时开启新风进风口33和第三室内风进风口34，以使新风和室内风同时进入混风风道，还是仅开启新风进风口33，以仅使新风进入混风风道。和/或，是使混风风道与第二出风口22导通，以使混风风道的风经第二出风口22流出后与流出换热风出风口11的热交换风混合，进而在新风和室内风同时进入混风风道时，使新风先与室内风混合，混合后的风与换热后的室内风混合。还是使混风风道与第三出风口36导通，以在混风风道的风经第三出风口36流出后，使来自混风风道的风中的至少部分进入第一室内风进风口12，进而在新风和室内风同时进入混风风道时，使新风先与室内风混合，混合后的风再次与进入第一室内风进风口12的室内风混合，接着与蒸发器13进行热交换，后流出换热风出风口11。和/或，换热风出风口11的出风温度。
在通新风时，根据室外新风温度与室内环境温度的差值，确定是仅仅通新风还是通新风和室内风经过混风风道之后的混合风，比如，当室外新风温度与室内环境温度的差值不大时，而且第一出风口21和换热风出风口11的出风也可以跟新风混合，从而降低新风温度，在风量一定的情况下，仅通新风可以尽快满足客户对新风的需求。当室外新风温度与室内环境温度的差值比较大时，仅靠第一出风口21和换热风出风口11的出风跟新风混合已经不能明显改变新风的温度，这是就需要引入新风的同时再引入室内风，新风和室内风经过混风风道的混合，出风的温度更接近室内环境温度，通新风和室内风经过混风风道的混合风会使用户感觉舒适。进一步地，根据室外新风温度与室内环境温度的差值，确定混合风道流出的风是从第二出风口22流出还是从第三出风口36流出，可以进一步地保证空调器引入新风时出风舒适。比如，混合风道流出的风可以从第二出风口22流出后与换热风出风口11的热交换风混合，可以使新风或者新风和室内风的混合风温度更接近室内环境温度，使出风舒适。当室外新风温度与室内环境温度的差值比较大时，新风和室内风的混合风仍然偏热或偏冷，此时新风和混合风道流出的风也可以从第三出风口36流出后，然后，至少部分再进入第一室内风进风口12与进入第一室内风进风口12的室内风再做一次混合，然后通过蒸发器13换热，以换热风的形式从换热风出风口11流出，同样可以使新风温度接近空调器的设定温度，使出风舒适。更进一步地，根据室外新风温度与室内环境温度的差值来确定换热风出风口11的出风温度，当室外新风温度大于室内环境温度，此时空调器为制冷模式，差值越大，越要降低换热风出 风口11的出风温度。当室外新风温度小于室内环境温度，此时空调器为制热模式，差值越大，越要提高换热风出风口11的出风温度。上述控制方法既可以保证空调器引入新风后出风舒适，从而能够改善用户在使用空调器引入新风时的体验。
进一步地，在本发明的一些实施例中，如图1所示，当室外新风温度与室内环境温度的差值小于或等于第一预设温度差值时，仅开启新风进风口33，同时使混风风道与第二出风口22导通。也就是说，室外新风温度和室内环境温度差距不大，仅开启新风进风口33，新风经过混风风道从第二出风口22流出，且与换热风出风口11的出风混合，保证流出的新风的舒适性。需要注意的是，本说明书中室外新风温度与室内环境温度的差值始终为正值，即当室外新风温度高于室内环境温度时，差值为室外新风温度减去室内环境温度，当室外新风温度低于室内环境温度时，差值为室内环境温度减去室外新风温度。第一预设温度差值为1℃至3℃，优选地，第一预设温度差值为2℃。
进一步地，在本发明的一些实施例中，如图2所示，当室外新风温度与室内环境温度的差值大于第一预设温度差值且小于或等于第二预设温度差值时，同时开启新风进风口33和第三室内风进风口34，使混风风道与第三出风口36导通，且当室外新风温度大于室内环境温度时，换热风出风口11的出风温度为室内环境温度减去第一预设温度值，当室外新风温度小于室内环境温度，换热风出风口11的出风温度为室内环境温度加上第二预设温度值。第二预设温度差值大于第一预设温度差值。此时，需要同时开启新风和室内风混合，以使出经过混合风道的出风更接近室内环境温度。同时还需要使得至少部分的新风和室内风进入第一室内风进风口12，进行换热。第二预设温度差值为3℃至5℃，优选地，第二预设温度差值为4℃。第一预设温度值为1℃至3℃，优选地，第一预设温度值为2℃。第二预设温度值为5℃至7℃，优选地，第二预设温度值为6℃。
进一步地，在本发明的一些实施例中，如图3所示，当室外新风温度与室内环境温度的差值大于第二预设温度差值时，同时开启新风进风口33和第三室内风进风口34，且使混风风道与第三出风口36导通，且当室外新风温度大于室内环境温度时，换热风出风口11的出风温度为室内环境温度减去第三预设温度值，当室外新风温度小于室内环境温度，换热风出风口11的出风温度为室内环境温度加上第四预设温度值。三预设温度值大于第一预设温度值，第四预设温度值大于第二预设温度值。
随着室外新风温度与室内环境温度的差值增大，需要相应地增大空调器的制冷或者制热能力，以在通新风的同时，避免室内环境温度的大幅波动。第三预设温度值为3℃至5℃，优选地，第三预设温度值为4℃。第四预设温度值为8℃至12℃，优选地，第四预设温度值为10℃。
在本发明的一些实施例中，空调器的控制方法还包括：获取室内二氧化碳浓度。当室内二氧化碳浓度大于或等于预设浓度时，确定需要通新风，并启动通新风。当室内二氧化碳浓度小于预设浓度时，关闭新风进风口33和第三室内风进风口34，或者关闭新风进风口33，以停止通新风。这里的预设浓度可以根据用户的需求自行设定。当然，在本发明的另一些实施例中，也可以根据室内PM2.5的浓度与预设PM2.5的浓度做对比或者氧气的浓度与预设氧气的浓度做对比来确定是否需要通新风。
在本发明的一些实施例中，如图5所示，换热风出风口11和第一出风口21之间设置有第一引风间隔，以在换热风出风口11和/或第一出风口21出风时，与来自第一引风间隔的风混合。换热风出风口11和第二出风口22之间设置有第二引风间隔，以在新风和室内风同时进入混风风道，使新风先与室内风混合，并经第二出风口22流出时，混合后的风与来自第二引风间隔的风以及换热后的室内风混合。
在本发明的一些实施例中，壳体内设置有第一风道、第二风道和第三风道，第一风道、第二风道和第三风道均呈竖条状，第二风道设置于第三风道的上侧，且第二风道和第三风道的高度均小于第一风道。第一风道与换热风出风口11连通，第二风道与第一出风口21连通，第三风道与第二出风口22连通。第一出风口21和第二出风口22设置于换热风出风口11一侧，以使第一出风口21和第二出风口22的出风和换热风出风口11的换热出风混合。
如图9所示，第一风道内设置有蒸发器14和换热风机13，换热风机13引导风从第一室内风进风口12进入第一风道，经过蒸发器后，从换热风出风口11吹出。换热风机13为贯流风机。
第二风道内设置有引风风机24，引风风机24引导风从第二室内风进风口23进入第二风道，并从第一出风口21吹出。引风风机24为贯流风机。
如图8所示，第三风道的下端设置有进风口，第三风道内设置有沿竖向排列的多个导流片25，每个导流片25从前至后延伸，且后端向下弯折形成导流弯折部，且位置越靠上的导流片的前、后端距离越大。风从下向上流动，在遇到每个导流片25后，被其导流弯折部引导，逐渐从向上流动变化为向前流动。因此，导流弯折部起到改变风流动方向的作用，使得风的转向更加平缓、风力损失更小。导流弯折部与导流片25的其余部分之间以圆角过渡。进一步地，考虑到风从第二风道底部进入，可能会导致第二出风口22中部或上部的出风量偏小。因此，本发明实施例特别在第二风道内设置竖向排列的多个导流片25，并且位置越靠上的导流片的前、后端距离越大，使得第二出风口22在竖向各处的出风更加均匀。
第一风道和第二风道、第三风道间隔设置，第一引风间隔和第二引风间隔连通，以使第一风道和第二风道、第三风道之间形成贯穿壳体的引风间隔15。
在本发明的一些实施例中，如图5至7所示，壳体包括：第一出风柱10、第二出风柱20和下壳30。第一出风柱10呈竖直柱状，第一风道设置于第一出风柱10内，第一出风柱10的前侧开设有换热风出风口11。第一出风柱10的后壁和侧壁上设置有与换热风出风口11连通的第一室内风进风口12。第二出风柱20呈竖直柱状，第二风道和第三风道设置于第二出风柱20内，第二出风柱20的前侧开设有第一出风口21和第二出风口22。第二出风柱20的下端设置有与第二出风口22连通的进风口。第二出风柱20的上部的后壁和侧壁上设置有与第一出风口21连通的第二室内风进风口23。第二出风柱20设置于第一出风柱10的横向一侧。第二出风柱20与第一出风柱10之间构成引风间隔，以便换热风出风口11和/或第一出风口21出风和/或第二出风口22出风时依靠负压作用带动引风间隔15内的空气向前流动。第一出风柱10和第二出风柱20设置于下壳30的顶端。 如图10所示，新风进风口33、第三室内风进风口34与第三出风口36设置于下壳30的周壁上，第三出风口36设置于第一室内风进风口12附近。第三室内风进风口34设置有第一风门，用于开合第三室内风进风口34。如图5所示，下壳30内设置有风机31，混风通道设置于风机31内，风机31的进风口与新风进风口33和第三室内风进风口34连通，风机的出风口通过第二风门32择一地与进风口或第三出风口36连通。风机31为离心风机。

至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
