背景技术
随着社会发展以及人们的生活水平不断提高，人们对于生活质量的要求也越来越高。人们越来越重视生活品质，空调器已经成为人们日常生活中不可或缺的电气设备之一。
然而，现有的空调器在使用的过程中，由于用户的呼吸作用，室内空气的二氧化碳浓度越来越高，氧气浓度会越来越低，若用户长期处在这种环境中，会对身体有极大危害，若用户通过打开门窗的方式来进行气体交换的话，又会造成资源的浪费。
虽然，现在已经有了带有新风组件的空调器，可以进行室内污浊空气与室外新鲜空气的交换，但在运行时容易将刚排入室内的新鲜空气排到室外，造成气体交换的效率不高。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决上述问题的带有新风组件的空调器室内机。
本发明的一个目的是提供一种提升气体交换效率的带有新风组件的空调器室内机。
本发明的一个进一步的目的是提升这种空调器室内机带来的温度体验。

具体实施方式
本实施例提供了一种空调器室内机10，图1是根据本发明一个实施例的空调器室内10的侧面剖视图，图2是根据本发明一个实施例的空调器室内机10的后部示意图。空调器室内机10包括室内机机壳100以及新风组件 200，其中，新风组件200设置于室内机机壳100内的底部，将新风组件200设置于室内机机壳100内的底部是由于二氧化碳在室内是自下往上积累的，利于将二氧化碳浓度高的室内空气排出去，提高效率。
图3是根据本发明一个实施例的空调器室内机10的新风组件200的结构示意图，图4是根据本发明一个实施例的空调器室内机10的新风组件200的后部示意图。新风组件200包括风口模块210，其中风口模块210包括风口外壳211。
风口外壳211的后板形成有浊风排风口212，其中浊风排风口212连通浊风排风管，以与室外环境相连。另外，风口外壳211的侧板开有连通室内的浊风进风口214，浊风进风口214至浊风排风口212形成有浊风风道，这种浊风进风口214以及浊风排风口212的设置方式使得室内空气的循环路径增多，使得室内环境的温度变化缓慢，提高用户的温度体验。浊风是指室内环境空气，新风是指室外环境空气。
风口模块210还包括设置于浊风排风口212处的排风风机216，排风风机216用于形成使室内空气通过浊风进风口214进入浊风风道，再通过浊风排风口212进入浊风排风管的气流，如图4中实线箭头所示的方向为室内空气可以通过浊风进风口214通过浊风风道进入浊风排风口212的线路图，室内空气从浊风排风口212进入浊风排风管以排到室外，在本发明的一些实施例中，排风风机216的送风方向设置为沿浊风排风口212的延伸方向，且排风风机216为轴流风机，其轴线与浊风排风口212的中心线相对。
风口外壳211的后板还形成有新风进风口213，新风进风口213连通新风进风管，以与室外环境相连，新风进风管口处可设置有过滤网，以过滤室外空气中较大的异物，从而避免这些杂质污染室内空气，并有效地避免了这些杂质对新风组件200内部各部件的损害。
在本发明的一些实施例中，浊风排风口212以及新风进风口213设置于风口外壳211的后板的底部且处于同一高度处，通过这种浊风排风口212以及新风进风口213的设置方法可以减小风口模块210的高度，以节省风口模块210占用的室内机机壳100的空间。浊风进风口214的高度设置为高于浊风排风口212以及新风进风口213的高度，由于浊风进风口214与浊风排风口212的高度不同使室内温度适宜的空气不会很快的排出去，不会使室内空气的温度产生巨大的变化，提高用户的温度体验。
另外，新风进风口213连接有通向所述新风组件200外部的新风风道，如图4中虚线箭头所示的方向为室外空气通过新风风道的线路图。在本发明的一些实施例中，新风风道直接与室内连通，以直接向室内供给新鲜的空气。
在本发明的另一些实施例中，室内机机壳100内部限定有用于布置换热器的换热室110，并且新风风道连通至换热室110。
空调器在制冷运行时，在压缩机中冷媒被压缩成高温高压的冷媒蒸气，冷媒蒸气经过进入空调器室外机，冷媒蒸气在空调器室外机中冷凝放热成为高温高压的液体，再经过节流装置后降压成低温低压的气液混合物进入空调器室内机10的换热室110，冷媒在其中吸热蒸发后再次进入压缩机，以完成制冷循环。由于空调器的制冷循环本身是本领域技术人员所习知的，在此不做赘述。
通过使新风风道连通至换热室110，可以使室外对用户造成不良温度体验的空气的温度产生变化，使其换热成为适宜人体的温度再通过出风口120排到室内，以提升用户的温度体验。
另外，本实施例的浊风风道与新风风道的延伸方向交叉设置，这种设置方式使得空调器室内机10在运行时避免将刚排入室内的新鲜空气排到室外，以提高气体交换的效率。
在本发明的一些实施例中，风口模块210还包括设置于风口外壳211内与浊风进风口214相对的位置处的全热交换芯215，且其内部形成有部分浊风风道以及部分新风风道，以使得室内空气通过全热交换芯215内的部分浊风风道时将室内空气的热量传递给通过全热交换芯215内的部分新风风道的室外空气，从而避免热量的浪费，使得空调器室内机10更加节能环保。
在本发明的一些实施例中，浊风进风口214设置于靠近新风进风口213的侧板上。这种浊风进风口214的设置方式使得浊风风道的路径更长，从而使全热交换芯215能充分地将通过全热交换芯215内的部分浊风风道的室内空气的热量传递给通过全热交换芯215内的部分新风风道的室外空气，提高全热交换芯215的利用率。
新风组件200还可以包括设置于风口模块210的上方的送风模块220，送风模块220包括送风壳体221以及新风风机222，送风壳体221内限定出新风风道的延伸段，且新风风机222设置于送风壳体221内的新风风道的延伸段内，用于产生使室外空气沿新风风道运动的气流，且新风风机222也为 轴流风机，其设置为向上送风，以与新风排风口231的位置相配合。在新风风道连通至换热室110的情况下，新风风机222与换热室110内的换热风机共同作用，以更大的风力将经过换热的室外新鲜空气排到室内的各个角落，以使室内温度均匀。
这种排风风机216以及新风风机222的设置方式，使排风风机216与新风风机222位于不同高度处，避免了两个风机的噪音相互叠加造成的不良影响，且实现了对空间的合理利用。
新风组件200还包括设置于送风模块220的上方的出风模块230，出风壳体240的上端形成有新风排风口231。
由于二氧化碳会从室内空间的底部向上积累，这种风口模块210、送风模块220以及出风模块230的设置方式使得浊风进风口214位于整个新风组件200的底部，利于将位于室内空间底部的二氧化碳浓度较高的空气排出去，提高了气体交换的效率。
并且，这种风口模块210、送风模块220以及出风模块230的设置方式使得室外空气从位于底部的新风进风口213进入风口模块210，并直接向上依次经过送风模块220与出风模块230内部，使得室外空气的流向的方向单一，减少了风阻，提高了风量。
图5是根据本发明一个实施例的空调器室内机10的新风组件200的侧视图，图6是根据本发明一个实施例的空调器室内机10的新风组件200的出风模块230的剖视图。出风模块230还包括设置于出风壳体240内的净化滤芯232，用于对经过其的空气做净化处理，净化滤芯232可以由初级滤网、银离子滤网、高效空气过滤器滤网等组成，以过滤室外空气中的可吸入颗粒物等杂质，使排进室内的空气更加清洁。
出风壳体240包括下固定板241以及上固定板242，下固定板241的第一端设置于出风壳体240的前板的内部，其第二端向上倾斜，以部分遮挡出风壳体240内的气流通道，从而进一步减小经过出风模块230的室外空气的风阻，上固定板242一端设置于出风壳体240的前板的内部且位于下固定板241的第一端的上方，其另一端向下倾斜并固定于下固定板241的第一端与第二端之间，且下固定板241、上固定板242用于共同固定净化滤芯232。
这种下固定板241以及上固定板242的设置方式使得净化滤芯232可以倾斜放置，以使室外空气更大程度与净化滤芯232接触，以提高净化滤芯232 的净化效率，进一步提高经过其的室外空气的清洁度。
出风壳体240的前板的上部向出风壳体240外侧弯曲延伸，以在风口模块210、送风模块220以及出风模块230的位置关系以及下固定板241的设置方式减小室外空气经过新风风道的风阻的基础上，提高新风排风口231的出风量。
在本发明的一些实施例中，空调器室内机10可以为柜式空调器室内机，且风口外壳211的后板相对于柜式空调器室内机的后板设置，风口外壳211的侧板相对于柜式空调器室内机的侧板设置。以使新风进风口213以及浊风排风口212朝向柜式空调器室内机的后部，以提高柜式空调器的美观性，且便于安装浊风排风管以及新风进风管，浊风进风口214朝向柜式空调器室内机的侧部。
在本发明的另一些实施例中，空调器室内机10也可以为其他类型的空调器室内机，例如可以为壁挂式空调器室内机，则新风组件200可以设置于壁挂式空调器室内机机壳内的底部，其中壁挂式空调器室内机机壳的底板上形成有供新风进风管、浊风排风管穿过的开口，侧板上形成有浊风进风口214，新风排风口231可以通向其换热室110。
本实施例的空调器室内机10包括室内机机壳100以及新风组件200，其中，新风组件200设置于室内机机壳100内的底部，新风组件200包括风口模块210、设置在风口模块210上方的送风模块220、设置在送风模块220上方的出风模块230，其中风口模块210的风口外壳211后板底部形成有新风进风口213、浊风排风口212，侧板上形成有浊风进风口214，且风口外壳211内有全热交换芯215，浊风排风口212处有排风风机216，送风模块220的送风壳体221内有新风风机222，出风模块230内有倾斜设置有净化滤芯232，且其出风壳体240上方形成有新风排风口231。
在空调器室内机10启动新风模式时，排风风机216运转，室内空气通过浊风进风口214进入浊风风道，其中包括全热交换芯215内形成的部分浊风风道，在通过浊风排风口212进入浊风排风管以排到室外，同时，新风风机222运转，室外空气经过新风进风管进入新风进风口213，其中在新风进风管处通过过滤网过滤较大的杂质，并进入新风风道，包括全热交换芯215内形成的部分新风风道，并与全热交换芯215内形成的部分浊风风道内的室内空气换热，再经过净化滤芯232过滤可吸入颗粒物等杂质，最后从新风排 风口231排出，其中新风排风口231可以直接连接室内空间，也可以连通至空调器室内机10的换热室110。
本实施例的空调器室内机10可以根据用户的操作指令进入新风模式，也可以根据室内空气的二氧化碳浓度自行进入新风模式。
本实施例的空调器室内机10，包括室内机机壳100以及设置于室内机机壳100内的底部的新风组件200，将新风组件200设置于室内机机壳100内的底部是由于二氧化碳在室内是自下往上积累的，利于将二氧化碳浓度高的室内空气排出去，提高效率，且将新风组件200设置于室内机机壳100内，节省了空间。新风组件200的风口模块210包括风口外壳211，其后板分别形成有用于连通浊风排风管的浊风排风口212、以及用于连通新风进风管的新风进风口213，其侧板开有用于连通室内的浊风进风口214，浊风进风口214至浊风排风口212形成有浊风风道，这种浊风进风口214以及浊风排风口212的设置方式使得室内空气的循环路径增多，使得室内环境的温度变化缓慢，提高用户的温度体验。新风进风口213连接有通向新风组件200外部的新风风道，且浊风风道与新风风道的延伸方向交叉设置，这种设置方式使得空调器室内机10在运行时避免将刚排入室内的新鲜空气排到室外，以提高气体交换的效率。
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。
