在本申请实施例中，如图1至图8所示，该壁挂式空调室内机包括：室内机本体70；新风模块，包括壳体10，所述壳体10设有新风进口11、新风出口12以及连通所述新风进口11与所述新风出口12的新风通道13，所述新风进口11用以与室外连通，所述新风出口12与所述室内机本体70的进风口711连通；风轮80，安装于所述新风通道13；阀门20，安装于所述新风进口11，以打开或关闭所述新风进口11。
在本实施例中，室内机本体70具有进风口711、第一出风口712及连通所述进风口711与第一出风口712的换热风道，新风模块可安装于室内机本体70的一端。新风进口11可开设于壳体10的背面，新风出口12可开设于壳体10的正面，以实现壳体10后侧进风，前侧出风。风轮80的进风侧与新风进口11连通，风轮80的出风侧与新风出口12连通。新风模块工作时，风轮80开启并驱动新风空气从新风进口11进入新风通道13，这部分新风空气先进入风轮80内部，再被沿其径向甩出至新风出口12，最后从新风出口12向外吹出。
阀门20可活动地安装在新风进口11，以控制新风进口11的开关。阀门20的活动方式可为移动，也可为转动，在此不做限制。阀门20的活动可为手动，也可为自动，在此不做限制。在新风模块工作时，阀门20打开新风进口11，以将室外新风通过新风通道13引入室内；在新风模块闲置时，特别是在冬季新风模块使用较少的时候，阀门20关闭新风进口11，以阻挡冷空气进入新风通道13，从而防止新风模块的内部结构被冻坏，提高新风模块的工作寿命。
需要说明，若本申请实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
本申请壁挂式空调室内机通过在新风模块的新风进口11设置阀门20，以通过控制阀门20来控制新风进口11的开关，从而避免新风进口11长期与室外连通，尤其在寒冷季节可避免新风模块的内部结构长期暴露于冷空气中，由此可防止新风模块被冻坏，延长新风模块的使用寿命。
在一实施例中，所述阀门20可转动安装于所述新风进口11，阀门20的转动轴线沿阀门20的长度方向或宽度方向延伸，通过转动的方式来打开或关闭新风进口11，可缩小阀门20的活动轨迹，减少活动所需的占用空间，同时使阀门20的活动更加更加稳定。具体地，如图1和图2所示，所述阀门20包括挡风板21和连接于所述挡风板21侧边的第一转轴22，所述挡风板21通过所述第一转轴22与所述壳体10可转动连接。在本实施例中，新风进口11呈圆孔状设置，挡风板21呈圆板状，第一转轴22沿挡风板21的径向延伸并连接于挡风板21的边缘，新风进口11的孔壁开设有轴孔，第一转轴22与轴孔配合，以实现挡风板21与壳体10的转动连接。
在实际应用中，如图1、图2及图7所示，所述新风模块还包括安装于所述壳体10外的驱动装置30，所述驱动装置30的驱动轴穿过所述壳体10与所述第一转轴22连接，以驱动所述第一转轴22旋转。在本实施例中，驱动装置30可为电机，驱动装置30的驱动轴通过轴孔与第一转轴22连接，从而实现第一转轴22的自动旋转。驱动装置30安装于壳体10外，并可通过固定件连接于壳体10，以减少对壳体10内部空间的占用，从而增大新风通道13的进风量。
在一实施例中，如图1和图2所示，所述阀门20还包括第二转轴23，所述第一转轴22和第二转轴23分别连接于所述挡风板21周缘的相对两侧，所述挡风板21还通过所述第二转轴23与所述壳体10可转动连接。在本实施例中，第一转轴22与第二转轴23共同支撑挡风板21的转动，以分散作用力，提高使用寿命。
具体地，如图2所示，所述壳体10形成有轴槽15，所述轴槽15的槽口设有限位扣50，所述第二转轴23与所述轴槽15可旋转配合，并被所述限位扣50限位于所述轴槽15内。在本实施例中，新风进口11的孔缘朝外延伸呈筒状，轴槽15开设于该筒状的内端面上，轴槽15的槽口背离新风进口11的开口方向，且轴槽15的两相对槽壁与槽口相贯通。轴槽15的槽口设有限位扣50，限位扣50为弹性扣，在安装阀门20时，先将第一转轴22***第一轴孔，接着将第二转轴23挤压限位扣50使其变形至避位槽口，以使第二转轴23能与轴槽15配合，限位扣50再恢复原状以对第二转轴23进行限位。由此，使得阀门20的安装更加简单方便，且实现了阀门20的可拆卸安装，以便对阀门20进行检修更换。
在实际应用中，如图5和图6所示，所述壳体10包括底壳16及盖设于所述底壳16敞口的壳盖17，所述新风进口11及轴槽15开设于所述底壳16，所述第二转轴23的末端凸出于所述轴槽15并套设有轴套，所述壳盖17开设有与所述轴套适配的容置槽。在本实施例中，底壳16敞口的方向与新风进口11的开口方向错开且相互垂直，即底壳16敞口的方向与第二转轴23的延伸方向一致。第二转轴23的末端凸出于轴槽15，且凸出于底壳16的敞口，轴套与第二转轴23可旋转配合，以减少第二转轴23与轴承的摩擦，从而减少第二转轴23及轴槽15的磨损。壳盖17对应轴槽15的位置开设有容置槽，轴套与容置槽固定配合，以实现阀门20与壳盖17的转动连接，从而提高阀门20与壳体10整体的装配强度。
在一实施例中，如图2至图4所示，所述新风模块还包括沿所述进风口711的周向延伸的限位筋40，所述限位筋40两端分别邻近所述第一转轴22及第二转轴23，且所述限位筋40的内周壁凸出于所述新风进口11的孔缘，在所述挡风板21关闭所述进风口711的位置，所述挡风板21的第一板面抵接于所述限位筋40。在本实施例中，限位筋40凸设于壳体10的内壁面，限位筋40呈半圆弧状，且限位筋40的内周壁凸出于新风进口11的孔缘，挡风板21旋转至关闭新风进口11时，挡风板21的内板面有一半的周缘抵接于限位筋40，限位筋40在对挡风板21起到限位停止的作用的同时，还能有效封堵挡风板21与新风进口11的孔缘之间的部分间隙，以提高挡风板21关闭新风进口11的密封性。
具体地，如图2至图4所示，所述新风进口11的孔缘开设有沿周向延伸的限位槽，所述限位槽和限位筋40分别位于所述第一转轴22的两侧，在所述挡风板21关闭所述进风口711的位置，所述挡风板21的第二板面抵接于所述限位槽。在本实施例中，限位槽开设于壳体10的内壁面，限位槽呈半圆弧状，挡风板21关闭新风进口11时，挡风板21的外板面有一半的周缘抵接于限位槽，以提高挡风板21关闭新风进口11的密封性。结合挡风板21与限位筋40的限位抵接，限位筋40和限位槽实现了挡风板21在关闭新风进口11时的错位密封，进一步提高了挡风板21关闭新风进口11的密封性。可以理解，限位筋40和限位槽限定了挡风板21的转动轨迹，即挡风板21只能往复转动。
在实际应用中，所述阀门20的周缘设有密封层；和/或，所述阀门20的表面设置有保温层。在本实施例中，密封层可采用弹性材料制成，如塑胶，以在提高阀门20密封性的同时减少阀门20活动造成的密封层磨损，从而提高密封寿命。保温层可为涂层、棉层或植绒层，保温层可设于阀门20的外表面，以减少冷空气与阀门20的接触，防止阀门20冻损。
需要说明，全文中出现的“和/或”的含义为，包括三个并列的方案，以“A和/或B为例”，包括A方案，或B方案，或A和B同时满足的方案。
在一实施例中，如图5和图6所示，所述新风模块还包括净化组件60，所述净化组件60设置在所述新风通道13内并位于所述风轮80轴向上的一端，以与所述风轮80的进风端对应。
在本实施例中，净化组件60可对进入新风通道13的空气进行过滤净化，以提高进入室内的空气洁净度。风轮80为轴向进风且径向出风，相对于新风进口11处及其附近较窄的进风面而言，在风轮80的进风端形成有更大的进风面，从而在此形成的进风空间也较大。因此，将净化组件60设置为与风轮80的进风端对应，可相应地将净化组件60的供空气通过以实现净化的净化面设计得较大，进而提高净化组件60的净化效率。此外，由于净化组件60设计得较大，因此净化组件60可净化的空气量相应增大，进而还可延长净化组件60的寿命，以延长更换净化组件60的周期。
具体地，如图5至图7所示，所述壳体10的前侧壁开设有所述新风出口12，并在所述新风出口12的一侧开设有安装口，所述净化组件60自所述安装口可抽拉地安装于所述壳体10。在本实施例中，净化组件60包括安装架及安装于安装架上的净化件。净化件可适用于去除空气中的粉尘、细微粒物、微生物、有机挥发性气体（如甲醛等）等空气污染物中任意一种或多种。净化件的具体类型可依据其功能进行选取，净化件可以是普通过滤网或HEPA网或除甲醛器或IFD过滤器中任意一种或两种组合；还可以是初效过滤网、中效过滤网、高效过滤网中任意一种或多种组合。
安装口呈长条形设置，并与新风出风的一侧边同向延伸。通过将净化组件60自安装口可抽拉地安装于新风通道13，可使得净化组件60具有安装在新风通道13的工作状态，以及从安装口向外侧抽出的闲置状态。净化组件60在工作状态下，可对新风通道13的气流进行净化，去除空气中的污染物；净化组件60在闲置状态下，用户可对净化组件60进行清洁或更换。用户通过手持拉动净化组件60，即可自行切换净化组件60的状态。此外，新风模块的新风出口12通常朝向用户所在区域，通过将抽拉净化组件60的安装口设置在新风出口12的一侧，也就是将安装口朝向用户所在区域，这样可以方便用户从前侧抽拉净化组件60，以切换净化组件60的状态。
在一实施例中，如图5和图6所示，所述净化组件60将所述新风通道13分隔为与所述新风进口11连通的进风腔131，以及与所述新风出口12连通的出风腔132，所述风轮80安装于所述出风腔132。在本实施例中，风轮80为离心风轮80，风轮80的进风侧与净化组件60对应，风轮80背离进风侧的一端与驱动电机连接，以通过驱动电机驱动风轮80旋转。空气从新风进口11进入进风腔131，经净化组件60净化处理成洁净的新风，而后进入风轮80内部，最后被离心风轮80朝新风出口12吹出。
具体地，如图5和图6所示，所述壳体10包括底壳16及盖设于所述底壳16敞口的壳盖17，所述底壳16形成有相隔的第一腔体161和第二腔体162，所述第一腔体161形成所述出风腔132，所述第二腔体162位于所述第一风轮80的周侧，且所述新风进口11开设于所述第二腔体162的腔壁；所述净化组件60设于所述第一腔体161的敞口处，以与所述壳盖17之间形成第三腔体171，所述第三腔体171与所述第二腔体162连通形成所述进风腔131。
在本实施例中，新风空气从新风进口11进入第一腔体161后，先流至第三腔体171，流经净化组件60后再流至第三腔体171，最后从新风出口12吹出。如此，新风进口11和新风出口12均可位于风轮80的周侧，从而可简化壳体10的外部形状，缩小占用空间，以方便新风模块与室内机本体70的装配。
需要说明，若本申请实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。
在实际应用中，机壳71包括底盘72、面框73及面板74；新风模块安装于底盘72的端部，新风模块的新风出口12朝向面板74开放；相应地，面板74在对应新风出口12的位置开设有第二出风口713，以使得室内机本体70向前送出新风空气，使得新风空气准确到达用户所在方位。此外，为避免新风直吹用户，可选将第二出风口713由贯设于面板74上的多个微孔组成，以在新风空气从多个微孔吹出后，气流被打散成一缕缕较小的细丝气流，风速降低，气流变得柔和，不会直接吹向用户，避免用户产生不适感。
本申请还提出一种空调器，该空调器包括一种壁挂式空调室内机，该壁挂式空调室内机的具体结构参照上述实施例，由于本空调器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
