具体实施方式
下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本公开的实施例。
下面参考图1-图18描述根据本公开实施例的空调室内机100，该空调室内机100可以用于调节室内的空气温度和空气湿度。
如图1所示，根据本公开实施例的空调室内机100，包括：壳体1、内导风板2、外导风板3和风道组件4。
其中，如图2-图5所示，壳体1可以包括具有第一容纳空间的第一容纳部11和具有第二容纳空间的第二容纳部12，第一容纳部11可以具有出风口16，第二容纳空间可以位于第一容纳空间的前侧，内导风板2可以通过第一枢转轴5可枢转地设在第一容纳空间内，外导风板3可以通过第二枢转轴6可枢转地设在第二容纳空间内。内导风板2和外导风板3可以通过与壳体1之间的相对转动以调节出风口16的出风方向，由此可以实现不同的送风状态，满足用户不同的使用需求。
如图1-图2所示，风道组件4可以设在壳体1内，风道组件4可以包括第一侧壁41和位于第一侧壁41下方的第二侧壁42，第一侧壁41与第二侧壁42之间可以限定出与出风口16连通的风道43，第一枢转轴5可以邻近第一侧壁41设置，第二枢转轴6可以邻近第二侧壁42设置，第一侧壁41的面向第二侧壁42的一侧表面(如图2和图3所示的下表面)为第一风道面411，第二侧壁42的面向第一侧壁41的一侧表面(如图4和图5所示的上表面)为第二风道面421。其中，需要进行说明的是，上述描述中的“上”是指第一侧壁41的靠近的天花板的一侧侧壁，上述描述中的“下”是指第一侧壁41的靠近地板的一侧侧壁。
如图2-图3所示，第一侧壁41的面向出风口16的一端(如图2所示的前端)可以设有过渡部44，过渡部44的面向第二侧壁42的一侧表面(如图3所示的下表面)为过渡面441，沿朝向出风口16的方向、过渡面441可以相对于第一风道面411倾斜向下延伸。例如，如图3所示，沿从后往前的方向，过渡面441可以相对于第一风道面411斜向下延伸。由此，通过上述设置，过渡面441可以对气流起到引导的作用，过渡面441可以引导气流斜向下流通，从而可以有效防止气流进入到第一枢转轴5与壳体1之间的空隙内，从而可以防止在内导风板2和壳体1上形成凝露。
需要进行说明的是，上述描述中的“前”是指空调室内机100远离墙壁的一侧，上述描述中的“后”是指空调室内机100靠近墙壁的一侧。
根据本公开实施例的空调室内机100，通过在风道组件4的第一侧壁41的面向出风口16的一端设置过渡部44，过渡部44可以对气流起到引导的作用，过渡部44可以引导气流斜向下流通，从而可以有效防止气流进入到第一枢转轴5与壳体1之间的空隙内，可以防止在内导风板2和壳体1上形成凝露。
根据本公开的一些实施例，第一枢转轴5可以位于第一侧壁41的远离第二侧壁42的一侧， 例如，如图2所示，第一枢转轴5可以位于第一侧壁41的上方，由此可以使第一枢转轴5避让风道43的出风路径，从而可以减小气流的流通阻力、降低空调室内机100的工作噪声。
如图2所示，在本公开的一些实施例中，当内导风板2位于打开出风口16的打开位置时，内导风板2的面向第二侧壁42的一侧表面(如图2所示的下表面)适于与第一风道面411大致平齐，由此内导风板2的下表面与第一风道面411可以大致组成为一个导风面，从而可以有效延长空调室内机100的送风距离，进而可以提升空调室内机100的制冷和制热效率。
如图4-图5所示，根据本公开的一些实施例，第二侧壁42的前端可以具有外导风板安装部422，外导风板安装部422的上端可以位于外导风板安装部422的下端的前侧(如图4所示的L 1＞L 2)，第二枢转轴6可以设在外导风板安装部422处，由此，外导风板安装部422的靠近风道43的一侧表面可以引导气流通过出风口16排出，从而可以防止气流进入到第二枢转轴6与壳体1之间的空隙内，可以防止外导风板3与壳体1上形成凝露。
如图5所示，在本公开的一些实施例中，第二风道面421的至少邻近第二枢转轴6的部分形成为凹面，由此，可以根据“康达效应”，气流可以沿着第二风道面421的延伸方向流通，从而可以确保气流朝向远离第二枢转轴6与壳体1之间的间隙的方向流通，使得气流不会进入到第二枢转轴6与壳体1之间的间隙内。当然可以理解的是，也可以将第二风道面421整体设置成凹面，根据“康达效应”，空气气流在出风口16处可以斜向上流通，从而可以有效防止在外导风板3与壳体1上形成凝露。
如图2所示，在本公开的一些实施例中，当外导风板3位于打开出风口16的打开位置时，外导风板3的面向第一侧壁41的一侧表面(如图2所示的上表面)适于与第二风道面421大致平齐，由此外导风板3的上表面与第二风道面421可以大致形成为一个导风面，从而可以有效延长空调室内机100的送风距离，进而可以提升空调室内机100的制冷和制热效率。
如图3和图5所示，根据本公开的一些实施例，第一枢转轴5与第一容纳空间的内壁之间可以具有第一间隙14，第二枢转轴6与第二容纳空间的内壁之间可以具有第二间隙15，第一间隙14和第二间隙15可以确保第一枢转轴5和第二枢转轴6与壳体1之间能够进行顺畅地相对转动。其中，如图9-图10所示，第一间隙14和第二间隙15中的至少一个内设有密封条7。也就是说，可以在第一间隙14内设置密封条7，也可以在第二间隙15内设置密封条7，还可以同时在第一间隙14和第二间隙15内设置密封条7。密封条7可以对第一间隙14和/或第二间隙15进行密封，从而可以防止气流进入到第一间隙14和第二间隙15内，进而可以防止壳体1、内导风板2和外导风板3上形成凝露。
根据本公开的一些实施例，密封条7可以包括第一密封条71，第一密封条71可以粘贴至壳体1。例如，可以在壳体1上设置粘结面，第一密封条71可以通过粘结面粘接在壳体1上。由此，通过上述设置，可以使密封条7的装配方式更加简单，进而可以提升密封条7的装配效率。
如图16-图18所示，在本公开的一些实施例中，第一密封条71包括粘接部711和密封部 712，粘接部711可以粘接在壳体1上，密封部712的一端可以与粘接部711相连，密封部712的另一端可以延伸至第一间隙14和第二间隙15中的至少一个内，由此，通过上述设置，可以使第一密封条71的结构设计更加简单，从而可以减小第一密封条71的模具的加工难度，提高生产效率。例如，在图15所示的具体示例中，粘接部711和密封部712均形成为平板状，第一密封条71可以大致呈L形，由此可以使第一密封条71的整体结构更加简单、减小模具的加工难度。
如图9-图11所示，在本公开的一些实施例中，密封条7还可以包括第二密封条72，第二密封条72可以与壳体1卡扣连接，由此可以方便第二密封条72的安装和拆卸，从而可以方便第二密封条72的检修和更换。
如图11和图14所示，在本公开的一些实施例中，壳体1上可以形成有间隔设置的多个卡槽13，第二密封条72的宽度方向(如图14所示的前后方向)上的一侧可以设有多个卡扣721，多个卡扣721可以分别配合在多个卡槽13内，第二密封条72的宽度方向(如图14所示的前后方向)上的另一侧可以延伸至第一间隙14和第二间隙15中的至少一个内。由此，通过上述设置，第二密封条72与壳体1之间可以形成多点连接，从而可以提升第二密封条72与壳体1之间的配合牢固性。需要进行说明的是，上述描述中的“后”是指空调室内机100的靠近墙壁的一侧。
如图14所示，在本公开的一些实施例中，多个卡扣721可以包括多个第一卡扣7211和多个第二卡扣7212，多个第一卡扣7211可以沿第二密封条72的长度方向(如图14所示的左右方向)间隔设置，每个第一卡扣7211可以具有第一卡口部7211a，多个第二卡扣7212可以沿第二密封条72的长度(如图14所示的左右方向)方向间隔设置，多个第二卡扣7212与多个第一卡扣7211交错布置，每个第二卡扣7212可以具有第二卡口部7212a，第二卡口部7212a与第一卡口部7211a的朝向相反。当第二密封条72与壳体1进行配合时，第一卡口部7211a和第二卡口部7212a可以分别钩设在壳体1上，由此可以将第二密封条72牢固地固定在壳体1上。需要进行说明的是，上述描述中的“左右”是指用户面对空调室内机100的前侧时其左手和右手的方向。
如图14所示，在本公开的一个具体示例中，第二密封条72包括本体723和多个卡扣721，多个卡扣721包括多个第一卡扣7211和多个第二卡扣7212且位于本体723的前端，多个第一卡扣7211沿本体723的长度方向均匀间隔设置，多个第二卡扣7212沿本体723的长度方向均匀间隔设置，多个第一卡扣7211和多个第二卡扣7212沿本体723的长度方向均匀交错设置，壳体1上设有与多个第一卡扣7211和多个第二卡扣7212一一对应的卡槽13。其中，每个第一卡扣7211的前端设有第一卡扣部7211a，第一卡扣部7211a朝上设置，第一卡扣部7211a上设有第一导向面，沿从后往前的方向第一导向面斜向下延伸，第一导向面可以引导第一卡扣7211进入到对应的卡槽13内。每个第二卡扣7212的前端设有第二卡扣部7212a，第二卡扣部7212a朝下设置，第二卡扣部7212a上设有第二导向面，沿从后往前的方向第二导 向面斜向上延伸，第二导向面可以引导第二卡扣7212进入到对应的卡槽13内。由此，通过上述设置，可以使第二密封条72的结构设置更加合理，不仅方便第二密封条72的安装和拆卸，还可以提升第二密封条72与壳体1之间的装配牢固性。
如图13所示，在本公开的一些实施例中，第二密封条72上可以设有限位部722，限位部722可以从第二密封条72的厚度方向(如图13所示的上下方向)上的两侧向外延伸，限位部722可以对第二密封条72起到限位的作用，从而可以防止第二密封条72从壳体1上脱落，可以确保第二密封条72的密封效果。
在本公开的一些可选的实施例中，第一间隙14和第二间隙15内均可以设有密封条7，由此可以起到更好的密封效果，可以有效防止内导风板2、外导风板3和壳体1上形成凝露。
可选地，密封条7可以为弹性密封条，弹性密封条具有较好的柔韧性，不仅可以满足内导风板2和外导风板3的正常转动，还可以具有良好的密封效果。例如，弹性密封条可以为橡胶材料件，弹性密封条还可以为硅胶材料件。
下面参考附图详细描述根据本公开实施例的空调室内机100具有的多种不同的送风状态。
如图2所示，内导风板2的下表面可以形成为凸面，外导风板3的上表面可以形成为凹面。空调室内机100可以具有沐浴风风板状态，此时内导风板2转动至适于与第一风道面411平齐的位置、外导风板3转动至与水平平面大致平齐的位置，根据“康达效应”，内导风板2和外导风板3可以引导气流斜向上流通。由于冷风的空气密度较大，在重力的作用下，冷风在室内空间内至上而下流通，形成沐浴风的吹风效果，从而可以防止冷风直接吹向用户，提升用户的使用舒适度。
如图4所示，空调室内机100可以具有最大风风板状态。其中，当室内温度与用户所需温度之间的温差较大时，可以将空调室内机100调节至最大风风板状态。此时内导风板2可以逆时针旋转至其下表面与第一风道面411平齐的位置，外导风板3顺时针旋转至其上表面与第二风道面421平齐的位置，此时出风口16的出风面积最大，空调室内机100的单位时间内的送风量也最大，从而可以提升空调室内机100的制冷和制热效率。
如图6所示，空调室内机100可以具有地毯风风板状态。其中，当空调室内机100处于制热状态时，由于热风的空气密度较小，热风很难吹到室内的地板上，此时可以将空调室内机100调节至地毯风风板状态。当空调室内机100处于地毯风风板状态时，内导风板2和外导风板3均旋转至竖直延伸的位置，此时内导风板2和外导风板3可以引导热风竖直向下流通，进而可以确保热风顺利地流通至地板上，可以对用户起到暖足的效果。
如图7所示，空调室内机100可以具有第一摆动送风状态。当空调室内机100处于第一摆动送风状态时，内导风板2转动至其下表面与第一风道面411平齐的位置并保持静止，外导风板3相对壳体1转动。其中，当空调室内机100处于制冷模式时，可以将空调室内机100调节至第一摆动送风状态，由此可以引导冷风在室内空间内先至下而上流通，然后冷风在重力的作用下至上而下缓慢流通，不仅可以防止冷风直接吹向用户，还可以提升室内的温度均 匀性。
如图8所示，空调室内机100可以具有第二摆动送风状态。当空调室内机100处于第二摆动送风状态时，外导风板3转动至竖直延向下的位置并保持静止，内导风板2相对壳体1转动。其中，当空调室内机100处于制热模式时，可以将空调室内机100调节至第二摆动送风状态，由此可以引导热风在室内空间内至上而下流通，可以确保热风顺利地流通至地板上，可以提升室内的温度均匀性。
如图1所示，当空调室内机100停止使用时，内导风板2和外导风板3可以分别转动至与壳体1相配合的位置以关闭出风口16。
下面参考附图以三个具体实施例详细描述根据本公开的空调室内机100。值得理解的是，下面描述仅是示例性的，而不是对本公开的具体限制。
实施例一：
如图1所示，根据本公开实施例的空调室内机100，包括：壳体1、内导风板2、外导风板3、风道组件4、风机8和换热器9。
其中，风机8和换热器9均设在壳体1内，壳体1上设有与换热器9正对设置的进风口。壳体1包括具有第一容纳空间的第一容纳部11和具有第二容纳空间的第二容纳部12，第一容纳部11具有出风口16，第二容纳空间位于第一容纳空间的前侧。内导风板2通过第一枢转轴5可枢转地设在第一容纳空间内，外导风板3通过第二枢转轴6可枢转地设在第二容纳空间内。
如图2-图3所示，风道组件4设在壳体1内，风道组件4包括第一侧壁41和位于第一侧壁41下方的第二侧壁42，第一侧壁41与第二侧壁42之间可以限定出与出风口16连通的风道43，第一枢转轴5可以邻近第一侧壁41设置，第二枢转轴6可以邻近第二侧壁42设置，第一侧壁41的面向第二侧壁42的一侧表面(如图2所示的下表面)为第一风道面411，第二侧壁42的面向第一侧壁41的一侧表面(如图2所示的上表面)为第二风道面421。
第一侧壁41的面向出风口16的一端(如图2所示的前端)设有过渡部44，过渡部44的面向第二侧壁42的一侧表面(如图3所示的下表面)为过渡面441，沿朝向出风口16的方向、过渡面441可以相对于第一风道面411倾斜向下延伸。由此，通过上述设置，过渡面441可以对气流起到引导的作用，过渡面441可以引导气流斜向下流通，从而可以有效防止气流进入到第一枢转轴5与壳体1之间的空隙内，从而可以防止在内导风板2和壳体1上形成凝露。
实施例二：
如图4-图5所示，与实施例一不同的是，实施例二中的空调室内机100的第二侧壁42的前端具有外导风板安装部422，外导风板安装部422的上端可以位于外导风板安装部422的下端的前侧(如图4所示的L 1＞L 2)，第二枢转轴6可以设在外导风板安装部422处。而且，第二风道面421的至少邻近第二枢转轴6的部分形成为凹面，由此，可以根据“康达效应”，气流可以沿着第二风道面421的延伸方向流通，从而可以确保气流朝向远离第二枢转轴6与壳体1之间的间隙，使气流不会进入到第二枢转轴6与壳体1之间的间隙内，从而可以有效 防止外导风板3与壳体1上形成凝露。
实施例三：
如图16-图18所示，与实施例一不同的是，实施例三中的空调室内机100的第一枢转轴5与第一容纳空间的内壁之间具有第一间隙14，第二枢转轴6与第二容纳空间的内壁之间具有第二间隙15，第一间隙14和第二间隙15中的至少一个内设有密封条7。
其中，密封条7可以包括第一密封条71，第一密封条71包括粘接部711和密封部712，粘接部711可以粘接在壳体1上，密封部712的一端可以与粘接部711相连，密封部712的另一端可以延伸至第一间隙14和第二间隙15中的至少一个内。
如图9-图11所示，密封条7还可以包括第二密封条72，第二密封条72可以与壳体1卡扣连接。其中，第二密封条72包括本体723和多个卡扣721，多个卡扣721包括多个第一卡扣7211和多个第二卡扣7212且位于本体723的前端，多个第一卡扣7211沿本体723的长度方向均匀间隔设置，多个第二卡扣7212沿本体723的长度方向均匀间隔设置，多个第一卡扣7211和多个第二卡扣7212沿本体723的长度方向均匀交错设置，壳体1上设有与多个第一卡扣7211和多个第二卡扣7212一一对应的卡槽13。其中，每个第一卡扣7211的前端设有第一卡扣部7211a，第一卡扣部7211a朝上设置，第一卡扣部7211a上设有第一导向面，沿从后往前的方向第一导向面斜向下延伸，第一导向面可以引导第一卡扣7211进入到对应的卡槽13内。每个第二卡扣7212的前端设有第二卡扣部7212a，第二卡扣部7212a朝下设置，第二卡扣部7212a上设有第二导向面，沿从后往前的方向第二导向面斜向上延伸，第二导向面可以引导第二卡扣7212进入到对应的卡槽13内。
由此，通过上述设置，密封条7可以对第一间隙14和/或第二间隙15进行密封，从而可以防止气流进入到第一间隙14和第二间隙15内，进而可以防止壳体1、内导风板2和外导风板3上形成凝露。
