具体实施方式
下面详细描述本申请的实施例，所述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，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图9描述根据本申请实施例的空调室内机100，空调室内机100可以用于调节室内环境的温度，例如，空调室内机100可以为挂机或柜机。
参照图1-图9所示，空调室内机100为壁挂式空调室内机，空调室内机100可以包括壳体1、接水盘7、导风板5、开关门2、清扫条3和导风板电机(图未示出)，壳体1具有出风口12，导风板5可转动地设在出风口12处，导风板5上设有微孔511，导风板电机用于驱动导风板5转动。
开关门2可移动地设在壳体1的前侧以打开或关闭出风口12，清扫条3设在开关门2上，清扫条3可用于扫除导风板5的冷凝水和/或灰尘，接水盘7设在出风口12的底部以用于接收导风板5的冷凝水，在无风感模式导风板5在接水盘7的正投影位于接水盘7内(例如，如图1所示，在由上向下的方向上、导风板5在接水盘7的投影为导风板5在接水盘7的正投影)，同时，参照图2所示，导风板5在接水盘7的正投影位于接水盘7内时导风板5的最大转动角度为α 0。
需要说明的是，当用户正对空调室内机100时，用户的头顶方向为上，用户的脚底方向为下，用户的左边为左，用户的右边为右，靠近用户胸前的方向为前，远离用户的胸腔的方向为后。
例如，如图1和图6所示，壳体1的出风口12在上下方向上延伸且形成为长条状，导风板5包括多个子导风板51，多个子导风板51彼此间隔开地设在出风口12处，每个子导风板51形成为长条形且导风板5的旋转中心线在竖直方向上延伸，每个子导风板51上设有多个微孔511，多个微孔511在子导风板51的厚度方向上贯穿子导风板51。
具体地，如图1和图7所示，空调室内机100还包括室内换热器6、风道11、风轮和用于驱动开关门2左右移动的驱动装置4，风轮设在风道11内。其中，空调室内机100可实现无风感送风，当空调室内机100进行无风感送风时，导风板5关闭出风口12，从而让风道11内集中的气流疏散成众多细微的气丝排向室内空间，有利于提高用户的 舒适度，接水盘7设在出风口12的底部以用于接收导风板5的冷凝水。
进一步地，如图7所示，开关门2可移动地设在壳体1的前侧以打开或关闭出风口12，清扫条3设在开关门2上且可用于扫除导风板5的冷凝水，开关门2和清扫条3分别为两个且一一对应，两个开关门2在左右方向上间隔开设置，清扫条3可将导风板5上的冷凝水的扫刮到接水盘7内。
如图7和图8所示，每个开关门2的后表面上设有加强筋21，每个开关门2的加强筋21上设有卡槽211，每个加强筋21的卡槽211的开口端的相对内侧壁上分别设有朝向靠近彼此的方向延伸的翻边212，每个清扫条3的前端设有与相应的卡槽211配合的扣合部31，扣合部31上设有与翻边212配合的台阶面311，每个清扫条3的后端向后延伸，其中，清扫条3为柔性件，例如，清扫条3可以为橡胶件或硅胶件，当开关门2在驱动装置4的作用下关闭出风口12或者打开出风口12时、清扫条3与导风板5接触以将导风板5上的冷凝水扫刮到接水盘7内。可以理解的是，开关门2、导风板5与空调室内机100的控制装置有信号的传递，空调室内机100的控制装置可以分别控制开关门2以及导风板5的打开或关闭。
发明人在实际研究中发现，由于接水盘7结构上的限制，在无风感模式、导风板5关闭出风口12，导风板5在接水盘7的正投影位于接水盘7内，导风板5前表面上的冷凝水可顺着导风板5向下流动到接水盘7内；但当导风板5打开出风口12时以向室内送风(例如，如图2所示)时，导风板5在接水盘7的正投影会超出接水盘7，也就是说，导风板5的部分会超出接水盘7的接收范围，导致导风板5上的部分冷凝水滴落到地面。
对此，发明人创造性地提出，在空调室内机100退出无风感工作模式前，可先利用开关门2上的清扫条3以将导风板5上的冷凝水扫刮到接水盘7内，从而当导风板5打开出风口12以向室内送风时，导风板5上不会有冷凝水滴落到地面上。
具体而言，当空调室内机100正常工作(例如制冷)时，如图3所示，两个开关门2朝向远离彼此的方向移动至打开出风口12的位置，接着导风板5部分打开出风口12，在风轮的作用下，与室内换热器6换热后的空气可由风道11排向出风口12，并通过出风口12流入室内空间以调节室内环境的温度。当用户需要开启空调室内机100的无风感模式时，空调室内机100的控制方法可以包括如下步骤：S10：空调室内机100开启无风感模式；S20：在空调室内机100接收到退出无风感模式的指令时，控制开关门2在关闭出风口12和打开出风口12之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，且在此过程中清扫条3与导风板5接触以将导风板5上的冷凝水扫刮 到接水盘7内；S30：退出无风感模式。
参照图10所示，根据本申请实施例的空调室内机100的控制方法，可以包括如下步骤：
S10：空调室内机100开启无风感模式。例如，与空调室内机100匹配的遥控器上可以设有无风感模式键，用户可按下无风感模式键以开启无风感模式。
S20：在空调室内机100接收到退出无风感模式的指令时，控制开关门2在关闭出风口12和打开出风口12(开关门2从图1位置移动到图3位置后又移动到图1位置)之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，其中，n＞0。可以理解的是，空调室内机100接收到退出无风感模式的指令，可以有以下两种形式：例如，与空调室内机100匹配的遥控器上可以设有无风感退出键，用户可按下无风感退出键以发出退出无风感模式的指令，空调室内机100接收到退出无风感模式的指令以进行步骤S20；又如，空调室内机100控制装置可根据室内环境温度、室内环境湿度或者无风感模式的工作时间来判断是否向空调室内机100发送退出无风感模式的指令，当环境温度、室内环境湿度或者无风感模式的工作时间达到预设值时，控制装置发出退出无风感模式的指令，空调室内机100接收到退出无风感模式的指令以进行步骤S20。
S30：退出无风感模式。例如，在开关门2到达打开出风口12的位置时、导风板5至少部分打开出风口12以向室内环境送风，空调室内机100即退出无风感模式。
由此，通过在空调室内机100接收到退出无风感模式的指令时，控制开关门2在关闭出风口12和打开出风口12之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，从而可在不牺牲空调器的制冷能力的基础上，实现空调室内机100的无风感出风，且避免导风板5上的冷凝水滴落到地面上。
根据本申请实施例的空调室内机100的控制方法，通过在空调室内机100接收到退出无风感模式的指令时，控制开关门2在关闭出风口12和打开出风口12之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，由此，可在不牺牲空调器的制冷能力的基础上，实现空调室内机100的无风感出风，且避免导风板5上的冷凝水滴落到地面上。
在本申请的一些实施例中，如图10所示，n满足：1≤n≤3。由此，一方面通过使得开关门2在关闭出风口12和打开出风口12之间往返移动的次数n不至于过少，从而避免清扫条3扫除导风板5表面的冷凝水的效果差；另一方面通过使得开关门2在关闭出风口12和打开出风口12之间往返移动的次数n不至于过多，从而避免时间和能量的浪费。例如，n可以为1、2或3。
在本申请的一些实施例中，如图11所示，所述步骤S20包括：
S21：在所述空调室内机100接收到退出无风感模式的指令时，控制导风板电机产生电机堵转；
S22：控制开关门2在关闭出风口12和打开出风口12之间往返(例如开关门2从图1中位置移动到图4中位置、接着移动到图1中位置)移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水。
可以理解的是，首先在步骤S21，在空调室内机100接收到退出无风感模式的指令时，控制导风板电机堵转以带动导风板5振动，以使得导风板5上的冷凝水在导风板5的振动作用以及冷凝水的重力作用下滑落到接水盘7内，接着在步骤S22，控制开关门2在关闭出风口12和打开出风口12之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，由此，有利于在空调室内机100退出无风感模式时、完全扫除导风板5表面的冷凝水，进而避免导风板5上的冷凝水滴落到地面上，进而提高用户的使用体验。
在本申请的一些实施例中，如图12所示，所述步骤S20包括：
S21：在空调室内机100接收到退出无风感模式的指令时退出无风感模式且控制导风板5在α 1与α 2之间来回转动m次，其中，0°≤α 1＜α 2≤α 0；
可以理解的是，空调室内机100接收到退出无风感模式的指令，可以有以下两种形式：例如，与空调室内机100匹配的遥控器上可以设有无风感退出键，用户可按下无风感退出键以发出退出无风感模式制冷的指令，空调室内机100接收到退出无风感模式的指令以进行步骤S21以及后续的步骤S22；又如，空调室内机100控制装置可根据室内环境温度、室内环境湿度或者无风感模式的工作时间来判断是否向空调室内机100发送退出无风感模式的指令，当环境温度、室内环境湿度或者无风感模式的工作时间达到预设值时、发出退出无风感模式制冷的指令，空调室内机100接收到退出无风感模式的指令以进行步骤S21以及后续的步骤S22。
S22：进入无风感模式且控制开关门2在关闭出风口12和打开出风口12之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，且在此过程中清扫条3与导风板5接触以将导风板5上的冷凝水扫刮到接水盘7内。
可以理解的是，在步骤S21，空调室内机100接收到退出无风感模式，控制导风板5在α 1与α 2之间来回转动m次、以使得导风板5上的冷凝水在导风板5的转速产生的动力以及冷凝水的重力作用下滑落到接水盘7内；在步骤S22，进入无风感模式，也就是说使得导风板5关闭出风口12，接着控制开关门2在关闭出风口12和打开出风口12 之间往返移动n次以带动清扫条3移动以扫除导风板5表面的冷凝水，由此，可在不牺牲空调器的制冷能力的基础上，可实现空调室内机100的无风感出风，且有利于在空调室内机100退出无风感模式时、完全扫除导风板5表面的冷凝水，进而避免导风板5上的冷凝水滴落到地面上，进而提高用户的使用体验。
在本申请的一些实施例中，参照图12所示，m满足：2≤m≤5。由此，一方面使得导风板5在α 1与α 2之间来回转动的次数m不至于过少，从而避免在步骤上S20，在导风板5的转速产生的动力以及冷凝水的重力作用下滑落到接水盘7内的冷凝水过少；另一方面，使得导风板5在α 1与α 2之间来回转动的次数m不至于过多，从而避免时间和能量的浪费。例如，m可以为二、三、四或五。
在本申请的一些实施例中，参照图12所示，α 0满足：α 0≤20°。由此，导风板5在接水盘7的正投影完全位于接水盘7内，可使得导风板5在α 1与α 2之间来回转动时，从导风板5表面上滑落的冷凝水可完全落入接水盘7内，从而防止导风板5在α 1与α 2之间来回转动时、导风板5上的冷凝水滴落到地面上。例如，α 0可以为5°、10°、15°或20°。
在本申请的一些实施例中，参照图12所示，α 1＝0°，α 2＝α 0。由此，使得在步骤S20时导风板5来回转动的角度最大，有利于使得冷凝水在导风板5的转速产生的动力以及冷凝水的重力作用下滑落到接水盘7内。
在本申请的一些实施例中，参照图12所示，α 1满足：0°≤α 1≤5°。由此，有利于保证在步骤S20时、导风板来回转动的角度较大，从而有利于使得冷凝水在导风板5的转速产生的动力以及冷凝水的重力作用下滑落到接水盘7内。例如，α 1可以为0°、1°、2°、3°、4°或5°。
如图13所示，根据本申请实施例的空调室内机的控制方法，可以包括如下步骤：
A10：开启导风板5清洁功能。例如，与空调室内机100匹配的遥控器上可以设有清洁功能按键，用户可按下清洁功能按键以开启导风板5的清洁功能。
A20：控制导风板5转动至关闭出风口12(如图1所示导风板所在的位置)。
A30：控制开关门2移动以带动清扫条3移动以扫除导风板5表面的灰尘。例如，当空调室内机100处于开机状态时，此时开关门2打开出风口12，可控制开关门2朝向关闭出风口12的方向移动后再朝向打开出风口12的方向移动(开关门从图1位置移动到图4位置后又移动到图1位置)以带动清扫条3移动以扫除导风板5表面的灰尘。又如，当空调室内机100处于关机状态时，此时开关门2关闭出风口，可控制开关门2朝向打开出风口12的方向移动(开关门2可从图4位置移动到图1位置)以带动清扫条3 移动以扫除导风板5表面的灰尘。
A40：退出导风板5清洁功能。由此，通过控制开关门2移动以控制清扫条3移动就可以实现扫除导风板5表面的灰尘，可避免在给导风板5除尘时拆卸空调室内机100，且不必对导风板5进行人工除尘，有利于提高用户的使用体验。
根据本申请实施例的空调室内机100的控制方法，通过控制开关门2移动以带动清扫条3移动以扫除导风板5表面的灰尘，可避免在给导风板5除尘时拆卸空调室内机100，且不必对导风板5进行人工除尘，有利于提高用户的使用体验。
在本申请的一些实施例中，如图14所示，在步骤A10和步骤A20之间还包括步骤：A11：控制导风板5转动至预设角度λ(例如，如图2所示的导风板5转动至的角度)以部分打开出风口12且控制风轮的转速增大F r/min，其中，F＞0，预设角度λ可以理解为由导风板5关闭出风口12的位置转动到导风板5打开出风口12的位置、导风板5所转过的角度。由此，通过提高风轮的转速，有利于提高风道11内气流的流速，从而在气流从风道11流向出风口12的过程中、有利于气流将导风板5上附着的部分灰尘吹走，有利于提高除尘的效果，并且可减小在A30步骤时清扫条3所要清理的灰尘量，进而可提高清扫条3的使用寿命。
可选地，如图14所示，在步骤A11和步骤A20之间，控制方法还包括：A12：t min后，控制风轮的转速降低X r/min，X≥F，t＞0。可以理解的是，在步骤A11之后的步骤A20需要控制导风板5转动至关闭出风口12，为保证在步骤A20空调室内机100工作的安全性，需要提前降低风轮的转速，因此通过增加步骤A11，有利于避免在步骤A20时使得空调室内机100内风压过大，从而有利于提高导风板5转动至关闭出风口12的过程中的安全性。
在本申请的一些可选的实施例中，参照图14所示，在A12中，t min后，控制风轮的转速降低至最低转速。可以理解的是，在步骤A30(清扫条3移动以扫除所述导风板5表面的灰尘)，而通过提前控制风轮的转速降低至最低转速，有利于减小在步骤A30时、从风道11内吹出的气流将清扫条3清除下的灰尘吹到用户身上。当然，本申请不限于此，也可以是在A12中，t min后，控制风轮的转速降低至零，也就是说，在A12中，t min后，风道11内的没有气流流向室内空间，从而可避免从风道11内吹出的气流将清扫条3清除下的灰尘吹到用户身上。
可选地，参照图14所示，5≤t≤25。由此，一方面使得从风道11内吹出的气流吹向导风板5的时间t不至于过短，从而有利于保证在A11步骤时、气流对导风板5上的灰尘的清理的效果，另一方面使得，另一方面使得t不至于过大，可避免造成电能的浪费， 从而有利于节省成本。例如，t可以为5、10、15、20或25，其中，关于t的具体数值可根据空调室内机100的具体规格型号调整设计。
在本申请的一些可选的实施例中，参照图14所示，25≤F≤70。由此，一方面使得在步骤A11时、风轮增加的转速F r/min不至于过小，从而有利于增强从风道11流向出风口12的气流、对导风板5上附着的部分灰尘的清理效果，另一方面使得在步骤A11时、风轮增加的转速F r/min不至于过大，从而有利于使得空调室内机100的能量损耗不至于过大，有利于保证空调室内机100的运行成本。例如，F可以为25、35、45、55或70，关于F的具体数值可根据空调室内机100的具体规格型号调整设计。
可选地，45°≤λ≤90°。由此，有利于保证空调室内机100在步骤A11时的出风量，进而有利于保证从风道11流向出风口12的气流、可将导风板5上附着的部分灰尘吹走。
在本申请的一些可选的实施例中，参照图14所示，在步骤A30中，控制开关门2在打开出风口12和关闭出风口12之间往返k次，k＞0。可以理解的是，在步骤A30，在开关门2打开出风口12和关闭出风口12之间往返k次的过程中，清扫条3随之往返运动k次以扫除导风板5表面的灰尘，从而有利于提高对导风板5的清洁效果，并且不影响空调室内机100的下一步工作。例如，开关门2在打开出风口12和关闭出风口12之间往返的次数默认为一次，并且用户还可设定开关门2在打开出风口12和关闭出风口12之间往返的次数k，例如，k可被设定为二、三、四或五等，由此用户可对清扫条3的除尘次数进行个性化设定，增强了空调室内机100的科技感，有利于提高用户使用体验。
在本申请的一些实施例中，在接收到打开空调室内机100的指令后，开启导风板5清洁功能。由此，在打开空调室内机100时，就可以实现对导风板5的除尘，从而不必用户刻意去开启导风板5清洁功能，有利于实现在空调室内机100长期工作过程中、导风板5保持洁净。例如，在空调室内机100停机时，开关门2关闭出风口12，导风板5处于关闭出风口12的位置，当空调室内机100开机时，开关门2移动至打开出风口12的位置，在此过程中开关门2带动清扫条3移动以扫除导风板5表面上的灰尘，接着退出导风板5清洁功能，最后导风板5可转动至预设角度λ，风道11内的与室内换热器6换热后的气流吹向室内空间以调节室内环境的温度。
在本申请的一些实施例中，在接收到关闭空调室内机100的指令时，先开启导风板5清洁功能以清洁导风板5，在退出导风板5清洁功能后关闭空调室内机100。由此，在关闭空调室内机100时，就可以实现对导风板5的除尘，从而不必用户刻意去开启导风板5清洁功能，有利于保证在空调室内机100长期工作过程中、导风板5保持洁净。例如， 空调室内机100的控制装置接收到关闭空调室内机100的指令，首先控制风轮停转，接着空调室内机100开启导风板5清洁功能，导风板5关闭出风口12，随后开关门2由打开出风口12的位置移动至关闭出风口12的位置，在此过程中开关门2带动清扫条3移动以扫除导风板5表面上的灰尘，最后退出导风板5清洁功能。
