Description

空调器及其控制方法、控制装置 技术领域
本发明涉及空调技术领域，具体涉及一种空调器及其控制方法、控制装置。
背景技术
空调器通常具有制冷模式和制热模式，通过冷媒在压缩机-冷凝器-节流部件-蒸发器-压缩机形成的回路中的循环流动，伴随着冷媒的相变，可以向室内空间提供温度适合的空气。如在空调器处于制热模式的情形下，室内换热器作为发放热量的冷凝器，而在空调器处于制冷模式的情形下，室内换热器作为发放冷量的蒸发器。
空调室内机的壳体具有送风口，空调室内机的壳体内的、温度得以调节的空气经送风口发放至室内。为了调整送风品质(如送风方向、送风速度等)，通常在送风口处配置有能够导风的结构。导风板为用于导风的结构之一，通过导风板相对空调室内机的枢转运动，可以调节送风品质，从而在送风量不变的前提下，能够在一定程度上改善室内空间的用户体验。
导风板的形式主要包括如下两种，一种为直接配置在壳体对应于送风口的位置的导风板，通常称作小导风板。另一种为配置在小导风板外侧的导风板，通常称作第二导风板。小导风板的转动频率和转动方式往往比较丰富，因此通常小导风板通常配置有作为驱动其转动的电机。较之于小导风板，第二导风板的转动方式通常较为简单，因此通常 可以通过手动的方式完成(当然电机驱动的方式也可以)。如何通过大、小导风板的协作来改善空调器的送风品质，具有很大的提升空间。
相应地，本领域需要一种新的技术方案来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有的空调器的送风品质有待进一步提升的问题，本发明第一方面提供了一种空调器的控制方法，所述空调器包括室外部分和室内部分，所述室内部分包括壳体，所述壳体具有送风口，所述送风口配置有导风组件，所述导风组件包括枢转设置于所述壳体对应于所述送风口的位置的第一导风板以及沿所述送风口向室内空间发放空气的方向位于所述第一导风板的下游侧的第二导风板，所述控制方法包括：在第二导风板转动至第一位置的情形下，所述第二导风板只能相对所述送风口间断地处于某一个或者某几个位置；其中，沿所述送风口向室内空间发放空气的方向观察，所述第二导风板在该第一位置时至少一部分对准所述送风口。
通过这样的设置，能够谋求尽量降低空气经送风口直接吹人的现象发生的概率。具体而言：
一方面，在送风品质经第一导风板被调整的基础上，允许经第二导风板进一步调整经送风口发放至室内空间的空气的送风品质。
另一方面，在第二导风板处于对应于防直吹功能的第一位置时，通过将第一导风板的位置进行限定，从而能够有效地降低干涉防直吹功能实现的因素出现的概率。
可以理解的是，第一位置可以是沿发放空气的方向恰好对准送风口的位置，也可以是绝大部分对准或者比例无限定的部分对准。如假设空调器的使用场景为教室等用户以坐姿为主的情形下，对于挂机而 言，第二导风板并不需要完全处于恰好对准送风口的位置，在处于该位置之下的位置时，即可完全实现防直吹的功能。
对于上述空调器的控制方法，在一种可能的实施方式中，所述的“在第二导风板转动至第一位置的情形下，所述第一导风板只能相对所述送风口间断地处于某一个或者某几个位置”包括：在第二导风板转动至第一位置、允许所述第一导风板相对所述送风口处于的位置为多个的情形下，在将第一导风板切换至后一个位置之前，第一导风板处于前一个位置的时长不小于第一设定时长。
通过这样的设置，能够谋求进一步降低干涉防直吹功能实现的因素出现的概率。
具体而言，在将允许第一导风板到达的位置进行限定之后，通过尽量地降低第一导风板在不同的位置之间的活动频率，对第二导风板的转动自由度进行约束，从而能够谋求第一导风板相对壳体的位置大致较为稳定，因此能够借助于第二导风板的阻挡作用有效地实现空调器的防直吹功能。
可以理解的是，本领域技术人员可以根据实际需求灵活地选择第一设定时长。如：第一设定时长为不小于3min的某一值。
对于上述空调器的控制方法，在一种可能的实施方式中，所述的“在允许所述第一导风板相对所述送风口处于的位置为多个的情形下，在将第一导风板切换至后一个位置之前，第一导风板处于前一个位置的时长不小于第一设定时长”包括：在允许所述第一导风板相对所述送风口处于的位置为多个的情形下，所述第一导风板相对所述送风口处于前一个位置的时长到达第一设定时长之后，首先停留第二设定时长，之后切换至后一个位置。
通过这样的设置，能够谋求以进一步降低第一导风板的活动频率的方式保证空调器的防直吹功能能够被更好地实现。
可以理解的是，与第一设定时长类似，本领域技术人员可以根据实际需求灵活地选择第二设定时长。如第二设定时长为固定的3min。
需要特别说明的是，在允许切换和切换之间增加第二设定时长，并非简单地将第一导风板停留在前一个位置的时间进行加长处理。而是作为一个增设的、特定的中间时间段，通过对其进行灵活地设置，来进一步改善空调器的防直吹功能。
因此，对应于第二设定时长期间的第一导风板的位置可以根据实际情况灵活调整，示例性地：第一导风板可以作一个微小的转动，如动至离前一个位置较近、后一个位置较远的位置等。
对于上述空调器的控制方法，在一种可能的实施方式中，在“所述第一导风板相对所述送风口处于前一个位置的时长到达第一设定时长之后，首先停留第二设定时长，之后切换至后一个位置”的步骤中，“首先停留第二设定时长”具体为：首先在该前一个位置停留第二设定时长。
通过这样的设置，给出了一种具体的第二设定时长期间的第一导风板的位置和姿态形式。
对于上述空调器的控制方法，在一种可能的实施方式中，所述的“在第二导风板转动至第一位置的情形下，所述第二导风板只能相对所述送风口间断地处于某一个或者某几个位置”包括：在第二导风板转动至第一位置的情形下，所述第二导风板固定地处于开度不小于设定开度的一个位置。
通过这样的设置，以第一导风板固定不动的方式促进了空调器的防直吹功能的实现程度。
可以理解的是，本领域技术人员可以根据实际需求灵活地选择设定开度的值。如设定开度为不小于最大开度的70％的某一值等。
对于上述空调器的控制方法，在一种可能的实施方式中，所述控制方法包括：在第二导风板转动至第二位置的情形下，所述第一导风板根据接收到的指令相对所述送风口自由转动。
通过这样的设置，能够促进空调器在非防直吹状态下的混风程度。
以挂机为例，送风口通常设置于壳体前侧靠下的位置，此时的第二位置大致对应的是第二导风板的最低位置。此时，下置的第二导风板与送风口的下沿会形成一个外置风道，从而在空调器向室内送风的过程中在送风口的下沿形成一个负压区域。基于这样的配置，会促进经空调器送出的风与外置风道从室内空间吸入的风进行更大程度的混合。
可以理解的是，为了保证负压区域的显著性，可以根据实际情况调整第二位置的具体形式。如：比最低位置略高；等。
对于上述空调器的控制方法，在一种可能的实施方式中，所述壳体在靠近顶部的位置具有回风口，所述控制方法包括：在第二导风板转动至第三位置的情形下，使所述第二导风板遮挡所述回风口的至少一部分。
通过这样的设置，能够保证空调器在停机状态下的洁净程度。
具体而言，通过第二导风板将回风口的至少一部分(通常情形下是相当一部分)遮挡，能够有效地防止发生如灰尘、虫子等异物在空调器停机期间经回风口进入壳体内的现象。
仍以挂机为例，回风口设置于壳体顶部靠前的位置，此时的第三位置大致对应的是第二导风板的最高位置。
对于上述空调器的控制方法，在一种可能的实施方式中，所述空调器包括限位部，所述限位部包括：第一部分，其具有多个安置位；以及第二部分；以便：在所述第二导风板相对所述壳体转动的过程中，所述第二导风板在到达与任意安置位相对应的位置时，能够通过所述第二部分与所述安置位的配合使所述第二导风板处于与该安置位相对应的位姿。
通过这样的设置，保证了第二导风板在处于设定的位置期间，具有良好的稳定性。
具体而言，此外，第二导风板通常只需要固定在几个位置，因此，在第二导风板相对壳体转动到其中任意一个位置的情形下，如何保证第二导风板在处于该位置时的稳定性，是影响第二导风板的工作性能的重要因素之一。
可以理解的是，在保证第二导风板能够相对壳体旋转以及在旋转到达之后可靠停留的功能能够得以实现的基础上，本领域技术人员能够根据实际情况选择第一部分和第二部分的具体形式，如可以是：第一部分为形成于壳体侧部的筒状结构，筒状结构的内壁周向设置有多个槽结构，第二部分为设置于第二导风板上的卡爪，在旋转到达的情形下，卡爪能够卡置于相应的槽结构内，从而使第二导风板能够在无外力的状态下持续地停留在该位置；等。
本发明第二方面提供了一种控制装置，所述控制装置包括存储器和处理器，其中，所述存储器存储有能够执行前述任一项所述的空调器的控制方法的程序，其中，所述处理器能够调用所述程序并执行前述任一项所述的空调器的控制方法。
可以理解的是，该控制装置具有前述的空调器的控制方法的所有技术效果，在此不再赘述。
本发明第三方面提供了一种空调器，该空调器包括控制模块，所述控制模块用于执行前述任一项所述的空调器的控制方法。
可以理解的是，该空调器具有前述任一项所述的空调器的控制方法的所有技术效果，在此不再赘述。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
空调器通常包括室外部分和室内部分，对于有的机型而言(如窗机等)，室外部分和室内部分是集成在同一个壳体内。而对于绝 大部分机型而言，室外部分和室内部分为分体式结构，其中的室外部分称作空调室外机，室内部分称作空调室内机，二者之间通过管路连接。
以分体式结构的空调器为例，空调室外机主要包括壳体以及设置于壳体内的压缩机、室外风机和室外换热器(通常称作冷凝器)，空调室内机主要包括壳体以及设置于壳体内的室内换热器(通常称作蒸发器)。当冷媒沿压缩机→室外换热器→室内换热器→压缩机的回路循环流动时，空调器处于制冷循环；而当冷媒沿压缩机→室内换热器→室外换热器→压缩机的回路循环流动时，空调器处于制热循环。
分体式结构的空调器通常包括柜机、挂机以及嵌入式空调器等。以挂机为例，空调器的空调室内机的壳体的背部通常固定设置于室内空间的墙壁，壳体上具有送风口和回风口(如底部送风、顶部回风)，壳体内主要设置有室内换热器、室内风机、接水盘和电控箱等，空调器处于制冷/制热循环的过程中，在室内风机的作用下，室内空间的一部分空气经回风口被抽入壳体的内部，与室内换热器的表面进行热交换之后，这部分空气的温度得以降低/升高，之后这部分温度降低的空气经送风口被再次送入室内空间，如此反复，即可逐渐将由于冷媒的相变以及循环流动产生的冷量/热量逐渐发放至室内空间。在向室内空间发放冷量的同时，蒸发器的表面会产生冷凝水。为了保证制冷的可持续性，需要将这部分冷凝水及时地排出至室外侧。设置于室内换热器下方的接水盘主要用于收集室内换热器表面产生的冷凝水，壳体上通常设置有与接水盘对接的排水接头，排水接头配置有排水管，排水管的上游侧与排水接头匹配相连，下游侧伸出室外侧，通过排水管将接水盘收集的冷凝水及时地排出，保证了空调器的运行可持续性。
参照图1至图5，图1示出本发明一种实施例的空调器的状态示意图一，图2示出本发明一种实施例的空调器的状态示意图二，图3示 出本发明一种实施例的空调器的状态示意图三，图4示出本发明一种实施例的空调器中限位部的第一部分的结构示意图，图5示出本发明一种实施例的空调器中第二导风板的结构示意图。如图1至图5所示，本发明的空调器100中，空调室内机的壳体1的顶部具有回风口11，回风口为格栅结构，壳体1的底部具有送风口(未标出)，送风口配置有导风组件，导风组件包括枢转设置于所述壳体对应于送风口的位置的第一导风板21(通常称作小导风板)以及位于第一导风板的下游侧的第二导风板22(通常称作大导风板)，第二导风板大致为U形结构，壳体的两侧具有侧部，U形结构包括对应于送风口位置的、作为有效部分的中间部分221以及位于中间部分两侧的分别与两个侧部连接的伸出部分222，伸出部分的外侧以一体成型的方式设置有装饰盖23。随着第一导风板相对壳体的转动，能够有效地调整经送风口发放至室内空间的空气的送风品质。在此基础上，通过第二导风板相对壳体的转动，进一步调整经送风口发放至室内空间的空气的送风品质。
在本发明中，空调器还包括限位部，具体而言，在壳体的两个侧部(以及相对应的伸出部分)的位置分别设置有限位部。限位部的功能主要包括两个方面：一方面，大导风板能够通过限位部相对壳体枢转运动，另一方面，大导风板在到达任意有效的调节位置时，能够通过限位部持续处于该有效的调节位置。
在一种可能的实施方式中，限位部的结构主要包括设置于壳体的第一部分以及设置于伸出部分的第二部分，其中，第一部分包括沿壳体的侧部向外延伸的筒状结构31，筒状结构的内壁形成有多个安置位，安置位为形成于筒状结构的内壁上的、沿筒状结构的轴向分布的槽结构32；第二部分为能够匹配卡置于安置位的卡爪4，卡爪包括主体和伸出端，在卡置好的状态下，主体沿筒状结构的径向紧密地抵接至槽结构内，伸 出端的外侧卡置于筒状结构内侧端部对应于槽结构的位置。为了便于卡爪能够顺利地划入槽结构内，可以在槽结构的外侧设置有引导面。
这样一来，在第二导风板相对壳体转动至如图1、图2、图3示出的设定状态的位置时，第二导风板通过卡爪与槽结构的配合，即在前述的“主体沿筒状结构的径向紧密地抵接至槽结构内，伸出端的外侧卡置于筒状结构内侧端部对应于槽结构的位置”的约束下使第二导风板持续处于与相应的位置相对应的位姿。在外力的作用下，卡爪能够克服槽结构的约束从而实现第二导风板相对壳体的转动。
如在本实施例中，筒状结构的内壁设置有8个槽结构(共四组，每组包括相邻设置的两个槽结构)，相应地，在伸出部分上沿周向设置有4个卡爪(共四组，每组仅一个卡爪)。这样一来，对于同一组槽结构而言，当卡爪从与其中的一个相匹配的位置转动至与另一个相匹配的位置时，第二导风板实现了小角度的转动。对于不同组槽结构而言，当卡爪从与其中的一组中的某一个槽结构相匹配的位置转动至与另一组中的某一个槽结构相匹配的位置时，第二导风板实现了大角度的转动。
可以理解的是，上述的限位部仅为一种示例性的描述，在满足限位部的功能的前提下，本领域技术人员可以根据实际情况灵活地选择限位部的具体形式。如最简单地，将卡爪和槽结构的载体互换，即卡爪设置于壳体的侧部而槽结构设置于第二导风板的伸出部分等。
如图6所示，图6示出本发明一种实施例的空调器的控制方法在防直吹模式期间的流程示意图。下面参照图6以及进一步参照图1至图3来阐述本发明的空调器的控制方法。
在图1示出的防直吹模式期间，将第二导风板旋转至沿空气向室内空间发放空气的方向恰好对准送风口的位置，第一导风板允许处于两个开度，一个是最大的开度(称作开度一)，另一个是对应于最大 开度的70％的开度(称作开度二)。第一导风板处于开度二的时长第一设定时长之后，在开度二的位置继续停留第二设定时长，然后切换至开度一并保持。本实施例中，第一设定时长取5min，第二设定时长取3min。这样一来，经送风口发放至室内空间的空气经过第二导风板的阻挡，由于气流被打散，因此能够明显降低由于直吹到人身上引起的不适感。
在图2示出的非防直吹模式期间，即对送风方向无特别限制的、普通的制冷制热模式期间，将第二导风板大致旋转至作为第二位置的最低位置，此时第二导风板的中间部分大致为水平状态，第一导风板可以随着空调器的指令转动至任意位置。
在这种情形下，下置的第二导风板与送风口的下沿会形成一个外置风道。具体而言，在空调器送风的过程中，送风口的下沿会出现负压区域。这样一来，经空调器送出的风与外置风道吸入的室内空间的风会产生一定程度的混合，这样的混合会提升室内空间内冷、热空气的混合效率，从而改善空调器的制冷制热性能。
可以理解的是，为了突显外置风道的作用，可以根据实际情况对第一导风板的转动范围作一定的限制，如在允许的前提下，将第一导风板的转动角度限定为能够促进冷热风更好地混合的角度等。
在图3示出的停机状态下，可以将第二导风板继续向上旋转至对应于回风口的位置，如尤其在长时间不用空调器的季节，将第一导风板大致旋转至作为第三位置的最高位置，此时第二导风板的中间部分位于回风口的上方，从而能够有效地阻挡部分灰尘、虫子等异物经回风口落入空调室内机的壳体的内部。
基于上述空调器的控制方法，空调器还包括控制模块，可以通过控制模块来对空调器进行如上的控制方法，从而特别通过第一导风板和第二导风板协作的方式改善空调器的整机性能。
在本发明的描述中，“模块”、“处理器”可以包括硬件、软件或者两者的组合。一个模块可以包括硬件电路，各种合适的感应器，通信端口，存储器，也可以包括软件部分，比如程序代码，也可以是软件和硬件的组合。处理器可以是中央处理器、微处理器、图像处理器、数字信号处理器或者其他任何合适的处理器。处理器具有数据和/或信号处理功能。处理器可以以软件方式实现、硬件方式实现或者二者结合方式实现。非暂时性的计算机可读存储介质包括任何合适的可存储程序代码的介质，比如磁碟、硬盘、光碟、闪存、只读存储器、随机存取存储器等等。
本领域技术人员能够理解的是，本发明实现其控制方法中的全部或部分流程，也可以通过计算机程序来指令相关的硬件来完成，所述的计算机程序可存储于一计算机可读存储介质中，该计算机程序在被处理器执行时，可实现上述各个方法实施例的步骤。其中，所述计算机程序包括计算机程序代码，所述计算机程序代码可以为源代码形式、对象代码形式、可执行文件或某些中间形式等。所述计算机可读介质可以包括：能够携带所述计算机程序代码的任何实体或装置、介质、U盘、移动硬盘、磁碟、光盘、计算机存储器、只读存储器、随机存取存储器、电载波信号、电信信号以及软件分发介质等。需要说明的是，所述计算机可读介质包含的内容可以根据司法管辖区内立法和专利实践的要求进行适当的增减，例如在某些司法管辖区，根据立法和专利实践，计算机可读介质不包括电载波信号和电信信号。
进一步，应该理解的是，由于控制模块的设定仅仅是为了说明本发明的系统的功能单元，因此控制模块对应的物理器件可以是处理器本身，或者处理器中软件的一部分，硬件的一部分，或者软件和硬件结合的一部分。因此，控制模块的数量为一个仅仅是示意性的。
本领域技术人员能够理解的是，可以根据实际情况，对控制模块进行适应性地拆分。对控制模块的具体拆分形式并不会导致技术方案偏离本发明的原理，因此，拆分之后的技术方案都将落入本发明的保护范围内。
需要指出的是，尽管上述实施例中将各个步骤按照特定的先后顺序进行了描述，但是本领域技术人员可以理解，为了实现本发明的效果，不同的步骤之间并非必须按照这样的顺序执行，其可以同时执行或以其他顺序执行，也可以增加、替换或者省略某些步骤，这些变化都在本发明的保护范围之内等。如将防直吹模式期间的第二设定时长省略或者将第二设定时长期间第二导风板的位姿进行调整等。
需要说明的是，尽管以如上具体方式所构成的控制方法作为示例进行了介绍，但本领域技术人员能够理解，本发明应不限于此。事实上，用户完全可根据以及实际应用场景等情形灵活地调整相关的步骤、步骤中的参数等要素。
至此，已经结合优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
