空调器的控制方法
本申请基于申请号为201811527244.X、申请日为2018.12.13的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及空气调节技术领域，例如涉及一种空调器的控制方法。
背景技术
近年来，随着生活水平的提高，人们对生活质量的追求也越来越高。例如，越来越多的人们选择在家中安装新风机，以改善室内的空气质量。但是，新风机的安装不仅占用很大一部分室内面积，而且安装过程困难、麻烦，安装完毕后还影响室内的美观。
为解决上述问题，市场上出现了一种带有新风功能的空调器，其在空调的正常工作模式上，还添加了新风功能，以便将室外的新风引入室内，降低室内的二氧化碳浓度，改善室内空气的新鲜度。但是，目前这种空调器的控制方式大多是将新风功能嵌入到空调的几种工作模式中，当运行新风功能时，便无法再同时进行制冷制热，进而导致了在引入室外新风的同时，室内温度的变化过大，使得室内的舒适性下降，严重影响了用户体验。
相应地，本领域需要一种新的空调器的控制方法来解决上述问题。

在一些可选实施例中，所述基于检测结果，选择性地控制所述温度调节单元和/或所述新风单元运行，以同时调节室内的二氧化碳浓度和温度，包括：
在所述温度补偿功能开启式，基于室内环境温度和所述二氧化碳浓度，分别控制所述温度调节单元和所述新风单元运行；
否则，在所述温度补偿功能未开启时，基于所述二氧化碳浓度，控制所述新风单元运行，同时控制与所述新风单元对应的导风板向上送风。

S100、获取室内的二氧化碳浓度，如通过设置于空调器进风口或出风口的二氧化碳传感器来获取室内的二氧化碳浓度，或者通过设置于室内任意位置且与空调器通过有线或无线通信的二氧化碳传感器获取室内的二氧化碳浓度；
S200、在二氧化碳浓度大于第一预设值时，获取空调器的运行状态，如在二氧化碳浓度大于1000ppm时，证明此时室内二氧化碳浓度偏高，需要进行调节，此时首先获取空调器的运行状态，再根据运行状态决定调节方式，其中，空调器的运行状态可以是开机状态或关机状态，二者的区别在于温度调节单元是否正在工作；
S300、基于获取结果，选择性地控制温度调节单元和/或新风单元运行，如在空调器的运行状态为开机状态时，证明温度调节单元已经在工作，此时控制新风单元运行，以同时调节室内的温度和二氧化碳浓度，提供室内的舒适度和空气新鲜度；再如， 在空调器的运行状态为关机状态时，证明温度调节单元未工作，此时可以通过同时启动温度调节单元和新风单元，以同时调节室内的温度和二氧化碳浓度，提高室内的舒适度和空气新鲜度。
从上述描述可以看出，本公开的空调器的控制方法能够在室内二氧化碳浓度过高时，通过对温度调节单元和新风单元进行联合控制，提高室内舒适度，提升用户体验。具体而言，在室内的二氧化碳浓度大于第一预设值时，证明此时室内空气质量较差，需要引入室外新风以改善空气质量。但是引入室外新风势必会对室内空气的温度产生影响，导致室内温度变化过大，降低室内舒适度。此时，通过获取空调器的运行状态，并且根据运行状态的不同选择性地控制温度调节单元和/或新风单元运行，能够对室内的温度和二氧化碳浓度同时进行调整，提高室内舒适度的同时，降低室内二氧化碳浓度，提高室内空气新鲜度和用户体验。
在一种可能的实施方式中，步骤S300包括：
在空调器的运行状态为关机状态时，检测关机新风模式是否开启；在关机新风模式未开启时，控制空调器发出报警信息；在关机新风模式开启时，基于室内环境温度和二氧化碳浓度，分别控制温度调节单元和新风单元运行，以同时调节室内的二氧化碳浓度和温度。具体而言，在空调器的运行状态为关机状态时，证明此时空调器的温度控制单元并未工作，此时室内二氧化碳浓度过高，会影响室内的空气质量。此时检测关机新风模式是否开启，在没开启时，发出警报信息，如通过向用户的终端设备上安装的APP推送室内空气质量信息的方式提醒用户需要开启关机新风功能，或者通过空调器上的声光元器件提示用户此时的空气质量较差。而用户接收到该信息时，可以通过手动的方式开启关机新风模式，当然也可以通过遥控器或手机APP等将关机新风模式设置为自动开启。在关机新风模式开启时，基于室内环境温度控制温度调节单元的运行，基于二氧化碳浓度控制新风单元的运行。
例如，在一种可能的实施方式中，当空调器获取到室内的温度小于18℃时，则空调器进入新风制热模式，即温度调节单元以制热模式运行，新风单元正常运行，以在引入新风的同时调节室内温度，避免室内温度过低而影响舒适度；当空调器获取到的室内的温度在18℃到30℃之间，则空调器进入新风送风模式，即温度调节单元不运行，新风单元正常运行，以引入新风；当空调器获取到室内的温度大于30℃时，则空调器进入新风制冷模式，即温度调节单元以制冷模式运行，新风单元正常运行，以在引入新风的同时调节室内温度，避免室内温度过高而影响舒适度。进一步地，在运行过程中，基于室内温度的变化，还可以控制温度调节单元在不同的模式下切换运行。如当空调器以新风制热模式运行时，空调器获取到室内的温度为25℃，此时空调器切换为新风送风模式运行，即保持新风单元的运行状态不变，温度调节单元停止运行。其他模式之间的切换原理与此类似，在此不再赘述。
通过上述控制方式，本公开的空调器的控制方法能够在引入室外新风的同时，利用温度调节模块在模式之间切换对室内温度进行动态调节，提高室内的舒适度和空气的新鲜度。并且，是否进行动态调节选择的是室内的温度，对于用户来说更加直接准确，提升用户体验。通过在关机新风模式未开启时，发出报警信息，还能够及时向用户传达空气质量信息，提醒用户及时开启关机新风模式，提升用户体验。通过让用户选择是否开启关机新风模式，还可以使得用户自由决定该新风功能的使用时间，避免由于新风功能产生的噪音影响休息。
在一种可能的实施方式中，为了进一步提升用户体验，在关机模式开启时，还可以进一步检测温度补偿功能是否开启，如果温度补偿功能开启，证明用户想在引入新风的同时提高室内环境的舒适度，则此时同时控制温度调节单元和新风单元运行；如果温度补偿功能未开启，证明此时用户只想引入新风，那么此时控制新风单元运行，同时控制新风单元的导风板向上送风，以避免新风对人体直吹。其中，在新风单元与空调器单独设置时，该导风板为新风单元的出风口设置的导风板，在新风单元与空调器一体设置时，导风板为空调器的出风口设置的导风板。
在另一种可能的实施方式中，步骤S300还包括：
在空调器的运行状态为开机状态时，检测自动新风模式是否开启；在自动新风模式未开启时，控制空调器发出报警信息；在自动新风模式开启时，基于二氧化碳浓度控制新风单元运行。具体而言，在空调器的运行状态为开机状态时，证明此时空调器的温度控制单元正在对室内温度进行调节，此时室内二氧化碳浓度过高，会影响室内的空气质量。此时检测自动新风模式是否开启，在没开启时，发出警报信息；如上述的通过向用户的终端设备上安装的APP推送室内空气质量信息的方式提醒用户需要开启关机新风功能，或者通过空调器上的声光元器件提示用户此时的空气质量较差。而用户接收到该信息时，可以通过手动的方式开启自动新风模式，当然也可以通过遥控器或手机APP等将自动新风模式设置为自动开启。在自动新风模式开启时，基于室内环境温度控制温度调节单元的运行，基于二氧化碳浓度控制新风单元的运行。如在室内的二氧化碳浓度过大时，可以控制新风单元的新风风机高速运行，以快速降低室内的二氧化碳浓度，而空气调节单元则根据室内的温度，自动选择对应的工作模式和室内风机的风速进行匹配，提高室内环境的舒适度。
通过上述控制方式，本公开的空调器的控制方法能够在提高室内的舒适度的前提下，引入室外新风，降低室内的二氧化碳浓度，提高空气的新鲜度，并且温度调节单元与新风单元能够各自独立工作，互不影响。通过在自动新风模式未开启时，发出报警信息，还能够及时向用户传达空气质量信息，提醒用户及时开启自动新风模式，提升用户体验。
在另一种可能的实施方式中，空调器的控制方法还包括：在新风单元和/或温度调节单元运行时，基于二氧化碳浓度，控制新风风机的风速和/或室内风机的风速。例如，如下表1所示，在二氧化碳浓度大于1500ppm时，需要大量引入室外新风，以快速降低室内二氧化碳浓度，此时新风风机的风速为高风，而为了提高室内温度的稳定，此时室内风机的风速也为高风；再如，在二氧化碳浓度小于800pm时，证明此时室内二氧化碳浓度已经处于正常范围内，此时新风风机可以关闭，而是内风机风速可以运行在静音风速，以免打扰用户的正常工作和休息。
表1 二氧化碳浓度与风速对照表
二氧化碳浓度 >1500 1000-1500 800-1000 <800
室内风机风速 高风 中风 低风 静音
新风风机风速 高风 高风 低风 关闭
通过上述控制方式，本公开的空调器的控制方法能够基于室内的具体情况进行灵活控制，在提高室内舒适度和空气新鲜度的前提下，高效地完成对室内空气的调节。
在另一种可能的实施方式中，空调器的控制方法还包括：在新风单元运行时，比 较室内的二氧化碳浓度与第二预设值的大小；在二氧化碳浓度小于第二预设值时，控制新风风机以设定的风速继续运行设定的时间。具体而言，第二预设值可以为1000ppm，在室内二氧化碳浓度小于1000ppm时，证明此时室内空气质量已经得到改善并符合停机标准，此时控制新风风机以设定的风速继续运行设定的时间，如控制新风风机以低速运行30分钟或1小时，不仅能够在基本不产生噪音的前提下，使室内的二氧化碳浓度进一步降低至更加优秀的水平，而且还能够避免新风风机在达到停机阈值时停止运行后室内空气质量立即升高而导致的新风风机频繁启停的现象出现，提升用户体验。
在另一种可能的实施方式中，空调器的控制方法还包括：在新风单元运行时，控制空调器显示当前的二氧化碳浓度或将当前的二氧化碳浓度发送至终端设备。具体而言，在新风单元运行时，证明此时室内二氧化碳浓度偏高，需要引入室外新风。在新风风机工作过程中，通过将二氧化碳浓度显示在空调器上或实时发送至终端设备上，如通过数字或更改指示灯颜色的方式显示在空调器的显示面板上，或将二氧化碳浓度发送至空调遥控器或者用户的手机APP上，能够达到给用户直观显示当前空气质量的效果，进一步提升用户体验。
需要说明的是，上述的实施方式仅仅用于阐述本公开的原理，并非旨在于限制本公开的保护范围。在不偏离本公开原理的前提下，本领域技术人员可以对上述设置方式进行调整，以便本公开能够适用于更加具体的应用场景。
例如，在一种可替换的实施方式中，第一预设值和第二预设值并非一成不变，本领域技术人员可以对其进行调整，以便其适应更加具体的应用场景。如第一预设值和第二预设值可以同时设置为900ppm、1100ppm等，也可以分别设置成不同的数值，如第一预设值设置为1200ppm，第二预设值设置为800ppm。
再如，在另一种可替换的实施方式中，上述各个步骤之间的先后关系并非不变，本领域技术人员可以结合具体的应用场景进行调整。如可以将获取室内二氧化碳浓度的步骤调整至获取空调器的运行状态之后，或者在二氧化碳浓度值大于第一预设值时，先发出报警信息，再检测空调器的关机新风模式是否开启等。
下面结合图2对本公开的空调器的控制流程进行简要说明。其中，图2为本公开的一种可能的实施方式中空调器的控制方法的逻辑图。
如图2所示，在一种可能的实施方式中，首先空调器获取室内的二氧化碳浓度，并判断该浓度是否大于1000ppm→如果该浓度小于1000ppm，则返回继续获取；如果该浓度大于1000ppm，则获取空调器的运行状态：(1)在空调器处于开机状态时，判断自动新风模式是否开启→如果没有开启，则向手机APP推送报警信息，如果已经开启，则控制新风风机运行→运行过程中持续判断二氧化碳浓度是否小于1000ppm→如果该浓度不小于1000ppm，则控制新风风机继续运行；如果该浓度小于1000ppm，则控制新风风机以低风运行1小时后停止运行。(2)在空调器处于关机状态时，判断关机新风模式是否开启→如果没有开启，则向手机APP推送报警信息，如果已经开启，则进一步判断温度补偿功能是否开启→如果温度补偿功能未开启，则控制新风风机单独运行；如果温度补偿功能开启，则控制新风单元和温度控制单元同时运行。
至此，已经结合附图所示的实施方式描述了本公开的技术方案，但是，本领域技术人员容易理解的是，本公开的保护范围显然不局限于这些具体实施方式。在不偏离本公开的原理的前提下，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公开的保护范围之内。
