Description

用于空调自清洁的控制方法及装置、空调
本申请基于申请号为202110137232.1、申请日为2021年2月1日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
本申请涉及智能家电技术领域，例如涉及一种用于空调自清洁的控制方法及装置、空调。
背景技术
空调器制热或制冷运行过程中，外界空气中所夹杂的灰尘、大颗粒杂物等会进入空调器，附着在空调换热器的表面，直接影响到换热器与外界空气的换热，并且影响出风质量。为了保证换热效率及出风质量，需要定期对空调换热器进行清洁处理。目前用户通过人工启动空调自清洁功能的方式进行空调换热器的自清洁操作。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：用户人工启动空调自清洁功能的间隔时间过长，换热器灰尘堆积过多，空调制热或制冷效果减弱，而且容易影响人们的身体健康；而由于自清洁操作会扰乱空调正常的制冷或制热模式，用户人工启动空调自清洁功能的间隔时间过短，容易影响空调正常的制冷或制热调节，降低用户体验。因此，如何能够确定启动空调自清洁的恰当时机，成为亟待解决的问题。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。
本公开实施例提供了一种用于空调自清洁的控制方法及装置、空调，以解决目前无法很好地确定启动空调自清洁的恰当时机的问题。
在一些实施例中，用于空调自清洁的控制方法包括：在空调稳定运行的情况下，获得空调的换热器与风扇之间的环境温度；根据环境温度与预设温度的比例关系，控制空调执行自清洁操作。
在一些实施例中，用于空调自清洁的控制装置包括处理器和存储有程序指令的存 储器，处理器被配置为在执行程序指令时，执行前述用于空调自清洁的控制方法。
在一些实施例中，空调包括前述用于空调自清洁的控制装置。
本公开实施例提供的用于空调自清洁的控制方法及装置、空调，可以实现以下技术效果：
当空调的风扇转动时，如果换热器没有积聚灰尘，换热器可以很好地与外环境进行换热，换热器与风扇之间的环境温度相对较高，而当换热器积聚灰尘较多，换热器无法很好与外环境进行换热，换热器与风扇之间的环境温度相对较低，因此可以在空调稳定运行的情况下，获得空调的换热器与风扇之间的环境温度，并根据环境温度与预设温度的比例关系，控制空调执行自清洁操作，从而能够更好地确定启动空调自清洁的恰当时机，保证空调良好的制热或制冷调节，提高用户的使用体验。
以上的总体描述和下文中的描述仅是示例性和解释性的，不用于限制本申请。
附图说明
一个或多个实施例通过与之对应的附图进行示例性说明，这些示例性说明和附图并不构成对实施例的限定，附图中具有相同参考数字标号的元件示为类似的元件，附图不构成比例限制，并且其中：
图1是本公开实施例提供的一个用于空调自清洁的控制方法的流程示意图；
图2是本公开实施例提供的另一个用于空调自清洁的控制方法的流程示意图；
图3是本公开实施例提供的一个用于空调自清洁的控制装置的结构示意图。
具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
本公开实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开实施例的实施例。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
除非另有说明，术语“多个”表示两个或两个以上。本公开实施例中，字符“/”表示前后对象是一种“或”的关系。例如，A/B表示：A或B。术语“和/或”是一种描述对象的关联关系，表示可以存在三种关系。例如，A和/或B，表示：A或B，或，A和B这三种关系。
结合图1所示，本公开实施例提供一种用于空调自清洁的控制方法，包括以下步骤：
S101:在空调稳定运行的情况下，获得空调的换热器与风扇之间的环境温度。
在实际应用中，在利用换热器与风扇之间的环境温度对换热器的灰尘积聚程度进行判断时，只针对空调稳定运行时获得的环境温度进行判断，空调稳定运行时的运行模式可以是高风档制冷运行模式、中风档制冷运行模式或低风档制冷运行模式。由于空调的换热器与风扇之间的环境温度在空调不稳定运行(例如空调处于放频状态)时受外界环境影响较大，因而此时的环境温度不能准确地反映换热器的灰尘积聚程度。
可选地，换热器包括室内换热器，风扇包括设置于空调室内机的贯流风扇；获得空调的换热器与风扇之间的环境温度，包括：获得位于室内换热器与贯流风扇之间的第一温度检测点的第一环境温度；其中，第一温度检测点位于贯流风扇机壳的中间位置，且位于贯流风扇机壳与室内换热器之间的中间位置；确定第一环境温度为环境温度。
考虑到贯流风扇出风口处的温度容易受外界环境温度的影响，室内换热器铝箔片之间的温度无法准确反映室内换热器整体的灰尘积聚程度，而且贯流风扇机壳处风量较小，吹风对该处的温度影响小，因而将第一温度检测点设置于贯流风扇机壳的中间位置，以及贯流风扇机壳与室内换热器之间的中间位置，这样检测到的环境温度既不容易受外界环境的影响，也能够更为准确地反映室内换热器整体的灰尘积聚程度。
可选地，换热器包括室外换热器，风扇包括设置于空调室外机的轴流风扇；获得空调的换热器与风扇之间的环境温度，包括：获得位于室外换热器与轴流风扇之间的第二温度检测点的第二环境温度；其中，第二温度检测点位于室外换热器的翅片表面；获得位于室外换热器与轴流风扇之间的第三温度检测点的第三环境温度；其中，第三温度检测点位于轴流风扇的转轴处；获得位于室外换热器与轴流风扇之间的第四温度检测点的第四环境温度；其中，第四温度检测点位于室外换热器的翅片表面与轴流风扇的转轴之间的中间位置；计算获得第二环境温度、第三环境温度与第四环境温度的权重环境温度；确定权重环境温度为环境温度。
由于空调室外换热器与风扇之间的环境温度受外界环境的影响因素较大，因而选取多个温度检测点，通过多个温度检测点检测到的温度来综合确定室外换热器与轴流风扇之间的温度。考虑到室外换热器的灰尘积聚点多聚积于翅片内，且轴流风扇的转轴处风量较小，吹风对该处的温度影响小，因而三个温度检测点分别设置于室外换热器的翅片表面、轴流风扇的转轴处以及室外换热器的翅片表面与轴流风扇的转轴之间的中间位置，这样利用这三个温度检测点检测获得权重环境温度，该权重环境温度的大小直接受制于室外换热器的灰尘堆积程度，能够更为准确地反映室外换热器整体的灰尘积聚程度。
可选地，计算获得第二环境温度、第三环境温度与第四环境温度的权重环境温度，包括：

其中，T为权重环境温度，

为第三环境温度权重系数，T 3为第三环境温度，
Figure PCTCN2021111452-appb-000004
为第四环境温度权重系数，T 4为第四环境温度。
在实际应用中，

且
Figure PCTCN2021111452-appb-000006
室外换热器的翅片表面与轴流风扇的转轴之间的中间位置处的温度既能比较准确地反映室外换热器灰尘积聚程度，而且温度波动范围相对较小，温度值较为稳定；轴流风扇的转轴处的风量最小，受吹风影响最小，温度值最为稳定；而室外换热器的翅片表面处的温度能够反映出室外换热器的灰尘积聚程度。因而按照上述方式设置第二环境温度、第三环境温度以及第四环境温度的权重系数，计算获得权重环境温度能够更为准确地反映室外换热器整体的灰尘积聚程度。
S102:根据环境温度与预设温度的比例关系，控制空调执行自清洁操作。
可选地，根据环境温度与预设温度的比例关系，控制空调执行自清洁操作，包括：计算环境温度与预设温度的比值；在比值处于第一预设比值范围的情况下，控制空调立即执行自清洁操作；在比值处于第二预设比值范围的情况下，提示自清洁信息，并基于接收到的自清洁控制指令执行自清洁操作。
预设温度可以是空调换热器完成一次自清洁后，在同等稳定运行条件下检测到的换热器与风扇之间的温度，例如空调在高风档制冷运行模式、中风档制冷运行模式或低风档制冷运行模式下检测到的换热器与风扇之间的温度。第一预设比值范围可以为[0，50％]，例如，0、20％、30％、40％、50％，第二预设比值范围可以为(50％，80 ％]，例如，60％、70％、80％。在环境温度与预设温度的比值处于第一预设比值范围时，表明存在换热器上灰尘积聚过多现象，立即执行自清洁操作以免对空调正常换热和用户生命健康造成较大影响；在环境温度与预设温度的比值处于第二预设比值范围时，表明存在换热器上积尘现象(但不会对空调正常换热和用户生命健康形成威胁)，发出自清洁提示信息，并在接收到用户基于自清洁提示信息发送的自清洁控制指令后执行自清洁操作，避免空调因执行自清洁操作而扰乱空调正常的制冷或制热运行，从而提高用户的使用体验。
在一些实际应用中，空调的过滤网上设置指示灯，用于提示换热器的积尘情况。在环境温度与预设温度的比值处于第一预设比值范围时，指示灯以红色闪烁，提示用户换热器积尘严重；在环境温度与预设温度的比值处于第二预设比值范围时，指示灯以黄色闪烁，提示用户换热器存在积尘；否则，指示灯绿色常亮，提示用户换热器不存在积尘。这样，有助于用户更好地了解换热器的积尘状况。
采用本公开实施例提供的用于空调自清洁的控制方法，由于当空调的风扇转动时，如果换热器没有积聚灰尘，换热器可以很好地与外环境进行换热，换热器与风扇之间的环境温度相对较高，而当换热器积聚灰尘较多，换热器无法很好与外环境进行换热，换热器与风扇之间的环境温度相对较低，因此可以在空调稳定运行的情况下，获得空调的换热器与风扇之间的环境温度，并根据环境温度与预设温度的比例关系，控制空调执行自清洁操作，从而能够更好地确定启动空调自清洁的恰当时机，保证空调良好的制热或制冷调节，提高用户的使用体验。
在一些实施例中，用于空调自清洁的控制方法还包括按照如下方式确定空调稳定运行：控制空调按照预设运行模式运行；空调按照预设运行模式运行预设时长后，检测换热器表面的温度波动；在温度波动小于预设波动阈值的情况下，确定空调稳定运行。
预设运行模式是空调能够稳定运行的运行模式，在该运行模式下，热器与风扇之间的环境温度受外界环境影响较小，例如预设运行模式可以是高风档制冷运行模式、中风档制冷运行模式或低风档制冷运行模式。预设时长是一般情况下，空调从启动制热或制冷到环境温度达到目标温度的时长，例如可以是10min～20min(分钟)。空调在按照预设运行模式运行预设时长后，检测换热器表面的温度波动，在温度波动小于预设波动阈值的情况下，确定空调稳定运行。预设波动阈值的取值范围可以是[2℃，5℃]，例如，2℃(摄氏度)、3℃、4℃、5℃。
在一些实施例中，用于空调自清洁的控制方法还包括控制空调完成一次自清洁操作后，获得空调启动运行后的预设时段内换热器与风扇之间的环境温度变化率；根据环境温度变化率与预设温度变化率的大小关系，控制空调是否再次执行自清洁操作。
这里，预设温度变化率可以是前期试验过程中，当确认换热器无灰尘堆积时检测到的空调启动运行后的预设时段(例如启动后的5～10min)内换热器与风扇之间的环境温度变化率。在空调启动运行后的预设时段内，由于换热器灰尘堆积影响换热器换热系数的原因，空调换热器存在积尘时的换热器与风扇之间的环境温度变化率要小于空调换热器没有灰尘堆积时的换热器与风扇之间的环境温度变化率。因此根据环境温度变化率与预设温度变化率的大小关系，控制空调是否再次执行自清洁操作，以避免此次自清洁操作清洁不彻底。
可选地，根据环境温度变化率与预设温度变化率的大小关系，控制空调是否再次执行自清洁操作，包括：在环境温度变化率小于预设温度变化率的情况下，控制空调再次执行自清洁操作；在环境温度变化率大于或等于预设温度变化率的情况下，控制空调结束自清洁操作。
当环境温度变化率小于预设温度变化率时，表明换热器还存在积尘现象，此次自清洁操作不彻底，控制空调再次执行自清洁操作；当环境温度变化率大于或等于预设温度变化率时，表明换热器暂不存在积尘现象，此次自清洁操作较为彻底，控制空调结束自清洁操作。这样，能够提高空调自清洁操作的清洁程度。
结合图2所示，本公开实施例提供一种用于空调自清洁的控制方法，包括以下步骤：
S201：控制空调按照预设运行模式运行。
S202：空调按照预设运行模式运行预设时长后，检测换热器表面的温度波动。
S203：判断温度波动是否小于预设波动阈值。
S204：在温度波动大于或等于预设波动阈值的情况下，确定空调非稳定运行。

S206：在空调稳定运行的情况下，获得空调的换热器与风扇之间的环境温度。
S207：根据环境温度与预设温度的比例关系，控制空调执行自清洁操作。
S208：控制空调完成一次自清洁操作后，获得空调启动运行后的预设时段内换热器与风扇之间的环境温度变化率。

S210：在环境温度变化率小于预设温度变化率的情况下，控制空调再次执行自清洁操作。
S211：在环境温度变化率大于或等于预设温度变化率的情况下，控制空调结束自清洁操作。
