Description

用于空调器的自清洁控制方法及空调器 技术领域
本发明属于空调器技术领域，具体提供一种用于空调器的自清洁控制方法及空调器。
背景技术
空调器是能够为室内制冷/制热的设备，随着时间的推移，空调器的室内机和室外机上的积灰会逐渐增多，积灰累积到一定程度后会滋生大量的细菌，尤其在室内空气流经室内机时，会携带大量的灰尘和细菌，因此需要对空调器及时进行清洁。
现有技术中，空调器的清洁方式包括人工清洁和空调器自清洁，采用人工清洁较为费时费力，需要将空调器的各个零部件拆卸下来再进行清洁，清洁完成后还需要将各个零部件重新组装起来。因此，现在的许多空调器已经采用自清洁的方式，但是，受空调器实际安装位置、实际运行状态以及室内环境等因素的影响，空调器无法自动判断开启自清洁控制的时机，而是需要用户自行进行判断是否执行空调器的自清洁模式，这就会导致：如果频繁开启自清洁模式，虽然能够保证空调器的洁净度，但是会造成能源的浪费，如果经过很长的一段时间开启自清洁模式，则很难保证空调器的洁净度，并且可能会影响空调器的正常使用，同时影响人的健康。
因此，本领域需要一种新的用于空调器的自清洁控制方法及相应的空调器来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有空调器无法判断开启自清洁模式的时机的问题，本发明提供了一种用于空调器的自清洁控制方法，该空调器包括室内机，该自清洁控制方法包括：在当前状态下使空调器执行标准工况；获取室内机的盘管温度；根据室内机的盘管温度，判断是否执行自清洁模式。
在上述自清洁控制方法的优选技术方案中，空调器还包括室外机和压缩机，“根据室内机的盘管温度，判断是否执行自清洁模式”的步骤包括：判断室内机的盘管温度是否大于第一标准温度值；如果室内机的盘管温度大于 第一标准温度值，则进一步获取压缩机的排气温度和室外机的盘管温度中的至少一个；根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式。
在上述自清洁控制方法的优选技术方案中，“根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式”的步骤包括：如果压缩机的排气温度大于第二标准温度值，则执行自清洁模式；如果压缩机的排气温度不大于第二标准温度值，则进一步判断室外机的盘管温度是否大于第三标准温度值；如果室外机的盘管温度大于第三标准温度值，则执行自清洁模式；如果室外机的盘管温度不大于第三标准温度值，则不执行自清洁模式。
在上述自清洁控制方法的优选技术方案中，“根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式”的步骤包括：如果室外机的盘管温度大于第三标准温度值，则执行自清洁模式；如果室外机的盘管温度不大于第三标准温度值，则进一步判断压缩机的排气温度是否大于第二标准温度值；如果压缩机的排气温度大于第二标准温度值，则执行自清洁模式；如果压缩机的排气温度不大于第二标准温度值，则不执行自清洁模式。
在上述自清洁控制方法的优选技术方案中，“根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式”的步骤包括：判断压缩机的排气温度是否大于第二标准温度值并且室外机的盘管温度是否大于第三标准温度值；如果压缩机的排气温度大于第二标准温度值并且室外机的盘管温度大于第三标准温度值，则执行自清洁模式；如果压缩机的排气温度不大于第二标准温度值或者室外机的盘管温度不大于第三标准温度值，则不执行自清洁模式。
在上述自清洁控制方法的优选技术方案中，自清洁控制方法还包括：在清洁状态下使空调器执行标准工况；在标准工况下，测定第一标准温度值。
在上述自清洁控制方法的优选技术方案中，自清洁控制方法还包括：在清洁状态下使空调器执行标准工况；在标准工况下，测定第二标准温度值和第三标准温度值。
在上述自清洁控制方法的优选技术方案中，“根据室内机的盘管温度，判断是否执行自清洁模式”的步骤还包括：如果“判断室内机的盘管温度是 否大于第一标准温度值”的步骤的执行次数达到预设次数，则立即执行自清洁模式。
在上述自清洁控制方法的优选技术方案中，自清洁控制方法还包括：
如果空调器的运行时间达到预设时间，则立即执行自清洁模式。
在另一方面，本发明还提供了一种空调器，该空调器包括控制器，该控制器配置成能够执行上述的自清洁控制方法。
本领域技术人员能够理解的是，在本发明的优选技术方案中，在当前状态下使空调器强制执行标准工况，首先判断室内机的盘管温度是否过高，如果室内机的盘管温度不高，则不进行自清洁模式，如果室内机的盘管温度过高，则根据压缩机的排气温度和室外机的盘管温度中的至少一个来进一步判断是否进入自清洁模式。本发明的优选方案为：在满足室内机的盘管温度过高的前提下，如果压缩机的排气温度和室外机的盘管温度均过高，则立即执行自清洁模式，如果压缩机的排气温度或室外机的盘管温度不高，则不进行自清洁模式。通过这样的控制方式，可以使空调器根据室内机的盘管温度、压缩机的排气温度和室外机的盘管温度来判断进入自清洁模式的时机，从而实现空调器的自清洁，使空调器能够在合理的条件下执行自清洁模式，避免空调器频繁自清洁而浪费能源，同时避免空调器经过很长一段时间不自清洁而导致空气质量变差，影响人的健康。
进一步地，在上述控制方式的基础上，本发明还提供了另一种控制方式，即当“判断室内机的盘管温度是否大于第一标准温度值”的步骤的执行次数达到预设次数，空调器自动执行自清洁模式，通过这样的控制方式，使得在用于检测压缩机的排气温度的排气温度传感器和用于检测室外机的盘管温度的室外机盘管温度传感器均故障/损坏时，仍然可以通过计算“判断室内机的盘管温度是否大于第一标准温度值”的步骤的执行次数来判断进入自清洁模式的时机，从而使空调器能够根据第二种控制方式执行自清洁模式，避免空调器无法通过第一种控制方式执行自清洁模式而出现一直不执行自清洁模式的情况。
更进一步地，在上述两种控制方式的基础上，本发明更进一步地提供了通过空调器的运行时间是否达到预设时间来判断是否执行自清洁模式的控制方式，通过这样的控制方式，使得在用于检测室内机的盘管温 度的室内机盘管温度传感器、用于检测压缩机的排气温度的排气温度传感器和用于检测室外机的盘管温度的室外机盘管温度传感器均故障/损坏时，仍然可以通过空调器的运行时间来判断进入自清洁模式的时机，避免空调器无法通过第一种以及第二种控制方式执行自清洁模式而出现一直不执行自清洁模式的情况。
此外，本发明在上述技术方案的基础上进一步提供的空调器由于采用了上述的自清洁控制方法，因而具备上述自清洁控制方法的技术效果，并且相比于现有的空调器，本发明的空调器能够自动执行自清洁模式，并且能够避免空调器频繁自清洁而浪费能源，同时避免空调器经过很长一段时间不自清洁而导致空气质量变差，影响人的健康。

优选地，如图2步骤S202至步骤S216所示，“根据室内机的盘管温度，判断是否执行自清洁模式”的步骤包括：判断室内机的盘管温度是否大于第一标准温度值；如果室内机的盘管温度大于第一标准温度值，则进一步获取压缩机的排气温度和室外机的盘管温度中的至少一个；根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式；如果室内机的盘管温度不大于第一标准温度值，则不执行自清洁模式。需要说明的是，在本发明的技术描述中，“不执行自清洁模式”可以理解为不立即执行自清洁模式，即延时执行自清洁模式。其中，可以通过排气温度传感器来获取压缩机的排气温度，通过室外机盘管温度传感器来获取室外机的盘管温度。下面通过二个实施例来详细地阐述本发明的优选实施方式。
实施例一
如图2所示，“根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式”的步骤包括：判断压缩机的排气温度是否大于第二标准温度值(即判断压缩机的排气温度是否过高)并且室外机的盘管温度是否大于第三标准温度值(即判断室外机的盘管温度是否过高)；如果压缩机的排气温度大于第二标准温度值并且室外机的盘管温度大于第三标准温度值，则执行自清洁模式；如果压缩机的排气温度不大于第二标准温度值或者室外机的盘管温度不大于第三标准温度值，则不执行自清洁模式。其中，“判断压缩机的排气温度是否大于第二标准温度值”的步骤和“判断室外机的盘管温度是否大于第三标准温度值”的步骤可以先后进行，也可以同时进行，即在满足室内机的盘管温度大于第一标准温度值的前提下，可以先判断压缩机的排气温度再判断室外机的盘管温度(图2所示的正是这种判断步骤)，或者先判断室外机的盘管温度再判断压缩机的排气温度，再或者是同时判断压缩机的排气温度和室外机的盘管温度，当同时满足“压缩机的排气温度大于第二标准温度值”和“室外机的盘管温度大于第三标准温度值”两个条件时，空调器立即自动执行自清洁模式，否则，不执行自清洁模式。
实施例二
作为实施例一的另一种改变，除了可以同时满足“压缩机的排气温度大于第二标准温度值”和“室外机的盘管温度大于第三标准温度值” 两个条件才使空调器执行自清洁模式之外，还可以只满足“压缩机的排气温度大于第二标准温度值”和“室外机的盘管温度大于第三标准温度值”中的一个条件就可使空调器执行自清洁模式。具体而言，在一种可能的情形中，“根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式”的步骤包括：如果压缩机的排气温度大于第二标准温度值，则执行自清洁模式；如果压缩机的排气温度不大于第二标准温度值，则进一步判断室外机的盘管温度是否大于第三标准温度值；如果室外机的盘管温度大于第三标准温度值，则执行自清洁模式；如果室外机的盘管温度不大于第三标准温度值，则不执行自清洁模式。在另一种可能的情形中，“根据压缩机的排气温度和室外机的盘管温度中的至少一个，判断是否执行自清洁模式”的步骤包括：如果室外机的盘管温度大于第三标准温度值，则执行自清洁模式；如果室外机的盘管温度不大于第三标准温度值，则进一步判断压缩机的排气温度是否大于第二标准温度值；如果压缩机的排气温度大于第二标准温度值，则执行自清洁模式；如果压缩机的排气温度不大于第二标准温度值，则不执行自清洁模式。
总而言之，本领域技术人员可以在实际应用中灵活地设定空调器执行自清洁模式的条件，即可以在满足室内机的盘管温度大于第一标准温度值的前提下，“压缩机的排气温度大于第二标准温度值”和“室外机的盘管温度大于第三标准温度值”的两个条件其一满足或者是同时满足时，使空调器立即自动执行自清洁模式，这种控制方式的改变并不偏离本发明的原理和范围。
在本发明的实施方式中，为了准确地测定第一标准温度值、第二标准温度值和第三标准温度值。需要在清洁状态下使空调器执行标准工况；在标准工况下，测定第一标准温度值、第二标准温度值和第三标准温度值。需要说明的是，此处的“清洁状态”与前述的“当前状态”不同，“清洁状态”指的是能够确定空调器内无脏堵的状态，即已知空调器无脏堵，而“当前状态”指的是空调器的脏堵情况未知，因此，通过“当前状态”与“清洁状态”的比对，才能够判断空调器是否需要执行自清洁模式。具体而言，本发明的实现方式为：在未知脏堵情况的当前状态强制空调器执行标准工况，使其与已知无脏堵的清洁状态使空调运行标准工况进行比对，从而来判断当前状态下空调器有无脏堵。
此外，上述的“清洁状态”可以为空调器出厂前空调器处于无脏堵的状态，也可以为空调器刚完成自清洁/人工清洁确定无脏堵的状态，本领域技术人员可以在无脏堵的任何时刻对空调器进行标准测试。
优选地，第一标准温度值可以在空调器出厂前进行测定，即空调器处于完全清洁的状态下，其测定方式可以为将室外工况按照温度划分为几个区域，例如25℃以下，25至30℃，30至35℃，35至40℃和40℃以上。在实际应用中，可以固定压缩机的频率以及室内机的风速和室外机的风速，再设定温度为25℃，使空调器运行并在室内温度接近25℃(即可以偏差±1℃)且运行时间在20min以上时读取内盘管的温度范围值，从而得到该标准工况下的标准温度值。同样地，可以采用相同的方式读取25至30℃，30至35℃，35至40℃和40℃以上几个标准工况下的温度范围值。通过这样的方式，可以得出每个工况下的标准温度值，并且可以将上述各个工况下的标准温度值写入电脑板和/或后台数据中，从而便于空调器在出厂后运行时和标准温度值进行比对。同理地，采用上述的测试方法还可以得到每个工况下压缩机的排气温度的第二标准温度值和室外机的盘管温度的第三标准温度值。
此外，上述的第一标准温度值、第二标准温度值和第三标准温度值可以通过上述的实验方式测定，还可以通过本领域技术人员的经验获得，本领域技术人员可以在实际应用中采用各种方式灵活地获取第一标准温度值、第二标准温度值和第三标准温度值，只要通过第一标准温度值确定的分界点能够判断室内机的盘管温度是否过高，通过第二标准温度值确定的分界点能够判断压缩机的排气温度是否过高，通过第三标准温度值确定的分界点能够判断室外机的盘管温度是否过高即可。
优选地，“根据室内机的盘管温度，判断是否执行自清洁模式”的步骤还包括：如果“判断室内机的盘管温度是否大于第一标准温度值”的步骤的执行次数达到预设次数，则立即执行自清洁模式。其中，本领域技术人员可以通过实验的方式设定预设次数，也可以通过经验的方式设定预设次数，只要通过预设次数确定的分界点能够使空调器执行自清洁模式即可。例如，预设次数可以为5次，即在“判断室内机的盘管温度是否大于第一标准温度值”的步骤的执行次数达到5次时，空调器立即自动执行自清洁模式。
优选地，本发明的自清洁控制方法还包括：如果空调器的运行时间 达到预设时间，则立即执行自清洁模式。其中，本领域技术人员可以通过实验的方式设定预设时间，也可以通过经验的方式设定预设时间，只要通过预设时间确定的分界点能够使空调器执行自清洁模式即可。例如，预设时间可以为10h(小时)，即空调器的运行时间达到10h时，空调器立即自动执行自清洁模式。
参见图3，本发明还提供了一种空调器1，该空调器1包括控制器11，该控制器11配置成能够执行上述的自清洁控制方法
至此，已经结合附图所示的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。
