Description

空调器及其控制方法 技术领域
本发明属于空调器技术领域，具体涉及一种空调器及其控制方法。
背景技术
随着人们生活水平的不断提高，人们对生活环境也提出了越来越高的要求。为了维持舒适的环境温度，空调器已经成为人们生活中必不可少的一种设备。近年来，技术人员为了进一步提高空调器的安全性能，几乎所有空调器都设置有自检功能，并且现有空调器通常都具有很多种自检的方式；作为一种常用的自检方式，现有空调器会通过检测某些运行参数值来判断空调器的运行情况，从而选择性地使空调器停止运行。
具体而言，当现有空调器检测出自身的某些运行参数值超出预设范围时就会立刻使空调器停止运行；这种控制方法虽然更有利于空调器的保护，但是，却没有很好地顾及用户体验。可以理解的是，在环境温度过低或过高而空调器又刚开机运行的情形下，空调器的很多运行参数都会超出预设范围；此刻，现有空调器都会强制性地停止运行，而在大部分情况下，其实只要空调器能够强制正常运行一段时间，这些运行参数就能够自动恢复正常，进而使得空调器的各项运行参数均能恢复正常。
