接着参阅图2,该图是本发明的清洁杀菌方法的优选实施例的步骤流程图。如图2所示,基于上述实施例中所述的空调器,本发明的清洁杀菌方法的优选实施例具体包括下列步骤:
S101:使导风板闭合;
S102:使室内换热器的表面温度维持在预设温度以上;
S103:经过第一预设时间后,使室内风机以预设转速反向转动第二预设时间;
S104:使室内换热器结霜;
S105:当室内换热器的结霜程度达到预设结霜程度时,使室内换热器化霜。
进一步地,在步骤S101中,所述控制器能够控制所述导风板闭合,以便封闭所述室内机的出风口,从而使得所述室内机的内部能够形成一个相对密闭的杀菌清洁空间,进而有效保证所述室内机的杀菌清洁效果。当然,步骤S101并不是必须设置的步骤,即在执行步骤S102之前,也可以不用执行步骤S101,即直接将步骤S102作为本方法的第一步骤即可。
进一步地,在步骤S102中,在所述导风板闭合以后,所述控制器能够控制所述室内换热器用作冷凝器,并通过所述主循环回路进行冷媒循环,同时通过所述室内换热器表面温度传感器检测所述室内换热器的表面温度,以便控制所述室内换热器的表面温度能够始终维持在所述预设温度以上,从而有效达到杀菌效果。需要说明的是,技术人员可以根据实际使用需求自行设定所述预设温度的具体数值;优选地,所述预设温度为60℃至70℃之间的任意值,以便有效保证所述室内机的杀菌效果。
进一步地,在步骤S103中,在所述室内换热器的表面温度维持在所述预设温度以上达所述第一预设时间后,所述控制器能够控制所述室内风机以所述预设转速反向转动所述第二预设时间;需要说明的是,技术人员可以根据实际使用需求自行设定所述第一预设时间的具体数值;优选地,所述第一预设时间为30min至40min之间的任意值,以便有效保证所述室内机的杀菌效果。此外,还需要说明的是,技术人员还可以根据实际使用需求自行设定所述预设转速和所述第二预设时间的具体数值,只要当所述室内风机以所述预设转速反向转动所述第二预设时间后能够将所述室内机的风道、风机和导风板上附着的灰尘、杂质和细菌残留物等吹至所述室内换热器的表面即可。
进一步地,在步骤S104中,在所述室内风机以所述预设转速反向转动所述第二预设时间后,所述控制器能够控制所述室内换热器用作蒸发器,并通过所述主循环回路进行冷媒循环,以使所述室内换热器的表面开始结霜;需要说明的是,技术人员可以根据所述空调器的不同结构以及所述空调器的使用区域自行设定所述空调器的运行参数,以使所述室内换热器的表面能够快速结霜。
进一步地,在步骤S105中,当所述室内换热器的结霜程度达到预设结霜程度时,例如,所述室内换热器的结霜厚度达到预设结霜厚度时,所述控制器则控制所述室内换热器进行化霜操作。需要说明的是,为了使所述室内换热器表面结的霜融化,所述控制器可以控制所述室内换热器再次作为冷凝器进行冷媒循环,当然,所述控制器也可以控制冷媒停止循环,从而使得所述室内换热器表面结的霜自然融化,本发明对此不作任何限制,只要所述室内换热器表面结的霜能够融化以清洁 所述室内换热器的表面即可。此外,本领域技术人员能够理解的是,本发明不对所述预设结霜程度的具体值作任何限制,技术人员可以根据实际清洁需求自行设定,并且技术人员既可以选用结霜厚度作为衡量所述室内换热器结霜程度的标准,也可以选用结霜面积作为衡量所述室内换热器结霜程度的标准,这些具体设定标准的改变并不偏离本发明的基本原理,属于本发明的保护范围。
最后需要说明的是,上述实施例均是本发明的优选实施方案,并不作为对本发明保护范围的限制。本领域技术人员在实际使用本发明时,可以根据需要适当添加或删减一部分步骤,或者调换不同步骤之间的顺序。这种改变并没有超出本发明的基本原理,属于本发明的保护范围。
至此,已经结合附图描述了本发明的优选实施方案,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。
