Description

一种用于实现除霜的方法、装置和空调室外机
本申请基于申请号为201910492243.4、申请日为2019年06月06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
本申请涉及空调技术领域,例如涉及一种用于实现除霜的方法、装置和空调室外机。
背景技术
目前,空调的除霜模式多是基于对空调连续运转时间和环境温度的检测,在空调的连续运转时间大于预设时间和环境温度小于预设温度的情况下,控制空调开启除霜模式。
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:
通过空调连续运转时间和环境温度判断空调是否开启除霜模式,不能有效判别空调是否结霜,常常会发生空调并没有结霜,而开启除霜模式的情况。
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实现除霜的方法、装置和空调室外机,以解决不能有效判别空调是否结霜,出现没有结霜却开启除霜模式的问题。
在一些实施例中,所述用于实现除霜的方法包括:
获取环境温度和空调的室外风机转速;
判断所述环境温度和所述室外风机转速是否满足除霜条件;
当满足所述除霜条件时,启动所述空调的除霜操作;
其中,所述除霜条件包括:所述环境温度低于温度阈值,并且所述室外风机转速低于转速阈值。
在一些实施例中,所述用于实现除霜的装置包括:
获取模块,被配置为获取环境温度和空调的室外风机转速;
判断模块,被配置为判断所述环境温度和空调的室外风机转速是否满足除霜条件;
控制模块,被配置为当满足除霜条件时,启动所述空调的除霜操作。
在一些实施例中,所述空调室外机包括上述的用于实现除霜的装置。
本公开实施例提供的用于实现除霜的方法、装置和空调室外机,可以实现以下技术效果:
在环境温度低于温度阈值时,空调室外机存在结霜的可能性,若空调室外机结霜,则冷凝器内部静压增大,室外风扇负载增大,导致室外风机转速降低,即,室外风机转速降低与空调室外机结霜具有直接联系。故,以环境温度是否低于温度阈值和室外风机转速是否低于转速阈值,作为判断室外机是否结霜的条件,可更加准确地判断出空调室外机是否结霜,即,更加准确地判断出是否满足除霜条件,进而在更加准确的时机启动空调的除霜操作,减少出现空调没有结霜,而开启除霜模式的情况。
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。

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。
本公开实施例提供了一种用于实现除霜的方法。
如图1所示,在一些实施例中,用于实现除霜的方法包括:
步骤S101、获取环境温度和空调的室外风机转速。
可选地,获取环境温度包括:通过设置在空调室外机上的温度传感器获取环境温度;或,通过有线网络或无线网络获取环境温度,例如,以有线或无线的形式在因特网中获取环境温度,或,以有线或无线的方式在局域网的服务器中获取环境温度;无线网络还可包括:蓝牙网络、WiFi(Wireless Fidelity,无线保真)网络、ZigBee(紫峰协议)网络中的 任意一个。
可选地,环境温度包括:空调室外机周围的环境温度、空调室外机回风口处温度中的任意一个。
可选地,获取室外风机转速包括:通过设置室外风机上的转速传感器获取室外风机转速,或,通过读取室外风机转速的给定值获取室外风机转速。
可选地,获取环境温度和空调的室外风机转速,包括:获取环境温度;当环境温度低于温度阈值时,控制室外风机连续运转一特定时间段;获取室外风机转速。
步骤S102、判断环境温度和室外风机转速是否满足除霜条件。
可选地,除霜条件包括:环境温度低于温度阈值,并且室外风机转速低于转速阈值。
上述温度阈值指的是空调室外机可能出现结霜现象时的温度,即,若环境温度低于温度阈值,则空调室外机存在结霜的可能性。例如,温度阈值小于等于可能使空调室外机出现结霜现象的环境温度的临界值。
上述转速阈值指的是空调室外机出现结霜现象,该结霜现象致使室外风机转速降低后所能达到的转速。在正常控制空调室外机的情况下,在室外风机转速低于转速阈值时,则说明存在影响风机转速的环境因素,在环境温度同时低于温度阈值时,则说明空调室外机有极大的可能性出现了结霜现象。
步骤S103、当满足除霜条件时,启动空调的除霜操作。
当满足除霜条件时,说明当前的环境温度低于温度阈值,当前的室外风机转速低于转速阈值。在环境温度低于温度阈值时,空调室外机存在结霜的可能性,若空调室外机结霜,则冷凝器内部静压增大,室外风扇负载增大,导致室外风机转速降低,即,室外风机转速降低与空调室外机结霜具有直接联系。故,以环境温度是否低于温度阈值和室外风机转速是否低于转速阈值,作为判断室外机是否结霜的条件,可更加准确地判断出空调室外机是否结霜,即,更加准确地判断出是否满足除霜条件,进而在更加准确的时机启动空调的除霜操作,减少出现空调没有结霜,而开启除霜模式的情况。
步骤S104、当不满足除霜条件时,控制空调正常运转。
步骤S103中,当满足除霜条件时启动空调的除霜操作的实现方式可以有多种。
如图2所示,在一些实施例中,S103中当满足除霜条件时启动空调的除霜操作,具体包括:
步骤S201、当环境温度低于温度阈值时,控制室外风机连续运转一特定时间段。
步骤S202、获取室外风机转速。
步骤S203、当室外风机转速低于转速阈值时,启动空调的除霜操作。
在环境温度低于温度阈值时,空调室外机存在结霜的可能性,结霜过程是一个缓慢的过程,若环境温度低于温度阈值的时间过短,则此时空调室外机未结霜或结霜不明显;在控制室外风机持续运转一特定时间段后,若空调室外机出现结霜现象,则室外机的结霜现象会比较明显,对室外风机转速的影响较大,此时再获取室外风机转速,容易获取准确的 判断结果,例如,若室外风机转速低于转速阈值,则空调室外机出现结霜现象的可能性比较高,从而可比较准确地判断出空调室外机出现结霜现象,启动空调的除霜操作实现有效除霜。
如图3所示,在一些实施例中,步骤S103中当满足除霜条件时,启动空调的除霜操作,具体包括:
步骤S301、当满足除霜条件时,对空调的结霜情况进行图像采集。
可选地,可通过设置在空调室外机上的摄像装置对空调的结霜情况进行采集。
步骤S302、获取结霜厚度。
可选地,获取结霜厚度包括:获取采集的图像的平均灰度,在数据库中检索出与该平均灰度对应结霜厚度。其中,灰度与结霜厚度之间的对应关系为:灰度越小,结霜厚度越厚。
步骤S303、当结霜厚度超过厚度阈值时,启动空调的除霜操作。
本实施例中,不仅判断环境温度和室外风机转速是否满足除霜条件,还进一步通过图像采集结霜厚度信息。在结霜厚度也超过厚度阈值后,再启动空调的除霜操作。这样,可进一步降低空调进入除霜操作的频率,有利于提高空调的能效,有利于维持室内环境温度的稳定性。
如图4所示,在一些实施例中,步骤S103中当满足除霜条件时,启动空调的除霜操作,具体包括:
步骤S401、当满足除霜条件时,采集电机的电流。
可选地,通过电流传感器采集电机的电流。
步骤S402、当电流超过电流阈值,启动空调的除霜操作。
其中,当电流超过电流阈值后,电机容易被烧毁。
本实施例中,不仅判断环境温度和室外风机转速是否满足除霜条件,还进一步采集电机的电流信息。空调室外机冷凝器外部结霜后,冷凝器内部静压增大,电机负载增大,电机电流增加。当电机电流增加到一定程度后,为了避免电机电流继续增加导致烧毁电机,控制风机降低转速。即,室外风机转速降低是由于风机电流升高,为了保护电机而抑制升高的电流导致的,通过检测室外风机的电流,可提高判断室外机是否结霜的准确性。
在一些实施例中,步骤S103中当满足除霜条件时启动空调的除霜操作,具体包括:
当环境温度低于温度阈值时,控制室外风机连续运转一特定时间段;
获取室外风机转速;
当室外风机转速低于转速阈值时,对空调的结霜情况进行图像采集并采集电机的电流;
当结霜厚度超过厚度阈值且电机的电流超过电流阈值时,启动空调的除霜操作。
