Description

一种空调器及其控制方法 技术领域
本发明涉及一种空气调节装置技术领域，特别涉及一种空调器及其控制方法。
 背景技术
现有空调室内机一般都有辅热功能,也就是在空调室内机内设置有电加热装置,用于辅助制热,加强空调制热效果。
一般电加热装置都是设置在室内机蒸发器附近。比如，挂机空调室内机的电加热装置一般安装在蒸发器与贯流风扇之间。当空调制冷运行时，室内空气通过空调内机进风口，经过蒸发器换热后成为冷风，一部分冷风会经过电加热装置后随着贯流风扇从出风口吹出。因此空调制冷时，电加热装置温度会快速降低。同时，由于空调制冷，在蒸发器翅片上会有很多冷凝水凝结，当空调结束制冷关机后，在实际测试中，风道内部空气中的湿度很高。因此，电加热装置在空调关机后，会在表面产生凝结水。夏季空调使用时，空调频繁开机使用制冷，会导致电加热装置处的凝结水越来越多，可能出现空调风速较高时，电加热装置上的冷凝水直接被吹出来，滴落到室内，影响用户空调使用体验。同时电加热装置上长期有冷凝水，存在一定安全隐患，可能导致电加热装置金属件氧化、锈蚀，缩短其使用寿命。还容易导致电加热装置处长期处于潮湿状态，形成霉变，导致空调吹出来的风有霉味。
另外，根据实际实验验证,空调在制冷运行的时候,由于电加热装置周围的温度场不均衡,同时内部湿度很高,在空调运行过程中电加热装置也会不断的产生凝结水,累积一段时间后就会直接滴落。
针对上述技术问题，现有解决方案：
1、空调结束制冷后短时间内进入送风模式，可以让电加热装置温度提高，降低电加热装置凝露可能。但是电加热温度提升有限，不能完全避免电加热装置上凝露的问题。
2、空调制冷运行时,通过遥控器/语音控制/APP等方式控制空调关机,空调内外风机及压缩机等按程序控制关闭,室内机导风板关闭后,内风机按设定好的低转速运转,同时电加热装置短时间开启，使电加热温度上升，将电加热装置上的凝结水蒸发干净。制冷结束后电加热开启加热使凝结水蒸发，但不能避免空调长期运行制冷时凝结水累积过多滴落的问题。
 技术问题
本发明的目的是要提供一种空调器及其控制方法，解决了现有空调器制冷或除湿运行时导致电加热装置周围温度不同，从而在电加热装置上产生冷凝水的技术问题。

 。本发明的实施方式
如图1-4所示，空调器包括位于壳体内在气流方向上依次排布的蒸发器1、电加热装置2和贯流风扇3。
在图1所示中，空调器制冷或除湿运行时，电加热装置2的上方空间、下方空间、左侧空间和右侧空间的温度并不一致。当电加热装置周围两个区域的检测温度出现以下情况时：电加热周围温度低的温度低于温度高的温度的露点温度，则会在两个温度区域之间出现水凝结，即在电加热装置上凝结冷凝水。在空调运行过程中电加热装置不断的产生凝结水,累积一段时间后就会直接滴落，随着贯流风扇直接吹出。
空调器运行时，不同的运行状态，例如，风速、导风板位置、压缩机运行频率（由环境温度和用户设定温度决定），导致电加热装置处于相同的角度时，电加热装置周围的温度分布情况不一致。
在空调器制冷或者除湿运行时，电加热的角度对电加热周围的温度场分布均匀情况非常重要，如果电加热装置处于一个使其周围的温度场分布不均的角度，容易在电加热装置2上产生凝露，而如果电加热装置处于一个使其周围的温度场分布均匀的角度，则电加热装置2上可避免产生凝露或者减小凝露的产生。因而，如何确定电加热装置的防凝露位置，使其周围参数不满足凝露条件，是本发明的目的。
空调器包括电加热装置2和电加热驱动装置5，电加热驱动装置5用于驱动电加热装置2转动，以调节电加热装置2的角度。
空调器的电加热装置2通过电加热驱动装置5带动转动，其中，电加热装置2一般可转动的安装在安装支架或者是蒸发器1的管板上，电加热驱动装置5包括驱动电机，例如，步进电机，驱动电机驱动电加热装置2转动。驱动电机可直接驱动电加热装置2，或者通过齿轮驱动电加热装置2。
电加热驱动装置5一般驱动电加热装置2在转动范围内正向反向交替转动，也即，电加热驱动装置5驱动电加热装置2从初始角度正向转动至终止角度为电加热装置在转动范围内转动一圈，电加热驱动装置5驱动电加热装置2从终止角度反向转动至初始角度为电加热装置在转动范围内转动一圈。此种方式可避免电加热电线的缠绕。
空调器包括检测模块4和检测模块驱动装置6，电加热装置2的周围设置有检测模块4，检测模块驱动装置6用于驱动检测模块4绕电加热装置5转动。
检测模块4与电加热装置2有一定距离，用于检测电加热装置2周围的参数。
在一些实施例中，检测模块4一般安装在支架41上，支架41可设置为圆环形，支架41上设置有圆环形滑槽和沿滑槽滑动的滑轨42，检测模块4位于滑轨42上，滑轨42上具有齿条。检测模块驱动装置6包括驱动电机，例如，步进电机，驱动电机安装在支架41上。驱动电机通过齿轮与齿条配合驱动滑轨42滑动。
检测模块驱动装置6驱动检测模块4在转动范围内正向反向交替转动，也即，检测模块驱动装置6驱动检测模块4从初始角度正向转动至终止角度为检测模块在转动范围内转动一圈，检测模块驱动装置6驱动检测模块4从终止角度反向转动至初始角度为检测模块在转动范围内转动一圈。此种方式可避免检测模块电线的缠绕。
电加热装置的转动范围与检测模块的转动范围可以相同，也可不同。
为了降低成本，检测模块4仅设置有一个，也可实现本发明的目的。
下面通过具体实施例进行说明：
实施例
空调器包括：电加热装置、电加热驱动装置、检测模块、检测模块驱动装置和控制模块。
电加热驱动装置用于驱动电加热装置转动。
检测模块位于电加热装置的周围，用于检测电加热装置的周围的参数。
检测模块驱动装置，用于驱动检测模块绕电加热装置转动。
控制模块，用于在空调器制冷或除湿运行时，进行凝露条件检测：用于控制电加热驱动装置驱动电加热装置转动至若干角度Wj，用于在电加热装置位于每个角度Wj时，通过检测模块驱动装置驱动检测模块绕电加热装置转动，获取检测模块转动过程中检测的至少两个参数。其中，检测模块转动过程可以是连续转动或者定角度转动。
在电加热装置处于角度Wj时，检测模块驱动装置驱动检测模块绕电加热装置连续转动时，检测模块实时检测参数，形成参数曲线Xj，以提高温度分布情况检测的精确性。检测模块驱动装置驱动检测模块绕电加热装置定角度转动时，检测模块驱动装置驱动检测模块绕电加热装置转动至多个不同位置，检测模块在多个不同位置时检测相应位置的参数。
在一些实施例中，将电加热装置的转动角度范围分割成n个角度，单个角度大小为D，电加热装置在每个角度时，检测模块驱动装置驱动检测模块绕电加热装置转动，优选转动一圈，检测模块检测参数形成参数曲线。电加热驱动装置驱动电加热装置在每个角度短暂停顿。
如图1、4所示，本实施例以电加热装置的转动角度分割为12个为例进行说明：
电加热装置在W1角度时，检测模块检测的参数形成参数曲线X1；
电加热装置在W2角度时，检测模块检测的参数形成参数曲线X2；
…
电加热装置在Wj角度时，检测模块检测的参数形成参数曲线Xj；
…
电加热装置在W12角度时，检测模块检测的参数形成参数曲线X12。
当然，电加热角度分割的越多，防凝露角度确定的越精确，但是，计算也越为复杂。
控制模块用于在凝露条件检测完毕后进入凝露条件判断：用于确定若干电加热装置的角度Wj对应至少两个参数的最大值Tmaxj和最小值Tminj，用于计算最大值Tmaxj和最小值Tminj的差，用于确定最大值Tmaxj和最小值Tminj的差的最小值对应的电加热装置的角度Wj为防凝露角度，控制电加热驱动装置驱动电加热装置转动至防凝露角度。
控制模块用于在凝露条件检测中控制电加热驱动装置驱动电加热装置在初始角度至（180度-初始角度）转动范围内转动。如图4所示，电加热装置在0度-180度转动范围内的角度W1-W6与电加热装置在180度-360度转动范围内的角度W7-W12完全相同，没有必要重复计算，因而，仅需控制电加热装置在0度-180度转动范围内转动并在特定角度获取检测模块检测的参数形成参数曲线即可，可减少控制模块的计算量。控制模块用于在电加热装置位于每个角度Wj时，通过检测模块驱动装置驱动检测模块从初始角度转动至终止角度或者从终止角度转动至初始角度，在检测模块转动过程中检测模块实时检测参数形成参数曲线Xj，以便对电加热装置位于每个角度时的周围温度分布情况进行全面获取。
控制模块用于在电加热装置位于防凝露角度时，判断空调器的运行参数是否发生变化，用于在空调器的运行参数发生变化时，按照变化后的运行参数运行设定时间后再进行凝露条件检测。
其中，空调器的运行参数包括风速、导风板位置、压缩机运行频率（与用户设定温度、环境温度相关）等。
由于空调器运行参数发生变化，按照变化后的运行参数运行后，使得电加热装置周围的参数发生变化，为了避免产生凝露，进入凝露条件检测步骤后，重新确定电加热装置的防凝露角度，以确保电加热装置始终处于温度场均匀的防凝露角度。
本实施例在空调器制冷或者除湿时，首先进行凝露条件检测：控制电加热驱动装置驱动电加热装置在其转动范围内转动至若干角度Wj，对于每个角度Wj，检测模块驱动装置驱动检测模块绕电加热装置转动一圈，检测模块转动过程中检测至少两个参数，优选实时检测形成参数曲线Xj。参数曲线Xj体现了电加热装置在每个角度Wj时其周围的温度场分布情况，对电加热装置若干角度下其周围的温度场分布情况进行全面了解，有助于最佳防凝露角度的确定。控制模块在凝露条件检测完毕后，再进行凝露条件判断：确定若干电加热装置的角度Wj对应至少两个参数的最大值Tmaxj和最小值Tminj，用于计算最大值Tmaxj和最小值Tminj的差，通过最大值Tmaxj和最小值Tminj的差的大小体现电加热装置周围的温度场分布是否均匀，差值越小，温度场分布越均匀，电加热装置产生凝露的风险越小，因而，确定最大值Tmaxj和最小值Tminj的差的最小值对应的电加热装置的角度Wj为防凝露角度，控制电加热驱动装置驱动电加热装置转动至防凝露角度。本实施例找到的防凝露角度能够保证电加热周围温度场分布均匀，避免或减少电加热装置产生凝露。
空调器的控制方法为：
空调器制冷或除湿运行；
凝露条件检测步骤：控制电加热驱动装置驱动电加热装置转动至若干角度Wj，在电加热装置位于每个角度Wj时，检测模块驱动装置驱动检测模块绕电加热装置转动，获取检测模块转动过程中检测的至少两个参数；
凝露条件判断步骤：确定若干电加热装置的角度Wj对应至少两个参数的最大值Tmaxj和最小值Tminj，计算最大值Tmaxj和最小值Tminj的差，确定最大值Tmaxj和最小值Tminj的差的最小值对应的电加热装置的角度Wj为防凝露角度，电加热驱动装置驱动电加热装置转动至防凝露角度。
在空调器制冷或除湿运行时，控制电加热驱动装置驱动电加热装置在其转动范围内转动至若干角度Wj，对于每个角度Wj，检测模块驱动装置驱动检测模块绕电加热装置转动一圈，检测模块转动过程中检测至少两个参数，优选实时检测形成参数曲线Xj，电加热装置2处于特定角度时检测模块4转动检测的参数形成的参数曲线能够体现此时电加热装置2周围的温度场是否均匀，确定若干电加热装置的角度Wj对应的检测模块检测的参数的最大值Tmaxj和最小值Tminj，在最大值Tmaxj和最小值Tminj的差最小时，说明电加热装置2周围的温度场最均匀，因而，选取最大值Tmaxj和最小值Tminj的差的最小值对应的电加热装置的角度Wj为防凝露角度，并控制电加热装置转动至防凝露角度，可保证电加热装置周围温度场分布均匀，避免或减少电加热装置周围冷热风交替混合导致温度场不均匀，避免或减少电加热装置产生凝结水并滴落。
