技术领域
本申请涉及家用空调器的控制领域，尤其涉及一种防止空调过热的控制方法和装置。
背景技术
空调器在制热模式下运行，高温高压的制冷剂在室内蒸发散热将室内空气加热，实现空调制热的效果。
在空调制热运行过程中由于热空气会自动上升，在比较高位置悬挂的空调的上下摆风导板工作在上下摆动运行模式时，会出现热空气在房间上部聚集的现象。此时空调进风温度高，出风温度更高，如此循环会出现下述两个问题：
第一：由于空气在房间上部循环，用户体验不到制热效果。
第二：进风口温度过高会导致蒸发器温度过高，进而引发热保护，进一步的影响制热效果。
发明内容

附图说明
为了更清楚地说明本申请或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本申请提供的一种防止空调过热的控制方法的流程图；
图2是本申请提供的一种防止空调过热的控制方法的实际执行步骤示意图；
图3是本申请提供的一种防止空调过热的控制装置的结构图；
图4是本申请提供的实现防止空调过热的控制方法的电子设备结构示意图。
具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面结合图1至图4描述本申请提供的防止空调过热的控制方法和装置。
第一方面，本申请提供一种防止空调过热的控制方法，如图1所示，所述方法包括：
S11、空调进入制热模式之后，持续检测蒸发器温度；
可以理解的是，蒸发器温度，也叫内盘管温度，是利用蒸发器温度传感器测得的。
S12、当所述蒸发器温度不小于蒸发器热保护阈值时，基于上下摆风导板的运行模式对蒸发器进行降温控制。
需要注意的是，现在的空调制热开机，一般将上下摆风导板默认为制热下吹模式，但是用户还是可以根据需求调换到其它模式，例如：上下摆动运行模式和自设定下吹位置运行模式。在此情况下，蒸发器温度不小于蒸发器热保护阈值的现象，可能由空调上下摆风导板不处于制热下吹模式使得空调进风口温度过高导致，也可能由其它因素导致。因此，因此，本申请根据上下摆风导板的运行模式去针对性的进行蒸发器降温控制。
本申请提供的一种防止空调过热的控制方法，包括：空调进入制热模式之后，持续检测蒸发器温度；当所述蒸发器温度不小于蒸发器热保护阈值时，基于上下摆风导板的运行模式对蒸发器进行降温控制。本申请在空调蒸发器温度过高时，不直接对空调进行热保护，而是根据当前上下摆风导板的运行模式针对性的对蒸发器进行降温控制。通过这种方式尽可能减少热保护的触发次数，进而解决因触发热保护而导致的制热效果不佳的问题，最终达到提升用户使用体验的效果。
在上述各实施例的基础上，作为一种可选的实施例，所述基于上下摆风导板的运行模式对蒸发器进行降温控制，包括：
若所述上下摆风导板处于制热下吹运行模式，对空调进行热保护；
否则，将所述上下摆风导板的运行模式强制为制热下吹运行模式。
可以理解的是，若所述上下摆风导板处于制热下吹运行模式，说明蒸发器温度过高并非由于空调进风口温度过高导致，此时对空调进行热保护以保证空调的安全运行。若所述上下摆风导板的运行模式不处于制热下吹运行模式，说明蒸发器温度过高极有可能由于空调进风口温度过高导致，此时将所述上下摆风导板的运行模式强制为制热下吹运行模式，减少房间上部热空气含量，减小空调进风口温度，进而达到降低蒸发器温度的效果。
本申请在蒸发器温度过高且上下摆风导板运行状态不处于制热下吹模式的情况下，优先将上下摆风导板运行状态强制在制热下吹模式，在增强用户制热体验的同时降低空调进风口温度，以达到降温效果。
在上述各实施例的基础上，作为一种可选的实施例，所述将所述上下摆风导板的运行模式强制为制热下吹运行模式之后，还包括：
运行预设时长之后，判断此时蒸发器温度是否小于所述蒸发器热保护阈值；
若是，将所述上下摆风导板的运行模式恢复为强制之前的运行模式；
若否，对空调进行热保护。
可以理解的是，在预设时长之后蒸发器温度没有小于所述蒸发器热保护阈值，代表将上下摆风导板强制到制热下吹模式达不到预期降温效果，此时为安全起见进行热保护。在预设时长之后蒸发器温度小于所述蒸发器热保护阈值，代表将上下摆风导板强制到制热下吹模式能够实现有效降温，此时蒸发器温度已处于安全范围内，处于尊重用户的使用习惯的考虑，将上下摆风导板恢复到原来的运行模式。
本申请在一定程度上减少热保护的触发次数，尽可能规避了因热保护而导致的制热效果不佳的情况。
图2为防止空调过热的控制方法的实际执行步骤示意图，从图2中可看出，本申请具备以下实施步骤：
第一步：空调进入制热模式之后，检测蒸发器温度；
第二步：如果蒸发器温度不小于蒸发器热保护阈值，则判断上下摆风导板是否处于制热下吹运行模式；否则，返回第一步；
第三步：如果上下摆风导板处于制热下吹运行模式，则对空调进行热保护；如果上下摆风导板不处于制热下吹运行模式，则将上下摆风导板的运行模式强制为制热下吹运行模式；
第四步：将上下摆风导板的运行模式强制为制热下吹运行模式且运行预设时长之后，判断蒸发器温度是否小于蒸发器热保护阈值；
第五步：如果蒸发器温度小于蒸发器热保护阈值，则将上下摆风导板的运行模式恢复为强制之前的运行模式；如果蒸发器温度步小于蒸发器热保护阈值，则对空调进行热保护。
在上述各实施例的基础上，作为一种可选的实施例，所述热保护，包括：压缩机停机、压缩机降频、电子膨胀阀开阀和室外风机停机。
可以了解的是，压缩机停机、压缩机降频、电子膨胀阀开阀和室外风机停机是常见的几种热保护形式，其中：
压缩机停机：停止制热以使蒸发器温度降温；
压缩机降频：降低制热强度以使蒸发器温度降温；
电子膨胀阀开阀：开阀节流使压缩器排气，进而使蒸发器内部温度降低；
室外风机停机：室外换热变差，以使制热速率降低，进而使蒸发器温度降低。
本申请设定上述几种方式的热保护优先级降序顺序为室外风机停机、电子膨胀阀开阀、压缩机降频、压缩机停机。
在上述各实施例的基础上，作为一种可选的实施例，所述上下摆风导板的运行模式，包括：制热下吹运行模式、上下摆动运行模式和自设定下吹位置运行模式。
本领域内，大部分空调的上下摆风导板的运行模式包含上述几种。当然，也可以根据空调的机型酌情增减。
在上述各实施例的基础上，作为一种可选的实施例，所述蒸发器热保护阈值处于58℃到68℃范围内。
本实施例给定蒸发器热保护阈值比较普适的取值范围，实际应用时应根据运行工况来选定。
在上述各实施例的基础上，作为一种可选的实施例，所述预设时长为3分钟。
