技术领域
本申请涉及空气温度调节技术领域，尤其涉及一种制热空调扇及控制方法。
背景技术
空调扇是一种全新概念的风扇，目前常见的空调扇为制冷型空调扇，空调扇内设置制冷装置，制冷装置对循环介质进行制冷，再将制冷后的循环介质导流至风扇处，风扇吹出冷风进行制冷；或者采用冰冻好的冰晶对储水箱的水进行降温，降温后的水汽经由风扇吹出，进行制冷。同时，制冷型空调扇也具有加湿空气的功能。空调扇相比于空调器而言，制冷功率低，价格低，受到越来越多用户的喜欢。
然而，目前制热功能的空调扇，多采用风扇直吹电加热器，在电加热器制热高温时多暴露在空气中，甚至于在湿度较大环境下制热时，进入的湿气容易对电加热器造成一定程度的氧化，降低电加热器的加热效率，严重的损害电加热器；并且现有直吹电加热器方式的制热空调扇，仅可在开启电加热的情况下进行制热，难以进行蓄热。

根据本申请提供的一种制热空调扇的控制方法，所述温度预设区间对应的温度值越大，所述开度信号对应的开度值越大。
根据本申请提供的一种制热空调扇的控制方法，在获取所述开度信号后，以第一预设时长为周期，每间隔第一预设时长，计算第一预设时长后室内环境温度值与第一预设时长前室内环境温度值的第二温度差值，判断所述第二温度差值是否大于第一预设温度值，若是，则维持所述节流阀开度；若否，则控制所述节流阀根据预设开度幅值调节开度。

本申请提供的制热空调扇及控制方法，通过设置导热管与散热管，并且导热管与散热管之间通过气管与液管连接形成循环管路，循环管路内设置冷媒，加热器加热循环管路内的冷媒进行制热，不再将加热器设置在通风通道中，加热器不受到湿气的影响，提高了电加热器的工作安全性。并且，本申请所述的空调扇可以与现有制冷型空调扇相结合，在空调扇吹出湿气时不会在电加热器上凝结出水露，能够防止电加热器损坏。并且散热管的设置也提高了空调扇有空气的接触面积，提高了热交换效率。

本实施例所述的制热空调扇，加热器300加热循环管路内的冷媒，尤其导热管200内的冷媒温度被加热。导热管200内的冷媒逐渐变高温而气化，气化的高温冷媒流通到散热管100中，并通过所述散热管100与空调扇风机吹动的风进行热交换，空调扇吹出热风，对周围环境进行制热。散热后的冷媒逐渐降温并冷凝，冷凝成液态的冷媒返回导热管200中进行加热，形成制热循环。
同时，本实施例所述的制热空调扇，在将液管500与气管400上的节流阀600关闭后，导热管200内处于相对封闭状态，使得所述空调扇具有 蓄热功能。并且，即便在制热空调扇未开机(用户未开启制热空调扇，制热空调扇风机不转动)的情况下，制热空调扇可在夜间用电谷值时间段内单独开启加热器300对导热管200内的冷媒进行加热，保温箱700能够有效的保持导热管200内冷媒的热量，待用户白天开启空调扇的制热功能时，空调扇可不开启加热器300，先将所述导热管200内的热量传输至散热管100处散出，实现一种夜间耗电而白天制热的节能制热空调扇。
并且，目前具有制热功能的空调扇，多采用风扇直吹电加热器的方式，使得电加热器制热高温时多暴露在空气中，甚至于在湿度较大环境下制热时，进入的湿气容易对电加热器造成一定程度的氧化，降低电加热器的加热效率，严重的损害电加热器。
本实施例所述的空调扇制热装置，通过设置导热管200与散热管100，并且导热管200与散热管100之间通过气管400与液管500连接形成循环管路，循环管路内设置冷媒，加热器300加热循环管路内的冷媒进行制热，不再将加热器设置在通风通道中，加热器不受到湿气的影响，提高了电加热器的工作安全性。
并且，本实施例所述的空调扇可以与现有制冷型空调扇相结合，在空调扇吹出湿气时不会在电加热器上凝结出水露，能够防止电加热器损坏。并且散热管100的设置也提高了空调扇有空气的接触面积，提高了热交换效率。
同时，导热管200不需要安装在通风通道内，具有一定的储热功能，能够确保冷媒以一定的高温条件持续一段时间，在关闭加热器300后的短时间内不会造成空调扇制热的中断。
进一步地，本实施例所述的制热空调扇还包括温度传感器，所述温度传感器用于检测所述导热管内冷媒温度。较好地，所述温度传感器设置在所述导热管200外壁上。
具体地，本实施例所述的加热器300，可为电加热器，包括电阻式电加热器、红外式电加热器与电磁式电加热器等。本实施例优选电阻式电加热器。如PTC电加热器，PTC加热器采用多个PTCR热敏陶瓷元件与波纹散热铝条经高温胶粘结组成，热阻小、切换效率高等优点。或者电热丝加热器，将电热丝缠绕在所述导热管200上，并在电热丝外侧包裹隔热层， 加热温度高，热传递效率大，加热快。
具体地，所述散热管100与所述导热管200有多种位置关系。优选地，所述导热管200位于所述散热管100下方，所述导热管200内加热的高温气态冷媒能够自然上升并通过所述气管400进入到所述散热管100中，所述散热管100冷凝后的冷媒也可在重力作用下流入所述导热管200中。
较好地，所述气管400和/或所述液管500倾斜设置。本实施例优选所述气管400与所述液管500均倾斜设置，能够防止所述气管400中上升的高温气态冷媒在所述气管400中冷凝出液态冷媒而向下流动，造成气态冷媒与液态冷媒的流动干涉，液态冷媒进一步降低上升的高温气态冷媒，严重的造成所述气管400堵塞而使得所述高温气态冷媒无法上升。
倾斜设置的所述气管400能够使得冷凝出的液态冷媒滑落回所述导热管200内，不会严重影响高温气态冷媒的温度，同时不会造成所述气管400堵塞。
较好地，所述气管400和/或所述液管500与水平面之间的倾斜角度小于70度，确保所述气管400和/或所述液管500具有一定的倾斜角度使得冷凝水顺着倾斜的管路流下。
需要说明的是，倾斜角度指的是所述气管400与水平面之间的最小夹角，以及所述液管500与水平面之间的最小夹角。
具体地，本实施例所述的气管400倾斜可有多种倾斜方式，当所述气管400为非直线形状时，凡是保证所述气管400内的流通管道与水平面之间为倾斜设置的，均落入本申请所限定的保护范围内。
需要说明的是，本实施例优选所述导热管200位于所述散热管100下方，在安装到空调扇内部时也与风道具有较好的匹配度。当空调扇结构设计需要所述散热管100与所述导热管200水平放置，或者所述散热管100位于所述导热管200上方时，在所述气管400上设置循环泵来驱动所述气管400中的气态冷媒流动。
较好地，所述散热管100和/或所述导热管200为盘管状。也就是说，散热管100为盘管状，或者导热管200为盘管状，或者本实施例中所述散热管100和所述导热管200均为盘管状，具体为翅片式盘管或微通道式盘管。
所述散热管100与所述导热管200的盘管结构可有多种，可以为螺旋式盘管，如所述导热管200呈螺旋式而缠绕在电加热棒的外侧，有利于所述加热器300加热所述导热管200；也可以为往复式盘管，如散热管100的盘管方式与现有空调蒸发器的盘管方式相同，有利于所述散热管100与空气之间进行热交换。
较好地，本实施例所述的制热空调扇，所述制热装置位于所述空调扇的壳体内，所述壳体内设通风通道，所述空调扇制热装置的散热管100位于所述通风通道内，所述通风通道内还设有风扇，所述风扇适于吹向所述散热管100，实现所述空调扇制热。
本实施例所述的空调扇，通过在空调扇内安装上述所述制热装置，所述制热装置通过设置导热管200与散热管100，并且导热管200与散热管100之间通过气管400与液管500连接形成循环管路，循环管路内设置冷媒，加热器300加热循环管路内的冷媒进行制热，不再将加热器设置在通风通道中，加热器不受到湿气的影响，提高了电加热器的工作安全性。
并且，本实施例所述的空调扇可以与现有制冷型空调扇相结合，在空调扇吹出湿气时不会在电加热器上凝结出水露，能够防止电加热器损坏。并且散热管100的设置也提高了空调扇有空气的接触面积，提高了热交换效率。
同时，导热管200不需要安装在通风通道内，具有一定的储热功能，能够确保冷媒以一定的高温条件持续一段时间，在关闭加热器300后的短时间内不会造成空调扇制热的中断。
进一步地，本实施例还提供一种用于控制上述任一实施方式所述的制热空调扇的控制方法，包括：
在接收空调扇开机指令后，开启节流阀，获取室内温度值，根据设定温度值与室内温度值控制所述节流阀的开度。
较好地，所述根据设定温度值与室内温度值控制所述节流阀的开度包括：
计算设定温度值与室内环境温度值的第一温度差值，确定所述第一温度差值落入的温度预设区间，获取落入的所述温度预设区间对应的开度信号，根据所述开度信号控制所述节流阀开度。
具体地，所述空调扇内预设多个温度预设区间，每个温度预设区间对应有不同的开度信号，不同的开度信号对应节流阀不同的开度值。
较好地，所述温度预设区间对应的温度值越大，所述开度信号对应的开度值越大。
例如，所述预设区间有四个B1、B2、B3与B4，B1为小于0℃(包括0℃)，对应开度值p1-20；B2为0℃到2℃(不包括0℃，包括2℃)，对应开度值p1；B3为2℃到5℃(不包括2℃，包括5℃)，对应开度值p1+20；B4为大于5℃(不包括5℃)，对应开度值p1+50。需要说明的是，开度值p1指的是空调扇制热过程中，节流阀开启p1开度值能够使得室内温度稳定在设定温度左右，具体数值以不同型号的空调扇，不同的冷媒而不同。
当判断结果为当前设定温度与室内环境温度的差值落入B4区间时，控制节流阀以p1+50的开度运行，使得导热管中的高温气态冷媒以较大的流通量进入散热管中，提高空调扇的制热效果。当判断结果为当前设定温度与室内环境温度的差值落入B2区间时，控制节流阀以p1的开度运行，使得导热管中的高温气态冷媒以相对较小的流通量进入散热管中，空调扇制热运行维持室内温度在设定温度左右。
在上述实施方式的基础上，在获取开度信号值后，每次间隔第一预设时长，计算第一预设时长后室内环境温度值与第一预设时长前室内环境温度值的第二温度差值，第二温度差值为第一预设时长后室内环境温度值与第一预设时长前室内环境温度值的差值，判断所述第二温度差值是否大于第一预设温度值T1，若是，则维持所述节流阀开度；若否，则获取预设开度幅值，控制所述节流阀开度根据所述预设开度幅值调节开度。
例如，在获取开度信号后，取第一预设时长为5min，每间隔5min，计算5min后室内环境温度值与5min前室内环境温度值的第二温度差值，判断所述第二温度差值是否大于第一预设温度值T1，第一预设温度值T1可以取3℃的定值，若第二温差差值大于3℃，表明空调扇制热效果明显，维持节流阀的开度值不变；若第二温差差值小于或等于3℃，表明空调扇制热效果不明显，需要增加节流阀开度值，在之前开度值的基础上，增加预设开度幅值，所述预设开度幅值可取定值20。
较好地，在上述实施方式的基础上，不同的温度预设区间对应不同的第一预设温度值T1，确定所述第一温度差值落入的温度预设区间后，获取落入的所述温度预设区间对应的第一预设温度值T1，所述温度预设区间对应的温度值越大，所述第一预设温度值T1越大。
例如，所述预设区间有四个B1、B2、B3与B4，B1为小于0℃(包括0℃)，对应开度值p1-20，第一预设时长为5min，对应第一预设温度值T1为-0.3℃；B2为0℃到2℃(不包括0℃，包括2℃)，对应开度值p1，第一预设时长为5min，对应第一预设温度值T1为0.3℃；B3为2℃到5℃(不包括2℃，包括5℃)，对应开度值p1+20，第一预设时长为5min，对应第一预设温度值T1为0.5℃；B4为大于5℃(不包括5℃)，对应开度值p1+50，第一预设时长为5min，对应第一预设温度值T1为0.8℃。
较好地，在上述实施方式的基础上，不同的温度预设区间对应不同的预设开度幅值，确定所述第一温度差值落入的温度预设区间后，获取落入的所述温度预设区间对应的预设开度幅值，所述温度预设区间对应的温度值越大，所述预设开度幅值越大。
例如，所述预设区间有四个B1、B2、B3与B4，B1为小于0℃(包括0℃)，对应开度值p1-20，第一预设时长为5min，对应第一预设温度值T1为-0.3℃，对应的预设开度幅值为-10；B2为0℃到2℃(不包括0℃，包括2℃)，对应开度值p1，第一预设时长为5min，对应第一预设温度值T1为0.3℃，对应的预设开度幅值为10；B3为2℃到5℃(不包括2℃，包括5℃)，对应开度值p1+20，第一预设时长为5min，对应第一预设温度值T1为0.5℃，对应的预设开度幅值为15；B4为大于5℃(不包括5℃)，对应开度值p1+50，第一预设时长为5min，对应第一预设温度值T1为0.8℃，对应的预设开度幅值为20。
较好地，在所述第一温度差值落入对应温度值最大的温度预设区间，并且节流阀增大至最大开度时，判断内管温度是否小于第五预设温度值，若是，则开启加热器；若否，则维持所述节流阀开度。
例如，当第一温度差值落入B4区间，随着节流阀开度的逐渐调整增大至节流阀的最大开度时，判断内管温度是否小于第五预设温度值，以检测内管温度是否达到制热需求。若内管温度小于第五预设温度值，表明内 管温度不足以进行制热，需要开启加热器进行制热；若内管温度大于或等于第五预设温度，则表明内管温度可以满足制热需求，维持节流阀当前的最大开度进行制热。
在节流阀开度增大至最大开度时，判断内管温度是否小于第五预设温度值，所述第五预设温度值为空调器内预设的蓄热模块释放热量处于较低水平的设定温度值，如35℃；当内管温度大于或等于第五预设温度值时，说明当前的节流阀开度下室内温度依旧能够提升，直至满足退出条件时退出加热控制；当内管温度小于第五预设温度值时，及时开启加热器进行加热，以确保制热量与制热速度满足用户需求。
较好地，本实施例还提供一种空调扇蓄热控制方法，结合图3所示，包括如下步骤：
步骤S100、在接收空调扇关机指令后，关闭节流阀；
步骤S200、进入蓄热控制程序。
具体地，所述蓄热控制程序包括：获取时间值，判断时间值是否落入预设低电时间区间，若是，则进入蓄热模式，所述蓄热模式包括开启加热器；若否，则等待第二预设时长后再次获取时间值，判断时间值是否落入所述预设低电时间区间，直至进入所述蓄热模式。
较好地，在进入所述蓄热模式后，实时获取时间值，当获取的时间值落入预设高电时间区间时，退出所述蓄热模式。
较好地，在蓄热模式中接收空调扇开机指令时，同样退出所述蓄热模式。
具体地，接收空调扇关机指令，指的是接收到用户通过遥控器或操控按钮发出的关机指令，空调扇在接收到关机指令后，关闭风扇与节流阀，使导热管处于封闭状态。
具体地，所述预设低电时间区间，指的是空调扇存储器中预设的用电谷值时间段。例如，某地区在凌晨零点至凌晨6点之间为用电谷值时间段，在凌晨零点至凌晨6点之间的6个小时电费较低，而在凌晨6点之后至第二天的凌晨零点之间的18个小时电费较高，因此可将凌晨零点至凌晨6点之间的6个小时时间段录入空调扇中，空调扇获取时间段信息并确定为预设低电时间区间。另外，预设高电时间区间指的是空调扇存储器中预设 的用电峰值时间段，如将凌晨6点之后至第二天的凌晨零点之间的18个小时时间段录入空调扇中确定为预设高电时间区间。
较好地，所述空调扇可设有时间设置程序，用户通过手机或遥控器录入；可选地，所述空调扇可通过物联网，通过获取定位信息后，通过物联网获取所在地区的用电谷值时间段与用电峰值时间段，并将获取的用电谷值时间段确定为预设低电时间区间，将获取的用电峰值时间段确定为预设高电时间区间，并能够实现自动更新。
本实施例所述的制热空调扇控制方法，在空调扇关机后，关闭节流阀，空调扇自动进入蓄热控制程序，通过时间来判断是否处于低电费的用电谷值时间段，在电费较低的时间开启加热器进行蓄热，以便于白天电费较高时先将导热管内蓄存的热量用于制热，再通过开启加热器进行制热，既能减少用户的用电消耗，减小用电费用，又能降低用电峰值时间段的用电量，提高地区用电的均匀性。
具体地，结合图4所示，所述蓄热模式中开启加热器的控制方法包括如下步骤：
步骤S210、获取内管温度值；
步骤S220、判断内管温度值是否小于第二预设温度值T2，若是，则开启加热器；若否，则间隔第三预设时长后再次获取内管温度值，判断内管温度值是否小于所述第二预设温度值T2，直至开启加热器。
具体地，所述第二预设温度值T2，指的是导热管内冷媒在预设低电时间区间内需要加热到的温度值，如用户通过遥控器或操作按钮进行选择的蓄热等级，不同蓄热等级对应不同的第二预设温度值T2。本步骤中，第二预设温度值T2为空调器预设的固定数值，如60℃
例如，用户选定的第二预设温度值T2为60℃，空调扇在进入蓄热模式后，获取内管温度值，判断获取的内管温度值是否小于60℃，小于60℃时控制加热器开启，进行蓄热；当内管温度值大于或等于60℃时，间隔30分钟后再次判断内管温度值是否小于60℃，循环判断至开启电加热。
较好地，开启加热器后，实时获取内管温度值，直至内管温度值达到大于或等于所述第四预设温度值T4，关闭加热器，并以第四预设时长为周期，间隔第四预设时长再次获取内管温度值，循环判断内管温度值是否 小于第四预设温度值T4，直至开启加热器。
本实施例中，所述第四预设温度值为空调扇蓄热模块最高温度值，如蓄热模块最高达到75℃，继续开启加热器则会对加热器及蓄热模块造成损坏。在开启加热器后，实时获取内管温度值并判断内管温度值是否增大到第四预设温度值T4，在达到第四预设温度值T4后及时关闭加热器，防止加热器加热温度超出用户制热的需求量。并且，在关闭加热器后，间隔第四预设时长后再次获取内管温度值，判断内管温度值是否小于第二预设温度值T2，直至开启加热器，实现一种自动温度监控，确保空调扇的内管温度值始终在第二预设温度值T2左右。
例如，用户选定的第二预设温度值T2为60℃，第四预设温度值T4为75℃，空调扇在进入蓄热模式后，获取蓄热模块温度值，判断获取的蓄热模块温度值是否小于60℃，小于60℃时控制加热器开启，进行蓄热；当蓄热模块温度值大于或等于75℃时，间隔30分钟后再次判断蓄热模块温度值是否小于60℃，循环判断至开启电加热。本实施例通过自主温度判断，在低于60℃时控制加热器开启，在温度达到75℃时控制加热器关闭，确保蓄热模块的温度始终保持在60℃至75℃之间。
较好地，本实施例所述的内管温度值为导热管中多个位置冷媒温度的平均值，如在导热管的两个端口与中间位置取3个位置的温度值，计算3个位置温度值的平均值确定为内管温度值，防止导热管内不同位置温度的不同而造成内管温度值的偏差，提高判断的准确程度。
较好地，在上述所述的制热空调扇控制方法中，即便是已经在运行所述蓄热控制程序，当接收到空调扇开启指令后，退出所述蓄热控制程序，进入加热程序。
本实施例以空调扇制热优先，将蓄热的控制优先级低于空调扇制热的优先级，以确保空调扇满足用户的制热需求量为准。
具体地，本实施例所述的加热程序，可参照目前已有的空调扇加热程序，依据用户设定的温度，确定内管需要加热的温度值，再控制加热器开启的时间与功率。
较好地，本实施例还提供一种加热程序的控制方法，结合图5所示，包括如下步骤：
步骤M100、开启节流阀；
步骤M200、获取内管温度值；
步骤M300、判断内管温度值是否小于第三预设温度值T3，若是，则开启加热器；若否，则间隔第五预设时长后再次获取内管温度值，判断内管温度值是否小于所述第三预设温度值T3，直至开启加热器。
具体地，在接收到用户发出的空调扇开启指令后，打开节流阀，使得所示导热管中的高温冷媒能够蒸发出高温蒸汽并流经到散热管中，实现空调扇的制热。开启节流阀后，获取内管温度值，较好地，内管温度值为导热管中多个位置冷媒温度的平均值；通过判断内管温度值是否小于第三预设温度值T3，确定是否开启加热器，并形成循环判断，在内管温度值小于第三预设温度值T3时及时开启电加热。
具体地，本实施例所述的第三预设温度值T3为导热管内冷媒蒸发出高温蒸汽的最低温度值，即在第三预设温度值T3以下时冷媒不再蒸发出高温气体，此时需要开启电加热来确保高温冷媒能够蒸发出气态冷媒。其中，第三预设温度值T3可依据冷媒特性来实验获得，并预设在空调扇的控制器内。
具体地，在开启加热器后，实时获取内管温度值，直至内管温度值达到大于或等于第四预设温度值时，关闭加热器。
本实施例所述的第四预设温度值，指的是导热管内冷媒能够加热到的最高温度。本实施例中，所述第四预设温度值为空调扇蓄热模块最高温度值，如蓄热模块最高达到75℃，继续开启加热器则会对加热器及蓄热模块造成损坏。
具体地，所述第四预设温度值大于所述第三预设温度值T3。
同样的，第四预设温度值可依据冷媒特性来实验获得，并预设在空调扇的控制器内。
本实施例通过设置第四预设温度值，防止加热器开启后造成冷媒温度过高而造成系统的不稳定，确保空调扇制热的正常运行。
需要说明的是，控制器可以包括：处理器(processor)、通信接口(Communications Interface)、存储器(memory)和通信总线，其中，处理器，通信接口，存储器通过通信总线完成相互间的通信。处理器可以调用存储 器中的逻辑指令，以执行空调器的空调扇控制方法。
