本发明涉及移动式空调领域，具体提供一种移动式空调及其控制方法。
背景技术
相关技术中，移动空调短时间制冷制热切换，会产生大量冷凝水。分体式空调可以通过排水管将冷凝水直接排到室外。然而，由于移动空调内外机均装在同一外壳内且一般设于室内，无法通过排水管将冷凝水排到室外，因此，移动空调中会设有用于接冷凝水的接水槽，并通过水泵将接水槽内的水抽出。然而，移动空调长时间运行后，接水槽内会出现异物，异物会堵塞排水口、且导致接水槽的容量变低，甚至会影响水泵、打水电机的正常使用，存在改进空间。
中国专利(CN114353188A)公开了一种移动空调及其控制方法，其在一定程度上改善了接水槽存在异物的情况，需要进行清洁，在收到清洁指令之后打水电机开启最大转速之后，再开启水泵进行清洁排水。打水电机转速开至最大会导致接水槽内的水量减少，接水槽内的冷凝水增加的比较缓慢或者不再增加，无法达到有效的清洁。

具体实施方式
为了解决现有移动式空调的打水电机转速开至最大会导致接水槽内的水量减少，接水槽内的冷凝水增加的比较缓慢或者不再增加，无法达到有效的清洁的问题。
如图1所示，本实施例公开了一种移动式空调，移动式空调包括依次设置在冷媒回路上的压缩机、冷凝器200、膨胀元件和蒸发器100，移动式空调还包括下风机500、上风机300、水泵、接水槽400、打水电机、第一水位开关、第二水位开关、温度检测件和控制器。
其中，下风机500对应冷凝器200设置，用于对冷凝器200送风，具体使外部空气流经冷凝器200，调节冷凝器200的温度，主要是对冷凝器200进行散热。上风机300对应蒸发器100设置，其用于对蒸发器100送风，具体可以使外部空气流经蒸发器100，调节蒸发器100的温度。
下风机500与控制器电连接，控制能够控制下风机500的转速，压缩机与控制器电连接，控制器能够控制压缩机的运行频率，以对压缩机进行降频或升频。
接水槽400用于承接蒸发器100生成的冷凝水，水泵用于对 接水槽400排水，水泵与控制器电连接，控制器可以控制水泵的启停。
温度检测件设置在压缩机出口侧，用于检测压缩机的排气温度。温度检测件具体为温度传感器，在其它实施例中也可以温度计等，温度检测件与控制器电连接，可以将检测的压缩机排出的气体的温度反馈至传感器。
打水电机连接于接水槽400，用于将接水槽400内的水输送至冷凝器200处，以对冷凝器200进行散热。打水电机还用于搅拌接水槽400内的冷凝水。打水电机与控制器电连接，控制器用于控制打水电机的启停以及打水电机的转速。打水电机能够以第一预设打水转速、第二预设打水转速运转，且第二预设打水转速高于第一预设打水转速。第一预设打水转速为低转速，第二预设打水转速为高转速，打水电机在第一预设打水转速下运行时，对接水槽400内的水位影响较小，打水电机在第二预设打水转速运转时，可以更好地搅动接水槽400内的冷凝水。打水电机运转时随着接水槽400的水位变高，打水电机的运行阻力越来越大，打水电机的转速随着水位变高逐渐降低，功率逐渐升高。在水位最低时，其功率最低，为空转功率；在水位最高时，其功率最高，为高水位功率。打水电机上设置有功率检测装置，可以随时检测打水电机的功率。
如图2所示，本实施例还公开了一种移动式空调的控制方法，上述移动式空调的控制器能够执行上述的控制方法。该移动式空调的控制方法主要包括如下步骤：
S10、接收到清洁指令后；
S20、打水电机以第一预设打水转速运行；
S30、判断打水电机的功率水平；
S40、根据判断结果控制水泵和打水电机的运行。步骤S40具体包括如下详细步骤：
如果打水电机的功率达到高水位功率，则启动水泵，同时打水电机以第二预设打水转速运行，其中第二预设打水转速高于第一预设打水转速。
如果打水电机的功率未达到高水位功率，则执行增加冷凝水 的生成量的操作，直至打水电机的功率达到高水位功率。
启动水泵之后，如果打水电机达到了空转功率，关闭水泵。
启动水泵之后，如果打水电机未达到空转功率，水泵和打水电机保持当前状态运行。
如图3所示，该移动式空调控制方法具体包括如下详细步骤：
S1、移动空调制冷运行；
S2、当接收到清洁指令后，进行步骤S3；具体地，由控制器接收清洁指令。
S3、打水电机以第一预设打水转速运行。具体由控制器控制打水电机以第一预设打水转速运行，此时打水电机对接水槽400内的水位影响较小。
S4判断打水电机的功率是否达到了高水位功率，如果是，则进行步骤S5，如果否，则进行步骤S6。具体由控制器来判断打水电机的功率是否达到了高水位功率。随着水位的增加，打水电机的功率会逐渐增大，当水位到高水位时，打水电机的功率会升至高水位功率。
S5、启动水泵，打水电机以第二预设打水转速运行，然后进行步骤S7。其中，第二预设打水转速高于第一预设打水转速，打水电机可以搅动接水槽400内的水，使接水槽400内的污物同冷凝水被水泵一同排出。具体由控制器来控制水泵和打水电机的运转。
S6、获取压缩机的排气温度，然后根据压缩机的排气温度，控制压缩机的运行频率、下风机500的转速和上风机300的转速，以增加冷凝水的生成量，直至打水电机的功率达到高水位功率。
步骤S6具体包括：
S60、获取压缩机的排气温度之后，进行步骤S61。
S61、判断排气温度是否低于第一预设温度，如果是，则进行步骤S62，如果否，则进行步骤S63；具体由控制器来判断排气温度是否低于第一预设温度，第一预设温度具体可以为40℃-50℃，进一步地，第一预设温度可以为45℃。
S62、压缩机升频，且下风机500以第一预设转速运行，上 风机300以不低于第四预设转速的转速运行，然后进行步骤S4。其中，上风机300具体以第四预设转速运行，第四预设转速为低转速，第一预设转速为低转速。具体由控制器控制压缩机、上风机300和下风机500的运行。其中上风机300以低速运转，可以向蒸发器100送风，蒸发器100吸收所送的风的热量，使蒸发器100处产生冷凝水。此时排气温度并不高，冷凝器200温度也不高，冷凝器200不需要过度散热，这时下风机500以低转速运行，可以降低下风机500的功率，减少耗电量。下风机500运行可以对冷凝器200进行散热，防止冷凝器200产生的热量流至蒸发器100处，影响蒸发器100生成冷凝水。
S63、判断排气温度是否低于第二预设温度，如果是，则进行步骤S64，如果否，则进行步骤S65，其中第一预设温度小于第二预设温度。具体由控制器判断排气温度是否低于第二预设温度。第二预设温度可以为80℃-90℃，进一步地，第二预设温度可以为85℃。
S64、压缩机保持当前频率运行，下风机500以第二预设转速运行，上风机300以不低于第四预设转速的转速运行，然后进行步骤S4。其中，上风机300具体以第四预设转速运行，第二预设转速大于第一预设转速，第二预设转速为居中的转速。其中上风机300以低速运转，可以向蒸发器100送风，蒸发器100吸收所送的风的热量，使蒸发器100处产生冷凝水。此时排气温度不高不低，冷凝器200温度也不高不低，冷凝器200需要一定程度的散热，这时下风机500以居中转速运行，可以保证对冷凝器200的散热，也可以保证下风机500的功率不会过高，减少耗电量。下风机500运行可以对冷凝器200进行散热，防止冷凝器200产生的热量流至蒸发器100处，影响蒸发器100生成冷凝水。
S65、压缩机降频运行，下风机500以第三预设转速运行，上风机300以不低于第四预设转速的转速运行，然后进行步骤S4。其中，上风机300具体以第四预设转速运行，第三预设转速大于第二预设转速，第三预设转速为下风机500的高转速。其中上风机300以低速运转，可以向蒸发器100送风，蒸发器100吸收所送的风的热量，使蒸发器100处产生冷凝水。此时排气温度过高，为了保护压缩机，防止压缩机跳机，要对压缩机进行降频。排气温度过高，会导致冷凝器200温度过高，需 要对冷凝器200快速的散热，这时下风机500高速运行，可以快速地对冷凝器200散热，其可以防止冷凝器200产生的热量流至蒸发器100处，影响蒸发器100生成冷凝水。
S7、判断打水电机是否降到了空转功率，如果是，则进行步骤S8，如果否，则进行步骤S9。接水槽400内的水位降低之后，打水电机的功率会变小，当打水电机的功率降低至空转功率之后，代表接水槽400的水位到了低水位警戒线，需要关闭水泵。
S8、计时器开始计时，计时之后关闭水泵和打水电机。
S9、水泵和打水电机保持当前状态运行，然后进行步骤S7。
在开启水泵之前，打水电机先以第一预设打水转速运行，在打水电机的功率达到高水位功率之后，再启动水泵同时打水电机以第二预设打水转速运行，且第二预设打水转速大于第一预设打水转速。打水电机先以低速运行，不会将接水槽400冷凝水打出去，可以保证接水槽400内的冷凝水量不会减少，以便后续打开水泵进行有效地清洁。打水电机以第二预设打水转速运转，可以更好地搅动冷凝水，使接水槽400内的污物同冷凝水一同被水泵排出，可以达到有效的清洁。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，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。
