Description

一种除湿机
技术领域
本发明涉及暖通空调制造技术领域，具体来说，涉及一种除湿机。
背景技术
随着科技快速发展，除湿机应用越来越广泛。除湿机具备从空气中去除水分，从而降低空气湿度的功能。通常除湿机的工作原理是采用压缩机压缩制冷剂气体，压缩后的高温高压气体经过冷热交换器冷凝成为液体，液体制冷剂经过蒸发器时由液体吸热蒸发成气体，由于制冷剂蒸发过程会从空气中吸入大量的热量，导致空气湿度降低，当温度低于露点时，空气中的水分就会被冷凝下来，从而达到空气除湿的目的。
但是，就目前的除湿机技术而言，对除湿机的工作温度区间有着一定限制，一般是5°C~35°C的范围内，且在此范围内由于换热器中毛细管的限制，其除湿量和能效比不高，对除湿效果有明显的限制。
因此研制出一种除湿量和能效比较高、工作温度区间较宽的除湿机便成为业内人士亟需解决的问题。
发明内容
针对相关技术中的上述技术问题，本发明提出一种除湿机，能够提高除湿量和能效且扩大工作温度区间。
为实现上述技术目的，本发明的技术方案是这样实现的：
一种除湿机，包括风机、蒸发器、压缩机、四通换向阀、温湿度传感器及控制器，所述压缩机通过所述四通换向阀连接有冷热交换器，所述冷热交换器连接有电子膨胀阀，所述电子膨胀阀与所述蒸发器相连，所述风机、蒸发器、压缩机、四通换向阀、温湿度传感器、冷热交换器、电子膨胀阀均与所述控制器相连。
进一步地，所述除湿器下端设置有积水盘，所述积水盘下设置有水泵。
本发明的有益效果：
1.高能效，省电，美国能源之星是一级能效，在其他环境中也可以是最大化除湿量和能效比。
2.完全替代了毛细管，不需要毛细管。
3.程序里面编入了使用四通换向阀化霜程序，保证在最短的时间里可以快速化霜。根据不同的温度和湿度可以自动调节电子膨胀阀的流量，从而使机器得到最佳的除湿效果。
4.精确的湿度传感功能，能够准确的感知到环境的实际温度和湿度，并且根据不同的温度和湿度机器自动调节电子膨胀阀的流量，从而使机器得到最佳的除湿效果，也可根据调节电子膨胀阀的流量来达到造高温的环境中正常工作。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，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是根据本发明实施例所述的除湿机的结构示意图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本发明保护的范围。
为了方便理解本发明的上述技术方案，以下通过具体使用方式上对本发明的上述技术方案进行详细说明。
如图1所示，根据本发明实施例所述的一种除湿机，包括风机1、蒸发器、压缩机2、四通换向阀5、温湿度传感器8、控制器、冷热交换器3、电子膨胀阀4。
其具体工作原理为：开启机器，温湿度传感器8感知是否满足开机条件，若满足，电子膨胀阀4此时根据环境温度和湿度自动调节流量大小。风机1运行、压缩机2运行从蒸发器吸入低温低压制冷剂蒸汽，经压缩机2压成高温高压气体，经过四通换向阀5进入冷热交换器3，冷凝成液态，放出热量。再经电子膨胀阀4节流进入蒸发器，吸收空气热量，蒸发为气态通过回气管进入压缩机2。
其中，电子膨胀阀4可以进行流量调节工作，具体工作原理为：流量的大小取决于气态经过的管内经大小。而电子膨胀阀4有0～500步的开启，每开启或关闭一步都会增大或减少流量。再有控制器设定，在不同的温度和湿度情况下，电子膨胀阀4的开启流量大小均为理想化，从而使除湿量和能效比最大化。
对于不同的温度，除湿器可以进行调节，具体为：机器通电后，温湿度传感器8感知当前的温度和湿度的信号给控制器，再由控制器控制电子膨胀阀4的开启度，对于高温时（35～45度），电子膨胀阀4开启小点流量，确保机器不会因为功率过高而使其跳机保护。对于低温（1～5度）电子膨胀阀4开启大点流量，确保机器不会过冷而出现“液机”保护现象。从而使其使用温度范围大大的提升。
同时，本发明所述的除湿机可以进行快速有效的化霜，通常的机器都是自然风化霜或电磁阀化霜，化霜速度慢且有化不完现象。此化霜是通过四通换向阀5和电子膨胀阀4的双重结合进行化霜，其工作原理是：当机器进入化霜时四通换向阀5开始换向，即原高温高压气体进冷热交换器3，换向阀换向后，高温高压气体就进蒸发器，可以达到蒸发器快速加温，再通过电子膨胀阀4的流量控制，可使流量最大化，热量也可得到最大化，使其达到高效快速的化霜。
如图1所示，本发明所述除湿机，还包括积水盘6和水泵7，在实际使用时，一般除湿机中的制剂选择氟利昂。风机1转动吸进环境里的空气，湿度传感器感知是否启动或关闭机器，如果启动机器，压缩机2压出高温气态的氟利昂通过冷热交换器3，由冷热交换器3将高温气态的氟利昂转变成高温液态的氟利昂，然后氟利昂通过电子膨胀阀4转变成高温气态的氟利昂到达蒸发器，形成于环境湿度之间的差异，从而导致蒸发器表面水珠凝露，这些凝露落于积水盘6上，流向水泵7，水到达水位后，水泵7抽水，当环境湿度由于机器的运作，达到设定湿度时机器停止运行，湿度上升后又重新启动机器。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
