相关申请
本申请是以申请号为201810764808.5，申请日为2018年7月12日，发明名称为“一种空调外机的排水系统及包括该排水系统的空调”的中国专利申请为基础，并主张其优先权，该中国专利申请的公开内容在此作为整体引入本申请中。
技术领域
本公开涉及空调技术领域，更具体地说，涉及一种空调外机的排水系统及包括该排水系统的空调。
背景技术
空调内机在制热模式下，空调外机的换热器处于吸热状态，其温度低于外界气温，所以换热器上会出现冷凝水，冷凝水流下并在空调外机的底盘上不断积累，为了防止冷凝水对机器造成损害，需要将冷凝水排出。排出冷凝水的一种方式是通过水泵将冷凝水抽出。
但是，当换热器的温度低于0℃时，换热器上的冷凝水便结成冰，为保证空调制热模式的正常运行，空调需运行化冰化霜模式以将冰融化为冰水混合物落在空调外机的底盘上，并最终转化为水由水泵抽出。现有技术中，水泵固定安装在底盘上，水泵的吸水口与底盘之间保持固定的高度。若空调突然停止工作，且外界温度低于0℃，直接流下的冷凝水或化冰化霜模式下转化而来的水均会冻成冰，将水泵的叶轮冻结。或者，底盘上留存的雨水在室温低于0℃时转化而来的冰，也会冻结水泵的叶轮。这就导致空调机再次工作时，水泵将无法启动，甚至出现水泵卡死烧坏的情况。
因此，如何解决空调停机后，气温低于0℃时，外机底盘上的冰将水泵的叶轮冻结，导致水泵无法启动甚至被卡死烧坏的问题，成为本领域技术人员所要解决的重要技术问题。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将对本公开的技术方案进行详细的描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所得到的所有其它实施方式，都属于本公开所保护的范围。
本公开提供的实施例的目的在于提供一种空调外机的排水系统，解决空调停机后，气温低于0℃时，外机底盘上的冰将水泵的叶轮冻结，导致水泵无法启动甚至被卡死烧坏的问题。
以下，参照附图对实施例进行说明。此外，下面所示的实施例不对权利要求所记载的发明内容起任何限定作用。另外，下面实施例所表示的构成的全部内容不限于作为权利要求所记载的发明的解决方案所必需的。
请参考图1-图3，空调外机的排水系统包括水泵1和带动水泵1升降的升降装置，水泵1用于排出外机底盘的积水，水泵1在升降装置的带动下发生位移，使水泵1处于工作状态时，水泵1的吸水口2位于积水的液面以下，水泵1处于非工作状态时，水泵1的叶轮脱离积水。
如此设置，利于避免空调突然停机，且外界温度低于0℃的条件下，水泵1的叶轮位于积水的液面以下，致使水泵1的叶轮被冻结，水泵1无法启动甚至被卡死烧坏的现象出现。
在一些实施例中，排水系统还包括控制升降装置和水泵1的控制装置。在一些实施例中，控制装置用于控制水泵1失电时、控制升降装置带动水泵1上升，并且控制水泵1得电时、控制升降装置带动水泵1下降，也即水泵1失电的同时水泵1上升，水泵1得电的同时水泵1下降。
如此设置，方便对水泵1和升降装置进行控制操作，解决了空调停机致使水泵1失电、且外界环境温度低于0℃时，水泵1的叶轮被冻结的问题，也避免了水泵1处于得电状态时水泵1未下降，和水泵1上升后仍处于得电状态的情况发生，造成能源的浪费。
升降装置包括电磁铁组件3和复位组件，当电磁铁组件3得电时产生磁性，吸附水泵1产生位移，移动至第一位置；当电磁铁组件3失电时，复位组件带动水泵1移动至第二位置。水泵1位于第一位置和第二位置中的一个位置时，水泵1的吸水口2位于积水的液面以下，位于另一个位置时，水泵1的叶轮脱离积水。
也就是说，在一些实施例中，电磁铁组件3吸附水泵1移动至第一位置，水泵1的吸水口2位于积水的液面以下，复位组件带动水泵1移动至第二位置时，水泵1的叶轮脱离积水。当然，在其它实施例中，也可以为电磁铁组件3吸附水泵1移动至第二位置，水泵1的吸水口2位于积水的液面以下，复位组件带动水泵1移动至第一位置时，水泵1的叶轮脱离积水。
如此设置，水泵1在电磁铁组件3和复位组件的作用下，实现升降，使水泵1在工作时，水泵1的吸水口2位于积水的液面以下，水泵1在非工作状态时，水泵1的叶轮脱离积水。利于解决空调停机后，气温低于0℃时，外机底盘的冰将水泵1的叶轮冻结，导致水泵1无法启动甚至被卡死烧坏的问题。
在一些实施例中，复位组件包括弹性件4，电磁铁组件3得电时，水泵1在电磁铁组件3的吸附作用下发生位移，移动至第一位置，弹性件4发生弹性形变；电磁铁组件3失电时，电磁铁组件3对水泵1的吸附作用消失，弹性件4恢复形变，同时带动水泵1位移至第二位置。
如此设置，通过弹性件4实现水泵1位移至第二位置，结构简单，且能够实现在电磁铁组件3的磁性消失时，水泵1自动位移至第二位置。
在一些实施例中，电磁铁组件3吸附水泵1位移至第一位置时，水泵1的吸水口2位于积水的液面以下，水泵1在复位组件的带动下位移至第二位置时，水泵1的叶轮脱离积水。
如此设置，便于对电磁铁组件3和水泵1进行控制；而且，结构简单、设计合理，方便安装电磁铁组件3。
在一些实施例中，请参考图5-图6，排水系统还包括下支撑件6和上支撑件5，上支撑件5设置在下支撑件6上方，并且可以相对于下支撑件6上下移动。电磁铁组件3设置在下支撑件6上，当电磁铁组件3得电时能够吸附上支撑件5，使上支撑件5产生位移。水泵1设置在上支撑件5上，电磁铁吸附上支撑件5时，上支撑件5带动水泵1位移至第一位置。弹性件4的两端分别作用于上支撑件5和下支撑件6，水泵1位移至第一位置，弹性件4存在弹性形变，当电磁铁组件3失电时， 弹性件4恢复形变，带动下支撑件6相对于上支撑件5发生位移，上支撑件5带动水泵1位移至第二位置。
如此设置，通过上支撑件5和下支撑件6实现电磁铁组件3和水泵1之间的相互作用，使排水系统的结构更加稳定，更方便安装。
在一些实施例中，上支撑件5和/或下支撑件6包括横梁7和设置在横梁7两端的支腿8，电磁铁组件3设置在两个支腿8之间。在一些实施例中，上支撑件5和下支撑件6均包括横梁7和设置在横梁7两端的支腿8，并且上支撑件5和下支撑件6相对设置，电磁铁组件3位于下支撑件6的两个支腿8之间，当上支撑件5与下支撑件6相互靠近时，电磁铁组件3同时位于下支撑件6的两个支腿8之间，也即，电磁铁组件3位于上支撑件5的支腿8与下支撑件6的支腿8围成的空间内。
当然，在其它实施例中，也可以为上支撑件5和下支撑件6的二者之一包括横梁7和位于横梁7两端的支腿8，电磁铁组件3设置在两个支腿8之间。
如此设置，电磁铁组件3位于下支撑件6与上支撑件5之间的空间内，便于安装电磁铁组件3，结构设计更加合理，使排水系统的占用空间更小。
在一些实施例中，下支撑件6和上支撑件5之间设有导向柱9，上支撑件5在导向柱9的导向作用下沿竖直方向位移。如此设置，导向柱9能够提高排水系统结构的稳定性，防止上支撑件5在发生位移时出现左右晃动的情况。
弹性件4设置为环绕在导向柱9外周的弹簧，也即弹簧内穿设导向柱9，导向柱9穿过上支撑件5与下支撑件6固定连接。当然，弹性件4还可以为其它能够带动水泵1位移至第二位置的结构。如此设置，结构简单，且能够增加排水系统的稳定性。
在一些实施例中，上支撑件5的横梁7上固定设置有连接板10，水泵1与连接板10相连接，而且水泵1位于上支撑件5的边侧位置。如此设置，20水泵1在移动时，与上支撑件5的移动路径平行，能够避开排水系统的其它部件，比如，电磁铁组件3，防止水泵1在发生位移时与其它部件发生碰撞。
为了防止外机底盘的积水触及电磁铁组件3，下支撑件6的下方还设有支撑下支撑件6的基座11，下支撑件6通过基座11与外机底盘相连接。
在一些实施例中，基座11为拱形结构，并且下支撑件6设置在拱形结构的顶端位置。如此设置，由于拱形结构能够承起更大的重量，使排水系统的结构更加稳定，并且拱形结构占用空间更小，且减小了排水系统的重量。
在一些实施例中，上支撑件5与下支撑件6之间设有防止二者碰撞的缓冲垫13。缓冲垫13设置在下支撑件6的支腿8上，缓冲垫13的上端面不低于电磁铁组件3的上端面。如此设置，缓冲垫13对碰撞起到缓冲作用，防止上支撑件5与下支撑件6之间的冲击力过大，造成损坏，同时，缓冲垫13能够保护电磁铁组件3，防止上支撑件5碰撞电磁铁组件3。
在一些实施例中，空调外机为多联机空调的外机。当然，在其它实施例中，空调外机也可以为其它类型的空调的外机。
在一些实施例中，请参考图4，外机底盘还设有加热带12，加热带12能够使外机底盘的积冰融化为积水。空调在运行化冰化霜模式后，换热器上的冰融化为冰水混合物掉落在外机底盘上，或者空调在停机状态下，雨水在外界温度低于0℃时冻成冰，均可以通过加热带12将冰转化为积水，再由水泵1从外机底盘排出。
在一些实施例中，导向柱9设置为至少两个，电磁铁组件3包括至少两个电磁铁，在一些实施例中，两个电磁铁串联在一起。
水泵1的类型选择为离心泵，离心泵靠叶轮旋转时产生的离心力来输送液体，离心泵能适应零下30℃的环境、且功能不受影响，而且水泵1在工作时，叶轮与蜗壳之间一般没有摩擦力，能够增加水泵1的使用寿命。
当然，在其它实施例中，升降装置也可以为液压缸，通过液压缸带动水泵1在第一位置和第二位置之间产生位移，当水泵1位于第一位置和第二位置中的一个位置时，水泵1的吸水口2位于积水的液面以下，位于另一位置时，水泵1的叶轮脱离积水。
根据上述各个实施例对本排水系统进行具体说明，在一些实施例中，空调外机的排水系统包括排出外机底盘积水的水泵1、电磁铁组件3和弹簧，水泵1为离心泵。当电磁铁组件3得电时，吸附水泵1位移至第一位置，水泵1的吸水口2位于积水的液面以下，弹簧发生弹性形变；当电磁铁组件3失电时，弹簧恢复弹性形变，带动水泵1位移至第二位置，水泵1的叶轮脱离积水。
排水系统还包括控制装置，控制装置控制水泵1失电时、控制电磁铁组件3失电、此时水泵1在弹簧的带动作用下水泵1上升，并且控制水泵1得电时、控制电磁铁组件3得电、吸附水泵1下降。
排水系统还包括下支撑件6和上支撑件5，二者均包括横梁7和设置于横梁7两端的支腿8，上支撑件5和下支撑件6相对设置，电磁铁组件3位于支腿8之间、 与下支撑件6固定连接，上支撑件5和下支撑件6之间设有弹簧和导向柱9，弹簧环绕在导向柱9的外周，在电磁铁组件3的吸附作用下，上支撑件5可以相对于下支撑件6发生位移。水泵1通过连接板10与上支撑件5固定连接，并且水泵1位于上支撑件5的边侧位置。下支撑件6下方设有基座11，基座11为拱形结构、下支撑件6位于拱形结构的顶端位置。
上支撑件5和下支撑件6之间还设有防止二者碰撞、同时能够避免电磁铁组件3与上支撑件5发生碰撞的缓冲垫13。排水系统还包括对外机底盘的积冰加热的加热带12。
如此设置，电磁铁组件3得电的同时水泵1得电，水泵1在电磁铁组件3的吸附作用下下降，弹簧发生弹性形变，水泵1的吸水口2位于积水的液面以下，将外机底盘的积水排出；电磁铁失电的同时水泵1失电，弹簧恢复形变，水泵1在弹簧的作用下升高，水泵1的叶轮脱离积水。解决了空调停机后，气温低于0℃时，外机底盘的冰将水泵1的叶轮冻结，导致水泵1无法启动甚至被卡死烧坏的问题。
本公开一些实施例还提供了一种空调，包括上述的空调外机的排水系统。当空调停机时，水泵1的叶轮脱离积水。解决了空调停机后，气温低于0℃时，水泵1的叶轮被冻结，导致水泵1无法启动甚至被卡死烧坏的问题。该有益效果的推导过程与上述空调外机的排水系统所带来的有益效果的推导过程大体类似，故本文不再赘述。
可以理解的是，上述各实施例中相同或相似部分可以相互参考，在一些实施例中未详细说明的内容可以参见其他实施例中相同或相似的内容。本公开提供的多个方案包含本身的基本方案，相互独立，并不互相制约，但是其也可以在不冲突的情况下相互结合，达到多个效果共同实现。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
