Description

一种换热器和具有该换热器的洗衣机 技术领域
本发明属于洗衣机领域，具体地说，涉及一种换热器和具有该换热器的洗衣机。
背景技术
现有热泵干衣机，采用立式压缩机，压缩机、蒸发器、冷凝器放置在滚筒的底部:压缩机和换热器分列在左右两侧，蒸发器、冷凝器的体积大约各占底部空间的一半左右，受滚筒底部空间高度的限制，压缩机不能选择大容量的，蒸发器、冷凝器也无法有足够的除湿、加热面积，这导致热泵干衣机烘干时间偏长。
中国专利CN 201310251616.1公开了“一种热泵干衣机及干衣方法”热泵干衣机包括干衣滚筒、热泵系统及循环风系统，所述热泵系统包括压缩机、冷凝器、节流装置及蒸发器，至少所述冷凝器及蒸发器设置在所述干衣滚筒的后部。所述蒸发器位于冷凝器的下方，蒸发器的迎风面位于蒸发器的下方。
本发明用改变热泵位置的方式，解决了压缩机的空间问题，但这种方式并没有能够充分利用洗衣机内部的空间，虽然使压缩机的安装空间变大，但因为将冷凝器和蒸发器这些热泵循环装置安装到了滚筒的后部，这样在不改变滚筒容积的前提下仍然增加了洗衣机整体的外形尺寸。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种换热器和具有该换热器的洗衣机，充分利用洗衣机内壳体与滚筒外筒所包围的空间，在不增加现有洗衣机外形尺寸的情况下，增加了热泵系统的换热面积，提高干衣效率。
为了实现该目的，本发明采用如下技术方案：
一种换热器，应用于洗衣机，包括：蒸发器，冷凝器和风道，所述蒸发器和/或冷凝器截面具有独特形状，所述蒸发器和/或冷凝器位于滚筒外筒与壳体之间的空间中，所述蒸发器和/或冷凝器上接近滚筒外筒的一端的端面与其所接近的滚筒外筒的外围部分形状相配合。该换热器从所述蒸发器和/或冷凝器上与滚筒外筒相近的点到壳体的距离变化趋势，与所述点在相近的滚筒外筒上的投影点到壳体的距离变化趋势相同，所述投影点是所述点在所述距离方向上在相近的滚筒外筒上的投影。这种形状可以使换热器的外缘与滚筒外筒的形状相适应。
进一步地，所述蒸发器位于洗衣机的顶壳体、侧壳体及滚筒外桶所围成的空间内。
进一步地，所述冷凝器位于洗衣机的顶壳体、侧壳体及滚筒外桶所围成的空间内。
进一步地，所述蒸发器位于靠近滚筒背部一侧。
进一步地，所述蒸发器由至少一根微通道管构成，每根微通道管竖向连续折弯堆叠形成多个纵向排列部。
进一步地，所述冷凝器由至少一根微通道管构成，每根微通道管横向连续折弯堆叠形成多个横向排列部。
进一步地，所述微通道管的两相邻微通道管之间具有翅片，并且所述翅片具有开缝结构。
进一步地，所述蒸发器底部具有排水槽，所述排水槽通过连接管与滚筒的出风通道的位于蒸发器之前的部分连接。
进一步地，所述连接管还与洗衣机进水管相连。
另外还揭示了一种洗衣机，其具有以上任一所述特征的换热器。具有以上任意所述特征换热器的洗衣机，可以实现在同样的外观尺寸下更大的滚筒容积，并实现更好的干衣效果。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明所揭示的一种换热器，由弯折的微通道管组成，蒸发器和/或冷凝器截面具有独特形状，所述蒸发器和/或冷凝器位于滚筒外筒与壳体之间的空间中，所述蒸发器和/或冷凝器上接近滚筒外筒的一端的端面与其所接近的滚筒外筒的外围部分形状相配合。这种形状可以使换热器的外缘与滚筒外筒的形状相适应。
蒸发器和/或冷凝器放置于洗衣机顶壳体、侧壳体及滚筒外桶所围成的空间内，在不增加现有洗衣机外形尺寸的情况下，增加了热泵系统的换热面积，提高干衣效率。该空间在以往的设计中是空闲的空间并没有得到充分的利用。
本发明中的蒸发器多根微通道管构成，每根微通道管竖向连续折弯堆叠形成多个纵向排列部，两相邻微通道管之间具有翅片，并且所述翅片具有开缝结构。这样的设计，在增加了换热装置的接触面积，提高了换热效率的同时，还使蒸发器上的冷凝水在重力的作用下，可以通过开缝的翅片可以以更快的速度沿微通道管向下流动，从而冲刷蒸发器面板来减少线屑在蒸发器面上的堆积。同时所述冷凝器也可以由多根微通道管构成，每根微通道管横向连续折弯堆叠形成多个横向排列部。
从蒸发器流下的冷凝水通过放置于蒸发器底部具有排水槽，通过连接管引入到出风口的风道内，实现对风道内的空气进行预冷凝，增加了冷凝率的同时又可以利用它降低空气中的线屑含量。为了实现快速实现空气预冷凝的效果，还可以将冷的自来水通过该连接管引入到风道内，这样可以快速降低进入蒸发器的空气温度，降低压缩机负荷，使压缩机系统维持在一个安全运行的状态。
另外还揭示了一种洗衣机，其具有以上任一所述特征的换热器。具有以上任意所述特征换热器的洗衣机，可以实现在同样的外观尺寸下更大的滚筒容积，并实现更好的干衣效果。
下面结合附图对本发明的具体实施方式作进一步详细的描述。

如图1至图3所示，本发明揭示了一种换热器和具有该换热器的洗衣机，所述换热器应用于洗衣机，包括：蒸发器2，冷凝器8和风道5，所述蒸发器2和/或冷凝器8截面具有独特形状，所述蒸发器2和/或冷凝器8位于滚筒外筒6与壳体之间的空间中，所述蒸发器2和/或冷凝器8上接近滚筒外筒6的一端的端面与其所接近的滚筒外筒6的外围部分形状相配合。进一步描述就是从所述蒸发器2和/或冷凝器8上与滚筒外筒6相近的点到壳体的距离变化趋势，与所述点在相近的滚筒外筒6上的投影点到壳体的距离变化趋势相同，所述投影点是所述点在所述距离方向上在相近的滚筒外筒6上的投影，所述蒸发器2和/或冷凝器8位于洗衣机的顶壳体1、侧壳体7及滚筒外筒6所围成的空间内。
同时还揭示了具有该换热器的洗衣机。
实施例1：
如图1所示，本发明中蒸发器2的截面具有独特形状，所述蒸发器2位于滚筒外筒6与壳体之间的空间中，所述蒸发器2上接近滚筒外筒6的一端的端面与其所接近的滚筒外筒6的外围部分形状相配合。也就是从所述蒸发器2上与滚筒外筒6相近的点到壳体的距离变化趋势，与所述点在相近的滚筒外筒6上的投影点到壳体的距离变化趋势相同，所述投影点是所述点在所述距离方向上在相近的滚筒外筒6上的投影，所述蒸发器2位于洗衣机的顶壳体1、侧壳体7及滚筒外筒6所围成的空间内。
在以往的设计中由顶壳体1、侧壳体7及滚筒外筒6所围成的空间，由于形状并不规则，所以通常没有得到很到的利用，本发明中蒸发器2由多根微通道管构成，为了进一步增大换热器的接触面积，实施例中采用的是微通道扁管，每根微通道扁管竖向连续折弯堆叠形成多个纵向排列部，同时扁管的宽边迎着湿热空气流动的方向，利用微通道扁管从洗衣机壳体沿洗衣机宽度或高度方向按照离滚筒较近的方式折弯而成，以最大化利用滚筒与壳体间的空间，加工成的蒸发器2外廓呈大致梯形，或者为一边长度相同的梯形与矩形拼接形状。这样在满足足够的换热面积的同时，充分利用了这部分空间。同时两相邻微通道扁管之间还具有翅片，进一步增大蒸发器2与湿热空气的接触面积，达到了更好的换热效果。
同时，上述的翅片还具有开缝结构，使蒸发器2上的冷凝水在重力的作用下，可以通过 开缝的翅片可以以更快的速度沿微通道管向下流动，从而冲刷蒸发器2的面板减少线屑在蒸发器面2上的堆积。
实施例2：
如图2所示，本发明中冷凝器8的截面具有独特形状，所述冷凝器8位于滚筒外筒6与壳体之间的空间中，所述冷凝器8上接近滚筒外筒6的一端的端面与其所接近的滚筒外筒6的外围部分形状相配合。也就是从所述冷凝器8上与滚筒外筒6相近的点到壳体的距离变化趋势，与所述点在相近的滚筒外筒6上的投影点到壳体的距离变化趋势相同，所述投影点是所述点在所述距离方向上在相近的滚筒外筒6上的投影，所述冷凝器8位于洗衣机的顶壳体1、侧壳体7及滚筒外筒6所围成的空间内。
在以往的设计中由顶壳体1、侧壳体7及滚筒外筒6所围成的空间，由于形状并不规则，所以通常没有得到很到的利用，本发明中冷凝器8由多根微通道管构成，为了进一步增大换热器的接触面积，实施例中采用的是微通道扁管，每根微通道扁管横向连续折弯堆叠形成多个横向排列部，同时扁管的宽边迎着空气流动的方向，利用微通道管从洗衣机壳体沿洗衣机宽度或高度方向按照离滚筒较近的方式折弯而成，以最大化利用滚筒与壳体间的空间，加工成的冷凝器8外廓呈大致梯形，或者为一边长度相同的梯形与矩形拼接形状。这样在满足足够的换热面积的同时，充分利用了这部分空间。同时两相邻微通道扁管之间还具有翅片，进一步增大冷凝器8与湿冷空气的接触面积，达到了更好的换热效果。
实施例3：
如图1所示，蒸发器2流下来的冷凝水，除了可以起到冲刷蒸发器2的表面，避免线屑堆积之外的作用外，这部分冷凝水从蒸发器2流到放置于蒸发器2底部的排水槽3，通过连接管4引入到出风口的风道5内，这部分冷凝水可以实现对风道5内的湿热空气进行预冷凝。随着冷凝水在风道5中的滴落，不但降低了该风道内的湿热空气的温度，提高冷凝的效果，同时又可以降低空气中的线屑含量。
实施例4：
连接管4一端与进水管相连，另外一端与滚筒的出风风道5的位于蒸发器2之前的部分连接，这样可以将冷的自来水通过该连接管4引入到风道5内，快速降低进入蒸发器2的空气温度，降低压缩机负荷，使压缩机系统维持在一个安全运行的状态。
实施例5：
如图1，图2，图3所示，本发明中的洗衣机的顶壳体1、侧壳体7及滚筒外筒6所围成的空间内，放置有蒸发器2和冷凝器8，蒸发器2的位置与冷凝器8相比更靠近洗衣机的背部。
蒸发器2和/或冷凝器8截面具有独特形状，所述蒸发器2和/或冷凝器8位于滚筒外筒6与壳体之间的空间中，所述蒸发器2和/或冷凝器8上接近滚筒外筒6的一端的端面与其所接近的滚筒外筒6的外围部分形状相配合。进一步描述就是从所述蒸发器2和/或冷凝器8上与滚筒外筒6相近的点到壳体的距离变化趋势，与所述点在相近的滚筒外筒6上的投影点到壳体的距离变化趋势相同，所述投影点是所述点在所述距离方向上在相近的滚筒外筒6上的投影，所述蒸发器2和/或冷凝器8位于洗衣机的顶壳体1、侧壳体7及滚筒外筒6所围成的空间内。
本发明中蒸发器2由多根微通道管构成，每根微通道管竖向连续折弯堆叠形成多个纵向排列部，冷凝器8由多根微通道管构成，每根微通道管横向连续折弯堆叠形成多个横向排列部，为了进一步增大换热器的接触面积，实施例中采用的是微通道扁管，利用微通道扁管从洗衣机壳体沿洗衣机宽度或高度方向按照离滚筒较近的方式折弯而成，以最大化利用滚筒与壳体间的空间，加工成的蒸发器2和冷凝器8外廓呈大致梯形，或者为一边长度相同的梯形与矩形拼接形状。这样在满足足够的换热面积的同时，充分利用了这部分空间。同时扁管的宽边迎着空气流动的方向，两相邻微通道扁管之间还具有翅片，进一步增大蒸发器2和冷凝器8与空气的接触面积，达到了更好的换热效果。
同时，上述的翅片还具有开缝结构，使蒸发器2上的冷凝水在重力的作用下，可以通过开缝的翅片可以以更快的速度沿微通道管向下流动，从而冲刷蒸发器2的面板减少线屑在蒸发器面2上的堆积。
蒸发器2流下来的冷凝水，除了可以起到冲刷蒸发器2的表面，避免线屑堆积之外的作用外，这部分冷凝水从蒸发器2流到放置于蒸发器2底部的排水槽3，通过连接管4引入到出风口的风道5内，这部分冷凝水可以实现对风道5内的湿热空气进行预冷凝。随着冷凝水在风道5中的滴落，不但降低了该风道内的湿热空气的温度，提高冷凝的效果，同时又可以降低空气中的线屑含量。
当然为了实现更加快速的空气预冷凝效果，还可以将连接管4一端与进水管相连，另外一端与滚筒的出风风道5的位于蒸发器2之前的部分连接，这样可以将冷的自来水通过该连接管4引入到风道5内，快速降低进入蒸发器2的空气温度，降低压缩机负荷，使压缩机系 统维持在一个安全运行的状态。
可以看出，本发明充分利用了在以往的设计中被空闲掉的洗衣机内部空间，增加了热泵系统的换热面积，提高干衣效率，实现了在同样的外观尺寸下节省出更多的可用空间，这部分节省出的空间既可以用来为洗衣机增配更大功率的压缩机提高洗衣机整体的烘干效率，又可以为洗衣机实现其他有益效果而增配设备提供了空间。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
