Description

空调器 技术领域
本发明属于空调器技术领域，具体提供一种空调器。
背景技术
空调器是目前常用的室内环境温度调节设备，其包括商用空调器和家用空调器，商用空调器多应用于写字楼和商场等商用建筑，家用空调器多应用于住宅等民用建筑，空调器能够通过制热来提高室内环境温度，还能够通过制冷来降低室内环境温度。当空调器执行制热模式时，室外温度一般在10℃以下，而室外换热器中部温度在0～1℃左右，室外换热器与室外的温差较小，导致室外换热器不易从外界获得热量，使得制热效果较差，尤其是当室外温度为-10℃以下时，室外换热器更是难以从外界获得充足的热量，使得制热效果更差，制热时间长。
现有的空调器中，变频空调器一般通过提高压缩机的工作频率来降低室外换热器的温度，以从外界获取更多热量来提高制热效果；定频空调器一般通过设置电辅热装置来提高制热效果。但是无论是变频空调器还是定频空调器，采用上述的方式虽然能提高制热效果，但是都会使得空调器的耗电量增加。
因此，本领域需要一种新的空调器来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有空调器在提高制热效果的同时会造成其耗电量大的问题，本发明提供了一种空调器，该空调器包括室内换热器、室外换热器、压缩机、第一换向阀、第二换向阀和集热构件，室内换热器、室外换热器和压缩机构成闭环的冷媒循环***，集热构件设置在压缩机上或者靠近压缩机设置，第一换向阀用于使空调器在制冷模式和制热模式之间切换，第二换向阀设置为能够在空调器执行制热模式时将集热构件从压缩机上收集的热量输送至室内换热器。
在上述空调器的优选技术方案中，第二换向阀包括第一通道口、第二通道口、第三通道口和第四通道口，第二换向阀设置为在空调器执行制冷模式时将第一通道口与第二通道口连通以及将第三通道口与第四通道口连通以使冷媒循环***中的冷媒不经过集热构件，第二换向阀还设置为在空调器执行制热模式时将第一通道口与第四通道口连通以及将第二通道口与第三通道口连通以使冷媒循环***中的冷媒经过集热构件。
在上述空调器的优选技术方案中，第一通道口与室外换热器连接，第二通道口与第一换向阀连接，第三通道口和第四通道口分别与集热构件的两端连接。
在上述空调器的优选技术方案中，集热构件套设在压缩机上。
在上述空调器的优选技术方案中，集热构件部分套设在压缩机上。
在上述空调器的优选技术方案中，集热构件全部套设在压缩机上。
在上述空调器的优选技术方案中，集热构件为换热管罩。
在上述空调器的优选技术方案中，换热管罩为换热铜管罩。
在上述空调器的优选技术方案中，集热构件为螺旋换热管。
在上述空调器的优选技术方案中，螺旋换热管为螺旋换热铜管。
本领域技术人员能够理解的是，在本发明的优选技术方案中，空调器中设置有第二换向阀和集热构件，第二换向阀能够在空调器执行制热模式时通过冷媒的流动将集热构件从压缩机上收集的热量输送至室内换热器，通过这样的设置，使得压缩机的热量可以被充分利用，从而实现通过压缩机的热量来提高空调器的制热效果，且不会造成空调器耗电量的增加，降低空调器的运行成本，提升用户体验。
进一步地，第二换向阀包括第一通道口、第二通道口、第三通道口和第四通道口，并且第二换向阀设置为在空调器执行制冷模式时将第一通道口与第二通道口连通以及将第三通道口与第四通道口连通以使冷媒循环***中的冷媒不经过集热构件，第二换向阀还设置为在空调 器执行制热模式时将第一通道口与第四通道口连通以及将第二通道口与第三通道口连通以使冷媒循环***中的冷媒经过集热构件，通过这样的设置，使得在空调器制热过程中压缩机的热量可以被用来提高室内机的制热效果，并且在空调器制冷过程中压缩机的热量不会输送到室内机而影响空调器的制冷效果，即，通过第二换向阀的设置能够实现在空调器制热时提高制热效果以及在空调器制冷时不影响制冷效果，从而满足用户的使用需求，进一步提升用户体验。
进一步地，集热构件套设在压缩机上，这样的设置一方面使得空调器的室外机内部结构紧凑以节省空间，有利于室外机的小型化，另一方面使得压缩机的热量不易散失至空气中，从而使得压缩机的热量被集热构件充分吸收。
进一步地，集热构件部分套设在压缩机上，通过这样的设置，当在压缩机周围没有足够空间使集热构件全部套设在压缩机上时，使得集热构件也能够套设在压缩机上，同时也使得室外机的内部空间得到合理利用。
进一步地，集热构件全部套设在压缩机上，通过这样的设置，使得集热构件的每一部分都距离压缩机较近，从而使得集热构件能够从压缩机收集到更多热量。
进一步地，集热构件为换热管罩，通过这样的设置，使得冷媒的吸热面积更大，能够吸收更多热量。
进一步地，集热构件为螺旋换热管，通过这样的设置，使得冷媒在压缩机附近流动的路程更长，能够吸收更多热量。

优选地，如图1和2所示，第二换向阀4包括第一通道口41、第二通道口42、第三通道口43和第四通道口44，图1和2中所示的结构均以第一换向阀3和第二换向阀4是四通阀为例，第二换向阀4设置为在空调器执行制冷模式时将第一通道口41与第二通道口42连通以及将第三通道口43与第四通道口44连通以使冷媒循环***中的冷媒不经过集热构件5，第二换向阀4还设置为在空调器执行制热模式时将第一通道口41与第四通道口44连通以及将第二通道口42与第三通道口43连通以使冷媒循环***中的冷媒经过集热构件5。优选地，第一通道口41与室外换热器1连接，第二通道口42与第一换向阀3连接，第三通道口43和第四通道口44分别与集热构件5的两端连接。
具体地，继续参见图1和2，空调器包括第一冷媒循环管6、第二冷媒循环管7、第三冷媒循环管8、第四冷媒循环管9和第五冷媒循环管10，第一冷媒循环管6的一端与第一通道口41连通，第一冷媒循环管6的另一端与室外换热器1连通，第二冷媒循环管7的一端与第二通道口42连通，第二冷媒循环管7的另一端与第一换向阀3连接，第三冷媒循环管8的一端与第三通道口43连通，第三冷媒循环管8的另一端与集热构件5的一端连通，第四冷媒循环管9的一端与第四通道口44连通，第四冷媒循环管9的另一端与集热构件5的另一端连通，第五冷媒循环管10的一端与压缩机2的通道口21连通，第五冷媒循环管10的另一端与第一换向阀3连接，空调器执行制冷模式时，第二换向阀4处于第一状态，在第一状态下第一通道口41与第二通道口42连通，第三通道口43与第四通道口44连通，第二冷媒循环管7与第五冷媒循环管10能够通过第一换向阀3连通，空调器 执行制热模式时，第二换向阀4处于第二状态，在第二状态下第一通道口41与第四通道口44连通，第二通道口42与第三通道口43连通，第二冷媒循环管7与第五冷媒循环管10通过第一换向阀3断开。
空调器的控制器接收到制冷信号，第一换向阀3和第二换向阀4均动作(其中，第一换向阀3和第二换向阀4的动作次序不做限制)，使得空调器执行制冷模式，此时，如图1所示(图1的管路中箭头所指为冷媒在管路中的流动方向)，冷媒循环***处于第一连通状态，冷媒不流经集热构件5，具体地，冷媒从室外换热器1流至室内换热器，而后经第一换向阀3流入压缩机2，从压缩机2的通道口21流出后，依次经第一换向阀3、第二换向阀4的第二通道口42和第一通道口41流回至室外换热器1，即冷媒的流动路径为：室外换热器1→室内换热器→第一换向阀3→压缩机2→第一换向阀3→第二换向阀4→室外换热器1。
空调器的控制器接收到制热信号，第一换向阀3和第二换向阀4均动作(其中，第一换向阀3和第二换向阀4的动作次序不做限制)，使得空调器执行制热模式，此时，如图2所示(图2的管路中箭头所指为冷媒在管路中的流动方向)，冷媒循环***处于第二连通状态，冷媒流经集热构件5，在冷媒流经集热构件5时，通过集热构件5吸收压缩机2的热量，最终将从压缩机2吸收的热量释放至室内，具体地，冷媒从室外换热器1流出后，依次经第二换向阀4的第一通道口41、第四通道口44流至集热构件5，再从集热构件5流出，依次经第二换向阀4的第三通道口43、第二通道口42与第一换向阀3流至压缩机2，而后经第一换向阀3、室内换热器流回至室外换热器1，即冷媒的流动路径为：室外换热器1→第二换向阀4→集热构件5→第二换向阀4→第一换向阀3→压缩机2→第一换向阀3→室内换热器→室外换热器1。
优选地，集热构件5套设在压缩机2上，当然，本领域技术人员能够理解的是，可以是集热构件5部分套设在压缩机2上，也可以是集热构件5全部套设在压缩机2上(图1和2示出的正是这种情况)。
在一种可能的情形中，如图3所示，集热构件5为换热管罩，换热管罩包括第一柱形板51和第二柱形板52，压缩机2设置于所述第一柱形板51围成的柱形空间内，即换热管罩套设在压缩机2上，第一柱形板51和第二柱形板52之间形成有用于冷媒流经的环形空间，换热管罩包括进 口53和出口54，在空调器制冷时冷媒从进口53流入，经过该环形空间后从出口54流出。其中，本领域技术人员可以在实际应用中灵活地设置集热构件5与压缩机2之间的相对设置位置，只要能够实现冷媒从集热构件5中流过时能够通过集热构件5收集压缩机2上的热量即可。此外，第一柱形板51和第二柱形板52除图3中示出的截面形状(圆形)外，其截面形状还可以是正方形、长方形等其他形状；另外，进口53和出口54的设置位置除图3中示出的情况外，其设置位置也可以是其他形式，即，图3中示出的仅是换热管罩的一种可能的结构，不应解释为对本发明的限制。
优选地，换热管罩为换热铜管罩。
在另一种可能的情形中，如图1、2和4所示，集热构件5为螺旋换热管。螺旋换热管围绕压缩机2螺旋上升，即压缩机2设置于螺旋换热管形成的柱形空间内，螺旋换热管套设在压缩机2上，螺旋换热管包括进口53和出口54，冷媒从进口53流入，从出口54流出。其中，进口53和出口54的设置位置除图4中示出的情况外，其设置位置也可以是其他形式，即，图4中示出的仅是螺旋换热管的一种可能的结构，不应解释为对本发明的限制。
优选地，螺旋换热管为螺旋换热铜管。
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。
