Description

说 明 书 空调热水器 技术领域
本发明涉及家用电器领域， 具体涉及一种空调热水器。
背景技术
现有技术的空调器和热水器分属于两种产品， 空调器的主要功能是夏季提 供冷气， 改善人们的生活和工作环境， 空调器为制冷而排出的热风并未充分利 用， 造成资源浪费。
热水器有太阳能热水器、 电热水器和燃气热水器等， 其功能是向人们提供 热水。 最近已出现空气源热泵热水器， 其工作原理与空调非常相似， 应用了逆 卡诺原理， 通过吸收空气中大量的低温热能， 经过压缩机的压缩变为高温热能， 传递给水箱中， 把水加热起来， 整个过程是一种能量转移的过程， 即从空气中 转移到水中。 一般的空气源热泵热水器由主机和水箱构成， 主机需要置于室外， 运行时受环境影响较大， 一般仅适用于南方 （冬季温度 0度以上）地区， 并且 发明内容
为了解决上述空调器或热水器功能单一的问题， 本发明提供一种不受气候 和季节限制， 并且环保节能的空调热水两用的空调热水器。
为实现上述目的， 本发明采用如下技术方案：
一种空调热水器， 至少包括用于升高制冷剂压力的压缩机、 用于冷却经所 述压缩机压缩后的高温制冷剂气体并使之液化的冷凝器、 用于改变经所述冷凝 器液化后的制冷剂液体流量的节流元件、 用于加热使经所述冷凝器液化后的制 冷剂液体吸热蒸发为气体的蒸发器， 以及将所述压缩机、 冷凝器、 节流元件和 蒸发器依次连接的管道， 还包括一储水桶、 以及置于储水桶中的冷凝管路， 所 述冷凝管路与冷凝器并联， 冷凝器、 冷凝管路分别构成空调热水器的空调冷凝 支路和水加热支路。
优选地， 所述压缩机、 冷凝器、 节流元件和蒸发器均安装于室内， 构成一 体式空调结构； 所述冷凝管路与储水桶同样也安装于室内， 构成热水器结构， 所述热水器结构与一体式空调结构连接集成一体。
作为改进， 还包括与所述空调冷凝支路串联、 用于控制冷凝器工作与否的 第一控制元件， 以及与所述水加热支路串联、 用于控制冷凝管路工作于否的第 二控制元件。
优选地， 所述冷凝管路呈螺旋状。
作为进一步改进， 冷凝器和蒸发器处各设有一出风口， 所述出风口处分别 设有一转换器， 并且二个出风口同连接至一出风管道。
优选地， 所述转换器为方向控制阀， 转换器并置于出风管道中。
本发明所阐述的一种空调热水器， 与现有技术相比， 其有益效果在于： 本 发明采用冷凝管路与冷凝器并联， 冷凝管路并置于储水桶中， 从而实现热水和 空调两种功能， 将空调器和热水器合二为一， 在使用空调时， 利用冷凝热制取 热水， 可使水温保持在 55 °C左右， 作为生活热水使用， 不在向大气中排放废热； 不使用空调时， 吸收空气中的能量制取热水， 此时的用电量仅是普通电热水器 的 1/3~1/6。 另外本发明置有的第一控制元件和第二控制元件分别与冷凝器和冷 凝管路串联连接， 改变冷气和流动方向， 设置用途转换。
附图说明 附图 1为本发明空调热水器的结构框图；
附图 2为本发明出风管道的结构示意图。
具体实施方式
下面， 结合附图以及具体实施方式， 对本发明的空调热水器做进一步描述， 以便于更清楚的理解本发明所要求保护的技术思想。
为了克服分体式空调安装复杂的问题， 并为充分利用其排出的热风中的能 量， 本实施方式以一体式空调为基础， 增配一个储水桶， 储水桶内置有与空调 器的冷凝器并联连接的冷凝管路。
如图 1、 2所示， 本空调热水器安装在室内， 包括压缩机 1、 冷凝器 2、 节 流元件 5、 蒸发器 6, 压缩机 1将制冷剂压力升高后由冷凝器 2冷却经压缩机 1 压缩后的高温制冷剂气体并使之液化， 节流元件 5改变经冷凝器 2液化后的制 冷剂液体流量后由蒸发器 6加热使经所述冷凝器液化后的制冷剂液体吸热蒸发 为气体排向室内， 然后蒸发器 6连接至压缩机 1使整个系统循环， 压缩机 1、冷 凝器 2、 节流元件 5和蒸发器 6通过管道依次连接， 构成现有的一体式空调，为 实现空调、 热水两用功能， 在现有的一体式空调的基础上增加一带冷凝管路 4 的储水桶 3 , 冷凝管路 4呈螺旋状， 并与冷凝器 2呈并联连接， 即冷凝管路 4和 冷凝器 2的输入端均通过管道与压缩机 1的输出端连接，冷凝管路 4和冷凝器 2 的输出端均通过管道连接至节流元件 5 , 冷凝器 2、 冷凝管路 4分别构成空调热 水器的空调冷凝支路和水加热支路， 在空调冷凝支路和水加热支路中分别串联 一控制元件 7和控制元件 8,冷凝管路 4和冷凝器 2分别受控制元件 7和控制元 件 8的控制， 自动交替运行， 制取热水时不影响空调器的制冷效果， 此外， 空 调热水器中还安装有出风管道 10,出风管道 10分别与蒸发器 6的出风口以及冷 凝器 2的出风口连接， 并且出风管道可连接至室内， 也可以连接至室外， 转换 器 9为二个， 分别为安装于蒸发器 6的出风口的转换器 92和冷凝器 2的出风口 的转换器 91 , 转换器 91和转换器 92均置于出风管道中， 转换器 9可以选择采 用方向控制阀， 用于控制出风管道中的热气或冷气的流通方向 （排向室内或室 外）， 例如在转换器 9的管道通向控制下， 夏天需要制冷时将冷风吹向室内， 而 在冬天室内不需要冷气时， 将冷风排出到室外。
不需加热水时， 控制元件 7打开， 控制元件 8关闭， 冷凝管路 4不工作， 由冷凝器 2将热气通过出风管道在转换器 91控制下排向室外， 如图 2中箭头所 示将冷凝器 2输出的热气通过其出风口进入出风管道 10时由转化器 91控制向 上散发至室外， 蒸发器 6在转换器 92的控制下将冷气通过出风口散发室内， 如 图 2中箭头所示将蒸发器 6输出的冷气通过其出风口进入出风管道 10时由转化 器 92控制向上散发至室内， 供使用者享用。 排向室内的冷气和排向室外的热气 在各自的转换器的作用下在出风管道中互不影响。 此时就相当于普通空调的工 作状态。
在需要加热水时， 控制元件 7关闭， 控制元件 8打开， 冷凝管路 4工作， 压缩机 1将原本要排往室外的冷凝热排至储水桶 3 ,在冷凝管路 4的作用下热量 被水吸收， 达到所需温度后， 再排往室外。 同时， 蒸发器 6仍然制冷， 能作为 空调来工作。 当然， 如上所述在冬天室内不需冷气时， 只要通过转换器 92的控 制， 如图 2中箭头所示将蒸发器 6输出的冷气通过其出风口进入出风管道 10时 由转化器 92控制向下散发至室外， 将冷风排向室外， 即制取热水时不影响空调 器的制冷效果。 空调工作时产生的冷凝热被储水桶 3中的水吸收， 可使水温保 持在 55摄氏度左右，作为生活热水使用。 当然， 当水温达不到使用者的需求时， 可在储水桶 3中增设一电热器（图未示）。 此外， 控制元件 7和控制元件 8的打 开和关闭可以通过一个控制器进行控制。
对于本领域的技术人员来说， 可根据以上描述的技术方案以及构思， 做出 其它各种相应的改变以及变形， 而所有的这些改变以及变形都应该属于本发明 权利要求的保护范围之内。
