Description

一种空气源即热式热水器 技术领域 本实用新型涉及一种热水器， 尤其涉及一种空气源即热式热水器。
背景技术 现有的即热式热水器都是以电能为能源， 将冷水通过大的电热装置在短时间内 加热成所设定的高温水， 这需要耗费大量的电能。 又由于加热前后的水流温差较大， 对热水 器的寿命也有比较大的影响。 而空气源热水器作为一种新型的家用设备， 能够有效的节省能 源， 但是空气源热水器对水的加热速度慢， 开机后等待时间长， 且其最高加热温度与空气源 热水器使用的工质性质以及外部环境温度有很大关系， 往往无法达到用户需要的高温。
发明内容 本实用新型的目的是提供一种节能、 高效的空气源即热式热水器。
为实现上述目的， 本实用新型包括即热式电加热装置， 即热式电加热装置上设有进水管 和出水管， 空气源加热装置的热水出口与即热式电加热装置的进水管相连通， 空气源加热装 置的冷水入口与自来水管相连通。 用户使用时， 水先被空气源加热装置加热到一定的温度， 再通过即热式电加热装置加热到更高的温度， 达到了用户的使用要求， 同时节省了能源。
本实用新型的空气源加热装置包括气体流动系统， 工质循环系统和水流管路系统； 所述 的气体流动系统包括吸入空气的进气端、 排出空气的排气端和用于驱动空气流动的轴流风扇; 所述的工质循环系统包括设于进气端的冷凝器和设于排气端的蒸发器， 所述的冷凝器和蒸发 器之间设有第一通路和第二通路， 工质循环系统中的工质由第一通路从蒸发器流向冷凝器， 第一通路上连接有压缩机， 工质由第二通路从冷凝器流向蒸发器， 第二通路上连接有膨胀阀， 工质循环系统中的工质在冷凝器和蒸发器之间循环流动； 所述的水流管路系统包括依序连接 的冷水入口、 热交换管路和热水出口， 冷水入口与自来水管相连通， 热水出口与即热式电加 热装置的进水管相连通， 所述的热交换管路与工质循环系统的冷凝器接触， 水流管路系统中 的水与工质循环系统中的工质发生热交换。
当轴流风扇开始运转后， 室外空气从进气端吸入空气源加热装置， 与蒸发器进行热交换， 温度降低后的空气被轴流风扇驱动从排气端排出空气源加热装置， 同时， 蒸发器中的工质吸 热汽化后被吸入压缩机， 压缩机将这种低压的工质气体压缩成高温、 高压的工质气体送入冷 凝器， 高温、 高压的工质气体在冷凝器中液化放热， 放出的热量传递给水流管路系统中的水， 这时水流管路系统中的水就会被加热， 而工质气体被冷却液化成工质液体， 该工质液体经膨 胀阀节流降温后再次流入蒸发器， 空气源加热装置不断进行上述循环而对冷水加热。
即热式电加热装置的进水管和出水管之间的管路上设有水流启动阀门。 水流启动阀门可 以感应管路中水的流动， 从而及时启动空气源加热装置和即热式电加热装置对水进行加温。 综上所述， 本实用新型与现有技术相比， 本实用新型先利用空气源加热装置提高水温， 再利用即热式电加热装置把水快速加热到用户需要的温度， 这样即节省了电能又达到了用户 的使用要求。
