Description
技术领域technical field
本发明涉及热水器技术领域，尤其涉及一种用户使用时无需排放用水管内的冷水，打开用水阀直接出热水的热水器。The invention relates to the technical field of water heaters, in particular to a water heater which can directly discharge hot water when a user opens a water valve without discharging cold water in a water pipe.
背景技术Background technique
普通的燃气热水器在使用的开始阶段，需将燃气热水器和出水管路中的冷水先放掉，才能正常使用热水。这样存在的问题是：1、造成水资源的浪费；2、不能直接流出热水，用水者需要等待。In the initial stage of use of ordinary gas water heaters, the cold water in the gas water heater and the water outlet pipeline needs to be drained before the hot water can be used normally. The problems that exist like this are: 1, cause the waste of water resource; 2, can not flow out hot water directly, the water user needs to wait.
针对上述问题科技工作者对现有的热水器提出了一些该进，如中国科学文献提供了一种节水节能燃气热水器，可缩短用于等待出水管内流出热水的时间，有利于节约水资源和燃气资源。该燃气热水器主要是在现有技术基础上设置预加热系统，该预加热系统包括用于对加热盘管加热的加热装置以及用于控制加热装置启闭的预加热系统开关。通过预加热系统可在出水管上的出水阀开启前，先对加热盘管内的水进行预加热，当出水阀开启后出水管可快速流出热水，显著缩短用于等待热水流出的时间，甚至可从出水管直接流出热水，有利于节约水资源和燃气资源。此外还可通过设置储水箱，水压指示装置等来提高预加热系统使用的安全性。In view of the problems referred to above, scientific and technological workers have proposed some advances to existing water heaters. A kind of water-saving and energy-saving gas water heater is provided as Chinese scientific literature, which can shorten the time for waiting for hot water to flow out of the water outlet pipe, which is conducive to saving water resources and gas resources. The gas water heater is mainly provided with a preheating system based on the prior art, and the preheating system includes a heating device for heating the heating coil and a preheating system switch for controlling the opening and closing of the heating device. Through the preheating system, the water in the heating coil can be preheated before the outlet valve on the outlet pipe is opened. When the outlet valve is opened, the outlet pipe can quickly flow out hot water, which significantly shortens the time for waiting for hot water to flow out. Hot water can even flow directly from the water outlet pipe, which is conducive to saving water resources and gas resources. In addition, the safety of the preheating system can be improved by setting a water storage tank and a water pressure indicating device.
上述节能热水器通过预加热的方式对加热盘管内的水进行预加热，其可有效的缩短等待热水流出的时间，但是其对加热盘管内的水预加热的效率较低，且无法对加热温度进行精确的控制，也就是说上述热水器并未从根本上解决水资源浪费和用户需要等待的问题，仅是缩短了用户等待的时间。The above-mentioned energy-saving water heater preheats the water in the heating coil by preheating, which can effectively shorten the time waiting for hot water to flow out, but its efficiency in preheating the water in the heating coil is low, and the heating temperature cannot be adjusted. Precise control means that the above-mentioned water heater does not fundamentally solve the problems of wasting water resources and users needing to wait, but only shortens the waiting time of users.
