燃气热水器的温度控制系统技术方案

本发明专利技术公开了一种燃气热水器的温度控制系统，包括一热交换器、一冷水管、一热水管、一循环泵，该冷水管连接该热交换器一侧，该热水管连接该热交换器另一侧，该循环泵结合于一回水管，该回水管二端分别连接该热水管、该热交换器，用以将该热水管的热水输回到该热交换器。主要在于应用循环泵代替习用的混水阀和调节阀；当打开热水龙头使燃气热水器开启燃烧，循环泵持续通电将回水管不断循环回水进入热交换器，并且冷水管对热交换器输入冷水，使得回水、冷水于热交换器中混合进行预热，达到设定温度，温度控制稳定，不会温度过高或不足，热交换器温度始终与设定温度相同，且热交换器不会产生潜热；当关闭热水龙头使燃气热水器关闭燃烧，循环泵定期运转，藉动态水流流动以减少水垢的聚积。

Temperature control system of gas water heater

The invention discloses a temperature control system of a gas water heater, which comprises a heat exchanger, a cold water pipe, a hot water pipe and a circulating pump. The cold water pipe is connected with one side of the heat exchanger, the hot water pipe is connected with the other side of the heat exchanger, the circulating pump is connected with a return water pipe, and the two ends of the return water pipe are respectively connected with the hot water pipe and the heat exchanger, so as to make the hot water of the hot water pipe Back to the heat exchanger. It is mainly to use circulating pump instead of the conventional mixing valve and regulating valve; when the hot water tap is opened to make the gas water heater start burning, the circulating pump is continuously energized to continuously recycle the return water pipe into the heat exchanger, and the cold water pipe inputs cold water to the heat exchanger, so that the return water and cold water are mixed in the heat exchanger for preheating to reach the set temperature, and the temperature control is stable without temperature If the temperature is too high or insufficient, the temperature of the heat exchanger is always the same as the set temperature, and the heat exchanger will not generate latent heat; when the hot water tap is closed to make the gas water heater turn off combustion, the circulating pump operates regularly, and the accumulation of scale is reduced by dynamic water flow.

技术介绍
请参阅图3，现有的无水箱(Tankless)或所谓的混合(Hybrid)热水器(具有火管热交换器，Fire-tubeheatexchanger)构造上系于热交换器90二侧分别具有冷水管91、热水管92，冷水管91、热水管92之间连通有混水阀93(MixingValve)，冷水管91具有调节阀94(AdjustmentValve)，为了达到正确的热水设定温度，现有的热交换器90内的温度被设计成比设定温度更高(也就是比如说热水设定温度50℃，热交换器90的温度70℃)，并使用混水阀93(如步进马达控制阀，Steppingmotorcontrolvalve)，将热交换器90输出到热水管92之热水混合冷水管91的冷水达到准确的设定温度。请参阅图4，现有的一些热水器虽然配有泵(Pump)95，仍然必须要有一个二通阀(2-wayValve)96来控制温度，而泵95主要用于去除热交换器90燃烧本文档来自技高网...
