燃气热水器及其控制方法
摘要：
本发明公开了一种燃气热水器及其控制方法，该燃气热水器包括燃气主体、加热管路、进水管路、热水管路及冷水管路，加热管路设置在燃气主体上，进水管路经加热管路与热水管路连通，进水管路还经冷水管路与热水管路连通；燃气热水器还包括驱动管路、循环水泵及控制装置，驱动管路并联在进水管路上，循环水泵设置在驱动管路上，控制装置与循环水泵电连接；其中，控制装置，用于在接收到加热控制指令时，计时并启动循环水泵工作，以驱动加热管路、热水管路、冷水管路及进水管路内的水循环流动，在计时时间达到预设时长T时，控制循环水泵停止工作，并控制进水管路进水。本发明保证了用户能快速的用上热水，提高热水使用的便利性和及时性。
摘要（英）：

The invention discloses a fuel gas water heater and a control method thereof. The fuel gas water heater comprises a fuel gas body, a heating pipeline, a water inlet pipeline, a hot water pipeline and a cold water pipeline. The heating pipeline is arranged on the fuel gas body. The water inlet pipeline is communicated with the hot water pipeline through the heating pipeline. The water inlet pipeline is communicated with the hot water pipeline through the cold water pipeline. The fuel gas water heater further comprises a driving pipeline, a circulation water pump and a control device. The driving pipeline is connected to the water inlet pipeline in parallel. The circulation water pump is arranged on the driving pipeline. The control device is electrically connected with the circulation water pump. The control device is used for counting time and starting the circulation water pump to work when receiving a heating control instruction so as to drive water circulation flow inside the heating pipeline, the hot water pipeline, the cold water pipeline and the water inlet pipeline, when the counted time reaches preset time T, the circulation water pump is controlled to stop working, and water inlet of the water inlet pipeline is controlled. It is ensured that a user can rapidly use hot water, and the hot water using convenience and timeliness are improved.
