Automatic control pre-heating central water supply system of gas burning water heater

Abstract

The invention relates to a self-control preheating central water supply system for gas water heaters. The system mainly comprises a water heater main body, hot / cold water inlet / outlet pipes connected with the main body, and control valves arranged on the pipes. Two or more water consumption branches are connected on the hot water outlet pipe. The central water supply system is characterized in that: the water heater main body is also connected with a circulating device via pipes, a master controller and a flow meter are arranged inside the main body; the master controller is also connected with a remote manipulator, the circulating device is provided inside with a controller, a temperature-sensitive probe electrically connected with the controller, a water circulating pump and a flow meter, a one-way valve is arranged on the loop of the circulating device, the remoter manipulator, the master controller and the controllers are connected with one another by means of two-way non-polar safety voltage carrier waves, the main controller receives information from the controller of the circulating device and the remote manipulator and collects temperature and water flow data of the main body for further analysis and treatment, thereby forming the automatic control system of central water preheating. The system has the advantages of multiple functions, full-automatic intelligent control and good application effect.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas water heater with an automatic preheating control hot water supply system. Background technique [0002] At present, when using a water heater, after turning on the water supply valve and the combustion switch, it is necessary to wait for the combustion for a period of time until the water is heated to a suitable temperature before use. Cold water; digital constant temperature water heaters and their hot water supply systems on the market cannot achieve a good preheating effect in advance, and cannot achieve intelligent and humanized automatic control; in addition, safety protection such as anti-freeze protection needs to be strengthened. Contents of the invention [0003] The object of the present invention is to provide an intelligent and easy-to-use gas water heater to automatically control the preheating central water supply system in order to solve the defi...
