Energy-saving water-saving device of gas water heater with vacuum heat-preservation water tank

Abstract

An energy-saving water-saving device of a gas water heater with a vacuum heat-preservation water tank is formed by a gas water heater (6), a valve IV (4), a valve V (5) and a profibus onsite bus (16) and is characterized in that a central processing unit transmits control signals to control opening and closing of the valve IV (4) and the valve V (5) according to water level or water temperature requirements in a vacuum heat-preservation water tank (7) through the profibus onsite bus (16), determines cold water adding time and ignition heating time of the gas water heater, enables temperature of water input in the vacuum heat-preservation water tank to keep constant and cuts off water leakage of a water outlet pipe through an automatic locking valve III (3). By means of the automatic locking valve III, the vacuum heat-preservation water tank, the control panel, the central processing unit and the like, the energy-saving water-saving device of a gas water heater shortens waiting time of users in the using process of hot water, keeps water temperature at the user end constant, achieves the aim of saving energy and water and has actual application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of water heater automatic control. The utility model relates to a household gas water heater system, in particular to a gas water heater device with a vacuum insulation water tank which is energy-saving and water-saving and keeps water temperature constant. Background technique [0002] At present, most of the gas water heaters on the market are of the instantaneous type, that is, the cold water is heated in real time and used directly. Such water heaters are not convenient for keeping the outlet water temperature constant. In recent years, according to the market demand, gas water heaters have appeared to transform the heating tanks of water heaters to achieve stable water temperature, but it is difficult for such water heaters to achieve the purpose of energy saving and water saving. [0003] Usually, the household gas pipelines are installed in the kitchen. For easy installation and safe use, most gas w...
