Abstract

The invention belongs to the technical field of water heaters, and particularly relates to a water-saving device of a water heater. The water-saving device comprises a water storage tank, a water inlet pipe for inputting cold water and a water outlet pipe for draining off hot water. A transverse pipe is arranged at the position, close to an outlet of the water outlet pipe, on the water outlet pipe and communicates with the water inlet pipe and the water outlet pipe. The transverse pipe is provided with a first solenoid valve and connected with a controller. A second solenoid valve is arranged at the position, higher than the transverse pipe, of the outlet of the water outlet pipe. A temperature sensor is arranged at the position, connected with the transverse pipe, of the water outlet pipe. The second solenoid valve and the temperature sensor are connected with the controller. The water outlet pipe communicates with a water change airbag in the horizontal direction. According to the water-saving device, a closed-loop control loop is formed through the temperature sensor and the controller, the first solenoid valve and the second solenoid valve are automatically controlled, the water change airbag is controlled manually, automatic control and manual control are combined, and operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of water heaters, in particular to a water-saving device for water heaters. Background technique [0002] Before the water heater is used normally, the cold water in the pipeline between the water heater and the water outlet nozzle needs to be drained to [0003] Let out the hot water. The amount of cold water discharged each time varies from several hundred milliliters to several liters, depending on the length of the pipe at the front of the water heater. Although not much cold water is consumed each time, since the water heater is an essential item for household use, the useless water consumption is quite huge, causing a great waste of water resources. [0004] At present, there are many inventions of storage devices or water-saving devices for the utilization of cold water at the outlet end of water heaters. some [0005] It adopts a cold water circulation pump, and is equipped with solenoid valves, ...
