Abstract

A forced exhaust preheating gas water heater, including a fan assembly, a heat exchanger assembly, a burner assembly, a water flow sensor, a proportional valve assembly and a control device, and also includes a solenoid valve water switch, a three-way switch valve , a hot water diversion pipe, a return pipe, a water pump and a temperature sensor, one end of the hot water diversion pipe is connected to the hot water outlet pipe, and the other end is communicated with one end of the straight pipe of the three-way switch valve, and the return pipe One end is connected to the solenoid valve water switch, and the other end of the return pipe is connected to the other end of the straight pipe of the three-way switch valve; the branch pipe outlet of the three-way switch valve is connected to the shower; On the water outlet pipe; the outlet end of the solenoid valve water switch and the outlet end of the water flow sensor are connected in parallel to the water inlet end of the water pump, and the water outlet end of the water pump is connected to the cold water inlet pipe. The water can be preheated to prevent water waste at the front end of the water heater.

Description

technical field [0001] The invention relates to a gas water heater. Background technique [0002] In the current prior art, a gas water heater with forced exhaust preheating includes a fan assembly, a heat exchanger assembly, a burner assembly, a water flow sensor, a proportional valve assembly and a control device. The upper part of the burner assembly, the burner assembly is arranged at the lower part of the heat exchanger assembly, and the proportional valve assembly communicates with the burner and the gas source of the burner assembly; the heat exchanger assembly includes a cold water inlet pipe and a heat exchanger assembly. The water outlet pipe and the water flow sensor are arranged on the cold water inlet pipe. Existing problem is: when using, can discharge with part cold water and can not directly be used for bathing, waste water source. Contents of the invention [0003] The object of the present invention is to provide a forced-discharge preheating gas water ...
