Gas-fired water heater with water outlet at constant temperature and method for realizing constant temperature of water outlet

Abstract

The invention discloses a gas water heater with constant temperature outlet water and a method for realizing constant water outlet temperature. The gas water heater includes a heater, a water inlet pipe connected to the water inlet end of the heater, and a water outlet pipe connected to the water outlet end of the heater; An intermediate water storage pipe, one end of the intermediate water storage pipe is connected to the water outlet pipe of the heater through a first connection point, and the other end is connected to the water outlet pipe through a second connection point; In the direction of water flow in the water pipe, the first connection point, the first valve and the second connection point are sequentially arranged on the water outlet pipe; the end of the intermediate water storage pipe corresponding to the first connection point is provided with a second valve. After the hot water valve is opened again, the gas water heater can keep delivering hot water all the time, and there will be no "surprise" phenomenon of cold water, which greatly improves the comfort of bathing.

Description

technical field [0001] The invention relates to a heater, in particular to a gas water heater with water outlet at constant temperature and a method for realizing constant temperature of water outlet. Background technique [0002] A gas water heater, also known as a gas water heater, refers to a gas appliance that uses gas as a fuel to transfer heat to cold water flowing through a heat exchanger through combustion and heating to achieve the purpose of preparing hot water. Generally, the working principle of a gas water heater is that the hot water valve is opened, and cold water enters the water heater from the water inlet pipe; among them, after the cold water enters the water heater, it flows through the water-gas valve body, and under the action of the pressure difference of the water flow, the water-gas valve is pushed, and At the same time, push the micro switch of the DC power supply to turn on the power and start the pulse igniter. At the same time, open the gas trans...

Problems solved by technology

In this way, not only the comfort of bathing is greatly reduced, but also it is easy for the user to catch a cold due to the "surprise" of cold water, which will lead to illness.
