Gas separating rod, gas water heater and gas control method

Abstract

The invention relates to a gas separating rod, a gas water heater and a gas control method. The gas separating rod comprises an inner liner tube and an outer liner tube, wherein the inner liner tube is provided with a gas inlet end and a sealing end; a gas outlet communicating the interior of the inner liner tube with the outside world is formed in peripheral surface of the inner liner tube; the outer liner tube comprises an outer liner tube body and a nozzle connected with each other; the outer liner tube body is connected with the external part of the inner liner tube in a sleeving manner; the nozzle is provided with a gas spraying hole capable of communicating the interior of the outer liner tube body with the outside world; and one of the inner liner tube and the outer liner tube bodycan be movably assembled relative to the other of the inner liner tube and the outer liner tube body to adjust the communicating area of the gas spraying hole and the gas outlet. As the outer liner tube body can move relative to the inner liner tube, and the communicating area of the gas spraying hole and the gas outlet is adjustable, the gas quantity sprayed out of the gas spraying hole of the nozzle is adjustable; as the communicating area of the gas spraying hole and the gas outlet can be selected at random, the gas quantity can be adjusted within a larger range; and as the communicating area of the gas spraying hole and the gas outlet can be selected at random, a smaller communicating area can be selected during ignition to spray a smaller quantity of gas, and the detonation phenomenonis reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas distribution rod, a gas water heater and a gas control method. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through fuel heating to achieve the purpose of preparing hot water. [0003] For consumers, the safety performance and user experience comfort of gas water heaters are extremely important reference indicators. Traditional gas water heaters use segmented solenoid valves to control the number of nozzles to open. Generally, they are divided into several segments. The number of nozzles on each segment is different. When igniting, the nozzles in one segment are controlled to ventilate, but the nozzles in each segment are ventilated synchronously, which is easy to cause Deflagration phenomenon; and the adjustment of fire...

Problems solved by technology

[0004] Based on this, it is necessary to provide a gas distribution rod, a gas water heater and a gas control method that can reduce the deflagration phenomenon and adjust the firepower in a wide range in view of the problem that the traditional gas water heater has a limited range of firepower adjustment and is prone to deflagration.
