Gas water heating equipment with expansion gas box

Abstract

The invention discloses gas water heating equipment with an expansion gas box. The equipment comprises a combustion chamber, a combustor, a heat exchanger and a water supply pipeline, wherein the combustor and the heat exchanger are arranged in the combustion chamber, and the water supply pipeline is connected with the heat exchanger; and the equipment is characterized in that the combustion chamber is connected with the expansion gas box, the expansion gas box comprises a box body and an elastic film arranged in the box body, the elastic film divides an inner cavity of the box body into a gaschamber and a pre-inflation gas chamber, the gas chamber communicates with the combustion chamber, and gas fills the pre-inflation gas chamber in advance. The combustion chamber of the fuel gas waterheating equipment communicates with the expansion gas box, so that the pressure in the combustion chamber is always in dynamic balance, pressure sudden change in the combustion chamber caused by gearshifting combustion or unstable air pressure is effectively avoided, flame stability is guaranteed, combustion is sufficient, meanwhile, combustion flame is stable, combustion vibration and combustion noise are not easy to generate, and therefore it is guaranteed that the whole equipment does not generate howling and noise.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas water heater with an expansion gas tank. Background technique [0002] Existing gas water heating equipment, such as gas water heaters, gas wall-hung boilers, etc., may easily lead to a sudden change in the pressure in the combustion chamber when shifting combustion or unstable air pressure, resulting in insufficient combustion of gas and poor smoke. Moreover, the sudden change in the pressure of the combustion chamber will also make the flame unstable, and the position and shape of the flame will change rapidly and irregularly, resulting in large combustion vibration and combustion noise. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a gas hot water device with an expansion gas tank with sufficient gas combustion and low noise. [0004] To achieve the above object, the pre...

AI Technical Summary

Problems solved by technology

[0002] Existing gas hot water equipment, such as gas water heaters, gas wall-hung boilers, etc., are prone to sudden changes in the pressure in the combustion chamber when shifting combustion or unstable air pressure, resulting in insufficient combustion of gas and poor flue gas.

Moreover, the sudden change in the pressure of the combustion chamber will also make the flame unstable, and the position and shape of the flame will change rapidly and irregularly, resulting in large combustion vibration and combustion noise.
