The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.
As shown in fig. 1 and 2, a gas water heater with an expansion tank includes: a combustion chamber 3, a burner 4 arranged in the combustion chamber 3, a heat exchanger 2, and a water supply pipeline connected with the heat exchanger 2; it is characterized in that an expansion air box 1 is connected to the combustion chamber 3, and the expansion air box 1 comprises: the gas-combustion chamber is characterized by comprising a box body and an elastic film 8 arranged in the box body, wherein the inner cavity of the box body is divided into a gas chamber 9 and a pre-charging gas chamber 7 by the elastic film 8, the gas chamber 9 is communicated with the combustion chamber 3, and gas is pre-charged in the pre-charging gas chamber 7.
Wherein the elastic film 8 is a high temperature resistant rubber film such as a fluorine rubber film.
The expansion air box 1 is made of high-temperature resistant elastic materials, such as thermoplastic elastomer (TPE) or fluororubber.
The pre-inflation gas chamber 7 is provided with a gas supplement port 6 for inflation, and the gas supplement port 6 is provided with a detachable cover, such as a cover connected through threads and a cover connected through a plug-in mode.
Preferably, a connecting channel 10 for communicating the gas chamber 9 and the combustion chamber 3 is provided on the gas chamber 9.
The gas is one or more of nitrogen, air and inert gas.
Further preferably, the gas-fired water heating apparatus with an inflatable balloon further comprises a housing, and the combustion chamber 3 and the inflatable air tank 1 are both located in the housing. In other embodiments, the expansion tank may also be located outside the enclosure.
A fan 5 is connected to the combustion chamber 3.
The gas water heating equipment is a gas water heater or a gas wall-mounted furnace.
The gas chamber 9 is communicated with the combustion chamber 3 of the water heater, the pressure in the gas chamber 9 is equal to the pressure in the combustion chamber 3, when the water heater is shifted to burn or the gas pressure is unstable, the pressure in the combustion chamber 3 changes, the pressure acts on the elastic film 8 of the expansion gas box 1, the elastic film 8 generates acting force on gas pre-filled in the pre-filling gas chamber 7, the compression or stretching of the volume of the chamber is shown, so that the two sides of the film are enabled to reach a new dynamic balance, the pressure in the combustion chamber is stabilized, and the stable combustion is ensured.
For example, when the low-grade combustion is changed to the high-grade combustion, the gas is increased sharply, the pressure of the combustion chamber 3 is increased, the increased pressure acts on the elastic film 8 to compress the pre-inflation gas chamber 7, so that more gas and pressure can be contained, and new balance is achieved. When the pressure in the combustion chamber 3 is reduced, the pre-charged gas will compress the elastic membrane 8 to move towards the gas chamber 9 until reaching the equilibrium point. Therefore, the expansion chamber 1 is maintained in a balanced state by expanding it regardless of the change in the pressure in the combustion chamber. The expansion air box can only balance the pressure in the combustion chamber within a period of time of sharp change of the pressure in the combustion chamber, and the pressure balance effect on the combustion chamber 3 in the whole combustion process is not obvious.
