Problems solved by technology

However, the combustion effect of gas water heaters will be limited by the gas supply conditions of users' homes. Some users' homes may have problems with gas water heaters not working properly due to insufficient gas supply pressure of the overall pipe network or insufficient gas supply during peak gas consumption, affecting hot water production. The speed and user bathing experience
[0003] At present, the maximum gas pressure in my country is about 3000Pa, but the gas pressure is seriously insufficient during the peak gas consumption, which will inevitably cause the following problems: First, the gas pressure may be lower than 1000Pa during the peak gas consumption, resulting in the failure of the gas water heater to start normally; The working principle of gas water heaters, low air pressure directly affects the speed of hot water outlet; third, the poor stability of air pressure affects the stability of outlet water temperature, which will be directly felt by users during use, greatly affecting user experience
[0004] At present, there are no related gas booster water heater products in the market. When the pressure is low, the ratio of gas to air is only adjusted by controlling the proportional valve, and the pressure stability of the gas behind the proportional valve is improved by increasing the opening of the proportional valve. The effect of this method is very limited when the pressure is below 1000Pa

Abstract

The invention discloses a supercharged gas water heater. The supercharged gas water heater comprises a combustion cavity and a gas inlet pipeline, wherein the gas inlet pipeline is connected with thecombustion cavity; gas enters the combustion cavity to combust; a waste gas exhaust pipeline is arranged on the combustion cavity; a turbine device is arranged in the waste gas exhaust pipeline; a supercharging device is arranged on the gas inlet pipeline; the turbine device is connected to the supercharging device; and while the turbine device rotates, the supercharging device is driven to perform supercharging on gas. The gas water heater disclosed by the invention can recycle kinetic energy and heat energy of waste gas to supercharge gas, so that gas inlet pressure and stability can be guaranteed, the optimal combustion working condition can be guaranteed to be matched, outlet water temperature and stability are guaranteed, energy consumption and cost further can be reduced, and user bathing experience is greatly improved.

Description

technical field [0001] The invention belongs to the field of water heaters, and in particular relates to a pressurized gas water heater. Background technique [0002] A gas water heater is an instant water heater that burns fuel to transfer heat to water, and is becoming more and more popular among ordinary household users. However, the combustion effect of gas water heaters will be limited by the gas supply conditions of users' homes. Some users' homes may have problems with gas water heaters not working properly due to insufficient gas supply pressure of the overall pipe network or insufficient gas supply during peak gas consumption, affecting hot water production. Speed ​​and user bathing experience. [0003] At present, the maximum gas pressure in my country is about 3000Pa, but the gas pressure is seriously insufficient during the peak gas consumption, which will inevitably cause the following problems: First, the gas pressure may be lower than 1000Pa during the peak g...
