Method for controlling supercharged gas water heater and gas water heater

Abstract

The invention discloses a method for controlling a supercharged gas water heater and the gas water heater. The gas water heater comprises a turbocharging device, a liquid driving device and a gas pressure detecting device. The turbocharging device is arranged on a gas inlet pipeline, and the liquid driving device drives liquid to flow through the turbocharging device and drives the turbocharging device to run. According to the gas water heater, the liquid driving device is controlled to drive / close the turbocharging device according to a gas pressure value detected by the gas pressure detecting device, and gas is supercharged / stopped from being supercharged. According to the gas water heater, the gas can be supercharged when the gas pressure is low, the gas inlet pressure and stability areguaranteed, and therefore it is guaranteed that the optimum combustion work condition is matched; and the temperature and stability of water output are guaranteed, energy consumption can be reduced,and the bath experience of a user is improved.

Description

technical field [0001] The invention belongs to the field of water heaters, and in particular relates to a control method of a pressurized gas water heater and a gas water heater. Background technique [0002] Gas water heaters are fast water heaters that burn fuel to transfer heat to water, and are becoming more and more popular with ordinary home users. However, the combustion effect of the gas water heater will be limited by the gas supply conditions of the user's home. In some users' homes, due to insufficient gas supply pressure in the overall pipe network or insufficient gas supply during peak gas consumption, the gas water heater may not work normally, affecting the hot water output. 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 tha...

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
