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

Embodiment 1

[0037] like figure 1As shown, this embodiment provides a supercharged gas water heater, which includes a heat exchange device 7, a combustion chamber 2 and a gas intake line 3. The gas intake line 3 is connected to the combustion chamber 2, and the gas enters the combustion chamber 2 and burns to exchange for gas. The heat device 7 provides a heat source, and also includes a turbocharger device 4 and a liquid drive device 5. The turbocharger device 4 is arranged on the gas intake pipe 3, and the liquid drive device 5 drives the turbocharger device 4 to operate to pressurize the gas. .

[0038] Water such as tap water or filtered water is passed through the heat exchange device 7 of the gas water heater. The gas enters the combustion chamber 2 through the gas inlet pipe 3 for combustion, and the heat generated is transferred to the heat exchange device 7 through heat exchange, and the water in it is heated to a certain temperature and then discharged for the user to bathe.

Embodiment 2

[0062] like figure 2 As shown, this embodiment provides a control method for a supercharged gas water heater. The gas water heater in this embodiment includes a turbo supercharging device 4, a liquid driving device 5 and a gas pressure detection device 8. The turbo supercharging device 4 is arranged in the gas inlet. On the gas pipeline 3, the liquid driving device 5 drives the turbocharging device 4 to operate, and the gas water heater controls the liquid driving device 5 to drive / close the turbocharging device 4 according to the gas pressure value detected by the gas pressure detecting device 8, and perform / Stop boosting.

[0063] According to the gas pressure value detected by the gas pressure detection device 8, the gas water heater of this solution controls the liquid drive device 5 to drive / close the turbocharger device 4, and to pressurize / stop the gas, so that the pressure of the intake gas can be accurately controlled , to ensure the stability of the gas inlet pres...

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...
