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 drop during the peak gas consumption If it i

Example Embodiment

[0035] Embodiment one

[0036] like figure 1 As shown, this embodiment provides a control method for a pressurized gas water heater. The gas water heater includes a gas booster device 4 and a gas pressure detection device 5. The gas water heater is turned on / off according to the pressure value of the gas detected by the gas pressure detection device 5. Gas supercharging device 4 is used to perform / stop supercharging gas.

[0037] In this embodiment, the gas water heater with supercharging function includes a heat exchange device, a combustion chamber 2, and a gas intake pipeline 3. The heat source, the water in the heat exchange device flows out from the water outlet after heat exchange, and is used for bathing by users.

[0038] The gas intake pipeline 3 is provided with a gas booster device 4, which can pressurize the gas. The gas pressurizing device 4 may include various types, and it only needs to be able to pressurize the gas in the gas intake pipeline 3 . For example...

Abstract

The invention discloses a control method of a supercharged gas water heater and the gas water heater. The gas water heater comprises a gas supercharging device and a gas pressure detection device. Thegas water heater opens/closes the gas supercharging device according to pressure value, detected by the gas pressure detection device, of gas, and the gas is supercharged or stopped supercharging. The gas water heater comprises a control device, when the gas pressure detection device detects that the real-time gas pressure value N is lower than the preset value N1, a signal is transmitted to thecontrol device, the control device controls the gas supercharging device to act, and the gas is supercharged. According to the control method, when it is detected that the gas pressure is low, the gasis supercharged, the gas inlet pressure and stability are ensured, it is ensured that an optimal combustion working condition is matched, the water outlet temperature and stability are ensured, and the user bathing experience can be greatly 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] 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...
