Safety ignitor for gas water heater

Abstract

The invention relates to a safe ignition device for a gas-fired water heater, comprising fuel gas pipe, igniter, fuel gas valve and combustion chamber, and characterized in that it adds a bypass gas supply pipe and bypass valve on the fuel gas pipe, where as igniting, the bypass valve is turned on, and the used fuel gas is supplied by the bypass gas supply pipe, and after the ignition succeeds, the bypass valve is turned off, the fuel gas used for the gas-fired water heater is supplied by the original fuel gas pipe. And it assures the ignition is smooth and makes the use of the gas-fired water heater safer and more convenient.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a safety ignition device for the gas water heater. Background technique [0002] Gas water heaters are necessary for many families. When using gas water heaters in different seasons, the water temperature must be adjusted to an appropriate level. At the same time, different family members have different feelings and habits of water temperature. It is also necessary to adjust the water temperature to the temperature that you think is appropriate. The adjustment of the water temperature is mainly realized by adjusting the size of the flame, that is, adjusting the gas supply volume. If you use a gas water heater in the hot summer, the temperature of the tap water itself is no longer If the temperature is too low, the heating program is very small, so only a small air supply is required, but generally when the water heater is ignited, there must be enough air supply, otherwise the ignition canno...

[0002] Gas water heaters are necessary for many families. When using gas water heaters in different seasons, the water temperature must be adjusted to an appropriate level. At the same time, different family members have different feelings and habits of water temperature. It is also necessary to adjust the water temperature to the temperature that you think is appropriate. The adjustment of the water temperature is mainly realized by adjusting the size of the flame, that is, adjusting the gas supply volume. If you use a gas water heater in the hot summer, the temperature of the tap water itself is no longer If the temperature is too low, the heating program is very small, so only a small air supply is required, but generally when the water heater is ignited, there must be enough air supply, otherwise the ignition cannot be successful, so the user can only first Open enough air intake, after the ignition is successful, turn off the air intake to reduce the flame

But there is a problem here. For the sake of safety, many families install the water heater in the ventilated place outside the bathroom. Adjust the air intake, which will bring a lot of inconvenience to the user

In addition, there is another problem. Even if the water heater is installed in the bathroom, the user first increases the intake air volume and then lowers the intake air volume after the ignition is successful. At this time, the flame becomes smaller and the water temperature is suitable. The water heater comes out. If you want to turn on the water heater in the future, you may not be able to ignite sequentially because the air supply is too small. The user has to readjust the air intake. If the user uses body lotion on his face and cannot open his eyes at this time, adjust according to his feeling. Air volume is dangerous, burns may occur due to excessive air volume
