Description

Technical Field

[0001] This utility model relates to a gas water heater, and more particularly to a permanent flame device for a gas water heater. Background Technology

[0002] The existing technology, Chinese patent 202420384573.8, describes a flue-type gas water heater with a permanent flame. It includes a main body comprising a water tank, a burner, a water-gas linkage valve, a piezoelectric switch, and a permanent flame assembly. The burner includes an ignition plate. A permanent flame gas passage acting on the ignition plate is provided between the permanent flame assembly and the water-gas linkage valve. A main gas passage entering the burner is provided between the water-gas linkage valve and the burner. A liquid inlet passage is provided between the water-gas linkage valve and the water tank. The permanent flame gas passage is opened by the water-gas linkage valve, and the piezoelectric switch causes the permanent flame assembly to generate an open flame acting on the ignition plate. The water-gas linkage valve includes a gas valve core acting on the main gas passage. Liquid enters the water tank through the liquid inlet passage and pushes the gas valve core to open the main gas passage, allowing gas to enter the burner. This gas water heater does not require a power connection, making it convenient and quick. However, the problem is that the permanent flame power is low, and the electrical charge generated by the sensing needle due to the temperature difference is insufficient, causing the solenoid valve to close, affecting its use.
