Power supply device of gas water heater

Abstract

The invention provides a power supply device of a gas water heater. The power supply device of the gas water heater comprises a power supply module, a wire, a shell and a flow switch, wherein the power supply module is arranged in the shell; a commercial power input contact is connected to 220V commercial power; a DC output end of the power supply module is connected with a battery box output end of the gas water heater; the flow switch is connected to a water inlet pipe of the gas water heater; and an AC input end of the power supply module is electrically connected with the commercial power input contact, another AC input end of the power supply module is electrically connected with one end of a contact of the flow switch, and the other end of the contact of the flow switch is electrically connected with another commercial power input contact. When the gas water heater is used, the contact of the flow switch is automatically closed, the AC input ends of the power supply module and the 220V commercial power are connected, a DC output end provides the gas water heater with electricity for ignition, so that the water heater is normally used. Flow of the gas water heater is closed, the contact of the flow switch is automatically cut off, the AC input ends of the power supply module and the 220V commercial power are cut off and the DC output end stops providing the water heater with the electricity after use. The power supply device is simple in structure, convenient and reliable to use and easy to manufacture.

Description

technical field [0001] The invention relates to a power supply device for a gas water heater, in particular to a device for supplying power to a straight row or flue gas water heater with commercial power. Background technique [0002] Gas water heaters are widely used in people's lives. At present, both direct discharge and flue gas water heaters are ignited by dry batteries. The main problems are: 1. Frequent replacement of batteries, large battery consumption and high cost; Disposal of old batteries at will is not conducive to environmental protection; 3. During use, the water heater often turns off due to insufficient battery power, especially when this happens in the middle of a bath in severe winter, and the degree of discomfort can be imagined. Contents of the invention [0003] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a device that utilizes commercial power to supply power for direct exhaust ...
