Household gas water heater capable of automatically alarming

Abstract

The invention relates to a household gas water heater capable of automatically alarming. The household gas water heater comprises a main body device, a gas detector, a carbon monoxide concentration detection device, an infrared human detection sensor and a controller of the household gas water heater, wherein the controller is respectively connected with the gas detector, the carbon monoxide concentration detection device and the infrared human detection sensor; whether gas alarm is performed according to the detection results of the gas detector, the carbon monoxide concentration detection device and the infrared human detection sensor; and the controller, the gas detector, the carbon monoxide concentration detection device and the infrared human detection sensor are attached to the main body device. According to the household gas water heater, insufficient gas combustion and gas concentration in indoor air can be detected, and the gas alarm information is timely transmitted to residents, so that the residents can take measures, the possible potential safety hazard of gas explosion and carbon monoxide poisoning is avoided, and the personal and property safety is guaranteed.

Description

technical field [0001] The present invention relates to a domestic gas water heater with automatic alarm, in particular to a domestic gas water heater with automatic alarm installed indoors and can determine whether to alarm according to the gas leakage situation. , It can automatically analyze the incomplete combustion of gas and the concentration of indoor gas, and actively find solutions to ensure the safety of house property and personal safety. Background technique [0002] The basic working principle of the gas water heater is that cold water enters the water heater, flows through the water-gas linkage valve body, under the action of a certain pressure difference of the flowing water, pushes the water-gas linkage valve, and at the same time pushes the DC power micro switch to turn on the power and start the pulse The igniter, at the same time, open the gas transmission electromagnetic valve, and continue to ignite automatically through the pulse igniter until the ignit...

Problems solved by technology

[0003] However, the combustion chamber of the existing gas water heater is usually not sealed, and the water heater is installed indoors. The oxygen required for the combustion of the water heater is also taken from the room, and the waste gas produced by the combustion is discharged to the outside through the flue, so the water heater cannot be installed in the bathroom. At the same time, due to the natural air intake during combustion, the incomplete mixing of gas and air affects the thermal efficiency. Incomplete combustion will also produce carbon monoxide, which will cause poisoning of indoor residents, or gas leakage will mix with oxygen, which will easily cause an explosion, which will cause personal and property damage.
