Embodiment Construction

[0021] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0022] figure 1 A functional block diagram of a gas water heater gas leakage detection device according to a preferred embodiment of the present invention is schematically shown.

[0023] Specifically, as figure 1 As shown, the gas water heater gas leakage detection device according to the preferred embodiment of the present invention includes: a control unit 10 and a reminder unit 20 .

[0024] Wherein, the control unit 10 is configured to start the reminder unit 20 by sending a reminder activation signal to the reminder unit 20 so that the reminder unit 20 sends a reminder message.

[0025] For example, the reminder unit 20 includes a flashing light and / or a buzzer.

[0026] And, if figure 1 As shown, the gas water heater gas leakage detec...

Abstract

The invention provides a gas leakage detection device for a gas water heater. When a water heater water outlet temperature measuring unit continuously senses that the water temperature at a hot water outlet is lower than a preset temperature in a lasting preset time period, the water heater water outlet temperature measuring unit sends a gas flow detection signal to a control unit; the control unit starts a gas outlet gas flow measuring unit when receiving the gas flow detection signal from the water heater water outlet temperature measuring unit so as to sense the airflow velocity of water at a gas connector; besides, when the gas outlet gas flow measuring unit detects that the airflow velocity of the water at the gas connector is larger than a preset flow velocity, the gas outlet gas flow measuring unit sends a gas warning signal to the control unit; the control unit sends a reminding starting signal to a reminding unit when receiving the gas warning signal from the gas outlet gas flow measuring unit so as to start the reminding unit and make the reminding unit send out a reminding message.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, the invention relates to a gas water heater gas leakage detection device. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. [0003] 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 ignition is successful and enter...
