Abstract

The invention discloses a safety protection device of a smoke discharge pipe of a gas water heater. The safety protection device comprises a first electric conductor arranged on the smoke discharge pipe and extending along the axial direction of the smoke discharge pipe from the first end of the smoke discharge pipe to the second end of the smoke discharge pipe. The first end is the interface end for the smoke discharge pipe and the gas water heater. The second end is the tail end of the smoke discharge pipe extending the outside. The first electric conductor is connected with a control circuit of the gas water heater to form a loop. The first electric conductor can break when the smoke discharge pipe breaks or is moved and misplaced. The electric conductor is arranged in the axial direction of the smoke discharge pipe, so that the electric conductor and the control circuit in the e gas water heater form the loop. When the smoke discharge pipe is displaced, misplaced or disconnected, the electric conductor can break to cause disconnection of the loop, accordingly the water heater stops operating, and the safety protection effect is played.

Description

Technical field [0001] The invention relates to the safety protection technology for gas appliances, in particular to a safety protection device for the exhaust pipe of a gas water heater. Background technique [0002] The safe use of indoor domestic gas water heaters has always been a major issue in the industry. Numerous accidents of casualties caused by the use of domestic gas water heaters are caused by the failure to install the smoke exhaust pipe or the irregular installation of the smoke exhaust pipe. [0003] Gas water heaters need to consume a lot of air (or oxygen O 2 ), most of the products in the flue gas after combustion are CO 2 And a very small amount of CO. In winter, the operating room is often in a relatively closed environment. Once the gas water heater is running, the burned flue gas cannot be discharged outdoors, the flue gas will enter the water heater and mix with the gas for combustion. Due to the continuous consumption of oxygen, the combustion will gradual...
