Smoke discharge pipe assembly for gas-fired equipment

Abstract

The invention provides a smoke discharge pipe assembly for gas-fired equipment. The smoke discharge pipe assembly at least comprises a first smoke discharge pipe and a second smoke discharge pipe, wherein a conductor is respectively arranged on the first smoke discharge pipe and the second smoke discharge pipe, the smoke discharge pipe assembly also comprises a pipe connecting mechanism, the pipe connecting mechanism is connected between the first smoke discharge pipe and the second smoke discharge pipe for realizing the fixed mechanical connection of the first and second smoke discharge pipes, and meanwhile, the elastic connection of conducting bodies of the first and second smoke discharge pipes is realized. Through the introduction of the pipe connection mechanism, the mechanical connection between the adjacent smoke discharge pipes becomes stable, firm and reliable, so that the displacement, staggering or disconnection condition is reduced. Even when the conditions occur, or the breaking of a circuit formed by connecting the conducting bodies of the smoke discharge pipes in series is caused when the installation is not carried out according to the specification, a control circuit of a gas water heater can detect the condition, and corresponding measures such as hot water operation stopping can be executed, so that the waste gas leakage can be further prevented.

Description

technical field [0001] The invention belongs to the field of household gas equipment, and in particular relates to a smoke exhaust pipeline for gas equipment. Background technique [0002] Household gas equipment includes gas water heaters, gas boilers, gas stoves, etc. These gas-fired devices usually require a fume hood and a smoke exhaust pipe to collect and exhaust the waste gas (including carbon monoxide and nitrogen oxides) generated by combustion during the operation of the device to the outside. The smoke exhaust pipeline is usually composed of multiple smoke exhaust pipes in series. These smoke exhaust pipes are manufactured by the manufacturer in accordance with the corresponding safety standards and need to be correctly assembled at the user's home in accordance with the corresponding specifications. However, due to cost considerations, users or distributors may use non-standard smoke pipes, or hire workers without professional training to assemble them, which may...

Problems solved by technology

[0004] However, the above design will cause many problems in practical application

For example, the connection of the smoke exhaust pipes first needs to ensure a stable connection between the various sections of the smoke exhaust pipes. Does not provide a reliable connection between exhaust pipes
