Smoke exhaust structure for anti-freezing gas engine

Abstract

The invention discloses a smoke exhaust structure for an anti-freezing gas engine and relates to the field of gas water heaters. The smoke exhaust structure comprises a smoke exhaust pipe and a fan which are mutually connected. A fixed plate with the size the same as the pipe diameter of the smoke exhaust pipe is arranged in the smoke exhaust pipe. The central axis of the fixed plate coincides with the central axis of the smoke exhaust pipe. A fixed magnetic plate is embedded into the center position of the fixed plate. Multiple fixed smoke outlet holes are annularly formed in the position, close to the edge position, of the fixed plate. A non-elastic connecting bag connected to the inner wall of the smoke exhaust pipe in a sealed manner is arranged on the outer side of the fixed plate. A movable magnetic plate which is parallel to the fixed plate and coaxial with the fixed plate is arranged on the non-elastic connecting bag. A movable smoke outlet hole is formed in the center position of the movable magnetic plate. According to the working principle, by arranging a gas reverse flow prevention structure, the situation that cold air enters the gas engine through the smoke exhaust pipe and freezes and damages a water pipe is prevented, the gas engine structure is not changed, only a smoke exhaust structure is replaced, the improvement cost is low, the energy utilization rate of the gas engine is high, and the problem that the energy utilization rate of an existing anti-freezing gas engine is low is solved.

Description

technical field [0001] The invention relates to the field of gas water heaters, in particular to a smoke exhaust structure for an antifreeze gas engine. Background technique [0002] Since the heat exchange medium of the gas engine is water, it cannot be installed outdoors in the north. However, due to factors such as the difficulty in installing the exhaust pipe when installed indoors, most users do not install the exhaust pipe in actual use. Therefore, in winter, because the smoke cannot be exhausted, accidents of "poisoning" of personnel occur from time to time. It is also very common to install the smoke exhaust pipe, and because the cold wind enters the gas engine through the smoke exhaust pipe in winter, the phenomenon of freezing and cracking the water pipe is also very common. Therefore, the installation and use of gas engines in the north has indeed brought a lot of inconvenience to users, which has affected the development of gas engines in the north. [0003] T...
