The gas-fired positive displacement water heater emits a certain amount of exhaust gas when in operation. Exhaust gas is generally discharged outdoors by exhausting flue gas through an exhaust pipe under the action of natural draft or a fan; the exhaust pipe is connected to the outside of the room, and the exhaust is performed by using natural draft or a fan. The existing gas positive-displacement water heater can be in a state of unexpected blockage or backflow of an external flue in the exhaust process, but the gas positive-displacement water heater still works continuously, the generated waste gas can not be effectively discharged out of the room, the temperature of the external flue is increased, the parts are damaged under continuous high temperature, and a large amount of smoke is retained in the room, so that a certain potential safety hazard can be brought to a user.
This application is for solving the problem of the unexpected jam of external flue or backflow wind when the above-mentioned positive-displacement gas heater appears in the exhaust process, and the potential safety hazard that brings provides a positive-displacement gas heater of taking temperature detection, see the fig. 1 and show, fig. 1 is the schematic diagram of the positive-displacement gas heater that this application an exemplary embodiment shows, includes: an external flue 100, wherein one end of the external flue 100 is led to the outside of the room, and the other end is connected with a smoke hood assembly 200; one end of the smoke hood assembly 200, which is far away from the external flue 100, is connected with the upper cover 500 of the water heater; the external flue 100, the hood assembly 200 and the inner cavity of the water heater upper cover 500 are communicated with each other to form the smoke discharging channel 400.
The water heater upper cover 500 completely covers the water heater, the water heater upper cover 500 is provided with a smoke exhaust opening, and the smoke hood assembly 200 completely surrounds the opening of the water heater upper cover 500, so that smoke generated in the working process of the gas positive-displacement water heater can directly enter the smoke hood assembly 200.
The smoke baffle 300 is arranged in the inner cavity of the smoke hood assembly 200, the smoke baffle 300 is arranged in the smoke exhaust channel 400 at the joint of the smoke hood assembly 200 and the external flue 100, and a certain interval is arranged between the smoke baffle 300 and the inner wall of the smoke exhaust channel 400.
In the case of the smoke baffle 300, the smoke is discharged from the space between the smoke baffle 300 and the inner wall of the smoke discharge channel 400, and in the case of natural smoke discharge, the smoke baffle 300 only splits the discharged smoke and does not cause smoke backflow; during the backward flow of smoke, the backward flow and the outward discharge of smoke are collected at the inner edge of the hood assembly 200 by the influence of the smoke barrier 300.
