Problems solved by technology

[0003] 1. When the wind pressure is too high, the flue gas cannot be discharged normally, which will affect the combustion of gas and reduce the efficiency
[0004] 2. The wind blows back into the water heater, which will lead to backfire, flameout, CO exceeding the standard and other dangerous situations
[0005] 3. In winter, when the water heater is not working, the cold air will cause the water heater to freeze and crack

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 , figure 2 and image 3 As shown, the gas water heater anti-downdraft smoke pipe in this embodiment includes a first smoke pipe 1 , a second smoke pipe 2 socketed with the first smoke pipe 1 , and a flow guide block 6 .

[0023] The second smoke pipe 2 includes a straight section 21 and a flaring section 22 connected to the straight section 21. The gas outlet end of the straight section 21 forms a smoke exhaust passage, and the gas outlet end of the first smoke pipe 1 extends into the flaring section 22. An annular exhaust passage 3 is formed between the outer wall of the smoke pipe 1 and the inner wall of the flaring section 22 .

[0024] The deflector block 6 is elastically arranged on the air outlet end of the first smoke pipe 1 through a spring. When the wind is strong, the flow guide block 6 can compress the sm...

Abstract

An anti-air-backflow smoke tube of a gas water heater is characterized by comprising a first smoke tube (1) and a second smoke tube (2), wherein the second smoke tube (2) comprises a straight section(21) and a flaring section (22) connected to the straight section (21); an annular exhaust channel (3) is formed between the outer wall of the first smoke tube (1) and the inner wall of flaring section (22); a diversion block (6) which can compress a smoke discharge hole in an air outlet end of the first smoke tube (1) when wind strength is high is disposed elastically at the air outlet end of thefirst smoke tube (1); and air which enters from the second smoke tube (2) can be led by the diversion block (6) into the exhaust channel (3). When a wind pressure is high, the anti-air-backflow smoketube of the gas water heater can effectively enhance a combustion state of fuel gas; fuel gas consumption can be reduced; and resources can be saved. In addition, occurrence of dangerous situations such as tempering and CO exceeding can be reduced.

Description

technical field [0001] The invention relates to a smoke exhaust pipe, in particular to a smoke exhaust pipe applied to a gas water heater. Background technique [0002] When the gas water heater is installed in a high-rise building or in a windy place, due to the excessive outdoor wind pressure, it will affect the normal combustion of the gas and seriously affect the user's use and safety. Specifically, the following problems will occur: [0003] 1. When the wind pressure is too high, the flue gas cannot be discharged normally, which affects the combustion of gas and reduces the efficiency. [0004] 2. If the wind blows backwards into the water heater, it will lead to dangerous situations such as flashback, flameout, and CO exceeding the standard. [0005] 3. In winter, when the water heater is not working, the cold air will cause the water heater to freeze and crack. [0006] In terms of anti-backwind, many efforts and attempts have been made in the prior art, as shown in...
