Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

As shown in fig. 1-4, the utility model provides an anti-back-wind smoke outlet structure of a water storage type gas water heater, the water storage type gas water heater comprises a water storage cavity 1 and a combustion chamber 2 arranged in the water storage cavity 1, the combustion chamber 2 is divided into a U-shaped structure by a partition plate, a smoke hood 3 is arranged at one end of the combustion chamber 2, the smoke hood 3 comprises an anti-back-wind air inlet channel 35 corresponding to the air inlet end of the combustion chamber 2 and a smoke outlet channel 31 corresponding to the smoke outlet end of the combustion chamber 2, and both sides of the inner part of the anti-back-wind air inlet channel 35, which are positioned at the air inlet end of the combustion chamber 2, are respectively provided with a first air guide inclined plate 32 and a second air guide inclined plate 34 to form a funnel-shaped structure.

Specifically, the first air guiding inclined plate 32 and the second air guiding inclined plate 34 form a funnel-shaped structure, which has the effect of collecting air, and the anti-down air inlet channel 35 formed by the first air guiding inclined plate 32 and the second air guiding inclined plate is understood to be a device for collecting air when blowing air, increasing forward pressure to resist the wind pressure of the smoke outlet and forming positive exhaust.

The combustion air inlet of the burner chamber or the hole is provided with 1 anti-downdraft air inlet channel 35, when wind blows in one-to-one correspondence with the air inlet of the panel 4, the air quantity entering from the air inlet is larger than that entering from the air outlet, positive pressure is formed, and good combustion working condition can be still maintained under the condition of heavy wind.

In this embodiment, as shown in fig. 3-4, the water storage type gas water heater further includes a panel 4 that is installed on one side of the smoke hood 3 and can be opened, and the positions on the panel 4 corresponding to the anti-downdraft air inlet channel 35 and the smoke outlet channel 31 are respectively installed with an air inlet grid 6 and a smoke outlet grid 5, where the air inlet grid 6 and the smoke outlet grid 5 can isolate external sundries. Meanwhile, the cigarette outlet grid 5 is of an outwards protruding boss structure, and sieve holes are densely distributed on the end face and the side wall of the cigarette outlet grid, so that the cigarette outlet grid can be rapidly diffused all around when high-temperature smoke is discharged, and the condition that the smoke is blown back by strong wind can be reduced.

In order to further improve the anti-downdraft effect, an upper anti-downdraft plate 33 is installed in the smoke hood 3 near the smoke outlet channel 31, the upper anti-downdraft plate 33 extends obliquely downwards, and the anti-downdraft plate 33 has the function of dispersing the wind blown in from the front and discharging the burnt smoke.
