Abstract

The utility model discloses a gas heater flue, a serial communication port, include: the semi-bucket type box body consists of a front baffle, a side plate, a back plate, a bottom plate and an upper net; the wall penetrating pipe is welded at the opening of the back plate of the half-bucket type box body. In actual work, after the flue is connected with the smoke outlet of the water heater, the air pressure in the flue can be effectively reduced, the downdraft is prevented from blowing out, and the device has the advantages of small volume, simple structure, low cost, long service life and convenience in disassembly and assembly.

Description

Prevent down draught and blow out gas heater flue of gas

Technical Field

The utility model relates to a gas heater, in particular to gas heater's flue.

Background

At present, a strong air exhaust device is generally installed on a household gas water heater, and the combusted smoke can be exhausted outdoors through a flue under the driving of the strong air exhaust device. However, when strong wind weather occurs outdoors, the airflow directly acts on the flue, so that the air pressure in the flue is increased and exceeds the bearing range of the strong exhaust device, the water heater generally automatically extinguishes and enters a protection state, and the water heater cannot be normally used.

Disclosure of Invention

For solving the problem of the unable normal use of above-mentioned gas heater under strong wind weather, the utility model provides a novel gas heater flue, its aim at reduces wind pressure in the flue under strong wind weather, makes it possess the ability of solving above-mentioned problem to there are characteristics such as small, with low costs, simple structure.

The utility model discloses a concrete technical scheme constitutes the box of a half bucket type by preceding baffle, two curb plates, backplate, bottom plate, opens the hole that a diameter and wall pipe diameter are the same on the backplate to weld the wall pipe on it, inside for preventing that debris from getting into the box, do not influence the discharge of burning back waste gas again, add in the box top and have the net, the bottom plate trompil, the ponding discharge in the half bucket type box of being convenient for. The wall-through pipe passes through the wall body and is connected with the flue of the gas water heater.

Because the utility model discloses a prevent down draught and blow out gas heater flue adopts the design of half confined half fill type outside the wall, makes outdoor air current can not direct action on the flue export to can change the air current direction of motion in flue exit, promote the discharge of waste gas in the flue.

Detailed Description

The utility model relates to a prevent down draught and blow out gas heater flue, concrete embodiment does, with preceding baffle, two curb plates, backplate, bottom plate with welded mode (or with stamping forming's mode) constitute the box of a half fill type, open the hole that a diameter is the same with the wall pipe diameter on the backplate to weld the wall pipe on it. The upper net is welded above the box body to prevent sundries from entering the box body. The bottom plate is provided with a hole so as to facilitate the drainage of accumulated water. During installation, the wall penetrating pipe of the flue only needs to penetrate through the wall hole to be connected with the flue of the indoor water heater, and the back plate of the box body is made to be tightly attached to the outer wall of a building, so that installation is completed.

Claims

1. The utility model provides a prevent down draught and blow out's gas heater flue which characterized in that includes: the semi-bucket type box body consists of a front baffle, a side plate, a back plate, a bottom plate and an upper net; the wall penetrating pipe is welded at the opening of the back plate of the half-bucket type box body.

2. A down draft blow out prevention gas water heater flue as claimed in claim 1 wherein the diameter of the back plate opening of the half bucket type box is the same as the diameter of the wall penetrating pipe and the upper edge of the opening is lower than the upper edge of the back plate.

3. A down draft blow out prevention gas water heater flue as recited in claim 1 wherein the floor of the half-bucket shaped box has an opening.
