Exhaust hood assembly for outdoor gas water heater

Abstract

The invention discloses an exhaust hood assembly for an outdoor gas water heater. The exhaust hood assembly comprises a flow guide shell, an inner container and an outlet member, wherein the outlet member is fixed on a wall; the inner side of the top of the flow guide shell and the inner side face of the flow guide shell opposite to the open side form a smoke flow passage from bottom to an open side face of the shell with the upper surface of the inner container and the outer side face of the inner container opposite to the open side face of the shell respectively; the upper surface of the inner container has an inclined plane flow guide structure which ascends inwards from the position of the outlet member, so that a section of ascending smoke flow passage is formed; the inner container structure can greatly improve a wind resistance coefficient of strong wind which enters a machine, so that the machine is not influenced by the strong wind during normal combustion; and through the device, high-temperature smoke which flows through the device can be effectively guided to the exterior of the machine.

Description

technical field [0001] The invention relates to an exhaust hood, in particular to an exhaust hood combination for an outdoor gas water heater. Background technique [0002] The classification of gas water heaters can be roughly divided into two types: indoor type and outdoor type according to the installation method. Traditional outdoor gas water heaters are poorly designed, and some of them just add a rain cover to the indoor type water heaters. Corrosion enters the inside of the machine, causing damage to the internal components of the machine and making the machine unable to work normally. And when the machine is burning normally, the burning state of the flame is disturbed by the strong wind from the outside entering the machine, causing the flame to turn yellow, fly away and leave the fire. As a result, the heat exchanger, an important part of the gas water heater, is damaged, which reduces the service life of the water heater. Contents of the invention [0003] In ...

AI Technical Summary

Problems solved by technology

[0002] The classification of gas water heaters can be roughly divided into two types: indoor type and outdoor type according to the installation method. Traditional outdoor gas water heaters are not well designed due to structural design. Corrosion enters the inside of the machine, causing damage to the internal components of the machine and making the machine damaged and unable to work normally

And when the machine is burning normally, the burning state of the flame is disturbed by the strong wind from the outside entering into the machine, causing the flame to turn yellow, fly away and leave the fire.

Even damage the heat exchanger, an important part of the gas water heater, and reduce the service life of the water heater
