Abstract
The invention discloses an anti-downdraft device for an outdoor gas water heater. The anti-downdraft device comprises an outer shell and a continuing opening. The continuing opening is positioned inside the outer shell, and the lower portion of the continuing opening stretches out of the outer shell to be connected with a water heater smoke exhaust opening. The device further comprises a wind disk and a top cover, the wind disk is sunken downwards, and an upper end opening is sealed by the lower end of the wind disk; the wind disk is positioned in the continuing opening, and the upper end of the wind disk stretches out of the continuing opening upwards; and the top cover covers the upper end opening of the wind disk, and a gap is reserved between the top cover and the upper end opening face of the wind disk. Strong wind is blocked by the top cover, and flow dividing is carried out on the strong wind through the downwards-sunken wind disk, so that the strong wind is prevented from entering the gas water heater from the continuing opening; the influence of the downdraft of the strong wind on combustion of the water heater can be effectively avoided; and the top cover covers the continuing opening, so that rainwater is prevented from entering the continuing opening, and the rainwater is prevented from entering the water heater.
Description
Technical field
The present invention relates to a kind of down draught device, be specifically related to a kind of outdoor gas water heater backward-wind preventing device.
Background technology
Outdoor gas water heater in the market has high wind or runs into rainy weather during in the external world, high wind and rainwater can enter water heater inside by enclosure, corrosion is caused to water heater inside, also can affect the normal ignition burning of water heater, occur the exception stopped working in jump fire and midway.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of outdoor gas water heater backward-wind preventing device, high wind and rainwater can be avoided to enter water heater inside, ensure the normal use of water heater.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of outdoor gas water heater backward-wind preventing device, comprise shell and port, described port is positioned described enclosure, the bottom of described port is stretched out described shell and is connected with water heater exhaust opening, also comprise wind disk and top cover, described wind disk is to lower recess, described wind disk lower end closed upper end open, described wind disk is positioned the inside of described port, the upper end of described wind disk protrudes upward described port, described top cover covers the upper end open of described wind disk and and leaves gap between the upper end open face of described wind disk.
As a further improvement on the present invention, the structure that described wind disk is positioned the inside of described port is: three first supports are fixed at the inwall interval of described port, and described wind disk is fixed on described three first supports.
As a further improvement on the present invention, described top cover cover described wind disk upper end open and and the structure leaving gap between the upper end of described wind disk be: four L-type second supports are fixed at described shell upper end-face edge interval, one end of described second support level section is fixedly connected with described shell upper end-face edge, the other end extends towards the center of described shell, one end of the vertical section of described second support is connected with the other end of described second support level section, the other end of the vertical section of described second support upwards extends, described top cover is fixed on the other end top of the vertical section of described second support, the diameter of described top cover is less than the diameter of described shell.
As a further improvement on the present invention, the outer wall of described port fixes a water conservancy diversion water pond, and described water conservancy diversion water pond is positioned at the below of described shell, and the sidewall of described water conservancy diversion water pond is provided with breach.
As a further improvement on the present invention, described wind disk is horn-like.
The invention has the beneficial effects as follows: by top cover blocks high wind, by the wind disk shunting high wind to lower recess, thus prevent high wind from entering in gas heater by port, effectively can solve high wind downdraught to burn the impact caused on water heater, cover above port by top cover, thus stop that rainwater enters port, avoid rainwater to enter water heater inside.

Detailed description of the invention
Embodiment: a kind of outdoor gas water heater backward-wind preventing device, comprise shell 1 and port 2, it is inner that described port 2 is positioned described shell 1, the bottom of described port 2 is stretched out described shell 1 and is connected with water heater exhaust opening, also comprise wind disk 4 and top cover 5, described wind disk 4 is to lower recess, described wind disk 4 lower end closed upper end open, described wind disk 4 is positioned the inside of described port 2, the upper end of described wind disk 4 protrudes upward described port 2, described top cover 5 covers the upper end open of described wind disk 4 and and leaves gap between the upper end open face of described wind disk 4.When external wind presses through large, high wind carries out stopping and shunting through top cover 5 and wind disk 4, enter in gas heater to guarantee directly to pour in down a chimney, the problem such as avoid occurring jump fire and midway is flame-out, when raining in the external world, stop rainwater by top cover 5, prevent rainwater from entering port 2, thus avoid in rainwater gas heater.
The structure that described wind disk 4 is positioned the inside of described port 2 is: three first supports 6 are fixed at the inwall interval of described port 2, and described wind disk 4 is fixed on described three first supports 6.
Described top cover 5 cover described wind disk 4 upper end open and and the structure leaving gap between the upper end of described wind disk 4 be: four L-type second supports 7 are fixed at described shell 1 upper end-face edge interval, one end of described second support 7 horizontal segment is fixedly connected with described shell 1 upper end-face edge, the other end extends towards the center of described shell 1, one end of the vertical section of described second support 7 is connected with the other end of described second support 7 horizontal segment, the other end of the vertical section of described second support 7 upwards extends, described top cover 5 is fixed on the other end top of the vertical section of described second support 7, the diameter of described top cover 5 is less than the diameter of described shell 1.Make top cover 5 higher than wind disk 4 by L-type second support 7, the gas that exhaust opening is discharged is discharged smoothly, and the diameter that the diameter of top cover 5 is less than described shell 1 makes exhaust efficiency more.
