Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a rain leakage prevention device that prevents rain leakage due to snow accumulation on a roof.

(Prior Art) Conventionally, as shown in FIG. 3, snow 20 on a roof 3 in a snowy area melts due to sunlight and warm air 18 from indoors, while the temperature at the eaves 3a is the same as that of the outside air. A frozen portion 21 will be formed.

For this reason, the melted water 22 dammed up at the frozen portion 21 becomes leaking water 23 and flows into the house, causing rain leakage.

(Problems to be Solved by the Invention) The object of the present invention is to solve the above-mentioned conventional problems and provide a device for preventing rain leakage due to snow accumulation on the roof.

(Example) The device for preventing rain leakage caused by snow on a roof according to the present invention (hereinafter referred to as the device of the present invention) will be described below according to an example shown in the drawings.

1 and 2 show a device according to the invention, which has a transverse pipe 8 fixed across the roof 3 in the vicinity of the eaves 3a.

The horizontal pipe 8 is made of a synthetic resin pipe such as a vinyl chloride pipe that has poor thermal conductivity.

Next, a plurality of rows of vertical pipes 9 are provided on the roof 3, connected below the horizontal pipes 8 and separated from each other by a predetermined distance.

The lower end of the vertical pipe 9 is opened to the outside air as an exhaust port 11.

Further, the vertical pipe 9 is made of a metal pipe such as a copper pipe with good thermal conductivity.

Next, a duct 7 led from inside the attic 4 is connected to the horizontal pipe 8.

The duct 7 is for sending warm air in the attic 4, which is drawn in from the intake port 5 by the fan 6, to the horizontal pipe 8.

In the illustrated embodiment, the air inlet 5 is positioned near the top of the attic 4 where the temperature is highest.

The function of the device for preventing rain leakage caused by roof snow melting according to the present invention shown in the above embodiments is as follows.

That is, when melting the snow 20 on the roof 3, the fan 6 is driven.

As a result, warm air in the attic 4 is sucked into the duct 7 from the intake port 5 and guided to the horizontal pipe 8.

Furthermore, the warm air is sent to the vertical pipe 9, flows through the vertical pipe 9, and is discharged to the outside air from the exhaust port 11.

Here, since the vertical pipe 9 is made of a metal pipe with good thermal conductivity, the snow 20 along the vertical pipe 9 melts (the snow 20 along the horizontal pipe 8 melts).
0 does not melt very much).

As a result, streak-like melting snow portions are always formed in the snow 20 on the eaves 8a.

In other words, the frozen portion 21 on the eaves 3a is not dammed as in the conventional case, and as a result, no rain leakage occurs due to the damming action.

(Effects of the invention) The embodiments of the device for preventing rain leakage due to snow melting from a roof according to the present invention are as described above, and the effects thereof are listed below.

(1) The device of the present invention has the configuration described in the claims for utility model registration, and in particular, multiple rows of vertical pipes made of metal pipes with good thermal conductivity are provided below the horizontal pipes near the eaves. Streaks of melted snow are always formed on the snow above, and as a result, no rain leaks due to the damming action of the frozen parts.

(2) The device of the present invention has the same structure as above, and in particular, the horizontal pipe that is passed laterally on the roof is made of a synthetic resin pipe with poor thermal conductivity, so the horizontal pipe functions as a conventional snow stopper.
