Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wall-mounted ventilator used for indoor ventilation in a ship's cabin or a land building.

[Conventional technology]

For example, as shown in the side view of FIG. 3, conventionally, as a ventilation tube attached to a ship's cabin wall, a tube 01 is formed by cutting a tube at right angles to the axis and is attached horizontally to an outer wall 011, and a watertight lid is attached to the tip of the tube. 08 with a horizontal pin, or as shown in the side view of Figure 4, an elbow-shaped cylinder 01' with the tip bent downward at an angle of less than 90 degrees is installed horizontally on the outer wall 011, and an elbow-shaped cylinder is used. An elbow type is known in which a watertight lid 08' is similarly supported by a horizontal pin at the tip of the lid 01'.

Here, 012 is the cabin.

However, such a structure has the following drawbacks.

(1) If the horizontal type is exposed to wind and rain with the watertight lid 08 open, the rainwater collected in the tube 01 will easily flow into the ship due to the ship's rolling, etc.
The cabin 012 will be soiled.

(2) Elbow type cylinder 01'
Since it takes a lot of man-hours to manufacture, the cost of the product increases.

[Problem that the invention attempts to solve]

The present invention was proposed in view of the above circumstances, and aims to provide an economical wall-mounted ventilation tube in which rainwater does not flow in and the tube body is easy to manufacture.

[Means for solving problems]

To this end, the present invention has developed a wall-mounted ventilation tube in which a cylindrical member produced by cutting a pipe is fixed to the outer surface of a steel wall. The present invention is characterized in that a cylindrical member having beveled cut ends forming an intersecting angle of 30 to 60° is fixed to a steel wall with the right-angled cut surface facing downward.

[Effect]

With the above-mentioned configuration, it is possible to obtain an economical walled ventilation tube in which rainwater does not flow in and the tube body is easy to manufacture.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings.
FIG. 1 is a side view thereof, and FIG. 2 is a plan view showing how the oblique cut tube shown in FIG. 1 is cut from a long tube.

In the above figure, the same symbols as in Figs. 3 and 4 indicate the same members as in the same figure, and 1 has a circular or square cross-sectional shape and is cut at an angle at one end 3 and at a right angle at the other end 4 with respect to the axis 2. 5 is a long tube from which a plurality of diagonally cut tubes 1 are cut out, 6 is a cutting line when one end 3 of the diagonally cut tube 1 is cut from the long tube 5, and 7 is a diagonally cut tube. With the other end 4 of the tube 1 facing downward, one end 3
When installed on the outer wall 011, a diagonally downward ventilation tube, α, with a watertight lid 8 pivoted on the other end 4 by a horizontal pin 9 is installed.
is the intersection angle between the longitudinal direction of the long tube 5 and the cutting line 6, and the intersection angle α is 30 to 60°.

In such a structure, the oblique downward ventilation pipe 7
Since the opening of the cabin 012 is oriented diagonally downward, rainwater will not flow into the cabin 012 in the event of wind and rain.

Further, since the main body of the diagonally downward ventilation tube 7 can be easily obtained by cutting the long tube 5, the number of processing steps is reduced, and furthermore, the mounting surface of the outer wall 011 of the diagonal downward ventilation tube 7 is a flat surface. Therefore, the number of installation steps is also reduced.

According to such a structure, the following effects can be achieved.

(1) Since rainwater does not flow into the cabin through the ventilator opening, the cabin will not be contaminated.

(2) Man-hours for processing and installing ventilation pipes are reduced.
Its economic efficiency is improved.

[Effect of idea]

In short, according to the present invention, in a wall-mounted ventilation tube made by cutting a tube and fixing it to the outer surface of a steel wall, a right-angled cut end that makes an angle of 90° to the axis, On the other hand, by fixing a cylindrical member having beveled cut ends that form an intersecting angle of 30 to 60 degrees with the right-angled cut surface facing downward and fixing the beveled cut ends to a steel wall, rainwater does not flow into the tube body. The present invention is extremely useful industrially because it provides an economical walled ventilator that is easy to manufacture.
