DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a vent.

[0002]

2. Description of the Related Art A ventilation port provided on a pipe (duct) provided on a wall is provided with a mounting cylinder provided with a cylindrical portion to be fitted into the pipe, and a mounting pipe of the mounting cylinder. There is a configuration having a ventilation tube fitted on the front side,
There are a type in which a drain for drain is formed in the ventilation tube, and a type in which the drain is not formed.

[0003] By the way, in a ventilation opening used for exhausting and ventilating a kitchen, oil evaporating from an oil pan or the like used in the kitchen adheres to the inside of a pipe or a ventilation opening.

[0004] Therefore, in this case, a type in which a drain is not formed is adopted as the ventilation port so as to prevent oil from flowing out from the ventilation port and contaminating the wall surface and the floor surface. As you did, the mounting cylinder 21 and the ventilation cylinder
The space surrounded by the liquid reservoir 22 and the liquid reservoir 23
The method of storing the oil component is adopted.

However, this method has the following problems.

That is, the oil moves on the inner surface of the tube portion 24 and the inner surface of the mounting tube 21 to reach the liquid reservoir 23. At the time of the movement of the oil, the oil is overlapped between the mounting tube 21 and the ventilation tube 22. It leaks from the gap 25 generated in the installation part.

The present invention solves the above problems,
It is an object of the present invention to provide a highly practical ventilation port capable of surely guiding a liquid such as oil moving in the ventilation port to a liquid reservoir and preventing leakage of the liquid from the ventilation port.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention and will be described below.

The present embodiment is directed to a ventilation port a attached to a tube 1 having a ventilation function, and a cylindrical portion 2 fitted to the tube 1.
And a ventilation cylinder 5 which is detachably provided on the front side of the mounting cylinder 3 and has a liquid reservoir 8 at a lower portion thereof. Cylindrical liquid guiding portion 6 whose front end projects toward the front side of the
A liquid 12 such as oil in the pipe 1 or the ventilation port a flows down from the protrusion 7 on the front side of the liquid guide section 6 and is stored in the liquid storage section 8. It is.

The ventilation tube 5 is provided with a ventilation window 4 on the front side of the tube 5 '.
A ventilating plate 9 is provided, and a back side (a base end according to claim 4) is set in an opening 10, and a rising member 11 formed as a separate member is connected to the opening 10. The liquid reservoir 8 is formed below the ventilation tube 5 by a rising member 11.

In a general ventilation opening a, the ventilation tube 5 is provided with a ventilation plate 9 separately from the cylinder 5 'as in this embodiment, or the ventilation plate 5 is provided separately from the ventilation plate 5. 9 is provided integrally by press working or the like, but in any case, a rising member 11 is provided on the back side of the ventilation tube 5.
Can be easily formed.

The liquid guiding portion 6 has an external shape which can be fitted into the cylindrical portion 2. The drawing shows a case where the cylindrical portion 2 and the liquid guide portion 6 are circular in cross section.

In this case, the cylinder 2 and the liquid guide 6
When the liquid guiding portion 6 is fitted into the cylindrical portion 2, the projecting portion 7 of the liquid guiding portion 6 protruding from the cylindrical portion 2 has a directional characteristic of up, down, left and right in a front view. When the liquid guide portion 6 is assembled to the cylindrical portion 2, the liquid guide portion 6 does not need to be aligned with the cylindrical portion 2, and the assembling becomes easier. Further, since the liquid guiding portion 6 is cylindrical and fitted to the cylindrical portion 2, the outer surface of the liquid guiding portion 6 and the inner surface of the cylindrical portion 2 are in close contact with each other, and a gap is not formed as much as possible. Then, the liquid 12 is guided to the liquid reservoir 8.

At the tip of the projection 7 of the liquid guiding section 6, a tapered flange 13 which is curved in the outer peripheral direction is provided to allow the liquid 12 guided by the projection 7 to flow down well. Have been.

The mounting cylinder 3 and the ventilation cylinder 5 are connected by a detachable fastening member 14 such as a screw. According to this configuration, after the liquid 12 is stored in the liquid reservoir 8, the fastening member 14 is removed, and the ventilation cylinder 5 is removed from the mounting cylinder 3. Subsequently, the liquid 12 is stored in the liquid reservoir 8 of the ventilation cylinder 5. The liquid 12 is discarded by appropriate means, and then the ventilation tube 5 is attached to the attachment tube 3 again by the fastening member 14, and the liquid 12 is
Can be stored. Note that a structure other than the structure in which the attachment tube 3 and the ventilation tube 5 are attached and detached by the fastening member 14 may be employed.

In the drawing, reference numeral 15 denotes a wall, 16 denotes a side ventilation window provided on a side surface of the ventilation tube 5, and 17 denotes a fixing portion for fixing the tube portion 2 and the tube 1 in a pressed state.

The shapes of the tube portion 2, the mounting tube 3 and the ventilation tube 5 are cylindrical shapes as shown in the figure, but may be rectangular tube shapes, elliptical shapes, or the like. Is also good.

A container may be provided as a liquid reservoir 8 at a position below the liquid guiding portion 6, that is, at a position below the flange 13 of the projecting portion 7.

Since the present embodiment is constructed as described above, the liquid 12 such as oil generated from an indoor oil pan attached to the inside of the pipe 1 or the ventilation opening a is supplied to the liquid guiding section provided in the cylindrical section 2. 6, reaches the upper part of the liquid reservoir 8 provided at the lower part of the ventilation tube 5, and flows down from the protruding portion 7 of the liquid guiding portion 6. Since the liquid 12 does not pass through the connecting portion, the liquid 12 does not inevitably leak from the connecting portion, but is reliably guided and stored in the liquid storing portion 8, so that the liquid 12 leaks. Thus, the ventilation port a can be attached to a place such as an entrance where there is a traffic, so that the ventilation port a is excellent in practicability.

Further, the ventilation tube 5 is removed from the mounting tube 3,
By discarding the liquid 12 stored in the liquid storage section 8 of the ventilation tube 5, a highly practical ventilation port capable of reliably discarding the liquid 12 is provided.

Further, the liquid guide portion 6 for guiding the liquid 12 can be easily formed only by providing the liquid guide portion 6 on the inner surface of the cylindrical portion 2, and the existing ventilation port a can be easily modified. It becomes a ventilation port excellent in practicality and productivity.

The liquid reservoir 8 can be formed simply by providing a rising plate 11 in the opening 10 on the back of the ventilation tube 5, and the existing ventilation port a can be easily modified. It becomes a ventilation port with excellent practicality and productivity.

Recently, bathroom dryers that blow hot air into the bathroom to dry the bathroom have become widespread. After the use of the bathroom dryer, a large amount of water has accumulated in the pipe 1 and the ventilation port a. There is a problem that water adheres and the water flows out from the ventilation port a. In this case as well, the problem of the water outflow is solved by storing the water in the liquid reservoir 8 of this embodiment. can do.
