That is, this door ventilation structure is configured by providing a lid 1 on an entrance/exit door 10 provided between a toilet 21 and a corridor 22 adjacent to the toilet 21 .

The lid 1 is provided in an opening 10a having a diameter of about 110 mm which is bored through the entrance door 10. As shown in FIG. The lid body 1 is composed of an opening member 11, a lid piece 12, and a ventilation lid 13, and is designed to allow ventilation from the corridor 22 to the toilet 21 through the ventilation path 30 and prevent ventilation from the toilet 21 to the corridor 22. ing. The opening member 11, the lid piece 12, and the ventilation lid 13, which constitute the lid body 1, are each or partially made of a resin material having optical transparency, or a composite of a metal material and a resin material having optical transparency. made up of materials.

The opening member 11 is configured by providing a cylindrical portion 11c formed in a cylindrical shape on one side of a disc-shaped flange surface 11b provided with a ventilation slit 11a. The cylindrical portion 11c is formed in a substantially cylindrical shape that can be inserted into the opening 10a formed in the entrance door 10. As shown in FIG. An inclined surface 11d is provided in the cylindrical portion 11c. The inclined surface 11d is inclined so that the lower side is located near one end of the cylindrical portion 11c and the upper side is located near the flange surface 11b, blocking the inside of the cylindrical portion 11c. A columnar partition 11e is left in the center of the inclined surface 11d, and semicircular openings 11f are formed on both sides thereof.

The lid piece 12 is formed in a substantially semicircular shape that is one size larger than the opening 11f provided in the cylindrical portion 11c of the opening member 11, and projections 12a are provided above and below in the diametrical direction along the section. . The lid piece 12 is attached by fitting projections 12a to support portions 11g provided above and below the partition portion 11e of the inclined surface 11d, and is provided on the inclined surface 11d so as to block the opening 11f. When negative pressure is generated in the toilet 2a, the lid piece 12 opens the opening 11f around the straight line connecting the protrusions 12a as a rotation axis, opens the ventilation path 30, and when the negative pressure is eliminated, the cover piece 12 is self-weighted. The ventilation path 30 is closed by closing the opening 11f.

The opening 11f can be closed immediately. The extent to which the lid piece 12 opens or closes in response to the negative pressure is adjusted according to the degree of inclination of the inclined surface 11d, the material of the lid piece 12, the thickness of the thickness preserving portion 12b, and the like. be able to.

The ventilation lid 13 is constructed by providing a substantially ring-shaped fitting portion 13c fitted to the tip of the cylindrical portion 11c of the opening member 11 on one side of a disc-shaped flange surface 13b provided with a ventilation slit 13a. there is

Next, a method of attaching this lid 1 to the entrance/exit door 10 of the toilet 21 of the residential building 2 shown in FIG. 5 will be described.

In FIG. 5, 21 is a toilet, 22 is a corridor, 23 is an entrance hall, 24 is an entrance, 25 is a staircase, and 26 is a living room. This layout is just an example.
First, an opening 10a is drilled in the entrance door 10 prior to installation. At this time, the opening 10a may be drilled at any position of the entrance door 10 in particular.

Next, the cylindrical portion 11c of the opening member 11 is inserted from the corridor 2b side of the opening 10a drilled in the entrance door 10, and the ventilation lid 13 is brought into contact with the toilet 2a side of the opening 10a to open the cylinder of the opening member 11. The portion 11c and the ventilation lid 13 are fixed with screws 14. As shown in FIG.

At this time, the opening member 11 is fixed so that the lower side of the inclined surface 11d is positioned on the toilet side 21 in the cylindrical portion 11c and the upper side is positioned on the corridor 22 side.

According to the door ventilation structure in which the lid 1 is provided on the doorway door 10 in this manner, when the window 21a of the toilet 21 is opened to ventilate the toilet 21, the ventilation path 30 of the lid 1 will flow into the toilet 21. The inside of the toilet 21 can be efficiently ventilated by letting the air taken in through the window 21a. That is, when the wind blows outside the window 21a, the inside of the toilet 21 becomes negative pressure, and this negative pressure causes the lid piece 12 of the lid 1 to open the opening 11f, thereby opening the ventilation path 30 and the inside of the toilet 21. This air is ventilated to the outside through the window 21a.

Further, even if the wind blows into the toilet 21 due to a bad wind direction when the window 21a is opened, the opening 11f of the lid body 1 is closed by the lid piece 12. The odor of the toilet 21 can be prevented from flowing into the corridor 22 via the lid 1. - 特許庁Therefore, it is possible to prevent the odor of the toilet 21 from deteriorating the environment in the house.

Furthermore, when the door 10 of the toilet 21 is opened with the window 21a of the toilet 21 closed, the door 10 becomes heavy due to air resistance when the door 10 is opened because the toilet 21 is closed. Since the opening 11f is opened by the lid piece 12 and the air is released through the ventilation path 30 of the lid 1, the entrance door 10 can be easily opened without feeling air resistance.

In addition, since the lid body 1 has a light transmittance, when a person is in the toilet 21 and the lighting is turned on, the light of the lighting is transmitted to the corridor 22, so that the corridor is illuminated. The presence of a person in the toilet 21 can be determined from the 22 side. Therefore, it is possible to prevent a person on the corridor 22 side from coming into contact with the door opened from the toilet 21 side and being injured.
