Description

  The present invention relates to a ventilation structure in which a ventilation frame is provided between a living room side and a hallway side in a door frame provided between a living room and a hallway and disposed around a door opening that is opened and closed by a door. .

  In order to prevent sick house syndrome caused by formaldehyde, VOC (volatile organic compounds), etc., due to high airtightness of houses, it is necessary to secure a ventilation rate above a certain level. High ventilation standards are required to maintain and improve the living environment. Moreover, in these ventilation standards, the whole house is regarded as a single space. For example, when ventilating the air in the room from the room through the corridor and from the mechanical ventilator of the toilet, a certain amount of ventilation is secured in the opening that is provided between the room and the corridor and can be opened and closed by fittings. It is necessary to.

  When a fitting with a relatively large gap in its structure itself, such as a sliding door or a folding door, is used as a ventilation path as it is because the ventilation amount is obtained above a certain level. On the other hand, when using a door, it has excellent airtightness. Therefore, a ventilation louver is provided on the partition wall around the door body or the door opening, or an undercut is formed with a height of about 1 cm to ensure the necessary ventilation. There is a need. However, these ventilation louvers and undercuts have a problem that the appearance at the entrance / exit of the living room, where interior finishing is important, gives a sense of incongruity and impairs the appearance.

  In order to solve this type of problem, as shown in FIG. 6, a door frame c having an air passage d through which air can flow is attached to the inner surface of a door opening b to which the door a is attached, and the door frame c By providing a substantially L-shaped decorative edge g projecting from the surface f of the wall e between the wall e and the wall e, the decorative edge g is provided on both decorative edges g and g and opens toward the outside of the door opening b. There has been proposed a ventilation structure in which both vent holes h and h are communicated with each other via an air passage d of the door frame c (see, for example, Patent Document 1).

  And in this ventilation structure, since the air which flowed in from the ventilation hole h of one decorative edge g flows into the opening h of the other decorative edge g through the air passage d of the door frame c, the door a is closed. In this case, ventilation can be ensured between the spaces on both sides of the door opening b.
