[0002]

2. Description of the Related Art In recent years, high airtightness and high heat insulation of houses have progressed, and if sufficient ventilation is not provided, the concentration of carbon dioxide becomes too high. In particular, in new houses, formaldehyde and volatile organic compounds (VOCs) are used. Composition)
May become too high. In addition, poor ventilation can increase the humidity and cause mold and mite, which can cause allergies.

[0003] In order to solve this problem, the inventors of the present invention have previously devised and applied for a "ventilation structure for houses" (Japanese Patent Application No. 10-88329, unpublished). Hereinafter, this ventilation structure is referred to as a “24-hour ventilation system”.

As shown in FIG. 6, this 24-hour ventilation system is provided at a substantially central part of a house (for example, an apartment) which is kept airtight, and has a central exhaust device 1 for directly exhausting room air to the outside, And a communication air supply hole 2 provided on an outer wall in contact with the outside air and communicating the outside air with the room. The central exhaust device 1 forms an air cycle that flows from the communication air supply hole 2 through the room to the outside, and is operated continuously at a low air flow with sufficiently low noise. Therefore, with this configuration, an air cycle in which the outside air from the air supply hole flows through the room to the outside by the low flow rate of 24 hours of ventilation is formed, and the concentration of indoor contaminants is suppressed to a low level with almost no noise. Can be.

However, also in this case, since the duct from the exhaust device is directly adhered or taped to the ventilation register, it is difficult to install / remove the duct, and the interior cannot be inspected or cleaned by a layman. (2) In the conventional ventilation register 7 shown in FIG. 7, by turning a knob 7a protruding to the center with a finger, one of the two sets of ventilation fans is swung inside to change the opening area, thereby reducing the air supply flow rate. Had to adjust. However, knob 7
Since a protrudes toward the indoor side, the knob 7a is often damaged by furniture or the like when installing furniture or the like, or the knob 7a is difficult to operate because it is hidden by furniture. (3) The conventional ventilation register has a structure in which the inside can be directly seen from the opening. As a result, the interior heat insulating material was visible, and the interior dirt and the blackened filter were directly visible, sometimes damaging the interior. (4) In order to prevent dust and pollen from entering, it is desirable to attach a filter to the ventilation register. But,
When a filter is attached to the conventional ventilation register 7,
The adjustment mechanism of the supply air flow becomes complicated, and on the contrary, it becomes difficult to replace the filter.

The present invention has been made to solve the various problems described above. That is, a main object of the present invention is to provide a ventilation register which can be easily installed / removed even by a layman, and which can easily perform internal inspection and cleaning. Another object of the present invention is to provide a ventilation register which does not have a projection which is easily damaged by furniture or the like and which is easy to operate even if it is hidden by furniture. Still another purpose is, by combination, the inside can be easily not seen,
