Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air supply hole structure for introducing outside air into a room through a wall or exhausting room air, and more particularly to a ventilation register thereof.
[0002]
[Prior art]
In recent years, houses have become highly airtight and highly insulated, and the carbon dioxide concentration becomes too high unless sufficient ventilation is provided. Especially in newly built houses, the concentration of formaldehyde and volatile organic compounds (VOC) is high. May be too high. In addition, inadequate ventilation can result in high humidity, mold and ticks, and allergies.
[0003]
In order to solve this problem, the inventors of the present invention previously created and filed a “house ventilation structure” (Japanese Patent Application No. 10-88329, unpublished). Hereinafter, this ventilation structure is referred to as a “24 hour ventilation system”.
[0004]
As shown in FIG. 6, the 24-hour ventilation system includes a central exhaust device 1 that is installed in a substantially central part of a house (for example, a condominium) that is kept airtight and exhausts indoor air directly to the outside, and an outer wall that is in contact with the outside air. And a communication air supply hole 2 that communicates between the outside air and the room. The central exhaust system 1 forms an air cycle that flows from the communication air supply hole 2 to the outside through the room, and continuously operates with a low air volume with sufficiently low noise. Therefore, with this configuration, low-flow 24-hour ventilation forms an air cycle in which the outside air from the air supply holes flows through the room to the outside, and the concentration of indoor pollutants is kept low with almost no noise. Can do.
[0005]
[Problems to be solved by the invention]
7A and 7B are structural views of a conventional communication air supply hole 2. FIG. 7A is a cross-sectional view, and FIG. 7B is a right side view. As shown in this figure, a conventional air supply hole 2 includes an embedded sleeve 4 (referred to as a “concrete driving sleeve”) embedded in an outer wall 3 in contact with the outside air, a joint sleeve 5 inserted into the inner surface of the embedded sleeve 4, It consists of a ventilation gallery 6 attached to the outer end of the sleeve and a ventilation register 7 attached to the inner end of the joint sleeve 5.
[0006]
The buried sleeve 4 is usually a cylindrical tube made of vinyl chloride having a length substantially equal to the thickness of the outer wall 3 and is buried when the outer wall concrete is driven. The joint sleeve 5 is fixed to the embedded sleeve 4 with an adhesive or the like, and has a function of closing a gap to the attachment surface (inner wall surface) of the ventilation register 7. The ventilation louver 6 is attached to the inner surface of the buried sleeve with packing and caulking material, and introduces air supply while preventing rainwater from entering. Furthermore, the ventilation register 7 usually adjusts the supply air flow rate by swinging one of the two sets of ventilation fans to change the opening area.
[0007]
However, the conventional air supply hole structure described above, particularly the ventilation register 7, has the following problems.
(1) Since the ventilation register 7 is attached by an adhesive, packing, caulking material, etc., it is difficult for an amateur to attach / remove, and the inside cannot be inspected or cleaned. In other words, the conventional ventilation register has a structure that is simple and inexpensive to manufacture because the outer periphery of the casing is directly attached to the wall with an adhesive or the like. It was also difficult to re-attach using the etc.
Moreover, what enlarged the said ventilation register is attached to the ceiling etc. as a ventilation inlet for exhausting indoor air. However, in this case as well, the duct from the exhaust device is directly bonded or taped to the ventilation register, so that it is difficult to attach / remove, and an amateur cannot check or clean the inside.
(2) In the conventional ventilation register 7 shown in FIG. 7, by turning the knob 7a protruding in the center with a finger, one of the two sets of ventilation fans is oscillated inside to change the opening area, thereby changing the supply air flow rate. It was supposed to adjust. However, since the knob 7a protrudes indoors, the knob 7a is often damaged by the furniture or the like when the furniture is installed, or the knob 7a is difficult to operate because it is hidden behind the furniture.
(3) The conventional ventilation register has a structure in which the inside can be directly seen from the opening. As a result, the internal heat insulating material can be seen, the internal dirt and the black filter can be directly seen, and the interior may be damaged.
(4) In order to prevent intrusion of dust and pollen, it is desirable to attach a filter to the ventilation register. However, if a filter is attached to the conventional ventilation register 7, the supply air flow rate adjustment mechanism becomes complicated, and conversely, it becomes difficult to replace the filter.
[0008]
The present invention has been made to solve the various problems described above. That is, the main object of the present invention is to provide a ventilation register that can be easily attached / detached even by an amateur and can be easily inspected and cleaned. Another object of the present invention is to provide a ventilation register that does not have projections that are easily damaged by furniture or the like and that is easy to operate even when hidden behind the furniture. Still another object is to provide a ventilation register that can be easily looked into the interior and can be easily mounted and replaced by a combination.
