Description

  The present invention relates to a ventilator for actively ventilating indoor air through a gap between a rail and a door in a rail-type door.

  In order to ventilate a sealed room, a resident or a manager of the room turns a normal ventilation fan or opens and closes a door as appropriate. However, when leaving the house, the door is locked and the ventilation fan is turned off, so that moisture and odor cannot be discharged. However, there is currently no solution to this, and the fact is that long-term absentees have no choice but to go there occasionally to open the door and ventilate.

  The ventilators currently on the market are not designed on the assumption that they will be left on for a long time, and even if they can be left on for a long time, there is a problem that the electricity cost for that purpose increases.

  Of the commercially available ventilation fans, even if a small one is used, a hole must be drilled in the wall, and if it is close to the ceiling, the traditional ventilation fan installation location, The warm air in the upper part of the house will be discharged, and it will not be appreciated from the viewpoint of thermal efficiency in the winter season for those who live there.

  An object of the present invention is to provide a novel ventilation device capable of always and safely ventilating a room with an appropriate ventilation amount with a window closed without newly making a hole in the wall for installing a ventilation fan. The point is to provide.

  The present invention is a simple, inexpensive and safe ventilator based on a completely new concept of using indoor air as a ventilation hole in a gap between a rail and a door in a rail type door.

A first aspect of the present invention relates to a ventilating apparatus comprising an elongated space portion formed along a lower portion of a door frame on the indoor side of a rail opening / closing door, and a ventilation fan installed in the space portion.
The second aspect of the present invention includes an elongated space formed along the lower part of the door frame on the indoor side of the rail opening / closing door, a ventilation fan box containing the ventilation fan, and a communicating member between the space and the ventilation fan box. It is related with the ventilation apparatus characterized by becoming.
3rd of this invention is related with the ventilator of Claim 1 or 2 made detachable with respect to the rail opening-and-closing type door.
4th of this invention is related with the ventilator in any one of Claims 1-3 whose said door frame is a door frame of the 2nd sliding door counted from the indoor side at least among several sliding doors.

The “elongated space portion formed along the lower part of the door frame on the indoor side of the rail opening and closing door” of the present invention is a space for taking indoor air into the elongated space portion, and the taken-in air is a rail. The space between the door with the rail in the door and the door can be used as a vent hole, and the indoor air taken in can be forcibly discharged from here using the power of the ventilation fan.
This elongated space is usually a sliding door with one or two other sliding door rails inside the sliding door as viewed from the indoor side, and the door frame and sill on the lower side of the sliding door Although the space part which can be provided in the middle is pointed out, the space part which can be provided between the door frame and the sill of the lower side part of 2 to 3 sliding doors may be used. However, the purpose of ventilation can be sufficiently achieved if the house is of a normal size by providing the ventilation device of the present invention only on one door frame.

The width of the door frame (the lower side door frame) is about 3 cm for narrow ones, usually about 5 to 7 cm, and the width of one door (in the rail direction) is about 50 to 100 cm. The bottom edge of the sliding door (door frame) is at the bottom of the elongated space, the width of the door frame at the lower side or slightly smaller is the height of the elongated space, and the raised end of the sill The predetermined space between the door frame and the door frame is the depth of the elongated space portion. Accordingly, the bottom and height of the elongated space portion are constant, but the depth is naturally different between the first sliding door and the second sliding door. However, in the present invention, even if there is only one sliding door or a plurality of sliding doors, the object can be sufficiently achieved if the ventilation device of the present invention is set in the portion of one of the sliding doors. Further, a plurality of sliding door portions can be the subject of the present invention as necessary.
Since it is efficient to ventilate indoor air only between the target sliding door (for example, sliding door A in FIGS. 1 to 4) and the rail, the target sliding door (for example, sliding door A) It is preferable to prevent air from entering and exiting from the gap between the adjacent sliding door (for example, sliding door B) and the rail. For this purpose, as shown in FIG. 2, at least between the sliding door B and the elongated space portion of the present invention, for example, by means of an end sealing member, “the elongated space portion provided on the sliding door A side” and “sliding door B And the “gap between the rails” are preferably cut off.

As shown in FIG. 3, the ventilator of the present invention is attached to the sliding door (the sliding door A in FIGS. 1 to 4) on the side having a space equivalent to one sliding door in principle. Is preferred.
Further, in order to prevent air from entering and exiting along the lower side of the sliding door B from the rail gap portion on the sliding door B side, a sealing plate member for the sliding door B (in the space between the sliding door B and the sill ( For example, it is preferable to insert the one having the structure shown in FIG.

  As a specific means for forming the elongated space portion, for example, a space is formed between the sliding door and the sill using an inverted L-shaped member having an L-shaped cross section and a length corresponding to the length of the sill, Elongated spaces can be formed at both ends by using sealing plate-like members, respectively. If the contact portion between the column and the inverted L-shaped member can maintain a sufficient seal on the column side, the sealing plate member is not necessary. Of course, the portion corresponding to the ceiling of the inverted L-shaped member that corresponds to the ceiling of the elongated space portion naturally corresponds to the depth. Further, in the case of the front sliding door (sliding door B in FIGS. 1 to 4) when viewed from the room, when the distance (gap width) between the door frame and the sill edge is very short (narrow), FIG. As shown in FIG. 4, the ceiling equivalent portion can be used as a seal member. Further, when the distance is short, a plate-like elastic body or an elastic-coated metal plate can be used.

  Examples of the material forming the inverted L-shaped member and the plate-like member include synthetic resin, elastic body, wood, metal, and a laminate thereof. And it is preferable to attach the sealing member in the part which these contact with a door frame or a sill. An elastic material such as rubber or rubber sponge can be used as the sealing member. The ventilator of the present invention must be detachable as viewed from the place where it is attached, and this sealing member is easy to attach and detach, and function loss due to deformation or the like hardly occurs even after many attachments and detachments. A shape is preferable.

  Although the ventilation fan can be directly attached to the elongated space portion, a ventilation box containing the ventilation fan is separately prepared, for example, on the wide side portion of the ceiling of the elongated space portion or the indoor side wall of the elongated space portion. It can also be attached. In this case, it is preferable that the convex air blowing hole provided in the ventilation box is connected to the hole provided in the ceiling of the elongated space. The convex air blowing hole portion corresponds to a communicating member between the sealed space portion and the ventilation fan box described in claim 2. In addition, although one example of the ventilation fan box was shown in FIG. 9, the ventilation fan box may have such a rectangular parallelepiped shape, or may have a cylindrical shape. The ventilation fan box is preferably made of a heat insulating material in consideration of summer sunlight and winter cold air.

  The ventilation fan used for this invention can divert the small fan motor (usually for 5-15V) currently used for internal cooling, such as a personal computer. This small fan motor (usually for 5 to 15 V) can be driven from a household power source through a commercially available transformer, and is safe even for long-term continuous operation. With this degree of ventilation fan, it is possible to exhaust air of 6 to 10 cubic rice per hour.

(1) According to the present invention, the room can be ventilated in a necessary and sufficient range even if the user is absent for a long time.
(2) The ventilator of the present invention is small and does not disturb the aesthetics of the room.
(3) Since the ventilator of the present invention is of the type attached to the lower part of the window frame, the conventional exhaust fan can avoid energy loss due to exhausting a large amount of warm air present in the upper part of the room, Moreover, since the temperature difference between the upper and lower air in the room can be reduced, the living comfort is improved for the residents living in this room.
(4) The ventilator of the present invention uses power that is orders of magnitude smaller than conventional ventilators, and the noise associated with rotation is also small.
(5) Gap wind entering from the rail part of the sliding door is very unpleasant in winter, but this gap wind can be blocked by installing the device of the present invention.
(6) Since an appropriate amount of ventilation is always performed, the occupant's spatial environment can be suitably maintained, and the risk of carbon monoxide poisoning due to carelessness and the like can be reduced.

  Hereinafter, the present invention will be described with reference to examples, but the present invention is not limited thereto.
