Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a ventilator that closes and opens ventilation holes that allow air to be ventilated on the indoor side and the outdoor side, and allows indoor ventilation as necessary.

[0002]

[Prior art]

 Generally, in a highly airtight house, it may be necessary to replace indoor polluted air with fresh outdoor air. Therefore, it is known that a ventilation hole is provided for allowing ventilation between the indoor side and the outdoor side for ventilation. Further, while the ventilation holes can take in fresh outdoor air indoors, outdoor humidity and noise also flow into the indoor areas, so a ventilation device that closes the ventilation holes when ventilation is unnecessary is provided. It is provided.

Conventionally, it is known that a window frame such as an aluminum sash built in an outer wall is integrally provided with a ventilation hole and a ventilation device. As a result, ventilation can be achieved simply by incorporating a window frame such as an aluminum sash into the outer wall.Therefore, there is no need to make holes for ventilation holes in the outer wall, which facilitates the construction work and makes the outer wall itself highly insulated. Can maintain sex.

This type of ventilator has an outer plate fixed by being fitted into an opening (corresponding to a ventilation hole) formed along one side (for example, an upper edge) of the window frame, and is superposed on the outer plate. It is composed of an inner plate slidably provided. The outer plate is formed with a plurality of holes at predetermined intervals along the moving direction of the inner plate, and the inner plate has a plurality of holes at predetermined intervals corresponding to the holes of the outer plate. Is formed. When the inner plate is slid in one direction, the holes in the inner plate are aligned with the holes in the outer plate to allow ventilation, and when the inner plate is slid in the other direction, the space between the holes in the inner plate is reduced. It is possible to block the air flow by closing the holes of the outer plate.

However, according to this type of ventilation device, the original ventilation amount of the opening is largely restricted by the space between the holes of the outer plate, and a relatively large opening is formed in the window. The disadvantage is that the ventilation efficiency is low. Further, in this type of ventilator, since the space between the holes of the inner plate closes the hole of the outer plate to close the opening, the degree of adhesion between the outer plate and the inner plate in the overlapping state is low. In this case, there is the inconvenience that the outside air enters the room through the space between the outer plate and the inner plate and the airtightness of the room is impaired. Furthermore, if the degree of adhesion between the outer plate and the inner plate is improved and the opening is surely closed, friction resistance with the outer plate occurs when sliding the inner plate, and It is difficult to open and close.

[0006]

[Problems to be solved by the device]

 By eliminating such inconvenience, the present invention is a ventilation device suitable for being incorporated in a window frame, and it is possible to obtain a relatively large amount of ventilation when the ventilation hole is opened and to ensure the ventilation hole. It is an object of the present invention to provide a ventilation device that has a simple structure and can be closed and that can be easily opened and closed.

[0007]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides a ventilation device which is provided in a ventilation hole that allows ventilation between the indoor side and the outdoor side, and which ventilates indoors by opening the ventilation hole in a freely blockable manner. A closing member that abuts one opening of the ventilation hole to close the ventilation hole; and a ball screw that is rotatably supported by the closing member and is immovable in the axial direction and extends toward the inside of the ventilation hole. A fixing member fixed to the inside of the ventilation hole and having an insertion hole into which the ball screw is inserted, and by rotating the ball screw of the closing member inserted into the fixing member, The closing member is moved via the ball screw, and the closing member is brought into contact with one opening of the ventilation hole or the distance between the opening and the closing member is adjusted according to the rotation direction of the ball screw. To do.

According to the present invention, by rotating the ball screw which is screwed into the insertion hole of the fixing member, the closing member is moved away from the opening of the ventilation hole or in the direction of contacting the opening of the ventilation hole. Can be moved to.

That is, when the vent hole is opened, the blocking member can be moved in a direction away from the opening of the vent hole only by rotating the ball screw in the direction of moving from the vent hole to the indoor side. At this time, the moving distance of the ball screw is proportional to the number of rotations, and the closing member widens the gap from the opening of the vent hole according to the moving distance of the ball screw. Can be opened relatively large, and sufficient ventilation efficiency can be obtained according to the size of the ventilation hole. Therefore, for example, even with a vent hole formed in a limited range such as a window frame, it is possible to obtain as much air flow rate as possible from the vent hole. In addition, by rotating the ball screw little by little, the distance that the blocking member separates from the opening of the ventilation hole can be finely adjusted, so that the desired flow rate of air during ventilation can be easily adjusted. it can.

Further, when closing the vent hole, the ball screw is rotated in a direction of entering the vent hole. The closing member follows the entry of the ball screw and approaches the opening of the ventilation hole, and then comes into contact with the opening of the ventilation hole to reliably close the ventilation hole.

Further, in the present invention, the fixing member has a pair of close contact surfaces that are in close contact with a part of inner walls of the ventilation hole that face each other, and the fixing member can be inserted into the ventilation hole and has a substantially rectangular tubular shape. Body, a claw member made of a metal plate housed in the body and provided at both ends thereof so as to be projectable from both contact surfaces, and a collar portion locked to an edge of one opening of the ventilation hole. The claw member is formed in a substantially dogleg shape having a bent portion in a substantially central portion, and both end edges are inclined from the bent portion toward the insertion direction of the fixing member main body while vent holes are provided. It is characterized by protruding toward the inner wall of the.

The fixing member is fixed in the ventilation hole by being pushed into the ventilation hole until the flange is locked to the edge of one opening of the ventilation hole. When both the contact surfaces of the fixing member rub against each other along the inner wall of the ventilation hole, the edges of the claw members protruding from the both contact surfaces of the fixing member are caught on the inner wall of the ventilation hole. Then, when the fixing member is further pushed in, the angle of the bent portion of the claw member widens, and at the same time, the protruding amount of both end edges increases and bites into the inner wall of the vent hole. With this, the fixing member can be fixed in the ventilation hole only by pushing it into the ventilation hole.

Further, the vent hole is a rectangular square hole, the blocking member has a shape corresponding to one opening of the vent hole, and the blocking member extends toward the inside of the vent hole. It is characterized in that it is provided with a guide portion for inserting the closing member in the closing direction of the ventilation hole in a state of being in contact with a part of the inner wall of the ventilation hole.

The closing member is brought into contact with or separated from the ventilation hole by rotating the ball screw as described above. At this time, the ball screw is rotatably provided on the closing member, but the closing member easily rotates as the ball screw rotates. In particular, when the ventilation hole is a rectangular square hole and the blocking member has a shape corresponding to the opening, the blocking member is inadvertently rotated and the opening of the ventilation hole cannot be reliably blocked. There is a risk. Therefore, by extending the guide portion to the closing member, the guide portion is brought into contact with the inner wall of the ventilation hole to guide the movement of the closing member, thereby preventing an inadvertent rotation of the closing member. In addition, the opening of the ventilation hole can be reliably closed.

Further, in the ventilator of the present invention, the ventilation hole is a rectangular quadrangular hole, a ventilation member is provided at the other opening of the ventilation hole, and the cover member is A communication port connected to the other opening of the vent hole, an upper wall plate protruding outward from an upper edge of the communication port, and a communication port connected to both side edges of the upper wall plate. , A pair of side wall plates facing each other from both side edges of the communication port and projecting in the same direction as the upper wall plate, and a front edge and both side walls of the upper wall plate facing the opening to which the communication port is connected. It comprises a counter wall plate connected to the leading edge of the plate, and a ventilated louver provided in an opening formed by being surrounded by the lower edges of both side wall plates and the counter wall plate. It is characterized by

[0016] Thus, the upper wall plate, both side wall plates and the opposing wall plate of the cover member can prevent wind and rain from entering through the other opening of the ventilation hole, and lower edges and opposite sides of the both side wall plates. Through the opening surrounded by the lower edge of the wall plate, invasion of dust and pests can be prevented without obstructing ventilation.
