BACKGROUND OF THE INVENTION
The present invention relates to a ventilator that is attached to a sash door or the like and that can open and close a ventilation port by a sliding operation of an operation knob.
[0002]
[Prior art]
A conventionally known sash door-mounted ventilation device has an elongated structure to be installed at the upper edge or lower edge of the sash door, and the natural ventilation of the room with the sash door closed by this ventilation device. Can be done.
[0003]
A general ventilator is housed in a main body formed with a ventilation port and an operation window on the front wall facing the room, an operating plate arranged on the back side of the front wall and opening and closing the ventilation port, and an operation window on the front wall. And an operation knob slidable in the longitudinal direction of the main body. As the operating knob slides, the opening and closing operation of the ventilation port by the operating plate is performed. A back plate that covers the operation plate is attached to the back side of the main body. A vent hole is formed in the back plate. The main body and the back plate are formed of a metal such as an aluminum mold.
[0004]
In the conventional ventilation device described above, in the cold season, the back plate facing the outside air is cooled, and the heat of the main body is taken away by the back plate, so that the temperature of the front wall of the main body is lowered. There was a problem that condensation occurred when warm air contacted the front wall of the main body.
[0005]
In response to the above problem, the ventilator disclosed in Japanese Utility Model Publication No. 6-40872 includes an elongate front main body and a rear main body that are opposed to each other. These main bodies are connected to each other with a pair of resin connection members facing each other in the longitudinal direction and a pair of resin connection members facing each other in the width direction. An internal space is formed by the front main body, the rear main body, and the connecting members. Ventilation holes are formed in the front main body and the rear main body, and these ventilation openings are opened and closed by first and second operation plates. These operation plates are slidably supported along the front main body and the rear main body, respectively, and have vent holes. When these first and second actuating plates are in the slide position corresponding to the opening operation position of the operation knob, the ventilation holes are positioned so as to overlap the corresponding ventilation holes of the main body, so that ventilation can be performed. It has become. Further, when these first and second operation plates are in the slide position corresponding to the closing operation position of the operation knob, the respective ventilation holes are located at positions shifted from the corresponding ventilation holes of the main body. The internal space is a sealed space.
[0006]
In the closed state of the ventilation device, the outer main body and the inner main body are thermally blocked by the resin connecting member, and the air in the sealed inner space also functions as a heat insulating layer. For this reason, the cooled outer body does not take heat from the inner body, thus preventing condensation on the front body.
[0007]
[Problems to be solved by the invention]
In the above configuration, the first and second operation plates are opened and closed by sliding, and the adhesion between the operation plates and the front and rear bodies is not always good. Therefore, an elastic member made of rubber is interposed between these operation plates, and the adhesion between the operation plate and the main body is enhanced by utilizing the elastic force of this elastic member, and as a result, the internal space is sealed. . However, this elastic member is likely to deteriorate over time, and the hermeticity of the internal space deteriorates due to long-term use, which may cause condensation on the front body.
[0008]

Further, a support portion 16 extending in the longitudinal direction is formed on the rear surface of the inner body 10 so as to be positioned between the protrusion 14 a and the ventilation port 12 . A plurality of cam members 60 spaced in the longitudinal direction are fixed to the support portion 16. As shown in FIG. 5, a cam groove 61 is formed on the upper surface of the cam member 60. The cam groove 61 includes an inclined portion 61 a that is inclined with respect to the inner body 10, and parallel portions 61 b and 61 c that are formed at both ends of the inclined portion 61 a and are parallel to the inner body 10. The protrusion 42 of the first operating plate 40 is inserted into the cam groove 61 and guided.
[0022]
Slide guide grooves 25 and 26 are formed on the front surface of the outer body 20 so as to be positioned above and below the outer ventilation port 22. These slide guide grooves 25, 26 extend in the longitudinal direction of the outer body 20, and the upper and lower edges of the second operation plate 50 are fitted to be slidable in the longitudinal direction. As shown in FIG. 3, the second working plate 50 is formed with the same number of vent holes 51 having the same shape as the vent holes 22 of the outer body 20 at the same pitch as the vent holes 22.
[0023]
The ventilation device further includes an operation knob 70. The operation knob 70 has a knob body 71 and a back plate 72. The front end of the knob body 71, the operation window 11 of the inner body 10, which is longitudinally slidably received, is slightly projecting from the inner body 10. Knob body 71 by being fitted into the fitting hole formed in the center of the first actuating plate 40 (not shown), which cooperate with the first operation plate 40. An engagement recess 71a is formed on the rear surface of the knob body 71, and an engagement member 55 fixed to the front surface of the second operation plate 50 is fitted in the engagement recess 71a. Thereby, the operation knob 70 is also linked to the second operation plate 50. In addition, you may improve the sealing performance between the operation knobs 70 by providing packing in the periphery of the fitting hole of the said 1st action | operation board 40. FIG.
As shown in FIG. 2, the back plate 72 of the operation knob 70 covers the operation window 11, and “open” and “closed” are displayed on the left and right portions of the front surface thereof. .
[0024]
A sash window glass 100 is fitted between the lower end portions between the inner main body 10 and the outer main body 20 via a cushioning material 101. In this example, the window glass 100 is a double glass that is held at a distance by a bridge 102.
[0025]
In the ventilator configured as described above, when the operation knob 70 is slid rightward in FIG. 1 until the knob body 71 hits the right end of the operation window 11 (opening operation position), the first operation plate 40 slides in the same direction. To do. At this time, as shown in FIG. 5, the cam follower 42 of the first working plate 40 is guided by the cam groove 61 of the cam member 60, and reaches the parallel portion 61c from the parallel portion 61b through the inclined portion 61a. As a result, the first working plate 40 is rotated from the closed position in FIG. 1A to the open position in FIG. 1B to be separated from the inner body 10, and the ventilation port 12 of the inner body 10 is opened.
[0026]
When the operation knob 70 is slid to the opening operation position, the second operation plate 50 linked to the operation knob 70 is also slid in the same direction. As a result, the vent hole 51 of the second working plate 50 overlaps with the vent hole 22 of the outer main body 20, and the vent hole 22 is opened.
As described above, since the ventilation ports 12 and 22 of the inner main body 10 and the outer main body 20 are opened, indoor and outdoor air is ventilated through the ventilation ports 12 and 22 and the internal space 35.
[0027]
Contrary to the above, when the operation knob 70 is slid in the left direction in FIG. 1 until the knob body 71 hits the left end of the operation window 11 (closed operation position), the first operation plate 40 slides in the same direction. At this time, as shown in FIG. 5, the cam follower 42 of the first working plate 40 is guided by the cam groove 61 of the cam member 60 and reaches the parallel portion 61b from the parallel portion 61c through the inclined portion 61a. As a result, the first operating plate 40 rotates from the open position in FIG. 1B to the closed position in FIG. 1A to contact the inner body 10 and the ventilation port 12 of the inner body 10 is closed. In addition, packing may be provided in either one of the longitudinal direction both ends edge of the 1st action | operation board 40, and the inner surface part of the inner side main body 10 corresponding to this, and it may be made to contact both via packing in the said closed state. Further, packing may be provided on either the lower end edge of the first working plate 40 or the inner surface portion of the inner body 10 corresponding thereto.
[0028]
When the operation knob 70 is slid to the closing operation position, the second operation plate 50 linked to the operation knob 70 is also slid in the same direction. As a result, as shown in FIG. 3, the vent hole 51 of the second working plate 50 is shifted from the vent hole 22 of the outer body 20, and the vent hole 22 is closed by the second actuating plate 50.
[0029]
As described above, since the ventilation ports 12 and 22 of the inner main body 10 and the outer main body 20 are closed, ventilation inside and outside the room is blocked.
In the closed state, since the caps 31 and 32 made of resin and the bridges 33 and 34 made of resin are interposed between the inner main body 10 and the outer main body 20, the heat transfer between the main bodies 10 and 20 is prevented. It is shut off. Moreover, since the internal space 35 is sealed, the air in the internal space 35 becomes a heat insulating layer. As a result, it is possible to prevent the outer body 10 that is exposed to cold outside air during the cold season from taking heat away from the inner body 20, and it is possible to prevent condensation from forming on the inner body 20.
[0030]
In the closed state, the first operating plate 40 reliably contacts the inner main body 10 using the cam action of the cam member 60, so that the sealing performance between the two is high. On the other hand, the second operation plate 50 is a slide type, and the sealing property between the second operation plate 50 and the outer body 20 is between the swing type first operation plate 40 and the inner body 10. Inferior to sealability. However, as described above, the sealing performance between the first working plate 40 and the inner main body 10 is high, and air is blocked from flowing between the internal space 35 and the room. Can be prevented from flowing through a slight gap between the second working plate 50 and the outer main body 20. As a result, the airtightness of the internal space 35 is sufficiently enhanced, and the role as a heat insulating layer can be sufficiently fulfilled.
In the said embodiment, since the 2nd action | operation board 50 was made into the slide type | mold, the space of rocking | fluctuation becomes unnecessary and a ventilation apparatus can be made thin.
[0044]
【The invention's effect】
As described above, according to the first aspect of the present invention, the inner main body and the outer main body are bridged by a resin-made connecting member having low thermal conductivity, and the inner main body, the outer main body, and the connecting member are formed. The internal space is sealed with the ventilation port closed, and the air in this internal space is used as a heat insulation layer, so that the outer body cooled by the outdoor cold air does not take heat from the inner body, and condensation on the inner body is prevented. Can be prevented. In addition, since the first operating plate is a swinging type and can be brought into close contact with the inner body using a cam action, the degree of sealing of the internal space can be increased, and as a result, the heat insulating effect of the ventilation device can be further enhanced. Thus, the condensation can be surely prevented. Moreover, the ventilation device can be made thin by using the second operating plate as a slide type.
