As shown in FIG. 3, a through hole is provided in the wall W, and a piping duct D is fitted into the through hole. Positioning is performed so that the vent 2a of the main body 2 enters the pipe duct D, and the main body 2 is fixed to the wall W. Then, the main body cover 3 is moved from the X direction to the Y direction toward the main body 2 so that the back surface of the main body cover 3 covers the front surface of the main body 2 as described above.

  Although various methods can be employed for fixing both, in the air supply shutter 1 according to the embodiment of the present invention, the fitting member 3b of the main body cover 3 is attached to the projection 2b provided on the upper portion of the main body 2. The main body cover 3 and the main body 2 are fixed to each other at the lower part of the main body 2 using a fixing member 9a.

  As shown in FIGS. 2 and 3, the main body 2 is provided with a vent 2 a that projects into the pipe duct D in the Y direction. When the room is in a state of negative pressure than the outdoor due to the operation of the kitchen range hood or the like, the outside air is supplied into the room through the vent 2a.

  A mounting base 2d is further formed in the X direction in the main body frame 2c formed continuously with the vent 2a. The mounting base 2d is formed over substantially the entire circumference of the front surface of the main body 2 avoiding a region where a panel opening / closing motor, which will be described later, is disposed, and a region storing other devices. The mounting base 2d improves the strength of the main body frame 2c, and creates a storage space for the cap 5 and the cap retainer 6 when the cap 5, the cap retainer 6, and the body cover 3 fitted with the filter 7 are fitted together. Formed for.

  Further, a sealing material 2e is stretched over the entire front surface (X direction) of the mounting base 2d. As will be described later, when the main body cover 3 is attached to the main body 2, the main body cover side rib of the main body cover 3 comes into contact with the sealing material 2e.

  As shown in FIG. 2, an operation member 10 is provided in the central portion surrounded by the mounting base 2 d of the main body 2 so as to be parallel to the wall W to which the air supply shutter 1 is attached. The operation member 10 has a crank portion 10a at the center thereof. When the main body cover 3 is fitted to the main body 2, the crank portion 10 a comes into contact with the cap retainer 6. The operation member 10 is driven by a panel opening / closing motor 11 shown in FIG. 2 and rotates in a direction as shown by a solid arrow in FIG.

  As shown in FIG. 2, the main body cover 3 has a substantially rectangular parallelepiped shape, and the entire surface of the main body cover 3 to be fitted with the main body 2 is open. Further, as described above, the vent 3a is provided on the front surface of the main body cover 3. The other four surfaces are not provided with openings, and by fixing the main body cover 3 to the main body 2, there is no gap between it and the wall W, so that the main body 2 can be reliably covered and the outside air Even if the air is supplied to the room, dust or the like does not enter the room.

  A cap 5 is attached to the main body cover 3 at the center of the back surface. As shown in the cross-sectional view of FIG. 3, a convex portion 4 a is formed at the center of the back surface of the panel 4 (the surface facing the front surface of the main body cover 3). It is fitted together and fixed together with the cap presser 6 as will be described later using a fixing member 9b.

  Further, an urging member 12 made of a coil spring is provided around the convex portion 4 a, and the urging member 12 is accommodated in the cap 5. The biasing member 12 is incorporated so that the panel 4 is brought into contact with the main body cover 3 in a normal state, and the panel 4 is in a state of covering the main body cover 3.

  As shown in FIG. 2, one end of the cap 5 is composed of a fixed portion 5 a fixed to the main body cover 3 and a movable portion 5 b that hits the back surface of the panel 4 and pushes the panel 4 in the X direction. The fixed portion 5a is provided at the center of one end of the cap 5, and the movable portion 5b is provided on the outer peripheral portion coaxial with the fixed portion 5a. On the other hand, a cap presser 6 is connected to the other end of the cap 5. As described above, the fixing member 9 b is used to connect the cap retainer 6 and the cap 5.

  FIG. 4 is an assembly view showing the main body cover 3 from the back side of the air supply shutter 1 according to the embodiment of the present invention. A filter 7 shown in the exploded perspective view of FIG. Further, a through hole 7a is provided at the center of the filter 7, and the cap 5 and the cap presser 6 pass through the through hole 7a. In FIG. 4, the cap 5 is not visible, and the cap retainer 6 connected to the other end of the cap 5 using a fixing member 9b is shown.

  Further, a main body cover side rib 3 c is formed over substantially the entire circumference of the filter 7. As shown in FIG. 3, the main body cover side rib 3 c presses the sealing material 2 e provided over substantially the entire circumference of the main body 2 when the main body 2 and the main body cover 3 are fitted and fixed. Thereby, the adhesiveness between the main body 2 and the main body cover 3 is enhanced, and dust from the outside can be prevented from entering the room.

  The filter 7 is for preventing dust and the like from entering the room from the outside when the air supply shutter 1 is operated (opened). Therefore, any material can be used as the material of the filter 7 as long as these dusts can be removed. In the embodiment of the present invention, a non-woven fabric having a thickness of about 1 cm is employed with fine eyes in order to reliably prevent dust from entering the room. In addition, by changing the roughness of the eyes of the filter 7 according to the situation where the air supply shutter 1 is used, it is possible to appropriately eliminate the entry of dust or the like.

  Next, the operation of the air supply shutter 1 will be described with reference to FIGS. 5 and 6. In a normal state, that is, in a state where the outside air is not supplied to the room, the air supply shutter 1 is in a state where the panel 4 is in contact with the main body cover 3 as shown in FIG. In this state, since the panel 4 covers the front surface of the main body cover 3, the outside air is not supplied into the room through the vent holes 2a and 3a. Therefore, the intrusion of outside air can be prevented more effectively, and outdoor noise does not leak into the room, and a sound insulation effect can be obtained.

  When the air supply operation is started, as shown in FIG. 5, the panel 4 of the air supply shutter 1 moves in the X direction, and the panel 4 is opened. Here, the start of the air supply operation of the air supply shutter 1, that is, the ON of the panel opening / closing motor 11 may directly command the air supply shutter 1 to start the operation, or the operation of other devices such as a range hood. You may make it interlock | cooperate.

  FIG. 6 is a cross-sectional view showing the air supply shutter 1 in the panel open state shown in FIG. 5 cut along the line BB. As shown in FIG. 6, the cap 5 and the cap retainer 6 connected to the panel 4 are moved in the X direction.

  That is, the movement of the panel 4 moving in the X direction, that is, in the direction away from the main body cover 3 is as follows. First, when the panel opening / closing motor 11 rotates the operating member 10, the crank portion 10a moves in the direction of the arrow (X direction) shown in FIG. 2 as described above, and the cap retainer 6 with which the crank portion 10a contacts is moved in the X direction. Moving. The cap retainer 6 is fixed to the other end of the cap 5, and the panel 4 is fixed to one end of the cap 5. Therefore, the cap holder 6 is moved in the X direction by the crank portion 10a, and at the same time, the panel 4 is moved in the direction away from the main body cover 3 (X direction).

  When the panel 4 moves in the X direction, the panel 4 covering the main body cover 3 is separated from the main body cover 3, so that a space (gap) appears between the main body cover 3 and the panel 4. Since this space (gap) is created, the vent 2a and the vent 3a are opened between the panel 4 and the main body cover 3, so that the outside air is introduced into the room (the solid line in FIG. 6). See arrow).

  The urging member 12 is housed in the cap 5, and the urging member 12 urges the panel 4 in the Y direction as described above. Therefore, in order to move the panel 4 in the X direction, the operation member 10 needs to press the cap retainer 6 with a force larger than the urging force.

  As described above, the filter 7 is formed with a through hole 7 a for allowing the cap 5 and the cap retainer 6 to pass therethrough. Therefore, if no special care is taken, dust or the like may enter the room through the gap between the through hole 7a and the cap 5 when the panel 4 is opened and outside air is introduced into the room. Therefore, in the embodiment of the present invention, the size of the through hole 7a of the filter 7 is approximately the same as the size h (see FIG. 6) of the cap 5, and the size H (H> h) larger than the through hole 7a. By using the cap presser 6 having the above, the gap between the through hole 7a and the cap 5 can be completely closed.

  That is, when the operation member 10 moves the panel 4 in a direction (X direction) to move away from the main body cover 3, the collar 6a of the cap presser 6 moves in the X direction while crushing the filter 7 with the vent 3a. . Therefore, the filter 7 exists between the flange 6a and the vent 3a around the through hole 7a. Moreover, the filter 7 is compressed by the collar 6a and the vent 3a, and the eyes of the filter 7 become fine. Therefore, even if outside air is introduced from the outside into the room, it is possible to reliably prevent the entry of dust or the like through the gap between the through hole 7a and the cap 5.

  Note that if the size of the cap retainer 6 including the collar 6a (dimension H shown in FIG. 6) is excessively large, the amount of air supplied to the room is reduced. Determined by trade-off.

  In addition, when the filter 7 is attached or removed, the collar 6a having a larger area than the through hole 7a must be passed. However, since the filter 7 itself has flexibility, the collar 6a passes through the through hole 7a. It can be penetrated by pushing open the through hole 7a.

  When the panel 4 moves in the Y direction and abuts against the main body cover 3 to close the space (gap), the filter 7 that has been crushed by the collar 6a of the cap retainer 6 is restored to its original state, as shown in FIG. It becomes a state. In addition, although the material of the filter 7 is a non-woven fabric, a sponge or the like that can be compressed and can prevent passage of dust or the like may be used.

  As described above, by providing a filter in the middle of ventilation in and out of the room and providing a cap presser that can reliably close a through hole provided in the filter, dust or the like when supplying outside air into the room, etc. Therefore, it is possible to provide an air supply shutter that can reliably prevent the intrusion of air, and can more effectively prevent the outside air from invading and sound insulation.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. For example, in the above-described embodiment, the description has been given of the natural air supply, that is, the air supply shutter that supplies outdoor air to the room using the negative pressure in the room, but the air supply fan and the fan are provided in the pipe duct D. It is also possible to provide a fan motor that rotationally drives the external air so that the outside air is forcibly introduced (supplied) into the room as the fan rotates.

  Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine the component covering different embodiment suitably.
