Description

  The present invention relates to a ventilation unit shutter capable of adjusting the wind direction and a ventilation unit to which the ventilation unit shutter is attached.

  Based on the amendment to the Building Standards Law, which was constructed on July 1, 2003, all newly constructed and renovated houses were required to install ventilation equipment, and ventilation units were installed on the walls of the rooms.

  By installing this ventilation unit, there is a problem that the wall and furniture near the air supply opening of the ventilation unit are contaminated by dust etc. mixed in outside air flowing from the ventilation through hole provided on the wall It became. Also, especially during the winter season when cold air flows in, depending on the layout of the room, there was a problem that the cold air hits the residents directly.

  Therefore, in order to solve the above problems, a vent cover that can prevent a desired portion of the air supply port in the ventilating unit has been developed (for example, Patent Document 1).

  This vent cover can be repositioned so that the air volume adjustment plate projects rearward toward the mechanism body and blocks a predetermined part of the air supply opening between the base body opening and the air volume adjustment plate The airflow controller is designed to prevent blowout from the desired direction, prevent soiling of furniture and walls regardless of the location of the ventilation unit, and direct outside air to the resident's body. It is said that touching can be prevented.

  However, the ventilation cover described above has an air volume adjustment plate formed by sandwiching an annular slide substrate with a fixed wind direction controller between three plates, a front plate, a middle plate, and a rear plate, Since the annular slide board can be rotated in the air flow adjustment plate by assembling the inner circumference of the slide board so that the outer peripheral surface of the cylindrical roller fitted into the pin is in contact, it has a very complicated configuration. There are many parts as well.

  Moreover, since the vent cover described above has a very complicated configuration, it is not possible to replace parts such as replacing the wind direction controller with a different width after installation, and it is impossible to change the range for closing the air supply port after installation.

  In addition, this ventilation port cover can only be attached to the corresponding ventilation unit itself, and if you want to add wind direction adjustment function to an existing ventilation unit that does not have wind direction adjustment function, almost all of the ventilation unit will be It had to be replaced and was not versatile.

  Furthermore, although the ventilation direction controller described above is formed so that the wind direction controller can rotate, the wind direction controller is provided between the adjacent turbulence prevention plates because the turbulence prevention plates are provided at the four corners of the wind direction adjustment plate. In other words, only four fixed angles can be set.

  However, although a ventilation unit is installed at the time of construction of a building, inconvenience caused by outside air flowing in from an air supply port may be recognized after moving in.

  When installing a ventilation unit that does not feel necessary at the time of construction or has a wind direction adjustment function in terms of cost, in order to give the wind direction adjustment function after moving in, other than replacing the entire ventilation unit as described above Therefore, a large-scale replacement work is required.

  Moreover, even if the ventilation unit provided with the wind direction adjustment function was installed at the time of construction, it was not possible to change the range for closing the air supply port as necessary.

The lid and the wind direction adjusting member are fixed via an elastic member that expands and contracts in the advancing and retracting direction of the expansion and contraction mechanism.

  In addition, the lid side locking portion and the wind direction adjusting member side locking portion can be engaged by the restoring force of the elastic member that is pressed and elastically deformed by the wind direction adjusting member.

  Further, the movable range of the wind direction adjusting member that is pressed against the wind direction adjusting member when the mechanism body of the ventilation unit is pushed backward from the shortest state of the telescopic mechanism is smaller than the range in which the elastic member contracts. can do.

  In addition, the outer shape of the elastic member can be made larger than the outer shape of the wind direction adjusting member, and the opening edge of the ventilation unit body can press the elastic member in the shortest state of the telescopic mechanism.

  Below, the state which attached the shutter S which concerns on this embodiment to the expansion-contraction mechanism 7 with which the ventilation unit main body H was equipped is demonstrated, referring FIGS. 7-9.

  FIG. 7 shows the longest state of the telescopic mechanism 7 (the state where the distance between the opening of the ventilation unit main body H and the shutter S is the widest). A part of the air supply port 80 generated between the opening of the ventilation unit main body H and the shutter S is blocked by the air direction adjusting plate 42 of the air direction adjusting member 4 attached to the shutter S. Accordingly, it is possible to prevent inflow of outside air from a part of the air supply port 80, that is, a portion where the air direction adjusting plate 42 of the air supply port 80 is located.

  FIG. 10 is an explanatory diagram showing a use state when the ventilation unit of FIG. 7 is attached to the wall 81 of the building, and inflow of outside air to the lower side where the wind direction adjusting plate 42 is located is prevented.

  Further, since the shutter S according to the present embodiment can attach the air direction adjusting member 4 at an appropriate angle as described above, the air direction adjusting plate 42 can be easily positioned at an appropriate position of the air supply port 80 to be closed. In addition, it is possible to change the range of the air supply port 80 to be closed by changing to the wind direction adjusting member 4 including the wind direction adjusting plate 42 having an appropriate width.

  Furthermore, if the telescopic mechanism 7 has a configuration capable of maintaining a stepwise stop state, the distance between the opening of the ventilation unit main body H and the shutter S can be narrowed or widened according to the degree of overhang. The air supply can be adjusted.

  FIG. 8 shows the expansion / contraction mechanism 7 in the shortest state, that is, the closed state in which the shutter S is fitted in the fitting recess 53 of the ventilation unit main body H. In this state, the shutter S closes the opening of the ventilation unit main body H, and no air is supplied.

  Further, the outer shape of the elastic member 2 provided on the shutter S is made larger than the outer shape of the airflow direction adjusting member 4 so that the extension mechanism 7 is in the shortest state and the opening edge portion 68 of the ventilation unit main body H as shown in FIG. If the elastic member 2 is pressed, the play for pushing the elastic member 2 further backward from the shortest state to the release state is formed, and the airtightness in the closed state of the shutter S is improved.

  FIG. 9 shows a released state in which the expansion / contraction mechanism 7 is pushed backward from the shortest state by a play amount. When the pushing force is weakened in this pushed-in state, the telescopic mechanism 7 shown in FIG. 7 returns to the longest state and the shutter S is opened.

  In this release state, depending on the structure of the ventilation unit main body H to which the shutter S is attached, as shown in FIG. 9, the inside of the mechanism main body 6 of the ventilation unit (the support arm 64 in the mechanism shown in FIG. 9) and the wind direction adjusting member 4 ( In the wind direction adjusting member 4 shown in FIG. 9, the wind direction adjusting plate 42) contacts. At this time, since the wind direction adjusting member 4 is fixed to the lid 1 via the elastic member 2 that expands and contracts in the advancing and retracting direction of the expansion and contraction mechanism 7, the wind direction adjusting member 4 is elastic member by the amount pressed by the mechanism body 6. 2 is contracted and moved to the front side (lid side), so that it becomes an appropriate release state and can return to the longest state.

  That is, the movable range of the wind direction adjusting member 4 in which the mechanism main body 6 of the ventilation unit is brought into contact with and pressed against the wind direction adjusting member 4 in the released state in which the telescopic mechanism 7 is pushed backward is the range in which the elastic member 2 contracts. If the shutter S is configured to be smaller, it can be appropriately attached to the ventilation unit main body H that is opened and closed by the so-called push-type telescopic mechanism 7.

  Normally, if a shutter S having a wind direction adjusting function is to be attached to an existing ventilation unit having no wind direction adjusting function, a thin design is required so that the mechanism body 6 and the wind direction adjusting plate 42 do not interfere with each other. According to the shutter S in the present embodiment, an existing ventilation unit that does not have a wind direction adjusting function can be easily changed to a ventilation unit that has a wind direction adjusting function.

  In the shutter S of the present embodiment, the outer shape of the elastic member 2 is larger than the outer shape of the wind direction adjusting member 4, the expansion mechanism 7 is in the shortest state, and the opening edge portion 68 of the ventilation unit main body H is the elastic member 2. However, for example, a member that is elastic on the opening edge 68 side may be provided to push from the shortest state to the released state. .

  In addition, the ventilation unit to which the shutter S according to the present embodiment is attached can block an appropriate part of the air supply port 80, and the air direction adjusting member 4 including the air direction adjusting plate 42 having an appropriate width can be easily provided. It can be changed to a simple one with few parts.

  The present invention is not limited to the configuration of the above-described embodiment, and can be implemented by appropriately changing the shape, dimensions, materials, and the like. For example, the substrate 41 of the wind direction adjusting member 4 is formed into a long and narrow rectangular plate body, and the wind direction adjusting plate 42 is provided in the vicinity of the end portion on one end side, and the engaging portion is engageable with the mounting portion 11 on the other end side. The first fixing portion 39 can be concave and the second fixing portion 45 can be convex and engaged.

  Further, the elastic member 2 is not limited to the shape described above, and is provided in at least a part between the lid body 1 and the substrate 41 of the wind direction adjusting member 4 so that the elastic member 2 is pressed and elastically deformed by the wind direction adjusting member 4. Due to the restoring force, the lid side locking portion 38 and the wind direction adjusting member side locking portion 43 are engaged and fixed, and the mechanism main body 6 of the ventilation unit is in the released state with the expansion and contraction mechanism 7 being released. It is sufficient that the elastic member 2 contracts in a larger range than the movable range in contact with and pressed.
