Description

  The present invention relates to a wind direction adjusting mechanism that is attached to a gas blowing unit such as an air conditioner and that can adjust the direction of the flow of gas blown from the blowing unit.

  Conventionally, a mechanism capable of adjusting the wind direction of air blown out is sometimes attached to a blowout port of an air conditioner or the like.

For example, Japanese Patent Application Laid-Open No. 10-119563 discloses a ventilator that is attached to an air outlet of an air conditioner, has vertical fins and horizontal fins for adjusting the wind direction, and can adjust the wind direction by rotating these fins. Is described. As an example of the wind direction adjusting mechanism, for example, Japanese Patent Application Laid-Open No. 2007-218505 describes a plurality of vertical wind direction plates arranged in a louver shape in the horizontal direction at intervals.
Japanese Patent Laid-Open No. 10-119563 JP 2007-218505 A

  As described in the above-mentioned documents, the conventional wind direction adjusting mechanism generally adjusts the wind direction using a plate member for adjusting the wind direction such as a fin or a wind direction plate. Moreover, in order to adjust the flow of the gas blown out from the outlet in a plurality of directions such as the vertical direction and the horizontal direction, each of the vertical fins and the horizontal fins is used as in a ventilator described in JP-A-10-119563. Generally, a plate member for adjusting the wind direction corresponding to the direction is provided, and these are rotated to adjust the wind direction in the vertical direction and the horizontal direction.

  However, in the conventional wind direction adjusting mechanism, a number of plate members for adjusting the wind direction corresponding to the number of wind directions to be adjusted are necessary. Therefore, in order to adjust the wind direction in a plurality of directions, a plurality of plate members for adjusting the wind direction are required. As a result, the number of plate members for adjusting the wind direction increases, and there is a problem that the structure of the wind direction adjusting mechanism is complicated accordingly.

  In addition, in the conventional wind direction adjusting mechanism, a plate-shaped member for adjusting the wind direction is often attached to the front side of the air outlet, and it is also fixed in terms of design and tends to come in the appearance, pursuing a novel design It was also difficult to do.

  The present invention has been made to solve the above-described problems, and provides a wind direction adjusting mechanism that can simplify the structure and can be innovative in design. With the goal.

  The wind direction adjusting mechanism according to the present invention is movably accommodated in a casing having a gas outlet, and forms a gas passage between the casing and the inner surface of the casing, and can adjust the direction of the gas blown from the outlet. A wind direction adjusting member and a drive unit attached to the casing and capable of driving the wind direction adjusting member to move within the casing. And the wind direction of the gas which blows off from a blower outlet is adjusted by moving a wind direction adjustment member within a casing by a drive part, and changing the cross-sectional shape of a gas passage.

  The said wind direction adjustment member is typically comprised by the solid which has a volume of the grade which can adjust a wind direction by moving within a casing. For example, from the viewpoint of reducing the weight and accommodating various elements inside, it is conceivable that the wind direction adjusting member has a hollow shape. For example, the shape of the wind direction adjusting member is a shape having an outer shell portion that defines a space inside the wind direction adjusting member, and an inner shell portion that is disposed inside the outer shell portion and is movable with the outer shell portion. It is also possible to do.

  The drive unit is, for example, a first rotary shaft that is rotatably attached to the casing so as to penetrate the wind direction adjusting member, and a rotary shaft that is rotatably attached to the casing so as to penetrate the wind direction adjusting member. A second rotating shaft extending in a direction intersecting (typically orthogonal), a first operating member capable of rotating the first rotating shaft, a second operating member capable of rotating the second rotating shaft, A first power transmission unit that is directly or indirectly provided on the wind direction adjusting member, transmits the power from the first rotating shaft, and can convert the rotational motion of the first rotating shaft into a translational motion in the first direction; And a second power transmission unit that is directly or indirectly provided on the member, transmits power from the second rotating shaft, and can convert the rotational motion of the second rotating shaft into translational motion in the second direction. May be.

  The wind direction adjusting member can be moved in the first direction by rotating the first rotating shaft with the first operating member, and the wind direction adjusting member can be moved by rotating the second rotating shaft with the second operating member. It can be moved in the second direction.

  A gap may be provided between the outer shell portion and the inner shell portion. In this case, the wind direction adjusting mechanism is installed in the gap so as to be slidable and inserted through the first rotating shaft, and is installed in the gap so as to be slidable and inserted through the second rotating shaft. A second slide member may be further provided.

  In the wind direction adjusting mechanism according to the present invention, the wind direction of the gas blown out from the outlet is adjusted by moving the air direction adjusting member in the casing and changing the cross-sectional shape of the gas passage. Even when it is desired to adjust the flow in a plurality of directions, it is possible to cope with a smaller number of wind direction adjusting members than the number of directions to be adjusted. Thereby, the number of wind direction adjusting members can be reduced, and as a result, the structure of the wind direction adjusting mechanism can be simplified. Further, since the wind direction adjusting member can be accommodated in the casing, the design can be as innovative as ever.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5A and 5B. FIG. 1 is a perspective view of a wind direction adjusting mechanism 1 according to one embodiment of the present invention.

  As shown in FIG. 1, the wind direction adjusting mechanism 1 of the present embodiment includes a casing 2 having a gas outlet 2 a, a wind direction adjusting member 3, and a drive unit for the wind direction adjusting member 3.

  The casing 2 has a hollow shape and can be produced using, for example, a resin. The casing 2 has a gas flow path through which a gas such as air flows. In the example of FIG. 1, an air outlet 2 a is provided on one end side of the casing 2, and a gas inlet port through which gas can be sent into the casing 2 is provided on the other end side.

  The wind direction adjusting member 3 is made of, for example, resin, and is housed in the casing 2 so as to be movable. A gas passage is formed between the wind direction adjusting member 3 and the casing 2. In the example of FIG. 1, a gas passage is formed between the outer surface of the wind direction adjusting member 3 and the inner surface of the casing 2.

  In FIG. 3, the fragmentary sectional view of the wind direction adjustment mechanism 1 is shown. As shown in FIG. 3, the wind direction adjusting member 3 is typically configured as a solid having a predetermined volume. In more detail, it is comprised by the solid which has a volume of the grade which can adjust a wind direction by moving within the casing 2. FIG. In addition, from the viewpoint of weight reduction and effective use of the internal space, the wind direction adjusting member 3 is preferably hollow, but it is also conceivable to be solid. As the specific shape of the wind direction adjusting member 3, any three-dimensional shape can be adopted. For example, a rounded three-dimensional shape such as a spherical shape, a spindle shape, an oval shape, a cylindrical shape, a prismatic shape, a conical shape, a pyramid It is conceivable to have an elongated shape such as a shape.

  In the example of FIG. 3, the wind direction adjusting member 3 has a hollow substantially spherical shape. As shown in FIG. 3, the wind direction adjusting member 3 is disposed inside the outer shell portion (outer member: outer frame) 3a that defines a space therein, and is movable inside the outer shell portion 3a. And a certain inner shell (inner member: inner frame) 3b. In addition, you may connect the outer shell part 3a and the inner shell part 3b via some connection member.

  The drive unit is provided in the casing 2, drives and moves the wind direction adjusting member 3 in the casing 2, and a cross-sectional shape of the gas passage around the wind direction adjusting member 3 (the axial direction of the casing 2, which is the direction in which the gas flows) The shape of the gas passage when the wind direction adjusting member 3 is cut together with the casing 2 on a plane orthogonal to each other can be changed. Thus, by changing the cross-sectional shape of the gas passage, the flow rate of the gas passing through the gas passage can be changed in the direction along the outer periphery of the wind direction adjusting member 3.

  For example, when the wind direction adjusting member 3 is located at the center position indicated by the solid line in FIG. 4 (assuming that the air direction adjusting member 3 is also in the center position of the casing 2 in the direction perpendicular to the paper surface), The flow rate of the gas passing through the gas passage 11 is almost equal, and the gas is blown out almost straight to the left in FIG. By moving the wind direction adjusting member 3 from this central position to the position of the dotted line in FIG. 4, the flow rate of the gas passing through the gas passage 11 located on the upper side of FIG. 4 is changed to the gas passage located on the lower side of FIG. 11 and the flow direction of the gas blown out from the outlet 2a can be changed downward in FIG. Thus, the wind direction of the gas blown out from the blower outlet 2a can be adjusted.

  In the wind direction adjusting mechanism 1 of the present embodiment, the wind direction of the gas blown out from the outlet 2a is changed by moving the air direction adjusting member 3 in the casing 2 and changing the cross-sectional shape of the gas passage 11 as described above. Since the adjustment is made, the number of wind direction adjusting members 3 can be reduced as compared with the conventional one. Accordingly, the structure of the wind direction adjusting mechanism 1 can be simplified.

  Further, for example, as shown in FIG. 1, since the wind direction adjusting member 3 can be accommodated in the casing 2, it is not necessary to install fins or the like on the front side of the air outlet 2a, and the design is simple and conventional. It will be something novel.

  As shown in FIG. 4, the inner diameter of the casing 2 is largest at the central portion in the axial direction of the casing 2 (the left-right direction in FIG. 4), which is the gas flowing direction, and the inner diameter of the outlet 2 a is the axis of the casing 2. It is smaller than the inner diameter of the central portion in the direction. Thereby, as shown by the arrow in FIG. 4, when the wind direction adjusting member 3 is located at the center position of the casing 2, the gas that passes through the upper and lower gas passages 11 and is blown out from the outlet 2 a approaches each other. Can lead to. That is, the casing 2 has a shape constricted at the air outlet 2a, and the gas that has passed through the upper and lower gas passages 11 is blown obliquely forward from the air outlet 2a, and these are merged in front of the air outlet 2a. be able to. As seen from the left side of FIG. 4, the gas passage 11 has an annular shape, so that the gas that has passed around the wind direction adjusting member 3 joins in front of the air outlet 2 a. As a result, it is possible to avoid the gas blown out from the air outlet 2a from directly hitting a person, and a mild wind can be supplied from the air outlet 2a into the room.

  Further, as shown in FIG. 4, the inner surface of the casing 2 may be shaped along the outer surface of the wind direction adjusting member 3 so that the outer surface of the wind direction adjusting member 3 can come into contact. For example, when the outer surface of the wind direction adjusting member 3 is convex, the inner surface of the casing 2 facing the wind direction adjusting member 3 may be concave. Thereby, as shown by a dotted line in FIG. 4, the contact area between the outer surface of the wind direction adjusting member 3 and the inner surface of the casing 2 can be increased, and a part of the gas passages 11 can be easily blocked. it can.

  Typically, the drive unit converts a rotational motion into a translational motion and transmits the translational motion to the wind direction adjusting member 3, and moves the wind direction adjusting member 3 in a desired direction within the casing 2. However, any other driving method can be adopted as long as the wind direction adjusting member 3 can be moved in a desired direction within the casing 2.

  In the example of FIGS. 1 to 3, the drive unit is attached to the casing 2 so as to penetrate the first rotation shaft 7 a rotatably attached to the casing 2 so as to penetrate the wind direction adjustment member 3 and the wind direction adjustment member 3. A second rotating shaft 7b that is rotatably attached and extends in a direction orthogonal to or intersecting the first rotating shaft 7a, a first operating member 4a that can rotate the first rotating shaft 7a, and a second rotating shaft 7b. And a second operating member 4b that can be rotated.

  As shown in FIG. 2, the first rotating shaft 7a is connected to the first operating member 4a via a plurality of gears 6a, 6b, 6c, and the first rotating member 7a is rotated by rotating the first operating member 4a. The shaft 7a can be rotated. In the example of FIG. 2, the inner teeth 10 are formed on the inner peripheral portion of the first operating member 4a, the gear 6a is provided on the outer side so as to mesh with the inner teeth 10, and the gear in the middle so as to mesh with the gear 6a. 6b is provided, a gear 6c is provided on the inner side so as to mesh with the gear 6b, and the first rotary shaft 7a can be rotated together with the gear 6c. At this time, by installing a predetermined number of gears between the first rotating shaft 7a and the first operating member 4a, the first rotating shaft 7a and the first operating member 4a can be rotated in the same direction. . Since the shape of the second rotating shaft 7b and the second operating member 4b and the connection structure between the second rotating shaft 7b and the second operating member 4b are the same as those of the first rotating shaft 7a and the first operating member 4a, Description is omitted.

  As shown in FIGS. 1 to 3, the first operating member 4 a and the second operating member 4 b are arranged on the outer surface of the casing 2 with a space therebetween. More specifically, the first operating member 4a and the second operating member 4b are arranged at a position shifted by approximately 90 degrees in the outer peripheral direction of the casing 2. In addition, in the example of FIGS. 1-3, although the shape of the 1st operation member 4a and the 2nd operation member 4b is disk shape, it can be set as arbitrary shapes other than this. The first operating member 4a and the second operating member 4b are fixed to the casing 2 by the locking members 5a and 5b.

  As shown in FIG. 3, the 1st rotating shaft 7a has the 1st spline part 8a in the center part of the length direction. On the other hand, the wind direction adjusting member 3 is provided with a first power transmission wall (first power transmission portion) 9a at a position facing the first spline portion 8a. The first power transmission wall 9a is typically provided in the wind direction adjusting member 3, but may be provided in either the outer shell portion 3a or the inner shell portion 3b. Moreover, although the 1st power transmission wall 9a may be directly installed in the wind direction adjustment member 3, you may make it attach to the wind direction adjustment member 3 indirectly through a certain member. Further, the number of first power transmission walls 9a may be one or more, but may be plural. By using a plurality, the first spline portion 8a can be stably supported by the first power transmission wall 9a.

  A plurality of teeth that mesh with the first spline portion 8a are provided on the surface of the first power transmission wall 9a (the surface facing the first spline portion 8a). By engaging a plurality of teeth on the surface of the first power transmission wall 9a and the first spline portion 8a, the rotational movement of the first rotating shaft 7a is transmitted through the first spline portion 8a. It can be transmitted to the wall 9a.

  Further, as shown in FIG. 3, the respective teeth on the surface of the first power transmission wall 9a are arranged in the vertical direction (first direction) in FIG. Thereby, the rotational motion of the 1st rotating shaft 7a can be converted into the translational motion of the up-down direction of FIG. As a result, by rotating the first rotating shaft 7a by the first operating member 4a, the wind direction adjusting member 3 can be translated in the vertical direction, and the wind direction adjusting member 3 is moved in the vertical direction in the casing 2. be able to.

  Similarly to the case of the first rotation shaft 7a, the second rotation shaft 7b also has a second spline portion 8b at the center in the length direction. The wind direction adjusting member 3 is provided with a second power transmission wall (second power transmission portion) 9b at a position facing the second spline portion 8b. The second power transmission wall 9b is also typically provided in the wind direction adjusting member 3, but may be provided in either the outer shell portion 3a or the inner shell portion 3b. Also, in the case of the second power transmission wall 9b, it may be directly installed on the wind direction adjusting member 3, but it may be indirectly attached to the wind direction adjusting member 3 through some member. Further, in the case of the second power transmission wall 9b, the number thereof may be singular or plural, or plural. However, by using a plurality, the second spline portion 8b can be stably supported by the second power transmission wall 9b.

  A plurality of teeth that mesh with the second spline portion 8b are also provided on the surface of the second power transmission wall 9b (the surface facing the second spline portion 8b). Thereby, similarly to the case of the first power transmission wall 9a, the rotational motion of the second rotating shaft 7b can be transmitted to the second power transmission wall 9b via the second spline portion 8b.

  As shown in FIG. 3, each tooth portion on the surface of the second power transmission wall 9a is provided so as to be aligned in the lateral direction (second direction) in FIG. Thereby, the rotational motion of the 2nd rotating shaft 7b can be converted into the translational motion of the horizontal direction of FIG. As a result, by rotating the second rotating shaft 7b by the second operating member 4b, the wind direction adjusting member 3 can be translated in the lateral direction, and the wind direction adjusting member 3 is moved in the lateral direction in the casing 2. be able to.

  As described above, the wind direction adjusting member 3 can be translated in the casing 2 by rotating the first operating member 4a and the second operating member 4b. However, as shown by the dotted line in FIG. If the wind direction adjusting member 3 can be moved further to the casing 2 side (the lower side in FIG. 4) when 3 contacts the inner surface of the casing 2, any element of the wind direction adjusting mechanism 1 is damaged. Considered dangerous. Therefore, in the present embodiment, after the airflow direction adjusting member 3 comes into contact with the inner surface of the casing 2 by adopting a ratchet mechanism or the like, the airflow direction adjusting member 3 is not moved further to the casing 2 side. The first operation member 4a and the second operation member 4b are idled.

  In the example of FIG. 3, a gap is provided between the outer shell portion 3 a and the inner shell portion 3 b of the wind direction adjusting member 3. A pair of plate-like slide members (second slide members) 13 are installed in the gap so as to be slidable with respect to the wind direction adjusting member 3 at intervals. The second rotary shaft 7b is inserted through the set of slide members 13, and the slide member 13 and the second rotary shaft 7b are integrated. Similarly, a pair of plate-like slide members (first slide members) through which the first rotation shaft 7a is inserted also slides in the gap between the outer shell portion 3a and the inner shell portion 3b of the wind direction adjusting member 3. Install in a movable manner. In the example of FIG. 3, the annular gap between the outer shell portion 3 a and the inner shell portion 3 b of the wind direction adjusting member 3 functions as a guide portion for the slide member.

  In the outer shell portion 3a and the inner shell portion 3b of the wind direction adjusting member 3, openings (notches) 12a and 12b are formed in portions located above and below each slide member, respectively. Thereby, the wind direction adjusting member 3 can be translated with respect to each rotation axis by a desired distance. Moreover, the length of each opening part 12a, 12b in the moving direction of the wind direction adjusting member 3 is made shorter than the length in the said moving direction of each slide member arrange | positioned above each opening part 12a, 12b. Thereby, it can suppress that a slide member slips out from each opening part 12a, 12b after the movement of the wind direction adjustment member 3. FIG.

  Next, the operation of the wind direction adjusting mechanism 1 of the present embodiment having the above structure will be described with reference to FIGS. 5A and 5B show a case where the second operation member 4b is rotated to move the wind direction adjusting member 3, but the first operation member 4a is rotated to operate the wind direction adjusting member. This is basically the same when moving 3. However, when the first operating member 4a is rotated, the rotating direction of the first operating member 4a and the moving direction of the wind direction adjusting member 3 are the same direction.

As shown in FIG. 5 (a), the second operation member 4b is moved from the left to the right in FIG. 5 (a) from the state in which the wind direction adjusting member 3 is located at the center position inside the casing 2 (second rotating shaft 7b). Rotate in the clockwise direction). Thereby, the 2nd rotating shaft 7b also rotates in the reverse direction to the 2nd operation member 4b.

  At this time, since the second spline portion 8b of the second rotating shaft 7b meshes with the teeth of the second power transmission wall 9b, the rotational motion of the second rotating shaft 7b is transmitted to the second power transmission wall 9b. It is converted into translational motion, and the wind direction adjusting member 3 translates leftward as shown in FIG. The second rotating shaft 7b moves in openings 12a and 12b provided in the outer shell portion 3a and the inner shell portion 3b of the wind direction adjusting member 3, respectively, and each slide member 13 is located outside the wind direction adjusting member 3. Guided by the inner surface of the shell portion 3a and the outer surface of the inner shell portion 3b, it slides within the gap between the outer shell portion 3a and the inner shell portion 3b.

  As shown in FIG. 5B, the cross-sectional shape of the gas passage 11 around the wind direction adjusting member 3 can be changed by moving the wind direction adjusting member 3 to the left in the casing 2, thereby the casing. The wind direction of the gas blown out from the two outlets 2a can be adjusted. When the first operating member 4a is rotated, the wind direction adjusting member 3 can be moved in the vertical direction of FIGS. 5 (a) and 5 (b).

  The wind direction adjusting mechanism described above is typically applicable to an air conditioner outlet. In particular, it is useful for the air outlet of an air conditioner mounted on a vehicle. However, the present invention can be applied to a gas outlet of any other apparatus.

  Although the embodiment of the present invention has been described above, the above-described embodiment can be variously modified. For example, a pinion (small gear) can be used in place of the spline portion provided on each rotating shaft described above, and a rack (plate-shaped gear) combined with the pinion is used in place of the power transmission wall. Is also possible. Further, the shape of the casing is not limited to that described above, and can be any shape.

  The scope of the present invention is not limited to the above-described embodiment. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
