Also, in the blowout louver adjusting device described in Patent Document 2, when adjusting the angle of the blowout louver, the resin part is elastically deformed, so there is a risk of breakage of the part. Moreover, when it is going to make the intensity | strength of the components elastically deformed strong, there exists a subject that the operation load of a blowing louver becomes large. Moreover, since sliding of resin parts occurs, there is a problem that when the number of operations increases, the protrusions are lost due to wear, and the angle adjustment of the blowing louver may not be possible.

On the lower surface of the frame body 2, there are a link component holding portion 13 for holding the link component 4 movably in the left-right direction, and a plate spring holding portion 14 for supporting and fixing the link component fixing plate spring 6. ing.
The link component holding unit 13 engages with the engaging

portions

33 and 34 of the link component 4 to hold the link component 4 movably.
The leaf spring holding portion 14 includes a leaf spring support portion (engagement rib) 14A for engaging and supporting the link component fixing plate spring 6 and a leaf spring locking portion (here, a protrusion is provided) for fixing the link component fixing plate spring 6. 23).

As shown in FIG. 4, the blade plate 3 is provided with rotating shafts 15 at the upper and lower ends, and the respective rotating shafts 15 are inserted into the bearing holes 10 A and 10 B of the frame body 2 to freely rotate to the frame body 2. Retained.
A support shaft 17 is provided at the center of the blade plate 3 in the vertical direction. The support plate 17 is inserted into and engaged with the support hole 11 of the support plate 12 so that the blade plate 3 is supported by the support plate 11. 12 is supported to be rotatable.
Furthermore, an engagement shaft 16 that engages with the link component 4 is provided on the back side of the lower end of the blade plate 3, and the engagement shaft 16 is engaged with the link component 4, so that the blade is operated by the operation of the link component 4. The horizontal rotation angle of the plate 3 can be adjusted.

As shown in FIG. 5, the link component 4 includes engaging

portions

33 and 34 that engage with the link component holding portion 13 of the frame body 2, an operation portion 18 that is operated by a user, and two blade plates 3. For this purpose, a blade engaging portion 19 is provided. The blade engaging portion 19 has two protrusion shapes, and is engaged with the engagement shaft 16 by inserting the engagement shaft 16 of the blade plate 3 between the two protrusion shapes. The engagement shaft 16 of the slat 3 moves along an arc-shaped track centering on the rotation shaft 15 of the slat 3, but the slat engagement part 19 engages the engagement shaft 16 only in the left-right direction. Since the structure is movable in the direction, the left and right angle of the blade plate 3 can be adjusted via the blade plate engaging portion 19 by operating the operation unit 18 to the left and right.
The link component 4 has a concavo-convex portion 20 formed with a plurality of concavo-convex portions, and the concavo-convex shape is obtained by pressing and engaging the convex portion (the dowel) 21 of the link component fixing plate spring 6 with the concavo-convex portion 20. Is adjusted and fixed by an arbitrary moving distance in the horizontal direction based on The link parts 4 are arranged on the left and right as mirror parts on the louver, and of the four blades 3, the two blades 3 on the right side from the center are the right link parts 4 and the two on the left side from the center. The blades 3 are respectively engaged with the left link component 4, and the angle of the two left and right can be adjusted independently.

As shown in FIG. 6, at one end of the link component fixing plate spring 6, an elastic portion 22 B for engaging and supporting the plate spring holding portion 14 of the frame 2 is formed, and the other end of the link component fixing plate spring 6 is formed. An engaging portion (notch here) 22A fixed to the leaf spring holding portion 14 of the frame 2 is formed. The elastic portion 22B and the engaging portion 22A of the link component fixing plate spring 6 are originally bent at a constant angle. However, when the link component 4 is mounted on the frame body 2, the mounting pressure and the link component fixing are performed. Due to the action of elastic deformation of the leaf spring 6, the engaging portion 22 A of the link component fixing leaf spring 6 is fixed by the leaf spring locking portion 23 of the leaf spring holding portion 14 formed in the frame body 2.
Further, on the surface facing the link component 4 on the side of the engaging portion 22 A of the link component fixing plate spring 6, a convex portion (a dowel) 21 that fits into the concave and convex portion 20 of the link component 4 is formed.

Next, a mode in which the link component fixing plate spring 6 and the link component 4 are assembled to the frame 2 will be described. FIG. 7 shows a state in which only the link component fixing leaf spring 6 is inserted into the leaf spring holding portion 14 of the frame body 2 (FIG. 7A is a schematic diagram, and FIG. 7B is a structural diagram in accordance with actuality. ). When the link component fixing leaf spring 6 is inserted into the leaf spring holding portion 14 and the elastic portion 22B is inserted into the gap between the engagement ribs 14A of the leaf spring holding portion 14, the elastic portion 22B is inserted while being bent. The right side of the link component fixing plate spring 6 is supported by the engaging rib 14A by friction caused by the repulsive force of the elastic portion 22B. On the other hand, the engaging part 22A side of the link component fixing plate spring 6 on which the convex part 21 is formed is bent at a constant angle with respect to the elastic part 22B, and is therefore close to the lower surface side of the plate spring holding part 14. And is not engaged with the leaf spring locking portion 23 of the leaf spring holding portion 14. For this reason, the link component fixing plate spring 6 is detachable from the plate spring holding portion 14.
FIG. 8 shows a state of the link component fixing plate spring 6 when the link component 4 is further attached to the frame body 2 and inserted into the plate spring holding portion 14 from the state of FIG. When the link component 4 is inserted into the leaf spring holding portion 14, the convex portion 21 of the link component fixing leaf spring 6 is pressed and engaged with the concavo-convex portion 20 of the leaf spring holding portion 14. Due to the mounting pressure of the link component 4, the link component fixing plate spring 6 is elastically deformed and its engaging portion 22 A is engaged with the plate spring locking portion 23 of the plate spring holding portion 14 and fixed.

Next, an example of adjusting the blades when the wind direction is changed by operating the link part 4 to adjust the angle of the blades 3 will be described. Since the blade engaging portion 19 of the link component 4 is provided on the back side of the rotating shaft 15 of the blade plate 3 with respect to the operation portion 18 of the link component 4, if the operation portion 18 is slid to the right side, the blade The plate 3 rotates to the left, and when the operation unit 18 is slid to the left, the blade plate 3 rotates to the right.

FIG. 9 is a perspective view showing the arrangement of the blades 3 when the wind direction of the louver 1 is adjusted to the front of the product. By arranging the

operation portions

18A and 18B of the link part 4 at the center of the entire slide width, all the blades 3 are oriented parallel to the left and right side surfaces of the frame body 2 (direction parallel to the blowing direction of the blower). Thus, the air direction of the blower can be the front of the product.

FIG. 10 is a perspective view showing the arrangement of the blades 3 when the wind direction of the louver 1 is adjusted to the right. By sliding both the

operation portions

18A and 18B of the link component 4 to the left side, the vane plate 3 rotates in the right direction. By arrange | positioning all the blades 3 rightward, the ventilation direction of the wind of an air blower can be made into the right direction.

FIG. 11 is a perspective view showing the arrangement of the blades 3 when the wind direction of the louver 1 is adjusted to the left. By sliding both the

operation portions

18A and 18B of the link component 4 to the right side, the vane plate 3 rotates leftward. By arrange | positioning all the blades 3 leftward, the ventilation direction of the wind of an air blower can be made into the left direction.

FIG. 12 is a perspective view showing the arrangement of the blades 3 when the wind direction of the louver is adjusted to a spot (center concentration). By sliding the right operation unit 18A to the right side and the left operation unit 18B to the left side, the two right blade plates 3 rotate leftward and the two left blade plates 3 rotate rightward. By disposing the left and right blade plates 3 so as to face the central direction of the blower, the air blowing range of the blower can be narrowed, and the air can be concentrated on the front of the blower. By narrowing the air blowing range, it is possible to select and blow a place where it is desired to blow in a space such as the interior of a house where a blower is attached. When it is used for a heater or the like, it is possible to intensively heat a place to be warmed such as a floor surface of a room.

FIG. 13 is a perspective view showing the arrangement of the blades 3 when the wind direction of the louver is adjusted to be wide (diffuse left and right). By sliding the right operation unit 18A to the left side and the left operation unit 18B to the right side, the two right blades 3 rotate to the right and the two left blades 3 rotate to the left. By rotating and arranging the left and right blade plates 3 so as to be separated from each other, it is possible to widen the air blowing range of the blower and blow air over a wide range. By expanding the blower range, it is possible to blow a wide range of space such as the interior of a house to which a blower is attached. When used in a heater or the like, it is possible to uniformly heat and blow a wide area of the room.

Next, a mechanism for rotating the louver 1 in a direction orthogonal to the above-described left-right direction (hereinafter referred to as the up-down direction) will be described. This mechanism requires a louver fixing frame 5 and an upper and lower fixing leaf spring 7 described below. FIG. 14A shows a single unit of the upper and lower fixed plate spring 7, and FIG. 14B shows a state where the upper and lower fixed plate spring 7 is attached to the frame body 2.
The upper and lower fixed leaf springs 7 have engaging protrusions 27 as leaf spring engaging portions for engaging with the frame body 2 and bearing holes 28 for insertion into the rotating shaft 24 of the frame body 2. Further, the upper and lower fixed leaf springs 7 are provided with engaging convex portions (engaging dowels) 25 for engaging the concave and convex portions 9 formed of continuous concave and convex portions provided on the louver fixing frame 5 at the upper end portion, and at the lower end portion. A contact protrusion (contact dowel) 26 is provided to prevent the upper and lower fixing plate springs 7 from floating when the louver 1 is angle-adjusted and being caught on the inner surface of the louver fixing frame 5. The vertical fixing plate spring 7 further includes an arc-shaped bent portion 29 for positioning the frame body 2 at the center position of the louver fixing frame 5.

Next, with respect to the vertical rotation mechanism of the louver 1 using the vertical fixing plate spring 7 and the louver fixing frame 5, a schematic cross-sectional view (a) in FIG. 15 and a partially enlarged view in accordance with the actual structure ( Explanation will be made based on b). The vertical fixing plate spring 7 engages an engagement protrusion 27 that is an engagement portion with the frame body 2 into an engagement hole 24A of the frame body 2 and inserts the rotating shaft 24 of the frame body 2 into the bearing hole 28. Thus, the frame 2 is fixed to both side surfaces. When the rotating shaft 24 of the frame body 2 is inserted into the bearing hole 8 of the louver fixing frame 5 and fixed rotatably, the arcuate bent portion 29 positions the frame body 2 in the left-right direction at the center of the louver fixing frame 5. Is done. Further, the engaging convex portion 25 is fitted into the concave portion of the concave-convex portion 9 inside the side surface of the louver fixing frame 5 to be engaged with each other, whereby the rotation angle of the frame body 2 can be fixed to an arbitrary angle.

Next, an example of adjusting the wind direction of the louver when the angle of the frame body 2 is adjusted by the operation unit 30 at the left and right ends of the support plate 12 and the wind direction in the vertical direction is changed is shown in FIGS. Although the operation unit 30 is integrally formed with the support plate 12, the operation unit 30 is separated from the air path by the partition wall 31 provided in the frame body 2, so that the operation unit can be operated even when warm air is blown from the blower. The temperature rise of 30 can be suppressed and the operation unit 30 can be operated by hand.

FIG. 16 shows the state of the louver 1 when the frame 2 is rotated upward by the operation unit 30. When the frame body 2 rotates upward and faces the upper part, the blowing direction can be set to the upward direction. FIG. 17 shows a state of the louver 1 when the frame body 2 is rotated downward by the operation unit 30. The frame body 2 rotates downward and faces the lower part, so that the air blowing direction can be made downward.

With the structure described above, the louver 1 can adjust the wind direction to the right, left, wide, or spot, and can also be adjusted in the vertical direction. That is, by providing the louver 1, it is possible to obtain a blower capable of selecting a wind direction three-dimensionally in front of the blower.

More specifically, the following effects can be obtained. By dividing the link component 4 into two parts on the left and right, it is possible to blow not only on the left and right but also in a wide range or in a concentrated manner, and the wind direction adjustment function of the louver 1 is improved. Moreover, since the length can be shortened by dividing | segmenting the link component 4 into two, the moldability in the case of shape | molding with resin improves and dimensional accuracy also improves. Moreover, the dimension of the metal mold | die of the link component 4 can be reduced in size. Furthermore, since the number of blades 3 fixed to one link component 4 is reduced, the assemblability is improved.

In addition, the function of adjusting the wind direction of the louver 1 is improved by enabling the louver 1 to be rotated and adjusted in the vertical direction.
Further, by using the

leaf springs

6 and 7 as means for adjusting the angle, the frictional force is reduced and wear due to repeated operations is reduced. Further, the operation load can be arbitrarily adjusted by adjusting the shapes of the

leaf springs

6 and 7. Further, by using the

leaf springs

6 and 7, it is possible to make a structure in which parts are not easily damaged during angle adjustment.

In addition, the louver 1 is supported at both ends by providing the

leaf springs

6 and 7 and the concavo-convex portions 20 and 9 for rotating and adjusting the louver in the left-right direction or a direction orthogonal thereto, so that the louver 1 is supported at both ends. The amount of deformation of the louver is reduced, the louver is stabilized, and the angle adjustment operability is improved.

Further, when the vertical fixing plate spring 7 is inserted into the rotating shaft 24 of the louver 1 and the louver 1 is attached to the louver fixing frame 5, the louver fixing frame whose arcuate bent portion 29 of the vertical fixing plate spring 7 is the opposing surface. The louver 1 can be pushed in the center direction by the elasticity of the arcuate bent portion 29 by being elastically deformed in contact with the side surface of 5. The louver fixing frame 5 and the louver 1 need to be provided with a certain clearance in order to adjust the angle of the louver 1. The position of the louver in the direction of the rotation axis varies depending on the clearance, but by providing the upper and lower fixed leaf springs 7 at both left and right ends, the louver 1 is pushed equally from the left and right through the arc-shaped bent portion 29 toward the center. Therefore, the louver 1 can be rotatably fixed to the center position of the louver fixing frame 5.

Further, when the vertical fixing plate spring 7 is elastically deformed when the angle of the louver 1 is adjusted, even if the end of the louver fixing frame 5 on the side that does not fit into the concavo-convex portion 9 is lifted, the contact convex portion 26 remains on the side surface of the louver fixing frame 5. Because it comes into contact with the surface, it is difficult to get caught. Moreover, the contact area of the contact convex part 26 to the louver fixing frame 5 is small, and the frictional force can be reduced.

The blower provided with the louver of the present invention can be used as a home or business blower such as an air conditioner, a bathroom dryer or a bathroom heater.
