Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air flow direction adjusting device at an air outlet of an air conditioner or a ventilation system, and more specifically, it eliminates ventilation resistance at the air outlet and has excellent operability.
The present invention relates to a wind direction adjusting device with improved air blowing efficiency, and further to a wind direction adjusting device that can obtain various air blowing modes.

[0002]

2. Description of the Related Art In a conventional general wind direction adjusting device, a plurality of wind direction adjusting blades whose centers are axially supported in a case are connected to a connecting rod, and the connecting rod is operated to operate the wind direction adjusting blades. The wind direction is adjusted by rotating the whole body to the left and right or up and down at the same time around the shaft support. However,
In the wind direction adjusting device having such a configuration, when the large number of blades are in a rotating state, the wind that travels straight in the case changes its direction while being repeatedly reflected by the blade surfaces, resulting in an air volume loss between them. Alternatively, there is a problem that noise is generated.

In order to solve these problems, for example, as disclosed in Japanese Utility Model Laid-Open No. 51-2849, a large number of wind direction adjusting blades made of leaf spring material are pressed from their longitudinal ends toward the center. Then, the blades are arranged in parallel in the case in a state of being deformed in an arc shape, and one end and the central portion of each blade are fixed in position, and the connecting rods connected to the other ends of the blades are operated left and right. There is one in which the wind direction is changed to the left or right while the arc surface of the blade is deformed in the opposite direction. Therefore, after changing the wind direction, each blade maintains an arc shape, and the wind that travels straight in the case flows along the arc surface of the blade and is blown out from the air outlet, so there is little ventilation resistance and no noise is generated. In addition, there is less air flow loss.

[0004]

However, in the wind direction adjusting device disclosed in the above publication, pressure is applied to the wind direction adjusting blades made of leaf spring material from both ends in the longitudinal direction toward the center to forcibly make a circle. Since it is mounted in the case in a curved shape in an arc, and the connecting rod is only movable in the same part to the left and right, the front and rear positions of the wind direction adjusting blade are restricted, and the wind direction is adjusted. When elastically deforming the adjustment blades in the left-right direction, the mounting part of the case is likely to receive a strong elastic force by the wind direction adjustment blades, the operability of the connecting rod is poor, and the bending direction of the wind direction adjustment blades is changed. , The wind direction adjusting blades are always curved and deformed into a wavy shape, so
It is impossible to smoothly form the wind direction adjusting blade into a desired curved shape.

Therefore, in the case of the wind direction adjusting device disclosed in the above publication, if the operability is neglected, the left and right final deformations are possible, but the wind direction cannot be obtained in the middle of the deformation, and the deformation is forced during the deformation. Even if the operation is stopped, there is no guarantee that the wind direction adjusting blades will be uniformly deformed, and not only the desired wind direction cannot be obtained, but also the ventilation resistance increases and the air volume loss also increases. Furthermore, the air flow obtained is always a parallel flow, and various blowout forms such as diffusive flow and concentrated flow cannot be obtained.

The object of the present invention is to solve the above problems, to change the direction and shape of the blowout flow, to eliminate the airflow resistance of the air blowout port, to obtain smooth operability, and to improve the air blowing efficiency. It is to provide an improved wind direction adjusting device.

[0007]

In order to achieve the above object, the present invention is an air flow direction adjusting device installed in an air blowing portion of an air conditioner or the like and adjusting the direction of the air flow blown from the air blowing portion. A case having an air outlet, a plurality of parallel wind direction adjusting blades made of a flexible material rotatably supported at a substantially central portion of the case, and formed inside the case. A pair of guide portions that guide the upstream and downstream end edges of the adjustment blades in the upstream and downstream directions respectively, and a reverse movement mechanism that alternately moves in a direction intersecting the installation direction of the wind direction adjustment blades, The wind direction adjusting device is characterized by comprising interlocking means for interlocking the upstream side and the downstream side of the blade.

In addition to the above-mentioned means, the present invention is provided with a second reverse moving mechanism in which the wind direction adjusting blades are divided into two groups, and the front portion of each group is staggeredly moved in a direction intersecting the installation direction. Sometimes.

[0009]

According to the reverse movement mechanism, that is, according to the preferred embodiment, when the motor is started, the link operating gear having the eccentric projection is rotated via the drive gear, and the eccentric ring member having the eccentric projection is also rotated via the rotating shaft. To do. By the rotation of the operating gear and the eccentric ring member, the protrusion cooperates with the substantially L-shaped upper and lower link members to alternately reciprocate the upper and lower link members in the case. The protrusions are arranged with a phase difference of 180 °, and the upper and lower link members reciprocate in opposite directions even if the operating gear and the eccentric ring member rotate in the same direction.

Now, when a large number of vertical blades 8 are in a parallel state and the motor is started in this state to move the upper link member and the lower link member in opposite directions, the respective link members are placed on the upstream and downstream sides of the air. The wind direction adjusting blades connected to the end portions are gradually curved to the left at the rear part with the central shaft part as a fulcrum, and at the same time, gradually curved to the right part at the front part of the central shaft part 8a. , S-shaped curved state. When the motor is further driven, the upper and lower link members 10 and 12 are moved in opposite directions, and the wind direction adjusting vanes are deformed into an inverted S shape after being returned to parallel.

When the wind direction adjusting blades are deformed as described above by the reciprocating movement of the upper and lower link members, the sliding shafts protruding vertically from the front and rear ends of the blades are guided by the long holes formed in the upper and lower sides of the case to move back and forth. It moves so that no excessive force is applied to the front and back of the blade.

By thus reciprocally moving the upper and lower link members in opposite directions, the wind direction adjusting blades are smoothly deformed into an S-shape or an inverted S-shape, and the wind direction blown out from the air outlet can be easily changed to the left and right. Simultaneously with the change, the linear flow sent from the blower unit changes the wind direction along the curved surface of the blade without being interfered in the middle, so that the loss of the air volume is reduced, and the movement of the upper and lower link members can be changed at any position. When stopped with, the amount of deformation of the blades can be arbitrarily set, and the wind direction can be set to any direction within the deformation limit of the wind direction adjusting blades.

In the present invention, the wind direction adjusting device is the second.
When the reverse moving mechanism is provided, the first reverse moving mechanism is stopped and the second reverse moving mechanism is operated, and the front portion of the wind direction adjusting blade divided into two groups is directed toward the center. At the same time, the other groups also deform toward the center, and a concentrated flow is obtained. Further, when the second reverse movement mechanism is operated in the opposite direction to the above, the wind direction adjusting blade is deformed in the direction in which the two groups are separated from each other, and a diffused flow is obtained.

In these drawings, reference numeral 1 denotes a ventilator, and a case 2 has a side surface provided with a motor unit 3 in which an output shaft is vertically arranged via a bracket. Gear 4 fixed to the output shaft of the motor unit 3
The a is meshed with the operating gear 4b fixed to the upper end of the rotary shaft 5 arranged vertically on the side of the case 2. The rotating shaft 5 is rotatably supported by a pair of upper and lower shaft support brackets 2d protruding from the side surface of the case 2. A first link actuating protrusion 6a projects at an eccentric position on the upper surface of the actuating gear 4b. An eccentric ring member 7 is tightly fitted and fixed to the lower end of the rotating shaft 5, and the eccentric ring member 7 projects downward toward the target eccentric position with the first link operating projection 6a interposed therebetween. The second link operating protrusion 6b is provided.

A large number of vertical blades 8 are arranged in parallel on the upper and lower inner wall surfaces of the case 2 at the center of the inside of the case 2 through a center rotation shaft 8a. A large number of horizontal blades 9 are arranged in parallel on the wall surface via a left / right rotation shaft 9a.

The vertical blade 8 is made of a flexible elastic plate material formed of a synthetic resin material or a metal material, and has the shaft portions 8a at the upper and lower ends of its central portion as described above, and further the front and rear ends thereof. Slide shafts 8 are attached to the upper and lower ends of the
b and 8c. One of the horizontal blades 9 has the same structure as the conventional one, which is also formed of a synthetic resin material or a metal material. Shaft 9a is case 2
Is rotatably supported between the side walls.

The case 2 is in the form of a rectangular tube having front and rear openings, and the vertical shaft portions 8a, 8a of the vertical blade 8 are rotated at the central portions of the upper and lower inner wall surfaces corresponding to the installation positions of the vertical blade 8. Shaft holes 2a, 2a that are movably fitted and supported are formed, and sliding shafts 8b, which protrude from the front and rear ends of the vertical blades 8,
8c has long holes 2b, 2c which are long in the front and rear, respectively, in which the sliding shafts 8b, 8c are inserted.
Are formed. Further, link member insertion holes 11 are formed in the left and right side wall portions of the case 2 that intersect with the extension lines connecting the rear upper edges of the large number of vertical blades 8. The insertion holes 11 have both end portions of the upper link member 10 described later. Can be inserted and removed freely. Further, link member insertion holes 13 are also formed in the left and right side wall portions of the case 2 that intersect with the extension lines connecting the front lower edges of the many vertical blades 8, and the lower link members 12 to be described later are formed in the insertion holes 13. Both ends of the are inserted so that they can move back and forth.

The upper and lower link members 10 and 12 have the same shape, one end of an elongated plate member is bent at a right angle to form a substantially L-shape, and the bent end pieces 10a and 12a have one surface. Long grooves 10c and 12c are formed to engage the first and second link operating protrusions 6a and 6b, respectively. A first link operating protrusion 6a protruding from the operating gear 4b and a second link operating protrusion 6b protruding from the eccentric ring member 7 are engaged with the long grooves 10c and 12c, respectively. Further, a pair of blade supporting members is provided on the side where the long grooves 10c and 12c of the long portions 10b and 12b of the upper and lower link members 10 and 12 are formed with an interval equal to the installation interval of the vertical blades 8. A plurality of sets of 10d and 12d are projected, and the lower front end edge and the upper rear end edge of each blade 8 are sandwiched by the support members 10d and 12d.

According to the first embodiment having such a structure,
When the motor unit 3 of the ventilator 1 is started, the operating gear 4b is rotated via the gear 4a, and at the same time the rotating shaft 5
The eccentric ring member 7 also rotates via. Due to the rotation of the operating gear 4b and the eccentric ring member 7, the first and second link operating protrusions 6a, 6b cause the long grooves 10c of the upper and lower link members 10, 12 to move.
Crank rotation while sliding in 12c causes the upper and lower link members 10, 12 to reciprocate left and right. Since the first and second link actuating protrusions 6a and 6b are arranged with a phase difference of 180 °, the upper and lower link members 10 and 12 do not move from each other even if the actuating gear 4b and the eccentric ring member 7 rotate in the same direction. Reciprocates in the opposite direction. The upper and lower link members 10 and 12,
The drive mechanism constitutes the reverse movement mechanism of the present invention.

FIG. 2 shows the positional relationship between the first and second link operating protrusions 6a and 6b when a large number of vertical blades 8 are in a parallel state. As shown in FIG.
6b is on a straight line parallel to the vertical blade 8. Now
When the motor unit 3 is started in this state and the upper link member 10 is operated to the left side of the drawing and the lower link member 12 is operated to the right side of the drawing, the vertical blades 8 are moved to the upper and lower link members 1.
With the blade support members 0d and 12d of 0 and 12, the central shaft portion 8a is used as a fulcrum to be gradually curved leftward at the rear portion, and at the same time, the front portion of the central shaft portion 8a is gradually curved rightward. When the second link actuation projections 6a, 6b come on a straight line connecting the central shaft portions 8a of the vertical blades 8, the S-shaped maximum bending state is obtained as shown in FIG.

When the motor unit 3 is further driven, the vertical blade 8 is returned to its original shape and the upper and lower link members 1 are
When 0 and 12 move in the right and left directions, respectively, and when the state shown in FIG. 2 is exceeded, the vertical blade 8 is deformed into an S-shape reverse to the above, and the maximum curved state shown in FIG. 5 is obtained.

When the vertical blades 8 are deformed by the reciprocating motion of the upper and lower link members 10 and 12, the sliding shafts 8b and 8c protruding vertically from the front and rear ends of the vertical blades 8 are the long holes 2b and 2 of the case 2.
Since it is guided by c and moves back and forth, the vertical blades 8 are smoothly deformed without any unreasonable force.

In the above embodiment, the motor unit 3
Although the upper and lower link members 10 and 12 are operated by driving the vertical blades 8, the vertical blades 8 can be smoothly operated by the manual operation using a dial or the like instead of the motor unit 3 for the reason described above. It can be deformed.

By vertically reciprocating the upper and lower link members 10 and 12 in this manner, the vertical blade 8 is smoothly moved to the S direction.
Since it can be deformed into a letter shape or an inverted S shape, not only the direction of the air blown from the ventilator 1 can be easily changed to the left or right, but the straight flow sent from the blower unit (not shown) is vertical without any interference in the middle. Since the wind direction is changed along the curved surface of the blade 8, the loss of the air volume is reduced, and when the movement of the upper and lower link members 10 and 12 is stopped at an arbitrary position, the above-mentioned deformation of the vertical blade 8 also stops on the way, so The wind direction can be set to any direction within the deformation limit of the vertical blade 8.

7 to 10 show a ventilator 1'which is a second embodiment of the present invention. In this example, the above-mentioned mechanism of the ventilator 1 of the first embodiment is used and a predetermined vertical blade 8'is used. A new blowing mode changing mechanism 30 is added, in which only the front end portion is deformed to the left and right to efficiently obtain a concentrated flow and a diffused flow.

FIG. 7 is an internal side view of the second embodiment device, FIG. 8 is an internal front view of the device, and FIGS. 9 and 10 are internal top views of the device. In these figures, the parts denoted by the same reference numerals as those of the first embodiment shown in FIGS. 1 to 7 indicate substantially the same parts, and therefore, in the following description, the first embodiment will be described. The detailed description of the same parts as those of will be omitted, and new constituent parts will be described in detail.

Ventilator 1'according to this second embodiment
Is different from the ventilator 1 of the first embodiment described above in that the case 2 ′ has a box-shaped frame portion 20 supporting and accommodating the changing mechanism 30 downward from the front end of the lower wall of the case 2 in the first embodiment. The point is that they are integrally extended, and that a change mechanism 30 for changing the form of the blowout flow from parallel flow to concentrated flow or diffusion flow is provided. It has a changed structure.

The box-shaped frame portion 20 is shown in FIGS.
As shown in FIG. 2, the case 2'has a box-like shape with a lower wall serving as a top plate and an opening at the rear, and a vertical sliding shaft 8c 'in front of a vertical blade 8'to be described later formed on the upper and lower walls thereof. The insertion hole 2c 'through which the through hole is inserted has a shape in which the front end of the elongated hole 2c in the first embodiment is communicated with the center of the arcuate hole.
In addition, a front portion inside the box-shaped frame portion 20 (see FIG.
In the right part of the case), a support member 21 for horizontally and rotatably supporting an operation shaft portion 31 described later is provided downward from the lower surface of the case lower wall. Further, on the inner rear side of the box-shaped frame portion 20, upper and lower rack bodies 3 to be described later are provided.
A pair of front and rear guide plate members 22 and 23 for slidingly guiding the guide plates 2 and 33 in the horizontal direction are vertically provided downward from the lower surface of the lower wall, and the shaft portion is provided at the center of the guide plate members 22 and 23. Shaft support holes 24 and 25 are formed to rotatably support the tip of 31.

The blowout form changing mechanism 30 has an operating shaft portion 31 having an operating knob 34 at one end and a rack gear 35 at the other end, and upper and lower rack bodies 32, 33 which mesh with the upper and lower sides of the rack gear 35. Consists of. According to the illustrated embodiment, the upper rack body 32 is made of a substantially F-shaped plate material having the front surface of the lower surface as the rack surface as shown in FIGS. 8 and 9, and the lower rack body 33 has a part of the upper surface as the rack surface. It is made of a substantially F-shaped plate material. Then, the main body 3 of the upper and lower rack bodies 32, 33
Branch pieces 32b, 33b extending at a right angle from 2a, 33a
Long holes 32c and 33c that are long in the length direction are formed at the tip of the.

The overall shape of the vertical blade 8'is the same as that of the vertical blade 8 of the first embodiment, but according to the present embodiment, the front sliding shaft 8c 'has the upper and lower portions as shown in FIG. The rack bodies 32, 33 are formed longer than the other central shaft portion 8a and the rear sliding shaft 8b by the length of the rack bodies 32, 33 inserted into the long holes 32c, 33c.

In the case 2'constructed as described above, with the rack gear 35 fitted between the pair of front and rear guide members 22 and 23, the operating shaft portion 31 has the support member 21 and the guide plate member 22. , 23 horizontally and rotatably supported. The upper and lower rack bodies 32, 33 are engaged with the rack gear 35 between the guide plate members 22, 23.
Are arranged in the wrong state, and the long holes 32c formed in the respective branch pieces 32b, 33b of both rack bodies 32, 33,
The lower end of the front sliding shaft 8c 'of each vertical blade 8 is rotatably and movably fitted to and supported by 33c. On the other hand, the upper end of the sliding shaft 8c 'is fitted and supported by the insertion hole 2c' formed in the upper wall of the case 2 ', and the lower end of the sliding shaft 8c' is formed in the lower wall of the case 2 '. The inserted insertion hole 2c 'is passed through, and the tip end thereof is fitted and supported in the elongated holes 32c, 33c of both rack bodies 32, 33 as described above.

The point to be noted here is that the plurality of vertical blades 8 are divided into two groups in the present invention. That is, according to the above-mentioned embodiment, the vertical blades 8'are divided into two pieces, left and right, except for the central one, and each branch piece 32 of each rack body 32, 33 is divided into two pieces.
It is divided into b and 33b, and is supported through the long holes 32c and 33c. In this embodiment, since the number of the vertical blades 8'is odd (5), the central one does not participate in the concentrated flow and the diffused flow, and therefore this one positively applies to the rack bodies 32 and 33. However, if the total number of vertical blades 8'is an even number, they are divided into the same number on the left and right sides.

According to the ventilator 1'of the second embodiment constructed as described above, the motor unit is operated in a state where both the link operating projections 6a, 6b are on a straight line parallel to the vertical blades 8 '(see FIG. 9). If the operation knob 34 is rotated to the left or right while the driving of 3 is stopped, the upper and lower rack bodies 32 and 33 alternately move in opposite directions via the rack gear 35. As a result, the front end portions of the vertical blades 8'supported by the rack bodies 32, 33 are subjected to forces that cause deformation in opposite directions for each group. At this time, in the front portion of the central shaft portion 2a of the vertical blade 8 ', the position of the portion of the front link member 12 supported by the blade support member 12d is fixed, and the front end sliding shaft 8c of the vertical blade 8'is fixed. Since both the upper and lower ends of the vertical blade 8'can move in an arc shape inside the insertion hole 2c 'of the case 2', the front end portion of the vertical blade 8'can be the blade supporting member 12d.
The part supported by is curved and deformed to the left and right.

That is, when the operation knob 34 is rotated to the right in FIG. 8, the upper rack body 32 moves to the left,
At the same time, the lower rack body 33 moves to the right. As a result, in the front portion of the vertical blade 8'which is divided into the left and right, the two left-sided sheets are deformed toward the center and the right-sided two sheets are also deformed toward the center as shown by the broken line in FIG. At this time, the air blown from the air outlet becomes a concentrated flow. Here, when the operation knob 34 is rotated to the left, the upper and lower rack bodies 32 and 33 move in the opposite direction to the above, and the vertical blades 8 ′ undergo the state (parallel flow) shown in FIG. At the same time, the two sheets on the right deform to the left, and the two on the right deform to the right to obtain a diffusive flow.

Although all of the illustrated embodiments have been described with respect to the vertical blades, it goes without saying that the wind direction adjusting device of the present invention can also be applied to horizontal blades. In addition, the above-mentioned embodiments exemplify the present invention, and various modifications can be made without departing from the spirit of the present invention.

Further, in the second embodiment, instead of the insertion hole 2c 'in which the arcuate hole and the elongated hole are intersected with each other, the shape of the insertion hole may be an elliptical shape having a laterally long shape. In this case, if the relationship between the relative movement positions of the upper and lower rack bodies 32, 33 is set in advance to an appropriate one, for example, the motor unit 3a is first activated and the vertical blade 8'is S-shaped as described above. The vertical blades 8'are operated by operating the operation knob 34 after deforming it into a desired shape to obtain an arbitrary wind direction.
If the front part of is deformed so as to obtain the desired blowout form of the concentrated flow or the diffused flow, both the left and right or up and down wind directions and the blowout form of the concentrated flow or the diffused flow can be simultaneously and at any angle. It becomes possible to obtain.

[0038]

As is apparent from the above description, the wind direction adjusting device of the present invention is a very simple operation, and the wind direction of the blown air or the blown air form can be separately or simultaneously controlled at any angle. It can be changed.
