Abstract

PURPOSE: To enable protection of a power generation means from damages by providing a power transmission means to block the transmission of extraneous force to the side of the power generation means, when the extraneous force happens to work on a wind direction adjusting blade which is driven to rotate by a drive force of the power generation means. CONSTITUTION: In a wind direction adjustor to be installed in an air conditioner, as a drive shaft 71 is rotated clockwise by a stepping motor 70, a casing 60 linked to the drive shaft 71 is also rotated in the same direction, and first and second rotary blades 31 and 32 of a second rotary member 30 are pushed by first and second protruded parts 62 and 63 of the casing 60 so that the second rotary member 30 is also rotated in the same direction. In addition, a first rotary member 50 is rotated in the same direction through an elastic member 40 to make a wind direction adjusting blade 10 rotate by a specified angle through a shaft 20. At this point, as extraneous force works on the wind direction adjusting blade 10, the elastic member 40 is caused to generate a torsional rotation to absorb a rotating extraneous force, thereby preventing transmission thereof to the stepping motor 70.

Only when the power generating means is rotationally driven, the rotational driving force is transmitted to the wind direction adjusting blade, and when an external force is applied to the wind direction adjusting blade, the external force is not transmitted to the power generating means. It is composed of power transmission means.

The power generating means is composed of a drive shaft connected to the stepping motor and the outer peripheral stepping motor.

Further, the power transmission means includes a first rotating member and a wind direction adjusting blade which are rotated when the wind direction adjusting blade is rotated in one direction by an external force and are fixed when the wind direction adjusting blade is rotated in the opposite direction. By the external force, it is located between the second rotating member that is fixed when rotating in the one direction and is rotated when rotating in the opposite direction, and the first and second rotating members, An elastic member whose both ends are connected to the first and second rotating members, a bush which is sandwiched inside the elastic member, and is further kneaded, and further the rotational driving force of the power generating means is applied to the first and second rotating members. It is composed of a casing that transmits to the member.

The first and second rotating members have the same shape,
It has a shaft hole formed with a single protrusion at its center, and a pair of rotary blades and the like are extended to the outer peripheral edge so as to face each other.

A protrusion formed in the shaft hole of the first rotating member,
The protrusions formed in the shaft hole of the second rotating member are positioned to face each other. The casing has a cylindrical shape in which one end is closed and the other end is open, and the first rotating member, the elastic member, and the second
A rotating member is arranged.

Further, the casing has a pair of protrusions at positions facing each other on the inner peripheral edge thereof, and accordingly, the rotary blades of the first and second rotating members are provided with a pair of protrusions of the casing. Are arranged so as to intersect with each other.

A small hole is bored on each one-sided rotary blade of the first and second rotary members, and both ends of the elastic member are fitted in the holes or the like, so that the first and second rotary members are inserted. The rotating member and the elastic member move mutually in the casing.

[0018]

The drive shaft of the power generating means is coupled to the outer surface of the closed end of the casing of the power transmitting means constructed as described above, and the rotational driving force of the power generating means is transmitted to the power transmitting means.

Further, it is connected to the power transmission means and is rotated by the rotational driving force generated by the power generation means,
The wind direction adjusting blade shaft, which has one end thereof, has a circular cross section partially cut in the longitudinal direction to a length that can be inserted into the open inside of the casing at one end thereof to form a "D" -shaped cross section. .

Therefore, one end of the wind direction adjusting blade shaft having a "D" -shaped cross section is fitted in the shaft holes and the like formed in the first and second rotating members and the elastic member located therebetween. It is inserted into the casing through the inside of the bush, but at this time, the cut surface of the wind direction adjusting blade shaft is fitted into the projections projected into the shaft holes of the first and second rotating members to be joined. Is.

The other end of the wind direction adjusting blade shaft is connected to the first wind direction adjusting blade, a disc is fitted in the vicinity of the middle of the wind direction adjusting blade shaft, and the coupling hole is formed in the disc. A connection link, which is connected to the second wind direction adjusting blade shaft, is fitted. A large number of the connecting links can be provided according to the number of wind direction adjusting blades. Therefore,
It is possible to rotate a large number of wind direction adjusting blades and the like by one power generating means.

The operation of each member of the wind direction adjusting device constructed as described above will be as follows.

When the power generating means rotates in one direction, the casing of the power transmitting means connected to the drive shaft of the power generating means rotates in that direction.

When the casing is rotated, a pair of projecting portions projectingly formed on the inner peripheral edge of the casing has rotor blades and the like of the first and second rotating members that are located opposite to each other around the projecting portion or the like. Inside, the rotor blades and the like placed in the rotation direction can be rotated.

When any one of the first and second rotating members is rotated, the first and second rotating members are interconnected by the elastic member, so that they rotate integrally.

When the first and second rotating members are rotated, the protrusion formed in the shaft hole of the first or second rotating member pushes the cut surface of the wind direction adjusting blade shaft inserted in the shaft hole. , Rotate the power generating means in the direction of rotation.

Here, the projection formed in the shaft hole of each rotating member is formed in the shaft hole of the second rotating member by rotating the first rotating member by a pair of projecting portions of the casing. The formed projection rotates the wind direction adjusting blade shaft, and in the opposite case, the projection of the second rotating member is arranged to rotate the wind direction adjusting blade shaft.

Therefore, the wind direction adjusting blade shaft is rotated in one direction by the power generating means, and the wind direction adjusting blade is rotated at a predetermined angle to adjust the wind direction.

On the other hand, if a rotational external force acts on any one of a large number of wind direction adjusting blades to rotate the wind direction adjusting blade shaft in one direction, a protrusion of the first or second rotating member or the like. Rotate only the protrusions located in the rotation direction of the inside, while the other rotating members remain fixed by the protruding portion of the casing, the rotating member on which the protrusions are formed is aligned with the direction of the external rotation force. It is rotated so that it is separated from the pair of protrusions of the casing.

At the same time, the elastic member connected to the first and second rotating members remains fixed at one end with the other fixed rotating member as a support point, and only at the other end. It is twisted and rotated by the rotation of one rotating member that is rotated by the shaft, and absorbs the external force of rotation.

In the above description, the casing is not rotated by the external rotation force, and the elastic member is twisted and rotated, because the elastic force of the elastic member is set to be smaller than the rotational driving force of the power generating means, and the wind direction is adjusted. This is because the elastic external force applied to the member twists the elastic member to an angle corresponding to the external force and absorbs the external rotational force.

Further, if the external force of rotation is removed, the restoring force of the elastic member will restore the wind direction adjusting blade to its original position.

Direction).

To explain the operation process in detail, in the state shown in FIG.
And, if a signal is sent to the stepping motor 70 so as to rotate the second wind direction adjusting blades 10 and 10A and the like to the right by the angle α (“R” direction), the stepping motor 70 is operated and the drive shaft 71 rotates to the right. The casing 60, which is connected to the drive shaft 71 by the bearing portion 61, also includes the drive shaft 71.
It will rotate to the right with.

When the casing 60 rotates to the right, the right side surface 62A of the first protruding portion 62 of the casing 60 pushes the left side surface 31B of the first rotary blade 31 of the second rotating member 30, and at the same time, the second side surface of the casing 60 moves. Left side surface 63B of the protruding portion 63
Is the right side surface 32A of the second rotary blade 32 of the second rotary member 30.
By pressing, the second rotating member 30 will rotate to the right.

The elastic member 40 allows the first rotating member 50 to
The second rotating member 30 is connected to the second rotating member 30.
When is rotated to the right, the first rotating member 50 is also rotated to the right as the elastic member 40 is rotated.

Here, the rotational resistance force of the wind direction adjusting means 3 is
Since the elastic force of the elastic member 40 is set to be much smaller than that of the elastic member 40, the elastic member 40 is integrally rotated rightward together with the first and second rotating members 50 and 30 without being twisted and deformed.

When the first rotating member 50 rotates to the right, the first rotating member 50 moves to the first position at the position where the casing 60 shown in FIG.
A protrusion 55 formed on the right side of the shaft hole 53 of the rotating member 50.
Pushes the cutting surface 21 of the first wind direction adjusting blade shaft 20 to rotate it to the right, and the first wind direction adjusting blade 10 is rotated in the arrow direction (“X” direction) shown in FIG. Further, the second airflow direction adjusting blade shaft 20A connected to the first airflow direction adjusting blade shaft 20 by the connecting link 23 is also rotated to the right, and the second airflow direction adjusting blade 10A is also rotated in the same direction as the first air direction adjusting blade 10. Then, the blower opening 11 is opened by an angle corresponding to the instructed rotation angle α.

By the above-mentioned operation, the first and second wind direction adjusting blades 10, 1 are adjusted in a state where the rotation angles of the first and second wind direction adjusting blades 10, 10A are adjusted.
When the external rotation force acts on any one of 0A and the like, the external rotation force is not transmitted to the power generating means 1. However, the operation of each member in this case is as follows. Is.

In FIG. 5, when the power transmission means 2 is rotated by the angle α and the wind direction adjusting means 3 is adjusted in angle, an external rotational force in the “Y” direction acts on the wind direction adjusting means 3 to cause the casing 60 to rotate. Inside, the first rotating member 50

As shown in FIG. 4, the power transmission means 2 is rotated by the angle α, and the first airflow direction adjusting blade 10 is opened in a state in which the blower port 11 is partially opened by the angle α.
When a rotational external force in the "Y" direction is applied to the first air flow direction adjusting blade 10, the first air flow direction adjusting blade 10 is rotated in a direction of closing the blower opening 11, and accordingly, the first air flow direction adjusting blade shaft 20 rotates counterclockwise. .

Here, in order for the external force of rotation to forcibly rotate the first or second wind direction adjusting blade 10, 10A, etc., the elastic force of the elastic member 40 must be exceeded.
Further, the elastic force of the elastic member 40 is designed to be smaller than the driving force for forcibly rotating the power generating means 1, and if an external rotating force that exceeds the elastic force acts on the wind direction adjusting means 3, the power is reduced. The casing 60, which is directly connected to the generating means 1, allows the elastic member 40 to twist and rotate when stopped.

That is, when the first wind direction adjusting blade shaft 20 rotates counterclockwise (in the "L" direction), the first rotary blade 31 and the second rotary blade 32 of the second rotary member 30 respectively have the first rotary blade of the casing 60.
And the first projecting portion 62, 63 while being fixed by the first
The protrusion 55 of the first rotating member 50 located on the right side of the cutting surface 21 of the wind direction adjusting blade shaft 20 is pushed by the rotation of the cutting surface 21 and is rotated left.

Therefore, the first rotary member 50 is rotated counterclockwise while the second rotary member 30 is fixed, and accordingly, the elastic member connected to the coupling hole 34 of the first rotary blade 31 of the second rotary member 30. While the rear end 44 of the 40 is fixed, the front end 43 of the elastic member 40, which is connected to the coupling hole 54 of the first rotary blade 51 of the first rotary member 50, is rotated leftward together with the first rotary member 50, and the external force of the rotation is applied. Will be absorbed.

That is, when only one of the first and second rotating members 50 and 30 of the wind direction adjusting means 3 is rotated by the external force of rotation, the rotational driving force of the power generating means 1 causes Elastic member 4 when the wind direction adjusting means 3 is rotated
Contrary to 0 being rotated without torsional deformation, one end of the elastic member 40 is fixed and only the other end is rotated and twisted and rotated, so that even if an external force of rotation acts, Since the generating means 1 is not rotated, the stepping motor 70 can be protected.

Further, as shown in FIG.
When the rotating member 50 is rotated counterclockwise by the angle β and the external rotating force is removed, the elastic restoring force of the elastic member 40 causes the first rotating member 50 to rotate to the right, and the position shown in FIG. By being restored to 1, the wind direction adjusting blades 10 and 10A and the like can maintain the original adjusted angle.

In FIG. 3, the elastic member 40 is rotated by an external force.
Is left side (“L” direction) or right side (“R” direction)
The maximum rotation angle of 90 degrees that can be rotated is displayed.

That is, an external force for rotating the elastic member 40 in the leftward direction ("L" direction) acts, and the second rotating member 30 and the rear end 44 of the elastic member 40 are fixed, and the elastic member 4 is fixed.
If the front end 43 of 0 is twisted and rotated, and the first rotary member 50 is continuously rotated counterclockwise, the first rotary blade 5 of the first rotary member 50 is rotated.
The left side surface 51B of No. 1 is rotated by 90 degrees so as to be locked to the left side surface 63B of the second protruding portion 63 of the casing 60, and further, the right side surface 52A of the second rotary blade 52 of the first rotating member 50 is It is rotated 90 degrees and is locked on the right side surface 62A of the first projecting portion 62 of the casing 60, so that it cannot rotate any more.

First or second wind direction adjusting blade 10, 10
If a rotational external force acts on A or the like in the direction opposite to the direction described above, that is, in the “X” direction shown in FIG. 2, the casing 60 and the While the first rotating member 50 and the front end 43 of the elastic member 40 remain fixed, the second rotating member 30 and the rear end 44 of the elastic member 40 absorb the external force of rotation while being rotated clockwise (R direction). Therefore, the external rotation force is not transmitted to the power generation means 1.

FIG. 6 is a sectional view showing another embodiment of the present invention, and FIG. 6A shows the outer surface of the first rotating member 50 and the casing when the wind direction adjusting device of the present invention is operated. In order to prevent mutual contact between the inner wall surface of 60, the outer surface of the second rotating member 30, and the disk 22 installed on the first airflow direction adjusting blade shaft 20, the first and second rotating members are prevented. Fifty,
The figure shows that round protrusions 56 and 36 are formed in the columnar direction on 30 and the like.

Further, FIG. 6B shows that both ends 4 of the elastic member 40 are rotated when the first and second rotating members 50 and 30 are rotated.
