Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air blowing device for a vehicle air conditioner or other general cooling/heating air conditioner.

Prior Art For example, in Japanese Utility Model Application Publication No. 55-6768, wind direction adjustment plates 7a and 7b supported in a swingable manner are provided with an operating plate 6.
A configuration is disclosed in which the arms 4a and 4b are connected to each other via a and 6b, and one end of the arms 4a and 4b is connected to the rotating member 3. Then, the arm 4 is inserted into the elongated hole 40 formed in the arms 4a, 4b.
Bolts 5 are attached to both sides of a and 4b via spring members 51.
0b loosely fit, and the tip of the bolt 50b is attached to the support member 5.
At the same time, the wind direction adjustment plate 7 is screwed onto the supporting member 52.
It pivotally supports actuating plates 6a and 6b which are connected to actuating plates 6a and 7b.

Therefore, by rotating the rotating member 3 by the motor 1, the arms 4a, 4b, the actuating plate 6a,
The wind direction adjustment plates 7a and 7b are swung through the airflow direction adjustment plates 6b.

Problems to be Solved by the Invention According to the prior art as described above, the actuating plates 6a,
The support structure between the arm 6b and the arms 4a and 4b has a large number of parts, such as a bolt 50b, a support member 52, a spring member 52, etc., and the structure is complicated.

Further, it is necessary to form elongated holes 40 in the arms 4a, 4b, and the cross-sectional dimensions of the arms 4a, 4b are large in terms of strength, resulting in the disadvantage that the resistance of passing air cannot be reduced.

Furthermore, since the arms 4a and 4b have a large number of convex portions and protrusions such as the bolts 50b, there is a problem in that wind noise is not reduced.

Furthermore, the support member 52, the actuating plates 6a, 6
b, and the wind direction adjustment plates 7a, 7b are not slidably engaged, so the wind direction adjustment plates 7a,
As the arm 7b rotates, the arms 4a and 4b are displaced toward the center of rotation, and therefore, there is a problem in that smooth movement cannot be ensured.

On the other hand, it is necessary to arrange the rotating member 3 as a means for connecting the arms 4a and 4b and the motor 3 that rotatably supports the rotating member 3 in the gap between the wind direction adjusting plates 7a and 7b. The problem is that the area becomes wider.

Further, since the location where the motor 3 is disposed is limited to the gap between the wind direction adjustment plates 7a and 7b, there is a problem in that the mounting position cannot be arbitrarily selected.

The present invention solves the above-mentioned problems of the prior art, and is designed to maintain cool or warm air by blowing intermittent air to personnel indoors.The present invention has a simple structure, reduces air resistance, and reduces wind noise. Another object of the present invention is to provide an air blowing device for an air conditioner whose layout can be selected relatively freely.

Means for Solving the Problems A driving rod that reciprocates in the left-right direction along a guide member by a driving source, a louver device including a plurality of louvers, and a structure in which the driving rod and the louver device are slidable relative to each other. The louver device is made to swing by the reciprocating movement of the driving rod. A driving rod is inserted into a hole formed in the supporting member, and a louver device that slidably holds the supporting member relative to the driving rod by an elastic member provided in the supporting member is inserted in the longitudinal direction of the driving rod. The support member is slidably coupled to the support member in a direction perpendicular to the support member.

Function The left and right louvers swing in opposite directions due to the reciprocating movement of the drive rod.

By shifting the position of the support member with respect to the driving rod, the direction in which the louver swings can be changed and the direction of the wind can be changed.

Since the support member and the louver are slidably connected in a direction perpendicular to the longitudinal direction of the driving rod, when the louver swings, no unreasonable force is generated on the supporting portion of the driving rod and the louver.

Embodiment In FIGS. 1 and 4, 1 is a geared motor, 2 is one end (left end in the figure) connected to the geared motor 1, and the other end (right end in the figure) is connected to the gear 3 at the tip.
each connected to a drive transmission arm 3 having a
A driving rod 2 is slidably attached to a guide member (not shown), and a louver device 4 consisting of a plurality of louvers is attached to the center of an air outlet C on the left side of an air conditioner (not shown). The louver device 4 is swingably attached via the support member 2a so that the louver device 4 is located at the support member 2a. The air outlet C swings periodically to blow out air from the air outlet C. Reference numeral 6 denotes a drive rod that is slidably attached to a guide member (not shown) on the axis of the drive rod 2, and is attached to the tip of a drive transmission arm 7 whose one end is connected to one end of the drive rod 6 with a pin. The provided gear 7a is connected to the drive transmission arm 3.
It meshes with the gear 3a to form a gear mechanism. The drive rod 6 also includes the drive rod 2.
Similarly, a louver device 4 made up of a plurality of louvers is swingably attached to the center of the air outlet D on the right side via a support member, and the driving rod 6 is connected to a geared motor. When the drive rod 2 reciprocates in the left-right direction due to the operation of the drive rod 1, the drive rod 2 reciprocates via the drive transmission arm 3, the gear mechanism G, and the drive transmission arm 7. Therefore, the louver device 4 attached to the drive rod 6 is configured to blow out air from the air outlet D on the right side. Note that the reference numeral 5 in Figure 2
5 shows a switch for this device, and by turning on the switch 5, this device is activated.

Note that the support member 2a, as shown in FIG.
It supports the louver device 4 and is slidably attached to the drive rods 2 and 6 via leaf springs or the like.

One embodiment of the device of the present invention is constructed as described above, and when the switch 5 is turned on, the geared motor 1 starts operating, and the left and right drive rods 2, 6
moves back and forth. As the drive rods 2 and 6 reciprocate, the left and right louver devices 4 swing, and intermittent air is sent into the room from the left and right air outlets C and D, effectively cooling the interior of the room. Warm air is sent to even out the indoor temperature distribution.

In addition, by appropriately sliding the louver device 4 with respect to the drive rods 2 and 6 in the vehicle interior, the range in which the louver device 4 swings, that is, the range in which the air blows out can be freely changed to the left or right. It is possible to realize fine-grained air conditioning according to the number of passengers and the preferences of the passengers. Note that this operation can be performed by the occupant displacing the louver device 4 left and right with respect to the drive rod from within the vehicle interior, and therefore has the advantage of being simple.

Effects of the invention A pair of louver devices, each consisting of a plurality of rotatably arranged louvers, are attached to the left and right outlets, and are connected to each louver device via a support member, and are connected along the longitudinal direction of the louver devices. a pair of drive rods arranged so as to be reciprocally movable; a connecting means for connecting the two drive rods to each other; and a drive source connected to one of the drive rods;
In an air blowing device for an air conditioner in which the louver device swings as the driving rod reciprocates, the driving rod can slide into a hole formed in the support member via an elastic member. The supporting member and the louver device are configured to be slidable in a direction perpendicular to the longitudinal direction of the driving rod, and the connecting means has a gear portion at one end. It consists of a pair of drive transmission arms, the other end of which is connected to the drive rod, and one end of each of the drive transmission arms is rotatably supported so that the gear portions of the arms mesh with each other. It produces the following effects.

Since the driving rod is inserted into a hole formed in the support member and fixed by the biasing force of the elastic member, the number of parts is small and the structure is simple.

Further, since there is no need to form any support mechanism on the driving rod, the cross-sectional area of the rod can be reduced, and the resistance of the air passing therethrough can be reduced.

Furthermore, since there are no protrusions such as bolts or nuts on the drive rod and the support member, wind noise can be reduced.

Furthermore, since each louver is slidably engaged with the support member, it is possible to prevent the drive rod from being displaced toward the center of rotation as the louver rotates, and therefore, the drive rod can be smoothly moved. You can ensure good movement.

On the other hand, since the means for connecting the drive rods is a set of drive transmission arms, it does not take up much space.
In particular, the distance between the central portions of both louver devices can be narrowed.

Further, in order to swing the louver, it is sufficient to reciprocate any one of the drive rods mentioned above, and therefore, the mounting position of the drive source can be arbitrarily selected.
