[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal louver device provided at an air outlet of an air conditioner. The present invention relates to a horizontal louver device of an air conditioner that can be switched at a low cost.

[0002]

2. Description of the Related Art FIG. 5 shows an indoor unit 1 of an air conditioner. The indoor unit 1 exchanges indoor air sucked from a suction panel 2 on the front thereof with an internal heat exchanger (not shown), and blows it out as a cool air or a hot air from an outlet 3 opened at a lower portion. . The outlet 3 is provided with a horizontal louver 4 for deflecting the blown air vertically. The horizontal louver 4 has support shafts (not shown) provided at both ends thereof, which are rotatably supported on both sides of the air outlet 3, and is rotatable around the support shaft. Such a horizontal louver 4
The attachment angle is changed manually or electrically. Conventionally, this type of horizontal louver 4 has been driven either manually or only electrically.

[0003]

[Problem to be solved by the invention] However, since the cost of the electric motor is higher than that of the manual motor, it is necessary to sell both the manual product and the electric product for one kind of indoor unit 1 from the viewpoint of business policy. occured. From a manufacturing standpoint, a louver structure that can easily switch between manual operation and electric operation at a low cost with a minimum number of component changes has been desired, but has not been realized. That is, it is not appropriate in terms of cost to replace all the louver movable parts manually and electrically, and it is desirable to share the parts as much as possible.

An object of the present invention, which has been made in view of the above circumstances, is to easily and inexpensively reduce the cost of sharing the parts with respect to whether the horizontal louver has an electric drive structure or a manual drive structure. An object of the present invention is to provide a horizontal louver device of an air conditioner that can be switched.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 shows a manual / electric horizontal louver 4 according to this embodiment. As shown, support shafts 5 are provided at both ends of the horizontal louver 4. These support shafts 5
The louver 4 is inserted into the bearing of the air outlet 4 of the indoor unit 1 shown in FIG. At one end of the horizontal louver 4, a protrusion 6 formed in a track shape along the louver 4 is provided adjacent to the support shaft 5. This protrusion 6
The part 6a is formed so as to project from the louver edge 4a. A groove 7 is formed in the protrusion 6 along the blade direction of the louver 4. The groove 7 functions as a guide groove for an engagement pin 13 of a crank lever 14 described later.

On the other hand, the mechanical housing 8 at one end of the air outlet 3 of the indoor unit 1 has a geared motor 9 with a crank lever when the horizontal louver 4 is of an electric drive structure, and a geared motor 9 with a manual drive structure. The holding member 10 shown in FIG. 3 is selectively attached.

The geared motor 9 with a crank lever is
A crank lever 14 having an engaging pin 13 eccentric from the rotation shaft 12 is attached to a rotation shaft 12 of a geared motor 11 whose rotation angle can be freely adjusted. The engagement pin 13 of the crank lever 14 is inserted into a guide groove 7 formed in the projection 6 of the horizontal louver 4. When the horizontal louver 4 has an electric drive structure, the geared motor 9 with the crank lever is provided in the mechanical housing portion 8 at one end of the outlet 3 and its rotation is controlled by a remote control operation or the like. According to this configuration, the geared motor 11
Is rotated, the guide groove 7 is provided eccentrically from the support shaft 5 of the louver 4, so that the engaging pin 13 of the crank lever 14 is guided by the rotation as shown in FIG. The louver 4 moves up and down around the support shaft 5 while reciprocating in the groove 7, and the blown air is deflected up and down.

The pressing member 10 is formed by punching and bending a spring plate into a shape surrounding the protrusion 6 at the end of the horizontal louver 4 as shown in FIG. 3 and FIG. 1 (b). ing. That is, the holding member 10 has the holding portion 15 to which the protrusion 6 of the horizontal louver 4 is abutted to position the louver angle, and the stoppers 16 and 17 to limit the movable angle range of the louver 4. The holding portion 15 is composed of a plurality of digits 18 which are vertically spaced apart from each other.
When the protrusion 6 of the horizontal louver 4 gets over the louver angle, the louver angle is changed stepwise, and the louver angle is fixed by fitting the protrusion 6 between the beams 18. At this time, each girder 18 is slightly deformed, but there is no durable problem because it is made of an elastic spring plate. The stoppers 16 and 17 are plate members arranged so as to sandwich the holding portion 15 from above and below, and prevent the protrusion 6 of the horizontal louver 4 from going too far up and down, thereby limiting the movable angle range of the louver 4. It is. When the horizontal louver 4 is manually driven, the holding member 10 is screwed to the mechanical housing 8 instead of the geared motor 9 with the crank lever.

According to the above configuration, the projection 6 provided at the end of the horizontal louver 4 functions as a notch for manual operation and also functions as a drive groove for electric power. 4 itself can be made into a common part. In other words, the switching between manual and electric only needs to selectively attach the motor 9 with the crank lever or the holding member 10 to the outlet 3 of the indoor unit 1 without changing the horizontal louver 4 itself. Therefore, for the indoor unit 1 of the same type, the driving method of the horizontal louver 4 can be easily switched between manual and electric at low cost.

When the track-shaped projection 6 is provided at the end of the horizontal louver 4 eccentrically from the support shaft 5 as described above, the position of the center of gravity of the louver 4 depends on the weight of the projection 6. About 5mm from the extension of. As a result, when changing the angle of the louver 4 from vertical to horizontal, the louver 4 descends at a stretch and the movement becomes unnatural, which has a bad influence on the blowing wind.

Therefore, as shown in FIG. 4, a weight member 19 (counter weight) is provided at the edge of the louver 4 in the blowing direction in a direction opposite to the direction in which the position of the center of gravity is shifted with the support shaft 5 interposed therebetween.
The position G of the center of gravity of the louver 4 was made to coincide with the position of the support shaft 5. Specifically, one edge of the louver 4 is folded, and the folded portion 20 is used as the weight member 19. As a result, the moment of inertia of the louver 4 around the support shaft 5 is reduced, and the louver 4 smoothly rotates in response to an input from the motor 11 during electric driving. Further, the folded portion 20 functions not only as the weight member 19 but also as a strength member of the louver 4. Instead of folding, another weight plate may be bonded to the edge of the louver 4.

[0018]

As described above, according to the “horizontal louver device of the air conditioner” according to the present invention, the horizontal louver itself is shared as to whether the horizontal louver has an electric drive structure or a manual drive structure. Therefore, switching can be performed easily and at low cost.
