The present invention relates to an assembly structure of a shutter and a hinge member of an auto shutter for an air conditioner, and more particularly, the opening and closing of a discharge port of an air conditioner through an operation of a transfer device and a driving motor consisting of a screw-type rotating rod and a bushing, and a lowering of the shutter. In the auto shutter, when the assembly between the shutter and the bushing of the transfer device by a hinge member, the hinge drive between the shutter and the hinge member can be easily assembled without a separate fastener such as a nut and a ring between the shutter and the hinge member. A shutter and hinge member assembly structure of an auto shutter for an air conditioner is provided.

As is well known, the air conditioner is classified into a wall-mounted air conditioner and a stand-type air conditioner according to an installation method, and according to the structure, an air conditioner is divided into an integrated air conditioner provided with an indoor unit and an outdoor unit, and a separate air conditioner that separates an indoor unit and an outdoor unit separately.

Here, among the separate type air conditioners, a compressor for compressing a refrigerant at high temperature and high pressure and a condenser for condensing the compressed refrigerant are provided in the outdoor unit, and an evaporator for heat-exchanging the condensed refrigerant is provided in the indoor unit.

The indoor unit of such a conventional separate air conditioner has a cabinet in which a predetermined component part is mounted, and a front cover which forms a front surface of the cabinet.

A suction port for sucking air in the room is formed in the lower region of the front cover, and a discharge port for discharging the heat-exchanged air is provided in the upper region of the suction port.

The discharge port is provided with an auto shutter capable of moving between an open position for opening the discharge port and a closed position for closing the discharge port.

When the air conditioner operates, the auto shutter opens the discharge port to discharge heat exchanged from the discharge port, and closes the discharge port when the operation of the air conditioner is stopped.

On the other hand, there are a number of techniques for the driving method of the auto shutter, as an example is disclosed in Korean Patent Application No. 2000-32181.

The disclosed technique is to open and close the auto shutter by the operation of the rack and pinion by the motor.

However, in most conventional air conditioners, the driving method of the auto shutter is opened and closed by the interaction between the rack and the pinion, and thus has a relatively complicated structure, so that the failure rate is relatively high, thereby increasing maintenance costs. It shows a downside.

Accordingly, the present applicant has come to propose a way to drive the auto shutter more effectively compared to the power used by opening and closing the auto shutter in a new way.

That is, the patent application No. 2004-118412 (filed on Dec. 31, 2004, filed by the applicant of the present application, the name of the invention: the auto shutter operating device of the air conditioner) is a screw thread formed ball screw (hereinafter referred to as 'rotating rod') A new method of auto shutter operation is disclosed, which allows the shutter to be raised and lowered through a shaft and a lifting piece (hereinafter referred to as a bushing).

As described above, in the case of the auto-shutter operating device previously filed by the applicant, when the rotary rod rotates under the rotational force of the driving motor, the shutter is inserted into the rotary rod and the bushing coupled with the screw moves up and down to open and close the discharge port of the air conditioner. will be.

Here, in the case of the pre-applied auto shutter operation device, two brackets for assembling the slider face each other with a predetermined gap on the rear surface of the shutter, and each of the brackets has fitting holes through which the shafts of the slider can be fitted. It has a formed structure.

Therefore, since both shafts of the slider are fitted in the fitting holes of the respective brackets and are fixed by tightening nuts on both sides, the assembling process is cumbersome, requiring a separate fastener such as a nut. Had a problem.

In particular, the auto shutter operation device has a problem in that the overall structure is complicated because the drive motor and the ball screw are rotated by an angle through the angle rotation part to perform the position correction according to the vertical movement of the auto shutter.

 The present invention has been made to solve the above problems, an object of the present invention, the opening and closing of the discharge port of the air conditioner through the operation of the drive and the drive motor and the drive motor consisting of a screw-type rotating rod and bushing In the shutter, when fastening and assembling between the shutter and the bushing of the transfer apparatus by a hinge member, a hinge can be driven between the shutter and the hinge member by simply assembling without a separate fastener such as a nut and a ring between the shutter and the hinge member. It is to provide a shutter and hinge member assembly structure of the auto shutter for the air conditioner to facilitate the position correction.

The present invention for achieving the above object, in the air conditioner having an outer casing having a discharge port, an auto shutter for opening and closing the discharge port, the shutter for opening and closing the discharge port and the shutter for opening and closing the shutter A drive motor rotatable in a forward and reverse direction provided to provide a driving force, a rotating rod coupled to the driving motor to rotate, a bushing coupled to the rotating rod to move up and down along the rotating rod, and one end coupled to the shutter and the other end of the Consists of a hinge member coupled to the bushing; Hinge pins protrude from both sides of the hinge member coupled to the shutter, and a hinge member fastening portion is formed on the back of the shutter, and a hinge pin of the hinge member can be elastically fitted to the hinge member fastening portion. It is achieved by providing a shutter and the hinge member assembly structure of the auto shutter for the air conditioner characterized in that the receiving groove is formed.

Here, the hinge member has a structure in which one end coupled to the shutter and the hinge is formed in a rectangular body, and hinge pins are formed on the left and right sides of the body, and the other end coupled to the bushing is formed by an axial link portion integrally extending from the body. The hinge member fastening portion of the shutter is characterized in that the pin receiving groove is formed on the bracket while having a bracket structure protruding at a predetermined interval so that the body of the hinge member is seated.

In particular, the hinge member may be formed integrally with the bushing.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

As shown in FIG. 1, an air conditioner according to an exemplary embodiment of the present invention includes an outer casing 10 having a predetermined device component mounted therein and having an open front, and coupled to a front surface of the outer casing 10. It has a front cover 20 that forms the front of the air conditioner.

Here, a suction port 21 for inhaling indoor air into the outer casing 10 is formed in the lower side region of the outer casing 10.

In addition, a discharge port 22 for discharging cold air formed by heat exchange by a heat exchanger (not shown) is formed in an upper region of the front cover 20.

In the discharge port 22, an auto shutter S for selectively opening and closing the discharge port 22 when the air conditioner is operated and stopped is provided to be movable up and down.

An operation panel 30 is provided between the intake port 21 and the discharge port 22 to operate and stop the air conditioner, and to control the strength and blowing direction of the heat exchanged air, the operation of the auto shutter S, and the like. .

Therefore, a series of control such as operation of an air conditioner related to cooling can be performed through a button or a remote controller provided in the operation panel 30.

Meanwhile, as shown in FIGS. 2A and 2B, the louver frame 40 having the discharge port 22 is separately provided in the upper region of the outer casing 10, which is the upper region of the front cover 20. do.

In addition, the discharge port 22 is provided with a horizontal blade 42 and a vertical blade 43 for adjusting the direction of the heat-exchanged air.

At this time, the front discharge port 22 of the horizontal and vertical blades (42, 43) between the open position (see Fig. 4b) for opening the discharge port 22 and the closed position (see Fig. 4a) for closing the discharge port 22 The movable auto shutter S is installed.

The auto shutter S may be classified into a shutter 50, a transfer device 60, and a driving motor 70.

That is, the shutter 50 performs an operation of moving between the open position of the discharge port 22 and the closed position of the discharge port 22 by the interaction of the transfer device 60 and the driving motor 70. will be.

Here, a plurality of guide rail protrusions 51 extending outwardly are formed at upper and lower ends of both sides of the shutter 50, and guides for receiving and guiding the guide rail protrusions 51 on both side surfaces of the louver frame 40. The rail part 41 is formed.

In this case, the guide rail portion 41 includes a vertical section 41b and a horizontal section 41a extending slightly inclined forward from the end of the vertical section 41b.

That is, when the guide rail protrusion 51 of the shutter 50 is positioned in the horizontal section 41a past the vertical section 41a of the guide rail portion 41, the shutter 50 slightly protrudes forward. The outlet 22 is placed in a position to completely close.

On the other hand, as shown in Figure 3a, the conveying device 60 as a means for driving the shutter 50 according to the present invention, a screw-type rotating rod 61 is coupled to the drive motor 70 to rotate And a bushing 62 inserted into and coupled to the rotating rod 61 to move up and down along the rotating rod 61, and one end coupled to the shutter 50 and the other end to the hinge member 63 coupled to the bushing 62. do.

Here, the rotating rod 61 has a rod shape having a predetermined length and is formed of a screw type with a screw groove 61a formed thereon so as to be seated on the rotating rod seat 44 provided in the louver frame 40. do.

In addition, a screw protrusion (not shown) is formed on the inner circumferential surface of the bushing 62 to correspond to the screw groove 61a of the rotating rod 61 so as to rotate the screw.

In particular, as illustrated in FIGS. 3B and 3C, hinge pins 63c protrude from both sides of the hinge member 63 coupled to the shutter 50, and a bracket (b) is formed on a rear surface of the shutter 50. 54) the hinge member fastening portion is formed, and also has a structure in which the pin receiving groove (54a) can be elastically fitted to the hinge pin (63c) of the hinge member 63 to the hinge member fastening portion.

That is, the hinge member fastening portion formed on the rear surface of the shutter 50 has a structure of the bracket 54 protruding left and right at a predetermined interval to allow the hinge member 63 to be seated, and the pin on the bracket 54. The receiving groove 54a is formed.

At this time, the opening of the pin receiving groove (54a) is formed to be somewhat narrower than the diameter of the hinge pin (63c), when the hinge pin (63c) is fitted, the hinge pin (63c) must be pushed at a rather strong pressure It can be inserted, and after the hinge pin is coupled, the opening of the pin receiving groove is elastically restored to the initial state.

Therefore, the hinge pin 63c inserted into the pin receiving groove 54a does not pull out the hinge pin 63c from the pin receiving groove 54a unless it is forcibly pulled out.

And, as shown in Figure 3c, the hinge member 63 is formed with a rectangular body (63a) of one end to be hinged to the shutter 50 is hinge pins on the left and right of the body (63a) It has a structure provided with (63c), the other end has a structure in which the intermediate portion extending from the rectangular body (63a) integrally formed in the axial link portion (63b) somewhat bent.

In this case, a fitting groove is formed in the link part for coupling the bushing, and a fixing protrusion (not shown) is provided on the bushing to correspond to the fitting groove.

In particular, the bushing 62 and the hinge member 63 may be separately manufactured and assembled as described above, but the bushing 62 and the hinge member 63 may be integrally manufactured.

According to the assembly structure of the shutter 50 and the hinge member 63 as described above, one end of the hinge member 63 formed of a rectangular body 63a is between the bracket 54 provided on the rear surface of the shutter 50. At the same time, the hinge pin 63c and the pin receiving groove 54a are engaged with each other so that the hinge pin 63c is elastically fitted to the pin receiving groove 54a.

Therefore, the assembly structure itself of the shutter 50 and the hinge member 63 is relatively very simple compared to the shutter and the slider described in the prior art, and in particular firmly fixed without the use of separate fasteners such as nuts and rings It can be eliminated the hassle of working process.

In addition, since the shutter 50 and the hinge member 63 are assembled in a hinge coupling structure, the position correction can be easily performed in the process of moving the shutter 50 along the guide rail portion 41. There is also an advantage.

On the other hand, the drive motor 70 is a conventional motor that can be rotated in the forward and reverse directions that can be commonly encountered in the periphery, it is mounted on the drive motor mounting portion 45 (see Fig. 2b) provided in the louver frame (40).

In addition, the stop position of the shutter 50 according to the ascending and descending of the shutter 50, that is, the stop point of the driving motor 70, may detect the movement position of the shutter 50 by the proximity sensor 46. Control by means.

In this case, the sensing means is a proximity sensor 46 provided on one side of the louver frame 40, the sensing bar (63d) and the shutter (integral formed integrally on the lower end of the hinge member 63 coupled to the bushing 62) It consists of a sensing bar 53 provided on one side upper end of the 50.

Of course, the sensing bar 63d may be formed integrally with the bushing 62 instead of the hinge member 63.

That is, when the shutter 50 moves upward to close the discharge port 22, the sensing bar 63d provided in the bushing 62 or the hinge member 63 approaches and approaches the proximity sensor 46. At this time, the driving motor 70 is stopped so that the movement of the shutter 50 stops, and when the shutter 50 moves downward to open the discharge port 22, the sensing bar 53 provided in the shutter 50. ) Approaches the proximity sensor 46 and coincides with the proximity sensor 46, the drive motor 70 is stopped so that the movement of the shutter 50 stops.

Looking at the operation of the auto shutter (S) in the air conditioner having such a configuration as follows.

As shown in FIGS. 4A and 4B, when the air conditioner is to be used in the stopped state of the air conditioner (moving from FIG. 4A to FIG. 4B), first, the discharge port 22 is normally closed to prevent the inflow of foreign matters. The auto shutter S is operated and the discharge port 22 is opened, so that the air conditioner can be used.

To this end, first, the user drives the air conditioner by operating the manipulation panel 30 using a manual or a remote controller.

Accordingly, the drive motor 70 starts driving to rotate the rotating rod 61 in one direction.

Then, the bushing 62 inserted and coupled to the rotary rod 61 is lowered by a screw action, and at the same time, the shutter 63 connected to the bushing 62 and the hinge member 63 starts to descend.

That is, the guide rail protrusion 51 of the shutter 50 located in the horizontal section 41a of the guide rail portion 41 corresponding to the closed position of the discharge port 22 is a horizontal section of the guide rail portion 41. It starts to move toward the vertical section 41b from 41a.

At this time, the hinge of the shutter 50 and the hinge member 63 while the guide rail protrusion 51 of the shutter 50 extends from the horizontal section 41a of the guide rail portion 41 to the vertical section 41b. As the shutter 50 moves by a hinged angle by a coupling relationship, the movement path of the shutter 50 is smoothly compensated.

Then, when the guide rail protrusions 51 of the shutter 50 reach the vertical section 41b of the guide rail portion 41, the bushing is rotated by the rotation of the rotating rod 61 by the operation of the driving motor 70. 62 and the hinge member 63 is lowered so that the shutter 50 can open the discharge port 22 as shown in Figure 3b.

At this time, when the shutter 50 stops moving, the sensing bar 53 provided in the shutter 50 approaches the proximity sensor 46 to detect the coincidence, and thus, the control unit (not shown) drives the driving motor 70. By stopping.

On the other hand, when looking at the closing process of the auto shutter (S), if the user operates the operation panel 30 to stop the operation of the air conditioner (moving from Figure 4b to Figure 4a), the drive motor 70 of the The rotary rod 61 is rotated by the driving.

Of course, in this case, the driving motor 70 rotates in the opposite direction to the rotation of the driving motor 70 when the shutter 50 is lowered. Accordingly, the rotating rod 61 may also lower the shutter 50. It will rotate in the opposite direction.

When the rotating rod 61 rotates in the opposite direction, the bushing 62 moves up along the rotating rod 61 to move the hinge member 63 upward.

Then, the shutter 50 is raised while the guide rail protrusions 51 of the shutter 50 start to move up along the vertical section 41b of the guide rail portion 41.

The guide rail protrusions 51 of the shutter 50 are positioned in the horizontal section 41a through the vertical section 41b of the guide rail portion 41 by the continuous operation of the driving motor 70, thereby providing the shutter 50. Can be moved to the perfect closed position of the discharge port 22 (FIG. 3A).

Of course, at this time, when the shutter 50 stops moving, the sensing bar 63d formed on the bushing 62 or the hinge member 63 approaches the proximity sensor 46 to detect the coincidence with the control unit, which is not shown. By stopping the drive motor 70 is made.

Although the above description has been made by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following patent will be described by those skilled in the art to which the present invention pertains. It will be understood that various modifications and variations are possible within the scope of the claims.

As described above, according to the present invention, a bracket having pin receiving grooves is provided on the rear surface of the shutter, and hinge pins are provided on the left and right sides of the body and the body of the square at one end of the hinge member, thereby providing a bushing of the shutter and the transfer device. When fastening and assembling between the hinge members, the shutter can be easily assembled without a separate fastener such as a nut and a ring between the shutter and the hinge member, as well as a hinge drive between the shutter and the hinge member after assembly, thereby moving the shutter. There is an effect that the position correction is easy in the process.
