Description

Air conditioner

The present invention relates to an air conditioner, and more particularly, to a mounting structure of a louver provided at an air discharge port.

The air outlet of the air conditioner is provided with a louver for adjusting the direction of the heat exchanged air uniformly, and sometimes locally. Fig. 17 is a sectional view showing a general structure of a conventional air conditioner, and Fig. 18 is an enlarged cross-sectional view of the air discharge port. The air conditioner is composed of an indoor unit and an outdoor unit. In the present specification, the air conditioner refers to an indoor unit.

Specifically, the air conditioner as the indoor unit includes a housing 1 designed to be hung on the interior wall. In this example, an air inlet 2 is provided on the front and top surfaces of the housing 1, respectively, and the air discharge port 5 is provided. Is provided in the front lower part of the housing 1. The heat exchanger 3 and the blower fan 4 are provided in the air passage from the air inlet 2 to the air outlet 5 in the housing 1.

The air discharge port 5 is provided with, for example, two longitudinal louvers 7 and 8 for adjusting the wind direction in the longitudinal direction and a plurality of horizontal louvers 6 for adjusting the wind direction in the lateral direction. In general, the longitudinal louvers 7 and 8 are located in front of the horizontal louvers when the air outlet 5 is viewed from the outside (inside), and is vertically extended from the upper wall portion 5a of the air outlet 5 to the supporting piece. As a result, the rotary shafts 7a and 8a are supported to be substantially horizontal. That is, the longitudinal louvers 7 and 8 are rotatable in the longitudinal direction within a predetermined angle range about the horizontal rotation shafts 7a and 8a.

Only one lateral louver 6 is shown in Figs. 17 and 18, but a plurality of transverse louvers 6 are actually installed in a direction perpendicular to the ground of the drawing. Conventionally, each of the lateral louvers 6 has a rotation shaft that is substantially orthogonal to the rotation axis of the longitudinal louvers 7, 8 via the bushing 9 in the support shaft hole 5b provided in the upper wall portion 5a of the air discharge port 5. It is supported to rotate in the transverse direction about the line.

That is, each lateral louver 6 has a support shaft 6a in which a slit 6b is formed in the axial direction and whose radius can be elastically reduced by the slit 6b. After the bushing 9 is fitted into the support shaft hole 5b of 5a, the support shaft 6a is forcibly fitted into the bushing 9 so that each of the lateral louvers 6 is formed on the top of the air discharge port 5. It is rotatably held by the wall part 5a. Moreover, each lateral louver 6 has the connecting pin 6c for attaching the connecting plate 10 to the shoulder part of a wing piece, and is connected so that it may rotate synchronously through the connecting plate 10. As shown in FIG.

According to the operation of the blower fan 4, when air is sucked from the air inlet 2, heat is exchanged in the heat exchanger 3, and then the air is blown from the air outlet 5 toward the room. At this time, the lateral louver 6 Is adjusted to the wind direction in the lateral direction, and is adjusted to the wind direction in the vertical direction by the longitudinal louvers (7, 8).

In this manner, the wind direction is variously controlled, but in the conventional example, since the connecting pin 6c and the connecting plate 10 are exposed in the air discharge port 5, air resistance is generated at that portion, and the wind direction efficiency is improved. In particular, during the cooling operation, dew is generated in the connecting pin 6c and the connecting plate 10, and in extreme cases, dew may be dropped from the air outlet 5 to contaminate the room. have.

In addition, when the lateral louver 6 is reciprocally rotated within a predetermined angle range by a motor, a conventional drive lever 13 as shown in FIG. 19 is conventionally provided separately from the connecting plate 10. At the same time as connecting to (6), one end of the drive lever 13 is connected to a drive shaft of a motor (not shown) via the link arm 14.

As the link arm 14, a link arm having a driving hole 14c coupled to a drive shaft of a motor at one end and provided with a connecting pin 14a at the other end thereof is used, and is driven to the connecting pin 14a. The connecting hole 13a formed at one end of the lever 13 is fitted. In this case, the connecting pin 14a is provided with a head portion 14b having an expanded radius so that the drive lever 13 does not easily come out of the axial direction. Therefore, the slit 13b is formed in the connection hole 13a side of the drive lever 13, and it fits in the connection pin 14a by forcibly expanding the connection hole 13a.

However, according to this connection structure, for example, when the load on the drive lever 13 side becomes heavy, there is a disadvantage that the connection hole 13a is separated from the connection pin 14a via the slit 13b. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the prior art, and its first object is to provide an air conditioner that can easily assemble a horizontal louver without exposing a connecting plate or the like connecting a plurality of horizontal louvers. will be.

A second object of the present invention is to provide an air conditioner having connecting means for reliably connecting a drive lever to a link arm on the motor side when reciprocating a plurality of lateral louvers via a drive lever via a motor.

Advantages according to the present invention will be better understood through the embodiments described below with reference to the accompanying drawings.

First, the first embodiment will be described with reference to FIGS. 1 and 2. Although only a part of the air discharge port 5 of the present air conditioner is shown in FIG. 1, a configuration of another part not shown will be described with reference to FIG. 17 as an example.

Also in the first embodiment, two longitudinal louvers 7 and 8 and a plurality of lateral louvers 6 are provided in the air discharge port 5 in the same manner as in the conventional example described above. In this case, only one lateral louver 6 is shown in FIG. 1, but a plurality of lateral louvers 6 are actually formed in a direction orthogonal to the surface of the drawing. In addition, the support structure of the longitudinal louvers 7 and 8 employ | adopts the structure similar to a prior art example.

Based on the discharge direction of the air discharged from the air discharge port 5 toward the room, the upright position of the upper wall portion 5a of the air discharge port 5 extends vertically toward the inside of the air discharge port 5; One stop piece 51 is provided. Further, at a downstream side of the upper wall portion 5a of the air discharge port 5, a second stop piece 52 vertically extended toward the inside of the air discharge port 5 is provided, and the second stop piece 52 is provided. The stop hole 521 is provided in this.

The cover plate 11 is supported by the first stop piece 51 and the second stop piece 52 so that a predetermined space is formed between the upper wall portion 5a of the air discharge port 5. In the first embodiment, the cover plate 11 has a branched stop portion 11b having a V or U shape which is joined to the edge of the first stop piece 51 at its rear wall portion. On the front end side, a flange 11d having a projection 11c is formed.

That is, the cover plate 11 engages the stop portion 11b at the rear end thereof with the end edge of the first stop piece 51, and presses the flange 11d at the front end along the second stop piece 52. It is held between the first stop piece 51 and the second stop piece 52 by a simple operation of coupling the protrusion 11c to the stop hole 521.

The cover plate 11 is provided with a plurality of penetrating holes 11a corresponding to the respective transverse louvers 6, and each of the transverse louvers 6 is rotatable to the penetrating holes 11a via the bush 9A. Supported.

As shown in FIG. 2, the support shaft 6a is provided at the upper edge of the lateral louver 6. This support shaft 6a has an arrowhead-shaped head portion, and slits 6b are formed along the axis line from the center of the head portion. By the slit 6b, the radius of the support shaft 6a can be elastically reduced.

The bush 9A has a base end 91 having a shaft hole 90 to which the support shaft 6a is coupled, and an arm 92 connected to be perpendicular to an axis of the shaft hole 90 from an upper edge of the base end 91. Equipped with. The proximal end 91 has a cylindrical shape rotatably coupled into the penetrating hole 11a of the cover plate 11, and a flange 93 having a diameter larger than that of the penetrating hole 11a is formed at the upper edge thereof. Further, in the shaft hole 90 and the support shaft 6a, a flat portion for transmitting the rotation of the bush 9A to the lateral louver 6 is formed.

The arm 92 extends from the flange 93, and an edge pin 94 is provided at its distal end for attaching the connecting plate 10. As shown in FIG. The connecting plate 10 is provided with a plurality of connecting holes 10a having a predetermined interval, that is, an interval substantially equal to the interval of arrangement of the lateral louvers 6. The connecting pin 94 is a cylindrical pin having a head portion larger in diameter than the connecting hole 10a, and a slit 94a is formed along the axis line from the center of the head portion. By this slit 94a, the radius of the connecting pin 94 can be elastically reduced.

In assembling, first, the proximal end 91 of the bush 9A is inserted from above into the through holes 11a of the cover plate 11. Subsequently, while lowering the radius of the support shaft 6a of each lateral louver 6 from below the cover plate 11, it forcibly engages in the shaft hole 90 of the bush 9A, and the head part of the shaft hole 90 Protrude upwards. Accordingly, the lateral louvers 6 are held by the cover plate 11 via the bush 9A without falling off. Next, the connecting hole 10a of the connecting plate 10 is forcibly coupled to the connecting pin 94 of the arm 92, and the connecting plate 10 is attached to the bush 9A. On the contrary, the connecting plate 10 may be attached to the bush 9A, and then the lateral louver 6 may be attached to the bush 9A.

In this manner, the plurality of transverse louvers 6 are attached to the cover plate 11. Then, the cover plate 11 is attached between the first stop piece 51 and the second stop piece 52 in the above order.

Accordingly, since the cover plate 11 substantially forms the upper wall portion of the air discharge port 5 and covers the connecting plate 10 and the connecting pin 94, the air blowing efficiency is lowered or noise is generated as in the prior art. Or dew does not occur.

Next, a second embodiment shown in FIGS. 3 to 10 will be described. First, the cover plate 11 differs from the first embodiment in that the grip portion 53 is integrally formed at the lower end of the second stop piece 52. The gripping portion 53 extends to the front surface (front) of the air discharge port 5 so as to be easily operated by a finger, and the gripping portion 53 moves in the direction of the arrow shown in the drawing view of FIG. By lifting, the coupling | bonding of the stop hole 521 and the protrusion 11C can be performed simply. Therefore, the maintenance operation is convenient to carry out.

Also in the second embodiment, the lateral louvers 6 are interconnected to rotate synchronously by the connecting plate 10, but as shown in FIG. 4, in addition to the motor 12 as a driving means. As a result, a configuration is adopted in which the lateral louvers 6 rotate reciprocally within a predetermined angle range via the driving lever 13.

For this reason, as shown in FIG. 5, the hemispherical protrusion 95 as a coupling means with respect to the drive lever 13 is formed in the upper surface of the arm 92 of the bush 9B. On the contrary, as shown in FIG. 6, an initial angle setting means 132 is provided on the lower end side of the driving lever 13 in which a plurality of grooves 131 are continuously installed in waveform. That is, by engaging the projection 95 to any one of the grooves 131 in the initial angle setting means 132, the initial angle of the lateral louver 6 can be set.

In order to couple the protrusion 95 and the groove 131 with an appropriate friction force, a gate-shaped holding frame 96 into which the driving lever 13 is inserted is formed on the upper surface of the arm 92. Moreover, the said holding frame 96 is provided with the processus | protrusion 96a which attaches the drive lever 13 to the processus | protrusion 95 side.

At the lower end side of the arm 92 of the bush 9B, a connecting pin 97 is engaged with the connecting hole 10a of the connecting plate 10. A holding piece 98 is also provided on the lower surface side of the arm 92 to hold the coupling pin 97 coupled to the coupling hole 10a. In the present embodiment, the holding piece 98 is bent almost 180 degrees from the tip of the arm 92, and the gap between the holding piece 98 and the lower surface of the arm 92 is the plate thickness of the connecting plate 10. It is almost the same thickness as.

Further, according to the second embodiment, the stopper 99 which restricts the rotation range of the lateral louver 6 protrudes downward near the base end 91 of the lower surface of the arm 92. In contrast, as shown in FIG. 7, a pair of regulating pieces 10b and 10b adjacent to the stopper 99 are provided on the connecting plate 10 side when the connecting plate 10 moves a predetermined amount. That is, the amount of movement of the connecting plate 10 in the right direction, for example, is regulated by one regulating piece 10b, and the amount of movement in the left direction is regulated by the other regulating piece 10b.

The drive lever 13 is connected to the bush 9B by inserting the door-shaped retaining frame 96 provided on the upper surface of the arm 92 (see Fig. 6). By connecting the connecting hole 10a to the connecting pin 97 in the state in which the holding piece 98 is rolled, it is connected to the bush 9B (refer FIG. 7).

In the second embodiment, as shown in Fig. 4, the plural lateral louvers 6 are divided into two groups from their nearly centers, whereby the connecting plates 10 are assigned to each group. On the other hand, the drive lever 13 has only one, and the initial angle setting means 13a is provided in the position corresponding to any one horizontal louver 6 in each group.

That is, since the lateral louvers 6 in each group are connected by the respective connecting plates 10, the driving force for rotating the lateral louvers 6 by the drive lever 13 is one of the lateral louvers in the group. 6), the driving force is transmitted to the other transverse louver 6 via the connecting plate 10. As shown in FIG.

In addition, since the drive lever 13, the connecting plate 10, and the like can be attached to the bush 9B, the base end 91 and the arm (in order to reduce the frictional resistance of the bush 9B) can be attached. It is preferable that it is formed integrally with synthetic resins, such as polyacetal resin, which contains each part, such as 92), and has elasticity and contains a wax component as a lubricant.

In the second embodiment, the drive lever 13 is connected to the motor 12 via the link arm 14A shown in FIG. When explaining the connection structure, the connection hole 133 is provided at one end of the drive lever 13, and the tongue piece 134 which protrudes partially is provided at the end. In this case, the extending projection direction of the tongue piece 134 becomes a direction orthogonal to the longitudinal direction of the drive lever 13.

At one end of the link arm 14A, a drive hole 141 is formed to engage the drive shaft 12a (see Fig. 4) of the drive motor 12. On the other end side of the link arm 14A, a connecting pin 142 is coupled to the connecting hole 133 of the drive lever 13 and a receiving groove 143 into which the tongue piece 134 of the drive lever 13 can be inserted. have.

As shown in FIGS. 9A and 9B, the driving lever 13 and the link arm 14A are coupled to the connecting hole 133 with respect to the connecting pin 142 in a state in which their longitudinal directions coincide with each other. When the driving lever 13 and the link arm 14A are rotated relatively by a predetermined angle, the tongue piece 134 is inserted into the receiving groove 143. Therefore, within the predetermined angle range in which the tongue piece 134 is inserted into the receiving groove 143, the connecting pin 142 and the connection hole 133 do not deviate in the axial direction.

Specifically, as described above, after connecting the drive lever 13 and the link arm 14A in their longitudinally aligned state, the link arm 14A is attached to the drive lever 13 to the tongue piece 134. In the state rotated 90 degrees to the side, as shown in FIG. 10A, the link arm 14A is attached to the drive shaft 12a of the drive motor 12.

With this state in the neutral position, the link arm 14A is driven reciprocally between the right limit position shown in FIG. 10B and the left limit position shown in FIG. 10C by the motor 12, but the tongue piece 134 By designing the size of the opening angle of φ not to be separated from the accommodation groove 143 within the rotation range, it is possible to reliably prevent the drive lever 13 from falling off from the link arm 14A.

Next, a third embodiment will be described. In the third embodiment, as shown in Fig. 11, in supporting the cover plate 11, the first stop piece 51a is moved upward from the upstream position of the upper wall portion 5a of the air discharge port 5; And the one end 111 side of the cover plate 11 is installed along the first stopper 51a so as to substantially constitute a part of the air discharge port 5, and the first end of the cover plate 11 A raised stop step portion 112 is formed to engage with the end of the stop piece 51a.

Further, in the downstream position of the upper wall portion 5a of the air discharge port 5, the second stop piece 52 having the stop hole 521 is vertically extended in the same manner as in the above embodiments, but in the third embodiment The female thread hole 114 is formed in the other end 113 of the cover plate 11 corresponding to the 2nd stop piece 52, and the female thread hole is received from the stop hole 521 of the 2nd stop piece 52. As shown in FIG. The male screw 115 is screwed to 114 to screw the other end 13 of the cover plate 11 to the second stopper 52.

Also in the third embodiment, the stop step 112 at the one end 111 side of the cover plate 11 is screwed to the end of the first stop piece 51, and the other end of the cover plate 11 is closed. By screwing the 113 to the second stopper 52, the cover plate 11 can be attached so as to create a predetermined space between the upper wall portion 5a of the air discharge port 5.

As shown in FIG. 11, in the third embodiment, the lower wall portion 5c of the air discharge port 5 is integrally formed with the cover plate 11 via the support plate 116. As shown in FIG. Although only one support plate 116 is shown in FIG. 11, a plurality of support plates 116 are formed at predetermined intervals between the support plates 16 in the width direction of the air discharge port 5 perpendicular to the ground of the drawing. Therefore, not only the cover plate 11 but also the lower wall portion 5c of the air discharge port 5 is detachable from the air discharge port 5, and when attached to the air discharge port 5, the rear end of the lower wall portion 5c It is fixed to the frame member 1a by the screw 117 in the housing 1.
