DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit constituting an air conditioner, and more particularly to an improvement in a louver structure provided at an outlet of a ventilation path.

[0002]

2. Description of the Related Art An air conditioner generally used comprises an indoor unit arranged in a room to be air-conditioned and an outdoor unit arranged outdoors, and these units are connected to each other by a refrigerant pipe and electric wiring. .

[0003] In particular, in an indoor unit, an indoor heat exchanger and a blower are arranged in a unit body having a suction port and a blowout port, and a ventilation path is formed between the blower and the blowout port.

[0004] Then, the blower is operated together with the refrigeration cycle operation for the indoor heat exchanger, and the air to be conditioned is sucked into the unit body from the suction port and guided to the indoor heat exchanger.
After the heat exchange, the air is blown from the outlet to the room to be air-conditioned through the ventilation path.

[0005] In such an indoor unit, a louver for changing the wind direction of the heat exchange air blown out from the outlet is provided particularly at the outlet. This louver is usually composed of a combination of a vertical louver for changing the wind direction in the left-right direction from the unit body and a horizontal louver for changing the wind direction in the vertical direction.

[0006]

A filter is removably mounted between the suction port and the heat exchanger to filter the air to be conditioned in the unit to be sucked into the unit body. The user needs to remove the filter appropriately to remove the captured dust.

[0007] Therefore, originally, inside the unit body,
Dust does not adhere to the heat exchanger and blower,
There is a drop in the filtration capacity of the above filter, or there is dust that enters the unit body from the suction port and air outlet during the stop period, and dust adheres to the heat exchanger and the blower over a long period of use, Easy to stack.

Therefore, it is necessary to perform a maintenance operation for periodically cleaning the inside of the unit body. If it is a recent indoor unit, the front panel equipped with a grill facing the suction port is detachably or rotatably attached to the unit main body, so that the heat exchanger can be relatively easily exposed, The dust attached here can be removed.

However, since the blower is disposed on the back side of the heat exchanger, the blower is not exposed unless the heat exchanger is removed. To remove the heat exchanger,
The refrigerant pipe connected here must also be removed,
It is virtually impossible.

On the other hand, since the blower is located at the end of the ventilation path, if a hand enters from the outlet, the blower can come into contact with the blower through the ventilation path, and the dust can be removed. However, the outlet is provided with a horizontal louver and a vertical louver, and the gap formed between each louver is very small, and it is practically impossible to clean the blower from this gap.

However, in the case of a horizontal louver, at most 2
Since the number of pins is only about one and the pins projecting from both side ends are pivotally supported by the pivot holes formed in the side surfaces of the ventilation passage, it does not require much labor for removal.

On the other hand, the vertical louvers are composed of a far larger number of sheets than the horizontal louvers, and the upper and lower ends of the vertical louvers are pivotally supported by pivot holes formed in the upper and lower surfaces of the ventilation passage. Therefore, removal is almost impossible.

Further, the louver base 16 is provided with a hole 22 formed of a long hole in the lateral direction near the other side edge and substantially at the center. Angle control projections 23 are integrally provided on the vertical louver 17 pivotal support portions on both left and right sides.

As shown in FIG. 6, the vertical louvers 17 on both the left and right sides are provided with base end portions 17 which slide on the surface of the louver base 16.
a is formed into a half circle of a small radius and a half circle of a large radius,
These boundaries are steps.

On the other hand, the angle regulating projection 23 provided integrally on the surface of the louver base 16 is formed in an arc shape. The radius of curvature on the inner diameter side is the vertical louver base end 17.
a is the same as the small radius, and the radius of curvature on the outer diameter side is the same as the large radius.

When the vertical louver 17 is in a direction perpendicular to the longitudinal direction of the louver base 16 as shown in FIG. 4B, both ends of the angle regulating projection 23 are on both sides of the base end 17a. It is set so as to have an equal interval with the step.

As shown in FIGS. 3 and 4, the vertical louver 17 is integrally provided with a connecting rod portion 17b parallel to the surface direction of the louver base 16. This connecting rod 1
7b is the hinge 1 referred to as a so-called PP hinge.

Therefore, the louver base 16 has the same configuration as the parallel link mechanism with all the vertical louvers 17 (including the connecting rod 17a) and the wind direction guide 19.
A knob 19a is integrally provided substantially at the center of the wind direction setting section 19, and by moving the wind direction guide section 19 along the longitudinal direction with the knob 19a, the vertical louvers 17 are moved in the same direction. They can be turned at the same time and set at the same angle.

On the wall surface of the ventilation passage 13 to which such a louver unit 15 is mounted, a concave portion 24 having the same shape area as the length (L) of the auxiliary claw 21 larger than the louver base 16 is formed. ing. Above recess 2
The concave depth of 4 corresponds to the thickness of the louver base 16.

A plurality of (four in this example) locking windows 25 are provided in the recess 24 at predetermined intervals along the longitudinal direction.
Is opened. In these hooking windows 25, a portion having a long width and a portion having a short width are provided continuously, and have a stepped rectangular shape.

At the center in the longitudinal direction of the recess 24, a projection 26 is provided integrally. The protrusion 26 has a protrusion height dimension equal to the thickness of the louver base 16 and has an area shape capable of being inserted into the hole 22 provided in the louver base.

A pair of slits 27 are provided on both sides of the projection 26, and the projection 26 is pushed up and urged to form the slit 2 together with the projection 26.
The portion between 7, 27 is easily elastically deformed.

Further, rectangular or round through holes 28 are provided between the above-mentioned engaging windows 25 and between the engaging windows 25 and the projections 26. With the louver base 16 attached to the recess 24,
A boss portion 16a that pivotally supports the vertical louver 17 at a position that does not face the locking window portion 25 is located.

In particular, as shown in FIG. 5, a detection switch 29, which is a microswitch, is provided at a position corresponding to the back side of the projection 26. This detection switch 29
Is electrically connected to a control circuit 30 for controlling the operation of the fan motor 7M constituting the blower 7.

While the detection switch 29 is off, there is no relation between the operation and the stop of the fan motor 7M.
In the ON state, a signal for cutting off the power supply to the fan motor 7M is set even when the blower is operating.

Thus, the indoor blower 7 is driven with the refrigeration cycle operation, and the front and upper suction ports 5a, 5b
The air to be conditioned is sucked into the unit main body 1 from the inside. Then, heat exchange is performed by flowing through the front heat exchanger 5a, and heat exchange is performed by flowing through the auxiliary heat exchanger 6B and the rear heat exchanger 5b.

The air that has exchanged heat with these heat exchangers 5a, 5b, 6B is guided from the blower 7 to the ventilation passage 13, where the air direction is set by the air direction changing device R, and the outlet 11
Air from the room to be conditioned.

By adjusting the wind direction changing device R, it is possible to change the blowing direction of the heat exchange air blown from the blowing port 11. That is, when adjusting the blowing direction from the blowing port 11 in the vertical direction, the horizontal louvers 14 and 14 are respectively rotationally displaced. In the case where the adjustment is made in the left-right direction, the knobs 19a of the vertical louver unit 15 are slid and displaced, so that the vertical louvers 17 are simultaneously turned in the same direction.

As shown in FIG. 6, the maximum angle of the vertical louver 17 is restricted. As shown in FIG. 3A, when the wind direction setting section 19 is moved leftward in the figure, the vertical louver 17 is rotated clockwise and can be set in the same direction. .

When the wind direction setting portion 19 is further moved in the same direction, one of the steps formed on the base end portion 17a of the vertical louver 17 finally comes into contact with one of the angle regulating projections 23 on the side end portion. In contact therewith, further rotation is restricted. That is,
This is the maximum wind direction change angle of the vertical louver 17.

When the wind direction setting section 19 is moved rightward in the figure from the state shown in FIG. 7A, the vertical louver 17 rotates clockwise, and as shown in FIG. Wind direction change angle becomes zero.

When the movement in the same direction is further performed, the other step of the vertical louver base end 17a finally comes into contact with the other side end of the angle regulating projection 23 as shown in FIG. In contact therewith, further rotation is regulated, and the maximum louver 17 has the maximum wind direction change angle.

Since the angle restricting projections 23 are integrally formed on the louver base 16, the mold structure is simpler and can be easily formed as compared with the case where the projections are provided in the ventilation passage 13.

When the fan is used for a long period of time, dust adheres particularly to the cross flow fan constituting the blower 17. If left as it is, the dust may be mixed with the heat exchange air and blown out. Therefore, the dust must be removed as necessary.

At this time, the horizontal louver 14 and the vertical louver unit 15 are removed. When removing the vertical louver unit 15, the protrusion 26 inserted into the hole 22 of the louver base 16 is pushed up to release the protrusion 26 from the hole 22 and slide the louver base 16 toward the claw 20. Then, the hook 20b of the hook 20 is elastically deformed, the louver base auxiliary hook 21 is removed from the hook of the hook window 25, and the louver base 16 is inclined.

Further, the locking window 2 of the ventilation passage recess 24 is provided.
When the hook of the louver base claw portion 20 is released from 5, the vertical louver unit 15 is removed. That is, the vertical louver unit 15 can be easily removed from the ventilation path 13. In this state, since the cross flow fan of the blower 7 is exposed from the outlet 11, dust can be easily removed.

When the vertical louver unit 15 is removed, the detection switch 29 arranged on the rear surface side of the vertical louver unit 15 is turned on while the projection 26 is pushed up. A stop signal is sent from the detection switch 29 to the blower 7 via the control circuit 30, and the energization is cut off.

Therefore, even if the maintenance work is performed during the air-conditioning operation and the vertical louver unit 15 is removed, the operation of the blower 7 is automatically stopped, so that safety is ensured.

After the necessary maintenance work is completed, the vertical louver unit 15 is attached to the air passage recess 24 again. Contrary to the removal work, the louver base claw 20 is hooked on the side of the recessed portion hooking window 25 and the louver base 1
6 into the recess 24, and the louver base auxiliary pawl 2
1 may be hooked on the side of the hooking window 25.

In this way, the hook 20 of the hook 20
Due to the elasticity of b, the louver base 16 is pushed in the direction of the protrusion 26, and the hole 22 is inevitably hooked on the protrusion 26, so that the attachment work can be easily performed as in the removal work of the vertical louver unit 15. Becomes

Since the height of the projection 26 is set to be the same as the thickness of the louver base 16, the tip of the projection 26 is flush with the plate of the louver base 16.
From this, the presence of the projection 26 cannot be confirmed unless it is intentionally contacted. That is, as long as the vertical louver unit 15 is not intentionally contacted with the projection 26 for removal, the contact with the projection 26 by mistake is prevented.
