DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner, and more particularly, to an air conditioner having a fan guard attached to an outlet of the indoor unit.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 1, an indoor unit of an air conditioner is provided with a suction port 2 for sucking indoor air at an upper front portion and / or an upper surface of a main body of the indoor unit 1, and a lower front portion of the indoor unit 1. An outlet 4 for blowing out the air heat exchanged by the heat exchanger 3 is provided, and a heat exchanger 3 and a blower fan 5 are provided in an air passage connecting the inlet 2 and the outlet 4. A plurality of upper and lower wind direction plates 7 and left and right wind direction plates 6 for blowing the heat-exchanged air in a designated direction before and after the air outlet 4.
These are rotatably supported by a blower casing 8 constituting the outlet 4.

FIG. 4 shows the left and right wind direction plates 6 of a blower casing 8.
FIG. 3 is a perspective view of the guard wire 80 attached to the arm. The upper and lower wind direction plates are not shown. The blower casing 8 is made of plastic, and has a shape in which side walls 81 provided on the left and right sides are joined by an upper wall 82 and a lower wall 83 that are parallel to each other with a space therebetween, and blows air between the upper and lower walls. It has a structure. The upper and lower walls are connected by a support column 84 that supports an upper and lower wind direction plate (not shown). A plurality of left and right wind direction plates 6 are disposed between the upper and lower walls, and the upper end of each left and right wind direction plate 6 faces upward. It is rotatably supported by the wall 82. Furthermore, in order to insert two pairs of guard wires 80 for protecting a finger or the like from touching the blower fan, four insertion holes are provided on the side surfaces of the left and right wind direction plates 6, the support columns 84, and the side walls 81. The end of the guard wire 80 bent into a U-shape is inserted from the insertion hole of one of the side walls 81 into the left and right wind direction plates 6, the support 84, and the other side wall 81, respectively. The inserted guard wire 80 is bent at its end so as not to fall off, or a fixing plate 85 for fixing the U-shaped end by pressing it against the side wall 81 is fixed by a screw 86.

However, it takes time and effort to bend the end of the inserted guard wire so that it does not fall off. Further, since two guard wires can be inserted at a time, all the guard wires are inserted. Therefore, it is necessary to perform the same work a plurality of times, which increases the number of man-hours and increases the cost.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a guard wire mounting structure for an air conditioner according to the present invention. Since the structure of the air conditioner has been described in the conventional embodiment, the description is omitted here. FIG. 2 is a perspective view of a blower casing provided with a first embodiment of a guard wire of an air conditioner according to the present invention. The blower casing 10 is made of plastic and has side walls 1 provided on the left and right.
1 are joined by an upper wall 12 and a lower wall 13 which are spaced apart from each other and are parallel in the horizontal direction, and a structure in which air is blown from between the upper and lower walls. The upper and lower walls are connected by a support 14 for supporting a vertical wind panel (not shown), and a plurality of left and right wind panels 15 are disposed between the upper and lower walls. It is rotatably supported by the wall 12. Furthermore, in order to insert five guard wires 16 of the same length for protecting a finger or the like from touching the blower fan, the guard wires 16 are provided in the left and right wind direction plates 15, the struts 14, the side walls 11, and the blower casing 10. Five insertion holes 17 are provided on the side surface of the second side wall 20. One end of the guard wire 16 is fixed to a pressing plate 18 that connects the guard wires 16 in parallel, and the other end of the guard wire 16 is inserted through the insertion hole 19 in one side wall 11 into the left and right wind direction plates 15. , The support 14, and the second side wall 20.

Since the five guard wires 16 are connected and fixed to the holding plate 18, the left and right wind direction plates 1
5, five insertion holes 1 provided in side wall 11 and pillar 14
7, a plurality of guard wires 16 can be inserted at the same time, so that the number of assembly steps can be reduced and the cost can be reduced. Further, a motor 21 for reciprocatingly rotating the vertical wind direction plate and a drive unit 22 containing a reduction gear and the like
The cover and the one side wall 11 have a structure in which the holding plate 18 is sandwiched and fixed with the screws 23, so that the holding plate 18 does not need to be fixed alone, and a fixing component for fixing alone is used. Fixed work can be reduced.

FIG. 3 is a sectional view showing another embodiment of the guard wire of the air conditioner according to the present invention, wherein (A) is a second embodiment, (B) is a third embodiment, and (C). Shows a fourth embodiment. First, a second embodiment will be described with reference to FIG. The guard wire 30 is five rods made of steel having the same length. One end of the guard wire 30 is aligned with and fixed to a cylindrical boss 32 provided on a holding plate 31.
In addition, an inverted U-shaped locking claw 33 is provided at both ends of the holding plate 31.
An engagement claw 34 that fits in correspondence therewith is erected from a side wall 35 of the blower casing. The other end of the guard wire 30 is inserted through the insertion hole 36 of the side wall 35 through the insertion holes provided in the left and right wind direction plates and the columns (both not shown), and finally into the second side wall 37 of the ventilation casing. I do. When the guard wire 30 is inserted until the holding plate 31 and the side wall 35 abut, the locking claw 33 and the engaging claw 34 are fitted, and the guard wire 30 is fixed to the side wall 35. By providing the locking claws 33 and the engaging claws 34 in this manner, the guard wire 30 can be inserted and fixed at the same time, so that the number of assembly steps can be reduced.

Next, a third embodiment will be described with reference to FIG. The guard wires 40 are five rods made of steel having different lengths, and one end thereof is aligned and embedded and fixed in a cylindrical boss 42 provided on the holding plate 41. In this manner, by making the lengths of the distal ends of the guard wires 40 intentionally different, for example, five guard wires 40 are inserted into five insertion holes provided in one left and right wind direction plate (not shown). When each is inserted, since it can be inserted one by one from the longest guard wire 40,
Insertion work can be performed easily.

Further, a fourth embodiment will be described with reference to FIG. The guard wire 50 is composed of five rods made of steel having the same length. One end of the guard wire 50 is slightly shifted in the length direction, and is embedded in a cylindrical boss 52 provided on the holding plate 51. Fixed. Therefore, the other end of the guard wire 50 has a slightly different length. Therefore, for example, when five guard wires 50 are respectively inserted into five insertion holes provided in one left and right wind direction plate (not shown), one can be inserted one by one from the longest guard wire 50. , Insertion work can be easily performed. Also, since the guard wires 50 have the same length, parts can be shared, and the cost of parts can be reduced as compared with the embodiment of FIG. 3B.

Further, a cylindrical boss 54 projecting from the holding plate 51 in the direction of the side wall 53 and surrounding the guard wire 50 is provided, and an insertion hole 55 of the side wall 53 for inserting the guard wire 50 is fitted with the boss 54. When the holding plate 51 abuts on the side wall 53, the two can be positioned at a predetermined position.
For this reason, the locking claw 56 and the engaging claw 57 having the same structure as the locking claw 33 and the engaging claw 34 described in the second embodiment can be accurately fitted to each other to prevent unintended dropping. it can.
Note that the positioning boss and the insertion hole are not limited to this embodiment, and may be provided in any position of the holding plate and the side wall in combination with each other.

[0021]
