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 a guard wire attachment holder for preventing fingers from being inserted.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 4, an indoor unit of an air conditioner is arranged in parallel behind a blowout port 1 of the indoor unit, and a plurality of blown winds are deflected to the left and right. The left and right wind direction plates 2 and the up and down wind direction plates 4 that deflect the blown air in the up and down direction are provided in front of the left and right wind direction plates 2, and each of the left and right wind direction plates 2 is provided with a plurality of insertion holes 3. The guard wire 5 for preventing fingers from being inserted is inserted into the insertion hole 3, the both ends of the guard wire 5 are bent, and the bent portions 5a are fixed to the protrusions 7a of the holder 7 fixed to both sides of the outlet 1. Provided locking hole 7
It was locked and fixed to b. However, as shown in FIG. 5, a space for accommodating a drain hose or the like on one side of one of the holders 7 closes a part of the air outlet 1, and a space for arranging a vertical wind direction plate on the front surface of the room. 8 is formed,
A part of the blowing air deflected in the left-right direction by the left-right airflow direction plate 2 entrains warm room air in the space portion 8, and dew is attached to the cold holder 7 or the like that has been in contact with the entrained warm air. There was a problem that this dew was blown into the room by being blown by the blowing air.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems and prevents the warm indoor air entrained from touching the holder, thereby exposing the guard wire provided at the outlet to the holder. It is an object of the present invention to provide an indoor unit for an air conditioner that reliably prevents sticking.

[0004]

In order to solve the above-mentioned problems, the present invention provides a plurality of left and right airflow direction vanes for deflecting blown air in the left and right direction, and a front part of the left and right airflow direction vanes behind the air outlet of the indoor unit. Is equipped with a vertical wind direction plate that deflects the blowing air in the vertical direction,
A guard wire for preventing fingers from being inserted through a plurality of insertion holes provided in the left and right wind direction plates, and bent portions at both ends of the guard wire are formed on protrusions of a holder fixed to both sides of the air outlet. In an indoor unit of an air conditioner that is locked and fixed in a stop hole, a ventilation hole is provided between the protrusions of the holder, and blown air is ventilated on the back surface of the holder to thereby retain the holder. Prevents exposure to Also,
The ventilation hole is formed from the inside of the protrusion. Also,
The ventilation hole is a long hole or a U-shaped cutout groove from the outside of the holder.

[0005]

Since the air conditioner indoor unit of the present invention is provided with the ventilation holes between the protrusions of the holder, the left and right wind direction plates deflect the left and right directions. Since a part of the blown out air is ventilated to the back surface of the holder, the warm indoor air trapped in the space does not touch the back surface of the holder, and it is possible to prevent dew condensation on the holder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An indoor unit of an air conditioner according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a side sectional view of an essential part showing an indoor unit of an air conditioner according to the present invention. Since this figure has been described in the section of the prior art, description thereof will be omitted. 2A and 2B are views showing the vicinity of the holder 7 provided in the air outlet 1 of the indoor unit of the air conditioner according to the present invention, FIG. 2A being a front view, FIG. 2B being a sectional view taken along line AA in FIG. 8A] is a sectional view taken along line AA showing another embodiment. As shown in the figure, a long hole 7c1 or a ventilation hole 7c which is a U-shaped cutout groove 7c2 from the outside of the holder 7 is provided between the protrusions 7a of the holder 7 fixed to the outlet 1.

The operation of the above arrangement will be described below. FIG. 3 is an explanatory diagram for explaining the operation. As shown in the drawing, a part of the blown air deflected in the left-right direction by the left-right airflow direction plate 2 is ventilated to the back surface of the holder 7 through the ventilation holes 7c provided between the protrusions 7a of the holder 7. Therefore, the warm indoor air that is entrained by the blowing air does not touch the back surface of the holder 7, and the dew on the holder 7 and the like is prevented.

[0008]

As described above, according to the indoor unit of the air conditioner according to the present invention, since the ventilation holes are provided between the protrusions of the holder, the blowouts deflected in the left and right directions by the left and right wind direction plates are provided. Since a part of the wind is ventilated to the back side of the holder, the warm indoor air entrained in the space does not touch the back side of the holder, and the entrained warm room air does not touch the holder, so It is possible to provide an indoor unit of an air conditioner that reliably prevents the provided guard wire from being exposed to the holder.
