Description

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 blind plate detachably attached to a lower corner portion of a housing.

[0002]

2. Description of the Related Art In a conventional air conditioner indoor unit, as shown in FIG. 3A, a front panel 10 is detachably attached to a front portion of a housing 1, and a locking portion 3a is attached to a lower corner portion. 3b,
3c is provided, and a blind plate 2 having a substantially L-shaped cross section for connection work such as a power cable is detachably locked. Specifically, the blind plate 2 is, as shown in FIG.
Locking portions 3a, 3b, 3 provided with one on a and two on the side surface 1b
The claws 4a, 4b, 4c provided on the blind plate 2 corresponding to the locking portions 3a, 3b, 3c were locked and fixed to c. Therefore, when connecting the power cable etc., first
Grasp the bottom surface of the blind plate 2 by hand and pull it downward to remove the claw 4a that engages with the engaging portion 3a of the bottom surface 1a of the housing 1, and then remove the blind plate 2 from the side surface 1b of the housing 1. The engaging portion 3b, the engaging portion 3c as a fulcrum, and the engaging portion 3b that pivots to the outside of the side surface 1b of the housing 1 to engage with the side surface 1b of the housing 1, the pawl 4b that engages with the engaging portion 3c, and the pawl. I was trying to remove 4c.

However, in this structure, the indoor unit of the air conditioner is provided with the blind plate 2 and the side surface 1b of the housing 1 is provided with the wall 4.
When the blind plate 2 is installed close to the side wall without any gap, the blind plate 2 hits the wall even if the blind plate 2 is pivoted to the outside of the side surface 1b of the housing 1 with the locking portions 3b and 3c of the side surface 1b as fulcrums. Since the blind plate 2 cannot be removed because it cannot be moved, there is a problem that connection work such as a power cable cannot be performed.

[0004]

SUMMARY OF THE INVENTION The present invention solves the problems described above, and even when the indoor unit of the air conditioner is installed on the side surface on the side where the blind plate is provided without a gap in the wall, the blind It is an object of the present invention to provide an indoor unit of an air conditioner that can be connected to a power cable or the like by removing the plate.

[0005]

In order to solve the above-mentioned problems, the present invention has a front panel detachably attached to a front portion of a housing, a lower corner portion is provided with a locking portion, and the locking portion is attached to the locking portion. In an indoor unit of an air conditioner, in which a blind plate having a corresponding claw and having a substantially L-shaped cross section is detachably locked, the blind plate is rotated between a lower inner side portion of the housing and the blind plate. A rotating means for freely supporting the shaft is provided, and the claw is disengaged from the engaging portion by rotating the blind plate forward and backward of the housing.

Then, the rotating means is formed by a support shaft provided on the inside of the side surface corner of the housing and a bearing provided on the blind plate, or provided on the inside of the side surface corner of the housing. The bearing is provided with a support shaft provided on the blind plate. Also, the support shaft is formed in a hemispherical shape,
The support shaft provided inside the side surface corner of the casing is formed of an elastic material into a cylindrical shape. Further, the bearing has an inner surface formed into a spherical surface, or the bearing provided on the blind plate is formed into a shaft hole.

[0007]

With the above construction, in the indoor unit of the air conditioner of the present invention, the blind plate is rotatably pivoted by the turning means provided on the inner side lower end of the housing and the blind plate. Since it is supported, after removing the front panel, the blind plate can be pivoted back and forth in the housing to remove the claw from the locking portion.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an indoor unit of an air conditioner according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a side perspective view of a main part of an indoor unit of an air conditioner. As shown in the figure, an indoor unit of an air conditioner according to the present invention includes a housing 1
The front panel 10 is detachably arranged at the front part of the housing 1, the locking portion 3a provided on the bottom surface of the lower corner portion of the housing 1, the locking portion 3b provided on the side surface, the locking portion 3a, the locking portion 3b. Correspondingly, a blind plate 2 having a claw 4a and a claw 4b and having a substantially L-shaped cross section is detachably locked, and the blind plate is attached to the inner side portion of the lower end of the housing 1 and the blind plate 2. Rotation means for rotatably supporting 2 is provided.

FIG. 2 is an enlarged perspective view of a rotating means in which the blind plate 2 is rotatably supported by the inner side portion of the side surface 1b of the casing 1 and the blind plate 2. In the embodiment of FIG. 2-a, a hemispherical protruding shaft 5a is provided on the inside of the side surface 1b corner of the housing 1,
The blind plate 2 is provided with a shaft supporting portion 6 having a shaft hole 6a.

Further, in the embodiment shown in FIG.
A hemispherical shaft hole 5b is provided on the inner side of the side corner, and the blind support 2 is provided with a shaft support 6 having a hemispherical protruding shaft 6b.

In the embodiment shown in FIGS. 2-a and 2-b, the protruding shaft 5a and the protruding shaft 6b are formed in a hemispherical shape, but the tip portion is formed in a hemispherical cylindrical shape using an elastic material. It is needless to say that the same effect can be obtained by doing so.

Next, a procedure for removing the blind plate 2 from the corner portion of the housing 1 in the above configuration will be described. First, after removing the front panel 10 arranged on the front part of the housing 1, the lower part of the blind plate 2 is grasped by hand and pulled downward strongly as in the conventional case, and the locking portion on the bottom surface of the housing 1 is held. 3a to the nail 4 of the blind plate 2
Remove a. Next, by pulling the blind plate 2 toward you, the blind plate 2 is rotated about the shaft support portion, and the locking portion 3b on the side surface of the housing 1 is rotated.
The claw 4b of the blind plate 2 can be removed from here. Finally, the blind plate 2 can be removed from the housing by pulling the blind plate 2 in the lateral direction and removing the shaft supporting portion.

[0013]

As described above, according to the indoor unit of the air conditioner of the present invention, the blind plate can be freely rotated by the inner side lower end of the housing and the rotating means provided on the blind plate. Since the blind plate is pivotally supported and the pawl is removed from the locking portion by rotating the blind plate in the front or rear direction of the housing, the indoor unit of the air conditioner is provided with the blind plate on the side surface. It is possible to provide an indoor unit of an air conditioner in which the blind plate can be removed and connection work such as a power cable can be performed even when the unit is installed on a wall without a gap.
