Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner equipped with an indicator for displaying various functions.

[0002]

2. Description of the Related Art Various indicators are incorporated in the front panel of an air conditioner. For example, this display is composed of a plurality of LEDs, and each LED displays a display item such as an operating state or a defrosting state.

A plurality of LEDs are mounted on a flat substrate, the substrate is mounted on the front side of the indoor unit of the air conditioner, and the LEDs are arranged in the vertical direction of the indoor unit. A cover is arranged in the indoor unit of the air conditioner in correspondence with this indicator.

[0004]

However, the cross-sectional shape of this type of indoor unit is a curved surface having a strong curvature due to a demand for miniaturization. For this reason, the LEDs set on a flat substrate and the cover have a large gap and the gaps are not even, and the light emitted from the LEDs cannot be applied to the cover at a right angle.

Therefore, when the user sees the light emission display of each LED, it looks uneven, and it is difficult to clearly confirm the display items such as the driving state.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an air conditioner in which the display items on the display can be clearly confirmed.

[0007]

In view of the above, according to the present invention, an air conditioner having a display for displaying various functions and a cover for the display is provided with the display. It is characterized in that the substrate is formed by bending corresponding to the shape of the surface of the cover.

[0008]

According to the above structure, even if the cover has a curved shape, the distance between the display and the cover can be reduced.
Therefore, it becomes easy to confirm the display items on the display.

[0009]

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a so-called domestic air conditioner, and an indoor unit 1 of an air conditioner is mounted on a wall in a room. Various functions of the indoor unit 1 of the air conditioner are controlled by the remote controller 3. At the lower position of the front panel 8 of the outer case 2, a light receiving sensor 4 that receives an infrared signal transmitted from the remote controller 3, a plurality of LEDs 130 and 132,
A cover 100 is provided.

A suction port 9 is formed in the front panel 8 of the outer case 2. Below this suction port 9,
The outlet 10 is formed, and the outlet 10
The blades 11 that guide the air blowing direction in the vertical direction.
And a blade 12 for guiding in the left-right direction.

As shown in FIG. 2, the substrate 120 is housed in the indoor unit 1 near the lower end portion 81 of the front panel 8. The light receiving sensor 4 and a plurality of LEDs 130 and 132 are arranged outside the substrate 120.
A cover 100 is arranged in front of these.

In this embodiment, the light receiving sensor 4 is also the substrate 12
0, but not limited to this, the light receiving sensor 4
May be set in a region other than the substrate 120.

The light receiving sensor 4 is preferably an infrared (IR) light receiving element for detecting the temperature near the floor (foot) in the room, and the controller controls the operation of the air conditioner based on the detected temperature. It is supposed to do.

The light receiving sensor 4 is arranged below the front panel 8 and receives an infrared signal from the remote controller 3 which is incident in a range diagonally forward from immediately below the indoor unit 1.

The LEDs 130 and 132 constitute a display device for displaying display items to the user. LED13
The set number of 0 and 132 is arbitrary, and as this LED, for example, one that emits an emission color such as red can be adopted.

As shown in FIG. 2, the substrate 120 is formed in a bent shape in three steps in this embodiment. That is,
The board 120 includes a portion 140 on which two LEDs 130 are mounted and a portion 14 on which two LEDs 132 are mounted.
2 and a portion 144 on which the light receiving sensor 4 is mounted.

These two LEDs 130 and two LEs
As shown in FIG. 3, the D132 are arranged side by side in the left-right direction of the indoor unit 1 and are adjacent to each other.
The LED 30 and the LED 132 are arranged side by side in the vertical direction of the indoor unit 1.

Since the light receiving sensor 4 needs to be attached at an angle close to the downward direction, it is mounted on the lowermost portion 144. An infrared ray receiving angle range of the light receiving sensor 4 is indicated by R in FIG.

Moreover, these parts 140, 142, 1
44 is a cover 10 for each of the LEDs 130, 132.
It is bent at a predetermined angle so that the distances L1 and L2 of 0 with respect to the inner surface 102 are equal and the distances L1 and L2 are as small as possible. The light emitted from the LEDs 130, 132 preferably strikes the cover 100 at a right angle.

However, the present invention is not limited to this, and FIG.
As shown in, the distance L between the four LEDs 130 and 132
1, L2 and the distance L3 between the light receiving sensor 4 may be the same, but they are not necessarily the same.

In any case, by reducing the distances L1, L2 and L3 as much as possible, the user can cover 1
00, the display items by the light emission of the LEDs 130 and 132 can be clearly confirmed, and the light receiving sensor 4 can widely receive the infrared signal from the remote controller 3.

As shown in FIG. 3, a display item group 150 corresponding to the LEDs 130 and 132 is formed by printing on the inner surface of the cover 100 of FIG.

In the display example of FIG. 3, a total of four LEDs 13 are provided.
Display item 15 corresponding to 0, 130, 132, 132
Group 0 is formed. The display item group 150 is formed on a transparent sheet and has LED lighting sections 130a and 132a.
Has a diffusing property.

A large ellipse in FIG. 3 indicates an infrared filter of the light receiving sensor 4 behind the cover 100.

The curved cover 100 itself is transparent or semi-transparent, and a plastic plate or the like can be used.

By the way, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the gist of the present invention.

For example, the number of bent portions of the substrate is three.
The number of LEDs is not limited to four, and may be four or more according to the number of LEDs. Further, the display is not limited to the LED, and other light emitting elements may be used.

[0029]

As described above, according to the present invention, the user can clearly confirm the display items on the display through the cover.
