A decorative panel using a translucent plate is arranged in the suction port portion in the width direction, and the suction port portion The display unit in which the whole emits light and the light-emitting device is arranged is arranged in the front part between the suction port and the outlet. In such a conventional wall-mounted air conditioner indoor unit, when a display unit is provided on the front panel portion, the LED used for displaying the driving state is expensive and expensive in order to ensure visibility when the lighting is turned on. It is necessary to use a thing with brightness. In addition, in order to prevent malfunction due to noise such as inverter fluorescent lamps, it is necessary to use a filter material that transmits only infrared rays in the light receiving portion of a wireless remote controller that uses infrared rays (Patent Document 1).

しかしながら，特許文献１に用いられる高輝度のＬＥＤは一般的なＬＥＤに対し高価であり、また、赤外線のみを透過する材料は一般材に比べ高価であるなどの問題点がある。

以下、本発明の一実施形態に係る空気調和機の室内機について添付図面を参照して説明する。   Hereinafter, an indoor unit of an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings.

図１は本発明の一実施形態に係る空気調和機の室内機の正面図、図２はその側断面図、図３はその分解斜視図、図４は吸込パネルを除去した状態のその正面図である。   FIG. 1 is a front view of an indoor unit of an air conditioner according to an embodiment of the present invention, FIG. 2 is a side sectional view thereof, FIG. 3 is an exploded perspective view thereof, and FIG. 4 is a front view of a state in which a suction panel is removed. It is.

図１乃至図４に示すように、本実施形態の空気調和機の室内ユニット１は筐体を構成するユニット本体２を備え、このユニット本体２は室内ユニット1前面側を覆う前面パネル３と室内ユニット機能部品が取り付けられる後板４から構成される。   As shown in FIGS. 1 to 4, the indoor unit 1 of the air conditioner of the present embodiment includes a unit main body 2 that constitutes a housing. The unit main body 2 includes a front panel 3 that covers the front side of the indoor unit 1 and an indoor unit. It consists of a rear plate 4 to which unit functional parts are attached.

前記前面パネル３は、吸込口６を形成する前面側上部は開口しており、この前面開口３ａには、その開口を覆うように、ユニット本体１の前面部を構成する板状の吸込パネル５を開閉可能取り付けていると共に、この吸込パネル５の下端部に前面吸込口６を開口させている。また、前面パネル３の上面には上面グリルが嵌め込まれた上部吸込口７が開口され、前面パネル３の下部には熱交換空気の風向を設定するルーバ８を設けた吹出口９が開口される。   The front panel 3 has an upper opening on the front side that forms the suction port 6. The front opening 3 a has a plate-like suction panel 5 that constitutes the front portion of the unit body 1 so as to cover the opening. The front suction port 6 is opened at the lower end of the suction panel 5. Further, an upper suction port 7 into which an upper surface grille is fitted is opened on the upper surface of the front panel 3, and an air outlet 9 provided with a louver 8 for setting the air direction of heat exchange air is opened at the lower part of the front panel 3. .

ユニット本体２内の後板４には、前記吸込口６、７と前記吹出口９の間に送風路１３が形成され、この送風路１３内に前記後板４に取り付けられた熱交換器１２、その下流側に送風機１４が配設されている。   The rear plate 4 in the unit body 2 is formed with an air passage 13 between the suction ports 6 and 7 and the outlet 9, and the heat exchanger 12 attached to the rear plate 4 in the air passage 13. The blower 14 is disposed on the downstream side.

前記熱交換器１２は、前面側に配置される前側熱交換器１２Ａと、背面側に後側熱交換器１２Ｂが側面視逆Ｖ字状に構成され、また、前記送風機１４は横流ファンで構成され前記熱交換器１２の下流側に配置されている。   The heat exchanger 12 includes a front heat exchanger 12A disposed on the front side and a rear heat exchanger 12B disposed on the back side in a reverse V shape when viewed from the side, and the blower 14 includes a cross-flow fan. The heat exchanger 12 is disposed downstream of the heat exchanger 12.

また、前記前側熱交換器１２Ａの吸込側には、電気集塵器１０が取り付けられている。   An electric dust collector 10 is attached to the suction side of the front heat exchanger 12A.

さらに、前面パネル３には、前面側吸込口６と吹出口９の間に、前記吸込口６と前記吹出口９とを上下に仕切る仕切板部３ｂが、前記室内ユニット本体２の前面部に幅方向亘って設けられている。   Further, the front panel 3 is provided with a partition plate portion 3b that vertically partitions the suction port 6 and the air outlet 9 between the front side air inlet 6 and the air outlet 9 on the front surface of the indoor unit body 2. It is provided over the width direction.

前記吸込口６前面を覆うように設けられる吸込パネル５の下端縁部は、前記仕切板部３ｂの前方を遮蔽するように前記仕切板部３ｂの前方まで延びると共に前記仕切板部３ｂとの間に間隙を形熱交換空気の上下方向の風向を設定する吹出用のルーバ８を設け成し、この下部の間隙を前面側吸込口６として構成させている。   A lower end edge portion of the suction panel 5 provided so as to cover the front surface of the suction port 6 extends to the front of the partition plate portion 3b so as to shield the front of the partition plate portion 3b, and between the partition plate portion 3b. A blow-out louver 8 is provided in the upper portion to form a vertical direction of the heat exchange air, and the lower gap is configured as a front side suction port 6.

さらに、仕切板部３ｂの前方を遮蔽するように仕切板部３ｂの前方に延びた吸込パネル５はわずかに湾曲しており、仕切板部３ｂの一部も上記湾曲に合わせこれと略々平行になるように傾斜する傾斜部３ｃが設けられている。   Further, the suction panel 5 extending in front of the partition plate portion 3b so as to shield the front of the partition plate portion 3b is slightly curved, and a part of the partition plate portion 3b is also substantially parallel to the above curve. An inclined portion 3c is provided so as to be inclined.

図５乃至図７に示すように、仕切板部３ｂには空気調和機の運転状態を表示し、傾斜部３ｃに設けられた取付孔に取り付けられたＬＥＤ表示レンズ１１ａと仕切板部３ｂに近接する制御基板１５に取り付けられたＬＥＤ１１ｂを備えた表示部１１が配置されている。さらに、表示部１１の近傍の傾斜部３ｃには、傾斜部３ｃに設けられた取付孔に取り付けられた受光フィルタ１６ａとリモコンからの赤外線信号を受信し制御基板１５に取り付けられた受光素子１６ｂを備えた受信部１６が設けられる。   As shown in FIGS. 5 to 7, the partition plate portion 3b displays the operating state of the air conditioner, and is close to the LED display lens 11a and the partition plate portion 3b attached to the attachment hole provided in the inclined portion 3c. A display unit 11 including an LED 11b attached to the control board 15 is disposed. Further, the inclined portion 3c in the vicinity of the display portion 11 includes a light receiving filter 16a attached to an attachment hole provided in the inclined portion 3c and a light receiving element 16b attached to the control board 15 for receiving an infrared signal from a remote controller. A receiving unit 16 is provided.

表示部１１及び受信部１６の仕切板部３ｂへの配置は、表示部１１及び受信部１６を制御基板１５に取り付け、この制御基板１５を傾斜部３ｃに近接して対向させ平行になるように収納ケース１５ａを介して後板４に構成するドレンパン１８の前面に取り付けることで行われる。   The display unit 11 and the receiving unit 16 are arranged on the partition plate 3b so that the display unit 11 and the receiving unit 16 are attached to the control board 15, and the control board 15 is opposed to and in parallel with the inclined part 3c. This is done by attaching to the front surface of the drain pan 18 constituting the rear plate 4 via the storage case 15a.

表示部１１をこのような取り付け構造にすることにより、表示部１１は吸込パネル５で遮蔽され正面（水平方向）から見えない状態になる。さらに、表示部１１は傾斜した傾斜部３ｃに設けられており、表示部１１を斜め下方を向いた下部吸込口６を介して見るようにしたので、エアコン本体と同じ高さ、またはエアコン本体より高い位置に設置された照明器具の光が、直接受光素子１６ｂ及びＬＥＤ表示レンズ１１ａに当たらないようにすることにより、天井の照明の光が吸込パネルで遮られ、ＬＥＤ周囲の照度を下げることが出来るため、飾りパネルを介して表示し高輝度で高価なＬＥＤを用いる従来とは異なり、表示部１１に通常の輝度の低いＬＥＤ１１ｂを使用してもＬＥＤ１１ｂの視認性を維持できる。   When the display unit 11 has such an attachment structure, the display unit 11 is shielded by the suction panel 5 and is not visible from the front (horizontal direction). Further, since the display unit 11 is provided on the inclined unit 3c, and the display unit 11 is viewed through the lower suction port 6 facing obliquely downward, it is the same height as the air conditioner body or from the air conditioner body. By preventing the light from the luminaire installed at a high position from directly hitting the light receiving element 16b and the LED display lens 11a, the light from the ceiling illumination is blocked by the suction panel, and the illuminance around the LED can be lowered. Therefore, unlike the conventional case of using a high-brightness and expensive LED displayed via a decorative panel, the visibility of the LED 11b can be maintained even when the LED 11b having a normal low brightness is used for the display unit 11.

また、受光部１６も正面から見えないよう構成することで、受光素子１６ｂに直接照明器具の光が当たらないため、受光フィルタの材料に赤外線のみを透過するフィルタ材料を使用しなくても、インバータ蛍光灯などのノイズによるリモコン受信不良を防ぐことができ、照明器具によるリモコン受信の誤動作の発生を防止することができる。   In addition, since the light receiving unit 16 is also configured so as not to be seen from the front, the light from the lighting device does not directly hit the light receiving element 16b, so that the inverter can be used without using a filter material that transmits only infrared rays as the light receiving filter material. Remote control reception failure due to noise such as a fluorescent lamp can be prevented, and malfunction of remote control reception by a lighting fixture can be prevented.

さらに、ＬＥＤ表示レンズ１１ａと受光フィルタ１６ａを近接して位置出来るため、ＬＥＤ表示レンズ１１ａと受光フィルタ１６ａを一体化した部品にすることが可能になり、さらに、ＬＥＤ１１ｂと受光素子１６ｂを同じ制御基板１５に取り付けることが可能になり、表示基板と受光基板を一体化でき、制御基板１５を小形化することができる。   Further, since the LED display lens 11a and the light receiving filter 16a can be positioned close to each other, the LED display lens 11a and the light receiving filter 16a can be integrated into one part. Further, the LED 11b and the light receiving element 16b can be integrated into the same control board. 15, the display substrate and the light receiving substrate can be integrated, and the control substrate 15 can be miniaturized.

本実施形態の空気調和機の室内機によれば、前面パネルの仕切板部に表示部を設け、この表示部を前面パネルの前面に設けた吸込パネルによりエアコン正面位置から表示部が見えないようにすることにより、安価で輝度の低いＬＥＤを使用してもＬＥＤの視認性が低下せず、室内照明の照度的な影響及びノイズの影響を受けることなく、簡素な構成で認識性及び動作精度を向上させた信頼性の高い空気調和機の室内機が実現される。   According to the indoor unit of the air conditioner of the present embodiment, the display unit is provided on the partition plate portion of the front panel, and the display unit is not seen from the front position of the air conditioner by the suction panel provided on the front surface of the front panel. Therefore, even if cheap and low-brightness LEDs are used, the visibility of the LEDs does not deteriorate, and it is not affected by the illuminance and noise of the interior lighting. A highly reliable indoor unit of an air conditioner with improved air quality is realized.
