Description

本発明は、赤外線を用いた遠隔操作装置を具備した空気調和機の受信性能向上に関するものである。   The present invention relates to an improvement in reception performance of an air conditioner equipped with a remote control device using infrared rays.

図４は、一般的な壁掛けタイプの空気調和機と遠隔操作装置の位置関係を示す図であり、室内機５の運転時に前面パネルがせり出してくると、受信素子が前面パネルの陰になり、遠隔操作装置１０からの赤外線信号が到達し難くなり受信範囲が狭くなるが、従来のこの種の問題の対応技術としては図５に示すように受光素子前面に設けられた受光窓の内側に赤外線を乱反射させる光拡散剤を塗布することにより受信性能を向上したものが有る（例えば特許文献１参照）。   FIG. 4 is a diagram showing the positional relationship between a general wall-mounted air conditioner and a remote control device. When the front panel protrudes during the operation of the indoor unit 5, the receiving element is behind the front panel, Although it is difficult for the infrared signal from the remote control device 10 to reach and the reception range is narrow, as a conventional technology for dealing with this type of problem, as shown in FIG. 5, an infrared ray is placed inside the light receiving window provided on the front surface of the light receiving element. Some have improved reception performance by applying a light diffusing agent that diffusely reflects light (see Patent Document 1, for example).

特開平１１−６９４６６号公報JP-A-11-69466

しかしながら上記従来の構成では、光拡散剤の塗布により近傍からの赤外信号であれば広範囲に信号を受信することが可能となるが、光拡散剤の塗布により受光窓を透過出来る赤外線の率が低下するため、すこし離れた所から送信される赤外線信号については信号が弱くなっており受光窓を透過出来ず信号が成立しない場合が有る。   However, in the above-mentioned conventional configuration, it is possible to receive a signal in a wide range if the infrared signal is from the vicinity by applying the light diffusing agent. Therefore, there is a case where the infrared signal transmitted from a slightly distant place is weak and cannot be transmitted through the light receiving window.

又、遠隔操作装置内部の電源として利用している電池の消耗により赤外線信号の送信強度が低くなった場合も同様に信号が受光窓を透過出来ず、光拡散剤を塗布しないものに比べ、早めに電池を交換しなければならない等の問題が有る。又、光拡散剤は高価であると共に、塗布作業にも工数を必要とするため不経済である。   Also, when the transmission intensity of the infrared signal is low due to the exhaustion of the battery used as the power source inside the remote control device, the signal cannot be transmitted through the light receiving window in the same manner, and it is earlier than the case where the light diffusing agent is not applied. There are problems such as having to replace the battery. In addition, the light diffusing agent is expensive and uneconomical because it requires man-hours for the coating operation.

本発明は、前記従来の課題を解決するもので、広範囲に赤外線信号を受信することが可能になると共に、安価に実現することが可能な空気調和機を提供することを目的とするものである。   The present invention solves the above-described conventional problems, and an object of the present invention is to provide an air conditioner that can receive infrared signals in a wide range and can be realized at low cost. .

前記従来の課題を解決するために、本発明の空気調和機は受信素子近傍に反射板を設けることにより、赤外信号を広範囲に受信することが出来る。   In order to solve the conventional problems, the air conditioner of the present invention can receive an infrared signal in a wide range by providing a reflector near the receiving element.

本発明の空気調和機は、室内機に配置された受信素子の近傍に反射板を備え、この反射板により遠隔操作装置より送信される赤外線信号を反射させ受光素子に信号を入力する構造とすることにより、より広い範囲で空気調和機を遠隔操作することが出来、使用者の利便性を向上できる。   The air conditioner of the present invention includes a reflector in the vicinity of a receiving element disposed in an indoor unit, and has a structure in which an infrared signal transmitted from a remote control device is reflected by this reflector and a signal is input to the light receiving element. Thus, the air conditioner can be remotely operated in a wider range, and the convenience for the user can be improved.

第１の発明は、受信素子の近傍に受信性能を向上するための少なくとも１枚以上の赤外線信号を反射するための反射板を設けることにより、広い範囲で遠隔操作装置からの送信信号を受信することが可能となる。   In the first invention, a transmission signal from a remote control device is received in a wide range by providing at least one reflector for reflecting infrared signals for improving reception performance in the vicinity of the receiving element. It becomes possible.

第２の発明は、前記反射板を受信素子近傍に配置される樹脂部品の一部を利用することにより、部品点数の削減が可能となる。   In the second invention, the number of parts can be reduced by utilizing a part of the resin parts arranged in the vicinity of the receiving element.

第３の発明は、前記第２の発明で説明した樹脂部品を白色とすることにより、赤外線の反射効率を向上することが可能となる。   In the third invention, it is possible to improve the infrared reflection efficiency by setting the resin component described in the second invention to white.

第４の発明は、反射板をアルミシートとし、前記第２の発明で説明した樹脂部品の反射面に貼り付けることにより、反射効率を向上させることが出来る。   In the fourth invention, the reflecting plate can be made of an aluminum sheet, and the reflection efficiency can be improved by sticking the reflecting plate to the reflecting surface of the resin component described in the second invention.

第５の発明は、前記第４の発明で説明したアルミシートをシボ加工が施されたアルミシートとすることにより、シボ加工による乱反射効果を利用してより広範囲に赤外線信号を受信することが可能となる。   In the fifth aspect of the present invention, the aluminum sheet described in the fourth aspect of the invention is an aluminum sheet that has been subjected to graining, so that it is possible to receive infrared signals over a wider range using the irregular reflection effect of graining. It becomes.

（実施の形態１）
以下、本発明の実施の形態について図面を参照しながら説明する。図１は、本発明の第１の実施形態における空気調和機の室内機側面の部分断面図で、受信素子１と表示素子３をプリント配線板８に、はんだを用いて電気的に接続された受信ブロック（図示せず）が室内機５の一部に配置されている。 (Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional view of a side surface of an indoor unit of an air conditioner according to a first embodiment of the present invention, in which a receiving element 1 and a display element 3 are electrically connected to a printed wiring board 8 using solder. A receiving block (not shown) is arranged in a part of the indoor unit 5.

受信素子１の前面には赤外線信号を透過する透過パネル２が、室内機５上に配置されると共に、表示素子３の前面には、表示素子３相互の光漏れを防ぐための壁と表示素子３の光を室内機５の表面に見栄え良く表示するための導光板を併せ持つ樹脂部品４が配置されており、箱体１０の受信素子２近傍には、反射板７が配置されている。   A transmission panel 2 that transmits an infrared signal is disposed on the front surface of the receiving element 1 on the indoor unit 5, and a wall and a display element for preventing light leakage between the display elements 3 are disposed on the front surface of the display element 3. A resin component 4 having a light guide plate for displaying the light 3 on the surface of the indoor unit 5 is arranged, and a reflector 7 is arranged near the receiving element 2 of the box 10.

６は室内機５の一部で、空気調和機の運転／停止時に開閉を行なう前面パネルで、運転時には室内機５の前面にせり出し、室内の空気を室内機内に吸入し易くする。   Reference numeral 6 denotes a part of the indoor unit 5, which is a front panel that opens and closes when the air conditioner is operated / stopped. The front panel protrudes to the front of the indoor unit 5 during operation to facilitate the intake of indoor air into the indoor unit.

前記構成による第１の実施形態の効果を説明すると、赤外線信号を透過させる透過パネル２は、遠隔操作装置１０より送信されてくる赤外線信号を受信素子１に到達させるためのものであるが、透過性能を有するため、他の構造体を構成する樹脂材料とは色合いが違うので意匠上出来る限り狭い面積を要望される場合が多く、受信性能とのトレードオフで形状が決められる場合が通常である。   The effect of the first embodiment having the above-described configuration will be described. The transmissive panel 2 that transmits an infrared signal is for transmitting an infrared signal transmitted from the remote control device 10 to the receiving element 1. Because it has performance, it has a different color from the resin materials that make up other structures, so there are many cases where the smallest possible design area is required, and the shape is usually determined by a trade-off with reception performance. .

このような設計の中で、空気調和機の運転時に前面にせり出してくる前面パネル６が、遠隔操作装置１０から送信される赤外線信号の光軸Ａと受信素子１の受信可能な範囲の中にせり出してくると、受信素子１の受信可能範囲が前面パネル６の陰になり、Ａ地点より遠方から送信されてくる赤外線信号は受信出来なくなるが、受信素子１の近傍に配置された反射板７により、Ａ地点より遠いＢ地点から送信された赤外線信号が、前面パネル６の下より透過パネル２を透過して入光し、反射板７により反射し受信素子１に入光して受信を成立することが出来る。   In such a design, the front panel 6 protruding to the front during the operation of the air conditioner is within the optical axis A of the infrared signal transmitted from the remote control device 10 and the receivable range of the receiving element 1. When protruding, the receivable range of the receiving element 1 becomes behind the front panel 6 and the infrared signal transmitted from a distance from the point A cannot be received, but the reflector 7 disposed in the vicinity of the receiving element 1. Therefore, the infrared signal transmitted from the point B far from the point A is transmitted through the transmission panel 2 from the bottom of the front panel 6 and is reflected by the reflection plate 7 and enters the receiving element 1 to receive. I can do it.

FIG. 2 is a partial cross-sectional view of the side surface of the indoor unit according to the second embodiment of the present invention, in which the reflector 7 in the first embodiment is integrated with the resin component 4 while reducing the number of components. The same effect can be brought about.

FIG. 3 is a partial cross-sectional view of the side surface of the indoor unit according to the fourth embodiment of the present invention. By attaching an aluminum sheet 9 to the infrared signal reflecting surface of the resin component 4 according to the second embodiment, the reflectance is further increased. And more reliable reception performance can be ensured.

（実施の形態５）
本発明の第５の実施形態は、前記の第４の実施形態にて説明したアルミシート９に、表面にシボ加工がなされたアルミシートを使用することにより受信素子１の近傍で赤外線信号を乱反射させることが出来るため、より広範囲な受信性能を得ることが出来る。 (Embodiment 5)
In the fifth embodiment of the present invention, an infrared signal is diffusely reflected in the vicinity of the receiving element 1 by using the aluminum sheet 9 having a textured surface on the aluminum sheet 9 described in the fourth embodiment. Therefore, a wider range of reception performance can be obtained.

以上のように、本発明の空気調和機は、受信素子近傍の設置した赤外線信号を反射させる反射板により広範囲な場所から送信されてくる遠隔操作装置からの赤外線通信信号を確実に受信出来る空気調和機を提供出来るものである。   As described above, the air conditioner of the present invention is an air conditioner that can reliably receive an infrared communication signal from a remote control device transmitted from a wide range by a reflector that reflects an infrared signal installed in the vicinity of a receiving element. A machine can be provided.
