Description

本発明は、照明光源を備えた天井埋込型空気調和装置に関する。   The present invention relates to a ceiling-embedded air conditioner including an illumination light source.

一般に、ユニット本体が天井内に埋め込まれ、天井板の天井面に化粧パネルが露出した天井埋込型空気調和装置が知られている（特許文献１参照）。この種のものでは、化粧パネルが略中央に吸込み口を有し、この吸込み口の外方に吹出し口を有し、この吹出し口が４方向又は２方向に配置されているものがある。近年、建屋のインテリアとして例えば天井面に統一された照明ラインを設け、この照明ライン上に、邪魔にならないように天井埋込型空気調和装置を配置することが提案されている。
特開平５−１８７６４９号公報 In general, a ceiling-embedded air conditioner in which a unit main body is embedded in a ceiling and a decorative panel is exposed on a ceiling surface of a ceiling board is known (see Patent Document 1). In this type, the decorative panel has a suction port substantially in the center, and has a blow-out port outside the suction port, and the blow-out ports are arranged in four or two directions. In recent years, it has been proposed that a unified illumination line is provided as an interior of a building, for example, on a ceiling surface, and an air conditioner with a ceiling embedded is arranged on the illumination line so as not to get in the way.
JP-A-5-187649

しかし、従来のものでは、化粧パネルの形状が照明ラインにマッチせず、インテリアデザイン上で違和感が生じる場合がある。   However, in the conventional one, the shape of the decorative panel does not match the lighting line, and there may be a sense of incongruity in the interior design.

また、居間等の居室において、その天井中央部に、天井埋込型空気調和装置を設置した場合、照明光源は、どうしてもこれを避けた対置に設置しなければならず、これによって、居室内の必要な明るさが得られなくなったり、照明光源を居室中央に配置した場合、これを避けた位置に天井埋込型空気調和装置を配置しなければならず、これによって、必要な空調性が得られなくなったり等、インテリアデザイン上で制約を受けるばかりでなく、明るさや空調性を犠牲にする恐れがある。また、一般照明では設計に応じた明るさ（以下、必要な明るさという。）の確保が重要であり、そのためには、ある程度の大きさの照明装置を配置しなければならない場合があり、この場合、天井埋込型空気調和装置の設置スペースが制限される恐れがある。   In addition, when a ceiling-embedded air conditioner is installed in the center of the ceiling of a living room or the like, the illumination light source must be installed in a position opposite to this, and thus, If the necessary brightness cannot be obtained or if the illumination light source is placed in the center of the room, the ceiling-embedded air conditioner must be placed in a location that avoids this, thereby obtaining the required air conditioning. In addition to being restricted by interior design, such as being unable to do so, there is a risk of sacrificing brightness and air conditioning. In general lighting, it is important to ensure brightness according to the design (hereinafter referred to as necessary brightness). To that end, lighting devices of a certain size may have to be arranged. In this case, the installation space of the ceiling-embedded air conditioner may be limited.

そこで、本発明の目的は、照明光源と一体型で、かつ必要な明るさを確保できる天井埋込型空気調和装置を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a ceiling-embedded air conditioner that is integral with an illumination light source and that can ensure the necessary brightness.

上記目的を達成するため、本発明は、ユニット本体が天井内に埋め込まれ、天井板の天井面に化粧パネルが露出した天井埋込型空気調和装置において、この化粧パネルが天井板の天井面に密着して取り付けられた基部と、この基部に連結部を介して取り付けられ、当該基部との間に横吹出しの吹出し口を形成する表面部とを有し、この表面部が略中央に吸込み口を有し、この吸込み口の外方に中空状に形成されて、当該中空内に照明光源を有した照明部を備えたことを特徴とする。   In order to achieve the above object, the present invention provides a ceiling-embedded air conditioner in which a unit body is embedded in a ceiling and a decorative panel is exposed on the ceiling surface of the ceiling panel. A base portion that is closely attached and a surface portion that is attached to the base portion via a connecting portion and that forms a horizontal outlet between the base portion and the surface portion has a suction port substantially at the center. And an illuminating unit which is formed in a hollow shape outside the suction port and has an illumination light source in the hollow.

本発明では、化粧パネルにおいて、基部と表面部とにより横吹出しの吹出し口を形成し、表面部は、略中央に吸込み口を有し、この吸込み口の外方に中空状に形成されて、当該中空内に照明光源を有した照明部を設けたため、一般的な従来の４方向カセット型空調機の化粧パネル等のように、上記吸込み口の外方に横並びに吹出し口を設けない分だけ、照明部を大きく形成することができる。従って、照明光源と一体型で、かつ必要な明るさを充分に確保することができる。   In the present invention, in the decorative panel, the base portion and the surface portion form a horizontal outlet, and the surface portion has a suction port in the approximate center, and is formed in a hollow shape outside the suction port. Since the illumination unit having the illumination light source is provided in the hollow, as in the case of a decorative panel of a general conventional four-way cassette type air conditioner, the side and the outlet are not provided outside the suction port. The illumination part can be formed large. Therefore, it is integrated with the illumination light source and the necessary brightness can be sufficiently secured.

この場合において、前記照明部の少なくとも表面が光透過性を有した部材で形成されていてもよい。また、前記吹出し口が４方向又は２方向に配置されていてもよい。   In this case, at least the surface of the illumination unit may be formed of a light transmissive member. Moreover, the said blowing outlet may be arrange | positioned in 4 directions or 2 directions.

本発明によれば、基部と表面部とにより横吹出しの吹出し口を形成し、表面部は、略中央に吸込み口を有し、この吸込み口の外方に中空状に形成されて、当該中空内に照明光源を有した照明部を設けたため、照明部を大きく形成でき、これによれば、照明光源と一体型で、かつ必要な明るさを確保できる。   According to the present invention, the base portion and the surface portion form a horizontal outlet, and the surface portion has a suction port substantially at the center, and is formed in a hollow shape outside the suction port. Since the illuminating unit having the illuminating light source is provided therein, the illuminating unit can be formed large, and according to this, it is integrated with the illuminating light source and the necessary brightness can be secured.

以下、図面を参照して本発明の一実施形態を詳述する。
図１は、本実施形態による４方向カセット型空調機の断面図、図２は、同じく斜視図、図３は、正面図、図４は、背面図である。各図において、１は空気調和機を示す。この空気調和機１は、天井内部に収納される板金製の筐体２を含んだユニット本体２Ａと、この筐体２の下面に配置される化粧パネル７とを備えて構成される。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1 is a sectional view of a four-way cassette type air conditioner according to the present embodiment, FIG. 2 is a perspective view, FIG. 3 is a front view, and FIG. 4 is a rear view. In each figure, 1 shows an air conditioner. The air conditioner 1 includes a unit main body 2A including a sheet metal casing 2 housed inside the ceiling, and a decorative panel 7 disposed on the lower surface of the casing 2.

２７はターボファン１２と、天板１３に取り付けられたモータ１４とからなる遠心送風機であり、１６は熱交換器２１の下面を覆うように配置され、角張った環形状に発泡スチロールで形成されたドレンパンであり、２１はターボファン１２の吐出側にこのファンを取り囲むように環状に配置されたプレートフィン型の熱交換器である。また、２３は熱交換器２１で熱交換された空気を吹出し口４へ導く吹き出し空間、２４は筐体２を吊具で天井梁に吊下げるための吊下げボルトである。   A centrifugal blower 27 includes a turbo fan 12 and a motor 14 attached to the top plate 13. A drain pan 16 is disposed so as to cover the lower surface of the heat exchanger 21, and is a drain pan formed of foamed polystyrene in an angular ring shape. Reference numeral 21 denotes a plate fin type heat exchanger arranged in an annular shape on the discharge side of the turbo fan 12 so as to surround the fan. Reference numeral 23 denotes a blow-out space for guiding the air heat-exchanged by the heat exchanger 21 to the blow-out port 4, and 24 denotes a suspension bolt for suspending the casing 2 from the ceiling beam with a suspension tool.

上記化粧パネル７は、天井の開口部５を塞ぐように、天井板６の天井面６Ａに密着した状態で、筐体２の下面に取り付けられた基部７１と、この基部７１に、４隅に配置された柱状の連結部７３（図２）を介して取り付けられ、基部７１との間に横吹出しの吹出し口４を形成する表面部７５とを備えて構成されている。各吹出し口４には、風向変更用のフラップ９が配置されている。   The decorative panel 7 has a base 71 attached to the lower surface of the housing 2 in close contact with the ceiling surface 6A of the ceiling plate 6 so as to close the opening 5 of the ceiling, and the base 71 has four corners. It is attached via a column-shaped connecting portion 73 (FIG. 2) that is arranged, and is provided with a surface portion 75 that forms a horizontal outlet 4 with the base 71. A wind direction changing flap 9 is disposed at each outlet 4.

化粧パネル７の表面部７５は、概略中央に吸込み口３を有し、この吸込み口３の入口部に、化粧グリル８を備え、この化粧グリル８に空気清浄用のフィルタ２５を支持して構成されている。そして、表面部７５は、吸込み口３の外方に、４辺に亘って中空状に形成された照明部１１を有し、この照明部１１は、中空部１１Ｃを有すると共に、少なくとも室内側の面材１１Ａと、４つの側面材１１Ｂとが、光透過性を有した部材、例えば乳白色のシェード部材で形成されている。   The surface portion 75 of the decorative panel 7 has a suction port 3 in the approximate center, and a makeup grill 8 is provided at the inlet of the suction port 3, and the filter 25 for cleaning air is supported on the makeup grill 8. Has been. And the surface part 75 has the illumination part 11 formed in the hollow shape over four sides on the outer side of the suction inlet 3, and while this illumination part 11 has 11 C of hollow parts, at least indoor side The face material 11A and the four side face materials 11B are formed of a light-transmitting member, for example, a milky white shade member.

この照明部１１には、サークル状の蛍光管等の照明光源１３が収納され、この照明部１１は、照明光源１３を収納するのに必要な厚みＨを有し、かつ全体的に居室内の明るさを充分に維持できるように、所定幅Ｗの大きさを持って形成されている。この照明部１１では、面材１１Ａを通しての照明が直接照明となり、側面材１１Ｂを通しての照明が間接照明となる。この照明部１１は、化粧パネル７の吸込み口３の外方に、それぞれ４辺に亘って、一体的に形成されており、外観的には、図２〜図４に示すように、化粧パネル７とまったく一体である。   The illumination unit 11 accommodates an illumination light source 13 such as a circle-shaped fluorescent tube, and the illumination unit 11 has a thickness H necessary for accommodating the illumination light source 13 and is entirely inside the living room. It is formed with a predetermined width W so that the brightness can be sufficiently maintained. In the illumination unit 11, illumination through the face material 11A is direct illumination, and illumination through the side material 11B is indirect illumination. The illumination unit 11 is integrally formed on the outside of the suction port 3 of the decorative panel 7 over the four sides, and as shown in FIGS. 7 is completely integrated.

この空気調和機１では、図示を省略した室外機から、上記熱交換器２１に冷媒が供給され、ここに吸込み口３を経由して、遠心送風機２７により室内の空気が循環し、この室内の空気が冷媒により、加熱または冷却され、フラップ９で風向が制御されて、吹出し口４から４方向に風が吹出される。   In this air conditioner 1, refrigerant is supplied to the heat exchanger 21 from an outdoor unit (not shown), and indoor air is circulated by the centrifugal blower 27 through the suction port 3. The air is heated or cooled by the refrigerant, the wind direction is controlled by the flap 9, and the wind is blown out in four directions from the outlet 4.

一般に、この空気調和機１は、例えば２０畳程度までの大きさの居室であれば、室内の天井略中央の理想のポジションに設置される。この場合、照明装置もまた室内の天井略中央の理想のポジションに設置することが望ましい。本構成では、この空気調和機１を、居間等における居室天井略中央の理想のポジションに設置することで、照明光源を、同理想のポジションに同時に取り付けることができる。従って、居室内の必要な明るさと、必要な空調性とを同時に得ることができる。   In general, if the air conditioner 1 is a room having a size of, for example, about 20 tatami mats, the air conditioner 1 is installed at an ideal position approximately in the center of the indoor ceiling. In this case, it is desirable that the lighting device is also installed at an ideal position approximately in the center of the indoor ceiling. In this configuration, by installing the air conditioner 1 at an ideal position substantially in the center of the living room ceiling in a living room or the like, the illumination light source can be simultaneously attached to the ideal position. Therefore, necessary brightness in the living room and necessary air conditioning can be obtained at the same time.

必要な明るさは、光源によって決まり、これにはサークル状の蛍光管以外でも、例えば、高輝度ＬＥＤやその他スリム管等の小さく、薄い物が好適である。本構成では、化粧パネル７の吸込み口３の外方に、４辺に亘って厚みＨおよび幅Ｗの照明部１１を備え、光源の大きさが決まれば、それに応じて、照明部１１の厚みＨおよび幅Ｗを適宜変更すればよく、簡単な構成で、必要な明るさを容易に得ることができる。   The necessary brightness depends on the light source. For this purpose, a small and thin object such as a high-intensity LED or other slim tube is suitable other than the circular fluorescent tube. In this structure, the illumination part 11 of thickness H and width W is provided over the four sides outside the suction port 3 of the decorative panel 7, and if the size of the light source is determined, the thickness of the illumination part 11 is accordingly changed. What is necessary is just to change H and the width W suitably, and required brightness can be obtained easily with a simple structure.

本構成では、一般的な照明器具と同じ明るさを持つ照明機能を、化粧パネル７に一体化させたため、空調機および天井照明のレイアウトが簡便化され、天井面をすっきりさせることができる。また、天井レイアウト設計を同時に進行させることができ、工期短縮や工費削減が図られる。また、例えば人感センサを設置して、空調機および天井照明を同時制御する場合、システム化が簡素化される。   In this configuration, since the lighting function having the same brightness as that of a general lighting fixture is integrated with the decorative panel 7, the layout of the air conditioner and the ceiling lighting is simplified, and the ceiling surface can be cleaned. In addition, the ceiling layout design can be advanced at the same time, and the construction period can be shortened and the construction cost can be reduced. Further, for example, when a human sensor is installed and the air conditioner and the ceiling lighting are simultaneously controlled, the systemization is simplified.

本構成では、化粧パネル７にて、基部７１と表面部７３とにより横吹出しの吹出し口４を形成し、表面部７３は、略中央に吸込み口３を有し、この吸込み口３の外方に中空状に形成されて、当該中空内に照明光源１３を有した照明部１１を設けたため、室内側下面には、化粧グリル８と照明部１１だけが露出する。従って、天井面をすっきりとさせることができる。また、一般的な従来の４方向カセット型空調機の化粧パネル等のように、吸込み口３の外方に横並びに吹出し口が存在しない分だけ、照明部１１の幅Ｗを大きく形成することができ、設計要求に応じた明るさを容易に確保できる。   In this configuration, the decorative panel 7 includes the base portion 71 and the surface portion 73 to form the horizontal outlet 4, and the surface portion 73 has the suction port 3 at the substantially center, and the outside of the suction port 3. Since the illuminating unit 11 having the illumination light source 13 is provided in the hollow, only the decorative grill 8 and the illuminating unit 11 are exposed on the lower surface on the indoor side. Therefore, the ceiling surface can be made clear. Moreover, the width W of the illuminating part 11 can be increased by the amount that there is no sideways and outlets outside the suction port 3 as in a decorative panel of a general conventional four-way cassette type air conditioner. The brightness according to the design requirement can be easily secured.

また、基部７１と表面部７３とを、柱状の連結部７３により連結して、横吹出しの吹出し口４を形成しているため、これら柱状の連結部７３を任意の位置に移動させることにより、側面部の任意の位置に吹出し口４を配置することができ、これによれば、周囲吹出し等、空調性を向上させることができる。   Moreover, since the base 71 and the surface part 73 are connected by the column-shaped connection part 73 and the blowout port 4 of the horizontal blowing is formed, by moving these columnar connection parts 73 to arbitrary positions, The air outlet 4 can be arranged at an arbitrary position on the side surface, and according to this, air-conditioning performance such as ambient air can be improved.

本構成では、照明部１１を、吸込み口３の外方に設けたため、照明部１１の内側の例えば化粧グリル８等を、従来と同様の構成とすることができる。この化粧グリル８は、フィルタ２５の清掃メンテナンス時に着脱されるが、この化粧グリル８には、照明機能を持たせていない。従って、この化粧グリル８には、電気配線等の接続がなく、その脱着をきわめて容易に行うことができる。   In this structure, since the illumination part 11 was provided in the outer side of the suction inlet 3, the makeup grilles 8 etc. inside the illumination part 11 can be set as the structure similar to the past. The decorative grill 8 is attached and detached during cleaning maintenance of the filter 25, but the decorative grill 8 does not have an illumination function. Accordingly, the decorative grill 8 has no connection such as electric wiring and can be attached and detached very easily.

また、照明部１１を、吸込み口３の外方に設けたことにより、略中央部の吸込み口３の大きさを、従来通りに大きく形成することができる。さらに、化粧パネル７の基部７１を、図１を参照して、吸込み口３の外方に、幅Ｗ１に亘って大きく張り出させたため、ユニット本体２Ａの据え付けが、多少図中左右にずれたとしても、この基部７１が、天井開口５を完全に塞ぐため、ユニット本体２Ａの据え付けが、多少ラフであってもよく、据え付け容易なものになる。   Further, by providing the illumination unit 11 outside the suction port 3, the size of the suction port 3 at the substantially central portion can be made larger as usual. Further, since the base 71 of the decorative panel 7 is greatly extended over the width W1 to the outside of the suction port 3 with reference to FIG. 1, the installation of the unit body 2A is slightly shifted left and right in the drawing. However, since the base 71 completely closes the ceiling opening 5, the installation of the unit main body 2A may be somewhat rough and easy to install.

また、図１に示すように、照明部１１の室内側の面と、化粧グリル８の室内側の面とを、略面一に構成しているため、室内側から見て、従来の薄型の化粧パネルと同様の美的外観を得ることができる。   Further, as shown in FIG. 1, the indoor side surface of the illumination unit 11 and the indoor side surface of the decorative grill 8 are configured to be substantially flush with each other. An aesthetic appearance similar to that of a decorative panel can be obtained.

また、上述した天井埋込型空気調和機１では、筐体２がほぼ正方形であるため、一般に普及された簡易天井パネル（ジプトーン）１枚を外した場合、そこにぴったり収まるサイズになり、施工性を向上させることができる。
この場合、本体は約８５０ｍｍ角程度、化粧パネル７は照明部１１の大きさにもよるが、例えば１１５０ｍｍ角程度に形成すればよい。 Further, in the above-described ceiling-embedded air conditioner 1, since the casing 2 is almost square, when one commonly used simple ceiling panel (ziptone) is removed, the size fits there and is installed. Can be improved.
In this case, the main body is about 850 mm square, and the decorative panel 7 may be formed to be about 1150 mm square, for example, depending on the size of the illumination unit 11.

以上、一実施形態に基づいて本発明を説明したが、本発明は、これに限定されるものでないことは明らかである。例えば、上記構成では、４方向カセット型について説明したが、これに限定されず、例えば２方向カセット型あるいは１方向カセット型でも同様の構成が得られる。２方向あるいは１方向の例においても、化粧パネルの表面部７５自体を中空状に形成して、当該中空内に照明光源を配置すればよい。   As mentioned above, although this invention was demonstrated based on one Embodiment, it is clear that this invention is not limited to this. For example, although the four-way cassette type has been described in the above configuration, the present invention is not limited to this. For example, the same configuration can be obtained with a two-way cassette type or a one-way cassette type. Even in the case of two directions or one direction, the surface portion 75 of the decorative panel itself may be formed in a hollow shape, and the illumination light source may be disposed in the hollow.
