特開２０１２−１０７８６４号公報JP 2012-107864 A

しかし、運転時、風向を調整するために４枚の風向ベーンがそれぞれ所定の角度で固定、または稼働している。そのため、この所定の角度で固定、または、稼働している風向ベーンが利用者から視認されるため、意匠性を損ねていた。   However, during operation, in order to adjust the wind direction, each of the four wind direction vanes is fixed or operating at a predetermined angle. Therefore, since the wind direction vane fixed or operating at the predetermined angle is visually recognized by the user, the design is impaired.

この発明は、上記のような課題を解決するためになされたものであり、運転時の風向ベーンによる意匠性の悪化を改善した天井埋め込み型の空気調和機を得ることを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a ceiling-embedded air conditioner that has improved the deterioration of design due to wind direction vanes during operation.

この発明に係る天井埋込型空気調和機は、天井裏に設置され、室内側が断面四角形状に開口する本体と、前記本体内に設置され、前記本体の吸込口から吸い込んだ空気を前記本体の吹出口まで送る送風ファンと、前記本体内かつ前記送風ファンより下流に設置され、前記吸込口から吸い込まれた空気と熱交換を行う熱交換器と、前記開口を覆う化粧パネルと、前記吹出口に設置され、送風方向を調整可能な風向ベーンと、を備えた天井埋込型空気調和機であって、前記化粧パネルは、ロの字形状した周辺パネルと、前記周辺パネルの中央部を埋めるように設けられた１枚の板状の中央パネルで構成され、前記天井埋込型空気調和機の運転時、前記風向ベーンは前記化粧パネルの裏面に配置されることを特徴とするものである。
The ceiling-embedded air conditioner according to the present invention is installed in the back of the ceiling and has a main body whose interior side opens in a quadrangular cross-section, and the air that is installed in the main body and sucked from the suction port of the main body. A blower fan that sends to the blower outlet, a heat exchanger that is installed in the main body and downstream from the blower fan and exchanges heat with the air sucked from the suction port, a decorative panel that covers the opening, and the blower outlet The ceiling-embedded air conditioner is provided with a wind vane capable of adjusting the air blowing direction, and the decorative panel fills a square-shaped peripheral panel and a central portion of the peripheral panel The wind vane is arranged on the back surface of the decorative panel when the ceiling-embedded air conditioner is in operation. .

この発明に係る天井埋込型空気調和機は、吹出口に設けた風向ベーンを化粧パネルの裏面に設けたため、室内にいる利用者から風向ベーンは視認できなくなる。よって、運転時、４枚の風向ベーンがそれぞれ所定の方向で固定または稼働していたとしても利用者からは視認されないため、意匠性を損なうことはないという効果を有する。   In the ceiling-embedded air conditioner according to the present invention, since the wind direction vane provided at the air outlet is provided on the back surface of the decorative panel, the wind direction vane cannot be visually recognized by the user in the room. Therefore, even when the four wind direction vanes are fixed or operating in a predetermined direction during operation, the user cannot see the wind direction vanes, so that the design is not impaired.

A configuration of a ceiling-embedded air conditioner according to Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a side cross-sectional view of the ceiling-embedded air conditioner according to Embodiment 1 when operation is stopped. FIG. 2 is an external perspective view of the ceiling-embedded air conditioner according to Embodiment 1 when the operation is stopped. FIG. 3 is a side cross-sectional view of the ceiling-embedded air conditioner according to Embodiment 1 during operation. FIG. 4 is a diagram for explaining an arrangement relationship between an air flow rate of the ceiling-embedded air conditioner according to Embodiment 1 and a decorative panel.

図１に示すように、天井埋込型空気調和機１は、天井裏に設置され室内側が断面四角形状に開口する本体２と、本体２よりも室内側に設けられ天井面３に露出する外観ケース４とを備えている。さらに、天井埋込型空気調和機１の本体２内には、本体２の吸込口１２（後述する）から吸い込んだ空気を本体２の吹出口１３（後述する）まで送る送風ファン５と、本体内２で送風ファン５より下流に設置され、吸込口１２から吸い込まれた空気と熱交換を行う熱交換器６と、本体２内に吸い込まれた空気内の塵や埃を取り除く集塵フィルタ７と、を備えている。また、天井埋込型空気調和機１は、天井面３とフラットとなる化粧パネル８で本体２の開口を覆っている。化粧パネル８は送風ファン５の運転状況に応じて昇降装置９により昇降させられる。   As shown in FIG. 1, a ceiling-embedded air conditioner 1 includes a main body 2 that is installed on the back of a ceiling and has an indoor side opening in a square cross section, and an external appearance that is provided on the indoor side of the main body 2 and exposed to the ceiling surface 3. Case 4 is provided. Further, in the main body 2 of the ceiling-embedded air conditioner 1, a blower fan 5 that sends air sucked from an inlet 12 (described later) of the main body 2 to an outlet 13 (described later) of the main body 2, and a main body A heat exchanger 6 that is installed downstream of the blower fan 5 and exchanges heat with the air sucked from the suction port 12, and a dust collection filter 7 that removes dust and dirt in the air sucked into the main body 2. And. The ceiling-embedded air conditioner 1 covers the opening of the main body 2 with a decorative panel 8 that is flat with the ceiling surface 3. The decorative panel 8 is moved up and down by the lifting device 9 according to the operating status of the blower fan 5.

図２に示すように、本体２は、直方体の箱型形状をしており、室内側が開口するように天井裏に取り付けられている。外観ケース４は、室内側から見て本体２の開口２の周囲を囲うように取り付けられている。すなわち、外観ケース４は板状から中央部を取り除いたロの字形状をしている。さらに、外観ケース４は天井面３とフラットになるよう取り付けられている。もちろん、外観ケース４は天井面に対して完全にフラットでなくても、一見してフラットに見える程度であればよい。   As shown in FIG. 2, the main body 2 has a rectangular parallelepiped box shape, and is attached to the ceiling so that the indoor side is open. The external case 4 is attached so as to surround the periphery of the opening 2 of the main body 2 when viewed from the indoor side. That is, the appearance case 4 has a square shape obtained by removing the central portion from the plate shape. Further, the outer case 4 is attached to be flat with the ceiling surface 3. Of course, the appearance case 4 does not have to be completely flat with respect to the ceiling surface, as long as it looks flat at first glance.

送風ファン５は、図１に示すように、箱型形状の本体２の底部の中央部に設けられている。送風ファン５が回転することで、室内の空気が吸込口１２から吸い込まれ、吹出口１３から吹出される。熱交換器６は、送風ファン５と吹出口１３の間に配置され、送風ファン５の運転により吸込口１２から吸い込まれた空気と熱交換を行う。集塵フィルタ７は、室内側から見て化粧パネル８の裏面側で、吸込口１２と送風ファン５の間に配置され、送風ファン５の運転により吸込口１２から吸い込まれた空気に含まれる塵や埃を取り除く役割を果たしている。   As shown in FIG. 1, the blower fan 5 is provided at the center of the bottom of the box-shaped main body 2. As the blower fan 5 rotates, indoor air is sucked in from the suction port 12 and blown out from the air outlet 13. The heat exchanger 6 is disposed between the blower fan 5 and the blower outlet 13, and exchanges heat with the air sucked from the suction port 12 by the operation of the blower fan 5. The dust collection filter 7 is disposed between the suction port 12 and the blower fan 5 on the back side of the decorative panel 8 when viewed from the indoor side, and is included in the air sucked from the suction port 12 by the operation of the blower fan 5. Plays the role of removing dust.

図１、図２に示すように、化粧パネル８は、ロの字形状の外観ケース４の中央部を埋めるように、かつ、本体２の開口を覆うよう設けられている。化粧パネル８は、ロの字形状した周辺パネル１０と、周辺パネル１０の中央部を埋めるように設けられた四角形の板状の中央パネル１１で構成されている。中央パネル１１は吸込口１２を覆い、周辺パネル１０は吸込口１２及び吹出口１３を覆っている。つまり、ロの字形状した外観ケース４の内側にロの字形状した周辺パネル１０が配置され、さらにその内側に四角形の板状の中央パネル１１が配置される。外観ケース４、周辺パネル１０、中央パネル１１で１枚の板状を形成しており、室内側から見た際、これらは天井面３に対してフラットに取り付けられている。もちろん、外観ケース４、周辺パネル１０、中央パネル１１は天井面３に対して完全にフラットでなくても、一見してフラットに見える程度であればよい。   As shown in FIGS. 1 and 2, the decorative panel 8 is provided so as to fill the central portion of the square-shaped appearance case 4 and to cover the opening of the main body 2. The decorative panel 8 includes a square-shaped peripheral panel 10 and a square plate-shaped central panel 11 provided so as to fill the central portion of the peripheral panel 10. The central panel 11 covers the inlet 12, and the peripheral panel 10 covers the inlet 12 and the outlet 13. That is, the square-shaped peripheral panel 10 is disposed inside the square-shaped appearance case 4, and the rectangular plate-shaped central panel 11 is disposed further inside. The outer case 4, the peripheral panel 10, and the central panel 11 form a single plate, and these are attached flat to the ceiling surface 3 when viewed from the indoor side. Of course, the appearance case 4, the peripheral panel 10, and the center panel 11 may be flat as long as they are not flat with respect to the ceiling surface 3.

続いて、図３を用いて、風向ベーン１４の配置を説明する。なお、図３の矢印は空気の流れすなわち風路を示している。   Then, the arrangement | positioning of the wind direction vane 14 is demonstrated using FIG. In addition, the arrow of FIG. 3 has shown the flow of the air, ie, an air path.

図３に示すように、実施の形態１に係る天井埋込型空気調和機１の昇降装置９は、化粧パネル８のうち、特に周辺パネル１０を昇降させている。天井埋込型空気調和機１の運転が開始すると、送風ファン５の回転が開始する。さらに、並行して、昇降装置９は周辺パネル１０を室内側に移動させる。これにより、室内の空気調和が開始される。   As shown in FIG. 3, the lifting device 9 of the ceiling-embedded air conditioner 1 according to the first embodiment lifts, in particular, the peripheral panel 10 out of the decorative panel 8. When the operation of the ceiling-embedded air conditioner 1 starts, the blower fan 5 starts rotating. Further, in parallel, the lifting device 9 moves the peripheral panel 10 to the indoor side. Thereby, indoor air conditioning is started.

昇降装置９により、周辺パネル１０が室内側に移動すると、周辺パネル１０と中央パネル１１の間に隙間でき、この隙間が天井埋込型空気調和機１の吸込口１２となる。同様に、周辺パネル１０が室内側に移動すると、周辺パネル１０と外観ケース４の間に隙間でき、この隙間が天井埋込型空気調和機１の吹出口１３となる。すなわち、天井埋込型空気調和機１運転停止時には、図１に示すように外観ケース４、周辺パネル１０、中央パネル１１は天井面３にフラットかつ隙間なく配置しているため、吸込口１２及び吹出口１３は形成されず、運転時に周辺パネル１０が室内側に移動することで、吸込口１２、吹出口１３が形成される。すなわち、吸込口１２はロの字形状のものが一つ形成され、吹出口１３も、ロの字形状のものが一つ形成される。   When the peripheral panel 10 is moved indoors by the lifting device 9, a gap is formed between the peripheral panel 10 and the central panel 11, and this gap becomes the air inlet 12 of the ceiling-embedded air conditioner 1. Similarly, when the peripheral panel 10 moves to the indoor side, a gap is formed between the peripheral panel 10 and the appearance case 4, and this gap becomes the air outlet 13 of the ceiling-embedded air conditioner 1. That is, when the ceiling-embedded air conditioner 1 is stopped, the appearance case 4, the peripheral panel 10, and the central panel 11 are arranged flat on the ceiling surface 3 with no gaps as shown in FIG. The air outlet 13 is not formed, and the suction port 12 and the air outlet 13 are formed by the peripheral panel 10 moving to the indoor side during operation. That is, one suction port 12 is formed in a square shape, and one outlet port 13 is also formed in a square shape.

天井埋込型空気調和機１の運転が開始すると、室内の空気が吸込口１２より、本体２内に吸い込まれる。そして、本体２内に吸い込まれた空気は集塵フィルタ７、送風ファン５、熱交換器６、順次通過することで空気調和され、吹出口１３より室内に吹き出される。   When the operation of the ceiling-embedded air conditioner 1 starts, indoor air is sucked into the main body 2 from the suction port 12. The air sucked into the main body 2 passes through the dust collection filter 7, the blower fan 5, the heat exchanger 6, and the air is conditioned to be blown into the room through the outlet 13.

図３に示すように、天井埋込型空気調和機１には、さらに、吹出口１３の内側壁面側に風向ベーン１４が設けられている。風向ベーン１４の角度を調整することで室内に吹き出される空気の送風方向を調整することができる。また、この風向ベーン１４は化粧パネル８、特に周辺パネル１０の裏面に配置している。さらに、風向ベーン１４の端部は化粧パネル８特に周辺パネルの１０の端部よりも内側にくるように配置している。   As shown in FIG. 3, the ceiling-embedded air conditioner 1 is further provided with a wind direction vane 14 on the inner wall surface side of the air outlet 13. By adjusting the angle of the wind direction vane 14, the air blowing direction blown into the room can be adjusted. Further, the wind direction vane 14 is disposed on the back surface of the decorative panel 8, particularly the peripheral panel 10. Furthermore, the end of the wind vane 14 is arranged so as to be inside the end of the decorative panel 8, particularly the peripheral panel 10.

図１、図３に示すように、天井埋込型空気調和機１の運転停止時及び運転時ともに、風向ベーン１４は、化粧パネル８特に、周辺パネル１０の裏面にあるため、利用者からは視認されない。   As shown in FIGS. 1 and 3, the wind vane 14 is located on the back surface of the decorative panel 8, particularly the peripheral panel 10, both when the ceiling-embedded air conditioner 1 is stopped and operated. Not visible.

また、昇降装置９による周辺パネル１０の室内側への移動量、すなわち下降量は、室内へ供給する空気の送風方向に応じて変更してもよい。図４に示すように、例えば、図４（ａ）は天井に沿うように送風する場合、図４（ｃ）は室内にいる人に気流感を感じさせるように送風する場合、図４（ｂ）は図４（ａ）と図４（ｃ）の中間の場合、を示している。図４（ａ）の場合、風向ベーン１４は天井面３とほぼ平行になるため、風向ベーン１４の稼働エリアを広く確保する必要がない。よって、昇降装置９による周辺パネル１０の下降量は少しでよい。一方、図４（ｃ）の場合、風向ベーン１４の端部を室内の居住エリア方向に向けるため、風向ベーン１４の稼働エリアをより広く確保する必要がある。よって、昇降装置９による周辺パネル１０の下降量を多くする必要がある。周辺パネル１０の下降量が少ない方が室内から見てよりフラットに見えるため意匠性に優れる。そのため、天井に沿うように送風する場合も、一律に、気流感を感じさせるように送風する場合と同じ下降量にすると、意匠性が損なわれてしまう。よって、送風方向に応じて周辺パネル１０の下降量を調整することで意匠性を向上させることができる。   Further, the amount of movement of the peripheral panel 10 to the room side by the lifting device 9, that is, the amount of descent may be changed according to the blowing direction of the air supplied to the room. As shown in FIG. 4, for example, FIG. 4A shows a case where air is blown along the ceiling, and FIG. 4C shows a case where air is sent so that a person in the room feels airflow. ) Shows an intermediate case between FIG. 4 (a) and FIG. 4 (c). In the case of FIG. 4A, since the wind direction vane 14 is substantially parallel to the ceiling surface 3, it is not necessary to ensure a wide operating area of the wind direction vane 14. Therefore, the amount by which the peripheral panel 10 is lowered by the lifting device 9 is small. On the other hand, in the case of FIG. 4C, since the end portion of the wind direction vane 14 is directed toward the indoor living area, it is necessary to secure a wider operating area of the wind direction vane 14. Therefore, it is necessary to increase the descending amount of the peripheral panel 10 by the lifting device 9. Since the one where the lowering amount of the peripheral panel 10 is smaller looks flatter when viewed from the room, the design is excellent. For this reason, even when the air is blown along the ceiling, the design is impaired if the amount of airflow is uniformly lowered so as to make the airflow feel. Therefore, the designability can be improved by adjusting the descending amount of the peripheral panel 10 according to the blowing direction.

他にも、昇降装置９による、周辺パネル１０の下降量は、室内へ供給する送風量に応じて変更してもよい。例えば、図４（ａ）は送風量が「弱」の場合、図４（ｂ）は送風量が「中」の場合、図４（ｃ）は送風量が「強」の場合を示している。図４（ａ）の時は、室内への送風量が少ないため、吹出口１３の大きさは小さくてもよい。よって、昇降装置９による周辺パネル１０の下降量は少しでよい。一方、図４（ｃ）の時は、室内への送風量が多いため、吹出口１３の大きさは大きくなくてはならない。よって、昇降装置９による周辺パネル１０の下降量は多くする必要がある。送風量が「小」の場合も、一律に送風量「強」の場合と同じ下降量にすると、意匠性が損なわれる。よって、送風量に応じて周辺パネルの下降量を調整することで意匠性を向上させることができる。   In addition, the lowering amount of the peripheral panel 10 by the lifting device 9 may be changed according to the amount of air supplied to the room. For example, FIG. 4A shows a case where the air flow rate is “weak”, FIG. 4B shows a case where the air flow rate is “medium”, and FIG. 4C shows a case where the air flow rate is “strong”. . In the case of FIG. 4A, since the amount of air blown into the room is small, the size of the outlet 13 may be small. Therefore, the amount by which the peripheral panel 10 is lowered by the lifting device 9 is small. On the other hand, at the time of FIG.4 (c), since there is much ventilation volume to room | chamber interior, the magnitude | size of the blower outlet 13 must be large. Therefore, the descending amount of the peripheral panel 10 by the lifting device 9 needs to be increased. Even in the case where the air flow rate is “small”, if the amount of airflow is uniformly reduced as in the case where the air flow rate is “strong”, the design is impaired. Therefore, the design can be improved by adjusting the descending amount of the peripheral panel in accordance with the air flow rate.

実施の形態１に係る天井埋込型空気調和機は、吹出口に設けた風向ベーンを化粧パネルの裏面に設けたため、室内にいる利用者から風向ベーンは視認できなくなる。よって、運転時、４枚の風向ベーンがそれぞれ所定の方向で固定または稼働していたとしても利用者からは視認されないため、意匠性を損なうことはないという特有の効果を奏する。   In the ceiling-embedded air conditioner according to Embodiment 1, the wind direction vane provided at the air outlet is provided on the back surface of the decorative panel, so that the wind direction vane cannot be visually recognized by the user in the room. Therefore, even when the four wind direction vanes are fixed or operating in a predetermined direction during operation, they are not visually recognized by the user, so that a design effect is not impaired.

実施の形態２
実施の形態１に係る天井埋込型空気調和機の中央パネルは四角形の板状であり、かつ周辺パネルと中央パネルが別体で、稼働時分離するのに対し、実施の形態２に係る天井埋込型空気調和機の中央パネルは四角形の格子状であり、かつ周辺パネルと中央パネルが一体となっている。Embodiment 2
The central panel of the ceiling-embedded air conditioner according to the first embodiment is a rectangular plate, and the peripheral panel and the central panel are separate and separated during operation, whereas the ceiling according to the second embodiment The central panel of the embedded air conditioner has a rectangular lattice shape, and the peripheral panel and the central panel are integrated.

実施の形態２に係る天井埋込型空気調和機については図５から図７を用いて説明する。図５は実施の形態２に係る天井埋込型空気調和機の運転停止時の側面断面図であり、図６は実施の形態２に係る天井埋込型空気調和機の運転停止時の室内側から見た外観平面図であり、図７は実施の形態２に係る天井埋込型空気調和機の運転時の側面断面図である。なお、本実施の形態２では実施の形態１との相違点を中心に説明し、実施の形態１と同様の構成及び効果については省略する。また、実施の形態１と同一の構成については同一の符号を用いる。   The ceiling-embedded air conditioner according to Embodiment 2 will be described with reference to FIGS. FIG. 5 is a side sectional view when the operation of the ceiling-embedded air conditioner according to the second embodiment is stopped, and FIG. 6 is a diagram illustrating the indoor side when the operation of the ceiling-embedded air conditioner according to the second embodiment is stopped. FIG. 7 is a side cross-sectional view of the ceiling-embedded air conditioner according to Embodiment 2 during operation. In the second embodiment, differences from the first embodiment will be mainly described, and the same configurations and effects as those of the first embodiment will be omitted. Further, the same reference numerals are used for the same configurations as those of the first embodiment.

図５、図６に示すように、実施の形態２に係る化粧パネル１７は、ロの字形状の外観ケース４の中央部を埋めるように、かつ、本体２の開口を覆うよう設けられている。化粧パネル１７は、ロの字形状した周辺パネル１６と、周辺パネル１６の中央部を埋めるように設けられた四角形の格子状の中央パネル１５で一体に形成されている。中央パネル１５は吸込口１８を覆い、周辺パネル１６は吹出口を覆っている。つまり、ロの字形状した外観ケース４の内側にロの字形状した周辺パネル１６が配置され、さらにその内側に四角形の格子状の中央パネル１５が配置される。外観ケース４、周辺パネル１６、中央パネル１５で１枚の板状を形成しており、室内側から見た際、これらは天井面３に対してフラットに取り付けられている。もちろん、外観ケース４、周辺パネル１６、中央パネル１５は天井面３に対して完全にフラットでなくても、一見してフラットに見える程度であればよい。   As shown in FIGS. 5 and 6, the decorative panel 17 according to the second embodiment is provided so as to fill the central portion of the square-shaped appearance case 4 and to cover the opening of the main body 2. . The decorative panel 17 is integrally formed with a square-shaped peripheral panel 16 and a square lattice-shaped central panel 15 provided so as to fill the central portion of the peripheral panel 16. The center panel 15 covers the inlet 18 and the peripheral panel 16 covers the outlet. In other words, a square-shaped peripheral panel 16 is arranged inside the square-shaped appearance case 4, and a rectangular lattice-shaped central panel 15 is arranged inside the square-shaped peripheral panel 16. The outer case 4, the peripheral panel 16, and the central panel 15 form a single plate, and these are attached flat to the ceiling surface 3 when viewed from the indoor side. Of course, the appearance case 4, the peripheral panel 16, and the center panel 15 do not have to be completely flat with respect to the ceiling surface 3, as long as they look flat at first glance.

図７に示すように、実施の形態２に係る天井埋込型空気調和機１の昇降装置９は、化粧パネル１７すなわち、周辺パネル１６及び中央パネル１５を一体に昇降させている。天井埋込型空気調和機１の運転が開始すると、送風ファン５の回転が開始する。さらに、並行して、昇降装置９は化粧パネル１７を室内側に移動させる。これにより、室内の空気調和が開始される。   As shown in FIG. 7, the lifting device 9 of the ceiling-embedded air conditioner 1 according to the second embodiment lifts the decorative panel 17, that is, the peripheral panel 16 and the central panel 15 together. When the operation of the ceiling-embedded air conditioner 1 starts, the blower fan 5 starts rotating. Further, in parallel, the lifting device 9 moves the decorative panel 17 to the indoor side. Thereby, indoor air conditioning is started.

昇降装置９により、化粧パネル１７が室内側に移動すると、周辺パネル１６と外観ケース４の間に隙間でき、この隙間が天井埋込型空気調和機１の吹出口１３となる。すなわち、天井埋込型空気調和機１運転停止時には、図１に示すように外観ケース４、周辺パネル１６、中央パネル１５は天井面３にフラットかつ隙間なく配置しているため、吹出口１３は形成されず、運転時に化粧パネル１７が室内側に移動することで、吹出口１３が形成される。一方、中央パネル１５は格子状をしているため格子の隙間が吸込口１８となる。   When the decorative panel 17 is moved indoors by the lifting device 9, a gap is formed between the peripheral panel 16 and the external case 4, and this gap becomes the air outlet 13 of the ceiling-embedded air conditioner 1. That is, when the operation of the ceiling-embedded air conditioner 1 is stopped, the appearance case 4, the peripheral panel 16, and the central panel 15 are arranged flat on the ceiling surface 3 with no gaps as shown in FIG. The blower outlet 13 is formed when the decorative panel 17 moves to the indoor side during operation without being formed. On the other hand, since the central panel 15 has a lattice shape, a gap between the lattices serves as a suction port 18.

天井埋込型空気調和機１の運転が開始すると、室内の空気が吸込口１８より、本体２内に吸い込まれる。そして、本体２内に吸い込まれた空気は集塵フィルタ７、送風ファン５、熱交換器６、順次通過することで空気調和され、吹出口１３より室内に吹き出される。   When the operation of the ceiling-embedded air conditioner 1 starts, indoor air is sucked into the main body 2 from the suction port 18. The air sucked into the main body 2 passes through the dust collection filter 7, the blower fan 5, the heat exchanger 6, and the air is conditioned to be blown into the room through the outlet 13.

このように、実施の形態２に係る天井埋込型空気調和機は、稼働時にも周辺パネルと中央パネルが一体となって移動するため、周辺パネルと中央パネルに段差が生じない。よって、実施に形態１に係る効果に加え、さらに意匠性が向上するという効果を有する。   As described above, the ceiling-embedded air conditioner according to the second embodiment moves while the peripheral panel and the central panel move together even during operation, so that there is no step between the peripheral panel and the central panel. Therefore, in addition to the effect which concerns on Embodiment 1, it has the effect that the designability improves further.
