Description

本発明は、天井埋込型空気調和機に係り、風路での通風抵抗を低減しモーター入力の低減および低騒音化により省エネを図ることに関するものである。   The present invention relates to a ceiling-embedded air conditioner, and relates to energy saving by reducing ventilation resistance in an air passage, reducing motor input, and reducing noise.

従来の天井埋込型空気調和機では、その本体の下方には略四角形状の化粧パネルが取付けられ部屋に面し、この化粧パネルの中央付近には空気調和機本体への空気の吸込口である略四角形で格子状の吸込グリルと、化粧パネルの各辺に沿って形成されたパネル吹出口を有し、さらに各パネル吹出口には上下風向ベーンを備えて空気調和機を成している。
また、この空気調和機本体の内部にはターボファン、ターボファンの吸込風路を形成するベルマウス、ターボファンを回転駆動するモータ、またターボファンを囲むように略C字形状の熱交換器を立設している。さらに前記略C字形状の熱交換器の2つの端部は熱交換器連結板で連結し全体として略四角形状に形成されている。そして、この略C字形状の2つの端部から伸びた伝熱管にはヘッダーや分配器を収納するための前記熱交換器連結板と本体吹出風路側壁と空気調和機本体側板と空気調和機本体天板、そしてドレンパンで囲まれた配管収納スペースを形成している。
In a conventional ceiling-embedded air conditioner, a substantially rectangular decorative panel is attached to the lower part of the main body, facing the room, and an air inlet to the air conditioner main body is located near the center of the decorative panel. It has a substantially rectangular and grid-like suction grille and panel outlets formed along each side of the decorative panel, and each panel outlet has an up-and-down airflow vane to form an air conditioner. .
In addition, a turbo fan, a bell mouth that forms a suction air passage for the turbo fan, a motor that rotationally drives the turbo fan, and a substantially C-shaped heat exchanger that surrounds the turbo fan are provided inside the air conditioner body. Standing up. Further, the two end portions of the substantially C-shaped heat exchanger are connected to each other by a heat exchanger connecting plate and are formed in a substantially rectangular shape as a whole. The heat transfer pipe extending from the two ends of the substantially C shape has the heat exchanger connecting plate, the main body blowing air passage side wall, the air conditioner main body side plate, and the air conditioner for housing the header and distributor. A piping storage space surrounded by a main body top plate and a drain pan is formed.

さらに、空気調和機本体の下面中央部に本体吸込口と前記本体吸込口の周囲には本体吹出口を有し、化粧パネルの略四角形の吸込グリルの各辺に沿って形成され4つのパネル吹出口に連通するように配置され、各パネル吹出口には上下風向ベーンが配設されている。なお、化粧パネルの角部にはパネル吹出口および左右風向ベーンは配設されていないためパネル吹出口の長手方向(左右方向)には吹出気流制御は不可能である。そして、ドレンパンに溜まった熱交換器で発生する凝縮水であるドレン水を機外に排出するためのドレンポンプは熱交換器の空気流れの下流側に配設されている(例えば、特許文献1参照。)。   Further, the air conditioner main body has a main body inlet and a main body outlet around the main body inlet, and is formed along each side of the substantially rectangular suction grille of the decorative panel. It arrange | positions so that it may connect with an exit, and the up-and-down wind direction vane is arrange | positioned at each panel blower outlet. In addition, since the panel blower outlet and the right-and-left wind direction vane are not arrange | positioned at the corner | angular part of a decorative panel, blowing airflow control is impossible in the longitudinal direction (left-right direction) of a panel blower outlet. And the drain pump for discharging | emitting drain water which is the condensed water which generate | occur | produces with the heat exchanger collected in the drain pan outside the apparatus is arrange | positioned in the downstream of the air flow of a heat exchanger (for example, patent document 1). reference.).

また、別の従来の天井埋込型空気調和機として、化粧パネルのパネル吹出口は略環状の360°開口し、外側羽根車により上下風向ベーン無しに風向制御可能というもがある(例えば、特許文献2参照。)。   Further, as another conventional ceiling-embedded air conditioner, the panel outlet of the decorative panel has a substantially annular 360 ° opening, and the outside impeller can control the wind direction without the vertical wind vanes (for example, patents). Reference 2).

特開平11−148704号公報(第3−4頁、第1−2図)Japanese Patent Laid-Open No. 11-148704 (page 3-4, FIG. 1-2) 特開平11−325498号公報(第6−8頁、第1−2図)JP-A-11-325498 (page 6-8, Fig. 1-2)

従来の天井埋込型空気調和機は上述のように構成され、ある程度低騒音で部屋の温度分布差の抑制が可能である。しかし、吸込グリルの各辺に沿って形成されたパネル吹出口および本体吹出口の長手方向開口幅が狭いことから通風抵抗が増加している。また、化粧パネルのパネル吹出口が形成されていない角部は吸込グリルへ吸込まれる流れが通過するため、パネル吹出口が単純に拡大されると吸込まれる流れをパネル吹出口からの吹出流が阻害し通風抵抗となる。その結果、ターボファンの吸込・吹出風を阻害することからファンモータの消費電力が増加し省エネ性が損なわれる。さらに、略四角形の吸込グリルの各辺に沿って略四角形に連設するパネル吹出口が形成されているため、パネル吹出口を有さない化粧パネルの角部では吹出流が存在しなく部屋内で温度分布が不均一になってしまう。   The conventional ceiling-embedded air conditioner is configured as described above, and can suppress the temperature distribution difference in the room with a certain amount of low noise. However, since the longitudinal opening widths of the panel outlet and the main body outlet formed along each side of the suction grille are narrow, the ventilation resistance is increased. Moreover, since the flow sucked into the suction grille passes through the corner portion where the panel blower outlet of the decorative panel is not formed, the blown flow from the panel blower outlet is changed when the panel blower outlet is simply enlarged. Inhibits ventilation resistance. As a result, the power consumption of the fan motor is increased and the energy saving performance is impaired since the suction and blowing air of the turbo fan is obstructed. Furthermore, since the panel blower outlet connected to the substantially rectangular shape is formed along each side of the substantially rectangular suction grille, there is no blowout flow at the corner of the decorative panel having no panel blower outlet. As a result, the temperature distribution becomes non-uniform.

また、従来の天井埋込型空気調和機の別の例では、360°吹出口を開口し内側、外側羽根車自体により吹出流を上下方向スウィング可能で風向ベーンが不必要なためコストダウンが図れるが、羽根車のような高速回転体がパネル吹出口近傍を回転すると万一手の指を挿入された場合ケガをする恐れがあり、安全性が低い。さらに、全ての吹出口風向ベーンを有さないので風を向けたい角度に変更できない。それにより快適性が損なわれる。   In another example of a conventional ceiling-embedded air conditioner, a 360 ° blowout opening is opened, and the blowout flow can be swung in the vertical direction by the inner and outer impellers. However, if a high-speed rotating body such as an impeller rotates in the vicinity of the panel outlet, there is a risk of injury if a finger is inserted, and safety is low. Furthermore, since it does not have all the air outlet vanes, it cannot be changed to the angle at which the wind is to be directed. This impairs comfort.

本発明は上述のような問題点を解消するためになされたもので、化粧パネルのパネル吹出口及び本体吹出風路をほぼ360°開口しつつ、吸込・吹出流れの干渉による吹出流れの通風抵抗を抑制することにより、ファンモータの消費電力Wmを低減し省エネで、かつ部屋の温度分布差の均一化を図り気流制御性が高く、羽根車のような高速回転体がパネル吹出口に露出せず高品質・高安全性で、運転停止時化粧パネルの開口面を縮小し天井面と一体デザインになるようにデザイン性を向上した天井埋込型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 the ventilation resistance of the blowing flow due to the interference of the suction and blowing flows while opening the panel outlet and the main body blowing air passage of the decorative panel at approximately 360 °. By suppressing the power consumption Wm of the fan motor, energy saving, uniform temperature distribution difference in the room is achieved, air flow controllability is high, and a high-speed rotating body such as an impeller is exposed to the panel outlet. The aim is to obtain a ceiling-embedded air conditioner that has high quality and high safety, and has an improved design so that the opening surface of the decorative panel is reduced and integrated with the ceiling surface when the operation is stopped.

この発明に係る天井埋込型空気調和機は、空気調和機本体が天井裏に埋設され、空気調和機本体の内部にターボファンを備え、このターボファンを囲むように略C字形状の熱交換器を立設し、前記空気調和機本体の下面中央部に本体吸込口と前記本体吸込口の周囲には本体吹出口を有し、さらに空気調和機本体下方には設置される部屋に面する化粧パネルが配設され、前記本体吸込口及び本体吹出口に連通する位置に化粧パネルの吸込グリルと吸込グリルのほぼ全周囲に沿ったパネル吹出口を形成し、少なくともパネル吹出口または本体吹出口のどちらか全ての吹出口に上下風向ベーンを有するものである。   In the ceiling-embedded air conditioner according to the present invention, the main body of the air conditioner is embedded in the back of the ceiling, a turbo fan is provided inside the main body of the air conditioner, and a substantially C-shaped heat exchange so as to surround the turbo fan. The air conditioner main body has a main body inlet and a main body outlet around the main body inlet, and further faces a room installed below the air conditioner main body. A decorative panel is provided, and a panel blowout opening substantially along the entire periphery of the suction grille and the suction grille of the decorative panel is formed at a position communicating with the main body suction opening and the main body blowout opening. Any one of these has an up-and-down wind direction vane in the blower outlet.

また、この発明に係る天井埋込型空気調和機は、空気調和機本体が天井裏に埋設され、空気調和機本体の内部にターボファンを備え、このターボファンを囲むように略C字形状で湾曲された熱交換器を立設し、前記空気調和機本体の下面中央部に本体吸込口と前記本体吸込口の周囲には本体吹出口を有し、さらに空気調和機本体下方には設置される部屋に面する化粧パネルが配設され、前記本体吸込口及び本体吹出口に連通する位置に化粧パネルの吸込グリルと吸込グリルのほぼ全周囲に沿ったパネル吹出口を有すとともに、前記化粧パネルの角部パネル吹出口と角部以外の辺部パネル吹出口に配設された風向ベーンの設定角度が異なるものである。   In the ceiling-embedded air conditioner according to the present invention, the air conditioner body is embedded in the back of the ceiling, and a turbo fan is provided inside the air conditioner body, and is substantially C-shaped so as to surround the turbo fan. A curved heat exchanger is erected, and has a main body inlet and a main body outlet at the center of the lower surface of the air conditioner main body, and is further installed below the air conditioner main body. A decorative panel that faces the room, and has a suction grille of the decorative panel and a panel outlet along substantially the entire circumference of the suction grille at a position communicating with the main body inlet and the main outlet. The setting angles of the wind direction vanes arranged at the corner panel outlets of the panel and the side panel outlets other than the corners are different.

この発明の天井埋込型空気調和機は、空気調和機本体が天井裏に埋設され、前記空気調和機本体の内部にターボファンを備え、このターボファンを囲むように略C字形状の熱交換器を立設し、前記空気調和機本体の下面中央部に本体吸込口と前記本体吸込口の全周囲には本体吹出口を有し、さらに前記空気調和機本体下方には設置される部屋に面する化粧パネルが配設され、前記本体吸込口及び本体吹出口に連通する位置に化粧パネルの吸込グリルとこの吸込グリルのほぼ全周囲に沿ったパネル吹出口を有し、少なくともパネル吹出口または本体吹出口のどちらか全ての吹出口に上下風向ベーンを有するので、従来の4箇所の吹出口に比べ吹出口長手寸法が拡大することにより吹出開口面積が増加するとともに、全ての吹出口に上下風向ベーンを有するので吹出流れの風速・風向を制御でき、吸込流れと吹出流れの干渉を抑制できるので通風抵抗を低減できる。そのため、ターボファンの送風が阻害されなくなるのでターボファンを駆動するためのファンモータの消費電力Wmが低減可能である。またパネル吹出口全てに風向ベーンを有するので全方位で吹出流れの気流制御が可能であるので部屋の温度ムラが抑制できる。その結果、省エネで快適性の高い高品質な空気調和機を得ることができる。   In the ceiling-embedded air conditioner of the present invention, the air conditioner main body is embedded in the back of the ceiling, a turbo fan is provided inside the air conditioner main body, and a substantially C-shaped heat exchange is provided so as to surround the turbo fan. A main body suction port at the center of the lower surface of the air conditioner main body and a main body outlet on the entire periphery of the main body suction port, and a room installed below the air conditioner main body. A facing decorative panel is disposed, and has a suction grille of the decorative panel at a position communicating with the main body inlet and the main body outlet, and a panel outlet along substantially the entire circumference of the suction grille, and at least the panel outlet or Since all the outlets of the main unit have upper and lower airflow direction vanes, the length of the outlet increases compared to the conventional four outlets, and the outlet opening area increases, and all outlets Wind direction Because it has a control over wind speed, wind direction of the air flow, thereby reducing the air flow resistance can be suppressed interference of the suction flow and outlet flow. Therefore, since the blow of the turbo fan is not hindered, the power consumption Wm of the fan motor for driving the turbo fan can be reduced. Further, since all the panel outlets have wind direction vanes, it is possible to control the air flow of the outlet flow in all directions, so that temperature unevenness in the room can be suppressed. As a result, a high-quality air conditioner that is energy-saving and highly comfortable can be obtained.

また、この発明の天井埋込型空気調和機は、空気調和機本体が天井裏に埋設され、空気調和機本体の内部にターボファンを備え、このターボファンを囲むように略C字形状で湾曲された熱交換器を立設し、前記空気調和機本体の下面中央部に本体吸込口と前記本体吸込口の周囲には本体吹出口を有し、さらに空気調和機本体下方には設置される部屋に面する化粧パネルが配設され、前記本体吸込口及び本体吹出口に連通する位置に化粧パネルの吸込グリルと吸込グリルのほぼ全周囲に沿ったパネル吹出口を有すとともに、前記化粧パネルの角部パネル吹出口と角部以外の辺部パネル吹出口に配設された風向ベーンの設定角度が異なるので、化粧パネルの角部のパネル吹出口からの吹出流れとその他の辺部のパネル吹出口からの吹出流れの風向が異なり、吸込空間が確保されることから吸込グリルへの吸込流れとパネル吹出口からの吹出流れの干渉が抑制されターボファンの吸込風が阻害されないので通風抵抗が低減し、ターボファンを駆動するためのファンモータの消費電力Wmが低減可能である。また、上下風向ベーンにより部屋の上下高さ方向全体を一度に送風できるので部屋の温度分布を均一化できる。その結果、省エネで部屋の温度ムラを抑制する高品質な空気調和機を得ることができる。   In the ceiling-embedded air conditioner according to the present invention, the air conditioner main body is embedded in the back of the ceiling, the air conditioner main body includes a turbo fan, and is curved in a substantially C shape so as to surround the turbo fan. The heat exchanger is erected, and has a main body inlet and a main body outlet around the main body inlet, and is installed below the air conditioner body. A decorative panel facing the room is disposed, and has a suction grille of the decorative panel and a panel outlet substantially along the entire circumference of the suction grille at a position communicating with the main body inlet and the main body outlet. Since the setting angle of the wind direction vane arranged at the corner panel outlet and the side panel outlet other than the corner is different, the outlet flow from the corner outlet of the decorative panel and the other side panel Wind direction of the air flow from the air outlet In contrast, because the suction space is secured, interference between the suction flow to the suction grille and the blowout flow from the panel outlet is suppressed, and the suction air of the turbo fan is not obstructed, reducing the ventilation resistance and driving the turbo fan The power consumption Wm of the fan motor can be reduced. Moreover, since the entire vertical height direction of the room can be blown at a time by the vertical wind direction vanes, the temperature distribution in the room can be made uniform. As a result, it is possible to obtain a high-quality air conditioner that saves room temperature unevenness with energy saving.

The turbo fan 3 as a whole is configured by a funnel-shaped shroud 3d that forms a flow path. When the air conditioner is operated, as shown in FIGS. 1 to 4, the air in the room 15 is sucked from the suction grille 2 a by the turbo fan 3 driven by the motor 4 and rotating in the direction of arrow A, and dust and the like are removed by the filter 14. After that, the air is sucked into the turbofan 3 through the turbofan suction air passage 23 a and the bell mouth 5. After that, the air blown out from the turbo fan 3 (thick arrow C) is heated, cooled and dehumidified by the heat exchanger 6 and passes through the main body blowing air passage 16 formed in a substantially rectangular shape, and then connected to the substantially rectangular character. The air blown from the main body outlet 16a and the panel outlets 2b 1 and 2b 2 of the decorative panel 2 to the room 15 while being changed in air direction by the up and down air direction vanes 2c 1 and 2c 2 is air-conditioned.

このように、空気調和機を構成することにより、従来の空気調和機において本体吹出風路側に設置していたドレンポンプの場所や配管収納スペースやドレンパンとして使用していた部分を、本発明では開口して本体吹出風路16として使用できるので、本体吹出口16aおよびパネル吹出口2bの吹出開口面積が増加できるので通風抵抗が低減する。そのため、ターボファン3の送風が阻害されなくなるので、図8に示す従来との本発明に係る天井埋込型空気調和機のターボファン3を駆動するためのモータ4の消費電力Wm比較図のように、本発明の方が従来に比べ20%ほど消費電力を低減可能である。   Thus, by configuring the air conditioner, in the present invention, the location of the drain pump, the piping storage space and the drain pan that were installed on the main body blowing air passage side in the conventional air conditioner are used as openings in the present invention. And since it can use as the main body blowing air path 16, since the blowing opening area of the main body blower outlet 16a and the panel blower outlet 2b can be increased, ventilation resistance reduces. Therefore, since the air blown by the turbo fan 3 is not hindered, the power consumption Wm comparison diagram of the motor 4 for driving the turbo fan 3 of the ceiling-embedded air conditioner according to the present invention shown in FIG. In addition, the power consumption of the present invention can be reduced by about 20% compared to the prior art.

また、図1のように略ロの字形状に連接するパネル吹出口2b全てのパネル吹出口2bに上下風向ベーン2cがそれぞれ配設されているので、図9に示すパネル吹出口風速分布図のようにパネル吹出口2bの開口面積を拡大したことによるパネル吹出口での吹出風速減少分を上下風向ベーン2cの設定角度により増速し吹出風速分布差を抑制でき、さらに部屋の上下風向制御可能としているため、部屋15の全体の温度分布も改善されて快適な空調空間が得られる。なお、図9において、縦軸にパネル吹出口風速、横軸に化粧パネルのパネル吹出口角部からの略ロの字形状全周の距離をとり、図中の□印は本発明の上下風向ベーン無し、▲印は本発明の上下風向ベーン有り、◆印は従来の空気調和機をそれぞれ表している。   Moreover, since the up-and-down wind direction vane 2c is each arrange | positioned at the panel blower outlet 2b of all the panel blower outlets 2b connected in a substantially square shape like FIG. 1, the panel blower outlet wind speed distribution map shown in FIG. In this way, the decrease in the blown wind speed at the panel blower outlet due to the expansion of the opening area of the panel blower outlet 2b can be increased by the set angle of the vertical wind vane 2c, and the difference in the blown wind speed distribution can be suppressed, and further the vertical wind direction of the room can be controlled. Therefore, the temperature distribution of the entire room 15 is also improved, and a comfortable conditioned space can be obtained. In FIG. 9, the vertical axis represents the wind speed at the panel outlet, and the horizontal axis represents the distance from the corner of the decorative panel to the substantially rectangular shape. None, ▲ indicates that there is a vertical vane according to the present invention, and ♦ indicates a conventional air conditioner.

また、本体吹出風路16、パネル吹出口2bの通風抵抗減少分、ターボファン3の送風量が増加できるので、熱交換器6での熱交換量が増加でき温風の温度を上昇可能である。 そして、図5のように空気調和機の運転停止時に上下風向ベーン2cが閉鎖された時にはほぼパネル吹出口2bを封鎖できるので、パネル吹出口が開口していると黒く見えて目立つものであるが、本発明によると設置されている部屋15の天井面で目立たなくデザイン性が高い空気調和機を得ることができる。さらに運転停止時のホコリの機内への進入を抑制でき、清潔が保てるとともに高い空調性能を維持することができる。さらに、従来の空気調和機にあるパネル吹出口2b近傍には高速回転体はないので安全性が保てる。その結果、省エネで、快適性が高く、デザイン性の高い天井埋込型空気調和機を得ることができる。   In addition, since the amount of air flow of the turbo fan 3 can be increased by the amount of decrease in the ventilation resistance of the main body blowing air passage 16 and the panel outlet 2b, the amount of heat exchange in the heat exchanger 6 can be increased and the temperature of the hot air can be raised. . And when the up-and-down wind direction vane 2c is closed when the operation of the air conditioner is stopped as shown in FIG. 5, the panel blowout port 2b can be almost blocked, so that the panel blowout port looks black and stands out. According to the present invention, it is possible to obtain an air conditioner that is not conspicuous on the ceiling surface of the installed room 15 and has high design. In addition, dust can be prevented from entering the machine when the operation is stopped, and cleanliness can be maintained and high air conditioning performance can be maintained. Further, since there is no high-speed rotating body in the vicinity of the panel outlet 2b in the conventional air conditioner, safety can be maintained. As a result, it is possible to obtain a ceiling-embedded air conditioner that is energy-saving, high in comfort, and high in design.

実施の形態2.
以下、本発明の実施の形態2における天井埋込型空気調和機を図10〜図15を用いて説明する。
図10は図1に相当する本発明にかかる天井埋込型空気調和機の外観斜視図、図11は図4に相当する図10の空気調和機本体下部における外観平面図、図12は図5に相当する化粧パネルの外観平面図を示す。なお、空気調和機本体内部における構成、および対応する符号は実施の形態1と同一のものを示す。
Embodiment 2. FIG.
Hereinafter, a ceiling-embedded air conditioner according to Embodiment 2 of the present invention will be described with reference to FIGS.
10 is an external perspective view of the ceiling-embedded air conditioner according to the present invention corresponding to FIG. 1, FIG. 11 is an external plan view of the lower part of the air conditioner main body of FIG. 10 corresponding to FIG. 4, and FIG. The external appearance top view of the decorative panel equivalent to is shown. The configuration inside the air conditioner body and the corresponding reference numerals are the same as those in the first embodiment.

図10、図11に示すように、空気調和機本体1は水平断面が略八角形であり、本体中央部の本体吸込口11aに対応して連通する位置に化粧パネル2の略八角形の吸込グリル2aを配設し、本体吹出口16aに対応して連通する位置に吸込グリル2aのほぼ全周囲に略八角形に連設配置するパネル吹出口2b、2bを配設するものである。この実施の形態2における前述の実施の形態1との違いは、吸込グリル2aが略八角形をなす点と、パネル吹出口2bも略八角形に配置された構成となっている点である。これらの構成としたことにより、従来に比べ吹出開口面積が増加し、さらに実施の形態1の図1のように略ロの字形状に配置したパネル吹出口2b、2bを連設する場合に比べて、図11、図12のように空気調和機本体形状に即してパネル吹出口2b、2bを開口することから有効的に開口できるので通風抵抗がさらに低減する。そのため、ターボファン3の送風が阻害されなくなるのでターボファンを駆動するためのモータ4の消費電力Wmが図15のように従来に比べ約25%低減可能である。 As shown in FIGS. 10 and 11, the air conditioner main body 1 has a substantially octagonal horizontal cross section, and the substantially octagonal suction of the decorative panel 2 at a position communicating with the main body suction port 11 a in the center of the main body. Panel grille outlets 2b 1 and 2b 2 that are arranged in a substantially octagonal manner around almost the entire circumference of the suction grille 2a are arranged at positions where the grille 2a is provided and communicated with the main body outlet 16a. . The difference between the second embodiment and the first embodiment is that the suction grill 2a has a substantially octagonal shape and the panel outlet 2b has a substantially octagonal configuration. By adopting these configurations, the blowout opening area is increased as compared with the conventional case, and the panel blowout ports 2b 1 and 2b 2 arranged in a substantially square shape as shown in FIG. Compared to FIG. 11, since the panel outlets 2b 1 and 2b 2 are opened according to the shape of the air conditioner main body as shown in FIG. 11 and FIG. 12, the ventilation resistance is further reduced. For this reason, since the air blowing of the turbo fan 3 is not hindered, the power consumption Wm of the motor 4 for driving the turbo fan can be reduced by about 25% compared to the conventional case as shown in FIG.

また、本発明のパネル吹出口2bを略八角形に連設配置するとともに吸込グリルもそれに対応して略八角形とする構成により、従来の空気調和機のように吸込グリル2aが略四角形の場合に比べ、図12のように化粧パネルの角部2dに対応して形成された角部パネル吹出口2bと吸込グリル2aの距離Bが拡大するので、図13に示すような従来の天井埋込型空気調和機で単純にパネル吹出口2bを拡大した場合(図中の吸込グリルとパネル吹出口との間の距離Bが狭くなった構成)のような吹出流れと吸込流れの干渉が、本発明では生じることなく、図14の本発明での吸込グリル2aと角部パネル吹出口2b近傍の縦断面図に示す気流の流れ状態のように、吸込グリル2aへの吸込流れと角部パネル吹出口2bの吹出流れの干渉が抑制される。そのため通風抵抗がさらに低減し、ターボファン3の送風が阻害されなくなるので、図15の「パネル吹出口が略八角形に連接時+吸込グリルが略八角形時」に示すようにターボファン3を駆動するためのモータ4の消費電力Wmがさらに低減し従来に比べて約30%低減可能である。その結果、さらに省エネが図れた空気調和機を得ることができる。 Further, when the panel outlet 2b of the present invention is continuously arranged in a substantially octagonal shape and the suction grille has a corresponding octagonal shape, the suction grille 2a is substantially rectangular as in a conventional air conditioner. in comparison, the distance B of the formed corresponding to the corner portion 2d of the decorative panel the and corner panel outlet 2b 1 suction grille 2a is enlarged as shown in FIG. 12, implantation conventional ceiling as shown in FIG. 13 When the panel air outlet 2b is simply expanded with a built-in air conditioner (the configuration in which the distance B between the suction grille and the panel air outlet in the figure is reduced), the interference between the air flow and the air suction flow is without resulting in the present invention, as the air current flow conditions shown in the longitudinal sectional view of a suction grille 2a and the corner panel outlet 2b 1 near the present invention in FIG. 14, the suction flow and the corner portion of the suction grille 2a interference of the air flow of the panel blow-out port 2b 1 There is suppressed. For this reason, the ventilation resistance is further reduced and the air flow of the turbo fan 3 is not hindered. Therefore, as shown in FIG. 15 "when the panel outlet is connected to a substantially octagonal shape + when the suction grill is a substantially octagonal shape" The power consumption Wm of the motor 4 for driving is further reduced, and can be reduced by about 30% compared to the conventional case. As a result, an air conditioner with further energy saving can be obtained.

実施の形態3.
以下、本発明の実施の形態3.における天井埋込型空気調和機を図16〜図22を用いて説明する。
図16は図5に相当する化粧パネル2を部屋から見たときの外観平面図、図17は化粧パネル2の角部2dの角部パネル吹出口2b、およびそこに設けた上下風向ベーン2c1のまわりの縦部分断面図、図18は角部以外の辺部パネル吹出口2bに配設された上下風向ベーン2cのまわりの縦部分断面図を示す。なお、空気調和機本体1の内部における主な構成、および対応する符号は実施の形態1と同一のものを示す。
Embodiment 3 FIG.
Embodiment 3 of the present invention will be described below. The ceiling-embedded air conditioner will be described with reference to FIGS.
FIG. 16 is an external plan view of the decorative panel 2 corresponding to FIG. 5 when viewed from the room. FIG. 17 is a corner panel outlet 2b 1 of the corner 2d of the decorative panel 2 and the vertical wind vane 2c provided there. longitudinal partial cross-sectional view around the 1, FIG. 18 shows a longitudinal partial cross-sectional view around the disposed side panel air outlet 2b 2 except corners vertical airflow direction vane 2c 2. In addition, the main structure inside the air conditioner main body 1 and a corresponding code | symbol show the same thing as Embodiment 1. FIG.

図16〜図18において、本発明が前述の実施の形態1または2と異なる点は、本発明では化粧パネル2の吸込グリル2aと吸込グリル2aのほぼ全周囲に連設するパネル吹出口2bを有し、かつ化粧パネルの角部2dの角部パネル吹出口2bに配設された角部上下風向ベーン2cの設定角度θ1と角部以外の対向した辺部にある辺部パネル吹出口2bに配設された辺部上下風向ベーン2cの設定角度θ2が異なるところである。
そのため、化粧パネルの角部2dの角部パネル吹出口2bからの吹出流れと角部以外の他の辺部パネル吹出口2bからの吹出流れの風向が異なり、吸込空間が確保されることから吸込グリル2aへの吸込流れとパネル吹出口2bからの吹出流れの干渉が抑制され通風抵抗が低減できるので、ターボファン3の吸込・吹出流れが阻害されずターボファン3を駆動するためのモータ4の消費電力Wmがさらに低減可能である。
16 to 18, the present invention is different from the above-described first or second embodiment in that the suction grill 2 a of the decorative panel 2 and the panel outlet 2 b that is connected to almost the entire periphery of the suction grill 2 a are provided in the present invention. a, and the side panel air outlet at the sides facing the other set angle θ1 and the corner portion of which is disposed at a corner panel outlet 2b 1 of the corner portion 2d of the decorative panel corner vertical airflow direction vane 2c 1 The setting angle θ2 of the side up / down wind direction vane 2c 2 arranged in 2b 2 is different.
Therefore, different wind direction of the air flow from the side panel air outlet 2b 2 of other than the outlet flow and the corners of the corner corner panel outlet 2b 1 of the 2d of the decorative panel, that the suction space is ensured Since the interference between the suction flow to the suction grille 2a and the blowout flow from the panel blower outlet 2b is suppressed and the ventilation resistance can be reduced, the motor for driving the turbofan 3 without impeding the suction / blowing flow of the turbofan 3 The power consumption Wm of 4 can be further reduced.

例えば、図19の表に空気調和機の冷暖房運転モードおよび風向制御モードでの辺部上下風向ベーン2cの角度θ2、角部上下風向ベーン2c1の角度θ、風向の一例を示す。図19において、暖房1、冷房1(急速、通常)ではθ<θで部屋15へ吹出す場合、図20の(a)に示すように角部上下風向ベーン2c1は(b)の辺部上下風向ベーン2cと異なる角度で比較して上方に吹出すことにより、吸込グリル2aへ吸込流れが流れる空間を確保し、吸込流れと吹出流れの干渉を抑制する。また、図21に示すように、暖房2、冷房2(通常広範囲)では、上下風向ベーンが上下回動(スイング)し、θ1<θ2またはθ>θ2でθ1とθ2が交互に拡大、縮小するバタ足状に吹出される。さらに、図22に示すように、暖房3、冷房3(安定運転時)の場合は、辺部上下風向ベーン2cを閉鎖し、角部上下風向ベーン2c1のみを開口し風向制御することにより必要最小限の空調が可能である。このように部屋15の上下高さ方向全体と周方向全体を一度に送風できるので部屋15の温度分布が均一化できる。その結果、省エネで部屋の温度ムラを抑制する高品質な空気調和機を得ることができる。 For example, table angle θ2 of the side portion vertical airflow direction vane 2c 2 in cooling and heating operation mode and direction control mode of the air conditioner, the angle theta 1 corner vertical airflow direction vane 2c 1 of FIG. 19 shows an example of the wind direction. In FIG. 19, in the case of heating 1 and cooling 1 (rapid, normal), when blowing to the room 15 with θ 12 , as shown in FIG. 20A, the corner vertical wind vane 2 c 1 is as shown in FIG. By comparing and blowing upward at a different angle from the side vertical airflow direction vane 2c 2 , a space for suction flow to the suction grille 2a is secured, and interference between the suction flow and the blowout flow is suppressed. Further, as shown in FIG. 21, in the heating 2 and cooling 2 (usually wide range), the vertical wind vanes rotate up and down (swing), and θ 1 and θ 2 satisfy θ 12 or θ 1 > θ 2. It is blown out like a butterfly that alternately expands and contracts. Further, as shown in FIG. 22, in the case of heating 3 and cooling 3 (during stable operation), the side vertical air vane 2c 2 is closed and only the corner vertical air vane 2c 1 is opened to control the air direction. Minimal air conditioning is possible. As described above, since the entire vertical height direction and the entire circumferential direction of the room 15 can be blown at once, the temperature distribution in the room 15 can be made uniform. As a result, it is possible to obtain a high-quality air conditioner that saves room temperature unevenness with energy saving.

実施の形態4.
以下、本発明の実施の形態4における天井埋込型空気調和機を図23〜図25を用いて説明する
図23は図1に相当する本発明にかかる天井埋込型空気調和機の運転停止時における外観斜視図、図24は図23の縦断面図、図25は図24のD部の化粧パネル2の吸込グリル開閉機構部縦断面図を示す。なお、空気調和機本体1の内部における主な構成、および対応する符号は実施の形態1と同一のものを示す。
Embodiment 4 FIG.
Hereinafter, the ceiling-embedded air conditioner according to the fourth embodiment of the present invention will be described with reference to FIGS. 23 to 25. FIG. 23 is the operation stop of the ceiling-embedded air conditioner according to the present invention corresponding to FIG. FIG. 24 is a longitudinal sectional view of FIG. 23, and FIG. 25 is a longitudinal sectional view of the suction grill opening / closing mechanism portion of the decorative panel 2 in the D portion of FIG. In addition, the main structure inside the air conditioner main body 1 and a corresponding code | symbol show the same thing as Embodiment 1. FIG.

本発明における天井埋込型空気調和機において、前述の実施の形態1から3と異なる点は、本体下方に取り付けられる化粧パネル2のほぼ中央部にある吸込グリル2aに関する部分が異なるものである。図25の吸込グリル開閉機構部を示す縦断面図において、吸込グリル2aより本体内側に設けられた吸込グリル開閉アーム2eに軸固定されて回動自在に取り付けられた吸込グリル格子2fを備えるとともに、この吸込グリル開閉アーム2eの一端部が歯車を有したグリル開閉用モータ19に噛合う歯型形状を有している。そして、空気調和機の運転稼動時、図25の吸込グリル開閉アーム2eがグリル開閉用モータ19により水平移動し吸込グリル格子2fは回動して吸込グリル2aは開口し、また空気調和機の運転停止時、図25の吸込グリル開閉アーム2eがグリル開閉用モータ19により逆に水平移動し吸込グリル格子2fは回動して吸込グリル2aは閉鎖し、風向ベーン2cも回動してパネル吹出口2bが閉鎖され、図23のように吸込グリルを通した機内が見えづらい状態になる。   In the ceiling-embedded air conditioner according to the present invention, the difference from the first to third embodiments described above is that the portion related to the suction grill 2a at the substantially central portion of the decorative panel 2 attached below the main body is different. In the longitudinal cross-sectional view showing the suction grill opening and closing mechanism portion of FIG. 25, the suction grill opening and closing arm 2e provided on the inside of the main body from the suction grill 2a is provided with a suction grill grid 2f that is pivotally attached and rotatably mounted. One end of the suction grill opening / closing arm 2e has a tooth shape that meshes with the grill opening / closing motor 19 having a gear. When the air conditioner is in operation, the suction grill opening / closing arm 2e shown in FIG. 25 is moved horizontally by the grill opening / closing motor 19, the suction grill grid 2f is rotated and the suction grill 2a is opened, and the air conditioner is operated. At the time of stop, the suction grill opening / closing arm 2e of FIG. 25 is horizontally moved reversely by the grill opening / closing motor 19, the suction grill lattice 2f is rotated, the suction grill 2a is closed, and the wind direction vane 2c is also rotated to rotate the panel outlet. 2b is closed, and it becomes difficult to see the inside of the machine through the suction grille as shown in FIG.

このように空気調和機を形成することにより、運転停止時には、パネル吹出口の上下風向ベーン2cによる開口部閉鎖状態と吸込グリルの閉鎖状態とをなすことで化粧パネルにおける開口がほぼなくなり、黒く見える部分がほとんどないため、設置されている部屋の天井面に一体化できデザイン性が高い空気調和機を得ることができる。また、パネル吹出口及び吸込グリルが蓋をした状態となるため、ホコリの機内への侵入をさらに抑制でき清潔が保てるとともに、高い空調能力を維持することが可能となる。   By forming the air conditioner in this way, when the operation is stopped, the opening in the panel blower outlet by the up-and-down air direction vane 2c and the closed state of the suction grille are almost eliminated, so that the opening in the decorative panel almost disappears and looks black. Since there are almost no parts, it is possible to obtain an air conditioner that can be integrated with the ceiling surface of the installed room and has high design. Further, since the panel outlet and the suction grille are covered, dust can be further prevented from entering the machine and cleanliness can be maintained, and high air conditioning capability can be maintained.

実施の形態5.
以下、本発明の実施の形態5における天井埋込型空気調和機を図26〜図29を用いて説明する
図26は図1に相当する本発明にかかる天井埋込型空気調和機の外観斜視図、図27は図26の縦断面図、図28は図26の矢視Eから見たパネル吹出口拡大図を示す。
なお、空気調和機本体1の内部における主な構成、および対応する符号は実施の形態1から4と同一のものを示す。
Embodiment 5. FIG.
Hereinafter, a ceiling-embedded air conditioner according to Embodiment 5 of the present invention will be described with reference to FIGS. 26 to 29. FIG. 26 is an external perspective view of the ceiling-embedded air conditioner according to the present invention corresponding to FIG. FIG. 27 is a longitudinal sectional view of FIG. 26, and FIG. 28 is an enlarged view of the panel outlet as seen from the direction of arrow E in FIG.
In addition, the main structure inside the air conditioner main body 1 and a corresponding code | symbol show the same thing as Embodiment 1-4.

本発明の天井埋込型空気調和機は、前述の実施の形態1から4と異なる点は、パネル吹出口2bに上下風向ベーン2cと左右風向ベーン2hの両方を設けた点が異なるところである。図26、図27において、化粧パネル2の中央部にある吸込グリルのほぼ全周囲に略八角形に連設するパネル吹出口2bに上下風向ベーン2cおよび左右風向ベーン2hが配設される。この左右風向ベーン2hは、一例として図28に示すように、化粧パネル2に固定保持された左右風向ベーン回転軸2kを持ち、各左右風向ベーン2hは左右風向ベーンジョイント2Jにより接続され、化粧パネル2に固定されたベーンモータ18の駆動により、左右風向ベーンジョイント2Jを介し連動して回動する。   The ceiling-embedded air conditioner of the present invention is different from the above-described first to fourth embodiments in that both the up-and-down wind direction vane 2c and the left-right wind direction vane 2h are provided in the panel outlet 2b. 26 and 27, a vertical wind vane 2c and a left and right wind vane 2h are disposed at a panel outlet 2b that is provided in a substantially octagonal manner around substantially the entire periphery of the suction grill at the center of the decorative panel 2. For example, as shown in FIG. 28, the left and right wind direction vanes 2h have left and right wind direction vane rotation shafts 2k fixedly held on the decorative panel 2, and the left and right wind direction vanes 2h are connected by left and right wind direction vane joints 2J. When the vane motor 18 fixed to 2 is driven, the vane motor 18 rotates in conjunction with the left and right wind direction vane joints 2J.

これにより、従来の空気調和機では吹出口内部に左右風向ベーン2hは配設されていないので空気調和機の設置位置によって人に吹出風を直接当てたい場合や空気調和機下方にいる人が吹出風を避けたい場合には上下風向ベーン2cのみでしか風向制御ができなかったが、本実施の形態によれば、左右風向ベーン2hが配設されていることにより、上下風向ベーン2cと相まって自在に風向制御可能であるので、部屋15に居る人の欲しい場所へ風向を変更可能で快適性が向上し高品質な空気調和機が得られる。   As a result, in the conventional air conditioner, the right and left wind vanes 2h are not arranged inside the air outlet, so that it is necessary to directly apply the blown air to the person depending on the installation position of the air conditioner or the person below the air conditioner When it is desired to avoid the wind, the wind direction can be controlled only by the up / down wind direction vane 2c. However, according to the present embodiment, the left / right wind direction vane 2h is arranged, so that it can be freely combined with the up / down wind direction vane 2c. Therefore, the wind direction can be changed to a place desired by a person in the room 15, and the comfort is improved and a high-quality air conditioner is obtained.

さらに、全ての左右風向ベーン2hの設置角度をターボファンの回転方向Aの方向に設定した場合、元々ターボファン3への吸込流れは回転方向Aと同様な旋回流で吸込グリル2aへ流入されており、パネル吹出口2b、2bが吸込グリル2aのほぼ全周囲に配設されていることから、パネル吹出口2b、2bの吹出流は図29に示すように吸込流れと干渉することなく旋回流を形成し、吸込グリル2a近傍がパネル吹出口2b、2b近傍に比べさらに負圧になるため、吸込グリル2aへの吸込流れが促進される。そのため、ターボファン3の吸込側通風抵抗が低減され、ターボファン3を駆動するためのファンモータの消費電力Wmが低減可能である。また、吹出流れは旋回流となるため、床面への吹出流れの到達距離が拡大し、天井面の高い部屋に本発明の天井埋込型空気調和機を設置しても床まで風が到達できるので部屋の温度ムラが改善できる。その結果、さらに省エネで高品質な空気調和機を得ることができる。 Further, when the installation angles of all the left and right wind direction vanes 2h are set in the direction of the rotational direction A of the turbofan, the suction flow into the turbofan 3 originally flows into the suction grille 2a in the same swirl flow as in the rotation direction A. Since the panel outlets 2b 1 and 2b 2 are disposed almost all around the suction grill 2a, the outlet flow of the panel outlets 2b 1 and 2b 2 interferes with the suction flow as shown in FIG. A swirl flow is formed without any negative pressure, and the vicinity of the suction grille 2a becomes more negative than the vicinity of the panel outlets 2b 1 and 2b 2 , so that the suction flow to the suction grille 2a is promoted. Therefore, the suction side ventilation resistance of the turbo fan 3 is reduced, and the power consumption Wm of the fan motor for driving the turbo fan 3 can be reduced. In addition, since the blown flow becomes a swirl flow, the reach of the blown flow to the floor is expanded, and the wind reaches the floor even if the ceiling-embedded air conditioner of the present invention is installed in a room with a high ceiling. This can improve room temperature unevenness. As a result, a further energy-saving and high-quality air conditioner can be obtained.

Hereinafter, the ceiling-embedded air conditioner according to Embodiment 6 of the present invention will be described with reference to FIGS. 30 to 34.

図30において、空気調和機本体1の内部にはターボファン3、ターボファン吸込風路23aを形成するベルマウス5、ターボファン3を回転駆動するモータ4を配設し、また熱交換器6はターボファン3を囲むように略C字形状に立設し、熱交換器6の2つの端部6aから伸びた伝熱管6bに接続されたヘッダー8や分配器9が接続されターボファン吹出風路23bに露出している。
また、図30および図32にように、熱交換器6の空気流れの下流側から空気調和機本体天板1b、空気調和機本体側板1a、ドレンパン12に囲まれ化粧パネル2のパネル吹出口2bへ連通する本体吹出口16a、本体吹出風路16、熱交換器6と隔絶された別の風路を形成し、一例として外気導入用風路24としている。
In FIG. 30, the air conditioner body 1 is provided with a turbo fan 3, a bell mouth 5 that forms a turbo fan suction air passage 23a, and a motor 4 that rotationally drives the turbo fan 3, and a heat exchanger 6 A turbo fan blowout air passage is installed in a substantially C shape so as to surround the turbo fan 3 and is connected to a header 8 and a distributor 9 connected to a heat transfer pipe 6b extending from two end portions 6a of the heat exchanger 6. 23b is exposed.
30 and 32, the panel outlet 2b of the decorative panel 2 is surrounded by the air conditioner main body top plate 1b, the air conditioner main body side plate 1a, and the drain pan 12 from the downstream side of the air flow of the heat exchanger 6. Another air passage that is isolated from the main body outlet 16a, the main body outlet air passage 16, and the heat exchanger 6 is formed as an air passage 24 for introducing outside air.

また、図33に示すように、前記外気導入用風路24と別の角部吹出風路16fは他の本体風路16と隔絶された風路を形成し、一例として図34のような抗酸化成分発生器26を配設した場合を示す。なお、抗酸化成分は空気中の活性酸素の発生を抑制し、人体細胞の酸化を抑制するものである。そして抗酸化成分発生器26は前面に配設された抗酸化成分の一つである天然ハーブを含有したカートリッジ27を背面に配設されたフィルムヒータ28により加熱し天然ハーブ成分を空気中へ供給する仕組みである。   Also, as shown in FIG. 33, the outside air introduction air passage 24 and another corner blowing air passage 16f form an air passage isolated from the other main air passage 16, and as an example, the anti-air flow passage shown in FIG. The case where the oxidation component generator 26 is provided is shown. The antioxidant component suppresses the generation of active oxygen in the air and suppresses the oxidation of human cells. The antioxidant component generator 26 heats a cartridge 27 containing a natural herb which is one of the antioxidant components arranged on the front surface by a film heater 28 arranged on the back surface, and supplies the natural herb components to the air. It is a mechanism to do.

そして、モータ4の運転や上下風向ベーン2cの上下角度制御、室外機との制御信号の送受信を行う制御基板等を収納する電気品箱13が配設され、ターボファン3はモータ4の回転軸を固定するハブ3cと一体に形成された主板3bに、ターボファンの回転方向Aに対し逆向きの後向き羽根である翼3aが取り付けられ、主板3bに対向して翼3aへの空気の案内流路を形成する漏斗状のシュラウド3dにより構成されターボファン3全体が回転する。
そして、図31の本体下部から見た図のように外気導入用風路24、抗酸化発生装置26が配設された角部本体吹出風路16fは開口し、化粧パネル2の角部パネル吹出口2b1へ連通している。
An electrical component box 13 for housing a control board and the like for operating the motor 4 and controlling the vertical angle of the up-and-down air direction vanes 2 c and transmitting and receiving control signals to and from the outdoor unit is disposed. The main plate 3b formed integrally with the hub 3c for fixing the blade is attached with blades 3a, which are backward blades opposite to the rotation direction A of the turbofan, and the air guide flow to the blades 3a is opposed to the main plate 3b. The turbo fan 3 as a whole is configured by a funnel-shaped shroud 3d that forms a path.
Then, as shown in the view from the lower part of the main body of FIG. 31, the outside air introduction air passage 24 and the corner body outlet air passage 16 f provided with the antioxidant generator 26 are opened, and the corner panel blowing of the decorative panel 2 is opened. It communicates with the outlet 2b1.

このように、本体吹出風路16のうち一部の角部本体吹出風路16fを他の本体吹出風路に外気導入する場合、冷房時に熱交換器6で冷やされた空気と外気の温かい空気が混合し吹出風路壁面で結露してしまうため、外気導入した空気を先ず本体吸込風路に吸い込ませる必要があった。しかし、本発明によればその必要が無くなり結露を抑制でき、さらに外気導入用風路面積を大きく取れるので風路圧損が低減できて外気導入効率が向上するとともに外気導入量が増加できる。また、他の例として、外気導入接続部25に酸素発生装置等の他の方式の給気装置を接続しても同様に熱交換器での熱交換後の流れと給気流れが合流しても風路が隔絶されているのでユニット内での結露が防止可能である。   In this way, when the outside air is introduced into some of the main body blowing air passages 16f in the main body blowing air passage 16, the air cooled by the heat exchanger 6 during cooling and the warm air of the outside air Therefore, it is necessary to first suck the air introduced into the air into the main body suction air passage. However, according to the present invention, the necessity is eliminated and condensation can be suppressed. Furthermore, since the outside air introduction air passage area can be increased, the air passage pressure loss can be reduced, the outside air introduction efficiency can be improved, and the outside air introduction amount can be increased. Further, as another example, even if another type of air supply device such as an oxygen generator is connected to the outside air introduction connection portion 25, the flow after heat exchange in the heat exchanger and the supply air flow are merged. Since the air path is isolated, condensation within the unit can be prevented.

さらに、前記外気導入用風路24と別の角部吹出風路16fは他の本体風路16と隔絶された風路を形成し、他の角部本体吹出風路16fを構成することにより、吹出口面積の大きい辺部本体吹出風路16gや角部本体風路16fを他の本体吹出風路16と隔絶しない場合、抗酸化成分が空気調和機本体内部で拡散しすぎてしまう。本発明のように抗酸化成分発生器26の配設される角部本体吹出風路16fが他の本体吹出風路16と隔絶されることにより空気調和機本体内部で抗酸化成分は拡散しずらいので有効に部屋15へ抗酸化成分含有空気を放出できる。なお、抗酸化成分発生器26の代わりにマイナスイオン発生器を配設しても有効にマイナスイオンを部屋15へ放出可能である。
このように本体吹出風路を形成することにより、吹出口面積が拡大し通風抵抗が低減できることからモータ消費電力の低減が可能で、フレッシュエアーを外気導入でき、抗酸化成分含有空気等を有効に部屋へ放出できるので、省エネで高品質・高付加機能の天井埋込型空気調和機が得られる。
Furthermore, the outside air introduction air passage 24 and another corner blowing air passage 16f form an air passage isolated from the other main body air passage 16, and constitute another corner main body blowing air passage 16f. If the side body outlet air passage 16g and the corner body air passage 16f having a large outlet area are not isolated from the other body outlet air passages 16, the antioxidant components are diffused too much inside the air conditioner body. Antioxidant components do not diffuse inside the air conditioner main body because the corner main body blowing air passage 16f in which the antioxidant component generator 26 is disposed is isolated from other main body blowing air passages 16 as in the present invention. Therefore, the antioxidant component-containing air can be effectively released into the room 15. Even if a negative ion generator is provided instead of the antioxidant component generator 26, negative ions can be effectively released into the room 15.
By forming the main body blowing air passage in this way, the blower outlet area can be expanded and the ventilation resistance can be reduced, so the motor power consumption can be reduced, fresh air can be introduced into the outside air, and antioxidant component-containing air etc. can be effectively used Since it can be released into the room, an energy-saving, high-quality, high-functionality ceiling-embedded air conditioner can be obtained.
