Description

本発明は、天井型空気調和機に関し、より詳細には、吐出口を通過する空気の流動抵抗を低減することができる天井型空気調和機に関する。   The present invention relates to a ceiling-type air conditioner, and more particularly to a ceiling-type air conditioner that can reduce the flow resistance of air passing through a discharge port.

一般の天井型空気調和機の例が特許文献１に開示されており、この天井型空気調和機は、熱交換器と送風装置が組み込まれた状態で天井の内部空間に埋め立てられる本体と、本体の下面及び天井の開口部を覆うように設置される天井パネルとを備える。また、この天井型空気調和機は、室内空気の吸入及び吐出のために天井パネルの中央部に形成される吸入口と、天井パネルの吸入口の周りに形成される多数の吐出口とを備える。   An example of a general ceiling-type air conditioner is disclosed in Patent Document 1. This ceiling-type air conditioner includes a main body that is buried in an internal space of a ceiling in a state in which a heat exchanger and a blower are incorporated, and a main body And a ceiling panel installed so as to cover the opening of the ceiling. The ceiling-type air conditioner includes a suction port formed at the center of the ceiling panel for sucking and discharging room air, and a number of discharge ports formed around the suction port of the ceiling panel. .

また、本体内部の送風装置は、通常、天井パネルの中央の吸入口から空気を吸い込んでその円周方向に送り出す遠心型ターボファンと、このターボファンを駆動する駆動モーターとを含む。そして、熱交換器は、ターボファンから送り出される空気が通過しつつ熱交換されるようにターボファンの周りに配置される。   Further, the blower inside the main body usually includes a centrifugal turbofan that sucks air from the suction port at the center of the ceiling panel and sends it out in the circumferential direction, and a drive motor that drives the turbofan. And a heat exchanger is arrange | positioned around a turbo fan so that the air sent out from a turbo fan may heat-exchange while passing.

また、かかる従来の天井型空気調和機の中には、冬期暖房運転を遂行するに際して熱交換器による空気の加熱が充分でない場合に、吐出空気をさらに加熱するために吐出口側に補助ヒーターを設置したものもある。これは、熱交換器を通過した空気が吐出口を通過しつつ補助ヒーターにより再び加熱されるようにすることによって、熱交換器による空気の加熱が充分でない場合にも室内が円滑に暖房されるようにしたものである。ここで、補助ヒーターは、通常、吐出口側に設置されるヒーター支持部材により支持される。   In addition, in such a conventional ceiling type air conditioner, an auxiliary heater is provided on the discharge port side in order to further heat the discharge air when the air is not sufficiently heated by the heat exchanger when performing the winter heating operation. Some are installed. This is because the air that has passed through the heat exchanger is heated again by the auxiliary heater while passing through the discharge port, so that the room can be smoothly heated even when the air is not sufficiently heated by the heat exchanger. It is what I did. Here, the auxiliary heater is normally supported by a heater support member installed on the discharge port side.

ところが、かかる天井型空気調和機は、吐出口側に装着される補助ヒーターとヒーター支持部材などのために吐出口を通過する空気の流動が円滑でない、という問題があった。しかも、このような天井型空気調和機は、ターボファンから送り出される空気がターボファンの回転方向に旋回しながら熱交換器を通過した後に下部の吐出口側に流動するので、空気の流動方向と吐出口の方向が一致しなく流動抵抗が相対的に大きのに加え、その吐出口にヒーター支持部材などがさらに設置されるので、流動抵抗は一層大きくなり、吐出口への送風が円滑でない、という問題があった。   However, such a ceiling type air conditioner has a problem that the flow of air passing through the discharge port is not smooth due to an auxiliary heater and a heater support member mounted on the discharge port side. Moreover, in such a ceiling type air conditioner, the air sent from the turbofan flows to the lower discharge port side after passing through the heat exchanger while turning in the rotation direction of the turbofan, The direction of the discharge port does not match and the flow resistance is relatively large, and since the heater support member and the like are further installed in the discharge port, the flow resistance is further increased, and the air blowing to the discharge port is not smooth, There was a problem.

また、この空気調和機が夏期に冷房運転を遂行する場合には、吐出される冷気とヒーター支持部材との干渉が大きくなってヒーター支持部材の表面温度が低くなるため、ヒーター支持部材で結露現象が起こる、という問題もあった。
大韓民国公開特許公報特２００３−００５９８８９号 In addition, when this air conditioner performs cooling operation in the summer, the interference between the discharged cool air and the heater support member becomes large and the surface temperature of the heater support member becomes low. There was also a problem that happened.

以下、本発明に従う好ましい実施形態について、添付図面を参照しつつ詳細に説明する。   Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

本発明に従う天井型空気調和機は、図１及び図２に示すように、天井１の開口部２から天井１の内部に埋め立てられ、その下面が開放された箱型の本体１０と、本体１０の下面開放部１１及び天井１の開口部２を覆うように本体１０の下端に装着される天井パネル２０とを備える。   As shown in FIGS. 1 and 2, a ceiling-type air conditioner according to the present invention is a box-shaped main body 10 that is buried in the interior of the ceiling 1 from the opening 2 of the ceiling 1, and the lower surface of the box-type main body 10 is opened. And a ceiling panel 20 attached to the lower end of the main body 10 so as to cover the lower surface opening portion 11 and the opening portion 2 of the ceiling 1.

本体１０の内部中央には、室内空気の送風のための送風装置１２が設置され、送風装置１２の周りには空気を冷却したり加熱したりする熱交換器１３が設置される。そして、天井パネル２０には、中央に吸入口２１が形成され、吸入口２１の周りの四方に吐出口２２が形成される。また、吸入口２１側には多数の通穴２３ａが開いた吸入グリル２３が設置される。   A blower 12 for blowing indoor air is installed in the center of the main body 10, and a heat exchanger 13 for cooling and heating the air is installed around the blower 12. In the ceiling panel 20, an inlet 21 is formed at the center, and discharge ports 22 are formed in four directions around the inlet 21. A suction grille 23 having a large number of through holes 23a is provided on the suction port 21 side.

送風装置１２は、下部の吸入口２１側から空気を吸い込んで半径方向に吐出させる遠心型ターボファン１２ａと、このターボファン１２ａを駆動するように本体１０の奥側上面に固定される駆動モーター１２ｂとを含む。熱交換器１３は、ターボファン１２ａの動作により送り出される空気が通過しつつ熱交換されるように、ターボファン１２ａの周りの四方に設置される。また、熱交換器１３は、熱交換器１３から流れる凝縮水を集めて排出するように、本体１０の内側下部に設置される支持部材１４により支持される。また、支持部材１４には、ターボファン１２ａの入口側とターボファン１２ａの出口側の空間とを区画して空気流れを円滑にする空気案内板１５が設置される。これによれば、本体１０内部の送風装置１２が動作するときに、吸入口２１から本体１０の内部に吸入された空気が、熱交換器１３を通過しながら熱交換された後に吐出口２２を通して再び室内空間に供給され、室内空間の冷房または暖房がなされることができる。   The blower 12 includes a centrifugal turbo fan 12a that sucks air from the lower suction port 21 side and discharges it in the radial direction, and a drive motor 12b that is fixed to the upper surface on the back side of the main body 10 so as to drive the turbo fan 12a. Including. The heat exchanger 13 is installed in four directions around the turbo fan 12a so that the air sent out by the operation of the turbo fan 12a exchanges heat while passing. In addition, the heat exchanger 13 is supported by a support member 14 installed at the inner lower portion of the main body 10 so as to collect and discharge the condensed water flowing from the heat exchanger 13. The support member 14 is provided with an air guide plate 15 that partitions the space on the inlet side of the turbo fan 12a and the space on the outlet side of the turbo fan 12a to smooth the air flow. According to this, when the air blower 12 inside the main body 10 operates, the air sucked into the main body 10 from the suction port 21 is subjected to heat exchange while passing through the heat exchanger 13 and then passed through the discharge port 22. It is supplied to the indoor space again, and the indoor space can be cooled or heated.

また、本発明に従う天井型空気調和機は、冬期暖房運転を遂行するに際して熱交換器１３による暖房が充分でない場合に、吐出口２２を通して室内に供給される空気をさらに加熱するために四方の各吐出口２２に設置される補助ヒーター３１，３２と、この補助ヒーター３１，３２を支持するために各吐出口２２の内側に設置されるヒーター支持部材３３，３４，３５とを含む。   In addition, the ceiling type air conditioner according to the present invention has four sides to further heat the air supplied to the room through the discharge port 22 when the heating by the heat exchanger 13 is insufficient when performing the winter heating operation. Auxiliary heaters 31 and 32 installed at the discharge ports 22 and heater support members 33, 34 and 35 installed inside the discharge ports 22 to support the auxiliary heaters 31 and 32 are included.

補助ヒーターは、図２ないし図４に示すように、吐出口２２を通過する空気と熱交換を通じて吐出空気を加熱するように、四方の各吐出口２２内に設置される。また、この補助ヒーターは、各吐出口２２内において各吐出口２２の長手方向に連続して配置される所定長さの第１のヒーター３１と第２のヒーター３２とからなる。ここで、各補助ヒーター３１，３２は、電源の印加によって発熱する棒形状の発熱部と、この発熱部に結合される多数の熱交換フィンとを含む。   As shown in FIGS. 2 to 4, the auxiliary heater is installed in each of the four discharge ports 22 so as to heat the discharge air through heat exchange with the air passing through the discharge ports 22. The auxiliary heater includes a first heater 31 and a second heater 32 having a predetermined length that are continuously arranged in the longitudinal direction of each discharge port 22 in each discharge port 22. Here, each of the auxiliary heaters 31 and 32 includes a rod-shaped heat generating portion that generates heat when a power source is applied, and a large number of heat exchange fins coupled to the heat generating portion.

ヒーター支持部材３３，３４，３５は、吐出口２２の一側に設置されて第１のヒーター３１の一端を支持する第１のヒーター支持部材３３と、吐出口２２の他側に設置されて第２のヒーター３２の一端を支持する第２のヒーター支持部材３４と、吐出口２２の中央部に設置されて第１及び第２のヒーター３１，３２を同時に支持する第３のヒーター支持部材３５とを含む。このように、短い長さをもつ第１及び第２のヒーターを備え、該二つのヒーター３１，３２を各吐出口ごとに連続して設置し、かつ、第１及び第２のヒーター３１，３２が、第１及び第２のヒーター支持部材３３，３４のみならず、吐出口２２の中央に設けられた第３のヒーター支持部材３５に支持されるようにすれば、ヒーターの長さを長くする場合に熱変形により生じるヒーターの垂れを防ぐことが可能になる。このとき、ヒーター支持部材３３，３４，３５は、電気絶縁性と耐熱性に優れたセラミックのような材質からなる。   The heater support members 33, 34, and 35 are installed on one side of the discharge port 22 and are installed on the other side of the discharge port 22 and the first heater support member 33 that supports one end of the first heater 31. A second heater support member 34 that supports one end of the second heater 32, and a third heater support member 35 that is installed at the center of the discharge port 22 and supports the first and second heaters 31 and 32 simultaneously. including. Thus, the first and second heaters having a short length are provided, the two heaters 31 and 32 are continuously installed for each discharge port, and the first and second heaters 31 and 32 are provided. However, if it is supported not only by the first and second heater support members 33 and 34 but also by the third heater support member 35 provided at the center of the discharge port 22, the length of the heater is increased. In this case, it is possible to prevent the heater from dripping caused by thermal deformation. At this time, the heater support members 33, 34, and 35 are made of a material such as ceramic having excellent electrical insulation and heat resistance.

また、本発明は、熱交換器１３を通過した後に各吐出口２２側に流れる空気の流動抵抗を減らすために、各吐出口２２の第３のヒーター支持部材３５と一体に設けられる空気案内部４０を含む。この空気案内部４０は、図３及び図４に示すように、第３のヒーター支持部材３５の上部から空気の流動方向と対向する方向に突設される。すなわち、空気案内部４０は、その頂点４１が空気の流動方向と対向するように第３のヒーター支持部材３５の垂直二等分線(Ａ)から空気の流動方向と対向する方向に所定角度(θ)だけ傾斜した方向に突出される。また、空気案内部４０は、空気の流動抵抗を最小化するためにその先端部と外面が流線型の曲面をなす。   In addition, the present invention provides an air guide unit that is provided integrally with the third heater support member 35 of each discharge port 22 in order to reduce the flow resistance of the air that flows to each discharge port 22 side after passing through the heat exchanger 13. 40 is included. As shown in FIGS. 3 and 4, the air guide portion 40 protrudes from the upper portion of the third heater support member 35 in a direction opposite to the air flow direction. That is, the air guide portion 40 has a predetermined angle (in the direction facing the air flow direction from the perpendicular bisector (A) of the third heater support member 35 so that the apex 41 faces the air flow direction. It protrudes in a direction inclined by θ). In addition, the air guide portion 40 has a streamlined curved surface at its tip and outer surface in order to minimize air flow resistance.

このような空気案内部４０は、ターボファン１２ａの動作によりターボファン１２ａの回転方向に旋回しつつ送り出される空気の流動特性に鑑みてなされたものであり、吐出口２２側に送風される空気が、吐出口２２内に円滑に案内されるようにすることによって、空気の流動抵抗を減らすためのものである。   Such an air guide 40 is made in view of the flow characteristics of the air sent out while turning in the rotation direction of the turbo fan 12a by the operation of the turbo fan 12a, and the air blown to the discharge port 22 side is made. The air flow resistance is reduced by smoothly guiding into the discharge port 22.

すなわち、本発明に従う天井型空気調和機は、ターボファン１２ａの動作により送り出される空気が、図２及び図３に示すように、ターボファン１２ａの回転方向に向かう円周方向成分(ｕ)と半径方向成分(ｗ)の影響からターボファン１２ａの半径方向に送風されると同時に、ターボファンの回転方向に旋回しつつ流動する。また、この空気は、熱交換器１３を通過した後にも旋回し続きながら吐出口２２側に流動する。したがって、熱交換器１３を経て四方の各吐出口２２に流れる空気は、旋回しつつある状態であり、なおかつ送風方向が吐出口２２の方向と一致しないため、吐出口２２に至っては流動抵抗が大きくなるが、本発明では、このような空気が、空気案内部４０の案内により吐出口２２側に円滑に流入するので、流動抵抗が低減するようになる。   That is, in the ceiling type air conditioner according to the present invention, as shown in FIGS. 2 and 3, the air sent out by the operation of the turbo fan 12a has a circumferential component (u) and a radius in the direction of rotation of the turbo fan 12a. Due to the influence of the direction component (w), the air is blown in the radial direction of the turbo fan 12a, and at the same time, it flows while swirling in the rotational direction of the turbo fan. Further, the air flows toward the discharge port 22 while continuing to swirl after passing through the heat exchanger 13. Therefore, the air flowing through the heat exchanger 13 to the four discharge ports 22 is in a state of turning, and the air blowing direction does not coincide with the direction of the discharge ports 22, so that the flow resistance reaches the discharge ports 22. However, in the present invention, such air smoothly flows into the discharge port 22 side by the guidance of the air guide portion 40, so that the flow resistance is reduced.

また、この空気案内部４０は、吐出口２２を通過する空気の流動抵抗を減らして第３のヒーター支持部材３５と吐出空気との干渉を抑えるので、夏期冷房運転のときに第３のヒーター支持部材３５での結露現象を防ぐことができる。   Further, the air guide 40 reduces the flow resistance of the air passing through the discharge port 22 and suppresses the interference between the third heater support member 35 and the discharge air, so that the third heater support is supported during the summer cooling operation. The dew condensation phenomenon on the member 35 can be prevented.

本発明に従う天井型空気調和機によれば、第の３ヒーター支持部材から突出する空気案内部により、吐出口側に送り出される空気が吐出口の内部に円滑に案内されるので、吐出口を通過する空気の流動抵抗を低減することができるという効果が得られる。   According to the ceiling type air conditioner according to the present invention, the air guided to the discharge port side is smoothly guided to the inside of the discharge port by the air guide portion protruding from the third heater support member, so that it passes through the discharge port. The effect of reducing the flow resistance of the air is obtained.

また、本発明によれば、空気案内部の送風案内により吐出空気とヒーター支持部材間の干渉が低減するので、夏期冷房運転のときにヒーター支持部材で発生する結露現象を防ぐことが可能になる。   In addition, according to the present invention, since the air guide guides the air flow to reduce interference between the discharged air and the heater support member, it is possible to prevent the dew condensation phenomenon that occurs in the heater support member during the summer cooling operation. .
