ここで、天井埋込型空気調和機１００の空気調和機能を実現する冷凍サイクルについて説明する。図５は天井埋込型空気調和機１００の冷凍サイクルを示す概略図である。天井埋込型空気調和機１００の冷凍サイクルは、ユニット本体１及び圧縮機５１０、四方弁５２０、室外熱交換器５３０及び膨張弁５４０を有している室外機５００にて構成されている。ユニット本体１は室外機５００とガス冷媒配管６００、液冷媒配管７００により配管接続され、冷凍サイクルを構成する。 Here, a refrigeration cycle that realizes the air conditioning function of the ceiling-embedded air conditioner 100 will be described. FIG. 5 is a schematic view showing a refrigeration cycle of the ceiling-embedded air conditioner 100. The refrigeration cycle of the ceiling-embedded air conditioner 100 includes a unit main body 1, a compressor 510, a four-way valve 520, an outdoor heat exchanger 530, and an outdoor unit 500 having an expansion valve 540. The unit main body 1 is connected to the outdoor unit 500 by a gas refrigerant pipe 600 and a liquid refrigerant pipe 700 to form a refrigeration cycle.

圧縮機５１０は、吸入した冷媒を圧縮して吐出する。ここで、特に限定するものではないが、圧縮機５１０はたとえばインバータ回路等により、運転周波数を任意に変化させ、圧縮機５１０の容量を変化させるものなどでよい。ここで、圧縮機５１０の容量とは、単位時間あたりの冷媒を送り出す量を示す。四方弁５２０は、たとえば冷房運転時と暖房運転時とによって冷媒の流れを切り換えるための弁である。 The compressor 510 compresses and discharges the sucked refrigerant. Here, although not particularly limited, the compressor 510 may be one that arbitrarily changes the operating frequency and changes the capacity of the compressor 510 by, for example, an inverter circuit or the like. Here, the capacity of the compressor 510 indicates the amount of refrigerant delivered per unit time. The four-way valve 520 is a valve for switching the flow of the refrigerant between, for example, a cooling operation and a heating operation.

室外熱交換器５３０は、冷媒と室外の空気との熱交換を行う。たとえば、暖房運転時においては蒸発器として機能し、冷媒を蒸発させ、気化させる。また、冷房運転時においては凝縮器として機能し、冷媒を凝縮して液化させる。 The outdoor heat exchanger 530 exchanges heat between the refrigerant and the outdoor air. For example, it functions as an evaporator during heating operation to evaporate and vaporize the refrigerant. In addition, it functions as a condenser during cooling operation to condense and liquefy the refrigerant.

膨張弁５４０は冷媒を減圧して膨張させるものであり、絞り装置、流量制御手段等から構成される。たとえば電子式膨張弁等で構成した場合には、図示しない制御手段等の指示に基づいて開度調整を行う。 The expansion valve 540 decompresses and expands the refrigerant, and is composed of a throttle device, a flow rate control means, and the like. For example, when it is composed of an electronic expansion valve or the like, the opening degree is adjusted based on an instruction of a control means or the like (not shown).

ユニット本体１における冷房運転について冷媒の流れに基づいて説明する。冷房運転においては、圧縮機５１０により圧縮されて吐出した高温、高圧のガス冷媒が四方弁５２０を通過し、室外熱交換器５３０に流入する。そして、室外熱交換器５３０内を通過して、室外の空気と熱交換することで凝縮、液化した冷媒である液冷媒は、膨張弁５４０へ流入する。膨張弁５４０で減圧されて気液二相状態となった冷媒は室外機５００から流出する。 The cooling operation in the unit main body 1 will be described based on the flow of the refrigerant. In the cooling operation, the high-temperature, high-pressure gas refrigerant compressed and discharged by the compressor 510 passes through the four-way valve 520 and flows into the outdoor heat exchanger 530. Then, the liquid refrigerant, which is a refrigerant condensed and liquefied by passing through the outdoor heat exchanger 530 and exchanging heat with the outdoor air, flows into the expansion valve 540. The refrigerant that has been decompressed by the expansion valve 540 and is in a gas-liquid two-phase state flows out from the outdoor unit 500.

室外機５００を流出した気液二相冷媒は、液冷媒配管７００を通過してユニット本体１に流入し、室内熱交換器５５を通過する。そして、室内熱交換機５５を通る空気と熱交換することで蒸発、ガス化した冷媒であるガス冷媒は、ユニット本体１から流出する。 The gas-liquid two-phase refrigerant flowing out of the outdoor unit 500 passes through the liquid refrigerant pipe 700, flows into the unit main body 1, and passes through the indoor heat exchanger 55. Then, the gas refrigerant, which is a refrigerant vaporized and gasified by exchanging heat with the air passing through the indoor heat exchanger 55, flows out from the unit main body 1.

ユニット本体１から流出したガス冷媒はガス冷媒配管６００を通過して室外機５００に流入する。そして、四方弁５２０を通過して再度圧縮機５１０に吸入される。以上のようにしてユニット本体１の冷媒が循環し、空気調和による冷房を行う。 The gas refrigerant flowing out from the unit main body 1 passes through the gas refrigerant pipe 600 and flows into the outdoor unit 500. Then, it passes through the four-way valve 520 and is sucked into the compressor 510 again. As described above, the refrigerant of the unit main body 1 circulates and cools by air conditioning.

上記の冷凍サイクルによってユニット本体１が室内空気の冷房を行うとき、室内熱交換機５５を通過し、室内熱交換機５５と熱交換することにより冷やされた空気が吹出口８から室内に吹出され、室内の空気温度を冷却する。このとき、ユニット本体１の冷房により室内側の空気温度と天井裏側の空気温度に温度差が発生する。室内側の空気温度と天井裏側の空気温度の差が大きく、天井裏側の空気温度が室内側より高い場合、天井裏側の高温高湿の空気がパネル６の開口１４を通じてパネル６とカバー７の間に流れ込むと、カバー７の裏面１６ｂ（図６（ｂ）を参照）及び化粧パネル２の側面に結露が生じる問題がある。本発明はこのようなカバー７の裏面１６ｂ及び化粧パネル２の側面に生じる結露を抑制するものである。以下、結露を抑制するためにパネル６とカバー７に設けられる構造に関して述べる。 When the unit body 1 cools the indoor air by the above refrigeration cycle, the air cooled by passing through the indoor heat exchanger 55 and exchanging heat with the indoor heat exchanger 55 is blown into the room from the air outlet 8 to enter the room. Cool the air temperature. At this time, the cooling of the unit main body 1 causes a temperature difference between the air temperature on the indoor side and the air temperature on the ceiling back side. When the difference between the air temperature on the indoor side and the air temperature on the back side of the ceiling is large and the air temperature on the back side of the ceiling is higher than that on the indoor side, the hot and humid air on the back side of the ceiling passes between the panel 6 and the cover 7 through the opening 14 of the panel 6. There is a problem that dew condensation occurs on the back surface 16b of the cover 7 (see FIG. 6B) and the side surface of the decorative panel 2 when flowing into the air. The present invention suppresses dew condensation that occurs on the back surface 16b of the cover 7 and the side surface of the decorative panel 2.

図８（ａ）はカバー７をパネル６に取り付ける直前のパネル６に対するカバー７の位置を示した断面図である。最初に、カバー７を、パネル６の角部から空気吸込口４１に向かう方向にスライドさせる。その際、第１の外側リブ１５ａと第２の内側リブ１７ｂとが当たらないように、カバー７をベース部２６の領域３８ａに対し角度をつけながらスライドさせて、カバー７の３か所のフック１８ａ、１８ｂ及び１８ｃをそれぞれ対応するパネル６の留め具２７ａ、２７ｂ及び２７ｃに係合させる。その後、ネジ３４をネジ穴３５に通してカバー７の固定部１９ｂとパネル６とを固定する。以上の取り付けによりパネル６にカバー７が設置され、化粧パネル２が構成される。Next, a method of attaching the cover 7 to the panel 6 will be described with reference to FIGS. 8 (a) and 8 (b).
FIG. 8A is a cross-sectional view showing the position of the cover 7 with respect to the panel 6 immediately before the cover 7 is attached to the panel 6. First, the cover 7 is slid from the corner of the panel 6 toward the air suction port 41. At that time, the cover 7 is slid at an angle with respect to the region 38a of the base portion 26 so that the first outer rib 15a and the second inner rib 17b do not come into contact with each other, and the three hooks of the cover 7 are hooked. The 18a, 18b and 18c are engaged with the corresponding panel 6 fasteners 27a, 27b and 27c, respectively. After that, the screw 34 is passed through the screw hole 35 to fix the fixing portion 19b of the cover 7 and the panel 6. With the above attachment, the cover 7 is installed on the panel 6 to form the decorative panel 2.

図８（ｂ）はパネル６にカバー７を取り付けた後の、パネル６に対するカバー７の位置を示した断面図である。
カバー７は、遮蔽部１６に設けられたフック１８ａ、１８ｂ及び１８ｃがそれぞれパネル６の留め具２７ａ、２７ｂ及び２７ｃに係合し、固定部１９ｂがネジ３４によりパネル６に固定されることでパネル６に固定される。カバー７は、パネル６に取り付けると、遮蔽部１６の２辺２０ｃ及び２０ｄがそれぞれパネル６の外周の２辺３０ａ及び３０ｂに沿う位置に固定される。また、カバー７の遮蔽部１６の２辺２０ａ及び２０ｂは、それぞれパネル６に設けられた段差部２８ａ及び２８ｂの側壁部３１ａ及び３１ｂと突き当てられて固定される。FIG. 8B is a cross-sectional view showing the position of the cover 7 with respect to the panel 6 after the cover 7 is attached to the panel 6.
The cover 7 is a panel in which hooks 18a, 18b and 18c provided on the shielding portion 16 engage with fasteners 27a, 27b and 27c of the panel 6, respectively, and the fixing portion 19b is fixed to the panel 6 by screws 34. It is fixed at 6. When the cover 7 is attached to the panel 6, the two sides 20c and 20d of the shielding portion 16 are fixed at positions along the two sides 30a and 30b on the outer periphery of the panel 6, respectively. Further, the two sides 20a and 20b of the shielding portion 16 of the cover 7 are abutted against and fixed to the side wall portions 31a and 31b of the stepped portions 28a and 28b provided on the panel 6, respectively.

実施の形態１に示された化粧パネル２では、パネル６のベース部２６とカバー７の遮蔽部１６との間に、開口１４から第１のリブ１５と第２のリブ１７により隔離された略密閉の空気層３６ａ及び３６ｂが形成される。すなわち、リブ１５とリブ１７により、天井裏の高温高湿の空気が、開口１４を通じて空気層３６ａ及び３６ｂに流れ込むことが抑制される。これにより、化粧パネル２の天井裏側の空間と室内側の空間の温度差が大きく天井裏側の空間のほうが高温高湿である場合に天井埋込型空気調和機１００を使用する場合でも、カバー７の遮蔽部１６の裏面１６ｂ及び化粧パネル２の側面への結露の発生を抑えることができる。また、遮蔽部１６の裏面１６ｂ及び化粧パネル２の側面への結露の発生を抑えることにより、パネル６のベース部２６とカバー７の遮蔽部１６との接続部から結露による水滴が室内にしたたり落ちるのを抑えることができる。また、天井裏の高温高湿の空気が、開口１４を通じて空気層３６ｂに流れ込むことが抑制されるので、空気層３６ｂ内に設けられたモータ１１と、軸１０への結露の発生を抑えることができる。 In the decorative panel 2 shown in the first embodiment, the base portion 26 of the panel 6 and the shielding portion 16 of the cover 7 are separated from the opening 14 by a first rib 15 and a second rib 17. Sealed air layers 36a and 36b are formed. That is, the ribs 15 and 17 suppress the high-temperature and high-humidity air behind the ceiling from flowing into the air layers 36a and 36b through the openings 14. As a result, even when the ceiling-embedded air conditioner 100 is used when the temperature difference between the space behind the ceiling and the space inside the room of the decorative panel 2 is large and the space behind the ceiling is hotter and humider, the cover 7 is used. It is possible to suppress the occurrence of dew condensation on the back surface 16b of the shielding portion 16 and the side surface of the decorative panel 2. Further, by suppressing the occurrence of dew condensation on the back surface 16b of the shielding portion 16 and the side surface of the decorative panel 2, water droplets due to dew condensation may be allowed to enter the room from the connection portion between the base portion 26 of the panel 6 and the shielding portion 16 of the cover 7. It can be prevented from falling. Further, since the high temperature and high humidity air behind the ceiling is suppressed from flowing into the air layer 36b through the opening 14, it is possible to suppress the occurrence of dew condensation on the motor 11 provided in the air layer 36b and the shaft 10. can.

実施の形態１に示された化粧パネル２では、カバー７の遮蔽部１６に第２の外側リブ１７ａと、第２の外側リブ１７ａより遮蔽部１６からの高さが低い第２の内側リブ１７ｂを設ける。この構造は、第２の内側リブ１７ｂの遮蔽部１６からの高さが第２の外側リブ１７ａと等しい場合と比べて、第１の外側リブ１５ａに設ける第２の内側リブ１７ｂを納めるための溝３３の深さが浅い。すなわち、第１の外側リブ１５ａの溝３３が設けられる領域において、第１の外側リブ１５ａと第２の外側リブ１７ａが当接する領域４３が大きい。よって、第２の内側リブ１７ｂの遮蔽部１６からの高さが第２の外側リブ１７ａと等しい場合と比べて、ベース部２６と遮蔽部１６間の、リブ１５とリブ１７とで開口１４から隔離される空気層３６ａ及び３６ｂの密閉性を高めることができる。 In the decorative panel 2 shown in the first embodiment, the shielding portion 16 of the cover 7 has a second outer rib 17a and a second inner rib 17b whose height from the shielding portion 16 is lower than that of the second outer rib 17a. Is provided. This structure accommodates the second inner rib 17b provided on the first outer rib 15a as compared with the case where the height of the second inner rib 17b from the shielding portion 16 is equal to the second outer rib 17a. The depth of the groove 33 is shallow. That is, in the region where the groove 33 of the first outer rib 15a is provided, the region 43 where the first outer rib 15a and the second outer rib 17a abut is large. Therefore, as compared with the case where the height of the second inner rib 17b from the shielding portion 16 is equal to that of the second outer rib 17a, the rib 15 and the rib 17 between the base portion 26 and the shielding portion 16 are opened from the opening 14. The airtightness of the isolated air layers 36a and 36b can be enhanced.

また、実施の形態１に示された化粧パネル２では、カバー７の結露対策として、断熱材などの追加の部材を必要としない。そのため、従来の閉鎖カバー裏面の結露対策のような追加部品が不要となる。結果、部品点数の増加に伴う工程数の増加や、化粧パネルの重量増加を抑えることができる。 Further, the decorative panel 2 shown in the first embodiment does not require an additional member such as a heat insulating material as a measure against dew condensation on the cover 7. Therefore, there is no need for additional parts such as the conventional measures against dew condensation on the back surface of the closing cover. As a result, it is possible to suppress an increase in the number of processes and an increase in the weight of the decorative panel due to an increase in the number of parts.

実施の形態２．
この発明の実施の形態２の化粧パネル２００について図９及び図１０を用いて説明する。なお、図９及び図１０中、図７及び図８と同一符号は同一部分を指す。この実施の形態２の化粧パネル２００は、実施の形態１の第１の外側リブ１５ａ及び第１の内側リブ１５ｂに替えて、ベース部２６上に第１の内側リブ５０ｂと、ベース部２６からの高さが第１の内側リブ５０ｂより低い第１の外側リブ５０ａを設けるように構成したものである。Embodiment 2.
The decorative panel 200 according to the second embodiment of the present invention will be described with reference to FIGS. 9 and 10. In FIGS. 9 and 10, the same reference numerals as those in FIGS. 7 and 8 refer to the same parts. The decorative panel 200 of the second embodiment replaces the first outer rib 15a and the first inner rib 15b of the first embodiment with the first inner rib 50b on the base portion 26 and the base portion 26. The height of the first outer rib 50a is lower than that of the first inner rib 50b.

実施の形態２に示された化粧パネル２００は、第１の内側リブ５０ｂよりベース部２６の領域３９ａからの高さが低い第１の外側リブ５０ａを設けることで、第１の外側リブ５０ａのベース部２６の領域３９ａからの高さが第１の内側リブ５０ｂと等しい場合と比べて、第１の外側リブ５０ａに対して第２の内側リブ１７ｂをより近づけられるようになる。すなわち、遮蔽部１６をベース部２６に近づけるときの、ベース部２６の領域３９ａに対する遮蔽部基準面４７の角度を平行に近づけることができる。よって、ベース部２６の領域３９ａに対する係受部３８の角度θをゼロ（領域３９ａと略平行）に近づけることができる。このような構造により、化粧パネル２をユニット本体１に取り付けた状態における、留め具２７ａ、２７ｂ及び２７ｃのフック１８ａ、１８ｂ及び１８ｃを天井面に略垂直な方向に対して固定する機能が向上する。よって、実施の形態１の効果に加え、パネル６のカバー７に対する天井面に略垂直な方向の係合能力を高めることができる。 The decorative panel 200 shown in the second embodiment is provided with the first outer rib 50a having a height lower than the first inner rib 50b from the region 39a of the base portion 26, whereby the first outer rib 50a is provided. The second inner rib 17b can be brought closer to the first outer rib 50a as compared with the case where the height of the base portion 26 from the region 39a is equal to the first inner rib 50b. That is, when the shielding portion 16 is brought closer to the base portion 26, the angle of the shielding portion reference surface 47 with respect to the region 39a of the base portion 26 can be brought closer to parallel. Therefore, the angle θ of the engaging portion 38 with respect to the region 39a of the base portion 26 can be brought close to zero (substantially parallel to the region 39a). With such a structure, the function of fixing the hooks 18a, 18b and 18c of the fasteners 27a, 27b and 27c in the state where the decorative panel 2 is attached to the unit body 1 in a direction substantially perpendicular to the ceiling surface is improved. .. Therefore, in addition to the effect of the first embodiment, the engagement ability of the panel 6 with respect to the cover 7 in the direction substantially perpendicular to the ceiling surface can be enhanced.

実施の形態３．
この発明の実施の形態３の化粧パネル３００について図１１、図１２及び図１３を用いて説明する。なお、図１１、図１２及び図１３中、図３、図７及び図８と同一符号は同一部分を指す。この実施の形態３の化粧パネル３００は、実施の形態１の第１の外側リブ１５ａ及び第２の内側リブ１５ｂに替えて、ベース部２６に第１の外側リブ６０ａを設け、遮蔽部１６に第２の内側リブ６０ｂを設ける。第１の外側リブ６０ａのベース部２６の領域３９ａからの高さＬ１が、領域３９ａから第２の内側リブ６０ｂの先端までの距離Ｌ２より低い点で実施の形態１と異なる。また、実施の形態３では第１の外側リブ１５ａに溝３３が設けられていない。Embodiment 3.
The decorative panel 300 according to the third embodiment of the present invention will be described with reference to FIGS. 11, 12, and 13. In FIGS. 11, 12, and 13, the same reference numerals as those in FIGS. 3, 7, and 8 refer to the same parts. In the decorative panel 300 of the third embodiment, the base portion 26 is provided with the first outer rib 60a instead of the first outer rib 15a and the second inner rib 15b of the first embodiment, and the shielding portion 16 is provided with the first outer rib 60a. A second inner rib 60b is provided. The height L1 of the base portion 26 of the first outer rib 60a from the region 39a is lower than the distance L2 from the region 39a to the tip of the second inner rib 60b, which is different from the first embodiment. Further, in the third embodiment, the groove 33 is not provided in the first outer rib 15a.

実施の形態３に示された化粧パネル３００は、第１の外側リブ６０ａのベース部２６の領域３９ａからの高さＬ１が、ベース部２６の領域３９ａから第２の内側リブ６０ｂの先端までの距離Ｌ２より低くなるよう第１の外側リブ６０ａと第２の内側リブ６０ｂを設ける。第１の外側リブ６０ａのベース部２６の領域３９ａからの高さＬ１が、ベース部２６の領域３９ａから第２の内側リブ６０ｂの先端までの距離Ｌ２より低いので、遮蔽部１６をベース部２６の領域３９ａに対して平行に移動させてカバー７をパネル６に取り付けることができる。すなわち、ベース部２６の留め具２７ａ、２７ｂ及び２７ｃにおける係受部３８の角度をベース部２６の領域３９ａと略平行（≒０）に設けることができる。このような構造により、化粧パネル２をユニット本体１に取り付けた状態における、留め具２７ａ、２７ｂ及び２７ｃのフック１８ａ、１８ｂ及び１８ｃを天井面に略垂直な方向に対して固定する機能が向上し、実施の形態１の効果に加え、パネル６のカバー７に対する天井面に略垂直な方向の係合能力を高めることができる。 In the decorative panel 300 shown in the third embodiment, the height L1 of the first outer rib 60a from the region 39a of the base portion 26 is from the region 39a of the base portion 26 to the tip of the second inner rib 60b. The first outer rib 60a and the second inner rib 60b are provided so as to be lower than the distance L2. Since the height L1 of the first outer rib 60a from the region 39a of the base portion 26 is lower than the distance L2 from the region 39a of the base portion 26 to the tip of the second inner rib 60b, the shielding portion 16 is used as the base portion 26. The cover 7 can be attached to the panel 6 by moving it in parallel with the region 39a. That is, the angle of the engaging portion 38 in the fasteners 27a, 27b and 27c of the base portion 26 can be provided substantially parallel (≈0) with the region 39a of the base portion 26. With such a structure, the function of fixing the hooks 18a, 18b and 18c of the fasteners 27a, 27b and 27c in the state where the decorative panel 2 is attached to the unit body 1 in a direction substantially perpendicular to the ceiling surface is improved. In addition to the effect of the first embodiment, the engagement ability of the panel 6 with respect to the cover 7 in a direction substantially perpendicular to the ceiling surface can be enhanced.

実施の形態３に示された化粧パネル３００では、遮蔽部１６をベース部２６の領域３９ａに対して平行に移動させてカバー７をパネル６に取り付けることができるため、図１１に示すように、ベース部２６の壁部２９ａと２９ｂの代わりに、固定部１９ｂを通すための固定部用開口４４を有する壁部４５をベース部２６上に設けることができる。 In the decorative panel 300 shown in the third embodiment, the cover 7 can be attached to the panel 6 by moving the shielding portion 16 in parallel with the region 39a of the base portion 26, as shown in FIG. Instead of the wall portions 29a and 29b of the base portion 26, a wall portion 45 having a fixing portion opening 44 for passing the fixing portion 19b can be provided on the base portion 26.

また、本発明は、上記各実施形態に限定されるものではなく、その要旨を逸脱しない範囲において、適宜変形が可能である。例えば、上記実施形態では、第２の内側リブ１７ｂは、第２の外側リブ１７ａより遮蔽部基準面４７からの高さが低くなるように形成されているが、第１のリブ１５と第２のリブ１７の形状は限定されるものではなく、カバー７をパネル６に取り付けたときに、第１のリブ１５と第２のリブ１７とが当接し、遮蔽部１６、ベース２６、第１のリブ１５及び第２のリブ１７により開口１４から隔離された略密閉の空気層３６ａ及び３６ｂが形成される限りにおいて、その他の形状に変更が可能である。 Further, the present invention is not limited to each of the above embodiments, and can be appropriately modified as long as the gist of the present invention is not deviated. For example, in the above embodiment, the second inner rib 17b is formed so that the height from the shielding portion reference surface 47 is lower than that of the second outer rib 17a, but the first rib 15 and the second rib 17b are formed. The shape of the rib 17 is not limited, and when the cover 7 is attached to the panel 6, the first rib 15 and the second rib 17 come into contact with each other, and the shielding portion 16, the base 26, and the first rib 17 come into contact with each other. Other shapes can be changed as long as the substantially sealed air layers 36a and 36b separated from the opening 14 by the ribs 15 and the second ribs 17 are formed.
