Description

本発明は、板金で構成された外郭部材の内部に、発泡スチロール製の断熱部材を設置した天井埋込形空気調和機に関するものである。   The present invention relates to a ceiling-embedded air conditioner in which an insulating member made of expanded polystyrene is installed inside an outer member made of sheet metal.

従来は、板金で構成された外郭部材の内部に発泡スチロール製の断熱部材を設置した空気調和機の吹出チャンバにおいて、断熱部材が外郭部材と接触する面の周縁部に凸状の突起部を設けていた（例えば、特許文献１参照）。   Conventionally, in a blowout chamber of an air conditioner in which a heat insulating member made of polystyrene foam is installed inside an outer member made of sheet metal, a convex protrusion is provided on the peripheral edge of the surface where the heat insulating member contacts the outer member. (For example, see Patent Document 1).

特開２００６−２９６３０号公報（第４―５頁、図５）Japanese Patent Laying-Open No. 2006-29630 (page 4-5, FIG. 5)

従来の空気調和機では、空調運転開始時などに急激な温度変化が生じた場合、板金と発泡スチロールの膨張率の違いにより両者の間で摩擦が生じ、特に温度変化が激しい熱交換器の周辺で、きしみ音が発生するという問題があった。   In a conventional air conditioner, when a sudden temperature change occurs at the start of air conditioning operation, etc., friction occurs between the two due to the difference in expansion coefficient between the sheet metal and the polystyrene foam, especially in the vicinity of a heat exchanger where the temperature changes drastically. There was a problem that squeak noise was generated.

本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、運転開始時などに発生するきしみ音を低減することができる天井埋込形空気調和機を提供することを第１の目的とする。また、追加部材がなくて済み、低コストできしみ音を低減することができる天井埋込形空気調和機を提供することを第２の目的とする。   The present invention has been made to solve the above-described problems, and has as its first object to provide a ceiling-embedded air conditioner that can reduce squeak noise generated at the start of operation. To do. Another object of the present invention is to provide a ceiling-embedded air conditioner that does not require additional members, can be produced at low cost, and can reduce squeak noise.

本発明に係る天井埋込形空気調和機は、板金で構成された外郭部材と、前記外郭部材内に設けられた熱交換器と、吸込み口から吸込んだ室内空気を前記熱交換器を通して吹出し口から吹出す送風機と、前記外郭部材と熱交換器の間に設けられた発泡スチロール製の断熱部材とを備え、前記断熱部材の前記外郭部材と対向する側の面であって前記熱交換器の上部に該熱交換器の形状に沿って截頭角錐状の突部を所望の間隔で点在させて一体成形し、前記突部を介して前記断熱部材と外郭部材を接触させたものである。 The ceiling-embedded air conditioner according to the present invention includes an outer member made of sheet metal, a heat exchanger provided in the outer member, and the indoor air sucked from the suction port through the heat exchanger. An air blower that blows out from the outer shell and a heat insulating member made of polystyrene foam provided between the outer member and the heat exchanger, and is a surface of the heat insulating member that faces the outer member, and is an upper portion of the heat exchanger Further, a truncated pyramid-shaped protrusion is scattered at a desired interval along the shape of the heat exchanger and integrally formed, and the heat insulating member and the outer member are brought into contact with each other through the protrusion.

本発明の天井埋込形空気調和機は、外郭の板金に接触する発泡スチロール製の断熱部材の表面に突部を設けたので、外郭部材と断熱部材の接触面積が小さくなり、運転開始時などの急激に温度が変化したとき、外郭部材と断熱部材の膨張率の差により生じるきしみ音を低減することができる。
また、本発明の天井埋込形空気調和機は、発泡スチロール製の断熱部材の表面形状を変更するだけで、突部は一体成形によって形成されるので、追加部材が必要なく、低コストできしみ音を低減させることができる。 In the ceiling-embedded air conditioner of the present invention, since the protrusion is provided on the surface of the heat insulating member made of foamed polystyrene that contacts the outer sheet metal, the contact area between the outer member and the heat insulating member is reduced, and the operation is started. When the temperature changes abruptly, it is possible to reduce squeak noise caused by the difference in expansion coefficient between the outer member and the heat insulating member.
In the ceiling-embedded air conditioner according to the present invention, the protrusion is formed by integral molding only by changing the surface shape of the heat insulating member made of foamed polystyrene. Can be reduced.

実施の形態１．
図１は本発明の実施の形態１にかかる天井埋込形空気調和機の縦断面図、図２は図１の外郭板金の天板を取り外した状態の上面図、図３は図１の断熱部材と外郭部材の接触部近傍を拡大した縦断面図である。
図１、図２に示すように、天井埋込形空気調和機は、その外郭に板金で形成された外郭部材１を有する。外郭部材１の内部には室内空気を循環させる送風機５が設けられており、この送風機５はモータ６によって回転する。また、送風機５を囲むようにしてほぼ四角形に配置された熱交換器３が設けられ、熱交換器３の下部には熱交換器３により除湿された水分を回収するドレンパン４が設けられている。さらに、外郭部材１の内側には、吸込口７と吹出口９を形成する化粧パネル８によって構成され、空気調和機の内部と外部を断熱するための発泡スチロール製の断熱部材２が設けられている。そして、断熱部材２の外郭部材１側の表面には、外郭部材１との接触面積を低減するためのほぼ半球状の突部２ａが、断熱部材２と一体に成形されて点在している。 Embodiment 1 FIG.
1 is a longitudinal sectional view of a ceiling-embedded air conditioner according to a first embodiment of the present invention, FIG. 2 is a top view of the outer sheet metal top plate of FIG. 1 removed, and FIG. 3 is the heat insulation of FIG. It is the longitudinal cross-sectional view which expanded the contact part vicinity of a member and an outer shell member.
As shown in FIGS. 1 and 2, the ceiling-embedded air conditioner has an outer member 1 formed of sheet metal on its outer shell. A blower 5 for circulating room air is provided inside the outer member 1, and the blower 5 is rotated by a motor 6. Further, a heat exchanger 3 arranged in a substantially square shape is provided so as to surround the blower 5, and a drain pan 4 for recovering moisture dehumidified by the heat exchanger 3 is provided at a lower portion of the heat exchanger 3. Furthermore, inside the outer shell member 1, a heat insulating member 2 made of styrene foam is provided, which is constituted by a decorative panel 8 that forms a suction port 7 and an air outlet 9, and insulates the inside and the outside of the air conditioner. . Then, on the surface of the heat insulating member 2 on the outer member 1 side, substantially hemispherical protrusions 2a for reducing the contact area with the outer member 1 are formed integrally with the heat insulating member 2 and scattered. .

この半球状の突部２ａは、図３に示すように、高さがＨ＝１ｍｍ〜５ｍｍであり、間隔がＬ１＝２０Ｈ〜４０Ｈ（高さＨの２０倍から４０倍）で、この突部２ａを介して断熱部材２が外郭部材１と接触するようになっている。この場合、突部２ａの高さＨが１ｍｍより小さいと、きしみ音の低減効果が小さく、逆に５ｍｍより大きいと、きしみ音の低減効果は変わらないものの室内機の外形が大きくなってしまう。よって、突部の高さは、Ｈ＝１〜５ｍｍの範囲であることが好ましい。また、突部２ａを、その高さＨの２０倍から４０倍の間隔Ｌ１で断熱部材２の表面に配置すると、断熱部材２と外郭部材１は突部２ａのみで接触し、その他の部分では隙間が生じて接触しないので、接触面積が小さくなり、空調運転開始時の急激な温度変化によるきしみ音の発生が低減できる。よって、突部２ａの間隔は、Ｌ１＝２０Ｈ〜４０Ｈの範囲であることが好ましい。   As shown in FIG. 3, the hemispherical protrusion 2a has a height of H = 1 mm to 5 mm and an interval of L1 = 20H to 40H (20 to 40 times the height H). The heat insulating member 2 comes into contact with the outer member 1 through 2a. In this case, if the height H of the protrusion 2a is smaller than 1 mm, the effect of reducing the squeaking noise is small. Conversely, if the height H is larger than 5 mm, the effect of reducing the squeaking noise does not change, but the outer shape of the indoor unit becomes large. Therefore, the height of the protrusion is preferably in the range of H = 1 to 5 mm. Further, when the protrusion 2a is arranged on the surface of the heat insulating member 2 at an interval L1 that is 20 to 40 times its height H, the heat insulating member 2 and the outer member 1 are in contact with each other only by the protrusion 2a. Since there is no gap and no contact occurs, the contact area is reduced, and the generation of squeak noise due to a rapid temperature change at the start of air conditioning operation can be reduced. Therefore, it is preferable that the space | interval of the protrusion 2a is the range of L1 = 20H-40H.

この突部２ａは断熱部材２の全面に点在しているが、部分的に点在した状態であってもよく、また熱交換器の周辺のみに点在した状態であってもよい。また、突部２ａはほぼ半球状に形成されているが、半球状に限定されるものではなく、例えばほぼ截頭角錐状であってもよく、あるいはほぼ截頭円錐状であってもよい。   The protrusions 2a are scattered over the entire surface of the heat insulating member 2, but may be partially scattered or may be scattered only around the heat exchanger. Further, the protrusion 2a is formed in a substantially hemispherical shape, but is not limited to a hemispherical shape, and may be, for example, a substantially truncated pyramid shape or a substantially truncated cone shape.

次に動作について説明する。
モータ６によって送風機５が回転すると、吸込口７から空気が吸い込まれ、冷媒配管１０を通じて冷媒が循環する熱交換器３で熱交換されて、吹出口９から吹出される。この場合、熱交換器３を通過した空気はその風路を形成する断熱部材２に沿って流れるので、断熱部材２には空調運転開始時に温度変化が生じ、冷房時は収縮し、暖房時は膨張する。一方、断熱部材２の外側の外郭部材１は、金属で構成されているので、発泡スチロールで形成されている断熱部材２に比べて、温度変化に対して膨張率が小さい。
このため、空気調和機の運転開始により温度変化が生じると、断熱部材２が外郭部材１にこすれてきしみ音が発生するおそれがあるが、上述のように断熱部材２の表面には、高さＨ＝１ｍｍ〜５ｍｍの突部２ａが、間隔Ｌ１＝２０Ｈ〜４０Ｈで断熱部材２と一体成形で形成され、この突部２ａと外郭部材１が接触するようになっているので、きしみ音が低減する。 Next, the operation will be described.
When the blower 5 is rotated by the motor 6, air is sucked from the suction port 7, heat is exchanged by the heat exchanger 3 in which the refrigerant circulates through the refrigerant pipe 10, and is blown from the blowout port 9. In this case, since the air that has passed through the heat exchanger 3 flows along the heat insulating member 2 that forms the air passage, the temperature of the heat insulating member 2 is changed at the start of the air-conditioning operation, and contracts during cooling and during heating. Inflate. On the other hand, since the outer shell member 1 outside the heat insulating member 2 is made of metal, it has a smaller expansion coefficient with respect to temperature change than the heat insulating member 2 formed of foamed polystyrene.
For this reason, when the temperature change occurs due to the start of the operation of the air conditioner, the heat insulating member 2 may be rubbed into the outer shell member 1 and a noise may be generated. However, as described above, the surface of the heat insulating member 2 has a height. The protrusion 2a with H = 1 mm to 5 mm is formed by integral molding with the heat insulating member 2 at a distance L1 = 20H to 40H, and the protrusion 2a and the outer member 1 are in contact with each other, so that squeak noise is reduced. To do.

本実施の形態１によれば、突部２ａにより外郭部材１と断熱部材２の接触面積が小さくなっているので、空調機の運転開始により急激に温度変化が生じても、外郭部材１と断熱部材２の膨張率の差によって生じるきしみ音を低減することができる。また、突部２ａが一体成形によって形成されるので、きしみ音の低減には追加部材が不要で、低コストで行うことが可能となる。   According to the first embodiment, since the contact area between the outer member 1 and the heat insulating member 2 is reduced by the protrusion 2a, the outer member 1 and the heat insulating member can be insulated from each other even if the temperature changes suddenly due to the start of operation of the air conditioner. The squeak noise generated by the difference in the expansion coefficient of the member 2 can be reduced. Moreover, since the protrusion 2a is formed by integral molding, an additional member is not necessary for reducing squeak noise, and it can be performed at low cost.

実施の形態２．
図４は本発明の実施の形態２にかかる天井埋込形空気調和機の縦断面図、図５は図４の外郭板金の天板を取り外した状態の上面図、図６は図４の断熱部材と外郭部材の接触部近傍を拡大した縦断面図である。実施の形態１では、断熱部材２の外郭部材１側の表面全体に突部２ａを点在させたが、本実施の形態２では熱交換器３の形状に沿って突部を点在させたものである。なお、実施の形態１と同一または相当部分には同一符号を付し、詳細な説明は省略する。 Embodiment 2. FIG.
4 is a longitudinal sectional view of a ceiling-embedded air conditioner according to a second embodiment of the present invention, FIG. 5 is a top view of the outer sheet metal top plate of FIG. 4 removed, and FIG. 6 is the heat insulation of FIG. It is the longitudinal cross-sectional view which expanded the contact part vicinity of a member and an outer shell member. In the first embodiment, the protrusions 2 a are scattered on the entire surface of the heat insulating member 2 on the outer member 1 side. However, in the second embodiment, the protrusions are scattered along the shape of the heat exchanger 3. Is. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and detailed description is abbreviate | omitted.

断熱部材２の表面には、外郭部材１との接触面積を低減するためのほぼ截頭角錐状の突部２ｂが、熱交換器３の形状に沿って熱交換器３の上部に所定の間隔で一体に成形されて点在している。この突部２ｂは、高さがＨ＝１ｍｍ〜５ｍｍで、外郭部材１との接触幅Ｌ２が熱交換器３側の幅Ｌ３の１／２以下となっており、この状態で断熱部材２と接触している。なお、突部２ｂの高さを１ｍｍ〜５ｍｍとする理由は実施の形態１の場合と同様である。   On the surface of the heat insulating member 2, a substantially truncated pyramid-shaped protrusion 2 b for reducing the contact area with the outer member 1 is arranged at a predetermined distance above the heat exchanger 3 along the shape of the heat exchanger 3. It is integrally molded with and scattered. This protrusion 2b is H = 1 mm to 5 mm in height, and the contact width L2 with the outer shell member 1 is ½ or less of the width L3 on the heat exchanger 3 side. In contact. The reason why the height of the protrusion 2b is 1 mm to 5 mm is the same as that in the first embodiment.

次に動作について説明する。
実施の形態１と同様に、断熱部材２は熱交換器３を通過した空気により温度変化を受けるが、特に熱交換器３と接触している付近はその他の部分に比べて、温度変化が大きくなる。このため、断熱部材２と外郭部材１が一様に接触している場合には、きしみ音の発生は熱交換器３の周辺が大きくなるおそれがあるが、上述したように、断熱部材２の表面には、高さＨ＝１ｍｍ〜５ｍｍであって、外郭部材１との接触幅Ｌ２が熱交換器３側の幅Ｌ３の１／２以下の突部２ｂが、断熱部材２と一体に成形され、この突部２ａと外郭部材１が接触するようになっているので、きしみ音が低減する。 Next, the operation will be described.
As in the first embodiment, the heat insulating member 2 undergoes a temperature change due to the air that has passed through the heat exchanger 3, but the temperature change is particularly large in the vicinity where the heat insulating member 2 is in contact with the heat exchanger 3 compared to other parts. Become. For this reason, when the heat insulating member 2 and the outer shell member 1 are in uniform contact, the generation of squeak noise may increase the periphery of the heat exchanger 3, but as described above, On the surface, a protrusion 2b having a height H = 1 mm to 5 mm and having a contact width L2 with the outer member 1 equal to or less than ½ of the width L3 on the heat exchanger 3 side is formed integrally with the heat insulating member 2. And since this protrusion 2a and the outer shell member 1 contact, squeak noise is reduced.

本実施の形態２によれば、特に温度変化による膨張、収縮が大きい熱交換器３の真上において断熱部材２と外郭部材１の接触面積が小さくなっているので、空気調和機の運転開始により急激に温度変化が生じても、きしみ音の発生を効果的に低減することができる。また、突部２ｂが一体成形によって形成されるので、きしみ音の低減には追加材料が不要で、低コストで行うことが可能となる。   According to the second embodiment, since the contact area between the heat insulating member 2 and the outer member 1 is small immediately above the heat exchanger 3 that is particularly large in expansion and contraction due to temperature changes, the operation of the air conditioner is started. Even if the temperature changes suddenly, the generation of squeaking noise can be effectively reduced. Moreover, since the protrusion 2b is formed by integral molding, no additional material is required to reduce squeak noise, and it can be performed at low cost.

実施の形態３．
図７は本発明の実施の形態３にかかる天井埋込形空気調和機の縦断面図、図８は図７の外郭板金の天板を取り外した状態の上面図、図９は図７の断熱部材と外郭部材の接触部近傍を拡大した縦断面図である。実施の形態２では、熱交換器３上部の断熱部材２の表面に突部２ｂを一体成形して点在させたが、本実施の形態３では、温度変化が大きい熱交換器直上での外郭部材１と断熱部材２との接触を回避するための手段を設けたものである。なお、実施の形態１と同一または相当部分には同一符号を付し、詳細な説明は省略する。 Embodiment 3 FIG.
7 is a longitudinal sectional view of a ceiling-embedded air conditioner according to Embodiment 3 of the present invention, FIG. 8 is a top view of the outer sheet metal top plate of FIG. 7 removed, and FIG. 9 is the heat insulation of FIG. It is the longitudinal cross-sectional view which expanded the contact part vicinity of a member and an outer shell member. In the second embodiment, the protrusions 2b are integrally formed on the surface of the heat insulating member 2 above the heat exchanger 3 and are scattered. However, in the third embodiment, the outline just above the heat exchanger having a large temperature change. Means for avoiding contact between the member 1 and the heat insulating member 2 are provided. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and detailed description is abbreviate | omitted.

断熱部材２の表面には、熱交換器３の周囲両側に、熱交換器３に沿った形で断面台形状で壁状に連続する一対の突部２ｃが一体成形され、この突部２ｃは高さがＨ＝１ｍｍ〜５ｍｍであって、外郭部材１と接触するようになっている。
なお、突部２ａは断面ほぼ台形状で壁状に連続する場合を示したが、この形状に限定するものではない。 On the surface of the heat insulating member 2, a pair of protrusions 2 c that are continuous in a wall shape with a trapezoidal cross section along the heat exchanger 3 are integrally formed on both sides around the heat exchanger 3. The height is H = 1 mm to 5 mm so as to come into contact with the outer shell member 1.
In addition, although the protrusion 2a showed the case where a cross section is substantially trapezoid shape and continued in the shape of a wall, it is not limited to this shape.

次に動作について説明する。
実施の形態１と同様に、断熱部材２は熱交換器３を通過した空気により温度変化を受けるが、特に熱交換器３と接触している付近はその他の部分に比べて、温度変化が大きくなる。このため、断熱部材２と外郭部材１が一様に接触している場合には、きしみ音の発生は熱交換器３の周辺が大きくなるおそれがあるが、上述したように、断熱部材２の表面には、高さＨ＝１ｍｍ〜５ｍｍの壁状に連なる突部２ｃが、熱交換器３の周囲両側に断熱部材２と一体に連続して成形され、この突部２ｃと外郭部材１が接触するようになっているので、きしみ音が低減する。 Next, the operation will be described.
As in the first embodiment, the heat insulating member 2 undergoes a temperature change due to the air that has passed through the heat exchanger 3, but the temperature change is particularly large in the vicinity where the heat insulating member 2 is in contact with the heat exchanger 3 compared to other parts. Become. For this reason, when the heat insulating member 2 and the outer shell member 1 are in uniform contact, the generation of squeak noise may increase the periphery of the heat exchanger 3, but as described above, On the surface, protrusions 2c that are continuous in a wall shape with a height H = 1 mm to 5 mm are continuously formed integrally with the heat insulating member 2 on both sides around the heat exchanger 3, and the protrusions 2c and the outer member 1 are formed. Since it comes in contact, squeak noise is reduced.

本実施の形態３によれば、特に温度変化が大きい熱交換器３の直上では断熱部材２と外郭部材１は接触しないので、きしみ音を低減することができる。また、突部２ｃが一体成形によって形成されるので、きしみ音の低減には追加材料が不要で、低コストで行うことが可能となる。   According to the third embodiment, the heat insulating member 2 and the outer member 1 do not contact directly above the heat exchanger 3 where the temperature change is particularly large, so that squeak noise can be reduced. Moreover, since the protrusion 2c is formed by integral molding, no additional material is required to reduce squeak noise, and it can be performed at low cost.
