Description
明 細 書 天井埋込型空気調和装置 技術分野 Description In-ceiling type air conditioner Technical field
本発明は、 天井埋込型空気調和装置の空気吹出口の配置構造に関し、 特に、 冷房 運転時等の空調空気の吹出し方向を調節して、 この空調空気中に含まれる微粒子状の 塵埃が天井面に付着することを防止する汚れ防止技術の分野に属する。 背景技術 The present invention relates to an arrangement structure of an air outlet of a ceiling-embedded air conditioner, and in particular, adjusts a blowing direction of conditioned air during a cooling operation or the like so that particulate dust contained in the conditioned air is removed from the ceiling. It belongs to the field of antifouling technology for preventing adhesion to surfaces. Background art
従来より、 天井埋込型の空気調和装置の吹出口には、 空調空気の吹出し方向を上 下に変更可能な水平羽根が設けられている。 そして、 この水平羽根により空調空気の 吹出し方向を暖房運転時には相対的に下向きにする一方、 冷房運転時には天井面に対 し平行に近くなるよう相対的に上向きにすることで (いわゆる水平吹出し)、 各運転 状態において室内の温度分布の均一化を図り、 空調効率を高めるようにしている。 2. Description of the Related Art Conventionally, horizontal blades capable of changing the blowing direction of conditioned air upward and downward have been provided at the outlet of an air conditioner of a recessed ceiling type. The airflow direction of the conditioned air is directed downward during the heating operation by the horizontal blades, while the airflow direction is directed upward so as to be nearly parallel to the ceiling surface during the cooling operation (so-called horizontal blowing). In each operation state, the temperature distribution in the room is made uniform to improve the air conditioning efficiency.
ところが、 前記の水平吹出し状態では、 吹出される空調空気中に含まれる微粒子 状の塵埃が天井面に付着して、 該天井面が部分的に汚れてしまうことがある。 詳しく は、 図 9に示すように空気調和装置を水平方向から見たとき、 水平吹出し状態で吹出 口(a)から吹出された気流は、 その流れに沿って見て略 V字状になり、 吹出口(a)の長 手方向中央部分では空気の吹出し初速度が高いため、 気流が天井面(b )から離れた領 域を流れるようになる。 また、 この吹出し空気中に含まれる微粒子状の塵埃は慣性力 が高いので、 この塵埃が天井面 (b )に付着することは殆どない。 However, in the horizontal blowing state, fine particulate dust contained in the air-conditioned air that is blown may adhere to the ceiling surface, and the ceiling surface may be partially contaminated. Specifically, as shown in Fig. 9, when the air conditioner is viewed from the horizontal direction, the airflow blown out from the outlet (a) in the horizontal blowout state becomes substantially V-shaped when viewed along the flow, Since the initial velocity of air blowing is high in the central part in the longitudinal direction of the outlet (a), the airflow flows in a region away from the ceiling surface (b). Further, since the particulate dust contained in the blown air has a high inertial force, the dust hardly adheres to the ceiling surface (b).
一方、 吹出口(a)の長手方向両側部分では気流が側方へ拡がったり、 渦になった りして、 前記中央部分に比べて吹出し初速度が低くなるため、 コアンダ効果によって 気流が天井面 (b )に沿って流れるようになる。 しかも、 この吹出し空気中に含まれる 塵埃は慣性力が低く、 天井面 (b )に付着し易いので、 天井面 (b )のうち吹出口(a)の両 側部に近接した領域 (D ) (図 2参照) には空気中の塵埃が付着して、 汚れ易くなる。
このような汚れを回避するために、 特開平 3— 1 6 0 2 6 6号公報には、 水平羽 根に、 吹出し方向を天井面側に移行させる補助フィ ンを着脱自在に設け、 この補助フ インを天井汚れの発生し易さに応じて着脱することが提案されている。 すなわち、 例 えば、 室内空気に塵埃が多くて天井汚れの発生し易い環境や、 或いは病院のように特 に汚れ防止の要求が高い場所では補助フィンを外して、 水平羽根を下向きにする一方、 天井汚れが発生し難い環境や汚れ防止の要求の低い場所では補助フィンを取付けて、 水平吹出しを行えるようにするのである。 一解決課題一 On the other hand, the airflow spreads laterally or becomes vortex at both sides in the longitudinal direction of the air outlet (a), and the initial velocity of the airflow is lower than that of the central part. It flows along (b). Moreover, the dust contained in the blown air has a low inertia force and easily adheres to the ceiling surface (b), so that the area (D) of the ceiling surface (b) which is close to both sides of the air outlet (a). (See Fig. 2), dust in the air adheres to it, making it easier to get dirty. In order to avoid such contamination, Japanese Patent Application Laid-Open No. HEI 3-1602666 discloses that a horizontal blade is provided with a detachable auxiliary fin for shifting a blowing direction to a ceiling surface side. It has been proposed to attach and detach the fins depending on the degree of ceiling dirt. That is, for example, in an environment where indoor air is very dusty and ceiling dirt is likely to occur, or in places such as hospitals where there is a particularly high need for dirt prevention, remove the auxiliary fins and turn the horizontal blades downward, In environments where ceiling dirt is unlikely to occur or where there is little need for dirt prevention, auxiliary fins are installed to enable horizontal blowing. Solution 1
しかし、 前記従来例のような補助フィンを設けたとしても、 この補助フィンは天 井汚れの発生し易い環境等では外さざるを得ず、 結局、 このときには吹出口から空調 空気が常に下向きに吹出されることになるので、 本来、 水平吹出しを行うべき冷房運 転時において空調効率の低下を招くばかりでなく、 冷風が室内の人に直接吹付けられ ることによる違和感 (いわゆるドラフ ト感)の問題も生じる。 However, even if the auxiliary fins are provided as in the conventional example, the auxiliary fins must be removed in an environment where ceiling dirt is likely to be generated, and eventually, at this time, the conditioned air always blows downward from the air outlet. Because of this, not only does air-conditioning efficiency decrease during cooling operation, which should normally perform horizontal blowing, but also the sense of discomfort (so-called “draft feeling”) due to the direct blow of cold air to people indoors. Problems arise.
本発明は、 斯かる点に鑑みてなされたものであり、 その目的とするところは、 空 調空気の吹出口の配置構成等に工夫を凝らすことで、 空調装置の運転状態に応じた適 切な吹出し方向を得ながら、 天井面の汚れを防止することにある。 発明の開示 The present invention has been made in view of such a point, and an object of the present invention is to devise the arrangement of air-conditioning air outlets and the like so that an appropriate air conditioner operating condition can be attained. The purpose is to prevent dirt on the ceiling surface while obtaining the blowing direction. Disclosure of the invention
本発明は、 前記の課題を解決するために次の手段を講じている。 The present invention employs the following means to solve the above problems.
第 1の発明は、 天井面(70 )に埋め込まれ、 室内空間に向かって空調空気を吹出す 吹出口(16 )が設けられているとともに、 該吹出口(16 )に空調空気の吹出し方向を案内 可能な案内手段(18)が設けられた天井埋込型空気調和装置を前提とし、 このものにお いて、 前記案内手段(18 )により吹出し方向が案内される側の吹出口形成部材の最下部 を、 天井面 ( 70 )から下方に 4 5 mm以上離れるように配置した。 尚、 前記案内手段(1 8 )としては、 例えば吹出口(16 )に至る上流側の空気通路を湾曲させて、 吹き出される 空調空気の方向を案内するようにすればよい。 また、 前記吹出口形成部材の最下部は、
天井面(70)から 45mm離れていることが好ましい (第 2の発明) 。 According to a first aspect of the present invention, an air outlet (16) which is embedded in a ceiling surface (70) and blows out conditioned air toward an indoor space is provided, and the air outlet direction of the conditioned air is supplied to the air outlet (16). Assuming that the ceiling-embedded type air conditioner is provided with a guide means (18) capable of guiding, in this case, the air outlet forming member on the side where the blowing direction is guided by the guide means (18) is described. The lower part was placed at least 45 mm below the ceiling surface (70). As the guide means (18), for example, the air passage on the upstream side to the outlet (16) may be curved to guide the direction of the conditioned air to be blown. Also, the lowermost part of the outlet forming member, Preferably, it is 45 mm away from the ceiling surface (70) (second invention).
この発明によれば、 冷房運転時等に空気調和装置(1)の吹出口(16)から吹出され る空調空気は案内手段(18)により案内されて室内空間に吹出す噴流となり、 その噴流 軸はコアンダ効果によって天井面(70)の方向に曲げられる。 しかしながら、 前記案内 手段(18)により吹出し方向が案内される側の吹出口形成部材の最下部が、 天井面 (70) から下方に 45mm以上離れているので、 一般的な吹出し速度の空気であれば、 相対 的に吹出し初速度の低い吹出口(16)の長手方向両側部分の流れであっても、 その空気 の流れは天井面(70)にまで届くことはなく、 やがて室内空気との温度差によって下降 するようになる。 According to the present invention, the air-conditioned air blown out from the air outlet (16) of the air conditioner (1) during a cooling operation or the like is guided by the guide means (18) to become a jet blown into the indoor space. Is bent in the direction of the ceiling surface (70) by the Coanda effect. However, since the lowermost part of the outlet forming member on the side where the blowing direction is guided by the guide means (18) is separated from the ceiling surface (70) by 45 mm or more, even if the air has a general blowing speed, For example, even if the air flows at both sides in the longitudinal direction of the outlet (16), which has a relatively low initial velocity, the air flow does not reach the ceiling surface (70), and eventually the temperature of the air with the room air rises. It starts to fall by the difference.
このことで、 空調空気の吹出し方向を天井面に対し平行に近くなるように上向き にしても、 空気流が天井面に沿って流れることはなくなり、 よって、 いわゆる水平吹 出し状態における天井面の汚れを防止することができる。 第 3の発明では、 前記第 1の発明において、 空気調和装置本体(10)は、 天井面に 対し固定され、 室内空間に臨むように吹出口(16)が設けられたパネル部材(14)を有し ていて、 このパネル部材(14)と天井面(70)との間の上下方向の間隔を調節するスぺー サ部材(72)を設けるものとする。 This prevents the airflow from flowing along the ceiling surface even when the air-conditioning air blowing direction is set to be nearly parallel to the ceiling surface. Can be prevented. In a third aspect based on the first aspect, the air conditioner main body (10) includes a panel member (14) fixed to a ceiling surface and provided with an air outlet (16) so as to face an indoor space. And a spacer member (72) for adjusting the vertical distance between the panel member (14) and the ceiling surface (70).
この発明によれば、 天井の汚れ防止の要求が高い状況ではスぺーサ部材(72)によ つてパネル部材(14)と天井面 (70)との間の間隔を調節して、 吹出口(16)と天井面 (70) との間隔を調節することにより、 空調空気の吹出し方向が案内される側の吹出口形成 部材の最下部を、 確実に天井面(70)から下方に 45mm以上離れるように設定できる。 一方、 汚れ防止の要求が低ければ、 同じ空気調和装置(1)をスぺ一サ部材(72)なしで 設置することも可能であり、 こうすれば、 空気調和装置(1)と天井面(70)との一体感 を高めて、 見栄えを向上できる。 第 4の発明では、 前記第 1の発明において、 案内手段(18)により吹出し方向が案 内される側の吹出口形成部材に、 吹出口(16)の端縁部から空気調和装置本体(10)の外
周側に向かって、 天井面に近づくように傾斜する外部傾斜面(14a)を形成し、 この外 部傾斜面(14a)の少なくとも前記吹出口(16)端縁部付近における天井面に対する傾斜 角度を、 10度以上とした。 尚、 該傾斜角度は 10. 8度とすることが好ましい (第 8の発明) 。 According to the present invention, in a situation where there is a high demand for the prevention of dirt on the ceiling, the distance between the panel member (14) and the ceiling surface (70) is adjusted by the spacer member (72) so that the air outlet ( By adjusting the distance between 16) and the ceiling surface (70), the lowermost part of the air outlet forming member on the side where the direction of air-conditioning air is guided is securely separated from the ceiling surface (70) by 45mm or more. It can be set as follows. On the other hand, if the requirement for dirt prevention is low, it is possible to install the same air conditioner (1) without a spacer member (72). In this case, the air conditioner (1) and the ceiling ( 70) to enhance the sense of unity and improve the appearance. In a fourth aspect of the present invention, in the first aspect, the air conditioning apparatus main body (10) is provided from the end of the air outlet (16) to the air outlet forming member on the side where the blowing direction is envisaged by the guide means (18). Outside of) An outer inclined surface (14a) is formed so as to be inclined toward the peripheral surface so as to approach the ceiling surface, and an inclination angle of the outer inclined surface (14a) with respect to the ceiling surface at least near the edge of the outlet (16). Was set to 10 degrees or more. The inclination angle is preferably set to 10.8 degrees (eighth invention).
この発明によれば、 吹出口(16)から吹き出される空調空気の流れと吹出口形成部 材の外部傾斜面(14a)との間のコアンダ効果を弱めて、 前記第 1の発明の作用効果を 高めることができる。 第 5の発明では、 前記第 1の発明において、 空気調和装置本体(10)及び天井面 (7 0)の境界位置と案内手段(18)により吹出し方向が案内される側の吹出口形成部材の最 下部とを結ぶ線の天井面 (70)に対する傾斜角度を、 1 0度以上とした。 尚、 該傾斜角 度は 10. 8度とすることが好ましい (第 1 0の発明) 。 According to the present invention, the Coanda effect between the flow of the conditioned air blown out from the outlet (16) and the outer inclined surface (14a) of the outlet forming member is reduced, and the operation and effect of the first aspect of the present invention are reduced. Can be increased. In a fifth aspect of the present invention, in the first aspect, the outlet port forming member on the side where the blowing direction is guided by the boundary position between the air conditioner body (10) and the ceiling surface (70) and the guide means (18). The inclination angle of the line connecting the bottom with the ceiling surface (70) was set to 10 degrees or more. The inclination angle is preferably set to 10.8 degrees (the tenth invention).
この発明によれば、 吹出口(16)から吹き出される空調空気の流れと吹出口形成部 材の表面との間のコアンダ効果を弱めて、 前記第 3の発明と同様の作用効果を得るこ とができる。 第 6の発明では、 前記第 1の発明において、 案内手段(18)により吹出し方向が案 内される側の吹出口形成部材の最下部から空気調和装置本体(10)の外周側に向かって 天井面に近づくように傾斜する第 1傾斜面( 14a)と、 この第 1傾斜面( 14a)に続く第 2 傾斜面とを形成するとともに、 前記第 1傾斜面(14a)の天井面(70)に対する傾斜角度 を 1 2度以下とし、 また、 前記第 2傾斜面の天井面 (70)に対する傾斜角度は 1 2度を 超えるものとした。 According to this invention, the Coanda effect between the flow of the conditioned air blown out from the air outlet (16) and the surface of the air outlet forming member is weakened, and the same effect as the third invention can be obtained. Can be. In a sixth aspect based on the first aspect, the ceiling extends from the lowermost portion of the air outlet forming member on the side where the blowing direction is envisaged by the guide means (18) toward the outer peripheral side of the air conditioner body (10). A first inclined surface (14a) inclined to approach the surface, a second inclined surface following the first inclined surface (14a), and a ceiling surface (70) of the first inclined surface (14a). And the inclination angle of the second inclined surface with respect to the ceiling surface (70) is greater than 12 degrees.
この発明によれば、 吹出口(16)から吹き出される空調空気の一部は、 第 1傾斜面 (14a)に沿って流れて、 該第 1傾斜面(14a)と第 2傾斜面との境界位置で剥離するよう になり、 これにより、 前記第 1の発明の作用効果を高めることができる。 第 7の発明は、 天井面(70)に埋め込まれ、 室内空間に向かって空調空気を吹出す
吹出口(16)が設けられているとともに、 該吹出口(16)に空調空気の吹出し方向を案内 可能な案内手段(18)が設けられた天井埋込型空気調和装置を前提とする。 そして、 前 記案内手段(18)により吹出し方向が案内される側の吹出口形成部材に、 吹出口(16)の 端縁部から空気調和装置本体(10)の外周側に向かって、 天井面に近づくように傾斜す る外部傾斜面(14a)を形成し、 この外部傾斜面(14a)の少なくとも前記吹出口(16)端縁 部付近における天井面に対する傾斜角度を、 1 0度以上とした。 尚、 該傾斜角度は 1 0. 8度とすることが好ましい (第 8の発明) 。 According to the present invention, part of the conditioned air blown out from the outlet (16) flows along the first inclined surface (14a), and the air-conditioning air flows between the first inclined surface (14a) and the second inclined surface. It comes off at the boundary position, whereby the operation and effect of the first invention can be enhanced. The seventh invention is embedded in the ceiling surface (70) and blows out conditioned air toward the indoor space. It is assumed that the air conditioner is a ceiling-embedded type air conditioner provided with an air outlet (16) and a guide means (18) capable of guiding the direction of air-conditioned air to the air outlet (16). The outlet forming member on the side where the blowing direction is guided by the guide means (18) has a ceiling surface extending from the edge of the outlet (16) toward the outer peripheral side of the air conditioner body (10). An external inclined surface (14a) is formed so as to be inclined so as to approach the ceiling, and the inclination angle of the external inclined surface (14a) with respect to the ceiling surface at least near the edge of the outlet (16) is set to 10 degrees or more. . The inclination angle is preferably set to 10.8 degrees (eighth invention).
この発明によれば、 冷房運転時等に空気調和装置(1)の吹出口(16)から吹出され る空調空気は案内手段(18)により案内されて室内空間に吹出す噴流となり、 その噴流 軸はまず吹出口形成部材の外部傾斜面(14a)との間のコアンダ効果によって上向きに 曲げられる。 しかし、 前記外部傾斜面(14a)の少なくとも吹出口(16)端縁部付近にお ける傾斜角度が天井面(70)に対し 10度以上と大きいことから、 コアンダ効果は緩和 され、 空気流は天井面(70)に届き難くなる。 これにより、 空調空気の吹出し方向を上 向きにしても、 その吹出し空気流が天井面(70)に沿って流れることを抑制でき、 よつ て、 いわゆる水平吹出し状態における天井面の汚れを大幅に軽減できる。 第 9の発明は、 天井面(70)に埋め込まれ、 室内空間に向かって空調空気を吹出す 吹出口(16)が設けられているとともに、 該吹出口(16)に空調空気の吹出し方向を案内 可能な案内手段(18)が設けられた天井埋込型空気調和装置を前提とする。 そして、 空 気調和装置本体 (10)及び天井面 (70)の境界位置と案内手段(18)により吹出し方向が案 内される側の吹出口形成部材の最下部とを結ぶ線の天井面 (70)に対する傾斜角度を、 10度以上とした。 尚、 該傾斜角度は 1 0. 8度とすることが好ましい (第 1 0の発 明) 。 According to the present invention, the air-conditioned air blown out from the air outlet (16) of the air conditioner (1) during a cooling operation or the like is guided by the guide means (18) to become a jet blown into the indoor space. Is first bent upward by the Coanda effect between the outer slope surface (14a) of the outlet forming member. However, since the angle of inclination of the outer inclined surface (14a) at least near the edge of the outlet (16) is as large as 10 degrees or more with respect to the ceiling surface (70), the Coanda effect is reduced, and the airflow is reduced. It becomes difficult to reach the ceiling surface (70). As a result, even when the air-conditioning air blowing direction is directed upward, the blowing air flow can be suppressed from flowing along the ceiling surface (70), and thus, the dirt on the ceiling surface in a so-called horizontal blowing state can be significantly reduced. Can be reduced. According to a ninth aspect of the present invention, an air outlet (16) is provided which is embedded in a ceiling surface (70) and blows conditioned air toward an indoor space, It is assumed that the ceiling-mounted air conditioner is provided with a guiding means (18) capable of guiding. Then, the ceiling surface of the line connecting the boundary position between the air conditioner body (10) and the ceiling surface (70) and the lowermost part of the outlet forming member on the side where the blowing direction is envisaged by the guide means (18) ( The inclination angle with respect to 70) was set to 10 degrees or more. Note that the inclination angle is preferably set to 10.8 degrees (the tenth invention).
この発明によれば、 吹出口(16)から吹き出される空調空気の流れと吹出口形成部 材の下面との間のコアンダ効果を弱めて、 前記第 7の発明と同様の作用効果を得るこ とができる。
第 1 1の発明は、 天井面(70)に埋め込まれ、 室内空間に向かって空調空気を吹出 す吹出口(16)が設けられているとともに、 該吹出口(16)に空調空気の吹出し方向を案 内可能な案内手段(18)が設けられた天井埋込型空気調和装置を前提とする。 そして、 前記案内手段(18)により吹出し方向が案内される側の吹出口形成部材の最下部から空 気調和装置本体(10)の外周側に向かって天井面に近づくように傾斜する第 1傾斜面(1 4a)と、 この第 1傾斜面(14a)に続く第 2傾斜面とを形成するとともに、 前記第 1傾斜 面(14a)の天井面(70)に対する傾斜角度を 1 2度以下とし、 また、 前記第 2傾斜面の 天井面 (70)に対する傾斜角度は 12度を超えるものとした。 According to this invention, the Coanda effect between the flow of the conditioned air blown out from the air outlet (16) and the lower surface of the air outlet forming member is reduced, and the same operation and effect as the seventh invention can be obtained. Can be. According to the eleventh invention, an air outlet (16) is provided which is embedded in a ceiling surface (70) and blows out conditioned air toward an indoor space, and a direction in which the conditioned air is blown into the air outlet (16). It is assumed that the ceiling-mounted air conditioner is provided with a guide means (18) that can be provided.

Surface (14a) and a second inclined surface following the first inclined surface (14a), and the inclination angle of the first inclined surface (14a) with respect to the ceiling surface (70) is set to 12 degrees or less. In addition, the inclination angle of the second inclined surface with respect to the ceiling surface (70) is more than 12 degrees.
この発明によれば、 冷房運転時等に空気調和装置(1)の吹出口(16)から吹出され る空調空気は案内手段(18)により案内されて室内空間に吹出す噴流となり、 その空気 流の一部は第 1傾斜面(14a)に沿って流れて、 該第 1傾斜面(14a)と第 2傾斜面との境 界位置で剥離するようになる。 これにより、 空気流は殆ど天井面(70)に届くことはな く、 よって、 いわゆる水平吹出し状態における天井面の汚れを大幅に軽減できる。 第 1 2の発明では、 前記第 6又は第 1 1のいずれかの発明において、 吹出口形成 部材の最下部から第 1傾斜面(Ha)及び第 2傾斜面の境界位置までの距離を、 70m m以上とした。 According to the present invention, the conditioned air blown out from the air outlet (16) of the air conditioner (1) during a cooling operation or the like is guided by the guide means (18) to become a jet blown into the indoor space. A part of the air flows along the first inclined surface (14a) and separates at a boundary position between the first inclined surface (14a) and the second inclined surface. As a result, the airflow hardly reaches the ceiling surface (70), so that the dirt on the ceiling surface in a so-called horizontal blowing state can be greatly reduced. In a twelfth invention, in any one of the sixth and eleventh inventions, the distance from the lowermost part of the outlet forming member to the boundary position between the first inclined surface (Ha) and the second inclined surface is 70 m. m or more.
この発明によれば、 前記第 6又は第 1 1の発明の作用効果を十分に得ることがで きる。 第 1 3の発明では、 前記第 4、 5、 6、 7、 9又は 1 1のいずれか 1つの発明に おいて、 案内手段(18)により吹出し方向が案内される側の吹出口形成部材の最下部を、 空気調和装置本体(10)と天井面 (70)との境界位置から水平方向に 75mm以上離れる ように配置した。 尚、 前記吹出口形成部材の最下部は、 空気調和装置本体(10)と天井 面 (70)との境界位置から水平方向に 79mm離すことが好ましい (第 14の発明) 。 According to the present invention, the function and effect of the sixth or eleventh invention can be sufficiently obtained. According to a thirteenth invention, in any one of the fourth, fifth, sixth, seventh, ninth and eleventh inventions, the air outlet forming member on the side where the blowing direction is guided by the guiding means (18) is provided. The lowermost part was placed so as to be at least 75 mm horizontally apart from the boundary between the air conditioner body (10) and the ceiling surface (70). It is preferable that the lowermost part of the outlet forming member is horizontally 79 mm apart from a boundary position between the air conditioner main body (10) and the ceiling surface (70) (a fourteenth invention).
この発明によれば、 吹出口( 16 )から吹き出された空調空気の一部はコアンダ効果 によって上向きに曲げられて、 吹出口形成部材に沿って流れるようになるが、 該吹出
口形成部材の最下部が天井面(70 )との境界位置から水平方向に十分に離れているので、 前記のように吹出口形成部材に沿って流れる空気流の大部分は天井面(70 )にまで達す る前に下降するようになり、 このことによつても天井面(70 )の汚れを大幅に軽減でき る。 第 1 5の発明は、 天井面(70 )に埋め込まれ、 室内空間に向かって空調空気を吹出 す吹出口(16 )が設けられているとともに、 該吹出口(16 )に空調空気の吹出し方向を案 内可能な案内手段(18 )が設けられた天井埋込型空気調和装置を前提とし、 このものに おいて、 前記案内手段(18 )により吹出し方向が案内される側の吹出口形成部材の最下 部を、 空気調和装置本体 ( 10 )と天井面(70 )との境界位置から水平方向に 7 5 mm以上 離れるように配置した。 尚、 前記吹出口形成部材の最下部は、 空気調和装置本体(10) と天井面(70 )との境界位置から水平方向に 7 9 mm離すことが好ましい (第 1 6の発 明) 。 According to the present invention, a part of the conditioned air blown out from the outlet (16) is bent upward by the Coanda effect and flows along the outlet forming member. Since the lowermost part of the mouth forming member is sufficiently separated in the horizontal direction from the boundary position with the ceiling surface (70), most of the airflow flowing along the outlet forming member as described above is large. , Before descending, which can greatly reduce the dirt on the ceiling surface (70). According to a fifteenth aspect of the present invention, an air outlet (16) which is embedded in a ceiling surface (70) and blows out conditioned air toward an indoor space is provided, and It is assumed that the ceiling-mounted air conditioner is provided with a guide means (18) that can be provided. In this apparatus, the outlet forming member on the side where the blowing direction is guided by the guide means (18) is provided. The lowermost part of the air conditioner was placed horizontally at least 75 mm away from the boundary between the air conditioner body (10) and the ceiling surface (70). It is preferable that the lowermost part of the outlet forming member is horizontally separated from the boundary between the air conditioner main body (10) and the ceiling surface (70) by 79 mm in the horizontal direction (the sixteenth invention).
この発明によれば、 冷房運転時等に空気調和装置(1 )の吹出口(16 )から吹出され る空調空気は案内手段(18 )により案内されて室内空間に吹出す噴流となり、 その噴流 軸はまず吹出口形成部材との間のコアンダ効果によって上向きに曲げられて、 その空 気流の一部が吹出口形成部材に沿って流れるようになる。 しかし、 該吹出口形成部材 の最下部が天井面(70 )との境界位置から水平方向に 7 5 mm以上と十分に離れている ことから、 前記のように吹出口形成部材に沿って流れる空気流が天井面 (70 )にまで達 することは少なく、 この空気流はやがて室内空気との温度差によって下降するように なる。 従って、 吹出し空気流が天井面(70 )に沿って流れることを抑制して、 いわゆる 水平吹出し状態における天井面の汚れを大幅に軽減できる。 According to the present invention, the air-conditioning air blown out from the air outlet (16) of the air conditioner (1) during a cooling operation or the like is guided by the guide means (18) to become a jet to be blown into the indoor space. Is bent upward by the Coanda effect between the air outlet forming member and a part of the airflow flows along the air outlet forming member. However, since the lowermost part of the outlet forming member is sufficiently separated from the boundary position with the ceiling surface (70) in the horizontal direction by 75 mm or more, the air flowing along the outlet forming member as described above. The flow rarely reaches the ceiling surface (70), and this air flow eventually falls due to the temperature difference with the room air. Therefore, the blown air flow is prevented from flowing along the ceiling surface (70), and the dirt on the ceiling surface in a so-called horizontal blowing state can be greatly reduced.
尚、 前記のように吹出口( 16 )からの吹出し空気流の一部が吹出口形成部材に沿つ て流れる結果、 その空気流に含まれる塵埃が吹出口形成部材に付着して、 この吹出口 形成部材を汚すことが考えられるが、 この点については、 例えば、 吹出口形成部材の 表面を汚れの付き難い状態に加工したり、 或いは吹出口形成部材の表面を付着した汚 れの取れ易い状態に加工したりすることで、 効果的に対応できる。
第 1 7の発明では、 前記第 1、 7、 9、 1 1又は 1 5のいずれか 1つの発明にお ける吹出口(16)に、 空調空気の吹出口(16 )の長手方向への流れを規制する整流部材(1 9)を配設した。 As described above, a part of the airflow blown out from the outlet (16) flows along the outlet forming member, so that dust contained in the airflow adheres to the outlet forming member, and It is conceivable that the outlet forming member is contaminated, but in this regard, for example, the surface of the outlet forming member is processed so as to be hardly soiled, or the surface of the outlet forming member is easily removed from the surface. It can respond effectively by processing it into a state. In the seventeenth invention, the air outlet (16) according to any one of the first, seventh, ninth, eleventh and fifteenth inventions has a structure in which the flow of air-conditioned air in the longitudinal direction of the air outlet (16) is provided. A rectifying member (19) that regulates the air pressure is provided.
この発明によれば、 吹出口(16 )から吹出される空調空気は、 該吹出口(16 )の長手 方向への流れが整流部材(19)により規制されて、 吹出し方向へ向かうように整流され るので、 その吹出し初速度は吹出口(16 )の両側部分でも中央部分と同様に高くなり、 このことによって、 水平吹出し状態で空調空気が上向きに流れることをさらに効果的 に抑制できる。 尚、 前記整流部材(19)は、 吹出口(16)の少なくとも長手方向略両端部 に配置するようにすればよい。 第 1 8の発明では、 前記第 1、 7、 9、 1 1又は 1 5のいずれか 1つの発明にお ける案内手段(18)を、 空調空気の吹出し方向を上下に変更可能な水平羽根とする。 According to the present invention, the conditioned air blown out from the outlet (16) is rectified so that the flow in the longitudinal direction of the outlet (16) is regulated by the rectifying member (19) and heads in the blowing direction. Therefore, the initial velocity of the blow-out increases at both sides of the blow-out opening (16) as well as at the central portion, whereby the upward flow of the conditioned air in the horizontal blow-out state can be more effectively suppressed. The rectifying member (19) may be arranged at least at substantially both ends in the longitudinal direction of the outlet (16). In the eighteenth invention, the guide means (18) in any one of the first, seventh, ninth, eleventh and fifteenth inventions is provided with a horizontal blade capable of changing a blowing direction of conditioned air up and down. I do.
この発明によれば、 吹出口(16 )からの空調空気の流れを水平羽根(18)により上下 に変更することができるので、 この吹出し空気の流れを暖房運転時には相対的に下向 きにする一方、 冷房運転時には水平吹出し状態として、 各運転状態で空調効率を高め ることができる。 特に冷房運転時には、 吹出し空気の流れが天井面(70 )に沿って流れ ることのない範囲で、 この空気流を水平羽根(18)によりできるだけ水平に近づけるよ うにすれば、 前記の作用効果を十分に得ることができる。 第 1 9の発明では、 前記第 1 8の発明における水平羽根(18)に、 空調空気の吹出 口(16)の長手方向への流れを規制する整流板(19)を配設した。 According to the present invention, the flow of the conditioned air from the outlet (16) can be changed up and down by the horizontal blades (18), so that the flow of the blown air is relatively downward during the heating operation. On the other hand, during the cooling operation, the air is efficiently discharged in each operation state by setting the air to the horizontal blowing state. In particular, during the cooling operation, if the air flow is made as horizontal as possible by the horizontal blades (18) within a range in which the flow of the blown air does not flow along the ceiling surface (70), the above-mentioned effect is obtained. Can get enough. In the nineteenth invention, a rectifying plate (19) for restricting the flow of the conditioned air in the longitudinal direction of the air outlet (16) is provided on the horizontal blade (18) in the eighteenth invention.
この発明によれば、 水平羽根(18)上の整流板(19)により吹出し空気の流れが効果 的に整えられ、 空気流の吹出し初速度は吹出口(16 )の両側部分でも中央部分と同様に 高くなるので、 水平吹出し状態で空調空気が上向きに流れることをさらに効果的に抑 制できる。 尚、 前記整流部材(19)は、 水平羽根(18)上における吹出口(16 )の少なくと も長手方向略両端部に対応するように配置すればよい。
第 2 0の発明では、 前記第 1 9の発明における水平羽根(18)を、 幅方向に亘つて 湾曲する長尺状の板部材からなるものとし、 整流板(19)は、 前記水平羽根(18)の内側 に湾曲する面上に長手方向の全体に亘つて所定間隔を空けて配置した。 According to the present invention, the flow of the blown air is effectively regulated by the flow straightening plate (19) on the horizontal blade (18), and the initial speed of the blown air flow is the same at both sides of the outlet (16) as in the central portion. Therefore, it is possible to more effectively suppress the upward flow of the conditioned air in the horizontal blowing state. The rectifying member (19) may be arranged so as to correspond to at least substantially both ends in the longitudinal direction of the outlet (16) on the horizontal blade (18). In the twenty-first invention, the horizontal blade (18) according to the nineteenth invention is formed of an elongated plate member that is curved in the width direction, and the rectifying plate (19) includes the horizontal blade (18). They were arranged at predetermined intervals over the entire surface in the longitudinal direction on the inwardly curved surface of 18).
この第 2 0の発明によれば、 幅方向に湾曲した長尺状の水平羽根(18)により空調 空気の流れを滑らかに変化させて、 吹出し方向を変更させることができる。 また、 そ の湾曲する内側の面上に長手方向の全体に亘つて整流板を配置したことで、 それらの 整流板により吹出し空気の流れを全体的に整流できる。 第 2 1の発明では、 前記第 1、 7、 9、 1 1又は 1 5のいずれか 1つの発明にお いて、 吹出口(16 )中央部付近の空気流の吹出し初速度は、 略 2 m/秒以上であってか つ略 6 m/秒以下とする。 According to the 20th aspect, the flow of the conditioned air can be smoothly changed by the long horizontal blades (18) curved in the width direction to change the blowing direction. In addition, by arranging the flow straightening plates over the entire curved inner surface in the longitudinal direction, the flow of the blown air can be entirely flow-rectified by those flow straightening plates. In the twenty-first aspect, in any one of the first, seventh, nineteenth, eleventh and fifteenth aspects, the initial velocity of the air flow near the center of the outlet (16) is approximately 2 m. / Sec or more and approximately 6 m / sec or less.
この発明によれば、 吹出し騒音の増大を招くことなく、 水平吹出し状態でも空気 流が上向きに流れることを十分に抑制できる。 第 2 2の発明では、 前記第 1、 7、 9、 1 1又は 1 5のいずれか 1つの発明にお いて、 吹出口(16 )に至る空調空気の助走距離は、 3 0 mm以上とする。 According to the present invention, it is possible to sufficiently suppress the airflow from flowing upward even in the horizontal blowing state without increasing the blowing noise. In the second invention, in any one of the first, seventh, ninth, eleventh and fifteenth inventions, the running distance of the conditioned air reaching the air outlet (16) is 30 mm or more. .
この発明によれば、 吹出口(16 )から吹き出さされる空調空気の流れは、 全体的に 吹出し方向へ向かうように整えられるので、 特に吹出口(16 )の両側部分における吹出 し空気の速度を高めて、 水平吹出し状態でもその空気流が上向きになることを抑制す ることができる。 第 2 3の発明では、 前記第 1、 7、 9、 1 1又は 1 5のいずれか 1つの発明にお いて、 吹出口(16 )から吹出す空気流の最終的に空気調和装置本体(10 )から剥離する位 置を、 該空気調和装置本体(10 )及び天井面(70 )の境界位置から 9 O mm以上離れるよ うに設定した。 According to the present invention, the flow of the conditioned air blown out from the outlet (16) is adjusted so as to be generally directed in the blowing direction, so that the speed of the blown air on both sides of the outlet (16) is particularly reduced.

なっている。 そして、 この実施形態 1の主たる特徴部分は、 空気調和装置(1)の化粧パネル(1 4)と天井板(70)との間に両者の上下方向間隔を調節するスぺーサ部材 (72)が介設さ れていて、 このことで、 前記図 3に示すように、 化粧パネル(14)における空気吹出口 (16)の上縁部、 即ち水平羽根(18)により空調空気の吹出し方向が案内される側の吹出 口形成部材の最下部と、 天井板(70)の下面との間の上下方向の間隔 hが 45 mm以上 (好ましくは 45mm) に設定されているとともに、 該空気吹出口(16)の上縁部と化 粧パネル(14)の外周縁部 (化粧パネル(14)及び天井板 (70)の境界位置) との間隔 が 90mm以上に設定されていることにある。 In other words, the air filter (17), bellmouth (27), fan (20), and heat exchanger are located in the body casing (11) of the air conditioner (1) through the air inlet (15) of the decorative panel (14). An air flow passage (W) is formed through the vessel (30) to the air outlet (16). When the fan (20) is driven during the air conditioning operation, the room air taken into the casing (10) from the air suction port (15) via the air filter (17) is supplied to the bell mouth (27) and the fan. (20) and the heat exchanger (30) in this order in the air flow passage (W) to exchange heat with the refrigerant in the heat exchanger (30) to control the temperature (for cooling operation). Is cooled and heated in the heating operation), and then blown out as air-conditioned air from the air outlet (16) into the indoor space so that air conditioning of the indoor space is performed. Has become. The main characteristic part of the first embodiment is that a spacer member (72) for adjusting the vertical space between the decorative panel (14) and the ceiling panel (70) of the air conditioner (1) is provided between the decorative panel (14) and the ceiling panel (70). As a result, as shown in FIG. 3, the upper edge of the air outlet (16) in the decorative panel (14), that is, the horizontal blade (18), allows the air-conditioning air to blow out. A vertical distance h between the lowermost part of the outlet forming member on the guided side and the lower surface of the ceiling plate (70) is set to 45 mm or more (preferably 45 mm), and the air outlet is provided. (16) The distance between the upper edge of the decorative panel (14) and the outer edge of the decorative panel (14) (the boundary position between the decorative panel (14) and the ceiling panel (70)) is set to 90 mm or more.
言い換えると、 この実施形態では、 前記空気吹出口(16)から吹出す空気流の最終 的に化粧パネル(14)から剥離する位置は、 天井板(70)下面から下方に 45mm以上離 れていて、 かつその位置から化粧パネル(14)及び天井板(70)の境界位置までの距離 L が 9 Omm以上になっており、 これにより、 冷房運転時に空気吹出口(16)からいわゆ る水平吹き出し状態で吹き出される空調空気が天井板(70)下面に沿って流れることを 防止できるものである。 すなわち、 まず暖房運転時等のように空調空気を比較的下向 きに吹出させる要求があるときには、 前記図 4に示すように水平羽根(18)を略鉛直下 向きにして、 空調空気を該水平羽根(18)と空気吹出口(16)のパネル外周側の鉛直面 (16a) とに沿わせて、 同図に矢印 Sで示すように略鉛直下向きに吹き出させる。 In other words, in this embodiment, the position where the airflow blown out from the air outlet (16) finally separates from the decorative panel (14) is at least 45 mm below the lower surface of the ceiling plate (70). And the distance L from that position to the boundary between the decorative panel (14) and the ceiling panel (70) is 9 Omm or more, so that during the cooling operation, the so-called horizontal blowing from the air outlet (16) is performed. The conditioned air blown out in the state can be prevented from flowing along the lower surface of the ceiling plate (70). That is, when there is a request to blow the conditioned air relatively downward, such as during a heating operation, the horizontal blades (18) are directed substantially vertically downward as shown in FIG. Along the horizontal vane (18) and the vertical surface (16a) on the outer peripheral side of the panel of the air outlet (16), the air is blown substantially vertically downward as indicated by the arrow S in the figure.
一方、 冷房運転時等にいわゆる水平吹出し状態とするときには、 前記図 3に示す ように、 水平羽根(18)を上向きに回動させて、 該水平羽根(18)の前面(18a)を空気吹 出口(16)のパネル外周側側壁の傾斜面 (16b) と略平行にさせる。 こうすることで、 空調空気は空気吹出口(16)に連通する空気通路 (助走路) の側壁に沿って、 湾曲面(6 c)から水平羽根(18)の前面(18a)に沿うように湾曲して流れ、 その流線の方向が大き くかつ滑らかに変化して、 同図に矢印 Sで示すように、 空気吹出口(16)のパネル外周 側の傾斜面(16b)と水平羽根(18)との間を通って、 空気吹出口(16)から天井板(70)下 面に平行に近い角度 (例えば、 天井板(70)下面となす角度が略 30° 〜35° ) で吹
出される。 On the other hand, when a so-called horizontal blowing state is set during a cooling operation or the like, as shown in FIG. 3, the horizontal blade (18) is turned upward to blow the front surface (18a) of the horizontal blade (18). The exit (16) should be substantially parallel to the inclined surface (16b) of the outer peripheral side wall of the panel. In this way, the conditioned air flows along the side wall of the air passage (runway) communicating with the air outlet (16), along the curved surface (6c) and along the front surface (18a) of the horizontal blade (18). The flow is curved and the direction of the streamline changes greatly and smoothly. As shown by the arrow S in the figure, the inclined surface (16b) on the outer peripheral side of the panel of the air outlet (16) and the horizontal blade ( 18), and blow from the air outlet (16) at an angle almost parallel to the lower surface of the ceiling plate (70) (for example, the angle between the lower surface of the ceiling plate (70) and the lower surface is approximately 30 ° to 35 °). Will be issued.
このとき、 空気吹出口(16)から室内空間に吹出す空調空気は噴流となり、 その吹 出し角度が天井板(70)下面に平行に近いときには、 噴流軸がコアンダ効果によって上 方に曲げられることになるが、 この実施形態では、 前記のように空気吹出口(16)が天 井板 (70)から適度に離れて配置されているため、 該空気吹出口(16)中央部付近の空気 流の吹出し初速度が例えば約 2〜 6 m/秒くらいの一般的な値であれば、 相対的に吹 出し初速度の低い吹出口(16)両側部分の流れも含めて、 その空調空気の流れは天井板 (70)下面まで上昇することはなく、 やがて室内空気との温度差によって下降してゆく。 At this time, the conditioned air blown into the indoor space from the air outlet (16) becomes a jet, and when the blow angle is nearly parallel to the lower surface of the ceiling plate (70), the jet axis is bent upward by the Coanda effect. However, in this embodiment, since the air outlet (16) is appropriately spaced from the ceiling plate (70) as described above, the air flow near the center of the air outlet (16) is reduced. If the initial velocity of the air outlet is a general value of, for example, about 2 to 6 m / s, the flow of the air-conditioned air including the flow on both sides of the outlet (16) with a relatively low initial velocity Does not rise to the lower surface of the ceiling plate (70), but eventually falls due to the temperature difference with room air.
すなわち、 従来から、 天井埋込型の空気調和装置において空気の吹出し速度が低 い部分では、 コアンダ効果によって空気流が天井板(70)下面に接近し易く、 冷房運転 時に水平羽根(18)により空調空気の吹出し方向を相対的に上向けて、 天井板(70)下面 に対し例えば 40〜45° くらいにすると、 空気流が天井板 (70)下面に沿って流れて、 図 2に仮想線で示すような領域 (D)に天井汚れが発生していたが、 この実施形態に係 る空気調和装置(1)によれば、 空気吹出口(16)の適切な配置構成により、 該空気吹出 口(16)からの空調空気の吹出し方向を水平羽根(18)により天井板(70)下面に対し例え ば 30~35° くらいまで近づけても、 その空気流が天井板 (70)下面に沿って流れる ことは殆どなくなり、 これにより、 従来より課題とされていた天井汚れの発生を防止 することができる。 That is, in the air conditioner of the ceiling-embedded type, in the area where the air blowing speed is low, the airflow tends to approach the lower surface of the ceiling plate (70) due to the Coanda effect, and the horizontal blade (18) during cooling operation. If the direction of the air-conditioning air blow is relatively upward and it is, for example, about 40-45 ° with respect to the lower surface of the ceiling plate (70), the air flow will flow along the lower surface of the ceiling plate (70), and the phantom line in Fig. 2 Although the ceiling dirt was generated in the area (D) as shown by, according to the air conditioner (1) according to this embodiment, the air outlet Even if the direction of air-conditioning air blowing from the mouth (16) is brought close to the lower surface of the ceiling plate (70) by, for example, about 30 to 35 ° by the horizontal blades (18), the air flow along the lower surface of the ceiling plate (70) Flow is almost eliminated, which reduces Can be prevented from occurring.

ここで、 表 1は、 空気吹出口(16)の寸法形状の異なる 4種類の空気調和装置 (夕 イブ 1~4) について、 それぞれ、 この実施形態のようにスぺーサ部材(72)を介して 空気吹出口(16)の配置を調節しながら天井板(70)に取付けた場合と、 該スぺ一サ部材
(72)を用いずに天井板 (70)に取り付けた場合とを対比して、 実際に所定時間運転した 後の天井汚れの発生状況を調べた結果を示したものである。 この実験結果によれば、 空気吹出口(16)の寸法形状によらず、 スぺ一サ部材 (72)を用いることによって、 天井 汚れが発生しない最小吹出し角度を 5〜 1 0° も小さくすることができることが分か る o Here, Table 1 shows that four types of air conditioners (evenings 1 to 4) having different dimensions and shapes of the air outlets (16) are each interposed by a spacer member (72) as in this embodiment. And adjusting the arrangement of the air outlet (16) to the ceiling plate (70), This shows the result of examining the state of occurrence of ceiling dirt after actually operating for a predetermined time in comparison with the case where the apparatus is attached to the ceiling plate (70) without using (72). According to the experimental results, the minimum blowing angle at which ceiling dirt does not occur is reduced by 5 to 10 ° by using the spacer member (72) regardless of the size and shape of the air outlet (16). I know what I can do o
したがって、 この実施形態の空気調和装置(1)によれば、 化粧パネル(14)と天井 板 (70)との間にスぺーサ部材(72)を介設して、 空気吹出口(16)を天井板 (70)に対して 適度に離して配置したことで、 特に空調空気の水平吹出しが要求される冷房運転時に おいて、 天井の汚れを防止しながら、 空調空気の吹出し方向を従来までと比べて水平 方向に近づけることができ、 これにより、 空調効率を確保しかつ室内居住者の違和感 (ドラフト感)を解消できる。 Therefore, according to the air conditioner (1) of this embodiment, the spacer member (72) is provided between the decorative panel (14) and the ceiling plate (70), and the air outlet (16) is provided. By placing the air conditioner at an appropriate distance from the ceiling plate (70), the airflow direction of the air-conditioning air can be maintained at a conventional level while preventing the ceiling from being stained, especially during cooling operation that requires horizontal air-conditioning air blowing. As a result, the air conditioner can be moved closer to the horizontal direction, so that the air conditioning efficiency can be ensured and the sense of inconsistency (draft feeling) for indoor occupants can be eliminated.
また、 天井汚れを防止する要求が低い状況でば、 同じ空気調和装置(1)をスベー サ部材(72)なしで設置することもでき、 こうすることで、 空気調和装置(1)を天井と の一体感が高まるように設置して、 見栄えを向上させることができる。 一変形例一 In addition, if there is a low requirement to prevent ceiling dirt, the same air conditioner (1) can be installed without the spacer member (72), which allows the air conditioner (1) to be connected to the ceiling. It can be installed to enhance the sense of unity and improve the appearance. One modification
図 6は前記実施形態 1の変形例を示し、 この変形例では、 化粧パネル(14)に空気 吹出口(16)の上縁部から斜め下方に向かって延びる突出板(16e)を設けている。 この 場合には、 水平羽根(18)により空調空気の吹出し方向が案内される側の吹出口形成部 材の最下部は、 空気吹出口(16)の上縁部ではなく、 前記突出板(16e)の先端部になる。 従って、 該突出板(16e)の先端部位置から天井板(70)下面までの距離 hを 45mm以 上とするとともに、 該先端部位置から化粧パネル(14)と天井板 (70)との境界位置まで の距離 Lを 9 Omm以上とすれば、 前記実施形態 1と同様の作用効果を得ることがで きる。 FIG. 6 shows a modification of the first embodiment. In this modification, the decorative panel (14) is provided with a projecting plate (16e) extending obliquely downward from the upper edge of the air outlet (16). . In this case, the lowermost part of the outlet forming member on the side where the direction of air-conditioned air is guided by the horizontal blades (18) is not the upper edge of the air outlet (16) but the protruding plate (16e). ). Therefore, the distance h from the position of the tip of the protruding plate (16e) to the lower surface of the ceiling plate (70) is 45 mm or more, and the boundary between the decorative panel (14) and the ceiling plate (70) from the position of the tip. When the distance L to the position is set to 9 Omm or more, the same operation and effect as in the first embodiment can be obtained.

図 7は本発明に係る天井埋込型空気調和装置(1)の実施形態 2を示し、 この実施
形態 2に係る空気調和装置(1)は、 空気吹出口(16)等の詳細な構成を除いて、 前記実 施形態 1のものと同じものなので、 以下、 同一部材には同一の符号を付して詳しい説 明は省略する。 そして、 この実施形態 2の主たる特徴部分は、 前記実施形態 1と同じ く空気調和装置(1)の化粧パネル(14)と天井板(70)との間にスぺーサ部材 (72)を介設 して、 空気吹出口(16)の上縁部を天井板(70)下面から適度に離して配置したことに加 えて、 その空気吹出口(16)から吹出す空気流ができるだけ上向きにならないように、 また、 その空気流の一部が上向きに流れても、 その空気中に含まれる塵埃によって天 井板 (70)下面が汚れないように、 空気吹出口(16)よりも外側の化粧パネル(14)の寸法 形状を設定したことにある。 FIG. 7 shows a second embodiment of the ceiling-mounted air conditioner (1) according to the present invention. The air conditioner (1) according to the second embodiment is the same as that of the first embodiment except for a detailed configuration such as an air outlet (16). Hereinafter, the same members are denoted by the same reference numerals. And a detailed explanation is omitted. The main characteristic part of the second embodiment is that a spacer member (72) is provided between the decorative panel (14) of the air conditioner (1) and the ceiling plate (70), as in the first embodiment. In addition to arranging the upper edge of the air outlet (16) at an appropriate distance from the lower surface of the ceiling plate (70), the airflow blown out of the air outlet (16) is not as upward as possible In addition, even if a part of the airflow flows upward, the outer surface of the ceiling plate (70) is not stained by dust contained in the air, so that the outer surface of the ceiling plate (70) is not stained. This is in setting the dimensions and shape of the panel (14).
詳しくは、 化粧パネル(14)における空気吹出口(16)よりも外側、 即ち水平羽根(1 8)により空調空気の吹出し方向が案内される側には、 該空気吹出口(16)の上縁部から 空調装置ケ一シング(10)の外周側に向かって天井板 (70)下面に近づくように傾斜する 略平面形状の外部傾斜面(14a)が設けられていて、 この外部傾斜面(14a)の天井面に対 する傾斜角度 6>は 10° 以上 (好ましくは 10. 8度) とされている。 このことで、 冷房運転時等に空気吹出口(16)から吹出された空気流 (噴流) は、 まず化粧パネル(1 4)の外部傾斜面(14a)との間のコアンダ効果によって上向きに曲げられるが、 この外 部傾斜面(14a)の傾斜状態の設定によりコアンダ効果を緩和して、 空調空気の上向き の流れを弱めることができる。 More specifically, on the outer side of the air outlet (16) of the decorative panel (14), that is, on the side where the direction of air-conditioning air is blown out by the horizontal blades (18), the upper edge of the air outlet (16) is provided. A substantially planar outer inclined surface (14a) is provided which is inclined from the portion toward the outer peripheral side of the air conditioner casing (10) so as to approach the lower surface of the ceiling plate (70). The angle of inclination 6> with respect to the ceiling surface is set to 10 ° or more (preferably 10.8 °). As a result, the air flow (jet flow) blown out from the air outlet (16) during cooling operation or the like is first bent upward by the Coanda effect between the externally inclined surface (14a) of the decorative panel (14). However, by setting the inclined state of the outer inclined surface (14a), the Coanda effect can be reduced and the upward flow of the conditioned air can be reduced.
また、 前記空気吹出口(16)上縁部と天井板 (70)下面との間の上下方向間隔 hは、 前記実施形態 1と同じく 45mm以上に設定されており、 さらに、 該空気吹出口(16) 上縁部はスぺーサ部材(72)の外周端部から水平方向に十分に離れるように配置されて いて、 言い換えると、 空気吹出口(16)上縁部と空気調和装置(1)及び天井板(70)の境 界位置との間の水平方向距離 Aが 75 mm以上 (好ましくは 79mm) に設定されて いる。 このことで、 空気吹出口(16)から吹き出された空調空気の一部が上向きに流れ、 その後、 化粧パネル(14)の外部傾斜面(14a)に沿って流れても、 その空気吹出口(16) の上縁部が天井板( 70 )との境界位置から水平方向に十分に離れているので、 化粧パネ ル(14)に沿って流れる空気流の殆どは天井板 (70)下面にまで達する前に下降するよう
になる。 The vertical interval h between the upper edge of the air outlet (16) and the lower surface of the ceiling plate (70) is set to 45 mm or more as in the first embodiment. 16) The upper edge is disposed sufficiently horizontally in the horizontal direction from the outer peripheral end of the spacer member (72). In other words, the upper edge of the air outlet (16) and the air conditioner (1) And the horizontal distance A from the boundary position of the ceiling plate (70) is set to 75 mm or more (preferably 79 mm). As a result, even if a part of the conditioned air blown out from the air outlet (16) flows upward and then flows along the outer inclined surface (14a) of the decorative panel (14), the air outlet ( 16) Since the upper edge of the ceiling panel (70) is sufficiently far from the boundary with the ceiling panel (70) in the horizontal direction, most of the airflow flowing along the decorative panel (14) reaches the bottom of the ceiling panel (70). To descend before reaching become.
加えて、 この実施形態 2では、 前記実施形態 1の水平羽根(18)に代えて、 例えば 図 8に示すような整流板(19, 19,···)を備えた水平羽根(18)を用いている。 この水平羽 根(18)は、 幅方向に亘つて僅かに湾曲された長尺の板部材からなり、 その湾曲する内 側の面(18a)が前面とされ、 また外側の面(18b)が背面とされている。 さらに、 水平羽 根(18)の長手方向両端部にはそれぞれ前面側に突出する貝殻状の突出部(18c, 18c)が 一体的に設けられ、 該各突出部(18c)端にそれぞれ水平羽根(18)の長手方向に沿って 外方に延びるように連結ピン(18d、18d)が形成されている。 そして、 前記水平羽根(1 8)は、 前記図 7に示すように空気吹出口(16)に配置された状態で、 該空気吹出口(16) の奥側 (空調空気の流れの上流側:図の左側) に位置する前記 2つの連結ピン(18d,l 8d)が化粧カバー(14)側の連結部材(14b)により回動自在に連結支持されていて、 これ により、 水平羽根(18)は図示しないモー夕の駆動によって、 支持軸 Xを回動中心とし て上下に回動されるようになっている。 In addition, in the second embodiment, in place of the horizontal blade (18) of the first embodiment, for example, a horizontal blade (18) having a current plate (19, 19,...) As shown in FIG. Used. The horizontal blade (18) is composed of a long plate member slightly curved in the width direction, the curved inner surface (18a) is the front surface, and the outer surface (18b) is the outer surface (18b). The back has been. Further, shell-like projections (18c, 18c) protruding toward the front side are integrally provided at both ends in the longitudinal direction of the horizontal blade (18), and the horizontal blades (18c) are respectively provided at ends of the respective projections (18c). The connection pins (18d, 18d) are formed to extend outward along the longitudinal direction of (18). The horizontal blades (18) are arranged at the air outlets (16) as shown in FIG. 7, and are located at the inner side of the air outlets (16) (upstream of the flow of the conditioned air: The two connecting pins (18d, l8d) located on the left side of the figure are rotatably connected and supported by a connecting member (14b) on the decorative cover (14) side, whereby the horizontal blade (18) Is rotated up and down around the support shaft X by the drive of a motor (not shown).
また、 前記水平羽根(18)の内側に湾曲する前面(18a)上には、 該水平羽根(18)の 長手方向全体に亘つて互いに所定間隔を空けて、 空調空気の流れを整流するための複 数の整流板(19,19,···:図例では 1 0枚)が固定配置されている。 この各整流板(19)は、 水平羽根(18)の前面(18a)に略直交するように該水平羽根(18)の幅方向に亘つて配置 されており、 図に矢印 Sで示すように、 水平羽根(18)の前面(18a)に沿って流れる空 調空気は、 各整流板(19)の間を流れる間に水平羽根(18)の長手方向全体に亘つて整流 される。 このように整流板(19, 19,···)によって整流された空気流は概ね鉛直面に沿う 2次元流になるので、 空気吹出口(16)から吹出される空調空気の吹出し初速度は、 該 空気吹出口(16)の両側部分でも中央部分と同様に高くなる。 したがって、 この実施形態 2の空気調和装置(1)では、 前記実施形態 1と同様に スぺーサ部材 (72)を用いて、 空気吹出口(16)の上縁部を天井板 (70)下面から上下方向 に適度に離して配置したことに加えて、 該空気吹出口(16)の上縁部を天井板(70)との 境界位置から水平方向に十分に離して配置し、 かっこの空気吹出口(16)上縁部に連な
る化粧パネル(14)の外部傾斜面(14a)を水平面に対し比較的大きく傾斜する形状とし たことで、 空調空気の水平吹出し状態において、 まず、 空気吹出口(16)から吹き出さ れる空気流が上向きに曲げられることを抑制でき、 さらに、 化粧パネル(14)に沿って 上向きに流れる一部の空気流を天井板(70)下面に達する前に下降させることができる ので、 空気中に含まれる塵埃による天井面の汚れを実施形態 1よりもさらに効果的に 防止することができる。 On the front surface (18a) curved inside the horizontal blade (18), a predetermined interval is provided between the horizontal blade (18) over the entire longitudinal direction of the horizontal blade (18) to rectify the flow of conditioned air. A plurality of rectifying plates (19, 19, ...: 10 in the example in the figure) are fixedly arranged. Each of the rectifying plates (19) is disposed across the width direction of the horizontal blade (18) so as to be substantially orthogonal to the front surface (18a) of the horizontal blade (18). The conditioned air flowing along the front surface (18a) of the horizontal blade (18) is rectified over the entire longitudinal direction of the horizontal blade (18) while flowing between the respective rectifying plates (19). Since the air flow rectified by the flow straightening plates (19, 19, ...) becomes a two-dimensional flow generally along the vertical plane, the initial velocity of the conditioned air blown out from the air outlet (16) is However, both sides of the air outlet (16) are as high as the central part. Therefore, in the air conditioner (1) of the second embodiment, the upper edge of the air outlet (16) is fixed to the lower surface of the ceiling plate (70) by using the spacer member (72) as in the first embodiment. In addition to the air outlet (16) being placed at an appropriate distance in the vertical direction, the upper edge of the air outlet (16) is placed sufficiently far in the horizontal direction from the boundary with the ceiling plate (70). Outlet (16) connected to the upper edge The exterior inclined surface (14a) of the decorative panel (14) has a shape that is relatively inclined to the horizontal plane, so that the airflow blown out from the air outlet (16) can be achieved first when the conditioned air is blown horizontally. Is prevented from being bent upward, and a part of the airflow flowing upward along the decorative panel (14) can be lowered before reaching the lower surface of the ceiling plate (70), so that the airflow is included in the air. It is possible to more effectively prevent the ceiling surface from being contaminated by dust that is generated.
また、 この実施形態 2では、 水平羽根(18)に整流板(19,19,···)を設けて、 空調空 気の流れを整流するようにしたので、 空気吹出口( 16 )の両側部分における吹出し空気 流速の低下を殆ど解消し、 この部分で空気流が上向きになることを抑制して、 前記の 作用効果をより一層、 高めることができる。 一その他の実施の形態— Also, in the second embodiment, the rectifying plates (19, 19,...) Are provided on the horizontal blades (18) to rectify the flow of the air-conditioned air. The decrease in the flow velocity of the blown air in the portion is almost eliminated, and the upward flow of the air is suppressed in this portion, so that the above-described operation and effect can be further enhanced. Another embodiment—
尚、 本発明は前記実施形態 1及び 2に限定されず、 その他の種々の実施形態を包 含するものである。 すなわち、 前記各実施形態では、 化粧パネル(14)と天井板 (70)と の間にスぺ一サ部材(72)を介設して、 空気吹出口(16)の位置を調節するようにしたが、 これに限らず、 予め化粧パネル(14)の上下方向寸法を大きくして、 スぺーサ部材(72) を用いずに、 空気吹出口(16)を天井板(70)下面から適度に離して配置するようにして もよい。 It should be noted that the present invention is not limited to the first and second embodiments, but includes other various embodiments. That is, in each of the above embodiments, a spacer member (72) is interposed between the decorative panel (14) and the ceiling plate (70) to adjust the position of the air outlet (16). However, the present invention is not limited to this, and the vertical size of the decorative panel (14) is increased in advance, and the air outlet (16) can be appropriately moved from the lower surface of the ceiling plate (70) without using the spacer member (72). It may be arranged away from the camera.
また、 前記各実施形態では、 空気吹出口(16)に水平羽根(18)を配設して、 空調空 気の流れを上下に変更するようにしているが、 この水平羽根(18)は設けずに、 空気吹 出口(16)に至る空気通路の湾曲形状のみによって、 空調空気の流れを案内するように してもよい。 この場合には、 空気通路そのものが案内手段を構成する。 Further, in each of the above embodiments, the horizontal blade (18) is provided at the air outlet (16) to change the flow of the air-conditioning air up and down. However, the horizontal blade (18) is provided. Instead, the flow of the conditioned air may be guided only by the curved shape of the air passage leading to the air outlet (16). In this case, the air passage itself constitutes the guiding means.
さらに、 前記実施形態 1の空気調和装置(1)では、 空気吹出口(16)上縁部と天井 板(70)下面との間の上下方向間隔 hを特定し、 また、 実施形態 2の空気調和装置(1) では、 これに加えて、 空気吹出口(16)上縁部から空調装置ケーシング (10)の天井板(7 0)との境界位置までの水平距離 Aや化粧パネル外部傾斜面(14a)の傾斜角度 0を特定 しているが、 これに限るものではない。 すなわち、 例えば、 前記水平距離 A又は傾斜
角度 0のいずれか一方のみを特定することで、 前記各実施形態と同様に天井汚れの発 生を大幅に軽減できる。 或いはまた、 前記上下方向間隔 h及び水平距離 A、 上下方向 間隔 h及び傾斜角度 θ、 又は水平距離 Α及び傾斜角度 6»のいずれか 1組を特定するこ とで、 前記各実施形態と同様に天井汚れの発生を殆ど防止することが可能になる。 Further, in the air conditioner (1) according to the first embodiment, the vertical interval h between the upper edge of the air outlet (16) and the lower surface of the ceiling plate (70) is specified.
