Description

【０００１】
【発明の属する技術分野】
この発明は、埋め込み形空気調和機の室内ユニットに係り、特にその風路に関するものである。
説明の便宜上、以下の説明は天井埋め込み形空気調和機の室内ユニットについて行う。
【０００２】
【従来の技術】
従来例１．
図７は従来の天井埋め込み形空気調和機の室内ユニットの断面図、図８は同吹き出し側風路での風の風速分布を示す概略図である。図において、１はユニット本体、２は空調空間の空気を吸い込む吸込口、３は吸い込んだ空気を熱交換する吸込口２より下流に位置する熱交換器、４は熱交換器３より下流に位置して送風作用を行う貫流送風機、７は送風機４により吸い込んだ空気を吹き出す吹出口で、吸込口２と同一面となっている。５は熱交換器３と送風機４の間に位置する吸い込み側風路、６は送風機４と吹出口７の間に位置して吸い込み側風路５とつながる、形状がある一定の関数にて形成され吹き出し側風路、８は吹出口７に設けた吹き出す風を上下方向に偏向する上下フラップ、９は吹出口７に設けた左右方向に偏向する左右ルーバである。
【０００３】
次に動作を説明する。
貫流送風機４が回転し、その送風作用により吸込口２から吸い込まれ空調空間の空気は熱交換器３を通過して熱交換され、吸い込み側風路５を経て送風機４内を通過し吹き出し側風路６から吹出口７へと流れ、上下フラップ８及び左右ルーバ９により偏向されて再度空調空間へと吹き出されることになる。
【０００４】
ここで貫流送風機４を通過した風は吹き出し側風路６内で風路（風の流れ）と交差する方向に図８に示すようにＸ方向に不均一な風速分布となっている。ここで天井カセット形空気調和機はユニットが天井内に隠蔽されることから、吸込口２と吹出口７が同一面となり吹き出し側風路６が長く、また送風機４を通過した風を９０度方向を変える必要があるため、吸い込み側風路だけでなく吹き出し側風路を改善する必要がある。
【０００５】
従来例２．
図９は例えば特公平５−２４８６５２号公報に示された他の従来の空気調和機の断面図である。図において、１３は吸い込み側風路に設けたバックノーズ、２０は空気流路である。その他は図７と同一である。
【０００６】
吸込口２より吸い込まれた空調空間の空気は、送風機４による送風作用で熱交換器３で熱交換された後、吸い込み側風路５・バックノーズ１２から吹き出し側風路６を通過して吹出口７より吹き出され、その際上下フラップ８によって風向を偏向される。
【０００７】
そして、送風機４の上流側の吸い込み側風路５にて発生する逆流などの乱れをバックノーズ１３に発生させ、最小限にすることによって騒音を減少させ効率の良い送風運転を行うことを目的としたものである。
【０００８】
従来例３．
また、シロッコファンを使用した室内ユニットにおいて、吹き出し側風路内の屈曲部の内側に近い位置に空気流の一部を強制的に内側方向に曲げるための導風板を設けたものが実開平１−７００３４号公報に開示されている。
【０００９】
従来例４．
また、吹出口の本体枠を覆蓋するように断熱部材を備えることにより結露を防止し、吹出口内に風向調整用の羽枠を吊支することも可能なものが実開平７−２６６４５号公報に開示されている。
【００１０】
【発明が解決しようとする課題】
従来の空気調和機は以上のように構成されているので、次のような問題があった。
（１）吹き出し側風路６の形状がある一定の関数にて形成されていたが、天井カセット形空気調和機においては室内ユニットが天井内に隠蔽されることから、吸込口２と吹出口７が同一面となり吹き出し側風路６が長くなるため、従来の形状では吹き出し側風路の風路（風の流れ方向）と交差する方向の風速分布が均一とならず送風運転の効率が悪くなるという問題点があった。
【００１１】
（２）吹出口７でも上下方向の風速が均一とならないため上下方向の風向が偏向しにくい、吹出口７での風の巻き込みが発生して冷房・ドライ運転時には着露に至るという問題点があった。
【００１２】
（３）吸込口２から吸い込まれ熱交換器３を通過した後、送風機４に入る際に貫流送風機４には連結部があるため、その影響で送風機４の軸方向で不均一に吸い込まれ、その後不均一のまま吹き出し側風路６を通過して吹出口７より吹き出されるため、送風運転の効率が悪くなりサージング耐力が低くなり、逆吸い込みの発生により冷房・ドライ運転時には着露に至るという問題点があった。
【００１３】
（４）吹出口でも左右方向の風速が均一とならないため左右方向の風向が偏向しにくいという問題点があった。
【００１４】
（５）吹出口７端部においては風速が遅く、左右ルーバ９の使用位置によっては風の巻き込みが発生し、冷房・ドライ運転時には吹出口７周囲が着露に至るという問題があり、左右風向の偏向調整位置が制限されるという問題点があった。
【００１５】
この発明は、上記のような問題点を解消するためになされたもので、効率の良い送風運転の実現、吹出口から吹き出す風の風速分布の均一化、風向の偏向性の改善、吹出口周囲の着露の防止を図ることの出来る埋め込み形空気調和機の室内ユニットを得ることを目的とする。
【００１６】
【課題を解決するための手段】
この発明に係る埋め込み形空気調和機の室内ユニットは、室内ユニット本体と、本体に設けられ、空調空間の空気を吸い込む吸込口と、吸込口の下流に位置し、吸い込んだ空気を熱交換する熱交換器と、熱交換器の下流に位置する送風機と、送風機から送り出された空気を吹き出す吹出口と、送風機と吹出口との間に位置する吹き出し側風路と、吹き出し側風路の送風機から風の流れを曲げるまでの区間に設けられ、規則的な拡大幅よりも風路幅を一旦拡げて風速分布を均一化する風速分布均一化手段とを備え、吹き出し側風路は、風速分布均一化手段の下流において風路幅を狭めた後、吹出口まで徐々に拡大していくことを特徴とする。
【００２０】
また、この発明に係る埋め込み形空気調和機の室内ユニットは、室内ユニット本体と、本体に設けられ、空調空間の空気を吸い込む吸込口と、吸込口の下流に位置し、吸い込んだ前記空気を熱交換する熱交換器と、熱交換器の下流に位置する送風機と、送風機から送り出された空気を吹き出す吹出口と、熱交換器と送風機との間に位置する吸い込み側風路と、送風機と吹出口との間に位置する吹き出し側風路と、吹出口に設けられ、吹き出す空気を左右方向に偏向する左右ルーバと、吹出口の端部と平行に設けられ、吹出口の端部との間から空気を吹出口に対して直角に吹き出し、左右ルーバを介して吹き出される空気を吹出口に対して直角方向に誘導する誘導手段とを備えたことを特徴とする。
【００２１】
【発明の実施の形態】
実施の形態１．
以下、この発明の実施の形態１による天井埋め込み形空気調和機の室内ユニットを図について説明する。図１はこの発明の実施の形態１による天井埋め込み形空気調和機の室内ユニットの断面図、図２は同吹き出し側風路での風の風速分布を示す概略図である。
【００２２】
図において、１５は、送風機４直後から風を曲げるまでの区間Ａで、規則的な拡大幅よりも風路幅を一旦拡げて風速分布を均一化する風速分布均一化手段である整流部風路である。その他は従来例１と同一であり、説明は省略する。
【００２３】
次に動作を説明する。
送風機４を通過したＸ方向に不均一な風速分布を有する風を、吹き出し側風路６全体を従来のようにある一定の規則的に拡大していく形状とはせずに、送風機４直後から風を曲げるまでの区間Ａで、規則的な拡大幅よりも風路幅を一旦拡げて風速分布を均一化する整流部風路１５を設けてから狭めた後、吹出口７まで徐々に拡大していくことにより、風速分布の均一化を図った後で風を曲げることで、吹き出し側風路６内に強制的に風を曲げるための導風板を設けることなく効率的に風を曲げることが出来、吹き出し側風路６内及び吹出口７から吹き出される風の風速を均一化することが出来る。
【００２４】
その結果、効率の良い送風運転によるユニットの静音化等の空力性能の向上が可能となる。また更に効果として吹出口７より吹き出される風が均一となることから、上下方向の風向の偏向性の改善、及び吹出口７での風の巻き込みの発生防止により冷房・ドライ運転時の吹出口７周囲への着露を防止することが可能となる。
【００２５】
実施の形態２．
以下、この発明の実施の形態２による天井埋め込み形空気調和機の室内ユニットを図について説明する。図３はこの発明の実施の形態２による天井埋め込み形空気調和機の室内ユニットの断面図、図４は同要部平面図である。
図において、１０は吸い込み側風路５に送風機４の連結部に合わせて１枚から複数枚設置された整流手段である吸い込み側整流板、１１は吹き出し側風路６に送風機４の連結部に合わせて１枚から複数枚設置された整流手段である吹き出し側整流板である。
【００２６】
貫流送風機４には軸方向に連結部があるため、吸い込み側風路５に送風機４の連結部に合わせて１枚から複数枚の吸い込み側整流板１０、及び吹き出し側風路６に送風機４の連結部に合わせて１枚から複数枚の吹き出し側整流板１１を設置することにより、送風機４に吸い込まれる時と吹き出される時の両方で整流することにより、送風機４を通過する際の送風機４の軸直角方向での風の乱れを防ぎ風の流れを均一化することが出来る。その結果、効率の良い送風運転によるユニットの静音化等の空力性能の向上が可能となる。また送風機４の軸直角方向の風の流れが均一化されることにより、吹出口７の左右方向の風の流れが均一となるため左右ルーバ９による風向の偏向性の改善、及びサージングによる冷房・ドライ運転時の吹出口７周囲・送風機４への着露を防止することが可能となる。
【００２７】
実施の形態３．
以下、この発明の実施の形態３による天井埋め込み形空気調和機の室内ユニットを図について説明する。図５はこの発明の実施の形態３による天井埋め込み形空気調和機の室内ユニットの要部断面図、図６は同吹出口部風向概略図である。図において、１２は吹出口の左右ルーバ９の近傍に設けた左右ルーバ９を介して吹き出される風を所定方向に誘導する誘導手段である案内板である。
【００２８】
吹出口９に案内板１２を設けることにより、吹出口７の端部において風速が遅くなるのを防ぎ、また案内板１２を吹出口７の端部と平行に配置することで吹出口端部と案内板１２の間からは風が吹出口７に対して直角に吹き出され、その風の効果により左右ルーバ９の使用位置による風の巻き込みが発生することがなく、吹出口７周囲への着露を防止することが出来る。
また、左右ルーバ９の偏向調整を着露防止から制限されることなく風向の偏向幅を拡大することが可能となる。
更に吹出口７の外枠を覆蓋するように断熱部材を備えることなく吹出口７周囲への着露を防止することが可能となる。
【００２９】
【発明の効果】

BACKGROUND OF THE INVENTION
The present invention relates to an indoor unit of an embedded air conditioner, and more particularly to its air path.
For convenience of explanation, the following explanation will be given for an indoor unit of a ceiling-embedded air conditioner.
[0002]
[Prior art]
Conventional Example 1
FIG. 7 is a cross-sectional view of an indoor unit of a conventional ceiling-embedded air conditioner, and FIG. 8 is a schematic view showing the wind speed distribution in the air outlet side air passage. In the figure, 1 is a unit body, 2 is a suction port for sucking air in the air-conditioned space, 3 is a heat exchanger located downstream from the suction port 2 for exchanging heat of the sucked air, and 4 is located downstream from the heat exchanger 3. The once-through blower 7 that performs the blowing action is a blowout port that blows out the air sucked by the blower 4, and is flush with the suction port 2. 5 is a suction side air passage located between the heat exchanger 3 and the blower 4, and 6 is formed between the blower 4 and the outlet 7 and connected to the suction side air passage 5, and is formed by a certain function having a shape. Reference numeral 8 denotes an air outlet side air passage, 8 is an upper and lower flap for deflecting the blown air provided in the air outlet 7 in the vertical direction, and 9 is a left and right louver provided in the air outlet 7 for deflecting in the left and right direction.
[0003]
Next, the operation will be described.
The once-through fan 4 rotates and is sucked in from the suction port 2 by the blowing action, and the air in the air-conditioned space passes through the heat exchanger 3 and is heat-exchanged. The air flows from the path 6 to the air outlet 7, is deflected by the upper and lower flaps 8 and the left and right louvers 9, and is blown out again into the air-conditioned space.
[0004]
Here, the wind that has passed through the once-through blower 4 has a non-uniform wind speed distribution in the X direction as shown in FIG. 8 in the direction intersecting the wind path (wind flow) in the blow-out side wind path 6. Here, in the ceiling cassette type air conditioner, since the unit is concealed in the ceiling, the suction port 2 and the blowout port 7 are flush with each other, the blowout side air passage 6 is long, and the wind that has passed through the blower 4 is directed by 90 degrees. Therefore, it is necessary to improve not only the suction side air passage but also the blowout side air passage.
[0005]
Conventional Example 2
FIG. 9 is a cross-sectional view of another conventional air conditioner disclosed in, for example, Japanese Patent Publication No. 5-248652. In the figure, 13 is a back nose provided in the suction side air passage, and 20 is an air passage. Others are the same as FIG.
[0006]
The air in the air-conditioned space sucked from the suction port 2 is heat-exchanged by the heat exchanger 3 by the blowing action of the blower 4 and then blown from the suction-side air passage 5 and the back nose 12 through the blowing-side air passage 6. The air is blown out from the outlet 7, and the wind direction is deflected by the upper and lower flaps 8 at that time.
[0007]
The purpose of the present invention is to generate a disturbance such as a backflow generated in the suction side air passage 5 upstream of the blower 4 in the back nose 13 and to minimize the noise, thereby performing an efficient blowing operation. It is a thing.
[0008]
Conventional Example 3
An indoor unit using a sirocco fan is provided with a wind guide plate for forcibly bending a part of the air flow inward at a position close to the inside of the bent part in the blowout side air passage. 1-70034.
[0009]

[0010]
[Problems to be solved by the invention]
Since the conventional air conditioner is configured as described above, it has the following problems.
(1) Although the shape of the blow-out side air passage 6 is formed by a certain function, in the ceiling cassette type air conditioner, the indoor unit is concealed in the ceiling. Since the blowout side air passage 6 becomes longer on the same surface, the conventional shape does not have a uniform wind speed distribution in the direction intersecting the air passage (wind flow direction) of the blowout side air passage, and the efficiency of the air blowing operation is deteriorated. There was a problem.
[0011]
(2) The vertical wind speed is not uniform even at the air outlet 7, so that the vertical air direction is difficult to deflect, and wind is entrained at the air outlet 7, resulting in dew condensation during cooling / dry operation. there were.
[0012]
(3) After passing through the heat exchanger 3 after being sucked from the suction port 2, the cross-flow fan 4 has a connecting portion when entering the fan 4, so that the influence is sucked non-uniformly in the axial direction of the fan 4, After that, the air passes through the blow-out side air passage 6 and is blown out from the blow-out port 7, so that the efficiency of the air blowing operation is deteriorated and the surging proof strength is lowered, and the occurrence of reverse suction leads to dew condensation during the cooling / dry operation. There was a problem.
[0013]
(4) Since the wind speed in the left-right direction is not uniform even at the air outlet, there is a problem that the wind direction in the left-right direction is difficult to deflect.
[0014]
(5) There is a problem that the wind speed is slow at the end of the air outlet 7, wind may be trapped depending on the use position of the left and right louvers 9, and there is a problem that the periphery of the air outlet 7 is dewed during cooling / dry operation. There is a problem in that the deflection adjustment position of the head is limited.
[0015]
The present invention has been made to solve the above-described problems, and realizes an efficient air blowing operation, uniforming the wind speed distribution of the wind blown from the air outlet, improving the deflectability of the air direction, and surrounding the air outlet An object of the present invention is to provide an indoor unit of an embedded air conditioner that can prevent the dew condensation.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
Hereinafter, an indoor unit of a ceiling-embedded air conditioner according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of an indoor unit of a ceiling-embedded air conditioner according to Embodiment 1 of the present invention, and FIG. 2 is a schematic diagram showing the wind speed distribution in the air outlet side air passage.
[0022]
In the figure, reference numeral 15 denotes a section A immediately after the blower 4 until the wind is bent, and a rectifying section air passage which is a wind speed distribution uniformizing means for temporarily expanding the air passage width rather than the regular expansion width to make the air speed distribution uniform. It is. Others are the same as the prior art example 1, and a description thereof is omitted.

Next, the operation will be described.
The wind having a non-uniform wind speed distribution in the X direction that has passed through the blower 4 is not formed into a certain regular and regular expansion shape on the blowout side air passage 6 as in the prior art, but immediately after the blower 4. In the section A until the wind is bent, after the air passage width 15 is temporarily expanded rather than the regular expansion width and the rectifying section air passage 15 for uniforming the wind speed distribution is provided and then narrowed, it is gradually expanded to the air outlet 7. As a result, the wind is bent after uniforming the wind speed distribution, so that the wind can be efficiently bent without providing a wind guide plate for forcibly bending the wind in the blowout side air passage 6. Thus, the wind speed of the wind blown out from the blowout side air passage 6 and the blowout port 7 can be made uniform.
[0024]

Further, since the air blown out from the air outlet 7 becomes uniform as an effect, the air outlet at the time of cooling / dry operation is improved by improving the deflectability of the wind direction in the vertical direction and preventing the occurrence of the entanglement of the air at the air outlet 7. 7 It becomes possible to prevent dew condensation around.
[0025]
Embodiment 2. FIG.

Since the cross flow blower 4 has a connecting portion in the axial direction, one to a plurality of suction side rectifying plates 10 and a blower side air passage 6 are connected to the suction side air passage 5 in accordance with the connection portion of the blower 4. The blower 4 when passing through the blower 4 by rectifying both when sucked into the blower 4 and when blown out by installing one to a plurality of blowout side rectifying plates 11 according to the connecting portion. Wind disturbance in the direction perpendicular to the axis can be prevented and the flow of wind can be made uniform. As a result, it is possible to improve aerodynamic performance such as noise reduction of the unit by efficient air blowing operation. Further, since the flow of air in the direction perpendicular to the axis of the blower 4 is made uniform, the flow of wind in the left and right direction of the air outlet 7 is made uniform, so that the right and left louvers 9 improve the deflection of the wind direction, and cooling by cooling It becomes possible to prevent dew condensation around the blower outlet 7 and the blower 4 during the dry operation.
[0027]
Embodiment 3 FIG.
Hereinafter, an indoor unit of a ceiling-embedded air conditioner according to Embodiment 3 of the present invention will be described with reference to the drawings. FIG. 5 is a sectional view of the main part of an indoor unit of a ceiling-embedded air conditioner according to Embodiment 3 of the present invention, and FIG. In the figure, reference numeral 12 denotes a guide plate which is a guiding means for guiding the wind blown through the left and right louvers 9 provided in the vicinity of the left and right louvers 9 at the outlet.
[0028]
Providing the guide plate 12 at the outlet 9 prevents the wind speed from slowing at the end of the outlet 7, and disposing the guide plate 12 in parallel with the end of the outlet 7 Wind is blown out from between the guide plates 12 at a right angle to the air outlet 7, and the wind effect prevents the wind from being caught by the use position of the left and right louvers 9, and the dew around the air outlet 7. Can be prevented.
Further, the deflection width of the wind direction can be increased without restricting the deflection adjustment of the left and right louvers 9 from the prevention of dew condensation.
Furthermore, it becomes possible to prevent dew condensation around the air outlet 7 without providing a heat insulating member so as to cover the outer frame of the air outlet 7.
