Description

本発明は、空気調和装置に関する。   The present invention relates to an air conditioner.

従来の空気調和装置においては、停止時には吹出部を閉じ、運転時には吹出部を開くように上下風向板が設けられている。   In a conventional air conditioner, an up-and-down wind direction plate is provided so as to close the blowing part when stopped and to open the blowing part during operation.

特に最近の空気調和装置においては、室内機の設置空間への調和や意匠性を向上させるために、実際の吹出口よりも横幅が広い上下風向板が設けられたものが提案されている。   In particular, recent air conditioners have been proposed in which an up-and-down wind direction plate having a wider width than an actual air outlet is provided in order to improve harmony and design of an indoor unit.

例えば特許文献1のように、上下風向板の回転軸とその駆動装置の回転軸をずらして設置し、さらに上下風向板の回転軸とその駆動装置の回転軸とを結合する駆動機構を備えたものが開示されており、室内機の意匠性を向上させるだけでなく、室内水平方向の送風幅を拡大して、室内の送風分布を改善することができるという効果がある。   For example, as disclosed in Patent Document 1, a rotation mechanism for shifting the rotation axis of the vertical wind direction plate and the rotation axis of the drive device thereof is installed, and a drive mechanism for coupling the rotation axis of the vertical wind direction plate and the rotation shaft of the drive device is provided. In addition to improving the design of the indoor unit, there is an effect that the ventilation width in the room can be expanded to improve the distribution of the ventilation in the room.

一方、空気調和装置では一般に、暖房運転時には暖かい空気を足元に向けるように、吹出口の上下風向板を下向きにし、冷房運転時は上下風向板をほぼ水平にして、冷えた空気が顔や頭の近くを流れるようにして快適性を確保している。これは、自然対流で暖かい空気は上に、冷たい空気は下に向かうので、前記のようにすることにより、室内全体に暖房/冷房効果が行き渡り、快適な室内になるためである。   On the other hand, in an air conditioner, in general, the vertical airflow direction plate of the air outlet is directed downward so that warm air is directed toward the feet during heating operation, and the vertical airflow direction plate is substantially horizontal during cooling operation so that the chilled air flows into the face and head. The comfort is ensured by flowing near. This is because natural convection warm air goes up and cold air goes down, so that the heating / cooling effect is spread throughout the room and the room becomes comfortable.

このとき、特に冷房運転において、周囲空気と吹出し空気の接する箇所である上下風向板の端部や吹出口の出口端部で、高湿空気が周囲温度より低い固体表面で冷却され、結露を生じることがある。結露は、長時間運転により滴下する恐れがあり、ユーザーにとって重大なクレームとなる。これを防止するため、結露を生じる恐れのあると箇所に吸湿効果のある部材を貼付したり、周囲部材と断熱する部材で構成するのが一般的であるが、ほかに、特許文献2のように吹出口に設けられた上下風向板を下向きにした状態で吹出口に補助風向板を下向きに固定又は回転可能に設けることで、結露を防止しているものもある。   At this time, especially in the cooling operation, the humid air is cooled on the solid surface lower than the ambient temperature at the end of the up-and-down wind direction plate and the outlet end of the blow-out port where the ambient air and the blow-out air are in contact with each other, resulting in condensation. Sometimes. Condensation may be dripped by long-time operation, which is a serious complaint for users. In order to prevent this, it is common to attach a member having a hygroscopic effect to a place where there is a possibility of causing condensation, or a member that insulates from the surrounding member. In some cases, dew condensation is prevented by providing an auxiliary wind direction plate that is fixed downward or rotatable downward at the air outlet with the vertical air direction plate provided at the air outlet facing downward.

特開2002−106948号公報JP 2002-106948 A 特開平7−77351号公報Japanese Patent Laid-Open No. 7-77351

しかしながら、特許文献1に記載の上下風向板と駆動装置の構成では、上下風向板の回転軸とその駆動装置の回転軸が風路の内側にあることで通風抵抗の増大が懸念される。   However, in the configuration of the up-and-down air direction plate and the driving device described in Patent Document 1, there is a concern that the ventilation resistance increases because the rotation axis of the up-and-down air direction plate and the rotation axis of the driving device are inside the air path.

また、吹出口の出口端部などの冷風による露付きを防止するため、吸湿効果のある別部材を利用すると、使用時にその別部材がユーザーに見えることで意匠性を損なったり、コストが増大する。あるいは、特許文献2に記載の構成で露付きを防止できたとしても、吹出口よりも横幅が長い上下風向板を本体外形に干渉することなく構成することができない。   Moreover, in order to prevent dew condensation due to cold air, such as the outlet end of the blower outlet, if another member having a moisture absorption effect is used, the separate member can be seen by the user at the time of use, resulting in a loss of design or an increase in cost. . Or even if it can prevent dew condensation with the composition of patent documents 2, it cannot constitute an up-and-down wind direction board whose width is longer than a blower outlet, without interfering with a main part outline.

本発明は、特に運転時に前部上下風向板が本体と干渉することを防止できる空気調和装置を提供することを課題とする。 An object of the present invention is to provide an air conditioner that can prevent the front vertical airflow direction plate from interfering with the main body during operation.

本発明においては、上記課題を解決するため、吹出口から吹き出される空気を上下方向に変える上下風向板を備え、上下風向板は、後部上下風向板、及び、後部上下風向板よりも前側に位置する前部上下風向板を有し、前部上下風向板は、アームを介して風向板駆動装置と接続され、前部上下風向板の回転軸の中心は吹出口上面と同一面よりも上方に位置し、吹出口上面は凸部を有し、冷房運転時、吹出口上面と前部上下風向板との間の隙間は、凸部がない場合における吹出口上面と前部上下風向板との間の隙間より狭い。
In the present invention, in order to solve the above-mentioned problem, an up-and-down wind direction plate that changes the air blown from the outlet in the up-and-down direction is provided, and the up-and-down wind direction plate is located on the front side of the rear up-and-down wind direction plate and the rear up-and-down wind direction plate. The front vertical wind direction plate is connected to the wind direction plate driving device via the arm, and the center of the rotation axis of the front vertical wind direction plate is above the same plane as the upper surface of the outlet. The upper surface of the air outlet has a convex portion, and during cooling operation, the gap between the upper surface of the air outlet and the front vertical wind direction plate is the upper surface of the air outlet and the front vertical air direction plate when there is no convex portion. Narrower than the gap between.

本発明によれば、運転時に前部上下風向板が本体と干渉することを防止できる。
According to the present invention, the front vertical wind direction plate can be prevented from interfering with the main body during operation.

本発明に係る空気調和装置の室内機構成,機能および動作について説明する。   The indoor unit configuration, function, and operation of the air conditioner according to the present invention will be described.

はじめに、図1から図6を参照して、この発明の実施例に係る空気調和装置の室内機の構成を具体的に説明する。ここで、この発明に係る空気調和装置の室内機において、図1は運転中の斜視図であり、図2は運転中の要部縦断面図である。図3は運転停止時の斜視図であり、図4は運転停止時の要部縦断面図である。また、図5は図2における吹出口4付近の吹出口拡大図100であり、図6は図4における吹出口4付近の吹出口拡大図101である。   First, with reference to FIGS. 1 to 6, the configuration of the indoor unit of the air conditioner according to the embodiment of the present invention will be described in detail. Here, in the indoor unit of the air conditioner according to the present invention, FIG. 1 is a perspective view during operation, and FIG. 2 is a longitudinal sectional view of a main part during operation. FIG. 3 is a perspective view when the operation is stopped, and FIG. 4 is a longitudinal sectional view of the main part when the operation is stopped. 5 is an enlarged view 100 of the air outlet near the air outlet 4 in FIG. 2, and FIG. 6 is an enlarged view 101 of the air outlet near the air outlet 4 in FIG.

先ず、本実施例に係る空気調和装置の概略構造を説明する。本実施例に係る空気調和装置は、圧縮機,室外熱交換器,室外送風機,四方弁,膨張弁を備え、屋外に設置される図示しない室外機と、図1,図2に示す室内熱交換器5,室内貫流ファン6を備え、室内壁面に取り付けられる室内機とを図示しない冷媒配管を介して接続することで、室内の空調を可能にするものである。   First, the schematic structure of the air conditioning apparatus according to the present embodiment will be described. The air conditioner according to the present embodiment includes a compressor, an outdoor heat exchanger, an outdoor blower, a four-way valve, and an expansion valve, and an outdoor unit (not shown) installed outdoors and the indoor heat exchange shown in FIGS. The room 5 is provided with the indoor cross-flow fan 6 and is connected to an indoor unit attached to the wall surface of the room via a refrigerant pipe (not shown) to enable indoor air conditioning.

図1において室内機は、奥行寸法より高さ寸法が大きく、高さ寸法より横幅寸法が大きい横長の筺体1を備えている。筺体1は、筺体1上面に形成される上部吸込部2と、筺体1の前面上部に形成される前部吸込部3とから取り込んだ空気を筺体1の下面前部に形成される吹出口4から吹出す空気流路が内部に形成されている。そして、図2に示すように室内貫流ファン6が空気流路の中央に、筐体1内の空気流路長手方向と一致した長さで配置されている。さらに、図1に示すように、室内貫流ファン6の前後には、前部ドレン皿7と、後部ドレン皿8が設けられ、この前部ドレン皿7と後部ドレン皿8を跨いで室内貫流ファン6の上部を覆うように室内熱交換器5が配置されている。   In FIG. 1, the indoor unit includes a horizontally long casing 1 having a height dimension larger than the depth dimension and a width dimension larger than the height dimension. The housing 1 has an air outlet 4 formed at the front of the lower surface of the housing 1 with air taken in from an upper suction portion 2 formed on the upper surface of the housing 1 and a front suction portion 3 formed on the front upper portion of the housing 1. The air flow path which blows out from is formed in the inside. As shown in FIG. 2, the indoor cross-flow fan 6 is arranged in the center of the air flow path with a length that matches the longitudinal direction of the air flow path in the housing 1. Further, as shown in FIG. 1, a front drain tray 7 and a rear drain tray 8 are provided before and after the indoor cross-flow fan 6, and the indoor cross-flow fan straddling the front drain tray 7 and the rear drain tray 8. An indoor heat exchanger 5 is arranged so as to cover the upper part of 6.

また、本実施例の室内空気取入口は、常に開放して設けられる上部吸込部2と、可動パネル9が開閉可能に設けられる前部吸込部3とから構成される。図2に示すように、上部吸込部2は、ほぼ水平な上面に設けられ、前部吸込部3は、ほぼ垂直な筺体1前面の上部3/5程度の大きさをもって形成される。そして、筺体1前面の上部に形成される前部吸込部3を、可動パネル9により開閉する構造を備えている。可動パネル9は、板状の部材で形成され、可動パネル9下端部はパネル回転軸10を介して回転可能に取り付けられ、可動パネル9上部は、筺体1内に設けられるパネル駆動機構部11と接続されている。   Moreover, the indoor air intake port of the present embodiment includes an upper suction portion 2 that is always opened and a front suction portion 3 that is provided so that the movable panel 9 can be opened and closed. As shown in FIG. 2, the upper suction portion 2 is provided on a substantially horizontal upper surface, and the front suction portion 3 is formed with a size of about 3/5 of the front surface of the substantially vertical housing 1. And the structure which opens and closes the front suction part 3 formed in the upper part of the front surface of the housing 1 with the movable panel 9 is provided. The movable panel 9 is formed of a plate-like member, and the lower end portion of the movable panel 9 is rotatably attached via a panel rotation shaft 10, and the upper portion of the movable panel 9 is connected to a panel drive mechanism unit 11 provided in the housing 1. It is connected.

本構造によれば、パネル駆動機構部11を動作させることにより、可動パネル9を、パネル回転軸10を中心に揺動させ、図1,図2に示すように前部吸込部3を開放させた状態と、図3,図4に示すように前部吸込部3を閉じた状態とを取らせることができる。   According to this structure, by operating the panel drive mechanism 11, the movable panel 9 is swung around the panel rotation shaft 10, and the front suction part 3 is opened as shown in FIGS. As shown in FIGS. 3 and 4, the front suction portion 3 can be closed.

また、図2に示すように、吹出口4は、室内貫流ファン6により生成される空気流を前方に効率よく吹出せるように、筺体1の長手方向に沿って形成され、室内貫流ファン6と前部ドレン皿7の下方は大きく開放される。   As shown in FIG. 2, the air outlet 4 is formed along the longitudinal direction of the housing 1 so that the air flow generated by the indoor once-through fan 6 can be efficiently blown forward. The lower part of the front drain pan 7 is largely opened.

さらに吹出口4には、前部上下風向板12と後部上下風向板13とからなる板状の風向板が設けられている。前部上下風向板12は、吹出口4から吹出される空気流のガイドの機能(吹出口4から吹出される空気流の上下方向の風向を偏向する)と、可動パネル9のパネル回転軸10近傍を目立たなくする化粧部材の機能を備えている。   Further, the blower outlet 4 is provided with a plate-like wind direction plate including a front vertical wind direction plate 12 and a rear vertical wind direction plate 13. The front vertical wind direction plate 12 functions as a guide for the airflow blown from the blowout port 4 (deflects the vertical wind direction of the airflow blown from the blowout port 4), and the panel rotation shaft 10 of the movable panel 9. It has the function of a decorative member that makes the vicinity inconspicuous.

図3に示すように、この実施例の可動パネル9は、正面を上下に分割するように、正面の上部全体を覆う構造としているため、パネル回転軸10近傍の隙間は、筺体1の横幅一杯まで生じる。そこで本実施例では、前部上下風向板12の横幅を、可動パネル9下部に隣接して形成される筺体面を覆う大きさ、即ち、筺体1の横幅とほぼ同じ大きさに設定している。   As shown in FIG. 3, the movable panel 9 of this embodiment has a structure that covers the entire upper part of the front so that the front is divided into upper and lower parts, so that the gap near the panel rotation shaft 10 is full of the width of the casing 1. To occur. Therefore, in this embodiment, the lateral width of the front vertical wind direction plate 12 is set to a size that covers the housing surface formed adjacent to the lower portion of the movable panel 9, that is, substantially the same as the lateral width of the housing 1. .

さらに、前部上下風向板12の奥行き寸法は後部上下風向板13の奥行き寸法より小さく形成され、前部上下風向板12を閉じた状態で、前部吸込部3と吹出口4との間に形成される筺体面を覆う大きさを備えている。   Further, the depth dimension of the front vertical wind direction plate 12 is formed smaller than the depth dimension of the rear vertical wind direction plate 13, and the front vertical wind direction plate 12 is closed between the front suction part 3 and the outlet 4. It has a size that covers the surface of the body to be formed.

また、前部上下風向板12は、図1に示すように吹出口4の横方向(長手方向)に複数のアーム16により、吹出口4の前方に配置される前部上下風向板回転軸17と接続され、図示しない風向板駆動装置により回転可能に設けられる。   Further, as shown in FIG. 1, the front vertical airflow direction plate 12 has a front vertical airflow direction plate rotating shaft 17 disposed in front of the air outlet 4 by a plurality of arms 16 in the lateral direction (longitudinal direction) of the air outlet 4. And is rotatably provided by a wind direction plate driving device (not shown).

一方、後部上下風向板13は、吹出口4から吹出される空気流のガイドの機能と、閉じた時に吹出口4を隠蔽する機能を備えている。このため、後部上下風向板13の横幅は、吹出口4の前部を覆うことができる大きさに設定している。後部上下風向板13の奥行き寸法は、後部上下風向板13を閉じた状態で前部上下風向板回転軸17付近(前部上下風向板12の後端部)までを覆う大きさを備えている。後部上下風向板13は、吹出口4の横方向に複数のアームで図示しない風向板駆動装置と接続され、吹出口4の後方に配置される後部上下風向板回転軸18を中心に回転可能に設けられる。   On the other hand, the rear vertical wind direction plate 13 has a function of guiding the air flow blown from the blower outlet 4 and a function of concealing the blower outlet 4 when closed. For this reason, the lateral width of the rear vertical wind direction plate 13 is set to a size that can cover the front portion of the outlet 4. The depth dimension of the rear vertical wind direction plate 13 is large enough to cover the vicinity of the front vertical wind direction plate rotating shaft 17 (the rear end of the front vertical wind direction plate 12) with the rear vertical wind direction plate 13 closed. . The rear vertical wind direction plate 13 is connected to a wind direction plate driving device (not shown) by a plurality of arms in the lateral direction of the air outlet 4, and is rotatable around a rear vertical air direction plate rotating shaft 18 disposed behind the air outlet 4. Provided.

ここで、吹出口4の構成について、図5を用いて詳細に説明する。吹出口4の前方に設けられる前部上下風向板12には、前部上下風向板12のアーム16に接続された前部補助風向板15が設置されている。前部補助風向板15は、冷房運転など上向き風向の場合、前部上下風向板12が上向き角度で、前部補助風向板15が床面に対し水平になるよう、暖房運転など下向き風向の場合、前部上下風向板12′が下向き角度で、前部補助風向板15が床面に対しほぼ垂直を為す角度になるよう、前部補助風向板15の前後端部を結んだ前端部側の延長線が前部上下風向板12と交わる角度で設置される。   Here, the structure of the blower outlet 4 is demonstrated in detail using FIG. A front auxiliary wind direction plate 15 connected to an arm 16 of the front vertical wind direction plate 12 is installed on the front vertical wind direction plate 12 provided in front of the air outlet 4. When the front auxiliary wind direction plate 15 is in an upward wind direction such as cooling operation, the front vertical wind direction plate 12 is at an upward angle, and the front auxiliary wind direction plate 15 is in a downward direction such as heating operation so that the front auxiliary wind direction plate 15 is horizontal with respect to the floor surface. The front upper wind direction plate 12 'is at a downward angle and the front auxiliary wind direction plate 15 is at an angle that is substantially perpendicular to the floor surface. The extension line is installed at an angle that intersects the front vertical wind direction plate 12.

また、吹出口4の出口上端角部には、凸部14を設けている。凸部14は頂部が吹出口上面200に対し流路と反対側になるよう形成され、吹出口上面200の流路が滑らかに上方向に拡大する形状になる。また、凸部14は、吹出口4の横幅全体に同じ断面で設けられる。   Further, a convex portion 14 is provided at the outlet upper end corner of the outlet 4. The convex portion 14 is formed such that the top portion is opposite to the flow path with respect to the air outlet upper surface 200, and the flow path of the air outlet upper surface 200 is smoothly expanded upward. Moreover, the convex part 14 is provided in the whole cross-sectional width of the blower outlet 4 with the same cross section.

続いて、前部上下風向板回転軸17の中心位置について、図6を用いて詳細に説明する。図6で、点Cは前部上下風向板回転軸17の中心である。点D1は運転停止角度位置における前部上下風向板12の風上側端であり、吹出口上面200に対し風路と反対側にある。また、点D2は吹出風を下方へ導くための最大角度位置における前部上下風向板12′の風上側端である。さらに、面Yは、吹出口上面200と同一面を、面Zは、本体下面外形を示す。   Next, the center position of the front vertical wind direction plate rotating shaft 17 will be described in detail with reference to FIG. In FIG. 6, the point C is the center of the front vertical wind direction plate rotating shaft 17. The point D1 is the windward end of the front vertical wind direction plate 12 at the operation stop angle position, and is on the side opposite to the wind path with respect to the blower outlet upper surface 200. Point D2 is the windward end of the front vertical wind direction plate 12 'at the maximum angular position for guiding the blown wind downward. Furthermore, the surface Y shows the same surface as the air outlet upper surface 200, and the surface Z shows the main body lower surface outer shape.

ここで、点Cは、D1からCまでの距離L1と、Zと接するまで前部上下風向板12′が回転した点D2とYとの最短距離L2の関係がL1>L2である位置に設けられる。   Here, the point C is provided at a position where the relationship between the distance L1 from D1 to C and the shortest distance L2 between the point D2 and Y where the front vertical wind direction plate 12 'rotates until it contacts Z is L1> L2. It is done.

上述した関係を満たす位置に前部上下風向板回転軸17の中心Cを設けることで、例えば本実施例のように、前部上下風向板12の横幅を筺体1とほぼ同じ大きさにすることができ、意匠性の高い室内機が実現できる。   By providing the center C of the front vertical airflow plate rotating shaft 17 at a position satisfying the above-described relationship, for example, as in the present embodiment, the horizontal width of the front vertical airflow direction plate 12 is made approximately the same size as the housing 1. And an indoor unit with high design can be realized.

本実施例では、室内貫流ファン6や可動パネル9の駆動機構部及び前部上下風向板12,後部上下風向板13の駆動機構部などは、筺体1内に設けられる図示しない制御部によって統括制御され、また、制御部は図示しない遠隔操作装置によって操作指示を受付けることができる。このため筺体1面の片側に、図示しない遠隔操作機との間で操作信号を送受信する信号送受信部が設けられている。   In the present embodiment, the drive mechanisms of the indoor cross-flow fan 6 and the movable panel 9 and the drive mechanisms of the front vertical wind direction plate 12 and the rear vertical wind direction plate 13 are controlled by a control unit (not shown) provided in the housing 1. In addition, the control unit can accept an operation instruction by a remote operation device (not shown). For this reason, a signal transmission / reception unit for transmitting / receiving an operation signal to / from a remote controller (not shown) is provided on one side of the housing 1 surface.

本実施例に係る制御部は、運転状態では、図1,図2に示すように、可動パネル9と前部上下風向板12,後部上下風向板13を開放するように制御し、運転停止状態では、図3,図4に示すように、可動パネル9と前部上下風向板12,後部上下風向板13を閉じて、前部吸込部3と吹出口4を隠蔽するように制御する。   As shown in FIGS. 1 and 2, the control unit according to the present embodiment controls the movable panel 9, the front vertical wind direction plate 12, and the rear vertical wind direction plate 13 to be opened, as shown in FIGS. Then, as shown in FIGS. 3 and 4, the movable panel 9, the front up / down wind direction plate 12, and the rear up / down wind direction plate 13 are closed, and the front suction unit 3 and the outlet 4 are concealed.

続いて、本実施例における各運転状態における動作の詳細について説明する。室内機が運転状態のとき、室内貫流ファン6を動作させることにより、上部吸込部2と大きく開放した前部吸込部3から室内空気を取り込み、室内熱交換器5により運転モードに応じた温湿度に熱交換を行い、熱交換された室内空気を運転モードに対応して所定角度に開放した前部上下風向板12,後部上下風向板13に従って吹き出すことができる。   Then, the detail of operation | movement in each driving | running state in a present Example is demonstrated. When the indoor unit is in an operating state, the indoor cross-flow fan 6 is operated to take in indoor air from the upper suction portion 2 and the front suction portion 3 that is largely open, and the indoor heat exchanger 5 performs temperature and humidity according to the operation mode. Then, the heat exchanged room air can be blown out according to the front vertical wind direction plate 13 and the rear vertical wind direction plate 13 which are opened at a predetermined angle corresponding to the operation mode.

冷房運転時の前部上下風向板12,後部上下風向板13の状態について図7を用いて説明する。図7は図2における吹出口4付近の吹出口拡大図100で、前部上下風向板12,後部上下風向板13は冷房運転時の位置に回転した図である。   The state of the front vertical wind direction plate 12 and the rear vertical wind direction plate 13 during the cooling operation will be described with reference to FIG. FIG. 7 is an enlarged view 100 of the air outlet in the vicinity of the air outlet 4 in FIG. 2, in which the front vertical air direction plate 12 and the rear vertical air direction plate 13 are rotated to the position during the cooling operation.

空気調和装置を冷房運転する時には図7のように前部上下風向板12は水平な向きに、後部上下風向板13は吹出口上面200と略平行な向きにして使用される。吹出口4より吐出された冷風は、上流側の室内熱交換器5により冷却減湿されているため周囲空気よりも温度が低く密度が大きく、下方へ流出するが、後部上下風向板13により上方へ持ち上げられる。一方、吹出口上面200では前部上下風向板12およびそのアーム16に設けられた前部補助風向板15により、前方へ導かれ、吹出口4出口の拡大流路による流れの散逸を防ぎより遠方に冷風を導いている。   When the air conditioner is in cooling operation, the front vertical airflow direction plate 12 is used in a horizontal direction and the rear vertical airflow direction plate 13 is used in a direction substantially parallel to the air outlet upper surface 200 as shown in FIG. The cold air discharged from the blower outlet 4 is cooled and dehumidified by the upstream indoor heat exchanger 5, and therefore has a lower temperature and a higher density than the surrounding air, and flows downward. To be lifted. On the other hand, the air outlet upper surface 200 is guided forward by the front upper airflow direction plate 12 and the front auxiliary airflow direction plate 15 provided on the arm 16 to prevent the flow from being dissipated by the enlarged flow path at the air outlet 4 outlet. To guide the cold air.

ここで、吹出口4出口端部に設けられた凸部14と前部補助風向板15,前部上下風向板12周辺の流れに対しての本実施例を用いた場合の効果について図8(a),(b)を用いて説明する。図8(a)は吹出口4出口端部に凸部14がない場合の吹出口4周辺を示し、(b)は本実施例の吹出口4出口端部に凸部14を設けた場合を示す。図8(a)において、吹出口4出口端と、前部補助風向板15の後端の間に風向板を稼動させるため隙間がある。吹出口4を流れる冷風(吹出し空気流れ(冷風)63)がこの隙間を通過する際、流れの一部が流出し、吹出口4出口端で流速が減少し、風路と反対側の吹出口4出口端付近に周囲空気の流れ61と混合しやすい領域Xができる。冷却減湿された冷風(吹出し空気流れ(冷風)63)に対して周囲空気の流れ61は高湿であり、これらが混合することで、吹出口4出口端の表面で結露が生じる。   Here, the effect of using this embodiment with respect to the flow around the convex portion 14 provided at the outlet end of the outlet 4, the front auxiliary wind direction plate 15, and the front vertical wind direction plate 12 is shown in FIG. This will be described with reference to a) and (b). FIG. 8A shows the periphery of the outlet 4 when the outlet 4 has no convex portion 14 at the outlet end, and FIG. 8B shows the case where the convex portion 14 is provided at the outlet 4 outlet end of this embodiment. Show. In FIG. 8A, there is a gap between the outlet end of the outlet 4 and the rear end of the front auxiliary wind direction plate 15 for operating the wind direction plate. When the cold air flowing through the outlet 4 (blow air flow (cold air) 63) passes through this gap, part of the flow flows out, the flow velocity decreases at the outlet end of the outlet 4, and the outlet on the opposite side of the air passage A region X that is easy to mix with the ambient air flow 61 is formed near the end of the four outlets. The ambient air flow 61 is highly humid than the cooled and dehumidified cold air (blow air flow (cool air) 63), and when these are mixed, dew condensation occurs on the surface of the outlet 4 outlet end.

一方、図8(b)では、凸部14により上述した隙間が狭くなるため、流出する流れが減少し、さらに、凸部により流路形状が滑らかになるため、流れの一部が流出しても流速が減少せずに周囲空気の流れ61と混合されにくくなり、領域Xが小さくなる。その結果、吹出口4出口端部表面の結露を防止できる。   On the other hand, in FIG. 8B, the gap described above is narrowed by the convex portion 14, so that the flow that flows out decreases, and further, the flow path shape is smoothed by the convex portion, so that part of the flow flows out. However, the flow velocity does not decrease, and it becomes difficult to mix with the flow 61 of the surrounding air, and the region X becomes small. As a result, condensation on the surface of the outlet end portion of the outlet 4 can be prevented.

さらに、前部補助風向板15は、床面に対し水平で、前部上下風向板12に対し、前後端部を結んだ前端部側の延長線が前部上下風向板12と交わる角度で設けられているため、冷風はすぐに下方へ向かわずに部屋全体にいきわたり、室内を快適な温湿度に保つ。   Further, the front auxiliary wind direction plate 15 is horizontal with respect to the floor, and is provided at an angle at which the extension line on the front end side connecting the front and rear ends intersects the front vertical wind direction plate 12 with respect to the front vertical wind direction plate 12. As a result, the cold wind does not immediately go downward, but it travels throughout the room and keeps the room at a comfortable temperature and humidity.

次に、上向き風向時の前部上下風向板12,後部上下風向板13の状態について図9を用いて説明する。図9は図2における吹出口4付近の吹出口拡大図100で、上前部上下風向板12,後部上下風向板13は極弱い冷房または暖房運転の位置に回転している。   Next, the state of the front up / down wind direction plate 12 and the rear up / down wind direction plate 13 in the upward wind direction will be described with reference to FIG. FIG. 9 is an enlarged view 100 of the air outlet in the vicinity of the air outlet 4 in FIG. 2. The upper front up / down wind direction plate 12 and the rear up / down air direction plate 13 are rotated to a position of extremely weak cooling or heating operation.

本運転時では図9のように前側上下風向板12をやや上向きにし、後部上下風向板13をほぼ閉じる向きにする。これにより、吹出し空気の一部(吹出し空気流れ(微弱な冷風または温風)71)が極弱い風(吹出し空気流れ(微弱な冷風または温風)72)となって上方にふんわりと室内に拡散し、微弱な冷房または暖房を行う。さらに、吹出した風をすぐさま、上部吸込部2,前部吸込部3から吸込ませるショートサーキット運転を行うことで、熱交換器の乾燥運転や空気調和装置内部の脱臭運転などの空気調和装置のメンテナンス動作を行わせることも可能となる。   During the actual operation, as shown in FIG. 9, the front vertical wind direction plate 12 is slightly upward, and the rear vertical wind direction plate 13 is substantially closed. As a result, a part of the blown air (the blown air flow (weak cold air or warm air) 71) becomes extremely weak wind (the blown air flow (weak cold wind or hot air) 72) and diffuses softly upward in the room. And perform weak cooling or heating. Furthermore, maintenance of the air conditioner such as drying operation of the heat exchanger and deodorizing operation inside the air conditioner is performed by performing a short circuit operation in which the blown wind is immediately sucked from the upper suction unit 2 and the front suction unit 3. It is also possible to perform the operation.

次に、暖房運転時の前部上下風向板12,後部上下風向板13の状態について図10を用いて説明する。図10は図2における吹出口4付近の吹出口拡大図100であるが、前部上下風向板12,後部上下風向板13は暖房運転の位置に回転している。   Next, the state of the front vertical wind direction plate 12 and the rear vertical wind direction plate 13 during the heating operation will be described with reference to FIG. FIG. 10 is an enlarged view 100 of the air outlet near the air outlet 4 in FIG. 2, but the front vertical air direction plate 12 and the rear vertical air direction plate 13 are rotated to the heating operation position.

空気調和装置を暖房運転する時には、前部上下風向板12,後部上下風向板13は図10のようにそれぞれほぼ垂直に近い向きにして使用される。吹出口4から吐出される温風(吹出し空気流れ(温風)81)は、周囲空気より密度が小さいために上方へ浮き上がろうとする。しかし、前部上下風向板12,後部上下風向板13により下方(吹出し空気流れ(温風)82)へ導かれる。このとき前部上下風向板12および、そのアーム16に設けられた前部補助風向板15は、温風(吹出し空気流れ(温風)81)を押さえ込み、下方(吹出し空気流れ(温風)82)へと導いている。この結果、温風は、吹出口4から吐出してすぐに上方へ向かわずに、床面近くまで到達して、足もと近くを暖め、室内を快適な環境にする。   When the air conditioner is operated for heating, the front upper and lower wind direction plates 12 and the rear upper and lower wind direction plates 13 are used in directions almost perpendicular to each other as shown in FIG. The warm air (blow air flow (warm air) 81) discharged from the outlet 4 has a lower density than the ambient air, and therefore tends to float upward. However, it is guided downward (blowing air flow (warm air) 82) by the front vertical wind direction plate 12 and the rear vertical wind direction plate 13. At this time, the front vertical wind direction plate 12 and the front auxiliary wind direction plate 15 provided on the arm 16 hold down the warm air (blowing air flow (warm air) 81) and move downward (blowing air flow (warm air) 82. ). As a result, the warm air is discharged from the air outlet 4 and does not immediately go upward, but reaches near the floor, warms the feet and makes the room a comfortable environment.

以上、各運転モードでの前部上下風向板12,後部上下風向板13の動作について述べたが、上述した動作のほかにユーザーの希望に応じて、適宜、前部上下風向板12,後部上下風向板13の方向をリモコンで変更することもできる。   The operation of the front vertical airflow direction plate 12 and the rear vertical airflow direction plate 13 in each operation mode has been described above. In addition to the above-described operation, the front vertical airflow direction plate 12 and the rear vertical airflow direction plate are appropriately selected according to the user's request. The direction of the wind direction plate 13 can also be changed with a remote controller.
