Description

本発明は、空気調和機の室内機に関する。 The present invention relates to an indoor unit of an air conditioner.

地球の温暖化に伴い、近年は今まで経験したことがない激しい気象現象が発生している。特に、３０℃以上の暑い真夏日の期間が長く続くことから、初夏（６月初め）から秋口（１０月終わり）にかけて空気調和機（所謂クーラー又はエアコン）の使用が欠かせなくなって来ている。ところが、空気調和機の室内機から吹き出される冷風や温風の流速が大きい気流が人体に当たることで、不快を感じる人が増えている。この不快感を抑制するため、人体の位置を避けて、室内機内の熱交換器周囲を流れた気流を流す機構を有する空気調和機が多数提案されている(例えば、特許文献１、特許文献２)。 With global warming, severe meteorological phenomena that have never been experienced have occurred in recent years. In particular, since the period of hot midsummer days of 30 ° C or higher continues for a long time, it is becoming indispensable to use an air conditioner (so-called cooler or air conditioner) from early summer (early June) to early autumn (end of October). .. However, an increasing number of people feel uncomfortable when the airflow of cold air or hot air blown out from the indoor unit of an air conditioner hits the human body. In order to suppress this discomfort, many air conditioners having a mechanism for flowing an air flow flowing around the heat exchanger in the indoor unit while avoiding the position of the human body have been proposed (for example, Patent Document 1 and Patent Document 2). ).

特許第３３９２６４４号公報Japanese Patent No. 3392644 特許第６４２１６６７号公報Japanese Patent No. 6421667

人体の位置を避けて気流を流す場合、熱交換器周囲を流れて温度を調整された気流が人体周囲に届きにくくなるため、人体周囲を所定の設定温度に到達させるのに長時間を要することが課題であった。また、人が複数いた場合には、各人体を避けて気流を流すことが困難であった。さらに、人体に気流が当たりにくくする場合、気流のにおいに気づきにくく、フィルターの汚れに気づきにくくなるという課題もあった。 When the airflow avoids the position of the human body, it takes a long time to reach the predetermined set temperature around the human body because the airflow whose temperature has been adjusted by flowing around the heat exchanger is difficult to reach around the human body. Was an issue. In addition, when there were multiple people, it was difficult to avoid each human body and let the air flow flow. Further, when it is difficult for the airflow to hit the human body, there is a problem that it is difficult to notice the odor of the airflow and it is difficult to notice the dirt on the filter.

本発明は、上記した課題を解決しようとするものであって、吹出される気流により人が不快に感じることを抑制できる空気調和機の室内機を提供することを目的とする。 An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an indoor unit of an air conditioner capable of suppressing a person from feeling uncomfortable due to an air flow blown out.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、実施形態に係る室内機の概略の断面図を示している。実際の空気調和機は、室内機に室外機が接続されて動作するが、ここでは室内機のみを示す。室内機１０は、筐体２０、熱交換器３０、フィルター４０、フィルター掃除機構５０、横流ファン６０、上ルーバー７０、下ルーバー８０、板状構造体９０等から構成されている。なお、上ルーバー７０および下ルーバー８０が本発明における風向板に相当する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic cross-sectional view of the indoor unit according to the embodiment. An actual air conditioner operates by connecting an outdoor unit to an indoor unit, but only the indoor unit is shown here. The indoor unit 10 is composed of a housing 20, a heat exchanger 30, a filter 40, a filter cleaning mechanism 50, a cross flow fan 60, an upper louver 70, a lower louver 80, a plate-shaped structure 90, and the like. The upper louver 70 and the lower louver 80 correspond to the wind direction plate in the present invention.

室内機１０は、上下方向の寸法に対して左右方向の寸法が長い横長状をなす筐体２０の内部に、熱交換器３０、フィルター４０、フィルター掃除機構５０、横流ファン６０等を備えて構成されている。また、筐体２０の上部手前には、室内の空気を筐体内に吸い込むための空気吸込み口２０ａが設けられている。また、筐体２０の下部には、筐体内に吸い込まれた空気が熱交換機３０を介して温度調整され、横流ファン６０により室内に吹き出すための空気吹出し口１００が形成されている。空気吹出し口１００は、上ルーバー７０、下ルーバー８０により開閉可能に構成されている。これにより、筐体２０の傾斜面と上ルーバー７０との間には上側流路が形成され、上ルーバー７０と下ルーバー８０の間には、下側流路が形成される。そして、板状構造体９０は、上側流路の風を拡散させて、後述するような「ジェット気流」を生成するために設けられる、例えば合成樹脂から成る板状部材である。この筐体２０は、図示しない室内の壁面に取り付けられる。なお、図１では、右側が壁面側であり、左側が室内側である。 The indoor unit 10 includes a heat exchanger 30, a filter 40, a filter cleaning mechanism 50, a cross flow fan 60, and the like inside a horizontally long housing 20 having a long horizontal dimension with respect to the vertical dimension. Has been done. Further, in front of the upper part of the housing 20, an air suction port 20a for sucking indoor air into the housing is provided. Further, in the lower part of the housing 20, an air outlet 100 is formed in which the temperature of the air sucked into the housing is adjusted via the heat exchanger 30 and the air is blown into the room by the cross flow fan 60. The air outlet 100 is configured to be openable and closable by the upper louver 70 and the lower louver 80. As a result, an upper flow path is formed between the inclined surface of the housing 20 and the upper louver 70, and a lower flow path is formed between the upper louver 70 and the lower louver 80. The plate-shaped structure 90 is a plate-shaped member made of, for example, a synthetic resin, which is provided to diffuse the wind in the upper flow path to generate a "jet stream" as described later. The housing 20 is attached to a wall surface in a room (not shown). In FIG. 1, the right side is the wall surface side and the left side is the indoor side.

筐体２０の内部には、空気吸込み口２０ａから空気吹出し口１００にわたって通風路が形成されている。この通風路に、熱交換器３０及び横流ファン６０が配置されている。横流ファン６０は、図１の長手方向、つまり左右方向に沿う回転軸６０ａを中心として回転可能に設けられている。室内機１０は、通風路内において横流ファン６０を回転させることにより、室内の空気を空気吸込み口２０ａから吸い込み、空気吹出し口１００から吹き出すように送風する。空気吸込み口２０ａから吸い込まれた空気は、通風路内を流れる過程で熱交換器３０によって熱交換され、周知の暖房運転時では温風として、周知の冷房運転時では冷風として空気吹出し口１００から室内に吹き出される。 Inside the housing 20, a ventilation path is formed from the air suction port 20a to the air outlet 100. A heat exchanger 30 and a cross flow fan 60 are arranged in this ventilation path. The cross-flow fan 60 is rotatably provided about a rotation shaft 60a along the longitudinal direction of FIG. 1, that is, the left-right direction. The indoor unit 10 sucks the air in the room from the air suction port 20a and blows it out from the air outlet 100 by rotating the cross flow fan 60 in the ventilation path. The air sucked from the air suction port 20a is heat-exchanged by the heat exchanger 30 in the process of flowing in the ventilation passage, and is treated as hot air during the well-known heating operation and as cold air during the well-known cooling operation from the air outlet 100. It is blown into the room.

上ルーバー７０と下ルーバー８０は、空気吹出し口１００に開閉可能に設けられる。上ルーバー７０は上側流路を開閉し、下ルーバー８０は下側流路を開閉する。空気吹出し口１００から吹出される風を拡散させる板状構造体９０は、上ルーバー７０の近くの筐体２０内に収納可能に取り付けられる。上ルーバー７０、下ルーバー８０、および板状構造体９０は、回動軸を有し、後述するモータにより開閉制御される。フィルター掃除機構５０は、板状構造体９０および熱交換器３０よりも前方であって、筐体２０の内側に配置され、利用者のボタン操作に応じて、フィルター４０に付着したゴミ等の付着物をクリーニングする。即ち、筐体２０に流入する空気は、フィルター４０を通ることで、空気中のホコリやカビ胞子などの微粒子がフィルター上に捕捉される。このフィルター４０をフィルター掃除機構５０で定期的に掃除することで、人がホコリやカビ胞子の増大に伴う気流のにおいに気づかなかったとしても、フィルター４０を清潔に保つことができる。 The upper louver 70 and the lower louver 80 are provided at the air outlet 100 so as to be openable and closable. The upper louver 70 opens and closes the upper flow path, and the lower louver 80 opens and closes the lower flow path. The plate-shaped structure 90 that diffuses the wind blown from the air outlet 100 is storably mounted in the housing 20 near the upper louver 70. The upper louver 70, the lower louver 80, and the plate-shaped structure 90 have a rotating shaft and are controlled to open and close by a motor described later. The filter cleaning mechanism 50 is located in front of the plate-shaped structure 90 and the heat exchanger 30 and is arranged inside the housing 20, and is attached with dust or the like adhering to the filter 40 in response to a user's button operation. Clean the kimono. That is, the air flowing into the housing 20 passes through the filter 40, so that fine particles such as dust and mold spores in the air are captured on the filter. By periodically cleaning the filter 40 with the filter cleaning mechanism 50, the filter 40 can be kept clean even if a person does not notice the odor of the air flow accompanying the increase of dust and mold spores.

図２は、室内機１０の前面パネルを開いた状態を示す図である。図１で示した構成以外に、空気吹出し口１００の上ルーバーの上側には、左右風向ルーバー１１０が設けられている。また、自動運転ボタン１２０が空清ユニット１３０の中央付近に設けられている。また、空清ユニット１３０の下側にはフィルターをクリーニングした際の付着物を収納するダストボックス１４０が設けられている。図２では、板状構造体９０は、筐体の奥側に収納された状態（閉じられた状態、換言すると上側流路を塞いでいない状態）を示している。 FIG. 2 is a diagram showing a state in which the front panel of the indoor unit 10 is opened. In addition to the configuration shown in FIG. 1, left and right wind direction louvers 110 are provided above the upper louvers of the air outlet 100. Further, an automatic operation button 120 is provided near the center of the air cleaning unit 130. Further, a dust box 140 for storing deposits when the filter is cleaned is provided under the air cleaning unit 130. FIG. 2 shows a state in which the plate-shaped structure 90 is housed in the back side of the housing (closed state, in other words, a state in which the upper flow path is not blocked).

図３は、実施形態に係る板状構造体９０の詳細な構成を示す図である。板状構造体９０は、小さな貫通孔がたくさん空いた板状のパーツである。図３（ａ）に示すように、板状構造体９０は、胴体部９０ａと取り付け側部９０ｂとで構成されている。胴体部９０ａの長手方向は、図２の空気吹出し口１００の横方向の長さとほぼ同じ長さ（例えば、約６７０ｍｍ程度）を有し、短手方向は空気吹出し口１００の上側流路の縦方向の最大開口幅よりも短い長さ（例えば、約２５ｍｍ程度）を有している。また胴体部９０ａの厚さは、十分な強度を備えるように所定の厚さ（例えば、約４．５ｍｍ）を有している。取り付け側部９０ｂは、板状構造体９０の長手方向の取付側であり、胴体部９０ａより少し太い幅を有している。取り付け側部９０ｂの端部（例えば、右側）には、モータの駆動軸が挿入される孔が形成されている。 FIG. 3 is a diagram showing a detailed configuration of the plate-shaped structure 90 according to the embodiment. The plate-shaped structure 90 is a plate-shaped part having many small through holes. As shown in FIG. 3A, the plate-shaped structure 90 is composed of a body portion 90a and a mounting side portion 90b. The longitudinal direction of the body portion 90a has substantially the same length as the lateral length of the air outlet 100 of FIG. 2 (for example, about 670 mm), and the lateral direction is the vertical direction of the upper flow path of the air outlet 100. It has a length shorter than the maximum opening width in the direction (for example, about 25 mm). Further, the thickness of the body portion 90a has a predetermined thickness (for example, about 4.5 mm) so as to have sufficient strength. The mounting side portion 90b is the mounting side in the longitudinal direction of the plate-shaped structure 90, and has a width slightly thicker than that of the body portion 90a. A hole into which the drive shaft of the motor is inserted is formed at the end (for example, the right side) of the mounting side portion 90b.

図３（ｂ）に示すように、板状構造体９０の胴体９０ａには、ジェット気流を吹出すことが可能なように多数の貫通孔９０ｃが設けられている。実施形態では、長手方向に３列の貫通孔９０ｃが千鳥状に配列（整列）されて設けられている。この多数の貫通孔９０ｃにより板状構造体９０を通過する気流を、細かく分散させることができる。すなわち、板状構造体９０で空気吹出し口１００の上側流路を塞いだとしても、細かなジェット気流の吹出しが可能となる。また、図３（ｃ）に示すように、各貫通孔９０ｃの孔は、表側および裏側の外側の孔径９０ｅが中央（内側）の孔径９０ｄより大きい孔となっている。例えば、表裏側の孔径は３〜５ｍｍに形成され、中央側の孔径は表裏側の孔径の５０％〜９０％程度の大きさに形成されている。言い換えると、胴体９０ａの表側および裏側は円錐形状の貫通孔９０ｃが形成されている。このように、気流の入口側と出口側（吹出し側）の孔径９０ｅを中央（内側）の孔径９０ｄより大きくすることで、空気吹出し口１００から吹出す気流をより拡散させることができる。なお、貫通孔９０ｃの形状は、丸孔のほか、角孔やスリット状の孔でも構わない。また、貫通孔９０ｃの配列は、３列に限られず、さらに千鳥状の配列にも限られない。 As shown in FIG. 3B, the body 90a of the plate-shaped structure 90 is provided with a large number of through holes 90c so that a jet stream can be blown out. In the embodiment, three rows of through holes 90c are arranged (aligned) in a staggered manner in the longitudinal direction. The airflow passing through the plate-like structure 90 can be finely dispersed by the large number of through holes 90c. That is, even if the upper flow path of the air outlet 100 is blocked by the plate-shaped structure 90, a fine jet stream can be blown out. Further, as shown in FIG. 3C, the holes of each through hole 90c have a hole diameter 90e on the outside of the front side and the back side larger than the hole diameter 90d in the center (inside). For example, the hole diameter on the front and back sides is formed to be 3 to 5 mm, and the hole diameter on the center side is formed to be about 50% to 90% of the hole diameter on the front and back sides. In other words, conical through holes 90c are formed on the front side and the back side of the body 90a. In this way, by making the hole diameters 90e on the inlet side and the outlet side (blowout side) of the airflow larger than the hole diameter 90d in the center (inside), the airflow blown out from the air outlet 100 can be further diffused. The shape of the through hole 90c may be a square hole or a slit-shaped hole in addition to the round hole. Further, the arrangement of the through holes 90c is not limited to the three rows, and is not limited to the staggered arrangement.

図４は、実施形態に係る板状構造体９０の取り付け形状を示す図である。図４（ａ）は、上ルーバー７０、下ルーバー８０、および板状構造体９０を開けた状態の正面図である。図４（ｂ）は、上ルーバー７０、下ルーバー８０、および板状構造体９０を開いた状態（換言すると上側流路を塞いだ状態）の横側から見た図である。図４から明らかなように、板状構造体９０が開いた状態では、空気吹出し口１００の上側流路を板状構造体９０によって塞がれ、多数の貫通孔から細かなジェット気流が吹出される使用状態が形成される。 FIG. 4 is a diagram showing a mounting shape of the plate-shaped structure 90 according to the embodiment. FIG. 4A is a front view of the upper louver 70, the lower louver 80, and the plate-shaped structure 90 in an open state. FIG. 4B is a side view of the upper louver 70, the lower louver 80, and the plate-shaped structure 90 in an open state (in other words, a state in which the upper flow path is closed). As is clear from FIG. 4, when the plate-shaped structure 90 is open, the upper flow path of the air outlet 100 is blocked by the plate-shaped structure 90, and a fine jet stream is blown out from a large number of through holes. The state of use is formed.

図５は、実施形態に係る板状構造体９０によるジェット気流の吹出し原理を示す図である。板状構造体９０が作動すると、図５（ｂ）のように、空気吹出し口１００の上側流路を塞ぐ形になり、貫通孔９０ｃを通して出る風がジェット状の気流に変化する。即ち、図５（ａ）に示すように、横流ファン６０によって吹出された気流は、上ルーバー７０から板状構造体９０に向けて吹出されると、多数の小さな貫通孔９０ｃを通過することで、細かな「ジェット気流」が生成される。そして、多数の小さな貫通孔９０ｃを通過することで、気流の流速は早くなる。その結果、周囲の空気を巻き込む性質が発揮されて、ジェット内の空気をかき混ぜる性質（作用）が発生する。一方、下ルーバー８０側には板状構造体９０が設けられていないので、通常の風（冷風又は温風）が吹出される。 FIG. 5 is a diagram showing a jet stream blowing principle by the plate-shaped structure 90 according to the embodiment. When the plate-shaped structure 90 operates, as shown in FIG. 5B, the upper flow path of the air outlet 100 is closed, and the wind emitted through the through hole 90c changes to a jet-shaped airflow. That is, as shown in FIG. 5A, when the airflow blown out by the cross current fan 60 is blown out from the upper louver 70 toward the plate-shaped structure 90, it passes through a large number of small through holes 90c. , A fine "jet stream" is generated. Then, by passing through a large number of small through holes 90c, the flow velocity of the air flow becomes high. As a result, the property of entraining the surrounding air is exhibited, and the property (action) of stirring the air in the jet is generated. On the other hand, since the plate-like structure 90 is not provided on the lower louver 80 side, normal air (cold air or hot air) is blown out.

その結果、図５（ｂ）に示すように、ジェット気流が下ルーバー８０から吹出される下側の気流を引き込み、かき混ぜ作用によって風の固まりを砕くことで、人が体感しにくい風に変化することが分かった。その砕かれた柔らかい風が人体に注がれることになるので、ユーザ（利用者）は快適な空調環境を得ることができる。 As a result, as shown in FIG. 5B, the jet stream draws in the lower airflow blown out from the lower louver 80 and breaks the wind mass by the stirring action, so that the wind changes to a wind that is difficult for humans to experience. It turned out. Since the crushed soft wind is blown into the human body, the user (user) can obtain a comfortable air-conditioned environment.

図６は、板状構造体９０による効果を評価したもので、室内機を動作（冷房運転）させて１分後の温度分布を示している。図６（ａ）は、板状構造体９０が無い場合の温度分布を示し、右側は板状構造体９０を設けた場合の温度分布を示している。図６（ｂ）の板状構造体９０を設けた場合の温度分布では、図６（ａ）の温度分布に比べ、低温部分（白い部分）が上下に広がっていることが分かる。すなわち、図６（ａ）では、室内機から所定距離の位置において、局所的に冷風があたり、部分的に低温になり易い一方、図６（ｂ）では、広範囲に冷風があたり、部分的に低温になり過ぎることを抑制できると言える。これにより、人が冷えすぎて不快に感じることを抑制しつつ、温度を所定の設定温度に到達させ易くすることができる。 FIG. 6 is an evaluation of the effect of the plate-shaped structure 90, and shows the temperature distribution 1 minute after the indoor unit is operated (cooling operation). FIG. 6A shows the temperature distribution when the plate-shaped structure 90 is not provided, and the right side shows the temperature distribution when the plate-shaped structure 90 is provided. In the temperature distribution when the plate-shaped structure 90 of FIG. 6 (b) is provided, it can be seen that the low temperature portion (white portion) spreads vertically as compared with the temperature distribution of FIG. 6 (a). That is, in FIG. 6 (a), cold air is locally applied at a predetermined distance from the indoor unit and the temperature tends to be partially low, while in FIG. 6 (b), cold air is applied over a wide area and partially. It can be said that it is possible to prevent the temperature from becoming too low. As a result, it is possible to easily bring the temperature to a predetermined set temperature while suppressing the person from feeling uncomfortable due to being too cold.

図７は、実施形態に係る室内機１０の動作を制御する制御回路の構成を示すブロック図である。制御回路２００は、制御部（室内機１０を制御する機能（アプリケーション）を組み込んだマイクロプロセッサで構成される）２１０によって装置全体の動作が制御される。制御部２１０は、上下風向板モータ駆動回路２２０、板状構造体モータ駆動回路２３０、ファンモータ駆動回路２４０、タイマー２５０、リモコン装置２７０の受信部２６０等と接続されており、これらの装置を制御する。なお、図７には実施形態に関係しない他の構成要素については、省略している。 FIG. 7 is a block diagram showing a configuration of a control circuit that controls the operation of the indoor unit 10 according to the embodiment. In the control circuit 200, the operation of the entire device is controlled by a control unit (consisting of a microprocessor incorporating a function (application) for controlling the indoor unit 10) 210.

次に、図１乃至図１１を参照して、実施形態に係る室内機１０の動作を説明する。
図８に示すように、動作開始前の初期位置では、上ルーバー７０、下ルーバー８０、および板状構造体９０は、共に閉じられた状態で位置する。なお、板状構造体９０が閉じられた状態では、筐体内の収納部９０ｆに収納されて、上側流路の気流の流れを妨げることがないように位置決めされている。つまり、板状構造体９０は、筐体２０の上ルーバー７０の上面に形成されている収納部９０ｆに、板状構造体９０と上ルーバー７０の羽部とが対峙した状態で収められている。 Next, the operation of the indoor unit 10 according to the embodiment will be described with reference to FIGS. 1 to 11.
As shown in FIG. 8, in the initial position before the start of operation, the upper louver 70, the lower louver 80, and the plate-like structure 90 are all positioned in a closed state. When the plate-shaped structure 90 is closed, it is housed in the storage portion 90f in the housing and is positioned so as not to obstruct the flow of the air flow in the upper flow path. That is, the plate-shaped structure 90 is housed in the storage portion 90f formed on the upper surface of the upper louver 70 of the housing 20 in a state where the plate-shaped structure 90 and the vanes of the upper louver 70 face each other. ..

そして、リモコン装置２７０から電源ＯＮの赤外線信号を室外機１０の受信部２６０に向けて送信すると、室内機１０の電源が入り、動作が開始する。まず、制御部２１０は、上下風向板モータ駆動回路２２０を介してモータＭ１，Ｍ２を駆動して、図９に示すように、上ルーバー７０と下ルーバー８０を所定の開位置まで開けて、空気吹出し口１００を形成する。このとき、板状構造体９０は、まだ閉じられた状態にある。上ルーバー７０と下ルーバー８０を開位置まで開き終えたタイミングで、制御部２１０は、ファンモータ駆動回路２４０を介して横流ファン６０を回転駆動する。 Then, when the infrared signal of the power ON is transmitted from the remote controller 270 to the receiving unit 260 of the outdoor unit 10, the power of the indoor unit 10 is turned on and the operation is started. First, the control unit 210 drives the motors M1 and M2 via the vertical wind direction plate motor drive circuit 220, opens the upper louver 70 and the lower louver 80 to predetermined open positions, and opens the air to a predetermined open position, as shown in FIG. The outlet 100 is formed. At this time, the plate-shaped structure 90 is still in a closed state. At the timing when the upper louver 70 and the lower louver 80 have been opened to the open position, the control unit 210 rotationally drives the cross flow fan 60 via the fan motor drive circuit 240.

横流ファン６０の回転駆動により、筐体２０の空気吸込み口２０ａおよびフィルター４０を介して筐体外部から空気が筐体内部に流入し、熱交換器３０の周囲を流れる。熱交換器３０は、内部を流れる冷媒により加熱もしくは冷却されているため、熱交換器３０の周囲を流れる空気も加熱もしくは冷却される。この加熱もしくは冷却された空気は、筐体２０および上ルーバー７０と下ルーバー８０により区切られた２つの流路を通って、筐体の外の任意の場所に向かって気流として流れる。従って、図９に示した動作状態は、一般的な室内機１０の使用形態（第１の動作モード）である。図９に示した動作状態において、制御部２１０は、リモコン装置２７０の操作に応じて上ルーバー７０および下ルーバー８０の角度を任意に設定できる。 By the rotational drive of the cross flow fan 60, air flows into the housing from the outside of the housing through the air suction port 20a of the housing 20 and the filter 40, and flows around the heat exchanger 30. Since the heat exchanger 30 is heated or cooled by the refrigerant flowing inside, the air flowing around the heat exchanger 30 is also heated or cooled. The heated or cooled air flows as an air flow toward an arbitrary place outside the housing through two flow paths separated by the housing 20, the upper louver 70 and the lower louver 80. Therefore, the operating state shown in FIG. 9 is a general usage mode (first operating mode) of the indoor unit 10. In the operating state shown in FIG. 9, the control unit 210 can arbitrarily set the angles of the upper louver 70 and the lower louver 80 according to the operation of the remote controller device 270.

図９からの初期動作の続きとして、制御部２１０は、板状構造体モータ駆動回路２３０を介してモータＭ３を駆動する。すると、図１０に示すように、板状構造体９０を所定の開位置（ほぼ垂直位置）まで開ける。この時、板状構造体９０と上ルーバー７０との間には隙間３００が生じている。次に、制御部２１０は、上下風向板モータ駆動回路２２０を介してモータＭ１を駆動して、図１１に示すように、上ルーバー７０を上方に向けて少し回動移動させて（持ち上げて）、板状構造体９０と上ルーバー７０との間の隙間３００が小さくなる位置に位置決めする。これにより、図５に示したような「ジェット気流」が発生できる状態に設定することができる。なお、板状構造体９０と上ルーバー７０との間の隙間３００は、全部塞ぐものであっても良い。すなわち、上側流路を塞いだ状態において、板状構造体９０と上ルーバー７０との間の隙間３００は、吹き出す気流の減速の程度、又は流量に応じて適宜に設定できる。従って、図１１に示した動作状態は、快適な空調環境を提供する使用形態（第２の動作モード）である。ここでは、初期動作の続きとして板状構造体９０を開けるとしたが、例えばリモコン装置２７０からの操作に基づいて開けても良い。また、図１１に状態に設定してから、横流ファン６０を駆動するようにしても良い。 As a continuation of the initial operation from FIG. 9, the control unit 210 drives the motor M3 via the plate-shaped structure motor drive circuit 230. Then, as shown in FIG. 10, the plate-shaped structure 90 is opened to a predetermined open position (almost vertical position). At this time, a gap 300 is formed between the plate-shaped structure 90 and the upper louver 70. Next, the control unit 210 drives the motor M1 via the vertical wind direction plate motor drive circuit 220, and as shown in FIG. 11, slightly rotates (lifts) the upper louver 70 upward. The position is such that the gap 300 between the plate-shaped structure 90 and the upper louver 70 becomes smaller. As a result, it is possible to set a state in which a "jet stream" as shown in FIG. 5 can be generated. The gap 300 between the plate-shaped structure 90 and the upper louver 70 may be completely closed. That is, in a state where the upper flow path is closed, the gap 300 between the plate-shaped structure 90 and the upper louver 70 can be appropriately set according to the degree of deceleration of the blown airflow or the flow rate. Therefore, the operating state shown in FIG. 11 is a usage mode (second operating mode) that provides a comfortable air-conditioned environment. Here, it is assumed that the plate-shaped structure 90 is opened as a continuation of the initial operation, but it may be opened based on, for example, an operation from the remote controller device 270. Further, after setting the state in FIG. 11, the cross flow fan 60 may be driven.

このように、上側流路を遮るように貫通孔９０ｃが設けられた板状構造体９０を配置することで、上側流路に流入した空気は板状構造体９０の流路が小さい貫通孔９０ｃを通って流れることになり、流速が増大したジェット状の噴流状の流れとなる。この噴流状の流れ（ジェット気流）は、貫通孔９０ｃの面積や数を変化させることで、下流側の広がり具合や、減衰の程度を調整することができる。 By arranging the plate-shaped structure 90 provided with the through hole 90c so as to block the upper flow path in this way, the air flowing into the upper flow path is the through hole 90c in which the flow path of the plate-shaped structure 90 is small. It will flow through, resulting in a jet-like jet-like flow with increased flow velocity. By changing the area and the number of through holes 90c, the jet stream can be adjusted in terms of the degree of spread on the downstream side and the degree of attenuation.

そして、図５で説明したように、下側の流路を流出した気流は、通常の空調機と気流と同様になるが、板状構造体９０の貫通孔９０ｃを調整して、上側流路から流出したジェット気流の流れを拡大させて下側の流路を流れる気流と混合させることで、下側流路から流出した気流の減衰の程度を調整することができる。すなわち、板状構造体９０の貫通孔９０ｃを調整することで、上側流路からの気流および下側流路からの気流の両方の減衰の程度を調整することができる。そして、人体に当たる恐れがある距離において、十分減衰して流速が低下するように貫通孔９０ｃを設計配置すれば、人体に当たる際の不快感を低減させることができる。これにより、部屋の中に複数の人が居た場合でも、特定の人だけではなく、全員に通常の気流が当たることを抑制でき、不快感を覚える人の数を低減できる。また、下側流路により気流の流量を確保でき、所定の設定温度に到達させ難くなることを抑制できる。さらに、人体に気流が当たりにくくする場合と比べて、気流のにおいに気づき易くなり、フィルターの汚れに気づき易くなる。なお、第２の動作モードは、冷房運転時および暖房運転時の両方で作動させることもできるが、特に冷房運転時に不快感を覚える人が多いため、冷房運転時のみで作動させるようにしても良い。 Then, as described with reference to FIG. 5, the airflow flowing out of the lower flow path is the same as that of a normal air conditioner, but the through hole 90c of the plate-shaped structure 90 is adjusted to adjust the upper flow path. By expanding the flow of the jet stream flowing out from the air conditioner and mixing it with the air flow flowing through the lower flow path, the degree of attenuation of the air flow flowing out from the lower flow path can be adjusted. That is, by adjusting the through hole 90c of the plate-shaped structure 90, it is possible to adjust the degree of attenuation of both the airflow from the upper flow path and the airflow from the lower flow path. Then, if the through holes 90c are designed and arranged so that the through holes 90c are sufficiently damped and the flow velocity is reduced at a distance where they may hit the human body, the discomfort when hitting the human body can be reduced. As a result, even if there are a plurality of people in the room, it is possible to suppress the normal airflow from hitting not only a specific person but all of them, and it is possible to reduce the number of people who feel uncomfortable. In addition, the flow rate of the air flow can be secured by the lower flow path, and it is possible to prevent it from becoming difficult to reach a predetermined set temperature. Further, as compared with the case where the airflow is less likely to hit the human body, the odor of the airflow is more easily noticed, and the dirt on the filter is more easily noticed. The second operation mode can be operated during both the cooling operation and the heating operation, but since many people feel uncomfortable especially during the cooling operation, even if the operation is performed only during the cooling operation. good.

実施形態の変形例として、板状構造体９０の設置位置を変更させる機構に対して、任意のタイミングにおいて板状構造体９０で上側流路を防ぐか否かを変更してもよい。上側流路を塞がない場合（第１の動作モード）は、気流に対する抵抗が小さくなるため、より多い空気流量を流したい場合や、ファンの消費電力を節約したい場合に有効となる。また、板状構造体９０の設置位置を変更させる機構としては、板状構造体９０を回転軸で保持し、その回転軸をモータのような回転機構に接続する構造としたが、他の折り畳み機構であってもよい。 As a modification of the embodiment, with respect to the mechanism for changing the installation position of the plate-shaped structure 90, it may be changed whether or not the plate-shaped structure 90 prevents the upper flow path at an arbitrary timing. When the upper flow path is not blocked (first operation mode), the resistance to the air flow becomes small, which is effective when it is desired to flow a larger air flow rate or when it is desired to save the power consumption of the fan. Further, as a mechanism for changing the installation position of the plate-shaped structure 90, the plate-shaped structure 90 is held by a rotating shaft, and the rotating shaft is connected to a rotating mechanism such as a motor. It may be a mechanism.

実施形態の室内機の構造によれば、板状構造体で塞がれた流路に流入した空気は、板状構造体に設けられた貫通孔を通ることでジェット気流となる。ジェット気流の流れは、広がりや減衰の程度を貫通孔の大きさや数により調整できるため、板状構造体が設けられていない流路を通る気流と干渉するような広がりとすれば、横流ファンによって生じるすべての気流を人体に当たる前に減衰させることができる。 According to the structure of the indoor unit of the embodiment, the air flowing into the flow path blocked by the plate-shaped structure becomes a jet stream by passing through the through hole provided in the plate-shaped structure. Since the degree of spread and attenuation of the jet stream can be adjusted by adjusting the size and number of through holes, if the spread is such that it interferes with the air flow passing through the flow path without a plate-like structure, a cross flow fan is used. All generated airflow can be damped before it hits the human body.

このように、ジェット気流の流れとすることにより、気流を周囲の空気との混合を促進して意図的に減衰させることで、人体に気流を向けた場合も人体表面に気流が到達する際には、十分流速が落ちた気流にすることができる。 In this way, by making the flow of the jet stream, the airflow is promoted to mix with the surrounding air and intentionally attenuated, so that even when the airflow is directed to the human body, when the airflow reaches the surface of the human body. Can be an airflow with a sufficiently low flow velocity.

実施形態の室内機の構造によれば、板状構造体は、フィルター掃除機構よりも後方にあるため、縦方向の省スペース化が可能となる。より後方から気流を拡散させる構造であるため、人体に気流が一層当たりにくくなる。 According to the structure of the indoor unit of the embodiment, since the plate-shaped structure is located behind the filter cleaning mechanism, it is possible to save space in the vertical direction. Since the structure diffuses the airflow from the rear, it becomes more difficult for the airflow to hit the human body.

実施形態の室内機の構造によれば、板状構造体の配置を変更する機構をルーバー制御機構に接続しておくことで、任意のタイミングで板状構造体により流路を塞いだり、流路を開放したりすることができる。また、板状構造体を保持する軸にモータなどの軸を回転させる機構を接続することで、板状構造により流路を塞いだり、流路を開放したりすることができる。また、板状構造体で塞がない場合の流路面積の確保することができる。 According to the structure of the indoor unit of the embodiment, by connecting a mechanism for changing the arrangement of the plate-shaped structure to the louver control mechanism, the flow path can be blocked by the plate-shaped structure at an arbitrary timing. Can be opened. Further, by connecting a mechanism for rotating a shaft such as a motor to a shaft holding the plate-shaped structure, the flow path can be blocked or opened by the plate-shaped structure. In addition, it is possible to secure the flow path area when the plate-shaped structure is not blocked.

ところで、上記の実施形態では、２つのルーバー（上ルーバー７０および下ルーバー８０）により、流路が上側流路と下側流路に区画されたが、これには限られない。例えば、下側に流路を形成するルーバーを設けずに、流路の途中に１つのルーバーを設けることで当該流路を２つに分割することもできる。また、上記の実施形態では、空気吹出し口１００が上側流路と下側流路との２つの流路に分割されたが、これには限られない。例えば、空気吹出し口を３つ以上の流路に分割することができる。この場合、少なくとも１つ以上の流路を開閉可能に板状構造体が配置される。すなわち、複数の流路を備え、これらの流路のうち少なくとも１つ以上の流路に、流路を塞いだ状態と塞いでいない状態とに変換可能な板状構造体を配置して、複数の流路のうち少なくとも１つ以上の流路を板状構造体により塞ぐとともに、板状構造体の有無に関わらず、残りの流路を板状構造体により塞がずに気流が通過できるモードを備えていればよい。これにより、板状構造体により塞がれた流路を通過した気流と、板状構造体により塞がれていない流路を通過した気流とを混合することができ、ジェット気流を発生させることができる。その結果、気流の流速を減衰させることができ、人が不快に感じることを抑制できる。 By the way, in the above embodiment, the flow path is divided into an upper flow path and a lower flow path by two louvers (upper louver 70 and lower louver 80), but the present invention is not limited to this. For example, the flow path can be divided into two by providing one louver in the middle of the flow path without providing the louver that forms the flow path on the lower side. Further, in the above embodiment, the air outlet 100 is divided into two flow paths, an upper flow path and a lower flow path, but the present invention is not limited to this. For example, the air outlet can be divided into three or more flow paths. In this case, the plate-like structure is arranged so that at least one or more flow paths can be opened and closed. That is, a plurality of plate-shaped structures are provided, and at least one or more of these flow paths can be converted into a state in which the flow paths are closed and a state in which the flow paths are not closed. A mode in which at least one or more of the flow paths of the above are blocked by a plate-shaped structure, and the remaining flow paths can pass through without being blocked by the plate-shaped structure regardless of the presence or absence of the plate-shaped structure. It suffices to have. As a result, the airflow that has passed through the flow path blocked by the plate-shaped structure and the airflow that has passed through the flow path that is not blocked by the plate-shaped structure can be mixed, and a jet stream can be generated. Can be done. As a result, the flow velocity of the air flow can be attenuated, and it is possible to suppress the person from feeling uncomfortable.
