現在、家庭用の空気調和機は、室内の空気質の向上が求められ、室内に浮遊する通常の塵埃はもとより、より微細な花粉やハウスダストのようなアレルゲンも除去することも要求されるようになった。加えて、外観も重視され、不使用時はもとより、使用中も室内の雰囲気を乱さない製品が求められている。   Currently, home air conditioners are required to improve indoor air quality, and it is also required to remove finer pollen and house dust allergens as well as normal dust floating in the room. Became. In addition, the appearance is also emphasized, and there is a demand for products that do not disturb the indoor atmosphere during use as well as when not in use.

また、環境への配慮も要求され、容易にメンテナンスの作業ができるようにして、購入時の性能を維持し続け、寿命を長期化して、廃棄することによる環境への負荷を軽減することも求められている。   In addition, consideration for the environment is required, and maintenance work can be easily performed to maintain the performance at the time of purchase, to prolong the service life, and to reduce the environmental impact of disposal. It has been.

特許文献1では室内から見え易い前面に吸込み口の格子が有り、吸込み口のため室内の埃が付き易く、室内の雰囲気を乱すうえ、上面から前面にかけて大きな面積のフィルターが必要となり、省資源に反する。また、フィルターの着脱についての言及は無い。   In Patent Document 1, there is a grid of air inlets on the front surface that is easily visible from inside the room. The air inlets make it easy for dust to accumulate in the room, disturb the indoor atmosphere, and require a large area filter from the top surface to the front surface, saving resources. Contrary. There is no mention of attaching or detaching the filter.

特許文献2では運転時にフロントパネルが1段目まで開くので、空気調和機を斜め前方から見ると、開いたフロントパネルと本体との間から空気調和機の内部が見え、外観を損ねるうえ、上面から前面にかけて大きな面積のフィルターが必要となり、省資源に反する。   In Patent Document 2, since the front panel opens to the first stage during operation, when the air conditioner is viewed obliquely from the front, the inside of the air conditioner can be seen from between the opened front panel and the main body, and the appearance is impaired. A large-area filter is required from the front to the front, which is against resource saving.

特許文献3ではフィルターの清掃についての言及は無いが、この壁掛型の室内機ではフィルターが上部にあるため、フィルターの清掃のためには脚立に登って、更に上部のフィルターに手を伸ばさなければならず姿勢が不安定になり、フィルターの清掃が敬遠され勝ちとなって、初期の性能が段々低下して省エネに反するようになる。また、空気清浄機能についての言及は無い。   In Patent Document 3, there is no mention of filter cleaning, but in this wall-mounted indoor unit, the filter is at the top, so you must climb a stepladder and reach for the filter at the top to clean the filter. However, the posture becomes unstable, and the cleaning of the filter is avoided and prevails, and the initial performance is gradually reduced, which is against energy saving. There is no mention of the air cleaning function.

特許文献4ではフィルターの自動清掃機構により、室内機上部のフィルターの清掃が行われるが、フィルターの清掃時のダストボックスの移動通路をフィルターに沿って設けなければならず、前面下部の熱交換器を通過する室内空気のために、室内空気を上面からのみ吸込むにもかかわらず、フィルターは上側から前側にかけて大きなフィルターを使用し、これに伴って、室内機の奥行き寸法も大きくなり、室内の雰囲気を乱すと共に、省資源にも反する。また、空気清浄機能についての言及は無い。   In Patent Document 4, the filter at the upper part of the indoor unit is cleaned by the automatic filter cleaning mechanism. However, a dust box moving path must be provided along the filter when the filter is cleaned, and a heat exchanger at the lower part of the front surface is provided. Despite inhaling indoor air only from the upper surface due to the passing indoor air, the filter uses a large filter from the upper side to the front side, and along with this, the depth dimension of the indoor unit also increases, and the indoor atmosphere is increased. Disturbs and goes against resource conservation. There is no mention of the air cleaning function.

本発明の目的は、室内の雰囲気を乱すことがなく、経時的な性能劣化の少ない空気調和機を提供し、在室者を快適にするものである。   An object of the present invention is to provide an air conditioner that does not disturb the indoor atmosphere and has little deterioration in performance over time, and makes the occupants comfortable.

以下、本発明の実施例について図を用いて説明する。図における同一符号は同一物または相当物を示す。   Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals in the drawings indicate the same or equivalent.

まず、空気調和機の全体構成について図1,図2,図3,図5を用いて説明する。図1は実施例の空気調和機の構成図である。図2は空気調和機の室内機の側断面図である。図3は室内機の冷房・除湿運転時の側断面図である。図5は室内機の前面パネル跳ね上げ状態を示す斜視図である。   First, the whole structure of an air conditioner is demonstrated using FIG. 1, FIG. 2, FIG. 3, FIG. FIG. 1 is a configuration diagram of an air conditioner according to an embodiment. FIG. 2 is a side sectional view of the indoor unit of the air conditioner. FIG. 3 is a side sectional view of the indoor unit during the cooling / dehumidifying operation. FIG. 5 is a perspective view showing a front panel flip-up state of the indoor unit.

空気調和機1は、室内機2と室外機6とを接続配管8で繋ぎ、室内を空気調和する。室内機2は、筐体ベース21の中央部に室内熱交換器33を置き、熱交換器33の下流側に熱交換器33の幅と略等しい長さの横流ファン方式の送風ファン311を配置し、露受皿35等を取り付け、これらを化粧枠23で覆い、化粧枠23の前面に前面パネル25を取り付けている。この化粧枠23には、室内空気を吸い込む空気吸込み口27と、温湿度が調整された空気を吹出す空気吹出し口29とが上下に設けられている。   The air conditioner 1 connects the indoor unit 2 and the outdoor unit 6 with a connection pipe 8 to air-condition the room. In the indoor unit 2, an indoor heat exchanger 33 is placed at the center of the housing base 21, and a cross-flow fan type blower fan 311 having a length substantially equal to the width of the heat exchanger 33 is disposed on the downstream side of the heat exchanger 33. Then, a dew tray 35 and the like are attached, these are covered with a decorative frame 23, and a front panel 25 is attached to the front surface of the decorative frame 23. The decorative frame 23 is provided with an air inlet 27 for sucking in indoor air and an air outlet 29 for blowing air with adjusted temperature and humidity.

室内熱交換器33は、室内機2のスペースを有効に使用してできるだけ伝熱面積が広くなるように、上方に突の形状とし、送風ファン311を跨ぐように設置されている。送風ファン311は吹出し気流を送風ファン311の長さに略等しい幅を持つ吹出し風路290に流し、吹出し気流は吹出し風路290途中に配した左右風向板295で気流の左右方向を偏向され、更に、吹出し口29に配した上下風向板291で気流の上下方向を偏向されて室内に吹出す。   The indoor heat exchanger 33 is installed to protrude upward and straddle the blower fan 311 so as to make the heat transfer area as wide as possible by effectively using the space of the indoor unit 2. The blower fan 311 causes the blown airflow to flow through a blowout air passage 290 having a width substantially equal to the length of the blower fan 311, and the blown airflow is deflected in the left-right direction of the airflow by the left and right wind direction plates 295 arranged in the middle of the blowout air passage 290, Further, the vertical direction of the airflow is deflected by the vertical airflow direction plate 291 disposed at the air outlet 29 and is blown into the room.

送風ファン311が回転すると室内空気が室内機2に設けられた空気吸込み口27から室内熱交換器33、送風ファン311を通って空気吹出し口29から吹出される。   When the blower fan 311 rotates, room air is blown from the air blowout port 29 through the indoor heat exchanger 33 and the blower fan 311 from the air suction port 27 provided in the indoor unit 2.

筐体ベース21には、送風ファン311,フィルター231,室内熱交換器33,露受皿35,上下風向板291,左右風向板295等の基本的な内部構造体が取り付けられる。そして、これらの基本的な内部構造体は、筐体ベース21,化粧枠23,前面パネル25からなる筐体20に内包され室内機2を構成する。   Basic internal structures such as a blower fan 311, a filter 231, an indoor heat exchanger 33, a dew tray 35, an up / down air direction plate 291, and a left / right air direction plate 295 are attached to the housing base 21. These basic internal structures are included in a casing 20 including a casing base 21, a decorative frame 23, and a front panel 25, thereby constituting the indoor unit 2.

また、前面パネル25の下部一側には、図5に示すように運転状況を表示する表示部397と、別体のリモコン5からの赤外線の操作信号を受ける受光部396とが配置されている。   Further, on the lower side of the front panel 25, as shown in FIG. 5, a display unit 397 for displaying an operation status and a light receiving unit 396 for receiving an infrared operation signal from a separate remote controller 5 are arranged. .

化粧枠23の下面に形成される空気吹出し口29は、前面パネル25との分割部に隣接して配置され、奥の吹出し風路290に連通している。上下風向板291は、閉鎖状態で、吹出し風路290をほぼ隠蔽して室内機2の底面に連続する大きな曲面を有するように構成されている。これらの上下風向板291は、両端部に設けた回動軸を支点にして、リモコン5からの指示に応じて、駆動モータにより空気調和機1の運転時に所要の角度回動して空気吹出し口29を図3の如く開き、その状態に保持する。空気調和機1の運転停止時には、これらの上下風向板291は空気吹出し口29を閉じるように制御される。   An air outlet 29 formed on the lower surface of the decorative frame 23 is disposed adjacent to the divided portion with the front panel 25 and communicates with the rear outlet air passage 290. The up-and-down wind direction plate 291 is configured to have a large curved surface that is substantially concealed from the blowing air passage 290 and is continuous with the bottom surface of the indoor unit 2 in the closed state. These up-and-down wind direction plates 291 are pivoted at a required angle when the air conditioner 1 is operated by a drive motor in response to an instruction from the remote controller 5 with pivot shafts provided at both ends as fulcrums. 29 is opened as shown in FIG. 3 and held in that state. When the operation of the air conditioner 1 is stopped, the up-and-down air direction plates 291 are controlled so as to close the air outlet 29.

左右風向板295は、下端部に設けた回動軸を支点にして駆動モータにより回動され、リモコン5からの指示の応じて回動されてその状態に保持される。これによって、吹出し空気が左右の所望の方向に吹出される。なお、リモコン5から指示することにより、空気調和機1の運転中に上下風向板291,左右風向板295を周期的に揺動させ、室内の広範囲に周期的に吹出し空気を送ることもできる。   The left and right wind direction plates 295 are rotated by a drive motor with a rotation shaft provided at the lower end portion as a fulcrum, and are rotated in accordance with an instruction from the remote controller 5 and held in that state. As a result, the blown air is blown out in the left and right desired directions. By instructing from the remote controller 5, the up and down wind direction plate 291 and the left and right wind direction plate 295 can be periodically oscillated during the operation of the air conditioner 1, and the blown air can be periodically sent over a wide range in the room.

室内機2は、内部の電装品ボックスに制御基板を備え、この制御基板にマイコンが設けられる。このマイコンは、室内温度センサー、室内湿度センサー等の各種のセンサーからの信号を受けると共に、リモコン5からの操作信号を受光部396を介して受ける。このマイコンは、これらの信号に基づいて、室内送風ファン311,上下風向板駆動モータ,左右風向板駆動モータ等を制御すると共に、室外機6との通信を司り、室内機2を統括して制御する。   The indoor unit 2 includes a control board in an internal electrical component box, and a microcomputer is provided on the control board. The microcomputer receives signals from various sensors such as an indoor temperature sensor and an indoor humidity sensor, and receives an operation signal from the remote controller 5 via the light receiving unit 396. Based on these signals, the microcomputer controls the indoor blower fan 311, the up / down wind direction plate drive motor, the left / right wind direction plate drive motor, etc., and controls the communication with the outdoor unit 6, and controls the indoor unit 2 as a whole. To do.

フィルター231は、吸い込まれた室内空気中に含まれる塵埃を取り除くためのものであり、空気吸込口に配置されている。露受皿35は、室内熱交換器33の前後両側の下端部下方に配置され、冷房運転時や除湿運転時に室内熱交換器33に発生する凝縮水を受けるために設けられている。受けて集められた凝縮水はドレン配管37を通して室外に排出される。   The filter 231 is for removing dust contained in the sucked room air, and is disposed at the air suction port. The dew tray 35 is disposed below the lower ends of the front and rear sides of the indoor heat exchanger 33, and is provided to receive condensed water generated in the indoor heat exchanger 33 during cooling operation or dehumidifying operation. The condensed water received and collected is discharged to the outside through the drain pipe 37.

次に、本実施例が備える空気質の向上を図って付加される機能部材の収納構造について図2〜図4を用いて説明する。図4は室内機の前面パネル跳ね上げ状態を示す側断面図である。   Next, a functional member storage structure added to improve the air quality of the present embodiment will be described with reference to FIGS. FIG. 4 is a side sectional view showing a state in which the front panel of the indoor unit is flipped up.

前述したように、昨今の空気調和機には室内の温湿度の調節の他に、室内の空気質の向上も期待されている。空気質の向上を果たすものとして、花粉やハウスダスト等のアレルゲンを除去する空気清浄機能や脱臭,マイナスイオン付加,帯電微細水滴の付加,加湿等の様々な機能が考えられるが、ここでは、粒径10μm以上の塵埃を99.9%に近い高効率で捕集することができ、更に、脱臭機能も有する空気清浄フィルターを例にとり説明する。   As described above, recent air conditioners are expected to improve indoor air quality in addition to adjusting indoor temperature and humidity. In order to improve air quality, there are various functions such as air cleaning function to remove allergens such as pollen and house dust, deodorization, negative ion addition, addition of charged fine water droplets, humidification, etc. An air cleaning filter that can collect dust with a diameter of 10 μm or more with a high efficiency close to 99.9% and also has a deodorizing function will be described as an example.

空気清浄フィルター331は不織布に脱臭剤を含ませ、プリーツ状にひだ折し、静電気を帯電させたもので、空気清浄機能を有している。この空気清浄フィルター331を熱交換器33の上流側の下部と吸込み口27に設けたフィルター231との間の風路に臨ませる。具体的には該風路を構成する閉鎖部材333に通風自在の支持枠333cを形成し、該支持枠333cに空気清浄フィルター331を懸架し、収納する。   The air cleaning filter 331 is a non-woven fabric containing a deodorizing agent, folded in a pleat shape and charged with static electricity, and has an air cleaning function. This air purifying filter 331 is made to face the air path between the lower part on the upstream side of the heat exchanger 33 and the filter 231 provided in the suction port 27. Specifically, a support frame 333c that allows ventilation is formed in the closing member 333 that constitutes the air passage, and the air purifying filter 331 is suspended and stored in the support frame 333c.

これにより、空気調和機を運転したときに、送風ファン311によって引起される気流は図3の矢印で示すように、その一部が空気清浄フィルター331を通過し、通過する気流に含まれる花粉やハウスダスト等のアレルゲンを除去すると共に、臭気成分を捕らえ、脱臭作用を発現する。この空気清浄フィルター331は長期の使用により、前記の花粉やハウスダスト等の塵埃が蓄積されるので2〜3年に1度くらいの頻度で水洗いするなどの清掃をする必要がある。   Thereby, when the air conditioner is operated, the air flow caused by the blower fan 311 partially passes through the air cleaning filter 331 as shown by the arrow in FIG. While removing allergens such as house dust, it captures odor components and develops deodorizing action. Since the air cleaning filter 331 accumulates dust such as pollen and house dust due to long-term use, it is necessary to perform cleaning such as washing with water about once every two to three years.

このため、空気清浄フィルター331の収納部333bに収納された空気清浄フィルター331を前面パネル25側から着脱できるように、閉鎖部材333の適所に空気清浄フィルター331着脱用の開口333aを設ける。この着脱用の開口333aには蓋部材335を着脱自在に取り付ける。また、前面パネル25は図4のように上部を化粧枠23の上側前部に軸支され、下部を閉鎖部材333に材料のバネ性を利用するなどして跳ね上げるように開閉が自在に構成される。このようにすることで、空気清浄フィルター331の清掃時には、工具を使用することなく、空気清浄フィルター331を簡単に着脱できる。   For this reason, the opening 333a for attaching / detaching the air cleaning filter 331 is provided at an appropriate position of the closing member 333 so that the air cleaning filter 331 stored in the storage portion 333b of the air cleaning filter 331 can be attached / detached from the front panel 25 side. A lid member 335 is detachably attached to the opening 333a for attachment / detachment. Further, as shown in FIG. 4, the front panel 25 is pivotally supported at the upper part by the upper front part of the decorative frame 23, and the lower part can be freely opened and closed so that the closing member 333 springs up by utilizing the spring property of the material. Is done. By doing in this way, at the time of cleaning of the air purifying filter 331, the air purifying filter 331 can be easily attached or detached without using a tool.

このように、蓋部材333と前面パネル25を共に着脱自在に構成しても、一方の蓋部材335は寸法が小さい上、着脱の相手が閉鎖部材333だけで、且つ、閉鎖部材333との接触部を同一平面に形成するなどして密着性を高め、空気漏れを少なくできるのに対して、他方の前面パネル25は寸法が大きい上、室内機2の本体に密着させようとすると、密着させる相手の部品が多岐に渡り、また、外観に美観を与えるために形状も複雑になりがちで、着脱自在にするための小さな力で、これらを密着させて空気漏れを少なくすることは到底できない。   As described above, even if the lid member 333 and the front panel 25 are both configured to be detachable, the one lid member 335 has a small size, and the detachable partner is only the closing member 333 and is in contact with the closing member 333. The other front panel 25 has a large size and is in close contact with the main body of the indoor unit 2, while it can improve the adhesion by forming the part on the same plane and reduce air leakage. There are a wide variety of other parts, and the shape tends to be complicated to give an aesthetic appearance, and it is impossible to reduce air leakage by bringing them into close contact with each other with a small force to make them detachable.

一般に、送風機を運転すると送風機の吸込み側と吸込み口の間に気流が引起され、この気流によって圧力差が生じ、送風機と吸込み口との間わずかな隙間から周囲の空気が吸込まれ、吸込み口を通らない空気も送風機に吸込まれ吹出される。空気調和機においては、この吸込み口を通らない空気はフィルターを通過していない空気で、塵埃が多く含まれているので熱交換器や筐体の通風路に付着し、汚れの原因になる。また、吸込み口を通らない空気は空気調和機のフィルターで室内空気を浄化すると言う作用を全く受けないため、室内空気の浄化作用が減殺される。このため、吸込み口を通らない空気の吸込みはできるだけ排除することが望ましいが、前述したような製造上の制約から根絶することは困難である。   In general, when a blower is operated, an air flow is generated between the suction side and the suction port of the blower, a pressure difference is generated by this air flow, and ambient air is sucked from a slight gap between the blower and the suction port, and the suction port is Air that does not pass is sucked into the blower and blown out. In the air conditioner, the air that does not pass through the suction port is air that has not passed through the filter and contains a large amount of dust, so that it adheres to the heat exchanger and the ventilation path of the housing and causes contamination. In addition, since the air that does not pass through the suction port is not subjected to the action of purifying the room air with the filter of the air conditioner, the action of purifying the room air is diminished. For this reason, it is desirable to eliminate as much as possible the suction of air that does not pass through the suction port, but it is difficult to eradicate it from the above-mentioned manufacturing restrictions.

他方、空気調和機を据付けた後の保守作業を容易にして、初期の性能を維持することが環境への負荷を軽くする重要な役割を担うことから、保守作業に関わる部分は工具なしで着脱自在にすることが強く求められている。このため、前面パネルの工具を使用することなしに跳ね上げて、内部の保守点検作業を行えるようにしている。このようにした場合、面積の広い前面パネルを容易に着脱させるため、前面パネルと本体側を密着させることができず、本体側との間に隙間ができてしまう。この隙間から吸込み口を通らない空気が吸込まれ、内部の汚れを助長する。   On the other hand, the maintenance work after the air conditioner is installed is easy, and maintaining the initial performance plays an important role in reducing the burden on the environment. There is a strong demand for freedom. For this reason, it is possible to perform internal maintenance and inspection work by flipping up without using a tool on the front panel. In this case, since the front panel having a large area is easily attached and detached, the front panel and the main body side cannot be brought into close contact with each other, and a gap is formed between the main body side. Air that does not pass through the suction port is sucked from this gap, and promotes dirt inside.

上述の保守作業時の簡便性と、空気漏れを抑える密着性と言う2つの相反する要求にこたえるため、本発明では閉鎖部材333を前面パネル25と熱交換器33の間に設ける。閉鎖部材333は下部を露受皿35に、上部を後述するフィルター231の清掃機構の案内枠234に密着して係止され、前面から熱交換器33に入る漏れ空気をほぼ完全に遮断している。これにより、フィルター231を通らないで直接熱交換器33に流れる漏れ空気が少なくなり、熱交換器33や室内機2内の汚れが軽減され、フィルター231での空気の浄化作用も減殺されない。   In the present invention, the closing member 333 is provided between the front panel 25 and the heat exchanger 33 in order to meet the two contradicting demands of the above-described simplicity during maintenance work and adhesion that suppresses air leakage. The closing member 333 is locked in close contact with the dew receiving tray 35 at the lower part and the guide frame 234 of the cleaning mechanism of the filter 231 described later, and almost completely blocks leaked air entering the heat exchanger 33 from the front. . As a result, the amount of leaked air that flows directly to the heat exchanger 33 without passing through the filter 231 is reduced, dirt in the heat exchanger 33 and the indoor unit 2 is reduced, and the air purification action in the filter 231 is not diminished.

この時、前面パネル25や蓋部材335を着脱自在に係止するため、閉鎖部材333に孔等を設けるが、これらの孔の面積は前面パネルと室内機2の本体との間に生ずる隙間に比べるとはるかに小さく、なおかつ、これらの孔には前面パネル25や蓋部材335の係止部が嵌合するため、隙間の面積は更に小さくなるので、これらの孔からの空気漏れは非常に少ない。しかし、これらの孔の面積はは必要最小限にすることが望ましく、いたずらに必要以上の大きな孔を開けるべきではない。   At this time, in order to detachably lock the front panel 25 and the lid member 335, holes or the like are provided in the closing member 333. The area of these holes is a gap generated between the front panel and the main body of the indoor unit 2. The holes are much smaller than the above, and the engaging portions of the front panel 25 and the lid member 335 are fitted into these holes, so that the area of the gap is further reduced, so that air leakage from these holes is very small. . However, it is desirable to minimize the area of these holes and should not unnecessarily make holes larger than necessary.

一連の空気清浄フィルターの着脱作業を図5〜図7を用いて説明する。図6は室内機の蓋部材脱着説明図である。図7は室内機の空気清浄フィルター交換作業説明図、(b)は清掃機構の集塵ボックスの斜視図、(c)は清掃機構の掃除用刷毛の斜視図である。   A series of attaching / detaching operations of the air purifying filter will be described with reference to FIGS. FIG. 6 is an explanatory view of attaching and detaching the lid member of the indoor unit. FIG. 7 is an explanatory diagram of an air cleaning filter replacement operation of the indoor unit, (b) is a perspective view of a dust collection box of the cleaning mechanism, and (c) is a perspective view of a cleaning brush of the cleaning mechanism.

空気清浄フィルター331を装着する場合は、先ず、前面パネル25を図5のように開き、現れた、蓋部材335のつまみを持って手前に引き、図6のように蓋部材335を引き外す。開口333aから図7のように空気清浄フィルター331を挿入して収納部333bに空気清浄フィルター331を取り付ける。これを清掃する場合は逆の順序で空気清浄フィルター331を取外し、水洗いして乾燥させてから収納部333bに戻す。このように、空気清浄フィルター331の清掃作業は工具を使用せずに行うことができ、その頻度も2〜3年に1回程度であるので使用者の負担となる程でもない。   When the air purifying filter 331 is attached, first, the front panel 25 is opened as shown in FIG. 5, and the lid member 335 that has appeared is pulled forward with the knob of the lid member 335, and the lid member 335 is removed as shown in FIG. The air purification filter 331 is inserted from the opening 333a as shown in FIG. 7, and the air purification filter 331 is attached to the storage portion 333b. When cleaning this, the air purification filter 331 is removed in the reverse order, washed with water and dried, and then returned to the storage portion 333b. As described above, the cleaning operation of the air purification filter 331 can be performed without using a tool, and the frequency thereof is about once every two to three years, so that it is not a burden on the user.

次に、フィルターの清掃手段について図8を用いて説明する。図8は室内機のフィルター清掃機構部斜視図である。   Next, the filter cleaning means will be described with reference to FIG. FIG. 8 is a perspective view of the filter cleaning mechanism of the indoor unit.

実施例では空気吸込み口27に、平面状のフィルター231を設ける。フィルター231は案内枠234に係着され、案内枠234は後部と前部にレールを、前部のレールに並べてレールに平行な推進軸を備える。   In the embodiment, a planar filter 231 is provided at the air suction port 27. The filter 231 is engaged with the guide frame 234, and the guide frame 234 includes a rear and front rails, and a propulsion shaft that is arranged in parallel with the rails on the front rail.

推進軸は多角形断面を有し、案内枠234に設けた軸受に軸支され、片側の軸受を貫通した一端に取り付けた歯車を介して、案内枠234に固定した移動用モータに連結される。推進軸にはスクリュウ,キャリッジが緩装され、スクリュウは案内枠234に設けられた、推進軸と平行なラックに噛合している。   The propulsion shaft has a polygonal cross section, is pivotally supported by a bearing provided in the guide frame 234, and is connected to a moving motor fixed to the guide frame 234 via a gear attached to one end passing through the bearing on one side. . A screw and a carriage are loosely mounted on the propulsion shaft, and the screw meshes with a rack provided on the guide frame 234 and parallel to the propulsion shaft.

キャリッジとレールとの間には刷毛支持枠262がフィルター231を跨いで懸架され、刷毛支持枠262にはフィルター231を掃いて掃除する掃除用刷毛267が取り付けられている。   A brush support frame 262 is suspended across the filter 231 between the carriage and the rail, and a cleaning brush 267 that sweeps and cleans the filter 231 is attached to the brush support frame 262.

しかして、移動用モータを回転させることで、推進軸,スクリュウが回転し、ラックに沿って、スクリュウが移動用モータの回転方向に応じて左右方向に動き、キャリッジを移動させる。これにより、掃除用刷毛267がフィルター231に摺接しながら掃くように移動し、フィルター231上の塵埃を掃除用刷毛267に掃き取り、案内枠234の左部の除塵ブラシ270に移動させる。   Thus, by rotating the moving motor, the propulsion shaft and the screw rotate, and the screw moves in the left-right direction along the rack according to the rotation direction of the moving motor, thereby moving the carriage. As a result, the cleaning brush 267 moves so as to sweep while being in sliding contact with the filter 231, the dust on the filter 231 is swept by the cleaning brush 267, and moved to the dust removing brush 270 on the left side of the guide frame 234.

掃除用刷毛267の毛は柔らかな毛を使用し、フィルター231面に掃除用刷毛267を押し付けて移動したときに、フィルター231が掃除用刷毛267の押付けで変形した後も適度な重複代を確保できるようフィルター231の剛性に合わせて選定するのが良い。ここで重複しろとは掃除用刷毛267の毛が変形しないで真直ぐな状態と仮定したときのフィルター面から毛先迄の長さを言う。   The bristles of the cleaning brush 267 use soft bristles, and when the cleaning brush 267 is pressed against the surface of the filter 231 and moved, the filter 231 can be secured even after being deformed by the pressing of the cleaning brush 267. It is good to select according to the rigidity of the filter 231 so that it can do. Here, “overlapping” means the length from the filter surface to the tip of the hair when it is assumed that the hair of the cleaning brush 267 is straight without deformation.

このように、掃除用刷毛267に軟毛を使用するので、フィルター231を変形させる力が小さく、フィルター231を片側から掃くだけでよく、フィルター231を裏側から支えなくてもフィルター231上の塵埃を掃き取ることができる。このため、掃除用刷毛267でフィルター231を掃引する時の駆動機構をフィルター231の片側だけに設ければ良く、駆動機構が大幅に簡略化される。   Thus, since soft hair is used for the cleaning brush 267, the force for deforming the filter 231 is small, and it is only necessary to sweep the filter 231 from one side, and the dust on the filter 231 can be swept without supporting the filter 231 from the back side. Can be taken. For this reason, a drive mechanism for sweeping the filter 231 with the cleaning brush 267 may be provided only on one side of the filter 231, and the drive mechanism is greatly simplified.

次に、清掃機構の構成及び動作について図9を用いて説明する。図9は清掃機構の捕集塵埃の掃き取り動作詳細図である。   Next, the configuration and operation of the cleaning mechanism will be described with reference to FIG. FIG. 9 is a detailed view of the sweeping operation of the collected dust of the cleaning mechanism.

フィルター231の右方には清掃動作が行われていない時に掃除用刷毛267が待機する待機部238がある。待機部238は図9のF部に示す如く、フィルターの面より窪んだ凹所F234fが設けられ、フィルター231に摺接している時に図9のE部に示す如く曲げられた掃除用刷毛267が図9のF部に示す如く開放されて真直ぐな状態に復元する。   On the right side of the filter 231 is a standby unit 238 on which the cleaning brush 267 waits when the cleaning operation is not performed. The standby portion 238 is provided with a recess F234f that is recessed from the surface of the filter as shown in F portion of FIG. 9, and a cleaning brush 267 that is bent as shown in E portion of FIG. As shown in part F of FIG. 9, it is opened and restored to a straight state.

これにより、掃除用刷毛267が待機している間、掃除用刷毛267を曲げる力が働かず、掃除用刷毛267に曲げ癖が付かない。また、フィルター231上を移動した時にフィルター231の網目で捻られたりして生ずる毛先の変形も復元し、整えられる。   Thereby, while the cleaning brush 267 is on standby, the force for bending the cleaning brush 267 does not work, and the cleaning brush 267 is not bent. Further, the deformation of the hair ends caused by twisting at the mesh of the filter 231 when moving on the filter 231 is restored and arranged.

このため、清掃動作の度に掃除用刷毛267がフィルター231に所定の状態で摺接し、清掃動作が安定し、所期の清掃性能を発揮できる。更に、待機部238では掃除用刷毛267の毛先が開放されるので、凹所F234fが無く毛先が曲がったままの場合に比べて、掃除用刷毛267が反転移動を開始する時に毛先が乱れて不要な力を掛けることが無いので掃除用刷毛267の駆動機構に余分な負荷を掛けず、駆動機構の信頼性が向上する。   For this reason, the cleaning brush 267 is in sliding contact with the filter 231 in a predetermined state each time the cleaning operation is performed, the cleaning operation is stabilized, and the desired cleaning performance can be exhibited. Further, since the tip of the cleaning brush 267 is opened in the standby unit 238, the tip of the cleaning brush 267 starts reversing as compared with the case where the tip of the cleaning brush 267 is bent without the recess F234f. Since it is not disturbed and an unnecessary force is not applied, an extra load is not applied to the drive mechanism of the cleaning brush 267, and the reliability of the drive mechanism is improved.

また、掃除用刷毛267の反転時に毛先に不要な力を掛けないので毛先の劣化が生じ難く、掃除用刷毛267を交換する間隔を長くすることができる。また、フィルター231と除去ブラシ271の間に凹所C234cが設けられている。凹所C234cの深さは、除去ブラシ面271aが掃除用刷毛267側に最大露出となる除去ブラシ271の回動位置で、除去ブラシ面271aの頂上部がフィルター231面と略等しくなるようにし、掃除用刷毛267の毛先が凹所C234cの底部に届く範囲にする。   Further, since unnecessary force is not applied to the hair tips when the cleaning brush 267 is reversed, the tip of the hair is hardly deteriorated, and the interval for replacing the cleaning brush 267 can be increased. A recess C234c is provided between the filter 231 and the removal brush 271. The depth of the recess C234c is such that the top surface of the removal brush surface 271a is substantially equal to the surface of the filter 231 at the rotation position of the removal brush 271 where the removal brush surface 271a is exposed to the maximum at the cleaning brush 267 side. The tip of the cleaning brush 267 is set to reach the bottom of the recess C234c.

このようにすることにより、掃除用刷毛267をフィルター231の掃引時以上には変形させること無く掃除用刷毛267を除去ブラシ271に摺接でき、掃除用刷毛271に過度の変形を与えることが無く、掃除用刷毛271の劣化を抑制できる。また、凹所C234cの深さの分だけ除去ブラシ271を掃除用刷毛267側に露出させることができ、除去ブラシ面271aの面積が大きくなり、安定した塵埃236の除去性能を発揮することができる。   By doing so, the cleaning brush 267 can be slidably contacted with the removal brush 271 without deforming the cleaning brush 267 more than when the filter 231 is swept, and the cleaning brush 271 is not excessively deformed. Deterioration of the cleaning brush 271 can be suppressed. Further, the removal brush 271 can be exposed to the cleaning brush 267 side by the depth of the recess C234c, the area of the removal brush surface 271a can be increased, and stable dust 236 removal performance can be exhibited. .

これが清掃動作する時には、待機部238に図9のF部に示す如く待機していた掃除用刷毛267を駆動機構を運転して、フィルター231を掃引するよう図9のD部に示す如く移動させる。この時、掃除用刷毛267の毛先は凹所F234fの開放状態から傾斜F233fを通って突出しているフィルター231面に徐々に毛先を曲げ変形させながら乗り上げ、フィルター231としっかり摺接する。   When the cleaning operation is performed, the cleaning brush 267 that has been waiting as shown in the F part of FIG. 9 is moved to the standby part 238 as shown in the D part of FIG. 9 by operating the drive mechanism and sweeping the filter 231. . At this time, the bristles of the cleaning brush 267 ride on the surface of the filter 231 protruding through the slope F233f from the open state of the recess F234f while gradually bending and deforming the bristles, and make firm sliding contact with the filter 231.

掃除用刷毛267は除塵ブラシ270の方向に移動しながらフィルター231を掃引し、塵埃236を掃き取る。フィルター231の掃引を終了した掃除用刷毛267は掃き取った塵埃236と共に、図9のC部の位置に達し、凹所C234cで若干毛先の変形を開放され、除塵ブラシ270に至り、除去ブラシ面271aと有効に摺接しながら、塵埃236を除去ブラシ271に移載する。   The cleaning brush 267 sweeps the filter 231 and moves the dust 236 while moving in the direction of the dust removing brush 270. The cleaning brush 267 that has finished sweeping the filter 231 reaches the position of the portion C in FIG. 9 together with the dust 236 that has been swept away, the hair tip is slightly deformed in the recess C234c, reaches the dust removal brush 270, and the removal brush The dust 236 is transferred to the removal brush 271 while effectively slidingly contacting the surface 271a.

268は刷毛押えであり、刷毛の片側または両側に設け、清掃動作時の刷毛先端に適度の弾性を与え、塵埃の掃き取り性を良好に維持すると共に、刷毛の根元に過度の変形を与えて、刷毛が根元から折れたりしないようにしている。片側に刷毛押えを設ける場合は、上記の理由から清掃動作時に刷毛の毛先が変形する側に設けるのが良い。また、両側に設けると、清掃動作時と戻り動作時で刷毛の毛先の変形がほぼ同じとなり、刷毛に不均一な癖が付くのを防止できる。   268 is a brush presser, which is provided on one or both sides of the brush to give an appropriate elasticity to the tip of the brush during the cleaning operation, to maintain good dust sweepability, and to give excessive deformation to the base of the brush. The brush does not break from the root. When the brush presser is provided on one side, it is preferably provided on the side where the brush tip is deformed during the cleaning operation for the above-mentioned reason. Further, when provided on both sides, the deformation of the brush tip becomes almost the same during the cleaning operation and the return operation, and it is possible to prevent the brush from being unevenly wrinkled.

刷毛支持枠262はレバー突起269が回動レバー271cを乗り越えたところで停止するが、この部は前述の凹所C234cより窪んだ凹所A234aになっている。凹所A234aでは前述の待機部238の凹所F234fと同様に掃除用刷毛267の毛先は開放され、反転してフィルター231方向に移動を始める。これにより、掃除用刷毛267が停止している間に、掃除用刷毛267は曲がった状態から真直ぐな状態に復元する。また、フィルター231上を移動した時にフィルター231の網目で捻られたりして生ずる毛先の変形も復元し、整えられる。   The brush support frame 262 stops when the lever projection 269 gets over the rotation lever 271c, but this portion is a recess A234a that is recessed from the above-described recess C234c. In the recess A234a, the tip of the cleaning brush 267 is opened like the recess F234f of the standby portion 238 described above, and is inverted to start moving toward the filter 231. Accordingly, while the cleaning brush 267 is stopped, the cleaning brush 267 is restored from the bent state to the straight state. Further, the deformation of the hair ends caused by twisting at the mesh of the filter 231 when moving on the filter 231 is restored and arranged.

更に、掃除用刷毛267が停止している間に毛先が開放されるので、凹所A234aが無く毛先が曲がったままの場合に比べて、掃除用刷毛267が反転移動を開始する時に毛先が乱れて不要な力を掛けることが無いので掃除用刷毛267の駆動機構に余分な負荷を掛けず駆動機構の信頼性が向上する。また、掃除用刷毛267の反転時に毛先に不要な力を掛けないので毛先の劣化が生じ難く、掃除用刷毛267を交換する間隔を長くすることができる。掃除用刷毛267が反転移動する時、掃除用刷毛267の毛先は凹所A234aの開放状態から傾斜A233a,傾斜C233cを通って突出しているフィルター231面に徐々に毛先を曲げ変形させながら乗り上げ、フィルター231としっかり摺接する。   Furthermore, since the bristles are released while the cleaning brush 267 is stopped, the hairs when the cleaning bristles 267 start reversal compared to the case where the recess A234a is not present and the bristles remain bent. Since the tip is not disturbed and unnecessary force is not applied, the drive mechanism of the cleaning brush 267 is not subjected to an excessive load, and the reliability of the drive mechanism is improved. Further, since unnecessary force is not applied to the hair tips when the cleaning brush 267 is reversed, the tip of the hair is hardly deteriorated, and the interval for replacing the cleaning brush 267 can be increased. When the cleaning brush 267 moves in the reverse direction, the tip of the cleaning brush 267 runs from the open state of the recess A234a while gradually bending and deforming the tip of the hair on the surface of the filter 231 protruding through the slopes A233a and C233c. The filter 231 is in sliding contact.

次に掃除用刷毛267は清掃時とは逆向きに毛先を変形させてフィルター231に摺接しながら移動し、待機部238に向かう。このように、掃除用刷毛267は往復で毛先の曲げ方向が逆になるので、片方向でしか摺接させない時に比べて、曲げの癖が付き難く、毎回、フィルター231を押す力を一定にすることができる。このため、フィルター231を清掃する能力を長期間維持することができる。   Next, the cleaning brush 267 moves while sliding in contact with the filter 231 with its tip deformed in the opposite direction to that during cleaning, and heads toward the standby section 238. As described above, the cleaning brush 267 is reciprocated so that the bending direction of the hair tip is reversed. Therefore, compared to the case where the cleaning brush 267 is slidably contacted only in one direction, the bending wrinkles are less likely to occur, and the force for pressing the filter 231 is kept constant each time. can do. For this reason, the ability to clean the filter 231 can be maintained for a long time.

除去ブラシ271により掃除用刷毛267から掻き取られた塵埃236は掃除用刷毛267が戻って行く時に、ブラシホルダー276の内部に押込まれ、集塵ボックス284に落下する。集塵ボックス284に蓄積された塵埃は数年に1度の頻度で前面パネル25を開け、集塵ボックス284のツマミ部284cを持って、除去塵埃排出口281bから集塵ボックス284を引出し、集塵ボックス284の内部の塵埃を捨て清掃する。   The dust 236 scraped from the cleaning brush 267 by the removal brush 271 is pushed into the brush holder 276 when the cleaning brush 267 returns and falls into the dust collection box 284. The dust accumulated in the dust collection box 284 is opened once every few years, the front panel 25 is opened, the knob portion 284c of the dust collection box 284 is held, the dust collection box 284 is pulled out from the removed dust discharge port 281b, and collected. Dust inside the dust box 284 is discarded and cleaned.

かくの如く、室内空気の吸込み口27を上面のみに設け、該吸込み口27に設けたフィルター231の自動清掃機構を設けたことにより、空気調和機の性能維持に欠かせないフィルター231の清掃を、使用者を煩わすことなしに行える。また、閉鎖部材333により前面パネル25側からの空気漏れを抑制して、熱交換器33や室内機2内の汚れを軽減し、空気調和機の所期の性能を長く維持することができる。更に、空気清浄フィルター331を工具を使用することなしに着脱でき、室内の空気質の向上も図ることができる。更にまた、フィルター231を上面のみに設けるので、上面と前面に設けるのに較べてフィルターの大きさを小さくできる。   As described above, the air inlet 27 for indoor air is provided only on the upper surface, and the automatic cleaning mechanism for the filter 231 provided in the air inlet 27 is provided, thereby cleaning the filter 231 indispensable for maintaining the performance of the air conditioner. This can be done without bothering the user. Moreover, the air leakage from the front panel 25 side can be suppressed by the closing member 333, dirt in the heat exchanger 33 and the indoor unit 2 can be reduced, and the expected performance of the air conditioner can be maintained for a long time. Furthermore, the air purification filter 331 can be attached and detached without using a tool, and the indoor air quality can be improved. Furthermore, since the filter 231 is provided only on the upper surface, the size of the filter can be reduced as compared with the case where the filter 231 is provided on the upper surface and the front surface.

このように、実施例の空気調和機は、吸込み口と、フィルターと、熱交換器と、横流型の送風機と、吹出し口を備え、該吸込み口を上面のみに設け、該フィルターの自動清掃機構と、跳ね上げ自在の前面パネルと、上方に突形状にした該熱交換器の間に設けた閉鎖部材とを有し、該閉鎖部材の熱交換器側に設けた機能部材の収納部を前記送風機によって引起される気流に臨ませるごとく配し、該閉鎖部材に前記機能部材着脱用の開口と該開口を閉鎖する蓋部材を備える。   As described above, the air conditioner of the embodiment includes the suction port, the filter, the heat exchanger, the cross-flow type blower, and the blowout port, and the suction port is provided only on the upper surface, and the automatic cleaning mechanism of the filter And a front panel that can be flipped up and a closing member provided between the heat exchangers projecting upward, and a storage portion for the functional member provided on the heat exchanger side of the closing member. The closing member is provided with an opening for attaching and detaching the functional member and a lid member for closing the opening.

これにより、吸込み空気の一部が空気清浄フィルターを通り、気流中に漂っているアレルゲンが除去され、室内が徐々に清浄になり、快適な空間が形成される。このとき、跳ね上げ自在の前面パネルの内側に閉鎖部材を設けているので、吸込み空気は上面の吸込み口からのみ吸込まれ、跳ね上げ自在の前面パネルと本体との隙間から吸込み口を通らない空気が吸込まれず、内部の汚れを助長することが無い。また、空気調和機の持つ室内空気の浄化作用も減殺されることが無い。また、上方に突形状の熱交換器を用いるので、跳ね上げ自在の前面パネルの内側に設けた閉鎖部材と熱交換器の前部との間が吸込まれた室内空気の流通路となり、ここを流れる気流に空気清浄フィルターを臨ませることが可能となって、空気清浄作用が惹起される。また、跳ね上げ自在の前面パネルを採用して空気調和機の保守作業を容易にしたことと、空気調和機の保守作業で最大の課題であるフィルターの清掃を自動化したことで環境への負荷を低減することができる。また、空気調和機の運転時も前面パネルが前方に開くことも無いので、室内機の内部が使用者の目に曝されることも無く、室内の雰囲気を乱さず、美観を維持し続ける。   Thereby, a part of the intake air passes through the air purification filter, allergens drifting in the airflow are removed, the room is gradually cleaned, and a comfortable space is formed. At this time, since the closing member is provided inside the front panel that can be flipped up, the intake air is sucked only from the suction port on the top surface, and the air that does not pass through the suction port from the gap between the front panel that can be flipped up and the main body Is not sucked in and does not promote internal dirt. Further, the purifying action of the indoor air that the air conditioner has is not diminished. In addition, since a projecting heat exchanger is used above, it becomes a flow path of indoor air sucked between the closing member provided inside the front panel that can be flipped up and the front part of the heat exchanger. An air purifying filter can be exposed to the flowing airflow, and an air purifying action is induced. In addition, the front panel that can be flipped up is used to facilitate the maintenance work of the air conditioner, and the cleaning of the filter, which is the biggest problem in the maintenance work of the air conditioner, is automated, thereby reducing the environmental burden. Can be reduced. Further, since the front panel does not open forward during the operation of the air conditioner, the interior of the indoor unit is not exposed to the eyes of the user, and the indoor atmosphere is not disturbed and the aesthetics are maintained.

このため、運転中も室内の雰囲気を乱すことが無く、吹出し空気の浄化度合が向上し、且つ、メンテナンスが容易になる空気調和機を提供することができる。   Therefore, it is possible to provide an air conditioner that does not disturb the indoor atmosphere during operation, improves the degree of purification of the blown air, and facilitates maintenance.

また、実施例の空気調和機は、前記収納部は前記機能部材を、該機能部材が前記熱交換器の前側部分に流入する気流を部分的に遮るごとく、収納する。   In the air conditioner according to the embodiment, the storage unit stores the functional member so that the functional member partially blocks the airflow flowing into the front portion of the heat exchanger.

これにより、機能部材で一部を遮られた気流は機能部材の前後で圧力差を生じ、この圧力差のよって、機能部材にも気流の一部が流れる。機能部材に流れた気流は、気流中に含んでいるアレルゲンが除去されたり、芳香を付加されたりして、空気質が向上して室内に吹出される。このように、機能部材に流れる気流の空気質が向上するので、室内の空気質も徐々に向上し、室内環境が快適になってゆく。   Thereby, the air flow partially blocked by the functional member generates a pressure difference before and after the functional member, and a part of the air flow also flows through the functional member due to the pressure difference. The airflow that has flowed through the functional member is removed from the allergen contained in the airflow or added with a fragrance, so that the air quality is improved and the air is blown into the room. Thus, since the air quality of the airflow flowing through the functional member is improved, the indoor air quality is gradually improved, and the indoor environment becomes comfortable.

このため、吸込み空気中のアレルゲンを効率よく除去する等、室内空気質の向上が図れる空気調和機を提供することができる。   For this reason, the air conditioner which can aim at the improvement of indoor air quality, such as removing the allergen in intake air efficiently, can be provided.
