調和機に関する。[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention aims to improve dust collection efficiency and improve comfort by capturing dust such as dust and mold adhering to the inside of an indoor unit. Regarding air conditioners.
（従来の技術）
一般に、この種の空気調和機は室内に設置される室内機
と、室外に設置される室外機とを有し、室内機としては
第９図に示すように構成された壁掛は型のものがある。(Prior Art) Generally, this type of air conditioner has an indoor unit installed indoors and an outdoor unit installed outdoors.The indoor unit is a wall-mounted unit configured as shown in Fig. 9. There is a type.
この室内機１は前面パネル２の前面にて吸込口３と吹出
口４とを図中上下に配設し、後板本体５を所要の取付壁
に取付固定するようになっている。This indoor unit 1 has an inlet 3 and an outlet 4 disposed vertically in the figure on the front surface of a front panel 2, and a rear plate main body 5 is attached and fixed to a required mounting wall.
吸込口３と吹出口４とはファンケーシング６内の通風Ｉ
ｍ７を介して連通し、この通風路７には室内側熱交換器
８ε横流フアンよりなる室内ファン９とを前後に配設し
ている。The suction port 3 and the blowout port 4 are the ventilation I inside the fan casing 6.
In this ventilation passage 7, an indoor heat exchanger 8ε and an indoor fan 9 consisting of a cross-flow fan are arranged in front and behind each other.
室内側熱交換器８は図示しない冷媒配管によりコンプレ
ッサ、四方弁、室外側熱交換器、キャピラリチューブ等
の減圧器等に順次かつループ状に接続され、冷媒を循環
させる閉じた冷凍サイクルの一部を構成している。The indoor heat exchanger 8 is connected sequentially and in a loop to a compressor, a four-way valve, an outdoor heat exchanger, a pressure reducer such as a capillary tube, etc. through refrigerant piping (not shown), and is part of a closed refrigeration cycle that circulates the refrigerant. It consists of
前記室内ファン９はその運転時に室内等の空調空間の空
気を図中大矢印に示すように室内１１１内を通風させる
。When the indoor fan 9 is operated, the indoor fan 9 circulates air in an air-conditioned space such as a room into the room 111 as shown by the large arrow in the figure.
すなわち、室内ファン９の回転により、室内等の空調空
間の空気を吸込口３からその内方へ吸い込み、エアフィ
ルタ１０により濾過し、さらに、室内側熱交換器８にて
熱交換し、冷気あるいは暖気を吹出口４から室外等の空
調空間へ吹き出し、室内を冷房または暖房するようにな
っている。That is, as the indoor fan 9 rotates, air from an air-conditioned space such as a room is sucked inward through the suction port 3, filtered by the air filter 10, and then heat exchanged by the indoor heat exchanger 8, resulting in cool air or Warm air is blown out from the air outlet 4 to an air-conditioned space such as outdoors to cool or heat the room.
（発明が解決しようとする課題）
しかしながら、このような従来の室内ｌ１１１ではエア
フィルタ１０より下流側のファンケーシング６内で付着
した埃やカビ等の塵埃が空調運転の運転開始時に吹出口
４から室内へ放出され、室内空気を汚染する可能性があ
る。(Problem to be Solved by the Invention) However, in such a conventional indoor l111, dust such as dust and mold adhering inside the fan casing 6 on the downstream side of the air filter 10 is released from the air outlet 4 when the air conditioning operation starts. It may be released indoors and contaminate indoor air.
すなわち、近年では保健衛生の面から室内空気の浄化が
注目されており、例えば通風路７内に内蔵されるエアフ
ィルタ１０や室内ファン９の外表面に抗菌剤を練り込み
、あるいはコーティングする等の抗菌処理を施している
ものもある。That is, in recent years, purification of indoor air has been attracting attention from the viewpoint of health and hygiene. Some are even treated with antibacterial treatment.
しかし、この抗菌処理方法ではエアフィルタ１０等の表
面では抗菌剤の効果を奏するが、この外表面にカビ等が
堆積した上に、さらにその上層部に付着したカビに対し
ては抗菌効果が低減する。However, in this antibacterial treatment method, although the antibacterial agent is effective on the surface of the air filter 10, etc., the antibacterial effect is reduced when mold, etc. accumulates on this outer surface and further adheres to the upper layer. do.
また、カビや埃等の塵埃を捕捉する手段を有しないので
、これら塵埃が室内ファン９の送風により、吹出口４か
ら室内へ放出され、室内空気を汚染する可能性がある。Further, since there is no means for capturing dust such as mold and dust, there is a possibility that the dust is discharged into the room from the air outlet 4 by the air blowing from the indoor fan 9 and contaminates the indoor air.
そこで、例えば吹出口４周りにｖ１ｍ用のエアフィルタ
を設置することが考えられるが、この場合にはそのエア
フィルタが通風抵抗となり、送風の属調を著しく増大さ
せ、空調能力を悪化さ仕るという課題がある。Therefore, for example, it may be possible to install an air filter for V1m around the air outlet 4, but in this case, the air filter becomes ventilation resistance, significantly increases the air flow, and deteriorates the air conditioning capacity. There is a problem.
このような塵埃の放出量は第１０図に示すように空調運
転の開始時に多く、運転時間の経過と共に、次第に少な
くなる。As shown in FIG. 10, the amount of dust emitted is large at the start of air conditioning operation, and gradually decreases as the operating time passes.
そして、＠房負荷が小さい場合等では、室内側熱交換器
８の放熱温度を降温させるようにコンプレッサがインバ

交換器２９の温度が設定値以下に低下したときに送風戻
し手段３１Ａを作動させるようになっている。In other words, the second 1111 unit is set to II during heating operation, for example.
The air return means 31A is activated when the temperature of the indoor heat exchanger 29 falls below a set value due to a reduction in the negative load on the room or at the start of operation.
すなわら、第４図に示すように戻し風路３３の入口端を
開くように上部吹出ルーバ４１の回動角を制御する。That is, the rotation angle of the upper blow-off louver 41 is controlled so as to open the inlet end of the return air passage 33 as shown in FIG.

の回動角を制御するようになっている。On the other hand, when the temperature of the indoor heat exchanger 29 is higher than the set value, the operation of the air return means 31A is stopped by the second 1IllIIll device, and the inlet end of the return air path 33 is closed as shown in FIG. The upper blowout louver 41 is fully opened.
It is designed to control the rotation angle of.
次に第２の実施例の作用を説明する。Next, the operation of the second embodiment will be explained.
例えば室内温度の昇温等により、暖房負荷が低下すると
、図示しない室内制御器等によりインバータ駆動で能力
可変のコンプレッサ（図示せず〉の能力が低減される。For example, when the heating load decreases due to an increase in indoor temperature, the capacity of an inverter-driven compressor (not shown) whose capacity is variable is reduced by an indoor controller (not shown).
このために、室内側熱交換器２９の温度が設定値以下に
低下する場合がある。For this reason, the temperature of the indoor heat exchanger 29 may drop below the set value.
また、暖房運転立上り時にも室内側熱交換器２９の温度
が設定値以下に低下する場合がある。Furthermore, even at the start of heating operation, the temperature of the indoor heat exchanger 29 may drop below the set value.
このような室内側熱交換器２９の温度が低下したことを

る。The second control is that the temperature of the indoor heat exchanger 29 has decreased! ! ! l! ! When detected by (not shown),
This second i! As shown in FIG. 4, the 1ltIl device controls the rotation angle of the upper blowout louver 41 so as to fully open the inlet end of the return air passage 33, and also controls the rotational angle of the lower blowout louver 42 so that its axis line Control it so that it stands almost vertically.
このために、室内ファン３０からの送風は上下一対の吹
出ルーバ４１，４２により戻し風路３３側と吹出口２４
側へとほぼ２手に分流する。For this reason, the air from the indoor fan 30 is returned to the air passage 33 side and the air outlet 24 by a pair of upper and lower blow-off louvers 41 and 42.
It almost splits into two hands.
吹田口２４へ分流した送風は吹出風としてそのまま室内
へ吹き出される。The air that has been diverted to the Suita outlet 24 is blown out into the room as it is as blown air.
