Description

本発明は湿度に応じてファンや羽根を制御することにより、部屋の湿度上昇を防止する空気調和装置に関するものである。   The present invention relates to an air conditioner that prevents an increase in humidity in a room by controlling a fan and blades according to humidity.

従来、この種の空気調和装置は、部屋の温度と設定温度との比較によって、圧縮機の運転停止を行っている（例えば、特許文献１参照）。   Conventionally, this type of air conditioner has stopped the operation of the compressor by comparing the room temperature with the set temperature (see, for example, Patent Document 1).

図４は、特許文献１に記載された従来の空気調和装置図、図５は、従来の室内ユニット側面図を示すものである。図４に示すように、室内ユニット１と室外ユニット２で構成され、圧縮機３で流体を循環させるセパレート型空気調和装置で、図５に示すように、室内ユニット１は吸込パネル４、熱交換器５、吹出口６、ファン７、上下羽根８、モータ９から構成されている。   FIG. 4 is a diagram of a conventional air conditioner described in Patent Document 1, and FIG. 5 is a side view of a conventional indoor unit. As shown in FIG. 4, it is a separate type air conditioner that is composed of an indoor unit 1 and an outdoor unit 2 and circulates fluid with a compressor 3. As shown in FIG. 5, the indoor unit 1 includes a suction panel 4 and a heat exchange unit. It comprises a vessel 5, an air outlet 6, a fan 7, upper and lower blades 8, and a motor 9.

室内ユニット１内部には、空気をＡ方向の吸込パネル４から吸い込み、熱交換器５により吸い込んだ空気と熱交換器５中を流れる流体を熱交換し、この熱交換された空気を吹出口６からファン７によりＢ方向に排出される。そして吹出口６付近にはモータ９にてスイングする上下羽根８が取り付けられている。   Inside the indoor unit 1, air is sucked from the suction panel 4 in the A direction, the air sucked by the heat exchanger 5 and the fluid flowing in the heat exchanger 5 are heat-exchanged, and the heat-exchanged air is blown out from the air outlet 6. Is discharged in the direction B by the fan 7. In the vicinity of the air outlet 6, upper and lower blades 8 that swing by a motor 9 are attached.

冷房運転時に、室内ユニット１内部でＡ方向から吸い込まれた空気が熱交換器５中の流体で冷やされ除湿してＢ方向に吹き出される。さらに吹き出された冷風は、スイングする上下羽根８により部屋の隅々まで到達する。そして冷房運転時に、室内ユニット１が設置された部屋の空調がリモコンなどより設定された設定温度に達すると、室外ユニット２の運転が停止、即ち室外ユニット２に設置された流体を循環させる装置、圧縮機３が停止する。これは、いわゆるサーモオフ状態と呼ばれる（以下サーモオフと呼ぶ）。つまり冷房運転時において、部屋の温度が設定温度にまで冷えれば圧縮機３が停止し、設定温度より上昇すれば部屋を再度冷やすために圧縮機３が運転する。空気調和装置は、部屋の温度により設定温度のあわせるため、このような運転が繰り返されている。
特開昭５５−１４００５２号公報 During the cooling operation, the air sucked from the A direction inside the indoor unit 1 is cooled by the fluid in the heat exchanger 5, dehumidified, and blown out in the B direction. Further, the blown cold air reaches every corner of the room by the swinging upper and lower blades 8. In the cooling operation, when the air conditioning of the room in which the indoor unit 1 is installed reaches a set temperature set by a remote controller or the like, the operation of the outdoor unit 2 is stopped, that is, a device for circulating the fluid installed in the outdoor unit 2; The compressor 3 stops. This is called a so-called thermo-off state (hereinafter referred to as thermo-off). That is, during the cooling operation, the compressor 3 is stopped when the temperature of the room is cooled to the set temperature, and the compressor 3 is operated to cool the room again when the temperature is higher than the set temperature. Since the air conditioner adjusts the set temperature according to the room temperature, such an operation is repeated.
Japanese Patent Laid-Open No. 55-140052

しかしながら、前記従来の構成では、空気調和装置のサーモオフ状態においては、室外ユニットは停止するが、室内ユニットのファンは設定された回転数の状態で運転している。この時、室外ユニットの圧縮機が停止するため、室内ユニットの熱交換中では吸い込まれた空気と流体との熱交換がなくなり、この吸い込まれた空気が冷やされたり除湿されたりしない状態になる。このために吸い込まれた空気は熱交換器を通過する時に熱交換器に付着した水滴（水分）を含んだ状態になりファンにより吹き出される。このため、吹き出された水分を含んだ空気により部屋の湿度が上昇し、部屋にいる人が湿度が上昇することにより不快になるため、快適性が低下するという課題を有していた。   However, in the conventional configuration, in the thermo-off state of the air conditioner, the outdoor unit is stopped, but the fan of the indoor unit is operated at the set rotational speed. At this time, since the compressor of the outdoor unit is stopped, the heat exchange between the sucked air and the fluid is lost during the heat exchange of the indoor unit, and the sucked air is not cooled or dehumidified. For this reason, the air sucked in is in a state containing water droplets (moisture) adhering to the heat exchanger when passing through the heat exchanger and blown out by the fan. For this reason, the humidity of the room is increased by the air containing the blown moisture, and the person in the room becomes uncomfortable due to the increase of the humidity, so that there is a problem that the comfort is lowered.

本発明は、前記従来の課題を解決するもので、湿度によりファンの回転数を制御するあるいは上下羽根を閉じることにより、部屋の湿度上昇を防止して快適性を向上させる空気調和装置を提供することを目的とする。   The present invention solves the above-described conventional problems, and provides an air conditioner that improves comfort by preventing the increase in humidity of a room by controlling the number of rotations of a fan by humidity or closing upper and lower blades. For the purpose.

前記従来の課題を解決するために、本発明の空気調和装置は、室内ユニットに取り付け
られた湿度検知装置において、サーモオフ中に部屋の湿度が一定湿度以上に上昇した場合、ファンの回転数を変化させる制御である。 In order to solve the above-described conventional problems, the air conditioner of the present invention is a humidity detector attached to an indoor unit, and changes the fan speed when the room humidity rises above a certain humidity during the thermo-off. Control.

これによって、サーモオフ中において熱交換器に付着した水滴（水分）を含んだ空気が部屋に吹き出されるため湿度が大きく上昇していた場合、ファンの回転数を小さくすることにより水滴（水分）を含んだ空気の放出量を低減させることができる制御である。   As a result, air containing water droplets (moisture) adhering to the heat exchanger is blown out into the room during thermo-off, so if the humidity has increased significantly, the water droplets (moisture) can be reduced by reducing the rotational speed of the fan. This is a control that can reduce the amount of air contained.

また、本発明の空気調和装置の室内ユニットに取り付けられた湿度検知装置において、サーモオフ中に部屋の湿度が一定湿度以上に上昇した場合、スイングする上下羽根を閉じる制御である。   Moreover, in the humidity detection apparatus attached to the indoor unit of the air conditioning apparatus of the present invention, when the humidity of the room rises above a certain level during the thermo-off, the control is performed to close the swinging upper and lower blades.

これによって、サーモオフ中において熱交換器に付着した水滴（水分）を含んだ空気が部屋に吹き出されるため湿度が大きく上昇していた場合、上下羽根を閉じることにより水滴（水分）を含んだ空気の放出させないため、部屋の湿度上昇なくすことができるものである。   As a result, air containing water droplets (moisture) adhering to the heat exchanger is blown out into the room during thermo-off, so if the humidity has increased significantly, air containing water droplets (water) is closed by closing the upper and lower blades. Therefore, it is possible to eliminate the increase in humidity in the room.

本発明の空気調和装置は、サーモオフ中に部屋の湿度を上昇させることなく室温制御することができ、快適性を向上させることができる。   The air conditioner of the present invention can control the room temperature without increasing the humidity of the room during thermo-off, and can improve comfort.

第１の発明は、サーモオフ中に部屋の湿度が所定値以上の場合に、室内ユニットに取り付けられたファンの回転数を小さくすることにより、熱交換器に付着した水滴（水分）を含んだ空気の室内への放出量を低減させ、湿度の上昇を低減することができる。   In the first aspect of the present invention, air containing water droplets (moisture) attached to a heat exchanger is reduced by reducing the number of rotations of a fan attached to an indoor unit when the humidity of the room is equal to or higher than a predetermined value during thermo-off. The amount of release into the room can be reduced, and an increase in humidity can be reduced.

第２の発明は、サーモオフ中に部屋の湿度が所定値以上の場合に、室内ユニットに取り付けられたスイングする上下羽根を閉じることにより、熱交換器に付着した水滴（水分）を含んだ空気を室内に放出させないため、部屋の湿度上昇なくすことができる。   In the second invention, when the humidity of the room is higher than a predetermined value during the thermo-off, the air containing water droplets (moisture) attached to the heat exchanger is closed by closing the swinging upper and lower blades attached to the indoor unit. Since it is not released into the room, the humidity in the room can be prevented from increasing.

以下、本発明の実施の形態について、図面を参照しながら説明する。尚、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.

（実施の形態１）
図１は、本発明の第１の実施の形態における室内ユニット側面図を示すものである。 (Embodiment 1)
FIG. 1 is a side view of an indoor unit according to the first embodiment of the present invention.

図１の構成は、図５の従来の室内ユニット側面図とほぼ同じであるが、室内ユニットに湿度検出装置が備えられている。図５と同じ機能を有するものについては、同じ符号で表す。   The configuration in FIG. 1 is substantially the same as the side view of the conventional indoor unit in FIG. 5, but the indoor unit is provided with a humidity detection device. Components having the same functions as those in FIG.

室内ユニット１は、空気をＡ方向の吸込パネル４から吸い込み、熱交換器５により吸い込んだ空気と熱交換器５中を流れる流体を熱交換し、この熱交換された空気を吹出口６からファン７によりＢ方向に排出する。そして吹出口６付近にはモータ９にてスイングする上下羽根８、湿度検出装置１５が取り付けられている。   The indoor unit 1 sucks air from the A direction suction panel 4, exchanges heat between the air sucked by the heat exchanger 5 and the fluid flowing in the heat exchanger 5, and the heat-exchanged air is blown from the blower outlet 6 to the fan. 7 to discharge in the B direction. In the vicinity of the air outlet 6, an upper and lower blade 8 that swings by a motor 9 and a humidity detection device 15 are attached.

冷房運転時に、室内ユニット１内部でＡ方向から吸い込まれた空気が熱交換器５中の流体で冷やされ除湿してＢ方向に吹き出される。さらに吹き出された冷風は、スイングする上下羽根８により部屋の隅々まで到達する。そして、室内ユニット１が設置された部屋の空調がリモコンなどより設定された設定温度に達すると、室外ユニット２の運転が停止、即ち室外ユニット２に設置された流体を循環させる装置、圧縮機３が停止する。このサーモオフ状態において、湿度検知装置１５の湿度が上昇した場合に、ファン７の回転数を変
化させたり、モータ９にてスイングする上下羽根８を閉じる動作を行っている。 During the cooling operation, the air sucked from the A direction inside the indoor unit 1 is cooled by the fluid in the heat exchanger 5, dehumidified, and blown out in the B direction. Further, the blown cold air reaches every corner of the room by the swinging upper and lower blades 8. When the air conditioning in the room in which the indoor unit 1 is installed reaches a set temperature set by a remote controller or the like, the operation of the outdoor unit 2 is stopped, that is, a device that circulates the fluid installed in the outdoor unit 2, the compressor 3 Stops. In this thermo-off state, when the humidity of the humidity detector 15 increases, the rotational speed of the fan 7 is changed, or the upper and lower blades 8 that swing by the motor 9 are closed.

図２は、本発明の第１の実施の形態におけるファンモータの回転数の制御図を示すものである。   FIG. 2 is a control diagram of the rotational speed of the fan motor in the first embodiment of the present invention.

図２において、室内ユニット１に設置された湿度検出装置１５の湿度が、湿度の値に応じてファン７の回転数を変更させる制御を表している。   In FIG. 2, the humidity of the humidity detecting device 15 installed in the indoor unit 1 represents control for changing the rotational speed of the fan 7 in accordance with the humidity value.

室内ユニットがサーモオフ状態、即ち室外ユニットの圧縮機が停止して、室内ユニット内の熱交換器中の流体が循環しなくなると、室内ユニットにＡ方向から吸い込まれた空気が熱交換器を通過しても冷やされず、除湿もされず、更に熱交換器に付着した水滴（水分）を含んで湿度が上がり、湿度Ｅ以上になると、ファン回転数は、設定回転数から回転数Ｈへ、湿度Ｆ以上では回転数Ｉ、湿度Ｇ以上では回転数Ｊに変化（低下）する。ファン回転数を減ずることにより吹出口から室内へ吹出される空気量が減り、即ち熱交換器５からの水滴（水分）を含まれた空気の放出量が低減される。   When the indoor unit is in the thermo-off state, that is, when the compressor of the outdoor unit stops and the fluid in the heat exchanger in the indoor unit stops circulating, the air sucked into the indoor unit from direction A passes through the heat exchanger. Even if it is not cooled, is not dehumidified, and further increases in humidity including water droplets (moisture) adhering to the heat exchanger and becomes higher than the humidity E, the fan rotation speed is changed from the set rotation speed to the rotation speed H, the humidity F Above, the rotational speed changes to I, and above the humidity G, the rotational speed J changes (decreases). By reducing the number of fan rotations, the amount of air blown into the room from the outlet is reduced, that is, the amount of air containing water droplets (moisture) from the heat exchanger 5 is reduced.

また、図３は、本発明の第１の実施の形態における上下羽根の制御図を示すものである。   FIG. 3 shows a control diagram of the upper and lower blades in the first embodiment of the present invention.

図３において、室内ユニット１に設置された湿度検出装置１５の湿度が、所定値以上の場合にスイングする上下羽根８を閉じる場合の制御図である。   FIG. 3 is a control diagram for closing the upper and lower blades 8 that swing when the humidity of the humidity detecting device 15 installed in the indoor unit 1 is equal to or higher than a predetermined value.

湿度Ｋ以下の場合において上下羽根８の位置は設定位置であるが、サーモオフ状態で湿度Ｋ以上の場合においてスイングする上下羽根８を閉じる（停止位置にする）ことにより熱交換器５からの水滴（水分）を含まれた空気の放出がなくなる。   When the humidity is lower than K, the position of the upper and lower blades 8 is a set position. However, when the upper and lower blades 8 swing when the humidity is higher than K in the thermo-off state, the water droplets (from the heat exchanger 5) are closed (to the stop position). Emission of air containing moisture is eliminated.

以上のように、本発明にかかる空気調和装置は、サーモオフ中に部屋の湿度を上昇させることなく室温制御することができ、快適性を向上させることが可能となるので、除湿機等の用途にも適用できる。   As described above, the air conditioner according to the present invention can control the room temperature without increasing the humidity of the room during the thermo-off, and can improve the comfort, so that it can be used for a dehumidifier or the like. Is also applicable.
