Description

空気調和機の室内機Indoor unit of air conditioner
　本開示は、筐体にドレンパンユニットが着脱自在に取り付けられている空気調和機の室内機に関する。 This disclosure relates to an indoor unit of an air conditioner in which a drain pan unit is detachably attached to a housing.
　従来の空気調和機の室内機には、熱交換器に発生した露を受けるドレンパンと吹出口から吹き出される空気の方向を調整する風向調整機構とがドレンパンユニットと称される１つのユニットとして組み立てられ、該ドレンパンユニットが筐体に取り付けられた室内機が知られている（例えば、特許文献１参照）。風向調整機構は、吹出口から吹き出される空気の方向を調整する風向調整板、及び該風向調整板を駆動するモータ等、室内機の運転中に動作する動作物を備えている。また、筐体にドレンパンユニットが取り付けられた状態においては、ドレンパンユニットには、モータに接続された電力供給線及び制御配線等、風向調整機構の動作物を動作させる際に必要な部材が取り付けられる。 In the indoor unit of a conventional air conditioner, a drain pan that receives the dew generated in the heat exchanger and a wind direction adjustment mechanism that adjusts the direction of the air blown out from the air outlet are assembled as one unit called a drain pan unit.

　室内機の保守及び修理等の作業が容易になるよう、ドレンパンユニットは、筐体に着脱自在に取り付けられている。すなわち、ドレンパンユニットは、室内機の保守及び修理等の作業時、筐体から取り外すことができる構成となっている。このドレンパンユニットの筐体からの取り外し時、従来の空気調和機の室内機においては、作業者は、ドレンパンユニットの動作物又は該動作物を動作させる際に必要な部材のうち、ドレンパンユニットの端部に配置されているものに指を引っ掛けてドレンパンユニットを引っ張り、ドレンパンユニットを筐体から取り外す場合があった。このため、従来の空気調和機の室内機においては、ドレンパンユニットが筐体から取り外される際、ドレンパンユニットの動作物又は該動作物を動作させる際に必要な部材に意図せぬ負荷が加わり、ドレンパンユニットの動作物のその後の動作に影響を及ぼしてしまうかもしれないという課題があった。 The drain pan unit is detachably attached to the housing so that work such as maintenance and repair of the indoor unit can be facilitated. That is, the drain pan unit is configured to be removable from the housing during work such as maintenance and repair of the indoor unit. When the drain pan unit is removed from the housing, in the indoor unit of the conventional air conditioner, the operator is the end of the drain pan unit's moving object or the member necessary for operating the moving object. In some cases, the drain pan unit was removed from the housing by hooking a finger on something arranged in the section and pulling the drain pan unit. Therefore, in the indoor unit of a conventional air conditioner, when the drain pan unit is removed from the housing, an unintended load is applied to the moving object of the drain pan unit or a member necessary for operating the moving object, and the drain pan is applied. There was the problem that it might affect the subsequent movement of the moving object of the unit.
　本開示は、上述の課題を解決するためになされたもので、ドレンパンユニットが筐体から取り外される際、ドレンパンユニットの動作物又は該動作物を動作させる際に必要な部材に意図せぬ負荷が加わることを従来よりも抑制できる空気調和機の室内機を得ることを目的とする。 The present disclosure has been made to solve the above-mentioned problems, and when the drain pan unit is removed from the housing, an unintended load is applied to the moving object of the drain pan unit or a member necessary for operating the moving object. The purpose is to obtain an indoor unit of an air conditioner that can suppress the addition more than before.

　図１２は、本実施の形態に係る空気調和機の室内機における、筐体からドレンパンユニット２０を取り外す動作を説明するための図である。なお、図１２は、紙面左側が室内機１の前面側となっている。
　筐体１０からドレンパンユニット２０を取り外す場合、まず、後部筐体１１から前部筐体１２を取り外す。図１２は、この状態を示している。その後、後部筐体１１からドレンパンユニット２０を取り外すことにより、ドレンパンユニット２０を筐体１０から取り外すことができる。本実施の形態では、図１２に円弧状の矢印で示すように、ドレンパンユニット２０を前方に移動させることにより、後部筐体１１からドレンパンユニット２０を取り外すことができる。筐体１０からドレンパンユニット２０を取り外す際、本実施の形態に室内機１においては、作業者は、ドレンパンユニット２０の両端部に設けられた指掛け部５０に指を引っ掛けてドレンパンユニット２０を引っ張ることで、ドレンパンユニット２０を筐体１０から取り外すことができる。なお、ドレンパンユニット２０を筐体１０に取り付ける場合、上記の逆の手順で、ドレンパンユニット２０が筐体１０に取り付けられる。 FIG. 12 is a diagram for explaining an operation of removing the drain pan unit 20 from the housing in the indoor unit of the air conditioner according to the present embodiment. In FIG. 12, the left side of the paper is the front side of the indoor unit 1.
When removing the drain pan unit 20 from the housing 10, first, the front housing 12 is removed from the rear housing 11. FIG. 12 shows this state. After that, the drain pan unit 20 can be removed from the housing 10 by removing the drain pan unit 20 from the rear housing 11. In the present embodiment, as shown by the arcuate arrow in FIG. 12, the drain pan unit 20 can be removed from the rear housing 11 by moving the drain pan unit 20 forward. When removing the drain pan unit 20 from the housing 10, in the indoor unit 1 according to the present embodiment, the operator hooks a finger on the finger hooks 50 provided at both ends of the drain pan unit 20 and pulls the drain pan unit 20. Then, the drain pan unit 20 can be removed from the housing 10. When the drain pan unit 20 is attached to the housing 10, the drain pan unit 20 is attached to the housing 10 in the reverse procedure of the above.
　ここで、従来の室内機と同様にドレンパンユニット２０に指掛け部５０を備えていない場合、以下のように、筐体１０からドレンパンユニット２０が取り外される場合がある。 Here, if the drain pan unit 20 is not provided with the finger hook portion 50 as in the conventional indoor unit, the drain pan unit 20 may be removed from the housing 10 as described below.
　ドレンパンユニット２０は、上下風向調整板３１、該上下風向調整板３１を駆動するモータ３２、左右風向調整板４１、及び該左右風向調整板を駆動するモータ４２等、室内機１の運転中に動作する動作物を備えている。そして、これらの動作物のうち、モータ３２及びモータ４２は、ドレンパンユニット２０の端部に配置されている。このため、ドレンパンユニット２０に指掛け部５０を備えていない場合、作業者は、筐体１０からドレンパンユニット２０を取り外すときに、モータ３２又はモータ４２に指を掛けてドレンパンユニット２０を引っ張る場合がある。したがって、ドレンパンユニット２０に指掛け部５０を備えていない場合、筐体１０からドレンパンユニット２０が取り外される際に、モータ３２又はモータ４２に意図せぬ負荷が加わる場合がある。 The drain pan unit 20 operates during operation of the indoor unit 1, such as the vertical wind direction adjusting plate 31, the motor 32 for driving the vertical wind direction adjusting plate 31, the left and right wind direction adjusting plate 41, and the motor 42 for driving the left and right wind direction adjusting plate. It is equipped with a moving object. Among these moving objects, the motor 32 and the motor 42 are arranged at the end of the drain pan unit 20. Therefore, when the drain pan unit 20 is not provided with the finger hook portion 50, the operator may put a finger on the motor 32 or the motor 42 to pull the drain pan unit 20 when removing the drain pan unit 20 from the housing 10. .. Therefore, when the drain pan unit 20 is not provided with the finger hook portion 50, an unintended load may be applied to the motor 32 or the motor 42 when the drain pan unit 20 is removed from the housing 10.
　また、筐体１０にドレンパンユニット２０が取り付けられている状態においては、ドレンパンユニット２０には、モータ３２に接続された電力供給線、モータ３２に接続された制御配線、モータ４２に接続された電力供給線、モータ４２に接続された制御配線等、風向調整機構の動作物を動作させる際に必要な部材が取り付けられている。このため、ドレンパンユニット２０に指掛け部５０を備えていない場合、作業者は、筐体１０からドレンパンユニット２０を取り外すときに、これらの部材に指を掛けてドレンパンユニット２０を引っ張る場合がある。したがって、ドレンパンユニット２０に指掛け部５０を備えていない場合、筐体１０からドレンパンユニット２０が取り外される際に、これらの部材に意図せぬ負荷が加わる場合がある。 Further, in the state where the drain pan unit 20 is attached to the housing 10, the drain pan unit 20 has a power supply line connected to the motor 32, a control wiring connected to the motor 32, and a power connected to the motor 42. Members necessary for operating the moving object of the wind direction adjusting mechanism, such as the supply line and the control wiring connected to the motor 42, are attached. Therefore, when the drain pan unit 20 is not provided with the finger hook portion 50, the operator may put a finger on these members and pull the drain pan unit 20 when removing the drain pan unit 20 from the housing 10. Therefore, when the drain pan unit 20 is not provided with the finger hook portion 50, an unintended load may be applied to these members when the drain pan unit 20 is removed from the housing 10.
　したがって、ドレンパンユニット２０に指掛け部５０を備えていない場合、筐体１０からドレンパンユニット２０が取り外され、筐体１０にドレンパンユニット２０が再度取り付けられた後、上述の動作物の動作に影響を及ぼしてしまうことが懸念される。 Therefore, when the drain pan unit 20 is not provided with the finger hook portion 50, the drain pan unit 20 is removed from the housing 10 and the drain pan unit 20 is reattached to the housing 10, which affects the operation of the above-mentioned moving object. There is a concern that it will end up.
　一方、ドレンパンユニット２０に指掛け部５０を備えることにより、上述のように、作業者は、ドレンパンユニット２０の両端部に設けられた指掛け部５０に指を引っ掛けてドレンパンユニット２０を引っ張ることで、ドレンパンユニット２０を筐体１０から取り外すことができる。このため、本実施の形態に係る室内機１は、ドレンパンユニット２０が筐体１０から取り外される際、ドレンパンユニット２０の動作物又は該動作物を動作させる際に必要な部材に意図せぬ負荷が加わることを従来よりも抑制できる。 On the other hand, by providing the drain pan unit 20 with the finger hooks 50, as described above, the operator hooks his fingers on the finger hooks 50 provided at both ends of the drain pan unit 20 and pulls the drain pan unit 20 to pull the drain pan. The unit 20 can be removed from the housing 10. Therefore, in the indoor unit 1 according to the present embodiment, when the drain pan unit 20 is removed from the housing 10, an unintended load is applied to the moving object of the drain pan unit 20 or a member necessary for operating the moving object. It is possible to suppress the addition more than before.
　なお、本実施の形態では、ドレンパンユニット２０の両端部に指掛け部５０を設けたが、指掛け部５０は、ドレンパンユニット２０の少なくとも一方の端部に設けられていればよい。ドレンパンユニット２０の少なくとも一方の端部に指掛け部５０が設けられていれば、ドレンパンユニット２０の動作物又は該動作物を動作させる際に必要な部材に意図せぬ負荷が加わることを従来よりも抑制できる。この際、ドレンパンユニット２０の動作物又は該動作物を動作させる際に必要な部材のうち、ドレンパンユニット２０の端部に配置されるものは、指掛け部５０が設けられている側の端部に配置されるのが好ましい。 In the present embodiment, the finger hooks 50 are provided at both ends of the drain pan unit 20, but the finger hooks 50 may be provided at at least one end of the drain pan unit 20. If the finger hook 50 is provided at at least one end of the drain pan unit 20, an unintended load is applied to the moving object of the drain pan unit 20 or a member necessary for operating the moving object, as compared with the conventional case. Can be suppressed. At this time, among the moving objects of the drain pan unit 20 or the members necessary for operating the moving objects, those arranged at the end of the drain pan unit 20 are located at the end on the side where the finger hook 50 is provided. It is preferable to be arranged.
　また、本実施の形態ではドレンパン２１に指掛け部５０を設けたが、意図せぬ負荷が加わった際にドレンパンユニット２０の動作物に影響がない部品であれば、指掛け部５０が設けられる部品はドレンパン２１に限定されない。 Further, in the present embodiment, the finger hook portion 50 is provided on the drain pan 21, but if the component does not affect the moving object of the drain pan unit 20 when an unintended load is applied, the component on which the finger hook portion 50 is provided is a component. It is not limited to the drain pan 21.
　ここで、本実施の形態においては、上述のように、指掛け部５０は、筐体１０にドレンパンユニット２０が取り付けられた状態では、風路１５の外部に配置されている。風路１５内を流れる空気の温度と室内空気の温度との差が大きい場合、指掛け部５０が風路１５内に配置されていると、指掛け部５０に露が発生する可能性がある。このような場合、室内機１からの露だれが懸念される。しかしながら、指掛け部５０を風路１５の外部に配置することにより、このような露だれを防止することができる。 Here, in the present embodiment, as described above, the finger hook portion 50 is arranged outside the air passage 15 in a state where the drain pan unit 20 is attached to the housing 10. When the difference between the temperature of the air flowing in the air passage 15 and the temperature of the indoor air is large, if the finger hook portion 50 is arranged in the air passage 15, dew may be generated on the finger hook portion 50. In such a case, there is a concern about dew dripping from the indoor unit 1. However, by arranging the finger hook portion 50 outside the air passage 15, such dew dripping can be prevented.
　また、本実施の形態においては、図１２に示すように、筐体１０にドレンパンユニット２０が取り付けられた状態においては、指掛け部５０の背面と筐体１０との間に、指が挿入される空間５１が形成されている。このため、ドレンパンユニット２０を筐体１０から取り外す際、この空間５１に作業者が指を入れることにより、作業者が指掛け部５０に指を掛けることが容易となる。 Further, in the present embodiment, as shown in FIG. 12, when the drain pan unit 20 is attached to the housing 10, a finger is inserted between the back surface of the finger hook portion 50 and the housing 10. The space 51 is formed. Therefore, when the drain pan unit 20 is removed from the housing 10, the operator puts his / her finger in this space 51, so that the operator can easily put his / her finger on the finger hook portion 50.
　なお、ラベル等、指掛け部５０を指し示す構成を備えていると更によい。作業者が指掛け部５０を見つけやすくなるからである。 It is even better to have a configuration such as a label that points to the finger hook 50. This is because it becomes easier for the operator to find the finger hook portion 50.
　また、本実施の形態においては、指掛け部５０は、風向調整機構のモータが取り付けられている支持板２２に、指掛け部５０が設けられている。モータは強固に見えるため、ドレンパンユニット２０を筐体１０から取り外す際、最も指が掛けられやすい。風向調整機構のモータが取り付けられている支持板２２に指掛け部５０を設けることにより、風向調整機構のモータの周辺に指掛け部５０を配置できるので、該モータに指を掛けそうになった作業者が指掛け部５０を見つけることが容易となり、該モータに指が掛けられることをより抑制できる。 Further, in the present embodiment, the finger hook portion 50 is provided with the finger hook portion 50 on the support plate 22 to which the motor of the wind direction adjusting mechanism is attached. Since the motor looks strong, it is easiest to put a finger on it when removing the drain pan unit 20 from the housing 10. By providing the finger hook 50 on the support plate 22 to which the motor of the wind direction adjustment mechanism is attached, the finger hook 50 can be arranged around the motor of the wind direction adjustment mechanism, so that the operator who is about to put his finger on the motor can be placed. It becomes easier to find the finger hook portion 50, and it is possible to further suppress the finger from being hooked on the motor.
