　本発明は、電装箱および熱交換器を備えた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 provided with an electrical equipment box and a heat exchanger.
　従来の空気調和機の室内機は、例えば特許文献１に開示されているように、熱交換器、送風ファンおよび電装箱（電装ユニット）を備えている。熱交換器は吸込み口側に配置され、送風ファンは吹出し口側に配置され、電装箱は、吸込み口と熱交換器との間に配置されている。上記室内機では、送風ファンが回転することにより、吸込み口から空気を吸い込み、その空気は、熱交換器を通過した後、吹出し口から吹き出される。 The indoor unit of the conventional air conditioner is equipped with a heat exchanger, a ventilation fan, and an electrical equipment box (electrical component unit), as disclosed, for example, in Patent Document 1. The heat exchanger is disposed on the inlet side, the blower fan is disposed on the outlet side, and the electrical equipment box is disposed between the inlet and the heat exchanger. In the indoor unit, when the blower fan rotates, air is sucked from the suction port, and the air passes through the heat exchanger and is then blown out from the blowout port.

　とろこが、上記従来のように、電装箱を熱交換器の風上側に配置した構成では、電装箱が邪魔になり、熱交換器に吸込み口から吸い込んだ風が当たりに難くなる。このため、熱交換器による熱交換機能が低下するという問題点を有している。 In the configuration in which the electrical component box is disposed on the windward side of the heat exchanger as in the above-described conventional case, the electrical component box becomes an obstacle, and the air sucked into the heat exchanger from the suction port is difficult to hit. For this reason, it has the problem that the heat exchange function by a heat exchanger falls.
　したがって、本発明の一態様は、吸込み口から吸い込んだ空気を電装箱に邪魔されることなく熱交換器に当てることができる空気調和機の室内機の提供を目的としている。 Therefore, one aspect of the present invention aims to provide an indoor unit of an air conditioner that can apply the air sucked from the suction port to the heat exchanger without being disturbed by the electrical component box.
　上記の課題を解決するために、本発明の一態様に係る空気調和機の室内機は、熱交換器、吸込み口、吹出し口、送風ファンおよび電装箱を備え、前記吸込み口から吸い込んだ空気を前記熱交換器に吹き付け、前記吹出し口から吹き出す空気調和機の室内機であって、前記電装箱は前記熱交換器の風下側に配置されている。 In order to solve the above problems, an indoor unit of an air conditioner according to one aspect of the present invention includes a heat exchanger, a suction port, a blowout port, a blower fan, and an electric box, and the air sucked from the suction port is It is an indoor unit of the air conditioner which sprays to the said heat exchanger and blows off from the said blowing outlet, Comprising: The said electrically equipped box is arrange | positioned at the downwind side of the said heat exchanger.
　本発明の一態様によれば、電装箱は熱交換器の風下側に配置されているので、送風ファンによって、吸込み口から吸い込んだ空気を、電装箱に邪魔されることなく、熱交換器に吹き付けることができる。これにより、熱交換器による熱交換機能を向上することができるという効果を奏する。 According to one aspect of the present invention, since the electrical component box is disposed on the leeward side of the heat exchanger, the air can not be disturbed by the electrical component box due to the air sucked from the suction port by the blower fan. It can be sprayed. As a result, the heat exchange function of the heat exchanger can be improved.

Embodiments of the present invention will be described below based on the drawings. FIG. 1 is a perspective view showing the appearance of the indoor unit 1 of the air conditioner of the present embodiment. FIG. 2 is a longitudinal sectional view of the indoor unit 1 of the air conditioner shown in FIG.
　（室内機の構造）
　図１に示すように、空気調和機の室内機１は、室内機本体部２の前面に導風板３を備えている。室内機本体部２は、図２に示すように、上部に第１吸込み口１１を有し、下部に第２吸込み口１２を有し、内部に送風ファン１３および熱交換器１４を有し、前部に吹出し口１７を有している。室内機１は、さらに熱交換器１４の風下側の領域に電装箱１９を有している。 (Structure of indoor unit)
As shown in FIG. 1, the indoor unit 1 of the air conditioner is provided with a baffle plate 3 on the front surface of the indoor unit main body 2. As shown in FIG. 2, the indoor unit body 2 has a first suction port 11 at the top, a second suction port 12 at the bottom, and a blower fan 13 and a heat exchanger 14 inside. It has an outlet 17 at the front. The indoor unit 1 further includes an electrical equipment box 19 in the leeward side of the heat exchanger 14.
　また、室内機１は、第１吸込み口１１の内側（下側）に第１フィルタ１５を有し、第２吸込み口１２の内側（上側）に第２フィルタ１６を有している。第１フィルタ１５は、例えばプレフィルタに相当する機能を有するフィルタであり、第２フィルタ１６よりも低性能であり、第２フィルタ１６よりも通風抵抗が小さいフィルタである。第２フィルタ１６は、例えばＨＥＰＡフィルタ(High Efficiency Particulate Air Filter)であり、第１フィルタ１５よりも高性能であり、第１フィルタ１５よりも通風抵抗が大きいフィルタである。 The indoor unit 1 also has a first filter 15 on the inner side (lower side) of the first suction port 11 and a second filter 16 on the inner side (upper side) of the second suction port 12. The first filter 15 is, for example, a filter having a function equivalent to a prefilter, is a filter that has lower performance than the second filter 16, and has a smaller ventilation resistance than the second filter 16. The second filter 16 is, for example, a HEPA filter (High Efficiency Particulate Air Filter), which is a filter that has higher performance than the first filter 15 and has a larger ventilation resistance than the first filter 15.
　室内機１では、第１吸込み口１１から吸い込まれた空気は、第１フィルタ１５、送風ファン１３および熱交換器１４を経て吹出し口１７から吹き出される。また、第２吸込み口１２から吸い込まれた空気は、第２フィルタ１６、送風ファン１３および熱交換器１４を経て吹出し口１７から吹き出される。 In the indoor unit 1, the air sucked from the first suction port 11 is blown out from the blowout port 17 through the first filter 15, the blower fan 13 and the heat exchanger 14. Further, the air sucked from the second suction port 12 is blown out from the blow-off port 17 through the second filter 16, the blower fan 13 and the heat exchanger 14.
　第１吸込み口１１には、第１吸込み口１１を開閉する開閉蓋１８が設けられている。開閉蓋１８は、空調モードで運転する場合に開状態となる。また、開閉蓋１８は、空気調和機が停止状態である場合、および空気調和機が空気清浄モードで運転する場合に閉状態となる。 The first suction port 11 is provided with an open / close lid 18 for opening and closing the first suction port 11. The open / close lid 18 is opened when operating in the air conditioning mode. Further, the open / close lid 18 is closed when the air conditioner is in the stopped state and when the air conditioner is operated in the air cleaning mode.
　空調モードは空気清浄機能よりも空気調和機能を優先する場合の空気調和機の運転モードである。空気清浄モードは、これとは逆に、空気調和機能よりも空気清浄機能を優先する場合の空気調和機の運転モードである。空調モードでは、空気は主として第１吸込み口１１から吸い込まれ、第１フィルタ１５を経た後、送風ファン１３により熱交換器１４へ吹き付けられ、吹出し口１７から吹き出される。一方、空気清浄モードでは、空気は第２吸込み口１２のみから吸い込まれ、第２フィルタ１６を経た後、送風ファン１３により熱交換器１４へ吹き付けられ、吹出し口１７から吹き出される。 The air conditioning mode is an operation mode of the air conditioner in which the air conditioning function is given priority over the air cleaning function. The air purification mode is, conversely, an operation mode of the air conditioner in which the air purification function is prioritized over the air conditioning function. In the air conditioning mode, air is mainly sucked from the first suction port 11, passes through the first filter 15, and is blown to the heat exchanger 14 by the blower fan 13 and blown out from the blowout port 17. On the other hand, in the air cleaning mode, air is sucked from only the second suction port 12, passes through the second filter 16, and is blown to the heat exchanger 14 by the blower fan 13 and blown out from the blowout port 17.
　送風ファン１３は、例えばシロッコファンあるいはターボファンからなる。 The blower fan 13 is, for example, a sirocco fan or a turbo fan.
　熱交換器１４は、２個の熱交換器を上下に連結し、連結部が前方へ突出した形態（くの字形）であり、送風ファン１３の前方位置に配置されている。 The heat exchanger 14 connects the two heat exchangers up and down, and the connecting portion protrudes forward (a letter shape), and is disposed at the front position of the blower fan 13.
　電装箱１９は、図２の例では、室内機１の上部かつ前部の隅の領域に配置されている。この領域は、吹出し口１７の上の領域であり、室内機１のデッドスペースである。電装箱１９の内部には、電装基板が設けられ、その電装基板には、集積回路を含む制御回路、電源トランス、各種リレーおよび配線を接続する多数のコネクタ等が設けられている。 In the example of FIG. 2, the electrical equipment box 19 is disposed in the area of the upper and front corners of the indoor unit 1. This area is an area above the outlet 17 and is a dead space of the indoor unit 1. An electrical component board is provided inside the electrical component box 19, and the electrical component substrate is provided with a control circuit including an integrated circuit, a power supply transformer, various relays, and a large number of connectors for connecting wires.
