The control box is provided to a portion which is on the downstream side of an air flow relative to the fan case suction port and which is other than a region connecting the fan case blowout port to the opening part of the partition plate in the longitudinal direction and the horizontal direction of the housing.

Description

空気調和装置の室内機Indoor unit of air conditioner
　本発明は、空気調和装置の室内機に関し、特に、室内機のファンモータ等の制御を行なう制御部を有する制御箱の配置構造に関する。 The present invention relates to an indoor unit of an air conditioner, and more particularly to an arrangement structure of a control box having a control unit for controlling a fan motor or the like of the indoor unit.
　空気調和装置の室内機本体には、空気を吸い込むための吸込口及び空気を吹き出すための吹出口が設けられている。吸込口から吸い込まれた空気の吹出口までの風路には、制御箱及び熱交換器が設けられる。制御箱は、室内機のファンモータ等の制御を行なう制御部を有する。制御箱及び熱交換器よりも風路の下流側には、ファンを収容するファンケーシングが設けられている。 The indoor unit body of the air conditioner is provided with a suction port for sucking in air and an outlet for blowing out air. A control box and a heat exchanger are provided in the air passage from the suction port to the air outlet of the sucked air. The control box has a control unit that controls a fan motor or the like of an indoor unit. A fan casing for accommodating the fan is provided on the downstream side of the air passage from the control box and the heat exchanger.
　吸込口から吸い込まれた空気は、熱交換器と熱交換が行なわれる。熱交換器により熱交換された空気は、制御箱及び熱交換器よりも風路の下流側に設けられたファンケーシングに収容されたファンにより吹出口より吹き出される（例えば、特許文献１参照）。 The air sucked from the suction port is heat exchanged with the heat exchanger. The air heat-exchanged by the heat exchanger is blown out from the outlet by a fan housed in a fan casing provided on the downstream side of the air passage from the control box and the heat exchanger (see, for example, Patent Document 1). ..
特許第６５１６８５３号公報Japanese Patent No. 6516853
　制御箱は、ファンよりも風路の上流側に熱交換器とともに配置される。従って、制御箱は、ファンにより吸込口から吸い込まれる空気の風路の抵抗となる。空気調和装置の室内機は、風路の抵抗が増大すると、送風機の送風をその分大きくしなければならないという課題がある。 The control box is placed together with the heat exchanger on the upstream side of the air passage from the fan. Therefore, the control box becomes a resistance of the air passage of the air sucked from the suction port by the fan. The indoor unit of the air conditioner has a problem that when the resistance of the air passage increases, the air blown by the blower must be increased accordingly.
　本発明は、上記実情に鑑みてなされたものであり、制御箱の風路の抵抗を少なくすることにより、送風機の送風を小さくすることができる空気調和装置の室内機を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an indoor unit of an air conditioner capable of reducing the air blown air of a blower by reducing the resistance of the air passage of the control box. To do.

A fan case having a fan case suction port for sucking air from the suction port, a fan case outlet for blowing air sucked from the fan case suction port toward the outlet, and a fan housed in the fan case. , The air of the suction port of the housing is sucked from the fan case suction port, and the sucked air is blown from the fan case outlet to the outlet through the opening of the partition plate. It has an opening at a position corresponding to the fan, the heat exchanger housed in the housing, and the fan case outlet of the fan case, and is arranged between the fan case and the heat exchanger.

　本発明によれば、制御箱がファンケース吸込口よりも空気の流れの下流側であって、かつファンケース吹出口を仕切板の開口部に筐体の長手方向と水平方向に繋ぐ領域以外の部分に配置される。このような場所は、ファンケースの上流側よりも空気の流れは緩やかである。従って、室内機の筐体内において制御箱の風路の抵抗を、少なくすることができ、その結果、送風機の送風を小さくすることができる。 According to the present invention, the control box is on the downstream side of the air flow from the fan case suction port, and the fan case outlet is not connected to the opening of the partition plate in the longitudinal direction and the horizontal direction of the housing. Placed in the part. In such a place, the air flow is slower than that on the upstream side of the fan case. Therefore, the resistance of the air passage of the control box can be reduced in the housing of the indoor unit, and as a result, the air blown by the blower can be reduced.

Further, the control box 6 includes an air passage and a second air passage between the suction port 2 of the housing 1 and the first fan case suction port 10a of the first fan case 7a and the second fan case suction port 10b of the second fan case 7b. 1 Do not block the air passage between the fan case outlet 11a and the first opening 5a of the partition plate 5 and the air passage between the second fan case outlet 11b and the second opening 5b of the partition plate 5. As described above, it may be arranged on the upper surface side in the housing 1. The method of attaching the control box 6 to the housing 1 does not matter.
　熱交換器４は、仕切板５の第１開口部５ａ及び第２開口部５ｂを通過した空気と熱交換器４の配管（図示せず）内を流れる冷媒との熱交換を行なう。熱交換器４は、筐体１内に前後方向に対して斜めに配置される。熱交換器４を通過した空気は、筐体１の右側面に設けられた吹出口３から吹き出される。 The heat exchanger 4 exchanges heat between the air that has passed through the first opening 5a and the second opening 5b of the partition plate 5 and the refrigerant that flows in the piping (not shown) of the heat exchanger 4. The heat exchanger 4 is arranged obliquely in the front-rear direction in the housing 1. The air that has passed through the heat exchanger 4 is blown out from the air outlet 3 provided on the right side surface of the housing 1.
　実施の形態１に係る空気調和装置の室内機１００によれば、制御箱６は、筐体１の吸込口２と第１ファンケース７ａの第１ファンケース吸込口１０ａ及び第２ファンケース７ｂの第２ファンケース吸込口１０ｂとの間の風路以外の部分に配置される。さらに、制御箱６は、第１ファンケース吹出口１１ａと仕切板５の第１開口部５ａとの間の風路以外及び第２ファンケース吹出口１１ｂと仕切板５の第２開口部５ｂとの間の風路以外のファンケース空間１ａであり、かつ第１ファンケース７ａの第１ファンケース吸込口１０ａ及び第２ファンケース７ｂの第２ファンケース吸込口１０ｂよりも風路の下流側に配置される。 According to the indoor unit 100 of the air conditioner according to the first embodiment, the control box 6 is the suction port 2 of the housing 1 and the first fan case suction port 10a and the second fan case 7b of the first fan case 7a. It is arranged in a portion other than the air passage between the second fan case and the suction port 10b. Further, the control box 6 includes other than the air passage between the first fan case outlet 11a and the first opening 5a of the partition plate 5, and the second fan case outlet 11b and the second opening 5b of the partition plate 5. It is a fan case space 1a other than the air passage between the air passages, and is on the downstream side of the air passage from the first fan case suction port 10a of the first fan case 7a and the second fan case suction port 10b of the second fan case 7b. Be placed.
　制御箱６が配置される位置は、第１ファンケース７ａの第１ファンケース吸込口１０ａ及び第２ファンケース７ｂの第２ファンケース吸込口１０ｂの上流側よりも空気の流れは緩やかである。従って、室内機１００の筐体１内において制御箱６の風路の抵抗を、少なくすることができ、その結果、送風機の送風を小さくすることができる。 The position where the control box 6 is arranged is that the air flow is slower than the upstream side of the first fan case suction port 10a of the first fan case 7a and the second fan case suction port 10b of the second fan case 7b. Therefore, the resistance of the air passage of the control box 6 can be reduced in the housing 1 of the indoor unit 100, and as a result, the air blown by the blower can be reduced.
