【発明の詳細な説明】
本発明は、一体形空気調和機の送風装置に関するもので
、室内側熱交換器の効率的活用をはかることを目的の一
つとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blower device for an integrated air conditioner, and one of its objects is to efficiently utilize an indoor heat exchanger.
従来の一体形空気調和機は、室内側送風機として多翼フ
ァンを１個用い、一体形空気調和機の前面に配置された
室内側熱交換器に対向してこの多翼ファン用のケーシン
グの吸込み口を設けていた。Conventional integrated air conditioners use one multi-blade fan as the indoor blower, and the casing for this multi-blade fan draws air in opposite to the indoor heat exchanger placed at the front of the integrated air conditioner. It had a mouth.
またこのケーシングの吸込み口は円形で室内側熱交換器
風の通過する部分の面積よりかなり小さい。Moreover, the suction port of this casing is circular and is considerably smaller in area than the area through which the air passes through the indoor heat exchanger.
したがって多翼ファンが回転すると室内側熱交換器を通
過した空気は円形の吸込み口から吸込まれていくが、こ
の時室内側熱交換器を通過する空気の速度は、吸込み口
の正面はど速く、吸込み口の正面から隔れるほど遅くな
る。このことは、室内側熱交換器の各所で通過空気の分
布むらが生じ、速度の遅い所では十分な熱交換が行なわ
れず、結果的に十分な熱交換能力が得られず、効率が低
いものであった。Therefore, when the multi-blade fan rotates, the air that has passed through the indoor heat exchanger is sucked in through the circular suction port, but at this time, the speed of the air that passes through the indoor heat exchanger is faster at the front of the suction port. , the farther it is from the front of the suction port, the slower it becomes. This means that the distribution of passing air is uneven at various locations in the indoor heat exchanger, and sufficient heat exchange is not performed in areas where the velocity is slow, resulting in insufficient heat exchange capacity and low efficiency. Met.
本発明は、上記従来の欠点を除去するものである。The present invention eliminates the above-mentioned conventional drawbacks.

られている。The outdoor ventilation system path B includes an outdoor heat exchanger 6 mounted facing the back surface 5, a motor 7 mounted so that the rotating shaft a is perpendicular to the partition wall 3, and the motor 7. An axial fan 8, a compressor 9, etc., which are attached to one end and blow air toward the outdoor heat exchanger 6, are installed. a first multi-blade fan 14 rotating inside a casing 13 having an inner heat exchanger 11 and a suction port 12 attached to the rotating shaft 7b of the motor 8 and facing the indoor heat exchanger 6;
, a second multi-blade fan 17 that rotates inside a casing 16 that is attached between the first multi-blade fan 14 at the other end of the motor 8 and the partition wall 3 and has a suction port 16 facing the partition wall; A wind tunnel section 18 is provided for guiding the air blown out from the air conditioner 16 to the outside of the integrated air conditioner 1.

とになる。On the other hand, in the indoor ventilation system, there are a first multi-blade fan 14 and a second multi-blade fan 1 attached to the other end of the motor 8.
7 rotates, the casing 1 of the first multi-blade fan 14
Air mainly flows into the suction port 12 of the second multi-blade fan 1 from the front part of the indoor heat exchanger 11.
Air mainly flows into the suction port 15 of the casing 16 of No. 7 from a portion other than the front side of the suction port 12 of the first multi-blade fan 14 of the indoor heat exchanger 11. As a result, air passes through the indoor heat exchanger 11 uniformly over the entire surface.

騒音の低減がそれぞれはかれる。Therefore, the conventional problem of reduced heat exchange capacity caused by the fact that the air velocity is high only in front of the inlet of the multi-blade fan and extremely low in other parts can be solved, and 14.17 is divided into two, the amount of work per unit is reduced, and the noise radiated through the indoor heat exchanger 11 from the multi-blade fans 14 and 17 facing the indoor heat exchanger 11 is reduced. decreases. In addition, when the two multi-blade fans 14.17 on the indoor side are rotated at the same rotation speed as the conventional one, the diameter can be made smaller, so the casing 13.16 can be made larger than the diameter. Both increase air volume and reduce noise.

などの効果を有するものである。As is clear from the above embodiments, the blowing device for an integrated air conditioner according to the present invention includes a partition wall provided within a single box body to form an indoor space and an outdoor space, and a compressor and a compressor in each space. Indoor heat exchanger, indoor blower, outdoor heat exchanger,
An integrated air conditioner is constructed by housing an outdoor blower, a motor, etc., the indoor blower and the outdoor blower are respectively attached to both shafts of the motor, and the indoor blower is mounted on both shafts of the motor in the axial direction. This indoor blower has a multi-blade suction type, with one suction port of the casing facing the indoor heat exchanger, and the other suction port of the casing facing the partition wall. By using suction, the indoor heat exchanger can be ventilated uniformly throughout the entire indoor heat exchanger, thereby increasing the efficiency of the indoor heat exchanger. Furthermore, by using two multi-blade fans as the indoor blower, the amount of work per multi-blade fan is reduced, reducing noise, and at the same time, the casing can be made larger compared to the diameter of the multi-blade fan. This has the effect of reducing the noise of the multi-blade fan and increasing the air volume.
