Moreover, the purpose is to reduce noise.

を有するものであつた。 Conventionally, there is a floor-standing type of indoor unit, but this floor-standing type is equipped with a heat exchanger 3 facing the suction port 2 of the indoor unit 1, as shown in FIG.
The heat-exchanged air is blown out from the blow-off port 5 by the cross-flow fan 4. 6 is a seal plate provided on the upper end surface of the heat exchanger 3, and this seal plate 6 allows the air to pass through the heat exchanger 3 upwardly without passing through the heat exchanger 3 in order to increase the amount of air flowing through the heat exchanger 3. It is set up so that nothing happens. 7 is a tongue portion of the cross flow fan 4. Such a conventional cross flow fan 4, tongue part 7, and heat exchanger 3
In this configuration, in a floor-standing indoor unit that requires a certain height, there is almost no gap between the lower end of the tongue 7 and the seal plate 6,
This configuration was designed to obtain a predetermined air volume. However, even if a predetermined air volume is obtained, the noise does not reach a sufficiently satisfactory noise value, and the rated noise value has no choice but to be satisfied. Furthermore, these noises have the disadvantage of causing discomfort because they are harsh to the ears.

られている。 The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 2 and 3. Reference numeral 10 denotes a floor-standing indoor unit, which has an inlet 11 and an outlet 12 on the front side. 13 is a heat exchanger provided facing the suction port 11; 14 is a cross flow fan provided on the outlet 12 side;
15 is a tongue portion; 16 is a seal plate provided up to about half the width of the heat exchanger 13; 17 is a guide plate provided identically to this seal plate 16;
The guide plate 17 is provided along each partition plate 18 of the cross flow fan 14 and facing only a portion of the circumference of the cross flow fan 14.

である。 In the above configuration, the air flowing in from the suction port 11 is passed through the air outlet 12 by the cross flow fan 14.
The air sucked in above the suction port 11 is sucked into the cross flow fan 14 by the guide plate 17, and the flow at this time is blown out without any resistance. Furthermore, due to the guide plate 17, independent air flows are formed at intervals of the partition plates 18 of the cross flow fan 14, and are directed toward the air outlet 12.
従つて、従来の吹出風量分布は点線で示すＡ分

たＢ分布の傾向に変え得るのである。 Therefore, the conventional blowout air volume distribution tends to be A distribution shown by the dotted line, but the tongue part 15 according to the present invention
The tendency of the B distribution can be changed to the averaged one by the guide plate 17 provided below the B distribution.

有するものである。 As described above, according to the present invention, in a floor-standing indoor unit that requires a certain height as in the past, the length of the tongue is shortened, and at the same time, the suction from above the suction port is placed under the tongue. Since a guide plate was installed to draw air into the crossflow fan without resistance, the noise level decreased slightly, and the harsh sound that accompanied the noise was almost completely eliminated to a satisfactory level. Furthermore, as well as reducing the noise level, the air volume also increases, albeit slightly.
