After passing around (53), it flows into the downstream chamber (43) through the bell mouth (44). C At that time, the air is blown obliquely to the axial direction of the blower (51). That is, the flow of air blown out from the blower (51) is a radial flow that spreads downstream.

The air blown left or upward in FIG. 1 from the blower (51) is blown out of the casing (10) through the side outlet (23) or the upper outlet (21). On the other hand, the air blown downward from the blower (51) reverses upward, is guided by the separating plate (46), is guided upward, and flows through the blowing flow path (27). The blown air flows into the space between the back plate (11) of the casing (10) and the separation plate (46), and flows upward through this space. At this time, since there is no obstacle such as the fan motor (53) in the outlet channel (27), no noise is generated by the obstacle. In addition, since the air flows smoothly without obstacles, the amount of air blowing increases. This air merges with the air flowing directly from the blower (51) to the upper surface outlet (21) and the side outlet (23), and is blown out of the casing (10). Effects of Embodiment 1—

According to the first embodiment, since the fan motor (53) is provided on the front part (16) side in the fan low light (52), there is no obstacle in the outlet flow path (27).

Because there is nothing, it will flow smoothly. As a result, the noise generated by the fan motor (53) acting as a resistance can be eliminated, and the amount of air blown out can be increased. In addition, since the air is blown out from the upper surface of the casing (10), even when the rear side is installed in close contact with the wall of a house or the like, it is possible to prevent a short circuit from inhaling the blown air again. .

Further, since the fan motor (53) is fixed by the tube sheet (35), the fan motor (53) can be securely fixed even if the heat exchanger (30) is provided on the front side.

In addition, since the blower (51) is constituted by the mixed flow fan, the width of the blow-out passage (27) between the back plate (11) and the mixed flow fan is reduced as compared with the case of using the axial flow fan. Can be narrow. As a result, a thinner outdoor unit can be configured. Also, the intake air volume can be increased as compared with the case where a centrifugal fan is used.

In addition, since a separation plate (46) for guiding the blown air blown downward from the blower (51) is provided, the blown air is separated from the separation plate (46) and the back of the casing (10).

The air blown downward from the second blower (55) is guided by the guide plate (49) and passes through the second flow path (27b) between the flow path separation plate (48) and the partition plate (41). It flows and is blown out of the casing (10) from the outlets (21, 23, 25). That is, the air blown out of the first blower (51) and the air blown out of the second blower (55) flow through the separate flow paths (27a, 27b) without obstructing each other, and the casing ( 10) is blown out. Effect of Embodiment 2

According to the second embodiment, the two blowers (51, 55) are provided at the top and bottom, so that the amount of blown air can be increased without increasing the installation area of the outdoor unit. In addition, by providing a separation plate (46), the air blown downward from the first blower (51) can be separated from the separation plate (46) and the back plate (11) of the casing (10). It is possible to smoothly flow into the space and to flow smoothly upward. As a result, the amount of air blown from the first blower (51) can be increased. Also, the first flow path (27a) through which the air blown from the first blower (51) flows upward and the second flow through which the air blown from the second blower (55) flows, by the flow path separation plate (48) Since the path (27b) is separated from the path (27b), the air blown from both blowers (51, 55) can flow smoothly without interference. As a result, the amount of air blown out from each of the blowers (51, 55) can be increased.

Other configurations, operations, and effects are the same as those of the first embodiment.

In the first embodiment, the side surface outlet (23) of the side surface portion (15) may be omitted.

In the second embodiment, the first side outlet (23) and the second side outlet (25) of each side part (15) may be omitted.

Further, in each of the above embodiments, the fan motor ( ⁵³ ) is not limited to a configuration in which the fan motor ( ⁵³ ) is fixed to the tube plate (34, 35) of the heat exchanger (30) via the motor lamp ( ⁵ ). A structure may be adopted in which a support is erected on the bottom plate on the back side of the heat exchanger (30) and fixed to this support.

Further, in each of the above embodiments, the blower (51) may be constituted by a fan other than the mixed flow fan, for example, an axial fan. In this case, the configuration may be such that the separation plate (46) is omitted. Industrial applicability

As described above, the outdoor unit of the air conditioner according to the present invention is useful for a so-called separate type air conditioner, and is particularly suitable for increasing the air flow of the outdoor unit.
