The front-side heat exchanger 2 and the rear-side heat exchanger 3 are arranged in an inverted V-shape, and are provided in the indoor unit casing 1. The indoor unit casing 1 has a top panel 12
A top surface suction port 7 is formed on the front panel 11, and a front surface suction port 6 is formed on the front panel 11. Among them, the top surface suction port 7 is formed in substantially the entire surface of the top panel 12 in a lattice shape as in the conventional example. On the other hand, the front suction port 6 is provided at a slightly upper portion of the center of the front panel 11 so as to extend upward and extend in a lateral direction (a direction perpendicular to the drawing). An airflow guide 13 is formed on the front panel 11 above the front suction port 6 so as to be smoothly inclined downward toward the inside of the indoor unit casing 1 and reach the front suction port 6. A cross flow fan 4 is provided inside the inverted V-shape of the indoor heat exchanger.

ができる。In the air conditioner of the first embodiment, the front suction port 6 is connected to the front panel 11 constituting the indoor unit casing 1.
Is provided only in a part of. Therefore, the amount of air sucked from the front suction port 6 and flowing through the front heat exchanger 2 (that is, the amount of air flowing from the front suction port 6 to the rear side of the indoor unit casing 1 as in the related art) is reduced, and the front face is reduced. The static pressure generated between the upstream side (front suction port 6 side) of the side heat exchanger 2 and the downstream side (cross flow fan 4 side) is generated upstream of the rear side heat exchanger 3 (top surface suction port 7 side). ) And the downstream (crossflow fan 4 side).
Therefore, as shown by the broken line in FIG. 1, the room air sucked from the front inlet 6 along the airflow guide 13 passes from the center to the lower part of the front heat exchanger 2,
The room air sucked from the top surface suction port 7 passes from the upper part to the center part of the front heat exchanger 2 and passes through the rear heat exchanger 3. That is, the indoor air sucked from the front suction port 6 and the top suction port 7 forms an airflow such that the air passes evenly through each part of the indoor heat exchanger. Therefore, in the cross flow fan 4, uniform suction is performed from around the suction side, and as a result, the airflow passing through the front heat exchanger 2 and the airflow passing through the rear heat exchanger 3 are separated. Does not interfere with each other and forms an airflow that smoothly flows from the inlets 6 and 7 to the outlet 8, thereby improving the blowing performance.

For this reason, it is possible to prevent the formation of an airflow that passes straight through the shortest distance from the front suction port 6 and passes through the front heat exchanger 2. Thereby, the flow resistance to the airflow from the front inlet 6 to the front heat exchanger 2 is increased, and the static pressure formed between both sides of the front heat exchanger 2 can be reliably increased.

A front suction port 6 is partially provided at the upper part of the first suction port 1.
Therefore, unlike the conventional case, a lattice-shaped front suction port is not formed on almost the entire surface of the front panel 11, and the design of the indoor unit casing 1 can be improved. In addition, since the opening of the front suction port 6 is directed upward, the interior of the opening is not visible to the user, and the design can be further improved.

FIG. 2 is a cross-sectional view illustrating a modification of the air conditioner of the first embodiment. This air conditioner differs from the above in that the front suction port 6 is provided below the front panel 11. An opening of the front suction port 6 is formed to face downward, and a front panel 11 below the front suction port 6 is formed.
The airflow guide 13 that is smoothly inclined upward toward the inside of the indoor unit casing 1 and reaches the front suction port 6

を向上させることができる。Also in the air conditioner of this modified example, the amount of air sucked from the front suction port 6 and flowing through the front heat exchanger 2 is reduced in the same manner as described above. The static pressure generated between the downstream side heat exchanger 3 and the downstream side becomes larger than the static pressure generated between the upstream side and the downstream side of the backside heat exchanger 3. Therefore, the indoor air sucked from the front suction port 6 and the top suction port 7 forms an airflow that passes evenly through each part of the indoor heat exchanger, whereby the air flows from the suction ports 6 and 7 to the outlet 8. It is possible to form a smooth flowing airflow to improve the blowing performance. In addition, since the front suction port 6 is opened downward, it is possible to prevent the formation of an airflow that travels straight from the front suction port 6 a shortest distance and reaches the front heat exchanger 2, thereby preventing front heat exchange. The static pressure on both sides of the vessel 2 can be reliably increased. In addition, since the lattice-shaped front suction port is not formed on almost the entire surface of the front panel 11 unlike the conventional case, the design of the indoor unit casing 1 can be improved also in this case.

In this air conditioner, a front suction port 6 similar to the modification of the first embodiment described with reference to FIG. 2 is formed. The air conditioner of the second embodiment is different from the above-described modified example in that an auxiliary heat exchanger 14 is provided on the front half of the front heat exchanger 2 in the air flow direction. Since the auxiliary heat exchangers 14 are overlapped in this manner, the flow resistance against the airflow passing through the upper half of the front heat exchanger 2 is increased, and the upstream and downstream of the upper half of the front heat exchanger 2 are increased. The static pressure generated between the upstream side and the downstream side of the rear heat exchanger 3 can be made larger than the static pressure generated between the upstream side and the downstream side of the rear heat exchanger 3. Therefore, a contraction as in the conventional example is prevented from occurring in the upper portion S of the inverted V-shape of the indoor heat exchanger, and an airflow smoothly flowing from the suction ports 6 and 7 to the outlet 8 is formed. The blowing performance can be improved. By providing the auxiliary heat exchanger 14, the static pressure generated between the upstream side and the downstream side of the front side heat exchanger 2 is increased, so that the air blowing performance is improved and the heat exchange efficiency is improved. be able to.
