An air outlet provided with a bell mouth 6 opposed to the turbo fan 3 at a central portion, and an air outlet 7 rotatably supporting a wind direction change plate a between the air outlet 7 and the main body case 1.
The grill 8 having the structure having the above structure is attached to the lower part of the main body case 1 so as to face the room.

[0003] However, when the wind direction changing plate a is rotated to the horizontal blowing position during the cooling operation, the cool wind blown out from the blow-out port 7 touches the ceiling surface to generate water droplets, and dust tends to adhere. However, there is a problem that mold is generated.

[0004] Further, when the wind direction change plate a is rotated to the downward blowing position during the heating operation, there is a problem that the warm air blown out from the blow-out port 7 easily rises and does not easily reach the feet. .

[0005]

SUMMARY OF THE INVENTION In view of the above problems, in the present invention, an auxiliary blow-out port is provided in which the position of the grill is swelled slightly lower and a substantially horizontal blow-out is provided above the blow-out blow-out port. A ceiling-mounted type that sends out air that has not been heat-exchanged from the outlet to prevent cold air during cooling operation from contacting the ceiling surface, while suppressing warm air from above during heating operation to make it easier to reach the feet. It is intended to provide an air conditioner.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a fan motor and a fan motor driven by the fan motor at a substantially central portion inside a top plate in a box-shaped main body case having an open lower portion. And a heat exchanger surrounding the fan motor and the turbo fan, and a heat insulating member is provided inside the main body case facing the upper part and the side part of the heat exchanger, A portion having a suction mouth formed of a bell mouth opposed to the turbo fan, and a grill having a configuration having an air outlet between the main body case and the grille attached to a lower portion of the main body case so as to face a room. In the ceiling-embedded air conditioner, an introduction portion for introducing the suction air sucked from the suction port is provided between the upper portion of the heat exchanger and the heat insulating member, and the position of the grill is slightly lower. To Out and features the outlet auxiliary outlets to be substantially Yokobuki out on top of, and has a structure in which an auxiliary air passage which is partitioned by the partition member between these inlet portions and auxiliary outlets.

[0007] The auxiliary outlet is formed so that its length in the longitudinal direction is substantially the same as the length of the outlet.

[0008] Further, the introduction portion is provided with a blower guide for guiding the suction air from the suction port smoothly.

Further, the blower guide is constituted by a guide plate formed integrally with the partition.

Further, the blower guide is constituted by a guide plate hanging down from a top plate of the main body case.

The fan 4 is a heat exchanger surrounding the fan motor 2 and the turbo fan 3, and the heat insulating member 5 is provided inside the main body case 1 facing the upper and side portions of the heat exchanger 4. , 8 are provided with a suction port composed of a bell mouth 6 facing the turbo fan 3 at the center, and an air outlet 7 rotatably supporting a wind direction changing plate a between the bell mouth 6 and the main body case 1. This is a grill mounted below the main body case 1 so as to face the room.

An inlet 9 is provided between the upper part of the heat exchanger 4 and the heat insulating member 5 for introducing the suction air sucked from the suction port, while the position of the grill 8 is slightly expanded downward. In addition, an auxiliary air outlet 10 which is a substantially horizontal air outlet is provided above the air outlet 7, and the introduction portion 9 and the auxiliary air outlet are provided.
An auxiliary ventilation passage 12 defined by a partition body 11 is formed between the auxiliary air outlets 10 and the auxiliary air outlet 12.
By allowing blow-out air that has not been heat-exchanged from 10 to be sent out, and by preventing cool air during cooling operation from contacting the ceiling surface, water droplets do not form on the ceiling surface to prevent dust from adhering, While preventing mold from being generated, the structure is such that the warm air during the heating operation is suppressed from above so as to easily reach the feet.

Further, since the length of the auxiliary outlet 10 in the longitudinal direction is substantially the same as the length of the outlet 7, the cold air in the cooling operation comes into contact with the ceiling surface as described above. It is possible to achieve the effect of preventing the air from being heated or suppressing the warm air during the heating operation from above so as to make it easier to reach the feet, thereby realizing comfortable air conditioning.

Further, the introduction portion 9 is provided with a blower guide 13 for guiding the suction air from the suction port smoothly, so that the suction air can be guided effectively.

Further, the blower guide 13 is connected to the partition 11
And a guide plate formed integrally therewith, whereby the air guide 13 and the partition
While being able to finish 11 dimensions and shapes accurately,
It becomes a structure advantageous in cost.

Further, the blower guide 13 is constituted by a guide plate hanging from the top plate 1a of the main body case 1, whereby the blower guide 13 and the top plate 1a are formed.
A gap (play) does not occur at the position, and so-called chattering noise does not occur at the location.

With the above configuration, FIGS. 1A and 1
(B), as shown in FIG. 2 and FIG. 3, an introduction portion 9 for introducing the suction air sucked from the suction port between the upper portion of the heat exchanger 4 and the heat insulating member 5. While providing
The position of the grill 8 is swelled to a slightly lower position so that the outlet 7
An auxiliary air outlet 10 which becomes a substantially horizontal air outlet is provided at the upper part of the auxiliary air outlet, and an auxiliary air passage 12 defined by a partition body 11 is formed between the introduction portion 9 and the auxiliary air outlet 10.
By allowing the blow-out air that has not been heat-exchanged to be sent out from 10 and preventing the cool air during cooling operation from contacting the ceiling surface, water droplets do not form on the ceiling surface to prevent dust from adhering, The ceiling-mounted air conditioner is designed to prevent mold from occurring, while suppressing the warm air during the heating operation from above so as to easily reach the feet.
