BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art The housing of an indoor unit is composed of a main body and a front cover which is detachably attached to the main body, and an intake port for taking in indoor air is provided on the upper surface of the housing. An air outlet for discharging the heat-exchanged air into the room is formed in the lower part of the front surface. In the air passage that connects the suction port and the air outlet, for example, an inverted V-shaped heat exchanger is arranged to face the main body side and the front cover, and a blower (cross flow fan) is installed. It is located below the heat exchanger. By the way, since dew condensation water adheres to the heat exchanger during cooling operation, which may reduce the heat exchange performance, defrosting operation is executed to allow the dew condensation water to flow down. After being received by a dew receiving groove separately provided in the lower part of the heat exchanger, the water is drained through a drain pipe leading to the outside of the room.

[0003]

However, if the heat exchanger is formed in the inverted V shape as described above, it is necessary to provide dew receiving grooves for receiving the dew condensation water at two front and rear positions, depending on the structure. In such cases, narrowing the air passage, deteriorating the flow and distribution of the air passing through the heat exchanger, and causing turbulence to reduce heat exchange performance and to generate noise due to turbulence. There is a fear. Therefore, it is an object of the present invention to provide an indoor unit for an air conditioner that does not cause such a situation.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a body and a front cover detachably attached to the body, And a heat exchanger formed in an inverted V shape so as to face the main body and the front cover, respectively, in an air passage that connects a suction port formed on the upper surface of the main body and an air outlet formed on the lower front surface. , In the indoor unit of the air conditioner in which a blower is arranged at the bottom of this heat exchanger,
The inner surface of the main body receives the condensed water of the heat exchanger arranged on the main body side and integrally forms a rib that also serves as a rear tongue piece of the blower, and the tip of the rib is formed of the heat. I decided to match the inclination of the exchanger.

[0005]

With the above construction, the rib formed integrally on the inner surface of the main body can receive the dew condensation water of the heat exchanger arranged on the main body side, and the rib can prevent the rear tongue of the blower. In addition, since the tips of the ribs are formed so as to be substantially aligned with the inclination of the heat exchanger, a wide air passage can be secured and the flow and distribution of air passing through the heat exchanger can be improved. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a perspective view showing the appearance of an indoor unit,
FIG. 2 is a side sectional view showing the inside of the indoor unit.
Is composed of a main body 2 and a front cover 3 which is detachably covered with the main body 2, and a front panel 3a of the front cover 3 is pivotally supported at its upper portion to be openable and closable. Further, an inlet 4 for indoor air is provided on the upper surface of the front cover 3, and an outlet 5 is formed on the lower portion of the front surface. An air passage 6 is formed between the suction port 4 and the air outlet 5, and the air passage 6 is a detachable type that can be moved along the inner surface of the front cover 3 toward the main body 2. An air filter 7, a heat exchanger 8 divided into three parts, and a blower (cross flow fan) 9 are arranged, and the air that has undergone heat exchange by the heat exchanger 8 is sent to the air outlet 5 by the blower 9 and enters the room. The wind direction of is adjusted by the wind direction plate 10.

The suction port 4 is formed in a slit shape over almost the entire upper portion of the heat exchanger 8. The heat exchanger 8 is divided into three parts in the horizontal direction, and two adjacent parts are formed in an inverted V shape, one of which faces the main body 2 side and the other part of the front cover 3
It is placed toward the side. The blower 9 is provided in the center of the lower part of the heat exchanger 8 formed in an inverted V shape. With such an arrangement, the difference in distance between the blower 9 and each of the three divided heat exchangers is reduced, the distribution of the air passing through the heat exchanger 8 (wind speed distribution) can be improved, and the housing 1 This is because the can be miniaturized.

In the figure, 11 and 12 are dew receiving grooves for receiving the dew condensation water flowing down along the heat exchanger 8, but the dew receiving groove 11 near the front cover 3 only receives the dew condensation water. Instead, it also forms part of the wall of the air passage 6. Reference numeral 13 denotes a rib formed on the inner surface of the main body 2 so as to serve as a rear tongue piece of the blower 9 while receiving the condensed water of the heat exchanger 8 arranged on the main body 2 side, and the tip of the rib is It extends substantially parallel to the inclined surface of the exchanger 8. Therefore, there is no protrusion that disturbs the air flow, and the air passage 6 is wide.

[0009]

[Advantages of the Invention] With the rib as described above, the dew receiving groove can also serve as the rear tongue of the blower, and a protrusion that obstructs the flow of air passing through the heat exchanger can be provided. Since there is no heat exchanger, the wind speed distribution is good, and there is no fear of turbulence, so a quiet indoor unit with less noise can be obtained.
