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 in the upper part 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 connecting the suction port and the air outlet, for example, heat exchangers formed in an inverted V shape are arranged so as to face the main body side and the front cover, respectively, and the heat exchange of the inverted V shape is performed. A blower (cross flow fan) is placed at the bottom of the unit. By the way, since dew condensation water adheres to the heat exchanger during cooling operation and may deteriorate the heat exchange performance, defrosting operation or the like is performed to allow the dew condensation water to flow down. Water is received by a dew receiving groove separately provided in the lower part of the heat exchanger, then flows down in a complicated path, and 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. Further, if there are two dew receiving grooves in the front and rear, the path from these dew receiving grooves to the joint portion of the drain pipe leading to the outside becomes complicated. Then, water leakage is likely to occur, and a die for molding the main body, the front cover, and the like becomes complicated, which causes a cost increase. Therefore, it is an object of the present invention to provide an indoor unit for an air conditioner that solves these problems.

[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 under the heat exchanger,
A dew receiving groove for receiving dew condensation water of the heat exchanger arranged on the body side is integrally formed on the inner surface side of the main body, and the dew condensation water flowing down to the dew receiving groove flows down on the back side to the outside of the main body. A drainage outlet was provided to allow it.

[0005]

With the above construction, the dew receiving groove formed integrally on the inner surface of the main body can receive the condensed water of the heat exchanger arranged on the main body side, and the condensed water flowing down into the dew receiving groove can be prevented. It can be made to flow out of the main body from a drain port formed on the back side of the main body.

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. In addition, a suction port 4 for indoor air is provided in the upper part of the front cover 3, and an air outlet 5 is formed in the lower part of the front face. 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 portion of the rib 13 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.

By the way, the dew condensation water flowing down into the dew receiving groove 12 must be discharged to the outside of the room, and the route thereof will be described below. FIG. 3 shows an essential part of the main body 2 having the dew receiving groove 12 from obliquely rearward. In the main body 2, in addition to the side wall (side surface) 14 of the air passage 6, the side wall 14
A drainage groove 15 and the like along with are integrally formed. A drain port 16 is provided on the rear side of the rear of the dew receiving groove 12 for allowing the condensed water from the heat exchanger 8 that has flowed into the dew receiving groove to flow down to the outside of the main body 2.

A mold is devised so that the drainage port 16 can be formed at the same time when the main body 2 is molded. If such a drain port 16 is provided, the dew condensation water from the dew receiving groove 12 flows down along the back surface of the main body 2 as shown by the arrow, is caught by the drain groove 15, and then flows toward the front surface. The dew condensation water flowing through the drainage groove 15 merges with the dew condensation water on the dew receiving groove 11 side provided on the front surface side, and then is drained to the outside by a separately provided drainage pipe (not shown). Has become. Incidentally, the drainage port 16 may be provided at a plurality of locations side by side,
Further, the shape is not limited to that shown in the drawing.

[0011]

As described above, in the case of the indoor unit as described above, the rib provided on the inner surface of the main body can serve as the dew receiving groove at the rear part and the rear tongue piece of the blower, and the heat exchanger can be used. Since there is no protrusion that obstructs the flow of passing air, the wind speed distribution of the heat exchanger is good, and there is no risk of turbulence, so a quiet indoor unit with less noise can be obtained, and it also flows into the dew receiving groove at the rear. Since the condensed water from the heat exchanger can be made to flow down without passing through a complicated drainage channel, no water leakage will occur.
