Hereinafter, embodiments of the present invention will be described in detail as examples based on the accompanying drawings.
FIG. 1 is a sectional view showing an air conditioner according to the present invention, and FIG. 2 is a perspective view showing the inside of a main body. FIG. 3 is a perspective view of the main part, and FIG. 4 is a perspective view of the main part showing a lower panel described later.
First, an outline of the air conditioner of the present application will be described. As shown in FIG. 1, an air conditioner according to the present invention has a main body configured by mounting a vertically divided lower panel 1 and upper panel 2 on a front surface of a base mounted on a wall surface. A suction port 3 is formed from a front end of an upper surface of the main body to a rear part of the upper surface, and an outlet 4 provided with a plurality of wind direction deflecting plates 4a is formed in a central portion of the lower surface. In the air passage connecting the upper and lower parts, a vertical part 5a and a rear inclined part 5b formed by bending the upper end of the vertical part 5a to be inclined rearward, and bending the upper end of the rear inclined part 5b to be inclined forward. A heat exchanger 5 comprising a front inclined portion 5c is provided, and a blower fan 6 for sending air heat exchanged by the heat exchanger 5 into a room is provided downstream thereof.
[0012]
FIG. 2 is a perspective view showing a state in which the upper panel 2 is removed from the main body. The central portion includes the above-described vertical portion 5a, rear inclined portion 5b, and front inclined portion 5c, and has a number of fins arranged side by side and a meandering shape perpendicular to the fins. The heat exchanger 5 constituted by a heat transfer tube connected by a U-shaped tube is supported by a support member projecting from a base.
[0013]
On the upper right side of the heat exchanger 5, there is provided an electrical component box 7 containing a plurality of control boards on which electronic components such as ICs are mounted, and a display element such as an LED is provided below the electrical component box 7. A display unit 8 connected to the electrical component box 7 by wiring is provided. On the left side of the heat exchanger 5, a drain pump 9 and a bracket 10 that suspends the drain pump 9 and that includes a first bracket 10a and a second bracket 10b are provided.
[0014]
As shown in the perspective view of the main part of FIG. 3, a drain pan 1a is formed on the bottom surface of the lower panel 1 for receiving the condensed water dropped from the heat exchanger 5 and storing the same. A sub-drain pan 1b extends downward from the drain pan 1a by a partition wall 1c having a communication hole. On the right rear side of the lower panel 1, a support fitting 12 formed of a sheet metal formed in an L shape and having a pipe insertion hole 12a formed therein is erected, and the support fitting 12 is formed in an L-shaped cross section, The first bracket 10a, which has a cylindrical nozzle 11 protruding from the upper front surface and supports an annular vibration isolator 10c made of rubber material, is supported at the lower portion. The second bracket 10b is formed to have a U-shaped cross section, and a hole formed in the upper surface is fitted to a lower portion of the vibration isolating member 10c mounted on the first bracket 10a, and a hole formed in the lower surface. , A cylindrical portion protruding from the upper part of the drain pump 9 is fitted. As a result, the drain pump 9 is freely supported by the first bracket 10a, so that the vibration generated from the drain pump 9 is transmitted to the support fitting 12 or the lower panel 1 as much as possible. To prevent it. A discharge port 9 a is provided on the front surface of the drain pump 9, and the discharge port 9 a and the nozzle 11 are connected by a discharge hose 13.
[0015]
As shown in FIG. 4, the sub-drain pan 1b is partitioned by a partition wall 1c having a communication hole 1d formed at a lower end thereof and communicates with the drain pan 1a. The bottom surface of the sub-drain pan 1b is the bottom surface of the drain pan 1a. It is formed to be lower. Thereby, the condensed water dropped from the heat exchanger 5 to the drain pan 1a smoothly flows into the sub drain pan 1b through the communication hole 1d and is stored.
[0016]
The condensed water stored in the sub-drain pan 1b is sucked into the drain pump 9 by a suction port provided on the lower surface of the drain pump 9, is discharged from the discharge port 9a, and is connected to the discharge port 9a. Through the discharge hose 13 and the nozzle 11, the water is discharged to the outside by an external pipe connected to the nozzle 11.
[0017]
As described above, the drain pump 9 for discharging the condensed water to the outside is provided on the left side of the heat exchanger 5, and the electrical component box 7 containing the control board is provided on the right side of the heat exchanger 5.
