2. Description of the Related Art A conventional air conditioner of this type is disclosed in
It was configured as shown in JP-A-2-14070. This will be briefly described with reference to FIGS. 7 and 8. In FIG. 7, reference numeral 1 denotes a main body casing formed of a steel material or the like into a substantially rectangular cylindrical shape, and a moving caster 2 is provided at the bottom thereof. The interior is divided into three layers. 3 is the base plate 4
A compressor 5, a condenser 6, a condensing-side air filter 7, and the like are placed on a base plate 4 and a drain tank housed and arranged in a lower space partitioned by the above. Other electrical components 8 and piping 9 are also accommodated. The condenser-side air filter 7 faces the rear side of the main body casing 1, and a hot air flow passage 10 that sends hot air that has passed through the air filter 7 and the condenser 6 to the rear end side of the upper space is formed in the middle space. Is formed. Note that a part of the base plate 4 that partitions the middle space is formed in a substantially shallow dish shape, and is configured so that the drain generated in the middle space can be collected in the drain tank 3.
In the figure, reference numeral 11 denotes an air guide plate provided at the upper end of the condenser 6 and separating the middle space and the upper space. Reference numeral 12 denotes a partition plate that partitions the front and rear portions of the main casing 1 into an intake-side air passage 13 and an exhaust-side air passage 14 in the upper space. The partition plate 12 inclines from the upper center to the lower rear in the upper space. At the same time, its lower end is inclined toward the lower front,
A lower end portion thereof is bent toward a lower front portion, and a cooler-side air filter 15 facing above a front portion of the main body casing 1 in front of the partition plate 12 in the upper space, A cooler 16 located behind the cooler-side air filter 15 and a drain pan located below the cooler 16
17 and a fan casing 18 mounted on the front side of the partition plate 12 behind the cooler 16. A biaxial motor 19 is disposed in the center of the rear part of the partition plate 12, and a sirocco fan 21 is connected to a front shaft 20 that penetrates through the partition plate 12 and projects forward. In the figure, reference numeral 22 denotes an air outlet duct provided at an upper portion of the main casing 1, and the air outlet duct 22 is connected to an air outlet of a passage formed by the fan casing 18 and the partition plate 12. A series of cooler-side air passages from the cooler-side air filter 15 through the cooler 16 and the sirocco fan 21 to the blow-out duct 22
13 are configured. On the other hand, a propeller fan 24 is connected to the rear shaft 23 of the double shaft motor 19, and the propeller fan
24 is a bellmouth with a concentric protective frame around it 25
And faces an exhaust hole 26 formed above a rear portion of the main body casing 1. Furthermore, this propeller fan
The rear space of the upper space in which 24 is disposed is connected to the middle space serving as the hot air flow passage 10, whereby the condenser-side air filter 7 to the condenser 6, the hot air flow passage
10, a series of exhaust-side air passages 14 extending to the exhaust holes 26 via the propeller fan 24 and the bell mouth 25 are formed.

In the air conditioner having such a configuration, when the operation switch of the electric component 8 is turned on and the double-shaft motor 19 for the blower and the compressor 5 are started, the refrigerant gas flows into the compressor 5, the condenser 6, It flows in the refrigerant circulation path connecting the cooler 16, and a known refrigeration cycle is configured. At this time, a cooling action is performed in the cooler side air passage 13 passing through the cooler 16,
Cool air is blown out from the blow-out duct 22, while heat is released from the condenser 6 in the condenser-side air passage 14, and hot air is exhausted from the exhaust holes 26.

[0004]

In the air conditioner having the above-described structure, the drain tank 3 housed and arranged in the lower space is usually made of a commercially available polytank or the like. When the drain tank 3 is covered with the front lower panel 34 to enhance the product value,
It was difficult to grasp the amount of accumulated drain, and the drain panel had to be opened each time the drain was discharged, and the workability was poor.

[0005] The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to make an air conditioner inexpensive, to make draining work easy, and to have an excellent design. And
