DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

First Embodiment FIGS. 1 to 5 show a local air conditioner according to a first embodiment of the present invention.

This local air conditioner is used to cool a local area, as called a spot air conditioner, as described in the section of the prior art, and includes a compressor 1 and a condenser 2. The evaporator 3 is disposed in a rectangular parallelepiped casing 4. Reference numeral 5 denotes a condenser fan, reference numeral 6 denotes an evaporator fan, reference numeral 7 denotes a double-axis motor serving as a drive source of both fans 5, 6, and reference numeral 8 denotes a cool air outlet. The inside of the casing 4 is partitioned by a partition plate 9 into an upper heat exchange chamber 9 and a lower drain tank storage chamber 10. In the heat exchange chamber 9, the condenser 2, the evaporator 3, A device fan 5 and an evaporator fan 6 are provided, and a compressor 1 and a drain tank 11 are provided in the drain tank storage chamber 10. Reference numeral 12 denotes a caster for moving the local air conditioner, 13 denotes a lid that opens and closes an outlet 10a of the drain tank storage room 10,
14 is a drain pan, 21 is a warm air outlet, and 31 and 32 are air inlets.

As shown in FIGS. 4 and 5, the bottom surface of the drain tank storage chamber 10 has an annular concave groove 15 on the outer periphery, and a central portion is a raised portion surrounded by the concave groove 15. 1
6. The raised portion 16 and the drain tank storage room 1
The lower end edge 17 which is the outlet 10a of 0 is set at substantially the same height.

A pair of rollers 18, 18 serving as rolling members are attached to the lower edge 17 of the drain tank accommodating chamber 10 serving as the outlet 10a at a predetermined interval. Each roller 18 is connected to the drain tank storage chamber 10.
The roller 1 is attached to a lower edge 17 serving as an outlet 10a of the roller 1 through a substantially U-shaped bracket 19.
8 has an outlet 10 of the drain tank storage chamber 10.
It is slightly higher than the lower edge 17 and the raised portion 16 as a. The rollers 18, 18 are provided in the drain tank 1
1 functions as a moving means for facilitating movement in the take-out direction. Reference numeral 20 denotes a bolt for fixing the bracket 19.

The following effects are obtained in the local air conditioner configured as described above.

During the operation of the local air conditioner, the air W sucked in by the drive of the evaporator fan 6
Is cooled in the process of passing through the evaporator 3 to become cool air W ′, and is blown out from the cool air outlet 8 toward a local part (for example, an operator). On the other hand, the air W sucked by the driving of the condenser fan 7 is heated in the process of passing through the condenser 2, becomes hot air W ″ and is blown out from the hot air outlet 21.

During the air-conditioning operation described above, the drain generated in the evaporator 3 is stored in the drain tank 11 via the drain pan 14. Then, when the drain tank 11 is full, the drain tank 11 is taken out of the drain tank storage chamber 10 and the drain is discharged. In the present embodiment, as shown in FIG. Removal direction (ie, arrow P direction)
When the drain tank 11 is pulled out, the lower curved portion 11a
The roller 1 is guided as shown by the imaginary line in FIG.
Ride on 8,18. Thereafter, the drain tank 11 is guided by the rollers 18 and 18 and is easily and smoothly taken out. In other words, the workability of taking out the drain tank 11 is greatly improved, so that the user's dissatisfaction that has existed conventionally can be eliminated, and the commercial value can be improved. Moreover, in the present embodiment, the roller 1
The rollers 8 and 18 are attached to the lower edge 17 serving as the outlet 10a of the drain tank storage chamber 10. The rollers 18 and 18 and the raised portion 16 are connected to each other when the container is not being taken out. Since the positional relationship is such that the local air conditioner cannot move on the drain 18, the drain tank 11 does not inadvertently move when the local air conditioner moves.

In this embodiment, the roller 1
Although the rollers 8 and 18 are mounted on the drain tank storage chamber 10 side, the rollers 18 and 18 may be mounted on the bottom surface of the drain tank 11 in some cases. At this time, means (for example, a stopper or the like) for preventing unnecessary movement of the drain tank 11
Must be attached.

Second Embodiment FIGS. 6 and 7 show a main part of a local air conditioner according to a second embodiment of the present invention.

In this case, a pair of ball casters 22, 22 as rolling members are provided in the concave groove 15 on the side of the outlet 10a in the drain tank storage chamber 10 in place of the rollers. In order to secure a space for arranging the ball casters 22, 22, a beveled portion 24, 24 is formed on a slope 23 connecting the concave groove 15 and the raised portion 16. Also in this case, as shown in FIG. 6, the upper surface of each ball caster 22 is slightly higher than the lower edge 17 and the raised portion 16 serving as the outlet 10a of the drain tank storage chamber 10. The ball casters 22, 22
Is to act as a moving means for facilitating the movement of the drain tank 11 in the removal direction. In this manner, when the drain tank 11 is full, the drain tank 11 is taken out of the drain tank storage chamber 10 and the drain is discharged. In the present embodiment, as shown in FIG. When the tank 11 is pulled out in the removal direction (that is, the direction of the arrow P), the drain tank 11 rides on the ball casters 22, 22 while being guided by the lower curved portion 11a as shown by the phantom line in FIG. After that, the drain tank 11 is
It is easily and smoothly taken out by being guided by 2,22. In other words, the workability of taking out the drain tank 11 is greatly improved, so that the user's dissatisfaction which has existed conventionally can be eliminated, and the commercial value can be improved.
Moreover, in the present embodiment, the ball casters 22 and 22 and the raised portions 16 are in a positional relationship such that the drain tank 11 cannot ride on the ball casters 22 and 22 except at the time of removal. It is possible to prevent the drain tank 11 from inadvertently moving when the air conditioner moves.

In the present embodiment, the ball casters 22, 22 are mounted on the drain tank storage chamber 10 side. However, the ball casters 22, 22 may be mounted on the bottom surface of the drain tank 11. At that time, it is necessary to provide a means (for example, a stopper or the like) for preventing unnecessary movement of the drain tank 11. The other configuration and operation and effect are the same as those in the first embodiment, and thus the description is omitted.

Third Embodiment FIG. 8 shows moving means in a local air conditioner according to a third embodiment of the present invention.

In this case, the moving means comprises guide rails 25, 25 provided on both sides of the drain tank storage chamber 10,
Guided by the guide rails 25, 25, the drain tank 1
1 in a take-out direction. On both sides of the drain tank table 26,
Guide rollers 27, 27,... Guided in the guide rails 25, 25 are provided. In this way, the drain tank table 26 on which the drain tank 11 is placed is guided by the guide rails 25, 25 and is easily and smoothly taken out at the time of taking out, so that the workability of taking out the drain tank 11 is improved. The other configuration and operation and effect are the same as those in the first embodiment, and thus the description is omitted.
