A compressor (not shown) is provided.

The other space of the machine room 23 defined by the partition plate is open on the front surface 5a side of the main body case 5, and a drainage tank 24 for storing dew water generated in the evaporator 20 is provided with the front cover 11. The main body case 5 is housed so as to be detachable from the front surface 5a side.

The drainage tank 24 is formed in a box shape with an open top, and projects from the front surface 5 a of the main body case 5 in a state of being housed in the main body case 5.
A hand-held recess 25 is formed below the projected front surface 24a of the drainage tank 24.
The drain tank 24 can be pulled out forward by putting a finger on 5. Further, a support portion 26 extending substantially horizontally from the front surface 24a side is formed at an upper portion on the front surface 24a side in the drainage tank 24 between both side surfaces 24b adjacent to the front surface 24a.

Numeral 27 designates a float portion having a pivot shaft 28 pivotally supported on both sides 24b of the drainage tank 24.

And two arms 35 connecting the handle 34 and the handle 34, and the handle 34 is formed in substantially the same shape over the entire front surface 24 a side of the drainage tank 24.

The handle 32 can be turned upside down by pivotally supporting the pivot shaft 33 to the drainage tank 24, and is tilted toward the front surface 24 a of the drainage tank 24, that is, the handle portion 34 is located on the front side 24 a of the drainage tank 24. The lower part of the handle part 34 of the handle 32 slidably contacts the front surface 24 a of the drainage tank 24 while being supported by the support part 26 formed at the upper part, and the handle part 34.
The upper portion 34a is formed so as to have substantially the same height as the upper end portion 24c on the front surface 24a side of the drainage tank 24.

The handle 32 is supported by the support 26 with the center of the pivot 33 located below the lower end 34b of the handle 34.

When the filter 19 is cleaned or replaced in the main body having the above structure, as shown in FIG. 4, the front cover 11 is rotated about the lower rotation engaging portion 13,
After the locking part 14 on the upper part of the front cover 11 is removed from the locked part 9 of the main body case 5, the locking part 14 is removed from the main body case 5. After the filter 19 has been cleaned or replaced, the rotating engagement portion 13 is engaged with the engaged portion 10 of the main body case 5, and the front cover 11 is rotated about the rotation engaging portion 13. Then, the locking portion 14 is locked to the locked portion 9 of the main body case 5 and the front cover 11 is attached, and the operation is completed.

At this time, on the front surface 24a side of the drainage tank 24, the upper portion 34a of the handle portion 34 of the handle 32 is located at substantially the same height as the upper end portion 24c on the front surface 24a side of the drainage tank 24. When the front cover 11 rotates, the lower part of the front cover 11 is supported on the upper surface of the handle 34 of the handle 32. Therefore, the front cover 11 can be prevented from entering the drain tank 24.

When the front cover 11 rotates, the lower portion of the front cover 11 tends to push the handle 32 downward.
Since the center of the pivot shaft 33 of the handle 32 is pivotally supported below the lower end of the handle portion 34 of the handle 32, at this time, the handle portion 3
4 tries to move diagonally forward and not downward,
A force acts on the support portion 26 and the front surface 24a of the drainage tank 24.
Thus, the force acting on the handle 32 can be received not only on the support portion 26 but also on the front surface 24a side of the drainage tank 24, and the force applied to the support portion 26 can be reduced. Therefore, it is possible to prevent the support portion 26 from being damaged.

The support portion 26 is located at a position where a force to push down the handle 32 when the front cover 11 is rotated, that is, at a position below the position where the lower portion of the front cover 11 hits the handle 32, holds the handle 32. Because of the support, the force for supporting the handle 32, which is the reaction force of the force for pushing the handle 32 downward, acts on the handle 32 in opposition to the force for pushing the handle 32 downward. . Then, handle 32
Even when a force is applied to push down the handle, a moment for rotating the handle 32 about the support portion 26 can be prevented from being generated. Accordingly, a reaction force is generated on the pivot shaft 33 against the moment of rotating the handle around the support portion 26, and it is possible to prevent a load from being applied to the pivot shaft 33 due to the reaction force. 33 can be prevented from being damaged.

When the front cover 11 is rotated, the lower part of the front cover 11 is rotated so as to slide on the upper surface of the handle portion 34 of the handle 32. The handle 32 is formed of a low friction material. Therefore, the frictional resistance at this time decreases. Therefore, the front cover 11 can be smoothly attached and detached.

Next, the operation of the main body 1 configured as described above will be described.

When the switch SW on the operation unit 6 is turned on, the operation starts, and the refrigerant is evaporated by the driving of the compressor.
The refrigerant circulates through a refrigerant circulation path returning to the compressor via the condenser 21 and the like, and the evaporator 20 performs a heat absorbing operation and the condenser 21 performs a heat releasing operation. At the same time, the air in the room is taken into the main body 1 from the air inlet 12 on the front surface 5a side of the main body case 5 by driving the blower 18. Then, after the dust is removed by the filter 19, it is cooled and dehumidified when passing through the evaporator 20. After the dehumidified cold air is heated by the condenser 21, it is returned to the room through the exhaust port 7.

By the way, the water removed from the indoor air by passing through the evaporator 20 becomes condensed water and falls on the partition plate 15, and from a drain pipe 15 a formed at the bottom of the partition plate 15 to a drain tank 24. Stored inside.

Then, when the float 29 of the float portion 27 is pushed up by the dew water in the drainage tank 24, the magnet 30 of the float portion 27 moves downward in a direction away from the full water detection sensor. Until the full water detection sensor cannot detect the magnetic field of the magnet 30, the magnet 30
Is moved by the control unit, the full state is detected, the operation is stopped, and a dehumidified water drainage request indicator (not shown) provided in the operation unit 6 is turned on.

The user sees the lighting of the dehumidification water drainage request indicator and grasps the handle recess 25 of the drainage tank 24 to hold the main body 1.
The drain tank 24 is taken out from the inside. At this time, even if the surface of the condensed water in the drainage tank 24 undulates,
On the front surface 24a side of the drain tank 24, a support portion 26 for supporting the handle 32 has a front surface 24a and both side surfaces 24 of the drain tank 24.
The support portion 26 prevents the dew condensation water from spilling from the front surface 24a side of the drainage tank 24.

Then, the conveyer carries the handle 32 and discards the dew condensation water in the drainage tank 24. After the water in the drain tank 24 is discarded, the drain tank 24 is mounted in the main body 1 again. As a result, the full water state is canceled, and the dehumidifying operation is started again.

In the above embodiment, the humidifying section 1b
Although the air conditioner including the dehumidifying unit 1a and the dehumidifying unit 1a has been described, the air conditioner is not limited to the air conditioner. I just need.

As in the above embodiment, the other end of the handle 32 is preferably formed over the entire front surface 24a of the drainage tank 24, but may be provided only on a part.

The front cover 11 and the drainage tank 24 are detachable from the front face 5a side of the main body case 5, but it is sufficient that the front cover 11 and the drainage tank 24 can be attached and detached from the same direction. The case 5 may be detached from the rear side.

The supporting portion 26 is provided on the front surface 2 of the drain tank 24.
It is desirable that the handle 4a and the front side 24a be formed over the entire side surfaces of the drainage tank 24, but it may be partially provided on the front side 24a side of the drainage tank 24 to support the handle portion 34 of the handle 32. .

Further, it is preferable to form a support portion 26 for supporting the handle 32 in a state of being tilted on the front surface 24a side of the drainage tank 24 as in the above embodiment, but as shown in FIG. A projection 33a is provided on the pivot shaft 33, and a support portion 41 that comes into contact with the periphery of the hole 40 that pivotally supports the pivot shaft 33 in a state where the handle 32 is tilted is projected outward from the side surface of the drainage tank 24, The handle 32 may be positioned in the same state as in the above-described embodiment with the handle 32 down.
