And a ridge extending from the cover toward the bottom surface of the drainage tank.

[0006] A second means for solving the above problems is as follows.
An intake port and an exhaust port provided in the main body case, an air flow path communicating the exhaust port and the air intake port, an evaporator disposed in the air flow path, and dew water generated in the evaporator. While storing, a drainage tank detachably mounted from a mounting opening provided in the main body case, and a cover having a drainage opening while covering the drainage tank upper surface, provided in the drainage tank bottom direction of the cover, A ridge formed in a direction intersecting with the attaching / detaching direction of the drainage tank.

In the first means or the second means for solving the above-mentioned problems, it is preferable that the ridge is extended to a position lower than a full water level of a drain tank.

[0008] In the first means or the second means for solving the above problems, it is preferable that a plurality of the ridges are provided.

Numeral denotes an air flow path connecting the intake port 8 and the exhaust port 9.

Reference numeral 11 denotes a blower disposed in the air flow passage 10, which is constituted by a motor 12 and a fan 13, sucks air from an intake 8 and exhausts air from an exhaust 9 through the air flow passage 10. It has become. Reference numeral 14 denotes a heat exchange unit disposed upstream of the blower unit 11, comprising a evaporator 15 and a condenser 16 disposed downstream of the evaporator 15, and standing on the upper surface of the partition plate 5. Is fixed by the supporting portion 17 and the holding portion 18 formed on one of the cases 2.

Reference numeral 19 denotes a handle provided on the upper surface of the main body case 1 so as to be capable of being turned upside down.
And a partition plate for partitioning into two rooms. The storage chamber 22 stores a drain tank 27 described below, which is detachably mounted via a mounting port 23 formed in the main body case 1, and the machine chamber 23 stores a compressor 24 described later. ing.

Reference numeral 24 denotes a compressor disposed in the machine room 23. The compressor 24 is connected to the condenser 16 and the evaporator 15 by piping (not shown), and circulates a refrigerant through the condenser 16 and the evaporator 15. ing.

The compressor 20 and the condenser 16 and the evaporator
By circulating the refrigerant through 15, the heat is released by the condenser 16 and the heat is absorbed by the evaporator 15, so that the air sucked into the main body case 1 from the intake port 8 passes through the evaporator 15. During the cooling, the moisture in the air is dehumidified by dew condensation on the surface of the evaporator 15, is heated when passing through the condenser 16, reduces the relative humidity, and is exhausted from the exhaust port 9. The dew water adhering to the surface of the evaporator 15 is dropped on the partition plate 5.

Reference numeral 25 denotes a recess formed in the partition plate 5 below the evaporator 15 so that dew condensation water dropped on the partition plate 5 from the evaporator 15 is collected. Reference numeral 26 denotes a drain hole formed substantially at the center of the recess 25.

Reference numeral 27 denotes a drainage tank which is detachably stored in the storage chamber 21 through the mounting opening 23, and the dew condensation water dropped on the partition plate 5 is guided to the drainage tank 27 through the drainage hole 26. ing. Reference numeral 28 denotes a handle provided on the drain tank 27.

Reference numeral 29 denotes a cover for covering the upper surface of the drain tank 27. The cover 29 has a drain opening 30 near the mounting opening 23. A guide hole 31 provided in the cover 29 is provided at a position facing the drain hole 26, and guides the condensed water dripped from the drain hole 26 into the drain tank 27. Reference numeral 32 denotes a plurality of ridges provided from the bottom surface of the cover 29 in the direction of the bottom surface of the drainage tank 27, the ridges being formed in a direction intersecting the attaching / detaching direction of the drainage tank 27, and extending below the full water level of the drainage tank 27. ing.

The drainage tank 27 is provided with a full-water detecting means (not shown) for detecting that the dew condensation water has accumulated in the drainage tank 27 up to a predetermined water level and notifying the user.

Reference numeral 33 denotes an operation unit provided above the main body case 1 on the surface of the drainage tank 27 on which the mounting port 23 is formed, a switch 34 for operating / stopping, a display unit for displaying an operation state (not shown), and a drainage unit. A full-water display unit and the like for notifying when the tank 27 is full is detected.

When the switch 34 of the operation unit 33 is operated, the air in the room is driven by the motor 12 to drive the main body case 1.
The air is taken into the main body case 1 through an intake port 8 provided in the main body case 1, and is dehumidified by dew condensation in an evaporator 15.
After being warmed up in the room, it is returned to the room through the exhaust port 9.

The water condensed in the evaporator 15 is dropped on the partition plate 5 as water droplets, and is discharged to a drain tank 27 via a drain hole 26 formed in the partition plate 5 and a guide hole 31 formed in the cover 29. run down. When a predetermined amount of condensed water accumulates in the drain tank 27, a control unit (not shown) stops the operation and turns on a full display unit (not shown) to notify that the drain tank 27 is full.

When the drainage tank 27 is pulled out of the main body case 1, water accumulated in the drainage tank 27 tends to move due to inertial force, but a ridge 32 formed in a direction intersecting with the mounting / dismounting direction of the drainage tank 27. This prevents the movement of water, keeps the water calm, and makes it difficult for water to spill out from the drainage opening 30 even when the water has accumulated near the full water level in the drainage tank 27.

Further, since a plurality of ridges 32 are provided, the water movement section in the drainage tank 27 is finely divided by the ridges 32 to reduce the amount of water movement. When the water collides with the ridge 32, the width of the water surface moving up and down can be reduced, and the quietness of the water can be improved.

In this embodiment, the drainage opening 30 is provided in the vicinity of the mounting port 23. However, the present invention is not limited to this. Even when the configuration is provided, the same operation and effect as in the present embodiment can be obtained.

[0025]

According to the structure of the first aspect of the present invention, when inertial force acts on the drainage tank, the ridge provided on the cover prevents the water in the drainage tank from moving. This has the effect of making it difficult for water to spill.

According to the structure of the second aspect of the present invention, when the drainage tank is pulled out of the main body case, the protrusion provided on the cover prevents movement of water in the drainage tank. This has the effect of making it difficult for water to spill.

According to the configuration of claim 3 of the present invention, since the ridge extends to a position lower than the full water level of the drainage tank, the movement section of water can be reduced, and the movement of water can be reduced. The effect is that the prevention can be surely prevented by the ridges.

According to the configuration of claim 4 of the present invention, since a plurality of ridges are provided in the drainage tank, the movement section of water can be reduced, and the calmness of water can be improved. It works.
