DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dehumidifier according to one embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a main body, in which a refrigerating cycle is formed by connecting an evaporator 2, a condenser 3, and a compressor 7 with a refrigerant pipe 8 in the main body 1. Reference numeral 4 denotes a water receiving tray which is provided below the evaporator 2 and has a cylindrical drain port 5. Reference numeral 6 denotes a drain tank provided below the drain port 5. In the drain tank 6, there is a fullness detection mechanism 20 for detecting the fullness of the stored drain water. Reference numeral 18 denotes a wind suction port, and 19 denotes an air outlet. 16 is a ventilation circuit, and 17 is a fan. Reference numeral 13 denotes a lever for closing the drain port 5 through a stopper 11, and reference numeral 21 denotes an arm integrally formed with the lever 13. The arm 21 is configured to contact the upper part in the depth direction of the drainage tank 6. A spring 22 is provided to press the stopper 11 attached to the lever 13 against the drain port 5. Reference numeral 23 denotes a substrate of the main body 1 on which the drainage tank 6 is mounted.

FIG. 2 is a partial cross-sectional view taken from the main body 1 to drain the drain water stored in the drain tank 6.

FIG. 3 is a partial sectional view in which the drainage tank 6 is set on the main body 1. FIG. 4 is an enlarged view near the drain port 5 of FIG.

FIGS. 5A and 5B are a single-part view (A) of the spring 22 and an operation view (B) when the spring 22 is pressed against the drain port 5.

FIG. 6 is a perspective view of the lever 13, in which a pair of shafts 24 are provided at the center and an arm 21 is provided at the rear. There are three notches 15 at the front, and an air inlet / outlet 25 penetrating the center of the notch 15.

FIG. 7 is a perspective view (A) and a longitudinal sectional view (B) of the plug 11.

FIG. 8 is a perspective view (E) and a longitudinal sectional view (F) of the plug 11 of claim 8.

FIG. 9 is a partial sectional view of the main body 1 to which the drain receiver 12 of claim 2 is attached.

FIG. 10 is a partial sectional view after the drainage tank 6 of FIG. 9 is taken out.

FIG. 1 shows the dehumidifier configured as described above.
The operation will be described with reference to FIG.

When the compressor 7 and the fan 17 are operated,
The air in the living room passes through the suction port 18, is dehumidified by the evaporator 2, is heated by the condenser 3, is returned to the living room from the outlet 19 as dry air, and is dehumidified. At this time, evaporator 2
Drain water generated in the above passes through the water receiving tray 4 and drain port 5
Through the drainage tank 6. When the stored drain water gradually increases and the full water detection mechanism 20 in the drain tank 6 operates, the dehumidifying operation is stopped, the user is notified of the full water by a lamp or the like (not shown), and the drain in the drain tank 6 is drained. Encourages drainage of water. Then, the user takes out the drainage tank 6 from the main body 1 and drains the drain water. At this time, as shown in FIGS. 2 and 3, or withdrawn drainage tank 6 half, since the drain port 5 is closed by a plug 11 be or pulled out completely, adhering to the evaporator 2 and the water receiving tray 4 The drain water does not drop from the drain port 5, so that the floor surface does not get wet with the drain water.

At this time, make sure that the stopper 11 is
It is indispensable that they are actually fitted,
According to the present invention, the lower part of the stopper 11 has a claw shape 14 and
A notch 15 is provided in the bar 13 so that
The stopper 11 and the lever 13
To the accuracy set at the design stage.
Therefore, it can be in close contact with the drain port 5 with high accuracy
Therefore, the drain port is reliably closed.

Here, the shape of the stopper 11 is as shown in FIG.
In addition to the shape that is convex upward, it can be almost spherical or roughly bowl-shaped
The point is, if the drain port 5 can be securely closed
Good.

Further, the drainage tank 6 is not mounted.
When the spring to apply press lever 13 to the drain port 5 2
2, the drain water is more reliably supplied into the water receiving tray 4.
You will be able to water.

In addition, with the structure as shown in FIG.
Since the capacity of the drain 12 is made larger than the amount of the drain water dropped from the drain port 5 at the time of draining the drain water from the drain tank 6, the dropped drain water does not overflow from the drain receiver 12, so that the floor Does not wet the surface.

In the present embodiment, the air enters and exits from the lever 13.
A hole 25 is formed, and a space formed by the stopper 11 and the lever 21
It was configured so that the air could easily enter and exit. This
Thereby, the stopper 11 is formed into a film shape with a flexible material.
When formed, it is formed by lever 21 and stopper 11
Since the escape of the air by the expansion and contraction of the plug 11 can be reliably performed in the small space, the plug 11 can smoothly return to the original shape, and the reliability of closing the drain port 5 is improved .

[0030]

As described above, according to the present invention, the following
It has the following effects.

That is, the lever provided below the drain port is
A notch is provided, and a stopper with a claw-shaped lower part is cut out of the lever.
By fitting to each other
Even if the drain tank is not set on the main unit.
It can be configured to prevent dripping of ren water
In both cases, place the stopper on the lever to ensure that the drain port can be closed.
Accurately and easily at the position (center) as designed
Can be Also, the stopper has a claw shape and notch for the lever.
Parts are fixed by fitting
The number is small.

The lever has a notch as well as air.
The access hole prevents the plug from closing the drain port.
Small space formed by the stopper and the lever when deformed according to
Easily escape the internal air from between and fill the drain port
Order to thereby Itto, between more plug and drain port
Can be improved. Also,
If an empty drain tank is installed and the plug is away from the drain port
In this case, the air smoothly flows into the small space,
The shape easily returns to its original shape and closes the drain port again.
Reliability at the time of providing for

The upper part is open at the tip of the lever.
A drain receiver is provided, and the inner volume of the drain receiver is
When the compressor stops and drains the drain water from the drain tank
The amount of drain water dropped from the drain port
As a result, when the drain tank was removed,
The generated drain water is temporarily stored in the drain receiver.
Holding, overflow of dehumidified water from the water pan
And drain water overflows on the floor, etc.
Can be prevented.
