In the dehumidifier 20, the air sucked from the suction port 21 is purified by the filter 22 and cooled by the evaporator 3 of the refrigeration cycle including the compressor 1, the condenser 2, the evaporator 3 and the capillary tube 4. It is dehumidified, further heated by the condenser 2 and blown out from the outlet 24 by the fan 23.

The refrigeration cycle is operated by driving the compressor 1.

The drain water generated by the cooling and dehumidifying of the evaporator 3 is collected by the dew tray 5 which receives the drain water, and from the tip of the drain port 5a provided at the bottom of the dew tray 5 as shown in FIG. As shown in (3), it is dropped (dropped) and stored in the drain tank 6 which is a container.

The drain water storage device of this dehumidifier is composed of the dew tray 5 and the drain tank 6, and the tip of the drain port 5a of the dew tray 5 is obliquely cut and is also obliquely cut. A protruding portion 6a for receiving the drain water to be dripped is formed on the upper portion of the inner wall of the drain tank 6 so as to be close to the most distal end of the drain port 5a.

Therefore, the drain water collected by the dew tray 5 travels along the most distal end of the drain port 5a and falls onto the projecting portion 6a.

As a result, the drop of the drain water flowing down is small, and the dropping sound of the dropping drain water is a very small sound that cannot be heard by the ear.

[0010]

However, in the conventional drain water storage device, it is necessary to provide the protruding portion 6a of the drain tank 6 at a position higher than a certain extent in order to reduce the dropping noise of the drain water. There is the following problem because the protruding portion 6a is projected inside the tank 6.

That is, the protruding portion 6a must protrude its tip to a position beyond the drain port 5a, and in order to prevent the drain water from directly dripping on the water surface in the drain tank 6 or the bottom surface of the drain tank 6, The dripping surface of the drain water has to be a gentle sloping surface, and the sloping surface for guiding the water from the dripping surface to the bottom of the drain tank 6 must be a steep sloping surface, which requires a large dead space.

For a large amount of drain water that comes out at 2.1 degrees, water drops may drop directly from the sloped surface, which is the dropping surface of the protrusion 6a, to the water surface, which may cause drop noise. is there.

3. It is difficult to clean the inside of the drain tank 6.

4. The shape of the drain tank 6 becomes distorted and the commercial value drops.

5. When the water surface is higher than the protruding portion 6a, a dropping sound of water drops is generated.

In view of the above problems, it is an object of the present invention to provide a drain water storage device capable of preventing the generation of drain water dropping noise and reducing the dead space of the container. Further, another object of the present invention is to provide a drain water storage device capable of reliably preventing the generation of dropping noise even for a large amount of drain water.
