In addition, the cooling unit may prevent the odor from being oversaturated in the storage water by supplying fresh water to the water tank, and may prevent deterioration of the odor removal performance.

Here, the water tank 610 is preferably composed of a first water tank 611 to which the air inlet pipe 620 is connected, and a second water tank 612 to accommodate the storage water overflowed from the first water tank 611. More preferably, the circulation unit 630 is provided in the second water tank 612.

It is a circulation unit for circulating and circulating the storage water to the first water tank 611 and the air inlet pipe 620 to immerse the air containing the odor introduced through the air inlet pipe 620 to the water tank 610 By separating the second tank 612 is provided with 630, the immersion operation of the air containing the odor and the circulation flow operation of the storage water is to be made smoothly without mutual interference.

In addition, the circulation unit 630 is provided at one side of the second tank 612 and a pump 631 for pumping the stored water in the second tank 612 and pumped from the pump 631. It may be configured to include a circulation pipe 632 for circulating flow of the stored water to the air inlet pipe 620.

The circulation unit 630 configured as described above includes air containing odors flowing in the air inlet pipe 620 by flowing the storage water (circulating water) of the second water tank 612 to the air inlet pipe 620. It also serves to condense faster, but as the circulating water is discharged from the circulation pipe 632 to the downstream side of the air inlet pipe 620, the predetermined air flow by the water flow inside the air inlet pipe 620 By forming a serves to guide the air containing the odor inside the drying chamber 510 is naturally sucked into the air inlet pipe 620.

Here, the end of the circulation pipe 632 connected to the air inlet pipe 620 is preferably installed to face the downstream side of the air inlet pipe 620, the storage discharged from the circulation pipe 632 The circulation pipe 632 distributes and distributes the circulation water in order to more smoothly and strongly generate the water flow by the water. To this end, in the present embodiment, it is more preferable that a split 635 member is installed at the end of the circulation pipe 632 to branch the stored water.

Of course, other circulators that force the flow of air instead of the circulation unit, for example, a device such as a blowing fan may be used to flow air containing odor from the drying chamber to the odor removing unit.

As the second water tank 612 is connected to the sewage pipe 15, the second water tank 612 may discharge the storage water overflowed from the second water tank 612 to the sewage pipe 15.

In addition, the air outlet 512 of the drying chamber 510 is inclined upward so that the air containing the odor discharged to the air inlet pipe 620 condensed upwards so as not to be introduced into the drying chamber 510 inside the drying chamber 510. Is preferably provided.
