This relates to devise a bottled water dispenser hot tub, the body is formed to pass through the upper two halves separated by a vertical while the bottom trough is made and the connection flange to the upper end of the cylinder are formed through the bottom, while the O-ring to increase the adhesion between the O-rings trapezoidal in the upper and lower flanges of the cylinder groove is formed, the flange of the lower barrel of the O-ring groove in the circumferential direction on the outside and a predetermined plurality of locking projections disposed with a spacing it is provided, in the upper flange of the tube is arranged at a predetermined interval in the circumferential direction on the outside of the O-ring groove engaging shoulder of the lower cylinder The structure consists of a stumbling block for the group having a plurality of irregularities which hung on, it hung on the obstacle of the upper jaw locking cylinder groups through bottom flange at the flange and the state is closely abutting each other through the upper part of the lower barrel across the O-ring can be combined is off. The bottled water dispenser of the designed structure of the hot water tank made of such a construction is not only to create a clean and sanitary hot water tank and is easy to remove the water formed by drawing to form a vertical tube, the upper and lower cylinder when it is necessary to clean the hot water tank simply to get the convenience that will not be easily separated or concluded through an obstacle jams formed on the tip of the upper and lower jaws and rotated through.
