The through hole 63 is formed with an inclined surface extending upward so that the condensed water generated in the heat exchanger 40 does not flow out to the outside while passing through the through hole 63 and falls downward. In addition, a seating groove 68 formed to be recessed is formed in the lower portion of the through-hole 63. Also, as shown in FIG. 6, a horizontal system for sensing the horizontal is mounted on the lower surface of the seat.

When the hot water is transferred to the cold / hot water pipe of the heat exchanger 40, the air around the heat exchanger 40 is cooled. When the air is cooled down below the dew point, condensation water is generated by the condensation phenomenon do. The condensed water thus generated passes through the through-hole 63 and falls into the drain 70.

As shown in FIG. 2, the drag dome 70 has a shape in which an upper portion is opened and a side surface and a bottom surface are closed, and the bottom surface is formed obliquely. Therefore, when the condensed water falls onto the drainage 70, it is discharged naturally to the outside along the inclined bottom surface. The drainage member (70) is seated in the seating groove (68) of the seat (60).

The drainage member 70 is formed of a transparent polycarbonate (PC) material so that it can be lightened and visually confirmed whether the contaminant is present in the drainage member 70.

A support groove 28 is formed on one side of the housing 20 in which the side surface of the heat exchanger 40 and the side surface of the seat 60 are inserted and seated. Therefore, the connection and separation of the cold / hot water pipe connected to the heat exchanger is facilitated.

The lower plate 51 is made of a foamed polypropylene (EPP) material. The foamed polypropylene (EPP) has appropriate strength, flexibility and elasticity. Therefore, it is possible to prevent fatigue caused by vibration. The lower plate 51 according to the present invention may be formed of a transparent synthetic resin material.
