According to a fourth aspect of the present invention, in the water purification apparatus, a purifying material supporting member having a plurality of small holes is mounted on the most upstream side of the purifying material storing section, and an upstream end face of the purifying material storing section is provided. A gap is provided between the low-pressure-loss purifying material, and a plurality of rectifying plates protruding from the purifying material storage unit entrance in the gap and erected in the radial direction and covering the upper ends of all the rectifying plates. By providing the top plate, the hot and cold water is guided by the rectifying plate and the top plate into the gap between the purification material support member that supports the bottom of the low pressure loss type purification material and the bottom surface of the purification material storage unit. With low resistance, it can be spread over the entire lower end of the purifying material storage part, and the hot water can be evenly supplied from the entire lower end of the purifying material to the upper side. Power can be exerted effectively to improve purification efficiency. Can.

In the water purifying apparatus according to the fifth aspect of the present invention, the main body lower end and the main body upper end are provided with slits communicating with the inside of the main body outer peripheral wall. The air inside the outer peripheral wall of the main unit escapes from the slit and hot water easily enters from the slit at the lower end of the main unit. When the main unit is taken out of the bathtub, air enters through the slit provided at the upper end of the main unit and enters the outer peripheral wall of the main unit. The hot and cold water is discharged from the slit at the lower end of the main body, so that the inside of the apparatus main body can be easily evacuated and drained, so that the water purification device can be easily taken in and out of the bathtub, and the usability of the water purification device can be improved. it can.
