In addition, the one end of the inlet connection channel 221 and the heating channel RH are connected reliably and naturally, while the contact area between the heat transfer member 410 and the inlet / outlet connection member 220 can be minimized.

Thus, even if the water-absorbent sealing connecting member 220 is made of silicon as described above, it is possible to minimize the occurrence of a toxic smell due to the heating of the heating unit 400. In addition, the hardening of the water supply hose connecting member 220 by long-term use can be minimized, so that the sealing connection between the inlet 210 and one end of the heating channel RH can be reliably performed.
