PROBLEM TO BE SOLVED: To increase the degree of freedom in designing the main body and improve the appearance by preventing the guide section from being seen outside the reservoir by setting the guide section at a position where it is hidden from view when the reservoir is fixed to a given position in the main body led by the guide section the main body is provided with. SOLUTION: A main body 21 is provided with a hooking section 21b as well as a guide section 21a which has a taper section with which a reservoir 22 is fixed. At the same time, a taper section 22a, which is set alongside the taper section of the guide section 21a, and a rib 22b to hook onto the hooking section 21b are formed on the reservoir 22, and a backflow-preventive valve is disposed in the bottom of the reservoir 22. This backflow-preventive valve 23 is so constituted that it is released when the reservoir 22 is mounted onto the main body 21 led by the guide section 21a, and is connected with the heater section 25 by way of a hot-water duct 24. When the reservoir 22 is mounted in this way, the guide section and the fixing section of the reservoir 22 do not show themselves outside the reservoir 22, thus making it possible to mount the reservoir 22 onto the main body 21 without impairing its appearance. |
