ABSTRACT:
A hot and cold water mixing device which comprises one or more valve units each constituted by accommodating an operating member within a hollow casing, and a housing into which the one or more valve units are inserted and arranged and in which two primary water passages communicating with a hot water supply source and a cold water supply source, respectively, are formed. The housing is composed of an outer housing (1) and an inner housing (2) which is inserted into the outer housing and which is formed with water holes (11,12,13) communicating with said valve units, and at least two primary water passages (5,6) are formed between the outer housing and the inner housing by separating members (3). Further, since the hot water passage (5) and the cold water passage (6) are formed between the outer casing (1) and the inner housing (2) using separating members (13), the primary water passages can easily be formed and, simultaneously, the construction of the mixing device can be simplified and the assembling and disassembling operations can be facilitated.
