A sanitary thermostatic mixing valve, comprising:
- lower, intermediate and upper baseplates, which are assembled superimposed along an assembly axis and which each have lower and upper faces axially opposite each other, so that the upper face of the lower baseplate and the lower face of the intermediate baseplate are applied axially against each other and the upper face of the intermediate baseplate and the lower face of the upper baseplate are applied axially against each other,
- a thermostatic cartridge which:
- is assembled to at least one of the lower, intermediate and upper baseplates so that the thermostatic cartridge is actuatable from the upper face of the upper baseplate,
- provided with a cold water inlet and a hot water inlet, which are axial, and with a mixed water outlet, which is transverse to the assembly axis,
- is suitable for mixing a cold water flow from the cold water inlet of the thermostatic cartridge and a hot water flow from the hot water inlet of the thermostatic cartridge, for forming a mixed water flow sent to the mixed water outlet of the thermostatic cartridge, and
- incorporates a thermostatic regulation member, suitable for regulating the temperature of the mixed water flow by varying respective flow rates of the cold water flow and of the hot water flow, and
- one or more flow members which:
- are assembled to at least one of the lower, intermediate and upper baseplates so that the one flow member or each of the flow members is actuatable from the upper face of the upper baseplate,
- are each provided with a mixed water inlet, which is transverse to the assembly axis, and at least one mixed water outlet, and
- are each suitable for controlling a flow rate of a mixed water flow crossing through the flow member between the mixed water inlet and the at least one mixed water outlet of the flow member,
- wherein the lower baseplate delimits both a cold water inlet duct, a hot water inlet duct and at least one mixed water return duct, all of which open onto the upper face of the lower baseplate, the at least one mixed water outlet of the one or more flow members being connected to the at least one mixed water return duct,
- wherein the intermediate baseplate delimits a cold water conveying duct and a hot water conveying duct, which:
- each connect the lower and upper faces of the intermediate baseplate to each other,
- are, at the lower face of the intermediate baseplate, abutted against the cold water and hot water inlet ducts, respectively,
- are, at the upper face of the intermediate baseplate, abutted against the hot and cold water inlets, respectively, of the thermostatic cartridge, and
- are each internally fitted with a non-return valve,
- and wherein the upper face of the intermediate baseplate and the lower face of the upper baseplate jointly delimit a mixed water passage duct, which extends lengthwise transversely to the assembly axis so that, at one of the two opposite longitudinal ends of the mixed water passage duct, the mixed water passage duct is abutted against the mixed water outlet of the thermostatic cartridge, while at the other of the two opposite longitudinal ends of the mixed water passage duct, the mixed water passage duct is abutted against the mixed water inlet of the one flow member or of each of the flow members.
