Abstract
Abstract A water mixing device comprises a divided first chamber comprising an inlet chamber having hot and cold inlets for connection respectively to hot and cold water supplies and an outlet chamber having at least one outlet of the device, and a divided second chamber comprising at least two separate enclosures each having an outlet into the outlet chamber. A selector valve selectively permits water from the inlet chamber to flow through one or more of the enclosures of the second chamber, at least one of these enclosures being selectable by the selector valve to permit clear water to flow into the outlet chamber, and at least one other one of the enclosures having therein a container for receiving a soluble substance such as soap whereby in use of the device the water outflow of the device may be made to contain dissolved soluble substance.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
216 words
A water mixing device comprising a casing having a lower part and an upper part, said lower part having a divided first chamber comprising an inlet chamber having hot and cold inlets for connection respectively to hot and cold water supplies, an outlet chamber for said device having at least one outlet from the device and valve means for said at least one outlet, said upper part having a second chamber divided by at least one wall to form at least two separate enclosures each having a fixed outlet to said outlet chamber of said lower part, selector valve means in said upper part for selectively permitting water from said inlet chamber in said lower part to flow through at least one of said enclosures, said selector valve means having one position associated with at least one of said enclosures to permit clear water to flow through said fixed outlet into the outlet chamber of the lower part and at least one other one of said enclosures having therein removable means for receiving and containing a soluble substance whereby in use of the device the water outflow from said at least one outlet may be made to contain dissolved soluble substance, said device further comprising means to removably attach said device to a water supply facility.
Claim 2
Dependent Claim
216 words
A water mixing device comprising a casing having a lower part and an upper part, said lower part having a divided first chamber comprising an inlet chamber having hot and cold inlets for connection respectively to hot and cold water supplies, an outlet chamber for said device having at least one outlet from the device and valve means for said at least one outlet, said upper part having a second chamber divided by at least one wall to form at least two separate enclosures each having a fixed outlet to said outlet chamber of said lower part, selector valve means in said upper part for selectively permitting water from said inlet chamber in said lower part to flow through at least one of said enclosures, said selector valve means having one position associated with at least one of said enclosures to permit clear water to flow through said fixed outlet into the outlet chamber of the lower part and at least one other one of said enclosures having therein removable means for receiving and containing a soluble substance whereby in use of the device the water outflow from said at least one outlet may be made to contain dissolved soluble substance, said device further comprising means to removably attach said device to a water supply facility.
Claim 3
Dependent Claim
46 words
The water mixing device of claim 1 wherein said outlet chamber has one outlet to a bathing facility and one outlet to a shower facility, said outlet valve means being associated with the two outlets for selecting which outlet provides the water outflow from the device.
Claim 4
Dependent Claim
54 words
The water mixing device of claim 1 wherein said at least one wall dividing wall of the divided second chamber is arranged for cooperating with the selector valve means for permitting water to flow into either one of the enclosures formed on each side of a wall, or to flow into both such enclosures.
Claim 5
Dependent Claim
99 words
The water mixing device of claim 3 wherein the selector valve means comprises a hollow, generally cylindrical member mounted for angular movement by operation of an external control member within a cylindrical space adjacent the end of said aT least one dividing wall of said divided second chamber, the hollow, generally cylindrical member being open at one end and in communication with said inlet chamber, and having at least one aperture in its cylindrical wall whereby water can flow into one or more of said enclosures as aforesaid, in accordance with the angular position of the generally cylindrical member.
Claim 6
Dependent Claim
60 words
The water mixing device of claim 1 wherein said enclosures are positioned relative to the outlet chamber such that in the operative position of the device, the outlets of the enclosures are above the outlet chamber, the outlets of the enclosures being in the lowermost walls of said enclosures whereby drainage of the enclosures into the outlet chamber takes place.
Claim 7
Dependent Claim
44 words
The water mixing device of claim 1 wherein said means for receiving a soluble substance comprises a container for a solid soluble substance, said container being removable from said enclosure through an opening in the external wall of the upper part of the device.
Claim 8
Dependent Claim
27 words
The water mixing device of claim 6 wherein there are three of said enclosures, two of said enclosures being provided with containers for a solid soluble substance.
Claim 9
Dependent Claim
59 words
The water mixing device of claim 6 wherein each container, comprises a hollow member at least partially open at one end to receive the solid soluble substance and to permit water to flow into the container in use of the device, and having therein an aperture spaced from said one end for positioning adjacent the outlet of an enclosure.
Claim 10
Dependent Claim
67 words
The water mixing device of claim 8 wherein the enclosure for receiving a container has an aperture in an external wall of the device for receiving a container, the end wall of said container remote from the open end thereof being adapted to sealingly engage said extenal wall, the container and said external wall having means for locking the container in sealing engagement with the external wall.
Claim 11
Dependent Claim
29 words
The water mixing device of claim 9 wherein said container has a circular end wall, and said means for locking the container in sealing engagement comprises bayonet-type locking means.
Claim 12
Dependent Claim
