Abstract

A shower head has an array of spray nozzles arranged over an outlet face. A first set of nozzles is connected to a cold water supply to provide cold water spray nozzles, and a second set of the nozzles is connected to a hot water supply to provide hot water spray nozzles. A third set of nozzles surrounds the hot and cold water nozzles, and is connected to a mixed water supply at a temperature between the hot and cold water temperatures.

Claims

1. A shower head, comprising:

a hollow outer housing having an outlet face, and an array of hot water, mixed water, and cold water nozzles arranged over the outlet face;

a hot water inlet, a mixed water inlet, and a cold water inlet connected to the hot water, mixed water, and cold water nozzles, respectively, for supplying water at a first, hot temperature to the hot water nozzles, at a second, cold temperature to the cold water nozzles, and at a third temperature between the hot and cold water temperatures to said mixed water nozzles; and

the hot and cold water nozzles alternating across the outlet face of the shower head.

2. The shower head as claimed in claim 1, wherein the outlet face has an outer periphery and an inner area, the mixed water nozzles are arranged at spaced intervals around the periphery of the outlet face to surround the inner area of the outlet face, and the alternating hot and cold nozzles are located within the inner area surrounded by the mixed water nozzles.

3. The shower head as claimed in claim 1, wherein each spray nozzle provides a very straight, thin spray perpendicular to the outlet face.

4. The shower head as claimed in claim 3, wherein each spray nozzle is adjustable to provide an outlet spray in a range of angles from a straight spray up to a cone-shaped spray which will intersect with adjacent sprays.

5. The shower head as claimed in claim 4, wherein each spray nozzle is adjustable to provide an outlet spray in a range of angles from 0°

to 15°

.

6. The shower head as claimed in claim 1, including a valve assembly having a first inlet passageway for connection to a cold water supply, a second inlet passageway for connection to a hot water supply, the first inlet passageway being connected to the cold water inlet, and the second inlet passageway being connected to the hot water inlet, the valve assembly further comprising a first valve in the first inlet passageway for controlling cold water supply to the cold water inlet and a second valve in the second inlet passageway for controlling hot water supply to the hot water inlet.

7. The shower head as claimed in claim 6, wherein the housing has a mixed water inlet, and the valve assembly includes third and fourth passageways connecting the first and second passageways to the mixed water inlet, and third and fourth valves in the third and fourth passageways for controlling the mixture of hot and cold water supplied to the mixed water inlet.

8. The shower head as claimed in claim 7, wherein the valve assembly includes fifth and sixth passageways connecting the hot and cold water supplies, respectively, to the mixed water inlet, and fifth and sixth valves, located in the fifth and sixth passageway, respectively, for selectively supplying a mixture of hot and cold water to the hot and cold spray nozzles.

9. A shower head for spraying water in a plurality of streams, comprising:

a hollow outer housing having an outlet face;

a plurality of spray nozzles spaced over the outlet face, the nozzles comprising a first set of cold water nozzles for supplying a water spray at a first temperature, a second set of hot water nozzles for supplying a water spray at a second temperature higher than the first temperature, and a third set of mixed water nozzles for supplying water at a third temperature between the first and second temperatures;

the housing having a first inlet connected to said cold water nozzles, a second inlet connected to said hot water nozzles, and a third inlet connected to said mixed water nozzles;

a cold water supply connected to said first inlet;

a hot water supply connected to said second inlet; and

a valve assembly connected between said cold and hot water supplies and said third inlet for supplying a mixture of hot and cold water to said third inlet.

10. The shower head as claimed in claim 9, wherein the outlet face has a perimeter and the third set of nozzles are arranged around the perimeter of the outlet face.

11. The shower head as claimed in claim 10, wherein the hot and cold nozzles are arranged in an area enclosed by the third set of nozzles.

12. The shower head as claimed in claim 11, wherein the hot and cold nozzles alternate across said area.

13. The shower head as claimed in claim 9, wherein said valve assembly includes a valve means for selectively supplying a mixture of hot and cold water to said first and second inlets.

14. The shower head as claimed in claim 9, wherein each nozzle is adjustable to provide a spray over a selected range of angles.

15. The shower head as claimed in claim 9, wherein said housing has an integral handle for gripping by a user when showering.
