Abstract

A fluid delivery assembly for a shower includes a waterway assembly, a spray head, and a water treatment assembly. The spray head is configured to receive fluid from the waterway assembly and deliver fluid from an outlet. The water treatment assembly is configured to provide a treatment to the fluid of the waterway assembly.

Claims

1. A fluid delivery assembly for a shower comprising:

a waterway assembly;

a spray head configured to receive fluid from the waterway assembly and deliver fluid from an outlet;

a water treatment assembly configured to provide a treatment to the fluid of the waterway assembly to decrease at least one of bacteria, mold, germs, and viruses within the spray head;

a user input device configured to receive an input of a user to switch between a plurality of operating modes of the spray head, the operating modes of the spray head including a showering mode and a water treatment mode;

a controller operably coupled to the user input device, the controller configured to control output of the treatment from the water treatment assembly according to the operating mode of the spray head in response to the user input device; and

wherein the water treatment mode includes a spray head water treatment mode and a shower enclosure water treatment mode, the spray head water treatment mode permits the water treatment assembly to treat residual water left standing in the spray head after a previous use, the spray head treatment mode comprising a first concentration output of the treatment for a first time duration, the shower enclosure treatment mode comprising a second concentration output of the treatment for a second time duration, the first concentration output of the treatment being greater than the second concentration output of the treatment, and the first time duration being less than the second time duration.

2. The fluid delivery assembly of claim 1, wherein the water treatment assembly includes an indicating member configured to indicate the operating mode of the spray head.

3. The fluid delivery assembly of claim 1, wherein the controller controls the output of the treatment according to at least one of a concentration output of the treatment, a water temperature, and a time duration of the treatment.

4. The fluid delivery assembly of claim 3, wherein the controller is configured to prevent the output of the treatment when at least one of the treatment concentration, the water temperature, and the time duration is greater than a predetermined amount.

5. The fluid delivery assembly of claim 4, wherein the time duration of the treatment is between one second and ten minutes.

6. The fluid delivery assembly of claim 1, wherein the treatment is an ozone treatment.

7. The fluid delivery assembly of claim 1, wherein the short duration of the spray head water treatment mode comprises 1-10 seconds of application of the treatment.
