## Abstract

An ozone laundry system that injects ozone into the chemical injection system in order to allow the system to inject ozone as other cleaning chemicals are injected into the washer. This allows ozone to be injected through the wash cycle rather than just during the initial fill phase and additional avoids the expense and maintenance of adding ozone recirculation plumping to an ozone laundry system. Accordingly, ozone levels may be maintained at superior levels throughout the wash cycle.

## Claims

### Claim at position 1

1-19. (canceled)

### Claim 20

An ozone laundry system comprising:
a wash drum;
a wash water fill system in fluid communication with the wash drum;
a chemical injection system in fluid communication with the wash drum and being configured to deliver a mixture of water and chemicals to the wash drum; and
an ozone generator configured to introduce ozone into the mixture of water and chemicals within the chemical injection system prior to the mixture of water and chemicals being delivered to the wash drum.

### Claim 21 (depends on 20)

The ozone laundry system of claim 20, wherein the ozone generator is a UV ozone generator.

### Claim 22 (depends on 20)

The ozone laundry system of claim 20, wherein the ozone generator is a gas ozone generator.

### Claim 23 (depends on 20)

The ozone laundry system of claim 20, wherein the ozone generator is an electrolytic ozone generator.

### Claim 24 (depends on 20)

The ozone laundry system of claim 20, wherein the ozone gas generator is in fluid communication with a venturi system configured to introduce ozone into the chemical injection system.

### Claim 25 (depends on 20)

The ozone laundry system of claim 20, wherein the venturi system is configured to introduce ozone into the mixture of water and chemicals downstream of a flush manifold of the chemical injection system.

### Claim 26 (depends on 20)

The ozone laundry system of claim 20, wherein the venturi system introduces ozone into a water supply line of the chemical injection system that is positioned upstream of a flush manifold of the chemical injection system.

### Claim 27 (depends on 20)

The ozone laundry system of claim 20, wherein the chemical injection system includes a pump in fluid communication with a water supply line to pump only water through a flush manifold of the chemical injection system.

### Claim 28 (depends on 20)

The ozone laundry system of claim 20, wherein the system is configured to maintain ozone levels in the wash drum at about 1 ppm throughout a wash cycle.

### Claim 29 (depends on 20)

The ozone laundry system of claim 20, wherein the system is configured to maintain ozone levels in the wash drum at between about 0.5 ppm and about 2.0 ppm throughout a wash cycle.
