Claims20
A fabric treating appliance comprising a treating chamber for receiving fabric for treatment and a treating chemistry dispenser, the treating chemistry dispenser comprising:
- at least one cup with a bottom wall;
- a siphon tube projecting upwardly from the bottom wall for removal of treating chemistry from the at least one cup during a dispensing operation;
- a cover for the siphon tube;
- at least one water inlet;
- and
- a liquid distribution header located above the bottom wall and fluidly coupled with the at least one water inlet for distributing water to the at least one cup, the liquid distribution header comprising:
- a chamber overlying the at least one cup;
- at least one raised water outlet hole located in the chamber downstream of the water inlet and fluidly coupled to the at least one cup;
- at least one water outlet slot located in the chamber downstream of the at least one raised water outlet hole and fluidly coupled to the at least one cup;
- raised portions located in the chamber on opposite sides of the at least one of the at least one raised hole or the at least one slot to define a channel for channeling a flow of water across the liquid distribution header from the at least one water inlet toward at least one of the at least one raised outlet hole or at least one slot;
- and
- wherein water supplied to the liquid distribution header through the at least one water inlet is supplied to the at least one cup through at least one of the at least one raised outlet hole or the at least one slot.
