Abstract

An additive dispenser of a washing appliance is provided herein. The additive dispenser may include a water inlet and a drawer frame. The water inlet may be positioned upstream from a wash chamber. The drawer frame may define a compartment to receive an additive pod. The compartment may be positioned in downstream fluid communication with the water inlet. The drawer frame may include a sidewall at least partially enclosing the compartment.

First claim

What is claimed is:

1. An additive dispenser for a washing appliance for providing a wash fluid to a wash chamber of the washing appliance, the additive dispenser comprising:
a water inlet positioned upstream from the wash chamber; and
a drawer frame defining a compartment to receive an additive pod, the compartment being positioned in downstream fluid communication with the water inlet on a flow path extending along a transverse direction from the water inlet, the drawer frame comprising a sidewall at least partially enclosing the compartment, the sidewall extending along the transverse direction between a front end and a rear end, the sidewall extending along a lateral direction between a first side and a second side, the front end defining a pair of adjacent concave surfaces facing the compartment, the pair of adjacent concave surfaces forming an interior wedge positioned rearward relative to a concave vertex of each concave surface, and the rear end defining a wash fluid outlet positioned in fluid communication between the compartment and the wash chamber,
wherein the water inlet is coaxial along the transverse direction with the wash fluid outlet, and
wherein the water inlet is defined by a water supply conduit selectively received through the wash fluid outlet.

2. The additive dispenser of claim 1 , wherein the wash fluid outlet is aligned with the interior wedge along the transverse direction.

3. The additive dispenser of claim 1 , wherein the water inlet is aligned with the interior wedge along the transverse direction.

4. The additive dispenser of claim 1 , wherein the water supply conduit is fixedly mounted to a shower plate, and wherein the drawer frame is slidably mounted on the shower plate to selectively move thereon along the transverse direction.

5. The additive dispenser of claim 1 , wherein the interior wedge comprises a shared vertex formed by an abutment between the pair of adjacent concave surfaces.

6. The additive dispenser of claim 1 , wherein the water supply conduit comprises a needle tip extending forward from the water inlet to puncture the additive pod within the compartment.

7. An additive dispenser for a washing appliance for providing a wash fluid to a wash chamber of the washing appliance, the additive dispenser comprising:
a water inlet positioned upstream from the wash chamber;
a drawer frame defining a compartment to receive an additive pod, the compartment being positioned in downstream fluid communication with the water inlet, the drawer frame comprising a sidewall at least partially enclosing the compartment, the sidewall extending along a transverse direction between a front end and a rear end, the sidewall extending along a lateral direction between a first side and a second side, the front end defining a pair of adjacent concave surfaces facing the compartment, the pair of adjacent concave surfaces forming an interior wedge positioned rearward relative to a concave vertex of each concave surface, and the rear end defining a wash fluid outlet positioned in fluid communication between the compartment and the wash chamber and coaxial along the transverse direction with the water inlet; and
a water supply conduit defining the water inlet positioned upstream from the wash chamber,
wherein the drawer frame is horizontally slidable relative to the water supply conduit between an open position and a closed position, the open position permitting receipt of the additive pod within the compartment, the closed position permitting greater receipt of the water supply conduit in the compartment than the open position.

8. The additive dispenser of claim 7 , wherein the water supply conduit comprises a needle tip extending forward from the water inlet to puncture the additive pod within the compartment.

9. The additive dispenser of claim 7 , wherein the wash fluid outlet is aligned with the interior wedge along the transverse direction.

10. The additive dispenser of claim 7 , wherein the water inlet is aligned with the interior wedge along the transverse direction.
