Abstract

A dryer appliance and additive dispensing assembly is generally provided herein. The additive dispensing assembly may be positioned within the cabinet and configured to provide an additive mist to the drum. The additive dispensing assembly may include a supply conduit, an additive dispenser, and a siphon channel. The supply conduit may extend between a fluid supply and the drum. The additive dispenser may store and dispense a dryer additive. The siphon channel may extend from the additive dispenser to the supply conduit downstream from the fluid supply. An initial flow of fluid directed through the supply conduit may create a siphon that draws the dryer additive into the supply conduit to mix with the flow of fluid and create an additive flow that is dispensed into the drum.

First claim

What is claimed is:

1. A dryer appliance comprising:
a cabinet;
a drum rotatably mounted within the cabinet, the drum defining a space for the receipt of clothes for drying; and
an additive dispensing assembly positioned within the cabinet and configured to provide an additive mist to the drum, the additive dispensing assembly comprising
a supply conduit extending between a fluid supply and the drum,
an additive dispenser for storing and dispensing a dryer additive, and
a siphon channel extending from the additive dispenser to the supply conduit downstream from the fluid supply,
wherein an initial flow of fluid directed through the supply conduit creates a siphon that draws the dryer additive into the supply conduit to mix with the flow of fluid and create an additive flow that is dispensed into the drum.

2. The dryer appliance of claim 1 , wherein the fluid supply is an air supply, and wherein the additive dispensing assembly further comprises an air handler in fluid communication between the air supply and the supply conduit to motivate the initial fluid flow through the supply conduit.

3. The dryer appliance of claim 1 , wherein the additive dispensing assembly further comprises a piston in fluid communication between the fluid supply and the supply conduit to motivate the initial fluid flow through the supply conduit.

4. The dryer appliance of claim 1 , wherein the fluid supply is a water supply.

5. The dryer appliance of claim 1 , further comprising a heater positioned in thermal communication with the supply conduit upstream from the siphon channel.

6. The dryer appliance of claim 1 , further comprising an atomizer nozzle positioned in fluid communication between the supply conduit and the drum, the atomizer nozzle being downstream from the siphon channel.

7. The dryer appliance of claim 1 , wherein the supply conduit includes a Venturi nozzle downstream from the fluid supply to receive the siphon channel.

8. The dryer appliance of claim 1 , wherein the dryer additive comprises a perfume, a UV fabric protector, or a wrinkle release fluid.

9. The dryer appliance of claim 1 , further comprising a controller configured to selectively direct the initial flow of fluid.

10. An additive dispensing assembly for providing an additive mist to a drum of a dryer appliance, the additive dispensing assembly comprising
a supply conduit extending between a fluid supply and the drum,
an additive dispenser for storing and dispensing a dryer additive, and
a siphon channel operably coupling the additive dispenser to the supply conduit downstream from the fluid supply such that an initial flow of fluid directed through the supply conduit creates a siphon that draws the dryer additive into the supply conduit to mix with the flow of fluid and create an additive flow, and
a misting assembly in operable communication with the supply conduit to vaporize the additive flow to the additive mist that is dispensed into the drum.

11. The additive dispensing assembly of claim 10 , wherein the fluid supply is an air supply, and wherein the additive dispensing assembly further comprises an air handler in fluid communication between the air supply and the supply conduit to motivate the initial fluid flow through the supply conduit.

12. The additive dispensing assembly of claim 10 , further comprising a piston in fluid communication between the fluid supply and the supply conduit to motivate the initial fluid flow through the supply conduit.

13. The additive dispensing assembly of claim 10 , wherein the fluid supply is a water supply.

14. The additive dispensing assembly of claim 10 , wherein the misting assembly comprises a heater positioned in thermal communication with the supply conduit upstream from the siphon channel.

15. The additive dispensing assembly of claim 10 , wherein the misting assembly comprises an atomizer nozzle positioned in fluid communication between the supply conduit and the drum, the atomizer nozzle being downstream from the siphon channel.

16. The additive dispensing assembly of claim 10 , wherein the supply conduit includes a Venturi nozzle downstream from the fluid supply to receive the siphon channel.

17. The additive dispensing assembly of claim 10 , wherein the dryer additive comprises a perfume, a UV fabric protector, or a wrinkle release fluid.

18. The additive dispensing assembly of claim 10 , further comprising a controller configured to selectively direct the initial flow of fluid.
