Abstract

A dryer appliance and a method of operating a dryer appliance are provided. The dryer includes a drum defining a drying chamber rotatably mounted within a cabinet, an additive dispensing assembly to provide a dryer additive to the drying chamber, and a controller for initiating a drying operation. The controller obtains washer operating parameters from a washing machine, determines a drying operation based on the received parameters, initiates a dry cycle, and directs a dryer additive to be dispensed based on the dryer operating schedule.

Claims (41)

1 . A dryer appliance comprising:

a cabinet;

a drum rotatably mounted within the cabinet, the drum defining a drying chamber for receipt of clothes for drying;

an additive dispensing assembly positioned within the cabinet and configured to selectively provide a dryer additive to the drying chamber; and

a controller in operable communication with the additive dispensing assembly, the controller being configured to initiate a drying operation comprising:

obtaining washer operating parameters from a washing machine appliance,

determining a dryer operating schedule based on obtaining the washer operating parameters,

initiating a dry cycle for a laundry load, and

directing a dispensing action of the dryer additive at the additive dispensing assembly based on the dryer operating schedule.

2 . The dryer appliance of claim 1 , wherein the washing machine appliance is linked to the dryer appliance.

3 . The dryer appliance of claim 2 , wherein at least one of the washing machine appliance and the dryer appliance is linked to a consumer device.

4 . The dryer appliance of claim 1 , wherein determining the dryer operating schedule comprises determining an amount of water to be removed from the laundry load in response to obtaining washer operating parameters.

5 . The dryer appliance of claim 1 , wherein directing the dispensing action comprises:

retrieving a dry weight of the laundry load in response to washer operating parameters;

determining an additive volume of the dryer additive based on the dry weight of the laundry load; and

dispensing the additive volume from the additive dispensing assembly to the drying chamber.

6 . The dryer appliance of claim 5 , wherein determining the additive volume comprises selecting the additive volume from a plurality of predetermined volumes.

7 . The dryer appliance of claim 6 , wherein each of the plurality of predetermined volumes correlates to a specific dry laundry weight.

8 . The dryer appliance of claim 1 , wherein the drying operation further comprises:

determining a frequency of additive additions; and

determining a dispense time within the dry cycle for adding the additive following the determination of the dryer operating schedule.

9 . The dryer appliance of claim 1 , wherein the dryer additive comprises a perfume or odor neutralizer.

10 . A method of operating a dryer appliance comprising a cabinet, a drum defining a drying chamber, and an additive dispensing assembly, the method comprising:

obtaining washer operating parameters from a washing machine appliance;

determining a dryer operating schedule based on obtaining washer operating parameter;

initiating a dry cycle for a laundry load following obtaining the washer operating parameters; and

directing a dispensing action of a dryer additive at the additive dispensing assembly based on the dryer operating schedule.

11 . The method of claim 10 , wherein the washing machine appliance is linked to the dryer appliance.

12 . The method of claim 11 , wherein at least one of the washing machine appliance and the dryer appliance is linked to a consumer device.

13 . The method of claim 10 , wherein determining the dryer operating schedule comprises determining an amount of water to be removed from the laundry load in response to obtaining washer operating parameters.

14 . The method of claim 10 , wherein directing the dispensing action comprises:

determining a dry weight of the laundry load in response to washer operating parameters;

determining an additive volume of the dryer additive based on the dry weight of the laundry load; and

dispensing the additive volume from the additive dispensing assembly to the drying chamber.

15 . The method of claim 14 , wherein determining the additive volume comprises selecting the additive volume from a plurality of predetermined volumes.

16 . The method of claim 15 , wherein each predetermined volume of the plurality of predetermined volumes correlates to a specific dry laundry weight.

17 . The method of claim 10 , further comprising:

determining a volume of additive to be added;

determining a frequency of additive additions; and

determining a dispense time within the dry cycle for adding the additive following the determination of the dryer operating schedule.

18 . The method of claim 10 , wherein the dryer additive comprises a perfume or odor neutralizer.
