Abstract

A dehumidifier appliance including a cabinet defining an airflow path; a water tank removably mounted within the cabinet below the airflow path; a first connector provided within the cabinet, the first connector comprising a pair of receiving pins and a pair of first magnets; a second connector provided within the water tank and configured to mate with the first connector, the second connector comprising a pair of contact pins and a pair of second magnets; and a controller configured to perform an operation. The operation includes determining that a first circuit between the pair of first magnets and the pair of second magnets is closed; initiating a dehumidifying cycle; determining that a second circuit between the pair of receiving pins and the pair of contact pins is closed; and implementing a responsive action in response to determining that the second circuit is closed.

Claims (54)

1 . A dehumidifier appliance defining a vertical direction, a lateral direction, and a transverse direction, the dehumidifier appliance comprising:

a cabinet defining an airflow path that extends between an air inlet and an air outlet spaced apart from the air inlet;

a water tank removably mounted within the cabinet below the airflow path;

a first connector provided within the cabinet, the first connector comprising a pair of receiving pins and a pair of first magnets;

a second connector provided within the water tank and configured to mate with the first connector, the second connector comprising a pair of contact pins and a pair of second magnets; and

a controller in operative communication with the first connector, the controller configured to perform an operation, the operation comprising:

determining that a first circuit between the pair of first magnets and the pair of second magnets is closed;

initiating a dehumidifying cycle;

determining that a second circuit between the pair of receiving pins and the pair of contact pins is closed; and

implementing a responsive action in response to determining that the second circuit is closed.

2 . The dehumidifier appliance of claim 1 , wherein the cabinet comprises a rear wall, and wherein the first connector is attached to the rear wall.

3 . The dehumidifier appliance of claim 2 , wherein the first connector comprises:

a body, wherein the pair of receiving pins and the pair of first magnets are received within the body; and

a fastener selectively coupling the body to the rear wall.

4 . The dehumidifier appliance of claim 1 , wherein each of the pair of receiving pins is spring loaded within the first connector along the transverse direction.

5 . The dehumidifier appliance of claim 1 , wherein each of the pair of contact pins comprises:

a first end exposed within the water tank; and

a second end opposite the first end exposed toward the cabinet, wherein the second end of each of the pair of contact pins is configured to selectively mate with the pair of receiving pins.

6 . The dehumidifier appliance of claim 1 , wherein the pair of first magnets selectively attracts the pair of second magnets when the water tank is inserted into the cabinet.

7 . The dehumidifier appliance of claim 1 , further comprising:

an air handler operably coupled to the airflow path for selectively urging a flow of air therethrough; and

a refrigeration assembly mounted within the cabinet along the airflow path for selectively dehumidifying the flow of air.

8 . The dehumidifier appliance of claim 7 , wherein initiating the dehumidifying cycle comprises:

directing the air handler at a predetermined speed; and

energizing the refrigeration assembly to circulate a refrigerant.

9 . The dehumidifier appliance of claim 8 , wherein the responsive action comprises:

terminating the air handler; and

de-energizing the refrigeration assembly.

10 . A method of operating a dehumidifier appliance, the dehumidifier appliance comprising a first connector comprising a pair of first magnets and a pair of receiving pins and a second connector comprising a pair of second magnets and a pair of contact pins, the method comprising:

determining that a first circuit between the pair of first magnets and the pair of second magnets is closed;

initiating a dehumidifying cycle;

determining that a second circuit between the pair of receiving pins and the pair of contact pins is closed; and

implementing a responsive action in response to determining that the second circuit is closed.

11 . The method of claim 10 , wherein the dehumidifier appliance further comprises:

a cabinet comprising a rear wall; and

a water tank removably mounted within the cabinet, and wherein the first connector is attached to the rear wall adjacent the water tank.

12 . The method of claim 11 , wherein the first connector comprises:

a body, wherein the pair of receiving pins and the pair of first magnets are received within the body; and

a fastener selectively coupling the body to the rear wall.

13 . The method of claim 11 , wherein each of the pair of receiving pins is spring loaded within the first connector along a transverse direction.

14 . The method of claim 11 , wherein each of the pair of contact pins comprises:

a first end exposed within the water tank; and

a second end opposite the first end exposed toward the cabinet, wherein the second end of each of the pair of contact pins is configured to selectively mate with the pair of receiving pins.

15 . The method of claim 11 , wherein the pair of first magnets selectively attracts the pair of second magnets when the water tank is inserted into the cabinet.

16 . The method of claim 11 , wherein the dehumidifier appliance further comprises:

an airflow path formed within the cabinet;

an air handler operably coupled to the airflow path for selectively urging a flow of air therethrough; and

a refrigeration assembly mounted within the cabinet along the airflow path for selectively dehumidifying the flow of air.

17 . The method of claim 16 , wherein initiating the dehumidifying cycle comprises:

directing the air handler at a predetermined speed; and

energizing the refrigeration assembly to circulate a refrigerant.

18 . The method of claim 17 , wherein the responsive action comprises:

terminating the air handler; and

de-energizing the refrigeration assembly.
