Abstract

A drain cleaner apparatus for dispensing a cleaning composition into a condensate drain line of an air handler of an air conditioning system. The drain cleaner apparatus includes an apparatus reservoir configured to hold the cleaning composition, a connector interface configured to couple with the condensate drain line to cause an apparatus outlet of the drain cleaner apparatus to be in fluid communication with an opening of the condensate drain line, a dispenser device that is configured to be actuated to selectively dispense an amount of the cleaning composition from the apparatus reservoir and through the apparatus outlet, and a controller configured to actuate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention.

Claims (51)

1. A drain cleaner apparatus for dispensing a cleaning composition into a condensate drain line of an air handler of an air conditioning system, the drain cleaner apparatus comprising:

an apparatus outlet that is configured to be in fluid communication with an opening of the condensate drain line based on the drain cleaner apparatus being coupled to the opening of the condensate drain line;

a dispenser device that is configured to be actuated to selectively dispense an amount of the cleaning composition through the apparatus outlet;

a controller configured to actuate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention; and

a moisture sensor configured to generate a signal based on contacting condensate backup in the condensate drain line.

2. The drain cleaner apparatus of claim 1 , wherein the dispenser device includes at least one valve that is configured to be selectively opened based on a control signal generated by the controller to establish a flow path through the at least one valve to the apparatus outlet.

3. The drain cleaner apparatus of claim 1 , wherein the dispenser device includes a pump that is configured to operate for a particular period of time based on a control signal generated by the controller to move the amount of the cleaning composition to the apparatus outlet.

4. The drain cleaner apparatus of claim 1 , further comprising:

a structure connector that is configured to connect the drain cleaner apparatus to an external structure to at least partially hold the drain cleaner apparatus in place in relation to the opening of the condensate drain line.

5. The drain cleaner apparatus of claim 1 , wherein the drain cleaner apparatus is configured to cause at least a portion of the air conditioning system to shut down in response to the signal generated by the moisture sensor.

6. The drain cleaner apparatus of claim 1 , wherein the drain cleaner apparatus is configured to cause a float switch of the air handler to actuate to cause at least a portion of the air conditioning system to shut down based on the signal generated by the moisture sensor.

7. The drain cleaner apparatus of claim 1 , further comprising:

a network communication interface device that is configured to establish a network communication link with a remote computing device,

wherein the controller is configured to transmit a warning signal to the remote computing device via the network communication link based on the signal generated by the moisture sensor.

8. The drain cleaner apparatus of claim 1 , wherein

the drain cleaner apparatus is configured to detachably couple with a cartridge, the cartridge including

a cartridge reservoir configured to hold the cleaning composition, and

a cartridge outlet, and

the drain cleaner apparatus is configured to detachably couple with the cartridge such that the cartridge reservoir is in fluid communication with the dispensing device via the cartridge outlet.

9. The drain cleaner apparatus of claim 8 , wherein the drain cleaner apparatus or the cartridge includes a check valve that is configured to open in response to the drain cleaner apparatus detachably coupling with the cartridge to establish the fluid communication between the dispenser device and the cartridge reservoir of the cartridge via the cartridge outlet.

10. The drain cleaner apparatus of claim 9 , wherein the controller is configured to repeatedly actuate the dispenser device at a fixed time interval that is an elapse of a particular period of time, based on

monitoring a timer that increments a timer value at a fixed frequency,

actuating the dispenser device in response to the timer value reaching a particular time value corresponding to the elapse of the particular period of time, and

resetting the timer value to an initial timer value in response to actuating the dispenser device.

11. The drain cleaner apparatus of claim 10 , wherein the controller is configured to

monitor a counter that increments a counter value in response to each actuation of the dispenser device, and

generate a depletion signal in response to the counter value reaching a particular counter value that corresponds to at least partial depletion of a fixed reservoir of the cleaning composition.

12. The drain cleaner apparatus of claim 11 , further comprising:

a counter reset interface that is configured to cause the counter value to be reset to an initial counter value in response to human interaction with the counter reset interface.

13. The drain cleaner apparatus of claim 11 , further comprising:

a network communication interface device that is configured to establish a network communication link with a remote computing device,

wherein the controller is configured to

cause the depletion signal to be transmitted to the remote computing device via the network communication link, and

cause the counter value to be reset to an initial counter value in response to receiving a reset signal from the remote computing device via the network communication link.

14. A method for operating a drain cleaner apparatus, the drain cleaner apparatus configured to be coupled with a condensate drain line of an air handler of an air conditioning system such that an apparatus outlet of the drain cleaner apparatus is in fluid communication with an opening of the condensate drain line, the method comprising:

controlling a dispenser device of the drain cleaner apparatus to cause the dispenser device to selectively dispense an amount of a cleaning composition through the apparatus outlet without manual intervention; and

generating a signal at a moisture sensor of the drain cleaner apparatus in response to the moisture sensor contacting condensate backup in the condensate drain line.

15. The method of claim 14 , further comprising:

causing at least a portion of the air conditioning system to shut down based on processing the signal generated by the moisture sensor.

16. The method of claim 14 , further comprising:

causing a float switch of the air handler to actuate to cause at least a portion of the air conditioning system to shut down based on processing the signal generated by the moisture sensor.

17. The method of claim 14 , further comprising:

repeatedly actuating the dispenser device at a fixed time interval that is an elapse of a particular period of time, based on

monitoring a timer that increments a timer value at a fixed frequency,

actuating the dispenser device in response to the timer value reaching a particular time value corresponding to the elapse of the particular period of time, and

resetting the timer value to an initial timer value in response to actuating the dispenser device.

18. The method of claim 17 , further comprising:

monitoring a counter that increments a counter value in response to each actuation of the dispenser device, and

generating a depletion signal in response to the counter value reaching a particular counter value that corresponds to at least partial depletion of a fixed reservoir of the cleaning composition.

19. The method of claim 18 , further comprising:

causing the counter value to be reset to an initial counter value in response to receiving a reset signal.
