Abstract

A household appliance for cleaning laundry includes a rinsing container that collects rinsing liquid generated during a cleaning process, a controller that stores a connection type of a rinsing liquid device during an initial commissioning of the rinsing liquid device, and one of a collection container that collects rinsing liquid after cleaning a heat exchanger of a heat pump and a connection to an external waste water system that disposes of the rinsing liquid after cleaning the heat exchanger based upon the connection type stored by the controller.

Claims (39)

1. A household appliance for cleaning laundry comprising:

a rinsing liquid device including a collection container and a rinsing container contained therein that collects rinsing liquid generated during a cleaning process and guides the rinsing liquid through a heat exchanger of a heat pump; and

a controller that stores a connection type information of the rinsing liquid device during an initial commissioning of the rinsing liquid device,

wherein the controller is configured to cause automatic disposal of the rinsing liquid guided through the heat exchanger into one of the collection container and an external waste water system based upon the connection type stored information by the controller.

2. The household appliance of claim 1 , wherein liquid overflowing from the rinsing container automatically runs into the collection container.

3. The household appliance of claim 1 , further comprising:

a floor assembly in communication with the collection container and the external waste water system, the floor assembly configured to collect the liquid drained from the collection container.

4. The household appliance of claim 1 , wherein the lowest point of the collection container has a closure configured for one of:

movement to an open position during the initial commissioning of the rinsing liquid device in order to drain the liquid collected in the collection container if the rinsing liquid device is connected to the external waste water system; and

movement to a closed position during the initial commissioning of the rinsing liquid device if the rinsing liquid device is not connected to the external waste water system.

5. A household appliance for cleaning laundry comprising:

a rinsing liquid device including a collection container and a rinsing container contained in the collection container, the rinsing container configured to collect liquid generated during a cleaning process and also positioned in the collection container such that overflowing liquid therein automatically flows into the collection container;

a heat exchanger of a heat pump in communication with the rinsing container such that the liquid in the rinsing container is guiding therethrough to clean the heat exchanger;

a controller that stores a connection type information of the rinsing liquid device during an initial commissioning of the rinsing liquid device;

a floor assembly in communication with the collection container and which collects the liquid used to clean the heat exchanger; and

a sensor connected to the controller and which detects a fill level of the liquid collected in the floor assembly such that the controller initiates automatic draining of the liquid in the floor assembly when a fill level threshold value is reached.

6. The household appliance of claim 5 , further comprising:

an external waste water system in communication with the floor assembly.

7. The household appliance of claim 6 , wherein, based upon the connection type stored by the controller, the rinsing liquid guided through the heat exchanger is subsequently automatically guided for rinsing liquid disposal purposes from the floor assembly into one of:

the collection container; and

the external waste water system.

8. The household appliance of clam 5 , wherein the sensor is provided in the floor assembly.

9. A method for operating a rinsing liquid device in a household appliance for cleaning pieces of laundry, the rinsing liquid device including a collection container and a rinsing container contained therein, the method comprising:

storing, in a controller, a connection type information of the rinsing liquid device during an initial commissioning of the rinsing liquid device;

collecting condensate generated during a cleaning process as rinsing liquid in the rinsing container;

guiding the condensate, from the rinsing liquid device through a heat exchanger of a heat pump, to an operating phase for removing lint from the heat exchanger of the heat pump; and

automatically disposing the rinsing liquid guided through the heat exchanger into one of the collection container and an external waste water system based upon the connection type information stored in the controller during the initial commissioning of the rinsing liquid device.

10. The method of claim 9 , further comprising initializing commission of the rinsing liquid device by specifically actuating a control element of the household appliance.

11. The method of claim 10 , further comprising opening a closure on a lowest point in the collection container during the initializing commission to drain condensate collected in the collection container if the rinsing liquid device is connected to the external waste water system for condensate disposal purposes.

12. The method of claim 9 , further comprising overflowing condensate out of a filled washing container into the collection container.

13. The method of claim 9 , wherein the guiding of the rinsing liquid comprises guiding rinsing liquid and condensate collected in the collection container into a trap of the external waste water system if the rinsing liquid device is connected to the external waste water system.

14. The method of claim 9 , wherein the guiding the rinsing liquid comprising guiding the rinsing liquid into the collection container after passing through the heat exchanger if the rinsing liquid device is not connected to the external waste water system for liquid disposal purposes.

15. The method of claim 9 , further comprising guiding the rinsing liquid into a floor assembly of the household appliance after passing through the heat exchanger before guiding into the external waste water system or the collection container as a function of the connection type of the rinsing liquid device.

16. The method as claimed in claim 15 , further comprising detecting a fill level increasing in the floor assembly as a result of the inflowing liquid from the rinsing container and the collection container and draining the liquid collected in the floor assembly only when a fill level threshold value is reached.

17. The method of claim 16 , further comprising pumping the rinsing liquid collected in the floor assembly until a number of rinsing cycles is terminated.

18. The method of claim 9 , further comprising:

rinsing the heat exchanger a first time;

guiding the rinsing liquid back into the rinsing container; and

rinsing the heat exchanger a second time before the guiding of the rinsing liquid into one of the collection container and the external waste water system.
