Door-locking device for a household appliance, door arrangement comprising a door-locking device and method for locking a door of a household appliance
A door locking device for a household appliance is provided. The door locking device includes a base member that has a receptacle; a closing element on a door side that is moved into the receptacle when a door of the household appliance is closed; a control unit; an electrical switch that is switched over in a closed position of the closing element and via which an information signal signaling the closed position of the closing element is transmitted to the control unit; and an interlocking device to mechanically interlock the door. The mechanical interlocking of the door is facilitated in an interlock position of the closing element and the closing element is moved from the interlock position into the closed position when the door is closed.
1. A door locking device for a household appliance, the door locking device comprising
a base member having a receptacle;
a closing element adapted to be on a door of the household appliance, the closing element being moved into the receptacle when the door is closed;
a control unit;
an electrical switch that is switched over after the closing element is in a closed position and via which an information signal signaling the closed position of the closing element is transmitted to the control unit, the electrical switch being configured to open and close by way of the closing element contacting and moving an element of the door locking device; and
an interlocking device adapted to mechanically interlock the door;
wherein mechanical interlocking of the door is facilitated in an interlock position of the closing element; and
wherein the closing element is moved from the interlock position into the closed position when the door is closed.
2. The door locking device of claim 1 , wherein, in a closed position of the closing element, the electrical switch is switched over into a closed switching state.
3. The door locking device of claim 1 , wherein, in an open position of the closing element, the electrical switch is switched over when the door is opened, and wherein the closing element is moved from the interlock position into the open position when the door is opened.
4. The door locking device of claim 3 , wherein, in an open position of the closing element, the electrical switch is switched over into an open switch state when the door is opened.
5. The door locking device of claim 1 , wherein the electrical switch is a spring switch with hysteresis.
6. The door locking device of claim 1 , wherein the electrical switch comprises a contact element pair, and wherein one contact element of the contact element pair is connected via a spring element to an actuation element that is actuated at least indirectly by the closing element.
7. The door locking device of claim 1 , wherein the element is a sliding element that is moved by the closing element relative to the base member and by which the electrical switch is switched.
8. The door locking device of claim 7 , wherein the sliding element has a flange-type projection that protrudes from the sliding element and by means of which the electrical switch is switched.
9. The door locking device of claim 7 , wherein the sliding element has a receptacle opening for accepting the closing element, and wherein the sliding element is moved by exerting a force on a side wall of the receptacle opening that is caused by the closing element.
10. The door locking device of claim 7 , wherein the interlocking device has an opening that is formed in the sliding element and into which, in the interlock position of the closing element, a corresponding interlocking element is introduced.
11. The door locking device of claim 10 , wherein the corresponding interlocking element is a locking bolt.
12. The door locking device of claim 1 , further comprising an electrical interlocking switch that is switched into a closed switching state when the door is interlocked.
13. The door locking device of claim 1 , wherein the household appliance is a laundry care household appliance.
14. A door arrangement for a household appliance, the door arrangement comprising:
a door with a closing element; and
a household appliance-side door locking device, the door locking device comprising:
a base member having a receptacle into which the closing element on a door side is moved when the door of the household appliance is closed;
a control unit;
an electrical switch that is switched over after the closing element is in a closed position and via which an information signal signaling the closed position of the closing element is transmitted to the control unit, the electrical switch being configured to open and close by way of the closing element contacting and moving an element of the door locking device; and
an interlocking device to mechanically interlock the door;
wherein mechanical interlocking of the door is facilitated in an interlock position of the closing element; and
wherein the closing element is moved from the interlock position into the closed position when the door is closed.
15. The door locking device of claim 1 , wherein the electrical switch is actuated by way of movement of the closing element within the receptacle.
16. The door locking device of claim 1 , wherein a switching characteristic of the switching element has hysteresis in relation to a current position of the closing element.
17. The door locking device of claim 16 , further comprising an actuation element that actuates the electrical switch and the hysteresis is caused by the actuating element.
18. The door locking device of claim 14 , wherein the electrical switch is actuated by way of movement of the closing element within the receptacle.
19. The door locking device of claim 14 , wherein a switching characteristic of the switching element has hysteresis in relation to a current position of the closing element.
