Laundry machine door assembly
A laundry machine comprising a housing, a drum in the housing, a door movable to close and open access to the drum, and a door latch assembly. The door latch assembly has a bolt that is movable between first and second bolt positions, with first position on a first travel path of the door, and the second position on a second travel path of the door. The door has a bolt handle connected to the bolt to move the bolt between the bolt positions. A catch is mounted within the first travel path and not within the second travel path, and configured to engage the bolt to exert an opening force opposing movement of the bolt along the first travel path upon movement of the door from the closed door position towards the open door position.
1. A laundry machine comprising:
a housing having an access opening;
a drum mounted within the housing and configured to rotate about a generally horizontal rotation axis, the drum comprising an open end located along the rotation axis and facing the access opening;
a door rotatably connected to the housing adjacent to the access opening, the door being movable between a closed door position in which the door closes the access opening, and an open door position in which the door does not close the access opening; and
a door latch assembly comprising:
a bolt movable between a first bolt position and a second bolt position, wherein the first bolt position is located on a first travel path defined by movement of the door between the closed door position and the open door position, and the second bolt position is located on a second travel path defined by movement of the door between the closed door position and the open door position,
a bolt handle having a grip portion that is accessible when the door is in the closed door position, the bolt handle being operatively connected to the bolt and configured to move the bolt from the first bolt position to the second bolt position, and
a catch mounted within the first travel path and not within the second travel path, the catch being configured to engage the bolt when the door is in the closed door position and the bolt is in the first bolt position, wherein the catch and bolt are configured to exert an opening force opposing movement of the bolt along the first travel path upon movement of the door from the closed door position towards the open door position, the bolt maintains the first travel path when engaging the catch,
wherein the bolt and the bolt handle are mounted to one of the door and the housing, and the catch is mounted to the other of the door and the housing.
2. The laundry machine of claim 1 , wherein the laundry machine comprises a forced-air drying system.
3. The laundry machine of claim 1 , wherein the bolt is mounted to move along a linear path between the first bolt position and the second bolt position.
4. The laundry machine of claim 3 , wherein the linear path extends from the first bolt position towards a rotation axis of the door.
5. The laundry machine of claim 3 , wherein the bolt is integrally formed with the bolt handle.
6. The laundry machine of claim 3 , wherein the bolt is connected to the bolt handle by an intermediate linkage.
7. The laundry machine of claim 1 , wherein the bolt is mounted to the door to move along a semicircular path about a bolt rotation axis between the first bolt position and the second bolt position.
8. The laundry machine of claim 7 , wherein the bolt rotation axis is parallel to a rotation axis of the door.
9. The laundry machine of claim 7 , wherein the bolt is integrally formed with the bolt handle.
10. The laundry machine of claim 7 , wherein the bolt is connected to the bolt handle by an intermediate linkage.
11. The laundry machine of claim 1 , wherein the catch is configured to exert a closing force opposing movement of the bolt along the first travel path upon movement of the door from the open door position to the closed door position.
12. The laundry machine of claim 11 , wherein the closing force is equal to the opening force.
13. The laundry machine of claim 1 , wherein the bolt is operatively connected to the door or the housing by a resilient member configured to exert an unlatching force opposing movement of the bolt from the first bolt position to the second bolt position.
14. The laundry machine of claim 13 , wherein the resilient member comprises a spring positioned between the door or the housing and at least one of the bolt and the bolt handle.
15. The laundry machine of claim 14 , wherein the spring is integrally formed with the bolt.
16. The laundry machine of claim 13 , wherein the unlatching force is less than the opening force.
17. The laundry machine of claim 16 , wherein the unlatching force is less than 5 pounds force, and the opening force is between 9 pounds force and 15 pounds force.
18. The laundry machine of claim 1 , wherein:
the bolt comprises an entry face directed towards the closed door position and an exit face directed towards the open door position; and
the catch comprises opposed leaf springs configured to be spread apart by the entry face upon movement of the door approaching the door closed position with the bolt in the first bolt position, and to move together to at least partially surround the exit face upon the door reaching the closed position with the bolt in the first bolt position.
19. The laundry machine of claim 18 , wherein:
the entry face comprises an entry wedge that tapers towards the closed door position to an entry wedge tip; and
the exit face comprises an exit wedge that tapers towards the open door position to an exit wedge tip.
20. The laundry machine of claim 19 , wherein the entry wedge tapers at a first angle, the exit wedge tapers at a second angle, and the first angle equals the second angle.
21. The laundry machine of claim 1 , wherein the bolt and the bolt handle are mounted to the door and the catch is mounted to the housing.
22. The laundry machine of claim 1 , wherein the bolt and the bolt handle are mounted to the housing and the catch is mounted to the door.
