Abstract

An improved appliance is provided for easy and controlled movement of the door from a closed position to an open position. The appliance includes a door pivotally mounted over an access opening. A gas-charged cylinder or strut is mounted within the appliance and connected to one end of a lever arm, with the other end of the lever arm being connected to the door. A push-push latch normally retains the door in a closed position. A person can easily push on the door to release the latch, after which the cylinder arm is automatically extended to move the door to the open position. The door, cylinder and latch combination of the present invention can be used on top-loading and front-loading appliances and appliances with doors pivotal about horizontal and vertical axes.

Claims

1. An improved top-loading clothes washer or dryer appliance having a cabinet with an interior chamber, an upwardly facing access opening to provide access to the chamber, and a door pivotally connected to the cabinet for movement between a closed position covering the opening and an open position exposing the opening, the improvement comprising:

a cylinder mounted to the cabinet and having an extensible arm;

a lever arm having a first end connected to the door, a second end connected to the cylinder arm, and a portion defining a pivot axis between the first and second ends; and

whereby extension of the cylinder arm moves the lever arm so as to move the door upwardly to the open position.

2. The improved appliance of claim 1 wherein the first and second ends of the lever arm are angularly disposed with respect to one another.

3. The improved appliance of claim 1 wherein the cylinder is a gas-charged strut.

4. The improved appliance of claim 1 wherein the cylinder normally biases the door to an open position.

5. The improved appliance of claim 1 further comprising a latch for retaining the door in the closed position.

6. The improved appliance of claim 5 wherein the latch is a push-push latch.

7. A method of opening a door on a top-loading clothes washer or dryer appliance comprising:

pushing on the door to release a latch normally holding the door in a closed position; and

applying a biasing force to the door to automatically urge the door upwardly to an open position.

8. The method of claim 7 wherein the biasing force is applied by a gas-charged cylinder.

9. The method of claim 7 wherein the biasing force is applied from within the appliance.
