Many domestic appliances, such as built in ovens, have one or more doors that swing open about a horizontal axis such that the door swings downward into an open position. Such a door is often heavy and uses springs of significant strength to counteract a portion of the weight of the door so that it is easier for a user to open and close the door. These springs often act to slam the door into the closed position after the door has passed a particular rotational position when moved upward toward the closed position. This slamming is undesirable for at least the reasons that it can make a loud noise, it can damage the appliance over time, and it gives the appearance of low quality. The result of such slamming is usually that the user continues to hold the door until it has reached the closed position.
To prevent the undesirable slamming, soft-close hinges can be employed. Soft-close hinges often include some type of damper that slows the movement of the door for a predetermined distance before the door reaches the closed position. This damping prevents the slamming of the door and results in a much more desirable appliance.
